The endoscopic aspects of both primary and secondary tuberculosis in children and adults received unusual attention in 1958, and the reports on endobronchial involvement in primary infections of childhood were noteworthy.
Observations on esophagitis and hiatus hernia continued to predominate in the literature on esophagology, and even though considerable basic research was carried out on the esophagogastric sphincter the exact mechanism remains unsettled.
Utilizing the blood level of dogs, Adriani and Campbell1 undertook to determine the absorption rate of topically applied tetracaine and cocaine. Blood levels were obtained after topical application of the drugs in the pyriform fossa, the trachea, and the bronchi and after rapid I.V. injection, slow I.V. injection, and infiltration into subcutaneous tissue. The quantity of drug which resulted in no detectable blood level when infiltrated subcutaneously gave levels when topically applied equal to one-third to one-half of those after rapid I.V. injection.
