The aim of this study was to evaluate associations between seropositivity for IgG and IgM anti-Toxoplasma gondii antibodies and socio-economic and environmental variables in pregnant women of Londrina, state of Paraná, Brazil. We interviewed 492 pregnant women, each of whom answered an epidemiological questionnaire, and collected blood samples for measurement of IgG and IgM anti-T. gondii antibodies by chemiluminescence. A confirmatory diagnosis of acute infection was made by an IgG avidity test. Titres of specific IgG anti-T. gondii were obtained by IFAT. Seropositivity for IgG anti-T. gondii antibodies was observed in 242 women (49.2%) and, of these, six pregnant women (1.2%) showed seropositivity for IgM. Age group, level of education, per capita income, presence of a cat in the house and a habit of eating green vegetables were all factors associated with a greater chance of infection with T. gondii. This study showed that 250 (50.8%) pregnant women were susceptible to T. gondii and considered to be at high risk for toxoplasmosis during pregnancy. Based on the results obtained, is critical to establish a program of health surveillance for toxoplasmosis, in order to contribute to diagnosis and early treatment during the prenatal period. It is also necessary to introduce measures to prevent the Toxoplasma infection in seronegative pregnant women.

Penetrating cardiac trauma carries high mortality rates. It has been commonly associated with stabbing, but increasing urban violence has led to growing numbers of gunshot heart wounds. The latter have higher mortality rates among penetrating cardiac injuries and may affect multiple heart chambers, with even higher mortality rates. We report a patient, victim of an attempted armed robbery, who had a transfixing gunshot wound to the heart, successfully operated at our institution.Descriptors: Heart injuries. Wounds, gunshot. Heart ventricles. ResumoO trauma cardíaco penetrante apresenta altas taxas de mortalidade. É comumente associado a lesões por armas brancas, porém crescentes índices na violência urbana têm contribuído para o aumento no número de ferimentos cardíacos por projéteis de armas de fogo. Estas possuem as maiores taxas de mortalidade dentre os ferimentos cardíacos penetrantes e podem acometer múltiplas câmaras cardíacas, com índices de mortalidade ainda mais elevados. Apresentamos um caso de um paciente, vítima de tentativa de roubo, que sofreu ferimento cardíaco transfixante por projétil de arma de fogo, operado com sucesso em nossa instituição.Descritores: Traumatismos cardíacos.

Objective To describe a new technique of sternal closure, modified from the conventional figure-of-eight approach, which can provide a secure closure and prevent sternal complications. Methods The modified technique is based on the intercalation of the caudal portion of each steel wire passed along the sternum. This is a retrospective analysis of patients operated with this modified technique at our institution between January 2014 and December 2016. Results One hundred and forty-three patients underwent sternal closure with the modified technique. In-hospital mortality rate was 1.4% (n=2). No sternal instability was observed at 30 days postoperatively. Two patients developed mediastinitis that required extraction of the wires. Conclusion Short-term results have shown that the modified sternal closure technique can be used safely and effectively, with complications rates being consistent with worldwide experience.

A 76-year-old man with situs inversus totalis underwent a successful off-pump three-vessel coronary artery bypass surgery. The postoperative course was uneventful, and the patient was discharged 8 days later. At 9-month follow-up a coronary computed tomography angiography confirmed the viability of all of the grafts, and one year after the operation the patient remained asymptomatic. It comprises the fifth Brazilian case of a coronary surgery in a patient with situs inversus totalis and the first one of the country of a coronary artery bypass surgery without the use of the cardiopulmonary bypass in this condition.

A 23-year-old man suffered a penetrating injury caused by a metallic fragment thrown from a grass-cutting tool, resulting in perforating injuries in the stomach, diaphragm, heart, and lungs.
