A Fatal Twist: Volvulus Of The Small Intestine In A 46-Year-Old Woman, Jared Klein, Kathryn Baxstrom, Stephen Donnelly, Patrick Feasel, Paul Koles

Pediatrics Publications

A 46-year-old woman presented to two emergency departments within 12 hours because of acute abdominal pain. Physical exam demonstrated tenderness and epigastric guarding. An ultrasound was interpreted as negative; she was discharged home. Later that evening, she was found dead. Postmortem exam revealed acute hemorrhagic necrosis of a segment of jejunum secondary to volvulus. Clinical clues suggesting presentations of small bowel volvulus are usually nonspecific; the diagnosis is typically confirmed at surgery. Her unremitting abdominal pain, persistent vomiting, and absolute neutrophilia were consistent with an acute process. The etiology of this volvulus was caused by an elastic fibrous band at …

Γ-Secretase Inhibitor Alleviates Acute Airway Inflammation Of Allergic Asthma In Mice By Downregulating Th17 Cell Differentiation, Weixi Zhang, Xueya Zhang, Anqun Sheng, Cuiye Weng, Tingting Zhu, Wei Zhao, Changchong Li

Pediatrics Publications

T helper 17 (Th17) cells play an important role in the pathogenesis of allergic asthma. Th17 cell differentiation requires Notch signaling. γ-Secretase inhibitor (GSI) blocks Notch signaling; thus, it may be considered as a potential treatment for allergic asthma. The aim of this study was to evaluate the effect of GSI on Th17 cell differentiation in a mouse model of allergic asthma. OVA was used to induce mouse asthma model in the presence and absence of GSI. GSI ameliorated the development of OVA-induced asthma, including suppressing airway inflammation responses and reducing the severity of clinical signs. GSI also significantly …

Success With Extended-Infusion Meropenem After Recurrence Of Baclofen Pump-Related Achromobacter Xylosoxidans Meningitis In An Adolescent, Kristen R. Nichols, Chad A. Knoderer, Nicholas G. Jackson, John J. Manaloor, John C. Christenson

Scholarship and Professional Work – COPHS

A 13-year-old female experienced a recurrence of baclofen pump-related central nervous system (CNS) infection caused by Achromobacter, despite absence of retained foreign material. Due to the failure of meropenem (120 mg/kg/d in divided doses every 8 hours and infused over 30 minutes) in the initial infection, the dose was infused over 4 hours during the recurrence. Meropenem is an antibiotic for which efficacy is time dependent, and 4-hour versus 30-minute infusions have been shown to prolong the time the concentration of the antibiotic exceeds the minimum inhibitory concentration (MIC) of the organism at the site of infection (T>MIC). …

Absolute Reticulocyte Count Acts As A Surrogate For Fetal Hemoglobin In Infants And Children With Sickle Cell Anemia., Emily Riehm Meier, Colleen Byrnes, Maxine Weissman, Y Terry Lee, Jeffery L Miller

Pediatrics Faculty Publications

Hemoglobin switching is largely complete in humans by six months of age. Among infants with sickle cell anemia (HbSS, SCA), reticulocytosis begins early in life as fetal hemoglobin (HbF) is replaced by sickle hemoglobin (HbS). The objective of this study was to determine if absolute reticulocyte count (ARC) is related to HbF levels in a cohort of pediatric SCA patients. A convenience sample of 106 children with SCA between the ages of 1 month and 20 years who were not receiving hydroxyurea or monthly blood transfusions were enrolled in this observational study. Hematologic data, including ARC and HbF levels, were …

Nfkb1 Activation By The E26 Transformation-Specific Transcription Factors Pu.1 And Spi-B Promotes Toll-Like Receptor-Mediated Splenic B Cell Proliferation, Stephen K.H. Li, Ali K. Abbas, Lauren A. Solomon, Gaëlle M.N. Groux, Rodney P. Dekoter

Paediatrics Publications

Generation of antibodies against T-independent and T-dependent antigens requires Toll-like receptor (TLR) engagement on B cells for efficient responses. However, the regulation of TLR expression and responses in B cells is not well understood. PU.1 and Spi-B (encoded by Sfpi1 and Spib, respectively) are transcription factors of the E26 transformation-specific (ETS) family and are important for B cell development and function. It was found that B cells from mice knocked out for Spi-B and heterozygous for PU.1 (Sfpi1^+/- Spib^-/- [PUB] mice) proliferated poorly in response to TLR ligands compared to wild-type (WT) B cells. The NF-κB family member …

Impact Of Prenatal Environmental Stress On Cortical Development, Seiji Ishii, Kazue Hashimoto-Torii

Pediatrics Faculty Publications

Prenatal exposure of the developing brain to various types of environmental stress increases susceptibility to neuropsychiatric disorders such as autism, attention deficit hyperactivity disorder and schizophrenia. Given that even subtle perturbations by prenatal environmental stress in the cerebral cortex impair the cognitive and memory functions, this review focuses on underlying molecular mechanisms of pathological cortical development. We especially highlight recent works that utilized animal exposure models, human specimens or/and induced Pluripotent Stem (iPS) cells to demonstrate: 1. molecular mechanisms shared by various types of environmental stressors, 2. the mechanisms by which the affected extracortical tissues indirectly impact the cortical development …

Dual Transcriptomic Profiling Of Host And Microbiota During Health And Disease In Pediatric Asthma., Marcos Pérez-Losada, Eduardo Castro-Nallar, Matthew L. Bendall, Robert J. Freishtat, Keith A. Crandall

Pediatrics Faculty Publications

BACKGROUND: High-throughput sequencing (HTS) analysis of microbial communities from the respiratory airways has heavily relied on the 16S rRNA gene. Given the intrinsic limitations of this approach, airway microbiome research has focused on assessing bacterial composition during health and disease, and its variation in relation to clinical and environmental factors, or other microbiomes. Consequently, very little effort has been dedicated to describing the functional characteristics of the airway microbiota and even less to explore the microbe-host interactions. Here we present a simultaneous assessment of microbiome and host functional diversity and host-microbe interactions from the same RNA-seq experiment, while accounting for …

Integrating Microbial And Host Transcriptomics To Characterize Asthma-Associated Microbial Communities., Eduardo Castro-Nallar, Ying Shen, Robert J. Freishtat, Marcos Pérez-Losada, Solaiappan Manimaran, Et Al.

Pediatrics Faculty Publications

BACKGROUND: The relationships between infections in early life and asthma are not completely understood. Likewise, the clinical relevance of microbial communities present in the respiratory tract is only partially known. A number of microbiome studies analyzing respiratory tract samples have found increased proportions of gamma-Proteobacteria including Haemophilus influenzae, Moraxella catarrhalis, and Firmicutes such as Streptococcus pneumoniae. The aim of this study was to present a new approach that combines RNA microbial identification with host gene expression to characterize and validate metagenomic taxonomic profiling in individuals with asthma.

METHODS: Using whole metagenomic shotgun RNA sequencing, we characterized and compared the microbial …

Pharmacologically-Induced Mitotic Synchrony In Airway Epithelial Cells As A Mechanism Of Action Of Anti-Inflammatory Drugs, Robert J. Freishtat, Gustavo Nino, Y. Tsegaye, Sarah E. Alcala, Angela S. Benton, Alan M. Watson, E.K.M. Reeves, S. K. Haider, Jesse M. Damsker

Pediatrics Faculty Publications

Background

Mitotic synchrony is the synchronous progression of a population of cells through the cell cycle and is characteristic of non-diseased airway epithelial cells. However, we previously showed that asthmatic airway epithelial cells are characterized by mitotic asynchrony and are pro-inflammatory as a result. Glucocorticoids can induce mitotic synchrony that in turn suppresses the pro-inflammatory state of diseased cells, suggesting a novel anti-inflammatory mechanism of action. Herein, we benchmarked traditional glucocorticoids against the ability of a new clinical-stage dissociative steroidal drug, VBP15, for mitotic resynchronization and associated anti-inflammatory activity in asthmatic airway epithelial cells.

Methods

Primary airway epithelial cells differentiated …

Necrotizing enterocolitis (NEC) is a devastating gastrointestinal emergency. The purpose of this study is to determine if functional single nucleotide polymorphisms (SNPs) in immune-modulating genes pre-dispose infants to NEC. After Institutional Review Board approval and parental consent, buccal swabs were collected for DNA extraction. TaqMan allelic discrimination assays and BglII endonuclease digestion were used to genotype specific inflammatory cytokines and TRIM21. Statistical analysis was completed using logistic regression. 184 neonates were analyzed in the study. Caucasian neonates with IL-6 (rs1800795) were over 6 times more likely to have NEC (p = 0.013; OR = 6.61, 95% CI 1.48-29.39), and over …

She developed fussiness lasting two hours, not associated with cyanosis, and not relieved by feeding. Her pulse oximetry was 88% while breathing room air, and she had no differential blood pressure gradient.

Prevalence Of Vitamin D Deficiency In Exclusively Breastfed Infants At The Aga Khan University Hospital, Nairobi, Nusrat. A. Said

Master of Medicine in Paediatrics and Child Health

Introduction: Vitamin D deficiency in infants is a recognized cause of rickets. In the last few years, evidence has emerged of its association with lower respiratory tract infections, food allergy, type 1 diabetes, schizophrenia and various other extra skeletal health effects. Exclusively breastfed infants are especially vulnerable to vitamin D deficiency due to their dependence on previous trans-placental transfer of vitamin D from the mother, dietary vitamin D from breast milk and cutaneous synthesis of vitamin D on exposure to sunlight. The worldwide epidemic of Vitamin D deficiency in pregnancy and the low content of vitamin D in breast milk …
