Drug-induced thrombocytopenia and purpura have boon developed by many various agents. Rifampin and Pyrazinamide have been known as bactericidal antituberculous drugs, but, the above side effects have been a problem. Especially, hematologic side effects art fatal to patients occasionally. Rifampin-induced thrombocytopenia and purpura have been well known, also, pyrazinamide-induced thrombocytopenia have been reported. A new quilonone agent Ciprofloxacin, has been commonly used in clinics now, but it's side effects are not known well. So, we report a case of a 23-year-old female with thrombocytopenia and purpura after taking Rifampin, Pyrazinamide, and Ciprofloxacin as antituberculous agents.

Branchial cleft cysts and branchial anomalies develop from the branchial cleft apparatus that persists after fetal development. The most common anatomical site for the occurrence of branchial cleft cysts is in the cervical area, generally anterior to the sternomastoid muscle in the upper or middle portion of the neck. A mediastinal branchial cleft cyst is extremely rare and few cases have been reported. We report the case of branchial cleft cyst found in the anterior mediastinum with literature review.

PURPOSE: In this study, we attempted to analyze the effectiveness of the atopic dermatitis camp for primary school students in the Seoul area. METHODS: Seoul city's atopy camp 2010 was conducted 10 times from May 22nd to October 24th for primary school students at an atopy friendly school and their parents. A total of 374 atopic dermatitis patients participated in the camp and questionnaires for 363 were analyzed, except 11 participants who had left several questions unanswered. In a 3-month follow-up survey, 167 participants out of 374 responded to the mailing questionnaire to evaluate the efficiency of the camp. The response rate was 44.7%. RESULTS: Satisfaction with the educational program of the camp was higher for lower grade students than for higher grade students.(P<0.001) Before camp, higher grade students (P<0.001) or students with severe symptoms were more knowledgeable of atopic dermatitis.(P<0.01) After the camp, the higher the grade, the more the knowledge the student had about atopic dermatitis.(P<0.001) Three months after the camp, there was positive change in the lifestyle of atopic dermatitis patients.(P<0.001) CONCLUSION: Knowledge on atopic dermatitis increased and the lifestyle of atopic dermatitis patients was improved due to the camp. Consequently, Seoul city's atopy camp can be utilized as a method to improve the quality of life of atopic dermatitis patients and their family. And Seoul city's atopy camp is expected to be a model for atopy camps in other local communities.

PURPOSE: We studied the changes in antibiotic sensitivity to the causative organisms of urinary tract infection (UTI), in order to provide useful information on the choice of adequate drugs in the treatment of UTI. METHODS: We retrospectively analyzed the major causative organisms and their antibiotic sensitivities in 69 patients diagnosed with UTI in the Department of Pediatrics, Samsung Cheil Hospital from 2002 to 2003. RESULTS: The frequency of UTI was the highest in infants younger than 1 year of age (88.4 percent). The male to female ratio was 3.05: 1. Escherichia coli was the most frequent organism (78.3 percent), followed by Klebsiella (116 percent), Pseudomonas (2.9 percent), Proteus (2.9 percent), Enterobacter, Morganelle, and Enterococcus (1.4 percent) in descending order. Antibiotic sensitivity of gram negative organisms was above 90 percent against imipenem, amikacin, 80 percent against aztreonam, cefepime, ceftriaxone, 50-70 percent against gentamicin, trimethoprime-sulfamethoxazole (TMP/SMX), and 23 percent against ampicillin (23.4 percent). CONCLUSION: Antibiotict sensitivity of gram negative organisms was high to amikacin and third generation cephalosporins but low to ampicillin, gentamicin and TMP/SMX. The use of ampicillin or TMP/SMX, as the first choice of the empiric and prophylactic treatment for UTI, should be reconsidered and investigated further.

BACKGROUND/AIMS: Menetrier's disease is a poorly defined condition that is of unknown origin, characterized by giant folds in the stomach. The histologic features are foveolar hyperplasia and cystic dilatation of the gland. We presented the characteristic findings of Menetirer's disease in Korea with a review of literatures to understand the Menetirer's disease more precisely. METHODS: The sixteen cases of Menetrier's disease was reported in Korea. We analyzed their age, sex, symptoms, signs, laboratory findings and treatments, retrospectively. RESULTS: The average age was 46 years. There were 11 men and 4 women. The most common symptom was epigastric pain (94%). The most common sign were epigastric tenderness (69%) and pretibial pitting edema (63%). Patients were often associated with the hypoalbuminemia (73%). All patients showed hypertrophic folds on either gastrofiberscopy or upper gastrointestinal series. All patients showed foveolar hyperplasia histologically. Three patients were operated to control a massive upper gastrointesinal bleeding. Two patients were operated to control the intractable edema. Two patients were operated to exclude gastric malignancy. CONCLUSIONS: Menetrier's disease showed broad clinical features such as epigastric pain, hypoalbuminemia, massive hematemesis and mimicking gastric malignancy. The giant gastric folds and foveolar hyperplasia were the most commom and important findings in the Menetrier's disease.

6.JAK2 Loss Arising From Tumor-SpreadThrough-Air-Spaces (STAS) Promotes Tumor Progression by Suppressing CD8+ T Cells in Lung Adenocarcinoma:A Machine Learning Approach

Background:
Tumor spread through air spaces (STAS) is a recently discovered risk factor for lung adenocarcinoma (LUAD). The aim of this study was to investigate specific genetic alterations and anticancer immune responses related to STAS. By using a machine learning algorithm and drug screening in lung cancer cell lines, we analyzed the effect of Janus kinase 2 (JAK2) on the survival of patients with LUAD and possible drug candidates.
Methods:
This study included 566 patients with LUAD corresponding to clinicopathological and genetic data. For analyses of LUAD, we applied gene set enrichment analysis (GSEA), in silico cytometry, pathway network analysis, in vitro drug screening, and gradient boosting machine (GBM) analysis.
Results:
The patients with STAS had a shorter survival time than those without STAS (P < 0.001). We detected gene set-related downregulation of JAK2 associated with STAS using GSEA. Low JAK2 expression was related to poor prognosis and a low CD8+ T-cell fraction. In GBM, JAK2 showed improved survival prediction performance when it was added to other parameters (T stage, N stage, lymphovascular invasion, pleural invasion, tumor size). In drug screening, mirin, CCT007093, dihydroretenone, and ABT737 suppressed the growth of lung cancer cell lines with low JAK2 expression.
Conclusion
In LUAD, low JAK2 expression linked to the presence of STAS might serve as an unfavorable prognostic factor. A relationship between JAK2 and CD8+ T cells suggests that STAS is indirectly related to the anticancer immune response. These results may contribute to the design of future experimental research and drug development programs for LUAD with STAS.
