The broad acceptance of "spot scanning" or "flying spot" excimer lasers in the last decade has enabled the domination of corneal ablative laser surgery over other refractive surgical procedures for the correction of hyperopia, hyperopic and mixed astigmatism. This review outlines the most important reasons why the ablative laser correction of hyperopia, hyperopic and mixed astigmatism for many ...

During the last years, a number of new devices have been developed to improve the dermal and epidermal signs of photo- and chronological skin ageing. There are well-established ablative and non-ablative skin resurfacing options using different lasers and light sources, but side effects have been observed frequently. A recently developed photorejuvenation method using non-thermal stimulation of ...

PURPOSE We describe the use of a hemostatic wax sealant during laparoscopic renal ablative procedures to allow airtight transabdominal access of the treatment probe through a standard 5-mm port. METHODS Following Tru-cut biopsy of the renal mass, Bone Wax was used to occlude the external opening of an established 5-mm laparoscopic port. The cryotherapy or radiofrequency treatment probe was th...

The ablation of atrial fibrillation (AF) is an area of intense research in cardiac electrophysiology. In this review, we discuss the development of catheter-based interventions for AF ablation. We outline the pathophysiologic and anatomic bases for ablative lesion sets and the evolution of various catheter designs for the delivery of radiofrequency (RF), cryothermal, and other ablative energy s...

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 ...
