PURPOSE: To evaluate the association between central nervous system (CNS) malformations and the C677T-MTHFR mutation in fetal blood. METHODS: A case-control study was conducted to compare the MTHFR-C677T mutation detected in 78 fetuses with CNS malformations and with 100 morphologically normal fetuses. Genomic DNA was extracted and purified from fetal blood using the Wizard® Genomic DNA Purification Kit (Promega Corp., Madison, WI, USA) according to manufacturer's protocol. The polymerase chain reaction (PCR) was used to assay the thermolabile MTHFR-C677T mutation. The γ² and the Fisher's exact tests were used for descriptive analysis and the Wilcoxon test was used for univariate analysis. Logistic regression analysis was performed to identify which variables were predictors of CNS malformation. RESULTS: Cases and controls were similar regarding maternal characteristics such as age and number of deliveries and abortions. The MTHFR-C677T mutation was detected in 20 cases (25.6%) and in 6 controls in its heterozygous form (OR 10.3; 95%CI 3.3-32.2) and in 6 cases (7.7%) and in 1 control in its homozygous form (OR 12.3; 95%CI 1.3-111.1), and the differences were statistically significant. CONCLUSION: The presence of the MTHFR-C677T mutation in fetal blood was consistent with a higher risk of CNS malformations, both in the heterozygous and homozygous forms.

PURPOSE: To analyze and compare the knowledge and opinions of Law and Medical students regarding the issue of abortion in Brazil. METHODS: This was a cross-sectional study involving 125 graduate students from the class of 2010. Of these, 52 were medical students (MED group) and 73 law students (LAW group). A questionnaire was applied based on published research about the topic. Dependent variables were: monitoring the abortion debate, knowledge concerning situations where abortion is permitted under Brazilian law, opinion about situations that agree with extending legal permission to terminate pregnancy and prior knowledge of someone who has undergone induced abortion. Independent variables were: sex, age, household income and graduation course. Statistical analysis: χ² and Fisher's exact tests, with the level of significance set at 5%. RESULTS: Most interviewees reported monitoring the debate on abortion in Brazil (67.3% of the MED group and 70.2% of the LAW group, p>0.05). When assessing knowledge on the subject, medical students had a significantly higher percentage of correct answers than law students (100.0 and 87.5%, respectively; p=0.005) regarding the legality of abortion for pregnancies resulting from rape. Elevated percentages of correct responses were also recorded for both groups in relation to pregnancies that threaten the life of the mother (94.2 and 87.5% for MED and LAW groups, respectively), but without statistical significance. A significant percentage of respondents declared they were in favor of extending legal abortion to other situations, primarily in cases of anencephaly (68%), pregnancy severely harming the mother's physical health (42.1%) or that of the fetus in cases of severe congenital malformation (33.7%). CONCLUSION: Results showed a satisfactory knowledge on the part of law and medical school graduate students regarding the legality of abortion in Brazil, combined with a favorable trend towards extending legal permission to other situations not covered by the law. It is important to underscore the inclusion of this topic in the undergraduate curriculum and the development of inter-professional teaching strategies.

PURPOSE: to describe to emotional process experienced with termination of pregnancy after the diagnosis of lethal fetal malformation. METHODS: thirty-five pregnant women who underwent termination of pregnancy for lethal fetal anomaly after judicial permission were interviewed. The most frequent fetal malformation was anencephaly (71.5%). The patients were submitted to an open interview as soon as the diagnosis of fetal malformation was confirmed, allowing them to express their feelings and stimulating them to think about asking for termination of pregnancy. The mean time spent until the judicial agreement was 16.6 days. The women who requested and were submitted to the procedure of abortion were invited to return for psychological evaluation after 30-60 days. At this moment, a semi-structured interview was performed to find the emotional aspects and feelings that existed. RESULTS: thirty-five patients were interviewed. The decision-making feelings about termination of pregnancy were negative for 60%, 51.4% declared that they had no doubts about the assumed decision and 65.7% declared that their own opinion was more important for decision than anyone else's. Most of the women (89%) affirmed to remember the facts about the procedure that they experienced, 91% affirmed that they would have the same attitude in the case of another similar situation in the future and 60% declared that they would advise someone to opt for termination of pregnancy if asked about the same situation. CONCLUSIONS: the anguish experienced showed that the process of thinking is very important for the decision-making process and posterior satisfaction with the assumed posture. The psychological follow-up allows to review the moral and cultural values in order to help the decision-making process with the aim of minimizing the suffering.
