Primary lymphoma of the liver is extremely rare, and is more common among immunocompromised patients. It typically occurs during the fifth decade of life and has a male predominance. Abdominal pain, weight loss, and fever are the normal symptoms. Liver function tests are usually upset. Ultrasonography, computed tomography, and magnetic resonance imaging can(More)
Brain-dead donors are the major source of lungs for transplantation. Brain death is characterized by two hemodynamic phases. Initially, massive sympathetic discharge results in a hypertensive crisis. This is followed by neurogenic hypotension. Up-regulation of pro-inflammatory mediators occurs in all organs and lung injury develops; this can adversely(More)
The paucity of suitable lung donors and the high early mortality as the result of primary graft failure remain major challenges in pulmonary transplantation. There is evidence that the lung is injured in the donor by the process of brain death and often is made unusable or fails posttransplantation after amplification of the injury by the process of(More)
AIMS To review our institution's practice of treatment of a mammographically detected population of ductal carcinoma in situ (DCIS) patients and to determine the outcome. METHODS Between April 1989 and March 1994, 304 women with median age 59 years (range 51-65) with DCIS detected on screening mammogram, were treated in the Newcastle General and Royal(More)
Sympathetic discharge and hypertensive crisis often accompany brain death, causing neurogenic pulmonary edema. Progressive systemic inflammatory response develops, which can injure the lung further. We investigated whether (a) early hemodynamic injury during donor brain death increases reperfusion injury after lung transplantation and (b) delaying lung(More)
BACKGROUND The autonomic storm accompanying brain death leads to neurogenic pulmonary edema and triggers development of systemic and pulmonary inflammatory responses. Neurogenic vasoplegia exacerbates the pulmonary injury caused by brain death and primes the lung for ischemia reperfusion injury and primary graft dysfunction in the recipient. Donor(More)
BACKGROUND Renal transplant recipients with a positive historic cross-match due to donor T cell-directed IgG antibodies are considered to have decreased graft survival, even if their current serum is negative prior to transplantation. With the use of flow cytometric cross-match for testing current sera, false-negative results could be eliminated and the(More)
BACKGROUND AND OBJECTIVES Patients with adrenal metastases from bronchogenic carcinoma are considered incurable and any surgical treatment is usually excluded. A review of the few cases of adrenalectomy for metastases from lung cancer that have been reported in the literature shows that good results can be achieved in selected patients. We propose a(More)
OBJECTIVE At the time of lung transplant, we routinely perform bronchoalveolar lavage (BAL) of the donor lungs on the recipient operating table immediately before implantation, for bacterial and fungal cultures. We sought to determine whether the results correlate with the outcome. METHODS We retrospectively analysed 115 consecutive cadaveric lung(More)
INTRODUCTION Donor brain death is the first injurious event that can produce inflammatory dysfunction after pulmonary transplantation. This study was designed to determine whether stimulation of the toll-like receptor (TLR) system contributes to the changes produced by brain death. MATERIALS AND METHODS Rats were repeatedly treated with specific agonists(More)
