BACKGROUND Positron emission tomography (PET) with fluor-18-deoxy-glucose (FDG) is widely used for diagnosing recurrent or metastatic disease in patients with differentiated thyroid cancer (DTC). PURPOSE To assess the diagnostic accuracy of FDG-PET for DTC in patients after ablative therapy. MATERIAL AND METHODS A systematic search was conducted in Medline/PubMed, EMBASE, Cochrane Library, ...
BACKGROUND Multiple modalities have been described for skin rejuvenation, including ablative and nonablative therapies. Because of the prolonged recovery period associated with ablative procedures that injure the epidermis, nonablative skin treatments have grown increasingly popular. Various laser- and light-based systems have been designed or applied for promoting skin remodeling without damag...
Stereotactic ablative radiotherapy is being increasingly adopted in the treatment of lung tumors. The use of proton beam therapy can further reduce dose to normal structures. However, uncertainty exists in proton-based treatment plans, including range uncertainties, large sensitivity to position uncertainty, and calculation of dose deposition in heterogeneous areas. This study investigated the ...
BACKGROUND The use of CO2 or conventional erbium laser ablation or more recent nonablative laser photothermolysis for skin rejuvenation is associated with significant disadvantages. OBJECTIVE The objective was to assess the efficacy of the erbium:YAG laser (2,940 nm) using the "ablative" fractional resurfacing mode to improve photodamaged skin. METHODS A total of 28 patients, 27 women and 1...
A simple procedure is developed to determine the Froude number Fr, the effective power index for thermal conduction n, the ablation-front thickness L0 , the ablation velocity Va , and the acceleration g of laser-accelerated ablation fronts. These parameters are determined by fitting the density and pressure profiles obtained from one-dimensional numerical simulations with the analytic isobaric ...
BACKGROUND Open thyroidectomy is conventionally performed at the anterior side of neck, which is a body part with a comparatively great degree of open exposure; due to this, postoperative scarring may cause distress in patients. We aimed to compare the effects of ablative and nonablative fractional laser treatments on thyroidectomy scars. We examined medical records in a retrospective manner an...
Photodynamic Therapy with Ablative Carbon Dioxide Fractional Laser in Treatment of Actinic Keratosis
BACKGROUND Recently, photodynamic therapy (PDT) has been shown to be an effective first-line treatment for actinic keratosis (AK). However, a major limitation of PDT is the long incubation time required to allow penetration of the photosensitizer. OBJECTIVE The aim of this study was to assess if pretreatment with an ablative carbon dioxide (CO2) fractional laser can reduce the incubation time...
Percutaneous ablative methods guided by imaging techniques are considered nowadays curative treatment for early HCC in patients who are not candidates for liver transplantation and surgical resection. The final goal of all ablative treatments is to achieve complete destruction of neoplastic tissue by disruption of tumor vascularity. The best way to demonstrate the efficacy of any ablative metho...
