Summary of "Neuromyelitis optica spectrum disorder in a tertiary hospital in the Philippines: a case series."

Neuromyelitis optica spectrum disorder (NMOSD) is a rare disease that commonly presents with optic nerve and spinal cord inflammation, and it is associated with the presence of aquaporin-4 immunoglobulin G antibody (AQP4-IgG). Information on the clinical profile and occurrence of NMOSD among Filipino patients, however, is not sufficiently documented. In this series, we presented eighteen (18) patients with NMOSD consecutively seen in the Philippine General Hospital, a major tertiary referral center. Demographic data showed a female-to-male ratio of 2.6:1. Median age of onset of symptoms was 26 years. Eight patients (53.3%) were positive for AQP4-IgG. Most patients initially presented with myelitis (56.6%) and followed by optic neuritis (16.7%) and area postrema syndrome (16.7%). All patients had longitudinally extensive transverse myelitis on magnetic resonance imaging (MRI). Cranial MRI rarely demonstrated lesions in the optic nerves (18.2%). CSF pleocytosis (33%) and increased protein (8.3%) were infrequent. These results demonstrated that the profile of Filipino patients with NMOSD seen in our institution strengthens those described in other populations with this disorder. Large scale cross-sectional studies are necessary to fully define the profile of these patients and to determine with accuracy the prevalence and incidence of this disorder in the Philippines. Further investigation regarding the utility of ancillary tests as diagnostic and prognostic indicators in patients with NMOSD are also suggested by the authors.

Medical and Biotech [MESH] Definitions

A syndrome characterized by acute OPTIC NEURITIS in combination with acute MYELITIS, TRANSVERSE. Demyelinating and/or necrotizing lesions form in one or both optic nerves and in the spinal cord. The onset of optic neuritis and myelitis may be simultaneous or separated by several months. (J Neurol Neurosurg Psychiatry 1996 Apr;60(4):382-387)

A system for classifying patient care by relating common characteristics such as diagnosis, treatment, and age to an expected consumption of hospital resources and length of stay. Its purpose is to provide a framework for specifying case mix and to reduce hospital costs and reimbursements and it forms the cornerstone of the prospective payment system.

The expenses incurred by a hospital in providing care. The hospital costs attributed to a particular patient care episode include the direct costs plus an appropriate proportion of the overhead for administration, personnel, building maintenance, equipment, etc. Hospital costs are one of the factors which determine HOSPITAL CHARGES (the price the hospital sets for its services).

An isomer of butanol that contains a tertiary butyl group that consists of three methyl groups, each separately attached to a central (tertiary) carbon.

The prices a hospital sets for its services. HOSPITAL COSTS (the direct and indirect expenses incurred by the hospital in providing the services) are one factor in the determination of hospital charges. Other factors may include, for example, profits, competition, and the necessity of recouping the costs of uncompensated care.
