For whom is this online service?

For a doctor if he:

  • conducts differential diagnosis for a combination of diverse symptoms.
  • applies a systematic approach in the diagnostic search to treat the patient, not the disease.
  • did not find pathology in the patient according to his profile and wants to tell him the direction for further examination.

For the patient if he:

  • he walks in circles on specialists, and they only shrug in bewilderment.
  • unsuccessfully examined or treated for a long time
  • repeatedly consulted by doctors, but does not have an accurate diagnosis, needs advice, what else can be excluded to establish the causes of the disease state.

Even if the patient already has many correct diagnoses, the root cause of all diseases sometimes no one knows.

For example, a patient with Sjogren`s disease can be treated for many years:

-orotinolaryngologist from atrophic rhinopharyngolaryngitis and sinusitis,

-oculist from keratoconjunctivitis,

-dentist for sialadenitis, caries and stomatitis,

-neurologist from neuropathy,

therapist for tracheobronchitis, cholecystitis and atrophic gastritis

All diagnoses are correct, but the true reason for this bouquet is Sjogren`s disease, which remains undiagnosed in half the cases.

Why Etiona if the patient has already been examined many times?

In the legend, blind sages touched only 1 part of an elephant and each described it in their own way. Medicine looks similar.

The doctor has the right to diagnose only what is within the framework of his specialty, he is limited by the short time of reception, the equipment of the office and the capabilities of his human memory, as a result, the diagnoses that lie on the surface are more often established. Attempts to look deep into the dynamic picture of the disease are rare.

Etiona - this is perhaps the most affordable opportunity to analyze all the heterogeneous symptoms of the patient at once and see what can be hidden behind it, the program in its logical conclusions will take into account the knowledge of thousands of diseases at the same time.

Look at the disease wider, see the `medical elephant` entirely with Etiona!

the disease is similar to an elephant, which everyone described in parts, but as a whole, no one saw

Why, if there is an Internet search engine?

Etiona in a couple of minutes will find many options for the causes of the disease for differential diagnosis, saving you the time that you could spend on an independent search in hundreds of articles issued by the Internet search engine.

From the rendered graph, you can easily understand why the program showed you this or that result: Etiona will translate the scientific terms into descriptions understandable to any person, will take into account the possible etiopathogenetic transformations and for your convenience will highlight all the significant nodes in the response in different colors, in accordance with their role in the picture of pathology

Etiona will hypothesize the development of the disease, even if a similar case has not yet been described in the literature.

When creating each answer graph, scientific knowledge obtained immediately from many medical sources will be simultaneously applied.

Artificial intelligence will apply the knowledge gained from millions of books in order to help solve your diagnostic puzzle.

Other benefits of Etiona:

A few vivid symptoms are enough

No hourly questionnaires from hundreds of complex clarifying questions.

Huge selection of complaints and illnesses

When creating a request, you have access to a list of ~ 6000 symptoms and diseases (growing regularly)

Symptoms understood by you.

You can include in your question both simple complaints that the child understands and complex medical terms.

About program device

"Etiona" calculates the possible causes of the disease, generating causal chains from the known etiopathogenetic relationships. At the moment, the memory contains information about only a small part of the diseases existing in the world. But the database of the program is updated regularly and what was not found today may be found next time.

The service may be useful today if you are looking for the reasons why the following symptoms and diseases appeared: fever, anemia, chest pain, heart pain, rash, joint pain, jaundice, shortness of breath, nausea, vomiting, increased blood pressure , tachycardia, diarrhea, constipation, decreased appetite, bleeding, runny nose, nasal congestion, weakness, pneumonia, cyanosis, renal failure, increased triglycerides, enlarged spleen, enlarged liver, enlarged lymph nodes, nosebleeds, headache, itching, th dizziness, cough, abdominal pain.

Work examples

( Do not forget to watch the video demo before starting your independent work)

Option: The roots of the symptoms

Find out what can cause weakness and chest pain.

We`ll go to the facts entry page by clicking on the green button with the inscription `Try it yourself!`

Step 1

Make a list of facts to create a question.

We`ll select and enter the symptoms to be examined in the list. At the end, press the green button with the inscription `Find out Etiona`s answer`.

Step 3

Narrow down the diagnostic search.

Each disease or link in the pathogenesis may have other manifestations. Some of these possible consequences/symptoms can be seen by double-clicking on the node of interest. In the window that appears, select the features that also occur in this case by clicking on the blue cross at the end of the desired line. For example, add `suffocation` and `cough`. After viewing the entire list, click the blue button `close` at the bottom of the window.

Step 4

Get the second sorted answer.

If additional symptoms were noted, then Etiona will redraw the graphs taking into account the newly marked signs, the path from the cause to the newly entered symptom will appear where it is possible with sufficient probability. Having finished searching for additional symptoms, click on the green button `new question` and in the next answer, Etiona will sort the graphs depending on the number of matching symptoms.

Conclusion:

For some combination of symptoms, hundreds of disease options will be possible.

Note the pathologies that have the highest number of matching symptoms and are drawn by short cause-and-effect chains. If after pressing the `new question` button, the list of additional symptoms is not deleted, then in the newly issued answer, Etiona Will place such diseases at the very beginning of the queue of graphs, sorting his answer in the order of occurrence of the given symptoms with the maximum probability.

As a result, You will be able to select several variants of diseases for priority confirmation (or exclusion) by narrow specialists.

Option: All the causes

Find out the closest possible causes of the symptom of "suffocation"

Similarly, go to the "Options" tab, and then select the "All reasons" option

Step 1

Enter the fact of interest

Selecting a fact from the drop-down list, click on the button 'Find out Etiona`s answer', after which we will wait for the answer to be drawn

screenshot of symptom input window

Step 2

Get the answer.

The response graph consists of the fact you entered (the pink center node) and the set of its immediate causes (blue nodes).

gif from screenshots of part of the program response

Conclusion:

You should analyze all the possible causes. It is necessary to exclude or confirm the importance of these reasons in each case together with a specialist doctor. Those reasons that were confirmed by the results of examinations by medical workers, in turn, must be reanalyzed for reasons already for them, and so on until the dynamics of the development of this symptoms becomes fully understood.

Option: All the consequences

We find out all the nearest possible consequences for the disease "Candidiasis"

Similarly, go to the "Options" tab, and then select the "All effects" option

Step 1

We introduce the fact of interest

Selecting a fact from the drop-down list, press the button 'Find out Etiona`s answer', after which we will wait for the answer to be drawn

screenshot of symptom input window

Step 2

Get the answer.

The response graph consists of the fact you entered (the node of the blue center) and the set of its immediate consequences (nodes of the pink color).

gif from screenshots of part of the program response

Conclusion:

Consider all the possible consequences. Even if the patient confirms the diagnosis of candidiasis, only a small fraction of the symptoms listed in the column may be present. Conversely, even if part of the consequences coincided with the patient's symptoms, this does not mean that he has candidiasis. It is necessary to exclude or confirm the presence of the disease in each case with a specialist doctor.Consider all the possible consequences.

Conversely, even if part of the consequences coincided with the patient's symptoms, this does not mean that he has candidiasis. It is necessary to exclude or confirm the presence of the disease in each case with a specialist doctor.

Option:Causal Chain

Consider all the possible consequences. Even if the patient confirms the diagnosis of candidiasis, only a small fraction of the symptoms listed in the column may be present. Conversely, even if part of the consequences coincided with the patient's symptoms, this does not mean that he has candidiasis. It is necessary to exclude or confirm the presence of the disease in each case with a specialist doctor. "flu" and consequence "vomiting".

Similarly, go to the "Options" tab, and then select the "Causal chain" option

Step 1

Let us introduce the cause and effect of interest

After filling out each field with a fact from the drop-down list, click on the button 'Find out Etiona`s answer', after which we will wait for the answer to be drawn

screenshot of symptom input window

Step 2

Get the answer.

Each of the chains of causal relationships in the answer contains: the cause is a yellow node, the consequence is pink, between them are intermediate nodes of pathogenesis.

gif from screenshots of part of the program response

Conclusion:

Consider all the drawn causal chains, to switch between them, use the "forward" and "back" buttons. You should analyze all intermediate nodes in the chains. For some cause-effect pairs, several correct cause-effect chains are possible at once. Confirm or exclude their importance for this patient with a physician competent in this matter.

Option: Targeted search

We will find the reasons for one of the symptoms, taking into account the remaining symptoms. Find out the possible causes for the main symptom "fever of unknown origin" and additional symptoms "jaundice" and "diarrhea".

Similarly, go to the "Options" tab, and then select the "Target search" option

Step 1

We introduce the available symptoms in any order

Having compiled the list, press the appeared button 'ask a question' located to the right of the symptom that we assign as the main one in this request, after which we will wait for the answer to be drawn

screenshot of symptom input window

Step 2

Get the answer.

Each of the drawn graphs contains a possible cause (yellow node), the main symptom (orange node), additional symptoms (pink nodes) and intermediate pathogenesis nodes (blue and violet nodes)..

gif from screenshots of part of the program response

Conclusion:

Consider all the drawn graphs, to switch between them use the "forward" and "back" buttons. Not all of the additional symptoms may be related to a possible cause, such nodes may have their own independent reasons not drawn in this request. To find the reasons for the unconnected nodes, repeat the query, choosing another symptom as the main symptom. You should analyze all the intermediate nodes in the graphs. For some symptoms, several correct reasons are possible. Confirm or exclude their importance for this patient with a physician competent in this matter.
