Insights
Neonatal osteomyelitis in infants is often diagnosed early and can affect multiple sites. A shift in causative bacteria from Staphylococcus aureus to group B beta-hemolytic streptococci occurred between 1951-1976.
Area of Science:
- Pediatrics
- Infectious Diseases
- Orthopedic Surgery
Background:
- Neonatal osteomyelitis presents unique challenges in diagnosis and treatment.
- Understanding shifts in causative pathogens is crucial for effective management.
Purpose of the Study:
- To evaluate conservative (nonsurgical) therapy for neonatal osteomyelitis.
- To document changes in the primary etiologic agents causing osteomyelitis in newborns.
Main Methods:
- Retrospective review of 45 infant cases of osteomyelitis admitted between 1951-1976.
- Analysis of disease characteristics, causative agents, treatment, and outcomes.
Main Results:
- Most cases (73%) were diagnosed within the first two weeks of life.
- Distinctive infection patterns included multiple foci, facial bones, and contiguous joint involvement.
- A significant shift in etiology was observed: Staphylococcus aureus predominated before 1965, followed by group B beta-hemolytic streptococci from 1965-1976.
Conclusions:
- Conservative therapy is a viable option for most infants with neonatal osteomyelitis.
- The changing landscape of etiologic agents necessitates ongoing surveillance and adaptive treatment strategies.
Abstract:
To evaluate current conservative therapy and document the existence of a recent shift in etiologic agents, we reviewed the records of 45 infants who developed osteomyelitis within the first ten weeks of life and who were admitted to Babies Hospital (New York) from 1951 through 1976. Emphasis was placed on characteristics and course of the disease, etiologic agents, therapy, and outcome. Illness was diagnosed within the first two weeks of life in 34 of the 45 infants (73%). Only six had been delivered normally after normal pregnancy and led a normal life before development of ostemyelitis. Infected sites were distinctive in frequency of involvement of multiple foci (21), of facial bones (10), and of joints contiguous to infected long bones (22 of 29). Conservative therapy (nonsurgical) seems reasonable for the majority of patients. Of particular interest is documentation of a shift from Staphylococcus aureus as predominant etiologic agent before 1965 to beta-hemolytic streptococci, commonly group B, from 1965 through 1976. Data collected from the literature of the 1930s indicate that such shifts have occurred before.
