The rising demand of chest imaging during the COVID-19 pandemic has necessitated adaptations to be made to the workflow in radiology departments, particularly in regard to personal protective equipment (PPE) guidelines and operations protocol. The guidelines were implemented to reduce the risk of disease transmission to frontline radiology personnel. With the rising number of COVID cases in the community, suspected COVID patients may present to our hospital’s Emergency Department (ED) even though it is not a COVID-designated hospital. Patients who present to ED are stratified as Severe Acute Respiratory Infection (SARI) cases if they exhibit respiratory symptoms, and non-SARI for those without respiratory symptoms. Imaging examinations performed for SARI patients must adhere to the new workflow. Radiographers and doctors performing Computed Tomography (CT), ultrasound and mobile radiography who come in contact with SARI patients must don full PPE. Prior to mobilization of patients, the routes must be cleared, and the cleaning team will standby for terminal cleaning. For portable examinations, donning and doffing of PPE is done in the department. All appliances must be covered prior to examination and sanitized after. Guidelines for usage of common areas such as pantry and prayer room are also employed to avoid crowding and to maintain adequate physical distancing. Adherence to the new workflow and guidelines is imperative to prevent workplace transmission from patients or other healthcare workers.
INTRODUCTION: Breast density is associated with an increased risk of developing breast cancer. The present study aims to determine the distribution and interobserver variability of mammographic breast density in patients with invasive breast carcinoma, using the fifth edition of BI-RADS guidelines. It is part of a larger study to ascertain the association between mammographic breast density and breast cancer characteristics. MATERIALS AND METHODS: Two radiologists independently assessed 122 mammograms of patients with histologically confirmed invasive breast carcinoma and assigned the breast density to categories A-D based on the fifth edition of BI-RADS guidelines. The interobserver variability was calculated using the weighted kappa coefficient and the level of agreement was determined using the Landis and Koch guidelines. RESULTS: In this study, 55.7% of patients with invasive breast carcinoma were assigned to category B, followed by category C with 36.1%. Only 4.1% of patients were assigned to categories A and D respectively. There was substantial agreement between the two readers’ judgement, k=0.610 (95% CI, 0.523-0.697), p < 0.001 for specific BI-RADS categories. CONCLUSION: Among patients with invasive breast carcinoma, there were more patients with non-dense breasts than dense breasts. Overall, there is a substantial interobserver agreement when radiologists used the fifth edition of the BI-RADS guideline, which is in line with results found in the literature. This suggests that the BI-RADS density classification is an acceptable method and can be reliably used in clinical practice.
Concha bullosa (CB) is a pneumatised middle turbinate. Although CB is the most common variant of the middle turbinate, the formation of mucocele or mucopyocele of CB has been rarely reported. The inflamed mucosal lining of the concha bullosa may lead to mucocele formation. Infection of the retained secretion will later on lead to mucopyocele. We report a 12-year-old girl presented with right unilateral nasal blockage associated with rhinitis symptoms. She was initially diagnosed as nasal polyp which later on turned out to be a mucocele histpathologically.Bangladesh Journal of Medical Science Vol.17(4) 2018 p.691-693
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.
