Serial histological changes in heterotopic canine cardiac allografts are reported using a percutaneous needle biopsy technique. This procedure can be performed without general anaesthesia or major complications and gives a high success rate (over 98%) with representative sampling of the organ. A pattern of acute rejection is described and compares well with the findings in other orthotopic and ...

OBJECTIVES Investigate the recurrence of chronic otitis media after primary and revision myringoplasty, compare long-term anatomic and audiologic results of underlay and overlay myringoplasty, and examine the prognostic factors. STUDY DESIGN Retrospective study. PATIENTS Approximately 1,040 adult patients with chronic simple otitis media undergoing a myringoplasty (overlay and underlay) by ...

Two independent experiments were conducted on the effect of various factors, such as cultivars, growth activity rootstock and its treatment, with Trichoderma atroviride graft success annual beech plants. The first experiment concerned propagation five cultivars rootstocks that are active (with activity), grown before treatment in multi-cell plant trays (plastic seedling trays) or bare-root dorm...

Organ transplantation is indeed a revolution in management of end-stage organ failure. The one year graft survival rates for solid organs now routinely exceed 85 per cent for the kidney, liver and heart. The enhanced success rate is due to better immunosuppression, improvement in surgical techniques, organ preservation and better understanding of the immunology of rejection. The small intestine...

CONTEXT Reconstructive surgeons who perform urethroplasty have a variety of techniques in their armamentarium that may be used according to factors such as aetiology, stricture position, and length. No one technique is recommended. OBJECTIVE Our aim was to assess the reported outcomes of the various techniques for graft augmentation urethroplasty according to site of surgery. EVIDENCE ACQUI...

COMMENT The May-June 2016 issue of the International Braz J Urol presents original contributions with a lot of interesting papers in different and as usual the editoŕs comment highlights some papers. We decided to comment 2 papers about a very usual topic in urologic practice: The Urethral Stricture. Doctor Prabha and collegues from India performed on page 564 an interesting study about the sin...

A new potassium persulfate redox system has been investigated for the graft polymerization of vinyl monomers. In this study potassium persulfate system was used for initiation the polymerization. Graft polymerization of acrylonitrile (AN) onto starch (Sta) was carried out in aqueous solution using potassium persulfate (I) redox system. It was found that the percentage of grafting and rate of gr...

OBJECTIVES To evaluate graft types used for maxillary sinus augmentation and review success rates of dental implants inserted in these areas, analyzing the graft materials used, implant surface types and the moment of implant placement. STUDY DESIGN A meta-analytic study reviewing articles on sinus augmentation published during the last ten years. RESULTS 3,975 implants placed in sinus augm...

BACKGROUND Urethral stricture disease is a challenging condition to treat and several approaches including direct visual internal urethrotomy (DVIU) and anastomotic or augmentation urethroplasties based on the use of flaps and graft have been reported. The aim of this study is to determine risk factors for stricture recurrence and complications in patients having buccal mucosal graft (BMG) uret...
