Muscle transplanation surgery is presently widely accepted as a good precedure not only for cosmetic, but also for functional results, a concept to which Marina's observations on the absence of fixed and predetermined functions in the nuclei and associated tracts of the oculomotor system give great support; however, not everyone is in agreement with this concept. This paper report one case in which the total transplantation of the vertical rectus muscles midway between their insertions and the insertion of the lateral rectus muscle were carried out, in addition recession of the medial rectus muscle and resection of the paralyzed lateral rectus muscle. Our case have been followed up during 8 months to rule out late complications, aspecially ocular movement and diplopia. No late complications, however, have been found up to remaining underaction of the right superior and inferior oblique muscles and also medial rectus muscle. The eyes were straight with abduction of the right eye up to 40 prism diopters. Binocular vision was present and there was no diplopia. The cosmetic result was excellent.

The effect of the Nd:YAG laser on the rabbit retina was evaluated with fundus photography, light microscopy and transmission electron microscopy(TEM), and compared with the effect of the Argon laser. Fundus photography was performed at 2 days, 4 days, 7 days, 14 days, 29 days and 49 days after treatment. The enucleated retina was examined by light microscopy and TEM. In YAG treated eye, laser reaction was not found at 0.5mJ level but laser reaction(G2-3) was found at 1.5mJ level. Laser reaction(G3-4) with expulsive bleeding was found at 2.5 and 3.5mJ level. Bleeding was seemed to be originated from the choroidal layer. 2 days after treatment, hemorrhage was sustained but bleeding was not continued. 7 days after treatment, hemorrhage was completely absorbed. In Argon treated eye, photocoagulation burns was well formed without and bleeding. In pathologic examination of YAG treated eye, full thickness disruption of the retina amd Bruch's membrane and replacement of these layers with fibrous scar tissue were revealed at 2.5 and 3.5mJ level. In 1.5mJ energy level of the YAG laser and Argon laser irradiation, the outer half of the retina, RPE and Bruch's membrane appeared to be pridominantely affected than the inner half of the retina. The extent and character of his to pathology in Argon treated lesion was not so different from that of the YAG laser 1.5mJ lesion.

Situs inversus totalis is a rare congenital condition with a mirror image of the thoracic and abdominal viscera. Although several cases of laparoscopic surgery for treating situs inversus have been reported, we believe that laparoscopic low anterior resection for the rectal cancer associated with situs inversus has not yet been reported on. We recently experienced a laparoscopic low anterior resection for rectal cancer and this was performed on a patient with situs inversus. The patient was a 66-year-old woman who presented with constipation for about 1 month. Chest X-rays showed dextrocardia, and the abdomen CT scans revealed situs inversus totalis with upper rectal cancer. She was successfully treated with laparoscopic low anterior resection even though the surgeon was not familiar with situs inversus totalis.

BACKGROUND: PTEN is a novel tumor suppressor gene located at chromosome 10q23.3. Loss of PTEN function has been implicated in the progression of several types of cancer. Angiogenesis is a critical factor in tumor growth and metastasis. We investigated PTEN expression in invasive breast cancers and described its role in the regulation of angiogenesis related to vascular endothelial growth factor (VEGF). METHODS: Forty-five, surgically resected, formalin-fixed and paraffin embedded breast cancer tissue samples were analyzed for PTEN and VEGF expressions by immunohistochemistry and for microvessel density (MVD) by CD34 immunostaining. RESULTS: Loss of PTEN expression was found in 35.6% (16/45) of the breast cancer tissues, all of which showed positive VEGF expression. Among 29 cases with normal PTEN expression, 15 (51.7%) were VEGF positive. MVD was significantly higher in tumors with a loss of PTEN expression than in those with normal PTEN expression. CONCLUSION: A loss of PTEN expression might increase the VEGF-related angiogenesis in breast cancer. There was no correlation between PTEN expression and clinicopathologic parameters. Detection of the loss of PTEN expression may serve as a useful biologic marker for progression in invasive breast cancer.

BACKGROUND: It has been found that parental role is essential for obesity management in childhood. However, there are few studies concerning parental perception on childhood obesity in Korea. Parental perception on childhood obesity according to weight status in elementary school children was examined. METHODS: The subjects were 3,996 elementary school children and their parents in Busan. The surveys which included socioeconomic characteristics, children's eating habits and activities, parental weight and height, parental perception on childhood obesity, were filled out by parents. Children's body mass index (BMI) were calculated using the height and weight measured in school children were classified into the obese group (BMI 95 Percentile) , the high risk group (85 percentile BMI <95 percentile) and the normal weight group (85 percentile) according to BMI gender and age. The analyses were done using x2_ test and ANOVA. RESULTS: Parental BMI in the obese group was higher than the normal weight group in boys a girls (P<0.001) . Participation in regular exercise was higher among the obese group compared to the normal weight group regardless of sex, but daily exercise time was lesser among the obese group only in boys (P <0.001) . Daily TV watching time was not different according to weight status in both sex. The parents with obese children perceived their children's weight as an appearance problem or a health problem about 7-18 times more likely than the parents of children with normal weight. 70% of obese children have tried weight control. The proportion of parental understanding on childhood obesity as a disease was not different among boys, but different among girls (P<0.001) . Eighty five percents of the parents perceived childhood obesity as a disease or a risk factor. But, their perception for the association of hypertension, fatty liver, sleep apnea syndrome with obesity was relative low. CONCLUSION: Most parents with obese children perceived childhood obesity as an appearance problem, a health problem and as a disease or a risk factor.

BACKGROUND: The purpose of this study was to find the factors associated with becoming obese children during the past 2 years in 6th grade children of elementary school and then to evaluate the high risk groups for childhood obesity. METHODS: The 738 children from May to June, 2001 in 6th grade of 5 elementary schools in Busan were the subjects of this study. The children's height and weight in 4th grade and 6th grade were obtained from school health records. We calculated the body mass index in 4th and 6th grades and classified into 3 weight groups (normal, at risk for obesity, and obese) according to the age and sex-specific BMI established by the Korean Academy of Pediatrics. If children's weight group in 4th grade was changed to heavier weight group in 6th grade, we defined it as increased group. Otherwise, we defined it as non-increased group. The association between the increase in weight group and parental and children's characteristics were analyzed by x2-test, x2-test for the trend, t-test, ANOVA and multiple logistic regression. RESULTS: Among the total, 3.3% of children with normal weight and 16.9% of children at the risk for obesity in 4th grade were transformed to increased group in 6th grade, respectively (P<0.001). Children who had excessive appetite (P<0.001), watched TV greater than or equal to 2 hours per day (P=0.004) or had an obese father (P=0.044) were more likely to become increased group. After adjusting for father's obesity, appetite and TV watching time in children, the odds ratio of transforming to increased group after 2 years in children at risk for obesity or in obese child in 4th grade was 2.5 (95% CI: 1.09~5.55) compared to children with normal weight. Children having excessive appetite were 3.2 times (95% CI: 1.42~7.01) more likely to become the increased group after adjusting for father's obesity, TV watching time and weight in 4th grade. Children watching TV greater than or equal to 2 hours/day was 2.8 times (95% CI: 1.27~6.18) more likely to become increased group after adjusting for father's obesity, appetite and weight in 4th grade. CONCLUSION: The risk of becoming obese was higher in children at risk for obesity or obese children in those with excessive appetite or those who have watched TV> or =2 hours/day for the past two years. These findings suggest promotion of educational plan to prevent childhood obesity.

PURPOSE: It has been shown that the inorganic polyphosphate is effective for the regeneration of bones through the preliminary animal test of rabbits. The most effective concentration of the polyphosphate, however, is not known yet. Moreover, the effectiveness of carriers inside human body is not confirmed.. MATERIALS AND METHODS: In this study, we examined the effect of the concentration of the inorganic polyphosphate on the process of the bone regeneration using the 6 weeks old rabbits with the weight of 2.0 kg in average. We performed the experiment using TR-ePTFE membrane(membrane) filled with collagen immersed in 4%, 8% of inorganic polyphosphate, respectively, following removal of the proper sized cortical bones from the rabbit calvaria. The experimental results were compared with the one of the following four groups: The negative control group for membrane only, the positive control group for membrane filled with collagen, the first experimental group for membrane filled with collagen immersed in 4% of inorganic polyphosphate, and the second experimental group for membrane filled with collagen immerse in 8% of inorganic polyphosphate. The fragments of the tissue with membrane obtained from each group of the sacrificed rabbits for 8 or 16 weeks sustained after surgery were then prestained by the Hematoxylin-Eosin stain and coated by resin to form non-decalcified specimens for the histologic examination and analysis. New bone formation was assessed by histomorphometric and statistical analysis. RESULTS: 1. All groups have shown better bone regeneration at 16weeks than 8weeks. 2. Negative control group has shown more bone regeneration relative to the other groups at 8 and 16 weeks. 3. All experimental groups have shown better bone regeneration relative to positive control group. 4. At 16 weeks, the first experimental group has shown more bone regeneration compared to the second experimental group. Exophytic bone formation is not good at the first and the second experimental groups compared with negative control group. But, the use of 4% inorganic polyphosphate was more effective to bone formation than the use of 8% inorganic polyphosphate. CONCLUSION: With above results, it is suggested the use of inorganic polyphosphate with vehicle under TR-ePTFE membrane.

The purpose of this study is to evaluate the regenerated bone histollogically using titanium reinforced ePTFE(TR-ePTFE) membrane and to investigate cell occlusiveness, wound stabilization and tissue integration of TR-ePTFE membrane. Adult male rabbits (mean BW 2kg) and TR9W (W.L.Gore&Associate.INC,USA) were used in this study. Intramarrow penetration defects were surgically created with round carbide bur(HP long #6) on calvaria of rabbits. TR-ePTFE membrane was applied to defect. Then guided bone regeneration was carried out using TRePTFE membrane and resorbable suture. At 2,4,8,12 weeks after the surgery, animals were sacrificed. Nondecalcified specimens were processed for histologic analysis. The result and conclusion of this study were as follows: 1. TR-ePTFE membrane had good ability of biocompatibility and cell occlusiveness. 2. space making for guided bone regenerayion was good at TR-ePTFE membrane. 3. Tissue integration was not good at TR-ePTFE membrane. So, wound stabilization was not good. 4. At 8 weeks, 12 weeks after GBR procedure, bone formation was seen. From the above results, TR -ePTFE membrane fixed tightiy on alveolar bone might be recommended for the early bone formation.

OBJECTIVE: To investigate nationwide statistics on flow-diverting stent usage for cerebral aneurysm treatment and related mortality data.METHODS: We requested data extraction from the National Health Insurance Service claims database using electronic data interchange codes (J3207064, J3207073). Patient and hospital information as well as death statistics were collected from the database.RESULTS: A total of 169 procedures were performed using flow-diverting stents for cerebral aneurysm treatment from November 2014 to December 2016 in Korea. The majority of primary diagnosis was unruptured intracranial aneurysm. During the study period, nine subjects died, including one patient initially diagnosed with subarachnoid hemorrhage. The crude mortality rate was 5.3%. Five patients died within one month after the procedure; therefore, the estimated periprocedural mortality rate was 3.0±1.3%. The mortality rate as of the last day of 2016 was 6.3±2.1%.CONCLUSION: In a 171 person-year follow-up in a Korean series, nine deaths occurred after flow-diverting stent treatment. The crude mortality rate in Korea (5.3%) was higher than that reported in a previous meta-analysis (3.8%).
