Electromagnetic interference from lasers and intense light sources in the treatment of patients with artificial pacemakers and other implantable cardiac devices.

Measurements of the electric and magnetic field strengths surrounding six laser systems and one intense pulsed light system were carried out. The results were compared to exposure limits published by cardiac device manufacturers to assess the risk of electromagnetic interference to implantable cardiac devices such as pacemakers or implantable cardioverter defibrillators. The majority of lasers assessed in this study were found to produce electric and magnetic field strengths below the published exposure limits for cardiac devices.

Cutaneous lasers and skin camouflage make-up: a useful alternative intervention for periorbital hairy congenital melanocytic naevus.

Periorbital congenital melanocytic naevi can be very disfiguring and difficult to treat effectively. Although surgical excision and reconstruction is the most widely accepted treatment strategy, we describe a case in which cutaneous lasers treatment followed by the application of cosmetic skin camouflage make-up provided an alternative solution delivering a good cosmetic improvement.

Adverse effects reported in pulsed dye laser treatment for port wine stains.

A retrospective study was conducted over a 762-day period to investigate the incidence of adverse effects following pulsed dye laser treatment for port wine stains using the Chromos 585 nm pulsed dye laser (PDL). Treatment energy densities typically ranged from 4.0 J/cm(2) to 7.
