    • Anyone wanting to revise the subject of heart murmurs should point their browser in the direction of Understanding Heart Tones The site offers a succinct review of the cardiac cycle and auscultation in an emergency situation, and the final section has snippets of heart sounds. There is a good description of each murmur followed by the sounds themselves. Speakers will be needed, but the clarity of the sound is excellent.

    • The US based National Cancer Institute has created a comprehensive database that includes peer reviewed summaries on cancer treatment, screening, prevention, genetics, and supportive care, and complementary and alternative medicine Known as PDQ (physician data query), the database has sections on both adult and paediatric treatment summaries, as well as a section on prevention.

    • Those seeking help in designing presentations—something that many healthcare professionals are increasingly finding themselves having to do—may wish to visit a Canadian site that offers an introduction to presentation software∼funnell/InforMed/Bacon/Present/pres.html. With so many programs to choose from and so many ways to design electronic slides, the message to be communicated can easily be overlooked. But this site offers a guide through the software jungle, as well as some useful design and organisation tips.

    • Embryology can sometimes seem a long forgotten topic, last visited at medical school, but it is the kind of subject that can be brought alive on the internet. A good example is a site from the US National Institute of Child Health and Human Development. The Multi-Dimensional Human Embryo has made available a three-dimensional image reference based on magnetic resonance imaging (MRI). Growing embryos are depicted in advancing stages of maturity; by clicking on the images users can choose levels of an MRI slice. Also on offer are animations in the form of QuickTime files.

    • For an excellent collection of articles about pain visit the Oxford Pain Internet Site, which has been produced by the Bandolier evidence based healthcare group. Subject areas include cancer and chronic pain, arthritis and perioperative issues.
