Question:  Who is at risk for Hepatitis B: What Asian and Pacific Islander Americans Need to Know? ?
Answer: Since 1986, a hepatitis B vaccine has been available and should be given to newborns and children in the United States. The vaccine, however, is unavailableor has only recently become availablein many parts of the world. You are at higher risk for hepatitis B if you or your mother was born in a region of the world where hepatitis B is common, meaning 2 percent or more of the population is chronically infected with the hepatitis B virus.1 In most Asian and Pacific Island nations, 8 to 16 percent of the population is chronically infected.2
Question:  What are the symptoms of Hepatitis B: What Asian and Pacific Islander Americans Need to Know ?
Answer: Hepatitis B is called a silent killer because many people have no symptoms, so the disease often progresses unnoticed for years. Unfortunately, many people first learn they have chronic hepatitis B when they develop symptoms of severe liver damage, which include
                
- yellowish eyes and skin, called jaundice  - a swollen stomach or ankles  - tiredness  - nausea  - weakness  - loss of appetite  - weight loss  - spiderlike blood vessels, called spider angiomas, that develop on the skin
Question:  Who is at risk for Hepatitis B: What Asian and Pacific Islander Americans Need to Know? ?
Answer: Anyone can get hepatitis B, but some people are at higher risk, including
                
- people who were born to a mother with hepatitis B  - people who have close household contact with someone infected with the hepatitis B virus  - people who have lived in parts of the world where hepatitis B is common, including most Asian and Pacific Island nations  - people who are exposed to blood or body fluids at work  - people on hemodialysis  - people whose sex partner(s) has hepatitis B  - people who have had more than one sex partner in the last 6 months or have a history of sexually transmitted disease  - injection drug users  - men who have sex with men
Question:  What is (are) Acquired Cystic Kidney Disease ?
Answer: Acquired cystic kidney disease happens when a person's kidneys develop fluid-filled sacs, called cysts, over time. Acquired cystic kidney disease is not the same as polycystic kidney disease (PKD), another disease that causes the kidneys to develop multiple cysts.
                
Acquired cystic kidney disease occurs in children and adults who have
                
- chronic kidney disease (CKD)a condition that develops over many years and may lead to end-stage kidney disease, or ESRD. The kidneys of people with CKD gradually lose their ability to filter wastes, extra salt, and fluid from the blood properly.  - end-stage kidney diseasetotal and permanent kidney failure that requires a kidney transplant or blood-filtering treatments called dialysis.
                
The cysts are more likely to develop in people who are on kidney dialysis. The chance of developing acquired cystic kidney disease increases with the number of years a person is on dialysis. However, the cysts are caused by CKD or kidney failure, not dialysis treatments.
                
More information is provided in the NIDDK health topics, kidney failureand dialysis.
Question:  What is (are) Acquired Cystic Kidney Disease ?
Answer: Acquired cystic kidney disease differs from PKD in several ways. Unlike acquired cystic kidney disease, PKD is a genetic, or inherited, disorder that can cause complications such as high blood pressure and problems with blood vessels in the brain and heart.
                
The following chart lists the differences:
                
People with Polycystic Kidney Disease   - are born with a gene that causes the disease   - have enlarged kidneys   - develop cysts in the liver and other parts of the body   People with Acquired Cystic Kidney Disease   - do not have a disease-causing gene   - have kidneys that are normal-sized or smaller   - do not form cysts in other parts of the body
                
In addition, for people with PKD, the presence of cysts marks the onset of their disease, while people with acquired cystic kidney disease already have CKD when they develop cysts.
                
More information is provided in the NIDDK health topic, Polycystic Kidney Disease.
Question:  How many people are affected by Acquired Cystic Kidney Disease ?
Answer: Acquired cystic kidney disease becomes more common the longer a person has CKD.
                
- About 7 to 22 percent of people with CKD already have acquired cystic kidney disease before starting dialysis treatments.  - Almost 60 percent of people on dialysis for 2 to 4 years develop acquired cystic kidney disease.1  - About 90 percent of people on dialysis for 8 years develop acquired cystic kidney disease.1
Question:  What causes Acquired Cystic Kidney Disease ?
Answer: Researchers do not fully understand what causes cysts to grow in the kidneys of people with CKD. The fact that these cysts occur only in the kidneys and not in other parts of the body, as in PKD, indicates that the processes that lead to cyst formation take place primarily inside the kidneys.2
Question:  What are the symptoms of Acquired Cystic Kidney Disease ?
Answer: A person with acquired cystic kidney disease often has no symptoms. However, the complications of acquired cystic kidney disease can have signs and symptoms.
Question:  What are the complications of Acquired Cystic Kidney Disease ?
Answer: People with acquired cystic kidney disease may develop the following complications:
                
- an infected cyst, which can cause fever and back pain.  - blood in the urine, which can signal that a cyst in the kidney is bleeding.  - tumors in the kidneys. People with acquired cystic kidney disease are more likely than people in the general population to have cancerous kidney tumors. However, the chance of cancer spreading is lower in people with acquired cystic kidney disease than that of other kidney cancers not associated with acquired cystic kidney disease, and the long-term outlook is better.1
Question:  How to diagnose Acquired Cystic Kidney Disease ?
Answer: A health care provider may diagnose a person with acquired cystic kidney disease based on
                
- medical history  - imaging tests
                
Medical History
                
Taking a medical history may help a health care provider diagnose acquired cystic kidney disease. A health care provider may suspect acquired cystic kidney disease if a person who has been on dialysis for several years develops symptoms such as fever, back pain, or blood in the urine.
                
Imaging Tests
                
To confirm the diagnosis, the health care provider may order one or more imaging tests. A radiologista doctor who specializes in medical imaginginterprets the images from these tests, and the patient does not need anesthesia.
                
- 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 provider's office, an outpatient center, or a hospital. The images can show cysts in the kidneys as well as the kidneys' size and shape.  - Computerized tomography (CT) scans use a combination of x rays and computer technology to create images. For a CT scan, a nurse or technician 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 an x-ray technician takes the x-rays. An x-ray technician performs the procedure in an outpatient center or a hospital. CT scans can show cysts and tumors in the kidneys.  - Magnetic resonance imaging (MRI) is a test that takes pictures of the body's internal organs and soft tissues without using x-rays. A specially trained technician performs the procedure in an outpatient center or a hospital. Although the patient does not need anesthesia, a health care provider may give people with a fear of confined spaces light sedation, taken by mouth. An MRI may include the 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 from different angles to create a detailed picture of the kidneys. During the test, the patient will hear loud mechanical knocking and humming noises from the machine.
                
Sometimes a health care provider may discover acquired cystic kidney disease during an imaging exam for another condition. Images of the kidneys may help the health care provider distinguish acquired cystic kidney disease from PKD.
Question:  What are the treatments for Acquired Cystic Kidney Disease ?
Answer: If acquired cystic kidney disease is not causing complications, a person does not need treatment. A health care provider will treat infections with antibioticsmedications that kill bacteria. If large cysts are causing pain, a health care provider may drain the cyst using a long needle inserted into the cyst through the skin.
                
When a surgeon transplants a new kidney into a patient's body to treat kidney failure, acquired cystic kidney disease in the damaged kidneys, which usually remain in place after a transplant, often disappears.
                
A surgeon may perform an operation to remove tumors or suspected tumors. In rare cases, a surgeon performs an operation to stop cysts from bleeding.
                
Have Regular Screenings to Look for Cyst or Tumor Growth   Some health care providers recommend all people with end-stage kidney disease get screened for kidney cancer using CT scans or MRIs after 3 years of dialysis. People with acquired cystic kidney disease should talk with their health care provider about when to begin screening.
Question:  What to do for Acquired Cystic Kidney Disease ?
Answer: No specific diet will prevent or delay acquired cystic kidney disease. In general, a diet designed for people on hemodialysis or peritoneal dialysis reduces the amount of wastes that accumulate in the body between dialysis sessions.

Question:  What is (are) Prostate Enlargement: Benign Prostatic Hyperplasia ?
Answer: Benign prostatic hyperplasiaalso called BPHis a condition in men in which the prostate gland is enlarged and not cancerous. Benign prostatic hyperplasia is also called benign prostatic hypertrophy or benign prostatic obstruction.
                
The prostate goes through two main growth periods as a man ages. 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.
                
As the prostate enlarges, the gland presses against and pinches the urethra. The bladder wall becomes thicker. Eventually, the bladder may weaken and lose the ability to empty completely, leaving some urine in the bladder. The narrowing of the urethra and urinary retentionthe inability to empty the bladder completelycause many of the problems associated with benign prostatic hyperplasia.
Question:  What is (are) Prostate Enlargement: Benign Prostatic Hyperplasia ?
Answer: The prostate is a walnut-shaped gland that is part of the male reproductive system. The main function of the prostate is to make a fluid that goes into semen. Prostate fluid is essential for a mans fertility. The gland surrounds the urethra at the neck of the bladder. The bladder neck is the area where the urethra joins the bladder. The bladder and urethra are parts of the lower urinary tract. The prostate has two or more lobes, or sections, enclosed by an outer layer of tissue, and it is in front of the rectum, just below the bladder. The urethra is the tube that carries urine from the bladder to the outside of the body. In men, the urethra also carries semen out through the penis.
Question:  What causes Prostate Enlargement: Benign Prostatic Hyperplasia ?
Answer: The cause of benign prostatic hyperplasia is not well understood; however, it occurs mainly in older men. Benign prostatic hyperplasia does not develop in men whose testicles were removed before puberty. For this reason, some researchers believe factors related to aging and the testicles may cause benign prostatic hyperplasia.
                
Throughout 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.
                
Another 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. Scientists have noted that men who do not produce DHT do not develop benign prostatic hyperplasia.
Question:  How many people are affected by Prostate Enlargement: Benign Prostatic Hyperplasia ?
Answer: Benign prostatic hyperplasia is the most common prostate problem for men older than age 50. In 2010, as many as 14 million men in the United States had lower urinary tract symptoms suggestive of benign prostatic hyperplasia.1 Although benign prostatic hyperplasia rarely causes symptoms before age 40, the occurrence and symptoms increase with age. Benign prostatic hyperplasia affects about 50 percent of men between the ages of 51 and 60 and up to 90 percent of men older than 80.2
Question:  What are the symptoms of Prostate Enlargement: Benign Prostatic Hyperplasia ?
Answer: Lower urinary tract symptoms suggestive of benign prostatic hyperplasia may include
                
- urinary frequencyurination eight or more times a day  - urinary urgencythe inability to delay urination  - trouble starting a urine stream  - a weak or an interrupted urine stream  - dribbling at the end of urination  - nocturiafrequent urination during periods of sleep  - urinary retention  - urinary incontinencethe accidental loss of urine  - pain after ejaculation or during urination  - urine that has an unusual color or smell
                
Symptoms of benign prostatic hyperplasia most often come from
                
- a blocked urethra  - a bladder that is overworked from trying to pass urine through the blockage
                
The size of the prostate does not always determine the severity of the blockage or symptoms. Some men with greatly enlarged prostates have little blockage and few symptoms, while other men who have minimally enlarged prostates have greater blockage and more symptoms. Less than half of all men with benign prostatic hyperplasia have lower urinary tract symptoms.3
                
Sometimes men may not know they have a blockage until they cannot urinate. This condition, called acute urinary retention, can result from taking over-the-counter cold or allergy medications that contain decongestants, such as pseudoephedrine and oxymetazoline. A potential side effect of these medications may prevent the bladder neck from relaxing and releasing urine. Medications that contain antihistamines, such as diphenhydramine, can weaken the contraction of bladder muscles and cause urinary retention, difficulty urinating, and painful urination. When men have partial urethra blockage, urinary retention also can occur as a result of alcohol consumption, cold temperatures, or a long period of inactivity.
Question:  What are the complications of Prostate Enlargement: Benign Prostatic Hyperplasia ?
Answer: The complications of benign prostatic hyperplasia may include
                
- acute urinary retention  - chronic, or long lasting, urinary retention  - blood in the urine  - urinary tract infections (UTIs)  - bladder damage  - kidney damage  - bladder stones
                
Most men with benign prostatic hyperplasia do not develop these complications. However, kidney damage in particular can be a serious health threat when it occurs.
                

                
When to Seek Medical Care   A person may have urinary symptoms unrelated to benign prostatic hyperplasia that are caused by bladder problems, UTIs, or prostatitisinflammation of the prostate. Symptoms of benign prostatic hyperplasia also can signal more serious conditions, including prostate cancer.   Men with symptoms of benign prostatic hyperplasia should see a health care provider.   Men with the following symptoms should seek immediate medical care:   - complete inability to urinate   - painful, frequent, and urgent need to urinate, with fever and chills   - blood in the urine   - great discomfort or pain in the lower abdomen and urinary tract
Question:  How to prevent Prostate Enlargement: Benign Prostatic Hyperplasia ?
Answer: Researchers have not found a way to prevent benign prostatic hyperplasia. Men with risk factors for benign prostatic hyperplasia should talk with a health care provider about any lower urinary tract symptoms and the need for regular prostate exams. Men can get early treatment and minimize benign prostatic hyperplasia effects by recognizing lower urinary tract symptoms and identifying an enlarged prostate.
Question:  What to do for Prostate Enlargement: Benign Prostatic Hyperplasia ?
Answer: Researchers have not found that eating, diet, and nutrition play a role in causing or preventing benign prostatic hyperplasia. However, a health care provider can give information about how changes in eating, diet, or nutrition could help with treatment. Men should talk with a health care provider or dietitian about what diet is right for them.

Question:  What is (are) What I need to know about My Child's Urinary Tract Infection ?
Answer: A UTI is an infection in the urinary tract. Infections are caused by microbesorganisms too small to be seen without a microscope. Bacteria * are the most common cause of UTIs. Normally, bacteria that enter the urinary tract are quickly removed by the body before they cause symptoms. But sometimes bacteria overcome the bodys natural defenses and cause infection.
                
*See the Pronunciation Guide for tips on how to say the underlined words.
Question:  What causes What I need to know about My Child's Urinary Tract Infection ?
Answer: Most UTIs are caused by bacteria that live in the bowel, the part of the digestive tract where stool is changed from liquid to solid. The bacterium Escherichia coli (E. coli) causes most UTIs. The 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, or refluxing, toward the kidneys, and urination washes microbes out of the body. The bodys natural defenses also prevent infection. But despite these safeguards, infections still occur.
                
Other factors that may cause a child to get a UTI include the following:
                
- Waiting to urinate. Regular urination helps flush away bacteria. Holding urine allows bacteria to grow.  - Making too little urine. A child that doesnt drink enough fluids may not make enough urine to flush away bacteria.  - Constipation. Constipation is a condition in which a child has fewer than two bowel movements a week. Stools can be hard, dry, small, and difficult to pass. The hard stool in the bowel may press against the urinary tract and block the flow of urine, allowing bacteria to grow.
                
Some children are just more prone to UTIs than others, just as some children are more prone to getting coughs, colds, or ear infections.
