Lyme Disease

A
  • Most commonly caused by Borrelia burgdorferi carried by Ixodes tick
  • History of being in the woods, hiking, or camping

**Sx
* Stage 1: erythema migrans (pathognomonic), viral-like syndrome (fever, fatigue, malaise, myalgia, headache)
* Stage 2: myocarditis, bilateral facial nerve palsy (pathognomonic for Lyme disease)
* Stage 3: chronic arthritis, chronic encephalopathy
* PE: slightly raised red lesion with central clearing, erythema migrans (bull’s-eye) rash

**Tx: doxycycline
* Children: amoxicillin or doxycycline (if used for < 21 days)
* Pregnant: amoxicillin

**Prevention after tick bite - doxycycline 200 mg in a single dose if:

Q

Clinical presentation: A 1-year-old presents with intermittent abdominal discomfort and a palpable sausage-shaped mass in the right mid-abdomen.

What is the most appropriate therapeutic course of action?

Study These Flashcards
A

Air insufflation or barium enema (BE)

These studies are useful both diagnostically and therapeutically since 90% of intussusception cases may be corrected if it is performed within the first 12-24 hours.

Note: Ultrasound should be the first diagnostic tool if the diagnosis is ambiguous.
