Question: What causes Hemolytic Uremic Syndrome in Children ?

Answer: The most common cause of hemolytic uremic syndrome in children is an Escherichia coli (E. coli) infection of the digestive system. The digestive system is made up of the gastrointestinal, or GI, tracta series of hollow organs joined in a long, twisting tube from the mouth to the anusand other organs that help the body break down and absorb food.
                
Normally, harmless strains, or types, of E. coli are found in the intestines and are an important part of digestion. However, if a child becomes infected with the O157:H7 strain of E. coli, the bacteria will lodge in the digestive tract and produce toxins that can enter the bloodstream. The toxins travel through the bloodstream and can destroy the red blood cells. E.coli O157:H7 can be found in
                
- undercooked meat, most often ground beef  - unpasteurized, or raw, milk  - unwashed, contaminated raw fruits and vegetables  - contaminated juice  - contaminated swimming pools or lakes
                
Less common causes, sometimes called atypical hemolytic uremic syndrome, can include
                
- taking certain medications, such as chemotherapy  - having other viral or bacterial infections  - inheriting a certain type of hemolytic uremicsyndrome that runs in families
                
More information about foodborne illnesses and the digestive system is provided in the NIDDK health topic, foodborne illnesses.
Question: What are the complications of Knee Replacement ?

Answer: While new technology and advances in surgical techniques have greatly reduced the risks involved with knee replacements, there are still some risks you should be aware of. Two of the most common possible problems are blood clots and infection. Preventing Blood Clots Blood clots can occur in the veins of your legs after knee replacement surgery. To reduce the risk of clots, your doctor may have you elevate your leg periodically and prescribe special exercises, support hose, or blood thinners. Preventing Infections Infection can occur when bacteria enter the bloodstream from skin or urinary tract infections. To reduce the risk of infection, your doctors may prescribe antibiotics for you to take prior to your surgery and for a short time afterward. Other Complications Other complications, such as new or ongoing pain, stiffness, fracture, bleeding, or injury to the blood vessels can occur. Serious medical complications, such as heart attack or stroke, are very rare. Warning Signs To Watch For To minimize the risk of complications, it is important to recognize signs of potential problems early and contact your doctor. For example, tenderness, redness, and swelling of your calf or swelling of your thigh, ankle, calf, or foot could be warning signs of a possible blood clot. Warning signs of infection include fever or chills, tenderness and swelling of the wound, and drainage from the wound. You should call your doctor if you experience any of these symptoms. It is important to get instructions from your doctor before leaving the hospital and follow them carefully once you get home. Doing so will give you the greatest chance of a successful surgery.

                    Renal cell cancer is a disease in which malignant (cancer) cells form in tubules of the kidney.
                    Renal cell cancer (also called kidney cancer or renal adenocarcinoma) is a disease in which malignant (cancer) cells are found in the lining of tubules (very small tubes) in the kidney. There are 2 kidneys, one on each side of the backbone, above the waist. Tiny tubules in the kidneys filter and clean the blood. They take out waste products and make urine. The urine passes from each kidney through a long tube called a ureter into the bladder. The bladder holds the urine until it passes through the urethra and leaves the body.     Cancer that starts in the ureters or the renal pelvis (the part of the kidney that collects urine and drains it to the ureters) is different from renal cell cancer. (See the PDQ summary about Transitional Cell Cancer of the Renal Pelvis and Ureter Treatment for more information).
Question: What is (are) Colon Cancer ?

Answer: Key Points
                    - Colon cancer is a disease in which malignant (cancer) cells form in the tissues of the colon.    - Health history affects the risk of developing colon cancer.    - Signs of colon cancer include blood in the stool or a change in bowel habits.    - Tests that examine the colon and rectum are used to detect (find) and diagnose colon cancer.    - Certain factors affect prognosis (chance of recovery) and treatment options.
                
                
                    Colon cancer is a disease in which malignant (cancer) cells form in the tissues of the colon.
                    The colon is part of the bodys digestive system. The digestive system removes and processes nutrients (vitamins, minerals, carbohydrates, fats, proteins, and water) from foods and helps pass waste material out of the body. The digestive system is made up of the esophagus, stomach, and the small and large intestines. The colon (large bowel) is the first part of the large intestine and is about 5 feet long. Together, the rectum and anal canal make up the last part of the large intestine and are about 6-8 inches long. The anal canal ends at the anus (the opening of the large intestine to the outside of the body).      Gastrointestinal stromal tumors can occur in the colon. See the PDQ summary on Gastrointestinal Stromal Tumors Treatment for more information.    See the PDQ summary about Unusual Cancers of Childhood Treatment for information about colorectal cancer in children.

Question: What is (are) Griscelli syndrome ?

Answer: Griscelli syndrome is an inherited condition characterized by unusually light (hypopigmented) skin and light silvery-gray hair starting in infancy. Researchers have identified three types of this disorder, which are distinguished by their genetic cause and pattern of signs and symptoms.  Griscelli syndrome type 1 involves severe problems with brain function in addition to the distinctive skin and hair coloring. Affected individuals typically have delayed development, intellectual disability, seizures, weak muscle tone (hypotonia), and eye and vision abnormalities. Another condition called Elejalde disease has many of the same signs and symptoms, and some researchers have proposed that Griscelli syndrome type 1 and Elejalde disease are actually the same disorder.  People with Griscelli syndrome type 2 have immune system abnormalities in addition to having hypopigmented skin and hair. Affected individuals are prone to recurrent infections. They also develop an immune condition called hemophagocytic lymphohistiocytosis (HLH), in which the immune system produces too many activated immune cells called T-lymphocytes and macrophages (histiocytes). Overactivity of these cells can damage organs and tissues throughout the body, causing life-threatening complications if the condition is untreated. People with Griscelli syndrome type 2 do not have the neurological abnormalities of type 1.  Unusually light skin and hair coloring are the only features of Griscelli syndrome type 3. People with this form of the disorder do not have neurological abnormalities or immune system problems.
Question: What are the genetic changes related to glycogen storage disease type 0 ?

Answer: Mutations in the GYS1 gene cause muscle GSD 0, and mutations in the GYS2 gene cause liver GSD 0. These genes provide instructions for making different versions of an enzyme called glycogen synthase. Both versions of glycogen synthase have the same function, to form glycogen molecules by linking together molecules of the simple sugar glucose, although they perform this function in different regions of the body.  The GYS1 gene provides instructions for making muscle glycogen synthase; this form of the enzyme is produced in most cells, but it is especially abundant in heart (cardiac) muscle and the muscles used for movement (skeletal muscles). During cardiac muscle contractions or rapid or sustained movement of skeletal muscle, glycogen stored in muscle cells is broken down to supply the cells with energy.  The GYS2 gene provides instructions for making liver glycogen synthase, which is produced solely in liver cells. Glycogen that is stored in the liver can be broken down rapidly when glucose is needed to maintain normal blood sugar levels between meals.  Mutations in the GYS1 or GYS2 gene lead to a lack of functional glycogen synthase, which prevents the production of glycogen from glucose. Mutations that cause GSD 0 result in a complete absence of glycogen in either liver or muscle cells. As a result, these cells do not have glycogen as a source of stored energy to draw upon following physical activity or fasting. This shortage of glycogen leads to the signs and symptoms of GSD 0.
