ABSTRACT
BACKGROUND: The modified Gartland classification is the most widely accepted grading method of supracondylar humeral fractures among orthopedic surgeons and is relevant to identifying fractures that may require surgery. OBJECTIVE: To assess the interobserver reliability of the modified Gartland classification among pediatric radiologists, pediatric orthopedic surgeons, and pediatric emergency medicine physicians. MATERIALS AND METHODS: Elbow radiographs for 100 children with supracondylar humeral fractures were retrospectively independently graded by two pediatric radiologists, two pediatric orthopedic surgeons, and two pediatric emergency medicine physicians using the modified Gartland classification. A third grader of the same subspecialty served as a tie-breaker as needed to reach consensus. Readers were blinded to one another and to the medical record. The modified Gartland grade documented in the medical record by the treating orthopedic provider was used as the reference standard. Interobserver agreement was assessed using kappa statistics. RESULTS: There was substantial interobserver agreement (kappa = 0.77 [95% CI, 0.69-0.85]) on consensus fracture grade between the three subspecialties. Similarly, when discriminating between Gartland type I and higher fracture grades, there was substantial interobserver agreement between specialties (kappa = 0.77 [95% CI, 0.66-0.89]). The grade assigned by pediatric radiologists differed from the reference standard on 15 occasions, pediatric emergency medicine differed on 19 occasions, and pediatric orthopedics differed on 9 occasions. CONCLUSION: The modified Gartland classification for supracondylar humeral fractures is reproducible among pediatric emergency medicine physicians, radiologists, and orthopedic surgeons.

Plain Radiography of the spine (PROTS) is utilized in many forms of healthcare including the chiropractic profession; however, the literature reflects conflicting opinions regarding utilization and value. Despite being an essential part of Evidence-Based Practice (EBP), few studies assess Doctors of Chiropractic (DCs) clinical opinions and experience regarding the utilization of (PROTS) in practice. In this study, DCs were surveyed regarding utilization of PROTS in practice. The survey was administered to an estimated 50,000 licensed DCs by email. A total of 4301 surveys were completed, of which 3641 were United States (US) DCs. The Clinician Opinion and Experience on Chiropractic Radiography (COECR) scale was designed to analyze survey responses. This valid and reliable scale demonstrated good internal consistency using confirmatory factor analysis and the Rasch model. Survey responses show that 73.3% of respondents utilize PROTS in practice and 26.7% refer patients out for PROTS. Survey responses show that, among US DCs, 91.9% indicate PROTS has value beyond identification of pathology, 86.7% indicate that PROTS is important regarding biomechanical analysis of the spine, 82.9% indicate that PROTS is vital to practice, 67.4% indicate that PROTS aids in measuring outcomes, 98.6% indicate the opinion that PROTS presents very low to no risk to patients, and 93.0% indicate that sharing clinical findings from PROTS studies with patients is beneficial to clinical outcomes. The results of the study indicated that based on clinical experience, the majority of DCs find PROTS to be vital to practice and valuable beyond the identification of red flags.
ABSTRACT
There is little current literature on the augmented-pressure distal colostogram, the single most important diagnostic study performed in boys with imperforate anus prior to definitive repair. Accurate understanding of the anatomy of the anorectal malformation including an associated fistulous communication between the rectum and the urogenital tract is essential for optimal surgical management. Specifically, the position of the rectal pouch and recto-urinary fistula relative to posterior sagittal structures of the perineum, especially the sacral spine, dictates the operative approach. This pictorial essay is a guide for those who encounter such children with relative infrequency to become more comfortable with the technique. We report how to perform this radiologic exam and the potential pitfalls from our experience of performing the technique in our large pediatric colorectal practice.

OBJECTIVE: To evaluate superb microvascular imaging (SMI) for the detection of high-grade vesicoureteral reflux (VUR). METHODS: We reviewed the patients with urinary tract infection who underwent renal US with SMI and VCUG. The subjects were divided into a VUR group, which included 17 patients (20 kidney units, KU) with high-grade reflux (grade 4 or 5) on VCUG, and a group without VUR including the same numbers of subjects. The direction of urine movement at the distal ureter and the renal pelvis was reviewed on SMI. SMI and VCUG results were compared. RESULTS: Urinary flow "jets" into the bladder and direction of the flow were detectable on all SMI examinations in both groups. In the group with VUR, 20 KUs had grade 4 (n = 11) or grade 5 (n = 9) reflux (bilateral VUR in 3 patients). Among 20 KUs with VUR, 15 (75%) showed a reversed ureteral jet and/or renal pelvic swirl sign on SMI. None of the patients in the group without VUR showed those findings on SMI. CONCLUSION: SMI enables detection of the direction of urinary flow. The presence of a reversed ureteral jet and/or renal pelvic swirl sign correlates with high-grade VUR with 75% accuracy. KEY POINTS: ⢠Superb microvascular imaging is feasible in children with urinary tract infection. ⢠SMI enables detection of the direction of urinary flow. ⢠Presence of reversed flow correlates with high-grade vesicoureteral reflux.

When a female is born and has only a single perineal orifice on the newborn clinical examination, a diagnosis of cloaca type of anorectal malformation is made. Along with associated malformations which may initiate the ordering of radiologic imaging, there are a finite number of radiologic tests that are performed to help in the immediate management of the patient with cloaca. The following discussion will outline the most important radiologic tests and demonstrate examples of images from newborn females with cloaca.

OBJECTIVES: We report our institution's 5-year experience with upper gastrointestinal study with small bowel follow-through (UGI-SBFT) and contrast enema (CE) for the diagnosis of a post-necrotizing enterocolitis (NEC) stricture. We hypothesized that sensitivity and specificity of UGI-SBFT and CE were <85% in diagnosing a post-NEC stricture. METHODS: A retrospective observational cohort study was performed. Included patients were neonates diagnosed as having Bell's modified stage 2 or 3 NEC who had undergone UGI-SBFT and/or CE to evaluate for a stricture. Exploratory laparotomy was used to definitively determine the stricture presence, which was confirmed by pathology. An infant was categorized as having no stricture if no surgical intervention occurred or if no stricture was reported on pathology following surgical resection. RESULTS: A total of 56 patients met inclusion criteria, with 51 UGI-SBFT and 85 CE performed. A total of 25 patients were diagnosed as having a stricture. For small bowel (SB) strictures, CE compared with UGI-SBFT has a higher sensitivity (0.667 vs 0.00) and a similar specificity (0.857 vs 0.833). For SB and/or colonic strictures, CE has a sensitivity of 0.667 and a specificity of 0.951. Strictures were more likely to be found on imaging in symptomatic infants compared with those in asymptomatic infants (28% vs 8%, P = 0.002). CONCLUSIONS: CE should be the initial study in the diagnostic workup for a post-NEC stricture because this test has a higher likelihood of detecting a stricture if it is present. As a result of low sensitivity of UGI-SBFT and/or CE in the diagnosis of a post-NEC stricture, a negative study should not rule out the diagnosis of a stricture in persistently symptomatic patients.

BACKGROUND: The radiologic evaluation of Hirschsprung disease is well described in the literature. However, there is a paucity of literature describing the appearance of the neo-rectum and colon after repair, specifically describing findings in patients with poor functional outcome, which would suggest the need for reoperation. OBJECTIVE: We describe findings on contrast enema and correlate them with surgical findings at reoperation in children with poor functional outcome after primary repair for Hirschsprung disease who suffer from bowel dysfunction that can manifest with either soiling or obstructive symptoms such as enterocolitis. MATERIALS AND METHODS: Children were identified from our colorectal surgery database. At the time of abstract submission, 35 children had contrast enemas prior to reoperation. Additional children continue to present for evaluation. The majority of children included in the study had their primary repair performed elsewhere. The initial procedures included: Duhamel (n = 11), Soave (n = 20) or Swenson (n = 3). One child had undergone a primary Soave repair and subsequently had a Swenson-type reoperation but continued to have a poor outcome. One child's initial surgical repair could not be determined. Images were reviewed by a staff pediatric radiologist and a pediatric radiology fellow. RESULTS: Findings encountered on contrast enema in these children include a distal narrowed segment due to stricture or aganglionic/transitional zone segment (8), dilated/hypomotile distal segment (7), thickened presacral space due to compressing Soave cuff (11), dilated Duhamel pouch (8), active enterocolitis (3) and partially obstructing twist of the pull-through segment (1). CONCLUSION: Multiple anatomical and pathological complications exist that can lead to bowel dysfunction in children after repair of Hirschsprung disease. Little recent literature exists regarding the radiographic findings in children. We had the opportunity to review a substantial series of these children, describe the contrast enema findings in these difficult cases and correlate them with operative findings. Radiologic evaluation is key to assessing such patients; it defines the potential anatomical problem with the pull-through and facilitates surgical planning.
