Christmas article: High incidence of ponytail in polytraumatised riders.

Introduction Imaging experience made us suspect an overrepresentation of ponytails in riders admitted as polytrauma after falling from their horse. Methods In a single-centre case-control study conducted over three months, we reviewed the records of all admitted polytraumatised patients for trauma mechanism and presence of ponytail on CT. Cerebral CTs were reviewed in the three standard imaging planes using a bone or lung window. Ponytail was diagnosed if most or all of the hair on the head was gathered and secured at the back of the head with a hair tie. Data were analysed with Fisher's exact test. Results Seven female riders (mean age 22 years) were admitted after falling from their horse (study group); six of these riders wore a ponytail. No male riders were admitted. Therefore, only female polytraumatised patients having suffered any other trauma were selected as controls. The control group consisted of 13 patients (mean age 33,5 years), two of whom wore a ponytail. In three controls, all without ponytails, the trauma also had been related to a horse. Thus, horses were involved in 50% of the traumas included in this study. Ponytail was found more frequently in riders admitted after falling from their horse, p less-than 0,005. Conclusion Having an almost circumferential vision, horses may be scared by the sideways swaying of a ponytail worn by their own rider. In riders, ponytails can trigger a sensation of tightness or even headache which may impair focus. Thus, while female riders most likely wear ponytails for practicality, ponytails may increase the risk of accident by affecting rider and horse. Further studies are required to determine if the observed association between ponytails and trauma is causal. Funding none. Trial registration not applicable.

A Comprehensive Analysis of the Radiation Exposure and the Diagnostic Benefit of PanCT in Pediatric Cases with Multiple Trauma.

Background and Objectives: The primary objective of this study was to obtain quantitative data, taking into account the amount of radiation exposure, about the clinical and diagnostic benefit obtained from panCT in pediatric trauma cases. Thus, we aim to create greater awareness in all physicians and primarily emergency medicine physicians regarding correct selection in terms of the patient group where this effective radiological method is to be applied, and to protect children from the adverse effects of radiation. Materials and Methods: The computed tomography (CT) images were retrieved from the hospital radiological archive system (PACS). The effective dose (Ed) was calculated using the standardized method including the tissue weighted parameters. The radiological pathologies determined as a result of CT imaging of the cases were categorized according to clinical significance in accordance with the Modified CT Colonography Reporting and Data System (C-RADS). Results: The data for a total of 268 patients were analyzed, comprising 89 (33.2%) females and 179 (66.8%) males with a mean age of 8.81 ± 5.21 years. The mean Ed was determined to be 18.14 ± 10.44 mSv. The Ed was determined to be statistically significantly higher in the 1-5 years age group than in the 15-18 years age group (p = 0.024). A statistically significant difference was determined between the age groups in terms of the pathologies determined (p = 0.028). Conclusions: In order to prevent performing unnecessary CT imaging, trauma teams in Emergency Departments (ED) should work in harmony and individual decision-making should be based on the severity of the trauma mechanism, the severity of the predicted injury, and the clinical status of the injured child.

Predictors of Adverse Events in the Surgical Treatment of Adult Distal Humerus Fractures.

The purpose of this study was to identify surgical complications after distal humerus fracture fixation as well as correlations between these complications and patient variables. A total of 132 patients underwent open reduction and internal fixation of traumatic distal humerus fractures between October 2011 and June 2018. Included were adult patients who underwent surgical fixation and had more than 6 months of follow-up. Excluded were patients with inadequate radiographic imaging, less than 6 months of follow-up, and previous distal humerus surgery. Multivariate logistic regression models controlling for age and body mass index were used to determine preoperative factors predictive of postoperative complications. A total of 73 patients were included in this analysis. Surgical complications were reported for 17 patients. Reoperation was required for 13 patients. Open injury at presentation was predictive of delayed union. Predictors of subsequent elbow surgery included younger age, polytrauma, open fracture, and ulnar nerve injury at the time of injury. Radial nerve injury at the time of presentation was also a risk factor for postoperative radial nerve symptoms. Predictors of postoperative heterotopic ossification included older age. Thirty-one patients had an olecranon osteotomy during their open reduction and internal fixation and none went on to nonunion. There were 13 patients with ulnar nerve complications. Of these patients, 3 had undergone an ulnar nerve transposition. None of the other studied variables were predictors of complications, malunion, or nonunion at latest follow-up. Although open reduction and internal fixation is effective in treating distal humerus fractures, its complications cannot be overlooked. Open fractures are more likely to go on to delayed union. Ulnar nerve injury, open fracture, and polytrauma were predictive for reoperation. Older patients were less likely to have subsequent surgery but more likely to develop heterotopic ossification. By identifying at-risk patients, managing physicians can better prognosticate and counsel patients on their recovery. [Orthopedics. 2023;46(6):352-357.].

Fixation of humerus shaft fractures in polytrauma patients does not improve short-term outcomes.

BACKGROUND: Surgical fixation of humeral shaft fractures is widely considered a relative indication for polytraumatized patients to improve mobility and expedite care. This study aimed to determine whether operative treatment of humeral shaft fractures improves short term outcomes in polytrauma (PT] patients. METHODS: Using the National Trauma Data Bank, PT patients with humeral shaft fractures were identified from 2010-2015. Three PT groups were analyzed: Group 1 - PT with nonoperative humeral shaft fracture, Group 2 - PT with humeral fixation on Day 1, and Group 3 - PT with humeral fixation on Day 2+. Cox proportional hazards regression models were used to compare discharge timing and days on ventilator and in ICU between the three groups. RESULTS: There were 395 patients in Group 1, 1,346 in Group 2, and 1,318 in Group 3. There were no differences between the three groups when comparing Glasgow Coma Scale (p=0.3]; however, Injury Severity Score and Abbreviated Injury Scale were statistically different (p<0.001]. No differences were found in ICU or ventilator days between the three groups (p=0.2, p=0.5]. For Length of Stay, no difference was observed in Group 1 vs. Group 2 and Group 2 vs. Group 3. However, non-surgical patients were discharged 20% faster than those with Day 1 surgery (p=0.005]. Open fractures were treated one day earlier than closed fractures but discharged one day later (p<0.001]. CONCLUSIONS: This NTDB study demonstrates no differences in length of stay, days in the ICU or on the ventilator in patients with humeral shaft fractures treated non-operatively versus operative fixation. Overall, 44%-58% in all 3 groups had an ISS ≥ 14. Based on these results, we assert that fixation of the humeral shaft provides no short-term benefits in the multiply injured patient.

Terror-related injuries in Somalia: a retrospective cohort of 2426 hospitalized cases along 7 years.

Terrorism-related injuries and deaths have become a major threat to the Somalian population, as in the rest of the world. We aimed to characterize and compare firearm and explosion injuries caused by terrorist acts. This retrospective study reviewed the data of all patients injured by explosions and firearm attacks over seven years. Epidemiological characteristics, injury pattern, severity scores, hospital resource utilization parameters, length of stay, and death rates were evaluated. A total of 2426 patients were injured by 359 explosions and firearm attacks during the study period. Eighty-one percent of the patients (n = 1974) were male, while 19% of the cases were female. Multiple body site injuries occurred more frequently in explosion injuries (75%) than firearm wounds (48%) (P < 0.001). The relative frequency of internal injuries in explosion injuries was higher than in firearm wounds (46.7% vs. 36.2%). Patients injured due to the explosion have a greater rate of severe and critical injuries than those injured by firearms (30.2% vs. 21.2%, P < 0.001). About a quarter (24%) of the patients were hospitalized in the intensive care unit. The inpatient mortality rate was 11.6%. The findings of the study revealed that suicide bombings explosions are associated with multiple body site injuries, a greater rate of severe and critical internal injuries, and a higher mortality rate.

[The nurse facing a polytrauma patient]. / L'infirmière face à un patient polytraumatisé.

A major public health problem, polytrauma is the leading cause of death in the 15-35 age group, 50% of which occurs within the first hour. This is why the initial care of these patients and their rapid referral to a specialized center (trauma center) is so important. The nurse is in the front line of the care system, in tandem with the medical team.

[Tourniquet use in the Helicopter Emergency Medical Service : Analysis based on data of the DRF Luftrettung (German Air Rescue) in the period 2015-2020]. / Der Einsatz von Tourniquets im Rahmen der Luftrettung : Analyse anhand der Daten der DRF Luftrettung im Zeitraum 2015­2020.

BACKGROUND: In 2016 the first German recommendation for the preclinical use of tourniquets was published. Currently little is known of the frequency of the use of tourniquets in the prehospital setting in Germany. This study evaluated how often a tourniquet is used in a civilian German Helicopter Emergency Medical Service (HEMS). METHOD: After the approval of the scientific working group of the DRF Luftrettung HEMS, the electronic database (HEMSDER) of the DRF Luftrettung HEMS was analyzed for the period 2015-2020 under the abovementioned question. All patients with a tourniquet application were included in the study and a comparison was made with the total trauma cohort and a subgroup analysis between patients who additionally required airway management and patients without additional airway management in the cohort of tourniquet patients. The analysis was mainly descriptive. Parametric test (t-tests and χ2-tests) were used for group comparison. RESULTS: During the study period 67,321 trauma patients were treated and in 866 (1.3% of all trauma patients) a tourniquet was used. The mean age of these patients was 45.9 years (±19.5 years), 710 (84%) were male, 439 (51%) suffered a monotrauma, 296 (34%) suffered multiple trauma, 339 (38%) required a prehospital airway management and 321 (37%) of these were intubated. Significant differences between patients with tourniquet application and the rest of the trauma cohort were detected in general data (monotrauma, polytrauma and high-speed trauma, massive bleeding), vital signs at the scene of the accident (GCS, HF, SpO2) and necessary interventions, such as pressure bandages and use of hemostyptics, tranexamic acid, analgesia, the frequency of intubation and colloidal volume replacement. Due to limitations of the data set we could not obtain information regarding the limb used for the tourniquet, whether a conversion of the tourniquet was carried out and if the tourniquet was used according to the current German trauma guidelines. CONCLUSION: With a frequency of 1.3% the need for a prehospital tourniquet application is low in civilian trauma patients. Monotrauma with isolated extremity injuries represent about half of the patients treated with tourniquets. The other half is represented by multiple injuries or multiple trauma patients who require significantly more invasive measures, such as airway management and more complex on-scene interventions are needed. The available data do not allow any conclusions to be drawn about the location and the quality of the tourniquet application. Future documentation systems should incorporate data on the use of tourniquets, such as the location of use, indications (tactical use/massive bleeding), bleeding control achieved (yes/no) or second tourniquet necessary, conversion (yes/no) and any obvious complications.

The Self-Inflicted Multiple Organs Injury with Nail Gun.

We report the case of a patient with injuries to multiple organs as a result of attempted suicide with a nail gun. The patient shot 12 nails into his chest, causing damage to multiple organs, including the heart, lungs, and stomach. With timely emergency surgery, we successfully removed all the nails, and the patient was discharged from the hospital two weeks after surgery.

Incidence, causes and consequences of moderate and severe traumatic brain injury as determined by Abbreviated Injury Score in the Netherlands.

Traumatic brain injury (TBI) is a leading cause of death and disability. Epidemiology seems to be changing. TBIs are increasingly caused by falls amongst elderly, whilst we see less polytrauma due to road traffic accidents (RTA). Data on epidemiology is essential to target prevention strategies. A nationwide retrospective cohort study was conducted. The Dutch National Trauma Database was used to identify all patients over 17 years old who were admitted to a hospital with moderate and severe TBI (AIS ≥ 3) in the Netherlands from January 2015 until December 2017. Subgroup analyses were done for the elderly and polytrauma patients. 12,295 patients were included in this study. The incidence of moderate and severe TBI was 30/100.000 person-years, 13% of whom died. Median age was 65 years and falls were the most common trauma mechanism, followed by RTAs. Amongst elderly, RTAs consisted mostly of bicycle accidents. Mortality rates were higher for elderly (18%) and polytrauma patients (24%). In this national database more elderly patients who most often sustained the injury due to a fall or an RTA were seen. Bicycle accidents were very frequent, suggesting prevention could be an important aspect in order to decrease morbidity and mortality.

Patterns and Predictors of Firearm-related Spinal Cord Injuries in Adult Trauma Patients.

INTRODUCTION: Firearm-related spinal cord injuries are commonly missed in the initial assessment as they are often obscured by concomitant injuries and emergent trauma management. These injuries, however, have a significant health and financial impact. The objective of this study was to examine firearm-related spinal cord injuries and identify predictors of presence of such injuries in adult trauma patients. METHODS: This retrospective cohort study examined adult trauma patients (≥16 years) with injuries from firearms included in the 2015 United States National Trauma Data Bank. We performed descriptive and bivariate analyses and compared two groups: patients with no spinal cord injury (SCI) or vertebral column injury (VCI); and patients with SCI and/or VCI. Predictors of SCI and/or VCI in patients with firearm-related injuries were identified using a multivariate logistic regression analysis. RESULTS: There were 34,898 patients who sustained a firearm-induced injury. SCI and/or VCI were present in 2768 (7.9%) patients. Patients with SCI and/or VCI had more frequently severe injuries, higher Injury Severity Score (ISS), lower mean systolic blood pressure, and lower Glasgow Coma Scale (GCS). The mortality rate was not significantly different between the two groups (14.7%, N = 407 in SCI and/or VCI vs 15.0%, N = 4,811 in no SCI or VCI group). Significant general positive predictors of presence of SCI and/or VCI were as follows: university hospital; assault; public or unspecified location of injury; drug use; air medical transport; and Medicaid coverage. Significant clinical positive predictors included fractures, torso injuries, blood vessel or internal organ injuries, open wounds, mild (13-15) and moderate GCS scores (9 - 12), and ISS ≥ 16. CONCLUSION: Firearm-induced SCI and/or VCI injuries have a high burden on affected victims. The identified predictors for the presence of SCI and/or VCI injuries can help with early detection, avoiding management delays, and improving outcomes. Further studies defining the impact of each predictor are needed.

Evaluation of the gut microbiome in association with biological signatures of inflammation in murine polytrauma and shock.

Severe injuries are frequently accompanied by hemorrhagic shock and harbor an increased risk for complications. Local or systemic inflammation after trauma/hemorrhage may lead to a leaky intestinal epithelial barrier and subsequent translocation of gut microbiota, potentially worsening outcomes. To evaluate the extent with which trauma affects the gut microbiota composition, we performed a post hoc analysis of a murine model of polytrauma and hemorrhage. Four hours after injury, organs and plasma samples were collected, and the diversity and composition of the cecal microbiome were evaluated using 16S rRNA gene sequencing. Although cecal microbial alpha diversity and microbial community composition were not found to be different between experimental groups, norepinephrine support in shock animals resulted in increased alpha diversity, as indicated by higher numbers of distinct microbial features. We observed that the concentrations of proinflammatory mediators in plasma and intestinal tissue were associated with measures of microbial alpha and beta diversity and the presence of specific microbial drivers of inflammation, suggesting that the composition of the gut microbiome at the time of trauma, or shortly after trauma exposure, may play an important role in determining physiological outcomes. In conclusion, we found associations between measures of gut microbial alpha and beta diversity and the severity of systemic and local gut inflammation. Furthermore, our data suggest that four hours following injury is too early for development of global changes in the alpha diversity or community composition of the intestinal microbiome. Future investigations with increased temporal-spatial resolution are needed in order to fully elucidate the effects of trauma and shock on the gut microbiome, biological signatures of inflammation, and proximal and distal outcomes.

Comparative analysis of two different Turkish hospital reports on polytrauma patients with thoracic trauma.

BACKGROUND: The present study aims to assess whether there are any differences in the management and outcome of polytrauma patients with thoracic trauma in trauma units of two different hospitals in the same country; one hospital is near the Syrian border. METHODS: A retrospective analysis (January 2012 to January 2014) of 348 polytrauma casualties with thoracic trauma from Manisa Celal Bayar University Hospital (MH) were compared according to age, gender, mechanism of injury, associated injuries, abbreviated injury scale (AIS), injury severity score (ISS), treatment modalities, and mortality with 917 patients of Sanliurfa Training and Research Hospital (SH) registry (near the Syrian border). RESULTS: Of the 348 patients in the MH, 230 (66%) and of the 917 patients in the SH, 697 (76%) were males (p<0.001). Mean age was 45.6±18.3 yrs in the MH group and 26.4±22.4 yrs in the SH group (p<0.001). The SH patients had a larger proportion of stab wounds (MH; 9% vs. SH; 17%, p<0.05), gunshot injuries (MH; 5% vs. SH; 18%, p<0.05), higher mean ISS (MH; 30.2±8.4 vs. SH; 42.8±10.2, p<0.001), and increased mortality (MH; 2.6% vs. SH; 11.1%, p<0.001). AISabdomen was the highest component in the SH registry (AISabdomen = 4.8±0.7), whereas AIS extremities were the highest component in the MH registry (AISextremities = 3.6±0.2). CONCLUSION: Significantly different demographic features, mechanisms of injury, worse outcomes and higher mortality rates in SH demonstrate and reflect the surgical challenges depending on the combat environment. Two hospitals in Turkey, one seemingly adjacent to a war zone and another with the more standard civilian experience highlight the impact of the Syrian conflict on the Turkish healthcare system.

Injury and treatment patterns of ballistic pelvic fractures by anatomic location.

INTRODUCTION: Pelvic ballistic injuries threaten critical gastrointestinal, vascular, and urinary structures. We report the treatment patterns and injury profiles of ballistic pelvic fractures and the association between location of ballistic fractures of the pelvis and visceral injuries. METHODS: A prospectively collected database at an academic level I trauma center was reviewed for clinical and radiographic data on patients who sustained one or more ballistic fractures of the pelvis. Main outcomes compared included: procedures with orthopedic surgery, emergent surgery, concomitant intrapelvic injuries, and mortality. RESULTS: Eighty-six patients were included. Eight patients (9.3%) underwent surgical debridement with orthopedic surgery, no ballistic pelvic fractures required surgical stabilization. The anatomical locations of ballistic pelvic fractures included: 10 (14.7%) anterior ring, 13 (19.1%) posterior ring, 27 (39.7%) anterior column, and 18 (20.9%) posterior column. There was a statistically significant association between anterior ring and rectal injury. The association between anterior ring injury and bladder injury approached significance. CONCLUSIONS: This case series included 86 patients with a ballistic fracture of the pelvis, none requiring pelvic ring surgical stabilization. The unpatterned behavior of these injuries demands a high suspicion for visceral injury, with special attention to the rectum and bladder in the setting of anterior ring involvement. LEVEL OF EVIDENCE: IV.

Camel-Related Deaths-A Forensic Overview.

ABSTRACT: Camels are ungulates of the genus Camelus and have been used for centuries in parts of Asia and Africa for transport and sustenance. Handling of camels is not without its dangers, and 4 cases from South Australia are reported with a review of lethal camel-related issues. Case 1 is a 56-year-old man who died of multiple blunt force injuries after he had attempted to move a 7-year-old female dromedary (Camelus dromedarius). Case 2 is a 65-year-old woman who was crushed by 1 or more camels that she had been training. Case 3 is a 1-year-old girl who died of blunt craniocerebral trauma after the car in which she was traveling rolled when the driver swerved to avoid a herd of camels that had strayed onto the road. Case 4 is a 66-year-old woman who died of ischemic and hypertensive cardiac disease exacerbated by physical activity while rounding up camels. Deaths associated with camels involve kicking, stomping, kneeling or sitting on a victim, or biting and shaking and throwing. Lethal mechanisms include hemorrhage from vascular injuries and internal organ disruption, crush asphyxia, and blunt craniospinal injuries. Death may also follow falls from camels or vehicle collisions. Camels also carry a wide range of zoonotic diseases, the most significant of which is Middle Eastern respiratory syndrome. Handling of camels may also exacerbate underlying organic illnesses such as cardiac disease. Those working with camels should be aware that the size, strength, and temperament of these animals may make them dangerous and that they also carry potentially lethal zoonotic diseases.

Different experimental multiple trauma models induce comparable inflammation and organ injury.

Multiple injuries appear to be a decisive factor for experimental polytrauma. Therefore, our aim was to compare the inflammatory response and organ damage of five different monotrauma with three multiple trauma models. For this, mice were randomly assigned to 10 groups: Healthy control (Ctrl), Sham, hemorrhagic shock (HS), thoracic trauma (TxT), osteotomy with external fixation (Fx), bilateral soft tissue trauma (bsTT) or laparotomy (Lap); polytrauma I (PT I, TxT + HS + Fx), PT II (TxT + HS + Fx + Lap) and one multi-trauma group (MT, TxT + HS + bsTT + Lap). The inflammatory response and organ damage were quantified at 6 h by analyses of IL-6, IL-1ß, IL-10, CXCL1, SAA1, HMGB1 and organ injury. Systemic IL-6 increased in all mono and multiple trauma groups, while CXCL1 increased only in HS, PT I, PT II and MT vs. control. Local inflammatory response was most prominent in HS, PT I, PT II and MT in the liver. Infiltration of inflammatory cells into lung and liver was significant in all multiple trauma groups vs. controls. Hepatic and pulmonary injury was prominent in HS, PT I, PT II and MT groups. These experimental multiple trauma models closely mimic the early post-traumatic inflammatory response in human. Though, the choice of read-out parameters is very important for therapeutic immune modulatory approaches.

Characteristics and outcomes of paediatric patients admitted to a Danish level-1 trauma centre.

INTRODUCTION: This study sought to expand the very limited data on Scandinavian paediatric poly-trauma patients by charactering patients from this population admitted to a Danish level-1 trauma centre. METHODS: This retrospective cohort study included all patients 15 years or younger who were admitted to the trauma centre at Aarhus University Hospital, Denmark from January 2000 to May 2014. Injury severity was calculated using the Injury Severity Score (ISS). The Wilcoxon rank-sum test was used to determine significant differences between sexes. RESULTS: A total of 880 children (499 boys and 391 girls) were included. No significant sex-related differences were observed in the numbers admitted during the study period, age at admission or severity of injuries. Overall, 30% of the paediatric patients were admitted in the afternoon (3-6 p.m.). The crude death rate was 2.7% of all admissions. Traffic accidents accounted for 48% of all admissions and two-thirds of all deaths. All non-survivors received ISSs of 16 or higher, and 20% of deaths in this group and 42% of overall deaths occurred within the first 24 hours. CONCLUSIONS: Our study suggests that in Denmark, children admitted to a trauma centre are most likely to have been injured in traffic accidents and/or in the afternoon. Deaths were few and limited to the severely injured children; many survived despite severe injuries. FUNDING: none. TRIAL REGISTRATION: not relevant.

Initial Evaluation and Classification of Knee Dislocations.

The traumatic knee dislocation (KD) is a complex condition resulting in injury to >1 ligament or ligament complexes about the knee, termed multiligament knee injuries. Typically, KDs result in injury to both cruciate ligaments with variable injury to collateral ligament complexes. Very rarely, KD may occur with single cruciate injuries combined with collateral involvement but it is important to understand that not all multiligament knee injuries are KDs. Patients can present in a wide spectrum of severity; from frank dislocation of the tibiofemoral joint to a spontaneously reduced KD, either with or without neurovascular injury. The initial evaluation of these injuries should include a thorough patient history and physical examination, with particularly close attention to vascular status which has the most immediate treatment implications. Multiple classification systems have been developed for KDs, with the anatomic classification having the most practical application.

Combined ACL-PCL-Medial and Lateral Side Injuries (Global Laxity).

The multiple ligament injured knee is a complex problem in orthopedic surgery. These injuries may or may not present as acute knee dislocations, and careful assessment of the extremity vascular and neurological status is essential because of the possibility of arterial and/or venous compromise, and nerve injury. These complex injuries require a systematic approach to evaluation and treatment. Physical examination and imaging studies enable the surgeon to make a correct diagnosis and formulate a treatment plan. Knee stability is improved postoperatively when evaluated with knee ligament rating scales, arthrometer testing, and stress radiographic analysis. Surgical timing depends upon the injured ligaments, vascular status of the extremity, reduction stability, and the overall health of the patient. The use of allograft tissue is preferred because of the strength of these large grafts, and the absence of donor site morbidity.

Independent risk factors for recurrent or multiple new injuries in CrossFit athletes.

BACKGROUND: CrossFit is a relatively new sport with rapidly growing participation rates in the United States and around the world. We sought to determine risk factors for sustaining multiple CrossFit-related injuries requiring medical evaluation. METHODS: CrossFit-related musculoskeletal injuries evaluated at a single hospital system (N.=837) were identified. For musculoskeletal injuries, use of physical therapy, injection, advanced diagnostic imaging including CT or MRI, and surgery were documented. Independent risk factors for sustaining multiple injuries requiring medical evaluation were assessed by multivariate logistic regression analysis. RESULTS: A total of 94/837 (11.2%) underwent evaluation for 2 or more CrossFit-Related injuries (74% new injury to different body part; 26% subsequent injury, same body part). Independent risk factors for repeat injury (recurrent injury or second new injury) included increased length of follow-up (per year: OR 1.50 CI: 1.29, 1.75; P<0.001), initial injury during spring season (OR 2.03 CI: 1.27, 3.26; P=0.004), advanced imaging not obtained for evaluation of initial injury (OR 2.62 CI: 1.37, 5.02; P=0.002), course of physiotherapy completed for initial injury (2.00 CI: 1.17, 3.41; P=0.008), corticosteroid injection administered for initial injury (OR 2.43 CI: 1.21, 4.88; P=0.01), and increased age (per 5 year increase: OR 1.12 CI: 1.01, 1.24; P=0.03). These risk factors in combination had moderate discriminatory ability for identifying athletes at risk for multiple injuries. CONCLUSIONS: There are multiple risk factors for sustaining a recurrent or second new CrossFit-related injury requiring medical evaluation including older age, length of participation, and spring season participation. Risk factors for repeat injury related to initial evaluation and treatment include not receiving advanced imaging, receiving a corticosteroid injection, or undergoing physical therapy. The anatomic site of initial injury was not related to risk of subsequent injury in this population.

A four-year-old Nigerian boy with battered child syndrome: implications for public health.

Battered child syndrome (BCS) is a form of physical abuse that is characterised by multiple injuries and potentially fatal outcome. Despite the high prevalence of physical abuse in developing countries, BCS is rarely reported. Hence, this report highlighted a four-year-old Nigerian boy who suffered multiple injuries (scalp haematoma, bruises, right clavicular fracture, and burns) from the paternal uncle's wife. This case report is discussed along the line of public health approach for curbing the social menace.
