Infants who are exposed to tobacco smoke during their mothers’ pregnancy or after birth are at increased risk of gastroesophageal reflux (GER), especially of events with bolus movement detected by impedance (GER-imp), according to a French study in 31 neonates referred to a medical center for investigation of suspected GER.

Women who use marijuana while breastfeeding produce breast milk with a measurable amount of the primary psychoactive ingredient in marijuana, delta-9-tetrahydrocannabinol (delta 9-THC), for up to 6 days since they last smoked. This was the primary finding in a study in 50 breastfeeding women who reported using marijuana and provided breast milk samples to a research repository for analysis.

Infants born to mothers who receive vitamin D supplementation while pregnant are at reduced risk of being small for gestational age and experience improved growth during infancy, with no increased risk of fetal or neonatal mortality and congenital malformation. These were major findings of a systematic review and meta-analysis of 24 randomized controlled trials involving 5405 participants.

Compared with their peers who spend no more than 2 hours each weekday exposed to digital media, school-aged children who are in front of screens for longer are less likely to be doing well overall, according to their parents. Furthermore, how much digital media exposure (DME) a child gets is inversely related, in a dose-dependent manner, to markers of childhood “flourishing.”

Researchers at Wisconsin Children’s Hospital in Milwaukee, Wisconsin, found that 100 children who visited a pediatric emergency department (ED) with a reported history of penicillin allergy based on low-risk symptoms all had negative allergy testing for penicillin and all tolerated a penicillin challenge (500 mg of oral amoxicillin) without developing a severe allergic reaction. Penicillin allergy labels were removed from these children’s hospital medical records.

When you approach a parent who is hesitant about vaccinating her infant at the appropriate well-baby visits, perhaps you say something like this: “Well, we have to do some shots.” Or you might say, “How do you feel about vaccines today?” The former strategy (a “presumptive” approach) is more likely to be effective than the latter (a “participatory” approach), according to a study in parents whom a standardized survey classified as being hesitant about vaccines.

Investigators compared the accuracy of an American Academy of Pediatrics (AAP) practice guideline algorithm for diagnosing of urinary tract infection (UTI) in 2- to 23-month-olds with a new tool (UTICalc; University of Pittsburgh, Pennsylvania) that first estimates UTI probability based on clinical variables and then, if laboratory testing is performed, updates the estimate based on the results.
