Timely transfer of injured children to pediatric trauma centers (PTCs) that can address their unique needs is important. This study was designed to understand the characteristics of transferred injured children. Despite the advantages of care in trauma centers, a significant number of severely injured children are transferred well beyond 2 hours after injury. This study has demonstrated that this pattern of delayed transfer is a systemic problem occurring among all transferring hospitals regardless of distance or mode of patient transfer and is associated with increased use of imaging before transfer.
Crombleholme TM, Lim LY, Habli M, Polzin W, Jaekle R, Michelfelder E, Cnota J, Liu C, Kim MO. Improved recipient survival with maternal nifedipine in twin-twin transfusion syndrome complicated by TTTS cardiomyopathy undergoing selective fetoscopic laser photocoagulation. Am J Obstet Gynecol. 203(4):397.e1-9. 2010.
The purpose of this study was to evaluate the effect of maternal nifedipine on fetal survival when started 24-48 hours before selective fetoscopic laser photocoagulation (SFLP). In conclusion, maternal nifedipine is associated with improved recipient survival in TTTS that undergoes SFLP. This is the first study to suggest a benefit of adjunctive maternal medical therapy in patients with TTTS who undergo SFLP
Kaulfers AM, Bean JA, Inge TH, Dolan LM, Kalkwarf HJ. Bone loss in adolescents after bariatric surgery. Pediatrics. 127(4):e956-61. 2011.
The purpose of this study was to evaluate bone loss in adolescents after Roux-en-Y gastric bypass surgery and to determine the extent to which bone loss was related to weight loss. We hypothesized that adolescents would lose bone mass after surgery and that it would be associated with weight loss. In conclusion, bariatric surgery is associated with significant bone loss in adolescents. Although the predicted bone density was appropriate for age 2 years after surgery, longer follow-up is warranted to determine whether bone mass continues to change or stabilizes.
Levitt MA, Bischoff A, Pena A. Pitfalls and challenges of cloaca repair: how to reduce the need for reoperations. J Pediatr Sugr. 46(6):1250-5. 2011.
Cloacal malformations represent the most complex of genitourinary/anorectal anomalies. We have encountered a unique group of complications in referred patients after failed attempted repairs elsewhere and chose to review this experience with the hope of identifying pitfalls to avoid during the primary repair. We have observed key complications requiring reoperation in a large series of cloacal malformations that are potentially avoidable. A persistent urogenital sinus can be avoided by properly diagnosing a cloaca and repairing the entire malformation and not just the rectum during the initial repair. Vaginal and urethral complications occurred mainly in patients with a common channel longer than 3 cm. Repair of cloacas with common channels longer than 3 cm requires familiarity with a complex decision-making process, and atresias, strictures, and fistulae can be avoided with adequate mobilization of structures and preservation of blood supply. Rectal prolapse occurrence relates to the quality of the perineal muscles. Reoperations can restore the anatomy, but the functional results are not as good as those achieved after primary repair.
Murrell Z, Dickie B, Dasgupta R. Lung nodules in pediatric oncology patients: a prediction rule for when to biopsy. J Pediatr Surg. 46(5):833-7. 2011.  
The purpose of the study was to develop a prediction rule regarding the factors that most accurately predict the diagnosis of a malignancy in a lung nodule in the pediatric oncology patient. In conclusion, lesions that are between 5 and 10 mm in size and peripherally located in patients with osteosarcoma, Ewing sarcoma, or hepatocellular carcinoma are most likely to be malignant. Use of a prediction rule can help guide clinical practice by determining which patients should undergo surgical resection of lung nodules and which patients may be closely observed with continued radiologic studies.

Division Highlights

Molecular Fetal Lab - Timothy Crombleholme, MD

Dr. Crombleholme has expertise in wound healing and fetal cellular and molecular therapeutics research. Dr. Crombleholme is the Director, Surgical Research and Associate Chair of the Children’s Hospital Research Foundation and the Medical Director of the Fetal Care Center.

Solid Organ Cancers - Jason Frischer, MD

Dr. Frischer is continuing his basic science research to study solid organ cancers by identifying, and then overcoming, the mechanisms by which they become resistant to current therapies. Dr. Frischer is the ECMO Director. He intends on applying for a K08 in the fall of 2011.

Intestinal Rehabilitation - Michael Helmrath, MD

Dr. Helmrath has expertise in intestinal rehabilitation. His basic science research continues to focus on intestinal failure and intestinal stem cells. He is studying the mechanisms of intestinal stem cell expansion following resection. His research will help better understand how the cells that continually renew the lining of the intestine every day (intestinal stem cells) increase in number to help compensate following intestinal loss. His research continues to be funded by the NIH as an R01. He has submitted a second R01 which is pending.

Bariatric Surgery - Thomas Inge, MD

The Center for Bariatric Research and Innovation directed by Dr. Inge continues to partner with NIDDK and lead the national effort to prospectively gather data and publish evidence-based recommendations for use of weight loss surgery in adolescents. The team received a renewal of their NIH U01 funded Teen LABS Study, the largest multicenter study to document outcomes of adolescents undergoing weight loss surgery. In addition to this parent grant, the study group has added numerous other R01-funded ancillary studies to the consortium. Dr. Inge also received ARRA funding for Assessing the Health Benefits and Risks of Adolescent Bariatric patients. He has submitted a NIH Competitive renewal to continues this important research.

Molecular Fetal Therapy - Sundeep Keswani, MD

Dr. Keswani’s is focusing on the molecular mechanisms underlying the fetal regenerative wound healing phenotype. If goals are realized, it may yield a wide range of therapeutics for diseases characterized by excessive fibroplasia. His basic science interests in fetal wound healing are closely paired with his clinical practice in fetal surgery and he is currently leading an initiative to create a clinical center of excellence in pediatric wound care. He has submitted his first successful K08 application to the National Institute of Health and is awaiting formal notification of the award.

Biliary Atresia - Gregory Tiao, MD

Dr. Tiao continues to develop his research in biliary atresia. Dr. Tiao received funding on his R01 submission during the past year as he continues his research career progression. Dr. Tiao is the Surgical Director for Liver and Intestinal Transplantation.

Jaimie D. Nathan, MD

Dr. Nathan's research focus is to elucidate the role of the gut microbiome in the modulation of liver injury and cholangiopathies. His studies involve a novel mouse model of small bowel bacterial overgrowth, in which a small bowel self-filling blind loop is surgically created. With this model, he is studying the gut-liver axis as it relates to the pathogenesis of a number of cholangiopathies which can progress to end-stage liver disease. He intends on applying for a K08 in the spring of 2012.

Fetal Therapy - Helen Jones, PhD

Dr. Jones is enhancing the research ongoing in the Center for Molecular Fetal Therapy (CMFT) alongside Dr. Habli. Dr. Jones continues to develop distinct research efforts as well as supporting the rest of the CMFT.
