BACKGROUND: Penetrating neck trauma (PNT) due to gunshot injuries is one of the challenging conditions with the potential for both significant morbidities and mortality.
OBJECTIVE: There are significant concerns in the approach to patients with spinal gunshot injuries. Surgery indications, methods of surgery, and management of CSF leaks are the main concerns of these patients.
METHODS: An 11-year-old boy was referred to our center with a single gunshot wound to the left side of the posterior cervical region 2 days ago with cerebrospinal fluid leakage and left arm weakness.
RESULTS: The patient underwent surgery, and the pellet was removed. His left arm weakness fully recovered after the operation, and no new symptoms developed during the 1-year follow-up.
CONCLUSIONS: Timely surgery could dramatically improve outcomes in PNT patients with mild symptoms and prevent worsening neurological defects.

Several studies have been performed to recognize the main features in homicide and suicide sharp wound-related death, revealing that a single cutting wound to the neck is an infrequent event in suicide cases, and several hesitation marks near the fatal injury are usually present. We report a case of an atypical self-inflicted cutthroat injury without tentative marks involving a 79-year-old female. The weapon used, a kitchen knife, was found at the crime scene. The wound had clean margins, and no other incisions were found. Scene circumstances, namely the absence of signs of a break-in, the victim found on the bed, the knife located near the body, the vital wound in an accessible site, and the absence of defense injuries, collectively support a likely suicide. A literature review was also performed to compare forensic data of the case presented with the other 6 cases reported regarding atypical suicide characterized by a single incising cut to the throat without hesitation marks. Given the few cases reported and the lack of gross descriptions and histopathological data available in the literature, additional knowledge of such a case may help forensic pathologists in the identification of suicidal events when a single neck injury is observed. In this frame, suicide by a unique single incising cut to the throat without hesitation marks near the lethal injury may be observed as an atypical presentation, and the crime scene investigation, together with additional background information of the deceased, aid in the identification of the manner of the death.

Penetrating neck trauma is becoming a more frequently encountered presentation in UK emergency departments. Although largely attributable to violent crime, other aetiologies are on the rise. This study aimed to review changes in the pattern of penetrating neck injury (PNI) over a five-year period at our level 1 major trauma centre. Data were retrospectively collected on all patients presenting to the emergency department with PNIs between 2016 and 2021. The number of these injuries doubled between 2016 and 2021, accounting for 11% of all penetrating trauma in 2021. The majority of patients were male (87%). Violence remained the predominant aetiology but numbers of self-harm-related PNIs trebled between 2018 and 2021. PNIs are on the rise. These injuries remain complex to manage and require a multidisciplinary approach. Tackling violent crime remains essential in combating PNIs, but focus must also be placed on identifying and supporting individuals most at risk of deliberate self-harm from a deterioration in mental health.

The pattern of neck injuries sustained in fatal cases of external compression to the neck is recorded during Post Mortem Examinations (PME), to assist in the interpretation of the circumstances that led to death. In this study, the PMEs performed for 298 cases of hanging and strangulation occurring between 2016 and 2020 in Ireland were retrospectively reviewed for the purpose of recording and collating the external and internal neck injuries observed during each PME, as well as the toxicology results for each decedent. Statistical analysis was performed to investigate potential novel associations between anthropometric variables pertaining to the decedents and the PME findings in cases of hanging and strangulation, serving to add further data to the existing body of research in this area and to assist in the resolution of future cases of hanging or strangulation where there are conflicting findings. In completing statistical analysis, it was found that there was no discernible association between the occurrences of cartilaginous neck fractures (CNFs) with increasing ligature width. Positive associations between increasing weight and BMI of the decedents were identified, and a significantly positive association between the increasing height of the decedent and the incidence of CNFs were identified. Analysis of the toxicology demonstrated that antipsychotics were implicated most frequently in cases of incomplete and complete hanging associated with CNFs and that opioids were implicated most frequently in cases of manual and ligature strangulation associated with CNFs.
OBJECTIVE: To record the pattern of neck injuries sustained in retrospective cases of hanging and manual/ligature strangulation and to collate these findings so as to provide scientific evidence to support the interpretation of the findings in future cases of suicidal hanging and homicidal manual/ligature strangulation for the purpose of medicolegal investigation. To analyse the associations between the occurrence of neck fractures and anthropometric variables pertaining to the victims in cases of complete hanging.
METHODS: The reports of 298 Post Mortem Examinations (PMEs) performed for cases of hanging and manual/homicidal ligature strangulation between 2016 and 2020 in Ireland were retrospectively reviewed. Pseudoanonymised data sets were recorded for each report, which included the following parameters: neck injuries (soft tissue and cartilaginous), weight, height, BMI and ligature width, toxicology, noose position, ligature material, tongue protrusion, sex and age. Permission for the use of this data was sought from the pathologists and coroners involved in these cases. The data was analysed according to descriptive statistical methods and logistic regression analysis.
RESULTS: Logistic regression analysis was undertaken to examine the associations between unit increases in ligature width and increases in a set of physical characteristics of the decedents (weight, BMI and height) with the occurrence of CNFs. Increasing ligature width was not found to increase the likelihood of a CNF occurring, where the Odds Ratio (OR) for this event occurring was 0.9596. Unit increases in body weight and BMI were found to increase the likelihood of the occurrence of a CNF with ORs of 1.0166 and 1.0607 respectively. Increasing height of the decedent yielded an OR = 4.64, demonstrating that CNFs are significantly more likely to occur with increasing height (CI 95 %: 0.2915, 73.9559).
CONCLUSIONS: According to the statistical analysis performed for this study, increasing weight, height and BMI are parameters of the decedents which increase the likelihood of the occurrence of CNFs in cases of complete hanging.

UNASSIGNED: Suicide by firearm is a significant public health concern in specific regions of the world. Depending on firearm availability, any type of firearm may be used, including handguns, shotguns, and long rifles. Common entrance wound sites in suicidal gunshot wounds include the head, with classic gunshot wound locations including the temple, the forehead, the submental aspect of the chin, and inside the mouth. Occasionally, suicidal gunshot wounds occur in atypical body locations such as the back of the head and neck. Given their relative rarity, suicidal gunshot wounds in these regions may be mistaken for homicides. In this report, we present 5 cases of suicidal gunshot wounds to the back of the head and/or neck. In our series, we focus on differentiating each case from homicides involving gunshot wounds in similar areas of the head and neck.

BACKGROUND: Intraosseous hemangioma is a rare benign vascular tumor of the bone that can affect any body part; however, the most common site is the vertebra, followed by calvarial bones.
METHODS: We present a case of intraosseous hemangioma in a 23-year-old male who presented a feeling of fullness in the throat for 3 months. The hyoid bone level had a hard mass of about 5 cm. Fine needle aspiration showed 5 mL dark bloody aspirates. Magnetic resonance image showed a 5.3 cm mixed signal intensity lesion in the hyoid body.
METHODS: Histopathologic examination showed intraosseous hemangioma with aneurysmal bone cyst (ABC)-like changes in the hyoid bone.
METHODS: The mass was completely removed without significant problems.
RESULTS: Complete mass excision and symptomatic improvements were achieved, and no subsequent relapses were observed.
CONCLUSIONS: The authors experienced a case of intraosseous hemangioma with ABC-like changes. There has been no case report of intraosseous hemangioma in the hyoid bone. This case showed a spectral pattern of the ABC-like changes developing from the underlying bone tumor as a secondary change. ABC-like changes in bone tumors can mislead the diagnosis. Careful examination of the tumor is essential for the correct diagnosis of ABC or ABC-like changes.

Vehicle-assisted ligature strangulation is an extremely rare suicide method. We report a case of a 43-year-old man who secured one end of a nylon rope to a tree and the other end around his neck, then got inside his vehicle and stepped on the gas, leading to an incomplete decapitation. A sharply demarcated encircling ligature mark was found upon external examination, along with a deep laceration in the anterior region of the neck. The severance plane passed between the third and fourth cervical vertebrae, with diffuse haemorrhagic infiltration of the cervical muscles, in accordance with autopsy findings reported in the literature. The lung histological examination described a large amount of red blood cells and pulmonary oedema. A review of the literature concerning suicidal vehicle-assisted ligature strangulation cases allowed us to investigate some common autopsy findings, as well as the rope features relevant to the beheading.

BACKGROUND: Sclerosing epithelioid fibrosarcoma is an aggressive sarcoma subtype with poor prognosis and limited response to conventional chemotherapy regimens. Diagnosis can be difficult owing to its variable presentation, and cases of sclerosing epithelioid fibrosarcoma are rare. Sclerosing epithelioid fibrosarcoma typically affects middle-aged individuals, with studies inconsistently citing gender predominance. Sclerosing epithelioid fibrosarcoma typically arises from the bones and soft tissues and often has local recurrence after resection and late metastases. Immunohistochemical staining typically is positive for mucin-4. Werner syndrome is due to an autosomal recessive mutation in the WRN gene and predisposes patients to malignancy.
METHODS: A 37-year-old Caucasian female presented to the emergency department with 4 months of dyspnea and back pain. She had been treated for pneumonia but had persistent symptoms. A chest, abdomen, and pelvis computed tomography showed near-complete right upper lobe collapse and consolidation, mediastinal lymphadenopathy, lytic spinal lesions, and a single 15-mm hypodense liver nodule. The patient underwent a transthoracic right upper lobe biopsy, bronchoscopy, endobronchial ultrasound with transbronchial lymph node sampling, and bronchoalveolar lavage of the right upper lobe. The bronchoalveolar lavage cytology was positive for malignant cells compatible with poorly differentiated non-small cell carcinoma; however, the cell block materials were insufficient to run immunostains for further investigation of the bronchoalveolar lavage results. Consequently, the patient also underwent a liver biopsy of the liver nodule, which later confirmed a diagnosis of sclerosing epithelioid fibrosarcoma. Next-generation sequencing revealed a variant of unknown significance in the WRN gene. She was subsequently started on doxorubicin.
CONCLUSIONS: Sclerosing epithelioid fibrosarcoma is a very rare entity, only cited approximately 100 times in literature to date. Physicians should be aware of this disease entity and consider it in their differential diagnosis. Though pulmonary involvement has been described in the context of sclerosing epithelioid fibrosarcoma, this malignancy may affect many organ systems, warranting extensive investigation. Through our diagnostic workup, we suggest a possible link between sclerosing epithelioid fibrosarcoma and the WRN gene. Further study is needed to advance our understanding of sclerosing epithelioid fibrosarcoma and its clinical associations as it is an exceedingly rare diagnosis.

BACKGROUND: Traumatic hip dislocation with ipsilateral femoral neck fracture, intertrochanteric fracture and acetabular fracture is a rare and serious injury that occurs mostly in young patients and after high-energy trauma. The treatment of these injuries is a major challenge for orthopedic surgeons; it can have devastating consequences if not treated properly, including avascular necrosis of the femoral head and traumatic osteoarthritis of the hip. In previous case reports only internal fixation of femoral neck fracture was performed without revascularisation and there was a lack of long-term follow-up results. In this report, we fixed the fracture revascularised the patient, and obtained good prognostic results at up to 20 months of follow-up.
METHODS: Here, we report an 18-year-old patient with systemic polytrauma resulting from a car accident. The trauma included ipsilateral posterior hip dislocation, acetabular fracture, femoral intertrochanteric fracture, and femoral neck fracture. In addition, the patient also had an ipsilateral open tibiofibula fracture. We chose the surgical treatment of a proximal femoral locking compression plate (PFLCP), femoral quadratus bone flap graft, and cannulated compression screw to treat the proximal femoral fracture. The patient was followed up for nearly 20 months; the range of motion of his hip was close to normal, and his hip function was good.
CONCLUSIONS: Traumatic hip dislocation with ipsilateral femoral neck fracture, intertrochanteric fracture and acetabular fracture is a rare and serious injury, and surgical intervention is often needed. Because of the high risk of femoral head necrosis in such complex injuries, it is very important to protect/restore the blood supply of the femoral head during surgery. Therefore, in younger patients, we believe that the use of a quadratus femoris bone flap graft and PFLCP is an acceptable treatment for this severe injury. We discuss the management of this rare case and review the current literature to provide the best evidence-based recommendations for this injury pattern. We conclude that for patients with complex ipsilateral proximal femoral and acetabular fractures combined with hip dislocation, the key to surgical treatment, in addition to anatomic reduction and good fixation, is the primary reconstruction of the femoral head blood supply.

Fractures of the laryngohyoid complex are classically associated with deaths due to strangulation. Recent studies, however, indicate the possible presence of such fractures in fatal falls. The primary focus of this systematic review is to analyze the characteristics of laryngohyoid fractures in the context of falls to aid in a more accurate interpretation of autopsy findings. Search for relevant literature occurred on PubMed on the 26th of October 2022, and Embase and Web of Science on the 5th of November 2022. Inclusion criteria included being a primary study, published in English, involving fatal falls and injuries to the laryngohyoid complex, and presenting sufficient details about the relevant cases. Four case reports and six descriptive retrospective studies were included in the final analysis yielding a sum of 38 cases. The risk of bias was assessed using the Joanna Briggs Institute (JBI) critical appraisal tools. Potential limitations of this study include the inclusion of case reports and studies published in English only. The cumulative male-to-female ratio was 23:15 with a mean age of 48 years old. The fall height ranged from standing height to 60 m. Forty-three fractures to the laryngohyoid complex were identified with the thyroid cartilage most commonly affected, followed by fracture of the hyoid bone, and finally the cricoid cartilage. While cases of falls did indeed display hallmark laryngohyoid findings classically displayed in strangulation, they also featured unique presentations such as fractures of the clavicle and a reduced prevalence of conjunctival petechiae.
