tkDerm touch is a dermatological image database suitable for use by clinical dermatologists. It lets you store and search for your dermatological photos and their metadata in the iPhone and iPad or the database server running PostgreSQL. On how to use it, refer to the tkDerm touch Documentation downloadable from the support page. Taking pictures of patients is an essential part of dermatological practice. Keeping clinical photos in an easily searchable and reusable state is a time-consuming task and many dermatologists have been looking for a tool to store their photos in such a way as to support clinical practice efficiently. tkDerm touch was created to fulfill the dermatologists' need. Features of tkDerm touch include: You can use the local sandbox of the iPhone or iPad as the data and photo storage. Additionally, you can set up the server and use tkDerm touch as a client. You can use your favorite digital cameras in addition to the internal camera of the iPhone or iPad. It maps data to photos automatically based on the time stamps of digital photos. You can find photos you want rapidly by browsing data in alphabetical order of patients' names or diagnoses or in order by the time of shooting or accessing photos. You can find photos by the distribution of an eruption as a search key. It takes you less time to shoot photos for following up a patient by reusing the patient's data you saved at the previous visit. Enjoying the benefits of the handiness of the iPhone or iPad, you can recognize a subtle change of an eruption from the previous visit by side_by_side comparison between a present eruption and the photo displayed on the device. Double-tapping a portion of a photo will enlarge it in such a way that the portion you tapped will be near the center of the enlarged image, which enables you to see details of an eruption easily. By pinching, you can change the size of photos being shown as you like.
