Effective communication with patients
 19 yr old college student with c/o headache, has
called the office asking for pain medication. In
high school, he used to take his mom’s headache
medications, what is your recommendation?
 1) have him take an Aspirin and call back if no
improvement
 2) have the nurse call and find out name of mom’s pain
med
 3) have the patient come in the next available appt, in 2-3
day
 4) obtain more information
 He has been up studying for exam all
night now he has neck stiffness, feels
tired and can not concentrate, he feels
warm, there is no AC at his dorm
Meningitis
 Triad of:
 Nuchal rigidity ( 88%),
 sudden high fever of 38 degree( 95%)
 altered mental status, confusion, lethargy(78%)
 Triad present in 44-46% of cases
 99% of cases have at least one of the 3
 Absence of the 3 excludes meningitis
45 year old presents with sudden
onset sever explosive headache,
worst headache of his life
Thunderclap headache
 Sever, sudden, explosive, unexpected
 Similar to clap of thunder
 Maybe associated with brief loss of
conscious
 May have Nausea, vomiting, meningismus
 Exacerbated by physical exertion
 What is the first step in evaluation of patient who
present with thunderclap headache?
 1) call neurology
 2) CT without contrast
 3) CT with contrast
 4) MRI
Computed Tomography
 CT without contrast
 To confirm or exclude bleeding
 Fast, easy, available and cost effective
 If negative CT  Lumbar puncture
 72 yr old female was brought in by her family,
reporting that she is acting depressed, has lost weight
due to not eating, can not sleep at night, looks tired
during the day, and complaining of headache.
 1- Treat depression with amitriptyline, it will also help
her headache
 2- Prescribe mirtazepine to help her sleep, it may
improve appetite
 3- complete history and exam, check blood test
including CBC, Sed rate, CRP
Temporal Arteritis
 Age 50 ( mean age onset 72)
 Temporal headache that can wax and wane
 Abrupt onset of visual disturbance

underlying disease
