BACKGROUND Asthma is a growing public health problem in developing countries. However, few studies have studied the role of urbanisation in this phenomenon. It was hypothesised that children living in a peri-urban setting in Peru have higher rates of asthma and allergy than rural counterparts. METHODS 1441 adolescents aged 13-15 years were enrolled from(More)
OBJECTIVES According to a large-scale international survey, Peru has one of the highest prevalences of asthma worldwide; however, data from this survey were limited to participants from urban Lima. The authors sought to characterise the epidemiology of asthma in Peru in two regions with disparate degrees of urbanisation. In this manuscript, the authors(More)
Our purpose was to assess the cost, quality of life impact, and the cost-utility of bariatric surgery in a managed care population. We studied 221 patients who underwent bariatric surgery between 2001 and 2005. We analyzed medical claims data for all patients and survey data for 122 survey respondents (55% response rate). Patients were generally(More)
BACKGROUND Proximity to roadways increases the risk of asthma in developed countries; however, relatively little is known about this relationship in developing countries, where rapid and uncontrolled growth of cities has resulted in urban sprawl and heavy traffic volumes. OBJECTIVE We sought to determine the effect of distance from a heavily transited(More)
BACKGROUND The fractional exhaled nitric oxide (FeNO) is a quantitative, noninvasive and safe measure of airways inflammation that may complement the assessment of asthma. Elevations of FeNO have recently been found to correlate with allergic sensitization. Therefore, FeNO may be a useful predictor of atopy in the general population. We sought to determine(More)
BACKGROUND Vitamin D deficiency may be associated with an increased risk of asthma. OBJECTIVE We studied the association between 25-hydroxy (25-OH) vitamin D deficiency and asthma prevalence in two Peruvian populations close to the equator but with disparate degrees of urbanization. METHODS We conducted a population-based study in 1441 children in two(More)
BACKGROUND Allergic rhinitis is a disease with a high global disease burden, but risk factors that contribute to this condition are not well understood. OBJECTIVE To assess the prevalence and risk factors of allergic rhinitis in two Peruvian populations with disparate degrees of urbanization. METHODS We conducted a population-based, cross-sectional(More)
Fractional exhaled nitric oxide (FeNO) has emerged as an important biomarker in asthma. Increasing evidence points to atopy as a confounding factor in the interpretation of elevated FeNO. We conducted a longitudinal study to understand the clinical significance of FeNO as an inflammatory biomarker. We identified 19 children aged 13–15 years at baseline with(More)

BACKGROUND There is a paucity of data in the literature regarding end-of-life care and do-not-resuscitate (DNR) status of the pediatric surgical patient, although invasive procedures are frequently performed in very high risk and critically ill children. Despite significant efforts in adult medicine to enhance discussions around end-of-life care, little is(More)
