RE: Vocal cord abductor paralysis (VCAP) in Parkinson's dis ease

[Guest guest]

Pam -

I just saw a study at U of P. med school that collagen injections help vocal

cord atrophy in PD patients. The author of the study, Dr. Soo Kim, told me

that it has helped MSA patients too. I'm tryning to get more info.

Vocal cord abductor paralysis (VCAP) in Parkinson's disease: difference from

VCAP in multiple system atrophy.

Vocal cord abductor paralysis (VCAP) is rare in Parkinson's disease (PD),

while

it is frequent in multiple system atrophy (MSA). Although VCAP is a

life-threatening complication it has not yet been clarified whether there is

any

difference in the mechanism of VCAP between PD and MSA. Examining 3

autopsy-proven PD patients who developed severe VCAP requiring tracheostomy,

we

found the following differences in the mechanism of VCAP between MSA and PD:

(1)

clinical and laryngofiberscopic examination showed that VCAP in PD was not

exacerbated during sleep, unlike in MSA; (2) On histological examination of

the

intrinsic laryngeal muscles, the posterior cricoarytenoid muscle

demonstrated no

abnormalities in PD, while the muscle showed characteristic neurogenic

atrophy

in MSA. There seemed to be two types of VCAP, namely the nonparalytic type

observed in PD, and the paralytic type observed in MSA. Severe dysphagia

requiring tube-feeding was common among PD patients who presented with VCAP.

Although the relationship between VCAP and dysphagia is unknown, one should

be

aware of the possibility of fatal VCAP in PD patients with severe dysphagia.

There has been a lot written on the Parkinson's LISTSERV over the

years about using Collagen instead of Botox for vocal cord problems of

Parkinson's patients. Even Kaiser does it.
