Objective: To examine the efficacy and safety of a new fractional, ablative erbium:glass fiber (Er:glass) laser (2910 nm) at improving clinical signs of photodamaged skin.
Materials And Methods: Thirty-seven healthy participants aged 38-75 years with photodamaged skin were enrolled into two treatment groups. Group A (n = 14) received up to four laser treatments with mild settings, and focal facial subunits were treated with deeper settings.
Background: In addition to reducing subcutaneous fat for body contouring, some patients are interested in toning the underlying muscle layer.
Objective: This feasibility study evaluated the safety and efficacy of electromagnetic muscle stimulation (EMMS) alone, cryolipolysis alone, and cryolipolysis with EMMS for noninvasive contouring of abdomen.
Methods: Abdomens of 50 subjects were treated in a study with 3 cohorts: EMMS alone, Cryolipolysis alone, and Cryolipolysis + EMMS in combination.
Objectives: To evaluate long term effectiveness and safety with the use of a combined radiofrequency and optical home hair removal device in all skin types and over both facial and body areas.
Methods: A combined intense pulsed light (IPL) and radiofrequency (RF) home device was used for hair removal. Two separate study designs were evaluated.
Background And Objectives: Nano-pulse stimulation (NPS) therapy is the application of ultrafast pulses of high amplitude electrical energy to tissues to influence cell function. Unique characteristics of these pulses enable electric field penetration into the interior of cells and organelles to generate transient nanopores in both organelle and plasma membranes. The purpose of this study is to document the temporal and physical changes in intracellular organelles following NPS therapy using electron microscopy.

Objective: To evaluate the safety and efficacy of a single NPS treatment for clearing seborrheic keratoses (SKs).
Materials And Methods: This study was a prospective, randomized, open-label, multisite, nonsignificant risk trial in which each subject served as their own control.
Background: Nanosecond pulsed electric field (nsPEF) technology involves delivery of ultrashort pulses of electrical energy and is a nonthermal, drug-free technology that has demonstrated favorable effects on cellular structures of the dermis and epidermis.
Objective: Determine the tolerability and effectiveness of nsPEF treatment of sebaceous gland hyperplasia (SGH).
Methods: This study was a prospective, randomized, open-label, multisite, nonsignificant risk trial in which each subject served as their own control.
Background: A vasovagal reaction is a commonly encountered event in outpatient procedures. There is a paucity of discussion on vasovagal reactions (VVRs) in the dermatologic surgery literature. However, recent investigations in the physiology, evaluation, and treatment of VVRs have been reported in other specialties.

BACKGROUND: Fractional ablative lasers have been shown to be safe and effective for improving wrinkles, scars, skin texture, and dyspigmentation. However, the exact effects of this technology in vivo on epidermal and dermal skin constituents have not been delineated. This study evaluated the in vivo histological effects over time of treatment with a fractional ablative CO2 system, using different treatment parameters.

Objective: The authors compared the pain felt during injection of local anesthetic using a minimal needle insertion technique with a 30- or 33-gauge needle.
Materials And Methods: Three hundred eighteen patients with tumors on the head and neck were injected with lidocaine using a previously described technique with either a 30- or 33-gauge needle.
Methods: In this split-face, evaluator-blinded study, 18 subjects were randomly assigned to receive either the SSR or NFL treatments on each side of the face. For the SSR facial sides subjects followed two morning-evening regimens. On the NFL sides subjects were treated 3 times with the 1927-nm laser at 4-week intervals.

Background: A novel device using micro-focused ultrasound with high-resolution ultrasound visualization (MFU-V) produces non-invasive lifting and tightening of lax skin on the face and neck when treatment is delivered at a single focal depth (Ulthera® System; Ulthera, Inc., Mesa, AZ).
Objective: The following study was performed to test the hypothesis that customized application of MFU-V at two focal depths will produce clinical results that are superior to treatment at a single focal depth.
Background: Many over the counter topical products claim to reverse the signs of cutaneous photo-damage. To date, the two most studied ingredients for improving the texture, tone, and pigmentation of the skin are topical retinoids and hydroquinone.
Objective: This split face study compares a mass market skincare regimen with a prescription skin care regimen for improvement in photo damaged skin.
Background And Objectives: Cryolipolysis has previously received FDA clearance for fat reduction in the abdomen, flanks, and thighs. There is also interest in small volume fat reduction for areas such as the chin, knees, and axilla. This article reports the results of a cryolipolysis pivotal IDE study for reduction of submental fullness.

This study evaluates several specific attachment heads using a novel home skincare platform (HSP). By incorporating multiple treatment heads for cleansing, skin smoothing, and skin infusion, this device has the potential to address many potential treatment goals.

This article reports the results of an inner thigh study which contributed to FDA clearance of cryolipolysis for treatment of thighs.
Study Design/material And Methods: A flat cup vacuum applicator (CoolFit applicator, CoolSculpting System) was used to treat 45 subjects bilaterally in the inner thighs.
Background: Hyaluronic acid (HA) fillers are FDA approved for improving the appearance of the nasolabial folds. Previous reports on the use of HA for this treatment have focused on injections directly into the location of the desired correction. To our knowledge, a study has not been done evaluating the efficacy of injecting a low volume of HA into the adjacent area of volume loss to correct both volume loss and adjacent lines.

Xanthine oxidase (XO) is increased in human and rat left ventricular (LV) myocytes with volume overload (VO) of mitral regurgitation and aortocaval fistula (ACF). In the setting of increased ATP demand, XO-mediated ROS can decrease mitochondrial respiration and contractile function. Thus, we tested the hypothesis that XO inhibition improves cardiomyocyte bioenergetics and LV function in chronic ACF in the rat.
