  1. Laser Therapy for Extra Facial PWS

Cretu S., et al.(Salavastru C.) – Romania

This is a retrospective analysis of 5 cases of difficult to treat PWS located in acral areas. They were treated with LP Nd:YAG laser for vascular nodules, PDL for the rest of lesions surface, and additional tacrolimus 0.1% ointment in 2 cases. The settings used were, for the LP Nd :YAG : 10-40 ms, 3 to 7 mm spot diameter, 120-140 J/cm² ; for the PDL 595 nm : 0.45-3 ms, 7 mm (7.25-10 J/cm²), 10 mm (5-12 J/cm²) or 3x10 mm (10-14 J/cm²) spot size.

Clearance of vascular nodules was obtained after an average of 4 sessions. More than 50% clearance was achieved after an average of 8 sessions for the rest of the lesions. No scarring was observed. Hyperpigmentation (lower limbs) was treated with depigmenting agents and PDL laser: 10mm spot size, 6J/cm², 7 mm, 7.5J/cm² with good results. Difficult to treat PWS located in acral areas, where the stratum corneum is thicker compared to the face, tend to have a pink or purple colour. Some authors have found that in distal extremities vessels are placed more deeply. In this trial, authors obtained good results without side-effects. Associated treatments with Tacrolimus ointment 0.1%.might inhibite angiogenesis and hence may prevent formation of new vessels.

  1. Treatment of Atrophic Scars with RF Microneedles

Badawi A. – Canada

The importance of electric potential on cells functioning is well established for wounds, in particular the increase of a negative electric potential increases cell healing capacity through various control signals. The microneedling , as a part of the '' pro-healing '' technics changes the electrical potential and cells regeneration ability but also increases local blood flow with intake of cellular nutrients and growth factors and stimulates inflammation with cytokine and fibroblast response. Beware of dermarollers, all are not equivalent and the tips become deteriorate and bend quickly. There are also motorized rollers as alternative.

For clinical results you can expect tightened pores, decrease in depth of scars and rejuvenation. Finally fractional RF with non isolated needles (epidermal and dermal heating) or isolated (dermal heating only) are also “pro-healing” ... but thermal effects long term fibroblast stimulation should be taken into consideration (3-6 months). Clinical case results: appears to be convincing on acne scars and stretch marks.

  1. Treatment of Acute and Chronic radiodermatitis

Laubach HJ – Switzerland

• Acute Radiodermatitis. Prevention

1. Class III topical corticosteroids applied 1 time per day (mometasone, bethametasone, methylprednisolone 0.1%) are more effective than the simple emollients and reduce incidence of Grade II acute radiation dermatitis.

Laser diode: 2 times a week together with radiation therapy, can reduce acute, grade II radiodermatitis from 29% in the control group to 3% in the treatment group (p = 0.001)

Also another clincal trial is currently on its way using LED 660 nm within 52 patients, 5 times a week, and applied just before the radiation treatment versus placebo. Results to be expected in 2016/17.
