Molecular mechanisms of nongenomic glucocorticoid actions: the role of human glucocorticoid receptor S-palmitoylation

Nicolaides Nicolas C , Roberts Michael L , Kino Tomoshige , Katsantoni Eleni , Sertedaki Amalia , Chrousos George P , Charmandari Evangelia

Background: In humans, glucocorticoids (GCs) regulate a broad spectrum of physiologic functions, exerting both genomic and nongenomic actions through their ubiquitously expressed glucocorticoid receptor (hGR). The rapid nongenomic actions of GCs are likely to be mediated by membrane hGRs that transduce the glucocorticoid signal via activation of kinases. S-palmitoylation plays an important role in plasma membrane localization and occurs through a highly conserved nine amino ac...

Background: The short stature homeobox-containing (SHOX) gene, located in the telomeric pseudoautosomal region 1 (PAR1) on the short arm of both sex chromosomes, is important for linear growth.Objective and hypotheses: The aim of our study was to evaluate the presence of SHOX gene deletions/point mutations in children with short stature in order to understand the role of SHOX gene in idiopathic short stature (ISS) and estimate its frequency.<p class=...

Childhood Craniopharyngioma: Changes of Treatment Strategies in Multinational Trials During the Last 12 Years

Hoffmann Anika , Warmuth-Metz Monika , Gebhardt Ursel , Pietsch Torsten , Pohl Fabian , Kortmann Rolf-Dieter , Calaminus Gabriele , Muller Hermann L

Background: Despite high survival rates in childhood craniopharyngioma, prognosis is frequently impaired due to sequelae. Radical surgery was the treatment of choice for several decades. However, even at experienced surgical facilities radical surgery can result in hypothalamic disorders such as severe obesity.Objective and hypotheses: We analyzed, whether treatment strategies for childhood craniopharyngioma patients recruited in German studies (KRANIOPH...

Growth Hormone Treatment in Children with SGA During a 5-Year Period, Assessment of Auxological Development and Insulin Resistance

Lopez-Siguero J P , Martinez-Aedo M J , Bermudez J A , Cabrinety N , Bosch J , Lechuga J L , Torralba R

Background: Treatment with GH of children born SGA allows an increase in growth velocity (GV) and improves adult height. Increased insulin resistance has been described in these patients, which reverts after interrupting GH administration. However, long-term metabolic consequences are not clearly established.Objective and hypotheses: Describe insulin resistance (HOMA-IR index) and auxological development (GV and height) in SGA children treated with GH fo...

Pseudohypoaldosteronism Type 1: Role of Urinary Steroid Profiling in Specific and Early Diagnosis: Lessons in Differential Diagnosis of PHA1 vs PHA2 (Renal Tract Anomaly)

Abbot V , Ghataore L , Pieterse D J , Chapman S , Kapoor R R , Taylor N F , Buchanan C R

Background: Pseudohypoaldosteronism type 1 (PHA1) is a rare disorder of neonatal salt loss unresponsive to mineralocorticoids, requiring salt supplementation. It results from resistance of kidney and/or other tissues to mineralocorticoids, arising from mutations in genes encoding mineralocorticoid receptor (MR: NR3C2; autosomal dominant), or epithelial sodium channel (ENaC) genes (SCNN1A/B/G; autosomal recessive). Milder clinical phenotype associates with ren...

Survival, Hypothalamic Obesity, and Neuropsychological/Psychosocial Status after Childhood-Onset Craniopharyngioma: Newly Reported Long-Term Outcomes

Sterkenburg Anthe S , Hoffmann Anika , Gebhardt Ursel , Warmuth-Metz Monika , Daubenbuchel Anna M M , Muller Hermann L

Background: Quality of life and long-term prognosis are frequently, often severely impaired in craniopharyngioma (CP) patients.Objective and hypotheses: Knowledge of risk factors for long-term outcome is important for optimisation of treatment.Method: Overall survival (OS) and progression-free survival (PFS), BMI, neuropsychological status (EORTCQLQ-C30, MFI-20), and psychosocial status were analysed in 261 patients with childhood-...

Hydrocephalus and Hypothalamic Involvement in Paediatric Patients with Craniopharyngioma or Cysts of Rathke’s Pouch: Impact on Long-term Prognosis

Daubenbuchel Anna M M , Hoffmann Anika , Gebhardt Ursel , Warmuth-Metz Monika , Sterkenburg Anthe S , Muller Hermann L

Background: Paediatric patients with sellar masses such as craniopharyngioma (CP) or cyst of Rathke’s pouch (CRP) frequently suffer disease- and treatment-related sequelae.Objective and hypotheses: We analysed the impact and prognostic relevance of initial hydrocephalus (HY) and hypothalamic involvement (HI) on long-term survival and functional capacity (FC) in children with CP or CRP.Method: Using retrospective analysis of pa...

Serum AMH Levels are Lower in Healthy Boys Who Develop Pubertal Gynaecomastia

Mieritz Mikkel G , Hagen Casper P , Almstrup Kristian , Petersen Jorgen H , Raket Lars L , Sommer Stefan H , Juul Anders

Background: Pubertal gynaecomastia is thought to be a clinical sign of an oestrogen-androgen imbalance, affecting up to 60% of boys. In most cases no underlying endocrinopathy can be identified. In boys, Anti-müllerian hormone (AMH) is produced by immature Sertoli cells and circulating level decreases as testosterone increases during pubertal maturation. In a previous cross sectional study we found significant lower levels of AMH in boys with pubertal gynaecomastia (Mieri...

Conservative Treatment Allows Substantial Improvement of Neonatal Cushing Syndrome in McCune Albright Syndrome, a 2 Year Follow-up

van Nieuwaal Nancy HG , Houwen Roderick H J , van der Grinten Hedi L Claahsen , Stuart Annemarie A Verrijn

Background: McCune Albright syndrome (MAS) is defined by the classic triad of precocious puberty, fibrous dysplasia of bone and café au lait skin pigmentation. However, the clinical spectrum is often more variable due to mosaic distribution of the postzygotic GNAS-mutation. Hypercortisolism occurs in a minority (5%) of patients. It is most frequently caused by nodular adrenal hyperplasia and can be life-threatening. Decisions on whether clinical management should be conse...

AIP Polymorphism in Familiar Isolated Pituitary Adenomas: Case Report

Viale Maria Lorena , Hernandez Claudia L , Rampi Maria Gabriela , Serra Maria Pia , Figueroa Veronica , Day Patricia Fainstein , Brunetto Oscar H

Background: Familiar isolated pituitary adenomas (FIPA) encompasses the familiar occurrence of isolated pituitary adenomas outside the setting of syndromic conditions such as MEN1 and Carney’s complex, and comprise about 2–3% of pituitary adenomas. About 20% of FIPA have mutations in the aryl hydrocarbon receptor interacting protein gene (AIP), usually associated with a worse outcome.Objective and hypotheses: Evaluate the presence of AIP gene m...
