Renal tumors diagnosed in the first 7 months of life generally have an excellent prognosis though histology is an important prognostic factor. In the first 2 months of life the prevalence of CMN is high. The relative occurrence of WT increases rapidly with age thereafter. Bilateral tumors are usually WT. Tumors with metastases at diagnosis are usually MRTK.

histopathological factors alone provide only crude prognostication; the analysis of molecular markers represents a method for refinement but research in this area has not been useful in informing therapeutic decisions or prognostication. The BCPP is a prospective longitudinal cohort study of all patients with newly diagnosed bladder cancer within the West Midlands (UK), investigating the influence of lifestyle factors on recurrence and progression, health-related quality of life, the predictive effect of a panel of molecular markers on recurrence or progression, and the establishment of Europe's largest comprehensive bladder cancer biorepository. It also incorporates the first randomized clinical trial on the efficacy of selenium and vitamin E on bladder cancer. The numbers and proportions of eligible patients recruited, questionnaires completed and specimens obtained were all recorded. RESULTSSince December 2005, 771 patients have been recruited (68% of eligible patients) and of these, 331 are currently being followed up by questionnaires. We have obtained blood, urine and tumour tissues from 92%, 80% and 80% of patients, respectively. CONCLUSIONSThe design of the BCPP has allowed this study to be incorporated into routine clinical work throughout the West Midlands, achieving high levels of recruitment, and data and specimen collection. This might represent a model for the future investigation of urological and other malignancies.

Aims: We conducted this study to examine the role of trigger point injections in females with chronic pelvic pain (CPP) of at least 6 months duration and speci¢c levator ani trigger points. Methods: This prospective study included 18 consecutive female patients with CPP and speci¢c palpable levator ani trigger points. Pain was evaluated before and after trigger point injection on a Visual Analog Scale (VAS). Patient global satisfaction (PGS) and cure rates (PGC) were also measured by aVAS on a scale of 0^100%. The trigger points were identi¢ed manually by intravaginal palpation of the levator ani bilaterally. A mixture of 10 cc of 0.25% bupivacaine, 10 cc of 2% lidocaine and 1 cc (40 mg) of triamcinolone was used for injection of 5 cc per trigger point. A 5.5 00 Iowa trumpet pudendal needle guide was used for injection. All but one injection were performed in the o⁄ce setting without sedation. Pelvic £oor muscle exercises were taught for use after injection. Success was de¢ned as a decrease in pain as measured by a VAS of 50% or more, as well as PGS and PGC scores of 60% or greater. There was a mean follow up of 3 months after trigger point injection.Results: Thirteen of 18 women improved with the ¢rst trigger point injection resulting in a comprehensive success rate of 72%. Six (33%) of 18 women were completely pain free. Conclusion: In the management of CPP, a non-surgical o⁄ce-based therapy such as trigger point injections can be e¡ective in selected patients.

Gracilis muscle transposition is an excellent procedure for treating complex rectourethral fistula. Several other local factors may affect the postoperative urinary and fecal outcome. The collaboration of colorectal and urological surgeons is necessary to achieve optimal results.

Swabs of crop contents of 635 broiler chickens were obtained from 9 Ontario and 12 Quebec processing plants and cultured for Salmonella to determine prevalence in broiler crops. Serotypes of positive cultures were determined to evaluate the serotype profile. The overall prevalence of contamination was low (4.3%). Prevalence was higher in broilers sampled in Quebec (5.8%) than in those sampled in Ontario (2.2%). In Quebec, there were differences in prevalence among the groups of broilers sampled at the various plants. These differences were believed to be attributable to differences in Salmonella prevalence among groups of flocks delivered to the plants due to the limited exposure of the chickens to the plant. The serotype profile of Salmonella isolated from the crops of broilers in this study was similar in several respects to profiles obtained from other surveys of Canadian broiler flocks using either environmental samples or cloacal swabs. Similarities included: predominance of Salmonella hadar and Salmonella heidelberg; several other common serotypes at a low prevalence; little Salmonella enteritidis isolated in other studies, and no S. enteritidis isolated in this study. Results of this field survey of Salmonella in crops of broilers are similar to those of Canadian studies of other internal and environmental sites of broilers. The similarity indicates that monitoring of Salmonella environments of flocks of live broiler chickens should define profiles of Salmonella contamination of the carcasses and would also aid in determination of Salmonella contamination status of broiler flocks. Such information would assist efforts to reduce Salmonella contamination in broiler chickens.
