BACKGROUND: Antibodies to neuronal extracellular membrane antigens, including the NR1 subunit of the N-methyl-D-aspartate receptor, have been associated with neuropsychiatric symptoms. In 2003, the first case of anti-NMDA receptor encephalitis was identified in a young woman with subacute onset of ehavioural changes and seizures.
OBJECTIVES: The aim of this case report is to describe the clinical features, disease course and management of a documented case of anti-NMDA receptor encephalitis in the Philippines. It also aims to highlight a unique feature of the disease as seen in the patient.
CASE DESCRIPTION: The patient is a 36-year-old female with no known co-morbidities presenting with subacute onset of ehavioural change and generalized seizures. She was initially worked-up for viral encephalitis but the diagnostic tests were negative. With a suspicion of anti-NMDA receptor encephalitis, a search was made for the presence of a teratoma. This was confirmed by imaging studies and subsequent surgical resection of an immature mesenteric teratoma was done. Immunohistochemical assay of both blood and CSF were positive for NMDAR antibodies.
CONCLUSION: This is the first confirmed case of anti-NMDA receptor encephalitis reported in the Philippines. It has the unique feature of being associated with an immature mesenteric teratoma, a finding that has not been reported in literature. The possibility of anti-NMDAR encephalitis need to be considered among patients with subacute onset of ehavioural changes and seizures when usual diagnostic tests for the more common etiologies prove negative.

OBJECTIVES: To assess the validity of the Filipino-translated version of the Michigan Neuropathy Screening Instrument(MNSI) in screening for diabetic neuropathy among Filipino patients with diabetes mellitus using nerve conduction velocity(NCV) as gold standard and to determine the most accurate cut-off score for the diagnosis of neuropathy using MNSI.
METHODOLOGY: A cross-sectional analytic study was done among adult diabetic patients. The original MNSI Questionnaire was translated and back-translated to the Filipino language. Each patient answered the Filipino version of MNSI Questionnaire followed by a lower extremity examination done by the investigator. All patients underwent NCV as reference standard. Sensitivity and specificity of MNSI were determined.
RESULTS: We studied a total of 150 subjects. Eighty-seven (58%) were diagnosed to have diabetic neuropathy based on NCV. The sensitivity and specificity of the MNSI Questionnaire improved to 73.6% and 52.4% respectively when the cut off was reduced to ?4, whereas for the MNSI Examination, the sensitivity and specificity improved to 86.2% and 55.6% respectively when the cut off was reduced to ?1. Combining both MNSI Questionnaire and MNSI Examination further improves the sensitivity to 95.4% whereas specificity is at 39.7%.
CONCLUSION: The analyses in 150 subjects confirm that the Filipino-version of MNSI is a valid screening tool for diabetic neuropathy when compared with NCV as gold standard.
