Pathophysiology of Vomiting01:22

Pathophysiology of Vomiting

3.3K
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...

Chemotherapy-Induced Nausea and Vomiting: Cannabinoids

802
Tetrahydrocannabinol (THC) is a phytocannabinoid that primarily interacts with the CB1 receptor, a type of G protein-coupled receptor (GPCR) predominantly in and around the chemoreceptor trigger zone (CTZ) and emetic center. THC also blocks the serotonin receptor activity in the dorsal vagal complex (DVC) by inhibiting serotonin release. THC exerts its anti-emetic effects through these interactions, which are beneficial for patients undergoing chemotherapy.
Two synthetic agonists of THC,...

Data Reporting and Recording

5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

Types of Reports II: Incident or Occurrence Report

1.3K
An Incident or Occurrence Report in a healthcare setting is a crucial document used to record any unexpected occurrence that may or may not have affected a patient, employee, or visitor. Such reports are critical to improving patient safety and include all details leading up to and including the event.
Purposes:
In the healthcare industry, reports play a crucial role in documenting incidents within an agency. The primary objective of these reports is to ensure patient safety, uphold the...

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists01:27

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists

715
5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...

Summary

Vomiting can cause lens dislocation, a rare condition leading to vision loss. This case highlights how increased intraocular pressure during vomiting can shock zonular fibers, dislocating the lens.

Area of Science:

  • Ophthalmology
  • Medical Case Reports

Background:

  • Lens dislocation is a prevalent ophthalmological condition causing vision impairment.
  • The association between vomiting and lens dislocation has not been previously documented.

Observation:

  • A 51-year-old male presented with acute vision decrease in the right eye, accompanied by dizziness and vomiting.
  • Ophthalmological examination diagnosed lens dislocation attributed to simple vomiting.

Findings:

  • Successful surgical intervention was performed for the lens dislocation.
  • The case provides insight into the pathogenesis of lens dislocation induced by vomiting.

Implications:

  • Simple vomiting can precipitate lens dislocation by increasing intraocular pressure.
  • This mechanism involves shocking the zonular fibers and displacing the lens into the anterior chamber.
