Dermatology-Related Emergency Department Visits in Tertiary Care Center in Riyadh, Saudi Arabia: A Descriptive Study.

: Dermatological complaints are commonly seen in the emergency department (ED) setting and may be attributed to infectious, inflammatory, allergic, hypersensitivity, or traumatic processes, yet few studies have been carried out in Saudi Arabia addressing this topic. This study, therefore, aimed to explore this issue by investigating the most common dermatology-related ED encounters in a large tertiary care center in Riyadh, Saudi Arabia, and estimating the incidence of these encounters. : This was a retrospective cohort study conducted in the ED of King Abdulaziz Medical City, a tertiary care center in Riyadh, Saudi Arabia.

Recent advances of piezo-catalysis and photocatalysis for efficient environmental remediation.

The efficient degradation of organic pollutants in diverse environmental matrices can be achieved through the synergistic application of piezo-catalysis and photocatalysis. The focus of this study is on understanding the fundamental principles and mechanisms that govern the collaborative action of piezoelectric and photocatalytic materials. Piezoelectric nanomaterials, under mechanical stress, generate piezo-potential, which, when coupled with photocatalysts, enhances the generation and separation of charge carriers.

Efficient Adsorption and Removal of the Herbicide 2,4-Dichlorophenylacetic Acid from Aqueous Solutions Using MIL-88(Fe)-NH.

Metal-organic frameworks (MOFs), a material known for its multifunctionality, chemical stability, and high surface area, are now commonly utilized as an adsorbent for water treatment. The MOF (MIL-88(Fe)-NH) was synthesized and used to remove the commonly used toxic herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) from water. The MIL-88(Fe)-NH MOF was fully characterized using multiple techniques.

Sunlight-Driven Photocatalytic Active Fabrics through Immobilization of Functionalized Doped Titania Nanoparticles.

Frequent washing of textiles poses a serious hazard to the ecosystem, owing to the discharge of harmful effluents and the release of microfibers. On one side, the harmful effluents from detergents are endangering marine biota, while on the other end, microplastics are observed even in breastfeeding milk. This work proposes the development of sunlight-driven cleaning and antibacterial comfort fabrics by immobilizing functionalized Zn-doped TiO nanoparticles.

Different Dimensionalities, Morphological Advancements and Engineering of g-C N -Based Nanomaterials for Energy Conversion and Storage.

Graphitic carbon nitride (g-C N ) has gained tremendous interest in the sector of power transformation and retention, because of its distinctive stacked composition, adjustable electronic structure, metal-free feature, superior thermodynamic durability, and simple availability. Furthermore, the restricted illumination and extensive recombination of photoexcitation electrons have inhibited the photocatalytic performance of pure g-C N . The dimensions of g-C N may impact the field of electronics confinement; as a consequence, g-C N with varying dimensions shows unique features, making it appropriate for a number of fascinating uses.

Cholecysto-hepatic fistula in type III gallbladder perforation: A rare etiology of liver abscess; case report.

Introduction And Importance: Gallbladder perforation (GBP) with cholecystohepatic fistula is an extremely rare complication of acute and/or chronic gallbladder diseases. Niemeier classified GBP into three types each characterized by specific signs and symptoms. Radiological investigations such as abdominal ultrasonography (USG) and computed tomography (CT) are crucial to evaluate and diagnosing GBP, while fistulae are usually identified intraoperatively.

Development of Thermochromic Ink Using the Anthocyanidin-Based Red-Cabbage Extract for Anticounterfeiting Applications.

Temperature-driven colorful switching inks have been an interesting security encoding method to improve the anticounterfeiting properties of commercially available merchandise. Recently, thermochromic inks have faced many disadvantages, such as low efficiency, high cost, and low durability. In the current study, we developed self-healable ink from poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPSA) integrated with the anthocyanidin(ACY)-based red-cabbage extract in the presence of ferrous sulfate for authentication purposes.

National research guideline for prehospital emergency medical care: A prospective Delphi-study.

Objectives: To identify the most important research topics to establish a national research agenda and protocol for prehospital research in Saudi Arabia (KSA).

Methods: A 3-round modified Delphi consensus methods were used to determine high-priority research topics. Round I included an open-ended question to list all high-priority research topics in a prehospital setting in Riyadh, KSA.

Nurses experience of caring for patients with COVID-19: A phenomenological study.

Introduction: COVID-19 has impacted all dimensions of life and imposed serious threat on humankind.

Background: In Jordan, understanding how nurses experienced providing care for patients with COVID-19 offers a framework of knowledge about similar situations within the context of Arabic culture.

Aim: To explore nurses' experience with providing hands-on care to patients with active COVID-19 infection in an Arabic society.

Giant omental lipoma, a rare etiology of right-iliac fossa pain in adult: A surgical case report.

Background: Omental lipoma is an uncommon abdominal tumor of mature fat cells. Those benign tumors are usually asymptomatic but occasionally can cause signs and symptoms based on their location, size, and presence of complications. Radiological investigations such as Abdominal ultrasonography (USG) and computed tomography (CT) are crucial to evaluate and diagnose intra-abdominal tumors, especially omental lipomas.

Awareness about the relation of noise induced hearing loss and use of headphones at Hail region.

Background: Noise induced hearing loss is the one of the most preventable causes of hearing loss in all age groups. Occupational, environmental, infectious and genetic factors all play a role in determining the level of hearing loss. However, the use of headphones and personal listening devices is now very common, especially in younger generations.
