This study was conducted to investigate the relationship of body fatness indicators and serum lipids (total cholesterol, high density lipoprotein (HDL) cholesterol, low density lipoprotein(LDL) cholesterol, triglycerides, myocardial infarction(MI) index) to find anthropometric indicators of body fat distribution that are strongly associated with serum lipids. 347 adult male workers of an industry in Kyungpook province were selected and data on the general characteristics were obtained using questionnaire from June 26 to June 29, 1991. Serum lipids were tested with 5 ml fasting blood and height, weight, circumferences of waist, hip and mid-thigh, five subcutaneous fat thickeness(biceps, triceps, supscapular, suprailiac, thigh) were mea sured using Ultrasound type A TATT. Waist circumference, waist/hip circumference ratio and subcutaneous fat thickness of suprailiac area are significantly increased with increasing age, but thigh circumference is significantly decreased (P< 0.05). These results suggest that central obesity is closely related to age and waist circumference may be the best indicator of body fatness or body fat distribution in men. In younger age group(below 40 year old), the result of canonical correlations analysis suggests that circumferences(0.501) was slightly closely related to serum lipids than subcutaneous fat thickness(0.493), however, in older age group (above 40 year old), subcutaneous fat thickness(0.528) were more strongly associated with serum lipids than circumferences(0.419). Weighted canonical analyses suggest that biceps and suprailiac areas in younger age group and sub scapular area in older age group are stronger indicators of serum lipids among .subcutaneous fatness measurements. Of the circumferences, waist is the most strongest indicator of serum lipids in both age groups. Therefore, it is recommended that circumference of waist and subcutaneous fat thickness of subscapular area should be measured to estimate the degree of central obesity for preventing cardiovascular disease in men.

Congenital megacalyces is a congenital renal disease characterized by hypoplasia of the medulla and a non-obstructive dilatation of the calyces. More than 100 cases have been reported in the literature after first described by Puigvert in 1963, but it has been reported only three cases (two cases of adults and one case of child) in the literatures in Korea. The etiology of the congenital megacalyces is unknown. Renal pelvis and ureter are mostly normal in size and there is no urinary obstruction or reflux. Renal medulla of congenital megacalyces is thinner than that of normal kidney but renal cortex retains its normal thickness and function. This is features that help to distinguish megacalyces from obstructive atropy. The calyces are polygonal in shape and the majority of kidney with megacalyces have increased number of calyces. Since congenital megacalyces is a non-progressive lesion, it is important to recognize the clinical entity and avoid unnecessary surgery. We report one case of congenital megacalyces without urinary obstruction or reflux with a brief review of related literatures.

PURPOSE: These days 5 TU purified protein derivative (PPD) is substituted with 2 TU PPD for the tuberculin skin test, a test essential in the diagnosis of tuberculosis in pediatric population. However, there had been no adequate criteria for the positivity of 2 TU PPD skin test. This study was performed to clarify the criteria of positive reactivity of 2 TU PPD skin test. The reactivity of 2 TU PPD was compared to that of 5 TU PPD. METHODS: One hundred and six medical students were tested with Mantoux method. Diameters of induration were measured 72 hours after the intradermal injections of 2 TU and 5 TU PPDs. Past history and family history of tuberculosis, history of BCG administration and the presence of BCG scar were recorded. RESULTS: One hundred and three subjects completed the study. Mean diameter of 2 TU tuberculin test was 10.3 mm and that of 5 TU test was 14.4mm, which was significantly different (P<0.001). The diameters were 0-24mm in the 2 TU test and 0-25mm in the 5 TU test. The diameter of induration in 2 TU test was positively correlated to that in 5 TU test (r2=0.63). Eighty-six subjects (83.5%) in the 2 TU test and 92 subjects (89.3%) in the 5 TU test had diameters of induration of 5mm or more; 59 (57.3%) subjects in the 2 TU test and 83 (80.6%) subjects in the 5 TU test had diameters of induration of 10 mm or more; 27 (26.2%) in the 2 TU test and 64 (62.1%) in the 5 TU test had diameters of induration of 15mm or more. Seventy-six of 103 subjects (73.7%) had greater diameters of induration in 5 TU test than in 2 TU, 22 (21.4%) had the same diameters, and 5 (4.9%) had greater diameters of induration in 2 TU test than in 5 TU test, and the last 5 subjects had indurations of more than 10mm diameter in both 2 TU and 5 TU tests. CONCLUSION: The criterion of positivity in 2 TU PPD skin test, essential for the diagnosis of tuberculosis, is different from that in 5 TU test. In this study, 6 mm or more was adequate for the criterion of positivity and 10mm or more for the criterion of strong positivity. Further studies should be done to establish a criterion for the pediatric population.

BACKGROUND: Psoriasis is a chronic relapsing skin disorder that is characterized by abnormal epidermal proliferation, inflammation and angiogenesis. It causes emotional and social consequences that go far beyond the skin; therefore, many methods to measure and monitor the severity of psoriasis have been reported. OBJECTIVE: This study aims to evaluate the usability of the flow cytometric analysis of the T cell subsets and their chemokine receptors in the peripheral blood of the psoriasis patients as a severity index. METHODS: The T cell subsets and their chemokine receptor expression (CXCR3, CCR4) in the circulating blood of thirty psoriasis patients (PASI score:2.2~44.2) and twenty healthy controls were examined by flow cytometry. The relationship between the PASI score and the T cell subsets/chemokine receptors was also analyzed. RESULTS: The patients showed significantly higher number of Tc1 (CD8+CXCR3+), Tc2 (CD8+CCR4+) and CXCR3/CCR4 expressing cells than did the control group. Especially, the moderate to severe patients (a PASI score greater that 5) showed a higher number of Tc1, Tc2 and CCR4 expressing cells than did the control group. In the severe patients (a PASI score greater than 10), the frequency of circulating Tc2 cells and CCR4 expressing cells was directly correlated with the PASI score. CONCLUSION: Our findings suggest that flow cytometric analysis of the circulating T cell subsets with further classification could serve as an indicator of the disease severity in psoriasis patients.

OBJECTIVES: This study was conducted to investigate the effects of aircraft noise exposure on children's mental health problems such as depression and personality. METHODS: We obtained data from the health examinations of school children in the vicinity of Gunsan airport. This survey was conducted in the rural area, Gunsan during 2009. The study population included 195 children attending 4th to 6th grade from 6 elementary schools near the airport. Based on 60 Weighted Equivalent Continuous Perceived Noise Level (WECPNL) measures of aircraft noise, participants were divided into 2 groups; the exposure group consisted of 106 children from 4 schools, and the reference group included 89 children from the 2 schools in Gunsan. All children completed questions on general characteristics, the Korean Children's Depression Inventory (KCDI) for depression, and the Korea Human Nature Inspection (KHNI) for personality. RESULTS: Children in the exposure group were at higher risk of depression (5.62, 95% CI 1.12~28.25), and personality changes (2.08, 95% CI 1.07~4.05) than those of the reference group. In particular, children's diligence, cooperation, and concentration, subgroups of personality measure, were affected significantly and negatively, by aircraft noise level. CONCLUSIONS: Our results suggest that exposure to aircraft noise at school is associated with mental health problems in children. Requirements should be implemented to manage aircraft noise of its affect on children's health.

Thoracic intramedullary schwannomas are rare spinal cord tumors. Most of these tumors have been reported as a single lesion in the spinal cord. The authors report the first case of intramedullary schwannoma accompanying by extramedullary beads-like daughter masses of the thoracic spine. A 68-year-old male presented with walking disturbance and decreased sensation below T10 dermatome. Imaging workup revealed an intramedullary mass at T6 and T7. T6 and T7 laminectomy and mass removal were performed. Intraoperatively, extramedullary beads-like daughter masses along the nerve roots adjacent to intramedullary mass were identified. Total removal of intramedullary lesion and partial resection of extramedullary masses were done. Histological analysis confirmed the diagnosis of schwannoma. The patient could ambulate independently at postoperative 1 month without any neurological sequelae. The authors experienced a surgical case of intramedullary schwannoma accompanying by extramedullary beads-like same pathologies in the thoracic spine.
