Association between follicular fluid leptin and serum insulin levels in nonoverweight women with polycystic ovary syndrome.

AIMS: We evaluated the links between leptin and visfatin levels and fertilization rates in nonoverweight (NOW) women with PCOS (NOW-PCOS) from Apulia undergoing in vitro fertilization/embryo transfer (IVF). MATERIALS AND METHODOLOGY: We recruited 16 NOW women with PCOS (NOW-PCOS) and 10 normally ovulating NOW women (control-NOW). All women underwent IVF. Androgens, 17- ß -estradiol (17 ß -E2), and insulin levels were measured in plasma and/or serum and leptin and visfatin levels were assayed in both serum and follicular fluid (FF-leptin, FF-visfatin). RESULTS: In NOW-PCOS, both serum and FF-leptin were significantly lower than in control-NOW. In NOW-PCOS, significant correlations were found between BMI and serum leptin and insulinemia and FF-leptin. By contrast, in control-NOW, FF-leptin levels were not correlated with insulinemia. Serum visfatin levels were not significantly different in NOW-PCOS and control-NOW, but FF-visfatin levels were 1.6-fold higher, although not significantly, in NOW-PCOS than in control-NOW. CONCLUSIONS: Both serum leptin levels and FF-leptin are BMI- and insulin-related in Southern Italian NOW-PCOS from Apulia. In line with other reports showing that FF-leptin levels are predictive of fertilization rates, lower than normal FF-leptin levels in NOW-PCOS may explain their lower fertilization rate and this may be related to the level of insulin and/or insulin resistance.

The impact of lymph vascular space invasion on recurrence and survival in patients with early stage endometrial cancer.

The aim of this study was to determine impact of lymph vascular space involvement (LVSI) on recurrence and survival in early stage of endometrial cancer. From 1991 through 2010, all endometrial cancer patients at University Hospital of Bari, Italy were identified. The Log-rank test and Kaplan-Meyer methods were used for time-to-event analysis to evaluate the effects of on lymph vascular space involvement recurrence rate and survival time. Of the 560 endometrial cancer patients, 525 underwent primary surgery. Of those, 399 had early stage disease. Three hundred and forty women were not found to have LVSI, whereas 59 were found to have lymph vascular space involvement. Forty-nine (12%) patients developed a recurrence and 20 of them showed lymph vascular space involvement. The statistical analysis demonstrated that LVSI was strongly associated with a poor survival (P < 0.0001). Lymph vascular space involvement is associated with a high risk of recurrence and poor overall survival in early stage of endometrial cancer; therefore, the clinical decision to decide whether or not a patient with early stage endometrial cancer should receive adjuvant therapy should be included the evaluation of lymph vascular space involvement.

Social determinants of the increasing caesarean section rate in Italy.

AIM: Consistent modifications of socio-economic factors may represent crucial non-clinical determinants for the rising rate of caesarean section among primiparae. This increasing trend has been reported in many countries and its relationship with social modifications is widely accepted, though poorly supported by published data. METHODS: Population-based social and economic data were analyzed between two study periods 30 years apart (1971 vs 2001). RESULTS: The number of births dropped dramatically within the study period (about -40%). Italian women tend to delay childbearing (25.1 vs 28.8 years of age at first delivery) to pursue a career and a later marriage and motherhood lead to a contraction of the number of members of the family. Older mothers are at higher risk of caesarean (treble over 40 years of age), especially those with high career position. Health expenditures increased significantly between 1971 and 2001. A progressive contraction of the number of women in reproductive age is expected in the next 50 years in Italy. CONCLUSION: Many determinants are involved in the choice of a caesarean section and most of these are not strictly medical. The rapidly mounting number of legal claims may indeed lead to defensive practices. Given these data, a reduction of caesarean section rate seems unlikely to be achieved at present.

Estimation of fetal weight by measurement of fetal thigh soft-tissue thickness in the late third trimester.

OBJECTIVE: The accuracy of current formulae for the sonographic estimation of fetal weight (EFW) is compromised by significant intra- and interobserver variability of biometrical measurements, particularly circumferences. The aim of this study was to assess the reliability of the linear measurement of mid-thigh soft-tissue thickness (STT) and to derive a novel formula for EFW. METHODS: This was a prospective study involving 388 singleton uncomplicated pregnancies. There were three consecutive phases: (1) to verify the relationship between STT and birth weight, (2) to derive a novel formula for EFW using femur length and STT only, and (3) to test the accuracy of the new equation. Only the 290 patients who delivered within 48 h of measurement were considered for the analysis. A comparison with other formulae was performed. RESULTS: STT was significantly correlated with both abdominal circumference and birth weight (r(2) = 0.36 and 0.46, respectively; P < 0.001). Both intra- and interobserver variability were satisfactory (0.44 +/- 0.27 and 0.57 +/- 0.35 mm, respectively). The equation for EFW was developed using multiple stepwise regression analysis (EFW = - 1687.47 + (54.1 x femur length) + (76.68 x STT)) and tested prospectively on 69 patients. The new formula yielded results (r = 0.79) that were slightly better in accuracy than two other published equations, and had an absolute mean error of < 15% in 97% of cases. CONCLUSIONS: Our findings confirm the potential of the linear measurement of mid-thigh STT as a valuable parameter for the sonographic assessment of fetal growth and EFW. Our new equation is apparently at least as reliable as the most widely used formulae for EFW.

Abnormal cervical PAP smear leading to the diagnosis of gastrointestinal cancer without cervico-vaginal metastases.

We report the case of an unsuspected G.I. cancer in a patient with no clinical signs other than ascites and positive PAP-smear on admission. Histologically, neither endometrium nor cervix were involved. To date, only 2 cases of primary gastrointestinal (gastric) cancers with no metastases to the cervix, suspected by PAP-smear, have been reported in medical literature. A few more have been reported with cervical metastases. The suspicion of intraabdominal adenocarcinoma was based on the evidence of signet ring cells found in the smear with negative cervical biopsies and negative fractional curettage. A postmortem examination confirmed the absence of genital involvement. Our aim is to remind the clinician that an abnormal PAP-smear, due to non gynecological malignancies, can, on rare occasions, be observed. In order to obtain a positive cervico-vaginal PAP-smear by a non gynecologic intraabdominal exfoliating cancer, both previous literature and our case suggest peritoneal effusion to be of major importance.
