Trichobezoar-induced gastric outlet obstruction in a 17-year-old girl: a case report.

Gastric outlet obstruction (GOO) is an uncommon, yet potentially severe, condition arising from multiple causes, including ingesting foreign bodies. The formation of plastic bezoars or trichobezoars due to swallowing indigestible materials remains a rare cause, especially among children exhibiting pica behavior (Vaughan The Rapunzel syndrome: an unusual complication of intestinal bezoar. 1968;:339-43).

A huge benign gastric schwannomas presented with upper and lower gastrointestinal bleeding: a case report and literature review.

Gastric schwannomas (GS) are rare mesenchymal tumors from Schwann cells in the gastrointestinal (GI) tract, representing 2-6% of such tumors. We report a 52-year-old woman who experienced abdominal pain, hematemesis, and melena, initially suspected of having a GI stromal tumor through ultrasound and computed tomography abdomen. Despite no active bleeding found during an upper endoscopy, she underwent a successful open subtotal gastrectomy, with histopathology confirming GS.

Neuroendocrine tumor of the appendix masquerading as acute appendicitis with a mucocele on CT scan: a rare finding.

Introduction: Neuroendocrine tumors (NETs) of the appendix are rare and are often discovered incidentally during surgery for acute appendicitis or other unrelated conditions (Modlin et al. in Gastroenterology 128:1717-1751, 2005, Alsaad et al. in Oncol Rep 16:1105-1109, 2006, Frilling et al.

An Extremely Rare and Aggressive Case of Undifferentiated Carcinoma With Osteoclast-Like Giant Cells of the Pancreas Presenting as a Paraneoplastic Syndrome: A Case Report and Literature Review.

Undifferentiated carcinoma with osteoclast-like giant cells (UC-OGC) is a rare tumor type of pancreatic cancer. Paraneoplastic syndromes, an idiopathic inflammatory myositis characterized by various skin manifestations (such as dermatomyositis (DM)), cannot be attributed to the primary tumor itself. Here, we report an unusual case of UC-OGC presenting as a paraneoplastic syndrome, the first reported from Saudi Arabia and the Arabian Gulf states.

Is Appendiceal Diverticulitis Mimicking Acute Appendicitis?

Appendicular diverticulitis (AD) is a rare entity characterized by the inflammation of the arising diverticulum of the appendix. It has been reported to carry a high risk of perioperative complications, such as bleeding and perforation. Furthermore, multiple articles have highlighted the importance of diagnosing AD early due to its strong association with malignancies.

A Rare Case and Presentation of Traumatic Penetrating Aortic Arch Injury: A Case Report and Literature Review.

A penetrating injury to the thoracic aorta is an extremely rare, life-threatening condition, with a high overall mortality rate. The incidence of a penetrating injury to the aortic arch is unknown because the majority of patients die before receiving adequate treatment due to excessive bleeding. Through a literature review, 23 cases of favorable outcomes were found.

Age estimation based on Willems method versus country specific model in Saudi Arabia children and adolescents.

Background: The aims of this study were to create a method for estimation of dental age in Saudi children and adolescents based on the Willems model developed using the Belgian Caucasian (BC) reference data and to compare the ability of the two models to predict age in Saudi children.

Methods: Development of the seven lower left permanent mandibular teeth was staged in 1146 panoramic radiographs from healthy Saudi children (605 male, 541 female) without missing permanent teeth and without all permanent teeth fully developed (except third molars). The data were used to validate the Willems BC model and to construct a Saudi Arabian-specific (Willems SA) model.

Influence of photodynamic therapy and different lasers Er,Cr:YSGG and Er,YAG on dentin conditioning bonded to conventional and bioactive cement.

Aim: The aim of the present study was to evaluate the bond integrity of bioactive cement (BA) in contrast to conventional cement Calibra (C) after dentin treated with different surface conditioners (PDT, EYL, ECL) MATERIALS AND METHODS: Sixty non-carious permanent mandibular molars were disinfected and embedded in acrylic resin till cement-o-enamel junction. For homogeneity the buccal surface were grounded and polished. Samples were categorized into three main groups based on conditioning technique.

The relationship between malocclusion and oral health-related quality of life among adolescents: a systematic literature review and meta-analysis.

Background: Malocclusion is a deviation from an anatomical norm that occurs in various populations. Evidence shows that it has physical and psychological implications as well as an influence on the patient's oral health-related quality of life (OHRQoL). Self-perception of oral health plays an important role in the understanding of malocclusion's influence on the quality of life.

Coronary artery rupture in blunt thoracic trauma: a case report and review of literature.

Background: Blunt thoracic trauma can rarely result in coronary artery injury. Blunt trauma can result in occlusion of any of the coronary arteries or can lead to its rupture and bleeding. Traumatic coronary artery occlusion can lead to myocardial infarction, while its rupture and bleeding can result in hemopericardium and cardiac tamponade, and can be rapidly fatal.

Working environment and specialty of choice chosen by the dental students at Prince Sattam Bin Abdulaziz University, Saudi Arabia: A cross-sectional study.

Objectives: This cross-sectional study was conducted to explore the specialty chosen by the dental students for postgraduate studies and the future aspirations of students in a Saudi Arabia dental college.

Materials And Methods: Of the total number of 120 questionnaires that were distributed, 107 subjects responded with selective responses and a response rate of 89%. A descriptive survey was conducted using one of the questionnaires among the students of dentistry at the dental college, Prince Sattam Bin Abdulaziz University, Al-Kharj among male students (men's college) for a period of 2 months.
