Equilibrium and Balance01:15

Equilibrium and Balance

5.9K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

The Vestibular System01:29

The Vestibular System

42.9K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Pathophysiology of Vomiting01:22

Pathophysiology of Vomiting

2.3K
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...

Major Somatic Sensory Pathways01:28

Major Somatic Sensory Pathways

2.1K
Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the...

Dysrhythmias II: Classification of Tachyarrhythmias01:28

Dysrhythmias II: Classification of Tachyarrhythmias

361
Tachyarrhythmias are a type of dysrhythmia where the heart rate exceeds 100 beats per minute. Here are some common types of tachyarrhythmias:Sinus TachycardiaSinus tachycardia originates from increased impulses from the sinus node, leading to an elevated heart rate. It is often triggered by stress, fever, or exercise.Patients may experience palpitations, a sensation of a racing heart, dizziness, and chest discomfort.Causes and Risk Factors: Common causes include physical exertion, emotional...

Indirect Motor Pathways01:22

Indirect Motor Pathways

2.8K
The indirect motor or extrapyramidal pathways originate in the brainstem, the lower portion of the brain that connects it to the spinal cord. They consist of several distinct tracts, each with specialized functions. The four main tracts of the indirect motor pathways are the vestibulospinal tract, the reticulospinal tract, the tectospinal tract, and the rubrospinal tract.
The vestibulospinal tract originates in the vestibular nuclei of the brainstem. The vestibular system detects changes in...

Summary
This summary is machine-generated.

A new vertigo protocol effectively distinguishes central from peripheral acute vestibular syndrome in emergency settings. This approach aids diagnosis and avoids unnecessary imaging, with clinical-exploratory disagreement most frequently triggering its use.

Area of Science:

  • Emergency Medicine
  • Neurology
  • Otolaryngology

Background:

  • Vertigo diagnosis in emergency departments presents significant challenges.
  • A standardized vertigo protocol was developed to aid in distinguishing pathologies and guiding management.
  • Acute vestibular syndrome requires accurate and timely diagnosis to prevent adverse outcomes.

Purpose of the Study:

  • To evaluate the efficacy of a hospital-developed vertigo protocol.
  • To assess the protocol's utility in the diagnostic and therapeutic management of acute vestibular syndrome.
  • To determine if the protocol can differentiate central from peripheral vertigo origins.

Main Methods:

  • Retrospective descriptive observational study of 97 patients diagnosed with acute vestibular syndrome.
  • Utilized a specific vertigo protocol for patients in the emergency department.
  • Included the HINTS (Head Impulse, Nystagmus, Test of Skew) examination and a minimum 6-month follow-up.

Main Results:

  • The study included 97 patients with a mean age of 61.46 years.
  • Final diagnoses comprised 26.8% peripheral, 39.2% other-origin, and 34% central vertigo.
  • Stroke was identified in 18 patients within the central vertigo group; clinical-exploratory disagreement was the primary reason for protocol activation.

Conclusions:

  • The developed vertigo protocol is effective in differentiating central from peripheral acute vestibular syndrome.
  • The protocol helps avoid unnecessary imaging tests, improving diagnostic efficiency.
  • Clinical-exploratory disagreement, as noted by ENT specialists, was the most common trigger for protocol use.
