The case is presented a 49-year-old man had several year history with chronic renal failure with hyperlipidemia due to diabetes mellitus. Treatment of hyperlipidemia was started by oral bezafibrate intake 600 mg per day. Several days later, patient noticed muscle weakness and myalgia. The serum CK, LDH, AST levels were remarkably elevated, myoglobulinuria was also noticed The symptoms of the patient were resolved after the drug was discontinued, thus the diagnosis was established as having bezafibrate induced rhabdomyolysis. On the basis of the above description, bezafibrate may induce muscle damage if dose is excess over the renal capacity. Extreme caution is warranted when the patient is placed on bezafibrate and has renal dysfunction.Strict dose adjustment is necessary in taking account of renal function to avoid muscle damage including rhabdomyolysis.

OBJECTIVE: To assess the reliability of triple marker screening test in midtrimester pregnancy for fetal Down syndrome. METHODS: From October 1, 1996 to May 31, 1998 at Nowon Eulji Hospital, 3700 Pregnant women underwent serum tiple marker screening for Down syndrome during 15-20weeks of gestational age. The results of serum triple marker screenig tests for Down syndrome and the outcomes of pregnancies were retrospectively assesed. RESULTS: Sixty seven of 3700 cases(1.81%) were positive in screening test, and 3633(98.18%) cases were negative. Among 67 cases of positive screening test, 1 case(1.49%) was diagnosed as Down syndrome. Among 3633 cases of negative screening test, 4 cases(0.1%) were diagnosed as chromosomal abnormalies postnatally. Two of these 4 cases of chromosomal abnormalies were Down syndrome. CONCLUSION: With this results, sensitivity of triple marker screeing test for Down syndrome is very low as 33.3%. In order to increase the sensitivity, some compensatory adjustment is required in triple marker screening test.

Proper seat belt use saves lives; however, the use rate decreased in Korea. This study aimed to measure the magnitude of the preventive effect of seat belt on case-fatality across drivers and passengers. We used the Emergency Department based Injury In-depth Surveillance (EDIIS) database from 17 EDs between 2011 and 2012. All of adult injured patients from road traffic injuries (RTI) in-vehicle of less than 10-seat van were eligible, excluding cases with unknown seat belt use and outcomes. Primary and secondary endpoints were in-hospital mortality and intracranial injury. We calculated adjusted odds ratios (AORs) of seat belt use and driving status for study outcomes adjusting for potential confounders. Among 23,698 eligible patients, 15,304 (64.6%) wore seat belts. Driver, middle aged (30-44 yr), male, daytime injured patients were more likely to use seat belts (all P < 0.001). In terms of clinical outcome, no seat belt group had higher proportions of case-fatality and intracranial injury compared to seat belt group (both P < 0.001). Compared to seat belt group, AORs (95% CIs) of no seat belt group were 10.43 (7.75-14.04) for case-fatality and 2.68 (2.25-3.19) for intracranial injury respectively. In the interaction model, AORs (95% CIs) of no seat belt use for case-fatality were 11.71 (8.45-16.22) in drivers and 5.52 (2.83-14.76) in non-driving passengers, respectively. Wearing seat belt has significantly preventive effects on case-fatality and intracranial injury. Public health efforts to increase seat belt use are needed to reduce health burden from RTIs.

Nitric oxide synthases (NOSs) that catalyzed the conversion of L-arginine to nitric oxide and L-citrulline play a role in ischemic-reperfusion injury. The purpose of this study was to observe the expression patterns of nNOS, iNOS and eNOS in the rat tibialis anterior and soleus muscles after multiple cyclic episodes of ischemic preconditioning (IP). Nine weeks old male SD rats were divided into control and IP groups. The IP group was further divided into 3 groups based on cycle of IP. For IP, left commom iliac artery was occluded 3, 6 and 10 times for 5 minutes ischemia followed by 5 minutes reperfusion using rodent vascular clamps. The animals were sacrificed at 0, 3, 6, 24 and 72 hours of reperfusion and the left tibialis anterior and soleus muscles were removed. The expression of nNOS, iNOS and eNOS were examined with immunohistochemical methods and Western blot analysis. IP increased the expression of nNOS, compared with the control. In the tibialis anterior muscle, the levels of nNOS in the 3IP and 6IP were higher than that in 10IP. IP increased the expression of iNOS, compared with the control, and the levels of iNOS in tibialis anterior muscle were higher than that in soleus muscle. The level of iNOS in the 10IP was higher than those in the 3IP and 6IP. IP increased the expression of eNOS, compared with the control, and the level of eNOS in soleus muscle were higher than that in tibialis anterior muscle. At 0 and 3 hours after reperfusion, the level of eNOS in 6IP and 10IP were higer than that in 3IP. In summary, these results suggest that the ischemic preconditioning increases the expression of nNOS, iNOS and eNOS, and 10 times of ischemic preconditioning may induce ischemic injury through upregulation of iNOS. And tibialis anterior muscle is more susceptabile to ischemic injury than soleus muscle.

A 77-year old woman was referred to hospital with dyspnea and chest dull pain for 5 months. The chest radiograph showed a mass located in the mediastinum. Trachea was deviated to right side. Chest computed tomography showed an enhancing large mass at the middle mediastinum. Endobronchial ultrasonography showed hyperechoic mediastinal mass. We performed endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA). Histologic finding was thyroid tissue with a benign looking papilla. Ectopic thyroid is an uncommon embryological aberration characterized by the presence of thyroid tissue in a site other than in its usual pretracheal region. It occurs along the path of descent of the developing thyroid primodium from the foramen cecum. It is extremely rare for mediastinal ectopic thyroid tissue diagnosised by EBUS-TBNA, so we report here on a case of mediastinal ectopic thyroid and we review the relevant medical literature.

OBJECTIVES: To assess the distribution of social support, and explore its effects on self-rated health status in a low income neighborhood of Seoul, Korea. METHODS: In September 2001 we conducted a survey in a low income neighborhood of Seoul, Korea, in which 862 residents, aged 18 years or over, participated. We measured the general sociodemographic characteristics, self-rated health status and social support with the instrument developed from Korean translation of the Medical Outcomes Study Social Support Survey (MOS-SSS) scale of the US. Logistic regression was used to identify the determinants of social support, and explore its effects on self-rated health status. RESULTS: Lower social class, women or divorced people had much less social support compared to higher social class, men or those never married, respectively. Those families on much lower income also received less social support. Social support has a positive impact on the self-rated health status, which remains statistically significant even when other relevant variables are adjusted. CONCLUSIONS: This study suggests that social support has an important role in health, and the socially disadvantaged have lower social support. Therefore, to improve the health status of the poor, it is necessary to encourage community participation, and develop strategies that could strengthen their provision of social support.

We analyzed alcoholic extracts of herbs possessing anti-neosporal activity against Neospora (N.) caninum. To identify the chemical components of Sophora (S.) flavescens and Torilis (T.) japonica associated with anti-neosporal activity, specific fractions were isolated by high-performance liquid chromatography (HPLC). In vitro activity of the fractions against N. caninum was then assessed. Gas chromatography/mass spectrometry (GC/MS) was used to identify and quantify specific anti-neosporal molecules in the herbal extracts. Almost all HPLC fractions of S. flavescens and T. japonica had higher levels of anti-neosporal activity compared to the not treated control. Active constituents of the extracts were sophoridane, furosardonin A, and tetraisopropylidene-cyclobutane in S. flavescens; 5,17-beta-dihydroxy-de-A-estra-5,7,9,14-tetraene, furanodiene, and 9,12-octadecadienoic acid (Z,Z)-(CAS,1) in T. japonica.

BACKGROUND: Vitiligo is a common disorder caused by a loss of epidermal pigment cells. The pigment cells in the skin and uveal tract are similar in their physiology and morphology and share a common embryologic origin. OBJECT: The purpose of our study was to determine the nature of the relationship between vitiligo and ocular disease. METHODS: Fifty-two patients with vitiligo were examined for ocular abnormalities. RESULTS: There were 17ocular abnormalities our study; 5 fundal focal hypopigmented spots (9.6%), 6 iris pigment clumps(11.5%), and 6 lens opacity(11.5%). CONCLUSION: We believe that vitiligo may affect pigment cells in the eye. Therefore, all patients with vitiligo should have ocular examinations.

Mycobacterium neoaurum is rapidly growing mycobacteria that can cause human infections. It commonly causes bloodstream infections in immunocompromised hosts, and unlike other mycobacteria species, it rarely causes pulmonary infections. We confirmed the first pulmonary infection case in Korea caused by M. neoaurum using full-length 16S rRNA gene sequencing.
