We report a rare case of chronic disseminated histoplasmosis with several ulcerated lesions in the oral cavity in an alcoholic patient without human immunodeficiency virus infection, with no detectable signs and symptoms of systemic disease or extraoral manifestations. Histopathological analysis revealed chronic inflammatory process with granulomas(More)
Melanoma of the oral cavity is a rare malignant disease that is often discovered in an advanced stage; survival time is an average of five years. Oral melanoma makes up from 0.2 to 8 percent of all melanomas. The presentation of this clinical case demonstrates the complexity of clinical and histopathological manifestations and poor prognosis of oral(More)
— This paper presents a new beamforming transmitter, Ultra Wide Band (UWB) pulse generator for contactless radar monitoring applications of vital signals. The system consists of a programmable delay circuit (PDC or τ), UWB pulse generator circuit and an array of Vivaldi planar antennas. Also, a new CMOS PDC controller is developed in order to provide pulse(More)
This paper describes the design, and experimental characterization of cross inductors in a 0.35μm CMOS technology. The Sonnet tools were used to simulate and evaluate the performance of the new inductor structure, whose core has perpendicular crossed segments at the two highest layers available of the technology. Due to this arrangement, the positive as(More)
