In early April 2014, a month-old Alexandrine Paraqeet (Psittacula eupatria) that was raised in a domestic aviary located in Gyungju-si, Korea was suddenly died and submitted to Animal Disease Intervention Center, Kyungpook National University in order to diagnose the causative agent. In post-mortem examination, the bird had abnormally developed feathers on the neck and abdomen region and subcutaneous hemorrhages on the neck and cheek adjacent to the beak. At necropsy, the bird had hemorrhage on the muscle of the femoral region, ascites, multi-focal hemorrhages on the epicardium, and diffuse hemorrhages on the sub-serosa of proventriculus and gizzard, suggesting typical avian polyomavirus (APV) infection. The partial large tumor (T) antigen gene of APV was detected by PCR from tissues of the heart, lung, liver, kidney, proventriculus and feathers of the APV-suspected birds. However, other pathogenic virus-specific nucleic acid common with psittacine birds such as avian bornavirus, psittacine beak and feather disease virus and psittacid herpesvirus were not detected from the mixed tissue samples of the bird, indicating this case is due to single infection of APV. Nucleotide sequence analysis of the partially amplified large T antigen DNA was confirmed to have 99~100% homology with that of the previously reported APV strains. This case report describes the first detection of APV in Alexandrine Paraqeet in Korea.

Purpose: The purpose of this study was to determine whether the rates of (1) in-hospital lengths of stay (LOS), (2) readmissions, (3) medical complications, and (4) costs of care are higher for patients with depressive disorder (DD) undergoing primary total hip arthroplasty (THA) for treatment of femoral neck fractures (FNFs). Materials and Methods: A retrospective query of a national administrative claims database for patients undergoing primary THA from 2006 to 2014 was conducted. Patients with DD undergoing THA for treatment of FNF were 1:5 ratio propensity score matched to a cohort (DD=6,758, controls=33,708). Primary endpoints included LOS, 90-day medical complications, 90-day readmissions, and healthcare reimbursements. A P-value less than 0.05 was considered statistically significant. Results: Longer LOS were observed for patients with DD compared to those without DD (5.6 days vs. 5.4 days, P<0.001). Similar readmission rates (29.9% vs. 25.0%, odds ratio [OR] 1.03, P=0.281) were observed between groups. The odds of 90-day medical complications were higher for patients with DD compared to control subjects (60.6% vs. 21.4%, OR 1.57, P<0.0001). Within the 90-day episode of care interval, patients with a history of DD incurred significantly higher healthcare expenditures ($21,382 vs. $19,781, P<0.001). Conclusion: Our findings showed longer LOS, higher odds of 90-day medical complications, and higher healthcare expenditures within the 90-day episode of care following a primary THA for treatment of FNF for patients with DD compared to the matched cohort. Thus, accordingly, patients with DD should receive counseling prior to undergoing surgery.

Osteoporosis and other related conditions pose a growing public health problem, especially in postmenopausal women. The main purpose of the study was to investigate the correlations among BMD, maternal factors, and life styles, and intake of nutrients in postmenopausal women. One hundred participants in Kyungge-do were divided into three groups according to their BMD measurements measured by DXA. Dietary analysis, anthropometric measurements, and questionares were administered to these women. The percentage of the osteoporosis, osteopenia(Osteopinia), and normal groups were 32%, 48%, and 20% respectively. The average age was significantly the highest in the osteoporosis group. The average age at menopause was 47.2. Osteoporosis group's age at menopause was significantly the lowest. The sleeping hours of the osteoporosis and osteopenia group were significantly longer than the normal group. The intake of vitamin B$_2$was positively correlated with the BMD of femoral neck. The BMD of these two sites was positively correlated with weight, BMI, waist, and hip size and negatively correlated with the length of the menstrual cycle, duration after menopause, the age at the last delivery, and sleeping hours. Spinal BMD positively correlated with hours of outdoor activity. Therefore, maternal factors, lifestyles, and intake of nutrients contribute to BMD.

Bone mineral density (BMD) is one of the quantitative traits that are genetically inherited and affected by various factors. Over the past years, genome-wide association studies (GWASs) have searched for many genetic loci that influence BMD. A recent meta-analysis of 17 GWASs for BMD of the femoral neck and lumbar spine is the largest GWAS for BMD to date and offers 64 single-nucleotide polymorphisms (SNPs) in 56 associated loci. We investigated these BMD loci in a Korean population called Korea Association REsource (KARE) to identify their validity in an independent study. The KARE population contains genotypes from 8,842 individuals, and their BMD levels were measured at the distal radius (BMD-RT) and midshaft tibia (BMD-TT). Thirteen genomic loci among 56 loci were significantly associated with BMD variations, and 3 loci were involved in known biological pathways related to BMD. In order to find putative functional variants, nearby SNPs in relation to linkage equilibrium were annotated, and their possible functional effects were predicted. These findings reveal that tens of variants, not a single factor, may contribute to the genetic architecture of BMD; have an important role regardless of ethnic group; and may highlight the importance of a replication study in GWASs to validate genuine loci for BMD variation.

Osteoporosis is a disease that increases the fracture rates and a major cause of increased mortality and morbidity in the elderly people. This study is to determine which components of body composition and metabolic syndrome risk factors are important to bone health, we analysed the relationship among bone mineral density (BMD), body composition and metabolic syndrome risk factors in females. Totally 630 females participated in a medical check-up program (mean age 47 years) were selected for this study. Body composition analysis was performed by segmental bioelectrical impedance method, muscle mass, and percent body fat were measured. We also measured metabolic syndrome risk factors including abdominal obesity, HDL-cholesterol, triglyceride, blood pressure and fasting glucose level. Metabolic syndrome was defined by NCEP-ATP III criteria. The lumbar spine and femoral neck BMD were measured using the dual energy X-ray absorptiometry. Osteopenia and osteoporosis were observed in 180 and 51 persons, respectively. Muscle mass and HDL-cholesterol decreased in osteopenia and osteoporosis groups compared to the control group, and the grade was shown progressively by the symptoms. Significant positive correlation between BMD and muscle mass was observed. Multi variable regression analyses showed that % body fat and muscle mass were independent predictors of BMD after adjustment of age, height and weight. In conclusion, the BMD showed negative correlation with the metabolic and body composition was associated with BMD.

Low grade central osteosarcoma is an rare variant of conventional osteosarcoma and generally occurs in older age than conventional. We experienced a case of low grade osteosarcoma occurred in a 12 years old female. Moreover, it occurred multifocally in left tibia, left femoral neck and midshaft, and left acetabulum. We could not sure whether it was from synchronous or metachronous metastasis. Usually the low grade osteosarcoma progresses very slowly. But, despite this case was low grade osteosarcoma with very indolent progression, furthermore, it showed synchronous or metachronous metastasis. So we report this unusual case with review of literature.

We studied the effects of soy isoflavones supplementation with exercise on bone mineral density and the urinary excretion of deoxypyridinoline as an index of bone resorption rates in postmenopausal women. A total of 67 postmen-opausal women were assigned to Isoflavone (90 mg/day) or placebo groups. These group were further divided into groups that undergone a regular exercise or a rather sedentary state performing daily activity only. Four groups were Placebo-control group (n = 16), Placebo-exercise group (n = 16), Isoflavone-sedentary group (n = 19) and Isofla-vone-exercise group (n = 16). After the intervention, we compared anthropometric mesurement, dietary recall, bone mineral density (femoral neck, lumbar spine), urinary deoxypyridinoline between the groups and between the pre and post studies. There were no significant differences between the four groups in terms of average age, height, weight, period after menopause at the baseline. The average age of the subjects were 55.2 yrs, average height, weight, period after menopause were 154.7 cm, 59.3 kg, 5.58 yrs, respectively. After eight week intervention period, there were no significant differences between the four groups in bone mineral density, but urinary deoxypyridinoline excretion was significantly decreased both in Isoflavone-sedentary and Isoflavone-Exercise groups. These results suggest that Isofla-vone supplementation alone or with exercise may be preventive measures through the decrease of bone reabsorption rate in post-menopausal subjects. Whereas exercise alone did not appear to be an effective measure in bone loss with these subjects.

Von Recklinghausen's disease is a systemic hereditary disorder with varied manifestations in bone, soft tissue, nervous system, and skin, the most common of which is the developement of multiple, small, cutaneous tumors with a characteristic histologic picture. Tumors develop after birth and before puberty in most cases, and they increase in number until old age. Malignant neoplasms that complicate multiple neurofibromatosis include gliomas of the optic nerve, astrocytomaas of the cerebral and cerebellar hemispheres, and sarcomas of peripheral nerves (femoral, tibial and intercostal nerves) and somatic soft tissues. Little attention has been paid to the presence of cystic lung disease in association with neurofibromatosis. Currently, most think of thoracic involvement in neurofibromatosis in terms of posterior mediastinal neuroma, pheochrocytoma, meningocele or, less commonly parenchymal pulmonary neurofibromas. Author have experienced 2 cases of Von Recklinghausen's disease. One case developed a hyge malignant Schwannoma in the parietal pleura of left 4th intercostal space and multiple benign neurofibromas (two in intercostal spacees and one in the neck) , and the other has several episodes of pneumothorax resulting from diffuse cystic lung disease which required closed thoracotomy drainage.

Vitamin K takes part in both blood coagulation and bone metabolism via the carboxylation of glutamate residues. This study was performed to examine the relationship between dietary phylloquinone intake and bone mineral denisty(BMD) among postmenopausal Korean women (n=70, age=56). The bone mineral density of the lumbar spine and femoral neck were measured by dual X-ray absorptiometry(DEXA). Daily intakes of phylloquinone and calcium were assessed using a food frequency questionnarie. As a results, body weigh, height and body mass index were not correlated with BMD. However, the number of years since monopause and daily intakes of calcium were significantly correlated with BMD. Although daily intakes of phylloquinone were not correlated with BMD, women with relatively high BMD consumed more phylloquinone than those with lower BMD. The average daily phylloquinone and calcium intakes of the 70 postmenopausal women were 725.8ug/day, ten times more than the American RDA and 406.7mg/day, 1/2 of the American RDA for those nutrients, respectively. The major food sources for phylloquinone were seaweed, spinach and kale, whereas the food sources of calcium were milk, sardines, and yogrut. Further studies are needed to clarify the effects of dietary phyloquinone on its serum levels and BMD.

It was hypothesized that variations within the range of usual calcium(Ca) and sodium(Na) intakes of Korean influence bone mineral density(BMD) in healthy premenopausal women The relationship of nutrient intake urinary excretion physical activity and circulating IGF-1 level with spine({{{{ { L}_{2 } }}}}-{{{{ { L}_{4 } }}}}) and femur BMD was determined in 47 normal premenpausal women. There was a positive relationship between BMD of the lumbar spine and body weight. The BMD of femoral neck was positively correlated with Ca and protein intakes from animal source and circulating IGF-1 level. There was a negative relationship between femur BMD and both Na intake and urinary excretion. The complex interrelations between femur BMD regression analysis, From this analysis. Ca intake from animal origin was the only significnat Premenopausal women of femur BMD. In the basis of femur BMD three groups were divided Premenopausal women of femur BMD$\leq$0.84g/cm2 showed depressed Ca intake of animal origin in later and early life and enhanced urinary Na excretion compared to women of femur study suggests that dietary Ca is a major constituent affecting femur BMD because of a decrease in net Ca absorption and an increase in urinary Ca loss.
