Our objective was to assess the utility of PET-CT in five pediatric patients with Langerhans cell histiocytosis (LCH) who underwent PET-CT imaging for clinical staging and determination of lesion activity at various stages of treatment and follow-up. PET-CT combines the anatomic detail of CT and the physiologic activity of (18)F-FDG imaging. We conclude that PET-CT information is clinically useful to evaluate disease activity and response to therapy and provides information that cannot be obtained from technetium 99m methylene diphosphonate bone scans or radiographs.

We present a sleeve fracture at the superior pole of the patella in a 12-year-old boy. Sleeve fractures at the inferior pole of the patella have been well described in the orthopedic and radiologic literature. However, a similar injury at the superior pole of the patella is relatively rare. We hope that awareness of this unusual injury and its imaging findings will allow timely diagnosis and intervention.

Comparative StudySedation with nitrous oxide compared with no sedation during catheterization for urologic imaging in children.
Various strategies to mitigate children's distress during voiding cystourethrography (VCUG) have been described. Sedation with nitrous oxide is comparable to that with oral midazolam for VCUG, but a side-by-side comparison of nitrous oxide sedation and routine care is lacking. ⋯ Sedation with nitrous oxide is effective in reducing distress and pain during catheterization for VCUG or RNC in children.
