The World Health Organization classifies liver cancer among the five types of cancer with highest death rates in the world. Among the current methods available for the treatment of liver cancer, there is the resection of hepatic tissue and the radiofrequency ablation of the tumor. Even though resection presents the best results, only 10% to 15% of the affected patients may eligible for this procedure. On the other hand, the radiofrequency ablation encompasses a larger scope of patients and provides a non-invasive method when compared to resection. There is research with sufficient evidence to allow the transposition of this concept to new technological paradigms, which would yield a more effective ablation process, i.e.: generating enough volumetric necrosis for complete regression of the tumor, leading to a high survival rate of patients. These technological paradigms encompass aspects of operability, innovation and of theoretical framework. In terms of operability, there is the use of better imaging sources to aid the healthcare professional in the positioning of electrodes; in terms of innovation, there are new technologies such as the use of optical fiber microsensors and metallic magnetic nanoparticles to increase the efficiency of the process; in terms of theoretical framework, there is the development of more precise mathematical models that would expand the possibilities of application and increase its effectiveness. These new challenges are new possibilities that may reshape the concept and the use of radiofrequency ablation as it is currently known.

According to the Brazilian Association of Endocrinology and Metabolism, diabetes, or Diabetes Mellitus, is a chronic, autoimmune disease, characterized by the deficiency of insulin production by the body. The problem involves the metabolism of glucose in the blood and can be presented in several ways. The best known types of diabetes are 1 and 2. Beta-cell failure in the pancreas characterizes the first, which affects children and adolescents more often. Type 2 diabetes, whose genetic load is much higher, occurs due to resistance to insulin action, with obesity as one of the main triggering factors. The other forms of diabetes can be manifested by anatomical lesions in the pancreas, due to several toxic aggressions, by infections, chemical compounds, among others. A very common consequence of diabetes it's a formation of skin wounds due to metallic disorders, these wounds can be very aggressive and diminish the quality of life of the patients. Anequipment based on phototherapy associated with a latex blade was developed as an alternative treatment for skin wounds, the equipment works directly on the neoformation of the wounded tissue, accelerating the scarring process at a low cost.
