A New Proposed Combined CT and MRI Staging System for Covid-19-Associated Rhino-Orbito-Cerebral Fungal Infection: A Multi-center Study with Pathological Correlation.

Rationale And Objectives: To propose a combined computed tomography (CT) and magnetic resonance imaging (MRI) based classification system in the management of COVID-19-associated rhino-orbito-cerebral (C-ROC) fungal infection and to assess the reliability of such proposed staging system.

Materials And Methods: This was a multi-center prospective study conducted on 122 adults with previously confirmed COVID-19 infection. CT and contrast-enhanced MRI (CE-MRI) were performed for all patients.

Assessment of the ability of the radiological incudo-stapedial angle to predict the stapedotomy technique type: a prospective case-series study.

Purpose: This study aimed to propose a radiological classification of the incudo-stapedial angle by preoperative high-resolution computed tomography (HRCT) images and to highlight its importance for predicting the use of reversal-steps stapedotomy (RSS) rather than the traditional non-reversal technique.

Methods: We included 83 candidates for stapedotomy operation. Two physicians measured the radiological incudo-stapedial joint angle in the preoperative HRCT.

Ultrasound Elastography in the Diagnosis of Malignant Cervical Lymphadenopathy in Children: Can It Replace Surgical Biopsy?

Introduction:  We aimed to assess the accuracy of ultrasound elastography in detecting pediatric malignant cervical lymph nodes, and if this modality can obviate the need for surgical biopsies.

Material And Methods:  A prospective study from September 2017 to September 2020 included 64 children with persistent cervical lymphadenopathy. Patients were evaluated by meticulous history and physical assessment.

NFKB1 promoter -94 insertion/deletion ATTG polymorphism (rs28362491) is associated with severity and disease progression of rheumatoid arthritis through interleukin-6 levels modulation in Egyptian patients.

Objective: Rheumatoid arthritis (RA) is an inflammatory autoimmune disorder, which can cause progressive and functional disability. Previous data suggests that some inflammatory cytokines are dysregulated in patients with RA. Polymorphisms in the NFKB1 gene were studied in different populations with RA.
