Case ReportsSuspected anaphylactic reaction associated with microemulsion propofol during anesthesia induction.
Although rare, intraoperative anaphylaxis can lead to significant morbidity and mortality. Aquafol® (Daewon Pharmaceutical Co. Ltd., Seoul, Korea), a microemulsion propofol, was developed to eliminate lipid solvent-related adverse events, and was used in clinical anesthesia since 2009 with little data about severe side effects such as anaphylaxis. ⋯ Intravenous injection of epinephrine and steroid rescued him. He remained in a stable state without any problems postoperatively and was discharged. Clinicians should consider this rare but serious complication during induction of anesthesia with propofol.

Low handgrip strength is associated with low bone mineral density and fragility fractures in postmenopausal healthy Korean women.
Osteoporosis is a widely recognized health problem in postmenopausal women. Osteoporotic fractures reduce independency, limit daily living activities, and increase the mortality rate. Epidemiological studies have demonstrated that low handgrip strength is a risk factor for functional limitations and disabilities, and all-cause mortality. ⋯ Age and handgrip strength were associated with BMD of the spine, femur neck, and total hip in multiple regression models. Low handgrip strength (odds ratio [OR], 0.925; range, 0.877 to 0.975; P = 0.004) and low femur neck BMD (OR, 0.019; range, 0.001 to 0.354; P = 0.008) were independent predictors of previous fragility fractures in a multiple regression model. Our results demonstrate that low handgrip strength is associated with low BMD of the spine, femur neck, and total hip, and with increased risk of previous fragility fractures.

Spot urine albumin to creatinine ratio and serum cystatin C are effective for detection of diabetic nephropathy in childhood diabetic patients.
Spot urinary albumin to creatinine ratio (ACR) measurement has been suggested as a surrogate to 24-hr urine collection for the assessment of microalbuminuria, and cystatin C (cysC) is known as an advantageous marker for renal function. The aim of this study was to evaluate the clinical values of spot urinary ACR and serum cysC for the assessment of diabetic nephropathy instead of 24-hr urine microalbumin in children and adolescents with diabetes. A total of 113 children and adolescents (age 12-19 yr, M:F = 47:66) with type 1 or 2 diabetes were enrolled. ⋯ Spot urine ACR was correlated with 24-hr urine albumin excretion (R(2) = 0.828, P = 0.001) and creatinine clearance (R(2) = 0.249, P = 0.017). The ROC curve analysis of serum cysC demonstrated higher diagnostic accuracy than that of serum creatinine (AUC 0.732 vs 0.615). Both the measurements of spot urine ACR and serum cysC might better predict the presence of diabetic nephropathy than 24-hr urine microalbumin in childhood diabetic patients.

Differences in bone mineral density between the right and left hips in postmenopausal women.
Bone mineral density (BMD) using dual energy radiography absorptiometry are commonly used for the diagnosis of osteoporosis. It is usually measured at the spine and also at one hip joint. Controversy still exists regarding the use of bilateral hip scanning. ⋯ There were also discrepancies between the lowest T-scores of both hips (P < 0.05). The discordance rates were about 30%. Due to significant differences in BMD between both hips at the femoral neck and trochanter and high discordance rate, bilateral hip measurements using DEXA are recommended to avoid underestimating osteoporosis.

Comparative StudyFate of transplanted bone marrow derived mesenchymal stem cells following spinal cord injury in rats by transplantation routes.
This research was performed to investigate the differences of the transplanted cells' survival and differentiation, and its efficacy according to the delivery routes following spinal cord injury. Allogenic mesenchymal stem cells (MSCs) were transplanted intravenously (IV group) or intralesionally (IL group) at post-injury 1 day in rats. Behavioral improvement, engraftment and differentiation of the transplanted cells and the expression of neurotrophic factors of the transplanted groups were analyzed and compared with those of the control group. ⋯ The expressions of neuronal growth factor were significantly higher in the IL group (mean relative optical density, 2.4 ± 0.15) than those in the control (2.16 ± 0.04) or IV group (1.7 ± 0.23). Transplantation of MSCs in the early stage of spinal cord injury gives a significant clinical improvement. However, the fate of the transplanted MSCs and expression of neuronal growth factors are different along the transplantation route.
