BACKGROUND: Intussuseception is one of the most common diseases requiring abdominal emergency care in early childhood. The delay in diagnosis increases morbidity and, in particular, reduces the success rate of the non-surgical method of reduction. In this report, the authors determined the clinical characteristics of pediatric patients with intussusception, and the factors involved in delayed diagnosis and the efficacy of doppler ultrasonography in diagnosis. METHODS: The authors performed a retrospective study of 44 cases in 42 patients with intussusception who had visited the emergency room of SamSung medical center from January 1st to December 31, 1996. RESULTS: The sex ratio was equal and 64.3% of the patients were under 1 year of age. The prevalent complaints were vomiting(36.4%) and abdominal pain(33.8%). Ultrasonography was used in 11 cases, 3 of them were performed because of obscure symptoms and the rest were due to diagnostic delay. The average time past from visit to diagnosis was 4 hours and 20 minutes, and there were 4 diagnostic delays. Air enema reductions were unsucessful in 11 cases(25%) and that was related to hospital-visit delays and long time past from symptom onset to diagnosis. There were no motalities. CONCLUSION: To reduce delays in diagnosis and unnecessary operations, the use of doppler ultrasonography is recommanded in suspicious cases. And to reduce the hospital-visit delays, related to the failure on non-surgical reduction, the education about this disease is necessary.

PURPOSE: The correlation between sonographic findings and clinical symptoms was investigated in the patients with mesenteric lymphadenitis who had recurrent acute abdomen. MATERIALS AND METHODS: Seventy-eight children with recurrent acute abdominal pain without obvious primary disease were evaluated by sonography. The initial and follow-up sonography were performed in 17 children. The abdomen was divided into 3 areas. The number and size of mesenteric lymph nodes were observed in each zone, and was compared with the clinical findings. RESULTS: In 56(71.8%) of 78 cases, good correlation was seen in the area of the greatest size and number of the lymph nodes in the sonography. Most severe symptom, was seen in the right lumbar area(49 cases) and umbilical area(7 cases). In 17 cases of follow up, 14 cases showed decrease size and number of mesenteric lymph nodes while 2 cases showed increase in size and number of the nodes with aggravated symptoms. CONCLUSIONS: Ultrasonography was useful to detect and localize the enlarged mesenteric lymph nodes. Initial and follow-up sonography showed good correlation between the changes in number and size of the lymph nodes and symptoms.

This study was conducted to evaluate the association of job characteristics and stress indicators, from May 1st to 10th, 1996. The study population was 210 workers (clerical workers, 67; engineers, 82; assembly line workers, 61) engaged in a television manufacturing company. A questionnaire method was used to collect the data regarding to job demand, job control, behavioral type, life style and psychiatric symptoms. Clinical examination was conducted to measure blood pressure, serum cholesterol, fasting blood sugar and HbA1c. Percentage of high subjective job strain group was significantly higher in clerical workers(9.0 %) than in engineers(4.9 %) and in assembly line workers(3.3 %) (p < 0.01). Mean values of fasting blood sugar and HbA1c were significantly different between types of occupation and were the highest in clerical workers (p < 0.05). Significant association was found between perceived job characteristics and psychiatric symptom score (p < 0.01). The more job demand and the less job control was, the higher psychiatric symptom score was reported. Diastolic blood pressure was significantly related to job control (p < 0.05). The more job control was, the higher blood pressure was reported. In multiple regression analysis, job demand, job control and age were significant variables explaining the psychiatric symptoms and R2 was 0.23. Perceived job characteristics and type of occupation were not significant in explaining diastolic blood pressure and cholesterol. Type of occupation, job demand, age and BMI were significant variables explaining lasting blood sugar and R2 was 0.25. Type of occupation was the only significant variable explaining HbA1c and R2 was 0.07. According to this result, occupational type and subjective job characteristics must be considered in study of job stress. As a result of multiple analysis, subjective job characterics are significantly related to psychiatric symptoms and type of occupation is significantly related to fasting blood sugar and HbA1c.

PURPOSE: The purpose of this study was to describe the clinical characteristics of neonatal urinary tract infection (UTI) caused by Klebsiella pneumoniae and non- Klebsiella pneumoniae UTI. METHODS: We compared clinical characteristics of 84 neonatal patients with UTI caused by Klebsiella pneumoniae who were hospitalized at the Department of Pediatricsat Han Dong University, Sunlin Hospital during the period between May, 1994 and August, 1998. The cases were divided into two groups depending upon causative organisms' Klebsiella pneumoniae UTI vs non-Klebsiella pneumoniae UTI, and the clinical characteristics of these groups were compared. RESULTS: Escherichia coli was the most common bacterial pathogen causing neonatal UTI, followed by Klebsiella pneumoniae. There was no significant difference in the sex distribution of Klebsiella pneumoniae UTI, but non-Klebsiella pneumoniae UTI showed male predominence. There were no significant differences in the incidences of hematologic, urologic, radiologic findings and perinatal complications in between these 2 groups. CONCLUSION: Klebsiella pneumoniae is the second most common pathogen causing neonatal UTI. There were no specific differences in the laboratory, symptomatologic, and radiologic findings in these two groups.

We present here, a case of pemphigus erythematosus developed in a 31-year-old woman, who had been suffering from repeated episode, of remission and exacerbation with several erythematous, and somewhat oozing patche accompanying a mild pruritus or her face, upper part of the back and anterior chest. In serological studies, she had antinuclear antiboc@lies at. a titer of 1:160. Histopathological finding showed subcorneal bullae. Immunofluorescent study revealed IgG and C, deposition in the intercellular space of the epidermis and along the de rmoepidermal junction.

BACKGROUND: Coagulase negative staphylococcus (CNS) spp. is a major pathogenic organism of nosocomial and community-acquired urianry tract infections, and causes infrctions in the immunocompromised host, and in particular, bloodstream infetions in patent with indwelling devices. High prevalance of methicillin resistance has been noticed in CNS which also have been recongnized as an important multidrug resistant pathogen. The optimal phenotypic method for detecting methicillin resistance still remains controversial, and new guidelines for detecting methicillin resistance of CNS was proposed by NCCLS in January 1999. We evaluated the relationship between mecA gene by PCR method and antimicrobial susceptibility tests according to the new NCCLS guidelines. METHODS: A total of 82 CNS isolates were examined for MICs and penicillin MICs by disk diffusion and agar dilution method according to NCCLS guidelines, and detections, and detection of mecA gene by PCR. RESULT: In disk diffusion method, 66 strains (80.5%) and 63 strains (76.8%) showed resistance to penicillin and oxacillin, respectively, and in agar dilution method, 71 strains(86.6%) and 53 strains (64.6%), respectively. In PCR method, mecA genes were detected in 49 strains(59.8%). Comparing with mecA gene detection by PCR method, the sensitivity of disk diffusion and agar dilution method was 95.8% and 89.8%, repectively. However, the sensitivity of disk diffusion and agar dilution method was 65.3% and 75.5%, respectively using previous NCCLS criteria. CONCLUSION: The new criteria of NCCLS detects the methicillin resistance induced by mecA gene more sensitively than previous one.
