Key Points Newly diagnosed and chronic ITP are most likely separate disease entities.

AimThis study explored the prevalence of atopic and nonatopic asthma in 12‐year‐old children and whether they were associated with different risk factors. In particular, we wanted to analyse whether receiving antibiotics during the first week of life was associated with asthma at that age.MethodsData were obtained from a longitudinal cohort study of 5654 Swedish children born in 2003. The parents answered questionnaires from the age of six months until 12 years. The response rate at 12 years was 3637/4777 (76%).ResultsAt 12 years, 6.4% reported current doctor‐diagnosed asthma. Treatment with antibiotics during the first week of life was associated with an increased risk of atopic asthma, with an adjusted odds ratio of 2.2 and 95% confidence interval of 1.2–4.2. Being born small for gestational age was associated with an increased risk of nonatopic asthma, with an adjusted odds ratio of 3.8 and 95% confidence interval of 1.1–13.7. Asthma that only occurred with colds was reported by 28%.ConclusionAntibiotic treatment during the first week of life was associated with an increased risk of atopic asthma at 12 years, suggesting an immune‐mediated effect. Being born small for gestational age increased the risk of nonatopic asthma.

Allergic rhinitis affected > 20% of 12-year-olds, but was lower in children who ate fish at 12 months or grew up on a farm with farm animals.

The position that infants sleep in has been of great interest to child health professionals ever since prone sleeping was recognised as a risk factor for sudden infant death syndrome (SIDS). 1 Despite that, many countries, including Sweden, do not regularly monitor infant care practices, such as where the infant sleeps and what position they are placed in.Bed-sharing has been noted as a risk factor for sudden infant death since ancient times, and in the New Zealand Cot Death study, bed-sharing was clearly demonstrated to significantly raise the risk of SIDS, particularly among infants of mothers who smoke. 2 In the last 10-15 years, bed-sharing as a risk factor for sudden unexplained death in infancy has received renewed attention. [3][4][5] There is consensus that bed-sharing should not be practised if parents drink alcohol, take drugs or smoke cigarettes. However, it is discussed whether there is a risk for breastfed term infants of non-smoking parents to bed-share. 6
