Background: During pregnancy, the physiology of the thyroid gland undergoes important changes. As a result, change levels of thyroid hormones. In the latest clinical guidelines, experts have recommended to perform population-based studies to determine reference intervals for thyroid hormones.Aim: To evaluate the reference intervals of free thyroxine in different trimesters of pregnancy in women living in regions with mild iodine deficiency.<p class="...

Introduction: One of the manifestations of Munchausen syndrome is the deliberate injection of insulin to achieve hypoglycemia or artificial hypoglycemia. If human insulin is injected, we will always determine high level of insulin and low level of Cpeptideatthemomentofhypoglycemia. Incasesof insulin analogues injection the diagnos is maybe difficult when we use analyzers specific only to human insulin: the low level of IRI and C peptide will be determined.<p class="abstext...

Introduction: One of the autoimmunenon-diabetic hypoglycemia (NDH) causes isthe antibodies to insulinreceptor (AB-rIRI) formation and/orinsulin resistance type B (TBIR).Objectives: To determine the prevalence of increased AB-rIRI level in patients with suspected NDH of different genesis and in healthy individuals; to determine significance of AB-rIRI investigation in NDH diagnosis.Methods: In a prospective study we determined AB-rI...

Introduction: Hyponatremia after transnasal neurosurgery for pituitary adenomas is a serious and not so rare complication. It often occurs in a delayed manner after patient’s discharge and is a major cause of readmission. The pathogenesis of postneurosurgical hyponatremia is not clear yet.Aims: To study the role of posterior pituitary hormones (antidiuretic hormone (ADH) and apelin) and reaction of renin-aldosterone system (RAS) at hyponatremia mani...

Backgraund: The high incidence of cervical lymph nodes (LNs) metastasis in differentiated thyroid carcinoma (DTC) and lack of effective diagnostic tools determines the need for elaboration more specific tests.Aims: The aim of our study was to evaluate the accuracy and cut-off point of the thyroglobulin (Tg) in the washout fluid of fine-needle aspiration biopsy (FNA-Tg) in the diagnosis of DTC LNs metastasis.Materials and methods: A...
