Aim: To assess cumulative incidence and risk factors for amiodarone-induced thyroid dysfunction (AITD) in a large cohort of Romanian subjects.Subjects and methods: One hundred and forty-four patients (59 M/85 F), mean age 61.4±0.9 years, treated 2.4±0.2 years with amiodarone were assessed for TSH, TT3, TT4 (immunoradiometric assays) and FT4, TPO Ab (microenzymatic immunoassays). Thirty-three patients were reside...

Background: Acute right ventricular dysfunction (RVD) on echocardiography (ECHO) is critical for risk stratification in pulmonary embolism (PE). Plasma BNP, a consecrated marker of left ventricular dysfunction, could represent a valuable biomarker of RVD in PE.Aim and objective: Assessment of plasma BNP levels in patients with PE in relationship with right ventricular (RV) function evaluated by ECHO.Methods: Prospective study of 70...

Aim: To set up, in acromegaly without diabetes mellitus, a correlation between the disease activity in GH-secreting adenoma (AA) - assessed by minimum GH serum level during an oral glucose tolerance test (OGTT) - and severity of insulin resistance (IR), assessed by HOMA-IR index.Methods: 75 out of 88 consecutive patients with acromegaly hospitalized in our department were included in this study. 13 patients proved to have diabetes mellitus and were exclu...

Introduction: Sox2 is a widely expressed marker of progenitor and stem cells in various organs, strongly expressed within Rathke’s pouch and the neural ectoderm. It exerts a critical role in the early stages of pituitary development but it is still expressed in the adult gland. Sox2 expression in pituitary adenomas and its possible correlation with clinicopathologic characteristics have not been investigated so far.Aim: To evaluate the immunohistoch...

Introduction: An improvement of survival in patients with acromegaly was claimed in the last years, with multimodal new therapies.Aims: To assess cure rates of different therapeutic protocols and the impact of these therapies on survival.Methods: 334 patients (224 F/110 M, mean age 48.1±0.7 years) with acromegaly admitted in a single Neuroendocrinology Department between Jan 2001 and Dec 2013 were retrospectively studied by GH...

Background: Suitable postoperative radiotherapy (RT) of nonfunctioning pituitary macroadenomas (NFMAs) is still controversial, subjected to rapid technical and medical progress.Patients and methods.: We studied 87 patients with NFMA to identify factors affecting tumor control such as the time of RT and tumor pathology. Partial pituitary surgery was performed either by transfrontal (30 patients) or transsphenoidal (57 patients) approach. An immunoperoxida...

Introduction: The heel quantitative ultrasound (QUS) is useful tool in the assessment of fracture risk especially if cost issues are involved. It might be helpful in follow-up the patients who will not be treated with anti-osteoporotic drugs.Aim: To present the bone evaluation (DXA) after a period of time in patients who are initially assesed by both DXA and QUS.Material and patients: This is a prospective pilot study in a group of...

Background: PCOS-associated increased metabolic risk may be selective, owing to its heterogeneous nature. Identification of high-risk individuals could enable better studies and prevention of complications.Aim: To characterize the metabolic risk, as metabolic syndrome (MetS), of specific PCOS subphenotypes.Subjects and methods: Romanian PCOS (Rotterdam criteria) and 64 controls, 18–35 years. PCOS subphenotypes were defined: i)...

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...
