BJPsych Open 2024; 10:e155. [PMID: 39295440 PMCID: PMC11457225 DOI: 10.1192/bjo.2024.740] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Revised: 03/28/2024] [Accepted: 07/01/2024] [Indexed: 09/21/2024] Open
Abstract
Self-poisoning with paracetamol is the most frequently used overdose method in the UK. Psychosocial assessments were conducted by mental health clinicians with 127 consecutive individuals who presented with pure paracetamol overdoses to a large general hospital over 8 months, including asking about the source of the tablets and scoring the patients' acts on the Beck Suicide Intent scale (BSI). Patients were predominantly female (86%) and young (79% aged 12-24 years). Most had used paracetamol which was available in the home (77%). Those who purchased paracetamol for the act took double the number of tablets compared with those who used paracetamol available in the home (37 v. 18), had higher suicidal intent (mean BSI: 11 v. 7) and more often required treatment with N-acetyl cysteine (71% v. 43%). These results highlight the need for safer home storage of paracetamol and consideration of reducing pack size limits on paracetamol that can be purchased.

[PMID: 38529697 DOI: 10.1111/1742-6723.14403] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2023] [Revised: 02/24/2024] [Accepted: 02/29/2024] [Indexed: 03/27/2024]
Abstract
OBJECTIVES In June 2020, modified-release paracetamol (paracetamol-MR) preparations were up-scheduled from schedule-2 (available in pharmacy) to schedule-3 (available by request to a pharmacist only). The present study aims to ascertain whether up-scheduling affected the frequency of paracetamol-MR overdoses. METHODS This is a retrospective cohort study of two data sets from 1 June 2017 to 31 May 2022. Monash Health data were extracted using the diagnosis of paracetamol overdose coding and electronic medical records data. Calls regarding paracetamol-MR overdoses to Victorian Poisons Information Centre (VPIC) were extracted from the Poisons centre call database. We used a quasi-experimental research design with interrupted time series analysis to evaluate the immediate impact and change in trend of poisoning-related calls and ED presentations before and after June 2020. The change in proportion of paracetamol-MR cases in both databases was analysed using the Χ2 test. RESULTS The proportion of paracetamol-MR cases in both data sets did not change. From Monash Health, there was no level change in monthly paracetamol-MR overdose-related presentations following re-scheduling (rate ratio [RR] = 1.08, 95% confidence interval [CI] = 0.57-2.01). There was no change in monthly paracetamol-MR overdose-related calls to VPIC following re-scheduling (RR = 1.05, 95% CI = 0.96-1.14). CONCLUSION The proportion of paracetamol-MR overdoses did not decrease after the up-scheduling to S3. Similarly, the frequency of overdoses by month remained similar. Further limitations on access to paracetamol products may need to be considered.

Healthcare (Basel) 2024; 12:1047. [PMID: 38786457 PMCID: PMC11121457 DOI: 10.3390/healthcare12101047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Revised: 05/07/2024] [Accepted: 05/12/2024] [Indexed: 05/25/2024] Open
Abstract
Caregivers often use paracetamol in the management of pediatric illnesses without a clear rationale. This study evaluated the perception and practices of caregivers regarding the use of paracetamol in children in Southwestern Saudi Arabia. This study involved a cross-sectional design involving 373 caregivers of children under twelve. The questionnaire elucidated the reasons, usage frequency, and safe usage practices. Data were analyzed using SPSS, applying Chi-square tests and logistic regression. Most caregivers were in the age range of 31-40 years, and with intermediate education. Paracetamol was mainly used for fever, generalized pain and, diarrhea, with fewer opting for other self-care measures. Caregivers with primary or less education were more likely to perceive paracetamol as safe (AOR = 2.98 (1.3-6.73), p = 0.009) and less inclined to check warning labels (AOR: 0.11 (0.05-0.25), p < 0.001) and expiry dates (AOR: 0.063 (0.027-0.14), p < 0.001). The caregiver's education level significantly influenced the determination of treatment duration (χ2 = 21.58 (4), p < 0.001), dosage (χ2 = 30.70 (4), p < 0.001), and frequency of administration (χ2 = 17.77 (4), p = 0.001). In conclusion, inadequate health literacy can result in a lack of attention towards crucial safety information about pediatric paracetamol use. Hence, counselling initiatives should be undertaken to ensure the safe and effective use of paracetamol in children.

Abstract
(1) Background: Italy accounts for more than 150,000 deaths due to the COVID-19 pandemic, leading the top rank in SARS-CoV-2-caused deceases in Europe. A survey on the different ways by which the COVID-19 pandemic emergency was managed in the foreign European countries compared to Italy is the purpose of this paper. (2) Methods: A literature search and various mathematical algorithms to approach a rank scoring scale were used to describe in detail the different approaches used by European countries to manage the COVID-19 pandemic emergency. (3) Results: The study showed that Italy stands at the bottom ranking for COVID-19 management due to its high mortality rate. Possible causes of the observed huge numbers of hospitalization and deaths were (a) the demographic composition of the European country; (b) its decentralized healthcare system organization; (c) the role of correct pharmacology in the early stages before hospitalization. Post-mortem examinations were of paramount importance to elucidate the etiopathogenesis of COVID-19 and to tailor a suitable and proper therapy in the early symptomatic stages of COVID-19, preventing hospitalization. (4) Conclusions: Factors such as the significant impact on elderly people, the public health organization prevalently state-owned and represented mainly by hospitals, and criticism of the home therapy approach toward SARS-CoV-2-infected people, may have concurred in increasing the number of COVID-19 deaths in Italy.

Paracetamol-related intentional drug overdose among young people: a national registry study of characteristics, incidence and trends, 2007-2018. Soc Psychiatry Psychiatr Epidemiol 2021; 56:773-781. [PMID: 33146859 DOI: 10.1007/s00127-020-01981-y] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2020] [Accepted: 10/24/2020] [Indexed: 01/19/2023]
Abstract
PURPOSE Incidence rates of hospital-presenting self-harm are highest in people under 25 years and are reportedly increasing in some countries. Intentional drug overdose (IDO) is the most common self-harm method among young people, with paracetamol the drug most frequently used. This study aimed to describe the characteristics, incidence, and temporal trends in paracetamol-related IDO among young people. METHODS Data from the National Self-Harm Registry Ireland on hospital-presenting self-harm by individuals aged 1024 years during 2007-2018 were examined. Annual IDO rates per 100,000 were calculated by age and gender. Joinpoint regression analyses and incidence rate ratios were used to examine trends in the incidence of paracetamol-related IDO. RESULTS During the study, 10,985 paracetamol-related IDOs were recorded. The incidence of paracetamol-related IDO among young people increased by 9% between 2007 and 2018 (IRR 1.09 95% CI 1.00-1.19), with the highest annual percentage change (APC) in females aged 18-24 years (APC 1.2%). Conversely, rates of paracetamol-related IDO among males aged 18-24 years decreased significantly (APC 1.6%). Between 2013 and 2018, excesses of 386 and 151 paracetamol-related IDOs were observed in females aged 10-17 and 18-24 years, respectively, and 42 excess presentations were observed for males aged 10-17 years. There were 107 fewer presentations than expected for males aged 18-24 years. CONCLUSION The increase in paracetamol-related IDO among specific groups of young people, particularly young females is an issue of growing concern. Interventions targeting IDO among young people are needed, incorporating measures to address the availability of paracetamol and aftercare following IDO.

Abstract
BACKGROUND Paracetamol is frequently used for intentional self-poisoning, especially in the UK, despite pack size restrictions introduced in 1998. Knowing more about paracetamol self-poisoning may identify further approaches to prevention. METHODS We used data from the Multicentre Study of Self-harm in England for 2004-2014 to calculate incidence rates of presentations to Emergency Departments following self-poisoning with pure paracetamol alone. National estimates for England for 2011-2014 were extrapolated using indirect age-standardised rates. The characteristics of individuals taking paracetamol overdoses and the size of the overdoses were investigated. RESULTS A third of 54,863 intentional overdoses presenting to the five Emergency Departments involved paracetamol without other drugs (N = 18,011), taken by 13,171 individuals (63.4% female). The proportion of paracetamol self-poisonings was similar in the three centres. Extrapolation suggested there were approximately 50,000 paracetamol overdoses in England annually during 2011-2014. Females had higher rates of paracetamol overdose than males. Males and older individuals took larger overdoses. Nearly a quarter of individuals (24.2%) consumed more than 32 tablets. Alcohol was involved in 53.7% of paracetamol overdoses. LIMITATIONS Data were collected in three centres with predominantly urban populations. Extrapolation from local to national rates should be interpreted with caution. CONCLUSIONS Paracetamol overdose remains a major problem in the UK. It is more common in females and younger patients, but males and older patients consume larger overdoses. Consideration should be given to further restriction in pack sizes and sources of sales, in keeping with those of several other European countries.

Abstract
Acetaminophen (APAP) is a widely used analgesic and antipyretic. It is safe at normal treatment doses; however, APAP overdose is a major cause of acute liver and kidney failure. A variety of methods to reduce the damage caused by APAP overdose have previously been evaluated. The protein-rich seaweed Pyropia yezoensis has antioxidant, antitumor and anti-inflammatory activities, and protects against cytotoxicity. However, little is known regarding the protective effects of P. yezoensis peptide against APAP-induced hepatotoxicity. The present study investigated the ability of P. yezoensis peptide (PYP1-4) to ameliorate the damage caused by APAP-induced hepatotoxicity using HepG2 as the model cell line in addition to the signaling pathways involved. Briefly, cell viability, nitric oxide, reactive oxygen species and apoptosis assays were performed in conjunction with western blot analysis and reverse transcription-quantitative PCR. First, the present study revealed the minimum toxic concentration of APAP (15 mM) and the resting concentration of PYP1-4 (0–500 ng/ml). Administration of PYP1-4 to APAP-induced cells decreased the nitric oxide and reactive oxygen species levels, and restored the levels of antioxidant-associated proteins (catalase, heme oxygenase 1, superoxide dismutase 2 and quinone oxidoreductase 1). PYP1-4 increased the translocation of nuclear factor, erythroid 2 like 2 to the nucleus and the activities of glycogen synthase kinase-3β, Akt and AMP-activated protein kinase. In addition, APAP induced apoptosis; however, PYP1-4 inhibited apoptosis by modulating the levels of pro-apoptotic markers (Bad), anti-apoptotic markers (Bcl-2 and BH3 interacting domain death agonist), caspases and poly (ADP-ribose) polymerase 1. Subsequently, the insulin-like growth factor 1 receptor signaling pathway was investigated to determine whether PYP1-4 treatment restored the levels of cell growth-associated factors during APAP-induced hepatotoxicity. PYP1-4 treatment impacted the levels of components of the insulin receptor substrate 1/PI3K/Akt and Ras/Raf/ERK signaling pathways, and promoted cell survival. Therefore, the P. yezoensis peptide PYP1-4 may be useful for preventing APAP-induced hepatotoxicity.

Abstract
OBJECTIVES Acetaminophen overdoses result in nearly 500 deaths annually and a much larger number of hospitalizations. Suicidal overdoses are exceeded in number in the United States by unintentional overdoses. We evaluated clinical, demographic and psychosocial factors among unintentional and intentional overdose patients whose acetaminophen (APAP) toxicity had resulted in acute liver failure. We hypothesized that APAP overdose patients would be more likely to suffer from behavioral health issues and display higher impulsivity scores than the general population. METHODS Within 4days of admission and initial recovery of alertness, we administered a detailed questionnaire that included questions on APAP intake (e.g., dose taken, intent, other substances ingested), the Mini International Neuropsychiatric Interview modules on depression, alcohol use, substance use, and pain disorders and The Barratt Impulsiveness Scale-11. RESULTS The group included 44 intentional (single time point ingestions with the intent to self-harm) and 51 unintentional (multiple time point ingestions to manage pain or other condition) APAP patients enrolled in the Acute Liver Failure Study Group registry between 2007 and 2013. Both groups were characterized by similar frequencies of chronic pain, depressive symptoms at time of ingestion and alcohol and substance use disorders, all at higher rates than the general population. Overall, APAP patients scored higher than the general population for Non-planning aspects of impulsivity, with no apparent differences between other impulsivity scores or between intentional and unintentional APAP patients. CONCLUSIONS Depression, mismanagement of problematic chronic pain, frequent substance abuse, and increased impulsivity appear to provide the substrate for many APAP overdoses.

Abstract
PURPOSE Suicide attempts by adolescents most commonly involve the overdose of medications. To date, there has been little information on the over-the-counter or prescription medicines that adolescents ingest for self-harm. Identification of medications chosen in suicide attempts may help guide anticipatory guidance to parents by primary care providers and Poison Centers in prevention programs. METHODS This was a retrospective observational study using the American Association of Poison Control Center's National Poison Data System. Data were collected on patients aged 13-19 years old at the time of their substance ingestion, between the years 2004 and 2013 and that were coded as reason for ingestion of "intentional-suspected suicide." RESULTS During the 10-year study period, there were 390,560 poison center calls for intentional-suspected suicide in the United States between 2004 and 2013, accounting for 80.3% of all "intentional" ingestion calls in the adolescent population. Over the entire age range, the most common substance ingested included acetaminophen (10.9%), ibuprofen (9%), selective serotonin reuptake inhibitors (7.7%), atypical antipsychotic (6%), and antihistamines (5%). The most common medications coded as resulting in major clinical effects or death were antidepressants and atypical antipsychotics. CONCLUSIONS Adolescent ingestion choices for suicide attempts have remained relatively consistent over the past 10 years. However, there was a recent decrease in selective serotonin reuptake inhibitor ingestions. The most common medications used in an overdose attempt were ibuprofen and acetaminophen. Further preventative efforts are needed in this at-risk population from multiple providers at various levels.

Abstract
Acetaminophen (APAP) is a widely used analgesic and antipyretic drug. Generally, the therapeutic dose of APAP is clinically safe, however, high doses of APAP can cause acute liver and kidney injury. Therefore, the majority of previous studies have focussed on elucidating the mechanisms of APAP-induced hepatotoxicity and nephrotoxicity, in addition to examining ways to treat these conditions in clinical cases. However, few studies have reported APAP-induced intoxication in human stem cells. Stem cells are important in cell proliferation, differentiation and repair during human development, particularly during fetal and child development. At present, whether APAP causes cytotoxic effects in human stem cells remains to be elucidated, therefore, the present study aimed to investigate the cellular effects of APAP treatment in human stem cells. The results of the present study revealed that high-dose APAP induced more marked cytotoxic effects in human mesenchymal stem cells (hMSCs) than in renal tubular cells. In addition, increased levels of hydrogen peroxide (H2O2), phosphorylation of c-Jun N-terminal kinase and p38, and activation of caspase-9/-3 cascade were observed in the APAP-treated hMSCs. By contrast, antioxidants, including vitamin C reduced APAP-induced augmentations in H2O2 levels, but did not inhibit the APAP-induced cytotoxic effects in the hMSCs. These results suggested that high doses of APAP may cause serious damage towards hMSCs.

Abstract
Acetaminophen (APAP), is a safe analgesic and antipyretic drug at therapeutic dose, and is widely used in the clinic. However, high doses of APAP can induce hepatotoxicity and nephrotoxicity. Most studies have focused on high‑dose APAP‑induced acute liver and kidney injury. So far, few studies have investigated the effects of the therapeutic dose (1/10 of the high dose) or of the low dose (1/100 of the high dose) of APAP on the cells. The aim of this study was to investigate the cellular effects of therapeutic- or low‑dose APAP treatment on hepatoma cells and kidney fibroblasts. As expected, high‑dose APAP treatment inhibited while therapeutic and low‑dose treatment did not inhibit cell survival of kidney tubular epithelial cells. In addition, therapeutic-dose treatment induced an increase in the H2O2 level, activated the caspase‑9/‑3 cascade, and induced cell apoptosis of hepatoma cells. Notably, APAP promoted fibroblast proliferation, even at low doses. This study demonstrates that different cellular effects are exerted upon treatment with different APAP concentrations. Our results indicate that treatment with the therapeutic dose of APAP may exert an antitumor activity on hepatoma, while low‑dose treatment may be harmful for patients with fibrosis, since it may cause proliferation of fibroblasts.

Abstract
OBJECTIVES To investigate the impact of narrative verdicts on suicide statistics among 10-19-year-olds; to identify the number and rate of suicide and accidental deaths, particularly in 10-14-year-olds. DESIGN National cohort study. SETTING England and Wales. METHODS Mid-year population estimates from the Office for National Statistics (ONS) were used to calculate rates per 100,000 population for suicide (undetermined and suicide verdicts) and accidental deaths (poisoning, hanging) for those aged 10-14 and 15-19. Trends in rates over time (2001-2010) were investigated using Poisson regression. Interaction tests were carried out to determine differences in trends between the two time periods (2001-2005 and 2006-2010). RESULTS There were 1523 suicides (2.25/100,000). Suicide rates were highest in those aged 15-19 years (4.04/100,000) and in males (3.14/100,000). Between 2001 and 2010, rates significantly decreased among those aged 15-19 years (incidence rate-ratio (IRR): 0.95; 95% CI 0.93 to 0.97), with no change in rates of accidental deaths (IRR: 1.01, 95% CI 0.95 to 1.07). However, there was a significant interaction between the two time periods for accidental poisonings (2001-2005: IRR: 0.79 (95% CI 0.69 to 0.91); 2006-2010: IRR: 1.01 (95% CI 0.89 to 1.15), interaction p=0.012) and accidental hangings (2001-2005: IRR: 0.93 (95% CI 0.76 to 1.14); 2006-2010: IRR: 1.25 (95% CI 1.04 to 1.49), interaction=0.01) Undetermined deaths significantly decreased among females aged 15-19 yeras (IRR: 0.93; 95% CI 0.88 to 0.98). There were no significant trends among 10-14-year-olds. CONCLUSIONS Rates of suicide are higher among older adolescents and males. There was a significant fall in suicide rates in males aged 15-19 years that was not accounted for by changes in rates of accidental death. The absence of a significant trend in suicide or accidental deaths in those aged 10-14 years may have been the result of small numbers. However, monitoring should continue to identify longitudinal trends in all young people.

Abstract
ObjectivesTo carry out a programme of linked research studies aimed at improving the management of self-harm, reducing the incidence of suicide and providing reliable data to evaluate the impact of theNational Suicide Prevention Strategy for England(2002).MethodsThere were four research streams: (1) we studied inquest records from 12 coroners and Ministry of Justice data to assess the accuracy of official suicide statistics; (2) we used Office for National Statistics mortality statistics, data from the Multicentre Study of Self-harm in England, national liver unit data, prescription data and patient interviews to assess (a) the impact of paracetamol (acetaminophen) pack size restrictions (1998), (b) the impact of withdrawal of co-proxamol in 2007 and (c) the relative toxicity in overdose of commonly used antidepressants; (3) we carried out 3-month audits of self-harm management in 32 hospitals to investigate variations between hospitals and the impact of management on repeat self-harm; and (4) we developed and piloted letter-based contact interventions aimed at reducing self-harm.Key findings(1) Between 1990 and 2005, the proportion of researcher-defined suicides given a verdict of suicide by the 12 coroners studied decreased by almost 7%, largely because of the increased use of misadventure/accident verdicts for deaths thought, on clinical review, to be suicides. Use of narrative verdicts increased markedly. Coroners who gave more narrative verdicts also gave fewer suicide verdicts, and geographical variations in the use of narrative verdicts appeared to distort reliable assessment of small-area differences in suicide rates. 2(a) UK legislation to reduce pack sizes of paracetamol was followed by a 43% reduction in number of deaths and a 61% reduction in registrations for liver transplantation over the next 11 years. Paracetamol overdoses were often impulsive and some were influenced by media (including the internet); sales outlets appeared mostly to be adhering to sales guidance. Smaller pack sizes of paracetamol for sale in Ireland compared with England did not result in a smaller number of tablets being taken in overdose. There was no clear evidence of an effect of the legislation on prescribing of non-steroidal anti-inflammatory drugs, nor on resulting gastrointestinal bleeds. 2(b) Withdrawal of co-proxamol from use in the UK resulted in approximately 600 fewer deaths than predicted between 2005 and 2010 based on previous trends, with no evidence of substitution by poisoning with other analgesics. 2(c) Of the tricyclic antidepressants, dosulepin and doxepin had the greatest toxicity. Citalopram was more toxic than other selective serotonin reuptake inhibitors. (3) There was marked variation between hospitals in the management of self-harm; effects of this variation on patient outcomes were unclear, although psychosocial assessment may have been associated with reduced repetition. Levels of specialist assessment remained static between 2001–2 and 2010–11, but service quality appeared to improve. (4) Findings of two pilot randomised controlled trials suggested that, although it would be feasible to scale up these interventions to full trials, these interventions might have low generalisability and be of limited benefit to patients.ConclusionWithin the context of the strengths and limitations of the individual studies, this research programme has made significant additions to the evidence base related to suicide and self-harm prevention in the UK.Study registrationA pilot study of a contact and information based intervention to reduce repeat self-harm; ISRCTN65171515.FundingThe National Institute for Health Research Programme Grants for Applied Research programme.

Abstract
AIM Paracetamol (acetaminophen) is a common cause of liver failure due to overdose. Legislation introduced in the UK in 1998 to limit pack sizes of paracetamol has had limited impact on the overall number and severity of paracetamol overdoses. This may be because people have large amounts of paracetamol stored at home, but no previous studies have explored this question. METHODS Individuals who regularly take part in market research surveys were invited to take part in an Internet survey. They were asked to supply demographic details, the frequency with which they use paracetamol and ibuprofen, and details of the amount and location of these drugs that they possessed. RESULTS The mean age of respondents was 43.3 years (standard deviation 14.5 years), and 49.9% were female. People with both ibuprofen and paracetamol tended to have more packs and tablets of paracetamol (P < 0.001) and over a third had 32 or more paracetamol tablets. The most common pack size was 16 tablet packs (44.8% of all packs), which accounted for 39.4% of tablets. The most common site of paracetamol storage in the home was the kitchen (63.8% of people, 95% confidence interval 60.7, 66.7). CONCLUSION This study suggests that pack size legislation in the UK has had limited effect on the amount of paracetamol that individuals have access to in the home. This may explain, at least in part, the limited impact of the pack size legislation on paracetamol overdoses in the UK.

Abstract
OBJECTIVE To assess the long term effect of United Kingdom legislation introduced in September 1998 to restrict pack sizes of paracetamol on deaths from paracetamol poisoning and liver unit activity. DESIGN Interrupted time series analyses to assess mean quarterly changes from October 1998 to the end of 2009 relative to projected deaths without the legislation based on pre-legislation trends. SETTING Mortality (1993-2009) and liver unit activity (1995-2009) in England and Wales, using information from the Office for National Statistics and NHS Blood and Transplant, respectively. PARTICIPANTS Residents of England and Wales. MAIN OUTCOME MEASURES Suicide, deaths of undetermined intent, and accidental poisoning deaths involving single drug ingestion of paracetamol and paracetamol compounds in people aged 10 years and over, and liver unit registrations and transplantations for paracetamol induced hepatotoxicity. RESULTS Compared with the pre-legislation level, following the legislation there was an estimated average reduction of 17 (95% confidence interval -25 to -9) deaths per quarter in England and Wales involving paracetamol alone (with or without alcohol) that received suicide or undetermined verdicts. This decrease represented a 43% reduction or an estimated 765 fewer deaths over the 11¼ years after the legislation. A similar effect was found when accidental poisoning deaths were included, and when a conservative method of analysis was used. This decrease was largely unaltered after controlling for a non-significant reduction in deaths involving other methods of poisoning and also suicides by all methods. There was a 61% reduction in registrations for liver transplantation for paracetamol induced hepatotoxicity (-11 (-20 to -1) registrations per quarter). But no reduction was seen in actual transplantations (-3 (-12 to 6)), nor in registrations after a conservative method of analysis was used. CONCLUSIONS UK legislation to reduce pack sizes of paracetamol was followed by significant reductions in deaths due to paracetamol overdose, with some indication of fewer registrations for transplantation at liver units during the 11 years after the legislation. The continuing toll of deaths suggests, however, that further preventive measures should be sought.

Abstract
There is a growing body of evidence to suggest that only a minority of young people experiencing suicidal thoughts or self-harm present to any health services. This is of concern given that young people with suicidal thoughts or self-harm often require treatment for mental illness as well as to reduce their risk of completed suicide. We reviewed previously published international community epidemiological studies examining help-seeking for suicidal thoughts or self-harm in young people up to the age of 26. The studies confirm that the majority of these young people do not seek professional help, and this includes seeking medical help after an overdose. The majority of young people studied do, however, seek help from social networks that most commonly are peers. Factors influencing and barriers to help-seeking are discussed and highlight a need for further research into the role that peers and family play in the help-seeking process for young people with suicidal thoughts or self-harm.
