Multichannel intraesophageal impedance with pH metry in Saudi children.

Background: Multichannel Intraesophageal Impedance with pH (MII-pH) provides complete characterization of gastroesophageal reflux (GER). The aim of this study was to report our experience in this relatively new technique, emphasizing the challenges in the performance and interpretation of the results.

Methods: The study was conducted at King Khalid University Hospital at King Saud University in Riyadh.

Frequency and predictive factors for spontaneous normalization of anti-tissue transglutaminase-IgA serology among Saudi children with type 1 diabetes mellitus: A cohort study.

Background: Celiac serology can be transiently elevated in patients with type 1 diabetes mellitus (T1DM) and normalized despite gluten consumption. This study aimed to identify the frequency and predictive factors of spontaneous normalization of anti-tissue transglutaminase (anti-TTG-IgA) antibodies in these patients.

Methods: The charts of all patients (≤18 years) with T1DM were retrospectively reviewed from 2012 to 2021 at a tertiary care center in Riyadh, Saudi Arabia.

Cost effectiveness of rivaroxaban versus warfarin among nonvalvular atrial fibrillation patients in Saudi Arabia: A Single-Center retrospective cohort study.

Background: Rivaroxaban is a novel oral anticoagulant (NOAC) that is commonly used for stroke prevention among patients with atrial fibrillation (AF). However, its cost effectiveness in reducing the risk of hospitalization and mortality in comparison to warfarin among nonvalvular AF patients in Saudi Arabia is largely unknown.

Methods: This was a single-center retrospective chart review of adult patients (≥18 years) with nonvalvular AF who were treated with warfarin or rivaroxaban for at least 12 months.
