Abstract

Insights

Pantoea dispersa can cause acute rhinosinusitis, leading to shorter antibiotic treatment and fewer surgeries. This study identifies P. dispersa as a potential sinonasal colonizer causing rhinosinusitis.

Area of Science:

  • Microbiology
  • Otolaryngology
  • Infectious Diseases

Background:

  • Pantoea dispersa's role in rhinosinusitis is largely unexplored.
  • P. dispersa has not been previously identified as a commensal bacterium in the sinonasal cavity.

Purpose of the Study:

  • To investigate the role of Pantoea dispersa in the development of rhinosinusitis.
  • To determine the clinical characteristics and outcomes of P. dispersa-associated rhinosinusitis.

Main Methods:

  • Retrospective review of 274 rhinosinusitis patients diagnosed at a Taiwanese medical center.
  • Sinus cultures were analyzed between July 2017 and July 2019.
  • Clinical data, including symptoms and treatment outcomes, were compared between patients with and without P. dispersa.

Main Results:

  • Twenty-three patients presented with acute P. dispersa rhinosinusitis, characterized by purulent rhinorrhea.
  • P. dispersa patients received shorter antibiotic treatment (19.9 days vs. 28.9 days) and had a lower surgery rate (0% vs. 16.7%).
  • Olfactory dysfunction was associated with a higher likelihood of surgical treatment in rhinosinusitis patients.

Conclusions:

  • Pantoea dispersa can colonize the sinonasal cavity and cause acute rhinosinusitis.
  • P. dispersa-associated rhinosinusitis appears to require less surgical intervention and shorter treatment durations.
  • Olfactory dysfunction may indicate a more complex or chronic rhinosinusitis course necessitating surgical consideration.

Pneumonia I: Introduction01:30

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Epistaxis01:30

Epistaxis

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Anatomy of Respiratory System I: Upper Respiratory Tract01:29

Anatomy of Respiratory System I: Upper Respiratory Tract

The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.
Nose and nasal cavity
The nose and nasal cavity represent the main external openings of the respiratory tract....

Pneumonia IV: Management

The treatment of pneumonia varies based on its severity and the causative pathogen. Here is a structured approach to managing pneumonia, integrating pharmaceutical and supportive care strategies.
Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:

Suctioning the Nasopharyngeal Airway01:29

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.
