title: Harakiri: a clinical study of deliberate self-stabbing.
abstract: BACKGROUND
  Stabbing is an uncommon method of self-harm that has not been previously described in the psychiatric literature. The aim of this study was to describe the clinical features and management of patients presenting with self-inflicted stab injuries.
  
  
  METHODS
  Case notes of all patients presenting with deliberate self-inflicted injuries during a 2-year period to a teaching general hospital were screened to identify the sample of interest. Clinical data were then collected by means of a detailed case-note study.
  
  
  RESULTS
  Ten patients who deliberately stabbed themselves were identified. The patients fell into two distinct clinical groups: the first consisted mostly of young men with antisocial personalities who were intoxicated at the time of the self-stabbing and who reported ambivalent suicidal intent; the second consisted of psychotic patients, most of whom were actively ill at the time of the self-stabbing, and who reported clear suicidal intent. Patients in the first group were noncompliant with treatment and difficult to engage; those in the second group needed psychiatric hospitalization and often responded to antipsychotic medication.
  
  
  CONCLUSIONS
  Persons who stab themselves tend to fall into two clinical groups that have different diagnoses and management. Distinctions between violent suicidal behavior and self-mutilation are blurred because suicidal intent can be difficult to assess.
