ABSTRACT
The pituitary gonadotropic responsiveness to acute and prolonged administration of LH/FSH-releasing hormone (LHRH) were assessed in 6 patients with untreated congenital virilizing adrenal hyperplasia (partial 21-hydroxylase deficiency). The oldest subjects had normal response in comparison to females at the midfollicular phase, to the acute infusion of 25 ug LHRH regarding both gonadotropins whereas LH secretory area was decreased during the prolonged (100 ug LHRH in 8 hours) infusion with normal FSH secretion. The two youngest subjects, with higher steroid levels in our series, were either unresponsive on both ways of testing or presented pre-pubertal response.

Uma paciente com doenca de Cushing apresentou normalizacao do eixo adrenal pituitario apos resseccao tranfenoidal de micro-adenoma pituitario. Apos 9 meses houve recidiva da doenca que foi curada apos irradiacao externa havendo inducao de hipopituitarismo hipotalamico, sugerindo outro novo crescimento de tumor que poderia ser hipotalamo-dependente e/ou destruicao do tumor e lesao do hipotalamo concomitantes. Outra possibilidade poderia ser a existencia de uma disfuncao hipotalamica primaria com producao anormal de ACTH pela hopofise
