Science, Anatomy, and Art: Revisiting Leonardo da Vinci, Pioneer of Modern Anatomy.
Leonardo da Vinci, the artist and scientist, was an archetype figure of the Renaissance era. He was an autodidactic polymath in natural sciences, engineering, and physical sciences, imbued with universality, prodigious inventive imagination, and curiosity to know and understand the world around him. Among his myriad activities, anatomy, physiology, and biomechanics of the musculoskeletal system and the underlying systems fully engaged him. ⋯ The contribution of preceding anatomists is reported as a source of his inspiration as well as motivation to successors. Leonardo da Vinci left no publications, but rather an extensive collection of personal notebooks. Leonardo's contribution to modern anatomy was enormous and he is considered by the scientific and medical community as the father of the modern anatomy.

Extra peritoneal packing (EPP) is a quick and highly effective method to control pelvic hemorrhage. ⋯ EPP is equally effective when performed in the ED or OR with similar surgical site infection rates but higher incidence of DVT.

An arginine-rich apolipoprotein was discovered 50 years ago and became known as apolipoprotein E (ApoE) 10 years later. ApoE is associated with triglyceride-rich lipoproteins and mediates the clearance of these lipoproteins from the plasma. The ApoE-deficient hypercholesterolemic mice are an excellent platform for experimental atherosclerosis because they are similar to human pathology with regard to an atherogenic diet. ⋯ ApoE4 substantially increases the risk including age of onset, progression, and prognosis of Alzheimer's disease. Therefore, much effort has been directed to the elucidation of the pathogenic role of ApoE related to amyloid β (Aβ) acquisition in the brain. The ApoE trail passing from an enigmatic protein to a major player in cardiovascular and neurodegenerative disorders is reviewed.

Iron deficiency anemia is a widespread problem. Although oral and intravenous therapy are available, iron malabsorption is a distinct possibility. ⋯ The oral iron absorption test, although not clearly standardized, is easy to conduct in any outpatient clinic. This test can readily and clearly determine absorption or nonabsorption of iron. This test can have major implications on the need of oral or intravenous iron therapy and can also determine the need for further gastrointestinal evaluation of the small intestine, where iron absorption takes place and the success of therapy on subsequent iron absorption.

Rheumatoid arthritis (RA) is a chronic inflammatory and destructive joint disease with the presence of autoantibodies, rheumatoid factor (RF), and anti-citrullinated protein antibodies (ACPA). The presence of RF or ACPA predicts RA severity. Data on the influence of ACPA titer on RA course are limited. ⋯ Titer of ACPA was not identified as a predictive factor for RA severity.
