Objectives: Persons with injection drug use (IDU) have high healthcare utilization. Consequently, healthcare providers have opportunities to identify and treat underlying substance use disorders (SUD) that drive these hospitalizations. The study purpose was to characterize current SUD evaluation and treatment practices by primary and consulting services during hospitalization for severe infections related to IDU. Methods: This study is a retrospective chart review of inpatient admissions to an academic medical center. The 2 inclusion criteria were documentation of IDU in clinical notes and the presence of an infection likely related to IDU. Demographic and clinical data were extracted from electronic medical records. Results: A total of 108 inpatient admissions met inclusion criteria and were included in the study. The most common infections related to IDU were endocarditis (n ¼ 65, 60.2%) and osteomyelitis (n ¼ 27, 25.0%). The primary team explicitly documented substance use in the H&P and progress notes in 103 (95.4%) hospitalizations and in 84 (77.8%) at discharge. Opioid use disorder was coded by International Classification of Diseases, Ninth Revision in 62 (57.4%). The most frequent intervention was screening, brief intervention, and referral to treatment in 99 (91.7%) episodes. The vast majority of patients did not have specific plans or recommendations for SUD treatment upon discharge. Conclusions: Though more than half of the patients in this study had opioid use disorder, pharmacotherapy for opioid use disorder was typically not provided, and screening, brief intervention, and referral to treatment (SBIRT) was the most common intervention. There are significant gaps in the clinical assessment, diagnosis, and management of SUD in persons hospitalized with life-threatening complications of IDU, leaving many opportunities to improve care for this complex patient population.
Objective: To demonstrate that a known CACNA1A variant is associated with a phenotype of prolonged aphasic aura without hemiparesis. Background:The usual differential diagnosis of prolonged aphasia without hemiparesis includes vascular disease, seizure, metabolic derangements, and migraine. Genetic mutations in the CACNA1A gene can lead to a myriad of phenotypes, including familial hemiplegic migraine (FHM) type 1, an autosomal dominant disorder characterized by an aura of unilateral, sometimes prolonged weakness. Though aphasia is a common feature of migraine aura, with or without hemiparesis, aphasia without hemiparesis has not been reported with CACNA1A mutations. Methods:We report the case of a 51-year-old male who presented with a history of recurrent episodes of aphasia without hemiparesis lasting days to weeks. His headache was left sided and was heralded by what his family described as "confusion."On examination, he had global aphasia without other focal findings. Family history revealed several relatives with a history of severe headaches with neurologic deficits including aphasia and/or weakness. Imaging revealed T2 hyperintensities in the left parietal/temporal/occipital regions on MRI scan with corresponding hyperperfusion on SPECT. Genetic testing revealed a missense mutation in the CACNA1A gene.Conclusions: This case expands the phenotypic spectrum of the CACNA1A mutation and FHM to include prolonged aphasic aura without hemiparesis. Our patient's SPECT imaging demonstrated hyperperfusion in areas correlating with aura symptoms which can occur in prolonged aura.
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.
