Efficient GAN-based Chest Radiographs (CXR) augmentation to diagnose coronavirus disease pneumonia.

Conclusion: If the gap in identifying of all viral pneumonias is not filled with effective automation of chest disease detection the healthcare industry may have to bear unfavorable circumstances. PMID: 32624700 [PubMed - in process]

This study aimed to compare clinical features in adult patients with coronavirus disease 2019 (COVID-19) pneumonia to those in adult patients with community-acquired pneumonia (CAP).Methods: Clinical presentations, laboratory findings, imaging features, complications, treatment and outcomes were compared between patients with COVID-19 pneumonia and patients with CAP. The study group of patients with COVID-19 pneumonia consisted of 120 patients. One hundred and thirty-four patients with CAP were enrolled for comparison.Results: Patients with COVID-19 pneumonia had lower levels of abnormal laboratory parameters [white blood ...

Conclusion: Development of pneumonia delayed viral clearance in mild COVID-19 patients. Patients with older age or diarrhea may need to be closely monitored, given the increased risk of pneumonia. PMID: 32972121 [PubMed - as supplied by publisher]

We report three patients with history of fever and different clinical signs. During the height of the pandemic in Italy (March to May 2020), these patients underwent chest computed tomography (CT) scans that showed lung alterations typical of COVID-19 with multiple negative RT-PCR tests and positive serology for SARS-CoV-2.

h 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...

CONCLUSIONS: We recommend extreme caution in using CP in critically ill patients more than 2 weeks after the onset of COVID-19 pneumonia. PMID: 32770691 [PubMed - as supplied by publisher]

ConclusionIt seems unnecessary to perform chest imaging in children to diagnose COVID-19. Chest radiography can be used in symptomatic children to assess airway infection or pneumonia. CT should be reserved for when there is clinical concern to assess for possible complications, especially in children with coexisting medical conditions.

Coronavirus Disease 2019 (COVID-19) has caused a large number of related deaths and multiple healthcare associated outbreaks [1,2,3,4]. Investigators have summarized the clinical characteristics of patients with initial onset [3,4], in which, some had atypical clinical manifestations, e.g., severe patients merely had moderate or low fever or even no fever [5], while some mild patients may not have pneumonia and only had low fever or mild fatigue [5,6]. One report revealed that no radiographic or CT abnormalities were found in 17.9% of non-severe patients and in 2.9% of severe patients [6].

Conclusions: On the whole, the children were previously healthy and are more than 1 year old. Respiratory symptoms were the leading cause of PICU admission, making respiratory support the principal therapy. Patients requiring mechanical ventilation showed deterioration on the first day of admission. These children seemed to require close monitoring, and multicenter studies are necessary.

Authors: Jung HK, Kim JY, Lee MS, Lee JY, Park JS, Hyun M, Kim HA, Kwon YS, Choi SW, Moon SM, Suh YJ Abstract OBJECTIVE: We investigated the prevalence of pneumonia in novel coronavirus disease 2019 (COVID-19) patients using chest radiographs to identify the characteristics of those with initially negative chest radiographs, who were positive for pneumonia on follow-up. MATERIALS AND METHODS: Retrospective cohort data of 236 COVID-19 patients were reviewed. Chest radiography was performed on admission, with serial radiographs obtained until discharge. The 'positive conversion group' was defined as patients whos...

Authors: Hwang EJ, Kim H, Yoon SH, Goo JM, Park CM Abstract OBJECTIVE: To describe the experience of implementing a deep learning-based computer-aided detection (CAD) system for the interpretation of chest X-ray radiographs (CXR) of suspected coronavirus disease (COVID-19) patients and investigate the diagnostic performance of CXR interpretation with CAD assistance. MATERIALS AND METHODS: In this single-center retrospective study, initial CXR of patients with suspected or confirmed COVID-19 were investigated. A commercialized deep learning-based CAD system that can identify various abnormalities on CXR was impl...
