1. Relevância das variações anatômicas das cavidades nasais no acesso transesfenoidal endoscópico / Relevance of nasal anatomical variations for endoscopic transsphenoidal approach
Introdução: As cavidades nasais constituem a via de acesso à hipófise na cirurgia transesfenoidal endoscópica. Deste modo, alterações naturais ou adquiridas da anatomia nasal podem prejudicar a cirurgia. Objetivos: Estudar as variações anatômicas das cavidades nasais, principalmente desvio do septo, correlacionando-as com a visibilidade no acesso t

2. Análise dos genes GHRH e GL12 em pacientes com deficiência de hormônio do crescimento congênita / GHRH and GLI2 genes analysis in patients with congenital growth hormone deficiency
Introduction: Alterations in genes related to GH secretion and pituitary organogenesis have been identified in patients with congenital GH deficiency (GHD). However, in only few cases of GHD the etiology has been established. GH-releasing hormone (GHRH) is an obvious candidate to explain isolated GH deficiency (IGHD). Previous reports in the literature did n

3. Poland's syndrome associated with growth hormone deficiency.
A 9 year old boy with Poland's syndrome (absence of the left pectoralis major muscle associated with an ipsilateral malformation of the hand) and isolated growth hormone deficiency, owing to anatomical abnormalities of the pituitary gland, is described. MRI brain scan showed severe hypoplasia of both the sella and anterior lobe of the pituitary gland with ab

4. A homozygous mutation in HESX1 is associated with evolving hypopituitarism due to impaired repressor-corepressor interaction
The paired-like homeobox gene expressed in embryonic stem cells Hesx1/HESX1 encodes a developmental repressor and is expressed in early development in a region fated to form the forebrain, with subsequent localization to Rathke’s pouch, the primordium of the anterior pituitary gland. Mutations within the gene have been associated with septo-optic dysplasia
