[Cognitive performance of preschoolers with Congenital Hypothyroidism enrolled in a follow-up program].

Unlabelled: The age at treatment initiation is decisive for limiting the neurological sequelae of Congenital Hypothyroidism (CH). Incorporating children into follow-up programs could be very helpful.

Objective: To evaluate the cognitive performance of preschool children with CH incorporated into a follow- up program.

Comparative study of brain damage and oxidative stress using two animal models of the shaken baby syndrome.

The objective was compare the morphological damages in brain and to evaluate the participation of oxidative stress, using two animal models of shaken baby syndrome (SBS). Five-day-old Wistar rats were used to develop two models of SBS as follows: Gyrotwister (GT) group was subjected to low intensity, high duration rotating movements and Ratshaker (RS) group made to undergo high intensity, low duration anteroposterior movements. Both groups presented respiratory distress, weight loss and shorter stature compared with the control group.
