Driveway crush injuries in young children: a highly lethal, devastating, and potentially preventable event

BACKGROUND/PURPOSE: The aim of this study was to investigate driveway-related injuries in children, identify associated risk factors, and evaluate outcome compared with other mechanisms of blunt trauma. METHODS: A 6-year review (1991 to 1996) of pediatric (age less than 18 years) pedestrian injuries treated at two urban trauma centers was conducted: one regional pediatric trauma center and one level I trauma center with pediatric commitment. Five hundred twenty-seven children injured in pedestrian accidents were identified from the trauma registry; 51 children (10%) sustained traumatic injuries as a result of being struck in their driveway. Data are reported as mean +/- SEM. RESULTS: Children less than 5 years of age (n = 41) had an injury severity score (ISS) of 12.3+/-2.3, 15 (37%) sustained closed head injury, 13 (37%) had torso trauma, 19 (46%) skeletal trauma, and eight (20%) died. Children > or = 5 years old (n = 10) had an ISS of 10.7+/-2.4, three (30%) sustained closed head injury, four (40%) torso trauma, six (60%) skeletal trauma, and none died. In contrast, all other pediatric pedestrian accidents analyzed over the same time period had a mortality rate of only 2% (11 of 476). CONCLUSIONS: Pediatric driveway trauma carries a significant risk of head injury and a 10-fold increase in mortality in children under 5 years of age when compared with all other pediatric pedestrian accidents. More emphasis must be placed on injury prevention and public education to prevent this devastating mechanism of injury in these young, vulnerable children.     

Injury panorama and medical consequences for 1158 persons assaulted in the central part of Stockholm, Sweden

This retrospective study describes assaults, type of trauma, injury panorama, the abbreviated injury scale score and medical consequences for 1158 assaulted persons. All patients were examined by surgeons at the Emergency Department, Sabbatsberg's Hospital, Stockholm, Sweden, which is open around the clock. The police were not notified. The study group included all assaulted patients who attended and were examined at the Emergency Department from 1 April 1992 to 31 March 1993: 84% men and 16% women. Their median age was 25 years (range 13-86 years). Sixty-eight percent arrived at the Emergency Department between 11 p.m. and 4 a.m. In 44% the hospital staff registered in the case notes that the victims were drunk. Blunt trauma of low-energy type predominated, 44% were hit by fists and 30% by kicks. Penetrating trauma occurred in 10% of the assaults (knife 8%), and a combination of blunt and/or cutting trauma (bottle/ glass) in 10%. Eighty-two percent of the victims suffered an injury to the head, resulting in concussion in 116 cases, 4 skull fractures, 1 intracerebral contusion, 74 fractures of nose bones, 17 fractures of other face bones, and 6 mandible fractures. Two persons died because of knifestab wounds. Eighty-two percent of the victims had minor injuries, and 16% had moderate injuries according to the score on the Abbreviated Injury Scale (AIS). The present study shows that assault in the central part of Stockholm, Sweden, is mainly a problem involving young men, especially late in the evening, and that many of the victims are drunk. Injuries to the head due to low-energy trauma are the most common (hit by fists and kicks), but severe injuries seldom occur.     

Results of treatment of multiple trauma in 130 children

Trauma remains the leading cause of death in the pediatric age group, despite recent advances in prevention and treatment. We retrospectively analyzed 130 cases of multiple trauma among 725 pediatric patients with injuries treated here during 1988-1989. Road accidents and falls from heights were the most common causes of injury. Mean age was 7 years (range 0.5-15) and the male to female ratio 2.7:1.0. Overall mortality was 9.2%. 57 patients (44%) did not get any prehospital medical care and 5 of them with injury severity scores (ISS) greater than 25 died. In contrast 11/18 (61%) of patients with ISS greater than 25 who were treated by medical teams survived. On arrival at the emergency room, 15% were hypothermic ( < 34 degrees C), and 6 were in hypovolemic shock--5 of whom died. Most common injuries were head trauma (91), limb injuries (69), abdominal trauma (34) and thoracic trauma (34). In 39 injury was severe, with pediatric trauma score (PTS) 6 or less, 12 of whom died. All deaths except 1 were associated with severe head injury and with ISS more than 25. There was no mortality in those with PTS more than 7 or ISS less than 25. Thus, the prehospital care of pediatric patients with head injury is associated with high mortality. Absence of mortality in patients with PTS of more than 7 emphasizes the importance of designated trauma centers for these patients.     

Noninvasive blood glucose monitoring

This prospective review of adult patients with head injuries examines the incidence of head injuries due to falls caused by seizures, the incidence and severity of intracranial hematomas, and the morbidity and mortality rates in this patient population. A head injury was attributed to a fall caused by a seizure if the seizure was witnessed to have caused the fall, or the patient had a known seizure history, appeared postictal or was found convulsing after the fall, and no other cause for the fall was evident. A total of 1760 adult head-injured patients were consecutively admitted to the authors' service between 1986 and 1993. Five hundred eighty-two head injuries (33.1%) were due to falls and 22 (3.8%) of these were caused by seizures. Based on the prevalence rates for epilepsy in the general population of 0.5 to 2%, these results indicate that epileptics are several times more likely to suffer a head injury due to a fall. Mass lesions were found in 20 (90.9%) of these 22 patients and the remaining two patients suffered mild diffuse head injuries. There was a high incidence of extraaxial mass lesions: 17 (85%) of the 20 intracranial hematomas were either epidural (five cases) or acute subdural (12 cases) hematomas. Eighteen (81.8%) of the 22 patients required evacuation of a hematoma. Both the incidence of intracranial hematomas (90.9% vs. 39.8%, p < 0.001, chi-square analysis) and the rate of hematoma evacuation (81.8% vs. 32.3%; p < 0.001) was significantly greater in patients injured in falls due to seizures (22 cases) than in the group injured in falls from all other causes (560 cases). The higher incidence of hematomas and the need for evacuation were not explained by differences in age, seventy of head injury, or incidence of alcohol intoxication. Despite the greater incidence of mass lesions and the need for operative treatment in patients injured because of seizures, their mortality rate was similar to that of patients injured in falls from other causes. On the basis of their review of patients admitted to a neurosurgical center with complaints of head injury, the authors conclude that patients with head injuries due to a fall caused by a seizure should undergo computerized tomography scanning early in their management. Until a mass lesion has been excluded, any decrease in level of consciousness or focal neurological deficit should not be attributed to the seizure itself.     

Profile of pediatric bicycle injuries

BACKGROUND: Bicycle injury data from local communities are important for developing injury prevention and control programs. This study represents the efforts of one community trauma center to describe bicycle injuries. METHODS: We conducted a retrospective analysis of bicycle injury data from hospital charts, emergency medical services reports, and medical examiner reports. The review encompassed a 4-year period. The study sample included 211 trauma alert patients, ages 1 through 15 years, who were treated for bicycle-related injuries at our level II pediatric trauma center. RESULTS: Bicycle injuries accounted for 18% of all pediatric trauma alert patients. The mean age of injured children was 10 years, and 79% were males. Bicycle-motor vehicle collisions caused 84% of injuries. Only 3 children (1.4%) wore bicycle helmets. Resulting injuries included external wounds (86%), head injuries (47%), fractures (29%), and internal organs (9%). Six children died. CONCLUSIONS: Bicycle injuries are a significant cause of mortality and morbidity for children in our community. Use of safety helmets by child bicyclists is inadequate. The data from this study can be used as a baseline in testing the effectiveness of local and state interventions, including new legislation mandating helmet use by children in our state.     

Genetic mapping of the mouse stromal cell-derived factor gene (Sdf1) to mouse and rat chromosomes

OBJECTIVE: To establish the demographics of ski injury in relation to age, gender, and perceived cause during a representative season to identify potential injury prevention strategies. SETTING: Blackcomb Mountain, a world class ski resort in British Columbia, Canada. METHODS: Data were collected from the lift ticket records and from ski patrol injury reports for one season, November to May 1991-2. RESULTS: There were 720,066 skier and snowboarder day visits counted by the mountain's lift ticket records, with a total of 2,092 injury reports (incidence 2.91 per 1,000 day visits). Of those with significant injuries (those requiring physician care), 1,210 (58%) were male. The highest injury rate was among children (age 7-12) and teens (age 13-17) with incidences of 3.18 and 3.34 significant injuries per 1,000 skier days, respectively. Head and face injuries constituted 17% and 22% of injuries, respectively in these groups. Overall 22% of head and face injuries were severe enough to cause loss of consciousness or clinical signs of concussion. This was the body region injured most frequently in males. For females over 7 years of age, the knee was the most common site of injury. For youths, the incidence of injuries during school organized activities was 25% higher than during other outings. CONCLUSIONS: The vulnerability of school group participants suggests special education is warranted. The high incidence of head injuries, particularly among young males, needs to be addressed. In light of the high proportion of this group who already wear helmets, the role of helmets in both protection and possible causation of head injury needs objective research.     

Effects of lead exposure on licking and yawning behaviour in rats

Most studies on facial trauma in the pediatric age group focus on special subgroups. This investigation encompasses all traumatic facial injuries, minor and major, of children and adolescents. Epidemiological data of the type and pattern of injury of trauma patients less than 19 years of age, treated during a 3-year-period in a large metropolitan trauma centre were reevaluated. Of the 1385 patients, 68% had soft tissue injuries, 24% had dental trauma, and 8% fractures of facial bones. More than 90% suffered from minimal or minor trauma. The leading cause of injury was a fall, predominantly at the toddler stage. In adolescents an adult mechanism of trauma prevailed: over 60% of injuries were sequelae of an assault or altercation. The male sex predominated through all age groups and for all types of injuries. The bulk of soft tissue injuries are located within a small falling zone, extending from the nose to the mental area. There was a rising incidence of fractures of facial bones towards older age groups, mandibular fractures being the most common. Condylar fractures, with their potential impact on further growth of the mandible, are seen frequently in children and adolescents, making up 80% of the fractures of the lower jaw.     

Evaluation of alpine skiing and snowboarding injury in a northeastern state

BACKGROUND: To demonstrate the injury patterns of Alpine skiing and snowboarding in a northeastern state and evaluate potential risk factors. METHODS: The medical records of a single pediatric and adult Level I trauma center were evaluated from January 1, 1990, through December 31, 1995. All admissions with injuries caused by Alpine skiing or snowboarding were reviewed. Those patients arriving from two local ski resorts, all of whose injuries are referred to the institution for care, were separated out for consideration. Age, sex, type of injury, date of injury, Injury Severity Score, operations performed, and outcome (including mortality) were evaluated. In addition, resort utilization for the study period was obtained from the two resorts included in the evaluation. Mortality data was obtained from the Vermont office of the Chief Medical Examiner for the same time period. RESULTS: For the 6-year period of the study approximately 2,978,000 skier and snowboarder days were recorded at the study sites. Approximately 447,000 of those days were attributed to snowboarders (15%). In all, 279 patients were admitted for injuries (0.01%), 238 were related to Alpine skiing (incidence 0.01%) and 40 to snowboarding (incidence 0.01%). Snowboarders were statistically younger (20 years; range, 4-44 years) than skiers (29 years; range, 6-70 years) (p < 0.001) and had a significantly lower Injury Severity Score (15 in snowboarders vs. 27 in skiers, p < 0.03). Two female patients were injured snowboarding and 68 female patients were injured skiing. Eight percent of injured snowboarders and 16% of injured skiers sustained multiple injuries (p < 0.01). Injury patterns were significantly different. Upper extremity injuries were almost exclusively found in snowboarders (24% vs. 7%, p < 0.003), whereas cruciate ligament injuries occurred far more commonly in skiers (45% vs. 4%, p < 0.001 Lower extremity injuries in general were more common in skiers (78% vs. 38%, p < 0.001). Central nervous system injuries, including head and spine, were evenly distributed over the two groups, although the snowboarders with central nervous system injuries were younger. In addition, splenic injuries were more common in snowboarders (13% vs. 2%, p < 0.01). Snowboarding accidents were far more common in December, March, and April than other months. Fifty-one patients sustained abdominal or chest injuries and only two of these required operative intervention (two splenectomies). Other operative interventions were limited to extremity injuries, injuries of the spine, or placement of an intracranial pressure monitor. There were no fatalities recorded in this population, although over the 6.5 years, there were 25 deaths related to alpine skiing and one to snowboarding in the State (incidence 0.0000009 skier days). Victims tended to be male: 96% of the skiers and the one snowboarder. The predominant cause of death was blunt head trauma followed by blunt chest trauma. Helmets were not worn by those sustaining head injuries or fatalities. Spine injuries were recorded only in extremely young snowboarders and skiers out of control. CONCLUSION: Snowboarders and Alpine skiers are equally prone to injury. Snowboarding accidents are typically less severe and show significantly different injury patterns than skiing accidents. Abdominal and chest injuries in this population are generally amenable to nonoperative management. Prevention programs are best targeted at safe skiing and snowboarding practices, not skiing or snowboarding in poor conditions, use of helmets for skiers, and restraint of snowboard use in very young children.     

Mild head injury in New Zealand: incidence of injury and persisting symptoms

AIMS: To define mild head injury and determine its incidence and that of persisting symptoms. METHODS: Analysis of an eight week sample of all patients with head injury passing through the Emergency Departments of the four Auckland Hospitals, and of a five year sample of patients attending a clinic for management of symptoms persisting after head injury. RESULTS: Mild head injury was defined by the acute management needed--care out of hospital or not more than 48 hours admission, corresponding reasonably with a definition using post-traumatic amnesia. Incidence in those seen at hospital was 437/10(5) whole population/year for ages 15 and over, and 252/10(5) for ages under 15. Age specific incidences were 1769/10(5)/year for 15 and over, and 2920/10(5) for ages under 15, the major causes being road accidents (RTA) and falls, respectively. For 100 cases seen at hospital approximately 60 were treated by general practitioners alone. Referrals in patients 15 years and over because of persisting symptoms occurred in 5% (95%, CI 3-7), 69% in the first four months and 6% after a year. Referrals were equally likely after RTA, sports injuries and assaults, more frequent after objects striking the head. Older people were marginally more likely to be referred and the probability was significantly greater in women injured in sport and in minor RTA not needing admission to hospital. CONCLUSIONS: Mild head injuries are economically important and deserve efficient management.     

Pediatric all-terrain vehicle trauma: a 5-year statewide experience

BACKGROUND/PURPOSE: This is a retrospective review of the pediatric all-terrain vehicle trauma victims who presented to the five major trauma centers serving the state of West Virginia during the 5-year period from January 1991 to December 1995. The purpose of this research is to characterize the nature of the injuries and the individuals injured to better appreciate the magnitude of the problem of ATV-related injuries in the pediatric population. METHODS: This study is a retrospective review of these 218 consecutive pediatric patients from trauma registry data and their medical records. RESULTS: Two hundred eighteen patients between the ages of 2 years and 16 years presented during the study period. Boys outnumbered girls three to one. The average Injury Severity Score (ISS) was 8.76, the average Glasgow Coma Score (GCS) was 14.4, and the average Trauma Score (TS) was 15.2. The most common injuries were orthopedic followed by head and facial injuries. The majority of the children did not wear helmets, and their injuries resulted in an average hospital length of stay of 4.3 days. Thirty-eight percent of the children required surgery. There were a total of four deaths for a mortality rate of 1.8%. The estimated total hospitalization cost for the 218 patients was $1,918,400.00. CONCLUSIONS: All-terrain vehicle-related trauma remains an ongoing safety concern facing society today. Every physician who cares for children should address this important issue when talking to children and parents about safety issues and injury prevention.     

Diabetic nephropathy and isolated hyporeninemic hypoaldosteronism

OBJECTIVE: 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. DESIGN: 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). MAIN OUTCOME MEASURES: 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. RESULTS: 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. CONCLUSIONS: 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.     

Local anesthetics inhibit the G protein-mediated modulation of K+ and Ca++ currents in anterior pituitary cells

OBJECTIVES: To define the current causes and the optimal methods of early diagnosis and management of ureteric injuries, both iatrogenic (excluding endourologic) and traumatic, and to determine the outcome of these injuries and which identifiable factors affect this outcome. METHODS: A retrospective analysis was performed of all the 35 patients who sustained 40 ureteric injuries over a 5-year period (1991-1996). The methods used for diagnosis and management were reviewed. The outcome was assessed in terms of preservation of renal function. RESULTS: The study group was composed of 28 patients with 32 iatrogenic injuries and 7 patients with 8 injuries caused by external trauma. Gynecologic procedures accounted for 63% (20 of 32) of the iatrogenic injuries, whereas motor vehicle crashes accounted for 75% of the external injuries (6 of 8 injuries). The successful diagnostic rate for direct inspection (intraoperatively), intravenous urogram, retrograde pyelogram, and anterograde pyelogram were 33% for the former two and 100% for the latter two. Treatment consisted of primary open repair in 26 cases, a staged procedure in 7 cases, and endoscopic stenting in 5 cases. Of 36 cases with follow-up, complications developed in 9 cases (25%), 7 cases of which were corrected surgically. Overall incidence of nephrectomy was 8%, and the factors that seemed to affect the outcome adversely were pediatric age (< or =12 years), injury to upper ureter, delay in recognition, the presence of a urinoma, and/or associated organ injury. CONCLUSION: Iatrogenic trauma is the leading cause of ureteric injuries. The single controllable factor adversely affecting the outcome of this rather uncommon injury seems to be delayed diagnosis. Wound inspection and intravenous urogram are not reliable for early and accurate diagnosis, and a retrograde pyelogram or an anterograde pyelogram may be needed. Uncontrollable factors adversely affecting the outcome include young age, injury to upper ureter, and associated injuries all seen in association with external trauma rather than iatrogenic injuries.     

Pediatric penetrating thoracic trauma: a five-year experience

Penetrating thoracic trauma is managed nonoperatively in 85% of adult patients. We hypothesized that similar trauma in children would lead to proportionately more vital tissue damage and a higher rate of operative intervention. The pediatric penetrating thoracic trauma experience of a level one trauma center was analyzed over a five-year period. Data reviewed included circumstances of injury, Pediatric Trauma Score (PTS), interventions performed, and outcome. Of 61 children with thoracic trauma, 13 had penetrating injuries. Of these 13, seven were unintentional (five from firearms); the rest were caused by assaults. Seven patients (54%) underwent thoracotomy or laparotomy. All five patients with a PTS < 8 underwent surgical intervention, whereas only two of the eight patients with a PTS > or = 8 needed surgery (P < 0.05). There was one death. We reached the following conclusions: 1) Children with penetrating thoracic trauma are more likely to require surgical intervention than adults. 2) Penetrating thoracic trauma in children should elicit a thorough search for operative lesions. 3) About half these injuries are unintentional, and thus potentially preventable.     

Diagnosis and management of blunt abdominal trauma

The records of 437 patients with blunt abdominal trauma admitted to Charity Hospital, New Orleans, from 1967-1973 have been reviewed and computer-analyzed. There was an 80% increase in the incidence of blunt abdominal trauma when compared with the preceding 15-year experience. Forty-three per cent of all the patients presented with no specific complaint or sign of injury. Blunt abdominal injury was usually diagnosed preoperatively using conventional methods including history, physical examination, and routine laboratory tests and x-rays. Abdominal paracentesis via a Potter needle had an 86% accuracy. The incidence and management of specific organ injuries with associated morbidity and mortality have been discussed. Mortality and morbidity continue to be significant in blunt abdominal trauma. Isolated abdominal injuries rarely (5%) resulted in death, even though abdominal injuries accounted for 41% of all deaths. Associated injuries, especially head injury, greatly increased the risk. The insidious nature of blunt abdominal injury is borne out by the fact that more than one-third of the "asymptomatic" patients had an abdominal organ injured. A high index of suspicion and an adequate observation period therefore are mandatory for proper care of patients subjected to blunt trauma.     

Nonoperative management of blunt hepatic and splenic injury in children

OBJECTIVE: The authors assessed the risks of nonoperative management of solid visceral injuries in children (age range, 4 months-14 years) who were consecutively admitted to a level I pediatric trauma center during a 6-year period ending in 1991. METHOD: One hundred seventy-nine children (5.0%) sustained injury to the liver or spleen. Nineteen children (11.2%) died. Of the 160 children who survived, 4 received emergency laparotomies; 156 underwent diagnostic computer tomography and were managed nonoperatively. The percentage of children who were successfully treated nonoperatively was 97.4%. Delayed diagnosis of enteric perforations occurred in two children. Fifty-three children (34.0%) received transfusions (mean volume 16.7 mL/kg); however, transfusion rates during the latter half of the study decreased from 50% to 19% in children with hepatic injuries, despite increasing grade of injury, and decreased from 57% to 23% in the splenic group with similar injury grade (p < 0.005, chi square test and Student's t test). CONCLUSION: Pediatric blunt hepatic and splenic trauma is associated with significant mortality. Nonoperative management based on physiologic parameters, rather than on computed tomography grading of organ injury, was highly successful, with few missed injuries and a low transfusion rate.     

Characteristics of pancreatic injury in children: a comparison with such injury in adults

A retrospective study of eight pediatric patients (under 15 years of age) who had pancreatic injuries was undertaken. Comparisons were made with 59 adult patients who sustained pancreatic injuries over the same 15-year period. All the pediatric injuries and 96.6% of the adult resulted from blunt abdominal trauma. Bicycle accidents (children, 75.0%; adults, 0%; P < .001) and automobile accidents (children, 0%; adults, 61.0%; P < .01) were the most common causes of pancreatic injury in the two groups. There was no significant difference in the incidence of abdominal pain or peritoneal irritation between the groups. However, abdominal pain in the adults was poorly localized. Isolated pancreatic injuries were noted in 62.5% of the pediatric patients and in 15.3% of the adult patients (P < .05). Associated intraabdominal injuries were present in 25.0% of the children and in 69.5% of the adults (P < .05). The duodenum was injured in two (25.0%) pediatric patients and in 10 (16.9%) adult patients. Whereas the duodenal injuries in pediatric patients were intramural hematomas without perforation in both cases, all but one of these injuries in adults were perforations or transections (P < .05). There was a significant difference in the type of pancreatic injury between the two groups (P < .05). Surgery was performed in 12.5% of the pediatric cases and in 78.0% of the adult cases (P < .01). There were no deaths among the pediatric patients, but 8.5% of the adults died in the hospital. The difference with respect to clinical course might be related to the differences in cause of injury.     

A comparison of artificially-depleted, lyophilized coumarin and fresh coumarin plasmas in thromboplastin calibration. European Concerted Action on Anticoagulation

BACKGROUND/PURPOSE: Pediatric truncal vascular injuries are rare, but the reported mortality rate is high (35% to 55%), and similar to that in adults (50% to 65%). This report examines the demographics, mechanisms of injury, associated trauma, and results of treatment of pediatric patients with noniatrogenic truncal vascular injuries. METHODS: A retrospective review (1986 to 1996) of a pediatric (< or = 17 years old) trauma registry database was undertaken. Truncal vascular injuries included thoracic, abdominal, and neck wounds. RESULTS: Fifty-four truncal vascular injuries (28 abdominal, 15 thoracic, and 11 neck injuries) occurred in 37 patients (mean age, 14+/-3 years; range, 5 to 17 years); injury mechanism was penetrating in 65%. Concomitant injuries occurred with 100% of abdominal vascular injuries and multiple vascular injuries occurred in 47%. Except for aortic and one SMA injury requiring interposition grafts, these wounds were repaired primarily or by lateral venorrhaphy. Nonvascular complications occurred more frequently in patients with abdominal injuries who were hemodynamically unstable (systolic blood pressure [BPS] <90) on presentation (19 major complications in 11 patients versus one major complication in five patients). Thoracic injuries were primarily blunt rupture or penetrating injury to the thoracic aorta (nine patients). Thoracic aortic injuries were treated without bypass, using interposition grafts. In patients with thoracic aortic injuries, there were no instances of paraplegia related to spinal ischemia (clamp times, 24+/-4 min); paraplegia occurred in two patients with direct cord and aortic injuries. Concomitant injuries occurred with 83% of thoracic injuries and multiple vascular injuries occurred in 25%. All patients with thoracic vascular injuries presenting with BPS of less than 90 died (four patients), and all with BPS 90 or over survived (eight patients). There were 11 neck wounds in 9 patients requiring intervention, and 8 were penetrating. Overall survival was 81%; survival from abdominal vascular injuries was 94%, thoracic injuries 66%, and neck injuries 78%. CONCLUSIONS: Survival and subsequent complications are related primarily to hemodynamic status at the time of presentation, and not to body cavity or vessel injured. Primary anastomosis or repair is applicable to most nonaortic wounds. The mortality rate in pediatric abdominal vascular injuries may be lower than previously reported.     

Pediatric trauma registry: analysis of 1200 cases

OBJECTIVES: We developed the first Spanish Pediatric Trauma Registry in order to collect and evaluate information concerning aspects of injuries in our pediatric population. METHODS: From January'95 to September'97, 28,713 children younger than 16 years were treated in our Hospital for acute injury: 1,200 were admitted and included in our database. Our file-registry consists of 108 data points including: patient identification, type, place and mechanism of injury, pre-hospital care, transport, assessment on admission, severity scores, diagnostic studies, injuries, treatments and morbidity-mortality. RESULTS: Accidents were more frequent in males (69%) than in females. The age-group predominantly was 12-15 years old (34%). Accidents were more frequent in the street (35.3%) than at home (18.7%) or school (14%). Falls and traffic-related accidents were the leading cause of injury (38 and 21.1%, respectively). The 16.7% of cases had Pediatric Trauma Score < or = 8 (n = 201). The 3.6% of this sustained multiple trauma (43 cases with Injury Severity Score > or = 15). Musculoskeletal and head trauma was the most frequent (62 and 42.3%, respectively). Surgical or orthopedic procedures were performed in 678 patients (56.5%). Average length of stay were 4.8 days (range 1-93 days), and functional impairments at discharge were found in 33.9% of patients older than 3 years (n = 338). Mortality rate in our series was 0.5% (n = 6), and 13.9% in children with ISS > or = 15. CONCLUSIONS: The utility of this Registry is to know the epidemiology of our injured pediatric population, to review patient care, to develop prevention programs and to compare results with other centers so potential deficiencies can be identified and corrected.     

The association of patellar ultrasound transmissions and forearm densitometry with vertebral fracture, number and severity: the Saunders County Bone Quality Study

A population survey was conducted to determine the incidence of injuries among preschoolers and their risk factors. A systematic sample (15%, n = 4540) of families with at least one child aged 0-5 years in 1991 living in the Canton of Vaud (Switzerland) received a mailed questionnaire in February 1992. There were 5827 eligible children in the sample. The response rate was 67.5% after two recall mailings. Injuries were defined as those from all causes with at least one physician contact in 1991. The overall incidence was 224 injuries per 1000 children (95% CI [= confidence intervall]: 211-237); 188 per 1000 children were injured over 1 year (95% CI: 176-200, n = 746), of whom 16.5% (n = 123) had 32 injuries. Falls represented 66% of all injuries, followed by burns (8%) and poisonings (5%). The proportion of hospitalized cases was 4.8% and the population incidence of hospitalization due to injury was 10.8/1000 children. Socioeconomic factors did not influence the occurrence of injuries. CONCLUSION: The measured incidence of injuries among preschoolers is among the highest in developed countries. Practitioners could contribute more effectively to injury prevention through routine information and counselling of parents from all social backgrounds.     

Clinicopathologic characteristics of replication error-positive gastric carcinoma

OBJECTIVES: To determine the incidence of skull fracture (SF) and intracranial injury (ICA) among children younger than 2 years evaluated in a pediatric emergency department for head trauma; whether historical features and/or physical findings are predictive of injury type; and whether clinical criteria could allow a selective approach to radiographic imaging. DESIGN: Retrospective medical record review. SETTING: Tertiary pediatric emergency department. PATIENTS: Case series of 278 children aged younger than 24 months evaluated for head injury. MAIN OUTCOME MEASURES: Presence of SF and/or ICA. RESULTS: Diagnoses at discharge included 227 minor head injuries, 39 isolated SF, 9 ICA with SF, and 3 isolated ICA. Children younger than 12 months had the highest incidence of SF/ICA (29%) vs 4% for children aged 13 to 24 months (P<.001). Seven percent of complications from SF/ICA resulted from falls 3 ft (0.9 m) or less [corrected]. Incidence of behavioral change, loss of consciousness, emesis, and seizures did not differ significantly between those with minor head injuries and those with SF/ICA. Scalp abnormalities were more common in children with SF/ICA (P<.001). Sixty-two percent of children with isolated SF and 58% of children with ICA had no history of loss of consciousness, emesis, seizure, or behavioral change. Ninety-two percent of children with isolated SF and 75% of children with ICA had normal levels of consciousness and nonfocal neurologic examinations at diagnosis. Among children who fell 3 ft or less (0.9 m) [corrected] and had no loss of consciousness, emesis, seizure, behavioral change, or scalp abnormality, none of 31 (95% confidence interval [CI], 0-0.10) children younger than 24 months and none of 20 (95% CI, 0-0.15) children younger than 12 months had SF/ICA. CONCLUSIONS: Both SF and ICA are common in children younger than 2 years evaluated for head trauma. Children younger than 12 months are at highest risk. Injuries resulted from relatively minor falls and occurred in alert, neurologically normal children. Clinical signs and symptoms were insensitive predictors of SF/ICA; however, a grouping of features (fall < or = 3 ft [0.9 m], no history of neurologic symptoms, and normal scalp physical examination results) identified a subset of children at low risk for complications.
