PURPOSE. To analyze the relevance of introduction of modern diagnostics methods for the evaluation of drug-related complications that affect the nervous system in TB treatment practice. MATERIALS AND METHODS. We have analyzed the literature data regarding the problem of diagnosing drug-related complications that affect the nervous system in patients with multi-drug resistant pulmonary tuberculosis during the main course of chemotherapy. RESULTS. According to the results of the analysis, it was revealed that today in the TB practice there is over- or under-diagnosing of drug-related complications from the part of nervous system in patients with multi-drug resistant pulmonary tuberculosis during the main course of chemotherapy, which is due to the lack of technical possibilities of control and the need to get conclusions from specialists with narrow expertise – otolaryngologists, ophthalmologists and neuropathologists. CONCLUSIONS. The lack of data on the prevalence of drug-related nervous system complications is due to the possibility of their detection only with the help of specific technical means of control and on the basis of the conclusions of narrow specialists. The wide introduction of electroencephalography using evoked potentials and audiometry in TB practice will allow obtaining objective data on prevalence, carrying out clear differential diagnostics, monitoring the development of such complications, as well as providing timely treatment within the required amount.

One of the most common causes of chronic pain in the facial region, including in the trigeminal nerve link, which is not associated with dental diseases, is pain dysfunction of the temporomandibular joint. At the same time, there is evidence in the literature that there are relationships between pain dysfunction of the temporomandibular joint, abnormal occlusion, cervical-muscular tonic phenomena, postural disorders, dysfunction of the Autonomous nervous system and cochleovestibular manifestations. At the same time, neurophysiological indicators of functional disorders in the maxillofacial region and intersystem interactions in pain dysfunction of the temporomandibular joint are insufficiently studied.Goal. The aim of the work is to evaluate the neurophysiological features of trigeminal afferentation in terms of trigeminal somatosensory evoked potentials (TSWP) and the auditory conducting system of the brain in terms of acoustic stem evoked potentials (ASVP) in distal occlusion of the dentition with pain dysfunction of the temporomandibular joint (TMJ) in comparison with physiological occlusion in students 18-21 years old. Material and methods. The main study included 41 students with distal occlusion (21 girls and 20 boys), (grade II Engl, symmetrically right and left in 14 people, and grade II Engl on the left and grade I on the right in 12 people, grade I on the left and grade II on the right in 15 people). All respondents with distal occlusion and who were practically healthy signed an informed consent to participate in the study. We used complex orthodontic methods of examination, subjective degree of severity and intensity of pain in the TMJ, assessment of the Autonomous nervous system (samples and tests), and neurophysiological methods for assessing TSVP and ASVP. Results. Significant differences in ASEP parameters were found in the group of respondents with distal occlusion in the form of a decrease in the latency period of peak I, III, and V compared to physiological occlusion, that correlated with the subjective assessment (in points) of cochleovestibular disorders. According to the TSVP study, a decrease in the duration of latent periods was found, which indicates an increased excitability of non-specific brain stem structures at the medullo-ponto-mesencephalic level compared to the control group. Conclusions. The results obtained are supposed to be used for differential diagnostics, including such dental diseases as TMJ pain dysfunction, occlusion abnormalities accompanied by pain syndrome. Additional functional diagnostics of multi-modal VP of the brain (acoustic evoked potentials, trigeminal evoked potentials) can be performed in conjunction with indicators of autonomic nervous system dysfunction, with parameters of severity of clinical symptoms of cochleovestibular disorders, musculoskeletal dysfunction the maxillofacial area, with indicators of pain, which will determine the tactics and effectiveness of subsequent treatment.

Introduction. Vibration disease continues to occupy one of the leading places in the structure of professional pathology. In workers after the termination of contact with vibration generalization and progression of violations in an organism is noted. The pathogenetic mechanisms of the progredient course of disturbances in the nervous system in the post-contact period of vibration exposure remain insufficiently studied.The aim of the study was to test an experimental model of vibration exposure to assess the neurophysiological and morphological effects of vibration in rats in the dynamics of the post-contact period.Materials and methods. The work was performed on 168 white male outbred rats aged 3 months weighing 180–260 g. The vibration effect was carried out on a 40 Hz vibrating table for 60 days 5 times a week for 4 hours a day. Examination of animals was performed after the end of the physical factor, on the 30th, 60th and 120th day of the post-contact period. To assess the long-term neurophysiological and morphofunctional effects of vibration in rats, we used indicators of behavioral reactions, bioelectric activity of the somatosensory zone of the cerebral cortex, somatosensory and visual evoked potentials, parameters of muscle response, morphological parameters of nervous tissue.Results. In the dynamics of the post-contact period observed the preservation of violations of tentatively research, motor and emotional components of behavior. In the Central nervous system instability of activity of rhythms of an electroencephalogram, decrease in amplitude of visual evoked potentials, lengthening of latency of somatosensory evoked potentials, decrease in total number of normal neurons and astroglia is established. In the peripheral nervous system remained changes in indicators: increasing duration and latency, reducing the amplitude of the neuromuscular response.Conclusions: The experimental model allows us to study the long-term neurophysiological and morphological effects of vibration on the body. The formation and preservation of changes in behavioral activity, neurophysiological and morphological effects of vibration from the 30th to the 120th day of the post-contact period were confirmed.

The effectiveness in TB treatment is difficult because the structural composition of the mycobacterial cell wall is very complicated, which makes many drugs ineffective. Tuberculosis is still one of the most imperative infectious disease worldwide becouse its important reason is drug resistant, persistent or latent tuberculosis and synergism with HIV. Furthermore no any new chemical entity has come. The recently application of modern drug design promise to bring significant development in the fight against TB. In present review we discussed brief introduction of tuberculosis.

Abstract BACKGROUND High rates of loss to follow-up (LFU) exist among patients with multi-drug and extensively drug-resistant tuberculosis (M/XDR TB); We aimed to identify long-term clinical outcomes of patients who were LFU during second-line TB treatment. METHODS We conducted a follow-up study among adults who received second-line TB treatment in the country of Georgia during 2011-2014 with a final outcome of LFU. We attempted to interview all LFU patients, administered a structured questionnaire and obtained sputum samples. Active TB at follow-up was defined by positive sputum Xpert-TB/RIF or culture. RESULTS Follow-up information was obtained for 461 patients, among these patients, 107 (23%) died and 177 (38%) were contacted, of those contacted 123 (69%) consented to participate and 92 provided sputum samples. Thirteen (14%) had active TB with an estimated infectious time-period for transmitting drug-resistant TB in the community of 480 days (IQR=803). In multivariable analysis, positive culture at the time of LFU was associated with active TB at the time of our study (adjusted risk ratio=13.3, 95% CI: 4.2, 42.2) CONCLUSIONS Nearly one-quarter of patients on second-line TB treatment who were LFU died. Among those LFU evaluated in our study, one in seven remained in the community with positive sputum cultures. To reduce death and transmission of disease, additional strategies are needed to encourage patients to complete treatment.

ObjectiveThis study was designed to identify the risk factors for drug-resistant tuberculosis (DR-TB) and the association between comorbidity and drug resistance among retreated pulmonary tuberculosis (PTB).DesignA retrospective study was conducted among all the 36 monitoring sites in Shandong, China, over a 16-year period. Baseline characteristics were collected from the TB Surveillance System. Categorical variables were compared by Fisher’s exact or Pearson’s χ2 test. The risk factors for drug resistance were identified using univariable analysis and multivariable logistic models. The influence of comorbidity on different types of drug resistance was evaluated by performing multivariable logistic models with the covariates adjusted by age, sex, body mass index, drinking/smoking history and cavity.ResultsA total of 10 975 patients with PTB were recorded during 2004–2019, and of these 1924 retreated PTB were finally included. Among retreated PTB, 26.2% were DR-TB and 12.5% had comorbidity. Smoking (adjusted OR (aOR): 1.69, 95% CI 1.19 to 2.39), cavity (aOR: 1.55, 95% CI 1.22 to 1.97) and comorbidity (aOR: 1.44, 95% CI 1.02 to 2.02) were risk factors for DR-TB. Of 504 DR-TB, 9.5% had diabetes mellitus, followed by hypertension (2.0%) and chronic obstructive pulmonary disease (1.8%). Patients with retreated PTB with comorbidity were more likely to be older, have more bad habits (smoking, alcohol abuse) and have clinical symptoms (expectoration, haemoptysis, weight loss). Comorbidity was significantly associated with DR-TB (aOR: 1.44, 95% CI 1.02 to 2.02), overall rifampin resistance (aOR: 2.17, 95% CI 1.41 to 3.36), overall streptomycin resistance (aOR: 1.51, 95% CI 1.00 to 2.27) and multidrug resistance (aOR: 1.96, 95% CI 1.17 to 3.27) compared with pan-susceptible patients (p<0.05).ConclusionSmoking, cavity and comorbidity lead to an increased risk of drug resistance among retreated PTB. Strategies to improve the host’s health, including smoking cessation, screening and treatment of comorbidity, might contribute to the control of tuberculosis, especially DR-TB, in China.
