Background: Dalbavancin is a novel lipoglycopeptide antibiotic that has potent in vitro activity against Gram-positive microorganisms.

Methods: We performed a phase 1, open-label, multicenter study to investigate the pharmacokinetics (PK) and safety of a single dose of intravenous dalbavancin in hospitalized pediatric subjects 3 months to 11 years of age. We combined these data with previously collected adolescent PK data and performed a population PK analysis.

Phase I Study Assessing the Pharmacokinetic Profile, Safety, and Tolerability of a Single Dose of Ceftazidime-Avibactam in Hospitalized Pediatric Patients.

This study aimed to investigate the pharmacokinetics (PK), safety, and tolerability of a single dose of ceftazidime-avibactam in pediatric patients. A phase I, multicenter, open-label PK study was conducted in pediatric patients hospitalized with an infection and receiving systemic antibiotic therapy. Patients were enrolled into four age cohorts (cohort 1, ≥12 to <18 years; cohort 2, ≥6 to <12 years; cohort 3, ≥2 to <6 years; cohort 4, ≥3 months to <2 years).

Family Presence During Pediatric Tracheal Intubations.

Importance: Family-centered care, which supports family presence (FP) during procedures, is now a widely accepted standard at health care facilities that care for children. However, there is a paucity of data regarding the practice of FP during tracheal intubation (TI) in pediatric intensive care units (PICUs). Family presence during procedures in PICUs has been advocated.

Congenital myotonic dystrophy: ventriculomegaly and shunt considerations for the pediatric neurosurgeon.

Purpose: Ventriculomegaly in infants with congenital myotonic dystrophy (CDM) is common, and the neurosurgical determination of shunting is complex. The natural history of CDM-associated ventriculomegaly from prenatal to natal to postnatal stages is poorly known. The relationship between macrocephaly and ventriculomegaly, incidence of shunt necessity, and early mortality outcomes lack pooled data analysis.

Variability in the structure and care processes for critically injured children: A multicenter survey of trauma bay and intensive care units.

Purpose: Evaluate national variation in structure and care processes for critically injured children.

Methods: Institutions with pediatric intensive care units (PICUs) that treat trauma patients were identified through the Virtual Pediatric Systems (n=72). Prospective survey data were obtained from PICU and Trauma Directors (n=69, 96% response).

Endoscopic Endonasal Repair of Congenital Defects of the Anterior Skull Base: Developmental Considerations and Surgical Outcomes.

Techniques of endoscopic endonasal surgery, initially developed primarily for intracranial neoplasms, have been adapted to treat a wide variety of pathologies previously addressed with open craniotomy including congenital and acquired defects of the anterior skull base. Congenital defects can lead to herniation of leptomeninges containing cerebrospinal fluid alone or with brain tissue. Specific types of encephalocele can be defined on the basis of the associated abnormal bony anatomy.

Meningiomas of the pediatric skull base: a review.

Pediatric skull base meningiomas are rare and complex clinical entities. Meningioma is a relatively uncommon brain tumor in children, and only ∼ 27% involve the skull base. Some evidence suggests that these tumors are more likely to be atypical or malignant in children than adults.

Pharmacokinetics, Safety and Tolerability of Single Dose Dalbavancin in Children 12-17 Years of Age.

Background: Dalbavancin is a lipoglycopeptide antibiotic with Gram-positive activity and novel pharmacokinetic (PK) properties that result in a prolonged terminal half-life of 15.5 days in adults. Once weekly dosing in adults in phase 3 studies of complicated skin and skin structure infections documented dalbavancin exposures associated with clinical and microbiologic efficacy.

Variants in C-reactive protein and IL-6 genes and susceptibility to obstructive sleep apnea in children: a candidate-gene association study in European American and Southeast European populations.

Background: Preliminary evidence indicates that variants of the C-reactive protein (CRP) and IL-6 genes might be associated with the presence of obstructive sleep apnea (OSA) in childhood. Thus a candidate-gene association study was conducted to investigate the association of four variants of the CRP gene (1444C/T, -717T/C, 1861C/T, and 1919A/T) and two variants of the IL-6 gene (-174G/C and 597G/A) with OSA in a cohort of European American and Greek children.

Methods: The genetic risk effects were estimated based on the odds ratio (OR) of the allele contrast and the generalized odds ratio (ORG), which is a model-free approach.

Selective dorsal rhizotomy for spasticity not associated with cerebral palsy: reconsideration of surgical inclusion criteria.

Children with spastic diplegia from cerebral palsy (CP) experience measurable improvement in their spasticity and motor function following selective dorsal rhizotomy (SDR). The role of this operation in the treatment of other spasticity causes is less well defined. A literature review was undertaken to survey outcomes from SDRs performed outside the CP population.

Complications associated with molding helmet therapy for positional plagiocephaly: a review.

Molding helmet therapy is a widely accepted treatment for positional plagiocephaly that is generally considered to be low risk. Multiple large outcome studies have shown good results, but adverse events are rarely reported. The literature on helmet therapy was reviewed to clarify the clinical experience with associated complications.

Extracorporeal photopheresis for the treatment of severe, refractory steroid dependent pediatric Crohn's Disease.

Crohn's disease is a chronic, inflammatory disease of the gastrointestinal tract, affecting both children and adults. Extracorporeal photopheresis (ECP) has been used in steroid dependent adults with moderate to severely active Crohn's disease, with response rates up to 50%, with up to 25% complete responses. A 12-year-old male patient had severe unremitting Crohn's disease for one year, despite treatment with anti-inflammatory, immunosuppressive, and biologic agents.

Pharmacokinetics, safety profile, and efficacy of aliskiren in pediatric patients with hypertension.

Objective: To assess the pharmacokinetics (PK) and safety profile of aliskiren in pediatric patients (6-17 years old) with hypertension.

Methods: Patients were randomized to a single weight-based dose of either 2 mg/kg (n = 19) or 6 mg/kg (n = 20) of aliskiren daily for 8 days. The PK, pharmacodynamics, safety profile, and efficacy of aliskiren were assessed.

Dietary and physical activity patterns in children with obstructive sleep apnea.

Objective: To assess dietary and physical activity patterns and morning circulating blood levels of the orexigenic hormones ghrelin and visfatin in children with either obesity, obstructive sleep apnea (OSA), or both conditions.

Study Design: In this cross-sectional design, 5- to 9-year-old participants (n = 245) from the community were identified. After overnight polysomnography, caregivers filled out a food and physical activity questionnaire, and the child underwent a fasting blood draw for ghrelin and visfatin plasma levels.

Pediatric obstructive sleep apnea: a potential late consequence of respiratory syncitial virus bronchiolitis.

Study Objectives: To examine the hypothesis that children who suffered from severe respiratory syncitial virus (RSV) bronchiolitis during infancy may be at higher risk for obstructive sleep apnea (OSA) later in childhood.

Methods: Survey of Kosair Children's Hospital medical records allowed for identification of potential candidates for the study. Twenty-one randomly selected children (mean age +/- SD: 5.

Catecholamine alterations in pediatric obstructive sleep apnea: effect of obesity.

Study Objectives: Obstructive sleep apnea (OSA) elicits increased sympathetic activity in adults and increased urinary catecholamines. Moreover, urinary catecholamine excretion is altered in obese patients. We hypothesized that morning urine catecholamine levels would be correlated with the severity of obstructive sleep apnea and degree of obesity in children.

Leukotriene pathways and in vitro adenotonsillar cell proliferation in children with obstructive sleep apnea.

Introduction: The abundant expression of leukotrienes (LTs) and their receptors in adenotonsillar tissues of children with obstructive sleep apnea (OSA) suggest that LT antagonists could be useful in treating OSA.

Methods: The effects of LTD4 and of LT receptor antagonists zileuton, montelukast, and BAY u9773 were examined on mixed cell cultures prepared from dissociated tonsils or adenoids harvested intraoperatively from children with polysomnographically diagnosed OSA. Proliferation was assessed by (3)[H]-thymidine incorporation, and inflammatory cytokine production (tumor necrosis factor [TNF]-alpha, interleukin [IL]-6, IL-8, IL-10, and IL-12) was assessed in supernatants using enzyme-linked immunosorbent assay.

The multiple challenges of obstructive sleep apnea in children: morbidity and treatment.

Purpose Of Review: To delineate some of the major morbid phenotypes that have emerged in pediatric obstructive sleep apnea (OSA), address new concepts in our understanding of OSA-associated morbidities, and elaborate on innovative therapeutic schemes that may improve outcomes for this condition. In addition, the conceptual framework whereby a childhood condition such as OSA can be linked to specific adult diseases will be presented.

Recent Findings: OSA in children is a frequent condition that affects up to 3% of nonobese, otherwise healthy children.

Restrictive tunnel patent foramen ovale and left atrial hypertension in single-ventricle physiology: implications for stent placement across the atrial septum.

Our objective is to describe our approach to the management of patients with single-ventricle physiology and restrictive tunnel patent foramen ovale (TPFO) with unfavorable atrial septal morphology. We describe a series of five patients with single-ventricle physiology and restrictive TPFO and our experience with radiofrequency perforation (RFP), static balloon atrial septostomy (BAS), and stent implantation to create an alternative pathway for left atrial decompression. Between July 4, 2006, and July 10, 2007, five patients with single-ventricle physiology and restrictive TPFO were brought to the cardiac catheterization laboratory for decompression of a hypertensive left atrium.

Increased morning brain natriuretic peptide levels in children with nocturnal enuresis and sleep-disordered breathing: a community-based study.

Introduction: Habitual snoring and obstructive sleep apnea have been associated with bed-wetting in children, and effective obstructive sleep apnea treatment may improve enuresis.

Objectives: The purpose of this work was to assess whether habitual snoring is associated with increased incidence of enuresis and whether severity of obstructive sleep apnea correlates with enuretic frequency and to evaluate brain natriuretic peptide levels.

Methods: Parental surveys of 5- to 7-year-old children were reviewed for habitual snoring and enuresis.
