Acoustic Radiation Force Impulse (ARFI)-Imaging is a non-invasive ultrasound-based operator independent elastography method that assesses tissue stiffness. ARFI mechanically excites tissues with localized impulsive radiation resulting in shear wave propagation (m/s) away from the region of excitation. Shear wave velocity (SWV) increases when tissue is stiffer, and in muscle disorders, this may be related to either fibrosis or edema. Here we address the sensitivity and specificity of ARFI-imaging to changes in the individual muscles of patients with collagen 6 myopathy (COL6) and LAMA2 related muscular dystrophy (LAMA2), as...

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...

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.

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...

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...

Coding in Muscle Disease
This article provides an overview of administrative coding for patients with muscle disease and includes a case-based review of diagnostic and Evaluation and Management (E/M) coding principles in patients with myopathy. Procedural coding for electrodiagnostic studies and neuromuscular ultrasound is also reviewed.

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.

Acute Peripheral Neuropathy and Chikungunya Infection (P3.308)
Conclusions:CHIKV infection is possibly associated with neuropathic pain, with potential lesion to small-fiber nerves. Acute carpal syndrome might be caused by mechanical compression caused by soft tissue edema, by a direct infectious neuritis or by immune-mediated mechanisms. Further research on its pathogenesis and long-term prognosis is warranted.Disclosure: Dr. Dantas Pagliarini has nothing to disclose. Dr. Passos dos Santos has nothing to disclose.

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.

3-2-02. Texture Analysis of Muscle Ultrasound can differentiate myopathic conditions
Muscle sonography may show high densities in various myopathic conditions. Further classification among myopathic conditions could be possible by texture analysis, which analyzes relationships between the neighboring pixel densities.The following groups of subjects were assessed: (1) 19 patients with myotonic dystrophy type 1 (MD1), (2) 11 patients with inflammatory myopathy (IM), and (3) 16 normal control. A LOGIQe ultrasonography and an 11-MHz linear probe were used to obtain muscle images of medial gastrocnemius.

Quantitative muscle ultrasound in two canine models of human myopathies
Non-invasive tools to monitor the muscle over disease progression or during a treatment are in intensive development in clinical and preclinical research. Imaging as an alternative to more invasive and less representative muscle biopsies is particularly attractive. We tested the ability of muscle ultrasound to follow muscle pathology in the GRMD dog, a model of DMD, and the HACD1-deficient dog, a model of centronuclear myopathy (CNM). Ultrasound allowed a follow-up of muscle sectional area, with in both diseases a decrease in the biceps femoris (BF) muscle sectional area aggravating over time.

Orbital imaging in thyroid-related orbitopathy
Publication date: Available online 25 July 2018Source: Journal of American Association for Pediatric Ophthalmology and StrabismusAuthor(s): Christopher Lo, Shoaib Ugradar, Daniel RootmanSummaryOrbital imaging plays a central role in the diagnosis and management of thyroid-related orbitopathy (TRO). Diagnostically, it is used to compliment a careful ophthalmic examination, laboratory values, and ancillary studies to confirm the presence of TRO and/or dysthyroid optic neuropathy (DON). It can also be helpful in surgical planning and understanding the progression of thyroid myopathy. Computed tomography (CT), magnetic resonan...

Cardiovascular Health in Children and Adolescents With Congenital Adrenal Hyperplasia Due to 21-Hydroxilase Deficiency
Conclusions Increasing evidence indicates that CAH individuals are prone to develop a number of early CV risk factors, such as obesity, hypertension, insulin resistance, low-grade inflammation, increased IMT and subclinical cardiac dysfunction, already in childhood. The therapeutic management of patients with CAH remains a challenge and current treatment regimens do not always allow optimal biochemical control. Overexposure to glucocorticoids and mineralocorticoids as well as to androgens may contribute to the development of unfavorable metabolic and CV changes, even though metabolic derangement in CAH patients may also ...
