Introduction: It is believed that hypoglycemia in the elderly is a dangerous condition and may result in stroke and death. We observed five female patients with insulinoma and over 20-year-long survival.Material: The material includes five female with the diagnosis of insulinoma. Patients’ age ranged from 78 to 91 years while disease duration ranged from 21 to 34 years.Methods: In all the patients, the diagnosis of insulinoma ...

IGF1 represents an important growth factor in pituitary physiology and pathology, also mediating the negative feed-back mechanisms on somatotroph axis. It has been previously demonstrated that IGF1 promotes cell viability in primary cultures of human non functioning pituitary adenomas, by a mechanisms involving, at least in part, mTOR signaling, which is involved in many pathways controlling proliferation. We aimed at investigating whether mTOR may mediate IGF1 effects also in...

Introduction: Medical therapy of acromegaly is indicated in patients who failed to achieve remission after surgery, with contraindication or refusal for surgical therapy or following radiotherapy in order to bridge the interval until complete remission.Objective: Evaluate the medical therapy – somatostatin analogs (SSA), dopamine agonist (DAs) and GH receptor-antagonist (Pegvisomant) – in acromegalic patients followed from 1988–2011.<p...

Introduction: Identification of molecular markers with a reliable prognostic value may greatly improve the management of patients with papillary thyroid carcinoma (PTC). Rac1b, a hyperactive splice variant of the small GTPase Rac1, was found to be overexpressed in colorectal, breast and lung cancer. It has been shown to sustain tumor cell survival in colorectal cancer and was reported to have a key role in the malignant progression of breast and lung tumors. The Rac1b tumorige...

Aims: Type 2 diabetes (T2DM) now affects a significant proportion of young people worldwide. ‘X-borough’ contains a strikingly young, diverse population with one of the highest rates of prevalence for adult T2DM in the UK. Our aims were to determine the prevalence and examine the characteristics of young people with T2DM in this population.Methods: Forty-four young people (<25 years) with T2DM were matched with an equal number of young peop...

Bilateral cervical exploration has been the gold standard in parathyroid surgery. Nowadays, the preoperative localization procedures have facilitated the minimally invasive surgery. This study aims to analyze the influence of thyroid disease in Tc99m-sestamibi scintigraphy (MIBI) results.A series of 154 patients with PHP who underwent parathyroidectomy was reviewed. Patients were divided into two groups: group 1 (G1, 58 patients) with thyroid diseases, a...

Background: Primary aldosteronism is a common cause of arterial hypertension, but its underlying molecular mechanisms are unknown. K+ is a key regulator of aldosterone secretion: it interacts with physiological secretagogues of aldosterone as angiotensin II (Ang II) end endothelin-1. In vivo genetic manipulation of a widely distributed class of channels, which generate background or ‘leak’ potassium (K+) currents, the twik-related acid-se...

Introduction: There is no known reliability about an undetectable recombinant human TSH (rhTSH) stimulated serum thyroglobulin (Tg) concentrations, predicts no long-term relapse, or the threshold of it. An rhTSH-stimulated serum Tg determination was made to all patients with DTC that maintained undetectable baseline Tg and negative imaging tests. We correlate their findings with their long-term evolution.Methods: We collected 91 patients with DTC, 73 wom...

Primary lymphomas of the thyroid are uncommon tumours, constituting fewer than 2% of all thyroid malignancies. For this reason their clinical features are not very well known. It seems that most of them arise in patients who have chronic autoimmune thyroiditis.From our patients with primary thyroid cancer since 1995, we selected those with pathological diagnosis of thyroid lymphoma. Epidemiological data, clinical features and response to treatment were a...

Introduction: After treatment with Iodine-131(I-131) in differentiated thyroid cancer, a diagnostic scintigraphy is performed. We selected three cases in which bronchiectasis appear as a false-positive on the scintigraphy after treatment with I-131.Case reports: Three women, respectively 62, 64 and 65 years old, being followed in the Endocrinology Department of our Institute, with the diagnosis of papillary carcinoma of the thyroid, were submitted to I-1...
