STUDY OBJECTIVES To determine the causes of death in patients dying within 30 days after lung transplantation at the University of Florida, to assess the importance of several diagnostic modalities for determining the causes of their decline, and to construct an algorithm for the evaluation of patients with severe respiratory compromise occurring early after lung transplantation. DESIGN Retro...
BACKGROUND Skin allograft is the gold standard of wound coverage in patients with extensive burns; however, it is considered as a temporary wound coverage and rejection of the skin allograft is considered inevitable. In our study, skin allograft as a permanent coverage in deep burns is evaluated. METHODS Skin allograft survival was assessed in 38 patients from March 2009 to March 2014, retros...
BACKGROUND The aim of this study was to evaluate the diagnostic utility of PAI at detecting thyroid microcalcifications at 700 nm laser wavelengths. METHODS This study included 36 resected samples in 18 patients. To evaluate the PA manifestation of microcalcifications in PAI, gray level histogram and co-occurrence matrix (COM) texture parameters were extracted from the 3 fixed ROI US and PA i...
A late dysfunction of a renal allograft refers to a progressive decline in renal function manifested)3 months after transplantation. A late dysfunction may have several causes, such as chronic rejection, chronic allograft nephropathy, chronic calcineurin inhibitor toxicity, de novo or recurrent renal disease and acute rejection. An allograft biopsy is necessary to establish a definitive diagnos...
BACKGROUND Standardization of renal allograft biopsy interpretation is necessary to guide therapy and to establish an objective end point for clinical trials. This manuscript describes a classification, Banff 97, developed by investigators using the Banff Schema and the Collaborative Clinical Trials in Transplantation (CCTT) modification for diagnosis of renal allograft pathology. METHODS Ban...
BACKGROUND Poor quality dried blood spot (DBS) specimens are usually rejected by virology laboratories, affecting early infant diagnosis of HIV. The practice of combining two incompletely-filled DBS in one specimen preparation tube during pre-analytical specimen processing (i.e., the two-spot method) has been implemented to reduce the number of specimens being rejected for insufficient volume. ...
BACKGROUND Cardiac allograft rejection and vasculopathy are the main factors limiting long-term survival after heart transplantation.In this pilot study we investigated whether non-invasive methods are beneficial to detect cardiac allograft rejection (Grade 03 R) and cardiac allograft vasculopathy. Thus we compared multi-slice computed tomography and magnetic resonance imaging with invasive met...
CARDIAC histology has been reviewed in 16 patients between April 1980 and March 1981 to evaluate the effect of cyclosporin-A (CyA) and low-dose prednisone in a new trial of orthotopic cardiac transplantation. The usual maintenance dose of CyA has been 5-10 mg/kg/day, and prednisone 15-20 mg/ day.1 HydrOC()rtisone, 1 g intravenously, has been used to combat rejection. usually without alteration ...
background evaluation of a transplanted liver by imaging techniques and enzyme changes is sensitive to hepatocellular or biliary problems, but in most instances liver allograft biopsies are performed in order to find out the final reason for these changes. objectives it’s been about 17 years (with more than 1326 cases) since the first liver transplantation in the namazi hospital of shiraz unive...
