RESUMO
Motor neuron disease is a degenerative condition involving both upper motor neurons (UMN) and lower motor neurons (LMN). While amyotrophic lateral sclerosis (ALS) is an overlap of upper and lower motor neuron involvement, primary lateral sclerosis (PLS) is predominantly an upper motor neuron involvement with lower motor involvement seen in the later stages of illness. Diagnostic criteria rely on clinical features and electrodiagnostic tests such as electromyography (EMG). EMG predominantly helps in determining lower motor neuron involvement. No definitive objective measures are currently available to determine upper motor neuron involvement. We describe a patient diagnosed with PLS based on consensus diagnostic criteria. The patient had absent LMN features both clinically and on EMG. Magnetic resonance imaging (MRI) was significant for hypointense signals in the bilateral motor strip area on susceptibility weighted sequence, suggesting a surrogate marker of degeneration involving motor neurons in the brain. Early recognition of this MRI pattern called motor band sign (MBS) can help determine the earlier diagnosis of this neurodegenerative condition, potentially translating to better treatment and outcome measures.
RESUMO
Background Modern-day studies that assess temporal trends in cardiovascular and cerebrovascular events (CCE) and outcomes among the young population in the United States (US) with depression remain limited. Methods We compared baseline demographics, comorbidities, all-cause mortality, acute myocardial infarction (AMI), percutaneous coronary interventions (PCI), arrhythmia, stroke, and venous thromboembolism (VTE) among hospitalized young adults (18-39 years) with vs. without depression using the National Inpatient Sample (NIS) from 2007 to 2014. Results A total of 3,575,275 patients out of 63,020,008 hospitalized young adults had comorbid depression (5.7%; median 31 years, 71.3% females). The depressed cohort more often comprised of older, white, male, and non-electively admitted patients. Higher rates of comorbidities, all-cause mortality, PCI, arrhythmia, VTE, and stroke were observed among the depressed cohort. The rising trend in all-cause mortality was observed among the depressed against a stable trend in the non-depressed. The prevalence of AMI remained stable among depressed with consistent upsurges in arrhythmia and stroke. Those with depression had extended hospital stay, higher hospitalization charges, and were more often transferred to other facilities or discharged against advice. Conclusions Rising trends of inpatient mortality, CCE, and higher resource utilization among young adults with depression are concerning and warrants a multidisciplinary approach to improve quality of life and outcomes.
