Disorders of the Skeletal Muscle01:28

Disorders of the Skeletal Muscle

1.6K
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

Myasthenia Gravis: Overview and Treatment

2.6K
Myasthenia gravis is a neuromuscular transmission disorder characterized by weakness and increased fatigability of skeletal muscles. It is an autoimmune disease affecting approximately one in 2000 people, where antibodies against the α1 subunit of nicotinic acetylcholine receptors are produced.
These antibodies interfere with the function of the nicotinic receptors in three ways: by binding to the receptor and disrupting acetylcholine binding; by causing cross-linking of receptors which...

Myasthenia Gravis: Diagnostic Tests

1.8K
Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
The edrophonium test is a diagnostic tool for myasthenia gravis. It involves...

Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...

Chemical Synapses01:26

Chemical Synapses

11.0K
Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

Area of Science:

  • Neurology
  • Intensive Care Medicine
  • Muscle Physiology

Background:

  • Critical illness myopathy (CIM) is a primary myopathy linked to poor outcomes in critically ill patients.
  • The precise causes and mechanisms of CIM remain incompletely understood.
  • While muscle biopsy confirms CIM, electrophysiological tests are vital for probable diagnosis and differential diagnosis.

Purpose of the Study:

  • To review conventional electrophysiological tests for diagnosing critical illness myopathy.
  • To discuss the application of novel electrophysiological methods in CIM diagnosis.
  • To summarize current knowledge on electrophysiological approaches to CIM.

Main Methods:

  • Review of literature on electrophysiological tests in critical illness myopathy.
  • Summary of nerve conduction studies, needle electromyography, direct muscle stimulation, and repetitive nerve stimulation.
  • Inclusion of studies utilizing muscle velocity recovery cycles.

Main Results:

  • Electrophysiological tests are essential for diagnosing probable CIM and differentiating it from other neuromuscular disorders.
  • Conventional methods like NCS, EMG, DMS, and RS are summarized.
  • Emerging techniques, such as muscle velocity recovery cycles, offer new diagnostic avenues.

Conclusions:

  • Electrophysiological testing plays a critical role in the diagnosis and management of critical illness myopathy.
  • Further research into novel electrophysiological techniques may enhance diagnostic accuracy and mechanistic understanding of CIM.
