Acute lymphoblastic leukemia: end-result analysis of treatment and prognostic factors in Indian patients.

Acute Lymphatic Leukemia (ALL) patients seen during the period 1974-1978 at the Tata Memorial Hospital. Bombay, are analyzed retrospectively to evaluate the clinical features at presentation, results of sequential therapy, and prognostic factors. A total of 301 patients were registered during the study period.

Diagnostic and prognostic significance of exercise-induced premature ventricular complexes in men and women: a four year follow-up.

Two hundred eighty patients (197 men and 83 women) with normal rest electrocardiograms and no history of prior myocardial infarction were referred for evaluation of chest pain. It was found that exercise-induced premature ventricular complexes had a lower sensitivity, specificity, positive predictive value and negative predictive value in predicting significant coronary artery disease than exercise-induced ST segment depression greater than or equal to 1 mm. The incidence of exercise-induced premature ventricular complexes was not significantly different in patients with no significant coronary artery disease, single vessel disease or multivessel disease.

Total body irradiation in chronic myeloid leukemia.

Total body irradiation (TBI), given as 10 rad daily for five days a week for a total dose of 150 rad has been used in an attempt to control the chronic phase of chronic myeloid leukemia (CML). Thirteen patients with CML received fractionated TBI leading to rapid and good control of WBC count without any adverse reaction. The chronic phase of CML could also be controlled with TBI, even in three patients who were resistant to busulfan.

Clinical and echocardiographic characteristics of patients with mitral anular calcification. Comparison with age- and sex-matched control subjects.

The clinical and echocardiographic features of 104 patients (53 women and 51 men) with mitral anular calcification (MAC) were compared with those of 121 age- and sex-matched control subjects (62 women and 59 men) without MAC. The incidence of coronary artery disease, rheumatic heart disease, systemic hypertension, and diabetes mellitus was similar in both groups. Patients with MAC had a greater incidence of cardiomegaly (p less than 0.

Therapy-related leukemia. A report of five patients and a review of the literature.

5 patients developed acute nonlymphocytic leukemia (ANLL) 2-4 years following the use of various cytotoxic agents for other primary disease. Alkylating agents were responsible for development of ANLL in 3 patients while mitomycin-C and methotrexate appear to be linked with leukemia transformation in the remaining 2 patients. 3 patients had a prolonged preleukemic phase preceding ANLL.

Determination of erythrocyte superoxide dismutase, catalase, glucose-6-phosphate dehydrogenase, reduced glutathione and malonyldialdehyde in uremia.

Erythrocyte superoxide dismutase (SOD: EC 1.15.1.

High prevalence of symptomatic bradyarrhythmias due to atrioventricular node-fascicular and sinus node-atrial disease in patients with mitral anular calcification.

Mitral anular calcification (MAC) is associated with high frequency of conduction defects. To delineate this association in patients with symptomatic bradyarrhythmias, 68 consecutive patients requiring pacemakers (group I) and 56 matched controls (group II) were studied. The patients comprised 41 men and 27 women, whose ages ranged from 24 to 92 years (mean 68).

Ventricular fibrillation complicating pacemaker insertion in acute myocardial infarction.

Temporary transvenous pacing catheters were placed in 101 patients with acute myocardial infarction (MI) for the management of bradyarrhythmias or conduction disturbances. Fourteen (14%) patients (group A) developed ventricular fibrillation (VF) at the time of pacing catheter manipulation in the right ventricle. Compared to the remaining 87 (86%) patients (group B), the patients in group A were younger (56.

Digoxin-induced positive exercise tests: their clinical and prognostic significance.

To evaluate the influence of digoxin on the results of exercise testing and the prognostic significance of digoxin-induced positive exercise tests, 98 healthy men, aged 22 to 70 years, were studied. All had normal initial exercise test results. All took digoxin, 0.
