Dynamic Evaluation of Skin Displacement by the Frontalis Muscle Contraction Using Three-Dimensional Skin Displacement Vector Analysis.
Understanding the muscle actions and resultant skin movement can enable more safe and effective botulinum toxin injection for the treatment of forehead wrinkles. We aimed to investigate skin displacement patterns of the forehead and adjacent skin due to frontalis muscle contraction using three-dimensional skin vector displacement analysis. ⋯ Botulinum toxin injection into the forehead can be individualized by considering the vector and asymmetry of skin displacement. Vertical or medial vector requires more centrally located injections, while laterial vector requires more laterally located injections. The presence and location of the vertical transition line are important for preventing ptosis when treating forehead lines with botulinum toxin. Glabellar movement during frontalis contraction suggests the need for a concomitant injection into the glabella to prevent glabella wrinkle accentuation.

Randomized Controlled TrialIntramuscular Injection of Autologous Serum in Adolescent and Adult Patients with Atopic Dermatitis: A Preliminary Randomized Clinical Trial.
The favorable clinical efficacies of intramuscular injection of autologous blood in patients with atopic dermatitis (AD) and intramuscular injection of autologous serum in patients with chronic urticaria have been demonstrated by randomized clinical trials. In this study, we assessed the clinical effectiveness and safety of the intramuscular injection of autologous serum in patients with AD. ⋯ Intramuscular injection of autologous serum may be effective in treating AD. Further studies are needed to evaluate the clinical usefulness of this intervention for AD (KCT0001969).

The Impact of Visual Impairment on Healthcare Use among Four Medical Institution Types: A Nationwide Retrospective Cohort Study in Korea.
The aim of this study was to determine the effect of visual impairment (VI) onset on the use of healthcare services across four types of institutions in South Korea. ⋯ Our findings suggest economic burden of healthcare in tertiary teaching hospitals during pre-VI onset period and a potential lack of regular management and continuity of care in post-VI periods.
