ABSTRACT
PURPOSE: There occurred an explosive outbreak of aseptic meningitis in Ulsan, in the year of 2002. In this study, we report clinical manifestations, laboratory data and causative viruses of the outbreak. METHODS: Were assessed 371 children with aseptic meningitis who were admitted to the Department of Pediatrics, Ulsan University Hospital in Ulsan between May and July, 2002. We reviewed the sex, age, clinical manifestations, peripheral blood examinations and CSF examinations of the patients. Virus isolation and serotype identification were performed by cell cultures of cerebrospinal fluid and stool. RESULTS: The ratio of males to females was 1.9:1. The majority of aseptic meningitis occurred in children between 1 and 5 years of age with a mean age of 6.8+/-5.1 years. The clinical manifestations was fever, headache, vomiting, and abdominal pain and 16.2% of the patients developed neck stiffness. The mean duration of fever was 3.2 days. The mean value of peripheral blood leukocytes was 10,355+/-4,800/mm3 and the mean value of CRP was 0.96+/-1.67 mg/dL. Initial CSF findings revealed leukocytes 212+/-385/mm3, protein 37.0+/-18.9 mg/dL and glucose 68.3+/-17.6 mg/dL. Viruses were isolated 67(18.1%) out of 371 patients and the serotypes were echovirus 6 in 10 cases, echovirus 9 in 15 cases, echovirus 11 in 4 cases, echovirus 13 in 18 cases, and unclassified enterovirus in 20 cases. CONCLUSION: Aseptic meningitis was prevalent in Ulsan, in the year of 2002. The clinical manifestations and the laboratory findings of the patients were compatible with those of previous reports. The causative viruses were echovirus 6, echovirus 9, echovirus 11, echovirus 13 and unclassified enterovirus.

The incidence of malaria in Korea is significantly on the rise since its reemergence in 1993 and no screening test that can prevent the infection has been available. Very low birth weight infants are especially susceptible to malaria infection due to transfusions from multiple donors. We report a case of transfusion transmitted Plasmodium vivax infection in a 120-day-old infant of a gestational age 24 weeks with birth weight of 700 gm who was successfully treated with hydroxychloroquine.

Epiploic appendages are small, 0.5-5 cm long, peritoneal pouches containing small vessels and fat, located on the serous surface of the colon, from the cecum to the rectosigmoid junction. Pathologic states are rare in these appendages, the most frequent being is infarction either due to torsion or spontaneous. As a result of subsequent inflammatory reaction, the condition has been termed primary epiploic appendagitis. The condition is manifested by localized abdominal pain, which is often mistaken for appendicitis or diverticulitis and is usually diagnosed at surgery. With the aid of comtemporary imaging modalities, however, the diagnosis of epiploic appendagitis need no longer hinge on the pathologic specimen but may be established by the clinician. As this disorder recently has been demonstrated to be predominantly self-limited, laparotomy is no longer considered necessary. Conservative management has been shown to be safe. We report a 5-year-old male patient with epiploic appendagitis who presented with acute abdominal pain.

PURPOSE: To evaluate the function of Trp-Lys-Tyr-Met-Val-D-Met (WKYMVm) in human neonatal monocytes. METHODS: The peptide, Trp-Lys-Tyr-Met-Val-D-Met (WKYMVm), was synthesized, purified, and prepared in the Peptide Library Support Facility at Pohang University of Science and Technology. Female Sprague-Dawley rats (200+/-10 g) were preinfected with S. aureus and treated with WKYMVm through femoral vein. At various time points, blood samples were obtained by puncture of femoral artery and the serum was plated on the nutrient agar plate. The number of viable bacteria was determined by counting the number of bacterial colonies. In addition, using S. aureus and C. albicans, we evaluated the bactericidal and fungicidal activities of neonatal monocytes, which were separated from umbilical cord blood by Ficoll gradient. RESULTS: The numbers of bacteria in the blood of WKYMVm-treated rats were rapidly decreased with time, as compared with those of the untreated rats. The peptide treatment enhanced the bactericidal activity in vivo within 10 minutes. In neonatal monocytes, WKYMVm stimulated the intracellular killing of S. aureus in a dose dependent manner, showing the maximum effect at 100 nM. WKYMVm stimulated the phagocytic and fungicidal activities against C. albicans in a dose dependent manner, with the maximum effect at the 100 nM. CONCLUSION: These results suggest that WKYMVm may be an effective agent against the neonatal infections.
