BackgroundWe aimed to investigate the diagnostic utility of osteocalcin (OC), undercarboxylated osteocalcin (ucOC), and alkaline phosphatase (ALP) in pre- and postmenopausal women for femoral neck, L1-4, and L2-4 bone mineral density (BMD) values by taking into consideration their age, body mass index (BMI), and menopausal status.MethodsPremenopausal (N=40) and postmenopausal cases (N=42) were classified as 25-34 or 35-45 yr of age and within the first 5 yr or 5 yr or more after the onset of menopause, respectively.ResultsAmong the groups, statistical differences were found for age, BMI, OC, ucOC, ALP, femoral neck BMD, L1-4 BMD, and L2-4 BMD. The highest serum OC, ucOC, and ALP levels were observed in cases within the first 5 yr after the onset of menopause, probably due to a more rapid bone turnover rate. The best predictors for the femoral neck osteoporosis were ALP, OC, and calcium (areas under the ROC curve [AUC]=0.882, 0.829, and 0.761, respectively), and those for L1-4 and L2-4 osteoporosis were OC, ALP, and ucOC (AUC=0.949, 0.873, and 0.845; and 0.866, 0.819, and 0.814, respectively). Multiple logistic regression analysis revealed that the most discriminative parameter for osteoporosis was OC.ConclusionsThese results indicate that serum OC levels, with or without ucOC and ALP, may be useful to monitor follow-up changes that currently cannot be assessed with BMD and to diagnose femoral neck, L1-4 spine, and L2-4 spine osteoporosis.

In group B, H. pylori eradication rate was 91.25%, which is higher than the ideal 80% eradication rate. The results of the present study show that adding the prescribed doses of vitamins E and C to antimicrobial therapy is effective in eradicating H. pylori infection.

Determination of the liver histological lesions with noninvasive tests is an important part of the diagnostic work-up of patients with non-alcoholic fatty liver disease (NAFLD). We aimed to determine the predictive value of noninvasive biochemical markers, serum prolidase enzyme activity (SPEA), aspartate aminotransferase (AST), alanine aminotransferase (ALT), and AST/ALT ratio for the liver histological lesions. Fifty-four liver biopsy-proven patients with NAFLD and 37 healthy controls were enrolled to the study. The diagnostic accuracies of biochemical markers were evaluated by receiver operating characteristic (ROC) curves and multiple linear regression analysis to predict the degree of fatty infiltration, lobular inflammation, NAFLD activity score, and stage of fibrosis. The SPEA of patients with steatohepatitis is significantly increased compared with the patients with simple steatosis and controls (1,338 [1,138-1,624] U/l; 974 [768-1,160] U/l; 972 [862-1,122] U/l, shown as median [25th-75th interquartile range], respectively, P < 0.0001). SPEA was positively correlated with the grade of liver fatty infiltration, lobular inflammation and NAFLD activity score, and stage of fibrosis, (r = 0.377, P < 0.005; r = 0.443, P < 0.001; r = 0.457, P < 0.001; r = 0.321, P < 0.018, respectively). SPEA was the best predictor for distinguishing steatohepatitis from simple steatosis according to the ROC analysis (area under the curve [AUC]: 0.85). Multivariate analysis revealed that the most useful single test for predicting lobular inflammation, NAFLD activity score, and fibrosis was SPEA, and for predicting the fatty infiltration, it was ALT (P < 0.00001, P < 0.001, P < 0.0001, P < 0.0001, respectively). This study demonstrated that SPEA can accurately predict the degree and stage of all histological lesions in NAFLD. It could be helpful for distinguishing steatohepatitis from simple steatosis and reducing the need for liver biopsy in the majority of patients with NAFLD.

When compared with the available data on use of the conventional Limberg flap for PSD, our results suggest that use of the modified Limberg flap is associated with a lower maceration and recurrence rate, and greater patient satisfaction.
