BACKGROUND/AIM The importance of thyroid hormone on growth and development in children is well recognized. In addition, linear growth is highly dependent on the response of peripheral tissues to growth hormone, a process known as GH sensitivity, but little is known about the possible effects of T4 on this process. METHODS We determined the effect of(More)
AIM We investigated whether the insulin-like growth factor (IGF)-I response to growth hormone (GH) is regulated by body mass index (BMI) in short children with normal weight. METHODS We studied 37 prepubertal children with idiopathic short stature (ISS), comparing children with high-normal BMI (standard deviation scores, SDS 1.23 +/- 0.11, n = 20) and(More)
BACKGROUND/AIM Responsiveness to GH in target cells is mediated by its receptor, which activates the Janus kinase-2 (JAK2) and STAT5 (signal transducers and activators of transcription 5) leading to the expression of IGF-1 and IGFALS. The aim of this study was to compare the GH signaling pathway in newborns and prepubertal boys. SUBJECTS AND METHODS We(More)
Hyperphosphatemic familial tumoral calcinosis (HFTC) is an uncommon disease characterized by periarticular calcifications produced by the deposition of amorphous extraosseous calcifications of hydroxyapatite. It is associated with hyperphosphatemia due to increased tubular phosphate reabsorption, despite normal renal function and normal plasma PTH levels.(More)
OBJECTIVE Depot luteinizing-hormone releasing hormone (LHRH) agonist have been widely used for the treatment of central precocious puberty (CPP), but the optimal doses to obtain hormonal suppression are still unknown, especially in patients with higher weights. The goal of our study was to compare the efficacy of three leuprolide acetate (LA) preparations,(More)
BACKGROUND Congenital hypopituitarism is an uncommon cause of hypophyseal insufficiency It is less common than growth hormone deficiency which has an incidence of 1:4.000 to 1:8.000 live newborns. Early diagnosis of this condition is important to prevent impairment of cognitive function, poor growth and alterations in metabolic profile in these patients. (More)
INTRODUCTION Paraneoplastic pemphigus is an autoimmune disease associated with an underlying tumor. Several cases have been reported as unusual pemphigus vulgaris, erythema multiforme, or paraneoplastic bullous disease, but the incidence of the condition is unknown. Response to treatment is generally poor, with significant morbidity and mortality. This(More)
