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.

Annals of Rehabilitation Medicine 2024;48(4):239-248
Objective:
To assess whether performing exercises during hemodialysis reduces the risk of developing intradialytic hypotension and enhances exercise capacity in patients with chronic kidney disease.
Methods:
This study included patients aged ≥18 years undergoing hemodialysis. Participants performed exercises using a portable lower extremity ergometer during hemodialysis sessions for 3 weeks. Data regarding walking distance, knee strength, quality of life, fat-free mass, arterial pressure, blood pressure, heart rate, frequency of intradialytic hypotension, fatigue, and duration of hemodialysis were collected and analyzed.
Results:
Significant improvements in walking distance and knee strength were observed following the implementation of exercise training during hemodialysis. Although there was no significant reduction in the frequency of intradialytic hypotension, a decreasing trend was noted. Other parameters such as quality of life and fatigue did not show significant changes.
Conclusion
Using a portable ergometer during hemodialysis improved exercise capacity and knee strength in patients with chronic kidney disease. There was a trend toward reduced intradialytic hypotension, suggesting potential cardiovascular benefits. Further research with larger sample sizes is needed to confirm these findings.

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.

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.

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.

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.
