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.

PURPOSE: Skin allergies through type 1 and 4 hypersensitivity reactions are the most frequent manifestations of drug allergies. We had previously experienced a case of a nurse with cefotiam-induced contact urticaria syndrome. To aid in preventing the progression of drug-induced allergic disease in nurses, we conducted a survey of tertiary hospital nurses who were likely to have been exposed professionally to antibiotics. METHODS: All 539 staff nurses at a tertiary hospital were asked to respond to a questionnaire regarding antibiotic exposure. Of the 457 nurses (84.8%) who responded, 427 (79.2%) received a physical examination of the hands and 318 (59.0%) received skin prick tests with the beta-lactam antibiotics cefotiam, cefoperazone, ceftizoxime, flomoxef, piperacillin and penicillin G. RESULTS: A positive response to at least one of the antibiotics occurred in 8 (2.6%) of the 311 subjects included in the analysis and stages 1 and 2 contact urticaria syndrome were observed in 38 (8.9%) and 3 (0.7%) of 427 nurses, respectively. The frequencies of a positive antibiotic skin test (6.9 versus 1.3%, chi-square=7.15, P=0.018), stage 1 contact urticaria syndrome (14.4 versus 7.4%, chi-square=4.33, P=0.038) and drug allergy (15.3 versus 3.6%, chi-square=18.28, P=0.000) were higher in subjects with a positive skin allergy history than in those without. Allergic rhinitis (P=0.02, OR=3.86, CI=1.23-12.06), night cough (P=0.04, OR=3.12, CI=1.03-9.41) and food allergy (P=0.00, OR=9.90, CI=3.38-29.98) were significant risk factors for drug allergy. CONCLUSIONS: Antibiotic sensitization and drug allergy occurred more frequently in nurses with a positive skin allergy history. Atopy may be an important risk factor for drug allergy.

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 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.

BACKGROUND AND OBJECTIVES: Direct stenting (DS) has been shown to be safe and feasible, with demonstrable reductions in cost, procedural time and radiation exposure, and may also result in less vessel injury. The aim of this study was to compare the immediate and six month clinical and angiographic outcomes of direct stent (DS) with stent implantation implantation following balloon predilatation (conventional stenting, CS). SUBJECTS AND METHODS: Between July 2001 and June 2004, 266 patients (293 lesions) with angina pectoris were included in this study. Patients having lesion characteristics with excessive calcification, left main lesion, chronic total occlusion, severe proximal tortuosity and a bifurcated lesion were excluded. Follow up angiography was performed about six months after the initial procedure. RESULTS: Direct (73 lesions) and conventional stenting (220 lesions) were performed respectively. In the DS group, the minimal luminal diameter was larger (0.36+/-0.18 vs. 0.31+/-0.19 mm, p=0.036) and diameter stenosis lower than in the CS group (89.1+/-5.1 vs. 90.6+/-3.9%, p=0.026). However, no difference was found in the reference vessel diameter between the two groups. From the immediate angiographic results, the CS group showed a longer stent length than the DS group (18.84+/-5.61 vs. 16.16+/-3.67 mm, p=0.000), but the DS group had a higher balloon inflation pressure than the CS group (12.25+/-1.71 vs. 11.35+/-1.72 atm, p=0.000). However, no difference was found in the post-stent minimal luminal diameter, acute gain and angiographic success rates. Follow up angiography was performed in 68.6% (201/293) of lesions. The angiographic restenosis rate was similar between the two groups (DS, 19.6 vs. CS, 19.3%, p=0.966), as were the other angiographic findings. The rates of in-hospital and 6 month follow up major adverse cardiovascular events (MACE) were similar between the two groups. CONCLUSION: Direct stenting showed similar rates of angiographic restenosis as well as inhospital and 6 months MACE (death, myocardial infarction, target lesion revascularization, cerebrovascular accident) compared with conventional stenting.

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.

We report an unusual case of adult minimal change nephrotic syndrome relapsed after 15-year of complete remission. In this case, the disease had occurred to the patient for the first time when he was 52 years old; relatively high age, and had been remitted with steroid therapy. After 15 years of complete remission, he visited our hospital with the symptoms of the generalized edema and the pitting edema of both lower extremities that occurred 15 days ago. Massive proteinuria(15, 865 mg/day) and hypoalbuminemia(1.7 g/dL) were detected. The pathologic evaluation of the biopsied specimen of the kidney showed the global sclerosis in 19% of glomeruli in light microscopic finding and the fusion of epithelial foot processes in electron microscopic finding. He was treated with pulse steroid therapy (methylprednisolone 500 mg/day iv for 3 days) and then, with oral prednisolone (60 mg/day). Generalized edema and proteinuria disappeared after 14 days of treatment, and there has been no relapse ever since. Adult-onset minimal change nephrotic syndrome relapses within 4 years after complete remission in 90 % of relapsed patients. The relapse after more than 5 years of complete remission, like this case, is very rare, especially in the case of late-onset disease. However, the possibility of relapse of the minimal change nephrotic syndrome after several years of its remission should be considered constantly and the long-term follow-up more than 10 years may be needed.

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.

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.
