Radiation safety in the cardiac catheterisation laboratory
John Edward Boland, David W. M. Muller in Interventional Cardiology and Cardiac Catheterisation, 2019
Skin injuries attributable to X-rays from fluoroscopy has been reported over recent decades10 and the number of fluoroscopically guided interventions have increased dramatically over the last 30 years, and procedures have become more complex, more frequent and longer-lasting. More patients are obese, with patient size being a significant contributing factor to a high radiation dose. Radiation-induced skin injuries and epilation are the most commonly reported side effects of high-dose procedures,10 and the severity of effects is related to the skin radiation dose. The most common effect is early, transient erythema that can occur within a few hours or up to 24 hours following an exposure of more than 2 Gy.10 More serious effects, such as acute radiation injury and chronic radiation injury, following higher radiation exposure to the skin may occur weeks, months or years after exposure. As radiation-induced ulcers may occur with a long time delay and without obvious relationship to radiation exposure, it is important to provide information to the patient and to the referring doctor about a high radiation dose to assist in the correct diagnosis of skin injury, should it occur in the future.

Relative contraindications include the following: Younger patients below 45 years: There is potential for deterioration of the cosmetic outcome over time (<5–10 years) and risk of second malignancy.Large lesions involving cartilage, bone, tendons or joints: these may be treated with megavoltage or electron beam radiation.Lesions where there is uncertainty over the histology.Lesions that have recurred after RT.Hair-bearing skin such as scalp, eyebrow and eyelashes: risk of permanent epilation.Lesions around the upper eyelid: Risk of lachrymal gland dryness and upper lid conjunctival keratinization.Medial Inner Canthus lesions: Risk of nasolacrimal duct stenosis.Lesions on the lower leg and back: Poor healing and radiation sequelae, particularly telangiectasia, pigment changes, ulceration and atrophic scarring.

The “in’s and outs” of laser hair removal: a mini review
Published in Journal of Cosmetic and Laser Therapy, 2019

For many years’ temporary hair removal treatment options such as waxing, threading, tweezing and depilatory creams have been utilised, and are still being used. Although these methods are relatively inexpensive, convenient and easily accessible, the results are short-lived, and require regular repetitive treatments. Permanent hair removal can be attained through electrolysis and light based treatments. The use of electricity to damage the hair follicle can be painful and time consuming, and frequently leads to pigmentary disorders and scarring with poor application (2). Light-based hair removal technologies are grounded on either high-intensity, coherent, monochromatic, narrow-waveband lasers, or high-intensity, incoherent and polychromatic pulsed light (intense pulsed light, IPL). Along with significant advances in technology, laser hair removal, otherwise known as photo-epilation, has become a popular choice for the permanent reduction and removal of unwanted hairs. The concept of selectively targeting chromophores, known as selective photothermolysis, is an important concept in efforts to eradicate unwanted hairs, and relies on selectively targeting and destroying hair follicles through exposure to pulses of light, while causing minimal damage to surrounding tissue.

These physical therapies act by either removing the hair shaft from the surface, e.g., shaving and chemical hair removal (depilation) or from above the bulb, e.g. tweezing and waxing (epilation). There are several physical methods for hair removal with light-based hair reduction being the fastest growing modality due to being a noninvasive, efficient, and longer-term treatment. There are a variety of laser devices available and device choice depends on patient characteristics, such as skin type and hair color. Complications such as perifollicular edema, folliculitis, pigmentary changes, and scarring can occur [65]. Total removal of the already androgenized hair follicles will require electrolysis or laser hair removal. It is preferable to begin mechanical approaches after medical therapy has had an opportunity to inhibit hair growth, usually after 6–12 months [66].
Demodex and eye disease

Lash epilation is more widespread in research and accessible in a clinical setting than IVCM.106 Lash epilation is performed at the slitlamp, and lashes with CD are preferably selected as they have an increased mite count.39,66 Using a tweezer, the selected lash is held close to the root and pulled from its follicle and subsequently placed on a microscope slide for ex vivo viewing. The exact technique of lash manipulation is performed differently from one study to another, consequently rendering comparisons challenging. The lash is either pulled directly,1,66,105 rotated once or a few times,107 pulled laterally to one side108 or not specified.24,47,48,77,109
