Levonorgestrel Intrauterine Device Effectiveness in Heavy Menstrual Bleeding Treatment in Obese Women

Objective:We aimed to identify if there was any difference in Levonorgestrel-releasing intrauterine system (LNG-IUS) efficacy or weight gain when used in heavy menstrual bleeding (HMB) treatment, between obese and non-obese women. Population and methods: This was a case-controlled retrospective study undertaken between 2002-2007. 194 women with HMB were treated with LNG-IUS and stratified into two groups accordingly with body mass index (BMI): Obese Group – BMI ≥ 30 (n=53) and Non-obese Group – BMI < 30 (n=141). Age, weight, days of spotting and days of menses were analyzed at 1, 3 and 6 months after insertion and then annually until 2 years. Analytic parameters of anemia (hemoglobin, serum ferritin, mean corpuscular volume) were reviewed at pre-insertion, at 6 months and then annually until 2 years. Results: During the 2-year follow-up there was a similar improvement in two groups regarding duration of menses, spotting and in analytic parameters of anemia. A statistically significant improvement was observed in obese group after 2 years of treatment regarding analytic parameters of anemia and menstrual characteristics, without weight gain. Conclusion: In obese women, the LNG-IUS is an effective treatment for heavy menstrual bleeding, without being associated to weight gain.

Torção Anexial

Adnexal torsion is a rare event whose diagnosis requires a high degree of suspicion since its presentation is clinical and laboratory nonspecific. Ultrasound constitute the first-line exam in the imaging evaluation and timely surgical treatment, with detorsion, is mandatory to allow the preservation of the structures involved. The effectiveness of preventive measures of recurrence is yet to be determined. In this paper, in addition to a literature review, the authors present a new imaging finding and propose a flowchart for therapeutic decision.

Sépsis Materna

Infections during pregnancy are prevalent. A small number of cases, however, may be life-threatening. Sepsis may be associated with multiple organ dysfunction and high mortality and it is one of the most common causes of direct maternal death often associated with the inability to recognize the severity of the illness. Long-term morbidity associated with maternal sepsis is significant and includes chronic pelvic inflammatory disease, chronic pelvic pain, bilateral tubal occlusion and infertility. The impact on neonatal mortality is also substantial, with over one million infection-related neonatal deaths eve - ry year. In the last few years, a vast number of clinical reviews of severe sepsis in pregnancy have been published, focusing on the characteristics of pregnant woman, the establishment of a specific treatment and the relevance of pregnancy surveillance by a multidisciplinary team. The treatment of sepsis is time-critical and requires early diagnosis, aggressive resuscitation, antibiotic administration and source control.

Rotura Uterina em Mulheres com Cesariana Anterior em Prova de Trabalho de Parto

Uterine rupture during a trial of labor after previous cesarean (TOLAC) delivery is a rare, but serious complication. Several factors can increase the risk of uterine rupture, so the assessment of individual risks with adequate counseling is ne - cessary. The initial signs and symptoms are usually nonspecific, hampering timely diagnosis and prompt delivery of the fetus, necessary for optimal outcome. The purpose of this document is to review the risks factors for uterine rupture during TOLAC, as well as the current clinical value of the classically described premonitory signs and symptoms.

Gastroenterite Aguda por Rotavírus em Portugal: Estudo Multicêntrico

Os dados sobre diarreia por rotavírus em Portugal são limitados. Este estudo teve como objectivo estimar a proporção de gastroenterite aguda por este vírus em crianças observadas em serviços de urgência de vários hospitais do país e analisar as suas características clínicas e moleculares. Estudo prospectivo, multicêntrico, observacional, incluindo crianças como menos de 5 anos, com gastroenterite aguda, observadas em 10 serviços de urgência pediátricos, entre outubro de 2008 e setembro de 2009. Foram recolhidos dados demográfico e clínicos. as amostras positivas de rotavírus foram genotipadas por reacção em cadeia da polimerase. Foram incluídas 1846 crianças, 58% do sexo masculino, com idade média de 19,3 +- 14,4 meses. Foi identificado rotavírus nas fezes em 28,3% (intervalo de confiança 95%, 26,2-30,4%), com maior proporção no inverno e na primavera e em crianças com idade de 7-24 meses. Os genótipos mais frequentes foram G4P(8) (46%) e G1P(8) (37%), com variações de norte para sul. As crianças com gastroenterite por rotavírus tinham probabilidade significativamente superior (p<0,001) de ter febre, vómitos, perda de peso, desidratação e necessidade de internamento, comparativamente aos casos negativos para rotavírus. A gastroenterite aguda por rotavírus em crianças portuguesas com idade inferior a 5 anos associou-se a maior morbilidade e hospitalização do que nos casos sem identificação de rotavírus. Houve diferenças importantes na distribuição dos genótipos entre as regiões. Na era das vacinas contra o rotavírus, este conhecimento é importante para as decisões relativas à prevenção da doença e para monitorizar tendências da epidemiologia molecular do rotavírus.

Congenital Complete Atrioventricular Block. Case Report and Review of the Literature

Introduction: Congenital complete atrioventricular block (AVB) without cardiac malformation is a rare and potentially fatal condition. In most cases it is associated with maternal systemic lupus erythematosus through transplacental passage of antibodies anti-SSA/Ro and/or anti-SSB/La. Antenatal fluorinated-steroids have been successful in reversing first and second degree congenital AVB but inconsistent in third degree block. Case Report:The authors report a case of fetal bradycardia diagnosed at 24 weeks of gestation. The fetal echocardiogram revealed a second/third degree AVB without structural heart disease. Maternal anti-SSA/Ro antibodies were detected. There was no blockage improvement with maternal oral fluorinated-steroids. An elective cesarean section was performed at term with the delivery of a healthy girl that required an epicardical pacemaker on the 8th day of life. Conclusion: In this case, treatment with maternal fluorinated corticosteroids was not effective in preventing progression of the heart block.

Predição de Pré-Eclâmpsia no Primeiro Trimestre em Gravidezes de Baixo Risco: Determinação do Cut-Off numa Amostra da População Portuguesa

Objective:We aimed to identify the cut-off for risk of pre-eclampsia (PE) in Portuguese population by applying the first trimester prediction model from Fetal Medicine Foundation (FMF) in a prospective enrolled cohort of low risk pregnant women. Population and methods: A prospective cohort of low risk singleton pregnancies underwent routine first-trimester scree - ning from 2011 through 2013. Maternal characteristics, blood pressure, uterine artery Doppler, levels of pregnancy-associated plasma protein-A (PAPP-A) and free b-human chorionic gonadotropin were evaluated. The prediction of PE in first trimester was calculated through software Astraia, the outcome obtained from medical records and the cutoff value was subse quently calculated. Results:Of the 273 enrolled patients, 7 (2.6%) developed PE. In first trimester women who developed PE presented higher uterine arteries resistance, represented by higher values of lowest and mean uterine pulsatility index, p <0.005. There was no statistical significance among the remaining maternal characteristics, body mass index, blood pressure and PAPP-A. Using the FMF first trimester PE algorithm, an ideal cut-off of 0.045 (1/22) would correctly detect 71% women who developed PE for a 12% false positive rate and a likelihood ratio of 12.98 (area under the curve: 0.69; confidence interval 95%: 0.39-0.99). By applying the reported cutoff to our cohort, we would obtain 71.4% true positives, 88.3% true negatives, 11.4% false positives and 28.6% false negatives. Conclusion: By applying a first trimester PE prediction model to low risk pregnancies derived from a Portuguese population, a significant proportion of patients would have been predicted as high risk. New larger studies are required to confirm the present findings.

Miocardiopatia Periparto. Paragem Cardiorespiratória Pós-Parto Complicada por Acretismo Placentar

Peripartum cardiomiopathy is a rare and life-threatening cardiac disease that affects young women previously healthy, during the peripartum period. It is a form of dilated cardiomyopathy with left-sided systolic dysfunction, which may lead to symptoms and signs of congestive heart failure. The exclusion diagnosis is based essentially on clinical presentation and initial symptoms may mimic physiologic alterations of pregnancy. The authors present a case of a 34 week multiple gestation with a growth restriction of one of the fetus and with a suspicion of a mild pre-eclampsia, motive by which we decided labour induction. During placental expulsion, in which we noticed difficulty in finding placental cleavage, the patient presented an assistoly, recovering after cardiorespiratory reanimation. However, the profuse bleeding after labour leaded to a life saving hysterectomy. Histological examination revealed placenta accreta. The echocardiography performed post-operatively diagnosed a dilated cardiomyopathy.

Fibromioma Extra-Peritoneal do Ligamento Redondo. Caso Clínico

Fibromyoma of the round ligament should be considered as a possible etiology for a large preperitoneal tumor. We report a case of a 44-year-old female who was found to have a fibroleiomyoma that measured 14 cm, weighed 3599 gr and had grown in the abdominal wall between the muscle and the peritoneum, taking as its starting point the right round ligament.
