Insights
This study evaluated children with subdural empyema (SDE) and brain abscess (BA), finding that while mortality is low, neurological complications remain high. Early diagnosis and treatment of these pediatric intracranial infections are crucial.
Area of Science:
- Pediatric Neurology
- Infectious Diseases
- Neurosurgery
Background:
- Intracranial suppuration, including subdural empyema (SDE) and brain abscess (BA), is a serious condition in children.
- Understanding the specific characteristics and outcomes of SDE and BA is vital for effective management.
Purpose of the Study:
- To determine the prevalence, age distribution, predisposing factors, bacteriology, clinical features, and outcomes of pediatric SDE and BA.
- To identify differences in presentation and outcomes between SDE and BA in children.
Main Methods:
- A retrospective hospital-based study was conducted.
- Clinical data of children diagnosed with SDE or BA over 10.75 years at a tertiary children's hospital were reviewed.
Main Results:
- Forty-six children with intracranial suppuration were identified (26 BA, 16 SDE, 4 both).
- Sinusitis was a predisposing factor for SDE; Streptococcus milleri was common in SDE. Periorbital edema and photophobia were associated with SDE.
- Mortality was low (3/46), but neurological complications were high (54.3%), more frequent in BA. Outcomes varied by age, with peaks for SDE at <2 and >7 years, and for BA at 9-11 years.
Conclusions:
- Intracranial suppuration in children has a low mortality rate but high morbidity.
- Prompt diagnosis and treatment are essential to improve outcomes and reduce neurological deficits.
Objective:
To evaluate prevalence, age, position, predisposing factors, bacteriology, clinical features and outcomes of children with subdural empyema (SDE) and brain abscess (BA).
Design:
Retrospective hospital-based study in a tertiary children's hospital.
Methods:
Clinical data were reviewed on all children classified as having SDE or BA for 10.75 years from 1 January 1992 to 31 August 2003 at the Royal Alexandra Hospital for Children, Sydney, Australia.
Results:
Forty-six children with intracranial suppuration were identified: 26 had BA, 16 had SDE and four children had both SDE and BA. Significant differences between SDE and BA were that: sinusitis was a predisposing factor for SDE (P = 0.01), Streptococcus milleri was the main organism isolated in SDE (P = 0.02), periorbital oedema (P = 0.005) and photophobia (P = 0.02) were clinical features specifically associated with SDE, and 75% of multiple abscesses were in females (P = 0.005). The age distribution of SDE was biphasic, with peaks at <2 years and >7 years. Cases of BA peaked at age 9-11 years. Forty-eight per cent of all children were between 9 and 13 years old; 20% were <1 year old. All the children with SDE and BA were aged 1 year or less. Three of the 46 children died, all with BA. Eighteen (39.1%) returned to normal and 25 (54.3%) had neurological complications. Neurological complications were more common in the BA group.
Conclusion:
The mortality rate of intracranial suppuration is low, but morbidity remains high. A high degree of suspicion is needed to diagnose and treat intracranial infections early.
