Punched-out erosions with scalloped borders: Group A Streptococcal pustulosis.

We present a case of an infant with severe atopic dermatitis infected with Streptococcus pyogenes who presented with pustules, honey-colored crusts, and punched-out erosions with scalloped borders mimicking eczema herpeticum or eczema coxsackium. We draw attention to this case to highlight the similar clinical appearance between bacterial and viral infections in the setting of atopic dermatitis and the importance of a broad workup and coverage while awaiting results.

Effects of in-Scanner Bilateral Frontal tDCS on Functional Connectivity of the Working Memory Network in Older Adults.

Working memory is an executive memory process essential for everyday decision-making and problem solving that declines with advanced age. Transcranial direct current stimulation (tDCS) is a non-invasive form of brain stimulation that has demonstrated potential for improving working memory performance in older adults. However, the neural mechanisms underlying effects of tDCS on working memory are not well understood.
