Ultrasound-guided core-needle biopsy has high sensitivity in the diagnosis of breast cancer. The present study is aimed at detailing the main steps of such procedure, including indications, advantages, limitations, follow-up and description of the technique, besides presenting a checklist including the critical steps required for an appropriate practice of the technique. In the recent years, an increasing number of patients have required breast biopsy, indicating the necessity of a proportional increase in the number of skilled professionals to carry out the procedures and histological diagnoses. A multidisciplinary approach involving the tripod clinical practice-radiology-pathology is responsible for the highest rate of accuracy of the technique and must always be adopted.

Objective: This work aims to link the technological advances (cochlear implant) in prosthetic equipment for the deaf to their impact on voice and speech in profound hearing loss.Method: Thirty-three patients between 6 and 30 years old with bilateral profound sensorineural congenital hearing loss, with cochlear implants. The recorded patient voices have been digitally processed with an Acoustic Analysis of Voice and Speech Program ANAGRAF and have also been analyzed and registered by the segmental and suprasegmentals features of voice and speech.
