A link between promoter polymorphisms of the transforming growth factor β1 (TGFB1) and TGF-β1 receptor II (TGFBR2) genes and relapsing-remitting multiple sclerosis.

Introduction: Multiple sclerosis (MS) is a chronic progressive autoimmune disease characterised by nerve demyelination, mediated by myelin-specific Th1 autoreactive cells. Transforming growth factor 1 (TGF-1) is a regulatory cytokine involved in MS aetiology by maintaining CD4+ cell differentiation and preventing autoimmune responses. Because of the important role of the TGF-1 signalling pathway in MS aetiopathogenesis, we aimed to investigate the association of two DNA polymorphisms: TGFB1C[-509]T and TGFBR2G[-875]A and their combined genotypes with the risk of MS development in a cohort of Bulgarian patients.

Serum Iron Metabolism Variables in Clinically Healthy Persons.

Background: In healthy persons, iron acquisition, trafficking and storage are strictly regulated processes due to the lack of a physiological pathway for the excretion of excess iron from the body. The liver, the duodenum and the bone marrow are involved in the regulation of iron metabolism.

Material: Subject to the testing were 60 healthy volunteers who took part in clinical trials.

A Rare Case of Dermatofibrosarcoma Protuberans of the Thumb in an 80-year-old Woman.

Dermatofibrosarcoma protuberans (DFSP) has been described as a rare, locally invasive, malignant fibroblastic tumor with a high rate of recurrence that usually affects middle-aged patients. Herein, we describe a rare case of a pedunculated dermatofibrosarcoma protuberans of the right thumb in an 80-year-old woman treated with excision through the base of the pedicle. We also make a brief literature review concerning this tumor.

[Vaginal sonography as a method for examination of women with pre- and postmenopausal bleeding].

At present time abrasio probatoria of the cavum uteri is a method of choice in diagnostic of the endometrial pathology.
