    Notes: Abstract PURPOSE: This study was undertaken to identify the optimum level of stapled ileal pouch-anal anastomosis. METHOD: A prospective, randomized trial was completed to compare double-stapled ileoanal anastomosis placed at the top of anal columns (high, n=26) with anastomosis at the dentate line (low, n=21). RESULTS: There was no significant difference in the overall complication rate between operations (high, n=7,vs. low, n=8; P〈0.21). Pouchanal functional score (scale 0–12; 0=excellent, 12=poor) was significantly better in the high anastomosis group (median (range): 2 (1–9) vs. 5.5 (1–12); P〈0.05). Incontinence occurred in only two patients randomized to high anastomosis compared with six in the low anastomosis group. Nocturnal soiling was reported in three patients after high anastomosis and in six patients after dentate line anastomosis. Both operations caused a significant but comparable reduction of maximum anal resting pressure (31 percent after high anastomosis (P〈0.05); 23 percent after low anastomosis (P〈0.05)). However, a significant fall in functional length of the anal canal was only seen after a low pouch-anal anastomosis (P〈0.05). CONCLUSION: Stapled pouch-anal anastomosis at the top of anal columns gives better functional results compared with a stapled anastomosis at the dentate line.

    Notes: Abstract The results of a survey of air particulates at 23 sites across Jamaica for total suspended particulates (TSP), Al, Br, Cl, Na, Pb, and V, by instrumental neutron activation analysis (INAA) and X-ray fluorescence analysis (XRF) are reported. The geometric mean of TSP values, 35 g m-3, is well within the World Health Organisation's standard of 60 g m-3 for TSP, but in areas of high vehicular traffic density the TSP values exceeded this limit. The correlation coefficient between Br and Pb concentrations in the particulates was 0.92 and the Br/Pb ratio of 0.38 compares well with a ratio of 0.39 found in commercial petrol indicating that the exhaust from vehicular traffic is the major source of Pb in atmospheric particulate matter in Jamaica.
