Key Normative Data Validating Innovative Reflux System Unveiled at Digestive Disease Week 2007

WASHINGTON, DC -- (MARKET WIRE) -- May 25, 2007 -- Significant data supporting a new technology for measuring acid reflux, the Restech Dx-pH Measurement System™, was presented at Digestive Disease Week (DDW), regarded as the largest international gathering of physicians and researchers in the field of gastroenterology.

Dr. Colleen Gaughan authored the abstract Measurement of Gastroesophageal Reflux in the Pharynx: A New Technology and presented the poster in a session of the American Gastroenterological Association (AGA) on Sunday, May 20th. The study group was headed by world-renowned thoracic surgeon and co-inventor of the standardized Johnson-DeMeester Score, Dr. Tom R. DeMeester of USC's Keck School of Medicine Esophageal Function Laboratory.

The researchers concluded from their preliminary study that "the Restech Dx-upper airway pH Probe provides reliable pH monitoring data in symptomatic patients compared to normal controls. There is a significant pH gradient in the esophagus, related to dilutional effects of saliva."

The study evaluated the pharyngeal pH environment in 20 patients and 10 normal, asymptomatic controls. USC researchers anticipate completion of the study in late 2007, ultimately compiling data from over fifty asymptomatic volunteers.

The presentation indicates successful clinical and scientific validation of an advanced reflux measuring and recording tool for assisting in the diagnosis of supraesophageal reflux. Unlike conventional reflux detection systems, the Restech Dx-System can be used above the esophagus for a more comfortable and reliable patient test. The study data will help clinicians who are using the Dx-System to better diagnose reflux related diseases including asthma and chronic cough.

Emphasizing the impact this device will have on the gastroenterology community, Dr. Gaughan stated, "Physicians can now obtain reliable information without performing manometry -- instead, the Dx-System is easy to place and is well-tolerated by the patient."

Restech is a leader in developing world-class medical technologies assisting physicians in the diagnosis of reflux related health problems. For more information on the Dx-pH Measurement System, please contact Debra Krahel or Bree Fisk at (800) 352-1512 or visit http://www.restech-corp.com.
