International Myotonic Dystrophy Consortium (September 2009)
- Spectrum of disease manifestations of juvenile myotonic dystrophy type 1 (JDM) patients
The full spectrum of the clinical manifestations of juvenile myotonic dystrophy (JDM), or childhood-onset myotonic dystrophy, is not entirely understood. Little information is available on the symptoms, progression of the disease over time, and other characteristics of JDM and how these characteristics compare or contrast with patients having congenital (from birth) and adult-onset forms of DM1. We investigated the impact of disease in congenital DM (CDM) and JDM by analyzing patient reported data and reviewing patient medical records of members of the National Registry (more...).
- Diagnostic odyssey of myotonic dystrophy type 2 (DM2) patients
Delays in receiving an accurate diagnosis can have a significant impact on the burden of disease for patients, on family planning, and on the management of their symptoms. Colleagues from Finland have hypothesized that many DM2 patients are misdiagnosed because symptoms of DM2 often overlap with those of other more common disorders. We investigated diagnostic delay in myotonic dystrophy type 1 (DM1) and DM2 patients enrolled in the National Registry by analyzing patient-reported data and reviewing patient medical records (more...).
International Myotonic Dystrophy Consortium (September 2007)
- Gastrointestinal (GI) symptoms in myotonic dystrophy type 1 (DM1) patients enrolled in the NIH Registry
Gastrointestinal (GI) problems are a frequent and serious complaint in DM1 patients. The cause of GI disturbances in DM1 remains unclear and limited information is available about the overall prevalence of symptoms and most frequently used treatments. We reviewed the information provided by members of the Registry in order to examine the prevalence of GI symptoms and the types of medications that are used. We also investigated if other characteristics (age of symptom onset, weight, CTG repeat size) were linked to experiencing GI symptoms (more…).
American Academy of Neurology Meeting (April 2007)
- Neoplasms in myotonic dystrophy type 1
Myotonic dystrophy type 1 (DM1) is the most common adult muscular dystrophy and causes progressive muscle weakness, myotonia and multi-system complications. DM1 is the result of a specific genetic mutation referred to as a DNA expansion or an increase in the amount of DNA that is normally located on a chromosome. The mutation causes the cells in muscle and other tissue to function incorrectly. The extent to which this mutation affects the body is not entirely understood. For example, there is limited information on how the genetics of DM1 may potentially influence various types of benign (non-cancerous) and malignant (cancerous) tumors (more…).
- Clinical description of infantile facioscapulohumeral muscular dystrophy (FSHD)
Approximately 5% of individuals diagnosed with FSHD have a more severe sub-type of the disease which begins in early childhood, referred to as infantile/childhood FSHD. The diagnosis of infantile FSHD is based upon two symptoms; facial weakness before the age of five and shoulder weakness before the age of ten. Additionally, many of those diagnosed with infantile FSHD report symptoms of hearing loss and problems with retinal tissue. There is very little information available on the symptoms and other characteristics of infantile FSHD (more…).
American Academy of Neurology meeting (April 2006)
- Prominent signs of disease progression: Data from the National Institutes of Health’s (NIH) Registry of Myotonic Dystrophy (DM) and Facioscapulohumeral Muscular Dystrophy (FSHD) Patients and Family Members
The American Academy of Neurology meeting, is described as, “one of the world's largest gatherings of neurology professionals, bringing together more than 10,000 neurologists and neuroscientists.” Our poster described the short term progression of DM and FSHD symptoms using information that was gathered from Registry members annual update forms. The presentation also sought to encourage researchers to take advantage of the valuable resource that the Registry provides. A section of our presentation was included in a program that highlighted the most interesting and relevant research being presented in the area of neuromuscular diseases.
International Myotonic Dystrophy Consortium (October 2005)
- Presented information collected from all members of the Registry about the burdens of DM and offered improvements for measuring patient reported symptoms at a research conference sponsored by the International Myotonic Dystrophy Consortium. Researchers and patients from all around the world attended this conference in Quebec City, in October, 2005 to learn about new advances and research in Myotonic Dystrophy.
Burden of Muscle Disease Workshop (January 2005)
- The Burden of Muscle Disease Workshop sponsored by the National Institutes of Health (NIH) invited top researchers in several fields including medical economics, physical therapy, psychology, muscular dystrophy, and cell biology to attend this conference. The Registry presentation illustrated that the burdens of DM and FSHD extend beyond physical symptoms, by affecting areas such as employment, mood and sleep. The additional support that patients often need, including medication, canes, wheelchairs and therapies was also discussed.
