Progressive Muscular Atrophy
Progressive Spinal Muscular Atrophy
Internal medicine; a work for the practicing physician on diagnosis and treatment, with a complete Desk index (1920) (14598402017)
Presentation
- The overall clinical presentation was consistent with motor neurone disease. Cerebrospinal fluid analysis revealed mild pleocytosis and increased protein concentration.[ncbi.nlm.nih.gov]
- A patient presenting with PMA with rapid clinical evolution likely has the pathology and pathophysiology of ALS whether or not upper motor neuron signs evolve.[ncbi.nlm.nih.gov]
- Seven other patients presenting with a PMA syndrome developed upper motor neuron signs during a one-year period of observation and were excluded from the study. The rate of progression was variable.[ncbi.nlm.nih.gov]
- We present the electrophysiologic data at baseline of 37 patients who were included in our prospective study on sporadic adult-onset progressive muscular atrophy (PMA).[ncbi.nlm.nih.gov]
- High titers of anti-GM1 IgM antibodies were present in 43 % of MMN patients and 7 % of PMA patients.[ncbi.nlm.nih.gov]

- In particular, there was no serological evidence to suggest an association between persistent infection with any poliovirus type and amyotrophic lateral sclerosis or late-onset postpoliomyelitis progressive muscular atrophy.[ncbi.nlm.nih.gov]
- The role of centromeric SMN copy (SMN2) has been postulated in progressive muscular atrophy (PMA). The aim of this study was to analyse the SMN1 and SMN2 copy number variations in patients with PMA.[ncbi.nlm.nih.gov]
- OBJECTIVE: To investigate the natural history and prognostic factors in patients with nonhereditary, adult-onset progressive muscular atrophy. DESIGN: Inception cohort conducted for 18 months.[ncbi.nlm.nih.gov]

Treatment
- Offers practical, clinically relevant material for the diagnosis and treatment of musculoskeletal conditions.[books.google.com]
- Review decision on the use of Riluzole for the treatment of motor neurone disease.[gpnotebook.co.uk]
- The patient improved clinically and symptom progression ceased after initiation of treatment. There was complete resolution of the abnormal brain MRI lesions; however, the cervical spinal cord MRI lesion and muscular atrophy remained unchanged.[ncbi.nlm.nih.gov]
- Presence of monoclonal gammopathy may indicate specific pathogenic pathways and may facilitate the development of novel treatment strategies.[ncbi.nlm.nih.gov]
- After the diagnosis is made the doctor will discus treatment options with the patient. The actual treatment that is effective in stopping the deterioration of the nerve is still unknown.[ic.steadyhealth.com]
Prognosis
- The distinction is important because PMA is associated with a better prognosis than classic ALS.[en.wikipedia.org]
- Axial onset, however, predicts the early onset of respiratory failure, and a poor prognosis.[ncbi.nlm.nih.gov]
- Patients with a low VC at baseline and a sharp decline of VC during the first 6 months have an especially poor prognosis.[ncbi.nlm.nih.gov]
- The prognosis for this disorder is almost never good as the patient does not live form more than a several years after he or she is diagnosed with it.[ic.steadyhealth.com]
- Prognosis .—This is unfavorable as to cure, though in rare cases the progress of the atrophy is arrested. Treatment .—Medication has but little effect upon the progress of the disease.[henriettes-herb.com]
Etiology
- The weight of available evidence concerning its etiology, most recently reviewed by England and Denny-Brown, 1 is in favor of an affection of the spinal cord and of peripheral nerves being the primary process, the muscular changes being secondary; but[jamanetwork.com]
- In addition, the patient developed progressive muscular atrophy of unknown etiology at the beginning of the third decade, and is bedridden at the present time.[jlc.jst.go.jp]
Epidemiology
- 3] [4] Epidemiological data refers to the US, unless otherwise specified.[amboss.com]
- SMA with respiratory distress (SMARD1) Inheritance is autosomal recessive due to mutations in the IGHMBP2 gene on chromosome 11q13. [ 9 ] Epidemiology The estimated incidence is between 1 in 6,000 and 1 in 10,000 live births and the carrier frequency[patient.info]

Pathophysiology
- A patient presenting with PMA with rapid clinical evolution likely has the pathology and pathophysiology of ALS whether or not upper motor neuron signs evolve.[ncbi.nlm.nih.gov]
- To further investigate the pathophysiology of MMN and PMA we determined concentrations of 16 mainly B-cell associated inflammatory markers in serum from 25 patients with MMN, 55 patients with PMA, 25 patients with amyotrophic lateral sclerosis (ALS) and[ncbi.nlm.nih.gov]
