Diagnostic accuracy of clinical signs and symptoms of COVID-19: A systematic review and meta-analysis to investigate the different estimates in a different stage of the pandemic outbreak.

Background: The coronavirus (COVID-19) pandemic caused enormous adverse socioeconomic impacts worldwide. Evidence suggests that the diagnostic accuracy of clinical features of COVID-19 may vary among different populations.

Methods: We conducted a systematic review and meta-analysis of studies from PubMed, Embase, Cochrane Library, Google Scholar, and the WHO Global Health Library for studies evaluating the accuracy of clinical features to predict and prognosticate COVID-19.

Efficacy of Spirulina 500 mg vs Triamcinolone Acetonide 0.1% for the Treatment of Oral Lichen Planus: A Randomized Clinical Trial.

Aim: The present study aimed at evaluating the efficacy of spirulina 500 mg in reducing the burning sensation and lesion size in oral lichen planus (OLP).

Dermatoglyphic Analysis in Parents with Cleft Children: A Comparative Study.

Background And Objective: There were studies in the literature which showed the altered dermatoglyphics in the cleft children. But it would be beneficial if probable expression can be proved in prior generations, so that genetic counseling and other preventive measures can be undertaken. The aim of the study is to determine variations in dermatoglyphics of prior generations which would serve as bench markers to predict the occurrence of cleft in off springs.
