MYOTONIA ATROPHICA (DYSTROPHIA MYOTONICA)

Respiration in Dystrophia Myotonica.

The interesting paper by Dr J E Clague et al (March 1994;49:240-4) contains some results and conclusions which are at variance with earlier studies. Firstly, their results showed that the vent-ilatory response to carbon dioxide in these patients was lower than in the controls, but the difference was not significant. Several earlier studies showed clear evidence of a reduction in the slope of th...

Immunoglobulin levels in dystrophia myotonica.

Levels of immunoglobulins IgG, IgA, and IgM were measured in 38 patients with myotonic dystrophy, in normal members of their families, and in matched controls. Log IgG was significantly reduced in the patients. IgG investigation provides a further parameter to appraise the status of apparently unaffected members of myotonic dystrophy families.

Dystrophia myotonica: a multisystem disease.

AN AI~A~S'rHESIOLOCIST is aware of the need for caution when confronted with a patient suffering from a myotonic syndrome. On reviewing the literature, 1,2 it becomes evident that the stress has been on the myotonic aspects of the disease. However, dystrophia myotonica is a multisystem disease, and the following case report and related discussion illustrate the many facets which need considerat...
