Comparison of botulinum toxin A formulations for treating glabellar strain
Authors of a JAMA Dermatology study investigated differences among four formulations of botulinum toxin A for glabellar strain in women. In this randomized clinical trial of adult female individuals, abobotulinum toxin A (ABoNT/A) and prabotulinum toxin A (PBoNT/A) displayed the most rapid onset, and incobotulinum toxin A and PBoNT/A exhibited lasting effect at 180 days.

Prabotulinum toxin A exhibited a significantly greater effect at 180 days than onabotulinum toxin A, but all formulations resulted in significant improvement in strain and patient satisfaction up to 90 days. The authors found that ABoNT/A and PBoNT/A displayed the most rapid onset of effect, although the peak effect was similar across all toxins.

DermWorld Insights and Inquiries: Trichobacteriosis — A salute to the Shelleys
What we learn early stays with us, even if new knowledge challenges old dogma. No one suggests that mycosis fungoides is anything other than a cutaneous T-cell lymphoma, yet the term persists. Murphy and Maiberger correctly assert that trichomycosis axillaris (TMA) is a misnomer because it is a superficial bacterial infection of the hair caused by corynebacterium species instead of fungi. Newer literature prefers the precise term “trichobacteriosis” (TB). TMA is associated with factors such as localized hyperhidrosis, obesity, humid environments, and poor hygiene. Although most cases affect axillary hair, pubic and perianal hair may also rarely be involved. TMA may be asymptomatic; some may experience bromhidrosis (body odor) or chromhidrosis (colored sweat). Initially, the bacterial concretions are invisible, with only a perceived thickening of the hair on palpation. Keep reading!

Is hypochlorous acid beneficial for inflammatory skin conditions?
According to Medpage Today, searches for “hypochlorous acid” have dramatically increased in the past year with makeup brands and other skin-fluencers touting its benefits. Dermatologists explained that hypochlorous acid can be useful for some skin conditions and that the product has long been known to have antimicrobial activity to help with wounds and sterilization. Unlike alcohol, hypochlorous acid is effective at targeting both gram-positive bacteria (strep and staph infections) as well as gram-negative bacteria (Pseudomonas and E. coli).

Applying hypochlorous acid can reduce counts for the bacteria that cause acne, eczema, and psoriasis flare ups, said Shilpi Khetarpal, MD, FAAD, a dermatologist with the Cleveland Clinic. While it won’t cure these conditions, she noted, it can be incorporated into a skin care routine. She cautioned against applying hypochlorous acid more than a few times daily since it can damage good bacteria.

How do patients want physicians to dress?
An article published in BMJ Open analyzed patient perceptions of physician attire, focusing on its impact on the physician–patient relationship across different medical settings and specialties. Patient preferences for physician attire varied significantly by clinical context, medical specialty, and physician gender. In primary care settings, patients preferred a combination of casual attire and white coats, which may foster approachability and effective communication. In emergency rooms, patients tended to favor physicians dressed in scrubs or white coats, the authors noted.

Male physicians were perceived as more professional when wearing formal attire with white coats, while female physicians in similar attire were often misidentified as nurses or assistants. Specialty-based differences were also observed, with preferences for white coats in dermatology, neurosurgery, and ophthalmology, while scrubs were preferred in anesthesiology and gastroenterology.
