Dermatologists and other medical professionals all over Canada and the U.S. have reacted to the killing of George Floyd by police in Minneapolis and the protests that have ensued.
A single gene variation may determine if melanoma metastasizes
Inherited gene variations may dictate how cancers such as melanoma metastasize in an individual’s body, according to a new study.
Skin barrier gene defect linked to eczema in babies
Filaggrin gene defects may be linked to the development of eczema sooner than previously thought in newborn babies, based on information from a new study. Wheeze and nasal disease were also linked to the common skin barrier defect, according to the study published in the Journal of Allergy and Clinical Immunology (Apr. 28, 2020).
Digital face-aging app may help curb risky tanning behaviours
After viewing photos of their faces that had been digitally aged, students enrolled in a study changed their sun tanning behaviours, according to new research. The study, published online in JAMA Dermatology (May 6, 2020), looked at the behaviours of 1,573 students in 52 middle school classes in Brazil.
Three types of skin injury linked to PPE
A new study has identified three types of skin injury caused by use of personal protective equipment (PPE). According to researchers, usage of PPE by medical staff can cause device-related skin pressure injuries, skin damage related to moisture, and skin tear. The first-in-kind study was published online ahead of print in Advances in Wound Care (April 27, 2020).
Survey: Most know UV protection is important, but still fail to protect themselves
May is Skin Cancer Awareness Month in the U.S., and the American Academy of Dermatology (AAD) has released the results of a survey that found that although most Americans know sun protection is important, they still fail to adequately protect themselves from ultraviolet light (UV) exposure. A second press release from the AAD also said that there is no evidence to support claims that UV exposure may be effective in treating Covid-19, warning the public that the risks of UV radiation outweigh any perceived positive effects.
Case study identifies foot lesions as potential Covid-19 symptom
A case study of a 13-year-old boy found evidence that acro-ischemia manifesting in the form of lesions on the toes may be a symptom in severe cases of Covid-19. Researchers in Italy investigated the case of a boy, who was observed to have foot lesions on Mar. 8, 2020.
Brain-skin connection in psoriasis pathogenesis strengthened by new study
A new study has found evidence that neuropeptides may be an important factor in the pathogenesis of psoriasis. Though there are well documented genetic and environmental factors for psoriasis evidence that neuropeptides released by the cutaneous nervous system and the skin microbiome influence the development of psoriasis, strengthens the brain-skin connection of the disease, researchers said.
New insights into T cell reaction to UVR inflammation
Exposure to ultraviolet radiation causes a pair of specific T cell types in the skin to intervene to suppress inflammation and help the skin repair itself, according to a new study. The study, published online in Clinical & Translational Immunology (Apr. 2, 2020), found that T cells D4+GATA3+ and CD8+GATA3+ are sent to the inflamed area and can affect the area for two weeks.
Researchers: New AI algorithm could empower dermatologists
A new artificial intelligence-based algorithm intended to help diagnose a wider range of skin conditions than other currently available technologies has been developed by researchers in South Korea. According to researchers at Seoul National University, in Seoul, Korea, the algorithm is an advancement because it focuses on a wider range skin conditions beyond the detection of skin cancer.
