Objective:
Bacterial meningitis is associated with significant morbidity and mortality if not diagnosed and treated early. Isolation of the causative agent from cerebrospinal fluid culture is the gold standard for the diagnosis of this condition; however, it takes several days for results to be available. The FilmArray™ Meningitis/Encephalitis (ME) panel is a nucleic acid-based test that allows simultaneous detection of 14 bacterial, viral, and fungal pathogens in the cerebrospinal fluid with a rapid turnaround time. Our aim was to evaluate the diagnostic performance of the ME panel in detecting bacterial pathogens in the cerebrospinal fluid of adult patients with suspected bacterial meningitis in a tertiary hospital in the Philippines.
Methods:
We performed a retrospective review of hospital records of adult patients with suspected bacterial meningitis who were admitted at our institution and underwent diagnostic testing with the FilmArray™ ME panel from January 1, 2018 to July 31, 2019. Overall percent agreement, sensitivity, and specificity for individual bacterial pathogens included in the panel were determined.
Results:
A total of 88 cerebrospinal fluid samples were included in the analysis of diagnostic accuracy. The ME panel demonstrated 93.2% overall agreement, 50% sensitivity for E. coli, and 99–100% specificity in comparison with CSF culture in detecting bacterial pathogens that are included in the ME panel.
Conclusion
The results show that the FilmArray™ ME panel has high diagnostic accuracy and can be utilized in the rapid diagnosis and targeted treatment of patients with suspected bacterial meningitis.

Background & Objectives: Stroke mimics are conditions that simulate the signs and symptoms of a
stroke. These conditions pose a clinical challenge as they need to be distinguished from actual strokes
based on neurologic findings, laboratory tests, and imaging studies in order to minimize the adverse
effects of acute stroke therapies as well as hospital costs. The study aims to determine the rate and
the most common etiologies of stroke mimics in a private tertiary care hospital in the Philippines and
calculate the average cost incurred for diagnostics. Methods: We conducted a retrospective review of
medical records of adult patients assessed by the hospital’s Brain Attack Team from 1 January 2014
to 31 December 2017. The diagnosis of stroke mimic was based on negative neuroimaging findings
and laboratory results that showed an alternate diagnosis, in consultation with the stroke neurologist
on call. Results: A total of 1,485 patient records were analyzed; 448 patients (30.2%) were diagnosed
as stroke mimics. The most common etiologies were encephalopathy (83 cases, 18.5%), seizures (77
cases, 17.2%), headache (31 cases, 6.9%), hypertensive emergency (31 cases, 6.9%), and radiculopathy
(27 cases, 6.0%). The average cost for diagnostics for each patient diagnosed as a stroke mimic was
PHP 24,629.53 (approximately US$500).
Conclusion: Stroke mimics are often encountered in the emergency setting. Due to the wide range of
medical conditions that mimic stroke, early recognition is important in order to avoid the potential
adverse effects of acute stroke therapies and minimize diagnostic costs, particularly in countries with
limited resources.
