ABSTRACT
AIM: To assess the prevalence of clinically urgent intracranial pathology (CUIP) in children visiting the emergency department with a complex febrile seizure (CFS). METHODS: Retrospective cohort review. We analysed the visits of patients for a CFS from January 2007 to December 2011 in seven paediatric emergency departments. Our main outcomes were the proportions of CUIP diagnosed between day 0 and 1 and within 30 days after the index visit. RESULTS: From 1 183 487 visits, 839 were for a CFS and 130 (15.5%) of these had a neuroimaging performed within 30 days (CT scan for 75 visits [8.9%], MRI for 30 visits [3.6%] and both for 25 visits [3.0%]). Three CUIP were diagnosed between day 0 and 1 (0.4% [CI-95%: 0.1-1.3]), 5 within 30 days after the index visit (0.7% [CI-95%: 0.2-1.7]) but none among the 630 visits of children presenting with a normal neurological clinical examination (0% [95% CI: 0.0-0.7]), nor among the 468 presenting only with multiple seizure (0% [95% CI: 0.0-1.0]). CONCLUSION: In children with a CFS, CUIP is rare event in the subgroup of children with a normal neurological clinical examination and in those with brief generalised multiple seizures.

STUDY OBJECTIVE: We assess the prevalences of bacterial meningitis and herpes simplex virus meningoencephalitis (HSV-ME) in children with a complex febrile seizure and determine these prevalences in the subgroup of children with a clinical examination result not suggestive of meningitis or encephalitis. METHODS: This multicenter retrospective study was conducted in 7 pediatric emergency departments (EDs) in the region of Paris, France. Visits of patients aged 6 months to 5 years for a complex febrile seizure from January 2007 to December 2011 were analyzed. We defined a subgroup of patients whose clinical examination result was not suggestive of meningitis or encephalitis. Bacterial meningitis and HSV-ME were sequentially sought for by analyzing bacteriologic and viral data at the visit, looking for data from a second visit to the hospital after the index visit, and telephoning the child's parents. RESULTS: From a total of 1,183,487 visits in the 7 pediatric EDs, 839 patients presented for a complex febrile seizure, of whom 260 (31.0%) had a lumbar puncture. The outcomes bacterial meningitis and HSV-ME were ascertainable for 715 (85%) and 657 (78.3%) visits, respectively, and we found 5 cases of bacterial meningitis (0.7% [95% confidence interval [CI] 0.2% to 1.6%]) and no HSV-ME (0% [95% CI 0% to 0.6%]). Among the 630 visits of children with a clinical examination result not suggesting meningitis or encephalitis, we found no bacterial meningitis (0% [95% CI 0% to 0.7%]) and no HSV-ME (0% [95% CI 0% to 0.8%]). CONCLUSION: In children with a complex febrile seizure, bacterial meningitis and HSV-ME are unexpected events when the clinical examination after complex febrile seizure is not suggestive of meningitis or encephalitis.

OBJECTIVES: National and international guidelines are very heterogeneous about the necessity to perform a lumbar puncture (LP) in children under 12 months of age with a first simple febrile seizure. We estimated the risk of bacterial meningitis in children aged 6 to 11 months with a first simple febrile seizure. METHODS: This multicenter retrospective study was conducted in seven pediatric emergency departments (EDs) in the region of Paris, France. Visits of patients aged 6 to 11 months for a first simple febrile seizure from January 2007 to December 2011 were analyzed. Bacterial meningitis was sequentially sought for by 1) analyzing bacteriologic data at the time of the visit, 2) looking for data from a second visit to the hospital after the index visit, and 3) phone calling the child's parents to determine the symptom evolution after the index visit. Infants lost to this follow-up were searched for in a national bacterial meningitis database. RESULTS: From a total of 1,183,487 visits in the seven pediatric EDs, 116,503 were for children 6 to 11 months of age. From these, 205 visits were for a first simple febrile seizure. An LP was performed in 61 patients (29.8%). The outcome bacterial meningitis was ascertainable for 168 (82%) visits. No bacterial meningitis was found among these patients (95% confidence interval = 0% to 2.2%). None of the 37 infants lost to our follow-up were registered in the national database as having bacterial meningitis. CONCLUSIONS: Among children between 6 and 11 months of age with a first simple febrile seizure, the risk of bacterial meningitis is extremely low. These results should encourage national and international societies to either develop or endorse guidelines limiting routine LP in these infants and contribute to widely homogenized management practices.
