When mastectomy becomes inevitable: The nipple-sparing approach
ABSTRACT The preservation of the nipple areola complex (NAC) could improve the quality of life in cases of mastectomy. A novel radiosurgical treatment combining subcutaneous mastectomy with intraoperative radiotherapy is proposed. Three hundred nipple-sparing mastectomies (NSM) were performed. Invasive (58%) and in situ (42%) carcinomas were included. Clinical complications, aesthetic results, oncological and psychological results were recorded. The NAC necrosed totally in 10 cases and partially in 29 and it was removed in 12. Nine infections (3%) were observed and 10 prostheses removed. Good results were rated by 82.3% of the patients and by 84.8% of the surgeons. In 7.5% a radiodystrophy was observed. The sensitivity of the NAC recovered partially in 48%. Two local recurrences occurred outside the radiated field. Overall, we observed three metastases and no deaths. Sixty-eight of the patients were satisfied with their reconstructed breast and 85.5% were satisfied having preserved the NAC.

Conference Paper: VLSI bit-level systolic array for radar front-end signal processing[Show abstract] [Hide abstract]
ABSTRACT: A very-high-speed radar front-end signal processing CMOS VLSI chip-set using a fully efficient bit-level systolic array architecture has been developed by MIT Lincoln Laboratory. The chip-set performs baseband quadrature sampling, channel equalization, pulse compression, and digital beamforming. The highly pipelined fully efficient bit-level systolic architecture and the highly optimized scalable CMOS VLSI cell library design give the chip-set extremely high performance. The chip-set uses an efficient 4:1 down-sampling baseband quadrature sampling architecture with reduced computational requirement. The chip-set and the cell library have potential in a variety of applications such as communications and medical imagingSignals, Systems and Computers, 1994. 1994 Conference Record of the Twenty-Eighth Asilomar Conference on; 01/1994
