RESUMEN
AIM: The aim of this paper was to evaluate the lower uterine segment (LUS) thickness through transvaginal sonography in late preterm and full term pregnancies with a single previous Cesarean section, to correlate the obtained LUS measurements with intraoperative observations, and to identify a predictive cut-off value in order to select the best candidates for a vaginal birth after Cesarean delivery (VBAC). METHODS: Two hundred and fourteen women with a single previous Cesarean section who had an ultrasound measurement of the LUS thickness (stratified in S1, S2 and S3) in pregnancy were enrolled. The outcome of interest was the visual finding of a thin uterine scar at the time of the iterative Cesarean section. Linear regression was used to correlate the LUS thickness with gestational age (GA). A ROC curve has been used to determine the detection rate (DR) and the risk of each actual value of LUS thickness versus a thin uterine scar (outcome of interest). RESULTS: The LUS thickness was correlated with the gestational age (R2=0.034, P-value =0.005). The DR as estimated by ROC curves to detect a translucent lower uterine segment (S3) was 94.1% at a false positive rate (FPR) of 20%. The correspondent cut-off value was 1.8 mm. Finally a likelihood ratio (LR) of observing S3 was estimated. At the quoted cut-off of 1.8 mm the LR was 3. As demonstrated, for a segment of 1 mm the LR was instead about 13. CONCLUSION: The obtained values lead us to the conclusion that a thickness less than 1.8 mm can be reasonably considered a valid cut-off value to identify patients with a higher risk of thin uterine scar.

AIM: The study aims to calculate the probability of a successful vaginal delivery in post-term low-risk women by using a set of predictors (maternal, fetal, and ultrasonographic) according to the number of dinoprostone gel applications. METHODS: This was an observational study of a cohort of 174 low-risk post-term singleton pregnancies. Parity, cervical status and length, and amniotic fluid volume (AFI) were evaluated immediately before prostaglandin gel induction at the Department of Obstetrics and Gynecology, University of Bologna, Bologna, Italy between January 2010 and October 2011. RESULTS: A consistent difference in vaginal delivery rates was observed for women who had one gel administration (Group 1) versus those who received either two or three gel administrations (Group 2): 77.5% at 24 hours and 97.4% at 48 hours vs. 27% at 24 hours and 54% at 48 hours (P <0.001 for both the comparisons) respectively. The predictors of a vaginal delivery were cervix dilatation and short cervix for Group 1, lower AFI for Group 2, and parity for both groups. CONCLUSION: Women who require more than one gel administration have a lower rate of vaginal delivery at 24 and 48 hours. Maternal, fetal, and ultrasonographic parameters can predict a successful vaginal delivery.

The study is aimed at investigating the peculiarities of mobbing, as compared with other stress-related occupational issues, considering personal, occupational and health variables. A sample of 100 subjects examined in our Service was considered: 52 presented a situation ascribable to workplace bullying, 44 diseases associated with other occupational malfunctions, 4 were judged affected by psychic non work-related diseases. The two first samples do not differ as to main personal variables. Company reorganization is the most frequent event prior to work-related problems resulting into negative actions addressed towards the work, especially for workplace bullying. Both samples show impaired psychophysical conditions with a more serious depressive scenario for workplace bullying victims. This scenario can be associated with a more serious occupational situation and in particular victimization process.

OBJECTIVE: To investigate the ability of intrapartum translabial sonography to diagnose fetal station in the second stage of labor. METHODS: Patients with uncomplicated pregnancies at term gestation with fetuses in vertex presentation in the second stage of labor underwent serial translabial sonography and digital examinations. In a sagittal section of the maternal pelvis, the direction of the head was noted and categorized as downward, horizontal or upward. By rotating the transducer in the transverse plane the cerebral midline echo was also visualized and the rotation of the head was noted. Clinical and ultrasound data were compared using Somer's d-test. RESULTS: Sixty patients underwent a total of 168 clinical and sonographic examinations. When on the sonogram the fetal head was directed downward, the station assessed clinically was most frequently

The distribution of atrial natriuretic factor (ANF)-like immunoreactivity in the central nervous system of the cave salamander Hydromantes genei (Amphibia, Plethodontidae) was investigated by using antisera raised against rat and human ANF(1-28). Concurrently, the location of ANF-binding sites was determined by autoradiography, using radioiodinated human ANF(1-28) as a tracer. In several regions of the brain, including the olfactory bulb, the preoptic area, the ventral thalamus, the tectum of the mesencephalon, and the choroid plexuses inside the ventricles, a good correlation was observed between the distribution of ANF-immunoreactive elements and the location of ANF-binding sites. Mismatching was found in the habenular nucleus, the commissura habenularis, the fasciculum retroflexus, and the interpeduncular nucleus, which contained high levels of binding sites but were devoid of ANF-immunoreactive structures. In contrast, a few other regions, such as the pineal gland and the subcommissural organ, showed a high concentration of ANF-like immunoreactivity but did not contain ANF-binding sites. This study provides the first localization of ANF-like immunoreactivity and ANF-binding sites in the brain of an urodele amphibian. The results show that the ANF peptidergic system in the cave salamander has an organization more simple than the organizations described for the brain of frog or other vertebrates. This feature is probably related to the expression of highly pedomorphic characters in plethodontids. The anatomical distribution of ANF-immunoreactive elements and ANF-binding sites suggests that ANF-related peptides may act as hypophysiotropic hormones as well as neurotransmitters and/or neuromodulators in the salamander brain.

Cubebin, a dibenzylbutyrolactone lignan isolated from the crude hexane extract of the leaves of Zanthoxyllum naranjillo, showed a significant anti-inflammatory activity by using the paw edema induced by carrageenin in rats, but did not provide a significant reduction in the cell migration for the acute carrageenin-induced inflammatory reaction in the peritoneal cavity of rats. Neither was it effective in reducing the edema induced by dextran nor the edema induced by histamine. It partially reduced the edema induced by serotonin. Moreover, it significantly reduced the edema induced by prostaglandin PGE2 and the number of writhings induced by both acetic acid and PGI2 in mice. Therefore, it may be suggested that the mechanism of action of cubebin is similar to that observed for most of the non-steroidal drugs.

Acute phase proteins play an important role in clinical laboratory diagnosis, especially after recent development of quantitation methods. Turbidimetry and nephelometry, spectrophotometric procedures based on the quantitation of scattered and reflected light, permit laboratory analyses of higher precision, sensitivity and specificity compared to previously employed methods.

The authors showed that the colorimetric methods used to effect aminoacidopathies screening are inadequate and unspecific. The thin layer chromatography was chosen to effect such screening and the authors showed the incidence in newborns of some aminoacid metabolism abnormalities.
