A pre-Hispanic head.

This report on a male head revealed biologic rhythms, as gleaned from hydrogen isotope ratios in hair, consistent with a South-American origin and Atomic Mass Spectrometry radiocarbon dating (AMS) compatible with the last pre-Hispanic period (1418-1491 AD, 95.4% probability). Biopsies showed exceptionally well-preserved tissues.

[Medical-legal evaluation of Brugada syndrome].

Brugada syndrome is a congenital arrhythmogenic disease, characterized by alterations in sodium channels in the absence of structural myocardial changes. It leads to ventricular electrical instability, causing arrhythmias with high risk of sudden cardiac death. Patients affected by Brugada syndrome show electrocardiographic alterations either at baseline or after stimulation.
