Abstract
OBJECTIVES Vomiting is common in children after minor head injury. In previous research, isolated vomiting was not a significant predictor of intracranial injury after minor head injury; however, the significance of recurrent vomiting is unclear. This study aimed to determine the value of recurrent vomiting in predicting intracranial injury after pediatric minor head injury. METHODS This secondary analysis of the CATCH2 prospective multicenter cohort study included participants (0-16 years) who presented to a pediatric emergency department (ED) within 24 hours of a minor head injury. ED physicians completed standardized clinical assessments. Recurrent vomiting was defined as ≥ four episodes. Intracranial injury was defined as acute intracranial injury on computed tomography scan. Predictors were examined using chi-squared tests and logistic regression models. RESULTS A total of 855 (21.1%) of the 4,054 CATCH2 participants had recurrent vomiting, 197 (4.9%) had intracranial injury, and 23 (0.6%) required neurosurgical intervention. Children with recurrent vomiting were significantly more likely to have intracranial injury (odds ratio [OR], 2.3; 95% confidence interval [CI], 1.7-3.1), and require neurosurgical intervention (OR, 3.5; 95% CI, 1.5-7.9). Recurrent vomiting remained a significant predictor of intracranial injury (OR, 2.8; 95% CI, 1.9-3.9) when controlling for other CATCH2 criteria. The probability of intracranial injury increased with number of vomiting episodes, especially when accompanied by other high-risk factors, including signs of a skull fracture, or irritability and Glasgow Coma Scale score < 15 at 2 hours postinjury. Timing of first vomiting episode, and age were not significant predictors. CONCLUSIONS Recurrent vomiting (≥ four episodes) was a significant risk factor for intracranial injury in children after minor head injury. The probability of intracranial injury increased with the number of vomiting episodes and if accompanied by other high-risk factors, such as signs of a skull fracture or altered level of consciousness.

J Neurosurg Pediatr 2019; 25:284-290.

Abstract
OBJECTIVE Isolated, nondisplaced skull fractures (ISFs) are a common result of pediatric head trauma. They rarely require surgical intervention; however, many patients with these injuries are still admitted to the hospital for observation. This retrospective study investigates predictors of vomiting and ondansetron use following pediatric ISFs and the role that these factors play in the need for admission and emergency department (ED) revisits. METHODS The authors identified pediatric patients (< 18 years old) with a linear ISF who had presented to the ED of a single tertiary care center between 2008 and 2018. Patients with intracranial hemorrhage, significant fracture displacement, or other traumatic injuries were excluded. Outcomes included vomiting, ondansetron use, admission, and revisit following ED discharge. Both univariable and multivariable analyses were used to determine significant predictors of each outcome (p < 0.05). RESULTS Overall, 518 patients were included in this study. The median patient age was 9.98 months, and a majority of the patients (59%) were male. The most common fracture locations were parietal (n = 293 [57%]) and occipital (n = 144 [28%]). Among the entire patient cohort, 124 patients (24%) had documented vomiting, and 64 of these patients (52%) received ondansetron. In a multivariable analysis, one of the most significant predictors of vomiting was occipital fracture location (OR 4.05, p < 0.001). In turn, and as expected, both vomiting (OR 14.42, p < 0.001) and occipital fracture location (OR 2.66, p = 0.017) were associated with increased rates of ondansetron use. A total of 229 patients (44%) were admitted to the hospital, with vomiting as the most common indication for admission (n = 59 [26%]). Moreover, 4.1% of the patients had ED revisits following initial discharge, and the most common reason was vomiting (11/21 [52%]). However, in the multivariable analysis, ondansetron use at initial presentation (and not vomiting) was the sole predictor of revisit following initial ED discharge (OR 5.05, p = 0.009). CONCLUSIONS In this study, older patients and those with occipital fractures were more likely to present with vomiting and to be treated with ondansetron. Additionally, ondansetron use at initial presentation was found to be a significant predictor of revisits following ED discharge. Ondansetron could be masking recurrent vomiting in ED patients, and this should be considered when deciding which patients to observe further or discharge.

Abstract
Pediatric head injuries are common and may present with varying degrees of altered mental status in children. The approach to evaluation, diagnosis, treatment, and prevention of further injury is important in achieving good health outcomes after a head injury. In this article, we review the pathophysiology, classifications, signs and symptoms, and management of traumatic brain injury. We also discuss the importance of preventing a secondary injury during recovery by educating families about head injury sequelae and return-to-play guidelines. [Pediatr Ann. 2019;48(5):e192-e196.].

Abstract
Background: Computed tomography (CT) used in pediatric pediatrics brain injury (TBI) to ascertain neurological manifestations. Nevertheless, this practice is associated with adverse effects. Reports in the literature suggest incidents of morbidity and mortality in children due to exposure to radiation. Hence, it is found imperative to search for a reliable alternative. Objectives: The aim of this study is to find a reliable clinical alternative to detect an intracranial injury without resorting to the CT. Materials and Methods: Retrospective cross-sectional study was undertaken in patients (1-14 years) with blunt head injury and having a Glasgow Coma Scale (GCS) of 13-15 who had CT performed on them. Using statistical analysis, the correlation between clinical examination and positive CT manifestation is analyzed for different age-groups and various mechanisms of injury. Results: No statistically significant association between parameteres such as Loss of Consciousness, ‘fall’ as mechanism of injury, motor vehicle accidents (MVA), more than two discrete episodes of vomiting and the CT finding of intracranial injury could be noted. Analyzed data have led to believe that GCS of 13 at presentation is the only important clinical predictor of intracranial injury. Conclusion: Retrospective data, small sample size and limited number of factors for assessing clinical manifestation might present constraints on the predictive rule that was derived from this review. Such limitations notwithstanding, the decision to determine which patients should undergo neuroimaging is encouraged to be based on clinical judgments. Further analysis with higher sample sizes may be required to authenticate and validate findings.

Abstract
Vomiting is a protective reflex that results in forceful ejection of stomach contents up to and out of the mouth. It is a common complaint and may be the presenting symptom of several life-threatening conditions. It can be caused by a variety of organic and nonorganic disorders; gastrointestinal (GI) or outside of GI. Acute gastritis and gastroenteritis (AGE) are the leading cause of acute vomiting in children. Important life threatening causes in infancy include congenital intestinal obstruction, atresia, malrotation with volvulus, necrotizing enterocolitis, pyloric stenosis, intussusception, shaken baby syndrome, hydrocephalus, inborn errors of metabolism, congenital adrenal hypoplasia, obstructive uropathy, sepsis, meningitis and encephalitis, and severe gastroenteritis, and in older children appendicitis, intracranial mass lesion, diabetic ketoacidosis, Reye's syndrome, toxic ingestions, uremia, and meningitis. Initial evaluation is directed at assessment of airway, breathing and circulation, assessment of hydration status and red flag signs (bilious or bloody vomiting, altered sensorium, toxic/septic/apprehensive look, inconsolable cry or excessive irritability, severe dehydration, concern for symptomatic hypoglycemia, severe wasting, Bent-over posture). The history and physical examination guides the approach in an individual patient. The diverse nature of causes of vomiting makes a "routine" laboratory or radiologic screen impossible. Investigations (Serum electrolytes and blood gases,renal and liver functions and radiological studies) are required in any child with dehydration or red flag signs, to diagnose surgical causes. Management priorities include treatment of dehydration, stoppage of oral fluids/feeds and decompression of the stomach with nasogastric tube in patients with bilious vomiting. Antiemetic ondansetron(0.2 mg/kg oral; parenteral 0.15 mg/kg; maximum 4 mg) is indicated in children unable to take orally due to persistent vomiting, post-operative vomiting, chemotherapy induced vomiting, cyclic vomiting syndrome and acute mountain sickness.

Abstract
PURPOSE Every year 300,000 children with accidental head trauma are admitted to Italian emergency departments. Our aims were: (1) to describe patients with minor traumatic brain injury who were admitted to pediatric departments and underwent CT, and (2) to analyze the appropriateness of management according to current guidelines. METHODS We retrospectively analyzed patients with minor head injury (median age 4.5 years, range 1 month to 16 years) who were admitted to the pediatric department of the Catholic Medical School of Rome, from January 2005 to September 2010, who performed head CT. Univariate analysis was performed using the Fisher's exact test. Multivariate analysis was performed by logistic regression. RESULTS One hundred and seventy-four patients were enrolled in the study. Fifty-four patients (31%) had pathological CT findings. Eight patients underwent neurosurgical treatments. Vomiting was the only symptom significantly prevalent in the infant group, compared to the children group (10.7% vs. 38.9%, p = 0.007), while loss of consciousness in the children group (50.0% vs. 25.0%, p = 0.040). The relationship between scalp swelling and CT abnormalities was statistically significant in the entire population. The incidence of head abnormalities was significantly higher in children with abnormal CT (92.6% vs. 72.5%). CONCLUSIONS The best way to manage children with minor head trauma is still matter of debate. Loss of consciousness and scalp swelling are risk factors predicting brain injury that deserve CT control. The radiation risks posed by CT scanning in children must be balanced by the benefits. We believe that even though CT scans may be clinically unnecessary in many cases, the rate of scanning is justified by the even limited number of abnormalities which require neurosurgical treatment.

Abstract
OBJECTIVE To study selected factors associated with vomiting after minor head trauma in children. STUDY DESIGN During a 1-year study, 1097 children with a minor head injury were consecutively discharged from the pediatric emergency department; 162 had associated vomiting. A case-control study was conducted, with each subject matched with 2 children of the same age group with a minor head injury who did not have associated vomiting. Final analysis was conducted in 148 case subjects and 296 matched control subjects. RESULTS With univariate analysis, a personal history of recurrent headache (6.1% versus 2.4%), motion sickness (27% versus 11.8%), and recurrent vomiting (6.1% versus 0.7%) were significantly more common in the vomiting group, as was a family history of recurrent headache in parents (45.9% versus 27%) or motion sickness in parents (26.4% versus 15.2%) or siblings (14.2% versus 3.7%). The strongest predictors of vomiting were a personal history of recurrent vomiting (odds ratio, 5.90; 95% CI, 1.18-29.47), motion sickness (odds ratio, 2.34; 95% CI, 1.32-4.10), headache at the time of the injury (odds ratio, 4.37; 95% CI, 2.23-8.57), and a strong family history of the same recurrent problems (odds ratio, 1.66; 95% CI, 1.29-2.13). CONCLUSIONS Post-traumatic vomiting is significantly related to personal or familial predisposition to vomit rather than to the presence of intracranial lesions.

Abstract
UNLABELLED This study was conducted to determine if clinical features can predict the risk of intracranial injury (ICI) in pediatric closed head trauma. We enrolled 3,806 children under 16 years consecutively referred for acute closed head trauma to the paediatric emergency room of five Italian children's hospitals. Relevant outcomes were death and diagnosis of ICI. Clinical symptoms and signs were evaluated as possible outcome predictors. Children were also classified into five groups according to their clinical presentation. The association of ICI with signs and symptoms and the appropriateness of the five-group classification in predicting the likelihood of ICI were evaluated by logistic regression analyses. ICI was diagnosed in 22 children; 2 of them died. The risk of fatal and nonfatal ICI was 0.5 and 5.2 per 1,000 children with closed head trauma respectively. Significant associations were found between ICI and loss of consciousness, prolonged headache, persistent drowsiness, abnormal mental status, focal neurological signs, signs of skull fracture in non-frontal areas and signs of basal skull fracture. The five-group classification of children allowed an excellent prediction in terms of likelihood of ICI (ROC area 0.972). CONCLUSIONS Selection of children with closed head trauma based on different combinations of signs and symptoms allows for early identification of subjects at different risk for ICI. In patients with minor head injuries, the absence of loss of consciousness, drowsiness, amnesia, prolonged headache, clinical evidence of basal or non-frontal skull fracture identified 100% of children without lesions. Validation of our results with a larger sample of patients with ICI would be highly desirable.

Abstract
OBJECTIVES To assess the effect of a change in skull x ray policy on the rate of admission, use of computed tomography (CT), radiation dose per head injury, and detection of intracranial injuries; and to compare the characteristics of patients with normal and abnormal head CT. DESIGN Retrospective cohort study. SETTING UK paediatric teaching hospital emergency department. PATIENTS 1535 patients aged between 1 and 14 years with a head injury presenting to the emergency department between 1 August 1998 and 31 July 1999 (control period), and 1867 presenting between 1 August 2002 and 31 July 2003 (first year of new skull x ray policy). INTERVENTION Hospital notes and computer systems were analysed and data were collected on all patients presenting with a head injury. RESULTS The abolition of skull x rays in children aged over 1 year prevented about 400 normal skull x rays being undertaken in period 2. The percentage of children undergoing CT rose from 1.0% to 2.1% with no change in the positive CT pick up rate (25.6% v 25.0%). There was no significant change in admission rate (10.9% v 10.1%), and a slight decrease in the radiation dose per head injury (0.042 mSv compared to 0.045 mSv). CONCLUSIONS Skull x rays can be abandoned in children aged 1 to 14 without a significant increase in admission rate, radiation dose per head injury, or missed intracranial injury. The mechanism and history of the injury and a reduced Glasgow coma scale are probably the most important indicators of significant head injury in children.

Abstract
OBJECTIVES The classification of patients with "minor head injury" has relied largely upon the Glasgow Coma Scale (GCS). The GCS however is an insensitive way of defining this heterogeneous subgroup of patients. The aim of the study was to develop an extended GCS 15 category by meta-analysis of previously published case-control studies that have identified symptom risk factors for an abnormal head tomogram. METHODS Eligibility for the study was defined as: (1) Full papers and not abstracts. (2) Case-control or nested case-control studies on GCS 15 patients (adults or adults plus children). Outcome variable being head tomography: normal or abnormal. (3) Documentation of one or more symptom variables such that the odds ratio could be calculated. Five symptom variables were defined for the purpose of the study: headache, nausea, vomiting, blurred vision, and dizziness. RESULTS Three articles fulfilled the criteria for the study. The Mantel-Haenszel test using a pooled estimate was used to calculate the common odds ratio for an abnormal head tomogram for each of the five symptom variables. The odds ratio for the symptom variables was: dizziness 0.594 (95%CI 0.296 to 1.193), blurred vision 0.836 (95%CI 0.369 to 1.893), headache 0.909 (95% CI: 0.601 to 1.375), severe headache 3.211 (95% CI: 2.212 to 4.584), nausea 2.125 (95% CI 1.467 to 3.057), vomiting 4.398 (95% CI 2.790 to 6.932). CONCLUSION The results of this study provide a framework on which GCS category 15 patients can be stratified into four risk categories based upon their symptoms.
