Introduction: Subclinical hyperthyreosis (SH) affects about 1.5% population at least. The diagnosis of this disease leans on the laboratory criteria only: decreased of TSH and normal FT3 and FT4 levels. SH increases mortality and there is no unequivocal procedure algorithm to manage patients with this desease.Aim: To estimate an influence of cure of SH on heart rate and on autonomous nervous sytem and to find the relationships between parameters of Holte...

Background: Primary hyperparathyroidism (HPT) is the most common endocrinopathy in MEN1 and usually its first clinical manifestation. Yet MEN1 is a rare disease, representing only 2–4% of all cases of HTP. We studied the frequency of MEN1 syndrome in HPT patients admitted to our Department.Methods: In a retrospective analysis of 84 suspected HPT patients hospitalized in 1999–2006, case reports of 11 patients with suspected MEN1 were analysed. M...

Introduction: The molecular events involved in the formation of parathyroid adenomas are not well understood. Two genes, cyclin D1 (CCND1) and MEN-1, have been established as having major roles in parathyroid tumorigenesis. Tumor suppressor gene HRPT2 is frequently mutated in parathyroid carcinoma. The aim of our study was to analyze HRPT2 expression in parathyroid adenomas and in residual normal/atrophic parathyroid tissue and to relate it to other...

Introduction: Only several cases of co-existing meningiomas and pituitary tumours secreting growth hormone (GH) have been described so far in patients not treated previously with irradiation.Aim: The aim of the study was to describe two cases of co-occurrence of acromegaly and meningioma and to discuss their relationship.Case reports: Case 1. 52-year old female complained of visual disturbances. She was diagnosed with pituitary mic...

Background: Primary hyperparathyroidism is one of the most common endocrine disorders caused by adenoma (80%), hyperplasia (15%) and carcinoma (5%). It is often difficult to differentiate between hyperplasia from an adenoma of a parathyroid gland. Toll/interleukin-1 receptor (TIR)-associated protein (TIRAP) is an adaptor protein for Toll-like receptors-2 and -4 (TLR2/4) which are engaged in transducing the signal to downstream molecules. Several studies have shown the increase...

Background: Even if a great number of studies have been developed recently, the molecular mechanisms of pathogenesis of hyperplastic lesions of the parathyroid glands are not well understood. The link between systemic inflammation and promotion of neoplasm is well established. Chronic infection and inflammation are considered two of the most prominent epigenetic and environmental factors contributing to tumor formation. Toll like receptors (TLRs) are essential components of in...

We present extremely rare case of a female patient with the coincidence of hyperthyroidism, exophthalmos and Erdheim–Chester disease (a rare form of non-Langerhans cell histiocytosis, positive BRAF mutation). The patient was hospitalized due to exacerbations of the primary disease and symptoms of thyroid dysfunction. For about two months, the patient has reported increased feeling of heat, sweating, palpitations, weight loss of about 10 kg for 3 months, significant intens...

Objectives: Endogenous Cushing’s syndrome (CS) is a rare, chronic condition that results in high morbidity, caused by prolonged exposure to elevated levels of circulating free cortisol. A previous comparative analysis showed osilodrostat increases the odds of complete response (CR; mean urinary free cortisol [mUFC] ≤ 1.0 x the upper limit of normal) at Weeks 12 and 36 vs metyrapone1; however, analyses were limited by small osilodrostat effective sample si...

Background: The impact of subclinical hyperthyroidism (sHT) on lipids concentration is still unclear. The aim of the study was to prospectively evaluate the changes in lipid profile in patients with sHT and following restoration of euthyroid state.Patients and methods: The studied group consisted of 44 patients (37 females, 7 males), diagnosed with endogenous sHT in the course of either toxic multinodular goiter, diffused thyroid autonomy or autonomously...

Background: Turner syndrome (TS) is the most common chromosome deficiency in women, with an incidence of 1 in 2 000 female newborns. Acromegaly is a rare disease, which occurs with a frequency of 1:140 000–250 000 of the population. To our knowledge only several cases of TS and acromegaly coexistance have been reported up to date.Case presentation: A 43-year-old woman with TS was referred to our Department with an accidentally discovered pituitary m...
