In an undiagnosed case of hemorrhagic disease in China, Marjorie Pollack, a ProMED editor, used GIDEON to help figure out the differential diagnosis. From the ProMED note:

Using the database of the Global Infectious Disease and Epidemiology Network (GIDEON ) to see possible etiologies for a hemorrhagic fever syndrome in China, the most likely diagnosis would be Old World hantavirus infection (57 percent probability), followed by _Streptococcus suis_ infection (40 percent), leptospirosis (1.8 percent) and Crimean-Congo hemorrhagic fever (CCHF — less than one percent probability).

In 2005 an agricultural expert from Israel went for 6 days to India to participate in a farming project. He returned to Israel, and the following morning developed fever, headache, vomiting and muscle pain. Read the latest case of the month, Agriculture Expert in India, about how GIDEON helped save this person’s life.

Diagnosing a patient has just become easier with our latest feature, symptom images. As you mouse over any of the symptoms in the Diagnosis module, the signs and symptom description will display a representative photo or image. This will provide an additional visual differentiation of similar symptoms, further enhancing GIDEON diagnosis. See the example of the description of Jaundice to the left.

As a result of feedback from our users, we’ve added ICD9 and ICD10 codes to Diagnosis symptoms and the Epidemiology diseases.

In the Diagnosis module, the mouse-over description for symptoms will display the code, if available. For example, to the left is the description for “Jaundice”.

The General tab of diseases in Epidemiology will display the ICD9 and ICD10 codes below the list of disease synonyms. Synonyms and codes for Babesiosis:

The codes have been integrated both into diagnosis and text search. So if you want to diagnose an infectious disease based on the ICD9 and/or ICD10 codes for symptoms, just enter them in diagnosis search and click the button.

Likewise if you’re searching for a disease based on the ICD9 or ICD10 code, enter the code in text search and click.

Ever since we launched the web version of GIDEON, our CD customers have requested that in Diagnosis and Microbiology Identify, marking symptoms and tests should enable the right click to select “no”.
Well finally this now works. Left click will rotate from Yes to No to blank. Right click will rotate in reverse from No to Yes to blank.

ProMED provided another great example of how GIDEON can be used to diagnose an illness in Cote d’Ivoire:

When one checks GIDEON (Global Infectious Disease and Epidemiology Network) for the clinical picture associated with contact with animals, one gets 3 main possibilities — Q fever, ornithosis, and bunyaviridae. Of the bunyaviridae family, one does think of Rift Valley fever (RVF) as consistent with this clinical picture, but the involvement of poultry rules this out, as the RVF virus does not affect avians. Gideon also gives a “1st case scenario”, where it “ignores” the geographic location of the outbreak in the event that this is a new geographic extension of an otherwise known pathogen. In this case, the GIDEON program suggested Congo-Crimean hemorrhagic fever (CCHF).

We just launched a great new feature, Diagnosis search. This provides for an alternate method for entering signs, symptoms and country of acquisition. You can just type them, or their synonyms. See the Getting an Itch on Bali case of the month, or watch the video.

A new feature has been added to diagnosis result to help diagnose “first cases” of a disease which has never before appeared in a given country. See “The First Case” Scenario case of the month, or watch the video.

The BioTerror indicator feature displays an indicator next to potential bio-terror diseases in any differential diagnosis.

This feature extends the Bio-terrorism module functionality to alert users that may not suspect Bio-terrorism when performing a diagnosis.
