Simple, reliable and predictable obturation of root canals side by side with their cleaning and forming is an essential part of the endodontic treatment. The aim of this research is investigation of obturation density of root canals. Canals filled by means of lateral condensation of the new obturative system «Real Seal/Resilon» and by means of traditional method of canals obturation with the help of gutta-percha and sealer АН-plus. The results of the research proved a ligher hermetizing ability of the new experimental material «Real Seal» in comparison with obturation by means of gutta-percha pins. The obtained data reflects an objective picture and can be applied as a unique quality monitoring obturation of root canals.

Research objective is to reveal functional changes of masticatory muscles in patients with fractures of lower jaw in combination with dentition abnormalities. Materials. 72 patients with such pathology have been examined. As a result of clinico-laboratory methods of research functional disturbances of masticatory muscles and their changes during the course of surgical and orthopaedic treatment have been revealed. It has been established that restoration of amplitude of biopotentials of masticatory muscles is possible at easy stage of musculo-articular dysfunction. Conclusion. At average and severe stages of dysfunction normal parameters may be reached.

Processes of urbanization, stressful events and other social trends of the modern world are considered as the social predictors determining the growth of frequency of mental illness. They are directly associated with manifestations of mental disorders, including schizophrenia. The majority of people is subjected to mental disorders living in unfavorable conditions. According to severe social consequences schizophrenia takes the leading position in psychiatry. Course of schizophrenia is one of the main clinical predictors of clinical and social prognosis. The research has established that the clinical predictors determining the severity of non-cancerous condition of patients with schizophrenia are not obligate in the socialization of the patients.

The research goal of the study was to assess frequency of allergic rhinitis diagnostics in schoolchildren with bronchial asthma and to evaluate treatment approaches to combined allergic pathology of respiratory tract in clinical practice. Materials: Retrospective analysis of medical records of all asthmatic schoolchildren in-patients admitted in 2003-2010 has been performed. 240 patients have been included in the study. Results: 61.7% schoolchildren had symptoms suspicious of allergic rhinitis. Nevertheless, the diagnosis of allergic rhinitis was established only in 56 patients (23.3%). Obviously, children with allergic rhinitis or nasal symptoms had more severe clinical course of asthma. The latter required significantly more frequent and intensive use of prolonged broncholytics in order to enhance the anti-inflammatory treatment (inhalation corticosteroids) (p < 0.05). Conclusion: in schoolchildren with bronchial asthma allergic rhinitis is diagnosed inadequately (insufficiently). This fact does not allow to start treatment intime and ipso facto to improve the clinical course of bronchial asthma.

The article presents a historical overview of different measurement methods of mobility of middle ear structures. It points out a thorough research of transition from mechanical measurement techniques with mathematical approximation to the nanotechnological methods. The main approaches to modern mathematical models of middle ear construction including finite element method have been described in the work.

The aim of the study was to analyze epidemiological and demographic characteristics of patients with myasthenia gravis in the Samara region. Material and methods. Data of electronic register of Regional myasthenic center containing information about 340 patients were used. Prevalence of myasthenia gravis in area made up 9,7; average annual disease over the last 10 years — 0,73 per 100000. Results. The data obtained are comparable with the global characteristics of the disease, but higher than the figures of some domestic researches. Conclusion. Confirms the fact that in regions where work specialized myasthenic centers, epidemiological parameters are always higher.

Data of diagnostics of cerebrovascular disorders in craniovertebral passage due to Arnold — Kiary anomaly I have been considered. Clinical picture of the disease in different age groups has been represented. Condition of extra- and intracranial part of vertebral arteries and venous plexuses of the cervical part of vertebral column and craniovertebral passage, pathological asymmetry of the blood flow have been estimated. Efficacy of conservative and surgical treatment has been compared.

Treatment alcoholic polyneuropathy is one of the most important challenges of health care not only in Russia, but throughout the world. Material and methods. A comparison study of efficacy and tolerability ofthefarmacopuncture in 58 patients with alcoholic polyneuropathy [36 (62,1%) male, 22 (37,9%) female, mean age 41,5±12,4 years]. Introduction of thiamin (vitamin B1) in BAP of the cohort studied was accompanied by a positive dynamics of both subjective and objective clinical symptoms. By means of standard ENMG methods the study was made of motor fibrae of median, tibia, fibular and sensory fibrae of median nerves. Results. Farmacopuncture is tolerable and safe. Conclusions. The results of the study confirm an assumption of introduction of thiamin in БАТ efficacy in alcoholic polyneuropathy and allow to recommend the drug for a wide clinical application.

Purpose. The study of the influence of extracorporeal and intravascular hemocorrection methods (plasmapheresis, ultraviolet blood radiation, ozonetherapy and its combination) on skin process and life quality in patients with extensive psoriasis. Methods. 253 patients with extensive psoriasis from the age of 18 to 72 have been investigated. PASI (Psoriasis Area and Severity Index) and dermatological index of life quality (DILQ) have been used for treatment assessment. Results. The inclusion of efferent quantum and ozone therapy methods in the complex treatment of psoriasis has promoted to the more rapid and complete positive dynamics of skin process and the improvement of life quality. The use of plasmapheresis and its variations with photomodification or the ozone treatment of returning erythrocyte suspension has been the most effective. Plasmapheresis and its modifications are appropriateto be used in the complex treatment of the patients with severe forms of psoriasis. Conclusion: Further study of efferent quantum and ozone therapy methods and their wider use in psoriasis therapy and other chronic dermatosis seem to be promising.

Nowadays paroxysmal AV nodal reentrant tachycardia (AVNRT) is one of the most widespread arrhythmias. In most cases AVRNT is a recurrent process, and it worsens the life quality of such patients, reduces their workability and increases the incidence of applying for medical help. Thus AVNRT today is of special attention among investigators. The interest of clinicians to the problem of cardiac arrhythmias is associated with permanent dissatisfaction with the results of antiarrhythmic therapy and also with the rapid development of the surgical methods of treatment, i.e. the use of radio frequency catheter ablation.
