Introduction: Cushing syndrome could be missed initially, especially when the presenting features are common in the general population. Before proceeding to the hormonal tests we have to consider that recent studies have shown that up to 50% of patients with CD have different degrees of altered glucose metabolism, up to 80% of CS patients have hypertension independently of their age and sex and hypercorticism changes bone structure and causes vertebral fractures in approximate...

Introduction: Malignant melanoma is a challenging illness for researchers due to unknown hormonal disorders involved in promoting/developing this disease. Some authors accept nowadays, that prolactin is involved in extrapituitary carcinogenesis.The authors aimed to study the status of prolactin in patients with melanocytic lesions and the impact of surgical removal on prolactinemia.Method: The study included 128 adults with melanom...

Background: Low-serum concentrations of 25(OH)-vitamin D are associated with insulin resistance in adults. Recent in vitro studies have suggested that vitamin D may play a role in the regulation of adiponectin, leptin and resistin; since all these adipokines are related to insulin sensitivity modulation, they might represent a link between vitamin D status and insulin resistance.Aim: To identify possible correlations between 25(OH)-vitamin D ser...

Background: Hyponatremia is a common electrolyte abnormality, especially in elderly, hospitalized patients, with a prevalence of severe hyponatremia (<125 mmol/l) up to 6–8%. Pituitary insufficiency (TSH+ACTH) may be difficult to diagnose, but it is important to differentiate it from SIADH and cerebral salt wasting syndrome.Aim: To describe the aetiology and outcome of patients with hyponatremia due to pituitary insufficiency in a tertiary endoc...

Introduction: The prevalence of obesity in children and adolescents has dramatically increased over the last 20–30 years.Childhood overweight is associated with higher risk of obesity into adulthood and a higher incidence of metabolic consequences.Objectives: To identify the prevalence of metabolic complications in obese children and adolescents.Methods: One thirty-two obese children and adolescents (age...

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...

Objective: To assess the usefulness of the GnRH analogue Diphereline (Triptoreline) in the evaluation of central gonadal dysfunction in children and adults.Methods: A 18-month retrospective study of dynamic testing of the hypothalamic pituitary gonadal axis in 36 patients, 10 prepubescent children (<13 years for girls and 14 years for boys) and 26 postpubescent subjects. The children were investigated for disorders of sexual development while the adu...

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: Ovarian hyperthecosis is a rare cause of severe hyperandrogenism. Unlike PCOS, it is also described in postmenopausal women.We report the case of a 67-year-old obese (BMI=37.5 kg/m2) and dyslipidemic woman, gravid 5 para 3, menopause at 49, with poor controlled type 2 diabetes mellitus (HbA1c=10%). She was in treatment with insulin for the last 12 years, currently on 168 U/24 h (1.71 U/kg)- indicating severe insulin resistance, c...
