Cranioectodermal dysplasia (CED) is an infrequently described autosomal recessive disorder characterized by craniofacial, ectodermal and skeletal abnormalities, and associated with increased risk of chronic renal failure. A degree of joint laxity has been noted in some CED patients, but significant skin and soft-tissue laxity has not previously been highlighted as ...

Clinical findings and blood parameters often are inconclusive in patients with periprosthetic joint infections. Among the accepted criteria for diagnosis, histologic analysis of debrided tissue can detect infection in most cases but does not allow intraoperative decision making. We evaluated the validity of intraoperative frozen sections for detection of prosthetic ...
