Introduction: Disorder of water and electrolyte balance may develop after transsphenoidal (TNS) surgery for pituitary adenomas. In particular, delayed hyponatremia (Na<135 mEq/l) due to SIADH is reported in 8–35% of patients and usually resolves with fluid-intake restriction within 6 days. The possible role of vasopressin-2 receptor antagonists in this clinical setting has not been elucidated.Case report: We report a case of a 57-years-old Cauca...

Context: Most of the clinical data on safety profile of desmopressin (DDAVP), i.e. an effective treatment of both polyuric conditions and bleeding disorders, originates from studies on tailoring of drug treatment, whereas few reports describe severe side effects secondary to drug–drug interaction.Objective: To describe a case of severe hyponatremia complicated with seizure and coma due to the intake of non steroidal anti-inflammatory drugs (NSAIDs) ...

Patients with craniopharyngioma (CP) are more often operated by transcranial route than patients with nonfunctioning pituitary adenoma (NFPA), have higher prevalence of pituitary deficiencies, are more obese and dyslipidemic and have a higher mortality rate. A previous study in a large group of GHD subjects, showed that the effects of 2-year rhGH replacement are similar in patients operated for CP and in patients operated for NFPA, except for less reduction in fat mass in CP p...

Thyrotropin-secreting pituitary adenomas (TSH-omas) account for less than 1% of all pituitary adenomas. Here we report retrospective data of 17 patients (seven M and 10 F) with TSH-oma followed at our centre from 1990 to present. Median follow-up time was 9.7 years. The mean age at diagnosis was 43±12 years. Radiological evaluation revealed macroadenomas in 11 of 17 patients (71.6%). Macroadenomas were extrasellar in 58.4% of cases, while only one microadenoma had extrase...

Introduction: MEN1 is characterized by tumors of parathyroid glands, pituitary and pancreas. Pituitary tumors frequently produce PRL and GH, but acromegaly due to ectopic GHRH secretion has been reported in <1% of cases. Here we present a case of two patients belonging to a MEN1 family (c.207delC; p.P69PfsX118 mutation (ENST00000377313), affected by primary hyperparathyroidism, in association with acromegaly due to ectopic GHRH secretion and bronchial carcinoid, respective...

Radiation therapy is a useful adjuvant tool for the management of difficult acromegalic patients. Its effects on cardiovascular morbidity are still unknown. Aim of the study was to investigate the long-term effects of radiotherapy on metabolic parameters and cardiovascular risk factors.A total of 42 acromegalic patients (11 M and 31 F, age: 55±12 years, RT group), cured after conventional RT (CRT, n=31) or radiosurgery by gamma-knife (GKRS, <...
