We performed a trauma database analysis to identify the effect of concomitant cranial injuries on outcome in patients with fractures of the axis. We identified patients with axis fractures over a 14-year period. A binary outcome measure was used. Univariate and multiple logistic regression analysis were performed. There were 259 cases with axis fractures. Closed head injury was noted in 57% and skull base trauma in 14%. Death occurred in 17 cases (6%). Seventy-two percent had good outcome. Presence of abnormal computed tomography head findings, skull base fractures, and visceral injury was significantly associated with poor outcome. Skull base injury in association with fractures of the axis is a significant independent predictor of worse outcomes, irrespective of the severity of the head injury. We propose that presence of concomitant cranial and upper vertebral injuries require careful evaluation in view of the associated poor prognosis. PMID:22470268

The recurrent Heubner's artery is the distal part of the medial striate artery. Occlusion of the recurrent artery of Heubner, classically contralateral hemiparesis with fasciobrachiocrural predominance, is attributed to the occlusion of the recurrent artery of Heubner and is widely known as a stroke syndrome in adults. However, isolated occlusion of the deep perforating arteries following mild head trauma also occurs extremely rarely in childhood. Here we report the case of an 11-year-old boy with pure motor stroke. The brain MRI showed an acute ischemia in the recurrent artery of Heubner supply area following mild head trauma. His fasciobrachial hemiparesis and dysarthria were thought to be secondary to the stretching of deep perforating arteries leading to occlusion of the recurrent artery of Heubner. Post-traumatic pure motor ischemic stroke can be secondary to stretching of the deep perforating arteries especially in childhood.

To determine the prevalence of seizures in cats after head trauma. Retrospective cross-sectional study. 52 cats with head trauma. Information was obtained from medical records of cats with head trauma and via telephone interviews of owners at least 2 years after cats had head trauma. Severity of head trauma in cats was classified with the modified Glasgow coma scale (mGCS), and the association between scores and development of seizures was determined. 9 cats had moderate head trauma (mGCS score, 9 to 14), and 43 cats had mild head trauma (mGCS score, 15 to 18). None of the cats developed seizures during the follow-up period (≥ 2 years after head injury). The calculated 95% confidence interval for prevalence of seizures in cats after head injury was 0% to 5.6%. There was no significant relationship between severity of head trauma and the risk of seizures in cats. Results indicated the probability that cats with mild to moderate head trauma would develop posttraumatic seizures was low. However, clinicians should monitor cats with a history of head trauma for development of secondary epilepsy.

Integration of Osteopathic Manual Treatments in Management of Cervical Dystonia with Tremor: A Case Series

Halimi, Miriam; Leder, Adena; Mancini, Jayme D.

2017-01-01

Background Cervical dystonia, also known as spasmodic torticollis, is a chronic disorder in which patients exhibit involuntary repetitive contractions of neck muscles resulting in abnormal postures or movements. Occasionally, there is also a dystonic head tremor. The underlying mechanisms for cervical dystonia and dystonic tremor are not clear, and treatments are limited. Case Report In the present cases, two females with head tremor starting in adolescence developed worsening symptoms of cervical dystonia with dystonic tremor in their 60s. On osteopathic physical examination, both had a vertical type strain to the sphenobasilar synchondrosis. Discussion Vertical strains are more frequently found in patients after head trauma, congenital or later in life, than in healthy patients, and head trauma may have been a precipitating factor in these patients. There were improvements in cervical dystonia symptoms, including tremor, in both patients after osteopathic manual treatment. PMID:28119789

Asymptomatic Chiari Type I malformation: should patients be advised against participation in contact sports?

PubMed

Spencer, Robert; Leach, Paul

2017-08-01

Chiari type I malformation (CM-I) is characterised by caudal displacement of the cerebellar tonsils through the foramen magnum, crowding the craniocervical junction. It is being increasingly diagnosed in asymptomatic patients due to the widespread availability of MRI, and there are case reports of these patients suffering sudden death or neurological injury following head or neck trauma, raising the issue of whether they should be prohibited from contact sport participation, given the likelihood of frequent trauma. General neurosurgical opinion is that patients who are symptomatic and those with an associated spinal cord syrinx should be offered foramen magnum decompression, however asymptomatic patients without syringomyelia are not offered this in the majority of cases. The authors performed a full review of the published literature, including all case reports, case series, studies and literature reviews regarding CM-I and either contact sports or trauma, excluding patients that had undergone surgical intervention and those becoming symptomatic in circumstances other than head or neck trauma. 21 case reports of CM-I patients deteriorating following trauma were identified, including four cases of sudden death following head or neck injury. However, studies of large samples of CM-I patients are yet to capture an incident of sudden death or acute neurological deterioration, suggesting that the risk is very low. CM-I patients may have an increased risk of concussion and post-concussion syndrome compared to the background population however. Overall, the authors feel that there should be no restriction of sports participation for CM-I patients, but a discussion to make them and their families aware of the possible increased risks is important.

Background Investigation of unjustified computed tomography (CT) scan in patients with minor head injury is lacking in Saudi Arabia. The purpose of the study was to evaluate the compliance and effectiveness of the Canadian computed tomography head rule (CCHR) in our emergency department (ED) and trauma centre and also to reduce the number of unjustified CT studies of the head in the centre. Methods A retrospective study of 368 ED patients with minor head injury was conducted. Patients who underwent CT scan between July 2010 and June 2011were selected from the ED head trauma registry by systematic randomisation. The CCHR was retrospectively applied on the patients’ charts to calculate the prevalence of unjustified head CT scans. A separate survey was conducted to evaluate three emergency physicians’ level of awareness about the CCHR and their ability to determine the necessity of CT scans with various clinical scenarios of head injury. Results The prevalence of unjustified CT scans as per the CCHR was 61.8% (95% confidence interval (CI) 56.5–66.9%). Approximately 5% of the sample had positive CT findings with 95% CI 2.9–7.6%. The CCHR correctly identified 12 cases with positive CT findings with 66.67% sensitivity. Only 24 (6.7%) had Glasgow coma scale scores less than 15 (13/14). The Glasgow coma scale correctly identified only two cases with positive CT findings with 11.11% sensitivity. The percentage of skull fracture (0.9% vs 5%, P = 0.030) was significantly lower in patients with unjustified CT scans than in patients with clinically justified CT scans. There was fair to substantial agreement between the ED physicians and the CCHR (κ = 35–61%). Two ED physicians identified all cases of justified CT scan with 100% sensitivity (95% CI 71.51–100%). Conclusion The level of education regarding the CCHR was found to be optimal among emergency physicians using a case-based scenario survey. The CCHR was found to have a poor compliance potential in the busy ED of our trauma centre and the prevalence of unjustified cranial CT scans remained high. PMID:26471399

Inflicted pediatric head injury is a significant issue in New Zealand, fatal cases receiving extensive media attention. The primary aims of this article were to analyze injury patterns and reported mechanisms against both age and cause (accidental or inflicted). The secondary aims were to quantify these deaths and identify trends over time. We retrospectively reviewed pediatric deaths due to head injury in children younger than 15 years referred to the Coronial Service of Auckland, New Zealand, from January 1, 1991, to December 31, 2010. One hundred sixty-seven cases were identified. Overall incidence was stable over time; however, the rate of inflicted head injury increased significantly (from 0.1 to 0.4/100,000 per year). Evidence of impact was seen in 90% of cases. In children younger than 2 years, in the absence of motor vehicle or pedestrian trauma, subdural hemorrhage and diffuse axonal injury were both highly suggestive of inflicted injury. The absence of a history of trauma or a history of a fall less than 1 m was also highly suggestive of inflicted injury. Retinal hemorrhages in these fatal head injuries were severe in 77% of cases and moderate in the remainder.

Diagnosis of cervical spine injuries (CSI) in multitrauma patients, especially in the presence of head trauma, can be difficult. Identification of risk factors associated with CSI can help avoid missed or delayed diagnosis. Trauma registry study of pedestrian injuries caused by being hit by an automobile. Data abstracted for each patient included age, gender, Glasgow Coma Score on admission, Injury Severity Score, Abbreviated Injury Scale (AIS) for each body area, level of cervical spine injuries, and associated injuries. The incidence of spine injuries was derived for 4 age groups (14 years and younger, 15 to 55 years, 56 to 65 years, and older than 65 years). Logistic regression analysis was performed to identify risk factors associated with CSI. There were 8,401 pedestrian injuries caused by automobiles, and 178 patients (2.1%) had CSI. Incidence of CSI increased with age (0.3% in the age group 14 years and younger, 2.2% in the group 15 to 55 years, 3.7% in the group 56 to 65 years, and 4.4% in the group older than 65 years). Using the youngest age group (14 years and younger) as reference, relative risk of CSI in the other groups was 7.0, 12.1, and 14.2, respectively (p < 0.0001). Patients with severe head trauma (AIS > 3) were significantly more likely to have CSI than patients with less severe head injuries (AIS 3), severe chest trauma (AIS > 3), pelvic fracture, and femur fracture as independent risk factors for CSI. Incidence of CSI after injuries to pedestrians hit by automobiles increases with age and severity of head trauma. Age, severe head trauma, severe chest trauma, pelvic fracture, and femur fractures are independent predictors of CSI.

Trauma is a common cause of death amongst children/adolescents, and data on its epidemiology and pattern are crucial for policy formulation. The aim of this study was to determine the epidemiology and pattern of paediatric/adolescent trauma death in a Nigerian referral trauma centre. The clinical and autopsy data of all paediatric/adolescent trauma death at the University of Benin Teaching Hospital between 1999 and 2010 were analysed in a retrospective study. Of 905 trauma-related deaths, 78 (9%) involved children/adolescents who comprised 49 males and 29 females, with a male/female ratio 1.7:1 and a mean age of 9.2 ± 5 years (range <1-18 years). The Injury-Arrival time varied from 1h to 4 days (mean 18 h). Thirteen (17%) cases were dead on arrival (DOA), and majority of the deaths occurred within the first week on admission. Road traffic accident (RTA), accounting for 61 (78%) cases, was the leading cause of trauma death. Other causes included burns, eight (10%); gunshot injury, five (6%); and stab and sport injuries, two (3%) cases each. Head injury which occurred in 44 (56%) cases was the commonest cause of death, followed by haemorrhagic shock in 25 (32%), hypovolaemic shock in five (6%), septic shock in three (4%) and spinal cord injury in one (1%). Head injury following RTA was the major cause of paediatric/adolescent trauma deaths. Increased road safety campaign, appropriate injury control policies, legislations, enforcement, development of high-quality trauma system, and emergency medical services are advocated.

This case report is intended to inform acute care surgeons about treating rare horizontal laceration of the pancreas head caused by blunt trauma. A 57-year-old woman who sustained blunt abdominal trauma during a car crash was transported to the emergency center of our hospital with unstable vital signs due to hemorrhagic shock. Computed tomography showed transection of the pancreas head and massive intra-abdominal hemorrhage. She was referred for emergency surgery because of a transient response. Laparotomy at five hours after the accident initially revealed consistent massive bleeding from branches of the superior mesenteric artery and vein, which we resolved by suturing the vessels without damaging the main trunks. A horizontal laceration and complete transection of the pancreatic head were then confirmed but the main pancreatic duct remained intact. The lower part of the pancreatic head including the uncus with the attached part of the duodenum was resected, and the pancreatic stump remaining after transection was fixed by suturing. The jejunal limb was attached to the remnant duodenum by side-to-side functional anastomosis. Although gastric emptying was delayed for one month after surgery, the postoperative course was good and the patient recovered at three months thereafter. The embryonic border of pancreas head accompanied with pancreatic divisum was considered for this laceration without disruption of the main pancreatic duct. Blunt pancreatic trauma usually causes vertical transection and thus, horizontal transection is considered rare. The embryological anatomical border between the ventral and dorsal pancreas due to pancreatic divisum was supposed to be transected and therefore the main pancreatic duct was not damaged. Hemorrhagic shock and rare pancreatic head trauma were treated by appropriate intraoperative management. Copyright © 2017 The Author(s). Published by Elsevier Ltd.. All rights reserved.

Severe Acute Subdural Hemorrhage in a Patient With Glutaric Aciduria Type I After Minor Head Trauma: A Case Report.

2015-07-01

Glutaric aciduria type I is a rare metabolic disorder caused by deficiency of glutaryl-coenzyme A dehydrogenase. Chronic subdural hematomas have been reported in glutaric aciduria type I and are considered as important differential diagnosis of nonaccidental head trauma. However, chronic subdural hematomas are usually thought to remain clinically silent in these patients. Here we report on a hitherto asymptomatic glutaric aciduria type I patient who developed severe, acute subdural hemorrhage after minor accidental head injury at age 23 months. Computed tomography confirmed significant mass effect on the brain necessitating decompressive hemicraniectomy. Subdural hemorrhage caused large hypoxic lesions of the cerebral cortex and subcortical regions resulting in spastic tetraplegia, dystonia, and loss of developmental milestones. This report emphasizes that acute subdural hemorrhage may be a life-threatening complication in glutaric aciduria type I patients after minor head trauma and should be considered in those patients presenting with neurologic deterioration after accidental head injury. © The Author(s) 2014.

Objective. To investigate the indications to receive brain computed tomography (CT) scan and to define the pathological findings in children younger than three years of age with minor head trauma in emergency departments. Methods. In this study, hospital case notes of 1350 children attending the emergency department of Bitlis State Hospital between January 2011 and June 2013 were retrospectively reviewed. 508 children under 3 years of age with minor head trauma were included in this study. We also asked 37 physicians about the indications for requiring CT in these children. Results. This study included 508 children, 233 (45,9%) of whom were female and 275 were male. In 476 (93,7%) children, the brain CT was completely normal. 89,2% of physicians asked in the emergency department during that time interval reported that they requested CT scan to protect themselves against malpractice litigation. Conclusion. In infants and children with minor head trauma, most CT scans were unnecessary and the fear of malpractice litigation of physicians was the most common reason for requesting a CT.

Overall mortality ascribable to multiple traumas, that in Italy is responsible for about 8,000 death/year, is strictly dependent on the function of the so called Trauma Care System. This study reports on an epidemiological survey conducted in the urban area of Florence along a 23-month period (from Jan 97 to Nov 99), with the aim to identify the typology of traumas and the first aid care delivered to the person until hospital admission. These data were compared to those collected in the urban area of Bologna because the composition of the first-aid team is different, being nurses, in Bologna, an integral component of the first aid system. On a total of 118 multiple traumas, 17% was represented by isolated head trauma, while in 72% involvement of other organs was present in addition to the head; 11% of cases were abdominal or thoracic traumas, 1% of lower extremities. In 46% the cause of trauma was a car accident. The complexity of care delivered to the person with trauma was less in the Florence survey, as indicated by the immobilization of patients, performed in only 11% of cases as compared to 47% in Bologna, by the application of the cervical collar, applied in 12% versus 62% of traumas. Although the two samples are not strictly comparable, these data suggest that the presence of nurses in the Trauma Care System can be one of the elements of improvement of the quality of delivered care.

Small series have suggested that outcomes after abusive head trauma are less favorable than after other injury mechanisms. We sought to determine the impact of abusive head trauma on mortality and identify factors that differentiate children with abusive head trauma from those with traumatic brain injury from other mechanisms. First 200 subjects from the Approaches and Decisions in Acute Pediatric Traumatic Brain Injury Trial-a comparative effectiveness study using an observational, cohort study design. PICUs in tertiary children's hospitals in United States and abroad. Consecutive children (age < 18 yr) with severe traumatic brain injury (Glasgow Coma Scale ≤ 8; intracranial pressure monitoring). None. Demographics, injury-related scores, prehospital, and resuscitation events were analyzed. Children were dichotomized based on likelihood of abusive head trauma. A total of 190 children were included (n = 35 with abusive head trauma). Abusive head trauma subjects were younger (1.87 ± 0.32 vs 9.23 ± 0.39 yr; p < 0.001) and a greater proportion were female (54.3% vs 34.8%; p = 0.032). Abusive head trauma were more likely to 1) be transported from home (60.0% vs 33.5%; p < 0.001), 2) have apnea (34.3% vs 12.3%; p = 0.002), and 3) have seizures (28.6% vs 7.7%; p < 0.001) during prehospital care. Abusive head trauma had a higher prevalence of seizures during resuscitation (31.4 vs 9.7%; p = 0.002). After adjusting for covariates, there was no difference in mortality (abusive head trauma, 25.7% vs nonabusive head trauma, 18.7%; hazard ratio, 1.758; p = 0.60). A similar proportion died due to refractory intracranial hypertension in each group (abusive head trauma, 66.7% vs nonabusive head trauma, 69.0%). In this large, multicenter series, children with abusive head trauma had differences in prehospital and in-hospital secondary injuries which could have therapeutic implications. Unlike other traumatic brain injury populations in children, female predominance was seen in abusive head trauma in our cohort. Similar mortality rates and refractory intracranial pressure deaths suggest that children with severe abusive head trauma may benefit from therapies including invasive monitoring and adherence to evidence-based guidelines.

Traumatic injuries of the abducens nerve as a consequence of facial and/or head trauma occur with or without associated cervical or skull base fracture. This is the first report on unilateral avulsion of the abducens nerve in a 29-year-old man with severe right facial trauma. In addition, he exhibited mild left facial palsy, and moderate left hearing disturbance. Magnetic resonance imaging (MRI) using fast imaging employing steady-state acquisition (FIESTA) revealed avulsion of left sixth cranial nerve. We recommend thin-slice MR examination in patients with abducens palsy after severe facial and/or head trauma.

Basal ganglia infarction in young children, mostly after mild head trauma, has been repeatedly reported. The pathogenesis and the risk factors are not fully understood. Lenticulostriate vasculopathy, usually referred to as basal ganglia calcification, is discussed as one of them. We describe five young (7-13 months old on presentation) male children who suffered from hemiparesis due to ischemic stroke of the basal ganglia, four of them after minor head trauma. All of them had calcification in the basal ganglia visible on computed tomography or cranial ultrasound but not on magnetic resonance imaging. Follow-up care was remarkable for recurrent infarction in three patients. One patient had a second symptomatic stroke on the contralateral side, and two patients showed new asymptomatic infarctions in the contralateral basal ganglia on imaging. In view of the scant literature, this clinic-radiologic entity seems under recognized. We review the published cases and hypothesize that male sex and iron deficiency anemia are risk factors for basal ganglia stroke after minor trauma in the context of basal ganglia calcification in infants. We suggest to perform appropriate targeted neuroimaging in case of infantile basal ganglia stroke, and to consider prophylactic medical treatment, although its value in this context is not proven.

Fatal subarachnoid hemorrhage associated with internal carotid artery dissection resulting from whiplash trauma.

2015-12-01

Spinal injury following inertial loading of the head and neck (whiplash) is a common sequel of low speed traffic crashes. A variety of non-musculoskeletal injuries have been described in association with injury to the spine following whiplash trauma, including traumatic brain injury, vestibular derangement, and cranial nerve injury, among others. Vascular injuries in the head and neck have, however, only rarely been described. We present the case of a middle-aged male who sustained an ultimately fatal injury that resulted from injury to the internal carotid artery (ICA) and intracerebral vascular structures following a hard braking maneuver, with no direct head- or neck contact with the vehicular interior. Based on this unusual mechanism of injury we reviewed hospital data from the United States nationwide inpatient database (NIS) to assess the frequency of similar injuries reportedly resulting from traffic crashes. The post-mortem examination revealed a left internal carotid artery dissection associated with subarachnoid hemorrhage (SAH). Based on the close temporal association, the absent prior history, and the plausibility of the injury mechanism, the injury was attributed to the braking maneuver. An analysis of NIS data demonstrated that the prevalence of subarachnoid hemorrhage is significantly higher when there is a traumatic etiology, and higher yet when the trauma is a traffic crash (odds ratio 3.3 and 4.3, respectively). The presented case, together with the hospital inpatient data analysis, indicate that although SAH in combination with ICA dissection is relatively rare, it is substantially more probable following a traffic crash. In a clinical or forensic setting the inference that magnitude of a trauma was low should not serve as a basis for either excluding a cervical artery dissection from a differential diagnosis, or for excluding the trauma as a cause of a diagnosed dissection. This case report illustrates a rare fatal outcome of inertial load to the head and neck induced by a sudden braking event in a commonly experienced non-collision traffic incident. The likely mechanism of injury resulted from interaction between the occupant and the 3-point seat belt. These findings indicate that ICA dissections are substantially more likely to be associated with SAH following head and neck trauma, regardless of the magnitude of the traumatic event or whether an impact was involved.

Use of a forensic technique to identify blood contamination of emergency department and ambulance trauma equipment.

Using a Kastle-Meyer (KM) technique, the following equipment from the emergency departments of six UK hospitals (four trusts) and three regional ambulance services was tested for blood contamination: extrication ("spinal") boards, cervical collars, straps, box splints, head blocks, and headboards. Only equipment ready for patient use was tested. Over half of trauma equipment (57%) tested positive for blood, including 15% of equipment that was visibly stained with blood. There have been no recorded cases of infection from contaminated trauma equipment but our study has identified the potential risk. Disposable covers for boards, disposable straps, and disposable radiolucent head blocks which are currently available provide a solution but have resource implications.

Prospective assessment of concomitant lumbar and chronic subdural hematoma: is migration from the intracranial space involved in their manifestation?

Spinal subdural hematomas (SDHs) are rare and some are concomitant with intracranial SDH. Their pathogenesis and etiology remain to be elucidated although their migration from the intracranial space has been suggested. The authors postulated that if migration plays a major role, patients with intracranial SDH may harbor asymptomatic lumbar SDH. The authors performed a prospective study on the incidence of spinal SDH in patients with intracranial SDH to determine whether migration is a key factor in their concomitance. The authors evaluated lumbar MR images obtained in 168 patients (125 males, 43 females, mean age 75.6 years) with intracranial chronic SDH to identify cases of concomitant lumbar SDH. In all cases, the lumbar MRI studies were performed within the 1st week after surgical irrigation of the intracranial SDH. Of the 168 patients, 2 (1.2%) harbored a concomitant lumbar SDH; both had a history of trauma to both the head and the hip and/or lumbar area. One was an 83-year-old man with prostate cancer and myelodysplastic syndrome who suffered trauma to his head and lumbar area in a fall from his bed. The other was a 70-year-old man who had hit his head and lumbar area in a fall. Neither patient manifested neurological deficits and their hematomas disappeared under observation. None of the patients with concomitant lumbar SDH had sustained head trauma only, indicating that trauma to the hip or lumbar region is significantly related to the concomitance of SDH (p < 0.05). As the incidence of concomitant lumbar and intracranial chronic SDH is rare and both patients in this study had sustained a direct impact to the head and hips, the authors suggest that the major mechanism underlying their concomitant SDH was double trauma. Another possible explanation is hemorrhagic diathesis and low CSF syndrome.

During an eight year period 170 multiple sclerosis (MS) patients and 134 controls without physical impairment were followed closely to record all episodes of physical trauma and to measure their effect on exacerbation rate and progression of MS. There was a total of 1407 instances of trauma, which were sorted into various categories. Overall there was no significant correlation between all-traumas and disease activity. There was, however, a statistically significant negative correlation between traumatic episodes and exacerbations in 95 patients who had exacerbations during the programme, due primarily to less activity of the disease during a three month period following surgical procedures and fractures. Electrical injury had a significant positive association with exacerbation using a three month at-risk period, but there were no other significant positive correlations in any other category of trauma, including minor head injuries; there were no cases of head injury with prolonged unconsciousness. There was no linkage between the frequency of trauma and progression of disability. MS patients had two to three times more trauma than controls. PMID:1895121

We present the case of a 44-year-old man with bilateral otic capsule violating temporal bone fractures due to head trauma. The patient demonstrated much improved audiometric and psychoacoustic performance after bilateral cochlear implantation. We believe bilateral cochlear implantation in such patient can be a very effective tool for rehabilitation. Copyright © 2011 Elsevier Inc. All rights reserved.

SU-F-SPS-03: Direct Measurement of Organ Doses Resulting From Head and Cervical Spine Trauma CT Protocols

DOE Office of Scientific and Technical Information (OSTI.GOV)

Carranza, C; Lipnharski, I; Quails, N

Purpose: This retrospective study analyzes the exposure history of emergency department (ED) patients undergoing head and cervical spine trauma computed tomography (CT) studies. This study investigated dose levels received by trauma patients and addressed any potential concerns regarding radiation dose issues. Methods: Under proper IRB approval, a cohort of 300 trauma cases of head and cervical spine trauma CT scans received in the ED was studied. The radiological image viewing software of the hospital was used to view patient images and image data. The following parameters were extracted: the imaging history of patients, the reported dose metrics from the scannermore » including the volumetric CT Dose Index (CTDIvol) and Dose Length Product (DLP). A postmortem subject was scanned using the same scan techniques utilized in a standard clinical head and cervical spine trauma CT protocol with 120 kVp and 280 mAs. The CTDIvol was recorded for the subject and the organ doses were measured using optically stimulated luminescent (OSL) dosimeters. Typical organ doses to the brain, thyroid, lens, salivary glands, and skin, based on the cadaver studies, were then calculated and reported for the cohort. Results: The CTDIvol reported by the CT scanner was 25.5 mGy for the postmortem subject. The average CTDIvol from the patient cohort was 34.1 mGy. From these metrics, typical average organ doses in mGy were found to be: Brain (44.57), Thyroid (33.40), Lens (82.45), Salivary Glands (61.29), Skin (47.50). The imaging history of the cohort showed that on average trauma patients received 26.1 scans over a lifetime. Conclusion: The average number of scans received on average by trauma ED patients shows that radiation doses in trauma patients may be a concern. Available dose tracking software would be helpful to track doses in trauma ED patients, highlighting the importance of minimizing unnecessary scans and keeping doses ALARA.« less

A case of severe organic affective disorder after head trauma with loss of consciousness is presented. While CT in this case was normal, SPECT brain perfusion imaging showed hipoperfusion in the right frontal lobe and the left temporal-parietal region. The psychologic tests: Benton, Bender, MMPI confirmed changes in CNS as well. These findings help to explain the severity and chronicity of disorders and medical certification.

Management of trauma-induced chronic torticollis in raptors has historically been challenging. Euthanasia is common in affected birds because of their inability to maintain normal cervical position, although they may be able to function normally. To assess effectiveness of physical therapy of the neck and head as an adjunct treatment for this condition, a case-control study was done in raptors admitted to the Rocky Mountain Raptor Program from 2003 to 2010. Eleven cases were identified with a diagnosis of chronic torticollis resulting from traumatic brain injury. Five cases were treated with physical therapy of the head and neck, and 6 control cases did not receive any physical therapy for the torticollis. Of the control cases, 0 of 6 had resolution of the torticollis, 0 of 6 were released, and 5 of 6 were euthanatized. Of the treated cases, 4 of 5 had complete resolution of the torticollis and 5 of 5 were released. Resolution of torticollis differed significantly between cases receiving physical therapy and controls. These results indicate that physical therapy should be used as an adjunctive therapy in cases of chronic torticollis induced by trauma in raptors because it results in better resolution of the torticollis and increased likelihood of release.

Fatal pediatric head injury due to toppled television: does the injury pattern overlap with abusive head trauma?

PubMed

Kodikara, Sarathchandra; Pollanen, Michael

2012-07-01

Pediatric head injuries can occur from abusive head trauma (AHT) or accidents. Accidental pediatric head injuries caused by cathode-ray tube televisions (CRTT) toppling have become a 'silent epidemic'. Differentiation between a fatal case of AHT and CRTT toppling could be vexing when the historical and scene evidence are subtle. A 2-year-old girl was found unresponsive in her house and could not be resuscitated. A 27" CRTT was found fallen from its stand onto the floor at the scene. The siblings report that the deceased was climbing on the television stand when it toppled. Autopsy revealed a spectrum of head injuries including, contusions, fractures, bilateral acute subdural hemorrhages, subarachnoid hemorrhages, brain contusion-lacerations and corpus callosal hemorrhages. Microscopy of the eyes revealed bilateral acute retinal hemorrhages. The cause of death was given as crushing injuries of head and brain. The skull fracture pattern is compatible with an accident causing crush injury due to the toppled CRTT rather than AHT. The injury pattern reconfirms that the head is the most vulnerable site in case of CRTT tipover. Although there may be an overlap between the injury pattern in AHT and in CRTT tipover cases, a careful evaluation of the history and scene and autopsy findings such as the crushing nature of the skull fractures and distribution of injury, can solve this problem.

Head injury is the leading cause of death and long term disability from bicycle injuries and may be prevented by helmet wearing. We compared the pattern of injury in major trauma victims resulting from bicyclist injury admitted to hospitals in the State of Victoria, Australia and South-West Netherlands, with respective high and low prevalence of helmet use among bicyclists. A cohort of bicycle injured patients with serious injury (defined as Injury Severity Score>15) in South-West Netherlands, was compared to a cohort of serious injured bicyclists in the State of Victoria, Australia. Additionally, the cohorts of patients with serious injury admitted to a Dutch level 1 trauma centre in Rotterdam, the Netherlands and an Australian level 1 trauma centre in Melbourne, Australia were compared. Both cohorts included patients admitted between July 2001 and June 2009. Primary outcome was in-hospital mortality and secondary outcome was prevalence of severe injury per body region. Outcome was compared using univariate analysis and mortality outcomes were also calculated using multivariable logistic regression models. A total of 219 cases in South-West Netherlands and 500 cases in Victoria were analyzed. Further analyses comparing the major trauma centres in each region, showed the percentage of bicycle-related death was higher in the Dutch population than in the Australian (n=45 (24%) vs n=13(7%); P<0.001). After adjusting for age, mechanism of injury, GCS and head injury severity in both hospitals, there was no significant difference in mortality (adjusted odds ratio 1.4; 95% confidence interval=0.6, 3.5). Patients in Netherlands trauma centre suffered from more serious head injuries (Abbreviated Injury Scale≥3) than patients in the Australian trauma centre (n=165 (88.2%) vs n=121 (62.4%); P<0.001). The other body regions demonstrated significant differences in the AIS scores with significantly more serious injuries (AIS≥3) of the chest, abdominal and extremities regions in the Australian group. Bicycle related major trauma admissions in the Netherlands trauma centre, and in South-West Netherlands had a higher mortality rate associated with a higher percentage of serious head injuries compared with that in the Australian trauma centre and the State of Victoria.

2006-01-01

Using a Kastle‐Meyer (KM) technique, the following equipment from the emergency departments of six UK hospitals (four trusts) and three regional ambulance services was tested for blood contamination: extrication (“spinal”) boards, cervical collars, straps, box splints, head blocks, and headboards. Only equipment ready for patient use was tested. Over half of trauma equipment (57%) tested positive for blood, including 15% of equipment that was visibly stained with blood. There have been no recorded cases of infection from contaminated trauma equipment but our study has identified the potential risk. Disposable covers for boards, disposable straps, and disposable radiolucent head blocks which are currently available provide a solution but have resource implications PMID:16373813

The aim of this study was to investigate epidemiological features of maxillofacial fractures within trauma patients who had head and neck computed tomography (CT) scan at the Mulago National referral hospital. CT scan records of trauma patients who had head scans at the Department of Radiology over 1-year period were accessed. Data collected included sociodemographic factors, type and etiology of injury, and concomitant maxillofacial injuries. A total of 1330 trauma patients underwent head and neck CT scan in the 1-year study period. Out of these, 130 were excluded due to incomplete or unclear records and no evidence of injury. Of the remaining 1200, 32% (387) had maxillofacial fractures. The median age of the patients with maxillofacial fractures was 28 (range = 18-80) years and 18-27 age group was most common at 47.5%. Road traffic accidents constituted 49.1% of fractures. The single most affected isolated bone was the frontal bone (23%). The number of maxillofacial bones fractured was predicted by age group (df = 3 F = 5.358, P = 0.001), association with other fractures (df = 1 F = 5.317, P = 0.03). Good matched case-control prospective studies are needed to enable us tease out the finer difference in the circumstances and pattern of injury if we are to design appropriate preventive measures.

Colloid cyst mimicking intracranial hemorrhage after head trauma.

2015-02-01

Trauma patients consist vast majority of the patients who admit to emergency department, and most of them have a head trauma. A 58-year-old patient was taken to emergency department with head trauma, and a hyperdense lesion neighboring to third ventricle was detected. A diagnosis of colloid cyst was made in the patient who was being followed up for hemorrhage. In patients with head trauma, colloid cyst may easly be confused with intracranial hemorrhage due to hyperdensity. The aim of this report is to emphasize the importance of clinical thinking in the differential diagnosis of hyperdense lesion on computed tomography imaging of a patient with head injury.

This study examines non-accidental trauma (NAT) fatalities as a percentage of all injury fatalities and identifies injury patterns in NAT admissions to two level 1 pediatric trauma centers. We reviewed all children (<5years old) treated for NAT from 2011 to 2015. Patient demographics, injury sites, and survival were obtained from both institutional trauma registries. Of 4623 trauma admissions, 557 (12%) were due to NAT. However, 43 (46%) of 93 overall trauma fatalities were due to NAT. Head injuries were the most common injuries sustained (60%) and led to the greatest increased risk of death (RR 5.1, 95% CI 2.0-12.7). Less common injuries that increased the risk of death were facial injuries (14%, RR 2.9, 95% CI 1.6-5.3), abdominal injuries (8%, RR 2.8, 95% CI 1.4-5.6), and spinal injuries (3%, RR 3.9, 95% CI 1.8-8.8). Although 76% of head injuries occurred in infants <1year, children ages 1-4years old with head injuries had a significantly higher case fatality rate (27% vs. 6%, p<0.001). Child abuse accounts for a large proportion of trauma fatalities in children under 5years of age. Intracranial injuries are common in child abuse and increase the risk of death substantially. Preventing NAT in infants and young children should be a public health priority. Retrospective Review. II. Copyright © 2018. Published by Elsevier Inc.

Computed tomography pattern of traumatic head injury in Niger Delta, Nigeria: A multicenter evaluation

PubMed Central

Onwuchekwa, Chinwe Regina; Alazigha, Nengi S.

2017-01-01

Background and Purpose: Traumatic head injury has a high mortality and morbidity in low- and middle-income countries. Brain injury following trauma is the cause of death in about one-third of patients that die after trauma. The aim of the study was to assess the pattern of computed tomography (CT) findings in head trauma at the tertiary health institutions serving the Niger Delta region of Nigeria. Patients and Methods: The CT scans of the head of 310 consecutive patients referred specifically for evaluation of head injury were prospectively reviewed. The images acquired were analyzed by the radiologists. The radiological features and anatomical distribution of the lesions on the CT Images were assessed and documented. Patients with congenital abnormalities of the head and those whose fall or injury were secondary to stroke were excluded from the study. The Ethical Committee of our institutions gave approval for the study. Results: There were 225 (72.58%) males and 85 (27.42%) females. About 44.84% of the patients were in the third and fourth decades of life. The major causes of head injury were road traffic accidents in 67.74%, falls in 14.84%, and assaults in 7.42%. Most of the patients 102 (33.0%) presented within the 1st week of injury. Cranial fractures were found in 87 (28.06%) patients. In this series, 111 (35.81%) had normal CT findings while 199 (64.19%) had abnormal CT findings. Intra-axial lesions were the most common, constituting 131 (42.26%) cases. Conclusion: This study had demonstrated that majority of head trauma evaluated by CT were associated with cranial and brain injuries. Intra-axial injuries are more prevalent. Poor health facilities and bad road networks in addition to being risk factors for head injury also hamper the management of head-injured patients as shown by the long duration of injury before health facilities are accessed.

2017-12-01

Abusive head trauma (AHT) is a potentially fatal result of child abuse, but the mechanisms by which injury occur are often unclear. To investigate the contention that shaking alone can elicit the injuries observed, effective computational models are necessary. The aim of this study was to develop a probabilistic model describing infant head kinematics in AHT. A deterministic model incorporating an infant's mechanical properties, subjected to different shaking motions, was developed in OpenSim. A Monte Carlo analysis was used to simulate the range of infant kinematics produced as a result of varying both the mechanical properties and the type of shaking motions. By excluding physically unrealistic shaking motions, worst-case shaking scenarios were simulated and compared to existing injury criteria for a newborn, a 4.5 month-old, and a 12 month-old infant. In none of the three cases were head kinematics observed to exceed previously-estimated subdural haemorrhage injury thresholds. The results of this study provide no biomechanical evidence to demonstrate how shaking by a human alone can cause the injuries observed in AHT, suggesting either that additional factors, such as impact, are required, or that the current estimates of injury thresholds are incorrect.

Traumatic brain injury (TBI) is a frequent health problem and increased prevalence of neurendocrine dysfunction in patients with TBI has been reported. Sports injuries and particularly boxing may result in pituitary dysfunction. However, transient hypogonadotropic hypogonadism after an acute head trauma due to boxing and/or kickboxing has not been defined yet. We describe the case of a 20-yr-old male amateur kickboxer who was admitted to hospital complaining of decreased libido and impotence 2 weeks after an intensive bout. Basal hormone levels were compatible with mild hyperprolactinemia and hypogonadotpopic hypogonadism. GH axis was evaluated by GHRH+GHRP-6 test and peak GH level was within normal reference range. Three months later his complaints improved and abnormalities in basal hormone levels normalized. He was also re-evaluated 9 months after the first evaluation; basal hormone levels were within normal ranges and he had no complaints. In conclusion acute head trauma due to kickboxing may cause transient gonadotropin deficiency. Therefore, screening the pituitary functions of sportsmen dealing with combative sports is crucial.

The objective of the study was an assessment of the occurrence of traumatic cerebral lesions and skull fractures in patients with mild head trauma. A total of 171 patients' notes, 89 male (52%) and 82 female (48%), mean age 48 years, were subjected to analysis. Of the 171 patients, in 58 (34%) CT scanning of the head was not performed for various reasons, and these patients were discharged home. Of the remaining 113 persons, who had head CT performed, in 99 (88%) no abnormalities were found; in 10 (9%) CT scans revealed pathological findings unrelated to the trauma: most frequently cortical-subcortical atrophy followed by old post-stroke foci, and in 4 patients (3%) post-traumatic pathologies: skull fractures in 2 and facial bone fractures in 2. Diagnosis of these fractures did not change the conservative treatment of these patients, but only prolonged in-patient stay for 2-3 days. All skull and facial bone fractures occurred in patients who were alcohol intoxicated, were lying, could not maintain vertical position, or who had the "racoon eyes" sign. The results of our study show that lack of abnormalities in neurological examination in patients after mild head injury is a reliable indicator for omitting CT scanning, because the risk of overlooking brain injuries in these patients is minimal. However, patients who are intoxicated, have problems with maintaining a vertical position and have the "racoon eyes" sign, are likely to have skull or facial fractures, and CT scanning is therefore justified. Considering these precursors (guidelines) and the use of clinical decision rules described in the article may reduce the number of head CT scans performed "just in a case".

Venous air embolism: An under-recognised entity in blunt-force trauma and the importance of radiology.

PubMed

du Plessis, Marna; du Toit-Prinsloo, Lorraine

2017-04-01

Air embolism (AE) is considered a rare event and can be either iatrogenic or traumatic. Various post-mortem methods to detect AE exist, of which radiology is preferred. The presence of air in the heart can be demonstrated using special dissection techniques where the heart is opened under water or by needle puncture from a water-filled syringe. Three cases of blunt-force head injury are presented herein, with AE being diagnosed by conventional radiography using a Lodox Statscan® full-body digital X-ray machine in all cases. This case series demonstrates that AE due to blunt-force trauma to the head and sinuses might be under-recognised in the forensic post-mortem setting. It also highlights the importance of radiology in diagnosing AE post-mortem, especially where the results of post-mortem techniques might be unsatisfactory.

Children presenting in delayed fashion after minor head trauma with scalp swelling: do they require further workup?

It is common to evaluate children who have sustained minor head trauma with computed tomography (CT) of the head. Scalp swelling, in particular, has been associated with intracranial injury. A subset of patients, however, present in delayed fashion, often days after the head trauma, as soft tissue edema progresses and their caregiver notices scalp swelling. We explore the value of further workup in this setting. We conducted a retrospective review of a prospectively collected cohort of children ≤24 months of age presenting to the Texas Children's Hospital with scalp swelling more than 24 h following a head trauma. Cases were collected over a 2-year study period from June 1, 2014 to May 31, 2016. Seventy-six patients comprising 78 patient encounters were included in our study. The mean age at presentation was 8.8 months (range 3 days-24 months). All patients had noncontrast CT of the head as part of their evaluation by emergency medicine, as well as screening for nonaccidental trauma (NAT) by the Child Protection Team. The most common finding on CT head was a linear/nondisplaced skull fracture (SF) with associated extra-axial hemorrhage (epidural or subdural hematoma), which was found in 31/78 patient encounters (40%). Of all 78 patient encounters, 43 patients (55%) were discharged from the emergency room (ER), 17 patients (22%) were admitted for neurologic monitoring, and 18 patients (23%) were admitted solely to allow further NAT evaluation. Of those patients admitted, none experienced a neurologic decline and all had nonfocal neurologic exams on discharge. No patient returned to the ER in delayed fashion for a neurologic decline. Of all the patient encounters, no patient required surgery. Pediatric patients ≤24 months of age presenting to the ER in delayed fashion with scalp swelling after minor head trauma-who were otherwise nonfocal on examination-did not require surgical intervention and did not experience any neurologic decline. Further radiographic investigation did not alter neurosurgical management in these patients; however, it should be noted that workup for child abuse and social care may have been influenced by CT findings, suggesting the need for the future development of a clinical decision-making tool to help safely avoid CT imaging in this setting.

Head injury is often associated with psychiatric morbidity. While it is well understood that the loss of critical areas of the brain may play a role in cognitive dysfunction and change in personality, head injury can also have profound effects on mood and cognition. The role of medications in the treatment of mood disorders associated with brain injury is well documented, and there is also evidence favoring the use of electroconvulsive therapy (ECT) in this context. However, data are limited on the use of ECT in patients with skull defects or metallic head implants. First, a review of the literature on use of ECT in patients with metallic head implants is provided. Electronic databases and online sites, including PubMed, Cochrane Library of Systematic Reviews, and UpToDate, were used to search for relevant articles and case reports on the use of ECT in patients with and without metallic implants in the head (1964 to 2009). The search terms electroconvulsive, electroconvulsive therapy, ECT, electroshock therapy, EST, head injury, brain injury, metallic plates, metallic implants, skull prosthesis, and depression were used interchangeably. The search produced 7 articles discussing exclusively the use of ECT in patients with a metallic skull plate. Second, the case of the successful and safe use of ECT in an individual with a previous history of brain trauma and metallic plate implantation is described. Most cases of head injury are managed by neurologists and rehabilitation consultants; the more severe cases of depression and other mood disorders tend to be referred for specialist psychiatric care. With greater degrees of deficit following head injury, management becomes more complicated. Our patient showed positive results with ECT, including improvement in depressive features and resolution of suicidal ideas/plans. ECT is an effective and safe alternative in patients with a history of brain trauma and metallic plate implantation who subsequently develop treatment-resistant depression and associated suicidal ideas or plans refractory to management with medications.

One Stage Emergency Pancreatoduodenectomy  for Isolated Injury to Pancreatic Head Following Blunt Abdominal Trauma: Case Report and Review of Literature.

PubMed

Ghosh, Sumanta Kumar

2013-07-01

Major pancreatic injury following blunt abdominal trauma by itself is a relatively rare occurrence, and in vast majority of cases (95%) it is associated with injury to adjacent major vessels and organs; thus making isolated major pancreatic injury even rarer. While most pancreatic injuries are managed by simple measures like debridement and drainage, complex proximal injury poses surgical challenge regarding surgical skill and judgement. Disproportionate approach at any stage of management can contribute  to high mortality and morbidity. Emergency pancreatoduodenectomy plays a limited but important role in managing serious trauma to proximal pancreas and duodenum. Author presents a case where isolated injury to head of pancreas required emergency pancreatoduodenectomy. After a bizarre road accident, a middle aged male underwent emergency laparotomy for intraperitoneal bleeding and during exploration a deep transverse laceration with ampullary disruption was found in the head of the organ. Duodenum in all its part was intact and there was no other injury. The nature and site of injury made emergency pancreatoduodenectomy the only viable option. Leaking pancreatojejunostomy enhances infective complications that lead to late mortality. To circumvent this problem there is enthusiasm for staged surgery with resection and tube pancreatostomy in first stage, leaving the difficult anastomosis for a later date, However, if the patient is haemodynamically stable and operated reasonably early, one stage pancreatoduodenectomy gives good result and avoids repeating surgery with inherent problems and reduces hospital stay. For successful management of pancreatic trauma it is essential to make early diagnosis of duct disruption, with sound application of operative skill and judgement by treating surgeon.

AIM: This study aimed to make a retrospective analysis of pediatric patients with head traumas that were admitted to one hospital setting and to make an analysis of the patients for whom follow-up CT scans were obtained. METHODS: Pediatric head trauma cases were retrospectively retrieved from the hospital’s electronic database. Patients’ charts, CT scans and surgical notes were evaluated by one of the authors. Repeat CT scans for operated patients were excluded from the total number of repeat CT scans. RESULTS: One thousand one hundred and thirty-eight pediatric patients were admitted to the clinic due to head traumas. Brain CT scan was requested in 863 patients (76%) in the cohort. Follow-up brain CT scans were obtained in 102 patients. Additional abnormal finding requiring surgical intervention was observed in only one patient (isolated 4th ventricle hematoma) on the control CTs (1% of repeat CT scans), who developed obstructive hydrocephalus. None of the patients with no more than 1 cm epidural hematoma in its widest dimension and repeat CT scans obtained 1.5 hours after the trauma necessitated surgery. CONCLUSION: Follow-up CT scans changed clinical approach in only one patient in the present series. When ordering CT scan in the follow-up of pediatric traumas, benefits and harms should be weighted based upon time interval from trauma onset to initial CT scan and underlying pathology.

Head trauma is the main cause of disabilities and death among young people, and the side effects of head trauma pose some of the greatest medical challenges. Rapid diagnosis and the use of proper treatments can prevent more severe brain damage. The purpose of this research was to determine the quality of nursing services provided to brain trauma patients in hospitals in Guilan Province, Iran. The study was conducted as a descriptive, cross-sectional study in the emergency wards of selected hospitals in Guilan in 2012. The research population was comprised of all the brain trauma patients in these hospitals. We developed a two-section questionnaire, ascertained its validity, and determined that it had a reliability of 88% (Cronbach's alpha). Subsequently, we used the questionnaire for gathering data. The data were analyzed using SPSS statistical software, and descriptive analysis tests (frequency rate and average) and deductive analyses tests (chi-squared) also were used. The results showed that the quality of health services provided to brain-trauma patients in the emergency ward was at the moderate level of 58.8% of the cases and at a low level in 41.2% of the cases. Based on the results that showed that the services were of moderate quality, the staff members in the emergency ward were required to update their knowledge and use the required measures to minimize or prevent side effects in brain-trauma patients; clearly, mastery of such measures was a real need among the emergency ward's staff.

Review of pancreatic trauma.

PubMed Central

Glancy, K E

1989-01-01

In reviewing the literature on pancreatic trauma (1,984 cases), I found that it resulted from penetrating trauma in 73% and blunt trauma in 27% of cases. Associated injuries were common (average 3.0 per patient). Increased mortality was associated with shotgun wounds, an increasing number of associated injuries, the proximity of the injury to the head of the pancreas, preoperative shock, and massive hemorrhage. High mortality was found for total pancreatectomy, duct reanastomosis, and lack of surgical treatment, with lower mortality for Roux-en-Y anastomoses, suture and drainage, distal pancreatectomy, and duodenal exclusion and diverticulization techniques. Most patients required drainage only. The preoperative diagnosis of pancreatic trauma is difficult, with the diagnosis usually made during surgical repair for associated injuries. Blood studies such as amylase levels, diagnostic peritoneal lavage, and plain radiographs are not reliable. Computed tomographic scanning may be superior, but data are limited. PMID:2669347

Concussion in Chronic Traumatic Encephalopathy

Stein, Thor D.; Alvarez, Victor E.; McKee, Ann C.

2015-01-01

Chronic traumatic encephalopathy (CTE) is a progressive neurodegenerative disease that occurs in association with repetitive mild traumatic brain injury. It is associated with a variety of clinical symptoms in multiple domains, and there is a distinct pattern of pathological changes. The abnormal tau pathology in CTE occurs uniquely in those regions of the brain that are likely most susceptible to stress concentration during trauma. CTE has been associated with a variety of types of repetitive head trauma, most frequently contact sports. In cases published to date, the mean length of exposure to repetitive head trauma was 15.4 years. The clinical symptoms of the disease began after a mean latency of 14.5 years with a mean age of death of 59.3 years. Most subjects had a reported history of concussions with a mean of 20.3. However, 16 % of published CTE subjects did not have a history of concussion suggesting that subconcussive hits are sufficient to lead to the development of CTE. Overall, the number of years of exposure, not the number of concussions, was significantly associated with worse tau pathology in CTE. This suggests that it is the chronic and repetitive nature of head trauma, irrespective of concussive symptoms, that is the most important driver of disease. CTE and exposure to repetitive head trauma is also associated with a variety of other neurodegenerations, including Alzheimer disease. In fact, amyloid β peptide deposition is altered and accelerated in CTE and is associated with worse disease. Here, we review the current exposure, clinical, and pathological associations of CTE.

To evaluate the computed tomography (CT) findings of intracranial hemorrhage among patients with head trauma in Lagos, Nigeria. In this retrospective, cross-sectional study, a convenience sample of 500 patients with head trauma who had diagnostic cranial CT scans was selected. All the radiological reports and CT scans of patients with head trauma were retrieved in the hospitals selected as study sites. The reports were sorted into 2 groups - normal findings and intracranial bleeding. The reports of intracranial bleeding were sorted again into different classes of intracranial bleeding as identified by the radiologist who reported it. All data were analyzed using the Epi Info public domain software package. The chi-square test was used to measure the statistical significance of study results at P < .05. Most of the study subjects (68%) were men. Traffic accidents accounted for 44% of all the head traumas found in the study, and 58% of the head traumas resulted in intracranial bleeding. Among the hemorrhages found, 37% were intracerebral, 25% were subdural, 16% were intraventricular, 15% were subarachnoid, and 7% were epidural. Intracranial hemorrhage was a common consequence of acute head trauma sustained from traffic accidents in the population studied, with intracerebral hemorrhage being the most prevalent type. Traffic accidents are the main cause of acute head trauma in Lagos, Nigeria. The use of CT for early diagnosis of intracranial hemorrhage appears justifiable.

MR imaging with sedation is commonly used to detect intracranial traumatic pathology in the pediatric population. Our purpose was to compare nonsedated ultrafast MR imaging, noncontrast head CT, and standard MR imaging for the detection of intracranial trauma in patients with potential abusive head trauma. A prospective study was performed in 24 pediatric patients who were evaluated for potential abusive head trauma. All patients received noncontrast head CT, ultrafast brain MR imaging without sedation, and standard MR imaging with general anesthesia or an immobilizer, sequentially. Two pediatric neuroradiologists independently reviewed each technique blinded to other modalities for intracranial trauma. We performed interreader agreement and consensus interpretation for standard MR imaging as the criterion standard. Diagnostic accuracy was calculated for ultrafast MR imaging, noncontrast head CT, and combined ultrafast MR imaging and noncontrast head CT. Interreader agreement was moderate for ultrafast MR imaging (κ = 0.42), substantial for noncontrast head CT (κ = 0.63), and nearly perfect for standard MR imaging (κ = 0.86). Forty-two percent of patients had discrepancies between ultrafast MR imaging and standard MR imaging, which included detection of subarachnoid hemorrhage and subdural hemorrhage. Sensitivity, specificity, and positive and negative predictive values were obtained for any traumatic pathology for each examination: ultrafast MR imaging (50%, 100%, 100%, 31%), noncontrast head CT (25%, 100%, 100%, 21%), and a combination of ultrafast MR imaging and noncontrast head CT (60%, 100%, 100%, 33%). Ultrafast MR imaging was more sensitive than noncontrast head CT for the detection of intraparenchymal hemorrhage ( P = .03), and the combination of ultrafast MR imaging and noncontrast head CT was more sensitive than noncontrast head CT alone for intracranial trauma ( P = .02). In abusive head trauma, ultrafast MR imaging, even combined with noncontrast head CT, demonstrated low sensitivity compared with standard MR imaging for intracranial traumatic pathology, which may limit its utility in this patient population. © 2017 by American Journal of Neuroradiology.

Glutaric aciduria type 1 (GA1) is a rare metabolic disorder of glutaryl-CoA-dehydrogenase enzyme deficiency. Children with GA1 are reported to be predisposed to subdural hematoma (SDH) development due to stretching of cortical veins secondary to cerebral atrophy and expansion of CSF spaces. Therefore, GA1 testing is part of the routine work-up in abusive head trauma (AHT). This systematic review addresses the coexistence of GA1 and SDH and the validity of GA1 in the differential diagnosis of AHT. A systematic literature review, with language restriction, of papers published before 1 Jan 2015, was performed using Pubmed, PsychINFO, and Embase. Inclusion criteria were reported SDHs, hygromas or effusions in GA1 patients up to 18 years of age. Of 1599 publications, 20 publications were included for analysis. In total 20 cases, 14 boys and 6 girls, were included. In eight cases (40%) a child abuse work-up was performed, which was negative in all cases. Clinical history revealed the presence of trauma in eight cases (40%). In only one case neuroradiology revealed no abnormalities related to GA1 according to the authors, although on evaluation we could not exclude AHT. From this systematic review we conclude that SDHs in 19/20 children with GA1 are accompanied by other brain abnormalities specific for GA1. One case with doubtful circumstances was the exception to this rule.

Chiari malformation is defined as herniation of the cerebellar tonsils through the foramen magnum, also known as cerebellar tonsillar ectopia (CTE). CTE may become symptomatic following whiplash trauma. The purpose of the present study was to assess the frequency of CTE in traumatic vs non-traumatic populations. Case-control. Cervical MRI scans for 1200 neck pain patients were reviewed; 600 trauma (cases) and 600 non-trauma (controls). Half of the groups were scanned in a recumbent position and half were scanned in an upright position. Two radiologists interpreted the scans for the level of the cerebellar tonsils. A total of 1195 of 1200 scans were read. CTE was found in 5.7% and 5.3% in the recumbent and upright non-trauma groups vs 9.8% and 23.3% in the recumbent and upright trauma groups (p = 0.0001). The results described in the present investigation are first to demonstrate a neuroradiographic difference between neck pain patients with and without a recent history of whiplash trauma. The results of prior research on psychosocial causes of chronic pain following whiplash are likely confounded because of a failure to account for a possible neuropathologic basis for the symptoms.

As the availability of imaging modalities has increased, the finding of arachnoid cysts has become common. Accurate patient counseling regarding physical activity or risk factors for cyst rupture or hemorrhage has been hampered by the lack of definitive association studies. This case-control study evaluated factors that are associated with arachnoid cyst rupture (intracystic hemorrhage, adjacent subdural hematoma, or adjacent subdural hygroma) in pediatric patients with previously asymptomatic arachnoid cysts. Patients with arachnoid cysts and intracystic hemorrhage, adjacent subdural hygroma, or adjacent subdural hematoma treated at a single institution from 2005 to 2010 were retrospectively identified. Two unruptured/nonhemorrhagic controls were matched to each case based on patient age, sex, anatomical cyst location, and side. Risk factors evaluated included arachnoid cyst size, recent history of head trauma, and altitude at residence. The proportion of imaged arachnoid cysts that presented either originally or subsequently with a rupture or hemorrhage was 6.0%. Larger cyst size, as defined by maximal cyst diameter, was significantly associated with cyst rupture/hemorrhage (P < .001). When dichotomized with a 5-cm cutoff, 9/13 larger cysts ruptured and/or hemorrhaged, whereas only 5/29 smaller cysts ruptured/hemorrhaged (odds ratio = 16.5 (confidence interval [2.5, ∞]). A recent history of head trauma was also significantly associated with the outcome (P < .001; odds ratio = 25.1 (confidence interval [4.0, ∞]). Altitude was not associated with arachnoid cyst rupture or hemorrhage. This case-control study suggests that larger arachnoid cyst size and recent head trauma are risk factors for symptomatic arachnoid cyst rupture/hemorrhage.

It is unclear whether trauma patients should be transferred initially to a trauma center or local hospital. A systematic review and meta-analysis assessed the evidence for direct transport to specialist centers (SCs) versus initial stabilization at non-SCs (NSCs) for major trauma or moderate-to-severe head injury. Nine databases were searched from 1988 to 2012. Limitations in the study design informed recommendations for future studies. Of 19 major trauma studies, five (n = 19,910) included patients not transferred to SCs and adjusted for case mix. Meta-analysis showed no difference in mortality for initial triage to NSCs versus SCs (odds ratio [OR] 1.03; 95% confidence interval [CI], 0.85-1.23). Within studies excluding patients not transferred to SCs, unadjusted analyses of mortality nonsignificantly favored transfer via NSCs (16 studies; n = 37,079; OR, 0.83; 95% CI, 0.68-1.01), whereas adjusted analysis nonsignificantly favored direct triage to SCs (9 studies; n = 34,266; OR, 1.18; 95% CI, 0.96-1.44). Of 11 head injury studies, all excluded patients not transferred to SCs and half were in remote locations. There was no significant mortality difference between initial triage to NSCs versus SCs within adjusted analyses (3 studies; n = 1,507; OR, 0.74; 95% CI, 0.31-1.79) or unadjusted analyses (10 studies; n = 3,671; OR, 0.87; 95% CI, 0.62-1.23). This systematic review demonstrated no difference in outcomes for direct transport to a trauma center versus initial triage to a local hospital. Many studies had significant limitations in the design, and heterogeneity was high. Recommendations for future studies include the following: (i) inclusion of patients not transferred to SCs and those dying during transport; (ii) clear description of centers plus transport distances/times; (iii) adjustments for case mix; and (iv) assessment of morbidity and mortality. Systematic review, level IV.

Chronic Traumatic Encephalopathy: A Potential Late Effect of Sport-Related Concussive and Subconcussive Head Trauma1

Gavett, Brandon E.; Stern, Robert A.; McKee, Ann C.

2010-01-01

Synopsis Chronic traumatic encephalopathy (CTE) is a form of neurodegeneration that is believed to result from repeated head injuries. Originally termed dementia pugilistica due to its association with boxing, the neuropathology of CTE was first described by Corsellis in 1973 in a case series of 15 retired boxers. CTE has recently been found to occur following other causes of repeated head trauma, suggesting that any repeated blows to the head, such as those that occur due to American football, hockey, soccer, professional wrestling, and physical abuse, can also lead to neurodegenerative changes. These changes often include cerebral atrophy, cavum septum pellucidum with fenestrations, shrinkage of the mammillary bodies, dense tau immunoreactive inclusions (neurofibrillary tangles, glial tangles, and neuropil neurites), diffuse axonal injury, and, in some cases, a TDP-43 proteinopathy. In association with these pathological changes, affected individuals often exhibit disordered memory and executive functioning, behavioral and personality disturbances (e.g., apathy, depression, irritability, impulsiveness, suicidality), parkinsonism, and, occasionally, motor neuron disease. At the present time, there are no formal clinical or pathological diagnostic criteria for CTE, but the distinctive neuropathological profile of the disorder lends promise for future research into its prevention, diagnosis, and treatment.

Temple trauma that appears initially localized to the skin might possess intracranial complications. Early diagnosis and management of such complications are important, to avoid neurologic sequelae. Non-penetrating head injuries with intracranial hemorrhage caused by a driven bone fragment are extremely rare. A 53-year-old male was referred to our hospital because of intracerebral hemorrhage. He was a mechanic and one day before admission to a local clinic, tip of metallic rod hit his right temple while cutting the rod. Initial brain computed tomography (CT) and magnetic resonance imaging demonstrated scanty subdural hematoma at right temporal lobe and left falx and intracerebral hematoma at both frontal lobes. Facial CT with 3-D reconstruction images showed a small bony defect at the right sphenoid bone's greater wing and a small bone fragment at the left frontal lobe, crossing the falx. We present the unusual case of a temple trauma patient in whom a sphenoid bone fragment migrated from its origin upward, to the contralateral frontal lobe, producing hematoma along its trajectory.

Mild traumatic brain injury: a risk factor for neurodegeneration

PubMed Central

2010-01-01

Recently, it has become clear that head trauma can lead to a progressive neurodegeneration known as chronic traumatic encephalopathy. Although the medical literature also implicates head trauma as a risk factor for Alzheimer's disease, these findings are predominantly based on clinical diagnostic criteria that lack specificity. The dementia that follows head injuries or repetitive mild trauma may be caused by chronic traumatic encephalopathy, alone or in conjunction with other neurodegenerations (for example, Alzheimer's disease). Prospective longitudinal studies of head-injured individuals, with neuropathological verification, will not only improve understanding of head trauma as a risk factor for dementia but will also enhance treatment and prevention of a variety of neurodegenerative diseases.

Update on child abuse prevention.

Child abuse remains a significant problem in the United States with 2.9 million reports and 825 000 indicated cases in 2005. This report will highlight recent efforts toward child abuse prevention, focusing on home visiting programs, abusive head trauma primary prevention, parent training programs, sexual abuse prevention, and the effectiveness of laws banning corporal punishment. Most home visitation programs have demonstrated a lack of effectiveness in recent randomized trials. One exception is the Nurse Family Partnership, which remains the most effective and longest enduring intervention for high-risk families. Child sexual abuse prevention programs and parent training programs need further evaluation with more rigorous methodology and outcome measures. Providing universal parent education about coping with crying infants appears to be effective in lowering the incidence of abusive head trauma. Although advocated for, further study will determine the effectiveness of laws banning corporal punishment or mandating abusive head trauma education to parents of newborns. Pediatricians play an important role in the prevention of child maltreatment. Their knowledge of the effectiveness of different programs can help guide parents toward appropriate services.

Spasm of accommodation associated with closed head trauma.

PubMed

Chan, R V Paul; Trobe, Jonathan D

2002-03-01

Spasm of accommodation, creating pseudomyopia, is generally associated with miosis and excess convergence as part of spasm of the near reflex. It may also exist as an isolated entity, usually attributed to psychogenic causes. We present six cases of accommodative spasm associated with closed head injury. All patients were male, ranging in age between 16 and 37 years. The degree of pseudomyopia, defined as the difference between manifest and cycloplegic refraction, was 1.5 to 2 diopters. A 3-year trial of pharmacologically induced cycloplegia in one patient did not lead to reversal of the spasm when the cycloplegia was stopped. All patients required the manifest refraction to see clearly at distance. The pseudomyopia endured for at least 7 years following head trauma. This phenomenon may represent traumatic activation or disinhibition of putative brain stem accommodation centers in young individuals.

[Biomechanical aspects of cervical trauma].

Walz, F; Meine, J

The biomechanical expert opinion on the injury mechanism is necessary in few cases only. However, the judgement of these cases is extremely compromised if mechanically wrong terms are introduced in the clinical report. Since the injury mechanism in the neck is very complex the clinical physician should concentrate on the clinical findings familiar to him; usually the clinician lacks technical case documentation and specific training in injury biomechanics. The relevant mechanisms of neck injuries are an indirect trauma induced by a) a head contact leading to compression, hyperflexion, hyperextension and/or hypertranslation and b) a non-head-contact mechanism (hyperflexion or hyperextension, hypertranslation, acceleration). A non-contact mechanism occurs e.g. during a rear end impact without head restraint (hyperextension) or a frontal collision of a belted occupant (hyperflexion) without head impact. The term "whiplash" is misleading and incorrect: It presumes a virtually non existing two phase movement back and forth (or vice versa) like during the development of the crack of the whip. Secondly, it mixes the physical criterion mechanism with the anatomical or morphological criterion injury e.g. distortion, sprain etc. A (head)-contact mechanism is due to a corresponding momentum exerted from the head on the neck. Again, the anatomical or morphological terms are equal, but the mechanism is different. During a contact mechanism as well as during a non-contact mechanism not only a hyperflexion or a hyperextension can occur; in the first phase of the impact also a shearing force between the upper vertebral bodies (CO-C2) may load the intervertebral structures by hypertranslation.

Aneurysm of gastroduodenal artery (GDA) is rare. Most reported cases are due to pancreatitis and atherosclerosis; however, those following pancreatic trauma have not been reported. We encoun- tered GDA aneurysm in a patient of blunt abdominal trauma, who had pancreatic contusion and retroduodenal air on contrast enhanced computed tomography of abdomen. Emergency laparotomy for suspected duodenal injury revealed duodenal wall and pancreatic head contusion, mild hemo- peritoneum and no evidence of duodenal perforation. In the postoperative period, the patient developed upper gastrointestinal hemorrhage on day 5. Repeat imaging revealed GDA aneurysm, which was managed successfully by angioembolization. This case highlights, one, delayed presen- tation of GDA aneurysm after blunt pancreatic trauma and two, its successful management using endovascular technique.

Arachnoid cysts are a relatively common finding in adult patients, especially with the advent of advanced imaging techniques. The overall incidence ranges from 1-2%, and the majority are clinically silent 1,2 . Arachnoid cysts are postulated to arise by congenital anomalies or trauma 1 . De novo formation of arachnoid cysts has been reported, but is exceptionally rare and mostly found in the pediatric population after head trauma 3-5 . There have only been two reported cases of symptomatic de novo arachnoid cyst formation in adult patients to date, both with histories of head trauma 6,7 . We present a case of a 71-year-old male patient with progressive vertigo who had previous brain MRI studies without abnormalities. Another MRI was performed three years from the last study that showed interval development of a large cystic lesion compressing the right cervicomedullary junction, as well as radiologic evidence of neurosarcoidosis. Intraoperative findings showed a cystic mass with clear, gelatinous fluid. The cyst was drained and the walls were resected and sent to pathology. Histopathologic testing confirmed the lesion was an arachnoid cyst. The patient's vertiginous symptoms improved after surgery. This case represents the first incidence of a pathology proven, non-traumatic de novo arachnoid cyst. Copyright © 2018 Elsevier Inc. All rights reserved.

Injuries resulting from trauma are over-represented in Bahrain's intensive care unit beds. Using data from 1984 and 1985, this study examines the most severe etiologic agents and high-risk population groups among ICU trauma patients. Road traffic accidents were the principal cause of admission, accounting for 57% of all injury admissions. Most occurred in pedestrians suffering from severe head injury. Poisonings were the second largest category, followed by falls. In comparison with medical cases admitted to the ICU during the same 2-year period, the trauma cases included a disproportionate number of children and males in their most productive years of life, further adding to the economic burden which injuries have inflicted on this small country. The authors call for a new approach, namely passive prevention such as environmental modifications and legislation and tertiary prevention such as improvement of the country's underutilized ambulance service.

Head injuries are described in the literature as a rare but possible etiology of cerebral venous thrombosis although no pathophysiological link has been identified. Trauma-related venous thrombi occurring in the brain produce a broad spectrum of clinical presentations. A purely psychiatric term is exceptional, leading to misinterpretation and late diagnosis. Positive diagnosis has been greatly improved by advances in magnetic resonance imaging with venous phase angiography, currently the gold standard exploration. We report the case of a patient who presented with post-trauma cerebral venous thrombosis revealed by psychiatric disorders. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

Prehospital assessment of injury type and severity by emergency medical services physicians impacts treatment including appropriate destination hospital selection, especially in (potentially) life-threatening cases. Injuries which are underestimated or overlooked by the emergency physician can delay adequate therapy and thus significantly influence the overall outcome. The current study used data from the TraumaRegister DGU® to evaluate the reliability of prehospital injury assessments made by emergency physicians. Data of 30,777 patients from the TraumaRegister DGU® between 1993 and 2009 were retrospectively evaluated. Using the abbreviated injury scale (AIS), subjective prehospital assessments of injury severity by emergency physicians were correlated with objectively identified injuries diagnosed after admission to hospital. For this evaluation, prehospital injury assessments rated moderate or severe by the emergency physician as well as injuries diagnosed in hospital with an AIS score ≥3 points were deemed relevant. The 30,777 patients with an injury severity score (ISS) ≥ 9 suffered a total of 202,496 injuries and of these 26 % (51,839 out of 202,496) were considered relevant with an AIS ≥3 points. The most frequent relevant injuries were to the head (47 %) and chest (46 %). Of the 51,839 relevant injuries, the prehospital assessment by the emergency physician was accurate for 71 % and in 29 % of the cases relevant injuries were underestimated. Relevant injuries were unrecognized or underestimated in prehospital assessments for almost 1 out of every 7 cases of head trauma, almost 1 out of every 3 thoracic trauma and almost 1 out of every 2 abdominal and pelvic trauma. The assessment of injury severity by emergency medical services physicians based on physical examination at the scene of the trauma is not very reliable. Thus, mechanisms of injury and overall presentation as well as identifiable injuries and vital parameters should be recognized by the emergency physician when considering treatment strategies and choice of appropriate destination hospital. The patient should be re-evaluated in a priority-oriented manner at the latest on arrival in the trauma room to avoid the consequences of unrecognized or underestimated injuries.

Juvenile delinquents often show poor impulse control and cognitive abnormalities, which may be related to disturbances in brain development due to head trauma and/or epilepsy. The aim of the present study was to examine the influence of head trauma and/or epilepsy on delinquent behavior. We examined 1,336 juvenile delinquents (1,151 males and 185 females) who had been admitted to the Nagoya Juvenile Classification Home, Aichi, Japan. Among them, 52 subjects with a history of epilepsy, convulsion or loss of consciousness, head injury requiring neurological assessment and/or treatment, or neurosurgical operation (head trauma/epilepsy group), were examined by electroencephalography and compared to subjects without these histories (control group) with respect to types of crime, history of amphetamine use, psychiatric treatment, child abuse, and family history. Among the 52 subjects, 43 (82.7%) showed abnormal findings. The head trauma/epilepsy group had significantly higher rates of psychiatric treatment (P<0.0001, OR=16.852, 95% CI=8.068-35.199) and family history of drug abuse (P<0.05, OR=2.303, 95% CI=1.003-5.290). Furthermore, the percentage of members who were sent to juvenile training school by the family court was significantly higher in the head trauma/epilepsy group (72.5%) than in the control group (38.9%, P<0.0001). The juvenile delinquents who had a history of head trauma and/or epilepsy showed a high prevalence of electroencephalograph abnormality, and higher rates of psychiatric treatment and family history of drug abuse, and were more likely to be sent to juvenile training school by the family court.

For cardio-pulmonary resuscitation there are standardized treatment concepts, but there have been few prospective investigations examining the efficacy of prehospital advanced trauma life support and its effect on the outcome in patients with severe head injury and multiple trauma treated within the German emergency system. The results of this study underline the importance of intensive prehospital treatment and highlight some problems that should be taken into account in future in the training of emergency physicians. METHODS. A total of 179 patients with cerebral trauma were investigated. Data obtained included demographic and logistic data of the patients and the emergency physicians, diagnoses and treatment at the scene of the accident and state of the patient on admission in each case. Having divided the patients into three groups by severity of the trauma, we distinguished between sufficient and insufficient treatment and assessed infusion therapy, ventilatory support, positioning and immobilization, and analgesic and sedative therapy. For statistical analysis of the data we used chi 2-test and Fisher's exact test. P < 0.05 was considered significant. RESULTS. There were 102 patients who had sustained a cerebral trauma without other life-threatening lesions (score 1), 40 with multiple trauma (score 2) and 37 with multiple trauma (score 3). On average 2.4 IV lines were established and the patients received 1186 +/- 765 cc of crystalloid in addition to 801 +/- 411 cc of colloid fluids. In all groups, patients who received adequate infusion therapy had a better outcome; even in the group with score 1 significantly fewer had a fatal outcome. In all, 167 (93%) patients had endotracheal tubes placed, and in 150 cases (84%) ventilatory therapy was considered sufficient. The proportion of score 1 patients with sufficient ventilatory support who had a fatal outcome was significantly lower than that in the group with insufficient treatment. In patients with multiple trauma we could not separate the benefits of sufficient respiratory therapy and infusion therapy. In only 54% of the cases a vacuum mattress was used and in only 41% the patients were positioned with the upper part of the body elevated by 30 degrees. These were 28 patients (16%) who received neither analgesics nor sedatives. Regardless of the quality of prehospital treatment of isolated head injury, a Glasgow Coma Scale (GCS) score lower than 5 involved a very high mortality and all patients with a GCS score of 9 or more survived. In the group with GCS scores between 5 and 8, however, significantly more of the patients who received adequate treatment survived (82.5% vs 40%). CONCLUSIONS. The present study confirms that sufficient advanced trauma life support can improve the outcome of trauma victims with cerebral trauma. Adequate infusion and respiratory therapy reduce the mortality among such patients significantly. In patients with multiple trauma a clear positive effect of generous infusion therapy also is evident. The clearest effect of sufficient prehospital treatment is seen in patients with isolated cerebral trauma and a GCS score between 5 and 8. These results demonstrate the importance of advanced trauma life support and show emphatically that the so-called scoop-and-run strategy should be abandoned when resources are available for extended preclinical emergency treatment. On the other hand, we detected some problem areas in the prehospital treatment of trauma victims, such as positioning, immobilization and drug therapy with analgesics and sedatives. These findings allow us to pinpoint specific points that should be stressed in the training of emergency physicians and paramedics.

Background: A 14-year-old, previously healthy male athlete suffered 4 head traumas over a 4-month period. The first 3 traumas were considered by the athlete to be minor and were not reported to medical personnel. The fourth trauma was a medically diagnosed concussion suffered during soccer play. Over the next year, the patient noted a decline in strength and conditioning and a failure to grow. Differential Diagnosis: After physical examination and a full battery of endocrine tests, the patient, then 16.5 years old, was diagnosed with hypopituitarism. Follow-up interviews provided evidence that at least 2 of the 3 head injuries suffered before the last concussion could also be considered concussions, which may have contributed to the severity of the last head injury. Treatment: The patient is currently being treated with physiologic replacement hormones (growth hormone, cortisol, and thyroxine), with resumption of linear growth and strength. He is progressing well. Uniqueness: In the past few years in the medical literature, increased attention has been drawn to the occult occurrence of hypopituitarism after traumatic brain injury in adults. Initial reports indicate that children are also at risk. To our knowledge, this is the first reported case of hypopituitarism after mild traumatic brain injury in the sports medicine literature. Conclusions: Symptoms of hypopituitarism are often masked by trauma and postconcussion symptoms and may not appear until months or years after the trauma incident, which can lead to significant delay in proper diagnosis and treatment. We urge greater vigilance by, and training of, sports medicine clinicians toward the goal of recognizing the possibility of pituitary disorders after sports concussion. PMID:18060001

An underestimated evaluation of systemic organs in cases with spinal fractures might jeopardize the intervention for treatment and future complications with an increased morbidity and mortality are almost warranted. In the present study, a retrospective analysis of spinal fracture cases associated with systemic trauma was performed to assess surgical success. A retrospective analysis of patients with thoracolumbar fractures who were admitted to the emergency unit between September 2012 and September 2014 was used for the study. The cases were categorized according to age, sex, reason of trauma, associated trauma, neurological condition and treatment details and results were analysed using SPSS 14.0 for Windows. The most common reason of trauma is detected as falls in 101 cases (64.3%). Radiological evaluation of spinal fractures revealed a compression fracture in 106 cases (67.5%) and other fractures in 51 cases (32.5%). Surgical treatment for spinal fracture was performed in 60.5% of the cases and conservative approach was preferred in 39.5% cases. In non-compressive spinal fractures, an associated pathology like head trauma, lower extremity fracture or neurological deficit was found to be higher in incidence (p < 0.05). Necessity for surgical intervention was found to be more prominent in this group (p < 0.05). However, the fracture type was not found to be associated with morbidity and mortality (p < 0.05). A surgical intervention for a spinal fracture necessitating surgery should rather be performed right after stabilization of the systemic condition which might be associated with decreased morbidity and mortality.

Thoracic trauma is one of the leading causes of morbidity and mortality in developing countries. In this study, we present our 11-year experience in the management and clinical outcome of 888 chest trauma cases as a result of blunt and penetrating injuries in our university hospital in Damascus, Syria. We reviewed files of 888 consequent cases of chest trauma between January 2000 and January 2011. The mean age of our patients was 31 ± 17 years mostly males with blunt injuries. Patients were evaluated and compared according to age, gender, etiology of trauma, thoracic and extra-thoracic injuries, complications, and mortality. The leading cause of the trauma was violence (41%) followed by traffic accidents (33%). Pneumothorax (51%), Hemothorax (38%), rib fractures (34%), and lung contusion (15%) were the most common types of injury. Associated injuries were documented in 36% of patients (extremities 19%, abdomen 13%, head 8%). A minority of the patients required thoracotomy (5.7%), and tube thoracostomy (56%) was sufficient to manage the majority of cases. Mean hospital LOS was 4.5 ± 4.6 days. The overall mortoality rate was 1.8%, and morbidity (n = 78, 8.7%). New traffic laws (including seat belt enforcement) reduced incidence and severity of chest trauma in Syria. Violence was the most common cause of chest trauma rather than road traffic accidents in this series, this necessitates epidemiologic or multi-institutional studies to know to which degree violence contributes to chest trauma in Syria. The number of fractured ribs can be used as simple indicator of the severity of trauma. And we believe that significant neurotrauma, traffic accidents, hemodynamic status and GCS upon arrival, ICU admission, ventilator use, and complication of therapy are predictors of dismal prognosis.

Optimal management of penetrating pancreaticoduodenal injuries and better outcomes are associated with simple, fast damage control surgery and shorter operative time. The performance of pyloric exclusion and tube duodenostomy has markedly decreased. However, there is still a trend toward their performance in cases of delay duodenal repair or severe pancreaticoduodenal injury. The present report describes a case of a hemodynamically stable patient with a single penetrating gunshot trauma causing an AAST-OIS grade III pancreatic head injury and grade IV injury of the second portion of the duodenum. The patient was treated in our Level IV rural trauma center and submitted to primary closure of the posterolateral duodenal wall (the laceration of the contralateral inner medial duodenal wall could not be repaired), external duodenal and pancreatic drainage, and duodenal decompression by tube pancreatico-duodenostomy (insertion of a 18 Fr Foley catheter through the laceration of the pancreatic head toward the duodenal lumen), tube cholangiostomy, and pyloric exclusion accompanied with a feeding jejunostomy. Tube pancreatico-duodenostomy, which is described for the first time in the literature, turned out to be effective and can be considered as an option in pancreaticoduodenal trauma when the inner medial duodenal wall cannot be repaired.

Criteria for CT and Initial Management of Head Injured Infants: A Review

Criteria for computed tomography (CT) to head injured infants have not been established. Since the identification of neurological findings is difficult in infants, examination by CT may be necessary in some cases, but it may be difficult to perform CT because of problems with radiation exposure and body movement. Moreover, even though no intracranial abnormality was found immediately after injury, abnormal findings may appear after several hours. From this viewpoint, course observation after injury may be more important than CT in the initial treatment of head trauma in infants. The complaints and neurological manifestations of infants, particularly those aged 2 or younger, are frequently unclear; therefore, there is an opinion that CT is recommended for all pediatric patients. However, the appropriateness of its use should be determined after confirming the mechanism of injury, consciousness level, neurological findings, and presence/absence of a history of abuse. Among the currently available rules specifying criteria for CT of infants with head trauma, the Pediatric Emergency Care Applied Research Network (PECARN) study may be regarded as reliable at present. In Japan, where the majority of emergency hospitals are using CT, it may be necessary to develop criteria for CT in consideration of the actual situation. CT diagnosis for pediatric head trauma is not always necessary. When no imaging is performed, this should be fully explained at the initial treatment before selecting course observation at home. Checking on a state of the patients by telephone is useful for both patients and physicians. PMID:27194179

Chronic Effects of Mild Neurotrauma: Putting the Cart Before the Horse?

PubMed Central

Castellani, Rudy J.; Perry, George; Iverson, Grant L.

2015-01-01

Accumulation of phosphorylated tau (p-tau) is accepted by many as a long-term consequence of repetitive mild neurotrauma, based largely on brain findings in boxers (dementia pugilistica) and, more recently, former professional athletes, military service members, and others exposed to repetitive head trauma. The pathogenic construct is also largely accepted and suggests that repetitive head trauma (typically concussions or subconcussive forces) acts on brain parenchyma to produce a deleterious neuroinflammatory cascade, encompassing p-tau templating, trans-synaptic neurotoxicity, progressive neurodegenerative disease, and associated clinical features. Some caution before accepting these concepts and assumptions is warranted, however. The association between history of concussion and findings of p-tau at autopsy is unclear. Concussions and subconcussive head trauma exposure are poorly defined in available cases and the clinical features reported in CTE are not at present distinguishable from other disorders. Because control groups are limited, the idea that p-tau drives the disease process via protein templating or some other mechanism is preliminary. Much additional research in CTE is needed to determine if it has unique neuropathology and clinical features, the extent to which the neuropathologic alterations cause the clinical features, and whether it can be identified accurately in a living person.

The goal of this case-control study was to identify the significance of consanguinity and other risk factors for epilepsy in Oran, Algeria. Unrelated epileptic patients upwards of 16 years, who attended the Neurology Department between October 2013 and March 2014 were included in the study. Controls, matched for age and sex, were selected among non-epileptic patients attending the same department during the same period. The risk factors evaluated were: consanguinity, family history of epilepsy, perinatal complications, infection of the central nervous system, mental retardation, neurological impairment, history of febrile seizures, severe head trauma, cerebrovascular diseases, and addiction. 101 cases and 202 controls participated in the study. Multivariate logistic regression identified five factors significantly associated with epilepsy: first-degree of consanguinity (odds ratio (OR)=2.15), history of epilepsy in first-degree relatives (OR=4.03), antecedent of febrile seizures (OR=5.38), severe head injury (OR=2.94) and mental retardation (OR=9.32). Consanguinity, family history of epilepsy, history of febrile seizures, severe head trauma and mental retardation are risk factors for epilepsy. The implementation of a strategy for prevention and awareness of the impact of consanguineous marriages as well as genetic counseling for couples with a family history of epilepsy are needed.

Diffuse axonal injury by assault.

Imajo, T; Challener, R C; Roessmann, U

1987-09-01

A case of diffuse axonal injury (DAI) by assault is reported. The majority of DAI cases documented have been due to traffic accidents and some due to falls from height. DAI is caused by angular or rotational acceleration of the victim's head. The condition is common and is the second most important head injury after subdural hematoma with regard to death. Its clinical picture is characterized by immediate and prolonged coma or demented state. Because of the subtle nature of histological changes in DAI, awareness and intentional search for the lesion is essential. The triad of DAI is as follows: focal lesions (hemorrhages and/or lacerations) in the corpus callosum and brain stem, and microscopic demonstration of axonal damage--retraction balls. The concept of DAI will elucidate and enhance the understanding of many head trauma cases.

Comprehensive head and neck trauma screening: the USS Cole experience.

A prospective study was designed to determine the incidence of occult head and neck injuries after initial triage of patients following the USS Cole terrorist bombing. All 39 patients evacuated to Landstuhl Regional Medical Center underwent comprehensive head and neck examinations, regardless of known diagnoses at the time of arrival. Appropriate interventions were performed, and detailed summaries were added to the patients' records. Initial triage listed nine of 39 patients as having sustained head and neck injuries. After screening by an otolaryngology team, 23 of 39 patients were identified as having head and neck injuries requiring further care. The majority of head and neck injuries were not initially reported to the head and neck trauma service. Our conclusion is that occult head and neck injuries are common after blast injuries. Early identification and intervention by a subspecialty head and neck trauma team can aid in achieving optimal outcomes after blast injury.

Cranial computed tomography (CT) scans are frequently obtained in the evaluation of blunt head trauma in children. These scans may detect unexpected incidental findings. The objectives of this study were to determine the prevalence and significance of incidental findings on cranial CT scans in children evaluated for blunt head trauma. This was a secondary analysis of a multicenter study of pediatric blunt head trauma. Patients <18 years of age with blunt head trauma were eligible, with those undergoing cranial CT scan included in this substudy. Patients with coagulopathies, ventricular shunts, known previous brain surgery or abnormalities were excluded. We abstracted radiology reports for nontraumatic findings. We reviewed and categorized findings by their clinical urgency. Of the 43,904 head-injured children enrolled in the parent study, 15,831 underwent CT scans, and these latter patients serve as the study cohort. On 670 of these scans, nontraumatic findings were identified, with 16 excluded due to previously known abnormalities or surgeries. The remaining 654 represent a 4% prevalence of incidental findings. Of these, 195 (30%), representing 1% of the overall sample, warranted immediate intervention or outpatient follow-up. A small but important number of children evaluated with CT scans after blunt head trauma had incidental findings. Physicians who order cranial CTs must be prepared to interpret incidental findings, communicate with families, and ensure appropriate follow-up. There are ethical implications and potential health impacts of informing patients about incidental findings.

To collect and compare the results of medical, child protective, and law enforcement evaluation of a sample of Maine children who were victims of abusive head trauma (AHT) in order to describe the clinical and evaluative characteristics as they relate to victims, families and perpetrators of such trauma and to improve the professional response to AHT in Maine. Retrospective chart review of medical, child protective, and law enforcement records of all AHT victims admitted to two tertiary care hospitals in Maine or seen by the state medical examiner from 1991 to 1994. Nineteen children (age range 2 weeks to 17 months) were identified as victims of AHT (out of a total of 94 head trauma admissions) accounting for 20 hospitalizations during the study period. There was a history of prior injury in 30%, history of prior medical evaluations for possibly abuse related problems in 65%, while, on presentation, 75% had evidence or history of prior injury. The hospitals notified child protective services (CPS) in all 20 cases and correctly identified abuse in 18 (90%). Parental risk factors for abuse identified in CPS records included substance abuse (53%), domestic violence (42%), criminal history (32%), unrealistic expectations (42%), and attachment problems (32%). However, risk factors were inadequately assessed in 53% of homes. Law enforcement identified a likely perpetrator in 79% of cases and in the majority the identified suspect was the father. In the 15 cases where a perpetrator was identified by law enforcement, that person was alone with the child at symptom onset in 14 (93%). The medical response, at least at the inpatient level, was generally well done with regard to suspicion and reporting. Cases are possibly being missed at the outpatient level. Child protective risk assessment was limited overall yet in a third of the homes where AHT occurred, few if any risk factors were present to aid in identification and prevention. Law enforcement results suggest that a primary suspect for AHT is the caretaker alone with the child at the time of symptom onset.

Domestic violence is an extremely underreported crime and a growing social problem in the United States. However, the true burden of the problem remains unknown. To assess the reported prevalence of domestic violence among trauma patients. A 6-year (2007-2012) retrospective analysis of the prospectively maintained National Trauma Data Bank. Trauma patients who experienced domestic violence and who presented to trauma centers participating in the National Trauma Data Bank were identified using International Classification of Diseases, Ninth Revision diagnosis codes (995.80-995.85, 995.50, 995.52-995.55, and 995.59) and E codes (E967.0-E967.9). Patients were stratified by age into 3 groups: children (≤18 years), adults (19-54 years), and elderly patients (≥55 years). Trend analysis was performed on April 10, 2014, to assess the reported prevalence of domestic violence over the years. Trauma patients presenting to trauma centers participating in the National Trauma Data Bank. To assess the reported prevalence of domestic violence among trauma patients. A total of 16 575 trauma patients who experienced domestic violence were included. Of these trauma patients, 10 224 (61.7%) were children, 5503 (33.2%) were adults, and 848 (5.1%) were elderly patients. The mean (SD) age was 15.9 (20.6), the mean (SD) Injury Severity Score was 10.9 (9.6), and 8397 (50.7%) were male patients. Head injuries (46.8% of patients) and extremity fractures (31.2% of patients) were the most common injuries. A total of 12 515 patients (75.1%) were discharged home, and the overall mortality rate was 5.9% (n = 980). The overall reported prevalence of domestic violence among trauma patients was 5.7 cases per 1000 trauma center discharges. The prevalence of domestic violence increased among children (14.0 cases per 1000 trauma center discharges in 2007 to 18.5 case per 1000 trauma center discharges in 2012; P = .001) and adults (3.2 cases per 1000 discharges in 2007 to 4.5 cases per 1000 discharges in 2012; P = .001) over the 6-year period and remained unchanged for elderly patients (0.8 cases per 1000 discharges in 2007 to 0.96 cases per 1000 discharges in 2012; P = .09). On subanalysis of adults and elderly patients, the prevalence of domestic violence increased among both female (4.6 cases per 1000 discharges in 2007 to 5.3 cases per 1000 discharges in 2012; P = .001) and male patients (1.5 cases per 1000 discharges in 2007 to 2.8 cases per 1000 discharges in 2012; P = .001). Domestic violence is prevalent among trauma patients. Over the years, the reported prevalence of domestic violence has been increasing among children and adults, and continues to remain high among female trauma patients. A robust mandatory screening for evaluating domestic violence among trauma patients, along with a focused national intervention, is warranted.

Trauma deaths in a mature urban trauma system: is "trimodal" distribution a valid concept?

Trimodal distribution of trauma deaths, described more than 20 years ago, is still widely taught in the design of trauma systems. The purpose of this study was to examine the applicability of this trimodal distribution in a modern trauma system. A study of trauma registry and emergency medical services records of trauma deaths in the County of Los Angeles was conducted over a 3-year period. The times from injury to death were analyzed according to mechanism of injury and body area (head, chest, abdomen, extremities) with severe trauma (abbreviated injury score [AIS] >/= 4). During the study period there were 4,151 trauma deaths. Penetrating trauma accounted for 50.0% of these deaths. The most commonly injured body area with critical trauma (AIS >/= 4) was the head (32.0%), followed by chest (20.8%), abdomen (11.5%), and extremities (1.8%). Time from injury to death was available in 2,944 of these trauma deaths. Overall, there were two distinct peaks of deaths: the first peak (50.2% of deaths) occurred within the first hour of injury. The second peak occurred 1 to 6 hours after admission (18.3% of deaths). Only 7.6% of deaths were late (>1 week), during the third peak of the classic trimodal distribution. Temporal distribution of deaths in penetrating trauma was very different from blunt trauma and did not follow the classic trimodal distribution. Other significant independent factors associated with time of death were chest AIS and head AIS. Temporal distribution of deaths as a result of severe head trauma did not follow any pattern and did not resemble classic trimodal distribution at all. The classic "trimodal" distribution of deaths does not apply in our trauma system. Temporal distribution of deaths is influenced by the mechanism of injury, age of the patient, and body area with severe trauma. Knowledge of the time of distribution of deaths might help in allocating trauma resources and focusing research effort.

Traumatic Brain Injury (TBI) is a major cause of death and disability in our society, we present the first case report of non-missile penetrating (NMP) cranial trauma with a machete in Mexico, and our objective by presenting this case is to prove the usefulness of recently proposed algorithms in the treatment of NMP PRESENTATION OF CASE: We present the case of a 47 year old woman who received a machete hit to the right side of her head during an assault., she arrived fully conscious to the emergency department (ED), computed tomography was performed and based on the findings of this study and in accordance to recently proposed algorithms for managing NMP cranial trauma a craniotomy was performed, at follow-up the patient presented wtih minor neurological disability in the form of left hemiparesis. Non-missile penetrating (NMP) lesions are defined as having an impact velocity of less than 100m/s, causing injury by laceration and maceration, An algorithm for treating NMP cranial trauma has been recently published in the Journal World Neurosurgery by De Holanda et al., in this case we followed the algorithm in order to provide best care available for our patient with good results. The use of current algorithms for managing NMP cranial trauma has proved to be very useful when applied on this particular case. GCS on admission is an important prognostic factor in NMP cranial trauma. Copyright © 2016 The Author(s). Published by Elsevier Ltd.. All rights reserved.

Homer's Iliad is one of the highest intellectual products of the early ancient Greek civilisation. A plethora of medical information lies within Iliad's 24 rhapsodies, and a total of 147 injuries are described. The present study records and evaluates all cases of trauma management included in this epic poem. Not only Iliad's original text but also all myths related to Iliad from the five-volume Greek Mythology by Ioannis Kakridis were meticulously studied to locate the injured person, the type of trauma, the care provider and the type of given care as well as the outcome of each case. A total of 21 cases were found and evaluated with a 5% mortality rate. The majority of these injuries were caused by an arrow (43%) and were located to the upper extremity (43%). Injuries of the head, neck and trunk were not treated as all of them were lethal. Many of the recorded trauma management techniques can be correlated to modern medicine. Furthermore, the role and skills of military doctors and paramedics, mentioned by Homer, is discussed. © 2016 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

Stability of the Giliberty bipolar hip: report of three cases.

PubMed

Langan, P; Weiss, C A

1978-01-01

The Giliberty Bipolar Hip Prosthesis consists of an unbonded acetabular cup which snap-fits over the head of the femoral prosthesis. Because of the free movement permitted at the cup-pelvic junction as well as at the snap-fit interface, there has been a great deal of concern over the potential for dislocation. Three patients in whom this unit was implanted sustained significant skeletal trauma subsequent to surgery. None of them dislocated. In each case the prosthetic head was known to be in a relatively vertical orientation with respect to the transverse axis of the pelvis prior to the injury. In 2 of the 3 cases radiographically identifiable movement of the cup was present before and after the injury. These observations suggest that the persistently mobile, vertically positioned unbonded cup remain stable despite the stress of significant trauma. It is probable that the potential for cup movement, even where on the X-ray it appears to have stopped, acts as a safety valve in absorbing force that might otherwise dislocate the hip or cause fractures of the femur or the pelvis.

Severe-to-fatal head injuries in motor vehicle environments were analyzed using the United States Crash Injury Research and Engineering Network database for the years 1997-2006. Medical evaluations included details and photographs of injury, and on-scene, trauma bay, emergency room, intensive care unit, radiological, operating room, in-patient, and rehabilitation records. Data were synthesized on a case-by-case basis. X-rays, computed tomography scans, and magnetic resonance images were reviewed along with field evaluations of scene and photographs for the analyses of brain injuries and skull fractures. Injuries to the parenchyma, arteries, brainstem, cerebellum, cerebrum, and loss of consciousness were included. In addition to the analyses of severe-to-fatal (AIS4+) injuries, cervical spine, face, and scalp trauma were used to determine the potential for head contact. Fatalities and survivors were compared using nonparametric tests and confidence intervals for medians. Results were categorized based on the mode of impact with a focus on head contact. Out of the 3178 medical cases and 169 occupants sustaining head injuries, 132 adults were in frontal (54), side (75), and rear (3) crashes. Head contact locations are presented for each mode. A majority of cases clustered around the mid-size anthropometry and normal body mass index (BMI). Injuries occurred at change in velocities (DeltaV) representative of US regulations. Statistically significant differences in DeltaV between fatalities and survivors were found for side but not for frontal impacts. Independent of the impact mode and survivorship, contact locations were found to be superior to the center of gravity of the head, suggesting a greater role for angular than translational head kinematics. However, contact locations were biased to the impact mode: anterior aspects of the frontal bone and face were involved in frontal impacts while temporal-parietal regions were involved in side impacts. Because head injuries occur at regulatory DeltaV in modern vehicles and angular accelerations are not directly incorporated in crashworthiness standards, these findings from the largest dataset in literature, offer a field-based rationale for including rotational kinematics in injury assessments. In addition, it may be necessary to develop injury criteria and evaluate dummy biofidelity based on contact locations as this parameter depended on the impact mode. The current field-based analysis has identified the importance of both angular acceleration and contact location in head injury assessment and mitigation. Published by Elsevier Ltd.

Increasing attention has been given to the possible association of cervical spine (c-spine) injuries with abusive head trauma (AHT). The aims of this study were to describe c-spine MRI findings in hospitalized AHT patients. This is a retrospective study of children under the age of 5 years with AHT admitted to hospital in 2004-2013. Those with c-spine MRI were identified, and the images were reviewed. 250 AHT cases were identified, with 34 (14%) undergoing c-spine MRI. Eleven patients (32%) had 25 findings, including hematoma in 2, occiput-C1-C2 edema in 3, prevertebral edema in 6, facet edema in 2, and interspinous and/or muscular edema in 10. No patients had a clinically evident c-spine injury, a clinically unstable c-spine, or required c-spine surgery. C-spine MRI may identify abnormalities not apparent upon physical examination and the procedure should therefore be considered in cases of suspected AHT. © 2017 S. Karger AG, Basel.

Objective Chronic subdural hematoma (CSDH) is relatively common in neurosurgical field. However not all patients develop CSDH after minor head trauma. In this study, we evaluate the risk factors of post-traumatic CSDH. Methods Two-hundred and seventy-seven patients were enrolled and analyzed in this study from January 2012 to December 2013. Of those, 20 participants had minor head trauma developed CSDH afterward. We also included 257 patients with minor head trauma who did not develop CSDH during the same follow-up period as the control group. We investigated the risk factors related to the development of CSDH after minor head trauma. Results Old age (p=0.014), preexisting diabetes mellitus (p=0.010), hypertension (p=0.026), history of cerebral infarction (p=0.035), antiplatelet agents (p=0.000), acute subdural hematoma in the convexity (p=0.000), encephalomalacia (p=0.029), and long distance between skull and brain parenchyma (p=0.000) were significantly correlated with the development of CSDH after trauma. Multivariate analysis revealed that only the maximum distance between the skull and the cerebral parenchyma was the independent risk factor for the occurrence of CSDH (hazard ratio 2.55, p=0.000). Conclusion We should consider the possibility of developing CSDH in the post-traumatic patients with the identified risk factors. PMID:27169043

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.

Beta-adrenoreceptor blocker (beta-blocker) therapy may improve outcomes in surgical patients by decreasing cardiac oxygen consumption and hypermetabolism. Because beta-blockers can lower the systemic blood pressure and cerebral perfusion pressure, there is concern regarding their use in patients with head injury. However, beta-blockers may protect beta-receptor rich brain cells by attenuating cerebral oxygen consumption and metabolism. We hypothesized that beta-blockers are safe in trauma patients, even if they have suffered a significant head injury. Using pharmacy and trauma registry data of a Level I trauma center, we identified a cohort of trauma patients who received beta-blockers during their hospital stay (beta-cohort). Trauma admissions who did not receive beta-blockers were in the control cohort. beta-blocker status, in combination with other variables associated with mortality, were placed in a stepwise multivariate logistic regression to identify independent predictors of fatal outcome. In all, 303 (7%) of 4,117 trauma patients received beta-blockers. In the beta-cohort, 45% of patients were on beta-blockers preinjury. The most common reason to initiate beta-blocker therapy was blood pressure (60%) and heart rate (20%) control. The overall mortality rate was 5.6% and head injury was considered to be the major cause of death. After adjusting for age, Injury Severity Scale score, blood pressure, Glasgow Coma Scale score, respiratory status, and mechanism of injury, the odds ratio for fatal outcome was 0.3 (p < 0.001) for beta-cohort as compared with control. Decreased risk of fatal outcome was more pronounced in patients with a significant head injury. beta-blocker therapy is safe and may be beneficial in selected trauma patients with or without head injury. Further studies looking at beta-blocker therapy in trauma patients and their effect on cerebral metabolism are warranted.

OBJECTIVE Repetitive subconcussive head trauma is a consequence of participation in contact sports and may be linked to neurodegenerative diseases. The degree of neurological injury caused by subconcussive head trauma is not easily detectible, and this injury does not induce readily identifiable clinical signs or symptoms. Recent advancements in immunoassays make possible the detection and quantification of blood biomarkers linked to head trauma. Identification of a blood biomarker that can identify the extent of neurological injury associated with subconcussive head trauma may provide an objective measure for informed decisions concerning cumulative exposure to subconcussive head trauma. The purpose of the current study was to examine changes in the blood biomarkers of subconcussive head trauma over the course of an American football season. METHODS Thirty-five National Collegiate Athletic Association (NCAA) American football athletes underwent blood sampling throughout the course of a football season. Serial samples were obtained throughout the 2016 season, during which the number and magnitude of head impacts changed. Blood samples were analyzed for plasma concentrations of tau and serum concentrations of neurofilament light polypeptide (NF-L). Athletes were grouped based on their starter status, because athletes identified as starters are known to sustain a greater number of impacts. Between-group differences and time-course differences were assessed. RESULTS In nonstarters, plasma concentrations of tau decreased over the course of the season, with lower values observed in starters; this resulted in a lower area under the curve (AUC) (starters: 416.78 ± 129.17 pg/ml/day; nonstarters: 520.84 ± 163.19 pg/ml/day; p = 0.050). Plasma concentrations of tau could not be used to discern between starters and nonstarters. In contrast, serum concentrations of NF-L increased throughout the season as head impacts accumulated, specifically in those athletes categorized as starters. The higher serum concentrations of NF-L observed in starters resulted in a larger AUC (starters: 1605.03 ± 655.09 pg/ml/day; nonstarters: 1067.29 ± 272.33 pg/ml/day; p = 0.007). The AUC of the receiver operating characteristic curve analyses displayed fair to modest accuracy to identify athletes who were starters with the use of serum NF-L following periods of repetitive impacts. CONCLUSIONS The different patterns observed in serum NF-L and plasma tau concentrations provide preliminary evidence for the use of blood biomarkers to detect the neurological injury associated with repetitive subconcussive head trauma. Although further investigation is necessary, such findings might lay the foundation for the further development of an objective measure for the detection of neurological injury caused by subconcussive head trauma.

Isolated brain stem edema in a pediatric patient with head trauma: a case report.

Brain stem is the most vital part of our body and is a transitional region of the brain that connects the cerebrum with the spinal cord. Though, being small in size, it is full of indispensible functions such as the breathing, heart beat. Injury to the brain stem has similar effects as a brain injury, but it is more fatal. Use of the Glasgow Coma Score as a prognostic indicator of outcome in patients with head injuries is widely accepted in clinical practice. Traumatic brain stem edema in children is rare, but is associated with poor outcome. The question is that whether it is being aware of computerized tomography appearance of the posterior fossa when initial evaluating pediatric patients with head trauma at emergency clinics. Normal and edematous brain stem without an additional pathology are slightly different and not distinguished easily. On the other hand, brain stem edema should be promptly identified and appropriately treated in a short time.

Individuals who seek asylum are frequently fleeing violent persecution and may experience head injury (HI). However, little is known about the prevalence of HI in asylum seekers and refugees (ASR) despite the potential for HI to significantly affect cognitive and emotional functioning and to compromise asylum outcomes. This preliminary study investigates the prevalence of HI in ASR referred to a complex psychological trauma service. Participants were 115 adult ASR referred to a community psychological trauma service with moderate to severe mental health problems associated with psychological trauma. They were screened for a history of HI using a questionnaire developed for the study. Interpreters were used when required. The overall prevalence of HI was 51%. At least 38% of those with HI had a moderate-severe HI that could cause persisting disability. In 53% of those with HI, the cause was torture, human trafficking or domestic violence. Repeat HI can have cumulative effects on function; it was common, and was reported in 68% of those with HI. An injury to the head was not known to mental health clinicians prior to screening in 64% of cases. The emotional and cognitive consequences of HI in ASR may increase the vulnerability of this disadvantaged group, and can be associated with neurobehavioural problems affecting daily life and may compromise asylum outcomes. Routine screening for HI in ASR is needed, as are links to neuropsychology and brain injury services for advice, assessment and intervention.

Traumatic brain injury (TBI) constitutes the leading cause of posttraumatic mortality. Practically, the major interventions required to treat TBI predicate expedited transfer to CT after excluding other immediately life-threatening conditions. At our center, trauma responses variably consist of either full trauma activation (FTA) including an attending trauma surgeon or a non-trauma team response (NTTR). We sought to explore whether FTAs expedited the time to CT head (TTCTH). Retrospective review of augmented demographics of 88 serious head injuries identified from a Regional Trauma Registry within one year at a level I trauma center. The inclusion criteria consisted of a diagnosis of head injury recorded as intubated or GCS < 13; and CT-head scanning after arriving the emergency department. Data was analyzed using STATA. There were 58 FTAs and 30 NTTRs; 86% of FTAs and 17% of NTTRs were intubated prehospital out of 101 charts reviewed in detail; 13 were excluded due to missing data. Although FTAs were more seriously injured (median ISS 29, MAIS head 19, GCS score at scene 6.0), NTTRs were also severely injured (median ISS 25, MAIS head 21, GCS at scene 10) and older (median 54 vs. 26 years). Median TTCTH was double without dedicated FTA (median 50 vs. 26 minutes, p < 0.001), despite similar justifiable delays (53% NTTR, 52% FTA). Without FTA, most delays (69%) were for emergency intubation. TTCTH after securing the airway was longer for NTTR group (median 38 vs. 26 minutes, p =0.0013). Even with no requirements for ED interventions, TTCTH for FTA was less than half versus NTTR (25 vs. 61 minutes, p =0.0013). Multivariate regression analysis indicated age and FTA with an attending surgeon as significant predictors of TTCTH, although the majority of variability in TTCTH was not explained by these two variables (R² = 0.33). Full trauma activations involving attending trauma surgeons were quicker at transferring serious head injury patients to CT. Patients with FTA were younger and more seriously injured. Discerning the reasons for delays to CT should be used to refine protocols aimed at minimizing unnecessary delays and enhancing workforce efficiency and clinical outcome.

We evaluated personality change following head injury in 68 patients at 6 months postinjury using the NEO Five-Factor Inventory to assess the five personality dimensions of the Five-Factor Model of Personality. All items had to be rated twice, once for the preinjury and once for the current status. Twenty-eight trauma patients with injuries to other parts of the body than the head were used as controls. For the head-injured group, 63 relatives also completed the questionnaire. The results showed no differences between the ratings of head-injured patients and the ratings of trauma control patients. Both groups showed significant change in the personality dimensions Neuroticism, Extraversion, and Conscientiousness. Compared to their relatives, head-injured patients report a smaller change in Extraversion and Conscientiousness. Changes were not reported on the Openness and Agreeableness scales, by neither the head-injured or their relatives, nor by the trauma controls.

To assess the risk and prognostic factors of ventilator-associated pneumonia in trauma patients, with an emphasis on the inflammatory response. Case-control study. Trauma intensive care unit. Of 190 consecutive mechanically ventilated patients, those with microbiologically confirmed pneumonia (n = 62) were matched with 62 controls without pneumonia. None. Clinical, microbiological, and outcome variables were recorded. Cytokines were measured in serum and blind bronchoalveolar lavage specimens at onset of pneumonia. Multivariate analyses of risk and prognostic factors for ventilator-associated pneumonia were done. Increased severity of head and neck injury (odds ratio, 11.9; p < .001) was the only independent predictor of pneumonia. Among patients with pneumonia, serum levels of interleukin-6 (p = .019) and interleukin-8 (p = .036) at onset of pneumonia were higher in nonresponders to treatment. Moreover, serum levels of tumor necrosis factor-alpha (p = .028) and interleukin-6 (p = .007) at onset of pneumonia were higher in nonsurvivors. Mortality in the intensive care unit was 23% in cases and controls. Nonresponse to antimicrobial treatment (odds ratio, 22.2; p = .001) and the use of hyperventilation (p = .021) were independent predictors of mortality in the intensive care unit for patients with pneumonia. Severe head and neck trauma is strongly associated with ventilator-associated pneumonia. A higher inflammatory response is associated with nonresponse to treatment and mortality among patients with pneumonia. Although pneumonia did not influence mortality, nonresponse to treatment independently predicted mortality among these patients.

Citywide trauma experience in Mwanza, Tanzania: a need for urgent intervention

Background Trauma remains a leading cause of morbidity and mortality in resource limited countries. There is paucity of published reports on trauma care in Tanzania, particularly the study area. This study was carried out to describe our experiences in trauma management outlining the etiological spectrum, injury characteristics and treatment outcome of trauma patients at our local setting and compare our results with those from other centers in the world. Methods A descriptive prospective study of trauma patients was conducted at Bugando Medical Centre from April 2010 to March 2012. Statistical data analysis was done using SPSS software version 17.0. Results A total of 5672 trauma patients were enrolled in the study. The male to female ratio was 2.3: 1. The majority of patients were in the 2nd decade of life. Road traffic accident was the most common cause of trauma accounting for 60.7% of cases. The majority of patients (76.6%) sustained blunt injuries. Musculoskeletal (68.5%) and head/neck (52.6%) were the most frequent body region injured. Soft tissue injuries (open wounds) and fractures were the most common injuries accounting for 82.8% and 76.8% respectively. Majority of patients (74.4%) were treated surgically with wound debridement (94.0%) being the most frequently performed procedure. Postoperative complications were recorded in 31.5% of cases. The overall median duration of hospitalization was 26 days (range 1 day to 144 days). Mortality rate was 16.7%. Patients who had polytrauma, burn injuries and those who had tetanus and long bone fractures stayed longer in the hospital and this was statistically significant (P < 0.001), whereas the age > 65 years, severe trauma, admission Systolic Blood Pressure < 90 mmHg, presence of tetanus, severe head injury, the duration of loss of consciousness, the need for intensive care unit admission and finding of space occupying lesion on CT scan of the brain significantly influenced mortality (P < 0.001). Conclusion Trauma resulting from road traffic accidents remains a major public health problem in this part of Tanzania. Urgent preventive measures targeting at reducing the occurrence of road traffic accidents is necessary to reduce the incidence of trauma in this region. PMID:24499566

The objective of the study was to determine whether fear of malpractice is associated with emergency physicians' decision to order head computed tomography (CT) in 3 age-specific scenarios of pediatric minor head trauma. We hypothesized that physicians with higher fear of malpractice scores will be more likely to order head CT scans. Board-eligible/board-certified members of the Michigan College of Emergency Physicians were sent a 2-part survey consisting of case scenarios and demographic questions. Effect of fear of malpractice on the decision to order a CT scan was evaluated using a cumulative logit model. Two hundred forty-six members (36.5%) completed the surveys. In scenario 1 (infant), being a male and working in a university setting were associated with reduced odds of ordering a CT scan (odds ratio [OR], 0.40; 95% confidence interval [CI], 0.18-0.88; and OR, 0.35; 95% CI, 0.13-0.96, respectively). In scenario 2 (toddler), working for 15 years or more, at multiple hospitals, and for a private group were associated with reduced odds of ordering a CT scan (OR, 0.46; 95% CI, 0.26-0.79; OR, 0.36; 95% CI, 0.16-0.80; and OR, 0.51; 95% CI, 0.27-0.94, respectively). No demographic variables were significantly associated with ordering a CT scan in scenario 3 (teen). Overall, the fear of malpractice was not significantly associated with ordering a CT scan (OR, 1.28; 95% CI, 0.73-2.26; and OR, 1.70; 95% CI, 0.97-3.0). Only in scenario 2 was high fear significantly associated with increased odds of ordering a CT scan (OR, 2.09; 95% CI, 1.08-4.05). Members of Michigan College of Emergency Physicians with a higher fear of malpractice score tended to order more head CT scans in pediatric minor head trauma. However, this trend was shown to be statistically significant only in 1 case and not overall.

Although they are less severe than a full blown concussive episodes, subconcussive impacts happen much more frequently and current research has suggested this form of head trauma may have an accumulative effect and lead to neurological impairment later in life. To investigate the acute effects that subconcussive head trauma may have on the default mode network of the brain resting-state, functional magnetic resonance was performed. Twenty-four current collegiate rugby players were recruited and all subjects underwent initial scanning 24 h prior to a scheduled full contact game to provide a baseline. Follow-up scanning of the rugby players occurred within 24 h following that game to assess acute effects from subconcussive head trauma. Differences between pre-game and post-game scans showed both increased connectivity from the left supramarginal gyrus to bilateral orbitofrontal cortex and decreased connectivity from the retrosplenial cortex and dorsal posterior cingulate cortex. To assess whether or not a history of previous concussion may lead to a differential response following subconcussive impacts, subjects were further divided into two subgroups based upon history of previous concussion. Individuals with a prior history of concussion exhibited only decreased functional connectivity following exposure to subconcussive head trauma, while those with no history showed increased connectivity. Even acute exposure to subconcussive head trauma demonstrates the ability to alter functional connectivity and there is possible evidence of a differential response in the brain for those with and without a history of concussion.

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.

SUMMARY Epidemiological observations suggest that exposures in youth may trigger narcolepsy in genetically predisposed individuals. In this population-based case–control study, we sought to identify all prevalent cases of narcolepsy with cataplexy aged 18–50 years as of 1 July 2001, in King County, Washington. The 45 eligible cases who were DQB1*0602-positive were compared with 95 controls with this allele, identified through random-digit dialing and buccal smears. Cases and controls were interviewed in person about physician-diagnosed infectious and non-infectious illnesses, immunizations, head trauma and parasomnias or psychiatric problems during youth. Narcolepsy with cataplexy was more frequent in African-Americans and in poorer households. Adjusting for these factors, the condition was 5.4-fold more common [95% confidence interval (CI) = 1.5–19.1] among people reporting a physician-diagnosed strep throat before the age of 21 years. No other significant associations with childhood diseases, immunizations or head trauma were found. However, prevalence was increased 16.3-fold (95% CI = 6.1–44.1) in subjects who reported having had ‘night terrors’. Strep throat may be related to narcolepsy with cataplexy in genetically susceptible individuals. The association with night terrors could simply reflect early symptoms of narcolepsy, or they could be a prodromal sign of disturbed sleep physiology. keywords epidemiology, head injuries, immunization, narcolepsy, night terrors, streptococcal infections PMID:19732319

PurposeThis retrospective cohort study assesses the visual outcomes of patients who survive gunshot wounds to the head.MethodsThe Elmhurst City Hospital Trauma Registry and Mount Sinai Data Warehouse were queried for gun trauma resulting in ocular injury over a 16-year period. Thirty-one patients over 16 years of age were found who suffered a gunshot wound to the head and resultant ocular trauma: orbital fracture, ruptured globe, foreign body, or optic nerve injury. Gun types included all firearms and air guns. Nine patients were excluded due to incorrect coding or unavailable charts. Statistical analysis was performed using a simple bivariate analysis (χ 2 ).ResultsOf the 915 victims of gun trauma to the head, 27 (3.0%) sustained ocular injuries. Of the 22 patients whose records were accessible, 18 survived. Eight of the 18 surviving patients (44%) suffered long-term visual damage, defined as permanent loss of vision in at least one eye to the level of counting fingers or worse. Neither location of injury (P=0.243), nor type of gun used (P=0.296), nor cause of gun trauma (P=0.348) predicted visual loss outcome. The Glasgow Coma Scale eye response score on arrival to the hospital also did not predict visual loss outcome (P=0.793).ConclusionThere has been a dearth of research into gun trauma and even less research on the visual outcomes following gun trauma. Our study finds that survivors of gun trauma to the head suffer long-term visual damage 44% of the time after injury.

Objective: The clinical presentations of head trauma due to falls among young children aged less than 2 years are controversial, particularly in Japan, as the history of trauma recounted by a caretaker is not always reliable. The purpose of this study was to assess the validity of caregiver’s reports on head trauma due to falls in young children aged less than 2 years in Japan. Methods: All patients <2 years of age presenting with head trauma resulting from a fall who were admitted to 3 children’s hospitals in Japan from January 2001 to December 2005 were retrospectively reviewed (N = 58). The clinical presentations were compared among groups categorized by the heights from which the patient fell (short (≤120 cm) or long (>120 cm)) and the surface on which the patient landed (carpet, tatami (Japanese mattress), hardwood floor, or concrete). Results: Patients who suffered short falls were more likely to present with subdural hemorrhage (SDH) than those who suffered long falls (74% and 40%, respectively, P = 0.027). More specifically, 62% of short falls showed SDH indicative of shaken baby syndrome (e.g. multilayer SDH). Neurological symptoms, cyanosis, and SDH were more commonly observed in patients who landed on carpeted or tatami surfaces than in those who landed on hardwood or concrete floors. Conclusions: Short falls and landing on soft surfaces resulted in the presentation of severer clinical symptoms than did long falls and landing on hard surfaces, suggesting that the validity of caretakers’ reports on infant or young children’s head trauma due to falls is low. Further research is warranted to investigate the cause of infant head trauma due to falls. PMID:23761991

Among pediatric injury, brain injury is a leading cause of death and disability. To improve outcomes, many developed countries built neurotrauma databank (NTDB) system but there was not established nationwide coverage NTDB until 2009 and there have been few studies on pediatric traumatic head injury (THI) patients in Korea. Therefore, we analyzed epidemiology and outcome from the big data of pediatric THI. We collected data on pediatric patients from 23 university hospitals including 9 regional trauma centers from 2010 to 2014 and analyzed their clinical factors (sex, age, initial Glasgow coma scale, cause and mechanism of head injury, presence of surgery). Among all the 2617 THI patients, total number of pediatric patients was 256. The average age of the subjects was 9.07 (standard deviation±6.3) years old. The male-to female ratio was 1.87 to 1 and male dominance increases with age. The most common cause for trauma were falls and traffic accidents. Age ( p =0.007), surgery ( p <0.001), mechanism of trauma ( p =0.016), subdural hemorrhage (SDH) ( p <0.001), diffuse axonal injury (DAI) ( p <0.001) were statistically significant associated with severe brain injury. Falls were the most common cause of trauma, and age, surgery, mechanism of trauma, SDH, DAI increased with injury severity. There is a critical need for effective fall and traffic accidents prevention strategies for children, and we should give attention to these predicting factors for more effective care.

Non-accidental trauma (NAT) is a leading cause of childhood traumatic injury and death in the United States. It is estimated that 1,400 children died from maltreatment in the United States in 2002 and abusive head trauma (AHT) accounted for 80% of these deaths. This review examines the epidemiology and risk factors for NAT as well as the general presentation and required medical work up of abused children. In addition, potential algorithms for recognizing cases of abuse are reviewed as well as outcomes in children with NAT and potential neurosurgical interventions which may be required. Finally, the evidence for seizure prophylaxis in this population is addressed. PMID:26835337

Isolated nonoperative mild head injuries (INOMHI) occur with increasing frequency in an aging population. These patients often have multiple social, discharge, and rehabilitation issues, which far exceed the acute component of their care. This study was aimed to compare the outcomes of patients with INOMHI admitted to three services: trauma surgery, neurosurgery, and neurology. Retrospective case series (January 1, 2009 to August 31, 2013) at an academic Level I trauma center. According to an institutional protocol, INOMHI patients with Glasgow Coma Scale (GCS) of 13 to 15 were admitted on a weekly rotational basis to trauma surgery, neurosurgery, and neurology. The three populations were compared, and the primary outcomes were survival rate to discharge, neurological status at hospital discharge as measured by the Glasgow Outcome Score (GOS), and discharge disposition. Four hundred eighty-eight INOMHI patients were admitted (trauma surgery, 172; neurosurgery, 131; neurology, 185). The mean age of the study population was 65.3 years, and 58.8% of patients were male. Seventy-seven percent of patients has a GCS score of 15. Age, sex, mechanism of injury, Charlson Comorbidity Index, Injury Severity Score, Abbreviated Injury Scale in head and neck, and GCS were similar among the three groups. Patients who were admitted to trauma surgery, neurosurgery and neurology services had similar proportions of survivors (98.8% vs 95.7% vs 94.7%), and discharge disposition (home, 57.0% vs 61.6% vs 55.7%). The proportion of patients with GOS of 4 or 5 on discharge was slightly higher among patients admitted to trauma (97.7% vs 93.0% vs 92.4%). In a logistic regression model adjusting for Charlson Comorbidity Index CCI and Abbreviated Injury Scale head and neck scores, patients who were admitted to neurology or neurosurgery had significantly lower odds being discharged with GOS 4 or 5. While the trauma group had the lowest proportion of repeats of brain computed tomography (61.6%), the neurosurgery group had the highest proportion of intensive care unit admission (29.8%), and the neurology group had the longest emergency department stay (7.5 hours), there were no significant differences in duration of hospital stay, in-hospital complications, and readmission within 30 days. Although there were differences in use of health care resources, and the proportion of patients with GOS of 4 or 5 on discharge was slightly higher among patients admitted to trauma, most clinical outcomes were similar in INOMHI patients admitted to trauma surgery, neurosurgery, or neurology in our institution. A rotational policy of admitting INOMHI patients is feasible among services with expertise in and commitment to the care of these patients. Therapeutic/care management study, level IV.

In this study, we present our 11-year experience in the management and clinical outcome of 888 chest trauma cases as a result of blunt and penetrating injuries in our university hospital in Damascus, Syria. Methods We reviewed files of 888 consequent cases of chest trauma between January 2000 and January 2011. The mean age of our patients was 31 ± 17 years mostly males with blunt injuries. Patients were evaluated and compared according to age, gender, etiology of trauma, thoracic and extra-thoracic injuries, complications, and mortality. Results The leading cause of the trauma was violence (41%) followed by traffic accidents (33%). Pneumothorax (51%), Hemothorax (38%), rib fractures (34%), and lung contusion (15%) were the most common types of injury. Associated injuries were documented in 36% of patients (extremities 19%, abdomen 13%, head 8%). A minority of the patients required thoracotomy (5.7%), and tube thoracostomy (56%) was sufficient to manage the majority of cases. Mean hospital LOS was 4.5 ± 4.6 days. The overall mortoality rate was 1.8%, and morbidity (n = 78, 8.7%). Conclusions New traffic laws (including seat belt enforcement) reduced incidence and severity of chest trauma in Syria. Violence was the most common cause of chest trauma rather than road traffic accidents in this series, this necessitates epidemiologic or multi-institutional studies to know to which degree violence contributes to chest trauma in Syria. The number of fractured ribs can be used as simple indicator of the severity of trauma. And we believe that significant neurotrauma, traffic accidents, hemodynamic status and GCS upon arrival, ICU admission, ventilator use, and complication of therapy are predictors of dismal prognosis.

Squamous cell carcinoma presenting with trigeminal anesthesia: An uncommon presentation of head & neck cancer with unknown primary.

PubMed

Shah, Ameer T; Dagher, Walid I; O'Leary, Miriam A; Wein, Richard O

The differential diagnosis of facial anesthesia is vast. This may be secondary to trauma, neoplasm, both intracranial and extracranial, infection, and neurologic disease. When evaluating a patient with isolated facial anesthesia, the head and neck surgeon often thinks of adenoid cystic carcinoma, which has a propensity for perineural invasion and spread. When one thinks of head and neck squamous cell carcinoma with or without unknown primary, the typical presentation involves dysphagia, odynophagia, weight loss, hoarseness, or more commonly, a neck mass. Squamous cell carcinoma presenting as facial anesthesia and perineural spread, with no primary site is quite rare. Case presentations and review of the literature. Trigeminal anesthesia is an uncommon presentation of head and neck squamous cell carcinoma with unknown primary. We present two interesting cases of invasive squamous cell carcinoma of the trigeminal nerve, with no primary site identified. We will also review the literature of head and neck malignancies with perineural spread and the management techniques for the two different cases presented. Copyright © 2016 Elsevier Inc.

Within the context of medical examiner's offices, forensic anthropologists are increasingly being asked to assist with the interpretation of traumatic skeletal injury. This case study presents an example of trauma analysis performed by forensic anthropologists at the Maricopa County Forensic Science Center in Phoenix, Arizona. The primary goal of this study is to document an uncommon pattern of traumatic injury-severe grinding abrasions of the lower appendage that macroscopically resemble sharp force trauma, especially as observed in dismemberment cases-resulting from an individual being dragged beneath a Light Rail train for c. 1.7 miles. The abraded skeletal elements include a femoral shaft fragment, a femoral head portion, and the right foot. Second, this study aims to illustrate the efficacy of forensic anthropological analysis of patterned skeletal trauma. Finally, this study demonstrates the critical importance of analyzing scene information before drawing conclusions as to the etiology of a traumatic injury pattern. © 2015 American Academy of Forensic Sciences.

Geriatric trauma.

PubMed

Adams, Sasha D; Holcomb, John B

2015-12-01

The landscape of trauma is changing due to an aging population. Geriatric patients represent an increasing number and proportion of trauma admissions and deaths. This review explores recent literature on geriatric trauma, including triage criteria, assessment of frailty, fall-related injury, treatment of head injury complicated by coagulopathy, goals of care, and the need for ongoing education of all surgeons in the care of the elderly. Early identification of high-risk geriatric patients is imperative to initiate early resuscitative efforts. Geriatric patients are typically undertriaged because of their baseline frailty being underappreciated; however, centers that see more geriatric patients do better. Rapid reversal of anticoagulation is important in preventing progression of brain injury. Anticipation of difficult disposition necessitates early involvement of physical therapy for rehabilitation and case management for appropriate placement. Optimal care of geriatric trauma patients will be based on the well established tenets of trauma resuscitation and injury repair, but with distinct elements that address the physiological and anatomical challenges presented by geriatric patients.

Post-concussion syndrome is a well-described complication following moderate and severe head trauma but whether it occurs after mild head injury in children remains unclear. The aim of this study was to evaluate whether exposure to mild head injury with potential additional risk factors (non-surgical lesion on computed tomographic, high kinetic trauma, or Glasgow Coma Scale <15) is associated with attention deficit hyperactivity disorder (ADHD) after the head trauma. This study was performed in an emergency department on children admitted between 2009 and 2013. It compared victims of mild head injury aged 6-16 years with matched children presenting isolated non-surgical forearm fracture (ratio1/2). ADHD was assessed using Conners' Global Index-Parent short version 3-40 months after the trauma. The patients were compared using chi-square test or Fisher's exact test, t test or u-test as appropriate with a p value set at 0.05. During the study period, 676 patients were admitted for mild head injury. Among them, 34 (5 %) fulfilled the inclusion criteria and were compared with 64 matched patients admitted for a forearm fracture. The groups were comparable. ADHD was observed in both groups (18 % in the mild head injury group, 11 % in the control group) with no significant differences between groups. The prevalence was high when compared to an expected frequency of 3.5-5.6 % in children aged 6-12 years in the general population. These results suggest that pre-existing ADHD may have contributed to injury proneness in both groups and does not argue for a specific risk of ADHD induced by mild head injury. The diagnosis of ADHD should be evoked at admission of children aged 6-16 years presenting with a trauma.

Acromegaly resolution after traumatic brain injury: a case report.

Cob, Alejandro

Anterior hypopituitarism is a common complication of head trauma, with a prevalence of 30% to 70% among long-term survivors. This is a much higher frequency than previously thought and suggests that most cases of post-traumatic hypopituitarism remain undiagnosed and untreated. Symptoms of hypopituitarism are very unspecific and very similar to those in traumatic brain injury patients in general, which makes hypopituitarism difficult to diagnose. The factors that predict the likelihood of developing hypopituitarism following traumatic brain injury remain poorly understood. The incidence of a specific hormone deficiency is variable, with growth hormone deficiency reported in 18% to 23% of cases. A 23-year-old Hispanic man with a 2-year history of hypertension and diabetes presented with severe closed-head trauma producing diffuse axonal injury, subarachnoid hemorrhage and a brain concussion. A computed tomography scan showed a pituitary macroadenoma. The patient has clinical features of acromegaly and gigantism without other pituitary hyperfunctional manifestations or mass effect syndrome. A short-term post-traumatic laboratory test showed high levels of insulin like growth factor 1 and growth hormone, which are compatible with a growth hormone-producing pituitary tumor. At the third month post-trauma, the patient's levels of insulin like growth factor 1 had decreased to low normal levels, with basal low levels of growth hormone. A glucose tolerance test completely suppressed the growth hormone, which confirmed resolution of acromegaly. An insulin tolerance test showed lack of stimulation of growth hormone and cortisol, demonstrating hypopituitarism of both axes. Even though hypopituitarism is a frequent complication of traumatic brain injury, there are no reports in the literature, to the best of my knowledge, of patients with hyperfunctional pituitary adenomas, such as growth hormone-producing adenoma, that resolved after head trauma. A clear protocol has not yet been established to identify which patients should be screened for hypopituitarism. Predictive factors that might determine the likelihood of developing post-traumatic hypopituitarism have not been clearly established, but there is no evidence of the presence of pituitary adenomas as a risk factor in otherwise healthy patients.

Severe head injuries often lead to serious medical and socioeconomic sequelae. The incidence rate indicated in other studies shows a wide variation due to differences in selection criteria. Based upon an unselected population, the incidence of severe head injury was calculated and the surviving patients were interviewed and clinically examined 3 years after the accident in order to describe the course, rehabilitation and psychosocial sequelae after severe head injury. Retrospectively we collected 80 patients living in the canton of St. Gallen who had a severe head injury requiring hospitalization in 1987, indicating an incidence of 20 per 100,000 inhabitants. 22 (28%) of these patients died as a consequence of the head trauma. The best predictor was the Glasgow coma score at admission, which showed a highly significant direct correlation with survival rate. Regarding the degree of impairment of survivors the duration of posttraumatic amnesia was the best predictive parameter. Of the 45 patients controlled 3 years after the head trauma only 11% were severely impaired in daily activities. 79% of the patients who were gainfully employed before the accident were working full- or at least part-time. However, only 3 patients (7%) were absolutely free of symptoms. Most patients suffered from cognitive and emotional deficits. Based on an estimated incidence for minor head trauma of 174 per 100,000 inhabitants, a total annual incidence for all head traumas of 194 per 100,000 inhabitants is calculated, with severe head injury representing about 1/9 of all head injuries.

2009-01-01

Background Blunt diaphragmatic rupture (BDR) is a rare event and represents a diagnostic challenge. The purpose of our study was to review our experience with BDR at the Sunnybrook Health Sciences Centre (Sunnybrook), the largest trauma centre in Canada, and to highlight recent changes in the diagnosis and management of the condition. Methods We retrospectively reviewed the cases of patients with BDR who were admitted to Sunnybrook between January 1986 and December 2003 using our trauma registry. We performed Student t and Fisher exact tests to compare our findings on patients with BDR with those on the entire cohort of blunt trauma patients admitted to our centre. Results Most patients with BDR were men (64.4%) with a mean age of 42 years. Left-sided tears were most common (65.0%). Patients with BDR had a very high Injury Severity Score (38) and very high mortality (28.8%). Of those who were injured as a result of motor vehicle collisions (MVCs), a significantly greater percentage of patients in the BDR group than in the entire cohort of blunt trauma patients were drivers or front-seat passengers. Patients with BDR were also significantly less likely to be pedestrians, to have experienced a fall or to be involved in a motorcycle collision. Patients with BDR had a higher chest, abdomen, pelvis and extremity Abbreviated Injury Scale score than all blunt trauma patients in general. Most of our patients underwent laparotomy (93.3%). The most common causes of death among patients with BDR were head injury (25.0%), intra-abdominal bleeding (23.3%) and pelvic hemorrhage (18.3%). Conclusion Blunt diaphragmatic rupture is rare and difficult to diagnose; however, certain MVC characteristics along with severe associated injuries should raise the index of suspicion. These associated injuries include injuries to the head, chest (including the aorta), abdomen and pelvis. Computed tomographic angiography is essential to rule out associated aortic injury and to increase the diagnostic accuracy of BDR. PMID:19503660

High risk of hypogonadism after traumatic brain injury: clinical implications.

PubMed

Agha, Amar; Thompson, Christopher J

2005-01-01

Several recent studies have convincingly documented a close association between traumatic brain injury (TBI) and pituitary dysfunction. Post-traumatic hypogonadism is very common in the acute post-TBI phase, though most cases recover within six to twelve months following trauma. The functional significance of early hypogonadism, which may reflect adaptation to acute illness, is not known. Hypogonadism persists, however, in 10-17% of long-term survivors. Sex steroid deficiency has implications beyond psychosexual function and fertility for survivors of TBI. Muscle weakness may impair functional recovery from trauma and osteoporosis may be exacerbated by immobility secondary to trauma. Identification and appropriate and timely management of post-traumatic hypogonadism is important in order to optimise patient recovery from head trauma, improve quality of life and avoid the long-term adverse consequences of untreated sex steroid deficiency.

The management of gunshot wounds is a rare challenge for trauma surgeons in Germany and Central Europe as a result of the low incidence of this type of trauma. Penetrating injuries occur with an incidence of 5% in Germany. They are caused by gunshots or more commonly by knives or other objects, for example during accidents. Since even the number of patients who are treated at level 1 trauma centres is limited by the low incidence, the objective of this study was to assess the epidemiology and outcome of gunshot and stab wounds in Germany. Since 2009, the trauma registry of the German Trauma Society (TraumaRegister DGU®) has been used to assess not only whether a trauma was penetrating but also whether it was caused by a gunshot or a stabbing. On the basis of this registry, we identified relevant cases and defined the observation period. Data were taken from the standard documentation forms that participating German hospitals completed between 2009 and 2011. We did not specify exclusion criteria in order to obtain as comprehensive a picture as possible of the trauma entities investigated in this study. As a result of the high incidence of gunshot wounds to the head and the implications of this type of injury for the entire group, a subgroup of patients without head injuries was analysed. From 2009 to 2011, there were 305 patients with gunshot wounds and 871 patients with stab wounds. The high proportion of suicide-related gunshot wounds to the head resulted in a cumulative mortality rate of 39.7%. Stab wounds were associated with a lower mortality rate (6.2%). Every fourth patient with a gunshot or stab wound presented with haemorrhagic shock, which was considerably more frequently seen during the prehospital phase than during the inhospital phase of patient management. Of the patients with gunshot wounds, 26.9% required transfusions. This percentage was three times higher than that for patients with blunt trauma. In Germany, gunshot and stab wounds have a low incidence and are mostly caused by violent crime or attempted suicide. Depending on the site of injury, they have a high mortality and are often associated with major haemorrhage. As a result of the low incidence of these types of trauma, further data and analyses are required which can provide the basis for an evaluation of the long-term quality of the management of patients with stab or gunshot wounds.

This study presents results from an intervention designed to improve identification and response to abusive head trauma in a tertiary paediatric hospital in Vietnam. One hundred and sixteen healthcare professionals (paediatric medical and nursing staff) completed a clinical training programme and participated in its evaluation. A pre-post-test and follow-up design was used to evaluate the outcomes. Questionnaires were used to collect data prior to training, at six weeks and at six months. Generalised linear modelling was used to examine changes in diagnostic skills and knowledge of the consequences of shaken baby syndrome (SBS) (a form of abusive head trauma), its prevention and treatment. At baseline, awareness and knowledge reflected no former abusive head trauma training. Following the intervention, participants had an increased awareness of shaken baby syndrome and the potential consequences of shaking infants and had acquired techniques to inform parents how to manage the crying infant. The intervention was effective in raising awareness of shaken baby syndrome and its consequences amongst the participating healthcare professionals in Vietnam. Training can improve detection and prevention of abusive head trauma, and the intervention has the potential to be adapted for similar settings internationally. ©2017 Foundation Acta Paediatrica.

Pseudoaneurysm and fistula formation are well-documented complications of arterial vascular injury and may be associated with significant morbidity and mortality. The purpose of this manuscript is to review the presentation and therapy of patients with traumatic vascular injuries of the head and neck. Eight patients were admitted to a Level 1 Trauma Center and diagnostic angiography of the carotid artery and vertebral circulation was performed. The mechanisms of injury included motor vehicle accident, gunshot wound,stab wound and aggravated assault. Cause of trauma, vascular lesion,endovascular therapy and outcome were analyzed retrospectively. The angiographic findings, clinical presentation and hospital course were reviewed.more » There were eight patients, seven males and one female, aged 17-65. Four patients (50%) had multiple lesions; four had pseudoaneurysms, two with fistula formation and two with active arterial hemorrhage. A total of 17 lesions were embolized using coils,Polyvinyl Alcohol (PVA), Gelfoam or a combination. Two of the 17 lesions received stents. Six of the eight patients remained clinically improved or stable at varying follow-up intervals. One of the four patients who presented with penetrating trauma and neurological deficits had resolution of right hemiplegia at the 8{sup th}month follow-up. One of the four patients who sustained blunt trauma and carotid-cavernous fistula presented with a new pseudoaneurysm at the 2-month post-embolization follow-up. The evolution of diagnostics neuroangiogaphic techniques provides opportunities for endovascular therapy of traumatic vascular lesions of the head and neck that are minimally invasive, attractive options in selected cases.« less

Off-road motorcycling is a very popular sport practiced by countless people worldwide. Despite its popularity, not much has been published on the severity and distribution of central nervous system-related injuries associated with this activity in the pediatric population. The purpose of this study was to confirm, characterize, and document the rate of head and spine injuries associated with off-road motorcycling in this population. All patients aged 18 years or less who were treated for a motorbike injury at the authors' institution (a Level 1 regional trauma center) between 2000 and 2007 were identified through in-house surgical and trauma registries. Type, mechanism, and severity of CNS-related injuries were assessed, including: incidence of traumatic brain injury (TBI), loss of consciousness (LOC), Glasgow Coma Scale (GCS) score, head CT findings, neurological deficits, spinal fractures, cervical strain, and use of protective gear, including helmets. During the 8-year period of study, 298 accidents were evaluated in 248 patients. The patients' mean age at the time of injury was 14.2 ± 2.7 years. Head injury or TBI was identified in 60 (20.1%) of 298 cases (involving 58 of 248 patients). Fifty-seven cases were associated with LOC, and abnormalities were identified on head CT in 10 patients; these abnormalities included skull fractures and epidural, subdural, subarachnoid, and intraparenchymal hemorrhages. The GCS score was abnormal in 11 cases and ranged from 3 to 15, with an overall mean of 14.5. No patients required cranial surgery. Helmet use was confirmed in 43 (71.6%) of the cases involving TBI. Spine fractures were identified in 13 patients (4.3%) and 5 required surgical fixation for their injury. The authors found a high occurrence of head injuries following pediatric off-road motorcycle riding or motocross accidents despite the use of helmets. Additionally, this study severely underestimates the rate of mild TBIs in this patient population. Our data indicate that motocross is a high-risk sport despite the use of protective gear. Riders and parents should be counseled accordingly about the risks prior to participation.

Abusive Head Trauma (AHT) refers to the combination of findings formerly described as shaken baby syndrome. Although these findings can be caused by shaking, it has become clear that in many cases there may have been impact trauma as well. Therefore a less specific term has been adopted by the American Academy of Pediatrics. AHT is a relatively common cause of childhood neurotrauma with an estimated incidence of 14-40 cases per 100,000 children under the age of 1 year. About 15-23% of these children die within hours or days after the incident. Studies among AHT survivors demonstrate that approximately one-third of the children are severely disabled, one-third of them are moderately disabled and one-third have no or only mild symptoms. Other publications suggest that neurological problems can occur after a symptom-free interval and that half of these children have IQs below the 10th percentile. Clinical findings are depending on the definitions used, but AHT should be considered in all children with neurological signs and symptoms especially if no or only mild trauma is described. Subdural haematomas are the most reported finding. The only feature that has been identified discriminating AHT from accidental injury is apnoea. AHT should be approached with a structured approach, as in any other (potentially lethal) disease. The clinician can only establish this diagnosis if he/she has knowledge of the signs and symptoms of AHT, risk factors, the differential diagnosis and which additional investigations to perform, the more so since parents seldom will describe the true state of affairs spontaneously.

Trauma during pregnancy is among leading causes of non-pregnancy-related maternal death (MD). This study describes risk factors for MD from trauma during pregnancy in a large urban population. We queried an urban Level One Trauma Center registry for the medical records of pregnant women suffering trauma from 1990 to 2007. Associations were examined between maternal demographics, injury mode details, injury characteristics, and risk of maternal death upon arrival to the emergency room. Overall, 351 patients were identified. Most traumas was caused by motor vehicle collision (71.8 %), accounting for 78.9 % of MD, followed by gun shot wound (10.3 %), stabbing (8.5 %), falls (4.3 %), and assaults (4 %). Abdominal and head injuries were more frequent in cases of MD compared with patients admitted to the hospital (33.3 vs. 25.1 % abdominal, 55.6 vs. 29.4 % head; p < 0.001). A greater proportion of MDs were characterized by lack of restraint use (66.7 %) compared to women admitted to the hospital (47.7 %) and women discharged after observation (43.1 %); p = 0.014. ER deaths had more negative base excess scores than women who were admitted or discharged (-14 vs. -3 vs. -2; p < 0.001), lower blood pH values (6.96 vs. 7.40 vs. 7.44; p < 0.001), greater Injury Severity Scores (ISS) (44.4 vs. 11.49 vs. 2.66; p < 0.001), and lower Revised Trauma Scores (RTS) (0.5 vs. 7.49 vs. 7.83; p < 0.001). Lack of restraint use in the pregnant population is associated with increased MD. Although not validated in the pregnant population, the ISS and RTS were associated with maternal mortality outcomes.

Dr. Robert J. White (1926-2010) was an eminent neurosurgeon and bioethicist, renowned for his classic work in hypothermia and pioneering mammalian head transplant experiments. He founded the Division of Neurosurgery at the Cleveland Metropolitan General Hospital (currently MetroHealth Medical Center, a level 1 trauma county hospital) and became the youngest full professor at the Case Western Reserve University in Cleveland, Ohio. With over 500 research articles to his credit, he founded the Brain Research Laboratory at what was then the Cleveland Metropolitan General Hospital, which was also home to future leaders in neurosurgery, neurosciences, and allied specialties. He transferred a healthy monkey head onto a surgically beheaded monkey body under deep hypothermic conditions drawing both laurels and criticisms alike. Despite a largely controversial neurosurgical research career, his original contributions to deep hypothermia have found profound clinical applications in modern trauma and vascular neurosurgery. The new fusogens and myelorrhaphy methods being tried in Europe hold promise for a future of reanastomosing 2 homologous or heterologous tracts in the neuraxis. Copyright © 2018 Elsevier Inc.

OBJECTIVE To characterize CT findings and outcomes in dogs with head trauma and design a prognostic scale. ANIMALS 27 dogs admitted to the Koret School Veterinary Teaching Hospital within 72 hours after traumatic head injury that underwent CT imaging of the head. PROCEDURES Data were extracted from medical records regarding dog signalment, history, physical and neurologic examination findings, and modified Glasgow coma scale scores. All CT images were retrospectively evaluated by a radiologist unaware of dog status. Short-term (10 days after trauma) and long-term (≥ 6 months after trauma) outcomes were determined, and CT findings and other variables were analyzed for associations with outcome. A prognostic CT-based scale was developed on the basis of the results. RESULTS Cranial vault fractures, parenchymal abnormalities, or both were identified via CT in 24 of 27 (89%) dogs. Three (11%) dogs had only facial bone fractures. Intracranial hemorrhage was identified in 16 (59%) dogs, cranial vault fractures in 15 (56%), midline shift in 14 (52%), lateral ventricle asymmetry in 12 (44%), and hydrocephalus in 7 (26%). Hemorrhage and ventricular asymmetry were significantly and negatively associated with short- and long-term survival, respectively. The developed 7-point prognostic scale included points for hemorrhage, midline shift or lateral ventricle asymmetry, cranial vault fracture, and depressed fracture (1 point each) and infratentorial lesion (3 points). CONCLUSIONS AND CLINICAL RELEVANCE The findings reported here may assist in determining prognoses for other dogs with head trauma. The developed scale may be useful for outcome assessment of dogs with head trauma; however, it must be validated before clinical application.

Investigators reviewed the medical records of all children with minor head trauma, which was defined as a Glasgow coma scale ≥13 at the time of admission to the emergency room, who underwent computed tomography scans during the years of 2013 and 2014. A change in the therapeutic approach was defined as a neurosurgical intervention performed within 30 days, hospitalization, >12 hours of observation, or neuro-specialist evaluation. Of the 1006 children evaluated, 101 showed some abnormality on head computed tomography scans, including 49 who were hospitalized, 16 who remained under observation and 36 who were dismissed. No patient underwent neurosurgery. No statistically significant relationship was observed between patient age, time between trauma and admission, or signs/symptoms related to trauma and abnormal imaging results. A statistically significant relationship between abnormal image results and a fall higher than 1.0 meter was observed (p=0.044). The mean effective dose was 2.0 mSv (0.1 to 6.8 mSv), corresponding to an estimated additional cancer risk of 0.05%. A computed tomography scan after minor head injury in pediatric patients did not show clinically relevant abnormalities that could lead to neurosurgical indications. Patients who fell more than 1.0 m were more likely to have changes in imaging tests, although these changes did not require neurosurgical intervention; therefore, the use of computed tomography scans may be questioned in this group. The results support the trend of more careful indications for cranial computed tomography scans for children with minor head trauma.

Vertebro-vertebral arteriovenous fistulae occur infrequently. We report on such a case with delayed presentation following penetrating neck injury. This was successfully treated via coil embolisation. A 40-year-old woman presented with a subjective tinnitus that was abolished by turning her head to the right. She had sustained penetrating neck trauma 6 months earlier. Doppler Ultrasound and magnetic resonance angiogram confirmed the presence of a vertebral arterio-venous fistula. Using a trans-femoral arterial approach, the left vertebral artery was embolised by deployment of multiple coils. The patient had no return of symptoms at 3 months follow up. Radiological diagnosis and endovascular management of this condition is discussed. PMID:22470664

Ellis, Michael J; Cordingley, Dean; Girardin, Richard; Ritchie, Lesley; Johnston, Janine

The evaluation and management of athletes presenting with clinical features of migraine headache with aura in the setting of sports-related head trauma is challenging. We present a case report of a 15-yr-old boy with a history of migraine with visual aura that developed acute visual disturbance and headache after a head injury during an ice hockey game. The patient underwent comprehensive assessment at a multidisciplinary concussion program, including neuro-ophthalmological examination, neurocognitive testing, and graded aerobic treadmill testing. Clinical history and multidisciplinary assessment was consistent with the diagnosis of coexisting sports-related concussion and migraine with brainstem aura. The authors discuss the pearls and pitfalls of managing patients who develop migraine headache with visual aura after sports-related head injury and the value of a comprehensive multidisciplinary approach to this unique patient population.

Traumatic asphyxia is a rare condition that occurs after compressive thoracoabdominal trauma, which is characterized by subconjunctival hemorrhage, cervicofacial cyanosis, edema and petechiae. Serious life-threatening thoracic and abdominal injuries may coexist. After conservatory treatment in most cases complete recovery is achieved, but in isolated cases permanent neurological lesions may occur. We present the case of the 39-year-old male patient who suffered a compressive thoracoabdominal trauma. The physical examination showed the characteristic "ecchymotic mask". After surgical treatment of the abdominal injuries and intensive therapy the patient was discharged with permanent vision loss. The high retrograde venous pressure in the head and neck may be associated with neuronal ischemia, which can lead to irreversible optic nerve atrophy. It is therefore important to carry out an early, routine and complete ophtalmologic examination, especially in the intubated and poorly cooperative patients. Orv Hetil. 2017; 158(22): 864-868.

Trauma centers need objective feedback on performance to inform quality improvement efforts. The Trauma Quality Improvement Program recently published recommended methodology for case mix adjustment and benchmarking performance. We tested the feasibility of applying this methodology to develop risk-adjusted mortality models for a statewide trauma system. We performed a retrospective cohort study of patients ≥16 years old at Pennsylvania trauma centers from 2011 to 2013 (n = 100,278). Our main outcome measure was observed-to-expected mortality ratios (overall and within blunt, penetrating, multisystem, isolated head, and geriatric subgroups). Patient demographic variables, physiology, mechanism of injury, transfer status, injury severity, and pre-existing conditions were included as predictor variables. The statistical model had excellent discrimination (area under the curve = 0.94). Funnel plots of observed-to-expected identified five centers with lower than expected mortality and two centers with higher than expected mortality. No centers were outliers for management of penetrating trauma, but five centers had lower and three had higher than expected mortality for blunt trauma. It is feasible to use Trauma Quality Improvement Program methodology to develop risk-adjusted models for statewide trauma systems. Even with smaller numbers of trauma centers that are available in national datasets, it is possible to identify high and low outliers in performance. PMID:28541852

Summary Introduction For children who present to emergency departments (EDs) due to blunt head trauma, ED clinicians must decide who requires computed tomography (CT) scanning to evaluate for traumatic brain injury (TBI). The Pediatric Emergency Care Applied Research Network (PECARN) derived and validated two age-based prediction rules to identify children at very low risk of clinically-important traumatic brain injuries (ciTBIs) who do not typically require CT scans. In this case report, we describe the strategy used to implement the PECARN TBI prediction rules via electronic health record (EHR) clinical decision support (CDS) as the intervention in a multicenter clinical trial. Methods Thirteen EDs participated in this trial. The 10 sites receiving the CDS intervention used the Epic® EHR. All sites implementing EHR-based CDS built the rules by using the vendor’s CDS engine. Based on a sociotechnical analysis, we designed the CDS so that recommendations could be displayed immediately after any provider entered prediction rule data. One central site developed and tested the intervention package to be exported to other sites. The intervention package included a clinical trial alert, an electronic data collection form, the CDS rules and the format for recommendations. Results The original PECARN head trauma prediction rules were derived from physician documentation while this pragmatic trial led each site to customize their workflows and allow multiple different providers to complete the head trauma assessments. These differences in workflows led to varying completion rates across sites as well as differences in the types of providers completing the electronic data form. Site variation in internal change management processes made it challenging to maintain the same rigor across all sites. This led to downstream effects when data reports were developed. Conclusions The process of a centralized build and export of a CDS system in one commercial EHR system successfully supported a multicenter clinical trial. PMID:27437059

Blunt ballistic impact trauma is a current research topic due to the widespread use of kinetic energy munitions in law enforcement. In the civilian setting, an automatic dummy launcher has recently been identified as source of blunt impact trauma. However, there is no data on the injury risk of conventional dummy launchers. It is the aim of this investigation to predict potential impact injury to the human head and chest on the basis of the Blunt Criterion which is an energy based blunt trauma model to assess vulnerability to blunt weapons, projectile impacts, and behind-armor-exposures. Based on experimentally investigated kinetic parameters, the injury risk of two commercially available gundog retrieval devices (Waidwerk Telebock, Germany; Turner Richards, United Kingdom) was assessed using the Blunt Criterion trauma model for blunt ballistic impact trauma to the head and chest. Assessing chest impact, the Blunt Criterion values for both shooting devices were higher than the critical Blunt Criterion value of 0.37, which represents a 50% risk of sustaining a thoracic skeletal injury of AIS 2 (moderate injury) or AIS 3 (serious injury). The maximum Blunt Criterion value (1.106) was higher than the Blunt Criterion value corresponding to AIS 4 (severe injury). With regard to the impact injury risk to the head, both devices surpass by far the critical Blunt Criterion value of 1.61, which represents a 50% risk of skull fracture. Highest Blunt Criterion values were measured for the Turner Richards Launcher (2.884) corresponding to a risk of skull fracture of higher than 80%. Even though the classification as non-guns by legal authorities might implicate harmlessness, the Blunt Criterion trauma model illustrates the hazardous potential of these shooting devices. The Blunt Criterion trauma model links the laboratory findings to the impact injury patterns of the head and chest that might be expected. Copyright © 2010 Elsevier Ireland Ltd. All rights reserved.

Objectives Cumulative head trauma may alter brain structure and function. We explored the relationship between exposure variables, cognition and MRI brain structural measures in a cohort of professional combatants. Methods 224 fighters (131 mixed martial arts fighters and 93 boxers) participating in the Professional Fighters Brain Health Study, a longitudinal cohort study of licensed professional combatants, were recruited, as were 22 controls. Each participant underwent computerised cognitive testing and volumetric brain MRI. Fighting history including years of fighting and fights per year was obtained from self-report and published records. Statistical analyses of the baseline evaluations were applied cross-sectionally to determine the relationship between fight exposure variables and volumes of the hippocampus, amygdala, thalamus, caudate, putamen. Moreover, the relationship between exposure and brain volumes with cognitive function was assessed. Results Increasing exposure to repetitive head trauma measured by number of professional fights, years of fighting, or a Fight Exposure Score (FES) was associated with lower brain volumes, particularly the thalamus and caudate. In addition, speed of processing decreased with decreased thalamic volumes and with increasing fight exposure. Higher scores on a FES used to reflect exposure to repetitive head trauma were associated with greater likelihood of having cognitive impairment. Conclusions Greater exposure to repetitive head trauma is associated with lower brain volumes and lower processing speed in active professional fighters. PMID:25633832

Background: Injuries to humans caused by attacks from large predators are very rare, especially in the United States, Europe, or Latin America. A few cases were reported on accidents in zoos or animal farms, being very uncommon in children. The purposes of this report include describing the case of a child who sustained an attack by a lion named “Bang-Bang”, which resulted in injuries to the head, chest, and abdomen, as well as the subsequent neurosurgical treatment and providing a review of the literature. Case Description: We report the case of an 8-year-old boy who was attacked by a lion during a circus show. The patient underwent an emergent neurosurgical procedure, including parietal craniectomy, cleaning, and extensive surgical debridement of the wounds. Despite open severe head trauma with brain damage as well as thorax and abdomen trauma, the child survived, with minimal neurological sequelae. Conclusions: Human injury resulting from encounters with nondomesticated animals is increasingly rising throughout the world. This case highlights the potentially violent and aggressive nature of wild mammals held in captivity. Unusual wild animal attacks and the complex injuries that result may pose a challenge to surgeons practicing in resource-limited settings. In this sense, the best treatment in the mentioned case is the prevention of human injuries by these animals. In addition, to attend to these infrequent cases, the authors emphasize the importance of a multidisciplinary approach to achieve the best cosmetic and functional results. PMID:23869277

In 2003, Seattle implemented an all-ages bicycle helmet law; King County outside of Seattle had implemented a similar law since 1994. For the period 2000-2010, the effect of the helmet legislation on helmet use, helmet-preventable injuries, and bicycle-related fatalities was examined, comparing Seattle to the rest of King County. Data was retrieved from the Washington State Trauma Registry and the King County Medical Examiner. Results comparing the proportions of bicycle related head injuries before (2000-2002) and after (2004-2010) the law show no significant change in the proportion of bicyclists admitted to the hospital and treated for head injuries in either Seattle (37.9 vs 40.2 % p = 0.75) nor in the rest of King County (30.7 vs 31.4 %, p = 0.84) with the extension of the helmet law to Seattle in 2003. However, bicycle-related major head trauma as a proportion of all bicycle-related head trauma did decrease significantly in Seattle (83.9 vs 64.9 %, p = 0.04), while there was no significant change in King County (64.4 vs 57.6 %, p = 0.41). While the results do not show an overall decrease in head injuries, they do reveal a decrease in the severity of head injuries, as well as bicycle-related fatalities, suggesting that the helmet legislation was effective in reducing severe disability and death, contributing to injury prevention in Seattle and King County. The promotion of helmet use through an all ages helmet law is a vital preventative strategy for reducing major bicycle-related head trauma.

Retroclival collections are rare lesions reported almost exclusively in children and strongly associated with trauma. We examine the incidence and imaging characteristics of retroclival collections in young children with abusive head trauma. We conducted a database search to identify children with abusive head trauma ≤ 3 years of age with brain imaging performed between 2007 and 2013. Clinical data and brain images of 65 children were analyzed. Retroclival collections were identified in 21 of 65 (32%) children. Ten (48%) were subdural, 3 (14%) epidural, 2 (10%) both, and 6 (28%) indeterminate. Only 8 of 21 retroclival collections were identifiable on CT and most were low or intermediate in attenuation. Eighteen of 21 retroclival collections were identifiable on MRI: 3 followed cerebral spinal fluid in signal intensity and 15 were bloody/proteinaceous. Additionally, 2 retroclival collections demonstrated a fluid-fluid level and 2 enhanced in the 5 children who received contrast material. Sagittal T1-weighted images, sagittal fluid-sensitive sequences, and axial FLAIR (fluid-attenuated inversion recovery) images showed the retroclival collections best. Retroclival collections were significantly correlated with supratentorial and posterior fossa subdural hematomas and were not statistically correlated with skull fracture or parenchymal brain injury. Retroclival collections, previously considered rare lesions strongly associated with accidental injury, were commonly identified in this cohort of children with abusive head trauma, suggesting that retroclival collections are an important component of the imaging spectrum in abusive head trauma. Retroclival collections were better demonstrated on MRI than CT, were commonly identified in conjunction with intracranial subdural hematomas, and were not significantly correlated with the severity of brain injury or with skull fractures.

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.

Trauma scoring systems and databases.

Lecky, F; Woodford, M; Edwards, A; Bouamra, O; Coats, T

2014-08-01

This review considers current trauma scoring systems and databases and their relevance to improving patient care. Single physiological measures such as systolic arterial pressure have limited ability to diagnose severe trauma by reflecting raised intracranial pressure, or significant haemorrhage. The Glasgow coma score has the greatest prognostic value in head-injured and other trauma patients. Trauma triage tools and imaging decision rules-using combinations of physiological cut-off measures with mechanism of injury and other categorical variables-bring both increased sophistication and increased complexity. It is important for clinicians and managers to be aware of the diagnostic properties (over- and under-triage rates) of any triage tool or decision rule used in their trauma system. Trauma registries are able to collate definitive injury descriptors and use survival prediction models to guide trauma system governance, through individual patient review and case-mix-adjusted benchmarking of hospital and network performance with robust outlier identification. Interrupted time series allow observation in the changes in care processes and outcomes at national level, which can feed back into clinical quality-based commissioning of healthcare. Registry data are also a valuable resource for trauma epidemiological and comparative effectiveness research studies. © The Author 2014.

2012-01-01

To identify predictors of abdominal injuries in victims of blunt trauma. retrospective analysis of trauma protocols (collected prospectively) of adult victims of blunt trauma in a period of 15 months. Variables were compared between patients with abdominal injuries (AIS>0) detected by computed tomography or/and laparotomy (group I) and others (AIS=0, group II). Student's t, Fisher and qui-square tests were used for statistical analysis, considering p<0.05 as significant. A total of 3783 cases were included, with a mean age of 39.1 ± 17.7 years (14-99), 76.1% being male. Abdominal injuries were detected in 130 patients (3.4%). Patients sustaining abdominal injuries had significantly lower mean age (35.4 + 15.4 vs. 39.2 + 17.7), lower mean systolic blood pressure on admission (114.7 + 32.4 mmHg vs. 129.1 + 21.7 mmHg), lower mean Glasgow coma scale (12.9 + 3.9 vs. 14.3 + 2.0), as well as higher head AIS (0.95 + 1.5 vs. 0.67 + 1.1), higher thorax AIS (1.10 + 1.5 vs. 0.11 + 0.6) and higher extremities AIS (1.70 ± 1.8 vs. 1.03 ± 1.2). Patients sustaining abdominal injuries also presented higher frequency of severe injuries (AIS>3) in head (18.5% vs. 7.9%), thorax (29.2% vs. 2.4%) and extremities (40.0% vs. 13.7%). The highest odds ratios for the diagnosis of abdominal injuries were associated flail chest (21.8) and pelvic fractures (21.0). Abdominal injuries were more frequently observed in patients with hemodynamic instability, changes in Glasgow coma scale and severe lesions to the head, chest and extremities.

Blast injury prevalence in skeletal remains: Are there differences between Bosnian war samples and documented combat-related deaths?

Court cases at the International Criminal Tribunal for the Former Yugoslavia (ICTY) have seen questions raised about the recognition and causes of blast-related trauma and the relationship to human rights abuses or combat. During trials, defence teams argued that trauma was combat related and prosecutors argued that trauma was related to executions. We compared a sample of 81 cases (males between 18 and 75) from a Bosnian mass grave investigation linked to the Kravica warehouse killings to published combat-related blast injury data from World War One, Vietnam, Northern Ireland, the first Gulf War, Operation Iraqi Freedom and Afghanistan. We also compared blast fracture injuries from Bosnia to blast fracture injuries sustained in bombings of buildings in two non-combat 'civilian' examples; the Oklahoma City and Birmingham pub bombings. A Chi-squared statistic with a Holm-Bonferroni correction assessed differences between prevalence of blast-related fractures in various body regions, where data were comparable. We found statistically significant differences between the Bosnian and combat contexts. We noted differences in the prevalence of head, torso, vertebral area, and limbs trauma, with a general trend for higher levels of more widespread trauma in the Bosnian sample. We noted that the pattern of trauma in the Bosnian cases resembled the pattern from the bombing in buildings civilian contexts. Variation in trauma patterns can be attributed to the influence of protective armour; the context of the environment; and the type of munition and its injuring mechanism. Blast fracture injuries sustained in the Bosnian sample showed patterns consistent with a lack of body armour, blast effects on people standing in enclosed buildings and the use of explosive munitions.

Evaluate the rate of, and risk factors for, abusive head trauma (AHT) among infants born to military families and compare with civilian population rates. Electronic International Classification of Diseases data from the US Department of Defense (DoD) Birth and Infant Health Registry were used to identify infants born to military families from 1998 through 2005 (N = 676 827) who met the study definition for AHT. DoD Family Advocacy Program data were used to identify infants with substantiated reports of abuse. Rates within the military were compared with civilian population rates by applying an alternate AHT case definition used in a civilian study. Applying the study definition, the estimated rate of substantiated military AHT was 34.0 cases in the first year of life per 100 000 live births. Using the alternate case definition, the estimated AHT rate was 25.6 cases per 100 000 live births. Infant risk factors for AHT included male sex, premature birth, and a diagnosed major birth defect. Parental risk factors included young maternal age (<21 years), lower sponsor rank or pay grade, and current maternal military service. This is the first large database study of AHT with the ability to link investigative results to cases. Overall rates of AHT were consistent with civilian populations when using the same case definition codes. Infants most at risk, warranting special attention from military family support programs, include infants with parents in lower military pay grades, infants with military mothers, and infants born premature or with birth defects.

Cerebral fat embolism and the "starfield" pattern: a case report.

PubMed

Aravapalli, Amit; Fox, James; Lazaridis, Christos

2009-11-19

Nearly all long-bone fractures are accompanied by some form of fat embolism. The rare complication of clinically significant fat embolism syndrome, however, occurs in only 0.9-2.2% of cases. The clinical triad of fat embolism syndrome consists of respiratory distress, altered mental status, and petechial rash. Cerebral fat embolism causes the neurologic involvement seen in fat embolism syndrome. A 19-year-old African-American male was admitted with gunshot wounds to his right hand and right knee. He had diffuse hyperactive deep tendon reflexes, bilateral ankle clonus and decerebrate posturing with a Glasgow Coma Scale (GCS) score of 4T. Subsequent MRI of the brain showed innumerable punctate areas of restricted diffusion consistent with "starfield" pattern. On a 10-week follow up he has a normal neurological examination and he is discharged home. Despite the severity of the neurologic insult upon initial presentation, the majority of case reports on cerebral fat embolism illustrate that cerebral dysfunction associated with cerebral fat embolism is reversible. When neurologic deterioration occurs in the non-head trauma patient, then a systemic cause such as fat emboli should be considered. We describe a patient with non-head trauma who demonstrated the classic "starfield" pattern on diffusion-weighted MRI imaging.

Forensic investigation into a death: post-traumatic amnesia in a worker with a work-related head injury sustained in a coal-fired thermal power plant in India.

Muralidhar, Venkiteswaran

2017-03-15

This is the first reported case of a work-related head injury in a coal-fired thermal power plant in India. This case highlights the trend of not reporting work injuries due to fears of reprisal from the management team that may include the termination of employment. Post-traumatic amnesia in a worker presenting with head trauma must be recognised by coworkers, so the cause of injury can be elicited early and the victim gets timely medical help. There are few published studies on work-related traumatic brain injury, and they provide no information on either anatomical localisation or signs and symptoms. It is imperative that this under-researched area is studied, so detailed epidemiology and accurate national and global statistics are made available to address this dangerous yet preventable condition. 2017 BMJ Publishing Group Ltd.

The practice of facial trauma surgery would benefit from a useful quantitative scale that measures the extent of injury. To develop a facial trauma scale that incorporates only reducible fractures and is able to be reliably communicated to health care professionals. A cadaveric tissue study was conducted from October 1 to 3, 2014. Ten cadaveric heads were subjected to various degrees of facial trauma by dropping a fixed mass onto each head. The heads were then imaged with fine-cut computed tomography. A Bony Facial Trauma Scale (BFTS) for grading facial trauma was developed based only on clinically relevant (reducible) fractures. The traumatized cadaveric heads were then scored using this scale as well as 3 existing scoring systems. Regression analysis was used to determine correlation between degree of incursion of the fixed mass on the cadaveric heads and trauma severity as rated by the scoring systems. Statistical analysis was performed to determine correlation of the scores obtained using the BFTS with those of the 3 existing scoring systems. Scores obtained using the BFTS were not correlated with dentition (95% CI, -0.087 to 1.053; P = .08; measured as absolute number of teeth) or age of the cadaveric donor (95% CI, -0.068 to 0.944; P = .08). Facial trauma scores. Among all 10 cadaveric specimens (9 male donors and 1 female donor; age range, 41-87 years; mean age, 57.2 years), the facial trauma scores obtained using the BFTS correlated with depth of penetration of the mass into the face (odds ratio, 4.071; 95% CI, 1.676-6.448) P = .007) when controlling for presence of dentition and age. The BFTS scores also correlated with scores obtained using 3 existing facial trauma models (Facial Fracture Severity Scale, rs = 0.920; Craniofacial Disruption Score, rs = 0.945; and ZS Score, rs = 0.902; P < .001 for all 3 models). In addition, the BFTS was found to have excellent interrater reliability (0.908; P = .001), which was similar to the interrater reliability of the other 3 tested trauma scales. Scores obtained using the BFTS were not correlated with dentition (odds ratio, .482; 95% CI, -0.087 to 1.053; P = .08; measured as absolute number of teeth) or age of the cadaveric donor (odds ratio, .436; 95% CI, -0.068 to 0.944; P = .08). Facial trauma severity as measured by the BFTS correlated with depth of penetration of the fixed mass into the face. In this study, the BFTS was clinically relevant, had high fidelity in communicating the fractures sustained in facial trauma, and correlated well with previously validated models. NA.

[Diagnostic approach to the mild head trauma of the adult in Emergency Medicine: between biomarkers and imaging].

Lippi, Giuseppe; Cervellin, Gianfranco

Head trauma is one of the most frequent disabling diseases, with annual incidence of approximately 250-600 patients per 100,000, and mortality of 17 cases per 100,000. The mild head injury is nearly 15 times more frequent than the moderate, and more than 20 times than the severe. Although there are still contradictions regarding the clinical significance of the term "head injury", it can not be considered synonymous with traumatic brain injury. The main challenge in the diagnosis lies in the fact that severe intracranial lesions are often associated with mild head injury, especially in the presence of specific risk factors. Despite the diagnostic gold standard is represented by computed tomography (CT), its systematic performance in all patients is unadvisable for limited prevalence of positivity, radiological risk, high cost and complexity. Several potential biomarkers have been proposed for the screening of patients, but protein S100B seems now the most promising for some clinical and analytical considerations. After performing a meta-analysis of clinical trials in patients with mild head injury, we calculated a cumulative area under the curve of 0.753 (95% CI, 0.752-0.754), a negative predictive value of 97.7% (95% CI, 97.5-97.8 %) and positive predictive value of 23.6% (95% CI, 23.2-24.0%) for brain injury. We therefore developed a diagnostic algorithm based on the preliminary assessment of the Glasgow Coma Scale (GCS). Patients with GCS ​​<14 are subjected to CT, those with values GCS​14-15 without risk factors are discharged, whereas protein S100B is assessed stat in those with GCS ​​14-15 and the presence of risk factors. According to the value of the marker, patients with a concentration below the diagnostic cut-offs are discharged, whereas CT is performed in those with higher concentrations. By combining the percentage of positive CT scans in patients with mild head trauma and the negative predictive value of protein S100B, this protocol would safely abate unnecessary CT by 30-50% and costs by 28%.

Central nervous system (CNS) related injuries and exsanguination have been the most common causes of death in trauma for decades. Despite improvements in haemorrhage control in recent years exsanguination is still a major cause of death. We conducted a prospective database study to investigate the current incidence of haemorrhage related mortality. A prospective database study of all trauma patients admitted to an urban major trauma centre between January 2007 and December 2016 was conducted. All in-hospital trauma deaths were included. Cause of death was reviewed by a panel of trauma surgeons. Patients who were dead on arrival were excluded. Trends in demographics and outcome were analysed per year. Further, 2 time periods (2007-2012 and 2013-2016) were selected representing periods before and after implementation of haemostatic resuscitation and damage control procedures in our hospital to analyse cause of death into detail. 11,553 trauma patients were admitted, 596 patients (5.2%) died. Mean age of deceased patients was 61 years and 61% were male. Mechanism of injury (MOI) was blunt in 98% of cases. Mean ISS was 28 with head injury the most predominant injury (mean AIS head 3.4). There was no statistically significant difference in sex and MOI over time. Even though deceased patients were older in 2016 compared to 2007 (67 vs. 46 years, p < 0.001), mortality was lower in later years (p = 0.02). CNS related injury was the main cause of death in the whole decade; 58% of patients died of CNS in 2007-2012 compared to 76% of patients in 2013-2016 (p = 0.001). In 2007-2012 9% died of exsanguination compared to 3% in 2013-2016 (p = 0.001). In this cohort in a major trauma centre death by exsanguination has decreased to 3% of trauma deaths. The proportion of traumatic brain injury has increased over time and has become the most common cause of death in blunt trauma. Besides on-going prevention of brain injury future studies should focus on treatment strategies preventing secondary damage of the brain once the injury has occurred. Copyright © 2018 Elsevier Ltd.

Head trauma in sport and neurodegenerative disease: an issue whose time has come?

PubMed

Pearce, Neil; Gallo, Valentina; McElvenny, Damien

2015-03-01

A number of small studies and anecdotal reports have been suggested that sports involving repeated head trauma may have long-term risks of neurodegenerative disease. There are now plausible mechanisms for these effects, and a recognition that these problems do not just occur in former boxers, but in a variety of sports involving repeated concussions, and possibly also in sports in which low-level head trauma is common. These neurodegenerative effects potentially include increased risks of impaired cognitive function and dementia, Parkinson's disease, and amyotrophic lateral sclerosis. Many would argue for taking a precautionary approach and immediately banning or restricting sports such as boxing. However, there are important public health issues in terms of how wide the net should be cast in terms of other sports, and what remedial measures could be taken? This in turn requires a major research effort involving both clinical and basic research to understand the underlying mechanisms, leading from head trauma to neurodegenerative disease and epidemiologic studies to assess the long-term consequences.

Conservative vs. Surgical Management of Post-Traumatic Epidural Hematoma: A Case and Review of Literature

PubMed Central

Maugeri, Rosario; Anderson, David Greg; Graziano, Francesca; Meccio, Flavia; Visocchi, Massimiliano; Iacopino, Domenico Gerardo

2015-01-01

Patient: Male, 30 Final Diagnosis: Acute epidural hematoma Symptoms: — Medication: — Clinical Procedure: Observation Specialty: Neurosurgery Objective: Unusual clinical course Background: Trauma is the leading cause of death in people younger than 45 years and head injury is the main cause of trauma mortality. Although epidural hematomas are relatively uncommon (less than 1% of all patients with head injuries and fewer than 10% of those who are comatose), they should always be considered in evaluation of a serious head injury. Patients with epidural hematomas who meet surgical criteria and receive prompt surgical intervention can have an excellent prognosis, presumably owing to limited underlying primary brain damage from the traumatic event. The decision to perform a surgery in a patient with a traumatic extraaxial hematoma is dependent on several factors (neurological status, size of hematoma, age of patients, CT findings) but also may depend on the judgement of the treating neurosurgeon. Case Report: A 30-year old man arrived at our Emergency Department after a traumatic brain injury. General examination revealed severe headache, no motor or sensory disturbances, and no clinical signs of intracranial hypertension. A CT scan documented a significant left fronto-parietal epidural hematoma, which was considered suitable for surgical evacuation. The patient refused surgery. Following CT scan revealed a minimal increase in the size of the hematoma and of midline shift. The neurologic examination maintained stable and the patient continued to refuse the surgical treatment. Next follow up CT scans demonstrated a progressive resorption of hematoma. Conclusions: We report an unusual case of a remarkable epidural hematoma managed conservatively with a favorable clinical outcome. This case report is intended to rather add to the growing knowledge regarding the best management for this serious and acute pathology. PMID:26567227

Effect of gamma-hydroxybutyric acid on tissue Na+,K- ATPase levels after experimental head trauma.

PubMed

Yosunkaya, A; Ustün, M E; Bariskaner, H; Tavlan, A; Gürbilek, M

2004-05-01

A failure of the Na(+),K(+)-ATPase activity (which is essential for ion flux across the cell membranes) occurs in many pathological conditions and may lead to cell dysfunction or even cell death. By altering the concentration of specific opioid peptides, gamma-hydroxybutyric acid (GHB) may change ion flux across cell membranes and produce the 'channel arrest' which we assumed will inhibit the failure of Na+,K(+)-ATPase activity and therefore lead to energy conservation and cell protection. Therefore we planned this study to see the effects of GHB at two different doses on Na(+),K(+)-ATPase activity in an experimental head trauma model. Forty New Zealand rabbits were divided equally into four groups: group I was the sham-operated group, group II (untreated group), group III received head trauma and intravenous (i.v.) 500 mg/kg GHB and group IV received head trauma and i.v. 50 mg/kg GHB. Head trauma was delivered by performing a craniectomy over the right hemisphere and dropping a weight of 10 g from a height of 80 cm. The non-traumatized (left) side was named as 'a' and the traumatized (right) side as 'b'. One hour after the trauma in groups II and III and craniotomy in group I, brain cortices were resected from both sides and in group I only from the right side was the tissue Na-K-ATPase activity determined. The mean +/- SD of Na(+),K(+)-ATPase levels of each group are as follows: group I - 5.97 +/- 0.55; group IIa - 3.90 +/- 1.08; group IIb - 3.58 +/- 0.90; group IIIa - 5.53 +/- 0.60; group IIIb - 5.33 +/- 0.88; group IVa - 5.05 +/- 0.72; group IVb - 4.93 +/- 0.67. The Na(+),K(+)-ATPase levels of group IIa, IIb, IVa and IVb were significantly different from group S (P < 0.05). There were also significant differences between group IIa and groups IIIa and IVa; group IIb and groups IIIb and IVb (P < 0.05). We conclude that GHB is effective in suppressing the decrease in Na(+),K(+)-ATPase levels in brain tissue at two different dose schedules after head trauma.

Paediatric trauma has become a major cause of mortality, disability and socioeconomic burden in developing countries and the World Health Organization (WHO) projects that by 2020 it will be the leading disease globally. This study described the pattern of paediatric injuries seen at a regional trauma center in North West, Nigeria. Trauma centre of a tertiary hospital in North-Western Nigeria. A retrospective look at the trauma register for records of paediatric trauma from January to December 2010 was performed. Information obtained include age and sex, causes and pattern of injury. The limit of 16 years was set for paediatric in our centre. The numbers of paediatric trauma seen over the 12-month period were 567 out of a total of 3984 trauma cases representing 14.2%. The number of males was 407(71.8%) and females were 160(28.2%) with M: F ratio of 2.5:1. The mean age was 7.77 and standard deviation of 0.19. Road Traffic Accidents (RTA) and Domestic injuries representing 44.8 and 42.0%, respectively, were the commonest causes of injuries. Laceration and bruises, head injuries including extremities were the commonest types of injuries seen. Road traffic accidents and domestic injuries as common causes of paediatric trauma need to be 'addressed by the authorities' so as to reduce the burden of trauma on the vulnerable children in our society.

The authors sought to determine whether 3,3-bis (3-fluorophenyl) propylamine (NPS 846), a novel noncompetitive N-methyl-D-aspartate receptor antagonist, alters outcome after closed head trauma in rats. The experimental variables were: presence or absence of closed head trauma, treatment with NPS 846 or no treatment, and time at which the rats were killed (24 or 48 hours). The NPS 846 (1 mg/kg) was administered intraperitoneally at 1 and 3 hours after closed head trauma or sham operation. Outcome measures were the neurological severity score (NSS), ischemic tissue volume, hemorrhagic necrosis volume, and specific gravity, water content, and concentrations of calcium, sodium, potassium, and magnesium in brain tissue. The following closed head trauma-induced changes in the injured hemisphere (expressed as the mean +/- the standard deviation) were reversed by NPS 846: decreased specific gravity of 1.035 +/- 0.006 at 24 hours was increased to 1.042 +/- 0.004; the decreased potassium level of 0.583 +/- 0.231 mg/L at 48 hours and at 24 hours was increased to 2.442 +/- 0.860 mg/L; the increased water content of 84.7 +/- 2.6% at 24 hours was decreased to 79.8 +/- 2%; the increased calcium level of 0.592 +/- 0.210 mg/L at 24 hours was decreased to 0.048 +/- 0.029 mg/L; and the increased sodium level of 2.035 +/- 0.649 mg/L was decreased to 0.631 +/- 0.102 mg/L. Administration of NPS 846 also lowered the NSS (improved neurological status) at 48 hours (7 +/- 3) and caused no significant changes in ischemic tissue or hemorrhagic necrosis volumes in the injured hemisphere at 24 or 48 hours. In this model of closed head trauma, NPS 846 improved neurological outcome, delayed the onset of brain edema, and improved brain tissue ion homeostasis.

Brainstem haemorrhage is common in cases of head injury when it is associated with space-occupying lesion and increases in the intracranial pressure (duret haemorrhage), in cases of diffuse axonal injury (in dorso-lateral quadrant) and diffuses vascular injury (in the periventricular tissue). However focal traumatic brainstem injury is rare. We identified 12 cases of focal traumatic brainstem injury from review of 319 case of head injury. The head trauma had been caused by different mechanisms of complex fall from height and assault. 10/12 are associated with skull fracture, 11/12 with contre coup contusions in the frontal and temporal lobes, 5/12 direct contusions to cerebellum, 5/12 haemorrhage in corpus callosum and 2/11 have gliding contusions. None of the cases had pathological evidence of increase in the intracranial pressure. The bleeding in the pons was at the edge in 2/12 and cross the section in 10/12. The majority of patients were unconscious immediately after the incident (10/12) and 9/12 died within one day. Focal traumatic brainstem injury occurs most likely due to direct impact at the back of the head or stretching forces affecting the brainstem in cases of complex fall from height and after assault, particularly those associated with kicks. It is a serious and commonly fatal brain damage, which needed to be differentiated from other causes of brainstem haemorrhages.

Right sided weakness with right subdural hematoma: motor deafferentation of left hemisphere resulted in paralysis of the right side.

PubMed

Derakhshan, Iraj

2009-08-01

A right handed man with trauma to the head was admitted with headache and seizures. A severe right sided weakness was noted after a blunt trauma to the right side of his head. MRI of brain revealed a right-sided subdural hematoma and a normal left hemisphere and downstream motor pathways. Bimanual simultaneous drawing and manual reaction times indicated that the patient was right hemispheric in laterality of his major hemisphere. The right sided weakness in this patient was due to temporary transcallosal disconnection (diaschisis) of the minor hemisphere (left, in this case) from the excitatory signals arising from those structures of his major hemisphere devoted to movements occurring on nondominant side, transmitted via the corpus callosum to his left hemisphere. This case draws attention to disparity between neural and behavioral handedness (laterality of major hemisphere versus that of the preferred hand). Drawing longer lines by the left hand in simultaneous bimanual tasks and a slower simple reaction time to central visual stimuli by the ostensible dominant hand permitted lateralization of the major hemisphere to the right. Thus, the neurally nondominant side (right) lagged behind the dominant (left) by an interval equal to interhemispheric transfer time.

Objectives This study examined the performance of serum glial fibrillary acidic protein (GFAP) in detecting traumatic intracranial lesions on computed tomography (CT) scan in children and youth with mild and moderate traumatic brain injury (TBI), and assessed its performance in trauma control patients without head trauma. Methods This prospective cohort study enrolled children and youth presenting to three Level I trauma centers following blunt head trauma with Glasgow Coma Scale (GCS) scores of 9 to 15, as well as trauma control patients with GCS scores of 15 who did not have blunt head trauma. The primary outcome measure was the presence of intracranial lesions on initial CT scan. Blood samples were obtained in all patients within six hours of injury and measured by ELISA for GFAP (ng/ml). Results A total of 257 children and youth were enrolled in the study and had serum samples drawn within 6 hours of injury for analysis: 197 had blunt head trauma and 60 were trauma controls. CT scan of the head was performed in 152 patients and traumatic intracranial lesions on CT scan were evident in 18 (11%), all of whom had GCS scores of 13 to 15. When serum levels of GFAP were compared in children and youth with traumatic intracranial lesions on CT scan to those without CT lesions, median GFAP levels were significantly higher in those with intracranial lesions (1.01, IQR 0.59 to 1.48) than those without lesions (0.18, IQR 0.06 to 0.47). The area under the receiver operating characteristic (ROC) curve (AUC) for GFAP in detecting children and youth with traumatic intracranial lesions on CT was 0.82 (95% CI = 0.71 to 0.93). In those presenting with GCS scores of 15, the AUC for detecting lesions was 0.80 (95% CI = 0.68 to 0.92). Similarly, in children under five years old the AUC was 0.83 (95% CI = 0.56 to 1.00). Performance for detecting intracranial lesions at a GFAP cutoff level of 0.15 ng/ml yielded a sensitivity of 94%, a specificity of 47%, and a negative predictive value of 98%. Conclusions In children and youth of all ages, GFAP measured within 6 hours of injury was associated with traumatic intracranial lesions on CT and with severity of TBI. Further study is required to validate these findings before clinical application. PMID:26469937

OBJECTIVE Intracranial pressure (ICP) monitoring has become the standard of care in the management of severe head trauma. Intraventricular devices (IVDs) and intraparenchymal devices (IPDs) are the 2 most commonly used techniques for ICP monitoring. Despite the widespread use of these devices, very few studies have investigated the effect of device type on outcomes. The purpose of the present study was to compare outcomes between 2 types of ICP monitoring devices in patients with isolated severe blunt head trauma. METHODS This retrospective observational study was based on the American College of Surgeons Trauma Quality Improvement Program database, which was searched for all patients with isolated severe blunt head injury who had an ICP monitor placed in the 2-year period from 2013 to 2014. Extracted variables included demographics, comorbidities, mechanisms of injury, head injury specifics (epidural, subdural, subarachnoid, intracranial hemorrhage, and diffuse axonal injury), Abbreviated Injury Scale (AIS) score for each body area, Injury Severity Score (ISS), vital signs in the emergency department, and craniectomy. Outcomes included 30-day mortality, complications, number of ventilation days, intensive care unit and hospital lengths of stay, and functional independence. RESULTS During the study period, 105,721 patients had isolated severe traumatic brain injury (head AIS score ≥ 3). Overall, an ICP monitoring device was placed in 2562 patients (2.4%): 1358 (53%) had an IVD and 1204 (47%) had an IPD. The severity of the head AIS score did not affect the type of ICP monitoring selected. There was no difference in the median ISS; ISS > 15; head AIS Score 3, 4, or 5; or the need for craniectomy between the 2 device groups. Unadjusted 30-day mortality was significantly higher in the group with IVDs (29% vs 25.5%, p = 0.046); however, stepwise logistic regression analysis showed that the type of ICP monitoring was not an independent risk factor for death, complications, or functional outcome at discharge. CONCLUSIONS This study demonstrated that compliance with the Brain Trauma Foundation guidelines for ICP monitoring is poor. In isolated severe blunt head injuries, the type of ICP monitoring device does not have any effect on survival, systemic complications, or functional outcome.

The number of polytrauma patient with associated brain injury or commonly referred as 'head injury' has increased tremendously in recent times courtesy to road traffic accident or other causes. This prospective observational study was conducted in patients of head injury admitted through emergency in the department of general surgery in NRS Medical College, Kolkata during the year 2011 to determine the pattern of head injury patients admitted and nature of intervention. A total number of 3861 patients were admitted in a single year. Obviously this represents the tip of the iceburg. Traumatic brain injury was the highest in the age group of 31-40 years (33.5%) followed by 21-30 years (29.1%) in the most fruitful phase of life. The traumatic brain injury death was more common in males. The maximum number of cases was from rural areas ie, farmers and labours. To minimise the morbidity and mortality resulting from head injury there is need for better maintenance of roads, improvement of road visibility and lighting, rigid enforcement of traffic rules and imparting road safety education to school children. Despite valiant efforts and advancement in medical sciences and infrastructure in the form of neurosurgery departments and trauma care units to cope with the changing world of trauma, there still remains a huge responsibility and a definite part to be played by the general surgeons to manage head injury patient even in tertiary hospitals.

Long Term Survivorship of a Severely Notched Femoral Stem after Replacing the Fractured Ceramic head with a Cobalt-Chromium Head

Panagopoulos, Andreas; Tatani, Irini; Megas, Panagiotis

2016-01-01

Background: Although ceramic head fracture occurs infrequently today, in the event of a fracture, the resulting revision surgery can prove very challenging, since the ceramic particles lodge into the surrounding soft tissue and can cause rapid implant failure Case Presentation: A case of long term survivorship of a severed notched femoral stem after replacing the fractured femoral head with a cobalt-chromium one is reported in a 40-year old woman with hip dysplasia who underwent an uncomplicated total hip arthroplasty. The incident of ceramic femoral head fracture occurred 14 months postoperatively without reporting any significant trauma. Intraoperative findings at revision were a multifragmented femoral head and a damaged polyethylene insert along with diffuse metallosis and excessive wear of the cone of the stem. Both the stem and the acetabular component were stable. After removal of ceramic fragments, metallotic tissue excision and careful lavage of the joint, the inlay was replaced by a similar one and a cobalt-chromium femoral head was placed to the existing notched taper of the firmly incorporated stem. At the 13th year follow up examination, the patient had no pain, used no walking aids, and had normal activity with no signs of wearing or loosening in the plain x-rays. Conclusion: Despite current recommendations of using ceramic femoral heads in cases of fracture or to revise the severely damaged stems we were able to provide a long term survivorship up to 13 years postoperatively of a cobalt-chromium femoral head applied to a severe damaged stem.

[Efficient imaging of elbow injuries in children and adolescents].

PubMed

Kraus, R; Berthold, L D; von Laer, L

2007-01-01

The purpose of imaging of the elbow region in children after acute trauma is the diagnosis of injuries that require further treatment. Basic diagnostic consists of standard X-rays of the elbow in two planes. Exceptions can be made in the case of nursemaid's elbow lesion (subluxation of the radial head; pronation douloureuse; Chassaignac lesion) with unambiguous mechanism of the trauma where no X-ray imaging is needed and in heavily dislocated fractures for which one plane can be sufficient. X-ray imaging of the uninjured side is obsolete. Follow-up X-ray imaging is only allowed if consequences for the further treatment are expected. Ultrasound may partially replace X-rays in the future if further standardization of this technique can be achieved. MRI provides additional information in acute trauma which, however, remains currently without consequences for the further treatment strategy.

We sought to determine whether the results of audiological tests and tinnitus characteristics, particularly tinnitus pitch and minimum masking level (MML), depend on tinnitus etiology, and what other etiology-specific tinnitus characteristics there are. The patients answered questions concerning tinnitus laterality, duration, character, aggravation, alleviation, previous treatment, and circumstances of onset. The results of tympanometry, pure-tone audiometry, distortion-product otoacoustic emissions, tinnitus likeness spectrum, MML, and uncomfortable loudness level were evaluated. Patients with several tinnitus etiological factors were excluded. The remaining participants were divided into groups according to medical history: acute acoustic trauma: 67 ears; chronic acoustic trauma: 82; prolonged use of oral estrogen and progesterone contraceptives: 46; Ménière's disease: 25; congenital hearing loss: 19; sensorineural sudden deafness: 40; dull head trauma: 19; viral labyrinthitis: 53; stroke: 6; presbycusis: 152. Data of 509 ears were analysed. Tinnitus pitch was highest in patients with acute acoustic trauma and lowest in patients receiving estrogen and progesterone. MML was lowest after acute acoustic trauma and in congenital hearing loss, and highest after a stroke and in the case of presbytinnitus. Tinnitus pitch and MML are etiology dependent.

Here, we report the case of an incidental finding of lamellar calcification of the falx cerebri in a routine computed tomography scan of the head after an accidental trauma. This lamellar calcification led to the diagnosis of Gorlin-Goltz syndrome (GGS) in the patient and her daughter. Lamellar calcification of the falx cerebri is a pathognomonic feature of GGS. Our case report highlights the importance of a multidisciplinary diagnostic approach to GGS.

To evaluate a protocol for rapid sequence intubation (RSI) for pediatric patients in a Level 1 trauma center. Retrospective review of prospectively gathered Continuing Quality Improvement (CQI) data at an inner city Level 1 trauma center with an emergency medicine residency program. Protocols for RSI were established prior to initiating the study. All pediatric intubations at the center from February 1996 to February 2000 were included. Statistical analysis included descriptive statistics for categorical data and Chi-square for comparisons between groups. Over the 4-year study period there were 83 pediatric intubations ranging in age from 18 months to 17 years; mean age 8.6. All had data collected at the time of intubation. There were 20 (24%) females and 62 (76%) males (p<0.001). Reasons for intubation were related to trauma in 71 (86%) and medical reasons in 12 (14%) (p<0.001). Of the trauma intubations 7 (10%) were for gunshot wounds, 39 (55%) were secondary to MVCs, and the remainder (25; 35%) were from assaults, falls, and closed head injuries. The non-trauma intubations were for smoke inhalation, overdose, seizure, HIV related complications, eclampsia, and near drowning. Intubations were successful with one attempt in 65 (78%) cases. No surgical airways were necessary. Rocuronium was used in 4 cases. Protocol deviations did not lead to complications. This protocol based pediatric rapid sequence intubation method worked well in an EM residency program. More intubations were in males and more were necessary due to trauma in this group.

Severe head injury is known to be a major cause of early mortalities and morbidities. Patients' long-term outcome after acute care, however, has not been widely studied. We aim to review the outcome of severely head-injured patients after discharge from acute care at a designated trauma center in Hong Kong. This is a retrospective study of prospectively collected data of patients admitted with severe head injuries between 2004 and 2008. Patients' functional status post-discharge was assessed using the Extended Glasgow Outcome Score (GOSE). Of a total of 1565 trauma patients, 116 had severe head injuries and 41 of them survived acute hospital care. Upon the last follow-up, 23 (56.1%) of the acute-care survivors had improvements in their GOSE, six (11.8%) experienced deteriorations, and 12 (23.5%) did not exhibit any change. The greatest improvement was observed in patients with GOSE of 5 and 6 upon discharge, but two of the 16 patients with GOSE 2 or 3 also had a good recovery. On logistic regression analysis, old age and prolonged acute hospital stay were found to be independent predictors of poor functional outcome after a mean follow-up duration of 42 months. Multidisciplinary neurorehabilitation service is an important component of comprehensive trauma care. Despite significant early mortalities, a proportion of severely head-injured patients who survive acute care may achieve good long-term functional recovery.

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

Effect of the Earned Income Tax Credit on Hospital Admissions for Pediatric Abusive Head Trauma, 1995-2013.

Policies that increase household income, such as the earned income tax credit (EITC), have shown reductions on risk factors for child maltreatment (ie, poverty, maternal stress, depression), but evidence is lacking on whether the EITC actually reduces child maltreatment. We examined whether states' EITCs are associated with state rates of hospital admissions for abusive head trauma among children aged <2 years. We conducted difference-in-difference analyses (ie, pre- and postdifferences in intervention vs control groups) of annual rates of states' hospital admissions attributed to abusive head trauma among children aged <2 years (ie, using aggregate data). We conducted analyses in 14 states with, and 13 states without, an EITC from 1995 to 2013, differentiating refundable EITCs (ie, tax filer gets money even if taxes are not owed) from nonrefundable EITCs (ie, tax filer gets credit only for any tax owed), controlling for state rates of child poverty, unemployment, high school graduation, and percentage of non-Latino white people. A refundable EITC was associated with a decrease of 3.1 abusive head trauma admissions per 100 000 population in children aged <2 years after controlling for confounders ( P = .08), but a nonrefundable EITC was not associated with a decrease ( P = .49). Tax refunds ranged from $108 to $1014 and $165 to $1648 for a single parent working full-time at minimum wage with 1 child or 2 children, respectively. Our findings with others suggest that policies such as the EITC that increase household income may prevent serious abusive head trauma.

Surgical resident rotations on trauma services are criticized for little operative experience and heavy workloads. This has resulted in diminished interest in trauma surgery among surgical residents. Acute care surgery (ACS) combines trauma and emergency/elective general surgery, enhancing operative volume and balancing operative and nonoperative effort. We hypothesize that a mature ACS service provides significant operative experience. A retrospective review was performed of ACGME case logs of 14 graduates from a major, academic, Level I trauma center program during a 3-year period. Residency Review Committee index case volumes during the fourth and fifth years of postgraduate training (PGY-4 and PGY-5) ACS rotations were compared with other service rotations: in total and per resident week on service. Ten thousand six hundred fifty-four cases were analyzed for 14 graduates. Mean cases per resident was 432 ± 57 in PGY-4, 330 ± 40 in PGY-5, and 761 ± 67 for both years combined. Mean case volume on ACS for both years was 273 ± 44, which represented 35.8% (273 of 761) of the total experience and exceeded all other services. Residents averaged 8.9 cases per week on the ACS service, which exceeded all other services except private general surgery, gastrointestinal/minimally invasive surgery, and pediatric surgery rotations. Disproportionately more head/neck, small and large intestine, gastric, spleen, laparotomy, and hernia cases occurred on ACS than on other services. Residents gain a large operative experience on ACS. An ACS model is viable in training, provides valuable operative experience, and should not be considered a drain on resident effort. Valuable ACS rotation experiences as a resident may encourage graduates to pursue ACS as a career. Copyright © 2011 by Lippincott Williams & Wilkins

Chronic traumatic encephalopathy and athletes

2015-01-01

Recent case reports have described athletes previously exposed to repetitive head trauma while participating in contact sports who later in life developed mood disorders, headaches, cognitive difficulties, suicidal ideation, difficulties with speech, and aggressive behavior. Postmortem discoveries show that some of these athletes have pathologic findings that are collectively termed chronic traumatic encephalopathy (CTE). Current hypotheses suggest that concussions or perhaps blows to the head that do not cause the signs and symptoms necessary for making the diagnosis of concussion, so-called subconcussive blows, cause both the clinical and pathologic findings. There are, however, some athletes who participate in contact sports who do not develop the findings ascribed to CTE. Furthermore, there are people who have headaches, mood disorders, cognitive difficulties, suicidal ideation, and other clinical problems who have neither been exposed to repeated head trauma nor possessed the pathologic postmortem findings of those currently diagnosed with CTE. The current lack of prospective data and properly designed case-control studies limits the current understanding of CTE, leading to debate about the causes of the neuropathologic findings and the clinical observations. Given the potential for referral and recall bias in available studies, it remains unclear whether or not the pathologic findings made postmortem cause the presumed neurobehavioral sequela and whether the presumed risk factors, such as sports activity, cerebral concussions, and subconcussive blows, are solely causative of the clinical signs and symptoms. This article discusses the current evidence and the associated limitations. PMID:26253448

Trauma is a major problem in both developing and developed countries. World wide road-traffic injuries (RTIs) represent 25% of all trauma deaths. Injuries cause 12% of the global disease burden and are the third commonest cause of death globally. In our own environment, trauma is also important, with RTIs being a leading cause of morbidity and mortality. There is limited data on RTIs in West African countries, and this necessitated our study. We aimed to find common causative factors and proffer solutions. This was a one year prospective study examining all cases of trauma from RTIs seen at the Accident and Emergency Department of the Ebonyi State University Teaching Hospital (EBSUTH), Abakaliki, Nigeria. Three hundred and sixty-three patients were studied. There was a male/female ratio of 3.4:1, with the modal age being 25 years. Most injuries involved motorcycles (54%). Passengers from cars and buses were also commonly affected (34.2%). Most of accidents occurred from head-on collisions (38.8%). Soft-tissue injuries and fractures accounted for 83.5% of injuries. The head and neck region was the commonest injury site (41.1%), and the most commonly fractured bones were the tibia and fibula (5.8%). Death occurred in 17 patients (4.7%), and 46 (12.7%) patients discharged themselves against medical advice. Improvements in road safety awareness, proper driver education-especially motorcycle drivers-and proper hospital care are needed in our subregion.

We observed some cases of lung abscess (LA) in ICU patients suffering S.aureus ventilator-associated pneumonia (S.aureus-VAP). We aimed to assess which of the host and/or bacteria-related features are associated with LA. We conducted a retrospective study from January 2009 to July 2013 in a trauma surgical ICU within a teaching hospital. All adult patients presenting with S.aureus-VAP were included. We compared two groups of patients according to the formation or not of LA concomitantly to S.aureus-VAP. Seventy-nine S.aureus-VAP patients, predominantly males (85%) of rather young age (mean [SD]: 35yr [21-64]) with severe trauma (initial Simplified Acute Score II = 42 [32-52]) related-ICU admission, were included. Among them, 10 (14%) developed LA. Patient's characteristics significantly associated with LA development were: a younger age (p = 0.003), road traffic accidents admission (p = 0.017), head injury (p = 0.002), lower Glasgow Coma Scale (p = 0.009), blunt chest trauma (p = 0.01) pneumothorax (p = 0.01) and lung contusions (p = 0.002). No microbiological factors were significantly associated with LA formation. Abscesses were mostly bilateral, ≥5 cm of diameter and with a posterior location. Our results do not favor a specific virulence of S.aureus, but rather highlight the role of multiple insults to the lung, promoting LA formation. Despite a similar severity score, patients with LA had more serious trauma, combining severe both chest and head insults.

Links between cervical spine and/or spinal cord injuries and head trauma have not been reported in detail. 188 patients with cervical spine and/or spinal cord injury were divided into two groups, i.e., with upper cervical and mid-lower cervical injury, and compared for head injury. Associated head trauma was investigated in 188 patients with cervical spine and/or spinal cord injuries; 35% had moderate or severe injuries. Brain damage was more frequently observed in patients with upper cervical injury than in those with mid to lower cervical injury. Those patients with upper cervical injury appeared to have an elevated risk of suffering skull base fractures, traumatic subarachnoid hemorrhage, and contusional hemotoma. Approximately one third of patients with cervical spine and/or spinal cord injuries had moderate or severe head injuries. Brain damage was more frequently associated with upper cervical injury. Those patients with upper cervical injury are at greater risk of suffering from skull base fractures and severe intracranial hematomas than those with mid to lower cervical injury.

The goal of the present study was to analyze the epidemiology and specific risk factors of traumatic brain injury (TBI) in the Asterix illustrated comic books. Among the illustrated literature, TBI is a predominating injury pattern. A retrospective analysis of TBI in all 34 Asterix comic books was performed by examining the initial neurological status and signs of TBI. Clinical data were correlated to information regarding the trauma mechanism, the sociocultural background of victims and offenders, and the circumstances of the traumata, to identify specific risk factors. Seven hundred and four TBIs were identified. The majority of persons involved were adult and male. The major cause of trauma was assault (98.8%). Traumata were classified to be severe in over 50% (GCS 3-8). Different neurological deficits and signs of basal skull fractures were identified. Although over half of head-injury victims had a severe initial impairment of consciousness, no case of death or permanent neurological deficit was found. The largest group of head-injured characters was constituted by Romans (63.9%), while Gauls caused nearly 90% of the TBIs. A helmet had been worn by 70.5% of victims but had been lost in the vast majority of cases (87.7%). In 83% of cases, TBIs were caused under the influence of a doping agent called "the magic potion". Although over half of patients had an initially severe impairment of consciousness after TBI, no permanent deficit could be found. Roman nationality, hypoglossal paresis, lost helmet, and ingestion of the magic potion were significantly correlated with severe initial impairment of consciousness (p ≤ 0.05).

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.

In recent conflicts, many UK personnel sustained head injuries requiring damage-control surgery and aeromedical transfer to the UK. This study aims to examine indications, complications and outcomes of UK military casualties undergoing craniectomy and cranioplasty from conflicts in Afghanistan and Iraq. The UK military Joint Theatre Trauma Registry (JTTR) was searched for all UK survivors in Afghanistan and Iraq between 2004 and 2014 requiring craniectomy and cranioplasty resulting from trauma. Fourteen decompressive craniectomies and cranioplasties were performed with blast and gunshot wounds equally responsible for head injury. Ten survivors (71%) had an Injury Severity Score (ISS) of 75, normally designated as 'unsurvivable'. Most were operated on the day of injury. Seventy-one percent received a reverse question mark incision and 7% received a bicoronal incision. Seventy-nine percent had bone flaps discarded. Overall infection rate was 43%. Acinetobacter spp was the causative organism in 50% of cases. Median Glasgow Outcome Scale (GOS) at final follow-up was 4. All casualties had a GOS score greater than 3. Timely neurosurgical intervention is imperative for military personnel given high survival rates in those sustaining what are designated 'un-survivable' injuries. Early decompression facilitates safe aeromedical evacuation of casualties. Excellent outcomes validate the UK military trauma system and the stepwise performance gains throughout recent conflicts however trauma registers most evolving to have specific relevance to military casualties. In high-energy trauma with contamination and soft-tissue destruction, surgery should be conducted with regard for future soft tissue reconstruction. Bone flaps should be discarded and cranioplasty performed according to local preference. Facilities receiving military casualties should have specialist microbiological input mindful of the difficulties treating unusual microbes.

Long Term Consequences: Effects on Normal Development Profile after Concussion

Each year in the United States, approximately 1.7 million people are diagnosed with a traumatic brain injury (TBI); an estimated 75% of these injuries are classified as mild TBIs (mTBI) or concussions. The symptoms of such injuries include a variety of somatic, cognitive, and behavioral deficits. While these symptoms typically resolve in a matter of weeks, both children and adults may suffer from Post-Concussion Syndrome (PCS) for months or longer. Suffering from PCS-related symptoms for an extended time may delay an individual’s return to work, adversely affect one’s quality of life, and result in additional social and economic costs. Though a consensus has not been reached on the cause of long-term PCS, it is likely that biological, physiological, psychological, and social elements all play a role in symptom persistence. Additionally, persistent PCS may adversely affect one’s developmental trajectory. The enduring effects of head trauma are not limited to PCS-related effects, however. A progressive tauopathy, chronic traumatic encephalopathy (CTE) is believed to stem from repeated brain trauma. While CTE was originally associated with boxing, it has recently been found in other cases of repetitive head injury including former football and hockey players, and professional wrestlers. In addition to this observed pathology, repetitive brain trauma is also associated with Alzheimer’s-like dementia, Parkinsonism, and motor neuron disease including Amyotrophic Lateral Sclerosis (ALS). With these significant long-term effects of head injuries, there is a clear need to develop effective diagnoses, treatments, and education plans to reduce future burden and incidence. PMID:22050943

Computed tomography (CT) scans are frequently used in managing traumatic brain injuries in children. To assess incidental findings in children with head trauma undergoing CT scan and to describe any associated clinical ramifications. Retrospective review of 524 children treated in 2 emergency departments for closed head injury who received a CT scan. Overall, 137 (26.2%) patients had an incidental finding on CT scan. The most common incidental finding was sinus opacification with an air fluid level (115/137, 83.9%). Thirty-five interventions were reported in children with incidental findings. Children 2 years old or younger were more likely to receive a prescription for antibiotics (relative risk [RR] = 2.66, 95% confidence interval [CI] = 1.08-6.51) and be referred to a specialist (RR = 10.26, 95% CI = 3.56-29.56) than older children. Incidental findings in minor head trauma are common. Clinicians should be prepared to address these findings if clinically indicated.

Severe injuries of the pancreatic head and duodenum in haemodynamically unstable patients are complex management. The purpose of this study is to report a case of complex pancreatic trauma induced by gunshot and managed with surgical approaches at three different times. Exploratory laparotomy was indicated after initial emergency room care, with findings of cloudy blood-tinged fluid and blood clots on the mesentery near the hepatic angle, on the region of the 2nd portion of the duodenum and at the pancreatic head. Gastroduodenopancreatectomy was performed with right hemicolectomy and the peritoneal cavity was temporarily closed by a vacuum peritoneostomy. Surgical reopening occurred on the fifth postoperative day, and the patient was subjected to single-loop reconstruction of the intestinal transit with telescoping pancreaticojejunal anastomosis, biliodigestive anastomosis with termino-lateral hepaticojejunal anastomosis with a Kehr drain and gastroenteroanastomosis in 2 planes. The terminal ileostomy was maintained. After 2 days, the patient was subjected to abdominal wall closure without complications, which required relaxing Gibson incisions and wound closure with polypropylene mesh placement in a pre-aponeurotic position closed with multiple stitches. The patient was discharged on the 40th post-trauma day without drains, with a functioning ileostomy and with a scheduled reconstruction of intestinal transit. In the presence of multiple associated injuries, hemodynamic instability and the need for an extensive surgical procedure such as duodenopancreatectomy, damage control surgery performed in stages as reported here enables the clinical stabilization of the patient for definitive treatment, achieving better survival results.

To report the clinical and radiological characteristics, management and outcomes of traumatic ascending aorta and aortic arch injuries. Historic cohort multicentre study including 17 major trauma patients with traumatic aortic injury from January 2000 to January 2011. The most common mechanism of blunt trauma was motor-vehicle crash (47%) followed by motorcycle crash (41%). Patients sustaining traumatic ascending aorta or aortic arch injuries presented a high proportion of myocardial contusion (41%); moderate or greater aortic valve regurgitation (12%); haemopericardium (35%); severe head injuries (65%) and spinal cord injury (23%). The 58.8% of the patients presented a high degree aortic injury (types III and IV). Expected in-hospital mortality was over 50% as defined by mean TRISS 59.7 (SD 38.6) and mean ISS 48.2 (SD 21.6) on admission. Observed in-hospital mortality was 53%. The cause of death was directly related to the ATAI in 45% of cases, head and abdominal injuries being the cause of death in the remaining 55% cases. Long-term survival was 46% at 1 year, 39% at 5 years, and 19% at 10 years. Traumatic aortic injuries of the ascending aorta/arch should be considered in any major thoracic trauma patient presenting cardiac tamponade, aortic valve regurgitation and/or myocardial contusion. These aortic injuries are also associated with a high incidence of neurological injuries, which can be just as lethal as the aortic injury, so treatment priorities should be modulated on an individual basis.

Epidemiology and pathogenesis of posttraumatic headache.

PubMed

Packard, R C

1999-02-01

This article presents an overview of the epidemiology and pathophysiology of posttraumatic headache. It reviews definitions of mild head injury (MHI), mild traumatic brain injury (MTBI), and concussion, and discusses the confusion that often occurs with these terms. Headache types and their pathophysiology are examined in detail. Just as the exact pathophysiology is unknown for migraine and other types of headache, the exact pathophysiology of headache after trauma is also still unknown in many cases. Possible connections between head or neck injuries and headache are reviewed, as well as hypothesized neurochemical changes that may occur in both migraine and traumatic brain injury (TBI). Psychological and legal factors are also considered.

Sports-related concussion has received increasing attention as a cause of short- and long-term neurologic symptoms among athletes. The King-Devick (K-D) test is based on measurement of the speed of rapid number naming (reading aloud single-digit numbers from 3 test cards), and captures impairment of eye movements, attention, language, and other correlates of suboptimal brain function. We investigated the K-D test as a potential rapid sideline screening for concussion in a cohort of boxers and mixed martial arts fighters. The K-D test was administered prefight and postfight. The Military Acute Concussion Evaluation (MACE) was administered as a more comprehensive but longer test for concussion. Differences in postfight K-D scores and changes in scores from prefight to postfight were compared for athletes with head trauma during the fight vs those without. Postfight K-D scores (n = 39 participants) were significantly higher (worse) for those with head trauma during the match (59.1 ± 7.4 vs 41.0 ± 6.7 seconds, p < 0.0001, Wilcoxon rank sum test). Those with loss of consciousness showed the greatest worsening from prefight to postfight. Worse postfight K-D scores (r(s) = -0.79, p = 0.0001) and greater worsening of scores (r(s) = 0.90, p < 0.0001) correlated well with postfight MACE scores. Worsening of K-D scores by ≥5 seconds was a distinguishing characteristic noted only among participants with head trauma. High levels of test-retest reliability were observed (intraclass correlation coefficient 0.97 [95% confidence interval 0.90-1.0]). The K-D test is an accurate and reliable method for identifying athletes with head trauma, and is a strong candidate rapid sideline screening test for concussion.

Objective: Sports-related concussion has received increasing attention as a cause of short- and long-term neurologic symptoms among athletes. The King-Devick (K-D) test is based on measurement of the speed of rapid number naming (reading aloud single-digit numbers from 3 test cards), and captures impairment of eye movements, attention, language, and other correlates of suboptimal brain function. We investigated the K-D test as a potential rapid sideline screening for concussion in a cohort of boxers and mixed martial arts fighters. Methods: The K-D test was administered prefight and postfight. The Military Acute Concussion Evaluation (MACE) was administered as a more comprehensive but longer test for concussion. Differences in postfight K-D scores and changes in scores from prefight to postfight were compared for athletes with head trauma during the fight vs those without. Results: Postfight K-D scores (n = 39 participants) were significantly higher (worse) for those with head trauma during the match (59.1 ± 7.4 vs 41.0 ± 6.7 seconds, p < 0.0001, Wilcoxon rank sum test). Those with loss of consciousness showed the greatest worsening from prefight to postfight. Worse postfight K-D scores (rs = −0.79, p = 0.0001) and greater worsening of scores (rs = 0.90, p < 0.0001) correlated well with postfight MACE scores. Worsening of K-D scores by ≥5 seconds was a distinguishing characteristic noted only among participants with head trauma. High levels of test-retest reliability were observed (intraclass correlation coefficient 0.97 [95% confidence interval 0.90–1.0]). Conclusions: The K-D test is an accurate and reliable method for identifying athletes with head trauma, and is a strong candidate rapid sideline screening test for concussion. PMID:21288984

Recurrent subdural hematoma secondary to headbanging: A case report.

"Headbanging" is the slang term used to denote violent shaking of one's head in time with the music. This abrupt flexion-extension movement of the head to rock music extremely rarely causes a subdural hematoma. A 24-year-old female was admitted to our department because of right sided partial seizure and acute or subacute subdural hematoma over the left cerebral convexity. She had no history of recent head trauma but performed headbanging at a punk rock concert at 3 days before admission. Since, she had a previous acute subdural hematoma on the same side after an accidental fall from a baby buggy when she was 11 months old, the present was recurrent subdural hematoma probably due to headbanging. Headbanging has the hazardous potential to cause a subdural hematoma.

Cycling Injuries in Southwest Colorado: A Comparison of Road vs Trail Riding Injury Patterns.

To describe the epidemiology of injuries sustained in cyclists and compare the injury patterns in road vs trail biking accidents. A retrospective chart review was performed of injured road and trail cyclists presenting to a rural mountain resort-based medical center during a 3-year study period. Of 304 patients, 70% were male, with 67% sustaining trail injuries and 33% sustaining road cycling injuries. There was a bimodal age distribution. Prehospital care was activated in 16% of patients. The most common injuries were lacerations and abrasions (64%), upper extremity fractures (26%), head injuries (9%), and thoracic trauma (6%). Head injury was more common in road- vs trail-related trauma (16% vs 6%; P = .005), whereas thoracic injury was more common in trail riders (7% vs 2%; P = .053). Head injury and lower extremit y fracture were the most common reasons for patient transfer. Patients with head injuries who did not use a helmet were more likely to require transfer to a neurosurgical unit (38% vs 17%; P = .296); however, this difference did not meet statistical significance. Lacerations and abrasions are the most common injuries sustained in cycling. Quantifying the role of protective extremity gear in reducing these injury patterns may be of interest for future studies. Protective helmet use may be important in reducing morbidity from cycling-related head trauma; however, more data are needed. Prehospital care providers responding to the injured trail cyclist should be equipped to manage laceration, fracture, head injury, and thoracic trauma in the field.

Pediatric radiological diagnostic procedures in cases of suspected child abuse.

PubMed

Erfurt, C; Hahn, G; Roesner, D; Schmidt, U

2011-03-01

Advanced and specialized radiological diagnostic procedures are essential in cases of clinically diagnosed injuries to the head, thorax, abdomen or extremities of a child, especially if there is no case history or if the reporting of an inadequate trauma suggests battered child syndrome. In particular, these diagnostic procedures should aim at detecting lesions of the central nervous system (CNS), so that the treatment can be immediately initiated. If the diagnostic imaging reveals findings typically associated with child abuse, accurate documentation constituting evidence, which will stand up in court, is required to prevent any further endangerment of the child's welfare.

In cases of suspected abusive head trauma, a thorough and systematic study of the cranium and its contents is essential, preferably using the best available methods for observing the brain and its coverings. Building upon recent developments in skull bone removal techniques in infant autopsies, we have assessed the use of two optical clearing agents (OCAs), glycerol and mannitol, on pediatric dura mater in an attempt to increase the transparency of this tissue and thereby enhance the post-mortem assessment of infant head injuries, particularly subdural hematomas. Extracorporeal testing revealed glycerol to be the more effective OCA. Therefore, in situ investigations were commenced using glycerol during 33 pediatric post-mortem examinations. An increase in the transparency of the dura was observed in 32 of the 33 cases, within 1 min of application of the OCA. In a 2 year old with cerebral palsy, only partial optical clearance of the dura was seen, most likely due to a significantly atrophic brain, prominent gelatinous leptomeninges, and abnormally thickened dura. This technique allowed for detection of minimal amounts of subdural bleeding over the convexities, before dissection of the dura, avoiding post-mortem blood spillage from artifactually disrupted bridging veins. Optical clearing of the dura aided in the evaluation of patterns of subdural hemorrhage in three cases of non-accidental head injury, three cases of peri-natal head injury and one case of overlaying, apparently resulting in minor crush injury to the head. We have demonstrated that glycerol is an effective and easy-to-use OCA to effect the readily reversible optical clearing of human infant calvarial dura at autopsy.

Idiopathic avascular necrosis of the femoral heads in five members of a Moroccan family.

Avascular necrosis (AVN) is idiopathic in about 40% of cases. The pathophysiology of avascular necrosis remains incompletely elucidated. Here, we report a case that underlines the role for inherited factors in AVN of the femoral heads. Idiopathic AVN of the femoral heads occurred in five members of the same family (a woman, her two paternal aunts, her male paternal cousin and her female paternal cousin) at a mean age of 42.4 years (range, 33-58 years). Standard pelvic radiographs showed Arlet and Ficat stage 4 AVN in three patients and stage 3 in two patients. None of the patients had a history of glucocorticoid therapy, alcohol abuse, or trauma. All five patients underwent investigations for a cause, including blood cell counts, a lipid profile, coagulation tests, testing for antinuclear antibodies, hemoglobin electrophoresis, ultrasonography of the abdomen, and standard radiographs of the long limb bones. The results were normal or negative, ruling out known hereditary causes of AVN such as sickle cell anemia and Gaucher disease. Many cases of familial AVN of the femoral head have been described in patients with sickle cell anemia or Gaucher disease. However, only five families with idiopathic familial AVN of the femoral heads have been reported (three in the US and two in Taiwan). All the patients in these families had isolated bilateral AVN of the femoral heads without AVN at other sites. Copyright © 2012. Published by Elsevier SAS.

Fatal carotid dissection after blunt head trauma.

2000-06-01

Occurrence of internal carotid artery injuries associated with skull base fracture has been reported. A. report a case of fatal intracranial carotid dissection related to petrous fracture involving the carotid canal. Identification of carotid lesions may be difficult and generally related to appearance of unexpected neurological deficit. Skull base fractures may be considered an indirect sign for detection of vascular injury. Patterns of the fracture are of paramount importance; routine CT scan may fail to detect basilar fractures and high definition fine-cut CT scan should be executed to carefully identify and evaluate fractures. Temporal and sphenoid bone fractures are common in head trauma and involvement of the course of the carotid artery is frequent. The involvement of the intracranial carotid artery course represents a direct risk factor for lesions of the petrous, lacerum and cavernous segments of the carotid artery. Early diagnosis of post-traumatic vascular injury may lead to prognosis improvement because of effectiveness of heparin anticoagulant therapy. Then vascular screening is recommendable in cases with complex fractures of the skull base and particularly fracturing along the course of the carotid artery. Magnetic resonance angiography may be considered the first line diagnostic tools for vascular screening. Angiography may be reserved for patients with a proven lesion or rapid neurological deterioration taking into account the possibility of interventional treatment.

Athletics, minor trauma, and pediatric arterial ischemic stroke.

PubMed

Sepelyak, Kathryn; Gailloud, Philippe; Jordan, Lori C

2010-05-01

Pediatric arterial ischemic stroke may occur as the result of trivial head or neck trauma sustained during a sports activity. We describe three cases of sports-related stroke in previously healthy school-age children and discuss acute and long-term stroke care. Possible mechanisms of sports-related stroke are addressed, as is evaluation for cause of stroke in children. In one of the reported cases, the child was found to have a vertebral artery dissection as the cause of his stroke, but no definitive cause of stroke was identified in the other two cases despite extensive evaluation. The advisability and timing of returning to athletic activities after stroke is also discussed. Many children with sports-related stroke are initially seen by a sports trainer, a pediatrician, or an ER physician. Thus, it is particularly important that these professionals are aware of the possibility of ischemic stroke occurring after even mild athletic injury. Childhood stroke may result from injuries sustained during athletic activities and should be considered when a child has acute focal neurologic signs.

Injuries of the Portal Vein in Patients With Blunt Abdominal Trauma

1993-01-01

Between January 1987 and September 1991, 68 severely traumatized patients underwent emergency laparotomy because of blunt abdominal trauma. Intraoperatively, 54.4% of the patients had a major injury to one organ, 23.5% had injuries to two organs, 16.2% had injuries to three organs and 5.9% to four or more organs. Additionally, in 11.8% of these cases (n = 8) a major vascular injury (portal vein n = 5, vena cava n = 2, mesenteric root n = 1) was found. Injuries to the portal vein were always associated with complete rupture of the pancreas, requiring distal pancreatic resection in four cases and a duodenum preserving resection of the head of the pancreas in one. In two of these patients the portal vein had to be reconstructed with a Goretex prosthetic graft. Mortality was 14.7% for the whole group (n = 68) and 0% for patients with additional portal venous injuries. PMID:8489966

Advanced and specialized radiological diagnostics are essential in the case of clinical suspicion of pediatric injuries to the head, thorax, abdomen, and extremities when there is no case history or when "battered child syndrome" is assumed on the basis of inadequate trauma. In particular, the aim of this sophisticated diagnostic procedure is the detection of lesions of the central nervous system (CNS) in order to initiate prompt medical treatment. If diagnostic imaging shows typical findings of child abuse, accurate documented evidence of the diagnostic results is required to prevent further endangerment of the child's welfare.

In this case report, we describe an unusual case of a patient with myoclonus only occurring during menses. A 41-year-old female, known to have neurological sequelae after a car accident 1 year earlier, presented with myoclonic movements of the right arm and hand only during menses. Brain magnetic resonance imaging is compatible with head trauma. Electromyography shows brief irregular bursts with a duration of about 20 ms. This appears to be the first description of myoclonus appearing only during menses. We suggest a cortical origin for myoclonus.

With increased computed tomography (CT) utilization, clinicians may simultaneously order head and neck CT scans, even when injury is suspected only in one region. We sought to determine: 1) the frequency of simultaneous ordering of a head CT scan when a neck CT scan is ordered; 2) the yields of simultaneously ordered head and neck CT scans for clinically significant injury (CSI); and 3) whether injury in one region is associated with a higher rate of injury in the other. This was a retrospective study of all adult patients who received neck CT scans (and simultaneously ordered head CT scans) as part of their blunt trauma evaluation at an urban level 1 trauma center in 2013. An expert panel determined CSI of head and neck injuries. We defined yield as number of patients with injury/number of patients who had a CT scan. Of 3223 patients who met inclusion criteria, 2888 (89.6%) had simultaneously ordered head and neck CT scans. CT yield for CSI in both the head and neck was 0.5% (95% confidence interval [CI] 0.3-0.8%), and the yield for any injury in both the head and neck was 1.4% (95% CI 1.0-1.8%). The yield for CSI in one region was higher when CSI was seen in the other region. The yield of CT for CSI in both the head and neck concomitantly is very low. When injury is seen in one region, there is higher likelihood of injury in the other. These findings argue against paired ordering of head and neck CT scans and suggest that CT scans should be ordered individually or when injury is detected in one region.

Computed Tomography (CT) scans are useful in the evaluation of trauma patients, but are costly and pose risks from ionizing radiation in children. Recent literature has demonstrated the utility of CT scan guidelines in the management of pediatric trauma. This study objective is to review our treatment of pediatric blunt trauma patients and evaluate CT utilization before and after CT-guideline implementation. Our Pediatric Level 2 Trauma Center (TC) implemented a CT scan practice guideline for pediatric trauma patients in March 2014. The guideline recommended for or against CT of the head and abdomen/pelvis utilizing published criteria from the Pediatric Emergency Care and Research Network (PECARN). There was no chest CT guideline. We reviewed all pediatric trauma patients for CT scans obtained during initial evaluation before and after guideline implementation, excluding inpatient scans. The Trauma Registry Database was queried to include all pediatric (age<15) trauma patients seen in our TC from 2010-2016, excluding penetrating mechanism and deaths in the TC. Scans were considered positive if organ injury was detected. Primary outcome was the proportion of patients undergoing CT and percent positive CTs. Secondary outcomes were hospital length of stay (LOS), readmissions, and mortality. Categorical and continuous variables were analyzed with Chi-square and Wilcoxon rank-sum tests, respectively. P<0.05 was considered significant. We identified 1934 patients: 1106 pre- and 828 post-guideline. Absolute reductions in head, chest, and abdomen/pelvis CT scans were 17.7%, 11.5%, and 18.8% respectively (p<0.001). Percent positive head CTs were equivalent, but percent positive chest and abdomen CT increased after implementation. Secondary outcomes were unchanged. Implementation of a pediatric CT guideline significantly decreases CT utilization, reducing the radiation exposure without a difference in outcome. Trauma centers treating pediatric patients should adopt similar guidelines to decrease unnecessary CT scans in children. Level IV, Therapeutic Study.

Although relatively uncommon, penetrating neck trauma has the potential for serious morbidity and an estimated mortality of up to 6%. The assessment and management of patients who have sustained a penetrating neck injury has historically been an issue surrounded by significant controversy. OBJECTIVES OF REVIEW: To assess recent evidence relating to the assessment and management of penetrating neck trauma, highlighting areas of controversy with an overall aim of formulating clinical guidelines according to a care pathway format. Structured, non-systematic review of recent medical literature. An electronic literature search was performed in May 2011. The Medline database was searched using the Medical Subject Headings terms 'neck injuries' and 'wounds, penetrating' in conjunction with the terms 'assessment' or 'management'. Embase was searched with the terms 'penetrating trauma' and 'neck injury', also in conjunction with the terms 'assessment' and 'management'. Results were limited to articles published in English from 1990 to the present day. Abstracts were reviewed by the first three authors to select full-text articles for further critical appraisal. The references and citation links of these articles were hand-searched to identify further articles of relevance. 147 relevant articles were identified by the electronic literature search, comprising case series, case reports and reviews. 33 were initially selected for further evaluation. Although controversy continues to surround the management of penetrating neck trauma, the role of selective non-operative management and the utility of CT angiography to investigate potential vascular injuries appears to be increasingly accepted. © 2011 Blackwell Publishing Ltd.

The world remains plagued by wars and terrorist attacks, and improvised explosive devices (IED) are the main weapons of our current enemies, causing almost two-thirds of all combat injuries. We wished to analyse the pattern of blast trauma on the modern battlefield and to compare it with combat gunshot injuries. Analysis of a consecutive series of combat trauma patients presenting to two Bulgarian combat surgical teams in Afghanistan over 11 months. Demographics, injury patterns and Injury Severity Scores (ISS) were compared between blast and gunshot-injured casualties using Fisher's Exact Test. The blast victims had significantly higher median ISS (20.54 vs 9.23) and higher proportion of ISS>16 (60% vs 33.92%, p=0.008) than gunshot cases. They also had more frequent involvement of three or more body regions (47.22% vs 3.58%, p<0.0001). A significantly higher frequency of head (27.27% vs 3.57%), facial (20% vs 0%) and extremities injuries (85.45% vs 42.86%) and burns (12.72% vs 0%) was noted among the victims of explosion (p<0.0001). Based on clinical examination and diagnostic imaging, primary blast injury was identified in 24/55 (43.6%), secondary blast injury in 37 blast cases (67.3%), tertiary in 15 (27.3%) and quaternary blast injury (all burns) in seven (12.72%). Our results corroborate the 'multidimensional' injury pattern of blast trauma. The complexity of the blast trauma demands a good knowledge and a special training of the military surgeons and hospital personnel before deployment.

Will Neuroimaging Reveal a Severe Intracranial Injury in This Adult With Minor Head Trauma?: The Rational Clinical Examination Systematic Review.

PubMed

Easter, Joshua S; Haukoos, Jason S; Meehan, William P; Novack, Victor; Edlow, Jonathan A

Adults with apparently minor head trauma (Glasgow Coma Scale [GCS] scores ≥13 who appear well on examination) may have severe intracranial injuries requiring prompt intervention. Findings from clinical examination can aid in determining which adults with minor trauma have severe intracranial injuries visible on computed tomography (CT). To assess systematically the accuracy of symptoms and signs in adults with minor head trauma in order to identify those with severe intracranial injuries. We performed a systematic search of MEDLINE (1966-2015) and the Cochrane Library to identify studies assessing the diagnosis of intracranial injuries. Studies were included that measured the performance of findings for identifying intracranial injury with a reference standard of neuroimaging or follow-up evaluation. Fourteen studies (range, 431-7955 patients) met inclusion criteria with patients having GCS scores between 13 and 15 and 50% or more older than 18 years. Three authors independently performed critical appraisal and data extraction. The prevalence of severe intracranial injury (requiring prompt intervention) among the 23,079 patients with minor head trauma was 7.1% (95% CI, 6.8%-7.4%) and the prevalence of injuries leading to death or requiring neurosurgical intervention was 0.9% (95% CI, 0.78%-1.0%). The presence of physical examination findings suggestive of skull fracture (likelihood ratio [LR], 16; 95% CI, 3.1-59; specificity, 99%), GCS score of 13 (LR, 4.9; 95% CI, 2.8-8.5; specificity, 97%), 2 or more vomiting episodes (LR, 3.6; 95% CI, 3.1-4.1; specificity, 92%), any decline in GCS score (LR range, 3.4-16; specificity range, 91%-99%;), and pedestrians struck by motor vehicles (LR range, 3.0-4.3; specificity range, 96%-97%) were associated with severe intracranial injury on CT. Among patients with apparent minor head trauma, the absence of any of the features of the Canadian CT Head Rule (≥65 years; ≥2 vomiting episodes, amnesia >30 minutes, pedestrian struck, ejected from vehicle, fall >1 m, suspected skull fracture, or GCS score <15 at 2 hours) had an LR of 0.04 (95% CI, 0-0.65), lowering the probability of severe injury to 0.31% (95% CI, 0%-4.7%). The absence of all the New Orleans Criteria findings (>60 years, intoxication, headache, vomiting, amnesia, seizure, or trauma above the clavicle) had an LR of 0.08 (95% CI, 0.01-0.84), lowering the probability of severe intracranial injury to 0.61% (95% CI, 0.08%-6.0%). Combinations of history and physical examination features in clinical decision rules can identify patients with minor head trauma at low risk of severe intracranial injuries. Certain findings, including signs of skull fracture, GCS score of 13, 2 or more vomiting episodes, decrease in GCS score, and pedestrians struck by motor vehicles, may help identify patients at increased risk of severe intracranial injuries.

Aimed to analyze demographical data and injury characteristics of patients who were injured in the Syrian Civil War (SCW) and to define differences in injury characteristics between adult and pediatric patients. Patients who were injured in the SCW and transferred to our emergency department were retrospectively analyzed in this study during the 15-month period between July 2013 and October 2014. During the study period, 1591 patients who were the victims of the SCW and admitted to our emergency department due to war injury enrolled in the study. Of these patients, 285 were children (18%). The median of the injury severity score was 16 (interquartile range [IQR]: 9-25) in all patients. The most frequent mechanism of injury was blunt trauma (899 cases, 55%), and the most frequently-injured region of the body was the head (676 cases, 42.5%). Head injury rates among the children's group were higher than those of the adult group (P < .001). In contrast, injury rates for the abdomen and extremities in the children's group were lower than those in the adult group (P < .001, P < .001). The majority of patients were adults, and the most frequent mechanism of injury was blunt trauma. Similarly, the children were substantially affected by war. Although the injury severity score values and mortality rates of the child and adult groups were similar, it was determined that the number of head injuries was higher, but the number of abdomen and extremity injuries was lower in the children's group than in the adult group.

This study examines the incidence and other epidemiological and medico-legal characteristics of child homicide in the territory of Belgrade, Republic of Serbia. We performed a retrospective analysis of all autopsies carried out at the Institute of Forensic Medicine in Belgrade during a 15 year period between 1991 and 2005, focusing on homicide cases of victims aged 0-14 years. These were then analyzed in terms of number of deaths, mortality rates, age, and sex of the victim, relation to the perpetrator, and cause of death and injury. Forty-six homicides were identified where the victims were aged 0-14 years. These included 24 girls and 22 boys. In 32 cases (69.6%) the perpetrator was one of the child's birth parents, more frequently the mother. Blunt head trauma was the most frequent cause of death, followed by exsanguination. In 9 cases (19.5%) there was evidence of physical abuse; 16 children died in the setting of multiple homicide and/or murder/suicide. In 4 cases (8.7%) there was evidence of neglect which contributed to the fatal outcome. There were 10 cases of neonaticide within the 46 homicides. There were, however, 49 further cases where bodies of newborn infants were discovered after having been disposed of in suspicious circumstances. Proportionally, the largest number of victims fell within the 1-4 years age group, with a slight preponderance of females, most of them killed at home by a close family member, usually the mother. Blunt head trauma was the single most frequent cause of death. Injury patterns consistent with child abuse were identified among 20% of the study group. Copyright © 2010 Elsevier Ltd.

Object We observed some cases of lung abscess (LA) in ICU patients suffering S.aureus ventilator-associated pneumonia (S.aureus-VAP). We aimed to assess which of the host and/or bacteria-related features are associated with LA. Methods We conducted a retrospective study from January 2009 to July 2013 in a trauma surgical ICU within a teaching hospital. All adult patients presenting with S.aureus-VAP were included. We compared two groups of patients according to the formation or not of LA concomitantly to S.aureus-VAP. Results Seventy-nine S.aureus-VAP patients, predominantly males (85%) of rather young age (mean [SD]: 35yr [21–64]) with severe trauma (initial Simplified Acute Score II = 42 [32–52]) related-ICU admission, were included. Among them, 10 (14%) developed LA. Patient’s characteristics significantly associated with LA development were: a younger age (p = 0.003), road traffic accidents admission (p = 0.017), head injury (p = 0.002), lower Glasgow Coma Scale (p = 0.009), blunt chest trauma (p = 0.01) pneumothorax (p = 0.01) and lung contusions (p = 0.002). No microbiological factors were significantly associated with LA formation. Abscesses were mostly bilateral, ≥5 cm of diameter and with a posterior location. Conclusions Our results do not favor a specific virulence of S.aureus, but rather highlight the role of multiple insults to the lung, promoting LA formation. Despite a similar severity score, patients with LA had more serious trauma, combining severe both chest and head insults. PMID:29261721

Paralabral rupture of the proximal biceps tendon from light weightlifting.

Rupture of the long head of the biceps is usually seen in older adults, in conjunction with rotator cuff tears or tenosynovitis secondary to chronic subacromial impingement; it is rarely seen as a result of trauma. We present the case of a young active patient who denied prodromal symptoms but ruptured the long head of the biceps brachii tendon (LHB) while performing 25-pound biceps curls. Upon examination, the patient was noted to have a readily apparent biceps defect and decreased strength. He was brought to the operating room, where open subpectoral tenodesis of the LHB was performed. At the 6-week follow-up evaluation, the patient had regained full range of motion. By 6 months, he had regained his previous strength. This case demonstrates an unusual presentation of a LHB rupture in a young healthy man with no prodromal symptoms.

Studies about head trauma are experimental or have a clinical or prognosis purpose. In this study, we used samples from human autopsies to answer common medical-legal questions.We studied 21 problem cases and 4 controls. Samples were obtained directly from the injured area, fixed in 10% formalin during 24 hours and then preserved in 70% ethanol. This procedure optimizes the immunohistochemical technique.The neurofilament antibody shows beaded axons since the first moment; over time, they increase their density and diameter as survival time also increases. These changes begin in the gray matter, 2 hours after trauma can be seen around vessels and in hemorrhagic areas. At 24 hours, beaded axons appear in the white mater, which finally loses its structure and cellular density.On the other hand, the β-amyloid precursor protein marker begins to be weakly seen 2 hours after injury. At 24 hours, a diffuse pattern can appear, suggesting primary traumatic injury. The marker reading keeps increasing until day 26, when a "Z" pattern appears in the white matter, suggesting secondary hypoxic injury.All these chronologic changes could be useful to approach the date of trauma. They let us to distinguish between long surviving cases from those whose death was immediate (within the first 30 minutes).

Mortality and morbidity from head trauma have been substantially reduced by improved prehospital care and aggressive diagnostic and therapeutic management. However, a substantial number of patients will require prolonged periods of hospitalization, intensive care, and ventilator support during their recovery, placing them at risk for infectious complications. Eighty-two such patients were reviewed during a 30-month period at a Level I trauma center. Forty-one patients (50%) developed at least one infectious complication. The most common source was respiratory, occurring in 34 patients relatively early (average, 3.2 days) in their hospital course. The severity of head injury and presence of coexisting thoracic trauma correlated statistically; administration of prophylactic antibiotics and corticosteroids did not in the development of infectious problems. Only three patients died as a result of sepsis, indicating that early recognition and prompt treatment may control the severity of infectious complications.

Process indicators have been widely used to monitor the way trauma care is provided. We aimed to analyze whether data from a hospital's severe trauma register could facilitate the evaluation of aspects of the initial management of severe injuries. Observational, retrospective population-based study. A working group of experts selected a set of trauma care process indicators relevant to some aspects of initial care, diagnosis, and treatment of severely injured patients. Four of the indicators referred to prehospital care and 5 to hospital care. We calculated the observed and expected compliance rates for all the indicators. A total of 1526 cases (44.4%) were analyzed for 2013; 1908 (55.6%) were analyzed for 2014. We were able to evaluate 3 of the 4 prehospital process indicators: endotracheal intubation in patients with a score of 8 on the Glasgow coma scale (GCS) (84% compliance), venous access established before hospital arrival (83.4%), and placement of a neck collar to immobilize the cervical spine (72.7%). Compliance for the hospital-phase indicators were as follows: performance of a computed tomography scan of the head within 60 minutes in cases with a GCS of 13 (5.3% compliance, craniotomy in candidate patients within 2 hours of diagnosis (65%), diagnostic examination for abdominal injuries within 60 minutes in patients with systolic blood pressure 90 mm Hg (89.3%), and therapeutic laparotomy or angiography within 4 hours of abdominal injury in candidate patients with systolic blood pressure 90 mm Hg (51.7%). Compliance was 69.9% for the last process indicator: surgical treatment of open fractures within 8 hours of an accident. Our findings show that a hospital trauma register provides data about care process indicators that can allow us to monitor the quality of care of severely injured patients.

Limited transthoracic echocardiogram (LTTE) has been introduced as a technique to direct resuscitation in intensive care unit (ICU) patients. Our hypothesis is that LTTE can provide meaningful information to guide therapy for hypotension in the trauma bay. LTTE was performed on hypotensive patients in the trauma bay. Views obtained included parasternal long and short, apical, and subxyphoid. Results were reported regarding contractility (good vs. poor), fluid status (flat inferior vena cava [hypovolemia] vs. fat inferior vena cava [euvolemia]), and pericardial effusion (present vs. absent). Need for surgery, ICU admission, Focused Assessment with Sonography for Trauma examination results, and change in therapy as a consequence of LTTE findings were examined. Data were collected prospectively to evaluate the utility of this test. A total of 148 LTTEs were performed in consecutive patients from January to December 2011. Mean age was 46 years. Admission diagnosis was 80% blunt trauma, 16% penetrating trauma, and 4% burn. Subxyphoid window was obtained in all patients. Parasternal and apical windows were obtained in 96.5% and 11%, respectively. Flat inferior vena cava was associated with an increased incidence of ICU admission (p < 0.0076) and therapeutic operation (p < 0.0001). Of the 148 patients, 27 (18%) had LTTE results indicating euvolemia. The diagnosis in these cases was head injury (n = 14), heart dysfunction (n = 5), spinal shock (n = 4), pulmonary embolism (n = 3), and stroke (n = 1). Of the patients, 121 had LTTE results indicating hypovolemia. Twenty-eight hypovolemic patients had a negative or inconclusive Focused Assessment with Sonography for Trauma examination finding (n = 18 penetrating, n = 10 blunt), with 60% having blood in the abdomen confirmed by surgical exploration or computed tomographic scan. Therapy was modified as a result of LTTE in 41% of cases. Strikingly, in patients older than 65 years, LTTE changed therapy in 96% of cases. LTTE is a useful tool to guide therapy in hypotensive patients in the trauma bay. Diagnostic study, level III.

The purpose of this study was to analyze the pathogenic mechanisms, clinical presentation, and surgical treatment of cervical disc herniation without external trauma. Between 2004 and 2008, 9 patients with cervical disc herniation and no antecedent history of trauma were diagnosed with cervical disc herniation and underwent surgical decompression. Pathogenic mechanisms, clinical presentation, surgical treatment, and prognosis were analyzed retrospectively. In 6 patients, herniation resulted from excessive neck motion rather than from external trauma. An injury from this source is termed an endogenous-lesioned injury. Patients exhibited neurologic symptoms of compression of the cervical spinal cord or nerve roots. In the other 3 patients, no clear cause for the herniation was recorded, but all patients had a desk job with long periods of head-down neck flexion posture. After surgery, all patients experienced a reduction in their symptoms and an uneventful recovery. Cervical disc herniation can occur in the absence of trauma. Surgical decompression is effective at reducing symptoms in these patients, similar to other patients with cervical disc herniation. Surgical treatment may be considered for this disorder when the herniation becomes symptomatic.

Early diagnosis of pancreatic trauma has always been challenging because of the lack of correlation between the initial clinical symptomatology, radiologic and laboratory findings, and the severity of the injury. Thanks to the improved performance of spiral CT scanning and magnetic resonance pancreatography, it is now often possible to make an early diagnosis of pancreatic contusion, to localize the site of the injury, and (most importantly) to identify injury to the main pancreatic duct which has major implications for the management of the case. When the trauma victim is unstable, radiologic work-up may be impossible and urgent laparotomy is required. Control of hemorrhage is the primary concern here and a damage control approach with packing may be appropriate; if the pancreatic head has been destroyed, a pancreaticoduodenectomy with delayed reconstruction may be required. If the trauma victim is stable, the treatment strategy will be governed by a variety of parameters--age, clinical condition, associated local anatomic findings (pancreatitis, injury to the duodenum or biliary tract), involvement of the pancreatic duct, and localization of the injury within the gland (to right or left of the mesenteric vessels).

Injury in childhood is a major cause of potentially preventable morbidity and mortality. In order to implement effective preventive strategies, epidemiological data on mechanisms of injury and outcome are essential. To assess the causation, severity of injury, morbidity and mortality of paediatric trauma admitted to a level 1 trauma intensive care unit (TICU). Children were defined as being <16 years of age. The study covered the 5-year period January 2008-December 2012. Eligible patients were identified from a prospective database maintained in the level 1 TICU at Inkosi Albert Luthuli Central Hospital, Durban, South Africa. Data extracted were referral source, mechanism of injury, age and gender distribution, injury severity score (ISS), anatomical distribution of injury and mortality. A total of 181 patients admitted during the study period accounted for 15.9% of all admissions. There were 84 females (46.4%) and 97 males (53.6%), with a median age of 7 years (interquartile range (IQR) 4-10). Sources of admission were directly from the scene in 38 cases (21.0%), from a primary healthcare facility in 47 (26.0%), from a regional hospital in 56 (31.0%) and from a tertiary facility in 40 (22.0%). Mortality rates according to location of transfer were regional hospital 8 deaths (30.8%), tertiary facility 7 (26.9%), primary health clinic 7 (26.9%), and from the scene 4 (15.4%). Mechanisms of injury were pedestrian-motor vehicle collision (PMVC) in 105 cases (58.0%), motor vehicle passenger in 38 (21.0%), non-vehicular blunt trauma in 18 (10.0%), gunshot wounds (GSWs) in 12 (6.6%), stab wounds in 6 (3.3%), bull goring in 1 (0.5%) and bicycle accident 1 (0.5%). The median ISS for all admissions was 25 (IQR 16-38). ISSs were >25 in 98 patients (54.1%), 16-25 in 51 (28.2%), 9-15 in 9 (4.9%) and <9 in 13 (7.2%); 61.9% of patients had head injuries, 48.1% injuries to the extremities, 41.4% abdominal trauma, 40.3% thoracic trauma, 20.4% external soft-tissue trauma, 9.9% cervical injury and 9.4% facial trauma. There were 26 deaths (14.4%), of which PMVCs accounted for 16 (61.5%), motor vehicle passengers for 7 (26.9%), blunt trauma for 2 (7.7%) and GSWs for 1 (3.8%). The majority of deaths (92%) were of patients with an ISS>25. Of the 26 patients who died, 88.4% had a head injury, 46.2% an extremity injury, 38.5% an external injury, 34.6% abdominal or chest injuries, 19.2% neck injury and 11.5% facial injury. Motor vehicle-related injuries, especially PMVCs, dominate severe paediatric trauma and there is an urgent need for more road traffic education and stringent measures to decrease the incidence and associated morbidity and mortality.

This study was performed on 200 patients with a prospective method, between July and October 1998. The aim of the study was to analyze the patients who were admitted directly or referred from another hospital, if they were suitable with the transfer criteria to a level I trauma center. One hundred and seven patients (53.5%) were admitted without ambulance and 93 patients (46.5%) by ambulance to our center. 34% of those patients applied directly and 66% of them were sent from other hospitals. Private ambulances consisted 70%, and 30% the belonged to the national health service. Only 26% of the ambulances had doctor as staff. The most common trauma etiologies were: traffic accidents (42.5%), falling from a height (37.5%) and assaults (11.5%). The mean Glasgow coma score (GCS) of the patients was calculated as 13.9 and mean revised trauma score was 11.7. The Glasgow coma score, revised trauma score and appropriateness to the transfer criteria of the American College of Surgeons were statistically analyzed according to the Fischer Exact test. The results revealed that 96% of the patients with RTS, 86% of the patients with GCS and 60% of the patients with ACS were not appropriate to the transfer criteria to a level I trauma center. In conclusion; we believe that GCS will predict better results in the triage of trauma patients with head trauma in our country.

Despite improvements in prevention and rescue, mortality rates after severe blunt trauma continue to be a problem. The present study analyses mortality patterns in a representative blunt trauma population, specifically the influence of demographic, injury pattern, location and timing of death. Patients that died between 1 January 2004 and 31 December 2005 were subjected to a standardised autopsy. death from blunt trauma due to road traffic injuries (Injury Severity Score ≥ 16), patients from a defined geographical area and death on scene or in hospital. suicide, homicide, penetrating trauma and monotrauma including isolated head injury. Statistical analyses included Student's t test (parametric), Mann-Whitney U test (nonparametric) or Chi-square test. A total of 277 consecutive injured patients were included in this study (mean age 46.1 ± 23 years; 67.5% males), 40.5% of which had an ISS of 75. A unimodal distribution of mortality was observed in blunt trauma patients. The most frequently injured body regions with the highest severity were the head (38.6%), chest (26.7%), or both head and chest (11.0%). The cumulative analysis of mortality showed that several factors, such as injury pattern and regional location of collisions, also affected the pattern of mortality. The majority of patients died on scene from severe head and thoracic injuries. A homogenous distribution of death was observed after an initial peak of death on scene. Moreover, several factors such as injury pattern and regional location of collisions may also affect the pattern of mortality.

This study investigated characteristics and trends of hospitalized abuse-related traumatic brain injuries (TBI) treated at a large pediatric medical center in Wuhan, China during the past 10 years. De-identified hospital discharge data for patients 0–4 years old hospitalized at the Wuhan Medical Care Center for Women and Children were analyzed, and ICD-10 codes were used to identify cases of TBI. Medical notes provided by doctors in the medical record were used to identify TBI cases in which suspected child abuse was the cause. From 2002 to 2011, 3,061 pediatric TBI patients were hospitalized and 4.6% (140) of these cases were suspected child abuse-related. The majority of suspected child abuse cases involved children younger than 1 year of age (68.6%) and usually affected males (63.6%). Children with non-Abusive Head Trauma (AHT) were more likely to have full recovery outcome (68.4%, 95% CI: 66.6%–70.0%) than children with suspected AHT (44.3%, 95% CI: 36.1%–52.5%). The proportion of all childhood TBI attributable to abuse did not appear to have increased in the 10-year period at this medical center. This is the first comprehensive study highlighting the important role of suspected child abuse in causing TBIs among Chinese children. Child abuse as a major cause of TBIs among infants in China should be studied further, and there should be greater awareness of this important social and medical problem in China. PMID:23202840

To assess the accuracy of an International Classification of Diseases (ICD) code-based operational case definition for abusive head trauma (AHT). Subjects were children <5 years of age evaluated for AHT by a hospital-based Child Protection Team (CPT) at a tertiary care paediatric hospital with a completely electronic medical record (EMR) system. Subjects were designated as non-AHT traumatic brain injury (TBI) or AHT based on whether the CPT determined that the injuries were due to AHT. The sensitivity and specificity of the ICD-based definition were calculated. There were 223 children evaluated for AHT: 117 AHT and 106 non-AHT TBI. The sensitivity and specificity of the ICD-based operational case definition were 92% (95% CI 85.8 to 96.2) and 96% (95% CI 92.3 to 99.7), respectively. All errors in sensitivity and three of the four specificity errors were due to coder error; one specificity error was a physician error. In a paediatric tertiary care hospital with an EMR system, the accuracy of an ICD-based case definition for AHT was high. Additional studies are needed to assess the accuracy of this definition in all types of hospitals in which children with AHT are cared for. Published by the BMJ Publishing Group Limited.

[Management of patients with simple cervical distortions].

PubMed

Foletti, G; Regli, F

1995-11-11

Common distortion of the cervical spine without evidence of neurological or osteoligamentary damage is a frequent consequence of indirect head and neck trauma. The mechanism of the injury (called "whiplash", "coup de lapin", or "Schleudertrauma") does not imply direct trauma to the head or neck. In the acute phase, common distortion of the cervical spine requires treatment. Rapid management may avoid or considerably reduce the chronic pain syndrome with the characteristic chronic tension-like headache. The chronic pain and the numerous associated functional disorders are not well understood: certain factors favour central and peripheral dysfunction and others emphasize the importance of extra-trauma phenomena. In our opinion, extra-trauma phenomena would explain the invalidating nature of pain in a small number of patients. Management of these chronic patients requires a multidisciplinary approach aimed at helping the patient overcome the inconveniences of this condition.

Although uncommon, fractures of the os odontoideum are known to occur in children under 7 years old, following acute trauma. We report a case of chronic subluxation of the os odontoideum resulting in cervical myelopathy in a child with Beare-Stevenson cutis gyrata syndrome after surgery to the head and neck. The patient was initially put in a Halo vest, following which occipital cervical fusion was performed. Subluxations and fractures at the odontoid synchondrosis are rare but should be anticipated in young children with risk factors for instability of the cervical spine.

Long Term Survivorship of a Severely Notched Femoral Stem after Replacing the Fractured Ceramic head with a Cobalt-Chromium Head.

Although ceramic head fracture occurs infrequently today, in the event of a fracture, the resulting revision surgery can prove very challenging, since the ceramic particles lodge into the surrounding soft tissue and can cause rapid implant failure. A case of long term survivorship of a severed notched femoral stem after replacing the fractured femoral head with a cobalt-chromium one is reported in a 40-year old woman with hip dysplasia who underwent an uncomplicated total hip arthroplasty. The incident of ceramic femoral head fracture occurred 14 months postoperatively without reporting any significant trauma. Intraoperative findings at revision were a multifragmented femoral head and a damaged polyethylene insert along with diffuse metallosis and excessive wear of the cone of the stem. Both the stem and the acetabular component were stable. After removal of ceramic fragments, metallotic tissue excision and careful lavage of the joint, the inlay was replaced by a similar one and a cobalt-chromium femoral head was placed to the existing notched taper of the firmly incorporated stem. At the 13 th year follow up examination, the patient had no pain, used no walking aids, and had normal activity with no signs of wearing or loosening in the plain x-rays. Despite current recommendations of using ceramic femoral heads in cases of fracture or to revise the severely damaged stems we were able to provide a long term survivorship up to 13 years postoperatively of a cobalt-chromium femoral head applied to a severe damaged stem.

Gunshot wounds (GSWs) to the face are an infrequent occurrence outside of a war zone. However, when they occur, they constitute a significant reconstructive challenge. We present our 10-year experience at an urban level I trauma center to define the patterns of injury, assess the morbidity and mortality, and estimate the cost to the health care system. A retrospective review was performed on all patients admitted to Harbor-UCLA Medical Center with GSWs to the head and neck region between January 1997 and January 2007. Those who had sustained GSWs to the face requiring operative intervention were closely reviewed. Between 1997 and 2007, a total of 702 patients were admitted to the Harbor UCLA Emergency Department having sustained GSWs to the head and neck region, of which 501 patients survived. Of the survivors, 28 patients (26 male, 2 female) sustained GSWs to their face requiring operative intervention. The mean age of these patients was 28 (±8.3) years. They generally presented within a few hours of the injury, but 1 individual arrived over 24 hours later. Low-velocity single gunshots (from handguns) were predominantly involved, with facial fractures occurring in all cases. Fractures were of a localized shattering type without the major displacement of bony complexes seen in motor vehicle accidents. Most required wound debridement and fracture fixation. A few patients (14.2%) underwent free tissue transfer for reconstruction (3 fibular flaps, 1 TRAM). Tracheostomy was performed in 35.7% of patients. Mean length of hospital stay was 8.3 (±7.1) days, with 50% of cases requiring admission to the intensive care unit. Mean length of intensive care unit stay was 5.2 (±5.7) days. The average cost per patient exceeded $100,000.

Mixed martial arts (MMA) is a full combative sport with a recent global increase in popularity despite significant scrutiny from medical associations. To date, the empirical research of the risk of head injuries associated with this sport is limited. Youth and amateur participation is growing, warranting investigation into the burden and mechanism of injuries associated with this sport. (1) To determine the incidence, risk factors, and characteristics of knockouts (KOs) and technical knockouts (TKOs) from repetitive strikes in professional MMA; and (2) to identify the mechanisms of head trauma and the situational factors that lead to KOs and TKOs secondary to repetitive strikes through video analysis. Descriptive epidemiology study. Competition data and video records for all KOs and TKOs from numbered Ultimate Fighting Championship MMA events (n = 844) between 2006 to 2012. Analyses included (1) multivariate logistic regression to investigate factors associated with an increased risk of sustaining a KO or TKO secondary to repetitive strikes and (2) video analysis of all KOs and TKOs secondary to repetitive strikes with descriptive statistics. During the study period, the KO rate was 6.4 per 100 athlete-exposures (AEs) (12.7% of matches), and the rate of TKOs secondary to repetitive strikes was 9.5 per 100 AEs (19.1% of matches), for a combined incidence of match-ending head trauma of 15.9 per 100 AEs (31.9% of matches). Logistic regression identified that weight class, earlier time in a round, earlier round in a match, and older age were risk factors for both KOs and TKOs secondary to repetitive strikes. Match significance and previously sustained KOs or TKOs were also risk factors for KOs. Video analysis identified that all KOs were the result of direct impact to the head, most frequently a strike to the mandibular region (53.9%). The average time between the KO-strike and match stoppage was 3.5 seconds (range, 0-20 seconds), with losers sustaining an average of 2.6 additional strikes (range, 0-20 strikes) to the head. For TKOs secondary to strikes, in the 30-second interval immediately preceding match stoppage, losers sustained, on average, 18.5 strikes (range, 5-46 strikes), with 92.3% of these being strikes to the head. Rates of KOs and TKOs in MMA are higher than previously reported rates in other combative and contact sports. Public health authorities and physicians should be cognizant of the rates and mechanisms of head trauma. Preventive measures to lessen the risks of head trauma for those who elect to participate in MMA are described. © 2014 The Author(s).

Trauma Imaging: A Literature Review.

To inform radiologic technologists about which imaging modalities and examinations are best suited for evaluating specific anatomical structures in patients who have sustained a traumatic injury. Two scholarly research databases were searched to identify articles focused on trauma imaging of the head, cervical spine, thorax, abdomen, and pelvis. Articles focused on trauma diagnosis were excluded. Thirty-two articles were selected for analysis. Physical examination and plain-film radiographs typically are used to assess nasal bone fracures. Computed tomography (CT) can be used to assess zygomaticomaxillary complex, mandibular, and temporal bone fractures. Traumatic brain injuries are difficult to assess, and broad classifications are used. Depending on the severity of cervical spine trauma, plain-film radiographs or CT imaging is adequate, with magnetic resonance imaging used as a means for further evaluation. Trauma to the thorax typically is assessed with radiography and CT, and CT is recommended for assesment of abdominal and pelvic trauma. The literature was consistent regarding which examinations to perform to best evaluate suspected injuries to the chest, abdomen, and pelvis. The need for, and correct use of, imaging in evaluating trauma to the head and cervical spine is more controversial. Despite the need for additional research, emergency department care providers should be familiar with the structures most commonly injured during trauma and the role of medical imaging for diagnosis.

Aim: The aim of this study was to investigate epidemiological features of maxillofacial fractures within trauma patients who had head and neck computed tomography (CT) scan at the Mulago National referral hospital. Methods: CT scan records of trauma patients who had head scans at the Department of Radiology over 1-year period were accessed. Data collected included sociodemographic factors, type and etiology of injury, and concomitant maxillofacial injuries. Results: A total of 1330 trauma patients underwent head and neck CT scan in the 1-year study period. Out of these, 130 were excluded due to incomplete or unclear records and no evidence of injury. Of the remaining 1200, 32% (387) had maxillofacial fractures. The median age of the patients with maxillofacial fractures was 28 (range = 18–80) years and 18–27 age group was most common at 47.5%. Road traffic accidents constituted 49.1% of fractures. The single most affected isolated bone was the frontal bone (23%). The number of maxillofacial bones fractured was predicted by age group (df = 3 F = 5.358, P = 0.001), association with other fractures (df = 1 F = 5.317, P = 0.03). Conclusions: Good matched case–control prospective studies are needed to enable us tease out the finer difference in the circumstances and pattern of injury if we are to design appropriate preventive measures.

Mild head trauma is a frequent complaint in Pediatric Emergency Departments. Several guidelines have been published in the last few years. However, significant variability can be appreciated in terms of the demand for image tests. The aim of this study is to determine the level of compliance with PECARN and AEP guidelines in the management of patients younger than 24 months old in four different hospitals. A multicenter retrospective study was conducted on patients presenting with mild head trauma between October 1st, 2011 and March 31st, 2013 in the Emergency Departments of four hospitals. In the analysis of the results obtained, only one of the four hospitals complied with the AEP guidelines in more than 50% of the patients. The other three hospitals had a level of compliance lower than 50%. Management was more suitable according to PECARN guidelines, with 3 of the 4 hospitals having a level of compliance greater than 50%. However, the best compliance achieved by a hospital was only of 70%. The study shows that the level of compliance with guidelines for management of mild head trauma in patients younger than 24 months old is low. Copyright © 2014 Asociación Española de Pediatría.

To determine computerized tomography (CT) use and prevalence of traumatic intracranial hemorrhage (ICH) in children with and without congenital and acquired bleeding disorders. We compared CT use and ICH prevalence in children with and without bleeding disorders in a multicenter cohort study of 43 904 children <18 years old with blunt head trauma evaluated in 25 emergency departments. A total of 230 children had bleeding disorders; all had Glasgow Coma Scale (GCS) scores of 14 to 15. These children had higher CT rates than children without bleeding disorders and GCS scores of 14 to 15 (risk ratio, 2.29; 95% CI, 2.15 to 2.44). Of the children who underwent imaging with CT, 2 of 186 children with bleeding disorders had ICH (1.1%; 95% CI, 0.1 to 3.8) , compared with 655 of 14 969 children without bleeding disorders (4.4%; 95% CI, 4.1-4.7; rate ratio, 0.25; 95% CI, 0.06 to 0.98). Both children with bleeding disorders and ICHs had symptoms; none of the children required neurosurgery. In children with head trauma, CTs are obtained twice as often in children with bleeding disorders, although ICHs occurred in only 1.1%, and these patients had symptoms. Routine CT imaging after head trauma may not be required in children without symptoms who have congenital and acquired bleeding disorders. Copyright © 2011 Mosby, Inc. All rights reserved.

Abusive head trauma is the leading cause of death from physical abuse. Missing the diagnosis of abusive head trauma, particularly in its mild form, is common and contributes to increased morbidity and mortality. Serum biomarkers may have potential as quantitative point-of-care screening tools to alert physicians to the possibility of intracranial hemorrhage. To identify and validate a set of biomarkers that could be the basis of a multivariable model to identify intracranial hemorrhage in well-appearing infants using the Ziplex System. Binary logistic regression was used to develop a multivariable model incorporating 3 serum biomarkers (matrix metallopeptidase-9, neuron-specific enolase, and vascular cellular adhesion molecule-1) and 1 clinical variable (total hemoglobin). The model was then prospectively validated. Multiplex biomarker measurements were performed using Flow-Thru microarray technology on the Ziplex System, which has potential as a point-of-care system. The model was tested at 3 pediatric emergency departments in level I pediatric trauma centers (Children's Hospital of Pittsburgh of University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania; Primary Children's Hospital, Salt Lake City, Utah; and Lurie Children's Hospital, Chicago, Illinois) among well-appearing infants who presented for care owing to symptoms that placed them at increased risk of abusive head trauma. The study took place from November 2006 to April 2014 at Children's Hospital of Pittsburgh, June 2010 to August 2013 at Primary Children's Hospital, and January 2011 to August 2013 at Lurie Children's Hospital. A mathematical model that can predict acute intracranial hemorrhage in infants at increased risk of abusive head trauma. The multivariable model, Biomarkers for Infant Brain Injury Score, was applied prospectively to 599 patients. The mean (SD) age was 4.7 (3.1) months. Fifty-two percent were boys, 78% were white, and 8% were Hispanic. At a cutoff of 0.182, the model was 89.3% sensitive (95% CI, 87.7-90.4) and 48.0% specific (95% CI, 47.3-48.9) for acute intracranial hemorrhage. Positive and negative predictive values were 21.3% and 95.6%, respectively. The model was neither sensitive nor specific for atraumatic brain abnormalities, isolated skull fractures, or chronic intracranial hemorrhage. The Biomarkers for Infant Brain Injury Score, a multivariable model using 3 serum biomarker concentrations and serum hemoglobin, can identify infants with acute intracranial hemorrhage. Accurate and timely identification of intracranial hemorrhage in infants without a history of trauma in whom trauma may not be part of the differential diagnosis has the potential to decrease morbidity and mortality from abusive head trauma.

Concussions typically resolve within several days, but in a few cases the symptoms last for a month or longer and are termed persistent postconcussive symptoms (PPCS). These persisting symptoms may also be associated with more serious brain trauma similar to subdural hematoma (SDH). The objective of this study was to investigate the head dynamic and brain tissue responses of injury reconstructions resulting in concussion, PPCS, and SDH. Reconstruction cases were obtained from sports medicine clinics and hospitals. All subjects received a direct blow to the head resulting in symptoms. Those symptoms that resolved in 9 days or fewer were defined as concussions (n = 3). Those with symptoms lasting longer than 18 months were defined as PPCS (n = 3), and 3 patients presented with SDHs (n = 3). A Hybrid III headform was used in reconstruction to obtain linear and rotational accelerations of the head. These dynamic response data were then input into the University College Dublin Brain Trauma Model to calculate maximum principal strain and von Mises stress. A Kruskal-Wallis test followed by Tukey post hoc tests were used to compare head dynamic and brain tissue responses between injury groups. Statistical significance was set at p < 0.05. A significant difference was identified for peak resultant linear and rotational acceleration between injury groups. Post hoc analyses revealed the SDH group had higher linear and rotational acceleration responses (316 g and 23,181 rad/sec(2), respectively) than the concussion group (149 g and 8111 rad/sec(2), respectively; p < 0.05). No significant differences were found between groups for either brain tissue measures of maximum principal strain or von Mises stress. The reconstruction of accidents resulting in a concussion with transient symptoms (low severity) and SDHs revealed a positive relationship between an increase in head dynamic response and the risk for more serious brain injury. This type of relationship was not found for brain tissue stress and strain results derived by finite element analysis. Future research should be undertaken using a larger sample size to confirm these initial findings. Understanding the relationship between the head dynamic and brain tissue response and the nature of the injury provides important information for developing strategies for injury prevention.

Several retrospective clinical studies and recent prospective animal models demonstrate improved outcomes with beta-blocker administration after isolated blunt head injury. However, no investigations to date have examined the influence of race on the potential therapeutic effectiveness of these medications. Our hypothesis was that mortality benefits associated with beta-blocker exposure after isolated blunt head injury varies based on ethnicity. The trauma registry and the surgical intensive care unit (ICU) databases of an academic Level I trauma center were used to identify all patients sustaining blunt head injury requiring ICU admission from July 1998 to December 2009. Patients sustaining major associated extracranial injuries (Abbreviated Injury Scale [AIS] score ≥ 3 in any body region) were excluded. Patient demographics, injury profile, Injury Severity Score, and beta-blocker exposure were abstracted. The primary outcome evaluated was in-hospital mortality stratified by ethnicity. During the 11-year study period, 3,750 patients were admitted to the Los Angeles County + University of Southern California Medical Center trauma ICU because of blunt trauma. Of these, 65% (n = 2,446) had an "isolated" head injury. When stratified by race, most patients were Hispanics (60%), followed by Whites (21%), Asians (11%), and African Americans (8%). After adjusting for confounding variables with multivariate regression, only those of Asian and Hispanic descent demonstrated significantly improved outcomes associated with beta-blocker administration. Our results indicate that beta-blockade after traumatic brain injury may not benefit all races equally. Further prospective research is necessary to assess this discrepancy in treatment benefit and explore other possible therapeutic interventions.

Vertebral Artery Dissection Causing Stroke After Trampoline Use.

2015-11-01

The aim of this study was to report a case of a 4-year-old boy who had been playing on the trampoline and presented to the emergency department (ED) with vomiting and ataxia, and had a vertebral artery dissection with subsequent posterior circulation infarcts. This study is a chart review. The patient presented to the emergency department with a 4-day history of vomiting and gait unsteadiness. A computed tomography scan of his head revealed multiple left cerebellar infarcts. Subsequent magnetic resonance imaging/magnetic resonance angiogram of his head and neck demonstrated multiple infarcts involving the left cerebellum, bilateral thalami, and left occipital lobe. A computed tomography angiogram confirmed the presence of a left vertebral artery dissection. Vertebral artery dissection is a relatively common cause of stroke in the pediatric age group. Trampoline use has been associated with significant risk of injury to the head and neck. Patients who are small and/or young are most at risk. In this case, minor trauma secondary to trampoline use could be a possible mechanism for vertebral artery dissection and subsequent strokes. The association in this case warrants careful consideration because trampoline use could pose a significant risk to pediatric users.

In March of 2008, an expert panel was convened at the Centers for Disease Control and Prevention to develop code-based case definitions for abusive head trauma (AHT) in children under 5 years of age based on the International Classification of Diseases, 10th Revision (ICD-10) nature and cause of injury codes. This study presents the operational case definition and applies it to US death data. National Center for Health Statistics National Vital Statistics System data on multiple cause-of-death from 2003 to 2007 were examined. Inspection of records with at least one ICD-10 injury/disease code and at least one ICD-10 cause code from the AHT case definition resulted in the identification of 780 fatal AHT cases, with 699 classified as definite/presumptive AHT and 81 classified as probable AHT. The fatal AHT rate was highest among children age <1 year with a peak in incidence that occurred at 1-2 months of age. Fatal AHT incidence rates were higher for men than women and were higher for non-Hispanic African-Americans compared to other racial/ethnic groups. Fatal AHT incidence was relatively constant across seasons. This report demonstrates that the definition can help to identify population subgroups at higher risk for AHT defined by year and month of death, age, sex and race/ethnicity. This type of definition may be useful for various epidemiological applications including research and surveillance. These activities can in turn inform further development of prevention activities, including educating parents about the dangers of shaking and strategies for managing infant crying.

This systematic review explored the indications, efficacy, and complications of hip arthroscopy in the setting of trauma. Databases (PubMed, Medline, Embase, and Web of Science) were searched from database inception to March 2015 for studies using hip arthroscopy in trauma treatment. Systematic screening of eligible studies was undertaken in duplicate. The inclusion criteria included studies pertaining to arthroscopic intervention of all traumatic hip injuries. Abstracted data were organized in table format with descriptive statistics presented. From an initial search yield of 2,809 studies, 32 studies (25 case reports and 7 case series) satisfied the criteria for inclusion. A total of 144 patients (age range, 10 to 53 years) underwent hip arthroscopy for 6 indications associated with trauma: 8 patients for bullet extraction, 6 for femoral head fixation, 82 for loose body removal, 6 for acetabular fracture fixation, 20 for labral intervention, and 23 for ligamentum teres debridement. Patients were followed up postoperatively for a mean of 2.9 years (range, 8 days to 16 years). Successful surgery was achieved in 96% of patients. The rate of major complications (i.e., pulmonary embolism and abdominal compartment syndrome) was 1.4% (2 of 144); avascular necrosis, 1.4% (2 of 144); and nerve palsy, 0.7% (1 of 144). Hip arthroscopy appears effective and safe in the setting of trauma. These data should be interpreted with caution because of the low-quality evidence of the included studies. Surgeons should be aware of the potential complications such as abdominal compartment syndrome and thromboembolic events when performing hip arthroscopy in the setting of trauma.

Background and Aims: Restriction of head and neck movements prevents the alignment of the oral, pharyngeal, and laryngeal axes and increases the incidence of difficult tracheal intubation in patients with cervical spine fractures. Video laryngoscopes have gained an important role in the management of difficult intubation, especially in situations with limited head and neck movements. This study compares the success of intubation using Macintosh laryngoscope assisted Bonfils® fiberscope (ML-BF) with TruviewPCD video laryngoscope (TV) in patients with simulated restricted head and neck movements. Material and Methods: One hundred and fifty-two patients satisfying the inclusion criteria were randomly allocated to two groups of 76 each. Patients were made to lie supine on the table without a pillow and a soft collar was used to restrict head and neck movements. After a standardized premedication-induction sequence, tracheal intubation was done either with ML-BF or TV. Success of intubation, time taken for successful intubation, hemodynamic changes, airway trauma, and postoperative oropharyngeal morbidity were noted. Results: Intubation was successful in all the 76 patients in direct laryngoscopy-Bonfils fiberscope group and 75 out of 76 patients in TV group within the specified time (90 s). The median time taken for successful intubation with TV and ML-BF were 44 (range 26–80) s and 49 (range 28–83) s, respectively. Hemodynamic changes, airway trauma, and postoperative oropharyngeal morbidity were similar in both groups. Conclusion: Both TV and ML-BF are equally effective for successful tracheal intubation in patients with simulated restricted head and neck movements. In cases of difficult laryngeal visualization with routine Macintosh laryngoscope, Bonfils can be used as an adjunct to achieve successful intubation in the same laryngoscopy attempt. PMID:28413282

Pediatric head trauma is a common occurrence. There is mounting evidence that even patients with minor head injury require limits on school activities and/or removal from sports and play to help speed recovery and limit morbidity. The objective of this study was to determine whether discharge instructions given to children who had sustained head injuries included information regarding activity restrictions, activity time constraints, and/or specifics of follow-up care. This was a retrospective chart review of patients aged 2 to 18 years evaluated and treated for head injury during a 4-month period at a level I trauma center (volume ∼23,000 pediatric patients per year). Included were those children seen, evaluated, and diagnosed with any of the following: mild head injury, concussion, minor head trauma, or mild traumatic brain injury (mTBI). Subjects were excluded if there was a positive acute head injury computed tomography finding (other than findings of a simple linear skull fracture) or if the subject required admission. Among the 204 patients meeting eligibility, 95.1% received instruction to follow up with a physician, 82.8% received anticipatory guidance regarding expected symptoms, 15.2% received specific restriction time from sports, and 21.5% were removed from sports. Of these patients, 113 patients were determined "likely" to have sustained an mTBI. Patients with sports-related mTBI received return-to-sports restrictions (χ2 = 11.225, P < 0.008) and to remove the child from play (χ2 = 9.781, P < 0.004) as discharge instructions significantly more than did patients with motor vehicle accident or other mechanisms of injury. Children sustaining head injury were inadequately instructed to restrict athletic activities upon discharge. This is particularly true for patients who sustain an mTBI from non-sports-related activity.

Despite the higher theoretical risk of traumatic intracranial hemorrhage (ICH) in anticoagulated patients with mild head injury, the value of sequential head CT scans to identify bleeding remains controversial. This study evaluated the utility of 2 sequential CT scans at a 48-hour interval (CT1 and CT2) in patients with mild head trauma (Glasgow Coma Scale 13-15) taking oral anticoagulants. We retrospectively evaluated the clinical records of all patients on chronic anticoagulation treatment admitted to the emergency department for mild head injury. A total of 344 patients were included, and 337 (97.9%) had a negative CT1. CT2 was performed on 284 of the 337 patients with a negative CT1 and was positive in 4 patients (1.4%), but none of the patients developed concomitant neurologic worsening or required neurosurgery. Systematic routine use of a second CT scan in mild head trauma in patients taking anticoagulants is expensive and clinically unnecessary.

2012-01-01

Background Sports-related head trauma is common but still there is no established laboratory test used in the diagnostics of minimal or mild traumatic brain injuries. Further the effects of recurrent head trauma on brain injury markers are unknown. The purpose of this study was to investigate the relationship between Olympic (amateur) boxing and cerebrospinal fluid (CSF) brain injury biomarkers. Methods The study was designed as a prospective cohort study. Thirty Olympic boxers with a minimum of 45 bouts and 25 non-boxing matched controls were included in the study. CSF samples were collected by lumbar puncture 1–6 days after a bout and after a rest period for at least 14 days. The controls were tested once. Biomarkers for acute and chronic brain injury were analysed. Results NFL (mean ± SD, 532±553 vs 135±51 ng/L p = 0.001), GFAP (496±238 vs 247±147 ng/L p<0.001), T-tau (58±26 vs 49±21 ng/L p<0.025) and S-100B (0.76±0.29 vs 0.60±0.23 ng/L p = 0.03) concentrations were significantly increased after boxing compared to controls. NFL (402±434 ng/L p = 0.004) and GFAP (369±113 ng/L p = 0.001) concentrations remained elevated after the rest period. Conclusion Increased CSF levels of T-tau, NFL, GFAP, and S-100B in >80% of the boxers demonstrate that both the acute and the cumulative effect of head trauma in Olympic boxing may induce CSF biomarker changes that suggest minor central nervous injuries. The lack of normalization of NFL and GFAP after the rest period in a subgroup of boxers may indicate ongoing degeneration. The recurrent head trauma in boxing may be associated with increased risk of chronic traumatic brain injury. PMID:22496755

Overuse of cranial computed tomography scans in children with blunt head trauma unnecessarily exposes them to radiation. The Pediatric Emergency Care Applied Research Network (PECARN) blunt head trauma prediction rules identify children who do not require a computed tomography scan. Electronic health record (EHR) based clinical decision support (CDS) may effectively implement these rules but must only be provided for appropriate patients in order to minimize excessive alerts. To develop, implement and evaluate site-specific groupings of chief complaints (CC) that accurately identify children with head trauma, in order to activate data collection in an EHR. As part of a 13 site clinical trial comparing cranial computed tomography use before and after implementation of CDS, four PECARN sites centrally developed and locally implemented CC groupings to trigger a clinical trial alert (CTA) to facilitate the completion of an emergency department head trauma data collection template. We tested and chose CC groupings to attain high sensitivity while maintaining at least moderate specificity. Due to variability in CCs available, identical groupings across sites were not possible. We noted substantial variability in the sensitivity and specificity of seemingly similar CC groupings between sites. The implemented CC groupings had sensitivities greater than 90% with specificities between 75-89%. During the trial, formal testing and provider feedback led to tailoring of the CC groupings at some sites. CC groupings can be successfully developed and implemented across multiple sites to accurately identify patients who should have a CTA triggered to facilitate EHR data collection. However, CC groupings will necessarily vary in order to attain high sensitivity and moderate-to-high specificity. In future trials, the balance between sensitivity and specificity should be considered based on the nature of the clinical condition, including prevalence and morbidity, in addition to the goals of the intervention being considered.

The management of minor and moderate head trauma in children differs widely between countries. Presently, there are no existing guidelines for management of these children in Scandinavia. The purpose of this study was to produce new evidence-based guidelines for the initial management of head trauma in the paediatric population in Scandinavia. The primary aim was to detect all children in need of neurosurgical intervention. Detection of any traumatic intracranial injury on CT scan was an important secondary aim. General methodology according to the Appraisal of Guidelines for Research and Evaluation (AGREE) II and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system was used. Systematic evidence-based review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology and based upon relevant clinical questions with respect to patient-important outcomes. Quality ratings of the included studies were performed using Quality Assessment of Diagnostic Accuracy Studies (QUADAS)-2 and Centre of Evidence Based Medicine (CEBM)-2 tools. Based upon the results, GRADE recommendations, a guideline, discharge instructions and in-hospital observation instructions were drafted. For elements with low evidence, a modified Delphi process was used for consensus, which included relevant clinical stakeholders. The guidelines include criteria for selecting children for CT scans, in-hospital observation or early discharge, and suggestions for monitoring routines and discharge advice for children and guardians. The guidelines separate mild head trauma patients into high-, medium- and low-risk categories, favouring observation for mild, low-risk patients as an attempt to reduce CT scans in children. We present new evidence and consensus based Scandinavian Neurotrauma Committee guidelines for initial management of minor and moderate head trauma in children. These guidelines should be validated before extensive clinical use and updated within four years due to rapid development of new diagnostic tools within paediatric neurotrauma.

The authors present an interesting case of a 19-year-old male who presented as a polytrauma patient following a fall from a height. He was initially managed on the intensive care unit with intracranial pressure bolt monitoring after being intubated and sedated and having his other traumatic injuries stabilized. Upon attempting to wean sedation and extubation a repeat CT scan of the head was undertaken and showed a new area suggested of cerebral infarction, this was a new finding. Further imaging found that he had a cervical vertebral artery dissection following this polytrauma mode of injury. The incidence of vertebral artery dissection following generalized or local trauma is rising but routine imaging/screening in these patients is not undertaken. Our report displays select images related to this case report and emphasizes the consideration of routine imaging in head and neck traumatic injuries to diagnose internal carotid and/or vertebral artery dissections much earlier.

The frequency of head computed tomography (CT) imaging for mild head trauma patients has raised safety and cost concerns. Validated clinical decision rules exist in the published literature and on-line sources to guide medical image ordering but are often not used by emergency department (ED) clinicians. Using simulation, we explored whether the presentation of a clinical decision rule (i.e. Canadian CT Head Rule - CCHR), findings from malpractice cases related to clinicians not ordering CT imaging in mild head trauma cases, and estimated patient out-of-pocket cost might influence clinician brain CT ordering. Understanding what type and how information may influence clinical decision making in the ordering advanced medical imaging is important in shaping the optimal design and implementation of related clinical decision support systems. Multi-center, double-blinded simulation-based randomized controlled trial. Following standardized clinical vignette presentation, clinicians made an initial imaging decision for the patient. This was followed by additional information on decision support rules, malpractice outcome review, and patient cost; each with opportunity to modify their initial order. The malpractice and cost information differed by assigned group to test the any temporal relationship. The simulation closed with a second vignette and an imaging decision. One hundred sixteen of the 167 participants (66.9%) initially ordered a brain CT scan. After CCHR presentation, the number of clinicians ordering a CT dropped to 76 (45.8%), representing a 21.1% reduction in CT ordering (P = 0.002). This reduction in CT ordering was maintained, in comparison to initial imaging orders, when presented with malpractice review information (p = 0.002) and patient cost information (p = 0.002). About 57% of clinicians changed their order during study, while 43% never modified their imaging order. This study suggests that ED clinician brain CT imaging decisions may be influenced by clinical decision support rules, patient out-of-pocket cost information and findings from malpractice case review.

Olfactory loss due to head trauma is a frequent finding. It is attributed to the tearing or severing of the olfactory fibers at the cribriform plate. In contrast, posttraumatic gustatory loss is observed and reported rarely and the underlying mechanism is less understood. Here we present a case of a concomitant post-traumatic anosmia and ageusia. Imaging showed a considerable frontobasal brain damage and it is speculated that the gustatory impairment is due to a central injury of the secondary taste cortex. Based on this observation, we believe that this clinical presentation might be much more frequent than previously reported.

A 7-year-old girl presented with bilaterally dilated pupils, nausea, and vomiting 2 days after head trauma. Pilocarpine pupil testing led to the correct diagnosis of pharmacologic pupillary dilation from an unexpected and unusual source of plant poisoning, Solanum dulcamara (blue nightshade). In patients with internal ophthalmoplegia, awareness of the possibility of pharmacologic mydriasis and correct use of topical pilocarpine testing can preclude the necessity for neuroradiologic and invasive diagnostic studies, even in cases with atypical or complex presentations.

Magnetic resonance imaging findings in the evaluation of traumatic anosmia.

Head trauma is a common cause of anosmia, but diagnosis is typically late, owing to more life-threatening sequelae of the injury. Herein, we describe our workup for a case of traumatic anosmia and the magnetic resonance imaging (MRI) findings both at the time of injury and at the 18-month follow-up. We present a case report and a review of the literature. A 33-year-old woman presented to our institution with a chief complaint of loss of smell and taste following an occipital blow to her head that occurred when she was hit by a car while riding a bicycle. We present the findings of MRI performed at the time of the injury and at the 18-month follow-up. We describe the clinical progression of her disease, from symptoms of parosmic and phantosmic episodes accompanied by dysgeusia to total anosmia at the 18-month follow-up. We advocate the use of MRI, coupled with otolaryngology consultation and formal olfactory testing, in the diagnosis, management, and counseling of patients with anosmia sustained from head injury.

Fever is strongly associated with poor outcome after traumatic brain injury (TBI). We hypothesized that early fever is a direct result of brain injury and thus would be more common in TBI than in patients without brain injury and associated with inflammation. We prospectively enrolled patients with major trauma with and without TBI from a busy Level I trauma center intensive care unit (ICU). Patients were assigned to one of four groups based on their presenting Head Abbreviated Injury Severity Scale scores: multiple injuries: head Abbreviated Injury Scale (AIS) score greater than 2, one other region greater than 2; isolated head: head AIS score greater than 2, all other regions less than 3; isolated body: one region greater than 2, excluding head/face; minor injury: no region with AIS greater than 2. Early fever was defined as at least one recorded temperature greater than 38.3°C in the first 48 hours after admission. Outcome measures included neurologic deterioration, length of stay in the ICU, hospital mortality, discharge Glasgow Outcome Scale-Extended, and plasma levels of seven key cytokines at admission and 24 hours (exploratory). Two hundred sixty-eight patients were enrolled, including subjects with multiple injuries (n = 59), isolated head (n = 97), isolated body (n = 100), and minor trauma (n = 12). The incidence of fever was similar in all groups irrespective of injury (11-24%). In all groups, there was a significant association between the presence of early fever and death in the hospital (6-18% vs. 0-3%), as well as longer median ICU stays (3-7 days vs. 2-3 days). Fever was significantly associated with elevated IL-6 at admission (50.7 pg/dL vs. 16.9 pg/dL, p = 0.0067) and at 24 hours (83.1 pg/dL vs. 17.1 pg/dL, p = 0.0025) in the isolated head injury group. Contrary to our hypothesis, early fever was not more common in patients with brain injury, though fever was associated with longer ICU stays and death in all groups. Additionally, fever was associated with elevated IL-6 levels in isolated head injury. Prognostic and Epidemiological study, level III.

The radiologist's role in child abuse: imaging protocol and differential diagnosis.

PubMed

Delgado Álvarez, I; de la Torre, I Barber Martínez; Vázquez Méndez, É

2016-05-01

Child abuse or nonaccidental trauma is a major problem worldwide; in Spain, there are about 12,000 victims per year. The detection of specific lesions or findings that are incongruent with the reported mechanism of trauma mean that radiologists are often the physician responsible for sounding the alarm in cases of abuse. The triad consisting of subdural hematoma, metaphyseal fracture, and posterior rib fractures is very characteristic of the battered child syndrome. The finding of acute and chronic lesions in the same patient is highly specific for nonaccidental trauma. Fractures of long bones in patients who have yet begun to walk should also alert to possible child abuse. Lesions that are highly specific for abuse, such as classic metaphyseal fractures or posterior rib fractures, can be difficult to demonstrate radiographically and are usually clinically occult. The American College of Radiology (ACR) protocols recommend obtaining three separate X-rays of each upper and lower limb. It is important to use X-ray systems that give high resolution images with low kilovoltage (50-70 kvp) and appropriate milliamperage. A skeletal survey consisting of a series of images collimated to each body region is recommended for all children under the age of two years in whom abuse is suspected. A follow-up skeletal survey about two weeks after the initial survey is useful for detecting new fractures and for assessing the consolidation of others, which helps in dating the lesions. Head injuries are the leading cause of death in abused children. Although computed tomography is the first neuroimaging technique in nonaccidental trauma, magnetic resonance imaging of the head can better characterize the lesions seen on computed tomography and can help to estimate the age of the lesions.

 Liquid posterior fossa epidural hematoma (LPFEH) following head trauma is uncommon, and very few such cases have been described in the literature. Eight patients with this entity and their treatments are presented here.  We performed a single-institution retrospective analysis of all patients with diagnosed LPFEH over a 3-year period. Collected data included clinical history, laboratory results, treatment, and review of all imaging studies performed.  Eight pediatric cases were identified with imaging findings consistent with LPFEH; no adult case was identified. Enlargement of ventricles appeared on computed tomography (CT) in six cases, and secondary epilepsy onset occurred in three cases with severe dilated ventricles. Routine hematologic and coagulation tests failed to disclose anemia or abnormal coagulation in each case. Five patients underwent burr-hole drainage of the hematoma and recovered completely. Conservative therapy was adopted in three patients for small hematomas, and hematoma enlargement was not observed in the follow-up CT scans.  LPFEH is a rare subtype of traumatic epidural hematoma specifically recognized in the pediatric population. Minimally invasive burr-hole drainage is a feasible procedure for the patient with evident space-occupying effect. Coagulation dysfunction or low hemoglobin as a possible contributing factor and its role in formation of LPFEH was excluded. Georg Thieme Verlag KG Stuttgart · New York.

A prospective evaluation for occult pneumothorax was performed in 25 consecutive patients with serious head trauma by combining a limited chest CT examination with the emergency head CT examination. Of 21 pneuomothoraces present in 15 patients, 11 (52%) were found only by chest CT and were not identified clinically or by supine chest radiograph. Because of pending therapeutic measures, chest tubes were placed in nine of the 11 occult pneumothoraces, regardless of the volume. Chest CT proved itself as the most sensitive method for detection of occult pneumothorax, permitting early chest tube placement to prevent transition to a tension pneumothoraxmore » during subsequent mechanical ventilation or emergency surgery under general anesthesia.« less

To determine incidence and etiologies of craniofacial injuries in the pediatric population through comparison of injuries caused by all-terrain vehicles and golf cart trauma. Case series with chart review. Level 1 trauma center. Retrospective review of pediatric traumas at a tertiary academic medical center from 2003 to 2012 identified 196 patients whose injuries resulted from accidents involving either all-terrain vehicles or golf carts. Data was collected and variables such as age, gender, driver vs. passenger, location of accident, Glasgow coma scale, Injury severity scale, Abbreviated injury scale, and presence or absence of helmet use were examined. 196 pediatric patients were identified: 68 patients had injuries resulting from golf cart accidents, and 128 patients from ATV accidents. 66.4% of ATV-related traumas were male, compared to 52.9% of golf cart-related traumas. Ages of injured patients were similar between the two modalities with average age of ATV traumas 10.8 (±4.0) years and golf cart traumas 10.0 (±4.6) years. Caucasians were most commonly involved in both ATV (79.7%) and golf cart traumas (85.3%). 58.6% of all ATV related trauma and 69.1% of all golf cart trauma resulted in craniofacial injuries. The most common craniofacial injury was a closed head injury with brief loss of consciousness, occurring in 46.1% of the ATV traumas and 54.4% of the golf cart traumas. Temporal bone fractures were the second most common type of craniofacial injury, occurring in 5.5% of ATV accidents and 7.4% of the golf cart traumas. Length of hospital stay and, cases requiring surgery and severity scores were similar between both populations. Intensive care admissions and injury severity scores approached but not reach statistical significance (0.096 and 0.083, respectively). The only statistically significant differences between the two modalities were helmet use (P=0.00018%) and days requiring ventilator assistance (P=0.025). ATVs and golf carts are often exempt from the safety features and regulations required of motor vehicles, and ATV and golf cart accidents represent a significant portion of pediatric traumas. This study found that ATV and golf cart accidents contribute significantly to craniofacial trauma requiring hospitalization, with resultant morbidity and mortality. Further investigation of these injuries and their prevention in the pediatric population is needed before efforts to promote effective safety regulations for such vehicles in the future can be addressed.

2013-01-01

Due to its advantages, ceramic-on-ceramic bearings have been widely used in young patients for almost 30 years. Long-term survivorship, low wear, and low biological reactivity to particles are some of its characteristics. Even though this material has had a lot of improvements, the risk of fracture is one of the concerns. There have been reports of fracture of ceramic in the acetabular liner and head but no fractures of both in the same patient. We report a case of a fracture in a sandwich type acetabular liner and the ceramic head in a patient involving ankylosing spondylitis. It occurred three years after the operation and with no history of direct trauma. We decided to change the bearing surfaces to metal polyethylene without removing the metal back. The patient is satisfied by the clinical results after a 5-year followup. PMID:23691392

One of the more serious adverse outcomes of military airborne operations is closed-head injuries. This investigation examined risk factors for closed-head injuries in an Army airborne infantry unit. Closed-head injuries were defined as energy exchanges in which the head contacted the ground or an object and the soldier sought medical care for external trauma, headache, loss of consciousness, or altered mental state. Injury data were obtained by investigators in the drop zone and diagnoses were confirmed by a physician. Operational data on potential injury risk factors were obtained from routine reports published by the infantry unit. Weather data were obtained using a pocket weather tracker. There were 96,132 jumps resulting in 310 closed-head injuries for a crude incidence of 3.22/1000 jumps. In 98% of known cases the injury was associated with parachute landings. Multivariate logistic regression revealed that independent risk factors for closed-head injuries included night jumps, combat loads, higher wind speeds, higher temperatures, enlisted rank, and entanglements. This study identifies the current incidence and extrinsic risk factors for closed-head injuries during military airborne operations. Although it is necessary to conduct airborne training under realistic conditions, trainers and commanders should be aware of these risks and plan airborne operations accordingly.

Fluid resuscitation of the trauma patient: How much is enough?

PubMed Central

Hamilton, Stewart M.; Breakey, Pat

1996-01-01

Patient management in the prehospital resuscitative phase after trauma is vitally important to the outcome. Early definitive care remains the essential element in improving morbidity and mortality. In Canada, where a large proportion of trauma occurs at sites distant from a trauma centre, the prehospital resuscitative phase is long and has even greater potential to affect outcome. Conventional teaching about the end points of resuscitation has promoted the concept of normalization of hemodynamic parameters with maintenance of end-organ perfusion, as measured by the hourly urine output. Recent work in patients with a closed head injury and in patients with penetrating torso trauma challenge the notion that trauma patients are homogeneous with respect to these end points. In the Canadian setting of blunt injury, where a closed head injury is usually suspected and often present, the evidence from clinical studies suggests that an aggressive approach to maintaining blood pressure is warranted. In penetrating torso injury in an urban setting, there is evidence to suggest that delaying resuscitation until hemorrhage is controlled is beneficial. More Canadian clinical trials are required in this area. In the meantime, the priorities of resuscitation must be carefully assessed for each patient and pattern of injury. PMID:8599784

Multidetector computed tomography (MDCT) characterised by speed and precision is increasingly accessible in emergency wards. The aim of our study was to determine the most common injuries to the chest region, as well as type associated extrathoracic injuries, and the treatment outcome. This prospective study included 61 patients with blunt trauma who were submitted to computed tomography (CT) of the thorax. The number of injuries was evaluated by organs and organ systems of the chest. The cause of the injury, the length and the outcome of the treatment, and the presence of injuries in other regions were assessed. Chest injuries were associated with injuries to other regions in 80.3% cases, predominantly injuries to extremities or pelvic bones in 54.1% cases, followed by head injuries in 39.3% patients. Associated thoracic injuries were present in 90.9% of patients with lethal outcome. Lung parenchymal lesions, pleural effusions and rib fractures were the most common injuries affecting 77.1%, 65.6% and 63.9% of the cases, respectively. Blunt chest trauma is a significant problem affecting predominantly males in their forties and it is usually caused by a motor vehicle accident. In case of pneumomediastinum or mediastinal haematoma, the use of 3D reconstructions is advised for diagnosing possible tracheobronchial ruptures and thoracic aorta injuries. Increased resolution of CT scanners yielded a large number of findings that are occult on radiography, especially in the event of lung parenchymal and pleural injuries. However, none imaging modality can replace surgical judgement.

Falls are a major cause of morbidity in the elderly. We describe the low-acuity elderly fall population and study which historical and clinical features predict traumatic intracranial injuries (ICIs). This is a prospective observational study of patients at least 65 years old presenting with fall to a tertiary care facility. Patients were eligible if they were at baseline mental status and were not triaged to the trauma bay. At presentation, a data form was completed by treating physicians regarding mechanism and position of fall, history of head strike, headache, loss of consciousness (LOC), and signs of head trauma. Radiographic imaging was obtained at the discretion of treating physicians. Medical records were subsequently reviewed to determine imaging results. All patients were called in follow-up at 30 days to determine outcome in those not imaged. The study was institutional review board approved. A total of 799 patients were enrolled; 79.5% of patients underwent imaging. Twenty-seven had ICIs (3.4%). Fourteen had subdural hematoma, 7 had subarachnoid hemorrhage, 3 had cerebral contusion, and 3 had a combination of injuries. Logistic regression demonstrated 2 study variables that were associated with ICIs: LOC (odds ratio, 2.8; confidence interval, 1.2-6.3) and signs of head trauma (odds ratio, 13.2; confidence interval, 2.7-64.1). History of head strike, mechanism and position, headache, and anticoagulant and antiplatelet use were not associated with ICIs. Elderly fall patients who are at their baseline mental status have a low incidence of ICIs. The best predictors of ICIs are physical findings of trauma to the head and history of LOC.

Trauma registries play an integral role in trauma systems but their valid use hinges on data quality. The aim of this study was to determine, among contemporary publications using trauma registry data, the level of reporting of data completeness and the methods used to deal with missing data. A systematic review was conducted of all trauma registry-based manuscripts published from 01 January 2015 to current date (17 March 2017). Studies were identified by searching MEDLINE, EMBASE, and CINAHL using relevant subject headings and keywords. Included manuscripts were evaluated based on previously published recommendations regarding the reporting and discussion of missing data. Manuscripts were graded on their degree of characterization of such observations. In addition, the methods used to manage missing data were examined. There were 539 manuscripts that met inclusion criteria. Among these, 208 (38.6%) manuscripts did not mention data completeness and 88 (16.3%) mentioned missing data but did not quantify the extent. Only a handful (n = 26; 4.8%) quantified the 'missingness' of all variables. Most articles (n = 477; 88.5%) contained no details such as a comparison between patient characteristics in cohorts with and without missing data. Of the 331 articles which made at least some mention of data completeness, the method of managing missing data was unknown in 34 (10.3%). When method(s) to handle missing data were identified, 234 (78.8%) manuscripts used complete case analysis only, 18 (6.1%) used multiple imputation only and 34 (11.4%) used a combination of these. Most manuscripts using trauma registry data did not quantify the extent of missing data for any variables and contained minimal discussion regarding missingness. Out of the studies which identified a method of managing missing data, most used complete case analysis, a method that may bias results. The lack of standardization in the reporting and management of missing data questions the validity of conclusions from research based on trauma registry data. Copyright © 2018 Elsevier Ltd.

To estimate the incidence and demographic characteristics associated with road traffic injuries (RTIs) resulting in deaths or hospital admission for 12 hours or more in Viti Levu, Fiji. Analysis of the prospective population-based Fiji Injury Surveillance in Hospitals database (October 2005 - September 2006). Of the 374 RTI cases identified (17% of all injuries), 72% were males and one third were aged 15-29 years. RTI fatalities (10.3 per 100,000 per year) were higher among Indians compared to Fijians. Two-thirds of deaths (largely ascribed to head, chest and abdominal trauma) occurred before hospital admission. While the RTI fatality rate was comparable to the global average for high-income countries, the level of motorisation in Fiji is considerably lower. To avert rising RTI rates with increasing motorisation, Fiji requires a robust road safety strategy alongside effective trauma-care services and a reliable population-based RTI surveillance system. © 2012 The Authors.

Traumatic Brain Injury (TBI) is a significant cause of morbidity and mortality worldwide. Our previous studies showed a high frequency of motor vehicle accidents among neurosurgical patients. However, there is a dearth of data on head injuries in children in Nigeria. To determine the epidemiology of paediatric traumatic brain injuries. This is a prospective analysis of paediatric head trauma at the University of Benin Teaching Hospital, a major referral centre for all traumatic brain injuries in Nigeria between October 2006 and September 2011. We studied the demographic, clinical and radiological data and treatment outcomes. Data was analysed using statistical package for the social sciences (SPSS) 16.0. We managed 127 cases of paediatric head injuries, 65 boys and 62 girls representing 13% of all head injuries managed over the 5-year period. They were aged 3 months to 17 years. The mean age was 7.4 years (median 7 years) with peak incidence occurring at 6-8 years i.e. 31 (24.4%) cases. Motor vehicle accidents resulted in 67.7%, falls 14% and violence 7%. The most frequent computed tomography finding was intracerebral haemorrhage. Mean duration of hospitalization was 18 days (median 11 days). Eleven patients died, mortality correlating well with severity and the presence of intracerebral haematoma. Head injuries in children are due to motor vehicle and motor vehicle-related accidents. Hence, rational priorities for prevention of head injuries in children should include prevention of vehicular, especially pedestrian, accidents in developing countries.

Protective and risk factors in amateur equestrians and description of injury patterns: A retrospective data analysis and a case - control survey

PubMed Central

2011-01-01

Background In Switzerland there are about 150,000 equestrians. Horse related injuries, including head and spinal injuries, are frequently treated at our level I trauma centre. Objectives To analyse injury patterns, protective factors, and risk factors related to horse riding, and to define groups of safer riders and those at greater risk Methods We present a retrospective and a case-control survey at conducted a tertiary trauma centre in Bern, Switzerland. Injured equestrians from July 2000 - June 2006 were retrospectively classified by injury pattern and neurological symptoms. Injured equestrians from July-December 2008 were prospectively collected using a questionnaire with 17 variables. The same questionnaire was applied in non-injured controls. Multiple logistic regression was performed, and combined risk factors were calculated using inference trees. Results Retrospective survey A total of 528 injuries occured in 365 patients. The injury pattern revealed as follows: extremities (32%: upper 17%, lower 15%), head (24%), spine (14%), thorax (9%), face (9%), pelvis (7%) and abdomen (2%). Two injuries were fatal. One case resulted in quadriplegia, one in paraplegia. Case-control survey 61 patients and 102 controls (patients: 72% female, 28% male; controls: 63% female, 37% male) were included. Falls were most frequent (65%), followed by horse kicks (19%) and horse bites (2%). Variables statistically significant for the controls were: Older age (p = 0.015), male gender (p = 0.04) and holding a diploma in horse riding (p = 0.004). Inference trees revealed typical groups less and more likely to suffer injury. Conclusions Experience with riding and having passed a diploma in horse riding seem to be protective factors. Educational levels and injury risk should be graded within an educational level-injury risk index. PMID:21294862

Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease associated with head trauma. Although initially believed to affect only boxers, the at-risk population has expanded to encompass a much wider demographic, including American football players, hockey players, wrestlers, and military veterans. This expansion has garnered considerable media attention and public concern for the potential neurodegenerative effects of head trauma. The main aim of this systematic review is to give a complete overview of the common findings and risk factors for CTE as well as the status quo regarding the incidence and prevalence of CTE. This systematic review was performed using PubMed and MEDLINE and includes all neuropathologically confirmed cases of CTE in the medical literature to date, from the first published case in 1954 to August 1, 2013 (n = 153). The demographics, including the primary source of mTBI (mild Traumatic Brain Injury), age and cause of death, ApoE genotype, and history of substance abuse, when listed, were obtained from each case report. The demographics of American football players found to have CTE are also presented separately in order to highlight the most prevalent group of CTE cases reported in recent years. These 153 case reports of CTE represent the largest collection to date. We found that a history of mTBI was the only risk factor consistently associated with CTE. In addition, we found no relationships between CTE and age of death or abnormal ApoE allele. Suicide and the presence of premorbid dementia was not strongly associated with CTE. We conclude that the incidence of CTE remains unknown due to the lack of large, longitudinal studies. Furthermore, the neuropathological and clinical findings related to CTE overlap with many common neurodegenerative diseases. Our review reveals significant limitations of the current CTE case reporting and questions the widespread existence of CTE in contact sports.

Spontaneous disappearance of two asymptomatic arachnoid cysts in two different locations.

PubMed

Cokluk, C; Senel, A; Celik, F; Ergür, H

2003-04-01

We report two children with asymptomatic arachnoid cysts which resolved spontaneously without any surgical intervention and history of major head and body trauma. The first child was a 10-year-old boy with an arachnoid cyst in the right sylvian fissure. The second child was a 1-year-old girl with a right cerebral convexity arachnoid cyst. Both of them were asymptomatic. Arachnoid cysts spontaneously disappeared within 2 years following initial diagnosing. There was no major head and body trauma except usual home, school and sports activity. We speculated that the cysts ruptured into cerebrospinal fluid circulation by the mechanical effects of some forced activities to the brain tissue and cyst, such as excessive breathing, coughing and sport activities. These factors may change the balance between intracystic and pericystic pressure and facilitate the rupturing of the cyst into subdural, subarachnoid and intraventricular spaces. These cases demonstrate that neurosurgical intervention of asymptomatic arachnoid cysts is not absolutely indicated in the paediatric age group. Close follow up with computerized tomography (CT) and magnetic resonance imaging (MRI) is a treatment option in the patient with arachnoid cysts located in the middle cranial fossa and cerebral convexity.

1997-08-01

In 1994, a retrospective study of new cases of traumatic Spinal Cord Injury (SCI) was conducted in all the hospitals in Southeast Turkey: 75 new traumatic SCI were identified. The estimated annual incidence was 16.9 per million population. The male/female ratio was 5.8/1. The mean age was 31.3, being 31.25 for male patients and 31.36 for female patients. 70.7% of all patients were under the age of 40. The major causes of SCI were falls (37.3%) and gunshot wounds (29.3%), followed by car accidents (25.3%), and stab wounds (1.3%). Thirty one patients (41.3%) were tetraplegic and 44 (58.7%) paraplegic. In tetraplegic patients the commonest level was C5, in those with paraplegia L1. The commonest associated injury was head trauma followed by fractures of the extremity(ies). Severe head trauma, being a major cause of death, may have obscured the actual incidence of SCI. Most of gunshot injured SCI patients were young soldiers fighting against the rebels. As there was no available data for the rebels with SCI, the actual incidence of SCI in Southeast (SE) Turkey should be higher than that found in this study.

Post-traumatic language and memory impairment, as well as a subsequent recovery in monolinguals have been widely documented in the literature, yet little is known about learning the second language after a severe head trauma followed by coma, as well as the relationship of this process with cognitive recovery, psychological status and quality of life. The present study investigates the relationship of learning the second language (English) in the process of rehabilitation, with quality of life in a Polish female university student who, as a result of a car accident, suffered a major closed-head injury and was comatose for a month. The subject was enrolled in an English learning program nine months after the trauma. The experiment lasted six months and comprised monthly meetings. The patient improved the major components of the second language, including vocabulary. Within the 6 months, the subject was gradually capable of learning additional and more complex lexical items. Learning the second language after traumatic brain injury may positively influence emotional well-being, self-esteem, and, perhaps, recovery of quality of life. A long-term beneficial effect of learning L2 was a consequential improvement of the patient's memory.

To report on 4 cases of avascular necrosis of the metacarpal head. We retrospectively reviewed 4 patients who received a diagnosis of avascular necrosis of the metacarpal head and were treated from 2000 to 2016. All patients were males with involvement of the dominant hand. Three patients had a history of trauma and/or fractures in another finger and one had a history of fracture in the same finger. The diagnosis was confirmed on regular x-rays and magnetic resonance imaging. Nonsurgical management was offered to all patients (rest, placement of an orthosis, and nonsteroidal anti-inflammatory drugs) for 3 to 6 months. Two patients responded well to nonsurgical management and improved in their symptoms. One patient refused surgical intervention and continued to have persistent pain. The other patient was treated with curettage and bone graft and had total resolution of pain symptoms with full active range of motion. A high index of suspicion is required to diagnose and treat avascular necrosis of the metacarpal head correctly. Treatment options are numerous and require further studies to investigate their effectiveness in the treatment of this rare disease. Therapeutic V.

Assess characteristics of trauma patients who sustained falls from their own height, more specifically focusing on presence of severe injuries, diagnosis and treatment. Retrospective study including all adult blunt trauma patients admitted in the emergency room in a period of 9 months. Lesions with AIS (Abbreviated Injury Scale)>3 were considered "severe". Variables were compared between victims of fall from their own height (group I) and other blunt trauma mechanisms (group II). Student's t, chi square and Fisher exact tests were used for statistical analysis, considering p<0.05 as significant. Of the 1993 trauma patients included, 305 (15%) were victims of falls from their own height. In group I, mean age was 52.2 ± 20.8 years and 64.8% were male. Injuries in the head segment were the most frequently observed (62.2%), followed by injuries in the extremities (22.3%), thorax (1.3%) and abdomen (0.7%). Severe injuries (AIS>3) were more frequent in the head (8.9%), followed by extremities (4.9%). In group I, craniotomies were needed in 2.3%. By comparing groups, we observed that victims of falls from their own height had significantly higher mean age, higher mean systolic blood pressure, and higher head AIS mean, as well as lower ISS mean, thorax AIS mean, abdomen AIS mean and extremities AIS mean. Importance of the trauma mechanism in victims of falls from own height should be emphasized due to a considerable possibility of occult severe injuries, mainly in the cephalic segment.

The outcome of head trauma as a result of road accident rests with increased use of CT scan and other radiological imaging modalities for prompt diagnosis is important. To find out the time of presentation for CT scan, symptoms for referral for CT scan and pattern of injuries in patients with cranial CT scan following road traffic accidents. Retrospective analysis of cranial computed tomography (CT) films, request cards, duplicate copy of radiology reports, soft copy CT images and case notes of 61 patients who underwent cranial CT scan on account of road traffic accidents. The study CT scans were performed at the radiology department of University Teaching Hospital between 1st January 2002 and 31st December 2004. 51 patients (83.6%) were male while 10 (16.4%) were female with male to female ratio of 5:1. Thirty - eight (62.3%) patients were aged 20-39 years. Forty two patients (68.9%) presented after one week of injury. No patient presented within the first six hours of injury. The symptoms needing referral for CT scan included head injury 30 (49.2%), seizures 10 16.4%), skull fractures 8 (13.1%) and persistent headache 6 (5.6%). A total of 113 lesions were seen as some patients presented with more than one lesion. The findings on CT scan included 10 patients with normal findings , 21 (34.4%) skull fractures , 21 (34.4%) intra-cerebral haemorrhage , 19 (31.2%) brain contusion , 18 (29.5%) paranasal sinus collection,11 (18.0%) cerebral oedema, 10 (16.4%) subdural haematoma and 5 (8.2%) epidural haematoma. Over 80% of the subdural and epidural haematomas were associated with skull fractures. The yield from plain radiography was poor being positive in only 8 (13.1%) while CT scan was positive in 51 (83.61%). Also 75 (about 66%) of the 113 lesions seen on CT scan were treatable surgically. CT scan is an effective imaging modality of patient with road traffic accident and should be promptly requested in symptomatic patients who sustain trauma to the head toward identification of lesions that are amenable to surgical treatment.

Abusive head trauma and accidental head injury: a 20-year comparative study of referrals to a hospital child protection team

Aim To describe children referred for suspected abusive head trauma (AHT) to a hospital child protection team in Auckland, New Zealand. Methods Comparative review of demographics, histories, injuries, investigations and diagnostic outcomes for referrals under 15 years old from 1991 to 2010. Results Records were available for 345 children. Referrals increased markedly (88 in the first decade, 257 in the second), but the diagnostic ratio was stable: AHT 60%, accidental or natural 29% and uncertain cause 11%. The probability of AHT was similar regardless of socio-economic status or ethnicity. In children under 2 years old with accidental head injuries (75/255, 29%) or AHT (180/255, 71%), characteristics of particular interest for AHT included no history of trauma (88/98, 90%), no evidence of impact to the head (84/93, 90%), complex skull fractures with intracranial injury (22/28, 79%), subdural haemorrhage (160/179, 89%) and hypoxic ischaemic injury (38/39, 97%). In children over 2 years old, these characteristics did not differ significantly between children with accidental head injuries (21/47, 45%) and AHT (26/47, 55%). The mortality of AHT was higher in children over 2 years old (10/26, 38%) than under 2 years (19/180, 11%). Conclusions The striking increase in referrals for AHT probably represents increasing incidence. The decision to refer a hospitalised child with a head injury for assessment for possible AHT should not be influenced by socio-economic status or ethnicity. Children over 2 years old hospitalised for AHT are usually injured by mechanisms involving impact and should be considered at high risk of death. PMID:26130384

Measuring long-term disability and functional outcomes after major trauma is not standardized across trauma registries. An ideal measure would be responsive to change but not have significant ceiling effects. The aim of this study was to compare the responsiveness of the Glasgow Outcome Scale (GOS), GOS-Extended (GOSE), Functional Independence Measure (FIM), and modified FIM in major trauma patients, with and without significant head injuries. Patients admitted to two adult Level I trauma centers in Victoria, Australia, who survived to discharge from hospital, were aged 15 years to 80 years with a blunt mechanism of injury, and had an estimated Injury Severity Score >15 on admission, were recruited for this prospective study. The instruments were administered at baseline (hospital discharge) and by telephone interview 6 months after injury. Measures of responsiveness, including effect sizes, were calculated. Bootstrapping techniques, and floor and ceiling effects, were used to compare the measures. Two hundred forty-three patients participated, of which 234 patients (96%) completed the study. The GOSE and GOS were the most responsive instruments in this major trauma population with effect sizes of 5.3 and 4.4, respectively. The GOSE had the lowest ceiling effect (17%). The GOSE was the instrument with greatest responsiveness and the lowest ceiling effect in a major trauma population with and without significant head injuries and is recommended for use by trauma registries for monitoring functional outcomes and benchmarking care. The results of this study do not support the use of the modified FIM for this purpose.

Blunt trauma is the most frequent mechanism of injury in multiple trauma, commonly resulting from road traffic collisions or falls. Two of the most frequent injuries in patients with multiple trauma are chest trauma and extremity fracture. Several trauma mouse models combine chest trauma and head injury, but no trauma mouse model to date includes the combination of long bone fractures and chest trauma. Outcome is essentially determined by the combination of these injuries. In this study, we attempted to establish a reproducible novel multiple trauma model in mice that combines blunt trauma, major injuries and simple practicability. Ninety-six male C57BL/6 N mice (n = 8/group) were subjected to trauma for isolated femur fracture and a combination of femur fracture and chest injury. Serum samples of mice were obtained by heart puncture at defined time points of 0 h (hour), 6 h, 12 h, 24 h, 3 d (days), and 7 d. A tendency toward reduced weight and temperature was observed at 24 h after chest trauma and femur fracture. Blood analyses revealed a decrease in hemoglobin during the first 24 h after trauma. Some animals were killed by heart puncture immediately after chest contusion; these animals showed the most severe lung contusion and hemorrhage. The extent of structural lung injury varied in different mice but was evident in all animals. Representative H&E-stained (Haematoxylin and Eosin-stained) paraffin lung sections of mice with multiple trauma revealed hemorrhage and an inflammatory immune response. Plasma samples of mice with chest trauma and femur fracture showed an up-regulation of IL-1β (Interleukin-1β), IL-6, IL-10, IL-12p70 and TNF-α (Tumor necrosis factor- α) compared with the control group. Mice with femur fracture and chest trauma showed a significant up-regulation of IL-6 compared to group with isolated femur fracture. The multiple trauma mouse model comprising chest trauma and femur fracture enables many analogies to clinical cases of multiple trauma in humans and demonstrates associated characteristic clinical and pathophysiological changes. This model is easy to perform, is economical and can be used for further research examining specific immunological questions.

The Monteggia fracture is one of the pitfalls of conventional diagnosis of upper limb trauma. Through a retrospective study of 20 cases diagnosed at the Department of Orthopaedic Surgery and Traumatology, University Hospital Center, Ibn Sina, Mohamed V University, Rabat, Morocco, between 2010 and 2014, we have tried to do an update on the management of Monteggia fractures either at of paraclinical exams or the surgical management. We support the idea that the dislocation of the radial head should be sought systematically to any isolated fracture of the ulna, for not to miss fracture Monteggia authentic. Rehabilitation of the upper limb must be done as soon as possible. PMID:25667713

Whiplash Associated Disorders (WAD) has been reported as an adult phenomenon. Whiplash injury has classically been described as a cervical soft tissue hyperextension- flexion injury after a trauma such as a rear end impact car crash, contact sport injuries, blows to the head from a falling object or a punch and shaken baby syndrome and is mostly seen in adults . It is important as it may cause severe disability due to spinal cord injury, decrease work productivity and even retropharyngeal hematoma resulting airway obstruction and mortality due to bleeding amongst deep cervical fascias. We describe a case of retropharyngeal hematoma after whiplash injury in a childhood.

The impact of risk-taking behavior among adolescent blunt trauma patients is not fully appreciated. This study examined the relationship between adolescent risk-taking behaviors, the resultant injury severity, and outcome for blunt trauma. Between January 2000 and December 2005, data were collected on adolescent blunt trauma patients (12-18 years) admitted to either a Level I adult trauma center or large urban pediatric hospital. Five groups of risk-taking behavior were examined: ATV riders, drug and alcohol users, unhelmeted motorcyclists, unhelmeted extreme sports participants and unrestrained motor vehicle occupants. Demographic data, mechanism of injury, injury severity, hospital course and outcomes were evaluated for each group. A total of 2030 adolescents were admitted following blunt trauma; 723 adolescents (36%) were engaged in risk-taking behavior at the time of their injury. Most patients were male (68%). Unrestrained MVA occupants were the most frequently encountered risk takers (37%); among this subset, most were unrestrained passengers (74%). Head injuries were frequent (22%) among risk takers. When compared to non-risk-takers, there were no significant age, race, gender, or ISS differences. However, a significantly higher number of positive head CT scans were found among risk-taking adolescents (22%, p < 0.05). Mortality was low (3%). Risk-taking behavior is prevalent among adolescent blunt trauma patients. Improved injury prevention strategies are needed to discourage these behaviors during adolescence.

The evolution of medical practice is resulting in increasing subspecialisation, with head, face and neck (HFN) trauma in a civilian environment usually managed by a combination of surgical specialties working as a team. However, the full combination of HFN specialties commonly available in the NHS may not be available in future UK military-led operations, necessitating the identification of a group of skill sets that could be delivered by one or more deployed surgeons. A systematic review was undertaken to identify those surgical procedures performed to treat acute military head, face, neck and eye trauma. A multidisciplinary consensus group was convened following this with military HFN trauma expertise to define those procedures commonly required to conduct deployed, in-theatre HFN surgical combat trauma management. Head, face, neck and eye damage control surgical procedures were identified as comprising surgical cricothyroidotomy, cervico-facial haemorrhage control and decompression of orbital haemorrhage through lateral canthotomy. Acute in-theatre surgical skills required within 24 hours consist of wound debridement, surgical tracheostomy, decompressive craniectomy, intracranial pressure monitor placement, temporary facial fracture stabilisation for airway management or haemorrhage control and primary globe repair. Delayed in-theatre procedures required within 5 days prior to predicted evacuation encompass facial fracture fixation, delayed lateral canthotomy, evisceration, enucleation and eyelid repair. The identification of those skill sets required for deployment is in keeping with the General Medical Council's current drive towards credentialing consultants, by which a consultant surgeon's capabilities in particular practice areas would be defined. Limited opportunities currently exist for trainees and consultants to gain experience in the management of traumatic head, face, neck and eye injuries seen in a kinetic combat environment. Predeployment training requires that the surgical techniques described in this paper are covered and should form the curriculum of future military-specific surgical fellowships. Relevant continued professional development will be necessary to maintain required clinical competency. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Multiple inflicted injuries in traumatic deaths usually indicate homicide. Three cases are reported where homicide was initially suspected due to findings at the death scene and the apparent nature of the injuries however, after investigation, involvement of any other individuals in the deaths could be excluded. Case 1: A 52-year-old male was found with multiple stab wounds. At autopsy, 36 stab wounds were identified, the majority of which were superficial. Only two stab wounds had penetrated deeply. Case 2: A 19-year-old female was found with three gunshot entry wounds to the right temple and a .22 calibre automatic rifle resting across her lap. Case 3: A 47-year-old female was found with numerous haematomas and three deep head wounds in keeping with trauma from impact with a blunt object. A high level of clozapine was detected on toxicological analysis of blood and a history of schizophrenia was reported. Although multiple self-inflicted wounds are most often caused by sharp objects such as knives, on occasion multiple gunshot wounds and rarely, blunt trauma may also be encountered. Careful integration of scene and autopsy findings may be required to avoid misinterpretation of the circumstances and manner of death.

Younghein, John A; Eskander, Mark S; DeAngelis, Nicola A; Wixted, John J

2012-06-01

Unicameral bone cysts are rare in adults and are most often found incidentally on radiographs. However, they can persist from the adolescent period and may be present in locations that predispose to or exacerbate fractures.This article describes a case of a healthy 40-year-old woman who sustained a proximal humerus trauma that involved a large unicameral bone cyst, resulting in a 3-part head-splitting fracture. The epiphyseal location of the cyst contributed to the severity and extent of the fracture that resulted from a simple fall. Given the age of the patient, open reduction and internal fixation with a locking plate and lag screws was performed. The patient chose open reduction and internal fixation to preserve a hemiarthroplasty procedure in case of future revision. Successful humeral head reconstruction was achieved, and the patient fully recovered. One year postoperatively, the patient underwent arthroscopic debridement to alleviate subjective stiffness and decreased range of motion.Multipart head-splitting fractures require complex repair strategies. The gold standard for the treatment of these injuries is hemiarthroplasty. However, the decision process is difficult in a young patient given the average survival of autoplastic prostheses and the added difficulty of later revision. The current case demonstrates the complexity of decision making resulting from a rare injury in a young, healthy patient and shows that open reduction and internal fixation can provide acceptable reconstruction in such situations.

Objective The aim of this study is to identify the otologic injuries due to handmade explosive-welded blast travma in the law enforcement officers during the combat operations in the curfew security region and to specify the disorders that Otolaryngology and Head Neck Surgery (OHNS) physicians can face during such operations. Methods Medical records of patients in law enforcement who were initially treated by OHNS physicians of Silopi State Hospital during combat operations, between December 14, 2015 and January 15, 2016 were reviewed. Twenty-five patients with otologic injuries due to blast trauma were included in the study. Trauma characteristics, physical examination findings, and beginning treatments were identified. Results Primary blast injury (PBI) was identified as the major disorder in all 24 cases. Tinnitus and hearing loss were the most frequent complaints. In physical examination, tympanic membrane perforations were found in four ears of three patients. Oral methylprednisolone in decreasing doses for 10 days was commenced as an initial treatment in patients with PBI. Secondary blast injury presented in the form of soft tissue damage in the auricular helix due to shrapnel pieces in one patient and a minor surgery was performed. Conclusion Otologic injuries due to blast trauma may often develop during this type of combat operations. Otologic symptoms should be checked, otoscopic examination should be performed, and patients should consult OHNS physicians as soon as possible after trauma. PMID:29392057

Large studies which developed decision rules for the use of Computed tomography (CT) in children with minor head trauma excluded children with late presentation (more than 24h). To assess the prevalence of significant traumatic brain injury (TBI) on CT in infants with head trauma presenting to the emergency department (ED) more than 24h from the injury. A retrospective chart review of infants less than 24 months old referred for head CT because of traumatic brain injury from January 2004 to December 2014 in Assaf-Harofeh medical center was conducted. We used the PECARN definitions of TBI on CT to define significant CT findings. 344 cases were analyzed, 68 with late presentation. There was no significant difference in the age between children with late and early presentation (mean 11.4 (SD 5.6) month vs 10. 5 (SD 7.0) month, P=0.27). There was no significant difference between the groups in the incidence of significant TBI (22% vs 19%, p=0.61). Any TBI on CT (e.g. fracture) was found in 43 (63%) patients with late presentation compared with 116 (42%) patients with early presentation (p=0.002, OR 2.37, 95% CI 1.37-4.1). A similar rate of CT-identified traumatic brain injury was detected in both groups.‏ There was no significant difference in the incidence of significant TBI on CT between the groups.‏ Young children presenting to the ED more than 24 hours after the injury may have abnormal findings on CT.

Head trauma in the cat: 2. assessment and management of traumatic brain injury.

PubMed

Garosi, Laurent; Adamantos, Sophie

2011-11-01

Feline trauma patients are commonly seen in general practice and frequently have sustained some degree of brain injury. Cats with traumatic brain injuries may have a variety of clinical signs, ranging from minor neurological deficits to life-threatening neurological impairment. Appropriate management depends on prompt and accurate patient assessment, and an understanding of the pathophysiology of brain injury. The most important consideration in managing these patients is maintenance of cerebral perfusion and oxygenation. For cats with severe head injury requiring decompressive surgery, early intervention is critical. There is a limited clinical evidence base to support the treatment of traumatic brain injury in cats, despite its relative frequency in general practice. Appropriate therapy is, therefore, controversial in veterinary medicine and mostly based on experimental studies or human head trauma studies. This review, which sets out to describe the specific approach to diagnosis and management of traumatic brain injury in cats, draws on the current evidence, as far as it exists, as well as the authors' clinical experience.

Mitsunaga, Myles M; Yoon, Hyo-Chun

2015-01-01

The purpose of this study was to determine the yield of acutely abnormal findings on head CT scans in patients presenting to the emergency department with dizziness, near-syncope, or syncope and to determine the clinical factors that potentially predicted acutely abnormal head CT findings and hospital admission. We retrospectively reviewed the electronic medical records of all patients presenting to an HMO emergency department between July 1, 2012, and December 31, 2012, who underwent head CT for a primary complaint of dizziness, syncope, or near-syncope. The primary outcomes were head CT scans with acutely abnormal findings and hospital admission. Binary logistic regression was used to assess the association between clinical variables and acute head CT findings and between clinical variables and hospital admission. Of the 253 patients who presented with dizziness, 7.1% had head CT scans with acutely abnormal findings, and 18.6% were admitted. Of the 236 patients who presented with syncope or near-syncope, 6.4% had head CT scans with acutely abnormal findings, and 39.8% were admitted. The following three clinical factors were found to be significantly correlated with acutely abnormal head CT findings: a focal neurologic deficit (p = 0.003), age greater than 60 years (p = 0.011), and acute head trauma (p = 0.026). Our results suggest that most patients presenting with syncope or dizziness to the emergency department may not benefit from head CT unless they are older, have a focal neurologic deficit, or have a history of recent head trauma.

The possibility of establishing causes of death on the basis of the exhumed remains of prisoners executed during the communist regime in Poland: the exhumations at Powązki Military Cemetery in Warsaw.

This study presents the results of the analysis of forensic examinations of the remains of 194 prisoners exhumed at Powązki Military Cemetery in Warsaw. In all probability, most of those buried there were judicially sentenced to death by firing squad or hanging in connection with activities of the Polish independence underground in its struggles with the postwar communist regime. Forensic medical research focussed on determining causes of death and reconstructing the mechanisms of injury leading to death. Most probable causes of death were found in 108 of 194 cases; of these, 76 were isolated gunshot wounds to the head, mostly directed to the occipital region. In 29 of 194 cases, only extensive skull fractures were observed, making it impossible to determine the mechanism of injury. The condition of these skulls do not permit the exclusion of injuries due to gunshots, which were very likely given the historical context of the studied location. In one case, it is assumed that the cause of death could be blunt force trauma to the head. In 86 of 194 cases, it was not possible to determine the cause of death. Of these cases, 20 skeletons were in such poor condition that erosive changes could have completely obliterated even very extensive head injuries leading to death. No injuries were observed that could be associated with execution by hanging.

Penetrating head and neck trauma with construction nails are uncommon life-threatening injuries and an important problem in developing countries. Assessment of the neurovascular and systemic physical status is a first requirement, and the decision concerning which surgical approach to perform for the removal of the nail is of critical importance. A 10-year-old girl was presented one hour after a fall injury with complaint of a swelling and foreign body lodgment on the left forehead. Neurological and systemic physical examinations were normal except for weak direct pupillary light reflex on the left side and the patient's state of uneasiness. Radiological investigations showed that the head of the nail had entered from the left infra-orbital region and become lodged through the orbital roof, below the frontal bone. Surgical extraction of the nail in the operating room was performed successfully using left pterional craniotomy and lateral orbitotomy technique, and there was no complication after surgery. Here, we report a case with a rare craniocerebral penetrating wound and type, with the head of the nail lodged in the anterior fossa through the orbital roof, which may be defined as 'reverse penetration of the nail'.

Major blunt chest injury usually leads to the development of retained hemothorax and pneumothorax, and needs further intervention. However, since blunt chest injury may be combined with blunt head injury that typically requires patient observation for 3-4 days, other critical surgical interventions may be delayed. The purpose of this study is to analyze the outcomes of head injury patients who received early, versus delayed thoracic surgeries. From May 2005 to February 2012, 61 patients with major blunt injuries to the chest and head were prospectively enrolled. These patients had an intracranial hemorrhage without indications of craniotomy. All the patients received video-assisted thoracoscopic surgery (VATS) due to retained hemothorax or pneumothorax. Patients were divided into two groups according to the time from trauma to operation, this being within 4 days for Group 1 and more than 4 days for Group 2. The clinical outcomes included hospital length of stay (LOS), intensive care unit (ICU) LOS, infection rates, and the time period of ventilator use and chest tube intubation. All demographics, including age, gender, and trauma severity between the two groups showed no statistical differences. The average time from trauma to operation was 5.8 days. The ventilator usage period, the hospital and ICU length of stay were longer in Group 2 (6.77 vs. 18.55, p = 0.016; 20.63 vs. 35.13, p = 0.003; 8.97 vs. 17.65, p = 0.035). The rates of positive microbial cultures in pleural effusion collected during VATS were higher in Group 2 (6.7 vs. 29.0%, p = 0.043). The Glasgow Coma Scale score for all patients improved when patients were discharged (11.74 vs. 14.10, p < 0.05). In this study, early VATS could be performed safely in brain hemorrhage patients without indication of surgical decompression. The clinical outcomes were much better in patients receiving early intervention within 4 days after trauma.

Spontaneous or idiopathic intramedullary bleeding is a very rare event in pediatric patients. This diagnosis requires an extended clinical, laboratory, and radiologic work-up to rule out all potential causes of hematomyelia. However, children may present with hematomyelia or spinal cord injury without radiographic abnormality even after a minor trauma. A 15-month-old girl presented with a 24-hour history of progressive neurologic deficits. A trivial trauma had occurred a few days before the clinical onset. Head computed tomography scan and craniospinal magnetic resonance imaging revealed an isolated hemorrhagic central medullary lesion extending from the obex to C3 level. No underlying causes of intramedullary bleeding were identified. In the absence of obvious vascular abnormalities, the patient underwent an urgent occipitocervical decompression with hematoma evacuation. Postoperatively, the patient's motor symptoms rapidly resolved, and she was discharged with cervical collar immobilization. We discuss the differential diagnosis of intramedullary bleeding in children, focusing on the diagnostic protocol and therapeutic options in this age group. Copyright © 2016 Elsevier Inc.

The body of a 19-year-old male was found apparently concealed underneath bushes with recent head and facial trauma, and multiple superficial abrasions. Subsequently, it was discovered that the decedent had been running into objects and buildings following the ingestion the evening before of what was thought to be lysergic acid diethylamide (LSD). Blood staining of a nearby wall close to where the body was lying was in keeping with the described behavior. Toxicology revealed 3,4-methylenedioxymethamphetamine (Ecstasy), in addition to two only recently available drugs 2-(4-bromo-2,5-dimethoxyphenyl)-N-[(2-methoxyphenyl)methyl]ethanamine, (25B-NBOMe), and 1-(3,4-methylenedioxyphenyl)-2-(1-pyrrolidinyl)-1-butanone, (MDPBP). At autopsy, the skull was fractured with cerebral swelling, contusions, and subarachnoid hemorrhage. Death was due to blunt cranial trauma against a background of mixed drug toxicity. The case demonstrates a rare cause of death in a drug-induced acute delirium, as well as highlighting two new designer street drugs that may result in significant aberrant behavior. © 2016 American Academy of Forensic Sciences.

Maxillofacial Fractures and Dental Trauma in a High School Soccer Goalkeeper: A Case Report

PubMed Central

Mihalik, Jason P; Myers, Joseph B; Sell, Timothy C; Anish, Eric J

2005-01-01

Objective: To present the case of a 17-year-old male soccer goalkeeper who sustained maxillofacial fractures and dental trauma after being struck in the face by an opponent's knee. Background: Because of the nature of the sport and a lack of protective headgear, soccer players are at risk for sustaining maxillofacial trauma. Facial injuries can complicate the routine management of on-field medical emergencies often encountered by certified athletic trainers. The appropriate management of maxillofacial trauma on the playing field may help to reduce both the immediate and long-term morbidity and mortality associated with these injuries. Differential Diagnosis: Lacerated superior labial artery, lacerated upper lip, dental fractures, maxillofacial fractures, orbital blowout fracture, closed head injury, cervical spine injury, cerebrovascular accident. Treatment: The athlete received immediate on-field medical care and was subsequently transported to the hospital, where diagnostic testing was performed and further treatment was provided. Hospital inpatient management included dental and plastic surgery. After discharge from the hospital, the athlete underwent several additional dental procedures, including gingival surgery and nonsurgical endodontic treatments. The fractures were followed closely to assure that adequate healing had occurred. The athlete did not return to soccer. Uniqueness: Certified athletic trainers need to be prepared for on-field medical emergencies. Bleeding associated with maxillofacial trauma can complicate basic medical interventions such as airway maintenance. Inappropriate on-field management may result in unnecessary morbidity and mortality for the injured athlete. Therefore, immediate recognition of the severity of the injury is needed in order to institute appropriate airway-management strategies. Conclusions: It is sometimes necessary to consider nonstandard methods of airway management in order to first address heavy bleeding that may be associated with facial trauma. Achieving hemostasis is essential in order to prevent potentially life-threatening complications related to hemorrhage, such as airway obstruction and hypovolemic shock. PMID:15970958

A case-control study to assess factors of possible etiologic significance to dementia of the Alzheimer type was conducted with 78 male cases diagnosed in 1979-1982 at the Veterans Administration Medical Center in Minneapolis, Minnesota and age-race-sex-matched hospital and neighborhood controls (14 of 16 autopsied cases were histopathologically confirmed). Information was obtained on variables relevant to vital, genetic, and immunologic hypotheses, and on possible occupational and environmental exposures, drug use, psychologic stress, smoking, and alcohol consumption. The only major difference between patients with dementia of the Alzheimer type and controls was a significantly greater occurrence of antecedent head trauma in themore » patients (odds ratio = 4.50). This finding is consistent with the literature on posttraumatic dementia but its importance is presently unclear.« less

The Role of Intraoperative Cerebral Angiography in Transorbital Intracranial Penetrating Trauma: A Case Report and Literature Review.

PubMed

Riley, Jonathan P; Boucher, Andrew B; Kim, Denise S; Barrow, Daniel L; Reynolds, Matthew R

2017-01-01

Transorbital intracranial penetrating trauma with a retained intracranial foreign body is a rare event lacking a widely accepted diagnostic and therapeutic algorithm. Intraoperative catheter angiography (IOA) has been advocated by some authorities to rule out cerebrovascular injury before and/or after removal of the object, but no standard of care currently exists. A 19-year-old man was involved in a construction site accident whereby a framing nail penetrated the left globe, traversed the lateral bony orbit, and terminated in the midtemporal lobe. No hematoma or injury to the middle cerebral arteries (MCAs) was apparent on noncontrast head computed tomography (CT) or CT angiography, respectively. The foreign body was removed in the operating room under direct visualization after a frontotemporal craniotomy without incident. No significant venous or arterial bleeding was encountered. All visualized MCA branches appeared intact. Indocyanine green videoangiography performed immediately after object removal showed adequate filling of the MCA branches. Given these uneventful clinical and radiographic findings, IOA was not performed. Postoperative head CT and CT angiography showed no obvious neurovascular injury. On postoperative day 2, the patient was noted to have an expressive aphasia. Cerebral angiography showed absent antegrade filling of the angular artery with some retrograde perfusion. Magnetic resonance imaging confirmed an ischemic infarction in the midtemporal lobe. The patient's expressive aphasia improved to near baseline during his hospitalization and he made an excellent clinical recovery. In transorbital intracranial penetrating trauma with a retained intracranial object, we advocate microsurgical removal of the object under direct visualization followed immediately by IOA. IOA should be strongly considered even in the setting of minimal intraoperative bleeding and normal findings on videoangiography (a course of action that was not followed in the present case). Given that CT angiography and intraoperative videoangiography may miss a potentially treatable traumatic arterial injury, IOA can help determine whether cerebral revascularization may be necessary.

Trauma care at rural level III trauma centers in a state trauma system.

PubMed

Helling, Thomas S

2007-02-01

Although much has been written about the benefits of trauma center care, most experiences are urban with large numbers of patients. Little is known about the smaller, rural trauma centers and how they function both independently and as part of a larger trauma system. The state of Missouri has designated three levels of trauma care. The cornerstone of rural trauma care is the state-designated Level III trauma center. These centers are required to have the presence of a trauma team and trauma surgeon but do not require orthopedic or neurosurgical coverage. The purpose of this retrospective study was to determine how Level III trauma centers compared with Level I and Level II centers in the Missouri trauma system and, secondly, how trauma surgeon experience at these centers might shape future educational efforts to optimize rural trauma care. During a 2-year period in 2002 and 2003, the state trauma registry was queried on all trauma admissions for centers in the trauma system. Demographics and patient care outcomes were assessed by level of designation. Trauma admissions to the Level III centers were examined for acuity, severity, and type of injury. The experiences with chest, abdominal, and neurologic trauma were examined in detail. A total of 24,392 patients from 26 trauma centers were examined, including all eight Level III centers. Acuity and severity of injuries were higher at Level I and II centers. A total of 2,910 patients were seen at the 8 Level III centers. Overall deaths were significantly lower at Level III centers (Level I, 4% versus Level II, 4% versus Level III, 2%, p < 0.001). Numbers of patients dying within 24 hours were no different among levels of trauma care (Level I, 37% versus Level II, 30% versus Level III, 32%). Among Level III centers 45 (1.5%) patients were admitted in shock, and 48 (2%) had a Glasgow Coma Scale score <9. Twenty-six patients had a surgical head injury (7 epidural, 19 subdural hematomas). Twenty-eight patients (1%) needed a chest or abdominal operation. There were 15 spleen and 12 liver injuries with an Abbreviated Injury Score of 4 or 5. Level III trauma centers performed as expected in a state trauma system. Acuity and severity were less as was corresponding mortality. There were a paucity of life-threatening head, chest, and abdominal injuries, which provide a challenge to the rural trauma surgeon to maintain necessary skills in management of these critical injuries.

Machinery-related fatalities are one of the leading causes of traumatic occupational deaths. In our report, we present the case of a 40-year-old male who suffered a severe head trauma while working in a cut-foam industry and died despite an early craniectomy. The radiological reconstruction of the skull based on preoperative computed tomography scans disclosed a large depressed conical fracture of the left parietal bone. The 3D-reconstruction of the work area, combined with a fit-matching analysis between the machinery and the depressed skull fracture allowed us to conclude that the head was crushed between the sliding bar of the cutting device and the metallic protuberance on the opposite side. The case underlines the importance of a detailed workplace investigation and of a thorough evaluation of all circumstantial, clinical, radiological, and autopsy data in the reconstruction of machinery-related fatalities to identify any possible legal responsibilities of the worker and/or the employer.

Effectiveness of the head CT choice decision aid in parents of children with minor head trauma: study protocol for a multicenter randomized trial

PubMed Central

2014-01-01

Background Blunt head trauma is a common cause of death and disability in children worldwide. Cranial computed tomography (CT), the reference standard for the diagnosis of traumatic brain injury (TBI), exposes children to ionizing radiation which has been linked to the development of brain tumors, leukemia, and other cancers. We describe the methods used to develop and test the effectiveness of a decision aid to facilitate shared decision-making with parents regarding whether to obtain a head CT scan or to further observe their child at home. Methods/Design This is a protocol for a multicenter clinician-level parallel randomized trial to compare an intervention group receiving a decision aid, ‘Head CT Choice’, to a control group receiving usual care. The trial will be conducted at five diverse emergency departments (EDs) in Minnesota and California. Clinicians will be randomized to decision aid or usual care. Parents visiting the ED with children who are less than 18-years-old, have experienced blunt head trauma within 24 hours, and have one or two risk factors for clinically-important TBI (ciTBI) from the Pediatric Emergency Care Applied Research Network head injury clinical prediction rules will be eligible for enrollment. We will measure the effect of Head CT Choice on: (1) parent knowledge regarding their child’s risk of ciTBI, the available diagnostic options, and the risks of radiation exposure associated with a cranial CT scan (primary outcome); (2) parent engagement in the decision-making process; (3) the degree of conflict parents experience related to feeling uninformed; (4) patient and clinician satisfaction with the decision made; (5) the rate of ciTBI at seven days; (6) the proportion of patients in whom a cranial CT scan is obtained; and (7) seven-day healthcare utilization. To capture these outcomes, we will administer parent and clinician surveys immediately after each clinical encounter, obtain video recordings of parent-clinician discussions, administer parent healthcare utilization diaries, analyze hospital billing records, review the electronic medical record, and conduct telephone follow-up. Discussion This multicenter trial will robustly assess the effectiveness of a decision aid on patient-centered outcomes, safety, and healthcare utilization in parents of children with minor head trauma in five diverse EDs.

Aminiahidashti, Hamed; Shafiee, Sajad; Sazegar, Mohammad; Nosrati, Nazanin

2016-01-01

Introduction The abducent nucleus is located in the upper part of the rhomboid fossa beneath the fourth ventricle in the caudal portion of the pons. The abducent nerve courses from its nucleus, to innervate the lateral rectus muscle. This nerve has the longest subarachnoid course of all the cranial nerves, it is the cranial nerve most vulnerable to trauma. It has been reported that 1% to 2.7% of all head injuries are followed by unilateral abducent palsy, but bilateral abducent nerve palsy is extremely rare. Case Presentation A 65-year-old woman presented to the emergency department following a motor vehicle accident. A neurological assessment showed the patient’s Glascow coma scale (GCS) to be 15. She complained of double vision, and we found lateral gaze palsy in both eyes. A hangman fracture type IIA (C2 fracture with posterior ligamentous C1 - C2 distraction) was found on the cervical CT scan. A three-month follow-up of the patient showed complete recovery of the abducent nerve. Conclusions Conservative treatment is usually recommended for traumatic bilateral abducent nerve palsy. Our patient recovered from this condition after three months without any remaining neurological deficit, a very rare outcome in a rare case. PMID:27218062

Penetrating Neck Trauma: An Unusual Case Presentation and Review of the Literature.

The aim of this report is to describe a case of a retained projectile metal object to the neck that occurred after airbag deployment during a motor vehicle accident. Case report with literature review. After a motor vehicle accident on the interstate, a 19-year-old man presents to the emergency department for several open extremity fractures, a neck laceration, and a C1 lateral mass fracture. The trauma surgery team repaired the neck laceration with no further evidence of injury. Several weeks later on follow-up, the patient presents with dysphagia and pain when turning his head to the right. A repeat computed tomography angiography (CTA) scan revealed a metallic foreign body in the left posterior pharyngeal, prevertebral soft tissues, which was subsequently removed during exploratory surgery 2 months after his initial accident. This is the first report, to our knowledge, of a projectile metal object to the neck that may be related to airbag deployment. The car involved in this accident was under recall for airbags that were associated with projectile objects, which warrants further investigation into the possible risks of such airbags. © The Author(s) 2016.

Dismembering bodies for display: a bioarchaeological study of trophy heads from the Wari site of Conchopata, Peru.

PubMed

Tung, Tiffiny A

2008-07-01

Human trophy heads from the Wari site of Conchopata (AD 600-1000) are examined to evaluate if recently deceased persons or old corpses were used to make trophy heads and determine if the modifications are standardized. Similarly styled trophy heads may suggest state oversight that ensured uniform modifications, while different styles may suggest that various factions or kin groups prepared them to their own specifications. Other studies often interpret trophy heads as either enemies or ancestors; so, this study addresses that debate by documenting aspects of their identity as revealed through demographic, paleopathological, and trauma data. Results show that "fresh" bodies, not old corpses, were used to make trophies, as evidenced by cutmarks indicating intentional removal of soft tissues. Trophy heads are remarkably standardized; 89% display a hole on the superior of the cranium, apparently a design feature that displays the trophy head upright and facing forward when suspended by a cord. Of the 31 trophy heads, 24 are adolescents/adults and 7 are children, and of the 17 sexed adults, 15 are male and 2 are female. This suggests that adult men and children were favored as trophies. Among 19 observable adult trophy heads, 42% exhibit cranial trauma, suggesting that violence was common among this group. Complementary data on Wari iconography shows warriors wearing trophy heads and Wari deities holding captives and trophy heads. Thus, it is likely that captives (or just their heads) were taken in battles and raids-either secular or ritual-and eventually transformed into trophy heads. (c) 2008 Wiley-Liss, Inc.

An International Classification of Diseases code-based case definition for non-fatal abusive head trauma (AHT) in children <5 years of age was developed in March 2008 by an expert panel convened at the Centers for Disease Control and Prevention (CDC). This study presents an application of the CDC recommended operational case definition of AHT to US hospital inpatient data to characterise the AHT hospitalisation rate for children <5 years of age. Nationwide Inpatient Sample (NIS) data from the Healthcare Cost and Utilisation Project from 2003 to 2008 were examined. Inspection of the NIS data resulted in the identification of an estimated 10 555 non-fatal AHT hospitalisations with 9595 classified as definite/presumptive AHT and 960 classified as probable AHT. The non-fatal AHT rate was highest among children aged <1 year (32.3 per 100 000) with a peak in hospitalisations between 1 and 3 months of age. Non-fatal AHT hospitalisation rates for children <2 years of age were higher for boys (21.9 per 100 000) than girls (15.3 per 100 000). The non-fatal AHT hospitalisation rate showed little variation across seasons. To reduce the burden of AHT in the USA, a preventable public health problem, concerted prevention efforts targeting populations at risk should be implemented. This report demonstrates a model procedure for using the new CDC definition for public health surveillance and research purposes. Such findings can be used to inform parents and providers about AHT (eg, dangers of shaking, strategies for managing infant crying) as well as to monitor better the impact of prevention strategies over time.

Possible environmental, occupational, and other etiologic factors for Parkinson's disease: a case-control study in Germany.

1996-05-01

In a case-control study, we investigated the possible etiologic relevance to Parkinson's disease (PD) of rural factors such as farming activity, pesticide exposures, well-water drinking, and animal contacts; toxicologic exposures such as wood preservatives, heavy metals, and solvents; general anesthesia; head trauma; and differences in the intrauterine environment. We recruited 380 patients in nine German clinics, 379 neighborhood control subjects, and 376 regional control subjects in the largest case-control study investigating such factors and collected data in structured personal interviews using conditional logistic regression to control for educational status and cigarette smoking. The latter was strongly inversely associated with PD. There were significantly elevated odds ratios (OR) for pesticide use, in particular, for organochlorines and alkylated phosphates, but no association was present between PD and other rural factors. A significantly elevated OR was present for exposure to wood preservatives. Subjective assessment by the probands indicated that exposure to some heavy metals, solvents, exhaust fumes, and carbon monoxide was significantly more frequent among patients than control subjects, but this was not confirmed by a parallel assessment of job histories according to a job exposure matrix. Patients had undergone general anesthesia and suffered severe head trauma more often than control subjects, but a dose-response gradient was not present. Patients reported a significantly larger number of amalgam-filled teeth before their illness than control subjects. The frequency of premature births and birth order did not differ between patients and control subjects. Patients reported significantly more relatives affected with PD than control subjects. These results support a role for environmental and genetic factors in the etiology of PD.

To establish the preventable and potentially preventable death rates in a mature trauma center and to identify the causes of death and highlight the lessons learned from these cases. We analyzed data from a Level-1 Trauma Center Registry, collected over a 15-year period. Data on demographics, timing of death, and potential errors were collected. Deaths were judged as preventable (PD), potentially preventable (PPD), or non-preventable (NPD), following a strict external peer-review process. During the 15-year period, there were 874 deaths, 15 (1.7%) and 6 (0.7%) of which were considered PPDs and PDs, respectively. Patients in the PD and PPD groups were not sicker and had less severe head injury than those in the NPD group. The time-death distribution differed according to preventability. We identified 21 errors in the PD and PPD groups, but only 61 (7.3%) errors in the NPD group (n = 853). Errors in judgement accounted for the majority and for 90.5% of the PD and PPD group errors. Although the numbers of PDs and PPDs were low, denoting maturity of our trauma center, there are important lessons to be learned about how errors in judgment led to deaths that could have been prevented.

Trauma deaths outside the hospital: uncovering the typology in Kenyan capital.

Immediate trauma fatality is not amenable to trauma care and primary prevention is the key. The published profiles of deaths due to trauma differ in different regions. Injury mortality rates are higher in developing countries where injury data capture systems are unreliable for prevention purposes. To describe the pattern of pre-hospital injury (immediate) deaths at the Nairobi city mortuary and compare these with hospital (late) trauma deaths. Consecutive trauma autopsies performed over one year (November 2009 to December 2010) at the main mortuary of the Nairobi city council were analyzed for demographic (age, sex, occupation) characteristics, circumstances of the trauma and injury patterns. The patterns of injuries were compared to those of victims who survived and later died at the Kenyatta National Hospital over the same period. Two hundred and thirty seven trauma autopsies were analyzed. The average age of the victims was 29.8 years (range 1-67 years). Christians (93.7%) and males (89.5%) predominated. The place of injury was the road in 32.9% and home/neighborhood in 57.5% of cases. The main mechanisms of fatal injury were traffic (35.4%), gunshot wounds (25.7%) and assault (19.8%). Burns and suicides accounted for 5.9% and 6.3% of fatalities. Most fatalities were intentional (59.4%) Of vehicular injuries, pedestrians predominated (65.5%). For assault, blunt and penetrating injuries accounted for 68.7% and 31.11% of fatalities. Law enforcement officers were responsible for majority of gunshot deaths. Fatal injuries were sustained in single, two and multiple regions in 56.2%, 25.7% and 14.2% of cases. The body region most involved was the head/neck (40.5%). Twelve children under 15 years died. Compared to in-hospital deaths, pre-hospital deaths were associated with intentional injuries, night-time occurrence and preponderance of gun involvement. Injury was a significant cause of mortality among adults of working age in this urban African setting. Intentional injuries predominate in causation of immediate but not late deaths. Local prevention programs should incorporate mortuary data to unravel further aspects of trauma and address violence as a key determinant of prehospital mortality.

Outcomes of coronoid-first repair in terrible triad injuries of the elbow.

Zhang, Junren; Tan, Mark; Kwek, Ernest Beng Kee

2017-09-01

Clinical outcomes of terrible triad injuries (TTIs) of the elbow are historically poor. To date, it is still debatable whether the coronoid needs to be fixed and if so, how and in which sequence. Between 2010 and 2013, 13 patients were treated surgically for acute TTIs of the elbow at a Tertiary Level 1 Trauma Centre by a single surgeon, using a standardized protocol, which included coronoid-brachialis complex fixation via pull-through trans-osseous sutures, radial head fixation or prosthetic replacement and a repair of the lateral ulnar collateral ligament. Repair of the medial collateral ligament (MCL) was done if valgus-stress test demonstrated persistent instability. Patients were then followed-up with clinical and radiological evaluation by the senior author until fracture union and elbow range of motion reached a plateau. Outcomes measured were range of motion, DASH scores and MEPS, as well as surgical complications. Intraoperative stability was achieved in all 13 cases, MCL repair was required in 3 cases and application of external fixation was not required in any case. Patients were followed-up for an average length of 27.7 months and the minimum follow-up period was 12 months. The average age of patients was 46.4 years (range 35-79 years old) at the time of trauma. This included eight Regan-Morrey Type I and five Regan-Morrey Type II coronoid fractures, with ten Mason Type I/II and three Mason Type III radial head fractures. The average arc of ulno-humeral motion was 105.0° (range 80°-135°). The average flexion contracture was 15.0° (range 0°-40°). The average supination-pronation arc was 114.9° (range 0°-180°). The average MEPS was 85 of 100 (range 45-100) and the average DASH score was 21.2 of 100 (range 1.7-61.2). A single case of radio-ulnar synostosis, heterotropic ossification and two cases of recurrent elbow instability were noted. The coronoid-first surgical approach, using a suture-lasso fixation method, has technical benefits for us and showed good clinical success in our series. This is important with postero-medial rotatory instability being common in our series of TTIs. We emphasize not to miss a TTI in an apparently isolated low Mason class radial head fracture.

A 34-year-old man developed posttraumatic epilepsy and a disinhibited orbitofrontal syndrome following severe head trauma at age 22. After an 11-year prison term marked by repeated impulsive aggression, he was transferred to a state psychiatric hospital. Replacement of phenytoin by valproic acid resulted in a 100-lb weight gain, exacerbation of sleep apnea, and right heart failure. Despite replacement of valproate with topiramate, he died of a cardiorespiratory arrest during a seizure. This case illustrates the potential risks associated with valproate therapy in the obese brain-damaged population.

BACKGROUND: The objective of the present study was to evaluate the effect of the two methods of delivery, “hands-on” vs. “hands poised”, on perineal trauma and delivery outcome in primiparous women referred to Shariati Hospital of Isfahan during 2007-2008. METHODS: In a clinical trial study, 100 low risk primiparous pregnant women were randomly assigned to two hands-on and hand-poised (hands-off) groups. In the hands-on group, this method was used to control fetal head in the second stage of labor. It means that the fingers of one hand supported fetal occiput and the other hand applied slight pressure on the head to control the delivery of the head during the crowning process. In the hands-poised group, midwife observed the parturient woman and do not touch perineum during the second labor stage while fetal head was delivering. Then, the two groups were compared in terms of perineal trauma, as well as neonatal and delivery outcome. RESULTS: Demographic characteristics of all studied women were similar in two groups. The rate of episiotomy was higher in hands-on group (84% vs. 40%, p = 0.001). The rate of postpartum hemorrhage (4th stage) was higher in hands-on group (12% vs. 4%, p = 0.04). The rate of mild and moderate postpartum pain in hands-on group was higher than hands-off group (70% vs. 58% and 29% vs. 10%, p < 0.001) but sever pain was not different in two groups. CONCLUSIONS: It seems that hands-poised method is associated with less perineal trauma, particularly regarding the lower need for episiotomy and postpartum hemorrhage. PMID:22279480

Objective to describe the victim profile and circumstances of transport accidents involving children and adolescents who were attended at a teaching hospital in the southern zone of the city of São Paulo. Methods this was an individual observational case series study among patients up to the age of 19 years who were attended at a hospital in the southern zone of the city of São Paulo, state of São Paulo, Brazil, due to traffic accidents. The files notifying suspected or confirmed cases of violence and accidents (SIVVA files) covering January to December 2012 were analyzed. Results among the 149 cases notified, 64.4% related to males and 35.6% to females. The transport accidents were predominantly among males, irrespective of age. The main injury diagnoses were superficial head trauma (24.8%) followed by multiple non-specified trauma (36.4%), in both sexes. Conclusion transport accidents among children and adolescents occurred more often among males. The main transport accidents among the children and adolescents attended as emergency cases were caused by motor vehicles and motorcycles. Among the accident victims, the largest proportion was attended because of being run over. PMID:26229833

Few cases of cervical schwannoma have been reported following head trauma. The present case, involves a schwannoma of the C2 spinal nerve mimicking post-concussion symptoms following a sport-related concussion (SRC). Case study. University of Calgary, Sport Medicine Clinic, Calgary, Alberta, Canada. We report a 28 year old, athlete who developed headache, dizziness, photophobia, and neck pain following a cycling accident. She presented nine months later to our sports clinic with persistent symptoms. She had a normal neurological examination but complained of painful neck range of motion, and exacerbation of symptoms with neck extension. On palpation, a lump was found in the right suboccipital muscles and MRI showed a T2 hyperintense mass at the C1-2 level. The patient underwent resection and histology revealed a schwannoma of the C2 nerve root. Following resection her symptoms improved, with no recurrence at 2 months follow up. Our patient's slow recovery following SRC is consistent with a schwannoma formation, which may have been precipitated by the injury itself or merely unmasked from trauma. This case illustrates the importance of a thorough physical examination and broad differential in patients presenting with worsening of symptoms after initial improvement in SRC.

The purposes of the current investigation are to evaluate the epidemiology of water sport injuries at a coastal tertiary trauma center and to determine the association of these activities with spinal column injury and to determine whether aquatic trauma injuries differ significantly from those that occur terrestrially. A retrospective review of a consecutive series of 105 patients with aquatic-based mechanisms of injury admitted to a Level II trauma center over a 3-year period, as well as a matched control cohort with terrestrial-based mechanisms of injury, was conducted. Patients were treated at a Level II trauma center from January 1, 2008, to December 31, 2010. All patients received a full trauma work-up on arrival. Patients were identified retrospectively from a prospectively collected database (N=5298). Eligible patients were identified from billing/coding data as having mechanisms of injury related to an aquatic setting. Patients were evaluated using standard trauma protocols. Spinal column and cord injury occurrence and differences between groups were reviewed. Personal watercrafts accounted for the majority of injuries (n=39). Cervical (33.3%), closed-head (25.7%), and thoracolumbar (21.9%) injuries accounted for the majority of injury types. The cervical spinal column and the spinal cord were at an increased risk of injury in the aquatic injury cohort (P<.0001). The current data show the high incidence of spinal column and cord injuries in this patient population relative to controls. Practitioners who care for trauma patients near an aquatic environment should be aware of the high prevalence of these injuries, with proper spinal cord preservation protocols in place to optimize outcome.

2011-07-01

The potential for the injury or death of a child resulting from the tip-over of a piece of household furniture or a domestic appliance has not been previously well recognized. We reviewed nine accidental deaths of young children that resulted from avoidable residential hazards and/or lapses in supervision of the children by their caregivers. The offending household items included televisions, bedroom dressers, a kitchen stove, and a lounge chair. The causes of death were mechanical asphyxia, blunt trauma, and combined blunt head trauma and asphyxia. All of the deaths could have been prevented by appropriate anchoring of the piece of furniture and/or closer supervision of the child. A thorough multidisciplinary investigation is essential in establishing the cause and manner of death in such cases and in identifying risk factors that may aid in the prevention of future childhood deaths. © 2011 American Academy of Forensic Sciences.

Traumatic orbital CSF leak

2013-01-01

Compared to the cerebrospinalfluid (CSF) leak through the nose and ear, the orbital CSF leak is a rare and underreported condition following head trauma. We present the case of a 49-year-old woman with oedematous eyelid swelling and ecchymosis after a seemingly trivial fall onto the right orbit. Apart from the above, she was clinically unremarkable. The CT scan revealed a minimally displaced fracture of the orbital roof with no emphysema or intracranial bleeding. The fractured orbital roof in combination with the oedematous eyelid swelling raised the suspicion for orbital CSF leak. The MRI of the neurocranium demonstrated a small-sized CSF fistula extending from the anterior cranial fossa to the right orbit. The patient was treated conservatively and the lid swelling resolved completely after 5 days. Although rare, orbital CSF leak needs to be included in the differential diagnosis of periorbital swelling following orbital trauma. PMID:24323381

As the popularity of longboarding increases, trauma centers are treating an increased number of high severity injuries. Current literature lacks descriptions of the types of injuries experienced by longboarders, a distinct subset of the skateboarding culture. A retrospective review of longboarding and skateboarding injury cases was conducted at a level II trauma center from January 1, 2006, through December 31, 2011. Specific injuries in addition to high injury severity factors (hospital and intensive care unit (ICU) length of stay (LOS), Injury Severity Score (ISS), patient treatment options, disposition, and outcome) were calculated to compare longboarder to skateboarder injuries. A total of 824 patients met the inclusion criteria. Skull fractures, traumatic brain injuries (TBI), and intracranial hemorrhage (ICH) were significantly more common among longboard patients than skateboarders (P < 0.0001). All patients with an ISS above 15 were longboarders. Hospital and ICU LOS in days was also significantly greater for longboarders compared with skateboarders (P < 0.0001). Of the three patients that died, each was a longboarder and each experienced a head injury. Longboard injuries account for a higher incidence rate of severe head injuries compared to skateboard injuries. Our data show that further, prospective investigation into the longboarding population demographics and injury patterns is necessary to contribute to effective injury prevention in this population.

To provide family physicians with updated, practical, evidence-based information about mild head injury (MHI) and concussion in the pediatric population. MEDLINE (1950 to February 2013), the Cochrane Database of Systematic Reviews (2005 to 2013), the Cochrane Central Register of Controlled Trials (2005 to 2013), and DARE (2005 to 2013) were searched using terms relevant to concussion and head trauma. Guidelines, position statements, articles, and original research relevant to MHI were selected. Trauma is the main cause of death in children older than 1 year of age, and within this group head trauma is the leading cause of disability and death. Nine percent of reported athletic injuries in high school students involve MHI. Family physicians need to take a focused history, perform physical and neurologic examinations, use standardized evaluation instruments (Glasgow Coma Scale; the Sport Concussion Assessment Tool, version 3; the child version of the Sport Concussion Assessment Tool; and the Balance Error Scoring System), instruct parents how to monitor their children, decide when caregivers are not an appropriately responsible resource, follow up with patients promptly, guide a safe return to play and to learning, and decide when neuropsychological testing for longer-term follow-up is required. A thorough history, physical and neurologic assessment, the use of validated tools to provide an objective framework, and periodic follow-up are the basis of family physician management of pediatric MHI.

Spontaneous closures of dural arteriovenous fistulas (dAVFs) are rare. We present spontaneous occlusion of dAVFs in 3 cases (one type IIa dAVF, one type IIb and one type III). Patients were 3 males with a mean age of 55 years (range 45-61). For two patients, the dAVF was revealed by hemorrhage. No head trauma was recorded at the interrogatory. Mean delay for spontaneous closure was 4 months (3-5 months). Review of the literature about this rare occurrence is presented and the factors that may lead to spontaneous occlusion of dAVFs are discussed. Copyright © 2012 Elsevier B.V. All rights reserved.

Background The Focused Assessment with Sonography for Trauma (FAST) exam is an important variable in many retrospective trauma studies. The purpose of this study was to devise an imputation method to overcome missing data for the FAST exam. Due to variability in patients’ injuries and trauma care, these data are unlikely to be missing completely at random (MCAR), raising concern for validity when analyses exclude patients with missing values. Methods Imputation was conducted under a less restrictive, more plausible missing at random (MAR) assumption. Patients with missing FAST exams had available data on alternate, clinically relevant elements that were strongly associated with FAST results in complete cases, especially when considered jointly. Subjects with missing data (32.7%) were divided into eight mutually exclusive groups based on selected variables that both described the injury and were associated with missing FAST values. Additional variables were selected within each group to classify missing FAST values as positive or negative, and correct FAST exam classification based on these variables was determined for patients with non-missing FAST values. Results Severe head/neck injury (odds ratio, OR=2.04), severe extremity injury (OR=4.03), severe abdominal injury (OR=1.94), no injury (OR=1.94), other abdominal injury (OR=0.47), other head/neck injury (OR=0.57) and other extremity injury (OR=0.45) groups had significant ORs for missing data; the other group odds ratio was not significant (OR=0.84). All 407 missing FAST values were imputed, with 109 classified as positive. Correct classification of non-missing FAST results using the alternate variables was 87.2%. Conclusions Purposeful imputation for missing FAST exams based on interactions among selected variables assessed by simple stratification may be a useful adjunct to sensitivity analysis in the evaluation of imputation strategies under different missing data mechanisms. This approach has the potential for widespread application in clinical and translational research and validation is warranted. Level of Evidence Level II Prognostic or Epidemiological PMID:23778515

The objectives of the present study were to describe the injury profiles of cyclists presenting to an ED and determine the risk of significant head injury associated with bicycle helmet use. This was a retrospective single trauma centre study of all adult cyclists presenting to an inner city ED and undergoing a trauma team review between January 2012 and June 2014. The outcome of interest was significant head injury defined as any head injury with an Abbreviated Injury Scale score of two or more. Variables analysed included demographic characteristics, helmet use at time of incident, location, time and the presence of intoxication. The most common body regions were upper limb injuries (57%), followed by head injuries (43%), facial injuries (30%) and lower limb injuries (24%). A lower proportion of people wearing helmets had significant head injury (17% vs 31%, P = 0.018) or facial injury (26% vs 48%, P = 0.0017) compared with non-helmet users. After adjustment for important covariates, helmet use was associated with a 70% decrease in the odds of significant head injury (odds ratio 0.34, 95% confidence interval 0.15, 0.76, P = 0.008). Head injuries were common after inner city cycling incidents. The use of helmets was associated with a reduction in significant head injury. © 2015 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Splenic artery embolization (SAE) is a common procedure in trauma patients with blunt splenic injuries. We report a case of acute ischemic stroke following orthopedic surgery in a patient with post-SAE reactive thrombocytosis. A 37-year-old woman with idiopathic thrombocytopenic purpura (ITP) suffered from multiple trauma scheduled for open reduction and internal fixation for right tibial and left radius fracture five days after SAE. The patient did not have any thromboembolic complications, although the platelet counts increased from 43 × 10/L to 568 × 10/L within two days after SAE. Surgery was completed under general anesthesia with tracheal intubation without complications. The patient complained of visual loss followed by limb weakness on the fourth and eighth hour postoperatively. Magnetic resonance imaging (MRI) of head demonstrated ischemic change over bilateral basal ganglia, and occipital areas, suggesting the diagnosis of cortical blindness. To suppress platelet count and avoid platelet hyper-aggregation, anti-platelet drug (i.e., oral aspirin 100 mg daily), hydration, and hydroxyurea (i.e., 20 mg/kg daily) were used for the treatment of reactive thrombocytosis. Although right-sided hemiparesis persisted, the patient reported mild visual recovery. She was discharged four months after SAE with active rehabilitation. Our report highlights an increased risk of acute arterial thromboembolic events in patients with reactive thrombocytosis, especially those undergoing surgery.

In whiplash studies, there may be interpretation difficulties: are post-whiplash findings, when present, a consequence of the whiplash trauma, or did they exist prior to trauma? In the Vågå headache epidemiology study (1995-1997), there was a headache history and detailed physical/neurological findings from the face/head/neck in 1838 18-65-year-old parishioners. In September 2001, four years after the Vågå study, a search through the Health Centre files divulged six cases with whiplash trauma in the intervening period. These parishioners could thus be their own controls. Two females did not develop new complaints. In the four parishioners with apparently new, subjective complaints, i.e., headache, neck pain, and a feeling of stiffness in the neck, there were corresponding findings as regards various parameters: shoulder area skin-roll test, changes in two, possible changes in two; range of motion, neck, changes in two, borderline changes in one; "features indicative of cervical abnormality" ("CF"), changes in all four; the mean, post-whiplash stage value was: 3.6+, against 1.6+ prior to accident (Vågå: only 0.93%, "CF" exceeding 3+). In the two without new complaints, the mean "CF" value was 1.0+. The number of cases is small, but the similarity of the symptoms--and signs--following whiplash injury may suggest an element of organic origin in the whiplash syndrome.

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.

To examine the association between in-hospital mortality and the BIG (composed of the base deficit [B], International normalized ratio [I], Glasgow Coma Scale [G]) score measured on arrival to the emergency department in pediatric blunt trauma patients, adjusted for pre-hospital intubation, volume administration, and presence of hypotension and head injury. We also examined the association between the BIG score and mortality in patients requiring admission to the intensive care unit (ICU). A retrospective 2001-2012 trauma database review of patients with blunt trauma ≤ 17 years old with an Injury Severity score ≥ 12. Charts were reviewed for in-hospital mortality, components of the BIG score upon arrival to the emergency department, prehospital intubation, crystalloids ≥ 20 mL/kg, presence of hypotension, head injury, and disposition. 50/621 (8%) of the study patients died. Independent mortality predictors were the BIG score (OR 11, 95% CI 6-25), prior fluid bolus (OR 3, 95% CI 1.3-9), and prior intubation (OR 8, 95% CI 2-40). The area under the receiver operating characteristic curve was 0.95 (CI 0.93-0.98), with the optimal BIG cutoff of 16. With BIG <16, death rate was 3/496 (0.006, 95% CI 0.001-0.007) vs 47/125 (0.38, 95% CI 0.15-0.7) with BIG ≥ 16, (P < .0001). In patients requiring admission to the ICU, the BIG score remained predictive of mortality (OR 14.3, 95% CI 7.3-32, P < .0001). The BIG score accurately predicts mortality in a population of North American pediatric patients with blunt trauma independent of pre-hospital interventions, presence of head injury, and hypotension, and identifies children with a high probability of survival (BIG <16). The BIG score is also associated with mortality in pediatric patients with trauma requiring admission to the ICU. Copyright © 2015 Elsevier Inc. All rights reserved.

Our knowledge about the bidirectional interactions between brain and whole organism after trauma is still limited. It was the purpose of this prospective clinical study to determine the influence of severe head trauma (SHT) as well as trauma in different anatomic injury regions on posttraumatic inflammatory mediator levels from patients with multiple injuries. Thirty-five healthy controls, 33 patients with an isolated SHT, 47 patients with multiple injuries without SHT, and 45 patients with both SHT and multiple injuries were studied. The posttraumatic plasma levels of soluble tumor necrosis factor receptors p55 and p75, interleukin (IL)-6, IL-10, and polymorphonuclear neutrophil (PMN) elastase were monitored using enzyme-linked immunosorbent assay technique. The influence of head injuries as well as thorax, abdomen, and extremity injuries on the mediator release from patients with multiple injuries was investigated by multivariate linear regression models. The soluble tumor necrosis factor receptor p55/p75 ratio was significantly elevated within 3 hours of trauma in all three injury groups and returned to reference ratios after 12 hours. The lowest increase was found in patients suffering from an isolated SHT. Lowest mediator levels in this patient population were also found for IL-6, IL-10, and PMN elastase during the first 36 hours after trauma. Additional injuries to the head, thorax, abdomen, and extremity modulated mediator levels to a different degree. No specific effect was found for SHT when compared with other injury groups. Thorax injuries caused the quickest rise in mediator levels, whereas abdominal injuries significantly increased PMN elastase levels 12 to 24 hours after trauma. Traumatic injuries cause the liberation of various mediators, without any specific association between anatomic injury pattern and the pattern of mediator release.

The role of fever in trauma patients remains unclear. Fever occurs as a response to release of cytokines and prostaglandins by white blood cells. Many factors, including trauma, can trigger release of these factors. To determine whether (1) fever in the first 48 hours is related to a favorable outcome in trauma patients and (2) fever is more common in patients with head trauma. Retrospective study of trauma patients admitted to the intensive care unit for at least 2 days. Data were analyzed by using multivariate analysis. Of 162 patients studied, 40% had fever during the first 48 hours. Febrile patients had higher mortality rates than did afebrile patients. When adjusted for severity of injuries, fever did not correlate with mortality. Neither the incidence of fever in the first 48 hours after admission to the intensive care unit nor the number of days febrile in the unit differed between patients with and patients without head trauma (traumatic brain injury). About 70% of febrile patients did not have a source found for their fever. Febrile patients without an identified source of infection had lower peak white blood cell counts, lower maximum body temperature, and higher minimum platelet counts than did febrile patients who had an infectious source identified. The most common infection was pneumonia. No relationship was found between the presence of fever during the first 48 hours and mortality. Patients with traumatic brain injury did not have a higher incidence of fever than did patients without traumatic brain injury. About 30% of febrile patients had an identifiable source of infection. Further studies are needed to understand the origin and role of fever in trauma patients. ©2015 American Association of Critical-Care Nurses.

Background Occipital neuralgia (ON) is a condition characterized by a paroxysmal stabbing pain in the area of the greater or lesser occipital nerves; it is usually regarded by clinicians as idiopathic. Some have suggested that ON can be induced by trauma or injury of the occipital nerves or their roots, but tumor has rarely been reported as a cause of ON. Case Report We report herein a case of foramen magnum meningioma in a 55-year-old woman who presented with ON triggered by head motion as the only symptom without any signs of myelopathy. Conclusions This case indicates that it is important to consider the underlying causes of ON. Precise neurologic and radiological evaluations such as cervical spine magnetic resonance imaging are needed. PMID:20076803

2018-04-01

Traumatic brain injury (TBI) is a very common entity that leads to numerous fatalities all over the world. Therefore, forensic pathologists are in desperate need of supplemental methodological tools for the diagnosis of TBI in everyday practice besides the standard autopsy. The present study determined post-mortem neuron specific enolase (NSE) and S100 calcium-binding protein B (S100B) levels as biological markers of an underlying TBI in autopsy cases. Paired serum and CSF samples of 92 fatalities were collected throughout routine autopsies. Afterwards, the marker levels were assessed using commercially available immunoassays (ECLIA, Roche Diagnostics). For statistical analysis, we compared the TBI cases to three control groups (sudden natural death by acute myocardial infarction, traumatic death without impact on the head, cerebral hypoxia). Moreover, the TBI cases were subdivided according to their survival time of the trauma. Brain specimens have been collected and stained immunohistochemically against the aforementioned proteins to illustrate their typical cellular staining patterns with an underlying TBI compared to non-TBI fatalities. CSF NSE and S100B levels were elevated after TBI compared to all control groups (p < 0.001). Although this finding can already be investigated among the TBI cases dying immediately subsequent to the trauma, the marker levels in CSF increase with longer survival times until a peak level within the first three days after trauma. There is a strong correlation between both marker levels in CSF (r = 0.67). The presence or absence of cerebral tissue contusion following the initial trauma does not seem to affect the CSF levels of both proteins (p > 0.05). Post-mortem serum levels of both proteins were not elevated in TBI cases compared to controls (p > 0.05). Former elaborated cut-off values in CSF were confirmed and were only exceeded when a TBI survival time of at least 30 min was reached. The present results report that post-mortem NSE and S100B CSF levels are significantly elevated subsequent to a fatal TBI. Copyright © 2018 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Fluid dynamics vascular theory of brain and inner-ear function in traumatic brain injury: a translational hypothesis for diagnosis and treatment.

PubMed

Shulman, Abraham; Strashun, Arnold M

2009-01-01

It is hypothesized that in all traumatic brain injury (TBI) patients with a clinical history of closed or penetrating head injury, the initial head trauma is associated with a vibratory sensation and noise exposure, with resultant alteration in vascular supply to the structures and contents of the fluid compartments of brain and ear (i.e., the fluid dynamics vascular theory of brain-inner-ear function [FDVTBE]). The primary etiology-head trauma-results in an initial fluctuation, interference, or interaction in the normal fluid dynamics between brain and labyrinth of the inner ear, with a resultant clinical diversity of complaints varying in time of onset and severity. Normal function of the brain and ear is a reflection of a normal state of homeostasis between the fluid compartments in the brain of cerebrospinal fluid and perilymph-endolymph in the labyrinth of the ear. The normal homeostasis in the structures and contents between the two fluid compartment systems--intracerebral and intralabyrinthine--is controlled by mechanisms involved in the maintenance of normal pressures, water and electrolyte content, and neurotransmitter activities. The initial pathophysiology (a reflection of an alteration in the vascular supply to the brain-ear) is hypothesized to be an initial acute inflammatory response, persistence of which results in ischemia and an irreversible alteration in the involved neural substrates of brain-ear. Clinically, a chronic multisymptom complex becomes manifest. The multisymptom complex, individual for each TBI patient regardless of the diagnostic TBI category (i.e., mild, moderate, or severe), initially reflects processes of inflammation and ischemia which, in brain, result in brain volume loss identified as neurodegeneration and hydrocephalus ex vacuo or an alteration in cerebrospinal fluid production (i.e., pseudotumor cerebri) and, in ear, secondary endolymphatic hydrops with associated cochleovestibular complaints of hearing loss, tinnitus, vertigo, ear blockage, and hyperacusis. The FDVTBE integrates and translates a neurovascular hypothesis for Alzheimer's disease to TBI. This study presents an FDVTBE hypothesis of TBI to explain the clinical association of head trauma (TBI) and central nervous system neurodegeneration with multisensory complaints, highlighted by and focusing on cochleovestibular complaints. A clinical case report, previously published for demonstration of the cerebrovascular medical significance of a particular type of tinnitus, and evidence-based basic science and clinical medicine are cited to provide objective evidence in support and demonstration of the FDVTBE.

Immunostaining for beta-amyloid precursor protein (APP) is recognized as an effective tool for detecting traumatic axonal injury, but it also detects axonal injury due to ischemic or other metabolic causes. Previously, we reported two different patterns of APP staining: labeled axons oriented along with white matter bundles (pattern 1) and labeled axons scattered irregularly (pattern 2) (Hayashi et al. (Leg Med (Tokyo) 11:S171-173, 2009). In this study, we investigated whether these two patterns are consistent with patterns of trauma and hypoxic brain damage, respectively. Sections of the corpus callosum from 44 cases of blunt head injury and equivalent control tissue were immunostained for APP. APP was detected in injured axons such as axonal bulbs and varicose axons in 24 of the 44 cases of head injuries that also survived for three or more hours after injury. In 21 of the 24 APP-positive cases, pattern 1 alone was observed in 14 cases, pattern 2 alone was not observed in any cases, and both patterns 1 and 2 were detected in 7 cases. APP-labeled injured axons were detected in 3 of the 44 control cases, all of which were pattern 2. These results suggest that pattern 1 indicates traumatic axonal injury, while pattern 2 results from hypoxic insult. These patterns may be useful to differentiate between traumatic and nontraumatic axonal injuries.

Trauma is an increasingly important cause of disease globally. Half of this trauma is from road traffic injuries with motorcycles contributing 21-58%. Low protective gear use, lack of regulation and weak traffic law enforcement contribute to unsafe nature of commercial motorcycles also known as "boda boda" in Uganda. To determine the prevalence of protective gear use, the occurrence of head injury and the relationship between the two among commercial motorcycle riders in Kampala. Following ethical approval we recruited consecutive consenting participants to this analytical cross-sectional study. Data was collected using pretested interviewer administered questionnaires, double entered in Epidata and analyzed with STATA. Proportions and means were used to summarize data. Odds ratios were calculated for association between wearing helmets and occurrence and severity of head injury. All 328 participants recruited were male. Of these, 18.6% used Protective gear and 71.1 % sustained head injury. Helmets protected users from head injury (OR 0.43, 95% CI, 0.23-0.8) and significantly reduced its severity when it occurred. Protective gear use was low, with high occurrence of head injury among commercial motorcycle riders in Uganda. More effective strategies are needed to promote protective gear use among Uganda's commercial motorcycle riders.

The pituitary gland plays a key role in hormonal regulation in the organism, contributing to maintenance of balance of basic vital functions. To emphasise the need for assessment of pituitary function after head injury, as correct diagnosis and hormone replacement therapy prove to be a life-saving therapy accelerating the recovery process. A healthy, normally developing 9-year-old girl, a child of young and healthy parents, was struck by a falling tree. The results of severe head trauma included adrenal crisis, hypothyroidism, and diabetes insipidus as manifestations of damage to the anterior and posterior pituitary gland. Administration of hormone replacement therapy, i.e. hydrocortisone, L-thyroxine, and desmopressin greatly improved the patient´s condition and facilitated effective rehabilitation. Determination of pituitary hormones in children after severe head injury should be an important part of diagnosis allowing identification of an early stage of acute hypopituitarism and acceleration of recovery through hormone replacement therapy.

Disturbed jaw behavior in whiplash-associated disorders during rhythmic jaw movements.

Häggman-Henrikson, B; Zafar, H; Eriksson, P-O

2002-11-01

As shown previously, "functional jaw movements" are the result of coordinated activation of jaw as well as neck muscles, leading to simultaneous movements in the temporomandibular, atlanto-occipital, and cervical spine joints. In this study, the effect of neck trauma on natural jaw function was evaluated in 12 individuals suffering from whiplash-associated disorders (WAD). Spatiotemporal characteristics of mandibular and concomitant head movements were evaluated for three different modes of rhythmic jaw activities: self-paced continuous maximal jaw-opening/-closing movements, paced continuous maximal jaw-opening/-closing movements at 50 cycles/minute, and unilateral chewing. Compared with healthy subjects, the WAD group showed smaller magnitude and altered coordination pattern (a change in temporal relations) of mandibular and head movements. In conclusion, these results show that neck trauma can derange integrated jaw and neck behavior, and underline the functional coupling between the jaw and head-neck motor systems.

Background Olfactory disorders are common complaints in ENT clinics. We investigated causes and relevant features of olfactory disorders and the need for gustatory testing in patients with olfactory dysfunction. Material/Methods A total of 140 patients seeking medical consultations were enrolled. All patients were asked about their olfactory disorders in a structured interview of medical history and underwent thorough otolaryngologic examinations and imaging of the head. Results Causes of olfactory disorders were classified as: upper respiratory tract infection (URTI), sinonasal diseases (NSD), head trauma, idiopathic, endoscopic sinus surgery, congenital anosmia, and other causes. Each of the various causes of olfactory dysfunction had its own distinct clinical features. Nineteen of 54 patients whose gustation was assessed had gustatory disorders. Conclusions The leading causes of olfactory dysfunction were URTI, NSD, head trauma, and idiopathic causes. Gustatory disorders were fairly common in patients with olfactory dysfunction. High priority should be given to complaints of olfactory disorders. PMID:23748259

Reports on penetrating ballistic head injuries in the literature are dominated by case studies of suicides; the penetrating ammunition usually being .22 rimfire or shotgun. The dominating cause of injuries in modern warfare is fragmentation and hence, this is the primary threat that military helmets protect the brain from. When helmets are perforated, this is usually by bullets. In combat, 20% of penetrating injuries occur to the head and its wounding accounts for 50% of combat deaths. A number of head simulants are described in the academic literature, in ballistic test methods for helmets (including measurement of behind helmet blunt trauma, BHBT) and in the 'open' and 'closed' government literature of several nations. The majority of these models are not anatomically correct and are not assessed with high-velocity rifle ammunition. In this article, an anatomically correct 'skull' (manufactured from polyurethane) and 'brain' (manufactured from 10%, by mass, gelatine) model for use in military wound ballistic studies is described. Filling the cranium completely with gelatine resulted in a similar 'skull' fracture pattern as an anatomically correct 'brain' combined with a representation of cerebrospinal fluid. In particular, posterior cranial fossa and occipital fractures and brain ejection were observed. This pattern of injury compared favourably to reported case studies of actual incidents in the literature.

Objectives To evaluate the impact of the partial repeal of Michigan’s universal motorcycle helmet law on helmet use, fatalities, and head injuries. Methods We compared helmet use rates and motorcycle crash fatality risk for the 12 months before and after the April 13, 2012, repeal with a statewide police-reported crash data set. We linked police-reported crashes to injured riders in a statewide trauma registry. We compared head injury before and after the repeal. Regression examined the effect of helmet use on fatality and head injury risk. Results Helmet use decreased in crash (93.2% vs 70.8%; P < .001) and trauma data (91.1% vs 66.2%; P < .001) after the repeal. Although fatalities did not change overall (3.3% vs 3.2%; P = .87), head injuries (43.4% vs 49.6%; P < .05) and neurosurgical intervention increased (3.7% vs 6.5%; P < .05). Male gender (adjusted odds ratio [AOR] = 1.65), helmet nonuse (AOR = 1.84), alcohol intoxication (AOR = 11.31), intersection crashes (AOR = 1.62), and crashes at higher speed limits (AOR = 1.04) increased fatality risk. Helmet nonuse (AOR = 2.31) and alcohol intoxication (AOR = 2.81) increased odds of head injury. Conclusions Michigan’s helmet law repeal resulted in a 24% to 27% helmet use decline among riders in crashes and a 14% increase in head injury. PMID:27854530

Injury is recognised as a frequent cause of preventable mortality and morbidity; however, incidence estimates focusing only on the extent of mortality and major trauma may seriously underestimate the magnitude of the total injury burden. There currently exists a paucity of information regarding minor trauma, and the aim of this study was to increase awareness of the contribution of minor trauma cases to the total burden of injury. The demographics, injury details, acute care factors and outcomes of both minor trauma cases and major trauma cases were evaluated using data from the state-wide trauma registry in Queensland, Australia, from 2005 to 2010. The impact of changes in Abbreviated Injury Scale (AIS) versions on the classification of minor and major injury cases was also assessed. Over the 6-year period, minor cases [Injury Severity Score (ISS) ≤ 12] accounted for almost 90% of all trauma included on the Queensland Trauma Registry (QTR). These cases utilised more than half a million acute care bed days, underwent more than 66,500 operations, and accounted for more than 48,000 patient transport episodes via road ambulance, fixed wing aircraft, or helicopter. Furthermore, more than 5800 minor trauma cases utilised in-hospital rehabilitation services; almost 3000 were admitted to an ICU; and more than 20,000 were admitted to hospital for greater than one week. When using the contemporary criteria for classifying trauma (AIS 08), the proportion of cases classified as minor trauma (87.7%) and major trauma (12.3%) were similar to the proportion using the traditional criteria for AIS90 (87.9% and 12.1%, respectively). This evaluation of minor trauma cases admitted to public hospitals in Queensland detected high levels of demand placed on trauma system resources in terms of acute care bed days, operations, ICU admissions, in-hospital rehabilitation services and patient transportation, and which are all associated with high cost. These data convincingly demonstrate the significant burden of injury imposed by minor trauma cases serious enough to be admitted to hospital. Copyright © 2014 Elsevier Ltd. All rights reserved.

Few studies have addressed the relationship between dementia and crime. We conducted a study of persons who got a primary or secondary diagnosis of dementia or cognitive disorder in a forensic psychiatric examination. In Sweden, annually about 500 forensic psychiatric examinations are carried out. All cases from 2008 to 2010 with the diagnoses dementia or cognitive disorder were selected from the database of the Swedish National Board of Forensic Medicine. Out of 1471 cases, there were 54 cases of dementia or cognitive disorder. Case files were scrutinized and 17 cases of dementia and 4 cases of cognitive disorder likely to get a dementia diagnosis in a clinical setting were identified and further studied. There were 18 men and 3 women; Median age 66 (n = 21; Range 35-77) years of age. Eleven men but no women had a previous criminal record. There were a total of 38 crimes, mostly violent, committed by the 21 persons. The crimes were of impulsive rather that pre-meditated character. According to the forensic psychiatric diagnoses, dementia was caused by cerebrovascular disorder (n = 4), alcohol or substance abuse (n = 3), cerebral haemorrhage and alcohol (n = 1), head trauma and alcohol (n = 2), Alzheimer's disease (n = 2), Parkinson's disease (n = 1), herpes encephalitis (n = 1) and unspecified (3). Out of four persons diagnosed with cognitive disorder, one also had delusional disorder and another one psychotic disorder and alcohol dependence. An alcohol-related diagnosis was established in ten cases. There were only two cases of Dementia of Alzheimer's type, one of whom also had alcohol intoxication. None was diagnosed with a personality disorder. All but one had a history of somatic or psychiatric comorbidity like head traumas, stroke, other cardio-vascular disorders, epilepsy, depression, psychotic disorders and suicide attempts. In this very ill group, the suggested verdict was probation in one case and different forms of care in the remaining 20 cases instead of prison. Few cases of dementia or cognitive disorder were identified by forensic psychiatric examinations. All but one suffered from a variety of serious mental and medical conditions affecting the brain. Alcohol abuse was prevalent.

Improving the sensitivity and specificity of the abbreviated injury scale coding system.

The Abbreviated Injury Scale with Epidemiologic Modifications (AIS 85-EM) was developed to make it possible to code information about anatomic injury types and locations that, although generally available from medical records, is not codable under the standard Abbreviated Injury Scale, published by the American Association for Automotive Medicine in 1985 (AIS 85). In a population-based sample of 3,223 motor vehicle trauma cases, 68 percent of the patients had one or more injuries that were coded to the AIS 85 body region nonspecific category external. When the same patients' injuries were coded using the AIS 85-EM coding procedure, only 15 percent of the patients had injuries that could not be coded to a specific body region. With AIS 85-EM, the proportion of codable head injury cases increased from 16 percent to 37 percent, thereby improving the potential for identifying cases with head and threshold brain injury. The data suggest that body region coding of all injuries is necessary to draw valid and reliable conclusions about changes in injury patterns and their sequelae. The increased specificity of body region coding improves assessments of the efficacy of injury intervention strategies and countermeasure programs using epidemiologic methodology. PMID:2116633

Data suggests that clinicians, when evaluating pediatric patients with blunt head trauma, may be over-ordering head computed tomography. Prior decision instruments aimed at aiding clinicians in safely forgoing CTs may be paradoxically increasing CT utilization. This study evaluated a novel decision instrument that aims for high sensitivity while also improving specificity over prior instruments. We conducted a planned secondary analysis of the NEXUS Head CT decision instrument (DI) among patients less than 18 years old. The rule required patients satisfy seven criteria to achieve "low-risk" classification. Patients were assigned "high risk" status if they fail to meet one or more criteria. Our primary outcome was the ability of the rule to identify all patients requiring neurosurgical intervention. The study enrolled 1,018 blunt head injury pediatric patients. The DI assigned high-risk status to 27 of 27 patients requiring neurosurgical intervention (sensitivity, 100.0% [95% confidence interval [CI]: 87.2% - 100%]). The instrument assigned low-risk status to 330 of 991 patients who did not require neurosurgical intervention (specificity, 33.3% [95% CI: 30.3% - 36.3%]). None of the 991 low-risk patients required neurosurgical intervention (NPV, 100% [95% CI: 99.6% - 100%]). The DI correctly assigned high-risk status to 48 of the 49 patients with significant intracranial injuries, yielding a sensitivity of 98.0% (95% CI: 89.1% - 99.9%). The instrument assigned low-risk status to 329 of 969 patients who did not have significant injuries to yield a specificity of 34.0% (95% CI: 31.0% - 37.0%). Significant injuries were absent in 329 of the 330 patients assigned low-risk status to yield a NPV of 99.7% (95% CI: 98.3% - 100%). The Pediatric NEXUS Head CT DI reliably identifies blunt trauma patients who require head CT imaging, and could significantly reduce the use of CT imaging This article is protected by copyright.

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.

Techniques for assisting difficult delivery at caesarean section.

PubMed

Waterfall, Heather; Grivell, Rosalie M; Dodd, Jodie M

2016-01-31

Caesarean section involves making an incision in the woman's abdomen and cutting through the uterine muscle. The baby is then delivered through that incision. Difficult caesarean birth may result in injury for the infant or complications for the mother. Methods to assist with delivery include vacuum or forceps extraction or manual delivery utilising fundal pressure. Medication that relaxes the uterus (tocolytic medication) may facilitate the birth of the baby at caesarean section. Delivery of the impacted head after prolonged obstructed labour can be associated with significant maternal and neonatal complication; to facilitate delivery of the head the surgeon may utilise either reverse breech extraction or head pushing. To compare the use of tocolysis (routine or selective use) with no use of tocolysis or placebo and to compare different extraction methods at the time of caesarean section for outcomes of infant birth trauma, maternal complications (particularly postpartum haemorrhage requiring blood transfusion), and long-term measures of infant and childhood morbidity. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 September 2015) and reference lists of retrieved studies. All published, unpublished, and ongoing randomised controlled trials comparing the use of tocolytic agents (routine or selective) at caesarean section versus no use of tocolytic or placebo at caesarean section to facilitate the birth of the baby. Use of instrument versus manual delivery to facilitate birth of the baby. Reverse breech extraction versus head pushing to facilitate delivery of the deeply impacted fetal head. Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. Seven randomised controlled trials, involving 582 women undergoing caesarean section were included in this review. The risk of bias of included trials was variable, with some trials not adequately describing allocation or randomisation.Three comparisons were included. 1. Tocolysis versus no tocolysisA single randomised trial involving 97 women was identified and included in the review. Birth trauma was not reported. There were no cases of any maternal side-effect reported in either the nitroglycerin or the placebo group. No other maternal and infant health outcomes were reported. 2. Reverse breech extraction versus head push for the deeply impacted head at full dilation at caesarean section Four randomised trials involving 357 women were identified and included in the review. The primary outcome of birth trauma was reported by three trials and there was no difference between reverse breech extraction and head push for this rare outcome (three studies, 239 women, risk ratio (RR) 1.55, 95% confidence interval (CI) 0.42 to 5.73). Secondary outcomes including endometritis rate (three studies, 285 women, average RR 0.52, 95% CI 0.26 to 1.05, Tau I² = 0.22, I² = 56%), extension of uterine incision (four studies, 357 women, average RR 0.23, 95% CI 0.13 to 0.40), mean blood loss (three studies, 298 women, mean difference (MD) -294.92, 95% CI -493.25 to -96.59; I² = 98%) and neonatal intensive care unit (NICU)/special care nursery (SCN) admission (two studies, 226 babies, average RR 0.53, 95% CI 0.23 to 1.22, Tau I² = 0.27, I² = 74%) were decreased with reverse breech extraction. No differences were observed between groups for many of the other secondary outcomes reported (blood loss > 500 mL; blood transfusion; wound infection; mean hospital stay; average Apgar score).There was significant heterogeneity between the trials for the outcomes mean blood loss, operative time and mean hospital stay, making comparison difficult. However the operation duration was significantly shorter for reverse breech extraction, which may correspond with ease of delivery and therefore, the amount of tissue trauma and therefore, significantly less blood loss. Given the heterogeneity, we cannot define the amount of difference in blood loss, operative time or hospital stay however. 3. Instrument (vacuum or forceps) versus manual extraction at elective caesarean section Two randomised trials involving 128 women were identified and included in the review. Only one trial reported maternal and infant health outcomes as prespecified in this review. This trial reported birth trauma as an outcome but there were no instances of birth trauma in either comparison group. There were no differences found in mean fall in haemoglobin (Hb) between groups (one study, 44 women, MD 0.03, 95% CI -0.53 to 0.59), or in uterine incision extension (one study, 44 women, RR 0.70, 95% CI 0.13 to 3.73). There is currently insufficient information available from randomised trials to support or refute the routine or selective use of tocolytic agents or instrument to facilitate infant birth at the time of difficult caesarean section. There is limited evidence that reverse breech extraction may improve maternal and fetal outcomes, though there was no difference in primary outcome of infant birth trauma. Further randomised controlled trials are needed to answer these questions.

To accurately assess the mechanism, type and severity of injury in Iranian multiple trauma patients of a trauma center. Patients with multiple traumas referring to the emergency department of Hasheminejad University Hospital in Mashhad, Iran, entered this cross sectional study from March 2013 to December 2013. All the patients with injury severity score (ISS) > 9 were included in this study. Data analysis was performed by SPSS software (Version 11.5) and P values less than 0.05 were considered as significant differences. Among the 6306 hospitalized trauma patients during this period, 148 had ISS>9. The male female ratio was 80%. The mean age of the patients was (33.5 ± 19.3) years. And 71% of the patients were younger than 44 years old. There were 19 (13%) deaths from which 68.5% were older than 44 years old. The mean transfer time from the injury scene to hospital was (55 ± 26) minutes. The most frequent mechanisms of injury were motorcycle crashes and falling from height, which together included 66.2% of all the injuries. A total of 84% of hospital deaths occurred after the first 24 h of hospitalization. Head and neck were the most common body injured areas with a prevalence of 111 cases (75%). Motorcycle crashes have high frequency in Iran. Since most victims are young males, injury prevention strategies should be considered to reduce the burden of injuries.

The authors describe two male patients with prolactinomas which were incidentally found either during the course of a complete work up for headache or after minor head trauma. Since these tumours were located mainly in the sphenoid bone and did not show any upward growth to the suprasellar region, they were initially thought to be a primary skull base tumour; however, the serum prolactin levels of these patients were 1,179 ng/ml and 3,260 ng/ml, respectively. The authors thus emphasise the need to recognise this peculiar infrasellar growth pattern of prolactinoma. Copyright 2001 Harcourt Publishers Ltd.

The face plays a central role in interpersonal communication and aesthetic perception. Moreover, due to the heavy dependence of ocular function on lid anatomy, the treatment of periocular injuries, particularly those involving soft tissue loss, requires profound knowledge of both anatomy and reconstructive plastic surgery. Numerous surgical procedures are described in the literature. The aim of these procedures is to achieve an optimal functional and aesthetic result according to injury localization and extent. Against this background, treating eyelid injuries presents certain challenges. Close collaboration between all areas of head surgery is required particularly in the case of large defects.

Fat embolism syndrome is associated with respiratory failure, hypoxia, petechial rash, pyrexia and altered mental state. Signs and symptoms usually begin within 12-72 h after trauma. The pathophysiology, differential diagnosis and therapeutic options of fat embolism syndrome are described and the case of a 29-year-old motorcyclist with fractures of the lower extremities, coma and respiratory failure 24-36 h after an accident is reported. Based on the clinical signs and course, fat embolism syndrome was suspected which was substantiated by ophthalmic fundoscopy and magnetic resonance imaging of the head.

Venous air embolism occurs when air enters the venous system. The main causes of venous air embolism include medical procedures, neck and head trauma, and injuries of the genitals. Self-induced suicidal (and intentional) air embolism is extremely rare. The authors report a rare case of a suicidal air embolism committed using a self-made tool composed of a plastic bottle and an infusion set, injecting nearly 2000 mL of air into the cubital vein. The toxicological analysis suggested that midazolam, together with air, was also injected into the circulation using the same bottle and infusion set. © 2016 American Academy of Forensic Sciences.

2010-09-01

Resident duty hour restriction was instituted to improve patient safety, but actual impact on patient care is unclear. We sought to determine the effect of duty hour restriction on trauma outcomes in Level I trauma centers (TCs; surgery residency programs) versus Level II TCs (those with no surgery residency programs) within the state of Pennsylvania, using noninferiority as our hypothesis testing. Outcomes (mortality and length of stay [LOS]) were compared in Level II TCs without surgery residencies (n = 7) with Level I TCs (with surgery residencies; n = 14) PRE80 (2001-2003) and POST80 (2004-2007). The subcategories of critically injured patients, Injury Severity Score (ISS) >15, ISS >25, Trauma and Injury Severity Score (TRISS) ≤ 50, Abbreviated Injury Scale (AIS) head/chest/abdomen score >3, age >65 years, mechanism, and shock, functioned as outcome predictors. There was a decrease in mortality overall PRE80 to POST80 for Level I and II TCs. There was a decrease in mortality in Level I TCs POST80 in ISS >15 (16.5% vs. 14.8%, p = 0.0001), AIS (head) score >3 (20.8% vs. 17.8%, p < 0.0001), age >65 years (12.2% vs. 10.7%, p = 0.0013), and blunt mechanism (5.2% vs. 4.6%, p = 0.0004). LOS was reduced in ISS >15, AIS (head) score >3, age >65 years, and penetrating mechanism in Level I TCs POST80. A similar but more profound decrease was also seen in Level II TCs PRE80 and POST80 (ISS >15, 25; AIS (head) score; shock; blunt mechanism; and TRISS ≤ 50). Testing for inhomogeneity identified less-severely injured patients at Level II TCs POST80 compared with Level I TCs in certain subcategories (ISS >15, 25; AIS (head) score; shock; blunt mechanism; and TRISS ≤ 50) regarding mortality and LOS (TRISS >50%). Decreases in mortality and LOS during the study periods were likely not related to resident work hour restriction but rather to overall improvement in outcomes seen at Level II (no residents) and Level I (residents) TCs. Resident work hour restrictions had no discernible effect on patient care (noninferiority).

To compare the radiographic outcomes of 2 widely used side loading, press fit, RHA implants used to reconstruct complex elbow trauma. Retrospective cohort study. Level-1 Academic trauma center. Patients undergoing RHA. Cohort 1 received Synthes Radial Head Prosthesis. Cohort 2 received Biomet ExploR Radial Head Replacement. Radial neck dilatory remodeling. Eighty-two subjects were included in final analysis, 63 from the Biomet Cohort, and 19 from Synthes cohort. Demographic and injury characteristics were similar among cohorts. Radial neck dilatory remodeling as well as periprosthetic radiographic lucency were seen significantly more frequently and to a significantly greater degree in the Synthes cohort. The average percentage of dilatory remodeling of the Synthes cohort was 34.9% and that of the Biomet cohort was 2.7%. There were no differences in rates of revision surgery. Our study demonstrates significant radiographic differences between 2 frequently used RHA implants. Radial neck dilatory remodeling is a common, rapidly progressive, and dramatic finding frequently seen with the Synthes Radial Head Prosthesis. Therapeutic Level III.

Complex regional pain syndrome (CRPS) is a chronic condition that usually affects extremities, such as the arms or legs. It is characterized by intense pain, swelling, redness, hypersensitivity in a region not defined by a single peripheral nerve and additional sudomotor effects, such as excessive sweating. The clinical criteria for the diagnosis of sympathetically maintained pain as outlined by the International Association for the Study of Pain include: Onset following an initiating noxious event (CRPS-type I) or nerve injury (CRPS-type II). Spontaneous allodynia that is not limited to peripheral nerve distribution and is not proportionate to the inciting event; abnormal sudomotor activity, skin blood flow abnormality, edema, other autonomic symptoms; and exclusion of other conditions that may otherwise contribute to the extent of the symptoms. Only 13 cases of CRPS involving sympathetically maintained pain in the head and neck region have been described, and all reported trauma as the identifiable etiologic factor. The case presented here is another occurrence of sympathetically maintained pain in the head and neck region, but without nerve injury as a clear initiating factor.

Microvascular free tissue transfer (FTT) is an increasingly used method of reconstruction for traumatic defects of the head and neck. We describe the immediate management, FTT reconstruction techniques, and outcomes of 6 individuals who sustained maxillofacial gunshot trauma and were treated at a single tertiary-care level I trauma center. All 6 patients were white men with a mean age of 33 years. The mandible, nose, and orbital contents were the most frequently affected critical structures. All patients initially underwent primary wound debridement and tracheostomy, with concurrent maxillomandibular wire fixation and/or midface or mandible plate fixation in 5 patients. The mean time from injury to definitive FTT was 38 days. Five patients underwent fibula osteocutaneous FTT and 1 underwent radial forearm fasciocutaneous FTT. One patient also underwent concurrent local tissue rearrangement and pedicled flap surgery for nasal reconstruction. The mean hospital length of stay after FTT was 6 days. All FTT survived without necrosis. Oral incompetence and poor cosmesis from undesirable scarring patterns were the most common long-term complications. In summary, successful reconstruction of head and neck defects caused by gunshot trauma begins with airway stabilization, wound management, and bony fracture reduction and fixation. Definitive microvascular FTT is a useful method of repairing traumatic head and neck defects, although long-term functional and cosmetic complications may still occur.

Drowning, a common cause of death in the pediatric population, is a potentially large donor pool for OLT. Anecdotally, transplant centers have deemed these organs high risk over concerns for infection and graft dysfunction. We theorized drowned donor liver allografts do not portend worse outcomes and therefore should not be excluded from the donation pool. We reviewed our single-center experience of pediatric OLTs between 1988 and 2015 and identified 33 drowned donor recipients. These OLTs were matched 1:2 to head trauma donor OLTs from our center. A chart review assessed postoperative peak AST and ALT, incidence of HAT, graft and recipient survival. Recipient survival at one year between patients with drowned donor vs head trauma donor allografts was not statistically significant (94% vs 97%, P=.63). HAT incidence was 6.1% in the drowned donor group vs 7.6% in the control group (P=.78). Mean postoperative peak AST and ALT was 683 U/L and 450 U/L for drowned donors vs 1119 U/L and 828 U/L in the matched cohort. These results suggest drowned donor liver allografts do not portend worse outcomes in comparison with those procured from head trauma donors. © 2017 John Wiley & Sons A/S.

Hospital readmission is a significant contributor to increasing health care use related to caring for older trauma patients. This study was undertaken with the following aims: determine the proportion of older adult trauma patients who experience unplanned readmission, as well as risk factors for these readmissions and identify the most common readmission diagnoses among these patients. We conducted a retrospective cohort study of trauma patients age 55 years and older who survived their hospitalization at a statewide trauma center between 2009 and 2010. Linking 3 statewide databases, nonelective readmission rates were calculated for 30 days, 6 months, and 1 year after index discharge. Competing risk regression was used to determine risk factors for readmission and account for the competing risk of dying without first being readmitted. Subhazard ratios (SHR) are reported, indicating the relative risk of readmission by 30 days, 6 months, and 1 year. The cumulative readmission rates for the 14,536 participants were 7.9%, 18.9%, and 25.2% at 30 days, 6 months, and 1 year, respectively. In multivariable models, the strongest risk factors for readmission at 1 year (based on magnitude of SHR) were severe head injury (adjusted SHR = 1.47; 95% CI, 1.24-1.73) and disposition to a skilled nursing facility (SHR = 1.54; 95% CI, 1.39-1.71). The diagnoses most commonly associated with readmission were atrial fibrillation, anemia, and congestive heart failure. In this statewide study, unplanned readmissions after older adult trauma occurred frequently up to 1 year after discharge, particularly for patients who sustained severe head trauma and who could not be discharged home independently. Examining common readmission diagnoses might inform the development of interventions to prevent unplanned readmissions. Copyright © 2015 American College of Surgeons. All rights reserved.

We sought to validate National Emergency X-Radiography Utilizations Study low-risk cervical spine (C spine) criteria in a geriatric trauma population. We sought to determine whether patients' own baseline mental status (MS) could substitute for Glasgow Coma Scale (GCS) to meet the criteria "normal alertness." We further sought to refine the definition of "distracting injury." This is a retrospective review of geriatric fall patients presenting to a level 1 trauma center and triaged to the trauma bay. We queried our database from 2008 to 2013. Abstractors recorded GCS, deviation from baseline MS, midline neck tenderness, intoxication, focal deficit, signs of trauma, and presence of other injury. Patients were considered at baseline MS if specific documentation was present on the chart, or if their GCS was 15. Six hundred sixty elderly fall patients were trauma alerts during the study period. Seventeen were excluded for incomplete records/death before imaging, leaving 647. The median age was 81 (interquartile range, 74-87). Fifty patients (8.0%) had C spine or cord injury. Two hundred ninety-four (44.5%) had baseline MS (including GCS 13-15), no spine tenderness, no intoxication, and no focal neurologic deficit. Of these, 18 had C-spine injury. Using physical findings of head trauma as the only "distracting injury," no injury would have been missed (sensitivity, 100% [confidence interval, 91.1-100]; specificity, 14.2%). Our study suggests that National Emergency X-Radiography Utilizations Study can be safely applied in elderly fall patients who are at their personal baseline MS. Furthermore, our data support a more narrow definition of distracting injury to include only patients with signs of trauma to the head. Copyright © 2015 Elsevier Inc. All rights reserved.

[Avascular necrosis of the femoral head in a patient with severe aplastic anaemia].

Avascular necrosis (AVN) is a pathological condition associated with numerous processes. Most frequent causes of ischaemia of the femoral head include trauma, corticosteroid therapy, radiation therapy, alcoholism, Gaucher's disease, systemic lupus erythematosus, rheumatoid arthritis. Corticosteroid therapy is considered the most frequent risk factor for developing avascular necrosis. In this paper we report a case of a 19-year old female patient who developed avascular necrosis of the right femoral head following treatment of severe aplastic anaemia. Clinical symptoms included groin pain and fever, painful abduction and internal rotation, tenderness over the right hip joint. The plain X-ray was not specific. However magnetic resonance imaging of the hip revealed changes characteristic for avascular necrosis. Conservative treatment was administrated. Two years after the onset of first clinical symptoms the patient is able to walk without pain, although the range of motion of the right hip joint is partially diminished. We evaluated the possible risk factors of AVN, diagnostic methods and prognosis. The onset of avascular necrosis should be considered as one of the relevant complications in patients with severe aplastic anaemia following immunosuppressive treatment.

Loading of Cervical Spine when Head is Rotated

The neck is more susceptible to injury during an insult in the forward direction if the head is not initially facing straight ahead. (A typical example of this is when a vehicle occupant is checking traffic to the right or left at an intersection before proceeding.) However, the ability to characterize this behavior has not progressed much beyond the qualitative because practical constraints limit testing with conventional physical surrogates. This shortfall is tackled in this study by employing a model validated elsewhere to represent a range of real-world events with the power of great specificity for parameters of importance. Of primary concern is the variation in head angle, which can now be investigated across a wide spectrum of values that was not possible with previous approaches. The quantitative results computed here provide an extraordinarily high level of detail and they show how the potential for injury can change from low to significant within a matter of degrees. This explains why a seemingly harmless impact can cause trauma in some cases when none would otherwise be expected.

The aim of this study was to assess the change in trends in the management of traumatic brain injury (TBI) at a level I trauma center and the utilization of resources as a result of this change in management. The management of TBI has been evolving with trends toward management of minimally injured patients with intracranial hemorrhage exclusively by trauma surgeons. A 5-year (2009-2014) prospective database on all patients with TBI (skull fracture/intracranial hemorrhage on head computed tomography) presenting to a level I trauma center was analyzed for patient demographics, injuries, admission physiology, computed tomographic scan results, and hospital outcomes. These records were matched to the institutional registry and hospital financial database. A total of 2184 patients were included with median (interquartile range) Glasgow Coma Scale score of 15 (12-15), and median (interquartile range) head-abbreviated injury scale score of 3 (2-4). The distribution of types and size of intracranial bleeds remained unchanged throughout the study period. The proportion of TBI managed exclusively by trauma surgeons increased significantly over the years from 6.8% to 40.1% (P < 0.001). Proportion of patients who received neurosurgical consultations (P < 0.001) and repeat head computed tomographic scans (P < 0.001), hospital length of stay (P = 0.028), and costs (P < 0.001) decreased significantly over time. The overall mortality rate (18.5%) and rate of intervention (14.1%) remained unchanged. TBI patients can be selectively managed without initially involving neurosurgeons safely in a cost-effective manner, resulting in more effective use of precious resources.

The socioeconomic status has been associated with disparities in the incidence and mortality of traumatic injuries. However, there is a lack of studies on the level of health insurance with regard to various epidemiologic data of traumatic injuries, which this study opted to clarify. All consecutive 6595 patients admitted to a level one trauma center in 2012 and 2013 were included in this retrospective cohort study. Patients were grouped according to their health insurance status (public versus private extended health care insurance) and compared with regard to several epidemiologic variables, that is, the type of injuries, inhospital outcome, and surgical procedures. Public insurance coverage was significantly more common than private insurance (75% versus 25%). Public insurance was associated with younger age, male sex, transfers to another hospital or mental institution, head concussions, head fractures, and increased mortality. Contrarily, patients with private insurance were more often associated with longer hospital stay, discharge to a rehabilitation clinic, fractures of the proximal humerus, and shoulder dislocations. However, there were no significant differences for the remaining majority of studied variables. In a trauma setting, the level of insurance does not seem to play a crucial role in most types of injuries and surgical procedures in a country with a high level of obligatory health care coverage. Nonetheless, it appears that publicly insured patients are more commonly younger, males, transferred to another hospital more often, more prone to head trauma, and subject to increased mortality, whereas privately insured patients show longer hospital stays, increased transfers to rehabilitation clinics, and more fractures of the proximal humerus.

Chiropractic Care for a Patient with Spasmodic Dysphonia Associated with Cervical Spine Trauma

PubMed Central

Waddell, Roger K.

2005-01-01

Abstract Objective To discuss the diagnosis and response to treatment of spasmodic dysphonia in a 25-year-old female vocalist following an auto accident. Clinical Features The voice disorder and neck pain appeared after the traumatic incident. Examination of the cervical spine revealed moderate pain, muscle spasm and restricted joint motion at C-1 and C-5 on the left side. Cervical range of motion was reduced on left rotation. Bilateral manual muscle testing of the trapezius and sternocleidomastoid muscles, which share innervation with the laryngeal muscles by way of the spinal accessory nerve, were weak on the left side. Pre and post accident voice range profiles (phonetograms) that measure singing voice quality were examined. The pre- and post-accident phonetograms revealed significant reduction in voice intensity and fundamental frequency as measured in decibels and hertz. Intervention and Outcome Low-force chiropractic spinal manipulative therapy to C-1 and C-5 was employed. Following a course of care, the patient's singing voice returned to normal, as well as a resolution of her musculo- skeletal complaints. Conclusion It appears that in certain cases, the singing voice can be adversely affected if neck or head trauma is severe enough. This case proposes that trauma with irritation to the cervical spine nerve roots as they communicate with the spinal accessory, and in turn the laryngeal nerves, may be contributory in some functional voice disorders or muscle tension dysphonia.

Trauma remains one of the important causes of severe disability and high mortality. In this study, we looked at the epidemiology of neurotrauma in our region so as to highlight essential factors for trauma prevention program. This is a cross-sectional study of all neurotrauma cases admitted to the neurosurgery service of our hospital over an 18-month period. Information was obtained on patients' demographic data, etiology of injury, duration of injury, site, and cause of accident among others. One hundred forty-three patients were included in the study. The injuries occurred mostly in males and in the third decade. Most of the patients were students and traders. Eighty-one percent of the accidents were due to road traffic crash (RTC), and the most common contributory factors were head-on collision (46.2%) and overtaking (28.6%). Five of six patients who had RTC in the first decade of life were pedestrians. There were more crashes within the cities. None of the patients who had motorcycle accidents used helmet and only four patients used seatbelts at the time of the accident. Transfer to hospital was mostly in vehicles other than ambulance. Neurotrauma in our study was mostly due to RTC and it is most common in young male students. Contributory factors were head on collision and overtaking. Copyright © 2013 Elsevier Inc.

The avascular necrosis of the femoral head is an illness induced by the cutoff of blood flow to the femoral head and it affects mostly young adults between the ages of 30 and 50 years, raising therapeutic and diagnostic issues. Many risk factors are incriminated in the development of avascular necrosis of the femoral head like: trauma, chronic alcohol consumption, smoking, administration of corticosteroid drugs, most of the cases are considered to be idiopathic. The main goal of our paper is to describe the macroscopic and microscopic variations of the bone structure, which occur in patients with avascular necrosis of the femoral head. The biological material needed for our study was obtained following hip arthroplasty surgery in 26 patients between the ages of 29 and 59 years, which previously were diagnosed with avascular necrosis of the femoral head and admitted in the Orthopedics Department of the Emergency County Hospital of Craiova (Romania) between 2010 and 2011. From a macroscopic point of view, we found well defined areas of necrosis, most of which were neatly demarcated of the adjacent viable tissue by hyperemic areas, loss of shape and contour of the femoral head and transformations of the articular cartilage above the area of necrosis. When examined under the microscope, we found vast areas of fibrosis, narrow bone trabeculae, obstructed blood vessels or blood vessels with clots inside, hypertrophic fat cells, bone sequestration but also small cells and pyknotic nuclei. The microscopic and macroscopic findings on the femoral head sections varied with the patients and the stage of the disease.

Femoral head avascular necrosis is caused by disruption of the blood supply of the femoral head, which finally results in hip dysfunction. Non traumatic osteonecrosis may related with corticosteroid use, alcohol abuse, SLE, hemoglobinopathies or exposure to cytotoxic agents. But avascular necrosis of the femoral head (ANFH) due to heroin use is a rare condition. We report a patient with bilateral ANFH due to heroin use treated by simultaneous bilateral hip arthroplasty. 37 year-old male patient presented with bilateral hip pain that had been occurring for four years. The patient had no history of smoking, excessive drinking, using corticosteroid and the other drugs or trauma but used heroin for 10 years. In clinic and radiologic examination indicated advanced degenerative changes on both hip due to femoral head avascular necrosis. The patient was treated with simultaneous bilateral total hip arthroplasty. After 6 months postoperatively the active hip range of motion was painless. Avascular femoral head necrosis caused by the using of heroin is rare. Ultimately, osteonecrosis of the femoral head occurs through one final common pathway, which is decreased blood flow to the femoral head that leads bone ischemia and death. But it is still unknown that heroin's systemic effects. Intravenous drug use more as a serious problem for today. There is a need for comprehensive studies to demonstrate effects of heroin on bone and vascularity metabolism. Heroin use will be important problem for population. That's why is crucial to understand the effect of heroin. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

The purposes of this study were to identify the relative frequency of Monteggia fracture patterns and to investigate the required frequency of open reduction of the proximal radiocapitellar joint. We identified 121 Monteggia fractures at a Level I trauma center from 1996 to 2015 and included 119 in this study. These fractures were identified using a database search for the appropriate International Classification of Diseases, Ninth Revision and Current Procedural Terminology codes as well as individual surgeons' logs. Two fellowship-trained hand surgeons reviewed the identified patients' x-rays and operative notes. Each fracture was classified using Bado's original description, excluding transolecranon and Monteggia variants. Bado I lesion represented 68% (81 of 119) of Monteggia fractures. Annular ligament incarceration preventing radial head reduction occurred in approximately 17% (14 of 81) of this Bado type. Revision fixation of the ulna was not necessary (none of 119 cases) and functional range of motion (average arc, 117°) was recovered in most patients. The reoperation rate of 20% (23 of 119) was related to the severity of the presenting injury and hardware prominence. Most radial head dislocations associated with Monteggia fractures occur anteriorly and will reduce with anatomic plating of the ulna. In cases where the radial head fails to reduce, entrapment of the annular ligament can be expected and open reduction is required. Revision fixation of the ulna to achieve reduction of the radial head is uncommon in our experience. Prognostic IV. Copyright © 2018 American Society for Surgery of the Hand.

To improve the efficiency and appropriateness of computed tomography (CT) use in children with minor head trauma, clinical prediction rules were derived and validated by the Pediatric Emergency Care Applied Research Network (PECARN). The objective of this study was to conduct a cost-effectiveness analysis comparing the PECARN traumatic brain injury prediction rules to usual care for selective CT use. We used decision analytic modeling to project the outcomes, costs, and cost-effectiveness of applying the PECARN rules compared with usual care in a hypothetical cohort of 1,000 children with minor blunt head trauma. Clinical management was directed by level of risk as specified by the presence or absence of variables in the PECARN traumatic brain injury prediction rules. Immediate costs of care (diagnostic testing, treatment [not including clinician time], and hospital stay) were derived on single-center data. Quality-adjusted life-year losses related to the sequelae of clinically important traumatic brain injuries and to radiation-induced cancers, number of CT scans, number of radiation-induced cancers, number of missed clinically important traumatic brain injury, and total costs were evaluated. Compared with the usual care strategy, the PECARN strategy was projected to miss slightly more children with clinically important traumatic brain injuries (0.26 versus 0.02 per 1,000 children) but used fewer cranial CT scans (274 versus 353), resulted in fewer radiation-induced cancers (0.34 versus 0.45), cost less ($904,940 versus $954,420), and had lower net quality-adjusted life-year loss (-4.64 versus -5.79). Because the PECARN strategy was more effective (less quality-adjusted life-year loss) and less costly, it dominated the usual care strategy. Results were robust under sensitivity analyses. Application of the PECARN traumatic brain injury prediction rules for children with minor head trauma would lead to beneficial outcomes and more cost-effective care.

Evaluation of children for cervical spine injuries (CSIs) after blunt trauma is complicated, particularly if the patient is unresponsive because of severe traumatic brain injury. Plain radiography and computed tomography (CT) are commonly used, but CT combined with magnetic resonance imaging (MRI) is still considered the gold standard in CSI detection. However, MRI is expensive and can delay cervical clearance. The purpose of this study is to determine the added benefit of MRI as an adjunct to CT in the clearance of children with severe head trauma. We performed a retrospective chart review of pediatric head trauma patients admitted to the pediatric intensive care unit at St. Louis Children's Hospital from 2002 to 2012. Patients who received both cervical spine CT and MRI and presented with a Glasgow Coma Scale score of 8 or lower were included in the study. Imaging was analyzed by two pediatric trauma subspecialists and classified as demonstrating "no injury," "stable injury," or "unstable injury." Results were compared, and discrepancies between CT and MRI findings were noted. A total of 1,196 head-injured children were admitted to the pediatric intensive care unit between January 2002 and December 2012. Sixty-three children underwent CT and MRI and met Glasgow Coma Scale criteria. Seven children were identified with negative CT and positive MRI findings, but none of these injuries were considered unstable by our criteria. Five children were determined to have unstable injuries, and all were detected on CT. The results of this study suggest that MRI does not detect unstable CSIs in the setting of negative CT imaging. Given the limited patient population for this study, further and more extensive studies investigating the utility of MRI in the head-injured pediatric patient are warranted.

Childhood trauma is emerging as a risk factor for schizophrenia, but its mechanism with respect to etiology is unknown. One possible pathway is through leucocyte telomere length (LTL) shortening, a measure of cellular aging associated with trauma. This study examined early trauma and LTL shortening in schizophrenia and considered sex effects. The early trauma inventory (ETI) was administered to 48 adults with DSM-5 schizophrenia and 18 comparison participants. LTL was measured using qPCR. Cases had significantly more global trauma (F=4.10, p<0.01) and traumatic events (F=11.23, p<0.001), but case and control groups had similar LTL (1.91±0.74 and 1.83±0.62: p=0.68). The association of early trauma and LTL differed by sex in cases and controls (Fisher's R: Z<0.05). Significant negative associations were shown in male cases and, conversely, in female controls. For example, physical punishment was associated LTL shortening in males' cases (r=-0.429, p<01). Only female controls showed significant telomere shortening in association with early trauma. This data confirms the substantial excess of early trauma among schizophrenia cases. There were significant sex-differences in the relationship of the trauma to LTL, with only male cases showing the expected shortening. There were converse sex effects in the control group. Mean LTL was notably similar in cases and controls, despite the trauma-related shortening in male cases, cigarette smoking, older age and chronic illness of the cases. Factors may lengthen LTL in some schizophrenia cases. The converse sex differences in the cases are consistent with findings defective sexual differentiation in schizophrenia, consistent with other findings in the field. Copyright © 2018 Elsevier B.V.

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 noted on CT are uncommon in children younger than 2 years with minor blunt head trauma and guardian reports of the child acting abnormally with no other clinical findings suspicious for TBI. Computed tomographic scans are generally not indicated in these children although observation in the emergency department may be warranted. PMID:26502172

Although accidents during pregnancy are fairly rare, besides endangering the mother, they nearly always mean a vital threat to the fetus: lethality rates are up to 8% for the mother and up to 34% for the fetus. Besides depression of the circulatory system in the mother, coupled with fetal hypoxy, injury to the placenta and uterus is also possible. Moreover, the unborn child may be injured by direct trauma. If the fetus sustains a direct injury, the head of the child is affected in the majority of instances. In addition, the risk of an intrauterine death is very high. If the injured baby survives after a section, permanent damage must be taken into account. Pregnant women who are injured in an accident should quickly be checked by sonography and cardiotocography. If no danger is expected for the child, the usual therapeutic rules that apply for traumatology should be followed. If the mother and child are endangered, a cesarean section must be undertaken along with simultaneous accident-related surgery on the mother. Case reports are presented on three cases in our clinic last year, and the current literature is discussed. All three mothers and newborns survived because of the cooperation between surgeons, gynecologists and pediatricians.

Use of video-assisted intubation devices in the management of patients with trauma.

Patients with trauma may have airways that are difficult to manage. Patients with blunt trauma are at increased risk of unrecognized cervical spine injury, especially patients with head trauma. Manual in-line stabilization reduces cervical motion and should be applied whenever a cervical collar is removed. All airway interventions cause some degree of cervical spine motion. Flexible fiberoptic intubation causes the least cervical motion of all intubation approaches, and rigid video laryngoscopy provides a good laryngeal view and eases intubation difficulty. In emergency medicine departments, video laryngoscopy use is growing and observational data suggest an improved success rate compared with direct laryngoscopy. Copyright © 2013 Elsevier Inc.

Objective Brain atrophy and subdural hygroma were well known factors that enlarge the subdural space, which induced formation of chronic subdural hematoma (CSDH). Thus, we identified the subdural volume that could be used to predict the rate of future CSDH after head trauma using a computed tomography (CT) volumetric analysis. Methods A single institution case-control study was conducted involving 1,186 patients who visited our hospital after head trauma from January 1, 2010 to December 31, 2014. Fifty-one patients with delayed CSDH were identified, and 50 patients with age and sex matched for control. Intracranial volume (ICV), the brain parenchyme, and the subdural space were segmented using CT image-based software. To adjust for variations in head size, volume ratios were assessed as a percentage of ICV [brain volume index (BVI), subdural volume index (SVI)]. The maximum depth of the subdural space on both sides was used to estimate the SVI. Results Before adjusting for cranium size, brain volume tended to be smaller, and subdural space volume was significantly larger in the CSDH group (p=0.138, p=0.021, respectively). The BVI and SVI were significantly different (p=0.003, p=0.001, respectively). SVI [area under the curve (AUC), 77.3%; p=0.008] was a more reliable technique for predicting CSDH than BVI (AUC, 68.1%; p=0.001). Bilateral subdural depth (sum of subdural depth on both sides) increased linearly with SVI (p<0.0001). Conclusion Subdural space volume was significantly larger in CSDH groups. SVI was a more reliable technique for predicting CSDH. Bilateral subdural depth was useful to measure SVI. PMID:27169071

Neuroendocrine abnormalities in patients with traumatic brain injury

This article provides an overview of hypothalamic and pituitary alterations in brain trauma, including the incidence of hypothalamic-pituitary damage, injury mechanisms, features of the hypothalamic-pituitary defects, and major hypothalamic-pituitary disturbances in brain trauma. While hypothalamic-pituitary lesions have been commonly described at postmortem examination, only a limited number of clinical cases of traumatic hypothalamic-pituitary dysfunction have been reported, probably because head injury of sufficient severity to cause hypothalamic and pituitary damage usually leads to early death. With the improvement in rescue measures, an increasing number of severely head-injured patients with hypothalamic-pituitary dysfunction will survive to be seen by clinicians. Patterns of endocrine abnormalities following brain trauma vary depending on whether the injury site is in the hypothalamus, the anterior or posterior pituitary, or the upper or lower portion of the pituitary stalk. Injury predominantly to the hypothalamus can produce dissociated ACTH-cortisol levels with no response to insulin-induced hypoglycemia and a limited or failed metopirone test, hypothyroxinemia with a preserved thyroid-stimulating hormone response to thyrotropin-releasing hormone, low gonadotropin levels with a normal response to gonadotropin-releasing hormone, a variable growth hormone (GH) level with a paradoxical rise in GH after glucose loading, hyperprolactinemia, the syndrome of inappropriate ADH secretion (SIADH), temporary or permanent diabetes insipidus (DI), disturbed glucose metabolism, and loss of body temperature control. Severe damage to the lower pituitary stalk or anterior lobe can cause low basal levels of all anterior pituitary hormones and eliminate responses to their releasing factors. Only a few cases showed typical features of hypothalamic or pituitary dysfunction. Most severe injuries are sufficient to damage both structures and produce a mixed endocrine picture. Increased intracranial pressure, which releases vasopressin by altering normal hypothalamic anatomy, may represent a unique type of stress to neuroendocrine systems and may contribute to adrenal secretion by a mechanism that requires intact brainstem function. Endocrine function should be monitored in brain-injured patients with basilar skull fractures and protracted posttraumatic amnesia, and patients with SIADH or DI should be closely monitored for other endocrine abnormalities.

This is a retrospective study designed to evaluate the pattern and severity of injuries that result from low falls, defined as falls from less than 20 ft, subsequent mortality, and requirements of hospital resources. Our hypothesis is that many of these injuries, even without cardiopulmonary instability, are worthy of trauma center care. The records of all patients entered into the hospital trauma registry at an urban Level I trauma center during the years 1991 through 1997 who suffered low falls and who either died after admission or were hospitalized for at least 3 days were reviewed. Patients suffering isolated hip fractures were excluded. One hundred seventy-six patients constituted the study population. This group accounts for about 2% of all admissions for falls at our institution. Patterns of injury were examined. Age, mechanism of injury, Injury Severity Score (ISS), and cardiopulmonary or neurologic instability on admission were documented. Mortality, length of intensive care unit and hospital stays, as well as billed hospital charges, were reviewed. The majority of patients (62%) were younger than 50 years. Sixty patients had ISS >15 and 116 patients had ISS >9. Sixty patients had multisystem injuries requiring specialty care. Head injuries were found in 81 patients (35%), and vertebral fractures or spinal cord injuries were found in 49 patients (22%), including 9 quadriplegics and 5 paraplegics. There were seven patients with intra-abdominal injuries (five spleen and two bowel injuries). There was one patient with a rupture of the thoracic aorta. Seventeen patients had deteriorating neurologic or pulmonary function on arrival, but the majority (90%) were stable. Of the 159 "stable" patients, 48 suffered head injuries, 7 were quadriplegic, and 3 were paraplegic. All intra-abdominal injuries were in this group. Overall, 14 of 176 patients (8%) died. Seven deaths were in patients older than 60 years, and seven deaths were in younger patients (p = 0.04). The majority of deaths (9 of 14) were from head trauma. Care in the intensive care unit was required in 92 of 176 patients. Nine patients had billed charges exceeding $100,000. Low falls can cause significant injuries, most commonly to the head and spine. Based on mechanism of injury alone, patients injured in low falls might not be taken to trauma centers. We have found, however, that many of these patients sustain serious multisystem injuries, even though they are stable initially. Although these patients represent only a fraction of those who fall, our study would support adjustment of triage guidelines to recommend transport of such patients, particularly elderly patients, to trauma centers.

The objective of the study was to determine if hypothermia in pediatric trauma patients is associated with increased mortality. We reviewed the charts of level 1 trauma patients aged 3 months to 17 years who presented between September 2006 and March 2008. We analyzed data for patients with temperatures recorded within 30 minutes of arrival to the pediatric emergency department. Logistic regression models were used to test for associations of hypothermia with death while adjusting for mode of transport, season of year, and presence of intracranial pathology as documented by an abnormal head computed tomographic scan. Of the 226 level 1 trauma patients presenting during the study period, 190 met inclusion criteria. Twenty-one patients (11%) died. The odds ratio (OR) of a hypothermic patient dying was 9.2 times that of a normothermic patient when adjusting for seasonal variation (95% confidence interval [CI], 3.2-26.2; P < 0.0001). The OR of a hypothermic patient dying was 8.7 times that of a normothermic patient when adjusting for mode of transport (ground vs air) (95% CI, 3.1-24.6; P < 0.0001). Although it did not reach statistical significance, there was a trend toward an association between hypothermia and the presence of traumatic brain injury as evidenced by an abnormal head computed tomographic scan (OR = 2.4; 95% CI, 0.9-6.0; P = .07). Hypothermia is a risk factor for increased mortality in pediatric trauma patients. This pilot study warrants a more detailed, multicenter analysis to assess the impact of hypothermia in the pediatric trauma patient. Copyright © 2011 Elsevier Inc. All rights reserved.

To evaluate the architecture, integration requirements, and execution characteristics of a remote clinical decision support (CDS) service used in a multicenter clinical trial. The trial tested the efficacy of implementing brain injury prediction rules for children with minor blunt head trauma. We integrated the Epic(®) electronic health record (EHR) with the Enterprise Clinical Rules Service (ECRS), a web-based CDS service, at two emergency departments. Patterns of CDS review included either a delayed, near-real-time review, where the physician viewed CDS recommendations generated by the nursing assessment, or a real-time review, where the physician viewed recommendations generated by their own documentation. A backstopping, vendor-based CDS triggered with zero delay when no recommendation was available in the EHR from the web-service. We assessed the execution characteristics of the integrated system and the source of the generated recommendations viewed by physicians. The ECRS mean execution time was 0.74 ±0.72 s. Overall execution time was substantially different at the two sites, with mean total transaction times of 19.67 and 3.99 s. Of 1930 analyzed transactions from the two sites, 60% (310/521) of all physician documentation-initiated recommendations and 99% (1390/1409) of all nurse documentation-initiated recommendations originated from the remote web service. The remote CDS system was the source of recommendations in more than half of the real-time cases and virtually all the near-real-time cases. Comparisons are limited by allowable variation in user workflow and resolution of the EHR clock. With maturation and adoption of standards for CDS services, remote CDS shows promise to decrease time-to-trial for multicenter evaluations of candidate decision support interventions.

to assess predictors of intra-abdominal injuries in blunt trauma patients admitted without abdominal pain or abnormalities on the abdomen physical examination. We conducted a retrospective analysis of trauma registry data, including adult blunt trauma patients admitted from 2008 to 2010 who sustained no abdominal pain or abnormalities on physical examination of the abdomen at admission and were submitted to computed tomography of the abdomen and/or exploratory laparotomy. Patients were assigned into: Group 1 (with intra-abdominal injuries) or Group 2 (without intra-abdominal injuries). Variables were compared between groups to identify those significantly associated with the presence of intra-abdominal injuries, adopting p<0.05 as significant. Subsequently, the variables with p<0.20 on bivariate analysis were selected to create a logistic regression model using the forward stepwise method. A total of 268 cases met the inclusion criteria. Patients in Group I were characterized as having significantly (p<0.05) lower mean AIS score for the head segment (1.0 ± 1.4 vs. 1.8 ± 1.9), as well as higher mean AIS thorax score (1.6 ± 1.7 vs. 0.9 ± 1.5) and ISS (25.7 ± 14.5 vs. 17,1 ± 13,1). The rate of abdominal injuries was significantly higher in run-over pedestrians (37.3%) and in motorcyclists (36.0%) (p<0.001). The resultant logistic regression model provided 73.5% accuracy for identifying abdominal injuries. The variables included were: motorcyclist accident as trauma mechanism (p<0.001 - OR 5.51; 95%CI 2.40-12.64), presence of rib fractures (p<0.003 - OR 3.00; 95%CI 1.47-6.14), run-over pedestrian as trauma mechanism (p=0.008 - OR 2.85; 95%CI 1.13-6.22) and abnormal neurological physical exam at admission (p=0.015 - OR 0.44; 95%CI 0.22-0.85). Intra-abdominal injuries were predominantly associated with trauma mechanism and presence of chest injuries.

Procedures involved in grooming, bathing, and other pet services can often lead animals to death. Of the necropsies of 1391 animals carried out at a private diagnostic laboratory in Sao Paulo, Brazil from 2004 to 2009, 94 were dogs that died during the above-mentioned procedures. Young male dogs and small breeds like Poodle Miniature, Yorkshire Terrier, and Lhasa Apso were most frequently observed. Blunt-force trauma was responsible for the deaths of 31% of the animals, with a higher incidence of trauma to the head, characterized chiefly by fractures and nervous tissue lesions. In the other 69% of cases, the animals showed signs of stress, and died due to pulmonary edema and hemorrhage. As we cannot rule out the intentional character in some situations, this article provides veterinary forensic support for veterinarians and pet owners, especially in lawsuits, helping in finding the cause of animal's death in such pet services. © 2013 American Academy of Forensic Sciences.

The Injury Severity Score (ISS) is widely used as a method for rating severity of injury. The ISS is the sum of the squares of the three worst Abbreviated Injury Scale (AIS) values from three body regions. Patients with penetrating injuries tend to have higher mortality rates for a given ISS than patients with blunt injuries. This is thought to be secondary to the increased prevalence of multiple severe injuries in the same body region in patients with penetrating injuries, which the ISS does not account for. We hypothesized that the mechanism-based difference in mortality could be attributed to certain ISS ranges and specific AIS values by body region. Outcome and injury scoring data were obtained from transfused patients admitted to 23 Level I trauma centers. ISS values were grouped into categories, and a logistic regression model was created. Mortality for each ISS category was determined and compared with the ISS 1 to 15 group. An interaction term was added to evaluate the effect of mechanism. Additional logistic regression models were created to examine each AIS category individually. There were 2,292 patients in the cohort. An overall interaction between ISS and mechanism was observed (p = 0.049). Mortality rates between blunt and penetrating patients with an ISS between 25 and 40 were significantly different (23.6 vs. 36.1%; p = 0.022). Within this range, the magnitude of the difference in mortality was far higher for penetrating patients with head injuries (75% vs. 37% for blunt) than truncal injuries (26% vs. 17% for blunt). Penetrating trauma patients with an AIS head of 4 or 5, AIS abdomen of 3, or AIS extremity of 3 all had adjusted mortality rates higher than blunt trauma patients with those values. Significant differences in mortality between blunt and penetrating trauma patients exist at certain ISS and AIS category values. The mortality difference is greatest for head injured patients.

Scared or scarred: Could 'dissociogenic' lesions predispose to nonepileptic seizures after head trauma?

PubMed

Popkirov, Stoyan; Carson, Alan J; Stone, Jon

2018-04-14

A history of head injury is common in patients with psychogenic nonepileptic seizures (PNES). This association has so far been interpreted as either spurious or psychologically mediated. Biased recall and misattribution could foster illness beliefs about brain damage that promote symptom production. Furthermore, the emotional impact of head injury could induce long-term changes in stress responsivity. Lastly, maladaptive cognitive-behavioural processes involving symptom modelling and aversive conditioning, known to play a role in functional neurological disorders, could contribute to the development of PNES after head trauma. Lesional effects of head injury, on the other hand, remain unexplored in the context of PNES. However, even mild traumatic brain injury without structural MRI abnormalities on routine imaging can lead to disruptions of network connectivity that correlate with short-term cognitive impairments and psychiatric symptoms. Since alterations in global functional connectivity have been demonstrated in PNES patients using imaging and electroencephalography, we hypothesize that, in some patients, TBI and the associated disruption of long-range association fibres could contribute to the individual propensity for dissociative experiences in general and PNES in particular. This possibility is explored in the context of new cognitive-behavioural models of PNES pathogenesis, and the concept of a "dissociogenic" brain lesion is introduced.

Understanding patterns of trauma is important to determining cause and manner of death. A thorough evaluation of taphonomy, trauma, and bone fracture mechanisms is necessary to reconstruct the circumstances of the death. This study examines the skeletal trauma caused by boat propeller strikes in terms of wound characteristics and location based on three cases from Rhode Island. These case studies review the traumatic characteristics caused by propeller injuries and highlight the anatomic regions most likely to sustain skeletal trauma. With this information, investigators may be able to identify propeller trauma even in severely decomposed remains. The discussion of boat propeller trauma also raises issues regarding how forensic anthropologists and forensic pathologists classify trauma (specifically blunt force vs. sharp) and highlights semantic issues arising in trauma classification. The study also discusses why these propeller cases should be classified as blunt trauma rather than sharp or chop/hack trauma. Ultimately, the authors urge consistency and communication between pathologist and forensic anthropologists performing trauma analyses. © 2012 American Academy of Forensic Sciences.

One of the major applications of dual-energy computed tomography (DECT) is automated bone removal (BR). We hypothesized that the visualization of acute intracranial hemorrhage could be improved on BRCT by removing bone as it has the highest density tissue in the head. This preliminary study evaluated the efficacy of a DE BR algorithm for the head CT of trauma patients. Sixteen patients with acute intracranial hemorrhage within 1 day after head trauma were enrolled in this study. All CT examinations were performed on a dual-source dual-energy CT scanner. BRCT images were generated using the Bone Removal Application. Simulated standard CT and BRCT images were visually reviewed in terms of detectability (presence or absence) of acute hemorrhagic lesions. DECT depicted 28 epidural/subdural hemorrhages, 17 contusional hemorrhages, and 7 subarachnoid hemorrhages. In detecting epidural/subdural hemorrhage, BRCT [28/28 (100%)] was significantly superior to simulated standard CT [17/28 (61%)] (p = .001). In detecting contusional hemorrhage, BRCT [17/17 (100%)] was also significantly superior to simulated standard CT [11/17 (65%)] (p = .0092). BRCT was superior to simulated standard CT in detecting acute intracranial hemorrhage. BRCT could improve the detection of small intracranial hemorrhages, particularly those adjacent to bone, by removing bone that can interfere with the visualization of small acute hemorrhage. In an emergency such as head trauma, BRCT can be used as support imaging in combination with simulated standard CT and bone scale CT, although BRCT cannot replace a simulated standard CT.

The Abbreviated Injury Scale (AIS) measures injury severity of a trauma patient with a numeric method for ranking anatomy-based specific injuries. The summation of the squares of the three most severe injuries in the AIS of six predefined body regions comprises the Injury Severity Score (ISS). It assumes that the mortality of a given AIS value is similar across all body regions. However, such an assumption is less explored in the literature. In this study, we aimed to compare the mortality rates of the patients with the same AIS value in different injured body regions in a level I trauma center. Hospitalized adult trauma patients with isolated serious to critical injury (AIS of 3 to 5) between 1 January 2009, and 31 December 2016, from the Trauma Registry System in a level I trauma center were grouped according to the injured body regions (including, the head/neck, thorax, abdomen, or extremities) and were exclusively compared according to their AIS stratum. Categorical data were compared using the two-sided Fisher exact or Pearson chi-square tests. ANOVA with Games-Howell post hoc test was performed to assess the differences in continuous data of the patients with injury in different body regions. The primary outcome of the study was in-hospital mortality. The adjusted odds ratios (AORs) were estimated using a stepwise selection of a multivariable regression model adjusted by controlling the confounding variables such as sex, age, comorbidities, and ISS. Survival curves were estimated with the Kaplan-Meier approach with a corresponding log-rank test. The patients with AIS of 5 for abdomen injury and those with AIS of 3 for extremity injury had a significantly lower odds of adjusted mortality (adjusted odds ratio (AOR) 0.1, 95% confidence interval (CI) 0.01-0.39, p = 0.004 and AOR 0.3, 95% CI 0.15-0.51, p < 0.001, respectively) than that of the patients with head/neck injury. However, the patients with AIS of 4 for extremity injury demonstrated significantly higher odds of adjusted mortality (AOR 8.4, 95% CI 2.84-25.07, p < 0.001) than the patients with head/neck injury. This study found that the risks to mortality in the patients with a given AIS value of serious to critical injury in different injured body regions were not the same, even after controlling for confounding variables such as sex, age, comorbidities, and ISS.

The Abbreviated Injury Scale (AIS) measures injury severity of a trauma patient with a numeric method for ranking anatomy-based specific injuries. The summation of the squares of the three most severe injuries in the AIS of six predefined body regions comprises the Injury Severity Score (ISS). It assumes that the mortality of a given AIS value is similar across all body regions. However, such an assumption is less explored in the literature. In this study, we aimed to compare the mortality rates of the patients with the same AIS value in different injured body regions in a level I trauma center. Hospitalized adult trauma patients with isolated serious to critical injury (AIS of 3 to 5) between 1 January 2009, and 31 December 2016, from the Trauma Registry System in a level I trauma center were grouped according to the injured body regions (including, the head/neck, thorax, abdomen, or extremities) and were exclusively compared according to their AIS stratum. Categorical data were compared using the two-sided Fisher exact or Pearson chi-square tests. ANOVA with Games-Howell post hoc test was performed to assess the differences in continuous data of the patients with injury in different body regions. The primary outcome of the study was in-hospital mortality. The adjusted odds ratios (AORs) were estimated using a stepwise selection of a multivariable regression model adjusted by controlling the confounding variables such as sex, age, comorbidities, and ISS. Survival curves were estimated with the Kaplan–Meier approach with a corresponding log-rank test. The patients with AIS of 5 for abdomen injury and those with AIS of 3 for extremity injury had a significantly lower odds of adjusted mortality (adjusted odds ratio (AOR) 0.1, 95% confidence interval (CI) 0.01–0.39, p = 0.004 and AOR 0.3, 95% CI 0.15–0.51, p < 0.001, respectively) than that of the patients with head/neck injury. However, the patients with AIS of 4 for extremity injury demonstrated significantly higher odds of adjusted mortality (AOR 8.4, 95% CI 2.84–25.07, p < 0.001) than the patients with head/neck injury. This study found that the risks to mortality in the patients with a given AIS value of serious to critical injury in different injured body regions were not the same, even after controlling for confounding variables such as sex, age, comorbidities, and ISS.

Experience with several, previously unreported, intentional face-first immersion burns led us to evaluate the distribution of inflicted and unintentional immersion scald burns in a hospital series. (1) Authors' clinical and legal practices; (2) Burn center at regional Level 1 trauma hospital. : (1) Case series of face-first, inflicted immersion burn victims; (2) Consecutive hospitalized scald burn victims younger than 5 years old, 1/3/1996 to 3/25/2000. (1) Individual case reports; (2) Retrospective records review. Simple descriptive statistics, Fisher Exact test and t test. (1) Six cases of inflicted head and neck immersion injury are described. Four were tap water and 2 food/drink scalds. (2) 22/195 hospitalized victims had sustained immersion burns, 13 from tap water and 9 from other fluids. Six (46%) tap water immersions and no (0%) other immersions had inflicted injuries (P = 0.05). Two of the tap water immersions and one other source immersion included burning of the head and neck. Of these, one tap water immersion, but no other immersion, was inflicted. In no patients were head and neck injuries the sole or predominant site of scalding. In all, 9 children sustained inflicted scalds. Bilateral lower extremity tap water immersion scalds occurred in 100% (6/6) of abusive and 29% (2/7) of unintentional injuries (P = 0.02). Buttock and perineal injuries occurred in 67% (4/6) inflicted versus 29% (2/7) unintentional tap water immersion scalds (P = 0.28). Other fluids caused bilateral lower extremity immersion burns in 3/9 (33 %) unintentionally injured patients, but no abused children (NS). Craniofacial immersion injury, although seen by the authors in legal cases, is infrequent. It was present incidentally in one inflicted tap water burn in the consecutive hospital series. This series affirms the predominance of bilateral lower extremity burns in inflicted tap water immersions. Buttock/perineal immersions were more common with abuse than with unintentional injury.

Noninvasive Intracranial Volume and Pressure Measurements Using Ultrasound (Head and Spinal)

Prevention of secondary brain injuries following head trauma can be accomplished most easily when intracranial pressure (ICP) is monitored. However, current measurement techniques are invasive and thus not practical in the combat environment. The Pulsed Phase Lock Loop device, which was developed and patented by consultants Drs. Yost and Cantrell, uses a unique, noninvasive ultrasonic phase comparison method to measure slight changes in cranial volume which occur with changes in ICP. Year two studies included whole body head-up and head-down tilting effects on intracranial compliance and pressure in six healthy volunteers.

Morbidity following Mexico City's 1985 earthquakes: clinical and epidemiologic findings from hospitals and emergency units.

PubMed

Sánchez-Carrillo, C I

1989-01-01

Medical records of 822 inpatients and outpatients cared for by the Department of the Federal District medical services during the 1985 Mexico City earthquakes were reviewed. Record incompleteness varied between 92.8 percent and 14.0 percent for the various study variables. No gender differences were detected among the groups; more than 70.0 percent of the patients were ages 15 to 64 years. Multiple traumatic injuries were frequent for inpatients across age groups, while simple contusions were more frequent among outpatients. Multiple head traumas, thorax-abdomen multiple traumas, and simple fractures of an arm or leg were more frequently recorded for inpatients than for outpatients. Head wounds with contusions; simple contusion of the thorax-abdomen, arms, and legs; and psychological trauma were more frequently recorded for outpatients. Although a great many records were incomplete, the data may reflect what actually happened to these patients, given the similarity of the findings with other reports of disasters. Improved record keeping during emergencies is needed to standardize the quantity and the reliability of the data so that statistical and medical care requirements are soundly based. The use of standard questionnaires for data collection is stressed to facilitate the management of clinical and epidemiologic activities. Longitudinal studies are needed to determine patterns of physical injuries, psychological trauma, and survival.

Blunt gastric injuries.

Gastric rupture after blunt abdominal trauma is a rare injury with few reports in the literature. The purpose of this study was to review our experience with blunt gastric injuries and compare outcomes with small bowel or colon injuries. All patients with hollow viscus perforations after blunt abdominal trauma from 1992 to 2005 at our level I trauma center were reviewed. Of 35,033 blunt trauma admissions, there were 268 (0.7%) patients with a total of 319 perforating hollow viscus injuries, 25 (0.07%) of which were blunt gastric injuries. When compared with the small bowel or colon injuries, the blunt gastric injury group had a higher Injury Severity Score (22 versus 17, P = 0.04), more patients with a chest Abbreviated Injury Score greater than 2 (36% versus 12%, P < 0.01), and a shorter interval from injury to laparotomy (221 versus 366 minutes, P = 0.017). Multivariate analysis identified five independent risk factors for mortality: age older than 55 years, head Abbreviated Injury Score greater than 2, chest Abbreviated Injury Score greater than 2, the presence of hypotension on admission, and Glasgow Coma Scale 8 or less. The results of this study suggest that mortality in patients with blunt hollow viscus injuries can be attributed to concurrent head and chest injuries, but not the specific hollow viscus organ that is injured.

Trauma is a major cause of paediatric mortality in sub-Saharan Africa. In absence of pre-hospital care, the injury mechanism and cause of death is difficult to characterise. Injury characteristics of pre-hospital deaths (PHD) versus in-hospital deaths (IHD) were compared. Using our trauma surveillance database, a retrospective, descriptive analysis of children (<18 years) presenting to Kamuzu Central Hospital in Lilongwe, Malawi from 2008 to 2013 was performed. Patient and injury characteristics of pre-hospital and in-hospital deaths were compared with univariate and bivariate analysis. Of 30,462 paediatric trauma patients presenting between 2008 and 2013, 170 and 173 were PHD and IHD, respectively. In PHD and IHD patients mean age was 7.3±4.9 v 5.2±4.3 (p<0.001), respectively. IHD patients were more likely transported via ambulance than those PHD, 51.2% v 8.3% (p<0.001). The primary mechanisms of injury for PHD were road traffic injuries (RTI) (45.8%) and drowning (22.0%), with head injury (46.7%) being the predominant cause of death. Burns were the leading mechanism of injury (61.8%) and cause of death (61.9%) in IHD, with a mean total body surface area involvement of 24.7±16.0%. RTI remains Malawi's major driver of paediatric mortality. A majority of these deaths attributed to head injury occur prior to hospitalisation; therefore the mortality burden is underestimated if accounting for IHD alone. Death in burn patients is likely due to under-resuscitation or sepsis. Improving pre-hospital care and head injury and burn management can improve injury related paediatric mortality.

Severe hepatic trauma: nonoperative management, definitive repair, or damage control surgery?

Management of severe liver injuries has evolved to include the options for nonoperative management and damage control surgery. The present study analyzes the criteria for choosing between nonoperative management and early surgery, and definitive repair versus damage control strategy during early surgery. In a retrospective analysis of 144 patients with severe (AAST grade III-V) liver injuries (94% blunt trauma), early laparotomy was performed in 50 patients. Initial management was nonoperative in 94 blunt trauma patients with 8 failures. Uni- and multivariate analyses were used to calculate predictor odds ratios (OR) with 95% confidence intervals (CI). Factors associated with early laparotomy in blunt trauma included shock on admission, associated grade IV-V splenic injury, grade IV-V head injury, and grade V liver injury. Only shock was an independent predictor (OR, 26.1; 95% CI, 8.9-77.1; P < 0.001). The presence of a grade IV-V splenic injury predicted damage control strategy (OR infinite; P = 0.021). Failed nonoperative management was associated with grade IV-V splenic injury (OR, 14.00; 95% CI, 1.67-117.55), and shock (OR, 6.82; 95% CI, 1.49-31.29). The hospital mortality rate was 15%; 8 of 21 deaths were liver-related. Shock (OR, 9.3; 95% CI, 2.4-35.8; P = 0.001) and severe head injury (OR, 9.25; 95% CI, 3.0-28.9; P = 0.000) were independent predictors for mortality. In patients with severe liver injury, associated severe splenic injury favors early laparotomy and damage control strategy. Patients who arrive in shock or have an associated severe splenic injury should not be managed nonoperatively. In addition to severe head injury, uncontrollable bleeding from the liver injury is still a major cause of early death.

The inflammatory response is an important part of the pathophysiology of severe injury and, in particular, of severe traumatic brain injury (TBI). This study evaluates the inflammatory course following major trauma and focuses on the effect of severe TBI on inflammatory markers. This was a retrospective analysis of prospectively collected data in 123 severely injured (ISS ≥16) trauma patients. The study cohort was divided into patients with isolated TBI (Head AIS ≥3, all other AIS <3), polytraumatized patients with severe TBI (Head AIS ≥3; AIS of other body area ≥3; Polytrauma+TBI) and polytraumatized patients without TBI (Head AIS <3; Polytrauma). Levels of inflammatory markers (Interleukin-6 [IL-6], C-reactive Protein [CRP], leukocytes) measured upon arrival and through hospital days 1-3 were compared between the groups. On admission and through hospital day 3, IL-6 levels were significantly different between the 3 groups (admission: isolated TBI vs. Polytrauma+TBI vs. Polytrauma; 94±16 vs. 149±20 vs. 245±50pg/mL; p<0.05). Interleukin-6 levels peaked on hospital day 1 and declined thereafter. C-reactive protein and leukocyte counts were not significantly different between the cohorts on arrival and peaked on hospital day 2 and 1, respectively. In patients with severe TBI, admission IL-6 levels significantly predicted the development of septic complications (ROC analysis, AUC: 0.88, p=0.001, 95% CI: 0.79-0.97) and multiple organ dysfunction (ROC analysis, AUC: 0.83, p=0.001, 95% CI: 0.69-0.96). Severe TBI reduced the inflammatory response following trauma. Significant correlations between admission IL-6 values and the development of MOF, sepsis and the neurological outcome were found in patients with TBI. Copyright © 2015 Elsevier GmbH.

2013-01-01

With technological improvements in body armour and increasing use of improvised explosive devices, it is the injuries to head, face and neck are the cause for maximum fatalities as military personnel are surviving wounds that would have otherwise been fatal. The priorities of battlefield surgical treatment are to save life, eyesight and limbs and then to give the best functional and aesthetic outcome for other wounds. Modern day battlefields pose unique demands on the deployed surgical teams and management of head and neck wounds demands multispecialty approach. Optimal result will depend on teamwork of head and neck trauma management team, which should also include otolaryngologist. Data collected by various deployed HFN surgical teams is studied and quoted in the article to give factual figures. Otorhinolaryngology becomes a crucial sub-speciality in the care of the injured and military otorhinolaryngologists need to be trained and deployed accordingly. The otolaryngologist's clinical knowledge base and surgical domain allows the ENT surgeon to uniquely contribute in response to mass casualty incident. Military planners need to recognize the felt need and respond by deploying teams of specialist head and neck surgeons which should also include otorhinolaryngologists.

To evaluate massive transfusion protocol practices by trauma type at a level I trauma center. A retrospective analysis was performed on a sample of 76 trauma patients with MTP activation between March 2010 and January 2015 at a regional trauma center. Patient demographics, transfusion practices, and clinical outcomes were compared by type of trauma sustained. Penetrating trauma patients who required MTP activation were significantly younger, had lower injury severity score (ISS), higher probability of survival (POS), decreased mortality, and higher Glasgow Coma scale (GCS) compared to blunt trauma patients. Overall, the mortality rate was 38.16%. The most common injury sustained among blunt trauma patients was head injury (36.21%), whereas the majority of the penetrating trauma patients sustained abdominal injuries (55.56%). Although the admission coagulation parameters and timing of coagulopathy were not significantly different between the two groups of patients, a significantly higher proportion of penetrating trauma patients received high plasma content therapy relative to blunt trauma patients (p < 0.01). Despite the use of the same MTP for all injured patients requiring massive transfusion, significant differences existed between blunt trauma patients and penetrating trauma patients. These differences in transfusion characteristics and outcomes following MTP activation underscore the complexity of implementing MTPs and warrant vigilant transfusion practices to improve outcomes in trauma patients.

In trauma populations, improvements in outcome are documented in institutions with higher case volumes. However, it is not known whether improved outcomes are attributable to the case volume within specific higher-risk groups, such as the elderly, or to the case volume among all trauma patients treated by an institution. To test the hypothesis that outcomes of trauma care for geriatric patients are affected differently by the volume of geriatric cases and nongeriatric cases of an institution. This retrospective cohort study using a statewide trauma registry was set in state-designated levels 1 and 2 trauma centers in Pennsylvania. It included 39 431 eligible geriatric trauma patients (aged >65 years) in the Pennsylvania Trauma Outcomes Study. In-hospital mortality, major complications, and mortality after major complications (failure to rescue). Between 2001 and 2010, 39 431 geriatric trauma patients and 105 046 nongeriatric patients were captured in a review of outcomes in 20 state-designated levels 1 and 2 trauma centers. Larger volumes of geriatric trauma patients were significantly associated with lower odds of in-hospital mortality, major complications, and failure to rescue. In contrast, larger nongeriatric trauma volumes were significantly associated with higher odds of major complications in geriatric patients. Higher rates of in-hospital mortality, major complications, and failure to rescue were associated with lower volumes of geriatric trauma care and paradoxically with higher volumes of trauma care for younger patients. These findings offer the possibility that outcomes might be improved with differentiated pathways of care for geriatric trauma patients.

Summary Surgery on the head and neck region may be complicated by vascular trauma, caused by direct injury on the vascular wall. Lesions of the arteries are more dangerous than the venous one. The traumatic lesion may cause laceration of the artery wall, spasm, dissection, arteriovenous fistula, occlusion or pseudoaneurysm. We present a case of a child with a giant ICA pseudoaneurysm after tonsillectomy, manifested by pulsing mass and respiratory distress, which was treated by endovascular approach, occluding the lesion and the proximal artery with Histoacryl. We reinforce that the endovascular approach is the better way to treat most of the traumatic vascular lesions. PMID:20594516

Aggressive fibromatosis is an uncommon, benign tumor of fibroblastic origin with high potential for local invasion. Less than a quarter of these lesions are located in the head and neck, and although extremely rare, associations have been demonstrated with physical trauma. We describe a unique case of oropharyngeal fibromatosis with traumaticetiology, managed successfully with surgical excision of the lesion with negative surgical margins. A 5-year old patient was found to have an aggressive fibromatosis causing oropharyngeal stenosis following tonsillectomy. We demonstrate that surgical resection with a clear margin allowed for alleviation of stenosis without recurrences reported since the procedure. Copyright © 2018 Elsevier B.V. All rights reserved.

Laparoscopic repair of traumatic perforation of the urinary bladder.

2001-12-01

Laparoscopy as a diagnostic modality in trauma has been reported. However, therapeutic laparoscopy for trauma remains a controversial subject. We present a case of laparoscopic repair of a traumatic bladder rupture. A 25-year-old man was brought to the emergency room after a head-on collision. Physical examination was unremarkable with the exception of gross hematuria upon insertion of a urinary catheter. Computed tomography scan of the abdomen demonstrated a small amount of free intraperitoneal fluid. An anteroposterior cystogram was obtained which showed no intraperitoneal or extraperitoneal leak. Repeat examinations of the abdomen revealed a mild tenderness in the lower abdomen. Because of the presence of unexplained free intraperitoneal fluid and equivocal signs of peritoneal irritation, exploratory laparoscopy was performed. Three 5-mm ports and a 5-mm laparoscope were used. Laparoscopic examination of the abdomen revealed a 4-cm rupture at the dome of the bladder. The laceration was sutured in two layers using an intracorporeal technique. The patient was discharged on the second postoperative day with indwelling urinary catheter. Eight days after the operation, a repeated cystogram revealed no evidence of leak. We believe that laparoscopic exploration for trauma in hemodynamically stable patients is feasible. The repair of simple intraabdominal injuries such as bladder rupture can be safely performed.

Emergency pancreatico-duodenectomy(EPD) is a very rare procedure and few reports are present in medical literature. It is an uncommon approach, usually used for emergency surgical treatment of abdominal trauma that involves the head of the pancreas or the duodenum, but it is also a surgical tool for the treatment of ruptured aneurysms, bleeding pseudocysts, duodenal perforations, uncontrollable hemorrhage from ulcers and tumors, severe infectious complications of acute pancreatitis or endoscopic retrograde cholangiopancreatography related complications (1,2). It is rarely used as the first line of treatment in case of acute bleeding from arterial pseudoaneurysm of the cephalad region of the pancreas. We present the case of a bleeding pseudoaneurysm of the cefalic region of the pancreas in a young patient with previously undiagnosed chronic pancreatitis and with suspicion of a malignant process located in the head of the pancreas. We performed a pancreatico-duodenectomy with resection of superior mesenteric and portal vein with reconstruction using Gore-Tex vascular graft due to probable venous abutment. Postoperative course was without any major complications, only minor grad-I pancreatic fistula was present. We determine that EPD is a useful tool in the treatment of such cases. It can be used as a first line of treatment or secondary to endovascular stenting or embolization. Celsius.

Penetrating BB shot head wound in an asymptomatic 9-year-old girl: the ultimate teaching moment.

1997-01-01

Air rifle BB injuries represent a common type of childhood accident. The purpose of this case report is to encourage all providers of pediatric care to include nonpowder firearm safety education with standard well-child anticipatory guidance. A case report is described and experience with similar injuries is discussed from cases found in a literature review using the key words "air rifle," "patient education," "pediatric," "ballistics," and "trauma." A 9-year-old girl came to the emergency department after having been accidentally shot in the head by her 7-year-old brother with a toy air rifle. The BB shot entered through the left cheek and traversed up into the soft tissue above the mandible, just medial to the internal carotid artery, and posterior to the facial nerve. Other than local pain, she was entirely asymptomatic. The cheek was repaired without complication. Conservative therapy was recommended. She and her family were given anticipatory guidance, and her course thereafter was uneventful. Firearm education is not a standard part of every well-child encounter. Injuries by all types of firearms are increasing at epidemic rates. Questioning about the accessibility of both powder- and non-powder-based weapons (ie, air rifle) and providing routine safety education should become the standard of care at all well-child encounters.

Traumatic macular hole is a disease whose pathogenesis is not fully understood and the best treatment guideline is controversial. We report 2 cases of traumatic macular hole with different treatment approaches. In the first case, a 9-year-old boy presented with a traumatic macular hole secondary to blunt ocular trauma with a stone, and initial vision of 20/300. He underwent surgical repair and his final vision was 20/70 with hole closure after a 1 year follow-up. In the second case, a 20-year-old woman suffered a penetrating bullet wound on the left side of her forehead. The injury caused optic nerve head avulsion in the left eye with loss of light perception. The right eye had a traumatic macular hole and signs suggestive of sclopetaria chorioretinitis, with 20/60 vision. This case was initially observed and vision improved to 20/30 with reduction of the hole diameter. Vision and hole diameter remained stable after 8 months.

Conversion disorder refers to functional bodily impairments that can be precipitated by high stress situations including trauma and surgery. Symptoms of conversion disorder may mimic or complicate otolaryngology diseases in the pediatric population. In this report, the authors describe 3 cases of conversion disorder that presented to a pediatric otolaryngology-head and neck surgery practice. This report highlights a unique population of patients who have not previously been investigated. The clinical presentation and management of these cases are discussed in detail. Non-organic otolaryngology symptoms of conversion disorder in the pediatric population are reviewed. In addition, we discuss the challenges faced by clinicians in appropriately identifying and treating these patients and present an approach to management of their care. In this report, the authors highlight the importance of considering psychogenic illnesses in patients with atypical clinical presentations of otolaryngology disorders.

Cystic neoplasms of the pancreas are diagnosed frequently due to early use of abdominal imaging techniques. Intraductal papillary mucinous neoplasm, mucinous cystic neoplasm, and serous pseudopapillary neoplasia are considered pre-cancerous lesions because of frequent transformation to cancer. Complete surgical resection of the benign lesion is a pancreatic cancer preventive treatment. The application for a limited surgical resection for the benign lesions is increasingly used to reduce the surgical trauma with a short- and long-term benefit compared to major surgical procedures. Duodenum-preserving total pancreatic head resection introduced for inflammatory tumors in the pancreatic head transfers to the patient with a benign cystic lesion located in the pancreatic head, the advantages of a minimalized surgical treatment. Based on the experience of 17 patients treated for cystic neoplastic lesions with duodenum-preserving total pancreatic head resection, the surgical technique of total pancreatic head resection for adenoma, borderline tumors, and carcinoma in situ of cystic neoplasm is presented. A segmental resection of the peripapillary duodenum is recommended in case of suspected tissue ischemia of the peripapillary duodenum. In 305 patients, collected from the literature by PubMed search, in about 40% of the patients a segmental resection of the duodenum and 60% a duodenum and common bile duct-preserving total pancreatic head resection has been performed. Hospital mortality of the 17 patients was 0%. In 305 patients collected, the hospital mortality was 0.65%, 13.2% experienced a delay of gastric emptying and a pancreatic fistula in 18.2%. Recurrence of the disease was 1.5%. Thirty-two of 175 patients had carcinoma in situ. Duodenum-preserving total pancreatic head resection for benign cystic neoplastic lesions is a safe surgical procedure with low post-operative morbidity and mortality.

Outcome following trauma and health care access are important components of health care planning. Resources are limited and quality information is required. We set the objective of comparing the outcomes for patients suffering significant trauma in urban and rural environments in Scotland. The study was designed as a 2 year prospective observational study set in the west of Scotland, which has a population of 2.58 million persons. Primary outcome measures were defined as the total number of inpatient days, total number of intensive care unit days, and mortality. The participants were patients suffering moderate (ISS 9-15) and major (ISS>15) trauma within the region. The statistical analysis consisted of chi square test for categorical data and Mann Whitney U test for comparison of medians. There were 3,962 urban (85%) and 674 rural patients (15%). Urban patients were older (50 versus 46 years, p = 0.02), were largely male (62% versus 57%, p = 0.02), and suffered more penetrating traumas (9.9% versus 1.9%, p < 0.001). All prehospital times are significantly longer for rural patients (p < 0.001), include more air ambulance transfers (p < 0.001), and are characterized by greater paramedic presence (p < 0.001). Excluding neurosurgical and spinal injuries transfers, there was a higher proportion of transfers in the rural major trauma group (p = 0.002). There were more serious head injuries in the urban group (p = 0.04), and also a higher proportion of urban patients with head injuries transferred to the regional neurosurgical unit (p = 0.037). There were no differences in length of total inpatient stay (median 8 days, p = 0.7), total length of stay in the intensive care unit (median two days, p = 0.4), or mortality (324 deaths, moderate trauma, p = 0.13; major trauma, p = 0.8). Long prehospital times in the rural environment were not associated with differences in mortality or length of stay in moderately and severely injured patients in the west of Scotland. This may lend support to a policy of rationalization of trauma services in Scotland.

The purpose of this study was to investigate etiological, clinical, and pathological characteristics of traumatic injuries of the middle ear ossicular chain and to evaluate hearing outcome after surgery. Thirty consecutive patients (31 ears) with traumatic ossicular injuries operated on between 2004 and 2015 in two tertiary referral otologic centers were retrospectively analyzed. Traumatic events, clinical features, ossicular lesions, treatment procedures, and audiometric results were evaluated. Air conduction (AC), bone conduction (BC), and air-bone gap (ABG) were analyzed preoperatively and postoperatively. Amsterdam Hearing Evaluation Plots (AHEPs) were used to visualize the individual hearing results. The mean age at the moment of trauma was 27.9±17.1 years (range, 2-75 years) and the mean age at surgery was 33.2±16.3 years (range, 5-75 years). In 10 cases (32.3%), the injury occurred by a fall on the head and in 9 (29.0%) by a traffic accident. Isolated luxation of the incus was observed in 8 cases (25.8%). Dislocation of the stapes footplate was seen in 4 cases (12.9%). The postoperative ABG closure to within 10 and 20 dB was 30% and 76.7%, respectively. Ossicular chain injury by direct or indirect trauma can provoke hearing loss, tinnitus, and vertigo. As injuries are heterogeneous, they require a tailored surgical approach. In this study, the overall hearing outcome after surgical repair was favorable.

Are patient specific meshes required for EIT head imaging?

Jehl, Markus; Aristovich, Kirill; Faulkner, Mayo; Holder, David

Head imaging with electrical impedance tomography (EIT) is usually done with time-differential measurements, to reduce time-invariant modelling errors. Previous research suggested that more accurate head models improved image quality, but no thorough analysis has been done on the required accuracy. We propose a novel pipeline for creation of precise head meshes from magnetic resonance imaging and computed tomography scans, which was applied to four different heads. Voltages were simulated on all four heads for perturbations of different magnitude, haemorrhage and ischaemia, in five different positions and for three levels of instrumentation noise. Statistical analysis showed that reconstructions on the correct mesh were on average 25% better than on the other meshes. However, the stroke detection rates were not improved. We conclude that a generic head mesh is sufficient for monitoring patients for secondary strokes following head trauma.

Background: Abdominal injuries contribute significantly to battlefield trauma morbidity and mortality. This study sought to determine the incidence, demographics, clinical features, spectrum, severity, management, and outcome of abdominal trauma during a civilian conflict. Materials and Methods: A prospective analysis of patients treated for abdominal trauma during the Jos civil crises between December 2010 and May 2012 at the Jos University Teaching Hospital. Results: A total of 109 victims of communal conflicts with abdominal injuries were managed during the study period with 89 (81.7%) males and 20 (18.3%) females representing about 12.2% of the total 897 combat related injuries. The peak age incidence was between 21 and 40 years (range: 3–71 years). The most frequently injured intra-abdominal organs were the small intestine 69 (63.3%), colon 48 (44%), and liver 41 (37.6%). Forty-four (40.4%) patients had extra-abdominal injuries involving the chest in 17 (15.6%), musculoskeletal 12 (11%), and the head in 9 (8.3%). The most prevalent weapon injuries were gunshot 76 (69.7%), explosives 12 (11%), stab injuries 11 (10.1%), and blunt abdominal trauma 10 (9.2%). The injury severity score varied from 8 to 52 (mean: 20.8) with a fatality rate of 11 (10.1%) and morbidity rate of 29 (26.6%). Presence of irreversible shock, 3 or more injured intra-abdominal organs, severe head injuries, and delayed presentation were the main factors associated with mortality. Conclusion: Abdominal trauma is major life-threatening injuries during conflicts. Substantial mortality occurred with loss of nearly one in every 10 hospitalized victims despite aggressive emergency room resuscitation. The resources expenditure, propensity for death and expediency of timing reinforce the need for early access to the wounded in a concerted trauma care systems. PMID:26957819

Introduction The National Emergency X-radiography Utilization Study (NEXUS) criteria are used extensively in emergency departments to rule out C-spine injuries (CSI) in the general population. Although the NEXUS validation set included 2,943 elderly patients, multiple case reports and the Canadian C-Spine Rules question the validity of applying NEXUS to geriatric populations. The objective of this study was to validate a modified NEXUS criteria in a low-risk elderly fall population with two changes: a modified definition for distracting injury and the definition of normal mentation. Methods This is a prospective, observational cohort study of geriatric fall patients who presented to a Level I trauma center and were not triaged to the trauma bay. Providers enrolled non-intoxicated patients at baseline mental status with no lateralizing neurologic deficits. They recorded midline neck tenderness, signs of trauma, and presence of other distracting injury. Results We enrolled 800 patients. One patient fall event was excluded due to duplicate enrollment, and four were lost to follow up, leaving 795 for analysis. Average age was 83.6 (range 65–101). The numbers in parenthesis after the negative predictive value represent confidence interval. There were 11 (1.4%) cervical spine injuries. One hundred seventeen patients had midline tenderness and seven of these had CSI; 366 patients had signs of trauma to the face/neck, and 10 of these patients had CSI. Using signs of trauma to the head/neck as the only distracting injury and baseline mental status as normal alertness, the modified NEXUS criteria was 100% sensitive (CI [67.9–100]) with a negative predictive value of 100 (98.7–100). Conclusion Our study suggests that a modified NEXUS criteria can be safely applied to low-risk elderly falls. PMID:27330655

Introduction Paediatric trauma is a significant burden to healthcare worldwide and accounts for a large proportion of deaths in the UK. Methods This retrospective study examined the epidemiological data from a major trauma centre in the UK between January 2012 and December 2014, reviewing all cases of moderate to severe trauma in children. Patients were included if aged ≤16 years and if they had an abbreviated injury scale score of ≥2 in one or more body region. Results A total of 213 patients were included in the study, with a mean age of 7.8 years (standard deviation [SD]: 5.2 years). The most common cause of injury was vehicle related incidents (46%). The median length of hospital stay was 5 days (interquartile range [IQR]: 4-10 days). Approximately half (52%) of the patients had to stay in the intensive care unit, for a median of 1 day (IQR: 0-2 days). The mortality rate was 6.6%. The mean injury severity score was 19 (SD: 10). Pearson's correlation coefficient showed a positive correlation for injury severity score with length of stay in hospital (p<0.001). Conclusions There is significant variation in mechanism of injury, severity and pattern of paediatric trauma across age groups. A multidisciplinary team approach is imperative, and patients should be managed in specialist centres to optimise their care and eventual functional recovery. Head injury remained the most common, with significant mortality in all age groups. Rib fractures and pelvic fractures should be considered a marker for the severity of injury, and should alert doctors to look for other associated injuries.

The optimal timing for emergency surgical interventions and implementation of protocols for trauma surgery is insufficient in the literature. The Groote Schuur emergency surgery triage (GSEST) system, based on Cape Triaging Score (CTS), is followed at Groote Schuur Hospital (GSH) for triaging emergency surgical cases including trauma cases. The study aimed to look at the effect of delay in surgery after scheduling based on the GSEST system has an impact on outcome in terms of postoperative complications and death. Prospective audit of patients presenting to GSH trauma center following penetrating or blunt chest, abdominal, neck and peripheral vascular trauma who underwent surgery over a 4-month period was performed. Post-operative complications were graded according to Clavien-Dindo classification of surgical complications. One-hundred six patients underwent surgery during the study period. One-hundred two (96.2%) cases were related to penetrating trauma. Stab wounds comprised 71 (67%) and gunshot wounds (GSW) 31 (29.2%) cases. Of the 106 cases, 6, 47, 40, and 13 patients were booked as red, orange, yellow, and green, respectively. The median delay for green, yellow, and orange cases was within the expected time. The red patients took unexpectedly longer (median delay 48 min, IQR 35-60 min). Thirty-one (29.3%) patients developed postoperative complications. Among the booked red, orange, yellow, and green cases, postoperative complications developed in 3, 18, 9, and 1 cases, respectively. Only two (1.9%) postoperative deaths were documented during the study period. There was no statistically significant association between operative triage and post-operative complications ( p  = 0.074). Surgical case categorization has been shown to be useful in prioritizing emergency trauma surgical cases in a resource constraint high-volume trauma center.

SUMMARY Severe pediatric head injury has negative consequences for children of all ages. Even mild and moderate head injury results in residual impairment for school-age children and adolescents. Data are needed on the effects of these less severe insults, especially for preschoolers. Although research on the impact of the child’s head injury on the parent–child relationship and family functioning is limited, the experience is likely to be very stressful for the parent and the family. Indeed, family integrity may be at risk. Research is needed that examines the effects of a child’s head injury for the parent and the family over time and identifies factors related to these outcomes. PMID:11249368

Crisis resource management skills are integral to leading the resuscitation of a critically ill patient. Despite their importance, crisis resource management skills (and their associated cognitive processes) have traditionally been difficult to study in the real world. The objective of this study was to derive key cognitive processes underpinning expert performance in resuscitation medicine, using a new eye-tracking-based video capture method during clinical cases. During an 18-month period, a sample of 10 trauma resuscitations led by 4 expert trauma team leaders was analyzed. The physician team leaders were outfitted with mobile eye-tracking glasses for each case. After each resuscitation, participants were debriefed with a modified cognitive task analysis, based on a cued-recall protocol, augmented by viewing their own first-person perspective eye-tracking video from the clinical encounter. Eye-tracking technology was successfully applied as a tool to aid in the qualitative analysis of expert performance in a clinical setting. All participants stated that using these methods helped uncover previously unconscious aspects of their cognition. Overall, 5 major themes were derived from the interviews: logistic awareness, managing uncertainty, visual fixation behaviors, selective attendance to information, and anticipatory behaviors. The novel approach of cognitive task analysis augmented by eye tracking allowed the derivation of 5 unique cognitive processes underpinning expert performance in leading a resuscitation. An understanding of these cognitive processes has the potential to enhance educational methods and to create new assessment modalities of these previously tacit aspects of expertise in this field.

Devastating fourth-degree electrical injuries to the face and head pose significant reconstructive challenges. To date, there have been few peer-reviewed articles in the literature that describe those reconstructive challenges. The authors present the largest case series to date that describes the management of these injuries, including the incorporation of face transplantation. A retrospective case series was conducted of patients with devastating electrical injuries to the face who were managed at two level-1 trauma centers between 2007 and 2011. Data describing patient injuries, initial management, and reconstructive procedures were collected. Five patients with devastating electrical injuries to the face were reviewed. After initial stabilization and treatment of life-threatening injuries, all five underwent burn excision and microsurgical reconstruction using distant flaps. Two of the patients eventually underwent face transplantation. The authors describe differences in management between the two trauma centers, one of which had the availability for composite tissue allotransplantation; the other did not. Also described is how initial attempts at traditional reconstruction affected the eventual face transplantation. The care of patients with complex electrical burns must be conducted in a multidisciplinary fashion. As with all other trauma, the initial priority should be management of the airway, breathing, and circulation. Additional considerations include cardiac arrhythmias and renal impairment attributable to myoglobinuria. Before embarking on aggressive reconstruction attempts, it is advisable to determine early whether the patient is a candidate for face transplantation in order to avoid antigen sensitization, loss of a reconstructive "lifeboat," surgical plane disruption, and sacrifice of potential recipient vessels.

Combined pancreatic-duodenal injuries in blunt abdominal trauma are rare. These injuries are associated with high morbidity and mortality, and their emergent management is a challenge. We report a case of combined complete pancreatic (through the neck) and duodenal (first part) transections in a 24-year-old male secondary to blunt abdominal trauma following a motor vehicle crash. The duodenal stumps were closed separately and a gastrojejunostomy performed for intestinal continuity. The transacted head of pancreas main duct was suture ligated and parenchyma was over sewn and buttressed with omentum. The edge of the body and tail pancreatic segment was freshened and an end to side pancreatico-jejunostomy was fashioned. A drain was left in situ. Post operatively the patient developed a pancreatic fistula which resolved with conservative management. After ten months of follow up the patient was well and showed no signs and symptoms of pancreatic insufficiency. Lengthy, complex procedures in pancreatic injuries have been associated with poor outcomes. Distal pancreatectomy or Whipple's procedure for trauma are viable options for complete pancreatic transections. But when there is concern that the residual proximal pancreatic tissue is inadequate to provide endocrine or exocrine function, preservation of the pancreatic tissue distal to the injury becomes an option. Combined pancreatic and duodenal injuries are rare and often fatal. Early identification, resuscitation and surgical intervention is warranted. Because of the large number of possible combinations of injuries to the pancreas and duodenum, no one form of therapy is appropriate for all patients. Copyright © 2017 The Authors.

Femoral head and neck fractures in children are uncommon, accounting for fewer than 1% of all pediatric fractures and fewer than 8% of all hip fractures. Furthermore, traumatic transphyseal hip fracture is rare to present in daily practice especially when associated with an acetabular fracture. A twelve years old boy, not known to have any chronic illnesses, presented to the emergency department as a case of polytrauma after a road traffic accident. Signs of left hip dislocation were discovered upon physical examination. X-rays and CT scans, revealed a complete transphyseal posterior dislocation and a left anterior column fracture of the acetabulum with a minimal displacement. Within five hours, the patient underwent open reduction and internal fixation by two cannulated screws. The acetabular fracture was managed conservatively. After six months, there were clear signs of osteonecrosis of the femoral head. A high-energy trauma in children and adolescents can lead to simultaneous epiphyseal and acetabular fractures which are associated with a poor prognosis. The age seems to play a role as patients older than ten years have a higher risk of developing AVN after sustaining a hip dislocation regardless of the time of intervention. Epiphyseal fracture with dislocation of the femoral head is rare among children and adolescents, especially when associated with an acetabular fracture. AVN in such cases can develop, and it represents a challenge to orthopedic surgeons due to the poor prognosis and the future functional limitations of the joint. Copyright © 2016 The Author(s).

Subdural effusions are uncommon but known complications of arachnoid cysts of the middle cranial fossa. They mainly occur after minor head traumas in young patients. Here, we report eight cases of arachnoid cyst of the middle cranial fossa associated with subdural hematoma in five cases and hygroma in three cases. Major symptoms are signs of raised intracranial pressure. CT scan and MRI showed the cyst and the subdural effusion. An excellent therapeutic result was achieved with evacuation of the subdural fluid via burr holes in the five cases of subdural hematoma while in the two cases of hygroma a subduro-peritoneal shunt was necessary. In the last case, a temporal craniotomy was performed with evacuation of the hygroma and fenestration of the cyst. We suggest treating only the complicating event in the case of a subdural hematoma via burr holes evacuation. Whereas, in the case of hygroma we think that craniotomy with fenestration of the cyst or the use of a subdural shunt are more often needed. Copyright © 2012 Elsevier Masson SAS.

BACKGROUND Repeated head trauma has been associated with risk of neurodegenerative diseases. Few studies have evaluated the long-term risk of neurodegenerative diseases in collision sports like football. OBJECTIVE To assess whether athletes who played American varsity high-school football between 1956 and 1970 have an increased risk of neurodegenerative diseases later in life. PATIENTS AND METHODS We identified all male varsity football players between 1956 and 1970 in the public high schools of Rochester, Minnesota, compared to non-football-playing male varsity swimmers, wrestlers or basketball players. Using the records-linkage system of the Rochester Epidemiology Project, we ascertained the incidence of late-life neurodegenerative diseases: dementia, parkinsonism, or amyotrophic lateral sclerosis. We also recorded medical record-documented head trauma during high school years. RESULTS We identified 296 varsity football players and 190 athletes engaging in other sports. Football players had an increased risk of medically documented head trauma, especially if they played football for more than one year. Compared to non-football athletes, football players did not have an increased risk of neurodegenerative disease overall, nor the individual conditions of dementia, parkinsonism, or amyotrophic lateral sclerosis. CONCLUSION In this community based study, varsity high school football players from 1956 to 1970 did not have an increased risk of developing neurodegenerative diseases compared with athletes engaged in other varsity sports. This was from an era where there was a generally nihilistic view of concussion dangers, less protective equipment and without prohibition of spearing (head-first tackling). However, size and strength of players from prior eras may not be comparable to current high-school athletes. PMID:27979411

Examining the relationship between head trauma and neurodegenerative disease: A review of epidemiology, pathology and neuroimaging techniques

Traumatic brain injuries (TBI) are induced by sudden acceleration-deceleration and/or rotational forces acting on the brain. Diffuse axonal injury (DAI) has been identified as one of the chief underlying causes of morbidity and mortality in head trauma incidents. DAIs refer to microscopic white matter (WM) injuries as a result of shearing forces that induce pathological and anatomical changes within the brain, which potentially contribute to significant impairments later in life. These microscopic injuries are often unidentifiable by the conventional computed tomography (CT) and magnetic resonance (MR) scans employed by emergency departments to initially assess head trauma patients and, as a result, TBIs are incredibly difficult to diagnose. The impairments associated with TBI may be caused by secondary mechanisms that are initiated at the moment of injury, but often have delayed clinical presentations that are difficult to assess due to the initial misdiagnosis. As a result, the true consequences of these head injuries may go unnoticed at the time of injury and for many years thereafter. The purpose of this review is to investigate these consequences of TBI and their potential link to neurodegenerative disease (ND). This review will summarize the current epidemiological findings, the pathological similarities, and new neuroimaging techniques that may help delineate the relationship between TBI and ND. Lastly, this review will discuss future directions and propose new methods to overcome the limitations that are currently impeding research progress. It is imperative that improved techniques are developed to adequately and retrospectively assess TBI history in patients that may have been previously undiagnosed in order to increase the validity and reliability across future epidemiological studies. The authors introduce a new surveillance tool (Retrospective Screening of Traumatic Brain Injury Questionnaire, RESTBI) to address this concern. PMID:25324979

The validated Predicting Abusive Head Trauma (PredAHT) tool estimates the probability of abusive head trauma (AHT) based on combinations of six clinical features: head/neck bruising; apnea; seizures; rib/long-bone fractures; retinal hemorrhages. We aimed to determine the acceptability of PredAHT to child protection professionals. We conducted qualitative semi-structured interviews with 56 participants: clinicians (25), child protection social workers (10), legal practitioners (9, including 4 judges), police officers (8), and pathologists (4), purposively sampled across southwest United Kingdom. Interviews were recorded, transcribed and imported into NVivo for thematic analysis (38% double-coded). We explored participants' evaluations of PredAHT, their opinions about the optimal way to present the calculated probabilities, and their interpretation of probabilities in the context of suspected AHT. Clinicians, child protection social workers and police thought PredAHT would be beneficial as an objective adjunct to their professional judgment, to give them greater confidence in their decisions. Lawyers and pathologists appreciated its value for prompting multidisciplinary investigations, but were uncertain of its usefulness in court. Perceived disadvantages included: possible over-reliance and false reassurance from a low score. Interpretations regarding which percentages equate to 'low', 'medium' or 'high' likelihood of AHT varied; participants preferred a precise % probability over these general terms. Participants would use PredAHT with provisos: if they received multi-agency training to define accepted risk thresholds for consistent interpretation; with knowledge of its development; if it was accepted by colleagues. PredAHT may therefore increase professionals' confidence in their decision-making when investigating suspected AHT, but may be of less value in court. Copyright © 2018 Elsevier Ltd.

To assess whether pediatric trauma patients initially evaluated at referring institutions met Massachusetts statewide trauma field triage criteria for stabilization and immediate transfer to a Pediatric Trauma Center (PTC) without pre-transfer CT imaging. A 3-year retrospective cohort study was completed at our level 1 PTC. Patients with CT imaging at referring institutions were classified according to a triage scheme based on Massachusetts statewide trauma field triage criteria. Demographic data and injury profile characteristics were abstracted from patient medical records and our pediatric trauma registry. A total of 262 patients with 413 CT scans were reviewed from 2008 to 2011. 172 patients scanned (66%, 95% CI: 60%, 71%) met criteria for immediate transfer to a pediatric trauma center. Notably, 110 scans (27% of the total performed at referring institutions) were duplicated within four hours upon arrival to our PTC. GCS score <14 (45%) was the most common requirement for transfer, and CT scan of the head was the most frequent scan obtained (53%). The majority of pediatric trauma patients were subjected to CT scans at referring institutions despite meeting Massachusetts trauma triage guidelines that call for stabilization and immediate transfer to a pediatric trauma center without any CT imaging. © 2014.

Hypopituitarism is a recognized complication of Traumatic Brain Injury (TBI). Resolution of established anterior pituitary hormones deficiency is rare. A woman was initially presented at the age of 22 years with amenorrhoea. Two years earlier she had been involved in a car accident with consequent TBI. At our evaluation, serum oestradiol (E2) was low (3 pmol/l), Luteinizing Hormone (LH) and Follicle Stimulating Hormone (FSH) were borderline low [1.7 and 2.5 mIU/l, normal range (NR) for 20-35 yr old women being 1.4-13 and 2.5-13, respectively] with poor response to Gonadotropin Releasing Hormone (GnRH) (ΔLH = 2.4 and, ΔFSH = 4.0 mIU/l), while serum Prolactin (PRL) was elevated (951 mIU/l; NR: 102-496). No other pituitary hormone deficiencies were observed. Magnetic resonance imaging (MRI) showed a partially empty sella and very thin stalk. Ten years later a new endocrine evaluation was performed. On day 4 of her menstrual cycle, serum values of PRL (196 mIU/l), FSH (4.7 mIU/l), LH (4.8 mIU/l) and E2 (103 pmol/l) were within normal limits for women aged 20-35. Six months after this evaluation (that is, 12 years after trauma), the patient became pregnant and delivered a healthy baby. Our case shows that spontaneous resolution of post-head trauma anterior hypopituitarism occur even many years after head injury. Medicolegal implications are self-evident.

Prehospital Endotracheal Intubation in Warm Climates: Caution is Required.

PubMed

Daniel, Yann; Habas, Sébastien; Cruc, Maximilien

2016-09-01

Out-of-hospital endotracheal intubation is a frequent procedure for trauma care. Nevertheless, in warm climates, sunlight and heat can interfere with the flow of the usual procedure. They can affect the equipment and hinder the operator. There are few data on this issue. The presentation of this case highlights three common complications that may occur when intubating under a hot and bright sun. A 23-year-old man had a car accident in Djibouti, at 11:00 a.m., in broad sunlight. The heat was scorching. Due to a severe head trauma, with a Glasgow Coma Scale score of 8, it was decided to perform an endotracheal intubation. The operator faced three problems: the difficulty of seeing inside the mouth in the bright sunlight, the softening of the tube under the influence of the heat, and the inefficiency of colorimetric CO2 detectors in the warm atmosphere in confirming the proper endotracheal tube placement. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Solutions are simple, but must be known and planned ahead, prior to beginning the procedure: Putting a jacket over his head while doing the laryngoscopy would solve the problem of dazzle; adjuncts like a stylet or gum elastic bougie have to be used at the outset to fix the softening problem; alternative methods to exhaled CO2 detection, such as the syringe aspiration technique, to confirm the proper tube placement, should be available.

Zarb, Francis; McEntee, Mark F; Rainford, Louise

2015-06-01

To evaluate visual grading characteristics (VGC) and ordinal regression analysis during head CT optimisation as a potential alternative to visual grading assessment (VGA), traditionally employed to score anatomical visualisation. Patient images (n = 66) were obtained using current and optimised imaging protocols from two CT suites: a 16-slice scanner at the national Maltese centre for trauma and a 64-slice scanner in a private centre. Local resident radiologists (n = 6) performed VGA followed by VGC and ordinal regression analysis. VGC alone indicated that optimised protocols had similar image quality as current protocols. Ordinal logistic regression analysis provided an in-depth evaluation, criterion by criterion allowing the selective implementation of the protocols. The local radiology review panel supported the implementation of optimised protocols for brain CT examinations (including trauma) in one centre, achieving radiation dose reductions ranging from 24 % to 36 %. In the second centre a 29 % reduction in radiation dose was achieved for follow-up cases. The combined use of VGC and ordinal logistic regression analysis led to clinical decisions being taken on the implementation of the optimised protocols. This improved method of image quality analysis provided the evidence to support imaging protocol optimisation, resulting in significant radiation dose savings. • There is need for scientifically based image quality evaluation during CT optimisation. • VGC and ordinal regression analysis in combination led to better informed clinical decisions. • VGC and ordinal regression analysis led to dose reductions without compromising diagnostic efficacy.

The role of 3DCT for the evaluation of chop injuries in clinical forensic medicine.

2016-09-01

As hatchet blows to the human head frequently cause fatal injuries, the forensic examination of survivors with cranial chop injuries is a rare phenomenon in forensic casework. Besides evaluation of clinical records, photographs, and medico-legal physical examination, the analysis and 3-dimensional reconstruction of pre-treatment computed tomography data (3DCT) must be considered an important and indispensable tool for the assessment of those cases because the characteristics of chopping trauma often appear masked or changed by clinical treatment. In the present article, the role of 3DCT for the evaluation of chop wounds in clinical forensic medicine is demonstrated by an illustrative case report of a young man who was attacked with a hatchet. 3DCT provides additional possibilities for supplementing missing information, such as number and direction of blows as well as weapon identification. Furthermore, 3DCT facilitates demonstration in court and understanding of medical lay people. We conclude that 3DCT is of particular value for the evaluation of survivors of life-threatening head and face injury. An increasing significance of this technique may be expected.

The need for pediatric-specific triage criteria: results from the Florida Trauma Triage Study.

PubMed

Phillips, S; Rond, P C; Kelly, S M; Swartz, P D

1996-12-01

The objective of the Florida Trauma Triage Study was to assess the performance of state-adopted field triage criteria. The study addressed three specific age groups: pediatric (age < 15 years), adult (age 15-54 years), and geriatric (age 55+ years). Since 1990, Florida has used a uniform set of eight triage criteria, known as the trauma scorecard, for triaging adult trauma patients to state-approved trauma centers. However, only five of the criteria are recommended for use with pediatric patients. This article presents the findings regarding the performance of the scorecard when applied to a pediatric population. We used state trauma registry data linked to state hospital discharge data in a retrospective analysis of trauma patients transported by prehospital providers to any acute care hospital within nine selected Florida counties between July 1, 1991, and December 31, 1991. We used cross-table and logistic regression analysis to determine the ability of triage criteria to correctly identify patients who were retrospectively defined as major trauma. We applied the field criteria to physiologic and anatomy/mechanism of injury data contained in the trauma registry to "score" the patient as major or minor trauma. To make our retrospective determination of major or minor trauma we used the protocols developed by an expert medical panel as described by E. J. MacKenzie et al. (1990). We calculated sensitivity, specificity, and the corresponding over- and undertriage rates by comparing patient classifications (major or minor trauma) produced by the triage criteria and the retrospective algorithm. We used logistic regression to identify which triage criteria were statistically significant in predicting major trauma. Pediatric cases accounted for 9.2% of the total study population, 6.0% of all hospitalized cases, and 6.8% of all trauma deaths. Of the 1505 pediatric cases available for analysis, the triage criteria classified 269 cases as expected major trauma and 1236 cases as expected minor trauma. The retrospective algorithm classified 78 cases as expected major trauma and 1427 cases as expected minor trauma. The resulting specificity is 84.8% (15.2% overtriage), and the sensitivity is 66.7% (33.3% undertriage). Logistic regression indicated that, of the eight state-adopted field triage criteria, only the Glasgow coma score, ejection from vehicle, and penetrating injuries have a statistically significant impact on predicting major trauma in pediatric patients. Although the state-adopted trauma scorecard, applied to a pediatric population, produced acceptable overtriage, it did not produce acceptable undertriage. However, our undertriage rate is comparable to the results of other published studies on pediatric trauma. As a result of the Florida Trauma Triage Study, a new pediatric triage instrument was developed. It is currently being field-tested.

Study objective Approximately 1 in 3 computed tomography (CT) scans performed for head injury may be avoidable. We evaluate the association of implementation of the Canadian CT Head Rule on head CT imaging in community emergency departments (EDs). Methods We conducted an interrupted time-series analysis of encounters from January 2014 to December 2015 in 13 Southern California EDs. Adult health plan members with a trauma diagnosis and Glasgow Coma Scale score at ED triage were included. A multicomponent intervention included clinical leadership endorsement, physician education, and integrated clinical decision support. The primary outcome was the proportion of patients receiving a head CT. The unit of analysis was ED encounter, and we compared CT use pre- and postintervention with generalized estimating equations segmented logistic regression, with physician as a clustering variable. Secondary analysis described the yield of identified head injuries pre- and postintervention. Results Included were 44,947 encounters (28,751 preintervention and 16,196 postintervention), resulting in 14,633 (32.6%) head CTs (9,758 preintervention and 4,875 postintervention), with an absolute 5.3% (95% confidence interval [CI] 2.5% to 8.1%) reduction in CT use postintervention. Adjusted pre-post comparison showed a trend in decreasing odds of imaging (odds ratio 0.98; 95% CI 0.96 to 0.99). All but one ED reduced CTs postintervention (0.3% to 8.7%, one ED 0.3% increase), but no interaction between the intervention and study site over time existed (P=.34). After the intervention, diagnostic yield of CT-identified intracranial injuries increased by 2.3% (95% CI 1.5% to 3.1%). Conclusion A multicomponent implementation of the Canadian CT Head Rule was associated with a modest reduction in CT use and an increased diagnostic yield of head CTs for adult trauma encounters in community EDs.

The effect of prehospital helicopter emergency medical services (HEMS) on mortality has been analyzed previously in polytrauma patients with discordant results. Our aim was to compare outcomes in patients with isolated severe blunt traumatic brain injuries (TBIs) transported by HEMS or ground emergency medical services (GEMS). We conducted a National Trauma Data Bank study (2007-2014). All adult patients (≥16 years old) who sustained an isolated severe blunt TBI and were transported by HEMS or GEMS were included in the study. There were 145,559 patients who met the inclusion criteria. Overall, 116,391 (80%) patients were transported via GEMS and 29,168 (20%) via HEMS. Median transportation time was longer for HEMS patients (41 vs. 25 min; p < 0.001). HEMS patients were more likely to have hypotension (2.7% vs. 1.5%; p < 0.001), Glasgow Coma Scale (GCS) score < 9 (38.2% vs. 10.9%; p < 0.001), and head Abbreviation Injury Scale (AIS) score of 5 (20.1% vs. 9.7%; p < 0.001). Stepwise logistic regression analysis identified age ≥ 65 years old, male sex, hypotension, GCS score < 9, prehospital intubation, and head AIS scores 4 and 5 as independent predictors of mortality. Helicopter transportation was independently associated with improved survival (odds ratio [OR] 0.55; 95% confidence interval [CI] 0.47-0.67; p < 0.001). Admission to a Level I trauma center was an independent predictor of survival (OR 0.64; 95% CI 0.53-0.82; p = 0.001). Regardless of head AIS, helicopter transport was an independent predictor of survival (AIS 3: OR 0.35; p < 0.001; AIS 4: OR 0.44; p < 0.001; AIS 5: OR 0.76; p < 0.001). A prolonged transport time was not an independent predictor of mortality. Helicopter transport, in adult patients with isolated severe TBI, is associated with improved survival.

Johannesen, John; Rasbury, Jack

2003-01-01

The NASA critical path road map identifies "trauma and acute medical problems" as a clinical capability risk category (http://criticalDath.isc.nasa.gov). Specific risks include major trauma, organ laceration or contusion, hemoperitoneum, pulmonary failure, pneumo- and hemothorax, burn, open bone fracture, blunt head trauma, and penetrating injury. Mitigation of these risks includes the capability for critical care monitoring. Currently, the International Space Station (ISS) Crew Health Care System (CHeCS) does not provide such a capability. The Clinical Space Medicine Strategic Planning Forum (4/8/97), sponsored by NASA Medical Operations, identified the development of trauma care capabilities as one of the top priorities for space medicine. The Clinical Care Capability Development Project (CCCDP) subsequently undertook the task to address this need.

Introduction While geriatric trauma patients have begun to receive increased attention, little research has investigated assault-related injuries among older adults. Our goal was to describe characteristics, treatment, and outcomes of geriatric assault victims and compare them to geriatric victims of and younger accidental injury assault victims. Patients and Methods We conducted a retrospective analysis of the 2008–2012 National Trauma Data Bank. We identified cases of assault-related injury admitted to trauma centers in patients aged ≥60 using the variable “intent of injury.” Results 3,564 victims of assault-related injury in patients aged ≥60 were identified and compared to 200,194 geriatric accident victims and 94,511 assault victims aged 18–59. Geriatric assault victims were more likely than geriatric accidental injury victims to be male (81% vs. 47%) and were younger than accidental injury victims (67±7 vs. 74±9 years). More geriatric assault victims tested positive for alcohol or drugs than geriatric accident victims (30% vs. 9%). Injuries for geriatric assault victims were more commonly on the face (30%) and head (27%) than for either comparison group. Traumatic brain injury (34%) and penetrating injury (32%) occurred commonly. The median injury severity score (ISS) for geriatric assault victims was 9, with 34% having severe trauma (ISS≥16). Median length of stay was 3 days, 39% required ICU care, and in-hospital mortality was 8%. Injury severity was greater in geriatric than younger adult assault victims, and, even when controlling for injury severity, in-hospital mortality, length of hospitalization, and need for ICU-level care were significantly higher in older adults. Conclusions Geriatric assault victims have characteristics and injury patterns that differ significantly from geriatric accidental injury victims. These victims also have more severe injuries, higher mortality, and poorer outcomes than younger victims. Additional research is necessary to improve identification of these victims and inform treatment strategies for this unique population. PMID:27720184

To investigate the inter-rater reliability and validity of the Neurobehavioural Rating Scale at various stages of recovery after hospitalisation for closed head injury, we studied 101 head trauma patients who had no antecedent neuropsychiatric disorder. The results demonstrated satisfactory inter-rater reliability and showed that the Neurobehavioural Rating Scale reflects both the severity and chronicity of closed head injury. A principal components analysis revealed four factors which were differentially related to severity of head injury and the presence of a frontal lobe mass lesion. Although our findings provide support for utilising clinical ratings of behaviour to investigate sequelae of head injury, extension of this technique to other settings is necessary to evaluate the distinctiveness of the neurobehavioural profile of closed head injury as compared with other aetiologies of brain damage.

The approach to penetrating trauma of the head and neck has undergone significant evolution and offers unique challenges during wartime. Military munitions produce complex injury patterns that challenge conventional diagnosis and management. Mass casualties may not allow for routine exploration of all stable cervical blast injuries. The objective of this study was to review the delayed evaluation of combat-related penetrating neck trauma in patients after evacuation to the United States. From February 2003 through April 2005, a series of patients with military-associated penetrating cervical trauma were evacuated to a single institution, prospectively entered into a database, and retrospectively reviewed. Suspected vascular injury from penetrating neck trauma occurred in 63 patients. Injuries were to zone II in 33%, zone III in 33%, and zone I in 11%. The remaining injuries involved multiple zones, including the lower face or posterior neck. Explosive devices wounded 50 patients (79%), 13 (21%) had high-velocity gunshot wounds, and 19 (30%) had associated intracranial or cervical spine injury. Of the 39 patients (62%) who underwent emergent neck exploration in Iraq or Afghanistan, 21 had 24 injuries requiring ligation (18), vein interposition or primary repair (4), polytetrafluoroethylene (PTFE) graft interposition (1), or patch angioplasty (1). Injuries occurred to the carotid, vertebral, or innominate arteries, or the jugular vein. After evacuation to the United States, all patients underwent radiologic evaluation of the head and neck vasculature. Computed tomography angiography was performed in 45 patients (71%), including six zone II injuries without prior exploration. Forty (63%) underwent diagnostic arteriography that detected pseudoaneurysms (5) or occlusions (8) of the carotid and vertebral arteries. No occult venous injuries were noted. Delayed evaluation resulted in the detection of 12 additional occult injuries and one graft thrombosis in 11 patients. Management included observation (5), vein or PTFE graft repair (3), coil embolization (2), or ligation (1). Penetrating multiple fragment injury to the head and neck is common during wartime. Computed tomography angiography is useful in the delayed evaluation of stable patients, but retained fragments produce suboptimal imaging in the zone of injury. Arteriography remains the imaging study of choice to evaluate for cervical vascular trauma, and its use should be liberalized for combat injuries. Stable injuries may not require immediate neck exploration; however, the high prevalence of occult injuries discovered in this review underscores the need for a complete re-evaluation upon return to the United States.

Assessment of head injury of children due to golf ball impact.

Head trauma injury due to impact by a flying golf ball is one of the most severe possible injury accidents on the golf course. Numerical simulations based on the finite element method are presented to investigate head injury in children due to impact by a flying golf ball. The stress and energy flow patterns in a head model during the golf ball impact are computed for various combinations of striking speed, falling angle of the golf ball before impact, and impact location. It is found that a child is more prone to head injury due to golf ball impact on the frontal and side/temporal areas. The simulated results are found to conform to the clinical reports on children's head injuries from flying golf balls.

The exact alterations of the immune system after polytrauma leading to sepsis and multiple-organ failure are poorly understood. Thus, the early local and systemic inflammatory and apoptotic response was characterized in a new polytrauma model and compared with the alterations seen after single or combined injuries. Anesthetized C57BL/6 mice were subjected to either blunt bilateral chest trauma (Tx), closed head injury, right femur fracture including contralateral soft tissue injury, or a combination of injuries (PTx). After 2 hours or 6 hours, animals were sacrificed, and the systemic as well as the local pulmonary immune response (bronchoalveolar lavage [BAL]/plasma cytokines, lung myeloperoxidase [MPO] activity, and alveolocapillary barrier dysfunction) were evaluated along with lung/brain apoptosis (lung caspase 3 Western blotting, immunohistochemistry, and polymorphonuclear leukocytes [PMN] Annexin V). Hemoglobin, PO2 saturation, and pH did not differ between the experimental groups. Local BAL cytokines/chemokines were significantly increased in almost all groups, which included Tx. There was no further enhancement of this local inflammatory response in the lungs in case of PTx. At 2 hours, all groups except sham and closed head injury alone revealed an increased activity of lung MPO. However, 6 hours after injury, lung MPO remained increased only in the PTx group. Increased BAL protein levels were found, reflecting enhanced lung leakage in all groups with Tx 6 hours after trauma. Only after PTx was neutrophil apoptosis significantly decreased, whereas lung caspase 3 and plasma interleukin 6/keratinocyte chemoattractant (KC) were substantially increased. The combination of different injuries leads to an earlier systemic inflammatory response when compared with the single insults. Interestingly, only after PTx but not after single or double hits was lung apoptosis increased, and PMN apoptosis was decreased along with a prolonged presence of neutrophils in the lungs, which may therefore represent a possible pathomechanism for lung injury after polytrauma.

Unusual death of a transvestite: identification of crime weapon and survival time*.

Cornetta, Sandra; Addante, Annalisa; Zotti, Fiorenza; Dell'Erba, Alessandro

2009-09-01

The authors report a case of a transvestite found murdered near his automobile with several lacerated contused wounds to the face and cranial fractures. Autopsy revealed that the cause of death was a serious head trauma with subdural and subarachnoidal hemorrhages. In order to identify the crime weapon, a scanning electron microscopy (SEM) was used which revealed metallic residue on the skin fragments with the same molecular composition of the car paint. As for survival time, antibody anti-beta-amyloid precursor protein (APP) was applied to brain fragments and brainstem tissue, allowing for axonal varicosities (which form 2 to 3 h following death) to be observed under the optic microscope. So, by using SEM we understood that the fatal cranial-encephalic lesions were the result of the victim's head being repeatedly struck against the car door while anti-betaAPP led to the understanding that the time elapsed between injury and death was less than 2 to 3 h.

Detection of avascular necrosis in adults by single photon emission computed tomography

Collier, B.D.; Johnston, R.P.; Carrera, G.

1984-01-01

Twenty-one adult patients with the clinical diagnosis of avascular necrosis (AVN) of the femoral head were examined with planar bone scintigraphy (high resolution collimator) and single photon emission computed tomography (SPECT). The duration of hip pain ranged from 1 day to 18 months. Risk factors (including steroids, renal transplantation, alcoholism, and trauma) were present in 17 cases. A final diagnosis of AVN (20 hips), osteochondral facture, or stress fracture, was established for 17 patients. The 4 remaining patients, who were radiographically normal and did not complain of pain 3 months later, were thought to have no significant bone pathology. SPECTmore » and planar bone scintigraphy were reported as positive for AVN only if a photopenic bony defect could be identified. In particular, uniformly increased activity throughout the femoral head was not considered to be diagnostic of AVN. The authors conclude that by identifying a photopenic defect which is not evident on planar bone scintigraphy, SPECT can contribute to accurate diagnosis of AVN.« less

We sought to evaluate the risk factors for developing ventilator-associated pneumonia (VAP) and whether the location of intubation posed a risk in trauma patients. Data were retrospectively reviewed for adult trauma patients requiring intubation for > 48 hours, admitted between 2010 and 2013. Patients' demographics, clinical presentations and outcomes were compared according to intubation location (prehospital intubation [PHI] vs. trauma room [TRI]) and presence vs. absence of VAP. Multivariate regression analysis was performed to identify predictors of VAP. Of 471 intubated patients, 332 patients met the inclusion criteria (124 had PHI and 208 had TRI) with a mean age of 30.7±14.8 years. PHI group had lower GCS ( P =0.001), respiratory rate ( P =0.001), and higher frequency of head ( P =0.02) and chest injuries ( P =0.04). The rate of VAP in PHI group was comparable to the TRI group ( P =0.60). Patients who developed VAP were 6 years older, had significantly lower GCS and higher ISS, head AIS, and higher rates of polytrauma. The overall mortality was 7.5%, and was not associated with intubation location or pneumonia rates. In the early-VAP group, gram-positive pathogens were more common, while gram-negative microorganisms were more frequently encountered in the late VAP group. Logistic regression analysis and modeling showed that the impact of the location of intubation in predicting the risk of VAP appeared only when chest injury was included in the models. In trauma, the risk of developing VAP is multifactorial. However, the location of intubation and presence of chest injury could play an important role.

A perilymphatic fistula (PLF) is an abnormal communication between the inner ear and the middle ear that leaks perilymph. PLF is considered rare, but is known to occur during childbirth, straining, weightlifting, head trauma, and diving with middle ear equalizing problems. It has also, anecdotally, been described in connection with flying. The symptoms are uncharacteristic vertigo and, in some cases, hearing impairment and tinnitus. This study describes four cases of PLF during a period of 6 mo in a major Scandinavian airline company employing approximately 3000 cabin attendants (CAs). None of the cases were diagnosed at the primary health care level. All were referred to the Aviation Medical Center for investigation. The PLF diagnosis was based on the case history, Platform Pressure Test (a fistula test), and other vestibular tests. Only one CA has been able to return to flying duties. The article emphasizes the risk of flying with poor middle ear equalization and the necessity of reminding crews and airline companies to "never fly with a common cold".

Ventilator-associated pneumonia (VAP) rates remain highest among trauma and brain injured patients; yet, no research compares VAP risk factors between the 2 groups. This retrospective, case-controlled study identified risk factors for VAP among critically ill trauma patients with and without brain injury. Data were abstracted on trauma patients with (cases) and without (controls) brain injury. Data gathered on n = 157 subjects. Trauma patients with brain injury had more emergent and field intubations. Age was strongest predictor of VAP in cases, and ventilator days predicted VAP in controls. Trauma patients with brain injury may be at higher risk for VAP.

A 3-month-old infant sustained trauma to the mandibular symphysis resulting in radiographic evidence of a fracture of the right condylar head. This presented the diffculty of performing a clinical examination and total reliance on history of a trauma and subsequent swelling. Multiple radiographs of the condyles were used to establish the diagnosis and rule out a film artifact. No definitive treatment was required other than muscle exercises and parental instruction as to potential problems.

Skateboarding injuries: An updated review.

PubMed

Shuman, Kristin M; Meyers, Michael C

2015-07-01

This in-depth literature review shows that skateboarding has experienced intermittent periods of popularity, with an estimated 6-15 million skateboarders in the US currently involved at all levels of recreational play and competition. Head trauma accounts for ∼ 3.5-13.1% of all skateboarding injuries. Injury occurs most often to the upper extremity (55-63%), whereas thoracoabdominal and spine injuries account for 1.5-2.9% of all trauma and lower extremity injuries occur 17-26% of the time. Few fatal injuries (1.1%) have been reported, oftentimes resulting from traumatic head injuries incurred from collisions with motor vehicles. Although skateparks may be perceived as a safer alternative to street skateboarding, injuries still occur when the skateboarder collides with an object or falls from the board. Factors leading to trauma include fatigue and overuse, age and skill level, inadequate medical care, environmental conditions, equipment concerns, lack of fitness and training, and the detrimental behavior of the competitor. Although not all skateboarding injuries are avoidable, numerous opportunities exist to instill safety involving education, instruction, and supervision and the proper use of protective gear to reduce predisposition to trauma. Future research recommendations include a more standardized data collection system, as well as an increased focus on kinetic analysis of the sport. Legislation involving helmet laws and the increased investment in a safer environment for the skateboarder may also assist in reducing injury in this sport.

Morbidity following Mexico City's 1985 earthquakes: clinical and epidemiologic findings from hospitals and emergency units.

1989-01-01

Medical records of 822 inpatients and outpatients cared for by the Department of the Federal District medical services during the 1985 Mexico City earthquakes were reviewed. Record incompleteness varied between 92.8 percent and 14.0 percent for the various study variables. No gender differences were detected among the groups; more than 70.0 percent of the patients were ages 15 to 64 years. Multiple traumatic injuries were frequent for inpatients across age groups, while simple contusions were more frequent among outpatients. Multiple head traumas, thorax-abdomen multiple traumas, and simple fractures of an arm or leg were more frequently recorded for inpatients than for outpatients. Head wounds with contusions; simple contusion of the thorax-abdomen, arms, and legs; and psychological trauma were more frequently recorded for outpatients. Although a great many records were incomplete, the data may reflect what actually happened to these patients, given the similarity of the findings with other reports of disasters. Improved record keeping during emergencies is needed to standardize the quantity and the reliability of the data so that statistical and medical care requirements are soundly based. The use of standard questionnaires for data collection is stressed to facilitate the management of clinical and epidemiologic activities. Longitudinal studies are needed to determine patterns of physical injuries, psychological trauma, and survival. PMID:2508177

We aimed to examine the epidemiological characteristics and injury patterns of pediatric trauma in helicopter emergency medical service (HEMS) caused by sports/outdoor activities in alpine environment. This retrospective cohort study analyzed 912 primary HEMS missions for pediatric trauma (0-14 years of age) in Austrian Alps between 1 January 2006 and 30 June 2007. Children were stratified by age into toddlers (3-5 years), children in early (6-9 years), and late school age (10-14 years). The majority of pediatric sports-related trauma in alpine environment was caused by skiing (82.1%; n=749). Pediatric patients were predominately in late school age and boys (72.8%, n=664 and 61.0%, n=556, respectively) and a minority (16.0%, n=146) was severely injured. Overall, fracture (47.0%, n=429), contusion (17.9%, n=163), and traumatic brain injury (17.0%, n=155) were the most common prehospital diagnoses. The most frequent pattern of injury was related to the head/face and spine (36.3%, n=331). The knowledge about epidemiological characteristics of HEMS use for injured children in alpine environment may be essential for training requirements of HEMS crews and operational considerations of HEMS providers. The incidence of head and spinal injuries requires support for initiatives to promote helmet wear and appropriate risk behavior amongst skiers and snowboarders.

We queried our Trauma Quality Improvement Program registry for patients who presented between 6/1/2011 and 9/1/2015 with severe (injury severity score (ISS)>15) blunt traumatic injury during anticoagulant use. Patients were then grouped into those prescribed warfarin and patients prescribed any of the available novel Direct Oral Anticoagulants (DOAC) medications. We excluded severe (AIS≧4) head injuries. There were no differences between DOAC and warfarin groups in terms of age, gender mean ISS, median hospital or intensive care unit lengths of stay, complication proportions, numbers of complications per patient, or the proportion of patients requiring transfusion. Finally, excluding patients who died, the observed proportion of discharge to skilled nursing facility was similar. In our sample of trauma patients, DOAC use was associated with significantly lower mortality (DOAC group 8.3% vs. warfarin group 29.5%, p<0.015). The ratio of units transfused per patient was also lower in the DOAC group (2.8±1.8 units/patient in the DOAC group vs. 6.7±6.4 units per patient in the warfarin group; p=0.001). In conclusion, we report an association with decrease in mortality and a decrease in transfused blood products in severely injured trauma patients with likely minimal or no head injury taking novel DOACs over those anticoagulated with warfarin for outpatient anticoagulation.

Diabetes insipidus is a disease charaterised by increased urine production and thrist. Neurogenic diabetes insipidus following head trauma,autoimmune disease and infection is quite common but diabetes insipidus following thermal burn injury is a rare complication.We should know about this complication as its management need a comprehensive approach for satisfactory outcome. Thermal burn can cause different complications in early post burn period like electrolyte imbalance, dehydration, acute renal failure, but diabetes insipidus is a very rare and unusual complication that may come across in thermal burn. We should be aware about this condition to prevent and treat mortality and morbidity in burn patients. We have reported a case of transient diabetes insipidus in a patient of thermal burn in early post burn period. Patient was treated accordingly, leading to complete recovery.
