RESUMO
Previous studies have identified more severe acidosis and higher blood urea nitrogen (BUN) as risk factors for cerebral injury during treatment of diabetic ketoacidosis (DKA) in children; however, cerebral injury also can occur before DKA treatment. We found that lower pH and higher BUN levels also were associated with cerebral injury at presentation.

STUDY OBJECTIVE: To measure the effectiveness of a multimodal strategy, including simultaneous implementation of a clinical decision support system, to sustain adherence to a clinical pathway for care of children with minor head trauma treated in general emergency departments (EDs). METHODS: Prospective, type III hybrid effectiveness-implementation cohort study with a nonrandomized stepped-wedge design and monthly repeated site measures. The study population included pediatric minor head trauma encounters from July 2018 to December 2020 at 21 urban and rural general ED sites in an integrated health care system. Sites received the intervention in 1 of 2 steps, with each site providing control and intervention observations. Measures included guideline adherence, the computed tomography (CT) scan rate, and 72-hour readmissions with clinically important traumatic brain injury. Analysis was performed using multilevel hierarchical modeling with random intercepts for the site and physician. RESULTS: During the study, 12,670 pediatric minor head trauma encounters were cared for by 339 clinicians. The implementation of the clinical pathway resulted in higher odds of guideline adherence (adjusted odds ratio 1.12 [95% confidence interval 1.03 to 1.22]) and lower odds of a CT scan (adjusted odds ratio 0.96 [95% confidence interval 0.93 to 0.98]) in intervention versus control months. Absolute risk difference was observed in both guideline adherence (site median: +2.3% improvement) and the CT scan rate (site median: -6.6% reduction). No 72-hour readmissions with confirmed clinically important traumatic brain injury were identified. CONCLUSION: Implementation of a minor head trauma clinical pathway using a multimodal approach, including a clinical decision support system, led to sustained improvements in adherence and a modest, yet safe, reduction in CT scans among generally low-risk patients in diverse general EDs.

BACKGROUND: Diabetic ketoacidosis in children may cause brain injuries ranging from mild to severe. Whether intravenous fluids contribute to these injuries has been debated for decades. METHODS: We conducted a 13-center, randomized, controlled trial that examined the effects of the rate of administration and the sodium chloride content of intravenous fluids on neurologic outcomes in children with diabetic ketoacidosis. Children were randomly assigned to one of four treatment groups in a 2-by-2 factorial design (0.9% or 0.45% sodium chloride content and rapid or slow rate of administration). The primary outcome was a decline in mental status (two consecutive Glasgow Coma Scale scores of <14, on a scale ranging from 3 to 15, with lower scores indicating worse mental status) during treatment for diabetic ketoacidosis. Secondary outcomes included clinically apparent brain injury during treatment for diabetic ketoacidosis, short-term memory during treatment for diabetic ketoacidosis, and memory and IQ 2 to 6 months after recovery from diabetic ketoacidosis. RESULTS: A total of 1389 episodes of diabetic ketoacidosis were reported in 1255 children. The Glasgow Coma Scale score declined to less than 14 in 48 episodes (3.5%), and clinically apparent brain injury occurred in 12 episodes (0.9%). No significant differences among the treatment groups were observed with respect to the percentage of episodes in which the Glasgow Coma Scale score declined to below 14, the magnitude of decline in the Glasgow Coma Scale score, or the duration of time in which the Glasgow Coma Scale score was less than 14; with respect to the results of the tests of short-term memory; or with respect to the incidence of clinically apparent brain injury during treatment for diabetic ketoacidosis. Memory and IQ scores obtained after the children's recovery from diabetic ketoacidosis also did not differ significantly among the groups. Serious adverse events other than altered mental status were rare and occurred with similar frequency in all treatment groups. CONCLUSIONS: Neither the rate of administration nor the sodium chloride content of intravenous fluids significantly influenced neurologic outcomes in children with diabetic ketoacidosis.

OBJECTIVES: To characterize hemodynamic alterations occurring during diabetic ketoacidosis (DKA) in a large cohort of children and to identify clinical and biochemical factors associated with hypertension. STUDY DESIGN: This was a planned secondary analysis of data from the Pediatric Emergency Care Applied Research Network Fluid Therapies Under Investigation in DKA Study, a randomized clinical trial of fluid resuscitation protocols for children in DKA. Hemodynamic data (heart rate, blood pressure) from children with DKA were assessed in comparison with normal values for age and sex. Multivariable statistical modeling was used to explore clinical and laboratory predictors of hypertension. RESULTS: Among 1258 DKA episodes, hypertension was documented at presentation in 154 (12.2%) and developed during DKA treatment in an additional 196 (15.6%), resulting in a total of 350 DKA episodes (27.8%) in which hypertension occurred at some time. Factors associated with hypertension at presentation included more severe acidosis, (lower pH and lower pCO2), and stage 2 or 3 acute kidney injury. More severe acidosis and lower Glasgow Coma Scale scores were associated with hypertension occurring at any time during DKA treatment. CONCLUSIONS: Despite dehydration, hypertension occurs in a substantial number of children with DKA. Factors associated with hypertension include greater severity of acidosis, lower pCO2, and lower Glasgow Coma Scale scores during DKA treatment, suggesting that hypertension might be centrally mediated.

OBJECTIVES: We evaluated the association between the emergency department (ED) triage chief complaint and rate of missed appendicitis in children. METHODS: We performed a retrospective chart review of patients who presented to a pediatric ED and were diagnosed with appendicitis over 5 years (July 1, 2009 to June 30, 2014). We reviewed the medical record for any additional ED visits in the 7 days preceding the diagnosis of appendicitis. Triage chief complaints were classified as "suggestive of appendicitis" (abdominal pain, right lower quadrant pain, or rule out appendicitis) or "nonspecific" (fever, vomiting, dehydration, etc). We evaluated the association between triage chief complaint and missed diagnosis of appendicitis. RESULTS: We reviewed 1680 patients with appendicitis. In 67 (4%) cases, patients had at least 1 additional ED visit during the week preceding the diagnosis of appendicitis. When comparing those diagnosed with appendicitis at their initial ED visit to those diagnosed after multiple visits, we found no difference in age (9.9 vs 10.1 years, P = 0.665), sex (55.7% vs 49.3% male, P = 0.291), white blood cell count (14.4 vs 12.3 × 103/L, P = 0.115), or presence of fever (19.9% vs 19.4%, P = 0.920). Of patients with a triage chief complaint that was suggestive of appendicitis, 3.8% were missed on their initial ED visit versus 8.8% of those with a nonspecific triage chief complaint (odds ratio, 2.46; 95% confidence interval, 1.1-5.6). CONCLUSIONS: A triage chief complaint less suggestive of appendicitis was associated with a higher rate of missed appendicitis in a pediatric ED. Our findings further confirm the potential impact of anchoring bias by a triage chief complaint when attempting to diagnose appendicitis.

BACKGROUND: Pain management guidelines in the emergency department (ED) may reduce time to analgesia administration (TTA). Intranasal fentanyl (INF) is a safe and effective alternative to intravenous opiates. The effect of an ED pain management guideline providing standing orders for nurse-initiated administration of intranasal fentanyl (INF) is not known. The objective of this study was to determine the impact of a pediatric ED triage-based pain protocol utilizing intranasal fentanyl (INF) on time to analgesia administration (TTA) and patient and parent satisfaction. METHODS: This was a prospective study of patients 3-17â¯years with an isolated orthopedic injury presenting to a pediatric ED before and after instituting a triage-based pain guideline allowing for administration of INF by triage nurses. Our primary outcome was median TTA and secondary outcomes included the proportion of patients who received INF for pain, had unnecessary IV placement, and patient and parent satisfaction. RESULTS: We enrolled 132 patients; 72 pre-guideline, 60 post-guideline. Demographics were similar between groups. Median TTA was not different between groups (34.5â¯min vs. 33â¯min, pâ¯=â¯.7). Utilization of INF increased from 41% pre-guideline to 60% post-guideline (pâ¯=â¯.01) and unnecessary IV placement decreased from 24% to 0% (pâ¯=â¯.002). Patients and parents preferred the IN route for analgesia administration. CONCLUSION: A triage-based pain protocol utilizing INF did not reduce TTA, but did result in increased INF use, decreased unnecessary IV placement, and was preferred by patients and parents to IV medication. INF is a viable analgesia alternative for children with isolated extremity injuries.

STUDY OBJECTIVE: We describe presentations and outcomes of children with basilar skull fractures in the emergency department (ED) after blunt head trauma. METHODS: This was a secondary analysis of an observational cohort of children with blunt head trauma. Basilar skull fracture was defined as physical examination signs of basilar skull fracture without basilar skull fracture on computed tomography (CT), or basilar skull fracture on CT regardless of physical examination signs of basilar skull fracture. Other definitions included isolated basilar skull fracture (physical examination signs of basilar skull fracture or basilar skull fracture on CT with no other intracranial injuries on CT) and acute adverse outcomes (death, neurosurgery, intubation for >24 hours, and hospitalization for ≥2 nights with intracranial injury on CT). RESULTS: Of 42,958 patients, 558 (1.3%) had physical examination signs of basilar skull fracture, basilar skull fractures on CT, or both. Of the 525 (94.1%) CT-imaged patients, 162 (30.9%) had basilar skull fracture on CT alone, and 104 (19.8%) had both physical examination signs of basilar skull fracture and basilar skull fracture on CT; 269 patients (51.2%) had intracranial injuries other than basilar skull fracture on CT. Of the 363 (91.7%) CT-imaged patients with physical examination signs of basilar skull fracture, 104 (28.7%) had basilar skull fracture on CT. Of 266 patients with basilar skull fracture on CT, 104 (39.1%) also had physical examination signs of basilar skull fracture. Of the 256 CT-imaged patients who had isolated basilar skull fracture, none had acute adverse outcomes (0%; 95% confidence interval 0% to 1.4%), including none (0%; 95% confidence interval 0% to 6.1%) of 59 with isolated basilar skull fractures on CT. CONCLUSION: Approximately 1% of children with blunt head trauma have physical examination signs of basilar skull fracture or basilar skull fracture on CT. The latter increases the risk of acute adverse outcomes more than physical examination signs of basilar skull fracture. A CT scan is needed to adequately stratify the risk of acute adverse outcomes for these children. Children with isolated basilar skull fractures are at low risk for acute adverse outcomes and, if neurologically normal after CT and observation, are candidates for ED discharge.

OBJECTIVE: The lateral and sitting positions are those most widely used to perform lumbar puncture (LP) in infants. This study sought to compare LP success rates by position. Secondary outcomes were successful LP on the first attempt and rates of procedural complications. METHODS: Infants aged 1 to 90 days undergoing LP in our pediatric emergency department between June 1, 2012 and October 31, 2013 were randomized to 1 position or the other. Successful LP was defined as collection of cerebrospinal fluid with a red blood cell count of less than 10,000 cells/mm on either of the first 2 attempts. Electronic medical records were reviewed for patient information, cerebrospinal fluid results, and procedural complications. Providers completed a questionnaire detailing their previous LP experience and technique. Primary results were analyzed using the intention-to-treat principle. RESULTS: We enrolled 168 infants. Of 167 with data eligible for analysis, 82 (49%) were randomized to the lateral position. There was no statistically significant difference in LP success rate between the lateral (77%, 63/82) and sitting (72%, 61/85) positions (difference, 5.1%; 95% confidence interval, -8.2%-18.3%). There were no significant differences in success on the first LP attempt or the rates of procedural complications. CONCLUSIONS: Among infants 1 to 90 days of age, this study found no difference in LP success between the lateral and sitting positions.

The use of computed tomography (CT) in the emergency department (ED) evaluation of pediatric patients for suspected appendicitis can be safely reduced. However, published examples of reduced CT use also report increased MRI utilization, ED length of stay, hospitalization rates, and in-ED surgical consultation. In addition, previous studies recommended follow-up for undifferentiated abdominal pain, yet none with pediatric surgeons. Therefore, we implemented a diagnostic algorithm that includes an option for next-day surgery clinic follow-up in cases where uncertainty remains after appendix ultrasound (US) to reduce CT utilization without increasing hospital-based resources. Methods: We implemented a diagnostic algorithm in January 2014. We retrospectively identified 4,577 patients who underwent an evaluation for suspected appendicitis from January 2012 to September 2015. CT utilization was compared before and after implementation using Statistical Process Control. In addition, we evaluated secondary outcomes, including US utilization, hospital admission, surgery clinic follow-up, ED surgery consultation, ED return visits within 7 days, and ED length of stay. Results: Following the implementation of the algorithm, CT utilization decreased significantly from 13.8% to 6%. Forty-eight patients were evaluated the next day in the optional pediatric surgery clinic for 21 months after implementation. There was no significant change in US utilization, hospital admission, ED surgery consultation, ED return visits within 7 days, or ED length of stay. Conclusion: We achieved decreased CT utilization without an increase in the utilization of other hospital-based resources after implementing a pediatric appendicitis evaluation algorithm that includes the option for next-day pediatric surgery clinic follow-up.
RESUMO
OBJECTIVES: Investigating empirical relationships among laboratory measures in children with diabetic ketoacidosis (DKA) can provide insights into physiological alterations occurring during DKA. We determined whether alterations in laboratory measures during DKA conform to theoretical predictions. METHODS: We used Pearson correlation statistics and linear regression to investigate correlations between blood glucose, electrolytes, pH and PCO2 at emergency department presentation in 1,681 pediatric DKA episodes. Among children with repeat DKA episodes, we also assessed correlations between laboratory measures at the first vs. second episode. RESULTS: pH and bicarbonate levels were strongly correlated (r=0.64), however, pH and PCO2 were only loosely correlated (r=0.17). Glucose levels were correlated with indicators of dehydration and kidney function (blood urea nitrogen (BUN), r=0.44; creatinine, r=0.42; glucose-corrected sodium, r=0.32). Among children with repeat DKA episodes, PCO2 levels tended to be similar at the first vs. second episode (r=0.34), although pH levels were only loosely correlated (r=0.19). CONCLUSIONS: Elevated glucose levels at DKA presentation largely reflect alterations in glomerular filtration rate. pH and PCO2 are weakly correlated suggesting that respiratory responses to acidosis vary among individuals and may be influenced by pulmonary and central nervous system effects of DKA.

INTRODUCTION: Young children with type 1 diabetes (T1D) may be at particularly high risk of cognitive decline following diabetic ketoacidosis (DKA). However, studies of cognitive functioning in T1D typically examine school-age children. The goal of this study was to examine whether a single experience of DKA is associated with lower cognitive functioning in young children. We found that recently diagnosed 3- to 5-year-olds who experienced one DKA episode, regardless of its severity, exhibited lower IQ scores than those with no DKA exposure. METHODS: We prospectively enrolled 46 3- to 5-year-old children, who presented with DKA at the onset of T1D, in a randomized multi-site clinical trial evaluating intravenous fluid protocols for DKA treatment. DKA was moderate/severe in 22 children and mild in 24 children. Neurocognitive function was assessed once 2-6 months after the DKA episode. A comparison group of 27 children with T1D, but no DKA exposure, was also assessed. Patient groups were matched for age and T1D duration at the time of neurocognitive testing. RESULTS: Children who experienced DKA, regardless of its severity, exhibited significantly lower IQ scores than children who did not experience DKA, F(2, 70) = 6.26, p = .003, partial η2 = .15. This effect persisted after accounting for socioeconomic status and ethnicity. CONCLUSIONS: A single DKA episode is associated with lower IQ scores soon after exposure to DKA in young children.

BACKGROUND AND OBJECTIVES: The Pediatric Emergency Care Applied Research Network Fluid Therapies Under Investigation in Diabetic Ketoacidosis (DKA) (FLUID) Trial found that rapid fluid infusion does not increase the risk of cerebral injury. Concern persists, however, whether fluid rates should be adjusted for overweight or obese patients. We used the FLUID Trial database to evaluate associations between fluid infusion rate and outcomes in these patients. METHODS: We compared children and youth who were overweight, obese, or normal weight, in regard to protocol adherence, mental status changes, time to DKA resolution, and electrolyte abnormalities. We investigated associations between outcomes and the amount of fluid received in these groups. RESULTS: Obese children and youth were more likely to receive fluids at rates slower than dictated by protocol. Overweight and obese children and youth in the fast fluid arms, who received fluids per the study protocol based on their measured weight, had similar rates of mental status changes or clinically apparent cerebral injury as those with normal weights. Risk of hypophosphatemia was increased in those receiving larger initial bolus volumes and reduced in those receiving higher rehydration rates. No other metabolic outcomes were associated with rehydration. CONCLUSIONS: Protocol adherence data in the FLUID Trial suggest that physicians are uncomfortable using weight-based fluid calculations for overweight or obese children. However, higher rates of fluid infusion were not associated with increased risk of mental status changes or cerebral injury, suggesting that physicians should not limit fluid resuscitation in obese children and youth with DKA.

BACKGROUND: Surges in patient volumes compromise emergency departments' (EDs') ability to deliver care, as shown by the recent H1N1 influenza (flu) epidemic. Media reports are important in informing the public about health threats, but the effects of media-induced anxiety on ED volumes are unclear. OBJECTIVE: The aim of this study is to examine the effect of widespread public concern about flu on ED use. METHODS: We reviewed ED data from an integrated health system operating 18 hospital EDs. We compared ED visits during three 1-week periods: (a) a period of heightened public concern regarding flu before the disease was present ("Fear Week"), (b) a subsequent period of active disease ("Flu Week"), and (c) a week before widespread concern ("Control Week"). Fear Week was identified from an analysis of statewide Google electronic searches for "swine flu" and from media announcements about flu. Flu Week was identified from statewide epidemiological data. RESULTS: Data were reviewed from 22 608 visits during the study periods. Fear Week (n = 7712) and Flu Week (n = 7687) were compared to Control Week (n = 7209). Fear Week showed a 7.0% increase in visits (95% confidence interval, 6-8). Pediatric visits increased by 19.7%, whereas adult visits increased by 1%. Flu Week showed an increase over Control Week of 6.6% (95% confidence interval, 6-7). Pediatric visits increased by 10.6%, whereas adult visits increased by 4.8%. CONCLUSION: At a time of heightened public concern regarding flu but little disease prevalence, EDs experienced substantial increases in patient volumes. These increases were significant and comparable to the increases experienced during the subsequent epidemic of actual disease.

STUDY OBJECTIVE: Children evaluated in the emergency department (ED) with minor blunt head trauma, defined by initial Glasgow Coma Scale (GCS) scores of 14 or 15, are frequently hospitalized despite normal cranial computed tomography (CT) scan results. We seek to identify the frequency of neurologic complications in children with minor blunt head trauma and normal ED CT scan results. METHODS: We conducted a prospective, multicenter observational cohort study of children younger than 18 years with blunt head trauma (including isolated head or multisystem trauma) at 25 centers between 2004 and 2006. In this substudy, we analyzed individuals with initial GCS scores of 14 or 15 who had normal cranial CT scan results during ED evaluation. An abnormal imaging study result was defined by any intracranial hemorrhage, cerebral edema, pneumocephalus, or any skull fracture. Patients with normal CT scan results who were hospitalized were followed to determine neurologic outcomes; those discharged to home from the ED received telephone/mail follow-up to assess for subsequent neuroimaging, neurologic complications, or neurosurgical intervention. RESULTS: Children (13,543) with GCS scores of 14 or 15 and normal ED CT scan results were enrolled, including 12,584 (93%) with GCS scores of 15 and 959 (7%) with GCS scores of 14. Of 13,543 patients, 2,485 (18%) were hospitalized, including 2,107 of 12,584 (17%) with GCS scores of 15 and 378 of 959 (39%) with GCS scores of 14. Of the 11,058 patients discharged home from the ED, successful telephone/mail follow-up was completed for 8,756 (79%), and medical record, continuous quality improvement, and morgue review was performed for the remaining patients. One hundred ninety-seven (2%) children received subsequent CT or magnetic resonance imaging (MRI); 5 (0.05%) had abnormal CT/MRI scan results and none (0%; 95% confidence interval [CI] 0% to 0.03%) received a neurosurgical intervention. Of the 2,485 hospitalized patients, 137 (6%) received subsequent CT or MRI; 16 (0.6%) had abnormal CT/MRI scan results and none (0%; 95% CI 0% to 0.2%) received a neurosurgical intervention. The negative predictive value for neurosurgical intervention for a child with an initial GCS score of 14 or 15 and a normal CT scan result was 100% (95% CI 99.97% to 100%). CONCLUSION: Children with blunt head trauma and initial ED GCS scores of 14 or 15 and normal cranial CT scan results are at very low risk for subsequent traumatic findings on neuroimaging and extremely low risk of needing neurosurgical intervention. Hospitalization of children with minor head trauma after normal CT scan results for neurologic observation is generally unnecessary.

INTRODUCTION: Acquiring parental consent is critical to pediatric clinical research, especially in interventional trials. In this study we investigated demographic, clinical, and environmental factors associated with likelihood of parental permission for enrollment in a study of therapies for diabetic ketoacidosis (DKA) in children. METHODS: We analyzed data from patients and parents who were approached for enrollment in the Pediatric Emergency Care Applied Research Network (PECARN) Fluid Therapies Under Investigation in DKA (FLUID) trial at one major participating center. We determined the influence of various factors on patient enrollment, including gender, age, distance from home to hospital, insurance status, known vs new onset of diabetes, glycemic control (hemoglobin A1c), DKA severity, gender of the enroller, experience of the enroller, and time of enrollment. Patients whose parents consented to participate were compared to those who declined participation using bivariable and multivariable analyses controlling for the enroller. RESULTS: A total of 250 patient/parent dyads were approached; 177 (71%) agreed to participate, and 73 (29%) declined. Parents of patients with previous episodes of DKA agreed to enroll more frequently than those with a first DKA episode (94.3% for patients with 1-2 previous DKA episodes, 92.3% for > 2 previous episodes, vs 64.9% for new onset diabetes and 63.2% previously diagnosed but no previous DKA). Participation was also more likely with more experienced enrollers (odds ratio [95% confidence interval] of participation for an enroller with more than two years' experience vs less than two years: 2.46 [1.53, 3.97]). After adjusting for demographic and clinical factors, significant associations between participation and both DKA history and enroller experience remained. Patient age, gender, distance of home from hospital, glycemic control, insurance status, and measures of DKA severity were not associated with likelihood of participation. CONCLUSION: Familiarity with the disease process (previously diagnosed diabetes and previous experience with DKA) and experience of the enroller favorably influenced the likelihood of parental permission for enrollment in a study of DKA in children.

OBJECTIVES: Diabetic ketoacidosis (DKA) is typically characterized by low or low-normal serum sodium concentrations, which rise as hyperglycemia resolves. In retrospective studies, researchers found associations between declines in sodium concentrations during DKA and cerebral injury. We prospectively investigated determinants of sodium concentration changes and associations with mental status alterations during DKA. METHODS: Using data from the Pediatric Emergency Care Applied Research Network Fluid Therapies Under Investigation in Diabetic Ketoacidosis Trial, we compared children who had declines in glucose-corrected sodium concentrations with those who had rising or stable concentrations. Children were randomly assigned to 1 of 4 intravenous fluid protocols that differed in infusion rate and sodium content. Data from the first 4, 8, and 12 hours of treatment were analyzed for 1251, 1086, and 877 episodes, respectively. RESULTS: In multivariable analyses, declines in glucose-corrected sodium concentrations were associated with higher sodium and chloride concentrations at presentation and with previously diagnosed diabetes. Treatment with 0.45% (vs 0.9%) sodium chloride fluids was also associated with declines in sodium concentration; however, higher rates of fluid infusion were associated with declines in sodium concentration only at 12 hours. Frequencies of abnormal Glasgow Coma Scale scores and clinical diagnoses of cerebral injury were similar in patients with and without declines in glucose-corrected sodium concentrations. CONCLUSIONS: Changes in glucose-corrected sodium concentrations during DKA treatment are influenced by the balance of free-water loss versus sodium loss at presentation and the sodium content of intravenous fluids. Declines in glucose-corrected sodium concentrations are not associated with mental status changes during treatment.

BACKGROUND: CT imaging of head-injured children has risks of radiation-induced malignancy. Our aim was to identify children at very low risk of clinically-important traumatic brain injuries (ciTBI) for whom CT might be unnecessary. METHODS: We enrolled patients younger than 18 years presenting within 24 h of head trauma with Glasgow Coma Scale scores of 14-15 in 25 North American emergency departments. We derived and validated age-specific prediction rules for ciTBI (death from traumatic brain injury, neurosurgery, intubation >24 h, or hospital admission >or=2 nights). FINDINGS: We enrolled and analysed 42 412 children (derivation and validation populations: 8502 and 2216 younger than 2 years, and 25 283 and 6411 aged 2 years and older). We obtained CT scans on 14 969 (35.3%); ciTBIs occurred in 376 (0.9%), and 60 (0.1%) underwent neurosurgery. In the validation population, the prediction rule for children younger than 2 years (normal mental status, no scalp haematoma except frontal, no loss of consciousness or loss of consciousness for less than 5 s, non-severe injury mechanism, no palpable skull fracture, and acting normally according to the parents) had a negative predictive value for ciTBI of 1176/1176 (100.0%, 95% CI 99.7-100 0) and sensitivity of 25/25 (100%, 86.3-100.0). 167 (24.1%) of 694 CT-imaged patients younger than 2 years were in this low-risk group. The prediction rule for children aged 2 years and older (normal mental status, no loss of consciousness, no vomiting, non-severe injury mechanism, no signs of basilar skull fracture, and no severe headache) had a negative predictive value of 3798/3800 (99.95%, 99.81-99.99) and sensitivity of 61/63 (96.8%, 89.0-99.6). 446 (20.1%) of 2223 CT-imaged patients aged 2 years and older were in this low-risk group. Neither rule missed neurosurgery in validation populations. INTERPRETATION: These validated prediction rules identified children at very low risk of ciTBIs for whom CT can routinely be obviated.

This is a case of a 3-year-old boy with a sunflower-seed rectal bezoar who presented to our emergency department with fever, abdominal pain, leukocytosis, vomiting, and an examination concerning for appendicitis. A failed diagnostic imaging attempt ultimately led to the diagnosis. Children with rectal bezoars typically present with diarrhea, rectal pain, and tenesmus. Our patient presented atypically and developed significant colitis secondary to the bezoar. We discuss bezoars and the uncommon rectal seed bezoar. This case illustrates an atypical complication (colitis) of an unusual condition (rectal bezoar) mimicking a relatively common illness (appendicitis).
