“…Overall, diagnostic accuracy of static image telepathology has been reviewed numerous times in different studies and results range from 68-100%, with improving figures over the years [Della Mea et al, 1996;Weinberg et al, 1996;Halliday et al, 1997;Dunn et al, 1999;Williams et al, 2001;Cross et al, 2002;Nordrum et al, 2004]. Static image telepathology is an accessible technique that can also be used in developing countries.…”

Malignant gonadal germ cell tumors, referred to as germ cell cancers (GCC), occur with increased frequency in individuals who have specific types of differences (disorders) of sex development (DSD). Recent population-based studies have identified new environmental and genetic risk factors that have led to a ‘genvironment' hypothesis, which may potentially be helpful in risk assessment in DSD-related GCC. In DSD, the malignancy risk is highly heterogeneous, but recent studies allow now to discriminate between high- and low-risk conditions. Gonadal biopsy is in some cases the best procedure of choice to assess the risk, and with the availability of immunohistochemical biomarkers [OCT3/4 (POU5F1), TSPY, SOX9, FOXL2 and KITLG (SCF)], a reliable classification of GCC and its precursors can be made. The opportunities in the field of virtual diagnostic pathology will be presented, having possibilities for rare diseases in general and DSD specifically. It is expected that the International DSD Registry will stimulate international collaborations, facilitating better diagnostic procedures as well as research.

Prioritisation of telemedicine services for large scale implementation in Norway

et al. 2007

In late 2005, the Northern Norway Regional Health Authority requested an evaluation of all tested telemedicine services in northern Norway to clarify which were suitable for large scale implementation. A total of 282 reports from the Norwegian Centre for Telemedicine, the University Hospital of North Norway and the University of Tromsø were included in the study. Projects not focusing on secondary health care were excluded and 46 studies representing 21 topics entered the final analysis. They were analysed with a self-developed scoring tool focusing on five items. Eleven topics were concluded as being candidates for large scale implementation and grouped according to priority. The first priority topics were teleradiology, digital communication/integration of patient records and education. The second priority topics were teledialysis, pre-hospital thrombolysis, telepsychiatry and teledermatology. The third priority topics were paediatrics, district medical centres, tele-ophthalmology and tele-otorhinolaryngology. No priority was suggested for the projects in cardiology, endocrinology, geriatrics, gynaecology/obstetrics, pathology and nursing/care. User support, training, research ability, financial incentives and interaction between clinicians and ICT-personnel were considered as important factors in motivating health-care personnel to use telemedicine.

“…Thus, the use of teledermatopathology gains particular acceptance for consultation of other specialists, but also in situations when experts in dermatopathology are not available locally. [12][13][14][15][16] Nevertheless, telemedical diagnostics stands in general for presence of a subgroup of digitally transferrable informations, as all existing data on a patient are only accessible in direct contact with the patient. Furthermore, it is a known fact that in telepathology, especially at higher-power examinations, the image resolution is frequently affected.…”

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.
