<div>The ongoing pandemic of COVID-19 has shown</div><div>the limitations of our current medical institutions. There</div><div>is a need for research in the field of automated diagnosis</div><div>for speeding up the process while maintaining accuracy</div><div>and reducing computational requirements. In this work, an</div><div>automatic diagnosis of COVID-19 infection from CT scans</div><div>of the patients using Deep Learning technique is proposed.</div><div>The proposed model, ReCOV-101 uses full chest CT scans to</div><div>detect varying degrees of COVID-19 infection, and requires</div><div>less computational power. Moreover, in order to improve</div><div>the detection accuracy the CT-scans were preprocessed by</div><div>employing segmentation and interpolation. The proposed</div><div>scheme is based on the residual network, taking advantage</div><div>of skip connection, allowing the model to go deeper.</div><div>Moreover, the model was trained on a single enterpriselevel</div><div>GPU such that it can easily be provided on the edge of</div><div>the network, reducing communication with the cloud often</div><div>required for processing the data. The objective of this work</div><div>is to demonstrate a less hardware-intensive approach for COVID-19 detection with excellent performance that can</div><div>be combined with medical equipment and help ease the</div><div>examination procedure. Moreover, with the proposed model</div><div>an accuracy of 94.9% was achieved.</div>

Background: Many infants with congenital muscular torticollis (CMT) have deformational plagiocephaly (DP), and a small cohort also demonstrate mandibular asymmetry (MA). The aim of this retrospective study was to evaluate mandibular changes in these infants with previous computed tomography (CT) scans who underwent physical therapy (PT) to treat CMT. Methods: A retrospective study included patients presenting to a pediatric plastic surgery clinic from December 2010 to June 2012 with CMT, DP, and MA. A small subset of these patients initially received a 3D CT scan due to concern for craniosynostosis. An even smaller subset of these patients subsequently received a second 3D CT scan to evaluate for late-onset craniosynostosis. Patients were treated with PT for at least 4 months for CMT. Initial CT scans were retrospectively compared to subsequent CT scans to determine ramal height asymmetry changes. Clinical documentation was reviewed for evidence of MA changes, CMT improvement, and duration of PT. Results: Ten patients met inclusion criteria. Ramal height ratio (affected/unaffected) on initial CT was 0.87, which significantly improved on subsequent CT to 0.93 ( P < .05). None of the patients were diagnosed with craniosynostosis on initial CT. One patient was diagnosed with late-onset coronal craniosynostosis on subsequent CT. Conclusions: We identified a small cohort of infants with MA, CMT, and DP. These patients uniformly demonstrated decreased ramal height ipsilateral to the affected sternocleidomastoid muscle. Ramal asymmetry measured by ramal height ratios improved in all infants undergoing PT.
