The purpose of this study was to investigate the functional recovery of end-to-side neurorrhaphy in rats. There have been several studies about the results of end-to-side neurorrhaphy from a histologic or eletrophysiologic view point. However, histologic or electrophysiologic parameters may not correlate with the actual nerve function. In this study we assessed the results of end-to-side neurorrhaphy functionally using walking track analysis. Forty-eight male Sprague-Dawley rats were randomly divided into 4 group, with 12 rats in each group. Group 1 was the sham-operation group. Group 2 was the peroneal nerve transection group. In group 3, the peroneal nerve was severed and end-to-end neurorrhaphy was carried out. In group 4, the peroneal nerve was severed and coapted end-to-side to the lateral face of the tibial nerve after removal of the epineurium arid perineurium. Walking track analysis was done every 2 weeks up to 16 weeks. Group 3 recovered 80.4% in peroneal function at postoperative 16 weeks, whereas group 4 recovered only 46.0%. In group 2, it was impossible to measure the peroneal function by walking track analysis because of plantar flexion contracture after 6 weeks. We concluded that the end-to-side neurorrhaphy group showed better results compared with the nerve transection group. However, the end-to-end neurorrhaphy group showed still better results in the walking track analysis of rats.

Fibrous dysplasia is a common benign disorder of bone in which normal bone marrow is replaced with fibro-osseous tissue. As PET/CT is increasingly used for the staging of different malignant disease, incidentally found fibrous dysplasia with increased FDG uptake may mimic metastasis. We report on a 46-year-old woman with fibrous dysplasia who underwent PET/CT because of suspected recurrence of breast cancer and was misdiagnosed as a bony metastasis with a focal FDG uptake on left proximal femur. This lesion was interpreted as fibrous dysplasia based on MRI in addition to the plain radiographs. We conclude that MRI in addition to radiography may help to differentiate fibrous dysplasia mimicking metastasis on PET/CT in the patients with malignancy.

PURPOSE: To assess the association between decreased visual acuity (VA) and diagnosis of depressive disorder by a physician or experience of depressive mood using self-report questionnaires. METHODS: We conducted a cross-sectional analysis using nationally representative data from the Korean National Health and Nutrition Examination Survey (KNHANES, 2008-2012). A total of 28,919 adults who had sociodemographic and health behavioral risk factors available were included. An association between decreased VA and depression was identified using multivariate logistic regression analysis after adjusting for possible confounders. Depression was defined as a depressive disorder with a diagnosis by a physician or depressive mood lasting more than 2 weeks using self-report questionnaires. RESULTS: The prevalence of depressive disorder and depressive mood in Koreans was 1,160 (4.0%) and 4,063 (14.1%), respectively. In univariable logistic regression, there was significant association between VA and depressive disorder or depressive mood. However, in multivariable logistic regression analysis, this study found no statistically significant association between VA status and the prevalence of depressive disorder or depressive mood in Koreans. CONCLUSIONS: No association between decreased VA and a depressive disorder/depressive mood in Korean adults after adjusting for possible confounders was found. Therefore, further longitudinal cohort studies examining the causal relationship between decreased VA and depression in Korean adults are necessary.

Among 4465 patients visited in the department of ophthalmology of the our hospital from January 1, 1975 to September 30, 1976, 146 patients (under the age of 25 ; 88 patients, over the age of 26 ; 58 patients) was statistically observed for errors of their glasses. 1) The rate of glasses over or under corrected 0.75D or more was 37%, and of this rate, 12% were over corrected. In age group, it was about twice the age of 25 than over the age of 26. 2) The rate of glasses which diopters of cylindrical lens were wrongly corrected 0.50D or more was 65% (of 156 glasses), and of this rate, 40% were glasses which astigmatism was absent but in refraction astigmatism was present more than 0.50D. In age group, it wasabout 2.5 times the rate of it in under the age of 25 than over the age of 26. The rate of glasses which axis of astigmatism was wrongly corrected 100 on more was 65% (of 52 glasses). 3) The rate of glasses which distance between optical centers was short or long more than 3mm was 53%, and of this rate, the rate of long ditstance between optical centers was 3 times than that of short distance. It was also about twice the rate of in under the age of 25 than over the age of 26. 4) The rate of glasses which corrected 1/2 delta or more was 20%, and of this rate glasses which vertical deviation was present but in examination vertical deviation was not present. 5) Among 146 patient, patients which has worn glasses not to belong to above the categories were only 15 patients and rate of it was only 10%.

The symptoms and signs of acute pulmonary arteries thrombosis are nonspecific. So clinical suspicion is the most important in the diagnosis. Treatment of pulmonary thromboembolism include anticoagulant, thrombolytic agent, or surgical intervention. We experienced a case of recurrent pulmonary thromboembolism without coagulation defect and any risk factor except old age and obese. Initially we treated with heparin, but clinical symptoms were aggravated. After we changed to urokinase (total 330 million IU/2 days), the pulmonary arteries obstruction were resolved and clinical symptoms were improved without any complications. So we report this clinical experience with review of articles.

Subcutaneous fat necrosis of the newborn is an uncommon disorder characterized by firm b-cutaneous plaques and nodules usually appearing shortly after birth. It runs a relatively be, n course and may completely resolve in a few months without any recurrence. We report a case of subcutaneous fat necrosis in a 15 day-old male suffering from severe p inatal asphyxia and hypoxic cardiomyopathy, who presented with indurated subcutane s nodules and plaques on the both shoulders and the back. Histologically the subcutaneous fat showed focal necrosis with needle-shaped clefts, lymphohistiocytic infiltration and foreign body reactions consistent with subcutaneous fat necrosis of the newborn. In our patient, compromised cardiac output due to cardiomyopathy might have aggravated hypoxic condition and it could be speculated that cardiomyopathy-induced systemic hypoxia gave rise to hypothermia of the skin as a result of peripheral vasoconstriction. This report presents a causal relationship of cardiomyopathy and subcutaneous fat necrosis of the newborn.
