Summary
Corynebacterium species can cause severe chronic urinary tract infections, known as encrusted cystitis (EC). Early diagnosis and treatment in pediatric patients, though rare, are crucial for a positive outcome.
Area of Science:
- Urology
- Infectious Diseases
- Microbiology
Background:
- Corynebacterium species are often misidentified as contaminants in urine cultures.
- Encrusted cystitis (EC), a severe chronic urinary tract infection, can lead to significant morbidity and mortality.
- EC is predominantly observed in elderly and immunocompromised individuals, with pediatric cases being exceedingly rare.
Observation:
- A female adolescent on high-dose corticosteroids presented with persistent dysuria following urinary catheterization.
- Bladder ultrasound revealed abnormalities, and cystoscopy showed characteristic signs consistent with EC.
- The patient's symptoms began 4 months prior to diagnosis and treatment initiation.
Findings:
- Diagnosis of encrusted cystitis (EC) was confirmed in a pediatric patient.
- The patient, an adolescent on high-dose steroids, experienced persistent dysuria post-catheterization.
- Prompt treatment led to an excellent clinical response, indicating the efficacy of intervention.
Implications:
- This case highlights the importance of considering Corynebacterium species and EC in the differential diagnosis of persistent urinary symptoms in pediatric patients, even in rare instances.
- Early recognition and appropriate management of EC in adolescents can lead to favorable outcomes.
- Further research into the diagnosis and treatment of EC in pediatric populations is warranted.

338
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...

01:28Acute Pyelonephritis II: Diagnostic Studies and Management
161
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...

256
Pyelonephritis is a bacterial infection that primarily affects the renal parenchyma and collecting system, including the renal pelvis, tubules, and interstitial tissue of one or both kidneys. It can be classified as either acute—a sudden, severe infection—or chronic, which refers to long-term or recurrent kidney infections.The primary cause of acute pyelonephritis (APN) is bacterial infection, with Escherichia coli accounting for approximately 70-80% of cases. Other bacteria, such...

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...

01:26Urinary Tract Infection I: Introduction
309
Urinary tract infections (UTIs) impact various parts of the urinary system, including the kidneys, ureters, bladder, and urethra. These infections are generally bacterial, with Escherichia coli being the most common causative agent, often originating from the gastrointestinal tract. However, other bacteria, such as Staphylococcus saprophyticus, Klebsiella pneumoniae, and Proteus mirabilis, are also known to cause UTIs. The type, location, and underlying complexity of the UTI guide both...

01:26Urine Studies II: Urine Culture and Sensitivity Test
402
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...
