OBJECTIVE
This study was designed to assess the long-term effects of growth hormone (GH) replacement therapy on bone mass and bone turnover markers in children with isolated GH deficiency (IGHD) and multiple pituitary hormone deficiency (MPHD).
METHODS
Fifty children (35 IGHD, 15 MPHD) receiving GH
Growth hormone deficiency (GHD) is an important cause of decreased bone mass in childhood and adolescence. The role of other pituitary hormone deficiencies on bone mass is still a query in children. Thirty-nine children (28 with isolated GHD [IGHD] and 11 with multiple pituitary hormone deficiency
To evaluate the osteoblastic function in patients with multiple pituitary hormone deficiencies (M-PHD) and with isolated growth hormone deficiency (I-GHD), bone cells were cultured and the effects of 10(-8) M 1,25-dihydroxyvitamin D3 (1,25[OH]2D3) on parameters of cell proliferation, osteoblastic
BACKGROUND
Only few previous studies have assessed the effects of long-term growth hormone (GH) replacement therapy on bone mineral density (BMD) in adult patients with GH deficiency. The aim of this study was to investigate the effects of long-term GH therapy on bone metabolism and BMD.
METHODS
At
Conditions such as estrogen deficiency, skeletal unloading, and aging have all been demonstrated to have various effects on the proliferation and differentiation of bone marrow stroma-derived osteoprogenitor cells. Here we have sought to examine the effects of pituitary hormone deficiency on the
BACKGROUND
Hypophysectomy (HX) results in a cessation of bone growth and a decrease in bone metabolism. The purpose of this study is to examine the effect of HX on the static and dynamic histomorphometry of cancellous bone in the secondary spongiosa of the proximal tibial metaphysis in
Although radiation therapy has been universally accepted as treatment for primary intracranial germinomas, the optimal technique for both diagnosis and treatment continues to be a matter of controversy. We report a case of germinoma in the pineal region treated by interstitial brachytherapy. A
Recently, we have reported that a Prophet of Pit-1 homeodomain factor, Prop-1, is a novel transcription factor for the porcine follicle-stimulating hormone beta subunit (FSHbeta) gene. This study subsequently aimed to examine the role of Prop-1 in the gene expression of two other porcine
We report two cases of pituitary germinomas in two young men aged 13 and 21, revealed by insipidus diabetes associated with visual field defects or hypopituitarism. Neuroimaging of the first case was initially normal, then showed an infiltration of the stalk; the lesion of the second case appeared
A reciprocal relationship exists between the skin and the GH/IGF-I axis. Skin produces both IGF- I and vitamin D, and GH and IGF-I exert several actions in the skin. Reduced sweating and altered phosphor-calcium homeostasis are occasionally reported in subjects with GH deficiency Objective: The aims of the study were to estimate markers of mineral turnover and bone mineral density (BMD) in young women with central hypogonadism (CH) in comparison with healthy young and postmenopausal women, and to reveal the possible impact of different factors on BMD.Method: We
Lhermitte-Duclos disease is a rare hamartomatous tumor of the cerebellum resulting from a mutation in the phosphatase and tensin homolog (PTEN) gene: it has been reported in fewer than 10 infants. Rapamycin treatment has not yet been described in Lhermitte-Duclos disease. The infant underwent shunt
Gómez-López-Hernández (GLH) syndrome or cerebello-trigeminal dysplasia is a neurocutaneous syndrome whose etiology is unknown at the present time. We report two additional Brazilian patients, including the oldest one known to date (age 29). Here, we review the expanded phenotype in four patients
OBJECTIVE
Glucocorticoid (GC) therapy is associated with adverse effects on bone metabolism, yet the effects of different GC physiological replacement regimens in hypopituitarism are not well characterised. We aimed to assess the effect of three hydrocortisone (HC) replacement dose regimens on bone
We report the case of a composite malignant neoplasm consisting of germ cell tumor and B-cell non-Hodgkin's lymphoma occurring in the sella turcica of a young girl who presented with hypopituitarism. Routine hematoxylin and eosin-stained sections of a resected suprasellar tumor demonstrated a
