Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-1), notoriously known as COVID-19, emerged in 2019 and was responsible for causing acute respiratory collapse. Moreover, in September 2020, new variant cases of severe acute respiratory syndrome coronavirus 2 were reported in the United Kingdom, with many patients and deaths. This study aimed to see knowledge, perception, and fear among the global population towards a new variant of severe acute respiratory syndrome coronavirus 2, known as Omicron (B.1.1.529). This online cross-sectional global study was conducted during the emergence of the B.1.1.529 variant, also known as the Omicron variant. The survey was carried out from 2nd December 2021 to 3rd January 2022. The descriptive analysis was presented as frequencies (N), percentages (%), and mean ± standard deviation (m ± SD). The association between dependent and categorical independent variables was determined using the Chi-square test (x2). Statistical analysis was performed by using SPSS version 23. Of 353 respondents, approximately 61% were females. One hundred fifty-four respondents were in the age group of 18–27 years. The average age was 31.53±10.3 (mean± SD). The majority of respondents (43.9%) were from Indonesia. The mean knowledge score about the Omicron variant was 3.18±1.14. Our study suggests that people have some knowledge about the new variant, Omicron (B.1.1.529). Besides, there was a significant association (p = 0.05) for the perception of the fatality rate of Omicron among the respondents from different countries. However, there is still an ample research gap in enlightening people about this infection (B.1.1.529).
Acute calcific tendinitis of the longus colli muscle (LCM) also called acute calcific prevertebral tendinitis or retropharyngeal tendinitis is an inflammatory process of the LCM that results in acute and debilitating symptoms. Although the imaging appearances of this uncommon condition are specific, due to the rarity of this entity and lack of familiarity, it can be sometimes misdiagnosed as a retropharyngeal abscess. This case report presents characteristic radiological features of the acute calcific tendinitis of the LCM, which may be helpful for the emergency radiologist to accurately diagnose this condition to avoid unnecessary surgical interventions.
Paraneoplastic neurological syndrome (PNS) associated with anti-CV2/CRMP5 antibodies is a rare entity that can present in various clinical manifestations, from encephalitis to chorea, depending on the brain region involved. We report a case of an elderly person with small cell lung cancer who presented with PNS encephalitis associated with anti-CV2/CRMP5 antibodies which were confirmed on immunological analysis.
Aim: To assess the efficacy of the greyscale and Doppler ultrasound in the diagnosis of hepatoma in chronic liver disease patients. Study Design: Prospective study. Place and duration of study: Department of Radiology, Jinnah Postgraduate Medical Centre Karachi from 1st October 2021 to 30th June 2022. Methodology: One hundred and twenty patients who were diagnosed with chronic liver diseases and were suspected of hepatocellular carcinoma were included in this study. Ultrasonography was conducted under grey scale Doppler scanning in each patient after 6 hours of fasting at 3-6 megahertz with a curvilinear probe in supine as well as oblique position. Sensitivity, specificity as well as the predictive value of the image formed through the ultrasonography machine was assessed. Results: The age of the patients was 46.5±6.5 years and there were 78 (65%) males whereas 42 (35%) were females. On the grey scale Doppler scan, there was 53% of cases seen confirmed for the presence of hepatoma. The sensitivity and specificity were observed in 65% and 85% of the grey scale Doppler ultrasonography while the positive predictive value was 92% respectively. Conclusion: Greyscale Doppler scan is an efficient and reliable method for the detection of hepatoma and can be used in clinically confirmed cases of chronic liver disease as a screening tool. Keywords: Hepatoma, Greyscale, Doppler ultrasound, Chronic liver disease
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
