Local Anesthetics: Differential Sensitivity of Nerve Fibers

1.7K
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

Peripheral Nervous System: Ganglia and Nerves

7.3K
The Peripheral Nervous System (PNS) is a crucial component of the body's neural network, extending beyond the central nervous system (CNS) to bridge the gap between the CNS and the external environment. It encompasses nerves, ganglia, and sensory receptors.
Nerves
The nerve is a bundle of axons that serves as the communication highway in the PNS. Each nerve is ensheathed in a protective layer of connective tissue called the epineurium. This outermost layer safeguards the nerve and supports the...

Summary
This summary is machine-generated.

Leprosy neuropathy involves immune responses causing chronic or acute nerve damage. Comprehensive evaluation, including nerve conduction studies and ultrasonography, aids in assessing nerve function and guiding treatment.

Area of Science:

  • Neurology
  • Immunology
  • Infectious Diseases

Background:

  • Leprosy neuropathy is characterized by focal or multifocal, asymmetric nerve involvement.
  • It evolves chronically, with acute exacerbations during type 1 or type 2 reactions.
  • Nerve enlargement causing entrapment syndromes and pain (inflammatory or neuropathic) are common.

Purpose of the Study:

  • To outline a comprehensive approach for evaluating leprosy neuropathy.
  • To highlight the role of electrophysiological and imaging techniques in assessment.
  • To propose a novel composite nerve clinical score for longitudinal evaluation.

Main Methods:

  • Detailed clinical evaluation including nerve palpation, pain assessment, sensory mapping, muscle testing, and autonomic function tests.
  • Nerve conduction studies (NCS) to detect nerve dysfunction and new lesions.
  • Nerve ultrasonography as a promising imaging modality.
  • Development of a composite nerve clinical score.

Main Results:

  • Leprosy neuropathy is immune-mediated and can present acutely or chronically with exacerbations.
  • Nerve conduction studies are sensitive for detecting dysfunction and entrapment syndromes.
  • Nerve ultrasonography shows promise for evaluating nerve changes in leprosy.
  • A composite nerve clinical score is proposed for longitudinal assessment.

Conclusions:

  • A thorough, multi-modal evaluation is essential for managing leprosy neuropathy.
  • Nerve conduction studies and ultrasonography are valuable tools for diagnosis and monitoring.
  • The proposed composite nerve clinical score may improve longitudinal nerve function assessment in leprosy patients.
