Age and gender differences in the use of various poisoning methods for deliberate parasuicide cases admitted to loghman hospital in Tehran (2000-2004)

Clinical course and demographic insights into suicide by self-poisoning: patterns of substance use and socio-economic factors

PURPOSE

To analyze whether sociodemographic characteristics influence the substance choice and preclinical and clinical course of suicidal poisoning.

METHODS

This was a retrospective single-center study in patients hospitalized due to suicidal poisoning and who received at least one psychiatric exploration during their inpatient stay. Patients' sociodemographic, anamnestic, preclinical, and clinical parameters were analyzed with respect to sex and age.

RESULTS

1090 patients were included, 727 (67%) were females, median age was 39 years (min-max: 13-91) with 603 (55%) aged 18-44 years. 595 patients (54.8%) ingested a single substance for self-poisoning, 609 (59.5%) used their own long-term medication. Comparing to males, females preferred antidepressants (n = 223, 30.7%, vs n = 85, 23.4%; p = 0.013) and benzodiazepines (n = 202, 27.8%, vs n = 65, 17.9%; p < 0.001); males more often used cardiovascular drugs (n = 33, 9.1%, vs n = 34, 4.7%; p = 0.005) and carbon monoxide (n = 18, 5.0%, vs n = 2, 0.3%; p < 0.001). Use of Z-drugs (n = 1, 1.7%, to n = 37, 33.3%; p < 0.001) and benzodiazepines (n = 4, 6.9%, to n = 33, 29.7%; p = 0.003) increased with age (< 18 to > 64 years), while use of non-opioid analgesics (n = 23, 39.7%, to n = 20, 18.0%; p < 0.001) decreased. Average dose of substance in patients > 64 years was 12.9 ± 18.4 times higher than recommended maximum daily dose (compared to 8.7 ± 15.2 higher in those aged < 18 years; p < 0.001). Males more often required intensive care (n = 150, 41.3%, vs n = 205 females, 28.2%; p < 0.001).

CONCLUSION

These results underline the complexity of (para-)suicidal poisonings and identify potential measures for their prevention, such as restricting access and better oversight over the use of certain substances.

Age- and gender-specific acute poisoning with drugs and medications affecting nervous system

BACKGROUND

We investigated acute poisonings resulting from medications affecting the nervous system and illicit substances at Loghman Hakim Hospital in Tehran.

METHODS

We retrospectively reviewed patient records at Iran's largest tertiary toxicology referral center between January 2010 and December 2015. We analyzed the prevalence, trend, age and gender distribution of acute poisoning caused by nervous system agents.

RESULTS

The present study included 16,657 (57.27%) males and 12,426 (42.73%) females, resulting in 29,083 patients. The median age of men and women was 29 and 26 years, respectively (p < 0.0001). There were 12,071 (72.47%) men and 10,326 (83.10%) women under the age of 40 (p < 0.001). Most cases were intentional (69.38% in men and 79.00% in women, p < 0.001) and 44.10% had a history of poisoning. The proportions of men and women varied significantly between different age groups and nervous system agents. For women, the most common agent was alprazolam, whereas for men, methadone. The overall trend of acute poisoning with drug used in addictive disorders, opioids and alcohol was increasing but decreasing with benzodiazepines and antidepressants. Acute poisoning by nervous system agents led to more deaths in men (1.95% vs. 0.56%; p < 0.001).

CONCLUSIONS

Methadone intoxication was common especially among young men and most of these intoxications were intentional. Women and men aged 20-29 most frequently suffer poisoning from alprazolam and clonazepam, respectively. Women over 60 and men over 30 used opium. Illicit drugs caused more than half of the deaths, and opium dominated. This study may create awareness and develop educational and preventive gender and age-specific local programs.

Lessons to be learned: identifying high-risk medication and circumstances in patients at risk for suicidal self-poisoning

Background

Although the total number of suicides decreased since the beginning of the 1980s, the number of suicide-related behaviors using self-intoxication increased. Therefore, research on the characteristics of individuals committing self-intoxication becomes of growing importance for risk assessments and the development of preventive measures.

Methods

In this prospective, observational, monocentric cohort study, all incoming calls at our Poisons Control Centre reporting suicide-related behaviors through self-intoxication, were analyzed via a standardized questionnaire over 12 months. Both univariate and bivariate analyses were performed.

Results

1238 cases of deliberate intoxication were included in the study. The majority of cases occurred in the age group between 18 and 44 (n = 607/49%), two-thirds were female (n = 817/66%). The main substances used were antidepressants (n = 420/34%), peripheral analgesics (n = 322/26%) and neuroleptics (n = 282/23%). The majority of patients ingested substances from their prescribed medication (n = 640/82%) with the highest proportion in those aged over 64 years (n = 72/113; 91%, p < 0.001). Substance use was reported for the minority of patients (n = 175/23%). For 704 cases (79%), a psychiatric disorder was documented. Factors associated with recurrent suicide-related behaviors were an underlying psychiatric disorder (OR = 6.2; 95% CI 3.8–10.4), substance use (OR = 2.4; 95% CI 1.5–3.8), and ingestion of neuroleptics (OR = 2.1, 95% CI 1.4–3.0) or antidepressants (OR = 1.6; 95% CI 1.2–2.3).

Conclusion

This study might contribute to identifying individuals with an increased risk of suicide-related behaviors by deliberate intoxication and to developing preventive strategies for future suicide attempt(s).

Self-poisoning in the acute care medicine 2005-2012

OBJECTIVE

To describe the trend of acute self-poisoning in the emergency and intensive care.

METHODS

Electronic charts of adults who presented to the emergency department of the University Hospital Leipzig with self-poisoning following a suicide attempt (suicide group), intoxication (intoxication group), drug overdose for relief of pain or discomfort (drug overdose group) between 2005 and 2012 were analyzed.

RESULTS

3533 adults (62.6% males) were identified, with the yearly admissions increasing from 305 in 2005 to 624 in 2012. The admission rate in relation to the total emergency department admissions also increased, from 1.2% in 2005 to 1.9% in 2012. 31.7% of the patients were younger than 25 years. The reasons for self-poisoning were suicide attempt (18.1%), intoxication (76.8%) and drug overdose (2.9%). The reason could not be clearly classified in 80 patients. Psychotropic drugs were used in 71.6% of suicide attempts, while alcohol was the sole cause of intoxication in 80.1% of cases in the intoxication group. Self-poisoning using at least two substances was observed in 52.0% of the suicide attempts, 10.3% of those with intoxication and 29.7% of those with drug overdose. While alcohol remains the most common cause of intoxication, there was a drastic increase in the consumption of cannabinoids, Crystal Meth and gamma-hydroxybutyrate in the years 2011 and 2012. ICU admission was necessary in 16.6% of the cases. There were 22 deaths (0.6% of the study population), of whom 15 were in the suicide group (2.3%), four (0.15%) in the intoxication group, and three in the not clearly classified group (3.8%).

CONCLUSION

Acute self-poisoning is an increasing medical issue. Psychotropic drugs remain the most common means of suicide attempt. Although alcohol intoxication is very frequent, intake of illicit drugs as the cause of emergency admission is increasing.

Environmental and population studies concerning exposure to pesticides in iran: a comprehensive review

Pesticides are widely used in Iranian agriculture and this has made a major toxicological concern among health professionals. The objective of this study is to explore national data about pesticides toxicity. All relevant databases such as Google Scholar, PubMed, and Scopus in a time period of 1960 to 2012 were searched for the keywords “Pesticides, Iran, Environment, and Population studies”. A total of 57 studies were found relevant and then included into study. Almost all non-experimental studies carried out in Iran were classified into two main categories of residue assessment in different samples and toxic effects on human. Depending on the dose and duration of exposure, toxic effects of pesticides have been studied in two classifications including acute toxicity or acute poisoning and chronic toxicity. High extent of pesticides have been used during the past decade in Iran while no enough proper studies were done to explore their possible toxic effects in the environment and the people.

An epidemiological survey of the suicide incidence trends in the southwest iran: 2004-2009

BACKGROUND

Elimination of suicide attempts is impossible, but they can be reduced dramatically by an organized planning. The present study aimed to survey the suicide trends in Fars province (Iran), during 2004-2009 to better understand the prevalence and status of suicide.

METHODS

This survey was a cross-sectional study. The demographic data were collected from the civil status registry between 2004 and 2009. Suicide and suicide attempt data were collected of three sources including the affiliated hospitals of Shiraz University of Medical Sciences, mortality data of Vice Chancellery of Health in Fars province and data from forensic medicine. Then, they were analyzed by Excel and SPSS. Chi-square and regression analyses were used for data analysis.

RESULTS

During the study, 10671 people attempted suicide, of which 5697 (53%) were women and 4974 (47%) were men. Among them, 1047 people (9.8%) died, of which 363 (34%) were women and 679 (64%) were men. There was a significant relationship between gender and fatal suicide. The mean suicide attempt for both genders was 53 per 100,000 and 49, 57 for men and women, respectively. The trends in the incidence of Suicidal attempts were decreasing.

CONCLUSION

Without implementing effective preventive measures, the health care system in Iran will face a further burden of fatal suicides among young people. Therefore; enhancing the primary health care and specialized mental health services for those with unsuccessful suicide attempts can effectively reduce the burden of suicide.

Reinventing intention: 'self-harm' and the 'cry for help' in postwar Britain

PURPOSE OF REVIEW

To sketch out how contemporary Anglophone literature on self-damaging behaviour negotiates serious conceptual difficulties around intention, and to demonstrate (in the British context) how the large-scale emergence of this type of behaviour is made possible by new forms of psychological provision at district general hospitals.

RECENT FINDINGS

In the past decade, there has been increasing public awareness of 'self-harm'. Despite the view that 'self-harm' has always existed, the British roots of the current 'epidemic' can be traced to changes in the organization of mental healthcare in the postwar period. These changes make possible new understandings of the story behind physical injuries, and allow these readings to be aggregated and projected onto a national, epidemic scale.

SUMMARY

The increasing provision of psychiatric expertise in general hospitals makes possible new interpretations of self-injury - as psychosocial communication, or affect self-regulation - and creates the phenomenon of 'self-harm' as we understand it today.

General Health Status in a Cohort of Iranian Patients with Intentional Self-poisoning: A Preventive Approach

Background:

Prevention of suicide is one of the most important issues of community medicine in the world. Because of high accessibility of people to different drugs in our society, one of the easiest ways of suicide is intentional self-poisoning. In this study, demographic factors and health status of the patients with intentional self-poisoning were evaluated.

Methods:

A cross-sectional study was conducted in the poisoning referral center on 384 patients aged 15–40 years who committed intentional self-poisoning. Information was gathered using two questionnaires about demographic characteristics and the general health status of the patients.

Results:

70.5% of the patients had easy accessibility to drugs. Most of the patients were women (62.5%) and single (51%). History of psychological disease was demonstrated in 82.5% of patients. In terms of general health status, the most common problems were social dysfunction (97.57%) and depression (88.9%).

Conclusion:

Easy accessibility to drugs and psychological problems may increase the risk of intentional self-poisoning. Being religious and the consequent hopefulness may have a positive protecting effect for the prevention of intentional self-poisoning.
