Background: Gastroesophageal reflux disease (GERD) is a worldwide prevalent gastrointestinal disorder which has negative impacts on quality of life, health and economy. The aims of this study were to assess the prevalence of GERD among college students in southwestern Saudi Arabia and to evaluate its personal, academic and stress correlates Materials and Methods: Through a cross-sectional study design, a self-reported questionnaire was distributed between a representative sample of students in health and non-health care colleges in southwestern Saudi Arabia. The questionnaire included data for personal characteristics, academic study, and Arabic versions of GERD questionnaire (GerdQ) and Cohen's Perceived Stress Scale.

ABSTRACT PURPOSE: To evaluate a new technique of posterior capsulorhexis using air support to treat primary posterior capsular opacification (PCO) during cataract extraction surgery or to prevent post-operative PCO. SETTING: 1-Ophthalmology department, Faculty of medicine, Minia University, El-Minia, Egypt. 2- Security Forces Hospital, Ophthalmology Department, Riyadh, Kingdom of Saudi Arabia. DESIGN: Prospective, randomized case-control comparative study. Methods: 100 eyes of 100 patients with a mean age of 63.3 years with dens cataract. Fifty of them ( group 1) with primary PCO (discovered during the operations) and fifty (group 2) with clear posterior capsule. All cases undergone phacoemulsification, posterior capsulorhexis using the air to support the posterior capsule and separate it from the vitreous (the novel technique will be discussed later). Then IOL implantations wear done in the bag between the anterior and posterior capsular rim. Each patient was evaluated for the following:- visual acuity (UCVA and BCVA), intraocular pressure, intra ocular lens stability, visual axis opacification and posterior segment complications as retinal break, retinal detachment or cystoid macular oedema.
This clinical study investigates the sensation deficit in the lower lip and chin area after surgical correction of lower jaw deformity. The primary null hypothesis is: Lower jaw osteotomy cause no sensory deficit in the inferior alveolar nerve. The secondary null hypothesis is: Concurrent genioplasty with sagittal split does not increase the risk of sensory deficit in the inferior alveolar nerve.
This study aimed to develop a new approach for the treatment of fasting induced hypoglycemia during ramadan using mini-dose glucagon.
