A rare case of huge intracranial yolk sac tumor presenting as an orbital mass in an infant: case report and literature review.

Primary intracranial yolk sac tumor (YST) with orbital involvement is an exceedingly rare extragonadal germ cell tumor, with only a limited number of cases reported in the literature. Clinically, primary intracranial yolk sac tumor with orbital involvement may present with symptoms that mimic more common benign or malignant orbital disorders in children, potentially leading to diagnostic delays that can adversely impact survival. Diagnostic imaging modalities, including computed tomography (CT) and magnetic resonance imaging (MRI), are instrumental for assessing the tumor's size, precise localization, and extent.

Primary central nervous system lymphoma: A diagnostic challenge in a young immunocompetent patient with limited resources.

Primary central nervous system lymphoma is a rare form of central nervous system malignancy. It predominantly affects immunocompromised individuals and the elderly population. Diffuse large B-cell lymphoma is the most common type.

Association of vitamin intake with health-related quality of life in hemodialysis patients.

Background: It is still uncertain whether vitamin intake is associated with better quality of life in hemodialysis patients. This study aims to assess the association between the quantity of supplemented vitamins and health-related quality of life (HRQoL) in this population.

Materials And Methods: This cross-sectional study included all patients on chronic hemodialysis from three units.

Genomic characterization of SARS-CoV-2 in Egypt: insights into spike protein thermodynamic stability.

The overall pattern of the SARS-CoV-2 pandemic so far has been a series of waves; surges in new cases followed by declines. The appearance of novel mutations and variants underlie the rises in infections, making surveillance of SARS-CoV-2 mutations and prediction of variant evolution of utmost importance. In this study, we sequenced 320 SARS-CoV-2 viral genomes isolated from patients from the outpatient COVID-19 clinic in the Children's Cancer Hospital Egypt 57357 (CCHE 57357) and the Egypt Center for Research and Regenerative Medicine (ECRRM).
