Objectives: TSH-producing pituitary adenomas account for 1–2% of all pituitary tumors and there is debate wether transsphenoidal surgery or medical treatment should be recommended as first-line treatment. This study summarizes the authors surgical experience and puts it into context of literature concerning non-surgical treatment of TSHomas.Methods: A retrospective analysis of 12 patients including imaging, laboratory testing, short-term and long-te...

ASA404 (Vadimezan) belongs to a class of agents with disrupting properties against tumor vasculature. Herein, putative therapeutic applicability was investigated in preclinical models for neuroendocrine tumors of the gastroenteropancreatic system (BON) and adrenocortical carcinoma (NCIh295). Upon treatment of tumor bearing mice we detected a significant disruption of microvessels, decrease in cell proliferation, increase of apoptotic cells and extensive necrosis in BON tumors ...

Transsphenoidal surgery is the treatment of choice for acromegaly. Cure is defined by normalization of age-related IGF1 and sufficient suppression of GH in the oral glucose tolerance test (OGTT). We investigated, if early postoperative hormone testing gives reliable information whether complete resection of a tumor was achieved and compared these findings with further follow-up data.So far, 22 patients underwent OGTT within a week after surgery, starting...

Introduction: Postpartum depression affects 10–15% women after childbirth. There is no currently generally accepted theory about the causes and mechanisms of postpartum mental disorders. The principal hypothesis concerns the association with sudden changes in the production of hormones affecting the nervous system of the mother and, on the other hand, with the ability of receptor systems to adapt to these changes.Methods: We observed changes in ster...

Differentiated thyroid cancer (DTC) is a relatively mild disease if detected early.The aim of the study was ultrasound evaluation of thyroid gland, selection of thyroid nodules with high chances of malignancy, and their verification in fine-needle aspiration (FNA), as well as assessment of TSH concentration and antiTPO titre.The study involved 100 patients. DTC was diagnosed in 14 patients and undifferentiated or medullary thyroid ...

Introduction: Acromegaly (ACRO) is a rare disease of an excessive somatic growth and distorted proportions arising from hypersecretion of growth hormone (GH) and insulin-like growth factor-1 (IGF-1). The aim Of this study is to investigate basic demographic parameters such as the age and gender related features, age at diagnosis of the disease, its clinical manifestations, biochemical control and structure of complications in Ukrainian patients with ACRO in a single neuroendoc...

Introduction: Hypothalamic AMP-activated protein kinase (AMPK) has emerged as a key molecular player in energy homeostasis. It participates of glucose homeostasis modulating liver glucose production. It is known that endotoxin shock presents various complicated metabolic aspects. Among them, in later phase circulatory collapse and hypoglycemia are induced with a deterioration of energy metabolism. Here we evaluated the participation of hypothalamic AMPK in the modulation of he...

Introduction: Sterotactic radiosurgery (SR) has been used to treat recurrent adenomas and also as a primary treatment. The objective is to evaluate long-term tumor control, development of hypopituitarism and other side effects in the follow-up.Patients and method: Retrospective analysis of 21 patients with non-functioning pituitary adenomas (NFA) treated with modified linear accelerator (LINAC) between 1998 and 2009 in three tertiary Spanish hospitals. C...

Introduction: Sterotactic radiosurgery (SR) has been used to treat recurrent adenomas after failure of medical and surgical procedures and also as a primary treatment. The aim of this paper is to evaluate long-term control of functioning pituitary adenomas (FPA).Patients and method: Thirty-eight patients with FPA treated with modified linear accelerator (LINAC) between 1998 and 2009 in three tertiary Spanish hospitals. Hormonal control was defined as hor...

Vertebral morphometric X-ray absorptiometry (MXA) is a new tool developed to evaluate the presence of vertebral fractures – main symptoms of osteoporosis. The study aimed at comparing selected morphometric parameters of vertebrae in men and women in various age groups. 965 healthy persons have been involved in the study: 616 female and 349 male, their age ranging from 18 to 79 years. Lateral densitometric scans of the thoracic-lumbar spine were made using Expert-XL densit...
