title: [Treatment of multifocal motor neuropathies with conduction block in France in 2005. Results of a national opinion survey].
abstract: BACKGROUND
  The epidemiology of multifocal motor neuropathies (MMNs) is unknown. Prevalence is estimated at 1-2/100,000 population.
  
  
  METHODS
  The objective of this study was to gain knowledge on MMN diagnosis and treatment in metropolitan France. An opinion survey was conducted by SOFRES from November 2004 to March 2005 on 4,040 hospital and private practice physicians (215 interviewed directly and 3,825 contacted only by mail) using two questionnaires (one for hospital physicians [HPs] and the other for physicians working for the most part in private practice [PPPs]). SOFRES received 424 questionnaires, 392 of which were included in the study, 32 having been excluded for incomplete responses, giving a high response rate for this type of survey.
  
  
  RESULTS
  The 392 responses were made up of 296 for the HPs and 96 for the PPPs. The HPs were neurologists (56 percent), followed by internists (23 percent), and rheumatologists (13 percent), while the PPPs were nearly all neurologists (96 percent). One of the most interesting results was the number of patients seen during a physician's career: 1,964, comprising 1,557 for the HPs, and 407 for the PPPs. The responses describing care in terms of diagnosis and treatment generally complied with good practices as well as the recommendations and guidelines published in the field of MMN.
  
  
  CONCLUSIONS
  MMN is a rare disorder whose prevalence in France, estimated by this survey, comes close to that published in the literature; diagnosis and treatment seem globally satisfactory.
