Demographic and clinical profile of patients with chronic rhinosinusitis in Saudi Arabia.

Objectives: To determine the clinical features of patients with chronic rhinosinusitis at a tertiary hospital in Riyadh, Saudi Arabia.

Methods: A cross-sectional study was carried out at King Abdulaziz University Hospital, Riyadh, Saudi Arabia. We enrolled 660 male and female participants with medical records indicating a history of chronic rhinosinusitis between 2021 and 2022.

Utilization of telemedicine in rhinologic practice during COVID-19 pandemic.

Background: The only two preventive interventions available for COVID-19 have been social distancing and quarantine. These preventive measures challenge health care providers by causing cancelations of elective in-person outpatient clinic visits in many hospitals, particularly in otolaryngology clinics.

Objectives: To assess the applicability and feasibility of telemedicine in rhinology cases with a study of outcomes to guide rhinologists on indications of in-office visits.

Psychometric Arabic Sino-Nasal Outcome Test-22: validation and translation in chronic rhinosinusitis patients.

Background: The Sino-Nasal Outcome Test (SNOT)-22 has multiple items that reflect how nasal disease affects quality of life. Currently, no validated Arabic version of the SNOT-22 is available.

Objective: .

Prevalence and antimicrobial resistance pattern of multidrug-resistant enterococci isolated from clinical specimens.

Purpose: Vancomycin-resistant enterococci (VRE) pose an emerging problem in hospitals worldwide. The present study was undertaken to determine the occurrence, species prevalence, antibacterial resistance, and phenotypic and genetic characteristics of VRE isolated in Riyadh hospitals, KSA.

Materials And Methods: Two hundred and six isolates of enterococcal species were obtained from clinical samples.

The role of caspase activation and mitochondrial depolarisation in cultured human apoptotic eosinophils.

Caspases are key intracellular molecules in the control of apoptosis, but little is known concerning their relative contribution to the cascade of events leading to eosinophil apoptosis. We examined caspase-3, -8, and -9 activities in receptor ligation dependent apoptosis induction in the cultured eosinophils (CE). CE cultured alone for 48 hours exhibited constitutive apoptosis (12% ± 1.
