Imaging plays an essential part of chest trauma care. By definition, the employed imaging technique in the emergency setting should reach the correct diagnosis as fast as possible. In severe chest blunt trauma, multidetector computer tomography (MDCT) has become part of the initial workup, mainly due to its high sensitivity and diagnostic accuracy of the technique for the detection and characterization of thoracic injuries and also due to its wide availability in tertiary care centers. The aim of this paper is to review and illustrate a spectrum of characteristic MDCT findings of blunt traumatic injuries of the chest including the lungs, mediastinum, pleural space, and chest wall.

Intraosseous venous access can be life-saving in trauma patients when traditional methods for obtaining venous access are difficult or impossible. Because many blunt trauma patients require expeditious evaluation by computed tomography (CT) scans with intravenous contrast, it is important to evaluate whether intraosseous catheters can be used for administering CT contrast agents in lieu of waiting until secure peripheral intravenous or central venous catheter access can be established. Previous case reports have demonstrated that tibial intraosseous catheters can be used to safely administer CT contrast in the pediatric patient population. Here we report a case in which intraosseous access was the only means of administering intravenous contrast agent in an adult blunt trauma patient. An intraosseous catheter was placed in the standard manner in the right proximal humerus. Intravenous contrast agent was administered through the intraosseous catheter, using the standard blunt trauma protocol at our institution. CT scans were evaluated by a staff radiologist and assessed for the adequacy of diagnosis for blunt traumatic injuries. CT scans of the thorax, abdomen, and pelvis were considered to be adequate for diagnostic purposes and subjectively equivalent to those of studies using traditional central venous access. The intraosseous catheter was discontinued the following day. No complications of intraosseous placement or of contrast administration were identified. Intraosseous catheterization appears to be a feasible and effective alternative to traditional methods of venous access in the administration of iodinated contrast agents for CT evaluation in adult blunt trauma patients. Further study is warranted.

Objectives: Trauma is the greatest cause of morbidity and mortality in paediatric/adolescent populations worldwide. This study aimed to describe trauma mechanisms, patterns and outcomes among children with blunt torso trauma admitted to the Sultan Qaboos University Hospital (SQUH) in Muscat, Oman. Methods: This retrospective single-centre study involved all children ≤12 years old with blunt torso trauma admitted for paediatric surgical care at SQUH between January 2009 and December 2013. Medical records were analysed to collect demographic and clinical data. Results: A total of 70 children were admitted with blunt torso trauma during the study period, including 39 (55.7%) male patients. The mean age was 5.19 ± 2.66 years. Of the cohort, 35 children (50.0%) received their injuries after having been hit by cars as pedestrians, while 19 (27.1%) were injured by falls, 12 (17.1%) during car accidents as passengers and four (5.7%) by falling heavy objects. According to computed tomography scans, thoracic injuries were most common (65.7%), followed by abdominal injuries (42.9%). The most commonly involved solid organs were the liver (15.7%) and spleen (11.4%). The majority of the patients were managed conservatively (92.9%) with a good outcome (74.3%). The mortality rate was 7.1%. Most deaths were due to multisystem involvement. Conclusion: Among children with blunt torso trauma admitted to SQUH, the main mechanism of injury was motor vehicle accidents. As a result, parental education and enforcement of infant car seat/child seat belt laws are recommended. Conservative management was the most successful approach. PMID:27226913

Abstract We report two adult cases of congenital ureteropelvic junction obstruction detected incidentally in the setting of blunt abdominal trauma. CT images are provided to describe the presentation, while review of the literature and management of renal trauma are discussed. PMID:27579396
The aim of this study was to investigate the efficiency of domestic physician-staffed helicopter emergency medical service (HEMS) for the transport of patients with severe trauma to a hospital. The study included patients with blunt trauma who were transported to our hospital by physician-staffed HEMS (Group P; n = 100) or nonphysician-staffed HEMS (Group NP; n = 80). Basic patient characteristics, transport time, treatment procedures, and medical treatment outcomes assessed using the Trauma and Injury Severity Score (TRISS) were compared between groups. We also assessed patients who were transported to the hospital within 3 h of injury in Groups P (Group P3; n = 50) and NP (Group NP3; n = 74). The severity of injury was higher, transport time was longer, and time from hospital arrival to operation room transfer was shorter for Group P than for Group NP (P < 0.001). Although Group P patients exhibited better medical treatment outcomes compared with Group NP, the difference was not statistically significant (P = 0.134 vs. 0.730). However, the difference in outcomes was statistically significant between Groups P3 and NP3 (P = 0.035 vs. 0.546). Under the current domestic trauma patient transport system in South Korea, physician-staffed HEMS are expected to increase the survival of patients with severe trauma. In particular, better treatment outcomes are expected if dedicated trauma resuscitation teams actively intervene in the medical treatment process from the transport stage and if patients are transported to a hospital to receive definitive care within 3 hours of injury.

BACKGROUND With the use of the framework advocated by the Grading of Recommendations Assessment, Development and Evaluation (GRADE) Working Group, our aims were to perform a systematic review and to develop evidence-based recommendations that may be used to answer the following PICO [Population, Intervention, Comparator, Outcomes] question: In the obtunded adult blunt trauma patient, should cervical collar removal be performed after a negative high-quality cervical spine (C-spine) computed tomography (CT) result alone or after a negative high-quality C-spine CT result combined with adjunct imaging, to reduce peri-clearance events, such as new neurologic change, unstable C-spine injury, stable C-spine injury, need for post-clearance imaging, false-negative CT imaging result on re-review, pressure ulcers, and time to cervical collar clearance? METHODS Our protocol was registered with the PROSPERO international prospective register of systematic reviews on August 23, 2013 (Registration Number: CRD42013005461). Eligibility criteria consisted of adult blunt trauma patients 16 years or older, who underwent C-spine CT with axial thickness of less than 3 mm and who were obtunded using any definition. Quantitative synthesis via meta-analysis was not possible because of pre-post, partial-cohort, quasi-experimental study design limitations and the consequential incomplete diagnostic accuracy data. RESULTS Of five articles with a total follow-up of 1,017 included subjects, none reported new neurologic changes (paraplegia or quadriplegia) after cervical collar removal. There is a worst-case 9% (161 of 1,718 subjects in 11 studies) cumulative literature incidence of stable injuries and a 91% negative predictive value of no injury, after coupling a negative high-quality C-spine CT result with 1.5-T magnetic resonance imaging, upright x-rays, flexion-extension CT, and/or clinical follow-up. Similarly, there is a best-case 0% (0 of 1,718 subjects in 11 studies) cumulative

Deaths due to blunt force trauma to the head as a result of assault are some of the most common cases encountered by the practicing forensic pathologist. Previous studies have shown inflicting injury to the head region is one of the most effective methods of murder. The important factors that determine severity of trauma include the type of weapon used, type and site of skull fracture, intracranial haemorrhage and severity of brain injury. The aim of this study was to determine the characteristics of blunt force trauma to the skull produced by different instruments. Nine adult monkeys (Macaca fascicularis) skulls were used as models. Commonly found blunt objects comprising of Warrington hammer, hockey stick and open face helmet were used in this study. A machine calibrated force generator was used to hold the blunt object in place and to hit the skulls at forces of 12.5N and 25N. Resultant traumatic effects and fractures (linear, depressed, basilar, comminuted, and distastic) were analyzed according to type of blunt object used; surface area of contact and absolute force (N/cm(2)) delivered. Results showed that all investigated instruments were capable of producing similar injuries. The severity of trauma was not related to the surface area of contact with the blunt objects. However, only high absolute forces produced comminuted fractures. These findings were observational, as the samples were too small for statistical conclusions.

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.

Duodenal perforation after a blunt abdominal trauma is a rare emergency situation that can result in life-threatening complications. We report on a woman who had a perforation of the duodenum after a supposed mild blunt abdominal trauma. Unremarkable at the initial presentation, the patient presented with acute abdominal pain and a retroperitoneal abscess five days after the initial trauma. The duodenal repair was performed with a Roux-Y anastomosis. Difficulties in diagnosis are very common, but the early recognition of the rupture is essential. The contrast-enhanced CT scan is the gold standard for diagnosis. Surgical management depends on the severity of the trauma and must be chosen on an individual basis.

Survival following tracheoesophageal transection is uncommon. Establishing a secure airway has the highest priority in trauma management. Understanding the mechanism of the incident can be a useful adjunct in predicting the likelihood and severity of specific anatomical patterns of injuries. We discuss published literature on combined tracheoesophageal injuries after blunt neck trauma and their outcome. A search of MEDLINE for papers published regarding tracheoesophageal injury was made. The literature search identified 14 such articles referring to a total of 27 patients. Age ranged from 3-73 years. The mechanism of injury was secondary to a rope/wire in 33%, metal bar in 4% of cases and unspecified in 63%. All of the patients were managed surgically. A number of tissues were used to protect the anastomosis including pleural and sternocleidomastoid muscle flaps. There were no reported mortalities. Patients with combined tracheoesophageal injury after blunt neck trauma require acute management of airway along with concomitant occult injuries.

There have been several forensic pathological studies on the distinction between falls from height and homicidal blows in blunt head trauma, but few studies have focused on suicidal blows. Self-inflicted blunt head trauma is usually a part of a complex suicide with more than one suicidal method applied. Actually, no reports on suicide indicate blunt head trauma to be the singular cause of death in recent publications. Cases with self-inflicted blunt trauma are often challenging for those involved in the investigation because they are confronted with findings that are also found in homicides. A refined guideline to differentiate suicidal blows from homicidal blows in blunt head trauma allows for a more accurate representation of the events surrounding death. This paper presents two cases of suicide by self-inflicted blunt head trauma in which blunt head trauma from repeatedly hitting the decedent's head with a hammer was considered to be the only cause of death.

Blunt pancreatic trauma is an uncommon injury but has high morbidity and mortality. In modern era of trauma care, pancreatic trauma remains a persistent challenge to radiologists and surgeons alike. Early detection of pancreatic trauma is essential to prevent subsequent complications. However early pancreatic injury is often subtle on computed tomography (CT) and can be missed unless specifically looked for. Signs of pancreatic injury on CT include laceration, transection, bulky pancreas, heterogeneous enhancement, peripancreatic fluid and signs of pancreatitis. Pan-creatic ductal injury is a vital decision-making parameter as ductal injury is an indication for laparotomy. While lacerations involving more than half of pancreatic parenchyma are suggestive of ductal injury on CT, ductal injuries can be directly assessed on magnetic resonance imaging (MRI) or encoscopic retrograde cholangio-pancreatography. Pancreatic trauma also shows temporal evolution with increase in extent of injury with time. Hence early CT scans may underestimate the extent of injures and sequential imaging with CT or MRI is important in pancreatic trauma. Sequential imaging is also needed for successful non-operative management of pancreatic injury. Accurate early detection on initial CT and adopting a multimodality and sequential imaging strategy can improve outcome in pancreatic trauma. PMID:26981225

"War games" are gaining popularity in the western United States. These recreational contests involve members of one team attempting to shoot their opponents with high-velocity dye or paint pellets fired from air guns. Unfortunately, serious eye injuries occur when participants do not use protective eye wear. We report a case of severe blunt ocular trauma resulting in a hyphema, choroidal rupture, and retinal and vitreal hemorrhage secondary to a paint pellet striking an unprotected eye. This injury resulted in a significant visual defect in this patient.

While the neurobiology of post-traumatic stress disorder has been extensively researched, much less attention has been paid to the neural mechanisms underlying more covert but pervasive types of trauma (e.g., those involving disrupted relationships and insecure attachment). Here, we report on a neurobiological study documenting that mothers’ attachment-related trauma, when unresolved, undermines her optimal brain response to her infant’s distress. We examined the amygdala blood oxygenation level-dependent response in 42 first-time mothers as they underwent functional magnetic resonance imaging scanning, viewing happy and sad face images of their own infant, along with those of a matched unknown infant. Whereas mothers with no trauma demonstrated greater amygdala responses to the sad faces of their own infant as compared to their happy faces, mothers who were classified as having unresolved trauma in the Adult Attachment Interview (Dynamic Maturational Model) displayed blunted amygdala responses when cued by their own infants’ sadness as compared to happiness. Unknown infant faces did not elicit differential amygdala responses between the mother groups. The blunting of the amygdala response in traumatized mothers is discussed as a neural indication of mothers’ possible disengagement from infant distress, which may be part of a process linking maternal unresolved trauma and disrupted maternal caregiving.

Hollow viscus injuries of the digestive tract are an uncommon occurrence in blunt abdominal trauma. We report a 39-year-old male who was hit by a vehicle as a pedestrian and admitted to the Sultan Qaboos University Hospital, Muscat, Oman, in 2015. He underwent an exploratory laparotomy which revealed injuries to the distal stomach, liver and descending colon. Postoperatively, the patient was febrile, tachycardic and hypotensive. Abdominal examination revealed distention and tenderness. The next day, a repeat laparotomy identified a gastric injury which had not been diagnosed during the initial laparotomy. Although the defect was repaired, the patient subsequently died as a result of multiorgan failure. Missed gastric injuries are rare and are associated with a grave prognosis, particularly for trauma patients. Delays in diagnosis, in addition to associated injuries, contribute to a high mortality rate. PMID:28003902

Renal failure developed in 20 patients following blunt civilian trauma. Ten recovered normal renal function; 8 currently survive. Survivors and nonsurvivors did not differ in age, time from trauma to anuria, mean blood urea nitrogen or creatinine level prior to the first or to subsequent dialyses. However, there was an increased incidence of sepsis and liver failure in those who died. When outcome was related to site of injury, patients with closed head injury and/or intra-abdominal injury had a worse prognosis than those with thoracic or extremity injury only. Only 2 patients with perforated bowel survived; both had peritoneal dialysis combined with peritoneal lavage with antibiotic solutions. Mortality in patients with posttraumatic renal failure remains high; however, death is usually a result of associated complications rather than a result of the renal failure. Aggressive management of other complications of the trauma, especially sepsis or potential sepsis, is necessary. We recommend peritoneal dialysis combined with peritoneal antibiotic lavage where there is a potential for posttraumatic intra-abdominal sepsis associated with renal failure. PMID:843128

We report 2 cases of delayed hemothorax due to blunt chest trauma. A 48-year-old man who fell down and got a blow at the right chest had a checkup with a 1st aid outpatient. By the X-rays at the time of the 1st examination, the hemothorax was not noted. The next day, He has been transported to our hospital for atypical absence. Hemothorax was suggested by computed tomography (CT) and chest drainage was enforced. A 79-year-old man got a blow at the anterior chest by traffic accident and had a checkup in the 1st hospital. The abnormality was not recognized in the chest CT at that time. For the left hemiparesis, he was transported to our hospital the next day. Hemothorax was suggested by CT and chest drainage was enforced.

Blunt abdominal traumas are uncommonly encountered despite their high prevalence, and injuries to the organ like duodenum are relatively uncommon (occurring in only 3%-5% of abdominal injuries) because of its retroperitoneal location. Duodenal injury combined with gastric perforation from a single abdominal trauma impact is rarely heard. The aim of this case report is to present a rare case of blunt abdominal trauma with combined gastric and duodenal injuries. PMID:25738037

Blunt abdominal trauma may cause severe intra-abdominal injuries, while clinical findings could be mild or absent directly after the trauma. The absence of clinical findings could mislead physicians into underestimating the severity of the injury at the primary survey, and inevitably leads to a delay in the diagnosis. The Blunt Abdominal Trauma in Children (BATiC) score may help to identify children who are at a high risk for intra-abdominal injuries in an early stage and requires additional tests directly. A case of a 10-year-old girl with a duodenal perforation after a blunt abdominal trauma is presented. A delay in diagnosis may lead to an increased morbidity and mortality rate. A low admission threshold for children with abdominal pain after a blunt trauma is recommended.

Right atrial rupture secondary to blunt trauma is exceedingly rare. We present a case report of blunt chest trauma and right atrial rupture in a patient with a background of pericardiectomy that were successfully managed surgically. Right atrial rupture must be considered as a differential diagnosis in patients with blunt chest trauma. In patients with previous pericardiectomy, this injury may manifest with massive hemothorax, and insertion of a chest drain should be performed with extreme caution. In our experience, urgent exploratory thoracotomy and repair of the defect are the mainstays of acute management.

We present our experience with computed tomographic (CT) cystography for the diagnosis of bladder rupture in patients with blunt abdominal and pelvic trauma and compare the results of CT cystography to operative exploration. We identified all blunt trauma patients diagnosed with bladder rupture from January 1992 to September 1998. We also reviewed the radiology computerized information system (RIS) for all CT cystograms performed for the evaluation of blunt trauma during the same time period. The medical records and pertinent radiographs of the patients with bladder rupture who underwent CT cystography as part of their admission evaluation were reviewed. Operative findings were compared to radiographic findings. Altogether, 316 patients had CT cystograms as part of an initial evaluation for blunt trauma. Of these patients, 44 had an ultimate diagnosis of bladder rupture; 42 patients had CT cystograms indicating bladder rupture. A total of 28 patients underwent formal bladder exploration; 23 (82%) had operative findings that exactly (i.e., presence and type of rupture) matched the CT cystogram interpretation. The overall sensitivity and specificity of CT cystography for detection of bladder rupture were 95% and 100%, respectively. For intraperitoneal rupture, the sensitivity and specificity were 78% and 99%, respectively. CT cystography provides an expedient evaluation for bladder rupture caused by blunt trauma and has an accuracy comparable to that reported for plain film cystography. We recommend CT cystography over plain film cystography for patients undergoing CT evaluation for other blunt trauma-related injuries.

The bowel and the mesentery represent the third most frequently involved structures in blunt abdominal trauma after the liver and the spleen. Clinical assessment alone in patients with suspected intestinal and/or mesenteric injury from blunt abdominal trauma is associated with unacceptable diagnostic delays. Multi-detector computed tomography, thanks to its high spatial, time and contrast resolutions, allows a prompt identification and proper classification of such conditions. The radiologist, in fact, is asked not only to identify the signs of trauma but also to provide an indication of their clinical significance, suggesting the chance of conservative treatment in the cases of mild and moderate, non-complicated or self-limiting injuries and focusing on life-threatening conditions which may benefit from immediate surgical or interventional procedures. Specific and non-specific CT signs of bowel and mesenteric injuries from blunt abdominal trauma are reviewed in this paper.

Objective Though a number of CT findings of bowel and mesenteric injuries in blunt abdominal trauma are described in literature, no studies on the specific CT signs of a transected bowel have been published. In the present study we describe the incidence and new CT signs of bowel transection in blunt abdominal trauma. Materials and Methods We investigated the incidence of bowel transection in 513 patients admitted for blunt abdominal trauma who underwent multidetector CT (MDCT). The MDCT findings of 8 patients with a surgically proven complete bowel transection were assessed retrospectively. We report novel CT signs that are unique for transection, such as complete cutoff sign (transection of bowel loop), Janus sign (abnormal dual bowel wall enhancement, both increased and decreased), and fecal spillage. Results The incidence of bowel transection in blunt abdominal trauma was 1.56%. In eight cases of bowel transection, percentage of CT signs unique for bowel transection were as follows: complete cutoff in 8 (100%), Janus sign in 6 (100%, excluding duodenal injury), and fecal spillage in 2 (25%). The combination of complete cutoff and Janus sign were highly specific findings in patients with bowel transection. Conclusion Complete cut off and Janus sign are the unique CT findings to help detect bowel transection in blunt abdominal trauma and recognition of these findings enables an accurate and prompt diagnosis for emergency laparotomy leading to reduced mortality and morbidity.

To determine the effect of admission body weight on blunt trauma victims, a chart review of all patients greater than 12 years of age admitted to Sentara Norfolk General Hospital between January 1 and July 31, 1987 was undertaken. The charts of 351 patients were reviewed; 184 records contained admission height and weight. These 184 patients made up the study group and age, gender, injuries, Injury Severity Score (ISS), ventilator days (VD), complications, length of stay (LOS), and outcome were noted. Body Mass Index (BMI) (weight (kg)/(height(m))2, was calculated for each patient. The average ISS was 21.87 (range, 1-66) and the average BMI was 25.15 kg/m2 (range, 16-46 kg/m2). The overall mortality for the population was 9%. The population was grouped according to BMI: average (less than 27 kg/m2), overweight (27-31 kg/m2), and severely overweight (greater than 31 kg/m2). The mortality of 5.0% and 8.0% in the average and overweight groups was not different. The severely overweight group had a higher mortality at 42.1% compared with the other two groups (p less than 0.0001). The groups did not differ in age, ISS, LOS, nor VD. Age, BMI, and ISS were subjected to regression analysis. By this method BMI and ISS were independent determinants of outcome (p less than 0.0001). There was an increase in complications, mainly pulmonary problems, in the SO group (p less than 0.05). The three groups were subdivided into survivors and nonsurvivors. The nonsurvivors had a longer average LOS at 26.6 days compared with nonsurvivors in the overweight (5.0 days) or severely overweight (8.62 days) groups (p less than 0.007). The severely group was characterized by a rapid deterioration and demise that was unresponsive to intervention. ISS did not differ among nonsuvivors. Among survivors the severely overweight group had a lower ISS, 9.73. This was different from the overweight group (21.57) and from the average group (20.21) (p less than 0.04).

The diagnosis of blunt injury to the gallbladder may constitute a significant challenge to the diagnostician. There is often a delay in presentation with non-specific clinical symptoms. In the absence of reliable clinical symptoms, diagnostic imaging becomes an invaluable tool in the rapid identification of gallbladder injury. We present a case of isolated gallbladder injury following blunt abdominal trauma which was diagnosed by computed tomography and subsequently confirmed by cholecystectomy.

The incidence of pancreatic injury following blunt abdominal trauma is rare. A timely accurate diagnosis of such injury is difficult and also the management remains controversial. Here, we reported the successful use of laparoscopy to diagnose, characterize and treat blunt pancreatic trauma in a 28-year-old male patient involved in a motor vehicle crash. An abdominal computed tomography scan showed peripancreatic fat stranding suggestive of pancreatic injury. With persistent clinical signs of peritonitis and laboratory investigations suggestive of pancreatitis, the patient underwent laparoscopic drainage of the lesser sac. The patient had an uneventful postoperative course. The management of patients with blunt pancreatic injuries should be tailored to individual situations. Our experience suggests that a timely laparoscopic management of traumatic pancreatic injury is safe approach in selected cases.

The present photocase illustrates the possible mechanism of direct cardiac injuries from broken sharp jagged fractured ends of ribs in blunt force trauma to the chest in run over traffic mishaps. We propose that the projecting fractured ends of the ribs penetrate the underlying thoracic organs due to the transient phenomenon of deformation of chest cavity under pressure in run over traffic mishaps.

Diagnostic procedures such as peritoneal lavage, computed tomography, emergency angiography, nuclear scintigraphy, and contrast studies of the gastrointestinal and urinary tracts can assist in the identification, quantification, and localization of injury after blunt abdominal trauma. Use of these procedures should be determined by careful clinically assessment as part of an aggressive approach to the diagnosis of the injured patient. 22 references.

Background. Blunt chest wall trauma accounts for over 10% of all trauma patients presenting to emergency departments worldwide. When the injury is not as severe, deciding which blunt chest wall trauma patients require a higher level of clinical input can be difficult. We hypothesized that patient factors, injury patterns, analgesia, postural condition, and positive airway pressure influence outcomes. Methods. The study population consisted of patients hospitalized with at least 3 rib fractures (RF) and at least one pulmonary contusion and/or at least one pneumothorax lower than 2 cm. Results. A total of 140 patients were retrospectively analyzed. Ten patients (7.1%) were admitted to intensive care unit (ICU) within the first 72 hours, because of deterioration of the clinical conditions and gas exchange with worsening of chest X-ray/thoracic ultrasound/chest computed tomography. On univariable analysis and multivariable analysis, obliged orthopnea (p = 0.0018) and the severity of trauma score (p < 0.0002) were associated with admission to ICU. Conclusions. Obliged orthopnea was an independent predictor of ICU admission among patients incurring non-life-threatening blunt chest wall trauma. The main therapeutic approach associated with improved outcome is the prevention of pulmonary infections due to reduced tidal volume, namely, upright postural condition and positive airway pressure.

Although the exact benefit of adjunctive splenic artery embolization (SAE) in the nonoperative management (NOM) of patients with blunt splenic trauma has been debated, the role of transcatheter embolization in delayed splenic hemorrhage is rarely addressed. The purpose of this study was to evaluate the effectiveness of SAE in the management of patients who presented at least 3 days after initial splenic trauma with delayed hemorrhage. During a 24-month period 4 patients (all male; ages 19-49 years) presented with acute onset of pain 5-70 days after blunt trauma to the left upper quadrant. Two had known splenic injuries that had been managed nonoperatively. All had computed axial tomography evidence of active splenic hemorrhage or false aneurysm on representation. All underwent successful SAE. Follow-up ranged from 28 to 370 days. These cases and a review of the literature indicate that SAE is safe and effective for NOM failure caused by delayed manifestations of splenic arterial injury.

In this paper we present a unique pattern of blunt force cranial trauma that was observed in 10 of a sample of 85 crania from a Cambodian skeletal collection comprised of Khmer Rouge victims. Initial examination of the trauma, which presents as substantial damage to the occipital with fractures extending to the cranial base, suggested the pattern was classifiable as a basilar or ring fracture. However, further investigation, including trauma analysis and historical research, revealed that this fracture type is distinctive from basilar and ring fractures. Historical data indicate that a particular execution method was the likely source of the trauma. Recognition of this trauma pattern is significant because it exemplifies the distinct fracture configuration resulting from an apparently categorical and methodical execution technique. Identification of this fracture type could potentially assist forensic investigators in the recognition of specific methods of murder or execution.

Background: In stable patients with blunt abdominal trauma, accurate diagnosis of visceral injuries is crucial. Objectives: To determine whether repeating ultrasound exam will increase the sensitivity of focused abdominal sonography for trauma (FAST) through revealing additional free intraperitoneal fluid in patients with blunt abdominal trauma. Patients and Methods: We performed a prospective observational study by performing primary and secondary ultrasound exams in blunt abdominal trauma patients. All ultrasound exams were performed by four radiology residents who had the experience of more than 400 FAST exams. Five routine intraperitoneal spaces as well as the interloop space were examined by ultrasound in order to find free fluid. All patients who expired or were transferred to the operating room before the second exam were excluded from the study. All positive ultrasound results were compared with intra-operative and computed tomography (CT) findings and/or the clinical status of the patients. Results: Primary ultrasound was performed in 372 patients; 61 of them did not undergo secondary ultrasound exam; thus, were excluded from the study.Three hundred eleven patients underwent both primary and secondary ultrasound exams. One hundred and two of all patients were evaluated by contrast enhanced CT scan and 31 underwent laparotomy. The sensitivity of ultrasound exam in detecting intraperitoneal fluid significantly increased from 70.7% for the primary exam to 92.7% for the secondary exam. Examining the interloop space significantly improved the sensitivity of ultrasonography in both primary (from 36.6% to 70.7%) and secondary (from 65.9% to 92.7%) exams. Conclusions: Performing a secondary ultrasound exam in stable blunt abdominal trauma patients and adding interloop space scan to the routine FAST exam significantly increases the sensitivity of ultrasound in detecting intraperitoneal free fluid.

Background Although relatively rare, blunt injury to thoracic great vessels is the second most common cause of trauma related death after head injury. Over the last twenty years, the paradigm for management of these devastating injuries has changed drastically. The goal of this review is to update the reader on current concepts of diagnosis and management of blunt thoracic vascular trauma. Methods A review of the medical literature was performed to obtain articles pertaining to both blunt injuries of the thoracic aorta and of the non-aortic great vessels in the chest. Articles were chosen based on authors' preference and clinical expertise. Discussion Blunt thoracic vascular injury remains highly lethal, with most victims dying prior to reaching a hospital. Those arriving in extremis require immediate intervention, which may include treatment of other associated life threatening injuries. More stable injuries can often be medically temporized in order to optimize definitive management. Endovascular techniques are being employed with increasing frequency and can often significantly simplify management in otherwise very complex patient scenarios. PMID:19751511

Traumatic rupture of intracardiac structures is an uncommon phenomenon although there are a number of reports with regards to rupture of the tricuspid, mitral and aortic valves. We report the case of a 25-year-old patient who presented with acute aortic and mitral valve regurgitation of traumatic origin. Both lesions were seen separated by 2 weeks. Pathophysiology is reviewed. The combination of both aortic and mitral lesions following blunt chest trauma is almost exceptional.

Objective The objective of this study was to determine if the white blood cell count can predict severity of injury in blunt trauma victims. Methods This was a retrospective study comparing two groups of blunt trauma victims by severity of injury, one with significant injury and one without significant injury, and comparing their initial WBC in the emergency department (ED). We also examined if WBC correlates with degree of injury using Injury Severity Score (ISS) in both groups combined. Further, we examined the WBC as a predictor of serious injury. Results Our study showed a difference in mean WBC between the two groups that was statistically significant (p<0.001). A positive relationship between ISS and WBC was found, although the association was weak (correlation coefficient = 0.369). While the WBC had moderate discriminatory capability for serious injury, it could not, in isolation, reliably rule in or out serious injury. Nevertheless, this study supports using WBC on presentation to the ED as an adjunct for making disposition decisions. Conclusion A significant elevation in WBC in a blunt trauma patient, even with minimal initial signs of severe injury, should heighten suspicion for occult injury. PMID:19561712

ABSTRACT Gallbladder rupture following blunt abdominal trauma is a rare event recognized on evaluation and treatment of other visceral injuries during laparotomy. Isolated gallbladder rupture secondary to blunt abdominal trauma is even more uncommon. The clinical presentation of gallbladder injury is variable, resulting in a delay in diagnosis and treatment. We report the case of a patient who suffered an isolated gallbladder rupture due to blunt abdominal trauma. PMID:23843066

Background Traumatic perforation of the distal oesophagus due to blunt trauma is a very rare condition and is still associated with a significant morbidity and mortality. This is further exacerbated by delayed diagnosis and management as symptoms and signs are often masked by or ascribed to more common blunt thoracic injuries. Case report We present a case of a distal oesophageal perforation, secondary to a fall from a third storey window, which was masked by concomitant thoracic injuries and missed on both computed tomography imaging and laparotomy. The delay in his diagnosis significantly worsened the patient's recovery by allowing the development of an overwhelming chest sepsis that contributed to his death. Conclusion Early identification of an intrathoracic oesophageal perforation requires deliberate consideration and is essential to ensure a favorable outcome. Treatment should be individualised taking into account the nature of the oesophageal defect, time elapsed from injury and the patient's general condition. PMID:17374175

During the 5-year period from January 1978 through December 1982, 196 patients with blunt trauma to the small bowel, colon, or mesentery were treated at the Maryland Institute for Emergency Medical Services Systems (MIEMSS) Shock Trauma Center. More than 80% of these patients were the victims of motor vehicle accidents and therefore commonly had multisystem injuries. Sixty of these patients suffered 83 major injuries in the form of perforation or mesenteric injury resulting in ischemic bowel. This group accounted for 6.9% of the 870 patients who had celiotomy for blunt trauma during this period. Several significant observations were made. All injuries, except one, were diagnosed by peritoneal lavage. Only two duodenal injuries were present. Perforations involving the jejunum and ileum were distributed throughout the entire length of the small bowel. Colon injuries comprised one-fourth of the major injuries, with most occurring in the ascending and sigmoid colon. There were 16 deaths, 6 of which occurred as a result of complications from the bowel injury. PMID:3970600
Behind Armour Blunt Trauma (BABT) is the non-penetrating injury resulting from the rapid deformation of armours covering the body. The deformation of the surface of an armour in contact with the body wall arises from the impact of a bullet or other projectile on its front face. The deformation is part of the retardation and energy absorbing process that captures the projectile. In extreme circumstances, the BABT may result in death, even though the projectile has not perforated the armour. An escalation of the available energy of bullets and the desire of armour designers to minimise the weight and bulk of personal armour systems will increase the risk of BABT in military and security forces personnel. In order to develop materials that can be interposed between the armour and the body wall to attenuate the transfer of energy into the body, it is essential that the mechanism of BABT is known. There is a great deal of activity within UK and NATO to unravel the interactions; the mechanism is likely to be a combination of stress (pressure) waves generated by the rapid initial motion of the rear of the armour, and shear deformation to viscera produced by gross deflection of the body wall. Physical and computer model systems are under development to characterise the biophysical processes and provide performance targets for materials to be placed between armours and the body wall in order to attenuate the injuries (trauma attenuating backings-TABs). The patho-physiological consequences of BABT are being clarified by research, but the injuries will have some of the features of blunt chest trauma observed in road traffic accidents and other forms of civilian blunt impact injury. The injuries also have characteristics of primary blast injury. An overview diagnosis and treatment is described.

Duodenal rupture secondary to blunt trauma is a relatively uncommon event and is usually a result of a road traffic accident. As the duodenum is a retroperitoneal organ, delays in diagnosis can occur, as the patient may present with vague abdominal symptoms and other non-specific signs. Computed tomographic scanning is therefore a useful tool in the diagnosis of this condition. We present a 19-year-old girl who was hit in the abdomen with a football and subsequently had a duodenal rupture.

Esophageal injury following blunt trauma to chest is an extremely rare event, with only a limited number of cases being reported in the world literature. We report a case of perforation of the lower thoracic esophagus following a crush injury to the chest in a 14 year old child. An appropriately placed chest drain and decompression gastrostomy resulted in complete resolution of the esophageal leak within four weeks. This case report demonstrates that a conservative approach to lower thoracic esophageal perforations can be carried out successfully without the added morbidity of thoracotomy and risks of direct repair.

Blunt liver trauma is the most dangerous and the second most frequent solid organ trauma that occurs in the abdominal cavity. Management of this life-threatening situation remains a significant challenge. The present study identified that the patterns of blunt liver trauma were closely correlated with the characteristics of the blunt force. Illustrations of findings from this study have been included in the hope that they may aid surgeons in improving the management of this emergency. In total, 53 cases of blunt liver trauma that underwent laparotomy in the First Affiliated Hospital of Wenzhou Medical College between 1999 and 2009 were retrospectively studied. The cause of the injury, the direction and site of the blunt force, surgical records and CT films were carefully studied to obtain information on the patterns and severity of the liver injury and the correlation with blunt forces. Trauma in the right lobe of the liver was mainly caused by acceleration, deceleration and compression of the liver, while in the left lobe of the liver, acceleration was the main cause of the trauma. Liver lacerations were always located close to the attachment sites of the ligaments which bore the majority of the shearing stress. The characteristics of the blunt force play a key role in the different patterns of blunt liver trauma. A thorough understanding of the mechanisms of blunt liver trauma may aid doctors in the management of patients with this condition.

Purpose To evaluate outer retinal structural abnormalities in patients with visual deficits following closed globe blunt ocular trauma (cgBOT). Methods Nine subjects with visual complaints following cgBOT were examined between 1 month post-trauma and 6 years post-trauma. Spectral domain optical coherence tomography (SD-OCT) was used to assess outer retinal architecture, while adaptive optics scanning light ophthalmoscopy (AOSLO) was used to analyze photoreceptor mosaic integrity. Results Visual deficits ranged from central scotomas to decreased visual acuity. SD-OCT defects included focal foveal photoreceptor lesions, variable attenuation of the interdigitation zone, and mottling of the outer segment band, with one subject having normal outer retinal structure. AOSLO revealed disruption of the photoreceptor mosaic in all subjects, variably manifesting as foveal focal discontinuities, perifoveal hyporeflective cones, and paracentral regions of selective cone loss. Conclusions We observe persistent outer retinal disruption in subjects with visual complaints following cgBOT, albeit to a variable degree. AOSLO imaging allows assessment of photoreceptor structure at a level of detail not resolvable using SD-OCT or other current clinical imaging tools. Multimodal imaging appears useful for revealing the cause of visual complaints in patients following cgBOT. Future studies are needed to better understand how photoreceptor structure changes longitudinally in response to various trauma. PMID:24752010

Chest trauma has a significant relevance on outcome after severe trauma. Clinically, impaired lung function typically occurs within 72 hours after trauma. However, the underlying pathophysiological mechanisms are still not fully elucidated. Therefore, we aimed to establish an experimental long-term model to investigate physiological, morphologic and inflammatory changes, after severe trauma. Male pigs (sus scrofa) sustained severe trauma (including unilateral chest trauma, femur fracture, liver laceration and hemorrhagic shock). Additionally, non-injured animals served as sham controls. Chest trauma resulted in severe lung damage on both CT and histological analyses. Furthermore, severe inflammation with a systemic increase of IL-6 (p = 0.0305) and a local increase of IL-8 in BAL (p = 0.0009) was observed. The pO2/FiO2 ratio in trauma animals decreased over the observation period (p < 0.0001) but not in the sham group (p = 0.2967). Electrical Impedance Tomography (EIT) revealed differences between the traumatized and healthy lung (p < 0.0001). In conclusion, a clinically relevant, long-term model of blunt chest trauma with concomitant injuries has been developed. This reproducible model allows to examine local and systemic consequences of trauma and is valid for investigation of potential diagnostic or therapeutic options. In this context, EIT might represent a radiation-free method for bedside diagnostics. PMID:28000769

Blunt laryngotracheal trauma can be a life-threatening event. Two cases of isolated blunt laryngotracheal trauma in pediatric patients are presented. One case involves a 12-year-old mate who suffered isolated tracheal trauma from a fall. He developed respiratory distress and required a tracheostomy. Intraoperatively he was noted to have a thyroid cartilage fracture. The other case involves a 14-year-old female who was kicked in the neck by a horse. After unsuccessful intubation attempts that completed a tracheal transection, she required an emergency cricothyrotomy and a subsequent tracheostomy. The diagnosis, differential diagnosis, associated injuries, and treatment options for blunt laryngeal trauma are reviewed.

A 21 year-old woman was admitted to our hospital because of chest and back pain after blunt chest trauma. On admission, consciousness was clear and a physical examination showed labored breathing. Her vital signs were stable, but her breathing gradually worsened, and artificial respiration was started. The chest roentgenogram and a subsequent chest computed tomographic scans revealed contusions, hemothorax of the left lung and multiple rib fractures. A transthoracic echocardiography (TTE) revealed normal left ventricular wall motion and mild mitral regurgitation (MR). TTE was carried out repeatedly, and revealed gradually progressive MR and prolapse of the posterior medial leaflet, although there was no congestive heart failure. After her general condition had recovered, surgery was performed. Intraoperative transesophageal echocardiography (TEE) revealed torn chordae at the posterior medial leaflet. The leaflet where the chorda was torn was cut and plicated, and posterior mitral annuloplasty was performed using a prosthetic ring. One month later following discharge, the MR had disappeared on TTE.

Sternal fractures caused by blunt chest trauma are associated with an increased incidence of cardiac injury. Reports of the incidence of cardiac injury associated with sternal fracture range from 18% to 62%. Delayed cardiac tamponade is a rare phenomenon that appears days or weeks after injury. Moreover, after nonpenetrating chest trauma, cardiac tamponade is very rare and occurs in less than 1 of 1000. This case describes a patient who had delayed cardiac tamponade 17 days after a severe blunt chest trauma.

Rupture of the membranous septum is a very rare complication of blunt chest trauma. In this report, we describe a 22-year-old man who sustained multiple blunt trauma injuries during a motor vehicle accident. Rupture of the membranous septum was diagnosed 48 hours after the initial trauma and the defect was closed with Gore-Tex (W.L. Gore & Assoc, Flagstaff, AZ). However, the operation was complicated by complete atrioventricular block requiring implantation of a permanent DDD pacemaker.

Purpose. To evaluate the oxygen saturation in retinal blood vessels in patients after closed-globe blunt ocular trauma. Design. Retrospective observational case series. Methods. Retinal oximetry was performed in both eyes of 29 patients with unilateral closed-globe blunt ocular trauma. Arterial oxygen saturation (SaO2), venous oxygen saturation (SvO2), arteriovenous difference in oxygen saturation (SO2), arteriolar diameter, venular diameter, and arteriovenous difference in diameter were measured. Association parameters including age, finger pulse oximetry, systolic pressure, diastolic pressure, and heart rate were analyzed. Results. The mean SaO2 in traumatic eyes (98.1% ± 6.8%) was not significantly different from SaO2 in unaffected ones (95.3% ± 7.2%) (p = 0.136). Mean SvO2 in traumatic eyes (57.1% ± 10.6%) was significantly lower than in unaffected ones (62.3% ± 8.4%) (p = 0.044). The arteriovenous difference in SO2 in traumatic eyes (41.0% ± 11.2%) was significantly larger than in unaffected ones (33.0% ± 6.9%) (p = 0.002). No significant difference was observed between traumatic eyes and unaffected ones in arteriolar (p = 0.249) and venular diameter (p = 0.972) as well as arteriovenous difference in diameter (p = 0.275). Conclusions. Oxygen consumption is increased in eyes after cgBOT, associated with lower SvO2 and enlarged arteriovenous difference in SO2 but not with changes in diameter of retinal vessels.

A best evidence topic in cardiothoracic surgery was written according to a structured protocol. The question addressed was whether there is any role for resuscitative emergency department thoracotomy in severe blunt trauma. Emergency thoracotomy is an accepted intervention for patients with penetrating cardiothoracic trauma. However, its role in blunt trauma has been challenged and has been a subject of considerable debate. Altogether, 186 relevant papers were identified, of which 14 represented the best evidence to answer the question. The author, journal, date, country of publication and relevant outcomes are tabulated. The 14 studies comprised 2 systematic reviews and 12 retrospective studies. The systematic review performed by the Trauma Committee of the American College of Surgeons included 42 studies and a cumulative total of 2193 blunt trauma patients who underwent an emergency department thoracotomy, reporting a survival rate of 1.6%. According to this review, 15% of the survivors suffered from neurological sequelae, but survivors from both penetrating and blunt trauma were included. A systematic review comprising 24 studies reported a survival rate of 1.4% among 1047 blunt trauma patients. Of the retrospective studies, 11 report poor survival rates, ranging from 0 to 6%. Only one study reports a higher survival rate (12.2%). Five of the studies reported on the neurological outcome of survivors. The majority of the studies suffered from limitations due to the small number of included cases. The reported survival after an emergency department thoracotomy for blunt trauma is very low in the vast majority of available studies. Furthermore, the neurological sequelae in the few survivors are frequent and severe. Interestingly, some author groups recommend that emergency department thoracotomy should be contraindicated in cases of blunt trauma with no signs of life at the scene of trauma or on arrival at the emergency department. Larger, well-designed series will

The long-term consequences of blunt renal trauma are not well described. We report on 2 patients with a history of blunt renal trauma who presented with radiographically detected renal masses suspicious for renal tumor. Both patients suffered blows to the kidney during boxing matches followed by flank pain and hematuria. The injuries occurred 25 and 50 years prior to the detection of renal masses. Subsequent nephrectomy and histopathological evaluation revealed benign dystrophic renal tissue. These presentations represent probable long-term sequelae of blunt renal trauma.

Blunt trauma to the temporal region can cause fracture of the skull base, loss of hearing, vestibular symptoms and otorrhoea. The most common causes of blunt trauma to the ear and surrounding area are motor vehicle accidents, violent encounters, and sports-related accidents. We present an obscure case of a man who was struck in the ear by a flying fish while wading in the sea with resulting temporal bone fracture, sudden deafness, vertigo, cerebrospinal fluid otorrhoea, and pneumocephalus.

Traumatic perforation of the cervical esophagus due to blunt trauma is a very rare condition which continues to be associated with significant mortality rates. The symptoms and signs of this injury are often masked by or ascribed to more common blunt thoracic injuries. This paper presents a case of cervical esophageal perforation secondary to blunt trauma resulting from a car accident. The injury was diagnosed early by computed tomography examination, and the patient underwent prompt and successful surgical repair performed to prevent the development of descending mediastinitis.

Gall bladder injuries are seen in 2% of patients undergoing laparotomy for blunt trauma abdomen. Isolated gall bladder injury is a rare event with associated presence of stones is even rarer. The associated visceral injuries lead to intraoperative identification in most cases. Here we present a case of 30 years old male with isolated gall bladder laceration following blunt abdominal trauma. The diagnosis of gallbladder perforation after blunt injury may be suspected in patients with signs of an acute abdomen and hypotension that is not explained by blood loss. Early suspicion and prompt exploration is imperative. Cholecystectomy is an adequate treatment for the condition.

We report the experience of a Level I trauma center in the management of blunt renal injury during a 5-year period, with special attention to those treated using angiography with embolization. The institutional trauma registry was queried for all patients with blunt renal injury between September 1, 2009 and August 30, 2014. Each injury was graded using the American Association for the Surgery of Trauma guidelines. Patients that underwent angiography with embolization were reviewed for case-specific information including imaging findings, treatment, materials used, clinical course, and mortality. The registry identified 48 blunt renal injury patients. Median Injury Severity Score was higher and hospital length of stay was significantly longer in those with blunt renal injury when compared with those without blunt renal injury (P < 0.001). The majority of patients with blunt renal injury were managed nonoperatively. Mortality was three out of 48 patients (5%). Nine patients underwent exploratory laparotomy. These operations were always performed for reasons other than the renal trauma (e.g., splenic injury, free fluid, free air). No patient underwent invasive renal operation. Six patients were treated using angiography with embolization. Of the six, one patient died of pulmonary septic complications. We conclude that selective nonoperative management is the mainstay of treatment for blunt renal injury. Angiography with embolization is a useful modality for cases of ongoing bleeding, and is typically preferable to nephrectomy in our experience.

Blunt thoracic trauma is a common occurrence in automobile accidents. Acute myocardial infarction (AMI) caused by coronary dissection following blunt thoracic trauma is rare. We report a case of healthy 24-year-old man with a history of blunt thoracic injury with subsequent undetected AMI who died of acute decompensated heart failure 4 days after the insult. The autopsy findings showed a 90% luminal narrowing of the left anterior descending coronary artery by dissecting hematoma, 3 cm in length. The myocardium revealed transmural myocardial infarction affecting apex, most part of left ventricular free wall, and interventricular septum. Both lungs were heavy, wet, and noncrepitant. Histological findings of the infarcted myocardium were consistent with 3-5 days post-AMI. Sections from both lungs revealed massive pulmonary edema, reflecting acute decompensated heart failure following a large AMI secondary to coronary dissection. Blunt thoracic trauma may obscure typical chest pain associated with cardiac ischemia especially in cases with a high tolerance for pain.
We report the case of a 69-year-old male patient who appeared in our clinic with persistent swelling on the right middle nasal bridge of 3 months' standing following blunt trauma. On physical examination the swelling was pulsatile and a flow was identified on color Doppler sonography. MRT of the head demonstrated an aneurysm of the dorsal nasal artery. We treated the aneurysm in an open surgical procedure under local anaesthesia. Due to the superficial position of this artery, open injuries are common after blunt nasal trauma. Some cases of aneurysm of the temporal artery have been described. Aneurysm of the dorsal nasal artery is a rare result of nasal trauma.

Gastrointestinal hollow viscus injury after blunt chest and abdominal trauma is uncommon and complicates 0.6%-1.2% of all cases of trauma. Early recognition of such injuries significantly decreases morbidity and mortality. Since physical examination is not accurate in detecting such injuries, contrast-enhanced computed tomography has been the mainstay for diagnosis in many emergency departments. This pictorial essay aims to review the incidence, mechanisms, and signs of gastrointestinal hollow viscus injuries in the setting of blunt chest and abdominal trauma.

Since the advent of percutaneous cardiopulmonary support (PCPS), its application has been extended to massively injured patient. Cardiac injury following blunt chest trauma brings out high mortality and morbidity. In our cases, patients had high injury severity score by blunt trauma and presented sudden hemodynamic collapse in emergency room. We quickly detected cardiac tamponade by focused assessment with sonography for trauma and implemented PCPS. As PCPS established, their vital sign restored and then, they were transferred to the operation room (OR) securely. After all injured lesion repaired, PCPS weaned successfully in OR. They were discharged without complication on day 26 and 55, retrospectively. PMID:23130310

Trauma is the third most common cause of death in the West. In the US, approximately 90,000 deaths annually are traumatic in nature and over 75% of casualties from blunt trauma are due to chest injuries. Cardiac injuries from rib fractures following blunt trauma are extremely rare. We report the unusual case of a patient who fell from a height and presented with haemopericardium and haemothorax as a result of left ventricular and lingular lacerations and was sucessfully operated upon.

A 65-year-old male developed acute myocardial infarction due to coronary artery dissection and tricuspid valve injury after blunt chest trauma. Acute myocardial infarction was treated by coronary artery intervention; however, refractory heart failure with pleural effusion remained. The first transthoracic echocardiography (TTE) on admission failed to clearly visualize the tricuspid valve and right ventricle due to poor image quality. A follow-up TTE with contrast ultrasonography revealed pericardial rupture in addition to tricuspid regurgitation. Ruptures of the tricuspid papillary muscle and pericardium were confirmed during surgery and were repaired successfully. Blunt chest trauma results in various cardiac injuries including cardiac rupture, intramural hematoma, valvular injury, coronary artery injury, and electrical disturbances, leading to critical conditions and high mortality. Of such blunt trauma-induced injuries, coronary artery dissection, tricuspid valve injury, and pericardial rupture caused by blunt chest trauma are rare, and simultaneous occurrence of the three types of injuries that were successfully repaired has not been reported. In addition, this case indicates the utility of contrast ultrasonography for diagnosis of pericardial rupture caused by blunt chest trauma.

Testicular rupture, one of the most common complications in blunt scrotal trauma, is the rupture of tunica albuginea and extrusion of seminiferous tubules. Testicular rupture is more inclined to young men, and injury mechanisms are associated with sports and motor accidents. After history taking and essential physical examination, scrotal ultrasound is the first-line auxiliary examination. MRI is also one of the vital complementary examinations to evaluate testicular rupture after blunt scrotal trauma. Surgical exploration and repair may be necessary when the diagnosis of testicular rupture is definite or suspicious. Postoperative follow-up is to monitor the relief of local symptoms and changes of testicular functions. This review sums up the literatures about testicular rupture after blunt scrotal trauma in recent 16 years and also refers some new advantages and perspectives on diagnosis and management of testicular rupture.

Purpose This study aims to examine the current management strategies and outcomes after blunt pancreatic trauma in children using a national patient registry. Methods Using the National Trauma Data Bank (NTDB) from 2007–2011, we identified all patients ≤18 years old who suffered blunt pancreatic trauma. Patients were categorized as undergoing nonoperative pancreatic management (no abdominal operation, abdominal operation without pancreatic-specific procedure, or pancreatic drainage alone) or operative pancreatic management (pancreatic resection/repair). Patient characteristics, operative details, clinical outcomes, and factors associated with operative management were examined. Results Of 610,402 pediatric cases in the NTDB, 1653 children (0.3%) had blunt pancreatic injury and 674 had information on specific location of pancreatic injury. Of these 674 cases, 514 (76.3%) underwent nonoperative pancreatic management. The groups were similar in age, gender, and race; however, pancreatic injury grade > 3, moderate to severe injury severity, and bicycle accidents were associated with operative management in multivariable analysis. Children with pancreatic head injuries or GCS motor score < 6 were less likely to undergo pancreatic operation. Overall morbidity and mortality rates were 26.5% and 5.3%, respectively. Most outcomes were similar between treatment groups, including mortality (2.5% vs. 6.7% in operative vs. nonoperative cohorts respectively; p = 0.07). Conclusion Although rare, blunt pancreatic trauma in children continues to be a morbid injury. In the largest analysis of blunt pancreatic trauma in children, we provide data on which to base future prospective studies. Operative management of pancreatic trauma occurs most often in children with distal ductal injuries, suggesting that prospective studies may want to focus on this group. PMID:27577183

Renal artery pseudoaneurysm is a very rare complication after blunt trauma injury. We report on a case of a 54-year-old man admitted to our hospital for right flank pain and gross hematuria, 5 days after blunt abdominal trauma. The diagnosis of interlobar renal pseudoaneurysm was established by a computed tomography scan and confirmed by angiography. Successful superselective angioembolization was performed. This radiographic intervention is an effective and minimally invasive technique to stop active bleeding from renal artery pseudoaneurysms, when patients are hemodynamically stable and where technically feasible. A review of the literature was carried out. PMID:24809039

The spleen is the most commonly injured abdominal organ in children who sustain blunt abdominal trauma, and pediatric splenic injury may result from minor mechanisms of injury, including sports participation. We present 2 cases of splenic injury in soccer goalies because of blunt abdominal trauma sustained during game play. Although abdominal organ injuries are uncommon in soccer, emergency medicine and primary care physicians must be aware of the possibility. A high index of suspicion and careful physical examination are key in making the diagnosis.

Pediatric laryngotracheal injuries from blunt neck trauma are extremely rare, but can be potentially catastrophic. Early diagnosis and skillful airway management is critical in avoiding significant morbidity and mortality associated with these cases. We present a case of a patient who suffered a complete tracheal transection and cervical spine fracture following a clothesline injury to the anterior neck. A review of the mechanisms of injury, clinical presentation, initial airway management, and anesthetic considerations in laryngotracheal injuries from blunt neck trauma in children are presented.

Blunt cerebrovascular injuries (BCVI) carry significant morbidity if not diagnosed and treated early. A high index of clinical suspicion is needed to recognize the injury patterns associated with this condition and to order the requisite imaging studies needed to diagnose it accurately. We report of BCVI associated with a congenital cervical spine malformation after blunt trauma. We recommend inclusion of cervical spine malformations to the current Eastern Association for the Surgery of Trauma screening criteria for BCVI and explain our rationale for the same.

Serious blunt scrotal trauma in the pediatric population is rare and can pose significant danger to the viability of the testes. The following case describes an adolescent boy who presented with a single testis in his scrotum after low-impact perineal trauma, consistent with testicular dislocation. The literature regarding scrotal trauma includes few cases of testicular dislocation from low-impact perineal trauma. Included is a brief review of the most recent data including epidemiology, differential diagnosis, acute management, and complications pertinent to the pediatric emergency clinician.

Introduction Soft tissue injuries are relatively common after blunt neck trauma, because of its complex anatomy, many vital structures can be compromised. Isolated trauma to the thyroid is highly uncommon and there are few cases reported in the literature. Presentation of case A 19 year-old female patient with no known pathologies who sustained direct blunt trauma to the right frontal half of the neck after falling down from a stair case. She arrived at the ER with moderate neck swelling and pain. There were no visible hematomas and no respiratory compromise was noted. Contrast enhanced CT-scan showed rupture and hematoma of the right thyroid lobe; she underwent surgical exploration with hemi thyroidectomy and recovered uneventfully. Discussion Despite soft tissue injuries are relatively common after blunt neck trauma, isolated thyroid gland injury is extremely rare and is present in about 1–2% of the cases and in most of the cases there is an underlining pathology within the gland. Most patients arrived at the emergency room hemodynamically stable, presenting neck swelling, pain, respiratory distress, dysphagia and hoarseness. Diagnosis strategy should be focused to rule out respiratory or vascular compromise. Surgical exploration remains the most common treatment strategy. Conclusions Although the rarity of this condition, physicians should take in mind the possibility of thyroid injury after blunt neck trauma. Early detection and prompt treatment, can reduce life threatening complications. Management should be individualized to patient’s characteristics and surgeon’s experience. PMID:26001363

Leadership skills of senior residents, trauma fellows, and a nurse practitioner were assessed during simulation training for the initial management of blunt trauma. This was a pilot, observational study, that in addition to skill development and assessment also sought to determine the need for a dedicated leadership training course for surgical residents. The study evaluated the leadership skills and adherence to Advance Trauma Life Support (ATLS) guidelines of the team leaders during simulation training. The team leaders' performances on criteria regarding prearrival planning, critical actions based on ATLS, injury identification, patient management, and communication were evaluated for each of five blunt-trauma scenarios. Although there was a statistically significant increase in leadership skills for performing ATLS critical actions, P < 0.05, there were 10 adverse events. A structured simulation program dedicated to developing skills for team leadership willbe a worthwhile endeavor at our institution.

We report four cases of occult pneumothorax in patients who had suffered blunt trauma. In each case supine chest X-rays failed to diagnose an anterior pneumothorax. Subsequent spiral computerised tomography scans of the chest showed anterior pneumothoraces in all cases. In two of the cases anterior pneumothoraces were present in spite of a chest drain having been placed in the pleural cavity. We recommend the insertion of anteriorly positioned chest drains to relieve pneumothoraces in severely injured trauma patients.

Abdominal trauma is responsible for most genitourinary injuries. The incidence of renal artery injury and intrathoracic kidney is quite low in patients who present with blunt trauma experiencing damage. There are four defined etiologies for intrathoracic kidney, which include real intrathoracic ectopic kidney, eventration of the diaphragm, congenital diaphragmatic herniation, and traumatic diaphragmatic rupture. The traumatic intrathoracic kidney is an extremely rare case. We presented intrathoracic kidney case after traumatic posterior diaphragmatic rupture. PMID:26881170

The blunt trauma performance of fabric systems against 9 mm bullets is reported. Three shots were fired at each fabric system with impact velocity of 367±9 m/s and the depth of indentation on the modeling clay backing was measured. The results showed that 18-layer and 21-layer all-neat fabric systems failed the blunt trauma test. However, fabric systems with natural rubber (NR) latex coated fabric layers gave lower blunt trauma of between 25-32 mm indentation depths. Deformations on the neat fabrics upon impact were identified as broken yarns, yarn stretching and yarn pull-out. Deflections of the neat fabrics were more localised. For the NR latex coated fabric layers, no significant deformation can be observed except for peeled-off regions of the NR latex film at the back surface of the last layer. From the study, it can be said that the NR latex coated fabric layers were effective in reducing the blunt trauma of fabric systems.

A posttraumatic diaphragmatic hernia was diagnosed by ultrasound and x-ray examinations 1 year after a blunt trauma of the chest and abdomen. The diaphragmatic lesion could be seen retrospectively in the initial sonograms which were performed during the acute illness. It was however not possible to confirm the rupture during laparatomy.

Introduction Splenic pseudoaneurysms (SPA) are a rare but serious sequela of blunt traumatic injury to the spleen. Management of adult blunt splenic trauma is well-studied, however, in children, the management is much less well-defined. Presentation of case A 15 year-old male presented with severe abdominal pain of acute onset after sustaining injury to his left side while playing football. FAST was positive for free fluid in the abdomen. Initial abdomen CT demonstrated a grade III/IV left splenic laceration with moderate to large hemoperitoneum with no active extravasation or injury to the splenic vessels noted. A follow-up CT angiography of the abdomen demonstrated a splenic hypervascular structure suspicious for a small pseudoaneurysm. Splenic arteriogram which demonstrated multiple pseudoaneurysms arising from the second order splenic artery branches which was angioembolized and treated. Discussion & conclusion Questions still remain regarding the timing of repeat imaging for diagnosis of SPA following non-operative blunt splenic trauma, which patients should be imaged, and how to manage SPA upon diagnosis. More clinical study and basic science research is warranted to study the disease process of SPA in pediatric patient. We believe that our proposed management algorithm timely detect formation of delayed SPA formation and addresses the possible fatal disease course of pediatric SPA. PMID:26117449

Vehicle collisions represent more than 75% of mechanism of blunt abdominal trauma. In spite of the incomparable improvement of car safety devices, recent studies pointed out that the air bags might cause injuries, specially when it is not associated with seatbelt. In fact, some studies pointed out that crash victims using air bags alone have increased injury severity, hospitalisations, thoracoabdominal procedure, and rehabilitation. Some of the most frequently injured organs reported from air bag deployment are the liver (38%), the spleen (23%) and digestive system (17%). Injury of the hollow viscera are far less common. In particular, blunt abdominal trauma resulting in small bowel perforation is an infrequent lesion. These injuries are difficult to diagnose because specific signs are poor and a delay in treatment increases mortality and morbidity of the patients. We describe a case of thoracoabdominal trauma that occurred during a head-on collision after an air bag deployment without seatbelt use.

There have been several anthropological studies on trauma analysis in recent literature, but few studies have focused on the differences between the three mechanisms of trauma (sharp force trauma, blunt force trauma and ballistics trauma). The hypothesis of this study is that blunt force and ballistics fracture patterns in the skull can be differentiated using concentric fractures. Two-hundred and eleven injuries from skulls exhibiting concentric fractures were examined to determine if the mechanism of trauma could be determined by beveling direction. Fractures occurring in buttressed and non-buttressed regions were examined separately. Contingency tables and Pearson's Chi-Square were used to evaluate the relationship between the two variables (the mechanism of trauma and the direction of beveling), while Pearson's r correlation was used to determine the strength of the relationship. Contingency tables and Chi-square tests among the entire sample, the buttressed areas, and the non-buttressed areas led to the null hypothesis (no relationship) to be rejected. Pearson's r correlation indicated that the relationship between the variables studied is greater than chance allocation.

AIM: The aim of this retrospective study was to report the scapular fractures in patients with blunt chest trauma and to present the type and the frequency of associated thoracic injuries. MATERIAL AND METHODS: Nine patients with fractures of the scapula were included in the study. The mechanisms of the injury, the type of scapular fractures and associated thoracic injuries were analysed. RESULTS: Scapular fractures were caused by high-energy blunt chest trauma. The body of the scapula was fractured in all scapular fractures. In all cases, scapular fractures were associated with other thoracic injuries (average 3.25/per case). Rib fractures were present in eight patients, fractured clavicula - in four cases, the affection of pleural cavity - in eight of the patients and pulmonary contusion in all nine cases. Eight patients were discharged from the hospital up to the 15th day. One patient had died on the 3rd day because of postconcussional lung oedema. CONCLUSIONS: The study confirms the role of scapular fractures as a marker for the severity of the chest trauma (based on the number of associated thoracic injuries), but doesn’t present scapular fractures as an indicator for high mortality in blunt chest trauma patients.

Negli ultimi 20 anni il trattamento del trauma epatico chiuso si è modificato radicalmente passando da una gestione quasi costantemente chirurgica ad una non operativa in tutti i casi in cui non vi siano le condizioni di instabilità emodinamica o di variazione nella clinica del paziente traumatizzato. A tutt’oggi però non è raro osservare un approccio a tale condizione clinica seguendo criteri che la Medicina Basata sull’Evidenza dimostra essere superati. Presentiamo in questo lavoro il caso clinico di una donna di 34 anni che subiva un trauma diretto della regione postero-laterale dell’emitorace destro cadendo accidentalmente da una scala. Nonostante la gravità della lesione evidenziata dalla TC (IV grado secondo AAST Liver Injury Scale), si è optato per un trattamento non operativo data la condizione di stabilità emodinamica ottenuta con un primo bolo di cristalloidi. Una complicanza di tipo respiratorio ha complicato il quadro in terza giornata dal trauma richiedendo una toracentesi e dei cicli di ventilazione non invasiva. A 4 anni di distanza dal trauma la paziente sta bene e non lamenta disturbi. La letteratura mostra che il trattamento conservativo viene impiegato oggi in oltre l’85% dei traumi epatici, indipendentemente dall’entità della lesione. Il successo del trattamento conservativo varia nelle diverse casistiche dall’82% al 100% dei casi, e le sue complicanze, quando si verificano (14% dei traumi maggiori) possono spesso essere trattate con procedure di radiologia interventistica, evitando ancora l’intervento chirurgico. Oggi, in assenza di altre lesioni addominali che richiedano l’esplorazione chirurgica, l’indicazione al trattamento operativo è solo l’instabilità emodinamica del paziente che persiste o si ripresenta subito dopo un corretto trattamento rianimatorio iniziale.

We report the successful conservative management of an unusual case of esophageal perforation associated with an upper thoracic spinal fracture from blunt trauma in Minamata, Kumamoto, Japan. A 69-year-old man became paraplegic secondary to an L1 burst fracture caused by a boating accident and underwent posterior fixation on the day of admission. The patient also had a minimally displaced T4 vertebral fracture. Fever, dyspnea and elevated inflammatory markers all persisted postoperatively. Computed tomography showed free mediastinal air at the T4 level, and an esophagram showed contrast medium leakage, which helped diagnose esophageal perforation. The esophageal perforation healed with conservative treatment without life-threatening complications. The possibility of esophageal injury should always be considered when treating upper thoracic spinal injuries due to blunt trauma. PMID:28053736

Summary Background Blunt abdominal trauma is routinely encountered in the Emergency Department. It is one of the main causes of morbidity and mortality amongst the population below the age of 35 years worldwide. Renal artery injury secondary to blunt abdominal trauma however, is a rare occurrence. Here, we present two such cases, encountered in the emergency department sustaining polytrauma following motor vehicle accidents. Case Report We hereby report two interesting cases of renal artery injury sustained in polytrauma patients. In these two cases we revealed almost the entire spectrum of findings that one would expect in renal arterial injuries. Conclusions Traumatic renal artery occlusion is a rare occurrence with devastating consequences if missed on imaging. Emergency radiologists need to be aware of the CT findings so as to accurately identify renal artery injury. This case report stresses the need for immediate CT assessment of polytrauma patients with suspected renal injury, leading to timely diagnosis and urgent surgical or endovascular intervention.

Vessel-whale collision events represented the ultimate cause of death for 21 (52.5%) of the 40 North Atlantic right whales (Eubalaena glacialis) necropsied between 1970 and December 2006. Injuries seen in vessel-struck whales fall into two distinct categories: 1) sharp trauma, often resulting from contact with the propeller, and 2) blunt trauma, presumably resulting from contact with a vessel's hull. This study analyzes four trauma cases that resulted from vessel-whale collisions, which together provide a framework for a more critical understanding of lethal blunt and sharp trauma resulting from vessel collisions with right whales. In case no. 1, contact with a propeller resulted in three deep lacerations. The animal survived acute trauma only to succumb nearly 14 years later when the lesions reopened and became infected. In case no. 2, anecdotal reports linked the laceration of large arteries of the peduncle and histologic evidence of perimortem trauma at a bone fracture site to vessel-whale collision trauma. Case no. 3 had a laceration of the oral rete and a fracture of the rostrum. Both of the areas displayed histologic evidence of perimortem blunt trauma. Finally, in case no. 4, an antemortem mandibular fracture, two additional skull fractures, and widespread hemorrhage were consistent with severe blunt trauma. Evidence from each case, including the timing of trauma relative to the time of death and identifying characteristics of both trauma types, are presented. Before this study, no detailed comparative analysis of trauma pathology that resulted from lethal interactions between vessels and right whales had been conducted. This study demonstrates the importance of detailed gross and histologic examination in determining the significance and timing of traumatic events. This work represents a new paradigm for the differential diagnosis of lethal sharp and blunt trauma in right whales hit by ships and will enhance the present understanding of the impact of

Although potato cannons are an area of great interest among internet users, they are almost completely unknown in the medical community. These simple ballistic devices are made from plastic plumbing pipes and are powered with propellant gas from aerosol cans. By combustion of the gas-oxygen mixture, a high pressure is produced which propels the potato chunks through the barrel. It is the aim of this study to investigate the hazardous potential of these shooting devices. Test shots were performed using three illegally manufactured potato cannons that were confiscated by police authorities. Velocity, impulse, kinetic energy, and energy density were calculated. The risk of head and chest injuries was investigated by using Sturdivan's Blunt Criterion (BC), an energy based five parametric trauma model assessing the vulnerability to blunt weapons, projectile impacts, and behind-body-armor exposures. The probability of lethality due to blunt impact trauma to the chest was assessed using Sturdivan's lethality model. For potential head impacts, all test shots far exceeded the critical BC (head) value which corresponds to a 50% risk of skull fracture. The risk of injury with regard to chest impacts was similar. All but two test shots far exceeded the critical BC (chest) value corresponding to a 50% risk of sustaining a thoracic skeletal injury of Abbreviated Injury Scale 2 or 3. The probability of a lethal injury due to blunt chest impact was as high as 20%. To conclude, this work demonstrates that potato cannons should be considered dangerous weapons rather than as toys used by adventurous adolescents.

Introduction: Focused assessment with sonography for trauma (FAST) is a highly effective first screening tool for initial classification of abdominal trauma patients. The present study was designed to evaluate the outcome of patients with blunt abdominal trauma and positive FAST findings. Methods: The present prospective cross-sectional study was done on patients over 7 years old with normal abdominal examination, positive FAST findings, and available abdominopelvic computed tomography (CT) scan findings. The frequency of need for laparotomy as well as its probable risk factors were calculated. Results: 180 patients were enrolled (mean age: 28.0 ± 11.5 years; 76.7% male). FAST findings were confirmed by abdominopelvic CT scan in only 124 (68.9%) cases. Finally, 12 (6.6%) patients needed laparotomy. Mean age of those in need of laparotomy was significantly higher than others (36.75 ± 11.37 versus 27.34 ± 11.37, p = 0.006). Higher grading of spleen (p = 0.001) and hepatic (p = 0.038) ruptures increased the probability of need for laparotomy. Conclusion: 68.9% of the positive FAST findings in patients with blunt abdominal trauma and stable hemodynamics was confirmed by abdominopelvic CT scan and only 6.6% needed laparotomy. Simultaneous presence of free fluid and air in the abdominal area, old age, and higher grading o solid organ injuries were factors that had a significant correlation with need for laparotomy.

Non-penetrating chest trauma commonly causes a wide variety of cardiac injuries. Disruption of the aortic valve with resultant aortic regurgitation is not uncommon; conversely, a sinus of Valsalva-right atrial fistula, in the absence of a congenital sinus of Valsalva aneurysm, has been reported only once previously. This report describes the detection by preoperative cardiac catheterisation of both aortic regurgitation, and a sinus of Valsalva-right atrial fistula after blunt chest trauma, and its surgical management. The need for preoperative cardiac catheterisation in patients suffering from non-penetrating cardiac trauma is emphasised, even when the diagnosis appears cleas, because of the diverse nature and possible multiplicity of cardiac lesions.

Objectives To determine what proportion of abdominal computed tomography (CT) scans ordered after blunt trauma are positive and the applicability and accuracy of existing clinical prediction rules for obtaining a CT scan of the abdomen in this setting. Setting A leading trauma hospital, affiliated with the University of Ottawa. Design A retrospective cohort study. Patients and methods All patients with blunt trauma admitted to hospital over a 1-year period having an Injury Severity Score (ISS) greater than 12 who underwent CT of the abdomen during the initial assessment. Recorded data included age, sex, Glasgow Coma Scale (GCS) score, ISS, type of injuries, number of abdominal CT scans ordered, and scan results. Two clinical prediction rules were found in the literature that identify patients likely to have intra-abdominal injuries. These rules were applied retrospectively to the cohort. The predicted proportion of positive CT scans was compared with the observed proportion, and the sensitivity, specificity, and accuracy were estimated. Results Of the 297 patients entered in the study, 109 underwent abdominal CT. The median age was 32 years, 71% were male and the median ISS was 24. In only 36.7% (40 of 109) of scans were findings suggestive of intra-abdominal injuries. Application of one of the clinical prediction rules gave a sensitivity of 93.8% and specificity of 25.5% but excluded 23% of patients because of a GCS score less than 11. The second prediction rule tested could be applied to all patients and was highly sensitive (92.5%) and specific (100.0%). Conclusions The assessment of the abdomen in blunt trauma remains a challenge. Accuracy in predicting positive scans in equivocal cases is poor. Retrospective application of an existing clinical prediction rule was found to be highly accurate in identifying patients with positive CT findings. Prospective use of such a rule could reduce the number of CT scans ordered without missing significant injuries. PMID

A number of armed assaults on public officials occurred in the early 1970s, which prompted the Lightweight Soft Body Armor Program to develop modern, concealable, soft body armor. Methodology needed to be developed to (1) determine the effectiveness of the soft body armor to stop bullet penetration and (2) assess the potential injury from nonpenetrating blunt impacts to the body. Extensive research was performed under the program to develop methodologies to assess soft body armor, including behind-armor blunt trauma (BABT) evaluation. This methodology is still used today, and it has been applied extensively beyond the original intent. However, the origin of this methodology is not well understood by many researchers in the various fields in which it is being applied because the original documentation is difficult to obtain. Therefore, the purpose of this article is to provide a comprehensive review of the BABT to offer researchers information about its history and limitations.

The MRI-based computational model, previously validated by tagged MRI and HARP imaging analysis technique on in vivo human brain deformation, is employed to study transient wave dynamics during blunt head trauma. Three different constitutive models are used for the cerebrospinal fluid (CSF): incompressible solid elastic, viscoelastic and fluid-like elastic using an equation of state model. Three impact cases are simulated which indicate that the blunt impacts give rise not only to a fast pressure wave but also to a slow, and potentially much more damaging, shear (distortional) wave that converges spherically towards the brain center. The wave amplification due to spherical geometry is balanced by damping due to tissues' viscoelasticity and the heterogeneous brain structure, suggesting a stochastic competition of these two opposite effects. It is observed that this convergent shear wave is dependent on the constitutive property of the CSF whereas the peak pressure is not as significantly affected.
Introduction Computed tomography is commonly used to exclude occult injuries in patients with trauma, but imaging can reveal findings that are of uncertain etiology or clinical significance. We present a case of unsuspected pancreatic abnormality in a female patient with trauma who sustained an isolated blunt head injury. Case presentation A 25-year-old female Caucasian patient sustained massive blunt and penetrating head trauma, secondary to a large object penetrating through the vehicle windshield. Based on the mechanism of injury and clinical evaluation, it was felt to be an isolated head injury. However, computed tomography of her abdomen revealed an occult, intra-abdominal finding of significant pancreatic enlargement and peripancreatic fluid. There was no computed tomography evidence of parenchymal pancreatic laceration. The appearance of her pancreas on computed tomography was identical to that of acute pancreatitis or low-grade pancreatic injury, but her clinical history and laboratory values were not consistent with this, hence the term ‘pseudopancreatitis’. Later surgery for organ donation confirmed diffuse pancreatic and peripancreatic edema, but no hematoma, contusion or other evidence for direct traumatic injury. This was an isolated intra-abdominal abnormality. Conclusion The routine use of computed tomography in patients who have sustained trauma has led to increasing detection of unexpected findings. Clinical information such as mechanism of injury and blood work, along with careful evaluation of ancillary imaging findings (or lack of), is important for the provision of an appropriate differential diagnosis. We discuss the possible mechanism and differential diagnosis of an isolated pancreatic abnormality in the setting of non-abdominal trauma, which includes shock pancreas, overhydration, traumatic pancreatic injury and pancreatitis secondary to other etiologies.

To investigate the importance of route of nutrient administration on septic complications after blunt and penetrating trauma, 98 patients with an abdominal trauma index of at least 15 were randomized to either enteral or parenteral feeding within 24 hours of injury. Septic morbidity was defined as pneumonia, intra-abdominal abscess, empyema, line sepsis, or fasciitis with wound dehiscence. Patients were fed formulas with almost identical amounts of fat, carbohydrate, and protein. Two patients died early in the study. The enteral group sustained significantly fewer pneumonias (11.8% versus total parenteral nutrition 31.%, p less than 0.02), intra-abdominal abscess (1.9% versus total parenteral nutrition 13.3%, p less than 0.04), and line sepsis (1.9% versus total parenteral nutrition 13.3%, p less than 0.04), and sustained significantly fewer infections per patient (p less than 0.03), as well as significantly fewer infections per infected patient (p less than 0.05). Although there were no differences in infection rates in patients with injury severity score less than 20 or abdominal trauma index less than or equal to 24, there were significantly fewer infections in patients with an injury severity score greater than 20 (p less than 0.002) and abdominal trauma index greater than 24 (p less than 0.005). Enteral feeding produced significantly fewer infections in the penetrating group (p less than 0.05) and barely missed the statistical significance in the blunt-injured patients (p = 0.08). In the subpopulation of patients requiring more than 20 units of blood, sustaining an abdominal trauma index greater than 40 or requiring reoperation within 72 hours, there were significantly fewer infections per patient (p = 0.03) and significantly fewer infections per infected patient (p less than 0.01). There is a significantly lower incidence of septic morbidity in patients fed enterally after blunt and penetrating trauma, with most of the significant changes occurring in the

We induced mild blunt and blast injuries in rats using a custom-built device and utilized in-house diffusion tensor imaging (DTI) software to reconstruct 3-D fiber tracts in brains before and after injury (1, 4, and 7 days). DTI measures such as fiber count, fiber length, and fractional anisotropy (FA) were selected to characterize axonal integrity. In-house image analysis software also showed changes in parameters including the area fraction (AF) and nearest neighbor distance (NND), which corresponded to variations in the microstructure of Hematoxylin and Eosin (H&E) brain sections. Both blunt and blast injuries produced lower fiber counts, but neither injury case significantly changed the fiber length. Compared to controls, blunt injury produced a lower FA, which may correspond to an early onset of diffuse axonal injury (DAI). However, blast injury generated a higher FA compared to controls. This increase in FA has been linked previously to various phenomena including edema, neuroplasticity, and even recovery. Subsequent image analysis revealed that both blunt and blast injuries produced a significantly higher AF and significantly lower NND, which correlated to voids formed by the reduced fluid retention within injured axons. In conclusion, DTI can detect subtle pathophysiological changes in axonal fiber structure after mild blunt and blast trauma. Our injury model and DTI method provide a practical basis for studying mild traumatic brain injury (mTBI) in a controllable manner and for tracking injury progression. Knowledge gained from our approach could lead to enhanced mTBI diagnoses, biofidelic constitutive brain models, and specialized pharmaceutical treatments.

Objective: To determine the presentation, anatomical distribution, diagnostic method, management and outcome of hollow viscus injury (HVI) from blunt abdominal trauma. Methods: This was a retrospective cross-ecnal study including patients with blunt abdominal trauma leading to HVI admitted at Rajendra Institute of Medical Sciences, Ranchi, over a period of 4.5 years (January 2009 to July 2014). Data were retrieved from patients’ medical records. Total 173 patients with HVI due to blunt abdominal trauma, who underwent laparotomy at our institute, were reviewed. Data regarding clinical presentation, anatomical distribution, management and outcome were recorded and analysed. Results: Out of 173 patients 87.1% were men and 12.9% were women. Mean age of patients was 29±14.02 years. The most common site of injury was ileum (46.2%) followed by jejunum (44.5%). There were 5 gastric perforations (2.9%), 2 (1.15%) duodenal, 2 (1.15%) colonic, 2 (1.15%) sigmoidal and 2 (1.15%) rectal injuries. One caecal injury was also recorded. Road traffic accident was the most common mechanism of injury (57.2%) followed by fall from height (36.4%) and assault (6.4%). Free gas under diaphragm on erect abdomen radiography was seen in 85.5% of cases while preoperative CT Abdomen was done in 11.6% of cases. Treatment consisted of simple closure of the perforation (66.5%), resection and anastomosis (11.0%) and stoma (22.5%). Major complication was anastamotic leak which was recorded in 6.4% cases and 15.6% patients developed burst abdomen. Average hospital stay was 13±6 days. Overall mortality rate was 12.7%. Conclusion: Although early recognition of intestinal injuries from blunt abdominal trauma may be difficult in all cases, it is very important due to its tremendous life threatening potential. Age of the patient, anatomical site and time of presentation are probably main prognostic factors. PMID:27162889

Abstract We aimed to compare the diagnostic performance and inter-observer consistency between low dose chest CT (LDCT) and standard dose chest CT (SDCT) in the patients with blunt chest trauma. A total of 69 patients who met criteria indicative of blunt chest trauma (77% of male; age range, 16–85) were enrolled. All patients underwent LDCT without intravenous (IV) contrast and SDCT with IV contrast using parameters as following: LDCT, 40 mAs with automatic tube current modulation (ATCM) and 100 kVp (BMI <25, n = 51) or 120 kVp (BMI>25, n = 18); SDCT, 180 mAs with ATCM and 120 kVp. Transverse, coronal, sagittal images were reconstructed with 3-mm slice thickness without gap and provided for evaluation of 3 observers. Reference standard images (transverse, coronal, sagittal) were reconstructed using SDCT data with 1-mm slice thickness without gap. Reference standard was established by 2 experienced thoracic radiologists by consensus. Three observers independently evaluated each data set of LDCT and SDCT. Multiple-reader receiver operating characteristic analysis for comparing areas under the ROC curves demonstrated that there was no significant difference of diagnostic performance between LDCT and SDCT for the diagnosis of pulmonary injury, skeletal trauma, mediastinal injury, and chest wall injury (P > 0.05). The intraclass correlation coefficient was measured for inter-observer consistency and revealed that there was good inter-observer consistency in each examination of LDCT and SDCT for evaluation of blunt chest injury (0.8601–1.000). Aortic and upper abdominal injury could not be appropriately compared as LDCT was performed without using contrast materials and this was limitation of this study. The effective radiation dose of LDCT (average DLP = 1.52 mSv⋅mGy−1 cm−1) was significantly lower than those of SDCT (7.21 mSv mGy−1 cm−1). There is a great potential benefit to use of LDCT for initial evaluation of blunt chest trauma

Introduction Traumatic injury is a leading cause of death and disability in adults ≥ 65 years old, but there are few epidemiological studies addressing this issue. The aim of this study was to assess how characteristics of blunt traumatic injuries in adults ≥ 65 vary by age. Methods Using data from the a single-state trauma registry, this retrospective cohort study examined injured patients ≥ 65 admitted to all Level I and Level II trauma centers in Pennsylvania between 2011 and 2014 (n=38,562). Patients were stratified by age into three subgroups (age 65–74; 75–84; ≥85). We compared demographics, injury, and system-level across groups. Results We found significant increases in the proportion of female gender, (48.6% vs. 58.7% vs. 67.7%), white race (89.1% vs. 92.6% vs. 94.6%), and non-Hispanic ethnicity (97.5% vs. 98.6% vs. 99.4%) across advancing age across age groups, respectively. As age increased, the proportion of falls (69.9% vs. 82.1% vs. 90.3%), in-hospital mortality (4.6% vs. 6.2% vs. 6.8%), and proportion of patients arriving to the hospital via ambulance also increased (73.6% vs. 75.8% vs. 81.1%), while median injury severity plateaued (9.0% all groups) and the proportion of Level I trauma alerts (10.6% vs. 8.2% vs. 6.7%) decreased. We found no trend between age and patient transfer status. The five most common diagnoses were vertebral fracture, rib fracture, head contusion, open head wound, and intracranial hemorrhage, with vertebral fracture and head contusion increasing with age, and rib fracture decreasing with age. Conclusion In a large cohort of older adults with trauma (n= 38,000), we found, with advancing age, a decrease in trauma alert level, despite an increase in mortality and a decrease in demographic diversity. This descriptive study provides a framework for future research on the relationship between age and blunt traumatic injury in older adults. PMID:27833676

A Human Head Surrogate has been developed for use in behind helmet blunt trauma experiments. This human head surrogate fills the void between Post-Mortem Human Subject testing (with biofidelity but handling restrictions) and commercial ballistic head forms (with no biofidelity but ease of use). This unique human head surrogate is based on refreshed human craniums and surrogate materials representing human head soft tissues such as the skin, dura, and brain. A methodology for refreshing the craniums is developed and verified through material testing. A test methodology utilizing these unique human head surrogates is also developed and then demonstrated in a series of experiments in which non-perforating ballistic impact of combat helmets is performed with and without supplemental ceramic appliques for protecting against larger caliber threats. Sensors embedded in the human head surrogates allow for direct measurement of intracranial pressure, cranial strain, and head and helmet acceleration. Over seventy (70) fully instrumented experiments have been executed using this unique surrogate. Examples of the data collected are presented. Based on these series of tests, the Southwest Research Institute (SwRI) Human Head Surrogate has demonstrated great potential for providing insights in to injury mechanics resulting from non-perforating ballistic impact on combat helmets, and directly supports behind helmet blunt trauma studies.

The aim of this study was to assess radiomorphologic and clinical features of tracheal rupture due to blunt chest trauma. From 1992 until 1998 the radiomorphologic and clinical key findings of all consecutive tracheal ruptures were retrospectively analyzed. The study included ten patients (7 men and 3 women; mean age 35 years); all had pneumothoraces which were persistent despite suction drainage. Seven patients developed a pneumomediastinum as well as a subcutaneous emphysema on conventional chest X-rays. In five patients, one major hint leading to the diagnosis was a cervical emphysema, discovered on the lateral cervical spine view. Contrast-media-enhanced thoracic CT was obtained in all ten cases and showed additional injuries (atelectasis n = 5; lung contusion n = 4; lung laceration n = 2; hematothorax n = 2 and hematomediastinum n = 4). The definite diagnosis of tracheal rupture was made by bronchoscopy, which was obtained in all patients. Tracheal rupture due to blunt chest trauma occurs rarely. Key findings were all provided by conventional chest X-ray. Tracheal rupture is suspected in front of a pneumothorax, a pneumomediastinum, or a subcutaneous emphysema on lateral cervical spine and chest films. Routine thoracic CT could also demonstrate these findings but could not confirm the definite diagnosis of an tracheal rupture except in one case; in the other 9 cases this was done by bronchoscopy. Thus, bronchoscopy should be mandatory in all suspicious cases of tracheal rupture and remains the gold standard.

Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an electrophysiological disorder of a physically normal heart that occurs in children when the body is subjected to intense emotional or physical stress that causes adrenergic discharge. This troubling disease can be sporadic (spontaneous) or familial (genetic/inherited). Unfortunately, its associated ventricular tachycardia may cause sudden death, so early diagnosis of CPVT is very important. Treatment modalities include medical treatment, implantation of a cardioverter defibrillator, or surgical sympatectomy; but the implantable cardioverter defibrillator (ICD) should be the first choice in patients with a history of cardiac arrest. We herein present the case of a patient diagnosed with CPVT after a successful cardiopulmonary resuscitation triggered by blunt chest trauma. We implanted an implantable cardioverter defibrillator and started oral B-blocker treatment. During the course of follow-up, flecainide was added to his treatment depending on the patient’s status regarding recurrent ICD shock. The patient has now continued follow-up without recurrent ICD shock since flecainide treatment was initiated. In conclusion, in patients with syncope and sudden cardiac arrest secondary to physical stress or blunt chest trauma, CPVT should be considered and an implantable cardioverter defibrillator must be implanted. Additionally, flecainide theraphy should be considered to decrease recurrent ICD shock. PMID:27122894

Between June 1, 1976 and June 30, 1989 The Regional Trauma Unit at Sunnybrook Medical Centre in Toronto, Ontario, Canada received 3730 patients. Of these 335 (9%) sustained a liver injury, 95% being due to blunt trauma. Open peritoneal lavage was performed on 80% of liver trauma patients (267/335), 99% being true positive. A laparotomy was performed on 97% of patients (324/335). Major surgical treatment was required in 132 patients (41%) and minor treatment in 192 patients (59%). The remaining 11 patients were treated conservatively (n = 3) or died during resuscitation (n = 8). Morbidity directly related to the liver injury was seen in 29 of 249 surviving patients (11%) although overall morbidity was 27% (67/249). Reoperation was required in 6% (14/249) with abscess or hematoma accounting for 11 of 14 operations. The overall mortality rate was 26% (86/335). Eighty two percent of patients (n = 276) had a grade I, II or III liver trauma according to Moore’s classification with a mortality of 12% (n = 32). The remaining 18% of patients (n = 59) had a grade IV or V liver trauma with a mortality of 44% (n = 26). Of the 86 deaths, head injury accounted for 48 (56% of deaths); liver hemorrhage for 17 (20%), liver sepsis for (1%) and other causes for 20 deaths (23%). Thus death due to the liver injury itself (hemorrhage and sepsis) occurred in 18 out of 335 patients (5% overall). Head injury accounted for the death of 48 out of 335 patients (14% overall). Over the past 13 years a trend has occurred at our institution whereby we are seeing less liver trauma in our population of multiply injured patients from 12% (1976–1983) down to 7% (1985–1989); with a gradual decline in overall mortality from 32% (1976–1983) to 19% (1985–1989), whereas the precentage of deaths due to head injuries and liver injury have increased.

Context: Ibuprofen is widely used to manage pain and inflammation after orthopaedic trauma, but its effect on acute swelling has not been investigated. Cathodal high-voltage pulsed current (CHVPC) at 120 pulses per second and 90% of visible motor threshold is known to curb edema formation after blunt trauma to the hind limbs of rats. Objective: To examine the effects of ibuprofen, continuous CHVPC, and simultaneous ibuprofen and CHVPC on acute edema formation after blunt trauma to the hind limbs of rats. Design: Randomized, parallel-group, repeated-measures design. Setting: Laboratory animal facility. Participants: A total of 21 3-month-old Zucker Lean rats (mass = 288 ± 55 g) were studied. Intervention(s): We assessed the effects of ibuprofen, continuous CHVPC, and simultaneous ibuprofen and CHVPC on acute edema formation after blunt trauma to the hind limbs of rats. Main Outcome Measure(s): Limb volumes were measured immediately before and after trauma and every 30 minutes over the 4 hours of the experiment. Results: Volumes of treated limbs of all 3 experimental groups were smaller (P < .05) than those of untreated limbs, but no treatment was more effective than another. Conclusions: Ibuprofen, CHVPC, and simultaneous ibuprofen and CHVPC effectively curbed edema after blunt injury by roughly 50% relative to untreated but similarly injured control limbs of rats.

Blunt prenatal trauma is known to have consequences to the developing brain, and can result in subdural hematoma (SDH) or epidural hematoma (EDH). The authors present a case of blunt prenatal trauma resulting in a fetal SDH, intraparenchymal hematoma, and intraventricular hemorrhage, and perform a systematic review of the literature. This systematic review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Relevant studies (up to April 2016) that reported on cases of fetal SDH or EDH after blunt prenatal trauma were identified from the PubMed database. The primary outcome was fetal mortality, and the secondary outcome was neurological outcome. Fourteen studies were included in the analysis, comprising a total of 14 patients including the present case. The average gestational age at discovery of hemorrhage was 30.1 weeks. Nine mothers were in a motor vehicle collision and 3 were assaulted; the mechanism of injury for 2 mothers was not defined. Twelve patients had SDH, 1 had EDH, and 1 had conflicting reports. Three patients had intrauterine fetal demise, and 3 died in the neonatal period after birth. Three patients had persistent neurological deficit, and 5 were neurologically intact. Fetal SDH or EDH after blunt trauma to the mother trauma is rare and is associated with mortality. However, a significant number of patients can have good neurological outcomes.
Introduction The goal of non-operative management (NOM) for blunt splenic trauma (BST) is to preserve the spleen. The advantages of NOM for minor splenic trauma have been extensively reported, whereas its value for the more severe splenic injuries is still debated. The aim of this systematic review was to evaluate the available published evidence on NOM in patients with splenic trauma and to compare it with the operative management (OM) in terms of mortality, morbidity and duration of hospital stay. Methods For this systematic review we followed the "Preferred Reporting Items for Systematic Reviews and Meta-analyses" statement. A systematic search was performed on PubMed for studies published from January 2000 to December 2011, without language restrictions, which compared NOM vs. OM for splenic trauma injuries and which at least 10 patients with BST. Results We identified 21 non randomized studies: 1 Clinical Controlled Trial and 20 retrospective cohort studies analyzing a total of 16,940 patients with BST. NOM represents the gold standard treatment for minor splenic trauma and is associated with decreased mortality in severe splenic trauma (4.78% vs. 13.5% in NOM and OM, respectively), according to the literature. Of note, in BST treated operatively, concurrent injuries accounted for the higher mortality. In addition, it was not possible to determine post-treatment morbidity in major splenic trauma. The definition of hemodynamic stability varied greatly in the literature depending on the surgeon and the trauma team, representing a further bias. Moreover, data on the remaining analyzed outcomes (hospital stay, number of blood transfusions, abdominal abscesses, overwhelming post-splenectomy infection) were not reported in all included studies or were not comparable, precluding the possibility to perform a meaningful cumulative analysis and comparison. Conclusions NOM of BST, preserving the spleen, is the treatment of choice for the American Association for the

INTRODUCTION The spleen remains one of the most frequently injured organs following blunt abdominal trauma. In 2012, regional trauma networks were launched across England and Wales with the aim of improving outcomes following trauma. This retrospective cohort study investigated the management and outcomes of blunt splenic injuries before and after the establishment of regional trauma networks. METHODS A dataset was drawn from the Trauma Audit Research Network database of all splenic injuries admitted to English and Welsh hospitals from 1 April 2010 to 31 March 2014. Demographic data, injury severity, treatment modalities and outcomes were collected. Management and outcomes were compared before and after the launch of regional trauma networks. RESULTS There were 1457 blunt splenic injuries: 575 between 2010 and 2012 and 882 in 2012-14. Following the introduction of the regional trauma networks, use of splenic artery embolotherapy increased from 3.5% to 7.6% (P = 0.001) and splenectomy rates decreased from 20% to 14.85% (P = 0.012). Significantly more patients with polytrauma and blunt splenic injury were treated with splenic embolotherapy following 2012 (61.2% vs. 30%, P < 0.0001). Increasing age, injury severity score, polytrauma and Charlson Comorbidity Index above 10 were predictors of increased mortality (P < 0.001). Increasing systolic blood pressure (odds ratio, OR, 0.757, 95% confidence interval, CI, 0.716-0.8) and Glasgow Coma Scale (OR 0.988, 95% CI 0.982-0.995) were protective. CONCLUSIONS This study demonstrates a reduction in splenectomy rate and an increased use of splenic artery embolotherapy since the introduction of the regional trauma networks. This may have resulted from improved access to specialist services and reduced practice variation since the establishment of these networks.

A 39-year-old woman arrived at our emergency department, complaining of severe pain and swelling of her left leg. She had slipped down stairs and injured on her left leg about 3 months ago. Computed tomography angiography showed left distal superficial femoral artery’s pseudoaneurysm with arteriovenous fistula and thrombotic occlusion of left common iliac vein. We decided to do endovascular intervention due to severe venous hypertension and chronic inflammation around the fistula. The femoral arteriovenous fistula was closed via stent-graft (7 mm×5, 9 mm×5 cm) deployment. The occluded left iliac vein was reopened by nitinol metal stenting (12 mm×4 cm, 14 mm×4 cm). The authors report a very rare case of femoral arteriovenous fistula combined with iliac vein thrombosis developed after a blunt trauma. PMID:28377911

In the last few decades, various researches focus on the transient pressure in the behind armor blunt trauma. This paper presented a investigation on the transient pressure in the ballistic gelatin behind a soft body armor subjected to the impacting from three ammunitions. Experimental results show that three peaks appear on the pressure-time curves without taking into account the ammunition type and the impact velocity. Furthermore, numerical models of the test were created to compare modelling results to the pressure from the pressure gauges buried in the gelatin block. The main features on the pressure-time cure were discussed to analyze the wave formation and propagation. With the verified model, the effect of the boundary was also investigated to explain the wave reflection which appeared after two peaks.

In some fatalities from intense blunt trauma, the victims' clothes show strikingly yellow discoloration being in topographic correspondence with lacerated skin and crush damage to the underlying fatty tissue. This phenomenon is especially pronounced in light-colored textiles such as underwear made of cotton and in the absence of concomitant blood-staining. The constellation of findings seems to indicate that the fabric has been soaked with liquid body fat deriving from the contused adipose tissue. To check this hypothesis, textiles suspected to be contaminated with fat were investigated in 6 relevant cases. GC-MS-analysis proved the presence of 11 fatty acids. The fatty acid composition was similar to that of human adipose tissue with a high proportion of oleic acid (18:1). In total, the morphological and chemical findings demonstrated that the yellow discoloration of the victims' clothes was caused by fat from traumatized adipose tissue.

Delayed rupture of post-traumatic pseudoaneurysms of the visceral arteries, especially the pancreaticoduodenal artery, is uncommon. Here, we describe a 55-year-old man hemorrhaging from a pseudoaneurysm of the inferior pancreaticoduodenal artery (IPDA). Computed tomography of the abdomen showed active bleeding in the IPDA and large amounts of hemoperitoneum and hemoretroperitoneum. Selective mesenteric angiography showed that the pseudoaneurysm arose from the IPDA, and treatment by angioembolization failed because the involved artery was too tortuous to fit with a catheter. Damage control surgery with surgical ligation and pad packing was successfully performed. The patient had an uncomplicated postoperative course and was discharged 19 days after the operation. To our knowledge, this is the first report of ruptured pseudoaneurysm of an IPDA after blunt abdominal trauma from Korea. PMID:22880189

Extracranial vertebral pseudoaneurysms that develop following blunt trauma to the cervical area may have a benign course; however, embolic or ischemic stroke and progressive pseudoaneurysm enlargement may occur. We review the presentation and endovascular management of pseudoaneurysms of the cervical vertebral artery (VA) due to blunt trauma in nine patients (eight male, mean age 27years). Pseudoaneurysms occurred in dominant vessels in seven patients and coexisted with segmental narrowing in six. We favored endovascular intervention during the acute phase only in cases with significant narrowing of a dominant VA, especially when anticoagulation was contraindicated. Four patients were treated during the acute stage (contraindication to anticoagulation, mass effect, severely injured dominant VA/impending stroke); five during the chronic phase (pseudoaneurysm growth, ischemic stroke on aspirin prophylaxis, patient preference). Reconstructive techniques were favored over deliberate endovascular occlusion when dominant vessels were involved. Arterial reconstruction was performed in eight of nine patients using a flow-diverter implant (5 patients), stent-assisted coiling (1), overlapping stent implant (1), or implantation of a balloon-expandable stent (1). Deliberate VA occlusion with coils was performed in one of nine patients due to suboptimal expansion of the stented artery after flow-diverter implant. No neurological complications occurred during follow-up. All cases treated by reconstructive techniques showed complete, persistent pseudoaneurysm occlusion and full arterial patency. Endovascular therapy of traumatic VA pseudoaneurysms using neurostents and flow-diverters resulted in occlusion of the pseudoaneurysms, preservation of the parent vessel, and no periprocedural or delayed clinical complications, supporting the feasibility and safety of the approach.

Introduction Cost and radiation risk have prompted intense examination of trauma patient imaging. A proposed decision instrument (DI) for the use of chest computed tomography (CT), (CCT) in blunt trauma patients includes thoracic spine (TS) tenderness, altered mental status (AMS) and distracting painful injury (DPI) as potential predictor variables. TS CT is a separate, costly study whose value is currently ill-defined. The objective of this study is to determine test characteristics of these predictor variables alone, and in combination, to derive a TS injury DI. Methods Prospective cohort study of blunt trauma patients age > 14 in a Level I Trauma Center who had either CCT or TS CT. Results Of 1,798 blunt trauma patients, 1,174 (65.3%) had CCT, and 46 (2.6%) had a TS CT at physician discretion. CCT identified 58 TS injuries in 1,220 patients (4.8%). For 1,032 patients without AMS, 18/35 had TS tenderness, for sensitivity of 51.4%, specificity 84.7%, positive (PPV) and negative predictive values (NPV) of 10.5% and 98.0%. Positive likelihood ratio (+LR) was 3.35, with negative (−LR) 0.57. Among the 58 TS injuries, 23 had AMS for sensitivity of 39.7%, with other test characteristics of 85.8%, 12.2%, 96.6%, with +LR 2.79 and −LR 0.70. Thirty-eight of 58 had DPI, for sensitivity 65.5%, with other test characteristics 65.7%, 8.7%, and 97.4%, with +LR 1.91 and −LR 0.52. Combining 3 predictor variables into a proposed DI found 56/58 injuries for test characteristics of 96.6% (95% CI 88.1–99.6%), 49.1% (46.1–52.0%), 8.6% (6.6–11.1%) and 99.7% (CI 98.7–100%), with +LR 1.90 (1.76–2.04) and −LR 0.07 (0.02–0.28). If validated, the DI would exclude 572/1,220 CCT patients from separate TS CT (46.9%, CI 44.1–49.7%), and 141/511 (27.6%, CI 23.8–31.7%) patients who actually had TS CT in our cohort. Medicare payment at our center for sagittal reconstructions of TS CT is $280 for professional plus technical charges ($3,312 per study). The DI, if validated

Blunt trauma to chest cause injury to various cardiac structures. Isolated rupture of aortic valve without aortic dissection is rare complication of blunt chest trauma and can be caused by a tear or avulsion of the valve. We report a case of a 35-year-old male who presented with severe aortic insufficiency due to rupture of a non-infected congenital bicuspid aortic valve following non-penetrating chest trauma. The diagnosis was suggested by echocardiography and was confirmed by intra-operative and histological findings. The patient was successfully treated with surgical valve replacement with uneventful postoperative course and recovery. We describe patho-physiology, clinical manifestations, management and the literature review of traumatic rupture of bicuspid aortic valve. PMID:28164016
Introduction Advanced Trauma Life Support (ATLS) protocols provide a common approach for trauma resuscitations. This was a quality review assessing compliance with ATLS protocols at a Level I trauma center; specifically whether the presence or absence of a trauma team leader (TTL) influenced adherence. Methods This retrospective study was conducted on adult major trauma patients with acute injuries over a one-year period in a Level I Canadian trauma center. Data were collected from the Alberta Trauma Registry, and adherence to ATLS protocols was determined by chart review. Results The study identified 508 patients with a mean Injury Severity Score of 24.5 (SD 10.7), mean age 39.7 (SD 17.6), 73.8% were male and 91.9% were involved in blunt trauma. The overall compliance rate was 81.8% for primary survey and 75% for secondary survey. The TTL group compared to non-TTL group was more likely to complete the primary survey (90.9% vs. 81.8%, p = 0.003), and the secondary survey (100% vs. 75%, p = 0.004). The TTL group was more likely than the non-TTL group to complete the following tasks: insertion of two large bore IVs (68.2% vs. 57.7%, p = 0.014), digital rectal exam (64.6% vs. 54.7%, p = 0.023), and head to toe exam (77% vs. 67.1%, p = 0.013). Mean times from emergency department arrival to diagnostic imaging were also significantly shorter in the TTL group compared to the non-TTL group, including times to pelvis xray (mean 68min vs. 107min, p = 0.007), CT chest (mean 133min vs. 172min, p = 0.005), and CT abdomen and pelvis (mean 136min vs. 173min, p = 0.013). Readmission rates were not significantly different between the TTL and non-TTL groups (3.5% vs. 4.5%, p = 0.642). Conclusions While many studies have demonstrated the effectiveness of trauma systems on outcomes, few have explored the direct influence of the TTL on ATLS compliance. This study demonstrated that TTL involvement during resuscitations was associated with improved

Cardiac contusion is usually caused by blunt chest trauma and, although it is potentially a life-threatening condition, the diagnosis of a myocardial contusion is difficult because of non-specific symptoms and the lack of an ideal test to detect myocardial damage. Cardiac enzymes, such as creatine kinase (CK), creatine kinase MB fraction (CK-MB), cardiac troponin I (cTn-I), and cardiac troponin T (cTn-T) were used in previous studies to demonstrate the blunt cardiac contusion (BCC). Each of these diagnostic tests alone is not effective for diagnosis of BCC. The aim of this study was to investigate the serum heart-type fatty acid binding protein (h-FABP), N-terminal pro-B-type natriuretic peptide (NT-proBNP), CK, CK-MB, and cTn-I levels as a marker of BCC in blunt chest trauma in rats. The eighteen Wistar albino rats were randomly allocated to two groups; group I (control) (n=8) and group II (blunt chest trauma) (n=10). Isolated BCC was induced by the method described by Raghavendran et al. (2005). All rats were observed in their cages and blood samples were collected after five hours of trauma for the analysis of serum h-FABP, NT-pro BNP, CK, CK-MB, and cTn-I levels. The mean serum NT-pro BNP was significantly different between group I and II (10.3 ± 2.10 ng/L versus 15.4 ± 3.68 ng/L, respectively; P=0.0001). NT-pro BNP level >13 ng/ml had a sensitivity of 87.5%, a specificity of 70%, a positive predictive value of 70%, and a negative predictive value of 87.5% for predicting blunt chest trauma (area under curve was 0.794 and P=0.037). There was no significant difference between two groups in serum h-FABP, CK, CK-MB and c Tn-I levels. A relation between NT-Pro BNP and BCC was shown in this study. Serum NT-proBNP levels significantly increased with BCC after 5 hours of the blunt chest trauma. The use of NT-proBNP as an adjunct to other diagnostic tests, such as troponins, electrocardiography (ECG), chest x-ray and echocardiogram may be beneficial for diagnosis of

Introduction: Reduction of nonessential angiogram and embolization for patients sustaining blunt abdominal and pelvic trauma would allow improved utilization and decreased morbidity related to nontherapeutic embolization. We hypothesized that the nature of intravenous contrast extravasation (IVCE) on computed tomography (CT) would be directly related to the finding of extravasation on angiogram and need for embolization. Methods: A 5-year retrospective evaluation of trauma patients with IVCE on CT. Demographics, hemodynamics, and IVCE location and maximal dimension/volume were examined for relationship to IVCE on angiography and need for embolization. Primary complications were defined as nephropathy and acute respiratory distress syndrome. Results: A total of 128 patients were identified with IVCE on CT. Ninety-seven (75.8%) also had IVCE identified on angiography requiring some form of embolization. The size of IVCE on CT was not related to IVCE on angiogram (P = 0.69). Location of IVCE was related to need for embolization, with spleen embolization (85.4%) being much more frequent than liver (51.5%, P = 0.006). Complication rate was 8.7% in all patients, and was not different between patients undergoing embolization and those who did not (P = 0.40). Conclusion: IVCE volume was not predictive of continued bleeding and need for embolization. However, splenic injuries with IVCE required embolization more frequently. In contrast, liver injuries were found to have infrequent on-going IVCE on angiography. Complications associated with angiogram with or without embolization are infrequent, and CT findings may not be predictive of ongoing bleeding. We do not recommend selective exclusion of patients from angiographic evaluation when a blush is present.

Summary Background Diaphragmatic injuries occur in 0.8–8% of patients with blunt trauma. The clinical diagnosis of diaphragmatic rupture is difficult and may be overshadowed by associated injuries. Diaphragmatic rupture does not resolve spontaneously and may cause life-threatening complications. The aim of this study was to present radiological findings in patients with diaphragmatic injury. Material/Methods The analysis of computed tomography examinations performed between 2007 and 2012 revealed 200 patients after blunt thoraco-abdominal trauma. Diaphragmatic rupture was diagnosed in 13 patients. Twelve of these patients had suffered traumatic injuries and underwent a surgical procedure that confirmed the rupture of the diaphragm. Most of diaphragmatic ruptures were left-sided (10) while only 2 of them were right-sided. In addition to those 12 patients there, another patient was admitted to the emergency department with left-sided abdominal and chest pain. That patient had undergone a blunt thoracoabdominal trauma 5 years earlier and complained of recurring pain. During surgery there was only partial relaxation of the diaphragm, without rupture. The most important signs of the diaphragmatic rupture in computed tomography include: segmental discontinuity of the diaphragm with herniation through the rupture, dependent viscera sign, collar sign and other signs (sinus cut-off sign, hump sign, band sign). Results In our study blunt diaphragmatic rupture occurred in 6% of cases as confirmed intraoperatively. In all patients, coronal and sagittal reformatted images showed herniation through the diaphragmatic rupture. In left-sided ruptures, herniation was accompanied by segmental discontinuity of the diaphragm and collar sign. In right-sided ruptures, predominance of hump sign and band sign was observed. Other signs were less common. Conclusions The knowledge of the CT findings suggesting diaphragmatic rupture improves the detection of injuries in thoraco

Blunt thoraco-abdominal trauma in collision injuries in road traffic accident (RTA) occasionally results in diaphragmatic injury and rupture besides other serious multisystem injuries. These diaphragmatic injuries (DI) frequently go undetected specially when occur on the right side. DI associated with hemothorax need insertion of intercostal tube drainage (ICTD). ICTD has never been reported to precipitate diaphragmatic rupture and hernia. We are reporting such a rare case for the first time in medical literature. PMID:26933316

Objectives To examine the accuracy of standard trauma-room chest x-ray films in assessing blunt abdominal trauma and to determine the significance of missed injuries under these circumstances. Design A retrospective review. Setting A regional trauma unit in a tertiary-care institution. Patients Multiply injured trauma patients admitted between January 1988 and December 1990 who died within 24 hours of injury and in whom an autopsy was done. Intervention Standard radiography of the chest. Main Outcome Measures Chest injuries diagnosed and recorded by the trauma room team from standard anteroposterior x-ray films compared with the findings at autopsy and with review of the films by a staff radiologist initially having no knowledge of the injuries and later, if injuries remained undetected, having knowledge of the autopsy findings. Results Thirty-seven patients met the study criteria, and their cases were reviewed. In 11 cases, significant injuries were noted at autopsy and not by the trauma-room team, and in 7 cases these injuries were also missed by the reviewing radiologist. Injuries missed by the team were: multiple rib fractures (11 cases), sternal fractures (3 cases), diaphragmatic tear (2 cases) and intimal aortic tear (1 case). In five cases, chest tubes were not inserted despite the presence (undiagnosed) of multiple rib fractures and need for intubation and positive-pressure ventilation. Conclusions Significant blunt abdominal trauma, potentially requiring operative management or chest-tube insertion, may be missed on the initial anteroposterior chest x-ray film. Caution must therefore be exercised in interpreting these films in the trauma resuscitation room. PMID:8599789

This study evaluates the efficacy of arterial embolization (AE) for blunt hepatic traumas (BHT) as part of a combined management strategy based on the hemodynamic status of patients and CT findings. From 2000 to 2005, 84 patients were admitted to our hospital for BHT. Of these, 14 patients who had high-grade injuries (grade III [n = 2], grade IV [n = 9], grade V [n = 3]) underwent AE because of arterial bleeding and were included in the study. They were classified into three groups according to their hemodynamic status: (1) unresponsive shock, (2) shock improved with resuscitation, and (3) hemodynamic stability. Four patients (group 1) underwent, first, laparotomy with packing and, then, AE for persistent bleeding. Ten patients who were hemodynamically stable (group 1) or even unstable (group 2) underwent AE first, based on CT findings. AE was successful in all cases. The mortality rate was 7% (1/14). Only two angiography-related complications (gallbladder infarction) were reported. Liver-related complications (abdominal compartment syndrome and biliary complications) were frequent and often required secondary interventions. Our multidisciplinary approach for the management of BHT gives a main role to embolization, even for hemodynamically unstable patients. In this strategy AE is very efficient and has a low complication rate.

Euthanasia of small numbers of birds in case of injury or other illness directly on the farm may be necessary for welfare reasons. This should be done without transportation of the moribund animals in order to minimize pain and distress. Blood loss has to be avoided to minimize the risk of contaminating the environment. Cervical dislocation in combination with a blunt trauma may be an appropriate way to achieve this aim but the bird's age and body weight may influence the practicability of this method in the field. In this study, we evaluated broilers, broiler breeders, and turkeys of different age groups and weights up to nearly 16 kg for the efficacy of blunt trauma to induce unconsciousness, allowing subsequent killing of the bird without pain. The effect of blunt trauma on the brain was determined by electroencephalography (EEG). Auditory evoked potentials (AEPs) were recorded for each animal. Convulsions or tonic seizures were observed in all investigated animals after blunt trauma, including strong wing movements, torticollis, and stretching of legs. The EEG results demonstrate that the blunt trauma induced by a single, sufficiently strong hit placed in the frontoparietal region of the head led to a reduction or loss of the AEP in all groups of birds. These results clearly indicate a loss of sensibility and induction of unconsciousness, which would allow painless killing of the birds immediately after the induction of the blunt trauma.

The lesions of the skull following perforating traumas can create complex fractures. The blunt traumas can, according to the swiftness and the shape of the object used, create a depressed fracture. The authors describe through two clinical cases the lesional characteristic of the blunt traumas, perforating the skull using a hammer. In both cases the cranial lesions were very typical: they were geometrical, square shaped, of the same size than the tool (head and tip of the hammer). On the outer table of the skull, the edges of the wounds were sharp and regular. On the inner table, the edges of the wounds were beveled and irregular. The bony penetration in the depressed fracture results from a rupture of the outer table of the bone under tension, in periphery, by the bend of the bone to the impact (outbending) and then, from the inner table with comminuted bony fragmentation. Breeding on the fractures of the size and the shape of the blunt objects used is inconstant and differs, that it is the objects of flat surface or wide in opposition to those of small surface area. Fractures morphologies depend on one hand on these extrinsic factors and on the other hand, of intrinsic factors (structure of the bone). To identify them, we had previously conducted experimental work on cranial bone samples. The bone was submitted to a device for three-point bending. This work had shown properties of thickness and stiffness of the various areas of the vault. Our cases are consistent with these results and illustrate the variability of bone lesions according to region and mode of use of blunt weapons. Many studies have identified criteria for identification of the weapons and the assistance of digital and biomechanical models will be an invaluable contribution with this aim in the future.
Background Blunt carotid and vertebral artery injury (BCVI) occur infrequently. The incidence of this type of injury is difficult to determine as many emergency room patients are neurologically asymptomatic. The statistics have not been reported in Brazil. The objectives of the current study were: To evaluate the accuracy of criteria used to recommend angiotomography in the diagnosis of cervical BCVI in 100 patients with blunt cervical trauma in the trauma services section of a Brazilian quaternary care hospital. Methods During a 30-month (2006-2008), all patients admitted to the emergency room of Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo with blunt cervical trauma and potential risk of cervical vessel injury, were subjected to cervical angiotomography to diagnose BCVI. The data analyzed are presented as mean ± standard deviation, and statistical analyses included Chi-square and Fisher's exact tests, and the Mann-Whitney test. Results During the study period 2467 blunt trauma patients were admitted. In 100 patients that met the criteria for inclusion in the study, angiotomography identified 23 with BCVI, including 17 males and six females. The mean patient age was 34.81 ± 14.84 years. Car crash (49%) and car-pedestrian accidents (24%) were the most frequent causes of injury. Ten patients had internal carotid artery injuries, two patients had common carotid artery injuries, and 11 patients had vertebral artery injuries. Seven patients presented with Degree I arterial injuries, 10 patients presented with Degree II artery injuries, four patients presented with Degree IV artery injuries, one patient presented with a Degree V artery injury, and one patient had a carotid fistula. Seven out of the 23 patients with BCVI (30.4%) presented with cervical vertebrae fractures, and 11 out of the 23 patients with BCVI (47.8%) presented with facial fractures (LeFort II and III). Conclusions Although there is no consensus regarding the criteria

Purpose Using the data delivered by the German Trauma Register DGU® from 2002 till 2013, the value of different therapies of blunt thoracic aortic injury (BTAI) in Germany was analyzed. Methods Prospectively collected data of patients suffering from BTAI were retrospectively analyzed with focus on the different treatment modalities for grade I–IV injuries. Results 821 patients suffering from BTAI were identified: 51.6% (424) grade I injury, 35.4% (291) grade II or III injury and 12.9% (106) grade IV injury (77.5% men [44.94 ± 20.6 years]). The main patterns of injury were high- speed accidents and falls (78.0% [n = 640], 21.8% [n = 171] respectively). Significant differences between grade I and grade II/III as well as IV injuries could be assessed for the incidence of cardiopulmonary resuscitation, a Glasgow Coma Scale score below 8 and a systolic blood pressure below 90 mmHg (p-value: <0.001). In the primary admission subgroup, 44.1% (197/447) of the patients received best medical treatment, 55.9% received surgical intervention (250/447): Thereof 37.2% (93/250) received open surgery and 62.8% (147/250) had been treated by endovascular means. Significantly lower 24-h- and in-hospital-mortality rates were encountered after endovascular treatment for all gradings of BTAI (p-value: <0.001). Yet this subgroup of patients showed the lowest incidence of further severe injuries and cardiac arrest. Conclusion Endovascular therapy became the treatment of choice for BTAI in Germany. Patients who have been treated by surgical means showed the highest survival rate, especially endovascular therapy showed a favorable low mortality rate. PMID:28346475

Positron emission tomography with [(18)F]-fluorodeoxyglucose provides functional and anatomic information by visualising the uptake of radiolabelled glucose in tumour and inflammatory cells. We report delayed diagnosis of necrosis of the gastric fundus after blunt abdominal trauma in a 73-year-old man. After a car accident with head-on collision, the patient was stabilised in our emergency room. His femur was treated by internal fixation, his ellbow was stabilised by a fixateur externe. During surgery his status deteriorated. The patient was in need of high dosage of inotrops during the following days. He had a biventricular pacemaker implanted because of ischemic myocardiopathy, and he suffered from renal insufficiency. Over the next days, his haemodynamics improved. A central venous line had to be removed because of ensuing septic fever. The patient complained of upper abdominal pain and nausea. A sonography and computer tomography without contrast medium were performed with negative result. Because of contamination of the central venous line with Staphylococcus epidermidis the pacemaker was evaluated for infection by transoesophageal echocardiography, again without any findings. Because of ongoing fever and positive inflammatory markers a positron emission tomography was indicated, as a contrast examination and a magnetic resonance examination were not feasible because of the renal insufficiency and the pacemaker, respectively. Prophylactic removal of the pacemaker would have been a substantial risk for the patient due to his underlying myocardiopathy. Positron emission tomography showed an increased tracer uptake in the gastric fundus, which turned out to be necrotic by endoscopy. A laparoscopic resection followed, and drainage of an abscess, which had evolved subsequently between stomach and spleen stopped the inflammatory process. This case report demonstrates that positron emission tomography may be an alternative to computer tomography with contrast medium

Aortic regurgitation resulting from blunt chest trauma has been reported only 95 times, to our knowledge. The noncoronary and right coronary cusps are the cardiac structures most often injured. Although the aortic leaflets can appear to be undamaged after nonpenetrating trauma, they can have pathologic abnormalities and insufficient function. Some cases of posttraumatic aortic regurgitation progress slowly. Aortic valve replacement is the optimal treatment. We present the case of a then-62-year-old man who has lived more than 5 years after blunt-trauma aortic regurgitation. His is the only case of long-term survival on medical therapy alone among the 96 cases summarized in this report. PMID:27777534

This article examines why Southeast Asian American adolescents and emerging adults in two urban settings prefer to use "blunts," or hollowed-out cigars filled with marijuana, over other methods of drug intake. Rationales for preferring blunts were both instrumental and social. Blunts allowed users to more easily share marijuana, the preferred drug…
Background High mobility group box 1 (HMGB1) is a late mediator of systemic inflammation. Extracellular HMGB1 play a central pathogenic role in critical illness. The purpose of the study was to investigate the association between plasma HMGB1 concentrations and the risk of poor outcomes in patients with severe blunt chest trauma. Methods The plasma concentrations of HMGB1 in patients with severe blunt chest trauma (AIS ≥ 3) were measured by a quantitative enzyme-linked immunosorbent assay at four time points during seven days after admission, and the dynamic release patterns were monitored. The biomarker levels were compared between patients with sepsis and non-sepsis, and between patients with multiple organ dysfunction syndrome (MODS) and non-MODS. The related factors of prognosis were analyzed by using multivariate logistic regression analysis. The short-form 36 was used to evaluate the quality of life of patients at 12 months after injury. Results Plasma HMGB1 levels were significantly higher both in sepsis and MODS group on post-trauma day 3, 5, and 7 compared with the non-sepsis and non-MODS groups, respectively. Multivariate analysis showed that HMGB1 levels and ISS were independent risk factors for sepsis and MODS in patients with severe blunt chest trauma. Conclusions Plasma HMGB1 levels were significantly elevated in patients with severe blunt chest trauma. HMGB1 levels were associated with the risk of poor outcome in patients with severe blunt chest trauma. Daily HMGB1 levels measurements is a potential useful tool in the early identification of post-trauma complications. Further studies are needed to determine whether HMGB1 intervention could prevent the development of sepsis and MODS in patients with severe blunt chest trauma. PMID:25085006
Introduction The benefits of transporting severely injured patients by helicopter remain controversial. This study aimed to analyze the impact on mortality of helicopter compared to ground transport directly from the scene to a University hospital trauma center. Methods The French Intensive Care Research for Severe Trauma cohort study enrolled 2,703 patients with severe blunt trauma requiring admission to University hospital intensive care units within 72 hours. Pre-hospital and hospital clinical data, including the mode of transport, (helicopter (HMICU) versus ground (GMICU), both with medical teams), were recorded. The analysis was restricted to patients admitted directly from the scene to a University hospital trauma center. The main endpoint was mortality until ICU discharge. Results Of the 1,958 patients analyzed, 74% were transported by GMICU, 26% by HMICU. Median injury severity score (ISS) was 26 (interquartile range (IQR) 19 to 34) for HMICU patients and 25 (IQR 18 to 34) for GMICU patients. Compared to GMICU, HMICU patients had a higher median time frame before hospital admission and were more intensively treated in the pre-hospital phase. Crude mortality until hospital discharge was the same regardless of pre-hospital mode of transport. After adjustment for initial status, the risk of death was significantly lower (odds ratio (OR): 0.68, 95% confidence interval (CI) 0.47 to 0.98, P = 0.035) for HMICU compared with GMICU. This result did not change after further adjustment for ISS and overall surgical procedures. Conclusions This study suggests a beneficial impact of helicopter transport on mortality in severe blunt trauma. Whether this association could be due to better management in the pre-hospital phase needs to be more thoroughly assessed. PMID:23131068

Reformatted CTs of the thoracic and lumbar spine (CT T/L) from CTs of the chest, abdomen, and pelvis (CT body) may be performed for screening the thoracolumbar spine in patients sustaining blunt trauma. The purpose of this study was to determine whether there was a difference in the rate of detection of spinal fractures on CTs of the body compared to the reformatted T/L spine. A secondary endpoint was to evaluate whether cases dictated by trainees improved fracture detection rate. We reviewed the records of 250 consecutive blunt trauma patients that received CTs of the chest, abdomen, and pelvis (CT body) with concurrent CT T/L reformats. Each report was reviewed to determine if there was a thoracolumbar fracture and whether a trainee had been involved in interpreting the CT body. If a fracture was identified on either report, then the number, type, and location of each fracture was documented. Sixty-nine fractures, from a total of 38 patients, were identified on either the CT of the body or the CT T/L. Sensitivity for CT body interpretations was 94 % (95 % CI: 86-98 %) compared to a 97 % (95 % CI: 89-100 %) sensitivity for the CT T/L (p > 0.5). Although the sensitivity was 97 % (95 % CI: 88-100 %) when a trainee was involved in interpreting the body CT, there was no statistically significant improvement. The results suggest that with careful scrutiny most spine fractures can be diagnosed on body CT images without the addition of spine reformats. The most commonly missed finding is an isolated non-displaced transverse process fracture, which does not require surgical intervention and does not alter clinical management. The results suggest that thin section reformats do not need to be routinely ordered in screening blunt trauma patients, unless a bony abnormality is identified on the thicker section body CT images.

Pseudoaneurysm and arteriovenous fistulae of the renal artery are rare complications of kidney trauma. They commonly result from open traumas and occur within days after the injury. Common symptoms include acute haematuria, pain, or hypertension. We report the case of a fifty-three-year-old man presenting with symptomatic complex chronic high flow kidney arteriovenous fistula with interposition of a pseudoaneurysmal pouch and arterial aneurysmal dilatation in a solitary left kidney 38 years after a blunt trauma. Those conditions were successfully treated by endovascular embolization followed by regular radiologic, biological, and clinical follow-up. To the best of our knowledge, few similar cases were reported more than 20 years after trauma. However, no case combining an arteriovenous fistula and a pseudoaneurysm revealing as late as 38 years after trauma was found. In addition, management of those conditions on a solitary kidney and outcomes has not been described. We believe that our case depicts the clinical presentation and management of this rare entity that should not be unrecognized due to its potential lethal implications. PMID:28386510

Pelvic hemorrhage has been implicated as the cause of death in 50% of patients who die following pelvic fractures. To establish correlates of morbidity and mortality from pelvic fractures due to blunt trauma, we reviewed 236 patients treated during 4 years. The average age of the 144 men and 92 women was 31.5 years, the average Injury Severity Score was 21.3, the average blood requirement was 5 units, and the average hospital stay was 16.8 days. One hundred fifty-two patients (64.4%) were injured in motor vehicle accidents, 33 (14%) had motor vehicle-pedestrian accidents, 16 (6.8%) had crush injuries, 12 (5.1%) each had either motorcycle accidents or falls, and 11 (4.6%) had miscellaneous accidents. Eighteen patients (7.6%) died, with seven (38.9%) deaths due to hemorrhage. Only one death was caused by pelvic hemorrhage. Other deaths were due to hemorrhage from other sites (6), head injury (5), sepsis or multiple-organ failure (4), pulmonary injury (1), and pulmonary embolus (1). None of the septic deaths was related to a pelvic hematoma. Multivariate multiple regression analysis showed that the severity of injury was correlated with indices of severity of pelvic fractures such as fracture site (p less than 0.0001), fracture displacement (p less than 0.005), pelvic stability (p less than 0.0001), and vector of injury (p less than 0.01). However death could not be predicted on the basis of these indices of severity (p greater than 0.28). Of the nine patients who underwent pelvic arteriography, three required embolization of actively bleeding pelvic vessels, but seven had intra-abdominal hemorrhage that required laparotomy, and eight developed a coagulopathy. Massive bleeding from pelvic fractures was uncommon, and the major threat of hemorrhage was from nonpelvic sites. Furthermore, although injury severity was correlated with the severity of the pelvic fracture, hospital outcome was determined by associated injuries and not by the pelvic fracture. PMID:2039283

The Adult Children of Alcoholics Trauma Inventory (ACATI) registers variations in the recalled experience of growing up with problem drinkers. The ACATI includes measures of the duration and severity of parental alcohol-use-related problems, the drinking parents' behavior when intoxicated and sober, physical, psychological, and sexual abuse, and environmental factors. The ACATI correlated well with the Family Tree Questionnaire and showed excellent 14-day test-retest reliability for most variables. The test-retest was carried out in 2009 at a counseling service for young adults from families with alcohol-use-related problems in Denmark (N = 49).

Introduction Delayed bile leak following blunt liver trauma is not common. Presentation of case We presented a case report and literature review of delayed bile leak in a young male patient who presented with grade IV blunt liver injury following a motor vehicle collision; he was a restrained driver who hit a fixed object. Physical examination was unremarkable except for revelaed tachycardia, right upper quadrant abdominal tenderness, and open left knee fracture. A diagnosis of grade IV multiple liver lacerations with large hemo-peritoneum was made and urgent exploratory laparotomy was performed. The patient developed a biloma collection post- operatively. He underwent endoscopic retrograde cholangiopancreatography (ERCP) and common bile duct stenting. His recovery was uneventful, and he was discharged home after 1 month. Discussion This is a rare case with no intra or extra hepatic biliary radicle injury seen on magnetic resonance cholangiopancreatography (MRCP) and no evidence of leak by ERCP. A review of the literature to highlight the incidence of delayed bile leak revealed only few reported cases. Conclusion Our findings demonstrate the need for prompt diagnosis and treatment of delayed bile leak in blunt liver injuries. When these principles are followed, a successful outcome is possible.

Necrotizing fasciitis (NF) is a rare bacterial infection with dramatic course, characterized by widespread necrosis of the skin, subcutaneous tissue, and superficial fascia which can often lead to death. We present a case of a 27-year-old male with NF. One day after experiencing blunt abdominal trauma caused by falling over bike handlebars, the patient was admitted to a regional hospital and treated for diffuse abdominal pain and large hematoma of the anterior abdominal wall. Due to worsening of general condition, he was referred to our hospital the following day and operated on urgently. Surgery revealed rupture of the coecum with peritonitis and abdominal wall infection. After surgery, fulminant necrotizing fasciitis developed. Antibiotics were prescribed according to wound cultures and subsequent necrectomies were performed. After 25 days, reconstruction of the abdominal wall with skin grafts was obtained. Despite all resuscitation measures including fluids, blood transfusions, and parenteral nutrition, lung infection and MODS caused death 42 days after initial operation. Blunt abdominal trauma can cause the rupture of intestine, and if early signs of peritoneal irritation should present, emergency laparotomy should be performed. Disastrous complication are rare but lethal.

A 12-year-old boy suffered a blunt chest trauma. Some hours later, a pulsatile bilateral jugular venous distension, a holosystolic murmur heard at the low parasternal border and hepatomegaly were observed. On echocardiography, ruptured chordae tendineae of the posterior leaflet of the tricuspid valve, as well as tricuspid regurgitation were detected. He remained asymptomatic during hospital stay and was discharged home in good condition. Thus, isolated ruptured chordae tendineae of the posterior leaflet of the tricuspid valve is another cause of tricuspid regurgitation following blunt chest trauma.

Abstract The aim of this study was to investigate and compare the injury characteristics, severity, and outcome between underweight and normal-weight patients hospitalized for the treatment of all kinds of trauma injury. This study was based on a level I trauma center Taiwan. The detailed data of 640 underweight adult trauma patients with a body mass index (BMI) of <18.5 kg/m2 and 6497 normal-weight adult patients (25 > BMI ≥ 18.5 kg/m2) were retrieved from the Trauma Registry System between January 1, 2009, and December 31, 2014. Pearson's chi-square test, Fisher's exact test, and independent Student's t-test were performed to compare the differences. Propensity score matching with logistic regression was used to evaluate the effect of underweight on mortality. Underweight patients presented a different bodily injury pattern and a significantly higher rate of admittance to the intensive care unit (ICU) than did normal-weight patients; however, no significant differences in the Glasgow Coma Scale (GCS) score, injury severity score (ISS), in-hospital mortality, and hospital length of stay were found between the two groups. However, further analysis of the patients stratified by two major injury mechanisms (motorcycle accident and fall injury) revealed that underweight patients had significantly lower GCS scores (13.8 ± 3.0 vs 14.5 ± 2.0, P = 0.020), but higher ISS (10.1 ± 6.9 vs 8.4 ± 5.9, P = 0.005), in-hospital mortality (odds ratio, 4.4; 95% confidence interval, 1.69–11.35; P = 0.006), and ICU admittance rate (24.1% vs 14.3%, P = 0.007) than normal-weight patients in the fall accident group, but not in the motorcycle accident group. However, after propensity score matching, logistic regression analysis of well-matched pairs of patients with either all trauma, motorcycle accident, or fall injury did not show a significant influence of underweight on mortality. Exploratory data analysis revealed that underweight patients

A 59-year-old man suffered blunt injury to the left chest during a fall in August 2004. He had 5 repeated episodes of back and left chest pain in three years since August 2005. Since these symptoms were accompanied by left pleural effusion and serum inflammatory reaction, the tentative diagnosis was pleuritis. Although examinations of pleural effusion showed exudation with marked augmentation of inflammatory cells, there were no findings that suggested the cause of repetitive pleuritis. All symptoms were relieved within one or two weeks following administration of non-steroid anti-inflammatory drugs. Surgical thoracoscopy was carried out to investigate the cause of repeated pleuritis, and an acquired deficit of the left pericardium was noted. We considered this case to be postcardiac injury syndrome causing repeated pleuritis following blunt chest injury.

This case report describes a right subclavian artery aneurysm secondary to long-term repetitive blunt trauma. A 62-year-old man with a right subclavian artery aneurysm had had a history of bird hunting using a shotgun that impacted substantially against his right clavicula and shoulder weekly for >20 years. The patient underwent open repair with partial sternotomy and distal balloon control. The aneurysmal sac was resected, and the right subclavian artery was reconstructed with a primary end-to-end anastomosis. Histopathologic examination of the resected aneurysmal wall revealed that all three layers of the arterial wall were comparatively intact, with fibrosis and lipid deposition in the intima and in various degrees of degeneration in the media, suggesting a true aneurysm.

Patients with a (potential) cervical spine injury can be subdivided into low-risk and high-risk patients. With a detailed history and physical examination the cervical spine of patients in the "low-risk" group can be "cleared" without further radiographic examinations. X-ray imaging (3-view series) is currently the primary choice of imaging for patients in the "low-risk" group with a suspected cervical spine injury after blunt trauma. For patients in the "high-risk"group because of its higher sensitivity a computed tomography scan is primarily advised or, alternatively, the cervical spine is immobilised until the patient can be reliably questioned and examined again. For the imaging of traumatic soft tissue injuries of the cervical spine magnetic resonance imaging is the technique of choice.

Blunt cerebrovascular injury (BCVI) to the carotid artery is a relatively rare injury that is difficult to identify even with imaging. Any symptoms or neurological deficits following blunt neck injury mandate evaluation and consideration of BCVI. In an effort to highlight this issue, we report the case of a 31-year-old male patient who presented with left-sided weakness consistent with transient ischemic attack (TIA) and concussion. The patient's symptoms occurred within 24 hours of a blunt neck injury sustained by a knee strike during a basketball game. An initial computerized tomography (CT) scan of the brain was normal; a CT angiogram (CTA) of the neck and carotids did not reveal obstruction, dissection, stenosis, or abnormalities of the carotid or vertebral vessels and the patient was subsequently discharged. A magnetic resonance imaging (MRI) of the brain obtained four days after the initial injury demonstrated an acute infarct in the right middle cerebral artery (MCA) territory. Thus, despite initial negative imaging, neurological deficits must be aggressively pursued in order to prevent stroke in BCVI cases.

Cigarette smoking (CS) aggravates post-traumatic acute lung injury and increases ventilator-induced lung injury due to more severe tissue inflammation and apoptosis. Hyper-inflammation after chest trauma is due to the physical damage, the drop in alveolar PO2, and the consecutive hypoxemia and tissue hypoxia. Therefore, we tested the hypotheses that 1) CS exposure prior to blunt chest trauma causes more severe post-traumatic inflammation and thereby aggravates lung injury, and that 2) hyperoxia may attenuate this effect. Immediately after blast wave-induced blunt chest trauma, mice (n=32) with or without 3-4 weeks of CS exposure underwent 4 hours of pressure-controlled, thoraco-pulmonary compliance-titrated, lung-protective mechanical ventilation with air or 100 % O2. Hemodynamics, lung mechanics, gas exchange, and acid-base status were measured together with blood and tissue cytokine and chemokine concentrations, heme oxygenase-1 (HO-1), activated caspase-3, and hypoxia-inducible factor 1-α (HIF-1α) expression, nuclear factor-κB (NF-κB) activation, nitrotyrosine formation, purinergic receptor 2X4 (P2XR4) and 2X7 (P2XR7) expression, and histological scoring. CS exposure prior to chest trauma lead to higher pulmonary compliance and lower PaO2 and Horovitz-index, associated with increased tissue IL-18 and blood MCP-1 concentrations, a 2-4-fold higher inflammatory cell infiltration, and more pronounced alveolar membrane thickening. This effect coincided with increased activated caspase-3, nitrotyrosine, P2XR4, and P2XR7 expression, NF-κB activation, and reduced HIF-1α expression. Hyperoxia did not further affect lung mechanics, gas exchange, pulmonary and systemic cytokine and chemokine concentrations, or histological scoring, except for some patchy alveolar edema in CS exposed mice. However, hyperoxia attenuated tissue HIF-1α, nitrotyrosine, P2XR7, and P2XR4 expression, while it increased HO-1 formation in CS exposed mice. Overall, CS exposure aggravated post

DTPA clearance rate is a reliable index of alveolar epithelial permeability, and is a highly sensitive marker of pulmonary epithelial damage, even of mild degree. In this study, 99mTc-DTPA aerosol inhalation scintigraphy was used to assesss the pulmonary epithelial membrane permeability and to investigate the possible application of this permeability value as an indicator of early alveolar or interstitial changes in patients with blunt chest trauma. A total of 26 patients was chest trauma (4 female, 22 male, 31-80 yrs, mean age; 53+/-13 yrs) who were referred to the emergency department in our hospital participated in this tsudy. Technetium-99m diethylene triamine pentaacetic acid (DTPA) aerosol inhalation scintigraphy was performed on the first and thirtieth days after trauma. Clearance half times (T1/2) were calculated by placing a mono-exponential fit on the curves. Penetration index (PI) was calculated on the first-minute image. On the first day, mean T1/2 value of the whole lung was 63+/-19 minutes (min), and thirtieth day mean T1/2 value was 67+/-21 min. On the first day, mean PI values of the lung and 30th day mean PI value were 0.60+/-0.05, and 0.63+/-0.05, respectively. Significant changes were observed in radioaerosol clearance and penetration indices. Following chest trauma, clearance of 99mTc-DTPA increased owing to breakdown of the alveolar-capillary barrier. This increase in the epithelial permeability of the lung appears to be an early manifestation of lung disease that may lead to efficient therapy in the early phase.

Purpose. To determine the value of aortography in the assessment of occult aortic and great vessel injuries when routinely performed during screening angiography for blunt cerebrovascular injury (BCVI). Methods. One hundred and one consecutive patients who received both aortography and screening four-vessel angiography over 4 years were identified retrospectively. Angiograms for these patients were evaluated, and the incidence of occult mediastinal vascular injury was determined. Results. Of the 101 patients, 6 (6%) had angiographically documented traumatic aortic injuries. Of these 6 patients, one injury (17%) was unsuspected prior to angiography. Four of the 6 (67%) also had BCVI. One additional patient also had an injury to a branch of the subclavian artery. Conclusion. Routine aortography during screening angiography for BCVI is not warranted due to the low incidence (1%) of occult mediastinal arterial injury. However, in the setting of a BCVI screening study and no CT scan of the chest, aortography may be advantageous.

Profunda femoris artery (PFA) pseudoaneurysm after blunt trauma without associated femur fracture is a rare occurrence. Most of the reported cases of PFA pseudoaneurysm in the English literature developed after penetrating trauma, surgical procedures, and femur fractures. We present two such cases following blunt trauma and without any associated long bone injury. After initial imaging failed to show any long bone fracture, CT angiography confirmed pseudoaneurysm of the branch of the PFA. Both patients were then treated with emergent coil embolization of the bleeding vessel. Pseudoaneurysms typically present late and signs of persistent hip pain, thigh swelling, presence of a pulsatile mass, and even unexplained anemia all may suggest the diagnosis. Recognition of PFA pseudoaneurysm requires high index of suspicion and is often difficult to diagnose clinically because of its location. PMID:28246563
Background The BIG score (Admission base deficit (B), International normalized ratio (I), and Glasgow Coma Scale (G)) has been shown to predict mortality on admission in pediatric trauma patients. The objective of this study was to assess its performance in predicting mortality in an adult trauma population, and to compare it with the existing Trauma and Injury Severity Score (TRISS) and probability of survival (PS09) score. Materials and methods A retrospective analysis using data collected between 2005 and 2010 from seven trauma centers and registries in Europe and the United States of America was performed. We compared the BIG score with TRISS and PS09 scores in a population of blunt and penetrating trauma patients. We then assessed the discrimination ability of all scores via receiver operating characteristic (ROC) curves and compared the expected mortality rate (precision) of all scores with the observed mortality rate. Results In total, 12,206 datasets were retrieved to validate the BIG score. The mean ISS was 15 ± 11, and the mean 30-day mortality rate was 4.8%. With an AUROC of 0.892 (95% confidence interval (CI): 0.879 to 0.906), the BIG score performed well in an adult population. TRISS had an area under ROC (AUROC) of 0.922 (0.913 to 0.932) and the PS09 score of 0.825 (0.915 to 0.934). On a penetrating-trauma population, the BIG score had an AUROC result of 0.920 (0.898 to 0.942) compared with the PS09 score (AUROC of 0.921; 0.902 to 0.939) and TRISS (0.929; 0.912 to 0.947). Conclusions The BIG score is a good predictor of mortality in the adult trauma population. It performed well compared with TRISS and the PS09 score, although it has significantly less discriminative ability. In a penetrating-trauma population, the BIG score performed better than in a population with blunt trauma. The BIG score has the advantage of being available shortly after admission and may be used to predict clinical prognosis or as a research tool to risk stratify trauma

Background The management of pancreatic trauma is complex. The aim of this study was to report our experience in the management of pancreatic trauma. Methods All patients hospitalized between 2005 and 2013 for pancreatic trauma were included. Traumatic injuries of the pancreas were classified according to the American Association for Surgery of Trauma (AAST) in five grades. Mortality and morbidity were analyzed. Results A total of 30 patients were analyzed (mean age: 38±17 years). Nineteen (63%) patients had a blunt trauma and 12 (40%) had pancreatic injury ≥ grade 3. Fifteen patients underwent exploratory laparotomy and the other 15 patients had nonoperative management (NOM). Four (13%) patients had a partial pancreatectomy [distal pancreatectomy (n=3) and pancreaticoduodenectomy (n=1)]. Overall, in hospital mortality was 20% (n=6). Postoperative mortality was 27% (n=4/15). Mortality of NOM group was 13% (n=2/15) in both cases death was due to severe head injury. Among the patients who underwent NOM, three patients had injury ≥ grade 3, one patient had a stent placement in the pancreatic duct and two patients underwent endoscopic drainage of a pancreatic pseudocyst. Conclusions Operative management of pancreatic trauma leads to a higher mortality. This must not be necessarily related to the pancreas injury alone but also to the associated injuries including liver, spleen and vascular trauma which may cause impaired outcome more than pancreas injury.

Background. The trauma burden globally accounts for high levels of mortality and morbidity. Blunt abdominal trauma (BAT) contributes significantly to this burden. Patient's evaluation for BAT remains a diagnostic challenge for emergency physicians. SSORTT gives a score that can predict the need for laparotomy. The objective of this study was to assess the accuracy of SSORTT score in predicting the need for a therapeutic laparotomy after BAT. Method. A prospective observational study. Eligible patients were evaluated for shock and the presence of haemoperitoneum using a portable ultrasound machine. Further evaluation of patients following the standard of care (SOC) protocol was done. The accuracy of SSORTT score in predicting therapeutic laparotomy was compared to SOC. Results. In total, 195 patients were evaluated; M : F ratio was 6 : 1. The commonest injuries were to the head 80 (42%) and the abdomen 54 (28%). A SSORTT score of >2 appropriately identified patients that needed a therapeutic laparotomy (with sensitivity 90%, specificity 90%, PPV 53%, and NPV 98%). The overall mortality rate was 17%. Conclusion. Patients with a SSORTT score of 2 and above had a high likelihood of requiring a therapeutic laparotomy. SSORTT scoring should be adopted for routine practice in low technology settings.

Traumatic injury to the knee leads to the development of post-traumatic osteoarthritis. The objective of this study was to characterize the effects of a single intra-articular injection of a non-ionic surfactant, Poloxamer 188 (P188), in preservation of meniscal tissue following trauma through maintenance of meniscal glycosaminoglycan (GAG) content and mechanical properties. Flemish Giant rabbits were subjected to a closed knee joint, traumatic compressive impact with the joint constrained to prevent anterior tibial translation. The contralateral limb served as an un-impacted control. Six animals (treated) received an injection of P188 in phosphate buffered saline (PBS) post trauma, and another six animals (sham) received a single injection of PBS to the impacted limb. Histological analyses for GAG was determined 6 weeks post trauma, and functional outcomes were assessed using stress relaxation micro-indentation. The impacted limbs of the sham group demonstrated a significant decrease in meniscal GAG coverage compared to non-impacted limbs (p<0.05). GAG coverage of the impacted P188 treated limbs was not significantly different than contralateral non-impacted limbs in all regions except the medial anterior (p<0.05). No significant changes were documented in mechanics for either the sham or treated groups compared to their respective control limbs. This suggests that a single intra-articular injection of P188 shows promise in prevention of trauma induced GAG loss.

A 19-year-old male suffered orthopedic fractures, blunt solid organ injury and pneumopericardium after a fall from 40 feet. With the exception of an external fixation device, he was managed non-operatively and discharged to a rehabilitation unit after 8 days. He was readmitted 4 days later with chest pain and clinical evidence of pericardititis that resolved with the initiation of non-steroidal anti-inflammatory drugs and colchicine. He returned to the rehabilitation hospital, but was readmitted once again for chest pain and hypotension. Echocardiogram revealed cardiac tamponade that required emergent drainage. He tolerated the procedure well and was discharged home from the hospital to continue treatment for his pericarditis. He is doing well at 3 months of follow-up. PMID:25709254

Full medical evaluation is paramount for all trauma patients. Minor traumas are often overlooked, as they are thought to bear low injury potential. In this case report, we describe the case of a 48-year-old man presenting to our Emergency Department with mild to moderate right-sided shoulder and scapular pain following a fall from his own height ten days previously. Clinical and paraclinical investigations (CT) revealed diffuse right shoulder pain, with crepitations on palpation of the neck, right shoulder, and right lateral chest wall. Computed tomography (CT) demonstrated right-sided costal fractures (ribs 7 to 9), with diffuse subcutaneous emphysema and pneumomediastinum due to laceration of the visceral and parietal pleura and the adjacent lung parenchyma. In addition, a small ipsilateral pneumothorax was found. Surprisingly, the clinical status was only minimally affected by mild to moderate pain and minor functional impairment. PMID:28392950

Laryngeal fracture is a rare traumatic injury, potentially fatal, with an estimated incidence of 1 in 30,000 patients admitted to severe trauma centers. Because of the rarity of this injury, physician may be not aware of its existence, leading to a late diagnosis of this entity. We report a case of a 59-year-old woman admitted to the emergency room after a motorcycle accident with cervical trauma. The patient presented with dysphonia, hemoptysis, cervical subcutaneous emphysema, and increasing respiratory distress that led to the intubation of the patient. CT-scan demonstrated displaced fracture of the cricoid and thyroid cartilage. The patient was submitted to tracheostomy and the fracture was surgically repaired. Tracheostomy was removed in third postoperative month. The patient presented a good recovery, reporting only hoarseness but without swallowing or breathing problems at 6-month follow-up.

In pediatrics ultrasound has long been viewed more favorably than imaging that exposes patients to radiation and iodinated contrast or requires sedation. It is child-friendly and diagnostic capabilities have been improved with the advent of contrast-enhanced ultrasound (CEUS). The application of CEUS is indeed promising. However, no ultrasound contrast agent manufactured today is registered for pediatric use in Europe. The contrast agent SonoVue(®) has recently been approved by the FDA under the name of Lumason(®) to be used in hepatic investigations in adults and children. This article reviews the literature with respect to 2 specific applications of CEUS in children: 1) identification of parenchymal injuries following blunt abdominal trauma, and 2) classification of focal liver lesions. Applications were chosen through the CEUS guidelines published by the European Federation of Societies for Ultrasound in Medicine and Biology and World Federation for Ultrasound in Medicine and Biology. Literature was obtained by searching Medline and Pubmed Central (using Pubmed), Scopus database and Embase. CEUS proved to be an effective investigation in the hemodynamically stable child for identifying parenchymal injuries and for the characterization of focal liver lesions. CEUS showed comparable performance to CT and MRI with a specificity of 98% for identifying benign lesions and a negative predictive value of 100%. For the applications reviewed here, CEUS holds promising perspectives and can help reduce radiation exposure and use of iodinated contrast agents in pediatrics, thereby potentially reducing complications in routine imaging.

When requested to evaluate surviving victims of blunt head trauma the forensic expert has to draw mainly on medical documentation from the time of hospital admission. In many cases these consist of written clinical records, radiographs and in some cases photographic documentation of the injuries. We report two cases of survived severe blunt head trauma where CT images, which had primarily been obtained for clinical diagnostic purposes, were used for forensic assessment. 3D reconstructions of the clinical CT-images yielded valuable information regarding the sequence, number and direction of the impacts to the head, their gross morphology and the inflicting weapon. We conclude that computed tomography and related imaging methods, along with their 3D reconstruction capabilities, provide a useful tool to approach questions in clinical forensic casework.

INTRODUCTION Group AB plasma, the traditional universal donor plasma product, is a limited resource. We compared outcomes of Group A plasma transfusion in comparison to AB. METHODS Analysis of blunt-injured patients who received emergency release plasma from was performed. Multivariable logistic regression was utilized to identify associations with morbidity and mortality. RESULTS There were 191 patients; 115 Group A and 76 Group AB. No differences were seen in age, sex, plasma transfusions, uncrossmatched red blood cells (RBCs), and Glasgow Coma Scale (GCS). Patients who received Group A plasma had significantly lower Injury Severity Score, chest Abbreviated Injury Scale, and scene transfer rate but not head AIS, or abdomen AIS. In addition, significant differences were noted in terms of blood products transfused within 24 hours in those receiving Group A over AB. Development of acute respiratory distress syndrome (ARDS), but not mortality, was higher within the AB cohort. No hemolytic or transfusion associated-ARDS reactions were noted in either group. ARDS; RBC transfusion volumes and head AIS were independently associated with mortality. CONCLUSION Utilization of Group A plasma for emergency blood resuscitation is a safe option which may alleviate potential shortages of AB plasma. PMID:25200933

Cardiac contusion is a potentially fatal complication of blunt chest trauma. The effects of a combination of quercetin and methylprednisolone against trauma-induced cardiac contusion were studied. Thirty-five female Sprague-Dawley rats were divided into five groups (n=7) as follows: sham, cardiac contusion with no therapy, treated with methylprednisolone (30 mg/kg on the first day, and 3 mg/kg on the following days), treated with quercetin (50 mg·kg−1·day−1), and treated with a combination of methylprednisolone and quercetin. Serum troponin I (Tn-I) and tumor necrosis factor-alpha (TNF-α) levels and cardiac histopathological findings were evaluated. Tn-I and TNF-α levels were elevated after contusion (P=0.001 and P=0.001). Seven days later, Tn-I and TNF-α levels decreased in the rats treated with methylprednisolone, quercetin, and the combination of methylprednisolone and quercetin compared to the rats without therapy, but a statistical significance was found only with the combination therapy (P=0.001 and P=0.011, respectively). Histopathological degeneration and necrosis scores were statistically lower in the methylprednisolone and quercetin combination group compared to the group treated only with methylprednisolone (P=0.017 and P=0.007, respectively). However, only degeneration scores were lower in the combination therapy group compared to the group treated only with quercetin (P=0.017). Inducible nitric oxide synthase positivity scores were decreased in all treatment groups compared to the untreated groups (P=0.097, P=0.026, and P=0.004, respectively). We conclude that a combination of quercetin and methylprednisolone can be used for the specific treatment of cardiac contusion. PMID:25098616

Abstract A delay in diagnosing hollow viscus injury (HVI) causes an increase in mortality and morbidity. HVI remains a challenge to diagnose, and there is no specific diagnostic biomarker for HVI. We evaluated the utility of intestinal fatty acid–binding protein (I-FABP) in diagnosing HVI in blunt trauma patients. Within a 5-year period, 93 consecutive patients with clinically suspected HVI at our trauma center were prospectively enrolled. The diagnostic performance of I-FABP for HVI was compared with that of other various parameters (physical, laboratory, and radiographic findings). HVI was diagnosed in 13 patients (14%), and non-HVI was diagnosed in 80 patients (86%). The level of I-FABP was significantly higher in patients with HVI than in those with non-HVI (P = 0.014; area under the curve, 0.71). The sensitivity, specificity, positive predictive value, and negative predictive value were 76.9%, 70.0%, 29.4%, and 94.9%, respectively (P = 0.003). However, all other biomarkers were not significantly different between the groups. Presence of extraluminal air, bowel wall thickening on computed tomography (CT), and peritonitis signs were significantly higher in patients with HVI (P < 0.05). Of 49 patients (52.7%) who had a negative I-FABP and negative peritonitis signs, none developed HVI (sensitivity, 100%; negative predictive value, 100%). This is the first study that demonstrated the diagnostic value of a biomarker for HVI. I-FABP has a higher negative predictive value compared to traditional diagnostic tests. Although the accuracy of I-FABP alone was insufficient, the combination of I-FABP and other findings can enhance diagnostic ability. PMID:28272208

There are differing recommendations in the literature regarding cervical spine imaging in alert, asymptomatic geriatric patients. Previous studies also have not used computed tomography routinely. Given that cervical radiographs may miss up to 60 per cent of fractures, the incidence of cervical spine injuries in this population and its implications for clinical management are unclear. We conducted a retrospective study of blunt trauma patients 65 years and older who were alert, asymptomatic, hemodynamically stable, and had normal neurologic examinations. For inclusion, patients were required to have undergone computed tomography and plain radiographs. The presence and anatomic location of potentially distracting injuries or pain were recorded. Two hundred seventy-four patients were included, with a mean age of 76 +/- 10 years. The main mechanisms of injury were falls (51%) and motor vehicle crashes (41%). Nine of 274 (3%) patients had cervical spine injuries. The presence of potentially distracting injuries above the clavicles was associated with cervical injury when compared with patients with distracting injuries in other anatomic locations or no distracting injuries (8/115 vs 1/159, P = 0.03). There was no association of cervical spine injury with age greater or less than 75 years or with mechanism of injury. The overall incidence of cervical spine injury in the alert, asymptomatic geriatric population is low. The risk is increased with a potentially distracting injury above the clavicles. Patients with distracting injuries in other anatomic locations or no distracting injuries may not need routine cervical imaging.

This article examines why Southeast Asian American adolescents and emerging adults in two urban settings prefer to use “blunts,” or hollowed-out cigars filled with marijuana, over other methods of drug intake. Rationales for preferring blunts were both instrumental and social. Blunts allowed users to more easily share marijuana, the preferred drug among their peers, and protected against potential adverse effects associated with the “high.” Blunts also allowed users to identify with the dominant style of drug use and differentiate themselves from users of stigmatized drugs such as crack cocaine and methamphetamine. This article highlights the importance of drug-intake methods in the formation and performance of drug-using behaviors among adolescents, emerging adults, and members of ethnic minority subgroups.

, severe permanent hemiplegia in two cases, and minimal or no sequels in two cases. Following blunt trauma, arteriography of supraaortic vessels should be performed to detect BCAD in any patient with immediate or delayed neurologic symptoms that cannot be explained by CT-scan findings. To better understand the natural course of these lesions and define the indications for surgery, we propose a three-grade classification according to arteriographic findings. If surgery is undertaken, vein grafting should be performed following resection of the carotid artery lesions.

IMPORTANCE Increased use of computed tomography (CT) in children is concerning owing to the cancer risk from ionizing radiation, particularly in children younger than 2 years. A guardian report that a child is acting abnormally is a risk factor for clinically important traumatic brain injury (ciTBI) and may be a driving factor for CT use in the emergency department. OBJECTIVE To determine the prevalence of ciTBIs and TBIs in children younger than 2 years with minor blunt head trauma and a guardian report of acting abnormally with (1) no other findings or (2) other concerning findings for TBI. DESIGN, SETTING, AND PARTICIPANTS Secondary analysis of a large, prospective, multicenter cohort study that included 43 399 children younger than 18 years with minor blunt head trauma evaluated in 25 emergency departments. The study was conducted on data obtained between June 2004 and September 2006. Data analysis was performed between August 21, 2014, and March 9, 2015. EXPOSURES A guardian report that the child was acting abnormally after minor blunt head trauma. MAIN OUTCOMES AND MEASURES The prevalence of ciTBI (defined as death, neurosurgery, intubation for >24 hours, or hospitalization for ≥2 nights in association with TBI on CT imaging) and TBI on CT imaging in children with a guardian report of acting abnormally with (1) no other findings and (2) other concerning findings for TBI. RESULTS Of 43 399 children in the cohort study, a total of 1297 children had reports of acting abnormally, of whom 411 (31.7%) had this report as their only finding. Reported as percentage (95% CI), 1 of 411 (0.2% [0–1.3%]) had a ciTBI, and 4 TBIs were noted on the CT scans in 185 children who underwent imaging (2.2% [0.6%–5.4%]). In children with reports of acting abnormally and other concerning findings for TBI, 29 of 886 (3.3% [2.2%–4.7%]) had ciTBIs and 66 of 674 (9.8% [7.7%–12.3%]) had TBIs on CT. CONCLUSIONS AND RELEVANCE Clinically important TBIs are very uncommon, and TBIs

There is very limited knowledge about how long perimortem fracture characteristics persist into the postmortem interval (PMI). Therefore, in this study, 60 porcine long bones were exposed to natural taphonomic conditions and fractured with a steel bone breaking apparatus every 28 days throughout a 141-day period. Differences between macroscopic blunt force trauma fracture characteristics (fracture angle, surface morphology, and outline) were examined to determine if they varied over time or in relationship to bone moisture content (ash weight) and overall assessment. There are significant relationships between (1) PMI and percent ash weight (%AW), fracture surface, and fracture angle and (2) %AW and fracture surface and fracture angle. Bone moisture content correlates significantly with fracture morphology and other characteristics commonly used by forensic anthropologists to determine the timing of traumatic injuries. However, fracture characteristics normally associated with perimortem trauma can persist long into the PMI.

Background Although emergency resuscitative thoracotomy is performed as a salvage maneuver for critical blunt trauma patients, evidence supporting superior effectiveness of emergency resuscitative thoracotomy compared to conventional closed-chest compressions remains insufficient. The objective of this study was to investigate whether emergency resuscitative thoracotomy at the emergency department or in the operating room was associated with favourable outcomes after blunt trauma and to compare its effectiveness with that of closed-chest compressions. Methods This was a retrospective nationwide cohort study. Data were obtained from the Japan Trauma Data Bank for the period between 2004 and 2012. The primary and secondary outcomes were patient survival rates 24 h and 28 d after emergency department arrival. Statistical analyses were performed using multivariable generalized mixed-effects regression analysis. We adjusted for the effects of different hospitals by introducing random intercepts in regression analysis to account for the differential quality of emergency resuscitative thoracotomy at hospitals where patients in cardiac arrest were treated. Sensitivity analyses were performed using propensity score matching. Results In total, 1,377 consecutive, critical blunt trauma patients who received cardiopulmonary resuscitation in the emergency department or operating room were included in the study. Of these patients, 484 (35.1%) underwent emergency resuscitative thoracotomy and 893 (64.9%) received closed-chest compressions. Compared to closed-chest compressions, emergency resuscitative thoracotomy was associated with lower survival rate 24 h after emergency department arrival (4.5% vs. 17.5%, respectively, P < 0.001) and 28 d after arrival (1.2% vs. 6.0%, respectively, P < 0.001). Multivariable generalized mixed-effects regression analysis with and without a propensity score-matched dataset revealed that the odds ratio for an unfavorable survival rate after 24 h

Many with schizophrenia report exposure to trauma which may reduce health-related quality of life (HRQOL). To explore whether different forms of trauma are linked to different domains of HRQOL, and whether multiple trauma experiences have a cumulative effect, trauma history was gathered along with a measure of HRQOL among 102 adults with schizophrenia spectrum disorders. Participants were divided into those with and without report of sexual trauma, assault trauma, and trauma related to harm to others. Analysis of variance revealed that participants endorsing sexual trauma had poorer levels of general health, vitality, emotional-related role function, and mental health. Participants endorsing trauma related to harm to others reported poorer physical-related role function, general health, social function, and emotional-related role function. No evidence was found linking assaulted-related trauma to HRQOL. Greater numbers of trauma were related to poorer HRQOL. Results suggest differing forms of trauma may individually and cumulatively impact HRQOL in schizophrenia.

Abstract Effective analgesia in the early stages after any major traumatic event remains pivotal to optimal trauma management. For patients with significant thoracic injuries, this is paramount to ensure ongoing efficient respiratory function. The aim of this study was to investigate the use of analgesic modes in the management of patients with a primary thoracic injury and blunt mechanism of injury. By understanding variables that influence the use of varying analgesic modes and influence the development of pulmonary complications, there should be more uniform evidence-based prescription in the future. This retrospective study considered analgesic use in patients admitted after blunt thoracic injuries at one major trauma center over a 2-year period. Pulmonary complications measured included both infective and ventilator-associated failure. Univariate and multivariate analyses were used to identify patient and injury severity characteristics and their association with respiratory complications. A total of 401 cases were reviewed and analyzed: 159 received Patient Controlled Analgesia (PCA), 32 received PCA and epidural analgesia (EA), 6 received EA alone, and 204 received interval-administered analgesia. There were no significant differences in the rates of complication when compared between analgesic modes. Patients who developed pneumonia had significantly increased number of thoracic fractures and underlying organ injury (P < 0.05). Logistic regression analysis highlighted duration of intercostal drain insertion (OR 1.377, P = 0.001) and premorbid cardiac disease (OR 2.624, P = 0.042) and ICU length of stay (OR: 1.146, P < 0.001) as significant predictors of developing pneumonia in this patient group. Examining the different analgesic modes, this study failed to identify a particular analgesic mode that was more effective in preventing pulmonary complications in blunt thoracic injuries. However, variables that may influence usage of different

Trauma comes as a result of the subject's exposure to extremely negative and stressful events, such as natural or human-provoked catastrophes, wars, serious injuries, violent deaths, tortures, terrorist attacks, rapes and other sexual crimes. A child's exposure to traumatic circumstances of this level during the crucial period of self-structuring creates rather difficult conditions for its development. Moreover, if the child does not have the opportunity to elaborate and analyze all these stressful conditions and put them into words, serious consequences, both psychological and somatic, may occur in adult life. Specific factors and child characteristics, namely, the age, the developmental stage within which the trauma occurs, its type (physical or sexual abuse, neglect or traumatic social events), frequency, duration and intensity, have been proved to seriously affect the trauma's consequences. The immediate emotional impact of trauma may include isolation, fear, feeling of weakness or loss of the sense of confidence. Moreover, mood disorders such as depression and withdrawal, negative effects on cognitive ability, language development and academic performance, difficulties in creating a secure link and post-traumatic stress disorder (PTSD) are also observed. The long-term consequences for the individual's mental health can be expressed through the following: post-traumatic stress disorder (PTSD) combined or not with depression and anxiety disorder, mood disorders, personality disorders, poor control of impulsions, dissociation disorder, psychotic disorder. Finally, apart from the dramatic impact of trauma on the person itself, there is also a high social cost to be paid as a result of the individual's poor adjustment and dysfunction in the community. Early support and intervention in the child's environment may significantly minimize the negative effects of trauma. Beyond the expression of genes, good maternal care as well as psychological support, lead to normal

Greater risk of post-traumatic stress disorder (PTSD) is seen in individuals exposed to interpersonal traumatic events. Based on an attachment perspective, interpersonal trauma exposure may activate one's attachment insecurity system and disrupt affect, behaviour and interpersonal function, which may in turn create more difficulties to cope with interpersonal traumas and exacerbate PTSD symptomatology. The present study examined whether attachment anxiety relative to attachment avoidance would be a stronger predictor of greater PTSD symptoms following interpersonal traumas versus impersonal traumas in a Taiwanese sample. One hundred and sixty-two trauma-exposed Taiwanese young adults completed the measures of symptoms of depression, anxiety and PTSD, and attachment anxiety and attachment avoidance. In this Taiwanese study, higher attachment anxiety was observed in individuals who were exposed to interpersonal traumas. The interpersonal trauma group reported greater PTSD symptoms than did the impersonal trauma group. Specifically, after controlling for age, occurrence of trauma and distress of trauma, attachment anxiety, but not attachment avoidance, predicted more PTSD total severity and avoidance symptoms in the interpersonal trauma group. The findings may be pertinent to attachment anxiety-related hyperactivating strategies, as well as specific cultural values and a forbearance strategy applied to regulate traumatic distress in a collectivist society.

Since the 1970s, the management of blunt splenic trauma has evolved from almost exclusive surgical management to selective use of nonsurgical management in hemodynamically stable patients. Understanding of the spleen's immunologic importance in protection against overwhelming postsplenectomy infection led to development first of surgical techniques for splenic salvage and later to protocols for nonsurgical management of adults with blunt splenic injury. The evolution of nonsurgical management has resulted in new patterns of postsplenic trauma complications.This article describes a pancreatic pseudocyst, one of several described delayed complications of nonsurgical management of blunt splenic trauma. Along with missed splenic injury and delayed rupture, the development of a splenic pseudocyst represents challenges for any multidisciplinary team involved in trauma care. Detection and management of these complications is discussed, as is postsplenectomy vaccination and return to activity.

Enhanced threat-related processing is associated with both elevated anxiety and childhood exposure to trauma. Given the paucity of evidence regarding the effects of childhood and adult trauma exposure on subsequent psychophysiological processes in the absence of psychopathology, we investigated the relative impacts of childhood interpersonal and non-interpersonal trauma, as well as adult trauma exposure on neural processing of threat in healthy adults. We measured peak amplitudes of the N170 face-sensitive visual ERP component response to non-conscious and conscious Angry (threat) versus Happy (non-threat, positive) and Neutral (non-threat baseline) faces at temporo-occipital sites (right-T6; left-T5) in 489 psychiatrically asymptomatic adults (aged 18-70 years, 54% women, 94% right-handed). N170 peak amplitude differences between Angry vs Happy or Neutral faces were calculated and subjected to hierarchical multiple regression analysis, with trauma types (childhood interpersonal, childhood non-interpersonal and adult trauma) entered as predictors of interest. After controlling for sociodemographic and health factors, N170 peak amplitudes for non-conscious Angry vs Happy faces were inversely associated with childhood interpersonal trauma at T6 and adult trauma exposure at T5. Post-hoc repeated measures ANOVA indicated that unlike adults without trauma exposure, trauma-exposed adults failed to show significantly reduced N170 responses to Happy relative to Angry faces during non-conscious processing. This suggests that childhood interpersonal and adult trauma exposure are associated with a failure to differentiate between non-threat or positive and threat-related emotion cues. This is consistent with generalised hypervigilance seen in PTSD, and suggests trauma exposure is associated with a generalized heightened responsivity to non-conscious non-threat or positive as well as threat-related emotion cues in psychiatrically healthy adults.

Simple radiography is the best diagnostic tool for rib fractures caused by chest trauma, but it has some limitations. Thus, other tools are also being used. The aims of this study were to investigate the effectiveness of ultrasonography (US) for identifying rib fractures and to identify influencing factors of its effectiveness. Between October 2003 and August 2007, 201 patients with blunt chest trauma were available to undergo chest radiographic and US examinations for diagnosis of rib fractures. The two modalities were compared in terms of effectiveness based on simple radiographic readings and US examination results. We also investigated the factors that influenced the effectiveness of US examination. Rib fractures were detected on radiography in 69 patients (34.3%) but not in 132 patients. Rib fractures were diagnosed by using US examination in 160 patients (84.6%). Of the 132 patients who showed no rib fractures on radiography, 92 showed rib fractures on US. Among the 69 patients of rib fracture detected on radiography, 33 had additional rib fractures detected on US. Of the patients, 76 (37.8%) had identical radiographic and US results, and 125 (62.2%) had fractures detected on US that were previously undetected on radiography or additional fractures detected on US. Age, duration until US examination, and fracture location were not significant influencing factors. However, in the group without detected fractures on radiography, US showed a more significant effectiveness than in the group with detected fractures on radiography (P=0.003). US examination could detect unnoticed rib fractures on simple radiography. US examination is especially more effective in the group without detected fractures on radiography. More attention should be paid to patients with chest trauma who have no detected fractures on radiography. PMID:28119889

Targeted temperature management (TTM) improves survival and neurological outcome after nontraumatic cardiac arrest. However, TTM is not used widely after traumatic cardiac arrest because of concerns that it might exacerbate bleeding. We report the use of postarrest TTM after repair of blunt myocardial rupture. A 48-year-old man was admitted after being rescued from a major traffic accident by the local emergency service. Focused sonography showed pericardial fluid without cardiac tamponade. Computed tomography showed a large hematoma in the anterior mediastinum associated with hemopericardium. The patient developed cardiac arrest during the operative preparations. Repeat bedside sonography revealed a large pericardial effusion and signs of cardiac tamponade. Spontaneous circulation was restored after ultrasound-guided pericardiocentesis. His Glasgow Coma Scale score was 3. The patient was transported promptly to the operating room and underwent median sternotomy without cardiopulmonary bypass. A rupture of the junction of the superior vena cava/right atrium and left atrial appendage was detected and was closed by direct suturing. Immediately after return to the intensive care unit, we performed TTM (target body temperature 34.5°C) using a surface-cooling device at 4 hours postarrest. TTM was maintained for 24 hours and controlled gradual rewarming was then initiated. He regained consciousness 36 hours postrewarming with limited speech ability. The patient recovered with no further cardiac events and was discharged 3 weeks after admission, with no other serious complications. The patient was neurologically intact (cerebral performance category 1) at 6 months of follow-up. This case demonstrates the potential benefit and applicability of postarrest TTM in patients after repair of blunt myocardial rupture.

PurposeTo compare the impact of proximal or distal splenic artery embolisation versus that of splenectomy on splenic immune function as measured by IgM memory B cell levels.Materials and MethodsPatients with splenic trauma who were treated by splenic artery embolisation (SAE) were enrolled. After 6 months splenic volume was assessed by CT, and IgM memory B cells in peripheral blood were measured and compared to a local normal reference population and to a post-splenectomy population.ResultsOf the 71 patients who underwent embolisation, 38 underwent proximal embolisation, 11 underwent distal embolisation, 22 patients were excluded, 1 had both proximal and distal embolisation, 5 did not survive and 16 did not return for evaluation. There was a significant difference between splenectomy and proximal or distal embolisation and a trend towards greater preservation of IgM memory B cell number in those with distal embolisation—a difference that could not be attributed to differences in age, grade of injury or residual splenic volume.ConclusionIgM memory B cell levels are significantly higher in those treated with SAE compared to splenectomy. Our data provide evidence that splenic embolisation should reduce immunological complications of spleen trauma and suggest that distal embolisation may maintain better function.

We hypothesized that elevated base deficit (BD) ≥ 4 mEq/L upon admission could be associated with an altered inflammatory response, which in turn may impact differential clinical trajectories. Using clinical and biobank data from 472 blunt trauma survivors, 154 patients were identified after excluding patients who received prehospital IV fluids or had alcohol intoxication. From this subcohort, 84 patients had a BD ≥ 4 mEq/L and 70 patients with BD < 4 mEq/L. Three samples within the first 24 h were obtained from all patients and then daily up to day 7 after injury. Twenty-two cytokines and chemokines were assayed using Luminex™ and were analyzed using two-way ANOVA and dynamic network analysis (DyNA). Multiple mediators of the innate and lymphoid immune responses in the BD ≥ 4 group were elevated differentially upon admission and up to 16 h after injury. DyNA revealed a higher, sustained degree of interconnectivity of the inflammatory response in the BD ≥ 4 patients during the initial 16 h after injury. These results suggest that elevated admission BD is associated with differential immune/inflammatory pathways, which subsequently could predispose patients to follow a complicated clinical course.

Traumatic hemothorax commonly occurs accompanied by organ damage, such as rib fractures, lung injury and diaphragm rupture. Our reported patient was a 61-year-old man who fell down from a stepladder about 1 meter in height, resulting in a heavy blow to the left abdomen. He consulted a clinic because of left chest pain the next day and was transported to the emergency center of our hospital on diagnosis of hemothorax with hemorrhagic shock.On computed tomography scanning with contrast medium, left hemothorax without rib fracture, diaphragm rupture or obvious organ injury was evident. We found only bleeding to the thoracic space from a branch of the left inferior phrenic artery without involvement of the abdomen. The patient underwent percutaneous angiography and embolization for hemostasis, and subsequently thoracotomy in order to check the active bleeding and remove the hematoma to improve respiratory. As thoracotomy findings, we found damage of a branch of the left inferior phrenic artery to the thoracic space without diaphragm rupture, and sutured the lesion. Such active intervention followed by surgical procedures was effective and should be considered for rare occurrences like the present case. We must consider not only traumatic diaphragm rupture, but also vascular damage by pressure trauma as etiological factors for hemothorax.

We herein report an extremely rare case of a patient chylothorax at an interval of 20 years after thoracic vertebrae fractures, who underwent a successful thoracoscopic thoracic duct ligation and pleurodesis. A 51-year-old man was referred to our hospital with shortness of breath on effort about 1 month after participating in archery. Twenty years previously, he was involved in a traffic accident. At that time, the patient sustained trauma to the spine and suffered a spinal injury, thus resulting in paralysis in the lower part of his body. A chest roentgenogram and computed tomogram revealed a large amount of bilateral pleural effusion. After thoracentesis was performed, a diagnosis of chylothorax was made and the patient was hospitalized. Conservative management by a low-fat diet proved to be unsuccessful. The patient did not request pleurodesis, because pleural adhesions might impair pulmonary function. As a result, we decided to perform surgery. On the right side, we performed video-assisted thoracoscopic surgery by clipping the thoracic duct and applying an absorbable sealing material. Thereafter, pleurodesis was performed and OK-432 was instilled. Thereafter, the pleural fluid flow was almost completely stopped. On the left side, pleurodesis was effective. The patient has since remained symptom free and has been followed up on an outpatient basis for 9 months after the 100th postoperative day. We assumed that the chylothorax in this case was related to the earlier traffic accident.

According to the CDC, the leading cause of death for both men and women between the ages of 5 and 44 is traumatic injury. Blood loss is the primary cause of death at acute time points post trauma. Early intervention is critical to save lives, and yet there are no treatments to stop internal bleeding that can be deployed in the field. In this work, we developed hemostatic nanoparticles that are stable at high temperatures (50 °C for 7 days) and are still effective at stopping bleeding and improving survival over the one hour time period in a rat liver injury model. These particles are exceptionally simple: PLA-based nanospheres functionalized with PEG terminated with variants of the RGD motif. This simple system can be stored at temperatures up to 50°C and maintain size, shape, and efficacy. The particles lead to a reduction in bleeding and increased acute survival with significance compared to both control particles and saline. Overall, these hemostatic nanoparticles offer an important step towards an immediate intervention in the field to stop bleeding and improve survival. PMID:27672679

Etiological models of social anxiety disorder (SAD) suggest that early childhood trauma contributes to the development of this disorder. However, surprisingly little is known about the link between different forms of childhood trauma and adult clinical symptoms in SAD. This study (1) compared levels of childhood trauma in adults with generalized SAD versus healthy controls (HCs), and (2) examined the relationship between specific types of childhood trauma and adult clinical symptoms in SAD. Participants were 102 individuals with generalized SAD and 30 HCs who completed measures of childhood trauma, social anxiety, trait anxiety, depression, and self-esteem. Compared to HCs, individuals with SAD reported greater childhood emotional abuse and emotional neglect. Within the SAD group, childhood emotional abuse and neglect, but not sexual abuse, physical abuse, or physical neglect, were associated with the severity of social anxiety, trait anxiety, depression, and self-esteem.

Diet-induced thermogenesis (DIT) is believed to be largely related to ATP production, which is dependent on phosphorus (P) availability. We aimed to test the effect of P addition on DIT of lean and overweight/obese healthy subjects. DIT was measured with or without P in 10 lean and 13 overweight/obese adults in a double-blind randomized cross-over pilot study with one week washout period. After 10 h overnight fast, resting metabolic rate, respiratory quotient, and substrate utilization were measured at fasting and every 30 min for 3 h after subjects drank a standardized glucose solution, with P (500 mg) or placebo pills. Subjective ratings of hunger and satiety were assessed before and after the end of each experiment using validated visual analogue scale (VAS) questionnaires. Overweight/obese subjects had a blunted DIT with placebo, while P supplementation induced a 23% increase in their DIT area under the curve (p < 0.05), which was associated with a significant increase in carbohydrate oxidation. Subjects had lower appetite following P supplementation, which was expressed as a significantly (p = 0.02) lower desire to eat a meal (4.0 ± 0.7 cm) compared with placebo (5.8 ± 0.9 cm). P supplementation recovers the blunted diet-induced thermogenesis in overweight and obese subjects and enhances their postprandial satiety.

The brain continues to develop through adolescence when excessive alcohol consumption is prevalent in humans. We hypothesized that binge drinking doses of ethanol during adolescence will cause changes in brain ethanol responses that persist into adulthood. To test this hypothesis Wistar rats were treated with an adolescent intermittent ethanol (AIE; 5 g/kg, i.g. 2 days on–2 days off; P25–P54) model of underage drinking followed by 25 days of abstinence during maturation to young adulthood (P80). Using markers of neuronal activation c-Fos, EGR1, and phophorylated extracellar signal regulated kinase (pERK1/2), adult responses to a moderate and binge drinking ethanol challenge, e.g., 2 or 4 g/kg, were determined. Adult rats showed dose dependent increases in neuronal activation markers in multiple brain regions during ethanol challenge. Brain regional responses correlated are consistent with anatomical connections. AIE led to marked decreases in adult ethanol PFC (prefrontal cortex) and blunted responses in the amygdala. Binge drinking doses led to the nucleus accumbens (NAc) activation that correlated with the ventral tegmental area (VTA) activation. In contrast to other brain regions, AIE enhanced the adult NAc response to binge drinking doses. These studies suggest that adolescent alcohol exposure causes long-lasting changes in brain responses to alcohol that persist into adulthood. PMID:25727639

Binge drinking doses led to the nucleus accumbens (NAc) activation that correlated with the ventral tegmental area (VTA) activation. In contrast to other brain regions, AIE enhanced the adult NAc response to binge drinking doses. These studies suggest that adolescent alcohol exposure causes long-lasting changes in brain responses to alcohol that persist into adulthood.
Introduction Helicopter emergency medical services with a physician (HEMS) has been provided in Japan since 2001. However, HEMS and its possible effect on outcomes for severe trauma patients have still been debated as helicopter services require expensive and limited resources. Our aim was to analyze the association between the use of helicopters with a physician versus ground services and survival among adults with serious traumatic injuries. Methods This multicenter prospective observational study involved 24,293 patients. All patients were older than 15 years of age, had sustained blunt or penetrating trauma and had an Injury Severity Score (ISS) higher than 15. All of the patient data were recorded between 2004 and 2011 in the Japan Trauma Data Bank, which includes data from 114 major emergency hospitals in Japan. The primary outcome was survival to discharge from hospitals. The intervention was either transport by helicopter with a physician or ground emergency services. Results A total of 2,090 patients in the sample were transported by helicopter, and 22,203 were transported by ground. Overall, 546 patients (26.1%) transported by helicopter died compared to 5,765 patients (26.0%) transported by ground emergency services. Patients transported by helicopter had higher ISSs than those transported by ground. In multivariable logistic regression, helicopter transport had an odds ratio (OR) for survival to discharge of 1.277 (95% confidence interval (CI), 1.049 to 1.556) after adjusting for age, sex, mechanism of injury, type of trauma, initial vital signs (including systolic blood pressure, heart rate and respiratory rate), ISS and prehospital treatment (including intubation, airway protection maneuver and intravenous fluid). In the propensity score–matched cohort, helicopter transport was associated with improved odds of survival compared to ground transport (OR, 1.446; 95% CI, 1.220 to 1.714). In conditional logistic regression, after adjusting for

The present study examined whether the relationship between childhood gender nonconformity and sexual victimization in adulthood among lesbian, gay, and bisexual (LGB) same-sex attracted men and women is mediated by experiences with childhood trauma experiences by an adult family member. Data are based on a survey among same-sex attracted individuals (N= 2,352; 1,396 men and 956 women;Mage= 44.97) recruited from an online research panel. Participants completed an online questionnaire consisting of existing scales. Sixteen percent of the participants reported that they had experienced sexual victimization as an adult. There were gender differences: Men reported less childhood gender nonconformity and women more often reported experiences with childhood trauma by an adult family member and sexual victimization as an adult. Bootstrapped mediation analysis and follow-up moderated mediation analyses showed that childhood trauma significantly mediated the relation between childhood gender nonconformity and experiences of sexual victimization for men but not for women. In other words, for men higher levels of childhood gender nonconformity predicted experiences with childhood trauma by an adult family member, which in turn predicted the higher prevalence of sexual victimization. Implementations of these findings are that interventions aimed at increasing the social acceptance of gender nonconformity might also lower the levels of childhood trauma and sexual victimization among gay and bisexual men. Professionals working with children (and especially with boys) should be aware of the impact of gender nonconformity on childhood trauma and experiences of sexual victimization later in life.

Over a million children are subjected to some form of trauma in the United States every year. Early trauma has been shown to have deleterious effects on cardiovascular health in adulthood. However, the presence of strong social relationships as an adult can buffer an individual against many of the harmful effects of early trauma. Furthermore, the perception of social isolation has been shown to be a significant risk factor for the development of cardiovascular disease and is a strong predictor of all cause mortality. One likely mechanism thought to underlie the influence of perceived isolation on health is changes in arterial stiffness. One of the more widely used measures of arterial stiffness in older individuals is pulse pressure. The goal of the present study was to determine whether early childhood trauma is associated with elevations on pulse pressure. Furthermore, this study sought to determine whether perceived social isolation moderates the relationship between early trauma and pulse pressure. Results revealed that individuals with low perceived social isolation displayed no significant relationship between early trauma and pulse pressure. However, individuals who reported higher levels of perceived isolation showed a significant positive association between early trauma and pulse pressure. Therefore, the detrimental effects of early trauma may be partially dependent upon the quality of social relationships as an adult.

Background Although the association between psychological trauma and early maladaptive schemas (EMS) is well established in the literature, no study to date has examined the relationship of EMS to PTSD and psychopathologies beyond depression and anxiety in a sample of adult survivors of interpersonal trauma. This information may be useful in helping our understanding on how to best treat interpersonal trauma. Objective We set out to investigate the association between EMS and common forms of psychopathology in a sample of women with a history of interpersonal trauma (n=82). We have hypothesised that survivors of interpersonal trauma will present with elevated EMS scores compared to a non-clinical control group (n=78). We have also hypothesised that unique schemas will be associated with unique psychopathological entities and that subgroups of interpersonal trauma survivors would be present in our sample, with subgroups displaying different profiles of schema severity elevations. Method Participants completed measures of trauma, psychopathology, dissociation, self-esteem, and the Young Schema Questionnaire. Results It was found that survivors of interpersonal trauma displayed elevated EMS scores across all 15 schemas compared to controls. Although the pattern of associations between different psychopathological features and schemas appears to be rather complex, schemas in the domains of Disconnection and Impaired Autonomy formed significant associations with all psychopathological features in this study. Conclusions Our findings support the usefulness of cognitive behavioural interventions that target schemas in the domains of Disconnection and Impaired Autonomy in an effort to modify existing core beliefs and decrease subsequent symptomatology in adult survivors of interpersonal trauma. Highlights of the article Interpersonal trauma survivors are distinguished primarily by a generalised elevation of their maladaptive schemas, rather than a unique schema profile

Objective Guidelines suggest that Traumatic Brain Injury (TBI) related hospitalizations are best treated at Level I or II trauma centers because of continuous neurosurgical care in these settings. This population-based study examines TBI hospitalization treatment paths by age groups. Methods Trauma center utilization and transfers by age groups were captured by examining the total number of TBI hospitalizations from National Inpatient Sample (NIS) and the number of TBI hospitalizations and transfers in the Trauma Data Bank National Sample Population (NTDB-NSP). TBI cases were defined using diagnostic codes. Results Of the 351,555 TBI related hospitalizations in 2012, 47.9% (n = 168,317) were directly treated in a Level I or II trauma center, and an additional 20.3% (n = 71,286) were transferred to a Level I or II trauma center. The portion of the population treated at a trauma center (68.2%) was significantly lower than the portion of the U.S. population who has access to a major trauma center (90%). Further, nearly half of all transfers to a Level I or II trauma center were adults aged 55 and older (p < 0.001) and that 20.2% of pediatric patients arrive by non-ambulatory means. Conclusion Utilization of trauma center resources for hospitalized TBIs may be low considering the established lower mortality rate associated with treatment at Level I or II trauma centers. The higher transfer rate for older adults may suggest rapid decline amid an unrecognized initial need for a trauma center care. A better understanding of hospital destination decision making is needed for patients with TBI. PMID:26986195
Introduction Although a plethora of studies have delineated the relationship between childhood trauma and onset, symptom severity, and course of depression and anxiety disorders, there has been little evidence that childhood trauma may lead to interpersonal problems among adult patients with depression and anxiety disorders. Given the lack of prior research in this area, we aimed to investigate characteristics of interpersonal problems in adult patients who had suffered various types of abuse and neglect in childhood. Methods A total of 325 outpatients diagnosed with depression and anxiety disorders completed questionnaires on socio-demographic variables, different forms of childhood trauma, and current interpersonal problems. The Childhood Trauma Questionnaire (CTQ) was used to measure five different forms of childhood trauma (emotional abuse, emotional neglect, physical abuse, physical neglect, and sexual abuse) and the short form of the Korean-Inventory of Interpersonal Problems Circumplex Scale (KIIP-SC) was used to assess current interpersonal problems. We dichotomized patients into two groups (abused and non-abused groups) based on CTQ score and investigated the relationship of five different types of childhood trauma and interpersonal problems in adult patients with depression and anxiety disorders using multiple regression analysis. Result Different types of childhood abuse and neglect appeared to have a significant influence on distinct symptom dimensions such as depression, state-trait anxiety, and anxiety sensitivity. In the final regression model, emotional abuse, emotional neglect, and sexual abuse during childhood were significantly associated with general interpersonal distress and several specific areas of interpersonal problems in adulthood. No association was found between childhood physical neglect and current general interpersonal distress. Conclusion Childhood emotional trauma has more influence on interpersonal problems in adult patients with

Several studies have demonstrated that lesbian and bisexual women are more likely than heterosexual women to report childhood abuse and adult sexual assault. It is unknown, however, which sexual minority women are most likely to experience such abuse. We recruited adult sexual minority women living in the US through electronic fliers sent to listservs and website groups inviting them to complete an online survey (N=1,243). We examined differences in both childhood abuse and adult sexual assault by women’s current gender identity (i.e., butch, femme, androgynous, or other) and a continuous measure of gender expression (from butch/masculine to femme/feminine), adjusting for sexual orientation identity, age, education, and income. Results indicated that a more butch/masculine current self-assessment of gender expression, but not gender identity, was associated with more overall reported childhood trauma. Although one aspect of gender expression, a more butch/masculine gender role, was associated with adult sexual assault, feminine appearance and a femme gender identity also significantly predicted adult sexual assault. These findings highlight the significance of gender identity and expression in identifying women at greater risk for various abuse experiences. PMID:24003263

The development of PTSD has been shown to be dependent on a variety of factors, including ethnicity, whether the trauma was experienced as a child or adult, and acculturation. Using 104 Latinos who had completed treatment for substance abuse disorder(s), this study compared PTSD symptomatology for individuals reporting their worst traumatic event (WTE) in childhood versus adulthood. The moderating effect of acculturation was also examined. Although many studies have reported on the pernicious effects of childhood trauma, very few have provided direct comparisons of child and adult trauma in terms of PTSD symptoms. Results indicated that those reporting their WTE in childhood had greater PTSD symptomatology than those reporting in adulthood. Acculturation moderated the relationship between timing of the trauma and PTSD symptoms. Specifically, those who reported their WTE in childhood and had the lower levels of acculturation reported the higher number of PTSD symptoms. Implications and future directions are discussed.

There are many risk factors that make the transition to parenthood difficult, even in the best of circumstances. One such risk factor is the experience of parental childhood trauma, which has the potential to affect the parent/child relationship, both in terms of attachment style parental reflective functioning. This study aims to expand on the line of research concerned with the effects that trauma has once that child transitions into adulthood and into parenthood by looking at the role that the experience of trauma and adult attachment has in relation to parental reflective functioning. This study assessed mothers (N = 125) by using the CTQ (childhood experience of trauma), ECR (adult attachment), and the PRFQ (parental RF). Our study found that in the presence of physical neglect, insecure attachment had a particularly deleterious effect on maternal reflective functioning. This relationship was not as strong in the absence of physical neglect. PMID:28392776

Despite an increased awareness regarding the prevalence and impact of childhood trauma, especially childhood sexual abuse (CSA), few studies examine the clinical reporting of such childhood experiences. This study compared the prevalence of childhood trauma recorded in individual's clinical notes to those ascertained with a structured validated questionnaire, examined which forms of childhood trauma were less likely to be reported to the treating mental health team and established which demographic or clinical factors were associated with reporting of childhood trauma. The prevalence of childhood trauma was ascertained using both the Childhood Trauma Questionnaire (CTQ) and a lifetime retrospective clinical note review in 129 individuals attending a general adult mental health service. Individuals were evaluated for the presence of mental health disorders, impulsivity, symptom severity and disability. Using the CTQ, childhood trauma was noted in 77% of individuals and recorded in 38% of individual's clinical notes (p<0.001). The greatest differences between CTQ reporting and clinical note documentation were noted for emotional neglect (62% versus 13.2%), physical neglect (48.1% versus 5.4%) and CSA (24.8% versus 8.5%). Childhood trauma was associated with increased psychopathology and greater symptom severity, and was particularly prevalent for individuals with personality disorders. This study demonstrated high rates of childhood trauma amongst adults attending a general adult mental health service. Furthermore, we demonstrated high rates of either non-enquiry from mental health professionals and/or high rates of non-documentation of childhood trauma by mental health professionals. Given the disparity between reporting of childhood trauma in clinical notes and findings with the CTQ, the use of a standardised questionnaire for the assessment of childhood trauma should be considered when performing a comprehensive mental health history.

Objectives The current study investigates the moderating effect of perceived social support on associations between child maltreatment severity and adult trauma symptoms. We extend the existing literature by examining the roles of severity of multiple maltreatment types (i.e., sexual, physical, and emotional abuse; physical and emotional neglect) and gender in this process. Methods The sample included 372 newlywed individuals recruited from marriage license records. Participants completed a number of self-report questionnaires measuring the nature and severity of child maltreatment history, perceived social support from friends and family, and trauma-related symptoms. These questionnaires were part of a larger study, investigating marital and intrapersonal functioning. We conducted separate, two-step hierarchical multiple regression models for perceived social support from family and perceived social support from friends. In each of these models, total trauma symptomatology was predicted from each child maltreatment severity variable, perceived social support, and the product of the two variables. In order to examine the role of gender, we conducted separate analyses for women and men. Results As hypothesized, increased severity of several maltreatment types (sexual abuse, emotional abuse, emotional neglect, and physical neglect) predicted greater trauma symptoms for both women and men, and increased physical abuse severity predicted greater trauma symptoms for women. Perceived social support from both family and friends predicted lower trauma symptoms across all levels of maltreatment for men. For women, greater perceived social support from friends, but not from family, predicted decreased trauma symptoms. Finally, among women, perceived social support from family interacted with child maltreatment such that, as the severity of maltreatment (physical and emotional abuse, emotional neglect) increased, the buffering effect of perceived social support from family on

Background The objective of this study is to investigate the association between childhood trauma and lipid profiles in adults from a highly traumatized population at-risk for cardiovascular disease. Method We recruited 452 participants, primarily African American, low socioeconomic status from general medical clinics in a large urban hospital. We performed direct comparisons, univariate ANOVA and regression analyses together and separated by sex, examining the associations of child abuse, BMI, lipid lowering drug use, blood pressure, age, and substance use to HDL levels and HDL/LDL ratios. Results A history of moderate to severe levels of childhood trauma and abuse was associated with a significant decrease in HDL levels (p≤0.01) and HDL/LDL ratios (p≤0.001) relative to males with low levels of abuse. This relationship held when the status of lipid-lowering drugs was considered. When controlling for age, substance abuse, tobacco use, and adult trauma, the effects of childhood trauma remained significant. We found a significant child abuse by sex interaction on HDL/LDL ratios (F(1, 369)=13.0, p≤0.0005) consistent with a differential effect of trauma on dyslipidemia in male but not female subjects Conclusions Our data suggest that childhood trauma exposure, obtained with self-report measures, may contribute to increased risk of cardiovascular disease by way of stress-mediated alterations of lipid concentration and composition in male, but not female, subjects.

Traumatic brain and spine injury (TBI/TSI) is a leading cause of death and lifelong disability in children. The biomechanical properties of the child's brain, skull, and spine, the size of the child, the age-specific activity pattern, and variance in trauma mechanisms result in a wide range of age-specific traumas and patterns of brain and spine injuries. A detailed knowledge about the various types of primary and secondary pediatric head and spine injuries is essential to better identify and understand pediatric TBI/TSI, which enhances sensitivity and specificity of diagnosis, will guide therapy, and may give important information about the prognosis. The purposes of this chapter are to: (1) discuss the unique epidemiology, mechanisms, and characteristics of TBI/TSI in children; (2) review the anatomic and functional imaging techniques that can be used to study common and rare pediatric TBI/TSI and their complications; (3) comprehensively review frequent primary and secondary brain injuries; and (4) to give a short overview of two special types of pediatric TBI/TSI: birth-related and nonaccidental injuries.

Introduction Significant deaths of between 21% and 38% occur from non-trauma surgical conditions in the accident and emergency room. Access to emergency surgical care is limited in many developing countries including Nigeria. We aimed to study the spectrum of non-trauma surgical emergencies, identify challenges in management and evaluate outcomes. Methods A one year prospective cohort study of all non-trauma emergencies in adults seen at the surgical emergency room of LASUTH from 1st October, 2011 to 30th September, 2012 was conducted. Data was analyzed using SPSS version 15.0. Results Of a total of 7536 patients seen, there were 7122 adults. Those with non-trauma conditions were 2065 representing 29% of adult emergencies. Age ranged between 15 and 97 years and male to female ratio was 1.7:1. Acute abdomen (30%), urological problems (18%) and malignancies (10%) were the most common. Among 985 patients requiring admission only 464 (47%) were admitted while the remaining 53% were referred to other centers. Emergency surgical intervention was carried out in 222 patients representing 48% of admitted patients. There were 12 (24%) non-trauma deaths in the emergency room. They were due to acute abdomen and malignancies in half of the cases. Conclusion Facilities for patients needing emergency care were inadequate with more than half of those requiring admission referred. Attention should be paid to the provision of emergency surgical services to the teeming number of patients seen on yearly basis in the Teaching Hospital. PMID:26566434

Otolaryngologists are commonly called upon to emergently evaluate blunt trauma to the facial skeleton. These injuries are occasionally associated with serious trauma to the orbital contents. This manuscript reviews these orbital injuries by considering the pertinent eye anatomy and the extensive examination usually performed by an ophthalmologist. Anterior and posterior segment injuries along with specific trauma to the optic nerve will also be discussed.

Caffeine consumption increases the urinary excretion of calcium and other minerals. Factors that affect caffeine metabolism such as steroid hormones may modify this effect. The purpose of this study was to evaluate the influence of oral contraceptive (OC) use on the 4-h urinary excretion of calcium, phosphorus, magnesium, zinc, sodium, potassium and caffeine metabolites in response to a high caffeine dose given as coffee beverage. Adult women, 20-29 y, users (+OC, n = 15) and nonusers (-OC, n = 15) of oral contraceptives, with calcium intake approximately 500 mg/d, participated in two tests, caffeine load (5 mg/kg body weight) and no-caffeine control, in a randomized crossover design. The net increase (caffeine load corrected by no caffeine) in urinary excretion of most minerals was significantly higher in -OC than in +OC (P < 0.05), with the larger group difference for calcium (ninefold) followed by magnesium (twofold), zinc (onefold) and potassium (onefold). Net increases in urinary excretion of 1-methylurate and paraxanthine were about three- and fivefold higher, respectively, in -OC than in +OC (P < 0.05) whereas net increases in urinary excretion of 5-acetylamino-6-formylamino-3-methyluracil (AFMU) and 1,7-dimethylurate were over twofold higher in the +OC than in -OC (P < 0.05). Following the caffeine load, most urinary minerals showed negative correlation with urinary 1-methylurate in -OC (R = -0.78, P < 0.01), and with urinary AFMU and 1,7-dimethylurate in +OC (R = -0.84, P < 0.01). Oral contraceptives appear to limit the renal effect of caffeine on mineral excretion possibly by reducing paraxanthine excretion, the most active caffeine metabolite.

Exposure to chronic and traumatic stress has been associated with the dysregulation of crucial stress response systems. Acculturation has been associated with unique forms of chronic psychosocial stress. The purpose of this study was to examine the effects of exposure to early traumatic stress and acculturation on dysregulation of the cortisol awakening response (CAR) in Mexican-American adults. Salivary cortisol samples were collected at awakening and 30, 45, and 60 minutes thereafter, on two consecutive weekdays from 59, healthy Mexican American adult males (26) and females (33), ages 18-38 years. Participants were assessed for level of acculturation and exposure to early trauma. Data were analyzed using a mixed effects regression model with repeated measures at four time points. Mixed effects regression results indicated a significant Early Trauma x Time interaction (p=.0029) and a significant Acculturation x Time interaction (p=.0015), after controlling for age and sex. Subsequent analyses of the interaction of Trauma x Acculturation x Time showed that more than minimal exposure to either risk factor was associated with attenuation of the awakening cortisol response (p=.0002). Higher levels of acculturation with greater Anglo-orientation were associated with attenuation of the CAR in Mexican-American adults. Both moderate and higher levels of exposure to early trauma were associated with an attenuated CAR. However, greater exposure to both risk factors was only incrementally worse than exposure to either one. PMID:20600049

Background Therapists who work with trauma clients are impacted both positively and negatively. However, most studies have tended to focus on the negative impact of the work, the quantitative evidence has been inconsistent, and the research has primarily been conducted outside the United Kingdom. Objectives This study aimed to assess the prevalence of, and identify predictor variables for, compassion satisfaction, burnout, and secondary traumatic stress in a group of UK therapists (N=253) working with adult trauma clients. Method An online questionnaire was developed which used The Professional Quality of Life Scale (Version 5) to assess compassion satisfaction, burnout, and secondary traumatic stress and collect demographics and other pertinent information. Results Whilst the majority of therapists scored within the average range for compassion satisfaction and burnout, 70% of scores indicated that therapists were at high risk of secondary traumatic stress. Maturity, time spent engaging in research and development activities, a higher perceived supportiveness of management, and supervision predicted higher potential for compassion satisfaction. Youth and a lower perceived supportiveness of management predicted higher risk of burnout. A higher risk of secondary traumatic stress was predicted in therapists engaging in more individual supervision and self-care activities, as well as those who had a personal trauma history. Conclusions UK therapists working with trauma clients are at high risk of being negatively impacted by their work, obtaining scores which suggest a risk of developing secondary traumatic stress. Of particular note was that exposure to trauma stories did not significantly predict secondary traumatic stress scores as suggested by theory. However, the negative impact of working with trauma clients was balanced by the potential for a positive outcome from trauma work as a majority indicated an average potential for compassion satisfaction.

Objective We tested a conceptual model of the effect of war-trauma exposure in childhood on psychological distress in young adulthood. Method Participants included 151 urban Kuwaiti children (51% female; M age = 10.62 years) exposed to the 1990-1991 Gulf crisis (assessed in 1993); participants also included 140 parents (81% female; M age mothers = 36.50 years; M age fathers = 41 years). In 2003, 120 participants were reassessed as young adults (50% female; M age = 21.19 years). Results The conceptual model was evaluated with structural equations. War-trauma exposure was associated with psychological distress in children and parents, but parents reported larger effects than children. Parents’ psychological distress did not contribute to children’s psychological distress. Children’s psychological distress did not dissipate over time. Social support may function as a potential mediator of the effect of war-trauma exposure on psychological distress. Conclusions Findings support the importance of early detection and treatment of children exposed to war-trauma. Findings also implicate social support as a factor to consider in clinical interventions for children exposed to war-trauma. PMID:23978198

Limited research has addressed factors associated with psychological distress following disasters among non-Western populations. The 2004 tsunami affected 1.7 million people across South Asia and Africa, with considerable variations in trauma-related outcomes. Pretraumatic and peritraumatic conditions associated with trauma-related symptoms in 305 Sri Lankan adult survivors (28% male, aged 18-83 years; mean = 39.9 years; standard deviation = 15.3), clinically assessed 1 month posttsunami, were evaluated retrospectively. Outcome measures were total scores on 11 trauma-related symptoms. Multivariate linear regression analyses tested for associations between pretraumatic and peritraumatic conditions and symptom scores, with peritraumatic conditions adjusted for pretraumatic variables. Pretraumatic conditions of female gender, employment, prior health and social issues, and substance use and peritraumatic conditions of loss of family, witnessing the tsunami, or suffering an injury were associated with trauma-related symptoms. The findings facilitate understanding cultural contexts that define risk factors associated with trauma-related symptoms in Sri Lankans, which are critical for developing culturally appropriate interventions.

Blunt traumatic abdominal wall disruptions associated with evisceration are very rare. The authors describe a case of traumatic abdominal wall disruption with bowel evisceration that occurred after a middle-aged woman sustained direct focal blunt force impact to the lower abdomen. Abdominal exploration and surgical repair of the abdominal wall defect were performed, with good clinical outcome. A brief overview of literature pertinent to this rare trauma scenario is presented.

Individuals with intellectual and developmental disabilities (IDD) are at risk for low-trauma fractures. We investigated the rate of low-trauma fractures and the odds of BMD testing in adults with/without IDD. Adults with IDD were more likely to have a low-trauma fracture, but there was no difference in bone mineral density (BMD) testing rates.

Background There is increasing evidence that a history of childhood abuse and neglect is not uncommon among individuals who experience mental disorder and that childhood trauma experiences are associated with adult psychopathology. Although several interview and self-report instruments for retrospective trauma assessment have been developed, many focus on sexual abuse (SexAb) rather than on multiple types of trauma or adversity. Methods Within the European Prediction of Psychosis Study, the Trauma and Distress Scale (TADS) was developed as a new self-report assessment of multiple types of childhood trauma and distressing experiences. The TADS includes 43 items and, following previous measures including the Childhood Trauma Questionnaire, focuses on five core domains: emotional neglect (EmoNeg), emotional abuse (EmoAb), physical neglect (PhyNeg), physical abuse (PhyAb), and SexAb. This study explores the psychometric properties of the TADS (internal consistency and concurrent validity) in 692 participants drawn from the general population who completed a mailed questionnaire, including the TADS, a depression self-report and questions on help-seeking for mental health problems. Inter-method reliability was examined in a random sample of 100 responders who were reassessed in telephone interviews. Results After minor revisions of PhyNeg and PhyAb, internal consistencies were good for TADS totals and the domain raw score sums. Intra-class coefficients for TADS total score and the five revised core domains were all good to excellent when compared to the interviewed TADS as a gold standard. In the concurrent validity analyses, the total TADS and its all core domains were significantly associated with depression and help-seeking for mental problems as proxy measures for traumatisation. In addition, robust cutoffs for the total TADS and its domains were calculated. Conclusions Our results suggest the TADS as a valid, reliable, and clinically useful instrument for assessing

The present investigation examined the interactive effect of cigarette smoking status (i.e., regular smoking versus non-smoking) and weekly exercise (i.e., weekly metabolic equivalent) in terms of posttraumatic stress (PTSD) symptom severity among a community sample of trauma-exposed adults. Participants included 86 trauma-exposed adults (58.1% female; Mage = 24.3). Approximately 59.7% of participants reported regular (≥ 10 cigarettes per day) daily smoking over the past year. The interactive effect of smoking status by weekly exercise was significantly associated with hyperarousal and avoidance symptom cluster severity (p ≤ .05). These effects were evident above and beyond number of trauma types and gender, as well as the respective main effects of smoking status and weekly exercise. Follow-up tests indicated support for the moderating role of exercise on the association between smoking and PTSD symptoms, such that the highest levels of PTSD symptoms were observed among regular smokers reporting low weekly exercise levels. Theoretical and clinical implications of the findings are discussed. PMID:24273598

Previous research has identified several individual-level factors that modify the risk of childhood trauma on adult psychiatric symptoms, including symptoms of major depression (MD) and posttraumatic stress (PTS). Neighborhood-level factors also influence the impact of individual-level exposures on adult psychopathology. However, no prior studies to our knowledge have explored cross-level interactions between childhood trauma and neighborhood-level factors on MD and PTS symptoms. The purpose of this study was therefore to explore cross-level interactions between a neighborhood-level factor – neighborhood-level crime – and childhood trauma on MD and PTS symptoms. Participants in this study (N = 3,192) were recruited from a large public hospital, and completed self-report inventories of childhood trauma and MD and PTS symptoms. Participant addresses were mapped onto 2010 census tracts, and data on crime within each tract was collected. Multilevel models found a significant cross-level interaction between childhood trauma and neighborhood crime on MD symptoms, such that the influence of high levels of childhood trauma on MD symptoms was enhanced for participants living in high-crime neighborhoods. Supplementary analyses found variation in the strength of cross-level interaction terms by types of childhood trauma and crime, with the strongest associations including emotional neglect paired with personal and property crime. The results provide preliminary support for interventions that help childhood trauma survivors find housing in less vulnerable neighborhoods and build skills to cope with neighborhood crime.

Abstract Individuals 65 years of age and over have the highest rates of traumatic brain injury (TBI)-related hospitalizations and deaths, and older adults (defined variably across studies) have particularly poor outcomes after TBI. The factors predicting these outcomes remain poorly understood, and age-specific care guidelines for TBI do not exist. This study provides an overview of TBI in older adults using data from the National Trauma Data Bank (NTDB) gathered between 2007 and 2010, evaluates age group-specific trends in rates of TBI over time using U.S. Census data, and examines whether routinely collected information is able to predict hospital discharge status among older adults with TBI in the NTDB. Results showed a 20–25% increase in trauma center admissions for TBI among the oldest age groups (those >=75 years), relative to the general population, between 2007 and 2010. Older adults (>=65 years) with TBI tended to be white females who have incurred an injury from a fall resulting in a “severe” Abbreviated Injury Scale (AIS) score of the head. Older adults had more in-hospital procedures, such as neuroimaging and neurosurgery, tended to experience longer hospital stays, and were more likely to require continued medical care than younger adults. Older age, injury severity, and hypotension increased the odds of in-hospital death. The public health burden of TBI among older adults will likely increase as the Baby Boom generation ages. Improved primary and secondary prevention of TBI in this cohort is needed. PMID:23962046

Selective nonoperative management is appropriate for most blunt splenic injuries in adults and children, but the efficacy of this approach is unknown when injury occurs in patients with concurrent infectious mononucleosis. We have reviewed our experience during the past 23 years with the selective nonoperative management of blunt splenic injury in these patients. Medical record review identified nine patients with blunt splenic injury and infectious mononucleosis from 1978 to 2001, representing 3.3 per cent of our total trauma population with blunt splenic injury treated during that interval. Two patients underwent immediate splenectomy because of hemodynamic instability. Seven patients were admitted with the intent to treat nonoperatively. Five patients were successfully managed nonoperatively. Two patients failed nonoperative management and underwent splenectomy, one because of hemodynamic instability and one because of an infected splenic hematoma. Concurrent infectious mononucleosis does not preclude the successful nonoperative management of blunt splenic injury. This small subset of patients may be managed nonoperatively using the same criteria as for patients whose splenic injuries are not complicated by infectious mononucleosis.

A cross-sectional study of the association between severity of childhood trauma and adult prostitution behaviors was conducted among 676 heterosexual drug addicts in San Antonio, Texas. Three hundred and fifty eight women and 338 men taking part in a national multisite program for AIDS prevention research completed the Childhood Trauma Questionnaire as part of a comprehensive risk behavior assessment. Women addicts in the sample were less educated, more likely to be in a common-law relationship, living with someone of the opposite sex or separated, and had lower incomes in comparison to men addicts. Among male subjects,higher educational levels and older age were positively associated with prostitution activities. Single female subjects were three times more likely to engage in selling sex than married subjects. Single women with higher incomes were more likely to be prostituting than single women with lower incomes. Black women reporting severe degrees of emotional abuse, emotional neglect, or physical neglect were more likely to engage in prostitution behavior than Hispanic or white women with similar levels of trauma. Black men with a history of childhood physical abuse were more likely to use prostitutes than Hispanic or white men.

Hypothalamic pituitary adrenal (HPA) axis and subjective stress response to a cold-water immersion task, the cold pressor task (CPT), in individuals (N=89) with post-traumatic stress disorder (PTSD) were examined. All tests were conducted at 08:00h after an overnight hospital stay. Plasma adrenocorticotrophin hormone (ACTH), cortisol, and subjective stress were examined at baseline and five post-task time points in controls (n=31), subjects with PTSD as a result of an index trauma during childhood (i.e. before age 18; n=25), and subjects with PTSD as a result of an index trauma as an adult (n=33). Approximately, 50% of individuals in both trauma groups were alcohol dependent, and the impact of this comorbidity was also examined. Subjects with PTSD, regardless of age of index trauma, had a less robust ACTH response as compared to controls. Regardless of the presence or absence of comorbid alcohol dependence, subjects with childhood trauma had lower cortisol at baseline and at all post-task measurement points and did not demonstrate the decrease in cortisol over the course of the 2h monitoring period seen in subjects with adult index trauma and controls. The findings reveal differences in the neuroendocrine response to the CPT in individuals with PTSD compared to control subjects, and differences in PTSD subjects when examined by age of index trauma.

The occurrence of sleep paralysis (SP) absent narcolepsy appears to not be uncommon in African Americans and probably other non-European groups. Prior research has linked SP to trauma and psychiatric disorders and suggested a specific relationship to panic disorder in African Americans. The objective of our study was to evaluate relationships of SP with trauma, concurrent psychiatric symptoms and lifetime psychiatric diagnoses in an adult African American population recruited from primary care. Cross sectional study with surveys and diagnostic interviews; Patients attending primary care clinics filled out a survey that determined the 6 month prevalence and associated features of SP, a panic disorder screen, the self-rated Hamilton Depression Scale, and an inventory of trauma exposure. A subset of trauma-exposed participants (N = 142) received comprehensive diagnostic interviews that incorporated the Structured Clinical Interview for DSM-IV and the Clinician Assessed PTSD Scale. Four hundred and forty-one adults participated (mean age-40.0 SD = 13.3, 68% female, 95% African American). Fourteen percent endorsed recent SP. In approximately 1/3 of those with SP, episodes also featured panic symptoms. SP was strongly associated with trauma history, and concurrent anxiety and mood symptoms. SP was not associated with specific psychiatric disorders other than lifetime (but not current) alcohol or substance use disorders. Our findings suggest that SP is not uncommon in adult African Americans and is associated with trauma and concurrent distress but not with a specific psychiatric diagnosis.

Insurance coverage has increased among young adults as a result of the Affordable Care Act (ACA) provision that allows young adults to remain covered under their parents' plans until age twenty-six. However, little is known about the provision's effects on the clinical outcomes and insurance coverage of patients with trauma--the most frequent cause of death and physical disability among young adults. Using 2007-12 data from the National Trauma Data Bank, we conducted a difference-in-differences analysis of coverage rates among trauma patients ages 19-25 (compared to patients ages 26-34, who served as the control group), and we examined trauma-relevant outcomes by patient, injury, and hospital characteristics. We found a 3.4-percentage-point decrease in uninsurance status among younger trauma patients following the policy change. The decrease was concentrated among men, non-Hispanic whites, those with relatively less severe injuries, and those who presented to nonteaching hospitals. We did not detect significant changes in the use of intensive care or in overall mortality. The heterogeneous coverage impact of the ACA dependent coverage provision on high- versus low-risk trauma patients has implications for future efforts to expand coverage.

The purpose of the present study was to examine the prevalence of child maltreatment and lifetime exposure to other traumatic events in a sample of deaf and hard of hearing (DHH; n=147) and matched hearing (H; n=317) college students. Participants completed measures of child maltreatment (CM), adult victimization and trauma exposure, and current symptoms of posttraumatic stress disorder (PTSD). Overall, DHH participants reported significantly more instances of CM compared to H participants, with 76% of DHH reporting some type of childhood abuse or neglect. Additionally, DHH participants reported experiencing a higher number of different types of CM, and also reported increased incidents of lifetime trauma exposure and elevated PTSD symptoms. Severity of deafness increased the risk of maltreatment, with deaf participants reporting more instances of CM than hard of hearing participants, and hard of hearing participants reporting more instances of CM than H participants. Among DHH participants, having a deaf sibling was associated with reduced risk for victimization, and identification with the Deaf community was associated with fewer current symptoms of PTSD. A regression model including measures of childhood physical and sexual abuse significantly predicted adult re-victimization and accounted for 27% of the variance among DHH participants. DHH participants report significantly higher rates of CM, lifetime trauma, and PTSD symptoms compared to H participants. Severity of deafness appears to increase the risk of being victimized. Being part of the Deaf community and having access to others who are deaf appear to be important protective factors for psychological well-being among DHH individuals.

Art therapy has often been applied in the treatment of traumatized adults, and good results in clinical practice have been reported. However, although art therapy experts underline these benefits, the effectiveness of art therapy in trauma treatment has not been established by systematic review. The aim of this systematic review is to identify and evaluate empirical evidence of the effectiveness of art therapy for trauma treatment. As a result of the systematic review, six controlled, comparative studies on art therapy for trauma in adult patients were found. In half of the included studies, a significant decrease in psychological trauma symptoms was found in the treatment groups, and one study reported a significant decrease in depression. Although there are limitations in the number of included studies, the number of participants, the heterogeneity of included studies, and their methodological quality, the results contribute to insight into the effectiveness of art therapy in trauma treatment and form an evidence base for the urgent need for further research on art therapy and trauma treatment.

The effect of childhood trauma, psychiatric diagnoses, and mental health services on school dropout among U.S. born and immigrant youth is examined using data from the Collaborative Psychiatric Epidemiology Surveys (CPES), a nationally representative probability sample of African Americans, Afro-Caribbeans, Asians, Latinos, and non-Latino Whites, including 2532 young adults, ages 21 to 29. The dropout prevalence rate was 16% overall, with variation by childhood trauma, childhood psychiatric diagnosis, race/ethnicity, and nativity. Childhood substance and conduct disorders mediated the relationship between trauma and school dropout. Likelihood of dropout was decreased for Asians, and increased for African Americans and Latinos, compared to non-Latino Whites as a function of psychiatric disorders and trauma. Timing of U.S. immigration during adolescence increased risk of dropout. PMID:21410919

This study's objective was to identify clinical characteristics of patients with a blunt traumatic injury that increased the risk of peritoneal or pericardial fluid collections and abdominal organ injuries not identified by a bedside focused abdominal sonogram for trauma (FAST) examination. This observational study used a retrospective chart review of a cohort of patients identified through a query of the University of Nebraska Medical Center's trauma registry, a tertiary referral center for portions of Nebraska, Iowa, and Missouri. Adult patients presenting to the Emergency Department (ED) for an evaluation of blunt traumatic injury from September 1996 to December 2002 were eligible if their ED course included admission to the trauma service after completion of a bedside FAST examination (US) and a confirmatory study (Conf) such as an abdominopelvic computed tomography scan or exploratory laparotomy within 12 h of completion of the ED FAST examination. The medical records of those patients with a US+/Conf+ or US-/Conf+ examination were reviewed. Clinical characteristics were recorded on a standard data collection form. Statistically significant predictors of a US-/Conf+ examination were found using a stepwise logistic regression procedure. A query of the trauma registry for the study period revealed 1453 adult individuals with blunt abdominal trauma, with 458 patients meeting the inclusion criteria. The clinical characteristics of the 79 US+/Conf+ examinations were compared to those of the 53 US-/Conf+ examinations. The presence of a radiographically proven pelvic fracture (odds ratio 3.459; 95% confidence interval of 1.308-9.157) and a radiographically or operatively proven renal injury (odds ratio 3.667; 95% confidence interval of 1.013-13.275) were found to be significant predictors. The presence of a pelvic fracture or renal injury in adult victims of blunt abdominal trauma increases the likelihood of a US-/Conf+ examination. Patients with a negative FAST

Objectives. We assessed sexual orientation disparities in exposure to violence and other potentially traumatic events and onset of posttraumatic stress disorder (PTSD) in a representative US sample. Methods. We used data from 34 653 noninstitutionalized adult US residents from the 2004 to 2005 wave of the National Epidemiologic Survey on Alcohol and Related Conditions. Results. Lesbians and gay men, bisexuals, and heterosexuals who reported any same-sex sexual partners over their lifetime had greater risk of childhood maltreatment, interpersonal violence, trauma to a close friend or relative, and unexpected death of someone close than did heterosexuals with no same-sex attractions or partners. Risk of onset of PTSD was higher among lesbians and gays (adjusted odds ratio [AOR] = 2.03; 95% confidence interval [CI] = 1.34, 3.06), bisexuals (AOR = 2.13; 95% CI = 1.38, 3.29), and heterosexuals with any same-sex partners (AOR = 2.06; 95% CI = 1.54, 2.74) than it was among the heterosexual reference group. This higher risk was largely accounted for by sexual orientation minorities’ greater exposure to violence, exposure to more potentially traumatic events, and earlier age of trauma exposure. Conclusions. Profound sexual orientation disparities exist in risk of PTSD and in violence exposure, beginning in childhood. Our findings suggest there is an urgent need for public health interventions aimed at preventing violence against individuals with minority sexual orientations and providing follow-up care to cope with the sequelae of violent victimization.

Adult dentoalveolar trauma most often occurs in the context of sports activities and traffic accidents. Coronal fractures are the most common type of lesion, followed by tooth luxation. We present the case of a 25-year-old woman who suffered alveolar bone damage and coronal fractures of the upper incisors, with extrusive luxation of the right central incisor, as the result of a fall. On the first visit, manual reduction of the buccal plate was carried out under local anesthesia, with repositioning of the right central incisor and splinting to the neighboring teeth. Composites were used to restore the coronal fractures. After one month, both upper central incisors and the right lateral incisor were subjected to endodontic treatment. Internal bleaching of the right lateral incisor was also carried out, due to pigmentation secondary to pulp necrosis. At follow-up 5 months later, the alveolar bone fracture was seen to have healed. Definitive anterior restorative treatment with porcelain veneers was therefore carried out. After two years the patient remains asymptomatic and in good dental condition. Key words:Dental trauma, extrusive luxation, dento-alveolar fracture, esthetic restoration. PMID:27957283

OBJECTIVE Sports-related traumatic brain injury (TBI) is an important public health concern estimated to affect 300,000 to 3.8 million people annually in the United States. Although injuries to professional athletes dominate the media, this group represents only a small proportion of the overall population. Here, the authors characterize the demographics of sports-related TBI in adults from a community-based trauma population and identify predictors of prolonged hospitalization and increased morbidity and mortality rates. METHODS Utilizing the National Sample Program of the National Trauma Data Bank (NTDB), the authors retrospectively analyzed sports-related TBI data from adults (age ≥ 18 years) across 5 sporting categories-fall or interpersonal contact (FIC), roller sports, skiing/snowboarding, equestrian sports, and aquatic sports. Multivariable regression analysis was used to identify predictors of prolonged hospital length of stay (LOS), medical complications, inpatient mortality rates, and hospital discharge disposition. Statistical significance was assessed at α < 0.05, and the Bonferroni correction for multiple comparisons was applied for each outcome analysis. RESULTS From 2003 to 2012, in total, 4788 adult sports-related TBIs were documented in the NTDB, which represented 18,310 incidents nationally. Equestrian sports were the greatest contributors to sports-related TBI (45.2%). Mild TBI represented nearly 86% of injuries overall. Mean (± SEM) LOSs in the hospital or intensive care unit (ICU) were 4.25 ± 0.09 days and 1.60 ± 0.06 days, respectively. The mortality rate was 3.0% across all patients, but was statistically higher in TBI from roller sports (4.1%) and aquatic sports (7.7%). Age, hypotension on admission to the emergency department (ED), and the severity of head and extracranial injuries were statistically significant predictors of prolonged hospital and ICU LOSs, medical complications, failure to discharge to home, and death.

Emotional mental imagery occurs across anxiety disorders, yet is neglected in bipolar disorder despite high anxiety comorbidity. Furthermore, a heightened susceptibility to developing intrusive mental images of stressful events in bipolar disorder and people vulnerable to it (with hypomanic experience) has been suggested. The current study assessed, prospectively, whether significant hypomanic experience (contrasting groups scoring high vs. low on the Mood Disorder Questionnaire, MDQ) places individuals at increased risk of visual reexperiencing after experimental stress. A total of 110 young adults watched a trauma film and recorded film-related intrusive images for 6 days. Compared to the low MDQ group, the high MDQ group experienced approximately twice as many intrusive images, substantiated by convergent measures. Findings suggest hypomanic experience is associated with developing more frequent intrusive imagery of a stressor. Because mental imagery powerfully affects emotion, such imagery may contribute to bipolar mood instability and offer a cognitive treatment target. PMID:25419498

Disrupted social behavior is a core symptom of multiple psychiatric and neurodevelopmental disorders. Many of these disorders are exacerbated by adverse infant experiences, including maltreatment and abuse, which negatively affect amygdala development. Although a link between impaired social behavior, abnormal amygdala function and depressive-like behavior following early adversity has been demonstrated in humans and animal models, the developmental emergence of maltreatment-related social deficits and associated amygdala neural activity are unknown. We used a naturalistic rodent model of maternal maltreatment during a sensitive period, postnatal days 8-12 (PN8-12), which produces social behavior deficits that precede adolescent depressive-like behavior and amygdala dysfunction, to examine social behavior in infancy, periweaning and adolescence. Neural activity in response to the social behavior test was assessed via c-Fos immunohistochemistry at these ages. A separate group of animals was tested for adult depressive-like behavior in the forced swim test. Maltreatment spared infant (PN16-18) social behavior but disrupted periweaning (PN20-22) and adolescent (PN42-48) social behavior. Maltreated rats exhibited blunted neural activation in the amygdala and other areas implicated in social functioning, including the medial prefrontal cortex and nucleus accumbens, at these ages and increased adult depressive-like behavior. These findings may suggest corticolimbic involvement in the emergence of maltreatment-induced social deficits that are linked to adult depressive-like behavior, thereby highlighting potential targets for therapeutic intervention. Understanding how infant experiences influence social behavior and age-specific expression across development may provide insights into basic neural mechanisms of social behaviors and disease-relevant social dysfunction exacerbated by early-life stress.

Diaphragmatic injury is an uncommon but clinically important entity in the setting of trauma. Computed tomography (CT) is widely used to evaluate hemodynamically stable trauma patients. While prior studies have identified CT signs of diaphragm injury in blunt or penetrating trauma, no study has directly compared signs across these two types of injuries. We identified patients with surgically proven diaphragm injuries who underwent CT at presentation. Three reviewers examined each for 12 signs of diaphragm injury, as well as for an overall impression of diaphragm injury. We reviewed a total of 84 patients (37 % blunt trauma, 63 % penetrating). The initial interpreting radiologists discovered 77 % of blunt and 47 % of penetrating injuries (p = 0.01). We found that the majority of signs of diaphragmatic injury were split between those common in blunt trauma and those common in penetrating trauma, with minimal overlap. The presence of at least one blunt injury sign has 90 % sensitivity for diaphragm injury in blunt trauma; the presence of a wound tract traversing the diaphragm has 92 % sensitivity in penetrating trauma. Inter-observer reliability of these signs is also high (κ > 0.65). Penetrating diaphragm injuries present a different spectrum of imaging findings from those in blunt trauma and are underdiagnosed at CT; looking for a wound tract traversing the diaphragm is highly sensitive for diaphragm injury in these cases. Signs of organ or diaphragm fragment displacement are sensitive for blunt diaphragm injuries, consistent with these injuries being caused by increased intra-abdominal pressure.

Children and adolescents who sustain a distal forearm fracture (DFF) owing to mild, but not moderate, trauma have reduced bone strength and cortical thinning at the distal radius and tibia. Whether these skeletal deficits track into adulthood is unknown. Therefore, we studied 75 women and 75 men (age range, 20 to 40 years) with a childhood (age < 18 years) DFF and 150 sex-matched controls with no history of fracture using high-resolution peripheral quantitative computed tomography (HRpQCT) to examine bone strength (ie, failure load) by micro-finite element (µFE) analysis, as well as cortical and trabecular bone parameters at the distal radius and tibia. Level of trauma (mild versus moderate) was assigned using a validated classification scheme, blind to imaging results. When compared to sex-matched, nonfracture controls, women and men with a mild trauma childhood DFF (eg, fall from standing height) had significant reductions in failure load (p < 0.05) of the distal radius, whereas women and men with a moderate trauma childhood DFF (eg, fall while riding a bicycle) had values similar to controls. Consistent findings were observed at the distal tibia. Furthermore, women and men with a mild trauma childhood DFF had significant deficits in distal radius cortical area (p < 0.05), and significantly lower dual-energy X-ray absorptiometry (DXA)-derived bone density at the radius, hip, and total body regions compared to controls (all p < 0.05). By contrast, women and men with a moderate trauma childhood DFF had bone density, structure, and strength that did not differ significantly from controls. These findings in young adults are consistent with our observations in children/adolescents with DFF, and they suggest that a mild trauma childhood DFF may presage suboptimal peak bone density, structure, and strength in young adulthood. Children and adolescents who suffer mild trauma DFFs may need to be targeted for lifestyle interventions to help achieve improved skeletal health.

Children and adolescents who suffer mild trauma DFFs may need to be targeted for lifestyle interventions to help achieve improved skeletal

Objective Multiple rib fractures (RFs) and pulmonary contusions (PCs), with resulting systemic lung inflammation, are the most common injuries caused by blunt chest trauma (BCT) in motor vehicle accidents. This study examined levels of the inflammation marker interleukin (IL)-6 and those of the acute-phase reactant surfactant protein (SP)-D in patients with BCT. Design Prospective, cross-sectional, observational study. Setting Single-centre, tertiary care hospital in the Black Sea Region of Turkey. Participants The study included 60 patients with BCT who were hospitalised in our thoracic surgery department. Parameters measures The SP-D and IL-6 serum levels of patients with RFs (two or more RFs) (n=30) and patients with PCs (n=30) were measured after 6 hours, 24 hours and 7 days, and compared with those of age-matched and gender-matched healthy participants. Results The 6-hour serum SP-D levels of the RFs (p=0.017) and PCs (p<0.001) groups were significantly higher than those of the healthy controls. The 24-hour and 7-day SP-D levels of both groups were also higher than the control group. The serum IL-6 levels of both groups were significantly higher than those of the control group. We have found Injury Severity Score to be independently related to 6-hour IL-6 (β=1.414, p<0.001) and 24-hour IL-6 levels (β=1.067, p<0.001). The development of complications was independently related to 6-hour SP-D level (β=0.211, p=0.047). Conclusions RFs and PCs after BCT lead to local and systemic inflammation due to lung injury. The levels of the systemic inflammation marker IL-6 and those of the acute-phase reactant SP-D were elevated in the present study. The SP-D level may be used as a marker in the follow-up of BCT-related complications. PMID:27733410

Every day nurses work in environments that expose them to trauma and they move through their professional space as embodied creatures with their own histories of trauma. Because trauma changes our bodies in multiple ways, these diverse, changed and changing embodied selves are the people who come to class when nurses engage in higher education.…

For any patient with obvious or suspected chest trauma, one must first assure an adequate airway and adequate ventilation. One should never hesitate to administer oxygen to a victim with a chest injury. The nurse should be concerned with adequate circulation--this may mean the administration of intravenous fluids, specifically volume expanders, via large-bore cannulae. Any obvious open chest wound should be sealed, and any fractures should be splinted. These patients should be rapidly transported to the nearest Emergency Department capable of handling this type of injury. The majority of patients who arrive in the Emergency Department following blunt or penetrating trauma should be considered to be in critical condition until proven otherwise. On presentation, it is essential to recognize those signs, symptoms, and laboratory values that identify the patient's condition as life-threatening. Simple recognition of these signs and symptoms and early appropriate intervention may alter an otherwise fatal outcome.

A 28-year-old man was brought to the emergency department for severe facial swelling the morning after a bungee jumping accident. The patient had been making jumps nearly every weekend for the past 3 years without injury. This time, he had performed a nighttime jump from a railroad trestle over the gorge of a small river. The height of the bridge at the center of the gorge was about 200 ft, and the river was about 12 ft deep. When the patient jumped, he hit the water face first, plunging under the surface to his waist. The cause of the accident was thought to be a miscalculation of the bridge height.

Pneumomediastinum is often an incidental finding following a blunt or penetrating trauma to the neck or chest. We report a rare case of pneumomediastinum following an isolated facial trauma that was diagnosed on imaging. We also review the clinical signs of this condition, its radiologic characteristics, and the 18 previously reported cases of pneumomediastinum following facial trauma.

Background Coronary artery dissection is a rare complication of blunt thoracic trauma which can become rapidly lethal necessitating prompt diagnosis and treatment. Most reported cases of coronary artery injury, including dissection, involve the left anterior descending coronary artery, given its anatomical location in relation to the impact. Description of case A 72-year-old male, who was involved in a vehicular accident, sustained blunt thoracic trauma which resulted in isolated right coronary artery dissection and acute myocardial infarction. The culprit lesion was found in coronary angiography in the proximal right coronary artery and was successfully repaired with percutaneous coronary intervention and one drug-eluting stent placement. Conclusion Traumatic dissection of coronary arteries must be suspected in blunt thoracic trauma. It can be treated with interventional management and results in a fairly good prognosis.

INTRODUCTION Blunt esophageal injury is extremely rare event. However, it is a potential morbid injury unless managed early. PRESENTATION OF CASE We report a rare case of blunt esophageal injury for a 28-year old male who presented with history of fall of heavy object over the right side of the chest. Diagnostic work up including chest X-ray, computerized tomography scans and gastrografin esophagogram revealed lower esophageal rupture. Right mini-thoracotomy with esophageal repair was performed. Postoperative course was uneventful. DISCUSSION The exact mechanism of blunt esophageal injury remains uncertain. This report described a unique location of esophageal rupture after blunt trauma that happened on the right side. Diagnosis of esophageal injury needs high index of suspicion and accurate diagnostic workup. CONCLUSION Prompt diagnosis and management are the key for better prognosis in patients with blunt esophageal injury. PMID:24394856

Childhood adversity has been shown to increase the risk of psychotic symptoms in adult life. However, there are no previous studies looking at the association between experiencing a natural disaster during childhood and the development of psychotic symptoms in young adulthood. Eight hundred and six bushfire-exposed children and 725 control children were evaluated following the 1983 South Australian bushfires. Five hundred and twenty nine (65.6%) of the bushfire group and 464 (64%) controls participated in a follow up study 20 years later. Childhood data on emotional and behavioural disorders and dysfunctional parenting was available. The adult assessment included the Australian National Health and Well-Being psychosis screen and detailed information about trauma, childhood adversity and alcohol and cannabis abuse. 5.6% of subjects responded positively to the psychosis screen and 2.6% responded positively to a further probe question. Psychotic symptoms were more common in subjects exposed to a greater number of traumas, and were associated with higher rates of childhood adversity, emotional and behavioural disturbance, dysfunctional parenting, and alcohol and cannabis abuse. Subjects exposed to bushfires as children did not have a greater risk of psychosis. Our results indicate that exposure to multiple traumas, rather than a single major trauma, increases the risk of later psychosis.

Background Blunt cardiac injury is a rare trauma entity. Here, we sought to evaluate the relevance and prognostic significance of blunt cardiac injury in severely injured patients. Methods In a retrospective multicentre study, using data collected from 47,580 patients enrolled to TraumaRegister DGU (1993-2009), characteristics of trauma, prehospital / hospital trauma management, and outcome analysis were correlated to the severity of blunt cardiac injury. The severity of cardiac injury was assessed according to the abbreviated injury score (AIS score 1-6), the revised injury severity score (RISC) allowed comparison of expected outcome with injury severity-dependent outcome. N = 1.090 had blunt cardiac trauma (AIS 1-6) (2.3% of patients). Results Predictors of blunt cardiac injury could be identified. Sternal fractures indicate a high risk of the presence of blunt cardiac injury (AIS 0 [control]: 3.0%; AIS 1: 19.3%; AIS 2-6: 19.1%). The overall mortality rate was 13.9%, minor cardiac injury (AIS 1) and severe cardiac injury (AIS 2-6) are associated with higher rates. Severe blunt cardiac injury (AIS 4 and AIS 5-6) is associated with a higher mortality (OR 2.79 and 4.89, respectively) as compared to the predicted average mortality (OR 2.49) of the study collective. Conclusion Multiple injured patients with blunt cardiac trauma are at high risk to be underestimated. Careful evaluation of trauma patients is able to predict the presence of blunt cardiac injury. The severity of blunt cardiac injury needs to be stratified according to the AIS score, as the patients’ outcome is dependent on the severity of cardiac injury. PMID:26136126

Background The optimal timing of initiating low–molecular weight heparin (LMWH) in patients who have undergone nonoperative management (NOM) of blunt solid organ injuries (SOIs) remains controversial. We describe the safety of early initiation of chemical venous thromboembolism (VTE) prophylaxis among patients undergoing NOM of blunt SOIs. Methods We retrospectively studied severely injured adults who sustained blunt SOI without significant intracranial hemorrhage and underwent an initial NOM at a Canadian lead trauma hospital between 2010 and 2014. Safety was assessed based on failure of NOM, defined as the need for operative intervention, in patients who received early (< 48 h) or late LMWH (≥48 h, or early discharge [< 72 h] without LMWH). Results We included 162 patients in our analysis. Most were men (69%), and the average age was 42 ± 18 years. The median injury severity score was 17, and splenic injuries were most common (97 [60%], median grade 2), followed by liver (57 [35%], median grade 2) and kidney injuries (31 [19%], median grade 1). Combined injuries were present in 14% of patients. A total of 78 (48%) patients received early LMWH, while 84 (52%) received late LMWH. The groups differed only in percent of high-grade splenic injury (14% v. 32%). Overall 2% of patients failed NOM, none after receiving LMWH. Semielective angiography was performed in 23 (14%) patients. The overall rate of confirmed VTE on imaging was 1.9%. Conclusion Early initiation of medical thromboembolic prophylaxis appears safe in select patients with isolated SOI following blunt trauma. A prospective multicentre study is warranted. PMID:26820318

Blunt traumatic injury is one of the leading causes of morbidity and mortality in the United States. Unintentional injury represents the leading cause of death in the United States for all persons between the ages of 1 and 44 years. In the setting of blunt abdominal trauma, the reported rate of occurrence of bowel and mesenteric injuries ranges from 1% to 5%. Despite the relatively low rate of blunt bowel and mesenteric injury in patients with abdominal and pelvic trauma, delays in diagnosis are associated with increased rates of sepsis, a prolonged course in the intensive care unit, and increased mortality. During the past 2 decades, as multidetector computed tomography (CT) has emerged as an essential tool in emergency radiology, several direct and indirect imaging features have been identified that are associated with blunt bowel and mesenteric injury. The imaging findings in cases of blunt bowel and mesenteric injury can be subtle and may be seen in the setting of multiple complex injuries, such as multiple solid-organ injuries and spinal fractures. Familiarity with the various imaging features of blunt bowel and mesenteric injury, as well as an understanding of their clinical importance with regard to the care of the patient, is essential to making a timely diagnosis. Once radiologists are familiar with the spectrum of findings of blunt bowel and mesenteric injury, they will be able to make timely diagnoses that will lead to improved patient outcomes.

The purpose of this article was to review the empirical literature that investigated trauma and stress among older adults in the criminal justice system. Nineteen journal articles published between 1988 and 2010 were identified and extracted via research databases and included mixed age samples of adjudicated older and younger adults (n = 11) or older adult only samples (n = 8). Findings revealed past and current trauma and stress, consequences and/or correlates, and internal and external coping resources among aging offenders. The implications and future directions for gerontological social work, research, and policy with older adults in the criminal justice system are advanced.

Pelvic trauma accounts for only 3% of all skeletal injuries but may have mortality as high as 45% in cases of severe trauma. Significant high-grade-mechanism trauma to the pelvis must always take the abdomen into consideration for evaluation. The focused assessment with sonography for trauma (FAST) examination has been shown to be a valuable tool in assessing the unstable trauma patient with blunt abdominal injury, though its diagnostic utility is much less well-defined than in primary pelvic trauma. This systematic review explores the utility and limitations of the FAST examination in patients with blunt pelvic trauma and discusses the timing for the examination during the trauma survey. Newer techniques for emergency department management of the unstable trauma patient are also addressed.

Many trauma survivors seem to be reluctant to seek professional help. The aim of the current review was to synthesize relevant literature, and to systematically classify trauma survivors' perceived barriers and facilitators regarding mental health service utilization. The systematic search identified 19 studies addressing military personnel and 17 studies with trauma survivors of the general population. The data analysis revealed that the most prominent barriers included concerns related to stigma, shame and rejection, low mental health literacy, lack of knowledge and treatment-related doubts, fear of negative social consequences, limited resources, time, and expenses. Perceived facilitators lack attention in research, but can be influential in understanding mental health service use. Another prominent finding was that trauma survivors face specific trauma-related barriers to mental health service use, especially concerns about re-experiencing the traumatic events. Many trauma survivors avoid traumatic reminders and are therefore concerned about dealing with certain memories in treatment. These perceived barriers and facilitators were discussed regarding future research and practical implications in order to facilitate mental health service use among trauma survivors.

With increased awareness and liberal screening of trauma patients with identified risk factors, recent case series demonstrate improved early diagnosis of carotid artery trauma before they become problematio. There remains a need for unified screening criteria for both intracranial and extracranial carotid trauma. In the absence of contraindications, antithrombotic agents should be considered in blunt carotid artery injuries, as there is a significant risk of progression of vessel injury with observation alone. Despite CTA being used as a common screening modality, it appears to lack sufficient sensitivity. DSA remains to be the gold standard in screening. Endovascular techniques are becoming more widely accepted as the primary surgical modality in the treatment of blunt extracranial carotid injuries and penetrating/blunt intracranial carotid lessions. Nonetheless, open surgical approaches are still needed for the treatment of penetrating extracranial carotid injuries and in patients with unfavorable lesions for endovascular intervention.

An item-cuing directed forgetting task was used to investigate whether women reporting repressed (n = 13) or recovered (n = 13) memories of childhood sexual abuse (CSA) exhibit an avoidant encoding style (and resultant impaired memory) for trauma cues relative to women reporting no CSA experience (n = 15). All participants viewed intermixed trauma (e.g., molested), positive (e.g., confident), and categorized neutral (e.g., mailbox) words on a computer screen and were instructed either to remember or to forget each word. The results provided no support for the hypothesis that people reporting either repressed or recovered memories of CSA are especially adept at forgetting words related to trauma. These groups recalled words they were instructed to remember more often than words they were instructed to forget regardless of whether they were trauma related.

Previous studies have indicated that metal particles remain on bone after sharp force injury or gunshot and that their detection by scanning electron microscopy with energy dispersive X-ray spectrometry (SEM-EDS) could greatly help in tool identification. However, the presence of metal particles on bone surfaces in the context of blunt force trauma has never been assessed experimentally. For this reason the present paper represents an experimental study of the behaviour of metal residues on bone following blunt force injury. Ten fresh sub-adult bovine metatarsal bones were manually cleaned of soft tissues. They were then struck by metal bars (copper, iron or aluminium) on the external surface of the mid-diaphysis. All blunt metal instruments used in this study left a sign in the form of single particles, a smear or a powder-like deposit on the bone surface. The residues of all three metal implements were detected on the bone surface, 0.3-10 mm from the fracture border. The presence of metal particles was confirmed in all samples struck with iron and copper and in two of six aluminium samples; no particles were detected on the negative control. Chemical composition of residues highly corresponded with the composition of applied bars.

Objectives To evaluate ethnic group differences in the association between trauma exposure and health status among an ethnically diverse sample originating in Hawai‘i. Design Across a ten-year period (1998–2008), participants (N = 833) completed five waves of questionnaire assessments. Trauma exposure was measured retrospectively at the most recent assessment (wave 5), socioeconomic resources (educational attainment and employment status) were measured at wave 1, and self-rated health was measured at each of the five waves. Results Results indicated that greater exposure to trauma was associated with poorer self-rated health, as were lower educational attainment and lower work status. In addition there was ethnic group variation in health ratings, as well as in how strongly trauma exposure predicted health status. Specifically, within Filipino American and Native Hawaiian ethnic groups, there was a stronger negative association between trauma exposure and self-rated health. Conclusion These results suggest complex interrelations among trauma, ethnicity, socioeconomic status, and physical health. Further understanding these relations may have implications for medical and behavioral interventions in vulnerable populations. PMID:22732011

Many patients with bipolar disorder (BD) have difficulties in facial emotion recognition, which may also be impaired in maltreated children and in subjects who have a positive history of childhood traumatic experiences. Childhood trauma is reported with a high prevalence in BD and it is considered a risk factor for the disorder. As the relationship between facial emotion recognition and childhood trauma in BD has not yet been directly investigated, in this study we examined whether the presence of a childhood trauma in affectively stable BD patients was associated with poorer performance in emotion recognition. Seventy-five BD I and II participants completed the Childhood Trauma Questionnaire retrospectively assessing five types of childhood trauma (emotional, physical and sexual abuse, and emotional and physical neglect) and the Emotion Recognition Task evaluating the ability to correctly identify six basic facial emotions (happiness, sadness, anger, disgust, fear and surprise). Our results suggest that the presence of childhood trauma in participants with BD is associated with a more severe clinical presentation (earlier onset, longer duration of illness, and higher depressive symptom ratings) and that BD patients with a positive childhood history of emotional neglect perform worse than those without such a history in recognizing anger.

Introduction : The nonoperative management of traumatic spleen injuries is the modality of choice in patients with blunt abdominal trauma and hemodynamic stability. However, there are still questions about the treatment indication in some groups of patients, as well as its follow-up. Aim: Update knowledge about the spleen injury. Method : Was performed review of the literature on the nonoperative management of blunt injuries of the spleen in databases: Cochrane Library, Medline and SciELO. Were evaluated articles in English and Portuguese, between 1955 and 2014, using the headings "splenic injury, nonoperative management and blunt abdominal trauma". Results : Were selected 35 articles. Most of them were recommendation grade B and C. Conclusion : The spleen traumatic injuries are frequent and its nonoperative management is a worldwide trend. The available literature does not explain all aspects on treatment. The authors developed a systematization of care based on the best available scientific evidence to better treat this condition.

Blunt Cardiac Rupture (BCR) is a life threatening injury. Majority of patients do not reach the hospital and in those who reach the emergency department, timely diagnosis and treatment is a challenge. The case is about a patient with multiple blunt injuries who presented in shock. Cardiac tamponade was suspected on clinical grounds and on evidence of mediastinal widening on radiograph. In the absence of songography, the diagnosis was confirmed by subxiphoid pericardial window. Emergency thoracotomy revealed a right atrial appendage rupture which was surgically corrected. The patient also underwent splenectomy for grade IV splenic injury. Liver injury, pubic diastasis and tibial spine avulsion fracture was managed conservatively. He recovered well. Systematic observance of trauma resuscitation guidelines can help salvage patients with life threatening complex injuries even in the absence of specialized imaging investigations. PMID:28050441

We aimed to investigate the correlation between the Glasgow Coma Scale (GCS), the injury severity score (ISS) and serum levels of trace elements (TE) in severe trauma patients to analyze alteration of the levels of trace elements and serum biochemical indexes in the period of admission from 126 adult cases of severe brain trauma with traffic accidents. Multi-trace elements for patients in the trauma-TE groups were used. The results indicated that all patients presented an acute trace elements deficiency syndrome (ATEDs) after severe trauma, and the correlation between ISS and serum levels of Fe, Zn, and Mg was significant. Compared to the normal control group, levels of the trace elements in serum were significantly decreased after trauma, suggesting that enhancement of immunity to infection and multiple organ failure (MOF) via the monitoring and supplement of trace elements will be a good strategy to severe traumatic patients in clinics.

Psychologists have long assumed a connection between traumatic experience and psychological dissociation. This hypothesis is referred to as the trauma model of dissociation. In the past decade, a series of papers have been published that question this traditional causal link, proposing an alternative fantasy model of dissociation. In the present research, the relationship among dissociation, suggestibility, and fantasy proneness was examined. Suggestibility was measured through the Gudjonsson Scale of Interrogative Suggestibility (GSS) as well as an autobiographically based version of this measure based on the events of September 11, 2001. Consistent with prior research and with the trauma model, dissociation correlated positively with trauma severity (r = .32, p < .01) and fantasy proneness (r = .60, p < .01). Inconsistent with the fantasy model, dissociation did not correlate with the neutral form of the GSS and correlated negatively (r = -.24, p < .05) with the trauma-focused form of this suggestibility measure. Although some participants did become quite emotional during the procedure, the risk/benefit ratio was perceived by almost all participants to be positive, with more reactive individuals evaluating the procedure more positively. The results consistently support the trauma model of dissociation and fail to support the fantasy model of dissociation.

The purpose of the present research was to examine Deese-Roediger-McDermott (DRM) false memory for trauma-related and nontrauma-related lists in adolescents and adults with and without documented histories of child sexual abuse (CSA). Individual differences in psychopathology and adult attachment were also explored. Participants were administered free recall and recognition tests after hearing CSA, negative, neutral, and positive DRM lists. In free recall, CSA and negative lists produced the most false memory. In sharp contrast, for recognition, CSA lists enjoyed the highest d’ scores. CSA-group adolescents who evinced greater PTSD symptoms had higher rates of false memory compared to: 1) nonCSA-group adolescents with higher PTSD symptom scores (free recall), and 2) CSA-group adolescents with lower PTSD symptom scores (recognition). Regression analyses revealed that individuals with higher PTSD scores and greater fearful-avoidant attachment tendencies showed less proficient memory monitoring for CSA lists. Implications for trauma and memory development and for translational research are discussed. PMID:23786687

Current management of high-grade blunt renal trauma favors a nonoperative approach when possible. We performed a retrospective study of high grade blunt renal injuries at our level I trauma center to determine the indications and success of nonoperative management (NOM). 47 patients with blunt grade IV or V injuries were identified between October 2004 and December 2013. Immediate operative patients (IO) were compared to nonoperatively managed (NOM). Of the 47 patients, 3 (6.4%) were IO and 44 (95.6%) NOM. IO patients had a higher heart rate on admission, 133 versus 100 in NOM (P = 0.01). IO patients had a higher rate of injury to the renal vein or artery (100%) compared to NOM group (18%) (P = 0.01). NOM failed in 3 of 44 patients (6.8%). Two required nonemergent nephrectomy and one required emergent exploration resulting in nephrectomy. Six NOM patients had kidney-related complications (13.6%). The renal salvage rate for the entire cohort was 87.2% and 93.2% for NOM. Nonoperative management for hemodynamically stable patients with high-grade blunt renal trauma is safe with a low risk of complications. Management decisions should consider hemodynamic status and visualization of active renal bleeding as well as injury grade in determining operative management. PMID:28018427

Introduction Pancreatoduodenal (PD) injury is an uncommon but serious complication of blunt and penetrating trauma, associated with high mortality. The aim of this study was to assess the incidence, mechanisms of injury, initial operation rates and outcome of patients who sustained PD trauma in the UK from a large trauma registry, over the period 1989–2013. Methods The Trauma Audit and Research Network database was searched for details of any patient with blunt or penetrating trauma to the pancreas, duodenum or both. Results Of 356,534 trauma cases, 1,155 (0.32%) sustained PD trauma. The median patient age was 27 years for blunt trauma and 27.5 years for penetrating trauma. The male-to-female ratio was 2.5:1. Blunt trauma was the most common type of injury seen, with a ratio of blunt-to-penetrating PD injury ratio of 3.6:1. Road traffic collision was the most common mechanism of injury, accounting for 673 cases (58.3%). The median injury severity score (ISS) was 25 (IQR: 14–35) for blunt trauma and 14 (IQR: 9–18) for penetrating trauma. The mortality rate for blunt PD trauma was 17.6%; it was 12.2% for penetrating PD trauma. Variables predicting mortality after pancreatic trauma were increasing age, ISS, haemodynamic compromise and not having undergone an operation. Conclusions Isolated pancreatic injuries are uncommon; most coexist with other injuries. In the UK, a high proportion of cases are due to blunt trauma, which differs from US and South African series. Mortality is high in the UK but comparison with other surgical series is difficult because of selection bias in their datasets. PMID:25723689

We have previously shown that heart-shaped balloons have a different explosion mechanism than spherical balloons in which the former splits into two rubber parts still attached to the balloon base with a backward whiplash motion. This backward whiplash motion may cause significant blunt ocular trauma if the balloon is inflated by mouth. In this article, the energy of the blunt ocular trauma is estimated by the high speed camera photos analysis of the balloon burst. Furthermore, we describe the followup of eight patients with ocular trauma following inflation of heart-shaped balloons.

There is a great deal of research on the prevalence, correlates, and treatment of PTSD in the general population. However, we know very little about the manifestation and consequences of PTSD in more complicated patient populations. The purpose of the current paper is to provide a comprehensive review of PTSD within the context of severe mental illness (SMI; i.e., schizophrenia spectrum disorders, mood disorders). Extant data suggest that trauma and PTSD are highly prevalent among individuals with SMI relative to the general population, and both are associated with adverse clinical functioning and increased healthcare burden. However, trauma and PTSD remain overlooked in this population, with low recognition rates in public-sector settings. Additionally, there are few data on the clinical course and treatment of PTSD among individuals with SMI. Particularly lacking are longitudinal studies, randomized controlled treatment trials, and studies using ethno-racially diverse samples. Furthermore, there is a need to better understand the interplay between trauma, PTSD, and severe forms of mental illness and to further develop and disseminate evidence-based PTSD treatments in this population. The current state of the literature and future directions for practice are discussed. PMID:21596012

By 2050 it is anticipated that close to half (40%) of all trauma patients will be over the age of 65. Recovery post trauma for these individuals is more complicated than among younger individuals. Specifically there is an increased risk for: (1) functional decline; (2) higher mortality rates; (3) longer length of stay; (4) greater resource consumption; (5) nursing home placement; (6) adverse events such as infections, pressure ulcers and falls; and (7) rehospitalization post discharge. Early mobilization has been shown to improve outcomes. Unfortunately, there are many challenges to early mobilization. The Function Focused Care Intervention was developed to overcome these challenges. The purpose of this paper was to describe the initial recruitment of the first 25 participants and delineate the challenges and successes associated with implementation of this intervention. Overall the intervention was implemented as intended and recruitment rates were consistent with other studies. Most patients were female, white and on average 79 years of age. Optimizing physical activity of patients was a low priority for the nurses with patient safety taking precedence. Patients spent most of the time in bed. Age, depression and tethering were the only factors that were associated with physical activity and functional outcomes of patients. Ongoing work is needed to keep patients physically active in the immediate post trauma recovery period. PMID:26547682

Although previous studies have suggested that childhood trauma and parental death are strongly associated with suicidality in adulthood, it is still unclear how these factors interact within the same population. A total of 1396 adults were recruited through nationwide multistage probability sampling in South Korea. Subjects were evaluated through face-to-face interviews using the Suicidality Module of the Mini-International Neuropsychiatric Interview and the Early Trauma Inventory Self Report-Short Form. Among the 1396 adults, the group that experienced both childhood trauma and parental death had the highest current suicidality risks (F = 12.16, p < 0.0001) and lifetime suicide attempt (χ2 = 35.81, p < 0.0001) compared with the other groups, which were only childhood trauma, only parental death, and neither. Multivariate logistic regression analyses revealed that middle-to-high current suicidality risk and lifetime suicide attempt were significantly associated with concurrent childhood trauma and parental death (odds ratio, 3.64; 95% confidence interval, 1.99-6.65) as well as with only childhood trauma (odds ratio, 1.95; 95% confidence interval, 1.33-2.87), after adjusting for age, sex, education, marital status, household monthly income, and living area. Emotional abuse was the only type of childhood trauma significantly associated with higher current suicidality scores in those who experienced childhood parental death than in those who did not (F = 3.26, p = 0.041). Current suicidality risk and lifetime suicide attempt are associated with experiencing both parental death and trauma, especially emotional abuse, in childhood, whereas experiencing only childhood parental death is associated with neither.
Introduction Ureteral trauma is rare, accounting for less than 1% of all urologic traumas. However, a missed ureteral injury can result in significant morbidity and mortality. The purpose of this article is to review the literature since 1961 with the primary objective to present the largest medical literature review, to date, regarding ureteral trauma. Several anatomic and physiologic considerations are paramount regarding ureteral injuries management. Literature review Eighty-one articles pertaining to traumatic ureteral injuries were reviewed. Data from these studies were compiled and analyzed. The majority of the study population was young males. The proximal ureter was the most frequently injured portion. Associated injuries were present in 90.4% of patients. Admission urinalysis demonstrated hematuria in only 44.4% patients. Intravenous ureterogram (IVU) failed to diagnose ureteral injuries either upon admission or in the operating room in 42.8% of cases. Ureteroureterostomy, with or without indwelling stent, was the surgical procedure of choice for both trauma surgeons and urologists (59%). Complications occurred in 36.2% of cases. The mortality rate was 17%. Conclusion The mechanism for ureteral injuries in adults is more commonly penetrating than blunt. The upper third of the ureter is more often injured than the middle and lower thirds. Associated injuries are frequently present. CT scan and retrograde pyelography accurately identify ureteral injuries when performed together. Ureteroureterostomy, with or without indwelling stent, is the surgical procedure of choice of both trauma surgeons and urologists alike. Delay in diagnosis is correlated with a poor prognosis.

Acute traumatic injury during pregnancy is a significant contributor to maternal and fetal morbidity and mortality in the United States. Motor vehicle accidents are the leading cause of injury-related maternal death, followed by violence and assault. Lack of seat belts or other restraints increases the risks of both maternal and fetal morbidity and mortality. The American College of Obstetricians and Gynecologists recommends proper seat belt use by all pregnant women and screening for domestic abuse. Maternal injury and death from physical abuse is prevalent, and in some communities, homicide is a major cause of pregnancy-associated maternal death. Blunt trauma most often occurs as a result of motor vehicle accidents, whereas penetrating trauma results from gunshots or stabbings. Blunt trauma to the abdomen increases the risk for placental abruption, and direct fetal injury is more likely with penetrating trauma. Management strategies in acute maternal trauma must focus on a thorough assessment of the mother. A coordinated team effort that includes the obstetrician is essential to ensure optimal maternal and fetal outcomes. Imaging studies should not be delayed because of concerns of fetal radiation exposure, because the risk is minimal with usual imaging procedures, especially in mid-to-late pregnancy. The obstetrician should serve in a consultative role if nonobstetric surgical care is required and must also be prepared to intervene on behalf of the mother and the fetus if trauma care is compromised by the pregnancy. Perimortem cesarean delivery should be considered early in the resuscitation of a pregnant trauma victim, especially when fetal viability is a concern. Once the mother is stabilized in the emergency setting, she should be transported for appropriate maternal and fetal observation until both mother and fetus are clear of danger. It is essential that the clinician and staff maintain thorough and accurate documentation and recording of the chronology of

The risk of overwhelming postsplenectomy infection (OPSI) prompted the evolution toward preservation of the injured spleen. Nonoperative management (NOM) of blunt injury to the spleen in adults has become the standard of care in hemodynamically stable patients. This modality of treatment began in the 1970’s in paediatric patients. It is highly successful with overall failures rates from 2% to 31% (average 10.8%) - with the majority of failures occurring in the first 24 hours. Current, NOM of splenic trauma includes splenic artery embolization. However, the criteria for NOM are controversial. In this study we present the current criteria, the evolution and failure rates of this type of management viewed through the general knowledge and, particularly, our experience. PMID:22574087

This randomized pilot study aimed to determine whether a single session of psychoeducation improved mental health outcomes, attitudes toward treatment, and service engagement among urban, impoverished, culturally diverse, trauma-exposed adults. Sixty-seven individuals were randomly assigned to a single-session psychoeducation treatment or a delayed treatment comparison control group. The control group was found to be superior to the treatment group at posttest with respect to symptoms of posttraumatic stress disorder, anxiety, and occupational and family disability. At follow-up, all participants had completed the psychoeducation treatment, and a mixed-effects model indicated significant improvements over time in symptoms of posttraumatic stress disorder, anxiety, depression, somatization, and attitudes toward treatment. Ninety-eight percent of the participants reported the psychoeducation was helpful at follow-up. Participants also reported a 19.1% increase in mental health service utilization at follow-up compared with baseline. Implications for treatment and future research are discussed.

The present investigation examined the incremental predictive validity of mindfulness-based processes, indexed by the Kentucky Inventory of Mindfulness Skills, in relation to posttraumatic stress symptom severity among individuals without any axis I psychopathology. Participants included 239 adults who endorsed exposure to traumatic life events. Results indicated that the Accepting without Judgment subscale was significantly incrementally associated with posttraumatic stress symptoms; effects were above and beyond the variance accounted for by negative affectivity and number of trauma types experienced. The Acting with Awareness subscale was incrementally associated with only posttraumatic stress-relevant re-experiencing symptoms; and no other mindfulness factors were related to the dependent measures. Findings are discussed in relation to extant empirical and theoretical work relevant to mindfulness and posttraumatic stress.

The Advanced Trauma Life Support guidelines recommend an initial rapid infusion of fluid (1-2 L) in trauma and hemorrhage victims as a diagnostic procedure to aid treatment decisions. Although patient response to initial fluid resuscitation is the key to determining therapeutic strategies, the appropriate rate of infusion is not clearly defined. Ninety-nine adult (age >16 years) blunt trauma victims with hypotension were enrolled. Patients were classified into 3 groups according to hemodynamic state after initial fluid resuscitation and requirement of surgical intervention. Total volume and rate of infusion differed significantly between the groups (P < .05). Patients requiring fluid administration at higher rate were all hemodynamically unstable and required immediate surgical intervention. Moreover, rate of infusion was the best predictor of the patients who required immediate surgical intervention. Moderate fluid infusion rate should be considered to allow identification of the patient's response to initial fluid resuscitation.

Childhood abuse (CA) has been found to be related to the development of a variety of psychiatric disorders in adulthood. Although CA is also associated with adult loneliness, few studies have investigated the role of loneliness as a mediator in the relationship between CA and adult psychopathology. Using data from a large, general population sample a mediation model was proposed and tested. Controlling for a range of background variables, the results from a series of regression analyses found that loneliness mediated the association between CA and six adult psychiatric disorders. The findings of this study highlight the importance of loneliness to the development of psychopathology. Theoretical and practical implications are discussed.

The aim of the present study was to evaluate relationship of self-mutilative behaviour (SMB) with the severity of childhood trauma and adult attention-deficit/hyperactivity disorder (ADHD) symptoms in a sample of inpatients with alcohol use disorder (AUD). Participants included 188 inpatients with AUD. Participants were evaluated with the Self-mutilative Behaviour Questionnaire, the Childhood Trauma Questionnaire (CTQ-28) and the Adult ADD/ADHD DSM-IV Based Diagnostic Screening and Rating Scale (Adult ADHD Scale). Among inpatients with AUD those who have a history of SMB constituted the SMB group (n = 57, 30.3%), and those without a history of SMB constituted the group without SMB (n = 131, 69.7%). Risk of high ADHD risk was 2.5 times higher among those with SMB. Adult ADHD Scale and CTQ-28 scores were also higher in the group with SMB. In the first backward logistic regression model, the severity of ADHD symptoms predicted the presence of SMB, together with the severity of childhood trauma, whereas in the second model, physical neglect and inattentive (IN) dimension of ADHD predicted the presence of SMB. These findings suggest that the higher severity of physical neglect and adult IN dimension of ADHD may be related to SMB among inpatients with AUD.

Records of 100 consecutive patients treated in 1973 through 1977 with post-traumatic retroperitoneal hematomas (RH) were studied. Eighty RH followed blunt injury and 20 were due to penetrating trauma. Overall mortality was 26%. The worst prognosis was associated with RH from automobile accidents and pedestrian injuries. Pelvic RH were almost uniformly associated with pelvic fracture and were the primary cause of 39% of deaths. Blunt perinephric RH required renal exploration in 47% of patients. Blunt RH in other locations were associated with major visceral or vascular injury in half the patients and were the cause of death in five. Sixty-five per cent of RH due to penetrating trauma had visceral or vascular injury requiring operative correction. Contained rupture of descending choracic aorta presented as retrogastric RH in two patients. RH from penetrating trauma should be explored routinely, since 65% are associated with visceral or vascular injury.

Children form a strong attachment to their caregiver—even when that caretaker is abusive. Paradoxically, despite the trauma experienced within this relationship, the child develops a preference for trauma-linked cues—a phenomenon known as trauma bonding. Although infant trauma compromises neurobehavioral development, the mechanisms underlying the interaction between infant trauma bonding (i.e., learned preference for trauma cues) and the long-term effects of trauma (i.e., depressive-like behavior, amygdala dysfunction) are unknown. We modeled infant trauma bonding by using odor-shock conditioning in rat pups, which engages the attachment system and produces a life-long preference for the odor that was paired with shock. In adulthood, this trauma-linked odor rescues depressive-like behavior and amygdala dysfunction, reduces corticosterone (CORT) levels, and exerts repair-related changes at the molecular level. Amygdala microarray after rescue implicates serotonin (5-HT) and glucocorticoids (GCs), and a causal role was verified through microinfusions. Blocking amygdala 5-HT eliminates the rescue effect; increasing amygdala 5-HT and blocking systemic CORT mimics it. Our findings suggest that infant trauma cues share properties with antidepressants and safety signals and provide insight into mechanisms by which infant trauma memories remain powerful throughout life.

Diaphragm injuries after blunt trauma are uncommon but require early diagnosis to expedite repair. The advancing technology of computed tomography (CT) scanners has improved the detection of almost all traumatic injuries; however, the literature regarding the diagnostic accuracy of CT scan for blunt diaphragm injuries is lacking. The purpose of this study was to determine the CT scan findings in the setting of known blunt diaphragm injury. We performed a retrospective review of all blunt trauma patients with a known diaphragm injury confirmed at laparotomy who also had a preoperative CT scan of the torso. Every CT scan was retrospectively reviewed by a board-certified radiologist for evidence of diaphragm injury as well as associated abdominal and thoracic injuries. Forty-two patients sustaining blunt trauma had preoperative CT scans of the torso and a diaphragm injury confirmed at laparotomy. Only 57 per cent of CT scans showed evidence of diaphragmatic injury. The most common thoracic injury identified was a pulmonary contusion (79%). Although the advancement of imaging technology has markedly improved the diagnosis and management of blunt traumatic injuries, the detection of diaphragm injuries using CT continues to be low and reconstructions do not help in finding diaphragm injuries.

The aims of the present study were first to identify discrete patterns of childhood victimization experiences including crime, child maltreatment, peer/sibling victimization, sexual violence, and witnessing violence among adult trauma victims using latent class analysis; second, to examine the association between class-membership and suicidal behavior, and third to investigate the differential role of dispositional anger on the association between class-membership and suicidal behavior. We hypothesized that those classes with accumulating exposure to different types of childhood victimization (e.g., poly-victimization) would endorse higher suicidal behavior, than the other less severe classes, and those in the most severe class with higher anger trait would have stronger association with suicidal behavior. Respondents were 346 adults (N=346; Mage=35.0years; 55.9% female) who had experienced a lifetime traumatic event. Sixty four percent had experienced poly-victimization (four or more victimization experiences) and 38.8% met the cut-off score for suicidal behavior. Three distinct classes emerged namely, the Least victimization (Class 1), the Predominantly crime and sibling/peer victimization (Class 2), and the Poly-victimization (Class 3) classes. Regression analysis controlling for age and gender indicated that only the main effect of anger was significantly associated with suicidal behavior. The interaction term suggested that those in the Poly-victimization class were higher on suicidal behavior as a result of a stronger association between anger and suicidal behavior in contrast to the association found in Class 2. Clinical implications of findings entail imparting anger management skills to facilitate wellbeing among adult with childhood poly-victimization experiences.

Exercise-induced skeletal muscle microtrauma is characterized by loss of muscle cell integrity, marked aseptic inflammatory response, and oxidative stress. We examined if iron supplementation would alter redox status after eccentric exercise. In a randomized, double blind crossover study, that was conducted in two cycles, healthy adults (n = 14) and children (n = 11) received daily either 37 mg of elemental iron or placebo for 3 weeks prior to and up to 72 h after an acute eccentric exercise bout. Blood was drawn at baseline, before exercise, and 72 h after exercise for the assessment of iron status, creatine kinase activity (CK), and redox status. Iron supplementation at rest increased iron concentration and transferrin saturation (p < 0.01). In adults, CK activity increased at 72 h after exercise, while no changes occurred in children. Iron supplementation increased TBARS at 72 h after exercise in both adults and children; no changes occurred under placebo condition. Eccentric exercise decreased bilirubin concentration at 72 h in all groups. Iron supplementation can alter redox responses after muscle-damaging exercise in both adults and children. This could be of great importance not only for healthy exercising individuals, but also in clinical conditions which are characterized by skeletal muscle injury and inflammation, yet iron supplementation is crucial for maintaining iron homeostasis. This study was registered at Clinicaltrials.gov Identifier: NCT02374619. PMID:28203319

Adverse conditions prenatally increase the risk of cardiovascular disease, including hypertension. Chronic hypoxia in utero (CHU) causes endothelial dysfunction, but whether sympathetic vasoconstrictor nerve functioning is altered is unknown. We, therefore, compared in male CHU and control (N) rats muscle sympathetic nerve activity, vascular sympathetic innervation density, and mechanisms of sympathetic vasoconstriction. In young (Y)-CHU and Y-N rats (≈3 months), baseline arterial blood pressure was similar. However, tonic muscle sympathetic nerve activity recorded focally from arterial vessels of spinotrapezius muscle had higher mean frequency in Y-CHU than in Y-N rats (0.56±0.075 versus 0.33±0.036 Hz), and the proportions of single units with high instantaneous frequencies (1-5 and 6-10 Hz) being greater in Y-CHU rats. Sympathetic innervation density of tibial arteries was ≈50% greater in Y-CHU than in Y-N rats. Increases in femoral vascular resistance evoked by sympathetic stimulation at low frequency (2 Hz for 2 minutes) and bursts at 20 Hz were substantially smaller in Y-CHU than in Y-N rats. In Y-N only, the neuropeptide Y Y1-receptor antagonist BIBP3226 attenuated these responses. By contrast, baseline arterial blood pressure was higher in middle-aged (M)-CHU than in M-N rats (≈9 months; 139±3 versus 126±3 mm Hg, respectively). BIBP3226 had no effect on femoral vascular resistance increases evoked by 2 Hz or 20 Hz bursts in M-N or M-CHU rats. These results indicate that fetal programming induced by prenatal hypoxia causes an increase in centrally generated muscle sympathetic nerve activity in youth and hypertension by middle age. This is associated with blunting of sympathetically evoked vasoconstriction and its neuropeptide Y component that may reflect premature vascular aging and contribute to increased risk of cardiovascular disease.

Venous injuries as a result of blunt trauma are rare. Even though current protocols for multidetector computed tomography (CT) of patients with trauma are designed to evaluate primarily the solid organs and arteries, blunt venous injuries may nevertheless be identified, or at least suspected, on the basis of the multidetector CT findings. Venous injuries are associated with high morbidity and mortality rates. Diagnosis of a possible venous injury is crucial because the physical findings of a venous injury are nonspecific and may be absent. This article aims to make the radiologist aware of various venous injuries caused by blunt trauma and to provide helpful hints to aid in the identification of venous injuries. Multidetector CT technology, in combination with interactive manipulation of the raw dataset, can be useful in the creation of multiplanar reconstructed images and in the identification of a venous injury caused by blunt trauma. Familiarity with direct and indirect signs of venous injuries, as well as with examples of blunt traumatic venous injuries in the chest, abdomen, and pelvis, will help in the diagnosis of these injuries.

Objective To evaluate the feasibility and effectiveness of endovascular repair for blunt popliteal arterial injuries. Materials and Methods A retrospective analysis of seven patients with clinical suspicion of popliteal arterial injuries that were confirmed by arteriography was performed from September 2009 to July 2014. Clinical data included demographics, mechanism of injury, type of injury, location of injury, concomitant injuries, time of endovascular procedures, time interval from trauma to blood flow restoration, instrument utilized, and follow-up. All patients were male (mean age of 35.9 ± 10.3 years). The type of lesion involved intimal injury (n = 1), partial transection (n = 2), complete transection (n = 2), arteriovenous fistula (n = 1), and pseudoaneurysm (n = 1). All patients underwent endovascular repair of blunt popliteal arterial injuries. Results Technical success rate was 100%. Intimal injury was treated with a bare-metal stent. Pseudoaneurysm and popliteal artery transections were treated with bare-metal stents. Arteriovenous fistula was treated with bare-metal stent and coils. No perioperative death and procedure-related complication occurred. The average follow-up was 20.9 ± 2.3 months (range 18–24 months). One patient underwent intra-arterial thrombolysis due to stent thrombosis at 18 months after the procedure. All limbs were salvaged. Stent migration, deformation, or fracture was not found during the follow-up. Conclusion Endovascular repair seems to be a viable approach for patients with blunt popliteal arterial injuries, especially on an emergency basis. Endovascular repair may be effective in the short-term. Further studies are required to evaluate the long-term efficacy of endovascular repair. PMID:27587969

Blunt diaphragmatic lesions (BDL) are uncommon in trauma patients, but they should be promptly recognized as a delayed diagnosis increases morbidity and mortality. It is well known that BDL are often overlooked at initial imaging, mainly because of distracting injuries to other organs. Sonography may directly depict BDL only in a minor number of cases. Chest X-ray has low sensitivity in detecting BDL and lesions can be reliably suspected only in case of intra-thoracic herniation of abdominal viscera. Thanks to its wide availability, time-effectiveness and spatial resolution, multi-detector computed tomography (CT) is the imaging modality of choice for diagnosing BDL; several direct and indirect CT signs are associated with BDL. Given its high tissue contrast resolution, magnetic resonance imaging can accurately depict BDL, but its use in an emergency setting is limited because of longer acquisition times and need for patient’s collaboration.

Background: Ventilator-associated pneumonia (VAP) is a type of lung infection that typically affects critically ill patients undergoing mechanical ventilation (MV) in the Intensive Care Unit (ICU). The aim of this analysis is to determine potential association between zinc supplementation with the occurrence of VAP in adult mechanically ventilated trauma patients. Subjects and Methods: This secondary analysis of a prospective observational study was carried out over a period of 1 year in ICUs of one teaching hospital in Iran. A total of 186 adults mechanically ventilated trauma patients, who required at least 48 h of MV and received zinc sulfate supplement (n = 82) or not (n = 104) during their ICU stay, were monitored for the occurrence of VAP until their discharge from the ICU or death. Results: Forty-one of 186 patients developed VAP, 29.09 days after admission (95% confidence interval [CI]: 26.27–31.9). The overall incidence of VAP was 18.82 cases per 1000 days of intubation (95% CI: 13.86–25.57). Patients who received zinc sulfate supplement have smaller hazard of progression to VAP than others (hazard ratio: 0.318 [95% CI: 0.138–0.732]; P < 0.0001). Conclusion: The findings show that zinc supplementation may be associated with a significant reduction in the occurrence of VAP in adult mechanically ventilated trauma patients. Further well-designed randomized clinical trials to confirm the efficacy of this potential preventive modality are warranted. PMID:28197049

Childhood traumatic events may lead to long-lasting psychological effects and contribute to the development of complex posttraumatic sequelae. These might be captured by the diagnostic concept of complex posttraumatic stress disorder (CPTSD) as an alternative to classic posttraumatic stress disorder (PTSD). CPTSD comprises a further set of symptoms in addition to those of PTSD, namely, changes in affect, self, and interpersonal relationships. Previous empirical research on CPTSD has focused on middle-aged adults but not on older adults. Moreover, predictor models of CPTSD are still rare. The current study investigated the association between traumatic events in childhood and complex posttraumatic stress symptoms in older adults. The mediation of this association by 2 social-interpersonal factors (social acknowledgment as a survivor and dysfunctional disclosure) was investigated. These 2 factors focus on the perception of acknowledgment by others and either the inability to disclose traumatic experiences or the ability to do so only with negative emotional reactions. A total of 116 older individuals (age range = 59-98 years) who had experienced childhood traumatic events completed standardized self-report questionnaires indexing childhood trauma, complex trauma sequelae, social acknowledgment, and dysfunctional disclosure of trauma. The results showed that traumatic events during childhood were associated with later posttraumatic stress symptoms but with classic rather than complex symptoms. Social acknowledgment and dysfunctional disclosure partially mediated this relationship. These findings suggest that childhood traumatic stress impacts individuals across the life span and may be associated with particular adverse psychopathological consequences.

Objective To analyze the outcome of hemodynamically stable patients with blunt hepatic injury managed nonoperatively, and to examine the impact of this approach on the outcome of all patients with blunt hepatic injury. Summary Background Data Until recently, operative management has been the standard for liver injury. A prospective trial from the authors’ institution had shown that nonoperative management could safely be applied to hemodynamically stable patients with blunt hepatic injury. The present study reviewed the authors’ institutional experience with blunt hepatic trauma since that trial and compared the results with prior institutional experience. Methods Six hundred sixty-one patients with blunt hepatic trauma during the 5-year period ending December 1998 were reviewed (NONOP2). The outcomes were compared with two previous studies from this institution: operative 1985 to 1990 (OP) and nonoperative 1993 to 1994 (NONOP1). Results All 168 OP patients were managed operatively. Twenty-four (18%) of 136 NONOP1 patients and 101 (15%) of the 661 NONOP2 patients required immediate exploration for hemodynamic instability. Forty-two (7%) patients failed nonoperative management; 20 were liver-related. Liver-related failures of nonoperative management were associated with higher-grade injuries and with larger amounts of hemoperitoneum on computed tomography scanning. Twenty-four-hour transfusions, abdominal infections, and hospital length of stay were all significantly lower in the NONOP1 and NONOP2 groups versus the OP cohort. The liver-related death rate was constant at 4% in the three cohorts over the three time periods. Conclusions Although urgent surgery continues to be the standard for hemodynamically compromised patients with blunt hepatic trauma, there has been a paradigm shift in the management of hemodynamically stable patients. Approximately 85% of all patients with blunt hepatic trauma are stable. In this group, nonoperative management significantly

Introduction Gastric emphysema or pneumatosis is a rare finding. Early endoscopy and urgent laparotomy is advised in post-trauma patients. Case Presentation A 29 year old man presented with blunt abdominal injury following a high-speed motorbike crash He complained of abdominal pain and abdomen was distended. CT abdomen revealed air in the gastric wall with disruption of gastric mucosa. He had normal white cell counts, bleeding parameters and blood gases. He was treated conservatively with nasogastric decompression, intravenous analgesics and antibiotics with which he recovered well. Conclusions Early surgical management is indicated in post-trauma patients in whom bowel infarction is suspected. In a stable patient, a negative laparotomy is a major additional stress post trauma - conservative management with close clinical observation is a suitable management alternative. PMID:24396802

Male genital trauma is a rare but potentially serious sports injury. Although such an injury can occur by many different mechanisms, including falls, collisions, straddle injuries, kicks, and equipment malfunction, the clinical presentation is typically homogeneous, characterized by pain and swelling. Almost all sports-related male genital injury comes from blunt force trauma, with involvement of scrotal structures far more common than penile structures. Most injuries can be treated conservatively, but catastrophic testicular injury must first be ruled out. Despite being relatively uncommon compared with other sports injuries, more than half of all testicular injuries are sustained during sports.

Of 161 patients with blunt thoracic injury, 135 were male (83.9%) and 26 were female. The most common cause of injury was traffic accidents (130 patients, 80.7%), followed by falls (22 patients), and crushing (7 patients). There were 46 third decade and 36 second decade patients. Thirty-two patients had single thoracic injury and the other had multiple organ injury. The most common associated injury was head injury (65 patients). Most traffic accidents involved motor cycle accident. Forty-four patients died, 32 within 24 hours, and 4 died to thoracic injury. These 4 patients were shock on arrival and died within 24 hours. The injury severity score, which was under 30 in 78.3% of patients, correlated to the mortality rate. Rib fracture was the most common thoracic injury in 96 patients followed by hemothorax in 91, pulmonary contusion in 79, and pneumothorax in 64. Most of the thoracic injuries were treated conservatively. Thoracotomy was performed in 6 patients. Other than one patient with rupture of the left pulmonary vein, 5 patients recovered. Continued bleeding at a rate of more than 200 ml/h from the chest drainage tube or no recovery from shock and large air leakage preventing re-expansion of the lung are indications for emergency thoracotomy. Thoracotomy should also be considered after conservative treatment in patients with continued air leakage or intrabronchial bleeding negatively affecting respiration. Indications for thoracotomy should be determined individually based on evaluating of vital sign.

Intestinal injury is frequent after non-penetrating abdominal trauma, particularly after modern, high-energy transfer impacts. Under these circumstances, delay in the diagnosis of perforation is a major contributor to morbidity and mortality. This study establishes patterns of intestinal injury after blunt trauma by non-penetrating projectiles and examines relationships between injury distribution and abdominal wall motion. Projectile impacts of variable momentum were produced in 31 anaesthetised pigs to cause abdominal wall motion of varying magnitude and velocity. No small bowel injury was observed at initial impact velocity of less than 40 m/s despite gross abdominal compression. At higher velocity, injury to the small bowel was frequent, irrespective of the degree of abdominal compression (P = 0.00044). Large bowel injury was observed at all impact velocities and at all degrees of abdominal compression. This study confirms the potential for intestinal injury in high velocity, low momentum impacts which do not greatly compress the abdominal cavity and demonstrates apparent differences in injury mechanisms for the small bowel and colon. Familiarity with injury mechanisms may reduce delays in the diagnosis of intestinal perforation in both military and civilian situations.

Background: Basic epidemiological data can provide estimates when discussing disease burden and in the planning and provision of healthcare strategies. There is little quantitative information in the literature regarding prevalence of traumatic injuries from developing countries. Objectives: The aim of the current preliminary study was to reveal the prevalence and age and gender distribution of various traumatic injuries in a tertiary referral orthopedic hospital in Iran. Patients and Methods: In a prospective descriptive study, all traumatic injured patients attending the Orthopedic Trauma Unit of our center in a five year period were included. Demographic details, the cause of injury, injury classification and treatment were recorded. For each of the five-year age groups and each gender we calculated the numbers with fractures, dislocations, soft tissue injuries, ligamentous injuries and lacerations and derived average age and gender-specific prevalence as well as seasonal variations. Results: A total of 18890 adults were admitted, 13870 (73.4%) males and 5020 (26.6%) females. There were 8204 (43.4%) fractures. The male fracture age distribution curve was unimodal and there was a detectable bimodal pattern in females. Under 65 years males are 3 times more likely to sustain a fracture than females which decreases to equal risk over the age of 65. The most common fracture site was distal radius/ulna (13.8%), followed by tibial diaphysis (8.8%), proximal femur (7.8%), finger phalanges (6.4%), metacarpals (6%) and metatarsals (5.9%). There were seasonal variations in fracture incidence with peaks in February, March and October. The least number of fractures occurred in June. Conclusions: The risk of traumatic injuries is higher among specific age groups with different patterns emerging for men and women. Thus, the descriptive epidemiology will provide useful information for treatment or injury prevention strategies, resource allocation, and training priorities. PMID

The profile and pattern of abdominal trauma is changing with progressing civilisation. We are lacking epidemiological data from most parts of the world. This study was conducted to prepare a database in our set up and look into the pattern of abdominal trauma, make an aetiological correlation of abdominal trauma with the types of injuries, identify the preventable factors causing delay in intervention and, compare the data with the other available national and international data. This prospective, observational study was done in a teaching hospital in a metropolitan city of eastern India. Records of patients with abdominal trauma were collected in predesigned forms, from admission to discharge. Data were analysed applying standard statistical techniques. Males (87.3%) predominated with the age range between 21 and 30 years, and the majority (73.5%) had blunt abdominal trauma. Compression injury (57.3%) commonly caused blunt trauma and stab injuries caused majority of penetrating trauma. The commonest organ injured both in blunt and penetrating trauma was small bowel (30.7% and 33.3% respectively). It was found that prehospital trauma care is virtually non-existent in this region. We are lacking a uniform protocol for the management of abdominal trauma across the hospitals. With the availability of better investigational modalities we are moving more towards a conservative approach to the abdominal trauma patients, especially the blunt abdominal trauma patients with solid organ injuries.

Child maltreatment impacts approximately two million children each year, with physical abuse and neglect the most common form of maltreatment. These children are at risk for mental and physical health concerns and the ability to form positive social relationships is also adversely affected. Child Adult Relationship Enhancement (CARE) is a set of skills designed to improve interactions of any adult and child or adolescent. Based on parent training programs, including the strong evidence-based treatment, Parent-Child Interaction Therapy (PCIT), CARE was initially developed to fill an important gap in mental health services for children of any age who are considered at-risk for maltreatment or other problems. CARE subsequently has been extended for use by adults who interact with children and youth outside of existing mental health therapeutic services as well as to compliment other services the child or adolescent may be receiving. Developed through discussions with Parent-Child Interaction Therapy (PCIT) therapists and requests for a training similar to PCIT for the non-mental health professional, CARE is not therapy, but is comprised of a set of skills that can support other services provided to families. Since 2006, over 2000 caregivers, mental health, child welfare, educators, and other professionals have received CARE training with a focus on children who are exposed to trauma and maltreatment. This article presents implementation successes and challenges of a trauma-informed training designed to help adults connect and enhance their relationships with children considered at-risk.

This study was undertaken to evaluate the frequency, distribution, cause, pattern, and outcome of patients suffering from major trauma in the State of Victoria over a 1-year period. No previous study in Australia has attempted a comprehensive regional analysis of major trauma. All major trauma admissions resulting from blunt, penetrating, and burns injury were identified, and data collected from emergency departments and intensive care log books at 25 major metropolitan and rural hospitals from the January 3, 1992 to February 28, 1993 by onsite data collectors. The total number of patients admitted into the study was 2,944. There were 1,076 major trauma cases with an Injury Severity Score greater than 15 in a population of 4.2 million people. The type of injury was predominantly blunt (87.5%), with only a small percentage of penetrating injuries (6.4%) and burns (6%). Major trauma in pediatric cases is less common (132 cases). The most common causes of injury were road transport (56%) and falls (22%). The overall outcome of the group was favorable when compared with the Major Trauma Outcome Study group (Z = 1.4, M = 0.93, W = 0.52). There was an unexpectedly low number of patients suffering from major trauma. Outcome using Trauma and Injury Severity Score methodology was favorable when compared with North America.

Thyroid crisis, also known as thyroid storm, is a rare complication of thyrotoxicosis that results in a hypermetabolic and hyperadrenergic state. This condition requires prompt recognition and treatment because the mortality from thyroid crisis approaches 30%. Thyrotoxicosis alone will usually not progress to thyroid crisis. Thyroid crisis will typically be precipitated by some concomitant event such as infection, iodine-containing contrast agents, medications such as amiodarone, pregnancy, or surgery. Trauma is a rare precipitator of thyroid crisis. Several published studies have reported thyroid crisis resulting from blunt or penetrating neck trauma. Significant systemic trauma, such as motor vehicle accidents, has also been reported to precipitate thyroid crisis. It is very unusual for minor trauma to precipitate thyroid crisis. In the present study, we report the case of a patient who had incurred relatively minor maxillofacial trauma and developed thyroid crisis 2 weeks after the initial trauma.

Multiple trauma in children is rare so that even large trauma centers will only treat a small number of cases. Nevertheless, accidents are the most common cause of death in childhood whereby the causes are mostly traffic accidents and falls. Head trauma is the most common form of injury and the degree of severity is mostly decisive for the prognosis. Knowledge on possible causes of injury and injury patterns as well as consideration of anatomical and physiological characteristics are of great importance for treatment. The differences compared to adults are greater the younger the child is. Decompression and stopping bleeding are the main priorities before surgical fracture stabilization. The treatment of a severely injured child should be carried out by an interdisciplinary team in an approved trauma center with expertise in pediatrics. An inadequate primary assessment involves a high risk of early mortality. On the other hand children have a better prognosis than adults with comparable injuries.
The Mediating Role of Emotion Dysregulation in the Relations Between Childhood Trauma History and Adult Attachment and Borderline Personality Disorder Features: A Study of Italian Nonclinical Participants.
Fossati, Andrea; Gratz, Kim L; Somma, Antonella; Maffei, Cesare; Borroni, Serena
In order to evaluate if emotion dysregulation significantly mediates the relationships between childhood abuse and adult attachment and borderline personality disorder features, 354 community Italian adults were administered the Borderline Personality Inventory (Leichsenring, 1999a), the Difficulties in Emotion Regulation Scale (Gratz & Roemer, 2004), the Child Abuse and Trauma Scale (Sanders & Becker-Lausen, 1995), and the Attachment Style Questionnaire (Feeney, Noller, & Hanrahan, 1994). Hierarchical regression analyses showed that both childhood abuse and adult attachment were positively associated with emotion dysregulation and borderline personality features; however, only emotional abuse and the attachment dimension of need for approval were common predictors of both dependent variables. No significant interaction effects were detected in regression analyses. Mediation analyses provided support for partial mediation, revealing a significant mediating role of emotion dysregulation in the relationships between both emotional abuse and need for approval and borderline personality features in this community sample.

Objectives This study examines factors associated with availability of tobacco products for marijuana cigars (i.e., blunts) in 50 non-contiguous mid-sized California communities. Methods The study is based on data collected in 943 tobacco outlets. Neighborhood demographics, community adult marijuana prevalence, medical marijuana policy and access to medical marijuana dispensaries and delivery services were included. Results Multilevel logistic regression analyses indicated that compared with small markets, availability of tobacco products associated with use of blunts was significantly higher in convenience stores, smoke/tobacco shops and liquor stores. None of the neighborhood demographics were associated with availability of blunt wrappers and only a small percent of Whites was positively associated with availability of blunt cigars, small cigars or cigarillos at the store. Controlling for outlet type and neighborhood demographics, higher city prevalence of adult marijuana use was associated with greater availability of blunt wrappers. Also, policy that permits medical marijuana dispensaries or private cultivation was positively associated with availability of tobacco products for blunts. Density of medical marijuana dispensaries and delivery services, however, was negatively associated with greater availability of these products at tobacco outlets. Conclusions Results suggest that availability of tobacco products associated with blunts is similar in neighborhoods with different socioeconomic status and racial and ethnic composition. Results also suggest the important role that community norms that support marijuana use or legalization of medical marijuana and medical marijuana policy may play in increasing availability of tobacco products associated with blunts.

Case series Patients: Male, 33 • Male, 18 • Male, 19 Final Diagnosis: Congenital band causing a small bowel obstruction Symptoms: Progressive abdominal pain that eventually becomes excessive Medication: — Clinical Procedure: Laparoscopic band removal Specialty: Surgery Objective: Rare disease Background: Among the causes of constipation are bands and adhesions that lead to obstructions at different points in the intestinal tract. These can occur as a consequence of healing following surgery or trauma. However, an entity known as congenital band exists where a band is present from birth. Here we report three such cases of adults with symptoms of intestinal obstruction, in whom a congenital band was discovered through exploratory laparoscopy. Case Reports: All three of these patients presented lacking a history of any abdominal trauma or previous abdominal surgeries, a fact that is often used to exclude an adhesion as a differential. All three recovered quickly and had relief of their symptoms following surgical intervention. Conclusions: Bands and adhesions are common surgical causes of small bowel obstruction, leading to symptoms such as nausea, vomiting, constipation, and obstipation. These bands almost always result from a prior abdominal surgery or from a recent abdominal trauma. The three cases presented here show a far more unusual picture of a band, one that is congenitally present, as there was an absence of such a history. This is significant because clinical suspicion of a band is often very low due to a lack of distinguishing clinical and diagnostic features, and when the past history is negative. PMID:27713389

Few reliable predictors indicate which depressed individuals respond to antidepressants. Several studies suggest that a history of early-life trauma predicts poorer response to antidepressant therapy but results are variable and limited in adults. The major goal of the present study was to evaluate the role of early-life trauma in predicting acute response outcomes to antidepressants in a large sample of well-characterized patients with major depressive disorder (MDD). The international Study to Predict Optimized Treatment for Depression (iSPOT-D) is a randomized clinical trial with enrollment from December 2008 to January 2012 at eight academic and nine private clinical settings in five countries. Patients (n=1008) meeting DSM-IV criteria for MDD and 336 matched healthy controls comprised the study sample. Six participants withdrew due to serious adverse events. Randomization was to 8 weeks of treatment with escitalopram, sertraline or venlafaxine with dosage adjusted by the participant's treating clinician per routine clinical practice. Exposure to 18 types of traumatic events before the age of 18 was assessed using the Early-Life Stress Questionnaire. Impact of early-life stressors—overall trauma ‘load' and specific type of abuse—on treatment outcomes measures: response: (⩾50% improvement on the 17-item Hamilton Rating Scale for Depression, HRSD17 or on the 16-item Quick Inventory of Depressive Symptomatology—Self-Rated, QIDS_SR16) and remission (score ⩽7 on the HRSD17 and ⩽5 on the QIDS_SR16). Trauma prevalence in MDD was compared with controls. Depressed participants were significantly more likely to report early-life stress than controls; 62.5% of MDD participants reported more than two traumatic events compared with 28.4% of controls. The higher rate of early-life trauma was most apparent for experiences of interpersonal violation (emotional, sexual and physical abuses). Abuse and notably abuse occurring at ⩽7 years of age predicted poorer

Vascular injury in orthopedic trauma is challenging. The risk to life and limb can be high, and clinical signs initially can be subtle. Recognition and management should be a critical skill for every orthopedic surgeon. There are 5 types of vascular injury: intimal injury (flaps, disruptions, or subintimal/intramural hematomas), complete wall defects with pseudoaneurysms or hemorrhage, complete transections with hemorrhage or occlusion, arteriovenous fistulas, and spasm. Intimal defects and subintimal hematomas with possible secondary occlusion are most commonly associated with blunt trauma, whereas wall defects, complete transections, and arteriovenous fistulas usually occur with penetrating trauma. Spasm can occur after either blunt or penetrating trauma to an extremity and is more common in young patients. Clinical presentation of vascular injury may not be straightforward. Physical examination can be misleading or initially unimpressive; a normal pulse examination may be present in 5% to 15% of patients with vascular injury. Detection and treatment of vascular injuries should take place within the context of the overall resuscitation of the patient according to the established principles of the Advanced Trauma Life Support (ATLS) protocols. Advances in the field, made mostly during times of war, have made limb salvage the rule rather than the exception. Teamwork, familiarity with the often subtle signs of vascular injuries, a high index of suspicion, effective communication, appropriate use of imaging modalities, sound knowledge of relevant technique, and sequence of surgical repairs are among the essential factors that will lead to a successful outcome. This article provides a comprehensive literature review on a subject that generates significant controversy and confusion among clinicians involved in the care of trauma patients.

A case is presented of a 24-year-old man who sustained a forceful blow to the right side of the abdomen during a tackle while playing rugby union. The patient was thought to be “winded” and could not play on. He sought medical attention several hours later at the local hospital where initial evaluation revealed mild right iliac fossa tenderness with no signs of peritonism and clinical parameters showed haemodynamic stability. Subsequent ultrasound and CT evaluation revealed a large haematoma involving the caecum and ascending colon. Emergency right haemicolectomy with primary anastomosis was performed to remove the large haematoma within the intact colonic wall. He was observed in the high dependency unit and was discharged after 7 days following an uneventful postoperative course. He continues to make significant progress some 3 months later and a full return to contact sport is being proposed within 9–12 months. PMID:21754953

We present two separate cases of young male patients with congenital kidney anomalies (horseshoe and crossed fused renal ectopia) identified following blunt abdominal trauma. Despite being rare, ectopic and fusion anomalies of the kidneys are occasionally noted in a trauma patient during imaging or upon exploration of the abdomen. Incidental renal findings may influence the management of traumatic injuries to preserve and protect the patient's renal function. Renal anomalies may be asymptomatic or present with hematuria, flank or abdominal pain, hypotension, or shock, even following minor blunt trauma or low velocity impact. It is important for the trauma clinician to recognize that this group of congenital anomalies may contribute to unusual symptoms such as gross hematuria after minor trauma, are readily identifiable during CT imaging, and may affect operative management. These patients should be informed of their anatomical findings and encouraged to return for long-term follow-up. PMID:27895945

Understanding basic ear anatomy and function allows an examiner to quickly and accurately identify at-risk structures in patients with head and ear trauma. External ear trauma (ie, hematoma or laceration) should be promptly treated with appropriate injury-specific techniques. Tympanic membrane injuries have multiple mechanisms and can often be conservatively treated. Temporal bone fractures are a common cause of ear trauma and can be life threatening. Facial nerve injuries and hearing loss can occur in ear trauma.

The purpose of the present research was to examine Deese-Roediger-McDermott false memory for trauma-related and nontrauma-related lists in adolescents and adults with and without documented histories of child sexual abuse (CSA). Individual differences in psychopathology and adult attachment were also explored. Participants were administered free recall and recognition tests after hearing CSA, negative, neutral, and positive Deese-Roediger-McDermott lists. In free recall, CSA and negative lists produced the most false memory. In sharp contrast, for recognition, CSA lists enjoyed the highest d' scores. CSA-group adolescents who evinced greater posttraumatic stress disorder (PTSD) symptoms had higher rates of false memory compared to (a) non-CSA group adolescents with higher PTSD symptom scores (free recall), and (b) CSA-group adolescents with lower PTSD symptom scores (recognition). Regression analyses revealed that individuals with higher PTSD scores and greater fearful-avoidant attachment tendencies showed less proficient memory monitoring for CSA lists. Implications for trauma and memory development and for translational research are discussed.

Substantial theoretical, empirical, and clinical work examines trauma as it relates to individual victims and perpetrators. As trauma professionals, it is necessary to acknowledge facets of institutions, cultures, and communities that contribute to trauma and subsequent outcomes. Systemic trauma-contextual features of environments and institutions that give rise to trauma, maintain it, and impact posttraumatic responses-provides a framework for considering the full range of traumatic phenomena. The current issue of the Journal of Trauma & Dissociation is composed of articles that incorporate systemic approaches to trauma. This perspective extends conceptualizations of trauma to consider the influence of environments such as schools and universities, churches and other religious institutions, the military, workplace settings, hospitals, jails, and prisons; agencies and systems such as police, foster care, immigration, federal assistance, disaster management, and the media; conflicts involving war, torture, terrorism, and refugees; dynamics of racism, sexism, discrimination, bullying, and homophobia; and issues pertaining to conceptualizations, measurement, methodology, teaching, and intervention. Although it may be challenging to expand psychological and psychiatric paradigms of trauma, a systemic trauma perspective is necessary on both scientific and ethical grounds. Furthermore, a systemic trauma perspective reflects current approaches in the fields of global health, nursing, social work, and human rights. Empirical investigations and intervention science informed by this paradigm have the potential to advance scientific inquiry, lower the incidence of a broader range of traumatic experiences, and help to alleviate personal and societal suffering.

Injuries to the great vessels of the torso are commonly seen and managed in busy urban trauma centers. This same injury complex is rarely seen in military conflicts, likely because of the high kinetic energy of weapons causing the wounds seen in this setting. Although most of the great advancements in trauma surgery over the past century have generally resulted from our wartime experience, civilian centers have contributed greatly to the understanding and management of torso vascular injuries. This article reviews the presentation and management of injuries to the great vessels of the torso from major penetrating and blunt trauma.

Extended length of time from injury to definitive vascular repair is considered to be a predictor of amputation in patients with popliteal artery injuries. In an urban trauma center with a rural catchment area, logistical issues frequently result in treatment delays, which may affect limb salvage after vascular trauma. We examined how known risk factors for amputation after popliteal trauma are affected in a more rural environment, where patients often experience delays in definitive surgical treatment. All adult patients admitted to the Level I trauma center, the University of Mississippi Medical Center, with a popliteal artery injury between January 2000 and December of 2007 were identified. Demographic information management and outcome data were collected. Body mass index, mangled extremity severity score (MESS), Guistilo open fracture score, injury severity score, and time from injury to vascular repair were examined. Fifty-one patients with popliteal artery injuries (53% blunt and 47% penetrating) were identified, all undergoing operative repair. There were nine amputations (17.6%) and one death. Patients requiring amputation had a higher MESS, 7.8 versus 5.3 (P < 0.01), and length of stay, 43 versus 15 days (P < 0.01), compared with those with successful limb salvage. Body mass index, injury severity score, Guistilo open fracture score, or time from injury to repair were not different between the two groups. Patients with a blunt mechanism of injury had a slightly higher amputation rate compared with those with penetrating trauma, 25.9 per cent versus 8.3 per cent (P = non significant). MESS, though not perfect, is the best predictor of amputation in patients with popliteal artery injuries. Morbid obesity is not a significant predictor for amputation in patients with popliteal artery injuries. Time from injury to repair of greater than 6 hours was not predictive of amputation. This study further demonstrates that a single scoring system should be used with

The comorbidity of substance use disorder (SUD), depression, and PTSD is common among veterans. Prior research has shown that among veterans with SUD and depression, those with PTSD did not maintain cognitive-behavioral treatment gains as well as those without PTSD. Thus, the current study was designed to evaluate whether adding trauma-focused treatment following an initial group-based integrated cognitive behavioral treatment (ICBT) for SUD and depression improved treatment outcomes. Participants were 123 veterans (89% male) recruited from the VA San Diego Healthcare System. All participants received ICBT in twice weekly, group-delivered sessions for 12 weeks (Phase 1). Participants were then randomized to receive 12 sessions of individual follow-up sessions (Phase 2) utilizing either ICBT or cognitive processing therapy that was modified to integrate SUD treatment (CPT-M). Results indicated that PTSD and depression symptoms slightly improved at the end of Phase 1 group ICBT and further improved through Phase 2 individual treatment (except for participants without PTSD who received CPT-M), with treatment gains maintained one year later. Substance use significantly improved at the end of Phase 1 group ICBT and these improvements were maintained through Phase 2 and the one year follow-up. Participants in the trauma-focused Phase 2 treatment (CPT-M) exhibited similar levels of symptom reduction and maintenance of treatment gains as those in the non-trauma-focused Phase 2 treatment (ICBT). However, there was a slight advantage for Phase 2 CPT-M over Phase 2 ICBT with respect to heavy drinking outcomes for individuals with PTSD. Overall, the combination of group ICBT followed by either CPT-M or ICBT individual therapy appears to be effective for veterans with depression, SUD, and trauma history.

Preceding trauma may play a role in the etiology and pathogenesis of hematogenous bone and joint infections. Among 345 children with an acute hematogenous bone and/or joint infection, 20% reported trauma during a 2-week period leading to infection. Blunt impact, bruises, or excoriations were commonly reported. The rate was similar to that in the general pediatric population obtained from the literature. In the study group, patients with and without trauma were similar in age, serum C-reactive protein and erythrocyte sedimentation rate, length of hospitalization, and late sequelae. Preceding minor trauma did not prove to be significant as an etiological or as a prognostic factor.

Rates of both traumatic event exposure and posttraumatic stress disorder (PTSD; 22%-54%) are disproportionately elevated among people living with HIV/AIDS (PLHA). Trauma and related psychopathology significantly affect quality of life and disease management in this patient population. The current study examined associations between internalized HIV stigma, mindfulness skills, and the severity of PTSD symptoms in trauma-exposed PLHA. Participants included 137 PLHA (14.6% female; Mage = 48.94, SD = 8.89) who reported experiencing on average, five (SD = 2.67) traumatic events; 34% met diagnostic criteria for PTSD. Results indicate that after controlling for sex, age, education, and number of traumatic events, internalized HIV stigma was positively related to overall PTSD symptom severity (β = .16, p < .05) and severity of re-experiencing (β = .19, p < .05) and hyper-arousal (β = .16, p = .05), but not avoidance, PTSD symptom clusters. Among the mindfulness facets measured, acting with awareness was uniquely negatively related to the overall severity of PTSD symptoms (β = -.25, p < .01) and the severity of re-experiencing (β = -.25, p < .05), avoidance (β = -.25, p < .05), and hyper-arousal (β = -.29, p < .01) PTSD symptom clusters. These effects were observed after accounting for covariates and shared variance with other mindfulness facets. Theoretically, the present findings suggest that internalized HIV stigma may serve as a vulnerability factor for the severity of certain PTSD symptoms, whereas acting with awareness may function as a protective or resiliency factor for the severity of PTSD symptoms. Implications for the treatment of trauma-exposed PLHA are discussed.

Despite the high incidence and prognostic relevance of hemorrhagic shock and abdominal and blunt chest trauma in multiply injured patients, there are no animal models combining these injuries. Therefore, we established a new porcine multiple trauma model consisting of blunt chest trauma, penetrating abdominal trauma (two incisions in the right upper liver lobe using a four-edged scalpel and subsequent liver packing), and pressure-controlled hemorrhagic shock with a mean arterial pressure of 30 ± 5 mmHg (a maximum of 45% of the total blood volume). The combined traumatic insult led to severe signs of hemorrhagic shock and impaired pulmonary function. In conclusion, a consistent, reproducible, and clinically relevant porcine model of multisystem injury with controlled (pressure-controlled blood withdrawal) and uncontrolled components of hemorrhage (liver laceration) with the potential for rebleeding was established.

Hemorrhagic shock is a principal cause of death among trauma patients within the first 24 hours after injury. Optimal fluid resuscitation strategies have been examined for nearly a century, more recently with several randomized controlled trials. Hypotensive resuscitation, also called permissive hypotension, is a resuscitation strategy that uses limited fluids and blood products during the early stages of treatment for hemorrhagic shock. A lower-than-normal blood pressure is maintained until operative control of the bleeding can occur. The randomized controlled trials examining restricted fluid resuscitation have demonstrated that aggressive fluid resuscitation in the prehospital and hospital setting leads to more complications than hypotensive resuscitation, with disparate findings on the survival benefit. Since the populations studied in each randomized controlled trial are slightly different, as is the timing of intervention and targeted vitals, there is still a need for a large, multicenter trial that can examine the benefit of hypotensive resuscitation in both blunt and penetrating trauma patients.

Introduction In medico-legal evaluation of trauma patients, the bio-psychological effects of the trauma and the severity of the injuries require to be evaluated. In this study, assuming the fact that psychiatric assessment is not taken into consideration in physical trauma cases, we planned to show the presence of psychological trauma in our medico-legally evaluated patients who presented with different types of traumas and to review the mental findings and diagnoses in trauma victims. Method We retrospectively analyzed the hospital records of 1975 patients aged 18 years or older who presented to the Department of Forensic Medicine at Dokuz Eylül University School of Medicine for medico-legal evaluation between 1999 and 2009. Psychiatric assessment was performed in 142 patients by the Department of Psychiatry. The data contained in medico-legal reports and patient records were then examined with respect to patients’ age, gender, nature of traumatic events, psychiatric diagnoses, descriptive characteristics of the patients, severity of trauma and past history of mental disorder and trauma experience. Results of the medicolegal evaluations were also analyzed. Result Of the 142 patients, 80 (56.3%) were female and their average age was 40.30±17.17 years. The most frequent traumatic events were traffic accidents (29.6%) and violence-related blunt force trauma (28.9%). When the distribution of the most common psychiatric diagnoses was examined, it was found that anxiety disorders were found in 69 cases (48.6%), adjustment disorders were found in 16 cases (11.3%) and mood disorders were found in 12 cases (8.5%). Among anxiety disorders, acute stress disorder (n=39) and post-traumatic stress disorder (PTSD) (n=27) were the most common ones. In 27 cases of the 142, it was determined that, psychiatric symptoms and findings did not meet the diagnostic criteria of any psychiatric disorder. Diagnosis of psychiatric disorder was not significantly related with traumatic

Aim There is evidence that childhood trauma is a risk factor for the development of psychosis and it is recommended that childhood trauma is inquired about in all patients presenting with psychosis. This study aimed to determine the prevalence of childhood trauma in patients in the UK Early Intervention Service based on a case note review. Methods This is a retrospective case note study of 296 patients in an UK Early Intervention Service. Trauma history obtained on service entry was reviewed and trauma experienced categorized. Results were analyzed using crosstab and frequency analysis. Results The mean age of the sample was 24 years, 70% were male, 66% were White, and 23% Asian (ethnicity not documented in 11% of the sample). Approximately 60% of patients reported childhood trauma, 21% reported no childhood trauma, and data were not recorded for the remaining 19%. Among those reporting trauma, the prevalence of most frequently reported traumas were: severe or repeated disruption (21%), parental mental illness (19%), bullying (18%), absence of a parent (13%), and ‘other’ trauma (24%) – the majority of which were victimization events. Sixty-six percent of those reporting trauma had experienced multiple forms of trauma. Conclusion A high prevalence of childhood trauma (particularly trauma related to the home environment or family unit) was reported. This is consistent with other studies reporting on trauma and psychosis. The main weakness of the study is a lack of a control group reporting experience of childhood trauma in those without psychosis. Guidelines recommend that all patients with psychosis are asked about childhood trauma; but in 19% of our sample there was no documentation that this had been done indicating the need for improvement in assessment.

Thoracic trauma remains a major source of morbidity and mortality in injured children, and is second only to brain injuries as a cause of death. The presence of a chest injury increases an injured child's mortality by 20-fold. Greater than 80% of chest injuries in children are secondary to blunt trauma. The compliant chest wall in children makes pulmonary contusions and rib fractures the most common chest injuries in children. Injuries to the great vessels, esophagus, and diaphragm are rare. Failure to promptly diagnose and treat these injuries results in increased morbidity and mortality.
This study deals with the individual and collective memory of Leningrad Siege survivors who experienced mass and prolonged wartime trauma during childhood (1941-44). While much has been published about the Siege, there has to date been no investigation by psychologists into the effects of extreme deprivation on Siege victims apart from one pilot study (Gulina et al., 2005). This study is still underway. Interviews with 80 participants (68 female and 12 male) are analysed and discussed here. Interpretative Phenomenological Analysis (IPA) and content analysis are utilized. Unpublished archival writings by children caught in the Siege have been analysed. The principal method of interpretation is based on a psychoanalytic understanding of child development, mourning and the metabolizing of traumatic experience. The subjective meaning of the Siege experience to individual children is considered.

A 41-year-old man experienced a swollen scrotum three days after a motorcycle accident and presented to our hospital. He had had a primary suture repair for anoperineal trauma in an outside hospital at the time of the injury. He presented to us with general fatigue, low grade fevers, and perineal pain. Abdominal computed tomography showed subcutaneous emphysema from the scrotum to the left chest. The sutured wound had foul-smelling discharge and white exudate. We made the diagnosis of necrotizing fasciitis and immediately opened the sutured wound and performed initial debridement and lavage with copious irrigation. We continued antibiotics and lavage of the wound until the infection was controlled. Fortunately, the necrotizing fasciitis did not worsen and he was discharged after 15 days. Our experience indicates that anoperineal injuries should not be closed without careful and intensive follow-up due to the potential of developing necrotizing fasciitis. PMID:26347831

The human face contains the sense organs and is responsible for essential functions: swallowing, chewing, speech, breathing and communication. It is also and most importantly the seat of a person's identity. Multiple trauma adds a life-threatening dimension to the physical and psychological impact of a facial trauma.

Here we provide evidence that both pharmacological and environmental manipulations similarly blunt the cortisol release in response to an acute stressor in adult zebrafish. Different groups of fish were maintained isolated or group-housed in barren or enriched tanks, and then exposed or not to diazepam or fluoxetine. Acute stress increased cortisol levels in group-housed zebrafish maintained in barren environment. Single-housed zebrafish displayed a blunted cortisol response to stress. Environmental enrichment also blunted the stress response and this was observed in both isolated and group-housed fish. The same blunting effect was observed in zebrafish exposed to diazepam or fluoxetine. We highlighted environmental enrichment as an alternative and/or complimentary therapeutic for reducing stress and as a promoter of animal welfare. PMID:27351465

Background Blunt traumatic cardiac rupture is rare. However, such cardiac ruptures carry a high mortality rate. This study reviews our experience treating blunt traumatic cardiac rupture. Methods This retrospective study included 21 patients who experienced blunt traumatic cardiac rupture from 1999 to 2015. Every patient underwent surgery. Several variables were compared between survivors and fatalities. Results Sixteen of the 21 patients survived, and 5 (24%) died. No instances of intraoperative mortality occurred. The most common cause of injury was a traffic accident (81%). The right atrium was the most common location of injury (43%). Ten of the 21 patients were suspected to have cardiac tamponade. Significant differences were found in preoperative creatine kinase–myocardial band (CK-MB) levels (p=0.042) and platelet counts (p= 0.004) between the survivors and fatalities. The patients who died had higher preoperative Glasgow Coma Scale scores (p=0.007), worse Trauma and Injury Severity Scores (p=0.007), and higher Injury Severity Scores (p=0.004) than those who survived. Conclusion We found that elevated CK-MB levels, a low platelet count, and multi-organ traumatic injury were prognostic factors predicting poor outcomes of blunt cardiac rupture. If a patient with blunt traumatic cardiac rupture has these factors, clinicians should be especially attentive and respond promptly in order to save the patient’s life. PMID:27965920

Background Isolated small gut mesentery injury after blunt abdominal trauma from the steering wheel in road traffic accidents is rare. These are always challenging to diagnose and pose a diagnostic dilemma. Objectives To study the pattern of small gut mesenteric injury by steering wheel blunt abdominal trauma in road traffic accidents in patients who had laparotomy. Patients and Methods A 10-year retrospective study was done to study isolated small gut mesentery injury. Results All patients who had isolated mesenteric small gut injury were males. Jejunal mesentery was involved in 13 whereas 4 had ileal mesentery injury. Tear were longitudinal or transverse. Conclusions Isolated small mesentery injury after blunt abdominal trauma from the steering wheel in road traffic accidents is rare. Tears are either longitudinal or transverse. Suture repair is to be done. Delay in reaching hospital or reaching the diagnosis could lead to morbidity and mortality. Isolated mesenteric injury should be considered in any patient with blunt abdominal trauma from steering wheel injury with no evidence of any solid organ injury in unstable patients. PMID:24350106

Mortality has been shown to be high in patients after trauma nephrectomy (TN). However, there are little data regarding morbidity in survivors. The objective of this study was to determine the morbidity rates associated with TN with attention directed to renal failure (RF) and formation of intra-abdominal abscess (IAA). Patients who underwent TN over a 9-year period (1996 to 2004) were identified from the trauma registry. Records were reviewed for all complications after TN in patients surviving at least 48 hours. Eighty-nine patients were identified with TN; 61 per cent resulted after penetrating trauma. Overall mortality was 34 per cent. Seventy-one patients survived greater than 48 hours; 51 (72%) experienced at least one morbidity. There was no difference in morbidity rates between patients undergoing blunt trauma and those undergoing penetrating trama. Patients with morbidities were significantly older, more severely injured, and had higher mortality rates and longer hospital courses. Infectious complications were seen in 52 per cent, respiratory in 48 per cent, gastrointestinal in 30 per cent, coagulopathy in 25 per cent, and RF and IAA were each seen in 14 per cent of patients. Patients undergoing TN are severely injured with significant morbidity. The results from this study allow us to establish benchmarks to assess complication rates for patients who undergo TN, which can provide prognostic information and goals to improve patient outcomes.

People living with HIV (PLWH) have extensive interpersonal trauma histories and higher rates of posttraumatic stress disorder (PTSD) than the general population. Prolonged exposure (PE) therapy is efficacious in reducing PTSD across a variety of trauma samples; however, research has not examined factors that influence how PTSD symptoms change during PE for PLWH. Using multi-level modeling, we examined the potential moderating effect of number of previous trauma types experienced, whether the index trauma was HIV-related or not, and years since HIV diagnosis on PTSD symptom reduction during a 10-session PE protocol in a sample of 51 PLWH. In general, PTSD symptoms decreased linearly throughout the PE sessions. Experiencing more previous types of traumatic events was associated with a slower rate of PTSD symptom change. In addition, LOCF analyses found that participants with a non-HIV-related versus HIV-related index trauma had a slower rate of change for PTSD symptoms over the course of PE. However, analyses of raw data decreased this finding to marginal. Years since HIV diagnosis did not impact PTSD symptom change. These results provide a better understanding of how to tailor PE to individual clients and aid clinicians in approximating the rate of symptom alleviation. Specifically, these findings underscore the importance of accounting for trauma history and index trauma type when implementing a treatment plan for PTSD in PLWH.

Injuries remain the leading cause of death in children and young adults. Management of multiple trauma patients has improved in recent years by quality initiatives (trauma network, S3 guideline "Polytrauma"). On this basis, strong links with preclinical management, structured treatment algorithms, training standards (ATLS®), clear diagnostic rules and an established risk- and quality management are the important factors of a modern emergency room trauma care. We describe the organizational components that lead to successful management of trauma in hospital.
Background Brief interventions (BIs) have been shown to be effective in modifying hazardous drinking behaviours in a range of settings. However, they are underutilised in hospitals due to resource constraints. We explored the perspectives of admitted trauma patients about the appeal, acceptability and content of a Brief Intervention (BI) delivered via text messages. Methods Thirty mobile phone users (≥16 years old) admitted to Auckland City Hospital as a result of injury were recruited (December 2010 – January 2011). Participants were interviewed face-to-face during their hospital stay using a semi-structured interview guide that explored topics including perceptions of the proposed intervention to reduce hazardous drinking and related harm, and perceived acceptability of an m-health program. Where issues relating to content of messages were raised by participants these were also captured. In addition, a brief survey captured information on demographic information, mobile phone usage and type of phone, along with the frequency of alcohol use. Results 22 of the 30 participants were male, and almost half were aged 20 to 39 years. The majority of participants identified as New Zealand Europeans, six as Māori (New Zealand's indigenous population) and of the remainder two each identified as Pacific and of Asian ethnicity. Most (28/30) participants used a mobile phone daily. 18 participants were deemed to be drinking in a non-hazardous manner, seven were hazardous drinkers, and three were non-drinkers. Most participants (21/30) indicated that text messages could be effective in reducing hazardous drinking and related harms, with more than half (17/30) signalling they would sign-up. Factors identified that would increase receptiveness included: awareness that the intervention was evidence-based; participants readiness-to-change; informative messages that include the consequences of drinking and practical advice; non-judgemental messages; and ease-of-use.

Background: Burn injuries are among the most devastating injuries seen in the emergency units. The epidemiology of this injury varies from one part of the world to another. This is a 3-year report in an attempt to provide information on the current epidemiology of burns in this center. Method: Patients admitted into the University of Calabar Teaching Hospital, with burn injuries were prospectively studied between February 2005 and January 2008. Results: The 59 patients (33 males and 26 females) accounted for 3.7% of trauma patients and their ages ranged from 15 to 70 years (mean 29.4 years). Flame burn was the commonest injury seen in 48 (81.3%) patients because of petrol and kerosene, whereas chemical burn that involved 7 (11.9%) patients ranked second. Morbidity included burns wound infection in 13 (22%) patients and contractures in 6 (10.2%) patients. The outcome was fatal in 15 (25.4%) patients. Conclusion: The establishment of burn support groups dedicated to publicity on prevention based on areas of risk highlighted in this study and provision of financial aid as well as provision of modern burn care facilities would improve outcome.

Childhood trauma is associated with premature declines in health in midlife and old age. Pathways that have been implicated, but less studied include social-emotional regulation, biological programming, and habitual patterns of thought and action. In this study we focused on childhood trauma's influence via alterations in social-emotional regulation to everyday life events, a pathway that has been linked to subsequent health effects. Data from a 30-day daily diary of community residents who participated in a study of resilience in Midlife (n = 191, Mage = 54, SD = 7.50, 54% women) was used to examine whether self-reports of childhood trauma were associated with daily well-being, as well as reported and emotional reactivity to daily negative and positive events. Childhood trauma reports were associated with reporting lower overall levels of and greater variability in daily well-being. Childhood trauma was linked to greater reports of daily negative events, but not to positive events. Focusing on emotional reactivity to daily events, residents who reported higher levels of childhood trauma showed stronger decreases in well-being when experiencing negative events and also stronger increases in well-being with positive events. For those reporting childhood trauma, higher levels of mastery were associated with stronger decreases in well-being with negative events and stronger increases in well-being with positive events, suggesting that mastery increases sensitivity to daily negative and positive events. Our results suggest that childhood trauma may lead to poorer health in midlife through disturbances in the patterns of everyday life events and responses to those events. Further, our findings indicate that mastery may have a different meaning for those who experienced childhood trauma. We discuss social-emotional regulation as one pathway linking childhood trauma to health, and psychosocial resources to consider when building resilience-promoting interventions for

Background: The contemplation for the salvage operations and the nonoperative treatment for the pediatric splenic injuries had increasingly been suggested as the standard case management. Objectives: The study was carried out to identify the risk factors, the presentations, the severities and outcome of the interventions of blunt splenic injuries in the children and adolescents. Materials and Methods: This retrospective review was carried out in a tertiary care hospital in Sikkim on the children and adolescents admitted with splenic injury from January 2005 to December 2009. Splenic injuries were graded with the American Association for the Surgery of Trauma Splenic Injury Scale followed by the operative and nonoperative managements (NOM). Results: Overall 147 cases with the abdominal trauma were diagnosed with splenic injury. Of them, males reported in higher numbers; three-fourths were adolescents with preponderance above 16 years of age. Majority of the cases [n=91(61.90%)] were due to fall from heights and others from road traffic accidents. Immediate surgical interventions was instituted in the hemodynamically unstable cases (n=87) NOM failed in 27 patients; of them eight cases underwent splenectomy, and 19 underwent surgical salvage; 33 were closely followed up by conservative approach with both clinical and CT criteria. Total number of cases in grade III and above was significantly higher than with lower grades of injury. Conclusions: In total 95(64.63%) of the cases were managed with total splenectomy; 19 cases in the initial nonsurgical group underwent salvage operation and 33 cases received NOM. PMID:21769209

Background The consequence of the low rate of penetrating injuries in Europe and the increase in non-operative management of blunt trauma is a decrease in surgeons' confidence in managing traumatic injuries has led to the need for new didactic tools. The aim of this retrospective study was to present the Corso di Chirurgia del Politrauma (Trauma Surgery Course), developed as a model for teaching operative trauma techniques, and assess its efficacy. Method the two-day course consisted of theoretical lectures and practical experience on large-sized swine. Data of the first 126 participants were collected and analyzed. Results All of the 126 general surgeons who had participated in the course judged it to be an efficient model to improve knowledge about the surgical treatment of trauma. Conclusion A two-day course, focusing on trauma surgery, with lectures and life-like operation situations, represents a model for simulated training and can be useful to improve surgeons' confidence in managing trauma patients. Cooperation between organizers of similar initiatives would be beneficial and could lead to standardizing and improving such courses. PMID:16759403

Ultrasound plays a pivotal role in the evaluation of acute trauma patients through the use of multi-site scanning encompassing abdominal, cardiothoracic, vascular and skeletal scans. In a high-speed polytrauma setting, because exsanguinations are the primary cause of trauma morbidity and mortality, ultrasound is used for quick and accurate detection of hemorrhages in the pericardial, pleural, and peritoneal cavities during the primary Advanced Trauma Life Support (ATLS) survey. Volume status can be assessed non-invasively with ultrasound of the inferior vena cava (IVC), which is a useful tool in the initial phase and follow-up evaluations. Pneumothorax can also be quickly detected with ultrasound. During the secondary survey and in patients sustaining low-speed or localized trauma, ultrasound can be used to help detect abdominal organ injuries. This is particularly helpful in patients in whom hemoperitoneum is not identified on an initial scan because findings of organ injuries will expedite the next test, often computed tomography (CT). Moreover, ultrasound can assist in detection of fractures easily obscured on radiography, such as rib and sternal fractures.

The aim of this study was to investigate the characteristics of unilateral tibial plateau fractures among hospitalized adult patients in Xijing Hospital, to evaluate the accuracy of Schatzker classification system and AO/OTA classification system to tibial plateau fractures. We retrospectively analysed clinical data on 274 patients admitted to Xijing Hospital between September 2006 and August 2015. The patients’ demographic characteristics, admission periods and seasons, external causes and fracture types were recorded and summarized. Then the characteristics of tibial plateau fractures and the accuracy rate of these two classification systems were analysed. Schatzker type II fractures and AO/OTA type 41-B3 fractures were the most common types. The external causes differed between genders, types of employment, urban-rural residents and both two systems. In addition, some fractures were difficult to classify using Schatzker or AO/OTA classification system. Rural male physical labourers aged between 30–59 years-old were most likely to suffer from unilateral tibial plateau fractures, due to traffic accidents, falls and indoor activity injuries, or falls from height. We should pay more attention to the related people and professions, which contributed to the high occurrence of tibial plateau fractures. Besides that, further improvements are required for both Schatzker and AO/OTA classification systems. PMID:28074894

Blunt, nonpenetrating injuries of the thoracic aorta are uncommon and associated with a high mortality rate within the first hour. Aortic injury is missed in 1-2% of patients that survive to hospital, and a chronic thoracic aortic aneurysm may subsequently form. We present a case in which a chronic thoracic aortic aneurysm was diagnosed 29 years following a significant motor vehicle accident. We discuss the epidemiology, presentation, and management of this uncommon consequence of blunt, nonpenetrating aortic injury. Our case illustrates an important clinical lesson; a past medical history of trauma should not be overlooked at any patient assessment. PMID:26351610

Background: Trauma represents a global public health concern with an estimated 5 million deaths annually. Moreover, the incidence of blunt traumatic injuries (BTI) particularly road traffic accidents (RTAs) and workplace-related injuries are rising throughout the world-wide. Objectives: We aimed to review the epidemiology and prevention of BTI, in the Arab Middle East. Materials and Methods: A traditional narrative literature review was carried out using PubMed, MEDLINE and EMBASE search engines. We used the keywords “traumatic injuries”, “blunt” “epidemiology”, “Arab Middle East” between December 1972 and March 2013. Results: The most common mechanisms of BTI in our region are RTAs, falls from height, struck by heavy objects and pedestrian motor vehicle trauma crashes. The rate of RTA and occupational injuries are markedly increased in the region due to rapid industrial development, extreme climatic conditions and unfamiliar working environment. However, lack of reliable information on these unintentional injuries is mainly responsible for the underestimation of this trauma burden. This knowledge deficit shields the extent of the problem from policy makers, leading to continued fatalities. These preventable injuries in turn add to the overall financial burden on the society through loss of productivity and greater need of medical and welfare services. Conclusion: In the Arab Middle East, population-based studies on the incidence, mechanism of injury, prevention and outcome of BTI are not well-documented. Therefore, region-specific BTI studies would strengthen surveillance to better understand the burden of these injuries in the region. PMID:24812453

Background: CT is increasingly used during the initial evaluation of blunt trauma patients. In this era of increasing cost-awareness, the pros and cons of CT have to be assessed. Objectives: This study was performed to evaluate cost-consequences of different diagnostic algorithms that use thoracoabdominal CT in primary evaluation of adult patients with high-energy blunt trauma. Materials and Methods: We compared three different algorithms in which CT was applied as an immediate diagnostic tool (rush CT), a diagnostic tool after limited conventional work-up (routine CT), and a selective tool (selective CT). Probabilities of detecting and missing clinically relevant injuries were retrospectively derived. We collected data on radiation exposure and performed a micro-cost analysis on a reference case-based approach. Results: Both rush and routine CT detected all thoracoabdominal injuries in 99.1% of the patients during primary evaluation (n = 1040). Selective CT missed one or more diagnoses in 11% of the patients in which a change of treatment was necessary in 4.8%. Rush CT algorithm costed € 2676 (US$ 3660) per patient with a mean radiation dose of 26.40 mSv per patient. Routine CT costed € 2815 (US$ 3850) and resulted in the same radiation exposure. Selective CT resulted in less radiation dose (23.23 mSv) and costed € 2771 (US$ 3790). Conclusions: Rush CT seems to result in the least costs and is comparable in terms of radiation dose exposure and diagnostic certainty with routine CT after a limited conventional work-up. However, selective CT results in less radiation dose exposure but a slightly higher cost and less certainty. PMID:25337521

Massive hematoma of the corpus callosum caused by blunt head trauma is an extremely rare lesion. Most frequent traumatic lesions involve the corpus callosum are diffuse axonal injuries. They might be associated with small hemorrhagic foci in the hemispheric and brain stem white matter, intraventricular hemorrhages, subarachnoid hemorrhages, traumatic lesions of the septum pellucidum and fornix. Many cases of corpus callosum injury present with permanent disconnection syndrome. We present a case of a 32-year-old female suffered blunt head trauma resulted in massive corpus callosum hematoma which was managed non-surgically. The patient initially had a reduced conscious level and symptoms of disconnection syndrome, and significant recovery was observed at 6 months follow up.

Background The initial nonoperative management (NOM) of blunt splenic injuries in hemodynamically stable patients is common. In soldiers who experience blunt splenic injuries with concomitant severe brain injury while on deployment, however, NOM may put the injured soldier at risk for secondary brain injury from prolonged hypotension. Methods We conducted a decision analysis using a Markov process to evaluate 2 strategies for managing hemodynamically stable patients with blunt splenic injuries and severe brain injury — immediate splenectomy and NOM — in the setting of a field hospital with surgical capability but no angiography capabilities. We considered the base case of a 40-year-old man with a life expectancy of 78 years who experienced blunt trauma resulting in a severe traumatic brain injury and an isolated splenic injury with an estimated failure rate of NOM of 19.6%. The primary outcome measured was life expectancy. We assumed that failure of NOM would occur in the setting of a prolonged casualty evacuation, where surgical capability was not present. Results Immediate splenectomy was the slightly more effective strategy, resulting in a very modest increase in overall survival compared with NOM. Immediate splenectomy yielded a survival benefit of only 0.4 years over NOM. Conclusion In terms of overall survival, we would not recommend splenectomy unless the estimated failure rate of NOM exceeded 20%, which corresponds to an American Association for the Surgery of Trauma grade III splenic injury. For military patients for whom angiography may not be available at the field hospital and who require prolonged evacuation, immediate splenectomy should be considered for grade III–V injuries in the presence of severe brain injury.

Introduction: Nonoperative management (NOM) has become the treatment of choice for hemodynamically stable patients with blunt splenic injury. Results of outcome after NOM are predominantly based on large-volume studies from level 1 trauma centers in the United States. This study was designed to assess the results of NOM in a relatively low-volume Dutch level 1 trauma center. Methods: An analysis of a prospective trauma registry was performed for a 6-year period before (period 1) and after the introduction and implementation of splenic artery embolization (SAE) (period 2). Primary outcome was the failure rate of initial treatment. Results: A total of 151 patients were reviewed. An increased use of SAE and a reduction of splenic operations during the second period was observed. Compared with period 1, the failure rate after observation in period 2 decreased from 25% to 10%. The failure rate after SAE in period 2 was 18%. The splenic salvage rate (SSR) after observation increased from 79% in the first period to 100% in the second period. During the second period, all patients with failure after observation were successfully treated with SAE. The SSR after SAE in periods 1 and 2 was respectively 100% and 86%. Conclusions: SAE of patients with blunt splenic injuries is associated with a reduction in splenic operations. The failure and splenic salvage rates in this current study were comparable with the results from large-volume studies of level 1 trauma centers. Nonoperative management also is feasible in a relatively low-volume level 1 trauma center outside the United States.

Introduction Pancreatic lesions are very infrequent after closed abdominal trauma (5% of cases) with a complication rate that affects 30–40% of patients, and a mortality rate that can reach 39%. In our experience, closed abdominal traumatisms occurring at typical popular horse-riding festivals in our region constitute a high risk of pancreatic trauma. The purpose of the present paper is to raise awareness about our experience in the diagnosis and treatment of pancreatic lesions secondary to closed abdominal traumatism. Presentation of case We present the clinical cases of two young patients who, after suffering blunt abdominal trauma secondary to the impact of a horse during the celebration of typical horse-riding festival, were diagnosed with pancreatic trauma type III. The treatment was surgical in both cases and consisted in performing a pancreaticogastric anastomosis with preservation of the distal pancreas and spleen. The postoperative period was uneventful and, at present, both patients are asymptomatic. Discussion Signs and symptoms caused by pancreatic lesion are unspecific and difficult to objectify. With some limitations CT is the imaging test of choice for diagnosis and staging in the acute phase. The Wirsung section is indication for surgical treatment. The most extended surgical procedure in these cases is the resection of pancreatic body, tail, and spleen. Conclusion The identification of a pancreatic injury after closed abdominal trauma requires a high suspicion based on the injury mechanism. A safer option may be the distal pancreatic preservation with pancreaticogastric anastomosis in grade III lesions with healthy pancreatic tissue. PMID:25744560

OBJECTIVE Blunt cerebrovascular injuries (BCVIs) affect approximately 1% of patients with blunt trauma. An antithrombotic or anticoagulation therapy is recommended to prevent the occurrence or recurrence of neurovascular events. This treatment has to be carefully considered after severe traumatic brain injury (TBI), due to the risk of intracranial hemorrhage expansion. Thus, the physician in charge of the patient is confronted with a hemorrhagic and ischemic risk. The main objective of this study was to determine the incidence of BCVI after severe TBI. METHODS The authors conducted a prospective, observational, single-center study including all patients with severe TBI admitted in the trauma center. Diagnosis of BCVI was performed using a 64-channel multidetector CT. Characteristics of the patients, CT scan results, and outcomes were collected. A multivariate logistic regression model was developed to determine the risk factors of BCVI. Patients in whom BCVI was diagnosed were treated with systemic anticoagulation. RESULTS In total, 228 patients with severe TBI who were treated over a period of 7 years were included. The incidence of BCVI was 9.2%. The main risk factors were as follows: motorcycle crash (OR 8.2, 95% CI 1.9-34.8), fracture involving the carotid canal (OR 11.7, 95% CI 1.7-80.9), cervical spine injury (OR 13.5, 95% CI 3.1-59.4), thoracic trauma (OR 7.3, 95% CI 1.1-51.2), and hepatic lesion (OR 13.3, 95% CI 2.1-84.5). Among survivors, 82% of patients with BCVI received systemic anticoagulation therapy, beginning at a median of Day 1.5. The overall stroke rate was 19%. One patient had an intracranial hemorrhagic complication. CONCLUSIONS Blunt cerebrovascular injuries are frequent after severe TBI (incidence 9.2%). The main risk factors are high-velocity lesions and injuries near cervical arteries.

Blunt traumatic abdominal aortic dissection is extremely rare and potentially deadly. We present the case of a 62-year-old man involved in a frontal car crash. After emergency undergoing laparotomy for bowel injuries, he was referred to our hospital due to acute ischemia of bilateral lower extremities on day 3 after the trauma. Computed tomography and aortography showed an aortobiiliac dissection with complete occlusion. This injury was successfully treated by endovascular treatment with 'kissing'-technique stent placement, which appears to be a safe, effective, and minimally invasive treatment.

The charts of 127 consecutive patients who sustained renal trauma between December 1977 and January 1984 were reviewed in order to relate the results of intravenous pyelogram (IVP) to the magnitude of renal pathology. Eighty-eight cases resulted from blunt trauma and 39 cases had penetrating injuries. There were 34 gunshot wounds and five stab wounds. An IVP was performed in 116 patients. All cases of blunt trauma with an IVP reported as normal had no renal pathology greater than contusion. Intravenous pyelogram results in penetrating injuries had a 75% false negative rate. Findings of nonvisualization or extravasation were significant for fractures, perforation, or pedicle injuries in all trauma. Eight of the patients with nonpenetrating wounds and 37 of the patients with penetrating injury underwent exploratory laparotomy. Sixteen nephrectomies were performed for a nephrectomy rate of 12.6% of the total series. This nephrectomy rate is comparable to similar studies which are reviewed.
Traumatic injuries to the scrotum are uncommon but, when they do occur, frequently lead to serious complications. Early complications include testicular infarction, necrosis and abscess formation; in the longer-term trauma may result in testicular atrophy and subfertility. Early surgical intervention in patients with testicular rupture can significantly improve the clinical outcome and reduce the need for delayed orchidectomy. However, clinical examination of the scrotum following trauma is difficult and frequently inaccurate; this may result in incorrect triage of patients for surgical exploration. Scrotal ultrasound can reliably assess scrotal injuries and diagnose testicular rupture with a high level of accuracy. Additionally, ultrasound can provide important information regarding testicular perfusion, which can further inform decisions on surgical management. This article reviews the sonographic findings that may be encountered in patients with scrotal trauma, with an emphasis on blunt trauma. It describes the pivotal role that ultrasound can play in the accurate triage of these patients to surgical or conservative management. PMID:27433221

Upper extremity trauma can be penetrating or blunt in etiology. The close proximity of vein, artery and nerve makes for a complicated presentation and potentially complicated reconstruction. Orthopedic and neurologic injuries can cause the more long term disability of these patients, but vascular injuries are initially more life threatening. Control of vascular injuries can be particularly difficult due to anatomic issues in the upper extremities. The intervention carried significant morbidity until evolution to endovascular approaches occurred. By reconstructing the injury from a more ''remote'' access site, less concomitant injury to the extremity can be encountered. However, although control of vascular injuries may result in greater survival rates with less morbidity from the procedure, long term outcome remains dependent upon concomitant injuries. This review will encompass both vascular and neurologic injuries secondary to trauma to the upper extremity and outline some of the trends in management.

Hepatic trauma is a common cause for admissions in the Emergency Room. Currently, non-surgical management is the standard treatment in haemodynamically stable patients with a success rate of around 85 to 98%. This haemodynamic stability is the most important factor in selecting the appropriate patient. Adjuncts in non-surgical management are angioembolisation, image-guided drainage and endoscopic retrograde cholangiopancreatography. Failure in non-surgical management is relatively rare but potentially fatal, and needs to be recognised and aggressively treated as early as possible. The main cause of failure in non-surgical management is persistent haemorrhage. The aim of this paper is to describe current evidence and guidelines that support non-surgical management of liver injuries in blunt trauma.

Seatbelt associated blunt trauma to the rectum is a rare but well recognised injury. The exact mechanism of hollow visceral injury in blunt trauma is unclear. Stress and shear waves generated by abdominal compression may in part account for injury to gas containing structures. A ‘seatbelt sign’ (linear ecchymosis across the abdomen in the distribution of the lap belt) should raise the suspicion of hollow visceral injuries and can be more severe with disruption of the abdominal wall musculature. Three consecutive cases of rectal injury following blunt abdominal trauma, requiring emergency laparotomy and resection, are described. Lumbar spine injury occurred in one case and in the other two cases, there was injury to the iliac wing of the pelvis; all three cases sustained significant abdominal wall contusion or muscle disruption. Abdominal wall reconstruction and closure posed a particular challenge, requiring a multidisciplinary approach. The literature on this topic is reviewed and potential mechanisms of injury are discussed. PMID:26741660

Background The optimal time to initiate venous thromboembolism pharmacoprophylaxis after blunt abdominal solid organ injury is unknown. Methods Postinjury coagulation status was characterized using thromboelastography (TEG) in trauma patients with blunt abdominal solid organ injuries; TEG was divided into 12-hour intervals up to 72 hours. Results Forty-two of 304 patients (13.8%) identified underwent multiple postinjury thromboelastographic studies. Age (P = .45), gender (P = .45), and solid organ injury grade (P = .71) were similar between TEG and non-TEG patients. TEG patients had higher Injury Severity Scores compared with non-TEG patients (33.2 vs 18.3, respectively, P < .01). Among the TEG patients, the shear elastic modulus strength and maximum amplitude values began in the normal range within the first 12-hour interval after injury, increased linearly, and crossed into the hypercoagulable range at 48 hours (15.1 ± 1.9 Kd/cs and 57.6 ± 1.6 mm, respectively; P < .01, analysis of variance). Conclusions Patients sustaining blunt abdominal solid organ injuries transition to a hypercoagulable state approximately 48 hours after injury. In the absence of contraindications, pharmacoprophylaxis should be considered before this time for effective venous thromboembolism prevention. PMID:24112665

Introduction The aim of this study was to determine the prevalence and the features of deliberate self-harm (DSH) behavior in patients admitted to the psychiatric outpatient clinic for adolescents and young adults and also to detect the association between the act of DSH and childhood traumas. Method In this study, we included all patients who were admitted to the secondary-care psychiatric outpatient clinic for adolescents and young adults in Bakırkoy Research and Training Hospital Psychiatry, Neurology and Neurosurgery throughout a month. A sociodemographic data form, the Childhood Trauma Questionnaire (CTQ-28), Childhood Abuse and Neglect Question List and the Deliberate Self-Harm and Intent Screening Form were applied to three hundred participants. Result The prevalence of DSH was 50.0% among the participants (56.8% for females and 28.8% for males). Childhood abuse was detected in 57.0% of all participants (60.4% of females and 46.6% of males). Among patients with act of DSH, the rate of childhood abuse was 71.3%, while it was 42.7% in the subjects without act of DSH. Conclusion DSH is a common behavior among adolescent psychiatric patients. It is more common in females than in males. The prevalence of experience of childhood abuse and neglect is remarkably high and is associated with self-harm behavior.

Domestic violence (DV) and other experienced trauma types increase the risk for impaired functioning. Access to social resources may provide a buffer to existing risks and allow individuals to continue and build functioning. This cross-sectional study investigated the direct effects of DV and access to social resources (perceived social support, social integration, and frequency of social contact), as well as their potential interactive effects, on daily functioning among 894 male and female trauma survivors who attended primary care clinics in Kurdistan, Iraq in 2009 and 2010. Experiencing DV was not associated with functioning for males (p=.15) or females (p=.60), suggesting that in the context of a trauma-affected sample, the experience of DV may not significantly increase the risk for functional impairment. Greater amounts of social integration were associated with less functional impairment among males (p<.01) and females (p<.05); social integration was associated with less functional impairment among males only (p<.01); and frequency of social contact was associated with less functional impairment among females only (p<.05), indicating that the association between social resource type and functioning differed by gender. Social resources had a stronger effect on functioning among men compared to women. Among males who experienced DV, social integration was the only social resource associated with less functional impairment (p<.01); among male trauma survivors who did not experience DV, social support was the only resource associated with less functional impairment (p<.01). Further investigation into these associations is warranted to inform intervention strategies for survivors of DV and other traumas in post-conflict settings.

Videothoracoscopy represents a valid and useful approach in some patients with blunt chest trauma or penetrating thoracic injury. This technique has been validated for the treatment of clotted hemothorax or posttraumatic empyema, traumatic chylothorax, traumatic pneumothorax, in patients with hemodynamic stability. Moreover, it is probably the most reliable technique for the diagnosis of diaphragmatic injury. It is also useful for the extraction of intrathoracic projectiles and foreign bodies. This technique might be useful in hemodynamically stable patients with continued bleeding or for the exploration of patients with penetrating injury in the cardiac area, although straightforward data are lacking to confirm those indications. Thoracotomy or median sternotomy remain indicated in patients with hemodynamic instability or those that cannot tolerate lateral decubitus position or one-lung ventilation. Performing video-surgery in the trauma setting require expertise in both video-assisted thoracic surgery and chest trauma management. The contra-indications to videothoracoscopy and indications for converting the procedure to an open thoracotomy should be perfectly known by surgeons performing video-assisted thoracic surgery in the trauma setting. Conversion to thoracotomy or median sternotomy should be performed without delay whenever needed to avoid blood loss and achieve an adequate procedure.

Blunted affect, also referred to as emotional blunting, is a prominent symptom of schizophrenia. Patients with blunted affect have difficulty in expressing their emotions. The work of Abrams and Taylor and their development of the Rating Scale for Emotional Blunting in the late 1970’s was an early indicator that blunted affect could indeed be assessed reliably. Since then, several new instruments assessing negative symptoms with subscales measuring blunted affect have been developed. In light of this, we aim to provide researchers and clinicians with a systematic review of the different instruments used to assess blunted affect by providing a comparison of the type, characteristics, administration and psychometric properties of these instruments. Studies reporting on the psychometric properties of instruments assessing blunted affect in patients with schizophrenia were included. Reviews and case studies were excluded. We reviewed 30 full-text articles and included 15 articles and 10 instruments in this systematic review. On average the instruments take 15–30 minutes to administer. We found that blunted affect items common across all instruments assess: gestures, facial expressions and vocal expressions. The CAINS Self-report Expression Subscale, had a low internal consistency score. This suggests that this sub-scale does not reliably assess patients’ self-reported blunted affect symptoms and is likely due to the nature of blunted affect. Instruments correlated minimally with instruments measuring positive symptoms and more importantly with depression suggesting that the instruments distinguish between seemingly similar symptoms.

We examined the impact of a trauma system on the survival of patients with a Trauma Score of 8 or less. We compared the observed survival with that predicted using a method that calculates the probability of survival (Ps) based on age, physiologic score, and anatomic severity of injury. Of 3394 patients triaged to trauma centers in a 12-month period, 283 (8.3%) had a Trauma Score of 8 or less. Sufficient data were available in 189 patients with blunt trauma to make the survival comparison. The Ps was 18%; the observed survival was 29%. Of 60 patients with penetrating trauma and complete data, the Ps was 8%; the observed survival was 20%. We attribute the improved survival to the integration of prehospital and hospital care and expeditious surgery.

A case of choroidal rupture caused by airbag-associated blunt eye trauma and complicated with massive subretinal hemorrhage and vitreous hemorrhage that was successfully treated with intravitreal injection of expansile gas and bevacizumab is presented. A 53-year-old man suffered from loss of vision in his right eye due to blunt eye trauma by a safety airbag after a traffic accident. On initial examination, the patient had no light perception in his right eye. Dilated ophthalmoscopy revealed massive subretinal hemorrhage with macular invasion and faint vitreous hemorrhage. We performed intravitreal injection of pure sulfur hexafluoride twice for displacement, after which visual acuity improved to 0.03. For persistent subretinal hemorrhage and suspicion of choroidal neovascularization (CNV), intravitreal bevacizumab (1.25 mg/0.05 mL) injection was administered. After 3 weeks, the visual acuity of his right eye recovered to 0.4. For early-stage choroidal rupture-induced subretinal hemorrhage and complications of suspected CNV, intravitreal injection of expandable gas and intraocular injection of antiangiogenesis drugs seem to be an effective treatment.

Abdominal trauma accounts for nearly 20% of all severe traffic injuries and can often result from intentional physical violence, from which blunt liver injury is regarded as the most common result and is associated with a high mortality rate. Liver injury may be caused by a direct impact with a certain velocity and energy on the abdomen, which may result in a lacerated liver by penetration of fractured ribs. However, liver ruptures without rib cage fractures were found in autopsies in a series of cases. All the victims sustained punches on the abdomen by fist. Many studies have been dedicated to determining the mechanism underlying hepatic injury following abdominal trauma, but most have been empirical. The actual process and biomechanism of liver injury induced by blunt impact on the abdomen, especially with intact ribs remained, are still inexhaustive. In order to investigate this, finite element methods and numerical simulation technology were used. A finite element human torso model was developed from high resolution CT data. The model consists of geometrically-detailed liver and rib cage models and simplified models of soft tissues, thoracic and abdominal organs. Then, the torso model was used in simulations in which the right hypochondrium was punched by a fist from the frontal, lateral, and rear directions, and in each direction with several impact velocities. Overall, the results showed that liver rupture was primarily caused by a direct strike of the ribs induced by blunt impact to the abdomen. Among three impact directions, a lateral impact was most likely to cause liver injury with a minimum punch speed of 5 m/s (the momentum was about 2.447 kg.m/s). Liver injuries could occur in isolation and were not accompanied by rib fractures due to different material characteristics and injury tolerance.

Background : The liver is the most injured organ in abdominal trauma. Currently, the treatment in most cases is non-operative, but surgery may be necessary in severe abdominal trauma with blunt liver damage, especially those that cause uncontrollable bleeding. Despite the damage control approaches in order to achieve hemodynamic stability, many patients develop hypovolemic shock, acute liver failure, multiple organ failure and death. In this context, liver transplantation appears as the lifesaving last resource Aim : Analyze the use of liver transplantation as a treatment option for severe liver trauma. Methods : Were reviewed 14 articles in the PubMed, Medline and Lilacs databases, selected between 2008-2014 and 10 for this study. Results : Were identified 46 cases undergoing liver transplant after liver trauma; the main trauma mechanism was closed/blunt abdominal trauma in 83%, and severe trauma (>grade IV) in 81 %. The transplant can be done, in this context, performing one-stage procedure (damaged organ removed with immediate transplantation), used in 72% of cases. When the two-stage approach is performed, end-to-side temporary portacaval shunt is provided, until new organ becomes available to be transplanted. If two different periods are considered - from 1980 to 2000 and from 2000 to 2014 - the survival rate increased significantly, from 48% to 76%, while the mortality decreased from 52% to 24%. Conclusion : Despite with quite restricted indications, liver transplantation in hepatic injury is a therapeutic modality viable and feasible today, and can be used in cases when other therapeutic modalities in short and long term, do not provide the patient survival chances.

Background Blunt main stem bronchial injuries are rare but potentially life-threatening injuries in clinical. The aim of this study was to sum up the experience on diagnosis and treatment of blunt main stem bronchial injuries. Methods This report retrospective1y analyzed eight cases of main stem bronchial injuries induced by blunt chest trauma between 2013 and 2016 in Tangdu Hospital, Fourth Military Medical University. Results There were eight patients, including four men and four women. The definitive diagnosis was confirmed by fibrobronchoscopy. Mean time between injury and treatment in our hospital was 4.25 days (range, 1–12 days). Mean length of airway tear was 1.04 cm (range, 0.5–2 cm). In four patients there was an injury to the left main stem bronchus, in three patients to the right main stem bronchus and in one patient to the ambilateral main stem bronchus. Emergent operation was performed in two patients and elective operation in six patients. End to end bronchial anastomosis was performed via right thoracotomy in two patients and via left thoracotomy in three patients, and primary repair was performed via right thoracotomy in two patients and via left thoracotomy in the remaining one patient. There was no death in this group. Seven patients had no complications and were able to take part in normal activities. One patient suffered from anastomotic stricture after operation was healed by granulation tissue resection and cryotherapy under fibrobronchoscopy. Conclusions Fibrobronchoscopy is able to define the blunt main stem bronchial injuries precisely and surgical approach is the preferred method for patients with these life-threatening complications.

Background: In Peru, 11% of deaths are due to trauma. Iquitos is a large underserved Peruvian city isolated from central resources by its geography. Our objective was to implement a locally driven trauma registry to sustainably improve trauma healthcare in this region. Methods: All trauma patients presenting to the main regional referral hospital were included in the trauma registry. A pilot study retrospectively analyzed data from the first two months after implementation. Results: From March to April 2013, 572 trauma patients were entered into the database. Average age was 26.9 years. Ten percent of patients presented more than 24 hours after injury. Most common mechanisms of injury were falls (25.5%), motor vehicle collisions (23.3%), and blunt assault (10.5%). Interim analysis revealed that 99% of patients were entered into the database. However, documentation of vital signs was poor: 42% of patients had temperature, 26% had oxygen saturation documented. After reporting to registry staff, a significant increase in temperature (42 to 97%, P < 0.001) and oxygen saturation (26 to 92%, P < 0.001) documentation was observed. Conclusion: A trauma registry is possible to implement in a resource-poor setting. Future efforts will focus on analysis of data to enhance prevention and treatment of injuries in Iquitos.

Background Advanced prehospital interventions for severe brain injury remains controversial. No previous randomised trial has been conducted to evaluate additional physician intervention compared with paramedic only care. Methods Participants in this prospective, randomised controlled trial were adult patients with blunt trauma with either a scene GCS score <9 (original definition), or GCS<13 and an Abbreviated Injury Scale score for the head region ≥3 (modified definition). Patients were randomised to either standard ground paramedic treatment or standard treatment plus a physician arriving by helicopter. Patients were evaluated by 30-day mortality and 6-month Glasgow Outcome Scale (GOS) scores. Due to high non-compliance rates, both intention-to-treat and as-treated analyses were preplanned. Results 375 patients met the original definition, of which 197 was allocated to physician care. Differences in the 6-month GOS scores were not significant on intention-to-treat analysis (OR 1.11, 95% CI 0.74 to 1.66, p=0.62) nor was the 30-day mortality (OR 0.91, 95% CI 0.60 to 1.38, p=0.66). As-treated analysis showed a 16% reduction in 30-day mortality in those receiving additional physician care; 60/195 (29%) versus 81/180 (45%), p<0.01, Number needed to treat =6. 338 patients met the modified definition, of which 182 were allocated to physician care. The 6-month GOS scores were not significantly different on intention-to-treat analysis (OR 1.14, 95% CI 0.73 to 1.75, p=0.56) nor was the 30-day mortality (OR 1.05, 95% CI 0.66 to 1.66, p=0.84). As-treated analyses were also not significantly different. Conclusions This trial suggests a potential mortality reduction in patients with blunt trauma with GCS<9 receiving additional physician care (original definition only). Confirmatory studies which also address non-compliance issues are needed. Trial registration number NCT00112398. PMID:25795741

History of childhood trauma (CT) is highly prevalent and may lead to long-term consequences on physical and mental health. This study investigated the independent association of CT with symptoms of adult depression and posttraumatic stress disorder (PTSD), mental and physical health-related quality of life (HRQoL), as well as current tobacco consumption and alcohol abuse in a large homogenous cohort of 1254 never-deployed, young male Marines enrolled in the Marine Resiliency Study. Independent effects of CT history, number and type of CT on outcomes were analyzed using hierarchical multivariate logistic regression models. Our results suggested dose-dependent negative effect of an increasing number of trauma types of CT on depression, PTSD and HRQoL. Experience of single CT type demonstrated overall weak effects, while history of multiple CT types distinctively increased the likelihood of adult PTSD symptomology (OR: 3.1, 95% CI: 1.5-6.2), poor mental (OR: 2.3, 95% CI: 1.7-3.1) and physical HRQoL (OR: 1.4, 95% CI: 1.1-1.9). Risk for depression symptoms was similar for both single and multiple CT (OR: 2.2, 95% CI: 1.3-3.8 and OR: 2.1, 95% CI: 1.2-3.5 respectively). CT history had no effects on current tobacco use and alcohol abuse. Our study thus provides evidence for substantial additive effect of different CT types on adult mental and physical health with increasing levels of exposure.

There has been a paucity of research linking intermittent explosive disorder (IED) to trauma and posttraumatic stress responses, despite evidence that trauma is strongly associated with anger reactions. The present study investigated the relationship between IED and a number of trauma-related factors, including trauma dosage, timing of first trauma, and posttraumatic stress disorder (PTSD). Participants were 4844 trauma-exposed and 731 non trauma-exposed adults who took part in the National Comorbidity Survey-Replication (NCS-R). Findings indicated that IED was associated with greater trauma exposure, PTSD and generalized anxiety disorder (GAD) diagnosis, and first exposure to traumatic events in childhood. Exploratory analyses investigating the link between IED and age at first trauma exposure across trauma types suggested that IED is related to childhood exposure to interpersonal traumatic events. These findings are discussed in the context of developmental trauma and cycles of violence models.

This is a retrospective review to determine demographics, presentation and injury characteristics of trauma deaths at Howard University Hospital over an 1-year period (1994-2005) and to make recommendations for education and prevention in the community based on our findings. Data was obtained from the Howard University Hospital trauma registry. From the study period 1994-2005, there was a total of 365 trauma deaths. The injuries sustained were mainly intentional, which accounted for almost 75% of cases--the majority of deaths being due to penetrating injuries. There was an almost two-fold increase in trauma deaths on Saturdays compared to the rest of the week. The demographics of our study population were similar to those reported in the trauma literature. These were younger patients and predominantly male. Unique to our population was the overwhelming predominance of African-American patients (90%). With these unique features, injury prevention would be better served focusing on social and community prevention and education rather than the usual methods of blunt-trauma prevention--e.g., pedestrian- and motor-vehicle-oriented policies, which may be more beneficial in other trauma systems.

Blunt and penetrating cardiovascular (CV) injuries are associated with a high morbidity and mortality. Rapid detection of these injuries in trauma is critical for patient survival. The advent of multi-detector computed tomography (MDCT) has led to increased detection of CV injuries during rapid comprehensive scanning of stabilized major trauma patients. MDCT has the ability to acquire images with a higher temporal and spatial resolution, as well as the capability to create multiplanar reformats. This pictorial review illustrates several common and life-threatening traumatic CV injuries from a regional trauma center.

A numerical study was conducted to investigate the effects of blunt leading edges on the viscous flow field around a hypersonic vehicle such as the proposed National Aero-Space Plane. Attention is focused on two specific regions of the flow field. In the first region, effects of nose bluntness on the forebody flow field are investigated. The second region of the flow considered is around the leading edges of the scramjet inlet. In this region, the interaction of the forebody shock with the shock produced by the blunt leading edges of the inlet compression surfaces is analyzed. Analysis of these flow regions is required to accurately predict the overall flow field as well as to get necessary information on localized zones of high pressure and intense heating. The results for the forebody flow field are discussed first, followed by the results for the shock interaction in the inlet leading edge region.

A group of 191 cases of emergency tube thoracostomy for acute trauma reviewed retrospectively from March 1993 to March 1998 is reported. Of this group 169 were men and 22 were women. Their ages ranged from 16 to 73 years. The causes were as follows: 89 cases (46%) road accident; 33 cases (17%) accidental trauma; 33 cases (17%) someone else violence (assault, gunshot or stab wound); 15 cases (8%) work accident; 11 cases (6%) domestic accident and 5 cases (3%) iatrogenic trauma. In 32 patients a diagnosis of pneumothorax was made (2 tension, 11 for penetrating chest injuries, 19 after blunt trauma). In 2 cases of tension pneumothorax and in 3 cases of open pneumothorax a chest tube (24-28 Fr) in the third space in the mid-clavicular line was introduced. In the other patients it was decided to place a chest tube in the mid-axillary line in the fifth intercostal space to drain pneumothorax. Only in 7 cases suction was necessary. Fifty-four hemothorax (3 bilateral) were treated in 11 cases using thoracentesis, while the remaining cases were treated using the insertion of multiple drainage holes in the intercostal space (fifth in the mid-axillary line directed inferiorly and posteriorly). One hundred and three were the cases of hemopneumothorax: 24 of them received 2 chest tubes, the first (20-26 Fr) apically in the second intercostal space in the mid-clavicular line, the second (32-38 Fr) in the fifth intercostal space in the mid-axillary line. All the other cases were treated using a single thoracostomy. In 14 cases suction was applied. Two cases of chylothorax resolved by a large tube positioned in the chest (fifth intercostal space in the mid-axillary line) with a constant negative pressure were also observed. Duration of tube drainage ranged from 4 and 18 days, with an average of 11 days. Five infections of thoracostomy site and 1 empyema resolved by rethoracotomy were observed. Moreover, there were 3 complications: 2 subcutaneous placements and 1 little laceration

Number of deaths related with injuries suffered as a result of experienced traumas is increasing. Penetrating traumas of the facial skeleton occur relatively rarely and much more often concern rather children than adults. Epidemiology relating this kind of trauma differs depending on the region of the world. In Poland, gunshot injuries as well as traumas caused by explosions of firecrackers or fireworks amount only to a slight percentage among all facial skeleton traumas, and the most common reason for penetrating traumas lies in accidents or assault with the use of sharp, narrow and long objects that easily enter bones of the facial skeleton. The present study reported the case of 50-year-old man who suffered from trauma of the facial skeleton, which resulted from foreign body (pickaxe) penetration into the subtemporal area, zygomatic arch and the right orbital cavity. The surgical treatment method and final outcome was presented and discussed.

Purpose Patients suffering from severe blunt abdominal trauma are challenging because of their need for accurate diagnostic imaging and fast therapeutic action. Whole-body computed tomography (WBCT) is highly sensitive and represents the gold standard in the trauma room diagnostic setting. The aim of our study was to investigate the impact and therapy relevance of abdominal follow-up sonography (AFS) as part of the tertiary trauma survey (TTS) in patients without abdominal parenchymal organ lesions or free abdominal fluid in initial WBCT. Materials and Methods All adult patients without abdominal parenchymal organ lesions or free intraabdominal fluid in the initial WBCT examination, who received AFS within 24 hours after trauma, were included in this retrospective analysis between January 2008 and December 2011. Results 316 patients were analyzed (ISS 10 ± 8, NISS 13 ± 11) according to the inclusion criteria. Overall, only small amounts of free intraabdominal fluid were detected in AFS in 3 patients (0.9 %) and remained without therapeutic consequence. None of the patients died due to intraabdominal bleeding. Conclusion AFS as part of the TTS did not show additional benefits and had no impact on further treatment in patients without abdominal parenchymal organ lesions or free intraabdominal fluid in the initial WBCT examination. We conclude that AFS is not routinely required but should be performed if indicated on a clinical or laboratory basis because of its fast and less invasive character. Key points · Seriously injured patients are challenging for medical imaging and treatment.. · Whole-body computed tomography is known for its high accuracy in trauma patients.. · Nonetheless, missed injuries are a major challenge in trauma patients.. · Therefore, follow-up ultrasound is often performed within the tertiary trauma survey.. · Follow-up ultrasound in patients with an inconspicuous abdominal computed tomography scan did not show any

The bridging procedures discussed provide an accurate engineering method for predicting rarefied transitional aerodynamics of spherically-blunted cone entry vehicles. The single-point procedure offers a way to improve the bridging procedures while minimizing the computational effort. However, the accuracy of these procedures ultimately depends on accurate knowledge of the aerodynamics in the free-molecular and continuum limits. The excellent agreement shown for DSMC predictions and bridging relations with the Viking flight data in transitional regime enhance the coincidence in these procedures.

Institutional review boards (IRBs) have expressed concerns that certain individuals or groups, such as participants who are younger, ethnic minorities, or who have certain psychological or personality traits, may be particularly distressed when participating in "sensitive topics" research. This study examined the effects of several demographic and individual difference factors (i.e., age, sex, ethnicity, religiosity, Big Five personality traits, and baseline psychological distress levels) on reactions to participation in sensitive topics research. Participants were 504 undergraduates who completed an extensive battery of either trauma/sex questionnaires or cognitive tests and rated their positive and negative emotional reactions and the perceived benefits and mental costs of participating. They also compared research participation to normal life stressors. Our findings indicated that individual difference and demographic risk factors do not increase participant distress after participating in sex/trauma research over and above that experienced after participating in traditionally minimal-risk cognitive tasks. Participants generally found research participation less distressing than normal life stressors and even enjoyable.

The assessment of fractures is a key issue in forensic anthropology; however, very few studies deal with the features of fractures due to explosion in comparison with other traumatic injuries. This study focuses on fractures resulting from blast trauma and two types of blunt force trauma (manual compression and running over), applied to corpses of pigs; 163 osteons were examined within forty fractures by the transmission light microscopy. Blast lesions showed a higher percentage of fracture lines through the Haversian canal, whereas in other types of trauma, the fractures went across the inner lamellae. Significant differences between samples hit by blast energy and those runover or manually compressed were observed (p<0.05). The frequency of pattern A is significantly higher in exploded bones than in runover and compressed. Microscopic analysis of the fracture line may provide information about the type of trauma, especially for what concerns blast trauma.

In this chapter recent activity in real-gas database definition and code validation will be summarized. In the Phase I report of the Working Group (WG) 181, aerothermodynamic problems were classified, for purpose of discussion, into seven types: aerodynamic parameters, viscous/shock interaction, boundary-layer transition, forebody-heating/heat-transfer, radiation and ablation, lee and base-region flow, and low-density flow. Several of these problem types were the subject of various chapters of the Phase 1 report describing real-gas effects and ground test facility issues. In this chapter some background and objectives outlined in the real-Gas effects Chapter V of the Phase 1 report will be reviewed. The results of the blunt cone test campaign developed under the auspices of the WG18 activity to study real-gas phenomena will be summarized, including the experimental and computational programs, issues and questions, and recommendations. Further, recent progress in other real-gas areas beyond the blunt cone test campaign will be discussed. Finally, a summary in which the present status of our understanding of real-gas issues will be presented.
H. Julian Allen is best known for his 'Blunt Body Theory' of aerodynamics, a design technique for alleviating the severe re-entry heating problem which was then delaying the development of ballistic missiles. His findings revolutionized the fundamental design of ballistic missle re-entry shapes. Subsequently, applied research led to applications of the 'blunt' shape to ballistic missles and spacecraft which were intended to re-enter the Earth's atmosphere. This application led to the design of ablative heat shields that protected the Mercury, Gemini and Apollo astronauts as their space capsules re- entered the Earth's atmosphere. 'Harvey' Allen as he was called by most, was not only a brilliant scientist and aeronautical engineer but was also admired for his kindness, thoughtfulness and sense of humor. Among his many other accomplishments, Harvey Allen served as Center Director of the NASA Ames Research Center from 1965 to 1969. He died of a heart attack on January 29, 1977 at the age of 66.

A ruptured spleen caused by blunt abdominal injury is often treated by splenectomy. In view of the gravity of the 'postsplenectomy syndrome,' a conservative approach has been increasingly used. We present the case of a 29-year-old man with a Grade III splenic lesion for a blunt abdominal trauma after a car accident. We performed a partial splenectomy of the upper pole using GIA-Stapler. A supplemental haemostasis of the stapled line was successfully achieved by the application of FloSeal matrix haemostatic agent. The splenic remnant was fixed into the left-upper quadrant using human fibrin glue.

The word 'trauma' describes the disease entity resulting from physical injury. Trauma is one of the leading causes of death worldwide and deaths due to injury look set to increase. As early as the 1970s, it became evident that centralisation of resources and expertise could reduce the mortality rate from serious injury and that organisation of trauma care delivery into formal systems could improve outcome further. Internationally, trauma systems have evolved in various forms, with widespread reports of mortality and functional outcome benefits when major trauma management is delivered in this way. The management of major trauma in England is currently undergoing significant change. The London Trauma System began operating in April 2010 and others throughout England became operational this year. Similar systems exist internationally and continue to be developed. Anaesthetists have been and continue to be involved with all levels of trauma care delivery, from the provision of pre-hospital trauma and retrieval teams, through to chronic pain management and rehabilitation of patients back into society. This review examines the international development of major trauma care delivery and the components of a modern trauma system.

Refugees commonly experience traumatic events that threaten the self and close others, suggesting the possibility that they may experience overlapping symptoms of posttraumatic stress disorder (PTSD) and separation anxiety disorder (SAD). We examine this possibility among West Papua refugees (n = 230) displaced to Port Moresby, Papua New Guinea. We also examine associations between the combined PTSD-SAD construct and indices of past trauma exposure, ongoing adversity, and the psychosocial disruptions caused by mass conflict and displacement. We applied culturally adapted interview modules to assess symptoms of PTSD, SAD, traumatic events (TEs), ongoing adversity, and 5 psychosocial dimensions. Latent class analysis identified a PTSD class (23%), a posttraumatic (PT) SAD class (22%), and a low-symptom class (55%). Compared with the low-symptom class, both the PTSD and PT-SAD classes endorsed higher levels of exposure to all domains of TEs (conflict-related trauma, witnessing murder, childhood related adversities, traumatic losses, and health stress) and ongoing adversity (access to health care, displacement/separation, safety in the community, and access to basic needs), but the 2 comorbid groups did not differ on these indices. The PT-SAD class alone scored higher than the low-symptom reference class in relation to disruptions to the psychosocial domains (safety/security, bonds/network, access to justice, roles/identities, existential meaning) and higher than the PTSD class on safety/security, justice and roles/identities. Our findings suggest that the PT-SAD pattern may represent a response to the most severe forms of psychosocial disruptions of mass conflict among refugees. A focus on separation anxiety may enhance psychotherapies designed to treat PTSD in refugees. (PsycINFO Database Record

Blunt abdominal aortic injury is an uncommon traumatic finding. In the past, treatment options have traditionally consisted of open operative repair; however, the development of endovascular surgery has created new interventional possibilities. This case is presented to demonstrate the applications of endovascular abdominal aortic repair for a blunt traumatic injury. PMID:23730142

Context: Sport-related spleen and liver injuries pose a challenge for the physician. Although rare, these injuries can have serious and even life-threatening outcomes if not accurately diagnosed and managed in a timely fashion. Currently, there are no evidence-based guidelines on duration and intensity of restricted activity and return to play after spleen and liver injury. In addition, there is controversy on follow-up imaging after injury. Evidence Acquisition: PubMed was searched using the terms splenic or spleen and trauma and hepatic or liver and trauma from 1980 to 2013. The citations from sentinel papers were also reviewed. Study Design: Clinical review. Level of Evidence: Level 3. Results: Ultrasound is ideal in the unstable athlete. Nonoperative management of blunt splenic and hepatic injuries is recommended for hemodynamically stable patients regardless of injury grade, patient age, or presence of associated injuries. Follow-up imaging is not routinely recommended unless clinically indicated. Athletes may engage in light activity for the first 3 months after injury and then gradual return to unrestricted activity as tolerated. High-level athletes may choose splenectomy or serial imaging for faster return to play. Conclusion: Intravenous contrast-enhanced computed tomography is the diagnostic imaging modality of choice in stable athletes with blunt abdominal trauma. Strength-of-Recommendation Taxonomy: C.

A review of splenic injuries at Cincinnati Children's Hospital Medical Center from July 1978 to June 1980 revealed this form of injury in 29 patients. Treatment without surgery was successful in 21 patients. Seven patients required operation. One patient died shortly after admission of severe associated injuries. All patients admitted with blunt abdominal trauma were initially treated conservatively. If the clinical state improved, after transfusions if necessary, or remained stable and there were no objective signs of further blood loss, conservative therapy was continued. Liver-spleen scans were obtained on an urgent basis to confirm the diagnosis of splenic injury in patients who did not undergo surgery. No complications of treatment without surgery were recognized. The satisfactory outcome in these patients suggests that there is a place for treatment without surgery in some children with splenic injury.

Recent data suggests that a history of childhood maltreatment is associated with reductions in hippocampal volume in healthy adults. Because this association is also evident in adults with psychiatric illness, it has been suggested that reductions in hippocampal volume associated with childhood maltreatment may be a risk factor for psychiatric illness. Such an interpretation suggests that healthy adults with a history of childhood maltreatment are more resilient to the effects of maltreatment. Current models of resilience suggest, however, that resiliency should be measured across multiple domains of functioning. The present study sought to investigate childhood maltreatment in relationship to hippocampal volumes in healthy adults and to address the question of whether the putative resiliency extends to other domains of functioning. Sixty-seven healthy Caucasian adults were assessed for a history of childhood emotional abuse, emotional neglect and physical abuse and received high resolution structural MR imaging scans. Participants with and without histories of abuse or neglect were compared on measures of total hippocampal volume, general cognitive ability and subclinical psychopathology. Our results suggest that childhood emotional abuse is associated with reduced hippocampus volume in males, but not in females. However, emotional abuse was associated with higher levels of subclinical psychopathology in both males and females. These data suggest that while females may be more resilient to the neurological effects of childhood maltreatment, they are not more resilient to the psychiatric symptoms associated with childhood maltreatment. Further research is needed to elucidate the mechanisms involved in these different levels of resilience.

The study of skin and bone lesions may give information concerning type and manner of production, but in burnt material modification of tissues by the high temperatures may considerably change the morphological characteristics of the lesions. This study aims at pointing out the effects of burning head of pigs with several types of lesions (blunt trauma, sharp force, and gunshot lesions) on soft tissues and bones, both from a morphological and chemical point of view. Results show that the charring process does not completely destroy signs of lesions on bones, which can often be recovered by cleaning bone surface from charred soft-tissue residues. Furthermore, neutron activation analysis test proved that antimony may be detectable also on gunshot entry wounds at the final stages of charring process.

Patients with thoracic trauma constitute one third of all the trauma cases. Of traumatic patients, 20-25 % die because of thoracic trauma. Our aim was to compare our clinical experience and the results with the related literature. Four hundred thirty-three patients, who underwent surgical interventions due to thoracic trauma, were evaluated. The latest form of treatment applied were taken as the criteria for the quantitative detection of patients. Continuous variables were expressed as mean ± standard deviation, while categorical variables were explained as number and percentage. The significance of the analysis results was evaluated using Fisher's exact test. p values <0.05 were considered as significant. Penetrating injuries were found in 258 (59 %) of the patients, and blunt trauma was identified in 175 (41 %). Depending on the trauma, pneumothorax was discovered in 130 patients (30.02 %), hemothorax in 117 (27.02 %), hemopneumothorax in 61 (14.08 %), pulmonary contusion in 110 (45 %), pneumomediastinum in 14 (3.23 %), and pericardial tamponade in 1 patient (0.23 %). It was demonstrated that 385 of 433 patients examined in the study underwent tube thoracostomy, 41 were treated with thoracotomy, while 6 of them underwent video-assisted thoracoscopic surgery (VATS), and 1 underwent sternotomy. No correlation was observed between mortality, morbidity, and gender and type of trauma and location of trauma (p > 0.05). However, statistically significant correlation was found between mortaxlity, morbidity, and the presence of concomitant injuries, the duration between injury and admission being more than 1 h (p < 0.05). Urgent intervention, early diagnosis, and fast transport are vital for patients with thoracic injuries.

The aim of this study is to develop a reliable and efficient design tool that can be used in hypersonic flows. The flow analysis is based on the axisymmetric Euler/Navier-Stokes and finite-rate chemical reaction equations. The equations are coupled simultaneously and solved implicitly using Newton's method. The Jacobian matrix is evaluated analytically. A gradient-based numerical optimization is used. The adjoint method is utilized for sensitivity calculations. The objective of the design is to generate a hypersonic blunt geometry that produces the minimum drag with low aerodynamic heating. Bezier curves are used for geometry parameterization. The performances of the design optimization method are demonstrated for different hypersonic flow conditions.

The effect of hyperbaric oxygenation (HBO2) on survival during the early phase of severe blunt chest injury (BChI) has not been elucidated. Our aim was to investigate this effect on human victims of BChI. We monitored cardiac index (CI), stroke volume index (SVI), PaO2 and PaO2/FiO2 in 18 victims treated conventionally, and 8 victims treated under combined conventional and HBO2 treatment. Out of the 18 victims, 4 survived (Group A) and 14 died (Group B). Another 8 victims, in Group C, received HBO, and all survived. Human victims showed marked reductions in all cardiorespiratory values during the first 24 h. Group B persistently tended towards a decrease in SVI, PaO2/FiO2 and PaO2, eventually reaching fatal levels. The survivors developed a cardiorespiratory function characterized by a tendency towards recovery of all monitored parameters, more notable in Group C, which showed an earlier and more significant normalization vs. Group A (P<0.01). Our clinical data suggest that the earliest possible HBO2 treatment after severe blunt trauma can significantly enhance victims' survival.

ehind Armor Blunt Trauma (BABT) is a persistent concern for both the military and civil law enforcement. Although personal protective equipment (PPE), including soft and hard body armor, mitigates penetrating injuries from ballistic threats, the impact generates a backface deformation which creates a high-rate blunt impact to the body and potential internal injury (i.e., BABT). A critical need exists to understand the mechanics of the human response and subsequently evaluate the efficacy of current and proposed PPE in mitigating BABT injury risk. Current human surrogate test platforms lack anatomical fidelity or instrumentation for capturing the dynamic transfer of energy during the event. Therefore, we have developed and tested a Human Surrogate Torso Model (HSTM) composed of biosimulants representing soft tissues and skeleton of the human torso. A matrix of pressure transducers were embedded in the soft tissue and a custom displacement sensor was mounted to the skeletal structure to measure sternum displacement. A series of non-penetrating, high energy ballistic tests were performed with the HSTM. Results indicate that both sternum displacement and internal localized pressure are sensitive to impact energy and location. These data provide a spatial and temporal comparison to the current standard (static clay measurements) and a method for evaluating the applicability of thoracic injury metrics, including the Viscous Criterion, for BABT. The HSTM provides an advanced, biomechanically relevant test platform for determining the thoracic response to dynamic loading events due to non-penetrating ballistic impacts.

We report on 2 cases of hyperextension/valgus elbow injuries in two adult male national team water polo goalkeepers. Both were healthy and had never sustained any major injuries of the elbow. Mechanism and type of injury in both of them was identical. Different medical treatment protocols of these injuries possibly have led to different outcomes, with one of them developing osteochondritis dissecans (OCD). Inadequate medical treatment of acute impact elbow injuries could lead to osteochondritis disecans of the elbow in top-level adult male water polo goalkeepers.

BACKGROUND: Modern civilization and the sharp rise in living standards have led to dramatic changes in trauma pattern in Saudi Arabia. This study aimed to describe the different patterns of injuries of patients attending the Emergency Department of Jazan General Hospital (JGH) in the southwest corner of Saudi Arabia. METHODS: A total number of 1 050 patients were enrolled in the study. A pre-organized data sheet was prepared for each patient attended the Emergency Department of JGH from February 2012 to January 2013. It contains data about socio-demographics, trauma data, clinical evaluation results, investigations as well as treatment strategies. RESULTS: The mean age of the patients was 25.3±16.8 years. Most (45.1%) of the patients were at age of 18–30 years. Males (64.3%) were affected by trauma more common than females. More than half (60.6%) of the patients were from urban areas. The commonest kind of injury was minor injury (60%), followed by blunt trauma (30.9%) and then penetrating trauma (9.1%). The mean time from the incident to arrival at hospital was 41.3±79.8 minutes. The majority (48.2%) of the patients were discharged after management of trivial trauma, whereas 2.3% were admitted to ICU, 7.7% transferred to inpatient wards, and 17.7% observed and subsequently discharged. The mortality rate of the patients was 2.6%. CONCLUSION: Trauma is a major health problem, especially in the young population in Saudi Arabia. Blunt trauma is more frequent than penetrating trauma, with road traffic accidents accounting for the majority. PMID:25802567

Background: Operative intervention for thoracic trauma typically requires thoracotomy. We hypothesized that thoracoscopy may be safely and effectively utilized for the acute management of thoracic injuries. Materials and Methods: The Trauma Registry of a Level I trauma center was queried from 1999 through 2010 for all video-assisted thoracic procedures within 24 h of admission. Data collected included initial vital signs, operative indication, intraoperative course, and postoperative outcome. Results: Twenty-three patients met inclusion criteria: 3 (13%) following blunt injury and 20 (87%) after penetrating trauma. Indications for urgent thoracoscopy included diaphragmatic/esophageal injury, retained hemothorax, ongoing hemorrhage, and open/persistent pneumothorax. No conversions to thoracotomy were required and no patient required re-operation. Mean postoperative chest tube duration was 2.9 days and mean length of stay was 5.6 days. Conclusion: Video-assisted thoracoscopic surgery is safe and effective for managing thoracic trauma in hemodynamically stable patients within the first 24 h post-injury. PMID:23723618

African American men (AAM) who are exposed to trauma and adversity during their early life are at greater risk for poor health over their lifespan. Exposure to adversity during critical developmental windows may embed an epigenetic signature that alters expression of genes that regulate stress response systems, including those genes that regulate the inflammatory response to stress. Such an epigenetic signature may increase risk for diseases exacerbated by inflammation, and may contribute to health disparity. The purpose of this study was to evaluate the extent to which exposure to early life adversity influences the psychological, cortisol, and proinflammatory response to acute stress (Trier Social Stress Test - TSST) in emerging adult AAM, ages 18-25years (N=34). Hierarchical linear modeling was used to examine the cortisol and IL-6 pattern of response to the TSST with respect to childhood adversity factors and DNA methylation of the IL-6 promoter. Findings revealed that in response to the TSST, greater levels of childhood trauma and indirect exposure to neighborhood violence were associated with a greater TSST-induced IL-6 response, and a blunted cortisol response. Reduced methylation of the IL6 promoter was related to increased exposure to childhood trauma and greater TSST-induced IL-6 levels. These results support the concept that exposure to childhood adversity amplifies the adult proinflammatory response to stress, which is related to epigenetic signature.

Fractures of the midface pose a serious medical problem as for their complexity, frequency and their socio-economic impact. Interdisciplinary approaches and up-to-date diagnostic and surgical techniques provide favorable results in the majority of cases though. Traffic accidents are the leading cause and male adults in their thirties are affected most often. Treatment algorithms for nasal bone fractures, maxillary and zygomatic fractures are widely agreed upon whereas trauma to the frontal sinus and the orbital apex are matter of current debate. Advances in endoscopic surgery and limitations of evidence based gain of knowledge are matters that are focused on in the corresponding chapter. As for the fractures of the frontal sinus a strong tendency towards minimized approaches can be seen. Obliteration and cranialization seem to decrease in numbers. Some critical remarks in terms of high dose methylprednisolone therapy for traumatic optic nerve injury seem to be appropriate. Intraoperative cone beam radiographs and preshaped titanium mesh implants for orbital reconstruction are new techniques and essential aspects in midface traumatology. Fractures of the anterior skull base with cerebrospinal fluid leaks show very promising results in endonasal endoscopic repair. PMID:26770280

Hemothorax is common in elderly patients following blunt chest trauma. Traditionally, tube thoracostomy is the first choice for managing this complication. The goal of this study was to determine the benefits of this approach in elderly patients with and without an initial tube thoracostomy. Seventy-eight patients aged >65 years with blunt chest trauma and stable vital signs were included. All of them had more than 300 mL of hemothorax, indicating that a tube thoracostomy was necessary. The basic demographic data and clinical outcomes of patients with hemothorax who underwent direct video-assisted thoracoscopic surgery without a tube thoracostomy were compared with those who received an initial tube thoracostomy. Patients who did not receive a thoracostomy had lower posttrauma infection rates (28.6% versus 56.3%, P = 0.061) and a significantly shorter length of stay in the intensive care unit (3.13 versus 8.27, P = 0.029) and in the hospital (15.93 versus 23.17, P = 0.01) compared with those who received a thoracostomy. The clinical outcomes in the patients who received direct VATS were more favorable compared with those of the patients who did not receive direct VATS. PMID:27190987

Genitourinary system injuries generally occur due to blunt and penetrating trauma. Approximately 10% of all injuries encountered in the emergency department are related to the genitourinary system. Male genital trauma is a urological emergency because of the high risk of infection and the priority of protecting the sexual, endocrine, and reproductive functions. Blunt injuries to the penis are more often seen due to the mobility and localization of the penis than due to penetrating injuries caused by firearms or cutting instruments. We aimed to present and discuss a case involving shrapnel that became lodged in the penis of a child in a war zone. After 2 weeks of medical treatment, the patient underwent surgery. Surgery includes primary repair to the penis and urethra. PMID:28149826

Rationale: Acute lung injury is a common complication after severe trauma, which predisposes patients to multiple organ failure. This syndrome largely accounts for the late mortality that arises and despite many theories, the pathological mechanism is not fully understood. Discovery of histone-induced toxicity in mice presents a new dimension for elucidating the underlying pathophysiology. Objectives: To investigate the pathological roles of circulating histones in trauma-induced lung injury. Methods: Circulating histone levels in patients with severe trauma were determined and correlated with respiratory failure and Sequential Organ Failure Assessment (SOFA) scores. Their cause–effect relationship was studied using cells and mouse models. Measurements and Main Results: In a cohort of 52 patients with severe nonthoracic blunt trauma, circulating histones surged immediately after trauma to levels that were toxic to cultured endothelial cells. The high levels were significantly associated with the incidence of acute lung injury and SOFA scores, as well as markers of endothelial damage and coagulation activation. In in vitro systems, histones damaged endothelial cells, stimulated cytokine release, and induced neutrophil extracellular trap formation and myeloperoxidase release. Cellular toxicity resulted from their direct membrane interaction and resultant calcium influx. In mouse models, cytokines and markers for endothelial damage and coagulation activation significantly increased immediately after trauma or histone infusion. Pathological examinations showed that lungs were the predominantly affected organ with edema, hemorrhage, microvascular thrombosis, and neutrophil congestion. An anti-histone antibody could reduce these changes and protect mice from histone-induced lethality. Conclusions: This study elucidates a new mechanism for acute lung injury after severe trauma and proposes that circulating histones are viable therapeutic targets for improving survival

Purpose: To study the epidemiology and clinical profile of victims of ocular trauma in an urban slum population. Materials and Methods: This cross-sectional study, conducted on 500 families each in three randomly selected urban slums in Delhi, collected demographic data for all members of these families, and clinical data for all those who suffered ocular trauma at any time, that required medical attention. Data was managed on SPSS 11.0. Results: Of 6704 participants interviewed, 163 episodes of ocular trauma were reported by 158 participants (prevalence = 2.4%, confidence interval = 2.0 to 2.7) Mean age at trauma was 24.2 years. The association between the age of participants and the history of ocular trauma was significant (P < 0.001), when adjusted for sex, education and occupation. Males were significantly more affected. Blunt trauma was the commonest mode of injury (41.7%). Blindness resulted in 11.4% of injured eyes ( P = 0.028). Of 6704 participants, 1567 (23.4%) were illiterate, and no association was seen between education status and trauma, when adjusted for sex and age at injury. A significant association was noted between ocular trauma and workplace (Chi-square = 43.80, P < 0.001), and between blindness and place (Chi-square = 9.98, P = 0.041) and source (Chi-square = 10.88, P = 0.028) of ocular trauma. No association was found between visual outcome and the time interval between trauma and first consultation (Chi-square = 0.50, P = 0.78), between receiving treatment and the best corrected visual acuity (Chi-square = 0.81, P = 0.81), and between the person consulted and blinding ocular trauma (Chi-square = 1.88, P = 0.170). Conclusion: A significant burden of ocular trauma in the community requires that its prevention and early management be a public health priority. PMID:18579991

Point-of-care ultrasound is well suited for use in the emergency setting for assessment of the trauma patient. Currently, portable ultrasound machines with high-resolution imaging capability allow trauma patients to be imaged in the pre-hospital setting, emergency departments and operating theatres. In major trauma, ultrasound is used to diagnose life-threatening conditions and to prioritise and guide appropriate interventions. Assessment of the basic haemodynamic state is a very important part of ultrasound use in trauma, but is discussed in more detail elsewhere. Focussed assessment with sonography for Trauma (FAST) rapidly assesses for haemoperitoneum and haemopericardium, and the Extended FAST examination (EFAST) explores for haemothorax, pneumothorax and intravascular filling status. In regional trauma, ultrasound can be used to detect fractures, many vascular injuries, musculoskeletal injuries, testicular injuries and can assess foetal viability in pregnant trauma patients. Ultrasound can also be used at the bedside to guide procedures in trauma, including nerve blocks and vascular access. Importantly, these examinations are being performed by the treating physician in real time, allowing for immediate changes to management of the patient. Controversy remains in determining the best training to ensure competence in this user-dependent imaging modality.

Paleopathological assessment of the late Middle Pleistocene archaic human cranium from Maba, South China, has documented a right frontal squamous exocranially concave and ridged lesion with endocranial protrusion. Differential diagnosis indicates that it resulted from localized blunt force trauma, due to an accident or, more probably, interhuman aggression. As such it joins a small sample of pre-last glacial maximum Pleistocene human remains with probable evidence of humanly induced trauma. Its remodeled condition also indicates survival of a serious pathological condition, a circumstance that is increasingly documented for archaic and modern Homo through the Pleistocene. PMID:22106311

Partial optic nerve avulsion (ONA) secondary to finger gouging is an uncommon but devastating injury. A 21-year-old man who had an acute vision loss after accidentally getting poked by himself in his right eye when he fell down during jogging is reported. The patient was diagnosed with partial ONA. Magnetic resonance imaging revealed intact optic nerve. Optical coherence tomography (OCT) revealed deep cavity at the inferior-temporal half of the optic disc. Retinal nerve fiber layer thickness was also thin at the inferior quadrant with circumpapillary OCT scan. Visual field test and electrophysiological tests showed functional abnormality compatible with optic nerve lesion. Diagnostic tools for anatomical and functional evaluation may reveal the course of this injury. PMID:20952839

A 67-year-old man suffered a traffic accident and was transferred to an emergency hospital close to the scene. He was diagnosed to have bilateral pneumohemothorax with a lung contusion, an anterior fracture dislocation of the C6-vertebra and a cervical cord injury at the level of C7. On the 48th day, massive hemoptysis was suddenly recognized. He was transferred in a state of shock to our hospital to undergo hemostasis for the bleeding. On the day of admission, a selective arteriogram showed extravasation from the left bronchial artery, for which embolization was carried out using Gelfoam. In spite of this treatment, his hemoptysis continued. On the next day, a selective left internal mammary arteriogram showed an arteriovenous fistula between the left internal mammary artery and the left pulmonary vein without any apparent extravasation. The arteriovenous fistula was successfully embolized using platinum fiber coils. The patient no longer demonstrated any hemoptysis after embolization.

La rotura traqueal tras una contusión es rara, aunque potencialmente mortal. En general, se recomienda el tratamiento quirúrgico para la rotura traqueal, aunque también se ha informado recientemente el abordaje conservador en los pacientes con signos vitales y parámetros respiratorios estables. El objetivo de este estudio es informar sobre un caso de rotura traqueal tras una contusión en el cuello producto de un accidente de bicicleta que se trató de manera conservadora.
Introduction Crush asphyxia is different from positional asphyxia, as respiratory compromise in the latter is caused by splinting of the chest and/or diaphragm, thus preventing normal chest expansion. There are only a few cases or small case series of crush asphyxia in the literature, reporting usually poor outcomes. Case presentation We present the case of a 44-year-old Caucasian man who developed traumatic asphyxia with severe thoracic injury and mild brain edema after being crushed under heavy auto vehicle mechanical parts. He remained unconscious for an unknown time. The treatment included oropharyngeal intubation and mechanical ventilation, bilateral chest tube thoracostomies, treatment of brain edema and other supportive measures. Our patient’s outcome was good. Traumatic asphyxia is generally under-reported and most authors apply supportive measures, while the final outcome seems to be dependent on the length of time of the chest compression and on the associated injuries. Conclusion Treatment for traumatic asphyxia is mainly supportive with special attention to the re-establishment of adequate oxygenation and perfusion; treatment of the concomitant injuries might also affect the final outcome.

Contact sports have long been a part of human existence. The two earliest recorded organized contact games, both of which still exist, include Royal Shrovetide Football played since the 12th century in England and Caid played since 1308 AD in Ireland. Rugby is the premier contact sport played throughout the world with the very popular derivative American football being the premier contact sport of the North American continent. American football in the USA has on average 1,205,037 players at the high school and collegiate level per year while rugby in the USA boasts a playing enrollment of 457,983 at all levels. Recent media have highlighted injury in the context of competitive contact sports including their long-term sequelae such as chronic traumatic encephalopathy (CTE) that had previously been underappreciated. Blunt cerebrovascular injury (BCVI) has become a recognized injury pattern for trauma; however, a paucity of data regarding this injury can be found in the sports trauma literature.

Bongs and blunts constitute significant elements of marijuana consumption in the United States, especially among youth. The author draws upon ethnographic methods to provide rich descriptions of these practices amongst a network of suburban marijuana users. The author first provides a description of bong use in a suburban home prior to detailing the same youth network engaging in the process of rolling and smoking a blunt in a public environment. Ultimately, the author examines and contrasts these two features of American marijuana consumption.

In much of contemporary culture, "trauma" signifies not so much terrible experience as a particular context for understanding and responding to a terrible experience. In therapy, in the media, and in international interventions, the traumatized are seen not simply as people who suffer and so are deserving of concern and aid; they are seen also as people who suffer for us, who are given special dispensation. They are treated with awe if they tell a certain kind of trauma story, and are ignored or vilified if they tell another. Trauma has become not simply a story of pain and its treatment, but a host of sub-stories involving the commodification of altruism, the justification of violence and revenge, the entry point into "true experience," and the place where voyeurism and witnessing intersect. Trauma is today the stuff not only of suffering but of fantasy. Historically, trauma theory and treatment have shown a tension, exemplified in the writings of Freud and Janet, between those who view trauma as formative and those who view it as exceptional. The latter view, that trauma confers exceptional status deserving of special privilege, has gained ground in recent years and has helped to shape the way charitable dollars are distributed, how the traumatized are presented in the media, how governments justify and carry out international responses to trauma, and how therapists attend to their traumatized patients. This response to trauma reflects an underlying, unarticulated belief system derived from narcissism; indeed, trauma has increasingly become the venue, in society and in treatment, where narcissism is permitted to prevail.

There is a large consensus indicating that childhood trauma is significantly involved in the development of depression. The aim of this study was to examine the prevalence of retrospectively recalled childhood trauma in chronically depressed patients and to investigate a more specific relationship between trauma type and depression. We further asked for the influence of multiple experiences of childhood trauma on the vulnerability to a chronic course of depression in adulthood. 349 chronically depressed patients of the German LAC Depression Study completed the Childhood Trauma Questionnaire, a self-report measure of traumatic experiences in childhood. 75.6% of the chronically depressed patients reported clinically significant histories of childhood trauma. 37% of the chronically depressed patients reported multiple childhood traumatization. Experiences of multiple trauma also led to significantly more severe depressive symptoms. Stepwise multiple regression analysis suggested that childhood emotional abuse and sexual abuse were significantly associated with a higher symptom severity in chronically depressed adults. Yet, expanding the regression model for multiple exposures showed that multiplicity was the only remaining significant predictor for symptom severity in chronically depressed patients. Clinical implications suggest a precise assessment of childhood trauma in chronically depressed patients with a focus on emotional abuse, sexual abuse, and multiple exposures to childhood trauma. This trial is registered with registration number ISRCTN91956346. PMID:26693349

Introduction Accurate field triage of critically injured patients to trauma centers is vital for improving survival. We sought to estimate the national degree of undertriage of trauma patients who die in emergency departments (EDs) by evaluating the frequency and characteristics associated with triage to non-trauma centers. Methods This was a retrospective cross-sectional analysis of adult ED trauma deaths in the 2010 National Emergency Department Sample (NEDS). The primary outcome was appropriate triage to a trauma center (Level I, II or III) or undertriage to a non-trauma center. We subsequently focused on urban areas given improved access to trauma centers. We evaluated the associations of patient demographics, hospital region and mechanism of injury with triage to a trauma versus non-trauma center using multivariable logistic regression. Results We analyzed 3,971 included visits, representing 18,464 adult ED trauma-related deaths nationally. Of all trauma deaths, nearly half (44.5%, 95% CI [43.0–46.0]) of patients were triaged to non-trauma centers. In a subgroup analysis, over a third of urban ED visits (35.6%, 95% CI [34.1–37.1]) and most rural ED visits (86.4%, 95% CI [81.5–90.1]) were triaged to non-trauma centers. In urban EDs, female patients were less likely to be triaged to trauma centers versus non-trauma centers (adjusted odds ratio [OR] 0.83, 95% CI [0.70–0.99]). Highest median household income zip codes (≥$67,000) were less likely to be triaged to trauma centers than lowest median income ($1–40,999) (OR 0.54, 95% CI [0.43–0.69]). Compared to motor vehicle trauma, firearm trauma had similar odds of being triaged to a trauma center (OR 0.90, 95% CI [0.71–1.14]); however, falls were less likely to be triaged to a trauma center (OR 0.50, 95 %CI [0.38–0.66]). Conclusion We found that nearly half of all trauma patients nationally and one-third of urban trauma patients, who died in the ED, were triaged to non-trauma centers, and thus

Receptivity and stability of hypersonic boundary layers are numerically investigated for boundary layer flows over a 5-degree straight cone at a free-stream Mach number of 6.0. To compute the shock and the interaction of shock with the instability waves, we solve the Navier-Stokes equations in axisymmetric coordinates. The governing equations are solved using the 5th-order accurate weighted essentially non-oscillatory (WENO) scheme for space discretization and using third-order total-variation-diminishing (TVD) Runge-Kutta scheme for time integration. After the mean flow field is computed, disturbances are introduced at the upstream end of the computational domain. Generation of instability waves from leading edge region and receptivity of boundary layer to slow acoustic waves are investigated. Computations are performed for a cone with nose radii of 0.001, 0.05 and 0.10 inches that give Reynolds numbers based on the nose radii ranging from 650 to 130,000. The linear stability results showed that the bluntness has a strong stabilizing effect on the stability of axisymmetric boundary layers. The transition Reynolds number for a cone with the nose Reynolds number of 65,000 is increased by a factor of 1.82 compared to that for a sharp cone. The receptivity coefficient for a sharp cone is about 4.23 and it is very small, approx.10(exp -3), for large bluntness.

Current research suggests that interpersonal trauma has an impact on insecure attachment and anxiety. Some research further suggests that attachment may play a mediating role between traumatic events and psychopathology. The purpose of this study was to examine the relationship between the experience of interpersonal trauma, attachment anxiety, attachment avoidance and clinical anxiety severity among adult psychiatric inpatients who reported having experienced interpersonal trauma after the age of 16. It was hypothesized that attachment anxiety and attachment avoidance would mediate the relationship between interpersonal trauma and clinical anxiety level. This study used archival data on 414 adult psychiatric inpatients in a large city in the Southwest U.S. Results suggest that interpersonal trauma was correlated to attachment avoidance but not to attachment anxiety and that attachment avoidance partially mediated the relation of interpersonal trauma to anxiety. The attachment framework appositely explains how a negative model of other contributes to the relation between experiences of interpersonal trauma and anxiety in adulthood.

The psychiatric sequelae associated with childhood experience(s) of trauma is complex and distinguishable from that of adult trauma exposure. Categories of impairment associated with experiences of early trauma include internalizing and externalizing emotional and behavioral problems, posttraumatic stress symptomatology, and dissociation. The present study assessed the relationship between the type of trauma experience (i.e., non-interpersonal or interpersonal) and the manifestation of a wide range of psychiatric symptomatology using prospective longitudinal data from a community sample of ethnically diverse children and adolescents (N=1676; ages 4-18). The study also examined the relationship between different types of trauma experiences (e.g., direct, vicarious, interpersonal) and levels of various symptom domains (e.g., anxiety, posttraumatic stress, conduct problems). A number of factors relevant to the relationship between early trauma experience and subsequent impairment including temperament, socioeconomic status, sex, and age were included in the analyses. Results indicated that interpersonal traumas involving significant interpersonal proximity were associated with externalizing problems (i.e., oppositional defiant and conduct problems). Direct trauma experiences and emotionality were positively associated with almost all symptom domains. Implications for the relationship between trauma and developmental psychopathology are discussed.

Bromocriptine-induced tachycardia, persisting after adrenalectomy, is mediated by central dopamine D2 receptor stimulation through activation of the sympathetic outflow to the heart. The present study investigated the effects of malnutrition during pregnancy on bromocriptine-induced tachycardia in adult conscious rats. Malnourished rats were obtained by feeding dams a multideficient diet (providing 8% protein) during mating and pregnancy. Birth weight was significantly reduced in malnourished rats when compared to control rats born to dams fed standard commercially diet (23% protein) during mating and pregnancy. Baseline mean aortic pressure and heart rate in malnourished rats were comparable to those of well-nourished rats. Tachycardia (33+/-9 beats/min.), but not the hypotensive response to intravenous bromocriptine (150 microg/kg) was significantly reduced in malnourished rats, compared with control rats (70+/-10 beats/min.). In malnourished rats, pretreatment with intravenous domperidone (500 microg/kg) blocked the bromocriptine-induced hypotension, without affecting the tachycardia. Neither cardiac vagal (40+/-6 beats/min.) nor sympathetic tone (76+/-6 beats/min.) was significantly altered by multideficient diet-induced malnutrition (51+/-6 and 67+/-10 beats/min., respectively). In isolated perfused heart preparations from malnourished rats, positive inotropic response to isoproterenol (10-8 to 10-4 M) was not significantly different compared to that in control rats. In summary, malnutrition during foetal life blunted the bromocriptine-induced tachycardia, an effect that could be related to central dopamine D2 receptor desensitization rather than to impairment of autonomic regulation of the heart or cardiac beta-adrenoceptor desensitization.

A spleen-preserving program was implemented at the author's institution during the mid-1980s using a five-part injury-grading scale that is similar and comparable to the AAST classification. Since that time, all patients with splenic injuries admitted to the Department of Surgery at the Karl-Franzens University Hospital in Graz, a level I trauma center, have been prospectively evaluated with respect to splenic preservation. Analysis of the relation of the severity of organ injury to the use of nonoperative management showed that degree I or II injuries were treated nonoperatively, whereas degree III and IV injuries were usually treated with adhesives, partial resection, or mesh splenorrhaphy; only degree V injuries almost always required splenectomy. With increasing experience in nonoperative management of splenic injuries the initial criteria have become less rigid, and there is now a tendency to attempt it in patients who formerly would have undergone surgery.

There exists a popular belief in the causal relationship between the moon's phase and the incidence of major trauma. In this retrospective study we reviewed 1,444 trauma victims admitted to the hospital during one calendar year. Full moons were defined as three-day periods in the 29.531-day lunar cycle, with the middle day being described in the world almanac as the full moon. Victims of violence included those patients sustaining blunt assault, gunshot wounds, and stabbings. There was no statistical difference in number of trauma admissions between the full moon, 129 patients per 36 days (mean, 3.58), and nonfull moon days, 1,315 patients per 330 days (mean, 3.98). Mortality rate, 5.4% versus 10.3%; mean Injury Severity Score, 13 versus 15; and mean length of stay, ten versus 12 days, were not significantly different during the full moon and nonfull moon days. Victims of violence were admitted at a similar frequency on full moon, 16 patients per 36 days (mean, 0.444), and nonfull moon days, 183 patients per 330 days (mean, 0.555). We conclude that the belief in the deleterious effects of the full moon on major trauma is statistically unfounded.

Ghrelin, neuropeptide Y (NPY) and cholecystokinin (CCK) all have important roles in the regulation of feeding in fish and mammals. To better understand the role of the three peptides in appetite regulation in the early developmental stages of blunt snout bream (Megalobrama amblycephala), partial cDNA sequences of ghrelin, NPY and CCK genes were cloned. And then, real-time quantitative PCR and RT-PCR were used to detect and quantify the mRNA expressions of these genes from zygotes to larvae of 50 days after hatching (DAH). Ghrelin, NPY and CCK were all expressed throughout the embryonic and larval development stages, and the expression levels were higher in larval stages than in embryonic stages. Ghrelin and NPY mRNA expressions were upregulated at 1, 3, 5 DAH, while CCK mRNA expression was reduced significantly at 3 DAH. The mRNA expression levels of three genes in larvae varied significantly until 30 DAH. In adult fish, all three peptides were detected to be expressed in brain and several peripheral tissues. Ghrelin mRNA was mainly expressed in the intestine, whereas NPY and CCK mRNAs were mainly expressed in the brain. Taken together, these results indicate that ghrelin, NPY and CCK may have roles in early development and participate in the regulation of feeding of larvae in blunt snout bream and will be helpful for further investigation into feed intake regulation in adults of this species.

There is a paucity of data evaluating serum albumin on admission as a predictor of outcome in adult trauma patients. Our objectives were to evaluate whether or not hypoalbuminemia on admission is a predictor of adverse outcome in trauma patients. Prospective data was collected daily on 1023 patients over a 2-year period. Patients were stratified by serum albumin level on admission, age, gender, injury severity, and comorbid conditions. Outcome was measured by ICU and hospital length of stay, ventilator days, incidence of infection, and mortality. Student t test, chi2, and multilinear regression analysis were used to determine level of significance. Blunt injuries accounted for the majority (78%) of the admissions. The mean age of the study population was 43+/-21 years with a mean Injury Severity Score (ISS) of 21.4+/-12. The majority of patients were male (74.5%). The mean albumin level on admission was 2.9+/-1.8. Five hundred ninety-three (58%) patients were admitted with a serum albumin level of > or =2.6 as compared to 430 patients (42%) with an admission albumin level of <2.6. Patients with a lower serum albumin level were found to have a significantly greater ICU (17.1 vs 14.2 days) and hospital length of stay (17.3 vs 20.1 days, P'< 0.05), ventilator days (11.1 vs 13.5 days, P < 0.05), and mortality (P = 0.008) when matched for age and injury severity. The relative risk of infection and mortality increased greater than 2.5-fold in patients with increased age and low serum albumin when analyzed by multilinear regression analysis, P < 0.001. An admission serum albumin level of <2.6 g/dL is a significant independent predictor of morbidity and mortality in trauma patients. The combination of increased age and low albumin level was most predictive of infection and mortality. Early nutrition should be considered in these high-risk patients.

The clinical determinants of energy expenditure in critically injured adults require definition. Among adult blunt trauma victims who required mechanical ventilation, the resting energy expenditure was calculated with the Harris-Benedict equation (HBEE) and the early (< or = 5 days postinjury) energy expenditure was measured by indirect calorimetry (MEE) (n = 115). The MEE was 2052 +/- 531 kcal/day and MEE/HBEE ("stress factor") was 1.24 +/- 0.2. The MEE was correlated with HBEE, age, height, weight, sex, temperature, and paralytic agents (p < 0.01). However, MEE did not correlate with ISS, admission GCS score, admission base deficit, initial systolic blood pressure, or the number of units of packed red blood cells transfused in the first 24 hours after injury (p = NS). Temperature and paralysis correlated with MEE/HBEE (p < 0.01). A regression model of MEE was developed with the clinical variables HBEE, temperature, and the presence or absence of paralytic agents (r2 = 0.62; p < 0.001): MEE (kcal/d) = 1.4(HBEE) + 71.4(temperature) + 274(paralytics; + = 1, - = 2) - 3485. In mechanically ventilated trauma victims, both the early energy expenditure and the stress factor are determined by host factors but are independent of the severity of the anatomic and physiologic insult. The degree of hypermetabolism observed in this population was less than previously reported.

The objective of this study was to investigate the feasibility of using ultrasound (US) in place of portable chest x-ray (CXR) for the rapid detection of a traumatic pneumothorax (PTX) requiring urgent decompression in the trauma bay. All patients who presented as a trauma alert to a single institution from August 2011 to May 2012 underwent an extended focused assessment with sonography for trauma (FAST). The thoracic cavity was examined using four-view US imaging and were interpreted by a chief resident (Postgraduate Year 4) or attending staff. US results were compared with CXR and chest computed tomography (CT) scans, when obtained. The average age was 37.8 years and 68 per cent of the patients were male. Blunt injury occurred in 87 per cent and penetrating injury in 12 per cent of activations. US was able to predict the absence of PTX on CXR with a sensitivity of 93.8 per cent, specificity of 98 per cent, and a negative predictive value of 99.9 per cent compared with CXR. The only missed PTX seen on CXR was a small, low anterior, loculated PTX that was stable for transport to CT. The use of thoracic US during the FAST can rapidly and safely detect the absence of a clinically significant PTX. US can replace routine CXR obtained in the trauma bay and allow more rapid initiation of definitive imaging studies.

The objective of this study was to determine whether there are gender-specific associations between trauma exposure and alcohol or drug relapse in alcohol-dependent adults. Participants were 51 men (n = 24) and women (n = 27) with alcohol dependence, 22 (43.1%) of whom relapsed during study participation. Severity of childhood trauma; number of lifetime events evoking fear, helplessness, or horror; and current trauma symptoms all predicted relapse in women, but not in men. These findings highlight the importance of assessing trauma history and providing treatment of trauma-related symptoms for individuals with alcohol and drug dependence, and for women in particular.

We have previously reported that chronic intermittent hypoxia (CIH), a central feature of human sleep-disordered breathing, causes respiratory instability in sleeping rats (Edge D, Bradford A, O'halloran KD. Adv Exp Med Biol 758:359-363, 2012). Long term facilitation (LTF) of respiratory motor outputs following exposure to episodic, but not sustained, hypoxia has been described. We hypothesized that CIH would enhance ventilatory LTF during sleep. We examined the effects of 3 and 7 days of CIH exposure on the expression of ventilatory LTF in sleeping rats. Adult male Wistar rats were exposed to 20 cycles of normoxia and hypoxia (5 % O(2) at nadir; SaO(2) ~ 80 %) per hour, 8 h per day for 3 or 7 consecutive days (CIH, N = 7 per group). Corresponding sham groups (N = 7 per group) were subjected to alternating cycles of air under identical experimental conditions in parallel. Following gas exposures, breathing during sleep was assessed in unrestrained, unanaesthetized animals using the technique of whole-body plethysmography. Rats were exposed to room air (baseline) and then to an acute IH (AIH) protocol consisting of alternating periods of normoxia (7 min) and hypoxia (FiO(2) 0.1, 5 min) for 10 cycles. Breathing was monitored during the AIH exposure and for 1 h in normoxia following AIH exposure. Baseline ventilation was elevated after 3 but not 7 days of CIH exposure. The hypoxic ventilatory response was equivalent in sham and CIH animals after 3 days but ventilatory responses to repeated hypoxic challenges were significantly blunted following 7 days of CIH. Minute ventilation was significantly elevated following AIH exposure compared to baseline in sham but not in CIH exposed animals. LTF, determined as the % increase in minute ventilation from baseline following AIH exposure, was significantly blunted in CIH exposed rats. In summary, CIH leads to impaired ventilatory responsiveness to AIH. Moreover, CIH blunts ventilatory LTF. The physiological

Traumatic disease is a major public health concern. Monitoring the quality of services provided is essential for the maintenance and improvement thereof. Assessing and monitoring the quality of care in trauma patient through quality indicators would allow identifying opportunities for improvement whose implementation would improve outcomes in hospital mortality, functional outcomes and quality of life of survivors. Many quality indicators have been used in this condition, although very few ones have a solid level of scientific evidence to recommend their routine use. The information contained in the trauma registries, spread around the world in recent decades, is essential to know the current health care reality, identify opportunities for improvement and contribute to the clinical and epidemiological research.

Hypovolaemic shock that results through traumatically inflicted haemorrhage can have disastrous consequences for the victim. Initially the body can compensate for lost circulating volume, but as haemorrhage continues compensatory mechanisms fail and the patient's condition worsens significantly. Hypovolaemia results in the lethal triad, a combination of hypothermia, acidosis and coagulopathy, three factors that are interlinked and serve to worsen each other. The lethal triad is a form of vicious cycle, which unless broken will result in death. This report will focus on the role of hypothermia (a third of the lethal triad) in trauma, examining literature to assess how prehospital temperature control can impact on the trauma patient. Spontaneous hypothermia following trauma has severely deleterious consequences for the trauma victim; however, both active warming of patients and clinically induced hypothermia can produce particularly positive results and improve patient outcome. Possible coagulopathic side effects of clinically induced hypothermia may be corrected with topical haemostatic agents, with the benefits of an extended golden hour given by clinically induced hypothermia far outweighing these risks. Active warming of patients, to prevent spontaneous trauma induced hypothermia, is currently the only viable method currently available to improve patient outcome. This method is easy to implement requiring simple protocols and contributes significantly to interrupting the lethal triad. However, the future of trauma care appears to lie with clinically induced therapeutic hypothermia. This new treatment provides optimism that in the future the number of deaths resulting from catastrophic haemorrhaging may be significantly lessened.

Trauma patients are a diverse population with heterogeneous needs for ventilatory support. This requirement depends mainly on the severity of their ventilatory dysfunction, degree of deterioration in gaseous exchange, any associated injuries, and the individual feasibility of potentially using a noninvasive ventilation approach. Noninvasive ventilation may reduce the need to intubate patients with trauma-related hypoxemia. It is well-known that these patients are at increased risk to develop hypoxemic respiratory failure which may or may not be associated with hypercapnia. Hypoxemia in these patients is due to ventilation perfusion mismatching and right to left shunt because of lung contusion, atelectasis, an inability to clear secretions as well as pneumothorax and/or hemothorax, all of which are common in trauma patients. Noninvasive ventilation has been tried in these patients in order to avoid the complications related to endotracheal intubation, mainly ventilator-associated pneumonia. The potential usefulness of noninvasive ventilation in the ventilatory management of trauma patients, though reported in various studies, has not been sufficiently investigated on a large scale. According to the British Thoracic Society guidelines, the indications and efficacy of noninvasive ventilation treatment in respiratory distress induced by trauma have thus far been inconsistent and merely received a low grade recommendation. In this review paper, we analyse and compare the results of various studies in which noninvasive ventilation was applied and discuss the role and efficacy of this ventilator modality in trauma.

The objective of this study was to determine the incidence and interobserver agreement of individual CT findings as well as the bowel injury prediction score (BIPS) in surgically proven bowel injury after blunt abdominal trauma. This HIPAA-compliant retrospective study was IRB approved and consent was waived. All patients 14 years or older who sustained surgically proven bowel injury after blunt abdominal trauma between 1/1/2004 and 6/30/2015 were included. Admission trauma MDCT scans were independently interpreted by two abdominal fellowship-trained radiologists who recorded the following CT findings: intraperitoneal fluid, mesenteric hematoma/fat stranding, bowel wall thickening/hematoma, active intravenous contrast extravasation, free intraperitoneal air, bowel wall discontinuity, and focal bowel hypoenhancement. Subsequently, the electronic medical records of the included patients, admission abdominal physical exam results, admission white blood cell count, and findings at exploratory laparotomy of the included patients were recorded. Thirty-three patients met the inclusion criteria. The incidence and interobserver agreement of the CT findings were as follows: intraperitoneal fluid 93.9 %, kappa = 0.784 (good); mesenteric hematoma/fat stranding 84.8 %, kappa = 0.718 (good); bowel wall thickening/hematoma 42.4 %, kappa = 0.491 (moderate); active IV contrast extravasation 36.3 %, kappa = 1.00 (perfect); free intraperitoneal air 21.2 %, kappa = 0.904 (very good), bowel wall discontinuity 6.1 %, kappa = 1.00 (perfect); and focal bowel hypoenhancement 6.1 %, kappa = 0.468 (moderate). An absence of the specified CT findings was encountered in 9.1 % with surgically proven bowel injuries (kappa = 1.00, perfect). In our study, 9/16 patients or 56.3 % had a bowel injury prediction score (BIPS) of 2 or more as defined by McNutt et al. (J Trauma Acute Care Surg 78(1):105-111, 2014). The presence of intraperitoneal fluid and

The present obesity epidemic makes determining the normal heart weight in adults difficult. This study examines the heart weight at autopsy in 104 women aged 20 to 29 years who died in 1978 to 1980 before the overweight epidemic ensued. Of the 104 cases, the hearts weighed ≤300 g in 86 (83%) and >300 g in 18 (17%). Of the 67 cases dying from an unnatural cause (trauma or chemical intoxication), only 3 (4%) had hearts weighing >300 g; of the 37 patients dying from a variety of natural causes, 15 (41%) had hearts weighing >300 g (p <0.001). The body mass index (BMI) was ≤25 kg/m(2) in 82 cases (79%) and the hearts in them ranged from 120 to 400 g (mean 262 ± 51; median 257 g); of the 22 cases (21%) in whom the BMI was >25 kg/m(2), the hearts ranged from 230 to 850 g (mean 351 ± 142; median 300 g). In conclusion, the cases dying from an unnatural cause had smaller mean heart weights than those women dying from a natural cause and those with a normal BMI (≤25 kg/m(2)) had smaller mean heart weights than those with a BMI >25 kg/m(2). The normal heart weight in young women dying from an unnatural cause with few exceptions is <300 g.
As a momentous disaster, earthquake would bring severe psychological trauma to children, with an adverse effect not only on the physiological functions, but also on their behaviors, emotions, and cognition, and the short-term and long-term consequences are much greater in children than in adults. The children of different ages have different psychological reactions, so psychological intervention varies with children's age. Psychological intervention is still important long afterwards to prevent permanent psychological trauma in children.

Study Design Retrospective comparative study. Objective To compare strict Biffl criteria to more-liberal criteria for computed tomography angiography (CTA) when screening for blunt cerebrovascular injury (BCVI). Methods All CTAs performed for blunt injury between 2009 and 2011 at our institution were reviewed. All patients with cervical spine fractures who were evaluated with CTA were included; patients with penetrating trauma and atraumatic reasons for imaging were excluded. We then categorized the patients' fractures based on the indications for CTA as either within or outside Biffl criteria. For included subjects, the percentage of studies ordered for loose versus strict Biffl criteria and the resulting incidences of BCVI were determined. Results During our study period, 1,000 CTAs were performed, of which 251 met inclusion criteria. Of the injuries, 192 met Biffl criteria (76%). Forty-nine were found to have BCVIs (19.5%). Forty-one injuries were related to fractures meeting Biffl criteria (21.4%), and 8 were related to fractures not meeting those criteria (13.6%). The relative risk of a patient with a Biffl criteria cervical spine injury having a vascular injury compared with those imaged outside of Biffl criteria was 1.57 (p = 0.19). Conclusions Our data demonstrates that although cervical spine injuries identified by the Biffl criteria trend toward a higher likelihood of concomitant BCVI (21.4%), a significant incidence of 13.6% also exists within the non-Biffl fracture cohort. As a result, a more-liberal screening than proposed by Biffl may be warranted. PMID:27781188

Light body armor development for the warfighter is based on trial-and-error testing of prototype designs against ballistic projectiles. Torso armor testing against blast is nonexistent but necessary to protect the heart and lungs. In tests against ballistic projectiles, protective apparel is placed over ballistic clay and the projectiles are fired into the armor/clay target. The clay represents the human torso and its behind-armor, permanent deflection is the principal metric used to assess armor protection. Although this approach provides relative merit assessment of protection, it does not examine the behind-armor blunt trauma to crucial torso organs. We propose a modeling and simulation (M&S) capability for wound injury scenarios to the head, neck, and torso of the warfighter. We will use this toolset to investigate the consequences of, and mitigation against, blast exposure, blunt force impact, and ballistic projectile penetration leading to damage of critical organs comprising the central nervous, cardiovascular, and respiratory systems. We will leverage Sandia codes and our M&S expertise on traumatic brain injury to develop virtual anatomical models of the head, neck, and torso and the simulation methodology to capture the physics of wound mechanics. Specifically, we will investigate virtual wound injuries to the head, neck, and torso without and with protective armor to demonstrate the advantages of performing injury simulations for the development of body armor. The proposed toolset constitutes a significant advance over current methods by providing a virtual simulation capability to investigate wound injury and optimize armor design without the need for extensive field testing.

Traumatic injuries to already abnormal kidneys are difficult to assess by excretory urography and clinical evaluation. Bleeding and urinary extravasation may accompany minor trauma; conversely, underlying tumors, perirenal hemorrhage, and extravasation may be missed on urography. Computed tomography (CT) was performed in eight cases including three neoplasms, one adult polycystic disease, one simple renal cyst, two hydronephrotic kidneys, and one horseshoe kidney. CT provided specific and clinically useful information in each case that was not apparent on excretory urography.

Numerous techniques and treatments have been described for scar revision, with most studies focusing on the adult population. A comprehensive review of the literature reveals a paucity of references related specifically to scar revision in children. This review describes the available modalities in pediatric facial scar revision. The authors have integrated current practices in soft tissue trauma and scar revision, including closure techniques and materials, topical therapy, steroid injection, cutaneous laser therapy, and tissue expanders.

The timely administration of analgesics is crucial to the comprehensive management of trauma patients. When an emergency department (ED) pharmacist participates in trauma resuscitation, the pharmacist acts as a medication resource for trauma team members and facilitates the timely administration of analgesics. This study measured the impact of a pharmacist on time to first analgesic dose administered during trauma resuscitation. All adult (>18 years) patients who presented to this level II trauma center via activation of the trauma response system between January 1, 2009, and May 31, 2013, were screened for eligibility. For inclusion, patients must have received intravenous fentanyl, morphine, or hydromorphone in the trauma bay. The time to medication administration was defined as the elapsed time from ED arrival to administration of first analgesic. There were 1328 trauma response system activations during the study period; of which 340 patients were included. The most common analgesic administered was fentanyl (62% in both groups). When a pharmacist was participating, the mean time to first analgesic administered was decreased (17 vs 21 minutes; P = .03). Among the 78% of patients with documented pain scores, the overall mean reduction in pain scores from ED arrival to ED discharge was similar between the 2 groups. There was a 2.4 point reduction with a pharmacist versus 2.7 without a pharmacist, using a 0 to 10 numeric pain rating scale. The participation of a clinical pharmacist during trauma resuscitation significantly decreased the time to first analgesic administration in trauma patients. The results of this study supplement the literature supporting the integration of clinical ED pharmacists on trauma teams.

The focused assessment with sonography for trauma examination has assumed the role of initial screening examination for the presence or absence of hemoperitoneum in the patient with blunt abdominal trauma. Sonographic pitfalls associated with the examination have primarily been related to mistaking contained fluid collections with hemoperitoneum. We present a case in which an elongated left lobe of the liver was misdiagnosed as a splenic subcapsular hematoma. It is imperative that emergency physicians and trauma surgeons be familiar with this normal variant of the liver and its associated sonographic appearance on the perisplenic window in order to prevent nontherapeutic laparotomies or embolizations.

The incompressible subsonic aerodynamics of four entry-vehicle shapes with variable c.g. locations are examined in the Langley 20-Foot Vertical Spin Tunnel. The shapes examined are spherically-blunted cones with half-cone angles of 30, 45, and 60 deg. The nose bluntness varies between 0.25 and 0.5 times the base diameter. The Reynolds number based on model diameter for these tests is near 500,000. Quantitative data on attitude and location are collected using a video-based data acquisition system and reduced with a six deg-of-freedom inverse method. All of the shapes examined suffered from strong dynamic instabilities which could produced limit cycles with sufficient amplitudes to overcome static stability of the configuration. Increasing cone half-angle or nose bluntness increases drag but decreases static and dynamic stability.

Background Although used primarily in the pediatric population for decades, the use of intraosseous (IO) devices in the resuscitation of severely injured adult trauma patients has recently become more commonplace. The objective of this study was to determine the experience level, beliefs and attitudes of trauma practitioners in Canada, Australia and New Zealand regarding the use of IO devices in adult trauma patients. Methods We administered a web-based survey to all members of 4 national trauma and emergency medicine organizations in Canada, Australia and New Zealand. Survey responses were analyzed using descriptive statistics, univariate comparisons and a proportional odds model. Results Overall, 425 of 1771 members completed the survey, with 375 being trauma practitioners. IO devices were available to 97% (353 of 363), with EZ-IO being the most common. Nearly all physicians (98%, 357 of 366) had previous training with IO devices, and 85% (223 of 261) had previously used an IO device in adult trauma patients. Most respondents (79%, 285 of 361) were very comfortable placing an IO catheter in the proximal tibia. Most physicians would always or often use an IO catheter in a patient without intravenous access undergoing CPR for traumatic cardiac arrest (84%, 274 of 326) or in a hypotensive patient (without peripheral intravenous access) after 2 attempts or 90 s of trying to establish vascular access (81%, 264 of 326). Conclusion Intraosseous devices are readily available to trauma practitioners in Canada, Australia and New Zealand, and most physicians are trained in device placement. Most physicians surveyed felt comfortable using an IO device in resuscitation of adult trauma patients and would do so for indications broader than current guidelines. PMID:27669404

Objectives—To determine the prevalence and patterns of alcohol and drug use in patients with major trauma. Methods—Consecutive trauma patient enrolment, 24 hours a day, was envisaged with anonymised patient data on gender, age band, and mechanism of injury collected. The study group had surplus plasma quantitatively analysed for ethanol concentration, and urine samples were initially screened, via immunoassay, for opiates, cannabinoids, amphetamines, benzodiazepines, cocaine, and methadone. Confirmation and specification of individual positive results was then performed using thin layer or gas-liquid chromatography. Drugs of treatment given in the resuscitation room, if subsequently detected in the urine samples, were excluded from the final results. Results—There were 116 eligible trauma patients assessed and treated in the resuscitation room over a six month period, of which 93 (80%) were enrolled. Altogether 27% of this trauma population had plasma ethanol concentrations greater than 80 mg/dl. There was a significantly higher prevalence of alcohol intoxication in the group not involved in a road traffic accident (RTA) compared with the group who were involved in a RTA. Initial screening of urine for drugs revealed a prevalence of 51%. After 12 exclusions due to iatrogenic administration of opiates, the final confirmed prevalence was 35% in this trauma population. The individual drug prevalence was 13% for cannabinoids, 11% for codeine, 8% for morphine, 6% for amphetamine, 6% for benzodiazepines, 3% for cocaine, 1% for dihydrocodeine, and 1% for methadone. Conclusions—There is a notable prevalence of drug and alcohol use in this British accident and emergency trauma population. A significantly higher prevalence for alcohol intoxication was found in the non-RTA group compared with the RTA group. The patterns of drug usage detected reflect local influences and less cocaine use is seen compared with American studies. The association between alcohol, drugs

The aim of this study was to assess the role of thoracoscopy in the evaluation of the cause of persistent intrathoracic bleeding, air leak, or nuclear basal opacification after blunt thoracic trauma. As a result, a decision to proceed to early thoracotomy could be made, or an attempt of thoracoscopic haemostasis, haematoma evacuation, or fistula closure was possible. Twelve patients (9 male, 3 female, mean age 33,7 years) with blunt thoracic trauma underwent video-assisted thoracoscopy under general anaesthesia with double-lumen endotracheal intubation and one-lung ventilation. The indication for operation was made after assessment of chest X-ray and CT findings, pleural ultrasound, and the volume and quality of pleural drainage. Persistent pneumothorax was shown to be due to traumatic rupture of a bulla in two cases and to parenchymal air-leak from a small lung laceration in two cases, all of which were treated endoscopically. In two cases a diaphragmatic rupture was confirmed as the cause of basal shadowing and in one case a major lower lobe laceration was identified as the cause of a persistent haemopneumothorax. In three cases, a fluid collection which could not be evacuated through a pleural drain was shown to be an organised haematoma and was removed endoscopically. Video-assisted thoracoscopy is helpful in the diagnosis and treatment of thoracic trauma, allowing early recognition of injuries that require thoracotomy. It is indicated for persistent (but not life-threatening) intrathoracic bleeding, unresolving pneumothorax, and unclear basal opacification. Therapeutic parenchymal tissue glue application and suturing as well as local resection and haematoma evacuation can be performed with this technique.

The aim of this study was to examine the contributory role of childhood and adulthood trauma events and the appraisal of self-discrepancy (the magnitude and distress) in overgeneral memory retrieval (OGM) using a non-clinical sample. Participants with a history of childhood trauma (n=29); adulthood trauma only (n=17) or no-trauma (n=26) participated in this study.
