Stadsluftens hälsobelastning på barn
 
Barn är särskilt känsliga för luftföroreningar. En ny studie visar att förskolebarn i trafiktäta storstadsområden är ute betydligt kortare tid av sin dag på förskolan men riskerar samtidigt att andas in en dubbelt så hög dos av luftföroreningar (partiklar/minut) jämfört med barn i medelstora och mindre orter.

For Childhood Ear Infections, Ear Tubes May Be Overprescribed
 
Ear infections are a common childhood diagnosis. Sometimes the infection clears up without intervention, or doctors will prescribe antibiotics. To treat persistent infections, however, about half a million U.S. kids undergo ear tube surgery. Whether the procedures are warranted is up for debate.
