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: Adrenal carcinomas are rare tumor. It has an estimated incidence of ~0.5–2 new cases per million people per year. Just 25% of adults with hormone-secreting adrenal carcinomas present overproduction of both glucocorticoids and androgens. Women develop adrenal carcinomas more often than men.Objectives: We report a case of 47-year-old female presented with weight gain, generalized weakness and hypertension for the last 6 months. Phy...

Multiple endocrine neoplasya type 2 (MEN-2) is a rare hereditary complex disorder caused by a germline activating mutation of the RET proto-oncogene. The estimated prevalence is approximately 1:30.000. Three clinical forms have been described depending on the phenotype: MEN2A (80%), MEN2B and familial medullary thyroid carcinoma (MTC).Clinically, MEN2A present with MTC (80–100%), unilateral or bilateral pheocromocytoma (40%) and primary hyperparath...

Introduction: There are many side effects caused by mitotane and several are registered at drug levels lower than therapeutical doses.Aim: We observed the mitotane side effects in patients treated for adrenal cancer.Materials and methods: This is a retrospective study in adrenal tumors.Results: Out of 56 patients included in a database with adrenal tumors, we found eight patients (14.25%) with adrenal cancer ...

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...

Introduction: Pituitary incidentaloma is a relatively frequent imagistic finding. Since no therapy is necessary, the follow up protocol is the most important in patients’ approach.Aim: We present a study in patients diagnosed with pituitary incidentaloma, admitted in I.Parhon, Bucharest, between 1999 and 2011.Patients and method: This is a retrospective study in 140 patients, diagnosed with pituitary incidentaloma based on CT ...

Introduction: The concentrations of pituitary hormones in the cerebrospinal fluid (CSF) are much lower that their serum counterpart.Aim: To study the CSF access for pituitary glycoprotein hormones (GPH) in patients with pituitary adenomas (PA).Patients and methods: In 221 cases submitted to transsphenoidal surgery for PA (85 acromegaly – ACM, 92 nonfunctioning pituitary adenomas – NFA, 44 prolactinomas – PRM) the sur...

Introduction: Parasellar extension of macroprolactinomas defined on imaging criteria was reported to be an independent predictor of hormonal resistance to dopamine agonists (DA).Methods: Two hundred and twelve patients with macroprolactinomas (87 M/125 F), treated with DA for 5 years median period; prolactin (fluoroimmunoassay or chemiluminescence), CT scan and/or MRI with contrast agents were performed; maximum diameter evolution was reported.<p cla...

Pituitary apoplexy is a rare syndrome due to hemorrhagic infarction of a pituitary adenoma. We analyze the circumstances of diagnosis, clinical features and evolution in a retrospective review of patients with pituitary apoplexy admitted between 2000 and 2010, diagnosed by pathological exam and/or suggestive imaging for pituitary haemorrhage.Results: From 31 patients with pituitary apoplexy (11 women, 20 men) with a mean age of 48 years at diagnosis (20&...

Introduction: Turner syndrome is a common cause of dwarfism and hypogonadism as is pituitary failure. However the association of the two is rarely thought and reported in the literature. We present two cases of women with hypogonadism diagnosed with Turner syndrome with various degrees of pituitary insuficiency.Case report: The first case presented at 16 years with secondary amenorrhea and showed slightly disharmonic dwarfism. A hypogonadotropic hypogona...
