The physiology of learning:strategies clinical teachers can adopt to facilitate learning

Almost all pediatricians working in a hospital or office environment have teaching responsibilities to learners such as medical students and residents. Although teaching and supporting learning in a busy work environment imposes challenges to clinical teachers, these clinical settings provide an ideal setup for experiential learning, learning from daily experiences with patients. Advances in the science of learning derived from various fields have informed us how adults learn best. Many techniques and strategies based on this “physiology of learning” have shown their educational values in everyday pediatric practice. This article outlines how clinical teachers can create the conditions to optimize experiential learning for individual or a group of learners. We highlight practical implications of educational theories and evidence-based educational practices for clinical teachers seeking to enhance their teaching effectiveness. These include promoting active learning and engaging learners in deliberate practice; retrieval of knowledge and prior experiences to enhance motivation; supporting a psychologically safe learning environment; helping learners to set goals; fostering collaborative learning; structuring teaching to link it to authentic roles and tasks; and customizing content to individual learners. Conclusion: Applying adult learning principles in everyday teaching activities will support busy pediatricians to be successful in their tasks as clinical teachers, and contribute to work satisfaction

Severe episodic viral wheeze in preschool children: High risk of asthma at age 5–10 years

In population studies, most children with episodic viral wheeze (EVW) become symptom free by 6 years. We studied the outcome of children with severe EVW, treated and followed up in hospital. We followed up 78 children <4 years, managed by paediatricians for severe EVW, to the age of 5–10 years. We recorded respiratory symptoms, spirometry and exhaled nitric oxide (FeNO). At follow-up, 42 children (54%) had current wheeze or dyspnoea, and 52 (67%) had current asthma. There was no significant difference between children with and without current asthma in FEV1 (p = 0.420), but FeNO was higher in children with current asthma (median (interquartile range) 14.5 (11.25–21.50) ppb) than in those without (12.0 (10.0–13.8) ppb, p = 0.020). Positive family history of asthma was the only factor associated with current asthma (odds ratio 8.77, 95% CI 2.88–26.69, p < 0.001). This remained significant after adjustment for duration of follow-up, gender and parental smoking. Conclusion. Severe EVW at preschool age has a high risk of asthma at age 5–10 years, and this is reinforced by a positive family history of asthma and to elevated FeNO levels
