An efficient Th1-driven adaptive immune response requires activation of the T cell receptor and secretion of the T cell stimulatory cytokine IL-12 by activated antigen-presenting cells. IL-12 triggers Th1 polarization of naive CD4(+) T cells and secretion of IFN-gamma. We describe a new heterodimeric cytokine termed IL-27 that consists of EBI3, an(More)
We have biologically characterized two new members of the IL-17 cytokine family: IL-17F and IL-25. In contrast to conventional in vitro screening approaches, we have characterized the activity of these new molecules by direct in vivo analysis and have compared their function to that of other IL-17 family members. Intranasal administration of adenovirus(More)
Anal and recto-sigmoid Crohn's disease may rarely be complicated by the development of local malignancy. Eight patients with this association were identified from the records of St. Mark's Hospital between 1947 and 1988 and two from The London Hospital. The aetiology of the malignancies and their surgical management have been examined. Eight patients had(More)
BACKGROUND With improvements in ultrasonography more polypoid lesions of the gallbladder (PLGs) are being detected. The management of these is controversial. METHODS The demographic, radiological and pathological data of 38 patients with ultrasonographically detected PLGs were reviewed. A Medline search for such lesions was performed and a review of the(More)
Anastomotic leakage is a major problem in colorectal surgery, and previous studies have suggested that intraoperative identification of leaks allows repair at the time of surgery. This study examined whether testing allowed a defunctioning ileostomy to be safely omitted. A series of 102 consecutive patients underwent left-sided colorectal resection, 52(More)
AIMS Secondary rectal carcinoma occurs by invasion of the rectum by local primaries or by metastatic spread from a distant primary. The principle management of primary rectal carcinoma is surgery, but this is not usually the case for secondary carcinoma. This study investigates how these two may be differentiated and inappropriate surgery, in particular(More)
INTRODUCTION Introducing laparoscopic colorectal surgery is a challenge to the whole surgical team. It is usual for an assistant to hold the laparoscope and be responsible for the surgeon's view of the operative field and a lack of expertise in the assistant can add significant difficulties. The EndoAssist is a robotic device that replaces the human(More)
The pattern of recurrent tumour following 'curative' colorectal surgery was examined in a necropsy series and a prospective clinical series. In the necropsy series the commonest pattern of recurrence was disseminated disease (73 per cent) and recurrence in a single site was much less common (27 per cent). In the clinical series recurrence in a single site(More)
Razoxane is one of the few agents which has shown activity in the treatment of advanced colorectal cancer. The drug has therefore been evaluated in a prospective randomized controlled trial as an adjuvant to surgery for resectable colorectal cancer. The results to median follow-up of 5 years are reported here. Accrual has ceased and a total of 272 patients(More)
