In the large intestine
Ischemia of the large intestine (colon) is termed ischemic colitis. Although uncommon in the general population, ischemic colitis occurs with greater frequency in the elderly, and is the most common form of bowel ischemia. Causes of the reduced blood flow can include changes in the systemic circulation (e.g. low blood pressure) or local factors such as constriction of blood vessels or a blood clot. In most cases, no specific cause can be identified.Ischemic colitis is usually suspected on the basis of the clinical setting, physical examination, and laboratory test results; the diagnosis can be confirmed by endoscopy or by using sigmoid or endoscopic placement of a visible light spectroscopic catheter (see Diagnosis). Ischemic colitis can span a wide spectrum of severity; most patients are treated supportively and recover fully, while a minority with very severe ischemia may develop sepsis and become critically, sometimes fatally, ill.Patients with mild to moderate ischemic colitis are usually treated with IV fluids, analgesia, and bowel rest (that is, no food or water by mouth) until the symptoms resolve. Those with severe ischemia who develop complications such as sepsis, intestinal gangrene, or bowel perforation may require more aggressive interventions such as surgery and intensive care. Most patients make a full recovery; occasionally, after severe ischemia, patients may develop long-term complications such as a stricture or chronic colitis. References

Chromhidrosis is a rare condition characterized by the secretion of colored sweat. It is caused by the deposition of lipofuscin in the sweat glands. Cases of red, blue, green, yellow, pink, and black sweat have been reported. Usually, chromhidrosis affects the apocrine glands, mainly on the face and underarms. A limited number of treatment options exist, including regular application of capsaicin cream, and prolonged relief may be provided by botulinum toxin treatment. Chromogenic pigments produced by bacteria (Corynebacterium in particular) are implicated in this condition, but their exact role still requires careful microbiological elucidation. Chromhidrosis of the eccrine glands is rare; it occurs mainly after the ingestion of certain dyes or drugs. See also
