ABSTRACT
Since esophagitis is increasing in frequency, the authors reviewed case histories of patients with this disorder. The importance of radiographic examination of the stomach and duodenum in patients with esophagitis (heartburn) is stressed.

Tomograms and oblique radiographs were compared in 172 adult patients undergoing routine urography to assess the degree of renal outline visualized and to determine the best midpoint for nephrotomography. Tomograms proved better for demonstrating the renal outline (66.3% of patients demonstrating 78.4% of the renal circumference) than oblique views (only 23.2% of patients demonstrating 65.5% of the renal circumference). The combination of tomograms and oblique radiographs proved best, demonstrating 96.5% of the renal outline. Colon cleanliness was a significant factor. The midpoint of tomographic sections is determined by multiplying the anteroposterior diameter of the patient by 0.4.

Choanal atresia in a neonate is a cause of severe respiratory distress and constitutes a respiratory emergency. The authors present a case of choanal atresia and emphasize the ease of making the diagnosis both radiologically and clinically.

Locetamic acid (Cholebrine) and ipodate sodium (Oragrafin) were compared in a double blind study of 503 patients. The radiographs were evaluated for contrast density, visualization of common duct, gallstones, residual in the intestinal tract, and side effects. Cholebrine demonstrated better opacification, fewer repeat examinations, slightly greater common duct opacification, and more frequent visualization of gallstones. Oragrafin had less residue. Side effects were minimal with both contrast agents.

Indications for requesting and performing bedside radiographic examinations in an institutional setting are proposed. A prospective study of such examinations was made in a 500-bed hospital. All nursing units were evaluated for criteria used in requesting bedside examinations. It was found that general medical and surgical wards generate the greatest percentage of bedside studies, and yet their criteria for requesting such studies yielded the lowest percentage of validity. General criteria for utilization of mobile radiographic equipment could lead to better radiographs and improved allocation of equipment and personnel.
