Multiple studies have established that mild encephalitis/encephalopathy with a reversible splenial lesion (MERS) exhibits reversible diffusion restriction in the white matter, including the splenium. There have been a few previous reports of the change in fractional anisotropy (FA) of MERS cases. Herein, we report the longitudinal changes in axial and radial diffusivity (AD and RD), and FA in a 15-year-old boy patient with MERS. Our case demonstrated that a MERS lesion had a significant drop of AD in the early period and gradual recovery. On the contrary, RD did not show any significant change.

Leg amputation causes serious complications in walking and ultimately leads to functional impairment. Usually, the non-amputated side is considered as the dominant leg during prosthetic gait training. However, if the non-amputated side is affected by pathological conditions and has associated pain, it is necessary to determine whether it can be considered as the dominant leg. This case series presents four individuals who underwent leg amputations who also had pathologic conditions and pain in the non-amputated legs. A functional goal was established for each patient and individualized step-by step prosthetic gait training strategies were applied. Consequently, we found out that functional outcomes could be achieved even in cases with accompanying complications, such as fractures, nerve injuries, or pain, in the non-amputated leg.

BACKGROUND: Liver transplantation (LT) is a complicated procedure with a high incidence of postoperative acute kidney injury (AKI). Previous studies indicate that even transient or mild post-LT AKI can result in critical conditions, including prolonged stays in hospitals and intensive care units and increased morbidity and mortality. The aim of this study was to investigate the association between body mass index (BMI) and occurrence of AKI in LT recipients. METHODS: Medical data from 203 patients who received LT surgery from January 2010 to August 2016 in a single university hospital setting were retrospectively collected and analyzed. Patients were classified as either underweight (BMI <20 kg/m²) or normal weight (20 ≤ BMI < 30 kg/m²). Demographic data, anesthetic methods, complications, and perioperative laboratory test values of each patient were assessed. Propensity analyses and logistic regression were performed to evaluate the association between BMI and post-LT AKI. RESULTS: There was no significant difference in occurrence of post-LT AKI between underweight and normal weight patients. The underweight patient group had significantly longer hospital stay compared with the normal weight patient group (P = 0.023). CONCLUSIONS: BMI classification was neither a positive nor negative predictor of postoperative AKI occurrence. However, patients with lower BMI had significantly longer hospital stay compared with their counterparts. Although our study was limited by its retrospective design, our observations suggest that lower BMI might play a role in post-LT AKI.

INTRODUCTION: Guided bone regeneration (GBR) is a common procedure for the treatment of bone defects and bone augmentation. The non-resorbable barriers are well-documented barriers for GBR because of their stability and malleability. However, few GBR studies have focused on the different types of non-resorbable barriers. Therefore, this study examined the clinical results of different non-resorbable barriers for GBR; expanded polytetrafluoroethylene (e-PTFE) (TR-Gore Tex, Flagstaff, AZ, USA), and high-density polytetrafluoroethylene (d-PTFE) (Cytoplast membrane, Oraltronics, Bremen, Germany). MATERIALS AND METHODS: The analysis was performed on patients treated with GBR and implant placement from January 2007 to October 2007 in the department of the Seoul National University Bundang Hospital. The patients were divided into two groups based on the type of non-resorbable barrier used, and the amount of bone regeneration, marginal bone resorption after prosthetics, implant survival rate and surgical complication in both groups were evaluated. RESULTS: The implants in both groups showed high survival rates, and the implant-supported prostheses functioned stably during the follow-up period. During the second surgery of the implant, all horizontal defects were filled with new bone, and there was no significant difference in the amount of vertical bone defect. CONCLUSION: In bone defect areas, GBR with non-resorbable barriers can produce favorable results with adequate postoperative management. There was no significant difference in bone regeneration between e-PTFE and d-PTFE.

Purpose: There has been a lack of study on the pains of Korean archers, who have been getting remarkable results in international competitions. In this study, we investigated the epidemiology of shoulder pain, which is known as the most commonly complained symptom of Korean archers. Methods: The participants were 58 elite archers in the city of Gwangju, South Korea. The method of the study was a retrospective cohort study by questionnaire and ultrasound and physical examination. Variables of individual characteristics, training patterns, the character of pain were analyzed in different age groups. Furthermore, groups were divided into those with shoulder pain and those without pain to analyze each group’s shoulder function. Results: The most common injury was shoulder injury (65.6%), and hand injury was the second-highest prevalent injury (29.3%). These two injuries were most prevalent in all age groups. Among 58 participants, 40 showed shoulder pain, but most were mild (n=30, 51.7%) and severe pain was observed in some participants (n=2, 3.5%). Mild pain was most common in each group and it showed the highest prevalence in college students (70.0%). Pain was most observed in the drawing arm, and it was triggered most when drawing the bow. In the shoulder function test category, Constant-Murley score and American Shoulder and Elbow Surgeons score were observed the lowest in the group with shoulder pain with statistical significance. Conclusion Shoulder injury had a high prevalence in Korean archers. Correspondingly, those with shoulder pain had lower shoulder function test scores.

OBJECTIVES: To investigate the clinical effects of orthokeratology lens wear on inhibition of the myopic progression and axial length elongation in Korean children with myopia. METHODS: The authors reviewed out-patient records of 37 eyes of 19 patients wearing orthokeratology lenses. The 46 eyes of 23 patients wearing spectacles were included into the control group. We evaluated the relationship between orthokeratology lens wear and control group according to age, initial myopia, initial astigmatism, axial length elongation. RESULTS: There were no significant differences between two groups as for age, initial myopia, astigmatism, spherical equivalent, and axial length at baseline (t-test, P > 0.05). Significant reduction of refraction was shown in patients with wearing lenses after 1 year (t-test, P < 0.001). The mean axial length before and after 1 year was 24.62 ± 1.39 mm and 24.73 ± 1.28 mm respectively after lens wearing, and 24.59 ± 0.74 mm and 24.80 ± 0.71 mm respectively after wearing glasses. The axial length elongation was 0.11 ± 0.12 mm, and 0.21 ± 0.07 mm in patients with wearing lenses and glasses, respectively, which showed statistically significant difference (t-test, P < 0.0001). CONCLUSIONS: The orthokeratology lens was found to be effective in suppression of myopic progression through less axial length elongation, compared with the glasses.
