Gastric-Type Enteric Duplication Cyst Communicating with an Accessory Pancreatic Duct.

Enteric duplication cysts are rare congenital anomalies defined by the location along the gastrointestinal tract from which they communicate as well as the epithelial lining they contain. Enteric duplication cysts in communication with the pancreas are an even rarer subset that are often difficult to diagnose due to nonspecific presenting symptoms. In a pediatric patient with a history of recurrent pancreatitis episodes, a pancreatic duplication should be on the differential. High clinical suspicion and specific imaging characteristics can aid in the diagnosis. The management of pancreatic duplication cysts requires surgical excision or drainage procedures to alleviate symptoms and prevent associated complications such as recurrent pancreatitis, bleeding, bowel obstruction, or malignancy. Here we present a case of a gastric duplication cyst in communication with an accessory pancreatic lobe with special focus on the preoperative workup, intraoperative findings, and histopathologic examination.

Pediatric hemodialysis access.

Pediatric hemodialysis access is a demanding field. Procedures are infrequent, technically challenging, and associated with high complication and failure rates. Each procedure affects subsequent access and transplants sites. The choice is made easier and outcomes improved when access decisions are made by a multidisciplinary, pediatric, hemodialysis access team. This manuscript reviews the current literature and offers technical suggestions to improve outcomes.

Meconium-stained amniotic fluid as a predictor of poor outcomes in gastroschisis.

OBJECTIVE: The aim of this study was to determine if meconium-stained amniotic fluid (MSAF) was associated with neonatal outcomes in gastroschisis. STUDY DESIGN: A retrospective chart review of gastroschisis patients from 2000 to 2014 at a single, tertiary institution was performed. Statistical analysis was performed with Fisher exact test, Welch's t-test, logistic regression and/or linear regression with significance at p < 0.05. RESULTS: Sixty-four of 135 (47.4%) gastroschisis patients had MSAF. On univariate analysis, patients with MSAF were more likely to require staged closure (30 (46.9%) vs. 18(25.4%), p = 0.012), had more ventilator days (8.9 ±â€¯11.1 vs. 5.3 ±â€¯6.3, p = 0.021) and longer times to commence enteral feeds (24.9 ±â€¯21.7 vs. 18.5 ±â€¯14.5, p = 0.045). However, multi-variate regression analysis controlling for the type of closure, showed that delayed closure, but not MSAF, was associated with worse outcomes. CONCLUSIONS: In gastroschisis patients, MSAF is associated with delayed closure but is not associated with outcomes independent of closure type. This association may be because of the matting of the bowel or increased intestinal damage. The MSAF status will aid in setting expectations for parents during their initial NICU stay and further investigation is warranted. TYPE OF STUDY: Clinical Research Paper Level of evidence: III.

Intestinal alkaline phosphatase deficiency leads to dysbiosis and bacterial translocation in the newborn intestine.

BACKGROUND: Intestinal alkaline phosphatase (IAP) has been shown to help maintain intestinal homeostasis. Decreased expression of IAP has been linked with pediatric intestinal diseases associated with bacterial overgrowth and subsequent inflammation. We hypothesize that the absence of IAP leads to dysbiosis, with increased inflammation and permeability of the newborn intestine. METHODS: Sprague-Dawley heterozygote IAP cross-matches were bred. Pups were dam fed ad lib and euthanized at weaning. The microbiotas of terminal ileum (TI) and colon was determined by quantitative real-time polymerase chain reaction (qRT-PCR) of subphylum-specific bacterial 16S ribosomal RNA. RT-PCR was performed on TI for inflammatory cytokines. Intestinal permeability was quantified by fluorescein isothiocyanate-dextran permeability and bacterial translocation by qRT-PCR for bacterial 16S ribosomal RNA in mesenteric lymph nodes. Statistical analysis was done by chi-square analysis. RESULTS: All three genotypes had similar concentrations of bacteria in the TI and colon. However, IAP knockout (IAP-KO) had significantly decreased diversity of bacterial species in their colonic stool compared with heterozygous and wild-type (WT). IAP-KO pups had a nonstatistically significant 3.9-fold increased inducible nitric oxide synthase messenger RNA expression compared with WT (IAP-KO, 3.92 ± 1.36; WT, 1.0 ± 0.27; P = 0.03). IAP-KO also had significantly increased bacterial translocation to mesenteric lymph nodes occurred in IAP-KO (IAP-KO, 7625 RFU/g ± 3469; WT, 4957 RFU/g ± 1552; P = 0.04). Furthermore, IAP-KO had increased permeability (IAP-KO, 0.297 mg/mL ± 0.2; WT, 0.189 mg/mL ± 0.15 P = 0.07), but was not statistically significant. CONCLUSIONS: Deficiency of IAP in the newborn intestine is associated with dysbiosis and increased inflammation, permeability, and bacterial translocation.

The significance of organ prolapse in gastroschisis.

PURPOSE: The aim of this study was to evaluate the incidence and importance of organ prolapse (stomach, bladder, reproductive organs) in gastroschisis. METHODS: This is a retrospective review of gastroschisis patients from 2000 to 2014 at a single tertiary institution. Statistical analysis was performed using a chi-square test, Student's t test, log-rank test, or Cox regression analysis models. All tests were conducted as two-tailed tests, and p-values <0.05 were considered statistically significant. RESULTS: One hundred seventy-one gastroschisis patients were identified. Sixty-nine (40.6%) had at least one prolapsed organ besides bowel. The most commonly prolapsed organs were stomach (n=45, 26.3%), reproductive organs (n=34, 19.9%), and bladder (n=15, 8.8%). Patients with prolapsed organs were more likely to have simple gastroschisis with significant decreases in the rate of atresia and necrosis/perforation. They progressed to earlier enteral feeds, discontinuation of parenteral nutrition, and discharge. Likewise, these patients were less likely to have complications such as central line infections, sepsis, and short gut syndrome. CONCLUSIONS: Gastroschisis is typically described as isolated bowel herniation, but a large portion have prolapse of other organs. Prolapsed organs are associated with simple gastroschisis, and improved outcomes most likely due to a larger fascial defect. This may be useful for prenatal and postnatal counseling of families.

Magnetic Compression Stricturoplasty For Treatment of Refractory Esophageal Strictures in Children: Technique and Lessons Learned.

INTRODUCTION: Esophageal stricture is the most common complication following repair of esophageal atresia (EA). In general, these strictures are successfully managed using endoscopic techniques including bougie and balloon dilation, stenting, and chemotherapeutic agent application. If these techniques are unsuccessful, patients require segmental esophageal resection and reanastomosis or esophageal replacement. Magnetic compression anastomosis has been described in children. Herein we report our experience with magnetic compression stricturoplasty to treat refractory strictures after EA repair. METHODS: We reviewed our experience using magnets to treat refractory strictures in 2 patients. Both patients failed multiple standard interventions. Because of near complete esophageal obstruction, both patients were candidates for esophageal replacement or segmental resection/anastamosis. In both patients, we applied neodymium-iron-boron magnets using fluoroscopic and endoscopic guidance. RESULTS: The magnets were successfully positioned in both cases. Magnets were left in place for 7 and 10 days allowing for gradual compression stricturoplasty/anastamosis. Upon removal of the magnets, recanalization was visualized endoscopically and self-expanding stents were placed. There were no leaks or significant early complications. By 31 months post-magnetic stricturoplasty, both patients achieved durable esophageal patency without dysphagia. CONCLUSION: Magnetic stricturoplasty was successful at establishing early patency of the esophagus in 2 patients with recalcitrant EA strictures. Fundamental knowledge of magnetism was critical in configuring magnet arrays for surgery. In both cases, early follow-up is promising. Further follow-up will define the long-term success of this technique.

Pediatric Granular Cell Tumor of the Breast: A Case Report and Review of the Literature.

Objective. Granular cell tumors arise from neurogenic mesenchymal stem cells and can occur anywhere throughout the body. They rarely present as breast masses and should be included in the differential diagnosis of pediatric breast neoplasms. We report a rare presentation of a pediatric breast granular cell tumor and a review of the literature. Participant. A 15-year-old female presented with an enlarging breast mass. She underwent ultrasound imaging and excisional biopsy, which revealed a granular cell tumor. Granular cell tumors of the breast are difficult to diagnose using ultrasound and mammography due to numerous similarities to other breast masses. Histopathologic staining best differentiates breast granular cell tumors from other breast masses with their positive staining for S100, CD68, and neurospecific enolase. Conclusion. Although rare, granular cell tumors of the breast should be considered as a possible diagnosis for pediatric breast masses to allow for proper management and follow-up for these patients. Although rare, these tumors do have malignant potential necessitating a correct and timely diagnosis.

Intestinal alkaline phosphatase to treat necrotizing enterocolitis.

BACKGROUND: Intestinal alkaline phosphatase (IAP) activity is decreased in necrotizing enterocolitis (NEC), and IAP supplementation prevents NEC development. It is not known if IAP given after NEC onset can reverse the course of the disease. We hypothesized that enteral IAP given after NEC induction would not reverse intestinal injury. MATERIALS AND METHODS: NEC was induced in Sprague-Dawley pups by delivery preterm followed by formula feedings with lipopolysaccharide (LPS) and hypoxia exposure and continued up to 4 d. IAP was added to feeds on day 2 until being sacrificed on day 4. NEC severity was scored based on hematoxylin and eosin-stained terminal ileum sections, and AP activity was measured using a colorimetric assay. IAP and interleukin-6 expression were measured using real time polymerase chain reaction. RESULTS: NEC pups' alkaline phosphatase (AP) activity was decreased to 0.18 U/mg compared with controls of 0.57 U/mg (P < 0.01). Discontinuation of LPS and hypoxia after 2 d increased AP activity to 0.36 U/mg (P < 0.01). IAP supplementation in matched groups did not impact total AP activity or expression. Discontinuing LPS and hypoxia after NEC onset improved intestinal injury scores to 1.14 compared with continued stressors, score 2.25 (P < 0.01). IAP supplementation decreased interleukin-6 expression two-fold (P < 0.05), though did not reverse NEC intestinal damage (P = 0.5). CONCLUSIONS: This is the first work to demonstrate that removing the source of NEC improves intestinal damage and increases AP activity. When used as a rescue treatment, IAP decreased intestinal inflammation though did not impact injury making it likely that IAP is best used preventatively to those neonates at risk.

Negative pressure dressing assisted healing in pediatric burn patients.

BACKGROUND/PURPOSE: Pediatric burn patients traditionally require multiple dressing changes and significant amounts of narcotics. Negative pressure dressings (NPDs) have emerged as an effective wound therapy that may represent an alternative primary dressing for these patients. METHODS: This is a single institution, retrospective study of pediatric burn patients treated with NPDs over a defined 2 year period. Twenty-two patients were identified and their charts reviewed for age, sex, mode of injury, location of injury, degree of burn, length of stay, length of dressing required, number of dressing changes, and narcotic use between dressing changes. RESULTS: The average patient was 3.5 years old (range of 8 months to 10 years old) with partial thickness burns involving 8.5% (range 3-18%) body surface area. The average treatment regimen was 3.5 dressing changes more than 6.6 days, with a mean hospital stay of 9.6 days. The average child received 9.4 total doses of delivered narcotics during their inpatient care. DISCUSSION: The use of NPD in pediatric burn patients does require sedation and narcotics which limits its usefulness in the general pediatric burn population. Yet, they adhere well and stay in place even on active children, they capture and quantify fluid losses, they only require changes every 2-4 days and promote the adherence of split thickness skin grafts making them useful in various clinical situations. CONCLUSIONS: NPDs are a viable option for both partial and full thickness burns in pediatric patients that do not require transfer to a burn unit. NPDs may be advantageous in highly active children, those with extensive fluid losses, those that require sedation for dressing changes and those that will require grafting.

Efficacy of the stranger safety abduction-prevention program and parent-conducted in situ training.

Using a control group design, we evaluated the effectiveness of the Stranger Safety DVD (The Safe Side, 2004) and parent training of abduction-prevention skills with 6- to 8-year-old children. Children in the training or control group who did not demonstrate the safety skills received in situ training from their parents. There was no significant difference in safety skills between the training and control groups after the training group viewed the DVD. Children in both groups scored significantly better after receiving in situ training, with no significant difference in performance between groups.

The effects of exergaming on physical activity in a third-grade physical education class.

We compared the effects of exergaming and traditional physical education on physical activity among 4 active children who were not overweight and who had experience with the exergaming activities prior to the study. Results showed that exergaming produced substantially higher percentages of physical activity and opportunity to engage in physical activity. In addition, an evaluation of the exergaming equipment showed that exergaming stations were associated with differential levels of physical activity across participants.

The effects of exergaming on physical activity among inactive children in a physical education classroom.

Childhood obesity, which is due in part to lack of physical activity, is a serious concern that requires the attention of the behavioral community. Although excessive video game play has been noted in the literature as a contributor to childhood obesity, newer video gaming technology, called exergaming, has been designed to capitalize on the reinforcing effects of video games to increase physical activity in children. This study evaluated the effects of exergaming on physical activity among 4 inactive children in a physical education (PE) classroom. Results showed that exergaming produced substantially more minutes of physical activity and more minutes of opportunity to engage in physical activity than did the standard PE program. In addition, exergaming was socially acceptable to both the students and the PE teacher. Exergaming appears to hold promise as a method for increasing physical activity among inactive children and might be a possible intervention for childhood obesity.
