Streptococcal pharyngitis in general practice. 2. A note on dual infection and transient urinary abnormalities
Epidemiology and Infection
|October 1, 1992
Summary
Microscopic hematuria occurred more frequently after acute pharyngitis in patients with dual infections of group A streptococci and viruses. Further studies in children aged 5-9 are recommended to investigate this link.
Area of Science:
- Pediatric Nephrology
- Infectious Diseases
- Microbiology
Background:
- Acute pharyngitis can lead to complications like microscopic hematuria.
- The role of viral co-infections in post-streptococcal complications is not fully understood.
Purpose of the Study:
- To investigate the association between dual infections (group A streptococci and viruses) and microscopic hematuria following acute pharyngitis.
- To assess the feasibility and optimal population for prospective studies on viral etiology of transient hematuria and glomerulonephritis.
Main Methods:
- Retrospective analysis of patient data from 1965.
- Comparison of hematuria prevalence in patients with single versus dual infections.
Main Results:
- Microscopic hematuria was observed four times more often in patients with dual infections (group A streptococci and virus) compared to those with only streptococcal infection.
- The findings suggest a potential synergistic role of viral infections in the development of hematuria post-pharyngitis.
Conclusions:
- Dual infections with group A streptococci and viruses may increase the risk of microscopic hematuria after acute pharyngitis.
- Prospective studies in children aged 5-9 years are recommended for further investigation in general practice settings.

01:30Acute 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:

01:25Urinary Tract Infection II: Pathophysiology
The pathophysiology of urinary tract infections (UTIs) encompasses several progressive stages, beginning with bacterial colonization and culminating in potential systemic complications if untreated. UTIs are primarily initiated by bacteria, such as Escherichia coli, which often originate from the gastrointestinal tract and migrate to the urinary system through the periurethral area. This migration can occur via several routes, including improper hygiene practices, sexual activity, or...
01:30Urinary Tract Infection III: Diagnostic Studies and Interprofessional Care
A healthcare provider can diagnose a urinary tract infection (UTI) through several methods:Medical History and Symptoms: The provider will take a detailed medical history and ask about symptoms such as frequent urination, burning sensation during urination, and lower abdominal pain.Urinalysis: A clean-catch urine sample is collected in a sterile container and tested for the presence of bacteria, white blood cells (leukocytes), nitrites, blood, and protein. The presence of leukocytes and...
01:28Acute 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...
01:26Urine Studies II: Urine Culture and Sensitivity Test
A urine culture and sensitivity test is a diagnostic procedure used to identify urinary tract bacterial infections and determine the most effective antibiotics for treatment. This test is generally preferred when a patient shows manifestations of a urinary tract infection, such as frequent or painful urination, cloudy or foul-smelling urine, or lower abdominal pain.Purpose of the TestThe primary goals of a urine culture and sensitivity test are to:Determine the specific bacteria causing the...
01:27Streptococcal Pharyngitis
Streptococcal pharyngitis, commonly known as “strep throat,” is an acute infection of the oropharyngeal tissues caused by the Gram‑positive Group A Streptococcus (Streptococcus pyogenes). Transmission occurs primarily through respiratory droplets expelled during coughing, sneezing, or talking.Mechanisms of Host Entry and Immune EvasionUpon entering the host, S. pyogenes adheres to the mucosal epithelial cells of the pharynx via surface proteins, notably lipoteichoic acid and the antiphagocytic...
