Hyperacute hyponatremia mimicking acute ischemic stroke: A case report.

We present a case of hyperacute hyponatremia with stroke like symptoms on presentation. Symptoms included confusion, left-sided facial droop, right-sided hemiparesis, dysarthria and aphasia, with an NIH stroke score of 5. Sodium level at the time of presentation was 119 mmol/L which dropped acutely from 138 mmol/L seven hours prior. Symptoms improved after treatment with 3% saline and no evidence of stroke, intracranial hemorrhage or space-occupying lesion was seen on imaging. The most likely cause of the hyponatremia was increased free water consumption and ADH surge. The patient remained symptom free after discharge with resolution of hyponatremia. Acute hyponatremia can cause focal neurological complaints and deficits, mimicking acute ischemic stroke. We advise clinicians to be aware of this entity when considering interventions for possible acute ischemic stroke and evaluating a patient with focal neurological deficits

Mumps: Resurgence of a once-dormant disease.

Mumps is a systemic viral illness, preventable by vaccination, that typically affects children and is characterized by unilateral or bilateral swelling of the parotid glands. Uncommon complications such as orchitis, oophoritis, deafness, pancreatitis, aseptic meningitis, and encephalitis occur more often in adults. Recent outbreaks of the disease appear to be caused by a failure to maintain herd immunity in certain populations, particularly in affluent white communities. This article reviews the clinical manifestations, diagnosis, and potential complications in patients with mumps

An unusual artery causing an unusual stroke.

Bilateral thalamic infarctions are uncommon and often lead to more severe and long-lasting symptoms than unilateral thalamic infarctions. This article describes a patient with bilateral thalamic infarction caused by occlusion in the artery of Percheron, an anatomic variant thought to be present in 4% to 12% of the population

Sex Differences in Prevalence of Emergency Department Patient Substance Use

Purpose Substance use and misuse is prevalent in emergency department (ED) populations. While the prevalence of substance use and misuse is reported, sex-specific trends in ED populations have not been documented. We set out to determine the sex-specific prevalence of ED patient substance use during this current epidemic. Methods A retrospective electronic data abstraction tool, developed for quality-improvement purposes, was used to assess ED visits in 3 hospitals in northeastern Pennsylvania. All patients with ED diagnosis codes for substance use F10.000 through F 19.999 (excluding F17 codes for nicotine) were abstracted for network ED visits at all 3 hospitals. Data points included ED clinical enrollment site, primary substance used, sex, date of ED visit, disposition (including left without being seen, left against medical advice, discharged, admitted, and treatment in rehabilitation) for 18 months (January 1, 2016 through July 31, 2017). The categorical parameters of sex, clinical enrollment site, diagnosis, date of ED visit, and disposition status were summarized as a proportion of the subject group. Time series analysis was used to assess trends in substance use and misuse visits by patient sex. Findings A total of 10,511 patients presented to the EDs during the study time period with a final diagnosis of a substance use−related reason and were included in the analysis. The mean age for these patients was 43.6 (SD 16.4) years, and the majority was male (65.6%, n = 6900). The most common substance in the final diagnosis for the ED visit was alcohol (54.3%; 95% CI, 53.3–55.2), followed by opioids (19.2%; 95% CI, 18.4–19.9) and cannabis (14.4%; 95% CI, 13.7–15.0). Females tended to be younger than males (42.4 years vs 44.3 years; P \u3c 0.001), and were more likely to be discharged after the ED visit than males (36.1% vs 32.3%; P \u3c 0.001). When exploring differences in age by sex and substance, males with a final diagnosis including alcohol- and cannabis-related issues were older than females, whereas females diagnosed with opioid-related reasons were older than males (41.3 vs 38.9 years; P \u3c 0.001). Implications There are sex-specific differences in prevalence of patients presenting with substance use in the ED setting

Brief Motivational Interviewing for Substance Use by Medical Students Is Effective in the Emergency Department.

BACKGROUND: Efficacy of medical student substance use interventions in the emergency department (ED) setting remains unstudied. OBJECTIVE: In this pilot study, we set out to determine whether medical students could perform a brief motivational interview for substance use in the ED. METHODS: At two hospitals, medical students utilized motivational interviewing skills taught by their medical school curriculum and administered a substance use intervention to ED patients who met the study definition of unhealthy substance use. RESULTS: In 6 weeks, medical students gave a brief intervention to 102 subjects. The mean age of the subjects was 46.9 (standard deviation 15.6) years. The majority, 86 (86.3%) identified as white. Fifty-four (52.9%) identified as male. Eighty of 102 (78.4%) participants completed a phone follow-up assessment. Of the 69 smokers, 11 (15.9%) reported attempting to quit or quitting completely. Of the 33 with high-risk alcohol use, 11 (33.3%) were abstaining completely from alcohol use and an additional 12 (36.4%) reported a decrease in alcohol daily consumption (measured in drinks per day). Warm hand-off success for street drugs or at-risk alcohol use was 13.6% for those who received an intervention. CONCLUSIONS: It is feasible for medical students to perform a substance use intervention in the ED setting. Medical student contributions as a part of the team response to this public health crisis provide an opportunity for further discussion and research
