Acromial stress fracture in a young wheelchair user with Charcot-Marie-Tooth disease: a case report

Acromial stress fractures are rare and have not been highlighted as a potential complication of wheelchair use. We report the case of a 22-year old female wheelchair bound patient with Charcot-Marie-Tooth disease who presented with a four-year history of shoulder pain which impaired mobility and quality of life. Plain radiographs showed a cortical irregularity of the acromion but no double-density sign. After CT scans a non-united acromial stress fracture was diagnosed. She had no other shoulder pathology. The new technique of using a superiorly closing wedge osteotomy with cancellous lag screw fixation was successful in correcting the mobile non-united acromial fragment and resolving her pain

The effect of aging on facial prototype formation

Young and elderly subjects performed a recognition task on unfamiliar faces which were variations of a non-inspected prototype (procedure designed by Solso and McCarthy, 1981a). The test was taken immediately or six weeks later. Young subjects (n = 32) clearly replicated the performance of the Solso and McCarthy subjects, namely, very confident (false) recognition of the prototype and correct rejection of new stimuli in accordance with their similarity to the prototype. In addition, the results showed a strong analogy between elderly and young subjects. In particular, elderly subjects (n = 32) abstracted the never-seen prototype as well as younger subjects, even after six weeks. However, they were significantly less confident in rejecting new items
