Are antibodies against calsequestrin and type XIII collagen good markers for chronic upper eyelid retraction?
These findings support the notion that autoimmune attack against calsequestrin and collagen XIII in the levator palpebrae superioris (LPS) muscle may play a role in the pathogenesis of upper eyelid retraction and that lid retraction may be the dominant feature of ophthalmopathy in patients with Hashimoto's thyroiditis and non-autoimmune thyroid disease. Because calsequestrin is an intracellular protein, the corresponding autoantibodies probably do not initiate LPS muscle inflammation but may contribute to its damage. The mix of antibodies against calsequestrin and collagen XIII may shed light on the diverse presentations found in thyroid-associated ophthalmopathy.
Admission to a Magnet-designated hospital is associated with a 20% reduction in mortality. We believe that the Magnet program's attention to nursing competence has important consequences for trauma patients, as reflected in the improved survival rates in trauma patients admitted to Magnet-designated hospitals.
