How To Use Connectance

Suppose a physician has a 12-year old male patient who was noticed by his mother to have unusually low set ears and perhaps some degree of hearing impairment. A physical examination of the patient reveals low set ears and lenticonus. The patient's height and weight are as follows – Height: 68 inches; Weight: 150lbs.  Lab results are as follows – Aminoaciduria: present; Audiometry: abnormal; Proteinuria/Day: 0.40;  and Urine RBC: 5. What’s the possible diagnosis?

From the “My Account” page, click on either the New Exam or Patient History tab.  Clicking on either one brings you to the following page:


Begin by filling in the information.  If you would like, fill in the patient name and record number. These are for your files only and not required fields.  Move on to step 2, and complete history and physical information as you would for any patient:
Next, fill in the patient’s age, height, weight, and sex:


Finally, fill in the patient’s lab results and imaging (if available).  Clicking on the Add/Edit Lab Results button opens the following window:


Navigate to the appropriate lab test using either the alphabet at the top of the list or the arrows located after every 15 tests.  Remember to click on the submit button at the top or bottom of the list to record your results once you have finished entering all the results.  After you click on the submit button a summary of the patient’s lab results are provided on the patient history page as follows (those results in red are outside of what is considered normal):

To delete a lab test, click on the trash can icon next to the test.

To see a diagnosis, click on the similarity index button.  The software first checks to make sure all required fields are filled in and a spell check is conducted.  The similarity index is then calculated and presented.  At the top of the page you will see the following results:



Here, the patient’s case is 61% similar to Alport Syndrome, 22% similar to Fanconi Syndrome, and 17% similar to Acute Renal Failure.  Two related possibilities are also presented.  Information on Alport Syndrome is presented below the similarity index as follows:

You can either scroll down the page for the information or use the links for clinical features and remarks, laboratory findings, management, suggested tests, images, biopsies, and a disease bibliography provided through PubMed.  To see this information for other diagnoses in the similarity index, click on the detail button next to the diagnosis.

To edit the case, click on the patient history tab.  You will return to the page containing the information you completed on the patient.  To print your results, click on the print icon.  To start a new case, click on the new exam tab.

If you are interested on doing research on a particular disease and do not want to calculate a similarity index, click on the treatment library tab.  Here you will find information on all of the diagnoses in our database.
