I want to find patients with the following criteria:
1. Patients who have been diagnosed with Essential (prim@21:09:26
2. Patients who have been diagnosed with Essenti-Diabete@21:17:50
3. Patients with a masterid of 4159, 4164, and 4163 in their medical records
4. The query is not restricted by specificity or timing, so it will include all occurrences of these criteria in the patient's medical history.
