Provigil Survey Finds Strong Support From Myotonic Dystrophy Patients

For quite a few years, I have been strongly advocating the use of Provigil the brand name for modafinil for helping with sleep related issues n Myotonic Dystrophy. Many patients with myotonic dystrophy have tremendous issues with excessive sleep and sleep disruptions.  A study from France in 2009 concluded that a controlled study showed “no significant effects on daytime sleepiness” This study puzzled me as many patients reported very good results from this drug.

A survey conducted by the Myotonic Dystrophy Support Group,  MDSG in England has concluded that over 80% of survey respondents found that the drug had a marked benefit or a dramatic benefit. This concurs with the informal feedback that I have had here in the USA. This also focuses attention on patient centered approaches versus medical centered approaches. Patient centered approaches are very important to give direct patient feedback rather than just visibility to medical professionals opinions based on limited patient facts.

A Case of Myotonic Dystrophy Complicated with
Raynaud’s Phenomenon

S. Fujimaki, A. Kurihara, K. Tamura and Z. Shiozawa

We reported a case of myotonic dystrophy complicated with Raynaud’s phenomenon. The patient was a 66-year-old male, who was admitted to our hospital with complaints of muscle atrophy, general fatigue and coldness of the hands. He noted muscle power loss about 20-years ago and later developed felt urinary incontinence, constipation, dysphagia, hoarseness and muscle atrophy. The diagnosis of myotonic dystrophy was confirmed by EMG and the biopsy of M.biceps brachii. By the cold stress test and blood analysis, he was diagnosed as Raynaud’s disease. The findings indicate that Raynaud’s phenomenon is included in the clinical feature of myotonic dystrophy. This phenomenon was the rare manifestation of smooth muscle involvement by myotonic dystrophy.
