I discovered accidentially that if you use Google.com to search for a disease or ailment, a group of more specific searches appear first. These “result refinements” include

• Treatment
• Symptoms
• Tests/diagnosis
• Causes/Risk factors
• For patients
• For health professionals
• From medical authorities
• Medical alternatives

For example, if you look up bell’s palsy, you get this.

While there’s the risk of hypochondriacs making mischief with this service, I imagine on balance the result will be better patient information and more carefully directed health care for the savvy.
