Guest guest Posted May 13, 2002 Report Share Posted May 13, 2002 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. F. Vocal cord abductor paralysis (VCAP) in Parkinson's disease J Neurol Sci 1995 Jun;130(2):197-202 Vocal cord abductor paralysis (VCAP) in Parkinson's disease: difference from VCAP in multiple system atrophy. Isozaki E, Shimizu T, Takamoto K, Horiguchi S, Hayashida T, Oda M, Tanabe H. Department of Neurology, Tokyo Metropolitan Neurological Hospital, Japan. 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.

Guest guest Posted May 14, 2002 Report Share Posted May 14, 2002 : 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. Barbara Quote Link to comment Share on other sites More sharing options...
