Objectives: To evaluate predictors of permanent, transient and three-phase diabetes insipidus (DI) in patients undergoing endoscopic endonasal transsphenoidal surgery.Patients and methods: The study included 154 patients undergoing endoscopic endonasal transsphenoidal surgery (122 women and 32 men) age from 18 to 65 years (median 40 (31;52)). 73 patients with Cushing disease, 66 patients with acromegaly, four patients with prolactinomas, nine patients wi...

Molecular basis of the bone disorders in patients with acromegaly are largely unknown.Objective: To investigate gene expression profiles that regulate bone metabolism in bone tissue samples from patients with acromegaly.Materials and Methods: Patients with clinically evident and biochemically proven active acromegaly and patients with hormonally inactive pituitary adenoma matched by age, sex and BMI were invited to participate. Bon...

Introduction: Regardless of improvements in MRI, up to 20% of ACTH-secreting pituitary tumors are only identified at surgical exploration. The objective was to estimate whether there is any difference in blood vessels and the subsequent ability to uptake contrast agent in visualized micro-adenomas as compared to non-visualized on MRI ACTH-secreting pituitary tumors.Materials and methods: Retrospective evaluation of ACTH-positive pituitary tumors from pat...

Cushing’s disease (CD) remission after primary surgical treatment is achieved in 70–90%, but recurrence ranges 18–25% after.The aim of this work was to study clinical, hormonal and MRI indicators before and after surgical treatment in patients with recurrent CD to identify possible predictors of recurrence. We examined 49 patients with recurrent CD in the active stage (disease duration up to 3 years). Before neurosurgery blood ACTH (median...

Abstract: Transsphenoidal surgery is the treatment of choice for Cushing’s disease. Despite the 70–90% remission rates relapses after successful transnasal adenectomy are frequently observed.Aim: To evaluate the dynamics of intra- and early postoperative levels of adrenocorticotrophic hormone (ACTH) and cortizol and their role as predictors or Cushing’s disease remission.Materials/methods: Fifty patients with Cushing...

Prolactinomas are very rare, but usually more aggressive among children, than in adults. Although treatment strategies for prolactinomas in adults are well established and at present time the preference is given to dopamine agonists, the use of these drugs in pediatric patients is limited due to lack of information on safety and efficiency in this group of patients.A 14-year old boy presented with absent puberty, obesity (weight +4σ) general weaknes...

The aim of said presentation was to direct attention to possibility of misdiagnosis of patients with a giant prolactinomas.A 36 years-old man was admitted to our Centre with complaints of headaches, decline of left eye vision, absence of erection, accompanied with a decline in libido and galactorrhea. These symptoms began since August 2001. At October 2004 reduction of the vision on both eyes was revealed as well as contraction of vision fields. At the p...

Objective: To assess the levels of osmolality, sodium in blood and urine, and copeptin level in patients after transnasal adenomectomy for pituitary adenomas.Materials and methods: A total of 154 patients, aged 18 to 65 years, were included in this study and underwent transnasal adenomectomy. Surgical treatment was performed in 73 patients with Cushing’s disease, 66 – acromegaly, 4 – prolactinoma, 9 – hormonally inact...

ObjectivesTo assess diagnostic and prognostic markers of permanent and transient postoperative diabetes insipidus.Patients and methodsThe study included 152 patients undergone endoscopic endonasal transsphenoidal surgery aged from 18 to 65 years with median 40 [31; 52] years. Seventy three patients had Cushing disease, 66 – acromegaly, 4 – prolactinoma, 9 – hormonally inactive adenoma, 1 –...

IntroductionThyrotropin-secreting pituitary adenomas (TSH-omas) are rare. For this reason each case of TSH-secreting pituitary tumor can help expand extensive clinical experience in world practice.Materials and methodsWe included 40 patients with TSH secreting pituitary adenomas. Hormonal profile: TSH (0.25-3.5 mIU/L), FT4 (9-20 pmol/l) FT3 (2.5-5.5 pmol/l) were measured by Architect i2000SR (Abbott Laborator...
