Perceptions of medical students at Najran University on the effectiveness of problem-based learning and team-based learning.

Background: Team-based learning (TBL) and problem-based learning (PBL) are two effective educational approaches used in medical education for increasing knowledge acquisition, learning motivation, and collaborative and communication skills among students. Few studies have been conducted in Saudi Arabia to evaluate medical students' perceptions of these approaches.

Endoscopic Optic Nerve Decompression for Optic Neuropathy in Sinonasal Fibro-Osseous Tumors.

Background: Sinonasal fibro-osseous tumors involving the skull base sometimes result in the encasement of the optic canal and can cause the compressive optic neuropathy. This study aimed to elucidate the optimal timing of endoscopic optic nerve decompression (OND) in cases with optic neuropathy caused by fibro-osseous tumors.

Methods: Medical records were reviewed retrospectively from July 2008 through November 2016.
