What is a Sensory System?01:31

What is a Sensory System?

100.8K
Sensory systems detect stimuli—such as light and sound waves—and transduce them into neural signals that can be interpreted by the nervous system. In addition to external stimuli detected by the senses, some sensory systems detect internal stimuli—such as the proprioceptors in muscles and tendons that send feedback about limb position.

Rat Burn Model to Study Full-Thickness Cutaneous Thermal Burn and Infection

6.0K
A model mimicking the clinical scenario of burn injury and infection is necessary for furthering burn research. The present protocol demonstrates a simple and reproducible rat burn infection model comparable to that in humans. This facilitates the study of burn and infections following burn for developing new topical antibiotic treatments.

A complete sensory examination consists of testing primary sensory modalities as well as cortical sensory function. Primary sensory modalities include pain, temperature, light touch, vibration, and joint position sense. Sensation of the face is discussed in the videos Cranial Nerves Exam I and II, as are the special senses of smell, vision, taste,...

A Quantitative Sensory Testing Paradigm to Obtain Measures of Pain Processing in Patients Undergoing Breast Cancer Surgery

9.8K
Persistent postsurgical pain may be related to changes in pain processing. By assessing pain in response to standardized stimuli, changes in pain processing can be elucidated. We present methods to obtain pain thresholds to different stimuli and a measure of endogenous analgesia in patients undergoing breast cancer...

Burn Injuries01:22

Burn Injuries

4.2K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...

Summary

Burn patients experience sensory dysfunction in burned skin areas, showing reduced sensitivity to heat, cold, and touch. Quantitative Sensory Testing (QST) can assess this nerve damage and aid recovery.

Area of Science:

  • Neurology
  • Dermatology
  • Regenerative Medicine

Background:

  • Burn injuries impair peripheral nervous system regeneration, affecting somatosensitive skin receptors.
  • The precise patterns of sensory recovery after burns remain unclear.
  • Understanding sensory dysfunction is crucial for managing burn patient recovery.

Purpose of the Study:

  • To investigate sensory dysfunction patterns in severe burn patients.
  • To evaluate sensitivity to heat, cold, pain, and touch post-burn.
  • To assess the utility of Quantitative Sensory Testing (QST) in burn patients.

Main Methods:

  • An observational retrospective study involving 26 severe burn patients.
  • Utilized Quantitative Sensory Testing (QST) for termoalgesic measurements.
  • Employed electrical sympathetic skin response (SSR) and Von Frey filaments for touch/pressure assessment.

Main Results:

  • Patients exhibited hypoesthesia (reduced sensitivity) to heat, cold, and touch in burned areas compared to healthy skin.
  • No significant hypoesthesia was observed for heat-pain sensation.
  • Sensory dysfunction patterns varied based on burn severity and type.

Conclusions:

  • Burn patients demonstrate significant sensory dysfunction in post-burn skin.
  • QST is a valuable tool for quantifying sensory deficits in burn survivors.
  • Further high-quality research is needed to fully elucidate sensory regeneration patterns.
