Auscultation of the respiratory system

Abstract: Auscultation of the lung is an important part of the respiratory examination and is helpful in diagnosing various respiratory disorders Auscultation assesses airflow through the trachea-bronchial tree It is important to distinguish normal respiratory sounds from abnormal ones for example crackles, wheezes, and pleural rub in order to make correct diagnosis It is necessary to understand the underlying pathophysiology of various lung sounds generation for better understanding of disease processes Bedside teaching should be strengthened in order to avoid erosion in this age old procedure in the era of technological explosion

COVID-19: a review.

Abstract: The enduring epidemic outbreak which started in Wuhan city of China, in December 2019 caused by the 2019 novel coronavirus (COVID- 19) or the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has created a dangerous and deadly Public Health disaster of International apprehension, with cases confirmed in several countries. This novel community health trouble is frightening the universe with clinical, psychological, emotional, collapse of health system and economical slowdown in each and every part of the world infecting nearly 200 countries. A highly virulent and pathogenic COVID-19 viral infection with incubation period ranging from two to fourteen days, transmitted by breathing of infected droplets or contact with infected droplets, belongs to the genus Coronavirus with its high mutation rate in the Coronaviridae. The likely probable primary reservoir could be bats, because genomic analysis discovered that SARSCoV-2 is phylogenetically interrelated to SARS-like bat viruses. The transitional resource of origin and transfer to humans is not known, however, the rapidly developing pandemic has confirmed human to human transfer. Approximately 1,016,128 reported cases, 211,615 recovered cases and 53,069 deaths of COVID-2019 have been reported to date (April 2, 2020). The symptoms vary from asymptomatic, low grade pyrexia, dry cough, sore throat, breathlessness, tiredness, body aches, fatigue, myalgia, nausea, vomiting, diarrhea, to severe consolidation and pneumonia, acute respiratory distress syndrome (ARDS) and multiple organ dysfunction leading to death with case fatality rate ranging from 2 to 3%.

A Systematic Review of Multisystem Inflammatory Syndrome in Children Associated With SARS-CoV-2 Infection.

Abstract: Background Recently, severe manifestations associated with coronavirus disease 2019 (COVID-19) called multisystem inflammatory syndrome in children (MIS-C) have been recognized. Analysis of studies for this novel syndrome is needed for a better understanding of effective management among affected children. Methods An extensive search strategy was conducted by combining the terms multisystem inflammatory syndrome in children and coronavirus infection or using the term multisystem inflammatory syndrome in children in bibliographic electronic databases (PubMed, EMBASE, and CINAHL) and in preprint servers (BioRxiv.org and MedRxiv.org) following the Preferred Reporting Items for Systematic Reviews and Metaanalyses guidelines to retrieve all articles published from January 1, 2020, to July 31, 2020. Observational cross-sectional, cohort, case series, and case reports were included. Results A total of 328 articles were identified. Sixteen studies with 655 participants (3 months-20 years of age) were included in the final analysis. Most of the children in reported studies presented with fever, gastrointestinal symptoms, and Kawasaki Disease-like symptoms. Sixty-eight percent of the patients required critical care; 40% needed inotropes; 34% received anticoagulation; and 15% required mechanical ventilation. More than two-thirds of the patients received intravenous immunoglobulin and 49% received corticosteroids. Remdesivir and convalescent plasma were the least commonly utilized therapies. Left ventricular dysfunction was reported in 32% of patients. Among patients presenting with KD-like symptoms, 23% developed coronary abnormalities and 26% had circulatory shock. The majority recovered; 11 (1.7%) children died. Conclusions This systematic review delineates and summarizes clinical features, management, and outcomes of MIS-C associated with SARS-CoV-2 infection. Although most children required intensive care and immunomodulatory therapies, favorable outcomes were reported in the majority with low-mortality rates.

Mechanisms of hypoxemia.

Abstract: Oxygen is an essential element for life and without oxygen humans can survive for few minutes only. There should be a balance between oxygen demand and delivery in order to maintain homeostasis within the body. The two main organ systems responsible for oxygen delivery in the body and maintaining homeostasis are respiratory and cardiovascular system. Abnormal function of any of these two would lead to the development of hypoxemia and its detrimental consequences. There are various mechanisms of hypoxemia but ventilation/perfusion mismatch is the most common underlying mechanism of hypoxemia. The present review will focus on definition, various causes, mechanisms, and approach of hypoxemia in human.
