- Abstract
Telepathology is the practice of diagnostic histopathology performed on digital pictures. In this study, we focused on the technical requirements for achievement of a correct diagnosis on digital histopathologic images. A collection of 560 melanocytic lesions was selected from the files of the Department of Dermatology, Medical University of Graz, Austria. From each lesion one histologic slide was completely digitally scanned with a robotic microscope. Digital pictures were reviewed by 4 dermatopathologists using a presentation program, which recorded the number of image calls, applied magnifications, overall time needed, and amount of transmitted bits during the digital sign-out. One month later, the 4 microscopists had to review the corresponding slides and render a direct diagnosis on each case. Telepathologic diagnoses corresponded with the original diagnoses in a range from 90.4% to 96.4% of cases (kappa 0.80 to 0.93; P < 0.001). The median time needed for achievement of a diagnosis was 22 seconds and was significantly higher for melanomas compared with nevi. The median transmission effort for each diagnosis was 510 kilobytes after JPEG compression. Using an ISDN line with a transmission capacity of 64 kilobits/ second, this correlates to a transmission time of about 1 minute. Our results demonstrate that correct reporting on digital histopathologic images is possible with only a little time exposure. For an adequately fast transmission ISDN lines are suffcient after JPEG compression.

A non-commercial teledermatology network based on store-and-forward operation was established in April 2002. The aim was to create an easy-to-use platform for teleconsultation services, where physicians could seek diagnostic advice in dermatology from a pool of expert consultants and where they could present and discuss challenging dermatology cases with special emphasis on diagnosis and therapy. An online moderated discussion forum was added in October 2003. During the first two years, 348 health-care professionals from 45 countries registered to use the Website. A total of 783 requests for consultations were answered; 285 requests concerned pigmented skin lesions, 440 requests were from the whole range of clinical dermatology and 58 requests were about non-melanoma skin cancer. Of a total of 133 requests analysed, 80 (60%) were answered within one day, 47 (35%) within one week, five (4%) within two weeks and one (1%) consultation was answered in more than two weeks. Our experience with a discretionary, non-commercial, multilingual Website for open-access teleconsulting in dermatology appears to be successful. The Website represents an example of user-generated content, together with active interaction between users, who can present and discuss cases with remote colleagues. [ABSTRACT FROM AUTHOR]

We investigated the feasibility and diagnostic agreement of a virtual slide system (VSS) in teledermatopathology. Forty-six biopsy specimens from inflammatory skin diseases were selected and scanned with a VSS at the Research Unit of Teledermatology, Medical University of Graz, Graz, Austria. Images were stored oil a virtual slide server on which a specific Web application suited for telepathology (http://telederm.org/research/dermatopath/) runs. Twelve teleconsultants from 6 different Countries reviewed the 46 cases, working directly oil the Web application. Telediagnoses agreed with gold standard and conventional diagnosis with an average of 73% and 74%, respectively. Complete concordance among all teleconsultants with gold standard and conventional diagnosis was found in 20% of the cases. In 10 cases in which complete clinical data were missing, the average agreement of telediagnosis with gold standard diagnosis and conventional diagnosis decreased to 65% and 66%, respectively. Only 3 of 4 cases of inflammatory skin diseases were correctly diagnosed remotely with VSS. The system that we have used, despite its usability, is not completely feasible for teledermatopathology of inflammatory skin disease. Moreover, the performance seems to have been influenced by the availability of complete clinical data and by the intrinsic difficulty of the pathology of inflammatory skin diseases.
