Quantitative ultrasound reveals the impact of corticosteroids on skeletal muscle (S54.001)
Conclusions:Quantitative ultrasound measures GSL and QBA can determine the impact of prolonged corticosteroid therapy on muscle. Of the muscles tested, the tibialis anterior appears to show the greatest difference. This novel and unexpected finding may relate to the relatively high proportion of Type 2 muscle fibers in that muscle.Study Supported by:NIH K24 NS060951Disclosure: Dr. Martucci has nothing to disclose.

Semitendinosus myopathy and treatment with adipose-derived stem cells in working German shepherd police dogs.
Abstract Semitendinosus myopathy has been treated with numerous surgical and non-surgical therapies resulting in recurrence of lameness within 2 to 9 months. Eleven cases of semitendinosus myopathy diagnosed in 8 working police dogs that were treated with adipose-derived mesenchymal stem cells were retrospectively evaluated. At short-term follow-up < 6 mo, ultrasound and gait evaluations revealed a mean reduction in the overall intramuscular lesion size of 54.82% (SD +/- 18.02; range: 30.5% to 82.7%) and reduction in the Visual Assessment Score (VAS) of 1 to 3 points. At long-term follow-up > 1 y, in 8 cases...

Prenatal diagnosis of X ‐linked myopathy associated with a VMA21 gene mutation afforded through a novel targeted exome sequencing strategy applied in fetuses with abnormal ultrasound findings
We present the prenatal diagnosis of a rare X‐linked myopathy involving a new VMA21 gene mutation, detected through a novel prenatal exome sequencing‐based approach. Fetal malformations detected through routine prenatal ultrasound examination comprise a heterogeneous group potentially associated with genetic disorders where the underlying cause is difficult to establish. We present the prenatal diagnosis of a rare X‐linked myopathy involving a new VMA21 gene mutation, detected through a novel prenatal exome sequencing‐based approach.

Mutations in the NEB gene cause Fetal Akinesia/Arthrogryposis Multiplex Congenita
ConclusionsNemaline myopathy due to NEB mutation(s), leads to FADS/AMC. Currently, mutated NEB is under recognized as a cause for AMC/FADS. Our study attempts to raise recognition of this gene as a cause, suggesting the NEB gene should be included in genetic panels used for FADS/AMC cases and be fully covered when EXOME sequencing is utilized. Heterozygous mutation may suggest either compounding undetected one or di‐genic interaction that requires further genetic analyses.

MTM1-related myopathy carrier females manifest significant skeletal asymmetries and a spectrum of muscle involvement
X-linked myotubular myopathy (XLMTM) results from mutations in MTM1 and manifests in males with severe congenital hypotonia, weakness and respiratory insufficiency. Carrier females are less well-characterized, with reports indicating a spectrum of disease, ranging from mild facial weakness to severe congenital weakness. We deeply phenotyped a cohort of ten females with causative mutations in MTM1, evaluating the severity of disease expression based on muscle weakness, pulmonary function (spirometry and dynamic breathing MRI), muscle imaging (ultrasound and MRI) and skeletal morphology.

Skeletal muscle imaging in neuromuscular disease
Publication date: Available online 6 September 2016 Source:Journal of Clinical Neuroscience Author(s): Neil G. Simon, Yu-ichi Noto, Craig M. Zaidman Skeletal muscle imaging is increasingly used as a complement to clinical and electrophysiological examination in neuromuscular disease. Ultrasound and MRI have developed as the modalities of choice, each with strengths and limitations. Characteristic changes of muscle denervation and myopathy are seen on imaging which may delineate the nature of the disease process or help guide muscle biopsy. Identifying patterns of muscle involvement in hereditary myopathies may inform gene...

Prenatal features of Pena‐Shokeir sequence with atypical response to acoustic stimulation
ABSTRACT A fetal sonographic screening examination performed at 23 weeks showed polyhydramnios, micrognathia, fixed postures of all long bones, but no movement and no breathing. The fetus showed fetal heart rate acceleration but no movement when acoustic stimulation was applied with artificial larynx. All these findings persisted on serial examinations. The neonate was stillborn at 37 weeks and a final diagnosis of Pena‐Shokeir sequence was made. In addition to typical sonographic features of Pena‐Shokeir sequence, fetal heart rate accelerations with no movement in response to acoustic stimulation suggests that periphe...

Ultrasound in the Assessment of Myopathic Disorders
Summary: Neuromuscular ultrasound (US) augments a careful physical examination and electrodiagnostic evaluation in the evaluation of suspected myopathy. Ultrasound evaluation of muscle can identify abnormal echo intensity, size, and movement. Because it is painless and noninvasive, US can be used to evaluate multiple muscles to direct the electrodiagnostic examination or muscle biopsy. Some patterns of muscle involvement can suggest specific etiologies. Most muscular dystrophies show homogenously increased muscle echo intensity with attenuation of the US signal, likely resultant from increased intramuscular fat and fibrosi...

Novel myopathy in a newborn with Shwachman–Diamond syndrome and review of neonatal presentation
We report a newborn boy with asphyxia, narrow thorax, and severe hypotonia initially suggesting a neuromuscular disease. The muscle biopsy showed myopathic changes with prominent variability in muscle fiber size and abnormal expression of developmental isoforms of myosin. The myofibrils showed focal loss and disorganization of myofilaments, and thickening of the Z‐discs including some abortive nemaline rods. The boy became permanently dependent on assisted ventilation. Pancreatic insufficiency was subsequently diagnosed, explaining the malabsorption and failure to thrive. Except transitory thrombocytopenia and leukopenia...

Fasciitis frequently accompanies myopathy in acute critical illness muscle wasting: Evidence from qualitative ultrasound and muscle biopsy analysis
A rapid and early loss of skeletal muscle mass underlies the physical disability that is common amongst survivors of critical illness (CI). The functional capacity of skeletal muscle depends on its quantity as well as quality, which may be adversely affected. Our main objectives were to characterise changes in muscle echogenicity, pennation angle and fascial characteristics that occur early in CI, and to relate these to histologically defined myofibre necrosis and fascial pathology. Subjects comprised a subgroup of patients recruited to the Musculoskeletal Ultrasound in CI: Longitudinal Evaluation (MUSCLE) study.

What's in the Literature?
Abstract: In this issue, we review new information related to amyotrophic lateral sclerosis, diagnostic testing practices, differences in clinical management between patients seen in multidisciplinary and regular clinics, and managing end-of-life care issues. There is new information on genes and genetic risk factors and environmental risk factors. There are 2 other forms of motor neuron disease, progressive muscular atrophy, and spinal muscular atrophy that are also considered. Inflammatory neuropathies are important to identify as they can be treated. Ultrasound is being applied to the diagnosis of chronic inflammatory d...

Efficacy of ultrasound elastography in detecting active myositis in children: can it replace MRI?
Conclusion Compression–strain US elastography does not accurately detect active myositis in children with juvenile idiopathic inflammatory myopathy and cannot replace MRI as the imaging standard for detecting myositis in these children. The association between abnormal US elastography and increased muscle echogenicity suggests that elastography is capable of detecting muscle derangement in patients with myositis; however further studies are required to determine the clinical significance of these findings.
