Introduction: Saliva is an interesting alternative to blood in clinical evaluation of endocrine function. Certain advantages of saliva collection must be considered, when comparing with conventional blood sampling. Vital arguments are that procedure is easy, non-invasive and stress-free. The studies on correlation between salivary and serum thyroid hormones are scarce and contradictory. The goal of our research was to assess if salivary thyroid hormone levels reflect serum con...

Introduction: Polycystic ovary syndrome (PCOS) is characterized by menstrual disorders, hyperandrogenism and polycystic ovaries on ultrasonography. This hormonal disorder is also strongly associated with insulin resistance. The diagnosis of PCOS can be established after the exclusion of other causes of mentioned symptoms, such as non-classic congenital adrenal hyperplasia (NCAH). To date, several studies suggest the increased serum concentration of 17-hydroxyprogesterone (17-O...

Introduction: Fine needle aspiration biopsy (FNAB) plays a crucial role in the diagnosis of thyroid nodules. The choice of further therapeutic strategy depends largely on its result. Knowledge of the risk of malignancy in each diagnosis class in the population is necessary. The aim of the research was to analyse the risk of malignancy in thyroid nodules in each diagnosis class according to Bethesda system.Materials and methods: Retrospective research inc...

Introduction: We report a case of CAH who developed several complications due to poor control. Proper diagnosis and treatment can enable men with the disease to have a normal life and fertility. Case report 39-year-old patient with a history of primary adrenal insufficiency was admitted to our department because of infertility. Semen analysis performed prior to hospitalization showed azoospermia. The patient did not have medical documentation regarding his disease and was not ...

A 67-year-old male with PTC (pT3N0) underwent a total thyroidectomy in February 2004. Subsequently he was treated with I-131 and radiotherapy (RT). Combined therapy did not normalize the serum thyroglobulin (TG). Because of elevated TG and persistent I-131 uptake in thyroid bed the patient received a total activity of 21275 MBq of I-131 in 4 years. The treatment was stopped in March 2007 due to a lack of I-131 uptake in the last post-therapeutic whole body scan (WBS) with stil...

Background: The so called “big-big” prolactin, also known as macroprolactin is formed by prolactin-immunoglobulin complexes, and is considered to be biologically inactive. Nevertheless, macroprolactin may cause elevation of serum prolactin (Prl) concentrations measured by standard assays. In women presenting with oligo- and/or amenorrhoea the cause of menstrual irregularity needs to be explained even in the setting of concomitant macroprolactinaemia. We have therefor...

Macroprolactin is formed by prolactin-immunoglobulin complexes and may cause elevation of prolactin (Prl) concentrations, potentially leading to unnecessary investigations and/or treatment. We have endeavoured to assess the prevalence of macroprolactinaemia in euthyroid women with non-toxic goitre and to assess whether autoimmune thyroid disease may result in an increased prevalence of macroprolactinaemia.Material & Methods: We measured serum Prl in ...

Iatrogenic Cushing syndrome caused by the use of steroid medications is common because of the widespread use of these medications for the treatment of many diseases, however development of Cushing syndrome from the topical corticosteroids is very rare in adults.A 45-year-old men (BMI: 44 kg/m2), with a history of psoriasis, developed manifestations of Cushing syndrome, which included weight gain, central obesity, moon face, facial plethora, bu...

Introduction: Prolactin is a hormone which is characterized with a high structural and functional polymorphism. Macroprolactin is one of the form of prolactin - it is a complex of monomeric prolactin and immunoglobulin. Macroprolactin is characterized with immunoreactivity and probably the lack of biological activity.Purpose: The main purpose of our study was to estimate the frequency of macroprolactin appearance among the patients with hyperpronactinaem...

Objective: Hypothyroidism is one of the most common disturbances of thyroid function caused by a thyroid hormone deficiency, found predominantly in young women. The general slowdown of metabolic processes and low-grade chronic inflammatory state occurs in the broad spectra of clinical hypothyroidism manifestations. Although several risk factors of hypothyroidism have been identified, the exact pathogenic mechanisms remain unexplained. The conventional treatment of hypothyroidi...
