Anisakidosis: a cause of intestinal obstruction from eating sushi.

We report a case of strangulating small bowel obstruction in a 60-yr-old Japanese woman caused by anisakidosis (previously known as anisakiasis). With the increasing popularity of Japanese cuisine such as sushi in the United States, the incidence of anisakidosis is expected to increase. Intestinal anisakidosis can now be treated temporarily, but this condition may cause a serious obstruction afterwards, as evidenced by this particular case. Over 13,500 cases were reviewed in both the Japanese and English literature, and we discuss the prevention of anisakidosis without negatively altering the taste of the raw fish.

Mucosal microhernias in the nonhuman primate colon: their role in the pathogenesis of colonic disease.

Microhernias of colonic mucosal glands through the muscularis mucosae are common in human and nonhuman primate colons, and are related to submucosal lymphoid nodules. In nonhuman primates they have been shown to play an important role in the spread of inflammatory diseases from the lamina propria to the submucosa by allowing the infective agents to pass through the muscularis mucosae. The lymphoid tissue of the alimentary tract is composed predominantly of B lymphocytes and produces humoral antibodies. This property of the lymphoid component of these microhernias may thus play a significant role in determining which infective colonic diseases penetrate into the submucosa and which remain largely confined to the lamina propria.
