...always reliable: the "flooding" technique often fails to fill the arteries with enough dye, and still pictures do not clearly separate small vessels that are superimposed on each other. One of the major breakthroughs at last week's AHA meeting came when the Cleveland Clinic's Drs. Earl Shirey and F. Mason Sones Jr. demonstrated a diagnostic technique that seems likely to improve on the arteriogram-a method of coordinating the ray, a specially designed catheter and a movie camera to produce the first high-peed (60 frames per second) pictures of he coronary arteries in action...
Monitoring the operation through an image intensifier-a refined fluoroscope that produces an X-ray image 1,500 times Drighter than the old-style fluoroscopic screen-Drs. Sones and Shirey then release a tiny amount of radiopaque dye through the catheter into the aorta in order to locate the spot at which right and left coronary arteries join the circulation's main stem. "The rest," says Sones, 'requires only a little bit of simple dexterity." The catheter is successively slipped into both coronary arteries, and small injections of dye (2 cc. to 5 cc.) are sufficient to silhouette...
What Hit Him? But whiplash should not be so lightly dismissed, insist Drs. Robert Leopold and Harold Dillon of the University of Pennsylvania's Department of Neurology and Psychiatry. In a study of 47 whiplash victims, Drs. Leopold and Dillon found a considerably higher incidence of actual physical injury (14 "severe" cases, 26 "moderate") than did Dr. Threadgill...
Threatened Control. The human personality is peculiarly vulnerable to the shock of a sudden assault from behind, argue Drs. Leopold and Dillon. This, they theorize, may trigger a "denial mechanism" that prevents the victim from coming to terms emotionally with the meaning and discomfort of his injury. They add: "The fact that the head and neck are the sites of injury adds to this distortion . . . almost as if the ego unconsciously perceives that the control (head) can be severed from the body. It is our thesis that the whiplash injury is psychologically unique in that both its suddenness...
...baby was born at Montreal's Royal Victoria Hospital. In the New England Journal of Medicine, Drs. Mathew H. Gault and Robert Usher report that, despite a difficult breech delivery, he seemed normal and healthy and began breathing spontaneously. But by the time he was taken to the nursery, he was pale and limp. The electrocardiogram was taken by happenstance: the hospital was making a study of heart action in prematures, and this baby seemed to have been about a month premature. The startling ECG finding alerted the doctors to the possibility of serious illness. When the baby turned...
