Factors influencing R wave amplitude in patients with ischaemic heart disease.

R wave amplitude changes during exercise have been ascribed to alteration in left ventricular volume and their measurement advocated for the improved diagnosis of coronary disease. The reproducibility of exercise QRS changes and their relation to ST segment depression, respiratory pattern, and left ventricular volume during ischaemia were studied in 10 patients with angina and coronary disease. QRS amplitude was measured in a 16 lead precordial map during three identical exercise tests in each patient and left ventricular volume assessed continuously using gated blood pool imaging with a single scintillation probe during manoeuvres to provoke ischaemia. During exercise, QRS amplitude increased or remained unchanged in four patients and fell in six patients in a consistent manner for each patient. R wave amplitude was not affected by changes in respiratory pattern. R wave amplitude did not alter in 33 of 39 episodes of left ventricular volume increase (mean 32%) or decrease (mean 36%) in end-diastolic counts. These findings suggest that precordial R wave changes during ischaemia are not determined primarily by alteration in left ventricular volume or the respiratory pattern. Though reproducible in each patient and following a definite relation to ST segment depression, the variable directional response during exercise suggest that R wave amplitude changes have little diagnostic value.

Renal elimination of amiodarone and its desethyl metabolite.

Two patients in chronic renal failure receiving amiodarone for the treatment of refractory arrhythmias were commenced on dialysis, in one case, intermittent peritoneal dialysis, in the other, haemodialysis. Plasma concentrations of amiodarone and its desethyl metabolite were consistent with the dose received, whilst neither compound was recovered in the dialysate. In these patients and in 10 additional patients with normal renal function taking amiodarone, only negligible amounts of either compound were detected in urine. These findings suggest that amiodarone may be a suitable antiarrhythmic agent for use in patients with chronic renal failure.

Aortic aneurysm in a patient with long-standing hypothyroidism.

Hypothyroidism over a lifetime is rare. Such a case is reported due to post-coupling dyshormonogenesis in a patient who had developed an aortic aneurysm. It is proposed that the aortic aneurysm could have arisen as a direct consequence of the hypothyroidism. Furthermore, Reilly bodies, which are deposits of mucopolysaccharide, were found in the peripheral blood leucocytes; these have never been previously described in hypothyroidism. It is suggested that they may reflect an underlying disturbance in mucopolysaccharide turnover which could have resulted in weakening of the aortic wall and aneurysmal formation.

Rapid and automated identification of Enterobacteriaceae with the abbott MS-2 system and API-20E versus conventional methods.

The ability of the MS-2 (Abbott Laboratories, Diagnostic Division, Dallas, Texas) to rapidly identify Enterobacteriaceae, was evaluated. The results of the MS-2 and of the Analytab API-20E test strip were compared with those obtained from conventional tubed media. The MS-2 and API-20E completely agreed with the conventional method for 92% and 95% of the organisms, respectively. Only 0.5% (MS-2) to 0% (API-20E) of the organisms tested led to complete disagreement. Approximately 6% (MS-2) and 3.5% (API-20E) of the organisms would have shown complete agreement if additional tests had been done. For 1.5% of the organisms the octal code could not be found in the API-20E profile index. It was concluded that the MS-2 system provides a rapid (5 to 6 h) and accurate method for the routine identification of Enterobacteriaceae.

Substance abuse, public health and the pediatrician.

Substance abuse is a major public health problem affecting increasing numbers of children and adolescents. It is important to consider the various etiologic factors and the detrimental effects on individuals and social welfare. Intervention refers to early diagnosis, treatment, rehabilitation, and resocialization, as well as prevention, education, and alternatives. Its effectiveness depends on: the recognition of the problem as biopsychosocial; a humanistic/holistic approach; and collaboration of family, school, work, etc., with the physician and the patient. Training in substance abuse will prepare the pediatrician to meets his responsibilities as clinician, school consultant, family counselor, public health worker, and community educator.

The use of minor tranquilizers with jail inmates.

The decision of whether or not to prescribe minor tranquilizers becomes an apparent dilemma for mental health professionals working in jails. By dispensing anxiety-reducing drugs, they may help the inmate cope with existing hardship conditions, but they may also contribute to drug dependency. A survey of California county jail systems revealed a general distrust of minor tranquilizers as a therapeutic modality. The authors conducted a medication-linked group therapy program in one county jail to provide an alternative to the usual policies governing use of tranquilizers.

Therapeutic effects of methadone and 1-alpha-acetylmethadol.

Many heroin addicts prefer methadone maintenance treatment to 1-alpha-acetylmethadol(LAAM) because of the "rush-like" effect of methadone. Although there have been no observable differences in the safety and effectiveness of the two drugs, LAAM appears to lead to a more stable, consistent physiological state. The authors report on two patients who had ego defects characterized by severe mood swings. Both patients preferred LAAM to methadone because of its stabilizing effect and smoother action.

A controlled comparison of cyclazocine and naloxone treatment of the paroled narcotic addict.

A controlled, double-blind study of the comparative effectiveness of the narcotic antagonists, cyclazocine and naloxone, was undertaken in a metropolitan narcotic clinic offering an abstinence program involving urine monitoring and ancillary counseling services. Seventy male addict parolees were randomly assigned to 6-month treatment with either cyclazocine, 4 mg administered on a daily basis, or naloxone, 500-2,000 mg administered on a locally developed and researched 'contingent' basis, i.e., whenever there was indication of narcotic drug use (daily and contingent placebos were utilized to preserve the double-blind). Criteria of treatment effectiveness included narcotic drug usage, clinic attendance, length of participation in the program, disposition at 6 months, and incidence of side effects. The two subsamples of 35 individuals were similar with respect to relevant demographic characteristics. Examination of comparative effects revealed little to no significant differences between the two groups in terms of measures of program adherence, treatment outcome, and personal and social adjustment. Side effects were more prevalent among cyclazocine patients. Typically, these included moderately severe somatic effects and perceptual and cognitive disturbances.
