These tumors, which usually develop in adolescence or adulthood, are called malignant peripheral nerve sheath tumors. People with neurofibromatosis type 1 also have an increased risk of developing other cancers, including brain tumors and cancer of blood-forming tissue (leukemia). During childhood, benign growths called Lisch nodules often appear in the colored part of the eye (the iris). Lisch nodules do not interfere with vision. Some affected individuals also develop tumors that grow along the nerve leading from the eye to the brain (the optic nerve).
Depending on how serious the symptoms are, is how long the person will live. They may live as long as a normal person. In LOTS, the body makes small amounts of hex A. People with LOTS inherit the late-onset hex A, gene from both parents or inherit one late-onset gene and one inactive gene. Tay-Sachs disease results from defects in a gene on chromosome 15 that codes for production of the enzyme Hex-A.
Obstruction most commonly occurs with stones in the ureters, bladder, or urethra; however, trauma, edema associated with infection, and prostate enlargement also cause postrenal failure.1 Statistics In the United States, the annual incidence of acute renal failure is 100 cases for every million people. It’s diagnosed in 1% of hospital admissions. Pathophysiology There is a generally unexpected decrease in kidney function, which may or may not be associated with a
In more advanced stages, there is also a thinning of the light-sensitive layer of cells in the macula leading to atrophy, or tissue death. Patients may have blind spots in the center of their vision. In advanced stages patients lose their central vision. Wet form: is characterized by the growth of abnormal blood vessels from the chorid underneath the macula. This is called choridal neovascularization.
Unfortunately there is no cure for CP, but there are treatments, therapy, and in some cases sugary to help the child live with the condition. Cerebral Palsy is one of the most common congenital disorders of childhood. An average of half a million adults and children suffer from CP in the United States. This disorder affects both complex and simple muscle coordination and also affects normal vital functions such as breathing, bladder and bowel control, eating and learning. Fortunately CP does not get worse over time.
Tamara Wolter 04/21/2011 A & P 2 Creutzfeldt-Jacob Disease Creutzfeldt-Jacob disease (CJD) is the best known of a group of diseases called prion disease, which affect a form of protein found in the central nervous system and causes dementia. It was first reported by two German doctors (Creutzfeldt and Jacob) in 1920, although it has been well recognized in animals for centuries. It affects about one person in every one million people per year worldwide. Typically, onset of symptoms occurs about age 60, and about 90 percent of individuals die within 1 year. There are three major categories of CJD: In sporadic CJD, the disease appears even thought the person has no known risk factors for the disease.
Coronary Artery Disease Coronary Artery Disease is also known by other names such as, Atherosclerosis, hardening of the ateries, heart disease, Ischemic heart disease and narrowing of the arteries. Coronary Artery Disease is where one or more of the arteries supplying blood to the heart muscle become blocked. It is a disease in which a waxy substance called plaque builds up inside the coronary arteries. These arteries supply oxygen rich blood to the heart muscle. Atherosclerosis is a multi focal, smoldering immunoinflammatory disease of medium sized and large arteries filled by lipids.
Kidneys: A wide range of kidney diseases can occur in Alagille syndrome. The kidneys can also have decreased function. (1,3) [pic] One of the major elements of Alagille disease is malfunctions to the liver. Liver damage can be caused by abnormalities in the bile ducts. Bile ducts carry bile from the liver to the gallbladder, and bile is what helps to digest fats.These bile ducts may be limited and tight, so the bile gets trapped and will build up inside the bile ducts which prevent the liver from working to its best ability (1,3).
KIDNEY STONES A kidney stone is a hard, crystalline mineral material formed within the kidney or urinary tract. Kidney stones are a common cause of blood in the urine (hematuria) and often severe pain in the abdomen, flank, or groin. Kidney stones are sometimes called renal calculi. The condition of having kidney stones is termed nephrolithiasis. Having stones at any location in the urinary tract is referred to as urolithiasis, and the term ureterolithiasisis used to refer to stones located in the ureters Those at Risk: Anyone may develop a kidney stone, but people with certain diseases and conditions or those who are taking certain medications are more susceptible to their development.
It could be chronic and is caused by the narrowing of the coronary artery and limitation of blood supply to part of the muscle. It also could be acute, which is the result from plaque suddenly rupturing. The inner wall of an artery is damaged. Some fatty deposits or plaques made up of cholesterol and other cellular waste products will accumulate at a site of injury in a process called atherosclerosis, the hardening of arteries. If the surface of the plaques break or rupture, blood cells, called platelets will clump or clot at that site to try and repair the artery.
