Introduction: Multiple Endocrine Neoplasia Type 1 (MEN1) is a rare disease inherited in an autosomal dominant pattern, caused by mutations in the MEN1 gene. The cardinal components of this syndrome are: primary hyperparathyroidism (PHPT), gastroenteropancreatic neuroendocrine tumors (NETs) and pituitary tumors.Aim: The aim of the study was to evaluate clinical features of MEN1 patients under care of two teritiary centers in Warsaw, Poland with special fo...

Introduction: Thyroid diseases are frequent in acromegalic patients. We aimed to investigate thyroid function and morphology in a population of patients with de novo acromegaly.Materials and methods: We evaluated 32 patients newly diagnosed with acromegaly in a single medical center. We collected data on patient’s age, sex, duration of acromegaly symptoms, history of thyroid disease, laboratory tests results (serum GH, IGF1, TSH, fT4, fT3, ...

Background: The curative therapy of primary hyperparathyroidism (pHPT) is surgery. Data about ultrasound-guided laser ablation (LA) of parathyroid tumor are limited, however it could be a solution for patients with high surgery or anesthetic risk. We report our experience on LA of parathyroid tumors in 11 patients with pHPT with high surgery or anesthetic risk.Methods: LA was performed under ultrasound guidance with an output power of 3W. Total energy an...

Background: Multiple Endocrine Neoplasia Type 1 (MEN1) is a rare, autosomal dominant disease characterized by the coexistence of at least two of the following: primary hyperparathyroidism (PHPT), neuroendocrine tumors (NET) and pituitary tumors. The aim of the study was to evaluate epidemiology, clinical features and management of MEN1 patients in two referral centers in Warsaw, Poland.Material and Methods: Study group consisted of 52 patients, aged from...

Introduction: Secondary hyperthyroidism due to thyrotropin-secreting pituitary adenoma (TSHoma) is rare. Coexistence of TSHoma and primary thyroid disease that could lead to hyperthyroidism is even more unusual.Case report: A 28-year-old female with longstanding and worsening symptoms of hyperthyroidism was admitted to the hospital. Free-T4 (32.89 pmol/l) and free-T3 (6.38 pg/ml) were elevated with moderately increased TSH level (5....

Introduction: Ultrasound imagining of parathyroid lesions is often challenging, as they may be difficult to distinguish from thyroid lesions or enlarged lymph nodes.Aim: The aim of the study was to assess the value of parathyroid hormone determination in ultrasound-guided fine-needle aspirates-(FNA) in preoperative localization of parathyroid lesions.Materials and methods: We measured FNA–PTH in 30 consecutive patients with pr...

Introduction: Data regarding the thyroid gland evaluation in Polish adolescents are limited.Aim: The aim of the study was to asses TSH and anti-thyroid peroxidase antibodies (anti-TPO) concentrations as well as thyroid morphology on ultrasound in Warsaw adolescents in regard of family history of thyroid disease.Materials and methods: The study was carried out on a group of 480 adolescents (285 girls and 195 boys), aged 17–18 y...

Introduction: 24-hydroxylase, encoded by a CYP24A1 gene, is a crucial enzyme entailed in catabolism of vitamin D. Loss-of-function mutations of CYP24A1 result in hypercalcemia, not adequately concomitant high levels of 1,25(OH)2D and low PTH levels. The variety of clinical manifestations depends on age – mutations can lead to fatal infantile hypercalcemia among neonates (typically precipitated by supplementation of vitamin D), whereas adults’ symptoms are usually mil...

In the last 18 years 1710 patients with incidentally found adrenal tumours=adrenal incidentalomas (AI), 1300 women (F/M=2.8), aged 10–87 years, were registered at our department. In 338 of them (20%) bilateral tumours were detected. This study aimed at analyzing character of bilateral tumours and defining methods of their management. The size: 1.0–13 cm (in the group of 1710 patients: 1.0–23 cm) most of them up to 3.5 cm. Hormonal and imaging studies were perfor...
