INTRODUCTION Fractional ablative and non-ablative lasers have gained popularity in the treatment of acne scars and rhytids due to their efficacy and improved tolerability. Plasma and radio frequency (RF) have also emerged as methods for ablative or non-ablative energy delivery. We report preliminary experience with a novel fractional micro-plasma RF device for the treatment of facial acne scars...

BACKGROUND Limited data describe the prognosis after stereotactic ablative radiotherapy for lung metastases arising from colorectal cancer. Thus, we evaluated treatment outcomes of stereotactic ablative radiotherapy for those patients. METHODS The study involved patients received stereotactic ablative radiotherapy for one to three lung metastases arising from colorectal cancer at a single ins...

Abstract. The method for increasing the shearing strength of adhesive joints in plastics was investigated. This uses laser micropatterning different construction materials to extend surfaces. In investigations, Polyethylene Terephthalate (PET) used. TruMicro 5325c ultra-short pulse (picosecond pulse) and SCANLAB GALVO scanning head applied research enable ablative removal material without heat-...

BACKGROUND AND AIMS Extracted-overlay fusion imaging is a novel computed tomography/magnetic resonance-ultrasonography (CT/MR-US) imaging technique in which a target tumor with a virtual ablative margin is extracted from CT/MR volume data and synchronously overlaid on US images. We investigated the applicability of the technique to intraoperative evaluation of radiofrequency ablation (RFA) for ...

The goal of this project is to use through an intelligent, multimedia computer tutor to increase students’ interest in mathematics and their confidence in their ability to learn mathematics. Based on its student model, WhaleWatch selects problems of appropriate difficulty and provides help and instruction as needed. We present the results of a series of two studies. The first study showed that ...

BACKGROUND The purpose of this study was to evaluate the efficacy of combined local hyperthermia and intravesical mitomycin-C (MMC) in a selected group of patients with intermediate or high-risk recurrent transitional cell carcinoma (TCC) of bladder. PATIENTS AND METHODS Forty-seven patients with multiple or recurrent Ta or T1 TCC of the bladder were treated with intravesical MMC and local hy...

In the wake of deep brain stimulation (DBS) development, ablative neurosurgical procedures are seeing a comeback, although they had been discredited and nearly completely abandoned in the 1970s because of their unethical practice. Modern stereotactic ablative procedures as thermal or radiofrequency ablation, and particularly radiosurgery (e.g., Gamma Knife) are much safer than the historical pr...

The list of indications for which Variable Square Pulse (VSP) Er:YAG laser systems can be used is continuously expanding. For example, ablative fractional resurfacing treatments performed with the VSP Er:YAG laser have good clinical outcomes and significantly shorter recovery times and adverse effects compared with traditional ablative laser skin resurfacing. Recently, an Er:YAG laser operating...

In recent decades, there has been a revolution in energy-based treatment options for skin scarring, rejuvenation, and tightening. One of the most promising developments has been the introduction of fractional photothermolysis, developed by Anderson and Manstein in 2004. Fractionated systems deliver laser energy in a grid-like pattern, creating microscopic columns of ablative and/or coagulative ...

BACKGROUND Skin compromised by traumatic scars and contractures can manifest decreased resistance to shearing and other forces, while increased tension and skin fragility contribute to chronic erosions and ulcerations. Chronic wounds possess inflammatory mediator profiles and other characteristics, such as the presence of biofilms, that can inhibit healing. OBSERVATIONS Three patients with mu...
