Ketamine administration for acute painful sickle cell crisis: A randomized controlled trial.

Objective: The objective was to evaluate the efficacy and safety of single-dose ketamine infusion in adults with sickle cell disease (SCD) who presented with acute sickle vasoocclusive crisis (VOC).

Methods: This study was a parallel-group, prospective, randomized, double-blind, pragmatic trial. Participants were randomized to receive a single dose of either ketamine or morphine, infused over 30 min.

Atypical Presentation of Perforated Viscus as Biliary Colic.

Peptic ulcer is a defect in the mucosal layer of the stomach or duodenum that extends into the deeper layers of their walls. Patients with peptic ulcer disease (PUD) may be asymptomatic or have mild abdominal discomfort. It is one of the common etiologies of perforated viscus resulting in secondary peritonitis, a life-threatening condition that carries high risk for morbidity and mortality especially in those who present late to the hospital or due to unrecognized and misdiagnosed perforation.

Transperineal Ultrasound in the Diagnosis of Proctitis in the Emergency Department.

Background: Patients with anorectal complaints commonly present to the emergency department (ED). In patients with prior history of pelvic radiation and those with risk factors for sexually transmitted infections, proctitis is frequently on the differential diagnosis. Computed tomography (CT) scans are frequently done in patients with atypical presentations and those with broader differential diagnoses.

Nitrous oxide inhalant abuse and massive pulmonary embolism in COVID-19.

A patient presented to the emergency department with altered mental status and lower extremity weakness in the setting of nitrous oxide inhalant abuse and Coronavirus Disease-2019 (COVID-19) infection. He subsequently developed hypotension and severe hypoxia, found to have a saddle pulmonary embolus (PE) with right heart strain requiring alteplase (tPA).

Bullying among medical and nonmedical students at a university in Eastern Saudi Arabia.

Background: Many medical students, junior doctors, and other health-care professionals have been affected by the negative experience of bullying. Research is scarce on bullying experienced by medical and nonmedical students in Saudi Arabia unlike what is found in Western countries. It is unclear whether being a nonmedical student modifies the risk of being bullied.

Standard precautions and infection control, medical students' knowledge and behavior at a Saudi university: the need for change.

Background: No previous studies have reported the knowledge of Saudi medical students about Standard Precautions (SPs) and infection control.

Objectives: The objectives of this study were to assess medical students' knowledge in clinical years at King Faisal University, Saudi Arabia about SPs' and to explore their attitudes toward the current curricular/training in providing them with effective knowledge and necessary skills with regard to SPs.

Subjects And Methods: This cross sectional study targeted students in clinical stage at College of Medicine, King Faisal University, Saudi Arabia.
