A clinical study was made on 71cases of Mycoplasma Pneumoniae Pneumonia from March, 86 to February, 89. The results were as follows; 1. Among the 315 cases of pneumonia, the incidence of mycoplasma infection was 22.5% 2. The peak incidence of age was between 5 to 9years of age (53.5%) 3. The sex ratio of male to female was 1.3:1 4. Monthly distribution showed relatively high frequency from October to January (59.2%) 5. Most common clinical symptoms were cough (98.6%) and then followed by fever (49.3%), coryza (19.7%). Rales were the most common finding (95.7%) and followed by pharyngeal injection (49.3%) and wheezing (18.3%) 6. The leukocyte counts in peripheral blood were most common in the range of 5000-10000/mm³ (47.9%) and the ESR was increased in 57.7%, and positive CRP cases were 87.3% 7. The most common radiologic finding of pulmonary infiltration was interstitial infiltration (45.1%) and then followed by disseminated lobular (39.4%) and lobar pneumonia (15.5%) 8. There are a few cases associated disease or complication: otitis media (5.6%), hepatitis (4.2%) acute glomerulonephritis, bronchial asthma and sinusitis (2.8%), thrombocytopenia (1.4%)

PURPOSE: Henoch-Schonlein purpura nephritis(HSPN) accompanied by nephrotic syndrome(NS) is known to have a poor prognosis and effective treatment is still controversial, even though both corticosteroids and immunosuppresant have been used for therapy. Cyclosporine A(CsA) is a well known immunosuppresant and widely used in renal transplantation and glomerular diseases especially steroid resistant. The aims of this study was to evaluate the therapeutic effect of CsA and to compare CsA with previously reported our data of rifampin(RFP) and azathioprine(AZA) in children with HSPN accompanied by NS. METHODS: 37 HSPN patients with NS confirmed by renal biopsy were selected. Of these, 17 patients were treated with CsA(5 mg/kg/day) for 6-8 months, 7 children were treated with RFP(10-20 mg/kg/day) for 9-12 months and 13 patients were treated with AZA(2 mg/kg/day) for 8 months. Along with these regimens, low dose oral prednisolone(0.5-1 mg/kg, qod) was also used. Sequential renal biopsy was done in all patients 1 month after termination of treatment. RESULTS: Complete remission rate of nephrotic syndrome was 5S.8% in CsA, 57.1% in RFP and 38.4% in AZA group after 17, 22, 11 months of mean follow-up period. Overall remission rate including partial remission was 88.2% in CsA, 85.7% in RFP and 84.6% in AZA group. Disappearance rate of hematuria was 58.8% in CsA, 57.1% in RFP and 46.2% in AZA group. Improvement of grade of clinical status was observed in 17 out of 17 CsA, 7 out of 7 RFP and 10 out of 13 AZA group. Improvement of pathologic class on sequencial renal biopsy was shown in 5 CsA(29.4%), none RFP(0%) and 2 AZA group(12.4%). Improvement on histologic immune-deposition was seen in 15 CsA(88.2%), 6 RFP(85.9%) and 4 AZA group(30.8%). CONCLUSION: In conclusion, Both CsA and RFP treated groups showed better result in complete remission rate of nephrotic syndrome and significant inprovement of histologic immune-deposition compared with AZA treated group(p=0.004). So, we recommend CsA and RFP rather than AZA for immunosuppresant treatment in HSPN with nephrotic syndrome.

Tumorlet is a rare lesion of disputed origin that was first described by whitwell in 1955, and about one-third of the reported cases have been associated with underlying lung disease. Patient was a 60-year-old female who was admitted with a histroy of chest discomfort and dyspnea. Right lower lobe was partially resected under the clinical diagnosis of the bronchogenic cyst. Grossly, lung tissue around round cystic lesion appeared brown firm and somewhat fibrotic, and showed several scattered ill-defined whitish gray nodules. Microscopically, lung tissue around bronchogenic cyst was partially obliterated by dense fibrous scar tissue. Within this areas of fibrosis, and in the wall of alveolar ducts and respiratory bronchioles, innumerable microscopic tumorlets were found and argyrophilic granules were also demonstrated in scattered tumorlets with Grimelius stain.

Sarcomatoid carcinomas are malignant epithelial neoplasms in which the tumor cells assume a partial or complete spindle cell pattern of growth, leading to the erroneous classification of some true carcinomas as sarcomas. These spindle cells are malignant and manifest various amount of both vimentin and cytokeratin. Positive reaction of some of the spindle cells for cytokeratin antibodies is confirmatory. Clinical features do not differ significantly from those of patients with high-grade transitional cell carcinoma. So far, 13 cases of sarcomatoid transitional cell carcinoma of the renal pelvis have been reported in English and Korean literature. In this report, we describe clinicopathologic features of recently observed two cases of sarcomatoid transitional cell carcinoma of the renal pelvis and summarize the pathologic findings of previously reported cases with review of the literature.

Analysis and prediction of the care charges related to colorectal cancer in Korea are important for the allocation of medical resources and the establishment of medical policies because the incidence and the hospital charges for colorectal cancer are rapidly increasing. But the previous studies based on statistical analysis to predictthe hospital charges for patients did not show satisfactory results. Recently, data mining emerges as a new technique to extract knowledge from the huge and diverse medical data. Thus, we built models using data mining techniques to predict hospital charge for the patients. A total of 1,022 admission records with 154 variables of 492 patients were used to build prediction models who had been treated from 1999 to 2002 in the Kyung Hee University Hospital. We built an artificial neural network (ANN) model and a classification and regression tree (CART) model, and compared their prediction accuracy. Linear correlation coefficients were high in both models and the mean absolute errors were similar. But ANN models showed a better linear correlation than CART model (0.813 vs. 0.713 for the hospital charge paid by insurance and 0.746 vs. 0.720 for the hospital charge paid by patients). We suggest that ANN model has a better performance to predict charges of colorectal cancer patients.

Arteriovenous malformation of the uterus is rarely encountered. It is potentially lethal because of profuse, uncontrollable bleeding at the time of diagnostic dilatation and curettage. To our knowledge, only 38 cases of localized uterine arteriovenous malformation have been reported in English and Korean literature. Recently we experienced a case of uterine arteriovenous malformation in a 28-year-old multiparous woman. Under the clinical impression of uterine tumors or arteriovenous malformation, a total hysterectomy was done. Gross examination demonstrated a vascular nature of the mass in the posterior wall of the fundus. Microscopically, there was an ill-defined mass composed of numerous irregular, anastomosing large vessels with various diameters.

Sixty-three patients with permanent sigmoid colostomy were surveyed to evaluate their satisfaction and complications with the "irrigation technique" and the "atural evacuation" of the colostomy management (irrigation technique; 32 patients, natural evacuation; 31 patients). All patients had colostomy for at least 12 months without disease recurrence. Each patient was interviewed in addition to standard questionnaire. The irrigation was not associated with any major complication including colonic perforation. The irrigation was used younger age group than the natural evacuation (53+/-10 vs. 62+/-12, P=0.01). The frequency of bowel movement was lower in the irrigation than in the natural evacuation (5.1+/-2.5/wk vs. 10.8+/-9.0/wk, P=0.04). Five patients (16%) of the irrigation experienced spontaneous bowel action but only one patient suffered from it. The time spent for managing irrigation was 59+/-13 minutes. Twenty-three patients (74%) of the natural evacuation suffered from one or moreproblems such as expensive apparatus, leakage, skin irritation or odor. Sixteen patients (52%) of the natural evacuation and 2 patients (6%) of the irrigation were restricted in social activity (P=0.0001). Thirteen patients (42%) of the natural evacuation and 1 patient (3%) of the irrigation were dissatisfied with colostomy management (P=0.002). Thus, the irrigation technique seems to be more effective and satisfactory method for managing colostomy without compromising patient's social activity when it is performed in appropriately selected patients.
