Age and alcoholism: independent memory decrements.

Similarities and differences in performances on 18 verbal and nonverbal memory tasks were studied in young and old alcoholics and in young and old controls as test of hypotheses postulating that cognitive decrements from alcoholism either mimic "premature aging," are "age sensitive," or are "independent" from those of normal aging. Young and old alcoholics were matched in length and rate of heavy drinking and were also equated with their controls in age, education, and vocabulary. The multivariate memory and decision data, when converted to independent factor scores, separated alcoholic from control groups on a factor reflecting memory for auditorily presented information. This was independent from factor scores affected mainly by age, such as memory for visuospatial items or decision bias. Age and alcoholism produced overlapping but distinctly different profiles of memory impairments. Decrements in young alcoholics did not resemble those of aging nor did old alcoholics surpass old controls in any but one factor, so that neither the premature aging nor the age sensitivity hypothesis were invariably supported.

[Arrhythmias in healthy sailors].

Results are presented of 24-hour monitoring by Holter's method of ECG in 50 healthy seamen aged 29-55 years (mean 47.7 years), in whom clinical examination, chest radiography, resting ECG records, and echocardiography confirmed normal condition of the cardiovascular system. In 36% of the seamen premature beats of various origin were elicited. Supraventricular extrasystolic beats were demonstrated in 8%, atrioventricular-junction beats in 8%, and ventricular ectopic beats in 18%. In one case simultaneous occurrence of junction beats and ventricular beats was found. In 28% of the subjects sinus bradycardia was noted, and in 1 seaman two episodes of sinus tachycardia were recorded. The intensity of the observed arrhythmias was low.

Familial dilated (congestive) cardiomyopathy.

Dilated (congestive) cardiomyopathy (DCM) in two brothers is reported. The clinical course in both cases was dominated by severe congestive heart failure (CHF) with heart rhythm disturbances in one sibling. The onset of the disease was preceded by influenza-like episodes in one case. HLA typing carried out in this patient demonstrated the presence of the A11 antigen which is shown to be more frequently encountered in this cardiomyopathy.
