Abstract

In the modern world, many cities make use of state-of-the-art technologies for a diversity of applications. A field with very specific needs is the electric power system that deals with both large entities that govern themselves (grid operators) and the citizens. For both and all actors in between, there is an increased need for information. Steps to provide these data are always taken and several initiatives are ongoing across the world to equip residential users with last generation smart meters. However, a full deployment is still not possible. Considering this aspect, the authors propose KPIs for the specific situation when some information is available from the meters and other sources, but some is not. The study case is based on a residential area occupied mainly by university students and after an extensive measurement campaign the results have been studied and analysis methods proposed.

Abstract

Introduction. Squamous cell carcinoma is the second as frequency in malignant tumors of the skin, representing 20% of this type of cancer. Inferior lip squamous carcinoma is most frequent, of 94%, because the trauma, sunburns, smoke and radiations are more frequent. Metastasis at distance in the area with chronic osteomyelitis is a rare situation. Material and method. A 78-year-old male, treated for inferior lip carcinoma, without any oncological treatment, was admitted in our clinic for a leg tumor on the anterior part, developed over a scar after osteomyelitis treated in the adolescence. The tumor growth was quick. We decided the treatment plan from the point of view of a multidisciplinary approach, plastic surgeon-orthopedistoncologist- dermatologist. A biopsy from the extraosseous tumor was performed and after the histological confirmation, the resection of the tumor block was made. For the confirmation of the bone invasion, we had to repeat the immunohistochemistry twice because the first result was negative. Until the final decision, the patient had an external fixation on the leg. A large tissue appeared on the area of resection, the aspect being suggestive for granulation. Amputation was decided after the complementary investigations and another biopsy from the granulation tissue. Results and conclusions. Squamous cell carcinoma of the lip needs prophylactic laterocervical ganglia resection for limiting metastasis.
