Clinical characteristics and outcomes of paediatric orbital cellulitis in Hospital Universiti Sains Malaysia: a five-year review.

Limited data is available on paediatric orbital cellulitis in Asia. We aimed to describe demographic data, clinical presentation, predisposing factors, identified microorganisms, choice of antibiotics and management in children with orbital cellulitis treated in a tertiary care centre in Malaysia. A retrospective review was performed on children with orbital cellulitis aged below 18 years who were admitted to Hospital Universiti Sains Malaysia, Kelantan, Malaysia, between January 2013 and December 2017. A total of 14 paediatric patients fulfilling the diagnostic criteria for orbital cellulitis were included. Their mean age was 6.5 ± 1.2 years. Boys were more likely to have orbital cellulitis than girls (71.4% vs. 28.6%). Involvement of both eyes was observed in 14.3% of the patients. Sinusitis (28.6%) and upper respiratory tract infection (21.4%) were the most common predisposing causes. Staphylococcus aureus (28.6%) was the leading pathogen. Longer duration of hospitalisation was observed in those infected with methicillin-resistant Staphylococcus aureus and Burkholderia pseudomallei. 10 (71.4%) patients were treated with a combination of two or three antibiotics. In this series, 42.9% had surgical interventions. Young boys were found to be more commonly affected by orbital cellulitis than young girls. Staphylococcus aureus was the most common isolated microorganism. Methicillin-resistant Staphylococcus aureus and Burkholderia pseudomallei caused severe infection. Sinusitis and upper respiratory tract infection were the most common predisposing factors. A majority of the children improved with medical treatment alone. Our findings are in slight disagreement with other published reports on paediatric orbital cellulitis, especially from the Asian region.
