Abstract

Insights

This study identified the most common bacteria causing acute otitis media (AOM) in children. Streptococcus pneumoniae and Haemophilus influenzae were the most prevalent pathogens, informing antibiotic treatment strategies for AOM.

Area of Science:

  • Pediatric Infectious Diseases
  • Microbiology
  • Otolaryngology

Context:

  • Acute otitis media (AOM) is a frequent childhood illness and a leading reason for pediatric antibiotic prescriptions.
  • Tympanocentesis is the standard for identifying AOM pathogens but requires middle ear exudate.

Purpose:

  • To determine the prevalence of microorganisms responsible for AOM in pediatric patients at a public hospital.

Summary:

  • A study of 324 children with AOM found Streptococcus pneumoniae (39.5%) and Haemophilus influenzae (37.4%) as the most common pathogens.
  • Nearly 40% of children had received prior antibiotic treatment, with some receiving ineffective antibiotic regimens.
  • Middle ear fluid cultures identified bacterial growth in 59.1% of children who had received antibiotics.

Impact:

  • Findings aid in optimizing antibiotic selection for AOM, potentially reducing treatment failures and antimicrobial resistance.
  • Highlights the need for accurate pathogen identification in pediatric AOM management.
  • Provides epidemiological data on AOM-causing organisms in a specific pediatric population.

Acute Pharyngitis01:30

Acute Pharyngitis

Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Microbiota of the Respiratory Tract01:29

Microbiota of the Respiratory Tract

The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more like...
Pneumonia I: Introduction01:29

Pneumonia I: Introduction

Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
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...

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...
Tonsillitis I: Introduction01:30

Tonsillitis I: Introduction

Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.
Etiology
Three primary contributing factors have been identified.
