Environmental Enteropathy In Undernourished Pakistani Children: Clinical And Histomorphometric Analyses, Sana Syed, Sunil Yeruva, Jeremy Herrmann, Anne Sailer, Kamran Sadiq, Najeeha Talat Iqbal, Furqan Kabir, Kumail Ahmed, Shahida Qureshi, Syed Asad Ali

Department of Paediatrics and Child Health

Despite nutrition interventions, stunting thought to be secondary to underlying environmental enteropathy (EE) remains pervasive among infants residing in resource-poor countries and remains poorly characterized. From a birth cohort of 380 children, 65 malnourished infants received 12 weeks of nutritional supplementation with ready-to-use therapeutic food (RUTF). Eleven children with insufficient response to RUTF underwent upper endoscopy with duodenal biopsies, which were compared with U.S., age-matched specimens for healthy, celiac disease, non-celiac villous atrophy, non-celiac intraepithelial lymphocytosis, and graft-versus-host disease patients. Of the 11 children biopsied, EE was found in 10 (91%) with one subject with celiac disease. Morphometry demonstrated decreased …

Feasibility And Effect Of Life Skills Building Education And Multiple Micronutrient Supplements Versus The Standard Of Care On Anemia Among Non-Pregnant Adolescent And Young Pakistani Women (15-24 Years): A Prospective, Population-Based Cluster-Randomized Trial, Jo-Anna B. Baxter, Yaqub Wasan, Sajid Bashir Soofi, Zamir Suhag, Zulfiqar Ahmed Bhutta

Department of Paediatrics and Child Health

Background: Adolescence is a critical period for physical and psychological growth and development, and vitamin and mineral requirements are correspondingly increased. Health and health behaviours correspond strongly from adolescence to adulthood. Developing a preconception care package for adolescent and young women in resource-limited settings could serve to empower them to make informed decisions about their nutrition, health, and well-being, as well as function as a platform for the delivery of basic nutrition-related interventions to address undernutrition.
Methods: In this population-based two-arm, cluster-randomized, controlled trial of life skills building education (provided bi-monthly) and multiple micronutrient supplementation (provided twice-weekly; UNIMMAP composition), we …

Pediatrics Faculty Publications

BACKGROUND: Electroencephalography at hospital presentation may offer important insights regarding prognosis that can inform understanding of cerebral malaria (CM) pathophysiology and potentially guide patient selection and risk stratification for future clinical trials. Electroencephalogram (EEG) findings in children with CM in Uganda and Malawi were compared and associations between admission EEG findings and outcome across this diverse population were assessed. Demographic, clinical and admission EEG data from Ugandan and Malawian children admitted from 2009 to 2012 with CM were gathered, and survivors assessed for neurological abnormalities at discharge.

RESULTS: 281 children were enrolled (Uganda n = 122, Malawi n = 159). …

INTRODUCTION: Children with acute respiratory tract infections (ARTIs) are prescribed up to 11.4 million unnecessary antibiotic prescriptions annually. Inadequate parent-provider communication is a chief contributor, yet efforts to reduce overprescribing have only indirectly targeted communication or been impractical. This paper describes our multisite, parallel group, cluster randomised trial comparing two feasible interventions for enhancing parent-provider communication on the rate of inappropriate antibiotic prescribing (primary outcome) and revisits, adverse drug reactions and parent-rated quality of shared decision-making, parent-provider communication and visit satisfaction (secondary outcomes).

METHODS/ANALYSIS: We will attempt to recruit all eligible paediatricians and nurse practitioners (currently 47) at an academic …

Trpv1 And The Mcp-1/Ccr2 Axis Modulate Post-Uti Chronic Pain., John Rosen, Ryan E. Yaggie, Patrick J. Woida, Richard J. Miller, Anthony J. Schaeffer, David J. Klumpp

Manuscripts, Articles, Book Chapters and Other Papers

The etiology of chronic pelvic pain syndromes remains unknown. In a murine urinary tract infection (UTI) model, lipopolysaccharide of uropathogenic E. coli and its receptor TLR4 are required for post-UTI chronic pain development. However, downstream mechanisms of post-UTI chronic pelvic pain remain unclear. Because the TRPV1 and MCP-1/CCR2 pathways are implicated in chronic neuropathic pain, we explored their role in post-UTI chronic pain. Mice were infected with the E. coli strain SΦ874, known to produce chronic allodynia, and treated with the TRPV1 antagonist capsazepine. Mice treated with capsazepine at the time of SΦ874 infection failed to develop chronic allodynia, whereas …

Facilitating The Everyday Steward: Impact Of Mandatory Antimicrobial Indication/Duration And A 48 Hour Time Out, Ann L. Wirtz, Alaina N. Burns, Brian R. Lee, Tammy Frank, Laura Fitzmaurice, Richard Ogden, Brian O'Neal, Jennifer Goldman

Posters

Introduction: Required indication, duration, and a 48-hour antimicrobial timeout are an integral part of antimicrobial stewardship standards; however, limited data are available to demonstrate an effect on antimicrobial utilization and antimicrobial stewardship practice. Therefore, we evaluated the impact of mandatory declared indication/duration along with a pharmacy-driven 48-hour timeout on antimicrobial utilization and antimicrobial stewardship interventions.

Methods: We performed a retrospective evaluation of ASP interventions and antimicrobial use following implementation of mandatory antimicrobial indication/duration at the point of computerized physician order entry (CPOE). A pharmacist-driven 48-hour antimicrobial timeout was introduced on the same date. This study was conducted at Children’s Mercy …

6-Day-Old Term Infant With Fever And Lethargy, Gangaram Akangire, Archana Kulkarni, Winston M. Manimtim

Manuscripts, Articles, Book Chapters and Other Papers

Osteomyelitis in the neonatal period can be a diagnostic challenge, especially if it is mimicking brachial plexus palsy. We present a unique case of 6-day-old term infant with lethargy and fever diagnosed with Group B Streptococci (GBS) sepsis and meningitis. Few days later, infant developed right arm immobility leading to hematogenous spread of GBS to right humerus, leading to osteomyelitis and septic arthritis. Infant was treated with intravenous Ampicillin for 4 weeks with full arm mobility and full recovery from sepsis and meningitis. This case provides several clinical vignettes that may be crucial in timely diagnosis and treatment of osteomyelitis …

Evaluating The Effectiveness Of Text Messaging And Phone Call Reminders To Minimize No Show At Pediatric Outpatient Clinics In Pakistan: Protocol For A Mixed-Methods Study, Sana Saeed, Noureen Somani, Fatima Sharif, Abdul Momin Kazi

Department of Paediatrics and Child Health

Background: Missing health care appointments without canceling in advance results in a no show, a vacant appointment slot that cannot be offered to others. No show can be reduced by reminding patients about their appointment in advance. In this regard, mobile health (mHealth) strategy is to use text messaging (short message service, SMS), which is available on all cellular phones, including cheap low-end handsets. Nonattendance for appointments in health care results in wasted resources and disturbs the planned work schedules.
Objectives: The purpose of this study is to evaluate the efficacy of the current text messaging (SMS) and call-based …

Weldon, M. Steven Oberste, Syed S. Zaidi, Muhammad M. Alam, Anita K. M. Zaidi

Department of Paediatrics and Child Health

Background: Outbreaks of circulating vaccine derived polioviruses type 2 (cVDPV2) remain a risk to poliovirus eradication in an era without live poliovirus vaccine containing type 2 in routine immunization. We evaluated existing outbreak response strategies recommended by the World Health Organization (WHO) for control of cVDPV2 outbreaks.
Methods: Seronegative children for poliovirus type 2 (PV2) at 22 weeks of life were assigned to one of four study groups and received respectively (1) one dose of trivalent oral poliovirus vaccine (tOPV); (2) monovalent OPV 2 (mOPV2); (3) tOPV together with a dose of inactivated poliovirus vaccine (IPV); or (4) mOPV2 with …

P16-Ki67-Hmb45 Immunohistochemical Profiling May Help Discriminate Between Spitzoid Melanoma And Atypical Spitz Nevi, Robert E. Garola, Vivekanand Singh

Posters

Background

When Spitz nevi have increased vertical thickness (>1.5 MM), show ulceration and deep seated mitosis, the differential diagnostic considerations of atypical Spitz nevus (ASN) or a Spitzoid melanoma (SM) enter into consideration. While expert consultation from a dermatopathologist is most often sought to resolve the differential diagnosis, it could be expensive and time consuming. Recently, the use of molecular genetic testing has also been advocated in the work group up of atypical melanocytic proliferations. On the contrary, immunohistochemistry is a more routinely used technique in most pathology centers may be more simple to apply. A single immunohistochemical marker …

Rotavirus Vaccine Response Correlates With The Infant Gut Microbiota Composition In Pakistan, Vanessa Harris, Syed Asad Ali, Susana Fuentes, Abdul Momin Kazi, Jacqueline Tate, Umesh Parashar, W. Joost Wiersinga, Carlo Giaquinto, Carolina De Weerth, Willem M. De Vos

Department of Paediatrics and Child Health

Rotavirus (RV) is the leading cause of diarrhea-related death in children worldwide and ninety-five percent of rotavirus deaths occur in Africa and Asia. Rotavirus vaccines (RVV) can dramatically reduce RV deaths, but have low efficacy in low-income settings where they are most needed. The intestinal microbiome may contribute to this decreased RVV efficacy. This pilot study hypothesizes that infants' intestinal microbiota composition correlates with RVV immune responses and that RVV responders have different gut microbiota as compared to non-responders. We conducted a nested, matched case-control study comparing the pre-vaccination intestinal microbiota composition between 10 6-week old Pakistani RVV-responders, 10 6-week …

Relationships Among Common Illness Symptoms And The Protective Effect Of Breastfeeding In Early Childhood In Mal-Ed: An Eight-Country Cohort Study, Stephanie A. Richard, Benjamin J. J. Mccormick, Jessica C. Seidman, Zeba Rasmussen, Margaret N. Kosek, Elizabeth T. Rogawski, William Petri, Anurahda Bose, Zulfiqar Ahmed Bhutta, Ali Turab

Department of Paediatrics and Child Health

Children in low-income countries experience multiple illness symptoms in early childhood. Breastfeeding is protective against diarrhea and respiratory infections, and these illnesses are thought to be risk factors of one another, but these relationships have not been explored simultaneously. In the eight-site MAL-ED study, 1,731 infants were enrolled near birth and followed for 2 years. We collected symptoms and diet information through twice-weekly household visits. Poisson regression was used to determine if recent illness history was associated with incidence of diarrhea or acute lower respiratory infections (ALRI), accounting for exclusive breastfeeding. Recent diarrhea was associated with higher risk of incident …

Department of Paediatrics and Child Health

Environmental Enteric Dysfunction (EED), a syndrome characterized by chronic gut inflammation, contributes towards stunting and poor response to enteric vaccines in children in developing countries. In this study, we evaluated major putative biomarkers of EED using growth faltering as its clinical proxy. Newborns (n = 380) were enrolled and followed till 18 months with monthly anthropometry. Biomarkersassociated with gut and systemic inflammation were assessed at 6 and 9 months. Linear mixed effects model was used to determine the associations of these biomarkers with growth faltering between birth and 18 months. Fecal myeloperoxidase (neutrophil activation marker) at 6 months [β = …

Rapid Intravenous Rehydration Of Children With Acute Gastroenteritis And Dehydration: A Systematic Review And Meta-Analysis, M. A. Iro, T. Sell, N. Brown, K. Maitland

Department of Paediatrics and Child Health

Background: The World Health Organization (WHO) recommends rapid intravenous rehydration, using fluid volumes of 70-100mls/kg over 3–6 h, with some of the initial volume given rapidly as initial fluid boluses to treat hypovolaemic shock for children with acute gastroenteritis (AGE) and severe dehydration. The evidence supporting the safety and efficacy of rapid versus slower rehydration remains uncertain.
Methods: We conducted a systematic review of randomised controlled trials (RCTs) on 11th of May 2017 comparing different rates of intravenous fluid therapy in children with AGE and moderate or severe dehydration, using standard search terms. Two authors independently assessed trial quality and …
