ABSTRACT
OBJECTIVE: To describe the utility of film array meningoencephalitis (FAME) panel in the management of children with acute encephalitis syndrome (AES). METHODS: A retrospective audit was conducted between January 2017 to July 2022. We included children aged < 18 years with a diagnosis of AES for whom a CSF analysis study including FAME panel testing performed within 48 hours of admission was available. Electronic medical records were reviewed for details including demographic profile, clinical presentation, investigations and outcome. RESULTS: Out of 157 CSF samples sent for FAME panel testing, 49 were positive (31.4%.) Viral pathogens were identified in 42 (Enterovirus: 31, Human herpes virus 6: 9, Varicella zoster virus: 1, and Cytomegalovirus: 1) Bacterial pathogens were identified in 6 (Streptococcus pneumoniae: 2, Streptococcus agalactiae: 2, Hemophilus influenzae: 1, and Escherischia coli: 1). Fungal etiology (Cryptococcus neoformans) was detected in one child. Antibiotics could be stopped within 72 hours of initiation in 42 children in whom a viral etiology was established. Acyclovir could be stopped in 21 out of 32 children within 72 hours after the FAME panel testing. FAME panel was presumed to be false positive in 4 children. CONCLUSION: Etiology of AES could be established in nearly a third of children with AES using the rapid diagnostic FAME panel testing in CSF and it was found to be effective in reducing empirical antibiotic/antiviral therapy.

Pontocerebellar hypoplasia is a heterogeneous group of disorders characterized by abnormally small cerebellum and brainstem. Pontocerebellar hypoplasia type 1 is associated with spinal anterior horn cell degeneration, microcephaly, congenital contractures, polyhydramnios, and respiratory insufficiency leading to death in infancy. Recently, however, the spectrum of this disease has been extended to include less severe variants, some of which are associated with minimal atrophy of the brainstem. In two reported cases of late-onset variant pontocerebellar hypoplasia, the siblings were alive at 9 years and 6 years, respectively, but were severely crippled and anarthric; they had features of anterior horn cell involvement and cerebellar atrophy but the brainstem was spared. The present case is that of a 12-year-old boy with early onset of anterior horn cell involvement and slowly progressive cerebellar ataxia who is still able to walk with support and speak in sentences. He was found to be devoid of the exon 7 and exon 8 deletion of the survival motor neuron gene seen in classical spinal muscular atrophy, and magnetic resonance imaging indicated marked atrophy of the cerebellar vermis and hemispheres, with minimal involvement of the brainstem. This form is apparently the mildest variant of pontocerebellar hypoplasia type 1 described to date.
