Unusual planned complex suicide committed with a muzzle-loading pistol in combination with subsequent hanging.

In Germany, suicides by firearms are not very common in contrast to deaths by hanging and intoxications. The use of historical muzzle-loading firearms in the context of suicides is a rarity. Contact shots from muzzle loaders cause an unusual wound morphology with extensive soot soiling. We report the case of a 59-year-old man, who committed a planned complex suicide by shooting into his mouth with a replica percussion gun in combination with hanging. The gunshot injury showed strong explosive effects in the oral cavity with fractures of the facial bones and the skull associated with cerebral evisceration (so-called Krönlein shot). Due to the special constellation of the case with hanging immediately after the shot, external bleeding from the head injuries was only moderate. Therefore, the head injuries could be assessed and partially reconstructed already at the scene.

Heridas por proyectil de arma de fuego en cráneo: revisión de la literatura / Firearm projectile wounds on skull: literature review

El trauma craneoencefálico es una de las principales causas de muerte en el mundo, y gran parte de estos se asocian a heridas por arma de fuego en cráneo. Conocer el manejo, las características y fisiopatología de la lesión nos permitirá saber abordar estos casos cuando se presenten a los diferentes centros asistenciales, al tiempo que nos permitirá tener en cuenta las posibles complicaciones, para evitar su aparición y así buscar mejorar la morbilidad por esta causa. Siempre acompañado de un manejo integral que permita abarcar todas las dimensiones afectadas.

Traumatic brain injury is a of the leading causes of death in the world, and many of these are associated with gunshot wounds in the skull. To know management the characteristics and pathophysiology of the lesion will tell as deal with these cases when presented to medical centers, while enabling us to take into account of possible complications, to prevent its occurrence and so try to improve morbidity from this cause. Always accompanied by an integrated management that can encompass all affected dimensions.

Operative treatment of paediatric penetrating head injuries in southern Afghanistan.

The operative management and early post-operative outcome of 16 consecutive cases of paediatric penetrating head injury treated by a single surgeon at a military trauma centre in Southern Afghanistan are retrospectively analysed. The majority of cases of injury were caused by fragments from exploding munitions. The aim of neurosurgical intervention in penetrating head injury is the prevention of wound infection and treatment or prevention of a critical rise in intracranial pressure. In 14 cases in this study, these aims were fulfilled without resort to brain resection, although a delayed cranioplasty procedure was required in 6 patients. Despite the ongoing conflict, families, local communities and coalition forces transport teams combine to make the latter a viable option in Southern Afghanistan, with an excellent short-term outcome.

Gun orientation in self-inflicted craniomaxillofacial gunshot wounds: risk factors associated with fatality.

The purpose of this study was to evaluate whether orientation of a firearm predicts survival, and to identify risk factors associated with fatality in subjects with self-inflicted craniomaxillofacial gunshot wounds. A retrospective cohort study design was used. The primary predictor variable was orientation of the weapon, defined as in the coronal (lateral) or sagittal (anterior-posterior) trajectory pattern. The primary outcome variable was death for subjects on arrival or during their hospital stay. Other covariates measured include demographic, firearm-related, and psychosocial variables. Risk factors for fatality were identified using multivariate logistic regression. Of the 92 subjects that met study inclusion criteria, 47 (67.2) held the firearm in the coronal position. In the full multivariate model, coronal gun orientation (OR=7.7, 95% CI: 2.0, 30.1, p=0.003) and the absence of a psychiatric diagnosis were associated with an increased risk of fatality (OR=0.1, 95% CI: 0.04, 0.5, p=0.002). Coronal firearm orientation was associated with an increased risk of fatality following self-inflicted craniomaxillofacial gunshot injuries. A patient with a documented psychiatric disorder was not found to be more likely to succumb to this type of injury.

Head injury depth as an indicator of causes and mechanisms.

OBJECTIVE: The goal was to measure differences in the causes, mechanisms, acute clinical presentations, injuries, and outcomes of children <36 months of age with varying "greatest depths" of acute cranial injury. METHODS: Children <36 months of age who were hospitalized with acute head trauma were recruited at multiple sites. Clinical and imaging data were collected, and caregivers underwent scripted interviews. Neurodevelopmental evaluations were completed 6 months after injury. Head trauma causes were categorized independently, and subject groups with varying greatest depths of injury were compared. RESULTS: Fifty-four subjects were enrolled at 9 sites. Twenty-seven subjects underwent follow-up neurodevelopmental assessments 6 months after injury. Greatest depth of visible injury was categorized as scalp, skull, or epidural for 20 subjects, subarachnoid or subdural for 13, cortical for 10, and subcortical for 11. Compared with subjects with more-superficial injuries, subjects with subcortical injuries more frequently had been abused (odds ratio [OR]: 35.6; P < .001), more frequently demonstrated inertial injuries (P < .001), more frequently manifested acute respiratory (OR: 43.9; P < .001) and/or circulatory (OR: 60.0; P < .001) compromise, acute encephalopathy (OR: 28.5; P = .003), prolonged impairments of consciousness (OR: 8.4; P = .002), interhemispheric subdural hemorrhage (OR: 10.1; P = .019), and bilateral brain hypoxia, ischemia, or swelling (OR: 241.6; P < .001), and had lower Mental Developmental Index (P = .006) and Gross Motor Quotient (P < .001) scores 6 months after injury. CONCLUSION: For children <3 years of age, head injury depth is a useful indicator of injury causes and mechanisms.

Influence of different types of guns, projectiles, and propellants on patterns of injury to the viscerocranium.

PURPOSE: Gunshot injuries to the oral and craniomaxillofacial region vary with the type of gun used. Computed tomography (CT) is the standard diagnostic tool for assessing tissue damage in patients with gunshot injuries. Cone-beam computed tomography (CBCT) is a new imaging technique that has recently become available for clinical diagnosis. The objective of this study was to characterize injury patterns with a focus on gun types and identify the imaging modality that is best suited to assessing injuries caused by different gun types. PATIENTS AND METHODS: We present the cases of 14 patients who sustained gunshot injuries to the viscerocranium during the past 10 years. The injuries were caused by 8 basic combinations of handguns or long guns with soft lead core projectiles, partial or full metal-jacketed bullets, and different propellants. Diagnosis was based on clinical and radiological findings (including CT and CBCT). RESULTS: We found a direct correlation between the gun/projectile combination on the one hand and the diameter of the wound track, tissue contamination, and tissue destruction on the other. Entrance and exit wounds are indicative of certain gun/projectile combinations. High-density projectiles cause severe artifacts in CT, unlike CBCT, making it difficult to evaluate anatomic structures in close proximity to the projectile. CONCLUSIONS: Every gun/projectile combination is associated with a typical pattern of injury. Even in the absence of the offending projectile, it is thus possible to narrow down the likely gun and/or projectile. In the diagnostic imaging of injuries caused by high-density projectiles, CBCT is more suitable than CT.

[Penetrating gunshot injuries to the head and brain. Diagnosis, management and prognosis]. / Penetrierende Schädel-Hirn-Verletzungen durch Schusswaffen. Diagnostik, Behandlungsmanagement und Prognose.

Gunshot injuries to the head and brain are rare in Germany and the rest of western Europe. With the relatively low number of these injuries here, there are no standard methods of diagnosis and management, and there is some controversy over both. Quite a high proportion of such injuries result from suicide attempts and accidents. The main diagnostic procedure available is computed tomography of the head with contrast medium; in certain cases MRI is indicated. The operative management depends on the extent and prognosis of the injury; a ventricular drain is probably indicated in most cases. Debridement of the bullet's path and removal of the projectile are more controversial. Mortality is extremely high after such injuries; if the victim does survive the prognosis is comparable to that following closed cranial injuries.

Patterns of transorbital intracranial injury: a review and comparison of occult and non-occult cases.

The authors present an illustrative case of occult transorbital penetrating intracranial injury in a child, and review the literature concerning patterns of low-velocity, non-projectile injury during the era of modern CT and MRI study. Review of the mechanism of injury and analysis of surface entry site of penetration in 38 cases suggests recurring patterns of injury in occult and non-occult cases. A classification system based on surface entry zone site is applied to these injuries. Knowledge of the classification system should increase clinical suspicion for this type of often occult, penetrating orbito-cranial injury and direct appropriate investigation to provide earlier detection and diagnosis of the transorbital, intracranial penetration.

Penetrating trauma to the head.

Penetrating trauma to the brain is not as common as blunt trauma; however, the incidence is becoming a frequent occurrence in our society. Rapid transport to trauma centers where definitive care can be rendered is essential. Outcome depends on the site of the missile tract, the presenting neurologic status, and the extent of neurologic tissue destruction. Neurologic deterioration occurs rapidly, and outcome results seem to depend on the patient's neurologic status at the time of surgery. CT scanning is the diagnostic procedure of choice and should be performed if the patient's condition is stable (see Fig. 3). Aggressive removal of missile and bone fragments needs to be balanced by the knowledge that it is preferable to leave behind a few hard-to-reach fragments than to increase the patient's neurologic deficit. CT scanning in the postoperative period is very helpful in identifying abscess formation as well as new or recurrent hematomas, edema, and areas of tissue injury not evident at the time of initial scanning. Antibiotic therapy should be initiated preoperatively. Control of elevated ICP plays a significant role in decreasing mortality and morbidity. Judicious debridement of injured brain combined with medical management of increased ICP will maximize the quality of recovery and increase survivability. Although great strides have been made in reducing mortality and morbidity for trauma patients, the sad issue is that the majority of traumas are preventable. Until society is willing to understand that it needs to make firearm safety a priority, there will always be patients to care for who have sustained a penetrating injury.
