Stem Cells in the Treatment of Refractory Chronic Migraines.

Background: Autologous adipose-derived stromal vascular fraction (SVF), which is rich in mesenchymal stromal cells, has been reported to be effective for the treatment of trigeminal neuropathic pain and chronic migraine and tension-type headaches. It is possible that stem cell activity targets neurogenic inflammation, which is a well-documented aspect of migraine pathogenesis.

Methods: Adult patients with severe migraine-related disability as measured by the Migraine Disability Assessment (MIDAS) score who failed botulinum toxin injections and at least 3 prophylactic drugs were included in this study.

Minimally Invasive Radiofrequency Devices.

This article reviews minimally invasive radiofrequency options for skin tightening, focusing on describing their mechanism of action and clinical profile in terms of safety and efficacy and presenting peer-reviewed articles associated with the specific technologies. Treatments offered by minimally invasive radiofrequency devices (fractional, microneedling, temperature-controlled) are increasing in popularity due to the dramatic effects they can have without requiring skin excision, downtime, or even extreme financial burden from the patient's perspective. Clinical applications thus far have yielded impressive results in treating signs of the aging face and neck, either as stand-alone or as postoperative maintenance treatments.

Aesthetic Applications of Radiofrequency Devices.

Radiofrequency (RF)-based devices are used to improve face and neck laxity, a major feature of aging that until recently could only be addressed with surgery. Although these treatments are not meant to replace surgical procedures, patient satisfaction studies have been consistently high. For physicians offering these skin rejuvenation procedures, it is essential to have intimate knowledge of how the devices work, select appropriate candidates, set realistic expectations, and combine treatments to optimize outcomes.

Radiofrequency Physics for Minimally Invasive Aesthetic Surgery.

Radiofrequency energy has a wide range of medical applications, including noninvasive treatment of wrinkles and body contouring. This technology works by differential heating of skin and soft tissue layers causing dermal remodeling or adipolysis, ultimately leading to observable effects. This article reviews the physics of radiofrequency as applied clinically.

Basics of Lasers: History, Physics, and Clinical Applications.

Lasers are increasingly used by plastic surgeons to address issues such as wrinkles and textural changes, skin laxity, hyperpigmentation, vascularity, and excess fat accumulation. A fundamental understanding of the underlying science and physics of laser technology is important for the safe and efficacious use of laser in medical settings. The purpose of this article was to give clinicians with limited exposure to lasers a basic understanding of the underlying science.
