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.

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.

Acute aortic dissection is the most common catastrophic illness of the aorta. Left untreated, about 75% of patients with dissections involving the ascending aorta die within 2 weeks of an acute episode, but survival may be significantly improved by the timely institution of diagnostic modalities and appropriate medical and surgical therapy. But, approximately 10-20% of patients with acute aortic dissection present with a clinical picture of acute myocardial infarction. This sometimes can not only delay the diagnosis and adequate treatment of acute aortic dissection but also inappropriately treat with thrombolytic agents and anticoagulants which result in rapid deterioration of clinical condition of patient. We report a case of acute aortic dissection with dynamic ST changes in electrocardiogram which resulted in delay of accurate diagnosis and adequate treatment of acute aortic dissection.

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.

BACKGROUND: Even though surgery and anesthesia give stress to patients, adequate anesthesia could attenuate stress reactions and minimize side effects from these reactions. Abnormal glucose homeostasis is well documented side effect during anesthesia, especially when inhalational anesthetics are used. We planned this study to investigate and compare the effects of two popular anesthetics-between propofol, intravenous anesthetics, and enflurane, inhalational agents on blood glucose level. METHODS: Adult patients free of diabetes mellitus and any other endocrine disease were randomly allocated into two groups. In both groups, anesthesia was induced with 2.5% pentothal sodium 5 mg/kg and succinylcholine 1 mg/kg. After intubation, propofol 6~10 mg/kg with 50 % N2O-O2 mixture 4 liter were used for maintenance in one group (Group P). In other group, enflurane 1.5~2% with 50% N2O-O2 mixture 4 liter were used (Group E). Hartmann's solutions were used for maintenance fluid in both groups. Blood glucose levels were measured at preintubation period, postintubation 5, 10, 15 minutes and just-preincision period. Blood glucose level at admission was regarded as control value and statistical analysis was done by Student's t-test. RESULTS: In group E, there was significant increase of the blood glucose level about 23 minutes after induction but in group P, there was no significant increase of glucose level during entire experimental time. Blood glucose levels were higher from postintubation 5 minutes to just-preincision period with statistical significance in group E than group P. CONCLUSIONS: Propofol maintained stable blood glucose level compared to enflurane during general anesthesia.

Authors observed many cases of vertical deviation in the patients complaining of marked asthenopia. Of 1275 cases who had refraction, there were 183 cases of vertical deviation (13.54%) in our clinic, during the last 2 years from July 1, 1973 to August 31, 1975. In the series of our observation, the females were much more frequent than the males in numbers, especially after 30 years of age group. The right hyperphoria was more frequent than the left. In the most of the vertical deviation, the degrees of deviation were less than one prism diopter and associated with low grade of refractive errors (less than +/- 0.5 diopter). If the marked refractive error was corrected without correction of vertical deviation, the headache appeared to be increased in the cases of marked refractive error associated with vertical deviation. In the majority of the cases who had vertical deviation, the headache (marked asthenopia) was complained of and in the many cases of them the head was tilted slightly to one shoulder. 1) In the many cases, the headache was occipital in character. 2) The headache seemed to be marked in looking the moving picture or on walking the streets (by the looking of moving objects). 3) The headache started easily by looking out of door in the railway journey or driving. 4) The headache occured usually by the exercise or home work and increased in the afternoon while they were comfortable early in the morning.
