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.

The authors have recently treated a case of intraepithelial epithelioma(Bowen's disease) of the cornea and conjunctiva. This 66 year old male had a gray whitish elevated smooth mass on the lateral area of the corneal limbus and bulbar conjunctiva. Simple surgical excision was indicated since the lesion is benign but it recurred in 10 months. The recurrent lesion was excised again surgically. The histopathological features of previous specimen showed simple proliferation of one of the normal conjunctival and corneal epithelial cells in the epithelial layer, rather then an alteration in the chracter of the cells as the case in other malignant neoplasm. The second excised specimen showed marked proliferated epitheloid cells, keratosis, and chronic inflammatory cell infiltration but the lesion was limited to the epithelial layer without any evidence of invasion into the stroma.

BACKGROUND: This study researched the relationship between shift work and one of its relevant health problems, functional gastrointestinal disorders. The study targeted nurses working at a university hospital, and compared the differences in gastrointestinal disorders of shift workers and non-shift workers and identified causes that significantly influence these symptoms. METHODS: In August 2013, a self-report survey was conducted on nurses working at a university hospital. Among those sent out, 1,201 responded and 851 were used for the final analysis. RESULTS: It was shown that the frequency of gastrointestinal disorders in shift workers was 1.881 times higher than that of non-shift workers. Factors that influenced gastrointestinal disorders included age, marital status, work duration, type of employment, job satisfaction, and perceived health status. Gastrointestinal disorders were seen more often with older age, being married, longer duration of employment, non-regular worker, low job satisfaction, bad perceived health status, and shift works. CONCLUSIONS: To prevent gastrointestinal disorders in nurses who work shifts, a health checkup system should be in place for clinical nurses who are of older age and have longer employment records. To decrease the causes of gastrointestinal disorders, campaigns suggesting regular diet and quitting alcohol use should be held consistently. Also, a category related to gastrointestinal disorders should be added to the employee health checkup for nurses with long work experience.

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.
