Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has spread worldwide causing a global pandemic. In this context, lung ultrasound (LUS) has played an important role due to its high diagnostic sensitivity, low costs, simplicity of execution and radiation safeness. Despite computed tomography (CT) being the imaging gold standard, lung ultrasound point of care exam is essential in every situation where CT is not readily available nor applicable. The aim of our review is to highlight the considerable versatility of LUS in diagnosis, framing the therapeutic route and follow-up for SARS-CoV-2 interstitial syndrome.

Impact On Treatment

SummaryHundreds of millions got infected, and millions have died worldwide and still the number of cases is rising.Chest radiographs and computed tomography (CT) are useful for imaging the lung but their use in infectious diseases is limited due to hygiene and availability.Lung ultrasound has been shown to be useful in the context of the pandemic, providing clinicians with valuable insights and helping identify complications such as pleural effusion in heart failure or bacterial superinfections. Moreover, lung ultrasound is useful for identifying possible complications of procedures, in particular, pneumothorax.Associations between coronavirus disease 2019 (COVID-19) and cardiac complications, such as acute myocardial infarction and myocarditis, have been reported. As such, point of care echocardiography as well as a comprehensive approach in later stages of the disease provide important information for optimally diagnosing and treating complications of COVID-19.In our experience, lung ultrasound in combination with echocardiography, has a great impact on treatment decisions. In the acute state as well as in the follow-up setting after a severe or critical state of COVID-19, ultrasound can be of great impact to monitor the progression and regression of disease.

Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the digestive tract (1%). These tumors express the CD 117 in 95% of cases. The stomach is the preferential localization (70%). Diagnosis is difficult and sometimes late. Progress of imaging has greatly improved the management and the prognosis. Computed tomography (CT) is the gold standard for diagnosis, staging, and treatment follow-up. The increasing recognition of GIST’s histopathology and the prolonged survival revealed some suggestive imaging aspects. Key words: gastro-intestinal stromal tumors; computed tomography; diagnosis

Four patients presented to the Emergency Department with dyspnea and they underwent point-of-care ultrasound. Lung ultrasound showed a diffuse bilateral B-profile pattern-interstitial syndrome, they underwent contrast-enhanced computed tomography scan of thorax that showed multiple bilateral lung metastases. The detection, in a dyspneic patient, of a diffuse Bprofile pattern not attributable to traditional interstitial syndrome conditions (pulmonary fibrosis, acute respiratory distress syndrome, acute pulmonary edema, interstitial pneumonia) could be indicative of multiple pulmonary metastases.

Abstract Background To assess diagnostic performance of lung ultrasound (LUS) in identifying ARDS morphology (focal vs non-focal), compared with the gold standard computed tomography. Methods Mechanically ventilated ARDS patients undergoing lung computed tomography and ultrasound were enrolled. Twelve fields, were evaluated. LUS score was graded from 0 (normal) to 3 (consolidation) according to B-lines extent. Total and regional LUS score as the sum of the four ventral (LUSV), intermediate (LUSI) or dorsal (LUSD) fields, were calculated. Based on lung CT, ARDS morphology was defined as (1) focal (loss of aeration with lobar distribution); (2) non-focal (widespread loss of aeration or segmental loss of aeration distribution associated with uneven lung attenuation areas), and diagnostic accuracy of LUS in discriminating ARDS morphology was determined by AU-ROC in training and validation set of patients. Results Forty-seven patients with ARDS (25 training set and 22 validation set) were enrolled. LUSTOT, LUSV and LUSI but not LUSD score were significantly lower in focal than in non-focal ARDS morphologies (p < .01). The AU-ROC curve of LUSTOT, LUSV, LUSI and LUSD for identification of non-focal ARDS morphology were 0.890, 0.958, 0.884 and 0.421, respectively. LUSV value ≥ 3 had the best predictive value (sensitivity = 0.95, specificity = 1.00) in identifying non-focal ARDS morphology. In the validation set, an LUSV score ≥ 3 confirmed to be highly predictive of non-focal ARDS morphology, with a sensitivity and a specificity of 94% and 100%. Conclusions LUS had a valuable performance in distinguishing ARDS morphology.

Transthoracic Ultrasound

Background:Dermatomyositis is a multi organ autoimmune disease wich is commonly complicated with interstitial lung disease. Chest high-resolution computed tomography (HRCT) is still considered the diagnostic gold standard for interstitial lung disease and is quantification, however he increasing use of lung ultrasound may play an important role in the future.Objectives:The aim of our study was to determine the diagnostic value of lung ultrasound in the detection and progression of interstitial pulmonary disease in patients with dermatomyositis.Methods:Twenty two subjects with dermatomyositis diagnosed according to the American College of Rheumatology criteria were enrolled (6 males, 16 females; mean age: 15,8 ± 8.8 years; range: 6 to 29 years). All subjects underwent high resolution computed tomography followed by transthoracic ultrasound for comet tail sign detection and pleural irregularity in order to predict the degree of interstitial lung disease. The modified transthoracic ultrasound assessment was performed at 06 thoracic regions each side. The Warrick score was calculated according standard high-resolution chest computed tomography images that were evaluated independently from each other by two thoracics radiologists.Results:A significantly positive correlation between transthoracic ultrasound and the severity of pulmonary involvement, as seen by the number of B lines (Spearman ‘s correlation coefficient = 0.80, p < 0.001), and the number of positive areas (regions wih more than 3 B lines) (Spearman ‘s correlation coefficient = 0.75, p < 0.001) were found. When compared with high-resolution chest computed tomography as the gold standard method, the sensitivity, specificity, of transthoracic ultrasound was 96.4%, 83,3% respectively. Addicionally the number of B lines (sum of 35 or more B lines) and a number of B lines positive areas (7 or more regions with at least 3 B lines) cut of allowed to discriminate the inflamatory pattern (ground glass) to those with structural pattern (honeycomb and pulmonary cysts).Conclusion:Our study showed that transthoracic ultrasound comet tails scoring system could be useful in the assessment of the pulmonary involvement in patients with dermatomyositis, and should be considered as a primary screening exam to exclude lung involvement, rather than routine chest CT scans in assimptomatic patients.Disclosure of Interests:None declared

Lung ultrasoundClinical experience and scientific articles have shown that patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can be paucisymptomatic or asymptomatic at the time of diagnosis. In this paper, we will discuss two paucisymptomatic patients with blood tests suggestive for SARS-CoV-2 infection but with repeated negative nasopharyngeal swabs and without typical features of COVID-19 pneumonia on chest high-resolution computed tomography. In these cases, lung ultrasound helped to raise clinical suspicion of COVID-19 pneumonia and facilitate diagnosis.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused a global pandemic recently. The prevalence and persistence of antibodies following a peak SARS-CoV-2 infection provides insights into the potential for some level of population immunity. In June 2020, we succeeded in testing almost half of the population of an Austrian town with a higher incidence of COVID-19 infection. We performed a follow-up study to reassess the prevalence of SARS-CoV-2-specific IgA and IgG antibodies with 68 participants of the previous study. We found that the prevalence of IgG or IgA antibodies remained remarkably stable, with 84% of our cohort prevailing SARS-CoV-2-specific antibodies (only a slight decrease from 93% 4 months before). In most patients with confirmed COVID-19 seroconversion potentially provides immunity to reinfection. Our results suggest a stable antibody response observed for at least 6 months post-infection with implications for developing strategies for testing and protecting the population.
