Etoposide in combination with cytarabine, doxorubicin, and 6-thioguanine for treatment of acute nonlymphoblastic leukemia in a protocol adjusted for age.

Etoposide combined with cytarabine, doxorubicin, and 6-thioguanine was used to treat 34 patients with acute nonlymphoblastic leukemia (ANLL) in an age-adjusted protocol, with patients greater than 50 years old receiving fewer days of therapy. Complete remissions (CR) occurred in 85% of all patients (29 of 34 patients). Patients less than or equal to 50 years of age achieved a 94% CR rate (17 of 18 patients) compared to a 75% CR rate (12 of 16 patients) in older patients. Duration of remission was less for those greater than 50 years of age. The remission rate for primary ANLL was 86% (19 of 22 patients) and for secondary or relapsed ANLL was 83% (ten of 12 patients). Thus, this is effective therapy for primary and secondary or relapsed ANLL. When the days of therapy are reduced for older patients' age, the remissions are fewer and less durable.

Combined cardiac catheterization and carotid cineangiography: an analysis of complications.

Two hundred fifty-three patients underwent cardiac catheterization with selective cineangiography of the carotid arteries. Diagnostic angiograms of both the right and left carotid arteries were obtained in 240 patients (95%). Of these, 217 patients (90%) were studied without complication, 18 (8%) had minor complications, and five (2%) had major complications. Four of the five major complications occurred in patients with bilateral carotid atherosclerosis obliterans. Variations of catheterization technique used in an effort to reduce risk are discussed.

Intimal proliferation of smooth muscle cells as an explanation for recurrent coronary artery stenosis after percutaneous transluminal coronary angioplasty.

The pathologic changes in the coronary arteries of three patients who died 5, 17 and 62 days, respectively, after percutaneous transluminal coronary angioplasty were studied. Changes in the vessel wall seen early after angioplasty included focal denudation of the endothelium, splits in the intima extending to and along the inner aspect of the media, focal intimal necrosis and adventitial hemorrhage. Extensive medial dissections were seen in the coronary arteries of the two patients who died 5 and 17 days after coronary angioplasty. Fibrin was deposited on the surface of the intima, within intimal cracks and in areas of intimal and medial necrosis. Focal proliferation of smooth muscle cells was prominent on neointimal surfaces of the coronary artery from the patient who died 17 days after angioplasty. The previously dilated coronary segment from the patient who died 62 days after angioplasty was stenosed by an extensive recent proliferation of smooth muscle cells that were distributed over the entire circumference of the intimal surface as well as within gaps in the old atherosclerotic plaques. This type of intimal proliferation would appear to be responsible for the recurrent coronary artery stenosis that develops in some patients after coronary angioplasty.
