OBJECTIVE: Bone mineral loss in the upper extremity of hemiplegic patients can increase the prevalence of fractures that interrupt the rehabilitation program and lower the level of activity. The aim of this study was to investigate any difference between the affected and unaffected forearm's bone mineral density (BMD) and evaluate the relationship between several clinical variables and osteoporosis of hemiplegic forearm. METHOD: Sixty-seven hemiplegic patients (42 males, 25 females, mean age 55.2 years) were enrolled. The BMD of radius was measured using dual energy X-ray absorptiometry in 67 hemiplegic subjects. RESULTS: The BMD of affected forearm was significantly lower than unaffected side (p<0.05). The reduction of BMD in the hemiplegic forearm well correlated with duration of hemiplegia, self care of functional independence measure score, complex regional pain syndrome-type 1 (CRPS-1) (p<0.05). But, there was no correlation between BMD and modified Ashworth scale, muscle power of wrist extension. CONCLUSION: Hemiplegic forearm had high prevalence of osteoporosis like lower extremity. Therefore, increasing level of ADL and early detection of CRPS-1 was necessary for prevention of osteoporosis of forearm.

Toxoplasmic encephalitis (TE) is the most common cause of opportunistic central nervous system infection in advanced acquired immunodeficiency syndrome (AIDS) patients. The incidence of TE has fallen markedly after the availability of highly active antiretroviral therapy and cotrimoxazole chemoprophylaxis. TE linked to AIDS is a rare entity in Korea, but we must consider TE in the differential diagnosis of the opportunistic infections in AIDS patients. We report a case of toxoplasmic encephalitis in an advanced AIDS patient presenting as progressive right facial palsy.

OBJECTIVE: To document our experience of the vascular anomalies or variants in paraaortic region and intend to increase vigilance among the gynecological surgeons for presence of variable vascular anomalies or variants. METHODS: We conducted a retrospective chart review of 280 patients with various gynecologic malignancies who had undergone systemic laparotomic or laparoscopic paraaortic lymphadenectomy between November 2003 and July 2011. RESULTS: We discovered total nine patients of vascular anomalies during the surgery. Seven patients had an accessory polar renal artery. One patient had a duplicated inferior vena cava and the other had a right paravertebral vein. There were no vascular complications such as tearing, ligation or transection. CONCLUSION: It is not uncommon to encounter vascular anomalies in paraaortic region during the lymphadenectomy. Hence, the gynecological surgeons must be cognizant of various vascular anomalies occurring within this area to reduce the vascular accidents.

Purpose: Pelvis fractures are associated with bladder and urethral injury (BUI). The purpose of this study was to identify risk factors associated with BUI in patients with pelvic fracture. Methods: Patients (> 18 years) with pelvic injury (N = 314) at our hospital between January 2015 and June 2020 were retrospectively analyzed for age, sex, cause of injury, initial vital signs, urine red blood cell (RBC) count, Glasgow Coma Scale and Abbreviated Injury Scale score, Injury Severity Score, preperitoneal pelvic packing, and femur, lumbar spine, and pelvic fractures. Results: Compared with the BUI-absent group, the BUI-present group had a greater percentage of patients who were male (79.2% vs. 55.9%; p = 0.026), had a urine RBC count/high power field (HPF) ≥ 30 (94.4% vs. 38.8%; p < 0.001), underwent preperitoneal pelvic packing (37.5% vs. 18.6%; p = 0.035), had symphysis pubis diastasis (33.3% vs. 11.7%; p = 0.008), and had sacroiliac joint dislocation (54.2% vs. 23.4%; p = 0.001). Independent risk factors associated with BUI were symphysis pubis diastasis [odds ratio (OR) was 3.958 (95% confidence interval: 1.191–13.154); p = 0.025] and a urine RBC count/HPF ≥ 30 [OR = 25.415 (95% confidence interval: 3.252–198.637); p = 0.006]. Of those with BUI, 15 patients were diagnosed at the trauma bay, and 9 had a delayed diagnosis. Conclusion Patients with pelvic injury who display symphysis pubis diastasis or have a urine RBC count/ HPF ≥ 30 are at higher risk of BUI, therefore, further BUI investigations should be considered.

BACKGROUND: Non-alcoholic fatty liver disease is the most common form of chronic liver disease in industrialized countries. Recent studies have highlighted the association between peroxisomal dysfunction and hepatic steatosis. Peroxisomes are intracellular organelles that contribute to several crucial metabolic processes, such as facilitation of mitochondrial fatty acid oxidation (FAO) and removal of reactive oxygen species through catalase or plasmalogen synthesis. Statins are known to prevent hepatic steatosis and non-alcoholic steatohepatitis (NASH), but underlying mechanisms of this prevention are largely unknown. METHODS: Seven-week-old C57BL/6J mice were given normal chow or a methionine- and choline-deficient diet (MCDD) with or without various statins, fluvastatin, pravastatin, simvastatin, atorvastatin, and rosuvastatin (15 mg/kg/day), for 6 weeks. Histological lesions were analyzed by grading and staging systems of NASH. We also measured mitochondrial and peroxisomal FAO in the liver. RESULTS: Statin treatment prevented the development of MCDD-induced NASH. Both steatosis and inflammation or fibrosis grades were significantly improved by statins compared with MCDD-fed mice. Gene expression levels of peroxisomal proliferator-activated receptor α (PPARα) were decreased by MCDD and recovered by statin treatment. MCDD-induced suppression of mitochondrial and peroxisomal FAO was restored by statins. Each statin's effect on increasing FAO and improving NASH was independent on its effect of decreasing cholesterol levels. CONCLUSION: Statins prevented NASH and increased mitochondrial and peroxisomal FAO via induction of PPARα. The ability to increase hepatic FAO is likely the major determinant of NASH prevention by statins. Improvement of peroxisomal function by statins may contribute to the prevention of NASH.

Mitochondrial dysfunction and endoplasmic reticulum (ER) stress are considered the key determinants of insulin resistance. Impaired mitochondrial function in obese animals was shown to induce the ER stress response, resulting in reduced adiponectin synthesis in adipocytes. The expression of inducible nitric oxide synthase (iNOS) is increased in adipose tissues in genetic and dietary models of obesity. In this study, we examined whether activation of iNOS is responsible for palmitate-induced mitochondrial dysfunction, ER stress, and decreased adiponectin synthesis in 3T3L1 adipocytes. As expected, palmitate increased the expression levels of iNOS and ER stress response markers, and decreased mitochondrial contents. Treatment with iNOS inhibitor increased adiponectin synthesis and reversed the palmitate-induced ER stress response. However, the iNOS inhibitor did not affect the palmitate-induced decrease in mitochondrial contents. Chemicals that inhibit mitochondrial function increased iNOS expression and the ER stress response, whereas measures that increase mitochondrial biogenesis (rosiglitazone and adenoviral overexpression of nuclear respiratory factor-1) reversed them. Inhibition of mitochondrial biogenesis prevented the rosiglitazone-induced decrease in iNOS expression and increase in adiponectin synthesis. These results suggest that palmitate-induced mitochondrial dysfunction is the primary event that leads to iNOS induction, ER stress, and decreased adiponectin synthesis in cultured adipocytes.

“Clinical Practice Guideline for Stroke Rehabilitation in Korea 2016” is the 3rd edition of clinical practice guideline (CPG) for stroke rehabilitation in Korea, which updates the 2nd edition published in 2014. Forty-two specialists in stroke rehabilitation from 21 universities and 4 rehabilitation hospitals and 4 consultants participated in this update. The purpose of this CPG is to provide optimum practical guidelines for stroke rehabilitation teams to make a decision when they manage stroke patients and ultimately, to help stroke patients obtain maximal functional recovery and return to the society. The recent two CPGs from Canada (2015) and USA (2016) and articles that were published following the 2nd edition were used to develop this 3rd edition of CPG for stroke rehabilitation in Korea. The chosen articles' level of evidence and grade of recommendation were decided by the criteria of Scotland (2010) and the formal consensus was derived by the nominal group technique. The levels of evidence range from 1++ to 4 and the grades of recommendation range from A to D. Good Practice Point was recommended as best practice based on the clinical experience of the guideline developmental group. The draft of the developed CPG was reviewed by the experts group in the public hearings and then revised. “Clinical Practice Guideline for Stroke Rehabilitation in Korea 2016” consists of ‘Chapter 1; Introduction of Stroke Rehabilitation’, ‘Chapter 2; Rehabilitation for Stroke Syndrome, ‘Chapter 3; Rehabilitation for Returning to the Society’, and ‘Chapter 4; Advanced Technique for Stroke Rehabilitation’. “Clinical Practice Guideline for Stroke Rehabilitation in Korea 2016” will provide direction and standardization for acute, subacute and chronic stroke rehabilitation in Korea.
