CONTEXT: Xanthelasma palpebrarum is the most common form of xanthomas. Albeit a benign entity, it is cosmetically disturbing and a frequently recurring dermatologic referral. Although the classical treatment option remains surgical excision, alternatively, chemical cauterization, cryosurgery and electrofulguration have all been tried in the past with mixed results. The use of laser systems such as carbon dioxide laser, Erb:YAG laser, Q-switched Nd:YAG laser, diode laser, pulsed dye laser and KTP laser have become popular in the treatment of these lesions...

SESSION TITLE: Bronchology/Interventional Global Case ReportsSESSION TYPE: Global Case ReportPRESENTED ON: Tuesday, October 28, 2014 at 01:30 PM - 02:30 PMINTRODUCTION: Kaposi sarcoma (KS) remains the most common AIDS-associated neoplasm. Endobronchial KS typically appears as slightly raised, violaceous lesions in the sub-mucosa of the endobronchial wall and is usually associated with similar mucocutaneous lesions elsewhere on the body. We herein describe an unusual case of KS presenting as an isolated obstructing endobronchial tumor that was effectively resected using electrocautery snare and argon plasma coagulation (APC)...

Topical application of therapeutic agents has been a mainstay in Dermatology for the treatment of skin disorders but is not commonly used for systemic delivery. For a topically applied agent to reach distant body sites it must first overcome the barrier function of the skin and then penetrate into deeper structures before reaching the systemic circulation. This has limited the use of topically applied agents to those having specific charge, solubility and size restrictions. Pretreatment of the skin with ablative fractional laser appears to enhance the uptake of some topically applied drugs but the ability to effectively deliver agents to distant sites is largely unproven...

Gunpowder traumatic tattoo and foreign bodies in the skin secondary to explosions or gunshots need to be treated within 72 h if possible to achieve good aesthetic results. Hypertrophic scars can be treated by skin resurfacing using the Erb-YAG laser or the CO₂ laser, while traumatic tattoos can be removed with the Q-switched rubin laser.

BACKGROUND: The aim of this study was to evaluate the effect of 2nd generation argon plasma coagulation (VIO APC) with respect to the tissue destruction capacity, and to compare it with standard APC and Nd:YAG laser. METHODS: 2nd generation APC (VIO APC2, Erbe, Germany), standard APC (APC 300/Erbotom ICC 200, Erbe) and Nd:YAG laser (KTP/YAG XP 800; Laserscope, San Jose, California) were applied in 35 porcine livers. Using APC, power settings (30-120 W), application time (2 and 5 sec) and gas flow (1 and 2 l/min) were varied...

BACKGROUND: The surgical therapy of glaucoma aims at an effective IOP lowering as well as at a long-term effect with few complications. The previous gold standard of combined surgery consisted of cataract surgery and trabeculectomy. The combination of cataract surgery and Erb:YAG goniotomy might be an alternative. METHODS AND PATIENTS: A total of 17 eyes were treated with combined Erb:YAG goniotomy. The control group underwent combined trabeculectomy and consisted of 23 eyes...

BACKGROUND: The aim of this study was to analyze safety and efficacy of a new high power argon plasma coagulation system in the upper gastrointestinal tract. METHODS: Data of 215 patients treated with a high power argon plasma coagulation system in the upper gastrointestinal tract 04/2003-01/2004, using a VIO APC device (VIO 300 D with APC 2; Erbe Elektromedizin, Tübingen, Germany; pulsed argon plasma coagulation, 20-120 W), were reviewed and analyzed. Indications were as follows: additive ablation therapy in curative treatment of early Barrett's cancer (122 patients); palliative treatment of oesophageal cancer (n=27); gastric adenoma/carcinoma (n=19); Zenker's diverticulum (n=8); and other...

BACKGROUND: 5-aminolaevulinic acid (ALA) is used as a protoporphyrin IX-precursor for the photodynamic therapy of superficial skin cancer and cutaneous metastases of internal malignancies. However, the permeability of hydrophilic ALA across the skin is very low. OBJECTIVES AND METHODS: The objective of this study was to optimize and enhance the in vitro skin permeation of ALA by two resurfacing techniques: erbium:yttrium-aluminium-garnet (Erb:YAG) laser and microdermabrasion...

BACKGROUND: Recurrent hemorrhage in patients with severe radiation proctitis is very common. It is often refractory to medical therapy. Endoscopic and surgical treatment may be required when conservative medical therapy fails. The aim of this study was to assess the therapeutic results of the Argon Plasma Coagulator (APC) (ERBE USA, Inc., Marietta, GA, USA) application in patients with radiation proctitis-induced hemorrhage. METHODS: Forty patients with radiation-induced proctitis causing severe bleeding, who had failed conservative medical management were treated endoscopically...

BACKGROUND AND OBJECTIVE: Rhinophyma is a benign, disfiguring disorder of the nose which presents the end stage of acne rosacea, and can also occasionally result in nasal airway obstruction. We describe the first series of patients treated with Erbium laser. STUDY DESIGN/MATERIALS AND METHODS: Severe-to-moderate rhinophyma in six patients were treated at our institution between 1995 and 1996, using the Erbium:YAG (Erb:YAG) laser. RESULTS: All patients achieved marked cosmetic improvement, with no complications...

Ho:YAG, Nd:YAG, and Erb:YAG laser ablation of Polymethylmethacrylate (PMMA) was investigated under in vitro and simulated clinical conditions. Ablation rates were measured for all lasers and after ablation, macroscopic and microscopic appearance of the ablation site was investigated. The mean ablation rates of the Erb:YAG, Ho:YAG, and Nd:YAG laser increased from 8 microns per pulse at 100 mJ to 44 microns per pulse at 300 mJ from 100 microns per pulse at 200 mJ to 222 microns per pulse at 800 mJ and from 28 microns per pulse at 100 mJ to 189 microns per pulse at 800 mJ, respectively...

Sixty-nine male Sprague Dawley rats were divided into three groups of 23 animals each and osteotomies were performed in group 1 with a power saw, in group 2 with the Erb:Yag laser, and in group 3 with the Hol:YAG laser. Two animals of each group were sacrificed 1 week, 4, 8, and 12 weeks after operation for histologic investigation, and five animals of each group at 4, 8, and 12 weeks after osteotomy for torque testing. Anterior-posterior (AP) radiographs were taken at the same time points and investigated for callus formation and development of pseudoarthrosis...

The bone ablation characteristics of five infrared lasers, including three pulsed lasers (Nd:YAG, lambda = 1,064 micron; Hol:YSGG, lambda = 2.10 micron; and Erb:YAG, lambda = 2.94 micron) and two continuous-wave lasers (Nd:YAG, lambda = 1.064 micron; and CO2, lambda = 10.6 micron), were studied. All laser ablations were performed in vitro, using moist, freshly dissected calvarium of guinea pig skulls. Quantitative etch rates of the three pulsed lasers were calculated. Light microscopy of histologic sections of ablated bone revealed a zone of tissue damage of 10 to 15 micron adjacent to the lesion edge in the case of the pulsed Nd:YAG and the Erb:YAG lasers, from 20 to 90 micron zone of tissue damage for bone ablated by the Hol:YSGG laser, and 60 to 135 micron zone of tissue damage in the case of the two continuous-wave lasers...

In 32 rabbits, lesions of comparable depths were created in the oral mucosa using a Nd-YAG laser (Medilas II, 1.06 microns, MBB Co., Munich) and a cryosurgery unit (Kryo-S, Erbe Co., Hannover). Histologic specimens were examined between 1 h and up to 8 weeks following operation. The laser lesion was restricted horizontally to the laser-exposed area; the full extent of the lesion could already be seen after 1 day. Cryosurgical lesions showed their maximum extent 3 days following treatment. Wound healing processes following laser application, were accelerated compared to cryosurgical procedure...

Erb:YAG and Hol:YAG laser ablation rates of fibrocartilage and nucleus pulposus were measured in vitro simulating clinical conditions. After ablation macroscopic and microscopic appearance of the ablation site was investigated. Hol:YAG and Erb:YAG laser mean ablation rates increased almost linearly with rising energies, showing higher total ablation rates for the Hol:YAG laser due to its higher achievable energy density. At comparable energy densities the Erb:YAG laser appears to be more effective with respect to the corresponding ablation rates...
