Cardiac conduction defects in patients older than 60 years with aortic stenosis with and without mitral anular calcium.

The prevalence of conduction defects was investigated in 51 patients older than 60 years with aortic stenosis (AS) who underwent aortic valve replacement. Thirty one of the 51 patients, (61%) had associated mitral anular calcium (MAC). The mean age and prevalence of coronary artery disease, systemic hypertension and diabetes mellitus were similar in both groups. The prevalence of conduction defects (atrioventricular block, sinoatrial disease, bundle branch block, left anterior hemiblock or intraventricular conduction defect) was 18 of 31 (58%) in patients with MAC and 5 of 20 (25%) in patients without MAC (p less than 0.025). We conclude that patients older than 60 years with AS have a high prevalence of MAC, and that the prevalence of conduction defects is higher in patients older than 60 years with combined AS and MAC than in patients with AS without MAC.

Self-tattooing by schoolchildren.

Of 779 third-year pupils from seven secondary schools examined for evidence of self-tattooing, 31 (4%) had tattooed themselves. More boys (27/513, or 5.2%) than girls (4/266, or 1.6%) had tattooed themselves. One hundred and fifty six separate marks were identified in the tattooed boys and sixteen in the girls. The most popular sites were the fingers and back of the left hand, and the front and back of the left forearm. Only 2 pupils remained pleased with their tattoos and 19 expressed strong remorse. Waiting lists for the removal of such tattoos are very long. The craze for self-tattooing by schoolchildren should be curbed.
