Refining the criteria for immediate total-body CT after severe trauma.

OBJECTIVES: Initial trauma care could potentially be improved when conventional imaging and selective CT scanning is omitted and replaced by immediate total-body CT (iTBCT) scanning. Because of the potentially increased radiation exposure by this diagnostic approach, proper selection of the severely injured patients is mandatory. METHODS: In the REACT-2 trial, severe trauma patients were randomized to iTBCT or conventional imaging and selective CT based on predefined criteria regarding compromised vital parameters, clinical suspicion of severe injuries, or high-risk trauma mechanisms in five trauma centers. By logistic regression analysis with backward selection on the 15 study inclusion criteria, a revised set of criteria was derived and subsequently tested for prediction of severe injury and shifts in radiation exposure. RESULTS: In total, 1083 patients were enrolled with median ISS of 20 (IQR 9-29) and median GCS of 13 (IQR 3-15). Backward logistic regression resulted in a revised set consisting of nine original and one adjusted criteria. Positive predictive value improved from 76% (95% CI 74-79%) to 82% (95% CI 80-85%). Sensitivity decreased by 9% (95% CI 7-11%). The area under the receiver operating characteristics curve remained equal and was 0.80 (95% CI 0.77-0.83), original set 0.80 (95% CI 0.77-0.83). The revised set retains 8.78 mSv (95% CI 6.01-11.56) for 36% of the non-severely injured patients. CONCLUSIONS: Selection criteria for iTBCT can be reduced from 15 to 10 clinically criteria. This improves the positive predictive value for severe injury and reduces radiation exposure for less severely injured patients. KEY POINTS: • Selection criteria for iTBCT can be reduced to 10 clinically useful criteria. • This reduces radiation exposure in 36% of less severely injured patients. • Overall discriminative capacity for selection of severely injured patients remained equal.

Short and Long-Term Parental Posttraumatic Stress After a Child's Accident: Prevalence and Associated Factors.

Studies on the long-term prevalence of parental posttraumatic stress symptoms (PTSS) following child accidental injury are scarce, and findings on risk factors vary. In this follow-up study (T2, n = 69) we determined the prevalence of parental PTSS 2-4 years after accidental injury of their child, compared with 3 months after the accident (T1, n = 135). Additionally, we examined the association between parental and child factors and PTSS severity. Children were 8-18 years old at the time of the accident. Parent and child PTSS was assessed by self-report. Other data were retrieved from medical records and a telephone interview. Parental PTSS was 9.6% at T1 and 5.8% at T2. Acute parental stress as measured within 2 weeks of the child's accident was significantly associated with parental PTSS severity (T1 and T2), as was the child's hospitalization of more than 1 day at T1 and the child's permanent physical impairment at T2. To prevent adverse long-term psychological consequences we recommend identifying and monitoring parents at risk and offering them timely treatment.

Long-Term Posttraumatic Stress Following Accidental Injury in Children and Adolescents: Results of a 2-4-Year Follow-Up Study.

In this study, we determined the long-term prevalence of posttraumatic stress disorder (PTSD) in children and adolescents after accidental injury and gained insight into factors that may be associated with the occurrence of PTSD. In a prospective longitudinal study, we assessed diagnosed PTSD and clinically significant self-reported posttraumatic stress symptoms (PTSS) in 90 children (11-22 years of age, 60% boys), 2-4 years after their accident (mean number of months 32.9, SD 6.6). The outcome was compared to the first assessment 3 months after the accident in 147 children, 8-18 years of age. The prevalence of PTSD was 11.6% at first assessment and 11.4% at follow-up. Children with PTSD or PTSS reported significantly more permanent physical impairment than children without. Children who completed psychotherapy had no symptoms or low levels of symptoms at follow-up. Given the long-term prevalence of PTSD in children following accidents, we recommend systematic monitoring of injured children. The role of possible associated factors in long-term PTSS needs further study.

The Association Between Acute Pain and Posttraumatic Stress Symptoms in Children and Adolescents 3 Months After Accidental Injury.

Previous research suggests that acute pain is a risk factor for later posttraumatic stress symptoms (PTSS). In a prospective cohort study, we examined the association between acute pain from accidental injury and PTSS in children and adolescents, taking into account factors potentially related to pain or posttraumatic stress. Participants were 135 children and adolescents, 8-18 years old. We measured the worst experienced pain since the accident took place with a visual analogue scale. Three months after the accident, posttraumatic stress was assessed with a self-report measure. We found a positive association between acute pain and posttraumatic stress. The amount of pain was negatively associated with injury severity in girls and positively associated with the presence of an extremity fracture in boys. In children who reported severe pain, this pain was significantly associated with PTSS and may account for around 10% of the variance in the severity of PTSS. Although the experience of pain is subjective, our study indicates that severe pain is associated with the severity of later PTSS. Timely management of pain according to acute pain protocols in all phases and disciplines after accidental injury is therefore recommended.

A systematic review and meta-analysis of the sinus tarsi and extended lateral approach in the operative treatment of displaced intra-articular calcaneal fractures.

BACKGROUND: The optimal surgical approach for displaced intra-articular calcaneal fractures (DIACF) is subject of debate. The primary aim of this systematic review and meta-analysis was to assess wound-healing complications following the sinus tarsi approach (STA) compared to the extended lateral approach (ELA). Secondary aims were to assess time to surgery, operative time, calcaneal anatomy restoration, functional outcome, implant removal and injury to the peroneal tendons and sural nerve. METHODS: MEDLINE, EMBASE and Cochrane databases were searched for clinical studies comparing the STA and the ELA (until September 2017). RESULTS: Nine studies were included (two randomized controlled trials; seven comparative studies). 326 patients (331 fractures) were treated by the STA and 383 patients (390 fractures) by ELA. Ninety-nine per cent were Sanders type II/III fractures. Wound healing complications in the STA and ELA occurred in 11/331 and 82/390 fractures, respectively. Weighted means were 4.9% and 24.9%, respectively. Meta-analysis showed significantly less wound healing complications in the STA compared to ELA (risk ratio 0.20; 95% CI 0.11-0.36; P<0.00001; I2=0%). In general, time to surgery and operative time were shorter in the STA. Meta-analysis was not possible due to heterogeneity between studies. No differences were found in remaining secondary outcomes. CONCLUSIONS: The STA is associated with significantly less wound healing complications. With similar functional outcome and calcaneal anatomy restoration, the STA may be the preferred approach in the operative treatment of Sanders type II/III DIACF.

Fixation Methods for Calcaneus Fractures: A Systematic Review of Biomechanical Studies Using Cadaver Specimens.

Calcaneal fractures are notoriously difficult to treat and wound complications occur often. However, owing to the rare nature of these fractures, clinical trials on this subject are lacking. Thus, biomechanical studies form a viable source of information on this subject. With our systematic review of biomechanical studies, we aimed to provide an overview of all the techniques available and guide clinicians in their choice of method of fracture fixation. A literature search was conducted using 3 online databases to find biomechanical studies investigating methods of fixation for calcaneal fractures. A total of 14 studies investigating 237 specimens were identified. Large diversity was found in the tested fixation methods and in the test setups used. None of the studies found a significant difference in favor of any of the fixation methods. All tested methods provided a biomechanically stable fixation. All the investigated methods of fixation for calcaneal fractures seem to be biomechanically sufficient. No clear benefit was found for locking plates in the fixation of calcaneal fractures; however, a subtle mechanical superiority might exist compared with nonlocking plates in the case of fractures in osteoporotic bone. Several of the techniques tested would be suitable for a minimal invasive approach. These should be investigated further in clinical trials.

Outcome following osteosynthesis or primary arthrodesis of calcaneal fractures: A cross-sectional cohort study.

BACKGROUND: Calcaneal fractures are uncommon and have a substantial impact on hindfoot function and quality of life. Several surgical treatment options are available; both in surgical approach and type of operation. The aim of this study was to compare functional outcome and quality of life following ORIF and primary arthrodesis. Furthermore, predictors of worse functional outcome were explored. METHODS: A retrospective cross-sectional cohort study was performed in patients with surgical fixation of a calcaneal fracture with a minimum follow-up of 18 months. Patients received ORIF through the 1) Extended Lateral Approach (ELA), 2) Sinus Tarsi Approach (STA) or 3) primary arthrodesis via STA. Participants were presented a questionnaire containing demographics, the AOFAS hindfoot scale, Foot Function Index, SF-36, EQ-5D and patient satisfaction. RESULTS: In total 95 patients participated in this study. The three groups were comparable regarding patient characteristics. A median score of 74.5 points on the AOFAS hindfoot scale and 11.9 on the FFI was found for the entire group. There were no statistically significant differences between patients with ORIF of primary arthrodesis. Patients scored a median of 49.0 on the Physical Component Scale of the SF-36 and 55.4 on the Mental Component Scale. On the EQ-5D patients scored a median of 0.8 points. Again no statistically significant differences were observed between the three subgroups. Socio-economic status was the only statistically significant predictor of worse functional outcome (ß: 4.06, 95% CI: 0.50-7.62) after multivariable analysis. INTERPRETATION: Good midterm outcomes following in terms of functional outcome and in quality of life are observed. We observed no statistical significant difference in functional outcome between patients with ORIF and patients with primary arthrodesis. The only predictor of worse functional outcome is a lower socio-economic status.

Similar Anatomical Reduction and Lower Complication Rates With the Sinus Tarsi Approach Compared With the Extended Lateral Approach in Displaced Intra-Articular Calcaneal Fractures.

OBJECTIVES: To investigate whether the sinus tarsi approach (STA) allows for a similar anatomical reduction of the posterior talocalcaneal facet as the extended lateral approach (ELA) and compare the rate of postoperative wound complications. DESIGN: Retrospective. SETTING: Level 1 trauma center. PATIENTS: All consecutive patients from 2012 to 2015 with a closed displaced intra-articular calcaneal fracture Sanders type II and III surgically treated with the ELA (N = 60) and the STA (N = 65). MAIN OUTCOME MEASUREMENTS: Wound complications, timing of surgery, operative time, length of postoperative hospitalization, and reduction of the posterior facet and calcaneal body. RESULTS: Incidence of wound complications, time to surgery, postoperative duration of hospital admission, and number of hospital admissions because of wound complications were significantly different between the ELA group and STA group. There was no significant difference in restoration of calcaneal anatomy with either approach. Importantly, the STA was performed in a median duration of 105 minutes and the ELA in a median of 134 minutes, accounting for nearly half an hour difference in operating time (P < 0.001). CONCLUSIONS: The largest benefit of the STA was found in the significant reduction in wound complications and operative time, where time to closure may have accounted for the latter difference. This difference was without a compromise in reduction. Additional studies comparing functional outcome, especially rates of subtalar arthrosis, will be needed to determine the long-term benefits of STA. LEVEL OF EVIDENCE: Therapeutic Level III.

Trauma and psychiatric disorders: A systematic review.

BACKGROUND: Suicide is currently a topic of high priority for policy-makers, researchers and clinicians. The World Health Organization estimated 804,000 suicide deaths worldwide in 2012. Some studies that focused on patients with self-inflicted injury revealed that mortality in this group is higher than for patients who sustain unintentional injury. However little is known about the impact of psychiatric disorders on health care resources including length of hospital stay. OBJECTIVES: To determine whether trauma patients with a psychiatric disorder or after attempting suicide are at higher risk of a complicated course than patients without a psychiatric disorder or accidental cause. The secondary objective was to provide an overview of the current literature on the same group of trauma patients with psychiatric comorbidity in regard to mortality rate, length of stay, hospital costs and quality of life. Our primary outcome measure, complicated course, was found to be most clinically relevant. METHODS: We searched PubMed, Embase and PsycInfo electronic databases. All searches were updated to March 2016. The methodological quality was assessed using the QUIPS tool. RESULTS: Our search identified 9284 articles (PubMed 3660, Embase 2590, PsycInfo 3034). Of these, 18 articles were included. Four studies investigated the association between psychiatric disorders and a complicated course after trauma, three found a significant higher risk of complications. Mortality was reviewed in 14 studies, of which seven showed significant higher risk of in-hospital mortality for trauma patients with psychiatric disorder. Eight of nine studies found significant prolonged length of stay for these patients. CONCLUSION: Patients who have a psychiatric disorder or who have attempted suicide are at higher risk of increased in-hospital mortality and prolonged length of stay after sustaining injuries. These patients also tend to be at higher risk of complications after severe trauma, however future research is needed to confirm these potentially important implications. LEVEL OF EVIDENCE: Systematic review, level III.

Pediatric traumatic brain injury affects multisensory integration.

OBJECTIVE: To investigate the impact of pediatric traumatic brain injury (TBI) on multisensory integration in relation to general neurocognitive functioning. METHOD: Children with a hospital admission for TBI aged between 6 and 13 years (n = 94) were compared with children with trauma control (TC) injuries (n = 39), while differentiating between mild TBI without risk factors for complicated TBI (mildRF-; n = 19), mild TBI with ≥1 risk factor (mildRF+; n = 45), and moderate/severe TBI (n = 30). We measured set-shifting performance based on visual information (visual shift condition) and set-shifting performance based on audiovisual information, requiring multisensory integration (audiovisual shift condition). Effects of TBI on set-shifting performance were traced back to task strategy (i.e., boundary separation), processing efficiency (i.e., drift rate), or extradecisional processes (i.e., nondecision time) using diffusion model analysis. General neurocognitive functioning was measured using estimated full-scale IQ (FSIQ). RESULTS: The TBI group showed selectively reduced performance in the audiovisual shift condition (p = .009, Cohen's d = -0.51). Follow-up analyses in the audiovisual shift condition revealed reduced performance in the mildRF+ TBI group and moderate/severe TBI group (ps ≤ .025, ds ≤ -0.61). These effects were traced back to lower drift rate (ps ≤ .048, ds ≤ -0.44), reflecting reduced multisensory integration efficiency. Notably, accuracy and drift rate in the audiovisual shift condition partially mediated the relation between TBI and FSIQ. CONCLUSION: Children with mildRF+ or moderate/severe TBI are at risk for reduced multisensory integration efficiency, possibly contributing to decreased general neurocognitive functioning.

Immediate total-body CT scanning versus conventional imaging and selective CT scanning in patients with severe trauma (REACT-2): a randomised controlled trial.

BACKGROUND: Published work suggests a survival benefit for patients with trauma who undergo total-body CT scanning during the initial trauma assessment; however, level 1 evidence is absent. We aimed to assess the effect of total-body CT scanning compared with the standard work-up on in-hospital mortality in patients with trauma. METHODS: We undertook an international, multicentre, randomised controlled trial at four hospitals in the Netherlands and one in Switzerland. Patients aged 18 years or older with trauma with compromised vital parameters, clinical suspicion of life-threatening injuries, or severe injury were randomly assigned (1:1) by ALEA randomisation to immediate total-body CT scanning or to a standard work-up with conventional imaging supplemented with selective CT scanning. Neither doctors nor patients were masked to treatment allocation. The primary endpoint was in-hospital mortality, analysed in the intention-to-treat population and in subgroups of patients with polytrauma and those with traumatic brain injury. The χ(2) test was used to assess differences in mortality. This trial is registered with ClinicalTrials.gov, number NCT01523626. FINDINGS: Between April 22, 2011, and Jan 1, 2014, 5475 patients were assessed for eligibility, 1403 of whom were randomly assigned: 702 to immediate total-body CT scanning and 701 to the standard work-up. 541 patients in the immediate total-body CT scanning group and 542 in the standard work-up group were included in the primary analysis. In-hospital mortality did not differ between groups (total-body CT 86 [16%] of 541 vs standard work-up 85 [16%] of 542; p=0.92). In-hospital mortality also did not differ between groups in subgroup analyses in patients with polytrauma (total-body CT 81 [22%] of 362 vs standard work-up 82 [25%] of 331; p=0.46) and traumatic brain injury (68 [38%] of 178 vs 66 [44%] of 151; p=0.31). Three serious adverse events were reported in patients in the total-body CT group (1%), one in the standard work-up group (<1%), and one in a patient who was excluded after random allocation. All five patients died. INTERPRETATION: Diagnosing patients with an immediate total-body CT scan does not reduce in-hospital mortality compared with the standard radiological work-up. Because of the increased radiation dose, future research should focus on the selection of patients who will benefit from immediate total-body CT.

Complications of Kirschner Wire Use in Open Reduction and Internal Fixation of Calcaneal Fractures.

The most important goal of surgical management of displaced intra-articular calcaneal fractures is anatomic correction. This reduction is usually stabilized using plate and screw osteosynthesis. In addition, Kirschner wires (K-wires) can be used to maintain the surgical reduction or stability of the construct. In the present study, we evaluated the frequency and type of use of additional K-wires and subsequent migration in the surgical management of displaced intra-articular calcaneal fractures. The data from 279 patients treated surgically from January 1, 2000 to December 31, 2014 in a level 1 trauma center using an extended lateral approach were analyzed after 1 year of follow-up. All postoperative radiographic images were reviewed to identify the cases in which K-wires were used. Data on the number and type of K-wires used, K-wire location, and K-wire migration found on follow-up imaging studies were collected. Of the 279 patients, 69 K-wires had been used in 49 (18%) patients. A total of 25 (36%) lost (buried), 38 (55%) bent, and 6 (9%) unmodified straight K-wires had been placed. Overall, in 4 (5.8%) of 69 K-wires, secondary dislocation was seen. One (4%) of the lost, 3 (50%) of the unmodified, and none of the bent K-wires showed secondary dislocation. K-wire migration was seen in 5.8% of the cases. None of the bent K-wires and only 1 of the lost K-wires had migrated in the present study. These 2 techniques are preferred when using K-wire fixation in the treatment of displaced intra-articular calcaneal fractures. The use of unmodified straight K-wires should be discouraged.

Predictors of Nonunion and Infectious Complications in Patients With Posttraumatic Subtalar Arthrodesis.

OBJECTIVE: The objective of the present study was (1) to identify predictors of both nonunion and postoperative wound infections (POWI) and (2) to assess the union and complication rate following posttraumatic subtalar arthrodesis (STA). DESIGN: Retrospective comparative cohort study. SETTING: Level 1 trauma center. PATIENTS: All consecutive adult patients with STA following traumatic injuries between 2000 and May 2015. INTERVENTION: STA for posttraumatic deformities. MAIN OUTCOME MEASUREMENTS: Union (described as a combination of radiographic signs of osseous bridging and a clinically fused joint) and POWI as classified by the Centers for Disease and Control. RESULTS: A total number of 93 (96 feet) patients met the inclusion criteria. Union was achieved in 89% of patients. For primary, secondary in situ, and secondary correction arthrodesis, these percentages were 94%, 84,% and 90%, respectively (NS). The union rate significantly increased over time (P = 0.02). In 17 patients (18%), a POWI occurred, of which 2 were classified as superficial and 15 as deep POWIs. The POWI rate did not differ between the groups. Alcohol, nicotine, and drug abuse were not significantly associated with the occurrence of POWIs. Patients with an open fracture or an infection following open reduction internal fixation had a greater risk of a POWI following STA (P = 0.03 and P = 0.04, respectively). CONCLUSIONS: We could not identify predictors for nonunion. In 18% of the patients, an infectious complication following surgery occurred. Patients with an open fracture or an infection after primary surgical treatment (ie, open reduction internal fixation) have a higher chance of POWIs following STA. The union rate following posttraumatic STA is 89%. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Functional Outcomes After Temporary Bridging With Locking Plates in Lisfranc Injuries.

The standard operative treatment of Lisfranc fracture dislocations currently consists of open reduction and transarticular fixation. Recently, bridge plating has been used more often. Using joint spanning, the reduced fracture dislocation is temporary stabilized to minimize articular damage. The present study describes the outcomes of patients treated with bridge plating after tarsometatarsal fracture dislocations compared with transarticular screw fixation. A retrospective cohort study was performed. Patients with an isolated tarsometatarsal injury who had been treated operatively from June 2000 to October 2013 were included. The primary functional outcome was measured using the American Orthopaedic Foot and Ankle Society midfoot score and the Foot Function Index. The secondary outcome was patient satisfaction, which was measured using the EuroQol 5 dimensions questionnaire and a visual analog scale. A total of 34 patients were included. Bridge plating was used in 21 patients. In 13 patients, Kirschner wires or transarticular screws or a combination were used. The median follow-up period was 49 (interquartile range 18 to 89) months. The implants were removed in 10 of 13 patients in the transarticular group and 17 of 21 patients in the bridge plating group. The incidence of wound complications was comparable in both groups. The median American Orthopaedic Foot and Ankle Society score was lower in the transarticular group (77 versus 66). The Foot Function Index score was 18 in both groups. Patient satisfaction was 90% in the bridge plating group and 80% in the transarticular group. Bridge plating for Lisfranc injuries led to at least similar results compared with transarticular fixation in terms of functional outcomes and patient satisfaction. Longer follow-up is necessary to determine whether the prevention of secondary damage to the articular surface leads to less post-traumatic arthritis and better functional outcomes.

Predicting loss of height in surgically treated displaced intra-articular fractures of the calcaneus.

PURPOSE: The goal of calcaneal fracture surgery is to restore its anatomy and good foot function. However, loss of height of the subtalar joint can occur post-operatively, as expressed by a decrease in Böhler's angle (BA). The aim of this study was to identify potential factors associated with a post-operative decrease in BA. METHODS: All consecutive adult patients treated with open reduction and internal fixation (ORIF) by an extended lateral approach (ELA) between 2000 and 2013 were retrospectively included. Primary outcome was the occurrence of a calcaneal collapse, defined as a postoperative decrease of ≥10° in BA. The BA was measured pre-operatively, directly following surgery and at one year follow-up. Patient characteristics (body mass index, diabetes mellitus, smoking/alcohol/substance abuse, American Society of Anaesthesiologist classification), fracture classification and treatment characteristics: per-operative increase in BA and occurrence of post-operative wound infection (POWI) were collected. RESULTS: A total of 262 patients with 276 calcaneal fractures were included. A calcaneal collapse occurred in 46 cases (17%). The median preoperative BA, per-operative increase in BA and post-operative decrease in BA were, respectively, 2°, 27° and 4°. A calcaneal collapse was seen more often following a per-operative increase of >25° in BA, but no significant association was found (p = 0.056). Uni- and multivariate analysis showed that patients with substance abuse and those with POWI had significantly more calcaneal collapse (p < 0.05). No association was found between substance abuse and the occurrence of POWI (p = 0.293). CONCLUSIONS: In nearly one in six patients with an intra-articular calcaneal fracture treated with ORIF by an ELA, a post-operative collapse of ≥10° was found during follow-up. Calcaneal collapse was correlated with the occurrence of a POWI and substance abuse.

Impaired Visual Integration in Children with Traumatic Brain Injury: An Observational Study.

BACKGROUND: Axonal injury after traumatic brain injury (TBI) may cause impaired sensory integration. We aim to determine the effects of childhood TBI on visual integration in relation to general neurocognitive functioning. METHODS: We compared children aged 6-13 diagnosed with TBI (n = 103; M = 1.7 years post-injury) to children with traumatic control (TC) injury (n = 44). Three TBI severity groups were distinguished: mild TBI without risk factors for complicated TBI (mildRF- TBI, n = 22), mild TBI with ≥1 risk factor (mildRF+ TBI, n = 46) or moderate/severe TBI (n = 35). An experimental paradigm measured speed and accuracy of goal-directed behavior depending on: (1) visual identification; (2) visual localization; or (3) both, measuring visual integration. Group-differences on reaction time (RT) or accuracy were tracked down to task strategy, visual processing efficiency and extra-decisional processes (e.g. response execution) using diffusion model analysis. General neurocognitive functioning was measured by a Wechsler Intelligence Scale short form. RESULTS: The TBI group had poorer accuracy of visual identification and visual integration than the TC group (Ps ≤ .03; ds ≤ -0.40). Analyses differentiating TBI severity revealed that visual identification accuracy was impaired in the moderate/severe TBI group (P = .05, d = -0.50) and that visual integration accuracy was impaired in the mildRF+ TBI group and moderate/severe TBI group (Ps < .02, ds ≤ -0.56). Diffusion model analyses tracked impaired visual integration accuracy down to lower visual integration efficiency in the mildRF+ TBI group and moderate/severe TBI group (Ps < .001, ds ≤ -0.73). Importantly, intelligence impairments observed in the TBI group (P = .009, d = -0.48) were statistically explained by visual integration efficiency (P = .002). CONCLUSIONS: Children with mildRF+ TBI or moderate/severe TBI have impaired visual integration efficiency, which may contribute to poorer general neurocognitive functioning.

[Falling from a height: Psychiatric comorbidity and complications]. / Vallen van een hoogte: Psychiatrische comorbiditeit en complicaties.

OBJECTIVE: To investigate whether a mental disorder increases the occurrence of complications in patients after 'a fall from a height'. DESIGN: Retrospective descriptive study. METHODS: Data on all patients admitted following a 'fall from a height' in the period 2004-2012 was retrieved from the trauma registry of the Academic Medical Center (AMC) in Amsterdam, the Netherlands. This was combined with data from the National Surgical Complications Registry (LHCR). A chart review was conducted to determine the presence of mental disorders in these patients. Corrected risk ratio for the risk of complications in patients with a psychological disorder was calculated using the Mantel-Haenszel method. RESULTS: A total of 507 patients presented to the emergency department at the AMC following a fall from a height; 147 patients (29%) experienced 1 or more complications and 131 patients (25.8%) had a mental disorder. Complications arose in 60 patients with a mental disorder (45.8%) and in 87 patients (23.1%) without a mental disorder. The corrected risk ratio showed that a mental disorder is a statistically significant independent predictor of complications (risk ratio: 1.58; 95% confidence interval: 1.21-2.06). CONCLUSION: The risk of complications following a fall from a height in patients with a mental disorder is one and a half times higher than in patients without a mental disorder. This mental disorder is a significant independent predictor of a medical complication following a fall from a height.

Pediatric Traumatic Brain Injury and Attention Deficit.

BACKGROUND: We investigated the impact of pediatric traumatic brain injury (TBI) on attention, a prerequisite for behavioral and neurocognitive functioning. METHODS: Children aged 6 to 13 years who were diagnosed with TBI (n = 113; mean 1.7 years postinjury) were compared with children with a trauma control injury (not involving the head) (n = 53). TBI severity was defined as mild TBI with or without risk factors for complicated TBI (mild(RF+) TBI, n = 52; mild(RF-) TBI, n = 24) or moderate/severe TBI (n = 37). Behavioral functioning was assessed by using parent and teacher questionnaires, and the Attention Network Test assessed alerting, orienting, and executive attention. Ex-Gaussian modeling determined the contribution of extremely slow responses (lapses of attention) to mean reaction time (MRT). RESULTS: The TBI group showed higher parent and teacher ratings of attention and internalizing problems, higher parent ratings of externalizing problems, and lower intelligence than the control group (P < .05, d ≥ 0.34). No effect of TBI on alerting, orienting, and executive attention was observed (P ≥ .55). MRT was slower in the TBI group (P = .008, d = 0.45), traced back to increased lapses of attention (P = .002, d = 0.52). The mild(RF-) TBI group was unaffected, whereas the mild(RF+) TBI and moderate/severe TBI groups showed elevated parent ratings of behavior problems, lower intelligence, and increased lapses of attention (P ≤ .03, d ≥ 0.48). Lapses of attention fully explained the negative relation between intelligence and parent-rated attention problems in the TBI group (P = .02). CONCLUSIONS: Lapses of attention represent a core attention deficit in children with mild(RF+) TBI (even in the absence of intracranial pathology) or moderate/severe TBI, and relate to daily life problems after pediatric TBI.
