Clinical Studies Support the Use of Longport's Technology.

GLEN MILLS, Pa. -- Longport, Inc. (OTC PK: LPTI), a medical technology specialist in high-frequency, high-resolution ultrasound imaging, today announced that two papers have recently been published in peer-reviewed journals that report on the utilization of Longport's EPISCAN system.

The first paper, published in the November/December 2006 issue of Advances in Skin & Wound Care, presents the use of Longport's EPISCAN for imaging the pathology of early-stage pressure ulcers and the utility of high-resolution ultrasound in the early detection of this condition.

This paper concludes, "A better understanding of the pathogenesis of pressure ulcers through the use of high-resolution ultrasound to detect soft tissue damage and edema before visible clinical signs could lead to earlier and more focused pressure ulcer prevention programs, resulting in reduced pain and suffering for improved patient quality of life and wound care cost savings."

The full reference to this paper is: Use of High-Resolution, High-Frequency Diagnostic Ultrasound to Investigate the Pathogenesis of Pressure Ulcer Development. Advances in Skin & Wound Care. 19(9):498-505, November/December 2006.

The second paper, published in the Tissue Viability Supplement of the British Journal of Nursing, reports on a case study using high-resolution ultrasound to assess chronic wounds. One of the key points of this paper is, "High-frequency ultrasound could be used to image and quantify changes in the wounds as a means of non-invasively visualizing wound characteristics which would otherwise be missed using standard visual assessments alone."

"These studies contribute to the validation of our technology essential for the documentation of positive clinical outcomes, clinical acceptance and clinical use," said Connie Phillips-Jones, RN, MSN Longport's Director of Clinical Support.
