Purpura fulminans is a potentially disabling and life-threatening disorder characterized by acute onset of progressive cutaneous hemorrhage and necrosis on distal extremities, and disseminated intravascular coagulopathy. We experienced a case of purpura fulminans due to Streptococcus pneumoniae. A 42-year-old women presented with skin petechiae, ecchymosis and gangrene on distal extremities with laboratory evidence of DIC. The latex agglutination test with CSF was positive at Streptococcus pneumoniae. To our knowledge, this is the first report of purpura fulminans caused by Streptococcus pneumoniae in Korea.

The successful cardiac transplantation depends partly on the donor heart preservation by a solution that will ensure recovery of myocardial function. The purpose of this study was to perform the evaluation of various preservation solutions and to accumulate the data on the requisites for ideal preservation solution. The experimental setup was the constant pressure Langendorff's perfusion system. Isolated rabbit hearts were perfused for 20minutes with warm Krebs-Henseleit solution, stored for 4 hours in cold preservation solution after cardioplegia, and then were reperfused for 20minutes. The 4 experimental groups were prepared : Hartmann's solution group (group I, control), modified Euro-collins' solution group (group II, MEC), modified University of Wisconsin group (group III , MUW), and CK solution(made by the author) group (group IV, CK). The parameters for assessing the preservation ability were levels of enzymes in freezed myocardial tissues (lactate, creatine kinase-MB and adenosine deaminase), coronary flow, left ventricular developing pressure and dp/dt. In conclusion, the ability of preservation for isolated rabbit heart was excellent in CK solution and modified University of Wisconsin solution, and poor in modified Euro-collins' solution, compared with Hartmann solution. CK solution has low potassium concentrations(34.2mEq/L) and includes various substrates to be salutary on myocardial preservation. This fact may indicates the necessity of further refinements in selection or composition of electrolytes and substrates.

OBJECTIVES: To suggest direction for improving policies by understanding current management of narcotics or psychotropic drugs and analyzing their distributions and usage. METHOD: We conducted a comparison analysis between health insurance claims and the amount supplied to health care institutions for narcotics or psychotropic drugs through health insurance claims data and drug distribution supply data from 2010 to 2012 collected from Korea Pharmaceutical Information Service Center (KPIS). Furthermore, we carried out literature investigation and online search to comprehend the current management of narcotics drugs in Korea. RESULTS: The amount supplied to medical institutions for all drugs in 2012 was 19.4 trillion won, which increased from 19.5 trillion in 2011 by 0.54%. For narcotic drugs, the amount supplied was 318.4 billion won in 2011 and increased to 335.1 billion won by 5.3% in 2012, which exceeded the rate of increase for the amount supplied for all drugs. The proportion of amount claimed in the total amount supplied to medical institutions for all drugs was 60.5% in 2012, whereas the proportion of amount claimed for narcotic drugs was 55.6%, which showed that narcotic drugs were used relatively less within health insurance. Furthermore, management of the current domestic distribution supply data focuses on manufacturing and medical institution supply stages. CONCLUSION: Hereafter, the management of narcotics or psychotropic drugs needs to be improved by reinforcing active monitoring in optimal prescription and usage in patients by collecting and analyzing information on drug usage of patients.

Transforming growth factor-B1 (TGF-B1) is well known to be one of the most potent Immunosuppressive cytokines. To determine whether TGF-B1 secreted in the latent form can be immunoregulatory, TGF-B1 cDNA driven by the human -actin promotor was transfected into a murine thymoma cell line, EL4 cells. The transfectants (ELJ4) secreted a latent torm of TGF-B1 at a concentration of 5 ng/ml under the influence of TPA. Transfected TGF-b1 transcripts was readily detected by RT-PCR in ELJ4 cells regardless of the presence of TPA, but not in EL4 cells. In addition, we found the degree of Thy-B1 expression, IL-2 secretion and the proliferation rate are not altered by the transfection. Finally, EL4 and ELJ4 cells were injected into C57BU6 mice (syngenic strain), subcutaneously. Tumor cell masses derived from both cell populations survived longer than 1 wk, and the size of tumor derived from ELJ4 was three times larger (2.5 cm of diameter) than that from EL4. Virtually, there was no histopathological difference between two tumors. Taken together, the results from the present study indicates that EL4 thymomas transfected with TGF-1 secretes a latent form of TGF-B1 which may suppress host immune defence system.

BACKGROUND: The aim of the study was to establish a new syphilis test algorithm using Architect Syphilis TP (Abbott Japan, Japan: AST), a fully automated treponemal antibody test, as a screening test in a university hospital laboratory. We evaluated performance characteristics of AST in various patient groups. METHODS: A total of 1,357 serum samples obtained from patients at a university hospital from June to August, 2008 were categorized into checkup, preoperative, other diseases, diagnosis (clinically suspected of syphilis), and follow up groups. We compared the results of AST with those of RPR (N=1,276) or Treponema pallidum hemagglutination assay (TPHA, N=81). Samples with discrepant results between RPR or TPHA and AST were retested by fluorescent treponemal antibody absorption test (FTA-ABS) and all patients' clinical records were thoroughly reviewed. RESULTS: The positive rate of AST was significantly higher than that of RPR in preoperative and other diseases groups and was the same as that of RPR in diagnosis group. There were no significant differences in check up and follow up groups. The results of AST showed 97.4% (1,243/1,276) and 97.5% (79/81) concordance rates with those of RPR and TPHA, respectively. Among 26 RPR-AST discrepant and FTA-ABS confirmed cases, there were 20 RPR false-negatives, 4 RPR false-positives, 1 AST false-negative, and 1 AST false-positive. CONCLUSIONS: Based on the results and literature review, we established a new syphilis test algorithm using AST as a screening test, which would be helpful for detection of more syphilis patients including latent infections.

Klippel-Trenaunay-Weber syndrome is a rare sporadically occurring congenital soft tissue anomaly characterized by cutaneous hemangiomata, hemihypertrophy and occasionally arteriovenous malformations(AVMs). No definite genetic defect has been identified. The appearance is a soft tissue mass of an extremity, usually affecting the adjacent trunk, hydrops fetalis, ascites, abdominal hemangiomatous masses, and hepatomegaly. When diagnosed prenatally, the disorder may be severe. Thrombocytopenia due to platelet consumption within the hemangioma and high output cardiac failure may complicate the outcome. Termination of pregnancy can be offered in severe forms, otherwise no alteration of management in expected. The management of newborns is primarily nonoperative, but some may benefit from surgical intervention. We report a case of Klippel-Trenaunay-Weber syndrome diagnosed prenatally by ultrasonogram in the second trimester and subsequently was terminated, with a brief review of literature.

TGF-beta1 is well known to induce Ig germ-line alpha (GLalpha) transcription and subsequent IgA isotype class switching recombination (CSR). Homeodomain protein TG-interacting factor (TGIF) and E3-ubiquitin ligases TGIF interacting ubiquitin ligase 1 (Tiul1) are implicated in the negative regulation of TGF-beta signaling. In the present study, we investigated the roles of Tiul1 and TGIF in TGFbeta1-induced IgA CSR. We found that over-expression of Tiul1 decreased TGFbeta1-induced GLalpha promoter activity and strengthened the inhibitory effect of Smad7 on the promoter activity. Likewise, overexpression of TGIF also diminished GLalpha promoter activity and further strengthened the inhibitory effect of Tiul1, suggesting that Tiul1 and TGIF can down-regulate TGFbeta1-induced GLalpha expression. In parallel, overexpression of Tiul1 decreased the expression of endogenous IgA CSR-predicitive transcripts (GLT(alpha), PST(alpha), and CT(alpha)) and TGFbeta1-induced IgA secretion, but not GLT(gamma3) and IgG3 secretion. Here, over-expressed TGIF further strengthened the inhibitory effect of Tiul1. These results suggest that Tiul1 and TGIF act as negatively regulators in TGFbeta1-induced IgA isotype expression.

BACKGROUND: The number of patients suffering from acute myocardial infarction is on the increase in Korea due to the westernization of life style. Recent improvement of therapeutic stratigies have shown early mortality benefits in acute myocardial infarction. But we don't have data how many patients died and what's the cause of death in these patients. This study aimed to find out the mortality rate, cause of death and it's relevant prognostic factors of myocardial infarction (MI) patients who admitted alive, and to construct a database which will be used to develop a risk stratification strategy for the implementation of new preventive therapeutic modalities, such as implantable cardioverter-defibrillator (ICD). METHODS: Seven hundred and forty two MI patients admitted to our hospital from March, 1999 to August, 2002 were included in this study. The risk factors and survivals were evaluated by medical record searching and telephone survey in these patients. RESULTS: The average age was 64 years-old and 67% was male. During the mean follow up 20.7+/-15.4 months, total 105 cardiac death (14.2%) was occurred and cumulative mortality rate at 1 year and 2 year was 5.69% and 10.80%, respectively. Of the total 129 death, in-hospital death was 68 (cardiac death 48, non-cardiac death 20) and out of hospital death was 60 (cardiac death 57, non-cardiac death 4). When it comes to cause of death, most common cause of cardiac death was malignant arrhythmia. The proportion of malignant arrhythmia in cardiac death was 81.3% and 72% of in-hospital and out of hospital death, respectively. Multivariate analysis showed that old age, low LV ejection fraction and no percutaneous coronary intervention (PCI) treatment were independent risk factors for cardiac mortality. CONCLUSIONS: Myocardial infarction shows still high mortality rate despite the recent development of therapeutic strategy. As post-MI patients with low LVEF or no PCI shows high mortality, the early reperfusion therapy should be encouraged. Additionally, because malignant arrhythmia was one of the most in cause of cardiac death, ICD therapy to prevent sudden cardiac death should be considered in an active manner.

This is pilot study to evaluate the relationship of physical fitness with age, body fat, work pattern and life style among 20-9 aged male workers (n=417). Physical fitness was measured by maximum oxygen uptake, forced vital capacity, 1 second forced expiratory volume, grip strength, back strength, sit ups and trunk flexion. Life style was self-reported on a questionnaire about regular exercise, smoking, alcohol consumption, coffee consumption, degree of stress, and percent of body fat measured by bioelectrical impedance fat meter. Age was significantly and negatively related to physical fitness except grip strength. Obesity was next to most significant factor for physical fitness, it was associated with maximum oxygen uptake, grip strength, back strength, trunk flexion. Regular exercise was associated with maximum oxygen uptake. Others was insignificantly related to physical fitness. Performance of physical fitness test was significantly correlated with age, obesity and regular exercise.
