Dientamoeba fragilis. An unusual intestinal pathogen.

This is a case report of a gastrointestinal infection caused by Dientamoeba fragilis. It is a flagellate protozoan that is an uncommon etiology of gastrointestinal disease. Primarily characterized by diarrhea and abdominal pain, other symptoms such as flatulence, nausea, vomiting, fatigue, malaise, and weight loss occur. Diagnosis is made using multiple fresh stool samples that are preserved and permanently stained looking for the typical binucleate trophozoite. Since there is a distinct association with Enterobius vermicularis (possibly the mode of protozoan transmission), the human pinworm is also sought. Treatment of choice consists of diiodohydroxyquin in adults and metronidazole in children.

Maine's urchin diver: a survey of diving experience, medical problems, and diving-related symptoms.

A questionnaire was sent to 1,545 licensed, hand-harvesting Maine urchin divers to survey diving experience, habits, environment, medical problems, and symptoms; 323 surveys were returned. Most of the respondents were young males who considered themselves physically fit; however, 17% were over 41 and 4% considered themselves "out of shape." Most had more than one occupation. Only 2% admitted no formal training, and breadth of experience fell into a trimodal distribution. Over half dove 2-5 times daily, most often under 60 ft. "Bounce" diving without decompression stops was usual, and solo diving was frequent. Eighteen percent had chronic medical problems, and 11% chronically used medications. The majority of diving was vigorous work from boats in the cold Maine ocean, not infrequently during poor weather. Seventy-eight percent described diving-related symptoms, and 2% admitted to recompression therapy. Thus, these respondents depict themselves diving within marginal safety boundaries.

Plant thorn granuloma.

Plant thorn granuloma is a little-reported sequela to the pricking injury caused by a thorn. The retained organic material stimulates an inflammatory foreign body reaction that is localized to the skin. This can be a significant aggravation to the patient, causing pain, swelling, and an unsightly nodule. Simple excision as an outpatient can be curative.
