Effects of social networking services on academic performance and self-esteem: A cross-sectional study among medical students.

Background: Social networking services (SNS) are a subcategory of social media that provide a useful tool for an individual's practical life and social relations. Since the impact of SNS on students' lives is a relatively neglected topic, we aimed to investigate the effect of social media on academic performance and self-esteem.

Methods: A cross-sectional study was conducted with 373 medical students distributed across different academic years.

Tracheobronchial angles in children: Three-dimensional computed tomography-based measurements.

Background: Studies have shown significant variation in the tracheobronchial angles in pediatric-aged patients. The current study revisits tracheobronchial angle measurements in children using accurate computed tomography-based 3-dimensional images to add clarity to the understanding of tracheobronchial angles. The primary objective of the current study was to measure the right and left bronchial angle take off from the trachea using 3-dimensional computed tomography-based images of the air column in the tracheobronchial tree.

Development and validation of Arabic version of the Neuropathic Pain Questionnaire-Short Form.

Introduction: The Neuropathic Pain Questionnaire-Short Form (NPQ-SF) is the shortest diagnostic tool for the assessment of neuropathic pain, designed with the goal to differentiate between neuropathic and nonneuropathic pain. The aim of this study was to translate, culturally adapt, and validate the NPQ-SF questionnaire in Arabic.

Methods: A systematic translation process was used to translate the original English NPQ-SF into Arabic.

Upper airway in infants-a computed tomography-based analysis.

Background: Recent studies suggest that the pediatric airway is elliptical with the subglottis rather than the cricoid as the narrowest part contrary to the old belief of a funnel-shaped airway. The shape of the airway in neonates and infants has not been studied separately. This study seeks to define the shape of the upper airway in neonates and infants, and determine if there are differences in airway shape between infants and older children.
