The Ankle joint is a modified complex hinge joint which plays an importnat role in weight bearing, walking and standing. Injuries about the ankle joint cause destruction of not only bony architecture but also the ligament and soft tissue components. We performed arthrography in 52 cases of ankle fracture. The Result obtained from this study was as follow; The ligament & interosseous membrane injuries were more severe, when fracture of lateral malleolus was occured higher level than ankle joint.

Hereditary anhidrotic ectodermal Dysplasia is a congenital disease displaying characteristics of anhidrosis, hypotrichosis and dental defect which are caused by developmental anomaly of ectodermal epidermis and its appendages. We experienced two cases of hereditary anhidrotic ectodermal dysplasia in two-year and four-month old twin brothers. These patients suffered from intermittent high fever early in life which brought them to our clinical attention. However the diagnosis of anhidrotic ectodermal dysplasia was not suspected by means physicians who cared the patients previously. The diagnosis was made on the basis of clinical features, and confirmed by starch iodine sweat test and skin biopsy on the palm and axilla. We report the two cases in a twin brothers with brief review of related literatures.

We calculated the age specific Proportionate Morbidity Ratio(PMR)' for different areas as the outcome index by using the national cancer registry data(1988 1991) to assess the patterns of stomach cancer and bladder cancer. Also, we calculated 'Manufacturing workers Concentration Index(MCI)' for different areas as the exposure index by using the census data reported in 1980 to assess the relationship between cancer site specific PMRs and MCIs. As a result, we found the significant correlation(r=0.61, p=0.002) between the bladder cancer in the age of 40s and the industrial exposure indicator. Future analytic studies should be fruitful in identifying more occupational risk factors for bladder cancer. Investigation of cancer incidence including geographic variations and difference by age may identify patterns suggesting occupational exposures.

PURPOSE: To investigate the accuracy and usefulness of the retinal acuity meter (RAM) in predicting visual acuity after cataract surgery. METHODS: We randomly selected 47 eyes from 43 patients who underwent cataract surgery in our clinic. Preoperative BCVA and 3 month postoperative BCVA were measured by the Snellen chart, and we recorded the preoperative visual acuity by RAM. We also grouped the patients according to diabetic retinopathy and preoperative BCVA 20/100. By comparing the expected visual acuity by RAM with actual postoperative BCVA values, we analyzed the accuracy of the RAM's predictability after surgery. The cataract types and macular disease were taken under consideration when analyzing our results. RESULTS: Of the 47 eyes in our study, the postoperative Snellen visual acuity was predictable within three lines (90.9%) in 11 eyes with diabetic retinopathy and without macular disease. In the 36 eyes without diabetic retinopathy, the postoperative Snellen visual acuity was predictable within three lines (91.6%) of the cases. In both groups, the preoperative RAM acuity and postoperative BCVA were significantly correlated (R2=0.692, R2=0.812, p<0.05). In 41 eyes with preoperative BCVA 20/100 or more, the postoperative Snellen visual acuity was highly predictable in 95.1% (R2=0.763, p<0.05). However, in 6 eyes with preoperative BCVA levels less than 20/100, the postoperative Snellen visual acuity was not predictable (66.6 %). In the patients with both nucleosclerosis and posterior subcapsular opacity and in the patients with additional cortical opacity, the postoperative BCVA differed from the preoperative RAM acuity by more than three lines on the Snellen chart. CONCLUSIONS: RAM is useful in predicting postoperative visual acuity in cataract patients, but may be unreliable in the patients with combined cataract forms or with preoperative BCVAs less than 20/100.

PURPOSE: The aim of this study is to investigate the quality of basic life support (BLS) information for primary Korean-speaking individuals on the internet.METHODS: Using the Google © search engine, we searched for the terms ‘CPR’, ‘cardiopulmonary resuscitation (in Korean)’ and ‘cardiac arrest (in Korean)’. The accuracy, reliability and accessibility of web pages was evaluated based on the 2015 American heart association(AHA) guidelines for CPR & emergency cardiovascular care, the health on the net foundation code of conduct and Korean web content accessibility guidelines 2.1, respectively.RESULTS: Of the 178 web pages screened, 50 met criteria for inclusion. The overall quality of BLS information was not enough (median 5/7, IQR 4.75-6). 23(36%) pages were created in accordance with 2010 AHA guidelines. Only 24(48%) web pages educated on how to use the automated electrical defibrillator. The attribution and transparency of the reliability of pages was relatively low, 20(40%) and 16(32%). The web accessibility score was relatively high.CONCLUSION: A small of proportion of internet web pages searched by Google have high quality BLS information for a Korean-speaking population. Web pages based on past guideline were still being searched. The notation of the source of CPR information and the transparency of the author should be improved. The verification and evaluation of the quality of BLS information exposed to the Internet are continuously needed.

BACKGROUND: An increase in oxidative stress has been suggested to play major roles in the complications of diabetes. The bulk of the experimental data favors enhanced free radicals in diabetes and antioxidant defense mechanisms may be reduced in diabetes. Melatonin, the major secretory product of the pineal gland has been shown to be a potent and specific hydroxyl radical scavenger. The purpose of our study was to determine the antioxidative effeet of melatonin in streptozotocin-induced diabetic rats. METHODS: Sprague-Dawley rats weighing 200-240 g were divided into 3 groups: normal controls(n-7), diabetic contmls(n-9), melatonin-treated diabetic animals(n-9). Diabetes was induced by intraperitoneal injection of streptozotoein(55 mg/kg body weight) and melatonin(6 mg/kg body weight) was orally administered for 20 days. At day 20 after streptozotocin administration, blood was collected for the assay of glucose, albumin and cholesterol. Erythrocyte membrane lipid peroxidation was determined by malonyldialdehyde(MDA) reactivity. RESULTS: 1) The MDA resctivity of erytbrocyte membrane in melatonin-treated diabetic animals (meanstandard deviation: 5.52+-1.52nmol/ml packed cells) were lower(p<0.05) than that in diabetic controls(7.68+-1.16nmol/mL packed cells). But, there was no significant difference between melatonin-treated diabetic animals and normal contls(4.93+-1.19 nmol/mL packed cells). 2) There were no significant differences of blood glucose and body weight between diabetic controls and melatonin-treated diabetic animals. CONCLUSION: These results show the antioxidative effect of melatonin in streptozotocin-induced diabetic rats. Further clinical and long-term experimental studies are needed to assess the effect of melatonin on development and progression of diabetic complications.

BACKGROUND: The aim of this study was to identify causative factors for cerebral white matter changes on MRI and relationship between cerebral white matter changes and cognitive function. METHODS: The patients who were admitted to the Department of Neurology ward or visited to outpatient clinic at the Chungnam National University Hospital from September 1999 to July 2000 were selected. All patients underwent brain MRI with 1.5 T for determination of degree and distribution of cerebral white matter changes. The patients were evaluated their cognitive function with the Mini Mental State Examination (MMSE) and the Modified Mini-Mental State Examination (3MS), which has more extensive and detailed tool for fluency and memory domains of cognition compared with the MMSE. Statistical analyses were performed to identify whether there was difference in causative factors and cognitive status between patients with white matter change and patients without white matter changes. RESULTS: White matter changes were significantly more common in patients with hypertension and women. On correlation analyses, hypertension and aging were significantly related with cerebral white matter changes. General cognitive status in patients with white matter changes were worse than those of patients without white matter changes and of control group. Frontal lobe functions like fluency, attention, and visuo-constructive function were especially affected by white matter changes on the 3MS. CONCLUSIONS: Hypertension, female sex and aging may contribute to the development of cerebral white matter changes. Cerebral white matter changes may be responsible for the general cognitive decline.

OBJECTIVES: Although most of the functional and structural neuroimaging studies have reported the association of the that cognitive deficits in patients with schizophrenia with the pathophysiology of the prefrontal cortex, their findings vary considerably. Based on the precise parcellation methods, this study was designed to investigate substructural abnormalities of the prefrontal cortex in patients with schizophrenia. METHODS: The subjects consisted of twelve patients with schizophrenia and 12 age- and sexmatched normal volunteers. Magnetic resonance images were obtained in all subjects, and parceled into 8 frontal substructures using the topographic landmarks. The frontal substructural volumes were compared between the two groups, and their correlations with the schizophrenic symptom severity were analysed in the patient group. RESULTS: In the comparison of substructural volumes, most frontal substructures of the patient group tended to be smaller than those of the normal comparison group; particularly the right supplementary motor area was significantly smaller(p<0.003). Negative symptoms tended to be inversely correlated with the frontal substructural volumes, particularly with the right superior frontal gyral volume(gamma= -0.70, p=0.01). CONCLUSION: These findings suggest the possibility of structural defects related to 'hypofrontality' in schizophrenia. These frontal structural defects may be the basis of neurocognitive deficits and neural circuital dysfunction in schizophrenia.

A case report described a 72-year-old man with a history of a deceased-donor liver transplantation (due to hepatitis B-associated end-stage liver cirrhosis) performed in 1994. The patient was diagnosed with renal cell carcinoma and pulmonary metastasis in 1997 and was successfully treated with radiofrequency ablation and thoracoscopic superior segmentectomy. There was no evidence of newly diagnosed metastatic lesions or recurrence until the 19th post-operative month. Gastric cancer was identified by endoscopy during a routine follow-up examination; the pre-pyloric antral lesion measured 1.5 cm in size and was histologically well-differentiated and confined to the submucosal layers on endoscopic ultrasound. Laparoscopic gastrectomy and lymph node dissection (D1 + beta) was successfully performed in March 2009, and the patient was discharged on the 5th post-operative day without complications. This suggests that laparoscopic surgery is one of the feasible methods for resection of gastric cancer in liver transplant patients.
