Treatment involves antifungal medications. 
tinea capitis

worm) of the scalp. This disorder occurs most com-
monly in children, especially those in late childhood

ated with bald spots. Treatment involves antifungal
medications.
tinea corporis

ringworm) of the skin with characteristic spots that

Tinel’s sign
The sign that a nerve is irritated.
Tinel’s sign is positive when lightly banging (per-
cussing) over the nerve elicits a sensation of tin-
gling, or “pins and needles,” in the distribution of
the nerve. For example, in carpal tunnel syndrome,
where the median nerve is compressed at the wrist,
the test for Tinel’s sign is often positive, eliciting tin-
gling in the thumb, index, and middle fingers.
tinnitus
Ringing in the ears. Tinnitus has many
causes, including some medications (including
aspirin and other anti-inflammatory drugs), dis-
eases such as Ménière’s disease, aging, and ear
trauma.
