Radiological manifestations of pulmonary diseases in COVID-19.

[Radiological manifestations of pulmonary diseases in COVID-19]. Radiologe. 2020 Sep 08;: Authors: Heidinger BH, Kifjak D, Prayer F, Beer L, Milos RI, Röhrich S, Arndt H, Prosch H Abstract CLINICAL ISSUE: Since its emergence in late 2019, the disease caused by the novel coronavirus, termed COVID-19, has been declared a pandemic by the World Health Organization. Reference standard for the diagnosis of COVID-19 is a positive reverse transcription polymerase chain reaction (RT-PCR) test. While the RT-PCR shows a high specificity, its sensitivity depends on the duration of symptoms, viral load, quality of the sample, and the assay used. STANDARD RADIOLOGICAL METHODS: Chest radiography and computed tomography (CT) of the chest are the imaging modalities primarily used for assessment of the lung manifestations, extent, and complications of COVID-19 pneumonia. PERFORMANCE: Sensitivity and specificity of chest radiography is low. While sensitivity of CT for detecting COVID-19 pneumonia is high-averaging around 90%-its specificity is low-between 25 and 33%. PRACTICAL RECOMMENDATIONS: Indications for imaging in patients with suspected or diagnosed COVID-19 infection should be carefully considered to minimize the risk of infection for medical personnel and other patients. Imaging, particularly CT, can assess disease extent, complications, and differential diagnoses. COVID-19 pneumonia typically presents with bilateral, subple...

Authors: Yamaya T, Baba T, Hagiwara E, Ikeda S, Niwa T, Kitayama T, Murohashi K, Higa K, Sato Y, Ogura T Abstract Coronavirus disease 2019 (COVID-19) has been recognized as a worldwide pandemic. However, the clinical course of COVID-19 remains poorly characterized. Although some cases of pneumothorax have been reported, they all had pulmonary complications or were managed with mechanical ventilation. We herein report a case of pneumothorax that developed even though the patient had no pulmonary underlying diseases and had never been managed with mechanical ventilation. In the present case, a lung bulla was found on...

Authors: Batista RCS, Arruda CVB, Cassimiro M, Gominho L, Moura AC, Albuquerque DS, Romeiro K Abstract As early as December 2019 in the province of Hubei, China, contamination of patients with pneumonia of an unknown etiology occurred. These patients presented with symptoms such as coughing, sore throat, malaise, diarrhea, high fever, and dyspnea. This emerging disease was named COVID-19 due to being part of the group of coronaviruses (CoVs) belonging to the subfamily Orthocoronavirinae, in the Coronaviridae family and in the Nidovirales order. COVID-19 is most commonly transmitted through speech, coughing, sneezin...

Since the appearance of the novel coronavirus (severe acute respiratory syndrome-coronavirus-2) and related coronavirus disease 2019 (COVID-19) in China in December 2019, a very high number of small and large patient series have been published in literature from around the world. Even though the classical presentation of COVID-19 is one with respiratory symptoms with or without pneumonia that can be self-limiting or evolve into severe respiratory distress syndrome with multiple organ failure, and secondary bacterial sepsis, a large body of evidence suggests a plethora of other types of clinical presentation. In this exhaus...

CONCLUSION: ECMO is a supportive intervention for COVID-19 associated pneumonia that could be considered if the optimum mechanical ventilation is deemed ineffective. Biomarkers such as D-dimer, LDH, and troponin could help with discerning the clinical prognosis in patients with COVID-19 pneumonia. PMID: 33021147 [PubMed - as supplied by publisher]

With each day since U.S. President Donald Trump reported that he tested positive for COVID-19, his doctors have added a new major therapy to treat the disease, for a total of three at this point. On Friday—the same day that Trump said he tested positive—the President received an experimental combination of two monoclonal antibodies to help his immune system fight the coronavirus infection, according to his physician, Sean Conley. The next day—after he was hospitalized at Walter Reed National Military Medical Center—he received the drug remdesivir, which blocks the coronavirus’s ability to make...

Authors: Al-Hwiesh AK, Mohammed AM, Elnokeety M, Al-Hwiesh A, Al-Audah N, Esam S, Abdul-Rahman IS Abstract Coronavirus Disease 2019 (COVID-19) is a pandemic disease that increased the burden on health-care system. In the Kingdom of Saudi Arabia, 74,795 cases have been reported until 26 May 2020 and the number of cases is rapidly increasing. The mortality rate of COVID-19 worldwide is 6.37%. Here we report three cases of acute kidney injury (AKI) secondary to pneumonia of severe COVID-19; they were treated with automated peritoneal dialysis (PD) with full recovery. To the best of our knowledge, few reports in the li...

Novel coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), has rapidly spread throughout the world, resulting in a pandemic with high mortality. There are no effective treatments for the management of severe COVID-19 and current therapeutic trials are focused on antiviral therapy and attenuation of hyper-inflammation with anti-cytokine therapy. Severe COVID-19 pneumonia shares some pathological similarities with severe bacterial pneumonia and sepsis. In particular, it disrupts the haemostatic balance, which results in a procoagulant state locally in the lungs and syst...

Abstract Although COVID-19 is predominantly a respiratory disease, it is known to affect multiple organ systems. In this article, we highlight the impact of SARS-CoV-2 (the coronavirus causing COVID-19) on the central nervous system as there is an urgent need to understand the longitudinal impacts of COVID-19 on brain function, behaviour and cognition. Furthermore, we address the possibility of intergenerational impacts of COVID-19 on the brain, potentially via both maternal and paternal routes. Evidence from preclinical models of earlier coronaviruses has shown direct viral infiltration across the blood-brain bar...

Conclusion. The presence of hypercoagulation status in critical COVID-19 patients should be observed closely, and anticoagulation therapy can be considered in selected patients. More clinical data are needed to examine the role of anticoagulation in COVID-19 treatment. PMID: 32996834 [PubMed - as supplied by publisher]

Conclusions: Standard oral hygiene practice has the potential to contribute to improved oral and general health of children in pediatric ICU. CHX wipes significantly reduced S. aureus count in ventilator patients. Hence, it could be used as an effective antimicrobial agent in pediatric ICU.
