[Hospital emergency room diagnosis of acute appendicitis in patients aged 2 to 20 years: the INFURG-SEMES score from the emergency infections study of the Spanish Society of Emergency Medicine].

Objectives: To develop the INFURG-SEMES scale (based on the emergency infections study of the Spanish Society of Emergency Medicine) using clinical and laboratory data to diagnose acute appendicitis (AA) in patients aged 2 to 20 years who were evaluated in hospital emergency departments and to compare its diagnostic yield to that of the Alvarado score.

Material And Methods: Prospective observational cohort study enrolling consecutive patients between the ages of 2 and 20 years who came to 4 hospital emergency departments with abdominal pain suggestive of AA and of less than 72 hours' duration. We collected demographic, clinical, analytic (white blood cell count, differential counts, and C-reactive protein [CRP] levels), and radiographic data (ultrasound and/or computed tomography scans).

Diagnostic accuracy of the APPY1 Test in patients aged 2-20 years with suspected acute appendicitis presenting to emergency departments.

Objective: Evaluate the diagnostic accuracy of the APPY1 Test alone and in combination with the Alvarado score (AS) to rule out acute appendicitis (AA) in patients presenting to EDs with abdominal pain suspicious for AA.

Methodology: Observational study in a prospective consecutive cohort including all patients from 2 to 20 years with abdominal pain suggestive of AA in four EDs. The APPY1 Test was performed and AS was calculated to determine risk stratification for each patient.

Effective coil embolization of intracavernous carotid artery pseudoaneurysm with parental artery preservation following severe head trauma in a pediatric patient.

Background: Intracranial traumatic pseudoaneurysms are rare in children. If left untreated, mortality rate can be as high as 50% due to delayed rupture and disastrous bleeding. Endovascular embolization is considered the preferred treatment option because of its minimal invasiveness and negligible mortality.
