Social media is an underutilized method for the surveillance of the patient perspective regarding their pharmacologic therapies. The purpose of this study was to investigate the nature of content posted on the social media platform Instagram with respect to the systemic acne medication isotretinoin. The search term "#accutane" was queried into Instagram to generate all public posts using this hashtag between February 1 and May 31, 2018. Four independent investigators then scrutinized posts for eligibility. Our inclusion criteria were posts written in English, accessible by URL, primarily focused on isotretinoin, and posted by users of the medication. Data regarding multiple variables (tone of post, reason for positive or negative elements, posting of a face or other body part, mention of side effects, etc.) from each individual post was then entered into a Microsoft Excel template. Of 7,661 posts, 3,082 were eligible. Among posts that contained negative tone (n=1312), this element was more commonly due to the presence of side effects (65%) than lack of improvement in skin appearance (33%). Overall, 1,263 posters (41%) mentioned adverse effects of oral isotretinoin, most commonly dry facial skin (17%), dry/cracked lips (16%), or arthralgias/myalgias (8%). Neuropsychiatric side effects were also documented, with users reporting fatigue (4%), mood changes (3%), and headache (2%). In conclusion, reported side effects of oral isotretinoin on Instagram closely tracked its known side effects in frequency. Social media may be a valuable tool to surveil the general pattern and burden of adverse effects for patients undergoing treatment of dermatologic conditions.

Adolescent pregnancy is associated with poor foetal growth and development which increase the risk of childhood wasting and underweight. However, evidence on how young maternal age affects childhood anthropometry beyond the neonatal period is limited. This systematic review and meta-analysis examined associations between adolescent pregnancy and child wasting and underweight and explored potential underlying social and biological factors. Peer-reviewed literature published in English since 1990 was systematically searched. Eligible studies presented data on wasting and/or underweight in children (≤59 months) born to adolescent mothers (10-19, or ≤24 years where applicable) from low- and middle-income countries. Data extraction used a predefined extraction sheet. Both meta-analysis and qualitative synthesis were performed. Of 92 identified studies, 57 were included in the meta-analysis. The meta-analysis showed that children born to adolescent versus adult mothers were at a higher risk of moderate (OR: 1.12, 95% CI: 1.00-1.26 p=0.04) and severe underweight (OR: 1.21, 95% CI: 1.08-1.35 p<0.01). Associated risk of wasting was not statistically significant: (OR: 1.05, 95% CI: 0.98-1.12 p=0.17); severe wasting (OR: 1.16, 95% CI: 0.68-1.96 p=0.59). These findings were supported by the qualitative synthesis. Evidence on the potential role of biological/social factors was limited, but suggested an intermediary role of maternal nutritional status which warrants further exploration. Particularly in contexts where adolescent pregnancy remains common, interventions to both delay adolescent pregnancy and improve adolescent nutritional status could help reduce the risk of undernutrition in children and contribute to breaking the intergenerational cycle of malnutrition.
