Myasthenia Gravis: Overview and Treatment01:20

Myasthenia Gravis: Overview and Treatment

2.5K
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

1.7K
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...

Disorders of the Skeletal Muscle

1.5K
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...

Chemical Synapses01:26

Chemical Synapses

10.9K
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...

Autoimmune Disorders01:29

Autoimmune Disorders

1.3K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Area of Science:

  • Neurology
  • Pediatric Neurology
  • Autoimmune Disorders

Background:

  • Autoimmune myasthenia gravis is a rare neuromuscular junction disorder.
  • Early diagnosis and treatment are crucial for managing pediatric cases.

Observation:

  • An 11-year-old girl presented with diplopia, divergent squint, fluctuating ptosis, nasal voice, and dysphagia.
  • These symptoms suggested an autoimmune etiology affecting neuromuscular transmission.

Findings:

  • Electromyography confirmed autoimmune myasthenia gravis.
  • Treatment with corticosteroids, plasmapheresis, and pyridostigmine effectively controlled symptoms.
  • Subsequent left thoracoscopic thymectomy aimed for disease remission.

Implications:

  • This case highlights the importance of recognizing early signs of myasthenia gravis in children.
  • Prompt and multimodal treatment strategies can lead to favorable outcomes.
  • Surgical intervention like thymectomy may be a viable option for achieving long-term remission in pediatric myasthenia gravis.
