Periorbital cellulitis in infancy
Insights
Infantile periorbital cellulitis differs between neonates and older infants. Neonates show more ruptured dacryocele and unknown infection sources, while older infants have more upper respiratory infections and positive blood cultures.
Area of Science:
- Ophthalmology
- Pediatrics
- Infectious Diseases
Background:
- Periorbital cellulitis is an infection of the eyelid and surrounding skin.
- Infantile periorbital cellulitis, particularly in neonates, has distinct characteristics not well-documented.
- Understanding these differences is crucial for accurate diagnosis and treatment in infants.
Purpose of the Study:
- To investigate the specific clinical features, etiology, and outcomes of infantile periorbital cellulitis.
- To compare characteristics between neonates (under 1 month) and older infants (over 1 month).
Main Methods:
- Retrospective study of 30 infantile periorbital cellulitis cases treated between 1977 and 1988.
- Analysis of patient demographics, clinical presentation, radiological findings, bacteriology, and treatment course.
- Comparison of characteristics between neonates and older infants.
Main Results:
- Infants over 1 month shared similarities with older children regarding etiology and course.
- Neonates (7-30 days old) had a higher incidence of ruptured dacryocele (29%) and unknown infection source (43%).
- Neonates had lower rates of preceding upper respiratory infection (14%), abnormal sinus films (0%), and positive blood cultures (14%) compared to older infants. *Hemophilus sp* was common in older infants, while *Streptococcus* and *Staphylococcus* predominated in neonates.
Conclusions:
- Infantile periorbital cellulitis presents differently in neonates versus older infants.
- Ruptured dacryocele and unidentified infection sources are more prevalent in neonates.
- Prompt antibiotic treatment is effective, with all cases remaining preseptal.
Abstract:
To our knowledge, no previous study of periorbital cellulitis has focused on its specific characteristics found only in infants (less than 1 year of age.) We retrospectively studied 30 cases of infantile periorbital cellulitis treated at Harbor-UCLA Medical Center from 1977 to 1988. Characteristics of the disorder in our infants older than 1 month were similar to earlier reports of older children in terms of etiology, radiological and bacteriological findings, and course. However, compared with our older infants, our seven neonates (7 to 30 days old) had a higher incidence of ruptured dacryocele (29% vs 0%) and unknown source of the infection (43% vs 4%); but a lower incidence of preceding upper respiratory infection (14% vs 78%), abnormal sinus films (0% vs 22%), and positive blood cultures (14% vs 30%). Of the positive cultures, Hemophilus sp was the most common pathogen among the older infants (35%), while Streptococcus and Staphylococcus were the most frequent among the neonates (71%). All infections remained preseptal and responded well to intravenous antibiotics.
