Biliopancreatic ascariasis: endoscopic approach.

From June 1985 to June 1999, 120 patients were diagnosed by means of panendoscopy, choledocoscopy, and endoscopic retrograde cholangiopancreatography as having biliary and pancreatic ascariasis. All duodenoscopic procedures were performed under fluoroscopic control. Endoscopic extraction was successful in 99 of 108 (92%) patients, some of whom had had previous endoscopic sphincterotomy.

Changes in the treatment of wheezing children in the emergency department.

This study prospectively examined the pharmacologic treatment of all wheezing children presenting to a pediatric emergency department from December 1987 to September 1991 (10,091 cases). There were increasing trends in rate of hospitalization, use of oxygen saturation measurements, use of corticosteroids and beta agents at discharge, and use of aerosolized bronchodilators administered in the emergency department. This cohort shows decreasing trends in use of theophylline and the use of subcutaneous bronchodilators administered in the emergency department.

Oxygen saturation changes during the pediatric emergency department treatment of wheezing.

This study examined the oxygen saturation (OSAT) changes measured by pulse oximetry during emergency department (ED) bronchodilator treatment of wheezing patients. Data were collected prospectively on two cohorts (November 1987 to November 1988, 2,468 patients; and December 1988 to October 1990, 4,913 patients) presenting to a pediatric ED with wheezing-associated respiratory illnesses. Initial, posttreatment, and discharge OSAT was recorded in many of these patients.
