Promoting tissue viability and caring for skin damaged as a result of radiotherapy are critical to the quality of care patients receive. However, few nurses recognise fully the effect of radiotherapy on tissue viability and wound healing. This article considers the causes and types of skin damage resulting from radiotherapy treatment that nurses may encounter, and how this damage can be graded....

Bone cement reaches significant temperatures and is known to cause thermal and chemical damage to various tissues. All the reports of such damage occurred following a direct contact of the tissue or structure with cement. We report the case of a patient with a giant cell tumour of the proximal tibia who underwent curettage and bone cement application through a posterior approach and subsequentl...

Eichhornia crassipes (Mart.) Solms possess many antioxidants like glutathione, ascorbic acid etc. Two skin creams of the ethyl acetate extract of E.crassipes were evaluated for its antiageing efficacy by DNA damage inhibition assay and DPPH radical scavenging assay. The DNA damage inhibition and DPPH radical scavenging ability offered by the skin creams increased with increase in concentration ...

Like the whole organism, skin follows the process of aging during life-time. Additional to internal factors, several environmental factors, such as solar radiation, considerably contribute to this process. While fundamental mechanisms regarding skin aging are known, new aspects of anti-aging agents such as melatonin are introduced. Melatonin is a hormone produced in the glandula pinealis that f...

UV skin exposure induces extensive generation of reactive oxygen species (ROS). These can react with DNA, proteins, fatty acids and saccharides causing oxidative damage. Such injuries result in a number of harmful effects: disturbed cell metabolism, morphological and ultrastructural changes, attack on the regulation pathways and, alterations in the differentiation, proliferation and apoptosis o...

Photocarcinogenesis and photoaging are established consequences of chronic exposure of human skin to solar irradiation. Accumulating evidence supports a causative involvement of UVA irradiation in skin photo-damage. UVA photodamage has been attributed to photosensitization by endogenous skin chromophores leading to the formation of reactive oxygen species and organic free radicals as key mediat...

Human skin is body's vital organ constantly exposed to abiotic oxidative stress. This can have deleterious effects on skin such as darkening, skin damage, and aging. Plant-derived products having skin-protective effects are well-known traditionally. Triphala, a formulation of three fruit products, is one of the most important rasayana drugs used in Ayurveda. Several skin care products based on ...

Retrospective study of 59 chlidren with JLS from 3 to 17 y (M = 10.3) treated with MTX was performed. Group 1 (n = 18) – received prednisone 0.5 mg\kg for 6 weeks, taped to 0.1 mg\kg for 12 months + MTX 10 mg\body sq. weekly for 13.7 mo. Group 2 (n = 41) -MTX the same doses and duration. The efficacy was measured in 6 & 12 months using skin score, activity and sclerosis indexes (IA, IS) (1 – 3 ...

Exposure to UV radiation can cause skin damage; among UV rays UVB are commonly considered to be more important in inducing photoaging and skin cancer; however in recent years some authors have claimed an important role also for UVA that can concur with UVB to damage the skin. UVB rays have a wavelength between 280 and 320 nm and are responsible for immediate skin damage represented by erythema....
