A History of Bariatric Surgery: The Maturation of a Medical Discipline.

This article examines the progression of bariatric surgery since its creation more than 60 years ago with a focus on the effect of surgery on weight loss, comorbidity reduction, and safety. The success has been remarkable. It is possible to cure severe obesity, type 2 diabetes, and hyperlipidemia in addition to the many other manifestations of the metabolic syndrome with remarkable safety. Equally important are the opportunities for research afforded by the surgery and its outcomes. Until better treatments become available, bariatric surgery is the therapy of choice for patients with morbid obesity for weight control and comorbidity improvement.

The Watanabe heritable hyperlipidemic (WHHL) rabbit, its characteristics and history of development: a tribute to the late Dr. Yoshio Watanabe.

Professor Yoshio Watanabe, who developed the WHHL rabbit, died on December 13, 2008. He had contributed to studies of lipoprotein metabolism and atherosclerosis, and to the development of hypolipidemic and/or anti-atherosclerotic compounds. WHHL rabbits show hypercholesterolemia due to deficiency of LDL receptors, and very similar lipoprotein metabolism to humans. The incidences of coronary atherosclerosis and myocardial infarction in the original WHHL rabbits were very low. After three rounds of selective breeding, the coronary plaques changed to fibroatheromas with thin fibrous caps and myocardial infarction developed spontaneously. In studies with WHHL rabbits, plaque-stabilizing effects of statins were proved. In this review, we admire his achievements and describe the history of studies using WHHL rabbits.

Xanthelasma and lipoma in Leonardo da Vinci's Mona Lisa.

The painting Mona Lisa in the Louvre, Paris, by Leonardo da Vinci (1503-1506), shows skin alterations at the inner end of the left upper eyelid similar to xanthelasma, and a swelling of the dorsum of the right hand suggestive of a subcutaneous lipoma. These findings in a 25-30 year old woman, who died at the age of 37, may be indicative of essential hyperlipidemia, a strong risk factor for ischemic heart disease in middle age. As far as is known, this portrait of Mona Lisa painted in 1506 is the first evidence that xanthelasma and lipoma were prevalent in the sixteenth century, long before the first description by Addison and Gall in 1851.

Thematic review series: the pathogenesis of atherosclerosis. An interpretive history of the cholesterol controversy: part I.

This is the first of a series of reviews of the controversy that swirled around the "lipid hypothesis" of atherosclerosis for so many years. Today, in the era of the statins, there is no longer any doubt about the value of decreasing blood cholesterol levels. In fact, "the lower the better" is the position of many clinicians. However, getting to this point has been a long uphill battle marked by heated debate and sometimes violent disagreement. The history of this controversy is worth telling for its own sake and because remembering it may help us avoid similar mistakes in the future.

Insulin resistance and human disease: a short history.

The notion that tissue resistance to insulin might play an important role in certain disease states is approximately 60 years old. However, recognition of its central role in this regard is a relatively recent phenomenon. In this review an effort has been made to trace a brief history of insulin resistance from its inception to its current position as the fundamental abnormality in both type 2 diabetes and Syndrome X.
