Stab wounds

BACKGROUND: Anecdotal evidence strongly suggests there has been a rise in violent crimes. This study sought to examine trends in injury characteristics of homicide victims in Maryland. We hypothesized that there would be an increase in the severity of wound characteristics. STUDY DESIGN: The Office of the Chief Medical Examiner is a statewide agency designated by law to investigate all homicides, suicides, or unusual/suspicious circumstances. Using individual autopsy reports, we collected data among all homicides from 2005-2017, categorizing them into three time-periods: 2005-2008 (early), 2009-2013, and 2014-2017 (late)...

BACKGROUND: We aimed to reveal the protective effect of body mass index (BMI) and subcutaneous adipose tissue thickness (SATT), together with scores covering the abdomen, in patients with penetrating abdominal trauma. METHODS: The data of 234 abdominal penetrating trauma patients over the age of 16 who applied to the emergency general sur-gery unit of Istanbul Medipol Hospital between 2017 and 2021 were analyzed retrospectively. Sex, age, types of penetrating injuries, BMI, need for blood transfusion and intensive care unit (ICU), mortality, Injury Severity Score (ISS), Penetrating Abdominal Trauma Index (PATI), and Flint Colon Injury Score (FCIS) were recorded...

BACKGROUND: Vascular trauma injuries are associated significantly with disabilities and mortality where prompt diagnosis and management are of great importance. OBJECTIVES: In this study, the authors aim to evaluate the pattern of vascular trauma injuries. METHODS: This descriptive retrospective study was performed on patients with vascular injuries due to trauma referred to (Shohada Ashayer Hospital and Shahid Chamran Hospital, Khorramabad)...

The majority of sharp-force fatalities with stab and/or incised wounds are homicides. However, suicidal sharp-force fatalities with stab and/or incised wounds are also reported. Thus, distinguishing suicidal stab and/or incised wounds from homicidal stab and/or incised wounds is significant from the forensic perspective. This scoping review primarily summarizes the existing research findings on the differentiation of suicide from homicide in sharp-force fatalities with stab and/or incised wounds. The literature was systematically searched on February 28, 2023, using the PubMed database...

Stab wound analysis is a relatively new field of study in forensic science, and there is currently much debate regarding the effectiveness of the analysis due to a lack of validation studies. Furthermore, the underlying viewpoints on the success of stab wound analysis vary. Examination of cut marks, for example, can reveal a variety of characteristics which can be used to determine the type of weapon that was used to inflict them. However, published studies are not consistent when identifying knife blade characteristics, instead considering a wide variety of morphological aspects and their potential value in forensic scenarios...

INTRODUCTION: This study sought to evaluate injury frequency of penetrative trauma before and after stay-at-home orders were implemented due to COVID-19 in Wisconsin. METHODS: Patients who presented to a level I trauma center from January 2018 through December 2021 with a mechanism of injury of firearm or stab wound were included. The study was split into pre-COVID (January 2018-February 2020) and COVID (March 2020-December 2021) periods. Statistical analysis included chi-square tests and interrupted time series analysis...

INTRODUCTION: Anterior abdominal stab wounds (AASW) are a heterogeneous presentation with evolving management over time and heterogenous practice between centres. The aim of this scoping review was to identify, characterise and classify paradigms for trauma laparoscopies for AASW. METHODOLOGY: Studies were screened from Embase, Medline, Scopus, Cochrane Library and Web of Science from 1 January 1947 until 1 January 2023. Extracted data included indications for trauma laparoscopies vs laparotomies, and criteria for conversion to an open procedure...

Isolated injury to the deep motor branch of the ulnar nerve caused by stabbing is sporadic, with only one reported case in the English-language literature. We report one such case treated successfully using nerve grafting. A 33-year-old patient had sustained a stab wound to the right hypothenar eminence and showed a claw hand deformity. Needle electromyography study revealed denervation potentials with no voluntary motor unit action potentials (MUAPs) in the first dorsal interosseous (FDI) muscles. Nerve exploration revealed a neuroma-in-continuity in the intrinsic motor branch of the ulnar nerve...

Penetrating trauma is usually divided into stab and gunshot wounds (GSW). When considering GSW, the initial assessment involves the identification of all the wounds, to understand the projectile's trajectory as well as to determine which anatomic structures might have been damaged [1]. Rarely, the projectile might not leave the victim's body and embolize to a different region through large blood vessels. Known as Missile Embolism (ME), this uncommon complication can compromise multiple body segments, resulting in severe injuries, whether it occurs through an artery or a vein, such as pulmonary embolism, cardiac-valve incompetence, limb-threatening ischemia, coronary infarct, and stroke [2,3]...

INTRODUCTION: Forensic pathologists are frequently confronted with questions about whether an injury is likely to have been inflicted by an assault or be self-inflicted. However, little is known of the epidemiological variables that might be applicable to differentiate between homicides and suicides in deaths caused by single stab injuries to the trunk. METHOD: Using the Swedish forensic autopsy register, we identified 94 homicides and 45 suicides between 2010 and 2021 in which death followed a single stab injury to the trunk...

Seminars in Thrombosis and Hemostasis (STH) celebrates 50 years of publishing in 2024. To celebrate this landmark event, STH is republishing some archival material. This manuscript represents the second most highly cited paper ever published in STH. The manuscript published without an abstract, and essentially represented a State of the Art Review on the bleeding time, a relatively invasive procedure that required an incision on the skin or earlobe of a patient, and timing how long it took for the incision to stop bleeding...

This study examines the pattern of rib injuries occurring in cases of fatal torso stab wounds in Ireland between 2011 and 2018. It has been suggested by previous studies that rib fractures are not commonly sustained in stab wounds to the torso. We wanted to ascertain whether this was the case, as our data suggested that rib fractures were frequent, and where a rib is fractured there is a higher chance of organ injury and death, making this an important area of study. One hundred and forty seven cases of fatal stab wounds from an eight-year period were retrospectively reviewed...

BACKGROUND: Various instruments, including glass fragments, can inflict sharp-force damage, resulting in injuries ranging from superficial wounds to life-threatening trauma. This case report explores the lethal consequences of a 78-year-old man accidentally sustaining a stabbed-incised wound after falling against an ordinary glass door, leading to fatal bleeding from the subclavian artery. CASE REPORT: The man's fall caused a sharp-edged glass fragment to penetrate his neck, resulting in a fatal outcome despite resuscitation attempts...

BACKGROUND: Penetrating trauma to the head and neck (HN) has increased during the past decade in Sweden. This aim of this study was to characterize these injuries and to evaluate the outcome in patients treated at a tertiary trauma centre. METHODS: Swedish trauma registry (SweTrau) data was extracted on patients with HN injuries admitted to Karolinska University Hospital, Stockholm, between 2011 and 2019. Outcome information was extracted from hospital records, with primary endpoints focusing of physiological outcome measures and secondary endpoints on surgical and radiological outcomes...

OBJECTIVE: To evaluate the diagnostic value of metagenomic next-generation sequencing (mNGS) in Vibrio vulnificus ( V. vulnificus ) infection. METHODS: A retrospective analysis of patients with V. vulnificus infection at the Fifth Affiliated Hospital of Sun Yat-Sen University from January 1, 2020 to April 23, 2023 was conducted. 14 enrolled patients were diagnosed by culture or mNGS. The corresponding medical records were reviewed, and the clinical data analyzed included demographics, epidemiology laboratory findings, physical examination, symptoms at presentation, antibiotic and surgical treatment, and outcome...

Accurate representation of findings in autopsy photographs is of paramount importance. This study investigates the influence of photography training on the precision of autopsy photographs in depicting these findings. In cases of fatal gunshot and stab wounds, photographs were concurrently taken by individuals without photography training (Group A) and a trained medical photographer (Group B). Two sets of photos were then anonymously presented to forensic medicine specialists, who had no prior knowledge of the associated autopsies, along with relevant survey questions...

INTRODUCTION AND IMPORTANCE: Penetrating cardiac injury is rare and historically known to have very poor prognosis. Even today, 90 % of patients die before arriving to hospital. Even though patient presentations can be atypical, organized timely intervention can lead to survival. CASE REPORT: A 21 years old arrived 5 h after stab injury to right anterior chest. He was hypotensive with a sucking wound bleeding on his right chest as well as hemothorax on the same side...

• Penetrating chest injuries vary in presentation and are associated with mortality. • Pericardial compliance and rate of bleeding cause hemodynamic lability. • Objective judgment of the mechanism of injury is needed to anticipate exact injuries. • Cardiac ultrasound with advanced 3D imaging is an increasingly accessible tool. • Defining the damage to the normal anatomy guides further definitive management.

BACKGROUND: While recurrent penetrating trauma has been associated with long-term mortality and disability, national data on factors associated with reinjury remain limited. We examined temporal trends, patient characteristics, and resource utilization associated with repeat firearm-related or stab injuries across the US. METHODS: This was a retrospective study using 2010-2019 Nationwide Readmissions Database (NRD). NRD was queried to identify all hospitalizations for penetrating trauma...
