Repeated hospital admission for intentional poisonings among older adults - a Swedish national register-based study.

BACKGROUND: Poisoning injuries is an increasing concern among older people, and so is the repetition of intentional poisonings. To date, few studies have documented the pattern and individual risk factors for repeated poisonings. This national study aims to shed light on the burden, pattern, and health-related risk factors of repeated intentional poisoning leading to hospitalization or death among older Swedish adults (50 years and older), with a focus on the year following a first event. METHODS: We conducted a nationwide register-based cohort study of people aged 50-100, hospitalized for intentional poisoning (ICD10: X60-69) during 2006-2016 (n = 15,219) and re-hospitalized by poisoning of any intent within a year (n = 1710), i.e., up to the end of 2017. We considered in turn, the distribution of the second poisoning in 30-day intervals stratified by intent; poisoning lethality within a month and a year; and the sex-specific association between health conditions and being re-hospitalized for intentional poisoning within one year as compared to being hospitalized only once using logistic regression (odds ratios (OR) with 95% confidence intervals (95% CI)). RESULTS: Following an intentional poisoning, re-hospitalization within a year was predominantly for a new intentional poisoning (89.7%) and occurred most typically within a month (median 4 days). Death within 30 days occurred in similar proportion for the first and second poisoning (2.3% vs. 2.1% respectively). Among both men and women, comorbidity of psychiatric illness was strongly associated with re-hospitalization for intentional poisoning (adjusted ORs = 1.70; 95% CI = 1.45-2.01 and 1.89 (95% CI = 1.60-2.19) respectively). CONCLUSION: Most re-hospitalizations within a year after intentional poisoning are also for intentional poisoning and occur most typically within days. Re-hospitalization is associated with several conditions that are characteristic of poor mental health and there are more similarities than differences between men and women in that respect.

Impact of COVID-19 restrictions on self-poisoning behaviour with mild analgesics in Danish youth.

BACKGROUND: The COVID-19 pandemic prompted the implementation of precautions to contain the disease, including lockdowns and social isolation. Previous studies have investigated suicide rates among children and adolescents during the pandemic and have found varying results. We speculated how the two lockdowns influenced suicidal behaviour in children and adolescents in Denmark. OBJECTIVE: This study aimed to investigate the effect of lockdowns during the COVID-19 pandemic on suicide attempts, as measured by the incidence rate in all self-poisonings with mild analgesics among children and adolescents. METHODS: This national Danish registry-based study on children and adolescents used Poisson regression and interrupted time series analysis to examine the incidence rates and trends of self-poisonings with mild analgesics from 2019 to mid-2021. RESULTS: For the period of this study, 1655 self-poisonings were registered. During the first lockdown, there was a slight, not statistically significant, decrease in self-poisoning rates (incidence rate ratio [IRR]) 0.98) compared to no lockdown. During the second lockdown, there was a significant increase in self-poisonings for the whole Danish population (IRR 1.85) with girls being slightly higher at risk (IRR 1.87). Being a girl or between the ages of 13-17 years old were risk factors for self-poisoning. CONCLUSION: These findings indicate that the restrictions enforced during the second lockdown greatly impacted youth mental health, especially girls, leading to an 85% increase in self-poisonings. We hope for increased awareness of mental health in children and adolescents during possible future lockdowns.

[Features of lung damage in baclofen poisoning]. / Osobennosti povrezhdeniya legkikh pri otravlenii baklofenom.

OBJECTIVE: To reveal pathological lung changes in baclofen poisoning and to assess their dynamics. MATERIAL AND METHODS: The experiment included 20 mature (at age 20 weeks) male rats of Wistar line weighing 290-350 gr. The animals were divided into 3 study groups (5 rats in each) depending on experiment's duration after 85 mg/kg baclofen administration: 3, 4.5 and 24 h in the 1st, 2nd and 3rd groups, respectively. Control group consisted of 5 animals without baclofen administration. RESULTS: A number of pathological reactions, including circulatory disorder (venular and capillary congestion, hemorrhage in interalveolar septa, alveoli, sludge) and the appearance of emphysema loci (interalveolar septa at emphysema loci are thinned), alternating with atelectases and dystelectases. The area taken up by vessels after 4.5 h. baclofen administration was statistically significantly higher than in control group, and after 24 h. - statistically significantly higher than in 4.5 h. The area with white blood cells and WBC/IAP ratio after 4.5 h of baclofen administration were statistically significantly higher than in control group after 3 and 24 h of administration. The number of white blood cells, giving PAS positive reaction, increases during baclofen administration. The complex of pathological lung changes, revealed by ourselves, has a certain dynamics. CONCLUSION: The data on morphological lung changes combined with results of chemical examination can be used to diagnose baclofen poisoning and to determine the time elapsed since this medicine administration.

[Assessment of histological changes in the lungs and Bax and Bcl-2 expression in bronchial epithelium, alveolar type 1 cells and neutrophils of rats in poisoning with baclofen]. / Otsenka gistologicheskikh izmenenii legkikh i ekspressii Bax i Bcl-2 v bronkhial'nom epitelii, al'veolotsitakh 1-go tipa i neitrofilakh krys pri otravlenii baklofenom.

OBJECTIVE: To study the histological changes in lung of rats, evaluate their dynamics and determine the Bax and Bcl-2 genes expression in bronchial epithelium, alveolar type 1 cells and neutrophils at different times after the administration of baclofen. MATERIAL AND METHODS: The experiment was conducted on 20 mature (at the age of 20 weeks) male Wistar rats with a mass of 290-350 g, distributed in 4 groups (5 rats in each). Animals in the control group did not receive baclofen. Rats in experimental groups received baclofen at a dose of 85 mg/kg: in the 1st group, the experiment duration was 3 hours (time to maximum observed blood drug concentration); in the 2nd group - 4.5 h (drug half-life and time to maximum observed concentration of the main drug's metabolite - beta-[p-chlorophenyl])-gamma-hydroxybutyric acid in the blood); in the 3rd group - 24 h. RESULTS: A complex of pathological reactions developed in lungs of experimental animals when baclofen muscle relaxant was administered, namely circulatory disturbances at all levels of the microvasculature (venular and capillary congestion, hemorrhages in the interalveolar septums, alveoli, sludge), emphysema, sites of which punctuated with atelectases and dystelectases. The complex of pathological changes in the lungs had a certain dynamics and reached its highest severity by the 24th hour. Bax expression was strong, while Bcl-2 expression was moderate in the immunohistochemical (IHC) study of bronchical epithelium and alveolar type 1 cells, Bax and Bcl-2 expression in neutrophils was moderate in rats of the 1st group. The expression of Bax and Bcl-2 was strong in the bronchial epithelium and alveolar type 1 cells, the expression of Bax in neutrophils was moderate, and BCL-2 - strong in animals of the 2nd group. The expression of Bax in bronchial epithelium and alveolar type 1 cells was moderate, expression of Bcl-2 in bronchial epithelium and alveolar type 1 cells - strong, expression of Bax in neutrophils - weak and expression of Bcl-2 - strong among the rats of the 3rd group. CONCLUSION: The complex of pathological changes in lungs had a certain dynamic. Data on the histological changes in lungs in combination with the results of the chemical study, can be used to diagnose the poisoning by baclofen and to establish the time since the drug was administered. The results obtained during the IHC study suggest the involvement of apoptosis in the development of lesion of bronchial epithelium and alveolar type 1 cells. In addition, the expression of Bcl-2 in epithelial cells may play a role in the process of their regeneration.

Trends in intentional and unintentional poisonings among older adults - A national register-based study in Sweden.

BACKGROUND: Among older people intentional poisoning outnumber unintentional ones. While there are indications that time trends differ by poisoning intent, studies are scarce. We assessed how the annual prevalence of intentional and unintentional poisoning changed over time, overall and by demographic groups. METHODS: We conducted a national open cohort study of individuals aged 50-100 years, resident in Sweden during 2005-2016. Individuals were followed up in population-based registers for their demographic and health attributes from 2006-2016. Annual prevalence of hospitalization and death by poisoning intent (unintentional vs. intentional or undetermined; ICD-10 definitions) were compiled for the categories of four demographic attributes (age, sex, marital status, and birth cohort "baby boomers"). The time trends were assessed by multinomial logistic regression with year as an independent variable. RESULTS: The annual overall prevalence of hospitalization and death by intentional poisonings consistently exceeded that of unintentional poisonings. There was a significant downward trend in intentional poisonings but not in unintentional ones. This difference in trends also applied when considering men and women separately, married and unmarried people, the young-old individuals (but not the older- or oldest-old ones), and the baby boomers and non-baby boomers. The largest demographic differences within intent were found between married and unmarried people, and the smallest one between men and women. CONCLUSION: As expected, the annual prevalence of intentional poisonings considerably exceed that of unintentional ones among Swedish older people. The recent trends reveal a significant reduction of intentional poisonings, consistent across a range of demographic attributes. The scope for action regarding this preventable cause of mortality and morbidity remains considerable.

Toxic Exposures Among Young Children One Year into the COVID-19 Pandemic: A Retrospective Review of Three San Francisco Bay Area Emergency Departments.

BACKGROUND: Daycare and school closures prompted by shelter-in-place orders may have increased opportunities for unintentional ingestions among young children. OBJECTIVES: We examined emergency department (ED) presentations for toxic exposures among young children during the COVID-19 pandemic in the San Francisco Bay Area, which had some of the strictest and most prolonged shelter-in-place policies in the United States. METHODS: We performed a retrospective cross-sectional study of children 0 to 5 years of age who presented with an ED International Statistical Classification of Diseases and Related Health Problems, Tenth Revision diagnosis code of toxic exposure within a tertiary care hospital system between March 16, 2016 and March 15, 2021. We considered the period after March 16, 2020 to represent the pandemic. RESULTS: During the pandemic, the absolute number of poisonings among young children remained stable. Overall, ED encounters within this cohort decreased by 55%, which doubled the relative toxic exposure rate per 1000 ED encounters from 4.99 (95% confidence interval [CI] 3.19-5.90) to 9.79 (95% CI 8.09-11.49). Rates of admission, severe medical complications, operating room case requests, and length of stay were not significantly different. Shelter-in-place was associated with significantly higher odds of cannabis ingestion (odds ratio = 2.70, 95% CI 1.60-4.49). CONCLUSION: Despite dramatic decreases in overall ED patient volumes, the absolute number and severity of toxic exposures were similar during the pandemic compared with previous years. © 2022 Elsevier Inc.

Trends in characteristics of fentanyl-related poisonings in the United States, 2015-2021.

Background: Fentanyl-related deaths continue to increase in the United States; however, most national studies focus on fatal overdose. More research, including data on nonfatal overdose, is needed.Objective: We examined trends in characteristics of fatal and nonfatal fentanyl-related poisonings ("exposures") in the US.Methods: National Poison Control data were examined to estimate trends in characteristics of reported exposures between 2015 and 2021 (N = 15,391; 38.7% female). We also delineated correlates of experiencing a major adverse effect or death.Results: The proportion of exposures increased among all age groups between ages 13 and 39 (ps < .05) with the largest increase among those age 13-19 (a 127.8% increase). With respect to reasons for use, the proportion of cases involving fentanyl "abuse" increased by 63.8% (p < .001). The proportion involving fentanyl inhalation increased 427.6% from 5.7% to 29.9% and injection increased from 6.7% to 9.6%, a 42.3% increase (ps < .01). The proportion also increased for co-use of methamphetamine (by 669.0%), cocaine (by 374.0%), and heroin (by 159.5%). The proportion of major adverse effects increased from 15.5% to 39.6% (p < .001). In the multivariable model, "abuse", suspected suicide attempts, and use via inhalation were risk factors for experiencing a major effect or death, and misuse, ingestion, dermal use, and co-use of methamphetamine were associated with lower risk.Conclusion: Poison Control data suggest that characteristics of individuals exposed to fentanyl continue to shift, with use via inhalation increasing and medical outcomes of nonfatal poisonings becoming more severe. These results complement mortality data and inform prevention and harm reduction efforts.

Rates of reported codeine-related poisonings and codeine prescribing following new national guidance in Ireland.

PURPOSE: The aims of this study were to examine a national database to assess codeine poisonings before and after the new guidance for pharmacists while also evaluating rates of codeine prescriptions following the introduction of restrictions on supply. METHODS: Anonymised enquiry data of reported poisoning cases were reviewed for a period from 2005 to 2016 inclusive. The rate of pharmacy claims for codeine containing products was also examined using the national pharmacy claims database. Segmented regression analysis was used to detect changes in poisonings and claims before and after the new guidance. RESULTS: There were 1851 codeine-related poisonings reported over the study period. An annual decline was evident with a significant 33% reduction from 2010 to 2011 (ß2 coefficient for level change, 42.1; 95% CI, -68.1 to -16.0; P = 0.006). Following 2011, the declining rate of codeine poisonings plateaued. Analysis of the national pharmacy claims data revealed no change in the reimbursement rate for co-codamol products restricted by the guidance in 2010 (Incidence rate ratio 1.04, 95% CI, 0.997-1.08; P = 0.07). There was no corresponding increase in the reimbursement of alternative opioid medications. CONCLUSIONS: New guidance on codeine supply coincided with an initial reduction in reported codeine poisoning cases. This reduction was in keeping with the previous trend. However, this was without an increase in the prevailing rate of prescription claims for these products or potential substitutes. Policymakers may consider further restriction of codeine products to improve public health outcomes.

Foodborne infections and intoxications in Poland in 2017

AIM: The purpose of this study is to assess the epidemiological situation of food poisonings and infections in Poland in 2017. MATERIALS AND METHODS: The evaluation was based on the analysis of information sent to Department of Epidemiology NIPH-NIH through ROE (pol. Rejestr Ognisk Epidemicznych)- (an electronic system created for uploading, transfer and analysis of data acquired during the outbreak investigations). Additional sources for the analysis were NIPH-NIH annual bulletins (Czarkowski MP et al. "Infectious diseases and poisonings in Poland", 2011-2017. Warsaw, NIPH-NIH and GIS). RESULTS: In 2016 a total number of 926 foodborne infections and intoxications outbreaks were reported in which 27 702 persons were exposed and 7 416. A total number of 2 502 of patients were hospitalized. The most frequent etiological agent of outbreaks was hepatitis A virus (HAV) (27.1%). The most frequent cause of infection for all outbreaks cases was Salmonella sp. ­ 37.2%, especially serotype Enteritidis (32.2%). Among other agents rotaviruses caused 9.3% of outbreaks and noroviruses 14.5%. In 12.2% of outbreaks no etiological agent was found. The most frequent place of an outbreak was private household- 560 outbreaks (60.4%), and after that- hospital- 155 outbreaks (16.7%). In 86.8% of outbreaks no vehicle was found and in remaining the most frequent vehicle were eggs and egg products- 5.6% % of all outbreaks. CONCLUSIONS: Increasing yearly trend of Salmonella Enteritidis outbreaks, and high proportion of eggs and egg products as vehicles in those outbreaks point towards necessity of microbiological surveillance enchantment in relation to abovementioned products. Dynamic increase in HAV outbreaks is a good example of how a pathogen with high epidemic potential could spread in susceptible population.

The problem of acute pesticide poisonings of agricultural workers in ukraine under the conditions of the new business patterns.

OBJECTIVE: Introduction: Due to introduction of new forms of agriculture and transformation of the treatment and preventive service in recent years, there has been a false impression of a sharp decrease in the level of occupational morbidity among agricultural workers 30 % to 25 % in the structure of general occupational morbidity in the 80-90s down to 0.2-0.4 %. The aim: Summarize data on the prevalence, causes, structure of acute pesticide poisoning in agricultural workers at the current stages of its reform in order to improve preventive measures. PATIENTS AND METHODS: Materials and methods: Data on the prevalence, causes and structure of 647 cases of acute pesticide poisoning in agricultural workers over the past 25 years have been summarized; staff of the Scientific Toxicology Center took part in the sanitary-hygienic investigation and establishment of the diagnosis. RESULTS: Results: The causes for the development, aetiology and structure of 647 cases of acute pesticide poisoning, among which 522 cases of acute poisoning of field beet growers with 2,4-D-based herbicides (80.7 %), 60 cases (9.3 %) of OPC poisoning, 36 cases of beet growers poisoning with sulphonylurea-based herbicides, 14 patients with acute synthetic pyrethroid poisoning, and isolated cases (15 patients) of intoxication with aluminium phosphide, dithiocarbamates, Vitavax, and Fipronil were analysed. CONCLUSION: Conclusions: Analysis of the causes of the development and structure of poisoning has allowed to optimize the complex of preventive measures to strengthen sanitary control over the implementation of individual and public safety hygienic regulations during storage and use of pesticides.

Social and economic characteristics of those experiencing hospitalizations due to opioid poisonings.

Hospitalizations due to opioid poisonings are increasing. While considerable information is available on the demographic and geographic distribution of opioid-related events, national data on the social and economic circumstances of those experiencing these events are limited. This study uses data from the National Household Survey (2011) linked to the Discharge Abstract Database (2011 to 2016) to provide the first national-level estimates of the socio-economic characteristics of individuals experiencing opioid-related hospitalizations. Results reveal elevated hospitalization rates among people who have lower levels of income and education, are unemployed or out of the labour force, identify as Indigenous, live in lone-parent households, and spend more than 50% of their household income on housing. Understanding the circumstances of individuals who experienced adverse opioid events will help inform policies addressing potential determinants.

Foodborne infections and intoxications in Poland in 2016

AIM: The purpose of this study is to assess the epidemiological situation of food poisonings and infections in Poland in 2016. MATERIALS AND METHODS: The evaluation was based on the analysis of information sent to Department of Epidemiology NIPH-NIH through ROE (Pol. Rejestr Ognisk Epidemicznych)- (an electronic system created for uploading, transfer and analysis of data acquired during the outbreak investigations). Additional sources for the analysis were NIPH-NIH annual bulletins (Czarkowski MP et al. "Infectious diseases and poisonings in Poland", 2010-2016. Warsaw, NIPH-NIH and GIS). RESULTS: In 2016 a total number of 680 foodborne infections and intoxications outbreaks were reported in which 22 908 persons were exposed and 7 186 (out of which 38% were children up to 14 years of age) got sick. Hospitalization was required for 1 603 of patients. The most frequent etiological agent was Salmonella sp. ­ 37,6%, 3 and 28,4% of cases). Viruses were responsible for 22,5% of outbreaks and 28,6 % of cases (And among them rotaviruses- 10,8% of outbreaks and 5,2% of cases and noroviruses- 11,1% of outbreaks and 23,3% of cases). In 27,5% of outbreaks no etiological agent was found. Just as in 2015 private household was the most frequent place of an outbreak- 323 outbreaks (47,5%), and after that- hospital- 135 outbreaks (19,9%). In 2016 in more than 81% of outbreaks no vehicle was found and in remaining the most frequent vehicle were eggs and egg products) (25% of outbreaks of known vehicle). CONCLUSIONS: The increase in the both percentage of reported salmonellosis cases among the group of bacterial foodborne infections and the increase of foodborne outbreaks of Salmonella Enteritidis etiology along with the fact of the occurrence of large, multistate outbreak of this etiology with Polish eggs as a vehicle indicates an alarming situation and the necessity of microbiological surveillance enchantment in relation to abovementioned products. Moreover an increase in the percentage of unknown etiology outbreaks, in which clinical symptoms of cases suggest viral etiology indicates the need for more frequent testing oriented for those pathogens during epidemiological investigations.

[Concise history of toxicology - from empiric knowledge to science]. / A toxikológia rövid története ­ a tapasztalattól a tudományig.

Toxicology is a science of poisonings by xenobiotics and endogenous physiological changes. Its empiric roots may be traced back to the emerging of the human race because the most important pledge of our predecessors' survival was the differentiation between eatable and poisonous plants and animals. In the course of social evolution, there were three main fields of using poisons: 1) hunting and warfare, 2) to settle social tensions by avoiding military conflicts through hiding strategy of eliminating enemies by toxic substances, 3) medicines applied first as anti-poisons and later by introducing strong substances to defeat diseases, but paradoxically active euthanasia is also a part of the whole story. The industrial revolution of the 19th century changed the sporadic occupational diseases to mass conditions. Later the chemical industry and subsequently the mass production of synthetic materials turned out as a global environmental catastrophe. This latest change initiated the emerging of ecological toxicology which is a future history of the concerning ancient science. Orv Hetil. 2018; 159(3): 83-90.

Retrospective evaluation of adult poisoning cases admitted to emergency department of a University Hospital in Turkey.

OBJECTIVE: We aimed to evaluate demographic, etiological, clinical features, and prognosis of poisoning cases applied to a tertiary emergency department retrospectively. MATERIALS AND METHODS: The recordings of poisoning cases aged 18 years old and over which applied to the department of emergency medicine between the dates of 2010-2015 were examined. Age, gender, admission date, amount of time passed since exposure to the poisonous substance, application method, cause of poisoning, laboratory findings at arrival, vital signs, type of poisonous substance, the way of taking, treatment method in urgent care, consultation need, and the outcome of cases were recorded. RESULTS: Of the poisoning cases, 437 (52.1%) were female, and 402 (47.9%) were male. The mean age was calculated as 33.50. When the cause of poisonings are examined; 456 patients were found to be poisoned by a suicide attempt, 350 were accidentally poisoned, and 33 were poisoned by treatment complication. As the causing substance of poisoning, medicinal drugs were found in 465 cases (55.4%), carbon monoxide in 205 cases (24.4%), and narcotics in 119 cases (14.2%). Of medicinal drug poisonings, 221 (46.8%) were multiple drug intake. It was seen that 46.6% of the patients were kept under observation with only symptomatic treatment while nasogastric lavage and activated charcoal were applied in 40.2% of them. CONCLUSION: It can be suggested that poisonings are encountered more commonly in young people, especially in women, with medicinal drugs and for suicidal purposes. Drugs detected at high rates in poisonings, such as painkillers and antidepressants, should be used more cautiously.

Unintentional Pediatric Cocaine Exposures Result in Worse Outcomes than Other Unintentional Pediatric Poisonings.

BACKGROUND: Unintentional pediatric cocaine exposures are rare but concerning due to potentially serious complications such as seizures, dysrhythmias, and death. OBJECTIVES: The objectives were to assess the demographic and clinical characteristics of pediatric cocaine exposures reported to the California Poison Control System. METHODS: This is a retrospective study of all confirmed pediatric (< 6 years of age) cocaine exposures reported to the California Poison Control System from January 1, 1997-September 30, 2010. Case narratives were reviewed for patient demographics, exposure details, clinical effects, therapy, hospitalization, and final outcome. RESULTS: Of the 86 reported pediatric cocaine exposures, 36 had positive urine drug testing and were included in the study cohort. The median age at presentation was 18 months (range: 0-48 months), and 56% were male (n = 20). The most common clinical manifestations were tachycardia and seizures. The most common disposition was admission to an intensive care unit (n = 14; 39%). Eleven cases (31%) were classified as having a major effect as per American Association of Poison Control Centers case coding guidelines. One child presented in asystole with return of spontaneous circulation after cardiopulmonary resuscitation and multiple vasoactive medications. The proportion of cocaine exposures with serious (moderate or major) outcomes (66.7%; 95% confidence interval 50.3-79.8%) was higher than other pediatric poisonings reported to the American Association of Poison Control Centers during the study period (0.88%; 95% confidence interval 0.87-0.88). CONCLUSIONS: Although pediatric cocaine exposures are rare, they result in more severe outcomes than most unintentional pediatric poisonings. Practitioners need to be aware of the risk of recurrent seizures and cardiovascular collapse associated with cocaine poisoning.

Foodborne infections and intoxications in Poland in 2015

AIM: The purpose of the study is to assess the epidemiological situation of food poisonings and infections in Poland in 2015 MATERIALS AND METHODS: The evaluation was based on the analysis of information sent to Department of Epidemiology NIPH-NIH through ROE (Pol. Rejestr Ognisk Epidemicznych)- (an electronic system created for uploading, transfer and analysis of data acquired during the outbreak investigations). Additional sources for the analysis were NIZP-PZH annual bulletins (Czarkowski MP et al. "Infectious diseases and poisonings in Poland", 2007-2015. Warsaw, NIPH-NIH and GIS) RESULTS: In 2015 a total number of 560 foodborne infections and intoxications outbreaks were reported in which 21 962 persons were exposed and 7 037 (including 1 896 children up to 14 years of age) got sick. Hospitalization was required for 1 905 of patients. The most frequent etiological agent was Salmonella sp. ­ 34.3%, and 21.4 % of cases). Viruses were responsible for 23.9% of outbreaks and 29.7 % of cases (And among them rotaviruses­ 13% of outbreaks and 7.1% of cases and noroviruses­ 10.5% of outbreaks and 26.9% of cases). In 25.2% of outbreaks no etiological agent was found. Just as in 2014 private household was the most frequent place of an outbreak (235 outbreaks), and after that­ hospital (148 outbreaks). In 2014 the most frequent vehicle were cakes and desserts (25.6% of all outbreaks with known etiological agent). In 2015 the most frequent vehicle of infection were eggs and egg products) (19% of outbreaks of known vehicle). In 57.3% of outbreaks no vehicle was found or proved. Moreover in 2015 a total number of 4 outbreaks in which more than 100 cases were reported CONCLUSIONS: The increase in the number of foodborne outbreaks of Salmonella Enteritidis etiology along with the fact of eggs and egg products being the most frequent vehicle indicates an alarming situation and the necessity of microbiological surveillance enchantment in relation to those products

Fatal toxicity index of medicinal drugs based on a comprehensive toxicology database.

The fatal toxicity index (FTI) is the absolute number of fatal poisonings caused by a particular drug divided by its consumption figure. Consequently, it is a useful measure in evaluating toxicity of the drug and its relevance in fatal poisonings. In this study, we assessed the FTI of medicinal drugs in 3 years (2005, 2009, and 2013) in Finland. As the measure of drug consumption, we used the number of defined daily doses (DDD) per population in each year. There were 70 medicinal drugs in Finland for which the mean FTI expressed as the number of deaths per million DDD over the three study years was higher or equal to 0.1. The Anatomical Therapeutic Chemical (ATC) classification system was used for the classification of the active ingredients of medicinal drugs according to the organ or system which they act on. Of these 70 drugs, 55 drugs (78.6 %) acted on the nervous system (denoted by ATC code N), 11 (15.7 %) on the cardiovascular system (C), three (4.3 %) on the alimentary tract and metabolism (A), and one (1.4 %) on the musculoskeletal system (M). The nervous system drugs consisted of 20 psycholeptics, (ATC code N05), 20 psychoanaleptics (N06), eight analgesics (N02), six antiepileptics (N03), and one other nervous system drug (N07). The highest individual FTIs were associated with the opioids methadone, dextropropoxyphene, oxycodone, tramadol, and morphine; the antipsychotics levomepromazine and chlorprothixene; and the antidepressants doxepin, amitriptyline, trimipramine, and bupropion. Buprenorphine was not included in the study, because most of the fatal buprenorphine poisonings were due to smuggled tablets. A clearly increasing trend in FTI was observed with pregabalin and possibly with bupropion, both drugs emerging as abused substances.

Drug poisoning deaths in the United States, 1999-2012: a statistical adjustment analysis.

BACKGROUND: Drug poisoning mortality in the US has risen rapidly but the drugs involved are frequently unspecified on death certificates. METHODS: Reported and adjusted proportions of specific drug types involved in fatal drug poisonings were calculated using vital statistics mortality data from 1999 to 2012. The adjusted proportions were those predicted to occur if at least one specific type of drug had been identified on the death certificates of all poisoning fatalities. RESULTS: Adjusted involvement rates of opioid analgesic mentions in 2012 were 54.3 % (95 % confidence interval [CI]: 53.6 %-55 %), 40.8 % higher than the reported 38.6 % rate. Adjusted rates for all narcotics, other narcotics, sedatives, or psychotropics, and multiple drug use were 81.5 % (95 % CI: 80.9 %-82.2 %), 38.4 % (95 % CI: 37.8 %-39 %), 30 % (95 % CI: 29.4 %-30.7 %), 26 % (95 % CI: 25.4 %-26.6 %) and 42.8 % (95 % CI: 42.1 %-43.5 %) in 2012, compared to reported proportions of 60.7, 27.9, 18.7, 18 and 26.9 %. The adjustments typically had similar or slightly smaller effects on the estimates in 1999, and larger impacts on subcategories of drug types such benzodiazepines and antipsychotic medications. Based on the adjusted proportions, 22,534, 15,933, 12,457, 10,798, and 17,670 drug deaths in 2012 were estimated to involve opioid analgesics, other narcotics, sedatives, psychotropic medications, and drug combinations, compared to death certificate reports of 16,007, 11,567, 7,754, 7,467, and 11,176. CONCLUSIONS: Death certificates substantially understate the involvement of opioid analgesics, sedatives, psychotropics, and drug combinations in fatal drug poisonings. Adjustment procedures that account for cases where only unspecified drugs are reported on death certificates provide more accurate information.

Magnitude and characteristics of acute paraquat- and diquat-related illnesses in the US: 1998-2013.

BACKGROUND: Paraquat and diquat are among the most commonly used herbicides in the world. OBJECTIVES: Determine the magnitude, characteristics, and root causes for acute paraquat- and diquat-related illnesses in the US METHODS: Illnesses associated with paraquat or diquat exposure occurring from 1998 through 2011 were identified from the Sentinel Event Notification System for Occupational Risks (SENSOR)-Pesticides Program, the California Department of Pesticide Regulation (CDPR) Pesticide Illness Surveillance Program (PISP), and the Incident Data System (IDS). Cases identified by the National Poison Data System (NPDS) were reviewed for the years 1998-2003 and 2006-2013. RESULTS: A total of 300 paraquat- and 144 diquat-related acute illnesses were identified by SENSOR, PISP, and IDS. NPDS identified 693 paraquat- and 2128 diquat-related acute illnesses. In SENSOR/PISP/IDS, illnesses were commonly low severity (paraquat=41%; diquat=81%); however, SENSOR/PISP/IDS identified 24 deaths caused by paraquat and 5 deaths associated with diquat. Nineteen paraquat-related deaths were due to ingestion, seven of which were unintentional, often due to improper storage in beverage bottles. In SENSOR/PISP/IDS, paraquat and diquat-related acute illnesses were work-related in 68% (n=203) and 29% (n=42) of cases, respectively. When herbicide application site was known, the vast majority of acute paraquat-related illnesses (81%) arose from agricultural applications. Common root causes of illness were failure to use adequate personal protective equipment (PPE), application equipment failure, and spill/splash of herbicide. CONCLUSIONS: Although the magnitude of acute paraquat/diquat-related illnesses was relatively low, several fatalities were identified. Many illnesses could be prevented through stricter compliance with label requirements (e.g. ensuring proper herbicide storage and PPE use), and through enhanced training of certified applicators.

A decision analytic model to investigate the cost-effectiveness of poisoning prevention practices in households with young children.

BACKGROUND: Systematic reviews and a network meta-analysis show home safety education with or without the provision of safety equipment is effective in promoting poison prevention behaviours in households with children. This paper compares the cost-effectiveness of home safety interventions to promote poison prevention practices. METHODS: A probabilistic decision-analytic model simulates healthcare costs and benefits for a hypothetical cohort of under 5 year olds. The model compares the cost-effectiveness of home safety education, home safety inspections, provision of free or low cost safety equipment and fitting of equipment. Analyses are conducted from a UK National Health Service and Personal Social Services perspective and expressed in 2012 prices. RESULTS: Education without safety inspection, provision or fitting of equipment was the most cost-effective strategy for promoting safe storage of medicines with an incremental cost-effectiveness ratio of £2888 (95 % credible interval (CrI) £1990-£5774) per poison case avoided or £41,330 (95%CrI £20,007-£91,534) per QALY gained compared with usual care. Compared to usual care, home safety interventions were not cost-effective in promoting safe storage of other household products. CONCLUSION: Education offers better value for money than more intensive but expensive strategies for preventing medicinal poisonings, but is only likely to be cost-effective at £30,000 per QALY gained for families in disadvantaged areas and for those with more than one child. There was considerable uncertainty in cost-effectiveness estimates due to paucity of evidence on model parameters. Policy makers should consider both costs and effectiveness of competing interventions to ensure efficient use of resources.
