Which of the following imaging studies is strongly indicated in all Pt's w/ juvenile idiopathic
arthritis?
A. MRI of affected bone
B. Slit lamp exam
C. Echocardiography
D. CT of long bones B. Slit lamp exam
Slit lamp microscopy to exclude eye involvement.
-Echocardiogram is performed w/ possible systemic JIC w/ fevers.
-MRI w/ gadolinium injection or CT scanning can be done if needed.
-Children on corticosteroids should have a dual-energy x-ray absorptiometry scan to document
osteopenia.
Herpetic gingivostomatitis -Symptoms of primary oral herpes (clusters of small vesicles
on the tongue, gums, and lips) are of sudden onset w/ fever, drooling, and refusal to eat.
-The lack of lesions on the hands and feet makes Coxsackievirus unlikely.

Diptheria rare b/c there is a vaccine. It presents w/ mandibular swelling and grey-white
patches in the mouth.
Bacterial vs Viral conjunctivitis The absence of itching indicates bacterial.

Glued or crusted eyelids, purulent discharge, absence of itching, and no previous Hx are all
consistent w/ bacterial conjuctivitis than other etiologies (viral, allergic)
itching 1st time: prob viral
Allergic and viral conjunctivitis are more commonly associated w/ itching and watery discharge.
Correction of severe hyponatremic dehydration (less than 130 mEq/L) or hypernatremic
dehydration (greater than 150 mEq/L) Corrected over 24 to 48 hours.
-rapid correction of hyperntremia may result in cerebral edema as a result of intracellular
swelling. This can cause herniation, permanent neurologic deficits, and myelinolysis.
