The continuing education courses found on our website have been compiled from many sources. They are intended to be a study and review guide, not a comprehensive text. We have attempted to provide acknowledgment of sources, but there are likely several that are not specifically mentioned. The continuing education programs were as accurate as possible at the time of publication. It is possible that errors exist, or that currently accepted medical practice may have changed. Neither the authors, their respective institutions, nor any other individual or institution, except the person using these programs, is responsible or liable for any consequences of its use. The authors actively encourage corrections and comments, and will annotate the programs accordingly.
