Background: Cushing’s syndrome is the most common cause of endogenous hypercortisolism that results from the excessive exposure to glucocorticoids. Even though this syndrome is represented by a constellation of clinical signs and symptoms, the most common next features are the truncal obesity and the moon facies, making it hard not to be recognized. It is more common in women (F/M=5-8:1) with an avarage age of 20–40 years.Case Presentation: A 3...

Introduction: Insulinoma is a rare tumor that causes spontaneous fasting hypoglycemia in a supposedly healthy adult. Mostly these tumors are single and benign, few are malignant and a minority is represented by multiple adenomas. The treatment of choice is surgical removal of the insulinoma, which cures the condition in the majority of cases. However, after performing the surgery, less than 10% of patients either develop diabetes mellitus or continue to have persistent hypogly...

IntroductionProlactinomas are the most common hormone-secreting pituitary tumours encountered in the clinic. They are usually treated with dopamine agonists (DA): bromocriptine (BRC) and cabergoline (CAB), which are highly effective in the majority of cases. DA resistance is the failure to achieve normal levels of prolactin and, or reduction of the adenoma with at least 50%.Aimto assess the prevalence of the ...

IntroductionPituitary apoplexy is a rare entity characterized by abrupt hemorrhage and/or ischaemia of the constituents of sella turcica. It usually occurs in a previously unsuspected pituitary tumor. It may have an acute or subclinical presentation and it may represent a neuroendocrinological emergency.AimThis study aims to analyze predisposing or precipitating factors, clinical status, imaging and hormonal ...

Introduction: Somatotroph pituitary adenomas (PAs) represent 10-15% of all resected PAs, exhibiting immunohistochemical (IHC) positivity for GH (growth hormone) and PIT-1 transcription factor (TF). The histopathological (HP) and IHC variability of each PA influences the phenotype, radiological features, and therapy response.Materials and methods: The study included 33 patients with acromegaly, with men: women ratio of 17:16. The HP-IHC characteristics we...

Introduction: Parathyroid carcinoma represents a very rare cause of primary hyperparathyroidism. It can be sporadic (most of cases), but also can occur in association with certain syndromes (multiple endocrine neoplasia, hyperparathyroidism-jaw tumor syndrome or isolated familial hyperparathyroidism).Case report: An 18-year-old woman was referred to the endocrine clinic because of a severe hypercalcemia, detected in the orthopedic surgery department, whe...

Background and Aims: GH receptor antagonist (Pegvisomant –PEG) has been shown to obtain IGF1 normalization in 60–90% of patients with acromegaly in clinical trials. The aim of the study is to evaluate real life response and side effects of PEG treatment in monotherapy versus combined with somatostatin analogues and/or cabergoline in patients with somatostatin analogues resistant acromegaly.Methods: We included 40 patients (22F/18 M) cons...

Introduction: Pituitary apoplexy is a rare complication in 2%-12% of pituitary adenomas, due to sudden hemorrhage or infarction. Patients with signs of meningeal irritation, important visual field defects, ocular paresis, decreased unilateral or bilateral visual acuity or altered consciousness are treated by neurosurgical intervention, while patients without these signs could be managed conservatively.Aim: To present a series of 4 cases with pituitary ap...
