[Attempted suicide by firearms: a retrospective study of 161 cases]

Are Facial Gunshot Wounds More Fatal When They Are Self-Inflicted or Other-Inflicted?

Study Design

This was a retrospective cohort study of the 2014 Nationwide Emergency Department Sample (NEDS).

Objective

Intraoral and submental projectile entry points may be less fatal than other facial entry points due to the indirect access to the intracranial structures and the protection offered by the intervening maxillofacial complex. Because intraoral and submental trajectories are almost always present in the setting of attempted suicide, this study sought to determine if intent (self-harm versus other-harm) influenced mortality in facial gunshot wound (GSW) patients.

Methods

All patients with a diagnosis of a facial fracture secondary to firearm injury were included in the study sample. The primary predictor was self-harm. Secondary predictors were derived from patient, injury, and hospitalization characteristics. The study outcome was death. Univariate time to event analyses were conducted for all study predictors. A multivariate regression model for mortality was created using all relevant predictors.

Results

The final sample included 668 facial GSW injuries, of which 19.3% were attributed to self-harm. Self-inflicted GSWs were more likely to involve the mandible (58.9 vs 46.0%, P < 0.01), ZMC/maxilla (47.3 vs 32.5%, P < 0.01), and intracranial cavity (48.1 vs 22.6%, P < 0.01). The overall mortality rate was 7.3%, and the mean time to death was 2.2 days. After controlling for pertinent covariates, the risk of mortality was independently decreased with mandibular injury (HR = 0.36, P = 0.03). However, mortality was increased by self-harm intent (HR = 3.94, P < 0.01) and intracranial involvement (HR = 11.24, P < 0.01).

Conclusions

Consistent with a pattern of intraoral and submental entry points, self-inflicted facial GSWs demonstrated higher rates of mandibular injury. Despite this finding, self-harm injuries still carried a higher incidence of intracranial injury and a greater independent risk of mortality. Our results refute any notion that the mechanism and trajectory of self-inflicted GSWs is less fatal.

Handcrafted firearm suicide: About the unusual use of a mole gun

The body of a man was found in a workshop at the back of his home, a metal pipe embedded in his chest. In the immediate vicinity of the body, among various tools, was a machine containing a holster hit of lead shot evoking a mole-trap-type "taupe gun" (mole gun). The findings at the scene and the presence of a metal tube, sinkers, and a flock in the chest are in favour of the use of a homemade firearm. The autopsy and CT scan revealed atypical ballistic thoracic trauma responsible for a dilaceration of both the heart and thoracic aorta that caused the death. The autopsy also found a contused wound at the back of the skull without intracranial lesion, which may be due to the fall of the victim after the thoracic trauma. There is no other traumatic lesion and in particular no lesion of seizure, constraint, or defense. Toxicological analyses revealed the presence of alcoholic impregnation at the time of death. These findings, confronted with the expertise of a balistician, made it possible to understand how the victim used a mole gun to cause these lesions. A metal tube was used as a cannon to aim more surely at the heart but also as a means of triggering the propulsion mechanism of the trap without having to stretch out the arm. The tube, thinner than the barrel, had disengaged from its tip to be embedded with the lead shot in the chest of the victim.

[Suicidal ideas in psychiatric emergency departments: prospective study comparing self- and hetero-assessment]

OBJECTIVE

Many suicide victims had contacts with an emergency department before their attempt. We aimed to determine whether patients coming to a psychiatric emergency department were well assessed concerning their suicidal risk, and to test an easy to fill in scale rapidly assessing suicidal risk.

METHOD

We conducted a descriptive epidemiological survey in Marseille. The source population was all patients admitted to the psychiatric emergency department. We used a booklet containing three questionnaires for "nurse", "psychiatrist" and "patient". We estimated the suicidal risk using both a visual analogue scale (similar for patients and caregivers), and validated scales on self-assessment (scale of suicidality SBQ-R and the Beck Hopelessness Scale).

RESULTS AND DISCUSSION

The questionnaire results have shown that people who visited a psychiatric emergency department presented a significant suicidal risk on several criteria: socio-demographic criteria (social isolation, low level of education, low number of people with a job), psychiatric history (rate of pre-existing psychiatric disorders significantly higher than in the general population, high proportions of family and personal history of suicide attempts, psychiatric hospitalizations, and people with a psychiatrist). Six percent of patients claimed to have come to an emergency unit for suicidal ideas but they were ten times more with a suicidal risk, according to the SBQ-R score. The suicidal risk self-assessed by patients on our visual analogue scale was well correlated with SBQ-R scale and Beck Hopelessness scale, but was not well correlated with the evaluation of caregivers.

CONCLUSION

Hence, the analog scale we created is easy to use and seems to be a good tool for suicidal risk estimation when it is self-assessed by patients in our study population.

Firearm injuries presenting to a tertiary care hospital of Karachi, Pakistan

Background:

Violence is a public health problem in low and middle income countries. Our study attempted to define the circumstances, risk groups, extent and severity of firearm-related injuries in patients coming to the Aga Khan University Hospital (AKUH) Karachi, Pakistan.

Methods:

This was a retrospective study conducted in the department of Emergency Medicine (EM) at AKUH Karachi, Pakistan. Past medical records of all patients who were injured by firearms and were presented to the AKUH Emergency Department (ED) from June 2002 till May 2007 were reviewed. Data were recorded on the basic demographics of injured, length of hospital stay, body parts injured and the outcome (alive vs. dead).

Results:

Total of 286 patients with firearm injuries were identified. Majority of them were males (92%; n=264). More than half of the patients (63%) were in the age group of 21-40 years. Upon arrival to the hospital 85% (n=243) of patients had Glasgow Coma Scale (GCS)>= 13. The mean injury severity score (ISS) was found to be 6 (SD ±4). The length of hospital stay of patients ranged from 0 to 54 days with a mean of 7 days. Lower limb were the most affected body parts (30%, n=86) followed by abdomen pelvis (27%, n=77). Seven percent (n=21) of the patient who were brought to the hospital were labeled as "deceased on arrival". Most of the injuries were caused during the act of robbery (40%, n=103) in the city.

Conclusions:

Robbery was the most common cause of firearm injuries. Lower limb, abdomen and pelvis were the most affected body regions. Educational efforts, and individual, community and societal approaches are needed to alleviate firearm-related injuries.
