Introduction: Gastrinoma is rare gastrin-secreting neuroendocrine tumor (NET), usually located in the pancreas or duodenum. The most common presentations of gastrin secreting tumor is Zollinger-Ellison Syndrome (ZES). Only about 10% of patients have non demonstrable ulcer.Case presentation: A 67 years old female, with premature menopause, mild hypothyroidism with optimal replacement treatment, osteopenia and history of chronic gastritis, is admitted to o...

Introduction: Pituitary tumours may interfere with fertility and pregnancy may be uncommon in these cases, but some patients can conceive spontaneous. Also in pregnancy, due to the physiologic changes of the pituitary gland, gradual volume increase and cellular hyperplasia that target hormonal secretion, the evaluation of the pituitary function is very complex.Clinical cases: We present 5 cases of female patients (24 – 35 years old) that were diagn...

Background: Primary hyperaldosteronism or Conn’s syndrome is one of the adrenocortical causes of hypertension, alongside hyperdeoxycorticosteronism, apparent mineralocorticoid excess and Cushing syndrome. The two types of hypertension-inducing adrenocortical syndromes (Conn’s and Cushing) are extremely rare to be decribed in the same patient. We describe a case of a patient with clinical and biochemical evidence of Conn’s syndrome due to a left adrenal adenom...

Introduction: Patients with non-functioning pituitary adenomas (NFPA) and hipopituitarism had a reduced life expectancy.Aims: To assess mortality ratio and to identify prognostic factors associated with mortality in patients with NFPA in the last decade.Methods: A 196 patients (83 F/113 M, mean age 52.7±0.9 years) with NFPA admitted in a single Neuroendocrinology Department between January 2001 and December 2010 were retrospec...

Background: A large spectrum of AIP gene mutations has been identified in familial and sporadic pituitary adenomas (PA) with over 70 different mutations described to date. c.47G>A, p.R16H is an AIP exon 1 variant of unknown significance, its contribution to pituitary adenoma development being controversial.Aim: Characterization of p.R16H prevalence in a large Romanian cohort of PA patients and controls.Patients and methods: spo...

Human adipose tissue provides abundant source of mesenchymal stem cells, which can be easily and safely harvested as compared with human bone marrow.The aim of this study was to differentiate a viable osteoblast and adipocyte cell culture from mesenchymal stem cells, an experimental model to study the interrelation between adipocytes and bone forming cells, osteoblasts.Materials and methods: Subcutaneous adipose tissue liposuction ...

Introduction: The pathogenesis of pituitary adenomas is incompletely understood. It was recently demonstrated that mutations in AIP, a novel tumor suppressor gene, are causing the familial isolated pituitary adenoma syndrome. Although initial data suggested that AIP mutations are rare in non-familial cases, a recent study demonstrated an increased prevalence in young sporadic macroadenoma patients.Aim: To perform a systematic screening of AIP mutations i...

Introduction: Monoclonality of pituitary adenomas is an established fact. Still, there are exceptions and polyclonality may correlate with aggressive tumor behavior. In order to test association of clonality with pituitary adenoma characteristics in a series from Romania, we implemented a protocol for X-chromosome inactivation analysis at the androgen receptor (AR) locus (HUMARA) and validated it in a number of tumor samples.Objective: To establish and v...

The structural and functional effects upon arterial vessels of GH and IGF1, chronically elevated in active acromegaly, are risk factors for premature atherosclerosis, but current therapies can normalize GH and IGF1 production.Aims: To evaluate if carotid wall alterations in acromegaly are reversible after disease control.Material and methods: Fifteen patients with controlled acromegaly (CA) after multimodal therapy (45.5±</...

AbstractThyroid angiosarcoma is an aggressive and very rare type of thyroid malignancy originally diagnosed in iodine-deficient areas. The prognosis is poor and in most cases surgery proved to be inefficient. The fine needle aspiration biopsy (FNAB) and histology can rarely differentiate angiosarcoma from anaplastic carcinoma, and the final diagnosis is based on immunopositivity for vascular markers and absence of epithelial markers. We present he...
