The authors present a case of a complex suicide of a 60-year-old woman found dead on her bed. A blank pistol Umarex caliber 9-mm, several blank cartridges and a lot of drug packages were discovered near the body. The woman suffered from a psychiatric depression. There were three gunshot wounds on the body: in the right temporal region, on the palatum of the mouth and on the left chest wall. The gunshot wounds in the right temporal region and in the mouth had central circle defects with the margins of stellate or star-like appearance and blackening...

BACKGROUND: Traumatic rib fractures can cause chest complications that need further treatment and hospitalization. We hypothesized that an increase in the number of displaced rib fractures will be accompanied by an increase in chest complications. METHODS: We retrospectively reviewed the trauma registry between January 2013 and May 2015 in a teaching hospital in northeastern Taiwan. Patients admitted with chest trauma and rib fractures without concomitant severe brain, splenic, pelvic or liver injuries were included...

PURPOSE: The aim of this study was to assess the performances of unenhanced post-mortem computed tomography (CT) to detect thoracic injuries in violent death. MATERIALS AND METHODS: Retrospectively, we conducted a review of unenhanced CT scans of 67 victims of violent deaths with thoracic injuries and compared CT findings with the results of clinical autopsy. Our gold standard was a comparison of CT scans with autopsy discussed in a monthly forensic radiology multidisciplinary team meeting (MDTM)...

BACKGROUND: After severe trauma, patients develop a norepinephrine-mediated persistent, injury-associated anemia. This anemia is associated with suppression of bone marrow (BM) erythroid colony growth, along with decreased iron levels, and elevated erythropoietin (EPO) levels, which are insufficient to promote effective erythropoiesis. The impact of norepinephrine on iron regulators, such as ferroportin, transferrin, and transferrin receptor-1 (TFR-1), is unknown. Using a clinically relevant rodent model of lung contusion (LC), hemorrhagic shock (HS), and chronic stress (CS), we hypothesize that daily propranolol (BB), a nonselective β blocker, restores BM function and improves iron homeostasis...

OBJECTIVES: We analyzed chest computed tomographic scan to evaluate parenchymal lung injury and its clinical significance in patients who received standard cardiopulmonary resuscitation and were resuscitated from cardiac arrest. METHODS: We enrolled nontraumatic out-of-hospital cardiac arrest patients older than 19 years who had been admitted to the emergency department in cardiac arrest and successfully resuscitated after cardiopulmonary resuscitation. Chest computed tomography was obtained immediately after return of spontaneous circulation (ROSC)...

BACKGROUND: Thoracic injuries are a major cause of death associated with blunt trauma in children. Screening for injury with chest x-ray study, compared with chest computed tomography (CT) scan, has been controversial, weighing the benefits of specificity with the detriment of radiation exposure. OBJECTIVE: To identify predictors of thoracic injury in children presenting as trauma activations to a Level I trauma center after blunt torso trauma, and to compare these predictors with those previously reported in the literature...

BACKGROUND/AIMS: Lung contusion is a potentially lethal injury. Pleckstrin homology-like domain family A, member-1 (PHLDA1) is known to play crucial roles in cell proliferation and apoptosis. In this study, we investigated the biological role of PHLDA1 in lung contusion. METHODS: The expression levels of PHLDA1 and TLR2 were detected by real time PCR and western. The cytokines were determined by ELISA. The inflammatory factors were detected by flow cytometry. The lung injury was determined by HE staining...

OBJECTIVE: To understand the fate and regulation of hypoxic type II alveolar epithelial cells (AECs) after lung contusion (LC). BACKGROUND: LC due to thoracic trauma is a major risk factor for the development of acute respiratory distress syndrome. AECs have recently been implicated as a primary driver of inflammation in LC. The main pathological consequence of LC is hypoxia, and a key mediator of adaptation to hypoxia is hypoxia-inducible factor (HIF)-1. We have recently published that HIF-1α is a major driver of acute inflammation after LC through type II AEC...

BACKGROUND/AIMS: Pneumonia is a significant risk factor for the development of venous thrombosis (VT). Cell-adhesion molecules (CAMs) are linked to the pathogenesis of both pneumonia and VT. We hypothesized that remote infection would confer a prothrombogenic milieu via systemic elevation of CAMs. METHODS: Lung injury was induced in wild-type (C57BL/6) mice by lung contusion or intratracheal inoculation with Klebsiella pneumoniae or saline controls. K. pneumoniae-treated mice and controls additionally underwent inferior vena cava (IVC) ligation to generate VT...

BACKGROUND: Propranolol has been shown previously to restore bone marrow function and improve anemia after lung contusion/hemorrhagic shock. We hypothesized that daily clonidine administration would inhibit central sympathetic outflow and restore bone marrow function in our rodent model of lung contusion/hemorrhagic shock with chronic stress. METHODS: Male Sprague-Dawley rats underwent 6 days of restraint stress after lung contusion/hemorrhagic shock during which the animals received clonidine (75 μg/kg) after the restraint stress...

Motor vehicle accident is the most common cause of blunt cardiac injury (BCI) in children (85.3%) due to the height of the child in relation to proper restraints and the compliant pediatric rib cage (J Trauma. 1996;40:200-202). Trauma to the chest wall may lead to injury of the myocardium, resulting in myocardial contusion, ventricular septal defect (VSD), ventricular free wall rupture, or valve compromise (J Trauma. 1996;40; 200-202; Heart Lung. 2012;41:200-202; J Inj Violence Res. 2012;4:98-100). There are several proposed mechanisms for the formation of VSD after blunt chest trauma including rupture of ischemic myocardium related to the initial trauma and reopening of a spontaneously closed congenital VSD...

OBJECTIVES: This study aimed to assess the short-term respiratory tolerance and haemodynamic efficiency of low-volume resuscitation with hypertonic saline and hydroxyethylstarch (HS/HES) in a pig model of lung contusion and controlled haemorrhagic shock. We hypothesised that a low-volume of HS/HES after haemorrhagic shock did not impact contused lungs in terms of extravascular lung water 3hours after trauma. METHODS: A lung contusion resulting from blunt chest trauma was induced in 28 anaesthetised female pigs with five bolt-shots to the right thoracic cage, followed by haemorrhagic shock and fluid resuscitation...

Tracheobronchial injuries are rare cases requiring skillful airway management. We report a challenging case of tracheobronchial injury in a young adult who was run over by a tractor and was referred to us from a peripheral hospital with endotracheal tube in situ. He was severely hypoxaemic on initial presentation. Diagnostic work up showed high suspicion for right bronchial transection along with left lung upper lobe contusion. Due to deteriorating clinical condition of the patient and despite immediate unavailability of fibreoptic bronchoscope, patient was immediately taken up for right posterolateral thoracotomy and double lumen tube was inserted...

Acute respiratory distress syndrome (ARDS) is a fulminant clinical disorder of varied etiology, characterized by diffuse lung injury and severe hypoxemia. It is a leading cause of ICU admission and the associated high mortality has sparked a lot of research on etiology, outcome, scoring systems, mortality predictors, biomarkers including inflammatory cytokines and even genomics in ARDS. The previously used AECC (American European Consensus Conference) definition (1994) of ARDS was replaced by the recent Berlin definition (2012) so as to improve its validity and reliability...

BACKGROUND: The present objective was to investigate endogen erythropoietin (EPO) level and relationship to oxidative stress within the first 24 hours of blunt chest trauma-induced pulmo-nary contusion (PCn) in a rat model. METHODS: Thirty-five rats were divided into 3 groups. In the baseline control group (BC, n=7), rats were uninjured and untreated. In the positive control group (PC, n=21) rats were injured but untreated. In the EPO-24 group (n=7), rats were injured and a single dose of intra-peritoneal EPO (5000 IU/kg) was administered immediately after lung injury...
