Membranous lipodystrophy is a peculiar type of fat necrosis, present in patients with various types of skin diseases. It is charaeterized by the presence of microcysts and macrocysts lined by amorphous eosinophilic material with a crenelated arabesque appearance and microgranules in the subcutis with massive fat necrosis. The eosinophilic lining and microgranules stain positively with periodic acid-Schiff, are resistant to diastase, and also stain with Sudan black B. We report three cases of subcutanous membranous lipodystrophy in patients with erythema induratum, posttraumatic panniculitis and morphea with typical clinical and histopathologic findings.

Eosinophilic panniculitis is characterized by a prominent infiltration of numerous eosinophils in subcutaneous fat, and has been identified in patients with a variety of associated clinical conditions. A case of eosinophilic panniculitis in a 20-year-old woman with a history of atopic dermatitis is reported. She later developed superior sagittal sinus thrombosis, and we stress the importance of systemic evaluations in patients with eosinophilic panniculitis.

Purpose: Genu valgum in Legg-Calve-Perthes disease (LCPD) is not a known complication. We investigated whether this valgus tendency is a complication of femoral varus osteotomy (FVO) or the sequela of the disease process itself, and what are the related factors. Materials and Methods: 35 patients treated by FVO and 38 by abduction orthosis (AO) were selected for this study. Only those patients with unilateral involvement, fragmentation stage, Catterall Group III or IV, and who were followed-up to full skeletal maturity were included in the study. We measured mechanical axis deviation percentage and hip-knee-ankle angle for femorotibial alignment, and mechanical lateral distal femoral angle and medial proximal tibial angle (mMPTA) for knee orientation on teleoroentgenograms and compared the affected and normal limbs. Results: All measurements, excluding the mMPTA, demonstrated a tendency of relative genu valgum versus the opposite normal limbs. This tendency was observed in both groups. There was no statistically significant difference between the two groups. Conclusion: Genu valgum occurred in 66% to 70% of the LCPD patients. Four factors were found to be significantly correlated with valgus shift: increased medial bowing of the femoral neck, decreased acetabulum head index, coxa magna, and limb shortening. Multivariate regression analysis identified limb shortening as the factor most responsible for valgus shift.

Purpose: This study examined the effects of a physical stability exercise program on the functional movement and balance of middle school volleyball players to provide future management and training data to improve the performance of volleyball players. Methods: The subjects were 20 volleyball players from Y Middle School in Mokpo. The results of comparing and analyzing the effects of the physical stability exercise program on the functional movement and balance of middle school volleyball players for 10 weeks are as follows. Results: The number of participants who showed power and agility (p<0.01) was increased significantly, and the response time was shortened significantly (p<0.01). On the evaluation of functional movement, the total score showed a significant difference between the pre-test at 10.90±1.30 points and the post-test at 13.81±.60 (p<0.001). The subjects’ balance showed a significant difference from 84.11±7.53 to 97.65±8.47 (p<0.001), and the Right Composite Score showed a significant difference from 83.74±6.64 to 97.27±8.48 (p<0.001). Conclusion The application of a physical stability exercise program for 10 weeks is effective in improving the speed, agility, functional movement, and balance to volleyball players who are weakened and at risk of injury. This is believed to prevent or reduce injury.

Background/Aims: New direct-acting antivirals have shown surprising success in the treatment of hepatitis C, not only in the general population, but also in difficult-to-treat cohorts. However, there is still limited data regarding direct-acting antivirals, including sofosbuvir (SOF), in the context of hemodialysis. The aim of this study was to investigate the safety and outcome of administering full-dose SOF (400 mg/day) plus low-dose ribavirin (RBV, 100 to 200 mg/day) in hemodialysis patients with hepatitis C virus (HCV) genotype 2 (GT2) infection. Methods: Patients with chronic HCV GT2 infection and end-stage renal disease on maintenance hemodialysis treated with full-dose SOF plus low-dose RBV were retrospectively identified from a database of patients with HCV GT2 who were treated in Konkuk University Chungju Hospital between February 2017 and February 2018. Medical records were reviewed for demographics, medical history, laboratory data, and radiologic and electrocardiographic findings. Results: All nine patients completed a full course of 12 weeks of treatment with a full-dose SOF plus low-dose RBV regimen. Two had compensated cirrhosis. Seven patients were treatment-naïve, and two had a relapse following previous interferon-based therapy. All patients had a sustained viral response at 12 weeks post-treatment. There was no discontinuation of treatment because of side effects. Conclusions In hemodialysis patients with HCV GT2 infection, the full-dose SOF plus low-dose RBV regimen appears to be safe and well tolerated, and yields high rates of sustained virologic response.
