Nicotine Toxicity From Repeat Use of Nicotine Pouches.

BACKGROUND: Nicotine pouches have emerged as a novel way to administer concentrated nicotine and come as a white powder in flavored, microfiber pouches placed between the cheek and gums to dissolve without requiring spitting. While marketed as a safe alternative to smoking, nicotine pouches have the potential for toxic exposure to users. CASE PRESENTATION: We present a case of a 21-year-old male with acute nicotine toxicity through repeated administration of nicotine pouches. Over the course of 12 hours, he consumed 15 extra-strength nicotine pouches (10.9 mg per pouch) as a study tool to prepare for the next-day exams. He presented to the emergency department with bizarre behavior requiring admission for persistent confusion and nausea which resolved after 24 hours. CONCLUSIONS: This case represents the first case of acute nicotine toxicity secondary to nicotine pouch use. These pouches are emerging as a novel way to use nicotine and present a serious risk of inadvertent overdose and harm. IMPLICATIONS: Nicotine pouches are emerging as a novel way to use nicotine, and second to e-cigarettes, are the most frequently used nicotine product among youth. These pouches, which lack clear warning labels, are promoted among social media forums and present a serious risk of inadvertent overdose and harm, especially among young adults. Healthcare professionals should be aware of this risk, especially from acute, repeated exposures, and should ensure the public is cautioned appropriately.

Barriers and facilitators to the implementation of rapid HIV testing in Canadian Emergency Departments: a mixed methods study.

OBJECTIVES: 1 in 7 Canadians with Human Immunodeficiency Virus (HIV) do not know their status. Patients at increased risk of HIV routinely access the emergency department (ED), yet few are tested, representing a missed opportunity for diagnosis and linkage-to-care. Rapid HIV testing provides reliable results within the same ED encounter but is not routinely implemented. The objective of this study was to identify barriers and facilitators to rapid HIV testing in Ontario EDs. METHODS: We employed a mixed-methods, convergent, parallel design study including online surveys and semi-structured interviews of physicians, nurses, and allied health across four hospitals in Toronto and Thunder Bay, Ontario. Data were analyzed in equal priority using descriptive statistics for quantitative data and thematic analysis for qualitative data guided by the Theoretical Domains framework and Capability, Opportunity, Motivation Behaviour change model. RESULTS: Among 187 survey respondents, 150 (80%) felt implementing rapid HIV testing would be helpful in the ED. Facilitators included availability of resources to link patients to care after testing (71%), testing early in patient encounters (41%), and having dedicated staff with lived experience support testing (34%). Motivation to offer testing included opportunities to support an underserved population (66%). Challenges to implementation included limited time during ED patient encounters (51%) and a lack of knowledge around HIV testing (42%) including stigma. Interview themes confirmed education, and integration of people with lived experience being essential to provide rapid HIV testing and linkage-to-care in the ED. CONCLUSIONS: Implementation of rapid HIV testing in the ED is perceived to be important irrespective of practice location or profession. Intrinsic motivations to support underserved populations and providing linkage-to-care are novel insights to facilitate testing in the ED. Streamlined implementation, including clear testing guidelines and improved access to follow-up care, is felt to be necessary for implementation.

ABSTRAIT: OBJECTIFS: 1 Canadien sur 7 atteint du virus de l'immunodéficience humaine (VIH) ne connaît pas son statut. Les patients présentant un risque accru de contracter le VIH ont régulièrement accès au service des urgences (SU), mais peu d'entre eux sont testés, ce qui représente une occasion manquée de diagnostic et de lien avec les soins. Le dépistage rapide du VIH fournit des résultats fiables dans la même situation d'urgence, mais n'est pas systématiquement mis en œuvre. L'objectif de cette étude était d'identifier les obstacles et les facilitateurs au dépistage rapide du VIH dans les urgences de l'Ontario. MéTHODES: Nous avons utilisé une étude de conception mixte, convergente et parallèle, y compris des sondages en ligne et des entrevues semi-structurées auprès de médecins, d'infirmières et d'auxiliaires de la santé dans quatre hôpitaux de Toronto et de Thunder Bay, en Ontario. Les données ont été analysées en priorité égale à l'aide de statistiques descriptives pour les données quantitatives et d'analyses thématiques pour les données qualitatives guidées par le cadre des domaines théoriques et le modèle de changement de capacité, d'opportunité et de motivation. RéSULTATS: Parmi 187 répondants au sondage, 150 (80 %) étaient d'avis que la mise en œuvre d'un dépistage rapide du VIH serait utile à l'urgence. Les facilitateurs comprenaient la disponibilité de ressources pour lier les patients aux soins après le test (71 %), le dépistage précoce lors des rencontres avec les patients (41 %) et la présence d'un personnel dévoué avec des tests de soutien de l'expérience vécue (34 %). La motivation à offrir des tests comprenait des occasions de soutenir une population mal desservie (66 %). Les difficultés de mise en œuvre comprenaient un temps limité pendant les rencontres avec les patients aux urgences (51 %) et un manque de connaissances sur le dépistage du VIH (42 %), y compris la stigmatisation. Les thèmes des entrevues ont confirmé que l'éducation et l'intégration des personnes ayant une expérience vécue sont essentielles pour fournir un dépistage rapide du VIH et un lien avec les soins aux urgences. CONCLUSIONS: La mise en œuvre du dépistage rapide du VIH aux urgences est perçue comme importante, quel que soit le lieu de pratique ou la profession. Les motivations intrinsèques à soutenir les populations mal desservies et à fournir un lien avec les soins sont de nouvelles idées pour faciliter les tests à l'urgence. Une mise en œuvre simplifiée, y compris des lignes directrices claires sur les tests et un meilleur accès aux soins de suivi, est jugée nécessaire pour la mise en œuvre.

Initiation of opioid agonist therapy after hospital visits for opioid poisonings in Ontario.

BACKGROUND: Emergency department visits and hospital admissions for opioid toxicity are opportunities to initiate opioid agonist therapy (OAT), which reduces morbidity and mortality in patients with opioid use disorder (OUD). The study objectives were to evaluate OAT initiation rates after a hospital encounter for opioid toxicity in Ontario, Canada, and determine whether publication of a 2018 Canadian OUD management guideline was associated with increased initiation. METHODS: We conducted a retrospective, population-based serial cross-sectional study of hospital encounters for opioid toxicity among patients with OUD between Jan. 1, 2013, and Mar. 31, 2020, in Ontario, Canada. The primary outcome was OAT initiation (methadone, buprenorphine-naloxone, or slow-release oral morphine) within 7 days of discharge, measured quarterly. We examined the impact of the release of the OUD management guideline on OAT initiation rates using Autoregressive Integrated Moving Average models. RESULTS: Among 20 702 hospital visits for opioid toxicity among patients with OUD, the median age was 35 years, and 65.1% were male. Over the study period, the percentage of visits leading to OAT initiation within 7 days rose from 1.7% or less (Q1 2013) to 5.6% (Q1 2020); however, the publication of the Canadian OUD management guideline was not associated with a significant increase in these rates (0.14% slope change, 95% confidence interval -0.11% to 0.38%; p = 0.3). INTERPRETATION: Among hospital encounters for opioid toxicity, despite rising prevalence over time, only 1 in 18 patients were dispensed OAT within a week of discharge in early 2020. These findings highlight missed opportunities to initiate therapies proven to reduce mortality in patients with OUD.

A visually striking case of primary acrocyanosis: A rare cause of the blue digit.

Cold environments can trigger a variety of conditions, which, in their acute phase often present to the Emergency Department. Primary acrocyanosis is a distinct, rare condition which may be missed resulting in misdiagnosis and mismanagement. Primary acrocyanosis is a peripheral vascular disorder defined by painless, symmetrical discoloration of the distal appendages and uniquely characterized by persistence of the skin color changes after cold exposure. We present a case of a 24-year-old female who presented to the Emergency Department with peripheral cyanosis after cold exposure and was eventually diagnosed with primary acrocyanosis by Rheumatology. The prognosis for primary acrocyanosis is quite good in comparison to other acrosyndromes and once secondary causes of acrocyanosis have been ruled, out can be managed conservatively with lifestyle modifications and potential follow-up with Rheumatology.
