Introduction: Hyperthyroidism is one of frequently encountered clinical syndromes appearing in about 2% of adult population. The aim of this study was to evaluate the efficacy of radioiodine treatment in relation to the form of hyperthyroidism.Material and methods: The study investigated 300 patients: 150 with Graves’ disease and 150 with a toxic adenoma goiter (109 with a solitary nodule and 41 with a multinodular goiter). In all the cases, the est...

Introduction: Acromegaly with normal IGF-1level is rarely diagnosed and is difficult to recognize. In acromegalic pa-tients with poorly controlled diabetes, malnutrition, hepatic injury, hepatic congestion due to heart fail-ure, inflammatory diseases, renal dysfunction, and malignant neoplasm, IGF-1 synthesis is inhibited and thus in such cases normal IGF-1 levels may be observed. The aim of the study is to present a rare case of a patient with acromegaly and normal IGF-1 leve...

Introduction: Visfatin belongs to adipokines, i.e. hormones produced mainly by adipose tissue; its expression and role have been described in many organs, where it regulates energy metabolism, insulin resistance and inflammatory reactions. Moreover, the level of visfatin changes during pregnancy and in obese women and those with obesity related pregnancy pathologies: preeclampsia (PE), gestational diabetes (GDM) or intrauterine growth restriction (IUGR) its level increases. Th...

Introduction: Asprosin, a novel adipokine, is a circulating hormone mainly secreted by white adipose tissue. Asprosin is encoded by the penultimate 2 exons of the fibrillin 1 (FBN1) gene. Protein product of FBN1 is profibrillin-1, which undergoes a proteolytic cleavage by furin enzyme to produce mature fibrillin-1 and asprosin. Literature data indicated that asprosin is involved in the development of diabetes, obesity, cardiomyopathy, cancer, and polycystic o...

Introduction: Atypical pituitary adenomas are often characterized by rapid growth and massive invasion of the surrounding structures. Usually, they are associated with poor prognosis and high recurrence rate due to resistance to conventional therapies. When surgery and radiation are ineffective, alternative therapies remain the last line treatment. Lately, a novel chemotherapy with capecitabine and temozolomide was proposed as a highly effective and extending the life of the p...

Introduction: Adrenal medullary hyperplasia (AMH) is a rare syndrome of catecholamine excess. Adrenal overgrowth is usually bilateral. Due to similar clinical signs, laboratory results and radiological adrenal picture, AMH can be misdiagnosed as pheochromocytoma. The only method that allows determining a proper diagnosis of AMH is pathologic examination. It is regarded as a precursor of pheochromocytoma and has been reported as a component of MEN2.Aim: T...

Introduction: Type 2 amiodarone-induced thyrotoxicosis (AIT2), resulting from the release of thyroid hormones, is a rarer form of side effect of this drug. Treatment of thyrotoxicosis in patients with end stage renal disease (ESRD) is difficult because hemodialysis alters renal clearance of drugs and iodine, may impact the results of assessment and treatment and can increase the medical instability of patients.Aim: The aim was to present the difficulties...

Introduction: Hypopituitarism is characterized by the absence of pituitary hormones. Depending on what pituitary hormones are missing and what is the etiology of hypopituitarism, its clinical manifestation varies. Apart from evident symptoms and signs of hypopituitarism due to hormonal insufficiencies, several studies reveal that long-standing hypopituitarism, including particularly absence of GH, is related to higher risk of metabolic syndrome.Objective...

Introduction: Radioiodine (RAI) has been used for the treatment of Graves’ hyperthyroidism since 1940s. It is relatively safe and considered as one of the definitive therapies. Achievement of hypothyroidism or euthyroidism is defined as a successful therapy.Methods: The study was conducted in 366 patients (80.60% of women) with Graves’ disease (GD), aged 46.76±13.52 years. We analyzed retrospectively hormonal and imaging findings (scintigr...

Introduction: Radioiodine (RAI) is used as a definitive therapy of hyperthyroidism due to toxic adenoma (TA) as well as toxic multinodular goiter (TMG). Achievement of hypothyroidism or euthyroidism is defined as a successful therapy.Methods: The study was conducted in 666 patients – 484 with TA and 182 with TMG (85.58% of women), aged 56.19±13.88 years. We analyzed retrospectively hormonal and imaging findings (scintigraphy, ultrasonography), ...
