Conservative treatment in major kidney trauma

The kidney is frequently involved in penetrating abdominal injuries, and less so in closed abdominal traumatism. This paper presents one case of major renal trauma with total renal fracture and development of urinoma that separated both segments that, after a minimally invasive manoeuvre (percutaneous drainage), evolved favourably thus avoiding a surgical procedure which, quite reasonably, would have led to nephrectomy.     

Primary flap closure in complex limb injuries

Free-tissue transfers enable surgeons to reconstruct or salvage limbs injured or amputated in high-energy traumas which result in extensive damage to soft tissue, bone, tendons, vessels and nerves. Primary free-tissue transfer is performed following debridement, bone fixation, and repair of injured structures within 24 hr after injury. Between 1987 and 1996, 57 patients who had complex extremity traumas were treated with primary free-tissue transfer, or free flaps. Long-term follow-up ranged from 4 months to 9 years (median: 4.5 years). No flap failure or serious wound-healing complication occurred using the protocol. Radical debridement and primary free-flap coverage in extensive extremity injuries can salvage limbs, provide improved functional and aesthetic results, and psychologically benefit patients through lowered morbidity. Other benefits include reduced incidence of free-flap failure, postoperative infection, secondary operative procedures, and invalidity, as well as shorter hospital stays, and lowered medical expenses.     

Intra-hepatic post-traumatic cholestasis. Apropos of 22 cases

The authors report 22 observations of patients showing an intra-hepatic cholestasis following a traumatism. The frequency of this complication amounted to about 1.5 p. 100. Among the mechanisms of this cholestasis some factors were kept in mind: 1. the severity of the traumatism; 2. the surgical act; 3. the use of massive transfusions, the polyvisceral complications of the traumatic shock, the infectious complications. The pathophysiology of this cholestasis seems to be in relation to an increase of the production of the conjugated bilirubin. This production is associated with a decrease of the biliary excretion depending essentially on hepatic intracellular injury, secondary to: the hemorragic shock, the anoxia, the surgical intervention, the infection. From these different factors, they draw practical conclusions as much in the diagnosis of cholestasis as in the therapeutics.     

Prenatal detection of double aneuploidy trisomy 10/monosomy X in a liveborn twin with exclusively monosomy X in blood

Needlestick injuries are the most common type of occupational injury among nurses. At least 20 pathogens can be transmitted via a needlestick injury. Needlestick injuries should be reported immediately. Ongoing education of health-care staff is essential to ensure safe practice in the disposal of sharps.     

Communal behaviors and psychological adjustment of family caregivers and persons with spinal cord injury.

Objective: Examined the influence of mutual communal behaviors on the adjustment reported by persons with spinal cord injury (SCI) and their family caregivers. Previous research has found that persons who have a history of mutually communal behaviors in relationships may react differently to relationship changes after an acquired physical disability than dyads with few communal behaviors. Method: Family caregivers and persons with SCI were administered measures of mutual communal behaviors, depression, and life satisfaction. Structural equation modeling was used to test the relations among caregivers' communal behaviors and care recipients' communal behaviors, depression, and life satisfaction. Results: Caregiver and care recipient reports of communal behaviors were not significantly correlated. Significant paths indicated that care recipients' communal behavior scores were positively associated with their life satisfaction, and care recipients' depression was inversely associated with their life satisfaction. Caregivers' communal behavior scores were unrelated to their self-reported adjustment. Conclusions: Caregiver-care recipient dyads may differ in their perceptions of communal behaviors in their relationships. Although care recipient reports of communal behavior may be related to their life satisfaction, communal behaviors may not serve a similar function among caregivers of persons with SCI.

Meniscal injuries associated with acute anterior cruciate ligament tears in alpine skiers

We reviewed the records of 315 patients receiving an arthroscopically assisted stabilizing procedure for an acute anterior cruciate ligament injury incurred while alpine skiing to evaluate associated meniscal injuries. Meniscal injuries were classified by type, location, and treatment of the tear. Of the 317 knees operated on, all demonstrated an anterior cruciate ligament tear at arthroscopy. Ninety-eight percent of the injuries (310) were diagnosed within 3 days of injury, and 97% (307) were reconstructed within 28 days of injury. All tears occurred in the intrasubstance of the ligament; 32% were isolated injuries and 68% were combined with other injuries. In 159 patients with 170 meniscal tears 141 of the tears (83%) were lateral and 29 (17%) were medial. The injury triad of anterior cruciate ligament-medial collateral ligament-lateral meniscus was seen nine times as often as the anterior cruciate ligament-medial collateral ligament-medial mensicus combination.     

Blunt trauma in children: causes and outcomes of head versus extracranial injury

A subset of the National Pediatric Trauma Registry was analyzed to describe causes and outcomes of blunt trauma among children younger than age 15 years. This subset, of 8639 children with blunt trauma, was divided into three groups according to the injured body region: a group with extracranial injury only (ECI) accounted for one half of the population, and the remainder were equally distributed between a group with head injury only (HI) and one with both conditions (ECI + HI). The three groups were compared with respect to demographic characteristics, external cause of injury, injury severity, and outcomes. Falls were the leading cause of injury in the HI group, where children were younger, whereas traffic-related injuries predominated in children with ECI or ECI + HI. Pedestrian injuries accounted for a significant share of poor outcomes. The highest proportions of deaths and severe injuries were observed in the mixed group (ECI +HI), and the lowest, in the ECI group. In contrast, functional impairments at discharge were most frequently noted in the ECI group, where 60% of the children were discharged with at least one impairment. While only 6% of children with HI were discharged with impairment, those affected exhibited more deficits in cognition and behavior, which are expected to persist longer than dysfunction in activities of daily living.     

A review of selected noncontact anterior cruciate ligament injuries in the National Football League

During five football seasons, from 1989 through 1993, 61 surgically proven, noncontact, anterior cruciate ligament injuries, were identified from among 22 National Football League teams. The variables of surface, shoe type, playing conditions, and whether or not the shoe was spatted were identified for each reported injury. Forty noncontact injuries occurred in conventional cleated shoes on natural grass, and 21 occurred on an artificial surface. Almost half of all injuries (47.5%) occurred during game-day exposures despite the fact that the practice versus game-day exposure rate was 5:1. Of these injuries, 95.2% (N = 58) occurred on a dry field. The factors of cleat and shoe type, type of surface (natural versus artificial), surface conditions (wet/dry), and the effect of "spatting" a shoe are presented. The significance of these factors and their likelihood to be associated with injury is analyzed by use of a statistical tool, the incidence density ratio.     

Pancreatic injuries resulting from penetrating trauma: a multi-institution review

Pancreatic injury from penetrating trauma continues to be a source of significant morbidity and mortality, with questions remaining regarding optimal treatment of injuries. Our goal was to evaluate current trends in the operative management of these injuries. Our patient population comprised all patients admitted to one of three Level I trauma centers over an 8-year period that had sustained penetrating pancreatic trauma. The study was a retrospective chart review. Sixty-two patients were identified. All had associated abdominal injuries, with the liver and stomach being the most commonly injured organs. There were 14 deaths (mortality 22.6%), 10 within the first 48 hours due to associated vascular injury. In the 52 patients surviving beyond 48 hours, there were 19 patients with injuries to the main pancreatic duct and 33 with parenchymal injuries only. Pancreatic resection was carried out for all patients with ductal injury except for one, who later required distal pancreatectomy for pseudocyst and pancreatic fistula. Significant pancreatic fistulae developed in five patients, three in patients treated by drainage and two in patients treated by resection. The incidence of fistula formation was significantly higher for drainage versus resection in the patients with ductal injuries. The incidences of other complications were not affected by type of pancreatic injury, associated injuries, or method of management. We conclude that the majority of deaths in patients with penetrating pancreatic trauma are due to associated organ or vascular injuries. Appropriate management of the pancreatic injury can reduce the long-term complications. These results support treating patients with suspected ductal injuries by appropriate resection. Drainage should probably be sufficient for most nonductal pancreatic injuries.     

Special epiphyseal injuries. 5 case examples

In daily practice, the well-proved Salter-Harris-Rang epiphyseal injuries classification is used worldwide and in Hungary as well. Occasionally there are to be seen epiphyseal injuries which cannot be typed by this classification. The Ogden classification of epiphyseal injuries which enlarges the Salter-Harris-Rang classification with 6 subdivisions and 3 more subdivisions is very useful for the classification of such rare epiphyseal injuries. The authors focus one's attention on Ogden IIB type and Ogden VI type injuries on the basis of their own experience. Ogden IIB is often unstable and susceptible to shortening. In Ogden VI type ligamentous instability beside growing disturbance, caused by meta-epiphyseal bone bridge formation, can be seen. The comminuted growing plate injury caused by high energy direct trauma and healed without growing disturbance in their case, is missed in the Ogden classification. The proper classification is a necessary condition of adequate treatment. We recommend the Ogden classification of rare epiphyseal injuries.     

Sports injuries in the game of hurling. A one-year prospective study

A prospective study of hurling injuries was conducted over the 8 months of one season on 74 players. These athletes averaged 4.30 +/- 2.58 hours per week of training and 1.15 +/- 0.21 hours per week of matches. Mean time of injury was 1.20 +/- 2.53 days in the hospital, 20.34 +/- 19.25 days off sport, and 13.34 +/- 17.25 days of restricted activity. Together this injury time amounts to 14.3% of the season. There were 92 match- and 43 training-related injuries, giving 342.47 injuries per 10,000 hours of matches and 43.83 injuries per 10,000 hours of training. Overall, there were 369.9 days of injury per 1000 hours of participation. The most common type of injury was muscle strain (24.4% of the 135 total injuries). The hamstrings was the most common site of strain, accounting for 41% of these injuries. Contusions comprised 16.3% of the injuries and sprains comprised 15.6%. The most frequently injured sites were the finger (13%), hamstrings (12%), back (11%), head (9%), and knee and ankle (9%). Forty-one percent of the injuries were attributed to foul play. The results of the study suggest that the incidence of injuries in hurling is high and may be attributed to poor conditioning, poor protection, and lack of enforcement of the rules.     

Correlates of work injury frequency and duration among firefighters.

This study examined demographic, personality, and economic incentive correlates of workplace injuries suffered by 171 firefighters over a 12-yr period. Results showed that female firefighters experienced more injuries than male firefighters. Several Minnesota Multiphasic Personality Inventory (MMPI) scales (Conversion Hysteria, Psychopathic Deviate, and Social Introversion) were positively related to injury frequency. Regression analyses revealed that age, tenure, gender, marital status, type of injury, and wage variables were significant when predicting the duration of injuries as well as an interaction between marital status and gender. Two MMPI scales (Psychopathic Deviate and Schizophrenia) were also significantly related to injury duration. Indemnity cost estimates were calculated. The results underscore the importance of distinguishing the duration of injury from the occurrence of injury. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Car surfing: an uncommon cause of traumatic injury

Car surfing is an infrequent cause of traumatic injuries treated by emergency physicians. This very dangerous activity can result in serious injury or death. We report 5 cases of injuries caused by car surfing seen at our hospital during 1996 and 1997. All involved head injuries after a fall from a moving motor vehicle. There were 3 male and 2 female patients, and 3 cases were fatal. Health care providers should be aware of this type of injury and support efforts to prevent it.     

Minor head trauma

This article reviews the persisting difficulty and the importance of the diagnosis of minor head trauma. The diagnosis has been complicated by pervasive disagreement regarding diagnostic criteria. This is primarily a result of the fact that evidence for actual injury is hard to obtain in minor cases because most symptoms tend to be subjective and have high base rates in the normal, uninjured population. At the same time, the diagnostic decision has important implications for patients in terms of treatment, expectancy for future function and lifestyle, and compensation for injuries. Decision theory leads us to the awareness of diagnostic errors. In addition to correct determination, the clinician can make an error of not diagnosing an injury when it has in fact occurred or making a positive diagnosis where there is no injury. The optimal strategy is to set the cutoff at the midpoint of these two error probabilities. The clinician may be willing to make one error rather than the other depending on the cost and bias involved. The second error is more likely to be made when the clinician stands as a strong advocate for the patient and willing to provide any help necessary to encourage treatment, give patients a rationale for understanding their symptoms, and help them obtain compensation for injuries. This can also lead to significant overdiagnosis of injury. The first error is more likely to be made when the clinician recognizes the potential for increasing costs to the health-care industry, the court system, and increasing personal injury claims. He or she may also recognize the vulnerability to the risk for symptom invalidity, the perpetuation of patient symptoms through suggestion, and the need for a biologic explanation for life stressors and preexisting emotional and personality constraints. It can be argued that the most objective diagnostic opinion, uninfluenced by the above biases, should ultimately be in the best interest of the patient, the clinician, legal consultants, and society. Based on the findings in this chapter, at least four symptom constellations can be identified. These have differing probabilities for residual symptoms of minor head trauma and include the following: 1. These patients' symptoms clearly meet the criteria from Table 2. This includes several findings from 1 to 10 of Table 1, together with abnormal neuropsychologic testing on the AIR, General Neuropsychological Deficit Scale, or other indicators of diminished cortical integrity. This group of patients shows a very strong probability of having experienced a brain injury and for showing residual symptoms of minor head trauma. 2. These patients have experienced concussional symptoms (e.g., headache, mild confusion, and balance and visual symptoms) that were documented at the time of injury but sustained no or brief (< 15 seconds) LOC or PTA and, therefore, do not qualify for the diagnosis in Table 2. They may still have several symptoms from Table 1, including objective findings from neuroscanning and variable neuropsychologic testing, especially in measures of attention and delayed recall. This group also shows a high probability for residual, unresolved concussional, and related symptoms. 3. These patients may have shown evidence of concussional symptoms at the time of injury, with no or brief LOC, PTA, or other symptoms from Table 1 (1-10). They continue to show persistent symptoms after 6 months to 1 year. With this group, there is a strong probability that emotional, motivational and premorbid personality factors are either causing or supporting these residual symptoms. 4. In these patients, clearly identifiable postconcussive symptoms at the time of injury are not easy to identify, and perhaps headache is the only reported symptom. There was no LOC or PTA, and virtually none of symptoms 1 to 10 in Table 1 are observed. These patients show strong evidence of symptom invalidity on MMPI-2 or other measures, and marked somatoform, depression, anx     

A system for classifying mechanical injuries of the eye (globe). The Ocular Trauma Classification Group

PURPOSE: To develop a classification system for mechanical injuries of the eye. METHODS: The Ocular Trauma Classification Group, a committee of 13 ophthalmologists from seven separate institutions, was organized to discuss the standardization of ocular trauma classification. To develop the classification system, the group reviewed trauma classification systems in ophthalmology and general medicine and, in detail, reports on the characteristics and outcomes of eye trauma, then established a classification system based on standard terminology and features of eye injuries at initial examination that have demonstrated prognostic significance. RESULTS: This system classifies both open-globe and closed-globe injuries according to four separate variables: type of injury, based on the mechanism of injury; grade of injury, defined by visual acuity in the injured eye at initial examination; pupil, defined as the presence or absence of a relative afferent pupillary defect in the injured eye; and zone of injury, based on the anteroposterior extent of the injury. This system is designed to be used by ophthalmologists and nonophthalmologists who care for patients or conduct research on ocular injuries. An ocular injury is classified during the initial examination or at the time of the primary surgical intervention and does not require extraordinary testing. CONCLUSIONS: This classification system will categorize ocular injuries at the time of initial examination. It is designed to promote the use of standard terminology and assessment, with applications to clinical management and research stud ies regarding eye injuries.     

The relationship of caregiver coping to family outcomes during the initial year following pediatric traumatic injury.

This study identified coping strategies associated with caregiver outcomes following pediatric injury and examined injury type as a moderator of coping efficacy. Families of 103 children with traumatic brain injury (TBI) and 71 children with orthopedic injuries were followed prospectively during the initial year postinjury. The groups had comparable preinjury characteristics and hospitalization experiences but differed on neurological insult. In hierarchical regression analyses, acceptance was associated with lower burden and denial was associated with greater distress in both groups. Active coping resulted in higher distress following TBI but not orthopedic injuries. Conversely, the use of humor was related to diminishing distress following TBI but unrelated to distress following orthopedic injuries. Results are discussed in terms of the implications for intervention following TBI. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Circulating factors as markers and mediators of endothelial cell dysfunction in preeclampsia

3 different types of complex spinal trauma are defined: Type I means a multilevel contiguous or non contiguous unstable injury, type II is described as a spinal injury with concomitant thoracic or abdominal lesion, type III stands for the coincidence of spinal injury and polytrauma. Overlapping of different types occurs. Type I: The incidence amounts according a german multicenter study to about 2.5%. Multilevel injuries need to be stabilized for a long distance from posterior. With a thorough analysis the segments to be fused are determined. Type II: The leading thoracic injury is a lung contusion which occurs in up to 50% of the cases. A CT scan of the thorax during the first diagnostic screening is recommended. Early reduction and stabilization from posterior should be aimed at. During the first two weeks anterior procedures are contraindicated. Abdominal injuries are to be found in 3-4% of all spinal injuries. All organs could be affected. A typical constallation is the "seat-belt syndrome" with lesions of the upper abdominal organs and a flexiondistraction injury of the upper lumbar spine. The main problem is to make the diagnosis of both components initially. Most of the patients may be treated in one operation by first taking care of the abdominal injury and than stabilizing the spine. The prognosis of this combination is favorable. Type III: In 17-18% of all polytraumatized patients lesions of the spine are to be diagnosed. From these only one third need surgical care. From 680 patients with operatively treated fractures of the thoracolumbar junction 6.2% were polytraumatized according to the multicenter study mentioned above. The risk of missing a spinal injury in polytrauma totals approximately 20%. Surgical stabilization should be performed in the primary phase (day-1-surgery). Additional injuries, potentially time consuming operations with a high blood loss sometimes necessitate a different approach. Non stabilized spinal injuries apparently do not have the same negative effect on the whole organism as long bone fractures. In the early phase of treatment on the C-spine only anterior procedures and on the thoracolumbar spine only posterior techniques should be applied.     

Active electrode monitoring. How to prevent unintentional thermal injury associated with monopolar electrosurgery at laparoscopy

BACKGROUND: In recent years, the use of minimally invasive surgery (MIS) has expanded to a wide variety of surgical specialties. The increased popularity of the procedure, however, has been accompanied by its share of complications, including trocar lacerations and inadvertent thermal injuries to nontargeted tissues during monopolar electrosurgery. METHODS: A survey on electrosurgical thermal injuries and three case studies are presented. The new technology of active electrode monitoring (AEM) is described. RESULTS: AEM eliminates stray currents generated by insulation failure and capacitive coupling. CONCLUSIONS: To reduce the incidence of injury by monopolar electrosurgery at laparoscopy, there is a need for advanced technology, such as AEM. In addition, laparoscopic surgeons should be encouraged to study the basic concepts of the biophysics of electrosurgery.     

Cervicothoracic vascular injuries

Arterial and venous trauma of the cervicothoracic region continues to present challenging problems for the surgeon, despite advances in vascular diagnostics and surgical technique. Whether due to penetrating or blunt mechanisms, overall incidence of these injuries is low, whereas morbidity and mortality remain high. Despite collective experience from busy trauma centers, there still remain controversies regarding diagnostic evaluation, operative approach, and surgical treatment of these potentially devastating injuries. Therefore, this article compares and contrasts recent literature and controversies surrounding the treatment of cervicothoracic trauma. Pros and cons of duplex ultrasonography and angiography in the diagnosis of carotid and vertebral artery injury are highlighted, and selective versus mandatory neck exploration for zone II penetrating injuries are discussed. Increasing awareness of blunt carotid artery injury is emphasized, including management dilemmas that frequently accompany this type of injury. In addition, we review interventional radiological techniques for the management of vertebral artery injury and surgical approaches for aortic arch branch vessel or major cervicothoracic vein injury.     

Inotropic effects of glyceryl trinitrate and spontaneous NO donors in the dog heart

Facial fractures may portend intracranial and skullbase injury and may lead to rapid compromise of the airway. Primary care physicians may provide emergency care for patients who have sustained facial trauma. After immediate resuscitation and stabilization, management of facial fractures requires knowledge of the anatomy, rapid treatment methods and identification of potential associated injuries for each type of facial fracture. Differentiation between the life-threatening aspects of these injuries and the less urgent, but more apparent, facial injuries will lessen the risk of complications such as bleeding, meningitis and asphyxia. Knowledge of the anatomy of the facial skeleton and of the potential injuries associated with each of the various types of facial fractures will facilitate effective management decisions. Consultation should be sought when functional features are involved or when the injury threatens to produce future cosmetic anomalies.
