Dr. Rachakonda at the CORE Research Awards ceremony with Larry Lustig, MD

October 2011 – Tara Rachakonda, MD of Washington University School of Medicine, St. Louis, is working on developing a unique hearing-related quality of life assessment for adolescents with hearing loss, the Hearing Environments and Reflection on Quality of Life Questionnaire, or the HEAR-QL. Dr. Rachakonda is the 2011-2012 recipient of the American Hearing Research Foundation Wiley H. Harrison Memorial Research Grant.

 The rate of hearing loss in adolescents has increased over the past decade.  Currently there are no hearing-related quality of life (QOL) assessments tailored for adolescents. Having an adolescent-specific QOL…

Meniere’s disease is a balance disorder characterized by mild to intense episodes of dizziness, where in the worst cases, standing and walking become impossible and the associated nausea can be completely debilitating. The attacks are believed to be cause by tears or other insults to the membranes of the vestibular tissues.

Q: When did your hearing loss first start and how did it present itself?
A: In 1957, I was twenty-one at the time. The first symptom was a severe loss of balance followed by loss of hearing. To this day, I have very little inner ear vestibular function and compensate with my eyes. I also experienced inflammation of my eyes, fortunately, that cleared up.

Q: How was a diagnosis made and what kinds of doctors did you see?
A: A hospital…

One of the challenges in hair cell research is the difficulty in harvesting enough hair cells to perform molecular experiments. An inner ear may have only 10-30,000 hair cells, so thousands of animals – typically mice, which are also very expensive to maintain – may be needed to collect enough hair cells for experiments. Additionally, inner ears are tiny and very hard to dissect in order to get at the various tissues. “This…

Dr. Shim is interested in how the three-dimensional structure of the inner ear is formed during embryonic development and how the sensory regions of the inner ear epithelium are patterned.

Dr. Shim takes a molecular and genetic approach to understanding inner ear development in the mouse, and current work is focused on understanding the role of the Sprouty family of receptor tyrosine kinase antagonists in inner ear development and function. In particular, Dr. Shim found that Sprouty2 mutant mice are born with severe hearing impairment associated with a postnatal cell fate…

New Diagnostic Tool Can Rapidly Identify Children with Learning Disabilities Caused by Problems in Sound Processing

January, 2007 — A new, easy-to-use diagnostic tool that can quickly identify a sizeable subset of learning disabled children is now commercially available.

That’s good news for youngsters aged 8 to 12 who, once identified, can receive auditory training that can improve their academic learning.

"Learning disabilities are believed to affect nearly one in 10 children, but their causes are difficult to pinpoint," says Nina Kraus, director of Northwestern University’s Auditory Neuroscience Laboratory. She and Northwestern researchers Trent Nicol and Steven Zecker have found that…
