College of Horticulture, Northwest A&F University, Xianyang 712100, China.

The bagging of fruits provides efficient protection from high-intensity sunlight and improves fruit color and quality. However, bagged fruit suddenly exposed to bright light can cause sunburn and destroys the peel cell structure. In this study, fruits from ten-year-old apple trees of 'Gala' variety were debagged, and the effect of sunburn on fruits was divided into: (1) normal peels (BFN), (2) peels with albefaction (BFA), and (3) browning (BFB).

Encouraging sun protection early in life: from a successful prevention programme in children to the identification of psychological barriers in adolescents.

J Eur Acad Dermatol Venereol 2022 Jun;36 Suppl 6:12-21

Child Development Unit, Hospices Civils de Lyon, Bron, France.

Children and adolescents have high rates of sunburn and high levels of ultraviolet radiation (UVR) exposure and are therefore at risk of developing skin cancer in later life. Minimizing UVR exposure in childhood and adolescence may be the most important component of skin cancer prevention efforts. Thus, age-adapted prevention campaigns, targeting children, adolescents and caregivers, are needed to change sun protection behaviour among individuals in these age groups. Read More

Anticancer treatments and photosensitivity.

V Sibaud

J Eur Acad Dermatol Venereol 2022 Jun;36 Suppl 6:51-58

Oncodermatology Department, Claudius REGAUD Institute and Cancer University Institute, Toulouse Oncopole, Toulouse Cedex 9, France.

Drug-induced photosensitivity is associated with a wide range of anticancer treatments, including conventional chemotherapeutic agents, targeted anticancer therapies, and immune checkpoint inhibitors. These dermatologic adverse events can have a major impact on the well-being and quality of life of cancer patients, leading to dose modifications and interruption or discontinuation of anticancer treatments in severe cases. However, the heterogeneous nature of the photosensitive reactions induced by these agents, as well as the common concomitant use of other potentially photosensitizing drugs (antibiotics, voriconazole, nonsteroidal anti-inflammatory drugs, etc. Read More

Anti-inflammatory effects of differential molecular weight Hyaluronic acids on UVB-induced calprotectin-mediated keratinocyte inflammation.

J Dermatol Sci 2022 Jun 9. Epub 2022 Jun 9.

Department of Dermatology, Ehime University Graduate School of Medicine, Shitsukawa, Touon-shi, Ehime, Japan.

Background: The biological functions of Hyaluronic acid are related to its molecular weight and binding to its receptor, Toll-like receptor4 (TLR4) or CD44. Recent studies have shown that low-molecular-weight Hyaluronic acid (LMW-HA) exhibits proinflammatory effects, while high-molecular-weight Hyaluronic acid (HMW-HA) functions as an anti-inflammatory factor. UVB-induced epidermal inflammation is mainly mediated by endogenous molecules, such as damage-associated molecular patterns (DAMPs), that cause severe skin damage by activating TLR signaling pathways.

Skin cancers in skin types IV-VI: Does the Fitzpatrick scale give a false sense of security?

Skin Health Dis 2021 Sep 8;1(3):e40. Epub 2021 Jun 8.

Department of Dermatology Norfolk and Norwich University Hospital Norwich UK.

The Fitzpatrick scale has been in use for skin colour typing according to the tanning potential of skin since its inception in 1975-1976. Thomas Fitzpatrick developed the scale to classify persons with 'white skin' in order to select the correct amount of UVA in Joules/cm for PUVA treatment for psoriasis. Since then, it has been widely used in Dermatology to gauge the skin's reaction to UV exposure, tanning potential, assessment of sunburn risk and amount of sun protection required for individual patients.
