A Case of Diabetic Foot Infection due to Leclercia adecarboxylata / 임상당뇨병

Leclercia adecarboxylata is a motile, Gram-negative, facultative anaerobic bacillus of the Enterobacteriaceae family. L. adecarboxylata is an opportunistic human pathogen that phenotypically resembles Escherichia coli, although L. adecarboxylata has been rarely isolated from clinical specimens. Here we report a case of diabetic foot infection due to L. adecarboxylata, which has never been reported in Korea.

A Case of Barium Appendicitis after a Small Bowel Series / 대한소화기내시경학회지

Barium appendicitis is a rare complication that occurs due to barium retention in the appendix after a barium study. It is believed that retained barium in the appendix forms a barium-coated fecalith and causes barium appendicitis. A 19-year-old man visited the hospital due to melena. He underwent an endoscopy and a colonoscopy but no bleeding focus was discovered. Next, a small bowel series was performed to confirm the absence of small bowel bleeding. Two weeks later, he felt right lower quadrant pain in his abdomen and developed a fever. A blood test revealed an elevated white blood cell count. A plain abdominal radiograph indicated retained barium in the appendix. A computed tomography scan revealed a dilated barium filled appendix. Thus, the pain was thought to caused by barium retention in the appendix that precipitated acute appendicitis. He underwent an appendectomy and healed well without complications.

A Case of Clostridium bifermentans Bacteremia in a Patient with Myelodysplastic Syndrome / 감염과화학요법

Cases of anaerobic bacteremia are rare, and the clinical impact of clostridial bacteremia remains to be clarified. Previous clinical reports have suggested that C. bifermentans is less virulent than other Clostridia species. This microorganism has occasionally been reported to cause septic arthritis, necrotizing pneumonia with empyema, brain abscesses, endocarditis, and metastatic osteomyelitis. Herein, we report on a case of C. bifermentans bacteremia in a patient with myelodysplastic syndrome in South Korea.

Clinical Differences According to Genotype in Acute Viral Hepatitis A in Daejeon, Korea / 대한내과학회지

BACKGROUND/AIMS: Acute viral hepatitis A is a major health problem in Korea and the influx of genotype IIIA is thought to be one reason. We examined the differences in the clinical characteristics and laboratory findings of genotypes IA and IIIA in Daejeon. METHODS: From November 2009 to June 2010, 81 patients positive for IgM anti-HAV were enrolled prospectively. The hepatitis A was genotyped using real-time polymerase chain reaction. The clinical characteristics and laboratory results were compared on the basis of genotype. RESULTS: The mean patient age was 32.6 +/- 7.4 years. The mean hospitalization was 7.7 +/- 2.4 days. The patient occupation varied. Clinically, vomiting and diarrhea were relatively more prevalent in genotype IIIA than in IA. Abdominal pain and skin spots were relatively more prevalent in genotype IA than in IIIA. The hemoglobin, peak aspartate aminotransferase (AST) level, and C-reactive protein were statistically higher in genotype IIIA than in IA. The distributions of the peak AST, alanine aminotransferase (ALT) and total bilirubin values tended to be perched in genotype IIIA than in IA. The international normalized ratio (INR) tended to be slightly prolonged in genotype IIIA than in IA. CONCLUSIONS: Recently, genotype IIIA of acute viral hepatitis A has become prevalent in Daejeon. Hepatitis A genotype IIIA probably causes worse laboratory abnormalities than genotype IA.
