Obtaining a screening chest CT for thoracic aortic injury poses a higher risk of cancer than the likelihood of identifying an aortic injury in injured children.

Taking care of children with mild traumatic brain injury is not easy. This guideline states clearly, based on compiled evidence, what you should and should not do.  It’s helpful.

Clinical clearance of the c-spine missed an equal number of c-spine injuries on CT (10-13%) whether distracting injury (DI) was present or not.

The CHIP rule performed better than other head injury rules in patients >16 years old in striking the balance between avoiding CT in 21% of patients while missing only 2 potential neurosurgical lesions on CT.

In this systematic review and meta-analysis, no single aspect of the physical examination, imaging, or LRINEC score had high enough sensitivity to exclude necrotizing soft tissue infections. Contrast CT performed the best, but it was only 94.3% sensitive at best. If you have a high clinical suspicion, early surgical consultation is necessary for definitive diagnosis and management.

In this retrospective review, age-adjusted, clinical probability-adjusted, and standard D-dimer approaches had similar NPVs (99.7%, 99.1%, 100% respectively). Clinical probability-adjusted D-dimer has potential to exclude PE in more patients without imaging, but use caution before applying this to practice until prospectively validated.

CT and MRI had similar diagnostic accuracy for acute appendicitis and may be used interchangeably.

Incidence of intracerebral hemorrhage (ICH) on CT following minor head trauma in anticoagulated patients was 9%, which means we have to CT all these people.

Head ultrasound (HUS) via open fontanelle was a poor screening tool for intracranial bleed due to accidental or inflicted trauma.

CATCH2 is the CATCH rule plus ≥4 episodes of vomiting.  It was highly sensitive for neurosurgical intervention and predicting injury on CT.
