Dealing with abbreviations - search with them or spell it out? For example, h pylori or helicobacter pylori; MALT or mucosa-associated lymphoid tissue? Abbreviations like these two, because they are so well known, will give you pretty good results, but often, searches will be better with the full phrases than the abbreviations. Be prepared to search again with a the full term whenever you search with abbreviations and the results seem limited.

Search Tips -- PubMed & EBM using PICO
Accessss - an EBM federated search tool
DDX & Symptom Checkers (reminder) -- a tip from Dr. Gates
MedlinePlus -- Fruit & Veggie Resources
PubMed can help you answer the question about diagnositc tools for h pylori. This case is also a great example of using the PICO format for structuring your query.
PubMed via the PICO tool:
(Great when you use all the Comparisons)
Patient (details) --- 60 yo female, possible h-pylori infection
Intervention (pick one) -- urea breath test
Comparison (list one or all) -- serology OR stool
Outcomes (optional this time) -- diagnosis
Although recent changes have made using abbreviations much more successful, a search in PubMed is better when you use the full spelled out version instead of its abbreviation, so your terms will be something like:
helicobacter pylori diagnosis urea breath test stool
Depending upon your question - do you need evidence from Clinical Trials or do you want a bigger picture with Review articles - you could limit it further with a filter for either a Clinical Trial or Review.
You will get a short list of potential articles - this topic has been particularly well discussed in 2014.
ACCESSSS - Search Across Multiple Clinical Resources
Ever wish there was something like Access Medicine for some of those clinical tools? Well, we have partnered with the people at McMaster to use their search tool called ACCESSSS. Give it a shot this week and let me know how you liked it. It is new for me too, so any comments you have for me are helpful. You will need to create an account to use this tool.
Need an example? Try the PubMed search above and see what you get.
Symptoms and differential diagnositic information is often buried in a number of our resources. However, a few tools (both online and for your smart phone/PDA) have special tools to help with this process.
Dr. Gates has found a very helpful text within Access Medicine - Symptoms to Diagnosis: An Evidence Based Guide. Presented through a series of cases of patients complaining of a specific issue, then walks you through buiding the DDX and prioritizing it, and making the diagnosis. Unlike the interactive tools that give you list, . Topics include a variety of non-specific complaints from low back pain to weight loss to GI bleeding, to abdominal pain. Check out Chapter 1 as an overview of the diagnostic process.
The books we have include one that helps explain the thinking process (Symptom to Diagnosis) with topics that include a variety of non-specific complaints from low back pain to weight loss to GI bleeding, to abdominal pain. One book has a list of mnemonics (Collins' book) as well as the symptom info. Another book (Syed & Rasul's book) is organized by body areas and the last one (DDX of Common Complaints) focuses on the most common symptions and presents the way a doctor might pursue to diagnosis (images & tests).
Also listed below are some of the interactive DDX tools and their advantages.
Online Look-up Tools
