Epidemiology of acute haematogenous osteomyelitis in children--a single unit's experience over three different...

Area of Science:

• Pediatric infectious diseases
• Epidemiology
• Orthopedic surgery

Background:

• Osteomyelitis is a serious bone infection in children.
• Understanding epidemiological trends is crucial for public health planning.
• Changes in diagnostic and treatment modalities may impact disease patterns.

Purpose of the Study:

• To compare the epidemiology of acute hematogenous osteomyelitis (AHO) in children over three distinct time periods.
• To evaluate changes in diagnostic methods and treatment strategies for pediatric osteomyelitis.
• To assess the incidence and clinical presentation of AHO in a defined English health district.

Main Methods:

• Retrospective epidemiological study comparing AHO cases from 2000-2005 with historical data from 1982-1986 and 1947-1951.
• Analysis of patient demographics, causative organisms, diagnostic imaging sensitivities, and surgical intervention rates.
• Calculation of annual incidence rates based on total population.

Main Results:

• The annual incidence of AHO was 0.4 per 100,000 population in the most recent period.
• The mean age of presentation (40 months) was significantly lower in the 2000-2005 cohort compared to earlier periods.
• Staphylococcus species was the most common pathogen; MRI and nuclear medicine showed higher diagnostic sensitivity than plain radiography.
• Surgical intervention rates were halved between 1947-1951 and 2000-2005.

Conclusions:

• While a definitive decrease in AHO incidence was not established, significant evolution in clinical management is evident.
• Diagnostic imaging and surgical approaches have advanced, potentially influencing disease presentation and outcomes.
• Continued epidemiological surveillance is necessary to monitor trends in pediatric osteomyelitis.
