Bowel infarction or gangrenous bowel represents an irreversible injury to the intestine resulting from insufficient blood flow. It is considered a medical emergency because it can quickly result in life-threatening infection and death. Any cause of bowel ischemia, the earlier reversible form of injury, may ultimately lead to infarction if uncorrected. The causes of bowel ischemia or infarction include primary vascular causes (for example, mesenteric ischemia) and other causes of bowel obstruction. Causes
Primary vascular causes of bowel infarction, also known as mesenteric ischemia, are due to blockages in the arteries or veins that supply the bowel. Types of mesenteric ischemia are generally separated into acute and chronic processes, because this helps determine treatment and prognosis.Bowel obstruction is most often caused by intestinal adhesions, which frequently form after abdominal surgeries, or by chronic infections such as diverticulitis, hepatitis, and inflammatory bowel disease. The condition may be difficult to diagnose, as the symptoms may resemble those of other bowel disorders. Bowel volvulus describes a specific form of bowel obstruction, where the intestine and/or mesentery are twisted, resulting in ischemia. Management
An infarcted or dead intestinal segment is a serious medical problem because intestines contain non-sterile contents within the lumen. Although the fecal content and high bacterial loads of the intestine are normally safely contained, progressive ischemia causes tissue breakdown and inevitably leads to bacteria spreading to the bloodstream.
Partialism is sexual fetish with an exclusive focus on a specific part of the body other than genitals. Partialism is categorized as a fetishistic disorder in the DSM-5 of the American Psychiatric Association only if it causes significant psychosocial distress for the person or has detrimental effects on important areas of their life. In the DSM-IV, it was considered a separate paraphilia (not otherwise specified), but was merged into fetishistic disorder by the DSM-5. Individuals who exhibit partialism sometimes describe the anatomy of interest to them as having equal or greater erotic attraction for them as do the genitals.Partialism occurs in heterosexual, bisexual, and homosexual individuals. Foot fetishism is considered one of the most common partialisms. Types
The following are some of the partialisms commonly found among people:
