The ultrasonographic version of the Greulich-Pyle atlas can be used to estimate bone age even in ultrasonography departments. This method is highly correlated and a valid alternative to plain radiography for bone age estimation. This enables estimation of skeletal age in ultrasonography departments easily without exposing the patient to radiation.

The retrobulbar circulation and flow hemodynamics in the left VA may be altered in both headache and headache-free periods in migraineurs without aura. The differences found between migraineurs and control subjects may implicate autonomic dysfunction in migraineurs.

Tumor biopsy is rarely performed in diffuse intrinsic pontine glioma (DIPG) due to the presumed risk of surgical complications, although data on the surgery related morbidity of DIPG biopsy is sparse. We performed a retrospective review on 22 consecutive cases of DIPG diagnosed from 2002 to 2012 at Children's Hospital of Michigan, 15 of which underwent biopsy. Transient new or worsening neurological deficits were observed in three of 15 cases following surgery. No surgery related mortality or permanent deficit was observed, and the mean overall survival was 10.4 ± 3.8 months. Undergoing biopsy did not adversely affect the outcome.
