Laser and light therapy for onychomycosis: a systematic review.

More than just a cosmetic concern, onychomycosis is a prevalent and extremely difficult condition to treat. In older and diabetic populations, severe onychomycosis may possibly serve as a nidus for infection, and other more serious complications may ensue. Many treatment modalities for the treatment of onychomycosis have been studied, including topical lacquers and ointments, oral antifungals, surgical and chemical nail avulsion, and lasers. Due to their minimally invasive nature and potential to restore clear nail growth with relatively few sessions, lasers have become a popular option in the treatment of onychomycosis for both physicians and patients. Laser or light systems that have been investigated for this indication include the carbon dioxide, neodymium-doped yttrium aluminum garnet, 870/930-nm combination, and femtosecond infrared 800-nm lasers, in addition to photodynamic and ultraviolet light therapy. This systematic review will discuss each of these modalities as well as their respective currently published, peer-reviewed literature.

Intralesional treatment for keloids and hypertrophic scars: a review.

BACKGROUND: Although differing in clinical presentation and prognosis, keloids and hypertrophic scars are generally characterized by abnormally proliferative scar tissue and are extremely debilitating. Several intralesional therapies have been studied in attempts to find a universally safe and effective modality, of which there are currently none. OBJECTIVE: To provide a comprehensive review of current intralesional treatment modalities for keloids and hypertrophic scars. METHODS AND MATERIALS: A PubMed search was performed for literature pertaining to intralesional treatment modalities for keloids and hypertrophic scars. References from retrieved articles were also considered for review. RESULTS AND CONCLUSION: Many intralesional therapies for keloids and hypertrophic scars are currently available to physicians and patients. Mechanisms of action and side effect profiles vary between these agents, and new approaches to keloids and hypertrophic scars are frequently being explored. Randomized controlled trials are needed to assess these new and promising modalities fully.

Inflammatory nodules following soft tissue filler use: a review of causative agents, pathology and treatment options.

Nodule development is a common complication following the use of fillers for soft tissue augmentation and is commonly categorized as inflammatory or non-inflammatory in nature. Inflammatory nodules may appear anywhere from days to years after treatment, whereas non-inflammatory nodules are typically seen immediately following implantation and are usually secondary to improper placement of the filler. Although inflammatory nodules are more common with permanent fillers such as silicone, inflammatory nodule development following administration of temporary fillers such as hyaluronic acid and collagen has also been reported. Treated many times with corticosteroids due to their anti-inflammatory properties, inflammatory nodules may be secondary to infection or biofilm formation, warranting the use of alternative agents. Appropriate and prompt diagnosis is important in avoiding delay of treatment or long-term complications for the patient. This paper addresses the etiology, development, and studied treatment options available for inflammatory nodules secondary to each of the major classes of fillers. With this knowledge, practitioners may expeditiously recognize and manage this common side effect and thus maximize functional and aesthetic benefit.
