ABSTRACT The aims of this study were to describe and compare the epidemiology of acute poisoning hospital discharges in women of reproductive age and during pregnancy (aged between 15 and 44) to include the incidence rate, risk factors, substances involved, rates of intentional versus unintentional poisonings, and in pregnant women, distribution over trimesters. Through a cohort study design, the California patient discharge dataset and linked vital statistics-patient discharge database were used to identify cases of acute poisoning hospital discharges from 2000 to 2004 among women of reproductive age and among pregnant women. Odds ratios (OR) were calculated to identify risk factors using logistic regression. Of 4,436,019 hospital discharges in women of reproductive age, 1% were for an acute poisoning (115.3/100,000 person-years). There were 2,285,540 deliveries and 833 hospital discharges for an acute poisoning during pregnancy (48.6/100,000 person-years). Pregnancy was associated with a lower risk of acute poisoning (OR = 0.89, P = 0.0007). Poisonings were greatest among young black women regardless of pregnancy status and among those with substance abuse or mental health problems. Analgesic and psychiatric medications were most commonly implicated. The majority of poisonings among women of reproductive age (69.6%) and among pregnant women (61.6%) were self-inflicted. Efforts to reduce acute poisonings among women of reproductive age should include education regarding the use of over-the-counter medications and interventions to reduce self-inflicted harm.

    ABSTRACT: Acetaminophen (APAP)/paracetamol is one of the most commonly used over-the-counter drugs taken worldwide for treatment of pain and fever. Although considered as safe when taken in recommended doses not higher than 4 g/day, APAP overdose is currently the most important cause of acute liver failure (ALF). ALF may require liver transplantation and can be fatal. The reasons for APAP-related ALF are mostly intentional (suicidal) or unintentional overdose. However, results from large scale epidemiological studies provide increasing evidence for second generation effects of APAP, even when taken in pharmacological doses. Most strikingly, APAP medication during pregnancy has been associated with health problems including neurodevelopmental and behavioral disorders such as attention deficit hyperactivity disorder and increase in the risk of wheezing and incidence of asthma among offspring. This article reviews the epidemiological findings and aims to shed light into the molecular and cellular mechanisms responsible for APAP-mediated prenatal risk for asthma.

    ABSTRACT: The aim of this study is to investigate and analyse pregnant women who were admitted to our emergency service due to acute poisoning. All cases were retrospectively collected from our computer records and emergency record book between 01.01.2006 and 01.01.2010; the registration data on age, gravidity, gestational week, whether the poisoning was deliberate or accidental, causative agent, admission time, treatment results and mortality outcome were collected and analyzed. Eighty eight women admitted with acute poisoning were known to be pregnant and the poisoning was accidental in 23% of the cases, while 77% were suicidal intoxications. 74% of patients were in the 21-34 age group. Accidental intoxications were due to carbon monoxide, foods and cleaning products. 75.4% of the suicidal poisonings were caused by medical drugs, with analgesics, multiple drugs and psychiatric drugs being the top culprits and accounted for 53%, 31% and 16% of drug poisonings respectively. In terms of gestational week, 47.4% of suicidal poisonings were within the first trimester and the relationship between suicidal attempt and gestational week was found to be statistically significant (p<0.015). However, the relationship between gravidity and the rate of suicidal attempts was not statistically significant (p=0.214). All patients were followed up and treated in the emergency service and no mortality was observed in the study. Most cases of acute poisonings during pregnancy were suicidal. Pregnant women attempted suicide mostly within the first trimester of gestation. The most common agents used for suicidal attempt were medical drugs.

    ABSTRACT: Introduction: Perinatal suicidality (i.e., thoughts of death, suicide attempts, or self-harm during the period immediately before and up to 12 months after the birth of a child) is a significant public health concern. Few investigations have examined the patients' own views and experiences of maternal suicidal ideation. Methods: Between April and October 2010, researchers identified 14 patient participants at a single university-based medical center for a follow-up, semi-structured interview if they screened positive for suicidal ideation on the Patient Health Questionnaire-9 (PHQ-9) short form. In-depth interviews followed a semi-structured interview guide. Researchers transcribed all interviews verbatim and analyzed transcripts using thematic network analysis. Results: Participants described the experience of suicidality during pregnancy as related to somatic symptoms, past diagnoses, infanticide, family psychiatric history (e.g., completed suicides and family member attempts), and pregnancy complications. The network of themes included the perinatal experience, patient descriptions of changes in mood symptoms, illustrations of situational coping, and reported mental health service use. Implications: The interview themes suggested that in this small sample, pregnancy represented a critical time period to screen for suicide and to establish treatment for the mothers in the study. These findings may assist health care professionals in the development of interventions designed to identify, assess, and prevent suicidality among perinatal women.
