Laser-Induced Smoke in Dermatologic Practice: A Survey to Explore Hazard Perceptions, Safety Measures and Unmet Needs.

Inhalation of laser-induced smoke is a potential health hazard to exposed physicians and laser operators. To date, little is known about the perception of health hazards related to laser-induced smoke exposure among physicians and the actual use of safety measures to mitigate these risks. In May 2020, 514 members of the European Society for Lasers and Energy-Based Devices (ESLD) were invited by email to participate in an online survey.

Allergic contact granuloma due to palladium following ear piercing.

Two cases of sarcoidal-type allergic contact granuloma due to metals in ear piercing are presented, the first to palladium (Pd) only, and the second to Pd and possibly also to other metals. Both the patients developed papulonodular lesions at the helices following ear piercing, which after 3-4 weeks, became more granulomatous and very resistant to treatment. Indeed, repeated intralesional injections with corticosteroids produced only a temporary regression of the lesions.
