Abstract: Coronary angioscopy provides images of intravascular detail with greater than 0.2 mm spatial resolution and excellent contrast resolution. Using endoscopes of 1.25 to 1.8 mm outer diameter, we performed intraoperative angioscopy of the coronary arteries or saphenous vein grafts, or both, in 58 patients. Eighty-one native coronary arteries and 43 vein grafts were examined. A clear viewing field was created by infusion of crystalloid cardioplegic solution through the aortic root during cardiopulmonary bypass. Technical details crucial for obtaining high-quality images were as follows: sufficient coronary perfusion by cardioplegic solution to displace all blood; adequate intraluminal illumination; and high-quality fiberoptic and lens systems. Incomplete studies in approximately 14% of patients were related to failure to achieve these technical details and lack of scope steerability. In 30% of patients, previously unrecognized anatomic details were revealed by angioscopy. These included intimal flaps at the site of vein-to-artery anastomoses, atheromatous plaques with adherent thrombi, and hemorrhagic ulcerated plaques, not recognized on angiography. Although a coronary intimal flap developed proximal to the anastomosis during retrograde examination in two patients, no serious complications occurred as a result of the procedure. We conclude that intraoperative angioscopy is safe, provides novel information that may be clinically relevant, and has future potential for development of the techniques for coronary endarterectomy and intraoperative balloon and laser angioplasty.

Abstract: Sixty-five children viewed by their teachers as hyperactive were evaluated as to whether they would benefit from stimulant medication. All underwent extensive neurodevelopmental and educational testing. Additional information was obtained from school and parent questionnaires and interviews. Children were not placed on medication unless they demonstrated characteristic impulsive, inattentive, and/or overactive behavior in two of three environments (home, school, clinic). Fifty-two children (80%) were not placed on medication. Follow-up was completed in 80 percent, and 93 percent of these children were doing well with nonpharmacologic interventions. Initial comparison of children not placed and placed on medication revealed that age, race, SES, amount of resource help and retention could not distinguish groups. Children placed on medication had difficulties earlier in school (chi 2 = 4.88, p less than 0.05), weren't as delayed academically (chi 2 = 6.30, p less than 0.05) and had less neurodevelopmental disorders (chi 2 = 9.01, p less than 0.01). If a careful psychosocial history does not reveal impulsive, inattentive, and/or hyperactive behavior outside of school, a child should be evaluated to rule out neurodevelopmental and educational problems.

Abstract: A case of an unusual caustic ingestion involving Compound W, an over the counter wart remover is presented. Chemical burns of the tongue, pharynx and larynx developed. The active ingredient in this preparation: salicylic acid in a flexible collodion vehicle produces caustic injury through a keratolytic action, which may be enhanced by the presence of collodion.
