This initial phase, which may last as long as a week, typically begins with any or all of the following symptoms: fever, malaise, lack of appetite, muscle aches, headache, nausea, and vomiting. Other symptoms appearing less frequently include sore throat, cough, joint pain, chest pain, testicular pain, and parotid (salivary gland) pain. \n \nFollowing a few days of recovery, a second phase of illness may occur. Symptoms may consist of meningitis (fever, headache, stiff neck, etc.), encephalitis (drowsiness, confusion, sensory disturbances, and\/or motor abnormalities, such as paralysis), or meningoencephalitis (inflammation of both the brain and meninges). LCMV has also been known to cause acute hydrocephalus (increased fluid on the brain), which often requires surgical shunting to relieve increased intracranial pressure. In rare instances, infection results in myelitis (inflammation of the spinal cord) and presents with symptoms such as muscle weakness, paralysis, or changes in body sensation. An association between LCMV infection and myocarditis (inflammation of the heart muscles) has been suggested. \n \nPrevious observations show that most patients who develop aseptic meningitis or encephalitis due to LCMV survive. No chronic infection has been described in humans, and after the acute phase of illness, the virus is cleared from the body. However, as in all infections of the central nervous system, particularly encephalitis, temporary or permanent neurological damage is possible. Nerve deafness and arthritis have been reported. \n \nWomen who become infected with LCMV during pregnancy may pass the infection on to the fetus. Infections occurring during the first trimester may result in fetal death and pregnancy termination, while in the second and third trimesters, birth defects can develop.

All household members and other close contacts should be checked; those persons with evidence of an active infestation should be treated. Some experts believe prophylactic treatment is prudent for persons who share the same bed with actively-infested individuals. All infested persons (household members and close contacts) and their bedmates should be treated at the same time. \n \nSome pediculicides (medicines that kill lice) have an ovicidal effect (kill eggs). For pediculicides that are only weakly ovicidal or not ovicidal, routine retreatment is recommended. For those that are more strongly ovicidal, retreatment is recommended only if live (crawling) lice are still present several days after treatment (see recommendation for each medication). To be most effective, retreatment should occur after all eggs have hatched but before new eggs are produced. \n \nWhen treating head lice, supplemental measures can be combined with recommended medicine (pharmacologic treatment); however, such additional (non-pharmacologic) measures generally are not required to eliminate a head lice infestation. For example, hats, scarves, pillow cases, bedding, clothing, and towels worn or used by the infested person in the 2-day period just before treatment is started can be machine washed and dried using the hot water and hot air cycles because lice and eggs are killed by exposure for 5 minutes to temperatures greater than 53.5\u00b0C (128.3\u00b0F). Items that cannot be laundered may be dry-cleaned or sealed in a plastic bag for two weeks. Items such as hats, grooming aids, and towels that come in contact with the hair of an infested person should not be shared. Vacuuming furniture and floors can remove an infested person's hairs that might have viable nits attached. \n \n \nTreatment of the infested person(s): Requires using an Over-the-counter (OTC) or prescription medication. Follow these treatment steps: \n \n - Before applying treatment, it may be helpful to remove clothing that can become wet or stained during treatment. \n - Apply lice medicine, also called pediculicide, according to the instructions contained in the box or printed on the label. If the infested person has very long hair (longer than shoulder length), it may be necessary to use a second bottle. Pay special attention to instructions on the label or in the box regarding how long the medication should be left on the hair and how it should be washed out.\n \n \n \n \n \n \n - Have the infested person put on clean clothing after treatment. \n - If a few live lice are still found 8\u201312 hours after treatment, but are moving more slowly than before, do not retreat. The medicine may take longer to kill all the lice. Comb dead and any remaining live lice out of the hair using a fine\u2013toothed nit comb. \n - If, after 8\u201312 hours of treatment, no dead lice are found and lice seem as active as before, the medicine may not be working. Do not retreat until speaking with your health care provider; a different pediculicide may be necessary. If your health care provider recommends a different pediculicide, carefully follow the treatment instructions contained in the box or printed on the label. \n - Nit (head lice egg) combs, often found in lice medicine packages, should be used to comb nits and lice from the hair shaft. Many flea combs made for cats and dogs are also effective. \n - After each treatment, checking the hair and combing with a nit comb to remove nits and lice every 2\u20133 days may decrease the chance of self\u2013reinfestation. Continue to check for 2\u20133 weeks to be sure all lice and nits are gone. Nit removal is not needed when treating with spinosad topical suspension. \n - Retreatment is meant to kill any surviving hatched lice before they produce new eggs. For some drugs, retreatment is recommended routinely about a week after the first treatment (7\u20139 days, depending on the drug) and for others only if crawling lice are seen during this period. Retreatment with lindane shampoo is not recommended. \n \n \n \nSupplemental Measures: Head lice do not survive long if they fall off a person and cannot feed. You don't need to spend a lot of time or money on housecleaning activities. Follow these steps to help avoid re\u2013infestation by lice that have recently fallen off the hair or crawled onto clothing or furniture. \n \n - \nMachine wash and dry clothing, bed linens, and other items that the infested person wore or used during the 2 days before treatment using the hot water (130\u00b0F) laundry cycle and the high heat drying cycle. Clothing and items that are not washable can be dry\u2013cleaned \nOR \nsealed in a plastic bag and stored for 2 weeks. \n - Soak combs and brushes in hot water (at least 130\u00b0F) for 5\u201310 minutes. \n - Vacuum the floor and furniture, particularly where the infested person sat or lay. However, the risk of getting infested by a louse that has fallen onto a rug or carpet or furniture is very low. Head lice survive less than 1\u20132 days if they fall off a person and cannot feed; nits cannot hatch and usually die within a week if they are not kept at the same temperature as that found close to the human scalp. Spending much time and money on housecleaning activities is not necessary to avoid reinfestation by lice or nits that may have fallen off the head or crawled onto furniture or clothing. \n - Do not use fumigant sprays; they can be toxic if inhaled or absorbed through the skin. \n \n \n \n \n \nPrevent Reinfestation: \n \nMore on: Prevention & Control \n \n \n \n Over-the-counter Medications \n \nMany head lice medications are available \"over-the-counter\" without a prescription at a local drug store or pharmacy. Each over-the-counter product approved by the FDA for the treatment of head lice contains one of the following active ingredients. If crawling lice are still seen after a full course of treatment contact your health care provider. \n \n - \nPyrethrins combined with piperonyl butoxide;\n Brand name products: A\u2013200*, Pronto*, R&C*, Rid*, Triple X*, Licide* \nPyrethrins are naturally occurring pyrethroid extracts from the chrysanthemum flower. Pyrethrins are safe and effective when used as directed. Pyrethrins can only kill live lice, not unhatched eggs (nits). A second treatment is recommended 9 to 10 days after the first treatment to kill any newly hatched lice before they can produce new eggs. Pyrethrins generally should not be used by persons who are allergic to chrysanthemums or ragweed. Pyrethrin is approved for use on children 2 years of age and older. \n - \nPermethrin lotion, 1%;\n Brand name product: Nix*. \nPermethrin is a synthetic pyrethroid similar to naturally occurring pyrethrins. Permethrin lotion 1% is approved by the FDA for the treatment of head lice. Permethrin is safe and effective when used as directed. Permethrin kills live lice but not unhatched eggs. Permethrin may continue to kill newly hatched lice for several days after treatment. A second treatment often is necessary on day 9 to kill any newly hatched lice before they can produce new eggs. Permethrin is approved for use on children 2 months of age and older. \n \n \n \n \n Prescription Medications \n \nThe following medications, in alphabetical order, approved by the U.S. Food and Drug Administration (FDA) for the treatment of head lice are available only by prescription. If crawling lice are still seen after a full course of treatment, contact your health care provider. \n \n - \nBenzyl alcohol lotion, 5%;\n Brand name product: Ulesfia lotion* \nBenzyl alcohol is an aromatic alcohol. Benzyl alcohol lotion, 5% has been approved by the FDA for the treatment of head lice and is considered safe and effective when used as directed. It kills lice but it is not ovicidal(i.e., does not kill lice eggs). A second treatment is needed 9 days after the first treatment to kill any newly hatched lice before they can produce new eggs. Benzyl alcohol lotion is intended for use on persons who are 6 months of age and older and its safety in persons aged more 60 years has not been established. It can be irritating to the skin. \n - \nIvermectin lotion, 0.5%;\n Brand name product: Sklice* \nIvermectin lotion, 0.5% was approved by the FDA in 2012 for treatment of head lice in persons 6 months of age and older. It is not ovicidal, but appears to prevent nymphs (newly hatched lice) from surviving. It is effective in most patients when given as a single application on dry hair without nit combing. It should not be used for retreatment without talking to a healthcare provider. \nGiven as a tablet in mass drug administrations, oral ivermectin has been used extensively and safely for over two decades in many countries to treat filarial worm infections. Although not FDA-approved for the treatment of lice, ivermectin tablets given in a single oral dose of 200 micrograms\/kg repeated in 10 days or 400 micrograms\/kg repeated in 7 days has been shown effective against head lice. It should not be used in children weighing less than 15 kg or in pregnant women. \n - \nSpinosad 0.9% topical suspension;\n Brand name product: Natroba* \nSpinosad is derived from soil bacteria. Spinosad topical suspension, 0.9%, was approved by the FDA in 2011. Since it kills live lice as well as unhatched eggs, retreatment is usually not needed. Nit combing is not required. Spinosad topical suspension is approved for the treatment of children 6 months of age and older. It is safe and effective when used as directed. Repeat treatment should be given only if live (crawling) lice are seen 7 days after the first treatment. \n \n \nFor second\u2013line treatment only: \n \n - \nLindane shampoo 1%;\n Brand name products: None available \nLindane is an organochloride. The American Academy of Pediatrics (AAP) no longer recommends it as a pediculocide. Although lindane shampoo 1% is approved by the FDA for the treatment of head lice, it is not recommended as a first\u2013line treatment. Overuse, misuse, or accidentally swallowing lindane can be toxic to the brain and other parts of the nervous system; its use should be restricted to patients for whom prior treatments have failed or who cannot tolerate other medications that pose less risk. Lindane should not be used to treat premature infants, persons with HIV, a seizure disorder, women who are pregnant or breast\u2013feeding, persons who have very irritated skin or sores where the lindane will be applied, infants, children, the elderly, and persons who weigh less than 110 pounds. Retreatment should be avoided. \n \n \n \n \nWhen treating head lice \n \n - Do not use extra amounts of any lice medication unless instructed to do so by your physician or pharmacist. The drugs used to treat lice are insecticides and can be dangerous if they are misused or overused. \n - All the medications listed above should be kept out of the eyes. If they get onto the eyes, they should be immediately flushed away. \n - Do not treat an infested person more than 2\u20133 times with the same medication if it does not seem to be working. This may be caused by using the medicine incorrectly or by resistance to the medicine. Always seek the advice of your health care provider if this should happen. He\/she may recommend an alternative medication. \n - Do not use different head lice drugs at the same time unless instructed to do so by your physician or pharmacist. \n \n \n \n \n*Use of trade names is for identification purposes only and does not imply endorsement by the Public Health Service or by the U.S. Department of Health and Human Services."} {"_id":"cfa469d7-cb5e-4a5d-a05d-08b1f92c7d5d","text":"Head lice are spread most commonly by direct head-to-head (hair-to-hair) contact.

Once in the environment, it takes 2 to 4 weeks for Toxocara larvae to develop and for the eggs to become infectious. Humans or other animals can be infected by accidentally ingesting Toxocara eggs. For example, humans can become infected if they work with dirt and accidentally ingest dirt containing Toxocara eggs. Although rare, people can be infected by eating undercooked or raw meat from an infected animal such as a lamb or rabbit. Because dogs and cats are frequently found where people live, there may be large numbers of infected eggs in the environment. Once in the body, the Toxocara eggs hatch and roundworm larvae can travel in the bloodstream to different parts of the body, including the liver, heart, lungs, brain, muscles, or eyes. Most infected people do not have any symptoms. However, in some people, the Toxocara larvae can cause damage to these tissues and organs. The symptoms of toxocariasis, the disease caused by these migrating larvae, include fever, coughing, inflammation of the liver, or eye problems.\n \nA U.S. study in 1996 showed that 30% of dogs younger than 6 months deposit Toxocara eggs in their feces; other studies have shown that almost all puppies are born already infected with Toxocara canis. Research also suggests that 25% of all cats are infected with Toxocara cati. Infection rates are higher for dogs and cats that are left outside for more time and allowed to eat other animals. In humans, it has been found that almost 14% of the U.S. population has been infected with Toxocara. Globally, toxocariasis is found in many countries, and prevalence rates can reach as high as 40% or more in parts of the world. There are several factors that have been associated with higher rates of infection with Toxocara. People are more likely to be infected with Toxocara if they own a dog. Children and adolescents under the age of 20 are more likely to test positive for Toxocara infection. This may be because children are more likely to eat dirt and play in outdoor environments, such as sandboxes, where dog and cat feces can be found. This infection is more common in people living in poverty. Geographic location plays a role as well, because Toxocara is more prevalent in hot, humid regions where eggs are kept viable in the soil."} {"_id":"be36997c-5f5e-4358-a3cb-88b2f8a04dda","text":"If you think you or your child may have toxocariasis, you should see your health care provider to discuss the possibility of infection and, if necessary, to be examined.

Raccoons become infected with Baylisascaris in one of two ways:\n \n - Young raccoons become infected by eating eggs during foraging, feeding, and grooming.\n - Adult raccoons acquire the infection by eating rodents, rabbits, and birds infected with the larvae of Baylisascaris.\n \n \nInfected raccoons have been found throughout the United States, mainly in the Midwest, Northeast, Middle Atlantic, and West Coast.\n \nRaccoons are peridomestic animals, which means they live in or around areas where people live. Roundworm eggs are passed in the feces of infected raccoons. Raccoons defecate in communal sites, called latrines. Raccoon latrines are often found at bases of trees, unsealed attics, or on flat surfaces such as logs, tree stumps, rocks, decks, and rooftops. As more raccoons move into populated areas, the number and density of their latrines will increase.\n \nWhile raccoons are the roundworm's primary host, other types of animals can become infected. Birds and small mammals, such as rodents and rabbits, are susceptible to the parasite. Unlike raccoons, these animals sometimes show signs of infection, such as muscle spasms, tremors, and progressive weakness; infection can lead to death. Predator animals, including dogs, may become infected by eating an animal that has been infected with Baylisascaris. In some dogs, Baylisascaris may develop to adult worms and pass eggs in the dogs' feces.\n \nThe worms develop to maturity in the raccoon intestine, where they produce millions of eggs that are passed in the feces. Eggs that are excreted by raccoons are not immediately infectious. These eggs must develop in the environment for 2 to 4 weeks, after which the eggs are able to cause infection. The eggs are resistant to most environmental conditions and with adequate moisture, can survive for years.\n \n \n \n \nHumans become infected by ingesting embryonated (fertile) eggs. Anyone who is exposed to environments where raccoons frequent is potentially at risk. Young children or developmentally disabled persons are at highest risk for infection as they may be more likely to put contaminated fingers, soil, or objects into their mouths.\n \nHunters, trappers, taxidermists, and wildlife handlers may also be at increased risk if they have contact with raccoons or raccoon habitats.\n \nFewer than 25 cases of Baylisascaris disease have been documented in the United States. However, it is possible that some cases are incorrectly diagnosed as other infections or go undiagnosed. Cases that are diagnosed tend to be severe.\n \nCases have been reported in California, Illinois, Louisiana, Massachusetts, Michigan, Minnesota, Missouri, New York, Oregon, and Pennsylvania.

Be sure to tell your health care provider if you have recently been exposed to raccoons or their feces.\n \nDiagnosis is difficult because symptoms depend on the number of infecting larvae and location in the body. Ocular larva migrans, when the larvae migrate to the eye, can cause sensitivity to light, inflammation of the eye, and blindness. Symptoms of visceral larva migrans, when the larvae travel to organs, depend on which organs are affected. For example, an invasion of the liver may cause hepatomegaly (inflammation and enlargement of the liver), while an invasion of the lung may cause pulmonary symptoms such as cough or chest pain. Larvae rarely end up in the nervous system but the most severe cases are neural larva migrans, when the larvae migrate into the brain and cause it to swell (encephalitis).

Wound botulism can be prevented by promptly seeking medical care for infected wounds and by not using injectable street drugs. Most infant botulism cases cannot be prevented because the bacteria that causes this disease is in soil and dust.

The sand fly vectors generally are the most active during twilight, evening, and night-time hours (from dusk to dawn).\n \nIn many geographic areas where leishmaniasis is found in people, infected people are not needed to maintain the transmission cycle of the parasite in nature; infected animals (such as rodents or dogs), along with sand flies, maintain the cycle. However, in some parts of the world, infected people are needed to maintain the cycle; this type of transmission (human\u2014sand fly\u2014human) is called anthroponotic.

Most of the infections worldwide are caused by Wuchereria bancrofti. In Asia, the disease can also be caused by Brugia malayi and Brugia timori.\n \nThe infection spreads from person to person by mosquito bites. The adult worm lives in the human lymph vessels, mates, and produces millions of microscopic worms, also known as microfilariae. Microfilariae circulate in the person's blood and infect the mosquito when it bites a person who is infected. Microfilariae grow and develop in the mosquito. When the mosquito bites another person, the larval worms pass from the mosquito into the human skin, and travel to the lymph vessels. They grow into adult worms, a process that takes 6 months or more. An adult worm lives for about 5\u20137 years. The adult worms mate and release millions of microfilariae into the blood. People with microfilariae in their blood can serve as a source of infection to others.\n \n \n \n \nA wide range of mosquitoes can transmit the parasite, depending on the geographic area. In Africa, the most common vector is Anopheles and in the Americas, it is Culex quinquefasciatus. Aedes and Mansonia can transmit the infection in the Pacific and in Asia.\n \nMany mosquito bites over several months to years are needed to get lymphatic filariasis.

Therefore, if you live in an area where the carrier rodents are known to live, try to keep your home, vacation place, workplace, or campsite clean.\n \nFor more information on how you can prevent rodent infestations, the following information is available on the CDC Rodents site:"} {"_id":"8b5546c4-cbef-4bda-9a46-c03cacd0a3e0","text":"The \"First\"Outbreak\n \nIn May 1993, an outbreak of an unexplained pulmonary illness occurred in the southwestern United States, in an area shared by Arizona, New Mexico, Colorado and Utah known as \"The Four Corners\". A young, physically fit Navajo man suffering from shortness of breath was rushed to a hospital in New Mexico and died very rapidly.\n \n \nWhile reviewing the results of the case, medical personnel discovered that the young man's fianc\u00e9e had died a few days before after showing similar symptoms, a piece of information that proved key to discovering the disease. As Dr. James Cheek of the Indian Health Service (IHS) noted, \"I think if it hadn't been for that initial pair of people that became sick within a week of each other, we never would have discovered the illness at all\".\n \nAn investigation combing the entire Four Corners region was launched by the New Mexico Office of Medical Investigations (OMI) to find any other people who had a similar case history. Within a few hours, Dr. Bruce Tempest of IHS, working with OMI, had located five young, healthy people who had all died after acute respiratory failure.\n \nA series of laboratory tests had failed to identify any of the deaths as caused by a known disease, such as bubonic plague. At this point, the CDC Special Pathogens Branch was notified. CDC, the state health departments of New Mexico, Colorado and Utah, the Indian Health Service, the Navajo Nation, and the University of New Mexico all joined together to confront the outbreak.\n \n \nDuring the next few weeks, as additional cases of the disease were reported in the Four Corners area, physicians and other scientific experts worked intensively to narrow down the list of possible causes. The particular mixture of symptoms and clinical findings pointed researchers away from possible causes, such as exposure to a herbicide or a new type of influenza, and toward some type of virus. Samples of tissue from patients who had gotten the disease were sent to CDC for exhaustive analysis. Virologists at CDC used several tests, including new methods to pinpoint virus genes at the molecular level, and were able to link the pulmonary syndrome with a virus, in particular a previously unknown type of hantavirus.\n Researchers Launch Investigations to Pin Down the Carrier of the New Virus\n \n \nResearchers knew that all other known hantaviruses were transmitted to people by rodents, such as mice and rats. Therefore, an important part of their mission was to trap as many different species of rodents living in the Four Corners region as possible to find the particular type of rodent that carried the virus. From June through mid-August of 1993, all types of rodents were trapped inside and outside homes where people who had hantavirus pulmonary syndrome had lived, as well as in pi\u00f1on groves and summer sheep camps where they had worked. Additional rodents were trapped for comparison in and around nearby households as well. Taking a calculated risk, researchers decided not to wear protective clothing or masks during the trapping process. \"We didn't want to go in wearing respirators, scaring...everybody\", John Sarisky, an Indian Health Service environmental disease specialist said. However, when the almost 1,700 rodents trapped were dissected to prepare samples for analysis at CDC, protective clothing and respirators were worn.\n \nAmong rodents trapped, the deer mouse (Peromyscus maniculatus) was found to be the main host to a previously unknown type of hantavirus. Since the deer mouse often lives near people in rural and semi-rural areas\u2014in barns and outbuildings, woodpiles, and inside people's homes\u2014researchers suspected that the deer mouse might be transmitting the virus to humans. About 30% of the deer mice tested showed evidence of infection with hantavirus. Tests also showed that several other types of rodents were infected, although in lesser numbers.\n \nThe next step was to pin down the connection between the infected deer mice and households where people who had gotten the disease lived. Therefore, investigators launched a case-control investigation. They compared \"case\" households, where people who had gotten the disease lived, with nearby \"control\" households. Control households were similar to those where the case-patients lived, except for one factor: no one in the control households had gotten the disease.\n \nThe results? First, investigators trapped more rodents in case households than in control households, so more rodents may have been living in close contact with people in case households. Second, people in case households were more likely than those in control households to do cleaning around the house or to plant in or hand-plow soil outdoors in fields or gardens. However, it was unclear if the risk for contracting HPS was due to performing these tasks, or with entering closed-up rooms or closets to get tools needed for these tasks.\n \nIn November 1993, the specific hantavirus that caused the Four Corners outbreak was isolated. The Special Pathogens Branch at CDC used tissue from a deer mouse that had been trapped near the New Mexico home of a person who had gotten the disease and grew the virus from it in the laboratory. Shortly afterwards and independently, the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) also grew the virus, from a person in New Mexico who had gotten the disease as well as from a mouse trapped in California.\n \n \nThe new virus was called Muerto Canyon virus \u2014 later changed to Sin Nombre virus (SNV) \u2014 and the new disease caused by the virus was named hantavirus pulmonary syndrome, or HPS.\n \nThe isolation of the virus in a matter of months was remarkable. This success was based on close cooperation of all the agencies and individuals involved in investigating the outbreak, years of basic research on other hantaviruses that had been conducted at CDC and USAMRIID, and on the continuing development of modern molecular virologic tests. To put the rapid isolation of the Sin Nombre virus in perspective, it took several decades for the first hantavirus discovered, the Hantaan virus, to be isolated.\n \n \n HPS Not Really a New Disease\n \nAs part of the effort to locate the source of the virus, researchers located and examined stored samples of lung tissue from people who had died of unexplained lung disease. Some of these samples showed evidence of previous infection with Sin Nombre virus\u2014indicating that the disease had existed before the \"first\" known outbreak\u2014it simply had not been recognized!\n \nOther early cases of HPS have been discovered by examining samples of tissue belonging to people who had died of unexplained adult respiratory distress syndrome. By this method, the earliest known case of HPS that has been confirmed has been the case of a 38-year-old Utah man in 1959.\n \nInterestingly, while HPS was not known to the epidemiologic and medical communities, there is evidence that it was recognized elsewhere. The Navajo Indians, a number of whom contracted HPS during the 1993 outbreak, recognize a similar disease in their medical traditions, and actually associate its occurrence with mice. As strikingly, Navajo medical beliefs concur with public health recommendations for preventing the disease.\n \n \n Why Did the Outbreak Occur in the Four Corners Area?\n \nBut why this sudden cluster of cases? The key answer to this question is that, during this period, there were suddenly many more mice than usual. The Four Corners area had been in a drought for several years. Then, in early 1993, heavy snows and rainfall helped drought-stricken plants and animals to revive and grow in larger-than-usual numbers. The area's deer mice had plenty to eat, and as a result they reproduced so rapidly that there were ten times more mice in May 1993 than there had been in May of 1992. With so many mice, it was more likely that mice and humans would come into contact with one another, and thus more likely that the hantavirus carried by the mice would be transmitted to humans.\n \n \n Person-to-Person Spread of HPS Decided Unlikely\n \n\"Although person-to-person spread [of HPS] has not been documented with any of the other known hantaviruses, we were concerned [during this outbreak] because we were dealing with a new agent\", said Charles Vitek, a CDC medical investigator.\n \nResearchers and clinicians investigating the ongoing outbreak were not the only groups concerned about the disease. Shortly after the first few HPS patients died and it became clear that a new disease was affecting people in the area, and that no one knew how it was transmitted, the news media began extensive reporting on the outbreak. Widespread concern among the public ensued.\n \nUnfortunately, the first victims of the outbreak were Navajo. News reports focused on this fact, and the misperception grew that the unknown disease was somehow linked to Navajos. As a consequence, Navajos found themselves at the center of intense media attention and the objects of the some people's fears.\n \nBy later in the summer of 1993, the media frenzy had quieted somewhat, and the source of the disease was pinpointed. Researchers determined that, like other hantaviruses, the virus that causes HPS is not transmitted from person to person the way other infections, such as the common cold, may be. The exception to this is an outbreak of HPS in Argentina in 1996. Evidence from this outbreak suggests that strains of hantaviruses in South America may be transmissable from person to person.\n \nTo date, no cases of HPS have been reported in the United States in which the virus was transmitted from one person to another. In fact, in a study of health care workers who were exposed to either patients or specimens infected with related types of hantaviruses (which cause a different disease in humans), none of the workers showed evidence of infection or illness.\n \n \n HPS Since the First Outbreak\n \nAfter the initial outbreak, the medical community nationwide was asked to report any cases of illness with symptoms similar to those of HPS that could not be explained by any other cause. As a result, additional cases have been reported.\n \nSince 1993, researchers have discovered that there is not just one hantavirus that causes HPS, but several. In June 1993, a Louisiana bridge inspector who had not traveled to the Four Corners area developed HPS. An investigation was begun. The patient's tissues were tested for the presence of antibodies to hantavirus. The results led to the discovery of another hantavirus, named Bayou virus, which was linked to a carrier, the rice rat (Oryzomys palustris). In late 1993, a 33-year-old Florida man came down with HPS symptoms; he later recovered. This person also had not traveled to the Four Corners area. A similar investigation revealed yet another hantavirus, named the Black Creek Canal virus, and its carrier, the cotton rat (Sigmodon hispidus). Another case occurred in New York. This time, the Sin Nombre-like virus was named New York-1, and the white-footed mouse (Peromyscus leucopus), was implicated as the carrier.\n \nMore recently, cases of HPS stemming from related hantaviruses have been documented in Argentina, Brazil, Canada, Chile, Paraguay, and Uruguay, making HPS a pan-hemispheric disease.\n \n \n References\n \nInformation for this page was developed using the CDC video Preventing Hantavirus Disease and resource articles listed in the bibliography."} {"_id":"9fba7919-c8fb-499a-b49d-90ec221b7272","text":"Q fever can cause acute or chronic illness in humans, who usually acquire infection after contact with infected animals or exposure to contaminated environments. The acute symptoms caused by infection with Coxiella burnetii usually develop within 2-3 weeks of exposure, although as many as half of humans infected withC. burnetii do not show symptoms. \n \nThe following is a list of symptoms commonly seen with acute Q fever. However, it is important to note that the combination of symptoms varies greatly from person to person. \n \n - high fevers (up to 104-105\u00b0F) \n - severe headache \n - general malaise \n - myalgia \n - chills and\/or sweats \n - non-productive cough \n - nausea \n - vomiting \n - diarrhea \n - abdominal pain \n - chest pain \n \n \nAlthough most persons with acute Q fever infection recover, others may experience serious illness with complications that may include pneumonia, granulomatous hepatitis (inflammation of the liver), myocarditis (inflammation of the heart tissue) and central nervous system complications. Pregnant women who are infected may be at risk for pre-term delivery or miscarriage. The estimated case fatality rate (i.e. the proportion of persons who die as a result of their infection) is low, at < 2% of hospitalized patients. Treatment with the correct antibiotic may shorten the course of illness for acute Q fever. \n \nChronic Q fever is a severe disease occurring in <5% of acutely infected patients. It may present soon (within 6 weeks) after an acute infection, or may manifest years later. The three groups at highest risk for chronic Q fever are pregnant women, immunosuppressed persons and patients with a pre-existing heart valve defects. Endocarditis is the major form of chronic disease, comprising 60-70% of all reported cases. The estimated case fatality rate in untreated patients with endocarditis is 25-60%. Patients with endocarditis require early diagnosis and long-term antibiotic treatment (at least 18 months) for a successful outcome. Other forms of chronic Q fever include aortic aneurysms and infections of the bone, liver or reproductive organs, such as the testes in males. \n \nCoxiella burnetii has the ability to persist for long periods of time in the host after infection. Although the majority of people with acute Q fever recover completely, a post-Q fever fatigue syndrome has been reported to occur in 10-25% of some acute patients. This syndrome is characterized by constant or recurring fatigue, night sweats, severe headaches, photophobia (eye sensitivity to light), pain in muscles and joints, mood changes, and difficulty sleeping. \n \n \n Physician Diagnosis \n \nThere are several aspects of Q fever that make it challenging for healthcare providers to diagnose and treat. The symptoms vary from patient to patient and can be difficult to distinguish from other diseases. Treatment is more likely to be effective if started in the first three days of symptoms. Diagnostic tests based on the detection of antibodies will frequently appear negative in the first 7-10 days of illness. For this reason, healthcare providers must use their judgment to treat patients based on clinical suspicion alone. Healthcare providers may find important information in the patient\u2019s history and physical examination that may aid clinical diagnosis. Information such as recent travel to rural or agricultural communities where infected livestock may be present, or employment in high risk occupations such as veterinarians or farmers can be helpful in making the diagnosis. Chronic Q fever is a risk for anyone with a history of acute Q fever illness, particularly those persons with valvular disease, blood vessel abnormalities, immunosuppressed persons, and women who were pregnant when they became infected. \n \nThe healthcare provider should also look at routine blood tests, such as a complete blood cell count or a chemistry panel. Clues such as a prolonged fever with low platelet count, normal leukocyte count, and elevated liver enzymes are suggestive of acute Q fever infection, but may not be present in all patients. After a suspect diagnosis is made based on clinical suspicion and treatment has begun, specialized laboratory testing should be used to confirm the diagnosis of Q fever. \n \nSuspect diagnosis of Q fever is made based on signs and symptoms and a high index of clinical suspicion. Diagnosis can later be confirmed using specialized confirmatory laboratory tests. Treatment should never be delayed pending the receipt of laboratory test results, or be withheld on the basis of an initial negative laboratory result. \n \n \n \n \n Laboratory Confirmation \n \nDuring the acute phase of illness, a sample of whole blood can be tested by polymerase chain reaction (PCR) assay to determine if a patient has Q fever. This method is most sensitive in the first week of illness, and rapidly decreases in sensitivity following the administration of appropriate antibiotics. PCR or immunohistochemistry of biopsy specimens has also been used to diagnose Q fever. These tests may be appropriate for endocarditis patients undergoing valve replacement surgery or patients with hepatitis. Although a positive PCR result is helpful, a negative result does not rule out the diagnosis, and treatment should not be withheld due to a negative result. Culture isolation of C. burnetii is only available at specialized laboratories; routine hospital blood cultures cannot detect the organism. \n \nWhen a person develops Q fever, their immune system produces antibodies to C. burnetii, with detectable antibody titers usually observed by 7-10 days after illness onset. It is important to note that a negative test during the first week of illness does not rule out Q fever as a cause of illness. There are two distinct antigenic phases to which humans develop antibody responses. In acute infection, an antibody response to C. burnetii Phase II antigen is predominant and is higher than Phase I antibody response; the reverse is true in chronic infection which is associated with a rising Phase I IgG titer (according to current U.S. case definitions >1:800) that is often much higher than Phase II IgG. The gold standard serologic test for diagnosis of acute Q fever is the indirect immunofluorescence assay (IFA) using C. burnetii antigen, performed on paired serum samples to demonstrate a significant (four-fold) rise in antibody titers. The first sample should be taken as early in the disease as possible, preferably in the first week of symptoms, and the second sample should be taken 2 to 4 weeks later. In most cases of Q fever, the first IgG IFA titer is typically low, or \u201cnegative,\u201d and the second typically shows a significant (four-fold) increase in IgG antibody levels. IgM antibodies usually rise at the same time as IgG near the end of the first week of illness and remain elevated for months or longer. Also, IgM antibodies are less specific than IgG antibodies and more likely to result in a false positive. For these reasons, physicians should request both Phase I and Phase II IgG and IgM serologic titers for diagnostic confirmation of acute and chronic Q fever. Antibodies to C. burnetii may remain elevated for months or longer after the disease has resolved, or may be detected in persons who were previously exposed to antigenically related organisms. Approximately 3% of currently healthy people in the U.S. general population and up to 20% of people in high-risk professions (veterinarians, ranchers, etc.) have elevated antibody titers due to past exposure to C. burnetii. Therefore, if only one sample is tested it can be difficult to interpret the findings. \n \nPaired samples taken 2-3 weeks apart demonstrating a significant (four-fold) rise in antibody titer provides the best evidence for a correct diagnosis of acute Q fever. Diagnosis of chronic Q fever is confirmed by elevated Phase I IgG antibody (according to current U.S. case definitions >1:800 and higher than Phase II IgG) and an identifiable persistent focus of infection (e.g. endocarditis). Elevated Phase I titers alone do not confirm a chronic Q fever diagnosis and would not warrant treatment in a clinically normal patient. Because chronic Q fever involves lengthy persistence of the organism in the body, the antibody levels are often quite high and you will not see a rising titer between paired serum specimens. \n \nFor more in-depth information about the diagnosis of Q fever, please visit http:\/\/www.bt.cdc.gov\/agent\/qfever\/clinicians\/diagnosis.asp \n \n \n Treatment \n \nDoxycycline is the first line treatment for all adults, and for children with severe illness. Treatment should be initiated immediately whenever Q fever is suspected. \n \nUse of antibiotics other than doxycycline or other tetracyclines is associated with a higher risk of severe illness. Doxycycline is most effective at preventing severe complications from developing if it is started early in the course of disease. Therefore, treatment must be based on clinical suspicion alone and should always begin before laboratory results return. \n \nIf the patient is treated within the first 3 days of the disease, fever generally subsides within 72 hours. In fact, failure to respond to doxycycline suggests that the patient\u2019s condition might not be due to Q fever. Severely ill patients may require longer periods before their fever resolves. Resistance to doxcycline has not been documented. \n \nThere is no role for prophylactic antimicrobial agents in preventing Q fever after a known exposure and prior to symptom onset; attempts at prophylaxis will likely extend the incubation period by several days but will not prevent infection from occurring. \n \nRecommended Dosage for Acute Q fever\n Doxycycline is the first line treatment for children with severe illness of all ages and adults: \n \n - Adults: 100 mg every 12 hours \n - Children under 45 kg (100 lbs): 2.2 mg\/kg body weight given twice a day \n \n \nPatients should be treated for at least 3 days after the fever subsides and until there is evidence of clinical improvement. Standard duration of treatment is 2-3 weeks. \n \nRecommended Dosage for Chronic Q fever \n \n - Adults: Doxycycline 100 mg every 12 hours and hydroxychloroquine 200 mg every 8 hours. \n \n \nStandard duration of treatment is 18 months. \n \n \n Treating children \n \nThe use of doxycycline is recommended to treat Q fever in children of all ages who are hospitalized or are severely ill. Unlike older generations of tetracyclines, doxycycline has not been shown to cause staining of permanent teeth, and most experts consider the benefit of doxycycline in treating Q fever in children younger than 8 years of age with severe illness or who are hospitalized greater than the potential risk of dental staining. Children with mild illness who are less than 8 years of age may be treated with co-trimoxazole, but therapy should be switched to doxycycline if their course of illness worsens. \n \n \n Other Treatments \n \nIn cases of life threatening allergies to doxycycline and in pregnant patients, physicians may need to consider alternate antibiotics. Treatment of pregnant women diagnosed with acute Q fever with once daily co-trimoxazole throughout pregnancy has been shown to significantly decrease the risk of adverse consequences for the fetus."} {"_id":"220ef6b0-3351-4d40-a51c-36496da44502","text":"More detailed information on the diagnosis, management, and treatment of Q fever is available in other sections of this web site and in the materials referenced in the section titled \u201cFurther Reading\u201d. \n How to Contact the Rickettsial Zoonoses Branch at CDC \n \nThe general public and healthcare providers should first call 1-800-CDC-INFO (1-800-232-4636) for questions regarding Q fever.

While a single cause for CFS may yet be identified, another possibility is that CFS has multiple causes. Conditions that have been studied to determine if they cause or trigger the development of CFS include infections, immune disorders, stress, trauma, and toxins.\n Infection\n \nVarious types of infections have been studied to determine if they might cause or trigger CFS:\n \n - Candida albicans, a fungus that causes yeast infections\n - Mycoplasma, a cause of atypical pneumonia\n - Ross River virus, which causes Ross River Fever, a mosquito-borne tropical disease\n \n Could One Type of Infection Lead to CFS?\n \nResearchers from around the world have studied if a single type of infection might be the cause of CFS, analyzed the data, and not yet found any association between CFS and infection. Researchers are still analyzing samples from CFS patients using the latest molecular methods to search for previously unknown infections (pathogen discovery). To date, these studies suggest that no one infection or pathogen causes CFS and that the illness may be triggered by a variety of illnesses or conditions. In fact, infection with Epstein-Barr virus, Ross River virus, and Coxiella burnetti will lead to a post-infective condition that meets the criteria for CFS in approximately 10-12% of cases. People who had severe symptoms when they became infected were more likely than those with mild symptoms to later develop CFS symptoms. The possibility remains that there may be a variety of different ways in which patients can develop CFS.\n Immune System and Allergies\n \nStudies have looked to see if changes in a person's immune system might lead to CFS. The findings have been mixed. Similarities in symptoms from immune responses to infection and CFS lead to hypotheses that CFS may be caused by stress or a viral infection, which may lead to the chronic production of cytokines and then to CFS.\n \nAntibodies against normal parts of the body (auto-antibodies) and immune complexes have been seen in some CFS patients. However, no associated tissue damage typical of autoimmune disease has been described in CFS patients. The opportunistic infections or increased risk for cancer observed in persons with immunodeficiency diseases or in immunosuppressed individuals is also not observed in CFS.\n \nT-cell activation markers have been reported to be different between groups of CFS patients and healthy persons, but not all investigators have consistently observed these differences.\n \nAllergic diseases and secondary illnesses such as sinusitis could be one predisposing factor for CFS, but not all CFS patients have allergies. Many patients do, however, report intolerances for certain substances that may be found in foods or over-the-counter medications, such as alcohol.\n \n \n Hypothalamic-Pituitary Adrenal (HPA) Axis\n \nThe central nervous system plays an important role in CFS. Physical or emotional stress, which is commonly reported as a pre-onset condition in CFS patients, alters the activity of the hypothalamic-pituitary-adrenal axis, or HPA axis, leading to altered release of corticotrophin-releasing hormone (CRH), cortisol, and other hormones. These hormones can influence the immune system and many other body systems.\n \nSome CFS patients produce lower levels of cortisol than do healthy people. Similar hormonal abnormalities have also been observed among CFS patients and in persons with related disorders like fibromyalgia. Cortisol suppresses inflammation and cellular immune activation, and reduced levels might relax constraints on inflammatory processes and immune cell activation. Even though CFS patients had lower levels of cortisol than healthy individuals, their cortisol levels were still within the acceptable range of what is considered normal. Therefore, doctors cannot use cortisol levels as a way to diagnose CFS.\n \n \n Abnormally Low Blood Pressure and Lightheadedness (Neurally Mediated Hypotension)\n \nDisturbances in the autonomic regulation of blood pressure and pulse have been found in CFS patients. This problem with maintaining blood pressure can be diagnosed by using tilt table testing, which involves laying the patient horizontally on a table and then tilting the table upright to 70 degrees for 45 minutes while monitoring blood pressure and heart rate. Persons with neurally mediated hypotension (NMH) or postural orthostatic tachycardia (POTS) will develop lower blood pressure under these conditions, as well as other characteristic symptoms, such as lightheadedness, visual dimming, or a slow response to verbal stimuli. Others may develop an unusually rapid heart rate also associated with the symptoms of the syndrome. Many CFS patients experience lightheadedness or worsened fatigue when they stand for prolonged periods or when in warm places, such as in a hot shower -- all circumstances that are known to trigger NMH or POTS.\n \nNMH and\/or POTS share some of the symptoms of CFS. They should be considered in a CFS patients whose symptoms are worsened with changes in position, after eating, following unusual amounts of or inadequate fluid intake, or increases in activity. Not all patients with CFS will have these conditions, however.\n \n \n Nutritional Deficiency\n \nThere is no published scientific evidence that CFS is caused by a nutritional deficiency. While evidence is currently lacking for nutritional defects in CFS patients, it should also be added that a balanced diet can be favorable to better health in general and would be expected to benefit a person with any chronic illness."} {"_id":"ba8e23b8-6dac-485f-bb50-997a491eeff5","text":"Diagnostic Challenges\n \nFor doctors, diagnosing chronic fatigue syndrome (CFS) can be complicated by a number of factors:\n \n - There's no lab test or biomarker for CFS.\n - Fatigue and other symptoms of CFS are common to many illnesses.\n - For some CFS patients, it may not be obvious to doctors that they are ill.\n - The illness has a pattern of remission and relapse.\n - Symptoms vary from person to person in type, number, and severity.\n \n \nThese factors have contributed to a low diagnosis rate.

Fatigue, for instance, can be a symptom for hundreds of illnesses. Looking closer at the nature of the symptoms though, can help a doctor distinguish CFS from other illnesses.\n Primary Symptoms\n \nAs the name chronic fatigue syndrome suggests, fatigue is one part of this illness. With CFS, however, the fatigue is accompanied by other symptoms. In addition, the fatigue is not the kind you might feel after a particularly busy day or week, after a sleepless night, or after a single stressful event. It's a severe, incapacitating fatigue that isn't improved by bed rest and that is often worsened by physical activity or mental exertion. It's an all-encompassing fatigue that can dramatically reduce a person's activity level and stamina.\n \nPeople with CFS function at a significantly lower level of activity than they were capable of before they became ill. The illness results in a substantial reduction in work-related, personal, social, and educational activities.\n \nThe fatigue of CFS is accompanied by characteristic illness symptoms lasting at least 6 months. These symptoms include:\n \n - increased malaise (extreme exhaustion and sickness) following physical activity or mental exertion\n - problems with sleep\n - difficulties with memory and concentration\n - persistent muscle pain\n - joint pain (without redness or swelling)\n - headache\n - tender lymph nodes in the neck or armpit\n - sore throat\n \n Other Symptoms\n \nThe symptoms listed above are the symptoms used to diagnose CFS. However, many CFS patients and patients in general may experience other symptoms, including:\n \n - brain fog (feeling like you're in a mental fog)\n - difficulty maintaining an upright position, dizziness, balance problems or fainting\n - allergies or sensitivities to foods, odors, chemicals, medications, or noise\n - irritable bowel\n - chills and night sweats\n - visual disturbances (sensitivity to light, blurring, eye pain)\n - depression or mood problems (irritability, mood swings, anxiety, panic attacks)\n \n \nIt's important to tell your health care professional if you're experiencing any of these symptoms. You might have CFS, or you might have another treatable disorder. Only a health care professional can diagnose CFS.\n What's the Clinical Course of CFS?\n \nThe severity of CFS varies from patient to patient. Some people can maintain fairly active lives. For most patients, however, CFS significantly limits their work, school, and family activities for periods of time.\n \nWhile symptoms vary from person to person in number, type, and severity, all CFS patients are limited in what they can do to some degree. CDC studies show that CFS can be as disabling as multiple sclerosis, lupus, rheumatoid arthritis, heart disease, end-stage renal disease, chronic obstructive pulmonary disease (COPD), and similar chronic conditions.\n \nCFS often affects patients in cycles: Patients will have periods of illness followed by periods of relative well-being. For some patients, symptoms may diminish or even go into complete remission; however, they often recur at a later point in time. This pattern of remission and relapse makes CFS especially hard for patients to manage. Patients who are in remission may be tempted to overdo activities when they're feeling better, but this overexertion may actually contribute to a relapse.\n \nThe percentage of CFS patients who recover is unknown, but there is some evidence to indicate that patients benefit when accompanying conditions are identified and treated and when symptoms are managed. High-quality health care is important."} {"_id":"6653cc9b-3616-4ffe-946c-177f5495cd0a","text":"Introduction\n \nManaging chronic fatigue syndrome can be as complex as the illness itself. There is no cure, no prescription drugs have been developed specifically for CFS, and symptoms can vary a lot over time. Thus, people with CFS should closely monitor their health and let their doctor know of any changes; and doctors should regularly monitor their patients' conditions and change treatment strategies as needed.\n \nA team approach that involves doctors and patients is one key to successfully managing CFS. Patients and their doctors can work together to create an individualized treatment program that best meets the needs of the patient with CFS. This program should be based on a combination of therapies that address symptoms, coping techniques, and managing normal daily activities.\n \nCFS affects patients in different ways, and the treatment plan should be tailored to address symptoms that are most disruptive or disabling for each patient. Helping the patient get relief from symptoms is the main goal of treatment. However, expecting a patient to return to usual activities should not be the immediate goal because the physical and mental exertion needed to try to reach that goal may aggravate the illness.\n \nBecause CFS is a complicated illness, its management may require input from a variety of medical professionals. Primary care providers can develop effective treatment plans based on their experience in treating other illnesses. Patients benefit when they can work in collaboration with a team of doctors and other health care professionals, who might also include rehabilitation specialists, mental health professionals, and physical or exercise therapists.\n Difficulties of Living with CFS\n \nLiving with chronic fatigue syndrome can be difficult. Like other debilitating chronic illnesses, CFS can have a devastating impact on patients' daily lives and require them to make major lifestyle changes to adapt to many new limitations.\n \nCommon difficulties for CFS patients include problems coping with:\n \n - the changing and unpredictable symptoms\n - a decrease in stamina that interferes with activities of daily life\n - memory and concentration problems that seriously hurt work or school performance\n - loss of independence, livelihood, and economic security\n - alterations in relationships with partners, family members, and friends\n - worries about raising children\n \n \nFeelings of anger, guilt, anxiety, isolation and abandonment are common in CFS patients. While it's OK to have such feelings, unresolved emotions and stress can make symptoms worse, interfere with prescription drug therapies, and make recovery harder."} {"_id":"e2d4dd42-0b60-4b30-aa3b-1635b4de249d","text":"The first symptoms of Rocky Mountain spotted fever (RMSF) typically begin 2-14 days after the bite of an infected tick. A tick bite is usually painless and about half of the people who develop RMSF do not remember being bitten. The disease frequently begins as a sudden onset of fever and headache and most people visit a healthcare provider during the first few days of symptoms. Because early symptoms may be non-specific, several visits may occur before the diagnosis of RMSF is made and correct treatment begins. The following is a list of symptoms commonly seen with this disease, however, it is important to note that few people with the disease will develop all symptoms, and the number and combination of symptoms varies greatly from person to person. \n \n - Fever \n - Rash (occurs 2-5 days after fever, may be absent in some cases; see below) \n - Headache \n - Nausea \n - Vomiting \n - Abdominal pain (may mimic appendicitis or other causes of acute abdominal pain) \n - Muscle pain \n - Lack of appetite \n - Conjunctival injection (red eyes) \n \n \nRMSF is a serious illness that can be fatal in the first eight days of symptoms if not treated correctly, even in previously healthy people. The progression of the disease varies greatly. Patients who are treated early may recover quickly on outpatient medication, while those who experience a more severe course may require intravenous antibiotics, prolonged hospitalization or intensive care. \n \n \nRash \n \nWhile most people with RMSF (90%) have some type of rash during the course of illness, some people do not develop the rash until late in the disease process, after treatment should have already begun. Approximately 10% of RMSF patients never develop a rash. It is important for physicians to consider RMSF if other signs and symptoms support a diagnosis, even if a rash is not present. \n \nA classic case of RMSF involves a rash that first appears 2-5 days after the onset of fever as small, flat, pink, non-itchy spots (macules) on the wrists, forearms, and ankles and spreads to include the trunk and sometimes the palms and soles. Often the rash varies from this description and people who fail to develop a rash, or develop an atypical rash, are at increased risk of being misdiagnosed. \n \nThe red to purple, spotted (petechial) rash of RMSF is usually not seen until the sixth day or later after onset of symptoms and occurs in 35-60% of patients with the infection. This is a sign of progression to severe disease, and every attempt should be made to begin treatment before petechiae develop. \n \nFigure 1a and 1b: Examples of an early-stage rash in an RMSF patient. \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \nLong-term Health Problems \n \nPatients who had a particularly severe infection requiring prolonged hospitalization may have long-term health problems caused by this disease. Rickettsia rickettsii infects the endothelial cells that line the blood vessels. The damage that occurs in the blood vessels results in a disease process called a \"vasculitis\", and bleeding or clotting in the brain or other vital organs may occur. Loss of fluid from damaged vessels can result in loss of circulation to the extremities and damaged fingers, toes or even limbs may ultimately need to be amputated. Patients who suffer this kind of severe vasculitis in the first two weeks of illness may also be left with permanent long-term health problems such as profound neurological deficits, or damage to internal organs. Those who do not have this kind of vascular damage in the initial stages of the disease typically recover fully within several days to months. \n \n \nInfection in Children \n \nChildren with RMSF infection may experience nausea, vomiting, and loss of appetite. Children are less likely to report a headache, but more likely to develop an early rash than adults. Other frequently observed signs and symptoms in children with RMSF are abdominal pain, altered mental status, and conjunctival injection. Occasionally, symptoms like cough, sore throat, and diarrhea may be seen, and can lead to misdiagnosis. \n \nFor more in-depth information about signs and symptoms of RMSF, please visit http:\/\/www.cdc.gov\/mmwr\/preview\/mmwrhtml\/rr5504a1.htm \n \n \nPhysician Diagnosis \n \nThere are several aspects of RMSF that make it challenging for healthcare providers to diagnose and treat. The symptoms of RMSF vary from patient to patient and can easily resemble other, more common diseases. Treatment for this disease is most effective at preventing death if started in the first five days of symptoms. Diagnostic tests for this disease, especially tests based on the detection of antibodies, will frequently appear negative in the first 7-10 days of illness. Due to the complexities of this disease and the limitations of currently available diagnostic tests, there is no test available at this time that can provide a conclusive result in time to make important decisions about treatment. \n \nFor this reason, healthcare providers must use their judgment to treat patients based on clinical suspicion alone. Healthcare providers may find important information in the patient\u2019s history and physical examination that may aid clinical suspicion. Information such as recent tick bites, exposure to high grass and tick-infested areas, contact with dogs, similar illnesses in family members or pets, or history of recent travel to areas of high incidence can be helpful in making the diagnosis. Also, information about the presence of symptoms such as fever and rash may be helpful. The healthcare provider may also look at routine blood tests, such as a complete blood cell count or a chemistry panel. Clues such as a low platelet count (thrombocytopenia), low sodium levels (hyponatremia), or elevated liver enzyme levels are often helpful predictors of RMSF but may not be present in all patients. After a suspect diagnosis is made on clinical suspicion and treatment has begun, specialized laboratory testing should be used to confirm the diagnosis of RMSF. \n \n \n \n \n \n \n \nLaboratory Confirmation \n \nR. rickettsii infects the endothelial cells that line blood vessels, and does not circulate in large numbers in the blood unless the patient has progressed to a very severe phase of infection. For this reason, blood specimens (whole blood, serum) are not always useful for detection of the organism through polymerase chain reaction (PCR) or culture. If the patient has a rash, PCR or immunohistochemical (IHC) staining can be performed on a skin biopsy taken from the rash site. This test can often deliver a rapid result. These tests have good sensitivity (70%) when applied to tissue specimens collected during the acute phase of illness and before antibiotic treatment has been started, but a negative result should not be used to guide treatment decisions. PCR, culture, and IHC can also be applied to autopsy specimens (liver, spleen, kidney, etc) collected after a patient dies. Culture of R. rickettsii is only available at specialized laboratories; routine hospital blood cultures cannot detect R. rickettsii. \n \nDuring RMSF infection, a patient\u2019s immune system develops antibodies to R. rickettsii, with detectable antibody titers usually observed by 7-10 days after illness onset. It is important to note that antibodies are not detectable in the first week of illness in 85% of patients, and a negative test during this time does not rule out RMSF as a cause of illness. \n \nThe gold standard serologic test for diagnosis of RMSF is the indirect immunofluorescence assay (IFA) with R. rickettsii antigen, performed on two paired serum samples to demonstrate a significant (four-fold) rise in antibody titers. The first sample should be taken as early in the disease as possible, preferably in the first week of symptoms, and the second sample should be taken 2 to 4 weeks later. In most RMSF cases, the first IgG IFA titer is typically low or negative, and the second typically shows a significant (fourfold) increase in IgG antibody levels. IgM antibodies usually rise at the same time as IgG near the end of the first week of illness and remain elevated for months or even years. Also, IgM antibodies are less specific than IgG antibodies and more likely to result in a false positive. For these reasons, physicians requesting IgM serologic titers should also request a concurrent IgG titer. \n \nBoth IgM and IgG levels may remain elevated for months or longer after the disease has resolved, or may be detected in persons who were previously exposed to antigenically related organisms. Up to 10% of currently healthy people in some areas may have elevated antibody titers due to past exposure to R. rickettsii or similar organisms. Therefore, if only one sample is tested it can be difficult to interpret, whereas two paired samples taken weeks apart demonstrating a significant (four-fold) rise in antibody titer provide the best evidence for a correct diagnosis of RMSF. For more in-depth information about testing, please visit http:\/\/www.cdc.gov\/mmwr\/preview\/mmwrhtml\/rr5504a1.htm \n \n \nTreatment \n \nDoxycycline is the first line treatment for adults and children of all ages and should be initiated immediately whenever RMSF is suspected. \n \nUse of antibiotics other than doxycycline is associated with a higher risk of fatal outcome. Treatment is most effective at preventing death if doxycycline is started in the first 5 days of symptoms. Therefore, treatment must be based on clinical suspicion alone and should always begin before laboratory results return or symptoms of severe disease, such as petechiae, develop. \n \nIf the patient is treated within the first 5 days of the disease, fever generally subsides within 24-72 hours. In fact, failure to respond to doxycycline suggests that the patient\u2019s condition might not be RMSF. Severely ill patients may require longer periods before their fever resolves, especially if they have experienced damage to multiple organ systems. Resistance to doxcycline or relapses in symptoms after the completion of the recommended course of treatment have not been documented. \n \nRecommended Dosage\nDoxycycline is the first line treatment for adults and children of all ages: \n \n - Adults: 100 mg every 12 hours \n - Children under 45 kg (100 lbs): 2.2 mg\/kg body weight given twice a day \n \n \nPatients should be treated for at least 3 days after the fever subsides and until there is evidence of clinical improvement. Standard duration of treatment is 7-14 days. \nTreating Children \n \nThe use of doxycycline to treat suspected RMSF in children is standard practice recommended by both CDC and the AAP Committee on Infectious Diseases. Use of antibiotics other than doxycycline increases the risk of patient death. Unlike older tetracyclines, the recommended dose and duration of medication needed to treat RMSF has not been shown to cause staining of permanent teeth, even when five courses are given before the age of eight. Healthcare providers should use doxycycline as the first-line treatment for suspected Rocky Mountain spotted fever in patients of all ages. \nOther Treatments \n \nIn cases of life threatening allergies to doxycycline and in some pregnant patients for whom the clinical course of RMSF appears mild, chloramphenicol may be considered as an alternative antibiotic. Oral forumulations of chloramphenicol are not available in the United States, and use of this drug carries the potential for other adverse risks, such as aplastic anemia and Grey baby syndrome. Furthermore, the risk for fatal outcome is elevated in patients who are treated with chloramphenicol compared to those treated with doxycycline. Other antibiotics, including broad spectrum antibiotics are not effective against R. rickettsii, and the use of sulfa drugs may worsen infection. \nProphylaxis (Preventive Treatment) \n \nAntibiotic treatment following a tick bite is not recommended as a means to prevent RMSF. There is no evidence this practice is effective, and may simply delay onset of disease. Instead, persons who experience a tick bite should be alert for symptoms suggestive of tickborne illness and consult a physician if fever, rash, or other symptoms of concern develop. \n \nFor more in-depth information about treatment, please visit http:\/\/www.cdc.gov\/mmwr\/preview\/mmwrhtml\/rr5504a1.htm \n \n \nOther Considerations \n \nThe clinical presentation for RMSF can also resemble other tickborne diseases, such as ehrlichiosis and anaplasmosis. Similar to RMSF, these infections respond well to treatment with doxycycline. Healthcare providers should order diagnostic tests for additional agents if the clinical history and geographic association warrant.

Each year a few hundred cases are reported to the World Health Organization. Over 95% of the cases of human infection occur in Tanzania, Uganda, Malawi, and Zambia. Animals are the primary reservoir of infection. Cattle have been implicated in the spread of the disease to new areas and in local outbreaks. A wild animal reservoir is thought to be responsible for sporadic transmission to hunters and visitors to game parks. Infection of international travelers is rare, but it occasionally occurs. In the U.S., one case per year, on average, is diagnosed. Most cases of sleeping sickness imported into the U.S. have been in travelers who were on safari in East Africa.\n \nT. b. gambiense (West African sleeping sickness) is found predominantly in central Africa and in limited areas of West Africa. Most of the sleeping sickness in Africa is caused by this form of the parasite. Epidemics of sleeping sickness have been a significant public health problem in the past, but the disease is reasonably well-controlled at present, with 7,000-10,000 cases reported annually in recent years. Over 95% of the cases of human infection are found in Democratic Republic of Congo, Angola, Sudan, Central African Republic, Chad, and northern Uganda. Humans are the important reservoir of infection, although the parasite can sometimes be found in domestic animals (e.g., pigs, dogs, goats).

In general, fascioliasis is more common and widespread in animals than in people. Even so, the number of infected people in the world is thought to exceed 2 million.\n \nFasciola hepatica is found in more than 50 countries, in all continents except Antarctica. It is found in parts of Latin America, the Caribbean, Europe, the Middle East, Africa, Asia, and Oceania. Fasciola gigantica is less widespread. Human cases have been reported in the tropics, in parts of Africa and Asia, and also in Hawaii.\n \nIn some areas where fascioliasis is found, human cases are uncommon (sporadic). In other areas, human fascioliasis is very common (hyperendemic). For example, the areas with the highest known rates of human infection are in the Andean highlands of Bolivia and Peru.\n \nSpecial conditions are needed for fascioliasis to be present in an area, and its geographic distribution is very patchy (focal). The eggs passed in the stool of infected mammals have to develop (mature) in a suitable aquatic snail host to be able to infect another mammalian host. Requirements include sufficient moisture and favorable temperatures (above 50\u00b0F) that allow the development of miracidia, reproduction of snails, and larval development within the snails. These factors also contribute to both the prevalence and level (intensity) of infection. Prevalence is highest in areas where climatic conditions promote development of cercariae.\n \nMore on: Biology\n \nInfective Fasciola larvae (metacercariae) are found in contaminated water, either stuck to (encysted on) water plants or floating in the water, often in marshy areas, ponds, or flooded pastures. People (and animals) typically become infected by eating raw watercress or other contaminated water plants. The plants may be eaten as a snack or in salads or sandwiches. People also can get infected by ingesting contaminated water, such as by drinking it or by eating vegetables that were washed or irrigated with contaminated water. Infection also can result from eating undercooked sheep or goat livers that contain immature forms of the parasite.\n \nThe possibility of becoming infected in the United States should be considered, despite the fact that few locally acquired cases have been documented.

This pathogen is transmitted to humans by the bite of an infected tick. The black-legged tick (Ixodes scapularis) is the vector of A. phagocytophilum in the northeast and upper midwestern United States. The western black-legged tick (Ixodes pacificus) is the primary vector in Northern California. The first symptoms of anaplasmosis typically begin within 1-2 weeks after the bite of an infected tick. A tick bite is usually painless, and some patients who develop anaplasmosis do not remember being bitten. The following is a list of symptoms commonly seen with this disease. However, it is important to note that few people with the disease will develop all symptoms, and the number and combination of symptoms varies greatly from person to person. \n \n - Fever \n - Headache \n - Muscle pain \n - Malaise \n - Chills \n - Nausea \/ Abdominal pain \n - Cough \n - Confusion \n - Rash (rare with anaplasmosis) \n \n \nAnaplasmosis can be a serious illness that can be fatal if not treated correctly, even in previously healthy people. Severe clinical presentations may include difficulty breathing, hemorrhage, renal failure or neurological problems. The estimated case fatality rate (i.e., the proportion of persons who die as a result of their infection) is less than 1%. Patients who are treated early may recover quickly on outpatient medication, while those who experience a more severe course may require intravenous antibiotics, prolonged hospitalization or intensive care. \n \n \n Rash \n \nRash is rarely reported in patients with anaplasmosis and the presence of a rash may signify that the patient has a coinfection with the pathogen that causes Lyme disease or another tickborne disease, such as Rocky Mountain Spotted Fever . \n \n \n Immune-compromised Individuals \n \nThe severity of anaplasmosis may depend in part on the immune status of the patient. Persons with compromised immunity caused by immunosuppressive therapies (e.g., corticosteroids, cancer chemotherapy, or longterm immunosuppressive therapy following organ transplant), HIV infection, or splenectomy appear to develop more severe disease, and case-fatality rates for these individuals are characteristically higher than case-fatality rates reported for the general population. \n \n \n Blood Transfusion and Organ Transplant Risks Associated with Anaplasma species \n \nBecause A. phagocytophilum infects the white blood cells and circulates in the blood stream, this pathogen may pose a risk to be transmitted through blood transfusions. Anaplasma phagocytophilum has been shown to survive for more than a week in refrigerated blood. Several cases of anaplasmosis have been reported associated with the transfusion of packed red blood cells donated from asymptomatic or acutely infected donors. Patients who develop anaplasmosis within a month of receiving a blood transfusion or solid organ transplant should be reported to state health officials for prompt investigation. Use of leukoreduced blood products may theoretically decrease the risk of transfusion-associated transmission of these pathogens. However, the filtration process does not remove all leukocytes or bacteria not associated with leukocytes from leukoreduced blood. Therefore, while this process may reduce the risk of transmission, it does not eliminate it completely. \n \n \n Physician Diagnosis \n \nThere are several aspects of anaplasmosis that make it challenging for healthcare providers to diagnose and treat. The symptoms vary from patient to patient and can be difficult to distinguish from other diseases. Treatment is more likely to be effective if started early in the course of disease. Diagnostic tests based on the detection of antibodies will frequently appear negative in the first 7-10 days of illness. \n \nFor this reason, healthcare providers must use their judgment to treat patients based on clinical suspicion alone. Healthcare providers may find important information in the patient\u2019s history and physical examination that may aid clinical diagnosis. Information such as recent tick bites, exposure to areas where ticks are likely to be found, or history of recent travel to areas where anaplasmosis is endemic can be helpful in making the diagnosis. The healthcare provider should also look at routine blood tests, such as a complete blood cell count or a chemistry panel. Clues such as a low platelet count (thrombocytopenia), low white blood cell count (leukopenia), or elevated liver enzyme levels are helpful predictors of anaplasmosis, but may not be present in all patients. After a suspect diagnosis is made on clinical suspicion and treatment has begun, specialized laboratory testing should be used to confirm the diagnosis of anaplasmosis. \n \n \n \n \n \n \n \n Laboratory Detection \n \nDuring the acute phase of illness, a sample of whole blood can be tested by polymerase chain reaction (PCR) assay to determine if a patient has anaplasmosis. This method is most sensitive in the first week of illness, and rapidly decreases in sensitivity following the administration of appropriate antibiotics. Although a positive PCR result is helpful, a negative result does not completely rule out the diagnosis, and treatment should not be with held due to a negative result. \n \nDuring the first week of illness a microscopic examination of blood smears (known as a peripheral blood smear) may reveal morulae (microcolonies of anaplasma) in the cytoplasm of white blood cells in up to 20% of patients. During A. phagocytophilum infection, morulae are most frequently observed in granulocytes. However, the observance of morulae in a particular cell type cannot conclusively identify the infecting species. Culture isolation of A. phagocytophilum is only available at specialized laboratories; routine hospital blood cultures cannot detect the organism. \n Figure 1: Morulae detected in a granulocyte on a peripheral blood smear, associated with A. phagocytophilum infection. \n \n \n \n \n \n \n \nWhen a person develops anaplasmosis, their immune system produces antibodies to A. phagocytophilum, with detectable antibody titers usually observed by 7-10 days after illness onset. It is important to note that a negative test during the first week of illness does not rule out anaplasmosis as a cause of illness. \n \nThe gold standard serologic test for diagnosis of anaplasmosis is the indirect immunofluorescence assay (IFA) using A. phagocytophilum antigen, performed on paired serum samples to demonstrate a significant (four-fold) rise in antibody titers. The first sample should be taken as early in the disease as possible, preferably in the first week of symptoms, and the second sample should be taken 2 to 4 weeks later. In most cases of anaplasmosis, the first IgG IFA titer is typically low, or \u201cnegative,\u201d and the second typically shows a significant (four-fold) increase in IgG antibody levels. IgM antibodies usually rise at the same time as IgG near the end of the first week of illness and remain elevated for months or longer. Also, IgM antibodies are less specific than IgG antibodies and more likely to result in a false positive. For these reasons, physicians requesting IgM serologic titers should also request a concurrent IgG titer. \n \nSerologic tests based on enzyme immunoassay (EIA) technology are available from some commercial laboratories. However, EIA tests are qualitative rather than quantitative, meaning they only provide a positive\/negative result, and are less useful to measure changes in antibody titers between paired specimens. Furthermore, some EIA assays rely on the evaluation of IgM antibody alone, which may have a higher frequency of false positive results. \n \nAntibodies to A. phagocytophilum may remain elevated for months or longer after the disease has resolved, or may be detected in persons who were previously exposed to antigenically related organisms. Between 5-10% of currently healthy people in some areas may have elevated antibody titers due to past exposure to A. phagocytophilum or similar organisms. Therefore, if only one sample is tested it can be difficult to interpret, while paired samples taken weeks apart demonstrating a significant (four-fold) rise in antibody titer provides the best evidence for a correct diagnosis of anaplasmosis. \n \nFor more in-depth information about the diagnosis of anaplasmosis, please visit http:\/\/www.cdc.gov\/mmwr\/preview\/mmwrhtml\/rr5504a1.htm \n \n \n Treatment \n \nDoxycycline is the first line treatment for adults and children of all ages and should be initiated immediately whenever anaplasmosis is suspected. \n \nUse of antibiotics other than doxycycline or other tetracyclines has been associated with a higher risk of fatal outcome for some rickettsial infections. Doxycycline is most effective at preventing severe complications from developing if it is started early in the course of disease. Therefore, treatment must be based on clinical suspicion alone and should always begin before laboratory results return. \n \nIf the patient is treated within the first 5 days of the disease, fever generally subsides within 24-72 hours. In fact, failure to respond to doxycycline suggests that the patient\u2019s condition might not be due to anaplasmosis. Severely ill patients may require longer periods before their fever resolves. Resistance to doxcycline or relapses in symptoms after the completion of the recommended course have not been documented. \n \nRecommended Dosage\nDoxycycline is the first line treatment for adults and children of all ages: \n \n - Adults: 100 mg every 12 hours \n - Children under 45 kg (100 lbs): 2.2 mg\/kg body weight given twice a day \n \n \nPatients should be treated for at least 3 days after the fever subsides and until there is evidence of clinical improvement. Standard duration of treatment is 7 to 14 days. Some patients may continue to experience headache, weakness and malaise for weeks after adequate treatment. \n Treating children \n \nThe use of doxycycline to treat suspected anaplasmosis in children is standard practice recommended by both CDC and the AAP Committee on Infectious Diseases. Unlike older generations of tetracyclines, the recommended dose and duration of medication needed to treat anaplasmosis has not been shown to cause staining of permanent teeth, even when five courses are given before the age of eight. Healthcare providers should use doxycycline as the first-line treatment for suspected anaplasmosis in patients of all ages. \n Other Treatments \n \nIn cases of life threatening allergies to doxycycline and in some pregnant patients for whom the clinical course of anaplasmosis appears mild, physicians may need to consider alternate antibiotics. Although recommended as a second-line therapeutic alternative to treat Rocky Mountain Spotted Fever , chloramphenicol is not recommended for the treatment of anaplasmosis, as studies have shown a lack of efficacy. Rifampin has been used successfully in several pregnant women with anaplasmosis, and studies suggest that this drug appears effective against Anaplasma species. However, rifampin is not effective in treating RMSF, a disease that may be confused with anaplasmosis. Healthcare providers should be cautious when exploring treatments other than doxycycline, which is highly effective in treating both. Other antibiotics, including broad spectrum antibiotics are not considered highly effective against A. phagocytophilum, and the use of sulfa drugs during acute illness may worsen the severity of infection. \n Prophylaxis (Preventive Treatment) \n \nAntibiotic treatment following a tick bite is not recommended as a means to prevent anaplasmosis. There is no evidence this practice is effective, and this may simply delay onset of disease. Instead, persons who experience a tick bite should be alert for symptoms suggestive of tickborne illness and consult a physician if fever, rash, or other symptoms of concern develop. \n \nFor more in-depth information about treatment, please visit http:\/\/www.cdc.gov\/mmwr\/preview\/mmwrhtml\/rr5504a1.htm \n \n \n Other Considerations \n \nThe clinical presentation for anaplasmosis can resemble other tickborne diseases, such as Rocky Mountain Spotted Fever and ehrlichiosis. Similar to anaplasmosis, these infections respond well to treatment with doxycycline. Healthcare providers should order diagnostic tests for additional agents if the clinical history and geographic association warrant.

The life cycle is completed when rats eat infected snails or slugs and the larvae further mature to become adult worms."} {"_id":"edc6c739-71b6-4574-a3cd-0bad85c4f177","text":"Angiostrongylus cantonensis\n \nAngiostrongylus cantonensis, also known as the rat lungworm, is a parasitic nematode (worm) that is transmitted between rats and mollusks (such as slugs or snails) in its natural life cycle. Other animals that become infected such as freshwater shrimp, land crabs, frogs, and planarians of the genus Platydemus, are transport hosts that are not required for reproduction of the parasite but might be able to transmit infection to humans if eaten raw or undercooked. Humans are accidental hosts who do not transmit infection to others. Most cases of infection are diagnosed in Southeast Asia and the Pacific Basin, but the parasite has also been found in Australia, some areas of Africa, the Caribbean, Hawaii and Louisiana. Outbreaks of human angiostrongyliasis have involved a few to hundreds of persons; over 2,800 cases have been reported in the literature from approximately 30 countries. It is likely that the parasite has been spread by rats transported on ships and by the introduction of mollusks such as the giant African land snail (Achatina fulica). In addition, the semi-slug, Parmarion martensi (native of Southeast Asia)has spread in regions of Hawaii and is found to often be infected with A. cantonensis, and the freshwater snail Pomacea canaliculata (native of South America) has been introduced into Taiwan and China and has been implicated in outbreaks of disease in those countries.\n \nRisk factors for infection with A. cantonensis include the ingestion of raw or undercooked infected snails or slugs; or pieces of snails and slugs accidentally chopped up in vegetables, vegetable juices, or salads; or foods contaminated by the slime of infected snails or slugs. It is possible that ingestion of raw or undercooked transport hosts (freshwater shrimp, land crabs, frogs, etc. ) can result in human infection, though this is less certain. In addition, contamination of the hands during the preparation of uncooked infected snails or slugs could lead to ingestion of the parasite.\n \n \n Angiostrongylus costaricensis\n \nAngiostrongylus costaricensis is a parasitic nematode (worm) that resides in rodents and uses mollusks, such as slugs, as an intermediate host. Rats, such as the cotton rat, transmit the larvae through their feces. Slugs then ingest the larvae. Humans are accidental hosts of the parasite. The parasite is not able to complete its life cycle in humans and eventually dies in the abdomen. Human infection principally occurs in Latin America and the Caribbean, with a few cases suspected in the United States and in the Republic of Congo. The organism is also found in animals in the Southern U.S. (Texas).\n \nRisk factors for infection with A. costaricensis are not well established but are likely to be ingestion of infected slugs or raw vegetables or vegetable juices contaminated with slugs or their slime, which can contain A. costaricensis larvae. The infection of transport hosts, which are not essential to the lifecycle of the parasite, has not been identified and any role in human infection is not known, in contrast to A. cantonensis. Some reports have shown the case rate to be higher in children 6 to 12 years of age, males, and in persons of higher socioeconomic status. There has been one food-related outbreak in Guatemala that affected primarily adults."} {"_id":"93d7ca28-688d-4d2b-8d14-c700eeae2e56","text":"Angiostrongylus cantonensis\n \nDiagnosing A. cantonensis infections can be difficult, in part because there are no readily available blood tests.

However, as of October 2010, all VISA and VRSA isolates have been susceptible to other Food and Drug Administration (FDA)-approved drugs. Persons who develop this type of staph infection may have underlying health conditions (such as diabetes and kidney disease), tubes going into their bodies (such as catheters), previous infections with methicillin-resistant Staphylococcus aureus (MRSA), and recent exposure to vancomycin and other antimicrobial agents. What is Staphylococcus aureus? Staphylococcus aureus is a bacterium commonly found on the skin and in the nose of about 30% of individuals. Most of the time, staph does not cause any harm. These infections can look like pimples, boils, or other skin conditions and most are able to be treated. Sometimes staph bacteria can get into the bloodstream and cause serious infections which can be fatal, including: Bacteremia or sepsis when bacteria spread to the bloodstream usually as a result of using catheters or having surgery. Pneumonia which predominantly affects people with underlying lung disease including those on mechanical ventilators. Endocarditis (infection of the heart valves) which can lead to heart failure. Osteomyelitis (bone infection) which can be caused by staph bacteria traveling in the bloodstream or put there by direct contact such as following trauma (puncture wound of foot or intravenous (IV) drug abuse). Top of page How do VISA and VRSA get their names? Staph bacteria are classified as VISA or VRSA based on laboratory tests. Laboratories perform tests to determine if staph bacteria are resistant to antimicrobial agents that might be used for treatment of infections. For vancomycin and other antimicrobial agents, laboratories determine how much of the agent it requires to inhibit the growth of the organism in a test tube. The result of the test is usually expressed as a minimum inhibitory concentration (MIC) or the minimum amount of antimicrobial agent that inhibits bacterial growth in the test tube. Therefore, staph bacteria are classified as VISA if the MIC for vancomycin is 4-8\u00b5g\/ml, and classified as VRSA if the vancomycin MIC is \u226516\u00b5g\/ml.

It is always better to prevent a disease than to treat it after it occurs. Diseases that used to be common in this country and around the world, including polio, measles, diphtheria, pertussis (whooping cough), rubella (German measles), mumps, tetanus, rotavirus and Haemophilus influenzae type b (Hib) can now be prevented by vaccination. Thanks to a vaccine, one of the most terrible diseases in history \u2013 smallpox \u2013 no longer exists outside the laboratory. Over the years vaccines have prevented countless cases of disease and saved millions of lives. Immunity Protects us From Disease Immunity is the body\u2019s way of preventing disease. Children are born with an immune system composed of cells, glands, organs, and fluids located throughout the body. The immune system recognizes germs that enter the body as \"foreign invaders\u201d (called antigens) and produces proteins called antibodies to fight them. The first time a child is infected with a specific antigen (say measles virus), the immune system produces antibodies designed to fight it. This takes time . . . usually the immune system can\u2019t work fast enough to prevent the antigen from causing disease, so the child still gets sick. However, the immune system \u201cremembers\u201d that antigen. If it ever enters the body again, even after many years, the immune system can produce antibodies fast enough to keep it from causing disease a second time. This protection is called immunity. It would be nice if there were a way to give children immunity to a disease without their having to get sick first. In fact there is: Vaccines contain the same antigens (or parts of antigens) that cause diseases. For example, measles vaccine contains measles virus. But the antigens in vaccines are either killed, or weakened to the point that they don\u2019t cause disease. However, they are strong enough to make the immune system produce antibodies that lead to immunity. In other words, a vaccine is a safer substitute for a child\u2019s first exposure to a disease. The child gets protection without having to get sick. Through vaccination, children can develop immunity without suffering from the actual diseases that vaccines prevent. Top of Page More Facts Newborn babies are immune to many diseases because they have antibodies they got from their mothers. However, this immunity goes away during the first year of life. If an unvaccinated child is exposed to a disease germ, the child's body may not be strong enough to fight the disease. Before vaccines, many children died from diseases that vaccines now prevent, such as whooping cough, measles, and polio. Those same germs exist today, but because babies are protected by vaccines, we don\u2019t see these diseases nearly as often. Immunizing individual children also helps to protect the health of our community, especially those people who cannot be immunized (children who are too young to be vaccinated, or those who can\u2019t receive certain vaccines for medical reasons), and the small proportion of people who don\u2019t respond to a particular vaccine. Vaccine-preventable diseases have a costly impact, resulting in doctor's visits, hospitalizations, and premature deaths. Sick children can also cause parents to lose time from work.

Ehrlichia chaffeensis and Ehrlichia ewingii are transmitted by the lonestar tick in the southeastern and southcentral United States. In addition, a third Ehrlichia species provisionally called Ehrlichia muris-like (EML) has been identified in a small number of patients residing in or traveling to Minnesota and Wisconsin; a tick vector for the EML organism has not yet been established. The symptoms caused by infection with these Ehrlichia species usually develop 1-2 weeks after being bitten by an infected tick. The tick bite is usually painless, and about half of the people who develop ehrlichiosis may not even remember being bitten by a tick. \n \n The following is a list of symptoms commonly seen with this disease, however, it is important to note that the combination of symptoms varies greatly from person to person. \n \n - Fever \n - Headache \n - Chills \n - Malaise \n - Muscle pain \n - Nausea \/ Vomiting \/ Diarrhea \n - Confusion \n - Conjunctival injection (red eyes) \n - Rash (in up to 60% of children, less than 30% of adults) \n \n \nEhrlichiosis is a serious illness that can be fatal if not treated correctly, even in previously healthy people. Severe clinical presentations may include difficulty breathing, or bleeding disorders. The estimated case fatality rate (i.e. the proportion of persons who die as a result of their infection) is 1.8%. Patients who are treated early may recover quickly on outpatient medication, while those who experience a more severe course may require intravenous antibiotics, prolonged hospitalization or intensive care. \n \n \nRash \n \nSkin rash is not considered a common feature of ehrlichiosis, and should not be used to rule in or rule out an infection. Ehrlichia chaffeensis infection can cause a rash in up to 60% of children, but is reported in fewer than 30% of adults. Rash is not commonly reported in patients infected with Ehrlichia ewingii or the Ehrlichia muris-like organism. The rash associated with Ehrlichia chaffeensis infection may range from maculopapular to petechial in nature, and is usually not pruritic (itchy). The rash usually spares the face, but in some cases may spread to the palms and soles. A type of rash called erythroderma may develop in some patients. Erythroderma is a type of rash that resembles a sunburn and consists of widespread reddening of the skin that may peel after several days. Some patients may develop a rash that resembles the rash of Rocky Mountain spotted fever making these two diseases difficult to differentiate on the basis of clinical signs alone. \n \n \nImmune-compromised Individuals \n \nThe severity of ehrlichiosis may depend in part on the immune status of the patient. Persons with compromised immunity caused by immunosuppressive therapies (e.g., corticosteroids , cancer chemotherapy, or longterm immunosuppressive therapy following organ transplant), HIV infection, or splenectomy appear to develop more severe disease, and may also have higher case-fatality rates (i.e. the proportion of patients that die from infection.) \n \n \nBlood Transfusion and Organ Transplant Risks Associated with Ehrlichia species \n \nBecause Ehrlichia organisms infect the white blood cells and circulate in the blood stream, these pathogens may pose a risk to be transmitted through blood transfusions. Ehrlichia chaffeensis has been shown to survive for more than a week in refrigerated blood. Several instances of suspected E. chaffeensis transmission through solid organ transplant have been investigated, although to date no cases have been confirmed that can be attributed to this route of transmission. Patients who develop ehrlichiosis within a month of receiving a blood transfusion or solid organ transplant should be reported to state health officials for prompt investigation. Use of leukoreduced blood products may theoretically decrease the risk of transfusion-associated transmission of these pathogens. However, the filtration process does not remove all leukocytes or bacteria not associated with leukocytes from leukoreduced blood; therefore, this process may not eliminate the risk completely. \n \nFor more in-depth information about signs and symptoms of ehrlichiosis, please visit http:\/\/www.cdc.gov\/mmwr\/preview\/mmwrhtml\/rr5504a1.htm \n \n \nDiagnosis \n \n \n \nThe diagnosis of ehrlichiosis must be made based on clinical signs and symptoms, and can later be confirmed using specialized confirmatory laboratory tests. Treatment should never be delayed pending the receipt of laboratory test results, or be withheld on the basis of an initial negative laboratory result. \nPhysician Diagnosis \n \nThere are several aspects of ehrlichiosis that make it challenging for healthcare providers to diagnose and treat. The symptoms vary from patient to patient and can be difficult to distinguish from other diseases. Treatment is more likely to be effective if started early in the course of disease. Diagnostic tests based on the detection of antibodies will frequently be negative in the first 7-10 days of illness. \n \nFor this reason, healthcare providers must use their judgment to treat patients based on clinical suspicion alone. Healthcare providers may find important information in the patient\u2019s history and physical examination that may aid clinical suspicion. Information such as recent tick bites, exposure to areas where ticks are likely to be found, or history of recent travel to areas where ehrlichiosis is endemic can be helpful in making the diagnosis. The healthcare provider should also look at routine blood tests, such as a complete blood cell count or a chemistry panel. Clues such as a low platelet count (thrombocytopenia), low white blood cell count (leukopenia), or elevated liver enzyme levels are helpful predictors of ehrlichiosis, but may not be present in all patients depending on the course of the disease. After a suspect diagnosis is made on clinical suspicion and treatment has begun, specialized laboratory testing should be used to confirm the diagnosis of ehrlichiosis. \n \n \nLaboratory Detection \n \nDuring the acute phase of illness, a sample of whole blood can be tested by polymerase chain reaction (PCR) assay to determine if a patient has ehrlichiosis. This method is most sensitive in the first week of illness, and quickly decreases in sensitivity following the administration of appropriate antibiotics. Although a positive PCR result is helpful, a negative result does not completely rule out the diagnosis. \n \nDuring the first week of illness a microscopic examination of blood smears (known as a peripheral blood smear) may reveal morulae (microcolonies of ehrlichiae) in the cytoplasm of white blood cells in up to 20% of patients. \n \n \n \n \n \nThe type of blood cell in which morulae are observed may provide insight into the infecting species: E. chaffeensis most commonly infects monocytes, whereas E. ewingii more commonly infect granulocytes. However, the observance of morulae in a particular cell type cannot conclusively identify the infecting species. Culture isolation of Ehrlichia is only available at specialized laboratories; routine hospital blood cultures cannot detect Ehrlichia. \n \nWhen a person develops ehrlichiosis, their immune system produces antibodies to the Ehrlichia, with detectable antibody titers usually observed by 7-10 days after illness onset. It is important to note that antibodies are not detectable in the first week of illness in 85% of patients, and a negative test during this time does not rule out ehrlichiosis as a cause of illness. \n \nThe gold standard serologic test for diagnosis of ehrlichiosis is the indirect immunofluorescence assay (IFA) using E. chaffeensis antigen, performed on paired serum samples to demonstrate a significant (four-fold) rise in antibody titers. The first sample should be taken as early in the disease as possible, preferably in the first week of symptoms, and the second sample should be taken 2 to 4 weeks later. In most cases of ehrlichiosis, the first IgG IFA titer is typically low, or \u201cnegative,\u201d and the second typically shows a significant (four-fold) increase in IgG antibody levels. IgM antibodies usually rise at the same time as IgG near the end of the first week of illness and remain elevated for months or longer. Also, IgM antibodies are less specific than IgG antibodies and more likely to result in a false positive. For these reasons, physicians requesting IgM serologic titers should also request a concurrent IgG titer. \n \nSerologic tests based on enzyme immunoassay (EIA) technology are available from some commercial laboratories. However, EIA tests are qualitative rather than quantitative, meaning they only provide a positive\/negative result, and are less useful to measure changes in antibody titers between paired specimens. Furthermore, some EIA assays rely on the evaluation of IgM antibody alone, which may have a higher frequency of false positive results. \n \nAntibodies to E. chaffeensis may remain elevated for months or longer after the disease has resolved, or may be detected in persons who were previously exposed to antigenically related organisms. Up to 12% of currently healthy people in some areas may have elevated antibody titers due to past exposure to Ehrlichia species or similar organisms. Therefore, if only one sample is tested it can be difficult to interpret, while paired samples taken weeks apart demonstrating a significant (four-fold) rise in antibody titer provides the best evidence for a correct diagnosis of ehrlichiosis. \n \nFor more in-depth information about the diagnosis of ehrlichiosis, please visit http:\/\/www.cdc.gov\/mmwr\/preview\/mmwrhtml\/rr5504a1.htm \n \n \nTreatment \n \nDoxycycline is the first line treatment for adults and children of all ages and should be initiated immediately whenever ehrlichiosis is suspected. \n \nUse of antibiotics other than doxycycline and other tetracyclines is associated with a higher risk of fatal outcome for some rickettsial infections. Doxycycline is most effective at preventing severe complications from developing if it is started early in the course of disease. Therefore, treatment must be based on clinical suspicion alone and should always begin before laboratory results return. \n \nIf the patient is treated within the first 5 days of the disease, fever generally subsides within 24-72 hours. In fact, failure to respond to doxycycline suggests that the patient\u2019s condition might not be due to ehrlichiosis. Severely ill patients may require longer periods before their fever resolves. Resistance to doxcycline or relapses in symptoms after the completion of the recommended course have not been documented. \n \nRecommended Dosage \n \nDoxycycline is the first line treatment for adults and children of all ages: \n \n - Adults: 100 mg every 12 hours \n - Children under 45 kg (100 lbs): 2.2 mg\/kg body weight given twice a day \n \n \nPatients should be treated for at least 3 days after the fever subsides and until there is evidence of clinical improvement. Standard duration of treatment is 7 to 14 days. Some patients may continue to experience headache, weakness and malaise for weeks after adequate treatment. \n \n \nTreating children \n \nThe use of doxycycline to treat suspected ehrlichiosis in children is standard practice recommended by both CDC and the AAP Committee on Infectious Diseases. Unlike older generations of tetracyclines, the recommended dose and duration of medication needed to treat ehrlichiosis has not been shown to cause staining of permanent teeth, even when five courses are given before the age of eight. Healthcare providers should use doxycycline as the first-line treatment for suspected ehrlichiosis in patients of all ages. \n \n \nOther Treatments \n \nIn cases of life threatening allergies to doxycycline and in some pregnant patients for whom the clinical course of ehrlichiosis appears mild, physicians may need to consider alternate antibiotics. Although recommended as a second-line therapeutic alternative to treat Rocky Mountain spotted fever (RMSF), chloramphenicol is not recommended for the treatment of either ehrlichiosis or anaplasmosis, as studies have shown a lack of efficacy. Rifampin appears effective against Ehrlichia in laboratory settings. However, rifampin is not effective in treating RMSF, a disease that may be confused with ehrlichiosis. Healthcare providers should be cautious when exploring treatments other than doxycycline, which is highly effective in treating both. Other antibiotics, including broad spectrum antibiotics are not considered highly effective against ehrlichiosis, and the use of sulfa drugs during acute illness may worsen the severity of infection. \n \n \nProphylaxis (Preventive Treatment) \n \nAntibiotic treatment following a tick bite is not recommended as a means to prevent ehrlichiosis. There is no evidence this practice is effective, and this may simply delay onset of disease. Instead, persons who experience a tick bite should be alert for symptoms suggestive of tickborne illness and consult a physician if fever, rash, or other symptoms of concern develop. \n \nFor more in-depth information about treatment, please visit http:\/\/www.cdc.gov\/mmwr\/preview\/mmwrhtml\/rr5504a1.htm \n \n \nOther Considerations \n \nThe clinical presentation for ehrlichiosis can resemble other tickborne diseases, such as Rocky Mountain spotted fever and anaplasmosis.

There are two kinds of tests that are used to determine if a person has been infected with TB bacteria: the tuberculin skin test and TB blood tests. \n \nA positive TB skin test or TB blood test only tells that a person has been infected with TB bacteria. It does not tell whether the person has latent TB infection (LTBI) or has progressed to TB disease. Other tests, such as a chest x-ray and a sample of sputum, are needed to see whether the person has TB disease. \n \nTuberculin skin test: The TB skin test (also called the Mantoux tuberculin skin test) is performed by injecting a small amount of fluid (called tuberculin) into the skin in the lower part of the arm. A person given the tuberculin skin test must return within 48 to 72 hours to have a trained health care worker look for a reaction on the arm. The health care worker will look for a raised, hard area or swelling, and if present, measure its size using a ruler. Redness by itself is not considered part of the reaction. \n \nThe skin test result depends on the size of the raised, hard area or swelling. It also depends on the person\u2019s risk of being infected with TB bacteria and the progression to TB disease if infected. \n \n - Positive skin test: This \n means the person\u2019s body was infected with TB bacteria. Additional tests are needed to determine if the person has latent TB infection or TB disease. A health care worker will then provide treatment as needed. \n - Negative skin test: This means the person\u2019s body did not react to the test, and that latent TB infection or TB disease is not likely. \n \n \n \n TB blood tests: \n TB blood tests (also called interferon-gamma release assays or IGRAs) measure how the immune system reacts to the bacteria that cause TB. An IGRA measures how strong a person\u2019s immune system reacts to TB bacteria by testing the person\u2019s blood in a laboratory. \n \nTwo IGRAs are approved by the U.S. Food and Drug Administration (FDA) and are available in the United States: \n \n - QuantiFERON\u00ae\u2013TB Gold In-Tube test (QFT-GIT) \n - T-SPOT\u00ae.TB test (T-Spot) \n \n \n - Positive IGRA: This means that the person has been infected with TB bacteria. Additional tests are needed to determine if the person has latent TB infection or TB disease. A health care worker will then provide treatment as needed. \n - Negative IGRA: This means that the person\u2019s blood did not react to the test and that latent TB infection or TB disease is not likely. \n \n \nIGRAs are the preferred method of TB infection testing for the following: \n \n - People who have a difficult time returning for a second appointment to look for a reaction to the TST. \n \n \nThere is no problem with repeated IGRAs. \n \n \n \n Testing for TB in BCG-Vaccinated Persons \n \nMany people born outside of the United States have been BCG-vaccinated. \n \nPeople who have had a previous BCG vaccine may receive a TB skin test. In some people, BCG may cause a positive skin test when they are not infected with TB bacteria. If a TB skin test is positive, additional tests are needed. \n \nIGRAs, unlike the TB skin tests, are not affected by prior BCG vaccination and are not expected to give a false-positive result in people who have received BCG. \n \n Choosing a TB Test \n \nThe person\u2019s health care provider should choose which TB test to use. Factors in selecting which test to use include the reason for testing, test availability, and cost. Generally, it is not recommended to test a person with both a TST and an IGRA. \n \n Diagnosis of Latent TB Infection or TB Disease \n \nIf a person is found to be infected with TB bacteria, other tests are needed to see if the person has TB disease. \n \nTB disease can be diagnosed by medical history, physical examination, chest x-ray, and other laboratory tests. TB disease is treated by taking several drugs as recommended by a health care provider. \n \nIf a person does not have TB disease, but has TB bacteria in the body, then latent TB infection is diagnosed. The decision about treatment for latent TB infection will be based on a person\u2019s chances of developing TB disease. \n \n Diagnosis of TB Disease \n \nPeople suspected of having TB disease should be referred for a medical evaluation, which will include \n \n - Medical history, \n - Physical examination, \n - Test for TB infection (TB skin test or TB blood test), \n - Chest radiograph (X-ray), and \n - Appropriate laboratory tests \n \n \nSee Diagnosis of TB (Fact sheet) for more information about TB diagnosis. \n \n \n Related Links \n \n \n For Patients \n \n \n For Health Care Providers"} {"_id":"3f9d0a8d-83a0-4642-8054-f5699f62765f","text":"Infection Control in Health Care Settings\n \nTuberculosis (TB) transmission has been documented in health care settings where health care workers and patients come in contact with people who have TB disease.\n \nPeople who work or receive care in health care settings are at higher risk for becoming infected with TB; therefore, it is necessary to have a TB infection control plan as part of a general infection control program designed to ensure the following:\n \n - prompt detection of infectious patients,\n - airborne precautions, and\n - treatment of people who have suspected or confirmed TB disease.\n \n \nIn order to be effective, the primary emphasis of a TB infection control program should be on achieving these three goals.\n \nIn all health care settings, particularly those in which people are at high risk for exposure to TB, policies and procedures for TB control should be developed, reviewed periodically, and evaluated for effectiveness to determine the actions necessary to minimize the risk for transmission of TB.\n \nThe TB infection control program should be based on a three-level hierarchy of control measures and include:\n \n - Administrative measures\n - Environmental controls\n - Use of respiratory protective equipment\n \n \nThe first and most important level of the hierarchy, administrative measures, impacts the largest number of people. It is intended primarily to reduce the risk of uninfected people who are exposed to people who have TB disease.\n \nThe second level of the hierarchy is the use of environmental controls to reduce the amount of TB in the air. The first two control levels of the hierarchy also minimize the number of areas in the health care setting where exposure to TB may occur.\n \nThe third level of the hierarchy is the use of respiratory protective equipment in situations that pose a high risk of exposure to TB.

They should ask about administrative and environmental procedures for preventing exposure to TB. Once those procedures are implemented, additional measures could include using personal respiratory protective devices.\n \nTravelers who anticipate possible prolonged exposure to people with TB (for example, those who expect to come in contact routinely with clinic, hospital, prison, or homeless shelter populations) should have a tuberculin skin test (TST) or interferon-gamma release assay (IGRA) test before leaving the United States. If the test reaction is negative, they should have a repeat test 8 to 10 weeks after returning to the United States. Additionally, annual testing may be recommended for those who anticipate repeated or prolonged exposure or an extended stay over a period of years. Because people with HIV infection are more likely to have an impaired response to both the TST and IGRA, travelers who are HIV positive should tell their physicians about their HIV infection status.\n \nMore: Tuberculosis Information for International Travelers\n \n What to Do If You Have Been Exposed to TB\n \nIf you think you have been exposed to someone with TB disease, contact your health care provider or local health department to see if you should be tested for TB.

The bacteria usually attack the lungs, but TB bacteria can attack any part of the body such as the kidney, spine, and brain. If not treated properly, TB disease can be fatal.\n \nNot everyone infected with TB bacteria becomes sick. As a result, two TB-related conditions exist: latent TB infection and TB disease. Both latent TB infection and TB disease can be treated. Learn more about the difference between latent TB infection and TB disease.\n \n Treatment for Latent TB Infection\n \nPeople with latent TB infection have TB bacteria in their bodies, but they are not sick because the bacteria are not active. People with latent TB infection do not have symptoms, and they cannot spread TB bacteria to others. However, if TB bacteria become active in the body and multiply, the person will go from having latent TB infection to being sick with TB disease. For this reason, people with latent TB infection are often prescribed treatment to prevent them from developing TB disease. Treatment of latent TB infection is essential for controlling and eliminating TB in the United States.\n \nBecause there are less bacteria in a person with latent TB infection, treatment is much easier. Four regimens are approved for the treatment of latent TB infection. The medications used to treat latent TB infection include:\n \n - isoniazid (INH)\n - rifampin (RIF)\n - rifapentine (RPT)\n \n \nCertain groups of people (such as people with weakened immune systems) are at very high risk of developing TB disease once infected with TB bacteria. Every effort should be made to begin appropriate treatment and to ensure completion of the entire course of treatment for latent TB infection.\n \nMore: Treatment for Latent TB Infection\n \n Treatment for TB Disease\n \nTB bacteria become active (multiplying in the body) if the immune system can't stop them from growing. When TB bacteria are active, this is called TB disease. TB disease will make a person sick. People with TB disease may spread the bacteria to people with whom they spend many hours.\n \nTB disease can be treated by taking several drugs for 6 to 9 months. There are 10 drugs currently approved by the U.S. Food and Drug Administration (FDA) for treating TB. Of the approved drugs, the first-line anti-TB agents that form the core of treatment regimens include:\n \n - isoniazid (INH)\n - rifampin (RIF)\n - ethambutol (EMB)\n - pyrazinamide (PZA)\n \n \nRegimens for treating TB disease have an initial phase of 2 months, followed by a choice of several options for the continuation phase of either 4 or 7 months (total of 6 to 9 months for treatment). Learn more about the continuation phase of treatment.\n \nIt is very important that people who have TB disease finish the medicine, taking the drugs exactly as prescribed. If they stop taking the drugs too soon, they can become sick again; if they do not take the drugs correctly, the TB bacteria that are still alive may become resistant to those drugs. TB that is resistant to drugs is harder and more expensive to treat.\n \nMore: Treatment for TB Disease\n \n Treatment Completion\n \nTreatment completion is determined by the number of doses ingested over a given period of time. Although basic TB regimens are broadly applicable, there are modifications that should be made under special circumstances (such as people with HIV infection, drug resistance, pregnancy, or treatment of children)."} {"_id":"b07d750e-41f3-46a6-b3b4-3279b34fba48","text":"The Division of Tuberculosis Elimination (DTBE) Laboratory Branch (LB) provides services for the following tests on mycobacterial cultures.

What should a patient do if they think they have vancomycin-resistant enterococci? Recommendations and Guidelines General Information For more images of this bacterium, search the Public Health Image Library What is vancomycin-resistant enterococci? Enteroccocci are bacteria that are normally present in the human intestines and in the female genital tract and are often found in the environment. These bacteria can sometimes cause infections. Vancomycin is an antibiotic that is used to treat some drug-resistant infections caused by enterococci. In some instances, enterococci have become resistant to this drug and thus are called vancomycin-resistant enterococci (VRE). Most VRE infections occur in hospitals. Top of page What types of infections does VRE cause? VRE can live in the human intestines and female genital tract without causing disease (often called colonization). However, sometimes it can cause infections of the urinary tract, the bloodstream, or of wounds associated with catheters or surgical procedures. Top of page Are certain people at risk of getting VRE? The following persons are at increased risk becoming infected with VRE: People who have been previously treated with the antibiotic vancomycin or other antibiotics for long periods of time.

Even tasting very small amounts of undercooked meat during preparation or cooking puts you at risk for infection. Outbreaks occur in settings where multiple people consume the same Trichinella-infected meat.\nWorldwide, an estimated 10,000 cases of trichinellosis occur every year. Several different species of Trichinella can cause human disease; the most common species is Trichinella spiralis, which has a global distribution and is the species most commonly found in pigs. Other Trichinella species are less commonly reported as the cause of human disease and may be found in different parts of the world, usually infecting wild animals.\nIn the United States, trichinellosis cases are reported to CDC much less commonly now than in the past (Figure 1). During the late 1940s, when the U.S. Public Health Service began counting cases of trichinellosis, 400 cases in the United States were recorded each year on average. During 2008-2010, 20 cases were reported to CDC each year on average.

ESS is often discovered during radiological imaging tests for pituitary disorders. ESS occurs n up to 25 percent of the population.An individual with ESS may have no symptoms or may have symptoms resulting from partial or complete loss of pituitary function (including headaches, low sex drive, and impotence).There are two types of ESS: primary and secondary. Primary ESS happens when a small anatomical defect above the pituitary gland allows spinal fluid to partially or completely fill the sella turcica. This causes the gland to flatten out along the interior walls of the sella turcica cavity. Individuals with primary ESS may have high levels of the hormone prolactin, which can interfere with the normal function of the testicles and ovaries. Primary ESS is most common in adults and women, and is often associated with obesity and high blood pressure. In some instances the pituitary gland may be smaller than usual; this may be due to a condition called pseudotumor cerebri (which means \"false brain tumor,\" brought on by high pressure within the skull), In rare instances this high fluid pressure can be associated with drainage of spinal fluid through the nose. Secondary ESS is the result of the pituitary gland regressing within the cavity after an injury, surgery, or radiation therapy. Individuals with secondary ESS can sometimes have symptoms that reflect the loss of pituitary functions, such as the ceasing of menstrual periods, infertility, fatigue, and intolerance to stress and infection.

The result is a single-lobed brain structure and severe skull and facial defects. In most cases of holoprosencephaly, the malformations are so severe that babies die before birth. In less severe cases, babies are born with normal or near-normal brain development and facial deformities that may affect the eyes, nose, and upper lip.\n \nThere are three classifications of holoprosencephaly. Alobar, in which the brain has not divided at all, is usually associated with severe facial deformities. Semilobar, in which the brain's hemispheres have somewhat divided, causes an intermediate form of the disorder. Lobar, in which there is considerable evidence of separate brain hemispheres, is the least severe form. In some cases of lobar holoprosencephaly the baby's brain may be nearly normal.\n \nThe least severe of the facial anomalies is the median cleft lip (premaxillary agenesis). The most severe is cyclopia, an abnormality characterized by a single eye located in the area normally occupied by the root of the nose, and a missing nose or a proboscis (a tubular-shaped nose) located above the eye.

The majority of children with GAN will begin to show symptoms of the disease sometime before five years of age. Signs of GAN usually begin in the peripheral nervous system, which controls movement and sensation in the arms, legs, and other parts of the body. The typical symptoms of GAN are clumsiness and muscle weakness that progresses from a waddling gait to a pronounced difficulty in walking. Additional symptoms include numbness or lack of feeling in the arms and legs, seizures, nystagmus (rapid back and forth movement of the eyes), and impaired cognitive development. A characteristic sign of the disease is dull, tightly curled hair that is markedly different from the parents in color and texture.\n \nResearchers have discovered more than 20 different mutations associated with GAN in a gene, GAN1, which makes a protein called gigaxonin. These mutations disrupt the regulation or production of gigaxonin in the nervous system. As a result, axons, which are the long tails of neurons that allow them to communicate with other nerve cells, swell up with tangled filaments and become abnormally large. Eventually these axons deteriorate and cause problems with movement and sensation since neurons are no longer able to communicate with each other.\n \nDoctors diagnose GAN by using several tests, including one that measures nerve conduction velocity, a brain MRI, and a peripheral nerve biopsy (in which a bit of tissue from a peripheral nerve is removed and examined to look for swollen axons). A definitive diagnosis using genetic testing is available on a research basis only.\n \nGAN is inherited in an autosomal recessive pattern, which means that both parents of a child with GAN have to carry a copy of the mutated gene.

Most doctors agree that TOS is caused by compression of the brachial plexus or subclavian vessels as they pass through narrow passageways leading from the base of the neck to the armpit and arm, but there is considerable disagreement about its diagnosis and treatment. Making the diagnosis of TOS even more difficult is that a number of disorders feature symptoms similar to those of TOS, including rotator cuff injuries, cervical disc disorders, fibromyalgia, multiple sclerosis, complex regional pain syndrome, and tumors of the syrinx or spinal cord. The disorder can sometimes be diagnosed in a physical exam by tenderness in the supraclavicular area, weakness and\/or a \"pins and needles\" feeling when elevating the hands, weakness in the fifth (\"little\") finger, and paleness in the palm of one or both hands when the individual raises them above the shoulders, with the fingers pointing to the ceiling. Symptoms of TOS vary depending on the type. Neurogenic TOS has a characteristic sign, called the Gilliatt-Sumner hand, in which there is severe wasting in the fleshy base of the thumb. Other symptoms include paresthesias (pins and needles sensation or numbness) in the fingers and hand, change in hand color, hand coldness, or dull aching pain in the neck, shoulder, and armpit. Venous TOS features pallor, a weak or absent pulse in the affected arm, which also may be cool to the touch and appear paler than the unaffected arm. Symptoms may include numbness, tingling, aching, swelling of the extremity and fingers, and weakness of the neck or arm..

The incidence of SSPE declined by at least 90 percent in countries that have practiced widespread immunization with measles vaccine. The incidence of SSPE is still high in developing countries such as India and Eastern Europe. There is a higher incidence among males than females (male\/female: 3\/1).

Primary signs of the disorder include difficulty in expressing oneself when speaking, trouble understanding speech, and difficulty with reading and writing. Aphasia is not a disease, but a symptom of brain damage. Although it is primarily seen in individuals who have suffered a stroke, aphasia can also result from a brain tumor, infection, inflammation, head injury, or dementia that affect language-associated regions of the brain. It is estimated that about 1 million people in the United States today suffer from aphasia. The type and severity of language dysfunction depends on the precise location and extent of the damaged brain tissue.\n \nGenerally, aphasia can be divided into four broad categories: (1) Expressive aphasia (also called Broca's aphasia) involves difficulty in conveying thoughts through speech or writing. The person knows what she\/he wants to say, but cannot find the words he needs. (2) Receptive aphasia (Wernicke's aphasia) involves difficulty understanding spoken or written language. The individual hears the voice or sees the print but cannot make sense of the words. (3) Global aphasia results from severe and extensive damage to the language areas of the brain. People lose almost all language function, both comprehension and expression. They cannot speak or understand speech, nor can they read or write.

The procedure is also used to treat essential tremor and dystonia. At present, the procedure is used only for individuals whose symptoms cannot be adequately controlled with medications. However, only individuals who improve to some degree after taking medication for Parkinsons benefit from DBS. A variety of conditions may mimic PD but do not respond to medications or DBS. DBS uses a surgically implanted, battery-operated medical device called an implantable pulse generator (IPG) - similar to a heart pacemaker and approximately the size of a stopwatch to - deliver electrical stimulation to specific areas in the brain that control movement, thus blocking the abnormal nerve signals that cause PD symptoms.\n \nBefore the procedure, a neurosurgeon uses magnetic resonance imaging (MRI) or computed tomography (CT) scanning to identify and locate the exact target within the brain for surgical intervention. Some surgeons may use microelectrode recording - which involves a small wire that monitors the activity of nerve cells in the target area - to more specifically identify the precise brain area that will be stimulated. Generally, these areas are the thalamus, subthalamic nucleus, and globus pallidus. There is a low chance that placement of the stimulator may cause bleeding or infection in the brain.\n \nThe DBS system consists of three components: the lead, the extension, and the IPG. The lead (also called an electrode)a thin, insulated wireis inserted through a small opening in the skull and implanted in the brain. The tip of the electrode is positioned within the specific brain area. \n \nThe extension is an insulated wire that is passed under the skin of the head, neck, and shoulder, connecting the lead to the implantable pulse generator. The IPG (the \"battery pack\") is the third component and is usually implanted under the skin near the collarbone. In some cases it may be implanted lower in the chest or under the skin over the abdomen.\n \nOnce the system is in place, electrical impulses are sent from the IPG up along the extension wire and the lead and into the brain. These impulses block abnormal electrical signals and alleviate PD motor symptoms."} {"_id":"e06ef279-ae99-4ada-b44c-b631b05fface","text":"Unlike previous surgeries for PD, DBS involves minimal permanent surgical changes to the brain.

In some cases, the stimulation itself can suppress dyskinesias without a reduction in medication.

The disease is one of a group of gene-linked disorders known as the leukodystrophies, which affect growth of the myelin sheath -- the fatty covering that wraps around and protects nerve fibers in the brain. The disease is caused by a mutation in the gene that controls the production of a myelin protein called proteolipid protein-1 (PLP1). PMD is inherited as an X-linked recessive trait; the affected individuals are male and the mothers are carriers of the PLP1 mutation. Severity and onset of the disease ranges widely, depending on the type of PLP1 mutation. PMD is one of a spectrum of diseases associated with PLP1, which also includes Spastic Paraplegia Type 2 (SPG2). The PLP1-related disorders span a continuum of neurologic symptoms that range from severe central nervous system involvement (PMD) to progressive weakness and stiffness of the legs (SPG2). There are four general classifications within this spectrum of diseases. In order of severity, they are:\n \n- Connatal PMD, which is the most severe type and involves delayed mental and physical development and severe neurological symptoms; - Classic PMD, in which the early symptoms include muscle weakness, involuntary movements of the eyes (nystagmus), and delays in motor development within the first year of life; - Complicated SPG2, which features motor development issues and brain involvement, and, - Pure SPG2, which includes cases of PMD that do not have neurologic complications.\n \nNoticeable changes in the extent of myelination can be detected by MRI analyses of the brain.

Excess buildup of these fatty materials (oils, waxes, steroids, and other compounds) can cause permanent damage in the cells and tissues in the brain and nervous systems, particularly in nerve cells. There are two distinct groups of the gangliosidoses, which affect males and females equally.\n \nThe GM1 gangliosidoses are caused by a deficiency of the enzyme beta-galactosidase. Signs of early infantile GM1 gangliodisosis (the most severe subtype, with onset shortly after birth) may include neurodegeneration, seizures, liver and spleen enlargement, coarsening of facial features, skeletal irregularities, joint stiffness, distended abdomen, muscle weakness, exaggerated startle response, and problems with gait. About half of affected persons develop cherry-red spots in the eye. Children may be deaf and blind by age 1.Onset of late infantile GM1 gangliosidosisis typically between ages 1 and 3 years. Signs include an inability to control movement, seizures, dementia, and difficulties with speech. Adult GM1 gangliosidosis strikes between ages 3 and 30, with symptoms that include the wasting away of muscles, cloudiness in the corneas, and dystonia (sustained moscle contractions that case twisting and repetitive movements or abnormal postures). Non-cancerous skin blemishes may develop on the lower part of the trunk of the body. Adult GM1 is usually less severe and progresses more slowly than other forms of the disorder.\n \nThe GM2 gangliosidoses include Tay-Sachs disease and its more severe form, called Sandhoff disease, both of whichresult from a deficiency of the enzyme beta-hexosaminidase. Symptoms begin by age 6 months and include progressive mental deterioration, cherry-red spots in the retina, marked startle reflex, and seizures. Children with Tay-Sachs may also have dementia, progressive loss of hearing, some paralysis, and difficulty in swallowing that may require a feeding tube. A rarer form of the disorder, which occurs in individuals in their twenties and early thirties, is characterized by an unsteady gait and progressive neurological deterioration.

As these symptoms become more pronounced, patients may have difficulty walking, talking, or completing other simple tasks. PD usually affects people over the age of 60. Early symptoms of PD are subtle and occur gradually. In some people the disease progresses more quickly than in others. As the disease progresses, the shaking, or tremor, which affects the majority of people with PD may begin to interfere with daily activities. Other symptoms may include depression and other emotional changes; difficulty in swallowing, chewing, and speaking; urinary problems or constipation; skin problems; and sleep disruptions. There are currently no blood or laboratory tests that have been proven to help in diagnosing sporadic PD. Therefore the diagnosis is based on medical history and a neurological examination. The disease can be difficult to diagnose accurately.

Usually, affected individuals are given levodopa combined with carbidopa. Carbidopa delays the conversion of levodopa into dopamine until it reaches the brain. Nerve cells can use levodopa to make dopamine and replenish the brain's dwindling supply. Although levodopa helps at least three-quarters of parkinsonian cases, not all symptoms respond equally to the drug. Bradykinesia and rigidity respond best, while tremor may be only marginally reduced. Problems with balance and other symptoms may not be alleviated at all. Anticholinergics may help control tremor and rigidity. Other drugs, such as bromocriptine, pramipexole, and ropinirole, mimic the role of dopamine in the brain, causing the neurons to react as they would to dopamine. An antiviral drug, amantadine, also appears to reduce symptoms. In May 2006, the FDA approved rasagiline to be used along with levodopa for patients with advanced PD or as a single-drug treatment for early PD.\n \nIn some cases, surgery may be appropriate if the disease doesn't respond to drugs. A therapy called deep brain stimulation (DBS) has now been approved by the U.S. Food and Drug Administration. In DBS, electrodes are implanted into the brain and connected to a small electrical device called a pulse generator that can be externally programmed. DBS can reduce the need for levodopa and related drugs, which in turn decreases the involuntary movements called dyskinesias that are a common side effect of levodopa. It also helps to alleviate fluctuations of symptoms and to reduce tremors, slowness of movements, and gait problems.

Normally, even when relaxed, muscles have a very small amount of contraction that gives them a springy feel and provides some resistance to passive movement. It is not the same as muscle weakness, although the two conditions can co-exist. Muscle tone is regulated by signals that travel from the brain to the nerves and tell the muscles to contract. Hypotonia can happen from damage to the brain, spinal cord, nerves, or muscles. The damage can be the result of trauma, environmental factors, or genetic, muscle, or central nervous system disorders. For example, it can be seen in Down syndrome, muscular dystrophy, cerebral palsy, Prader-Willi syndrome, myotonic dystrophy, and Tay-Sachs disease. Sometimes it may not be possible to find what causes the hypotonia. Infants with hypotonia have a floppy quality or rag doll appearance because their arms and legs hang by their sides and they have little or no head control.

Early symptoms include tremor of the outstretched hands, muscle cramps with exertion, and fasciculations (fleeting muscle twitches visible under the skin). Eventually, individuals develop limb weakness which usually begins in the pelvic or shoulder regions. Weakness of the facial and tongue muscles may occur later in the course of the disease and often leads to dysphagia (difficulty in swallowing), dysarthria (slurring of speech), and recurrent aspiration pneumonia.

The tumors begin in the supporting cells that make up the nerves and the myelin sheath--the thin membrane that envelops and protects the nerves. These disorders cause tumors to grow on nerves and, less frequently, in the brain and spinal cord, and produce other abnormalities such as skin changes and bone deformities. Although many affected persons inherit the disorder, between 30 and 50 percent of new cases arise spontaneously through mutation (change) in an individual's genes. Once this change has taken place, the mutant gene can be passed on to succeeding generations. There are three forms of neurofibromatosis (NF):\n \n- NF1 is the more common type of the disorder. Symptoms of NF1, which may be evident at birth and nearly always by the time the child is 10 years old, may include light brown spots on the skin (\"cafe-au-lait\" spots), two or more growths on the iris of the eye, a tumor on the optic nerve, a larger than normal head circumference, and abnormal development of the spine, a skull bone, or the tibia. - NF2 is less common and is characterized by slow-growing tumors on the vestibular branch of the right and left eighth cranial nerves, which are called vestibular schwannomas or acoustic neuromas.. The tumors press on and damage neighboring nerves and reduce hearing. - The distinctive feature of schwannomatosis is the development of multiple schwannomas (tumors made up of certain cells) everywhere in the body except on the vestibular branch of the 8th cranial nerve. The dominant symptom is pain, which develops as a schwannoma enlarges or compresses nerves or adjacent tissue.

Sometimes surgery is not performed until functional hearing is lost completely. Surgery may result in damage to the facial nerve and some degree of facial paralysis. Focused radiation of vestibular schwannoma carries of a lower risk of facial paralysis than open surgery, but is more effective o shrinking small to moderate tumors than larger tumors. Chemotherapy with a drug that targets the blood vessels of vestibular schwannoma can reduce the size of the tumor and improves hearing, but some tumors do not respond at all and sometimes respond only temporarily.

There are two forms of the syndrome: an early-onset form that is severe, and a late-onset form that has less impact upon neurological function. The early-onset form affects about 20 percent of all babies who have AGS. These infants are born with neurological and liver abnormalities, such as enlargement of the liver and spleen and elevated liver enzymes. Their jittery behavior and poor feeding ability mimic congenital viral infection.\n \nBabies with later-onset AGS begin having symptoms after the first weeks or months of normal development, which appear as a progressive decline in head growth, weak or stiffened muscles (spasticity), and cognitive and developmental delays that range from moderate to severe. Symptoms last for several months, and include irritability, inconsolable crying, intermittent fever, seizures, and loss of developmental skills. Children may also have puffy swelling on the fingers, toes, and ears that resemble chilblains. A number of children have a noticeable startle reaction to sudden noise. For babies with the later-onset form, as symptoms lessen, there is no further worsening of the disease.\n \nAGS is difficult to diagnose since many of the symptoms are similar to those of other disorders. Diagnosis is made based on the clinical symptoms of the disease, as well as characteristic brain abnormalities that can be seen in an MRI brain scan. Cerebrospinal fluid (CSF), taken using a \"spinal tap,\" can also be tested for increased levels of a specific immune system cell (a lymphocyte), which indicates a condition known as chronic lymphocytosis. These cells are normally only elevated during infection, so that lymphocytosis without evidence of infection can be used as an indicator of AGS. CSF may also be tested for elevated levels of a substance known as interferon-gamma, which can also support a diagnosis of AGS.\n \nThe mutations of four different genes are associated with AGS:\n \n- Aicardi-Goutieres syndrome-1 (AGS1) and AGS5 (an autosomal dominant form) are caused by a mutation in the TREX1 gene, - AGS2 is caused by a mutation in the RNASEH2B gene, - AGS3 is caused by a mutation in the RNASEH2C gene, - AGS4 is caused by a mutation in the RNASEH2A gene.\n \nMost cases of AGS are inherited in an autosomal recessive manner, which means that both parents of a child with AGS must carry a single copy of the defective gene responsible for the disease. Parents do not have any symptoms of disease, but with every child they have together, there is a one in four chance that the baby will receive two copies of the defective gene and inherit AGS.\n \nNOTE: AGS is distinct from the similarly named Aicardi syndrome (characterized by absence of a brain structure (corpus callosum), and spinal, skeletal, and eye abnormalities)."} {"_id":"bcc9c71a-5ddc-4695-a1d2-27f840bc4395","text":"Depending upon the severity of symptoms, children may require chest physiotherapy and treatment for respiratory complications.

However, three forms of beta interferon (Avonex, Betaseron, and Rebif) have now been approved by the Food and Drug Administration for treatment of relapsing-remitting MS. Beta interferon has been shown to reduce the number of exacerbations and may slow the progression of physical disability. When attacks do occur, they tend to be shorter and less severe. The FDA also has approved a synthetic form of myelin basic protein, called copolymer I (Copaxone), for the treatment of relapsing-remitting MS. Copolymer I has few side effects, and studies indicate that the agent can reduce the relapse rate by almost one third. Other FDA approved drugs to treat relapsing forms of MS in adults include teriflunomide and dimethyl fumarate. An immunosuppressant treatment, Novantrone (mitoxantrone), isapproved by the FDA for the treatment of advanced or chronic MS. The FDA has also approved dalfampridine (Ampyra) to improve walking in individuals with MS.\n \nOne monoclonal antibody, natalizumab (Tysabri), was shown in clinical trials to significantly reduce the frequency of attacks in people with relapsing forms of MS and was approved for marketing by the U.S. Food and Drug Administration (FDA) in 2004. However, in 2005 the drugs manufacturer voluntarily suspended marketing of the drug after several reports of significant adverse events. In 2006, the FDA again approved sale of the drug for MS but under strict treatment guidelines involving infusion centers where patients can be monitored by specially trained physicians.\n \nWhile steroids do not affect the course of MS over time, they can reduce the duration and severity of attacks in some patients. Spasticity, which can occur either as a sustained stiffness caused by increased muscle tone or as spasms that come and go, is usually treated with muscle relaxants and tranquilizers such as baclofen, tizanidine, diazepam, clonazepam, and dantrolene. Physical therapy and exercise can help preserve remaining function, and patients may find that various aids -- such as foot braces, canes, and walkers -- can help them remain independent and mobile. Avoiding excessive activity and avoiding heat are probably the most important measures patients can take to counter physiological fatigue.

The buildup of storage materials impairs the growth or development of the myelin sheath, the fatty covering that acts as an insulator around nerve fibers. (Myelin, which lends its color to the white matter of the brain, is a complex substance made up of a mixture of fats and proteins.) MLD is one of several lipid storage diseases, which result in the harmful buildup of lipids in brain cells and other cells and tissues in the body. People with lipid storage diseases either do not produce enough of one of the enzymes needed to break down (metabolize) lipids or they produce enzymes that do not work properly. Some leukodystrophies are caused by genetic defects of enzymes that regulate the metabolism of fats needed in myelin synthesis. MLD, which affects males and females, is cause by a deficiency of the enzyme arylsulfatase A. MLD has three characteristic forms: late infantile, juvenile, and adult. Late infantile MLD typically begins between 12 and 20 months following birth. Infants appear normal at first but develop difficulty walking after the first year of life and eventually lose the ability to walk. Other symptoms include muscle wasting and weakness,developmental delays, progressive loss of vision leading to blindness, impaired swallowing, and dementia before age 2.

PBDs are part of a larger group of disorders called the leukodystrophies. The Zellweger spectrum of PBDs include related, but not more severe, disorders referred to as Zellweger syndrome (ZS) and neonatal adrenoleukodystrophy. Collectively, these disorders are caused by inherited defects in any one of 12 genes, called PEX genes, which are required for the normal formation and function of peroxisomes. Peroxisomes are cell structures required for the normal formation and function of the brain, eyes, liver, kidneys, and bone. They contain enzymes that break down toxic substances in the cells, including very long chain fatty acids and phytanic acid (a type of fat found in certain foods), and synthesize certain fatty materials (lipids) that are required for cell function. When peroxisomes are not functioning, there is over-accumulation of very long chain fatty acids and phytanic acid, and a lack of bile acids and plasmalogens--specialized lipids found in cell membranes and the myelin sheaths and encase and protect nerve fibers.. IRD has some residual perixisome function, resulting in less severe disease than in Zellweger syndrome. Symptoms of IRD begin in infancy with retinitis pigmentosa, a visual impairment that often leads to blindness, and hearing problems that usually progress to deafness by early childhood. Other symptoms may include rapid, jerky eye movements (nystagmus); floppy muscle tone (hypotonia) and lack of muscle coordination (ataxia); mental and growth disabilities; abnormal facial features; enlarged liver; and white matter abnormalities of brain myelin.

However, the symptoms of AD gradually lead to behavior and personality changes, a decline in cognitive abilities such as decision-making and language skills, and problems recognizing family and friends. AD ultimately leads to a severe loss of mental function. These losses are related to the worsening breakdown of the connections between certain neurons in the brain and their eventual death. AD is one of a group of disorders called dementias that are characterized by cognitive and behavioral problems. It is the most common cause of dementia among people age 65 and older.\n \nThere are three major hallmarks in the brain that are associated with the disease processes of AD.\n \n- Amyloid plaques, which are made up of fragments of a protein called beta-amyloid peptide mixed with a collection of additional proteins, remnants of neurons, and bits and pieces of other nerve cells. - Neurofibrillary tangles (NFTs), found inside neurons, are abnormal collections of a protein called tau. Normal tau is required for healthy neurons. However, in AD, tau clumps together. As a result, neurons fail to function normally and eventually die. - Loss of connections between neurons responsible for memory and learning.

Neurological diseases that feature cerebellar degeneration include:\n \n- ischemic or hemorrhagic stroke, when there is lack of blood flow or oxygen to the cerebellum - cerebellar cortical atrophy, multisystem atrophy, and olivopontocerebellar degeneration, progressive degenerative disorders in which cerebellar degeneration is a key feature - Friedreichs ataxia, and other spinocerebellar ataxias, which are caused by inherited genetic mutations that result in ongoing loss of neurons in the cerebellum, brain stem, and spinal cord - transmissible spongiform encephalopathies (such as Creutzfeldt-Jakob disease) in which abnormal proteins cause inflammation in the brain, including the cerebellum - multiple sclerosis, in which damage to the insulating membrane (myelin) that wraps around and protects nerve cells can involve the cerebellum Other diseases that can cause cerebellar degeneration include: - chronic alcohol abuse that leads to temporary or permanent cerebellar damage - paraneoplastic disorders, in which a malignancy (cancer) in other parts of the body produces substances that cause immune system cells to attack neurons in the cerebellum Symptoms of cerebellar degeneration: The most characteristic symptom of cerebellar degeneration is a wide-based, unsteady, lurching walk, often accompanied by a back and forth tremor in the trunk of the body.

Congenital myopathy refers to a group of muscle disorders that appear at birth or in infancy. Typically, an infant with a congenital myopathy will be \"floppy,\" have difficulty breathing or feeding, and will lag behind other babies in meeting normal developmental milestones such as turning over or sitting up.\n \nMuscle weakness can occur for many reasons, including a problem with the muscle, a problem with the nerve that stimulates the muscle, or a problem with the brain. Therefore, to diagnose a congenital myopathy, a neurologist will perform a detailed physical exam as well as tests to determine the cause of weakness. If a myopathy is suspected, possible tests include a blood test for a muscle enzyme called creatine kinase, an electromyogram (EMG) to evaluate the electrical activity of the muscle, a muscle biopsy, and genetic testing.\n \nThere are currently seven distinct types of congenital myopathy, with some variation in symptoms, complications, treatment options, and outlook.\n \nNemaline myopathy is the most common congenital myopathy. Infants usually have problems with breathing and feeding. Later, some skeletal problems may arise, such as scoliosis (curvature of the spine). In general, the weakness does not worsen during life.\n \nMyotubular myopathy is rare and only affects boys. Weakness and floppiness are so severe that a mother may notice reduced movements of the baby in her womb during pregnancy. There are usually significant breathing and swallowing difficulties; many children do not survive infancy. Osteopenia (weakening of the bones) is also associated with this disorder.\n \nCentronuclear myopathy is rare and begins in infancy or early childhood with weakness of the arms and legs, droopy eyelids, and problems with eye movements. Weakness often gets worse with time.\n \nCentral core disease varies among children with regard to the severity of problems and the degree of worsening over time. Usually, there is mild floppiness in infancy, delayed milestones, and moderate limb weakness, which do not worsen much over time. Children with central core disease may have life-threatening reactions to general anesthesia. Treatment with the drug salbutamol has been shown to reduce weakness significantly, although it does not cure the disorder.\n \nMulti-minicore disease has several different subtypes. Common to most is severe weakness of the limbs and scoliosis. Often breathing difficulties occur as well. Some children have weakened eye movements.\n \nCongenital fiber-type disproportion myopathy is a rare disorder that begins with floppiness, limb and facial weakness, and breathing problems.\n \nHyaline body myopathy is a disorder characterized by the specific appearance under the microscope of a sample of muscle tissue.

The first symptoms of this disorder include varying degrees of weakness or tingling sensations in the legs. In many instances, the weakness and abnormal sensations spread to the arms and upper body. These symptoms can increase in intensity until the muscles cannot be used at all and the person is almost totally paralyzed. In these cases, the disorder is life-threatening and is considered a medical emergency. The individual is often put on a ventilator to assist with breathing. Most individuals, however, have good recovery from even the most severe cases of Guillain-Barr syndrome (GBS), although some continue to have some degree of weakness. Guillain-Barr syndrome is rare. Usually Guillain-Barr occurs a few days or weeks after the person has had symptoms of a respiratory or gastrointestinal viral infection. Occasionally, surgery will trigger the syndrome. In rare instances, vaccinations may increase the risk of GBS. The disorder can develop over the course of hours or days, or it may take up to 3 to 4 weeks. No one yet knows why Guillain-Barr strikes some people and not others or what sets the disease in motion. What scientists do know is that the body's immune system begins to attack the body itself, causing what is known as an autoimmune disease. Guillain-Barr is called a syndrome rather than a disease because it is not clear that a specific disease-causing agent is involved. Reflexes such as knee jerks are usually lost. Because the signals traveling along the nerve are slower, a nerve conduction velocity (NCV) test can give a doctor clues to aid the diagnosis. The cerebrospinal fluid that bathes the spinal cord and brain contains more protein than usual, so a physician may decide to perform a spinal tap."} {"_id":"d73202f3-e1f1-4dca-bffe-1c32ef41bfc3","text":"There is no known cure for Guillain-Barr syndrome, but therapies can lessen the severity of the illness and accelerate the recovery in most patients.

Plasmapheresis seems to reduce the severity and duration of the Guillain-Barr episode. In high-dose immunoglobulin therapy, doctors give intravenous injections of the proteins that in small quantities, the immune system uses naturally to attack invading organism. Investigators have found that giving high doses of these immunoglobulins, derived from a pool of thousands of normal donors, to Guillain-Barr patients can lessen the immune attack on the nervous system. The most critical part of the treatment for this syndrome consists of keeping the patient's body functioning during recovery of the nervous system.

The damage is the result of the thickening and narrowing (atherosclerosis) of arteries that feed the subcortical areas of the brain. Atherosclerosis (commonly known as \"hardening of the arteries\") is a systemic process that affects blood vessels throughout the body. It begins late in the fourth decade of life and increases in severity with age. As the arteries become more and more narrowed, the blood supplied by those arteries decreases and brain tissue dies. A characteristic pattern of BD-damaged brain tissue can be seen with modern brain imaging techniques such as CT scans or magnetic resonance imaging (MRI). The symptoms associated with BD are related to the disruption of subcortical neural circuits that control what neuroscientists call executive cognitive functioning: short-term memory, organization, mood, the regulation of attention, the ability to act or make decisions, and appropriate behavior. The most characteristic feature of BD is psychomotor slowness - an increase in the length of time it takes, for example, for the fingers to turn the thought of a letter into the shape of a letter on a piece of paper. Other symptoms include forgetfulness (but not as severe as the forgetfulness of Alzheimer's disease), changes in speech, an unsteady gait, clumsiness or frequent falls, changes in personality or mood (most likely in the form of apathy, irritability, and depression), and urinary symptoms that aren't caused by urological disease.

It is caused by mutations in a gene that makes an enzyme called acid alpha-glucosidase (GAA). Normally, the body uses GAA to break down glycogen, a stored form of sugar used for energy. The enzyme performs its function in intracellular compartments called lysosomes. Lysosomes are known to function as cellular clearinghouses; they ingest multiple substances including glycogen, which is converted by the GAA into glucose, a sugar that fuels muscles. In Pompe disease, mutations in the GAA gene reduce or completely eliminate this essential enzyme. Excessive amounts of lysosomal glycogen accumulate everywhere in the body, but the cells of the heart and skeletal muscles are the most seriously affected. Researchers have identified up to 300 different mutations in the GAA gene that cause the symptoms of Pompe disease, which can vary widely in terms of age of onset and severity. The severity of the disease and the age of onset are related to the degree of enzyme deficiency.\n \nEarly onset (or the infantile form) is the result of complete or near complete deficiency of GAA. Symptoms begin in the first months of life, with feeding problems, poor weight gain, muscle weakness, floppiness, and head lag. Respiratory difficulties are often complicated by lung infections. The heart is grossly enlarged. Many infants with Pompe disease also have enlarged tongues. Most babies die from cardiac or respiratory complications before their first birthday.\n \nLate onset (or juvenile\/adult) Pompe disease is the result of a partial deficiency of GAA. The onset can be as early as the first decade of childhood or as late as the sixth decade of adulthood. The primary symptom is muscle weakness progressing to respiratory weakness and death from respiratory failure after a course lasting several years. The heart is usually not involved. A diagnosis of Pompe disease can be confirmed by screening for the common genetic mutations or measuring the level of GAA enzyme activity in a blood sample. Once Pompe disease is diagnosed, testing of all family members and a consultation with a professional geneticist are recommended.

These holes can be seen when brain tissue is viewed under a microscope.\n \nCreutzfeldt-Jakob disease (CJD) is the most well-known of the human TSEs. It is a rare type of dementia that affects about one in every one million people each year. Other human TSEs include kuru, fatal familial insomnia (FFI), and Gerstmann-Straussler-Scheinker disease (GSS). Kuru was identified in people of an isolated tribe in Papua New Guinea and has now almost disappeared. FFI and GSS are extremely rare hereditary diseases, found in just a few families around the world. A new type of CJD, called variant CJD (vCJD), was first described in 1996 and has been found in Great Britain and several other European countries. The initial symptoms of vCJD are different from those of classic CJD and the disorder typically occurs in younger patients. Research suggests that vCJD may have resulted from human consumption of beef from cattle with a TSE disease called bovine spongiform encephalopathy (BSE), also known as \"mad cow disease.\" Other TSEs found in animals include scrapie, which affects sheep and goats; chronic wasting disease, which affects elk and deer; and transmissible mink encephalopathy. In a few rare cases, TSEs have occurred in other mammals such as zoo animals. These cases are probably caused by contaminated feed. CJD and other TSEs also can be transmitted experimentally to mice and other animals in the laboratory.\n \nResearch suggests that TSEs are caused by an abnormal version of a protein called a prion (prion is short for proteinaceous infectious particle). Prion proteins occur in both a normal form, which is a harmless protein found in the body's cells, and in an infectious form, which causes disease. The harmless and infectious forms of the prion protein are nearly identical, but the infectious form takes on a different folded shape from the normal protein.\n \nHuman TSEs can occur three ways: sporadically; as hereditary diseases; or through transmission from infected individuals. Sporadic TSEs may develop because some of a person's normal prions spontaneously change into the infectious form of the protein and then alter the prions in other cells in a chain reaction. Inherited cases arise from a change, or mutation, in the prion protein gene that causes the prions to be shaped in an abnormal way. This genetic change may be transmitted to an individual's offspring. Transmission of TSEs from infected individuals is relatively rare. TSEs cannot be transmitted through the air or through touching or most other forms of casual contact. However, they may be transmitted through contact with infected tissue, body fluids, or contaminated medical instruments. Normal sterilization procedures such as boiling or irradiating materials do not prevent transmission of TSEs.\n \nSymptoms of TSEs vary, but they commonly include personality changes, psychiatric problems such as depression, lack of coordination, and\/or an unsteady gait.

Nerve cells (neurons) can also be damaged. Certain areas of the brain are particularly susceptible to myelinolysis, especially the part of the brain stem called the pons. Some individuals will also have damage in other areas of the brain, which is called extrapontine myelinolysis (EPM). Experts estimate that 10 percent of those with CPM will also have areas of EPM.\n \nThe initial symptoms of myelinolysis, which begin to appear 2 to 3 days after hyponatremia is corrected, include a depressed level of awareness, difficulty speaking (dysarthria or mutism), and difficulty swallowing (dysphagia). Additional symptoms often arise over the next 1-2 weeks, including impaired thinking, weakness or paralysis in the arms and legs, stiffness, impaired sensation, and difficulty with coordination. At its most severe, myelinolysis can lead to coma, locked-in syndrome (which is the complete paralysis of all of the voluntary muscles in the body except for those that control the eyes), and death.\n \nAlthough many affected people improve over weeks to months, some have permanent disability.

Most involve the activities of neurotransmitters. Neurotransmitters are chemicals that allow neurons to relay information from one cell to the next. For neurotransmitters to be effective, the nerve cell must release the neurotransmitter properly, and the muscle cell must be able to detect the neurotransmitter and respond to its signal properly.\n \nThe most common type of myasthenia, myasthenia gravis, is caused by an abnormal immune response in which antibodies block the ability of the muscle to detect the neurotransmitter. Congenital myasthenia, however, differs from myasthenia gravis because the disrupted communication isn't caused by antibodies, but by genetic defects.\n \nThere are several different subtypes of congenital myasthenia, each the result of a specific genetic mutation. Since all types of myasthenia are due to the inability of nerves to trigger muscle activity, they all involve weakness, although there is some variability in the specific muscles affected.\n \nSymptoms of congenital myasthenia usually appear in the first few years of childhood, but may not be noticeable until much later, occasionally remaining unrecognized until adulthood. If the symptoms begin in infancy, they usually appear as \"floppiness\" and a failure to meet developmental milestones, such as rolling over or sitting up. Some infants may also have episodes of choking or pauses in breathing. If the symptoms begin in toddlers or preschool children, they appear as weakness during physical activities or an inability to perform age-appropriate actions, such as running or climbing. In addition, if eye muscles are involved, children may have droopy eyelids, \"lazy eye,\" or double vision. If mouth or throat muscles are involved, children may have difficulty speaking or swallowing. An important characteristic of myasthenia is that the weakness worsens during continuous activity, with strength returning, at least partially, after resting.\n \nCongenital myasthenia is an inherited (genetic) disorder. All but one known subtype are recessive disorders, which means that a child will have to have two copies of the abnormal gene (one from each parent) in order to develop the disease.

The symptoms of ADEM appear rapidly, beginning with encephalitis-like symptoms such as fever, fatigue, headache, nausea and vomiting, and in the most severe cases, seizures and coma. ADEM typically damages white matter (brain tissue that takes its name from the white color of myelin), leading to neurological symptoms such as visual loss (due to inflammation of the optic nerve)in one or both eyes, weakness even to the point of paralysis, and difficulty coordinating voluntary muscle movements (such as those used in walking). ADEM is sometimes misdiagnosed as a severe first attack of multiple sclerosis (MS), since the symptoms and the appearance of the white matter injury on brain imaging may be similar. However, ADEM has several features which differentiate it from MS. First, unlike MS patients, persons with ADEM will have rapid onset of fever, a history of recent infection or immunization, and some degree of impairment of consciousness, perhaps even coma; these features are not typically seen in MS.

Other NINDS-funded research is investigating the hypothesis that POTS is a syndrome of different subtypes, with different underlying mechanisms. Additionally, the NINDS funds the Autonomic Rare Diseases Consortium to further understand disorders such as orthostatic hypotension and hopefully alter the course of disease."} {"_id":"6454d9ff-eb40-4361-9422-1f1d5328ad4f","text":"Rasmussens encephalitis is a rare, chronic inflammatory neurological disease that usually affects only one hemisphere of the brain.

SD is characterized by rapid, irregular, and aimless involuntary movements of the arms and legs, trunk, and facial muscles. It affects girls more often than boys and typically occurs between 5 and 15 years of age. Some children will have a sore throat several weeks before the symptoms begin, but the disorder can also strike up to 6 months after the fever or infection has cleared. Symptoms can appear gradually or all at once, and also may include uncoordinated movements, muscular weakness, stumbling and falling, slurred speech, difficulty concentrating and writing, and emotional instability. The symptoms of SD can vary from a halting gait and slight grimacing to involuntary movements that are frequent and severe enough to be incapacitating. The random, writhing movements of chorea are caused by an auto-immune reaction to the bacterium that interferes with the normal function of a part of the brain (the basal ganglia) that controls motor movements. Due to better sanitary conditions and the use of antibiotics to treat streptococcal infections, rheumatic fever, and consequently SD, are rare in North America and Europe.

In people who have a lactase deficiency, the small intestine produces low levels of lactase and cannot digest much lactose. - Lactose malabsorption. Lactase deficiency may cause lactose malabsorption. In lactose malabsorption, undigested lactose passes to the colon. The colon, part of the large intestine, absorbs water from stool and changes it from a liquid to a solid form. In the colon, bacteria break down undigested lactose and create fluid and gas. Not all people with lactase deficiency and lactose malabsorption have digestive symptoms.\n \nPeople have lactose intolerance when lactase deficiency and lactose malabsorption cause digestive symptoms. Most people with lactose intolerance can eat or drink some amount of lactose without having digestive symptoms. Individuals vary in the amount of lactose they can tolerate.\n \nPeople sometimes confuse lactose intolerance with a milk allergy. While lactose intolerance is a digestive system disorder, a milk allergy is a reaction by the bodys immune system to one or more milk proteins. An allergic reaction to milk can be life threatening even if the person eats or drinks only a small amount of milk or milk product. A milk allergy most commonly occurs in the first year of life, while lactose intolerance occurs more often during adolescence or adulthood.1,2\n \n\n \nFour Types of Lactase Deficiency Four types of lactase deficiency may lead to lactose intolerance: - Primary lactase deficiency, also called lactase nonpersistence, is the most common type of lactase deficiency. In people with this condition, lactase production declines over time. This decline often begins at about age 2; however, the decline may begin later. Children who have lactase deficiency may not experience symptoms of lactose intolerance until late adolescence or adulthood. Researchers have discovered that some people inherit genes from their parents that may cause a primary lactase deficiency. - Secondary lactase deficiency results from injury to the small intestine. Infection, diseases, or other problems may injure the small intestine. Treating the underlying cause usually improves the lactose tolerance. - Developmental lactase deficiency may occur in infants born prematurely. This condition usually lasts for only a short time after they are born. - Congenital lactase deficiency is an extremely rare disorder in which the small intestine produces little or no lactase enzyme from birth. Genes inherited from parents cause this disorder."} {"_id":"98853848-3b92-4f0d-b696-fe060417354a","text":"Four types of lactase deficiency may lead to lactose intolerance:\n \n- Primary lactase deficiency, also called lactase nonpersistence, is the most common type of lactase deficiency.

A health care provider will take a medical, family, and diet history to help diagnose lactose intolerance. During this discussion, the health care provider will review a patients symptoms. However, basing a diagnosis on symptoms alone may be misleading because digestive symptoms can occur for many reasons other than lactose intolerance. For example, other conditions such as irritable bowel syndrome, celiac disease, inflammatory bowel disease, or small bowel bacterial overgrowth can cause digestive symptoms.\n \nPhysical exam. A physical exam may help diagnose lactose intolerance or rule out other conditions that cause digestive symptoms. During a physical exam, a health care provider usually\n \n- checks for abdominal bloating - uses a stethoscope to listen to sounds within the abdomen - taps on the abdomen to check for tenderness or pain\n \nA health care provider may recommend eliminating all milk and milk products from a persons diet for a short time to see if the symptoms resolve. Symptoms that go away when a person eliminates lactose from his or her diet may confirm the diagnosis of lactose intolerance.\n \nMedical tests. A health care provider may order special tests to provide more information. Health care providers commonly use two tests to measure how well a person digests lactose:\n \n- Hydrogen breath test. This test measures the amount of hydrogen in a persons breath. Normally, only a small amount of hydrogen is detectable in the breath when a person eats or drinks and digests lactose. However, undigested lactose produces high levels of hydrogen. For this test, the patient drinks a beverage that contains a known amount of lactose. A health care provider asks the patient to breathe into a balloon-type container that measures breath hydrogen level. In most cases, a health care provider performs this test at a hospital, on an outpatient basis. Smoking and some foods and medications may affect the accuracy of the results. A health care provider will tell the patient what foods or medications to avoid before the test. - Stool acidity test. Undigested lactose creates lactic acid and other fatty acids that a stool acidity test can detect in a stool sample. Health care providers sometimes use this test to check acidity in the stools of infants and young children. A child may also have glucose in his or her stool as a result of undigested lactose. The health care provider will give the childs parent or caretaker a container for collecting the stool specimen.

Gradually introducing small amounts of milk or milk products may help some people adapt to them with fewer symptoms. Often, people can better tolerate milk or milk products by having them with meals, such as having milk with cereal or having cheese with crackers. People with lactose intolerance are generally more likely to tolerate hard cheeses, such as cheddar or Swiss, than a glass of milk. A 1.5ounce serving of low-fat hard cheese has less than 1 gram of lactose, while a 1-cup serving of low-fat milk has about 11 to 13 grams of lactose.2\n \nHowever, people with lactose intolerance are also more likely to tolerate yogurt than milk, even though yogurt and milk have similar amounts of lactose.2\n \nLactose-free and lactose-reduced milk and milk products. Lactose-free and lactose-reduced milk and milk products are available at most supermarkets and are identical nutritionally to regular milk and milk products. Manufacturers treat lactose-free milk with the lactase enzyme. This enzyme breaks down the lactose in the milk. Lactose-free milk remains fresh for about the same length of time or, if it is ultra-pasteurized, longer than regular milk. Lactose-free milk may have a slightly sweeter taste than regular milk.\n \nLactase products. People can use lactase tablets and drops when they eat or drink milk products. The lactase enzyme digests the lactose in the food and therefore reduces the chances of developing digestive symptoms. People should check with a health care provider before using these products because some groups, such as young children and pregnant and breastfeeding women, may not be able to use them."} {"_id":"e4380939-79e4-4a3e-ad02-f5c80c2d67eb","text":"- Lactose is a sugar found in milk and milk products. - Lactose intolerance is a condition in which people have digestive symptomssuch as bloating, diarrhea, and gasafter eating or drinking milk or milk products. - A health care provider makes a diagnosis of lactose intolerance based on medical, family, and diet history, including a review of symptoms; a physical exam; and medical tests. - Basing a diagnosis on symptoms alone may be misleading because digestive symptoms can occur for many reasons other than lactose intolerance. - Most people with lactose intolerance can tolerate some amount of lactose in their diet and do not need to avoid milk or milk products completely.

For the test, you will lie on a table while the doctor inserts a flexible tube into your anus. A small camera on the tube sends a video image of the intestinal lining to a computer screen. The doctor can see inflammation, ulcers, or bleeding. The doctor may also perform a biopsy. The doctor will look at the tissue with a microscope to confirm the diagnosis of Crohns disease. In most cases, youll be given a light sedative, and possibly pain medicine, to help you relax. You will not feel the biopsy. Cramping or bloating may occur during the first hour after the test. Driving is not permitted for 24 hours after the test to allow the sedative time to wear off. Before the appointment, you should make plans for a ride home.

You will not feel the biopsy. You can usually go back to your normal diet after the test, though you may have cramping or bloating during the first hour after the test. - Computerized tomography (CT) scan. A CT scan uses x rays and computers to create images of the inside of the body. For the test, you will lie on a table that slides into a tunnel-shaped device where the x rays are taken. The technician may give you a solution to drink and an injection of a special dye through a needle inserted into an arm vein. You will not need a sedative for the test. CT scans can be used to help diagnose Crohn's disease. - Upper GI series (x rays). An upper GI series may be done to look at the small intestine. No eating or drinking is allowed for 8 hours before the procedure. You will not need a sedative for the test. During the procedure, you will stand or sit in front of an x-ray machine and drink barium, a chalky liquid. The barium coats the small intestine, making signs of the disease show up more clearly on x rays. After the test, you may go back to your normal diet, though you may have nausea or bloating for a short time. Traces of barium in the GI tract cause stools to be white or light colored for a few days after the test. - Lower GI series (x rays). A lower GI series may be done to look at the large intestine. The health care provider will give you written bowel prep instructions to follow at home before the test. You will be asked to follow a clear liquid diet for 1 to 3 days before the test. A laxative or enema is usually used the evening before a lower GI series. Enemas are sometimes repeated the morning of the test.

A surgeon performs the procedure in a hospital, where you will receive medicine to make you sleep during the surgery.\n \nOne or more of the following surgeries may be needed:\n \n- Intestinal resection. The surgeon removes the diseased section of intestine and puts the ends of the intestine back together. - Proctocolectomy. Proctocolectomy is surgery to remove the rectum and part or all of the colon. An ileostomy is performed with a proctocolectomy. - Ileostomy. Ileostomy is an operation to create an openingcalled a stomafor the stool to exit the body when the ends of the intestine cannot be put back together. To create a stoma, an end of the intestine is brought out through a small opening made on the lower right part of the abdomen near the beltline. The stoma is about the size of a quarter. An ostomy pouch is worn outside the body over the stoma to collect waste, and it is emptied several times a day. Your health care provider may refer you to an ostomy nursea specialist who cares for people with an ostomy pouch.\n \nSurgery usually does not cure Crohn's disease forever.

Factors that can increase this force include higher blood volume due to extra fluid in the blood and blood vessels that are narrow, stiff, or clogged.\n \nBlood pressure test results are written with two numbers separated by a slash. For example, a health care provider will write a blood pressure result as 120\/80. A health care provider will say this blood pressure result as 120 over 80. The top number is called the systolic pressure and represents the pressure as the heart beats and pushes blood through the blood vessels. The bottom number is called the diastolic pressure and represents the pressure as blood vessels relax between heartbeats.\n \nMost people without chronic health conditions have a normal blood pressure if it stays below 120\/80.

Every day, the two kidneys filter about 120 to 150 quarts of blood to produce about 1 to 2 quarts of urine, composed of wastes and extra fluid. The urine flows from the kidneys to the bladder through tubes called ureters. The bladder stores urine. When the bladder empties, urine flows out of the body through a tube called the urethra, located at the bottom of the bladder. In men the urethra is long, while in women it is short.\n \nKidneys work at the microscopic level. The kidney is not one large filter. Each kidney is made up of about a million filtering units called nephrons. Each nephron filters a small amount of blood. The nephron includes a filter, called the glomerulus, and a tubule. The nephrons work through a two-step process. The glomerulus lets fluid and waste products pass through it; however, it prevents blood cells and large molecules, mostly proteins, from passing.

A dipstick test performed on a urine sample can detect the presence of albumin in the urine. Albumin is a protein in the blood that can pass into the urine when the kidneys are damaged. A patient collects the urine sample in a special container in a health care providers office or a commercial facility. The office or facility tests the sample onsite or sends it to a lab for analysis. For the test, a nurse or technician places a strip of chemically treated paper, called a dipstick, into the urine. Patches on the dipstick change color when blood or protein is present in urine.\n \nUrine albumin-to-creatinine ratio. A health care provider uses the albumin and creatinine measurement to determine the ratio between the albumin and creatinine in the urine. Creatinine is a waste product in the blood that is filtered in the kidneys and excreted in the urine. A urine albumin-to-creatinine ratio above 30 mg\/g may be a sign of kidney disease.\n \nBlood Test\n \nA blood test involves having blood drawn at a health care providers office or a commercial facility and sending the sample to a lab for analysis.

A diet low in sodium and liquid intake can help reduce edema and lower blood pressure. Reducing saturated fat and cholesterol can help control high levels of lipids, or fats, in the blood.\n \nHealth care providers may recommend that people with kidney disease eat moderate or reduced amounts of protein, though the benefits of reducing protein in a persons diet is still being researched. Proteins break down into waste products that the kidneys filter from the blood. Eating more protein than the body needs may burden the kidneys and cause kidney function to decline faster. However, protein intake that is too low may lead to malnutrition, a condition that occurs when the body does not get enough nutrients. People with kidney disease who are on a restricted protein diet should be monitored with blood tests that can show low nutrient levels.\n \nIn addition, consuming too much alcohol raises blood pressure, so people should limit alcoholic drinkstwo per day for men and one per day for women.\n \nA health care provider can help people change their diet to meet their individual needs.\n \nPhysical Activity\n \nRegular physical activity can lower blood pressure and reduce the chances of other health problems. A health care provider can provide information about how much and what kinds of activity are safe. Most people should try to get at least 30 to 60 minutes of activity most or all days of the week. A person can do all physical activity at once or break up activities into shorter periods of at least 10 minutes each. Moderate activities include brisk walking, dancing, bowling, riding a bike, working in a garden, and cleaning the house.\n \nBody Weight\n \nPeople who are overweight or obese should aim to reduce their weight by 7 to 10 percent during the first year of treatment for high blood pressure. This amount of weight loss can lower the chance of health problems related to high blood pressure. Overweight is defined as a body mass index (BMI)a measurement of weight in relation to heightof 25 to 29. A BMI of 30 or higher is considered obese. A BMI lower than 25 is the goal for keeping blood pressure under control.5\n \nSmoking\n \nPeople who smoke should quit.

For example, taking a dose of insulinor other medication that increases insulin levelsbut then skipping a meal could result in hypoglycemia.\n \nTo help prevent hypoglycemia, people with diabetes should always consider the following:\n \n- Their diabetes medications. A health care provider can explain which diabetes medications can cause hypoglycemia and explain how and when to take medications. For good diabetes management, people with diabetes should take diabetes medications in the recommended doses at the recommended times. In some cases, health care providers may suggest that patients learn how to adjust medications to match changes in their schedule or routine. - Their meal plan. A registered dietitian can help design a meal plan that fits one's personal preferences and lifestyle. Following one's meal plan is important for managing diabetes. People with diabetes should eat regular meals, have enough food at each meal, and try not to skip meals or snacks. Snacks are particularly important for some people before going to sleep or exercising. Some snacks may be more effective than others in preventing hypoglycemia overnight. The dietitian can make recommendations for snacks. - Their daily activity. To help prevent hypoglycemia caused by physical activity, health care providers may advise - checking blood glucose before sports, exercise, or other physical activity and having a snack if the level is below 100 milligrams per deciliter (mg\/dL) - adjusting medication before physical activity - checking blood glucose at regular intervals during extended periods of physical activity and having snacks as needed - checking blood glucose periodically after physical activity - Their use of alcoholic beverages. Drinking alcoholic beverages, especially on an empty stomach, can cause hypoglycemia, even a day or two later. Heavy drinking can be particularly dangerous for people taking insulin or medications that increase insulin production. Alcoholic beverages should always be consumed with a snack or meal at the same time. A health care provider can suggest how to safely include alcohol in a meal plan. - Their diabetes management plan. Intensive diabetes managementkeeping blood glucose as close to the normal range as possible to prevent long-term complicationscan increase the risk of hypoglycemia. Those whose goal is tight control should talk with a health care provider about ways to prevent hypoglycemia and how best to treat it if it occurs.\n \nWhat to Ask the Doctor about Diabetes Medications\n \nPeople who take diabetes medications should ask their doctor or health care provider\n \n- whether their diabetes medications could cause hypoglycemia - when they should take their diabetes medications - how much medication they should take - whether they should keep taking their diabetes medications when they are sick - whether they should adjust their medications before physical activity - whether they should adjust their medications if they skip a meal"} {"_id":"0187bfc7-b5ec-4b85-8dc2-da9625d5e264","text":"Signs and symptoms of hypoglycemia vary from person to person.

If it's still too low, another serving of a quick-fix food should be eaten. These steps should be repeated until the blood glucose level is 70 mg\/dL or above. If the next meal is an hour or more away, a snack should be eaten once the quick-fix foods have raised the blood glucose level to 70 mg\/dL or above.\n \nFor People Who Take Acarbose (Precose) or Miglitol (Glyset)\n \nPeople who take either of these diabetes medications should know that only pure glucose, also called dextroseavailable in tablet or gel formwill raise their blood glucose level during a low blood glucose episode. Other quick-fix foods and drinks won't raise the level quickly enough because acarbose and miglitol slow the digestion of other forms of carbohydrate.\n \nHelp from Others for Severe Hypoglycemia\n \nSevere hypoglycemiavery low blood glucosecan cause a person to pass out and can even be life threatening. Severe hypoglycemia is more likely to occur in people with type 1 diabetes. People should ask a health care provider what to do about severe hypoglycemia. Another person can help someone who has passed out by giving an injection of glucagon. Glucagon will rapidly bring the blood glucose level back to normal and help the person regain consciousness. A health care provider can prescribe a glucagon emergency kit. Family, friends, or coworkersthe people who will be around the person at risk of hypoglycemiacan learn how to give a glucagon injection and when to call 911 or get medical help.\n \nPhysical Activity and Blood Glucose Levels\n \nPhysical activity has many benefits for people with diabetes, including lowering blood glucose levels. However, physical activity can make levels too low and can cause hypoglycemia up to 24 hours afterward. A health care provider can advise about checking the blood glucose level before exercise. For those who take insulin or one of the oral medications that increase insulin production, the health care provider may suggest having a snack if the glucose level is below 100 mg\/dL or adjusting medication doses before physical activity to help avoid hypoglycemia. A snack can prevent hypoglycemia. The health care provider may suggest extra blood glucose checks, especially after strenuous exercise.\n \nHypoglycemia When Driving\n \nHypoglycemia is particularly dangerous if it happens to someone who is driving. People with hypoglycemia may have trouble concentrating or seeing clearly behind the wheel and may not be able to react quickly to road hazards or to the actions of other drivers. To prevent problems, people at risk for hypoglycemia should check their blood glucose level before driving. During longer trips, they should check their blood glucose level frequently and eat snacks as needed to keep the level at 70 mg\/dL or above. If necessary, they should stop for treatment and then make sure their blood glucose level is 70 mg\/dL or above before starting to drive again.\n \nHypoglycemia Unawareness\n \nSome people with diabetes do not have early warning signs of low blood glucose, a condition called hypoglycemia unawareness. This condition occurs most often in people with type 1 diabetes, but it can also occur in people with type 2 diabetes. People with hypoglycemia unawareness may need to check their blood glucose level more often so they know when hypoglycemia is about to occur. They also may need a change in their medications, meal plan, or physical activity routine.\n \nHypoglycemia unawareness develops when frequent episodes of hypoglycemia lead to changes in how the body reacts to low blood glucose levels. The body stops releasing the hormone epinephrine and other stress hormones when blood glucose drops too low. The loss of the body's ability to release stress hormones after repeated episodes of hypoglycemia is called hypoglycemia-associated autonomic failure, or HAAF.\n \nEpinephrine causes early warning symptoms of hypoglycemia such as shakiness, sweating, anxiety, and hunger. Without the release of epinephrine and the symptoms it causes, a person may not realize that hypoglycemia is occurring and may not take action to treat it. A vicious cycle can occur in which frequent hypoglycemia leads to hypoglycemia unawareness and HAAF, which in turn leads to even more severe and dangerous hypoglycemia. Studies have shown that preventing hypoglycemia for a period as short as several weeks can sometimes break this cycle and restore awareness of symptoms. Health care providers may therefore advise people who have had severe hypoglycemia to aim for higher-than-usual blood glucose targets for short-term periods.\n \nBeing Prepared for Hypoglycemia\n \nPeople who use insulin or take an oral diabetes medication that can cause low blood glucose should always be prepared to prevent and treat low blood glucose by\n \n- learning what can trigger low blood glucose levels - having their blood glucose meter available to test glucose levels; frequent testing may be critical for those with hypoglycemia unawareness, particularly before driving a car or engaging in any hazardous activity - always having several servings of quick-fix foods or drinks handy - wearing a medical identification bracelet or necklace - planning what to do if they develop severe hypoglycemia - telling their family, friends, and coworkers about the symptoms of hypoglycemia and how they can help if needed\n \nNormal and Target Blood Glucose Ranges Normal Blood Glucose Levels in People Who Do Not Have Diabetes Upon wakingfasting 70 to 99 mg\/dL After meals 70 to 140 mg\/dL Target Blood Glucose Levels in People Who Have Diabetes Before meals 70 to 130 mg\/dL 1 to 2 hours after the start of a meal below 180 mg\/dL\n \nFor people with diabetes, a blood glucose level below 70 mg\/dL is considered hypoglycemia."} {"_id":"b8d64f64-ccc7-4382-b0f2-4fcbee86ba92","text":"Signs and symptoms of hypoglycemia vary from person to person. People with diabetes should get to know their signs and symptoms and describe them to their friends and family so they can help if needed. School staff should be told how to recognize a child's signs and symptoms of hypoglycemia and how to treat it.\n \nPeople who experience hypoglycemia several times in a week should call their health care provider. They may need a change in their treatment plan: less medication or a different medication, a new schedule for insulin or medication, a different meal plan, or a new physical activity plan.\n \nPrompt Treatment for Hypoglycemia\n \nWhen people think their blood glucose is too low, they should check the blood glucose level of a blood sample using a meter. If the level is below 70 mg\/dL, one of these quick-fix foods should be consumed right away to raise blood glucose:\n \n- 3 or 4 glucose tablets - 1 serving of glucose gelthe amount equal to 15 grams of carbohydrate - 1\/2 cup, or 4 ounces, of any fruit juice - 1\/2 cup, or 4 ounces, of a regularnot dietsoft drink - 1 cup, or 8 ounces, of milk - 5 or 6 pieces of hard candy - 1 tablespoon of sugar or honey\n \nRecommended amounts may be less for small children. The child's doctor can advise about the right amount to give a child.\n \nThe next step is to recheck blood glucose in 15 minutes to make sure it is 70 mg\/dL or above. If it's still too low, another serving of a quick-fix food should be eaten. These steps should be repeated until the blood glucose level is 70 mg\/dL or above. If the next meal is an hour or more away, a snack should be eaten once the quick-fix foods have raised the blood glucose level to 70 mg\/dL or above.\n \nFor People Who Take Acarbose (Precose) or Miglitol (Glyset)\n \nPeople who take either of these diabetes medications should know that only pure glucose, also called dextroseavailable in tablet or gel formwill raise their blood glucose level during a low blood glucose episode. Other quick-fix foods and drinks won't raise the level quickly enough because acarbose and miglitol slow the digestion of other forms of carbohydrate.\n \nHelp from Others for Severe Hypoglycemia\n \nSevere hypoglycemiavery low blood glucosecan cause a person to pass out and can even be life threatening. Severe hypoglycemia is more likely to occur in people with type 1 diabetes. People should ask a health care provider what to do about severe hypoglycemia. Another person can help someone who has passed out by giving an injection of glucagon. Glucagon will rapidly bring the blood glucose level back to normal and help the person regain consciousness. A health care provider can prescribe a glucagon emergency kit. Family, friends, or coworkersthe people who will be around the person at risk of hypoglycemiacan learn how to give a glucagon injection and when to call 911 or get medical help.\n \nPhysical Activity and Blood Glucose Levels\n \nPhysical activity has many benefits for people with diabetes, including lowering blood glucose levels. However, physical activity can make levels too low and can cause hypoglycemia up to 24 hours afterward. A health care provider can advise about checking the blood glucose level before exercise. For those who take insulin or one of the oral medications that increase insulin production, the health care provider may suggest having a snack if the glucose level is below 100 mg\/dL or adjusting medication doses before physical activity to help avoid hypoglycemia. A snack can prevent hypoglycemia. The health care provider may suggest extra blood glucose checks, especially after strenuous exercise.\n \nHypoglycemia When Driving\n \nHypoglycemia is particularly dangerous if it happens to someone who is driving. People with hypoglycemia may have trouble concentrating or seeing clearly behind the wheel and may not be able to react quickly to road hazards or to the actions of other drivers. To prevent problems, people at risk for hypoglycemia should check their blood glucose level before driving. During longer trips, they should check their blood glucose level frequently and eat snacks as needed to keep the level at 70 mg\/dL or above. If necessary, they should stop for treatment and then make sure their blood glucose level is 70 mg\/dL or above before starting to drive again.\n \nHypoglycemia Unawareness\n \nSome people with diabetes do not have early warning signs of low blood glucose, a condition called hypoglycemia unawareness.

Symptoms may include hunger, sweating, shakiness, dizziness, light-headedness, sleepiness, confusion, difficulty speaking, anxiety, and weakness.\n \nTo find the cause of a patient's hypoglycemia, the doctor will use laboratory tests to measure blood glucose, insulin, and other chemicals that play a part in the body's use of energy.\n \nReactive Hypoglycemia\n \nDiagnosis\n \nTo diagnose reactive hypoglycemia, the doctor may\n \n- ask about signs and symptoms - test blood glucose while the patient is having symptoms by taking a blood sample from the arm and sending it to a laboratory for analysis* - check to see whether the symptoms ease after the patient's blood glucose returns to 70 mg\/dL or above after eating or drinking\n \nA blood glucose level below 70 mg\/dL at the time of symptoms and relief after eating will confirm the diagnosis. The oral glucose tolerance test is no longer used to diagnose reactive hypoglycemia because experts now know the test can actually trigger hypoglycemic symptoms.\n \nCauses and Treatment\n \nThe causes of most cases of reactive hypoglycemia are still open to debate. Some researchers suggest that certain people may be more sensitive to the body's normal release of the hormone epinephrine, which causes many of the symptoms of hypoglycemia. Others believe deficiencies in glucagon secretion might lead to reactive hypoglycemia.\n \nA few causes of reactive hypoglycemia are certain, but they are uncommon. Gastricor stomachsurgery can cause reactive hypoglycemia because of the rapid passage of food into the small intestine. Rare enzyme deficiencies diagnosed early in life, such as hereditary fructose intolerance, also may cause reactive hypoglycemia.\n \nTo relieve reactive hypoglycemia, some health professionals recommend\n \n- eating small meals and snacks about every 3 hours - being physically active - eating a variety of foods, including meat, poultry, fish, or nonmeat sources of protein; starchy foods such as whole-grain bread, rice, and potatoes; fruits; vegetables; and dairy products - eating foods high in fiber - avoiding or limiting foods high in sugar, especially on an empty stomach\n \nThe doctor can refer patients to a registered dietitian for personalized meal planning advice. Although some health professionals recommend a diet high in protein and low in carbohydrates, studies have not proven the effectiveness of this kind of diet to treat reactive hypoglycemia.\n \nFasting Hypoglycemia\n \nDiagnosis\n \nFasting hypoglycemia is diagnosed from a blood sample that shows a blood glucose level below 50 mg\/dL after an overnight fast, between meals, or after physical activity.\n \nCauses and Treatment\n \nCauses of fasting hypoglycemia include certain medications, alcoholic beverages, critical illnesses, hormonal deficiencies, some kinds of tumors, and certain conditions occurring in infancy and childhood.\n \nMedications. Medications, including some used to treat diabetes, are the most common cause of hypoglycemia. Other medications that can cause hypoglycemia include\n \n- salicylates, including aspirin, when taken in large doses - sulfa medications, which are used to treat bacterial infections - pentamidine, which treats a serious kind of pneumonia - quinine, which is used to treat malaria\n \nIf using any of these medications causes a person's blood glucose level to fall, the doctor may advise stopping the medication or changing the dose.\n \nAlcoholic beverages. Drinking alcoholic beverages, especially binge drinking, can cause hypoglycemia. The body's breakdown of alcohol interferes with the liver's efforts to raise blood glucose. Hypoglycemia caused by excessive drinking can be serious and even fatal.\n \nCritical illnesses. Some illnesses that affect the liver, heart, or kidneys can cause hypoglycemia. Sepsis, which is an overwhelming infection, and starvation are other causes of hypoglycemia. In these cases, treating the illness or other underlying cause will correct the hypoglycemia.\n \nHormonal deficiencies. Hormonal deficiencies may cause hypoglycemia in very young children, but rarely in adults. Shortages of cortisol, growth hormone, glucagon, or epinephrine can lead to fasting hypoglycemia. Laboratory tests for hormone levels will determine a diagnosis and treatment. Hormone replacement therapy may be advised.\n \nTumors. Insulinomas are insulin-producing tumors in the pancreas. Insulinomas can cause hypoglycemia by raising insulin levels too high in relation to the blood glucose level. These tumors are rare and do not normally spread to other parts of the body. Laboratory tests can pinpoint the exact cause. Treatment involves both short-term steps to correct the hypoglycemia and medical or surgical measures to remove the tumor.\n \nConditions occurring in infancy and childhood. Children rarely develop hypoglycemia. If they do, causes may include the following:\n \n- Brief intolerance to fasting, often during an illness that disturbs regular eating patterns. Children usually outgrow this tendency by age 10. - Hyperinsulinism, which is the overproduction of insulin. This condition can result in temporary hypoglycemia in newborns, which is common in infants of mothers with diabetes. Persistent hyperinsulinism in infants or children is a complex disorder that requires prompt evaluation and treatment by a specialist. - Enzyme deficiencies that affect carbohydrate metabolism. These deficiencies can interfere with the body's ability to process natural sugars, such as fructose and galactose, glycogen, or other metabolites. - Hormonal deficiencies such as lack of pituitary or adrenal hormones.\n \n\n \n*A personal blood glucose monitor cannot be used to diagnose reactive hypoglycemia."} {"_id":"8dfc96d4-ea54-4963-a676-76f094609782","text":"Diabetes-related Hypoglycemia\n \n- When people with diabetes think their blood glucose level is low, they should check it and treat the problem right away. - To treat hypoglycemia, people should have a serving of a quick-fix food, wait 15 minutes, and check their blood glucose again.

Urinalysis is testing of a urine sample. The urine sample is collected in a special container in a health care providers office or commercial facility and can be tested in the same location or sent to a lab for analysis. Urinalysis can show whether the person has an infection or the urine contains substances that form stones. - Blood test. A blood test involves drawing blood at a health care providers office or commercial facility and sending the sample to a lab for analysis. The blood test can show biochemical problems that can lead to kidney stones. - Abdominal x ray. An abdominal x ray is a picture created using radiation and recorded on film or on a computer. The amount of radiation used is small. An x ray is performed at a hospital or outpatient center by an x-ray technician, and the images are interpreted by a radiologista doctor who specializes in medical imaging. Anesthesia is not needed. The person will lie on a table or stand during the x ray. The x-ray machine is positioned over the abdominal area. The person will hold his or her breath as the picture is taken so that the picture will not be blurry. The person may be asked to change position for additional pictures. The x rays can show the location of stones in the kidney or urinary tract. - CT scans. CT scans use a combination of x rays and computer technology to create three-dimensional (3-D) images. A CT scan may include the injection of a special dye, called contrast medium. CT scans require the person to lie on a table that slides into a tunnel-shaped device where the x rays are taken.

Kidney stones may be treated by a general practitioner or by a urologista doctor who specializes in the urinary tract. Small stones usually pass through the urinary tract without treatment. Still, the person may need pain medication and should drink lots of fluids to help move the stone along. Pain control may consist of oral or intravenous (IV) medication, depending on the duration and severity of the pain. IV fluids may be needed if the person becomes dehydrated from vomiting or an inability to drink. A person with a larger stone, or one that blocks urine flow and causes great pain, may need more urgent treatment, such as\n \n- Shock wave lithotripsy. A machine called a lithotripter is used to crush the kidney stone. The procedure is performed by a urologist on an outpatient basis and anesthesia is used. In shock wave lithotripsy, the person lies on a table or, less commonly, in a tub of water above the lithotripter. The lithotripter generates shock waves that pass through the persons body to break the kidney stone into smaller pieces to pass more readily through the urinary tract. - Ureteroscopy. A ureteroscopea long, tubelike instrument with an eyepieceis used to find and retrieve the stone with a small basket or to break the stone up with laser energy. The procedure is performed by a urologist in a hospital with anesthesia. The urologist inserts the ureteroscope into the persons urethra and slides the scope through the bladder and into the ureter. The urologist removes the stone or, if the stone is large, uses a flexible fiber attached to a laser generator to break the stone into smaller pieces that can pass out of the body in the urine. The person usually goes home the same day.\n \n- Percutaneous nephrolithotomy. In this procedure, a wire-thin viewing instrument called a nephroscope is used to locate and remove the stone. The procedure is performed by a urologist in a hospital with anesthesia. During the procedure, a tube is inserted directly into the kidney through a small incision in the persons back. For large stones, an ultrasonic probe that acts as a lithotripter may be needed to deliver shock waves that break the stone into small pieces that can be removed more easily. The person may have to stay in the hospital for several days after the procedure and may have a small tube called a nephrostomy tube inserted through the skin into the kidney.

Health care providers recommend that a person drink 2 to 3 liters of fluid a day. People with cystine stones may need to drink even more. Though water is best, other fluids may also help prevent kidney stones, such as orange juice or lemonade. Talk with your health care provider if you cant drink the recommended amount due to other health problems, such as urinary incontinence, urinary frequency, or kidney failure.\n \nRecommendations based on the specific type of kidney stone include the following:\n \nCalcium Oxalate Stones\n \n- reducing sodium - reducing animal protein, such as meat, eggs, and fish - getting enough calcium from food or taking calcium supplements with food - avoiding foods high in oxalate, such as spinach, rhubarb, nuts, and wheat bran\n \nCalcium Phosphate Stones\n \n- reducing sodium - reducing animal protein - getting enough calcium from food or taking calcium supplements with food\n \nUric Acid Stones\n \n- limiting animal protein\n \nMore information about how changes in diet affect kidney stone formation is provided in the NIDDK health topic, Diet for Kidney Stone Prevention.\n \nMedications\n \nThe health care provider may prescribe certain medications to help prevent kidney stones based on the type of stone formed or conditions that make a person more prone to form stones:\n \n- hyperuricosuriaallopurinol (Zyloprim), which decreases uric acid in the blood and urine - hypercalciuriadiuretics, such as hydrochlorothiazide - hyperoxaluriapotassium citrate to raise the citrate and pH of urine - uric acid stonesallopurinol and potassium citrate - cystine stonesmercaptopropionyl glycine, which decreases cystine in the urine, and potassium citrate - struvite stonesantibiotics, which are bacteria-fighting medications, when needed to treat infections, or acetohydroxamic acid with long-term antibiotic medications to prevent infection\n \nPeople with hyperparathyroidism sometimes develop calcium stones.

He or she will usually ask about the patients symptoms.\n \nPhysical Exam\n \nA physical exam may help diagnose anemia. During a physical exam, a health care provider usually examines a patients body, including checking for changes in skin color.\n \nBlood Tests\n \nTo diagnose anemia, a health care provider may order a complete blood count, which measures the type and number of blood cells in the body. A blood test involves drawing a patients blood at a health care providers office or a commercial facility. A health care provider will carefully monitor the amount of hemoglobin in the patients blood, one of the measurements in a complete blood count.\n \nThe Kidney Disease: Improving Global Outcomes Anemia Work Group recommends that health care providers diagnose anemia in males older than age 15 when their hemoglobin falls below 13 grams per deciliter (g\/dL) and in females older than 15 when it falls below 12 g\/dL.2 If someone has lost at least half of normal kidney function and has low hemoglobin, the cause of anemia may be decreased EPO production.\n \nTwo other blood tests help measure iron levels:\n \n- The ferritin level helps assess the amount of iron stored in the body. A ferritin score below 200 nanograms (ng) per liter may mean a person has iron deficiency that requires treatment.2 - The transferrin saturation score indicates how much iron is available to make red blood cells. A transferrin saturation score below 30 percent can also mean low iron levels that require treatment.2\n \nIn addition to blood tests, the health care provider may order other tests, such as tests for blood loss in stool, to look for other causes of anemia."} {"_id":"d7696899-5f65-477f-8e39-1d61c4d85957","text":"Depending on the cause, a health care provider treats anemia with one or more of the following treatments:\n \nIron\n \nThe first step in treating anemia is raising low iron levels. Iron pills may help improve iron and hemoglobin levels. However, for patients on hemodialysis, many studies show pills do not work as well as iron given intravenously.2\n \nErythropoietin\n \nIf blood tests indicate kidney disease as the most likely cause of anemia, treatment can include injections of a genetically engineered form of EPO. A health care provider, often a nurse, injects the patient with EPO subcutaneously, or under the skin, as needed. Some patients learn how to inject the EPO themselves. Patients on hemodialysis may receive EPO intravenously during hemodialysis.\n \nStudies have shown the use of EPO increases the chance of cardiovascular events, such as heart attack and stroke, in people with CKD. The health care provider will carefully review the medical history of the patient and determine if EPO is the best treatment for the patients anemia. Experts recommend using the lowest dose of EPO that will reduce the need for red blood cell transfusions. Additionally, health care providers should consider the use of EPO only when a patients hemoglobin level is below 10 g\/dL. Health care providers should not use EPO to maintain a patients hemoglobin level above 11.5 g\/dL.2 Patients who receive EPO should have regular blood tests to monitor their hemoglobin so the health care provider can adjust the EPO dose when the level is too high or too low.2 Health care providers should discuss the benefits and risks of EPO with their patients.\n \nMany people with kidney disease need iron supplements and EPO to raise their red blood cell count to a level that will reduce the need for red blood cell transfusions. In some people, iron supplements and EPO will improve the symptoms of anemia.\n \nRed Blood Cell Transfusions\n \nIf a patients hemoglobin falls too low, a health care provider may prescribe a red blood cell transfusion. Transfusing red blood cells into the patients vein raises the percentage of the patients blood that consists of red blood cells, increasing the amount of oxygen available to the body.\n \nVitamin B12 and Folic Acid Supplements\n \nA health care provider may suggest vitamin B12 and folic acid supplements for some people with CKD and anemia. Using vitamin supplements can treat low levels of vitamin B12 or folic acid and help treat anemia. To help ensure coordinated and safe care, people should discuss their use of complementary and alternative medical practices, including their use of dietary supplements, with their health care provider.\n \nRead more about vitamin B12 and folic acid on the MedlinePlus website at www.nlm.nih.gov\/medlineplus.

Others find no link between symptoms and what they eat.\n \nLearning what foods cause symptoms for you may require some trial and error. Keep a food diary and note the times you have bladder pain. The diary might reveal that your flare-ups always happen, for example, after you eat tomatoes or oranges.\n \nSome doctors recommend taking an antacid medicine with meals. The medicine reduces the amount of acid that gets into the urine.\n \nIf you make changes to your diet, remember to eat a variety of healthy foods.\n \nBladder Retraining\n \nBladder retraining is a way to help your bladder hold more urine. People with bladder pain often get in the habit of using the bathroom as soon as they feel pain or urgency. They then feel the need to go before the bladder is really full. The body may get used to frequent voiding. Bladder retraining helps your bladder hold more urine before signaling the urge to urinate.\n \nKeep a bladder diary to track how you are doing. Start by noting the times when you void. Note how much time goes by between voids. For example, you may find that you return to the bathroom every 40 minutes.\n \nTry to stretch out the time between voids. If you usually void every 40 minutes, try to wait at least 50 minutes before you go to the bathroom.\n \nIf your bladder becomes painful, you may use the bathroom. But you may find that your first urge to use the bathroom goes away if you ignore it. Find ways to relax or distract yourself when the first urge strikes.\n \nAfter a few days, you may be able to stretch the time out to 60 or 70 minutes, and you may find that the urge to urinate does not return as soon.\n \nActivity\n \nIf you have IC\/PBS, you may feel the last thing you want to do is exercise. But many people feel that easy activities like walking or gentle stretching exercises help relieve symptoms.\n \nPhysical Therapy\n \nYour doctor or nurse may suggest pelvic exercises. The pelvic muscles hold the bladder in place and help control urination. The first step is to find the right muscle to squeeze. A doctor, nurse, or physical therapist can help you. One way to find the muscles is to imagine that you are trying to stop passing gas. Squeeze the muscles you would use. If you sense a \"pulling\" feeling, you have found the right muscles for pelvic exercises.\n \nYou may need exercises to strengthen those muscles so that it's easier to hold in urine. Or you may need to learn to relax your pelvic muscles if tense muscles are part of your bladder pain.\n \nSome physical therapists specialize in helping people with pelvic pain. Ask your doctor or nurse to help you find a professional trained in pelvic floor physical therapy.\n \nReducing Stress\n \nStress doesn't cause IC\/PBS. But stress can trigger painful flare-ups in someone who has IC\/PBS. Learning to reduce stress in your life by making time for relaxation every day may help control some symptoms of IC\/PBS.\n \nOral Medicines\n \nPain pills like aspirin, ibuprofen, or acetominophen can help control mild bladder pain. Advil and Motrin are examples of ibuprofen. Tylenol is an example of acetominophen. Talk with your doctor if you feel you need a stronger pain medicine.\n \nYour doctor may recommend a medication, pentosan polysulfate sodium, sold as Elmiron, which is approved for treating the pain of IC\/PBS. You may need to take this medicine for up to 6 months before you notice improvement. Elmiron does not work for everyone, but some people with IC\/PBS have found relief taking it. You need a doctor's order for Elmiron. If you don't notice improvement of your symptoms in 6 months, this medicine is not likely to work.\n \nResearchers are also looking at other kinds of medicines. Medicines that treat heartburn might help bladder symptoms by reducing the amount of acid made in the body. Muscle relaxants can keep the bladder from squeezing at the wrong time. Keeping the bladder muscle relaxed helps ease the symptoms of IC\/PBS.\n \nBladder Stretching\n \nThe doctor may stretch the bladder by filling it with liquid. You will be given an anesthetic to prevent pain and help relax your bladder muscles. Some patients have said their symptoms were helped after this treatment.\n \nBladder Medicines\n \nMany patients who have IC\/PBS find relief after a treatment in which their bladders are filled with a liquid medicine. The doctor guides a tube into your bladder and slowly fills the bladder with a liquid that eases irritation of the bladder wall. The liquid may be a compound called DMSO or a solution that contains heparin and a pain medicine called lidocaine.\n \nYou will keep the liquid in your bladder for about 15 minutes and then release it. You can have this treatment once every week or every other week for 1 or 2 months. You may not feel any better until the third or fourth treatment.\n \nNerve Stimulation\n \nIf you have tried diet changes, exercise, and medicines and nothing seems to help, you may wish to think about nerve stimulation. This treatment sends mild electrical pulses to the nerves that control the bladder.\n \nAt first, you may try a system that sends the pulses through electrodes placed on your skin. If this therapy works for you, you may consider having a device put in your body. The device delivers small pulses of electricity to the nerves around the bladder.\n \nFor some patients, nerve stimulation relieves bladder pain as well as urinary frequency and urgency. For others, the treatment relieves frequency and urgency but not pain. For still other patients, it does not work.\n \nScientists are not sure why nerve stimulation works. Some believe that the electrical pulses block the pain signals carried in the nerves. If your brain doesn't receive the nerve signal, you don't feel the pain. Others believe that the electricity releases endorphins, which are hormones that block pain naturally.\n \nSurgery\n \nAs a last resort, your doctor might suggest surgery to remove part or all of the bladder. Surgery does not cure the pain of IC\/PBS in all cases, but if you have tried every other option and your pain is still unbearable, surgery might be considered.\n \nTalk with your doctor and family about the possible benefits and side effects."} {"_id":"77c227cd-1b81-4fb6-bf28-9ad9a7cc49ca","text":"- Bladder problems have many possible causes. - Your doctor will need to do tests to find the cause of your bladder problems.

The urine sample is collected in a special container in a health care providers office or commercial facility and can be tested in the same location or sent to a lab for analysis. For the test, a nurse or technician places a strip of chemically treated paper, called a dipstick, into the urine. Patches on the dipstick change color when RBCs are present in urine. When blood is visible in the urine or a dipstick test of the urine indicates the presence of RBCs, a health care provider examines the urine with a microscope to make an initial diagnosis of hematuria. The next step is to diagnose the cause of the hematuria.\n \nThe health care provider will take a thorough medical history. If the history suggests a cause that does not require treatment, the urine should be tested again after 48 hours for the presence of RBCs. If two of three urine samples show too many RBCs when viewed with a microscope, more serious causes should be explored. The health care provider may order one or more of the following tests:\n \n- Urinalysis. Further testing of the urine may be done to check for problems that can cause hematuria, such as infection, kidney disease, and cancer. The presence of white blood cells signals a UTI. RBCs that are misshapen or clumped together to form little tubes, called casts, may indicate kidney disease. Large amounts of protein in the urine, called proteinuria, may also indicate kidney disease. The urine can also be tested for the presence of cancer cells. - Blood test. A blood test involves drawing blood at a health care providers office or commercial facility and sending the sample to a lab for analysis. A blood test can show the presence of high levels of creatinine, a waste product of normal muscle breakdown, which may indicate kidney disease. - Biopsy. A biopsy is a procedure that involves taking a piece of kidney tissue for examination with a microscope. The biopsyis performed by a health care provider in a hospital with light sedation and local anesthetic. The health care provider uses imaging techniques such as ultrasound or a computerized tomography (CT) scan to guide the biopsy needle into the kidney. The kidney tissue is examined in a lab by a pathologista doctor who specializes in diagnosing diseases. The test helps diagnose the type of kidney disease causing hematuria. - Cystoscopy. Cystoscopy is a procedure that uses a tubelike instrument to look inside the urethra and bladder. Cystoscopy is performed by a health care provider in the office, an outpatient facility, or a hospital with local anesthesia. However, in some cases, sedation and regional or general anesthesia are needed. Cystoscopy may be used to look for cancer cells in the bladder, particularly if cancer cells are found with urinalysis. More information is provided in the NIDDK health topic,Cystoscopy and Ureteroscopy. - Kidney imaging tests. Intravenous pyelogram (IVP) is an x ray of the urinary tract. A special dye, called contrast medium, is injected into a vein in the persons arm, travels through the body to the kidneys, and makes urine visible on the x ray. The contrast medium also shows any blockage in the urinary tract. When a small mass is found with IVP, another imaging test, such as an ultrasound, CT scan, or magnetic resonance imaging (MRI), can be used to further study the mass. Imaging tests are performed in an outpatient center or hospital by a specially trained technician, and the images are interpreted by a radiologista doctor who specializes in medical imaging. Anesthesia is not needed, though light sedation may be used in some cases. Imaging tests may show a tumor, a kidney or bladder stone, an enlarged prostate, or other blockage of the normal flow of urine.

Your doctor might ask you questions such as\n \n- Have you ever had surgery? - What medicines do you take? - How sure are you that you can get and keep an erection? - When you have erections, how often are they hard enough for sex? - During sex, how often are you able to keep your erection? - When you try to have sex, how often are you happy with the sex? - How would you rate your level of sexual desire? - How often are you able to reach climax and ejaculate? - Do you have an erection when you wake up in the morning? - Do you use illegal drugs, drink alcohol, or smoke?\n \nThe answers to these questions will help your doctor understand the problem.\n \nBring a list of all the medicines you take, or the actual medicines, to show to your doctor.\n \nMental Health Questions\n \nYour doctor may ask you questions about your mental health. For example, the doctor may ask if you feel nervous or depressed. He or she may also ask you to answer questions on paper. The doctor may also ask your sexual partner questions to get more information about the problem.\n \nPhysical Exam\n \nA physical exam can help your doctor find the cause of your ED. As part of the exam, the doctor will examine your testes and penis, take your blood pressure, and check for problems with your blood flow.\n \nBlood Tests\n \nA blood test involves drawing your blood at a doctors office or a commercial facility and sending the sample to a lab for analysis. Blood tests can show possible causes of ED, such as diabetes, clogged blood vessels, or chronic kidney disease. Low levels of testosterone in your blood can explain why you may have lost interest in sex.\n \nNighttime Erection Test\n \nDuring a nighttime erection test, you wear a plastic band around your penis to test whether you have nighttime erections. The band easily breaks if your penis expands. This test shows if you had at least one erection during the night. Another test uses an electronic device that can record the number of erections, how long they last, and how firm they are. A man normally has three to five erections during the night while he sleeps.

You may do this test in your home or in a special sleep lab.\n \nInjection Test\n \nDuring an injection test, the doctor will inject a medicine into your penis to cause an erection. If the erection is not firm or does not last, it may mean you have a problem with blood flow. This test most often takes place in the doctors office.\n \nDoppler Penile Ultrasound\n \nAn x-ray technician most often performs a Doppler penile ultrasound in a doctors office or an outpatient center. During a Doppler penile ultrasound, the x-ray technician or doctor lightly passes a device over your penis to create images of blood vessels in your penis. An injection is used to create an erection.

Untreated diabetes or high blood pressure may be part of the cause of your ED.\n \nLifestyle changes. For some men, the following lifestyle changes help:\n \n- quitting smoking - drinking less alcohol - increasing physical activity - stopping illegal drug use\n \nChanging medicines you take to treat other health problems. Talk with your doctor about all the medicines you are taking, including over-the-counter medicines. The doctor may find that a medicine you are taking is causing your ED. Your doctor may be able to give you another medicine that works in a different way, or your doctor may tell you to try a lower dose of your medicine.\n \nCounseling. Counseling can help couples deal with the emotional effects of ED. Some couples find that counseling adds to the medical treatment by making their relationship stronger.\n \nPrescribing Medicines to Treat Your Erectile Dysfunction\n \nDepending on which medicine your doctor gives you, you may take it by mouth or by putting it directly into your penis.\n \nMedicine by mouth. Your doctor may be able to prescribe a pill to treat ED. Common medicines include\n \n- sildenafil (Viagra) - vardenafil (Levitra, Staxyn) - tadalafil (Cialis) - avanafil (Stendra)\n \nIf your health is generally good, your doctor may prescribe one of these medicines. You should not take any of these pills to treat ED if you take any nitrates, a type of heart medicine. All ED pills work by increasing blood flow to the penis. They do not cause automatic erections. Talk with your doctor about when to take the pill. You may need to experiment to find out how soon the pill takes effect.\n \nOther forms of medicine. Taking a pill doesnt work for all men. You may need to use medicine that goes directly into your penis. You may use an injection into the shaft of your penis, or you may use medicine placed in your urethra, at the tip of your penis. The urethra is the tube that carries urine and semen outside of the body. Your doctor will teach you how to use the medicines. They most often cause an erection within minutes. These medicines can be successful, even if other treatments fail.\n \nPrescribing a Vacuum Device\n \nAnother way to create an erection is to use a device with a specially designed vacuum tube. You put your penis into the tube, which is connected to a pump. As air is pumped out of the tube, blood flows into your penis and makes it larger and firmer. You then move a specially designed elastic ring from the end of the tube to the base of your penis to keep the blood from flowing back into your body. You may find that using a vacuum device requires some practice.\n \nPerforming Surgery\n \nIf the other options fail, you may need surgery to treat ED.\n \nImplanted devices. A urologist can place a device that fills with fluid or a device with bendable rods inside the penis to create an erection.\n \nOne kind of implant uses two cylinders that fill with fluid like a balloon. Tubing connects the cylinders to a small ball that holds the fluid. You fill the cylinders by squeezing a small pump that the urologist places under the skin of the scrotum, in front of your testes. The pump causes fluid to flow into the two cylinders in your penis, making it hard. The fluid can make the penis slightly longer and wider. An implant that uses fluids instead of bendable rods leaves the penis in a more natural state when not in use.\n \nImplants that bend most often have two rods that the urologist places side by side in your penis during surgery. You use your hands to adjust the position of the rods to make your penis straight. Your penis does not get larger. After sex, you bend the rods down.\n \nImplanted devices do not affect the way sex feels or the ability to have an orgasm.\n \nOnce you have an implanted device, you must use the device to have an erection every time. Talk with your doctor about the pros and cons of having an implanted device.\n \nSurgery to repair blood vessels. Doctors treat some cases of ED with surgery to repair the blood vessels that carry blood to the penis. This type of surgery is more likely to work in men younger than 30."} {"_id":"c8d1367a-0514-4ed4-88cc-5613ba056a7d","text":"You can prevent many of the causes of ED by making healthy lifestyle choices.

He or she will ask the patient or caregiver to provide a medical and family history, specifically if anyone in the patient's family has a history of celiac disease.\n \nPhysical Exam\n \nA physical exam may help diagnose celiac disease. During a physical exam, a health care provider usually\n \n- examines the patient's body for malnutrition or a rash - uses a stethoscope to listen to sounds within the abdomen - taps on the patient's abdomen checking for bloating and pain\n \nBlood Tests\n \nA blood test involves drawing blood at a health care provider's office or a commercial facility and sending the sample to a lab for analysis. A blood test can show the presence of antibodies that are common in celiac disease.\n \nIf blood test results are negative and a health care provider still suspects celiac disease, he or she may order additional blood tests, which can affect test results.\n \nBefore the blood tests, patients should continue to eat a diet that includes foods with gluten, such as breads and pastas. If a patient stops eating foods with gluten before being tested, the results may be negative for celiac disease even if the disease is present.\n \nIntestinal Biopsy\n \nIf blood tests suggest that a patient has celiac disease, a health care provider will perform a biopsy of the patient's small intestine to confirm the diagnosis. A biopsy is a procedure that involves taking a piece of tissue for examination with a microscope. A health care provider performs the biopsy in an outpatient center or a hospital. He or she will give the patient light sedation and a local anesthetic. Some patients may receive general anesthesia.\n \nDuring the biopsy, a health care provider removes tiny pieces of tissue from the patient's small intestine using an endoscopea small, flexible camera with a light. The health care provider carefully feeds the endoscope down the patient's esophagus and into the stomach and small intestine. A small camera mounted on the endoscope transmits a video image to a monitor, allowing close examination of the intestinal lining. The health care provider then takes the samples using tiny tools that he or she passes through the endoscope. A pathologista doctor who specializes in examining tissues to diagnose diseasesexamines the tissue in a lab. The test can show damage to the villi in the small intestine.\n \nSkin Biopsy\n \nWhen a health care provider suspects that a patient has dermatitis herpetiformis, he or she will perform a skin biopsy. A skin biopsy is a procedure that involves removing tiny pieces of skin tissue for examination with a microscope. A health care provider performs the biopsy in an outpatient center or a hospital. The patient receives a local anesthetic; however, in some cases, the patient will require general anesthesia.\n \nA pathologist examines the skin tissue in a lab and checks the tissue for antibodies that are common in celiac disease. If the skin tissue tests positive for the antibodies, a health care provider will perform blood tests to confirm celiac disease. If the skin biopsy and blood tests both suggest celiac disease, the patient may not need an intestinal biopsy for diagnosis.\n \n\n \nGenetic Tests In some cases, a health care provider will order genetic blood tests to confirm or rule out a diagnosis of celiac disease. Most people with celiac disease have gene pairs that contain at least one of the human leukocyte antigen (HLA) gene variants.4 However, these variants are also common in people without celiac disease, so their presence alone cannot diagnose celiac disease.

Health care providers typically refer people to a dietitian who specializes in treating people with the disease. The dietitian will teach the person to avoid gluten while following a healthy and nutritious diet. The dietitian will give the person instructions for how to\n \n- read food and product labels and identify ingredients that contain gluten - make healthy choices about the types of foods to eat - design everyday meal plans\n \nFor most people, following a gluten-free diet will stop symptoms, heal existing intestinal damage, and prevent further damage. Symptoms may improve within days to weeks of starting the diet. The small intestine usually heals in 3 to 6 months in children. Complete healing can take several years in adults. Once the intestine heals, the villi will absorb nutrients from food into the bloodstream normally.\n \nSome people with celiac disease show no improvement after starting a gluten-free diet. The most common reason for poor response to dietary changes is that people are still consuming small amounts of gluten, which can damage the small intestineeven in people without symptoms. Most people start responding to the gluten-free diet once they find and eliminate hidden sources of gluten from their diet. Hidden sources of gluten include additives made with wheat, such as\n \n- modified food starch - preservatives - stabilizers\n \n\n \nDid you know that medications and nonfood products may contain gluten? Medications, supplements, and other products may also contain lecithin, a hidden source of gluten. People with celiac disease should ask a pharmacist about the ingredients in - prescription and over-the-counter medications - vitamins and mineral supplements - herbal and nutritional supplements Other products can be ingested or transferred from a person's hands to his or her mouth. Reading product labels can help people avoid gluten exposure. If a product's label does not list its ingredients, the manufacturer should provide a list upon request. Products that can contain gluten include - lipstick, lip gloss, and lip balm - cosmetics - skin and hair products - toothpaste and mouthwash - glue on stamps and envelopes - children's modeling dough, such as Play-Doh\n \nSome people who continue to have symptoms even after changing their diet may have other conditions or disorders that are more common in people with celiac disease. These conditions may include\n \n- small intestinal bacterial overgrowth, which happens when too many bacteria grow in the small intestine - pancreatic exocrine insufficiency, in which the pancreas does not produce enough digestive juice - microscopic colitis, an inflammation of the colon that a health care provider can see only with a microscope - IBS - lactose intolerance, a condition in which people have symptoms after consuming milk or milk products - other food intolerances, which may occur because of continued damage to the intestine\n \nIn some cases, people continue to have difficulty absorbing nutrients despite following a strict gluten-free diet. People with this condition, known as refractory celiac disease, have severely damaged intestines that cannot heal. Their intestines are not absorbing enough nutrients, so they may need to receive nutrients intravenously. Researchers continue to evaluate medications to treat refractory celiac disease.\n \nDepending on a person's age at diagnosis, some complications of celiac disease will not improve, such as short stature and dental enamel defects.\n \nFor people with dermatitis herpetiformis, skin symptoms generally respond to a gluten-free diet and may recur if a person adds gluten back into his or her diet. Medications such as dapsone can control the rash's symptoms. Dapsone does not treat intestinal symptoms or damage, so people with dermatitis herpetiformis should maintain a gluten-free diet, even if they don't have digestive symptoms.

Foods regulated by the U.S. Department of Agriculture, including meat and egg products, are not subject to this regulation. The regulation requires that any food with the term \"gluten-free\" on the label must meet all of the requirements of the definition, including that the food should contain fewer than 20 parts per million of gluten. The FDA rule also requires foods with the claims \"no gluten,\" \"free of gluten,\" and \"without gluten\" to meet the definition for \"gluten-free.\" If a food that is labeled \"gluten-free\" includes \"wheat\" on the ingredients list or \"contains wheat\" after the list, the following statement must be included on the label: \"The wheat has been processed to allow this food to meet the Food and Drug Administration requirements for gluten-free food.\" If this statement is included, people with celiac disease may consume foods labeled \"gluten-free.\""} {"_id":"a4b6ec01-b42d-4c42-aeac-a6becce88532","text":"- Celiac disease is an immune disorder in which people cannot tolerate gluten because it damages the lining of their small intestine and prevents absorption of nutrients. - When people with celiac disease eat foods or use products containing gluten, their immune system responds by damaging or destroying villithe tiny, fingerlike projections on the inner lining of the small intestine. - A person may experience digestive signs and symptoms, or symptoms in other parts of the body. - Recognizing celiac disease can be difficult because some of its symptoms are similar to those of other diseases and conditions. - Dermatitis herpetiformis is a chronic, itchy, blistering skin rashusually on the elbows, knees, buttocks, back, or scalpthat affects about 5 to 10 percent of people with celiac disease. - Signs and symptoms of celiac disease vary from person to person because of numerous factors. - Some people with celiac disease have no signs or symptoms; however, they can still develop complications of the disease over time.

However, too much iron in the body leads to iron overloada buildup of extra iron that, without treatment, can damage organs such as the liver, heart, and pancreas; endocrine glands; and joints.\n \nThe three types of hemochromatosis are primary hemochromatosis, also called hereditary hemochromatosis; secondary hemochromatosis; and neonatal hemochromatosis."} {"_id":"98ebc868-2202-4b31-97de-0a15718272b1","text":"Primary Hemochromatosis\n \nInherited genetic defects cause primary hemochromatosis, and mutations in the HFE gene are associated with up to 90 percent of cases.1 The HFE gene helps regulate the amount of iron absorbed from food. The two known mutations of HFE are C282Y and H63D. C282Y defects are the most common cause of primary hemochromatosis.\n \nPeople inherit two copies of the HFE geneone copy from each parent. Most people who inherit two copies of the HFE gene with the C282Y defect will have higher-than-average iron absorption. However, not all of these people will develop health problems associated with hemochromatosis. One recent study found that 31 percent of people with two copies of the C282Y defect developed health problems by their early fifties.2 Men who develop health problems from HFE defects typically develop them after age 40.1 Women who develop health problems from HFE defects typically develop them after menopause.1\n \nPeople who inherit two H63D defects or one C282Y and one H63D defect may have higher-than-average iron absorption.3 However, they are unlikely to develop iron overload and organ damage.\n \nRare defects in other genes may also cause primary hemochromatosis. Mutations in the hemojuvelin or hepcidin genes cause juvenile hemochromatosis, a type of primary hemochromatosis. People with juvenile hemochromatosis typically develop severe iron overload and liver and heart damage between ages 15 and 30.\n \nSecondary Hemochromatosis\n \nHemochromatosis that is not inherited is called secondary hemochromatosis. The most common cause of secondary hemochromatosis is frequent blood transfusions in people with severe anemia. Anemia is a condition in which red blood cells are fewer or smaller than normal, which means they carry less oxygen to the bodys cells. Types of anemia that may require frequent blood transfusions include\n \n- congenital, or inherited, anemias such as sickle cell disease, thalassemia, and Fanconis syndrome - severe acquired anemias, which are not inherited, such as aplastic anemia and autoimmune hemolytic anemia\n \nLiver diseasessuch as alcoholic liver disease, nonalcoholic steatohepatitis, and chronic hepatitis C infectionmay cause mild iron overload. However, this iron overload causes much less liver damage than the underlying liver disease causes.\n \nNeonatal Hemochromatosis\n \nNeonatal hemochromatosis is a rare disease characterized by liver failure and death in fetuses and newborns. Researchers are studying the causes of neonatal hemochromatosis and believe more than one factor may lead to the disease.\n \nExperts previously considered neonatal hemochromatosis a type of primary hemochromatosis. However, recent studies suggest genetic defects that increase iron absorption do not cause this disease. Instead, the mothers immune system may produce antibodiesproteins made by the immune system to protect the body from foreign substances such as bacteria or virusesthat damage the liver of the fetus. Women who have had one child with neonatal hemochromatosis are at risk for having more children with the disease.4 Treating these women during pregnancy with intravenous (IV) immunoglobulina solution of antibodies from healthy peoplecan prevent fetal liver damage.4\n \nResearchers supported by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) recently found that a combination of exchange transfusionremoving blood and replacing it with donor bloodand IV immunoglobulin is an effective treatment for babies born with neonatal hemochromatosis.5"} {"_id":"0b24ab26-932e-497e-8fba-f41db6b529e1","text":"A person with hemochromatosis may notice one or more of the following symptoms:\n \n- joint pain - fatigue, or feeling tired - unexplained weight loss - abnormal bronze or gray skin color - abdominal pain - loss of sex drive\n \nNot everyone with hemochromatosis will develop these symptoms."} {"_id":"c1766199-7611-4001-81a8-6129c699d9ce","text":"Without treatment, iron may build up in the organs and cause complications, including\n \n- cirrhosis, or scarring of liver tissue - diabetes - irregular heart rhythms or weakening of the heart muscle - arthritis - erectile dysfunction\n \nThe complication most often associated with hemochromatosis is liver damage.

After taking a medical history, a health care provider will perform a physical exam, which may help diagnose hemochromatosis. During a physical exam, a health care provider usually - examines a patients body - uses a stethoscope to listen to bodily sounds - taps on specific areas of the patients body - Blood tests. A blood test involves drawing blood at a health care providers office or a commercial facility and sending the sample to a lab for analysis. Blood tests can determine whether the amount of iron stored in the body is higher than normal:1 - The transferrin saturation test shows how much iron is bound to the protein that carries iron in the blood. Transferrin saturation values above or equal to 45 percent are considered abnormal. - The serum ferritin test detects the amount of ferritina protein that stores ironin the blood. Levels above 300 g\/L in men and 200 g\/L in women are considered abnormal. Levels above 1,000 g\/L in men or women indicate a high chance of iron overload and organ damage. If either test shows higher-than-average levels of iron in the body, health care providers can order a special blood test that can detect two copies of the C282Y mutation to confirm the diagnosis. If the mutation is not present, health care providers will look for other causes. - Liver biopsy. Health care providers may perform a liver biopsy, a procedure that involves taking a piece of liver tissue for examination with a microscope for signs of damage or disease. The health care provider may ask the patient to temporarily stop taking certain medications before the liver biopsy. The health care provider may ask the patient to fast for 8 hours before the procedure. During the procedure, the patient lies on a table, right hand resting above the head. The health care provider applies a local anesthetic to the area where he or she will insert the biopsy needle. If needed, a health care provider will also give sedatives and pain medication. The health care provider uses a needle to take a small piece of liver tissue. He or she may use ultrasound, computerized tomography scans, or other imaging techniques to guide the needle. After the biopsy, the patient must lie on the right side for up to 2 hours and is monitored an additional 2 to 4 hours before being sent home. A health care provider performs a liver biopsy at a hospital or an outpatient center. The health care provider sends the liver sample to a pathology lab where the pathologista doctor who specializes in diagnosing diseaselooks at the tissue with a microscope and sends a report to the patients health care provider. The biopsy shows how much iron has accumulated in the liver and whether the patient has liver damage.\n \nHemochromatosis is rare, and health care providers may not think to test for this disease. Thus, the disease is often not diagnosed or treated. The initial symptoms can be diverse, vague, and similar to the symptoms of many other diseases. Health care providers may focus on the symptoms and complications caused by hemochromatosis rather than on the underlying iron overload. However, if a health care provider diagnoses and treats the iron overload caused by hemochromatosis before organ damage has occurred, a person can live a normal, healthy life.\n \n\n \nWho should be tested for hemochromatosis? Experts recommend testing for hemochromatosis in people who have symptoms, complications, or a family history of the disease. Some researchers have suggested widespread screening for the C282Y mutation in the general population. However, screening is not cost-effective. Although the C282Y mutation occurs quite frequently, the disease caused by the mutation is rare, and many people with two copies of the mutation never develop iron overload or organ damage. Researchers and public health officials suggest the following: - Siblings of people who have hemochromatosis should have their blood tested to see if they have the C282Y mutation. - Parents, children, and other close relatives of people who have hemochromatosis should consider being tested. - Health care providers should consider testing people who have severe and continuing fatigue, unexplained cirrhosis, joint pain or arthritis, heart problems, erectile dysfunction, or diabetes because these health issues may result from hemochromatosis."} {"_id":"879c72ef-080e-428d-bb31-53cf17d0f64a","text":"Health care providers treat hemochromatosis by drawing blood. This process is called phlebotomy. Phlebotomy rids the body of extra iron. This treatment is simple, inexpensive, and safe.\n \nBased on the severity of the iron overload, a patient will have phlebotomy to remove a pint of blood once or twice a week for several months to a year, and occasionally longer. Health care providers will test serum ferritin levels periodically to monitor iron levels. The goal is to bring serum ferritin levels to the low end of the average range and keep them there. Depending on the lab, the level is 25 to 50 g\/L.\n \nAfter phlebotomy reduces serum ferritin levels to the desired level, patients may need maintenance phlebotomy treatment every few months. Some patients may need phlebotomies more often. Serum ferritin tests every 6 months or once a year will help determine how often a patient should have blood drawn. Many blood donation centers provide free phlebotomy treatment for people with hemochromatosis.\n \nTreating hemochromatosis before organs are damaged can prevent complications such as cirrhosis, heart problems, arthritis, and diabetes. Treatment cannot cure these conditions in patients who already have them at diagnosis. However, treatment will help most of these conditions improve. The treatments effectiveness depends on the degree of organ damage. For example, treating hemochromatosis can stop the progression of liver damage in its early stages and lead to a normal life expectancy.

Infections and medications may also cause the disease.\n \nAutoimmune Disorders\n \nUp to 80 percent of Addisons disease cases are caused by an autoimmune disorder, which is when the bodys immune system attacks the bodys own cells and organs.2 In autoimmune Addisons, which mainly occurs in middle-aged females, the immune system gradually destroys the adrenal cortexthe outer layer of the adrenal glands.2\n \nPrimary adrenal insufficiency occurs when at least 90 percent of the adrenal cortex has been destroyed.1 As a result, both cortisol and aldosterone are often lacking. Sometimes only the adrenal glands are affected. Sometimes other endocrine glands are affected as well, as in polyendocrine deficiency syndrome.\n \nPolyendocrine deficiency syndrome is classified into type 1 and type 2. Type 1 is inherited and occurs in children. In addition to adrenal insufficiency, these children may have\n \n- underactive parathyroid glands, which are four pea-sized glands located on or near the thyroid gland in the neck; they produce a hormone that helps maintain the correct balance of calcium in the body. - slow sexual development. - pernicious anemia, a severe type of anemia; anemia is a condition in which red blood cells are fewer than normal, which means less oxygen is carried to the bodys cells. With most types of anemia, red blood cells are smaller than normal; however, in pernicious anemia, the cells are bigger than normal. - chronic fungal infections. - chronic hepatitis, a liver disease.\n \nResearchers think type 2, which is sometimes called Schmidts syndrome, is also inherited. Type 2 usually affects young adults and may include\n \n- an underactive thyroid gland, which produces hormones that regulate metabolism - slow sexual development - diabetes, in which a person has high blood glucose, also called high blood sugar or hyperglycemia - vitiligo, a loss of pigment on areas of the skin\n \nInfections\n \nTuberculosis (TB), an infection that can destroy the adrenal glands, accounts for 10 to 15 percent of Addisons disease cases in developed countries.1 When primary adrenal insufficiency was first identified by Dr. Thomas Addison in 1849, TB was the most common cause of the disease. As TB treatment improved, the incidence of Addisons disease due to TB of the adrenal glands greatly decreased. However, recent reports show an increase in Addisons disease from infections such as TB and cytomegalovirus. Cytomegalovirus is a common virus that does not cause symptoms in healthy people; however, it does affect babies in the womb and people who have a weakened immune systemmostly due to HIV\/AIDS.2 Other bacterial infections, such as Neisseria meningitidis, which is a cause of meningitis, and fungal infections can also lead to Addisons disease.\n \nOther Causes\n \nLess common causes of Addisons disease are\n \n- cancer cells in the adrenal glands - amyloidosis, a serious, though rare, group of diseases that occurs when abnormal proteins, called amyloids, build up in the blood and are deposited in tissues and organs - surgical removal of the adrenal glands - bleeding into the adrenal glands - genetic defects including abnormal adrenal gland development, an inability of the adrenal glands to respond to ACTH, or a defect in adrenal hormone production - medication-related causes, such as from anti-fungal medications and the anesthetic etomidate, which may be used when a person undergoes an emergency intubationthe placement of a flexible, plastic tube through the mouth and into the trachea, or windpipe, to assist with breathing\n \n\n \n2"} {"_id":"b43dc821-0213-40dc-9c50-3267db1dd236","text":"A lack of CRH or ACTH causes secondary adrenal insufficiency. The lack of these hormones in the body can be traced to several possible sources.\n \nStoppage of Corticosteroid Medication\n \nA temporary form of secondary adrenal insufficiency may occur when a person who has been taking a synthetic glucocorticoid hormone, called a corticosteroid, for a long time stops taking the medication. Corticosteroids are often prescribed to treat inflammatory illnesses such as rheumatoid arthritis, asthma, and ulcerative colitis. In this case, the prescription doses often cause higher levels than those normally achieved by the glucocorticoid hormones created by the body. When a person takes corticosteroids for prolonged periods, the adrenal glands produce less of their natural hormones. Once the prescription doses of corticosteroid are stopped, the adrenal glands may be slow to restart their production of the bodys glucocorticoids. To give the adrenal glands time to regain function and prevent adrenal insufficiency, prescription corticosteroid doses should be reduced gradually over a period of weeks or even months. Even with gradual reduction, the adrenal glands might not begin to function normally for some time, so a person who has recently stopped taking prescription corticosteroids should be watched carefully for symptoms of secondary adrenal insufficiency.\n \nSurgical Removal of Pituitary Tumors\n \nAnother cause of secondary adrenal insufficiency is surgical removal of the usually noncancerous, ACTH-producing tumors of the pituitary gland that cause Cushings syndrome. Cushings syndrome is a hormonal disorder caused by prolonged exposure of the bodys tissues to high levels of the hormone cortisol. When the tumors are removed, the source of extra ACTH is suddenly gone and a replacement hormone must be taken until the bodys adrenal glands are able to resume their normal production of cortisol. The adrenal glands might not begin to function normally for some time, so a person who has had an ACTH-producing tumor removed and is going off of his or her prescription corticosteroid replacement hormone should be watched carefully for symptoms of adrenal insufficiency.\n \nMore information is provided in the NIDDK health topic, Cushings Syndrome.\n \nChanges in the Pituitary Gland\n \nLess commonly, secondary adrenal insufficiency occurs when the pituitary gland either decreases in size or stops producing ACTH. These events can result from\n \n- tumors or an infection in the pituitary - loss of blood flow to the pituitary - radiation for the treatment of pituitary or nearby tumors - surgical removal of parts of the hypothalamus - surgical removal of the pituitary"} {"_id":"30b6a404-a651-426e-b173-8553715614ad","text":"In its early stages, adrenal insufficiency can be difficult to diagnose. A health care provider may suspect it after reviewing a persons medical history and symptoms.\n \nA diagnosis of adrenal insufficiency is confirmed through hormonal blood and urine tests. A health care provider uses these tests first to determine whether cortisol levels are too low and then to establish the cause. Imaging studies of the adrenal and pituitary glands can be useful in helping to establish the cause.\n \nA lab technician performs the following tests in a health care providers office, a commercial facility, or a hospital.\n \nHormonal Blood and Urine Tests\n \n- ACTH stimulation test. The ACTH stimulation test is the most commonly used test for diagnosing adrenal insufficiency. In this test, the patient is given an intravenous (IV) injection of synthetic ACTH, and samples of blood, urine, or both are taken before and after the injection. The cortisol levels in the blood and urine samples are measured in a lab. The normal response after an ACTH injection is a rise in blood and urine cortisol levels. People with Addisons disease or longstanding secondary adrenal insufficiency have little or no increase in cortisol levels. Both low- and high-dose ACTH stimulation tests may be used depending on the suspected cause of adrenal insufficiency. For example, if secondary adrenal insufficiency is mild or has only recently occurred, the adrenal glands may still respond to ACTH because they have not yet shut down their own production of hormone. Some studies have suggested a low dose1 microgram (mcg)may be more effective in detecting secondary adrenal insufficiency because the low dose is still enough to raise cortisol levels in healthy people, yet not in people with mild or recent secondary adrenal insufficiency. However, recent research has shown that a significant proportion of healthy children and adults can fail the low-dose test, which may lead to unnecessary treatment. Therefore, some health care providers favor using a 250 mcg ACTH test for more accurate results. - CRH stimulation test. When the response to the ACTH test is abnormal, a CRH stimulation test can help determine the cause of adrenal insufficiency. In this test, the patient is given an IV injection of synthetic CRH, and blood is taken before and 30, 60, 90, and 120 minutes after the injection. The cortisol levels in the blood samples are measured in a lab. People with Addisons disease respond by producing high levels of ACTH, yet no cortisol. People with secondary adrenal insufficiency do not produce ACTH or have a delayed response. CRH will not stimulate ACTH secretion if the pituitary is damaged, so no ACTH response points to the pituitary as the cause. A delayed ACTH response points to the hypothalamus as the cause.\n \nDiagnosis during Adrenal Crisis\n \nAlthough a reliable diagnosis is not possible during adrenal crisis, measurement of blood ACTH and cortisol during the crisisbefore treatment with corticosteroids is givenis often enough to make a preliminary diagnosis. Low blood sodium, low blood glucose, and high blood potassium are also sometimes present at the time of adrenal crisis. Once the crisis is controlled, an ACTH stimulation test can be performed to help make a specific diagnosis. More complex lab tests are sometimes used if the diagnosis remains unclear."} {"_id":"d5f36628-e790-4b84-b359-058c88112531","text":"After Addisons disease is diagnosed, health care providers may use the following tests to look at the adrenal glands, find out whether the disease is related to TB, or identify antibodies associated with autoimmune Addisons disease.\n \n- Ultrasound of the abdomen.

A specially trained technician performs the procedure in a health care providers office, an outpatient center, or a hospital, and a radiologista doctor who specializes in medical imaginginterprets the images; a patient does not need anesthesia. The images can show abnormalities in the adrenal glands, such as enlargement or small size, nodules, or signs of calcium deposits, which may indicate bleeding. - Tuberculin skin test. A tuberculin skin test measures how a patients immune system reacts to the bacteria that cause TB. A small needle is used to put some testing material, called tuberculin, under the skin. A nurse or lab technician performs the test in a health care providers office; a patient does not need anesthesia. In 2 to 3 days, the patient returns to the health care provider, who will check to see if the patient had a reaction to the test. The test can show if adrenal insufficiency could be related to TB. To test whether a person has TB infection, which is when TB bacteria live in the body without making the person sick, a special TB blood test is used. To test whether a person has TB disease, which is when TB bacteria are actively attacking a persons lungs and making the person sick, other tests such as a chest x ray and a sample of sputumphlegm that is coughed up from deep in the lungsmay be needed. - Antibody blood tests.

The blood test can detect antibodiesproteins made by the immune system to protect the body from foreign substancesassociated with autoimmune Addisons disease.\n \nAfter secondary adrenal insufficiency is diagnosed, health care providers may use the following tests to obtain a detailed view of the pituitary gland and assess how it is functioning:\n \n- Computerized tomography (CT) scan. CT scans use a combination of x rays and computer technology to create images. For a CT scan, the patient may be given a solution to drink and an injection of a special dye, called contrast medium. CT scans require the patient to lie on a table that slides into a tunnel-shaped device where the x rays are taken. An x-ray technician performs the procedure in an outpatient center or a hospital, and a radiologist interprets the images. The patient does not need anesthesia. A CT scan can show size and shape of the pituitary gland to find out if an abnormality is present. - Magnetic resonance imaging (MRI). MRI machines use radio waves and magnets to produce detailed pictures of the bodys internal organs and soft tissues without using x rays. An MRI may include the injection of contrast medium. With most MRI machines, the patient lies on a table that slides into a tunnel-shaped device that may be open ended or closed at one end; some machines are designed to allow the patient to lie in a more open space. A specially trained technician performs the procedure in an outpatient center or a hospital, and a radiologist interprets the images. The patient does not need anesthesia, though people with a fear of confined spaces may receive light sedation, taken by mouth. MRIs can be used to produce a three-dimensional (3-D) image of the hypothalamus and the pituitary gland to find out if an abnormality is present. - Hormonal blood tests.

Hashimotos disease is also an autoimmune disorder.\n \nNormally, the immune system protects the body against foreign invaderssuch as viruses and bacteriathat can cause illness. But in autoimmune diseases, the immune system attacks the bodys own cells and organs.

At first, the leakage raises hormone levels in the blood, leading to hyperthyroidismwhen thyroid hormone levels are too highthat lasts for 1 or 2 months. Most people then develop hypothyroidism before the thyroid is completely healed.\n \nSeveral types of thyroiditis can cause hyperthyroidism followed by hypothyroidism:\n \n- Subacute thyroiditis. This condition involves painful inflammation and enlargement of the thyroid. Experts are not sure what causes subacute thyroiditis, but it may be related to a viral or bacterial infection. The condition usually goes away on its own in a few months. - Postpartum thyroiditis. This type of thyroiditis develops after a woman gives birth. For more information, see the section titled What happens with pregnancy and thyroid conditions? - Silent thyroiditis.

The ultrasensitive TSH test is usually the first test a health care provider performs. This test detects even tiny amounts of TSH in the blood and is the most accurate measure of thyroid activity available. Generally, a TSH reading above normal means a person has hypothyroidism and a reading below normal means a person has hyperthyroidism.\n \nMildly elevated TSH without symptoms indicates subclinical hypothyroidism. Some health care providers treat subclinical hypothyroidism immediately. Others prefer to leave it untreated but monitor their patients for signs that the condition is worsening.\n \nHealth care providers may conduct additional tests to help confirm the diagnosis or determine the cause of hypothyroidism.\n \nT4 test. This test measures the actual amount of circulating thyroid hormone in the blood. In hypothyroidism, the level of T4 in the blood is lower than normal.\n \nThyroid autoantibody test.

Normally, bacteria that enter the urinary tract are rapidly removed by the body before they cause symptoms. However, sometimes bacteria overcome the bodys natural defenses and cause infection. An infection in the urethra is called urethritis. A bladder infection is called cystitis. Bacteria may travel up the ureters to multiply and infect the kidneys. A kidney infection is called pyelonephritis."} {"_id":"2faa56e8-aca9-4cc5-bb0e-ec0a3c62b396","text":"The urinary tract is the body's drainage system for removing wastes and extra water. The urinary tract includes two kidneys, two ureters, a bladder, and a urethra. The kidneys are a pair of bean-shaped organs, each about the size of a fist and located below the ribs, one on each side of the spine, toward the middle of the back. Every minute, a persons kidneys filter about 3 ounces of blood, removing wastes and extra water. The wastes and extra water make up the 1 to 2 quarts of urine a person produces each day. The urine travels from the kidneys down two narrow tubes called the ureters. The urine is then stored in a balloonlike organ called the bladder and emptied through the urethra, a tube at the bottom of the bladder.\n \nWhen the bladder empties, a muscle called the sphincter relaxes and urine flows out of the body through the urethra. The opening of the urethra is at the end of the penis in males and in front of the vagina in females."} {"_id":"131802a5-e5de-407b-8ab9-d662a533831e","text":"Most UTIs are caused by bacteria that live in the bowel. The bacterium Escherichia coli (E. coli) causes the vast majority of UTIs. Microbes called Chlamydia and Mycoplasma can infect the urethra and reproductive system but not the bladder. Chlamydia and Mycoplasma infections may be sexually transmitted and require treatment of sexual partners.\n \nThe urinary tract has several systems to prevent infection. The points where the ureters attach to the bladder act like one-way valves to prevent urine from backing up toward the kidneys, and urination washes microbes out of the body. In men, the prostate gland produces secretions that slow bacterial growth. In both sexes, immune defenses also prevent infection. But despite these safeguards, infections still occur.

One factor is that a womans urethra is shorter, allowing bacteria quicker access to the bladder. Also, a womans urethral opening is near sources of bacteria from the anus and vagina. For women, the lifetime risk of having a UTI is greater than 50 percent.2 UTIs in men are not as common as in women but can be serious when they occur."} {"_id":"b7e5612d-af00-4e2c-a1e1-c3572e94662e","text":"Although everyone has some risk, some people are more prone to getting UTIs than others. People with spinal cord injuries or other nerve damage around the bladder have difficulty emptying their bladder completely, allowing bacteria to grow in the urine that stays in the bladder. Anyone with an abnormality of the urinary tract that obstructs the flow of urinea kidney stone or enlarged prostate, for exampleis at risk for a UTI. People with diabetes or problems with the bodys natural defense system are more likely to get UTIs.\n \nSexual activity can move microbes from the bowel or vaginal cavity to the urethral opening. If these microbes have special characteristics that allow them to live in the urinary tract, it is harder for the body to remove them quickly enough to prevent infection. Following sexual intercourse, most women have a significant number of bacteria in their urine, but the body normally clears them within 24 hours. However, some forms of birth control increase the risk of UTI. In some women, certain spermicides may irritate the skin, increasing the risk of bacteria invading surrounding tissues. Using a diaphragm may slow urinary flow and allow bacteria to multiply. Condom use is also associated with increased risk of UTIs, possibly because of the increased trauma that occurs to the vagina during sexual activity. Using spermicides with diaphragms and condoms can increase risk even further.\n \nAnother common source of infection is catheters, or tubes, placed in the urethra and bladder. Catheters interfere with the bodys ability to clear microbes from the urinary tract. Bacteria travel through or around the catheter and establish a place where they can thrive within the bladder. A person who cannot urinate in the normal way or who is unconscious or critically ill often needs a catheter for more than a few days. The Infectious Diseases Society of America recommends using catheters for the shortest time possible to reduce the risk of a UTI.3\n \nRecurrent Infections\n \nMany women suffer from frequent UTIs. About 20 percent of young women with a first UTI will have a recurrent infection.4 With each UTI, the risk that a woman will continue having recurrent UTIs increases.5 Some women have three or more UTIs a year. However, very few women will have frequent infections throughout their lives. More typically, a woman will have a period of 1 or 2 years with frequent infections, after which recurring infections cease.\n \nMen are less likely than women to have a first UTI. But once a man has a UTI, he is likely to have another because bacteria can hide deep inside prostate tissue. Anyone who has diabetes or a problem that makes it hard to urinate may have repeat infections.\n \nResearch funded by the National Institutes of Health (NIH) suggests that one factor behind recurrent UTIs may be the ability of bacteria to attach to cells lining the urinary tract. One NIH-funded study found that bacteria formed a protective film on the inner lining of the bladder in mice.6 If a similar process can be demonstrated in humans, the discovery may lead to new treatments to prevent recurrent UTIs. Another line of research has indicated that women who are nonsecretors of certain blood group antigens may be more prone to recurrent UTIs because the cells lining the vagina and urethra may allow bacteria to attach more easily. A nonsecretor is a person with an A, B, or AB blood type who does not secrete the normal antigens for that blood type in bodily fluids, such as fluids that line the bladder wall.7\n \nInfections during Pregnancy\n \nPregnant women seem no more prone to UTIs than other women. However, when a UTI does occur in a pregnant woman, it is more likely to travel to the kidneys. According to some reports, about 4 to 5 percent of pregnant women develop a UTI.8 Scientists think that hormonal changes and shifts in the position of the urinary tract during pregnancy make it easier for bacteria to travel up the ureters to the kidneys and cause infection. For this reason, health care providers routinely screen pregnant women for bacteria in the urine during the first 3 months of pregnancy."} {"_id":"fa6ae694-f0e5-4ca4-a210-0d397d51ab14","text":"Symptoms of a UTI vary by age, gender, and whether a catheter is present.

The amount of urine may be very small. Older women and men are more likely to be tired, shaky, and weak and have muscle aches and abdominal pain. Urine may look cloudy, dark, or bloody or have a foul smell. In a person with a catheter, the only symptom may be fever that cannot be attributed to any other cause. Normally, UTIs do not cause fever if they are in the bladder. A fever may mean the infection has reached the kidneys or has penetrated the prostate.

Because bacteria can be found in the urine of healthy individuals, a UTI is diagnosed based both on symptoms and a laboratory test. The person will be asked to give a clean catch urine sample by washing the genital area and collecting a midstream sample of urine in a sterile container. This method of collecting urine helps prevent bacteria around the genital area from getting into the sample and confusing the test results. Usually, the sample is sent to a laboratory, although some health care providers offices are equipped to do the testing. For people with recurring infections and patients in the hospital, the urine may be cultured. The culture is performed by placing part of the urine sample in a tube or dish with a substance that encourages any bacteria present to grow. Once the bacteria have multiplied, which usually takes 1 to 3 days, they can be identified. The health care provider may also order a sensitivity test, which tests the bacteria for sensitivity to different antibiotics to see which medication is best for treating the infection.\n \nIf a person has recurrent UTIs, the health care provider may order some additional tests to determine if the persons urinary tract is normal.\n \nKidney and bladder ultrasound. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. The procedure is performed in a health care providers office, outpatient center, or hospital by a specially trained technician, and the images are interpreted by a radiologista doctor who specializes in medical imaging; anesthesia is not needed. The images can show abnormalities in the kidneys and bladder. However, this test cannot reveal all important urinary abnormalities or measure how well the kidneys work.\n \nVoiding cystourethrogram. This test is an x-ray image of the bladder and urethra taken while the bladder is full and during urination, also called voiding. As the person lies on the x-ray table, a health care provider inserts the tip of a thin, flexible tube called a catheter through the urethra into the bladder. The bladder and urethra are filled with a special dye called contrast medium, to make the structures clearly visible on the x-ray images. The x rays are taken from various angles while the bladder is full of contrast medium. The catheter is then removed and x-ray images are taken during urination. The procedure is performed in a health care providers office, outpatient center, or hospital by an x-ray technician. The technician is supervised by a radiologist while the images are taken. The radiologist then interprets the images. Anesthesia is not needed, but light sedation may be used for some people. This test can show abnormalities of the inside of the urethra and bladder. The test can also determine whether the flow of urine is normal when the bladder empties.\n \nComputerized tomography (CT) scan. CT scans use a combination of x rays and computer technology to create three-dimensional (3-D) images. A CT scan may include the injection of contrast medium. CT scans require the person to lie on a table that slides into a tunnel-shaped device where the x rays are taken. The procedure is performed in an outpatient center or hospital by an x-ray technician, and the images are interpreted by a radiologist; anesthesia is not needed. CT scans can provide clearer, more detailed images to help the health care provider understand the problem.\n \nMagnetic resonance imaging (MRI). MRI machines use radio waves and magnets to produce detailed pictures of the bodys internal organs and soft tissues without using x rays. An MRI may include an injection of contrast medium. With most MRI machines, the person lies on a table that slides into a tunnel-shaped device that may be open ended or closed at one end; some newer machines are designed to allow the person to lie in a more open space. The procedure is performed in an outpatient center or hospital by a specially trained technician, and the images are interpreted by a radiologist; anesthesia is not needed though light sedation may be used for people with a fear of confined spaces. Like CT scans, MRIs can provide clearer, more detailed images.\n \nRadionuclide scan. A radionuclide scan is an imaging technique that relies on the detection of small amounts of radiation after injection of radioactive chemicals. Because the dose of the radioactive chemicals is small, the risk of causing damage to cells is low. Special cameras and computers are used to create images of the radioactive chemicals as they pass through the kidneys. Radionuclide scans are performed in a health care providers office, outpatient center, or hospital by a specially trained technician, and the images are interpreted by a radiologist; anesthesia is not needed. Radioactive chemicals injected into the blood can provide information about kidney function. Radioactive chemicals can also be put into the fluids used to fill the bladder and urethra for x ray, MRI, and CT imaging.\n \nUrodynamics. Urodynamic testing is any procedure that looks at how well the bladder, sphincters, and urethra are storing and releasing urine. Most of these tests are performed in the office of a urologista doctor who specializes in urinary problemsby a urologist, physician assistant, or nurse practitioner. Some procedures may require light sedation to keep a person calm. Most urodynamic tests focus on the bladders ability to hold urine and empty steadily and completely. Urodynamic tests can also show whether the bladder is having abnormal contractions that cause leakage. A health care provider may order these tests if there is evidence that the person has some kind of nerve damage.\n \nCystoscopy. Cystoscopy is a procedure that uses a tubelike instrument to look inside the urethra and bladder. Cystoscopy is performed by a doctor in a health care providers office, outpatient facility, or hospital with local anesthesia. However, in some cases, sedation and regional or general anesthesia are needed. Cystoscopy may be used to look for swelling, redness, and other signs of infection."} {"_id":"67262264-6ef5-4978-8f40-c09da911170a","text":"Most UTIs are caused by bacteria, which are treated with bacteria-fighting medications called antibiotics or antimicrobials. The choice of medication and length of treatment depend on the patients history and the type of bacteria causing the infection. Some antibiotics may be ruled out if a person has allergies to them. The sensitivity test takes 48 hours to complete and is especially useful in helping the health care provider select the antibiotic most likely to be effective in treating an infection. Longer treatment may be needed if the first antibiotic given is not effective.\n \nWhen a UTI occurs in a healthy person with a normal, unobstructed urinary tract, the term uncomplicated is used to describe the infection. Most young women who have UTIs have uncomplicated UTIs, which can be cured with 2 or 3 days of treatment. Single-dose treatment is less effective. Longer treatment causes more side effects and is not more effective. A follow-up urinalysis helps to confirm the urinary tract is infection-free. Taking the full course of treatment is important because symptoms may disappear before the infection is fully cleared.\n \nComplicated UTIs occur when a personfor example, a pregnant woman or a transplant patientis weakened by another condition. A UTI is also complicated when the person has a structural or functional abnormality of the urinary tract, such as an obstructive kidney stone or prostate enlargement that squeezes the urethra. Health care providers should assume that men and boys have a complicated UTI until proven otherwise.\n \nSeverely ill patients with kidney infections may be hospitalized until they can take fluids and needed medications on their own. Kidney infections may require several weeks of antibiotic treatment. Kidney infections in adults rarely lead to kidney damage or kidney failure unless they go untreated or are associated with urinary tract obstruction.\n \nBladder infections are generally self-limiting, but antibiotic treatment significantly shortens the duration of symptoms. People usually feel better within a day or two of treatment. Symptoms of kidney and prostate infections last longer. Drinking lots of fluids and urinating frequently will speed healing. If needed, various medications are available to relieve the pain of a UTI. A heating pad on the back or abdomen may also help.\n \nRecurrent Infections in Women\n \nHealth care providers may advise women who have recurrent UTIs to try one of the following treatment options:\n \n- Take low doses of the prescribed antibiotic daily for 6 months or longer. If taken at bedtime, the medication remains in the bladder longer and may be more effective. NIH-supported research has shown this therapy to be effective without causing serious side effects. - Take a single dose of an antibiotic after sexual intercourse. - Take a short course2 or 3 daysof an antibiotic when symptoms appear.\n \nTo try to prevent an infection, health care providers may suggest women\n \n- drink plenty of water every day - urinate when the need arises and avoid resisting the urge to urinate - urinate after sexual intercourse - switch to a different method of birth control if recurring UTIs are a problem\n \nInfections during Pregnancy\n \nDuring pregnancy, bacterial infection of the urineeven in the absence of symptomscan pose risks to both the mother and the baby. Some antibiotics are not safe to take during pregnancy. In selecting the best treatments, health care providers consider various factors such as the medications effectiveness, the stage of pregnancy, the mothers health, and potential effects on the fetus.\n \nComplicated Infections\n \nCuring infections that stem from a urinary obstruction or other systemic disorder depends on finding and correcting the underlying problem, sometimes with surgery. If the root cause goes untreated, this group of patients is at risk for kidney damage. Also, such infections tend to arise from a wider range of bacteria and sometimes from more than one type of bacteria at a time.\n \nInfections in Men\n \nUrinary tract infections in men are often the result of an obstructionfor example, a urinary stone or enlarged prostateor are from a catheter used during a medical procedure. The first step in treating such an infection is to identify the infecting organism and the medications to which it is sensitive.\n \nProstate infectionschronic bacterial prostatitisare harder to cure because antibiotics may be unable to penetrate infected prostate tissue effectively. For this reason, men with bacterial prostatitis often need long-term treatment with a carefully selected antibiotic. UTIs in men are frequently associated with acute bacterial prostatitis, which can be life threatening if not treated urgently."} {"_id":"17c9ce0c-be4e-43b4-bfa7-d89f3680391c","text":"Changing some daily habits may help a person prevent recurrent UTIs.\n \nEating, Diet, and Nutrition\n \nDrinking lots of fluid can help flush bacteria from the system. Water is best. Most people should try for six to eight, 8-ounce glasses a day. Talk with your health care provider if you cant drink the recommended amount due to other health problems, such as urinary incontinence, urinary frequency, or kidney failure.\n \nUrination Habits\n \nA person should urinate often and when the urge arises. Bacteria can grow when urine stays in the bladder too long. Women and men should urinate shortly after sex to flush away bacteria that might have entered the urethra during sex. Drinking a glass of water will also help flush bacteria away.\n \nAfter using the toilet, women should wipe from front to back. This step is most important after a bowel movement to keep bacteria from getting into the urethra.\n \nClothing\n \nCotton underwear and loose-fitting clothes should be worn, so air can keep the area around the urethra dry. Tight-fitting jeans and nylon underwear should be avoided because they can trap moisture and help bacteria grow.\n \nBirth Control\n \nFor women, using a diaphragm or spermicide for birth control can lead to UTIs by increasing bacteria growth. A woman who has trouble with UTIs should try switching to a new form of birth control. Unlubricated condoms or spermicidal condoms increase irritation, which may help bacteria grow. Switching to lubricated condoms without spermicide or using a nonspermicidal lubricant may help prevent UTIs."} {"_id":"178f8ce9-5d94-4097-bd9e-b70f6f82c968","text":"- Most urinary tract infections (UTIs) arise from one type of bacteria, Escherichia coli (E. coli), which normally lives in the bowel. - Symptoms of a UTI in adults may include the following: - a frequent and intense urge to urinate - a painful, burning feeling in the bladder or urethra during urination - feeling tired, shaky, and weak - muscle aches - abdominal pain - only small amounts of urine passed, despite a strong urge to urinate - cloudy, dark, or bloody urine or urine that has a foul smell - pain in the back or side below the ribs - nausea and vomiting - Fever may indicate a kidney or prostate infection. - Because bacteria can be found in the urine of healthy individuals, a UTI is diagnosed based both on symptoms and a laboratory test. - UTIs are treated with bacteria-fighting medications called antibiotics or antimicrobials."} {"_id":"851b6f50-3f96-490e-befe-1e0ef157182c","text":"Diabetes is a complex group of diseases with a variety of causes. People with diabetes have high blood glucose, also called high blood sugar or hyperglycemia.\n \nDiabetes is a disorder of metabolismthe way the body uses digested food for energy. The digestive tract breaks down carbohydratessugars and starches found in many foodsinto glucose, a form of sugar that enters the bloodstream. With the help of the hormone insulin, cells throughout the body absorb glucose and use it for energy. Insulin is made in the pancreas, an organ located behind the stomach. As the blood glucose level rises after a meal, the pancreas is triggered to release insulin. Within the pancreas, clusters of cells called islets contain beta cells, which make the insulin and release it into the blood.\n \nDiabetes develops when the body doesnt make enough insulin or is not able to use insulin effectively, or both. As a result, glucose builds up in the blood instead of being absorbed by cells in the body. The bodys cells are then starved of energy despite high blood glucose levels.\n \nOver time, high blood glucose damages nerves and blood vessels, leading to complications such as heart disease, stroke, kidney disease, blindness, dental disease, and amputations. Other complications of diabetes may include increased susceptibility to other diseases, loss of mobility with aging, depression, and pregnancy problems.\n \nMain Types of Diabetes\n \nThe three main types of diabetes are type 1, type 2, and gestational diabetes:\n \n- Type 1 diabetes, formerly called juvenile diabetes, is usually first diagnosed in children, teenagers, and young adults. In this type of diabetes, the beta cells of the pancreas no longer make insulin because the bodys immune system has attacked and destroyed them. - Type 2 diabetes, formerly called adult-onset diabetes, is the most common type of diabetes. About 90 to 95 percent of people with diabetes have type 2.1 People can develop type 2 diabetes at any age, even during childhood, but this type of diabetes is most often associated with older age. Type 2 diabetes is also associated with excess weight, physical inactivity, family history of diabetes, previous history of gestational diabetes, and certain ethnicities. Type 2 diabetes usually begins with insulin resistance, a condition linked to excess weight in which muscle, liver, and fat cells do not use insulin properly. As a result, the body needs more insulin to help glucose enter cells to be used for energy. At first, the pancreas keeps up with the added demand by producing more insulin. But in time, the pancreas loses its ability to produce enough insulin in response to meals, and blood glucose levels rise. - Gestational diabetes is a type of diabetes that develops only during pregnancy. The hormones produced during pregnancy increase the amount of insulin needed to control blood glucose levels. If the body cant meet this increased need for insulin, women can develop gestational diabetes during the late stages of pregnancy. Gestational diabetes usually goes away after the baby is born. Shortly after pregnancy, 5 to 10 percent of women with gestational diabetes continue to have high blood glucose levels and are diagnosed as having diabetes, usually type 2.1 Research has shown that lifestyle changes and the diabetes medication, metformin, can reduce or delay the risk of type 2 diabetes in these women. Babies born to mothers who had gestational diabetes are also more likely to develop obesity and type 2 diabetes as they grow up. More information about gestational diabetes is provided in the NIDDK health topic, What I need to know about Gestational Diabetes,or by calling 18008608747.\n \nOther Types of Diabetes\n \nMany other types of diabetes exist, and a person can exhibit characteristics of more than one type. For example, in latent autoimmune diabetes in adults, people show signs of both type 1 and type 2 diabetes. Other types of diabetes include those caused by genetic defects, diseases of the pancreas, excess amounts of certain hormones resulting from some medical conditions, medications that reduce insulin action, chemicals that destroy beta cells, infections, rare autoimmune disorders, and genetic syndromes associated with diabetes.\n \nMore information about other types of diabetes is provided in the NIDDK health topic, Causes of Diabetes, or by calling 18008608747."} {"_id":"32ecfafe-fa1f-4ba4-ad61-b0d4b6c80725","text":"Prediabetes is when blood glucose levels are higher than normal but not high enough for a diagnosis of diabetes.

All diabetes blood tests involve drawing blood at a health care providers office or commercial facility and sending the sample to a lab for analysis. Lab analysis of blood is needed to ensure test results are accurate. Glucose measuring devices used in a health care providers office, such as finger-stick devices, are not accurate enough for diagnosis but may be used as a quick indicator of high blood glucose.\n \nTesting enables health care providers to find and treat diabetes before complications occur and to find and treat prediabetes, which can delay or prevent type 2 diabetes from developing.\n \nAny one of the following tests can be used for diagnosis:*\n \n- an A1C test, also called the hemoglobin A1c, HbA1c, or glycohemoglobin test - a fasting plasma glucose (FPG) test - an oral glucose tolerance test (OGTT)\n \n*Not all tests are recommended for diagnosing all types of diabetes. See the individual test descriptions for details.\n \nAnother blood test, the random plasma glucose (RPG) test, is sometimes used to diagnose diabetes during a regular health checkup. If the RPG measures 200 milligrams per deciliter or above, and the individual also shows symptoms of diabetes, then a health care provider may diagnose diabetes.\n \nSymptoms of diabetes include\n \n- increased urination - increased thirst - unexplained weight loss\n \nOther symptoms can include fatigue, blurred vision, increased hunger, and sores that do not heal.\n \nAny test used to diagnose diabetes requires confirmation with a second measurement unless clear symptoms of diabetes exist.\n \nThe following table provides the blood test levels for diagnosis of diabetes for nonpregnant adults and diagnosis of prediabetes.\n \nA1C Test\n \nThe A1C test is used to detect type 2 diabetes and prediabetes but is not recommended for diagnosis of type 1 diabetes or gestational diabetes. The A1C test is a blood test that reflects the average of a persons blood glucose levels over the past 3 months and does not show daily fluctuations. The A1C test is more convenient for patients than the traditional glucose tests because it does not require fasting and can be performed at any time of the day.\n \nThe A1C test result is reported as a percentage. The higher the percentage, the higher a persons blood glucose levels have been. A normal A1C level is below 5.7 percent.\n \nAn A1C of 5.7 to 6.4 percent indicates prediabetes. People diagnosed with prediabetes may be retested in 1 year. People with an A1C below 5.7 percent maystill be at risk for diabetes, depending on the presence of other characteristics that put them at risk, also known as risk factors. People with an A1C above 6.0 percent should be considered at very high risk of developing diabetes. A level of 6.5 percent or above means a person has diabetes.\n \nLaboratory analysis. When the A1C test is used for diagnosis, the blood sample must be sent to a laboratory using a method that is certified by the NGSP to ensure the results are standardized. Blood samples analyzed in a health care providers office, known as point-of-care tests, are not standardized for diagnosing diabetes.\n \nAbnormal results. The A1C test can be unreliable for diagnosing or monitoring diabetes in people with certain conditions known to interfere with the results. Interference should be suspected when A1C results seem very different from the results of a blood glucose test. People of African, Mediterranean, or Southeast Asian descent or people with family members with sickle cell anemia or a thalassemia are particularly at risk of interference.\n \nHowever, not all of the A1C tests are unreliable for people with these diseases. The NGSP provides information about which A1C tests are appropriate to use for specific types of interference and details on any problems with the A1C test at www.ngsp.org.\n \nFalse A1C test results may also occur in people with other problems that affect their blood or hemoglobin such as chronic kidney disease, liver disease, or anemia.\n \nMore information about limitations of the A1C test and different forms of sickle cell anemia is provided in the NIDDK health topic, For People of African, Mediterranean, or Southeast Asian Heritage: Important Information about Diabetes Blood Tests, or by calling 18008608747.\n \nChanges in Diagnostic Testing\n \nIn the past, the A1C test was used to monitor blood glucose levels but not for diagnosis. The A1C test has now been standardized, and in 2009, an international expert committee recommended it be used for diagnosis of type 2 diabetes and prediabetes.2\n \nMore information about the A1C test is provided in the NIDDK health topic, The A1C Test and Diabetes, or by calling 18008608747.\n \nFasting Plasma Glucose Test\n \nThe FPG test is used to detect diabetes and prediabetes. The FPG test has been the most common test used for diagnosing diabetes because it is more convenient than the OGTT and less expensive. The FPG test measures blood glucose in a person who has fasted for at least 8 hours and is most reliable when given in the morning.\n \nPeople with a fasting glucose level of 100 to 125 mg\/dL have impaired fasting glucose (IFG), or prediabetes. A level of 126 mg\/dL or above, confirmed by repeating the test on another day, means a person has diabetes.\n \nOral Glucose Tolerance Test\n \nThe OGTT can be used to diagnose diabetes, prediabetes, and gestational diabetes. Research has shown that the OGTT is more sensitive than the FPG test, but it is less convenient to administer. When used to test for diabetes or prediabetes, the OGTT measures blood glucose after a person fasts for at least 8 hours and 2 hours after the person drinks a liquid containing 75 grams of glucose dissolved in water.\n \nIf the 2-hour blood glucose level is between 140 and 199 mg\/dL, the person has a type of prediabetes called impaired glucose tolerance (IGT). If confirmed by a second test, a 2-hour glucose level of 200 mg\/dL or above means a person has diabetes."} {"_id":"fe5160a6-f10d-418d-9b31-f585fe4f8a6c","text":"Health care providers test for gestational diabetes using the OGTT.

Women found to have diabetes at the first visit to the health care provider after becoming pregnant may be diagnosed with type 2 diabetes.\n \nDefining Safe Blood Glucose Levels for Pregnancy\n \nMany studies have shown that gestational diabetes can cause complications for the mother and baby. An international, multicenter study, the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) study, showed that the higher a pregnant womans blood glucose is, the higher her risk of pregnancy complications. The HAPO researchers found that pregnancy complications can occur at blood glucose levels that were once considered to be normal.\n \nBased on the results of the HAPO study, new guidelines for diagnosis of gestational diabetes were recommended by the International Association of the Diabetes and Pregnancy Study Groups in 2011. So far, the new guidelines have been adopted by the American Diabetes Association (ADA)3 but not by the American College of Obstetricians and Gynecologists (ACOG)4 or other medical organizations.

A surgeon performs laparoscopic hernia repair with the patient under general anesthesia. The surgeon makes several small, half-inch incisions in the lower abdomen and inserts a laparoscopea thin tube with a tiny video camera attached. The camera sends a magnified image from inside the body to a video monitor, giving the surgeon a close-up view of the hernia and surrounding tissue.

People with diabetes have problems converting food to energy. After food is eaten, it is broken down into a sugar called glucose. Glucose is then carried by the blood to cells throughout the body. The hormone insulin, made in the pancreas, helps the body change blood glucose into energy. People with diabetes, however, either no longer make enough insulin, or their insulin doesn't work properly, or both.\n \nType 2 diabetes\n \nType 2 diabetes is the most common type in American Indians. This type of diabetes can occur at any age, even during childhood. People develop type 2 diabetes because the cells in the muscles, liver, and fat do not use insulin properly. Eventually, the body cannot make enough insulin. As a result, the amount of glucose in the blood increases while the cells are starved of energy. Over time, high blood glucose damages nerves and blood vessels, leading to problems such as heart disease, stroke, blindness, kidney failure, and amputation.\n \nOther kinds of diabetes\n \nType 1 diabetes\n \nType 1 diabetes is rare in American Indians. People develop type 1 diabetes when their bodies no longer make any insulin. Type 1 is usually first diagnosed in children or young adults but can develop at any age.\n \nGestational diabetes\n \nGestational diabetes is first diagnosed during pregnancy. It occurs when the body doesn't use insulin properly. Having an American Indian family background raises the risk of developing gestational diabetes.

Keeping your blood pressure and cholesterol on target also helps you stay healthy.\n \nIf you are pregnant, plan to breastfeed your baby. Ask your health care provider for the names of people to call for help learning to breastfeed. Besides being good for your baby, breastfeeding is good for you. Studies done with the help of Pima Indian volunteers have shown that breastfeeding may lower the baby's risk of becoming overweight and getting diabetes.\n \nGetting Started.\n \nMaking changes in your life such as eating less can be hard. You can make the changes easier by taking these steps:\n \n- Make a plan to change something that you do. - Decide exactly what you will do and when you will do it. - Plan what you need to get ready. - Think about what might prevent you from reaching your goal. - Find family and friends who will support and encourage you. - Decide how you will reward yourselfwith a nonfood itemor activitywhen you do what you have planned.\n \nYour health care provider, a registered dietitian, or a counselor can help you make a plan.\n \nReach and Maintain a Reasonable Body Weight.\n \nYour weight affects your health in many ways. Being overweight can keep your body from making and using insulin correctly. The extra weight may also cause high blood pressure. The DPP study showed that losing even a few pounds can help lower your risk of developing type 2 diabetes, because weight loss helps your body use insulin more effectively. Every pound you lose lowers your risk of getting diabetes. In the DPP, people who lost 5 to 7 percent of their body weight lowered their risk of developing type 2 diabetes. They had less than half the risk of developing diabetes as people who didn't make lifestyle changes. A 5- to 7-percent weight loss for a 150-pound person, for example, would be about 7 to 10 pounds. If you're overweight, choose sensible ways to lose weight.\n \n- Don't use crash diets. Instead, eat smaller servings of the foods you usually have, and limit the amount of fat you eat. - Increase your physical activity. Aim for at least 30 minutes of exercise most days of the week. Do something you enjoy, like biking or walking with a friend. - Set a reasonable weight-loss goal, such as losing about a pound a week. Aim for a long-term goal of losing the number of pounds that's right for you.\n \nChoosing My Weight Loss Goal.\n \nLosing 5 to 7 percent of your total weight can help lower your risk of getting type 2 diabetes. You are more likely to lose weight if:\n \n- you're physically active - you cut down on fat and calories - Use these steps to choose a goal. Talk with your health care provider and your dietitian about your goal and how to reach it.\n \nTo find your weight loss goal for losing about 5 to 7 percent of your weight, find the weight closest to yours on the chart below.

By making wise food choices, you can help control your body weight, blood glucose, blood pressure, and cholesterol.\n \n- Keep track of what you eat and drink. People who keep track are more successful in losing weight. You can use the Daily Food and Drink Tracker to write down what you eat and drink. - Take a look at the serving sizes of the foods you eat. Reduce serving sizes of main courses, meat, desserts, and other foods high in fat. Increase the amount of fruits and vegetables at every meal. Below is a chart for choosing sensible serving sizes using your hand as a measuring guide. Because your hand is proportioned to the rest of your body, it can be used to measure a healthy serving size for your body. Remember, the chart is only a guide. Choose your serving sizes and foods wisely. - Limit your fat intake to about 25 percent of your total calories. Your health care provider or dietitian can help you figure out how many grams of fat to have every day. You can check food labels for fat content. For example, if your food choices add up to about 2,000 calories a day, try to eat no more than 56 grams of fat. See Ways to Lower The Amount of Fat in Your Meals and Snacks. - Cut down on calories by eating smaller servings and by cutting back on fat. People in the DPP lifestyle change group lowered their daily calorie total by an average of about 450 calories. Your health care provider or dietitian can work with you to develop a meal plan that helps you lose weight. - Choose healthy commodity foods (items provided by the government to help people consume a nutritious diet), including those lower in fat. - When you meet your goal, reward yourself with something special, like a new outfit or a movie.\n \nChoose Sensible Serving Sizes\n \nAmount of food Types of food Size of one serving (the same size as:) 3 ounces meat, chicken, turkey, or fish the palm of a hand or a deck of cards 1 cup cooked vegetables salads casseroles or stews, such as chili with beans milk an average-sized fist 1\/2 cup fruit or fruit juice starchy vegetables, such as potatoes or corn pinto beans and other dried beans rice or noodles cereal half of an average-sized fist 1 ounce snack food one handful 1 Tablespoon salad dressing the tip of a thumb 1 teaspoon margarine a fingertip\n \n\n \nWays to Lower The Amount of Fat in Your Meals and Snacks\n \n- Choose lower-fat foods. Example: Instead of sunflower seeds (20 grams of fat), choose pretzels (1 gram). Savings: 19 grams. - Use low-fat versions of foods. Example: Instead of regular margarine (5 grams of fat), use low-fat margarine (2 grams). Savings: 3 grams. - Use low-fat seasonings. Example: Instead of putting butter and sour cream on your baked potato (20 grams of fat), have salsa (0 grams). Savings: 20 grams. - Cook with less fat. Example: Instead of making fried chicken (31 grams of fat), roast or grill the chicken (9 grams). Savings: 22 grams.\n \nRemember that low-fat or fat-free products still contain calories. Be careful about how much you eat. In fact, some low-fat or fat-free products are high in calories. Check the food label\n \nBe Physically Active Every Day\n \n- Keep track of what you do for exercise and how long you do it. Use the Daily Physical Activity Tracker to keep track of your physical activity. - Aim for at least 30 minutes of physical activity a day most days of the week. - Incorporate physical activity into plans with family and friends. Set a good example for your children. Play softball on weekends. Go on a family hike. - Be active every day. For example, walk to the store, clean the house, or work in the garden, rather than watch TV.\n \nGetting Started on a Walking Routine\n \nWalking is a great way to be physically active. Before you get started, talk with your health care provider about whether it's OK for you to walk for exercise. Then get comfortable shoes that provide good support. You can use the Daily Physical Activity Tracker to start your routine gradually. Try to walk at least 5 times a week. Build up little by little to 30 minutes a day of brisk walking.\n \nMy Walking Program\n \nWeek number Warm-up time (minutes) Walk slowly Fast walk time (minutes) Walk briskly Cool-down time (minutes) Walk slowly Total (minutes) 1 5 5 5 15 2 5 8 5 18 3 5 11 5 21 4 5 14 5 24 5 5 17 5 27 6 5 20 5 30 7 5 23 5 33 8 5 26 5 36 9+ 5 30 5 40\n \nTake Your Prescribed Medicines\n \n\n \n\n \nDaily Food and Drink Tracker\n \nUse the Daily Food and Drink Tracker to keep track of everything you eat and drink.

Both tests look at one specific waste product, called blood urea nitrogen (BUN), as an indicator for the overall level of waste products in your system. For more information about these measurements, see the NIDDK fact sheet Hemodialysis Dose and Adequacy."} {"_id":"7ae59db2-6a06-438b-b2fe-864b6c683ad9","text":"Your kidneys do much more than remove wastes and extra fluid. They also make hormones and balance chemicals in your system. When your kidneys stop working, you may have problems with anemia and conditions that affect your bones, nerves, and skin. Some of the more common conditions caused by kidney failure are extreme tiredness, bone problems, joint problems, itching, and \"restless legs.\" Restless legs will keep you awake as you feel them twitching and jumping.\n \nAnemia and Erythropoietin (EPO)\n \nAnemia is a condition in which the volume of red blood cells is low. Red blood cells carry oxygen to cells throughout the body. Without oxygen, cells can't use the energy from food, so someone with anemia may tire easily and look pale. Anemia can also contribute to heart problems.\n \nAnemia is common in people with kidney disease because the kidneys produce the hormone erythropoietin, or EPO, which stimulates the bone marrow to produce red blood cells. Diseased kidneys often don't make enough EPO, and so the bone marrow makes fewer red blood cells. EPO is available commercially and is commonly given to patients on dialysis.\n \nFor more information about the causes of and treatments for anemia in kidney failure, see the NIDDK fact sheet Anemia in Chronic Kidney Disease.\n \nRenal Osteodystrophy\n \nThe term \"renal\" describes things related to the kidneys. Renal osteodystrophy, or bone disease of kidney failure, affects 90 percent of dialysis patients. It causes bones to become thin and weak or formed incorrectly and affects both children and adults. Symptoms can be seen in growing children with kidney disease even before they start dialysis. Older patients and women who have gone through menopause are at greater risk for this disease.\n \nFor more information about the causes of this bone disease and its treatment in dialysis patients, see the NIDDK fact sheet Chronic Kidney Disease-Mineral and Bone Disorder.\n \nItching (Pruritus)\n \nMany people treated with hemodialysis complain of itchy skin, which is often worse during or just after treatment. Itching is common even in people who don't have kidney disease; in kidney failure, however, itching can be made worse by wastes in the bloodstream that current dialyzer membranes can't remove from the blood.\n \nThe problem can also be related to high levels of parathyroid hormone (PTH). Some people have found dramatic relief after having their parathyroid glands removed. The four parathyroid glands sit on the outer surface of the thyroid gland, which is located on the windpipe in the base of your neck, just above the collarbone. The parathyroid glands help control the levels of calcium and phosphorus in the blood.\n \nBut a cure for itching that works for everyone has not been found. Phosphate binders seem to help some people; these medications act like sponges to soak up, or bind, phosphorus while it is in the stomach. Others find relief after exposure to ultraviolet light. Still others improve with EPO shots. A few antihistamines (Benadryl, Atarax, Vistaril) have been found to help; also, capsaicin cream applied to the skin may relieve itching by deadening nerve impulses. In any case, taking care of dry skin is important. Applying creams with lanolin or camphor may help.\n \nSleep Disorders\n \nPatients on dialysis often have insomnia, and some people have a specific problem called the sleep apnea syndrome, which is often signaled by snoring and breaks in snoring. Episodes of apnea are actually breaks in breathing during sleep. Over time, these sleep disturbances can lead to \"day-night reversal\" (insomnia at night, sleepiness during the day), headache, depression, and decreased alertness. The apnea may be related to the effects of advanced kidney failure on the control of breathing. Treatments that work with people who have sleep apnea, whether they have kidney failure or not, include losing weight, changing sleeping position, and wearing a mask that gently pumps air continuously into the nose (nasal continuous positive airway pressure, or CPAP).\n \nMany people on dialysis have trouble sleeping at night because of aching, uncomfortable, jittery, or \"restless\" legs. You may feel a strong impulse to kick or thrash your legs. Kicking may occur during sleep and disturb a bed partner throughout the night. The causes of restless legs may include nerve damage or chemical imbalances.\n \nModerate exercise during the day may help, but exercising a few hours before bedtime can make it worse. People with restless leg syndrome should reduce or avoid caffeine, alcohol, and tobacco; some people also find relief with massages or warm baths. A class of drugs called benzodiazepines, often used to treat insomnia or anxiety, may help as well. These prescription drugs include Klonopin, Librium, Valium, and Halcion. A newer and sometimes more effective therapy is levodopa (Sinemet), a drug used to treat Parkinson's disease.\n \nSleep disorders may seem unimportant, but they can impair your quality of life. Don't hesitate to raise these problems with your nurse, doctor, or social worker.\n \nAmyloidosis\n \nDialysis-related amyloidosis (DRA) is common in people who have been on dialysis for more than 5 years. DRA develops when proteins in the blood deposit on joints and tendons, causing pain, stiffness, and fluid in the joints, as is the case with arthritis. Working kidneys filter out these proteins, but dialysis filters are not as effective.

The digestive tract breaks down carbohydratessugars and starches found in many foodsinto glucose. Glucose is a form of sugar that enters the bloodstream. With the help of insulin, cells throughout the body absorb glucose and use it for energy.\n \nInsulin's Role in Blood Glucose Control\n \nWhen blood glucose levels rise after a meal, the pancreas releases insulin into the blood. Insulin and glucose then travel in the blood to cells throughout the body.\n \n- Insulin helps muscle, fat, and liver cells absorb glucose from the bloodstream, lowering blood glucose levels. - Insulin stimulates the liver and muscle tissue to store excess glucose. The stored form of glucose is called glycogen. - Insulin also lowers blood glucose levels by reducing glucose production in the liver.\n \nIn a healthy person, these functions allow blood glucose and insulin levels to remain in the normal range."} {"_id":"4b19f115-82da-40af-8fd8-f1ad94bbf9be","text":"Insulin resistance is a condition in which the body produces insulin but does not use it effectively.

Scientists used to think that fat tissue functioned solely as energy storage. However, studies have shown that belly fat produces hormones and other substances that can cause serious health problems such as insulin resistance, high blood pressure, imbalanced cholesterol, and cardiovascular disease (CVD).\n \nBelly fat plays a part in developing chronic, or long-lasting, inflammation in the body. Chronic inflammation can damage the body over time, without any signs or symptoms. Scientists have found that complex interactions in fat tissue draw immune cells to the area and trigger low-level chronic inflammation. This inflammation can contribute to the development of insulin resistance, type 2 diabetes, and CVD. Studies show that losing the weight can reduce insulin resistance and prevent or delay type 2 diabetes.\n \nPhysical Inactivity\n \nMany studies have shown that physical inactivity is associated with insulin resistance, often leading to type 2 diabetes. In the body, more glucose is used by muscle than other tissues. Normally, active muscles burn their stored glucose for energy and refill their reserves with glucose taken from the bloodstream, keeping blood glucose levels in balance.\n \nStudies show that after exercising, muscles become more sensitive to insulin, reversing insulin resistance and lowering blood glucose levels. Exercise also helps muscles absorb more glucose without the need for insulin. The more muscle a body has, the more glucose it can burn to control blood glucose levels.\n \nOther Causes\n \nOther causes of insulin resistance may include ethnicity; certain diseases; hormones; steroid use; some medications; older age; sleep problems, especially sleep apnea; and cigarette smoking.\n \n\n \nDoes sleep matter? Yes. Studies show that untreated sleep problems, especially sleep apnea, can increase the risk of obesity, insulin resistance, and type 2 diabetes. Night shift workers may also be at increased risk for these problems. Sleep apnea is a common disorder in which a person's breathing is interrupted during sleep. People may often move out of deep sleep and into light sleep when their breathing pauses or becomes shallow. This results in poor sleep quality that causes problem sleepiness, or excessive tiredness, during the day. Many people aren't aware of their symptoms and aren't diagnosed. People who think they might have sleep problems should talk with their health care provider.

Insulin resistance can be assessed by measuring the level of insulin in the blood.\n \nHowever, the test that most accurately measures insulin resistance, called the euglycemic clamp, is too costly and complicated to be used in most health care providers' offices. The clamp is a research tool used by scientists to learn more about glucose metabolism. Research has shown that if blood tests indicate prediabetes, insulin resistance most likely is present.\n \nBlood Tests for Prediabetes\n \nAll blood tests involve drawing blood at a health care provider's office or commercial facility and sending the sample to a lab for analysis. Lab analysis of blood is needed to ensure test results are accurate. Glucose measuring devices used in a health care provider's office, such as finger-stick devices, are not accurate enough for diagnosis but may be used as a quick indicator of high blood glucose.\n \nPrediabetes can be detected with one of the following blood tests:\n \n- the A1C test - the fasting plasma glucose (FPG) test - the oral glucose tolerance test (OGTT)\n \nA1C test. Sometimes called hemoglobin A1c, HbA1c, or glycohemoglobin test, this test reflects average blood glucose levels over the past 3 months. This test is the most reliable test for prediabetes, but it is not as sensitive as the other tests. In some individuals, it may miss prediabetes that could be caught by glucose tests.\n \nAlthough some health care providers can quickly measure A1C in their office, that type of measurementcalled a point-of-care testis not considered reliable for diagnosis. For diagnosis of prediabetes, the A1C test should be analyzed in a laboratory using a method that is certified by the NGSP.\n \nThe A1C test can be unreliable for diagnosing prediabetes in people with certain conditions that are known to interfere with the results. Interference should be suspected when A1C results seem very different from the results of a blood glucose test. People of African, Mediterranean, or Southeast Asian descent, or people with family members with sickle cell anemia or a thalassemia, are particularly at risk of interference.

Experts encourage people to slowly adopt healthy eating habits that they can maintain, rather than trying extreme weight-loss solutions. People may need to get help from a dietitian or join a weight-loss program for support.\n \nIn general, people should lose weight by choosing healthy foods, controlling portions, eating less fat, and increasing physical activity. People are better able to lose weight and keep it off when they learn how to adapt their favorite foods to a healthy eating plan.\n \nThe DASH (Dietary Approaches to Stop Hypertension) eating plan, developed by the NIH, has been shown to be effective in decreasing insulin resistance when combined with weight loss and physical activity. More information on DASH is available at www.nhlbi.nih.gov\/health\/health-topics\/topics\/dash.\n \nThe U.S. Dietary Guidelines for Americans also offers healthy eating advice and tools for changing eating habits at www.choosemyplate.gov.\n \nDietary Supplements\n \nVitamin D studies show a link between people's ability to maintain healthy blood glucose levels and having enough vitamin D in their blood. However, studies to determine the proper vitamin D levels for preventing diabetes are ongoing; no special recommendations have been made about vitamin D levels or supplements for people with prediabetes.\n \nCurrently, the Institute of Medicine (IOM), the agency that recommends supplementation levels based on current science, provides the following guidelines for daily vitamin D intake:\n \n- People ages 1 to 70 years may require 600 International Units (IUs). - People ages 71 and older may require as much as 800 IUs.\n \nThe IOM also recommended that no more than 4,000 IUs of vitamin D be taken per day.\n \nTo help ensure coordinated and safe care, people should discuss use of complementary and alternative medicine practices, including the use of dietary supplements, with their health care provider.\n \nMore information about using dietary supplements to help with diabetes is provided in the NIDDK health topic, Complementary and Alternative Medical Therapies for Diabetes.\n \n\n \nPhysical Activity\n \nRegular physical activity tackles several risk factors at once.

Many chose brisk walking as their physical activity.\n \nMost people should aim for at least 30 minutes of exercise most days of the week. For best results, people should do both aerobic activities, which use large muscle groups and make the heart beat faster, and muscle strengthening activities.\n \nAerobic activities include brisk walking, climbing stairs, swimming, dancing, and other activities that increase the heart rate.\n \nMuscle strengthening activities include lifting weights and doing sit-ups or push-ups.\n \nPeople who haven't been physically active recently should talk with their health care provider about which activities are best for them and have a checkup before starting an exercise program.\n \nNot Smoking\n \nThose who smoke should quit.

People at high risk should ask their health care provider if they should take metformin to prevent type 2 diabetes.\n \nSeveral medications have been shown to reduce type 2 diabetes risk to varying degrees, but the only medication recommended by the ADA for type 2 diabetes prevention is metformin. Other medications that have delayed diabetes have side effects or haven't shown long-lasting benefits. No medication, including metformin, is approved by the U.S. Food and Drug Administration to treat insulin resistance or prediabetes or to prevent type 2 diabetes."} {"_id":"661d6fea-86fd-4e16-aab3-8688aa66d269","text":"- Insulin is a hormone that helps cells throughout the body absorb glucose and use it for energy.

Amyloid deposits damage the kidneys and make it harder for them to filter wastes and break down proteins. When the kidneys become too damaged, they may no longer be able to function well enough to maintain health, resulting in kidney failure. Kidney failure can lead to problems such as high blood pressure, bone disease, and anemiaa condition in which the body has fewer red blood cells than normal.\n \nDialysis-related Amyloidosis\n \nPeople who suffer from kidney failure and have been on long-term dialysis may develop dialysis-related amyloidosis. This type of amyloidosis occurs when a certain protein, called beta-2 microglobulin, builds up in the blood because dialysis does not remove it completely. The two types of dialysis are\n \n- hemodialysis. Hemodialysis uses a special filter called a dialyzer to remove wastes and extra fluid from the blood. - peritoneal dialysis. Peritoneal dialysis uses the lining of the abdominal cavitythe space in the body that holds organs such as the stomach, intestines, and liverto filter the blood.\n \nDialysis-related amyloidosis is a complication of kidney failure because neither hemodialysis nor peritoneal dialysis effectively filters beta-2 microglobulin from the blood. As a result, elevated amounts of beta-2 microglobulin remain in the blood. Dialysis-related amyloidosis is relatively common in people with kidney failure, especially adults older than 60 years of age, who have been on dialysis for more than 5 years.1\n \nMore information is provided in the NIDDK health topics:\n \n- Treatment Methods for Kidney Failure: Hemodialysis - Treatment Methods for Kidney Failure: Peritoneal Dialysis"} {"_id":"89925672-41b8-466b-bcb3-2ad1415d8e23","text":"The most common sign of primary amyloidosis of the kidneys is nephrotic syndromea collection of signs that indicate kidney damage.

Diverticulosis and diverticular disease were first noticed in the United States in the early 1900s, around the time processed foods were introduced into the American diet. Consumption of processed foods greatly reduced Americans fiber intake. Diverticulosis and diverticular disease are common in Western and industrialized countriesparticularly the United States, England, and Australiawhere low-fiber diets are common. The condition is rare in Asia and Africa, where most people eat high-fiber diets.1 Two large studies also indicate that a low-fiber diet may increase the chance of developing diverticular disease.2\n \nHowever, a recent study found that a low-fiber diet was not associated with diverticulosis and that a high-fiber diet and more frequent bowel movements may be linked to an increased rather than decreased chance of diverticula.3\n \nOther studies have focused on the role of decreased levels of the neurotransmitter serotonin in causing decreased relaxation and increased spasms of the colon muscle. A neurotransmitter is a chemical that helps brain cells communicate with nerve cells. However, more studies are needed in this area.\n \nStudies have also found links between diverticular disease and obesity, lack of exercise, smoking, and certain medications including nonsteroidal anti-inflammatory drugs, such as aspirin, and steroids.3\n \nScientists agree that with diverticulitis, inflammation may begin when bacteria or stool get caught in a diverticulum. In the colon, inflammation also may be caused by a decrease in healthy bacteria and an increase in disease-causing bacteria. This change in the bacteria may permit chronic inflammation to develop in the colon.\n \n\n \nWhat is fiber? Fiber is a substance in foods that comes from plants. Fiber helps soften stool so it moves smoothly through the colon and is easier to pass. Soluble fiber dissolves in water and is found in beans, fruit, and oat products. Insoluble fiber does not dissolve in water and is found in whole-grain products and vegetables. Both kinds of fiber help prevent constipation. Constipation is a condition in which an adult has fewer than three bowel movements a week or has bowel movements with stools that are hard, dry, and small, making them painful or difficult to pass. High-fiber foods also have many benefits in preventing and controlling chronic diseases, such as cardiovascular disease, obesity, diabetes, and cancer.2"} {"_id":"bc9c763e-258b-4eba-98b0-96d2316a7307","text":"Fiber is a substance in foods that comes from plants.

A rectal exam is performed in the health care providers office; anesthesia is not needed. To perform the exam, the health care provider asks the person to bend over a table or lie on one side while holding the knees close to the chest. The health care provider slides a gloved, lubricated finger into the rectum. The exam is used to check for pain, bleeding, or a blockage in the intestine.\n \nThe health care provider may schedule one or more of the following tests:\n \n- Blood test. A blood test involves drawing a persons blood at a health care providers office, a commercial facility, or a hospital and sending the sample to a lab for analysis. The blood test can show the presence of inflammation or anemiaa condition in which red blood cells are fewer or smaller than normal, which prevents the bodys cells from getting enough oxygen. - Computerized tomography (CT) scan. A CT scan of the colon is the most common test used to diagnose diverticular disease. CT scans use a combination of x rays and computer technology to create three-dimensional (3D) images. For a CT scan, the person may be given a solution to drink and an injection of a special dye, called contrast medium. CT scans require the person to lie on a table that slides into a tunnel-shaped device where the x rays are taken. The procedure is performed in an outpatient center or a hospital by an x-ray technician, and the images are interpreted by a radiologista doctor who specializes in medical imaging. Anesthesia is not needed. CT scans can detect diverticulosis and confirm the diagnosis of diverticulitis. - Lower gastrointestinal (GI) series. A lower GI series is an x-ray exam that is used to look at the large intestine. The test is performed at a hospital or an outpatient center by an x-ray technician, and the images are interpreted by a radiologist. Anesthesia is not needed. The health care provider may provide written bowel prep instructions to follow at home before the test. The person may be asked to follow a clear liquid diet for 1 to 3 days before the procedure. A laxative or enema may be used before the test. A laxative is medication that loosens stool and increases bowel movements. An enema involves flushing water or laxative into the rectum using a special squirt bottle. These medications cause diarrhea, so the person should stay close to a bathroom during the bowel prep. - For the test, the person will lie on a table while the radiologist inserts a flexible tube into the persons anus. The colon is filled with barium, making signs of diverticular disease show up more clearly on x rays. - For several days, traces of barium in the large intestine can cause stools to be white or light colored. Enemas and repeated bowel movements may cause anal soreness. A health care provider will provide specific instructions about eating and drinking after the test. - Colonoscopy. The test is performed at a hospital or an outpatient center by a gastroenterologist. Before the test, the persons health care provider will provide written bowel prep instructions to follow at home. The person may need to follow a clear liquid diet for 1 to 3 days before the test. The person may also need to take laxatives and enemas the evening before the test. - In most cases, light anesthesia, and possibly pain medication, helps people relax for the test. The person will lie on a table while the gastroenterologist inserts a flexible tube into the anus. A small camera on the tube sends a video image of the intestinal lining to a computer screen. The test can show diverticulosis and diverticular disease. - Cramping or bloating may occur during the first hour after the test. Driving is not permitted for 24 hours after the test to allow the anesthesia time to wear off. Before the appointment, people should make plans for a ride home. Full recovery is expected by the next day, and people should be able to go back to their normal diet."} {"_id":"403a6840-35b9-44fe-9b28-b9b34af5eb8f","text":"A health care provider may treat the symptoms of diverticulosis with a high-fiber diet or fiber supplements, medications, and possibly probiotics. Treatment for diverticular disease varies, depending on whether a person has diverticulitis or diverticular bleeding.\n \nDiverticulosis\n \nHigh-fiber diet. Studies have shown that a high-fiber diet can help prevent diverticular disease in people who already have diverticulosis.2 A health care provider may recommend a slow increase in dietary fiber to minimize gas and abdominal discomfort. For more information about fiber-rich foods, see Eating, Diet, and Nutrition.\n \nFiber supplements. A health care provider may recommend taking a fiber product such as methylcellulose (Citrucel) or psyllium (Metamucil) one to three times a day. These products are available as powders, pills, or wafers and provide 0.5 to 3.5 grams of fiber per dose. Fiber products should be taken with at least 8 ounces of water.\n \nMedications. A number of studies suggest the medication mesalazine (Asacol), given either continuously or in cycles, may be effective at reducing abdominal pain and GI symptoms of diverticulosis. Research has also shown that combining mesalazine with the antibiotic rifaximin (Xifaxan) can be significantly more effective than using rifaximin alone to improve a persons symptoms and maintain periods of remission, which means being free of symptoms.4\n \nProbiotics. Although more research is needed, probiotics may help treat the symptoms of diverticulosis, prevent the onset of diverticulitis, and reduce the chance of recurrent symptoms. Probiotics are live bacteria, like those normally found in the GI tract. Probiotics can be found in dietary supplementsin capsules, tablets, and powdersand in some foods, such as yogurt.\n \nTo help ensure coordinated and safe care, people should discuss their use of complementary and alternative medical practices, including their use of dietary supplements and probiotics, with their health care provider. Read more at www.nccam.nih.gov\/health\/probiotics.\n \nTips for talking with health care providers are available at www.nccam.nih.gov\/timetotalk.\n \nDiverticular Bleeding\n \nDiverticular bleeding is rare. Bleeding can be severe; however, it may stop by itself and not require treatment. A person who has bleeding from the rectumeven a small amountshould see a health care provider right away.\n \nTo treat the bleeding, a colonoscopy may be performed to identify the location of and stop the bleeding. A CT scan or angiogram also may be used to identify the site of the bleeding. A traditional angiogram is a special kind of x ray in which a thin, flexible tube called a catheter is threaded through a large artery, often from the groin, to the area of bleeding. Contrast medium is injected through the catheter so the artery shows up more clearly on the x ray. The procedure is performed in a hospital or an outpatient center by an x-ray technician, and the images are interpreted by a radiologist. Anesthesia is not needed, though a sedative may be given to lessen anxiety during the procedure.\n \nIf the bleeding does not stop, abdominal surgery with a colon resection may be necessary. In a colon resection, the surgeon removes the affected part of the colon and joins the remaining ends of the colon together; general anesthesia is used. A blood transfusion may be needed if the person has lost a significant amount of blood.\n \nDiverticulitis\n \nDiverticulitis with mild symptoms and no complications usually requires a person to rest, take oral antibiotics, and be on a liquid diet for a period of time. If symptoms ease after a few days, the health care provider will recommend gradually adding solid foods back into the diet.\n \nSevere cases of diverticulitis with acute pain and complications will likely require a hospital stay. Most cases of severe diverticulitis are treated with intravenous (IV) antibiotics and a few days without food or drink to help the colon rest. If the period without food or drink is longer, the person may be given parenteral nutritiona method of providing an IV liquid food mixture through a special tube in the chest. The mixture contains proteins, carbohydrates, fats, vitamins, and minerals."} {"_id":"ad9fa3f9-bbb1-4934-bf02-1c4be98046fa","text":"Diverticulitis can attack suddenly and cause complications, such as\n \n- an abscessa painful, swollen, pus-filled area just outside the colon wallcaused by infection - a perforationa small tear or hole in the diverticula - peritonitisinflammation of tissues inside the abdomen from pus and stool that leak through a perforation - a fistulaan abnormal passage, or tunnel, between two organs, or between an organ and the outside of the body - intestinal obstructionpartial or total blockage of movement of food or stool through the intestines\n \nThese complications need to be treated to prevent them from getting worse and causing serious illness. In some cases, surgery may be needed.\n \nAbscess, perforation, and peritonitis. Antibiotic treatment of diverticulitis usually prevents or treats an abscess. If the abscess is large or does not clear up with antibiotics, it may need to be drained. After giving the person numbing medication, a radiologist inserts a needle through the skin to the abscess and then drains the fluid through a catheter. The procedure is usually guided by an abdominal ultrasound or a CT scan. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure.\n \nA person with a perforation usually needs surgery to repair the tear or hole. Sometimes, a person needs surgery to remove a small part of the intestine if the perforation cannot be repaired.\n \nA person with peritonitis may be extremely ill, with nausea, vomiting, fever, and severe abdominal tenderness. This condition requires immediate surgery to clean the abdominal cavity and possibly a colon resection at a later date after a course of antibiotics. A blood transfusion may be needed if the person has lost a significant amount of blood. Without prompt treatment, peritonitis can be fatal.\n \nFistula. Diverticulitis-related infection may lead to one or more fistulas. Fistulas usually form between the colon and the bladder, small intestine, or skin. The most common type of fistula occurs between the colon and the bladder. Fistulas can be corrected with a colon resection and removal of the fistula.\n \nIntestinal obstruction. Diverticulitis-related inflammation or scarring caused by past inflammation may lead to intestinal obstruction. If the intestine is completely blocked, emergency surgery is necessary, with possible colon resection. Partial blockage is not an emergency, so the surgery or other procedures to correct it can be scheduled.\n \nWhen urgent surgery with colon resection is necessary for diverticulitis, two procedures may be needed because it is not safe to rejoin the colon right away. During the colon resection, the surgeon performs a temporary colostomy, creating an opening, or stoma, in the abdomen. The end of the colon is connected to the opening to allow normal eating while healing occurs. Stool is collected in a pouch attached to the stoma on the abdominal wall. In the second surgery, several months later, the surgeon rejoins the ends of the colon and closes the stoma."} {"_id":"b906a1fc-3a28-4c08-8f56-bd3f41fb934f","text":"The Dietary Guidelines for Americans, 2010, recommends a dietary fiber intake of 14 grams per 1,000 calories consumed.

In some people with primary intestinal pseudo-obstruction, mutations, or changes, in genestraits passed from parent to childcause the condition. However, health care providers do not typically order genetic testing for an intestinal pseudo-obstruction, as they dont commonly recognize gene mutations as a cause.\n \nSome people have duplications or deletions of genetic material in the FLNA gene. Researchers believe that these genetic changes may impair the function of a protein, causing problems with the nerve cells in the intestines.1 As a result, the nerves cannot work with the intestinal muscles to produce normal contractions that move food, fluid, and air through the digestive tract. Also, these genetic changes may account for some of the other signs and symptoms that can occur with intestinal pseudo-obstruction, such as bladder symptoms and muscle weakness.\n \nA condition called mitochondrial neurogastrointestinal encephalopathy may also cause primary intestinal pseudo-obstruction.

A health care provider will perform a physical exam; take a complete medical history, imaging studies, and a biopsy; and perform blood tests. A health care provider may order other tests to confirm the diagnosis. The health care provider also will look for the cause of the condition, such as an underlying illness.\n \nIntestinal pseudo-obstruction can be difficult to diagnose, especially primary intestinal pseudo-obstruction. As a result, a correct diagnosis may take a long time.\n \nPhysical Exam\n \nA physical exam is one of the first things a health care provider may do to help diagnose intestinal pseudo-obstruction. During a physical exam, a health care provider usually\n \n- examines a persons body - uses a stethoscope to listen to bodily sounds - taps on specific areas of the persons body\n \nMedical History\n \nThe health care provider will ask a person to provide a medical and family history to help diagnose intestinal pseudo-obstruction.\n \nImaging Studies\n \nA health care provider may order the following imaging studies:\n \n- Abdominal x ray. An x ray is a picture recorded on film or a computer that a technician takes using low-level radiation. The amount of radiation used is small. An x-ray technician takes the x ray at a hospital or an outpatient center, and a radiologista doctor who specializes in medical imaginginterprets the images. A person does not need anesthesia. The person will lie on a table or stand during the x ray. The technician positions the x-ray machine over the abdominal area. The person will hold his or her breath as the technician takes the picture so that the picture will not be blurry. The technician may ask the person to change position for additional pictures. An x ray of the abdominal area will show whether symptoms are due to an intestinal blockage. - Upper GI series. A health care provider may order an upper GI series to look at the small intestine. An x-ray technician performs the test at a hospital or an outpatient center, and a radiologist interprets the images; the health care provider may give infants and children anesthesia. A person should not eat or drink for 8 hours before the procedure, if possible. During the procedure, the person will stand or sit in front of an x-ray machine and drink barium, a chalky liquid. Infants lie on a table and the technician will give them barium through a tiny tube placed in the nose that runs into the stomach. Barium coats the lining of the small intestine, making signs of obstruction show up more clearly on x rays. A person may experience bloating and nausea for a short time after the test. Barium liquid in the GI tract causes stools to be white or light colored for several days or longer in people with intestinal pseudo-obstruction. A health care provider will give the person specific instructions about eating and drinking after the test. - Lower GI series. A health care provider may order a lower GI series, an x-ray exam to look at the large intestine. An x-ray technician performs the test at a hospital or an outpatient center, and a radiologist interprets the images. A person does not need anesthesia. The health care provider may provide written bowel prep instructions to follow at home before the test. The health care provider may ask the person to follow a clear liquid diet for 1 to 3 days before the procedure. A person may need to use a laxative or an enema before the test. A laxative is medication that loosens stool and increases bowel movements. An enema involves flushing water or laxative into the anus using a special squirt bottle.

For a CT scan, a health care provider may give the person a solution to drink and an injection of a special dye, called contrast medium. CT scans require the person to lie on a table that slides into a tunnel-shaped device where the technician takes the x rays. CT scans can show both the internal and external intestinal wall. The health care provider may give children a sedative to help them fall asleep for the test. - Upper GI endoscopy. This procedure involves using an endoscopea small, flexible tube with a lightto see the upper GI tract, which includes the esophagus, stomach, and duodenum. A gastroenterologist performs the test at a hospital or an outpatient center. The gastroenterologist carefully feeds the endoscope down the esophagus and into the stomach and duodenum. A small camera mounted on the endoscope transmits a video image to a monitor, allowing close examination of the intestinal lining. A health care provider may give a person a liquid anesthetic to gargle or may spray anesthetic on the back of the persons throat. A health care provider will place an intravenous (IV) needle in a vein in the arm to administer sedation. Sedatives help patients stay relaxed and comfortable. This test can show blockages or other conditions in the upper small intestine. A gastroenterologist may obtain a biopsy of the lining of the small intestine during an upper GI endoscopy.\n \nBiopsy\n \nA gastroenterologist can obtain a biopsy of the intestinal wall during endoscopy or during surgery, if the person has surgery for intestinal pseudo-obstruction and the cause is unknown. If the health care provider needs to examine the nerves in the intestinal wall, a deeper biopsy, which a gastroenterologist can typically obtain only during surgery, is necessary.\n \nA biopsy is a procedure that involves taking a piece of the intestinal wall tissue for examination with a microscope. A health care provider performs the biopsy in a hospital and uses light sedation and local anesthetic; the health care provider uses general anesthesia if performing the biopsy during surgery. A pathologista doctor who specializes in diagnosing diseasesexamines the intestinal tissue in a lab. Diagnosing problems in the nerve pathways of the intestinal tissue requires special techniques that are not widely available.\n \nA health care provider can also use a biopsy obtained during endoscopy to rule out celiac disease. Celiac disease is an autoimmune disorder in which people cannot tolerate gluten because it damages the lining of their small intestine and prevents absorption of nutrients. Gluten is a protein found in wheat, rye, and barley and in products such as vitamin and nutrient supplements, lip balms, and certain medications.\n \nBlood Tests\n \nA blood test involves drawing blood at a health care providers office or a commercial facility and sending the sample to a lab for analysis. The blood test can show the presence of other diseases or conditions that may be causing a persons symptoms. The blood test also can show levels of essential vitamins and minerals to help detect malnutrition.\n \nManometry\n \nManometry is a test that measures muscle pressure and movements in the GI tract, such as how well the smooth muscles of the stomach and small intestine contract and relax. A gastroenterologist performs the test at a hospital or an outpatient center. While the person is under sedation, a health care provider places a thin tube, or manometry tube, into the stomach and moves it down into the small intestine. A gastroenterologist may use an endoscope to place this tube. A health care provider will move the person to a manometry room and connect the manometry tube to a computer. When the person wakes up from sedation, the computer records the pressure inside the intestine while the person is fasting and after the person has eaten a meal. Manometry can confirm the diagnosis of intestinal pseudo-obstruction and show the extent of the condition.\n \nGastric Emptying Tests\n \nGastric emptying tests can show if a disorder called gastroparesis is causing a persons symptoms. People with gastroparesis, which literally refers to a paralyzed stomach, have severely delayed gastric emptying, or the delayed movement of food from the stomach to the small intestine. Some patients with intestinal pseudo-obstruction also have gastroparesis.\n \nTypes of gastric emptying tests include the following:\n \n- Gastric emptying scintigraphy. This test involves eating a bland mealsuch as eggs or an egg substitutethat contains a small amount of radioactive material. A specially trained technician performs the test in a radiology center or hospital, and a radiologist interprets the results; the person does not need anesthesia. An external camera scans the abdomen to show where the radioactive material is located. The radiologist is then able to measure the rate of gastric emptying at 1, 2, 3, and 4 hours after the meal. Normal values depend on the composition of the meal. With some meals, if more than 10 percent of the meal is still in the stomach at 4 hours, a health care provider confirms the diagnosis of gastroparesis. Obtaining scans for 4 hours after the meal is essential. When the technician only obtains scans 1 to 2 hours after the meal, the results are often unreliable. - Breath test. With this test, the person eats a meal containing a small amount of nonradioactive material. Then, the health care provider takes breath samples over a period of several hours to measure the amount of nonradioactive material in the exhaled breath. The results allow the health care provider to calculate how fast the stomach is emptying. - SmartPill. The SmartPill is a small electronic device in capsule form. The SmartPill test is available at specialized outpatient centers. The person swallows the device so that it can move through the entire digestive tract and send information to a cell-phone-sized receiver worn around the persons waist or neck. The recorded information provides details about how quickly food travels through each part of the digestive tract."} {"_id":"3d72d1a4-dff0-4b07-9717-eaaac07422c1","text":"A health care provider will treat intestinal pseudo-obstruction with nutritional support, medications, and, in some cases, decompression. Rarely, a person will need surgery. If an illness, a medication, or both cause intestinal pseudo-obstruction, a health care provider will treat the underlying illness, stop the medication, or do both.\n \nNutritional Support\n \nPeople with intestinal pseudo-obstruction often need nutritional support to prevent malnutrition and weight loss. Enteral nutrition provides liquid food through a feeding tube inserted through the nose into the stomach or placed directly into the stomach or small intestine. A health care provider inserts the feeding tube, sometimes using x ray or endoscopy for guidance, and teaches the person how to care for the tube after returning home. Enteral nutrition is sufficient for most people with intestinal pseudo-obstruction. In a severe case, a person may need IV feeding, also called parenteral nutrition, which provides liquid food through a tube placed in a vein.\n \nEnteral nutrition is possible because the intestinal lining is normal in most people with intestinal pseudo-obstruction. Enteral nutrition is preferred over parenteral nutrition because it has a much lower risk of complications.\n \nMedications\n \nA health care provider prescribes medications to treat the different symptoms and complications of intestinal pseudo-obstruction, such as\n \n- antibiotics to treat bacterial infections - pain medication, which should be used sparingly, if at all, because most pain medications delay intestinal transit - medication to make intestinal muscles contract - antinausea medications - antidiarrheal medications - laxatives\n \nDecompression\n \nA person with acute colonic pseudo-obstruction and a greatly enlarged colon who does not respond to medications may need a procedure, called decompression, to remove gas from the colon. A gastroenterologist can perform the procedure in a hospital or an outpatient center. The gastroenterologist may choose to decompress the colon by using colonoscopy. During colonoscopy, the gastroenterologist inserts a flexible tube into the colon through the anus. A health care provider gives the person a light sedative, and possibly pain medication, to relax. If the person requires long-term decompression, the gastroenterologist also can decompress the colon through a surgical opening in the cecum. In this case, the health care provider gives the person local anesthesia.\n \nSurgery\n \nIn severe cases of intestinal pseudo-obstruction, a person may need surgery to remove part of the intestine. However, surgery should be performed rarely, if at all, because intestinal pseudo-obstruction is a generalized disorder that typically affects the entire intestine. Removing part of the intestine cannot cure the disease.\n \nA surgeona doctor who specializes in surgerywill perform the surgery at a hospital; a person will need general anesthesia. A few highly specialized treatment centers offer small intestine transplantation. A health care provider may recommend small intestine transplantation when all other treatments have failed."} {"_id":"215ee82b-84fe-4631-b5ad-53a84fdc114a","text":"Researchers have not found that eating, diet, and nutrition play a role in causing or preventing intestinal pseudo-obstruction.

The pituitary, a small gland in the brain, makes GH. In acromegaly, the pituitary produces excessive amounts of GH. Usually the excess GH comes from benign, or noncancerous, tumors on the pituitary. These benign tumors are called adenomas.\n \nAcromegaly is most often diagnosed in middle-aged adults, although symptoms can appear at any age. If not treated, acromegaly can result in serious illness and premature death. Acromegaly is treatable in most patients, but because of its slow and often \"sneaky\" onset, it often is not diagnosed early or correctly. The most serious health consequences of acromegaly are type 2 diabetes, high blood pressure, increased risk of cardiovascular disease, and arthritis. Patients with acromegaly are also at increased risk for colon polyps, which may develop into colon cancer if not removed.\n \nWhen GH-producing tumors occur in childhood, the disease that results is called gigantism rather than acromegaly. A child's height is determined by the length of the so-called long bones in the legs. In response to GH, these bones grow in length at the growth platesareas near either end of the bone. Growth plates fuse after puberty, so the excessive GH production in adults does not result in increased height. However, prolonged exposure to excess GH before the growth plates fuse causes increased growth of the long bones and thus increased height. Pediatricians may become concerned about this possibility if a child's growth rate suddenly and markedly increases beyond what would be predicted by previous growth and how tall the child's parents are."} {"_id":"178cc433-cdcc-437e-a6ba-0bd8a423089b","text":"The name acromegaly comes from the Greek words for \"extremities\" and \"enlargement,\" reflecting one of its most common symptomsthe abnormal growth of the hands and feet. Swelling of the hands and feet is often an early feature, with patients noticing a change in ring or shoe size, particularly shoe width. Gradually, bone changes alter the patient's facial features: The brow and lower jaw protrude, the nasal bone enlarges, and the teeth space out.\n \nOvergrowth of bone and cartilage often leads to arthritis. When tissue thickens, it may trap nerves, causing carpal tunnel syndrome, which results in numbness and weakness of the hands. Body organs, including the heart, may enlarge.\n \nOther symptoms of acromegaly include\n \n- joint aches - thick, coarse, oily skin - skin tags - enlarged lips, nose, and tongue - deepening of the voice due to enlarged sinuses and vocal cords - sleep apnea-breaks in breathing during sleep due to obstruction of the airway - excessive sweating and skin odor - fatigue and weakness - headaches - impaired vision - abnormalities of the menstrual cycle and sometimes breast discharge in women - erectile dysfunction in men - decreased libido"} {"_id":"a170c6f5-0d32-4022-a670-eeae0afa511f","text":"Acromegaly is caused by prolonged overproduction of GH by the pituitary gland. The pituitary produces several important hormones that control body functions such as growth and development, reproduction, and metabolism. But hormones never seem to act simply and directly. They usually \"cascade\" or flow in a series, affecting each other's production or release into the bloodstream.\n \nGH is part of a cascade of hormones that, as the name implies, regulates the physical growth of the body. This cascade begins in a part of the brain called the hypothalamus. The hypothalamus makes hormones that regulate the pituitary. One of the hormones in the GH series, or \"axis,\" is growth hormone-releasing hormone (GHRH), which stimulates the pituitary gland to produce GH.\n \nSecretion of GH by the pituitary into the bloodstream stimulates the liver to produce another hormone called insulin-like growth factor I (IGF-I). IGF-I is what actually causes tissue growth in the body. High levels of IGF-I, in turn, signal the pituitary to reduce GH production.\n \nThe hypothalamus makes another hormone called somatostatin, which inhibits GH production and release. Normally, GHRH, somatostatin, GH, and IGF-I levels in the body are tightly regulated by each other and by sleep, exercise, stress, food intake, and blood sugar levels. If the pituitary continues to make GH independent of the normal regulatory mechanisms, the level of IGF-I continues to rise, leading to bone overgrowth and organ enlargement. High levels of IGF-I also cause changes in glucose (sugar) and lipid (fat) metabolism and can lead to diabetes, high blood pressure, and heart disease.\n \nPituitary Tumors\n \nIn more than 95 percent of people with acromegaly, a benign tumor of the pituitary gland, called an adenoma, produces excess GH. Pituitary tumors are labeled either micro- or macro-adenomas, depending on their size. Most GH-secreting tumors are macro-adenomas, meaning they are larger than 1 centimeter. Depending on their location, these larger tumors may compress surrounding brain structures. For example, a tumor growing upward may affect the optic chiasm-where the optic nerves crossleading to visual problems and vision loss. If the tumor grows to the side, it may enter an area of the brain called the cavernous sinus where there are many nerves, potentially damaging them.\n \nCompression of the surrounding normal pituitary tissue can alter production of other hormones. These hormonal shifts can lead to changes in menstruation and breast discharge in women and erectile dysfunction in men. If the tumor affects the part of the pituitary that controls the thyroidanother hormone-producing glandthen thyroid hormones may decrease. Too little thyroid hormone can cause weight gain, fatigue, and hair and skin changes. If the tumor affects the part of the pituitary that controls the adrenal gland, the hormone cortisol may decrease. Too little cortisol can cause weight loss, dizziness, fatigue, low blood pressure, and nausea.\n \nSome GH-secreting tumors may also secrete too much of other pituitary hormones. For example, they may produce prolactin, the hormone that stimulates the mammary glands to produce milk. Rarely, adenomas may produce thyroid-stimulating hormone. Doctors should assess all pituitary hormones in people with acromegaly.\n \nRates of GH production and the aggressiveness of the tumor vary greatly among people with adenomas. Some adenomas grow slowly and symptoms of GH excess are often not noticed for many years. Other adenomas grow more rapidly and invade surrounding brain areas or the venous sinuses, which are located near the pituitary gland. Younger patients tend to have more aggressive tumors. Regardless of size, these tumors are always benign.\n \nMost pituitary tumors develop spontaneously and are not genetically inherited. They are the result of a genetic alteration in a single pituitary cell, which leads to increased cell division and tumor formation. This genetic change, or mutation, is not present at birth, but happens later in life. The mutation occurs in a gene that regulates the transmission of chemical signals within pituitary cells. It permanently switches on the signal that tells the cell to divide and secrete GH. The events within the cell that cause disordered pituitary cell growth and GH oversecretion currently are the subject of intensive research.\n \nNonpituitary Tumors\n \nRarely, acromegaly is caused not by pituitary tumors but by tumors of the pancreas, lungs, and other parts of the brain. These tumors also lead to excess GH, either because they produce GH themselves or, more frequently, because they produce GHRH, the hormone that stimulates the pituitary to make GH. When these non-pituitary tumors are surgically removed, GH levels fall and the symptoms of acromegaly improve.\n \nIn patients with GHRH-producing, non-pituitary tumors, the pituitary still may be enlarged and may be mistaken for a tumor. Physicians should carefully analyze all \"pituitary tumors\" removed from patients with acromegaly so they do not overlook the rare possibility that a tumor elsewhere in the body is causing the disorder."} {"_id":"f1a820e9-cdcc-4409-bc26-ead3b62d6ac1","text":"Small pituitary adenomas are common, affecting about 17 percent of the population.1 However, research suggests most of these tumors do not cause symptoms and rarely produce excess GH.2 Scientists estimate that three to four out of every million people develop acromegaly each year and about 60 out of every million people suffer from the disease at any time.3 Because the clinical diagnosis of acromegaly is often missed, these numbers probably underestimate the frequency of the disease."} {"_id":"70c67bd3-b01d-43dd-89d3-2e9f8b61f968","text":"Blood tests\n \nIf acromegaly is suspected, a doctor must measure the GH level in a persons blood to determine if it is elevated. However, a single measurement of an elevated blood GH level is not enough to diagnose acromegaly: Because GH is secreted by the pituitary in impulses, or spurts, its concentration in the blood can vary widely from minute to minute. At a given moment, a person with acromegaly may have a normal GH level, whereas a GH level in a healthy person may even be five times higher.\n \nMore accurate information is obtained when GH is measured under conditions that normally suppress GH secretion. Health care professionals often use the oral glucose tolerance test to diagnose acromegaly because drinking 75 to 100 grams of glucose solution lowers blood GH levels to less than 1 nanogram per milliliter (ng\/ml) in healthy people. In people with GH overproduction, this suppression does not occur. The oral glucose tolerance test is a highly reliable method for confirming a diagnosis of acromegaly.\n \nPhysicians also can measure IGF-I levels, which increase as GH levels go up, in people with suspected acromegaly. Because IGF-I levels are much more stable than GH levels over the course of the day, they are often a more practical and reliable screening measure. Elevated IGF-I levels almost always indicate acromegaly. However, a pregnant womans IGF-I levels are two to three times higher than normal. In addition, physicians must be aware that IGF-I levels decline with age and may also be abnormally low in people with poorly controlled diabetes or liver or kidney disease.\n \nImaging\n \nAfter acromegaly has been diagnosed by measuring GH or IGF-I levels, a magnetic resonance imaging (MRI) scan of the pituitary is used to locate and detect the size of the tumor causing GH overproduction. MRI is the most sensitive imaging technique, but computerized tomography (CT) scans can be used if the patient should not have MRI. For example, people who have pacemakers or other types of implants containing metal should not have an MRI scan because MRI machines contain powerful magnets.\n \nIf a head scan fails to detect a pituitary tumor, the physician should look for non-pituitary \"ectopic\" tumors in the chest, abdomen, or pelvis as the cause of excess GH. The presence of such tumors usually can be diagnosed by measuring GHRH in the blood and by a CT scan of possible tumor sites.\n \nRarely, a pituitary tumor secreting GH may be too tiny to detect even with a sensitive MRI scan."} {"_id":"2743581d-0ec7-46d3-81e4-870bca8d2e93","text":"Currently, treatment options include surgical removal of the tumor, medical therapy, and radiation therapy of the pituitary.\n \nGoals of treatment are to\n \n- reduce excess hormone production to normal levels - relieve the pressure that the growing pituitary tumor may be exerting on the surrounding brain areas - preserve normal pituitary function or treat hormone deficiencies - improve the symptoms of acromegaly\n \nSurgery\n \nSurgery is the first option recommended for most people with acromegaly, as it is often a rapid and effective treatment. The surgeon reaches the pituitary via an incision through the nose or inside the upper lip and, with special tools, removes the tumor tissue in a procedure called transsphenoidal surgery. This procedure promptly relieves the pressure on the surrounding brain regions and leads to a rapid lowering of GH levels. If the surgery is successful, facial appearance and soft tissue swelling improve within a few days.\n \nSurgery is most successful in patients with blood GH levels below 45 ng\/ml before the operation and with pituitary tumors no larger than 10 millimeters (mm) in diameter. Success depends in large part on the skill and experience of the surgeon, as well as the location of the tumor. Even with the most experienced neurosurgeon, the chance of a cure is small if the tumor has extended into critical brain structures or into the cavernous sinus where surgery could be risky.\n \nThe success rate also depends on what level of GH is defined as a cure. The best measure of surgical success is normalization of GH and IGF-I levels. The overall rate of remission-control of the disease-after surgery ranges from 55 to 80 percent. (See For More Information to locate a board-certified neurosurgeon.)\n \nA possible complication of surgery is damage to the surrounding normal pituitary tissue, which requires lifelong use of pituitary hormone replacement. The part of the pituitary that stores antidiuretic hormonea hormone important in water balancemay be temporarily or, rarely, permanently damaged and the patient may require medical therapy. Other potential problems include cerebrospinal fluid leaks and, rarely, meningitis. Cerebrospinal fluid bathes the brain and can leak from the nose if the incision area doesnt heal well. Meningitis is a bacterial or viral infection of the meninges, the outer covering of the brain.\n \nEven when surgery is successful and hormone levels return to normal, people with acromegaly must be carefully monitored for years for possible recurrence of the disease. More commonly, hormone levels improve, but do not return to normal. Additional treatment, usually medications, may be required.\n \nMedical Therapy\n \nMedical therapy is most often used if surgery does not result in a cure and sometimes to shrink large tumors before surgery. Three medication groups are used to treat acromegaly.\n \nSomatostatin analogs (SSAs) are the first medication group used to treat acromegaly. They shut off GH production and are effective in lowering GH and IGF-I levels in 50 to 70 percent of patients. SSAs also reduce tumor size in around 0 to 50 percent of patients but only to a modest degree. Several studies have shown that SSAs are safe and effective for long-term treatment and in treating patients with acromegaly caused by nonpituitary tumors. Long-acting SSAs are given by intramuscular injection once a month.\n \nDigestive problems-such as loose stools, nausea, and gas-are a side effect in about half of people taking SSAs. However, the effects are usually temporary and rarely severe. About 10 to 20 percent of patients develop gallstones, but the gallstones do not usually cause symptoms. In rare cases, treatment can result in elevated blood glucose levels. More commonly, SSAs reduce the need for insulin and improve blood glucose control in some people with acromegaly who already have diabetes.\n \nThe second medication group is the GH receptor antagonists (GHRAs), which interfere with the action of GH. They normalize IGF-I levels in more than 90 percent of patients. They do not, however, lower GH levels. Given once a day through injection, GHRAs are usually well-tolerated by patients. The long-term effects of these drugs on tumor growth are still under study. Side effects can include headaches, fatigue, and abnormal liver function.\n \nDopamine agonists make up the third medication group. These drugs are not as effective as the other medications at lowering GH or IGF-I levels, and they normalize IGF-I levels in only a minority of patients. Dopamine agonists are sometimes effective in patients who have mild degrees of excess GH and have both acromegaly and hyperprolactinemiatoo much of the hormone prolactin. Dopamine agonists can be used in combination with SSAs. Side effects can include nausea, headache, and lightheadedness.\n \nAgonist: A drug that binds to a receptor of a cell and triggers a response by the cell, mimicking the action of a naturally occurring substance. Antagonist: A chemical that acts within the body to reduce the physiological activity of another chemical substance or hormone.\n \nRadiation Therapy\n \nRadiation therapy is usually reserved for people who have some tumor remaining after surgery and do not respond to medications. Because radiation leads to a slow lowering of GH and IGF-I levels, these patients often also receive medication to lower hormone levels. The full effect of this therapy may not occur for many years.\n \nThe two types of radiation delivery are conventional and stereotactic. Conventional radiation delivery targets the tumor with external beams but can damage surrounding tissue. The treatment delivers small doses of radiation multiple times over 4 to 6 weeks, giving normal tissue time to heal between treatments.\n \nStereotactic delivery allows precise targeting of a high-dose beam of radiation at the tumor from varying angles. The patient must wear a rigid head frame to keep the head still. The types of stereotactic radiation delivery currently available are proton beam, linear accelerator (LINAC), and gamma knife. With stereotactic delivery, the tumor must be at least 5 mm from the optic chiasm to prevent radiation damage. This treatment can sometimes be done in a single session, reducing the risk of damage to surrounding tissue.\n \nAll forms of radiation therapy cause a gradual decline in production of other pituitary hormones over time, resulting in the need for hormone replacement in most patients. Radiation also can impair a patients fertility. Vision loss and brain injury are rare complications. Rarely, secondary tumors can develop many years later in areas that were in the path of the radiation beam."} {"_id":"a0fbb77f-e324-487e-8b61-9095404748ff","text":"Currently, treatment options include surgical removal of the tumor, medical therapy, and radiation therapy of the pituitary.\n \nGoals of treatment are to\n \n- reduce excess hormone production to normal levels - relieve the pressure that the growing pituitary tumor may be exerting on the surrounding brain areas - preserve normal pituitary function or treat hormone deficiencies - improve the symptoms of acromegaly\n \nSurgery\n \nSurgery is the first option recommended for most people with acromegaly, as it is often a rapid and effective treatment.

It is a rare condition occurring in only one in 100,000 to 500,000 live births. Infants with NDM do not produce enough insulin, leading to an increase in blood glucose. NDM can be mistaken for the much more common type 1 diabetes, but type 1 diabetes usually occurs later than the first 6 months of life. In about half of those with NDM, the condition is lifelong and is called permanent neonatal diabetes mellitus (PNDM). In the rest of those with NDM, the condition is transient and disappears during infancy but can reappear later in life; this type of NDM is called transient neonatal diabetes mellitus (TNDM). Specific genes that can cause NDM have been identified. More information about each type of NDM is provided in the appendix.\n \nSymptoms of NDM include thirst, frequent urination, and dehydration. NDM can be diagnosed by finding elevated levels of glucose in blood or urine. In severe cases, the deficiency of insulin may cause the body to produce an excess of acid, resulting in a potentially life-threatening condition called ketoacidosis. Most fetuses with NDM do not grow well in the womb and newborns are much smaller than those of the same gestational age, a condition called intrauterine growth restriction.

A specially trained technician performs the procedure in a health care providers offi ce, outpatient center, or hospital, and a radiologista doctor who specializes in medical imaginginterprets the images. Anesthesia is not needed. If gallstones are present, they will be visible in the image. Ultrasound is the most accurate method to detect gallstones. - Computerized tomography (CT) scan. A CT scan is an x ray that produces pictures of the body. A CT scan may include the injection of a special dye, called contrast medium. CT scans use a combination of x rays and computer technology to create three-dimensional (3-D) images. CT scans require the person to lie on a table that slides into a tunnel-shaped device where the x rays are taken. An x-ray technician performs the procedure in an outpatient center or hospital, and a radiologist interprets the images. Anesthesia is not needed. CT scans can show gallstones or complications, such as infection and blockage of the gallbladder or bile ducts. However, CT scans can miss gallstones that are present. - Magnetic resonance imaging (MRI). MRI machines use radio waves and magnets to produce detailed pictures of the bodys internal organs and soft tissues without using x rays. A specially trained technician performs the procedure in an outpatient center or hospital, and a radiologist interprets the images. Anesthesia is not needed, though people with a fear of confi ned spaces may receive light sedation. An MRI may include the injection of contrast medium. With most MRI machines, the person lies on a table that slides into a tunnel-shaped device that may be open ended or closed at one end; some newer machines allow the person to lie in a more open space. MRIs can show gallstones in the ducts of the biliary system. - Cholescintigraphy. Cholescintigraphyalso called a hydroxyl iminodiacetic acid scan, HIDA scan, or hepatobiliary scanuses an unharmful radioactive material to produce pictures of the biliary system. In cholescintigraphy, the person lies on an exam table and a health care provider injects a small amount of unharmful radioactive material into a vein in the persons arm. The health care provider may also inject a substance that causes the gallbladder to contract. A special camera takes pictures of the radioactive material as it moves through the biliary system. A specially trained technician performs the procedure in an outpatient center or hospital, and a radiologist interprets the images. Anesthesia is not needed. Cholescintigraphy is used to diagnose abnormal contractions of the gallbladder or obstruction of the bile ducts. - Endoscopic retrograde cholangiopancreatography (ERCP). ERCP uses an x ray to look into the bile and pancreatic ducts. After lightly sedating the person, the health care provider inserts an endoscopea small, flexible tube with a light and a camera on the endthrough the mouth into the duodenum and bile ducts. The endoscope is connected to a computer and video monitor. The health care provider injects contrast medium through the tube into the bile ducts, which makes the ducts show up on the monitor. The health care provider performs the procedure in an outpatient center or hospital. ERCP helps the health care provider locate the affected bile duct and the gallstone. The stone is captured in a tiny basket attached to the endoscope and removed. This test is more invasive than other tests and is used selectively.\n \nHealth care providers also use blood tests to look for signs of infection or in flammation of the bile ducts, gallbladder, pancreas, or liver. A blood test involves drawing blood at a health care providers offi ce or commercial facility and sending the sample to a lab for analysis.\n \nGallstone symptoms may be similar to those of other conditions, such as appendicitis, ulcers, pancreatitis, and gastroesophageal refl ux disease.\n \nSometimes, silent gallstones are found when a person does not have any symptoms.

However, if a person has a gallbladder attack or other symptoms, a health care provider will usually recommend treatment. A person may be referred to a gastroenterologista doctor who specializes in digestive diseasesfor treatment. If a person has had one gallbladder attack, more episodes will likely follow.\n \nThe usual treatment for gallstones is surgery to remove the gallbladder. If a person cannot undergo surgery, nonsurgical treatments may be used to dissolve cholesterol gallstones. A health care provider may use ERCP to remove stones in people who cannot undergo surgery or to remove stones from the common bile duct in people who are about to have gallbladder removal surgery.\n \nSurgery\n \nSurgery to remove the gallbladder, called cholecystectomy, is one of the most common operations performed on adults in the United States.\n \nThe gallbladder is not an essential organ, which means a person can live normally without a gallbladder. Once the gallbladder is removed, bile flows out of the liver through the hepatic and common bile ducts and directly into the duodenum, instead of being stored in the gallbladder.\n \nSurgeons perform two types of cholecystectomy:\n \n- Laparoscopic cholecystectomy. In a laparoscopic cholecystectomy, the surgeon makes several tiny incisions in the abdomen and inserts a laparoscopea thin tube with a tiny video camera attached. The camera sends a magni fied image from inside the body to a video monitor, giving the surgeon a close-up view of organs and tissues. While watching the monitor, the surgeon uses instruments to carefully separate the gallbladder from the liver, bile ducts, and other structures. Then the surgeon removes the gallbladder through one of the small incisions. Patients usually receive general anesthesia. Most cholecystectomies are performed with laparoscopy. Many laparoscopic cholecystectomies are performed on an outpatient basis, meaning the person is able to go home the same day. Normal physical activity can usually be resumed in about a week.3 - Open cholecystectomy. An open cholecystectomy is performed when the gallbladder is severely infl amed, infected, or scarred from other operations. In most of these cases, open cholecystectomy is planned from the start. However, a surgeon may perform an open cholecystectomy when problems occur during a laparoscopic cholecystectomy. In these cases, the surgeon must switch to open cholecystectomy as a safety measure for the patient. To perform an open cholecystectomy, the surgeon creates an incision about 4 to 6 inches long in the abdomen to remove the gallbladder.4 Patients usually receive general anesthesia. Recovery from open cholecystectomy may require some people to stay in the hospital for up to a week. Normal physical activity can usually be resumed after about a month.3\n \nA small number of people have softer and more frequent stools after gallbladder removal because bile fl ows into the duodenum more often. Changes in bowel habits are usually temporary; however, they should be discussed with a health care provider.\n \nThough complications from gallbladder surgery are rare, the most common complication is injury to the bile ducts. An injured common bile duct can leak bile and cause a painful and possibly dangerous infection. One or more additional operations may be needed to repair the bile ducts. Bile duct injuries occur in less than 1 percent of cholecystectomies.5\n \nNonsurgical Treatments for Cholesterol Gallstones\n \nNonsurgical treatments are used only in special situations, such as when a person with cholesterol stones has a serious medical condition that prevents surgery. Gallstones often recur within 5 years after nonsurgical treatment.6\n \nTwo types of nonsurgical treatments can be used to dissolve cholesterol gallstones:\n \n- Oral dissolution therapy. Ursodiol (Actigall) and chenodiol (Chenix) are medications that contain bile acids that can dissolve gallstones. These medications are most effective in dissolving small cholesterol stones. Months or years of treatment may be needed to dissolve all stones. - Shock wave lithotripsy. A machine called a lithotripter is used to crush the gallstone. The lithotripter generates shock waves that pass through the persons body to break the gallstone into smaller pieces.

When the white blood cell count is higher than normal, a person may have inflammation or infection somewhere in the body.\n \nStool tests. A stool test is the analysis of a sample of stool. A health care provider will give the patient a container for catching and storing the stool. The patient returns the sample to the health care provider or a commercial facility that will send the sample to a lab for analysis. Health care providers commonly order stool tests to rule out other causes of GI diseases, such as different types of infectionsincluding bacteria or parasitesor bleeding, and help determine the cause of symptoms.\n \nImaging Tests of the Intestines\n \nImaging tests of the intestines may include the following:\n \n- computerized tomography (CT) scan - magnetic resonance imaging (MRI) - upper GI series\n \nSpecially trained technicians perform these tests at an outpatient center or a hospital, and a radiologista doctor who specializes in medical imaginginterprets the images. A patient does not need anesthesia. Health care providers use imaging tests to show physical abnormalities and to diagnose certain bowel diseases, in some cases.\n \nCT scan. CT scans use a combination of x rays and computer technology to create images. For a CT scan, a health care provider may give the patient a solution to drink and an injection of a special dye, called contrast medium. CT scans require the patient to lie on a table that slides into a tunnel-shaped device where the technician takes the x rays.\n \nMRI. MRI is a test that takes pictures of the bodys internal organs and soft tissues without using x rays. Although a patient does not need anesthesia for an MRI, some patients with a fear of confined spaces may receive light sedation, taken by mouth. An MRI may include a solution to drink and injection of contrast medium. With most MRI machines, the patient will lie on a table that slides into a tunnel-shaped device that may be open ended or closed at one end. Some machines allow the patient to lie in a more open space. During an MRI, the patient, although usually awake, must remain perfectly still while the technician takes the images, which usually takes only a few minutes. The technician will take a sequence of images to create a detailed picture of the intestines. During sequencing, the patient will hear loud mechanical knocking and humming noises.\n \nUpper GI series. This test is an x-ray exam that provides a look at the shape of the upper GI tract. A patient should not eat or drink before the procedure, as directed by the health care provider. Patients should ask their health care provider about how to prepare for an upper GI series. During the procedure, the patient will stand or sit in front of an x-ray machine and drink barium, a chalky liquid. Barium coats the upper GI tract so the radiologist and gastroenterologist can see the organs shapes more clearly on x rays. A patient may experience bloating and nausea for a short time after the test. For several days afterward, barium liquid in the GI tract causes white or light-colored stools. A health care provider will give the patient specific instructions about eating and drinking after the test. More information is provided in the NIDDK health topic, Upper GI Series.\n \nEndoscopy of the Intestines\n \nEndoscopy of the intestines may include\n \n- colonoscopy with biopsy - flexible sigmoidoscopy with biopsy - upper GI endoscopy with biopsy\n \nA gastroenterologist performs these tests at a hospital or an outpatient center.\n \nColonoscopy with biopsy. Colonoscopy is a test that uses a long, flexible, narrow tube with a light and tiny camera on one end, called a colonoscope or scope, to look inside the rectum and entire colon. In most cases, light anesthesia and pain medication help patients relax for the test. The medical staff will monitor a patients vital signs and try to make him or her as comfortable as possible. A nurse or technician places an intravenous (IV) needle in a vein in the arm or hand to give anesthesia.\n \nFor the test, the patient will lie on a table while the gastroenterologist inserts a colonoscope into the anus and slowly guides it through the rectum and into the colon. The scope inflates the large intestine with air to give the gastroenterologist a better view. The camera sends a video image of the intestinal lining to a computer screen, allowing the gastroenterologist to carefully examine the tissues lining the colon and rectum. The gastroenterologist may move the patient several times and adjust the scope for better viewing. Once the scope has reached the opening to the small intestine, the gastroenterologist slowly withdraws it and examines the lining of the colon and rectum again. A colonoscopy can show irritated and swollen tissue, ulcers, and abnormal growths such as polypsextra pieces of tissue that grow on the lining of the intestine. If the lining of the rectum and colon appears normal, the gastroenterologist may suspect microscopic colitis and will biopsy multiple areas of the colon.\n \nA health care provider will provide written bowel prep instructions to follow at home before the test. The health care provider will also explain what the patient can expect after the test and give discharge instructions.\n \nFlexible sigmoidoscopy with biopsy. Flexible sigmoidoscopy is a test that uses a flexible, narrow tube with a light and tiny camera on one end, called a sigmoidoscope or scope, to look inside the rectum and the sigmoid colon. A patient does not usually need anesthesia.\n \nFor the test, the patient will lie on a table while the gastroenterologist inserts the sigmoidoscope into the anus and slowly guides it through the rectum and into the sigmoid colon. The scope inflates the large intestine with air to give the gastroenterologist a better view. The camera sends a video image of the intestinal lining to a computer screen, allowing the gastroenterologist to carefully examine the tissues lining the sigmoid colon and rectum. The gastroenterologist may ask the patient to move several times and adjust the scope for better viewing. Once the scope reaches the end of the sigmoid colon, the gastroenterologist slowly withdraws it while carefully examining the lining of the sigmoid colon and rectum again.\n \nThe gastroenterologist will look for signs of bowel diseases and conditions such as irritated and swollen tissue, ulcers, and polyps. If the lining of the rectum and colon appears normal, the gastroenterologist may suspect microscopic colitis and will biopsy multiple areas of the colon.\n \nA health care provider will provide written bowel prep instructions to follow at home before the test. The health care provider will also explain what the patient can expect after the test and give discharge instructions.\n \nUpper GI endoscopy with biopsy. Upper GI endoscopy is a test that uses a flexible, narrow tube with a light and tiny camera on one end, called an endoscope or a scope, to look inside the upper GI tract. The gastroenterologist carefully feeds the endoscope down the esophagus and into the stomach and first part of the small intestine, called the duodenum. A small camera mounted on the endoscope transmits a video image to a monitor, allowing close examination of the intestinal lining. A health care provider may give a patient a liquid anesthetic to gargle or may spray anesthetic on the back of the patients throat. A health care provider will place an IV needle in a vein in the arm or hand to administer sedation. Sedatives help patients stay relaxed and comfortable. This test can show blockages or other conditions in the upper small intestine. A gastroenterologist may biopsy the lining of the small intestine during an upper GI endoscopy."} {"_id":"6127ae73-0fce-44e8-8163-914c2bb5ae0a","text":"Treatment depends on the severity of symptoms.

Loose stools fill the rectum quickly and are more difficult to hold than solid stools. Diarrhea increases the chance of not reaching a bathroom in time.\n \nConstipation\n \nConstipation can lead to large, hard stools that stretch the rectum and cause the internal sphincter muscles to relax by reflex. Watery stool builds up behind the hard stool and may leak out around the hard stool, leading to fecal incontinence.\n \nThe type of constipation that is most likely to lead to fecal incontinence occurs when people are unable to relax their external sphincter and pelvic floor muscles when straining to have a bowel movement, often mistakenly squeezing these muscles instead of relaxing them. This squeezing makes it difficult to pass stool and may lead to a large amount of stool in the rectum. This type of constipation, called dyssynergic defecation or disordered defecation, is a result of faulty learning. For example, children or adults who have pain when having a bowel movement may unconsciously learn to squeeze their muscles to delay the bowel movement and avoid pain.\n \nMuscle Damage or Weakness\n \nInjury to one or both of the sphincter muscles can cause fecal incontinence. If these muscles, called the external and internal anal sphincter muscles, are damaged or weakened, they may not be strong enough to keep the anus closed and prevent stool from leaking.\n \nTrauma, childbirth injuries, cancer surgery, and hemorrhoid surgery are possible causes of injury to the sphincters. Hemorrhoids are swollen blood vessels in and around the anus and lower rectum.\n \nNerve Damage\n \nThe anal sphincter muscles wont open and close properly if the nerves that control them are damaged. Likewise, if the nerves that sense stool in the rectum are damaged, a person may not feel the urge to go to the bathroom. Both types of nerve damage can lead to fecal incontinence. Possible sources of nerve damage are childbirth; a long-term habit of straining to pass stool; spinal cord injury; and diseases, such as diabetes and multiple sclerosis, that affect the nerves that go to the sphincter muscles and rectum. Brain injuries from stroke, head trauma, or certain diseases can also cause fecal incontinence.\n \nLoss of Stretch in the Rectum\n \nNormally, the rectum stretches to hold stool until a person has a bowel movement. Rectal surgery, radiation treatment, and inflammatory bowel diseaseschronic disorders that cause irritation and sores on the lining of the digestive systemcan cause the rectal walls to become stiff. The rectum then cant stretch as much to hold stool, increasing the risk of fecal incontinence.\n \nChildbirth by Vaginal Delivery\n \nChildbirth sometimes causes injuries to muscles and nerves in the pelvic floor. The risk is greater if forceps are used to help deliver the baby or if an episiotomya cut in the vaginal area to prevent the babys head from tearing the vagina during birthis performed. Fecal incontinence related to childbirth can appear soon after delivery or many years later.\n \nHemorrhoids and Rectal Prolapse\n \nExternal hemorrhoids, which develop under the skin around the anus, can prevent the anal sphincter muscles from closing completely. Rectal prolapse, a condition that causes the rectum to drop down through the anus, can also prevent the anal sphincter muscles from closing well enough to prevent leakage. Small amounts of mucus or liquid stool can then leak through the anus.\n \nRectocele\n \nRectocele is a condition that causes the rectum to protrude through the vagina. Rectocele can happen when the thin layer of muscles separating the rectum from the vagina becomes weak. For women with rectocele, straining to have a bowel movement may be less effective because rectocele reduces the amount of downward force through the anus. The result may be retention of stool in the rectum. More research is needed to be sure rectocele increases the risk of fecal incontinence.\n \nInactivity\n \nPeople who are inactive, especially those who spend many hours a day sitting or lying down, have an increased risk of retaining a large amount of stool in the rectum. Liquid stool can then leak around the more solid stool. Frail, older adults are most likely to develop constipation-related fecal incontinence for this reason."} {"_id":"e542784e-b4e8-438b-847e-15d8dc9ca834","text":"Health care providers diagnose fecal incontinence based on a persons medical history, physical exam, and medical test results. In addition to a general medical history, the health care provider may ask the following questions:\n \n- When did fecal incontinence start? - How often does fecal incontinence occur? - How much stool leaks? Does the stool just streak the underwear? Does just a little bit of solid or liquid stool leak out or does complete loss of bowel control occur? - Does fecal incontinence involve a strong urge to have a bowel movement or does it happen without warning? - For people with hemorrhoids, do hemorrhoids bulge through the anus? Do the hemorrhoids pull back in by themselves, or do they have to be pushed in with a finger? - How does fecal incontinence affect daily life? - Is fecal incontinence worse after eating? Do certain foods seem to make fecal incontinence worse? - Can passing gas be controlled?\n \nPeople may want to keep a stool diary for several weeks before their appointment so they can answer these questions. A stool diary is a chart for recording daily bowel movement details. A sample stool diary is available on the Bowel Control Awareness Campaign website at www.bowelcontrol.nih.gov.\n \nThe person may be referred to a doctor who specializes in problems of the digestive system, such as a gastroenterologist, proctologist, or colorectal surgeon, or a doctor who specializes in problems of the urinary and reproductive systems, such as a urologist or urogynecologist. The specialist will perform a physical exam and may suggest one or more of the following tests:\n \n- anal manometry - anal ultrasound - magnetic resonance imaging (MRI) - defecography - flexible sigmoidoscopy or colonoscopy - anal electromyography (EMG)\n \nAnal manometry. Anal manometry uses pressure sensors and a balloon that can be inflated in the rectum to check the sensitivity and function of the rectum. Anal manometry also checks the tightness of the anal sphincter muscles around the anus. To prepare for this test, the person should use an enema and not eat anything 2 hours before the test. An enema involves flushing water or a laxative into the anus using a special squirt bottle. A laxative is medication that loosens stool and increases bowel movements. For this test, a thin tube with a balloon on its tip and pressure sensors below the balloon is inserted into the anus until the balloon is in the rectum and pressure sensors are located in the anal canal. The tube is slowly pulled back through the sphincter muscle to measure muscle tone and contractions. No anesthesia is needed for this test, which takes about 30 minutes.\n \nAnal ultrasound. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. An anal ultrasound is specific to the anus and rectum. The procedure is performed in a health care providers office, outpatient center, or hospital by a specially trained technician, and the images are interpreted by a radiologista doctor who specializes in medical imaging. Anesthesia is not needed. The images can show the structure of the anal sphincter muscles.\n \nMRI. MRI machines use radio waves and magnets to produce detailed pictures of the bodys internal organs and soft tissues without using x rays. The procedure is performed in an outpatient center or hospital by a specially trained technician, and the images are interpreted by a radiologist. Anesthesia is not needed, though people with a fear of confined spaces may be given medication to help them relax. An MRI may include the injection of special dye, called contrast medium. With most MRI machines, the person lies on a table that slides into a tunnel-shaped device that may be open ended or closed at one end; some newer machines are designed to allow the person to lie in a more open space. MRIs can show problems with the anal sphincter muscles. MRI is an alternative to anal ultrasound that may provide more detailed information, especially about the external anal sphincter.\n \nDefecography. This x ray of the area around the anus and rectum shows how well the person can hold and evacuate stool. The test also identifies structural changes in the rectum and anus such as rectocele and rectal prolapse. To prepare for the test, the person uses two enemas and does not eat anything 2 hours prior to the test. During the test, the health care provider fills the rectum with a soft paste that shows up on x rays and is the same consistency as stool. The person sits on a toilet inside an x-ray machine. The person is first asked to pull in and squeeze the sphincter muscles to prevent leakage and then to strain as if having a bowel movement. The radiologist studies the x rays to identify problems with the rectum, anus, and pelvic floor muscles.\n \nFlexible sigmoidoscopy or colonoscopy. These tests are used to help diagnose problems causing fecal incontinence. The tests are similar, but colonoscopy is used to view the rectum and entire colon, while flexible sigmoidoscopy is used to view just the rectum and lower colon. These tests are performed at a hospital or outpatient center by a gastroenterologist. For both tests, a health care provider will provide written bowel prep instructions to follow at home. The person may be asked to follow a clear liquid diet for 1 to 3 days before either test. A laxative may be required the night before the test. One or more enemas may be required the night before and about 2 hours before the test.\n \nIn most cases, people will be given light anesthesia, and possibly pain medication, to help them relax during flexible sigmoidoscopy. Anesthesia is used for colonoscopy. For either test, the person will lie on a table while the gastroenterologist inserts a flexible tube into the anus. A small camera on the tube sends a video image of the intestinal lining to a computer screen. The test can show problems in the lower GI tract that may be causing the bowel control problem. The gastroenterologist may also perform a biopsy, a procedure that involves taking a piece of tissue from the bowel lining for examination with a microscope.\n \nThe person will not feel the biopsy. A pathologista doctor who specializes in diagnosing diseasesexamines the tissue in a lab to confirm the diagnosis.\n \nCramping or bloating may occur during the first hour after these tests. Driving is not permitted for 24 hours after flexible sigmoidoscopy or colonoscopy to allow the anesthesia time to wear off. Before the appointment, a person should make plans for a ride home. Full recovery is expected by the next day and the person is able to go back to a normal diet.\n \nAnal EMG. Anal EMG checks the health of the pelvic floor muscles and the nerves that control the muscles. The health care provider inserts a very thin needle electrode through the skin into the muscle. The electrode on the needle picks up the electrical activity given off by the muscles and shows it as images on a monitor or sounds through a speaker. An alternative type of anal EMG uses stainless steel plates attached to the sides of a plastic plug instead of a needle. The plug is inserted into the anal canal to measure the electrical activity of the external anal sphincter and other pelvic floor muscles. The average amount of electrical activity when the person relaxes quietly, squeezes to prevent a bowel movement, and strains to have a bowel movement shows whether there is damage to the nerves that control the external sphincter and pelvic floor muscles."} {"_id":"feebbce9-d37f-459d-a3b8-666fe3b9fccf","text":"Treatment for fecal incontinence may include one or more of the following:\n \n- eating, diet, and nutrition - medications - bowel training - pelvic floor exercises and biofeedback - surgery - electrical stimulation"} {"_id":"db5e9853-58fd-4c1a-8a83-ad3c916fb690","text":"Dietary changes that may improve fecal incontinence include\n \n- Eating the right amount of fiber. Fiber can help with diarrhea and constipation. Fiber is found in fruits, vegetables, whole grains, and beans. Fiber supplements sold in a pharmacy or in a health food store are another common source of fiber to treat fecal incontinence. The Academy of Nutrition and Dietetics recommends consuming 20 to 35 grams of fiber a day for adults and age plus five grams for children. A 7-year-old child, for example, should get 7 plus five, or 12, grams of fiber a day. American adults consume only 15 grams a day on average.2 Fiber should be added to the diet slowly to avoid bloating. - Getting plenty to drink. Drinking eight 8-ounce glasses of liquid a day may help prevent constipation. Water is a good choice. Drinks with caffeine, alcohol, milk, or carbonation should be avoided if they trigger diarrhea.\n \nKeeping a Food Diary A food diary can help identify foods that cause diarrhea and increase the risk of fecal incontinence. A food diary should list foods eaten, portion size, and when fecal incontinence occurs. After a few days, the diary may show a link between certain foods and fecal incontinence. Eating less of foods linked to fecal incontinence may improve symptoms. A food diary can also be helpful to a health care provider treating a person with fecal incontinence. Common foods and drinks linked to fecal incontinence include - dairy products such as milk, cheese, and ice cream - drinks and foods containing caffeine - cured or smoked meat such as sausage, ham, and turkey - spicy foods - alcoholic beverages - fruits such as apples, peaches, and pears - fatty and greasy foods - sweeteners in diet drinks and sugarless gum and candy, including sorbitol, xylitol, mannitol, and fructose\n \n\n \nExamples of Foods That Have Fiber Beans, cereals, and breads Fiber cup of beans (navy, pinto, kidney, etc.), cooked 6.29.6 grams cup of shredded wheat, ready-to-eat cereal 2.73.8 grams cup of 100% bran, ready-to-eat cereal 9.1 grams 1 small oat bran muffin 3.0 grams 1 whole-wheat English muffin 4.4 grams Fruits 1 small apple, with skin 3.6 grams 1 medium pear, with skin 5.5 grams cup of raspberries 4.0 grams cup of stewed prunes 3.8 grams Vegetables cup of winter squash, cooked 2.9 grams 1 medium sweet potato, baked in skin 3.8 grams cup of green peas, cooked 3.54.4 grams 1 small potato, baked, with skin 3.0 grams cup of mixed vegetables, cooked 4.0 grams cup of broccoli, cooked 2.62.8 grams cup of greens (spinach, collards, turnip greens), cooked 2.53.5 grams\n \n\n \nMedications\n \nIf diarrhea is causing fecal incontinence, medication may help. Health care providers sometimes recommend using bulk laxatives, such as Citrucel and Metamucil, to develop more solid stools that are easier to control. Antidiarrheal medications such as loperamide or diphenoxylate may be recommended to slow down the bowels and help control the problem.\n \nBowel Training\n \nDeveloping a regular bowel movement pattern can improve fecal incontinence, especially fecal incontinence due to constipation. Bowel training involves trying to have bowel movements at specific times of the day, such as after every meal. Over time, the body becomes used to a regular bowel movement pattern, thus reducing constipation and related fecal incontinence. Persistence is key to successful bowel training. Achieving a regular bowel control pattern can take weeks to months.\n \nPelvic Floor Exercises and Biofeedback\n \nExercises that strengthen the pelvic floor muscles may improve bowel control. Pelvic floor exercises involve squeezing and relaxing pelvic floor muscles 50 to 100 times a day. A health care provider can help with proper technique. Biofeedback therapy may also help a person perform the exercises properly. This therapy also improves a persons awareness of sensations in the rectum, teaching how to coordinate squeezing of the external sphincter muscle with the sensation of rectal filling. Biofeedback training uses special sensors to measure bodily functions. Sensors include pressure or EMG sensors in the anus, pressure sensors in the rectum, and a balloon in the rectum to produce graded sensations of rectal fullness. The measurements are displayed on a video screen as sounds or line graphs. The health care provider uses the information to help the person modify or change abnormal function. The person practices the exercises at home. Success with pelvic floor exercises depends on the cause of fecal incontinence, its severity, and the persons motivation and ability to follow the health care providers recommendations.\n \nSurgery\n \nSurgery may be an option for fecal incontinence that fails to improve with other treatments or for fecal incontinence caused by pelvic floor or anal sphincter muscle injuries.\n \n- Sphincteroplasty, the most common fecal incontinence surgery, reconnects the separated ends of a sphincter muscle torn by childbirth or another injury. Sphincteroplasty is performed at a hospital by a colorectal, gynecological, or general surgeon. - Artificial anal sphincter involves placing an inflatable cuff around the anus and implanting a small pump beneath the skin that the person activates to inflate or deflate the cuff. This surgery is much less common and is performed at a hospital by a specially trained colorectal surgeon. - Nonabsorbable bulking agents can be injected into the wall of the anus to bulk up the tissue around the anus. The bulkier tissues make the opening of the anus narrower so the sphincters are able to close better. The procedure is performed in a health care providers office; anesthesia is not needed. The person can return to normal physical activities 1 week after the procedure. - Bowel diversion is an operation that reroutes the normal movement of stool out of the body when part of the bowel is removed. The operation diverts the lower part of the small intestine or colon to an opening in the wall of the abdomenthe area between the chest and hips. An external pouch is attached to the opening to collect stool. The procedure is performed by a surgeon in a hospital and anesthesia is used. More information about these procedures can be found in the Bowel Diversion fact sheet.\n \nElectrical Stimulation\n \nElectrical stimulation, also called sacral nerve stimulation or neuromodulation, involves placing electrodes in the sacral nerves to the anus and rectum and continuously stimulating the nerves with electrical pulses. The sacral nerves connect to the part of the spine in the hip area. A battery-operated stimulator is placed beneath the skin. Based on the persons response, the health care provider can adjust the amount of stimulation so it works best for that person. The person can turn the stimulator on or off at any time. The procedure is performed in an outpatient center using local anesthesia."} {"_id":"e81e57c0-eff0-49ff-8675-a9dd4e8657b4","text":"Fecal incontinence can cause embarrassment, fear, and loneliness. Taking steps to cope is important. The following tips can help:\n \n- carrying a bag with cleanup supplies and a change of clothes when leaving the house. - finding public restrooms before one is needed. - using the toilet before leaving home. - wearing disposable underwear or absorbent pads inserted in the underwear. - using fecal deodorantspills that reduce the smell of stool and gas. Although fecal deodorants are available over the counter, a health care provider can help people find them.\n \nEating tends to trigger contractions of the large intestine that push stool toward the rectum and also cause the rectum to contract for 30 to 60 minutes. Both these events increase the likelihood that a person will pass gas and have a bowel movement soon after eating. This activity may increase if the person is anxious. People with fecal incontinence may want to avoid eating in restaurants or at social gatherings, or they may want to take antidiarrheal medications before eating in these situations.\n \nAnal Discomfort The skin around the anus is delicate and sensitive. Constipation and diarrhea or contact between skin and stool can cause pain or itching. The following steps can help relieve anal discomfort: - Washing the anal area after a bowel movement. Washing with water, but not soap, can help prevent discomfort. Soap can dry out the skin, making discomfort worse. Ideally, the anal area should be washed in the shower with lukewarm water or in a sitz batha special plastic tub that allows a person to sit in a few inches of warm water. No-rinse skin cleansers, such as Cavilon, are a good alternative. Wiping with toilet paper further irritates the skin and should be avoided. Premoistened, alcohol-free towelettes are a better choice. - Keeping the anal area dry. The anal area should be allowed to air dry after washing. If time doesnt permit air drying, the anal area can be gently patted dry with a lint-free cloth. - Creating a moisture barrier. A moisture barrier cream that contains ingredients such as dimethiconea type of siliconecan help form a barrier between skin and stool. The anal area should be cleaned before applying barrier cream. However, people should talk with their health care provider before using anal creams and ointments because some can irritate the anus. - Using nonmedicated powders. Nonmedicated talcum powder or cornstarch can also relieve anal discomfort. As with moisture barrier creams, the anal area should be clean and dry before use. - Using wicking pads or disposable underwear. Pads and disposable underwear with a wicking layer can pull moisture away from the skin. - Wearing breathable clothes and underwear. Clothes and underwear should allow air to flow and keep skin dry. Tight clothes or plastic or rubber underwear that blocks air can worsen skin problems. - Changing soiled underwear as soon as possible."} {"_id":"bac2a26c-8ea2-426f-8e31-cb245ad61307","text":"- Fecal incontinence, also called a bowel control problem, is the accidental passing of solid or liquid stool or mucus from the rectum.

This type of dialysis uses a machine to remove harmful wastes and extra fluid, as your kidneys did when they were healthy. Hemodialysis helps control blood pressure and balance important minerals, such as potassium, sodium, calcium, and bicarbonate, in your blood. Hemodialysis is not a cure for kidney failure; however, it can help you feel better and live longer.\n \nHow Hemodialysis Works\n \nBefore you can begin dialysis, a surgeon will create a vascular access, usually in your arm. A vascular access lets high volumes of blood flow continuously during hemodialysis treatments to filter the largest possible amounts of blood per treatment.\n \nHemodialysis uses a machine to move your blood through a filter, called a dialyzer, outside your body. A pump on the hemodialysis machine draws your blood through a needle into a tube, a few ounces at a time. Your blood then travels through the tube, which takes it to the dialyzer. Inside the dialyzer, your blood flows through thin fibers that filter out wastes and extra fluid. After the dialyzer filters your blood, another tube carries your blood back to your body. You can do hemodialysis at a dialysis center or in your home.\n \nHemodialysis can replace part of your kidney function. You will also need dietary changes, medicines, and limits on water and other liquids you drink and get from food. Your dietary changes, the number of medicines you need, and limits on liquid will depend on where you receive your treatmentsat a dialysis center or at homeand how often you receive treatmentsthree or more times a week.\n \nPros and Cons of Hemodialysis\n \nThe pros and cons of hemodialysis differ for each person. What may be bad for one person may be good for another. Following is a list of the general pros and cons of dialysis center and home hemodialysis.\n \nDialysis Center Hemodialysis\n \nPros\n \n- Dialysis centers are widely available. - Trained health care providers are with you at all times and help administer the treatment. - You can get to know other people with kidney failure who also need hemodialysis. - You dont have to have a trained partner or keep equipment in your home.\n \nCons\n \n- The center arranges everyones treatments and allows few exceptions to the schedule. - You need to travel to the center for treatment. - This treatment has the strictest diet and limits on liquids because the longer time between treatments means wastes and extra fluid can build up in your body. - You may have more frequent ups and downs in how you feel from day to day because of the longer time between sessions. - Feeling better after a treatment may take a few hours.\n \nHome Hemodialysis\n \nPros\n \n- You can do the treatment at the times you choose; however, you should follow your doctors orders about how many times a week you need treatment. - You dont have to travel to a dialysis center. - You gain a sense of control over your treatment. - You will have fewer ups and downs in how you feel from day to day because of more frequent sessions. - You can do your treatments at times that will let you work outside the home. - You will have a more manageable diet and fewer limits on liquids because the shorter time between sessions prevents the buildup of wastes and extra fluid. - You can take along a hemodialysis machine when traveling. - You can spend more time with your loved ones because you dont have to go to the dialysis center three times a week.\n \nCons\n \n- Not all dialysis centers offer home hemodialysis training and support. - You and a family member or friend will have to set aside a week or more at the beginning for training. - Helping with treatments may be stressful for your family or friend. - You need space for storing the hemodialysis machine and supplies at home. - You will need to learn to put dialysis needles into your vascular access. - Medicare and private insurance companies may limit the number of treatments they will pay for when you use home hemodialysis. Few people can afford the costs for additional treatments.\n \nQuestions to Ask My Doctor\n \nYou may want to ask your doctor these questions:\n \n- Is hemodialysis the best treatment choice for me? Why? - If Im treated at a dialysis center, can I go to the center of my choice? - What should I look for in a dialysis center? - Will my kidney doctor see me at the dialysis center? - What does hemodialysis feel like? - How will hemodialysis affect my ____ [blood pressure, diabetes, other conditions]? - Is home hemodialysis available in my area? What type of training will I need? Who will train my partner and me? - Will I be able to keep working? Can I have treatments at night? Will I be able to care for my children? - How much should I exercise? - Whom do I contact if I have problems? - Who will be on my health care team? How can the members of my health care team help me? - If I do home hemodialysis, will my insurance pay for more than three sessions a week? - With whom can I talk about finances, sex, or family concerns? - How\/where can I talk with other people who have faced this decision?\n \nMore information about Hemodialysis and Home Hemodialysis is provided in the NIDDK health topics, Treatment Methods for Kidney Failure: Hemodialysis and Home Hemodialysis.

This type of dialysis uses the lining of your bellythe space in your body that holds your stomach, bowels, and liverto filter your blood. This lining, called the peritoneum, acts to do the work of your kidneys.\n \nHow Peritoneal Dialysis Works\n \nA doctor will place a soft tube, called a catheter, in your belly a few weeks before you start treatment. The catheter stays in your belly permanently. When you start peritoneal dialysis, you will empty a kind of salty water, called dialysis solution, from a plastic bag through the catheter into your belly. When the bag is empty, you can disconnect your catheter from the bag so you can move around and do your normal activities. While the dialysis solution is inside your belly, it soaks up wastes and extra fluid from your body. After a few hours, you drain the used dialysis solution through another tube into a drain bag. You can throw away the used dialysis solution, now filled with wastes and extra fluid, in a toilet or tub. Then you start over with a fresh bag of dialysis solution. The process of emptying the used dialysis solution and refilling your belly with fresh solution is called an exchange. The process goes on continuously, so you always have dialysis solution in your belly soaking up wastes and extra fluid from your body.\n \nTypes of Peritoneal Dialysis\n \nTwo types of peritoneal dialysis are available. After you have learned about the types of peritoneal dialysis, you can choose the type that best fits your life. If one schedule or type of peritoneal dialysis does not suit you, talk with your doctor about trying the other type.\n \n- Continuous ambulatory peritoneal dialysis does not require a machine and you can do it in any clean, well-lit place. The time period that the dialysis solution is in your belly is the dwell time. With continuous ambulatory peritoneal dialysis, the dialysis solution stays in your belly for a dwell time of 4 to 6 hours, or more. The process of draining the used dialysis solution and replacing it with fresh solution takes about 30 to 40 minutes. Most people change the dialysis solution at least four times a day and sleep with solution in their belly at night. With continuous ambulatory peritoneal dialysis, you do not have to wake up and perform dialysis tasks during the night. - Continuous cycler-assisted peritoneal dialysis uses a machine called a cycler to fill and empty your belly three to five times during the night while you sleep. In the morning, you begin one exchange with a dwell time that lasts the entire day. You may do an additional exchange in the middle of the afternoon without the cycler to increase the amount of waste removed and to reduce the amount of fluid left behind in your body.\n \nYou may need a combination of continuous ambulatory peritoneal dialysis and continuous cycler-assisted peritoneal dialysis if you weigh more than 175 pounds or if your peritoneum filters wastes slowly. For example, some people use a cycler at night and perform one exchange during the day. Others do four exchanges during the day and use a minicycler to perform one or more exchanges during the night. Youll work with your health care team to find the best schedule for you.\n \nPros and Cons of Peritoneal Dialysis\n \nEach type of peritoneal dialysis has pros and cons.\n \nContinuous Ambulatory Peritoneal Dialysis\n \nPros\n \n- You can do continuous ambulatory peritoneal dialysis alone. - You can do continuous ambulatory peritoneal dialysis at the times you choose, as long as you perform the required number of exchanges each day. - You can do continuous ambulatory peritoneal dialysis in many locations. - You can travel as long as you bring dialysis bags with you or have them delivered to your destination. - You dont need a machine for continuous ambulatory peritoneal dialysis. - You gain a sense of control over your treatment.\n \nCons\n \n- Continuous ambulatory peritoneal dialysis can disrupt your daily schedule. - Continuous ambulatory peritoneal dialysis is a continuous treatment, and you should do all exchanges 7 days a week. - Boxes of dialysis solution will take up space in your home.\n \nContinuous Cycler-assisted Peritoneal Dialysis\n \nPros\n \n- You can do exchanges at night, while you sleep. - You may not have to perform exchanges during the day.\n \nCons\n \n- You need a machine. - Your connection to the cycler limits your movement at night.\n \nQuestions to Ask My Doctor\n \n- Is peritoneal dialysis the best treatment choice for me? Why? If yes, which type is best? - What type of training do I need, and how long will it take? - What does peritoneal dialysis feel like? - How will peritoneal dialysis affect my ____ [blood pressure, diabetes, other conditions]? - Will I be able to keep working? Will I be able to care for my children? - How much should I exercise? - Where do I store supplies? - How often do I see my doctor? - Who will be on my health care team?

A kidney from someone who has just died is a deceased donor kidney. A kidney from a living person is a living donor kidney. A functioning kidney transplant does a better job of filtering wastes and keeping you healthy than dialysis.\n \nHow Kidney Transplantation Works\n \nSurgeonsdoctors who specialize in surgeryplace most transplanted kidneys in the lower front part of your abdomen. The kidney is connected to an artery, which brings unfiltered blood into the kidney, and a vein, which takes filtered blood out of the kidney. The surgeon also transplants the ureter from the donor to let urine from the new kidney flow to your bladder. Unless your damaged kidneys cause problems such as infection, they can remain in their normal position. The transplanted kidney takes over the job of filtering your blood. Your body normally attacks anything it sees as foreign, so to keep your body from attacking the kidney you need to take medicines called immunosuppressants for as long as the transplanted kidney functions.\n \nPros and Cons of Kidney Transplantation\n \nFollowing is a list of the pros and cons of kidney transplantation.\n \nKidney Transplantation\n \nPros\n \n- A transplanted kidney works like a healthy kidney. - If you have a living donor, you can choose the time of your operation. - You may feel healthier and have an improved quality of life. - You have fewer dietary restrictions. - You wont need dialysis. - People who receive a donated kidney have a greater chance of living a longer life than those who stay on dialysis.\n \nCons\n \n- Transplantation requires surgery. - You will go through extensive medical testing at the transplant clinic. - You may need to wait years for a deceased donor kidney. - Your body may reject the new kidney, so one transplant may not last a lifetime. - Youll need to take immunosuppressants, which may cause other health problems, for as long as the transplanted kidney functions.\n \nQuestions to Ask My Doctor\n \nYou may want to ask your doctor these questions:\n \n- Is transplantation the best treatment choice for me? Why? - What are my chances of having a successful transplant? - How do I find out whether a family member or friend can donate? - What are the risks to a family member or friend who donates? - If a family member or friend does not donate, who will place me on a waiting list for a kidney? How long will I have to wait? - How will I know if my donor kidney is working? - How long does a transplanted kidney function? - What side effects do immunosuppressants cause? - Who will be on my transplant team?

For many people, dialysis not only extends life, it also improves the quality of life. For others who have serious conditions in addition to kidney failure, dialysis may seem like a burden that only prolongs suffering. If you have serious conditions in addition to kidney failure, dialysis may not prolong your life or improve the quality of your life.\n \nYou have the right to say no to or stop dialysis. You may want to speak with your doctor, spouse, family, counselor, or renal social worker, who helps people with kidney disease, to help you make this decision.\n \nIf you stop dialysis treatments or say you do not want to begin them, you may live for a few weeks or for several months, depending on your health and your remaining kidney function. You may choose to receive care from a hospicea facility or home program designed to meet the physical and emotional needs of the terminally illduring this time. Hospice care focuses on relief of pain and other symptoms. Whether or not you choose to use a hospice, your doctor can give you medicines to make you more comfortable. Your doctor can also give you medicines to treat the problems of kidney failure, such as anemia or weak bones. You may restart dialysis treatment if you change your mind.\n \nAdvance Directives\n \nAn advance directive is a statement or document in which you give instructions either to withhold certain treatments, such as dialysis, or to provide them, depending on your wishes and the specific circumstances. Even if you are happy with your quality of life on dialysis, you should think about circumstances that might make you want to stop dialysis treatments. At some point in a medical crisis, you might lose the ability to tell your health care team and loved ones what you want. Advance directives may include\n \n- a living will - a durable power of attorney for health care decisions - a do not resuscitate (DNR) ordera legal form that tells your health care team you do not want cardiopulmonary resuscitation (CPR) or other life-sustaining treatment if your heart were to stop or if you were to stop breathing.\n \nA living will is a document that details the conditions under which you would want to refuse treatment. You may state that you want your health care team to use all available means to sustain your life, or you may direct that you be withdrawn from dialysis if you fall into a coma from which you most likely wont wake up. In addition to dialysis, you may choose or refuse the following life-sustaining treatments:\n \n- CPR - feedings through a tube in your stomach - mechanical or artificial means to help you breathe - medicines to treat infections - surgery - receiving blood\n \nRefusing to have CPR is the same as a DNR order. If you choose to have a DNR order, your doctor will place the order in your medical chart.\n \nA durable power of attorney for health care decisions or a health care proxy is a document you use to assign a person to make health care decisions for you in the event you cannot make them for yourself.

You should watch how much water and other liquids you get from food and drinks and avoid getting too much sodium, often from salt; potassium; and phosphorus. You may find it difficult to limit phosphorus because many foods that are high in phosphorus also provide the protein you need. Hemodialysis can remove protein from the body, so you should eat foods with high-quality protein, such as meat, fish, and eggs. Limit your phosphorus by avoiding foods such as beans, peas, nuts, tea, and colas. You may also need to take a pill called a phosphate binder that keeps phosphorus in your food from entering your bloodstream. Talk with your dialysis centers dietitian to find a hemodialysis meal plan that works for you.\n \nMore information about nutrition for people who are on hemodialysis is provided in the NIDDK health topic, Eat Right to Feel Right on Hemodialysis.\n \nPeritoneal Dialysis\n \nLike hemodialysis, peritoneal dialysis requires limits on sodium and phosphorus. You may need to take a phosphate binder. The liquid limitations in peritoneal dialysis may not be as strict as those for hemodialysis. In fact, you may need to drink more water and other liquids if your peritoneal dialysis treatments remove too much fluid from your body. Peritoneal dialysis removes potassium from the body, so you may need to eat potassium-rich foods such as potatoes, tomatoes, oranges, and bananas. However, be careful not to eat too much potassium because it can cause an unsteady heartbeat. Peritoneal dialysis removes even more protein than hemodialysis, so eating foods with high-quality protein is important. You may need to limit calories because your body absorbs sugar from the dialysis solution.\n \nKidney Transplantation\n \nKidney transplantation has the fewest restrictions on your diet. You should limit sodium because it can raise your blood pressure. Medicines that you take after the transplant can cause you to gain weight, so you may need to limit calories.\n \nConservative Management\n \nThe diet for conservative management limits protein. Protein breaks down into waste products the kidneys must remove. Limiting protein may reduce the amount of work the kidneys have to do so they will last longer.\n \n\n \nHemodialysis Peritoneal Dialysis Kidney Transplantation In Center Home CAPD CCPD Deceased Living Schedule Three treatments a week for 3 to 5 hours or more.

Hyperthyroidism is sometimes called thyrotoxicosis, the technical term for too much thyroid hormone in the blood. Thyroid hormones circulate throughout the body in the bloodstream and act on virtually every tissue and cell in the body. Hyperthyroidism causes many of the bodys functions to speed up. About 1 percent of the U.S. population has hyperthyroidism.1"} {"_id":"7af56606-b6fb-4169-b361-f5f7deb1c1ce","text":"The thyroid is a 2-inch-long, butterfly-shaped gland weighing less than 1 ounce. Located in the front of the neck below the larynx, or voice box, it has two lobes, one on each side of the windpipe. The thyroid is one of the glands that make up the endocrine system. The glands of the endocrine system produce, store, and release hormones into the bloodstream. The hormones then travel through the body and direct the activity of the bodys cells.\n \nThe thyroid gland makes two thyroid hormones, triiodothyronine (T3) and thyroxine (T4). T3 is made from T4 and is the more active hormone, directly affecting the tissues. Thyroid hormones affect metabolism, brain development, breathing, heart and nervous system functions, body temperature, muscle strength, skin dryness, menstrual cycles, weight, and cholesterol levels.\n \nThyroid hormone production is regulated by thyroid-stimulating hormone (TSH), which is made by the pituitary gland in the brain. When thyroid hormone levels in the blood are low, the pituitary releases more TSH. When thyroid hormone levels are high, the pituitary responds by decreasing TSH production."} {"_id":"a919ed37-f5d8-4ff2-b7f2-de6e48a6fbb8","text":"Hyperthyroidism has several causes, including\n \n- Graves disease - thyroid nodules - thyroiditis, or inflammation of the thyroid - consuming too much iodine - overmedicating with synthetic thyroid hormone, which is used to treat underactive thyroid\n \nRarely, hyperthyroidism is caused by a pituitary adenoma, which is a noncancerous tumor of the pituitary gland. In this case, hyperthyroidism is due to too much TSH.\n \nGraves Disease\n \nGraves disease, also known as toxic diffuse goiter, is the most common cause of hyperthyroidism in the United States. Graves disease is an autoimmune disorder. Normally, the immune system protects the body from infection by identifying and destroying bacteria, viruses, and other potentially harmful foreign substances. But in autoimmune diseases, the immune system attacks the bodys own cells and organs.\n \nWith Graves disease, the immune system makes an antibody called thyroid stimulating immunoglobulin (TSI) that attaches to thyroid cells. TSI mimics the action of TSH and stimulates the thyroid to make too much thyroid hormone.\n \nMore information is provided in the NIDDK health topic, Graves' disease.\n \nThyroid Nodules\n \nThyroid nodules, also called adenomas, are lumps in the thyroid. Thyroid nodules are common and usually noncancerous. About 3 to 7 percent of the U.S. population has them.2 However, nodules may become overactive and produce too much hormone.\n \nA single overactive nodule is called a toxic adenoma. Multiple overactive nodules are called toxic multinodular goiter. Often found in older adults, toxic multinodular goiter can produce a large amount of excess thyroid hormone.\n \nThyroiditis\n \nThyroiditis is an inflammation of the thyroid that causes stored thyroid hormone to leak out of the thyroid gland. At first, the leakage raises hormone levels in the blood, leading to hyperthyroidism that lasts for 1 or 2 months. Most people then develop hypothyroidismwhen thyroid hormone levels are too lowbefore the thyroid is completely healed.\n \nSeveral types of thyroiditis can cause hyperthyroidism followed by hypothyroidism:\n \n- Subacute thyroiditis. This condition involves painful inflammation and enlargement of the thyroid. Experts are not sure what causes subacute thyroiditis, but it may be related to a viral or bacterial infection. The condition usually goes away on its own in a few months. - Postpartum thyroiditis. This type of thyroiditis develops after a woman gives birth. For more information, see the section titled What happens with pregnancy and thyroid conditions? - Silent thyroiditis. This type of thyroiditis is called silent because it is painless, as is postpartum thyroiditis, even though the thyroid may be enlarged. Like postpartum thyroiditis, silent thyroiditis is probably an autoimmune condition and sometimes develops into permanent hypothyroidism.\n \nConsuming Too Much Iodine\n \nThe thyroid uses iodine to make thyroid hormone, so the amount of iodine consumed influences the amount of thyroid hormone the thyroid makes. In some people, consuming large amounts of iodine may cause the thyroid to make excess thyroid hormone.\n \nSometimes significant amounts of iodine are contained in medicationssuch as amiodarone, which is used to treat heart problemsor in supplements containing seaweed. Some cough syrups also contain large amounts of iodine. See Eating, Diet, and Nutrition for more information on iodine.\n \nOvermedicating with Synthetic Thyroid Hormone\n \nSome people who take synthetic thyroid hormone for hypothyroidism may take too much. People who take synthetic thyroid hormone should see their health care provider at least once a year to have their thyroid hormone levels checked and follow the health care providers instructions about the dosage.\n \nSome other medications may also interact with synthetic thyroid hormone to raise hormone levels in the blood. People who take synthetic thyroid hormone should ask their health care provider about interactions when starting new medications."} {"_id":"105c4a87-8367-41f6-bfcc-b5b7f6bba4fd","text":"Hyperthyroidism has many symptoms that can vary from person to person.

With suspected hyperthyroidism, health care providers take a medical history and perform a thorough physical exam. Health care providers may then use several blood tests, such as the following, to confirm a diagnosis of hyperthyroidism and find its cause:\n \nTSH test. The ultrasensitive TSH test is usually the first test a health care provider performs. This test detects even tiny amounts of TSH in the blood and is the most accurate measure of thyroid activity available. The TSH test is especially useful in detecting mild hyperthyroidism. Generally, a TSH reading below normal means a person has hyperthyroidism and a reading above normal means a person has hypothyroidism.\n \nHealth care providers may conduct additional tests to help confirm the diagnosis or determine the cause of hyperthyroidism.\n \nT3 and T4 test. This test shows the levels of T3 and T4 in the blood. With hyperthyroidism, the levels of one or both of these hormones in the blood are higher than normal.\n \nThyroid-stimulating immunoglobulin (TSI) test. This test, also called a thyroidstimulating antibody test, measures the level of TSI in the blood. Most people with Graves disease have this antibody, but people whose hyperthyroidism is caused by other conditions do not.\n \nRadioactive iodine uptake test. The radioactive iodine uptake test measures the amount of iodine the thyroid collects from the bloodstream. Measuring the amount of iodine in a persons thyroid helps the health care provider determine what is causing a persons hyperthyroidism. For example, low levels of iodine uptake might be a sign of thyroiditis, whereas high levels could indicate Graves disease.\n \nThyroid scan. A thyroid scan shows how and where iodine is distributed in the thyroid. The images of nodules and other possible irregularities help the health care provider diagnose the cause of a persons hyperthyroidism.\n \nMore information is provided in the NIDDK health topic, Thyroid Tests."} {"_id":"eabbd650-5b22-4ccc-8740-5bc2a0c3c55e","text":"Health care providers treat hyperthyroidism with medications, radioiodine therapy, or thyroid surgery. The aim of treatment is to bring thyroid hormone levels to a normal state, thus preventing long-term complications, and to relieve uncomfortable symptoms. No single treatment works for everyone.\n \nTreatment depends on the cause of hyperthyroidism and how severe it is. When choosing a treatment, health care providers consider a patients age, possible allergies to or side effects of the medications, other conditions such as pregnancy or heart disease, and the availability of an experienced thyroid surgeon.\n \nFinding the right specialist for treatment is an important first step. Some professional societies, listed under For More Information, and endocrinology departments in local teaching hospitals can provide the names of local specialists.\n \nMedications\n \nBeta blockers. Health care providers may prescribe a medication called a beta blocker to reduce symptoms until other treatments take effect. Beta blockers act quickly to relieve many of the symptoms of hyperthyroidism, such as tremors, rapid heartbeat, and nervousness, but do not stop thyroid hormone production. Most people feel better within hours of taking these medications.\n \nAntithyroid medications. Antithyroid therapy is the easiest way to treat hyperthyroidism. Antithyroid medications interfere with thyroid hormone production but dont usually have permanent results. Antithyroid medications are not used to treat thyroiditis.\n \nOnce treatment with antithyroid medications begins, thyroid hormone levels may not move into the normal range for several weeks or months. The average treatment time is about 1 to 2 years, but treatment can continue for many years.\n \nAntithyroid medications can cause side effects in some people, including\n \n- allergic reactions such as rashes and itching - a decrease in the number of white blood cells in the body, which can lower resistance to infection - liver failure, in rare cases\n \nStop your antithyroid medication and call your health care provider right away if you develop any of the following while taking antithyroid medications: - fatigue - weakness - vague abdominal pain - loss of appetite - skin rash or itching - easy bruising - yellowing of the skin or whites of the eyes, called jaundice - persistent sore throat - fever\n \nIn the United States, health care providers prescribe the antithyroid medication methimazole (Tapazole, Northyx) for most types of hyperthyroidism.\n \nAntithyroid medications and pregnancy. Because pregnant and breastfeeding women cannot receive radioiodine therapy, they are usually treated with an antithyroid medication instead. However, experts agree that women in their first trimester of pregnancy should not take methimazole due to the rare occurrence of damage to the fetus. Another antithyroid medication, propylthiouracil (PTU), is available for women in this stage of pregnancy or for women who are allergic to or intolerant of methimazole and have no other treatment options.\n \nHealth care providers may prescribe PTU for the first trimester of pregnancy and switch to methimazole for the second and third trimesters. Some women are able to stop taking antithyroid medications in the last 4 to 8 weeks of pregnancy due to the remission of hyperthyroidism that occurs during pregnancy. However these women should continue to be monitored for recurrence of thyroid problems following delivery.\n \nStudies have shown that mothers taking antithyroid medications may safely breastfeed. However, they should take only moderate doses, less than 1020 milligrams daily, of the antithyroid medication methimazole. Doses should be divided and taken after feedings, and the infants should be monitored for side effects.4\n \nWomen requiring higher doses of the antithyroid medication to control hyperthyroidism should not breastfeed.\n \nRadioiodine Therapy\n \nRadioactive iodine-131 is a common and effective treatment for hyperthyroidism. In radioiodine therapy, patients take radioactive iodine-131 by mouth. Because the thyroid gland collects iodine to make thyroid hormone, it will collect the radioactive iodine from the bloodstream in the same way. The radioactive iodine gradually destroys the cells that make up the thyroid gland but does not affect other body tissues.\n \nMore than one round of radioiodine therapy may be needed to bring thyroid hormone production into the normal range. In the meantime, treatment with beta blockers can control symptoms.\n \nAlmost everyone who receives radioactive iodine treatment eventually develops hypothyroidism. But health care providers consider this an acceptable outcome because hypothyroidism is easier to treat and has fewer long-term complications than hyperthyroidism. People who develop hypothyroidism must take synthetic thyroid hormone.\n \nRadioiodine and pregnancy. Although iodine-131 is not known to cause birth defects or infertility, radioiodine therapy is not used in pregnant women or women who are breastfeeding. Radioactive iodine can be harmful to the fetus thyroid and can be passed from mother to child in breast milk. Experts recommend that women wait a year after treatment before becoming pregnant.\n \nThyroid Surgery\n \nThe least-used treatment is surgery to remove part or most of the thyroid gland. Sometimes surgery may be used to treat\n \n- pregnant women who cannot tolerate antithyroid medications - people with large goiters - people who have cancerous thyroid nodules, though hyperthyroidism does not cause cancer\n \nBefore surgery, the health care provider may prescribe antithyroid medications to temporarily bring a patients thyroid hormone levels into the normal range. This presurgical treatment prevents a condition called thyroid storma sudden, severe worsening of symptomsthat can occur when hyperthyroid patients have general anesthesia.\n \nWhen part of the thyroid is removedas a treatment for toxic nodules, for examplethyroid hormone levels may return to normal. But some surgical patients may still develop hypothyroidism and need to take synthetic thyroxine, a medication that is identical to the hormone, T4, made by the thyroid. If the entire thyroid is removed, lifelong thyroid hormone medication is necessary. After surgery, health care providers will continue to monitor patients thyroid hormone levels.\n \nAlthough uncommon, certain problems can occur in thyroid surgery. The parathyroid glands can be damaged because they are located very close to the thyroid. These glands help control calcium and phosphorus levels in the body. Damage to the laryngeal nerve, also located close to the thyroid, can lead to voice changes or breathing problems. But when surgery is performed by an experienced surgeon, less than 1 percent of patients have permanent complications.5 People who need help finding a surgeon can contact one of the organizations listed under For More Information."} {"_id":"459273fc-5e4c-4aa8-9185-5152a0dd288a","text":"Experts recommend that people eat a balanced diet to obtain most nutrients.

A person with kidney failure may have the following symptoms: - little or no urination - edemaswelling, usually in the legs, feet, or ankles and less often in the hands or face - drowsiness - fatigue, or feeling tired - generalized itching or numbness - dry skin - headaches - weight loss - appetite loss - nausea - vomiting - sleep problems - trouble concentrating - darkened skin - muscle cramps - shortness of breath - chest pain\n \nUntreated kidney failure can lead to coma and death. More than half of people with autosomal dominant PKD progress to kidney failure by age 70.1\n \n- UTIs. Kidney cysts block the flow of urine through the kidneys. Stagnant urine can set the stage for infection. Bacteria enter the urinary tract through the urethra and spread up to the kidneys. Sometimes, the kidney cysts become infected. UTIs may cause scarring in the kidneys. - Kidney stones. About 20 percent of people with autosomal dominant PKD have kidney stones.1 Kidney stones can block the flow of urine and cause pain. - Liver cysts. Liver cysts are the most common nonkidney complication of autosomal dominant PKD.1 Liver cysts generally cause no symptoms. - Pancreatic cysts. PKD can also cause cysts in the pancreas. Pancreatic cysts rarely cause pancreatitisinflammation, or swelling, of the pancreas. - Abnormal heart valves. Abnormal heart valves may occur in up to 25 percent of people with autosomal dominant PKD.1 Insufficient blood flow in the aortathe large artery that carries blood from the heartmay result from the abnormal heart valves. - Diverticula. Diverticula are small pouches, or sacs, that push outward through weak spots in the colon wall. This complication is more common in people with PKD who have kidney failure.1 - Brain aneurysms. An aneurysm is a bulge in the wall of a blood vessel. Aneurysms in the brain might cause headaches that are severe or feel different from other headaches. Brain aneurysms can rupture, or break open, causing bleeding inside the skull. A ruptured aneurysm in the brain is a life-threatening condition and requires immediate medical attention."} {"_id":"92c0fc60-4dc5-4e98-90fc-872a35fb6198","text":"Autosomal recessive PKD is a rare genetic disorder that affects the liver as well as the kidneys. The signs of autosomal recessive PKD frequently appear in the earliest months of life, even in the womb, so health care providers often call it infantile PKD. In an autosomal recessive disorder, the child has to inherit the gene mutation from both parents to have an increased likelihood for the disorder. The chance of a child inheriting autosomal recessive mutations from both parents with a gene mutation is 25 percent, or one in four. If only one parent carries the mutated gene, the child will not get the disorder, although the child may inherit the gene mutation. The child is a carrier of the disorder and can pass the gene mutation to the next generation. Genetic testing can show whether a parent or child is a carrier of the mutated gene. Autosomal recessive disorders do not typically appear in every generation of an affected family.\n \nThe following chart shows the chance of inheriting an autosomal recessive mutation from parents who both carry the mutated gene:\n \n\n \n\n \nRead more about how people inherit genetic conditions at the NLMs Genetics Home Reference."} {"_id":"177880a2-8ec9-4f25-8700-f829fcb96b68","text":"An early sign of autosomal recessive PKD is an enlarged kidney, seen in a fetus or an infant using ultrasound.

People with diabetes have high blood glucose, also called high blood sugar or hyperglycemia.\n \nDiabetes is a disorder of metabolismthe way the body uses digested food for energy. The digestive tract breaks down carbohydratessugars and starches found in many foodsinto glucose, a form of sugar that enters the bloodstream. With the help of the hormone insulin, cells throughout the body absorb glucose and use it for energy. Diabetes develops when the body doesnt make enough insulin or is not able to use insulin effectively, or both.\n \nInsulin is made in the pancreas, an organ located behind the stomach. The pancreas contains clusters of cells called islets. Beta cells within the islets make insulin and release it into the blood.\n \nIf beta cells dont produce enough insulin, or the body doesnt respond to the insulin that is present, glucose builds up in the blood instead of being absorbed by cells in the body, leading to prediabetes or diabetes. Prediabetes is a condition in which blood glucose levels or A1C levelswhich reflect average blood glucose levelsare higher than normal but not high enough to be diagnosed as diabetes. In diabetes, the bodys cells are starved of energy despite high blood glucose levels.\n \nOver time, high blood glucose damages nerves and blood vessels, leading to complications such as heart disease, stroke, kidney disease, blindness, dental disease, and amputations. Other complications of diabetes may include increased susceptibility to other diseases, loss of mobility with aging, depression, and pregnancy problems. No one is certain what starts the processes that cause diabetes, but scientists believe genes and environmental factors interact to cause diabetes in most cases.\n \nThe two main types of diabetes are type 1 diabetes and type 2 diabetes. A third type, gestational diabetes, develops only during pregnancy. Other types of diabetes are caused by defects in specific genes, diseases of the pancreas, certain drugs or chemicals, infections, and other conditions. Some people show signs of both type 1 and type 2 diabetes."} {"_id":"5390bc39-5890-4f3a-884e-4b9b8f61ac35","text":"Type 1 diabetes is caused by a lack of insulin due to the destruction of insulin-producing beta cells in the pancreas. In type 1 diabetesan autoimmune diseasethe bodys immune system attacks and destroys the beta cells. Normally, the immune system protects the body from infection by identifying and destroying bacteria, viruses, and other potentially harmful foreign substances. But in autoimmune diseases, the immune system attacks the bodys own cells. In type 1 diabetes, beta cell destruction may take place over several years, but symptoms of the disease usually develop over a short period of time.\n \nType 1 diabetes typically occurs in children and young adults, though it can appear at any age. In the past, type 1 diabetes was called juvenile diabetes or insulin-dependent diabetes mellitus.\n \nLatent autoimmune diabetes in adults (LADA) may be a slowly developing kind of type 1 diabetes. Diagnosis usually occurs after age 30. In LADA, as in type 1 diabetes, the bodys immune system destroys the beta cells. At the time of diagnosis, people with LADA may still produce their own insulin, but eventually most will need insulin shots or an insulin pump to control blood glucose levels.\n \nGenetic Susceptibility\n \nHeredity plays an important part in determining who is likely to develop type 1 diabetes. Genes are passed down from biological parent to child. Genes carry instructions for making proteins that are needed for the bodys cells to function. Many genes, as well as interactions among genes, are thought to influence susceptibility to and protection from type 1 diabetes. The key genes may vary in different population groups. Variations in genes that affect more than 1 percent of a population group are called gene variants.\n \nCertain gene variants that carry instructions for making proteins called human leukocyte antigens (HLAs) on white blood cells are linked to the risk of developing type 1 diabetes. The proteins produced by HLA genes help determine whether the immune system recognizes a cell as part of the body or as foreign material. Some combinations of HLA gene variants predict that a person will be at higher risk for type 1 diabetes, while other combinations are protective or have no effect on risk.\n \nWhile HLA genes are the major risk genes for type 1 diabetes, many additional risk genes or gene regions have been found. Not only can these genes help identify people at risk for type 1 diabetes, but they also provide important clues to help scientists better understand how the disease develops and identify potential targets for therapy and prevention.\n \nGenetic testing can show what types of HLA genes a person carries and can reveal other genes linked to diabetes. However, most genetic testing is done in a research setting and is not yet available to individuals. Scientists are studying how the results of genetic testing can be used to improve type 1 diabetes prevention or treatment.\n \nAutoimmune Destruction of Beta Cells\n \nIn type 1 diabetes, white blood cells called T cells attack and destroy beta cells. The process begins well before diabetes symptoms appear and continues after diagnosis. Often, type 1 diabetes is not diagnosed until most beta cells have already been destroyed. At this point, a person needs daily insulin treatment to survive. Finding ways to modify or stop this autoimmune process and preserve beta cell function is a major focus of current scientific research.\n \nRecent research suggests insulin itself may be a key trigger of the immune attack on beta cells. The immune systems of people who are susceptible to developing type 1 diabetes respond to insulin as if it were a foreign substance, or antigen. To combat antigens, the body makes proteins called antibodies. Antibodies to insulin and other proteins produced by beta cells are found in people with type 1 diabetes. Researchers test for these antibodies to help identify people at increased risk of developing the disease. Testing the types and levels of antibodies in the blood can help determine whether a person has type 1 diabetes, LADA, or another type of diabetes.\n \nEnvironmental Factors\n \nEnvironmental factors, such as foods, viruses, and toxins, may play a role in the development of type 1 diabetes, but the exact nature of their role has not been determined. Some theories suggest that environmental factors trigger the autoimmune destruction of beta cells in people with a genetic susceptibility to diabetes. Other theories suggest that environmental factors play an ongoing role in diabetes, even after diagnosis.\n \nViruses and infections. A virus cannot cause diabetes on its own, but people are sometimes diagnosed with type 1 diabetes during or after a viral infection, suggesting a link between the two. Also, the onset of type 1 diabetes occurs more frequently during the winter when viral infections are more common. Viruses possibly associated with type 1 diabetes include coxsackievirus B, cytomegalovirus, adenovirus, rubella, and mumps. Scientists have described several ways these viruses may damage or destroy beta cells or possibly trigger an autoimmune response in susceptible people. For example, anti-islet antibodies have been found in patients with congenital rubella syndrome, and cytomegalovirus has been associated with significant beta cell damage and acute pancreatitisinflammation of the pancreas. Scientists are trying to identify a virus that can cause type 1 diabetes so that a vaccine might be developed to prevent the disease.\n \nInfant feeding practices. Some studies have suggested that dietary factors may raise or lower the risk of developing type 1 diabetes. For example, breastfed infants and infants receiving vitamin D supplements may have a reduced risk of developing type 1 diabetes, while early exposure to cows milk and cereal proteins may increase risk. More research is needed to clarify how infant nutrition affects the risk for type 1 diabetes.\n \nRead more in the Centers for Disease Control and Preventions (CDCs) publication National Diabetes Statistics Report, 2014 at www.cdc.gov for information about research studies related to type 1 diabetes."} {"_id":"ac158051-9cdf-4c40-bdce-50c3d4588605","text":"Type 2 diabetesthe most common form of diabetesis caused by a combination of factors, including insulin resistance, a condition in which the bodys muscle, fat, and liver cells do not use insulin effectively. Type 2 diabetes develops when the body can no longer produce enough insulin to compensate for the impaired ability to use insulin. Symptoms of type 2 diabetes may develop gradually and can be subtle; some people with type 2 diabetes remain undiagnosed for years.\n \nType 2 diabetes develops most often in middle-aged and older people who are also overweight or obese. The disease, once rare in youth, is becoming more common in overweight and obese children and adolescents. Scientists think genetic susceptibility and environmental factors are the most likely triggers of type 2 diabetes.\n \nGenetic Susceptibility\n \nGenes play a significant part in susceptibility to type 2 diabetes. Having certain genes or combinations of genes may increase or decrease a persons risk for developing the disease. The role of genes is suggested by the high rate of type 2 diabetes in families and identical twins and wide variations in diabetes prevalence by ethnicity. Type 2 diabetes occurs more frequently in African Americans, Alaska Natives, American Indians, Hispanics\/Latinos, and some Asian Americans, Native Hawaiians, and Pacific Islander Americans than it does in non-Hispanic whites.\n \nRecent studies have combined genetic data from large numbers of people, accelerating the pace of gene discovery. Though scientists have now identified many gene variants that increase susceptibility to type 2 diabetes, the majority have yet to be discovered. The known genes appear to affect insulin production rather than insulin resistance. Researchers are working to identify additional gene variants and to learn how they interact with one another and with environmental factors to cause diabetes.\n \nStudies have shown that variants of the TCF7L2 gene increase susceptibility to type 2 diabetes. For people who inherit two copies of the variants, the risk of developing type 2 diabetes is about 80 percent higher than for those who do not carry the gene variant.1 However, even in those with the variant, diet and physical activity leading to weight loss help delay diabetes, according to the Diabetes Prevention Program (DPP), a major clinical trial involving people at high risk.\n \nGenes can also increase the risk of diabetes by increasing a persons tendency to become overweight or obese. One theory, known as the thrifty gene hypothesis, suggests certain genes increase the efficiency of metabolism to extract energy from food and store the energy for later use. This survival trait was advantageous for populations whose food supplies were scarce or unpredictable and could help keep people alive during famine. In modern times, however, when high-calorie foods are plentiful, such a trait can promote obesity and type 2 diabetes.\n \nObesity and Physical Inactivity\n \nPhysical inactivity and obesity are strongly associated with the development of type 2 diabetes. People who are genetically susceptible to type 2 diabetes are more vulnerable when these risk factors are present.\n \nAn imbalance between caloric intake and physical activity can lead to obesity, which causes insulin resistance and is common in people with type 2 diabetes. Central obesity, in which a person has excess abdominal fat, is a major risk factor not only for insulin resistance and type 2 diabetes but also for heart and blood vessel disease, also called cardiovascular disease (CVD). This excess belly fat produces hormones and other substances that can cause harmful, chronic effects in the body such as damage to blood vessels.\n \nThe DPP and other studies show that millions of people can lower their risk for type 2 diabetes by making lifestyle changes and losing weight. The DPP proved that people with prediabetesat high risk of developing type 2 diabetescould sharply lower their risk by losing weight through regular physical activity and a diet low in fat and calories. In 2009, a follow-up study of DPP participantsthe Diabetes Prevention Program Outcomes Study (DPPOS)showed that the benefits of weight loss lasted for at least 10 years after the original study began.2\n \nRead more about the DPP, funded under National Institutes of Health (NIH) clinical trial number NCT00004992, and the DPPOS, funded under NIH clinical trial number NCT00038727 in Diabetes Prevention Program.\n \nInsulin Resistance\n \nInsulin resistance is a common condition in people who are overweight or obese, have excess abdominal fat, and are not physically active. Muscle, fat, and liver cells stop responding properly to insulin, forcing the pancreas to compensate by producing extra insulin. As long as beta cells are able to produce enough insulin, blood glucose levels stay in the normal range. But when insulin production falters because of beta cell dysfunction, glucose levels rise, leading to prediabetes or diabetes.\n \nAbnormal Glucose Production by the Liver\n \nIn some people with diabetes, an abnormal increase in glucose production by the liver also contributes to high blood glucose levels. Normally, the pancreas releases the hormone glucagon when blood glucose and insulin levels are low. Glucagon stimulates the liver to produce glucose and release it into the bloodstream. But when blood glucose and insulin levels are high after a meal, glucagon levels drop, and the liver stores excess glucose for later, when it is needed. For reasons not completely understood, in many people with diabetes, glucagon levels stay higher than needed. High glucagon levels cause the liver to produce unneeded glucose, which contributes to high blood glucose levels. Metformin, the most commonly used drug to treat type 2 diabetes, reduces glucose production by the liver.\n \nThe Roles of Insulin and Glucagon in Normal Blood Glucose Regulation\n \nA healthy persons body keeps blood glucose levels in a normal range through several complex mechanisms. Insulin and glucagon, two hormones made in the pancreas, help regulate blood glucose levels:\n \n- Insulin, made by beta cells, lowers elevated blood glucose levels. - Glucagon, made by alpha cells, raises low blood glucose levels.\n \n- Insulin helps muscle, fat, and liver cells absorb glucose from the bloodstream, lowering blood glucose levels. - Insulin stimulates the liver and muscle tissue to store excess glucose. The stored form of glucose is called glycogen. - Insulin also lowers blood glucose levels by reducing glucose production in the liver.\n \n- Glucagon signals the liver and muscle tissue to break down glycogen into glucose, which enters the bloodstream and raises blood glucose levels. - If the body needs more glucose, glucagon stimulates the liver to make glucose from amino acids.\n \nMetabolic Syndrome\n \nMetabolic syndrome, also called insulin resistance syndrome, refers to a group of conditions common in people with insulin resistance, including\n \n- higher than normal blood glucose levels - increased waist size due to excess abdominal fat - high blood pressure - abnormal levels of cholesterol and triglycerides in the blood\n \nCell Signaling and Regulation\n \nCells communicate through a complex network of molecular signaling pathways. For example, on cell surfaces, insulin receptor molecules capture, or bind, insulin molecules circulating in the bloodstream. This interaction between insulin and its receptor prompts the biochemical signals that enable the cells to absorb glucose from the blood and use it for energy.\n \nProblems in cell signaling systems can set off a chain reaction that leads to diabetes or other diseases. Many studies have focused on how insulin signals cells to communicate and regulate action. Researchers have identified proteins and pathways that transmit the insulin signal and have mapped interactions between insulin and body tissues, including the way insulin helps the liver control blood glucose levels. Researchers have also found that key signals also come from fat cells, which produce substances that cause inflammation and insulin resistance.\n \nThis work holds the key to combating insulin resistance and diabetes. As scientists learn more about cell signaling systems involved in glucose regulation, they will have more opportunities to develop effective treatments.\n \nBeta Cell Dysfunction\n \nScientists think beta cell dysfunction is a key contributor to type 2 diabetes. Beta cell impairment can cause inadequate or abnormal patterns of insulin release. Also, beta cells may be damaged by high blood glucose itself, a condition called glucose toxicity.\n \nScientists have not determined the causes of beta cell dysfunction in most cases. Single gene defects lead to specific forms of diabetes called maturity-onset diabetes of the young (MODY). The genes involved regulate insulin production in the beta cells. Although these forms of diabetes are rare, they provide clues as to how beta cell function may be affected by key regulatory factors. Other gene variants are involved in determining the number and function of beta cells. But these variants account for only a small percentage of type 2 diabetes cases. Malnutrition early in life is also being investigated as a cause of beta cell dysfunction. The metabolic environment of the developing fetus may also create a predisposition for diabetes later in life.\n \nRisk Factors for Type 2 Diabetes\n \nPeople who develop type 2 diabetes are more likely to have the following characteristics:\n \n- age 45 or older - overweight or obese - physically inactive - parent or sibling with diabetes - family background that is African American, Alaska Native, American Indian, Asian American, Hispanic\/Latino, or Pacific Islander American - history of giving birth to a baby weighing more than 9 pounds - history of gestational diabetes - high blood pressure140\/90 or aboveor being treated for high blood pressure - high-density lipoprotein (HDL), or good, cholesterol below 35 milligrams per deciliter (mg\/dL), or a triglyceride level above 250 mg\/dL - polycystic ovary syndrome, also called PCOS - prediabetesan A1C level of 5.7 to 6.4 percent; a fasting plasma glucose test result of 100125 mg\/dL, called impaired fasting glucose; or a 2-hour oral glucose tolerance test result of 140199, called impaired glucose tolerance - acanthosis nigricans, a condition associated with insulin resistance, characterized by a dark, velvety rash around the neck or armpits - history of CVD\n \nThe American Diabetes Association (ADA) recommends that testing to detect prediabetes and type 2 diabetes be considered in adults who are overweight or obese and have one or more additional risk factors for diabetes. In adults without these risk factors, testing should begin at age 45."} {"_id":"cb42b828-1df4-4194-9338-fefbf2b906df","text":"Insulin Resistance and Beta Cell Dysfunction\n \nHormones produced by the placenta and other pregnancy-related factors contribute to insulin resistance, which occurs in all women during late pregnancy. Insulin resistance increases the amount of insulin needed to control blood glucose levels. If the pancreas cant produce enough insulin due to beta cell dysfunction, gestational diabetes occurs.\n \nAs with type 2 diabetes, excess weight is linked to gestational diabetes. Overweight or obese women are at particularly high risk for gestational diabetes because they start pregnancy with a higher need for insulin due to insulin resistance. Excessive weight gain during pregnancy may also increase risk.\n \nFamily History\n \nHaving a family history of diabetes is also a risk factor for gestational diabetes, suggesting that genes play a role in its development. Genetics may also explain why the disorder occurs more frequently in African Americans, American Indians, and Hispanics\/Latinos. Many gene variants or combinations of variants may increase a womans risk for developing gestational diabetes. Studies have found several gene variants associated with gestational diabetes, but these variants account for only a small fraction of women with gestational diabetes.\n \nFuture Risk of Type 2 Diabetes\n \nBecause a womans hormones usually return to normal levels soon after giving birth, gestational diabetes disappears in most women after delivery. However, women who have gestational diabetes are more likely to develop gestational diabetes with future pregnancies and develop type 2 diabetes.3 Women with gestational diabetes should be tested for persistent diabetes 6 to 12 weeks after delivery and at least every 3 years thereafter.\n \nAlso, exposure to high glucose levels during gestation increases a childs risk for becoming overweight or obese and for developing type 2 diabetes later on. The result may be a cycle of diabetes affecting multiple generations in a family.

Scientists believe genes and environmental factors interact to cause diabetes in most cases. - People with diabetes have high blood glucose, also called high blood sugar or hyperglycemia. Diabetes develops when the body doesnt make enough insulin or is not able to use insulin effectively, or both. - Insulin is a hormone made by beta cells in the pancreas. Insulin helps cells throughout the body absorb and use glucose for energy. If the body does not produce enough insulin or cannot use insulin effectively, glucose builds up in the blood instead of being absorbed by cells in the body, and the body is starved of energy. - Prediabetes is a condition in which blood glucose levels or A1C levels are higher than normal but not high enough to be diagnosed as diabetes. People with prediabetes can substantially reduce their risk of developing diabetes by losing weight and increasing physical activity. - The two main types of diabetes are type 1 diabetes and type 2 diabetes. Gestational diabetes is a third form of diabetes that develops only during pregnancy. - Type 1 diabetes is caused by a lack of insulin due to the destruction of insulin-producing beta cells. In type 1 diabetesan autoimmune diseasethe bodys immune system attacks and destroys the beta cells. - Type 2 diabetesthe most common form of diabetesis caused by a combination of factors, including insulin resistance, a condition in which the bodys muscle, fat, and liver cells do not use insulin effectively.

A dipstick test performed on a urine sample can detect the presence of albumin in the urine, which could mean kidney damage. The child or a caretaker collects a urine sample in a special container. For the test, a nurse or technician places a strip of chemically treated paper, called a dipstick, into the childs urine sample. Patches on the dipstick change color when albumin is present in urine.\n \nUrine albumin-to-creatinine ratio. A health care provider uses this measurement to estimate the amount of albumin passed into the urine over a 24-hour period. The child provides a urine sample during an appointment with the health care provider. Creatinine is a waste product filtered in the kidneys and passed in the urine. A high urine albumin-to-creatinine ratio indicates that the kidneys are leaking large amounts of albumin into the urine.\n \nBlood Test\n \nA blood test involves drawing blood at a health care providers office or a commercial facility and sending the sample to a lab for analysis. The lab tests the sample to estimate how much blood the kidneys filter each minute, called the estimated glomerular filtration rate, or eGFR. The test results help the health care provider determine the amount of kidney damage. Health care providers may also order other blood tests to help determine the underlying disease that may be causing childhood nephrotic syndrome.\n \nUltrasound of the Kidney\n \nUltrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. A specially trained technician performs the procedure in a health care providers office, an outpatient center, or a hospital. A radiologista doctor who specializes in medical imaginginterprets the images to see if the kidneys look normal; a child does not need anesthesia.\n \nKidney Biopsy\n \nBiopsy is a procedure that involves taking a small piece of kidney tissue for examination with a microscope.

Corticosteroids are a group of medications that reduce the activity of the immune system, decrease the amount of albumin lost in the urine, and decrease swelling. Health care providers commonly use prednisone or a related corticosteroid to treat idiopathic childhood nephrotic syndrome. About 90 percent of children achieve remission with daily corticosteroids for 6 weeks and then a slightly smaller dose every other day for 6 weeks.2 Remission is a period when the child is symptom-free. Many children relapse after initial therapy, and health care providers treat them with a shorter course of corticosteroids until the disease goes into remission again. Children may have multiple relapses; however, they most often recover without long-term kidney damage. When a child has frequent relapses or does not respond to treatment, a health care provider may prescribe other medications that reduce the activity of the immune system. These medications prevent the body from making antibodies that can damage kidney tissues. They include - cyclophosphamide - mycophenolate (CellCept, Myfortic) - cyclosporine - tacrolimus (Hecoria, Prograf) A health care provider may use these other immune system medications with corticosteroids or in place of corticosteroids. - Remove extra fluid. A health care provider may prescribe a diuretic, a medication that helps the kidneys remove extra fluid from the blood. Removing the extra fluid can often help to lower blood pressure. - Lower blood pressure. Some children with childhood nephrotic syndrome develop high blood pressure and may need to take additional medications to lower their blood pressure. Two types of blood pressure-lowering medications, angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, have the additional benefit of slowing the progression of kidney disease. Many children with nephrotic syndrome require two or more medications to control their blood pressure.\n \nSecondary Childhood Nephrotic Syndrome\n \nHealth care providers treat secondary childhood nephrotic syndrome by treating the underlying cause of the primary illness.

Researchers have discovered abnormal genes responsible for the inherited forms of the disease. More often, however, classical distal RTA occurs as a result of systemic diseasesdiseases that affect many organ systemslike the autoimmune disorders Sjgren's syndrome and lupus, which also attack the distal tubule.\n \nOther diseases and conditions associated with classical distal RTA include sickle cell anemia, hyperparathyroidism, hyperthyroidism, chronic active hepatitis, primary biliary cirrhosis, a hereditary form of deafness, analgesic nephropathy, rejection of a transplanted kidney, renal medullary cystic disease, obstructive uropathy, and chronic urinary tract infections. Many of these conditions cause abnormal calcium deposits to build up in the kidney and impair distal tubule function.\n \nA major consequence of classical distal RTA is a low blood potassium level. The level drops if the kidneys excrete too much potassium into urine instead of returning it to the blood supply. Because potassium helps regulate nerve and muscle health and heart rate, low levels can cause extreme weakness, irregular heartbeat, paralysis, and even death.\n \nUntreated classical distal RTA causes growth retardation in children and progressive kidney and bone disease in adults. Restoring normal growth and preventing kidney stones are the major goals of therapy. If acidosis is corrected with sodium bicarbonate or sodium citrate, then low blood-potassium, salt depletion, and calcium leakage into urine will be corrected. This alkali therapy also helps decrease the development of kidney stones and stabilizes kidney function so kidney failure does not progress. Infants may need potassium supplements, but older children and adults rarely do because alkali therapy prevents the kidney from excreting potassium into the urine.\n \nType 2: Proximal RTA\n \nType 2 is also called proximal RTA. The word \"proximal,\" which means near, indicates that the defect is closer to the point where fluid and wastes from the blood enter the tubule.\n \nThis form of RTA occurs most frequently in children as part of a disorder called Fanconi's syndrome. The features of Fanconi's syndrome include the abnormal excretion of glucose, amino acids, citrate, and phosphate into the urine, as well as vitamin D deficiency and low blood-potassium.\n \nProximal RTA can also result from inherited disorders that disrupt the body's normal breakdown and use of nutrients. Examples include the rare disease cystinosis, in which cystine crystals are deposited in bones and other tissues; hereditary fructose intolerance; and Wilson disease.\n \nProximal RTA also occurs in patients treated with ifosfamide, a drug used in chemotherapy. A few older drugssuch as acetazolamide or outdated tetracyclinecan also cause proximal RTA. In adults, proximal RTA may complicate diseases like multiple myeloma, or it may occur in people who experience chronic rejection of a transplanted kidney.\n \nWhen possible, identifying and correcting the underlying causes are important steps in treating the acquired forms of proximal RTA. The diagnosis is based on the chemical analysis of blood and urine samples. Children with this disorder would likely receive large doses of an oral alkali, such as sodium bicarbonate or potassium citrate, to treat acidosis and prevent bone disorders, kidney stones, and growth failure.

Aldosterone directs the kidneys to regulate the levels of sodium, potassium, and chloride in the blood. Type 4 RTA also occurs when the tubule transport of electrolytes such as sodium, chloride, and potassium is impaired due to an inherited disorder or the use of certain drugs.\n \nDrugs that may cause type 4 RTA include\n \n- diuretics used to treat congestive heart failure such as spironolactone or eplerenone - blood pressure drugs called angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs) - the antibiotic trimethoprim - the antibiotic pentamidine, which is used to treat pneumonia - an agent called heparin that keeps blood from clotting - a class of painkillers called nonsteroidal anti-inflammatory drugs (NSAIDs) - some immunosuppressive drugs used to prevent rejection\n \nType 4 RTA may also result from diseases that alter kidney structure and function such as diabetic nephropathy, HIV\/AIDS, Addison's disease, sickle cell disease, urinary tract obstruction, lupus, amyloidosis, removal or destruction of both adrenal glands, and kidney transplant rejection.\n \nFor people who produce aldosterone but cannot use it, researchers have identified the genetic basis for their body's resistance to the hormone.

The first occurs early in puberty, when the prostate doubles in size. The second phase of growth begins around age 25 and continues during most of a mans life. Benign prostatic hyperplasia often occurs with the second growth phase.\n \nAs the prostate enlarges, the gland presses against and pinches the urethra. The bladder wall becomes thicker.

For this reason, some researchers believe factors related to aging and the testicles may cause benign prostatic hyperplasia.\n \nThroughout their lives, men produce testosterone, a male hormone, and small amounts of estrogen, a female hormone. As men age, the amount of active testosterone in their blood decreases, which leaves a higher proportion of estrogen. Scientific studies have suggested that benign prostatic hyperplasia may occur because the higher proportion of estrogen within the prostate increases the activity of substances that promote prostate cell growth.\n \nAnother theory focuses on dihydrotestosterone (DHT), a male hormone that plays a role in prostate development and growth. Some research has indicated that even with a drop in blood testosterone levels, older men continue to produce and accumulate high levels of DHT in the prostate. This accumulation of DHT may encourage prostate cells to continue to grow.

During a physical exam, a health care provider most often\n \n- examines a patients body, which can include checking for - discharge from the urethra - enlarged or tender lymph nodes in the groin - a swollen or tender scrotum - taps on specific areas of the patients body - performs a digital rectal exam\n \nA digital rectal exam, or rectal exam, is a physical exam of the prostate. To perform the exam, the health care provider asks the man to bend over a table or lie on his side while holding his knees close to his chest. The health care provider slides a gloved, lubricated finger into the rectum and feels the part of the prostate that lies next to the rectum. The man may feel slight, brief discomfort during the rectal exam. A health care provider most often performs a rectal exam during an office visit, and men do not require anesthesia. The exam helps the health care provider see if the prostate is enlarged or tender or has any abnormalities that require more testing.\n \nMany health care providers perform a rectal exam as part of a routine physical exam for men age 40 or older, whether or not they have urinary problems.\n \nMedical Tests\n \nA health care provider may refer men to a urologista doctor who specializes in urinary problems and the male reproductive systemthough the health care provider most often diagnoses benign prostatic hyperplasia on the basis of symptoms and a digital rectal exam. A urologist uses medical tests to help diagnose lower urinary tract problems related to benign prostatic hyperplasia and recommend treatment. Medical tests may include\n \n- urinalysis - a prostate-specific antigen (PSA) blood test - urodynamic tests - cystoscopy - transrectal ultrasound - biopsy\n \nUrinalysis. Urinalysis involves testing a urine sample. The patient collects a urine sample in a special container in a health care providers office or a commercial facility. A health care provider tests the sample during an office visit or sends it to a lab for analysis. For the test, a nurse or technician places a strip of chemically treated paper, called a dipstick, into the urine. Patches on the dipstick change color to indicate signs of infection in urine.\n \nPSA blood test. A health care provider may draw blood for a PSA test during an office visit or in a commercial facility and send the sample to a lab for analysis. Prostate cells create a protein called PSA. Men who have prostate cancer may have a higher amount of PSA in their blood. However, a high PSA level does not necessarily indicate prostate cancer. In fact, benign prostatic hyperplasia, prostate infections, inflammation, aging, and normal fluctuations often cause high PSA levels. Much remains unknown about how to interpret a PSA blood test, the tests ability to discriminate between cancer and prostate conditions such as benign prostatic hyperplasia, and the best course of action to take if the PSA level is high.\n \nUrodynamic tests. Urodynamic tests include a variety of procedures that look at how well the bladder and urethra store and release urine. A health care provider performs urodynamic tests during an office visit or in an outpatient center or a hospital. Some urodynamic tests do not require anesthesia; others may require local anesthesia. Most urodynamic tests focus on the bladders ability to hold urine and empty steadily and completely and may include the following:\n \n- uroflowmetry, which measures how rapidly the bladder releases urine - postvoid residual measurement, which evaluates how much urine remains in the bladder after urination - reduced urine flow or residual urine in the bladder, which often suggests urine blockage due to benign prostatic hyperplasia\n \nMore information is provided in the NIDDK health topic, Urodynamic Testing.\n \nCystoscopy. Cystoscopy is a procedure that uses a tubelike instrument, called a cystoscope, to look inside the urethra and bladder. A urologist inserts the cystoscope through the opening at the tip of the penis and into the lower urinary tract. A urologist performs cystoscopy during an office visit or in an outpatient center or a hospital. The urologist will give the patient local anesthesia; however, in some cases, the patient may require sedation and regional or general anesthesia. A urologist may use cystoscopy to look for blockage or stones in the urinary tract.\n \nMore information is provided in the NIDDK health topic, Cystoscopy and Ureteroscopy.\n \nTransrectal ultrasound. Transrectal ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. The health care provider can move the transducer to different angles to make it possible to examine different organs. A specially trained technician performs the procedure in a health care providers office, an outpatient center, or a hospital, and a radiologista doctor who specializes in medical imaginginterprets the images; the patient does not require anesthesia. Urologists most often use transrectal ultrasound to examine the prostate. In a transrectal ultrasound, the technician inserts a transducer slightly larger than a pen into the mans rectum, next to the prostate. The ultrasound image shows the size of the prostate and any abnormalities, such as tumors. Transrectal ultrasound cannot reliably diagnose prostate cancer.\n \nBiopsy. Biopsy is a procedure that involves taking a small piece of prostate tissue for examination with a microscope. A urologist performs the biopsy in an outpatient center or a hospital. The urologist will give the patient light sedation and local anesthetic; however, in some cases, the patient will require general anesthesia. The urologist uses imaging techniques such as ultrasound, a computerized tomography scan, or magnetic resonance imaging to guide the biopsy needle into the prostate.

In these cases, instead of treatment, a urologist may recommend regular checkups. If benign prostatic hyperplasia symptoms become bothersome or present a health risk, a urologist most often recommends treatment.\n \nLifestyle Changes\n \nA health care provider may recommend lifestyle changes for men whose symptoms are mild or slightly bothersome. Lifestyle changes can include\n \n- reducing intake of liquids, particularly before going out in public or before periods of sleep - avoiding or reducing intake of caffeinated beverages and alcohol - avoiding or monitoring the use of medications such as decongestants, antihistamines, antidepressants, and diuretics - training the bladder to hold more urine for longer periods - exercising pelvic floor muscles - preventing or treating constipation\n \nMedications\n \nA health care provider or urologist may prescribe medications that stop the growth of or shrink the prostate or reduce symptoms associated with benign prostatic hyperplasia:\n \n- alpha blockers - phosphodiesterase-5 inhibitors - 5-alpha reductase inhibitors - combination medications\n \nAlpha blockers. These medications relax the smooth muscles of the prostate and bladder neck to improve urine flow and reduce bladder blockage:\n \n- terazosin (Hytrin) - doxazosin (Cardura) - tamsulosin (Flomax) - alfuzosin (Uroxatral) - silodosin (Rapaflo)\n \nPhosphodiesterase-5 inhibitors. Urologists prescribe these medications mainly for erectile dysfunction. Tadalafil (Cialis) belongs to this class of medications and can reduce lower urinary tract symptoms by relaxing smooth muscles in the lower urinary tract. Researchers are working to determine the role of erectile dysfunction drugs in the long-term treatment of benign prostatic hyperplasia.\n \n5-alpha reductase inhibitors. These medications block the production of DHT, which accumulates in the prostate and may cause prostate growth:\n \n- finasteride (Proscar) - dutasteride (Avodart)\n \nThese medications can prevent progression of prostate growth or actually shrink the prostate in some men. Finasteride and dutasteride act more slowly than alpha blockers and are useful for only moderately enlarged prostates.\n \nCombination medications. Several studies, such as the Medical Therapy of Prostatic Symptoms (MTOPS) study, have shown that combining two classes of medications, instead of using just one, can more effectively improve symptoms, urinary flow, and quality of life. The combinations include\n \n- finasteride and doxazosin - dutasteride and tamsulosin (Jalyn), a combination of both medications that is available in a single tablet - alpha blockers and antimuscarinics\n \nA urologist may prescribe a combination of alpha blockers and antimuscarinics for patients with overactive bladder symptoms. Overactive bladder is a condition in which the bladder muscles contract uncontrollably and cause urinary frequency, urinary urgency, and urinary incontinence. Antimuscarinics are a class of medications that relax the bladder muscles.\n \nMinimally Invasive Procedures\n \nResearchers have developed a number of minimally invasive procedures that relieve benign prostatic hyperplasia symptoms when medications prove ineffective. These procedures include\n \n- transurethral needle ablation - transurethral microwave thermotherapy - high-intensity focused ultrasound - transurethral electrovaporization - water-induced thermotherapy - prostatic stent insertion\n \nMinimally invasive procedures can destroy enlarged prostate tissue or widen the urethra, which can help relieve blockage and urinary retention caused by benign prostatic hyperplasia.\n \nUrologists perform minimally invasive procedures using the transurethral method, which involves inserting a cathetera thin, flexible tubeor cystoscope through the urethra to reach the prostate. These procedures may require local, regional, or general anesthesia. Although destroying troublesome prostate tissue relieves many benign prostatic hyperplasia symptoms, tissue destruction does not cure benign prostatic hyperplasia. A urologist will decide which procedure to perform based on the mans symptoms and overall health.\n \nTransurethral needle ablation. This procedure uses heat generated by radiofrequency energy to destroy prostate tissue. A urologist inserts a cystoscope through the urethra to the prostate. A urologist then inserts small needles through the end of the cystoscope into the prostate. The needles send radiofrequency energy that heats and destroys selected portions of prostate tissue. Shields protect the urethra from heat damage.\n \nTransurethral microwave thermotherapy. This procedure uses microwaves to destroy prostate tissue. A urologist inserts a catheter through the urethra to the prostate, and a device called an antenna sends microwaves through the catheter to heat selected portions of the prostate. The temperature becomes high enough inside the prostate to destroy enlarged tissue. A cooling system protects the urinary tract from heat damage during the procedure.\n \nHigh-intensity focused ultrasound. For this procedure, a urologist inserts a special ultrasound probe into the rectum, near the prostate. Ultrasound waves from the probe heat and destroy enlarged prostate tissue.\n \nTransurethral electrovaporization. For this procedure, a urologist inserts a tubelike instrument called a resectoscope through the urethra to reach the prostate. An electrode attached to the resectoscope moves across the surface of the prostate and transmits an electric current that vaporizes prostate tissue. The vaporizing effect penetrates below the surface area being treated and seals blood vessels, which reduces the risk of bleeding.\n \nWater-induced thermotherapy. This procedure uses heated water to destroy prostate tissue. A urologist inserts a catheter into the urethra so that a treatment balloon rests in the middle of the prostate. Heated water flows through the catheter into the treatment balloon, which heats and destroys the surrounding prostate tissue. The treatment balloon can target a specific region of the prostate, while surrounding tissues in the urethra and bladder remain protected.\n \nProstatic stent insertion. This procedure involves a urologist inserting a small device called a prostatic stent through the urethra to the area narrowed by the enlarged prostate. Once in place, the stent expands like a spring, and it pushes back the prostate tissue, widening the urethra. Prostatic stents may be temporary or permanent. Urologists generally use prostatic stents in men who may not tolerate or be suitable for other procedures.\n \nSurgery\n \nFor long-term treatment of benign prostatic hyperplasia, a urologist may recommend removing enlarged prostate tissue or making cuts in the prostate to widen the urethra. Urologists recommend surgery when\n \n- medications and minimally invasive procedures are ineffective - symptoms are particularly bothersome or severe - complications arise\n \nAlthough removing troublesome prostate tissue relieves many benign prostatic hyperplasia symptoms, tissue removal does not cure benign prostatic hyperplasia.\n \nSurgery to remove enlarged prostate tissue includes\n \n- transurethral resection of the prostate (TURP) - laser surgery - open prostatectomy - transurethral incision of the prostate (TUIP)\n \nA urologist performs these surgeries, except for open prostatectomy, using the transurethral method. Men who have these surgical procedures require local, regional, or general anesthesia and may need to stay in the hospital.\n \nThe urologist may prescribe antibiotics before or soon after surgery to prevent infection. Some urologists prescribe antibiotics only when an infection occurs.\n \nImmediately after benign prostatic hyperplasia surgery, a urologist may insert a special catheter, called a Foley catheter, through the opening of the penis to drain urine from the bladder into a drainage pouch.\n \nTURP. With TURP, a urologist inserts a resectoscope through the urethra to reach the prostate and cuts pieces of enlarged prostate tissue with a wire loop. Special fluid carries the tissue pieces into the bladder, and the urologist flushes them out at the end of the procedure. TURP is the most common surgery for benign prostatic hyperplasia and considered the gold standard for treating blockage of the urethra due to benign prostatic hyperplasia.\n \nLaser surgery. With this surgery, a urologist uses a high-energy laser to destroy prostate tissue. The urologist uses a cystoscope to pass a laser fiber through the urethra into the prostate. The laser destroys the enlarged tissue. The risk of bleeding is lower than in TURP and TUIP because the laser seals blood vessels as it cuts through the prostate tissue. However, laser surgery may not effectively treat greatly enlarged prostates.\n \nOpen prostatectomy. In an open prostatectomy, a urologist makes an incision, or cut, through the skin to reach the prostate. The urologist can remove all or part of the prostate through the incision. This surgery is used most often when the prostate is greatly enlarged, complications occur, or the bladder is damaged and needs repair. Open prostatectomy requires general anesthesia, a longer hospital stay than other surgical procedures for benign prostatic hyperplasia, and a longer rehabilitation period. The three open prostatectomy procedures are retropubic prostatectomy, suprapubic prostatectomy, and perineal prostatectomy. The recovery period for open prostatectomy is different for each man who undergoes the procedure. However, it typically takes anywhere from 3 to 6 weeks.4\n \nTUIP. A TUIP is a surgical procedure to widen the urethra. During a TUIP, the urologist inserts a cystoscope and an instrument that uses an electric current or a laser beam through the urethra to reach the prostate. The urologist widens the urethra by making a few small cuts in the prostate and in the bladder neck. Some urologists believe that TUIP gives the same relief as TURP except with less risk of side effects.\n \nAfter surgery, the prostate, urethra, and surrounding tissues may be irritated and swollen, causing urinary retention. To prevent urinary retention, a urologist inserts a Foley catheter so urine can drain freely out of the bladder. A Foley catheter has a balloon on the end that the urologist inserts into the bladder. Once the balloon is inside the bladder, the urologist fills it with sterile water to keep the catheter in place. Men who undergo minimally invasive procedures may not need a Foley catheter.\n \nThe Foley catheter most often remains in place for several days. Sometimes, the Foley catheter causes recurring, painful, difficult-to-control bladder spasms the day after surgery. However, these spasms will eventually stop. A urologist may prescribe medications to relax bladder muscles and prevent bladder spasms. These medications include\n \n- oxybutynin chloride (Ditropan) - solifenacin (VESIcare) - darifenacin (Enablex) - tolterodine (Detrol) - hyoscyamine (Levsin) - propantheline bromide (Pro-Banthine)"} {"_id":"390be0db-76de-4a3e-9a28-4e2a07cda205","text":"The complications of benign prostatic hyperplasia treatment depend on the type of treatment.\n \nMedications\n \nMedications used to treat benign prostatic hyperplasia may have side effects that sometimes can be serious.

Use of a Foley catheter after benign prostatic hyperplasia surgery may increase the risk of a UTI. Anesthesia during surgery may cause urinary retention and also increase the risk of a UTI. In addition, the incision site of an open prostatectomy may become infected. A health care provider will prescribe antibiotics to treat infections.\n \nScar tissue. In the year after the original surgery, scar tissue sometimes forms and requires surgical treatment. Scar tissue may form in the urethra and cause it to narrow. A urologist can solve this problem during an office visit by stretching the urethra. Rarely, the opening of the bladder becomes scarred and shrinks, causing blockage. This problem may require a surgical procedure similar to TUIP.\n \nSexual dysfunction. Some men may experience temporary problems with sexual function after benign prostatic hyperplasia surgery. The length of time for restored sexual function depends on the type of benign prostatic hyperplasia surgery performed and how long symptoms were present before surgery. Many men have found that concerns about sexual function can interfere with sex as much as the benign prostatic hyperplasia surgery itself. Understanding the surgical procedure and talking about concerns with a health care provider before surgery often help men regain sexual function earlier. Many men find it helpful to talk with a counselor during the adjustment period after surgery. Even though it can take a while for sexual function to fully return, with time, most men can enjoy sex again.\n \nMost health care providers agree that if men with benign prostatic hyperplasia were able to maintain an erection before surgery, they will probably be able to have erections afterward. Surgery rarely causes a loss of erectile function. However, benign prostatic hyperplasia surgery most often cannot restore function that was lost before the procedure. Some men find a slight difference in the quality of orgasm after surgery. However, most report no difference.\n \nProstate surgery may make men sterile, or unable to father children, by causing retrograde ejaculationthe backward flow of semen into the bladder. Men flush the semen out of the bladder when they urinate. In some cases, medications such as pseudoephedrine, found in many cold medications, or imipramine can treat retrograde ejaculation. These medications improve muscle tone at the bladder neck and keep semen from entering the bladder.\n \nRecurring problems. Men may require further treatment if prostate problems, including benign prostatic hyperplasia, return. Problems may arise when treatments for benign prostatic hyperplasia leave a good part of the prostate intact. About 10 percent of men treated with TURP or TUIP require additional surgery within 5 years. About 2 percent of men who have an open prostatectomy require additional surgery within 5 years.2\n \nIn the years after benign prostatic hyperplasia surgery or treatment, men should continue having a digital rectal exam once a year and have any symptoms checked by a health care provider. In some cases, the health care provider may recommend a digital rectal exam and checkup more than once a year."} {"_id":"6d42aee6-ecff-4bd1-8e3b-30b23f83852c","text":"Researchers have not found a way to prevent benign prostatic hyperplasia.

When food enters the stomach after a meal, the gallbladder contracts, and the bile ducts carry bile to the duodenum, the first part of the small intestine, for use in digestion. The liver makes bile, which is made up of bile acids, cholesterol, fats, and fluids. Bile helps the body absorb fats, cholesterol, and fat-soluble vitamins. Bile also carries cholesterol, toxins, and waste products to the intestines, where the body removes them. When chronic inflammation, or swelling, damages the bile ducts, bile and toxic wastes build up in the liver, damaging liver tissue.\n \nThis damage to the liver tissue can lead to cirrhosis, a condition in which the liver slowly deteriorates and is unable to function normally. In cirrhosis, scar tissue replaces healthy liver tissue, partially blocking the flow of blood through the liver.\n \nThe liver is the bodys largest internal organ. The liver is called the bodys metabolic factory because of the important role it plays in metabolismthe way cells change food into energy after food is digested and absorbed into the blood. The liver has many functions, including\n \n- taking up, storing, and processing nutrients from foodincluding fat, sugar, and proteinand delivering them to the rest of the body when needed - making new proteins, such as clotting factors and immune factors - producing bile - removing waste products the kidneys cannot remove, such as fats, cholesterol, toxins, and medications\n \nA healthy liver is necessary for survival. The liver can regenerate most of its own cells when they become damaged. However, if injury to the liver is too severe or long lasting, regeneration is incomplete, and the liver creates scar tissue. Scarring of the liver may lead to cirrhosis.\n \nThe buildup of scar tissue that causes cirrhosis is usually a slow and gradual process. In the early stages of cirrhosis, the liver continues to function. However, as cirrhosis gets worse and scar tissue replaces more healthy tissue, the liver will begin to fail. Chronic liver failure, which is also called end-stage liver disease, progresses over months, years, or even decades. With end-stage liver disease, the liver can no longer perform important functions or effectively replace damaged cells.\n \nPrimary biliary cirrhosis usually occurs between the ages of 30 and 65 and affects women more often than men.1"} {"_id":"28c89bc0-bb57-40b4-a4ad-e4dc9c068a72","text":"The causes of primary biliary cirrhosis are unknown.

An autoimmune disease is a disorder in which the bodys immune system attacks the bodys own cells and organs. In primary biliary cirrhosis, the immune system attacks the small bile ducts in the liver.\n \nGenetics, or inherited genes, can make a person more likely to develop primary biliary cirrhosis.

In some cases, portal hypertension and esophageal varices may develop before cirrhosis.\n \nPortal hypertension. The portal vein carries blood from the stomach, intestines, spleen, gallbladder, and pancreas to the liver. In cirrhosis, scar tissue partially blocks the normal flow of blood, which increases the pressure in the portal vein. This condition is called portal hypertension. Portal hypertension is a common complication of cirrhosis. This condition may lead to other complications, such as\n \n- edemaswelling due to a buildup of fluidin the feet, ankles, or legs, and ascitesa buildup of fluid in the abdomen - enlarged blood vessels, called varices, in the esophagus, stomach, or both - an enlarged spleen, called splenomegaly - mental confusion due to a buildup of toxins that are ordinarily removed by the liver, a condition called hepatic encephalopathy\n \nEdema and ascites. Liver failure causes fluid buildup that results in edema and ascites. Ascites can lead to spontaneous bacterial peritonitis, a serious infection that requires immediate medical attention.\n \nVarices. Portal hypertension may cause enlarged blood vessels in the esophagus, stomach, or both. These enlarged blood vessels, called esophageal or gastric varices, cause the vessel walls to become thin and blood pressure to increase, making the blood vessels more likely to burst. If they burst, serious bleeding can occur in the esophagus or upper stomach, requiring immediate medical attention.\n \nSplenomegaly. Portal hypertension may cause the spleen to enlarge and retain white blood cells and platelets, reducing the numbers of these cells and platelets in the blood. A low platelet count may be the first evidence that a person has developed cirrhosis.\n \nHepatic encephalopathy. A failing liver cannot remove toxins from the blood, so they eventually accumulate in the brain. The buildup of toxins in the brain is called hepatic encephalopathy. This condition can decrease mental function and cause stupor and even coma. Stupor is an unconscious, sleeplike state from which a person can only be aroused briefly by a strong stimulus, such as a sharp pain. Coma is an unconscious, sleeplike state from which a person cannot be aroused. Signs of decreased mental function include\n \n- confusion - personality changes - memory loss - trouble concentrating - a change in sleep habits\n \nMetabolic bone diseases. Some people with cirrhosis develop a metabolic bone disease, which is a disorder of bone strength usually caused by abnormalities of vitamin D, bone mass, bone structure, or minerals, such as calcium and phosphorous. Osteopenia is a condition in which the bones become less dense, making them weaker. When bone loss becomes more severe, the condition is referred to as osteoporosis. People with these conditions are more likely to develop bone fractures.\n \nGallstones and bile duct stones. If cirrhosis prevents bile from flowing freely to and from the gallbladder, the bile hardens into gallstones. Symptoms of gallstones include abdominal pain and recurrent bacterial cholangitisirritated or infected bile ducts. Stones may also form in and block the bile ducts, causing pain, jaundice, and bacterial cholangitis.\n \nSteatorrhea. Steatorrhea is a condition in which the body cannot absorb fat, causing a buildup of fat in the stool and loose, greasy, and foul-smelling bowel movements. Steatorrhea may be caused by impairment of bile delivery to the small intestine or by the pancreas not producing enough digestive enzymes.\n \nLiver cancer. Liver cancer is common in people with cirrhosis. Liver cancer has a high mortality rate. Current treatments are limited and only fully successful if a health care provider detects the cancer early, before the tumor is too large. For this reason, health care providers should check people with cirrhosis for signs of liver cancer every 6 to 12 months. Health care providers use blood tests, ultrasound, or both to check for signs of liver cancer."} {"_id":"abf55d06-fdf6-4d0c-942d-fce67259d405","text":"A health care provider may use the following tests to diagnose primary biliary cirrhosis:\n \n- a medical and family history - a physical exam - blood tests - imaging tests - a liver biopsy\n \nA health care provider usually bases a diagnosis of primary biliary cirrhosis on two out of three of the following criteria:\n \n- a blood test showing elevated liver enzymes - a blood test showing the presence of anti-mitochondrial antibodies (AMA) - a liver biopsy showing signs of the disease\n \nHealth care providers may order additional tests to rule out other causes of symptoms. Health care providers diagnose the majority of people with primary biliary cirrhosis early in the course of the disease.\n \nMedical and family history. Taking a medical and family history is one of the first things a health care provider may do to help diagnose primary biliary cirrhosis. He or she will ask a patient to provide a medical and family history.\n \nPhysical exam. A physical exam may help diagnose primary biliary cirrhosis. During a physical exam, a health care provider usually\n \n- examines a patients body - uses a stethoscope to listen to sounds in the abdomen - taps on specific areas of the patients body\n \nThe health care provider will perform a physical exam to look for signs of the disease. For example, the liver may feel hard or ascites may cause the abdomen to enlarge.\n \nBlood test. A blood test involves drawing blood at a health care providers office or a commercial facility and sending the sample to a lab for analysis. The blood test can show elevated levels of liver enzymes, such as alkaline phosphatase. A routine blood test may show high levels of the liver enzyme alkaline phosphatase in people who have primary biliary cirrhosis and are not yet showing symptoms.\n \nThe health care provider will perform an AMA blood test to help confirm the diagnosis. A blood test will detect the presence of AMA in 90 to 95 percent of people with primary biliary cirrhosis.3\n \nImaging tests. A health care provider may use the following imaging tests to examine the bile ducts. These tests can distinguish between primary biliary cirrhosis and other conditions that affect the bile ducts.\n \n- Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. A specially trained technician performs the procedure in a health care providers office, an outpatient center, or a hospital, and a radiologista doctor who specializes in medical imaging interprets the images. A patient does not need anesthesia. In addition to showing problems with the bile ducts, the images can show signs of advanced cirrhosis or complications. - Magnetic resonance cholangiopancreatography uses magnetic resonance imaging (MRI) to examine the bile ducts. MRI machines use radio waves and magnets to produce detailed pictures of the bodys internal organs and soft tissues without using x rays. A specially trained technician performs magnetic resonance cholangiopancreatography in an outpatient center or a hospital, and a radiologist interprets the images. A patient does not need anesthesia, though a health care provider may use light sedation for patients with a fear of confined spaces. With most MRI machines, the patient lies on a table that slides into a tunnel-shaped device that may be open ended or closed at one end; some machines allow the patient to lie in a more open space. - Endoscopic retrograde cholangiopancreatography uses an x ray to look at the bile ducts. A gastroenterologista doctor who specializes in digestive diseasesperforms the test at a hospital or an outpatient center. After lightly sedating the patient, the gastroenterologist inserts an endoscopea small, flexible tube with a light and a camera on the endthrough the mouth into the duodenum and bile ducts. The endoscope is connected to a computer and video monitor. The gastroenterologist injects a special dye, called contrast medium, through the tube into the bile ducts, which makes the ducts show up on the monitor. This test is more invasive than other imaging tests, and health care providers do not routinely need the test to make the diagnosis of primary biliary cirrhosis. A health care provider uses the test selectively when he or she is concerned that the blockage of the bile ducts has another cause, such as a gallstone or a narrowing of the large bile ducts due to inflammation or cancer. Patients may have pain, nausea, or vomiting after the test or may develop bacterial cholangitis or pancreatitisinflammation of the pancreas.\n \nLiver biopsy. A liver biopsy is a procedure that involves taking a piece of liver tissue for examination with a microscope for signs of damage or disease. The health care provider may ask the patient to stop taking certain medications temporarily before the liver biopsy. The health care provider may ask the patient to fast for 8 hours before the procedure.\n \nDuring the procedure, the patient lies on a table, right hand resting above the head. The health care provider applies a local anesthetic to the area where he or she will insert the biopsy needle. If needed, a health care provider will also give sedatives and pain medication. The health care provider uses a needle to take a small piece of liver tissue. He or she may use ultrasound, computerized tomography scans, or other imaging techniques to guide the needle. After the biopsy, the patient must lie on the right side for up to 2 hours and is monitored an additional 2 to 4 hours before being sent home.\n \nA health care provider performs a liver biopsy at a hospital or an outpatient center. The health care provider sends the liver sample to a pathology lab, where the pathologista doctor who specializes in diagnosing diseaseslooks at the tissue with a microscope and sends a report to the patients health care provider.\n \nA liver biopsy can confirm the diagnosis of primary biliary cirrhosis; however, a person does not always need this test. A health care provider will perform a biopsy if the AMA blood test is negative and the person shows other signs of primary biliary cirrhosis. Sometimes a health care provider finds a cause of liver damage other than primary biliary cirrhosis during biopsy."} {"_id":"c4e74369-2071-4db7-9980-7d8c6482e4f7","text":"Treatment for primary biliary cirrhosis depends on how early a health care provider diagnoses the disease and whether complications are present. In the early stages of primary biliary cirrhosis, treatment can slow the progression of liver damage to cirrhosis. In the early stages of cirrhosis, the goals of treatment are to slow the progression of tissue scarring in the liver and prevent complications. As cirrhosis progresses, a person may need additional treatments and hospitalization to manage complications.\n \nMedications\n \nHealth care providers prescribe ursodiol (Actigall, Urso) to treat primary biliary cirrhosis. Ursodiol is a nontoxic bile acid that people can take orally. Ursodiol replaces the bile acids that are normally produced by the liver, which are more toxic and can harm the liver. Treatment with ursodiol can reduce levels of bilirubin and liver enzymes in the blood. Early treatment with this medication reduces the likelihood of needing a liver transplant and improves survival.3 Early treatment provides the most benefit; however, ursodiol treatment late in the course of the disease can still slow the progression of liver damage. While ursodiol treatment improves the outcome of primary biliary cirrhosis, it does not cure the disease.\n \nResearchers are studying the effects of several other medications on the progression of primary biliary cirrhosis. To date, none has shown the positive effects of ursodiol.\n \nAvoiding Alcohol and Other Substances\n \nPeople with cirrhosis should not drink any alcohol or take any illegal substances, as both will cause more liver damage. People with cirrhosis should avoid complementary and alternative medications, such as herbs. People with cirrhosis should be careful about starting new medications and should consult a health care provider before taking prescription medications, over-the-counter medications, or vitamins. Many vitamins and prescription and over-the-counter medications can affect liver function.\n \nTreatment of Symptoms and Complications\n \nHealth care providers treat symptoms and complications as follows:\n \nItching. Antihistamines may help with mild itching. However, antihistamines often cause drowsiness, and a person should take antihistamines just before bedtime to help with nighttime itching. A health care provider will treat more problematic itching with cholestyramine (Locholest, Questran), which reduces cholesterol in the blood. Experts believe high levels of cholesterol let substances that cause itching build up in tissues.\n \nDry eyes and mouth. Health care providers usually treat dry eyes and mouth with artificial tears and saliva substitutes, respectively. These products are available without a prescription. A health care provider may treat people whose symptoms do not improve with pilocarpine (Salagen) or cevimeline (Evoxac). People who have difficulty with dry eyes should see an ophthalmologista doctor who diagnoses and treats all eye diseases and eye disordersregularly. People with dry mouth should have regular dental exams.\n \nPortal hypertension. A health care provider may prescribe a beta-blocker or nitrate to treat portal hypertension. Beta-blockers lower blood pressure by helping the heart beat slower and with less force, and nitrates relax and widen blood vessels to let more blood flow to the heart and reduce the hearts workload.\n \nVarices. Beta-blockers can lower the pressure in varices and reduce the likelihood of bleeding. Bleeding in the stomach or esophagus requires an immediate upper endoscopy. This procedure involves using an endoscope to look for varices. The health care provider may use the endoscope to perform a band ligation, a procedure that involves placing a special rubber band around the varices that causes the tissue to die and fall off. A gastroenterologist performs the procedure at a hospital or an outpatient center. People who have had varices in the past may need to take medication to prevent future episodes.\n \nEdema and ascites. Health care providers prescribe diureticsmedications that remove fluid from the bodyto treat edema and ascites. A health care provider may remove large amounts of ascitic fluid from the abdomen and check for spontaneous bacterial peritonitis. A health care provider may prescribe bacteria-fighting medications called antibiotics to prevent infection. He or she may prescribe oral antibiotics; however, severe infection with ascites requires intravenous (IV) antibiotics.\n \nHepatic encephalopathy. A health care provider will treat hepatic encephalopathy by cleansing the bowel with lactulose, a laxative given orally or as an enemaa liquid put into the rectum. A health care provider may also add antibiotics to the treatment. Hepatic encephalopathy may improve as other complications of cirrhosis are controlled.\n \nOsteoporosis. A health care provider may prescribe bisphosphonate medications to improve bone density.\n \nGallstones and bile duct stones. A health care provider may use surgery to remove gallstones. He or she may use endoscopic retrograde cholangiopancreatography, which uses balloons and basketlike devices, to retrieve the bile duct stones.\n \nLiver cancer. A health care provider may recommend screening tests every 6 to 12 months to check for signs of liver cancer. Screening tests can find cancer before the person has symptoms of the disease. Cancer treatment is usually more effective when the health care provider finds the disease early. Health care providers use blood tests, ultrasound, or both to screen for liver cancer in people with cirrhosis. He or she may treat cancer with a combination of surgery, radiation, and chemotherapy."} {"_id":"e12f35d0-4cb6-4ae3-9709-7da81d470098","text":"A healthy diet is important in all stages of cirrhosis because malnutrition is common in people with this disease.

The two key markers for kidney disease are eGFR and urine albumin.\n \n- eGFR. eGFR stands for estimated glomerular filtration rate. Each kidney contains about 1 million tiny filters made up of blood vessels. These filters are called glomeruli. Kidney function can be checked by estimating how much blood the glomeruli filter in a minute. The calculation of eGFR is based on the amount of creatinine, a waste product, found in a blood sample. As the level of creatinine goes up, the eGFR goes down. Kidney disease is present when eGFR is less than 60 milliliters per minute. The American Diabetes Association (ADA) and the National Institutes of Health (NIH) recommend that eGFR be calculated from serum creatinine at least once a year in all people with diabetes. - Urine albumin.

A cystocele receives one of three grades depending on how far a womans bladder has dropped into her vagina:\n \n- grade 1mild, when the bladder drops only a short way into the vagina - grade 2moderate, when the bladder drops far enough to reach the opening of the vagina - grade 3most advanced, when the bladder bulges out through the opening of the vagina\n \nIf a woman has difficulty emptying her bladder, a health care provider may measure the amount of urine left in the womans bladder after she urinates. The remaining urine is called the postvoid residual. A health care provider can measure postvoid residual with a bladder ultrasound. A bladder ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off the bladder to create an image and show the amount of remaining urine.

Although not yet approved, rapid polymerase chain reaction diagnostic tests have been developed to detect T. whipplei DNA and may be useful in diagnosis.\n \nUpper Gastrointestinal Endoscopy and Enteroscopy\n \nAn upper GI endoscopy and enteroscopy are procedures that use an endoscopea small, flexible tube with a lightto see the upper GI tract. A health care provider performs these tests at a hospital or an outpatient center. The health care provider carefully feeds the endoscope down the esophagus and into the stomach and duodenum.\n \nOnce the endoscope is in the duodenum, the health care provider will use smaller tools and a smaller scope to see more of the small intestine. These additional procedures may include\n \n- push enteroscopy, which uses a long endoscope to examine the upper portion of the small intestine. - double-balloon enteroscopy, which uses balloons to help move the endoscope through the entire small intestine. - capsule enteroscopy, during which the patient swallows a capsule containing a tiny camera. As the capsule passes through the GI tract, the camera will transmit images to a video monitor. Using this procedure, the health care provider can examine the entire digestive tract.\n \nA small camera mounted on the endoscope transmits a video image to a monitor, allowing close examination of the intestinal lining. A health care provider may give a patient a liquid anesthetic to gargle or may spray anesthetic on the back of the patients throat. A health care provider will place an intravenous (IV) needle in a vein in the arm or hand to administer sedation. Sedatives help patients stay relaxed and comfortable. The test can show changes in the lining of the small intestine that can occur with Whipple disease.\n \nThe health care provider can use tiny tools passed through the endoscope to perform biopsies. A biopsy is a procedure that involves taking a piece of tissue for examination with a microscope. A pathologista doctor who specializes in examining tissues to diagnose diseasesexamines the tissue from the stomach lining in a lab. The pathologist applies a special stain to the tissue and examines it for T. whipplei-infected cells with a microscope. Once the pathologist completes the examination of the tissue, he or she sends a report to the gastroenterologist for review. More information is provided in the NIDDK health topic, Upper GI Endoscopy."} {"_id":"16e520b4-b1f4-4606-b8fe-45b1eee4aa5c","text":"The health care provider prescribes antibiotics to destroy the T. whipplei bacteria and treat Whipple disease.

Oral antibiotics may include\n \n- trimethoprim\/sulfamethoxazole (Septra, Bactrim)a combination antibiotic - doxycycline (Vibramycin)\n \nPatients should finish the prescribed course of antibiotics to ensure the medication destroyed all T. whipplei bacteria in the body. Patients who feel better may still have the bacteria in the small intestine or other areas of the body for 1 to 2 years.

A health care provider will prescribe additional or new antibiotics if a relapse occurs. Some people will relapse years after treatment, so it is important for patients to schedule routine follow-ups with the health care provider. Most patients have good outcomes with an early diagnosis and complete treatment.\n \nHealth care providers treat patients with neurologic symptoms at diagnosis or during relapse more aggressively.

Sphincter muscles surround the urethra and keep it closed to hold urine in the bladder. If the nerves to the sphincter muscles are damaged, the muscles may become loose and allow leakage or stay tight when you are trying to release urine.\n \nUrine retention. For some people, nerve damage means their bladder muscles do not get the message that it is time to release urine or are too weak to completely empty the bladder. If the bladder becomes too full, urine may back up and the increasing pressure may damage the kidneys. Or urine that stays too long may lead to an infection in the kidneys or bladder.

Your doctor may ask you to keep a bladder diary-a record of your fluid intake, trips to the bathroom, and episodes of urine leakage. This record may indicate a pattern and suggest ways to avoid accidents by making a point of using the bathroom at certain times of the day-a practice called timed voiding. As you gain control, you can extend the time between trips to the bathroom. Bladder training also includes Kegel exercises to strengthen the muscles that hold in urine.\n \nElectrical stimulation. Mild electrical pulses can be used to stimulate the nerves that control the bladder and sphincter muscles. Depending on which nerves the doctor plans to treat, these pulses can be given through the vagina or anus, or by using patches on the skin. Another method is a minor surgical procedure to place the electric wire near the tailbone. This procedure involves two steps. First, the wire is placed under the skin and connected to a temporary stimulator, which you carry with you for several days. If your condition improves during this trial period, then the wire is placed next to the tailbone and attached to a permanent stimulator under your skin. The Food and Drug Administration (FDA) has approved this device, marketed as the InterStim system, to treat urge incontinence, urgency-frequency syndrome, and urinary retention in patients for whom other treatments have not worked.\n \nDrug therapy. Different drugs can affect the nerves and muscles of the urinary tract in different ways.\n \n- Drugs that relax bladder muscles and prevent bladder spasms include oxybutynin chloride (Ditropan), tolterodine (Detrol), hyoscyamine (Levsin), and propantheline bromide (Pro-Banthine), which belong to the class of drugs called anticholinergics. Their most common side effect is dry mouth, although large doses may cause blurred vision, constipation, a faster heartbeat, and flushing. A new patch delivery system for oxybutynin (Oxytrol) may decrease side effects. Ditropan XL and Detrol LA are timed-release formulations that deliver a low level of the drug continuously in the body. These drugs have the advantage of once-a-day administration. In 2004, the FDA approved trospium chloride (Sanctura), darifenacin (Enablex), and solifenacin succinate (VESIcare) for the treatment of overactive bladder. - Drugs for depression that also relax bladder muscles include imipramine hydrochloride (Tofranil), a tricyclic antidepressant. Side effects may include fatigue, dry mouth, dizziness, blurred vision, nausea, and insomnia.\n \nAdditional drugs are being evaluated for the treatment of overactive bladder and may soon receive FDA approval.\n \nSurgery. In extreme cases, when incontinence is severe and other treatments have failed, surgery may be considered. The bladder may be made larger through an operation known as augmentation cystoplasty, in which a part of the diseased bladder is replaced with a section taken from the patient's bowel. This operation may improve the ability to store urine but may make the bladder more difficult to empty, making regular catheterization necessary. Additional risks of surgery include the bladder breaking open and leaking urine into the body, bladder stones, mucus in the bladder, and infection."} {"_id":"ca706102-4165-4856-9c10-d5e09b4a785b","text":"The job of the sphincter muscles is to hold urine in the bladder by squeezing the urethra shut. If the urethral sphincter fails to stay closed, urine may leak out of the bladder. When nerve signals are coordinated properly, the sphincter muscles relax to allow urine to pass through the urethra as the bladder contracts to push out urine. If the signals are not coordinated, the bladder and the sphincter may contract at the same time, so urine cannot pass easily.\n \nDrug therapy for an uncoordinated bladder and urethra. Scientists have not yet found a drug that works selectively on the urethral sphincter muscles, but drugs used to reduce muscle spasms or tremors are sometimes used to help the sphincter relax. Baclofen (Lioresal) is prescribed for muscle spasms or cramping in patients with multiple sclerosis and spinal injuries. Diazepam (Valium) can be taken as a muscle relaxant or to reduce anxiety. Drugs called alpha-adrenergic blockers can also be used to relax the sphincter. Examples of these drugs are alfuzosin (UroXatral), tamsulosin (Flomax), terazosin (Hytrin), and doxazosin (Cardura). The main side effects are low blood pressure, dizziness, fainting, and nasal congestion. All of these drugs have been used to relax the urethral sphincter in people whose sphincter does not relax well on its own.\n \nBotox injection. Botulinum toxin type A (Botox) is best known as a cosmetic treatment for facial wrinkles. Doctors have also found that botulinum toxin is useful in blocking spasms like eye ticks or relaxing muscles in patients with multiple sclerosis. Urologists have found that injecting botulinum toxin into the tissue surrounding the sphincter can help it to relax. Although the FDA has approved botulinum toxin only for facial cosmetic purposes, researchers are studying the safety and effectiveness of botulinum toxin injection into the sphincter for possible FDA approval in the future."} {"_id":"72b0ccbe-d21b-425f-896a-5f2c3dd0d21b","text":"Urine retention may occur either because the bladder wall muscles cannot contract or because the sphincter muscles cannot relax.\n \nCatheter. A catheter is a thin tube that can be inserted through the urethra into the bladder to allow urine to flow into a collection bag. If you are able to place the catheter yourself, you can learn to carry out the procedure at regular intervals, a practice called clean intermittent catheterization. Some patients cannot place their own catheters because nerve damage affects their hand coordination as well as their voiding function. These patients need to have a caregiver place the catheter for them at regular intervals. If regular catheter placement is not feasible, the patients may need to have an indwelling catheter that can be changed less often. Indwelling catheters have several risks, including infection, bladder stones, and bladder tumors. However, if the bladder cannot be emptied any other way, then the catheter is the only way to stop the buildup of urine in the bladder that can damage the kidneys.\n \nUrethral stent. Stents are small tube-like devices inserted into the urethra and allowed to expand, like a spring, widening the opening for urine to flow out. Stents can help prevent urine backup when the bladder wall and sphincter contract at the same time because of improper nerve signals. However, stents can cause problems if they move or lead to infection.\n \nSurgery. Men may consider a surgery that removes the external sphincter-a sphincterotomy-or a piece of it-a sphincter resection-to prevent urinary retention. The surgeon will pass a thin instrument through the urethra to deliver electrical or laser energy that burns away sphincter tissue. Possible complications include bleeding that requires a transfusion and, rarely, problems with erections. This procedure causes loss of urine control and requires the patient to collect urine by wearing an external catheter that fits over the penis like a condom. No external collection device is available for women.\n \nUrinary diversion. If other treatments fail and urine regularly backs up and damages the kidneys, the doctor may recommend a urinary diversion, a procedure that may require an outside collection bag attached to a stoma, a surgically created opening where urine passes out of the body. Another form of urinary diversion replaces the bladder with a continent urinary reservoir, an internal pouch made from sections of the bowel or other tissue. This method allows the person to store urine inside the body until a catheter is used to empty it through a stoma."} {"_id":"07b458c5-10c5-4a5a-b6cd-2d8435b56423","text":"For people who are on dialysis or approaching total kidney failure, adequate nutrition is important for maintaining energy, strength, healthy sleep patterns, bone health, heart health, and good mental health.

Once the cooper is in the bloodstream, the kidneys then filter the copper and pass it into the urine. A health care provider usually recommends chelating agents at the beginning of treatment. A potential side effect of chelating agents is that nervous system symptoms may become worse during treatment. The two medications available for this type of treatment include\n \n- trientine (Syprine)the risk for side effects and worsening nervous system symptoms appears to be lower with trientine than d-penicillamine. Researchers are still studying the side effects; however, some health care providers prefer to prescribe trientine as the first treatment of choice because it appears to be safer. - d-penicillaminepeople taking d-penicillamine may have other reactions or side effects, such as - fever - a rash - kidney problems - bone marrow problems\n \nA health care provider will prescribe a lower dose of a chelating agent to women who are pregnant to reduce the risk of birth defects. A health care provider should consider future screening on any newborn whose parent has Wilson disease.\n \nZinc. A health care provider will prescribe zinc for patients who do not have symptoms, or after a person has completed successful treatment using a chelating agent and symptoms begin to improve. Zinc, taken by mouth as zinc salts such as zinc acetate (Galzin), blocks the digestive tracts absorption of copper from food. Although most people taking zinc usually do not experience side effects, some people may experience stomach upset. A health care provider may prescribe zinc for children with Wilson disease who show no symptoms. Women may take the full dosage of zinc safely during pregnancy.\n \nMaintenance, or long term, treatment begins when symptoms improve and tests show that copper is at a safe level. Maintenance treatment typically includes taking zinc or a lower dose of a chelating agent. A health care provider closely monitors the person and reviews regular blood and urine tests to ensure maintenance treatment controls the copper level in the body.\n \nTreatment for people with Wilson disease who have no symptoms may include a chelating agent or zinc in order to prevent symptoms from developing and stop or slow disease progression.\n \nPeople with Wilson disease will take medications for the rest of their lives. Follow-up and adherence to the health care providers treatment plan is necessary to manage symptoms and prevent organ damage."} {"_id":"dd5bffec-4839-48e6-ac37-84a850527b38","text":"People with Wilson disease should reduce their dietary copper intake by avoiding foods that are high in copper, such as\n \n- shellfish - liver - mushrooms - nuts - chocolate\n \nPeople should not eat these foods during the initial treatment and talk with the health care provider to discuss if they are safe to eat in moderation during maintenance treatment.\n \nPeople with Wilson disease whose tap water runs through copper pipes or comes from a well should check the copper levels in the tap water.

In addition, the body cannot respond normally to erythropoietin (EPO), a hormone made by the kidneys that stimulates bone marrow to produce red blood cells. Over time, this abnormal functioning causes a lower than normal number of red blood cells in the body.\n \nSome of the chronic diseases that lead to AI\/ACD include infectious and inflammatory diseases, kidney disease, and cancer. Certain treatments for chronic diseases may also impair red blood cell production and contribute to AI\/ACD.\n \nInfectious and inflammatory diseases. As part of the immune system response that occurs with infectious and inflammatory diseases, cells of the immune system release proteins called cytokines. Cytokines help heal the body and defend it against infection. However, they can also affect normal body functions.

People with kidney disease can develop anemia for several different reasons. Diseased kidneys often fail to make enough EPO. In addition, kidney disease results in abnormal absorption and use of iron, which is typical of AI\/ACD. Anemia worsens as kidney disease advances. Therefore, most people with kidney failure have anemia. Kidney failure is described as end-stage kidney disease, sometimes called ESRD, when treated with a kidney transplant or blood-filtering treatments called dialysis.\n \nPeople with kidney failure can also develop iron deficiency due to blood loss during hemodialysis, a type of dialysis that uses a special filter called a dialyzer to remove wastes from the blood.

AI\/ACD can occur with certain types of cancer, including Hodgkins disease, non-Hodgkins lymphoma, and breast cancer.

The urinary tract includes two kidneys, two ureters, a bladder, and a urethra. The kidneys are two bean-shaped organs, each about the size of a fist. They are located just below the rib cage, one on each side of the spine. Every day, the kidneys filter about 120 to 150 quarts of blood to produce about 1 to 2 quarts of urine, composed of wastes and extra fluid. Children produce less urine than adults. The amount produced depends on their age. The urine flows from the kidneys to the bladder through tubes called ureters. The bladder stores urine until releasing it through urination. When the bladder empties, urine flows out of the body through a tube called the urethra at the bottom of the bladder.\n \nThe kidneys and urinary system keep fluids and natural chemicals in the body balanced. While a baby is developing in the mothers womb, called prenatal development, the placentaa temporary organ joining mother and babycontrols much of that balance. The babys kidneys begin to produce urine at about 10 to 12 weeks after conception. However, the mothers placenta continues to do most of the work until the last few weeks of the pregnancy.

Severe reflux may prevent a kidney from developing normally and may increase the risk for damage from infections after birth. VUR usually affects only one ureter and kidney, though it can affect both ureters and kidneys. - Ureteropelvic junction (UPJ) obstruction. If urine is blocked where the ureter joins the kidney, only the kidney swells. The ureter remains a normal size. UPJ obstruction usually occurs in only one kidney.\n \n- Bladder outlet obstruction (BOO). BOO describes any blockage in the urethra or at the opening of the bladder.Posterior urethral valves (PUV), the most common form of BOO seen in newborns and during prenatal ultrasound exams, is a birth defect in boys in which an abnormal fold of tissue in the urethra keeps urine from flowing freely out of the bladder. This defect may cause swelling in the entire urinary tract, including the urethra, bladder, ureters, and kidneys. - Ureterocele. If the end of the ureter does not develop normally, it can bulge, creating a ureterocele. The ureterocele may obstruct part of the ureter or the bladder.\n \nSome babies are born with genetic conditions that affect several different systems in the body, including the urinary tract:\n \n- Prune belly syndrome (PBS). PBS is a group of birth defects involving poor development of the abdominal muscles, enlargement of the ureters and bladder, and both testicles remaining inside the body instead of descending into the scrotum. The skin over the abdomen is wrinkled, giving the appearance of a prune. PBS usually occurs in boys, and most children with PBS have hydronephrosisswelling in the kidneyand VUR. - Esophageal atresia (EA). EA is a birth defect in which the esophagusthe muscular tube that carries food and liquids from the mouth to the stomachlacks the opening for food to pass into the stomach. Babies born with EA may also have problems with their spinal columns, digestive systems, hearts, and urinary tracts. - Congenital heart defects. Heart defects range from mild to life threatening. Children born with heart defects also have a higher rate of problems in the urinary tract than children in the general population, suggesting that some types of heart and urinary defects may have a common genetic cause.\n \nUrine blockage can also be caused by spina bifida and other birth defects that affect the spinal cord.

Amniocentesis is a procedure in which amniotic fluid is removed from the mothers womb for testing. The procedure can be performed in the health care providers office, and local anesthetic may be used. The health care provider inserts a thin needle through the abdomen into the uterus to obtain a small amount of amniotic fluid. Cells from the fluid are grown in a lab and then analyzed. The health care provider usually uses ultrasound to find the exact location of the baby. The test can show whether the baby has certain birth defects and how well the babys lungs are developing. - Chorionic villus sampling (CVS). CVS is the removal of a small piece of tissue from the placenta for testing. The procedure can be performed in the health care providers office; anesthesia is not needed. The health care provider uses ultrasound to guide a thin tube or needle through the vagina or abdomen into the placenta. Cells are removed from the placenta and then analyzed. The test can show whether the baby has certain genetic defects.\n \nMost healthy women do not need all of these tests. Ultrasound exams during pregnancy are routine. Amniocentesis and CVS are recommended only when a risk of genetic problems exists because of family history or a problem is detected during an ultrasound.

Ultrasound can be used to view the childs urinary tract. For infants, the image is clearer than could be achieved while the baby was in the womb. - Voiding cystourethrogram (VCUG). VCUG is an x-ray image of the bladder and urethra taken while the bladder is full and during urination, also called voiding. The procedure is performed in an outpatient center or hospital by an x-ray technician supervised by a radiologist, who then interprets the images. While anesthesia is not needed, sedation may be used for some children. The bladder and urethra are filled with a special dye, called contrast medium, to make the structures clearly visible on the x-ray images. The x-ray machine captures images of the contrast medium while the bladder is full and when the child urinates. The test can show reflux or blockage of the bladder due to an obstruction, such as PUV. - Radionuclide scan. A radionuclide scan is an imaging technique that detects small amounts of radiation after a person is injected with radioactive chemicals. The dose of the radioactive chemicals is small; therefore, the risk of causing damage to cells is low. Radionuclide scans are performed in an outpatient center or hospital by a specially trained technician, and the images are interpreted by a radiologist. Anesthesia is not needed. Special cameras and computers are used to create images of the radioactive chemicals as they pass through the kidneys.

A shunt is a small tube that can be inserted into the babys bladder to release urine into the amniotic sac. The procedure is similar to amniocentesis, in that a needle is inserted through the mothers abdomen. Ultrasound guides placement of the shunt, which is attached to the end of the needle. Alternatively, an endoscopea small, flexible tube with a lightcan be used to place a shunt or to repair the problem causing the blockage.

However, not everyone experiences these symptoms.\n \nBurping. Burping, or belching, once in a while, especially during and after meals, is normal. However, people who burp frequently may be swallowing too much air and releasing it before the air enters the stomach.\n \nSome people who burp frequently may have an upper GI disorder, such as gastroesophageal reflux diseasea chronic condition in which stomach contents flow back up into the esophagus. People may believe that swallowing air and releasing it will relieve the discomfort, and they may intentionally or unintentionally develop a habit of burping to relieve discomfort.\n \nPassing gas. Passing gas around 13 to 21 times a day is normal.2 Flatulence is excessive gas in the stomach or intestine that can cause bloating and flatus. Flatulence may be the result of problems digesting certain carbohydrates.\n \nBloating. Bloating is a feeling of fullness and swelling in the abdomen, the area between the chest and hips. Problems digesting carbohydrates may cause increased gas and bloating. However, bloating is not always caused by too much gas. Bloating may result from diseases that affect how gas moves through the intestines, such as rapid gastric emptying, or from diseases that cause intestinal obstruction, such as colon cancer. People who have had many operations, internal hernias, or bands of internal scar tissue called adhesions may experience bloating.\n \nDisorders such as irritable bowel syndrome (IBS) can affect how gas moves through the intestines or increase pain sensitivity in the intestines. IBS is a functional GI disorder, meaning that the symptoms are caused by changes in how the digestive tract works. The most common symptoms of IBS are abdominal pain or discomfort, often reported as cramping, along with diarrhea, constipation, or both. IBS may give a sensation of bloating because of increased sensitivity to normal amounts of gas.\n \nEating a lot of fatty food can delay stomach emptying and cause bloating and discomfort, but not necessarily too much gas.\n \nAbdominal pain and discomfort. People may feel abdominal pain or discomfort when gas does not move through the intestines normally. People with IBS may be more sensitive to gas and feel pain when gas is present in the intestines."} {"_id":"6f946ddd-0847-4841-b725-980255682bc5","text":"People can try to find the cause of gas on their own by keeping a diary of what they eat and drink and how often they burp, pass gas, or have other symptoms.

Health care providers can provide advice about reducing gas and prescribe medications that may help.\n \nReducing swallowed air. Swallowing less air may help reduce gas, especially for people who burp frequently. A health care provider may suggest eating more slowly, avoiding gum and hard candies, or checking with a dentist to make sure dentures fit correctly.\n \nMaking dietary changes. People may be able to reduce gas by eating less of the foods that cause gas. However, many healthy foods may cause gas, such as fruits and vegetables, whole grains, and milk products. The amount of gas caused by certain foods varies from person to person. Effective dietary changes depend on learning through trial and error which foods cause a person to have gas and how much of the offending foods one can handle.\n \nWhile fat does not cause gas, limiting high-fat foods can help reduce bloating and discomfort. Less fat in the diet helps the stomach empty faster, allowing gases to move more quickly into the small intestine.\n \nTaking over-the-counter medications. Some over-the-counter medications can help reduce gas or the symptoms associated with gas:\n \n- Alpha-galactosidase (Beano), an over-the-counter digestive aid, contains the sugar-digesting enzyme that the body lacks to digest the sugar in beans and many vegetables. The enzyme comes in liquid and tablet form. Five drops are added per serving or one tablet is swallowed just before eating to break down the gas-producing sugars. Beano has no effect on gas caused by lactose or fiber. - Simethicone (Gas-X, Mylanta Gas) can relieve bloating and abdominal pain or discomfort caused by gas. - Lactase tablets or drops can help people with lactose intolerance digest milk and milk products to reduce gas. Lactase tablets are taken just before eating foods that contain lactose; lactase drops can be added to liquid milk products. Lactose-free and lactose-reduced milk and milk products are available at most grocery stores.\n \nTaking prescription medications.

The goal of treatment is to reduce inflammation, control symptoms, and eliminate infection, if it is present. Only a doctor can determine the cause of proctitis and the best course of treatment. With proper medical attention, proctitis can be successfully treated.\n \nProctitis from Infection\n \nIf lab tests confirm that an STD or non-STD infection is present, medication is prescribed based on the type of infection found. Antibiotics are prescribed to kill bacteria; antiviral medications are prescribed to treat viruses. Although some STD viruses cannot be eliminated, antivirals can control their symptoms.\n \nProctitis from Other Causes\n \nIf antibiotic use triggered proctitis, the doctor may prescribe a different antibiotic designed to destroy the harmful bacteria that have developed in the intestines.\n \nIf proctitis is caused by anorectal trauma, the activity causing the inflammation should be stopped. Healing usually occurs in 4 to 6 weeks. The doctor may recommend over-the-counter medications such as antidiarrheals and those used for pain relief, such as aspirin and ibuprofen.\n \nTreatment of radiation proctitis is based on symptoms. Radiation proctitis causing only mild symptoms such as occasional bleeding or tenesmus may heal without treatment. For people with persistent or severe bleeding, thermal therapy may be used to stop bleeding and inflammation. Thermal therapy is done during flexible sigmoidoscopy or colonoscopy and targets the rectal lining with a heat probe, electric current, or laser. Argon plasma coagulation is the most common thermal therapy used to control bleeding in radiation proctitis. In many cases, several treatments are required. Obstruction that results from a stricturea narrowing of the rectumcaused by radiation proctitis may be treated with stool softeners in mild cases. In people with narrower strictures, dilation to enlarge the narrow area may be required. Sucralfate, 5-aminosalicylic acidknown as 5-ASAor corticosteroid enemas can also be used to ease pain and reduce inflammation from radiation proctitis, although their effectiveness is limited.\n \nWhen a chronic IBD such as ulcerative colitis or Crohns disease causes proctitis, treatment aims to reduce inflammation, control symptoms, and induce and maintain remissiona period when the person is symptom-free.

Mild proctitis can often be effectively treated with topical mesalamine, either suppositories or enemas.\n \nSome people with IBD and proctitis cannot tolerateor may have an incomplete response torectal therapy with 5-ASA suppositories or enemas. For these people, the doctor may prescribe oral medications alone or in combination with rectal therapy. Oral medications commonly used for proctitis contain salicylate. These include sulfasalazine- or mesalamine-containing medications, such as Asacol, Dipentum, or Pentasa. Possible side effects of oral administration of sulfasalazine- or mesalaminecontaining medications include nausea, vomiting, heartburn, diarrhea, and headache. Improvement in symptoms, including a decrease in bleeding, can occur within a few days, although complete healing requires 4 to 6 weeks of therapy.\n \nCortisone or steroids. These medications, also called corticosteroids, are effective at reducing inflammation. Prednisone and budesonide are generic names of two medications in this group. Corticosteroids for proctitis may be taken in pill, suppository, or enema form. When symptoms are at their worst, corticosteroids are usually prescribed in a large dose. The dosage is then gradually lowered once symptoms are controlled. Corticosteroids can cause serious side effects, including greater susceptibility to infection and osteoporosis, or weakening of the bones.\n \nImmune system suppressors. Medications that suppress the immune systemcalled immunosuppressive medicationsare also used to treat proctitis. The most commonly prescribed medication is 6-mercaptopurine or a related medication, azathioprine. Immunosuppressive medications work by blocking the immune reaction that contributes to inflammation. These medications may cause side effects such as nausea, vomiting, and diarrhea and may lower a persons resistance to infection. Some patients are treated with a combination of corticosteroids and immunosuppressive medications. Some studies suggest that immunosuppressive medications may enhance the effectiveness of corticosteroids.\n \nInfliximab (Remicade). Researchers have found that high levels of a protein produced by the immune system, called tumor necrosis factor (TNF), are present in people with Crohns disease. Infliximab is the first of a group of medications that bind to TNF substances to block the bodys inflammation response. The U.S. Food and Drug Administration approved the medication for the treatment of moderate to severe Crohns disease that does not respond to standard therapiesmesalamine substances, corticosteroids, immunosuppressive medicationsand for the treatment of open, draining fistulas. The medication is also given to people who have Crohns disease with proctitis. Some studies suggest that infliximab may enhance the effectiveness of immunosuppressive medications.\n \nBacterial infection can occur with flare-ups of ulcerative colitis or Crohns disease.

Tests may also identify a nutritional disorder or underlying disease. To rule out any blockage or other structural problems, the health care provider may perform one or more of the following tests:\n \n- Upper gastrointestinal (GI) endoscopy. This procedure involves using an endoscopea small, flexible tube with a lightto see the upper GI tract, which includes the esophagus, stomach, and duodenumthe first part of the small intestine. The test is performed at a hospital or outpatient center by a gastroenterologista doctor who specializes in digestive diseases. The endoscope is carefully fed down the esophagus and into the stomach and duodenum. A small camera mounted on the endoscope transmits a video image to a monitor, allowing close examination of the intestinal lining. A person may receive a liquid anesthetic that is gargled or sprayed on the back of the throat. An intravenous (IV) needle is placed in a vein in the arm if general anesthesia is given. The test may show blockage or large bezoarssolid collections of food, mucus, vegetable fiber, hair, or other material that cannot be digested in the stomachthat are sometimes softened, dissolved, or broken up during an upper GI endoscopy. - Upper GI series. An upper GI series may be done to look at the small intestine. The test is performed at a hospital or outpatient center by an x-ray technician, and the images are interpreted by a radiologista doctor who specializes in medical imaging. Anesthesia is not needed. No eating or drinking is allowed for 8 hours before the procedure, if possible. If the person has diabetes, a health care provider may give different instructions about fasting before the test. During the procedure, the person will stand or sit in front of an x-ray machine and drink barium, a chalky liquid. Barium coats the small intestine, making signs of gastroparesis show up more clearly on x rays. Gastroparesis is likely if the x ray shows food in the stomach after fasting. A person may experience bloating and nausea for a short time after the test. For several days afterward, barium liquid in the GI tract causes stools to be white or light colored. A health care provider will give the person specific instructions about eating and drinking after the test. - Ultrasound. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. The procedure is performed in a health care providers office, outpatient center, or hospital by a specially trained technician, and the images are interpreted by a radiologist; anesthesia is not needed. The images can show whether gallbladder disease and pancreatitis could be the cause of a persons digestive symptoms, rather than gastroparesis. - Gastric emptying scintigraphy. The test involves eating a bland mealsuch as eggs or an egg substitutethat contains a small amount of radioactive material. The test is performed in a radiology center or hospital by a specially trained technician and interpreted by a radiologist; anesthesia is not needed. An external camera scans the abdomen to show where the radioactive material is located. The radiologist is then able to measure the rate of gastric emptying at 1, 2, 3, and 4 hours after the meal. If more than 10 percent of the meal is still in the stomach at 4 hours, the diagnosis of gastroparesis is confirmed. - SmartPill. The SmartPill is a small electronic device in capsule form. The SmartPill test is available at specialized outpatient centers. The images are interpreted by a radiologist. The device is swallowed and moves through the entire digestive tract, sending information to a cell-phone-sized receiver worn around the persons waist or neck. The recorded information provides a detailed record of how quickly food travels through each part of the digestive tract. - Gastric emptying breath test. With this test, the person eats a special test meal that includes a natural material with a special type of carbon in it.

Treatment helps people manage the condition so they can be as comfortable and active as possible."} {"_id":"6420f6fc-e527-4b83-a32b-61064627ee97","text":"Changing eating habits can sometimes help control the severity of gastroparesis symptoms. A health care provider may suggest eating six small meals a day instead of three large ones. If less food enters the stomach each time a person eats, the stomach may not become overly full, allowing it to empty more easily. Chewing food well, drinking noncarbonated liquids with a meal, and walking or sitting for 2 hours after a mealinstead of lying downmay assist with gastric emptying.\n \nA health care provider may also recommend avoiding high-fat and fibrous foods. Fat naturally slows digestion and some raw vegetables and fruits are more difficult to digest than other foods. Some foods, such as oranges and broccoli, contain fibrous parts that do not digest well. People with gastroparesis should minimize their intake of large portions of these foods because the undigested parts may remain in the stomach too long. Sometimes, the undigested parts form bezoars.\n \nWhen a person has severe symptoms, a liquid or pured diet may be prescribed. As liquids tend to empty more quickly from the stomach, some people may find a pured diet helps improve symptoms. Pured fresh or cooked fruits and vegetables can be incorporated into shakes and soups. A health care provider may recommend a dietitian to help a person plan meals that minimize symptoms and ensure all nutritional needs are met.\n \nWhen the most extreme cases of gastroparesis lead to severe nausea, vomiting, and dehydration, urgent care may be required at a medical facility where IV fluids can be given.\n \n\n \nMedications\n \nSeveral prescription medications are available to treat gastroparesis. A combination of medications may be used to find the most effective treatment.\n \nMetoclopramide (Reglan). This medication stimulates stomach muscle contractions to help with gastric emptying. Metoclopramide also helps reduce nausea and vomiting. The medication is taken 20 to 30 minutes before meals and at bedtime. Possible side effects of metoclopramide include fatigue, sleepiness, and depression. Currently, this is the only medication approved by the FDA for treatment of gastroparesis. However, the FDA has placed a black box warning on this medication because of rare reports of it causing an irreversible neurologic side effect called tardive dyskinesiaa disorder that affects movement.\n \nErythromycin. This antibiotic, prescribed at low doses, may improve gastric emptying. Like metaclopramide, erythromycin works by increasing the contractions that move food through the stomach. Possible side effects of erythromycin include nausea, vomiting, and abdominal cramps.\n \nOther medications. Other medications may be used to treat symptoms and problems related to gastroparesis. For example, medications known as antiemetics are used to help control nausea and vomiting.\n \nBotulinum Toxin\n \nBotulinum toxin is a nerve blocking agent also known as Botox. After passing an endoscope into the stomach, a health care provider injects the Botox into the pylorus, the opening from the stomach into the duodenum. Botox is supposed to help keep the pylorus open for longer periods of time and improve symptoms of gastroparesis. Although some initial research trials showed modest improvement in gastroparesis symptoms and the rate of gastric emptying following the injections, other studies have failed to show the same degree of effectiveness of the Botox injections.1\n \nGastric Electrical Stimulation\n \nThis treatment alternative may be effective for some people whose nausea and vomiting do not improve with dietary changes or medications. A gastric neurostimulator is a surgically implanted battery-operated device that sends mild electrical pulses to the stomach muscles to help control nausea and vomiting. The procedure may be performed at a hospital or outpatient center by a gastroenterologist. General anesthesia may be required. The gastroenterologist makes several tiny incisions in the abdomen and inserts a laparoscopea thin tube with a tiny video camera attached. The camera sends a magnified image from inside the stomach to a video monitor, giving the gastroenterologist a close-up view of the tissues. Once implanted, the settings on the battery-operated device can be adjusted to determine the settings that best control symptoms.\n \nJejunostomy\n \nIf medications and dietary changes dont work, and the person is losing weight or requires frequent hospitalization for dehydration, a health care provider may recommend surgically placing a feeding tube through the abdominal wall directly into a part of the small intestine called the jejunum. The surgical procedure is known as a jejunostomy. The procedure is performed by a surgeon at a hospital or outpatient center. Anesthesia is needed. The feeding tube bypasses the stomach and delivers a special liquid food with nutrients directly into the jejunum. The jejunostomy is used only when gastroparesis is extremely severe.\n \nParenteral Nutrition\n \nWhen gastroparesis is so severe that dietary measures and other treatments are not helping, a health care provider may recommend parenteral nutritionan IV liquid food mixture supplied through a special tube in the chest. The procedure is performed by a surgeon at a hospital or outpatient center; anesthesia is needed. The surgeon inserts a thin, flexible tube called a catheter into a chest vein, with the catheter opening outside the skin. A bag containing liquid nutrients is attached to the catheter, and the nutrients are transported through the catheter into the chest vein and into the bloodstream. This approach is a less preferable alternative to a jejunostomy and is usually a temporary treatment to get through a difficult period of gastroparesis."} {"_id":"a8ce2cf4-3865-44c3-8447-5e58ea35dde1","text":"An elevated blood glucose level directly interferes with normal stomach emptying, so good blood glucose control in people with diabetes is important.

People with diabetes have high blood glucose, also called high blood sugar or hyperglycemia.\n \nDiabetes is a disorder of metabolismthe way the body uses digested food for energy. The digestive tract breaks down carbohydratessugars and starches found in many foodsinto glucose, a form of sugar that enters the bloodstream. With the help of the hormone insulin, cells throughout the body absorb glucose and use it for energy. Diabetes develops when the body doesnt make enough insulin or is not able to use insulin effectively, or both.\n \nInsulin is made in the pancreas, an organ located behind the stomach. The pancreas contains clusters of cells called islets. Beta cells within the islets make insulin and release it into the blood.\n \nIf beta cells dont produce enough insulin, or the body doesnt respond to the insulin that is present, glucose builds up in the blood instead of being absorbed by cells in the body, leading to prediabetes or diabetes. Prediabetes is a condition in which blood glucose levels or A1C levelswhich reflect average blood glucose levelsare higher than normal but not high enough to be diagnosed as diabetes. In diabetes, the bodys cells are starved of energy despite high blood glucose levels.\n \nOver time, high blood glucose damages nerves and blood vessels, leading to complications such as heart disease, stroke, kidney disease, blindness, dental disease, and amputations. Other complications of diabetes may include increased susceptibility to other diseases, loss of mobility with aging, depression, and pregnancy problems. No one is certain what starts the processes that cause diabetes, but scientists believe genes and environmental factors interact to cause diabetes in most cases.\n \nThe two main types of diabetes are type 1 diabetes and type 2 diabetes. A third type, gestational diabetes, develops only during pregnancy. Other types of diabetes are caused by defects in specific genes, diseases of the pancreas, certain drugs or chemicals, infections, and other conditions. Some people show signs of both type 1 and type 2 diabetes."} {"_id":"c4dac02d-4ce7-4210-b1d5-5e4ab21f0715","text":"Type 1 diabetes is caused by a lack of insulin due to the destruction of insulin-producing beta cells in the pancreas. In type 1 diabetesan autoimmune diseasethe bodys immune system attacks and destroys the beta cells. Normally, the immune system protects the body from infection by identifying and destroying bacteria, viruses, and other potentially harmful foreign substances. But in autoimmune diseases, the immune system attacks the bodys own cells. In type 1 diabetes, beta cell destruction may take place over several years, but symptoms of the disease usually develop over a short period of time.\n \nType 1 diabetes typically occurs in children and young adults, though it can appear at any age. In the past, type 1 diabetes was called juvenile diabetes or insulin-dependent diabetes mellitus.\n \nLatent autoimmune diabetes in adults (LADA) may be a slowly developing kind of type 1 diabetes. Diagnosis usually occurs after age 30. In LADA, as in type 1 diabetes, the bodys immune system destroys the beta cells. At the time of diagnosis, people with LADA may still produce their own insulin, but eventually most will need insulin shots or an insulin pump to control blood glucose levels.\n \nGenetic Susceptibility\n \nHeredity plays an important part in determining who is likely to develop type 1 diabetes. Genes are passed down from biological parent to child. Genes carry instructions for making proteins that are needed for the bodys cells to function. Many genes, as well as interactions among genes, are thought to influence susceptibility to and protection from type 1 diabetes. The key genes may vary in different population groups. Variations in genes that affect more than 1 percent of a population group are called gene variants.\n \nCertain gene variants that carry instructions for making proteins called human leukocyte antigens (HLAs) on white blood cells are linked to the risk of developing type 1 diabetes. The proteins produced by HLA genes help determine whether the immune system recognizes a cell as part of the body or as foreign material. Some combinations of HLA gene variants predict that a person will be at higher risk for type 1 diabetes, while other combinations are protective or have no effect on risk.\n \nWhile HLA genes are the major risk genes for type 1 diabetes, many additional risk genes or gene regions have been found. Not only can these genes help identify people at risk for type 1 diabetes, but they also provide important clues to help scientists better understand how the disease develops and identify potential targets for therapy and prevention.\n \nGenetic testing can show what types of HLA genes a person carries and can reveal other genes linked to diabetes. However, most genetic testing is done in a research setting and is not yet available to individuals. Scientists are studying how the results of genetic testing can be used to improve type 1 diabetes prevention or treatment.\n \nAutoimmune Destruction of Beta Cells\n \nIn type 1 diabetes, white blood cells called T cells attack and destroy beta cells. The process begins well before diabetes symptoms appear and continues after diagnosis. Often, type 1 diabetes is not diagnosed until most beta cells have already been destroyed. At this point, a person needs daily insulin treatment to survive. Finding ways to modify or stop this autoimmune process and preserve beta cell function is a major focus of current scientific research.\n \nRecent research suggests insulin itself may be a key trigger of the immune attack on beta cells. The immune systems of people who are susceptible to developing type 1 diabetes respond to insulin as if it were a foreign substance, or antigen. To combat antigens, the body makes proteins called antibodies. Antibodies to insulin and other proteins produced by beta cells are found in people with type 1 diabetes. Researchers test for these antibodies to help identify people at increased risk of developing the disease. Testing the types and levels of antibodies in the blood can help determine whether a person has type 1 diabetes, LADA, or another type of diabetes.\n \nEnvironmental Factors\n \nEnvironmental factors, such as foods, viruses, and toxins, may play a role in the development of type 1 diabetes, but the exact nature of their role has not been determined. Some theories suggest that environmental factors trigger the autoimmune destruction of beta cells in people with a genetic susceptibility to diabetes. Other theories suggest that environmental factors play an ongoing role in diabetes, even after diagnosis.\n \nViruses and infections. A virus cannot cause diabetes on its own, but people are sometimes diagnosed with type 1 diabetes during or after a viral infection, suggesting a link between the two. Also, the onset of type 1 diabetes occurs more frequently during the winter when viral infections are more common. Viruses possibly associated with type 1 diabetes include coxsackievirus B, cytomegalovirus, adenovirus, rubella, and mumps. Scientists have described several ways these viruses may damage or destroy beta cells or possibly trigger an autoimmune response in susceptible people. For example, anti-islet antibodies have been found in patients with congenital rubella syndrome, and cytomegalovirus has been associated with significant beta cell damage and acute pancreatitisinflammation of the pancreas. Scientists are trying to identify a virus that can cause type 1 diabetes so that a vaccine might be developed to prevent the disease.\n \nInfant feeding practices. Some studies have suggested that dietary factors may raise or lower the risk of developing type 1 diabetes. For example, breastfed infants and infants receiving vitamin D supplements may have a reduced risk of developing type 1 diabetes, while early exposure to cows milk and cereal proteins may increase risk. More research is needed to clarify how infant nutrition affects the risk for type 1 diabetes.\n \nRead more in the Centers for Disease Control and Preventions (CDCs) publication National Diabetes Statistics Report, 2014 at www.cdc.gov for information about research studies related to type 1 diabetes."} {"_id":"c3e4177c-022d-4d6a-b118-3b0249f99f61","text":"Type 2 diabetesthe most common form of diabetesis caused by a combination of factors, including insulin resistance, a condition in which the bodys muscle, fat, and liver cells do not use insulin effectively. Type 2 diabetes develops when the body can no longer produce enough insulin to compensate for the impaired ability to use insulin. Symptoms of type 2 diabetes may develop gradually and can be subtle; some people with type 2 diabetes remain undiagnosed for years.\n \nType 2 diabetes develops most often in middle-aged and older people who are also overweight or obese. The disease, once rare in youth, is becoming more common in overweight and obese children and adolescents. Scientists think genetic susceptibility and environmental factors are the most likely triggers of type 2 diabetes.\n \nGenetic Susceptibility\n \nGenes play a significant part in susceptibility to type 2 diabetes. Having certain genes or combinations of genes may increase or decrease a persons risk for developing the disease. The role of genes is suggested by the high rate of type 2 diabetes in families and identical twins and wide variations in diabetes prevalence by ethnicity. Type 2 diabetes occurs more frequently in African Americans, Alaska Natives, American Indians, Hispanics\/Latinos, and some Asian Americans, Native Hawaiians, and Pacific Islander Americans than it does in non-Hispanic whites.\n \nRecent studies have combined genetic data from large numbers of people, accelerating the pace of gene discovery. Though scientists have now identified many gene variants that increase susceptibility to type 2 diabetes, the majority have yet to be discovered. The known genes appear to affect insulin production rather than insulin resistance. Researchers are working to identify additional gene variants and to learn how they interact with one another and with environmental factors to cause diabetes.\n \nStudies have shown that variants of the TCF7L2 gene increase susceptibility to type 2 diabetes. For people who inherit two copies of the variants, the risk of developing type 2 diabetes is about 80 percent higher than for those who do not carry the gene variant.1 However, even in those with the variant, diet and physical activity leading to weight loss help delay diabetes, according to the Diabetes Prevention Program (DPP), a major clinical trial involving people at high risk.\n \nGenes can also increase the risk of diabetes by increasing a persons tendency to become overweight or obese. One theory, known as the thrifty gene hypothesis, suggests certain genes increase the efficiency of metabolism to extract energy from food and store the energy for later use. This survival trait was advantageous for populations whose food supplies were scarce or unpredictable and could help keep people alive during famine. In modern times, however, when high-calorie foods are plentiful, such a trait can promote obesity and type 2 diabetes.\n \nObesity and Physical Inactivity\n \nPhysical inactivity and obesity are strongly associated with the development of type 2 diabetes. People who are genetically susceptible to type 2 diabetes are more vulnerable when these risk factors are present.\n \nAn imbalance between caloric intake and physical activity can lead to obesity, which causes insulin resistance and is common in people with type 2 diabetes. Central obesity, in which a person has excess abdominal fat, is a major risk factor not only for insulin resistance and type 2 diabetes but also for heart and blood vessel disease, also called cardiovascular disease (CVD). This excess belly fat produces hormones and other substances that can cause harmful, chronic effects in the body such as damage to blood vessels.\n \nThe DPP and other studies show that millions of people can lower their risk for type 2 diabetes by making lifestyle changes and losing weight. The DPP proved that people with prediabetesat high risk of developing type 2 diabetescould sharply lower their risk by losing weight through regular physical activity and a diet low in fat and calories. In 2009, a follow-up study of DPP participantsthe Diabetes Prevention Program Outcomes Study (DPPOS)showed that the benefits of weight loss lasted for at least 10 years after the original study began.2\n \nRead more about the DPP, funded under National Institutes of Health (NIH) clinical trial number NCT00004992, and the DPPOS, funded under NIH clinical trial number NCT00038727 in Diabetes Prevention Program.\n \nInsulin Resistance\n \nInsulin resistance is a common condition in people who are overweight or obese, have excess abdominal fat, and are not physically active. Muscle, fat, and liver cells stop responding properly to insulin, forcing the pancreas to compensate by producing extra insulin. As long as beta cells are able to produce enough insulin, blood glucose levels stay in the normal range. But when insulin production falters because of beta cell dysfunction, glucose levels rise, leading to prediabetes or diabetes.\n \nAbnormal Glucose Production by the Liver\n \nIn some people with diabetes, an abnormal increase in glucose production by the liver also contributes to high blood glucose levels. Normally, the pancreas releases the hormone glucagon when blood glucose and insulin levels are low. Glucagon stimulates the liver to produce glucose and release it into the bloodstream. But when blood glucose and insulin levels are high after a meal, glucagon levels drop, and the liver stores excess glucose for later, when it is needed. For reasons not completely understood, in many people with diabetes, glucagon levels stay higher than needed. High glucagon levels cause the liver to produce unneeded glucose, which contributes to high blood glucose levels. Metformin, the most commonly used drug to treat type 2 diabetes, reduces glucose production by the liver.\n \nThe Roles of Insulin and Glucagon in Normal Blood Glucose Regulation\n \nA healthy persons body keeps blood glucose levels in a normal range through several complex mechanisms. Insulin and glucagon, two hormones made in the pancreas, help regulate blood glucose levels:\n \n- Insulin, made by beta cells, lowers elevated blood glucose levels. - Glucagon, made by alpha cells, raises low blood glucose levels.\n \n- Insulin helps muscle, fat, and liver cells absorb glucose from the bloodstream, lowering blood glucose levels. - Insulin stimulates the liver and muscle tissue to store excess glucose. The stored form of glucose is called glycogen. - Insulin also lowers blood glucose levels by reducing glucose production in the liver.\n \n- Glucagon signals the liver and muscle tissue to break down glycogen into glucose, which enters the bloodstream and raises blood glucose levels. - If the body needs more glucose, glucagon stimulates the liver to make glucose from amino acids.\n \nMetabolic Syndrome\n \nMetabolic syndrome, also called insulin resistance syndrome, refers to a group of conditions common in people with insulin resistance, including\n \n- higher than normal blood glucose levels - increased waist size due to excess abdominal fat - high blood pressure - abnormal levels of cholesterol and triglycerides in the blood\n \nCell Signaling and Regulation\n \nCells communicate through a complex network of molecular signaling pathways. For example, on cell surfaces, insulin receptor molecules capture, or bind, insulin molecules circulating in the bloodstream. This interaction between insulin and its receptor prompts the biochemical signals that enable the cells to absorb glucose from the blood and use it for energy.\n \nProblems in cell signaling systems can set off a chain reaction that leads to diabetes or other diseases. Many studies have focused on how insulin signals cells to communicate and regulate action. Researchers have identified proteins and pathways that transmit the insulin signal and have mapped interactions between insulin and body tissues, including the way insulin helps the liver control blood glucose levels. Researchers have also found that key signals also come from fat cells, which produce substances that cause inflammation and insulin resistance.\n \nThis work holds the key to combating insulin resistance and diabetes. As scientists learn more about cell signaling systems involved in glucose regulation, they will have more opportunities to develop effective treatments.\n \nBeta Cell Dysfunction\n \nScientists think beta cell dysfunction is a key contributor to type 2 diabetes. Beta cell impairment can cause inadequate or abnormal patterns of insulin release. Also, beta cells may be damaged by high blood glucose itself, a condition called glucose toxicity.\n \nScientists have not determined the causes of beta cell dysfunction in most cases. Single gene defects lead to specific forms of diabetes called maturity-onset diabetes of the young (MODY). The genes involved regulate insulin production in the beta cells. Although these forms of diabetes are rare, they provide clues as to how beta cell function may be affected by key regulatory factors. Other gene variants are involved in determining the number and function of beta cells. But these variants account for only a small percentage of type 2 diabetes cases. Malnutrition early in life is also being investigated as a cause of beta cell dysfunction. The metabolic environment of the developing fetus may also create a predisposition for diabetes later in life.\n \nRisk Factors for Type 2 Diabetes\n \nPeople who develop type 2 diabetes are more likely to have the following characteristics:\n \n- age 45 or older - overweight or obese - physically inactive - parent or sibling with diabetes - family background that is African American, Alaska Native, American Indian, Asian American, Hispanic\/Latino, or Pacific Islander American - history of giving birth to a baby weighing more than 9 pounds - history of gestational diabetes - high blood pressure140\/90 or aboveor being treated for high blood pressure - high-density lipoprotein (HDL), or good, cholesterol below 35 milligrams per deciliter (mg\/dL), or a triglyceride level above 250 mg\/dL - polycystic ovary syndrome, also called PCOS - prediabetesan A1C level of 5.7 to 6.4 percent; a fasting plasma glucose test result of 100125 mg\/dL, called impaired fasting glucose; or a 2-hour oral glucose tolerance test result of 140199, called impaired glucose tolerance - acanthosis nigricans, a condition associated with insulin resistance, characterized by a dark, velvety rash around the neck or armpits - history of CVD\n \nThe American Diabetes Association (ADA) recommends that testing to detect prediabetes and type 2 diabetes be considered in adults who are overweight or obese and have one or more additional risk factors for diabetes. In adults without these risk factors, testing should begin at age 45."} {"_id":"4f94f8a2-b2d6-4fc9-98e6-4e37666eb270","text":"Insulin Resistance and Beta Cell Dysfunction\n \nHormones produced by the placenta and other pregnancy-related factors contribute to insulin resistance, which occurs in all women during late pregnancy. Insulin resistance increases the amount of insulin needed to control blood glucose levels. If the pancreas cant produce enough insulin due to beta cell dysfunction, gestational diabetes occurs.\n \nAs with type 2 diabetes, excess weight is linked to gestational diabetes. Overweight or obese women are at particularly high risk for gestational diabetes because they start pregnancy with a higher need for insulin due to insulin resistance. Excessive weight gain during pregnancy may also increase risk.\n \nFamily History\n \nHaving a family history of diabetes is also a risk factor for gestational diabetes, suggesting that genes play a role in its development. Genetics may also explain why the disorder occurs more frequently in African Americans, American Indians, and Hispanics\/Latinos. Many gene variants or combinations of variants may increase a womans risk for developing gestational diabetes. Studies have found several gene variants associated with gestational diabetes, but these variants account for only a small fraction of women with gestational diabetes.\n \nFuture Risk of Type 2 Diabetes\n \nBecause a womans hormones usually return to normal levels soon after giving birth, gestational diabetes disappears in most women after delivery. However, women who have gestational diabetes are more likely to develop gestational diabetes with future pregnancies and develop type 2 diabetes.3 Women with gestational diabetes should be tested for persistent diabetes 6 to 12 weeks after delivery and at least every 3 years thereafter.\n \nAlso, exposure to high glucose levels during gestation increases a childs risk for becoming overweight or obese and for developing type 2 diabetes later on. The result may be a cycle of diabetes affecting multiple generations in a family. For both mother and child, maintaining a healthy body weight and being physically active may help prevent type 2 diabetes."} {"_id":"4fdb25d1-da9e-411c-b522-285904d1d9df","text":"Other types of diabetes have a variety of possible causes.\n \nGenetic Mutations Affecting Beta Cells, Insulin, and Insulin Action\n \nSome relatively uncommon forms of diabetes known as monogenic diabetes are caused by mutations, or changes, in a single gene.

Scientists believe genes and environmental factors interact to cause diabetes in most cases. - People with diabetes have high blood glucose, also called high blood sugar or hyperglycemia. Diabetes develops when the body doesnt make enough insulin or is not able to use insulin effectively, or both. - Insulin is a hormone made by beta cells in the pancreas. Insulin helps cells throughout the body absorb and use glucose for energy. If the body does not produce enough insulin or cannot use insulin effectively, glucose builds up in the blood instead of being absorbed by cells in the body, and the body is starved of energy. - Prediabetes is a condition in which blood glucose levels or A1C levels are higher than normal but not high enough to be diagnosed as diabetes. People with prediabetes can substantially reduce their risk of developing diabetes by losing weight and increasing physical activity. - The two main types of diabetes are type 1 diabetes and type 2 diabetes. Gestational diabetes is a third form of diabetes that develops only during pregnancy. - Type 1 diabetes is caused by a lack of insulin due to the destruction of insulin-producing beta cells.

When blood flows through a narrow artery, it sometimes makes a whooshing sound, called a bruit. The health care provider may place a stethoscope on the front or the side of the abdomen to listen for this sound. The absence of this sound, however, does not exclude the possibility of RAS.\n \nIn some cases, RAS is found when a person has a test for another reason. For example, a health care provider may find RAS during a coronary angiogram for diagnosis of heart problems. A coronary angiogram is a procedure that uses a special dye, called contrast medium, and x rays to see how blood flows through the heart.\n \nThe following imaging tests are used to diagnose RAS:\n \n- Duplex ultrasound. Duplex ultrasound combines traditional ultrasound with Doppler ultrasonography. Traditional ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. Doppler ultrasonography records sound waves reflected off of moving objects, such as blood, to measure their speed and other aspects of how they flow. The procedure is performed in a health care providers office, outpatient center, or hospital by a specially trained technician, and the images are interpreted by a radiologista doctor who specializes in medical imaging. Anesthesia is not needed. The images can show blockage in the renal artery or blood moving through nearby arteries at a lower-than-normal speed. Ultrasound is noninvasive and low cost. - Catheter angiogram. A catheter angiogram, also called a traditional angiogram, is a special kind of x ray in which a thin, flexible tube called a catheter is threaded through the large arteries, often from the groin, to the artery of interestin this case, the renal artery. The procedure is performed in a hospital or outpatient center by a radiologist. Anesthesia is not needed though a sedative may be given to lessen anxiety during the procedure. Contrast medium is injected through the catheter so the renal artery shows up more clearly on the x ray. Catheter angiogram is the gold standard for diagnosing RAS due to the high quality of the image produced. In addition, severe RAS can be treated during the same visit. However, a catheter angiogram is an invasive procedure, and a person may have side effects from the sedative or contrast medium or may have bleeding or injury to the artery from the catheter. The procedure is also more expensive than other imaging tests. - Computerized tomographic angiography (CTA) scan. CTA scans use a combination of x rays and computer technology to create images. The procedure is performed in an outpatient center or hospital by an x-ray technician, and the images are interpreted by a radiologist. Anesthesia is not needed. Contrast medium is injected into a vein in the persons arm to better see the structure of the arteries. CTA scans require the person to lie on a table that slides into a tunnel-shaped device where the x rays are taken. CTA scans are less invasive than catheter angiograms and take less time. However, the risks from the x-ray radiation still exist, and the test often requires more contrast medium than a catheter angiogram, so it may not be recommended for a person with poor kidney function. - Magnetic resonance angiogram (MRA). MRA uses radio waves and magnets to produce detailed pictures of the bodys internal organs and soft tissues without using x rays. The procedure is performed in an outpatient center or hospital by an x-ray technician, and the images are interpreted by a radiologist. Anesthesia is not needed though light sedation may be used for people with a fear of confined spaces. Contrast medium may be injected into a vein in the persons arm to better see the structure of the arteries. With most MRA scans, the person lies on a table that slides into a tunnel-shaped device that may be open ended or closed at one end; some newer machines are designed to allow the person to lie in a more open space. In addition to providing high-quality images noninvasively, MRA can provide a functional assessment of blood flow and organ function. However, the use of contrast medium for an MRA is not advised for people with poor kidney function because of the risk of complications to the skin and other organs if the kidneys do not remove the contrast medium well enough."} {"_id":"ae3bafa8-7cb2-4d81-8c48-12f419a98d01","text":"Treatment for RAS includes lifestyle changes, medications, and surgery and aims to\n \n- prevent RAS from getting worse - treat RVH - relieve the blockage of the renal arteries\n \nRAS that has not led to RVH or caused a significant blockage of the artery may not need treatment. RAS that needs to be treated, also called critical RAS, is defined by the American Heart Association as a reduction by more than 60 percent in the diameter of the renal artery.1 However, health care providers are not exactly sure what degree of blockage will cause significant problems.\n \nLifestyle Changes\n \nThe first step in treating RAS is making lifestyle changes that promote healthy blood vessels throughout the body, including the renal arteries. The best ways to keep plaque from building up in the arteries are to exercise, maintain a healthy body weight, and choose healthy foods. People who smoke should quit to help protect their kidneys and other internal organs.\n \nMedications\n \nPeople with RVH may need to take medications thatwhen taken as prescribed by their health care providerlower blood pressure and can also significantly slow the progression of kidney disease. Two types of blood pressure-lowering medications, angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs), have proven effective in slowing the progression of kidney disease. Many people require two or more medications to control their blood pressure. In addition to an ACE inhibitor or an ARB, a diuretica medication that helps the kidneys remove fluid from the bloodmay be prescribed. Beta blockers, calcium channel blockers, and other blood pressure medications may also be needed. Some people with RAS cannot take an ACE inhibitor or ARB due to the effects on the kidneys. People with RAS who are prescribed an ACE inhibitor or ARB should have their kidney function checked within a few weeks of starting the medication.\n \nA cholesterol-lowering medication to prevent plaque from building up in the arteries and a blood-thinner, such as aspirin, to help the blood flow more easily through the arteries may also be prescribed.\n \nSurgery\n \nAlthough surgery has been used in the past for treatment of RAS due to atherosclerosis, recent studies have not shown improved outcomes with surgery compared with medication. However, surgery may be recommended for people with RAS caused by FMD or RAS that does not improve with medication. Different types of surgery for RAS include the following. The procedures are performed in a hospital by a vascular surgeona doctor who specializes in repairing blood vessels. Anesthesia is needed.\n \n- Angioplasty and stenting. Angioplasty is a procedure in which a catheter is put into the renal artery, usually through the groin, just as in a catheter angiogram. In addition, for angioplasty, a tiny balloon at the end of the catheter can be inflated to flatten the plaque against the artery wall. A small mesh tube, called a stent, may then be positioned inside the artery to keep plaque flattened and the artery open. People with RAS caused by FMD may be successfully treated with angioplasty alone, while angioplasty with stenting has a better outcome for people with RAS caused by atherosclerosis. - Endarterectomy or bypass surgery. In an endarterectomy, the plaque is cleaned out of the artery, leaving the inside lining smooth and clear. To create a bypass, a vein or synthetic tube is used to connect the kidney to the aorta. This new path serves as an alternate route for blood to flow around the blocked artery into the kidney. These procedures are not performed as often as in the past due to a high risk of complications during and after the procedure."} {"_id":"046cad63-160a-46d9-899b-57274d69c86a","text":"Limiting intake of fats, cholesterol, sodium, and sugar can help prevent atherosclerosis, which can lead to RAS.

High-fat diets are high in cholesterol. Cholesterol is a type of fat found in your bodys cells, blood, and many foods. Your body needs some cholesterol to work the right way. For example, your body uses cholesterol to make certain essential hormones and maintain nerve function. However, your body makes all the cholesterol it needs. If you often eat foods that are high in cholesterol, or if high cholesterol runs in your family, extra cholesterol in your blood can build up over time in the walls of your blood vessels and arteries. High blood cholesterol can lead to heart disease and stroke, some of the biggest health problems for people with diabetes. - Avoid high-sodium foods. Sodium is a mineral found in salt and other foods. High levels of sodium may raise your blood pressure. Some high-sodium foods include canned food, frozen dinners, and hot dogs. The amount of sodium is listed on the food label, so you can see which foods have the highest levels. Try to limit your sodium to less than a teaspoon a day, or about 2,300 milligrams (mg) a day. If you have high blood pressure or are African American, middle-aged, or older, aim for no more than 1,500 mg of sodium per day. Ask your doctor or your dietitian about how much sodium you can have. - Ask your doctor about the amount of potassium you need. Potassium is a mineral that helps your heartbeat stay regular and muscles work right. Healthy kidneys keep the right amount of potassium in your body. However, if you have severe kidney damage, high levels of potassium may cause an abnormal heart rhythm or even make your heart stop, called cardiac arrest. Some high-potassium foods include apricots, bananas, oranges, and potatoes.\n \nMore information about healthy eating and kidney disease is provided in the NIDDK health topics: - Eat Right to Feel Right on Hemodialysis - Nutrition for Advanced Chronic Kidney Disease in Adults - Nutrition for Early Chronic Kidney Disease in Adults - What I need to know about Eating and Diabetes"} {"_id":"cf69250c-b5a5-4541-a03c-9d5aee794a87","text":"Kidney failure, also called end-stage kidney disease or ESRD, means your kidneys no longer work well enough to do their job.

Scientists believe one cause of Crohn's disease may be an autoimmune reactionwhen a person's immune system attacks healthy cells in the body by mistake. Normally, the immune system protects the body from infection by identifying and destroying bacteria, viruses, and other potentially harmful foreign substances. Researchers believe bacteria or viruses can mistakenly trigger the immune system to attack the inner lining of the intestines. This immune system response causes the inflammation, leading to symptoms.\n \nGenes. Crohn's disease sometimes runs in families. Research has shown that people who have a parent or sibling with Crohn's disease may be more likely to develop the disease. Researchers continue to study the link between genes and Crohn's disease.\n \nEnvironment. Some studies suggest that certain things in the environment may increase the chance of a person getting Crohn's disease, although the overall chance is low.

He or she will ask the patient to describe his or her\n \n- family history - symptoms - current and past medical conditions - current medications\n \nPhysical Exam\n \nA physical exam may help diagnose Crohn's disease. During a physical exam, the health care provider most often\n \n- checks for abdominal distension, or swelling - listens to sounds within the abdomen using a stethoscope - taps on the abdomen to check for tenderness and pain and establish if the liver or spleen is abnormal or enlarged\n \nLab Tests\n \nA health care provider may order lab tests, including blood and stool tests.\n \nBlood tests. A blood test involves drawing blood at a health care provider's office or a lab. A lab technologist will analyze the blood sample. A health care provider may use blood tests to look for changes in\n \n- red blood cells. When red blood cells are fewer or smaller than normal, a patient may have anemia. - white blood cells. When the white blood cell count is higher than normal, a person may have inflammation or infection somewhere in his or her body.\n \nStool tests. A stool test is the analysis of a sample of stool. A health care provider will give the patient a container for catching and storing the stool at home. The patient returns the sample to the health care provider or to a lab. A lab technologist will analyze the stool sample. Health care providers commonly order stool tests to rule out other causes of GI diseases.\n \nUpper Gastrointestinal Series\n \nAn upper GI series, also called a barium swallow, uses x-rays and fluoroscopy to help diagnose problems of the upper GI tract. Fluoroscopy is a form of x-ray that makes it possible to see the internal organs and their motion on a video monitor. An x-ray technician performs this test at a hospital or an outpatient center, and a radiologista doctor who specializes in medical imaginginterprets the images.\n \nThis test does not require anesthesia. A patient should not eat or drink before the procedure, as directed by the health care provider. Patients should ask their health care provider about how to prepare for an upper GI series.\n \nDuring the procedure, the patient will stand or sit in front of an x-ray machine and drink barium, a chalky liquid. Barium coats the esophagus, stomach, and small intestine so the radiologist and a health care provider can see the shape of these organs more clearly on x-rays.\n \nA patient may experience bloating and nausea for a short time after the test. For several days afterward, barium liquid in the GI tract causes white or light-colored stools. A health care provider will give the patient specific instructions about eating and drinking after the test.\n \nComputerized Tomography Scan\n \nComputerized tomography scans use a combination of x-rays and computer technology to create images. For a CT scan, a health care provider may give the patient a solution to drink and an injection of a special dye, called contrast medium. CT scans require the patient to lie on a table that slides into a tunnel-shaped device where the x-rays are taken. An x-ray technician performs the procedure in an outpatient center or a hospital, and a radiologist interprets the images. The patient does not need anesthesia. CT scans can diagnose both Crohn's disease and the complications seen with the disease.\n \nIntestinal Endoscopy\n \nIntestinal endoscopies are the most accurate methods for diagnosing Crohn's disease and ruling out other possible conditions, such as ulcerative colitis, diverticular disease, or cancer. Intestinal endoscopies include\n \n- upper GI endoscopy and enteroscopy - capsule endoscopy - colonoscopy\n \nUpper GI endoscopy and enteroscopy. An upper GI endoscopy is a procedure that uses an endoscopea small, flexible tube with a lightto directly visualize the lining of the upper GI tract. A health care provider performs the procedure at a hospital or an outpatient center. A nurse or technician may give the patient a liquid anesthetic to gargle or will spray the anesthetic on the back of a patient's throat. The anesthetic numbs the throat and calms the gag reflex. The nurse or technician will then place an intravenous (IV) needle in the person's arm or hand to provide a sedative. The health care provider carefully feeds the endoscope down the patient's esophagus and into the stomach. A small camera on the endoscope sends a video image to a monitor, allowing close examination of the GI tract.\n \nDuring an enteroscopy, the health care provider examines the small intestine with a special, longer endoscope. The health care provider carefully feeds the endoscope into the small intestine using one of the following procedures:\n \n- push enteroscopy, which uses a long endoscope to examine the upper portion of the small intestine - single- or double-balloon enteroscopy, which use small balloons to help move the endoscope into the small intestine - spiral enteroscopy, which uses a tube attached to an endocope that acts as a cork screw to move the instrument into the small intestine\n \nThe procedure most often takes between 15 and 60 minutes. The endoscope does not interfere with the patient's breathing, and many patients fall asleep during the procedure.\n \nCapsule endoscopy. Although this procedure can examine the entire digestive tract, health care providers use it mostly to examine the small intestine. The patient swallows a capsule containing a tiny camera. As the capsule passes through the GI tract, the camera will record and transmit images to a small receiver device worn by the patient. When the recording is done, the health care provider downloads the images and reviews them on a video monitor. The camera capsule leaves the patient's body during a bowel movement and is safely flushed down the toilet.\n \nColonoscopy. Colonoscopy is a test that uses a long, flexible, narrow tube with a light and tiny camera on one end, called a colonoscope or scope, to look inside a patient's rectum and entire colon. In most cases, light anesthesia and pain medication help patients relax for the test. The medical staff will monitor a patient's vital signs and try to make him or her as comfortable as possible. A nurse or technician will place an IV needle in a vein in the patient's arm or hand to give anesthesia.\n \nFor the test, the patient will lie on a table or stretcher while the gastroenterologist inserts a colonoscope into the patient's anus and slowly guides it through the rectum and into the colon. The scope inflates the large intestine with air to give the gastroenterologist a better view. The camera sends a video image of the intestinal lining to a monitor, allowing the gastroenterologist to examine the tissues lining the colon and rectum. The gastroenterologist may move the patient several times and adjust the scope for better viewing. Once the scope has reached the opening to the small intestine, the gastroenterologist slowly withdraws it and examines the lining of the colon and rectum again.\n \nA colonoscopy can show inflamed and swollen tissue, ulcers, and abnormal growths such as polypsextra pieces of tissue that grow on the inner lining of the intestine. If the gastroenterologist suspects Crohn's disease, he or she will biopsy the patient's colon and rectum. A biopsy is a procedure that involves taking small pieces of tissue for examination with a microscope.\n \nA health care provider will give patients written bowel prep instructions to follow at home before the test. The health care provider will also give patients information about how to care for themselves following the procedure."} {"_id":"2efc3cf2-2122-4912-bbed-d3ed0972385f","text":"A health care provider treats Crohn's disease with\n \n- medications - bowel rest - surgery\n \nWhich treatment a person needs depends on the severity of the disease and symptoms. Each person experiences Crohn's disease differently, so health care providers adjust treatments to improve the person's symptoms and induce, or bring about, remission.\n \nMedications\n \nWhile no medication cures Crohn's disease, many can reduce symptoms. The goals of medication therapy are\n \n- inducing and maintaining remission - improving the person's quality of life\n \nMany people with Crohn's disease require medication therapy. Health care providers will prescribe medications depending on the person's symptoms:\n \n- aminosalicylates - corticosteroids - immunomodulators - biologic therapies - other medications\n \nAminosalicylates are medications that contain 5-aminosalicyclic acid (5-ASA), which helps control inflammation. Health care providers use aminosalicylates to treat people newly diagnosed with Crohn's disease who have mild symptoms. Aminosalicylates include\n \n- balsalazide - mesalamine - olsalazine - sulfasalazinea combination of sulfapyridine and 5-ASA\n \nSome of the common side effects of aminosalicylates include\n \n- abdominal pain - diarrhea - headaches - heartburn - nausea and vomiting\n \nCorticosteroids, also known as steroids, help reduce the activity of the immune system and decrease inflammation. Health care providers prescribe corticosteroids for people with moderate to severe symptoms. Corticosteroids include\n \n- budesonide - hydrocortisone - methylprednisone - prednisone\n \nSide effects of corticosteroids include\n \n- acne - a higher chance of developing infections - bone mass loss - high blood glucose - high blood pressure - mood swings - weight gain\n \nIn most cases, health care providers do not prescribe corticosteroids for long-term use.\n \nImmunomodulators reduce immune system activity, resulting in less inflammation in the GI tract. These medications can take several weeks to 3 months to start working. Immunomodulators include\n \n- 6-mercaptopurine, or 6-MP - azathioprine - cyclosporine - methotrexate\n \nHealth care providers prescribe these medications to help people with Crohn's disease go into remission or to help people who do not respond to other treatments. People taking these medications may have the following side effects:\n \n- a low white blood cell count, which can lead to a higher chance of infection - fatigue, or feeling tired - nausea and vomiting - pancreatitis\n \nHealth care providers most often prescribe cyclosporine only to people with severe Crohn's disease because of the medication's serious side effects. People should talk with their health care provider about the risks and benefits of cyclosporine.\n \nBiologic therapies are medications that target a protein made by the immune system. Neutralizing this protein decreases inflammation in the intestine. Biologic therapies work quickly to bring on remission, especially in people who do not respond to other medications. Biologic therapies include\n \n- adalimumab - certolizumab - infliximab - natalizumab - vedolizumab\n \nHealth care providers most often give patients infliximab every 6 to 8 weeks at a hospital or an outpatient center. Side effects may include a toxic reaction to the medication and a higher chance of developing infections, particularly tuberculosis.\n \nOther medications to treat symptoms or complications may include\n \n- acetaminophen for mild pain. People with Crohn's disease should avoid using ibuprofen, naproxen, and aspirin since these medications can make symptoms worse. - antibiotics to prevent or treat infections and fistulas. - loperamide to help slow or stop severe diarrhea. In most cases, people only take this medication for short periods of time since it can increase the chance of developing megacolon.\n \nBowel Rest\n \nSometimes Crohn's disease symptoms are severe and a person may need to rest his or her bowel for a few days to several weeks. Bowel rest involves drinking only clear liquids or having no oral intake. To provide the patient with nutrition, a health care provider will deliver IV nutrition through a special catheter, or tube, inserted into a vein in the patient's arm. Some patients stay in the hospital, while other patients are able to receive the treatment at home. In most cases, the intestines are able to heal during bowel rest.\n \nSurgery\n \nEven with medication treatments, up to 20 percent of people will need surgery to treat their Crohn's disease.1 Although surgery will not cure Crohn's disease, it can treat complications and improve symptoms. Health care providers most often recommend surgery to treat\n \n- fistulas - bleeding that is life threatening - bowel obstructions - side effects from medications when they threaten a person's health - symptoms when medications do not improve a person's condition\n \nA surgeon can perform different types of operations to treat Crohn's disease:\n \n- small bowel resection - subtotal colectomy - proctocolectomy and ileostomy\n \nPatients will receive general anesthesia. Most patients will stay in the hospital for 3 to 7 days after the surgery. Full recovery may take 4 to 6 weeks.\n \nSmall bowel resection. Small bowel resection is surgery to remove part of a patient's small intestine. When a patient with Crohn's disease has a blockage or severe disease in the small intestine, a surgeon may need to remove that section of intestine. The two types of small bowel resection are\n \n- laparoscopicwhen a surgeon makes several small, half-inch incisions in the patient's abdomen. The surgeon inserts a laparoscopea thin tube with a tiny light and video camera on the endthrough the small incisions. The camera sends a magnified image from inside the body to a video monitor, giving the surgeon a close-up view of the small intestine. While watching the monitor, the surgeon inserts tools through the small incisions and removes the diseased or blocked section of small intestine. The surgeon will reconnect the ends of the intestine. - open surgerywhen a surgeon makes one incision about 6 inches long in the patient's abdomen. The surgeon will locate the diseased or blocked section of small intestine and remove or repair that section. The surgeon will reconnect the ends of the intestine.\n \nSubtotal colectomy. A subtotal colectomy, also called a large bowel resection, is surgery to remove part of a patient's large intestine. When a patient with Crohn's disease has a blockage, a fistula, or severe disease in the large intestine, a surgeon may need to remove that section of intestine. A surgeon can perform a subtotal colectomy by\n \n- laparoscopic colectomywhen a surgeon makes several small, half-inch incisions in the abdomen. While watching the monitor, the surgeon removes the diseased or blocked section of the large intestine. The surgeon will reconnect the ends of the intestine. - open surgerywhen a surgeon makes one incision about 6 to 8 inches long in the abdomen. The surgeon will locate the diseased or blocked section of small intestine and remove that section. The surgeon will reconnect the ends of the intestine.\n \nProctocolectomy and ileostomy. A proctocolectomy is surgery to remove a patient's entire colon and rectum. An ileostomy is a stoma, or opening in the abdomen, that a surgeon creates from a part of the ileumthe last section of the small intestine. The surgeon brings the end of the ileum through an opening in the patient's abdomen and attaches it to the skin, creating an opening outside of the patient's body. The stoma is about three-fourths of an inch to a little less than 2 inches wide and is most often located in the lower part of the patient's abdomen, just below the beltline.\n \nA removable external collection pouch, called an ostomy pouch or ostomy appliance, connects to the stoma and collects intestinal contents outside the patient's body. Intestinal contents pass through the stoma instead of passing through the anus. The stoma has no muscle, so it cannot control the flow of intestinal contents, and the flow occurs whenever peristalsis occurs. Peristalsis is the movement of the organ walls that propels food and liquid through the GI tract.\n \nPeople who have this type of surgery will have the ileostomy for the rest of their lives."} {"_id":"2492f21f-439b-4552-aa23-b66b26d5ebaf","text":"Researchers have not found that eating, diet, and nutrition cause Crohn's disease symptoms.

A person who is thinking of choosing a Medicare Advantage Plan should ask about the rules of the plan. The rules may specify which health care providers or hospitals a person may use. The plan may require a referral from a primary care provider to see a specialist. The plan may not cover medical expenses incurred during travel. How much a person has to pay out-of-pocket each year will vary by plan. People who have a Medicare Advantage Plan cannot have a Medigap plan to help pay out of-pocket costs. See the section on Medigap. Four types of Medicare Advantage Plans are available: - HMOs - preferred provider organizations (PPOs) - private fee for service plans - special needs plans for certain groups - Part D (prescription drug coverage) has a premium and covers some medications. Private insurance companies offer different Part D plans approved by Medicare. Costs and coverage vary by plan. A person who has few assets and earns less than 150 percent of the federal poverty level may qualify for extra help to pay Part D premiums and medication costs. People can apply for this help by calling the Social Security Administration, visiting www.socialsecurity.gov to apply online, visiting their local Social Security office, or contacting their state medical assistance (Medicaid) office. People can find the current-year guidelines at www.aspe.hhs.gov\/poverty or by calling Social Security at 18007721213, TTY 18003250778. People can find information and applications for Part D plans at www.medicare.gov. A person can also apply for Part D with an insurance company that sells one of these plans.\n \nOther Medicare health plans are for certain groups, such as frail people living in the community and people with multiple chronic illnesses, and include hospital and medical coverage. Some pay for prescribed medications, too. State health insurance programscalled Medicaidpartially finance and administer these services. The plans include the following:\n \n- Medicare Cost Plans are HMOs, like the ones offered as Medicare Advantage plans, only out-of-network providers are paid as if the policyholder had Original Medicare. Original Medicare is Medicare Part A and Part B. - Program of All-Inclusive Care for the Elderly (PACE) combines medical, social, and long-term care services for frail people who live and get health care in the community. - Medicare Innovation Projects are special projects that test improvements in Medicare coverage, payment, and quality of care.\n \nRead more about Medicare Cost Plans and Demonstration or Pilot Programs on the state Medicaid website at www.medicaid.gov or call 1800MEDICARE (18006334227). State Medicaid offices can provide more information about PACE. See the section on Medicaid.\n \nDoes Medicare cover diabetes services and supplies?\n \nMedicare helps pay for the diabetes services, supplies, and equipment listed below and for some preventive services for people who are at risk for diabetes. However, coinsurance or deductibles may apply. A person must have Medicare Part B or Medicare Part D to receive these covered services and supplies.\n \nMedicare Part B helps pay for\n \n- diabetes screening tests for people at risk of developing diabetes - diabetes self-management training - diabetes supplies such as glucose monitors, test strips, and lancets - insulin pumps and insulin if used with an insulin pump - counseling to help people who are obese lose weight - flu and pneumonia shots - foot exams and treatment for people with diabetes - eye exams to check for glaucoma and diabetic retinopathy - medical nutrition therapy services for people with diabetes or kidney disease, when referred by a health care provider - therapeutic shoes or inserts, in some cases\n \nMedicare Part D helps pay for\n \n- diabetes medications - insulin, excluding insulin used with an insulin pump - diabetes supplies such as needles and syringes for injecting insulin\n \nPeople who are in a Medicare Advantage Plan or other Medicare health plan should check their plans membership materials and call for details about how the plan provides the diabetes services, supplies, and medications covered by Medicare.\n \nRead more at www.medicare.gov\/publications\/pubs\/pdf\/11022.pdf (PDF, 1,023 KB) or call 1800MEDICARE (18006334227) to request the free booklet Medicares Coverage of Diabetes Supplies & Services.\n \nWhere can a person find more information about Medicare?\n \nA person can find more information about Medicare by\n \n- visiting the Medicare website - calling 1800MEDICARE\n \nMedicare website.

People can view their claims and order history, and see a description of covered preventive services.\n \n\n \nWhat is Medigap?\n \nA Medigap plan, also known as a Medicare supplement plan, can help pay what Original Medicare does not pay for covered services. Insurance companies sell Medigap coverage. People who have a Medicare Advantage plan cannot also have a Medigap plan. A person can buy a Medigap policy from any insurance company licensed to sell the policy in the persons home state.\n \nFor people who are 65 and older, federal law says that in the first 6 months a person has Part B, companies cannot deny an application or limit payment for anything Original Medicare covers. Some states make insurance companies sell at least one Medigap coverage plan to those under 65 with Medicare. State insurance offices can explain the plans in their state.

Autonomic neuropathy also affects other internal organs, causing problems with digestion, respiratory function, urination, sexual response, and vision. In addition, the system that restores blood glucose levels to normal after a hypoglycemic episode may be affected, resulting in loss of the warning symptoms of hypoglycemia.\n \nHypoglycemia Unawareness\n \nNormally, symptoms such as shakiness, sweating, and palpitations occur when blood glucose levels drop below 70 mg\/dL. In people with autonomic neuropathy, symptoms may not occur, making hypoglycemia difficult to recognize. Problems other than neuropathy can also cause hypoglycemia unawareness.\n \nHeart and Blood Vessels\n \nThe heart and blood vessels are part of the cardiovascular system, which controls blood circulation. Damage to nerves in the cardiovascular system interferes with the body's ability to adjust blood pressure and heart rate. As a result, blood pressure may drop sharply after sitting or standing, causing a person to feel light-headed or even to faint. Damage to the nerves that control heart rate can mean that the heart rate stays high, instead of rising and falling in response to normal body functions and physical activity.\n \nDigestive System\n \nNerve damage to the digestive system most commonly causes constipation. Damage can also cause the stomach to empty too slowly, a condition called gastroparesis. Severe gastroparesis can lead to persistent nausea and vomiting, bloating, and loss of appetite. Gastroparesis can also make blood glucose levels fluctuate widely, due to abnormal food digestion.\n \nNerve damage to the esophagus may make swallowing difficult, while nerve damage to the bowels can cause constipation alternating with frequent, uncontrolled diarrhea, especially at night. Problems with the digestive system can lead to weight loss.\n \nUrinary Tract and Sex Organs\n \nAutonomic neuropathy often affects the organs that control urination and sexual function. Nerve damage can prevent the bladder from emptying completely, allowing bacteria to grow in the bladder and kidneys and causing urinary tract infections. When the nerves of the bladder are damaged, urinary incontinence may result because a person may not be able to sense when the bladder is full or control the muscles that release urine.\n \nAutonomic neuropathy can also gradually decrease sexual response in men and women, although the sex drive may be unchanged. A man may be unable to have erections or may reach sexual climax without ejaculating normally. A woman may have difficulty with arousal, lubrication, or orgasm.\n \nSweat Glands\n \nAutonomic neuropathy can affect the nerves that control sweating. When nerve damage prevents the sweat glands from working properly, the body cannot regulate its temperature as it should. Nerve damage can also cause profuse sweating at night or while eating.\n \nEyes\n \nFinally, autonomic neuropathy can affect the pupils of the eyes, making them less responsive to changes in light.

During the exam, the doctor may check blood pressure, heart rate, muscle strength, reflexes, and sensitivity to position changes, vibration, temperature, or light touch.\n \nFoot Exams\n \nExperts recommend that people with diabetes have a comprehensive foot exam each year to check for peripheral neuropathy. People diagnosed with peripheral neuropathy need more frequent foot exams. A comprehensive foot exam assesses the skin, muscles, bones, circulation, and sensation of the feet. The doctor may assess protective sensation or feeling in the feet by touching them with a nylon monofilamentsimilar to a bristle on a hairbrushattached to a wand or by pricking them with a pin. People who cannot sense pressure from a pinprick or monofilament have lost protective sensation and are at risk for developing foot sores that may not heal properly. The doctor may also check temperature perception or use a tuning fork, which is more sensitive than touch pressure, to assess vibration perception.\n \nOther Tests\n \nThe doctor may perform other tests as part of the diagnosis.\n \n- Nerve conduction studies or electromyography are sometimes used to help determine the type and extent of nerve damage. Nerve conduction studies check the transmission of electrical current through a nerve. Electromyography shows how well muscles respond to electrical signals transmitted by nearby nerves. These tests are rarely needed to diagnose neuropathy. - A check of heart rate variability shows how the heart responds to deep breathing and to changes in blood pressure and posture. - Ultrasound uses sound waves to produce an image of internal organs. An ultrasound of the bladder and other parts of the urinary tract, for example, can be used to assess the structure of these organs and show whether the bladder empties completely after urination."} {"_id":"db838c9e-8ada-4647-a8cf-636bf0fb96b9","text":"The first treatment step is to bring blood glucose levels within the normal range to help prevent further nerve damage. Blood glucose monitoring, meal planning, physical activity, and diabetes medicines or insulin will help control blood glucose levels. Symptoms may get worse when blood glucose is first brought under control, but over time, maintaining lower blood glucose levels helps lessen symptoms. Good blood glucose control may also help prevent or delay the onset of further problems. As scientists learn more about the underlying causes of neuropathy, new treatments may become available to help slow, prevent, or even reverse nerve damage.\n \nAs described in the following sections, additional treatment depends on the type of nerve problem and symptom.\n \nPain Relief\n \nDoctors usually treat painful diabetic neuropathy with oral medications, although other types of treatments may help some people. People with severe nerve pain may benefit from a combination of medications or treatments and should consider talking with a health care provider about treatment options.\n \nMedications used to help relieve diabetic nerve pain include\n \n- tricyclic antidepressants, such as amitriptyline, imipramine, and desipramine (Norpramin, Pertofrane) - other types of antidepressants, such as duloxetine (Cymbalta), venlafaxine, bupropion (Wellbutrin), paroxetine (Paxil), and citalopram (Celexa) - anticonvulsants, such as pregabalin (Lyrica), gabapentin (Gabarone, Neurontin), carbamazepine, and lamotrigine (Lamictal) - opioids and opioidlike drugs, such as controlled-release oxycodone, an opioid; and tramadol (Ultram), an opioid that also acts as an antidepressant\n \nDuloxetine and pregabalin are approved by the U.S. Food and Drug Administration specifically for treating painful diabetic peripheral neuropathy.\n \nPeople do not have to be depressed for an antidepressant to help relieve their nerve pain. All medications have side effects, and some are not recommended for use in older adults or those with heart disease. Because over-the-counter pain medicines such as acetaminophen and ibuprofen may not work well for treating most nerve pain and can have serious side effects, some experts recommend avoiding these medications.\n \nTreatments that are applied to the skintypically to the feetinclude capsaicin cream and lidocaine patches (Lidoderm, Lidopain). Studies suggest that nitrate sprays or patches for the feet may relieve pain. Studies of alpha-lipoic acid, an antioxidant, and evening primrose oil suggest they may help relieve symptoms and improve nerve function in some patients.\n \nA device called a bed cradle can keep sheets and blankets from touching sensitive feet and legs. Acupuncture, biofeedback, or physical therapy may help relieve pain in some people. Treatments that involve electrical nerve stimulation, magnetic therapy, and laser or light therapy may be helpful but need further study. Researchers are also studying several new therapies in clinical trials.\n \nGastrointestinal Problems\n \nTo relieve mild symptoms of gastroparesisindigestion, belching, nausea, or vomitingdoctors suggest eating small, frequent meals; avoiding fats; and eating less fiber. When symptoms are severe, doctors may prescribe erythromycin to speed digestion, metoclopramide to speed digestion and help relieve nausea, or other medications to help regulate digestion or reduce stomach acid secretion.\n \nTo relieve diarrhea or other bowel problems, doctors may prescribe an antibiotic such as tetracycline, or other medications as appropriate.\n \nDizziness and Weakness\n \nSitting or standing slowly may help prevent the light-headedness, dizziness, or fainting associated with blood pressure and circulation problems. Raising the head of the bed or wearing elastic stockings may also help. Some people benefit from increased salt in the diet and treatment with salt-retaining hormones. Others benefit from high blood pressure medications. Physical therapy can help when muscle weakness or loss of coordination is a problem.\n \nUrinary and Sexual Problems\n \nTo clear up a urinary tract infection, the doctor will probably prescribe an antibiotic. Drinking plenty of fluids will help prevent another infection. People who have incontinence should try to urinate at regular intervalsevery 3 hours, for examplebecause they may not be able to tell when the bladder is full.\n \nTo treat erectile dysfunction in men, the doctor will first do tests to rule out a hormonal cause. Several methods are available to treat erectile dysfunction caused by neuropathy. Medicines are available to help men have and maintain erections by increasing blood flow to the penis. Some are oral medications and others are injected into the penis or inserted into the urethra at the tip of the penis. Mechanical vacuum devices can also increase blood flow to the penis. Another option is to surgically implant an inflatable or semirigid device in the penis.\n \nVaginal lubricants may be useful for women when neuropathy causes vaginal dryness. To treat problems with arousal and orgasm, the doctor may refer women to a gynecologist.\n \nFoot Care\n \nPeople with neuropathy need to take special care of their feet. The nerves to the feet are the longest in the body and are the ones most often affected by neuropathy. Loss of sensation in the feet means that sores or injuries may not be noticed and may become ulcerated or infected. Circulation problems also increase the risk of foot ulcers. Smoking increases the risk of foot problems and amputation. A health care provider may be able to provide help with quitting smoking.\n \nMore than 60 percent of all nontraumatic lower-limb amputations in the United States occur in people with diabetes. Nontraumatic amputations are those not caused by trauma such as severe injuries from an accident. In 2004, about 71,000 nontraumatic amputations were performed in people with diabetes. Comprehensive foot care programs can reduce amputation rates by 45 to 85 percent.\n \nCareful foot care involves\n \n- cleaning the feet daily using warmnot hotwater and a mild soap. Soaking the feet should be avoided. A soft towel can be used to dry the feet and between the toes. - inspecting the feet and toes every day for cuts, blisters, redness, swelling, calluses, or other problems. Using a mirrorhandheld or placed on the floormay be helpful in checking the bottoms of the feet, or another person can help check the feet. A health care provider should be notified of any problems. - using lotion to moisturize the feet. Getting lotion between the toes should be avoided. - filing corns and calluses gently with a pumice stone after a bath or shower. - cutting toenails to the shape of the toes and filing the edges with an emery board each week or when needed. - always wearing shoes or slippers to protect feet from injuries. Wearing thick, soft, seamless socks can prevent skin irritation. - wearing shoes that fit well and allow the toes to move. New shoes can be broken in gradually by first wearing them for only an hour at a time. - looking shoes over carefully before putting them on and feeling the insides to make sure the shoes are free of tears, sharp edges, or objects that might injure the feet.\n \nPeople who need help taking care of their feet should consider making an appointment to see a foot doctor, also called a podiatrist."} {"_id":"e73e10e8-b0a9-4f69-a9fc-97c8beceacfb","text":"- Diabetic neuropathies are nerve disorders caused by many of the abnormalities common to diabetes, such as high blood glucose. - Neuropathy can affect nerves throughout the body, causing numbness and sometimes pain in the hands, arms, feet, or legs, and problems with the digestive tract, heart, sex organs, and other body systems. - Treatment first involves bringing blood glucose levels within the normal range.

Growth hormone from animals did not work in humans. Human growth hormone (pituitary hGH) was therefore made from human pituitary glands by the National Hormone and Pituitary Program (NHPP), funded by the U.S. Department of Health and Human Services (HHS). From 1963 to 1985, the NHPP sent pituitary hGH to hundreds of doctors across the country. As a part of research studies, doctors used the hormone to treat nearly 7,700 children for failure to grow.\n \nIn 1985, the HHS learned that three young men treated with pituitary hGH died of Creutzfeldt-Jakob disease (CJD), a rare and incurable brain disease. The HHS believed these illnesses were related to pituitary hGH. The HHS immediately stopped the distribution of the hormone and began a national study to learn more about how pituitary hGH treatment may have caused this problem. The HHS continues to monitor individuals who received pituitary hGH through the NHPP for CJD."} {"_id":"6376a2a5-fb7a-42bf-96bf-3943bf060638","text":"The HHS has identified 29 cases of CJD among the nearly 7,700 people in the United States who received NHPP pituitary hGH. None of the 29 people who got CJD began treatment with pituitary hGH after 1977, the year that the NHPP began producing pituitary hGH in a laboratory (headed by Dr. Albert Parlow) using a new purification step. Today, the growth hormone used to treat patients is made biosynthetically and not from human pituitary glands. Biosynthetic growth hormone (bGH), also known as recombinant human growth hormone (rhGH), poses no threat of infection with CJD.\n \nBased on NHPP records, the HHS estimated 7,700 people were treated with pituitary hGH from the NHPP. Of these, the HHS got the names and addresses of 6,272 from their doctors and treatment centers so that their health could be monitored. Another 1,400 people are believed to have been treated with pituitary hGH; however, the HHS does not have their names and addresses. The HHS hoped to learn about CJD and other health problems in the unmonitored group of 1,400 and notified many doctors about the problem of CJD, asking them to report CJD among people treated with pituitary hGH. The HHS has learned that five of the 29 people with confirmed CJD were among the 1,400 people the HHS was not able to identify and study.\n \nSome U.S. laboratories that made pituitary hGH for the NHPP also made hGH for use in other countries. The HHS learned that six people in New Zealand and two people in Brazil who received U.S.-made pituitary hGH may also have gotten CJD. A total of 37 people who were treated with pituitary hGH made in the United States may have gotten CJD.\n \nBefore bGH was available, several pharmaceutical companies made pituitary hGH. Some children treated in the U.S. received hormone produced by these companies when NHPP hGH was not available to them. Some of the 29 people with confirmed CJD received hGH from both the NHPP and a pharmaceutical company. Recently, the HHS has learned of an individual treated in the U.S. who developed CJD and received only commercial pituitary hGH.

We don't know why this ratesix out of 49 (12.2 percent)is so high in those in New Zealand who received American hormone. HHS scientists believe that this U.S.-made hormone did not undergo the same filtering process used in the United States when the hormone was put into vials. In addition, some hormone preparations sent to New Zealand were not distributed in the United States.\n \nNew Zealand has little information on the hormone preparations used to treat the people who got CJD. Information provided to the HHS from medical authorities in New Zealand indicated the following dates of pituitary hGH treatment for the six New Zealand patients who developed CJD: 1964 to 1966, 1964 to 1970, 1965 to 1972, 1966 to 1972, 1967 to 1969, and 1970 to 1973. With no common period of treatment, it is unlikely that a single preparation exposed all six patients to CJD.\n \nThere is some information on the hormone sent to New Zealand from the lab that also produced hormone for the NHPP before 1977. Some preparations and components of preparations were used in both countries and others were distributed only in the United States or in New Zealand.\n \nThe time between the start of pituitary hGH treatment and the first sign of CJD symptoms was similar in the 29 United States patients (14 to 44 years) and the six New Zealand patients (17 to 37 years). The New Zealand patients who got CJD were treated with pituitary hGH for an average of 4.3 years. In the United States, average treatment time was 8.4 years in patients who got CJD.\n \nIn France, 119 people with CJD were among the 1,700 treated with pituitary hGH. The pattern of exposure to CJD in France is very different from the pattern in the United States. In France, people who received pituitary hGH in 1984 and 1985 appear to be at highest risk for CJD. We have learned from animal studies that when scientists injected a greater amount of CJD infectious agent into an animal, it took less time for CJD to develop. Because of the larger number of people with CJD and shorter times between treatment and CJD onset in France, the level of infection in French hormone was probably higher than in the U.S. hormone. The purification procedure used in France differed from that begun in 1977 in the United States.\n \nThe United Kingdom has reported 75 people with CJD among 1,849 who received pituitary hGH. Experts have also found CJD in two people in Holland, two people in Brazil, and one each in Australia, Austria, Qatar, and Ireland. France, the United Kingdom, Holland, and Australia made their own hormone. The Brazilian patients got pituitary hGH from a U.S. lab that also made NHPP hormone before 1977. This was a different lab than the U.S. lab that made hormone for New Zealand. The Qatar patient received pituitary hGH made in France. The Austrian patient received pituitary hGH made by a pharmaceutical company.

Some of these people also had problems making other pituitary hormones. One of these hormones tells the adrenal glands to make cortisol, a hormone needed for life. People lacking this hormone are at risk of death from adrenal crisis, but adrenal crisis can be prevented. More pituitary hGH recipients have died from adrenal crisis than from CJD. Pituitary hGH did not cause adrenal problems, but some people who received hGH have a pituitary problem that puts them at risk for adrenal crisis. Please read the health alert and discuss this information with your doctor.\n \nBesides CJD, no other serious or fatal health risks from pituitary hGH treatment have been found.\n \nMad Cow Disease\n \nStarting in 1996, reports of a new form of CJD in young people who lived in the United Kingdom have raised concerns worldwide.\n \nSince at least 1985, some cattle in the United Kingdom have developed a disease called bovine spongiform encephalopathy (BSE), or \"mad cow\" disease. \"Mad cow\" disease is a sickness in cattle that is caused by an agent that is similar, but not identical, to the agents that cause the most common forms of CJD in people. Individuals who consume products made from cattle infected with the agent that causes \"mad cow\" disease can become infected with the agent themselves and develop the human form of \"mad cow\" disease, called variant CJD (vCJD). In humans, vCJD and the more common forms of CJD (those without the word \"variant\") are separate diseases. As of November 2012, 227 cases of vCJD were confirmed worldwide, mostly from the United Kingdom. Researchers believe all but three of these 227 individuals got vCJD by eating beef from animals with \"mad cow\" disease. The three exceptions were persons who are believed to have developed vCJD because they received infected blood from a donor who had acquired the agent by eating beef from animals with \"mad cow\" disease.\n \nIn the United States, three cases of vCJD have been found. According to the Centers for Disease Control and Prevention (CDC), the investigation of these three cases indicated that they most likely acquired their infection in the United Kingdom (two cases) and Saudi Arabia (one case).\n \nPeople who received pituitary hGH are not at higher risk for vCJD.\n \nAIDS\n \nHIV, also known as the human immunodeficiency virus, causes AIDS. Pituitary hGH does not cause AIDS. HIV is destroyed by the methods used to make pituitary hGH. People who have been treated with pituitary hGH do not have a higher risk for AIDS.\n \nLow Levels of GH in Adults\n \nSome people who received pituitary hGH as children may have low levels of GH as adults and might therefore benefit from bGH as adults. People with low levels of growth hormone as adults may have symptoms or changes like these:\n \n- more body fat - less muscle - less bone mass - less strength - less energy\n \nIf you lacked GH as a child and have these problems as an adult, ask your doctor whether they might be due to low GH. Because these conditions are common in many people, they are not always due to low GH. Studies have shown that GH treatment in adults with low GH reduces fat and increases muscle mass. Effects on strength, energy, and bone fractures in GH-deficient adults receiving GH replacement are not as clear.\n \nToday, GH is completely synthetic. It is not made from human pituitaries. It poses no threat of contamination. The Human Growth Foundation (HGF) is one source of information about growth-related disorders. The Foundation can be reached at 18004516434.\n \nCancer\n \nHHS studies of people treated with pituitary hGH supplied by the NHPP show no increased risk of cancer in those who did not have tumors before pituitary hGH treatment. Many people who received NHPP pituitary hGH had brain tumors that caused their lack of GH. People who have had one tumor have an increased risk for getting other tumors.\n \nIn previous updates, we reported that in 1988, Japanese doctors reported an increased risk of leukemia in people treated with GH. Subsequent studies of individuals who were given pituitary hGH in the United States, Japan, and the United Kingdom found no higher rate of leukemia among those who did not have tumors and\/or radiation before treatment with pituitary hGH.\n \nEmotional Problems\n \nNo studies have shown that pituitary hGH causes changes in personality, emotional problems, or suicide."} {"_id":"ad72cd9f-5312-44fb-9257-6ca3d5790101","text":"CJD does not cause the same symptoms in everyone.

How long a person was treated:\n \n- In the United States, the average length of time for pituitary hGH treatment through the NHPP was about 3 years. For those individuals who developed CJD, the average length of treatment was about 8.4 years. - Even though longer treatment time increased the risk for CJD in the United States, in other countries CJD has developed after shorter treatment periods.\n \n2. When a person was treated:\n \n- All of the 29 individuals treated with NHPP hGH who got CJD in the United States started pituitary hGH before 1977. No CJD has been reported in Americans who began treatment with NHPP hormone after 1977, when production of NHPP hormone was moved to a laboratory (headed by Dr. Albert Parlow) that used a new method of purifying pituitary hGH. Research in animals showed the newer purification steps introduced in 1977 reduced the risk of CJD transmission. Recently, an analysis of NHPP hGH recipients was completed taking into account the differences in follow-up time and the duration of treatment of recipients starting treatment before or after 1977. That analysis found that the new purification steps greatly reduced and may have eliminated the risk for CJD infection. - Two cases of CJD have been reported in individuals who received commercially prepared pituitary hGH. An Austrian person was treated with pituitary hGH (Crescormon, from Kabi Pharma) for 14 months and died from CJD 22 years later. An American who was too tall to be eligible for NHPP hormone was treated with pituitary hGH made by two pharmaceutical companies (Asellacrin, from Serono, and Crescormon, from Kabi Pharma). This individual was treated with commercial hGH for 23 months and died just over 26 years later. The methods used to produce these commercial hormone preparations were not identical to the method used in Dr. Parlow's laboratory but did include a version of the important new purification step that has been shown to reduce CJD infectivity. - Overall, one out of about 265 people (29 out of about 7,700 people) who were treated with NHPP pituitary hGH got CJD. - However, one in about 91 people who began treatment before 1977 got CJD. - People who started treatment before 1970 are at even higher risk.

We believe that CJD did not come from a single infected pituitary gland or preparation. Prior to 1977, in an effort to extract as much hormone as possible from the pituitary glands, the glands were often processed repeatedly. Hormone extracted from the same pituitaries was often included in many hormone preparations. Also, patients who got CJD were treated on average for 8.4 years and received many different hormone preparations. This makes it very difficult to identify any preparation associated with transmitting CJD.\n \nDoctors wanted to see if a specific preparation of pituitary hGH could transmit CJD. To try to find the pituitary hGH that could have caused CJD, HHS researchers did two things:\n \n1. They set up a test in animals, injecting samples of all available preparations of pituitary hGH directly into the brains of monkeys. CJD develops more rapidly if injected into the brain than under the skin, as hGH was used in people. The animals were watched for 10 years. The brains of all animals were examined for signs of CJD. If an animal got sick with CJD, it would help researchers to understand which vials of pituitary hGH were contaminated with the agent that causes CJD.\n \n2. They studied people treated with pituitary hGH to see who got CJD and which hormone preparation they might have received based on which preparations were sent to their doctor.\n \nResults:\n \n- The animal tests did not help find the pituitary hGH that might have caused CJD. One animal developed the disease 5 years after injection of pituitary hGH. Two other animals that received injections from different vials of the same pituitary hGH preparation did not develop CJD. - None of the people who developed CJD are known to have received the hormone preparation that made the animal sick. At most, two patients (whose records are incomplete) may have received this pituitary hGH preparation. Because of this, we do not believe that the patients who received the hormone preparation that transmitted CJD to the animal have a greater risk of developing CJD than others treated with pituitary hGH. Because each preparation of pituitary hGH was used to fill multiple vials, it is not known if CJD contamination was spread evenly among all vials of pituitary hGH that came from a particular preparation. It's possible that one vial got more contamination and another got little or none from the same preparation of pituitary hGH. It is believed that multiple preparations of pituitary hGH probably had very low levels of the CJD infectious agent. With such low levels of contamination, some vials of a preparation might carry CJD while other vials would not.

When this protein is found, it helps make a diagnosis of CJD. It is much easier and safer to take a sample of spinal fluid than to do a brain biopsy. Unfortunately, this test cannot identify CJD in patients who do not have symptoms. The test cannot predict who may develop CJD in the future.\n \nResearchers from many countries, including the United States, have reported success using MRI to diagnose CJD and vCJD in people with symptoms of the disease.

Some people have gotten CJD from medical procedures such as pituitary hGH injections, tissue grafts, or corneal transplants. Scientists don't fully understand what causes CJD. Evidence suggests that a unique infectious agent called a prion [PREE-on] may be the cause. A prion is an unusual infectious agent because it contains no genetic material. It is a protein that takes on different forms. In its normal, harmless form, the protein is curled into a spiral. In its infectious form, the protein folds into an abnormal shape. Somehow, these abnormal proteins change the shape of normal proteins. This change begins a serious chain reaction that results in brain problems.\n \nPeople with inherited CJD have an abnormal gene that leads to changes in their prion protein. This gene makes the protein likely to assume the abnormal shape. Exposure to the abnormal form of the protein can also occur through injection of contaminated pituitary hGH, tissue grafts, and corneal transplants and through exposures to infected brain tissue.\n \nIf CJD results from a defect in protein folding, it may be possible to identify drugs that can help the prion protein assume its proper shape. Such drugs would slow or stop the progress of the disease. Treatments like these are being studied by researchers.

Common sources of E. coli include raw or undercooked hamburger, unpasteurized fruit juices and milk, and fresh produce. - Listeria monocytogenes (L. monocytogenes), which has been found in raw and undercooked meats, unpasteurized milk, soft cheeses, and ready-to-eat deli meats and hot dogs. - Vibrio, a bacterium that may contaminate fish or shellfish. - Clostridium botulinum (C. botulinum), a bacterium that may contaminate improperly canned foods and smoked and salted fish.\n \nViruses\n \nViruses are tiny capsules, much smaller than bacteria, that contain genetic material. Viruses cause infections that can lead to sickness. People can pass viruses to each other. Viruses are present in the stool or vomit of people who are infected. People who are infected with a virus may contaminate food and drinks, especially if they do not wash their hands thoroughly after using the bathroom.\n \nCommon sources of foodborne viruses include\n \n- food prepared by a person infected with a virus - shellfish from contaminated water - produce irrigated with contaminated water\n \nCommon foodborne viruses include\n \n- norovirus, which causes inflammation of the stomach and intestines - hepatitis A, which causes inflammation of the liver\n \nParasites\n \nParasites are tiny organisms that live inside another organism. In developed countries such as the United States, parasitic infections are relatively rare.\n \nCryptosporidium parvum and Giardia intestinalis are parasites that are spread through water contaminated with the stools of people or animals who are infected. Foods that come into contact with contaminated water during growth or preparation can become contaminated with these parasites. Food preparers who are infected with these parasites can also contaminate foods if they do not thoroughly wash their hands after using the bathroom and before handling food.\n \nTrichinella spiralis is a type of roundworm parasite. People may be infected with this parasite by consuming raw or undercooked pork or wild game.\n \nChemicals\n \nHarmful chemicals that cause illness may contaminate foods such as\n \n- fish or shellfish, which may feed on algae that produce toxins, leading to high concentrations of toxins in their bodies. Some types of fish, including tuna and mahi mahi, may be contaminated with bacteria that produce toxins if the fish are not properly refrigerated before they are cooked or served. - certain types of wild mushrooms. - unwashed fruits and vegetables that contain high concentrations of pesticides."} {"_id":"c5bbe7ef-9802-4d75-8c42-0c4034ca8dff","text":"Anyone can get a foodborne illness.

When dehydrated, the body lacks enough fluid and electrolytesminerals in salts, including sodium, potassium, and chlorideto function properly. Infants, children, older adults, and people with weak immune systems have the greatest risk of becoming dehydrated.\n \nSigns of dehydration are\n \n- excessive thirst - infrequent urination - dark-colored urine - lethargy, dizziness, or faintness\n \nSigns of dehydration in infants and young children are\n \n- dry mouth and tongue - lack of tears when crying - no wet diapers for 3 hours or more - high fever - unusually cranky or drowsy behavior - sunken eyes, cheeks, or soft spot in the skull\n \nAlso, when people are dehydrated, their skin does not flatten back to normal right away after being gently pinched and released.\n \nSevere dehydration may require intravenous fluids and hospitalization. Untreated severe dehydration can cause serious health problems such as organ damage, shock, or comaa sleeplike state in which a person is not conscious.\n \nHUS\n \nHemolytic uremic syndrome is a rare disease that mostly affects children younger than 10 years of age. HUS develops when E. coli bacteria lodged in the digestive tract make toxins that enter the bloodstream. The toxins start to destroy red blood cells, which help the blood to clot, and the lining of the blood vessels.\n \nIn the United States, E. coli O157:H7 infection is the most common cause of HUS, but infection with other strains of E. coli, other bacteria, and viruses may also cause HUS. A recent study found that about 6 percent of people with E. coli O157:H7 infections developed HUS. Children younger than age 5 have the highest risk, but females and people age 60 and older also have increased risk.3\n \nSymptoms of E. coli O157:H7 infection include diarrhea, which may be bloody, and abdominal pain, often accompanied by nausea, vomiting, and fever. Up to a week after E. coli symptoms appear, symptoms of HUS may develop, including irritability, paleness, and decreased urination. HUS may lead to acute renal failure, which is a sudden and temporary loss of kidney function. HUS may also affect other organs and the central nervous system. Most people who develop HUS recover with treatment. Research shows that in the United States between 2000 and 2006, fewer than 5 percent of people who developed HUS died of the disorder. Older adults had the highest mortality rateabout one-third of people age 60 and older who developed HUS died.3\n \nStudies have shown that some children who recover from HUS develop chronic complications, including kidney problems, high blood pressure, and diabetes.\n \nOther Complications\n \nSome foodborne illnesses lead to other serious complications. For example, C. botulinum and certain chemicals in fish and seafood can paralyze the muscles that control breathing. L. monocytogenes can cause spontaneous abortion or stillbirth in pregnant women.\n \nResearch suggests that acute foodborne illnesses may lead to chronic disorders, including\n \n- reactive arthritis, a type of joint inflammation that usually affects the knees, ankles, or feet. Some people develop this disorder following foodborne illnesses caused by certain bacteria, including C. jejuni and Salmonella. Reactive arthritis usually lasts fewer than 6 months, but this condition may recur or become chronic arthritis.4 - irritable bowel syndrome (IBS), a disorder of unknown cause that is associated with abdominal pain, bloating, and diarrhea or constipation or both. Foodborne illnesses caused by bacteria increase the risk of developing IBS.5 - Guillain-Barr syndrome, a disorder characterized by muscle weakness or paralysis that begins in the lower body and progresses to the upper body. This syndrome may occur after foodborne illnesses caused by bacteria, most commonly C. jejuni.

During the procedure, the patient will stand or sit in front of an x-ray machine and drink barium, a chalky liquid. Infants lie on a table and a health care provider gives them barium through a tiny tube placed in the nose that runs into the stomach. Barium coats the GI tract, making signs of obstruction or other problems that can cause vomiting show up more clearly on x rays. A patient may experience bloating and nausea for a short time after the test. The upper GI series can show other problems that may be causing symptoms, such as an ulcer or obstruction.\n \nAbdominal ultrasound.

A health care provider may give a patient a liquid anesthetic to gargle or may spray anesthetic on the back of the patients throat. A nurse or technician will place an IV needle in a vein in the arm to administer sedation or anesthesia. Sedatives or anesthesia help a patient stay relaxed and comfortable. The gastroenterologist carefully inserts the endoscope into the mouth and feeds the endoscope down the esophagus and into the stomach and duodenum. A small camera mounted on the endoscope transmits a video image to a monitor, allowing close examination of the intestinal lining. The upper GI endoscopy can show other problems that may be causing symptoms, such as an ulcer. A gastroenterologist may obtain a biopsya procedure that involves taking a small piece of tissue for examination with a microscopeof the small-intestinal lining during an upper GI endoscopy.

In diabetes, the bodys cells are starved of energy despite high blood glucose levels.\n \nOver time, high blood glucose damages nerves and blood vessels, leading to complications such as heart disease, stroke, kidney disease, blindness, dental disease, and amputations. Other complications of diabetes may include increased susceptibility to other diseases, loss of mobility with aging, depression, and pregnancy problems. No one is certain what starts the processes that cause diabetes, but scientists believe genes and environmental factors interact to cause diabetes in most cases.\n \nThe two main types of diabetes are type 1 diabetes and type 2 diabetes. A third type, gestational diabetes, develops only during pregnancy. Other types of diabetes are caused by defects in specific genes, diseases of the pancreas, certain drugs or chemicals, infections, and other conditions. Some people show signs of both type 1 and type 2 diabetes."} {"_id":"e6807718-d30a-4c5a-809e-969c0a2a1c3b","text":"Type 1 diabetes is caused by a lack of insulin due to the destruction of insulin-producing beta cells in the pancreas. In type 1 diabetesan autoimmune diseasethe bodys immune system attacks and destroys the beta cells. Normally, the immune system protects the body from infection by identifying and destroying bacteria, viruses, and other potentially harmful foreign substances. But in autoimmune diseases, the immune system attacks the bodys own cells. In type 1 diabetes, beta cell destruction may take place over several years, but symptoms of the disease usually develop over a short period of time.\n \nType 1 diabetes typically occurs in children and young adults, though it can appear at any age. In the past, type 1 diabetes was called juvenile diabetes or insulin-dependent diabetes mellitus.\n \nLatent autoimmune diabetes in adults (LADA) may be a slowly developing kind of type 1 diabetes. Diagnosis usually occurs after age 30. In LADA, as in type 1 diabetes, the bodys immune system destroys the beta cells. At the time of diagnosis, people with LADA may still produce their own insulin, but eventually most will need insulin shots or an insulin pump to control blood glucose levels.\n \nGenetic Susceptibility\n \nHeredity plays an important part in determining who is likely to develop type 1 diabetes. Genes are passed down from biological parent to child. Genes carry instructions for making proteins that are needed for the bodys cells to function. Many genes, as well as interactions among genes, are thought to influence susceptibility to and protection from type 1 diabetes. The key genes may vary in different population groups. Variations in genes that affect more than 1 percent of a population group are called gene variants.\n \nCertain gene variants that carry instructions for making proteins called human leukocyte antigens (HLAs) on white blood cells are linked to the risk of developing type 1 diabetes. The proteins produced by HLA genes help determine whether the immune system recognizes a cell as part of the body or as foreign material. Some combinations of HLA gene variants predict that a person will be at higher risk for type 1 diabetes, while other combinations are protective or have no effect on risk.\n \nWhile HLA genes are the major risk genes for type 1 diabetes, many additional risk genes or gene regions have been found. Not only can these genes help identify people at risk for type 1 diabetes, but they also provide important clues to help scientists better understand how the disease develops and identify potential targets for therapy and prevention.\n \nGenetic testing can show what types of HLA genes a person carries and can reveal other genes linked to diabetes. However, most genetic testing is done in a research setting and is not yet available to individuals. Scientists are studying how the results of genetic testing can be used to improve type 1 diabetes prevention or treatment.\n \nAutoimmune Destruction of Beta Cells\n \nIn type 1 diabetes, white blood cells called T cells attack and destroy beta cells. The process begins well before diabetes symptoms appear and continues after diagnosis. Often, type 1 diabetes is not diagnosed until most beta cells have already been destroyed. At this point, a person needs daily insulin treatment to survive. Finding ways to modify or stop this autoimmune process and preserve beta cell function is a major focus of current scientific research.\n \nRecent research suggests insulin itself may be a key trigger of the immune attack on beta cells. The immune systems of people who are susceptible to developing type 1 diabetes respond to insulin as if it were a foreign substance, or antigen. To combat antigens, the body makes proteins called antibodies. Antibodies to insulin and other proteins produced by beta cells are found in people with type 1 diabetes. Researchers test for these antibodies to help identify people at increased risk of developing the disease. Testing the types and levels of antibodies in the blood can help determine whether a person has type 1 diabetes, LADA, or another type of diabetes.\n \nEnvironmental Factors\n \nEnvironmental factors, such as foods, viruses, and toxins, may play a role in the development of type 1 diabetes, but the exact nature of their role has not been determined. Some theories suggest that environmental factors trigger the autoimmune destruction of beta cells in people with a genetic susceptibility to diabetes. Other theories suggest that environmental factors play an ongoing role in diabetes, even after diagnosis.\n \nViruses and infections. A virus cannot cause diabetes on its own, but people are sometimes diagnosed with type 1 diabetes during or after a viral infection, suggesting a link between the two. Also, the onset of type 1 diabetes occurs more frequently during the winter when viral infections are more common. Viruses possibly associated with type 1 diabetes include coxsackievirus B, cytomegalovirus, adenovirus, rubella, and mumps. Scientists have described several ways these viruses may damage or destroy beta cells or possibly trigger an autoimmune response in susceptible people. For example, anti-islet antibodies have been found in patients with congenital rubella syndrome, and cytomegalovirus has been associated with significant beta cell damage and acute pancreatitisinflammation of the pancreas. Scientists are trying to identify a virus that can cause type 1 diabetes so that a vaccine might be developed to prevent the disease.\n \nInfant feeding practices. Some studies have suggested that dietary factors may raise or lower the risk of developing type 1 diabetes. For example, breastfed infants and infants receiving vitamin D supplements may have a reduced risk of developing type 1 diabetes, while early exposure to cows milk and cereal proteins may increase risk. More research is needed to clarify how infant nutrition affects the risk for type 1 diabetes.\n \nRead more in the Centers for Disease Control and Preventions (CDCs) publication National Diabetes Statistics Report, 2014 at www.cdc.gov for information about research studies related to type 1 diabetes."} {"_id":"11ebde33-72e3-457a-b42d-0839066ce622","text":"Type 2 diabetesthe most common form of diabetesis caused by a combination of factors, including insulin resistance, a condition in which the bodys muscle, fat, and liver cells do not use insulin effectively. Type 2 diabetes develops when the body can no longer produce enough insulin to compensate for the impaired ability to use insulin. Symptoms of type 2 diabetes may develop gradually and can be subtle; some people with type 2 diabetes remain undiagnosed for years.\n \nType 2 diabetes develops most often in middle-aged and older people who are also overweight or obese. The disease, once rare in youth, is becoming more common in overweight and obese children and adolescents. Scientists think genetic susceptibility and environmental factors are the most likely triggers of type 2 diabetes.\n \nGenetic Susceptibility\n \nGenes play a significant part in susceptibility to type 2 diabetes. Having certain genes or combinations of genes may increase or decrease a persons risk for developing the disease. The role of genes is suggested by the high rate of type 2 diabetes in families and identical twins and wide variations in diabetes prevalence by ethnicity. Type 2 diabetes occurs more frequently in African Americans, Alaska Natives, American Indians, Hispanics\/Latinos, and some Asian Americans, Native Hawaiians, and Pacific Islander Americans than it does in non-Hispanic whites.\n \nRecent studies have combined genetic data from large numbers of people, accelerating the pace of gene discovery. Though scientists have now identified many gene variants that increase susceptibility to type 2 diabetes, the majority have yet to be discovered. The known genes appear to affect insulin production rather than insulin resistance. Researchers are working to identify additional gene variants and to learn how they interact with one another and with environmental factors to cause diabetes.\n \nStudies have shown that variants of the TCF7L2 gene increase susceptibility to type 2 diabetes. For people who inherit two copies of the variants, the risk of developing type 2 diabetes is about 80 percent higher than for those who do not carry the gene variant.1 However, even in those with the variant, diet and physical activity leading to weight loss help delay diabetes, according to the Diabetes Prevention Program (DPP), a major clinical trial involving people at high risk.\n \nGenes can also increase the risk of diabetes by increasing a persons tendency to become overweight or obese. One theory, known as the thrifty gene hypothesis, suggests certain genes increase the efficiency of metabolism to extract energy from food and store the energy for later use. This survival trait was advantageous for populations whose food supplies were scarce or unpredictable and could help keep people alive during famine. In modern times, however, when high-calorie foods are plentiful, such a trait can promote obesity and type 2 diabetes.\n \nObesity and Physical Inactivity\n \nPhysical inactivity and obesity are strongly associated with the development of type 2 diabetes. People who are genetically susceptible to type 2 diabetes are more vulnerable when these risk factors are present.\n \nAn imbalance between caloric intake and physical activity can lead to obesity, which causes insulin resistance and is common in people with type 2 diabetes. Central obesity, in which a person has excess abdominal fat, is a major risk factor not only for insulin resistance and type 2 diabetes but also for heart and blood vessel disease, also called cardiovascular disease (CVD). This excess belly fat produces hormones and other substances that can cause harmful, chronic effects in the body such as damage to blood vessels.\n \nThe DPP and other studies show that millions of people can lower their risk for type 2 diabetes by making lifestyle changes and losing weight. The DPP proved that people with prediabetesat high risk of developing type 2 diabetescould sharply lower their risk by losing weight through regular physical activity and a diet low in fat and calories. In 2009, a follow-up study of DPP participantsthe Diabetes Prevention Program Outcomes Study (DPPOS)showed that the benefits of weight loss lasted for at least 10 years after the original study began.2\n \nRead more about the DPP, funded under National Institutes of Health (NIH) clinical trial number NCT00004992, and the DPPOS, funded under NIH clinical trial number NCT00038727 in Diabetes Prevention Program.\n \nInsulin Resistance\n \nInsulin resistance is a common condition in people who are overweight or obese, have excess abdominal fat, and are not physically active. Muscle, fat, and liver cells stop responding properly to insulin, forcing the pancreas to compensate by producing extra insulin. As long as beta cells are able to produce enough insulin, blood glucose levels stay in the normal range. But when insulin production falters because of beta cell dysfunction, glucose levels rise, leading to prediabetes or diabetes.\n \nAbnormal Glucose Production by the Liver\n \nIn some people with diabetes, an abnormal increase in glucose production by the liver also contributes to high blood glucose levels. Normally, the pancreas releases the hormone glucagon when blood glucose and insulin levels are low. Glucagon stimulates the liver to produce glucose and release it into the bloodstream. But when blood glucose and insulin levels are high after a meal, glucagon levels drop, and the liver stores excess glucose for later, when it is needed. For reasons not completely understood, in many people with diabetes, glucagon levels stay higher than needed. High glucagon levels cause the liver to produce unneeded glucose, which contributes to high blood glucose levels. Metformin, the most commonly used drug to treat type 2 diabetes, reduces glucose production by the liver.\n \nThe Roles of Insulin and Glucagon in Normal Blood Glucose Regulation\n \nA healthy persons body keeps blood glucose levels in a normal range through several complex mechanisms. Insulin and glucagon, two hormones made in the pancreas, help regulate blood glucose levels:\n \n- Insulin, made by beta cells, lowers elevated blood glucose levels. - Glucagon, made by alpha cells, raises low blood glucose levels.\n \n- Insulin helps muscle, fat, and liver cells absorb glucose from the bloodstream, lowering blood glucose levels. - Insulin stimulates the liver and muscle tissue to store excess glucose. The stored form of glucose is called glycogen. - Insulin also lowers blood glucose levels by reducing glucose production in the liver.\n \n- Glucagon signals the liver and muscle tissue to break down glycogen into glucose, which enters the bloodstream and raises blood glucose levels. - If the body needs more glucose, glucagon stimulates the liver to make glucose from amino acids.\n \nMetabolic Syndrome\n \nMetabolic syndrome, also called insulin resistance syndrome, refers to a group of conditions common in people with insulin resistance, including\n \n- higher than normal blood glucose levels - increased waist size due to excess abdominal fat - high blood pressure - abnormal levels of cholesterol and triglycerides in the blood\n \nCell Signaling and Regulation\n \nCells communicate through a complex network of molecular signaling pathways. For example, on cell surfaces, insulin receptor molecules capture, or bind, insulin molecules circulating in the bloodstream. This interaction between insulin and its receptor prompts the biochemical signals that enable the cells to absorb glucose from the blood and use it for energy.\n \nProblems in cell signaling systems can set off a chain reaction that leads to diabetes or other diseases. Many studies have focused on how insulin signals cells to communicate and regulate action. Researchers have identified proteins and pathways that transmit the insulin signal and have mapped interactions between insulin and body tissues, including the way insulin helps the liver control blood glucose levels. Researchers have also found that key signals also come from fat cells, which produce substances that cause inflammation and insulin resistance.\n \nThis work holds the key to combating insulin resistance and diabetes. As scientists learn more about cell signaling systems involved in glucose regulation, they will have more opportunities to develop effective treatments.\n \nBeta Cell Dysfunction\n \nScientists think beta cell dysfunction is a key contributor to type 2 diabetes. Beta cell impairment can cause inadequate or abnormal patterns of insulin release. Also, beta cells may be damaged by high blood glucose itself, a condition called glucose toxicity.\n \nScientists have not determined the causes of beta cell dysfunction in most cases. Single gene defects lead to specific forms of diabetes called maturity-onset diabetes of the young (MODY). The genes involved regulate insulin production in the beta cells. Although these forms of diabetes are rare, they provide clues as to how beta cell function may be affected by key regulatory factors. Other gene variants are involved in determining the number and function of beta cells. But these variants account for only a small percentage of type 2 diabetes cases. Malnutrition early in life is also being investigated as a cause of beta cell dysfunction. The metabolic environment of the developing fetus may also create a predisposition for diabetes later in life.\n \nRisk Factors for Type 2 Diabetes\n \nPeople who develop type 2 diabetes are more likely to have the following characteristics:\n \n- age 45 or older - overweight or obese - physically inactive - parent or sibling with diabetes - family background that is African American, Alaska Native, American Indian, Asian American, Hispanic\/Latino, or Pacific Islander American - history of giving birth to a baby weighing more than 9 pounds - history of gestational diabetes - high blood pressure140\/90 or aboveor being treated for high blood pressure - high-density lipoprotein (HDL), or good, cholesterol below 35 milligrams per deciliter (mg\/dL), or a triglyceride level above 250 mg\/dL - polycystic ovary syndrome, also called PCOS - prediabetesan A1C level of 5.7 to 6.4 percent; a fasting plasma glucose test result of 100125 mg\/dL, called impaired fasting glucose; or a 2-hour oral glucose tolerance test result of 140199, called impaired glucose tolerance - acanthosis nigricans, a condition associated with insulin resistance, characterized by a dark, velvety rash around the neck or armpits - history of CVD\n \nThe American Diabetes Association (ADA) recommends that testing to detect prediabetes and type 2 diabetes be considered in adults who are overweight or obese and have one or more additional risk factors for diabetes. In adults without these risk factors, testing should begin at age 45."} {"_id":"d00201bf-f405-47b8-a8fb-eeb57c0deb48","text":"Insulin Resistance and Beta Cell Dysfunction\n \nHormones produced by the placenta and other pregnancy-related factors contribute to insulin resistance, which occurs in all women during late pregnancy. Insulin resistance increases the amount of insulin needed to control blood glucose levels. If the pancreas cant produce enough insulin due to beta cell dysfunction, gestational diabetes occurs.\n \nAs with type 2 diabetes, excess weight is linked to gestational diabetes. Overweight or obese women are at particularly high risk for gestational diabetes because they start pregnancy with a higher need for insulin due to insulin resistance. Excessive weight gain during pregnancy may also increase risk.\n \nFamily History\n \nHaving a family history of diabetes is also a risk factor for gestational diabetes, suggesting that genes play a role in its development. Genetics may also explain why the disorder occurs more frequently in African Americans, American Indians, and Hispanics\/Latinos. Many gene variants or combinations of variants may increase a womans risk for developing gestational diabetes. Studies have found several gene variants associated with gestational diabetes, but these variants account for only a small fraction of women with gestational diabetes.\n \nFuture Risk of Type 2 Diabetes\n \nBecause a womans hormones usually return to normal levels soon after giving birth, gestational diabetes disappears in most women after delivery. However, women who have gestational diabetes are more likely to develop gestational diabetes with future pregnancies and develop type 2 diabetes.3 Women with gestational diabetes should be tested for persistent diabetes 6 to 12 weeks after delivery and at least every 3 years thereafter.\n \nAlso, exposure to high glucose levels during gestation increases a childs risk for becoming overweight or obese and for developing type 2 diabetes later on. The result may be a cycle of diabetes affecting multiple generations in a family.

Cushings syndrome and acromegaly are examples of hormonal disorders that can cause prediabetes and diabetes by inducing insulin resistance. Cushings syndrome is marked by excessive production of cortisolsometimes called the stress hormone. Acromegaly occurs when the body produces too much growth hormone.

Although a person does not control kidney function, a person does control when the bladder empties. Bladder emptying is known as urination. The bladder stores urine until the person finds an appropriate time and place to urinate. A normal bladder acts like a reservoir and can hold 1.5 to 2 cups of urine. How often a person needs to urinate depends on how quickly the kidneys produce the urine that fills the bladder. The muscles of the bladder wall remain relaxed while the bladder fills with urine. As the bladder fills to capacity, signals sent to the brain tell a person to find a toilet soon.

The urethral stricture often gets better a few weeks after surgery.\n \nUrethral stricture and acute or chronic urinary retention may occur when the muscles surrounding the urethra do not relax. This condition happens mostly in women.\n \nUrinary tract stones. Urinary tract stones develop from crystals that form in the urine and build up on the inner surfaces of the kidneys, ureters, or bladder. The stones formed or lodged in the bladder may block the opening to the urethra.\n \nCystocele. A cystocele is a bulging of the bladder into the vagina. A cystocele occurs when the muscles and supportive tissues between a womans bladder and vagina weaken and stretch, letting the bladder sag from its normal position and bulge into the vagina. The abnormal position of the bladder may cause it to press against and pinch the urethra.\n \nMore information is provided in the NIDDK health topic, Cystocele.\n \nRectocele. A rectocele is a bulging of the rectum into the vagina. A rectocele occurs when the muscles and supportive tissues between a womans rectum and vagina weaken and stretch, letting the rectum sag from its normal position and bulge into the vagina. The abnormal position of the rectum may cause it to press against and pinch the urethra.\n \nConstipation. Constipation is a condition in which a person has fewer than three bowel movements a week or has bowel movements with stools that are hard, dry, and small, making them painful or difficult to pass. A person with constipation may feel bloated or have pain in the abdomen the area between the chest and hips. Some people with constipation often have to strain to have a bowel movement. Hard stools in the rectum may push against the bladder and urethra, causing the urethra to be pinched, especially if a rectocele is present.\n \nMore information is provided in the NIDDK health topic, Constipation.\n \nTumors and cancers. Tumors and cancerous tissues in the bladder or urethra can gradually expand and obstruct urine flow by pressing against and pinching the urethra or by blocking the bladder outlet. Tumors may be cancerous or noncancerous.\n \nNerve Problems\n \nUrinary retention can result from problems with the nerves that control the bladder and sphincters. Many events or conditions can interfere with nerve signals between the brain and the bladder and sphincters. If the nerves are damaged, the brain may not get the signal that the bladder is full. Even when a person has a full bladder, the bladder muscles that squeeze urine out may not get the signal to push, or the sphincters may not get the signal to relax. People of all ages can have nerve problems that interfere with bladder function. Some of the most common causes of nerve problems include\n \n- vaginal childbirth - brain or spinal cord infections or injuries - diabetes - stroke - multiple sclerosis - pelvic injury or trauma - heavy metal poisoning\n \nIn addition, some children are born with defects that affect the coordination of nerve signals among the bladder, spinal cord, and brain. Spina bifida and other birth defects that affect the spinal cord can lead to urinary retention in newborns.\n \nMore information is provided in the NIDDK health topics, Nerve Disease and Bladder Control and Urine Blockage in Newborns.\n \nMany patients have urinary retention right after surgery. During surgery, anesthesia is often used to block pain signals in the nerves, and fluid is given intravenously to compensate for possible blood loss. The combination of anesthesia and intravenous (IV) fluid may result in a full bladder with impaired nerve function, causing urinary retention. Normal bladder nerve function usually returns once anesthesia wears off. The patient will then be able to empty the bladder completely.\n \nMedications\n \nVarious classes of medications can cause urinary retention by interfering with nerve signals to the bladder and prostate. These medications include\n \n- antihistamines to treat allergies - cetirizine (Zyrtec) - chlorpheniramine (Chlor-Trimeton) - diphenhydramine (Benadryl) - fexofenadine (Allegra) - anticholinergics\/antispasmodics to treat stomach cramps, muscle spasms, and urinary incontinence - hyoscyamine (Levbid) - oxybutynin (Ditropan) - propantheline (Pro-Banthine) - tolterodine (Detrol) - tricyclic antidepressants to treat anxiety and depression - amitriptyline (Elavil) - doxepin (Adapin) - imipramine (Tofranil) - nortriptyline (Pamelor)\n \nOther medications associated with urinary retention include\n \n- decongestants - ephedrine - phenylephrine - pseudoephedrine - nifedipine (Procardia), a medication to treat high blood pressure and chest pain - carbamazepine (Tegretol), a medication to control seizures in people with epilepsy - cyclobenzaprine (Flexeril), a muscle relaxant medication - diazepam (Valium), a medication used to relieve anxiety, muscle spasms, and seizures - nonsteroidal anti-inflammatory drugs - amphetamines - opioid analgesics\n \nOver-the-counter cold and allergy medications that contain decongestants, such as pseudoephedrine, and antihistamines, such as diphenhydramine, can increase symptoms of urinary retention in men with prostate enlargement.\n \nWeakened Bladder Muscles\n \nAging is a common cause of weakened bladder muscles. Weakened bladder muscles may not contract strongly enough or long enough to empty the bladder completely, resulting in urinary retention."} {"_id":"1423f97a-781e-49bc-8128-b105a49c9d1c","text":"Urinary retention in men becomes more common with age.\n \n- In men 40 to 83 years old, the overall incidence of urinary retention is 4.5 to 6.8 per 1,000 men.2 - For men in their 70s, the overall incidence increases to 100 per 1,000 men.2 - For men in their 80s, the incidence of acute urinary retention is 300 per 1,000 men.2\n \nUrinary retention in women is less common, though not rare.3 The incidence of urinary retention in women has not been well studied because researchers have primarily thought of urinary retention as a mans problem related to the prostate.4"} {"_id":"690218cb-cca4-49b6-8a03-5c64ab49b794","text":"The symptoms of acute urinary retention may include the following and require immediate medical attention:\n \n- inability to urinate - painful, urgent need to urinate - pain or discomfort in the lower abdomen - bloating of the lower abdomen\n \nThe symptoms of chronic urinary retention may include\n \n- urinary frequencyurination eight or more times a day - trouble beginning a urine stream - a weak or an interrupted urine stream - an urgent need to urinate with little success when trying to urinate - feeling the need to urinate after finishing urination - mild and constant discomfort in the lower abdomen and urinary tract\n \nSome people with chronic urinary retention may not have symptoms that lead them to seek medical care.

The health care provider may be able to feel a distended bladder by lightly tapping on the lower belly.\n \nPostvoid Residual Measurement\n \nThis test measures the amount of urine left in the bladder after urination. The remaining urine is called the postvoid residual. A specially trained technician performs an ultrasound, which uses harmless sound waves to create a picture of the bladder, to measure the postvoid residual. The technician performs the bladder ultrasound in a health care providers office, a radiology center, or a hospital, and a radiologista doctor who specializes in medical imaginginterprets the images. The patient does not need anesthesia.\n \nA health care provider may use a cathetera thin, flexible tubeto measure postvoid residual. The health care provider inserts the catheter through the urethra into the bladder, a procedure called catheterization, to drain and measure the amount of remaining urine. A postvoid residual of 100 mL or more indicates the bladder does not empty completely. A health care provider performs this test during an office visit. The patient often receives local anesthesia.\n \nMedical Tests\n \nCystoscopy. Cystoscopy is a procedure that requires a tubelike instrument, called a cystoscope, to look inside the urethra and bladder. A health care provider performs cystoscopy during an office visit or in an outpatient center or a hospital. The patient will receive local anesthesia. However, in some cases, the patient may receive sedation and regional or general anesthesia. A health care provider may use cystoscopy to diagnose urethral stricture or look for a bladder stone blocking the opening of the urethra.\n \nMore information is provided in the NIDDK health topic, Cystoscopy and Ureteroscopy.\n \nCT scans. CT scans use a combination of x rays and computer technology to create images. For a CT scan, a health care provider may give the patient a solution to drink and an injection of a special dye, called contrast medium. CT scans require the patient to lie on a table that slides into a tunnel-shaped device where a technician takes the x rays. An x-ray technician performs the procedure in an outpatient center or a hospital, and a radiologist interprets the images. The patient does not need anesthesia. A health care provider may give infants and children a sedative to help them fall asleep for the test. CT scans can show\n \n- urinary tract stones - UTIs - tumors - traumatic injuries - abnormal, fluid-containing sacs called cysts\n \nUrodynamic tests. Urodynamic tests include a variety of procedures that look at how well the bladder and urethra store and release urine. A health care provider may use one or more urodynamic tests to diagnose urinary retention. The health care provider will perform these tests during an office visit. For tests that use a catheter, the patient often receives local anesthesia.\n \n- Uroflowmetry. Uroflowmetry measures urine speed and volume. Special equipment automatically measures the amount of urine and the flow ratehow fast urine comes out. Uroflowmetry equipment includes a device for catching and measuring urine and a computer to record the data. The equipment creates a graph that shows changes in flow rate from second to second so the health care provider can see the highest flow rate and how many seconds it takes to get there. A weak bladder muscle or blocked urine flow will yield an abnormal test result. - Pressure flow study. A pressure flow study measures the bladder pressure required to urinate and the flow rate a given pressure generates. A health care provider places a catheter with a manometer into the bladder. The manometer measures bladder pressure and flow rate as the bladder empties. A pressure flow study helps diagnose bladder outlet obstruction. - Video urodynamics. This test uses x rays or ultrasound to create real-time images of the bladder and urethra during the filling or emptying of the bladder. For x rays, a health care provider passes a catheter through the urethra into the bladder. He or she fills the bladder with contrast medium, which is visible on the video images. Video urodynamic images can show the size and shape of the urinary tract, the flow of urine, and causes of urinary retention, such as bladder neck obstruction.\n \nMore information is provided in the NIDDK health topic, Urodynamic Testing.\n \nElectromyography. Electromyography uses special sensors to measure the electrical activity of the muscles and nerves in and around the bladder and sphincters. A specially trained technician places sensors on the skin near the urethra and rectum or on a urethral or rectal catheter. The sensors record, on a machine, muscle and nerve activity. The patterns of the nerve impulses show whether the messages sent to the bladder and sphincters coordinate correctly. A technician performs electromyography in a health care providers office, an outpatient center, or a hospital. The patient does not need anesthesia if the technician uses sensors placed on the skin. The patient will receive local anesthesia if the technician uses sensors placed on a urethral or rectal catheter."} {"_id":"4f116789-1a05-487b-8124-e8ea8a838088","text":"A health care provider treats urinary retention with\n \n- bladder drainage - urethral dilation - urethral stents - prostate medications - surgery\n \nThe type and length of treatment depend on the type and cause of urinary retention.\n \nBladder Drainage\n \nBladder drainage involves catheterization to drain urine. Treatment of acute urinary retention begins with catheterization to relieve the immediate distress of a full bladder and prevent bladder damage. A health care provider performs catheterization during an office visit or in an outpatient center or a hospital. The patient often receives local anesthesia. The health care provider can pass a catheter through the urethra into the bladder. In cases of a blocked urethra, he or she can pass a catheter directly through the lower abdomen, just above the pubic bone, directly into the bladder. In these cases, the health care provider will use anesthesia.\n \nFor chronic urinary retention, the patient may require intermittentoccasional, or not continuousor long-term catheterization if other treatments do not work. Patients who need to continue intermittent catheterization will receive instruction regarding how to selfcatheterize to drain urine as necessary.\n \nUrethral Dilation\n \nUrethral dilation treats urethral stricture by inserting increasingly wider tubes into the urethra to widen the stricture. An alternative dilation method involves inflating a small balloon at the end of a catheter inside the urethra. A health care provider performs a urethral dilation during an office visit or in an outpatient center or a hospital. The patient will receive local anesthesia. In some cases, the patient will receive sedation and regional anesthesia.\n \nUrethral Stents\n \nAnother treatment for urethral stricture involves inserting an artificial tube, called a stent, into the urethra to the area of the stricture. Once in place, the stent expands like a spring and pushes back the surrounding tissue, widening the urethra. Stents may be temporary or permanent. A health care provider performs stent placement during an office visit or in an outpatient center or a hospital. The patient will receive local anesthesia. In some cases, the patient will receive sedation and regional anesthesia.\n \nProstate Medications\n \nMedications that stop the growth of or shrink the prostate or relieve urinary retention symptoms associated with benign prostatic hyperplasia include\n \n- dutasteride (Avodart) - finasteride (Proscar)\n \nThe following medications relax the muscles of the bladder outlet and prostate to help relieve blockage:\n \n- alfuzosin (Uroxatral) - doxazosin (Cardura) - silodosin (Rapaflo) - tadalafil (Cialis) - tamsulosin (Flomax) - terazosin (Hytrin)\n \nSurgery\n \nProstate surgery. To treat urinary retention caused by benign prostatic hyperplasia, a urologista doctor who specializes in the urinary tractmay surgically destroy or remove enlarged prostate tissue by using the transurethral method. For transurethral surgery, the urologist inserts a catheter or surgical instruments through the urethra to reach the prostate. Removal of the enlarged tissue usually relieves the blockage and urinary retention caused by benign prostatic hyperplasia. A urologist performs some procedures on an outpatient basis. Some men may require a hospital stay. In some cases, the urologist will remove the entire prostate using open surgery. Men will receive general anesthesia and have a longer hospital stay than for other surgical procedures. Men will also have a longer rehabilitation period for open surgery.\n \nMore information is provided in the NIDDK health topic, Prostate Enlargement: Benign Prostatic Hyperplasia.\n \nInternal urethrotomy. A urologist can repair a urethral stricture by performing an internal urethrotomy. For this procedure, the urologist inserts a special catheter into the urethra until it reaches the stricture. The urologist then uses a knife or laser to make an incision that opens the stricture. The urologist performs an internal urethrotomy in an outpatient center or a hospital. The patient will receive general anesthesia.\n \nCystocele or rectocele repair. Women may need surgery to lift a fallen bladder or rectum into its normal position. The most common procedure for cystocele and rectocele repair involves a urologist, who also specializes in the female reproductive system, making an incision in the wall of the vagina. Through the incision, the urologist looks for a defect or hole in the tissue that normally separates the vagina from the other pelvic organs. The urologist places stitches in the tissue to close up the defect and then closes the incision in the vaginal wall with more stitches, removing any extra tissue. These stitches tighten the layers of tissue that separate the organs, creating more support for the pelvic organs. A urologist or gynecologista doctor who specializes in the female reproductive systemperforms the surgery to repair a cystocele or rectocele in a hospital. Women will receive anesthesia.\n \nTumor and cancer surgery.

Urine is normally sterile, and the normal flow of urine usually prevents bacteria from infecting the urinary tract. With urinary retention, the abnormal urine flow gives bacteria at the opening of the urethra a chance to infect the urinary tract.\n \nBladder damage. If the bladder becomes stretched too far or for long periods, the muscles may be permanently damaged and lose their ability to contract.\n \nKidney damage. In some people, urinary retention causes urine to flow backward into the kidneys. This backward flow, called reflux, may damage or scar the kidneys.\n \nUrinary incontinence after prostate, tumor, or cancer surgery. Transurethral surgery to treat benign prostatic hyperplasia may result in urinary incontinence in some men. This problem is often temporary.

Proteins in the blood also perform a number of important functions. They protect the body from infection, help blood clot, and keep the right amount of fluid circulating throughout the body.\n \nAs blood passes through healthy kidneys, they filter out the waste products and leave in the things the body needs, like albumin and other proteins. Most proteins are too big to pass through the kidneys' filters into the urine. However, proteins from the blood can leak into the urine when the filters of the kidney, called glomeruli, are damaged.\n \nProteinuria is a sign of chronic kidney disease (CKD), which can result from diabetes, high blood pressure, and diseases that cause inflammation in the kidneys. For this reason, testing for albumin in the urine is part of a routine medical assessment for everyone. Kidney disease is sometimes called renal disease.

Genes provide instructions for making proteins in the body. A gene mutation is a permanent change in the DNA sequence that makes up a gene. DNA, or deoxyribonucleic acid, is the material inside cells that carries genetic information and passes genes from parent to child. Approximately 30 to 50 percent of people with Alagille syndrome have an inherited gene mutation, meaning it has been passed on by a parent. In the remaining cases, the gene mutation develops spontaneously.1 In spontaneous cases, neither parent carries a copy of the mutated gene.\n \nMost cases of Alagille syndrome are caused by a mutation in the JAGGED1 (JAG1) gene. In less than 1 percent of cases, a mutation in the NOTCH2 gene is the cause.2\n \n\n \nGenetic Disorders Each cell contains thousands of genes that provide the instructions for making proteins for growth and repair of the body. If a gene has a mutation, the protein made by that gene may not function properly, which sometimes creates a genetic disorder. Not all gene mutations cause a disorder. People have two copies of most genes; one copy is inherited from each parent. A genetic disorder occurs when one or both parents pass a mutated gene to a child at conception. A genetic disorder can also occur through a spontaneous gene mutation, meaning neither parent carries a copy of the mutated gene. Once a spontaneous gene mutation has occurred in a person, it can be passed to the person's children.

These signs and symptoms can occur in children and adults with Alagille syndrome, and in infants as early as the first 3 months of life.\n \nJaundice. Jaundicewhen the skin and whites of the eyes turn yellowis a result of the liver not removing bilirubin from the blood. Bilirubin is a reddish-yellow substance formed when hemoglobin breaks down. Hemoglobin is an iron-rich protein that gives blood its red color. Bilirubin is absorbed by the liver, processed, and released into bile. Blockage of the bile ducts forces bilirubin and other elements of bile to build up in the blood.\n \nJaundice may be difficult for parents and even health care providers to detect. Many healthy newborns have mild jaundice during the first 1 to 2 weeks of life due to an immature liver. This normal type of jaundice disappears by the second or third week of life, whereas the jaundice of Alagille syndrome deepens. Newborns with jaundice after 2 weeks of life should be seen by a health care provider to check for a possible liver problem.\n \nDark urine and gray or white stools. High levels of bilirubin in the blood that pass into the urine can make the urine darker, while stool lightens from a lack of bilirubin reaching the intestines. Gray or white bowel movements after 2 weeks of age are a reliable sign of a liver problem and should prompt a visit to a health care provider.\n \nPruritus. The buildup of bilirubin in the blood may cause itching, also called pruritus. Pruritus usually starts after 3 months of age and can be severe.\n \nXanthomas. Xanthomas are fatty deposits that appear as yellow bumps on the skin. They are caused by abnormally high cholesterol levels in the blood, common in people with liver disease. Xanthomas may appear anywhere on the body. However, xanthomas are usually found on the elbows, joints, tendons, knees, hands, feet, or buttocks.\n \nOther Signs and Symptoms of Alagille Syndrome\n \nCertain signs of Alagille syndrome are unique to the disorder, including those that affect the vertebrae and facial features.\n \nFace. Many children with Alagille syndrome have deep-set eyes, a straight nose, a small and pointed chin, large ears, and a prominent, wide forehead. These features are not usually recognized until after infancy. By adulthood, the chin is more prominent.\n \nEyes. Posterior embryotoxon is a condition in which an opaque ring is present in the cornea, the transparent covering of the eyeball. The abnormality is common in people with Alagille syndrome, though it usually does not affect vision.\n \nSkeleton. The most common skeletal defect in a person with Alagille syndrome is when the shape of the vertebraebones of the spinegives the appearance of flying butterflies. This defect, known as \"butterfly\" vertebrae, rarely causes medical problems or requires treatment.\n \nHeart and blood vessels. People with Alagille syndrome may have the following signs and symptoms having to do with the heart and blood vessels:\n \n- heart murmuran extra or unusual sound heard during a heartbeat. A heart murmur is the most common sign of Alagille syndrome other than the general symptoms of liver disease.1 Most people with Alagille syndrome have a narrowing of the blood vessels that carry blood from the heart to the lungs.1 This narrowing causes a murmur that can be heard with a stethoscope. Heart murmurs usually do not cause problems. - heart walls and valve problems. A small number of people with Alagille syndrome have serious problems with the walls or valves of the heart. These conditions may need treatment with medications or corrective surgery. - blood vessel problems. People with Alagille syndrome may have abnormalities of the blood vessels in the head and neck. This serious complication can lead to internal bleeding or stroke. Alagille syndrome can also cause narrowing or bulging of other blood vessels in the body.\n \nKidney disease. A wide range of kidney diseases can occur in Alagille syndrome. The kidneys are two bean-shaped organs, each about the size of a fist, that filter wastes and extra fluid from the blood. Some people have small kidneys or have cystsfluid-filled sacsin the kidneys. Kidney function can also decrease."} {"_id":"08eff129-5d0a-47ee-b3c3-f6ad9c806380","text":"The complications of Alagille syndrome include liver failure, portal hypertension, and growth problems. People with Alagille syndrome usually have a combination of complications, and may not have every complication listed below.\n \nLiver failure. Over time, the decreased number of bile ducts may lead to chronic liver failure, also called end-stage liver disease. This condition progresses over months, years, or even decades. The liver can no longer perform important functions or effectively replace damaged cells. A person may need a liver transplant. A liver transplant is surgery to remove a diseased or an injured liver and replace it with a healthy whole liver or a segment of a liver from another person, called a donor.\n \nPortal hypertension. The spleen is the organ that cleans blood and makes white blood cells. White blood cells attack bacteria and other foreign cells. Blood flow from the spleen drains directly into the liver. When a person with Alagille syndrome has advanced liver disease, the blood flow backs up into the spleen and other blood vessels. This condition is called portal hypertension. The spleen may become larger in the later stages of liver disease. A person with an enlarged spleen should avoid contact sports to protect the organ from injury. Advanced portal hypertension can lead to serious bleeding problems.\n \nGrowth problems. Alagille syndrome can lead to poor growth in infants and children, as well as delayed puberty in older children. Liver disease can cause malabsorption, which can result in growth problems. Malabsorption is the inability of the small intestine to absorb nutrients from foods, which results in protein, calorie, and vitamin deficiencies. Serious heart problems, if present in Alagille syndrome, can also affect growth.\n \nMalabsorption. People with Alagille syndrome may have diarrhealoose, watery stoolsdue to malabsorption. The condition occurs because bile is necessary for the digestion of food. Malabsorption can lead to bone fractures, eye problems, blood-clotting problems, and learning delays.\n \nLong-term Outlook\n \nThe long-term outlook for people with Alagille syndrome depends on several factors, including the severity of liver damage and heart problems. Predicting who will experience improved bile flow and who will progress to chronic liver failure is difficult. Ten to 30 percent of people with Alagille syndrome will eventually need a liver transplant.3\n \nMany adults with Alagille syndrome whose symptoms improve with treatment lead normal, productive lives. Deaths in people with Alagille syndrome are most often caused by chronic liver failure, heart problems, and blood vessel problems."} {"_id":"fa7f5524-83f0-43a4-8ceb-b4f31370cf2e","text":"A health care provider diagnoses Alagille syndrome by performing a thorough physical exam and ordering one or more of the following tests and exams:\n \n- blood test - urinalysis - x ray - abdominal ultrasound - cardiology exam - slit-lamp exam - liver biopsy - genetic testing\n \nAlagille syndrome can be difficult to diagnose because the signs and symptoms vary and the syndrome is so rare.\n \nFor a diagnosis of Alagille syndrome, three of the following symptoms typically should be present:\n \n- liver symptoms, such as jaundice, pruritus, malabsorption, and xanthomas - heart abnormalities or murmurs - skeletal abnormalities - posterior embryotoxon - facial features typical of Alagille syndrome - kidney disease - blood vessel problems\n \nA health care provider may perform a liver biopsy to diagnose Alagille syndrome; however, it is not necessary to make a diagnosis. A diagnosis can be made in a person who does not meet the clinical criteria of Alagille syndrome yet does have a gene mutation of JAG1. The health care provider may have a blood sample tested to look for the JAG1 gene mutation. The gene mutation can be identified in 94 percent of people with a diagnosis of Alagille syndrome.2\n \nBlood test. A blood test involves drawing blood at a health care provider's office or a commercial facility and sending the sample to a lab for analysis. The blood test can show nutritional status and the presence of liver disease and kidney function.\n \nUrinalysis. Urinalysis is the testing of a urine sample. The urine sample is collected in a special container in a health care provider's office or a commercial facility and can be tested in the same location or sent to a lab for analysis. Urinalysis can show many problems of the urinary tract and other body systems. The sample may be observed for color, cloudiness, or concentration; signs of drug use; chemical composition, including glucose; the presence of protein, blood cells, or bacteria; or other signs of disease.\n \nX ray. An x ray is a picture created by using radiation and recorded on film or on a computer. The amount of radiation used is small. An x-ray technician performs the x ray at a hospital or an outpatient center, and a radiologista doctor who specializes in medical imaginginterprets the images. Anesthesia is not needed. The patient will lie on a table or stand during the x ray. The technician positions the x-ray machine over the spine area to look for \"butterfly\" vertebrae. The patient will hold his or her breath as the picture is taken so that the picture will not be blurry. The patient may be asked to change position for additional pictures.\n \nAbdominal ultrasound. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. The transducer can be moved to different angles to make it possible to examine different organs. In abdominal ultrasound, the health care provider applies a gel to the patient's abdomen and moves a handheld transducer over the skin. The gel allows the transducer to glide easily, and it improves the transmission of the signals. A specially trained technician performs the procedure in a health care provider's office, an outpatient center, or a hospital, and a radiologist interprets the images; anesthesia is not needed. The images can show an enlarged liver or rule out other conditions.\n \nCardiology exam. A cardiologista doctor who treats people who have heart problemsperforms a cardiology exam in a health care provider's office, an outpatient center, or a hospital. During a full exam, a cardiologist may inspect the patient's physical appearance, measure pulse rate and blood pressure, observe the jugular vein, check for rapid or skipped heartbeats, listen for variations in heart sounds, and listen to the lungs.\n \nSlit-lamp exam. An ophthalmologista doctor who diagnoses and treats all eye diseases and eye disordersperforms a slit-lamp exam to diagnose posterior embryotoxon. The ophthalmologist examines the eye with a slit lamp, a microscope combined with a high-intensity light that shines a thin beam on the eye. While sitting in a chair, the patient will rest his or her head on the slit lamp. A yellow dye may be used to examine the cornea and tear layer. The dye is applied as a drop, or the specialist may touch a strip of paper stained with the dye to the white of the patient's eye. The specialist will also use drops in the patient's eye to dilate the pupil.\n \nLiver biopsy. A liver biopsy is a procedure that involves taking a piece of liver tissue for examination with a microscope for signs of damage or disease. The health care provider may ask the patient to stop taking certain medications temporarily before the liver biopsy. The patient may be asked to fast for 8 hours before the procedure.\n \nDuring the procedure, the patient lies on a table, right hand resting above the head. A local anesthetic is applied to the area where the biopsy needle will be inserted. If needed, sedatives and pain medication are also given. The health care provider uses a needle to take a small piece of liver tissue. The health care provider may use ultrasound, computerized tomography scans, or other imaging techniques to guide the needle. After the biopsy, the patient should lie on the right side for up to 2 hours and is monitored an additional 2 to 4 hours before being sent home.\n \nGenetic testing. The health care provider may refer a person suspected of having Alagille syndrome to a geneticista doctor who specializes in genetic disorders. For a genetic test, the geneticist takes a blood or saliva sample and analyzes the DNA for the JAG1 gene mutation. The geneticist tests for the JAG1 gene mutation first, since it is more common in Alagille syndrome than NOTCH2. Genetic testing is often done only by specialized labs. The results may not be available for several months because of the complexity of the testing.\n \nThe usefulness of genetic testing for Alagille syndrome is limited by two factors:\n \n- Detection of a mutated gene cannot predict the onset of symptoms or how serious the disorder will be. - Even if a mutated gene is found, no specific cure for the disorder exists.\n \n\n \nWhen to Consider Genetic Counseling People who are considering genetic testing may want to consult a genetics counselor. Genetic counseling can help family members understand how test results may affect them individually and as a family. Genetic counseling is provided by genetics professionalshealth care professionals with specialized degrees and experience in medical genetics and counseling. Genetics professionals include geneticists, genetics counselors, and genetics nurses. Genetics professionals work as members of health care teams, providing information and support to individuals or families who have genetic disorders or a higher chance of having an inherited condition. Genetics professionals - assess the likelihood of a genetic disorder by researching a family's history, evaluating medical records, and conducting a physical exam of the patient and other family members - weigh the medical, social, and ethical decisions surrounding genetic testing - provide support and information to help a person make a decision about testing - interpret the results of genetic tests and medical data - provide counseling or refer individuals and families to support services - serve as patient advocates - explain possible treatments or preventive measures - discuss reproductive options Genetic counseling may be useful when a family member is deciding whether to have genetic testing and again later when test results are available."} {"_id":"57ba372d-c72b-4110-91cc-98769a9d49a1","text":"Treatment for Alagille syndrome includes medications and therapies that increase the flow of bile from the liver, promote growth and development in infants' and children's bodies, correct nutritional deficiencies, and reduce the person's discomfort. Ursodiol (Actigall, Urso) is a medication that increases bile flow. Other treatments address specific symptoms of the disorder.\n \nLiver failure. People with Alagille syndrome who develop end-stage liver failure need a liver transplant with a whole liver from a deceased donor or a segment of a liver from a living donor. People with Alagille syndrome who also have heart problems may not be candidates for a transplant because they could be more likely to have complications during and after the procedure. A liver transplant surgical team performs the transplant in a hospital.\n \nMore information is provided in the NIDDK health topic, Liver Transplantation.\n \nPruritus. Itching may decrease when the flow of bile from the liver is increased. Medications such as cholestyramine (Prevalite), rifampin (Rifadin, Rimactane), naltrexone (Vivitrol), or antihistamines may be prescribed to relieve pruritus. People should hydrate their skin with moisturizers and keep their fingernails trimmed to prevent skin damage from scratching. People with Alagille syndrome should avoid baths and take short showers to prevent the skin from drying out.\n \nIf severe pruritus does not improve with medication, a procedure called partial external biliary diversion may provide relief from itching. The procedure involves surgery to connect one end of the small intestine to the gallbladder and the other end to an opening in the abdomencalled a stomathrough which bile leaves the body and is collected in a pouch. A surgeon performs partial external biliary diversion in a hospital. The patient will need general anesthesia.\n \nMalabsorption and growth problems. Infants with Alagille syndrome are given a special formula that helps the small intestine absorb much-needed fat. Infants, children, and adults can benefit from a high-calorie diet, calcium, and vitamins A, D, E, and K. They may also need additional zinc. If someone with Alagille syndrome does not tolerate oral doses of vitamins, a health care provider may give the person injections for a period of time. A child may receive additional calories through a tiny tube that is passed through the nose into the stomach. If extra calories are needed for a long time, a health care provider may place a tube, called a gastrostomy tube, directly into the stomach through a small opening made in the abdomen. A child's growth may improve with increased nutrition and flow of bile from the liver.\n \nXanthomas. For someone who has Alagille syndrome, these fatty deposits typically worsen over the first few years of life and then improve over time.

In most such cases, however, the parathyroid glands function normally.\n \nThe parathyroid glands are part of the bodys endocrine system. Endocrine glands produce, store, and release hormones, which travel in the bloodstream to target cells elsewhere in the body and direct the cells activity.\n \nThough their names are similar, the thyroid and parathyroid glands are entirely different glands, each producing distinct hormones with specific functions. The parathyroid glands produce PTH, a hormone that helps maintain the correct balance of calcium in the body. PTH regulates the level of calcium in the blood, release of calcium from bone, absorption of calcium in the small intestine, and excretion of calcium in the urine.\n \nWhen the level of calcium in the blood falls too low, normal parathyroid glands release just enough PTH to restore the blood calcium level."} {"_id":"9ff06cc5-883e-4708-a35f-80fe4add3be2","text":"High PTH levels trigger the bones to release increased amounts of calcium into the blood, causing blood calcium levels to rise above normal.

In patients without any symptoms, guidelines are used to identify who might benefit from parathyroid surgery.3\n \nWhen performed by experienced endocrine surgeons, surgery cures primary hyperparathyroidism in more than 95 percent of operations.2\n \nSurgeons often use imaging tests before surgery to locate the overactive gland to be removed. The most commonly used tests are sestamibi and ultrasound scans. In a sestamibi scan, the patient receives an injection of a small amount of radioactive dye that is absorbed by overactive parathyroid glands. The overactive glands can then be viewed using a special camera.\n \nSurgeons use two main strategies to remove the overactive gland or glands:\n \n- Minimally invasive parathyroidectomy. This type of surgery, which can be done on an outpatient basis, may be used when only one of the parathyroid glands is likely to be overactive. Guided by a tumor-imaging test, the surgeon makes a small incision in the neck to remove the gland. The small incision means that patients typically have less pain and a quicker recovery than with more invasive surgery. Local or general anesthesia may be used for this type of surgery. - Standard neck exploration. This type of surgery involves a larger incision that allows the surgeon to access and examine all four parathyroid glands and remove the overactive ones. This type of surgery is more extensive and typically requires a hospital stay of 1 to 2 days. Surgeons use this approach if they plan to inspect more than one gland. General anesthesia is used for this type of surgery.\n \nAlmost all people with primary hyperparathyroidism who have symptoms can benefit from surgery. Experts believe that those without symptoms but who meet guidelines for surgery will also benefit from surgery. Surgery can lead to improved bone density and fewer fractures and can reduce the chance of forming kidney stones. Other potential benefits are being studied by researchers.\n \nSurgery for primary hyperparathyroidism has a complication rate of 13 percent when performed by experienced endocrine surgeons.4 Rarely, patients undergoing surgery experience damage to the nerves controlling the vocal cords, which can affect speech. A small number of patients lose all their healthy parathyroid tissue and thus develop chronic low calcium levels, requiring lifelong treatment with calcium and some form of vitamin D. This complication is called hypoparathyroidism. The complication rate is slightly higher for operations on multiple tumors than for a single adenoma because more extensive surgery is needed.\n \nPeople with primary hyperparathyroidism due to familial hypocalciuric hypercalcemia should not have surgery.\n \nMonitoring\n \nSome people who have mild primary hyperparathyroidism may not need immediate or even any surgery and can be safely monitored. People may wish to talk with their health care provider about long-term monitoring if they\n \n- are symptom-free - have only slightly elevated blood calcium levels - have normal kidneys and bone density\n \nLong-term monitoring should include periodic clinical evaluations, annual serum calcium measurements, annual serum creatinine measurements to check kidney function, and bone density measurements every 1 to 2 years.\n \nVitamin D deficiency should be corrected if present. Patients who are monitored need not restrict calcium in their diets.\n \nIf the patient and health care provider choose long-term monitoring, the patient should\n \n- drink plenty of water - exercise regularly - avoid certain diuretics, such as thiazides\n \nEither immobilizationthe inability to move due to illness or injuryor gastrointestinal illness with vomiting or diarrhea that leads to dehydration can cause blood calcium levels to rise further in someone with primary hyperparathyroidism.
