ABSTRACT
The objective of the present retrospective study was to improve the methods of secondary surgical intervention for the treatment of nasal septum (NS) deformations and evaluate their immediate outcomes. A series of 56 re-operations on NS is represented. Two main approaches to the treatment of secondary deformation were applied: repeated septoplasty with autocartilage and bone re-implantation and tissue-preserving endoscopic submucous resection of deviated septal portions. Endoscopic studies, CT of the nasal cavity and paranasal sinuses, anterior active rhinomanometry, and acoustic rhinometry were used to clarify the character of deformation and to objectively assess the resulting disorders of nasal breathing. The differential approach to the choice of the surgical correction strategy made it possible to restore nasal breathing in all 40 patients followed up during 3 months after re-operation. The results of anterior active rhinomanometry indicate that the mean total volumetric flow increased after the secondary treatment from the initial value of 467.7±89.1cm3/s to 901.1±115.4 cm3/s within the following three months. The cases of postoperative perforation or the development of other possible complications were not documented.

The paper presents the results of electrocardiography, echocardiography, heart rate variability, nonlinear dynamicsin patients with the phenomenon and syndrome of Wolff-Parkinson-White's (WPW). 54 patients whom we divided into 3 groups were included in research: group of patients with WPW a phenomenon, with WPW a syndrome and group of healthy. We proved a role of the main pathophysiological mechanisms in formation of pathology of heart at WPW a syndrome with use of mathematical models. These models are based on the correlation analysis: disturbances of regulatory mechanisms, electric and mechanical remodeling of a myocardium.

A one-year prospective study involved 22 patients with the Wolff-Parkinson-White syndrome (WPW) and 20 healthy people. Means age of patients was 34.3 +/- 16.3 years. All 22 patients were successfully treated with radiofrequency ablation (RFA) of additional pathways. RFA effectiveness was evaluated with the help of clinical questionnaire, data of ECG, EchoCG, heart rate variability (HRV), frequency response and nonlinear dynamics. Cardiac rhythm disturbances were verified using Holter monitoring applied to all patients. Positive clinical effect was achieved in all the WPW patients, as RFA arrested cardiac arrhythmias completely. Holter monitoring did not register cardiac disturbances which points to high RFA effectiveness in WPW patients. HRV, frequency response and nonlinear dynamics reassumed their normal patterns.
