Objetivo: Descrever o perfil sóciodemográfico, exposição à teratógenos e anormalidades oculares congênitas em pacientes brasileiros portadores da sequência de Möbius Método: Quarenta e quatro pacientes recrutados da Sociedade Brasileira de Sequência de Möbius foram examinados. Este estudo transversal incluiu 41 pacientes que preencheram os critérios de inclusão do estudo (média das idades: 9,0 ± 5,5 anos). Mãe/responsável dos pacientes responderam a um questionário sobre perfil sóciodemográfico e história gestacional. Foi realizado exame oftalmológico de todos os pacientes. Eles foram agrupados em dois grupos de acordo com a exposição ao misoprostol durante a gestação e seus dados foram comparados. Resultados: Mães/responsáveis referiram gravidez indesejada em 36 (88%) dos casos. Destas, 19 (53%) fizeram uso de misoprostol no primeiro trimestre de gestação. Houve uma tendência do grupo de mães não expostas ao misoprostol de terem um estado civil estável (P=0,051). Duas (11%) mães do grupo de expostas ao misoprostol relataram primeiro grau incompleto e três (14%) do grupo de não expostas (P=0,538). A exposição das mães à cocaína, maconha, álcool e cigarro foi similar em ambos os grupos (P=0,297, P=0,297, P=0,428, P=0,444, respectivamente). Houve um caso (5%) de Rubéola no grupo de mães não expostas. As principais malformações associadas nos pacientes expostos e não expostos foram, respectivamente: estrabismo (72% e 77%), e diminuição da lágrima emocional (47% e 36%) e lagoftalmia (32% and 41%). Conclusão: Estado civil estável foi mais frequente em mães que não fizeram uso de misoprostol durante a gestação. Exposição à outros teratógenos e malformações oculares tiveram distribuição semelhante em ambos os grupos.

Purpose: To assess the sociodemographic profiles, teratogen exposures, and ocular congenital abnormalities in Brazilian patients with Möbius sequence. Method: Forty-four patients were recruited from the Brazilian Möbius Sequence Society. This cross-section comprised 41 patients (age, mean ± standard deviation, 9.0 ± 5.5 years) who fulfilled the inclusion criteria. The parent or caregiver answered a questionnaire regarding sociodemographic data and pregnancy history. Patients underwent ophthalmological assessments. They were subdivided into groups according to misoprostol exposure during pregnancy, and the two groups were compared. Results: Mothers/caregivers reported unplanned pregnancies in 36 (88%) cases. Of these, 19 (53%) used misoprostol during their first trimesters. A stable marital status tended to be more frequent in the unexposed group (P=0.051). Incomplete elementary school education was reported by two (11%) mothers in the exposed group and by three (14%) mothers in the unexposed group (P=0.538). The mothers' gestational exposures to cocaine, marijuana, alcohol, and cigarettes were similar in both groups (P=0.297, P=0.297, P=0.428, and P=0.444, respectively). One (5%) case of Rubella infection during pregnancy was found in the unexposed group. The main malformations in the exposed and unexposed groups were the following: strabismus (72% and 77%, respectively), lack of emotional tearing (47% and 36%, respectively), and lagophthalmos (32% and 41%, respectively). Conclusion: Stable marital statuses tended to be more frequent among mothers that did not take misoprostol during pregnancy. Exposures to other teratogens and the main ocular abnormalities were similar in both groups.

OBJECTIVE: To research technical alternatives for permanent gastrostomy that minimizes the drawbacks and complications reported by several authors. MATERIALS AND METHODS: An experimental model was developed where the material was divided into 2 groups: the study group (SG) composed of 12 half-breed dogs where the proposed technique was applied, and the control group (CG) composed of 10 animals where a gastrostomy as proposed by Webster in 1974 was applied. On the 90th postoperative day, both groups underwent tests for assessing competence concerning leakage. These were performed under general anesthesia and following sacrifice. RESULTS: In the SG, under anesthesia only one animal had leakage through the gastrostomy. Following sacrifice, leakage was observed in 2 animals. In the CG, under anesthesia, 2 animals had leakage and, following sacrifice, only 1 animal did not present leakage. On histopathological analysis of the SG, gastric mucosa was evidenced around the jejunal tubes, with normal features, moderate inflammatory mononuclear infiltrate in jejunal tubes and only slight infiltrate around the gastrostomy stoma. In the CG, ulceration was constant around the external stoma of the gastrostomy tubes. In the corium, the inflammatory infiltrate was less intense than in the SG. The SG proved to be more efficacious than the CG concerning leakage, and this efficacy is attributed to the submucous valvular system. CONCLUSION: The featured technique showed competence concerning leakage, allowing its clinical applicability as an alternative for permanent gastrostomy.

Investigamos em portadores de esquistossomose hepatoesplênica após esplenectomia com ou sem auto-implante esplênico: índice de aderência, produção de superóxido (SP) e de TNF-alfa em monócitos, tratados ou não com tuftsina. Avaliamos três grupos: voluntários sadios CG (grupo controle) (n=12); esplenectomizados com auto-implante AG (n=18) e esplenectomizados sem auto-implante WAG (n=9). Índice de aderência e TNF-alfa não diferiram entre os grupos. SP foi semelhante em CG e AG na 1ª hora após estimulação celular. SP foi maior em todos intervalos de tempo nos grupos CG e AG, comparados ao WAG. O tratamento com tuftsina recuperou o padrão de normalidade de SP em AG, com aumento da 1ª para a 2ª hora nos níveis do CG. O tratamento com tuftsina não alterou SP em WAG, permanecendo reduzida em todos intervalos. O auto-implante esplênico parece recuperar e manter os parâmetros imunológicos avaliados, que têm participação importante na resposta do hospedeiro às infecções.

Adherence index, superoxide and TNF-alpha production in monocytes, with or without tuftsin treatment, were investigated in hepatosplenic schistosomiasis mansoni bearers with splenectomy with or without autologous implantation of spleen tissue. Three groups were evaluated: Healthy volunteers control group (CG) (n=12); Splenectomy with seft auto-transplant AG (n=18) and Splenectomy without auto-transplant WAG (n=9). Adherence index and TNF-alpha did not differ among the groups. Superoxide production was similar in CG and AG, in the 1st hour after cell stimulation. SP was larger in each hour time in CG and AG groups as compared WAS group. TT recovered normal pattern of SP in AG comparable with levels found in CG, with increase from the 1st to 2nd hour. However, TT did not alter SP in WAG, which remained reduced in all time points. Autologous implantation of spleen tissue seems to contribute for recovery and maintenance of the evaluated immunological reactions, which might be important in response to infections.
