Background: Craniopharyngioma (CP) are the most common sellar tumors in children. Patients often develop excessive weight gain and obesity due to several factors as involvement or damage of the hypothalamus. Previous studies on the weight development in craniopharyngioma patients have shown an increase in weight before and in the first 10 years after diagnosis leading to an impaired quality of life. The long-term weight development in these patients has not been investigated t...

Aim: The Genetics and Neuroendocrinology of Short Stature International Study (GeNeSIS) is an open-label multinational observational study which collects information on management, clinical outcomes and treatment safety of children with growth disorders. Here we present descriptive data from the Greek cohort.Methods and results: In Greece, 211 children (44.5% females, 136 naive to GH treatment at study entry and 18 not GH-treated) have been enrolled, aft...

Ghrelin, the endogenous ligand of GH secretagogue receptor type 1a, has emerged as pleiotropic modulator of diverse biological functions, including energy homeostasis and recently, reproduction. The effects of i.c.v. administered ghrelin on morphological characteristics of pituitary FSH- and LH-cells were examined in adult male Wistar rats. The animals were randomized in two groups: control and experimental group, each consisted of seven animals, and implanted with an i.c.v. c...

Introduction: Generously supported by IPSEN)-->Surgical treatment of pituitary adenomas (PA) may affect hormone situation.Objective: To evaluate the frequency of hypopituitarism and investigate the potential predictors of worsening or improving pituitary function after PA surgery.Methods: Retrospective analysis of all PA operated in our hospital between 2001 and 2010.<p class="abstext...

Case of 33 years old male patient with an unremarkable past medical history, who after a car accident, a cystic nodular right neck mass was incidentally found by MRI of cervical spine. Physical examination revealed a mildly tender right neck mass. He was clinically and biochemically euthyroid. Denied history of neck irradiation. No family history of thyroid disease or thyroid cancer. Excisional biopsy of right neck mass showed metastasic well differentiated papillary carcinoma...

Somatotroph adenomas causing acromegaly are histologically classified into densely and sparsely granulated subtypes and an intermediate, mixed type. Although the different subtypes are not currently taken into account when making decisions about the management of acromegaly, there is growing evidence that the subtypes represent clinically different entities.In a cohort (n=52) of somatostatin-naïve patients with acromegaly, sparsely granulat...

Background: Familial isolated pituitary adenoma (FIPA) is an autosomal dominant condition with incomplete penetrance. Heterozygote mutations have been identified in the aryl-hydrocarbon receptor interacting protein (AIP) gene in 20% of FIPA families causing young-onset aggressive tumours.Aims: The aim of this study was to perform comparative gene expression microarray analysis of familial AIP positive and AIP negative adenomas and compare them to sporadi...

Man-made chemicals in our environment may be harmful, in particular for the developing child with potential irreversible effects into adulthood. Considering the rapid increase in use and distribution of such chemicals over the past decades, it is tempting to speculate whether these changes contribute to the increase in some health problems.The prevalence of hypospadias and cryptorchidism in boys has increased in some countries, parallel to adult testicul...

Introduction: The genetic mechanisms underlying adrenocortical tumor development are still largely unknown. We used high-resolution single nucleotide polymorphism (SNP) microarrays to detect copy number alterations (CNAs) and copy neutral losses of heterozygosity (cnLOH) in cortisol-secreting adrenocortical adenomas (ACAs). We focused on microalterations aiming to discover new candidate genes involved in early tumorigenesis and/or autonomous cortisol secretion.<p class="ab...

Background data: Laparoscopic adrenalectomy has became in the last decade “gold standard” for treating of adrenal tumors with diameters smaller than six cm. In addition, one should note than larger tumors or potentially malignant tumors can now also be removed laparoscopically, with virtually no complication.Objective: The authors evaluate the effectiveness of laparoscopic adrenalectomy for a large adrenal tumors.Methods:...
