Energy-Based Devices for the Treatment of Cutaneous Verrucae: A Systematic Review.

BACKGROUND: Warts are one of the most common benign neoplasms caused by human papillomavirus infection and often pose a therapeutic challenge. OBJECTIVE: To summarize the current evidence on the safety and efficacy of laser and energy-based devices for the treatment of cutaneous verrucae. METHODS: A comprehensive systematic review of the literature on laser and energy-based devices for the treatment of cutaneous verrucae was performed. RESULTS: A total of 904 unique studies were identified, of which 109 were included in this review. The most commonly used lasers as a single treatment modality for verrucae included the long-pulsed Nd:Yag (n = 20) and pulsed dye (n = 18) lasers. Other modalities included the CO2 ablative laser (n = 10), photodynamic therapy (n = 11), local hyperthermia (n = 11), microwave therapy (n = 2), and nanopulse stimulation (n = 1). Other studies combined energy-based modalities with additional treatments, such as retinoids, imiquimod, and intralesional bleomycin. Overall, such devices were generally well-tolerated, with only a mild side effect profile. CONCLUSION: Overall, the use of laser and energy-based devices is a safe and well-tolerated option for cutaneous verrucae that is relatively less invasive than surgical interventions. Future studies using more consistent outcome assessment tools will be valuable to help clinicians develop device-specific protocols and treatment regimens to ensure replicable and effective outcomes.

Alternative Cosmetic and Medical Applications of Injectable Deoxycholic Acid: A Systematic Review.

BACKGROUND: Beyond submental fat reduction, injectable deoxycholic acid (DCA) has gained popularity in recent years for various minimally invasive lipolysis applications. OBJECTIVE: To summarize and evaluate the evidence of off-label uses of injectable DCA. METHODS: MEDLINE, Embase, CINAHL, Web of Science, and CENTRAL were searched. The outcomes measured included applications of DCA, treatment regimen, and its efficacy. An overall success rate for each condition was calculated based on the improvement defined in the included studies. RESULTS: Eleven studies evaluated the cosmetic use of DCA for excess adipose tissue on various anatomical locations. The outcomes were evaluated at time points ranging from 1 to 21 months post-treatment, with overall success rates over 85%. Eight case reports and series reported the success of using DCA treating lipomas, xanthelasmas, paradoxical adipose hyperplasia, fibrofatty residue of infantile hemangioma, piezogenic pedal papules, and HIV-associated lipohypertrophy. Although the preliminary efficacies were high, the overall recommendations for off-label uses are weak because of the lack of high-level studies. CONCLUSION: The review emphasizes the diversity of injectable DCA as a minimally invasive technique for lipolysis. Further high-level studies demonstrating consistent treatment regimens and methods of evaluation are warranted to make more definitive recommendations regarding off-label DCA use.

The Use of Lasers and Light Devices in Acne Management: An Update.

Acne vulgaris is a disease of the pilosebaceous unit and the most common inflammatory dermatosis worldwide. It is also associated with significant economic burden. Limitations of conventional topical and systemic treatments include long treatment course, intolerable adverse effects, antibiotic resistance, and patient compliance. Therefore, laser and light-based interventions present as alternative options over the past decade and have been used in combination with conventional pharmacological therapies and other physical modalities. An updated overview on the use of lasers and light-based devices in acne management is presented to help clinicians understand the safety and efficacy of these treatment options. The effectiveness of neodymium:yttrium aluminum garnet (Nd:YAG) for treating acne is supported by more high-level studies compared with other laser devices. There is limited evidence to support the use of CO2 lasers, potassium titanyl phosphate lasers, and 1565-nm non-ablative fractional lasers for treating acne. Among light devices, photodynamic therapy is the most studied, showing higher efficacies than some of the conventional topical and oral acne therapies. Intense-pulsed light and blue light therapies also show favorable outcomes. A limitation is that most studies are non-randomized and lack a control group, and report on a variety of device settings, treatment regimens, and outcome measures, making it challenging to summarize and generalize findings. Although the use of laser and light devices to treat acne is promising, further work with randomized controlled study designs and larger sample sizes will provide improved guidance on the application of these modalities.

89% Vichy mineralizing water with hyaluronic acid is a well-tolerated adjunct treatment that helps restore skin barrier function in dry skin-related inflammatory dermatoses and post-procedure skin care: A Canadian study.

INTRODUCTION: Minéral 89 (M89), comprised of 89% Vichy mineralizing water and hyaluronic acid, has been formulated to help strengthen and restore skin barrier. AIM: Assess tolerance and efficacy of M89 in post-esthetic procedures and dry skin-related facial dermatoses. METHOD: Adults post-esthetic procedure or presenting with inflammatory dermatoses (47 subjects; mean age 40.9 ± 13.2 years; any Fitzpatrick or skin phototype), applied M89 for 4 weeks, once or twice daily, as an adjuvant treatment. Information on clinical signs and subject-reported symptoms, skin characteristics, tolerance, and subject and investigator satisfaction were collected. RESULTS: Following 4 weeks of M89 use, significant decreases with complete resolution of erythema (27.6%), desquamation (29.8%), irritation (32%), and skin dehydration (35.8%), as compared to baseline signs and symptoms, were observed. Overall grading improvements for erythema (84.8%; p < 0.001), desquamation (91.7%; %; p < 0.003), irritation (91.7%; %; p < 0.015), and skin hydration (46.2%; p < 0.015) were noted. There was no significant improvement in papules and pustules. Evaluation of subjective signs demonstrated significant decreases in skin sensations such as burning (-73%; p < 0.0001), itching (-71%; p < 0.0001), stinging-tingling (-66.7%; p < 0.0001), as well as in skin dryness (-60%; p < 0.0001). M89 texture was rated very pleasant by 90% of patients. Investigators assessed M89 tolerance to be either good or very good (93%), and satisfactory or highly satisfactory impact on patient's skin (91.5%). CONCLUSION: M89 is a highly tolerable adjuvant treatment that significantly improved clinical signs and symptoms related to a compromised skin barrier in various facial dermatoses and post-aesthetic procedures.

Dermatologic Laser Side Effects and Complications: Prevention and Management.

The evolution of modern laser and light-based systems has mirrored the demand for clinically effective treatments and the need for safer technologies with reduced postoperative recovery, side effects, and complications. With each new generation of lasers, more selective tissue destruction can be achieved with reduced unwanted sequelae. Patient selection and preparation, operator technique, and expeditious recognition and management of post-treatment side effects are paramount in avoiding complications and patient dissatisfaction. An overview of important variables to consider for dermatologic laser treatments are presented in order to provide a framework to reduce the severity and duration of possible post-treatment side effects and complications.

Microneedling Treatment of Striae Distensae in Light and Dark Skin With Long-Term Follow-Up.

BACKGROUND: Striae distensae have notoriously been difficult to treat due to their extensive involvement of nonfacial skin. Microneedling with its lack of thermal injury during microneedling treatment renders it a viable treatment option in darker skin tones and nonfacial regions due to the reduced risk of postinflammatory hyperpigmentation. OBJECTIVE: To describe the clinical results and side effects of microneedling in a series of 25 individuals with striae distensae. MATERIALS AND METHODS: Twenty-five consecutive adults (SPT I-V) with striae distensae involving the trunk and extremities were treated using a microneedling device. No additional treatments (topical or intralesional) were applied. Two assessors blinded to treatment protocol rated clinical improvement of striae on a 5-point scale. Side effects were monitored and tabulated. RESULTS: Patients received 1 to 3 consecutive monthly treatments. All striae improved at least 50% after an average of 1.8 treatments, and 28% of patients demonstrated more than 75% clinical improvement. Striae in thicker skin regions (e.g., buttocks/thighs) showed comparable clinical improvement than those in thinner skin areas (e.g., breasts) and did not require additional treatment sessions. Side effects were limited to transient erythema in all skin phototypes. No infections or dyspigmentation were observed. CONCLUSION: The clinical results obtained in this study support the safe and effective treatment of striae distensae with microneedling in light and dark skin tones in various body locations. Standardization of treatment protocols are anticipated with further (ongoing) studies.

Laser Therapy for an Acquired Glomuvenous Malformation (Glomus Tumour): A Nonsurgical Approach.

BACKGROUND: Glomuvenous malformations (GVMs) (previously known as glomus tumours) are uncommon, benign, vascular neoplasms. Current treatments include surgical excision and sclerotherapy, often with high recurrence rates and poor cosmetic results. OBJECTIVE: We sought to use a nonsurgical approach for treatment of a GVM. METHODS: We present a patient with an acquired, biopsy-proven GVM of the heel unamenable to surgical excision, treated with a long pulsed 1064-nm neodymium-doped yttrium aluminum garnet (Nd:YAG) laser. RESULTS: Excellent cosmesis and long-term remission were achieved after several treatment sessions. CONCLUSION: Our experience provides further evidence to support the safety and effectiveness of the 1064-nm Nd:YAG laser in the management of large and surgically challenging GVMs.
