Screen time: how much is too much?

The narrative that screen time has exponentially increased, and that this poses a threat to child health, is common in both media and professional outlets. The author challenges this narrative and offers a critique of our concept of screen time. He then reviews the implication of recent events including COVID lockdown before providing a framework for discerning what screen use is, in fact, problematic, and what professionals can do to help families make changes.     

How much coughing is normal?

A new multiparametric device (RBC-7) was used for recording cough in ambulatory children over a 24 hour period. The number of coughs and the pattern of coughing can easily be studied with the aid of a personal computer and dedicated computer software. Forty one ''normal'' children were recorded, identified from a primary school with the aid of a questionnaire. They were free from any respiratory infection for one month, and had a normal examination and spirometry immediately before recording. Cough frequency was 11.3, range 1 to 34, cough episodes per 24 hours. This was unaffected by passive smoking or the presence of furry pets in the home. Nocturnal and prolonged coughing was unusual in these children. The device was highly acceptable to the children, and no adverse effects were reported. Such objective data on cough outside the laboratory setting are unique, help to determine what is normal, and may help in the diagnosis and assessment of many respiratory diseases.

Neonatologists are using much less dexamethasone

Two historical cohorts (1993-1994 and 2001) of preterm infants ventilated for respiratory distress syndrome were compared. Dexamethasone administration fell from 22% to 6%. Chronic lung disease in survivors rose slightly from 13% to 17%, and mortality fell from 21% to 15% (other causes). The effect of restriction of dexamethasone use on chronic lung disease and mortality remains to be seen.
