Chronic fatigue syndrome (CFS), also known as myalgic encephalomyelitis (ME), post-viral fatigue syndrome (PVFS) and various other names, is a syndrome of unknown and possibly multiple etiology, affecting the central nervous system (CNS), immune, and many other systems and organs. Most definitions other than the 1991 UK "Oxford", require a number of features, the most common being severe mental and physical depletion, which according to the 1994 Fukuda definition is "unrelieved by rest", and is usually made worse by even trivial exertion (controver ...

Adenoma is a benign epithelial tumor arising in epithelium of mucosa (stomach, small intestine and bowel), glands (endocrine and exocrine) and ducts. In hollow organs (digestive tract) the adenoma grows upwards into the lumen - adenomatous polyp or polypoid adenoma. Depending on the type of the insertion base, adenoma may be pedunculated (lobular head with a long, slender stalk, covered ...

Medical evaluation is sometimes necessary to recognize the few children with serious conditions from the majority who have entered puberty early but are still medically normal. Children (esp. girls) who are obese are more likely to physically mature earlier. Precocious puberty can make a child able to conceive when very young. Both sexes have become parents before age 10. The youngest mother on record is Lina Medina, who gave ...

11β-OH CAH resembles 21-hydroxylase deficient CAH in its androgenic manifestations: partial virilization and ambiguous genitalia of genetically female infants, childhood virilization of both sexes, and rarer cases of virilization or infertility of adolescent and adult women. The mineralocorticoid effect differs: hypertension is usually the clinical clue that a patient has 11- rather than 21-hydroxylase CAH. Diagnosis of 11β-OH CAH is usually confirmed by demonstration of marked elevations of 11-deoxycortisol and 11-deoxycorticosterone (DOC ...

The disease is caused by mutations of the VHL gene on the short arm of the third chromosome (3p26-p25). The resultant protein is produced in two forms, an 18 kDa and a 30 kDa protein that functions as a tumor suppressor gene. The main action of the VHL protein is thought to be its E3 ubiquitin ligase activity that results in specific target proteins being 'marked' for degradation. The most researched of these targets is hypoxia inducible factor 1a (HIF1a), a transcription factor that induces the expression of a number of angiogenesis ...

In 1997, Dr. Lit-Hung Leung conducted a study of 45 Asian males and 55 Asian females. He found that acne could be related to a B5 deficiency. According to the study, despite the fact that deficiency in B5 in our diet is rare, one of the possible causes of acne is a B5 deficiency. This is due to the fact that Coenzyme-A is made from B5, and while the body has enough B5 to produce sex-hormones, it does not have enough to produce sex hormones and metabolise fatty-acids together. When there is enough B5 in the body, there will be enough Coenzyme ...

Problems caused to persons with lipoid CAH can be divided into (1) mineralocorticoid deficiency, (2) glucocorticoid deficiency, (3) sex steroid deficiency, and (4) damage to gonads caused by lipid accumulation. Lipoid congenital adrenal hyperplasia - Mineralocorticoid deficiency. Most infants born with lipoid CAH have had genitalia female enough that no disease was suspected at birth. Because the adrenal zona glomerosa is undifferentiated and inactive before delivery, it is undamaged at birth ...

Infertility - Primary vs. secondary. According to the American Society for Reproductive Medicine, infertility affects about 6.1 million people in the U.S., equivalent to ten percent of the reproductive age population. Female infertility accounts for one third of infertility cases, male infertility for another third, combined male and female infertility for another 15%, and the remainder of cases are "unexplained"2. A Robertsonian translocation in either partner may cause recurr ...

The cause of CFS is unknown, although a large number of causes have been proposed, and several proposed causes have very vocal and partisan advocates. As there is no one identifiable cause or falsifiable diagnosis for CFS, there is also no one treatment protocol or "magic bullet". Due to the multi-systemic nature of the illness, and others like it, an emerging branch of medical science called psychoneuroimmunology is exploring how all the various theories fit together. The treatments that are proposed and often attempted for CF ...

As evolution drove the emergence of multicellular organisms it became necessary to develop “coordinating systems to regulate and integrate the function of differentiating cells” (Griffin and Ojeda 2000). Two mechanisms perform this function in higher animals, the nervous system and the endocrine system. Unlike the former, which sends and receives information via electrochemical signals, the endocrine system performs its regulatory function through the detection, production and release (generally into the bloodstream) of chemical agents. ...

Management of salt-wasting crises and mineralocorticoid treatment are as for other forms of salt-wasting congenital adrenal hyperplasia: saline and fludrocortisone. Glucocorticoids can be provided at minimal replacement doses because there is no need for suppression of excessive adrenal androgens or mineralocorticoids. As with other forms of adrenal insufficiency, extra glucocorticoid is needed for stress coverage. XX females with lipoid CAH may need estrogen replacement at or after puberty. To date, ovulation and pregnancy has not been reported even with early diagnosis and carefu ...

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 ...

Our understanding of the molecular basis for this disease has been advanced in the last decade by better understanding of adrenal steroidogenesis as well as genetic studies of affected patients. It used to be assumed that lipoid adrenal hyperplasia resulted from a defect of the enzymes that converted cholesterol to pregnenolone. The conversion reactions are mediated by a single enzyme, formerly referred to as 20,22-desmolase, but now identified as P450scc (side chain cleavage enzyme). However, as of 2003, only a si ...

According to the 1994 Fukuda definition there are eight main categories of symptoms in CFS: Fatigue: People with CFS experience profound, overwhelming exhaustion, both mental and physical, which is worsened by exertion, and is not relieved (or not completely relieved) by rest. To receive a diagnosis of CFS, this fatigue state must last for six months. Pain: Pain in CFS may include muscle pain, joint pain (without joint swelling or redness, and may be transitory), headaches (particularly of a new type, severity, or durat ...

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 ...

Features of VHL are: angiomatosis - little knots of capillaries in various organs. These tend to be cavernous hemangiomas, which are sharply defined, sponge-like tumors composed of large, dilated, cavernous vascular spaces. hemangioblastomas - tumors of the central nervous system (CNS, especially the cerebellum). These tumors, whether benign (usual) or malignant (rarer), may cause problems, for example angiomas in the brain or spinal cord may press on nerve or brain tissue. As an angioma grows, the walls of the blood ve ...

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 ...
