La mayoría son benignas, pero existe un pequeño porcentaje de casos de tumor de Brenner maligno, entre ellos el caso que se presenta. Se trata de una mujer de 41 años que presentó una tumoración ovárica cuyo resultado anatomopatológico fue de carcinoma pobremente diferenciado, con asociación de tumor tipo Brenner maligno. A pesar de ser diagnosticado en estadio precoz, este caso destaca por su mal pronóstico. PALABRAS CLAVE: Tumor de Brenner, cáncer de ovario, células transicionales, núcleos en "grano de café" SUMMARY Brenner tumor is a rare neoplasia, accounting for 1-2% of ovarian cancer. Most of them are benign, but there are a small percentage of malignant Brenner tumors, including the case presented. This is a 41-yearold woman who presented an ovarian tumor. Definitive histological result showed a poorly differentiated carcinoma, with association of malignant Brenner tumor. Despite being diagnosed in early stages, this case stands out for its poor prognosis.

There are discrepancies regarding prenatal management and postpartum treatment. Objective: To analyze prenatally diagnosed CCAM in our hospitals, in order to evaluate ultrasound findings with fetal and postnatal evolution. Patients and Method: Retrospective study of all cases diagnosed prenatally by ultrasound between 2005 and 2016 in two reference hospitals. The ultrasounds were performed using high-resolution ultrasound scanners, Toshiba Xario and Voluson 730 Expert Pro, with follow-up from diagnosis to delivery. The variables analyzed included gestational age at diagnosis, the characteristics of the lung lesion, associated malformations, cytogenetic study, the evolution of pregnancy, type of delivery, presence of respiratory distress, need for complementary imaging tests, pediatric clinical course, and necessary postnatal treatments. It was considered a resolution the total disappearance of the lesion in the prenatal ultrasound or that the postnatal chest X-ray showed no lesion. Results: 17 cases were prenatally diagnosed. The evolution ranges from the prenatal resolution of the lesion to the persistence after birth. Three patients voluntarily decided to have an abortion due to ultrasound findings of poor prognosis. Of the fourteen remaining cases there were no cases of fetal or neonatal deaths, one case required surgery after birth and four patients had mild symptoms during the first year of life. One case of false negative with neonatal death has been reported which necropsy reported as CCAM type 0. Conclusions: This pulmonary malformation presents good prognosis, excluding cases with fetal hydrops. Two-dimensional ultrasound is usually enough for diagnosis and follow-up. Computed tomography is the technique of choice to confirm the resolution of lesions after birth. Surgical treatment is preferable over conservative management, although it is unknown if the potential complications of this disease, even when asymptomatic, justify surgical morbidity.

Material and methods We performed a prospective study in 46 women who underwent 2D and 3D transvaginal scans successively. Three 3D volumes (uterus and each ovary) were acquired and evaluated 4 months later on a personal computer. We compared 2D and 3D scans in relation to sonographic diagnosis and biometry and the time spent. Results There was complete agreement between 2D and 3D techniques for sonographic diagnosis (31 normal exams, 16 adnexal cysts and seven myomas), except for the visualization and measurement of the uterine cervix. The mean time for 2D scans was 3.29 ± 1.32 minutes and was 2.96 ± 0.58 minutes for 3D examination (P = 0.076). The time required to acquire 3D volumes was only 1 hour, freeing 1 hour and 32 minutes for the performance of new scans. Conclusions Transvaginal 3D ultrasonogra...

Study design: We studied the Bishop score, cervical length and parity in 196 pregnant women in the prediction of successful vaginal delivery within 24 h of induction. Logistic regression and segmentation analysis were performed. Results: Cervical length (odds ratio (OR) 1.089, P<0.001), Bishop score (OR 0.751, P ¼ 0.001) and parity (OR 4.7, P<0.001) predict the success of labor induction. In a global analysis of the variables studied, the best statistic sequence that predicts the labor induction was found when we introduced parity in the first place. The success of labor induction in nulliparous was 50.8 and 83.3% in multiparous women (P ¼ 0.0001). Conclusions: Cervical length, Bishop score and parity, integrated in a flow chart, provide independent prediction of vaginal delivery within 24 h of induction.

The diagnosis of initial acute PID (acute salpingitis) begins with a challenge for the doctor, due to the little sensibility of the clinic's criteria. The accumulation of pus inside the fallopian tube gives a location for the tubaric abscess or pyosalpinx, whose characteristic signal is the presence of purulent material in considerable quantities and is visible by means of a sonograph inside the tubal light. We refer a series of characteristic sings that advise us.

Organochlorines (OCs) tend to accumulate in human tissues and can be measured in amniotic fluid (... more Organochlorines (OCs) tend to accumulate in human tissues and can be measured in amniotic fluid (AF). The detection of OCs in AF samples reflects intrauterine exposure of human beings to these persistent organic pollutants. The present study was performed to evaluate the level of contamination of AF by OCs in 100 pregnant women from Tenerife Island (Canary Islands, Spain). Gas chromatography/mass spectrometry (GC/MS) was used to identify and quantify the analytes, including 7 polychlorobiphenyl (PCB) congeners and 18 OC pesticides and metabolites. The majority of the AF samples (67%) showed some detectable OC-residue, hexachlorobenzene (HCB) being the most frequently detected compound (66% of the samples) and at the highest concentration (median 0.023 ng/ml). Lindane was also detected in 28% of the samples. Inverse associations were found between previous lactation and hexachlorocyclohexane isomers (HCH) and cyclodienes in the group of younger women (p ¼ 0.037 and p ¼ 0.027, respectively). Unexpectedly, serum values of HCB (r ¼ À0.414; p ¼ 0.04), g-HCH (r ¼ À0.294; p ¼ 0.035), and P OCs (r ¼ À0.350; p ¼ 0.014) were negatively related to age. Even more, women with detectable levels of HCH isomers were younger (33.974.9 years) than women with undetectable levels of them (36.174.9 years; p ¼ 0.035). We conclude that approximately one in two fetuses in the Canary Islands is exposed to OCs in utero, and that, therefore, the exposure of young women from these Islands to some HCH isomers persists nowadays. Because prenatal exposure to these chemicals may be a causative factor in adverse health trends, further studies are required to enhance preventive measures.

The precocity of the realization of sonographic explorations in the pregnancy will allow diagnosis of many more cases of spontaneous interruptions of the development of pregnancy. New sonographic imaging techniques including threedimensional (3D) sonography can provide additional information regarding the presence of structural anomalies via 3D volume acquisition, like craniofacial deformities, clefts, neural tube defects, abdominal wall defects, and caudal regression syndrome. It may give further details regarding the timing of embryonic/ fetal demise in early pregnancy. Sufficient informational value is regularly obtained in cases having a crown-rump length >8 mm.

Methods A prospective observational study was performed on a total of 1332 consecutive women admitted for delivery, during a 3 months period, in the public obstetric services of Tenerife Island (covering a population of 1 000 000 inhabitants). Results Less than 4% (3.6%) of the women recognised having a psychiatric disorder, and only 2.5% were receiving psychiatric drug treatment at the moment they knew they were pregnant; of those, 68.7% introduced substantial modifications in their treatment at that moment, 47.9% did not report any change with respect to the period before pregnancy and 35.4% recognised that their mood was worse than previously. Although patients affected by a psychiatric disorder registered a higher rate of abdominal delivery, no differences in delivery or obstetric complications were found between women with and without psychiatric illness or in relation to psychiatric drug treatment. Conclusions Compared to the literature, the studied population shows a lower rate of psychiatric problems and pharmacological treatment. This might reflect underrecognition or undertreatment.

In that respect, irregular cicatrization patterns can be identified from the early puerperium over the whole postparturition recovery period, and may encourage the need for further cesarean in new pregnancies to come. Subjects and Methods A random sample of 42 female patients were subjected to transvaginal sonographic exploration at three sampling times, namely 4 days, 4 months, and 1 year following hysterotomy. All of these women recovered successfully from their cesarean and were discharged from hospital 5 days after parturition. The 2D and 3D surveys were subsequently undertaken at each of the three study times. Four days after surgery, the 2D ultrasound scan aimed at evaluating the early evolution of the uterine scar. On the contrary, 3D echographies were implemented fram...
