Abstract

A retrospective analysis of clinical findings in 23 patients with Y. pseudotuberculosis infection who visited Department of Pediatrics of Han Il Hospital from May, 1990 to June, 1992 was performed. 1)The most prevalent age group was 7 to 12 years (16 case:69.6) and male-to-female ratio was 1.1:1. 2) Monthly distribution showed a high frequency in April, May and June(22 cases:95.8%) 3)The common symptoms were fever(23 cases:100%), abdominal pain (18 cases:78.3%) vomiting (16 cases:69.6%), diarrhea (13 cases:56.7%), rash (13 cases:56.5%) and acute renal failure (6 cases:26.1%) in order of frequency, respectively. 4)The laboratory findings were anemia (17.4%), WBC>1x104/mm3(73.9%), ESR>20mm/hr(901.3%), CRP >3+(91.3%). Positive Widal test (13.0%), BUN>20mg/dl(26.1%) and creatinine>1.2mg/dl(26.1%). 5)The most common serotype was 4a (30.4%), followed by 4b, 5b, 2b, 2c, 5a, 1b, 1a, 6 in order of frequency. The results suggest that Yersinia Y. pseudotuberculosis infection is one of the important causes of fever, eruptive skin disease and acute renal failure in Korean children and further studies including epidemiology, pathogenesis, etc, are needed.
