The article ''Endorectal MRI accuracy and its staging evaluation contribution in prostate cancer: a North African ethnic group'' has been retracted at the request of the editor because it contains significant verbiage plagiarizing another publication: ''Endorectal MRI for prediction of tumor site, tumor size, and local extension of prostate cancer'' (Nakashima et al (2004) Urology 64 (1):101-105).

The simultaneous presence of primary carcinomas in the same patient is uncommon and synchronous primary tumors involving the kidney and pancreas are extremely rare. There are a few reports in the English literature of synchronous primary malignancies of the kidney and pancreas. We present a 62-year-old man who had weight loss of 9 kg and epigastric pain. Findings showed a Furhman grade II renal papillary carcinoma confined to the kidney and a synchronous well differentiated pancreatic ductal adenocarcinoma.

Gastric banding was carried out in 30 patients as a treatment for morbid obesity. The mean excess weight lost at 3 months was 32.6 per cent (27 patients) and 69.7 per cent at 2 years (eight patients). Fifteen patients required 22 reoperations for technical complications. Two patients underwent removal of the band and seven patients were converted to a stapled vertical Silastic ring gastroplasty. Although gastric banding appears to be a satisfactory method of achieving weight loss, the complication and reoperation rates are unacceptable in our hands. It is recommended that this operation should no longer be used as a treatment for morbid obesity.
