2.Relationship Between Bone Mineral Density and Body Composition in Pre- and Post-menopausal Korean Women.
Korean Journal of Health Promotion 2013;13(2):52-60
BACKGROUND: To investigate the relationship between body composition and bone mineral density (BMD) in preand post-menopausal women in Korea. METHODS: The data of 4,334 pre- and post-menopausal women older than 20 years from the Korea National Health and Nutrition Examination Survey conducted in 2008-2009 were assessed. BMD and body composition were measured by dual-energy X-ray absorptiometry. All analyses except stepwise multiple linear regression analysis were performed using the KNHANES sample weights to account for the complex survey design. RESULTS: After adjusting for confounding variables, lean mass and fat mass were positively correlated with BMD at both L1-4 spine and femur neck in both pre- and post-menopausal women (P<0.001). For the pre-menopausal women, lean mass was the most important determinant of BMD at both sites (R2=0.156 for L1-4 spine BMD, R2=0.168 for femur neck BMD), and the impact of fat mass were minimal. For the post-menopausal women, fat mass had a greater influence on the BMD at L1-4 spine than lean mass (R2=0.016 vs. R2=0.077), but lean mass had a greater impact than fat mass on the BMD at the femur neck (R2=0.077 vs. R2=0.007). After adjusting for confounding variables, post-menopausal osteoporosis increased as both lean mass and fat mass decreased (P(trend)<0.001). CONCLUSIONS: In Korean pre- and post-menopausal women, both lean mass and fat mass had positive correlations with the BMD at both sites and decreased the risk of osteoporosis. Lean mass had a greater influence on premenopausal BMD at both sites and postmenopausal BMD at the femur neck, whereas fat mass had greater influence on post-menopausal BMD at L1-4 spine.

NK/T cell lymphoma is a distinct clinicopathologic entity which is more prevalent in Asia than in America and Europe and is highly associated with Epstein-Barr virus (EBV) infection. Although the clinicopathologic features of the tumor have been clearly defined, genetic changes and roles of virus associated with the development and progression of tumor have not been well studied. In this study, we carried out polymerase chain reaction (PCR) for EBNA-3B, EBNA-3C, and LMP-1 30 bp deletion to investigate EBV subtype and variants in tumor tissue and performed comparative genomic hybridization (CGH) to screen chromosomal imbalances using frozen tissues from 7 patients with nasal-type NK/T cell lymphoma and 1 patient with blastic NK cell lymphoma. Of 6 cases infected with EBV, there were EBV type 1 in six, LMP-1 30 bp deletion variant in four, and LMP-1 40 bp deletion variant in one. Frequent chromosomal imbalances included deletions at 1p31-pter (4), 12q23-q24 (3), and 17p (4), and gains at 2q (5), 10q (3), and 13q34-qter (4). Blastic NK cell lymphoma displayed deletions of 9q, 7q, and 6q, similar to that of nasal-type NK/T-cell lymphoma. With these results, we assumed that candidate genes in these imbalanced chromosomal loci would provide the clue for further molecular studies to identify putative tumor suppressor genes or proto-oncogenes associated with pathogenesis of this neoplasm.

PURPOSE: The purpose of this study is to investigate clinical features and causative organisms in febrile infants younger than three months, to help identification of high risk patients for serious bacterial infection (SBI). METHODS: A total of 313 febrile infants younger than three months, who had visited Seoul National University Children's Hospital from January 2008 to December 2010 were included. Clinical features, laboratory findings, causative organisms, and risk factors of SBI were analyzed by retrospective chart review. Causative bacterial or viral pathogens were identified by gram stain and cultures, rapid antigen tests, or the polymerase chain reaction from clinically reliable sources. RESULTS: Among 313 infants, etiologic organisms were identified in 127 cases (40.6%). Among 39 cases of bacterial infections, Escherichia coli (66.7%) and Streptococcus agalactiae (12.8%) were common. Enterovirus (33.7%), respiratory syncytial virus (19.8%), and rhinovirus (18.8%) were frequently detected in 88 cases of viral infection. Patients with SBI (39 cases) showed significantly higher values of the white blood cell count (14,473+/-6,824/mm3 vs. 11,254+/-5,775/mm3, P=0.002) and the C-reactive protein (6.32+/-8.51 mg/L vs. 1.28+/-2.35 mg/L, P<0.001) than those without SBI (274 cases). The clinical risk factors for SBI were the male (OR 3.7, 95% CI 1.5-8.9), the presence of neurologic symptoms (OR 4.8, 95% CI 1.4-16.8), and the absence of family members with respiratory symptoms (OR 3.6, 95% CI 1.2-11.3). CONCLUSION: This study identified common pathogens and risk factors for SBI in febrile infants younger than three months. These findings may be useful to guide management of febrile young infants.

Because the postmortem changes rapidly distort values of many constituents in the body fluids, the determination of postmortem chemical changes and relation among body fluids is very important in medicolegal community. A laboratory result is not useful if appropriate data for comparison are lacking. The aim of this paper is to determine the reference ranges and the postmortem changes for chemical constituents in postmortem specimen. We examined 17 clinical laboratory parameters in cadaveric blood and vitreous humor obtained from 51 autopsy cases. The mean, standard error, standard deviation and confidence interval of all measured constituents were shown in Table 2 & Figure 1. The postmortem blood level of amylase, phosporus, LDH, ALT, AST and CPK are very higher than those of antemortem blood. The postmortem vitreous level of total bilirubin, triglyceride, GGT, alkaline phosphatase, albumin, total protein and cholesterol are very low and is not reliable. The ratio of vitreous/blood in calcium, BUN, creatine and uric acid are 0.74, 0.68, 0.29 and 0.23 in decreasing orders(Table 3,4). For the medical examiner or pathologist, routine chemical examinations of the vitreous humor can provide evidence of abnormality not apparent in gross or microscopic examination of the tissue. A more extensive study will be required, using a larger number of subjects, to establish the full range of variability.
