Pseudobulbar affect (PBA) is a behavioral syndrome associated with various neurological conditions that typically manifests as uncontrollable laughing or crying. PBA can significantly impact the quality of life of patients affected as these spells can be inappropriate to the social setting or incompatible with the patient's emotional state. The underlying mechanism of PBA appears to be associated with disinhibition in neuronal pathways involving dopamine, serotonin, and glutamate, but the exact mechanism remains unclear. One hypothesis for the pathology of PBA is that it is the result of disruption of the corticopontine-cerebellar circuits, impairing cerebellar modulation of affect, and leading to uncontrolled emotional lability. Stroke, and other neurological disorders, interrupt these neuronal circuits causing disinhibition of the voluntary control of emotional expression. It is extremely important to recognize and appropriately diagnose the condition. We present a case report of an 85-year-old female patient who presented with a thalamic stroke, and she subsequently developed hypomania with symptoms of decreased need for sleep, mood lability, pressured speech, and religious preoccupation. This case discusses a unique presentation of PBA with hypomania.

Objectives: Trains can cause severe injuries in pediatric patients requiring significant resource utilization. We sought to review train injuries in Pennsylvania to determine the burden of these injuries on the pediatric trauma system.
Methods:We queried the Pennsylvania Trauma Outcomes Study Database to identify patients younger than 18 years injured by trains between 2007 and 2016. Demographics, hospital course, outcomes, and resource utilization were reviewed.Results: Thirty-five children from 17 Pennsylvania counties were included. Three counties accounted for 48.6% of injured children. The median age was 15.0 years, and most patients were White (60.0%) and male (77.1%). The median length of stay was 8.0 days and overall mortality 8.6%. Intensive care unit admission was required for 65.7%. The median Injury Severity and Functional Status at Discharge scores were 14.0 and 18.0, respectively. Major orthopedic injuries (fracture or amputation) were the most common (57.1%) followed by traumatic brain injury (45.7%), pneumothorax (14.3%), and solid organ injury (14.3%). Operative management was common with 65.7% undergoing surgery.Conclusions: Injuries caused by trains can be severe and are most commonly orthopedic or traumatic brain injuries. Targeted safety interventions may be possible given the common mechanisms and geographic clustering of these injuries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
