Percutaneous Transhepatic Cholecysto-Cholangiography (Ptcc): An Alternative To Intraoperative Cholangiography In High Risk Infants Suspect For Biliary Atresia, Joseph Sujka, Katrina L. Weaver, Ashwini S. Poola, Douglas C. Rivard, Richard J. Hendrickson

Manuscripts, Articles, Book Chapters and Other Papers

Infants with cholestasis and conjugated hyperbilirubinemia persisting beyond two weeks of age must be evaluated promptly to exclude biliary atresia (BA). BA progresses to cirrhosis and liver failure if portoenterostomy (PE) is not performed in a timely fashion. The gold standard to diagnose BA is intraoperative cholangiography (IOC) via laparotomy. Neonates that are critically ill or have significant co-morbidities may be high-risk surgical candidates, and thus minimizing operative time or avoiding an operation may be beneficial. An additional modality for excluding BA is percutaneous transhepatic cholecysto-cholangiography (PTCC). We present three infants undergoing PTCC by interventional radiology (IR) revealing patency of …

Manuscripts, Articles, Book Chapters and Other Papers

Intestinal mucus layer disruption and gut microflora modification in conjunction with tight junction (TJ) changes can increase colonic permeability that allows bacterial dissemination and intestinal and systemic disease. We showed previously that Citrobacter rodentium (CR)-induced colonic crypt hyperplasia and/or colitis is regulated by a functional cross-talk between the Notch and Wnt/β-catenin pathways. In the current study, mucus analysis in the colons of CR-infected (108 CFUs) and Notch blocker Dibenzazepine (DBZ, i.p.; 10μmol/Kg b.w.)-treated mice revealed significant alterations in the composition of trace O-glycans and complex type and hybrid N-glycans, compared to CR-infected mice alone that preceded/accompanied alterations in 16S rDNA …

Pharmacokinetics Of Ferric Pyrophosphate Citrate Administered Via Dialysate And Intravenously To Pediatric Patients On Chronic Hemodialysis., Raymond D. Pratt, Sarah Grimberg, Joshua J. Zaritsky, Bradley A. Warady

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Iron deficiency is a common cause of anemia in pediatric patients with hemodialysis-dependent chronic kidney disease (CKD-5HD). Ferric pyrophosphate citrate (FPC, Triferic®) donates iron directly to transferrin, bypassing the reticuloendothelial system and avoiding iron sequestration. Administration of FPC via dialysate or intravenously (IV) may provide a suitable therapeutic option to current IV iron preparations for these patients.

METHODS: The pharmacokinetics and safety of FPC administered via dialysate and IV to patients aged < 6 years (n = 3), 6 to < 12 years (n = 4), and 12 to < 18 years (n = 15) were investigated in a multicenter, open-label, two-period, single-dose study. FPC (0.07 mg iron/kg) was infused IV into the venous blood return line during hemodialysis session no. 1. FPC iron was added to bicarbonate concentrate to deliver 2 μM (110 μg/L) iron via dialysate during hemodialysis session no. 2.

RESULTS: Mean serum total iron concentrations peaked 3 to 4 h after administration via dialysate and 2 to 4 h after IV administration and returned to baseline …

Nadolol In Pregnancy: A Medical Student’S Reflection On Her Pregnancy, Rebecca King-Mallory, Shawndra Barker, Kaitlin Mcgrogan, Adam M. Franks

Marshall Journal of Medicine

Hypertension is a common concern during pregnancy. Beta-blockers are one potential treatment, but third trimester exposure has correlated with an increased risk of perinatal events. Nadolol, a nonselective beta blocker, has properties that differ from those of its selective counterparts, including longer half-life, decreased protein binding, and renal excretion in the unchanged form. There is very limited data on the use of nadolol during pregnancy, and its safety has not been completely evaluated. This case study documents the perinatal outcomes of nadolol use throughout a medical student’s pregnancy and explores the experience in obtaining and undergoing medical care.

Handwriting And Occupational Therapy In The Schools, Anne H. Zachry, L. Woods

Faculty Presentations

Handwriting is an important life skill, and handwriting tasks take up a significant amount of time during the school day. Research suggests that writing by hand influences reading skills, recall, academics, and motor and composition skills. Pediatric occupational therapists evaluate and treat children who are struggling with handwriting; therefore, it is important for practitioners to be aware of a variety of treatment strategies for addressing handwriting challenges. After participating in this session, the learner will be able to discuss the research on typical and atypical pencil grasps, identify and name 5 common handwriting errors, and explain 3 techniques for increasing …

The Evidence For The Benefits From Breast Milk In The Neurodevelopment Of Premature Babies – A Review Of The Recent Literature, Danuta Iulia Paduraru

Journal of Mind and Medical Sciences

Introduction. The brain in preterm babies is usually not fully developed and therefore early post-term events can have long-lasting neurodevelopment and cognitive outcomes. It is known that cerebral white matter connectivity is important for later intact cognitive functioning amongst children born very preterm and that breast milk imparts neurotrophic factors. The relationship between breastfeeding and child development is a long and well-studied area, and the evidence in support of breast milk is already substantial. Here we review the recent literature on the topic to establish whether additional evidence is available to strengthen the view that breast milk is superior in …

Metaanalysis Of The Relationship Between Violent Video Game Play And Physical Aggression Over Time, Anna T. Prescott, James Sargent, Jay G. Hull

Dartmouth Scholarship

To clarify and quantify the influence of video game violence (VGV) on aggressive behavior, we conducted a metaanalysis of all prospective studies to date that assessed the relation between exposure to VGV and subsequent overt physical aggression. The search strategy identified 24 studies with over 17,000 participants and time lags ranging from 3 months to 4 years. The samples comprised various nationalities and ethnicities with mean ages from 9 to 19 years. For each study we obtained the standardized regression coefficient for the prospective effect of VGV on subsequent aggression, controlling for baseline aggression. VGV was related to aggression using …

Factors Associated With Substance Use Among Adolescents Living With Hiv In Kenya, Wambui Kagucia

Master of Medicine in Paediatrics and Child Health

Background: Substance use is rife in our society and adolescents (10-19 years) do face this problem during this vulnerable period of growth and development. Use of substances is known to be associated with poor health choices and risky sexual behaviour. Since the advent of antiretroviral therapy (ART), significant progress has been made with reduced rates of mother to child transmission (MTCT) and a general downward global trend in acquired immunodeficiency disease (AIDS) related mortalities. However, human immunodeficiency virus (HIV)/AIDS is still a leading cause of mortality in adolescents living in Sub Saharan Africa, with an upward trend in new HIV …

IMPROVING COMMUNICATION BETWEEN CHILD LIFE SERVICES AND NURSING ON AN INPATIENT HOSPITAL UNIT

Effective communication between patient caregivers has been shown to reduce stress and trauma related to hospitalization and subsequent improved outcomes. An HCAHP score for a 30 bed acute inpatient pediatric unit illustrated the confusion faced by children as a result of nursing and care life specialists not working together as a team.

A root cause analysis identified a number of issues as to why patients were not benefitting fully from child life services. Several counter measures were instituted with the goals of improving the HCAHP score and …

Developmental Intervention Patters In A Level Iv Neonatal Intensive Care Unit (Nicu), Grace Winningham, Cy Nadler, Sarah Nyp, Eugenia K. Pallotto, Ashley Sherman

Posters

Background: There are no evidence-based standards for if/when developmental interventions should be initiated while an infant is in the neonatal intensive care unit (NICU), or these services yield incremental benefit. To support future prospective studies evaluating the neurodevelopmental benefits of NICU-based services as well as standardizing protocols for developmental interventions in the NICU, a thorough descriptive investigation of current developmental intervention practices is necessary. Objective: To describe trends in the delivery of developmental interventions [physical therapy (PT), occupational therapy (OT), speech-language therapy (ST), child life (CL), and music therapy (MT)] in high-risk infants in a large level-IV NICU. Methods: Electronic …

Manuscripts, Articles, Book Chapters and Other Papers

Hepatoblastoma (HB) is the most common malignant liver tumor in children. Although survival of patients has improved significantly over the last 2 decades, a significant number of patients do not respond to standard chemotherapy. We conducted a pilot study to understand if there was immunophenotypic difference between tumors that respond well to chemotherapy versus that do not. We selected 10 cases of HB from children presenting at our hospital. All patients had initial tissue diagnosis, underwent chemotherapy followed by surgical resection. The cases were divided into 2 groups: aggressive group with 5 cases (all of which had a poor response …

Pediatric Obesity: Influence On Drug Dosing And Therapeutics, Barbara Ameer Pharmd, Mba, Bcps, Fcp, Michael Weintraub Md

Department of Medicine Faculty Papers

Obesity is an ongoing global health concern and has only recently been recognized as a chronic disease of energy homeostasis and fuel partitioning. Obesity afflicts 17% of US children and adolescents. Severe obesity (³120% of the 95^th percentile of BMI-for-age, or a BMI of ³35 kg/m²) is the fastest growing subgroup and now approaches 6% of all US youth. Health consequences (e.g., type 2 diabetes, coronary heart disease) are related in a dose-dependent manner to severity of obesity. Since therapeutic interventions are less effective in severe obesity, prevention is a high priority.

Clinical Perspective On Passive Audio Vocal Measurement In The Evaluation Of Selective Mutism., Helen Y Xu, Jacob Stroud, Renee K. Jozanovic, Jon Clucas, Jake Jungwoo Son, Bonhwang Koo, Juliet Schwarz, Arno Klein, Rachel Busman, Michael P. Milham

Student Papers, Posters & Projects

Selective Mutism (SM) is an anxiety disorder often diagnosed in early childhood and characterized by persistent failure to speak in certain social situations but not others. Diagnosing SM and monitoring treatment response can be quite complex, due in part to changing definitions of and scarcity of research about the disorder. Subjective self-reports and parent/teacher interviews can complicate SM diagnosis and therapy, given that similar speech problems of etiologically heterogeneous origin can be attributed to SM. The present perspective discusses the potential for passive audio capture to help overcome psychiatry's current lack of objective and quantifiable assessments in the context of …
