purpose: this study evaluated the effect of donor and eye bank characteristics on graft rating and clinical outcomes after penetrating keratoplasty (pk) in keratoconus-affected patients. methods: a total of 252 consecutive keratoconic eyes that underwent pk were reviewed in this retrospective interventional case series. donor data included age and sex, cause of death, death-to-preservation time...

background and aims. localized gingival recession presents as a special therapeutic problem. subjective parameters and donor site morbidity are often overlooked while deciding on any treatment option. materials and methods. 22 subjects were equally divided in group a (lateral pedicle graft) and group b (free mucosal graft). subjective evaluation of post operative sensitivity, discomfort and ble...

deep anterior lamellar keratoplasty (dalk) has recently been introduced as an alternative procedure to penetrating keratoplasty (pk) for corneal pathologies not affecting the corneal endothelium. dalk does not rely on donor endothelium and requires less rigid criteria for donor corneal tissue quality. therefore, dalk makes it possible to use donor corneas deemed unsuitable for pk. furthermore, ...

background split- thickness skin graft is one of the most common operations in plastic surgery. it is always painful and patient discomfort from donor site often is more significant than recipient site. there is not still a standard method for treatment of the donor site. the purpose of this study was to determine the best method of dressing the donor site among three different methods with res...

PURPOSE To evaluate the effect of donor and eye bank characteristics on graft rating and clinical outcomes after penetrating keratoplasty (PK) for keratoconus. METHODS This retrospective interventional case series included 252 keratoconic eyes which underwent PK. Donor data included age and sex, cause of death, death-to-preservation time, preservation-to-surgery time, epithelial and stromal s...

purpose: to evaluate the influence of donor characteristics (age, death-to-preservation time, preservation-to-surgery time, graft rating, and endothelial cell features) on clinical outcomes following deep anterior lamellar keratoplasty (dalk) in patients with keratoconus. methods: in this retrospective study, 290 consecutive keratoconic eyes underwent dalk using donor corneas of different quali...

closure of donor site of the flap has special problems. reduction of this site will decrease the morbidity of operation. in this study, we present our experience in donor site size reduction. methods between 2006 and 2008, 15 patients with skin and soft tissue defects underwent operation. in all patients, coverage of defect was performed with various flaps. substratum horizontal mat-tress sutur...

advances in nephrology and pediatric urology have increased the number of children who survive renal disease and become candidates for renal transplantation. ten years of experience in pediatric renal transplantation are reviewed to determine the rates of patient morbidity and graft survival. of the 450 renal transplantations performed in imam reza hospital (1989- 1999), fifty-one were done on ...

purpose: to report the possible transmission of zygomycetes infection by a corneal graft harvested from a donor with signs of trauma to the orbital region to a keratoconic patient who underwent deep anterior lamellar keratoplasty (dalk). case report: a 19-year-old keratoconic man underwent dalk in the right eye. the corneal graft was harvested from a donor with signs of orbital trauma. on posto...

background: delayed graft function is a main complication after deceased donor kidney transplantation that adversely affects graft outcome. difficulties in prediction and early detection of delayed graft function have hindered the ability to perform proper therapeutic interventions. we investigated whether measuring urinary interleukin 18 and neutrophil gelatinase-associated lipocalin as marker...
