A Comparison of Pediatric- and Adult-Onset Aquaporin-4 Immunoglobulin G-Positive Neuromyelitis Optica Spectrum Disorder: A Review of Clinical and Radiographic Characteristics.

Background: The identification of immunoglobulin G antibodies against the aquaporin-4 channel (AQP-IgG) in the majority of adult patients differentiates neuromyelitis optica as a distinct disease entity. The high specificity of AQP4-IgG for neuromyelitis optica has allowed the identification of seropositive patients with atypical presentations of this disease. Neuromyelitis optica spectrum disorder has been increasingly recognized in children who demonstrate patterns of clinical involvement beyond the traditional boundaries of the optic pathways and spinal cord.

Polarization and angular insensitive bendable metamaterial absorber for UV to NIR range.

Broadband absorbers are required for solar energy harvesting because they efficiently absorb the incident photon in the wide-ranging solar spectrum. To ensure high absorption of photons, metamaterial absorbers (MMAs) have been a growing area of interest in recent years. In this article, an MMA is proposed using a metal-insulator-metal (MIM) structure (Ni-SiO-Ni) that shows a near-unity broadband absorption of wavelengths from 300 to 1600 nm, with a 95.

Vitamins are Indeed Vital Amines: A Discussion of 3 Deficiencies With Neurologic Manifestations.

Optimal functioning of the human nervous system depends on a constant supply of nutrients, vitamins, and minerals. In the developed world, nutritional deficiencies are relatively rare and infrequently present with neurologic manifestations. These neurologic disorders can be mistaken for inflammatory and/or autoimmune phenomena.

An Unusual Visit from an Old Foe: Oral Presentation of Syphilis in a Teenage Patient.

The authors report an atypical case of secondary syphilis in an adolescent female presenting to a tertiary-care center with fever, weight loss, oral sores, painful inguinal lymphadenopathy, and transient macular rash. Given the lower prevalence of syphilis in adolescent females, this infection was not included on the initial differential diagnosis. The evolving presentation of syphilis over time complicates the diagnosis and management of these infections, as it did for the patient in this report.

Are There Racial Disparities in Family-Reported Experiences of Care in Inpatient Pediatrics?

Despite increased emphasis on patient satisfaction as a quality measure in health care, little is known about the influence of race in parent-reported experience of care in pediatrics. This study evaluates the association of race with patient satisfaction scores in an inpatient pediatric tertiary care hospital in one year. Risk-adjusted multivariable logistic regression was performed to evaluate the association of minority race with the likelihood to provide a top-box (=5) satisfaction score for 38 individual questions across 8 domains.
