The present study was designed to carry out an in vivo and in vitro comparative evaluation of three bio-scaffold augmentation devices used for superficial digital flexor tenorrhaphy in donkeys. Twenty-four clinically healthy donkeys were assigned for three treatment trials (n = 8) using one of three bioscaffold materials (glycerolized bovine pericardium xenograft, tendon allograft and allograft...

We admitted a maintenance haemodialysis patient with hypotension and weakness. He had undergone cadaveric renal transplantation 19 years earlier. He had lost his kidney due to chronic allograft nephropathy 1 year after transplantation and returned to haemodialysis. He had hypotension, especially remarkable during haemodialysis. He also had hepatitis C but no cirrhosis. The patient denied a prev...

Human amniotic membrane proved to be a versatile and useful temporary biologic dressing in studies involving 120 patients. Wounds, both traumatic and nontraumatic in origin, responded to a protocol that allowed coverage of tissues as diverse as exposed bowel, pleura, pericardium, blood vessels, tendon, nerve and bone. Wounds unresponsive to usual therapeutic measures responded to membrane appli...

BACKGROUND The purpose of this study was to prospectively determine the immunogenicity of nonvalved allograft tissue used to repair congenital heart defects. METHODS AND RESULTS We prospectively analyzed the immune response of 11 children, 1.4 months to 10 years of age, who required nonvalved allografts to alleviate stenosis during repair of congenital heart defects. In 7 patients, pulmonary ...

PURPOSE The aim of the present study was to evaluate the effectiveness of using a mineralized bone cortical allograft (MBCA), with or without a resorbable collagenous membrane derived from bovine pericardium, on alveolar bone remodeling after immediate implant placement in a dog model. METHODS Six mongrel dogs were included. The test and control sites were randomly selected. Four biradicular ...

OBJECTIVE Posterior fossa decompression with duraplasty (PFDD) is often used for Chiari malformation type I (CM-I), but outcomes associated different dural graft materials are not well characterized. In this meta-analysis, the authors examined complication rates and after PFDD CM-I autografts four types of nonautologous grafts. METHODS A literature search numerous electronic databases (Ovid Med...

Congenital defects of the pericardium are considered rare. Until 1979 , the reported cases were only about 200.1 Total absence of the left pericardium is the most common defect2 and less common is a partial defect of the left pericardium. Other types, i.e. isolated right-sided defects, total pericardial absence and diaphragmatic pericardial defects are very rare.3 Before the last decade, t...

Tracheotomy is used to keep and control airways open and protect them in head and neck operations.1-3 Tracheotomy is opening a direct airway through an incision in the trachea observed as a stoma in the lower throat and it is usually performed in serious head and neck traumas, tumors, bleedings and cases that intubation with endotracheal tube is not possible. This method has several advantages ...
