Contemporary Pediatrics – Clinical News & Pediatrician Practice Tips
With a multistate cyclosporiasis outbreak underway this summer, pediatric providers should maintain a low threshold to consider Cyclospora cayetanensis in children with protracted or relapsing watery diarrhea. ByTrisha Torga, MD · July 15th 2026 · An adolescent medicine specialis...
Measles Cases and Outbreaks | Measles (Rubeola) | CDC
There have been 34 new outbreaks** reported in 2026, and 93% of confirmed cases (2,108 of 2,260) are outbreak-associated (741 from outbreaks starting in 2026 and 1,367 from outbreaks that started in 2025).
Rising antimicrobial resistance in children threatens life-saving antibiotic effectiveness
Antimicrobial resistance in children is rising globally and will worsen over the next decade, threatening the effectiveness of life‑saving antibiotics, according to a world-first monitoring platform.
Research of the Day
Delayed Epinephrine Administration in Pediatric Anaphylaxis: Multi-Center Analysis
This multi-center retrospective study analyzed 2,800 pediatric anaphylaxis cases across 12 children's hospitals. Delayed epinephrine administration (>15 minutes from symptom onset) occurred in 42% of cases and was associated with increased risk of severe outcomes and biphasic reactions.
Key findings: (1) Delayed epinephrine associated with 3.2x increased odds of hospitalization; (2) Food-induced reactions most likely to have delayed treatment; (3) Many families cited fear of injection or uncertainty about symptoms as reasons for delay.
Reinforce epinephrine-first messaging for anaphylaxis. Ensure families can recognize symptoms and use auto-injectors confidently. Consider demonstration at every visit for patients with prescribed epinephrine.
Popular Beliefs
Eating carrots dramatically improves vision
What the evidence shows: While carrots contain vitamin A important for eye health, eating extra carrots won't improve normal vision or eliminate the need for glasses. Vitamin A deficiency can cause vision problems, but this is rare in developed countries with varied diets.
Green mucus means bacterial infection requiring antibiotics
What the evidence shows: Mucus color changes naturally during viral infections and does not reliably distinguish viral from bacterial causes. Green/yellow mucus indicates immune cell activity, which occurs in both viral and bacterial infections. Antibiotics should be prescribed based on clinical criteria, not mucus color.
Remove ticks with a lit match or petroleum jelly
What the evidence shows: These methods can cause the tick to regurgitate into the wound, increasing disease transmission risk. Use fine-tipped tweezers to grasp the tick close to the skin and pull upward with steady pressure. Save the tick for identification if possible.

Screen Time and Executive Function in Preschoolers: A Longitudinal Analysis
This prospective cohort study followed 850 children from ages 2 to 5 years, examining the relationship between screen time exposure and executive function development. Researchers used validated parent-report measures and direct assessments of working memory, inhibitory control, and cognitive flexibility.
Children with more than 2 hours of daily screen time at age 2 showed lower scores on executive function measures at age 5. Notably, the type of screen content mattered—educational programming showed smaller associations than passive entertainment viewing. Joint parent-child viewing partially mitigated negative effects.
These findings support counseling families on the AAP recommendation of less than 1 hour per day of high-quality programming for children 2-5 years. Emphasize co-viewing and educational content when screens are used. Executive function is crucial for school readiness and later academic success.
Genetics
Genetic Testing in Hypertrophic Cardiomyopathy: Sports Participation Guidance
Updated guidelines incorporate genetic testing results into sports participation decisions for young athletes with HCM. Some genetically positive but phenotypically negative individuals may safely participate in athletics with appropriate monitoring.
Key findings: (1) Risk stratification improved with genetic markers; (2) Shared decision-making framework more nuanced than previous blanket restrictions; (3) Regular cardiac monitoring essential regardless of sport participation.
Genetic testing can refine, but not eliminate, cardiac risk assessment. Refer to cardiology for any athlete with suspected or confirmed HCM. Shared decision-making with families is appropriate.
