E-book: Infectious Diseases of Haiti by GIDEON

When the humanitarian disaster in Haiti began to unfold, we accelerated development of a comprehensive book on the diseases of that country. This will be one in a series of ebooks which present the status of all infectious diseases…in all individual countries. This ebook, Infectious Diseases of Haiti, will be offered free of charge to all health professionals concerned with the current disaster.

There are 347 forms of human infectious disease in the world today – and 198 of these (more than half) are known to occur in Haiti. Sadly, one of the “side effects” of living in a poor and disaster-ridden economy is a lack of useful facts regarding the local status of individual diseases. GIDEON (Global Infectious Diseases and Epidemiology Online Network) is a Web-based application which follows diseases – both on a global level and within each country. Data are updated daily and are derived from all relevant journals, websites, Health Ministry reports and publications of the World Health Organization. The electronic book (ebook) is generated from information in the GIDEON database, and will serve as the first comprehensive review of infectious diseases in Haiti. Similar ebooks are now available by country and disease.

New GIDEON Diagnosis Module Video

Following up on the post announcing the new GIDEON diagnosis module, there is now a video demonstration by Dr. Steve Berger:

Wishing you all a happy 2010!

New GIDEON Diagnosis module

GIDEON’s redesigned Infectious Diseases Diagnosis module has been launched (screenshot). There are many new features, including

  • Suggestions
  • Dynamic diagnosis
  • Usability improvements


Diagnosis suggestions snapshotUntil now, GIDEON’s Diagnosis Compare function has ranked signs and symptoms which are most likely to impact the Differential Diagnosis list. Now, the top four clinical findings which are most likely to focus and shorten the list of possible diseases are displayed and dynamically updated as each new sign or symptom is entered. Clickable boxes which allow the user to enter a “yes”, “no” or “unknown”, appear and enlarge each time the mouse passes near a perspective finding.

Dynamic diagnosis

The Diagnose button has been eliminated! Now, the differential diagnosis list updates automatically as you enter signs and symptoms. This feature demonstrates the effects of each new sign or symptom as it is entered.
The First case scenario list still appears below the diagnosis list.
Diagnosis results buttonsThe familiar buttons: Compare, Why Not, Open case, Save case, Remove All, Print, Email are all in the Diagnosis Results area.

Usability improvements

Country selection and Incubation period entryCountry and incubation period in symptom list
Country name and Incubation period have been appended to the Clinical Presentation list.  Now, whenever you indicate a country name, or dates of exposure, the Differential diagnosis list instantly re-adjusts accordingly.

Collapsible windows
Windows, such as Suggestions and Clinical Summary can be minimized and hidden. For example to not see suggestions, click on the minimize button Minimize button to the left title.

Mouse overs
Mouse over check boxMore mouse-overs have been added: Clickable boxes expand as you mouse over them, and display clear symbols to select “yes” or “no.”

Clinical Summary
You can now click on the signs and symptoms in the Clinical Summary. Clicking on Country will display “Worldwide”. Clicking again displays the country.

Quick sorting
Probability sort arrowDiagnosis results can be sorted alphabetically or by probability easily by clicking the column title.

Resize window
Changing vertical window size expands size of Clinical presentation and Diagnosis results sub-windows. This is a great feature for larger monitors.

Previous version
Click “Original diagnosis” to use the older interface.

Compare diseases, drugs or pathogens

One of the most important functions of GIDEON is to help users prepare scientific articles, teaching material and other publications (see the Fingerprint case of the month). A new feature now allows users to create custom-designed charts which compare the features of two or more diseases, drugs or pathogens.

For comparison of key clinical and epidemiological features of infectious diseases, in the Diseases tab, click on a disease (step 1 in the image below), and – while holding down the control button – click on other diseases of your choice. Now click on the Compare button (step 2).

Linking between modules

We’re continuing our progress in making it easier to find the information you’re looking for in GIDEON with minimal effort. We have added a new feature in the Microbiology module that link relevant organisms to their drug susceptibility and appropriate vaccines as demonstrated by the highlighted links in this screen shot of the Vibrio Cholerae general tab:
Microbiology Vibrio Cholerae information
These new links are in addition to links added in the past connecting between disease organisms to microbiology and typical therapy to drugs, vaccines and pathogens.
For example see the links from the Anthrax disease general information tab screen shot below, to the Microbiology organism (Bacillus anthracis), Therapy (eg: Ciprofloxacin) and Anthrax vaccine:
Anthrax general disease information

Pre-travel feature enhances GIDEON for Travel Medicine

Infectious Diseases – Travel

Traditionally GIDEON has been used by Travel Medicine practitioners, who have loved the detailed country information for the various diseases affecting travelers. Their main suggestion was to add more pre-travel information that could be provided to travelers at consultations. We’re happy to announce that we listened and have now launched a new Travel tab in the Infectious Diseases module.

The left side of the Travel section includes the general Region of travel in the upper box, and specific countries in the lower box:

Selecting a specific country lists relevant information in the right-hand column of the Travel section.   The general pre-travel information is provided by region and is divided into Professional, Traveler, and Diseases sections:

The Professional tab is for health practitioners and is based on content from the CDC Yellow book. Links are provided directly to relevant disease information in GIDEON:

The Traveler tab is traveler friendly content from the CDC Traveler’s health destination guide. Links are provided to additional information from the CDC:

The Diseases tab displays the list of all the relevant diseases that have additional information for travelers to the selected country. The content is presented briefly as a “mouse over” and can be accessed more thoroughly by linking to actual country note for the specific disease:

As with all the information in GIDEON, you can print and email each section information. This will be very useful to serve your travelers that want a hard copy of the information or a soft copy via email.

“Traveling with GIDEON” is a new case of the month that demonstrates how to use the Travel tab and includes a video.

Easier diagnosis with symptom images

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.

ICD9 and ICD10 codes added

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, the description for “Jaundice”:
Jaundice symptom description, with ICD9 and ICD10 codes

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:
Babesiosis synonyms and ICD9 and ICD10 codes

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.

Microbiology Text search

One more feature enabled by the microbiology module makeover is support for text search. Search results for organisms will show up in regular text search. Now you can search for all GIDEON main keywords from the text search box, unifying all the information.
We have some more work: index all the text and images and maximize the value of search in GIDEON.
