There is a scarcity of data on lung ultrasound (LUS) in SARS-CoV-2 pneumonia. As with many other pulmonary conditions, ultrasound may be a better diagnostic tool than routine chest radiography. In an era where computed tomography scanning is deferred because of the potential for cross-contamination, we evaluated the ability of LUS to detect a pattern of lung injury in SARS-CoV-2 pneumonia. A limited anterolateral LUS was performed to limit time spent in isolation rooms by ultrasound operators. We chose to use a hand-held ultrasound device due to portability and superior confidence in infection control. Both linear and phased array probes were used to obtain images of the pleura and lung. Of 69 patients who had lung ultrasound images saved and were included in the analysis, 36 were positive for SARS-CoV-2. Multifocal confluent B-lines, pleural irregularities, and the absence of moderate or large pleural effusions were the predominant pattern observed in most (86%) of SARS-CoV-2–positive patients. We evaluated the accuracy of the above criteria (LUS-CoV) and report a high sensitivity (91%) and specificity (86%) for SARS-CoV-2 pneumonia. In conclusion, a characteristic sonographic pattern of multifocal confluent B-lines with irregular pleural markings was seen on LUS in patients with SARS-CoV-2 pneumonia.

Background:The outbreak of Corona Virus Disease 2019 and the given nature of the virus how easily it may spread from one individual to other and through common dental procedures via aerosols, has resulted in shutting down of approximately 198,000 active dentists and dental specialists in USA. Materials and Method:One thousand dental students of BDS first year to final year were enrolled in the study. The questionnaire consisting of COVID 19 related questions was distributed to the students and all of subjects replied back. Questionnaire included ten questions in order to collect information about the various aspects of COVID 19, Statistical Analysis: Statistical analysis of data was performed using Statistical Package for Social Sciences (SPSS Inc. Chicago, IL, version 16.0). Results and Observations:Out of 1000, 450 were males and 550 students were females. All the participants have heard about the pandemic. Ninety six percent had knowledge about the etiology of the disease, 74 % were familiar that it spreads by aerosols. It was found out that majority of the participants (86%) had knowledge of importance of social distancing in preventing the spread of the disease. 47% participants reported that COVID 19 is common in children as compared to old age. Conclusion:The results of the study reported that dental students had knowledge about various aspects of COVID-19. Because of the limited sample size and parameters of the present study, future studies with larger sample sizes are warranted. The attitude and practices of dental students should also be assessed in future studies.
