Predicting mortality in geriatric patients with fever in the emergency departments: a prospective validation study.

Objective: Emergency physicians are always faced with the challenge of choosing the appropriate disposition for elderly patients in order to ensure an acceptable care plan and effective use of resources. A clinical decision rule, Geriatric Fever Score (GFS) has been proposed but not validated to help ED physicians with decision-making. This rule employs leukocytosis, severe coma, and thrombocytopenia as predictors of 30-day mortality.

External validation of the bedside score for the diagnosis of acute cholecystitis.

Unlabelled: Objective: Acute cholecystitis usually presents with right upper quadrant (RUQ) abdominal pain. However, there are other conditions with similar findings which make the diagnosis difficult. The objective of this study is to prospectively validate the performance of the bedside score for the diagnosis of cholecystitis in patients presenting to the emergency department (ED) with possible acute cholecystitis.

The return visit, outcome and predicting factors of return visit among suspected COVID-19 outpatients.

Rate of return visit, predicting factors of return visit and occurrence of adverse events in suspected to be or likely cases of COVID-19 patients who received outpatient treatment. This is a retrospective observational cohort study on patients (> 16 years), suspected to be or likely cases of COVID-19 who were visited in a respiratory emergency department and subsequently discharged home. Patients' baseline characteristics were extracted from medical charts.

The efficacy of intravenous lidocaine and its side effects in comparison with intravenous morphine sulfate in patients admitted to the ED with right upper abdominal pain suspected of biliary colic.

Background: Intravenous (IV) Lidocaine can be used as analgesic in acute pain management in the emergency department (ED).

Objective: Efficacy of IV Lidocaine in comparison with IV morphine in acute pain management in the ED.

Method: This is a double-blind randomized clinical trial on adult (18-64 year) patients with right upper abdominal pain suspected of biliary colic who needed pain management.

Intranasal ketamine reduces pain of digital nerve block; a double blind randomized clinical trial.

Background: Low dose ketamine can be used as analgesic in acute pain management in the emergency department (ED).

Objective: Efficacy of IN ketamine in acute pain management in the ED.

Method: This is a double blind randomized clinical trial on patients older than 15 years who needed digital nerve block (DNB).

Atypical Presentation of Acute Appendicitis: A 32-year-old Man with Gastroenteritis Symptoms; an Educational Case.

Introduction: Appendicitis is a common condition that almost always requires emergency surgery. The diagnosis is clear when the patient presents with classic symptoms. However, presentation may be variable due to variations in the position and length of the appendix.

Jejunal Perforation Following Blunt Abdominal Trauma; a Case Report.

Introduction: The possibility of intestinal injury for all patients presenting to emergency department (ED) with blunt abdominal trauma, despite minimal physical signs should be considered. To highlight the patient management, hear, we report a case of hollow viscus injuries resulting from blunt abdominal trauma referring to a teaching hospital in Tehran, Iran.

Case Presentation: A 30-year-old man presented to the ED after "falling into a hole" with his back and had direct blunt abdominal trauma by a heavy bag of cement.
