Insights
Pediatric acute bacterial sinusitis (ABS) treatment is challenged by rising antibiotic resistance and changing pathogens. Clinicians need education on diagnosis and judicious antibiotic use for effective management.
Area of Science:
- Pediatric infectious diseases
- Microbiology
- Pharmacology
Background:
- Acute bacterial sinusitis (ABS) is a common pediatric infection.
- Emerging challenges impact the effective treatment of ABS.
Purpose of the Study:
- To review and summarize recent challenges in the microbiology and treatment of pediatric acute bacterial sinusitis (ABS).
Main Methods:
- A literature review of medical publications from 1990 to 2006 was conducted.
- Searches were performed using the National Library of Medicine's PUBMED database.
Main Results:
- Penicillin resistance mechanisms include porin channel blockage, beta-lactamase production, and altered penicillin-binding proteins (PBPs).
- Shifts in causative pathogens, similar to those seen in acute otitis media (AOM) post-PCV7 vaccine, are observed in pediatric ABS.
- Bacterial interference and evolving resistance patterns like beta-lactamase-negative ampicillin resistance (BLNAR) complicate treatment.
Conclusions:
- Treatment of pediatric ABS is complicated by increasing pathogen resistance and multi-drug resistance.
- Accurate diagnosis differentiating viral from bacterial sinusitis is crucial before antibiotic therapy.
- Clinician education on emerging resistance, bacterial interference, and patient adherence factors is vital for judicious ABS treatment.
Objective:
To review and summarize recent challenges in the microbiology and treatment of acute bacterial sinusitis (ABS), one of the most common infectious diseases in the pediatric community.
Methods:
A review of recent medical literature from 1990 to 2006 was acquired using the National Library of Medicine's PUBMED database.
Results:
Multiple mechanisms of penicillin resistance have been identified: porin channel blockage, beta-lactamase production, and changes in penicillin-binding proteins (PBPs). Other factors affecting treatment efficacy include the role of normal nasopharyngeal flora, such as alpha-streptococci. The more widely documented shift in the causative pathogens of acute otitis media (AOM) following the release of the heptavalent pneumococcal conjugate vaccine (PCV7) has also been documented in two studies of ABS in children.
Conclusions:
Treatment of ABS in children is complicated by a number of emerging changes in pathogen resistance patterns. These include beta-lactamase-negative ampicillin resistance (BLNAR) and multi-drug resistance, bacterial interference, and geographic data. These phenomena are likely to impact the treatment of URIs. Appropriate diagnosis and differentiation from viral sinusitis is essential prior to initiating therapy. Clinician education about these emerging issues remains an important strategy in diagnosing and treating ABS in children. This includes an understanding of known patient adherence to antibiotic therapy, such as taste, tolerability, dosing schedule, therapy duration, and patient preference. Clinicians should review judicious ABS treatment approaches that employ agents with documented efficacy against implicated pathogens.

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:

Etiology
Three primary contributing factors have been identified.

01:23Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
