Anyone wanting to revise the subject of heart murmurs should point their browser in the direction of Understanding Heart Tones www.co.gaston.nc.us/gemshp/training/heart-tones.htm. 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 www.nci.nih.gov/cancerinfo/pdq/cancerdatabase. 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 http://funsan.biomed.mcgill.ca/∼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 http://embryo.soad.umich.edu/index.html 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.
