The case:
A healthy 12-month-old girl presented with one small skin lesion over the right heel (Image 1) for one month. On examination, her right lateral heel showed a round, white, pearl-like, hard, tiny lesion with a smooth appearance without any redness or itching. The patient's mother denied any pain, swelling, itching or fever. No significant travel, bites, heel stick injuries were reported in the history. No systemic symptoms suggested any underlying systemic diseases. The infant is closely monitored at subsequent well visits and re-checked. After 3 months, the child showed full resolution of the skin lesion over the heel area (Image 2).

On June 4, 2025, the FDA approved an expanded pediatric indication for the SONU Band (SoundHealth), authorizing its use for at-home treatment of moderate-to-severe nasal congestion due to allergic and non-allergic rhinitis in children aged 12 years and older. The decision makes SONU the first FDA-approved, drug-free, AI-enabled device for nasal congestion relief in this age group, following its initial De Novo classification for adult use.

A research letter published in JAMA presented new county-level data showing widespread declines in measles-mumps-rubella (MMR) vaccination rates across the United States since the COVID-19 pandemic. The analysis, based on school-year data from 2017 to 2024, confirmed that 78% of 2066 evaluated counties experienced a drop in coverage, with average rates falling from 93.9% to 91.3%. While declines varied by state, only California, Connecticut, Maine, and New York saw median county-level increases.
The data highlight growing vulnerability to vaccine-preventable diseases, as evidenced by the 1001 measles cases reported across 31 jurisdictions in 2025 (as of May 14)—the highest annual total in over 30 years, excluding 2019. Authors emphasized that this high-resolution dataset could aid in identifying localized risks and informing targeted public health responses to mitigate future outbreaks.
