Impact of diabetes and smoking epidemic in the Middle East on the presentation with acute coronary syndrome in very young patients.

We describe the baseline characteristics, management, and outcomes of acute coronary syndrome (ACS) in patients of age ≤ 40 in the Gulf region of the Middle East. We studied 8176 hospitalized patients (≤ 40 years) with ACS. Ten percent (805) of the recruited patients were ≤ 40 years.

Identifying febrile young infants with bacteremia: is the peripheral white blood cell count an accurate screen?

Study Objective: We estimated the accuracy of the total peripheral WBC count as a screen for bacteremia in febrile young infants.

Methods: We evaluated, retrospectively, the performance characteristics of linear and nonlinear (U-shaped) logistic models for predicting bacteremia that are based on the total peripheral WBC count. Research subjects were consecutive 0- to 89-day-old infants who had a temperature in triage of greater than or equal to 38 degrees C (> or =100.
