Effect of simulation-based training on the accuracy of fetal head position determination in labor.

OBJECTIVES: The objective of this study was to evaluate the effect of simulation-based training on the accuracy of fetal head position determination by junior residents during the second stage of labour. STUDY DESIGN: This prospective study was conducted in a tertiary care university hospital. During an initial period of 12 weeks, 13 junior residents were asked to routinely evaluate fetal head position by digital examination during the second stage of labour, in women with term singletons in cephalic presentation. Digital examination was followed immediately by transabdominal ultrasound to confirm fetal head position, performed by an experienced physician. Following this initial period, all participants attended a workshop where simulation-based training of fetal head position determination was provided. A second 12-week period was subsequently completed, with similar characteristics to the initial one. The accuracy of clinical evaluations was assessed by the percentage of exact evaluations, the percentage of correct evaluations within a 45° error margin, and by Cohen's kappa coefficient of agreement. RESULTS: A total of 83 observations were performed in the initial period of the study and 74 observations were performed in the second period. The accuracy of fetal head position determination during the first period of the study was 59.0% (95% CI 47.7-69.7), k = 0.517 (95%CI 0.391 - 0.635), corresponding to a moderate agreement. Considering a 45° margin of error, accuracy was 71.1% (95% CI 60.1-80.5), k = 0.656 (95% CI 0.538 - 0.763), corresponding to substantial agreement. Following simulation-based training, the accuracy of fetal head position determination was 70.3% (95% CI 58.5-80.3), k = 0.651 (95% CI 0.526 - 0.785), corresponding to a substantial agreement. Considering a 45° margin of error, accuracy was 78.4% (95% CI 67.3-87.1), k = 0.745 (95% CI 0.631 - 0.854), corresponding to a substantial agreement. CONCLUSIONS: Although a trend towards increased accuracy in fetal head position determination was observed after simulation-based training, the difference was not statistically significant. Further studies are needed to clarify the role of simulation-based training for fetal head position determination during residency.

Abdominal Wall Endometriosis Excision with Mesh Closure - Report of Two Cases.

Abdominal wall endometriosis (AWE) is a rare condition included in the differential diagnosis of an abdominal wall mass and/or pelvic pain in women of reproductive age. It usually occurs after pelvic surgery, most commonly caesarean section. Given the variable clinical presentation, diagnosis can be challenging if a high index of suspicion for AWE does not exist. Consequently, the correct diagnosis is often missed in the preoperative assessment. The presence of endometriosis in other locations can aid in the diagnosis, but other endometriotic lesions do not always exist. Image studies, particularly ultrasound and magnetic resonance imaging, can also be of help in the differential diagnosis. Even though new management techniques such as ultrasound-guided percutaneous cryoablation seem to be promising, surgical excision is still the mainstay of treatment. When the aponeurosis is involved, lesion excision might need to be followed by wall closure with the use of a mesh to lessen tissue tension. We present two typical cases of AWE after caesarean section, one of them recurrent, in patients with concurrent endometriosis of other locations. Total lesion excision followed by polypropylene mesh closure has been performed, with very good post-operative outcomes. We aim to raise awareness towards this diagnosis and to highlight the importance of complete lesion excision and adequate closure of the abdominal wall.

Laparoscopic Vaginal-Assisted Hysterectomy With Complete Vaginectomy for Female-To-Male Genital Reassignment Surgery.

STUDY OBJECTIVE: Total hysterectomy with bilateral salpingo-oophorectomy and vaginectomy for genital reassignment surgery is a complex procedure that is usually performed with a combined vaginal and abdominal approach. The aim of this study was to describe the feasibility of laparoscopic vaginectomy in sex reassignment surgery. METHODS: We reviewed the relevant medical history, intra/postoperative complications, and surgical results of all patients diagnosed with gender dysphoria and submitted to totally laparoscopic gender confirmation surgery in our department between January 2007 and March 2015. In total, 23 patients underwent total hysterectomy with bilateral salpingo-oophorectomy and vaginectomy in a single intervention. The vaginal mucosa was conserved to be used for the penile neourethra during the subsequent phalloplasty. MEASUREMENTS AND MAIN RESULTS: The surgeries had an average operating time of 155 ± 42 minutes. No intraoperative complications were registered. In all patients, the vagina was totally removed, and, in most cases (n = 20), we were able to remove laparoscopically more than 50% of the vagina. Three patients had postoperative complications. One patient presented with hemoperitoneum on the second postoperative day; another presented with prolonged urinary retention, and a third patient developed a perineal hematoma 1 month after surgery. Patients were discharged less than 72 hours after surgery, except the patient who developed a postoperative hemoperitoneum. For all patients, we obtained an adequate specimen of vaginal mucosa to reconstruct the penile neourethra for the subsequent phalloplasty. CONCLUSION: This study suggests the feasibility of laparoscopic vaginectomy in genital reassignment surgery. The procedure can be executed as a continuation of the hysterectomy with the potential advantage of the laparoscopy providing better exposure of the anatomic structures with low blood losses (less than 500 mL) and few complications. Furthermore, using this approach, adequate-sized vaginal mucosa flaps were obtained for the urethral reconstruction.

Prevalence and Risk Factors for Iron Deficiency Anemia and Iron Depletion During Pregnancy: A Prospective Study.

INTRODUCTION: Anemia and iron deficiency during pregnancy are a worldwide concern and are more frequent among women of reproductive age, pregnant women, and young children. The aim of this study was to assess the prevalence of iron deficiency anemia and the risk factors for iron depletion during the first half of pregnancy, in a Portuguese population. MATERIAL AND METHODS: A prospective study was conducted at a tertiary hospital and included pregnant women, until the 20th week of gestation. Data was collected regarding demographic and pregnancy features and hemoglobin and serum ferritin concentrations were determined. A multivariate logistic regression was performed to identify potential risk factors for iron deficiency. RESULTS: Two hundred and one women were included, from which five (2.49%) presented anemia. Additionally, 77 (38.3%) exhibited iron deficiency and 22 (10.9%) revealed severe iron depletion. Maternal age was the only risk factor identified. The odds ratio (OR) was equal to 12.99 (95% CI 2.41 - 70.0) for women under twenty years of age and 2.09 (95% CI 1.05 - 4.14) for women older than thirty years of age. DISCUSSION AND CONCLUSION: The prevalence of maternal anemia in the first half of pregnancy was lower than in other studies. However, more than one-third of the women exhibited iron deficiency. With the exception of maternal age, no other risk factors were identified.

Introdução: A anemia e a carência de ferro são problemas de saúde globais e são mais frequentes em grávidas, mulheres em idade reprodutiva e crianças. O objetivo deste trabalho consistiu na avaliação da prevalência de anemia ferropénica e dos fatores de risco associados à ferropénia, na primeira metade da gravidez, numa amostra da população portuguesa. Material e Métodos: Estudo prospetivo, conduzido num hospital terciário, que incluiu grávidas até à 20ª semana de gestação. Foram coletados dados demográficos, relativos à gravidez e foram determinados os níveis séricos de hemoglobina e de ferritina no sangue materno. Recorreu-se à análise de regressão logística de variáveis múltiplas para identificar potenciais fatores de risco para ferropénia. Resultados: Foram incluídas 201 grávidas, das quais cinco (2,49%) tinham anemia. Para além disso, 77 grávidas (38,3%) tinham carência de ferro e 22 (10,9%) apresentaram ferropénia grave. A idade materna foi o único fator de risco identificado. O odds ratio foi de 12,99 (95% IC 2,41 - 70,0) para grávidas com idade inferior a 20 anos e de 2,09 (95% IC 1,05 - 4,14), para grávidas com idade superior a 30 anos. Discussão e Conclusão: Na nossa amostra, a prevalência de anemia na primeira metade da gravidez foi inferior à reportada noutros estudos. No entanto, mais de 30% das grávidas apresentaram carência de ferro. A idade materna foi o único fator de risco identificado.
