New vessel formation, a highly-regulated, active process commencing in the embryo and evident notably during the pubertal growth spurt, is essential for normal prostate development. Reactivation of this process in response to physiological stimuli, particularly hypoxia in mature tissues, occurs with new vessels forming principally from stromal components. Although angiogenesis is complex, putatively involving a multitude of angiogenic factors and inhibitors, there is powerful evidence of the importance of the VEGF system in the development of both the normal prostate and prostate cancer. Recent advances include an understanding of how castration acts through the VEGF system to inhibit angiogenesis. Stromal-endothelial and epithelial-endothelial interactions are just beginning to be investigated. A better understanding of how physiological angiogenesis is controlled should help to provide further insights into the mechanism of disregulated angiogenesis in tumours. Ultimately, new antiangiogenic agents are likely to find a role in the management of patients with prostate cancer.

Post-transplant lymphoproliferative disease (PTLD) in Epstein-Barr virus (EBV) seronegative solid organ transplant recipients remains a significant problem, particularly in the first year post-transplant. Immune monitoring of a cohort of high-risk patients indicated that four EBV seronegative transplant recipients developed early-onset PTLD prior to evidence of an EBV humoral response. EBV status has been classically defined serologically, however these patients demonstrated multiple parameters of EBV infection, including the generation of EBV-specific CTL, outgrowth of spontaneous lymphoblastoid cell lines, and elevated EBV DNA levels, despite the absence of a classic EBV antibody response. As EBV serology is influenced by both immunosuppression and cytomegalovirus immunoglobulin treatment, both the EBV-specific CTL response and elevated EBV levels are more reliable indicators of EBV infection post-transplant.

The modern understanding of the pathogenesis of migraine, based on the concept that it is a neurovascular disorder, is often thought to have emerged from the work of Harold Wolff in the period 1932-1962. However, over the preceding 300 years, from William Harvey onwards, various hypotheses of the pathogenesis of migraine had been proposed, a few bearing reasonably strong resemblances to Wolff's ideas, though based on less adequate evidence. Many of these earlier hypotheses regarded migraine either primarily as a vascular (e.g., Willis, Wepfer, Latham) or as a neural disorder (e.g., Harvey, Lieving and his 'nerve storms'). There were also variations around these two major themes and in the 19th Century a number of neurovascufar type hypotheses emerged assigning a major role in migraine pathogenesis to the autonomic nervous system. In addition, during the three centuries there were a number of other hypotheses based on different postulated pathogenic mechanisms, some quite ingenious, which had relatively brief vogues. No hypothesis has yet proved capable of explaining all the features of migraine satisfactorily. (c) 2005 Elsevier Ltd. All rights reserved.
