1) Distinguish between acute otitis media (AOM) and otitis media with effusion (OME) in making therapeutic decisions.

=> An AOM is an acute otitis media. An OME is an otitis media that is associated with an effusion. An AOM must be distinguished from an OME by every physician that makes a therapeutic decision.

=> An otitis media that is associated with an effusion must be distinguished from an acute otitis media by every physician that makes a therapeutic decision.

2) Clinicians should exclude other treatable, reversible causes of change in mental status before a diagnosis of HIV-associated dementia (HAD) can be made.

=> A cause X of a change that is in a mental status is found at a time T1. A diagnosis of a dementia that is associated with HIV is made at a time T2. If X is treatable and reversible then T2 must be smaller.

3) The primary care clinician should instruct patients and caregivers on how to maintain oral hygiene.

=> If a person X follows a procedure Y then an oral hygiene of X is maintained. If a person X is a patient or a caregiver of a primary care physician Z then the primary care physician W must instruct the person Z on the procedure Y.
