BACKGROUND: Acne vulgaris is a multifaceted skin disorder, affecting more than 85% of young individuals worldwide. Pharmacological therapy is not always desirable because of the development of antibiotic resistance or the potential risk of adverse effects. Non-pharmacological therapies can be viable alternatives for conventional therapies. However, sufficient evidence based support in the efficacy and safety of non-pharmacological therapies is lacking. OBJECTIVE: To assess the efficacy and safety of several non-pharmacological therapies in the treatment of acne vulgaris...

Exposures to radiofrequency (RF) energy above 6 GHz are characterized by shallow energy penetration, typically limited to the skin, but the subsequent increase in skin temperature is largely determined by heat transport in subcutaneous layers. A detailed analysis of the energy reflection, absorption, and power density distribution requires a knowledge of the properties of the skin layers and their variations. We consider an anatomically detailed model consisting of 3 or 4 layers (stratum corneum, viable epidermis plus dermis, subcutaneous fat, and muscle)...

Treating patients with heavy or thick features comes with challenges not present in those patients lacking these physical characteristics. The authors report our experience with cool atmospheric plasma for facial contouring and skin rejuvenation of the heavy face and neck including rhinophyma. Cool atmospheric plasma is generated by running helium gas over radiofrequency energy. The resulting plasma is a fourth state of matter and has enhanced clinical effects for ablation and thinning of skin and soft tissues as well of contouring and tightening of deeper soft tissues and fascia...

The spread of radiofrequency electromagnetic fields (RF-EMF) is rising and health effects are still under investigation. RF-EMF promote oxidative stress, a condition involved in cancer onset, in several acute and chronic diseases and in vascular homeostasis. Although some evidences are still controversial, the WHO IARC classified RF-EMF as "possible carcinogenic to humans", and more recent studies suggested reproductive, metabolic and neurologic effects of RF-EMF, which are also able to alter bacterial antibiotic resistance...

Introduction: Radiofrequency ablation is an effective modality in treating osteoid osteoma while avoiding the complications of an open procedure. Its complications are usually self-limited consisting mostly of local skin burns. This report presents a major complication, a femur shaft fracture following an osteoid osteoma radiofrequency ablation. The fracture occurred approximately one year after the ablation at the site of the osteoid osteoma. Discussion: Few case reports have been published regarding subtrochanteric femur fracture after ablation of an osteoid osteoma...

BACKGROUND: Limits for exposure to radiofrequency (RF) contact currents are specified in the two dominant RF safety standards and guidelines developed by the Institute of Electrical and Electronics Engineers (IEEE) and the International Commission on Non-Ionizing Radiation Protection (ICNIRP). These limits are intended to prevent RF burns when contacting RF energized objects caused by high local tissue current densities. We explain what contact currents are and review some history of the relevant limits with an emphasis on so-called "touch" contacts, i...

The development of fractional photothermolysis has revolutionized the treatment of skin scarring, rejuvenation, and tightening. By creating targeted microthermal zones and leaving surrounding tissue intact, this concept has provided the field with efficacious results, with less downtime and a better safety profile. This has started to change the paradigm of what is considered first-line treatment for scarring and rejuvenation. While originally applied to nonablative lasers, fractionation has now been employed in ablative, quality-switched, picosecond, and novel hybrid fractional lasers...
