Abstract
Background: The advent of Severe Acute Respiratory Syndrome Coronavirus 2 (so-called SARS-CoV-2) causing Coronavirus Disease 2019 (so-called COVID-19) occurred in Dec. 2019 in Wuhan, China. Having an inconceivable worldwide contagion, the outbreak was labeled a pandemic by the WHO. Dental services and related professions (including dentists, dental assistants, dental hygienists and the personnel of cleansing, remedial, triage, dental laboratories, radiographic laboratories and other related paraclinicals), facing galore aerosol and droplets, are in the topmost risk groups exposed to the queer virus. This study was fulfilled to round up evidence-based data to break a link at any part of the virus transmission chain in dental services and related professions.
Methods: Relevant online databases, as PubMed, MEDLINE, Embase, Scopus, Google Scholar and TripDatabase were searched meticulously and evaluated for relevant published original research papers. Subsequently, to fulfill the investigation, ADA, CDC and WHO websites were reviewed to gain relevant guidelines and protocols. Consequently, 476 resources were included considering the canonical inclusion criteria. For the sake of quality assessment of the resources, an authentic checklist was exploited to score the resources from 1 to 15, wherein the admissible score was 10. After deliberation of resources, 366 of them were excluded and finally, 110 resources were selected and overhauled to attain a comprehensive perception on the subject of the investigation.
Results: Transmission of SARS-CoV-2 includes direct transmission (via droplet and aerosol inhalation) and indirect transmission (via surface and instrument contamination), which can amply occur in dental services and related professions. Therefore, an all-inclusive evidence-based miscellany was rallied on several exigent topics, containing genuine esteem in reputable scientific authorities, to present a consummate report for the dental clinicians and related practitioners, working in the course of the running pandemic.
Conclusion: Contemplating the ongoing crisis, undertaking a set of miscellany elected guidelines and protocols, is indispensable in this vital interval of history to bridle the current pandemic, which has been abridged via this systematic perusal. |

Abstract
Background: Trauma is one of the most common causes of death in all ages. Considering the prevalence of trauma in the general population, and its costs and complications, it is important to use aiding tools to accelerate the diagnosis in order to act in time. The aim of this study was to evaluate the efficacy of ultrasound in diagnosing nerve and tendon injuries in the upper extremities.
Methods: This study is a cross-sectional study, which was carried out at the emergency department of the Besat Hospital, Tehran from march 2018 to march 2019. The statistical population was all patients who had been referred with deep lacerations in upper extremities and had injuries in the superficial or deep compartments (nerves/ tendons). For all the patients who met the inclusion criteria, bedside sonography with 11 Mhz Linear probe was performed by the researcher and under the supervision of the radiologist. The results were compared with the results from local exploration of the wounds. Local exploration of the wounds was also done under the surgeon's supervision. After completing the sample size and data collection, SPSS software, version 22 (IBM SPSS, Armonk, NY, USA) was used for statistical analysis
|
Results: In this study, from 144 patients with penetrating trauma in the upper extremities, 56 patients were suspected with nerve injuries and 50 patients were suspected with tendon injuries. After evaluation with an ultrasound probe, 21 out of 23 cases suspected of nerve injuries were confirmed by local exploration. Local exploration confirmed that 27 out of 28 cases were suspected of tendon injuries. The accuracy of ultrasound in the assessment of nerve damage was estimated at 99.64% and in tendon damage at 92%, and the sensitivity of ultrasound in the diagnosis of nerve damage was 91.30% and in the diagnosis of tendon damage was 96.42%.
Conclusion: By the results of this research it can be concluded, that ultrasound leads to a faster diagnosis. It provides a wider field of view, can reduce possible secondary injuries and increases the accuracy of the diagnosis.
