Etiology of cervical lymphadenitis in children
Insights
Group A beta-hemolytic streptococci and Staphylococcus aureus were common causes of pediatric cervical lymphadenopathy. Infectious mononucleosis was also a frequent diagnosis, with some cases involving multiple pathogens. Etiologic agents were not identified in all children.
Area of Science:
- Pediatric Infectious Diseases
- Microbiology
- Otolaryngology
Background:
- Cervical lymphadenopathy is a common condition in children.
- Identifying the causative agent is crucial for appropriate treatment.
- Various bacterial and viral pathogens can lead to cervical lymphadenopathy.
Purpose of the Study:
- To determine the etiologic agents responsible for cervical lymphadenopathy in children.
- To analyze the prevalence of different pathogens in pediatric cases.
- To identify cases where no specific agent was found.
Main Methods:
- Retrospective evaluation of 30 children under 17 with cervical lymphadenopathy.
- Microbiological and serological testing to identify causative agents.
- Clinical data analysis to correlate findings with diagnoses.
Main Results:
- Group A beta-hemolytic streptococci identified in 33% of cases.
- Staphylococcus aureus and infectious mononucleosis each found in 4 patients.
- Co-infections noted, and no etiologic agent identified in 27% of children.
Conclusions:
- Bacterial infections, particularly Group A Streptococcus, are leading causes of pediatric cervical lymphadenopathy.
- Infectious mononucleosis is another significant contributor.
- A notable proportion of cases remain without a confirmed etiologic diagnosis, warranting further investigation.
Abstract:
Thirty children under 17 years of age with cervical lymphadenopathy were evaluated. Lymphadenitis was attributed to Group A beta-hemolytic streptococci in 10 of the patients (33 percent), to Staphylococcus aureus in four and to infectious mononucleosis in four. Two patients had both infectious mononucleosis in Group A beta-hemolytic streptococci. One child was affected with Acinetobacter with calcoaceticus (mima) and another with mycobacteria. In eight children (27 percent), no etiologic agent could be found.
