Epithelioid sarcoma is malignant tumor described by Enzinger, that is likely to be confused with a varety of benign and malignant conditions, especially a granulomatous process, a synovial sarcoma Or an ulerating squamous cell carcinoma. The tumor occurs chiefly in young adult and most commonly affects the soft tissue of the hand, the forearm and the pretibial region. The tumor is characteristically a slowly growing lesion but frequent recurrence is common and metastasis were most frequent in the lung. In this paper, we reported one case which is believed to be epithelioid sarcoma in the forearm.

The effects of flumazenil, a benzodiazepine antagonist were evaluated in a clinical study in which midazolam (0.1 mg/kg) was used as a sedative agent during the spinal anesthesia. Sixty patient were divided into two groups as group F (n=30) and group S (n=30). Flumazenil 0.3 mg (3 mL) in group F and saline 3 mL in group S were administered at the end of surgery. Blood pressure, pulse rate, respiratory rate and oxygen saturation (SaO2) were checked just before and at, 5, 15, 30, 60 and 120 minutes after the administration of flumazenil or saline. Also we evaluated the level of conciousness and orientation in time and space. The results were as follows; 1) Changes in blood pressure, pulse rate and respiratory rate were not different between two groups, exeept SaO2 was which increased significantly in the flumazenil group. 2) The flumazenil group revealed improved level of consciousness and orientation in time and space which began 5 minutes after flumazenil and was maintained 30 minutes thereafter. 3) We could not observe the any side effects of flumazenil.

PURPOSE: To determine whether the delivery of the SV40 large T-antigen is a feasible method for transiently inducing proliferation of corneal endothelial cells, we delivered liposome-protein complex into bovine corneal endothelial cells(BCEC). METHOD: SV40 large T-antigen protein was introduced into BCEC and positive cells were identified by immunohistochemistry. Quiescent BCECs were double-labeled using BrdU as a measure of de novo DNA synthesis and the Ki-67 was detected by standard immunohistochemical methods. RESULT: The treatment of quiescent BCECs with large T antigen caused an increase in BrdU incorporation and Ki-67 expression. It was tested by time-course study. CONCLUSION: This finding suggests that liposome-mediated delivery of transforming proteins could be a method to transiently induce corneal endothelial cell proliferation.

PURPOSE: Pediatric sedation is an important factor for obtaining the images of good quality. We performed this study to analyze the efficacy of our sedation protocol using chloral hydrate. MATERIALS AND METHODS: We collected prospectively 151 sedation records of children(1 day-15 years old), who were sedated with chloral hydrate for MR(n=112) or CT(n=39) studies. We initially administered 50mg/Kg orally(n=94) or rectally(n=57) 30 minutes before the scheduled examinations, and then administered additionali dose (second dose :25-35mg/Kg, third dose:10-15mg/Kg) to patients whom initial dose failed to sedate. RESULTS: Satisfactory sedation was achieved by initial administration in 109 patients(72%) without si difference between oral(per oral: P.O.) and rectal(per rectal: P.R.) administration. Second dose was required in 28% and third dose in 5%. MR and CT examinations required second dose in 36(32%) and 6 patients(15%), respectively. P.O. -patients vomited in 5%. P.R. -patients defecated in 22% after initial administration. There were no other serious complications. Time interval from the drug administration to the start of examinations was 33 minutes in initial-dose-group and 64 minutes in additional-dose-group. Two patients could not complete MR examination due to early arousal. Prolonged sedation, requiring more than 30 minutes for alertness after MR and CT examinations, was encountered in twenty(18%) and two patients(5%), respectively. CONCLUSION: Our protocol using chloral hydrate(P.O. or P.R.) is thought to be an effective and safe method for pediatric sedation for MR or CT imaging.

PURPOSE: There has been little research regarding the effectiveness of oseltamivir for influenza B infections. We sought to identify the different clinical manifestations between patients treated with and without oseltamivir. METHODS: We retrospectively studied the medical records of 72 inpatients or outpatients from two medical centers diagnosed with influenza B infections by either a rapid antigen test or multiplex reverse transcriptase PCR between January 2012 and July 2012. We compared gender, age, past medical history, admission period, total fever duration, fever duration after hospitalization, post-oseltamivir medication peak temperature, laboratory test, chest X-ray, antibiotic medication, and the presence of concomitant viral or bacterial infections. RESULTS: The number of subjects in our study was 72 who were diagnosed with influenza B pneumonia, acute bronchitis, acute bronchiolitis, croup, and mean age was 3.6+/-2.8 year old. The demographic characteristics and clinical manifestations of oseltamivir and the non-oseltamivir groups, including hospitalization period (4.18+/-2.10 vs 4.79+/-1.49 days, P=.17) and total fever duration (5.32+/-2.07 vs 6.41+/-3.25 days, P=.09), demonstrated no significant differences. Notably, the oseltamivir group did have significantly reduced usage of antibiotic treatment than the non-oseltamivir group (P=.04). When we limited our patient group to patients under the age of three, similar results were seen. The group prescribed oseltamivir within 48 hours of fever onset had less antibiotic usage, in addition to a shorter fever duration. CONCLUSION: Oseltamivir appeared to have no benefit in improving the clinical course. However, if it is prescribed within the first 48 hours of symptoms, it may be more effective.

BACKGROUND: Previous reports have suggested that alleles at the plasminogen activator inhibitor-1 (PAI-1) gene are associated with increased risk of developing coronary artery disease, including myocardial infarction and stroke through their effect on PAI-1 levels. Method: We attempted to search English literatures for all reports of possible effects of PAI-1 gene on cardiovascular disease in human published prior to November 1998. We used a Mantel-Haenszel method (fixed effect model) and random effect model, respectively, to perform a meta-analysis of 7 case-control studies that provided information related to the effects of PAI-1 gene on risk of cardiovascular disease. RESULTS: From 7 studies for diagnosed cardiovascular disease, the relative frequencies of the three genotypes among controls was (5G/5G) (homozygous normal), 24.5%; (4G/5G) (heterozygous), 48.2%, and (4G/4G) (homozygous for the mutant, 675 GGGG), 27.3%. These relative frequencies in cases were 21.7% for 5G/5G, 48.0% for 4G/5G, and 30.3% for 4G/4G. In fixed effect model, compared with those with genotype (5G/5G), the overall odds ratio (OR) for cardiovascular disease among those with (4G/5G) was 1.12 (95% CI, 0.93 to 1.34), and it was 1.20 (1.01 to 1.44) for the (4G/4G) genotype. For five studies with myocardial infarction as the outcome, the overall OR of myocardial infarction was 1.20 (0.99 to 1.47) for those with (4G/5G) and 1.24 (1.00, 1.54) for those with (4G/4G) genotypes, respectively. CONCLUSION: Our findings provide support for the weak association between PAI-1 gene and cardiovascular disease, in particular, myocardial infarction.

The N-terminal sequence of HIV1 gp41 (amino acid residues 584-623) was known to be the immundominant region of HIV1 gp41 protein. In order to determine epitope for gp41 protein of Korean anti-HIV1 positive sera, multiple antigenic peptides (MAPs) for the sequences corresponding to 584-604, 590-612, 604-623 and 584-618 of HIV1 gp41 were synthesized by solid phase method using Fmoc-Lys (Fmoc)-OH and used as coating antigens for ELISA. The reactivities of the synthetic peptides with Korean HIV1 positive (21 samples) and anti-HIV1 negative sera (22 samples) obtained from healthy blood doner were estimated by an indirect ELISA. MAPs for 584-604, 590-612 and 604-623 of gp41 reacted with 62 %, 100 % and 81 % of Korean anti-HIV1 positive sera tested, respectively. The results suggest that the epitope for HIV1 gp 41 for Korean anti-HIV1 positive sera is located in the region of amino acid 590-612 of gp41. MAP for gp41 (584-618) reacted with all (100 %) of anti-HIV1 positive sera tested, but did not react with anti-HlV1 negative sera. In addition, this MAP reacted stronger with seven samples of anti-HIV1 positive sera of anti-HIV1/2 combo performance panel than the mixture of 584-604, 590-612 and 604-623 of gp41, but did not react with anti-HIV negative serum. The high sensitivity and selectivity of MAP of gp41 (584-618) suggest that this peptide as a coating antigen in an ELISA system will be useful for antibody detection of HIV1.
