Percutaneous retrieval of intravascular venous foreign bodies in children.
The use of vascular lines both venous and arterial in children has significantly increased in the last decade with the potential risk that an intravascular device may become an intravascular foreign body. Percutaneous retrieval by interventional radiology has become an accepted method of foreign body removal. ⋯ Percutaneous intravascular foreign body retrieval by interventional radiologists is a safe and effective method of retrieving embolized fragments from venous access devices in pediatric patients.

ReviewCompendium of national guidelines for imaging of the pediatric patient.
Diagnostic imaging plays an integral role in diagnosing and managing many pediatric disorders, but there is growing concern in both the medical community and the general public about the long-term health effects of ionizing radiation in children, as well as utilization of imaging evaluation. These concerns, coupled with increasing pressure to reduce national health care spending, underscore the need for an assessment of readily available guidelines, especially evidence-based guidelines, for imaging in children. ⋯ The compendium generated in this study can be used to direct clinical care, inform policy development and improve education of health care personnel. Additionally, the compendium can be used to identify areas of redundancy or deficiency, which may stimulate the reassessment of existing recommendations as well as the creation of new guidelines.

Case Reports'Benign' ovarian teratoma and N-methyl-D-aspartate receptor (NMDAR) encephalitis in a child.
N-methyl-D-aspartate receptor (NMDAR) encephalitis is a life-threatening paraneoplastic neuropsychiatric encephalitis that predominantly affects young women and has a strong association with ovarian teratomas. Removal of the ovarian teratomas improves the prognosis and decreases the risk of recurrence. We present an 11-year-old girl with NMDAR encephalitis with small bilateral teratomas not initially appreciated on abdominal CT or pelvic MRI. ⋯ In NMDAR encephalitis, the ovarian teratomas can be very small, particularly in children, and easily missed on cross-sectional imaging. Awareness of the association of NMDAR encephalitis and ovarian teratomas will improve the diagnostic accuracy and imaging interpretation. Periodic sonography and MRI might be warranted in children if the initial study is negative.
