CONTEXT: Interstitial pregnancy is a rare form of ectopic pregnancy for which the best therapeutic course of action has yet to be determined. Surgical intervention entails a high risk of hemorrhage due to the great vascularization of the cornual region of the uterus. Case descriptions facilitate the analysis of results and aid clinicians in determining the most appropriate course of action in these situations. CASE REPORT: In a patient with an ultrasound diagnosis of interstitial pregnancy, clinical treatment using methotrexate was chosen. However, after one week, there was a marked decline in the serum level of the β subunit of chorionic gonadotropin hormone, although an ultrasound examination revealed embryonic cardiac activity. A second dose of the chemotherapy was administered. Embryonic cardiac activity persisted 48 hours later. Video laparoscopy was performed to achieve right-side cornual resection, which resulted in satisfactory resolution of the case.resUMo CONTEXTO: A gestação intersticial é uma forma rara de gestação ectópica. A melhor opção terapêu-tica ainda não está definida, havendo risco de hemorragia com o tratamento cirúrgico, em decorrên-cia da grande vascularização na região cornual uterina. A descrição de casos facilitam a análise dos resultados e ajuda os clínicos a determinarem a melhor conduta nessas situações. RELATO DE CASO: Em paciente com diagnóstico ultrassonográfico de gestação intersticial, optou-se por tratamento clínico com administração de metotrexate. Após uma semana, houve declínio acentuado do nível sérico da sub-unidade β do hormônio gonadotrófico coriônico, porém, na ultrassonografia, foi detectada a presença de atividade cardíaca embrionária. Foi administrada uma segunda dose do quimioterápico. Após 48 horas, a atividade cardíaca persistia. Realizou-se vídeo-laparoscopia para ressecção cornual direita, com resolução satisfatória do caso.I MD, MSc. Volunteer at Birth Control Outpatient

Objective: To evaluate the prevalence of group B Streptococci in pregnant women of a corporate health program, as well as the epidemiological correlations. Methods: This retrospective study used medical records of patients who participated of the prenatal care program at a private hospital in the city of São Paulo (SP), Brazil, from 2015 to 2016. Those who abandoned the program or had incomplete data in their medical records were excluded. Quantitative variables were described by means, standard deviations, median, minimal and maximal values. Parity and socioeconomic status were described by absolute frequency and percentages. We used logistic regression models in the software (SPSS) to analyze correlations of variables according to vaginal-rectal culture, considering a 95%CI and p-values. Variables were age, number of pregnancies, weight gain in pregnancy and gestational age at delivery. Results: A total of 347 medical records were included, and after applying the exclusion criteria, 287 medical records composed the final sample. Patients' age ranged between 17 and 44 years. Mean age was 30.6 years, 67 patients had positive result for group B Streptococcus (prevalence of 23.3%; 95%CI: 18.7-28.5). Conclusion: Considering the high prevalence of group B Streptococcus in our service, the antibiotic prophylaxis strategy based on rectovaginal culture screening approach seems to be cost-effective.
