This work is based on the results of clinical and functional studies of the cardiovascular and respiratory systems in adolescents with ADS, depending on the presence of perinatal pathology. In order to identify the features of the state of the respiratory system and cardiac activity in children with autonomic dysfunctions, depending on gender. We examined 243 adolescents 12-18 years old with clinically and laboratory-instrumental confirmed dysfunction of the autonomic nervous system - autonomic dystonia syndrome. It was found that signs of cardiac dysfunction are more often observed in adolescents with ADS with a history of perinatal pathology, mostly in males. The risk of developing violations of bronchial patency was identified in adolescents with ADS with a history of perinatal pathology, to a greater extent in females.

This work is based on the results of a study of the assessment of physical parameters of the electroencephalogram in adolescents with autonomic dysfunction, depending on gender and the presence of perinatal pathology in the anamnesis. We examined 87 adolescents 12-18 years old with clinically and laboratory-instrumental confirmed dysfunction of the autonomic nervous system -autonomic dystonia syndrome (ADS). The average age of the clinical manifestation of ADS in girls was 12.2 ± 1.8 years, in boys -13.5 ± 2.1 years. As a result of the study, it was revealed that adolescents with a history of perinatal pathology have the maximum risk of disturbances in the processes of myocardial repolarization at the end of the recovery period after physical exertion, especially in females

Several independent pathological studies in experimental models and in human beings showed conspicuous autonomic denervation in Chagas' disease. In spite of the inherently complex structural organization of the autonomic nervous system, the parasympathetic and sympathetic divisions are involved, as shown by many functional studies. Hence, Chagas' disease represents a unique model of impairment of the autonomic control of the heart, in absence of the nonspecific effects of cardiac failure. An important limitation of the studies thus far carried out is the lack of a better knowledge of the molecular biology characteristics of different strains of T. cruzi. This could explain some geographical discrepancies found in the clinical behaviour of Chagas' disease, and contribute to a better understanding of its pathophysiology.

AbstractBackground: In the past two decades, there has been increasing evidence to suggest that trigeminal neuralgia (TN) may be linked to a dysfunction of the autonomic nervous system (ANS). The aim of the present study was to formally test this hypothesis by comparing the reactivity of the ANS to experimental pain in a population of TN patients and healthy controls. Methods: Twelve patients diagnosed with classical TN and 12 healthy controls participated in the study. Cardiac activity was assessed while participants were instructed to rest and again during a cold pressor test (CPT). Heart rate variability analyses were performed off-line to obtain parasympathetic (high-frequency) and sympathetic (low-frequency) indices. Results: At baseline, ANS measures did not differ between healthy controls and TN patients, and both groups showed a similar increase in heart rate during the CPT (all p values >0.05). However, TN patients showed a greater increase in cardiac sympathetic activity and a greater decrease in cardiac parasympathetic activity during CPT compared with healthy controls (all p values <0.05). Importantly, changes in sympathetic reactivity, from baseline to CPT, were negatively associated with the number of pain paroxysms experienced each day by TN patients in the preceding week (r=−.58, p<0.05). Conclusions: These results suggest that TN, like many other short-lasting, unilateral facial pain conditions, is linked to ANS alterations. Future studies are required to determine if the altered ANS response observed in TN patients is a cause or a consequence of TN pain

Abstract Background: Frequent cessations of respiration can greatly increase the prevalence rate of arrhythmia. It has been confirmed that cardiac activity is regulated by autonomic nervous system (ANS). And heart rate variability (HRV) is widely used as a method to evaluate the function of ANS. Therefore, we analyzed whether apnea can affect the balance and normal function of ANS using short-term HRV indices. Methods: Forty-five healthy subjects were asked to breathe normally and hold their breathing to simulate 10 times apnea. Thirty-six patients from the dataset of a sleep laboratory for the diagnosis of sleep disorders with 10 times apnea were included in analysis. We calculated short-term HRV indices of subjects in normal respiratory and apneic states, respectively. Results: Compared with normal respiratory state, respiration cease would lead to the values of the mean-RR, nLF, LF/HF, and α1 were significantly increase whereas the values of rMSSD and nHF were significantly decrease. Conclusions: Cessations of respiration would lead to an imbalance in function of ANS, as well as an increase in fractal characteristics of the heart. These changes in physiological state are likely to induce and cause the occurrence of arrhythmia, which is regulated by ANS.

Differentia! diagnosis of the causes of prolonged cough is difficult because of its multifactorial nature. Diagnostics in case of a cough that persists for more than 4 weeks is based on clinical data, but sometimes it is not enough to establish a diagnosis. This issue led to the development of algorithms based on additional diagnostic criteria evaluated with modern non-invasive functional methods for diagnosing diseases accompanied by a prolonged cough in children.Aim. To determine the differential diagnostic value of the functional parameters of the capillary bed, respiratory tract, and autonomic nervous system in children with diseases accompanied by a prolonged cough (more than 4 weeks).Methods. 238 children aged from 2 to 17 years with prolonged cough were examined in inpatient or outpatient settings and divided into 4 groups: Group 1 (n = 68) - patients with acute or exacerbation of the chronic infectious upper respiratory tract diseases; Group 2 (n = 53) - patients with lower respiratory tract infection; Group 3 (n = 39) - patients with allergic rhinitis; Group 4 (n = 78) - patients with bronchial asthma. All patients underwent standard clinical examination. The diagnostic test also included functional assessment of microcirculation, autonomic nervous system, and respiratory system via computer capillaroscopy of the nail bed, evaluation of heart rate variability, and computer bronchophonography.Results. Patients with allergic diseases of the respiratory tract, especially with asthma, show a change in all parts of the capillary bed and a significant increase in the zone of perivascular edema in combination with parasympathicotonia, in contrast to children with infectious diseases of the respiratory system, who showed a change in microcirculation parameters mainly in the venous capillaries in combination with sympathicotonia. In addition, children with prolonged coughing, regardless of its origin, showed functional changes in the high-frequency acoustic parameters of the respiratory system in the form of an increase in the coefficient of the high-frequency acoustic component of breathing (ф3), which indicates bronchial hyperreactivity.Conclusion. The functional parameters of the microvasculature, autonomic nervous system, and respiratory tract can be used as additional differential diagnostic criteria and included in algorithms for diagnosing respiratory diseases of various origins in childhood, contributing to the early detection of the pathology and timely targeted therapy.

An exploration of 110 healthy men (not involved in sports and athletes) with the use of hypoxic loads was carried out. It is established that the specifics of the regulation of gas exchange depend on the nature of training loads (aerobic or mixed), which are manifested in the parameters of chemoreflector reactivity, the pattern of external respiration, gas exchange and activity of the autonomic nervous system under hypoxic load. As sports qualifications grow, the mechanisms of intersystem integration of the functions of the cardio-respiratory system are improved, which is manifested in an increase in cardiorespiratory coherence. Key words: athletes, hypoxia, cardiorespiratory system, gas exchange of the body, chemoreceptor reactivity.
