Errors in Research Letter. The Research Letter titled “Microbiologic Assessment of Multidose Restylane for Facial Augmentation,” published in the July/August 2009 issue of the Archives (2009;11:271-273) contained several errors. The manufacturer of Restylane should have read Q-Med AB, not Q-Medical. The first sentence of the last paragraph of the “Methods” section should have read “For the final aspect of the experiment, 2 syringes of Restylane were seeded with 102 and 105 [rather than 102 and 105, respectively] colony forming units (CFUs) per milliliter of Staphylococcus epidermidis, respectively.” The last paragraph of the “Results” section should have read “In the vial seeded with S epidermidis, 102 [rather than 102] CFUs/mL, no bacteria were recovered after 6 hours. In the vial seeded with S epidermidis, 105 [rather than 105] CFUs/mL, the bacterial count notably decreased over the 24-hour time frame, and the final count at 24 hours was 60 CFUs/mL.” Finally, the last author's medical degrees should have included FRCSC and FACS, and his name was missing the first initial, “S.” S. Mark Taylor, MD, FRCSC, FACS, is the correct presentation.
