Congenital toxoplasmosis in a reference center of Paraná, Southern Brazil

This study describes the characteristics of 31 children with congenital toxoplasmosis children admitted to the University Hospital of Londrina, Southern Brazil, from 2000 to 2010. In total, 23 (85.2%) of the mothers received prenatal care but only four (13.0%) were treated for toxoplasmosis. Birth weight was <2500 g in 37.9% of the infants. During the first month of life, physical examination was normal in 34.5%, and for those with clinical signs and symptoms, the main manifestations were hepatomegaly and/or splenomegaly (62.1%), jaundice (13.8%), and microcephaly (6.9%). During ophthalmic examination, 74.2% of the children exhibited injuries, 58.1% chorioretinitis, 32.3% strabismus, 19.4% microphthalmia, and 16.2% vitreitis. Anti-Toxoplasma gondii IgM antibodies were detected in 48.3% of the children. Imaging brain evaluation was normal in 44.8%; brain calcifications, hydrocephaly, or both conditions were observed in 27.6%, 10.3%, and 17.2%, respectively, of the patients. Patients with cerebrospinal fluid protein > 200 mg/dL presented more brain calcifications (p = 0.0325). Other sequelae were visual impairment (55.2% of the cases), developmental delay (31.0%), motor deficit (13.8%), convulsion (27.5%), and attention deficit (10.3%). All patients were treated with sulfadiazine, pyrimethamine, and folinic acid, and 55.2% of them exhibited adverse effects. The results demonstrate the significance of the early diagnosis and treatment of toxoplasmosis during pregnancy to reduce congenital toxoplasmosis and its consequences.

Programas de controle da toxoplasmose congênita / Programs for control of congenital toxoplasmosis

A toxoplasmose congênita pode causar aborto e danos neurológicos e/ou oculares ao feto. Desde que a Áustria e a França estabeleceram a triagem pré-natal, a prevalência da toxoplasmose caiu de 50 por cento para 35 por cento e de 84 por cento para 44 por cento, respectivamente. Outros países, como o Reino Unido, adotam práticas educativas para reduzir o risco de infecção em gestantes soronegativas. No Brasil, a triagem pré-natal é realizada nos estados do Mato Grosso do Sul e Minas Gerais e nas cidades de Curitiba e Porto Alegre. Em Londrina, Paraná, foi implantado o "Programa de Vigilância da Toxoplasmose Adquirida na Gestação e Congênita", que se baseia na triagem sorológica, com orientação sobre as medidas de prevenção e monitoramento sorológico trimestral nas gestantes inicialmente soronegativas, além do acompanhamento das gestantes e crianças com infecção aguda e notificação dos casos. Nos primeiros quatro anos da implantação, a avaliação do programa demonstrou uma redução de 63 por cento no número de gestantes e de 42 por cento no número de crianças encaminhadas aos serviços de referência, resultando na liberação de vagas para o atendimento de pacientes com outras doenças. Quanto aos medicamentos, houve redução de 62 por cento no consumo de ácido folínico e de 67 por cento de sulfadiazina. Além disso, a definição dos protocolos resultou na padronização do atendimento e segurança para a tomada de decisões por parte dos médicos. Portanto, como existem diversos protocolos individualizados nos diversos serviços e regiões, o estabelecimento de uma conduta ideal e consensual, com respaldo técnico, implicará na adoção de medidas que, certamente, ocasionarão economia aos cofres públicos, com a diminuição da toxoplasmose congênita.

Congenital toxoplasmosis can cause miscarriage and neurological and/or eye damage to the fetus. Since Austria and France established the prenatal screening, the prevalence of toxoplasmosis has declined from 50 percent to 35 percent and 84 percent to 44 percent, respectively. Other countries, such as the United Kingdom, have educational practices to reduce the risk of infection in seronegative pregnant women. In Brazil, prenatal screening is carried out in the states of Mato Grosso do Sul and Minas Gerais and the cities of Curitiba and Porto Alegre. In Londrina, state of Parana, the "Health Surveillance Program for Toxoplasmosis Acquired during Pregnancy and Congenital Toxoplasmosis" was established, which is based on serological screening, advising on prevention measures and quarterly serological monitoring in pregnant women that are initially seronegative, in addition to the monitoring of pregnant women and children with acute infection and case notification. In the first four years of implementation, the program evaluation showed a 63 percent reduction in the number of pregnant women and 42 percent in the number of children referred to reference services, resulting in the opening of vacancies for the care of patients with other diseases. As for medications, there was a 62 percent reduction in consumption of folic acid and 67 percent of sulfadiazine. Moreover, the definition of the protocols resulted in the standardization of care and safety for the decision-making by physicians. Therefore, as there are several protocols individualized in various departments and regions, the establishment of an ideal, consensual conduct with technical support, will result in implementing measures that will certainly save public resources, with the decrease in congenital toxoplasmosis.

Rotura hepática na gravidez - Relato de caso / Hepatic rupture in pregnancy - A case report

Rotura hepática é uma das mais sérias e catastróficas complicaçöes da gravidez, sua incidência varia de 1:45000 a 1:225000 partos. É usualmente associada a pré-eclâmpsia. A mortalidade materna é de cerca de 60 a 86 por cento e a fetal pode atingir de 56 a 75 por cento. O diagnóstico é difícil, mas freqüentemente confirma-se pela presença de sangramento maciço e choque hipovolêmico. Relatamos o caso de uma paciente na 32ª semana de gravidez complicada por hemorragia hepática espontânea associada a pré-eclâmpsia, que foi submetida a tratamento cirúrgico com bom resultado.
