Examining differential effects of an equity-focused schoolwide positive behavioral interventions and supports approach on teachers' equity in school discipline.

Following a randomized controlled trial that showed effectiveness of an equity-centered positive behavioral interventions and supports (PBIS) professional development intervention on student discipline in elementary schools, we studied the extent to which the intervention had differential effects on individual teachers' use of exclusionary discipline. Using the sample of teachers from the randomized controlled trial (n = 348), we assessed whether (a) changes in teacher use of office discipline referrals over the course of 2 school years and (b) intervention acceptability were moderated by teacher demographic characteristics (e.g., race/ethnicity, experience) or teacher attitudes (e.g., awareness of biases and commitment to equity). Results from multilevel models using two discipline outcomes (i.e., office discipline referrals issued to Black students and equity in office discipline referrals) did not show significant moderation effects for any demographic or attitude variables. Results of intervention acceptability found that teachers with pre-existing commitments to bias reduction found the intervention more acceptable, although means were consistently high across the sample. Findings indicate that the intervention was similarly effective on teacher discipline practices, regardless of teacher demographics or pre-existing attitudes, lending more support to the intervention's promise.

Urine Toxicology Test for Children With Altered Mental Status.

The rate of unintentional ingestion of edible cannabis products in young children is rising rapidly as laws decriminalizing both recreational and medical marijuana in the United States become more widespread.1 Cannabis poisoning in children can lead to a myriad of symptoms, most notably neurologic changes. The abrupt onset and severity of signs and symptoms after ingestion can cause diagnostic uncertainty for practitioners in the emergency department. Here, we present a case series of 5 children, 6 years of age and younger, who initially presented with altered mental status and were ultimately diagnosed with acute δ-9-tetrahydrocannabinol toxicity after cannabis ingestion confirmed by urine toxicology testing. Although urine toxicology testing is not routinely used as a diagnostic tool in pediatrics, the increasing accessibility of edible cannabis products suggests that more widespread urine toxicology testing in children with undifferentiated altered mental status is warranted.

Adolescents with spondylolysis have lower SRS-22 scores than controls and peers with pre-operative idiopathic scoliosis.

PURPOSE: The Scoliosis Research Society Outcomes Questionnaire (SRS-22) is a health-related quality-of-life (HRQL) tool for scoliosis patients. Since no equivalent questionnaire exists for spondylolysis patients, we characterized patient-reported scores in pediatric spondylolysis patients using the SRS-22, and compared these scores to previously published values for age-matched controls and patients with pre-operative adolescent idiopathic scoliosis (AIS). METHODS: A single-institution cross-sectional observational study was performed using SRS-22 data from spondylolysis patients aged 12-18 years. Mean SRS-22 domain scores were compared to the existing literature values for adolescent control and AIS cohorts via unpaired Student t tests (α = 0.05) and against minimal clinically important differences (MCIDs). RESULTS: Thirty-five patients met inclusion criteria. Mean (± SD) spondylolysis patients' scores met the MCID across all domains except Mental Health (α= 0.05). Spondylolysis patient scores for Pain, Function, and Self-Image were significantly lower (p < 0.01) than AIS patients (Pain; 2.99 ± 0.66 vs 4.14 ± 0.79; Function; 3.81 ± 0.61 vs 4.09 ± 0.54; Self-Image; 3.45 ± 0.70 vs 3.80 ± 0.68). CONCLUSION: The adolescent spondylolysis population has clinically significantly lower SRS-22 scores compared to age-matched controls and AIS patients, suggesting that the SRS-22 questionnaire should be given to this population to assess patients' HRQL. Further research is needed to assess the utility of the SRS-22 in measuring treatment effects. LEVEL OF EVIDENCE: III.

A Systematic Review of the Utility of Postoperative Imaging in the Management of Pediatric Supracondylar Humerus Fractures.

BACKGROUND: Recently published studies call into question the clinical utility of postoperative radiographs in the management of pediatric supracondylar humerus (SCH) fractures. This topic has been addressed as part of the American Academy of Orthopaedic Surgeons Appropriate Use Criteria, although recommendations regarding serial radiographs were not included as part of the discussion. The purpose of this systematic review is to summarize the recent literature regarding the utility of postoperative radiographs as part of the management of SCH fractures. METHODS: A systematic review of the literature published between January 1, 2000 and December 31, 2017 was conducted using PubMed/MEDLINE and SCOPUS databases to identify studies relevant to postoperative management of SCH. Eight studies met the inclusion criteria, from which data pooled estimates and an analysis of heterogeneity were calculated. RESULTS: The pooled estimate of changes in fracture management on the basis of postoperative radiographs was 1% (0.98±0.33). Significant interstudy heterogeneity was observed with an I test statistic of 76%. Changes in fracture management included prolonged immobilization following pin removal and return to the operating room. CONCLUSIONS: There is a paucity of articles focusing on the utility or appropriate use of postoperative radiographs in changing management of SCH fractures, one of the most common upper extremity fractures in children. There is a very low rate of change in management on the basis of imaging, and frequently authors commented that the management change could have been prompted without routine serial radiographs. The cumulate findings of these studies suggest routine postoperative radiographs after SCH fractures are infrequently associated with changes in management. Practitioners should consider postoperative protocols with the intention of identifying early postoperative alignment loss or when the complication is suspected to prevent excessive routine radiography in the management of pediatric SCH fractures. LEVEL OF EVIDENCE: Level III-systematic review of level III studies.

Postoperative management factors affect urinary retention following posterior spinal fusion for adolescent idiopathic scoliosis.

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: This study investigates postoperative urinary retention (POUR) following posterior spinal fusion (PSF) for adolescent idiopathic scoliosis (AIS) and the effects of postoperative analgesia and mobility on retention. High opioid use and decreased postoperative mobility are proposed risk factors for retention in adults. There is a paucity of literature on POUR in the adolescent population undergoing surgery for AIS. The impact of pain control and mobility on POUR in these patients is unknown. METHODS: A retrospective cohort study was conducted of adolescents (11-18 years) undergoing elective PSF for AIS at a single institution (2012-2018). POUR was defined as the inability to void > 8 h after catheter removal. Possible risk factors for retention including opioid usage and ambulatory status at the time of catheter removal were assessed on univariate and binomial logistic regression analyses. RESULTS: One hundred and thirty-six patients were included, with 21 (15.4%) experiencing POUR. On the day of catheter removal, 24 patients had not attempted ambulation; these patients had 2.5 times higher rate of POUR than those who were walking (30% vs. 12%, p = 0.04). Patients who developed retention ambulated a mean threefold shorter distance than those without POUR (45 vs. 136 feet, p = 0.04). On binomial logistic regression, decreased ambulation distance was associated with retention (p = 0.038). While opioid use was not significant on univariate analysis, higher opioid use on the day of catheter removal predicted retention on logistic regression (p = 0.001). POUR resolved in all patients (median duration 0.5 days, range 0-12 days). CONCLUSIONS: The development of POUR after PSF for AIS affects one in six patients but resolves quickly. Non-ambulatory patients and patients who received large doses of opioids on the day of catheter removal were more likely to develop POUR. LEVEL OF EVIDENCE: III.

Utility of Follow-up Radiographs After Pin Removal in Supracondylar Humerus Fractures: A Retrospective Cohort Study.

INTRODUCTION: Displaced supracondylar humerus fractures (SCFs) are common pediatric injuries, typically treated by closed reduction and percutaneous pinning (CRPP). Radiographs are obtained at pin removal and subsequently to evaluate fracture healing. We evaluated the utility of radiographs obtained after pin removal in pediatric SCF management. METHODS: A retrospective cohort study of children aged 2 to 11 years with SCF requiring CRPP at a single institution from January 2007 to July 2017 was conducted. Radiographs were taken at pin removal and minimum 3 weeks later. Demographic and treatment data were collected via chart review. Radiographic measures were Baumann and lateral humeral-capitellar angles, anterior humeral line alignment, and number of cortices with callus. The McNemar-Bowker test analyzed anterior humeral line alignment and cortices with callus. The paired t-test analyzed Baumann and lateral humeral-capitellar angles. RESULTS: One hundred patients were included (47 males and 53 females, mean 5.7 years). The mean time to pin removal was 23.8 days, and the median clinical and radiographic follow-up periods were 109.0 and 52.2 days, respectively. Fracture patterns were extension type II (21%), III (73%), IV (1%), flexion (4%), and varus (1%). No patients' fracture management changed in the acute or long-term postoperative period because of findings on post-pin removal (PPR) radiographs. Fewer cortices with callus were seen at pin removal versus PPR (<0.001). At pin removal, no differences were found in the Baumann angle (75.8 ± 5.0 versus 74.6 ± 5.9; P = 0.053), lateral humeral-capitellar angles (30.7 ± 12.5 versus 31.6 ± 1.3; P = 0.165), or anterior humeral line alignment (P = 0.261). DISCUSSION: No patients' fracture management was modified because of findings evident on PPR radiographs. The number of cortices with callus was the only radiographic measure to differ over time, as is anticipated with routine healing. Elbow radiographic alignment measures did not differ in the interval between radiographs. Therefore, PPR radiographs may not provide clinical utility in the absence of other clinical findings. LEVEL OF EVIDENCE: Level III, retrospective comparative study.
