Mono (a.k.a. Infectious Mononucleosis)

11 Oct

HPI:
–If they read the textbook, they come in with: fever, pharyngitis, adenopathy, fatigue, and atypical lymphocytosis, +/- splenomegaly.

DIAGNOSIS:
–Monospot test is helpful, doesn’t take forever to get
–EBV (Epstein-Barr Virus) stuff

SOMETHING I (re)LEARNED RECENTLY:
Elevated LFTs (liver function tests): very common in mono, but are self-limited
–If you have a pt with pharyngitis/feeling crappy, with elevated LFTs, let mono float through your differential

TREATMENT:
–supportive, symptomatic
–steroids controversial

GOOD ADVICE FOR PATIENTS:
–no contact sports for 3-4 weeks (highest risk of spontaneous or traumatic splenic rupture most likely 2-21 days after onset of symptoms)
