Maternal drinking behavior and Fetal Alcohol Spectrum Disorders in adolescents with criminal behavior in southern Brazil.

Prenatal alcohol exposure can have serious and permanent adverse effects. The developing brain is the most vulnerable organ to the insults of prenatal alcohol exposure. A behavioral phenotype of prenatal alcohol exposure including conduct disorders is also described. This study on a sample of Brazilian adolescents convicted for criminal behavior aimed to evaluate possible clinical features of Fetal Alcohol Syndrome (FAS). These were compared to a control group of school adolescents, as well as tested for other environmental risk factors for antisocial behavior. A sample of 262 institutionalized male adolescents due to criminal behavior and 154 male students aged between 13 and 21 years comprised the study population. Maternal use of alcohol was admitted by 48.8% of the mothers of institutionalized adolescents and by 39.9% of the school students. In this sample of adolescents we could not identify individual cases with a clear diagnosis of FAS, but signs suggestive of FASD were more common in the institutionalized adolescents. Social factors like domestic and family violence were frequent in the risk group, this also being associated to maternal drinking during pregnancy. The inference is that in our sample, criminal behavior is more related to complex interactions between environmental and social issues including prenatal alcohol exposure.

Proteus syndrome associated with hemimegalencephaly and Ohtahara syndrome: report of two cases.

The authors report two cases of Brazilian children with most of the common syndromic features of Proteus syndrome, such as asymmetric overgrowth of tissues, skin abnormalities, hypotonia and mental retardation. In both patients, a refractory epilepsy, compatible with Ohtahara syndrome, as well as hemimegalencephaly, with asymmetric distribution of facial fat, were also diagnosed.

Down syndrome with congenital hydrocephalus: case report.

Down syndrome is the most frequent genetic cause of mental retardation. Although usually presenting dysmorphic features and organ malformations, it is rarely associated with congenital hydrocephalus. The case of a male neonate whose hydrocephalus was detected since the pregnancy and was discovered to have the syndrome at birth is reported. Chromosomal analysis confirmed the genetic disorder, and hydrocephalus was treated with ventriculoperitoneal shunt because of abnormal increase of head circumference. The patient has been accompanied and his development is considered normal when compared to the expected for those affected by the syndrome.

A síndrome de Down é a causa genética mais freqüente de retardo mental. Embora comumente apresentando dismorfias e malformações de órgãos, raramente está associada à hidrocefalia congênita. O caso de um recém-nascido masculino cuja hidrocefalia foi detectada desde a gravidez e que se descobriu ser portadora da síndrome ao nascimento é relatado. O cariótipo confirmou a anormalidade genética, e a hidrocefalia foi tratada com derivação ventriculoperitoneal devido ao aumento anormal do perímetro cefálico. O paciente está sendo acompanhado e seu desenvolvimento é considerado normal quando comparado ao esperado para os portadores da síndrome.
