RESUMO
PURPOSE: To describe and explore the relationship between baseline anxiety, depression and symptom experience in children and youth assessed at a concussion clinic. DESIGN AND METHODS: A retrospective chart review of concussed children and youth referred to a pediatric teaching hospital concussion clinic over a 15-month period was completed. Kutcher Adolescent Depression Scale (KAD-6), General Anxiety Disorder Scale (GAD-7), and the Post-Concussion Symptom Inventory (PCSI) scores were extracted. RESULTS: A total of 155 patients were included. The most common symptoms (PCSI) at baseline were headache, fatigue, and feelings of head pressure. Symptoms were rated as mild to moderate in intensity. Overall, mean depression and anxiety scores were low. The mean anxiety scores, as measured by the GAD-7 (n = 108), was 7.4 (range, 0-24). The mean depression score, as measured by the KAD-6 (n = 94), was 4.7 (range, 0-18). A statistically significant, moderate positive correlation between PCSI scores with KAD-6 scores for male (r = .64, p < .001) and female (r = .61, p < .001) participants was identified. Similarly, a statistically significant, moderate positive correlation between PCSI scores with GAD-7 scores for male (r = .68, p < .001) and female (r = .60, p < .001) participants was identified. PRACTICE IMPLICATIONS: Concussed children may experience a wide array of symptoms, including emotional challenges such as anxiety and depression. Feelings of anxiety and depression may contribute to overall post concussive symptoms in concussed children. The electronic health record can be leveraged to provide important patient data. Clinicians should systematically assess symptoms at each visit in concussed children and youth so that appropriate interventions can be implemented and monitored.

Compared to adults, it has been documented that children are at elevated risk for concussion, repeated concussions, and experience longer recovery times. What is unknown, is whether the developing brain may be injured at differing strain levels. This study examined peak and cumulative brain strain from 20 cases of concussion in both young children and adults using physical reconstructions and finite element modelling of the brain response to impacts. The child group showed lower impact kinematics as well as strain metrics. Results suggest children may suffer concussive injuries with lower brain strains compared to adults.

Second impact syndrome (SIS) is associated with malignant brain swelling and usually occurs in young athletes with one or more prior, recent concussions. SIS is rare and some dispute its existence. We report a case of SIS in Rowan Stringer, age 17, a rugby player who sustained a fatal brain injury despite prompt medical therapy including decompression surgery. The cause of the massive brain swelling was initially unknown. An inquest revealed Rowan's text messages to friends describing symptoms from two prior, recent rugby brain injuries, likely concussions, within 5 days of the fatal blow and confirming the diagnosis of SIS.

The identification of clinical phenotypes may help parse the substantial heterogeneity that characterizes children with concussion. This study used latent class analysis (LCA) to identify discernible phenotypes among children with acute concussion and examine the association between phenotypes and persistent post-concussive symptoms (PPCS) at 4 and 12 weeks post-injury. We conducted LCA of variables representing pre-injury history, clinical presentation, and parent symptom ratings, derived from a prospective cohort, observational study that recruited participants from August 2013 until June 2015 at nine pediatric emergency departments within the Pediatric Emergency Research Canada network. This substudy included 2323 children from the original cohort ages 8.00-17.99 years who had data for at least 80% of all variables included in each LCA. Concussion was defined according to Zurich consensus statement diagnostic criteria. The primary outcome was PPCS at 4 and 12 weeks after enrollment. Participants were 39.5% female and had a mean age of 12.8 years (standard deviation = 2.6). Follow-up was completed by 1980 (85%) at 4 weeks and 1744 (75%) at 12 weeks. LCA identified four groups with discrete pre-injury histories, four groups with discrete clinical presentations, and seven groups with discrete profiles of acute symptoms. Clinical phenotypes based on the profile of group membership across the three LCAs varied significantly in their predicted probability of PPCS at 4 and 12 weeks. The results indicate that children with concussion can be grouped into distinct clinical phenotypes, based on pre-injury history, clinical presentation, and acute symptoms, with markedly different risks of PPCS. With further validation, clinical phenotypes may provide a useful heuristic for clinical assessment and management.

OBJECTIVE: Complications following pediatric cranioplasty after craniectomy with either autologous bone flaps or cranial implants are reported to be common, particularly bone flap resorption. However, only sparse data are available regarding cranioplasty strategies, complications, and outcomes. This manuscript describes a Canadian-Dutch multicenter pediatric cohort study with autografts and cranial implant cranioplasties following craniectomies for a variety of indications. METHODS: The study included all children (< 18 years) who underwent craniectomy and subsequent cranioplasty surgeries from 2008 to 2014 (with a minimum of 1-year follow-up) at four academic hospitals with a dedicated pediatric neurosurgical service. Data were collected regarding initial diagnosis, age, time interval between craniectomy and cranioplasty, bone flap storage method, type of cranioplasty for initial procedure (and redo if applicable), and the postoperative outcome including surgical site infection, wound breakdowns, bone flap resorption, and inadequate fit/disfigurement. RESULTS: Sixty-four patients (46 males, average age 9.7 ± 5.5 years) were eligible for inclusion, with mean follow-up of 82.3 ± 31.2 months after craniectomy. Forty cranioplasties (62.5%) used autologous bone re-implant, 23 (57.5%) of which showed resorption. On average, resorption was documented at 434 days (range 62-2796 days) after reimplantation. In 20 cases, a revision cranioplasty was needed. In 24 of the post-craniectomy cases (37.5%), a cranial implant was used with one of ten different implant types. Implant loosening prompted a complete revision cranioplasty in 2 cases (8.3%). Cranial implants were associated with low morbidity and lower reoperation dates compared to the autologous cranioplasties. CONCLUSION: The most prominent finding in this multicenter cohort study was that bone flap resorption in children remains a common and widespread problem following craniectomy. Cranioplasty strategies varied between centers and evolved over time within centers. Cranial implants were associated with low morbidity and low reoperation rates. Still, longer term and prospective multicenter cohort studies are needed to optimize cranioplasty strategies in children after craniectomies.

Infantile myofibroma is a rare benign mesenchymal tumor that presents as solitary or multiple lesions (myofibromatosis) in the skin, soft tissue, bone, or internal organs. It most commonly affects the head and neck of infants and young children, but it can also affect adults. Intracranial involvement is reported to be extremely rare, and its clinical picture has been poorly characterized. Recently, it has been demonstrated that germline and somatic mutations in the platelet-derived growth factor receptor beta (PDGFRB) are associated with familial infantile myofibromatosis. We report a case of infantile myofibromatosis with predominant posterior fossa extradural involvement in a 14-year-old adolescent girl with a confirmed mutation in the PDGFRB gene.

Background: Hemifacial spasms are involuntary contractions of the muscles of one side of the face. Case Report: Here, we report a 5-year-old female patient with a significant past medical history, including mucopolysaccharidosis type VI, who also presented with hemifacial spasms. Further investigations showed narrowing of skull foramina and hydrocephalus, but no compression of the facial nerve. Carbamazepine was given to the patient, which caused cessation of the spasms. Discussion: Currently, there is no literature discussing the relationship between hemifacial spasms and mucopolysaccharidosis type VI; we have proposed that mucopolysaccharide deposits or dural thickening may contribute to nerve irritation.

Radiation-associated vascular changes most commonly present in the form of stenosis, thrombosis and occlusion. However, development of intracranial aneurysms secondary to radiation is far less common and often manifests with rupture. These aneurysms are difficult to treat and associated with high morbidity and mortality when ruptured compared with saccular aneurysms unrelated to radiation treatment. Both surgical and endovascular options are available for treatment of these aneurysms. We present a young patient with a radiation-induced intracranial pseudoaneurysm arising from the lenticulostriate branch of the left middle cerebral artery (MCA); this developed 1 year 4 months after 59.4 Gy of focused radiation to the suprasellar pilomyxoid astrocytoma. The patient successfully underwent endovascular glue embolization of the aneurysm and occlusion of the lenticulostriate artery after unsuccessful trapping of the aneurysm and occlusion of the parent artery using coils. She developed transient hemiparesis of the right side following the procedure, which was managed conservatively. We performed a complete review of the literature dealing with the radiation-induced intracranial aneurysms, their presentation, treatment and outcome.

OBJECTIVE In children, the repair of skull defects arising from decompressive craniectomy presents a unique set of challenges. Single-center studies have identified different risk factors for the common complications of cranioplasty resorption and infection. The goal of the present study was to determine the risk factors for bone resorption and infection after pediatric cranioplasty. METHODS The authors conducted a multicenter retrospective case study that included all patients who underwent cranioplasty to correct a skull defect arising from a decompressive craniectomy at 13 centers between 2000 and 2011 and were less than 19 years old at the time of cranioplasty. Prior systematic review of the literature along with expert opinion guided the selection of variables to be collected. These included: indication for craniectomy; history of abusive head trauma; method of bone storage; method of bone fixation; use of drains; size of bone graft; presence of other implants, including ventriculoperitoneal (VP) shunt; presence of fluid collections; age at craniectomy; and time between craniectomy and cranioplasty. RESULTS A total of 359 patients met the inclusion criteria. The patients' mean age was 8.4 years, and 51.5% were female. Thirty-eight cases (10.5%) were complicated by infection. In multivariate analysis, presence of a cranial implant (primarily VP shunt) (OR 2.41, 95% CI 1.17-4.98), presence of gastrostomy (OR 2.44, 95% CI 1.03-5.79), and ventilator dependence (OR 8.45, 95% CI 1.10-65.08) were significant risk factors for cranioplasty infection. No other variable was associated with infection. Of the 240 patients who underwent a cranioplasty with bone graft, 21.7% showed bone resorption significant enough to warrant repeat surgical intervention. The most important predictor of cranioplasty bone resorption was age at the time of cranioplasty. For every month of increased age the risk of bone flap resorption decreased by 1% (OR 0.99, 95% CI 0.98-0.99, p < 0.001). Other risk factors for resorption in multivariate models were the use of external ventricular drains and lumbar shunts. CONCLUSIONS This is the largest study of pediatric cranioplasty outcomes performed to date. Analysis included variables found to be significant in previous retrospective reports. Presence of a cranial implant such as VP shunt is the most significant risk factor for cranioplasty infection, whereas younger age at cranioplasty is the dominant risk factor for bone resorption.

BACKGROUND: With a reported incidence of up to 10% compared to all spinal trauma, spinal injuries in children are less common than in adults. Children can have spine fractures with or without myelopathy, or spinal cord injuries without radiological abnormalities (SCIWORA). METHODS: We retrospectively reviewed the cases of children with spinal injuries treated at a level 1 pediatric trauma centre between 1990 and 2013. RESULTS: A total of 275 children were treated during the study period. The mean age at admission was 12 ± 4.5 years, and the male:female ratio was 1.4:1. Spinal injuries were more common in children of ages 12-16 years, with most injuries among ages 15-16 years. The top 3 mechanisms of spinal injury were motor vehicle-related trauma (53%), sports (28%) and falls (13%). Myelopathy occurred in 12% and SCIWORA occurred in 6%. The most common spine levels injured were L2-sacrum, followed by O-C2. Associated injuries, including head injuries (29%), and fractures/dislocations (27%) occurred in 55% of children. Overall mortality was 3%. Surgical intervention was required in 14%. CONCLUSION: The creation of a pediatric spinal injury database using this 23-year retrospective review helped identify important clinical concepts; we found that active adolescent boys had the highest risk of spine injury, that noncontiguous spine injuries occured at a rate higher than reported previously and that nonaccidental spine injuries in children are underreported. Our findings also emphasize the importance of maintaining a higher index of suspicion with trauma patients with multiple injuries and of conducting detailed clinical and radiographic examinations of the entire spine in children with a known spinal injury.
CONTEXTE: Les traumatismes médullaires sont moins fréquents chez l'enfant que chez l'adulte, avec une incidence d'au plus 10 % de tous les cas déclarés. Les enfants peuvent subir des fractures de la colonne vertébrale avec ou sans myélopathie, ou un traumatisme médullaire sans anomalie radiologique visible (SCIWORA). MÉTHODES: Nous avons effectué une analyse rétrospective des cas d'enfants atteints d'un traumatisme médullaire admis dans un centre de traumatologie spécialisé en pédiatrie de niveau 1 entre 1990 et 2013. RÉSULTATS: Au total, 275 enfants ont été traités durant la période de l'étude. L'âge moyen au moment de l'hospitalisation était de 12 ± 4,5 ans, et le ratio garçons:filles était de 1,4:1. Les adolescents de 12 à 16 ans formaient le groupe le plus représenté, et l'incidence de traumatisme la plus élevée a été observée chez les jeunes de 15 et 16 ans. Les 3 mécanismes lésionnels les plus fréquents étaient les accidents de la route (53 %), la pratique d'un sport (28 %) et les chutes (13 %). Le taux d'incidence de la myélopathie était de 12 %, et celui du SCIWORA, de 6 %. La section du rachis touchée le plus fréquemment s'étendait de L2 au sacrum, les vertèbres entre l'occiput et C2 arrivant au deuxième rang. Des lésions concomitantes, dont des blessures à la tête (29 %) et des fractures et luxations (27 %), ont été observées chez 55 % des enfants. Le taux global de mortalité était de 3 %. L'intervention chirurgicale a été nécessaire chez 14%. CONCLUSION: La création à partir de cette étude rétrospective d'une base de données sur les traumatismes médullaires chez l'enfant a mis en évidence quelques constatations cliniques dignes d'intérêt : les garçons adolescents actifs présentent le risque le plus élevé de traumatisme médullaire; les lésions médullaires non contiguës surviennent plus fréquemment que ce qui avait été rapporté précédemment; les traumatismes médullaires non accidentels chez l'enfant sont sous-déclarés. Nos conclusions viennent aussi souligner l'importance de maintenir un indice de suspicion élevé dans le cas de patients atteints de lésions multiples et d'effectuer un examen clinique et radiographique détaillé de la totalité de la colonne vertébrale des enfants ayant une lésion médullaire connue.

IMPORTANCE: Approximately one-third of children experiencing acute concussion experience ongoing somatic, cognitive, and psychological or behavioral symptoms, referred to as persistent postconcussion symptoms (PPCS). However, validated and pragmatic tools enabling clinicians to identify patients at risk for PPCS do not exist. OBJECTIVE: To derive and validate a clinical risk score for PPCS among children presenting to the emergency department. DESIGN, SETTING, AND PARTICIPANTS: Prospective, multicenter cohort study (Predicting and Preventing Postconcussive Problems in Pediatrics [5P]) enrolled young patients (aged 5-<18 years) who presented within 48 hours of an acute head injury at 1 of 9 pediatric emergency departments within the Pediatric Emergency Research Canada (PERC) network from August 2013 through September 2014 (derivation cohort) and from October 2014 through June 2015 (validation cohort). Participants completed follow-up 28 days after the injury. EXPOSURES: All eligible patients had concussions consistent with the Zurich consensus diagnostic criteria. MAIN OUTCOMES AND MEASURES: The primary outcome was PPCS risk score at 28 days, which was defined as 3 or more new or worsening symptoms using the patient-reported Postconcussion Symptom Inventory compared with recalled state of being prior to the injury. RESULTS: In total, 3063 patients (median age, 12.0 years [interquartile range, 9.2-14.6 years]; 1205 [39.3%] girls) were enrolled (n = 2006 in the derivation cohort; n = 1057 in the validation cohort) and 2584 of whom (n = 1701 [85%] in the derivation cohort; n = 883 [84%] in the validation cohort) completed follow-up at 28 days after the injury. Persistent postconcussion symptoms were present in 801 patients (31.0%) (n = 510 [30.0%] in the derivation cohort and n = 291 [33.0%] in the validation cohort). The 12-point PPCS risk score model for the derivation cohort included the variables of female sex, age of 13 years or older, physician-diagnosed migraine history, prior concussion with symptoms lasting longer than 1 week, headache, sensitivity to noise, fatigue, answering questions slowly, and 4 or more errors on the Balance Error Scoring System tandem stance. The area under the curve was 0.71 (95% CI, 0.69-0.74) for the derivation cohort and 0.68 (95% CI, 0.65-0.72) for the validation cohort. CONCLUSIONS AND RELEVANCE: A clinical risk score developed among children presenting to the emergency department with concussion and head injury within the previous 48 hours had modest discrimination to stratify PPCS risk at 28 days. Before this score is adopted in clinical practice, further research is needed for external validation, assessment of accuracy in an office setting, and determination of clinical utility.

BACKGROUND: Thalamic gliomas are rare. The natural history is unpredictable, and the optimal management of these tumors in children is poorly defined. The aim was to identify outcomes, prognostic factors, and response to various modalities of treatment in a relatively large population of pediatric thalamic tumors from many centers within a fairly homogeneous health care system. METHODS: We performed a Canadian multicenter retrospective review of pediatric thalamic tumors presenting during the MRI era (1989-2012). Radiology and pathology were reviewed by central independent reviewers. Paraffin shavings for RNA extraction were taken and tested for fusion events involving KIAA1549:BRAF. Tumors were classified as unilateral or bithalamic based on their origin on imaging. Univariate and multivariate analyses on factors influencing survival were performed. RESULTS: Seventy-two thalamic tumors were identified from 11 institutions. Females represented 53% of the study population, and the mean age at presentation was 8.9 years. Sixty-two tumors were unilateral and 10 bithalamic. Unilateral tumors had a greater propensity to grow inferiorly towards the brainstem. These tumors were predominantly low grade in comparison to bithalamic tumors which were high-grade astrocytomas. The 5-year overall survival was 61 ± 13% for unithalamic tumors compared to 37 ± 32% for bithalamic tumors (p = 0.097). Multivariate analysis indicated tumor grade as the only significant prognostic factor for unithalamic tumors. Six unilateral tumors, all low grade, were BRAF fusion positive. CONCLUSION: Unilateral and bilateral thalamic tumors behave differently. Surgical resection is an appropriate treatment option in unilateral tumors, most of which are low grade, but outcome is not related to extent of resection (EOR). Bilateral thalamic tumors have a poorer prognosis, but the occasional patient does remarkably well. The efficacy of chemotherapy and radiotherapy has not been clearly demonstrated. Novel therapeutic approaches are required to improve the prognosis for malignant unilateral thalamic tumors and bilateral thalamic tumors.

BACKGROUND: Sports are a major cause of concussions, and little is known about the symptom experience and health-related quality of life (HRQL) in children who remain symptomatic for over 3 months following such head injuries. METHODS: A cross-sectional study of children aged 10-18 years was performed who were referred to the Neurosurgery Clinic at our centre following a head injury. Symptom experience was measured using the modified Concussion Symptom Scale, and HRQL was measured using the Pediatric Quality of Life Inventory (PedsQL). The Immediate Postconcussion Assessment and Cognitive Test (ImPACT) was administered to assess neurocognitive and neurobehavioural sequelae. RESULTS: Symptoms with the highest mean symptom scores on a Likert scale of 0-6 in 35 children at the time of assessment included headaches (3.1), poor concentration (2.7), memory problems (2.1), fatigue (2.1) and sensitivity to noise (2.0). Compared with normative data, children in this study had ImPACT summary scores between the 28th and 38th percentiles and a comparably low Cognitive Efficiency Index score. Mean scores for females were consistently statistically significantly lower (p < 0.05) than for males across all of the HRQL domains. Trouble falling asleep and memory problems explained 62% of the variance in the PedsQL total scores. CONCLUSIONS: Children continue to experience many symptoms at least 3 months following sport-related head injuries that significantly impact their HRQL and neurocognitive abilities.

OBJECTIVE: Like many sports involving high speeds and body contact, head injuries are a concern for short track speed skating athletes and coaches. While the mandatory use of helmets has managed to nearly eliminate catastrophic head injuries such as skull fractures and cerebral haemorrhages, they may not be as effective at reducing the risk of a concussion. The purpose of this study was to evaluate the performance characteristics of speed skating helmets with respect to managing peak linear and peak rotational acceleration, and to compare their performance against other types of helmets commonly worn within the speed skating sport. MATERIALS AND METHODS: Commercially available speed skating, bicycle and ice hockey helmets were evaluated using a three-impact condition test protocol at an impact velocity of 4 m/s. RESULTS AND DISCUSSION: Two speed skating helmet models yielded mean peak linear accelerations at a low-estimated probability range for sustaining a concussion for all three impact conditions. Conversely, the resulting mean peak rotational acceleration values were all found close to the high end of a probability range for sustaining a concussion. A similar tendency was observed for the bicycle and ice hockey helmets under the same impact conditions. CONCLUSION: Speed skating helmets may not be as effective at managing rotational acceleration and therefore may not successfully protect the user against risks associated with concussion injuries.

OBJECTIVES: Anxiety modulates symptom perception in adults following concussion, prolonging the time to full recovery. The authors sought to determine whether parental anxiety was associated with persistent postconcussive symptoms (PCS) in their children following concussion. METHODS: A prospective observational cohort with 98 children aged 5 to 17 years following concussion participated from a tertiary pediatric emergency department (ED). The main exposure was parental anxiety at the time of acute presentation following pediatric concussion, measured using the self-administered, validated Spielberger State-Trait Anxiety Inventory-State Anxiety Scale (STAI-S). The primary outcome measured was presence of PCS in the child at 1 month, per the validated Post-Concussive Symptom Inventory (PCSI). Secondary outcome measures included parental anxiety score over time, school absenteeism, and return to sports. Data were collected during the initial ED visit and at 3-day, 7-day, 2-week, 1-month, and 3-month follow-ups. RESULTS: Of 98 children enrolled, 27% (95% confidence interval [CI] = 19% to 36%) developed PCS at 1 month. No significant associations were detected between parental anxiety at the index visits and the number of previous pediatric concussions (p = 0.73), sex (p = 0.61), loss of consciousness (p = 0.43), history of migraines (p = 0.31), or history of anxiety diagnosed in the patients (p = 0.09). A significant association was noted between patient diagnosis of attention deficit hyperactivity disorder (ADHD) and parental anxiety at the index visits (p = 0.001). Parental anxiety at acute presentation was not associated with children's prolonged symptoms at 1 month (p = 0.63). Parental anxiety remained elevated in parents whose children had prolonged symptoms compared to those parents whose children's symptoms resolved (median = 30, interquartile range [IQR] = 22 to 44; and median = 21, IQR = 20 to 25, respectively; p < 0.001). Initial parental anxiety presentation was not associated with school absenteeism (p = 0.23) or not returning to sport or gym class (p = 0.89). There were no significant effects involving ADHD alone (p = 0.44) or together with baseline parental anxiety (p = 0.36 for ADHD and p = 0.55 for anxiety) using logistic regression analysis to examine potential predictive effects of child's ADHD combined with parental anxiety at the index visit on persistent symptoms at 1 month. CONCLUSIONS: Parental anxiety at time of acute presentation does not appear to be associated with prolongation of postconcussive symptoms in their children. However, parents of persistently symptomatic children remain significantly more anxious than those whose children's symptoms have resolved. Future research should attempt to reduce the familial burden of concussion through expectation management strategies.

BACKGROUND: Abdominal pseudocyst (APC) is an uncommon manifestation of a ventriculoperitoneal (VP) shunt that is attributed to an inflammatory response, usually the result of infection. CASE DESCRIPTION: A 13-year-old girl with a VP shunt presented with progressive abdominal distention, pain and vomiting. The shunt was inserted at infancy for congenital hydrocephalus. A shunt infection was treated with externalization of the shunt, antibiotics and subsequent shunt replacement. At the age of four, the shunt was revised for a distal malfunction. Nine years later, abdominal CT and ultrasound demonstrated large multiseptated cysts. The shunt was externalized and 1.8 L of sterile, xanthochromic peritoneal fluid was drained. The cerebrospinal fluid was clear, colorless, acellular and sterile with normal protein and glucose levels. Two days later, the distal portion of the shunt was replaced back into the pleural cavity. Five months later a pleural effusion formed. Thoracentesis was performed and there was no evidence of infection. The shunt was subsequently converted to a ventriculoatrial system. The patient has remained well for over 3.5 years. CONCLUSION: APC represents an important complication of VP shunts, with an unclear etiology that can occur nine years after shunt surgery. This paper presents an update on the management of APCs.
