Student academic performance in non-lecture physiology topics following the abrupt change from traditional on-site teaching to online teaching during COVID-19 pandemic.

Background: During the COVID-19 pandemic, pre-clerkship medical education, including all physiology classes, was obliged to change to online teaching due to limitations of on-site (face-to-face) classes. However, the effectiveness of online teaching in non-lecture physiology topics during the COVID-19 pandemic has not been thoroughly investigated.

Method: We conducted a prospective study to evaluate the students' academic achievement and opinions on online teaching during the COVID-19 academic year.

Sural-sparing pattern: A study against electrodiagnostic subtypes of Guillain-Barre syndrome.

Objective: To study sural-sparing pattern in GuillainBarre syndrome (GBS) and compare it among GBS's electrodiagnostic subtypes, classified by two recent criteria.

Methods: This study retrospectively reviewed clinical data and electrodiagnostic studies (EDXs) of 88 GBS patients diagnosed in a tertiary care hospital (2010-2019).

Results: Overall, 79/88 (89.
