Meningioma is usually known to occur stuck to the dura mater, but extradural meningioma occurs rarely. Most of the extradural meningiomas are located in the head and neck and we report a case of the primary intraosseous meningioma in the orbit. A 50-year old woman presented with the left eye hyperemia and exophthalmos. Neuroimaging modalities showed hyperostosis at the left sphenoid and orbital wall. On microscopic view, spindle cells and psammoma bodies between the woven bones were observed. The origin of the intraosseous meningioma is explained with various potent possibilities and differential diagnosis thoroughly explored.

To determine the therapeutic effect of closed-needle irrigation of knee for pain from osteoarthritis(OA), we conducted a randomized, single blind, 8 week prospective trial study. A comparison was done between the closed-needle irrigation of knee and standard conservative treatment in 30 patients with non-end stage OA of the knee. Statistically significant differences (P<0.05) favoring closed-needle irrigation of knee over conservative treatment were noted by the Visual Analog Scale for pain in these patients. Overall assessments on effectiveness of therapy by patients(Patient's global assessment) and physician(Knee rating scale) were also statistically superior among closed-needle irrigation group. We conclude that the closed-needle irrigation of knee for the treatment of pain from osteoarthritis is an effective treatment and is superior than the traditional conservative treatment in therapeutic effect.

Essential osteolysis is very rare, slowly progressive disease. Its etiology and pathophysiology is still unknown. Only one case has been reported in Korea. We experienced one case of essential osteolysis associated with renal insufficiency involving bilateral carpal, metacarpal, tarsal, metatarsal bones, elbow, ankle. We report a case of 24-year-old female who had manifestations of essential osteolysis with renal insufficiency with brief review of literatures.

Although acute renal failure is common in patients with fulminant hepatitis, it has been recognized as a rare complication of non-fulrninant acute hepatitis A. So far about 30 patients have been described in the literature who had acute hepatitis A associated with acute renal failure. Variable renal biopsy findings have been described in previous reports, including mostly acute tubular necrosis, mesangial proliferative glomerulonephritis, and interstitial nephritis. But the exact mechanism by which hepatitis A causes acute renal damage is still obscure. We describe two cases with acute hepatitis A, proven by IgM anti-hepatitis A antibodies compli- cated by acute renal failure. One patient required hemodialysis. Kidney biopsy findings showed interstitial nephritis with no evidence of glomerular involvement. Our review of these cases and the relevant literature suggests that there is strong evidence to implicate hepatitis A virus as a cause of acute renal failure. It remains to be elucidated why the histologic features are variable in the cases of hepatitis A virus induced acute renal failure and which factors predispose a patients to have immunologic involvement versus interstitial and tubular involvement.

PURPOSE: The purpose of this study was to identify the impacts of job stress and job embeddedness on presenteeism among container terminal workers. METHODS: The participants were 299 workers at the S Harbor in P City. Data were collected from April 22 to June 5, 2015. The data were analyzed using t-test, ANOVA, Scheffé's test, Pearson's correlation coefficients, and logistic regression. RESULTS: These workers on presenteeism were affected by the department of work, annual pay, and exercise of more than 30 minutes per day, revealing a statistically significant difference according to these variables. In other words, when job stress was high, job embeddedness was less, the extent of work impairment was higher, and in turn perceived productivity was lower. Work impairment was 3.11 times higher in workers with above-average job stress than those with lower job stress. Perceived productivity was 2.31 times higher in workers with above-average job embeddedness than those with lower job embeddedness. CONCLUSION: To reduce work impairment and increase productivity among container terminal workers, it is necessary to decrease their job stress, to increase their job embeddedness, and especially to do exercise for more than 30 minutes a day.

PURPOSE: The appropriate age and amount that whole cow's milk and commercial baby food can be introduced safely into the infant diet are unknown and remains an area of controversy. Early feeding of excessive amount of whole cow's milk has been associated with iron deficiency anemia and nutritional deficiency. We studied the present status and problems on the feedig of whole cow's milk and commercial baby food in children. METHODS: This survey was done through questionnaire to the 541 out patients who visited Seoul, Chun An and Eum Sung Soon Chun Hyang University Hospitals during the period from Jun. 1994 to Fab. 1995. RESULTS: 1) Feeding patterns according to age of children: Infants were fed prepared milk(63.6%), human milk(16.2%), whole cow's milk(8.1%), commercial baby food(7.1%) and rice(5.0%) in the order of frequency. Children between 1 and 2 years of age were fed rice(37.1%), whole cow's milk (34.3%), prepared milk(17.1%), commercial baby food(7.4%) and human milk(4.0%) in the order of frequency. 2) Whole cow's milk feeding was started at 3 to 6 months of age in 11.5%, at 7 to 12 months of age in 59.6% and after 12months of age in 28.9%. 3) The daily feeding amounts of whole cow's milk was less than 500 ml in 48.2%, 500 to 999 ml in 36.2%, and more than 1000 ml in 15.6%. Suprisingly 49.7% of them were fed more than 500 ml a day. 4) About iron content in whole cow's milk, only 25.9% of mothers gave the correct answer. 5) 62.5% of mothers considered that whole cow's milk was the best food in infant period. 6) Only 19.1% of subjects used commercial baby food properly in method and amount. CONCLUSIONS: Whole cow's milk was introduced during early months of life and fed in excessive amount. There was a lack of maternal knowledge about iron content in whole cow's milk. The improper use of commercial baby food produced the numerous nutritional problems. Thus, we need education about whole cow's milk and commercial baby food to mothers.

Cyclin D1, a cell cycle regulator essential for G1 phase progression, is a candidate proto-oncogene implicated in pathogenesis of several human carcinomas including breast carcinoma. We studied the cyclin D1 expression in 101 cases of primary breast carcinoma tissues. The overexpression of cyclin D1 was immunohistochemically demonstrated in 34 (37.8%) of 90 cases of invasive breast carcinoma. Positive cyclin D1 staining was seen in 32 of 79 invasive ductal carcinomas, and 2 of 3 mucinous carcinomas. All 5 medullary carcinomas, 2 invasive lobular carcinomas, and 1 metaplastic carcinoma were negative. Cyclin D1 overexpression was observed in 9 of 11 ductal carcinoma in situ (DCIS). Normal epithelial components, either ductal or lobular, were not immunoreactive for cyclin D1. No significant correlations were observed between cyclin D1 immunoreactivity and other parameters including tumor size, clinical stage, nuclear or histologic grades, lymphatic or angioinvasion, lymph node metastasis, and immunohistochemical status of progesterone receptor, p53 and c-erbB-2. The overexpression of cyclin D1 was positively correlated with estrogen receptor status (p=0.025). Based on our results, the cyclin D1 protein aberration may play a role in tumorigenesis of breast carcinoma, but does not seem to have prognostic value in invasive breast carcinoma without hormonal treatment.

Maple syrup urine disease(MSUD) is an autosomal recessive disorder involving the metabolism of the branched-chain amino acids(BCAA) such as leucine, isoleucine and valine. The disorder is due to a defect in branched-chain alpha-ketoacid dehydrogenase(BCKAD) and the classic form causes rapid progressive and overwhelming illness beginning in the first weeks of life, present with poor feeding, lethargy, change in muscle tone, acidosis, seizures and coma. The goal of therapy in acutely ill patients with MSUD is an immediate reduction in the plasma levels of the BCAAs and branched-chain ketoacids. In this report, we describe an infant with MSUD who was treated by dietary therapy alone. During the therapy, acrodermatitis enteropathica-like syndrome developed with low plasma isoleucine concentration while she was receiving a formula deficient in BCAAs.

PURPOSE: This study was conducted to identify the factors affecting container terminal worker's recovery experience from job stress. METHODS: The subjects were 299 workers from one S dock in P city. Data were collected from April 5 to June 5, 2015 and analyzed by SPSS/WIN 18.0 program using descriptive statistics, t-test, ANOVA, Sheffe test, Pearson's correlation coefficients, and logistic regression. RESULTS: The mean scores of job stress, ego-resilience, and recovery experience from job stress were 47.18, 46.90, and 49.17 respectively. Recovery experience according to the general characteristics showed significant correlation between daily exercise. There was a significant negative correlation between recovery experience and job stress, and a positive correlation between recovery experience and ego-resilience. Recovery experience was 2.54 times higher for a high ego-resilience group than for a low ego-resilience group, and the group that exercised was 2.25 times higher, than the non-exercising group. The group with a low level of interpersonal conflict was 1.97 times higher, than a group with a high level of interpersonal conflict. CONCLUSION: Based on this study, intervention programs to increase ego-resilience, decrease interpersonal conflict, and encourage over 30-minute-daily exercise for in container terminal workers should be developed to improve recovery experience of job stress.
