Research found that over 75% of people with the ABCC11 gene variant don't produce under-arm odour but use deodorant. However, only a quarter of these individuals realize they don't produce odour and don't use deodorant, while three quarters do. The study suggests that socio-cultural norms play a significant role in deodorant usage.
A study found that smartphone apps incorrectly diagnose 30% or more melanomas as 'unconcerning', potentially delaying doctor visits and life-saving treatment. The apps often lack regulatory oversight and are marketed to nonclinical users, increasing the risk of harm to the uninsured or economically disadvantaged.

Researchers found that EVLT and HLS are effective treatments for varicose veins, with similar rates of clinical recurrence. However, EVLT was associated with more adverse effects and improved hemodynamics, while HLS had a lower rate of saphenofemoral vein recurrences.
A new study found that combination immunotherapy nearly doubles five-year survival among patients with advanced Sezary Syndrome, a rare leukemic form of cutaneous T-cell lymphoma. The therapy approach comprised extracorporeal photopheresis and systemic immunostimulatory agents.
Among patients referred by non-dermatologists, only one-fifth had a malignant primary lesion, while nearly half of all skin cancers discovered were not the referral lesion. Dermatologists found additional incidental malignant lesions, highlighting the importance of focused education on skin cancer detection.
A survey of physicians in dermatology, cardiology, and orthopedics found that 75% of dermatologists and 91% of orthopedic specialists use dietary supplements, while 66% and 72% recommend them to patients respectively. The most commonly used supplements were multivitamins and omega-3/fish oil supplements.

A survey of patients undergoing skin cancer screening reveals that women are more likely to seek screening due to a skin lesion, family history, or sun exposure concerns. In contrast, men over 50 tend to only seek screenings after a previous skin cancer diagnosis.
A study conducted by a joint team of researchers from Ben-Gurion University of the Negev and the University of Miami Miller School of Medicine found significant disparities in skin cancer knowledge among male and female medical students in Florida. The study revealed that men had lower knowledge levels, less appreciation for sun protec...
The University of Michigan Health System has received the first 1,250 DNA samples from the National Psoriasis Victor Henschel BioBank, the largest single collection of psoriasis DNA samples. The samples will be used to identify new genes that increase a person's risk factor for developing psoriasis and examine its connection with other...
Researchers found that some body areas are more resistant to tanning than others, with the buttock being particularly resistant. People with no freckles also tanned more easily than those with freckling.
