Quality assessment and assurance in diagnostic imaging. Theoretical and practical considerations and a quality audit of the excretory urogram

Concepts necessary to an understanding of the basics of quality assurance audits are presented. Included are specific examples that bridged theory and practice by applying the protocol to a real-life diagnostic imaging situation. This method meets the present requirements of the Joint Commission of the Accrediation of Hospitals.     

Testing for bacteriuria by home culturing in preschool girls.

Home urine culture in dipslide was performed in 297 preschool girls. Results correlated well with those of cultures at the medical office, specially if midstream urine was used. This method proved to be an inexpensive, reliable (100% sensitivity) technique for detecting significant bacteriuria in preschool girls. False-positive tests occurred in 22 cases.     

Alfred E. Moss: 1924 Indy 500 race driver, British dentist and father of Sir Stirling Moss

Alfred Ethelbert Moss (1896-1972), a highly successful London dentist, was also a pioneer in English auto racing. In 1923, 27-year old Alfred (already a dentist), arrived in Indianapolis, Indiana, ostensibly to study "advanced dental practice" at the Indiana Dental College. However, his primary motive for coming to Indianapolis was to participate in the Indy 500 race. On Friday, May 30, 1924, 22 car racers started the 12th running of the Indy 500. Among them was Alfred, who finished respectably, in 16th place. Thus, he became the first dentist to compete in the famed Indianapolis 500 race. In 1925, after months of dirt-track running around the U.S., he returned to England. His initial plan was to continue racing in his own country. However, this goal vanished as his dental career began to flourish. Soon he had developed a large and prosperous dental practice in London. In 1927, Moss married Aileen Craufurd, who eventually became a champion female race car driver in England. In 1929, the couple had a son, Stirling. By the 1950s, Stirling Moss was hailed as Britain's best known sports star, and one of the world's fastest and most versatile race drivers of all time. This article follows the life and times of the Moss family, with an emphasis on Alfred's two life endeavors racing and dentistry, and on Stirling's famed racing career. In 1999, Stirling Moss was knighted by Queen Elizabeth II.     

Colon perforation following percutaneous nephrostomy and renal calculus removal

Two patients had colonic perforation as a result of percutaneous nephrostomy placement followed by track dilatation and renal calculus removal. We present the technical aspects of nephrostomy placement and stone removal, as well as the clinical diagnosis and management of these cases. Both patients recovered well with conservative therapy and required no surgical intervention. This report reviews the anatomic considerations for percutaneous nephrostomy in patients undergoing renal stone removal.
