Bilateral Corneal Endotheliitis Following Corneal Cross-linking with Riboflavin and Ultraviolet A.

This case report aims to document a case of bilateral endotheliitis occurring shortly after riboflavin-assisted cross-linking (CXL) in a young male patient with progressive keratoconus. The objective is to identify potential risk factors, treatment strategies, and outcomes while considering relevant literature on similar cases. A male in his late adolescence with bilateral progressive keratoconus underwent bilateral CXL using riboflavin and ultraviolet A light exposure.

Differentiation of acanthamoeba keratitis from other non-acanthamoeba keratitis: Risk factors and clinical features.

Introduction: Infectious Keratitis is one of the most common ocular emergencies seen by ophthalmologists. Our aim is to identify the risk factors and clinical features of Acanthamoeba Keratitis (AK).

Methods: This retrospective chart review study was conducted at King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia, and included all the microbial keratitis cases, male and female patients of all ages.

The Perception of Spectacles Use Among the General Population in Ha'il Region, Saudi Arabia: A Cross-Sectional Study.

Purpose: The study aims to assess the perception of optical spectacles use among the Ha'il region population in Saudi Arabia.

Patients And Methods: A cross-sectional survey was distributed via various social media applications to the residents of the Ha'il region. An online questionnaire was designed and included informed consent and questions assessing the participants' perceptions about wearing eyeglasses, contact lenses, and general eye health.

An Unusual Presentation of Hearing Impairment in an Adult with Pineal Region Germinoma: A Case Report.

Tumors of the pineal region typically present with symptoms and signs of mass effect and increased intracranial pressure. However, although rare and can be overlooked, hearing impairment is a potential clinical finding in these cases. The authors describe a 24-year-old male who presented to the emergency room complaining of bilateral hearing impairment.

The Use of Pain Severity and Its Impact as a Predictor for MRI Findings: A Cross-Sectional Study in Ta'if, Saudi Arabia.

Background Low back pain (LBP) is common and considerably impacts daily lives across all age groups. MRI is not frequently used as a first-line investigation for patients presenting with LBP, except in the presence of red-flag symptoms. This study aimed to use pain severity and its impact as a predictor for MRI findings to help physicians decide whether a patient needs an MRI.

Photoelectrocatalytic treatment of municipal wastewater with emerging concern pollutants using modified multi-layer catalytic anode.

Municipal wastewater contains emergent chemical and biological pollutants that are resistant to conventional wastewater treatments. Therefore, the focus of the current study was to address the challenge of removing emergent chemical and biological pollutants present in municipal wastewater. To achieve this, a photo electro-catalytic (PEC) treatment approach was employed, focusing on the removal of both micro and biological pollutants that are of emergent concern, as well as the reduction of Chemical Oxidation Demand (COD) and Total Organic Carbon (TOC).

Modified bio-electrocoagulation system to treat the municipal wastewater for irrigation purposes.

A modified biological-integrated electrocoagulation method was explored to treat municipal wastewater (MWW) for irrigation purposes. To use treated wastewater for irrigation purposes a wide range of contaminants removal was focused on in this study (turbidity, hardness, conductivity, TDS, TSS, chloride, Ammonia nitrogen, BOD, COD, and total coliform). Raw municipal wastewater (RMWW) was treated in a modified Bio-Electrocoagulation (BEC) cell.

Variability of ophthalmology residents' perception toward different major training programs in Saudi Arabia.

Purpose: The constant demand for ophthalmologists has nationally resulted in creating more programs in different regions of the kingdom. We have previously reported the overall residents' satisfaction with the current local ophthalmology curriculum and the competency of the ophthalmic training (clinical and surgical) in our local programs in Saudi Arabia compared to international standards. In this study, we aim at comparing the major local training programs and analyze the differences among them aiming at improving our training.

Assessment of Cortical Plasticity in Schizophrenia by Transcranial Magnetic Stimulation.

Neural plasticity refers to the capability of the brain to modify its structure and/or function and organization in response to a changing environment. Evidence shows that disruption of and altered functional connectivity between distinct brain networks contribute significantly to the pathophysiological mechanisms of schizophrenia. Transcranial magnetic stimulation has emerged as a noninvasive brain stimulation tool that can be utilized to investigate cortical excitability with the aim of probing neural plasticity mechanisms.

Comparison of the characteristics and outcomes of traumatic wound dehiscence after penetrating or Lamellar Keratoplasty for Keratoconus.

Purpose: To examine the incidence, causes, characteristics, and the visual outcome of traumatic wound dehiscence (TWD) after penetrating keratoplasty (PK) compared to lamellar keratoplasty (LKP) for keratoconus.

Methods: The medical records of all keratoconus patients undergoing TWD repair after PK or LKP over a 7-year period at the King Khaled Eye Specialist Hospital (KKESH), Riyadh were reviewed. Data were collected on patient demographics, interval between keratoplasty and trauma, and characteristics and visual outcomes of TWD.

Phosphonium-based Ionic Liquid Modified Activated Carbon from Mixed Recyclable Waste for Mercury(II) Uptake.

The contamination of water surfaces by mercury is a dangerous environmental problem due to its toxicity, which leads kidney damage. Activated carbon from mixed recyclable waste modified by phosphonium-based ionic liquid (IL-ACMRW) was therefore prepared and evaluated for Hg(II) remediation. The activated carbon used in this study was prepared from mixed waste, including cardboard, papers and palm wastes as cheap raw materials.

Morbidity and mortality after fragility hip fracture in a Saudi Arabian population: Report from a single center.

Objective To determine the functional morbidity and mortality after fragility hip fracture and compare the mortality with three other common diseases. Methods Data were collected from patients admitted to King Fahd Hospital of the University, AlKhobar from January 2010 to December 2014. Demographic data included the preoperative American Society of Anesthesiologists (ASA) score as assessed by the anesthetist and the type of surgery.
