Background—Pterygium is a common problem and after surgical removal may recur in up to 80% of cases, depending on the technique of primary excision. Recurrent pterygia can be aggressive and repeated excision may result in severe conjunctival scarring and shortening, resulting in insuYcient conjunctiva to perform further grafting and lid surgery. When there is insuYcient autologous conjunctiva, ...
purpose: to investigate the efficacy of topical cyclosporine a 2% in treating and preventing recurrent graft rejection episodes after penetrating keratoplasty (pkp) in patients with history of previous rejection episodes. methods: in this clinical trial, eligible pkp patients were randomly given topical cyclosporine a 2% or placebo in addition to a standard corticosteroid regimen for an episode...
The applicability of the right internal thoracic artery (RITA) for coronary artery bypass grafting is higher when used as a free graft than as a pedicled graft. However, the technical difficulty of directly connecting the proximal end of the free RITA to the much larger aorta leads to poor patency. To overcome this technical limitation, we have used a modification that places the proximal end o...
PURPOSE The conjunctival epithelium performs an important role in the homeostasis and integrity of the eye. To protect the integrity of the ocular surface, these cells must be replaced from locally concentrated or randomly distributed foci of stem cells. These slow-cycling stem cells produce transient amplifying cells that undergo further divisions before becoming mature conjunctival epithelial...
BACKGROUND Scleromalacia, in the form of scleral thinning, melting, and necrosis, is a potentially serious complication of pterygium excision. This study introduces a new biodegradable material, Ologen™ collagen matrix (OCM), to repair scleral thinning as an alternative to preserved scleral tissue, and evaluates the long-term outcomes of OCM for ocular surface reconstruction surgery. CASE PRE...
PURPOSE The purpose of this study was to compare inflammatory events and graft characteristics 1 month and 6 months after conjunctival limbal autograft (CLAU) with and without intraoperative mitomycin C (MMC). METHODS This study included 69 eyes of 69 patient's eyes with pterygium. Clinical data concerning patient demography, preoperative examination including pterygium morphology, recurrence...
Severe graft-versus-host disease is a major barrier for non-T-cell-depleted haploidentical stem cell transplantation. There is no consensus on the optimal graft-versus-host disease prophylaxis. This study compared the two most commonly used graft-versus-host disease prophylaxis regimens (post-transplant cyclophosphamide-based vs. the anti-thymocyte globulin-based) in adults with acute myeloid l...
