Pilosidade Púbica na Criança e Hiperplasia Congénita Supra-Renal Não Clássica

Antes dos 8 anos de idade no sexo feminino e dos 9 no masculino, o aparecimento de pelos púbicos, pode ser a primeira manifestação de doença das gónadas ou das supra-renais. Para reconhecimento da Hiperplasia congénita supra-renal de início tardio, em situações de Pubarca prematura, realizámos a Prova curta de estimulação da supra-renal com Synacthen, em trinta crianças. Cinco meninas e um rapaz revelaram um défice de 21-hidroxilase, demonstrado pelo valores da 17-OH Progesterona sérica aos 60 minutos;28,8 +_ 15,2ng/ml, sendo num grupo de controle 2,30 ng/ml (p<0,01). A incidência de 20% encontrada, justifica a realização desta prova em todas as Pubarcas prematuras.

Familial Amyloidotic Polineuropathy and Systemic Lupus

Familial amyloidotic polineuropathy is a genetic disorder, leading to systemic amyloid deposits, manifested as sensory-motor and autonomic neuropathy. In the Portuguese classical form, the disease is evident at a young age, and causes death if no specific treatment is received. Variability in penetrance, age of onset and clinical course has been published; environmental and genetic factors are believed to contribute to this variability. The authors report a case of a 51-year-old white female, with a medical history of acquired angioedema, late-onset familial amyloidotic polineuropathy and systemic lupus erythemathosus. The authors consider that these associated diseases could modulate their expression.

GM1 Gangliosidosis, Late Infantile Onset Dystonia, and T2 Hypointensity in the Globus Pallidus and Substantia Nigra

BACKGROUND: GM1 gangliosidosis is a rare disease due to mutations in the GLB1 gene and autosomal recessive deficiency of b-galactosidase. There is considerable overlap between classical phenotypes and clinical and imaging findings, which are often difficult to interpret. PATIENT: The patient in this study had dysmorphism, dysostosis, progressive dystonia, and T2 hypointensity in the basal ganglia. Partially similar clinical and radiologic findings were described previously in two reports. CONCLUSIONS: T2 hypointensity in the globus pallidus should, in the appropriate clinical setting, lead to consideration of thediagnosis of GM1 gangliosidosis.
