Pediatric Resident Confidence in Assessing Neurological Cases: A Nationwide Survey.

Background: A relative shortage of pediatric neurologists in proportion to estimated neurological disorders often results in general pediatricians evaluating and treating children with complex neurological conditions. Dedicated rotations in pediatric neurology are not mandated during medical school or pediatric residency. We evaluated the perceptions of a large cohort of pediatric residents and program directors (PDs) regarding child neurology training.

Psychiatric disease in an adolescent as a harbinger of cerebral X-linked adrenoleukodystrophy.

X-linked adrenoleukodystrophy (XALD) typically presents as a childhood cerebral demyelinating form, as an adult-onset adrenomyeloneuropathy or as adrenocortical insufficiency. Cerebral demyelination presenting in adolescence is unusual. We present an 17-year-old boy with adolescent-onset XALD initially manifesting with slowly progressive psychiatric symptoms.

Use of the 2010 McDonald criteria can facilitate early diagnosis of pediatric multiple sclerosis in a predominantly black cohort.

Background: Pediatric-onset multiple sclerosis represents around 3-5% of all patients with multiple sclerosis. Both the 2005 and 2010 McDonald criteria for multiple sclerosis have been suggested for the possible use in pediatric-onset multiple sclerosis. Modifications incorporated into the 2010 criteria enabled the fulfillment of dissemination in time to be met with the initial magnetic resonance imaging.

Evaluation of basal ganglia and thalamic inflammation in children with pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection and tourette syndrome: a positron emission tomographic (PET) study using 11C-[R]-PK11195.

We applied PET scanning with (11)C-[R]-PK11195 (PK) to evaluate neuroinflammatory changes in basal ganglia and thalamus in children with clinically diagnosed pediatric autoimmune neuropsychiatric disorders associated with streptococcal infection (PANDAS) and Tourette syndrome. Seventeen children with PANDAS (mean age: 11.4 ± 2.

Diffuse cerebral petechial hemorrhage in an 8-year-old girl with MRSA pneumonia and sepsis.

An 8-year-old girl in septic shock due to necrotizing methicillin-resistant Staphylococcus aureus (MRSA) pneumonia developed signs of end-organ damage, new right hemiplegia, and left gaze preference. Susceptibility-weighted MRI demonstrated extensive multifocal petechial hemorrhage preferentially at the gray-white matter interface due to septic microemboli (figure). Mechanisms of hemorrhage include small-vessel occlusion leading to mycotic aneurysm formation with rupture or pyogenic arteritis without aneurysm formation.

A behavior analysis of absolute pitch: sex, experience, and species.

Absolute pitch (AP) perception refers to the ability to identify, classify, and memorize pitches without use of an external reference pitch. In tests of AP, several species were trained to sort contiguous tones into three or eight frequency ranges, based on correlations between responding to tones in each frequency range and reinforcement. Two songbird species, zebra finches and white-throated sparrows, and a parrot species, budgerigars had highly accurate AP, they discriminated both three and eight ranges with precision.
