Trestle's Internet-Enabled Microscope Selected by Canadian Health Provider; West Parry Sound Health Centre Deploys Trestle's Solution in Network-wide Evaluation.

IRVINE, Calif. -- Trestle Holdings Inc. (OTCBB:TLHO), a supplier of digital imaging and telemedicine applications, today announced that West Parry Sound Health Centre (WPSHC), a network of healthcare facilities covering 70,000 people throughout Parry Sound, Muskoka and surrounding communities in Ontario, has deployed its first Trestle internet microscopy solution. The system, Trestle's MedMicro, uses standard PCs to connect microscopes to the internet, enabling users to view and navigate slides remotely -- for real-time, accurate consultation and diagnosis.

Like many healthcare networks with disparate facilities spread over large geographic areas, WPSHC has traditionally used couriers to transport patients' slides to appropriate specialists to obtain the best diagnostic results. But, according to Dr. Ola Kassim, WPSHC's chief pathologist and director of laboratory medicine, this method has several flaws that undermine the network's ability to provide the best healthcare. "As a pathologist, I receive specimens from laboratories in our network via physical messenger," explains Dr. Kassim. "This process often takes 24 hours or more -- not an acceptable timeframe if we're dealing with an urgent diagnosis. With Trestle's robotic-microscope technology, we've connected all of the facilities and specialists in our network. My lab in Elliot Lake, for example, can place a specimen on their facility's microscope, and I can go online and view and navigate that slide from my own PC. This cuts my diagnosis time from hours or days to minutes."

According to Dr. Kassim, Trestle's solutions solve another major flaw in traditional telepathology. "When a doctor sends me a photo of a specimen, I am not able to see nearly the detail that I would with the actual slide," says Dr. Kassim. "When viewing a specimen, a pathologist often needs to move the slide, zoom in or out and illuminate certain areas. With a photo, or a static digital image, none of this is possible. But with Trestle, we are able to remotely control an actual slide on an actual microscope in another facility from our own computers -- and even share control of a slide during a consultation between doctors or pathologists in different facilities. The value this adds to our ability to pool our network-wide expertise -- instantly sending a possible breast-cancer sample to a pathologist who deals exclusively with breast cancer, for example -- is immeasurable."

Trestle's solution will further add value to WPSHC's network by cutting costs. As Dr. Kassim explains, when he travels or is not onsite at his West Parry Sound laboratory, the staff will often need to bring in another pathologist -- at a cost of $1,500 to $1,800 per day -- to be on call for emergencies. With Dr. Kassim now able to view and navigate slides remotely via his laptop, Trestle's solution will save the organization these costs.

With its first Trestle MedMicro application successfully deployed - "The system is already improving our diagnostic processes," says Dr. Kassim - West Parry Sound is now evaluating an expansion of Trestle solutions throughout its network.

"Trestle's telepathology solutions deliver convenience and improved healthcare capabilities to physicians and pathologists around the world," said Maurizio Vecchione, Trestle's CEO. "We look forward to expanding the West Parry Sound Project so that Dr. Kassim can collaborate with an expanded group of experts."
