PURPOSE: The aim of this study was to evaluate the long-term success rate of oral leukoplakia treatments by using different laser-supported surgical protocols. PATIENTS AND METHODS: Overall, 2347 diagnosed homogeneous oral leukoplakias were treated with CO2 laser and were included in this study. Different surgical protocols (P) were used: P1 (SV = superficial scanning) was a complete superficial vaporization of the leukoplakia by a scanning mode in two passages respecting an overlapping...

OBJECTIVES: To evaluate the safety and long-term efficacy of fractional CO2 laser treatment in reducing the severity of symptoms of genitourinary syndrome of menopause (GSM) in menopausal women. STUDY DESIGN: 102 women presenting with symptomatic GSM were treated with the fractional CO2 laser (MonaLisa Touch, DEKA) system across a series of treatments delivered at intervals of six or more weeks. The Australian Pelvic Floor Questionnaire was used to gather data on sexual function and side-effects at three time-points across the study period (prospective panel design study)...

This case report describes the use of CO2 laser and quadrivalent human papillomavirus (HPV) vaccination in two patients with nasopharyngeal HPV11-positive recurrent respiratory papillomas (RRP). These patients initially underwent CO2 laser excision but developed recurrent lesions and underwent HPV vaccination as adjunct therapy. The recurrent lesions shrank after vaccination and were again excised with CO2 laser. Subsequently, these patients had no recurrence of lesions on long-term follow-up at 33 months or 6 years after surgery...

BACKGROUND: Autologous non-cultured cell suspension transplantation is an effective treatment for repigmentation in segmental vitiligo and piebaldism. Full surface laser ablation is frequently used to prepare the recipient site before cell suspension transplantation, even though optimal laser settings and ablation depth are unknown. OBJECTIVES: To assess the efficacy and safety of less invasive recipient site preparations. METHODS: In a randomised, observer-blinded, controlled trial we compared different recipient site preparations before cell suspension transplantation in segmental vitiligo and piebaldism...

In this study, we aimed to quantify the effects of fractional ablative carbon dioxide laser therapy in the treatment of widespread hypertrophic burn scars. While many different pilot studies have described the potential of the technology and expert groups and current guidelines, alike, recommend its use, the level of evidence for the efficacy of fractional CO2-laser treatment for burn scars is currently very low. Ten patients (three male, seven female) with hypertrophic burn scars were treated with a single course of fractional CO2-laser therapy in an in-patient controlled setup, using a standardized treatment paradigm...

BACKGROUND: Aminolevulinic acid (ALA) photodynamic therapy (PDT) is an established treatment option for actinic keratosis (AK), and recently fractional carbon dioxide (CO2) laser was shown to improve outcomes; but studies of short incubation photosensitizer are lacking. OBJECTIVE: Assess the efficacy of short incubation ALA followed by blue light PDT with and without previous fractional CO2 treatment for the treatment of AK. METHODS: Randomized, paired split-design, controlled trial of fractional CO2 followed by ultrashort 15-minute versus 30-minute incubation ALA and blue light PDT for the treatment of AK on the face...

BACKGROUND: Q-switched lasers are conventionally used for the treatment of black tattoo. However they require multiple sittings and the response may be slow due to competing epidermal pigment in dark skin. OBJECTIVE: To compare the efficacy of Q Switched Nd:YAG laser alone with its combination with ultrapulse CO2 in black tattoo removal. MATERIALS AND METHODS: Sixty patients of black tattoo were randomized into two groups. Group A was treated with QS Nd:YAG laser (1064 nm) alone and group B received combination of ablative ultrapulse CO2 followed by fixed dose QS Nd:YAG laser (1064 nm), at 6 weeks interval for a maximum of 6 sittings...

The applicability of dynamic light scattering (DLS) for the characterization of the size of supercritical carbon dioxide (sc-CO2)-swollen micelles in a polyester polyol-based multicomponent microemulsion with nonionic surfactant has been thoroughly proved for the first time in this work. Systematic experiments confirming that a hydrodynamic mode is observable in either a homodyne or a heterodyne detection scheme as well as the evaluation of the influence of the laser power applied to the slightly colored microemulsion have ensured an accurate implementation of this technique for a technically relevant system...

The study evaluates the ability of extrudates to deliver coumarin particles micronized by the rapid expansion of supercritical solutions (RESS). The RESS parameters were drug load (2-50 g), pressure (15-42 MPa) and temperature (40-60°C) in the extraction and pressure in the expansion (0.1-5 MPa) chambers in batch or continuous and CO2 flow rate in the continuous mode of operation. Particles were characterized for size (laser diffractometry, optical and electronic microscopies-19-61 μm), surface area (BET-0...

AIM: Debridement of fibrin and necrotic tissue from the ulcer surface is an important component of the treatment of diabetic ulcers. A possible alternative to standard lancets is represented by CO2 laser, which vaporizes necrotic tissues together with any pathogen. The present trial is aimed at verifying the effect of a CO2 laser on bacterial load in the debridement of infected diabetic foot ulcers. METHODS: In this open-label randomized controlled trial (NCT02677779), patients with diabetes and an infected foot ulcers were randomized to either CO2 laser or traditional debridement...

OBJECTIVE: It is the aim of this study to evaluate if the CO2 laser can beneficially be applied for excising epulides. BACKGROUND DATA: The standard procedure for treating epulides involves the excision of the hyperplastic tissue followed in most cases by the removal of parts of the underlying bone and the final closure of the wound by a flap. The use of the CO2 laser for the treatment of epulides has been documented only in isolated case reports and very few case series...

BACKGROUND: Scar management using laser phototherapy continues to evolve as it gains wide acceptance among patients and providers. Despite widespread use of laser therapy, there are no guidelines or consensus published regarding optimal pre- and post-procedure patient management. Our objective is to gain insight into the best laser practices; we decided to poll colleagues nationwide. METHODS: An online survey was distributed to members of the American Society of Plastic Surgeons...

Ordered mesoporous indium oxide nanocrystal (m-In2O3) was synthesized by nanocasting technique, in which highly ordered mesoporous silca (SBA-15) was used as structural matrix. X-ray diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM) Brunauer-Emmett-Teller (BET) and Barrett-Joyner-Halanda (BJH) studies were carried out on m-In2O3 and the results revealed that this material has a highly ordered mesoporous surface with reduced grain size, increased surface area and surface volume compared to the non porous indium oxide...

Studies of topical treatments for leishmaniasis were systematically reviewed, to evaluate the therapeutic efficacy, safety and any adverse effects of these treatments. The papers identified in the databases PubMed and Web of Knowledge involved eight studies with a total of 1744 patients. The majority of trials was from Iran (4/8), covered a period of 8 years (2003-2011), and included patients 4-85 years of age. The most frequent Leishmania species in the studies were L. tropica (4/8) and L. major (2/8). The treatments administered were thermotherapy, paromomycin and combinations, CO2 laser, 5-aminolevulinic acid hydrochloride (10%) plus visible red light (633 nm) and cryotherapy...

REVIEW
Marco Gambacciani, Santiago Palacios
Laser therapy has a therapeutic role in various medical conditions and most recently has gained interest as a non-hormonal treatment for genitourinary syndrome of menopause (GSM) and as a non-invasive option for stress urinary incontinence (SUI). Several therapies are available to alleviate GSM symptoms, including hormonal and non-hormonal products. Both microablative fractional CO2 laser and the non-ablative vaginal Er:YAG laser (VEL) induce morphological changes in the vaginal tissues, and data from non-randomized clinical trials suggest that laser therapy can alleviate vaginal dryness and dyspareunia...
