Disorders of the Autonomic Nervous System01:18

Disorders of the Autonomic Nervous System

1.4K
The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

300
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Physical Assessment of the Respiratory Tract II: Inspection

797
Physical assessment of the respiratory tract through inspection is a crucial step in understanding the patient's respiratory health. It provides insights into the functioning of the respiratory system, the musculoskeletal structure, and even the patient's nutritional status. This comprehensive approach involves observing several vital aspects: chest configuration, breathing patterns, respiratory rates, skin color, and use of accessory muscles.

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

Summary

Occupational Raynaud

Area of Science:

  • Occupational Medicine
  • Vascular Health
  • Epidemiology

Background:

  • Raynaud's phenomenon (RP) can be triggered by occupational exposures.
  • Understanding the prevalence of occupational RP is crucial for worker health.
  • Vibration and cold are suspected contributing factors.

Purpose of the Study:

  • To systematically review the prevalence of occupational Raynaud's phenomenon.
  • To identify key occupational risk factors associated with RP.
  • To synthesize existing evidence on vibration and thermal exposure in RP.

Main Methods:

  • A comprehensive literature search was conducted across major scientific databases (Medline, Embase, Web of Science, SciELO, Lilacs).
  • Eligibility criteria were applied to select relevant studies evaluating occupational RP prevalence.

  • Data extraction focused on vibration exposure, thermal factors, and reported prevalence rates.

    • Main Results:

    • 18 studies met the inclusion criteria from an initial search of 64 articles.
    • All included studies investigated upper limb exposure to vibrations.
    • Six studies addressed thermal exposure; no studies examined vinyl chloride exposure.

    Conclusions:

    • A higher prevalence of Raynaud's phenomenon was observed in workers using vibratory tools compared to unexposed individuals.
    • Increased vibration levels and prolonged exposure duration correlated with a higher incidence of RP.
    • Cold acts as a significant trigger and exacerbating factor for RP, contributing to hand-arm vibration syndrome vascular manifestations.
