Objective: Conducting comparative analysis of the clinical and laboratory features of the course of community-acquired bacterial pneumonia and pneumonia in the presence of laboratory-confirmed coronavirus infection (COVID-19) in children in Krasnoyarsk.Methods: A retrospective clinical and laboratory analysis of 68 medical histories of children having a laboratory-confirmed diagnosis of a new coronavirus infection (COVID-19) complicated by pneumonia (2020), as well as 52 medical histories of children having community-acquired bacterial pneumonia (2019) is presented.Results: More than half of the cases fall on children older than 7 years. Boys prevailed in both groups. The majority of children in group 1 had a moderate form of COVID-19 course. Cough is the most common symptom in children having bacterial pneumonia. Children having COVID-19 pneumonia had symptoms that were not present in children of group 2: headache – in 19.1% of cases, myalgia – 7.4%, various dyspeptic disorders. In more than 80% of cases of bacterial pneumonia, there were percussion sound dullness and local decreased breath sounds, and more frequent detection of adverse respiratory noises. Changes in the peripheral blood in children with COVID-19 were non-specific.Conclusions: Clinical course of pneumonia in the presence of laboratory-confirmed coronavirus infection (COVID-19) in children has its specific clinical features. The most common symptoms are headache, myalgia, dyspeptic disorders. Children with bacterial pneumonia were more likely to suffer from cough and a strongly marked intoxication syndrome.

Abstract Background Respiratory rate is difficult to measure, especially in neonates who have an irregular breathing pattern. The World Health Organisation recommends a one-minute count, but there is limited data to support this length of observation. We sought to evaluate agreement between the respiratory rate (RR) derived from capnography in neonates, over 15 s, 30 s, 120 s and 300 s, against the recommended 60 s. Methods Neonates at two hospitals in Nairobi were recruited and had capnograph waveforms recorded using the Masimo Rad 97. A single high quality 5 min epoch was randomly chosen from each subject. For each selected epoch, the mean RR was calculated using a breath-detection algorithm applied to the waveform. The RR in the first 60 s was compared to the mean RR measured over the first 15 s, 30 s, 120 s, full 300 s, and last 60 s. We calculated bias and limits of agreement for each comparison and used Bland-Altman plots for visual comparisons. Results A total of 306 capnographs were analysed from individual subjects. The subjects had a median gestation age of 39 weeks with slightly more females (52.3%) than males (47.7%). The majority of the population were term neonates (70.1%) with 39 (12.8%) having a primary respiratory pathology. There was poor agreement between all the comparisons based on the limits of agreement [confidence interval], ranging between 11.9 [− 6.79 to 6.23] breaths per minute in the one versus 2 min comparison, and 34.7 [− 17.59 to 20.53] breaths per minute in the first versus last minute comparison. Worsening agreement was observed in plots with higher RRs. Conclusions Neonates have high variability of RR, even over a short period of time. A slight degradation in the agreement is noted over periods shorter than 1 min. However, this is smaller than observations done 3 min apart in the same subject. Longer periods of observation also reduce agreement. For device developers, precise synchronization is needed when comparing devices to reduce the impact of RR variation. For clinicians, where possible, continuous or repeated monitoring of neonates would be preferable to one time RR measurements.

In the modern world, obesity is the most important medical and social problem that requires an interdisciplinary approach. Many diseases of the respiratory system are caused by obesity.Aim. The review analyzes scientific sources on respiratory disorders in patients with obesity from the open-access electronic libraries PubMed and eLibrary published in the last 15 years.Methods. A comparative systematical assessment of the results of these studies was carried out. The mechanical effects of excess body weight on the respiratory apparatus have been singled out. The current views about cellular and humoral effects of adipose tissue on the development of respiratory pathology have been given.Conclusion. The analysis results present evidence of the multifactorial negative influence of excessive body weight on the respiratory system. Some aspects of the role of obesity in the development of respiratory disorders require further study. Understanding the pathogenic mechanisms behind the influence of obesity on the respiratory apparatus is essential for developing the patient management strategy.

Coronavirus COVID-19 is the cause of severe respiratory pathology and is a dangerous disease, proceeding in various clinical forms with varying degrees severity. This scientific paper presents a literature review of the latest collected data on the course of the novel coronavirus infection COVID-19 and its manifestations in the oral cavity during illness and after convalescence. The transmission routes of the disease and the main symptoms are also described. All healthcare systems in the world have been tasked with prompt diagnosis of coronavirus infection, specialized medical care and rehabilitation. In COVID 19 (SARS-CoV-2), changes in OOM are not the primary cause, but are manifested as a result of drug treatment and disease progression, despite the fact that the oral cavity is one of the sources of entry gate for infection.

Patients with complaints of coughing make up a significant percentage of doctors in various specialties. Cough is not an independent disease, in most clinical cases it is a symptom of a respiratory disease. In acute respiratory pathology, the cough is usually short-lived and stops after the eradication of the infectious agent and the relief of inflammatory changes. It is important therapeutically to provide a reduction in the duration and relief of cough, as well as the prevention of complications. An effective symptomatic agent in the treatment of coughs of various origins, including inflammatory diseases of the respiratory tract, are herbal preparations. The fairly widespread use of phytopreparations in clinical practice is due to their high safety, physiological action, availability and effectiveness. The pharmacological action of these drugs in respiratory infections is manifested by antiinflammatory, cytoprotective, antiviral and antioxidant effects, multifactorial improvement of mucociliary cleansing processes. One of these phytopreparations is a monocomponent syrup with expectorant, mucolytic and antispasmodic. The therapeutic effect of drug is explained by the presence in the composition of triterpene glycosides (saponins) from the leaves of Hedera helix . The effectiveness and safety of drug is proved by a sufficient volume of clinical studies and observations. Literature data show that Hedera helix leaf preparations significantly reduce the severity of acute respiratory infections of the upper respiratory tract.Virtually none of the patients had severe side effects. Allergic reactions were recorded in less than 0.5% of cases, with no mention of a severe allergic reaction of the anaphylaxis type. Thus, the drug of plant origin in the form of drops can be successfully used in patients with symptoms of acute respiratory diseases.

The definition “porcine respiratory disease complex” (PRDC) is used to indicate the current approach for presenting respiratory pathology in modern pig farming. PRDC includes pneumonias with variable pictures, mixed with both aerogenous and hematogenous forms with variable etiology, often multimicrobial, and influenced by environmental and management factors. The notion that many etiological agents of swine respiratory pathology are ubiquitous in the airways is commonly understood; however, their isolation or identification is not always associable with the current pathology. In this complex context, lung lesions registered at slaughterhouse or during necropsy, and supplemented by histological investigations, must be considered as powerful tools for assigning a prominent role to etiologic agents. In recent years, the goal of colocalizing causative agents with the lesions they produce has been frequently applied, and valid examples in routine diagnostics are those that indicate pulmonary involvement during porcine reproductive and respiratory syndrome virus (PRRSV) and porcine circovirus type 2 (PCV2) infections.

Even though COVID-19 is mostly well-known for affecting respiratory pathology, it can also result in several extrapulmonary manifestations, leading to multiorgan damage. A recent reported case of SARS-CoV-2 myocarditis with cardiogenic shock showed a signature of myocardial and kidney ferroptosis, a novel, iron-dependent programmed cell death. The term ferroptosis was coined in the last decade to describe the form of cell death induced by the small molecule erastin. As a specific inducer of ferroptosis, erastin inhibits cystine-glutamate antiporter system Xc-, blocking transportation into the cytoplasm of cystine, a precursor of glutathione (GSH) in exchange with glutamate and the consequent malfunction of GPX4. Ferroptosis is also promoted by intracellular iron overload and by the iron-dependent accumulation of polyunsaturated fatty acids (PUFA)-derived lipid peroxides. Since depletion of GSH, inactivation of GPX4, altered iron metabolism, and upregulation of PUFA peroxidation by reactive oxygen species are peculiar signs of COVID-19, there is the possibility that SARS-CoV-2 may trigger ferroptosis in the cells of multiple organs, thus contributing to multiorgan damage. Here, we review the molecular mechanisms of ferroptosis and its possible relationship with SARS-CoV-2 infection and multiorgan damage. Finally, we analyze the potential interventions that may combat ferroptosis and, therefore, reduce multiorgan damage.

AIM - The onset of COVID-19 pandemic second wave, there have been multiple reports across the country of high incidence of MUCORMYCOSIS among the recovered patients of COVID-19, especially those who are diabetics or those who have received steroids therapy extensively. In this paper, we review about COVID-19 ASSOCIATED MUCORMYCOSIS (CAM) and its management. DISCUSSION - COVID 19 infection may be associated with a wide range of bacterial as well as fungal infections, post- covid. These infections are result of complex interplay of factors such as pre-existing disease such as Diabetes, previous respiratory pathology, use of immune -suppressive therapy. Additionally, the wide spread use of steroids/broad spectrum antibiotics as part of the regimen against COVID-19, may exacerbate the opportunistic fungal infections. COVID-19 ASSOCIATED MUCORMYCOSIS (CAM) has been associated with high morbidity and mortality, resulting in exorbitant treatment cost and also leads to shortage of anti-fungal drugs. RESULT - Successful management of this fatal infection requires early identication of the disease and aggressive and prompt medical and surgical interventions. Therapeutic agents should be used cautiously and closely monitored to achieve desired results.

Statement of Significance Lower respiratory pathologies exhibit a broad spectrum of clinical courses ranging from self-limited to chronic and from benign to fatal. During the present COVID-19 pandemic, the prompt and proper diagnosis of respiratory disease carries even greater importance. Apart from this patient’s presentation with respiratory symptoms during a respiratory pandemic, he demonstrated several concerning features for severe disease including 20 lbs of weight loss and hemoptysis. This teaching case examine the differential diagnosis, workup, clinical considerations, and management of patients presenting with severe respiratory pathology of unknown etiology.
