Randomized Controlled TrialComparative evaluation of Gracilaria algae 3% cream vs Clobetasol 0.05% cream in treatment of plaque type psoriasis: A randomized, split-body, triple-blinded clinical trial.
Gracilaria algae is red macro algae which has demonstrated considerable anti-inflammatory effects. Our objective was to compare the efficacy of Gracilaria algae topical cream 3% vs Clobetasol cream 0.05% in treatment of plaque-type psoriasis. Thirty adult patients with baseline modified Psoriasis Area and Severity Index (PASI) score ≤12 were randomized to receive either Clobetasol or Gracilaria algae cream on right or left-sided symmetric plaques once daily for 8 weeks and follow-up of 4 weeks. ⋯ No significant difference was found regarding mean physician global assessment score between the two groups (P > .05). Patients' satisfaction was significantly higher in favor of algae cream only at week 8 of the intervention (P < .05). Gracilaria algae cream can be an effective and safe alternative of Clobetasol in the treatment of plaque type psoriasis.

No SARS-CoV-2 antibody response in 25 patients with pseudo-chilblains.
Chilblain-like acral lesions have been identified in some coronavirus disease 2019 (COVID-19) patients. It has been suggested that these pseudo-chilblains could be a specific marker of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Most patients with these lesions have had negative polymerase chain reactions (PCRs), but some authors believe serology tests are likely to give positive results. ⋯ Our findings counter the hypothesis that serology is likely to reveal SARS-CoV-2 infection in patients with pseudo-chilblains. One hypothesis for our negative results is that the time period between symptom onset and antibody production is longer in these patients; another is that the lesions are caused by behavioral changes during lockdown rather than SARS-CoV-2 infection. We nevertheless maintain that COVID-19 should be ruled out in people presenting with chilblain-like lesions.

Efficacy of resveratrol in the wound healing process by reducing oxidative stress and promoting fibroblast cell proliferation and migration.
Oxidative stress (OS) is implicated in the pathogenesis of diabetic, chronic, and inflamed wounds. In these cases, wound healing is difficult and remains a big clinical challenge. As fibroblasts are crucial in wound healing by producing extracellular matrix and wound contraction, the researchers investigated the resveratrol (RES) effects as a potential therapeutic alternative, on an in vitro OS and wound healing model established by 3T3 Swiss Albino fibroblasts. ⋯ RES application reduced OS levels and stabilized cell proliferation, but no differences were found in COL1A2 mRNA expression. RES-treated cells showed better proliferation, migration rates, and ultrastructural preservation. RES administration decreases OS levels and improves the healing process by increasing cell proliferation and migration quality, suggesting it is a powerful candidate for the treatment of skin wounds.

Contact dermatitis due to masks and respirators during COVID-19 pandemic: What we should know and what we should do.
Given the current lack of a therapeutic vaccine for coronavirus disease 2019 (COVID-19), preventive measures including mask wearing are crucial in slowing the transmission of cases. However, prolonged wearing of protective respirators, medical and fabric masks can easily generate excessive sweating, moisture and friction. Closed and warm environments heighten the skin's permeability and sensitivity to physical or chemical irritants, leading to chronic cumulative irritant contact dermatitis or, rarely, even allergic contact dermatitis. ⋯ To minimize the skin breakdown, adherence to standards on wearing protective and safe equipments and avoidance of overprotection should be performed. At the same time, some measures of skin care are recommended. Here, we offer some tips on how to prevent and manage contact dermatitis due to masks not only in health care workers, but also in the general population during this COVID-19 outbreak.
