Recent Development of Computer Vision Technology to Improve Capsule Endoscopy

Capsule endoscopy (CE) is a preferred diagnostic method for analyzing small bowel diseases. However, capsule endoscopes capture a sparse number of images because of their mechanical limitations. Post-procedural management using computational methods can enhance image quality. Additional information, including depth, can be obtained by using recently developed computer vision techniques. It is possible to measure the size of lesions and track the trajectory of capsule endoscopes using the computer vision technology, without requiring additional equipment. Moreover, the computational analysis of CE images can help detect lesions more accurately within a shorter time. Newly introduced deep leaning-based methods have shown more remarkable results over traditional computerized approaches. A large-scale standard dataset should be prepared to develop an optimal algorithms for improving the diagnostic yield of CE. The close collaboration between information technology and medical professionals is needed.

Tarsal Tunnel Syndrome: A Case Report / 대한정형외과학회잡지

Tarsal tunnel syndrom is characterized by pain, paresthesias in the foot in either the entire distribution of the tibial nerve or the distribution of one or two of its major branches and caused by compression of the posterior tibial nerve as it passes posterior and inferior to the medial malleolus. This syndrome is not recognized as readily as its counterpart in the upper extremity, the carpal tunnel syndrome. Anatomically unlike the transv erse carpal ligament the laciniate ligament(flexor retinaculum) has several deep fibrous septa which blend with the periosteum covering the medial side of the calcaneus. The neurovascular bundle in the tarsal tunnel is often attached to some of these septa, rendering itself more liable to minor degrees of traction on movements of the foot. A case of tarsal tunnel syndrome, the patient 24 years old policeman, treated succesfully with surgical release of laciniate ligament is reported.
