[Neurological, neuropsychological, and ophthalmological evolution after one year of docosahexaenoic acid supplementation in phenylketonuric patients].

INTRODUCTION. Phenylketonuria (PKU) is an autosomal recessive metabolic disease caused by a deficiency of phenylalanine hydroxylase. The dietary therapy for the effective management of PKU, in particular the restriction of high-protein foods of animal-origin, compromises patients' intake of fat and distorts the n-3:n-6 ratio of essential fatty acids in the diet.

[Diffusion-weighted imaging in pediatric central nervous system infections].

Aim: To report the findings in diffusion-weighted images (DWI) and its potential contribution to the early diagnosis and prognosis of neurological sequelae.
