SARS-CoV-2 evolution has undergone several mutations since its initial emergence in late 2019. Successive mutations are a common characteristic of RNA viruses like coronavirus. The emergence of new variants is a result of mutations that differ in their characteristics such as their infectiousness and mortality. Several variants of concern have been identified since the start of the pandemic, including Alpha, Beta, Gamma, Delta, and Omicron. Each of these variants showed unique mutations that raised concerns about their transmission rate, disease severity, and vaccine efficacy. The omicron variant (XBB 1.6), also known as B.1.1.529, attracted significant attention due to its high number of mutations, particularly in the spike protein. These mutations have raised concerns about potential impacts on vaccine efficacy and their ability to evade immunity.

Background: Percutaneous coronary artery angiography (CAG) is commonly performed all over the world through the transfemoral approach (TFA) but now a days the transradial approach (TRA) for CAG is becoming popular in the world. And recently has gained acceptance among Bangladeshi interventional cardiologists. The aim of this study was to document novice single operator experience of the trans-radial approach to CAG and to examine the utility of dual hand circulation assessment prior to the TRA for assessing the procedural outcomes among the patients in a tertiary care hospital in Bangladesh.

Ranula is a pocket of mucus that forms under the tongue due to blockage of the salivary glands, usually causing swelling and discomfort. Treatment can range from conservative measures, such as hot compresses, to surgical interventions to drain or remove the affected gland. This article reports the case of a ranula in an 11-year-old patient, which was clinically diagnosed and confirmed after the marsupialization technique. The histopathological examination revealed typical characteristics, such as thin epithelial lining and the presence of mucin, proving the diagnostic hypothesis. The treatment was effective, contributing to the clinical and histopathological understanding of this condition. This case report contributes to the existing literature by providing clinical and histopathological insights that can guide healthcare professionals in effectively managing this condition
