Insights

Intensive care unit acquired weakness (ICUAW) in children, caused by critical illness polyneuropathy (CIP) or myopathy (CIM), is poorly understood. Further research is needed to determine its incidence, causes, and long-term effects in pediatric patients.

Area of Science:

  • Pediatric critical care medicine
  • Neuromuscular disorders

Background:

  • Intensive care unit acquired weakness (ICUAW) is common in critically ill patients, often due to critical illness polyneuropathy (CIP) or myopathy (CIM).
  • Improved survival rates and treatments like steroids and muscle relaxants contribute to ICUAW.
  • While CIP and CIM are reported in children, their prevalence and impact in this population are not well-established.

Purpose of the Study:

  • To review the current understanding of CIP and CIM pathophysiology, clinical presentation, diagnosis, and treatment.
  • To specifically focus on the pediatric age group regarding these conditions.

Main Methods:

  • Literature search using MedLine and Embase databases.
  • Inclusion of both adult and pediatric studies relevant to CIP and CIM.

Main Results:

  • ICUAW in children is an under-described condition.
  • Key aspects like incidence, etiology, and long-term prognosis remain largely unknown.

Conclusions:

  • Critical illness polyneuropathy and myopathy are infrequent but significant conditions in critically ill children.
  • These neuromuscular complications stem from multifactorial origins and impact patient morbidity, ICU stay duration, and potentially mortality.

Myasthenia Gravis ll: Pathophysiology

The disease process of myasthenia gravis begins at the neuromuscular junction, where antibodies attack key proteins needed for muscle activation. This immune reaction weakens signal transmission, leading to the characteristic muscle fatigue and weakness that define the condition.Immune-Mediated DamageIn most individuals, antibodies target acetylcholine receptors (AChRs) on the postsynaptic membrane of muscle cells. By blocking acetylcholine binding, these antibodies prevent the nerve signal...

Disorders of the Skeletal Muscle

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: Diagnostic Tests

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...

Myasthenia Gravis: Overview and Treatment

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...

Chemical Synapses01:26

Chemical Synapses

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...
