[Clinical and epidemiological aspects of neuromyelitis optic spectrum diseases in the russian population].

Objective: To present clinical and epidemiological aspects of neuromyelitis optica spectrum disorders (NMOSD) in the Russian Federation.

Material And Methods: We studied 142 patients who met diagnostic criteria of 2015 for NMOSD. Sex, age at disease onset, presence or absence of aquaporin-4 immunoglobulin G antibodies (AQP4-IgG), mail clinical symptoms, oligoclonal IgG, therapy for the treatment of exacerbations and prevention of exacerbations, compliance with 2006 diagnostic criteria were assessed.

[Diagnosis and surgical treatment of mediastinal neoplasms].

The authors share their experiences with examination and surgical treatment of 163 patients with various neoplasms of the mediastinum. The first place among the neoplasms is occupied by tumors of the lymphatic apparatus (33%), the second--by tumors of the thymus (21%). The video-thoracoscopic technique was used in 17 of 131 operations performed.

[The pathophysiological disorders and experimental therapy in pemphigus and pemphigoid].

Guinea pig experiments (n = 196) with simulation of pemphigus vulgaris and bullous pemphigoid helped detect pathophysiologic and metabolic disorders similar for these autoimmune bullous dermatoses: decompensated endoproteinase-inhibitor system, impaired ratio of cyclic nucleotide to arachidonic acid oxigenase metabolism products concentrations in the blood of experimental animals. The key point in the treatment of animals with pemphigus vulgaris was endogenic proteinase inhibition, that in the treatment of bullous pemphigoid--blocking of mononuclear macrophagal histolytic potential.
