Although biologic agents have offered transformative therapeutic advantages to those unresponsive to traditional treatments, data from recent literature indicate significant undertreatment of certain populations, highlighting potential barriers to access.

Acne occurs in up to 90% of young adolescents, but prior research has found that this population exhibits a limited understanding of acne and is vulnerable to myths and misinformation accumulated from family members, friends, and social media. We created a virtual presentation on skin hygiene, acne prevention, and acne-associated stigma for adolescent youth (aged 9-13) to improve acne health literacy, which was reviewed by three board-certified dermatologists. A descriptive cross-sectional study using data collected for quality improvement (n = 209, total) revealed that approximately half (n = 102/202, 50.

Despite using different algorithms, most unsupervised automatic phone segmentation methods achieve similar performance in terms of percentage correct boundary detection. Nevertheless, unsupervised segmentation algorithms are not able to perfectly reproduce manually obtained reference transcriptions. This paper investigates fundamental problems for unsupervised segmentation algorithms by comparing a phone segmentation obtained using only the acoustic information present in the signal with a reference segmentation created by human transcribers.

Purpose: This laboratory study compared visual-tactile examination with conventional radiographs, digital radiographs, and laser fluorescence in the detection of occlusal occult caries on extracted premolar teeth.

Methods: Extracted premolars without obvious caries or restorations were collected from school dental clinics. Occlusal surfaces of 320 extracted premolars were examined visually with an explorer, then examined using the KaVo Diagnodent unit and scored using specific criteria.
