There was a toddler with swollen thumbs who kept coming in to the pediatric clinic where Dr. Ann Botash was working. She and the other doctors wondered if he had a joint problem
or an immune disease that could be causing his painful puffy thumbs and
vomiting.
Then the child returned to Upstate University Hospital in a coma. It turned out his mother's boyfriend had been hanging the boy by his thumbs. Then the man used the child as a punching bag, which was causing the vomiting. The doctors discovered the abuse only because the boyfriend confessed, Botash said.
