Estimated risk of radiation-induced cancer from paediatric chest CT: two-year cohort study.
The increasing absolute number of paediatric CT scans raises concern about the safety and efficacy and the effects of consecutive diagnostic ionising radiation. ⋯ Using dedicated scan protocols, total lifetime attributable risk of cancer incidence and mortality for chest CT is estimated low for paediatric chest CT, being highest for female neonates.

Radiation dose and image quality in pediatric chest CT: effects of iterative reconstruction in normal weight and overweight children.
New CT reconstruction techniques may help reduce the burden of ionizing radiation. ⋯ In both normal weight and overweight children, the ASIR technique is associated with a greater than 57% mean dose reduction, without significantly impacting diagnostic image quality in pediatric chest CT examinations. However, CT scans in overweight children may have a greater noise level, even when using the ASIR technique.

It is estimated that inflicted burn injuries in physically abused children occur with a prevalence of approximately 6-20%. Identification of burns of a nonaccidental nature is oftentimes difficult. Underlying skeletal injuries in abusive environments are often overshadowed by the acute burn injury. ⋯ Intentional burns in children appear to be more common than previously known, occurring in 40% of the children in our series, a greater percentage than has been reported in the literature. In addition, nearly one-third of these children with inflicted burns had associated skeletal injuries, most commonly healing rib fractures. Thus young children with concern for nonaccidental burns should undergo a skeletal survey.

Transient flow response after femoral artery catheterization for diagnostic neuroangiography in infants and children: Doppler US assessment of the ipsilateral femoral artery.
Hemodynamic changes in the distal arteries during transfemoral catheterization in children have not been documented. ⋯ Changes in the spectral waveforms of superficial femoral arteries frequently occur in children during transfemoral cerebral angiography (13/27, 48%). Significant arterial flow disturbance was noted on Doppler US in children with a common femoral artery <1 mm larger than the femoral sheath diameter.
