Abstract
Background The objective of the study was to assess the demographics, clinical parameters, and outcome of acute intoxications among adult patients admitted to a medical intensive care unit in southern Croatia. Materials and Methods An observational retrospective study was conducted over a 1-year period. The subjects were patients admitted to the intensive care unit for acute poisoning. Results In all, 81 subjects (32.1% females) aged 43.16 ± 14.77 years were admitted to the intensive care unit because of poisoning (14.97% of the total annual intensive care unit admissions). Psychiatric disorders were previously established in 76.5% participants, and 69.1% of all acute intoxications were classified as suicidal. Non-suicidal subjects differed from suicidal subjects in age (37.36 ± 9.71 vs. 45.75 ± 15.93 years; P = 0.009), in pCO2 (6.38 ± 1.78 vs. 5.50 ± 1.26 kPa; P = 0.020), in length-of-stay in intensive care unit (median 1.00, interquartile range 1.00 vs. median 2.00, interquartile range 2.00 days; P = 0.022), and in length-of-stay in hospital (median 2.00, interquartile range 2.00 vs. median 10.50, interquartile range 15.25 days; P < 0.001). Three (3.7%) patients died. Pharmaceutical psychoactive drug intoxications were the most common poisoning cases; of these, diazepam was the most frequent (16.8%), followed by ethanol (9.0%) and alprazolam (7.8%). Benzodiazepines/hypnotics were the most common group (28.7%), followed by antipsychotics (13.2%). Intoxications with more than 1 poison accounted for the largest number of cases (67.9%). The number of toxins was significantly correlated with length-of-stay in the hospital (rho = -0.265; P = 0.008), systolic blood pressure (rho = -0.318; P = 0.002), and diastolic blood pressure (rho = -0.262; P = 0.009). The electrocardiogram was considered abnormal in 50.62% of the cases. Conclusion Acute intoxicants were most commonly caused by psychiatric pharmaceutical drugs. Multidrug exposure was a typical pattern of acute intoxication.

Abstract
PURPOSE This systematic review summarizes and presents the current state of research quantifying the relationship between mental disorder and overdose for people who use opioids. METHODS The protocol was published in Open Science Framework. We used the PECOS framework to frame the review question. Studies published between January 1, 2000, and January 4, 2021, from North America, Europe, the United Kingdom, Australia, and New Zealand were systematically identified and screened through searching electronic databases, citations, and by contacting experts. Risk of bias assessments were performed. Data were synthesized using the lumping technique. RESULTS Overall, 6512 records were screened and 38 were selected for inclusion. 37 of the 38 studies included in this review show a connection between at least one aspect of mental disorder and opioid overdose. The largest body of evidence exists for internalizing disorders generally and mood disorders specifically, followed by anxiety disorders, although there is also moderate evidence to support the relationship between thought disorders (e.g., schizophrenia, bipolar disorder) and opioid overdose. Moderate evidence also was found for the association between any disorder and overdose. CONCLUSION Nearly all reviewed studies found a connection between mental disorder and overdose, and the evidence suggests that having mental disorder is associated with experiencing fatal and non-fatal opioid overdose, but causal direction remains unclear.

An analysis of 1344 consecutive acute intoxication cases admitted to an academic emergency medicine department in Turkey. North Clin Istanb 2021; 8:377-384. [PMID: 34585073 PMCID: PMC8430352 DOI: 10.14744/nci.2020.98957] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2019] [Accepted: 12/25/2020] [Indexed: 12/05/2022] Open
Abstract
OBJECTIVE: One of the major causes of emergency department (ED) visits is acute poisoning. Acute intoxications occur soon after either single or multiple exposures to toxic substances, and they started to be a more serious problem in developing countries. The objective of this study was to investigate the local patterns of acute intoxications, as well as clinical and sociodemographic characteristics of patients with acute poisoning, admitted to our hospital’s ED. METHODS: This single-center, retrospective study was conducted using medical records of consecutive patients admitted to the ED between January 2016 and December 2017. RESULTS: A total of 1344 patients were included in the statistical analysis. Of these, 673 (50.1%) were female. Mean (±SD) age was 32.2 (±12.0), ranging between 17 and 84 years. The highest number of poisoning cases was observed in summer, especially in July (10.0%) and August (11.8%), whereas lowest number of admissions related to poisoning occurred during winter in November (5.1%) and December (5.2%). Among admitted cases, many were suicide attempts (55.7%) followed by non-intentional (accidental) ingestion of non-pharmaceutical (n=553, 41.2%) and pharmaceutical agents (n=42, 3.1%). Single agents were the most common cause of acute intoxications (63.2%) rather than multidrug intoxications. Most frequently observed causes of poisonings were recreational substances (30.0%) and agents exposed by inhalation (13.2%). INR, lactate, and pH levels at admission were significant predictors of 7-day mortality without a significant paired difference between each other. The AUCs for each were 0.89 (SE 0.04; p<0.0001), 0.84 (SE 0.10; p=0.0007), and 0.79 (SE 0.11; p=0.0102), respectively. CONCLUSION: We conclude that recreational substances and medicinal drug intoxications were the leading cause of acute poisonings in our region, occurring mostly during the summer.

Abstract
IMPORTANCE Previous studies have suggested that patients with cancer may be at an increased risk of death from unintentional injury, but to our knowledge, no large studies have examined the rates of death from unintentional injury among patients with cancer. OBJECTIVE To characterize the incidence of death from unintentional injury among patients with cancer in the United States. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study included patients diagnosed with a first primary cancer between January 1, 1973, and December 31, 2015, identified from the Surveillance, Epidemiology, and End Results (SEER) program data. Comparisons with the general US population were based on mortality data collected by the National Center for Health Statistics. Analyses were performed from February 1, 2019, to August 15, 2019. MAIN OUTCOMES AND MEASURES Rates and standardized mortality ratios (SMRs) of death from unintentional injury among patients with cancer. RESULTS A total of 8 271 020 patients with cancer were included in this study (50.2% female; mean [SD] age, 63.0 [15.7] years). Among them, 40 599 deaths from unintentional injury were identified. The rates of death from unintentional injury were 81.90 per 100 000 person-years among patients with cancer and 51.21 per 100 000 person-years in the corresponding US general population. The SMR of death from unintentional injury was 1.60 (95% CI, 1.58-1.61). Higher rates of death from unintentional injury were associated with increasing age at diagnosis (≥80 years; rate ratio [RR], 2.91; 95% CI, 2.84-2.98; P < .001), male sex (RR, 1.69; 95% CI, 1.66-1.73; P < .001), American Indian or Alaskan Native population (RR, 1.48; 95% CI, 1.30-1.68; P < .001), and being unmarried (RR, 1.23; 95% CI, 1.18-1.28; P < .001). Rates of death from unintentional injury were the highest in patients with cancers of the liver (200.37 per 100 000 person-years), brain (175.04 per 100 000 person-years), larynx (148.78 per 100 000 person-years), and esophagus (144.98 per 100 000 person-years). The SMRs were the highest in the first month after cancer diagnosis. CONCLUSIONS AND RELEVANCE This study found that the incidence of death from unintentional injury among patients with cancer was significantly higher than that in the general population in the United States. The rates of death from unintentional injury varied by age, sex, race/ethnicity, marital status, cancer site, disease stage, and time since diagnosis. The findings suggest that death from unintentional injury among patients with cancer requires further attention and that initiatives to identify patients at risk and to develop targeted prevention strategies should be prioritized.

Abstract
Background: Poisoning is a leading cause of injury-related death in the United States. The Toxicology Investigators Consortium (ToxIC) Case Registry, established by the American College of Medical Toxicology, prospectively captures patients who were directly cared for and managed at the bedside by medical toxicology services. We sought to describe exposure cases who presented to Emergency Departments (EDs) across ToxIC sites, received direct bedside care by medical toxicologists; however, the intoxication resulted in fatality.Methods: We identified all cases in the ToxIC Case Registry that resulted in fatality after hospital presentation over the 6-year study period. We collected data on patient demographics and clinical information including age group, sex, circumstances of exposure, route of exposure, substances involved, presenting signs and symptoms and management prior to death.Results: Of 44,567 recorded cases in the registry over the study period, 268 (0.6%) fatalities met the inclusion criteria and comprise the study cohort. There was no sex predominance (138 females; 51.5%) and 27 (10.1%) were pediatric fatalities. In 195 (72.7%) patients, exposure was intentional. In 175 (65.3%) patients, fatality was associated with exposure to pharmaceuticals. The leading substances resulting in death were non-opioid analgesics, followed by opioids (72% prescription opioids), cardiovascular medications, sedatives, antipsychotics, antidepressants, and sympathomimetics. At time of consult, the central nervous system was the most common system affected in both fatal and non-fatal cases. Compared with non-fatal ToxIC cases (n = 44,299), fatal cases involved significantly less children (27.7% vs. 10.1%, respectively; p < .001), and were managed more aggressively (e.g., mechanical ventilation 8.3% vs. 69.8%, p < .001). Both non-opioid analgesics (25.3% vs. 14.7%; p < .001) and opioids (17.8% vs. 7.5%; p < .001) were significantly more likely to be ingested in fatal compared with non-fatal cases, although analgesics, opioids, and non-opioids, were the most common agents implicated in both groups.Conclusions: Most ToxIC registry exposures resulting in death involve intentional exposure, without sex predominance. One in 10 fatalities involved a child. Analgesics, non-opioids, and opioids are the most commonly implicated agents in both fatal and non-fatal intoxications, which highlights the centrality of these agents as major sources of both morbidity and mortality.

Abstract
Background Poisoning with methadone is considered dangerous and fatal, which can lead to decreased consciousness, coma, apnea and eventually death. Aims The present study was conducted to evaluate the effect of educating the clients of rehabilitation (rehab) centers on the frequency of methadone poisoning among children. Methods In the present semi-experimental study, the study population included all of the clients referred to the rehab centers in an urban area of Iran who received treatment with methadone. Samples were selected using the census method. The data gathering tool was a researcher-made questionnaire of which the content validity has been approved. To perform the educational program, educational brochures were distributed among all the rehab centers (33 centers) and one face-to-face educational session was conducted at each center. Six months after the intervention, the number of under 12 year-old children who were referred to hospital with methadone poisoning was calculated and compared to the same number from the 6 months prior to the study. Data were analyzed using SPSS 18. Results According to the results, the number of methadone poisonings during the 6-month period prior to the study was 29, while the same number during the 6-month period after the intervention was 9. Fisher's exact test showed a significant difference between the number of methadone poisonings before and after the intervention (p < 0.001). Conclusion The increased level of knowledge among the parents referred to rehab centers could decrease the rate of poisoning among their children. Therefore, performing this educational program is recommended for all the rehab centers.

Abstract
BACKGROUND Acute poisoning is a common chief complaint leading to emergency department visits and hospital admissions in developing countries such as Iran. Data describing the epidemiology of different poisonings, characteristics of the clinical presentations, and the predictors of outcome are lacking. Such data can help develop more efficient preventative and management strategies to decrease morbidity and mortality related to these poisonings. This manuscript describes the epidemiology of acute poisoning among patients admitted to the intensive care unit (ICU) in Birjand, Iran. METHODS This retrospective, cross-sectional study was conducted to characterize acute poisonings managed in the ICU during a 7-year period from March 2010 to March 2017 in a single center in Birjand, Iran. Patient characteristics, suspected exposure, the route of exposure, and outcome data were collected from hospital medical records. RESULTS During the study period, 267 (64% male and 36% female) patients met inclusion criteria. Pharmaceutical medication (36.6%), opioids (26.2%) followed by pesticides (13.9%) were the most common exposures 38.2% of these cases were identified as suicide attempts. There were different frequencies in terms of xenobiotic exposure in relation to gender (p = 0.04) and the survival (p = 0.001). There was a significant difference between various xenobiotics identified as the cause of poisoning (p = 0.001). Mortality rate in our study was 19.5%. The incidence of outcomes was significantly higher in patients poisoned with opioids, pesticides, benzodiazepines, and tricyclic antidepressants (p < 0.05). The median length of hospital stay was higher in pesticide-poisoned patients (p = 0.04). CONCLUSION Opioids and pesticides were the most common exposures. The mortality rate of the poisoned patients in the ICU was proportionately high. The mortality rate due to opioid poisoning is a major concern and the most significant cause death due to poisoning in the region. Further monitoring and characterization of acute poisoning in Birjand, Iran is needed. These data can help develop educational and preventative programs to reduce these exposures and improve management of exposures in the prehospital and hospital settings.

Abstract
The relative toxicity of anxiolytic and hypnotic drugs commonly used for self-poisoning was assessed using data on suicides, prescriptions and non-fatal self-poisonings in England, 2005-2012. Data on suicide by self-poisoning were obtained from the Office for National Statistics, information on intentional non-fatal self-poisoning was derived from the Multicentre Study of Self-harm in England and data on prescriptions in general practice from the Clinical Practice Research Datalink. We used two indices of relative toxicity: fatal toxicity (the number of fatal self-poisonings relative to the number of individuals prescribed each drug) and case fatality (the number of fatal relative to non-fatal self-poisonings). Diazepam was the reference drug in all analyses. Temazepam was 10 times (95% confidence interval 5.48-18.99) and zopiclone/zolpidem nine times (95% confidence interval 5.01-16.65) more toxic in overdose than diazepam (fatal-toxicity index). Temazepam and zopiclone/zolpidem were 13 (95% confidence interval 6.97-24.41) and 12 (95% confidence interval 6.62-22.17) times more toxic than diazepam, respectively (case-fatality index). Differences in alcohol involvement between the drugs were unlikely to account for the findings. Overdoses of temazepam and zopiclone/zolpidem are considerably more likely to result in death than overdoses of diazepam. Practitioners need to exercise caution when prescribing these drugs, especially for individuals who may be at risk of self-harm, and also consider non-pharmacological options.

Abstract
Background Most fatal poisonings occur outside the hospital and the victims found dead. The purpose of this study was to determine the general pattern and patient demographics of fatal poisonings in Northern Finland. In particular, we wanted to analyze differences between pre-hospital and in-hospital deaths. Methods All fatal poisonings that occurred in Northern Finland in 2007–2011 were retrieved from the Cause of Death Registry provided by Statistics Finland. We noted the patient demographics, causal agents, and other characteristics of the poisoning events. Results A total of 689 fatal poisonings occurred during the study period, of which only 42 (6.1%) reached the hospital alive. Those who died pre-hospital were significantly younger (50 vs. 56 years, p = 0.04) and more likely to be male (77% vs. 57%, p = 0.003). Cardiopulmonary resuscitation was attempted less often in pre-hospital cases (9.9% vs. 47.6%, p < 0.001). Ethanol was more frequently the main toxic agent in pre-hospital deaths (58.4% vs. 26.2%, p < 0.001), and multiple ingestions were more common (52.2% vs. 35.7%, p < 0.001) in pre-hospital deaths. Discussion Most of the pre-hospital fatal poisoning victims are found dead and the majority of in-hospital victims are admitted to hospital in an already serious condition. According to results of this and former studies, prevention seems to be the most important factor in reducing deaths due to poisoning. Conclusions The majority of poisoning-related deaths occur pre-hospital and are related to alcohol intoxication and multiple ingestions.

Abstract
CONTEXT Poisoning is an important category of avoidable deaths in Norway and an important public health issue. Close monitoring of any development in this field is essential for effective preventive measures. OBJECTIVE To assess the pattern and trends of poisoning mortality in Norway from 2003 to 2012 based on official mortality data. MATERIALS AND METHODS This is a population-based registry study. We analyzed the underlying external cause of death data, in order to assess poisoning deaths (ICD-10) by accidents (X40-X49); intentional self-harm (suicide) (X60-X69); assault (homicide) (X85-X90); and poisoning of undetermined intent (Y10-Y19). We compared poisoning deaths to other injury mechanisms and used multiple injury cause data to identify substances involved in poisoning deaths. Poisson regression was applied to estimate the trend. RESULTS Poisoning was the second leading mechanism of injury deaths in Norway from 2003 to 2012, causing between 424 and 496 deaths each year. The rates of poisoning deaths varied between 8 and 11 per 100,000 inhabitants, with a peak in 2004. About 3366 of the 4620 poisoning deaths in the decade were accidental. Opioids were the most common causative agents. Heroin caused 150 deaths in 2004. The numbers fell to 63 in 2012 but showed great yearly variations. Deaths by methadone increased from 24 in 2003 to 61 in 2012. DISCUSSION Poisoning mortality rates declined from 2003 to 2012. Interpretation of the data, however, should be done with caution, and comparison with other countries may be biased due to differences in data production procedures. Evaluation of the effect of preventive measures to reduce mortality should be emphasized. CONCLUSION Poisonings remain a significant cause of mortality by injury in Norway. Emphasis should be placed on following the trends closely, especially regarding methadone deaths.

Abstract
BACKGROUND In Oslo, the majority of patients with acute poisoning are treated in primary care, at an emergency outpatient clinic with limited diagnostic and treatment resources. We describe the poisonings currently seen in this setting. We compare our findings with previous studies, with special concern for the appearance of new toxic agents, and changes in overall numbers and patterns of poisoning. METHODS Observational study. Patients above the age of 12 years presenting at Oslo Accident and Emergency Outpatient Clinic (Oslo Legevakt) with acute poisoning were included consecutively from October 2011 through September 2012. Physicians and nurses registered data on preset forms. Main outcome measures were toxic agents, age, sex, intention, referral and time of presentation. RESULTS There were 2923 episodes of acute poisoning in 2261 patients. Median age of the patients was 32 years, and 1430 (63%) were males. The most frequent toxic agents were ethanol in 1684 (58%) episodes, heroin in 542 (19 %), benzodiazepines in 521 (18%), amphetamine in 275 (9%), fire smoke in 192 (7%), gamma-hydroxybutyrate (GHB) in 144 (5%), and cannabis in 143 (5%). In 904 (31%) poisonings there were more than one toxic agent. In 493 episodes (17%), the patient was hospitalised, and in 60 episodes (2%) admitted to a psychiatric ward. Most poisonings, 2328 (80%), were accidental overdoses with substances of abuse, 276 (9%) were suicide attempts, and 312 (11%) were accidents. Among ethanol poisonings in patients above the age of 26 years, 685/934 (73%) were in males, and 339/934 (36%) presented during weekends. However, among ethanol poisonings in patients under the age of 26 years, 221/451 (49 ) were in females, and 297/451 (66%) presented during weekends. CONCLUSIONS The poisonings treated in this primary care setting were mostly due to accidental overdoses with ethanol or other substances of abuse. There is a disconcerting weekend drinking pattern among adolescents and young adults, with young females presenting as often as young males with ethanol poisoning.

A systematic review of the epidemiology of unrecorded alcohol consumption and the chemical composition of unrecorded alcohol. Addiction 2014; 109:880-93.

Abstract
BACKGROUND AND AIMS Unrecorded alcohol constitutes about 30% of all alcohol consumed globally. The aims of this systematic review were to determine the epidemiology (occurrence, types, prevalence) of unrecorded alcohol consumption in different countries/regions, analyse the chemical composition of unrecorded alcohol and examine health outcomes caused by the consumption of unrecorded alcohol, based on either epidemiology or toxicology. METHODS A systematic search for, and qualitative analysis of, papers with empirical results on the different categories of unrecorded alcohol, based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS Unrecorded alcohol was widespread in all regions of the world. Artisanal fermented beverages and spirits were the most common categories of unrecorded alcohol globally, and were available on all continents. In India, industrially produced spirits (country spirits) were most prevalent. In Russia and countries of the former Soviet Union, surrogate alcohols complemented artisanal spirits. Cross-border shopping was the most prevalent method of obtaining unrecorded alcohol in parts of Europe. Ethanol was the most harmful ingredient of unrecorded alcohol, and health consequences due to other ingredients found in unrecorded alcohol were scarce. However, as unrecorded alcohol is usually the least expensive form of alcohol available in many countries, it may contribute to higher rates of chronic and irregular heavy drinking. CONCLUSIONS Very large amounts of alcohol are produced globally that go unrecorded. The primary harm from this kind of alcohol arises from the fact that it is typically much cheaper than licit alcohol.

Abstract
The misuse and abuse of prescription medications in the United States continues to increase despite interventions by health care professionals, regulatory, and law enforcement agencies. Opioid analgesics are the leading class of prescription drugs that have caused unintentional overdose deaths. Benzodiazepines when taken alone are relatively safe agents in overdose. However, a 5-fold increase in deaths attributed to benzodiazepines occurred from 1999 to 2009. Emergency department visits related to opioid analgesics increased by 111% followed by benzodiazepines 89%. During 2003 to 2009, the 2 prescriptions drugs with the highest increase in death rates were oxycodone 264.6% and alprazolam 233.8%. Therefore, benzodiazepines have a significant impact on prescription drug unintentional overdoses second only to the opioid analgesics. The combination prescribing of benzodiazepines and opioid analgesics commonly takes place. The pharmacokinetic drug interactions between benzodiazepines and opioid analgesics are complex. The pharmacodynamic actions of these agents differ as their combined effects produce significant respiratory depression. Physician and pharmacy shopping by patients occurs, and prescription drug-monitoring programs can provide important information on benzodiazepine and opioid analgesic prescribing patterns and patient usage. Health care professionals need to inform patients and work closely with regulatory agencies and legislatures to stem the increasing fatalities from prescription drug unintentional overdoses.

Abstract
Fatal alcohol and drug poisonings in Finland during the years 2004-2009 were studied. Cases were divided into those that occurred outside the hospitals (the majority of cases) and those that occurred within the hospitals (the minority of cases). Differences and similarities between the two groups were analysed. The postmortem toxicological investigation of all sudden and unexpected deaths in Finland is centralised at the Department of Forensic Medicine, University of Helsinki. We examined each fatal poisoning separately and verified the cause and place of death as well as the age and sex of the deceased. Fatal poisonings, including suicides, have remained unchanged for many years from the same high level, that is, about 1200 cases annually (22/100,000 inhabitants). The number of patients dying in hospitals due to poisoning has also remained stable (55-70 patients/year). However, the toxic agents involved in such poisonings have changed and deaths due to opioids are now being more numerous. The number of fatal unintentional drug poisonings rose significantly from 191 to 341 (3-6/100,000 inhabitants, p < 0.001) during the study years, and the difference between poisonings caused by drugs or alcohol also changed significantly (p < 0.001). Diminishing substantially, the number of all fatal poisonings will be challenging because of the high percentage of suicides. However, a reduction in unintentional drug overdoses, which are presently on the rise, should be possible.

Abstract
BACKGROUND AND AIM The Nordic countries provide a suitable setting for comparing trends in suicide mortality. The aim of this report is to compare suicide trends by age, gender, region and methods in Denmark, Finland, Iceland, Norway and Sweden 1980-2009. METHODS Suicide statistics 1980-2009 were analyzed for men and women aged 15 years and above and the age group 15-24 years. Regional suicide rates in 2009 were presented in maps. RESULTS The suicide rates across the Nordic countries declined from 25-50 per 100,000 in 1980 to 20-36 in 2009 for men and from 9-26 in 1980 to 8-11 in 2009 for women. The rates in Finland were consistently higher than those of the other countries. A significant increase of suicides in young women in Finland and Norway and a lack of a decline among young women in Sweden were noted. The male- female ratio of suicide converged to approximately 3:1 across the region during the study period. Rural areas in Finland, Norway and Sweden saw the highest suicide rates, whereas the rates in the capital regions of Denmark, Norway and Sweden were lower than the respective national rates. CONCLUSIONS We hold that the overall decline of suicide rates in the Nordic countries reflects the socio-economic development and stability of the region, including the well-functioning healthcare. The increasing rates in Finland and Norway and the unchanged rate in Sweden of suicide in young women are an alarming trend break that calls for continued monitoring.

Abstract
OBJECTIVE To examine unintentional alcohol and drug poisoning in association with substance use disorders (SUDs) and mood and anxiety disorders. METHOD International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) external-cause-of-injury codes on discharge records of patients ages 12+ years from the 2010 Nationwide Inpatient Sample were examined to identify cases with unintentional alcohol poisoning (E860) and/or drug poisoning (E850-E858). ICD-9-CM diagnosis codes were examined to identify comorbid alcohol dependence, drug dependence, tobacco use disorder, and mood/anxiety disorders. Poisson regression was used to derive risk ratios to assess the associations between these comorbid conditions and alcohol/drug poisoning. RESULTS Estimated numbers of hospitalisations related to unintentional alcohol and drug poisoning were, respectively, 5623 and 60 423 in men, and 3147 and 68 568 in women. For both sexes, the proportion with SUDs or mood/anxiety disorders was significantly higher among inpatients with alcohol and drug poisoning than among all inpatients. Estimated risk ratios indicated strong relationships of SUDs and mood/ anxiety disorders with unintentional poisoning from alcohol and drugs. The strongest association was between alcohol dependence and alcohol poisoning for both sexes. Significant associations also existed between drug dependence and drug poisoning, and mood/anxiety disorders and poisoning from alcohol and drugs. CONCLUSIONS SUDs and mood/anxiety disorders are key risk factors for unintentional poisoning by alcohol and drugs among inpatients in the USA. Effective treatments of these disorders should be targeted as poisoning prevention efforts. Future studies are needed to clarify a potential bias in the data due to differential inpatient mental condition screening practices.

Abstract
Background Up to date information on poisoning trends is important. This study reports the epidemiology of all hospitalized acute poisonings in Oslo, including mortality, follow-up referrals, and whether the introduction of over-the-counter sales of paracetamol outside pharmacies had an impact on the frequency of poisonings. Methods All acute poisonings of adults (≥16 years) treated at the five hospitals in Oslo from April 2008 to April 2009 were included consecutively in an observational cross-sectional multicentre study. A standardized form was completed by the treating physician, which covered the study aims. All deaths by poisoning in and outside hospitals were registered at the Institute of Forensic Medicine. Results There were 1065 hospital admissions of 912 individuals; 460 (50%) were male, and the median age was 36 years. The annual incidence was 2.0 per 1000. The most frequent toxic agents were ethanol (18%), benzodiazepines (15%), paracetamol (11%), and opioids (11%). Physicians classified 46% as possible or definite suicide attempts, 37% as accidental overdoses with substances of abuse (AOSA), and 16% as other accidents. Twenty-four per cent were discharged without any follow-up and the no follow-up odds were highest for AOSA. There were 117 deaths (eight in hospital), of which 75% were males, and the median age was 41 years. Thus, the annual mortality rate was 25 per 100 000 and the in-hospital mortality was 0.8%. Opioids were the most frequent cause of death. Conclusions The incidence of hospitalized acute poisonings in Oslo was similar to that in 2003 and there was an equal sex distribution. Compared with a study performed in Oslo in 2003, there has been an increase in poisonings with a suicidal intention. The in-hospital mortality was low and nine out of ten deaths occurred outside hospitals. Opioids were the leading cause of death, so preventive measures should be encouraged among substance abusers. The number of poisonings caused by paracetamol remained unchanged after the introduction of over-the-counter sales outside pharmacies and there were no deaths, so over-the-counter sales may be considered safe.

Abstract
AIM To study poisoning mortality from birth to the end of teenage. METHODS Registry study within the Danish population including all deaths from poisoning in the 0-19-year age groups for the years 1970-2006. RESULTS Poisoning mortality was age dependent with a modest peak in preschool children because of accidents and a very steep increase from 0.1/10(5) person years (p.y.) at 12 years to 6.1/10(5) p.y. at 19 years. Accidents, suicide and undetermined manner of death all contributed to the increase. A significant proportion of accidental and undetermined manner of death was caused by opioides and probably abuse related. During the study period, mortality decreased by more than 50% with all manners of death contributing significantly to the decline. Carbon monoxide poisoning was the overall dominating cause of death and contributed most to reduction in mortality. Poisoning death caused by opioides and unspecified drugs was unchanged over time. CONCLUSION Poisoning mortality among the youngest Danish children was dominated by accidental poisonings. During teenage, the level and pattern of adults was approached with respect to suicidal and abuse related deaths. A fall in mortality since mid-eighties was explained by fewer deaths from carbon monoxide poisoning.

Abstract
AIM To map mortality and morbidity of poisonings in Denmark, Finland, Iceland, Norway and Sweden in 2007 and undertake a comparison with a corresponding study in 2002. METHODS Morbidity was as for 2002 defined as acute poisoning (ICD-10 codes, main and subsidiary diagnoses) treated in hospitals. The figures were extracted from the National Patient/Hospital Registers. Deaths recorded as acute poisoning (using corresponding ICD-10 codes) were collected from the National Cause of Death Registers. RESULTS Annual mortality of acute poisonings per 100,000 inhabitants (rate) for 2007 was 22.4 in Finland, an important increase from 16.7 per 100,000 in 2002. The increase was mainly due to a change in coding of alcohol, but also represented a slight increase in fatal alcohol intoxications per se. The poisoning death rate in the other Nordic countries varied between 8-13 and was at the same level as for 2002. The morbidity rates for 2007 between 158-285 per 100,000 inhabitants represented a slight increase compared to 2002 figures. CONCLUSION The increase in poisoning death rate for alcohol, and thus total rate in Finland in 2007 compared to 2002, has further increased the gap to the other Nordic countries. Poisoning morbidity rates in the Nordic countries are of the same level, but the variability shown indicates that more harmonization and collaboration is needed to increase the data quality.

Abstract
BACKGROUND Mortality, including suicide and accidents, is elevated in self-harm populations. Although risk factors for suicide following self-harm are often investigated, rarely have those for accidents been studied. Our aim was to compare risk factors for suicide and accidents. METHOD A prospective cohort (n=30 202) from the Multicentre Study of Self-harm in England, 2000-2007, was followed up to 2010 using national death registers. Risk factors for suicide (intentional self-harm and undetermined intent) and accidents (narcotic poisoning, non-narcotic poisoning, and non-poisoning) following the last hospital presentation for self-harm were estimated using Cox models. RESULTS During follow-up, 1833 individuals died, 378 (20.6%) by suicide and 242 (13.2%) by accidents. Independent predictors of both suicide and accidents were: male gender, age 35 years (except accidental narcotic poisoning) and psychiatric treatment (except accidental narcotic poisoning). Factors differentiating suicide from accident risk were previous self-harm, last method of self-harm (twofold increased risks for cutting and violent self-injury versus self-poisoning) and mental health problems. A risk factor specific to accidental narcotic poisoning was recreational/illicit drug problems, and a risk factor specific to accidental non-narcotic poisoning and non-poisoning accidents was alcohol involvement with self-harm. CONCLUSIONS The similarity of risk factors for suicide and accidents indicates common experiences of socio-economic disadvantage, life problems and psychopathology resulting in a variety of self-destructive behaviour. Of factors associated with the accidental death groups, those for non-narcotic poisoning and other accidents were most similar to suicide; differences seemed to be related to criteria coroners use in reaching verdicts. Our findings support the idea of a continuum of premature death.
