Abstract

Insights

A new JGG endoscope is safe and feasible for diagnosing acute bacterial rhinosinusitis in primary care. This tool may help general practitioners distinguish between bacterial and viral infections, reducing antibiotic overuse.

Area of Science:

  • Otolaryngology
  • Primary Care Medicine
  • Infectious Disease Diagnostics

Background:

  • Antibiotic overuse for acute rhinosinusitis in primary care is common due to diagnostic challenges.
  • Differentiating bacterial from viral infections is crucial for appropriate treatment and antibiotic stewardship.

Purpose of the Study:

  • To evaluate the on-site applicability and safety of the novel JGG endoscope for diagnosing acute bacterial rhinosinusitis in primary care settings.
  • To assess the potential of the JGG endoscope to aid general practitioners in clinical decision-making.

Main Methods:

  • A single-arm pilot study conducted in five Swiss primary care centers and one university ENT unit.
  • Adult patients with suspected acute bacterial rhinosinusitis were enrolled.
  • The JGG endoscope, attached to a pocket otoscope, was used for nasal cavity and middle meatus inspection and sample collection for bacterial culture after local anesthesia.

Main Results:

  • Middle meatus visualization was successful in 16 of 21 patients.
  • Sample collection from the middle meatus was successful in 10 patients.
  • Only one culture-confirmed bacterial rhinosinusitis case was identified; 11 viral infections were confirmed by PCR. No serious adverse events were reported during the 2-week follow-up.

Conclusions:

  • The JGG endoscope is feasible, safe, and well-accepted for use in daily primary care routines.
  • The device shows potential to assist general practitioners in differentiating bacterial from viral rhinosinusitis.
  • Improved diagnostics could lead to more targeted antibiotic prescribing and better patient outcomes.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Endoscopic Procedures I: Esophagogastroduodenoscopy

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Sputum Studies II: Culture and Sensitivity

Description
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
