1/3. GI anthrax: report of one case confirmed with autopsy.

    BACKGROUND: bacillus Anthraces is a non-motile, rod like, gram-positive and aerobic bacillus that produces central oval-shaped spores and characterized by rough, irregular and often comma-shaped colonies in blood agar. About 95% of human anthrax is cutaneous and 5% respiratory. GI anthrax, a very rare type, has been reported in less than 1% of all cases. We thus report a case of GI anthrax with autopsy findings. CASE REPORT: A 15-year-old young adult man was admitted to our hospital with history of fever, abdominal pain and bloody diarrhea from 48 hours after ingestion of half-cooked sheep's meat. In endoscopic exam of upper GI tract, the esophagus had been filled with fresh blood without any varices, stomach showed evidence of hemorrhage and had multiple erosion but no ulceration of duodenum. penicillin g 24,000,000 U/day IV was started but unfortunately severe upper and lower GI hemorrhage developed, leading to hypotension and death. In autopsy, ascites, paraaortic and mesenteric lymphadenopathy was accident with some of them being hemorrhagic. The spleen was slightly enlarged with hemorrhagic congestion in some parts of it. In the blood sample drawn from the spleen, the filamentous bacillus was successfully found. CONCLUSIONS: Because of the fatal nature of the disease and the similarity of the signs and symptoms to the other gastrointestinal diseases, we should consider it as one of the probable differential diagnosis in the patients with upper and lower gastrointestinal bleeding with fever esp. in the endemic areas.

2/3. eikenella corrodens, a rare cause of pancreatic abscess: two case reports and review.

    eikenella corrodens, a slowly growing gram-negative bacillus that is a normal inhabitant of dental plaque, has been recognized as an infrequent cause of invasive disease. To date, only one case of pancreatic abscess due to E. corrodens in association with other bacteria from the oropharynx has been described. We report herein two cases of pancreatic abscess due to E. corrodens. In one case E. corrodens and escherichia coli were found in the abscess specimens; in the other case no other pathogen was associated with E. corrodens. In addition, we review descriptions from the literature of abdominal infections caused by E. corrodens.

3/3. streptococcus bovis infection of the central nervous system: report of two cases and review.

    streptococcus bovis is an uncommon cause of meningitis and subdural empyema. We report one case each of meningitis and subdural empyema in which S. bovis biotype II was isolated from both the spinal fluid and blood. In one case, the organisms were seen on a gram-stained preparation of cerebrospinal fluid. The first patient presented with gastrointestinal symptoms of unknown etiology, was immunosuppressed, and recovered. The second patient presented with syncope, developed a subdural empyema, and died; at autopsy, a colonic adenoma was found. A review of the English-language literature revealed only 14 previously reported cases of meningitis due to S. bovis and no cases of subdural empyema due to S. bovis. These cases indicate the importance of complete laboratory identification of specific organisms and confirm the need for a thorough neurological examination and search for underlying gastrointestinal disease in cases of S. bovis infection.
