E-cigarette burn injuries: Comprehensive review and management guidelines proposal

Exploring General Practitioners' Knowledge, Attitudes, and Practices towards E-Cigarette Use/Vaping in Children and Adolescents: A Pilot Cross-Sectional Study in Sydney

(1) Background: The increasing use of e-cigarettes/vaping in children and adolescents has been recognised as a global health concern. We aim to explore the Knowledge, Attitude, and Practice of General Practitioners (GPs) in Sydney regarding the use of e-cigarettes in children and adolescents and identify the barriers to addressing this issue. (2) Methods: This pilot study was a cross-sectional study conducted using an electronic questionnaire with a Likert scale and free-text responses. (3) Results: Fifty-three GPs participated in the study (male = 24 and female = 29) with a mean age of 50 ± 5.5 years. There was strong agreement (mean 4.5) about respiratory adverse effects and addictive potential. However, there was less awareness of cardiac side effects and the occurrence of burns. There is a lack of conversation about e-cigarettes in GP practice and a deficit of confidence in GPs regarding managing e-cigarette use in children and adolescents. (4) Conclusions: Our pilot study has shown that GPs are somewhat knowledgeable about the potential adverse effects of the use of e-cigarettes in children and adolescents, though there is a lack of knowledge of the complete spectrum of adverse effects and more importantly, there is a paucity of a structured approach to discuss the use of e-cigarettes with children and adolescents, and there is a low level of confidence in addressing these issues. There is a need for educational interventions for GPs to increase awareness of the potential adverse effects of using e-cigarettes and build confidence in providing management to children and adolescents regarding the use of e-cigarettes.

Lithium-ion battery related burns and emerging trends: a retrospective case series and data analysis of emergency presentations

INTRODUCTION

The rising prevalence of battery powered devices is driving a steady increase in lithium-ion battery-related burns. We present a case series of patients with lithium-ion battery-related burns and describe the clinical characteristics of this cohort. To further understand emerging trends, we compare our specialty inpatient case series with emergency department (ED) data collated by the Queensland Injury Surveillance Unit (QISU).

METHODS

This is a retrospective case series of all patients admitted to the Professor Stuart Pegg Adult Burns Centre for burns relating to lithium-ion batteries between January 2014 and October 2023. In addition, we provide a retrospective data analysis of ED presentations for lithium-ion battery-related burns or blast injuries collated by the QISU.

RESULTS

Within the case series data, the most common injuries caused by lithium-ion batteries leading to burn unit admissions were due to e-scooters (57.1%). Burns relating to e-scooter batteries were more likely to involve a larger total body surface area and to be deeper in nature, than burns due to other products. The most common ED presentations were from energy storage devices such as powerpacks (43%).

CONCLUSION

Lithium-ion battery-related burns are becoming more frequent. The majority of inpatient managed cases involved burns due to larger lithium-ion batteries used in e-scooters. This is the first Australian case series describing severe burns caused by this mechanism. Primary prevention through design, technological and behavioural strategies is required.

Injuries from electronic cigarettes, and cigarette/cigar-related paraphernalia, NEISS, 2012-2022

There is a need to determine the role of smoking/vaping related products in Emergency Department (ED) product-related injuries by age and sex to determine if interventions are warranted. These products include the combustible tobacco products' paraphernalia to light them (CTPP), electronic nicotine delivery systems (ENDS), and electronic non-nicotine delivery system (ENNDS). Data from the National Electronic Injury Surveillance System (NEISS), years 2012-2022, were examined for injury data associated with CTPP and ENDS/ENNDS. Bivariate comparisons were conducted. There were an estimated 3,142 (95%CI: 2,384-3,975) ED-treated ENDS/ENNDS product-related injuries and 46,116 (95%CI: 38,712-53,520) CTPP product-related injuries. Males were more likely to have an ED-treated ENDS/ENNDS product-related injury than females (proportion 0.93 [95%CI: 0.82, 0.98] versus 0.70 [95%CI: 0.02, 0.19]) as well as a CTPP product-related injury than females (proportion, 0.60 [95%CI: 0.56, 0.64] versus 0.40 [95%CI: 0.37, 0.44]). There were more ED-treated ENDS/ENNDS product-related injuries among persons ≥18 years than <18 years (proportion, 0.89 [95%CI: 0.75, 0.96] versus 0.11 [95% CI: 0.4, 0.35]). There were also more ED-treated CTPP product injuries among persons ≥ 18 years than <18 years (proportion, 0.73 [95%CI: 0.68, 0.78] versus 0.27 [95%CI: 0.22, 0.32]). No change in the proportion of injuries in our sample associated with END/ENNDS over time were observed. There is a need to consider injuries related to ENDS/ENNDS and CTPP product-related injuries in the discussion of the risks associated with smoking/vaping. Although ENDS/ENNDS have had fewer ED-treated injuries, the number of such injuries has remained stable, rather than declined over the previous decade. Injury prevention is a public health imperative and targeted interventions by healthcare providers during routine care, and the use of public service announcements could specifically target adults ≥18 years. Providing peer-to-peer educational programs, and initiating similar programs targeted at males who use CTP and ENDS/ENNDS have the potential to decrease injury risk.

E-cigarette explosions: patient profiles, injury patterns, clinical management, and outcome

Background

E-cigarette abuse, also known as vaping, is a widespread habit. Recently, there have been increasing reports of explosions of these devices resulting in serious burn injuries, especially to the groin, hand, and face. Overheating rechargeable lithium-ion batteries are supposed to be the responsible mechanism, especially in low quality fabrications.

Methods

In this single-center retrospective study, data of 46 patients are presented and analyzed. In addition to information on demographics, injury patterns, and treatment options, this is the first study investigating outcome after an average of 13 months via a standardized telephone interview of 31 patients (67%). Patients were specifically asked regarding their outcome, vaping habits, technical modifications to their devices and supply source.

Results

Patients were mainly male (98.2%) with a median age of 36 years. Typical injury patterns included the groin region (n = 32; 69%), hands (n = 12; 25%) and face (n = 3; 7%). All patients underwent debridement, in nine cases hydrotherapeutically. 61% (n = 28) underwent consecutive tangential necrectomy and subsequent split thickness skin graft transplantation. Wound infection was observed in 18 patients (39%), with burn depth as a significant risk factor (p < 0.001). 91% of the followed-up patients were satisfied. Surprisingly, 38% were still using e-cigarettes. 42% (n = 13) reported manual modifications of their devices to prolong battery life or increasing smoke production.

Conclusions

Injuries from exploding e-cigarettes can be serious and should be treated in a specialized burn center. E-cigarette explosions lead to characteristic injury patterns and often need surgical treatment. This should be made more public to reduce their use and keep people from modifying the devices. The counterintuitive and irrational observation of a high rate of abuse even after the injury underlines their addiction potential.

Oral and Maxillofacial Injuries Associated With E-Cigarette Explosions: A Systematic Review and Management Guidelines Proposal

PURPOSE

E-cigarettes have become increasingly popular devices used to consume nicotine in recent years. There is a growing body of evidence regarding the risk of spontaneous explosion of these devices causing burn and projectile injuries. The primary purpose of this review was to summarize all injuries to the oral and maxillofacial region secondary to explosion of e-cigarettes. The secondary purpose was to propose an initial management algorithm for such injuries based on the findings in the literature. This review also aims to test the hypothesis that e-cigarette explosive injuries to the oral region were associated with an increased risk of intubation and surgery and examine whether any other injury pattern was associated with an increased risk of intubation or surgery.

METHODS

A cohort study based on identifying cases in the literature was conducted to summarize injuries to the oral and maxillofacial region and examine the associations between injury types and location and management. A literature search of the major biomedical databases was conducted in September 2022 using terms such as e-cigarette, explosion, blast, trauma, and burn, among others, which yielded 922 studies. Nonclinical studies, review articles, and studies without injuries to the facial region were excluded. Study subjects were recorded for demographics, device characteristics, injury mechanism, injury location, management, and complications. Chi-squared analysis was used to determine if the predictor variables of type of injury (burn or projectile) and its associated location (ocular, facial, or intraoral for burns and facial thirds for projectile) were associated with the outcomes of intubation and surgical management. The collected data were then used as a guide to propose an initial management algorithm for these injuries.

RESULTS

Twenty eight studies, including 20 case reports and 8 case series met the inclusion criteria. A total of 32 explosions of e-cigarettes to 32 patients caused 105 recorded injuries to the facial region. Projectile injuries made up 73.3% (n = 77) of all facial injuries, while burn injuries made up of 26.7% (n = 28). There were 14 (43.8%) patients who suffered both projectile and burn injuries. Burn injuries mostly involved the face (64.3%, n = 18), oral cavity (25%, n = 7), and eye (10.7%, n = 7). The majority (81.8%, n = 63) of projectile injuries occurred in the lower facial third. There were 20 (62.5%) patients who suffered a bone or tooth fracture. Management of injuries involved surgery in 62.5% (n = 20) of patients, which included open reduction and internal fixation of fractures, dental extraction, bone and skin grafts, and ocular surgery. A complication rate of 44.4% (n = 8) was observed across studies that reported on follow-up. There was no statistically significant association between explosive injury to the oral region and intubation or surgical management. There was also no other statistically significant association between any other injury type and location with intubation or surgical management.

CONCLUSIONS

E-cigarettes are at risk for spontaneous combustion that can cause serious oral and maxillofacial injuries, particularly to the lower facial third and commonly requiring surgical management. Safety of these devices should be improved through increased user education and regulation.

Impact of Electronic Cigarettes on the Upper Aerodigestive Tract: A Comprehensive Review for Otolaryngology Providers

Objective

The use and effects of electronic (e)-cigarettes (e-cigs) are particularly relevant for otolaryngology providers as tobacco plays a major role in benign and malignant diseases of the upper aerodigestive tract. This review aims to (1) summarize the recent policies regarding e-cigs and important patterns of use and (2) serve as a comprehensive resource for clinical providers on the known biologic and clinical effects of e-cigs on the upper aerodigestive tract.

Data Sources

PubMed/MEDLINE.

Review Methods

We conducted a narrative review on (1) general information on e-cig use and informative findings in the lower respiratory system and a comprehensive review on (2) the effects of e-cigs on cell and animal models and the clinical implications of these products on human health as is relevant to otolaryngology.

Conclusions

Although e-cigs are likely less harmful than conventional cigarettes, preliminary research on e-cigs suggest several deleterious effects including in the upper aerodigestive tract. Due to this, there has been increased interest in restricting e-cig usage, particularly among the adolescent population, and caution in recommending e-cigs to current smokers.

Implications for Practice

Chronic e-cig use is likely to have clinical implications. It is critical for otolaryngology providers to be aware of the rapidly changing regulations and use patterns regarding e-cigs and how e-cigs influence human health, particularly with regards to the upper aerodigestive tract, to accurately council patients regarding potential risks and benefits of use.

Liquid Nicotine, E-Cigarettes, and Vaping: Information for the Pediatric Emergency Medicine Provider

ABSTRACT

E-cigarettes, or electronic cigarettes, are electronic nicotine delivery systems that are marketed as a healthier alternative to tobacco cigarettes. There has been an exponential increase in their use among youth since their introduction to the United States market in 2007. With increased use and popularity, there has been an increase in calls to poison control centers regarding liquid nicotine toxicity in children and adolescents. Recent US Food and Drug Administration and other federal regulations of e-cigarettes have attempted to limit availability to youth. This article reviews trends in e-cigarette use among youth, the background and mechanism of action of e-cigarettes, liquid nicotine toxicity, management of liquid nicotine toxicity, and recent policy updates regarding e-cigarettes.

Acute injury or illness related to the inhalation of vaping aerosols among children and adolescents across Canada: A cross-sectional survey of Canadian paediatricians

Background

Vaping prevalence rates have increased among Canadian youth. Evidence suggests that vaping poses significant health risks to children and adolescents.

Objectives

The objectives of the study were to investigate epidemiological characteristics of acute injury/illness cases due to the inhalation of vaping aerosols among children and adolescents across Canada and to explore factors contributing to severe cases.

Methods

Data from the 2019 Canadian Paediatric Surveillance Program cross-sectional survey on vaping-related injury/illness were used. Analyses focused on injury/illness cases (n=71) among children and adolescents aged 0 to 17 years who presented to participating paediatricians for a harm related to the inhalation of vaping aerosols. We conducted descriptive analyses and performed logistic regression to explore associations between severe presentations requiring hospitalization or intensive care unit (ICU) admission and selected case characteristics.

Results

Of the 71 reported injury/illness cases related to inhalation of vaping aerosols, 56% of patients were male, and 68% were aged 15 to 17 years. Nicotine vaping was reported in 42% of cases, and cannabis vaping in 24%. Fifty-four per cent presented with respiratory distress, 18% with symptoms of nicotine toxicity, and 41% required hospitalization and/or admission to the ICU. Cases presenting with respiratory distress were more likely to be hospitalized/admitted to the ICU (odds ratio [OR]=5.37, 95% confidence interval [CI]:1.76 to 16.39).

Conclusions

The inhalation of vaping aerosols among children and adolescents may contribute to acute injury/illness. Clear associations between study variables and severe cases could not be established due to a small sample size. Additional research is needed to determine predictors and preventable risk factors of severe vaping-related injuries.

La protection des enfants et des adolescents contre les risques du vapotage

Le vapotage chez les jeunes comporte des risques importants pour la santé et la sécurité des enfants et des adolescents canadiens. Le présent document de principes fournit de l'information générale sur le vapotage et les produits et dispositifs qui y sont liés, traite des méfaits à court et à long terme associés à leur utilisation et propose des stratégies de prévention et d'abandon pour les jeunes vapoteurs ou ceux qui sont à risque de commencer à vapoter. Le vapotage chez les jeunes est associé à un risque accru d'usage de tabac et de substances psychoactives, de troubles de santé mentale, de pneumopathie, de cardiopathie et de blessures accidentelles. Le vapotage ne doit pas servir d'outil d'abandon du tabac chez les jeunes, en raison de son manque d'efficacité et des données probantes sur les méfaits qu'il occasionne. De nombreuses stratégies préventives et thérapeutiques utilisées pour l'abandon du tabac, y compris les stratégies comportementales et pharmacologiques, peuvent être adaptées pour aider les jeunes à arrêter de vapoter. Des recommandations sont formulées pour les intervenants communautaires et les décideurs.

Protecting children and adolescents against the risks of vaping

Youth vaping presents significant risks for the health and safety of Canadian children and adolescents. This statement provides background information about vaping, vaping products, and related devices, discusses the short- and long-term harms known to be associated with their use, and offers prevention and cessation strategies for youth who vape or are at risk for starting. Youth vaping is associated with increased risk for tobacco and other substance use, mental health problems, pulmonary and cardiovascular disease, and unintentional injuries. Vaping should not be used as a smoking cessation tool for youth, due to lack of effectiveness and evidence of harm. Many preventive and treatment strategies used for tobacco cessation, including behavioural and pharmacological options, can be adapted to help youth quit vaping. Recommendations for community stakeholders and policy makers are included.

Effects of tobacco and vaping on the skin

Cigarette and electronic cigarette use are significant public health concerns across the United States. Tobacco use remains the single most preventable cause of morbidity and mortality in the world. Electronic cigarettes initially emerged as a better alternative to conventional cigarettes and for promoting smoking cessation; however, current evidence reveals similar deleterious health implications caused by both products on almost all organ systems, including the skin. Recognition of the cutaneous manifestations associated with cigarette and electronic cigarette use is essential for dermatologists in current clinical practice. Dermatologists play a vital role in educating and counseling patients on smoking cessation. We specifically highlight the cutaneous consequences of conventional cigarette smoking and electronic cigarettes on dermatologic disease.

Maxillofacial injury related to an exploding e-cigarette

Electronic cigarettes (also known as e-cigarettes or electronic nicotine delivery systems) were invented in China in 2003 then introduced to the British market in 2007. They remain popular among the public and are deemed to be effective in reducing tobacco smoking (the UK being one of the first countries to embrace them in a harm reduction policy). However, reports in the media of e-cigarettes exploding are of concern, considering the potential functional and psychological impairment that lifelong disfigurement will cause, especially given their uptake among people of any age. We present a case of this rare, but dramatic, effect of e-cigarette use as a warning to the public.

Growing pains: An overview of cannabis quality control and quality assurance in Canada

In the past decade, the predominant prohibition model for cannabis use has shifted towards a regulated legal model, most widely in the context of medical purposes. In 2018, Canada became the first G7 country to legalize cannabis for adult use, implementing a two-phase roll-out of cannabis regulations. A stated goal of the new legal framework is to minimize harms by providing a safe supply of cannabis to Canadian consumers. One way that this can be achieved is through appropriate Quality Control and Quality Assurance (QC/QA) measures. Canada has implemented stringent QC/QA measures for all classes of cannabis, which include requirements such as labelling THC and CBD content per product and limiting THC doses. This paper will provide an overview of the current QC/QA measures in Canada, highlighting differences based on class of cannabis and consider the strengths and weaknesses of the current standards. QC/QA standards represent a key safety feature that can enable informed purchasing and provide consumers with necessary information about various cannabis products. As Canada continues to progress its cannabis policies, QC/QA measures provide a key consideration for ensuring Canada meets its objective of providing a safe supply of cannabis to Canadian consumers.

Injuries associated with electronic nicotine delivery systems: A systematic review

BACKGROUND

Since its introduction on the market in 2007, the number of reports on injuries caused by the overheating, ignition, or explosion of electronic nicotine delivery systems (ENDSs) has increased significantly. These injuries appear to have different causes, the most important one being lithium-ion battery overheating to the point of ignition or explosion.

METHODS

A literature search for all relevant studies concerning ENDS-related traumatic injuries of all kinds was conducted, according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses protocol. The search started with the first introduction of ENDSs in 2007 and ended February 2020. Articles included were reports on patients who sustained flame, chemical, or traumatic injuries of the skin, soft tissue, and/or bone, related to the use of ENDSs.

RESULTS

This systematic review includes 180 patients from 41 case series and reports, published between 2016 and 2020. The mean age was 30.8 years (range, 17-59 years) with an overall male predominance (168 of 180 patients, 93%). In most injuries, multiple anatomical sites were affected, with the thigh/lower limb being the most commonly injured area (77%) followed by the upper limb/hand (43%). Eighty-two patients (51%) required a surgical treatment, 70 patients (43%) were managed conservatively with dressings or ointments, and 9 patients (6%) underwent enzymatic debridement. Thirty-five percent of all patients underwent skin grafting.

CONCLUSION

Injuries from overheating, ignition, or explosion of ENDSs are an emerging, underreported, and underresearched issue. There is a need for increased regulation of ENDSs and improved surveillance of related injuries. Both health care providers and consumers should be made aware of the risks and be advised about how to safely handle these devices. In contrast to other articles, this systematic review includes all types of injuries related to ENDS overheating, ignition, and explosion. To our knowledge, this is the most extensive systematic review performed to date.

Umbilical cord-derived mesenchymal stem cells preconditioned with isorhamnetin: potential therapy for burn wounds

BACKGROUND

Impaired wound healing can be associated with different pathological states. Burn wounds are the most common and detrimental injuries and remain a major health issue worldwide. Mesenchymal stem cells (MSCs) possess the ability to regenerate tissues by secreting factors involved in promoting cell migration, proliferation and differentiation, while suppressing immune reactions. Preconditioning of MSCs with small molecules having cytoprotective properties can enhance the potential of these cells for their use in cell-based therapeutics.

AIM

To enhance the therapeutic potential of MSCs by preconditioning them with isorhamnetin for second degree burn wounds in rats.

METHODS

Human umbilical cord MSCs (hU-MSCs) were isolated and characterized by surface markers, CD105, vimentin and CD90. For preconditioning, hU-MSCs were treated with isorhamnetin after selection of the optimized concentration (5 µmol/L) by cytotoxicity analysis. The migration potential of these MSCs was analyzed by the in vitro scratch assay. The healing potential of normal, and preconditioned hU-MSCs was compared by transplanting these MSCs in a rat model of a second degree burn wound. Normal, and preconditioned MSCs (IH + MSCs) were transplanted after 72 h of burn injury and observed for 2 wk. Histological and gene expression analyses were performed on day 7 and 14 after cell transplantation to determine complete wound healing.

RESULTS

The scratch assay analysis showed a significant reduction in the scratch area in the case of IH + MSCs compared to the normal untreated MSCs at 24 h, while complete closure of the scratch area was observed at 48 h. Histological analysis showed reduced inflammation, completely remodeled epidermis and dermis without scar formation and regeneration of hair follicles in the group that received IH + MSCs. Gene expression analysis was time dependent and more pronounced in the case of IH + MSCs. Interleukin (IL)-1β, IL-6 and Bcl-2 associated X genes showed significant downregulation, while transforming growth factor β, vascular endothelial growth factor, Bcl-2 and matrix metallopeptidase 9 showed significant upregulation compared to the burn wound, showing increased angiogenesis and reduced inflammation and apoptosis.

CONCLUSION

Preconditioning of hU-MSCs with isorhamnetin decreases wound progression by reducing inflammation, and improving tissue architecture and wound healing. The study outcome is expected to lead to an improved cell-based therapeutic approach for burn wounds.

[Where there´s smoke - there´s no fire? - Burns from E-Cigarette explosions]

INTRODUCTION

The popularity of E-Cigarettes is increasing. Besides addiction and pulmonary health damage, reports of burn injuries from e-cigarette explosions are also increasing. Mostly, explosions of e-cigarettes are attributed to its lithium-ion battery. Due to increasing cases and missing guidelines we want to present three cases of our hospital and publish recommendations for the management of burn injuries caused by e-cigarette explosions.

PATIENTS/MATERIAL AND METHODS

Three cases of e-cigarette explosions which occurred between 2016 and 2019, are presented.

RESULTS

All three e-cigarette explosions occurred in the trouser pockets. Two patients were male one patient was female. The age ranged from 24 to 64 years, the burned total body surface area (TBSA) from 3 % to 12.5 %. All three patients required skin grafting and the length of stay in hospital ranged from five to eleven days.

CONCLUSION

In the synopsis of recent literature, we recommend the following management of burns due to e-cigarette explosions. The guidelines of the Advanced Trauma Life Support should be followed, signs of an inhalation trauma should be checked and litmus test should be performed prior to irrigation with aqueous solutions to prevent exothermic reactions with remaining metals. If litmus test shows alkali pH wounds should be irrigated by mineral oil.

Perceptions and Use of Electronic Nicotine Delivery Systems Among Floridian Middle and High School Students: Secondary Analysis of Cross-sectional Survey Results

Introduction:

Rapid increase in youth use of Electronic Nicotine Delivery Systems (ENDS) led the state and the federal governments to implement minimum-age policies to restrict minors’ access to vaping products. Limited success of the age restrictions fueled efforts to increase the distribution age of all tobacco products to 21 (ie, Tobacco 21 or T21 policies). With limited data on the T21 policies, the current study examines the prevalence of ENDS use and the perceptions about ENDS among youth in the pre- and post-policy-implementation periods for one of these bans in the state of Florida.

Methods:

This study conducted secondary analysis on the responses from the 2014 and 2015 Florida Youth Tobacco Survey, which collected cross-sectional data.

Results:

Compared to the data from spring of 2014, the minimum-age policy enacted on July 1, 2014 did not lead to a significant decrease in Florida’s high school and middle school students’ ever ENDS use (14.9% in 2014 vs 25.8% in 2015) and current ENDS use (7.5% in 2014 vs 12.4% in 2015). There was some ambiguity among students regarding the ENDS harm—more students in 2015 thought of ENDS as both equally (11.0% vs 7.7%) and less (32.4% vs 28%) harmful than cigarettes. There was a decrease in the proportion of students who were unsure about their answer to this question (51.5% vs 59.2%).

Conclusions:

Policy change alone may not be effective in shifting the trend of ENDS use among middle and high school students. Although students may know about some of the ENDS effects, many of them are still not aware about the harms. Interventions in school and in the community should be aiming to raise this awareness.

Combustible and electronic cigarette use among patients at a large academic dental school clinic: A preimplementation needs assessment survey

BACKGROUND

Tobacco product use is a significant public health concern, particularly with the increasing use of electronic nicotine delivery systems (electronic cigarettes [e-cigarettes]). Dental care providers are well positioned to screen and provide guidance regarding tobacco use, but these services are generally underused.

METHODS

In preparation for a quality improvement project, patients at a large academic dental school clinic were anonymously surveyed regarding past and current use of combustible cigarettes and e-cigarettes, attitudes about quitting, and health beliefs regarding these products.

RESULTS

Among 166 surveyed patients, past month use of combustible cigarettes, e-cigarettes, and both combustible cigarettes and e-cigarettes (dual use) was reported by 14.5%, 2.4%, and 5.4% of patients, respectively. Daily combustible cigarette, e-cigarette, and dual use was reported by 12.7%, 1.2%, and 1.8% of patients, respectively. Most current tobacco users expressed thoughts or plans about changing their tobacco use and concerns regarding continued use of these products on their oral health. More than one-half of the current tobacco users expressed interest in receiving additional support to help them quit.

CONCLUSIONS

Dental care providers see a sizable number of patients who use combustible cigarettes and e-cigarettes, many of whom are concerned about the potential harms of these products on their health and express interest in tobacco-use cessation support.

PRACTICAL IMPLICATIONS

It is critical that dental care professionals engage in efforts to assess combustible cigarette and e-cigarette use and provide guidance regarding these products to their patients.

Review of Health Consequences of Electronic Cigarettes and the Outbreak of Electronic Cigarette, or Vaping, Product Use-Associated Lung Injury

Electronic cigarettes (e-cigarettes) are battery-operated devices to insufflate nicotine or other psychoactive e-liquid aerosols. Despite initial claims of e-cigarettes as a nicotine-cessation device, aggressive marketing of e-cigarettes has led to an explosion in adolescents' and young adults' use over the last few years. Coupled with a lack of adequate investigation and regulation of e-cigarettes, the USA is facing an outbreak of e-cigarette, or vaping, product use-associated lung injury (EVALI) starting in mid-2019. While little long-term health hazard data are available, the components and constituents of e-cigarettes may adversely impact health. Propylene glycol and glycerin are humectants (water-retaining excipients) that generate pulmonary irritants and carcinogenic carbonyl compounds (e.g., formaldehyde, acetaldehyde, and acrolein) when heated in e-cigarettes. Metals contained in heating coils and cartridge casings may leach metals such as aluminum, chromium, iron, lead, manganese, nickel, and tin. Flavoring agents are considered safe for ingestion but lack safety data for inhalational exposures. Diacetyl, a common buttery flavoring agent, has known pulmonary toxicity with inhalational exposures leading to bronchiolitis obliterans. In 2019, clusters of lung injury associated with e-cigarette use were identified in Wisconsin and Illinois. Patients with EVALI present with a constellation of respiratory, gastrointestinal, and constitutional symptoms. Radiographically, patients have bilateral ground glass opacifications. As of February 18, 2020, the Centers for Disease Control has identified 2807 hospitalized patients diagnosed with either "confirmed" or "probable" EVALI in the US. Currently, vitamin E acetate (VEA) used as a diluent in tetrahydrocannabinol vape cartridges is implicated in EVALI. VEA cuts tetrahydrocannabinol oil without changing the appearance or viscosity. When inhaled, pulmonary tissue lacks the mechanism to metabolize and absorb VEA, which may lead to its accumulation. While most EVALI patients were hospitalized, treatment remains largely supportive, and use of corticosteroids has been associated with clinical improvement. The outbreak of EVALI highlights the need for regulation of e-cigarette devices and e-liquids. Clinicians need to be aware of the health hazards of e-cigarettes and be vigilant in asking about vaping.

Projectile Wound to Head from Modified Electronic Cigarette Explosion

One of the dangers of a rapidly growing technology industry is the risk involved in being intimately close to lithium-ion batteries. When exposed to improper conditions, lithium-ion batteries in a variety of devices have been reported to ignite and, in some cases, explode. With the rise of electronic cigarette use and modifications, the lithium-ion batteries in these devices are subject to a higher risk of malfunction. This is a retrograde analysis of a 38-year-old man who experienced fatal penetrating head trauma while using a modified electronic cigarette device. The findings suggest that the trauma from the explosion was caused by the thermal runaway of the lithium-ion battery in the modified e-cigarette.

Oral erosions associated with surreptitious marijuana vaping in an adolescent boy

A 15-year-old boy presented with painful ulcerations affecting the oral mucosa that were eventually attributed to marijuana vaping. In this case report, we highlight cannabis vaping as a potential cause of oral erosions due to injury and chronic inflammation of the oral mucosa.

[Volcano in the Pocket: Danger Induced by Electronic Cigarettes]

Volcano in the Pocket: Danger Induced by Electronic Cigarettes Abstract. We report two cases of male patients with deep second-degree burns at the lower extremities after thermal runaway of lithium-ion-batteries, which were carried in their trouser pockets as spare batteries for their electronic cigarettes. Both patients were treated according to the official burns guidelines. Here we would like to focus on the fact that irrigation with water is not recommended as the initial treatment for chemical burns caused by lithium. Currently this is not mentioned in the official burns guidelines.
