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.

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.

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.
