Infantile ischemic stroke secondary to profound arteriopathy
JOURNAL OF THE AMERICAN COLLEGE OF EMERGENCY PHYSICIANS OPEN
2022; 3 (4): e12768
Pediatric arterial ischemic stroke (AIS) is an uncommon emergency department (ED) presentation. We share the case of a 4-month-old female with a chief complaint of irritability and difficulty feeding. During ED evaluation, she developed lateral gaze deviation, tongue deviation, and rhythmic leg movements. Computed tomography of the head revealed a right-sided hypodensity concerning for ischemic infarct without hemorrhagic conversion. Subsequent brain magnetic resonance imaging and arteriography confirmed a large right-sided cerebral infarct and demonstrated narrowing and tortuosity of almost all extra- and intracranial vessels. Comprehensive pediatric AIS workup, including echocardiogram and laboratory tests for anemia, hypercoagulability, inflammatory, and genetic panels, were non-diagnostic. This case highlights the difficulty in diagnosis of pediatric AIS due to low clinical suspicion, limited neurologic examination, and non-specific presentations that may suggest stroke mimics. Maintenance of clinical suspicion and early recognition of pediatric AIS can result in earlier initiation of neuroprotective measures and optimization of imaging strategies for better outcomes.

Pediatric Functional Neurological Disorder: Demographic and Clinical Factors Impacting Care
JOURNAL OF CHILD NEUROLOGY
This is a multicenter retrospective EMR-based chart review of 88 patients aged 3-21 years admitted for evaluation of functional neurologic disorder (FND). We sought to establish characteristics associated with FND, calculate incidence of abnormal neurodiagnostic findings, and determine features associated with variability in workup and treatment. FND patients were 65% female, 40% White, 33% Hispanic, and 88% primarily English speaking with median 13.9 years. We detected variability in management by age, ethnicity, psychiatric comorbidity, and hospital site. Our findings suggest limited utility to CTs in this setting (100% normal) and that workup can be safely informed by physical exam, which predicted abnormal MRI and LP results. We favor screening for adverse childhood experiences in FND patients. Hospitalization may be a rare opportunity for psychiatry contact.

Words Matter: An Antibias Workshop for Health Care Professionals to Reduce Stigmatizing Language.
MedEdPORTAL : the journal of teaching and learning resources
2021; 17: 11115
Introduction: Biased language influences health care providers' perceptions of patients, impacts their clinical care, and prevents vulnerable populations from seeking treatment. Training clinicians to systematically replace biased verbal and written language is an essential step to providing equitable care.Methods: We designed and implemented an interactive workshop to teach health care professionals a framework to identify and replace stigmatizing language in clinical practice. The workshop included a reflective exercise, role-play, brief didactic session, and case-based discussion. We developed the program for a broad target audience of providers and initially delivered it at three academic conferences. We used descriptive statistics to analyze Likert-style items on course evaluations and identified themes in open-text responses.Results: A total of 66 participants completed course evaluations; most believed the workshop met its objectives (4.8 out of 5.0) and strongly agreed that they would apply skills learned (4.8). Participants planned to incorporate reflection into their verbal and written language. Potential barriers to applying course content included perceived difficulty in changing entrenched practice habits, burnout, and fatigue. Suggestions for improvement included more time for group discussions and strategies to teach skills to colleagues.Discussion: Participants found the course material highly engaging and relevant to their clinical practice. Learners left the workshop feeling motivated to engage in more mindful word choice and to share key concepts with their colleagues.

Beyond the Classic VTA: Extended Amygdala Projections to DA-Striatal Paths in the Primate
2017; 42 (8): 1563–76
The central extended amygdala (CEA) has been conceptualized as a 'macrosystem' that regulates various stress-induced behaviors. Consistent with this, the CEA highly expresses corticotropin-releasing factor (CRF), an important modulator of stress responses. Stress alters goal-directed responses associated with striatal paths, including maladaptive responses such as drug seeking, social withdrawal, and compulsive behavior. CEA inputs to the midbrain dopamine (DA) system are positioned to influence striatal functions through mesolimbic DA-striatal pathways. However, the structure of this amygdala-CEA-DA neuron path to the striatum has been poorly characterized in primates. In primates, we combined neuronal tracer injections into various arms of the circuit through specific DA subpopulations to assess: (1) whether the circuit connecting amygdala, CEA, and DA cells follows CEA intrinsic organization, or a more direct topography involving bed nucleus vs central nucleus divisions; (2) CRF content of the CEA-DA path; and (3) striatal subregions specifically involved in CEA-DA-striatal loops. We found that the amygdala-CEA-DA path follows macrostructural subdivisions, with the majority of input/outputs converging in the medial central nucleus, the sublenticular extended amygdala, and the posterior lateral bed nucleus of the stria terminalis. The proportion of CRF+ outputs is >50%, and mainly targets the A10 parabrachial pigmented nucleus (PBP) and A8 (retrorubal field, RRF) neuronal subpopulations, with additional inputs to the dorsal A9 neurons. CRF-enriched CEA-DA projections are positioned to influence outputs to the 'limbic-associative' striatum, which is distinct from striatal regions targeted by DA cells lacking CEA input. We conclude that the concept of the CEA is supported on connectional grounds, and that CEA termination over the PBP and RRF neuronal populations can influence striatal circuits involved in associative learning.
