Histiocytosis is a disease caused by growth of histiocytes within one or more organs. Symptomatology may be very different: from isolated skin or bone lesions, by diabetes insipidus after life-threatening multisystem form. Diabetes insipidus as a symptom of pituitary can be observed many years before visibility of the changes in magnetic resonance imaging.A case of 59-year-old woman who has experienced diabetes insipidus with no other symptoms of hypopit...

Introduction: Vitamin D, primarily known for its role in calcium–phosphorus homeostasis, is also a significant immunomodulatory factor. Vitamin D deficiency has been reported in some autoimmune disorders. Recently, vitamin D level in autoimmune thyroiditis (Hashimoto’s thyroiditis (HT)) has become the subject of researchers’ interest.Objectives: This study aims to assess vitamin 25-OH-D3 levels in HT patients in comparison to a control gro...

Introduction: The multimodal management of poorly differentiated thyroid carcinomas (PDTC) and anaplastic carcinomas (ATC) include surgical thyroidectomy, radioiodine treatment, and cytotoxic chemotherapy. Patients with distant metastases which do not respond to radiotherapy could be treated with new therapeutic possibilities like tyrosine kinase inhibitors. PPARγ or mutant P53 are also candidates to PDTC and ATC treatment. Somatostatin and its analogs, demonstrate antipr...

Background: Neck irradiadion is associated with several complications including both hypo- and hyperthyroidism. We present a case of severe hypothyroidism, followed 5 years later by thyrotoxicosis.Case description: A 27-year-old female presented with clinical and biochemical thyrotoxicosis (TSH 0.01 μIU/ml (ref. range: 0.27–4.2 μIU/ml); FreeT4 1.58 ng/dl (ref. 0.98–1.63 ng/dl); FreeT3 4.56 pg/ml (ref. 2.6–4....

Introduction: Primary hyperaldosteronism (PHA) is the most common hormonal cause of secondary hypertensionconnected with substantially higher cardiovascular morbidity and mortality than essential hypertension (EH). The association between aldosterone excess in PHA and mutations in KCNJ5 and CACNA1D genes has been previously described and the possible relation with gene polymorphisms was to consider. The present study is to assess possible association between polymorphisms of i...

Objectives: The objective was to evaluate effects of hyperthyroidism and hypothyroidism on bone metabolism in premenopausal women with special emphasis to osteoprotegerin (OPG) and vitamin D3 (vD).Materials and methods: A total of 119 women aged 18–52 years were studied (38 with recently diagnosed hyperthyroidism; 40 with newly diagnosed hypothyroidism; 41 healthy women as controls). Patients were followed up for a period of 1 year. BMD, ...

Polycystic ovary syndrome (PCOS) is an endocrine disorder with a pathogenesis in which hormonal and metabolic disturbances have been considered. There is evidence of a familial aggregation of hormonal and metabolic abnormalities in siblings of PCOS women. Some of the female relatives fulfill the diagnostic criteria of PCOS. Premature balding in the age of <30 has been proposed as the male phenotype in PCOS families.The aim of the study was to determi...

Recently, low serum adiponectin levels is created as a new risk factor for cardiovascular diseases in climacteric women. Our previous study shows that smoking, serum testosterone levels, blood pressure and BMI have the influence on serum adiponectin levels. Endocannabinoid system plays a role in regulation of food intake and fat accumulation, as well as lipid and carbohydrate metabolism. Menopause transition is related to metabolic disorders (e.g. obesity) and cause the increa...

Background: TSH-suppressive therapy is widely used in treatment of thyroid differentiated carcinoma. A common consequence of therapy is subclinical hyperthyroidism which may cause dysfunction of cardiovascular system, metabolism and reduction of bone mass1. Thyroid hormones are also involved in regulation of brain function2. Therefore, it is not surprising that thyroid dysfunctions are associated with frequent comorbid cognitive dysfunctions and depressio...

Adriamycin (ADR) is a potent chemotherapeutic agent, effective in treatment of leukemias, lymphomas and of many solid tumours. However, its clinical usage is often limited by cardiotoxicity, induced by oxygen radical damage of membrane lipids.Melatonin (MEL), is a well-known antioxidant. It has been shown that melatonin can scavenge free radicals, both directly or indirectly, stimulating the activity of antioxidative enzyme, e.g., glutathione peroxidase ...
