`Purpose: To assess macular function by multifocal electroretinography after reattachment of macula-off retinal detachment and to evaluate relationship between duration of macular detachment (DMD) and functional recovery. Methods: Nineteen patients (19 eyes) with macula-off rhegmatogenous retinal detachment underwent pneumatic retinopexy or scleral buckling. Retinal reattachment was obtained successfully in all patients. Duration of follow-up of all patients is at least more than 12 months. Eyes were divided into 2 groups, corresponding to the DMD : Group A (within 7 days, n=9 eyes), Group B (>7 days, n=10 eyes). The amplitudes and implicit times of N1-wave and P1-wave of mfERGs in Area 1 (Ring 1), Area 2 (Ring 1+2) were compared between Group A and B and between Group A and control group. Results: The P1 amplitudes in Area 1 and 2 were significantly different between Group A and B (P<0.05). N1 amplitudes in Area 1 were significantly different between Group A and B (P<0.05), but no significant difference of P1 amplitudes in Area 2 between Group A and B (P>0.05). There were no significant difference of all data between Group A and control in Area 1 and 2 (P>0.05) The implicit times of N1, P1 were not significantly different between Group A and B. Conclusions: The DMD plays a key role in recovery of visual function after reattachment. The mfERG is a useful tool to evaluate the recovery of macular function after reattachment of macula-off retinal detachments.`

N/A Objective : The purpose was to test the hypothesis that the common missense mutation of 5,10-methylenetetrahydrofolate reductase(MTHFR) is more prevalent among preeclamptic women compared with control and also was to determine whether homocysteine and other lipid profile is changed in pregnant women with preeclampsia. Methods : We measured plasma homocysteine, cholesterol, HDL, LDL, triglyceride, apoprotein B, vitamin B12, and folate in 48 pregnant women without preeclampsia and 22 women with preeclampsia. And the MTHFR genotype was determined with a polymerase chain reaction/restriction fragment length polymorphism method. Results were analyzed with aX2 contingency table and T-test. Results : The prevalence of the MTHFR C677T mutation was not significantly different between the population studied. There was no significant difference in the level of plasma homocysteine, cholesterol, HDL, LDL, triglyceride, apoprotein B, and folate between controls and preeclamptic women. Furthermore, there was a significant difference in the level of plasma vitamin B12 between the population studied. Conclusion : These data suggest that the MTHFR C677T mutation is not a risk factor for preeclampsia in this population. Plasma homocysteine, cholesterol, HDL, LDL, triglyceride, apoprotein B, and folate level are not elevated in preeclamptic women. However, the plasma vitamin B12 level is elevated in preeclamptic women. Further studies are necessary to determine why the plasma vitamin B12 level is elevated in preelamptic women although they did not have vitamin drug.

Background: The diagnosis and management of traumatic craniocervical vessel injuries in emergency department continue to be controversial. Direct surgical repair with parent artery preservation may be still difficult. The purpose of this report is to determine the safety and efficacy of endovascular therapy in the management of craniocervical vascular injuries. Methods: Fifteen patients with traumatic carotid and vertebral lesions were treated using therapeutic endovascular methods. Endovascular therapy was accomplished by implanting the balloons, porous or polytetrafluoroethylene (PTFE)-covered stent, and/or embolic materials including coils or glue. Results: All fistulas and pseudoaneurysms were successfully embolized with coils, glue, or stents. The parent arteries of all patients except two patients were preserved. The reasons of the parent artery sacrifice are that thrombus formation due to coil migration into the parent artery and the existing transection of the parent artery, respectively. No additional surgical procedures for vascular lesions were required. There were no delayed neurological or vascular complications and no lesions recurred during follow-up periods (mean 26.9 months). Conclusion: The goal of endovascular therapy is the selective elimination of the vascular pathology with the normal patency of the cerebral arteries. The author`s experience demonstrates that endovascular therapy using stents, balloons, and coils is both feasible and safe in treatment of the traumatic vascular injuries. Long-term follow-up review of these repairs will be necessary to provide a full evaluation of the safety and efficacy of these devices.

Purpose: The purpose of this case report is to describe accompanying ocular findings, especially optic neuropathy, in a patient with MELAS syndrome. Methods: A 10-year-old male patient who had lactic acidosis and neurological symptoms (loss of consciousness, vomiting, epilepsy, decreased vision, and constricted visual field), underwent a brain magnetic resonance imaging (MRI) scan and a molecular genetic analysis. Results: A diagnosis of cerebral infarction due to occlusion in the right posterior cerebral artery was made and confirmed by MRI scan. The diagnosis of MELAS syndrome was confirmed by performing molecular genetic analysis demonstrating the transformation of the mitochondrial tRNAleu(UUR) gene (MTTL1) A to G(3243). According to the ocular examinations, the patient??s left eye showed decreased vision, hemianopsia, relative afferent pupillary defects, mild swelling of optic nerve, and decreased amplitude on visual evoked potential exam. Conclusions: We encountered a case of MELAS syndrome involving optic neuropathy, which can (although rarely) occur with this syndrome. Therefore, in patients with an optic neuropathy of uncertain etiology, clinicians should consider performing comprehensive ocular exams and molecular genetic exams to rule out the possibility of genetic diseases.

목적: VBAC 성공률을 높이고, 무리한 시도분만에 따른 합병증을 줄이기 위하여 VBAC 성공인자에 대한 연구와 더불어, VBAC 성공군과 실패군에서의 산과적 및 신생아 합병증을 살펴보고, VBAC 군과 미분만부 및 다분만부 간의 분만 진행시간 비교를 통하여 VBAC의 난산 기준 설정 및 안전성에 대한 평가 기준을 확립하고자 하였다. 연구 방법: 98예의 VBAC 시도분만 중 자연분만에 성공한 61예를 성공군으로 설정하였고, 자연분만에 실패한 37예를 실패군으로 설정하였다. 분만 진행시간 대조군으로는 단태아, 두위임신이면서 만삭 질식분만을 한 미분만부와 두 번째 질식분만을 한 다분만부 중 각각 100명을 무작위 추출하여 비교군으로 설정하였으며, 의무기록 및 분만 기록지를 검토하여 후향적 연구를 시행하였다. 결과: 분만력, 선행 제왕절개 횟수, 재태 연령, 초음파로 예측한 태아 몸무게, 신생아 몸무게, 입원 당시의 자궁경부 소실과 개대 정도, Bishop score, 자연 진통 유무 및 프로스타글란딘 혹은 옥시토신의 사용 유무가 VBAC 성공 예측에 의미 있는 인자로 나타났다. 그 중 초음파로 예측한 태아 몸무게와 자궁경부 소실정도 및 옥시토신을 사용하여 진통 증강을 시킨 경우가 VBAC의 성공과 실패에 가장 관련된 인자로 나타났다. VBAC 성공군의 분만진행 시간은 분만 1기 활성기 및 분만 2기 모두 미분만부군보다 통계학적으로 유의하게 짧은 반면, 두 번째 다분만부보다는 유의하게 길었다. 결론: VBAC의 성공인자 및 분만 진행의 특성을 바탕으로 VBAC의 기준안을 만들고 이에 따라 VBAC을 실시한다면 불필요한 반복 제왕절개술을 줄이게 되어 임산부 개인 및 사회 경제적으로도 이익을 주는 데 큰 역할을 할 것으로 기대된다. Objective: The purpose of this study was to determine which factors influence the likelihood of successful trial of labor, to evaluate the risks of VBAC and to evaluate the criteria of dystocia and the safety of VBAC. Methods: This retrospective study was peformed based on 61 pregnant women who succeeded VBAC, 37 VBAC failure women, 100 nulliparas and 100 multiparas. Results: In clinical characteristics, the parity, the number of previous cesarean section, gestational age, estimated fetal body weight by ultrasonography, and neonatal body weight had notable differences between the success and the failure group. In obstetric and historical factors, cervical effacement, dilation, and Bishop score at admission, spontaneous labor and method of induction of labor had differences. Among these factors, estimated fetal body weight by ultrasonography, cervical effacement and augmentation of labor using oxytocin were the most prognostic factors affecting the success of VBAC. In VBAC group, the duration of active-phase, second phase and total duration of labor were 313.5, 36.4 and 350.2 minutes, which were significantly shorter than nulliparas, but longer than multiparas. Conclusion: The trial of labor after cesarean section will decrease repeat operation, if it is performed under exact understanding of successful prognostic factors and the unique time length of labor. It will contribute to increase advantages for mother and economic benefits.

목적 본 연구는 초등교사 스키마니아의 가족여가문화 형성과정을 탐색하고 그것이 신체활동 중심 여가활동에 시사하는 바를 찾기 위한 목적으로 수행되었다. 방법 이를 위해 2021~2022시즌 스키활동을 수행한 한 가족을 대상으로 문화기술적 연구를 실시하였다. 심층면담, 참여관찰, 관련자료를 통해 자료를 수집하였으며 영역분석과 분류분석을 통해 자료를 분석하였다. 결과 초등교사 스키마니아의 가족여가문화 형성과정은 동기기, 준비기, 시작기, 발전기, 정착기의 5단계로 나타나고 있었다. 동기기는 부모의 의지, 자녀의 성장, 코로나19의 영향으로 나타났고 준비기는 경제적 효율성을 고려한 시즌권 선택, 안전을 고려한 시즌방 선정, 자녀의 의견을 반영한 장비구입으로 나타났다. 시작기는 스키장에서 주말 지내기, 제한된 환경과 연습시간, 스키보다 매력적인 주변 환경으로 나타났고, 발전기는 턴과 함께 발전한 스키실력, 주변 사람들의 칭찬과 조력, 자발적 스키활동의 실천으로 나타났다. 정착기는 슬로프 도장 깨기를 통한 도전정신 형성, 가족 결속력의 강화, 다음 시즌 설계하기로 나타났다. 결론 본 연구는 초등교사 스키마니아의 가족여가문화 형성과정을 통해 가족의 결속력과 가족 사랑의 의지를 높이고 코로나19와 같은 감염병 시대에 자연체험형 여가활동을 실천할 수 있는 사례를 제시하였다는 점에서 의미를 지닌다. 더 나아가 이러한 여가활동은 교사가 교직생활에서 오는 스트레스를 해소하고 몸과 마음을 재충전할 수 있는 기회를 제공할 수 있을 것이다. Objectives This study is to explore the formation process of family leisure culture of elementary school teacher ski mania and to find out what it suggests to physical activity-oriented leisure activities. Methods To this end, a cultural and technical study was conducted on a family who skied in the 2021-2022 season. Data were collected through in-depth interviews, participatory observation, and related data, and data were analyzed through domain analysis and taxonomic analysis. Results The process of forming a family leisure culture in elementary school teachers' ski mania was shown in five stages: motivation, preparation, beginning, development, and settlement. The motivation stage was the will of the parents, the growth of the children, and the influence of COVID-19. The preparation stage was the selection of season tickets considering economic efficiency, selection of season rooms(houses) considering safety, and purchase of equipment reflecting the opinions of children. The beginning stage was indicated by spending the weekends at a ski resort, limited environment and practice time, and an environment more attractive than skiing. The development stage appeared as skiing skills developed along with turns, praise and assistance from people around them, and practice of voluntary skiing activities. The settlement stage appeared to form a challenging spirit through trying new slopes seal, strengthen family cohesion, and design the next season. Conclusions This study is meaningful in that it raises family cohesion and will to love family through the process of forming a family leisure culture in elementary school teachers ski mania, and presents a case in which nature experience-type leisure activities can be practiced in an era of pandemic such as COVID-19. Furthermore, these leisure activities will provide teachers with an opportunity to relieve stress from teaching life and recharge their bodies and minds.
