Insights

Malignant otitis externa, often caused by Pseudomonas aeruginosa, is increasingly reported with other pathogens and antibiotic resistance. This review examines recent cases to update diagnostic criteria and management strategies for this rare infection.

Area of Science:

  • Infectious Diseases
  • Otolaryngology
  • Microbiology

Background:

  • Malignant otitis externa (MOE) is a severe infection of the external ear canal.
  • Recent reports indicate pathogens beyond Pseudomonas aeruginosa causing MOE.
  • Antibiotic resistance in Pseudomonas aeruginosa-related MOE is a growing concern.

Purpose of the Study:

  • To review recent cases of malignant otitis externa.
  • To identify non-Pseudomonas aeruginosa causative organisms.
  • To clarify current diagnostic criteria and management approaches.

Main Methods:

  • Literature review of reported malignant otitis externa cases.
  • Analysis of causative pathogens and their antibiotic susceptibility.
  • Assessment of diagnostic methods and treatment outcomes.

Main Results:

  • Identification of diverse bacterial pathogens in MOE cases.
  • Documentation of increasing antibiotic resistance patterns.
  • Variability in diagnostic approaches and treatment efficacy.

Conclusions:

  • Malignant otitis externa necessitates consideration of a broader range of pathogens.
  • Antibiotic stewardship is crucial due to emerging resistance.
  • Standardized diagnostic and management protocols are needed for optimal patient outcomes.

Acute Pyelonephritis II: Diagnostic Studies and Management

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...

Endotracheal Intubation II: Nursing Management

Endotracheal intubation is a critical procedure that can be lifesaving for many patients with respiratory distress or failure. The role of nursing in managing endotracheal tubes is pivotal, as it involves pre-intubation preparation, assisting during the procedure, and post-extubation care.
1. Nursing Care of Patients Before Intubation
Before the endotracheal intubation procedure, nurses play an essential role in ensuring the process goes smoothly. The nurses must be familiar with intubation...

Esophageal Perforation-II: Clinical Manifestations and Management

Esophageal perforations manifest in various clinical forms, influenced by factors such as the perforation's cause and location (cervical, intrathoracic, or intra-abdominal), the extent of contamination, and potential injury to adjacent mediastinal structures. The timing between the perforation occurrence and treatment initiation also affects the clinical presentation.
