[Application of statistical models for prognostication of outcomes in injured persons with severe trauma]

Basing on data, concerning the injured persons state, the investigations results for elaboration and application of statistic models, prognosticating the trauma outcome, were analyzed. Selected information about 373 injured persons, who were treated in Traumatic Shock Department, is presented. There was established, that the statistical models elaborated is expedient to use together with other qualitative and quantitative methods of prognostic determination of outcome in severely injured persons.

The ins and outs of terrorist bus explosions: injury profiles of on-board explosions versus explosions occurring adjacent to a bus

BACKGROUND

Terrorist explosions occurring in varying settings have been shown to lead to significantly different injury patterns among the victims, with more severe injuries generally arising in confined space attacks. Increasing numbers of terrorist attacks have been targeted at civilian buses, yet most studies focus on events in which the bomb was detonated within the bus. This study focuses on the injury patterns and hospital utilisation among casualties from explosive terrorist bus attacks with the bomb detonated either within a bus or adjacent to a bus.

METHODS

All patients hospitalised at six level I trauma centres and four large regional trauma centres following terrorist explosions that occurred in and adjacent to buses in Israel between November 2000 and August 2004 were reviewed. Injury severity scores (ISS) were used to assess severity. Hospital utilisation data included length of hospital stay, surgical procedures performed, and intensive care unit (ICU) admission.

RESULTS

The study included 262 victims of 22 terrorist attacks targeted at civilian bus passengers and drivers; 171 victims were injured by an explosion within a bus (IB), and 91 were injured by an explosion adjacent to a bus (AB). Significant differences were noted between the groups, with the IB population having higher ISS scores, more primary blast injury, more urgent surgical procedures performed, and greater ICU utilisation. Both groups had percentages of nearly 20% for burn injury, had high percentages of injuries to the head/neck, and high percentages of surgical wound and burn care.

CONCLUSIONS

Explosive terrorist attacks detonated within a bus generate more severe injuries among the casualties and require more urgent surgical and intensive level care than attacks occurring adjacent to a bus. The comparison and description of the outcomes to these terrorist attacks should aid in the preparation and response to such devastating events.

Blunt assault: 'million dollar baby'

Contrasting reports exist in the literature regarding the management of patients with blunt assault to the head, neck, and face and more importantly for clearing the cervical spine. The purpose of our study was to determine the risk of cervical spine injuries after blunt assault to the head, neck, and face and its association with other injuries. We performed a retrospective case review of all blunt assault trauma admissions to the head, neck, and face at our Level I trauma center. We identified all patients who were assaulted with hands and feet and blunt instruments. A total of 3286 patients with blunt assault to the head, neck, and face were identified of whom 11 (0.003%) were found to have a cervical spine fracture or cervical spine subluxation. None of the patients had a cervical spinal cord injury. The 11 patients composed our study population with a mean age of 39 ± 7.8 years, 100 per cent were male, and the mean Injury Severity Score was 12 ± 7.9. Five (45%) patients required surgery for stabilization of the cervical spine. Mortality was reported in only one patient who had a C7 transverse process fracture. Cervical spine injury after blunt assault is rare but does occur and encompasses significant injuries requiring surgical intervention. However, these injuries are the result of direct blows to the cervical spine and we suggest that assaulted patients with no direct trauma to the neck do not require an exhaustive evaluation of the cervical spine.

Emergency management of blunt chest trauma in children: an evidence-based approach

Pediatric trauma is commonly encountered in the emergency department, and trauma to the head, chest, and abdomen may be a source of significant morbidity and mortality. As children have unique thoracic anatomical and physiological properties, they may present with diagnostic challenges that the emergency clinician must be aware of. This review examines the effects of blunt trauma to the pediatric chest, as well as its relevant etiologies and associated mortality. Diagnostic and treatment options for commonly encountered injuries such as pulmonary contusions, rib fractures, and pneumothoraces are examined. Additionally, this review discusses rarely encountered--yet highly lethal--chest wall injuries such as blunt cardiac injuries, commotio cordis, nonaccidental trauma, and aortic injuries.

Aortic arch blunt injury in front-seat passenger

Aortic arch blunt injury has highly lethal nature. Because the physical examination findings are subtle, immediate medical evaluation is very important. The case was a 72-year-old woman. Massive haemorrhage in the left haemotorax, contusion area in the left lung and a traumatic transection of the distal aortic arch was observed during autopsy. We described intersting autopsy case of aortic arch blunt injury.

Seatbelt sign as an indication for four-vessel computed tomography angiogram of the neck to diagnose blunt carotid artery and other cervical vascular injuries

Computed tomography angiography (CTA) of the neck has become the most common modality for diagnosing blunt carotid artery injury (BCAI). The protocol at our institution includes CTA on trauma patients with a seatbelt sign. The purpose of this study is to evaluate whether a solitary seatbelt sign is an indication for CTA of the neck to diagnose BCAI. We conducted a retrospective review of patients from 2000 to 2010 who received CTAs as a result of a seatbelt sign performed at our Level I trauma center. Four hundred eighteen patients received CTAs based on the presence of a seatbelt sign. Two hundred twenty-six had skeletal injuries, obvious soft tissue injuries, and/or positive findings on imaging, including 11 positive vascular findings with two BCAIs found. Patients with noncarotid vascular injuries on CTA had a higher Injury Severity Score than patients with solitary seatbelt signs (11.4 ± 7.6 vs 3.4 ± 4.2, P < 0.01). The correlation between seatbelt sign and positive finding on CTA was weak (r = 0.007). Patients with vascular findings on CTA also had obvious hard/soft tissue injuries and/or positive findings on standard trauma imaging. This suggests that a protocol for CTA of the neck for patients with a seatbelt sign can be reserved for those with associated injuries on physical examination and/or findings on standard trauma imaging.

Traumatic wound dehiscence after deep anterior lamellar keratoplasty

PURPOSE

To analyze the outcomes of traumatic wound dehiscence after deep anterior lamellar keratoplasty (DALK).

DESIGN

Retrospective and interventional case series.

METHODS

SETTING

Single hospital.

PATIENTS

A total of 338 consecutive cases were reviewed. Eleven eyes that had wound dehiscence related to ocular trauma were included.

MAIN OUTCOME MEASURES

Incidence and causes, best-corrected visual acuity (BCVA), and endothelial cell density were evaluated. Complications and secondary surgeries were recorded.

RESULTS

Seven patients were male (63.6%) and 4 patients were female (36.4%), with a mean age of 30.6 years (range, 24-40 years). The incidence of wound dehiscence was 3.2% (11/338). The mean interval between the initial DALK procedure and wound dehiscence was 9.45 months (range, 2-16 months). The mean follow-up time was 6 years. The most common trauma was a fist blow injury (36.3%). Descemet membrane perforation was observed in 8 eyes (72.7%); lens damage and vitreous prolapse occurred in 2 eyes (18.1%). The final BCVA was 0.51 and was maintained in 4 eyes (36.3%). At the final visit, 10 grafts (90.9%) were clear. The mean endothelial cell loss was 55.8% between before DALK and last visit.

CONCLUSION

Although the intact Descemet membrane protects against dehiscing traumas after DALK, a relative weakness at the graft-host junction tends to persist and a severe deforming force may result in graft dehiscence. This case series indicates that despite the fact that the visual results following the repair are acceptable, corneal endothelium seems to be subjected to severe damage, which puts graft survival chances at risk in the long term.

Ear trauma

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.

Traumatic colon injuries -- factors that influence surgical management

BACKGROUND

This study sought to evaluate current trends in surgical management of colon injuries in a level I urban trauma centre, in the light of our increasing confidence in primary repair.

METHODS

Our retrospective study evaluates the results of 116 patients with colon injuries operated at Bucharest Clinical Emergency Hospital, in the light of some of the most commonly cited factors which could influence the surgeon decision-making process towards primary repair or colostomy.

RESULTS

Blunt injuries were more common than penetrating injuries (65% vs. 31%). Significant other injuries occurred in 85 (73%) patients. Primary repair was performed in 95 patients (82%). Fecal diversion was used in 21 patients(18%). Multiple factors influence the decision-making process: shock, fecal contamination, associated injuries and higher scores on the Abdominal Trauma Index (ATI) and Colon Injury Scale (CIS). Colon related intra-abdominal complications occurred in 7% of patients in whom the colon injury was closed primarily and in 14% of patients in whom a stoma was created, ATI having a predictive role in their occurrence. The overall mortality rate was 19%.

CONCLUSIONS

Primary repair of colon injuries, either by primary suture or resection and anastomosis, is a safe method in the management of the majority of colonic injuries. Colostomy is preferred for patients with ATI ≥ 30 and CIS ≥ 4. Surgical judgment remains the final arbiter in decision making.

Management of blunt renal trauma in Srinagarind Hospital: 10-year experience

BACKGROUND

Renal trauma is the most common injury in the urogenital system. In the last decade the management has beer shifted f rom a mandatory exploration to conservative treatment. So, the present study was conducted to evaluate the result f, renal trauma patients.

MATERIAL AND METHOD

The data of renal trauma patients treated at Srinagarind Hospital since 1 January 1998 to 31 December 2007 was collected. Clinical data and trauma score were obtained via medical record review.

RESULTS

Sixty-nine patients were included; 59 were male (82%). Mean age was 29.8 years (1-68 years). Forty-nine patiens: (80%) were injured by traffic accident. Eighteen percents of patients also had splenic injury. Fifty-five patients (80%) of blunt renal injury patients were treated by Non-Operative Management (NOM). In this group, most patients had grade I injury (39%). Mean injury severity score (ISS), revised trauma score (RTS), trauma and injury severity score (TRISS) were 20, 7.3 and 0.93, respectively. Successful rate of non-operative management was 87.2%. Mean hospital stay was 11.8 days and urinary tract infection was the most frequent complication (10%). Fourteen patients (20%) underwent surgery. Mean ISS, RTS, TRISS were 20.8, 5.5, and 0.72, respectively. In the operative group, 71% were grade 5 injury and almost all were treated by nephrectomy. Mean hospital stay was 9 days.

CONCLUSION

Blunt injury is the major cause of renal trauma and the main mechanism is traffic accident. The success rate of Non-Operative Management in Srinagarind Hospital was high. However operative management is still the standard treatment in unstable patients.

[On the method of forensic medical examination of the injuries inflicted and traces left by the objects having the rubber surface]

A method of forensic medical examination of the injuries inflicted and traces left by the objects having the rubber surface is proposed. The method permits to reveal the facts of contact of injurious rubber things with biological and non-biological objects. Its application extends the possibilities for determining the direction of movement and the weight of a vehicle running over the body of the victim.

Camel-related pancreatico-duodenal injuries: a report of three cases and review of literature

BACKGROUND

Human pancreatico-duodenal injuries caused by camels are extremely rare.

OBJECTIVE

We report three patients who sustained camel-related pancreatico-duodenal injuries and review the literature on this topic.

RESULTS

A 32-year camel caregiver was kicked by a camel which then stepped on his abdomen trying to kill him. The patient's abdomen was soft and lax. CT scan of the abdomen showed free retroperitoneal air. Laparotomy revealed a complete tear of the anterior wall of the second part of duodenum which was primarily repaired. A 40-year camel caregiver was directly kicked into his abdomen by a camel. He developed traumatic pancreatitis which was treated conservatively. A 31-year-old male fell down on his abdomen while riding a camel. Abdominal examination revealed tenderness and guarding. Abdominal CT Scan showed complete transection of the neck of the pancreas which was confirmed by laparotomy. The patient had distal pancreatectomy with preservation of the spleen. All patients were discharged home in good condition.

CONCLUSION

These cases demonstrate the misleading presentation of the camel-related pancreatico-duodenal injuries and their unique mechanism of injury.

Successful repair of bilateral common carotid artery dissections from hanging

The management of blunt carotid artery dissections caused by hanging remains controversial, especially with regard to diagnostic work-up and treatment options. We present 2 men, 49 and 41 years of age, who were treated for bilateral common carotid artery dissection caused by strangulation. In the first patient, additional cricotracheal separation and blunt thyroid gland trauma was observed. Bilateral saphenous vein graft interposition was accomplished in both patients. In the first patient, tracheal repair and suture of the thyroid gland completed the procedure. At 1 year of follow-up, both patients were capable of managing their lives independently. A systematic review of the literature on managing near-hanging and nonfatal strangulation victims is included in this report to allow this case series to be put into perspective.

A case of hemothorax following seat-belt injury with a bulla in the apex of the lung: a subtype of spontaneous hemopneumothorax

We experienced a case of a subtype of spontaneous hemopneumothorax caused by external forces associated with a seat-belt injury. A female aged 39 years sustained a minor collision with an oncoming car while she was driving. Although pneumothorax was not detected, hemothorax and bleeding from the area surrounding the subclavian artery were observed on contrast-enhanced chest computed tomography (CT). After confirming continuous bleeding into the thoracic cavity after superselective arterial embolization, we performed emergency open surgery. We found a bulla in the apex of the lung, and the thoracic stump of the bulla was considered the source of bleeding. In this case, the direct cause of hemothorax was considered to be the external force associated with the seat-belt injury. When a bulla in the apex of the lung and continuous bleeding are both observed on CT, spontaneous hemopneumothorax should be suspected, necessitating open chest surgery in cases where pneumothorax is not observed.

Blunt aortic injury secondary to fragmented tenth thoracic vertebral body

We present a case of blunt traumatic aortic laceration following a motor vehicle crash. The aortic laceration was 4.5 cm above the coeliac axis and occurred because of an unstable tenth thoracic vertebral body. Open surgery was considered high risk, whereas an endovascular approach with an endoprosthesis placed at the exact anatomic location of the laceration was advocated.

Watercraft and watersport injuries in children: trauma mechanisms and proposed prevention strategies

PURPOSE

Watercraft-associated trauma (WAT) in children has received little attention so far, despite the potentially severe and debilitating resulting injuries. The aim of this study was to evaluate all cases of major watercraft-associated trauma admitted to the Children's of Alabama during the past 10 years, identify patterns in mechanism and injury, and propose future prevention strategies.

METHODS

We reviewed our (prospective) database for children admitted through our trauma center after major WAT. Charts were abstracted for mechanism, epidemiologic data, injury type and injury severity scale (ISS), as well as outcome.

RESULTS

We identified 15 children (6 males, 9 females, age range 7 to 15, mean 12 ± 2 years), involved in 14 accidents. Sharp trauma was inflicted by a propeller (n=4) or a rope (n=1). Towed tubing (riding an inflatable tube while being pulled by a boat) was the most prevalent mechanism (n=6). There was a trend towards higher ISS after towed tubing (24.8 ± 12.4) compared to all other mechanisms (15.1±7.7). Mean length of stay was longer after towed tubing accidents (14.2 ± 7.2 versus 4.9 ± 3.4 days). All patients survived and eventually were discharged home. In one of the incidences, involving 2 victims of this series, the driver of the boat was intoxicated with alcohol.

CONCLUSIONS

Pediatric watercraft-related accidents are infrequent, but often result in major injuries. More awareness for safety measures to prevent these injuries is warranted. Alcohol is not a major factor in pediatric watercraft-associated trauma. Tubes towed by a boat seem to be particularly dangerous, perhaps because of the rider's limited maneuverability and the fact that centrifugal force lets the tube travel well outside the wake in curves. Limiting boat speed and the use of protective gear on towed tubes when children are involved may decrease the incidence and severity of pediatric WAT.

Main bronchial stenosis--sequel of delayed diagnosis after posttraumatic bronchial injury

Bronchial ruptures due to blunt chest traumas are rarely encountered injuries and frequently late diagnosed. Once the diagnostic is established by bronchoscopy surgical treatment is mandatory and usually, the results are very good. In order to conserve as much as possible lung parenchyma minimal possible resection is required. We present four cases managed in our department by means of main bronchial sleeve resection--two on the right side and two on the left side--with good outcome. We were able to save the entire lung in all four cases despite long-term atelectasis.

Abdominal aortic rupture from an impaling osteophyte following blunt trauma

Blunt injury of the abdominal aorta is highly fatal. We present an unusual case of an osteophyte impaling the abdominal aorta treated by endovascular repair. A 77-year-old man sustained a thoracolumbar fracture-dislocation with posterior aortic rupture between his celiac and superior mesenteric artery origins. His aortic injury was treated with a stent graft, excluding the celiac origin. He was dismissed on postoperative day 6. At 6 months, he had returned to most preinjury activities, and at 2-year follow-up, he continues to have good functional outcome. Endovascular repair may be successfully employed in select aortic injuries in hemodynamically stable patients.

Epidemiological features and management of complex neck trauma from an ENT surgeon's perspective

OBJECTIVES

The aim of this study is to present a clear picture of the epidemiological aspects pertaining to the cases of neck trauma addressing to the ENT Emergency Room, as well as to display the complexity of the diagnostic and therapeutic management employed in two important Romanian ENTDepartments - „Sfantul Spiridon” Hospital Iasi and SfantaMaria Hospital Bucharest

MATERIAL AND METHODS

We conducted a retrospective study on 538 patients with neck trauma that were referred to the abovementioned ENT Departments between March 2009 – March 2011, selecting 27 cases with forensic implications.

RESULTS

In terms of aetiological mechanism, the most frequentneck injuries in our study were penetrating neck injuries due to assault or self-mutilation with white weapons (knives, razor blades, forks, glass) - 56%, followed by blunt trauma cases due to car accident, strangulation or accidental fall – 44%. The most important clinical findings recorded at admission were polytraumas (24.14%), hematomas, fractures, subcutaneous emphysema or skin perforation with visceral damages(representing each 13.8%) and tissue rip (10.34%), important bleedings (6.89%), as well as perforation of neck organs(3.45%). The most frequent postoperative complications were postoperative pharyngo-cutaneous fistula (7.4%) and laryngotrachealstenosis (7.4%). There were also 3 other patients with long-term complications, such as acute mediastinitis (3.4%)recurrential paralysis with Gerhardt's syndrome (3.4%) and dysphagia (3.4%).

Pancreatic trauma

INTRODUCTION

Pancreatic trauma occurs in approximately 4% of all patients sustaining abdominal injuries. The pancreas has an intimate relationship with the major upper abdominal vessels, and there is significant morbidity and mortality associated with severe pancreatic injury. Immediate resuscitation and investigations are essential to delineate the nature of the injury, and to plan further management. If main pancreatic duct injuries are identified, specialised input from a tertiary hepatopancreaticobiliary (HPB) team is advised.

METHODS

A comprehensive online literature search was performed using PubMed. Relevant articles from international journals were selected. The search terms used were: 'pancreatic trauma', 'pancreatic duct injury', 'radiology AND pancreas injury', 'diagnosis of pancreatic trauma', and 'management AND surgery'. Articles that were not published in English were excluded. All articles used were selected on relevance to this review and read by both authors.

RESULTS

Pancreatic trauma is rare and associated with injury to other upper abdominal viscera. Patients present with non-specific abdominal findings and serum amylase is of little use in diagnosis. Computed tomography is effective in diagnosing pancreatic injury but not duct disruption, which is most easily seen on endoscopic retrograde cholangiopancreaticography or operative pancreatography. If pancreatic injury is suspected, inspection of the entire pancreas and duodenum is required to ensure full evaluation at laparotomy. The operative management of pancreatic injury depends on the grade of injury found at laparotomy. The most important prognostic factor is main duct disruption and, if found, reconstructive options should be determined by an experienced HPB surgeon.

CONCLUSIONS

The diagnosis of pancreatic trauma requires a high index of suspicion and detailed imaging studies. Grading pancreatic injury is important to guide operative management. The most important prognostic factor is pancreatic duct disruption and in these cases, experienced HPB surgeons should be involved. Complications following pancreatic trauma are common and the majority can be managed without further surgery.

Delayed presentation of blunt duodenal injuries in children. Case report and review of literature

BACKGROUND

Duodenal injuries are rare in children and classically present following a fall over the handle bar. Retroperitoneal location of the duodenum may lead to delay in diagnosis, and missed injuries are associated with increased morbidity and mortality.

CASE REPORT

A 5-year-old child was admitted to the National Trauma Center, in Tirana (Albania), 28 hours after a Motor Vehicle Crash (MVC), complaining of mild abdominal pain. He was febrile (39°C) and had a white blood cells count of 18,000 mm³. On physical exam he had mild tenderness. Plain abdominal X-rays and Focused Abdominal Sonography for Trauma (FAST) were negative for free air or free fluid. The CT scan of the abdomen demonstrated free air and fluid in the retroperitoneal space. At laparatomy, a perforation of the second portion of the duodenum was found. A single layer suture repair of the duodenum with wide drainage was performed. The patient was discharged from the hospital tolerating oral feeding 8 days later.

CONCLUSION

Duodenal injuries in children are rare. Most duodenal hematomas are managed non-operatively. This is a case of MCV with delayed presentation that was treated surgically for perforation successfully.
