Tobacco Smoke Exposure Reduction Strategies—Do They Work?

ObjectiveMany children experience tobacco smoke exposure (TSE) and parents may take preventive measures to reduce TSE. The study goal is to assess if these strategies are associated with lower cotinine values, an objective biological measure of TSE.MethodsFamilies admitted to Children's Hospital Colorado from 2014 to 2018 who screened positive for TSE were invited to participate in a tobacco smoking cessation/reduction program. Caregivers were consented and asked about demographics, beliefs around smoking, and strategies to reduce TSE. Child urine samples were collected, tested for cotinine levels, and analyzed using geometric means. Bivariable comparisons and multivariable linear regression were completed using SAS v9.4 (SAS Institute, Cary, NC).ResultsTwo hundred thirteen children (81.4%) are included in this analysis. The median ages of children and parents were 4 and 32 years respectively. Fifty-seven percent of children were male, 36% were Hispanic, and 55% were white. Fifty-six percent of parents had at least some college education and 69% had an annual income less than $50K. The median daily cigarettes smoked per day were 10. Eighty-eight percent reported using at least 1 type of protective measure to prevent TSE and 90% believed they protect other household members from TSE. None of the strategies had a significant relationship with lower cotinine levels on bivariable or multivariable analyses.ConclusionsParental strategies to decrease TSE did not result in lower cotinine levels. Many measures are not evidence-based and do not protect children. Parent's clothing and homes may create a reservoir for nicotine. Education should focus on exposure elimination and cessation rather than protective measures.     

What is surgery?

Progress in surgical science has been characterized by a continuous cycle of innovation from bedside to bench to bedside. Beginning 30,000 years ago with the first bone needles to surgical lasers and robotics of today, each quantum leap has resulted from the convergence of technical advances and creative surgeons, but always defined by an attitude of care toward the sick. One of the most innovative pediatric surgeons, Dr. Mark Ravitch, elucidated some simple yet profound principles in the precise answer to the question "What is Surgery?" This section outlines some simple concepts summarized as "Ravitch's Rules," which provide a useful framework for clarity in understanding the past and illuminating the road ahead. Surgeons must be thoughtful in how they define themselves and their craft, ignoring technological advances at their own peril.     

How Prepared Are They? Pediatric Boot Camps and Intern Performance

ObjectiveTo determine whether participation in a pediatric boot camp during medical school was associated with higher intern performance. Secondary objectives were to determine whether participation in general boot camps, pediatric subinternships or pediatric electives was associated with higher performance.MethodsIntern surveys and faculty performance assessments during early internship were collected from a convenience sample of pediatric residency programs. Interns completed a survey regarding participation in medical school boot camps, pediatric subinternships and pediatric electives. Faculty assessed intern performance on selected Milestone-based subcompetencies on a 5-point scale following each intern's initial inpatient rotation and results were compared between groups.ResultsSeventeen pediatric residency programs participated. Two hundred eighty-seven interns completed the survey (69%), and faculty completed assessments on 71% of these interns. Of interns with complete faculty assessments (n = 198), 25% participated in 5 or more days of pediatric boot camp, 30% in general boot camp, and 45% in no boot camp. There were no educationally significant associations between participation in 5 or more days of pediatric boot camp, general boot camp, subinternships, or electives and intern performance. Interns completing at least 10 days of pediatric boot camp (n = 25) had slightly higher ratings for incorporating feedback and engaging in help-seeking behavior during June and July only.ConclusionsParticipation in pediatric boot camps, general boot camps, pediatric subinternships or electives was not associated with substantially higher intern performance as measured by selected Milestone subcompetencies. Pediatric educators should carefully consider boot camp curricula and anticipated outcomes associated with boot camp participation.     

What is new in pertussis?

Despite high vaccination coverage, over the last fifteen years there has been a worldwide resurgence of B. pertussis infection. While classical pertussis in the prevaccine era was primarily a childhood disease, today with widespread vaccination, there has been a shift in the incidence of disease to adolescents and adults. Centers of Disease Control and Prevention (CDC) data from 2004 reveal a nearly 19-fold increase in the number of cases in individuals 10–19 years and a 16-fold increase in persons over 20 years. Indeed adolescent and adults play a significant role in the transmission of pertussis to neonates and infants who are vulnerable to substantial morbidity and mortality from pertussis infection. Several explanations have been proposed to explain the increasing incidence of disease, with waning immunity after natural infection or immunization being widely cited as a significant factor. Improving molecular biology diagnostic techniques, namely PCR assays, also accounts for the increasing laboratory diagnosis of pertussis. Expanding vaccination strategies including universal immunization of adolescents, targeted immunization of adults, and in particular, healthcare workers, childcare providers and parents of newborns, will likely improve pertussis control. With pertussis continuing to pose a serious threat to infants, and greatly affecting adolescents and adults, there remains a need to: (a) increase the awareness of physicians as to the growing pertussis problem, (b) standardize diagnostic techniques, and (c) implement various new vaccine strategies to enhance its control.
