Title: I found a tick on my kid! <br/>Author: Rose Chasm<br/><a href='http://umem.org/profiles/faculty/82/'>[Click to email author]</a><hr/><ul>
<li>
The rainy East coast spring has increased tick populations in endemic areas such as Maryland resulting in more tick bites.</li>
<li>
ED visits for known tick bites present acutely, often with parents bringing in the tick to be identified/tested.</li>
<li>
Routine serologic testing and antibiotic prophylaxis is not recommended after every tick bite.</li>
<li>
If an attached tick is <strong>engorged, </strong>identified as <strong>I. scapularis, </strong>and has been attached for <strong>>36 hours, </strong>then antibiotic prophylaxis for Lyme can be prescribed if started within 72 hours of tick removal in those patients<strong> > 8 years of age</strong></li>
<li>
Prophylaxis: Single dose of doxycycline 4 mg/kg or 200mg max </li>
<li>
If early Lyme Disese is present in the form of the classic rash of Erythema migrans, then treatment is doxycycline, 4 mg/kg or 100mg max BID for patients > 8 years of age or amoxicillin 50 mg/kg per day divided TID with 500 mg max TID in those < 8 years of age for 14 days </li>
<li>
Serologic testing is false negative in the first month of testing, and unnecessary in the ED for acute presentations. </li>
