Neurological Disabilities

  The relevance of the problem of recurrent respiratory diseases in children with severe neurological pathology is due to the high frequency, severity of clinical symptoms and the protracted nature of their exacerbations, as well as the tendency to chronicity of the pathological process. The aim of the research was to study the respiratory microbiota to optimize antibacterial therapy of recurrent respiratory diseases. Materials and methods: the 16 children with severe neurological pathology at repeated respiratory diseases were examined. We used a microbiological examination of the upper respiratory tract using a deep smear from the oropharynx to identify a possible causative agent of the disease. Research results: the pronounced imbalance of the respiratory microbiota, corresponding to II and III degrees of dysbiotic disorders, was revealed in the examined children. The feature of the microflora of the upper respiratory tract was the dominance of Pseudomonas aeroginosa, intestinal opportunistic microflora (Klebsiella pneumoniae, Proteus vulgaris) and their frequent combination with Streptococcus pyogenus, Staphylococcus aureus and yeast-like mushrooms of the Сandida genus. The maximum degree of respiratory microbiota disorders was noted in the group of children with congenital malformations of the brain and correlated with the severity of bronchopulmonary diseases. The analysis of the pathogenic microflora sensitivity to antibiotics showed high resistance of the identified microorganisms to most medicines. Conclusions: respiratory pathology in children with neurological disabilities is characterized by a recurrent and chronic bronchitis with a tendency of a protracted course which determines the duration of antibiotic therapy. The use of a non-invasive technique for the respiratory microbiota studying makes it possible to identify suspected pathogens of bronchopulmonary diseases and optimize their treatment

COVID-19 manifests itself in a wide spectrum of clinical symptoms, both in terms of their variety and severity. It can be asymptomatic or abortive, mild, moderate, severe and lightning, as septic with multiple organ failure and shock Typical leading symptoms of COVID-19 are: high fever poorly responding to drugs, severe loss of strength, chest pain, dyspnoea, pain headaches, bone and joint pain and muscle pain, until the onset of acute respiratory distress syndrome (ARDS). However, many publications mention among the possible symptoms also others, not related to the involvement of the lower respiratory tract. These are gastrointestinal disorders, damage to the central and peripheral nervous system, catarrh of the upper respiratory tract and dysfunctions of the sensory organs. The aim of this literature review was to determine the frequency of various head and neck dysfunctions that are part of COVID-19. Symptoms of conjunctivitis, nasal mucosa, pharynx and larynx are reported by about of patients, but they do not always occur at the same time, as in infections caused, for example, by rhinoviruses. Anosmi / hyposmia or ageusia / hypogeusia occur with a similar frequency. Symptoms of damage to the equilibrium system, such as dizziness, are reported by approx. 1/3, vertigo and hearing loss approx. 5-6%, tinnitus approx. 10% of patients. Reports of coexistence with COVID-19 of peripheral paresis of the facial nerve are so far relatively few and often included in the neurological disorders, the frequency of which is also about 1/3 of COVID-19 cases. Importantly, both catarrhal symptoms and the others listed here may precede, co-occur or follow the appearance of the leading symptoms of COVID-19. They can also be the only symptoms of this disease. This should prompt otorhinolaryngologists to be particularly vigilant in this regard

Haemophilus parasuis is a common epiphyte of the upper respiratory tract of pigs. The factors of H. parasuis pathogenicity that enable some strains to be virulent and consequently cause a clinical disease have not been established yet. Fifteen serovars of H. parasuis have been described at present. Individual serovars differ in virulence, and considerable differences in virulence also exist within each serovar. Virulent strains can particularly participate as microorganisms secondary to pneumonia, cause septicaemia without polyserositis or Glässer’s disease characterized by polyserositis, pericarditis, arthritis and meningitis. Clinical symptoms of this disease are highly variable. Therefore, culture detection of causative agent, particularly from the brain, joints and polyserositis is an essential diagnostic tool. The disease caused by H. parasuis can be treated with antibiotics; however, oral or parenteral administration of very high doses of antibiotics is necessary. The level of animal hygiene and animal husbandry are important factors for prevention of this disease. Commercial or autogenous vaccines can be used in the immunoprophylaxis of pre-parturient sows and their progeny after weaning. For the production of autogenous vaccines, it is most effective to use isolates from animals with lesions present in CNS. Isolates recovered from arthritic and systemic sites of infection are less suitable and isolates recovered from lungs are not suitable at all because of their heterogeneity.

Ciliary Ultrastructure

The ciliary ultrastructure in transmission electron microscopy and nasal mucociliary transport rate (MTR) by a radioisotopic method were studied in 50 patients with longstanding upper respiratory tract infections. The clinical symptoms correlated well with MTR. The symptoms in patients with MTR 3 mm/min or better were mild, but the patients with poor MTR (less than 3 mm/min) suffered from recurrent or severe infections. The completely normal ultrastructural findings were found only in patients with MTR better than 3 mm/min. All the patients with poor MTR had pathological ciliary ultrastructure, with numerous tubular anomalies and disorientation of ciliary beat direction. The outer dynein arms were found to be short in 16% of cases with poor MTR.

AbstractThe microbiota of the respiratory tract remains a relatively poorly studied subject. At the same time, like the intestinal microbiota, it is involved in modulating the immune response to infectious agents in the host organism. A causal relationship between the composition of the respiratory microbiota and the likelihood of development and the severity of COVID-19 may be hypothesized. We analyze biomaterial from nasopharyngeal smears from 336 patients with a confirmed diagnosis of COVID-19, selected during the first and second waves of the epidemic in Russia. Sequences from a similar study conducted in Spain were also included in the analysis. We investigated associations between disease severity and microbiota at the level of microbial community (community types) and individual microbes (differentially represented species). To search for associations, we performed multivariate analysis, taking into account comorbidities, type of community and lineage of the virus. We found that two out of six community types are associated with a more severe course of the disease, and one of the community types is characterized by high stability (very similar microbiota profiles in different patients) and low level of lung damage. Differential abundance analysis with respect to comorbidities and community type suggested association of Rothia and Streptococcus genera representatives with more severe lung damage, and Leptotrichia, unclassified Lachnospiraceae and Prevotella with milder forms of the disease.

Epiglottic retroversion (ER) is an uncommon and poorly understood disorder of the upper respiratory tract in small breed dogs. In this retrospective study, perioperative characteristics, surgical technique, outcome, and complications in nine dogs that underwent surgical treatment for ER and/or concurrent upper respiratory tract disorders, were evaluated. The most frequently reported clinical symptoms were chronic intermittent inspiratory stridor (89%), exercise intolerance (78%), and dyspnea (67%). Concurrent respiratory disorders were highly prevalent (78%). Five dogs initially underwent a temporary epiglottopexy and two a permanent epiglottopexy. In two dogs, both suffering from concurrent laryngeal paralysis, only a unilateral cricoarytenoid lateralization was performed. After initial clinical improvement, temporary and permanent epiglottopexy eventually failed in 4/6 dogs (67%) that were available for follow-up, necessitating partial epiglottectomy as revision surgery. This resulted in a successful long-term outcome in 5/6 of these dogs (83%). In the dogs with primary ER or in cases where the presence of secondary ER led to significant respiratory symptoms, partial epiglottectomy as a primary surgical technique appeared to be a more permanent treatment option than epiglottopexy. Both dogs with surgically corrected concurrent laryngeal paralysis without epiglottopexy or epiglottectomy showed clinical improvement. This might indicate that, in case of secondary ER, positive results can be achieved after management of the underlying respiratory disorder.

In ostriches, mycoplasmas are generally associated with respiratory diseases and causes rhino-tracheitis, airsacculitis and inflammation of the upper respiratory tract. The aim of current study was the isolation and identification of pathogenic mycoplasmas in ostrich farms of Iran by the use of PCR and culture methods. In this study, mycoplasmas were isolated from ostrich slaughterhouse; 114 samples were collected from ostriches with respiratory signs and were cultured and PCR methods along with alignment were used to detect the mycoplasmas. For this purpose lung, trachea and air sacs were evaluated. The results indicated that 21.05% of samples were positive in PCR assayand from them 7.89% and 14% was M. gallisepticum and M. synoviae, respectively. The highest rate of M. gallisepticum and M. synoviae was detected in lung, airsacs and trachea. Alignment analysis demonstrated that the M. gallisepticum strains detected in our study have 97% homology to 06/14, 05/14 and 16S strains. In addition, M. synoviae strains have 99% and 98% homology to MSR-812, MSR-795 and MSR-1019 strains. One of the M. synoviae strains has 82% homology to ABSfsdMS2011 strain. The results of our study showed that ostriches in Iran were infected with chicken mycoplasmas but the pathogenesis of them in ostrich respiratory should be further evaluated.

The working conditions, occupational and non-occupational risk factors, prevalence rate and peculiarities of the course of respiratory diseases in smelters of titanium alloys were studied. Working conditions of smelters are estimated as harmful (class of working conditions: 3.3-3.4.) due to factors: heating microclimate, chemicals (chlorine and hydrochloride, sulfur dioxide, nitrogen oxide), industrial dust. A feature of the respirable dust fraction is the high content of titanium oxide particles of the PM10 dimension. There was made an analysis of the health status of workers exposed to industrial dust, depending on the length of service. Diseases of the upper respiratory tract in smelters of titanium alloys were shown to be prevalent, simple catarrhal nasopharyngitis prevails with the subsequent formation of atrophic rhinitis, its prevalence rate among smelters of titanium alloys increases with the experience. The peculiarity of the development of diseases of the upper respiratory tract in smelters of titanium alloys are: deterioration of nasal breathing in workers with experience of from 1 year to 5 years already, in patients with experience from 10 to 15 years the prevalence of catarrhal nasopharyngitis and atrophic rhinitis as its outcome in cases with experience from 15 to 20 years. The bronchial damage in the smelters of titanium alloys develops under the experience more than 5 years. The clinical forms are dominated by the phenomena of catarrhal bronchitis followed by obstruction of the bronchi progressing with the experience, with the formation of irreversible ventilation disorders. With the depletion of antioxidant protection, as a rule, with long duration of the exposure of up to 10 years, aseptic inflammation is formed, which is pronounced clinically as catarrhal endobronchitis. This is a partially reversible pathological process. The described features of the development and course of respiratory diseases in smelters of titanium alloys should be taken into account during periodic medical examinations in order to timely prevent them

Mycoplasma Ovipneumoniae

Mycoplasma ovipneumoniae (M. ovipneumoniae) is a respiratory pathogen associated with the development of mild to moderate respiratory disease in domestic lambs and severe pneumonia outbreaks in wild ruminants such as bighorn sheep. However, whether M. ovipneumoniae by itself causes clinical respiratory disease in domestic sheep in the absence of secondary bacterial pathogens is still a matter of debate. The goal of our study was to better understand the role of M. ovipneumoniae as a respiratory pathogen in domestic sheep and to explore potential antibiotic treatment approaches. Therefore, we inoculated four-month-old, specific-pathogen-free lambs with field isolates of M. ovipneumoniae and monitored the lambs for eight weeks for colonization with the bacteria, M. ovipneumoniae-specific antibodies, clinical symptoms, and cellular and molecular correlates of lung inflammation. After eight weeks, lambs were treated with the macrolide antibiotic gamithromycin and observed for an additional four weeks. Stable colonization of the upper respiratory tract with M. ovipneumoniae was established in all four M. ovipneumoniae-inoculated, but in none of the four mock-infected lambs. All M. ovipneumoniae-infected lambs developed a robust antibody response to M. ovipneumoniae within 2 weeks. However, we did not observe significant clinical symptoms or evidence of lung damage or inflammation in any of the infected lambs. Interestingly, treatment with gamithromycin failed to reduce M. ovipneumoniae colonization. These observations indicate that, in the absence of co-factors, M. ovipneumoniae causes asymptomatic colonization of the upper respiratory tract of that is resistant to clearance by the host immune response as well as by gamithromycin treatment in domestic lambs.

Conditions Of Learning

Introduction. It is relevant to determine periods of adaptation of local and non-resident students coming from other Russian regions to learning conditions. The objective of our study was to measure duration of cadets’ adaptation to the learning environment as assessed by the incidence of respiratory diseases in view of synergistic effects of health risk factors in the Kaliningrad enclave. Materials and methods. We conducted a retrospective analysis of the incidence of respiratory diseases in cadets of two military universities (n = 3,381, n = 2,013) by cohorts (local and non-resident students) for five academic years in general and by year. Results. The proportion of respiratory diseases in university cadets was as high as 70.9 ± 2.0 and 52.1 ± 1.1 % in Universities 1 and 2, respectively. The share of respiratory diseases in the first and fifth-year students was 72.3 and 59.9 % in University 1,and 60.3 and 38.1 % in University 2, respectively. The respiratory disease incidence in non-resident cadets was 1.8 and 1.2 times higher than that in locals: 1,102.6 ± 6.2 versus 617.7 ± 24.5 ‰ and 477.6 ± 14.1 versus 388.2 ± 16.1 ‰ (p = 0.001) in Universities 1 and 2, respectively. We found differences in the rates of acute sinusitis, acute tonsillitis, upper respiratory tract infections and influenza, community-acquired pneumonia, and lower respiratory tract infections between local and non-resident cadets. In the second university, differences in the incidence of acute sinusitis and upper respiratory tract infections were still observed in third-year students while in the first university they were still pronounced in cadets during the fourth year of study. We suppose that they might be attributed to learning conditions, ratios of local to non-resident cadets, differences in living conditions and nutrition between the students. Conclusion. Duration of the period of adaptation of military university cadets to conditions of learning is influenced by a synergistic effect of adverse environmental factors. Adaptation of non-resident cadets lasts longer due to acclimatization to weather and climate conditions of the enclave. The incidence of respiratory diseases proves the differences in learning conditions between the universities.
