Workshop for Basic Gynaecological Examinations: Improving Medical Student Learning through Clinical Simulation.

INTRODUCTION: This study was designed to evaluate whether the Workshop on Basic Principles for Clinical Gynaecological Exploration, offered to medical students, improves theoretical-practical knowledge, safety, confidence, global satisfaction and the achievement of the proposed objectives in the area of gynaecological clinical examinations. MATERIALS AND METHODS: This was a quasi-experimental pre-post-learning study carried out at the Gynaecology and Obstetrics department of Gregorio Marañón Hospital in Madrid (Spain). The volunteer participants were 4th-year students earning a degree in Medicine during the 2020-2021 and 2021-2022 academic years. The study period was divided into the following stages: pre-workshop, intra-workshop and 2 weeks post-workshop. In the pre-workshop stage, students completed a brief online course to prepare for the workshop. The effectiveness of the workshop was evaluated through multiple-choice tests and self-administered questionnaires to assess self-assurance, self-confidence, self-satisfaction and the achievement of the objectives. RESULTS: Of the 277 students invited in both academic years, 256 attended the workshop (92.4%), with a total participation in the different stages of the study greater than 70%. A total of 82.5% of the students in the 2020-2021 academic year and 80.6% of students in the 2021-2022 academic year did not have any type of experience performing gynaecological clinical examinations. Between the pre-workshop and 2 weeks post-workshop stages, there was significant improvement in theoretical-practical knowledge (improvement mean = 1.38 and 1.21 in 2020-2021 and 2021-2022 academic years, respectively). The security and confidence of the students prior to the workshop were low (average scores less than 5 points) in both academic years. However, post-workshop scores for satisfaction and the achievement of objectives were high in the two academic years; all the values approached or exceeded 8 points. CONCLUSIONS: Our students, after outstanding participation, evaluated the BPCGE, and improved their theoretical and practical knowledge, as well as their skills in a gynaecological clinical examination. Moreover, in their view, after the workshop, they felt very satisfied, far outreaching the proposed aims. In addition, excellent results were maintained over time, year after year.

Atosiban versus ritodrine as tocolytics in external cephalic version.

OBJECTIVE: To assess the efficacy of atosiban versus ritodrine as tocolytics in external cephalic version (ECV). MATERIALS AND METHODS: A prospective comparative trial was carried out in a tertiary hospital. 430 women with singleton breech pregnancies ≥36 weeks were recruited for ECV, 215 with ritodrine and 215 with atosiban as tocolytic agents. The efficacy, complications and perinatal outcomes were compared between both groups. The associations between variables were analyzed using the chi-square test (χ2) (qualitative), Student's t test (quantitative, parametric) or Mann-Whitney test (nonparametric). Statistical significance was established as p < .05. RESULTS: The overall ECV success rate was 47.9% (206/430), 46.0% in the atosiban group (99/215) and 49.8% in the ritodrine group (107/215). This difference showed no statistical significance (p = .440). A higher rate of uterine contractions after the maneuver was observed in the atosiban group (34.4 versus 22.8%; p = .008), but without clinical relevance. Perinatal outcomes were similar in both groups, with no significant differences. CONCLUSION: Atosiban and ritodrine showed similar efficacy as tocolytic agents in ECV, with no differences in complications and perinatal outcomes between these two agents.

Permeability of the amniotic membranes to the natural vanilla molecule.

Purpose: We studied natural vanilla permeability through amniotic membranes.Methods: We studied natural vanilla permeability through amniotic membranes obtained from 45 spontaneous normal deliveries at term. The ferric chloride test (FeCL3) was used to determine the presence or absence of phenols in a given sample. Vanilla is a polyphenol so it gives a reaction to FeCL3 with an intense color change. The diffusion of the vanilla was checked by dropping ferric chloride solution on the gauze once the membranes are lifted with care to avoid contamination. If vanilla has passed through the membranes the distilled water papers would change from an initial ferric yellow in the drops toward a marked gray/greenish color on the papers (positive test).Results: In all cases, the swabs were stained, all the membranes in both directions were permeable to the whole vanilla molecule.Conclusions: This experiment allows us to reevaluate the importance of molecular diffusion through the amniotic membranes with no placental metabolism existing between maternal and fetal environment.

Intrapartum and perinatal results associated with different degrees of staining of meconium stained amniotic fluid.

OBJECTIVE: To determine the intrapartum and perinatal results associated with different degrees of staining of meconium stained amniotic fluid (MSAF). STUDY DESIGN: In a retrospective cohort study of all singleton deliveries over a period of one year (2015) in a tertiary hospital, we compared different degrees of MSAF (yellow, green and thick) to clear amniotic fluids, and analysed in each group maternal, intrapartum and neonatal variables as well as umbilical cord blood gas analysis. RESULTS: Of the 3590 deliveries included, 503 (14%) had MSAF. The incidence of MSAF rises with gestational age at delivery, reaching 20.7% in gestations above 41 weeks compared to 4.3% below 37 weeks. As the amniotic fluid staining progresses we found a higher proportion of intrapartum fevers (p < 0.001), pathological fetal heart rate patterns (p < 0.05), operative vaginal deliveries and cesarean sections (p < 0.001), as well as the need for advanced neonatal resuscitation (p < 0.001). There was also a correlation between MSAF and low Apgar scores at five minutes (p < 0.001) and fetal-neonatal mortality (p < 0.001) but there was not a higher proportion of neonatal intensive care admissions (p > 0.05). We have observed a similar distribution of umbilical artery pH ranges in all groups (p > 0.05). CONCLUSIONS: MSAF was associated with an increase in the rate of pathological fetal heart rate patterns, intrapartum fevers, operative vaginal and cesarean section deliveries, need for neonatal resuscitation, low Apgar scores and higher fetal-neonatal mortality. Moreover, we found that the risks increase as the staining and consistency of the amniotic fluid evolves so it should alert the obstetrician and paediatrician to the potential adverse outcomes.

Diagnosis of a defect in the uterine wall using 3D ultrasound in the 16th week of gestation.

The 3D volumetric transabdominal study with rendering mode is a very useful tool to perform a detailed study of the uterine wall, and it allows us to create a safe and early strategy during pregnancy in uterine dehiscences, as we show in this case in the 16th week of gestation.

Accurate Diagnosis of Severe Hypospadias Using 2D and 3D Ultrasounds.

The hypospadias is the most common urogenital anomaly of male neonates but the prenatal diagnosis of this is often missed before birth. We present the prenatal diagnosis of a severe penoscrotal hypospadias using 2D and 3D ultrasounds. 3D sonography allowed us the best evaluation of the genitals and their anatomical relations. This ample detailed study allowed us to show the findings to the parents and the pediatric surgeon and to configure the best information about the prognosis and surgical treatment.

In utero gratification behaviour in male fetus.

Fetal masturbation has been described previously once in utero but only as a description of an action. Masturbation is well described in infancy and early childhood when they discover that this practice can give them pleasure. Our letter proves that it could begin in utero as a 'gratification behaviour'. We have shown this pattern clearly by using a volumetric rendering mode study. © 2016 John Wiley & Sons, Ltd.

Trombosis venosa cerebral recurrente en el embarazo / Recurrent cerebral venous thrombosis in pregnancy

La trombosis venosa cerebral es una enfermedad poco frecuente, pero de pronóstico potencialmente grave. Debido a los cambios hemostáticos durante la gestación, es una patología que puede asociarse al embarazo. Presenta un amplio rango de signos y síntomas. El diagnóstico y tratamiento precoz mejoran el pronóstico. Presentamos el caso de una mujer de 30 años, que en la semana 8 de gestación acude a Urgencias por cefalea intensa y cuya resonancia magnética reveló una trombosis venosa cerebral. La paciente presentó un segundo episodio en la semana 33, a pesar del correcto tratamiento anticoagulante recibido.

Cerebral venous thrombosis is a rare disease, but with a potentially serious prognosis. It is a condition that can be associated with pregnancy because of the hemostatic changes during gestation. It has a wide range of signs and symptoms. Early diagnosis and treatment improve prognosis. We report the case of a 30-year-old woman, at week 8 of pregnancy, who came to the emergency department for severe headache and whose magnetic resonance imaging revealed a cerebral venous thrombosis. The patient had a second episode at week 33, despite correct anticoagulation received.

Response of the foetal pupil to vibro-acoustic stimulation: a foetal attention test.

BACKGROUND: The iris regulates the intensity of light that stimulates the retina. The pupils dilate also in response to mental activities as sign of attention. We hypothesized that the response of the foetal pupil to vibro-acoustic stimulation (VAS) reflects foetal attention. AIMS: To determine whether the changes in the foetal pupil produced by vibroacoustic stimulation is a sign of foetal attention. STUDY DESIGN: We studied sonographically the pupils and iris of 151 foetuses between 27 and 41 weeks of gestation, using maximum ultrasonic zoom. SUBJECTS: 160 human foetuses between the 27th and the 41st week of gestation. OUTCOME MEASURES: The diameters of the pupil and iris were compared before and after VAS. RESULTS: At baseline, the pupils were miotic. We observed a response to VAS, manifest as a prominent pupillary dilatation in all foetuses. At all gestational ages, the percent increase in pupillary diameter was ≥57% (mean 87%; range: 57-135%). CONCLUSIONS: VAS dilated the foetal pupil. Sonographic assessment of the foetal pupil provided important insights in the development of foetal neurological functions.
