Summary
This case report details a rare pediatric joint infection caused by Bacillus cereus (B. cereus) septic arthritis. Prompt diagnosis and multidisciplinary management led to an excellent recovery and full mobility for the child.
Area of Science:
- Pediatric infectious diseases
- Orthopedic surgery
- Microbiology
Background:
- Joint infections in children are uncommon.
- Infections caused by Bacillus cereus are exceptionally rare in pediatric populations.
- Extra-intestinal Bacillus cereus infections are seldom seen in immunocompetent individuals.
Observation:
- A previously healthy child presented with symptoms of septic arthritis in the left knee.
- Arthroscopy and debridement were performed, with synovial fluid cultures identifying Bacillus cereus.
- This represents the first reported case of Bacillus cereus septic arthritis in a pediatric patient.
Findings:
- The patient received a treatment regimen of intravenous vancomycin followed by oral ciprofloxacin.
- The child experienced an excellent clinical outcome, regaining full mobility without residual limitations.
- Multidisciplinary collaboration was crucial for managing this rare pediatric infection.
Implications:
- This case highlights the importance of considering rare pathogens, even when they are environmental contaminants.
- Early recognition and appropriate management of Bacillus cereus septic arthritis can lead to favorable outcomes in children.
- Clinicians should be aware of the potential for Bacillus cereus to cause severe joint infections in pediatric patients.

26
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...

01:27Acute Pyelonephritis I: Introduction
30
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...

Coryneform bacteria are gram-positive, aerobic, nonmotile rods that exhibit irregular, club-shaped, or V-shaped arrangements. Their V-shape results from snapping division, where the inner cell wall layer forms the cross-wall, while the outer layer remains intact until it ruptures on one side, causing the daughter cells to bend away.The primary genera are Corynebacterium and Arthrobacter. Corynebacterium includes diverse species, ranging from saprophytes to pathogens like Corynebacterium...

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

Spirochetes, unique bacteria in the phylum Spirochaetes, are gram-negative, motile, tightly coiled, slender, and flexible. They inhabit aquatic sediments and animals, with some causing diseases like syphilis. Spirochetes are classified into eight genera based on habitat, pathogenicity, phylogeny, and characteristics.Their distinctive motility arises from endoflagella, located within the cell’s periplasm. These endoflagella anchor at the cell poles and extend along the cell length, encased...

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...
