Equilibrium and Balance01:15

Equilibrium and Balance

4.8K
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...

Pathophysiology of Vomiting01:22

Pathophysiology of Vomiting

689
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...

The Vestibular System01:29

The Vestibular System

39.8K
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.

Dysrhythmias II: Classification of Tachyarrhythmias

13
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...

COPD: Pathogenesis and Clinical Features01:20

COPD: Pathogenesis and Clinical Features

376
Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...

Social Anxiety Disorder01:28

Social Anxiety Disorder

67
Social anxiety disorder, also known as social phobia, is characterized by an intense fear of social situations where one might face humiliation, rejection, embarrassment, or negative evaluation. This disorder leads individuals to avoid activities like casual conversations, public speaking, or seemingly simple tasks such as eating, signing documents, or swimming, in public settings. Its impact extends beyond discomfort, often significantly interfering with daily functioning and quality of life.

Summary

COVID-19 can cause neuro-otological issues like vertigo. This study found vestibular neuritis and benign paroxysmal positional vertigo in post-COVID-19 patients and close contacts, indicating peripheral vestibular dysfunction.

Area of Science:

  • Neurology
  • Otolaryngology
  • Infectious Diseases

Background:

  • COVID-19 is suspected to have significant neuro-otological effects, including vertigo, which are often underdiagnosed.
  • This research investigates the prevalence and causes of vertigo in individuals with a history of COVID-19 infection and their close contacts.

Purpose of the Study:

  • To determine the occurrence of vertigo as a presenting symptom or sequela in COVID-19 patients and close contacts.
  • To analyze the etiological characteristics of vertigo in these populations.

Main Methods:

  • A cross-sectional study involving convenient sampling.
  • Participants included post-COVID-19 patients and close contacts presenting with vertigo.
  • Evaluations comprised neurological and otological examinations, PCR testing for COVID-19, and videonystagmography (VNG).

Main Results:

  • The study included 44 participants: 7 post-COVID-19 patients and 37 close contacts.
  • Among post-COVID-19 patients, 85.7% were diagnosed with vestibular neuritis (VN) and 14.3% with benign paroxysmal positional vertigo (BPPV).
  • In close contacts, 23% tested positive for COVID-19; of these, 66.7% had VN and 33.3% had BPPV.

Conclusions:

  • Vertigo can manifest as a complication or presenting symptom in COVID-19 patients.
  • The findings suggest peripheral vestibular dysfunction as the primary cause of vertigo in this context.
