Introduction: Pathogenesis of pituitary adenomas is largely unknown thus, identification of genes specific for various types of pituitary tumors should enable better understanding of their biology.The aim of our study was to analyze differences in gene expression between functional (FA) and non-functional (NFA) pituitary adenomas. For this goal, we considered folate receptor (FOLR1) shown by previous study (Evans et al. 2003) to be overexpr...

BackgroundSilent somatotroph pituitary tumours are very rare, representing only 2-4% of all pituitary tumours in surgical series. Little is known about the course of the disease and efficacy of possible treatment modalities.Presentation of the caseA male, born in 1990, was first admitted to the hospital at the age of 15, due to sudden ptosis of the right eye and headaches, present for 1 year before the diagno...

Aim: To investigate T2-signal intensity (SI) and histopathological characteristics of the somatotroph PitNETs (S-PitNET).Methods: 41 out of 109 consecutive patients with newly diagnosed acromegaly and available histopathological results were included. 36 results contained the electron microscope examination. Tumors were divided into 3 SI groups: hyperintensive (HyPER), isointensive (ISO) and hypointensive (HyPO). SI was assessed qualitatively using Visua...

The reference ranges of thyroid function tests during pregnancy are still being debated, even in ethnically homogenous populations. The defining of the normal range is of importance, as it influences therapeutic decisions, particularly the use (or over-use) of levothyroxine in this vulnerable population. The study was aimed at the longitudinal assessment of thyroid function tests results in marginally iodine sufficient Polish population of pregnant women. The study was perform...

Background: Transsphenoidal adenomectomy of GH-secreting pituitary tumour is a first-line treatment of acromegaly. Pharmacological treatment is recommended if surgery did not lead to disease remission. Pathological assessment of postoperative tissue provides clinicians with valuable information on the disease course.Aim: The aim of this study was to assess whether clinical, imaging, and pathological characteristics can predict surgical remission and resp...

Introduction: Reoperation due to recurrent or persistent thyroid cancer (TC) poses a real challenge to a surgeon who must properly estimate the benefit risk-ratio. Radioguided occult lesion localization (ROLL) technique may facilitate the localization and sufficient and safe removal of nonpalpable TC relapse.Aim: To analyze the efficacy of the ROLL technique in reoperation of TC relapse.Material and methods: A retrospective study o...

There are a several known interactions between kidney functions, thyroid and metabolic balance. Hypothyroidism is associated with reduced GFR and hyperthyroidism results in increased GFR and increased RAA activation. Chronic kidney disease is characterized by low T3 syndrome, increased primary hypothyroidism and subclinical hypothyroidism. The hyperthyroidism increases CKD progression while hypothyroid state lowers it. Proteinuria, especially in nephrotic syndrome, often resul...

Introduction: Endocrine disorders can influence the hemostatic balance. Various abnormalities of coagulation-fibrinolytic system have been reported in patients with thyroid dysfunction. The aim of the study was to assess the immunohistochemical expression and distribution of coagulation and fibrinolysis markers in follicular cells of thyroid goiter.Materials and methods: 20 patients with thyroid goiter were included in the study: 11 cases with non-toxic ...

Background: The human leukocyte antigen (HLA) cluster is a genetic region that has been associated with multiple autoimmune disorders, also with autoimmune thyroid diseases. Plenty attempts to establish the significance of class II HLA-DR in Hashimoto’s thyroiditis (HT) development were undertaken in the past; however, reports are rather divergent. This might be caused by different criteria used to diagnose HT. There is however an alternative hypothesis, according to whic...

Diagnosis and treatment of Cushing’s disease is one of the greatest challenges of modern endocrinology. This is related to the fact that pituitary corticotropinomas are small tumours that are difficult to visualize in magnetic resonance imaging (MR). In about 40% of patients with Cushing’s disease, MR scans of the pituitary gland do not reveal any changes. The method that allows to localize the source of adrenocorticotropin (ACTH) secretion is bilateral inferior pe...
