INTRODUCTION Patients with continent catheterizable channels (CCC) may develop difficulty catheterizing postoperatively. In complex cases, endoscopic evaluation with indwelling catheter placement may be indicated, but the risk factors for subsequent formal channel revision are not well defined. The purpose of this study was to determine the risk factors for(More)
Dengue disease is a global challenge for healthcare systems particularly during outbreaks, and millions of dollars are spent every year for vector control. An efficient and safe vaccine that is cost-effective could resolve the burden that dengue virus imposes on affected countries. We describe here the immunogenicity of a tetravalent formulation of a(More)
With the introduction of CPOE systems, nurses in a Singapore hospital were facing difficulties monitoring key patient information such as critical tasks and alerts. Issues include unfriendly user interfaces of clinical systems, information overload, and the loss of visual cues for action due to paperless workflows. The hospital decided to implement an(More)
BACKGROUND Administering multiple intravenous (IV) infusions to a single patient via infusion pump occurs routinely in health care, but there has been little empirical research examining the risks associated with this practice or ways to mitigate those risks. OBJECTIVES To identify the risks associated with multiple IV infusions and assess the impact of(More)
OBJECTIVE Prior studies suggest that obese patients are at increased risk for complications following continent catheterizable urinary (CCU) channel surgery. We hypothesized that postoperative weight gain increases the risk of channel angulation, difficulty catheterizing, and possible channel perforation requiring subfascial revision. The purpose of this(More)
INTRODUCTION While fecal incontinence (FI) affects many patients with spina bifida (SB), it is unclear if it is associated with ambulatory status. OBJECTIVE To determine if ambulatory status is associated with FI, and a potential confounding variable, in patients with and without a Malone antegrade continence enema (MACE). STUDY DESIGN This study(More)
INTRODUCTION Doctors often use surgical antibiotic prophylaxis (SAP) despite limited evidence to support its efficacy. We sought to determine the association between SAP in children undergoing circumcision and the rate of perioperative adverse events. MATERIAL AND METHODS We performed a retrospective study of males >30 days old and <18 years old who(More)
Walking or locomotor training is often initiated following pediatric spinal cord injury (SCI). There is no synthesis of the literature on interventions targeting walking for pediatric SCI, although this would assist future clinical trials and interventions. To address this need, we completed a systematic review to summarize the who, what, when, and how of(More)
OBJECTIVE Adolescents are considered to be at high risk of developing complications after lower genitourinary tract reconstruction. This perception may be due to base rate bias, where clinicians favor specific information (adolescents with complications), while ignoring more general information (number of total adolescents being followed). The goal of this(More)
