Background: Turner syndrome (TS) is an important cause of short stature, however, there are a few reported cases of concomitant occurrence of TS and growth hormone deficiency (GHD).Case report: We report a 23-year-old female with concominat TS and GHD, also presenting partial FSH/LH deficiency and primary myxedema. The patient had iniatially been evaluated at the age of 15 for short stature and primary amenorrhea when she was diagnosed with Turner syndro...

Background: Germline mutations of the AIP tumour suppressor gene are associated with familial and sporadic pituitary adenomas, yet the tumorigenic mechanisms remain unclear. In addition, AIP protein expression in somatotroph adenomas from patients without AIP mutations correlates with clinical behaviour and somatostatin analogues responsiveness. Understanding the regulation of AIP gene expression will help uncover its pituitary tumour-suppressor role.Aim...

Introduction: PGs are rare neuroendocrine tumours (NETs), slowly growing, derived from the neural crest cells of the autonomous nervous system. Presenting symptoms are related to catecholamine hypersecretion or to mass effect. The optimal approach is dictated by size, symptoms and anatomical relationship of tumours with neurovascular structures.Aim: To describe a patient with bilateral carotid body and mediastinal carotid body PGs....

Background: PA is a clinical syndrome secondary to hemorrhage or infarction of pituitary tumour, presenting with sudden onset headache and oculomotor palsy. PA may be managed conservatively in patients without visual disturbances.Aim: To describe PA patients illustrating typical aspects and peculiarities.Results: Case 1, a 49 years old (yo) male, presented for loss of consciousness in the ER. MRI showed a giant pituitary tumour, wh...

Introduction: Idiopathic hypercalciuria is a risk factor for nephrolithiasis. Both renal stones and hypercalciuria are often associated with lower bone mineral density (BMD), but the relationship between these modifications is not completely understood. We aimed to evaluate some metabolic particularities possibly related to relapsing nephrolithiasis in young male patients.Methods: We performed a cross-sectional study including a group of 30 young male pa...

Introduction: Hyponatremia, defined as a serum sodium concentration below 135 mEq/l, has a heterogeneous etiology, the main endocrine causes includind the syndrome of inappropiate antidiuresis (SIAD), adrenal insufficiency and severe hypothyroidism.Materials and methods: Clinical, hormonal and imaging evaluationAim: To present a case of hyponatremia leading to the diagnosis of a large pituitary tumorCase pres...

Pasireotide (Pas) is a multireceptor-targeted somatostatin analogue approved for the treatment of patients with Cushing’s Disease (CD) who fail or are poor candidates to surgery. Pas markedly improves signs and symptoms of the disease, reduces urinary free cortisol (UFC) up to its normalization in 55% of patients and pituitary tumour size in up to 100%. Here we present a patient with severe recurrent CD treated with Pas and showing opposite results between hormonal levels...

Introduction: Intrasellar arachnoid cysts are rare and clinically resemble nonfunctional pituitary adenomas. Arachnoid cysts should be considered in the differential diagnosis of cysts developing in the sellar region, together with cystic pituitary adenoma, craniopharyngioma, epidermoid cysts, and Rathke’s cleft cysts. Symptomatic cysts are operated but can recurr.Case presentation: We present 2 cases of compressive intrasellar arachnoid cysts occur...

Introduction: Pituitary incidentaloma (PitInc), defined as an unsuspected mass observed on imaging studies performed for unrelated conditions. Most such lesions are not clinically significant at initial evaluation and current guidelines recommend periodic follow-up.Aim: To present a rare case of delayed onset of acromegaly in a patient with a nonfunctioning PitInc, raising the question of the utility of prolonged follow-up of PitInc.<p class="abstext...

Introduction: Both TSH and prolactin serum levels within normal range were previously reported to be associated with metabolic parameters.Aim: To analyse the connections between serum levels of prolactin, TSH, and insulin resistance in polycystic ovary syndrome patients.Material and methods: 322 PCOS patients (mean age 24.3±5.16 years and mean BMI 28±7.57 kg/m2) with normal serum prolactin and without thyroid d...
