Metabolic syndrome: historical perspectives.
The metabolic syndrome is an aggregation of biochemical and physical conditions that presage the development of atherosclerotic cardiovascular disease. The history of the metabolic syndrome is rooted in the recognition of adipose tissue as a heterogeneous, biologically active organ, as well as in the concepts of insulin resistance and its consequences. Establishment of the metabolic syndrome as a disease entity has been hindered by non-uniform criteria for its diagnosis.

Austin Flint in New Orleans and the origins of evidence-based medicine.
The famous nineteenth century American physician and medical educator, Austin Flint, Sr., was a professor at the New Orleans School of Medicine and a visiting physician at Charity Hospital in New Orleans from 1858 to 1861. Best remembered for the heart murmur that bears his name, Flint was also responsible for advances in the diagnosis and treatment of infectious diseases in the era that preceded the germ theory and the discovery of antibiotics. His experiences at Charity Hospital and his exposure to the French style of medicine as practiced by the Creole physicians of New Orleans encouraged him to advocate conservative treatment for pneumonia, in contrast to the bloodletting and other heroic measures that were popular at the time. His recommendations, based on statistical analysis of his clinical data from Charity Hospital, were one of the earliest examples of evidence-based medicine in America.

The Ashman phenomenon.
In the presence of atrial fibrillation, impulses of supraventricular origin that are transmitted through the ventricles during periods of relative refractoriness to impulse conduction exhibit anomalous configurations. These "aberrant beats" can be difficult to distinguish from ventricular ectopic beats, and groups of aberrant beats may be mistaken for ventricular tachycardia. Richard Ashman, PhD, a physiologist at Louisiana State University School of Medicine in New Orleans, noted that ventricular refractoriness varied with the lengths of cardiac cycles; that aberrant beats typically ended short cycles following long cycles; and that aberrant beats often have a right bundle branch block configuration. This observation, known as the "Ashman phenomenon," has become a principle of cardiology. Its recognition may allow clinicians to distinguish aberrant beats from ventricular ectopy. Ashman made a variety of other fundamental contributions to electrocardiography and was also an accomplished poet.
