Limbal conjunctival autograft in a subacute alkaline corneal burn.

Persistent epithelial defects are a common complication after severe alkaline corneal burns. Chemical damage to the limbal area destroys the stem cells that play a key role in corneal reepithelialization. Limbal conjunctival autograft transplantation has been proposed as a treatment to replace damaged limbal stem cells and promote epithelial healing.

Quantitative measurement of wound spreading in radial keratotomy.

Background: Many studies of radial keratotomy have been performed, however quantitative laboratory evaluation of the biomechanics of this procedure is still incomplete. Furthermore, most measurements of strain in the past have utilized strip testing, thus destroying the normal physiological structure and water balance of the cornea.

Methods: We report on a membrane inflation method of wound spreading in intact human corneas using the Baribeau Micronscope.

Surgical treatment of the parathyroid gland in patients with end-stage renal disease.

During the period from December 1984 to December 1986, ten patients with end-stage renal disease were evaluated with hyperparathyroidism refractory to medical management. Symptoms were bone pain in eight patients and pruritus and constipation in two. Two patients with bone pain also had impaired mentation.
