Binary world/bivalent logic

It cannot be denied that the change from analog to digital technology had an enormous effect on how we communicate in daily life. For somebody who grew up within the last 20 years it is difficult to imagine a world without cell phones, email, or online communities. The digital revolution has not only changed our daily life, it also had a significant impact on the way we share information in medicine. We can share a huge amount of data conveniently and rapidly across vast distances. Modern communication technologies eliminate distance barriers and permit the providing of health care from a distance (telemedicine). Teledermatopathology, using digital pathology images (virtual microscopy), has been successfully launched for diagnosis, education, and research. However, the digital slide scanners that are required for virtual microscopy are expensive, and transmission of large digital images requires highspeed Internet connections. Ironically persons with limited access to expert dermatopathology services will benefit the most from telemedical applications but can afford it the least. The study by Riedl et al in this issue of Dermatology Practical and Conceptual explores the diagnostic accuracy of interactive teledermatopathology [1]. Their method does not require that a dermatopathologist have physical “hands-on” involvement but provides real-time interactions between a technician and a dermatopathologist or between two dermatopathologists. It is an inexpensive and easy way to bring expert opinion to remote places either for education or for diagnosis (for example, to obtain a second opinion). Apropos diagnosis
