Summary
This case report details the first instance of septic prepatellar bursitis caused by Kingella kingae in a child. Early diagnosis and treatment are vital for preventing complications from this difficult-to-culture bacterium.
Area of Science:
- Pediatric Infectious Diseases
- Microbiology
- Orthopedic Surgery
Background:
- Kingella kingae is a known cause of pediatric osteoarticular infections.
- Septic bursitis is an infection of the bursa, commonly affecting the knee.
- Previous literature has not identified K. kingae as a cause of septic bursitis.
Observation:
- A 2-year-old female presented with septic prepatellar bursitis.
- K. kingae was identified as the causative pathogen.
- Diagnosis was confirmed via bursal fluid analysis; oropharyngeal PCR is a potential alternative.
Findings:
- This is the first reported case of septic prepatellar bursitis due to K. kingae.
- The case highlights K. kingae's potential role in periarticular infections.
- Pathophysiology in children may resemble pediatric osteomyelitis.
Implications:
- A high index of suspicion for K. kingae is necessary for diagnosing challenging pediatric infections.
- K. kingae should be considered in pediatric osteoarticular and periarticular infections when cultures are negative.
- Prompt diagnosis and intervention, including surgical debridement if needed, are critical to avoid severe outcomes.

230
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...

382
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...

491
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...

01:25Endocarditis I: Introduction
322
Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

305
Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...
