13. A boy with Prader-Willi syndrome: unmasking precocious puberty during growth hormone replacement therapy
SUMMARY Prader-Willi syndrome (PWS) is a genetic disorder frequently characterized by obesity, growth hormone deficiency, genital abnormalities, and hypogonadotropic hypogonadism. Incomplete or delayed pubertal development as well as premature adrenarche are usually found in PWS, whereas central precocious puberty (CPP) is very rare. This study aimed to repo

14. Clonidine-stimulated growth hormone concentrations (cut-off values) measured by immunochemiluminescent assay (ICMA) in children and adolescents with short stature
OBJECTIVES: To establish cut-off values for growth hormone concentrations using clonidine as a secretagogue and an immunochemiluminescent assay as the method of measurement and to analyze the response time as well as the influence of gender, nutritional status and pubertal stage. METHODS: A total of 225 tests were performed in 3 patient groups, categorized

15. Male-female differences in 6-sulfatoxymelatonin excretion in hypopituitary patients
ABSTRACT Objective To evaluate melatonin secretion in adult hypopituitary patients with Growth Hormone deficiency (AGHD) on and off replacement therapy. Subjects and methods We studied 48 subjects: 12 (6 males) untreated AGHD (AGHDnt), 20 (10 males) treated AGHD (AGHDt) and 16 healthy subjects (8 males) as control group (CG). We measured urinary 6-sulfat

16. Pituitary deficiency after aneurysmal subarachnoid hemorrhage
OBJECTIVE: Aneurysmal subarachnoid hemorrhage puts patients at high risk for the development of pituitary insufficiency. We evaluated the incidence of pituitary dysfunction in these patients and its correlation with clinical outcome. METHODS: Pituitary function was tested in 66 consecutive patients in the first 15 days after aneurysmal subarachnoid hemorr

17. EFEITO DO TRATAMENTO COM HORMÔNIO DE CRESCIMENTO NA BAIXA ESTATURA IDIOPÁTICA COM DEFICIÊNCIA MODERADA DO GH OU INSENSIBILIDADE PARCIAL AO GH. / EFFECT OF THE TREATMENT WITH GROWTH HORMONE IN IDIOPATHIC SHORT STATURE WITH MODERATE GH DEFICIENCY OR PARTIAL GH INSENSITIVITY.
A baixa estatura idiopática é um conjunto heterogêneo de condições sem evidentes alterações hormonais ou etiologias definidas. Pode incluir a insensibilidade parcial ao GH (IPGH) e a deficiência moderada de GH (DMGH), ambas com concentrações baixas de fator de crescimento semelhante à insulina tipo I (IGF-I) e hiper ou sub-resposta do GH aos teste

18. 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

19. Growth hormone response to growth hormone-releasing peptide-2 in growth hormone-deficient Little mice
OBJECTIVE: To investigate a possible direct, growth hormone-releasing, hormone-independent action of a growth hormone secretagogue, GHRP-2, in pituitary somatotroph cells in the presence of inactive growth hormonereleasing hormone receptors. MATERIALS AND METHODS: The responses of serum growth hormone to acutely injected growth hormone-releasing P-2 in lit/l

20. Pesquisa de mutações no gene do receptor do secretagogo de hormônio de crescimento (GHSR) em crianças com baixa estatura idiopática e deficiência isolada de hormônio de crescimento / Growth hormone secretatogue receptor gene (GHSR) analysis in patients with idiopathic short stature (ISS) and patients with isolated growth hormone deficiency
A ghrelina, hormônio secretado principalmente por células gástricas, liga-se ao seu receptor, o receptor de secretagogo de GH (GHSR - Growth hormone secretagogue receptor), localizado no hipotálamo e na hipófise, estimulando a síntese e secreção do GH. Recentemente foram identificadas mutações no gene GHSR em crianças com baixa estatura idiopátic

22. Characterization of the physical and mechanical properties of femoral bone defects filled with polyanionic collagen scaffolds in ovariectomized rats
The aim of this study was to evaluate the effect of scaffolds native or polyanionic collagen matrix (submitted to alkaline treatment for 48 or 96 hours, PCM48 or PCM96, respectively) on the repair of osteoporosis bone fractures resulting from the gonadal hormone alterations caused by ovariectomy in rats undergoing hormone replacement therapy. The physical an

O objetivo deste trabalho foi aprofundar a avaliação da dissociação entre a presença de marcadores de risco cardiovascular (CV) e a ausência de doença CV (DCV) na deficiência isolada do GH (DIGH) por mutação no gene do receptor do hormônio liberador do GH. Foi realizado um protocolo com duas etapas. No primeiro experimento, foram avaliados os nív

24. Nitric oxide contributes to learning and memory deficits observed in hypothyroid rats during neonatal and juvenile growth
INTRODUCTION: Severe cognitive impairment follows thyroid hormone deficiency during the neonatal period. The role of nitric oxide (NO) in learning and memory has been widely investigated. METHODS: This study aimed to investigate the effect of hypothyroidism during neonatal and juvenile periods on NO metabolites in the hippocampi of rats and on learning and m
