Pregnancy and puerperium are periods of blood hypercoagulability and, therefore, of risk for thromboembolic events. Renal vein thrombosis is a serious and infrequent condition of difficult diagnosis. This study reported a case of renal vein thrombosis in the puerperium, and described the clinical case, risk factors, diagnostic methods, and treatment instituted.

To evaluate the factors associated with anemia among pregnant women receiving public health care in a capital city in Northeastern Brazil.
This was a cross-sectional study conducted on a sample of 428 patients obtained on the basis of the estimated prevalence of anemia during pregnancy (50%), a 95% confidence interval (95%CI), an error of 5% and a sample loss of 20%. Pregnant women who lived in the city and were served by the municipal public health network were considered to be eligible for the study. Socioeconomic, lifestyle, clinical and anthropometric data and dietary iron intake were obtained, and capillary hemoglobin was determined. Anemia was identified as a hemoglobin level <11 g/dL, and its association with risk factors was tested using multivariate Poisson regression analysis, with the results expressed as the Prevalence Ratio (PR) and 95%CI.
The prevalence of anemia was 28.3% and was higher among women with more members in the household (PR=1.49; 95%CI 1.01-2.22; p=0.046) and those living with food insecurity (PR=1.43; 95%CI 1.00-2.04; p=0.047).
The prevalence of anemia among pregnant women receiving care from the public health system of the city is a moderate public health problem, requiring the planning of effective measures for its control.

PURPOSE: to determine the prevalence and risk factors associated to anemia in pregnant women from the semiarid region of Alagoas, Brazil. METHODS: transversal study comprising a sample (n=150) obtained taking into consideration the prevalence estimated by World Health Organization of 52%, an error of 8% and a confidence interval of 95%. Sampling has been done in three stages: 15 towns among the 38 in the region, four census sectors by town and 24 residences by sector. All the resident pregnant women were eligible, and their socio-economic, demographic, anthropometric and health data have been collected. Anemia was identified at the <11 g/dL hemoglobin level (Hemocue®), and its association with risk factors, tested by multiple linear regression analysis. RESULTS: anemia prevalence was 50%. Seventy eight per cent of the pregnant women were under pre-natal care. From those, 79.3% were in the second or third trimester of gestation. Nevertheless, only 21.2% of them were taking iron supplementation. Variables (p<0.05) independently associated with anemia (anemic versus not-anemic pregnant women) were: larger number of family members (4.5±2.3 versus 4,3±2.3; p=0.02), lower age group of the pregnant woman (23.9±6.3 versus 24.7±6.7; p=0.04), or of her partner (34.5±15.8 versus 36±17.5; p=0.03), no toilet in the house (30.7 versus 24%; p<0.001), history of child abortion and/or death (32.4 versus 16.4%; p<0.001), living in the country (60 versus 46.7%; p=0.03), average per capita income

PURPOSE: to verify the association of abortion, recurrent fetal loss, miscarriage and severe pre-eclampsia with the presence of hereditary thrombophilias and antiphospholipid antibodies in pregnant women. METHODS: observational and transverse study of 48 pregnant women with past medical record of miscarriage, repeated abortion and fetal loss story (AB Group) and severe pre-eclampsia (PE Group), attended to in the High Risk Pregnancy Ambulatory of the Faculdade de Medicina (Famed) from the Universidade Federal de Mato Grosso do Sul (UFMS) from November 2006 to July 2007. The pregnant women of both groups were screened for the presence of antiphospholipid antibodies (anticardiolipin IgG and IgM, lupic anticoagulant and anti-beta2-glycoprotein I) and hereditary thrombophilias (protein C and S deficiency, antithrombin deficiency, hyperhomocysteinemia and factor V Leiden mutation). The laboratorial screening was performed during the pregnancy. The parametric data (maternal age and parity) were analyzed with Student’s tau test. The non-parametric data (presence/absence of hereditary thrombophilias and antiphospholipid antibodies, presence/absence of pre-eclampsia, fetal loss, miscarriage and repeated abortion) were analyzed with Fisher’s exact test in contingency tables. It was considered significant the association with p value <0.05. RESULTS: out of the 48 pregnant women, 31 (65%) were included in AB Group and 17 (35%) in PE Group. There was no significant difference between maternal age and parity within the groups. There was significant statistical association between recurrent fetal loss, recurrent abortions and previous miscarriages and maternal hereditary thrombophilias (p<0.05). There was no statistical association between the AB Group and the presence of antiphospholipid antibodies. Neither there were associations of the PE Group with maternal hereditary thrombophilias and the presence of antiphospholipid antibodies. CONCLUSIONS: the data obtained suggest routine laboratorial investigation for hereditary thrombophilias in pregnant women with previous obstetrical story of recurrent fetal loss, repeated abortion and miscarriage.
