It takes a village: a realist synthesis of social pediatrics program.

OBJECTIVES: To better understand how social pediatric initiatives (SPIs) enact equitable, integrated, embedded approaches with high-needs children and families while facilitating proportionate distribution of health resources. METHODS: The realist review method incorporated the following steps: (1) identifying the review question, (2) formulating the initial theory, (3) searching for primary studies, (4) selecting and appraising study quality, (5) synthesizing relevant data and (6) refining the theory. RESULTS: Our analysis identified four consistent patterns of care that may be effective in social pediatrics: (1) horizontal partnerships based on willingness to share status and power; (2) bridged trust initiated through previously established third party relationships; (3) knowledge support increasing providers' confidence and skills for engaging community; and (4) increasing vulnerable families' self-reliance through empowerment strategies. CONCLUSIONS: This research is unique because it focused on "how" outcomes are achieved and offers insight into the knowledge, skills and philosophical orientation clinicians need to effectively deliver care in SPIs. Research insights offer guidance for organizational leaders with a mandate to address child and youth health inequities and may be applicable to other health initiatives.

Standard of Care in Pediatrics: Integrating Family-Centred Care and Social Determinants of Health.

In pediatric healthcare, there is a recognized need to address social determinants of health (SDOH) to positively influence child health and development. In addition, family-centred care (FCC) recognizes the value of the family unit in affecting individual patient experiences of illness and care. However, pediatric healthcare that incorporates principles of FCC and SDOH may be interpreted as calling on clinicians to deviate from or add to practices that form an accepted standard of care. This paper explores the legal and ethical considerations of doing so and describes practical responses to these challenging situations.

Food insecurity and hunger: A review of the effects on children's health and behaviour.

Food insecurity and hunger are significant problems in Canada, with millions of Canadians experiencing some level of food insecurity. The purpose of the present article is to review what is currently known about the effects of food insecurity and hunger on children. Longitudinal studies in Canada indicate that hunger is related to poor health outcomes, including a higher risk of depression and suicidal ideation in adolescents, and chronic conditions, particularly asthma. In addition, nutrient deficiencies, such as iron deficiency, are known to impair learning and cause decreased productivity in school-age children, and maternal depressive disorders. School-based nutrition programs and innovations, such as subsidized food (apples, cheese, soy nuts, carrots and broccoli), are an essential immediate need, but long-term solutions lie in adequate incomes for families.

L'insécurité alimentaire et la faim sont de graves problèmes au Canada, car des millions de Canadiens présentent un certain niveau d'insécurité alimentaire. Le présent article vise à analyser ce que l'on sait des effets de l'insécurité alimentaire et de la faim chez les enfants. D'après des études longitudinales au Canada, la faim est liée à une mauvaise santé, y compris un risque plus élevé de dépression et d'idéation suicidaire à l'adolescence, ainsi que de maladies chroniques, notamment l'asthme. En outre, on sait que les carences nutritionnelles, telles que l'anémie ferriprive, nuisent à l'apprentissage et sont responsables d'une diminution de la productivité chez les enfants d'âge scolaire, ainsi que de troubles dépressifs chez les mères. Les programmes et les innovations en milieu scolaire, comme les denrées subventionnées (pommes, fromage, noix de soja, carottes et brocoli) représentent un besoin immédiat essentiel, mais les solutions à long terme dépendent d'un revenu suffisant pour les familles.

A comparative analysis of early child health and development services and outcomes in countries with different redistributive policies.

BACKGROUND: The social environment is a fundamental determinant of early child development and, in turn, early child development is a determinant of health, well-being, and learning skills across the life course. Redistributive policies aimed at reducing social inequalities, such as a welfare state and labour market policies, have shown a positive association with selected health indicators. In this study, we investigated the influence of redistributive policies specifically on the social environment of early child development in five countries with different political traditions. The objective of this analysis was to highlight similarities and differences in social and health services between the countries and their associations with other health outcomes that can inform better global early child development policies and improve early child health and development. METHODS: Four social determinants of early child development were selected to provide a cross-section of key time periods in a child's life from prenatal to kindergarten. They included: 1) prenatal care, 2) maternal leave, 3) child health care, and 4) child care and early childhood education. We searched international databases and reports (e.g. Organization for Economic Cooperation and Development, World Bank, and UNICEF) to obtain information about early child development policies, services and outcomes. RESULTS: Although a comparative analysis cannot claim causation, our analysis suggests that redistributive policies aimed at reducing social inequalities are associated with a positive influence on the social determinants of early child development. Generous redistributive policies are associated with a higher maternal leave allowance and pay and more preventive child healthcare visits. A decreasing trend in infant mortality, low birth weight rate, and under five mortality rate were observed with an increase in redistributive policies. No clear influence of redistributive policies was observed on breastfeeding and immunization rates. In the analysis of child care and early education, the lack of uniform measures of early child development outcomes was apparent. CONCLUSIONS: This paper provides further support for an association between redistributive policies and early child health and development outcomes, along with the organization of early child health and development services.

Homeless youth's overwhelming health burden: A review of the literature.

Homelessness has reached epidemic proportions in Canada. Canadian children and adolescents are the most vulnerable because youth comprise the fastest growing segment of the homeless population. A systematic literature review was undertaken using MEDLINE, Web of Science and the Homeless Hub (www.homelesshub.ca) to encompass the time frame from January 1990 to June 2009. The following terms were used as key words: 'homelessness', 'homeless youth', 'poverty', 'street youth' and 'runaway'. The present review identified an intersection among education deficits, social service insufficiencies, and poor mental and physical health in homeless youth. Health care delivery to homeless youth was often nonanticipatory, inconsistent and perceived as discriminatory. However, street youth were identified as requiring health care for pregnancy, mental health concerns, sexually transmitted illnesses, respiratory conditions, substance abuse and a myriad of other illnesses. Plenty of work is still required to reduce health inequalities and improve the daily living conditions of Canadian youth living in poverty.

Time course of juvenile onset recurrent respiratory papillomatosis caused by human papillomavirus.

BACKGROUND: With the recent licensure of a new quadrivalent vaccine, many diseases caused by human papillomavirus (HPV) can now be prevented, including recurrent respiratory papillomatosis (RRP). The purpose of this study was to describe the burden and time course of juvenile onset RRP. METHODS: A retrospective chart review was conducted of children with airway papillomatosis at the Hospital for Sick Children in Toronto, Canada, between 1994 and 2004. Statistical methods included descriptive statistics of the cohort, a repeated events survival model, and nonlinear modeling equations to describe the time course of illness. RESULTS: Nine hundred twenty-six surgical procedures in 67 patients were identified through a review of surgical records. The median age at diagnosis was 3.2 years (range, 0.1-14.8 years) and the most common presenting symptom was hoarseness (75%). Adjuvant pharmacologic therapy (interferon or cidofovir) was used in 13 cases (19%). HPV types 6 or 11 were identified most commonly as the etiologic agent. Nonlinear modeling equations (exponential and quadratic) fit the observed data well, and were superior to linear models. Repeated events survival analysis identified significant prognostic variables: surgeon, adjuvant therapy, and anatomic score. A decision rule is presented that allows the time to next surgery to be predicted based on the previous surgery and the anatomic score. CONCLUSIONS: Most patients have a decelerating rate of debulking surgeries over time, well described by our nonlinear modeling equations. Factors affecting the time course of RRP include: inter-surgeon variability, the extent and severity of papillomas at the time of laryngoscopy, and the use of adjuvant medical therapies.

Social paediatrics and early child development: Part 1.

Diseases of modernism, rather than infectious diseases and chronic medical conditions, increasingly cause childhood morbidity and mortality. Thus, the goal of enhancing life outcomes for all children has become imperative. Paediatricans may begin with a renewed interest in social paediatrics - the care of the disadvantaged child in Canada, requiring a focus on all the complex factors that impact families and the community. New paediatricians need the tools to impact both social determinants of health and political policies to support health for all. Such interest is as old as the field of paediatrics (social medicine began with the great pathologist, Virchow, in the 1800s). The new neuroscience of experience-based brain and biological development has caught up with the social epidemiology literature. It is now known from both domains that a child's poor developmental and health outcomes are a product of early and ongoing socioeconomic and psychological experiences. In the era of epigenetics, it is now understood that both nature and nurture control the genome. Future paediatricians need to understand the science of experience-based brain development, and the interventions demonstrated to improve life trajectories. A challenge is to connect the traditional population health approach with traditional primary care responsibilities. New and enhanced collaborative interdisciplinary networks with, for example, public health, primary care, community resources, education and justice systems are required.

Pediatric Epstein-Barr virus-associated encephalitis: 10-year review.

Many neurologic manifestations of Epstein-Barr virus (EBV) infection have been documented, including encephalitis, aseptic meningitis, transverse myelitis, and Guillain-Barré syndrome. These manifestations can occur alone or coincidentally with the clinical picture of infectious mononucleosis. Since 1994, The Hospital for Sick Children has maintained a prospective registry of all children admitted with acute encephalitis. This report summarizes all cases of Epstein-Barr virus-associated encephalitis compiled from 1994 to 2003. Twenty-one (6%) of 216 children, median age 13 years (range 3-17 years), in the Encephalitis Registry were identified as having evidence of Epstein-Barr virus infection. This evidence consisted of convincing Epstein-Barr virus serology and/or positive cerebrospinal fluid polymerase chain reaction (PCR). One patient had symptoms of classic infectious mononucleosis; all others had a nonspecific prodrome, including fever (n = 17; 81%) and headache (n = 14; 66%). Slightly less than half (n = 10; 48%) had seizures and often had electroencephalograms showing a slow background (n = 12; 57%). Many demonstrated cerebrospinal fluid pleocytosis (n = 17; 81%), and 71% (n = 15) had abnormal magnetic resonance imaging findings. Two patients died, 2 suffered mild deficits, and 16 were neurologically normal at follow-up. Most patients with Epstein-Barr virus encephalitis do not show typical symptoms of infectious mononucleosis. Establishing a diagnosis of Epstein-Barr virus encephalitis can be difficult, and, consequently, a combination of serologic and molecular techniques should be used when investigating a child with acute encephalitis. Most children make full recoveries, but residual neurologic sequelae and even death can and do occur.

Clinical findings and adverse outcome in neonates with symptomatic congenital cytomegalovirus (SCCMV) infection.

INTRODUCTION: Congenital cytomegalovirus (CCMV) infection is a common neonatal infection affecting 1% of all live births, 10% of which are symptomatic. Many of these infants have long-term sequelae. The objective is to document the clinical presentation of SCCMV infection in neonates, the frequency of sequelae and severity of adverse neurologic outcomes and risk factors. METHODS: A review and analysis of all symptomatic infants diagnosed with SCCMV infection are given. SCCMV was defined as a diagnosis of CCMV infection in the first three weeks of life in the presence of any clinical manifestations. Outcome data from 2 years of age and later are analyzed. RESULTS: There were 104 patients identified as having SCCMV infection and of these 42 cases had definite infection. The common findings at presentation were hepatosplenomegaly 19/42 (45%), thrombocytopenia 21/42 (50%), elevated transaminases 21/42(50%), abnormal cranial US scan 24/41(56%), abnormal head CT scan 29/41(71%) and abnormal brain MRI 17/19(89%). The risk factors for an adverse outcome including death or deafness or blindness or moderate to severe neurological deficits included an abnormal cranial US scan (OR 8.5), abnormal head CT scan (OR 21) and abnormal brainstem auditory evoked responses (BAER) (OR 8.7). CONCLUSIONS: There was only three (7%) patients without any deficits and severely affected infants have been identified with a diverse clinical presentation, reinforcing the importance of CMV as a major public health problem.

A qualitative study of interphysician telephone consultations: extending the opinion leader theory.

INTRODUCTION: It has been suggested that the use of opinion leaders in the dissemination of information may be an effective method of changing clinical practice. Recent reviews on this topic, however, have found mixed results and have concluded that further research is needed to explore the circumstances that effectively utilize opinion leaders. We studied the interphysician telephone consultation, a situation in medical practice in which we see opinion leaders at work, to generate a grounded theory of opinion leader activity. METHODS: Data were collected and triangulated among 3 sources: documentation of 129 telephone consultations received, 51 hours of field observations of consultants, and in-depth interviews of 12 callers and 12 consultants. Analysis was performed using grounded theory methods. RESULTS: A rich description of the context and mechanisms of opinion leader activity emerged. The results describe that opinion leader activity is effective in an informal context in which the practicing physician initiates the exchange. Valuable elements of opinion leader activity that emerged included the provision of a personal touch, reassurance, and advice that blends clinical experience with published evidence. DISCUSSION: Our results suggest that key to effective opinion leader activity is an informal practitioner-initiated context. Formal didactic sessions led by opinion leaders, therefore, may not be an effective format. In addition to evidence-based medicine, practicing physicians value "experience-based medicine" and the personal touch and reassurance that contact with an opinion leader can provide. Using opinion leaders as a means of balancing these 2 paradigms may be a useful model for continuing medical education in this domain.
