ABSTRACT

OBJECTIVE: This study aimed to investigate specific protein expression of injured intestinal mucosa induced by diclofenac, and explore the protective effects of teprenone on it. METHODS: Intestinal damage of Sprague Dawley male rats was gradually induced by the intragastric administration of diclofenac. After the last drug administration, the intestinal mucosa was taken off with an interval of 24 h, subsequently, its general histological injury and ultrastructure were observed and analysed by a transmission electron microscope. The expression levels of PAR1 and PAR2 protein were detected by immunohistochemistry and real-time polymerase chain reaction (PCR). RESULTS: The Reuter and Chiu scores of small intestinal damage were 5.63 ± 1.30 and 4.25 ± 0.70 respectively in the model group, which could be protected by teprenone (100 mg/kg⋅day) with the degree of 55.7% and 44%. Optical microscopy and transmission electron microscope showed that intestinal mucosa and ultrastructure were severely damaged. Distributed in the cytoplasm or aligned with the nucleus, the expression of PAR1 and PAR2 was significantly upregulated after the administration of diclofenac, while it was relieved after the treatment of teprenone. CONCLUSION: Our study presents a new view that teprenone might protect NSAIDs-induced (diclofenac) intestinal injury via suppressing the expression of PAR1 and PAR2.

ABSTRACT

Crossbow fatalities are a rare occurrence, but crossbow use is on the rise. The manner of death in crossbow fatalities is overwhelmingly opined accident or suicide, not homicide. Despite their increasing use and reports of at least 14 crossbow-related homicides in the media for the last 5 years, crossbow homicides are rarely reported in the medical literature; only 10 articles that discussed 20 crossbow homicides were identified in the PubMed database. Here, we describe a case of a 20-year-old man who was found dead in his driveway after being shot in the abdomen with a crossbow by another person. The crossbow bolt had a mechanical 2-blade broadhead that transected the descending aorta and lodged in his vertebra. When completing a medicolegal death investigation and postmortem examination on suspected crossbow-related deaths, knowledge of crossbow components, its utility as a weapon, wound patterns, and how it can cause death are important. This case serves to build on the limited medical literature of crossbow homicides, educate forensic pathologists about the features of crossbow deaths, and highlight manner of death considerations.

ABSTRACT

Investigation of a complex suicide is a challenging task, particularly when the combination of modalities adopted is rare and unplanned. There is often a significant likelihood of labeling the case as a homicide. We present an interesting case of unplanned complex suicide with self-stabbing and head injury resulting from intentionally being struck by a train. There were also hesitation cuts evident over the neck and left wrist. This case highlights the importance of studying the nature and characterization of the wounds, examination of clothes, and examination of the scene to safely conclude the cause and the manner of death.

ABSTRACT

The use of postmortem computed tomography (CT) has been described in many articles concerning gunshot injuries. Postmortem magnetic resonance imaging (MRI) for better assessment of soft tissue injuries has also been mentioned in the literature, albeit much less often. The use of postmortem MRI for abdominal gunshot wounds has not been previously presented in the literature. The present case report describes the findings of an abdominal gunshot wound detected by postmortem CT and MRI, followed by an autopsy. The main imaging findings on CT were a hyperdense ring at the entrance wound, which indicated the muzzle imprint mark, a hyperdense region beneath the skin, which was suggestive of combustion residue, gas cavities surrounding the bullet path, which might be related to the temporary cavity, and a fracture of the 13th rib on the left. Magnetic resonance imaging provided a clear depiction of defects in the muscle tissue and peritoneal fat, as well as an injury to the left kidney and a large volume of blood in the abdominal cavity. Computed tomography combined with MRI provided a descriptive presentation of the intracorporeal trajectory noninvasively. Autopsy confirmed the radiologic findings but additionally revealed further relevant findings, which were not detected radiologically, such as a duodenal perforation. Autopsy also detected subendocardial hemorrhages and shock kidney, which were consistent with severe blood loss.The imaging findings and their interpretations are discussed in this case report, as well as the role of CT and MRI in the assessment of abdominal gunshot wounds compared with autopsy.

ABSTRACT

Impalement injuries occur when a large foreign body traverses or penetrates a body cavity or extremity. Nowadays, impalement injuries are uncommon and are usually a consequence of a fall onto a blunt object or a road accident. The authors report a case of a woman found dead in her apartment, seemingly killed by a firearm injury to the abdomen. However, after the autopsy was carried out, it became clear that the injuries had the features of an impalement. After the inquiry, the murder weapon was identified as a battering ram, used by the robbers to break into the house of the woman. This is the first case ever described in literature where a battering ram has been used to impale someone. This case emphasizes the importance of an accurate description of injuries, also with photographs, in order to achieve effective recognition of the wound patterns as they may correspond to specific and unusual weapons.

ABSTRACT

Pig bite injuries are an infrequently described consequence of human-animal conflict. The domestic pig is thought to be a placid animal not given to unprovoked aggression. We report 2 separate cases of children managed at our institution who sustained abdominal injuries after attack by domestic pigs in rural Zimbabwe. Both incidents occurred at home in remote rural areas with long prehospital transport times. Initial resuscitative interventions were performed in both cases in the prehospital setting and at poorly resourced peripheral hospitals before referral. Prophylactic antibiotics were also given in both cases. Laparotomy was performed for both patients. Reduction of eviscerated bowel, exploratory laparotomy, and peritoneal lavage were performed with closure of the abdominal wounds. No surgical site infections were encountered, and patients were subsequently discharged after an uneventful convalescence. Prehospital care is the crucial phase of management of these injuries, which frequently take place in remote, rural settings and usually have a long time to definitive intervention. Expeditious laparotomy and exploration are indicated, as well as meticulous attention to techniques to avert infectious complications. Despite the generally placid temperament of the domestic pig, their bite can result in grave injuries, including abdominal evisceration necessitating prompt referral and emergency laparotomy.

ABSTRACT

OBJECTIVE: The management of renal trauma has been changing in recent years so that nowadays, even in high grades, an initial conservative treatment is advocated. The aim of this work is to review the presentation, initial attitude and evolution of the renal traumas treated in our institution. MATERIAL AND METHODS: Retrospective review of patients with renal trauma treated at our institution in the last 10 years. Epidemiological variables, production mechanism, pediatric trauma index (PTI), treatment and evolution were analyzed. RESULTS: We studied 26 patients, 18 men (69.3%). The most frequent mechanism was the direct hit in 11 patients (42.31%). The most frequently side affected was the right one in 14 patients (53.85%). The grade III traumatism according to American Association for the surgery of Trauma (AAST) was the most repeated, 11 patients (42.31%). Nine patients (44.55%) presented concomitant injuries in other solid organs. In 24 patients (92.30%) the initial treatment was conservative with supportive measures. One patient presented with hemodynamic instability and an urgent intervention was conducted, performing a supraselective embolization with immediate control of the active bleeding. In another patient, a double J catheter was placed due to disruption of the excretory tract. Of the patients treated conservatively initially, only one patient (4.1%) required secondary surgical maneuvers due to a complication. CONCLUSIONS: In patients with renal trauma, non-surgical treatment is safe and effective. In case of hemodynamic instability or complication, interventional radiological techniques have been demonstrated to be safe and effective in the pediatric population.


OBJETIVO: El manejo del traumatismo renal ha ido variando en los últimos años de modo que en la actualidad, incluso en los grados altos, se aboga por un tratamiento inicial conservador. El objetivo de este trabajo es revisar la presentación, actitud inicial y evolución de los traumatismos renales atendidos en nuestra institución. MATERIAL Y METODOS: Revisión retrospectiva de pacientes con traumatismo renal atendidos en los últimos 10 años. Se analizaron las variables epidemiológicas, mecanismo de producción, índice de trauma pediátrico (ITP), tratamiento y evolución. RESULTADOS: Se estudiaron 26 pacientes, 18 varones (69,23%). La causa más frecuente fue el golpe directo en 11 pacientes (42,31%). El lado más frecuentemente afectado fue el derecho en 14 pacientes (53,85%). El traumatismo grado III según la American Association for the Surgery of Trauma (AAST) fue el más común, 11 pacientes (42,31%). Nueve pacientes (44,55%) presentaron lesiones concomitantes en otros órganos sólidos. En 24 pacientes (92,30%) el tratamiento inicial fue conservador con medidas de soporte. Un paciente se presentó con inestabilidad hemodinámica y se intervino de forma urgente realizándose embolización supraselectiva con control inmediato del sangrado activo. En otro paciente se colocó un catéter doble J por disrupción de la vía excretora. De los pacientes tratados de manera conservadora inicialmente solo 1 paciente (4,1%) requirió maniobras quirúrgicas secundarias debido a una complicación. CONCLUSIONES: En pacientes con traumatismo renal el tratamiento no quirúrgico es seguro y eficaz. En caso de inestabilidad hemodinámica o complicación, las técnicas radiológicas intervencionistas han demostrado ser seguras y efectivas en la edad pediátrica.

ABSTRACT

Determining the manner of death in cases involving multiple stab injuries from a knife is generally straightforward. The medico-legal investigation of a stabbing death caused by a single stab injury from a knife comprises a smaller but potentially more problematic subset of forensic cases. We reviewed our institute's experience with single stab injuries and endeavored to identify features identified at the post-mortem examination which may aid in the differentiation between cases of homicide, suicide and accidental death. The single stab injury was to the left chest in the majority of deaths from homicide and from suicide. Clothing was nearly always involved in cases of homicide, but was also seen in cases of suicide. The knife was found in situ in 9 of the 11 cases of suicide involving a chest injury, but was not seen in any of the cases of homicide. There were no cases of an accidental single stab death from a knife in our records. Clinical data on accidental stab injuries was sought via a search of the medical records of a major tertiary referral hospital. A single non-fatal case of an accidental single stab injury from a knife was identified after the conclusion of our study period. Accidental stab injuries from a knife causing injury or death are rare.

ABSTRACT

AIM: To determine the frequency of cardiopulmonary resuscitation (CPR)-related injuries and factors involved in their occurrence, data based on forensic autopsy and postmortem computed tomography (PMCT) during implementation of the 2010 American Heart Association Guidelines for CPR were studied. METHODS: We retrospectively evaluated data on adult patients with non-traumatic deaths who had undergone manual CPR and autopsy from January 2012 to December 2014. CPR-related injuries were analyzed on autopsy records and PMCT images and compared with results of previous studies. RESULTS: In total, 180 consecutive cases were analyzed. Rib fractures and sternal fractures were most frequent (overall frequency, 66.1 and 52.8%, respectively), followed by heart injuries (12.8%) and abdominal visceral injuries (2.2%). Urgently life-threatening injuries were rare (2.8%). Older age was an independent risk factor for rib fracture [adjusted odds ratio (AOR), 1.06; 95% confidence interval (CI), 1.04-1.08; p < 0.001], ≥ 3 rib fractures (AOR, 1.06; 95% CI, 1.02-1.09; p = 0.002), and sternal fracture (AOR, 1.03; 95% CI, 1.01-1.05; p < 0.001). Female sex was significantly associated with sternal fracture (AOR, 2.08; 95% CI, 1.02-4.25; p = 0.04). Chest compression only by laypersons was inversely associated with rib and sternal fractures. Body mass index and in-hospital cardiac arrest were not significantly associated with any complications. The frequency of thoracic skeletal injuries was similar to that in recent autopsy-based studies. CONCLUSIONS: Implementation of the 2010 Guidelines had little impact on the frequency of CPR-related thoracic skeletal injuries or urgently life-threatening complications. Older age was the only independent factor related to thoracic skeletal injuries.

ABSTRACT

BACKGROUND Splenic injury is the leading cause of major bleeding after blunt abdominal trauma. We examined the clinical and radiological presentations, management, and outcome of blunt splenic injuries (BSI) in our institution. MATERIAL AND METHODS A retrospective study of BSI patients between 2011 and 2014 was conducted. We analyzed and compared management and outcome of different splenic injury grades in trauma patients. RESULTS A total of 191 BSI patients were identified with a mean (SD) age of 26.9 years (13.1); 164 (85.9%) were males. Traffic-related accident was the main mechanism of injury. Splenic contusion and hematoma (77.2%) was the most frequent finding on initial computerized tomography (CT) scans, followed by shattered spleen (11.1%), blush (11.1%), and devascularization (0.6%). Repeated CT scan revealed 3 patients with pseudoaneurysm who underwent angioembolization. Nearly a quarter of patients were managed surgically. Non-operative management failed in 1 patient who underwent splenectomy. Patients with grade V injury presented with higher mean ISS and abdominal AIS, required frequent blood transfusion, and were more likely to be FAST-positive (p=0.001). The majority of low-grade (I-III) splenic injuries were treated conservatively, while patients with high-grade (IV and V) BSI frequently required splenectomy (p=0.001). Adults were more likely to have grade I, II, and V BSI, blood transfusion, and prolonged ICU stay as compared to pediatric BSI patients. The overall mortality rate was 7.9%, which is mainly association with traumatic brain injury and hemorrhagic shock; half of the deaths occurred within the first day after injury. CONCLUSIONS Most BSI patients had grade I-III injuries that were successfully treated non-operatively, with a low failure rate. The severity of injury and presence of associated lesions should be carefully considered in developing the management plan. Thorough clinical assessment and CT scan evaluation are crucial for appropriate management of BSI.

ABSTRACT

Traumatic abdominal wall hernias due to blunt abdominal trauma in pediatric patients can pose a diagnostic challenge because of spontaneous hernia reduction. Ultrasonography may be superior to computed tomography for this indication in some cases because of the ability to dynamically and repeatedly assess the area of injury. Herniation can be induced or exaggerated via Valsalva maneuvers, which can facilitate its detection during dynamic assessment. We present the case of a 3-year-old boy who sustained blunt abdominal trauma, with a resultant abdominal wall hernia that was diagnosed using point-of-care ultrasound imaging. This hernia was not visualized with computed tomography, and point-of-care ultrasonography expedited admission for operative repair.

ABSTRACT

BACKGROUND: As a result of the current exponentially growing refugee population from the Middle-East and East Africa (Sudan, Darfur, Eritrea), clinicians (including forensic pathologists) are seeing atypical skin lesions, mainly of a traumatic nature, but in some cases associated with long-standing lesions related to ethnic practices. PATIENTS AND METHODS: A case of torture sequelae is presented herein in a patient originally from Darfur (Sudan): cutaneous incisions were made on old scars several times using a knife. DISCUSSION: The clinical presentation of scarification lesions and that of atypically healed wounds (presumably an effect of inflammation induced by the introduction of irritating foreign bodies such as sand, salt, etc.) are completely different: in all cases they indicate a relative timeframe of the facts, which the clinician should not overlook in reconstructing the patient's course and the injuries to which he has been subjected (hence the proposed designation of "palimpsest scar", in the sense that a palimpsest is a manuscript on a parchment that previously contained writing but has been scratched clean to be overwritten). Thus, a "palimpsest scar" constitutes a fresh scar on top of and hiding another (ritual) scar in a context of ethnic cleansing. The diagnostic and clinical significance comes from the importance of differentiating between ethnic-type lesions and those induced by physical violence and abuse in a context of war.

ABSTRACT

Suicide is a major public health problem around the world. Case reports include extreme suicidal self-inflicted injuries, in which extensive damage to the abdominal wall associated with injury or even excision of fragments of the intestine and its fragmentation are present. These cases usually give rise to doubts of investigators as to the course of the incident, the circumstances of death and the possibility of participation of other people. At the same time they are interesting from the medico-legal and psychiatric perspective. The aim of this study is the presentation of two extremely rare cases of suicides through evisceration and intestinal injury from the clinical and opinioning practice of the authors, one of which ended with survival and the second one with death. Regardless of the final result of the suicide attempt (death or survival), good practice of the investigative teams in such cases should include a detailed examination of the place of the suicide attempt, obtaining opinion of an expert in the field of forensic medicine with full post-mortem diagnosis, and in-depth forensic psychological and psychiatric analysis of, among others, lifeline, mental state and suicidal motivation (so-called psychological autopsy).

ABSTRACT

Veterinary pathologists commonly encounter lesions of blunt trauma. The development of lesions is affected by the object's mass, velocity, size, shape, and angle of impact and by the plasticity and mobility of the impacted organ. Scrape, impact, and pattern abrasions cause localized epidermal loss and sometimes broken hairs and implanted foreign material. Contusions are best identified after reflecting the skin, and must be differentiated from coagulopathies and livor mortis. Lacerations-traumatic tissue tears-may have irregular margins, bridging by more resilient tissue, deviation of the wound tail, crushed hairs, and unilateral abrasion. Hanging or choking can cause circumferential cervical abrasions, contusions and rupture of hairs, hyoid bone fractures, and congestion of the head. Other special forms of blunt trauma include fractured nails, pressure sores, and dog bites. Ocular blunt trauma causes extraocular and intraocular hemorrhages, proptosis, or retinal detachment. The thoracic viscera are relatively protected from blunt trauma but may develop hemorrhages in intercostal muscles, rib fractures, pulmonary or cardiac contusions or lacerations with subsequent hemothorax, pneumothorax, or cardiac arrhythmia. The abdominal wall is resilient and moveable, yet the liver and spleen are susceptible to traumatic laceration or rupture. Whereas extravasation of blood can occur after death, evidence of vital injury includes leukocyte infiltration, erythrophagocytosis, hemosiderin, reparative lesions of fibroblast proliferation, myocyte regeneration in muscle, and callus formation in bone. Understanding these processes aids in the diagnosis of blunt force trauma including estimation of the age of resulting injuries.

ABSTRACT

INTRODUCTION: Over the past two decades, there has been a shift toward non-operative treatment of patients undergoing a solid organ injury, thus requiring an increasing number of imaging studies to monitor the healing of lesions, which were performed by computed tomography (CT). In consideration of the use of ionizing radiation and contrast media, nowadays there is a trend toward the use contrast-enhanced ultrasound (CEUS) in the follow-up of blunt abdominal trauma. However CEUS has some limits, especially in the assessments of small lesions and in the evaluation of urinary tract lesions and vascular complications. Magnetic resonance imaging (MRI) is a useful alternative, since its lack of use of ionizing radiation, its panoramicity, the possibility to avoid contrast media and the ability to properly evaluate even small lesions. The aim of this study is to evaluate the usefulness and the feasibility of MRI in the follow-up of patients with low-grade blunt abdominal trauma. MATERIALS AND METHODS: We performed a retrospective review of a cohort including 270 consecutive patients with a history of blunt abdominal trauma; among them, 118 underwent a high-energy trauma, and 152 a low-energy trauma. 124 patients had findings of abdominal injuries at the contrast-enhanced multidetector CT (CE-MDCT), including 68 from the group of major trauma and 56 from the group of minor trauma. 39 patients were operated for incoming lesions. The remaining 85 patients were treated conservatively. Eight patients underwent surgery later for delayed bleeding. The remaining 77 underwent the full follow-up protocol. Follow-up protocol included CEUS at 24 and 72 h and CEUS and MRI at 1 month after trauma; only MRI was performed until the complete resolution. RESULTS: CEUS at 24-h and at 72-h from trauma showed a very good correlation with onset CE-MDCT in lesions staging. With respect to onset CE-MDCT, CEUS did not identified 2 adrenal injuries and 2 lesions of urinary tract, an intrinsic limit of this technique. CEUS performed at 1 month did not show traumatic lesions in 49/77 of patients. In the remaining 28/77 cases, CEUS demonstrated reduction of the size of the lesions ranging from 25 to 50%. MRI performed at 1 month from trauma did not show traumatic injuries in 37/77 patients; it demonstrated persistence of organ lesion in 40/77 patients. Therefore, in 12/77 patients MRI performed at 1-month demonstrated the persistence of minimal or moderate organ injury, while CEUS was completely negative. In addition, MRI allowed to enhance the persistence of adrenal lesions in 2 cases and the integrity of urinary tract in 2. In the remaining 28 patients, in which both CEUS and MRI showed disease persistence, MRI, however, allowed a better definition of injury extension with respect to CEUS, in terms of dimensions, edges, and morphological evolution. DISCUSSION AND CONCLUSIONS: MRI allowed to make a better assessment of injuries than CEUS, allowing also a temporal stage of lesions. Infact, there are different evolution stages corresponding to accurate imaging findings. To our knowledge, this is the first study that describes the evolution of blood collection in parenchymal abdominal organs. Therefore, in patients who underwent abdominal traumatic injuries conservatively treated, the follow-up at 1 month can be made by MRI, due to its panoramicity and its high contrast resolution, which allow a better morphological and temporal trauma staging respect to the CEUS.

ABSTRACT

BACKGROUND: The aim of this study was to confirm our clinical impression that intra-abdominal handlebar injuries are progressively increasing in number and severity in the latest years. METHODS: A retrospective analysis of data concerning 132 patients admitted to our department of pediatric surgery during a 10-year period (between 2003 and 2012), following bicycle-related blunt abdominal trauma, was performed. Patients were divided into two groups: those who fall from their bicycle (N.=43) and those who sustained direct impact from the handlebars (N.=89) and compared. RESULTS: Number of admitted patients due to bike related injury was increased during a 10-year period. The bikes used by 91.6% of the participants were the high quality BMX, with rigid and strong handlebars. The average age for both groups was 10.3 years (4-16 years). Boys were injured more than girls. Thirty patients from both groups sustained severe abdominal visceral injuries, 25 from the handlebar group and 6 from the fall group (P=0.018). The overall average length of hospital stay was 3.04 days, with 36 cases (27.36%) requiring pediatric intensive care unit (PICU) admission (N.=26 of the handlebar group and N.=10 of the fall group, P=0.024). Eight children sustaining handlebar injuries required abdominal surgery compared to only one case for the fall group (P=0.018), when excluding extra-abdominal procedures. CONCLUSIONS: Number of pediatric patients admitted due to bike related injury has been gradually increasing. Children who suffer from direct impact of the handlebars are more likely to require abdominal operative intervention and PICU admission than those who fall. Preventive measures are urgently needed in order to defeat this trend.

ABSTRACT

Isolated duodenal injury after blunt abdominal trauma is a very rare entity. In contrast to penetrating injuries, duodenal injuries after blunt trauma are difficult to diagnose. Early diagnosis and management is required to prevent high morbidity and mortality associated with these injuries. We present three young patients of blunt abdominal trauma with an isolated injury to duodenum in which primary repair of perforations were done with good outcomes.

ABSTRACT

Prospective investigation of the traumatic disease course was conducted in 71 injured persons, suffering a combined cranioabdominal trauma with the objective to determine the main functional systems and dynamics of their state severity. The occurrence rate and the severity degree of cardiovascular insufficiency were determined--in accordance to indices of the integrative body rheography and integrative dual frequency impedansometry, respiratory insufficiency (PaO2/FiO2 ratio), the organ insufficiency severity (in accordance to SOFA scale). There was established, that changes in respiratory and cardiovascular systems are corresponding to the staged pathogenetic characteristics of the traumatic disease periods. So on, it is expedient to perform the urgent and postponed operative interventions in a period of their relative stabilization. The presence of severe craniocerebral trauma, as a part of a combined cranioabdominal trauma causes significant and durable impairment of the functional systems activity.

ABSTRACT

The age­ and gender­related signs in 105 injured persons, who died because of combined skeletal trauma, circumstances and character of injuries, causes of death and impact of aggravating factors, were analyzed. There was established, that skeletal trauma have constituted the main cause of death in 10.48% of injured persons only, but as a component of combined injury it aggravates the traumatic disease course and, as a consequence, enhances probability of exitus lethalis. Trustworthy connection between the signs of gender, age, the injuries character and volume was established, what gives a certain information about course of traumatic disease and risk of exitus lethalis
