ABSTRACT
A man in his 50 s, who was found vomiting and in a disturbed state when the emergency medical team arrived, then went into cardiopulmonary arrest during transport and died without responding to resuscitation. The hospital initially suspected that the death may have been caused by internal causes, but since the deceased had previously been transported to the hospital in a suicide attempt, the hospital called police regarding suspicions of unnatural death. The police investigation revealed two empty bottles of nicotine liquid for e-cigarettes in his house and a search history of "nicotine suicide" on his cellphone. In a forensic autopsy, he was found to be highly obese, and abundant fat deposits were observed in his organs. A stent was placed in the aorta, but no abnormality was found. There was no obvious stenosis or obstruction in the coronary arteries. Drug screening using liquid chromatography tandem mass spectrometry (LC-MS/MS) was performed on cardiac blood, urine, and stomach contents collected at autopsy, which revealed the presence of some medical products such as aripiprazole, nicotine, and cotinine. Further quantitative testing revealed high concentrations of nicotine in all samples. The left and right femoral venous blood concentrations were above the lethal dose, suggesting that arrhythmia or respiratory failure due to nicotine intoxication was the cause of death. With the widespread use of e-cigarettes, high concentrations of nicotine are readily available, and case reports of serious nicotine addiction are increasing. It is important to always consider addiction when conducting forensic evaluations in the medical field.

Since one of the main characters in Three Act Tragedy was an actor, the three murders described in the book have been likened to a curtain. The three seemingly unrelated murders were connected at the end of the story, a thrill unique to the author, Agatha Christie. Nicotine was used in all three murders in this book. Nicotine is highly toxic and was one of the main pesticides used until the mid-20th century. Although its use is currently prohibited, neonicotinoid pesticides, which have reduced toxicity, are still being used. Problems with nicotine intoxication include accidental ingestion by young children, green tobacco sickness, and suicide attempts. When nicotine enters the body, it binds to acetylcholine receptors and causes various symptoms.

BACKGROUND: TikTok is a microvideo social media platform currently experiencing rapid growth and with 60% of its monthly users between the ages of 16 and 24 years. Increased exposure to e-cigarette content on social media may influence patterns of use, including the risk of overconsumption and possible nicotine poisoning, when users engage in trending challenges online. However, there is limited research assessing the characteristics of nicotine poisoning-related content posted on social media. OBJECTIVE: We aimed to assess the characteristics of content on TikTok that is associated with a popular nicotine poisoning-related hashtag. METHODS: We collected TikTok posts associated with the hashtag #nicsick, using a Python programming package (Selenium) and used an inductive coding approach to analyze video content and characteristics of interest. Videos were manually annotated to generate a codebook of the nicotine sickness-related themes. Statistical analysis was used to compare user engagement characteristics and video length in content with and without active nicotine sickness TikTok topics. RESULTS: A total of 132 TikTok videos associated with the hashtag #nicsick were manually coded, with 52.3% (69/132) identified as discussing firsthand and secondhand reports of suspected nicotine poisoning symptoms and experiences. More than one-third of nicotine poisoning-related content (26/69, 37.68%) portrayed active vaping by users, which included content with vaping behavior such as vaping tricks and overconsumption, and 43% (30/69) of recorded users self-reported experiencing nicotine sickness, poisoning, or adverse events such as vomiting following nicotine consumption. The average follower count of users posting content related to nicotine sickness was significantly higher than that for users posting content unrelated to nicotine sickness (W=2350.5, P=.03). CONCLUSIONS: TikTok users openly discuss experiences, both firsthand and secondhand, with nicotine adverse events via the #nicsick hashtag including reports of overconsumption resulting in sickness. These study results suggest that there is a need to assess the utility of digital surveillance on emerging social media platforms for vaping adverse events, particularly on sites popular among youth and young adults. As vaping product use-patterns continue to evolve, digital adverse event detection likely represents an important tool to supplement traditional methods of public health surveillance (such as poison control center prevalence numbers).

Electronic cigarettes are a popular, easily purchased, alternative source of nicotine that is considered safer than conventional tobacco. However, Intentional or accidental exposure to e-liquid substances, mainly nicotine, can lead to serious, potentially fatal toxicity. Emergency and critical care physicians should keep in mind acute intoxication of this poison with a biphasic toxic syndrome. We highlight its potentially fatal outcome and suggest monitoring the adverse effects of nicotine according to a multimodal protocol integrating somatosensory evoked potentials, electroencephalography and neuroimaging data with anamnestic report and toxicological and laboratory data.

BACKGROUND: Electronic cigarette (ECIG) use has increased dramatically in recent years. Negative ECIG-related acute health effects have included explosion/burn injuries from battery failure and child ingestion/poisoning of liquid nicotine. However, there is an urgent need for continued surveillance of ECIG health effects to determine whether these outcomes change as ECIG devices and liquids rapidly evolve. This study updates national estimates of ECIG-related emergency department (ED) visits and describes the context of these injuries. METHODS: A keyword search of case narrative text was used to identify ECIG-related ED visits in the National Electronic Injury Surveillance System (NEISS) data. These cross-sectional data are designed to be weighted to provide national estimates of consumer product-related injuries treated in EDs. ECIG-related injuries were described and categorized, and sampling weights applied to model national estimates. RESULTS: From 2015 to 2019 there were an estimated 3369 ED visits from ECIG explosion/burn injuries (95% CI = 2020, 4718), and an estimated 676 visits from 2019 alone (95% CI = 315, 1036). In 2018-2019, there were an estimated 1550 cases of children <5 years old ingesting ECIG liquids (95% CI = 778, 2322). CONCLUSIONS: Despite a notable shift in the US market towards ECIG devices that use lower electrical power and disposable "pods" (e.g., JUUL), liquid chemical ingestion among young children and ECIG explosion/burn injuries persist. Improved product regulations are urgently needed to prevent negative health effects caused by ECIGs, as well as prevent their ingestion and use by children.

E-cigarettes and heat-not-burn cigarettes (HNBC) present new health risks due to their rising popularity, high content of nicotine and serious adverse effects. The objective of the study was to analyse the cases of acute exposure to e-cigarettes, e-liquids and HNBC products containing nicotine that led to toxicological consultations at our poisons control centre during a 7-year period (2012-2018) and identify the categories of special concern that require further investigation and intervention. The demographic, toxicological and clinical data were analysed by descriptive statistics. Poisoning severity score (PSS) was estimated. From 119 229 consultations, 148 cases concerned acute exposure to e-cigarettes. Children and adolescents were exposed in 91 (61%) cases, including exposure of neonates and infants in 54 (36%) cases. The main route of exposure was ingestion in 129 (87%), inhalation in nine (6%), ocular in six (4%) and intravenous administration in three (2%) cases. The source of exposure was the cartridge with e-liquid (107; 72%), refillable tank in 29 (20%) and HNBC refill in nine (6%) cases. The reason for exposure was accidental in 110 (74%), incorrect application of the device in 10 (7%), abuse in six (4%), suicide attempt in six (4%) and other/unknown in 16 (11%) cases. The dose estimation was severe/lethal in 6 (4%), toxic in 53 (36%), low-to-moderate in 35 (24%) and unknown in 54 (36%) cases. Vomiting was observed in 38 (26%) patients; 72% of patients were hospitalised. In symptomatic cases, 41 patient had PSS 1, 12 patients had PSS 2, and one patient had PSS 3. Activated charcoal was applied in 57 (39%) patients, and symptomatic treatment was recommended in 75 (51%) patients. Cases of unintentional exposure of children demonstrate the need for preventive risk reduction measures.

This paper presents an unusual complex suicide case that died of nicotine addiction. The deceased was a 40-year-old male who was found lying dead on the floor in his room. In external findings, many incision wounds on his forearms and skin discoloration with epidermolysis on his cervical region could be seen. In the room, a blood-stained scissors and electric cord hanged on the exercise bike were found. Moreover, nine cigarette residues which were only the filter part and empty bottle of coffee were found on his side. At autopsy, we found that those injuries were not serious enough to lead him to the death. Toxicologically, caffeine, nicotine, cotinine, mirtazapine, and olanzapine could be detected, and the concentrations of nicotine were 3.740, 2.140, 3.100, and 451.100 µg/ml in cardiac blood, peripheral blood, urine, and stomach contents, respectively. These concentrations were evaluated as the fatal levels, and the cause of his death was diagnosed as acute nicotine intoxication.

Incidences of brain death due to nicotine overdose by e-cigarettes have been increasing. In such cases, liver donation has been not reported because of the secondary damage to the liver due to metabolism of large amounts of nicotine. However, kidneys have been considered acceptable for transplant. Here, we present a successful case of liver transplant from a brain-dead donor due to intentional nicotine ingestion who did not have extensive steatosis. To the best of our knowledge, this is the first report of such a case.

Introduction: Poisoning exposure cases involving e-cigarettes have increased since 2010, coinciding with increasing rates of e-cigarette use in the United States (US). Given the increasing prevalence of e-cigarette use and ever-changing product designs, particularly the development of new products with high nicotine levels, it is important to conduct ongoing surveillance of poisoning exposure cases involving e-cigarettes. The objective of this study is to describe trends and characteristics of poisoning exposure cases involving e-cigarettes and e-liquids reported to poison control centers in the US.Methods: We analyzed e-cigarette exposure cases from the National Poison Data System (NPDS) during 2010-2018 by year and other characteristics.Results: The annual number of e-cigarette exposure cases increased greatly between 2010 and 2014, reaching a peak of 3742 in 2014, and then decreasing each year between 2015 and 2017. Between 2017 and 2018, the overall number of e-cigarette exposure cases increased by 25.0% (from 2320 to 2901). Approximately two-thirds (64.8%) of all cases were in children under age five, and 14.7% were in children aged 5-17 years or young adults aged 18-24 years. A small proportion of cases developed life-threatening symptoms (0.1%); and cases with more serious medical outcomes tended to be exposed to a higher e-liquid or nicotine quantity.Conclusions: Annual declines in e-cigarette exposure cases between 2015 and 2017 did not continue in 2018. The rapid changes in the occurrence of poisoning exposure cases involving e-cigarettes coupled with the development of new tobacco products and ever-evolving tobacco use landscape underscore the importance of continued surveillance of these poisoning exposure cases. Continuous monitoring of these poisoning exposure cases may inform efforts aimed at preventing e-cigarette poisoning exposures.

We reported the first comprehensive autopsy case of death due to intravenous injection of nicotine. We examined the distribution of nicotine in the body tissues and fluid and exposed the pathophysiology of nicotine poisoning. A 19-year-old woman was rushed to the hospital in cardiorespiratory arrest and was confirmed dead upon arrival. Liquid nicotine, hydrogen peroxide water, and a syringe were found in the hotel room where she stayed. On autopsy, nicotine concentration was the highest (15,023 µg/mg) in the tissue around the injection mark on the right upper arm. Among the body fluids, the intraperitoneal fluid had the highest, whereas the pericardial fluid had the lowest (0.736 µg/mL) nicotine concentration. Among the organs, the brain had the highest (11.637 µg/mg), whereas the fat tissue had the lowest (1.307 µg/mg) nicotine concentration. The concentration of cotinine, which is the metabolite of nicotine, was the highest in the tissue around the injection mark on the right arm (5.495 µg/mg) and was almost the same among the other body fluids and organs. The respective concentrations of nicotine and cotinine were 1.529 µg/mL and 0.019 µg/mL in the left heart blood and 3.157 µg/mL and 0.002 µg/mL in right heart blood. In this case, the nicotine concentrations in blood reached the lethal level. The distributions of nicotine and cotinine, as indicated by the intravenous injection, were related to the distribution of organs that metabolize nicotine and the distribution of nicotinic acetylcholine receptors.

Pediatric sudden sensorineural hearing loss (SSNHL) is a quite rare otologic emergency. Etiology of SSNHL isn't enough clear. Electronic cigarette (EC) is a device that uses increasingly and it contain liquid which keep nicotin and various chemicals. This liquid can be ingested mistakenly by children and various side effects may develop. But hearing loss wasn't reported before as a side effect. We presented an interesting case, she was 6-year-old who developed bilaterally SSNHL associated with drinking electronic cigarette liquid.

OBJECTIVE: To describe urinary cotinine levels in tobacco farmers. METHODS: A cross-sectional study was conducted in 2,570 tobacco farmers. All participants that reported green tobacco sickness in the week prior to the interview plus a subsample of 492 pesticide applicators were included. We collected urinary samples and information about sociodemographic, behavioral, dietary, occupational characteristics, and pesticide poisoning during their lifetime. Stratification by sex and smoking was performed and the Wilcoxon and Kruskal-Wallis non-parametrical tests were used to analyze cotinine means. RESULTS: This study included 582 individuals. There was no difference in urinary cotinine means between green tobacco sickness symptomatic and asymptomatic individuals. Among non-smokers, having picked tobacco in the previous week was associated with higher cotinine means in both genders. Cotinine levels were higher on the first day of symptoms and reduced exponentially with each day in female non-smokers. Male non-smokers had higher levels on the second day and a more gradual reduction. The cotinine level rose up to 15 cigarettes/day of consumption. CONCLUSIONS: The urinary cotinine measures exposure to nicotine up to its saturation point; while green tobacco sickness, affected by tolerance, indicates nicotine poisoning. Strategies to reduce nicotine exposure in tobacco production are needed. Mechanization could be an alternative, as long as it overcame the challenge of irregular terrain and did not affect the quality of the leaf. More studies are needed to evaluate the chronic effect of nicotine exposure.

Nicotine is a dangerous substance extracted from tobacco leaves. When nicotine is absorbed in excessive amounts, it can lead to respiratory failure and cardiac arrest. The commercialization of electronic cigarettes (e-cigarettes) has allowed users to directly handle e-cigarette liquid. Consequently, the risk of liquid nicotine exposure has increased. We describe our experience of managing the case of a patient who orally ingested a high concentration of liquid nicotine from e-cigarette liquid. The patient presented with bradycardia and hypotension, which are symptoms of parasympathetic stimulation, together with impaired consciousness. He recovered following treatment with atropine and a vasopressor.
