Acute chest syndrome in pediatric sickle cell disease: A 19-year tertiary center experience.

Introduction: The most common cause of death among sickle cell disease (SCD) patients is acute chest syndrome (ACS). Since SCD is a common condition in the Eastern province of the Kingdom of Saudi Arabia (KSA), we aimed to provide a detailed description of the clinical characteristics and ACS management.

Methods: We retrospectively studied pediatric (<14 years) patients with SCD diagnosis who were admitted with ACS or developed ACS after admission from January 2002 to December 2020.

Predictors of Recurrent Acute Chest Syndrome in Pediatric Sickle Cell Disease: A Retrospective Case-Control Study.

Acute chest syndrome (ACS) is a common cause of death in sickle cell disease (SCD) patients. Multiple studies investigated the risk factors of developing ACS; however, predictors of recurrent ACS episodes have not been thoroughly investigated. We aim to examine the clinical and laboratory predictors of recurrent ACS in pediatric patients with SCD.

Adenomyoepithelioma of the Breast: A Report of 3 Cases.

BACKGROUND Breast adenomyoepithelioma is a rare benign breast tumor characterized by a biphasic proliferation of epithelial and myoepithelial cells with variable clinical and diagnostic features. Establishing the diagnosis, determining optimal therapy, and predicting outcome are problematic because of the rarity of this entity. There have been only 2 large series of adenomyoepitheliomas of the breast, reported by Tavassoli and Rosen, which included 27 and 18 patients, respectively.

Giant Esophageal Leiomyoma: Diagnostic and Therapeutic Challenges.

BACKGROUND Leiomyoma is a rare, benign, esophageal tumor that does not often measure >10 cm. Here, we report a case of giant esophageal leiomyoma in a 24-year-old man. CASE REPORT A 24-year-old man who smoked and had primary hypertension and glucose-6-phosphate dehydrogenase deficiency presented with a history of shortness of breath and productive cough with yellowish sputum, a long history of dysphagia to solid food, and a weight loss of 7 kg over 2 months.

High-Flow Nasal Cannula Treatment in Patients with COVID-19 Acute Hypoxemic Respiratory Failure: A Prospective Cohort Study.

Background: Early use of high-flow nasal cannula (HFNC) decreases the need for endotracheal intubation (EI) in different respiratory failure causes. While HFNC is used in coronavirus disease 2019 (COVID-19)-related acute hypoxemic respiratory failure (AHRF) under weak recommendations, its efficacy remains to be investigated.

Objectives: The primary objective was to examine HFNC efficacy in preventing EI among COVID-19 patients with AHRF.
