Trestle Expands Internet-Microscopy Offerings to Mexico

ABC Hospital, a Leading Private Hospital in Mexico, Selects MedMicro to Enable Its Pathologists to Work Together Remotely

Trestle Holdings Inc. , a supplier of digital imaging and telemedicine applications, today announced that The American British Cowdray Medical Center, one of the largest and most prestigious private hospitals in Mexico, has installed Trestle's Internet-microscopy solution in its facilities as part of the organization's expansion to new locations.

Founded in 1941 by the merger of two large hospitals in Mexico, the nonprofit ABC Medical Center has built an international reputation for offering superior healthcare. In late 2004, ABC expanded to a new campus in the popular suburban area of Santa Fe, which the organization heralded as the "most advanced medical facility in Latin America."

After reviewing several digital-imaging solutions for its laboratories, ABC Hospital chose Trestle's MedMicro. This web-based slide-viewing system enables medical personnel to view high-quality digital images of patients' specimens from anywhere, via the Internet, with a standard PC. Physicians in different locations can view a patient's slide simultaneously and collaborate in real-time.

According to Dr. Carlos Ortiz, director of pathology at The American British Cowdray Hospital, "The Trestle MedMicro system will provide immediate interactive consultation regarding surgical pathology specimens. This will result in more efficient collaboration between the hospitals and improved healthcare for patients."

"With healthcare networks adding locations to serve remote areas and contracting services out to multiple facilities, we believe there is a growing need for these providers to ensure their geographical expansion doesn't negatively affect their healthcare," said Maurizio Vecchione, Trestle's chief executive officer. "Trestle's solutions help overcome this by enabling a network for virtual consultation, regardless of the location of expert pathologists. Being selected by ABC Hospital -- a medical center that prides itself on providing the highest level of medical service -- is a great affirmation of the benefits of Trestle's products."

ABC Medical Center purchased Trestle's MedMicro through Ad Astra International Inc., a distributor of tele-health solutions for healthcare providers. Trestle maintains a non-exclusive sales-agent relationship with AAII, which operates throughout Mexico and Central America.
