Purpose: To design novel balance tests to assess FAI and evaluate whether these tests are affected by BMI or gender, with the goal of developing reliable FAI assessment tests that are not influenced by these factors. Materials and Methods: Participants included 20 young, healthy volunteers, 12 males and 8 females, with a mean age of $24{\pm}4$ years and a mean BMI of $23{\pm}2.28$. None of the subjects had known ankle instability. The following tests were assessed in each participant: single leg balance (SLB), percentage of leg press (PLP), single leg cycling (SLC), one leg squat (OLS), multiple direction reach-front/back/side (MDR-F/B/S), single leg hop (SLH), two leg jump (TLJ) and side step (SS). Data were analyzed using the SPSS 12.0 software program with ANOVA and t-test used. Results: When grouped by BMI, we found that despite differences in BMI, the performances of all subjects were equivalent except for the one-leg-squat test, for which the mean ratios for underweight ($1.69{\pm}0$), normal weight ($1.05{\pm}0.19$), and overweight ($0.93{\pm}0.30$) individuals were significantly different (p=0.02); ratios for SLB (p=0.273), SLC (p=0.903), PLP (p=0.664), MDR-F/B/S (p=0.498, 0.908, and 0.503, respectively), SLH (p=0.332) were not significantly different. When calculated according to gender, we found that the OLS (p=0.013) and MDRS (p=0.034) were significantly different, while parameters for all the remaining tests were not affected. Conclusion: We found that the SLB, PLP, SLC, MDR-F/B, and SLH ratios were unaffected by BMI or sex and, therefore, are reliable parameters for assessing ankle instability.

Background: Osteoporosis is a common disease that occurs comorbidly in patients with chronic inflammatory airway diseases, including asthma, chronic obstructive pulmonary disease (COPD), and asthma-COPD overlap syndrome (ACOS). However, the prevalence of osteoporosis in patients with ACOS has not widely been evaluated. Therefore, we investigated the prevalence of osteoporosis and its relationship with the clinical parameters of patients with asthma, COPD, and ACOS. Methods: This was a retrospective, cross-sectional study. Bone mineral density (BMD), lung function tests, and disease status evaluations were conducted. Results: A total of 321 patients were enrolled: 138 with asthma, 46 with ACOS, and 137 with COPD. One hundred and ninety-three patients (60.1%) were diagnosed with osteoporosis (53.6% of asthma, 65.2% of ACOS, and 65.0% of COPD). Patients with ACOS showed a significantly lower BMD and T-score than did those with asthma. In addition to age, sex, and body mass index (BMI), which were previously reported to be associated with BMD, BMD also had a negative correlation with the diagnosis of ACOS, as compared to a diagnosis of asthma, after adjusting for age, sex, BMI, smoking, and inhaled corticosteroid use (p=0.001). Among those patients with COPD and ACOS, BMD was negatively associated with the COPD Assessment Test (CAT) after adjustment (p<0.001). Inhaled corticosteroid was not associated with the prevalence of osteoporosis and BMD. Conclusion: Patients with ACOS, particularly aged and lean women, should be more carefully monitored for osteoporosis as compared to patients with asthma.

연구목적 본 연구는 일 종합병원 입원 환자를 대상으로 우울, 불안, 디스트레스 등을 비교 분석하여 자살 고위험군을 선별하고, 이들의 임상적 특징을 파악하고자 하였다. 방 법 일 종합병원에 2016년 1월로부터 2017년 12월까지 입원한 전체 환자를 대상으로 하여, 최종 41,249명의 정서상태, 통증, 기저질환 및 기능수준과 관련된 의무기록을 분석하였다. 정서상태 평가를 위해 디스트레스 온도계, 병원 불안-우울 척도를 사용하였다. 자살에 대한 고위험군은 디스트레스 온도계 점수 4점 이상이면서, 병원 불안-우울 척도의 불안, 우울 하위 척도 중 하나라도 8점 이상인 환자로 정의하였다. 결 과 대상자 중 자살에 대한 고위험군 기준에 부합하는 환자는 3,603명(8.7%)였다. 자살 고위험군은 일반군에 비해 더 심한 통증을 경험하고 있었으며, 기저질환을 가진 경우가 더 많은 것으로 나타났다. 통증을 보고한 환자들에서는 디스트레스 온도계 점수, 병원 불안-우울 척도의 불안, 우울 하위 척도 모두에서 통증이 없다고 보고한 환자들에 비해 더 높은 점수를 보였다. 결 론 자살 고위험군은 더 심한 통증과, 더 많은 기저질환을 갖는 것으로 나타났다. 따라서 입원 시 환자의 위험도에 따른 선별 및 선별된 환자들을 대상으로 하는 적극적인 자살 예방 방안이 필요하다.

Twenty-nine cases of unicameral bone cyst developed in long bone of children have been treated and followed up for 4.5 years in average form Department of Orthopaedic Surgery, Guro Hospital, Korea University, College of Medicine since September, 1983, Treatment for those lesions differed to form largely two groups, one of which consised of insillation of Methyl-prednisolone for non-weight bearing bones(12 humeri) and the other of curettage and autogenous bone graft for weight-bearing bones(7 femur). Methl-prednisolone group required repetition of instillation for 3.5 time in average spanning over 4 years until cloudy obliteration occurs. Curettage and bone graft had healed in 3 year 6 months' time in average. There were neither recurrence nor pathologic fractures of the lesions with the latter group. Immobilization period was virtually non with Methyl-prednisolone group and 4-6 weeks by hip spica with curettage and bone graft group. As conclusions, It seems confirmed that treatment strategy of unicameral bone cyst consisted of Methyl-prednisolone instillation for humerus lesions and early curettage and bone graft for femur lesions is applicable as guideline having solid ground in clinical experiences.

Statement of problems: There are few studies which reported the survival rates of the specific dental implant systems in the Korean population with the follow-up periods longer than 5 years. Purpose: This retrospective clinical study was aimed to evaluate cumulative survival rate (CSR) of $Br{\aa}nemark$ implants followed for 10 years and to determine risk factors for implant failure. Material and methods: A total of 271 $Br{\aa}nemark$ implants in 83 patients were investigated with several identified risk factors. Life table analysis was undertaken to examine the CSR. Cox regression method was conducted to assess the association between potential risk factors and overall CSR. Results: Thirty implants failed. The 10-year implant CSR was 82.5%. Cox regression analysis demonstrated a significant predictive association between overall CSR and implant length (P<.05). Conclusion: An acceptable long-term result of $Br{\aa}nemark$ implant was achieved and implant length showed a significant association with the CSR.

Spinal meningiomas typically adhere to the dura matter. Non-dural based spinal meningiomas are rare and most are clear cell meningiomas. We report here the first case of a fibrous meningioma with non-dural attachment. The patient was a 49-year-old female, who complained of numbness in the legs and a gait disturbance. Magnetic resonance imaging revealed a $1.7{\times}1.4-cm$ mass in the C7-T1 intra-dural extramedullary space, showing peripheral gadolinium enhancement without a "dural tail sign". A complete microsurgical resection was performed. The mass was covered with a white membrane but was not adhered to the dura, and its appearance was consistent with a neurilemmoma. The histopathological diagnosis was fibrous-type meningioma. The recovery of the patient was uneventful. No surgical complications and no recurrence of the tumor had occurred at the 6-month follow-up.

Orthognathic surgery is designed to correct problems of the jaw and face and restore facial harmony. The limitations of orthognathic surgery occur at all steps of the surgical workflow: preoperative planning, simulation, and operation. Many studies have shown the accuracy and advantages of 3 dimensional computer-assisted program for orthognathic surgery. The purpose of this paper is to introduce the accuracy of the maxillary repositioning in patients who underwent orthognathic surgery using a 3 dimensional computer assisted surgery program. The reliability of computer guided orthognathic surgery using splint and surgical guide need to be improved further. The 3 dimensional computer assisted analysis seems to be more precise to interpret than two-dimensional analysis. High-precision planning of orthognathic surgery has predictable results. Three-dimensional computer assisted orthognathic surgery has the following advantages : planned surgical movement is possible, splints guide with CAD/CAM technology; and increase predictable results .Computer assisted simulation surgery ensures accuracy during surgery, thereby facilitating predictable results. It may provide solution that enables surgeon to perform planned surgery more accurately.

Objective: The aim of this study was to compare the electrodiagnostic outcomes of carpal tunnel release in patients with and without diabetes with carpal tunnel syndrome (CTS), and to evaluate the effect of diabetes mellitus (DM) on electrodiagnostic outcomes. Method: We conducted a retrospective analysis of 67 patients with electro-diagnostic evidence of CTS. Patients were classified into two groups according to the presence of DM. Both groups were evaluated using nerve conduction studies preoperatively and 3 weeks and 3 months postoperatively. Results: There were no statistical differences in any of the electrodiagnostic parameters between groups 3 weeks postoperatively. However, there were statistical differences in the amplitude and the latency of compound muscle action potential, and sensory nerve conduction velocity 3 months postoperatively. Conclusion: Patients with DM did not show a significantly different outcome 3 weeks after surgery but showed a worse electrodiagnostic outcome 3 months after surgery than those without DM.
