Andreas Vesalius' 500th anniversary: the initiation of hand and forearm myology.

UNLABELLED: Andreas Vesalius (1515-1564) was the first to market an illustrated text on the freshly dissected muscular anatomy of the human hand and forearm when he published his De Fabrica Corporis Humani Libri Septem, in 1543. To commemorate his 500th birthday, we searched the second of seven books composing De Fabrica, the annotated woodcut illustrations of De Fabrica, the Tabulae Sex, and Epitome, and an eyewitness report of a public dissection by Vesalius for references to the morphology and functions of these muscles. We found Vesalius to have recognized all currently distinguished muscles except the palmaris brevis and he noted occasional absence of some muscles. Generally, he limited the origin and insertion to bones, largely disregarding attachments to membranes and fascia. Functionally, he recorded the muscles as having a single vector and operating on only one joint. We conclude that Vesalius was nearly completely correct about the anatomy of the muscles of the forearm, but much less accurate about their function. LEVEL OF EVIDENCE: 5.

Immunization after renal transplantation: current clinical practice.

BACKGROUND: The use of potent immunosuppressive drugs and increased travel by renal transplant recipients (RTR) has augmented the risk for infectious complications. Immunizations and changes in lifestyle are protective. The Kidney Disease: Improving Global Outcomes (KDIGO) Transplant Work Group has developed guidelines on vaccination following solid organ transplantation. The degree of adherence to these guidelines is unknown, as is which barriers must be overcome to improve adherence. METHODS: We performed a cross-sectional national survey among Dutch nephrologists to assess vaccination policy and adherence to the KDIGO guidelines. In addition, to investigate awareness and attitude of RTR regarding their risk of infection, we performed a cross-sectional survey of RTR in our outpatient clinic. RESULTS: A total of 132 (63%) nephrologists completed the survey. Reported immunization rates were 90.8% for influenza and 27.3% for hepatitis B. However, pneumococcal, tetanus toxoid, and meningococcal immunization rates were low. Twenty-seven percent of respondents were familiar with the guideline contents. The most frequent perceived barrier to guideline adherence was expectation of low effectiveness. A total of 403 RTR (62%) completed the survey. Sixty-eight percent perceived more risk for complicated infection. A significant correlation was found between education level and variables concerning awareness and attitude toward risk of infection. CONCLUSIONS: Our results show that nephrologists' knowledge of and adherence to the recommendations regarding immunization after renal transplantation is suboptimal. Most Dutch RTR are aware of their increased risk and the possible seriousness of infectious complications. However, their behavior does not match their awareness. This disparity points to an important role for nephrologists in providing adequate counseling.
