RESUMO
As infecções no trato urinário (ITUs) representam a forma mais comum de infecções bacterianas em gestantes. A gravidez é uma situação que predispõe ao aparecimento das ITUs, devido às mudanças fisiológicas (mecânicas e hormonais) que ocorrem nesse período da vida da mulher, facilitando à transformação das mulheres bacteriúricas assintomáticas (BA) em sintomáticas. A BA acomete entre 2-10% das gestantes, se não tratadas adequadamente podem desenvolver pielonefrite em 40% dos casos. As ITUs manifestam-se clinicamente por disúria, polaciúria, urgência miccional e dor no baixo ventre na cistite, arrepios de frio e lombalgia na pielonefrite, ou completa ausência de sintomas na bacteriúria assintomática. O diagnóstico, na maioria das vezes, com exceção da bacteriúria assintomática, é clínico. Deve-se levar em consideração fatores, como a condição da paciente, a tolerabilidade e a toxicidade materna e fetal para a escolha da melhor abordagem terapêutica. O objetivo do presente estudo foi revisar os trabalhos que abordassem fisiopatologia, formas clínicas das ITUs, epidemiologia, etiologia, métodos de diagnóstico e tratamento das infecções urinárias na gestação.
The urinary tract infections (UTIs) represent the most common form of bacterial infections in pregnant women. Pregnancy is a situation that predisposes to the development of UTIs due to physiological changes (mechanical and hormonal) that occur in this period of women?s life, facilitating the transformation of asymptomatic bacteriuria women (AB) in symptomatic ones. AB affects 2-10% of pregnant women, and if not properly treated, it can develop pyelonephritis in 40% of cases. UTIs are clinically manifested by dysuria, urinary frequency, urinary urgency and lower abdominal pain in cystitis, chills and low back pain in pyelonephritis, or complete absence of symptoms in asymptomatic bacteriuria. The diagnosis in most cases is clinical, except for asymptomatic bacteriuria. One should take into account factors such as the patient?s condition, tolerability, and maternal and fetal toxicity when choosing the best therapeutic approach. The aim of this study was to review the work that addressed pathophysiology, clinical forms of UTIs, epidemiology, etiology, diagnostic methods and treatment of urinary infections in pregnancy.
RESUMO
OBJECTIVE: To study the epidemiologic characteristics and underlying conditions that place pregnant women infected with H1N1 virus at increased risk for being admitted to the intensive care unit (ICU). METHODS: In this cross-sectional study conducted in Porto Alegre, Brazil, with 57 pregnant women hospitalized with the H1N1 influenza during the 2009 pandemic, we collected epidemiologic characteristics and assessed the rates of ICU admission according to pregnancy duration and the presence or absence of comorbidities. RESULTS: The median (range) of maternal age was 26 years (15-41 years), the pregnancy duration at the time of infection was 29 weeks (8-41 weeks), and the birth weight was 3180 g (740-3900 g). Five patients (8.8%) were in the first, 22 (38.6%) in the second, and 30 (52.6%) in the third trimester, and (22.8%) had comorbidities. Antiviral drugs were administered to all, and 46 (80.7%) patients received an early treatment. There were no maternal, fetal, or neonatal deaths. Eight patients (14%) required ICU admission and 15 (50%) of the patients who gave birth during their hospitalization underwent a cesarean delivery. The risk of being treated at the ICU did not increase for patients with comorbidities (P=0.22) or an advanced pregnancy (P=0.31). The study revealed a relationship between early initiation of an antiviral treatment and a lower mortality rate. CONCLUSION: Neither an advanced pregnancy nor comorbidities increased the risk of being admitted to the ICU but, compared with the results of other studies, a prompt treatment lowered mortality.

The authors present a rare case of hepatic fascioliasis in a female patient 53-years-old, coming from the rural zone of Rio Grande do Sul, a southern State from Brazil. She has presented with biliary colic, fluctuant jaundice and eosinophilia. Abdominal ultrasound has shown a dilated biliary tree with inside heterogeneous images. At surgery we have found inside the biliary tree several Fasciola hepatica, which have been pulled out with the choledocoscope. We have proceeded with biliodigestive anastomosis using the small intestine. The patient remains asymptomatic six months after surgical procedure. Small intestine. The patient remains asymptomatic six months after surgical procedure.
