| ARTICLES RELATED TO lymph node | | | |  lymph node: Encyclopedia II - Malignant melanoma - DiagnosisAny mole that is irregular in color or shape should be examined by a doctor to determine if it is a malignant melanoma, the most serious and life-threatening form of skin cancer. Following a visual examination and a dermatoscopic exam (an instrument that illuminates a mole, revealing it's underlying pigment and vascular network structure), the doctor may biopsy the suspicious mole. If it is malignant, the mole and an area around it will need excision. This may r ...

| | | | | lymph node: Encyclopedia II - Malignant melanoma - Prevention
Malignant melanoma - Primary.
To prevent or detect melanomas (and increase survival rates), it is recommended that the public:
Learn what they look like (see "ABCDE" mnemonic below.)
Are aware of moles and check for changes (shape, size, color, itching or bleeding)
Show any suspicious moles to a doctor (preferably a dermatologist).
Minimize exposure to sources of ultraviolet radiation (the sun and sunbeds)
Follow sun protection measures. Wearing protective clothing ...

| | | | | lymph node: Encyclopedia II - Chronic fatigue syndrome - Course
Chronic fatigue syndrome - Onset.
Some cases of CFS start gradually, but the majority start suddenly, often triggered by a 'flu-like viral or similar illness. People with CFS may improve or recover completely after a few or many years, or not at all. It is not known whether any CFS sufferer has truly recovered to pre-illness levels, or whether their symptoms have merely subsided enough for them to live a more normal life. Some sufferers have a remission for months or years ...

| | | | | lymph node: Encyclopedia II - HIV - Transmission Since the beginning of the epidemic, three main transmission routes of HIV have been identified:
Sexual route. The majority of HIV infections are acquired through unprotected sexual relations. Sexual transmission occurs when there is contact between sexual secretions of one partner with the rectal, genital or mouth mucous membranes of another. According to the French ministry for health, the probability of transmission per act varies from 0.03% to 0.07% for the case of receptive vaginal sex, from 0.02 to 0.05% in the case ...

| | | | | lymph node: Encyclopedia II - Chronic fatigue syndrome - Diagnosis At this time, there is no accepted conclusive test or series of tests of chronic fatigue syndrome. CFS is therefore largely an exclusionary diagnosis. There are several sets of diagnostic criteria for the syndrome, and if a doctor suspects CFS in a patient who meets these criteria, the doctor must eliminate all other potential causes of the patient's symptoms before giving a diagnosis of CFS. "Chronic fatigue" and similar symptoms can be caused by a wide variety of conditions which must be eliminated, although in some cases, treatment ...

| | | | | | | lymph node: Encyclopedia II - Chronic fatigue syndrome - Social issues Chronic fatigue syndrome carries a considerable stigma, and has frequently been viewed as malingering, hypochondriacal behavior, "wanting attention" or "yuppie flu". As there is no objective test for the condition at this time, many argue that it is easy to "invent" CFS-like symptoms for financial, social or emotional benefits. CFS sufferers argue in turn that the perceived "benefits" are hardly as generous as some may believe, and that most CFS pa ...

| | | | | | lymph node: Encyclopedia II - Dendritic cell - Types of dendritic cells Unfortunately, there are at least two different types of cells involved with immunity that are called dendritic cells. The exact relationship of these types to each other, as well as the identity of their parent cells in vivo, remains controversial.
While humans and non-human primates such as Rhesus macaques appear to have DCs divided into these groups, other species (such as the mouse) have different subdivisions of DCs.

Myeloid dendritic cells (MDC) are most similar ...

| | | | | lymph node: Encyclopedia II - Malignant melanoma - Causes Epidemiologic studies from Australian dermatology suggest that exposure to ultraviolet radiation is one of the major contributors to the development of melanoma. Few dermatologists question the association between sunlight and melanoma. It is widely believed that occasional extreme sun exposure (resulting in "sunburn") is causally related to melanoma. Those with more chronic long term exposure (outdoor workers) may develop protective mechanisms. Melanoma is most common on the back in men and on legs in women (areas of intermittent sun exposu ...

| | | | | lymph node: Encyclopedia II - Chronic fatigue syndrome - Disease associations Some diseases show a considerable overlap with CFS, and it may be hard to distinguish between them. People with fibromyalgia have muscle pain and sleep disturbances. Those with multiple chemical sensitivities (MCS) are sensitive to chemicals and have sleep disturbances. Many veterans with Gulf War syndrome (GWS) have symptoms almost identical to CFS. Post-polio syndrome also bears a strong and remarkable resemblance to CFS. Some researchers maintain these disorders are all express ...

| | | | | lymph node: Encyclopedia II - Chronic fatigue syndrome - Epidemiology Due to problems with the definition of CFS, estimates of its prevalence vary widely. Studies in the United States have found between 75 and 420 cases of CFS for every 100,000 adults.
Far more women than men get CFS — between 60 and 85% of cases are women. Members of ethnic minorities and low income classes are slightly more likely to develop CFS. Though people of all ages can get CFS, and precise statistics are not available, the prevalence among children and adolescents appears to be lower than for adults. A ...

| | | | | lymph node: Encyclopedia II - Dendritic cell - Relationship to HIV allergy and autoimmune diseases HIV, which causes AIDS, can bind to dendritic cells via various receptors expressed on the cell. The best studied example is DC-SIGN (usually on MDC subset 1, but other subsets under certain conditions; since not all dendritic cell subsets expresss DC-SIGN, its exact role in sexual HIV-1 transmission is not clear). When the dendritic cell takes up HIV and then travels to the lymph node, the virus is able to move to helper T-cells, and this infection of helper T-cells is the major cause of disease. This knowledge has vastly altered our unders ...
