Prevalence of The Arterial Hand Dominance Using the Modified Allen Test and Pulse Oximetry among Plastic Surgery Patients.

Background: The ulnar and radial arteries are the major source of blood supply in the hand, as they form the superficial and deep palmar arches. Arterial hand circulation is one of the most complicated arterial trees and connections in the body, with tremendous variations in its structure. This study aimed to evaluate whether the ulnar artery or radial artery is the dominant artery in hand circulation among plastic surgery patients at King Khalid University Hospital and to correlate the arterial hand dominance with handedness and gender.

Orbital Intradiploic Epidermoid Cyst: A Case Report of a Rare Entity.

Cranial epidermoid cysts are relatively rare. More frequently reported in middle-aged men with a wide variety of signs and symptoms such as headache, seizures, cerebellar and cranial nerve deficits/visual disturbance. The approach for surgical removal of the cyst depends on its size and location.

Analysis of Gremlin 1 Levels Following Sleeve Gastrectomy.

Background: In the current study, we aimed to assess the levels of Gremlin 1, an adipokine with a rich repertoire of metabolic effects, in association with the glycemic and lipid parameters after sleeve gastrectomy.

Material And Methods: This study was conducted on 31 males with obesity aged 25 to 50 years who underwent sleeve gastrectomy. Plasma Gremlin 1 levels were evaluated using enzyme-linked immunosorbent assay (ELISA) at baseline and 6-12 months after the operation, along with body mass index, insulin, glucose, and lipid profile.
