Self-inflicted Stabbings as Nonfatal Suicide Attempts: A Systematic Review and Case Series

BACKGROUND

Suicide by cutting or piercing is a rare and often nonlethal method. Self-stabbings are a subset of these cases, which can lead to significant injuries. Current literature does not adequately summarize the psychiatric characteristics of this population.

OBJECTIVE

To examine the psychiatric presentations of adults with nonfatal self-inflicted stabbing suicide attempts to better inform the evidence-based care provided by the psychiatric consult service.

METHODS

We searched Embase, Ovid MEDLINE, APA Psych INFO, and CINAHL for studies published within the last 15 years. All full-article case reports, case series, cohort studies, and systematic literature reviews in English were included. Studies not specific to adult (>18 years old) patients with self-inflicted stabbing wounds were excluded. Included studies were separated into 2 groups: case reports and cohort studies. Simple summative statistical analyses were performed. The quality of evidence was assessed using a modified version of the Joanna Briggs Institute Critical Appraisal Tools.

RESULTS

Thirty-four case reports, 3 cohort studies, and zero systematic literature reviews met the inclusion and quality assessment criteria. A total of 184 cases of self-stabbing were identified, 66% of which included male patients. The mean age of cohort patients was 44 years. The mean age of case report patients was 47 years. The most common tool for stabbing was a knife. Common stabbing locations included the neck, chest, and abdomen. Commonly reported psychiatric diagnoses included mood disorders and schizophrenia spectrum disorders. Self-stabbing characteristics important to psychiatry were inconsistently reported across studies.

CONCLUSIONS

This literature review found that self-stabbing appears to be a male-preferred method and may be associated with mood disorders. Inconsistent reporting of relevant psychiatric data such as psychiatric diagnosis, previous psychiatric history, suicidal intent, and intoxication is present in our review and is potentially due to a lack of reports from the psychiatric perspective. This limits our understanding of psychiatric issues in adults who made nonfatal self-inflicted stabbing suicide attempts. A further study into the presentations of this population is needed to better understand this distinct group of patients.

Diagnosis and treatment of a penetrating brain injury caused by a welding electrode: A case report

RATIONALE

Penetrating brain injury caused by a welding electrode is a rare occurrence. This type of injury requires careful preoperative assessment and timely treatment measures to avoid secondary damage.

PATIENT CONCERNS

A 55-year-old male patient fell from a height of approximately 5 m during when a welding electrode in his left hand was inadvertently inserted into his brain. The patient had a GCS score of 15 and complaints of dizziness and headache. CT showed an object of metallic density penetrating the skull and entering the brain parenchyma in the frontotemporal region.

DIAGNOSIS

According to the clinical findings and preoperative imaging examination, the diagnosis was open craniocerebral injury with intracranial foreign body and left orbital wall fracture.

INTERVENTION

After definite diagnosis and sufficient preoperative preparation, active surgical treatment was carried out to remove intracranial foreign body. Anti-infection and other symptomatic treatment were given after operation. The signs of infection and changes of vital signs were closely observed.

OUTCOMES

After treatment, no obvious adverse reactions were found and the patient was discharged. No complications such as infection occurred during the follow-up period of 6 months.

LESSONS

In treating patient with a welding electrode penetrating the brain, assessments need to be made preoperatively, the welding electrode needs to be removed in a timely manner, complete hemostasis needs to be achieved during surgery with total repair of the damaged area, and anti-inflammatory treatment needs to be administered postoperatively to achieve good results.

Long-term self-inflicted craniocerebral penetrating injury with a fatal outcome

A case of long-term continual self-inflicted penetrating craniocerebral injury to a 59-year-old man with a fatal outcome is reported. The man suffered from paranoid psychosis and alcohol dependence. Over five months, he continually scalped the skin and subcutaneous tissue of his head with a knife until he perforated the skull and dura mater and injured his brain. He eventually sought medical advice, but died after 10 days of hospitalization despite complex conservative treatment. The immediate cause of death was a combination of central nervous system failure and heart failure. The original case presented is sporadic in the forensic literature due to atypical long-term continual self-harm to the head and brain using a sharp object that resulted in perforation of the skull and a fatal outcome. This case also highlights the importance of autopsy to determine the mechanism of injury and cause of death.

Penetrating intracranial nail-gun injury to the middle cerebral artery: A successful primary repair

BACKGROUND

Penetrating nail-gun injuries to the head are rare, however, the incidence has been gradually rising over the last decade. While there is a large volume of case reports in the literature, there are only a few incidences of cerebrovascular injury. We present a case of a patient with a nail-gun injury to the brain, which compromised the cerebral vasculature. In this article, we present the case, incidence, pathology, and a brief literature review of penetrating nail-gun injuries to highlight the principles of management pertaining to penetration of cerebrovascular structures.

CASE DESCRIPTION

A 26-year-old male presented with a penetrating nail-gun injury to his head. There were no neurological deficits. Initial imaging revealed that the nail had penetrated the cranium and suggested the vasculature to be intact. However, due to the proximity of the nail to the circle of Willis the operative approach was tailored in anticipation of a vascular injury. Intraoperatively removal of the foreign body demonstrated a laceration to the M1 branch of the middle cerebral artery (MCA), which was successfully repaired.

CONCLUSION

To our knowledge, this is the first reported case of a vascular arterial injury to the MCA from a nail-gun injury. It is imperative to have a high clinical suspicion for cerebrovascular compromise in penetrating nail-gun injuries even when conventional imaging suggests otherwise.

Nail injury to the brain obfuscated by a fall from height - homicide or suicide? a case report

Penetrating head injuries caused by unconventional objects such as a nail generate speculation and doubt regarding the manner of infliction. We report a case of a 24-year-old woman alleged to have committed suicide by a fall from height. Autopsy revealed an unprecedented penetrating intracranial injury caused by a nail over the right temporal region, confounding the manner of death. The underlying intersecting pattern of fractures determined the chronological sequence of events. In this paper, we discuss the manner, incidence and pathology of nail injuries to the brain.

Post-traumatic cerebral infarction following low-energy penetrating craniocerebral injury caused by a nail

Post-traumatic cerebral infarction (PTCI) is a secondary insult which causes global cerebral hypoxia or hypoperfusion after traumatic brain injury, and carries a remarkable high mortality rate. PTCI is usually caused by blunt brain injury with gross hematoma and/or brain herniation. Herein, we present the case of a 91-year-old male who had sustained PTCI following a low-energy penetrating craniocerebral injury due to a nail without evidence of hematoma. The patient survived after a decompressive craniectomy, but permanent neurological damage occurred. This is the first case of profound PTCI following a low-energy penetrating craniocerebral nail injury and reminds clinicians of possibility this rare dreadful complication for care of head-injured patients.
