Summary
Streptococcus pyogenes can cause cervical intertrigo in infants, a condition often underestimated. Early diagnosis with antigen tests is key, especially as this case developed bacteremia, a new complication.
Area of Science:
- Pediatrics
- Dermatology
- Infectious Diseases
Background:
- Cervical intertrigo is a common inflammatory skin condition in infants.
- Bacterial causes of intertrigo are less common than fungal infections.
- Streptococcus pyogenes is a known pathogen but rarely associated with intertrigo.
Observation:
- A 12-month-old infant girl presented with cervical intertrigo.
- The lesions were well-demarcated and beefy-red, unresponsive to antifungal treatment.
- The infant developed Streptococcus pyogenes bacteremia.
Findings:
- Cervical intertrigo in this infant was caused by Streptococcus pyogenes.
- A rapid streptococcal antigen test confirmed the diagnosis.
- This is the sixth reported case of cervical intertrigo due to S. pyogenes in children.
- S. pyogenes bacteremia is a newly identified complication of this condition.
Implications:
- Cervical intertrigo caused by S. pyogenes may be underdiagnosed.
- Clinicians should consider bacterial causes, particularly S. pyogenes, in refractory intertrigo.
- Rapid antigen testing can aid in prompt diagnosis and treatment.
- The development of bacteremia highlights the potential severity and need for vigilant monitoring.

1.5K
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...

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

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...

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...

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...

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
