Lymphedema, also spelled lymphoedema. Lymphedema is the chronic swelling or feeling of tightness in the arm or hand due to an accumulation of lymphatic fluid in the soft tissue of the arm. The condition arises when lymph vessels, which normally carry excess fluid out of the limbs and back into central circulation, have had their flow interrupted. Lymphedema is a common complication of cancer and cancer treatment and can result in long-term physical, psychological, and social issues for patients. Lymphedema may be inherited (primary) or caused by injury to the lymphatic vessels (secondary).

Lymphedema is most often seen after lymph node dissection, surgery and/or radiation therapy, in which harm to the lymphatic system is caused during the treatment of cancer, most eminently breast cancer. Lymphedema may also be associated with accidents or certain diseases or problems that may inhibit the lymphatic system from functioning properly. In tropical areas of the world, a common cause of secondary lymphedema is filariasis, a parasitic infection. It can also be caused by a compromising of the lymphatic system resulting from cellulitis. Lymphedema can develop in any part of the body or limb.

Signs or symptoms of lymphedema to watch out for comprise: a full sensation in the limb, skin feeling tight, decreased flexibility in the hand, wrist or ankle, difficulty fitting into clothing in one specific area, or ring/wristwatch/bracelet tightness. Lymphedema is aggravated by prolonged standing, pregnancy, obesity, hot weather, and the menstrual period. Treatment for lymphedema varies depending on the severity of the edema and the degree of fibrosis of the affected limb. The most important aspect of treatment is learning how to care for your health.

The most common treatments for lymphedema are a combination of complete decongestive therapy, compression bandaging, and the employ of solidity garments. Lymphedema is also treated by physical ways and with medication. Physical methods include supporting the arm or leg in a raised position, manual lymphatic drainage, wearing bandages or custom-fitted clothing. Prevention is better than cure. Maintain your ideal body weight. Eat foods high in fiber such as whole-grain breads, cereals, pasta, rice, fresh fruits and vegetables. Eat a variety of foods to get all the nutrients you require.

Percocet is a trademarked, potent compound painkiller used to treat moderately severe to severe acute (short-term) pain. The main ingredient of Percocet is oxycodone, a potent opioid agonist; in addition, the drug contains paracetamol, also known as acetaminophen. It is notable for its potential for drug abuse.

The U.S. Food and Drug Administration first approved Percocet in 1976, under application ANDA 085106.

Pharmacology

Endo Pharmaceuticals currently manufactures Percocet, as well as Percodan which contains oxycodone and aspirin. Percocet tablets are available in six combinations of oxycodone hydrochloride and acetaminophen, with different appearances and maximum daily doses:

* 2.5 mg oxycodone HCl & 325 mg acetaminophen: pink oval tablet, maximum daily dose 12 tablets

* 5 mg oxycodone HCl & 325 mg acetaminophen: blue round tablet, maximum daily dose 12 tablets

* 7.5 mg oxycodone HCl & 325 mg acetaminophen: peach oval tablet, maximum daily dose 8 tablets

* 7.5 mg oxycodone HCl & 500 mg acetaminophen: peach capsule-shaped tablet, maximum daily dose 8 tablets

* 10 mg oxycodone HCl & 325 mg acetaminophen: yellow capsule-shaped tablet, maximum daily dose 6 tablets

* 10 mg oxycodone HCl & 650 mg acetaminophen: yellow oval tablet, maximum daily dose 6 tablets

For the 2.5 mg oxycodone HCl tablet, the usual dose is 1-2 tablets every six hours as needed for pain; for the other tablets, the usual dose is 1 tablet every six hours as needed for pain.

Watson Laboratories manufactures generic versions of five of the six types of Percocet tablets (with 5, 7.5, and 10 mg oxycodone HCl).

Menkes syndrome is an inborn error of metabolism in which cells in the body cannot absorb enough copper. Copper added at oddly low levels in the liver and brain, but at elevated than normal levels in the kidney and intestinal lining. The disorder causes severe cerebral degeneration and arterial changes, resulting in death in infancy. The disease can often be diagnosed by looking at a victim’s hair, which appears to be both whitish and kinked when viewed under a microscope. There is often extensive neurodegeneration in the gray matter of the brain. Menkes’ disease is transmitted as an X-linked recessive trait.

A condition is considered X-linked if the transformed gene that causes the disorder is sited on the X chromosome, one of the two sex chromosomes. In males, one altered copy of the gene in each cell is enough to cause the condition. In females, a mutation must be present in both copies of the gene to cause the disorder. Males are affected by X-linked recessive disorders much more frequently than females. A number of other diseases, including type IX Ehlers-Danlos syndrome, may be the result of allelic mutations and it is hoped that research into these diseases may prove useful in fighting Menkes’ disease. About 1 in 300,000 individuals are affected.

About one-third of cases results from new mutations in the gene and occurs in people with no history of the disorder in their family. Menkes syndrome is characterized by thin and coarse hair, growth failure, and deterioration of the nervous system. Extra signs and symptoms comprise weak muscle tone, sagging facial features, seizures, mental retardation, and developmental delay. In rare cases, symptoms begin later in childhood and are less severe. Symptoms appear during infancy and are largely a result of abnormal intestinal copper absorption with secondary deficiency in copper-dependent mitochonrial enzymes.

Normal or faintly slowed development may proceed for 2 to 3 months, and then there will be severe developmental delay and a loss of premature developmental skills. Menkes syndrome affected children may be born prematurely, but appear healthy at birth and develop normally for 6 to 8 weeks. Treatment usually only helps when started very early in the course of the disease. Treatment with daily copper injections may improve the outcome in Menkes disease if it begins within days after birth. Other treatment is symptomatic and supportive. See a genetic counselor if you want to have children and you have a family history of Menkes syndrome.
