Our study showed that abnormal fetal presentation and multiparity are associated with an increased risk of umbilical cord prolapse. The association of risk of cord prolapse with low birth weight was statistically insignificant (P > 0.05). We suggest that the cesarean delivery decreased the risk of perinatal mortality among cases of cord prolapse.

FPG and hs-CRP in the first trimester are correlated with later development of GDM in the pregnancy. In our study, FPG provided a better sensitivity while hs-CRP exhibited a better specificity for prediction of GDM.

Although osteoporosis is reported as a potential complication of type 1 diabetes mellitus (DM), the effects of type 2 DM on bone mass are conflicting. Most of the studies conducted in recent years reveal that bone mineral density (BMD) values of type 2 DM patients are not decreased and even increased when compared with healthy control groups. In this study we evaluated bone turnover in 57 postmenopausal type 2 DM patients utilizing biochemical markers for bone formation and resorption, and BMD measurements. We found that BMD values in diabetic patients (0.91 +/- 0.11 g/cm(2) for lumbar region, 0.89 +/- 0.14 g/cm(2) for hip region) were higher than healthy postmenopausal control group (0.81 +/- 0.12 g/cm(2) for lumbar region, 0.76 +/- 0.10 g/cm(2) for hip region). Serum alkaline phosphatase values were similar to the control group, whereas serum osteocalcin and N-telopeptide/creatinine (NTx/Cr) values were significantly lower than the control group (osteocalcin: 8.82 +/- 4.03 ng/ml, NTx/Cr: 122.70 +/- 81.76 nMBCE/mMCr) in diabetic patients (osteocalcin: 4.44 +/- 3.53 ng/ml, NTx/Cr: 42.24 +/- 29.97 nMBCE/mMCr). Also a significant correlation was observed between body mass index and BMD values. Our findings suggested that the bone turnover rate is remarkably lower in type 2 DM patients compared to healthy postmenopausal patients.

Objective: The aim of this study was to evaluate predictive role of risk of malignancy index in discriminating between benign and malignant adnexal masses preoperatively. Methods: This retrospective study was conducted with a total of 569 patients with adnexal masses/ovarian cysts managed surgically at our clinic between January 2006 and January 2012. Obtained data from patient files were age, gravidity, parity, menopause status, ultrasound findings and CA125 levels. For all patients ultrasound scans were performed. For the assessment of risk of malignancy index (RMI) Jacobs' model was used. Histopathologic results of all patients were recorded postoperatively. Malignancy status of the surgically removed adnexal mass was the gold standard. Results: Of the total masses, 245 (43.1%) were malignant, 316 (55.5%) were benign and 8 (1.4%) were borderline. The mean age of benign cases was lower than malign cases (35.2±10.9 versus 50.8±13.4, p<0.001). Four hundred and five of them (71.2%) were in premenopausal period. Malignant tumors were more frequent in postmenopausal women (81% versus 29%, p<0.001). All ultrasound parameters of RMI were statistically significantly favorable for malignant masses. In our study ROC curve analysis for RMI provided maximum Youden index at level of 163.85. When we based on cutoff level for RMI as 163.85 sensitivity, specificity , PPV, NPV was calculated 74.7%, 96.2%, 94% and 82.6%, respectively. Conclusions: RMI was found to be a significant marker in preoperative evaluation and management of patients with an adnexal mass, and was useful for referring patients to tertiary care centers. Although utilization of RMI provides increased diagnostic accuracy in preoperative evaluation of patient with an adnexal mass, new diagnostic tools with higher sensitivity and specificity are needed to discriminate ovarian cancer from benign masses.

Basal magnesium levels in preterm labor had a predictive value in evaluating MgSO4 tocolysis response. It may help to select patients who are appropriate for MgSO4 tocolysis.

To the best of our knowledge, this is the first study evaluating the correlation between gestational age and fetal birth weight with such a large sample size in Turkey. Therefore, the results of this reference study can be helpful in defining normal and abnormal fetal growth in Turkish newborns.
