[Condition of hearing sense and tinnitus before and after the treatment of otosclerosis].

Introduction: Otosclerosis is an osteodystrophy disease of the bony labyrinth of the ear which leads to stapes fixation and to bradyecoia of a conductive type. The microsurgical treatment by the use of a stapes prosthesis provides hearing improvement and a reduction or disappearing of tinnitus. The aim of our study was to determine the hearing condition and tinnitus before and after the treatment of otosclerosis.

[Comparative analysis of audiometric and impedancemetric findings in workers exposed to the effects of various duration industrial noise].

Background/aim: Industrial noise is produced in workshops due to factory machinery and tools used in technological processes. It has detrimental effect to primarily the organ of the sense of hearing, thus damaging hearing in oversensitive subjects. The aim of the study was to perform a detailed analysis of audiometric and, especially, impedancemetric parameters in workers exposed to the effects of industrial noise of various duration, as well as to determine similarities and differences in workers with differences in sensitivity to damaging effects of noise.

[The comparative analysis of clinical symptomatology before and after the operation of otosclerosis].

Introduction: Otosclerosis is a progressive osteodystrophic disease of the osseous capsule of the labyrinth which leads to the fixation of the stapes and partial deafness. The progressive hearing loss followed by ear tingling--tinitus and vertigo is of great importance for this disease. The aim of the work was to determine the changes of clinical symptomatology before and after the operative treatment of otoscleoris.

[Effect of hyperbaric oxygen treatment on oxidative stress in patients having diabetes mellitus type 2].

Introduction: The aim of our study was to investigate the influence of breathing oxygen under high pressure on potential prooxidative activity in diabetic patients with serious vascular complications.

Material And Methods: 24 patients with diabetes mellitus type 2, were divided into two groups, 12 patients each, by degree of peripheral vascular complications (by Wagner's scale). The group I was composed of 4 women and 8 men, their average age being 70 years, and average diabetes duration of 12 years, without clinically manifest peripheral vascular complication (Wagner 0).
