introduction: coverage of bone grafts is very important in reconstructive surgery. in edentulous alveolar ridges this coverage is particularly important for supporting dental prostheses. here we present the case of a patient with a large deficient maxillary anterior region that was reconstructed with a bilateral palatal submucosal periosteal connective tissue flap: a soft tissue reserve for upp...

background: lactic acidosis in cardiac surgical patients is a manifestation of systemic inflammation and excess pro-inflammatory cytokine production. this investigation was designed to integrate basic concepts about lactate acidosis with a clinically used of serum lactate in patients under coronary artery bypass surgery (cabg) by on pump method. methods: from august to september 2012, 15 patien...

patients and methods we investigated the timing and frequency of acute rejection episodes related to long-term patient-graft survival in taleghani hospital between 1990 and 2011. recipients were divided into three groups as group-1 (no rejection), group-2 (early acute rejection [ear]: less than 3-months) and group-3 (late acute rejection [lar]: after 3 months of transplant). conclusions lar had...

background the human leukocyte antigen (hla) system is widely used as a strategy in the search for the etiology of renal function impairment. objectives this study was carried out to detect the most common hla alleles’ distribution in kidney transplant in both donors and recipients, and clarify the association between hla alleles and renal dysfunction immediately after transplantation. patients...

recalcitrant gingival erythematous lichen planus lesions comprise a considerable therapeutic problem. this case of chronic desquamative gingivitis in a 25-year-old woman with erosive oral lichen planus was treated with topical and systemic corticosteroid administration, followed by placement of a free gingival graft on right upper quadrant. although recurrence of the lesions was observed follow...

various biological bone g rafts have been used for osteogenes i s , osteoconduction and even osteoinduction, but due to systemic influences and local factors, the outcome of successful incorporation of a bone graft has not been satisfactory. this study was therefore conducted on 15 clinically healthy adult dogs between 1 to 3 years of age weighing 20 to 30 kg to evaluate the effect of bone ceme...

background although the assignment and suturing of the spreader graft to the septum is a routine part of rhinoplasty, it is a time wasting procedure and some problems may occur. rather, autospreader flap is a new method that the dorsal part of the upper lateral cartilage is used as its own graft. in the present study, we intended to compare the functional and aesthetic outcomes of these two tec...

dermatofibrosarcoma protuberans (dfsp) is very rare tumor of dermis layer of skin with the incidence of only 1 case per million per year. dfsp rarely leads to a metastasis (less than 5% have metastasis), but dfsp can recur locally. we publish a rare case of a recurrent dermatofibrosarcoma protuberans and its management with radical excision and interval skin grafting.

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...

introduction: due to its immunosuppressive properties, local graft irradiation (lgi) has been proposed as a second line therapy for treatment of acute kidney rejection. case presentation: in this case-series we report 6 patients with biopsy proven acute kidney allograft rejection refractory to conventional antirejection therapy who underwent lgi for treatment of acute rejection at our center. t...
