Recurrence of bile duct stones after endoscopic stone removal has been reported ranging from 4 to 24%. The risk of late compliions such as stone recurrence is an important issue, especially for relatively young, otherwise healthy, patients with many years of future exposure time. The risk factors true recurrence of bile duct stones after endoscopic sphincterotomy (EST) and stone clearance ...
Inhalable dust is produced when the stone is cut and by the breaking of the stones on the quarry floor during the transit of the vehicles. The bench and block cutting is wet, with minimal exposure to fine dust when assisting the cutting. Nevertheless, when the mud dries on the quarry floor, workers are exposed to the inhalation of dust raised by the wind and the transit of the vehicles. The ...
For cancers for which diabetes is a wellestablished risk factor (, liver, pancreas, gallbladder, and colorectum), odds ratios with 95% confidence intervals were also calculated while adjusting for the presence of diabetes. The odds ratio variance estimates were adjusted for the fact that a control could be sampled more than once in multiple calendar years or could later become a case. We ...
