In 1971 inclusion body myositis was reported by Yunis and Samaha. This disease is similar with chronic multiple myositis clinically. Pathologically, inclusion body myositis is characterized by intracytoplasmic vacuole with degenerating fibers and accompanied with inclusion body in internal nucleus and cytoplasm. Since then 240 cases of inclusion body myositis have been reported in the world including 3 cases in Korea. A 27 years-old lady had inclusion body myositis, which show slowly progressive muscular weakness. We confirmed this with clinical symptom, muscle biopsy, and electrophysiologic study. We report the typical manifestation of inclusion body myositis in a 27 years-old lady with the brief review of literature.

PURPOSE: Many patients who may be treated in primary care clinics resort to emergency centers during the off hours of such clinics. This may cause overcrowding of emergency centers and increased medical expenses. The aim of this study is to consider the optimal management of medical facilities for pediatric patients at night or on holidays. METHODS: The medical records of patients under the age of 16 years who had visited a pediatric emergency medical center during a two-year period between January 2012 and December 2013 were reviewed retrospectively. We examined how factors including the age group, disease/injury distinction, tentative diagnosis, use of the emergency medical service ambulances, and the final disposition of the patients varied depending on the availability of medical facilities. RESULTS: Among the 32,951 pediatric patients, approximately half visited the center on holidays (51.6%), and a quarter were injury patients (26.4%). Fever (38.8%) and head injury (16.1%) were the most frequent tentative diagnosis in diseases and injuries, respectively. More visits of infants and toddlers and disease patients occurred on days and hours of low medical service availability, and there were relatively few injury patients in the late night hours. CONCLUSION: These findings suggest that closing pediatric clinics around midnight is reasonable. More facilities operating at night and on holidays for pediatric patients are needed.

PURPOSE: The present study was conducted to determine and compare the target attainment rate (TAR) between microorganism-nonspecific (Ctrough) and microorganism-specific (AUC24/MIC) targets over two weeks of teicoplanin administration according to several dose regimens for the treatment of Staphylococcus aureus in Korean patients with neutropenic fever. MATERIALS AND METHODS: One thousand virtual concentrations were obtained for each dose using the population pharmacokinetic parameters of teicoplanin adopted from a published study. Simulation of 1,000 virtual MICs was performed using the MICs of 78 clinical isolates of S. aureus collected from a hospital in Korea. Thereafter, these simulated MICs were randomly allocated to 1,000 virtual patients in whom the TARs for AUC24/MIC >125 [or 345] and Ctrough >10 [or 20] mg/L were determined. The relationship of the maintenance dose with the steady-state TAR was predicted with respect to the AUC24/MIC >125 [or 345] using logistic analysis. RESULTS: The standard dose regimen of teicoplanin showed TARs of about 70% [or 33%] and 70% [or 20%] at steady-state in cases with AUC24/MIC >125 [or 345] and Ctrough >10 [or 20] mg/L, respectively. CONCLUSION: The current standard dose regimen was predicted to be insufficient to adequately treat S. aureus in Korean patients with neutropenic fever. To assure at least an 80% TAR in this population, dose adjustment of teicoplanin should be considered.

A case of Kaposi's sarcoma involving the small bowel two years after receiving a renal transplant is described. Immunosuppression had been achieved using cyclosporine A and prednisolone. Lesions extended from the duodenum to the ileum ; radiologically, they were demonstrated on small bowel follow-through study and computed tomography as multiple small nodular intraluminal masses with or without central umbilication, and endoscopically, were seen as intramural mucosal elevations with a central crater-like ulceration.

OBJECTIVE: To determine the effectiveness of electrical stimulation over the trunk in improving trunk control during early stroke rehabilitation. METHOD: Thirty-two acute and subacute hemiparetic stroke patients were enrolled in this study. All patients were randomly assigned to one of two groups, control group or electrical stimulation (ES) group. Both groups received the same physical therapy for 3 weeks. ES group received additional electrical stimulation over the posterior back muscles for 30 minutes a day, 5 days per week for 3 weeks. Outcome measurements included Korean version of Berg balance scale (K-BBS), total score of postural assessment scale for stroke patients (PASS), trunk control subscale of postural assessment scale for stroke patients (PASS-TC), trunk control test (TCT), Korean version of modified Barthel index (K-MBI), and motricity index (MI). These measurements were checked before and after treatment. RESULTS: There were no significant differences in the baseline characteristics and initial values between two groups. Following 3 weeks therapy, the changes of TCT and PASS-TC scores in the ES group were significantly higher than those of the control group (p <0.05). The changes of K-BBS, PASS, and K-MBI scores in the ES group tend to be higher than those in the control group. However the differences were not statistically significant. The changes of PASS-TC and TCT scores were significantly correlated with the changes of BBS and K-MBI scores at discharge. CONCLUSION: This study suggests that electrical stimulation over the trunk may be a beneficial therapeutic technique in improving trunk control in acute and subacute hemiparetic stroke patients.
