Question: What causes Hemochromatosis ?

Answer: The two types of hemochromatosis are primary and secondary. Each type has a different cause.
                
Primary Hemochromatosis
                
Primary hemochromatosis is caused by a defect in the genes that control how much iron you absorb from food. This form of the disease sometimes is called hereditary or classical hemochromatosis. Primary hemochromatosis is more common than the secondary form of the disease.
                
The genes usually involved in primary hemochromatosis are called HFE genes. Faulty HFE genes cause the body to absorb too much iron. If you inherit two copies of the faulty HFE gene (one from each parent), you're at risk for iron overload and signs and symptoms of hemochromatosis.
                
If you inherit one faulty HFE gene and one normal HFE gene, you're a hemochromatosis "carrier." Carriers usually don't develop the disease. However, they can pass the faulty gene on to their children. Estimates suggest that about 1 in 10 people in the United States are hemochromatosis carriers.
                
If two parents are carriers of the faulty HFE gene, then each of their children has a 1 in 4 chance of inheriting two faulty HFE genes.
                
Although less common, other faulty genes also can cause hemochromatosis. Researchers continue to study what changes to normal genes may cause the disease.
                
Secondary Hemochromatosis
                
Secondary hemochromatosis usually is the result of another disease or condition that causes iron overload. Examples of such diseases and conditions include:
                
Certain types of anemia, such as thalassemias and sideroblastic anemia
                
Atransferrinemia and aceruloplasminemiaboth are rare, inherited diseases
                
Chronic liver diseases, such as chronic hepatitis C infection, alcoholic liver disease, or nonalcoholic steatohepatitis
                
Other factors also can cause secondary hemochromatosis, including:
                
Blood transfusions
                
Oral iron pills or iron injections, with or without very high vitamin C intake (vitamin C helps your body absorb iron)
                
Long-term kidney dialysis
Question: What is (are) Graves' Disease ?

Answer: Graves disease, also known as toxic diffuse goiter, is the most common cause of hyperthyroidism in the United States. Hyperthyroidism is a disorder that occurs when the thyroid gland makes more thyroid hormone than the body needs.
                
The Thyroid
                
The thyroid is a 2-inch-long, butterfly-shaped gland in the front of the neck below the larynx, or voice box. The thyroid 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 circulate throughout the body in the bloodstream and act on virtually every tissue and cell in the body.
                
Thyroid hormones affect metabolism, brain development, breathing, heart and nervous system functions, body temperature, muscle strength, skin dryness, menstrual cycles, weight, and cholesterol levels. Hyperthyroidism causes many of the bodys functions to speed up.
                
Thyroid hormone production is regulated by another hormone called 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.
                

                
Autoimmune Disorder
                
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.
                
With Graves disease, the immune system makes an antibody called thyroid-stimulating immunoglobulin (TSI)sometimes called TSH receptor antibodythat attaches to thyroid cells. TSI mimics TSH and stimulates the thyroid to make too much thyroid hormone. Sometimes the TSI antibody instead blocks thyroid hormone production, leading to conflicting symptoms that may make correct diagnosis more difficult.
Question: Who is at risk for High Blood Pressure? ?

Answer: Not a Normal Part of Aging Nearly 1 in 3 American adults have high blood pressure. Many people get high blood pressure as they get older. However, getting high blood pressure is not a normal part of aging. There are things you can do to help keep your blood pressure normal, such as eating a healthy diet and getting more exercise. Risk Factors Anyone can develop high blood pressure. However, these factors can increase your risk for developing high blood pressure. -  age  - race or ethnicity  - being overweight  - gender  - lifestyle habits  - a family history of high blood pressure.  age race or ethnicity being overweight gender lifestyle habits a family history of high blood pressure. Age Blood pressure tends to rise with age. In fact, about 65 percent of Americans age 60 or older have high blood pressure. Race/Ethnicity High blood pressure is more common in African American adults than in Caucasian or Hispanic American adults. Compared with these ethnic groups, African Americans -  tend to get high blood pressure earlier in life  - often have higher blood pressure numbers  - are less likely to achieve target blood pressure goals with treatment. tend to get high blood pressure earlier in life often have higher blood pressure numbers are less likely to achieve target blood pressure goals with treatment. Overweight You are more likely to develop prehypertension or high blood pressure if youre overweight or obese. The terms overweight and obese refer to body weight thats greater than what is considered healthy for a certain height. Gender Before age 55, men are more likely than women to develop high blood pressure. After age 55, women are more likely than men to develop high blood pressure. Lifestyle Habits Unhealthy lifestyle habits can raise your risk for high blood pressure, and they include -  eating too much sodium or too little potassium   - lack of physical activity  - drinking too much alcohol  - smoking  - stress. eating too much sodium or too little potassium lack of physical activity drinking too much alcohol smoking stress. Family History A family history of high blood pressure raises the risk of developing prehypertension or high blood pressure. Some people have a high sensitivity to sodium and salt, which may increase their risk for high blood pressure and may run in families. Genetic causes of this condition are why family history is a risk factor for this condition.
Question: what research (or clinical trials) is being done for Non-Small Cell Lung Cancer ?

Answer: New types of treatment are being tested in clinical trials.
                    This summary section describes treatments that are being studied in clinical trials. It may not mention every new treatment being studied. Information about clinical trials is available from the NCI website.     Chemoprevention     Chemoprevention is the use of drugs, vitamins, or other substances to reduce the risk of cancer or to reduce the risk cancer will recur (come back). For lung cancer, chemoprevention is used to lessen the chance that a new tumor will form in the lung.       Radiosensitizers     Radiosensitizers are substances that make tumor cells easier to kill with radiation therapy. The combination of chemotherapy and radiation therapy given with a radiosensitizer is being studied in the treatment of non-small cell lung cancer.       New combinations    New combinations of treatments are being studied in clinical trials.
                
                
                    Patients may want to think about taking part in a clinical trial.
                    For some patients, taking part in a clinical trial may be the best treatment choice. Clinical trials are part of the cancer research process. Clinical trials are done to find out if new cancer treatments are safe and effective or better than the standard treatment.   Many of today's standard treatments for cancer are based on earlier clinical trials. Patients who take part in a clinical trial may receive the standard treatment or be among the first to receive a new treatment.   Patients who take part in clinical trials also help improve the way cancer will be treated in the future. Even when clinical trials do not lead to effective new treatments, they often answer important questions and help move research forward.
                
                
                    Patients can enter clinical trials before, during, or after starting their cancer treatment.
                    Some clinical trials only include patients who have not yet received treatment. Other trials test treatments for patients whose cancer has not gotten better. There are also clinical trials that test new ways to stop cancer from recurring (coming back) or reduce the side effects of cancer treatment.   Clinical trials are taking place in many parts of the country. See the Treatment Options section that follows for links to current treatment clinical trials. These have been retrieved from NCI's listing of clinical trials.
Question: What causes Klebsiella infection ?

Answer: What causes Klebsiella infections? Klebsiella infections refer to several different types of healthcare-associated infections that are all caused by the Klebsiella bacteria. These bacteria are usually found in human intestines where they do not cause infections. To get a Klebsiella infection, a person must be exposed to the bacteria. For example, Klebsiella must enter the respiratory (breathing) tract to cause pneumonia, or the blood to cause a bloodstream infection. Most healthy people do not get Klebsiella infections. However, people who are hospitalized and receiving treatment for other conditions may be susceptible to these infections. Klebsiella bacteria are usually spread through person-to-person contact. In healthcare settings, people who require long courses of antibiotics and and people whose care requires the use of ventilators (breathing machines) or intravenous (vein) catheters are more at risk for Klebsiella infections. How are Klebsiella bacteria spread? To get a Klebsiella infection, a person must be exposed to the bacteria. For example, Klebsiella must enter the respiratory (breathing) tract to cause pneumonia or the blood to cause a bloodstream infection. In healthcare settings, Klebsiella bacteria can be spread through person-to-person contact or, less commonly, by contamination of the environment. It is not spread through the air. Patients in healthcare settings also may be exposed to Klebsiella when they are on ventilators (breathing machines), or have intravenous (vein) catheters or wounds (caused by injury or surgery). To prevent spreading Klebsiella infections between patients, healthcare personnel must follow specific infection control precautions. These precautions may include frequent hand washing and wearing gowns and gloves when entering the rooms of patients with Klebsiellarelated illnesses. Healthcare facilities should also follow strict cleaning procedures to prevent the spread of Klebsiella. If family members are healthy, they are at very low risk of acquiring a Klebsiella infection. It is still necessary to follow all precautions, particularly hand hygiene. Klebsiella bacteria are spread mostly by person-to-person contact and hand washing is the best way to prevent the spread of germs.
Question: What are the treatments for Mevalonic aciduria ?

Answer: How might mevalonic aciduria be treated? Treatment of mevalonic aciduria remains a challenge. There is no standard treatment that is effective in all patients, so it remains mainly supportive. Treatment with simvastatin (an inhibitor of hydroxymethylglutaryl coenzyme A reductase, the enzyme that catalyzes the formation of mevalonic acid), which has been used with guarded success in patients with HIDS, worsened the clinical status of two patients with mevalonic aciduria. Anakinra, another medication used with some degree of success in HIDS patients, induced partial remission in at least one patient with mevalonic aciduria, but not all patients respond to so favorably.  Reports of successful treatment of mevalonic aciduria through allogenic bone marrow transplantation have also surfaced. At this point, this therapy is investigational and potentially applicable to patients with mevalonic aciduria whose condition is resistant to therapy with anti-inflammatory drugs (e.g., inhibitors of TNF-alpha and interleukin-1 beta). The following articles provide additional details regarding treatment of mevalonic aciduria.

Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.

Question: What are the genetic changes related to preeclampsia ?

Answer: The specific causes of preeclampsia are not well understood. In pregnancy, blood volume normally increases to support the fetus, and the mother's body must adjust to handle this extra fluid. In some women the body does not react normally to the fluid changes of pregnancy, leading to the problems with high blood pressure and urine production in the kidneys that occur in preeclampsia.  The reasons for these abnormal reactions to the changes of pregnancy vary in different women and may differ depending on the stage of the pregnancy at which the condition develops. Studies suggest that preeclampsia is related to a problem with the placenta, the link between the mother's blood supply and the fetus. If there is an insufficient connection between the placenta and the arteries of the uterus, the placenta does not get enough blood. It responds by releasing a variety of substances, including molecules that affect the lining of blood vessels (the vascular endothelium). By mechanisms that are unclear, the reaction of the vascular endothelium appears to increase factors that cause the blood vessels to narrow (constrict), and decrease factors that would cause them to widen (dilate). As a result, the blood vessels constrict abnormally, causing hypertension. These blood vessel abnormalities also affect the kidneys, causing some proteins that are normally absorbed into the blood to be released in the urine instead.  Researchers are studying whether variations in genes involved in fluid balance, the functioning of the vascular endothelium, or placental development affect the risk of developing preeclampsia. Many other factors likely also contribute to the risk of developing this complex disorder. These risk factors include a first pregnancy; a pregnancy with twins or higher multiples; obesity; being older than 35 or younger than 20; a history of diabetes, hypertension, or kidney disease; and preeclampsia in a previous pregnancy. Socioeconomic status and ethnicity have also been associated with preeclampsia risk. The incidence of preeclampsia in the United States has increased by 30 percent in recent years, which has been attributed in part to an increase in older mothers and multiple births resulting from the use of assisted reproductive technologies.
