Pediatric Appendicitis: CT or Ultrasound?

Appendicitis is the most common pediatric surgical emergency accounting for 5% of urgent pediatric outpatient visits for abdominal pain. Computed tomography (CT) and ultrasonography (US) are two imaging modalities used in the diagnostic evaluation of acute pediatric appendicitis. Both have decreased the incidence of negative appendectomy results. It is well known that CT has greater diagnostic accuracy than US for diagnosing acute appendicitis, but there is concern over long-term cancer risk, with routine use of CT in children.

What modality should be used for pediatric patients who are suspected of appendicitis?

Transient Synovitis vs Septic Arthritis of the Hip

Limping is a common reason for parents to bring their children to emergency departments. It is known that 77% of acute, atraumatic limp is dealt with in the ED, and 20% do not even complain of pain.1 Our job as physicians is to complete appropriate assessments to not miss any serious pathology. Specifically, differentiating between transient synovitis (TS) and septic arthritis (SA) of the hip can be difficult and frustrating for everyone. What is your approach?

Interpret this data how you will: Exposure to 2-3 CT scans of the head will triple the risk of brain tumors; 5-10 head CT scans will triple the risk of leukemia. In absolute terms, this translates into approximately 1 excess case of leukemia and 1 excess brain tumor per 10,000 patients.
