Presenting May 1 at the Pediatric Academic Societies annual meeting in Vancouver, a team of researchers led by child abuse expert Dr. Rachel Berger at Children's Hospital of Pittsburgh reported a significant increase in cases of shaken baby syndrome, in which youngsters are shaken violently by an adult, since the start of the current recession. Researchers analyzed data on 512 cases of head trauma in the children's centers of four hospitals in Pittsburgh, Cincinnati, Columbus and Seattle, and found that the number of cases had increased to 9.3 cases per month since Dec. 1, 2007, compared with 6 cases per month prior to that date — a rate that had held steady since 2004.
