A: Early predictors of hepatic injury after suicide attempt with acetaminophen: To explore the following in a pediatric population with acetaminophen overdose due to suicide attempt: 1) the prevalence of episodes of pre- and in-hospital vomiting and the relationship between the total number of vomiting episodes and hepatic injury, 2) the relevance of the early initiation of N-acetylcysteine (NAC) treatment to hepatic injury, and 3) the presence/absence of illness prior to the suicide attempt and hepatic injury. B: Characteristics, social behaviour, trends and risk factors: 1\. To explore the relationship between children admitted to a paediatric department as a result of suicide attempts with acetaminophen and their parents and friends. 2. To determine the extent to which the children had attempted to speak to their parents or other adults about their problems before their suicide attempts. 3. To determine the prevalence of self-mutilation among children with suicidal behaviour. 4. To examine the reasons for these suicide attempts. C: Establishment of the expression of cytochrome P450 in a pediatric including the age-adjusted activities. Urine samples will be analyzed using an HPLC tandem mass spectrometric method, which we have already established in our lab. There will be categorized three groups for comparison: 1. An age-appropriate background population (approximately 200 patients) 2. Paediatric patients that have been admitted to Rigshospitalet, due to severe hepatic injury (approximately 50 patients) 3. Other pediatric patients admitted to their local hospital because of acetaminophen poisoning (approximately 200 patients) A control urine sample will be analyzed three months after the suicide attempt.

RECRUITINGEarly predictors of hepatic injury
1\) To identify early clinical and biochemical predictors of hepatoxicity in children and adolescents after the ingestion of a single acetaminophen overdose as a part of a suicide attempt e.g. pre-hospital vomiting, in-hospital vomiting, stomach pains, latency time before NAC treatment, illness prior to the suicide attempt. The initial and maximum levels of the following biochemical parameters are registered from the electronic biochemistry files of each patient: gluthathione (GLU), basic phosphatase (BP), INR, ALT, AST, and s-acetaminophen.
Time frame: 2 years
Expression of CYP 1A2 in a pediatric population
The expression of cytochrome P450 in a pediatric population including the age-adjusted activities. Urine samples will be analyzed using an HPLC tandem mass spectrometric method, which we have already established in our lab. There will be categorized three groups for comparison: An age-appropriate background population (approximately 200 patients) Paediatric patients that have been admitted to Rigshospitalet, due to severe hepatic injury (approximately 50 patients) Other pediatric patients admitted to their local hospital because of acetaminophen poisoning (approximately 200 patients) A control urine sample will be analyzed three months after the suicide attempt.
Time frame: 2 years
Characteristics, social behaviour, trends and risk factors
1)The relationship children with suicidal behaviour have with their parents and friends. 2)The prevalence of self-mutilation among children with suicidal behaviour. 3)The purposes and main reasons for suicide attempts among children/adolescents. 4) The extent to which these suicide attempts are planned. 5) The extent of acetaminophen intake.
Time frame: 2 years
