Choo Becomes Division Director

After more than 37 years in the role, Robin Cotton, MD, stepped down as Division Director in 2012. Cotton built the Division into the world's premier center for diagnosing and treating  airway abnormalities. The Division has grown into one of the nation’s busiest otolaryngology practices, with more than 33,000 outpatient visits and more than 11,000 procedures performed a year. After an exhaustive national search, Daniel Choo, MD, was named Cotton’s successor in October 2012.

Cotton Receives William Cooper Procter Medallion

In February 2013, Robin Cotton, MD, became only the ninth scientist since 1960 to be awarded the William Cooper Procter Medallion, the highest award bestowed by the Cincinnati Children’s Board of Trustees. Tom Cody, chairman of the board, called Cotton “a remarkable innovator, surgeon, educator and leader...”

Breakthrough Study in Usher Syndrome

Saima Riazuddin, PhD, and colleagues published a study entitled "Alterations of the CIB2 calcium- and integrin-binding protein, cause Usher syndrome type 1J and nonsyndromic deafness DFNB48” in Nature Genetics. This breakthrough work also was featured in the Editor’s Choice of Science Journal.

Nature Genetics. 2012. 44:1265-71.

Several genes associated with different types of Usher syndrome have been identified. Most of these genes encode common structural and motor proteins that build sensory cells in the eye and inner ear. However, the gene reported in our paper, CIB2, which encodes a calcium and integrin binding protein, is believed to play a functional role in mechanoelectrical transduction, the process of converting sound energy into an electrical signal that the brain recognized as sound.

Our studies suggest that CIB2 might be important in maintaining calcium level in the sensory cells. Given that there are many cardiac ischemia and hypertension drugs that work by affecting calcium handling in the muscle cells, it is possible that one day a similar drug may be used to target a type of Usher syndrome that we described in our study
