Hello, I am hoping someone can answer a question for me. Have you ever heard of a (sounds like) "Meyer's sign" or "Meyerson sign" with regard to the physical exam of a patient being evaluated for a glioblastoma? The physician specifically says the patient has a positive "Meyer's sign" but negative rooting and palmomental reflexes.

What I am specifically looking for is the spelling and a general definition of this. I can document a Meyer's loop or Meyer-Archambault loop but not a "sign." I have searched high and low and unfortunately do not have access to the physician for confirmation.

Thank you in advance for any and all help you can provide.
Loretta

Thanks for your question. Here's the definition of Mayer sign in the
"Dejong's The Neurologic Examination":

"The patient's hand is held in the examiner's hand, palm up, with the fingers
slightly bent and the thumb is slight flexion and abduction. The examiner
places slow but firm pressure on the proximal phalanges of the fingers,
especially the third and fourth fingers, flexing them at the metacarpophalangeal
joints and pressing them against the palm. In normal persons this is followed
by adduction and opposition of the thumb with flexion at the metacarpophalangeal
joint and extension at the interphalangeal joint. This response is absent in
corticospinal tract lesions, and its absence is known as the Mayer sign.
It is occasionally absent in normal individuals, but such absence should
be bilateral."

I hope this information is helpful. Best of luck.
