Introduction And Importance: Stricture formation is a well-known Crohn's disease consequence that usually results from recurrent cycles of inflammation and healing and primarily affects the small intestine.

Case Presentation: In this report, we describe the case of a 35-year-old male with an 18-year history of Crohn's disease complicated by long-kinked ileal stricture who presented with a 3-month history of subacute small intestinal obstruction diagnosed with MR enterography and underwent failed medical treatment.

Clinical Discussion: The patient, a male showing signs of wasting due to a prolonged subacute small intestinal obstruction, underwent an MR enterography which revealed a 6-cm kinked ileal stricture.

Assessment of the quality of orthodontic care in a UAE-based orthodontic postgraduate training institution was conducted using multiple indices, including the Peer Assessment Rating (PAR), American Board of Orthodontics Objective Grading System (ABO-OGS), and Index of Complexity Outcome and Need (ICON). Retrospective evaluation of pre- and post-treatment records of patients (n = 201) treated with fixed orthodontic appliances was performed by two examiners Statistical analysis assessed the influence of gender, type of malocclusion, need for extraction, missed appointments and number of treating residents on treatment duration. The average numerical reduction of the PAR and ICON scores at the start and end of the treatment were 17.

This study aimed to evaluate the potential of phytochemicals from two native UAE plant species, Arthrocnemum macrostachyum and Tamarix nilotica, as anti-cancer agents. The plant extracts were obtained using two methods, maceration, and microwave-assisted extraction (MAE), and were subsequently evaluated for their in vitro cytotoxicity against three cancer cell lines: breast (MDA-MB-231), colon (HCT-116), and lung (A-549). Results suggest that: 1) MAE is more efficient than maceration in recovering metabolites from plant biomass based on measurements of total phenolic content, radical scavenging activity, and bioactivity of extracts based on in vitro cytotoxicity.

Objective: Recently, angiotensin-converting enzyme 2 (ACE2) gene has emerged as a potential candidate gene for susceptibility to SARS-CoV-2 infection. We investigated whether ACE2 G8790A (rs2285666) polymorphism could be a genetic marker for susceptibility to COVID-19 and disease severity in Egyptian children and adolescents.

Methods: This was a prospective case-control study included 580 cases diagnosed with COVID-19, and 580 matched control children and adolescents.
