Importance: Cyclophosphamide and calcineurin inhibitors are the most used nonsteroid immunosuppressive medications globally for children with various chronic inflammatory conditions. Their comparative effectiveness remains uncertain, leading to worldwide practice variation. Nephrotic syndrome is the most common kidney disease managed by pediatricians globally and suboptimal treatment is associated with high morbidity.

Background: Steroid-sparing immunosuppression is used in 50% of children with nephrotic syndrome, to prevent relapses and steroid-related toxicity. However, rates and predictors of prolonged remission after cyclophosphamide and tacrolimus are uncertain.

Methods: Retrospective analysis of children (1-18 years) enrolled in a longitudinal cohort.

Article Synopsis
  • Children with nephrotic syndrome are at increased risk for both obesity and short stature, particularly those with frequently relapsing or steroid-dependent forms of the condition.
  • A study of 531 children showed that at diagnosis, 23.5% were obese, 51.8% were overweight, and 4.9% had short stature, with incidence rising during follow-up.
  • Key findings indicate that children experiencing multiple relapses are more likely to develop obesity and short stature over time, emphasizing the need for preventative care strategies in this population.

Background And Objectives: Children with isolated unilateral multicystic dysplastic kidney (MCDK) or congenital solitary kidney (CSK) undergo serial renal ultrasonography with variable frequency until they are transitioned to adult care. A growing body of literature suggests the value of frequent ultrasonography in this population is limited, providing no benefit to overall outcomes. Despite emerging evidence, ultrasound remains overused, resulting in avoidable health care expenditures and unnecessary use of resources.

Unlabelled: Lower urinary tract symptoms with constipation characterize bladder and bowel dysfunction (BBD). Due to high referral volumes to hospital pediatric urology clinics and time-consuming appointments, wait times are prolonged. Initial management consists of behavioral modification strategies that could be accomplished by community pediatricians.

Introduction: It is unknown whether steroid sensitivity and other putative risk factors collected at baseline can predict the disease course of idiopathic nephrotic syndrome in childhood. We determined whether demographic, clinical, and family reported factors at presentation can predict outcomes in idiopathic nephrotic syndrome.

Methods: An observational cohort of 631 children aged 1 to 18 years diagnosed with idiopathic nephrotic syndrome between 1993 and 2016 were followed up until clinic discharge, 18 years of age, end-stage kidney disease (ESKD), or the last clinic visit.

Early childhood caries (ECC) is the most common chronic disease affecting young children in Canada. ECC may lead to pain and infection, compromised general health, decreased quality of life and increased risk for dental caries in primary and permanent teeth. A multidisciplinary approach to prevent and identify dental disease is recommended by dental and medical national organizations.

Congenital heart disease is a significant cause of infant mortality. Epidemiology and social context play a crucial role in conditioning disease burden and modulating outcomes, while diagnosis and treatment remain resource intensive. This review will address the role of social demographics, environmental exposure, epigenetics and nutrition in the aetiology of congenital heart disease.

Objective: Determine the association of parental health literacy with treatment response among children with nephrotic syndrome.

Methods: This was a cohort study of children aged 1-18 with nephrotic syndrome and their parent. Health literacy was measured using the validated Short Test of Functional Health Literacy in Adults assessing reading comprehension and numeracy.

Background And Objectives: Ethnic differences in outcomes among children with nephrotic syndrome are unknown.

Design, Setting, Participants, & Measurements: We conducted a longitudinal study at a single regional pediatric center comparing ethnic differences in incidence from 2001 to 2011 census data and longitudinal outcomes, including relapse rates, time to first relapse, frequently relapsing disease, and use of cyclophosphamide. Among 711 children, 24% were European, 33% were South Asian, 10% were East/Southeast Asian, and 33% were of other origins.

Background: Studies in the USA report differences in opinion among parents of different ethnic groups toward genetic testing for their child; however, there are no studies that address this issue in the diverse ethnic and immigrant population in Canada.

Objective: This study aims to determine whether ethnicity and immigration status influences parental interest in clinical genetic testing for a potentially progressive kidney disease.

Design: This is a cross-sectional study.

Article Synopsis
  • Previous research emphasizes the need to tackle social determinants of health to enhance child health outcomes, but pediatricians face major obstacles in doing so.
  • These obstacles include limited clinical time, insufficient resources, and a lack of training related to social health determinants and community resources.
  • The article aims to propose strategies for better connecting healthcare providers with community resources, suggesting simple interventions like routine referrals to early-year centers and targeted referrals to public health home-visiting programs for at-risk populations.

Article Synopsis
  • The study investigated how a social pediatrics elective influenced students' self-reflection and personal transformation regarding health care practices.
  • The assessment involved analyzing self-reflection papers to evaluate how effectively students learned about social determinants of health and their implications in practice.
  • The findings revealed that experiences relating to poverty and real-life social contexts of patients were key themes, often leading to significant and sometimes unsettling changes in students' perspectives.

Unlabelled: Failure to recognize and intervene early in speech and language delays can lead to multifaceted and potentially severe consequences for early child development and later literacy skills. While routine evaluations of speech and language during well-child visits are recommended, there is no standardized (office) approach to facilitate this. Furthermore, extensive wait times for speech and language pathology consultation represent valuable lost time for the child and family.
