Insights

This study introduces a novel electromyographic (EMG) protocol to assess infant sucking-swallowing function. The protocol aids in diagnosing and understanding feeding difficulties and related neurological disturbances in newborns and infants.

Area of Science:

  • Neuroscience
  • Pediatrics
  • Biomedical Engineering

Context:

  • Sucking and swallowing are critical functions for infant nutrition and development.
  • Disturbances in these functions can lead to serious health issues like aspiration pneumopathies and feeding difficulties.
  • Existing diagnostic methods may not fully capture the complex pathophysiology of these disorders.

Purpose:

  • To develop and describe a comprehensive electromyographic (EMG) protocol for evaluating the sucking-swallowing function in newborns and infants.
  • To integrate traditional and novel EMG techniques for a detailed assessment.
  • To establish normative data for infants aged 0-3 years.

Summary:

  • The protocol combines traditional EMG (facial muscles, nerves, blink reflex) with original techniques (tongue, hypoglossal nerve, velum palatinum EMG).
  • A dynamic assessment using a baby bottle for liquid meals is included.
  • Normal procedural data and results for infants from birth to 3 years are provided, alongside observations in pathological conditions.

Impact:

  • This EMG protocol offers a valuable tool for assessing the sucking-swallowing reflex and identifying anatomo-functional disturbances in the brainstem.
  • It aids in understanding the pathophysiology of aspiration pneumopathies, feeding difficulties, and bucco-facial malformations.
  • The findings can inform clinical diagnosis and management strategies for affected infants.

Assessment of the Mouth01:26

Assessment of the Mouth

A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
Esophageal Achalasia01:27

Esophageal Achalasia

Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
