Do tissue marker clips after sonographically or stereotactically guided breast biopsy improve follow-up of small breast lesions and localisation of breast cancer after chemotherapy?
Positioning a tissue marker clip in the tumour centre seems to be reasonable after interventional biopsy of breast lesions of 1.0 cm or smaller and before neoadjuvant chemotherapy.
Serum concentration of Mg decreases significantly within the first 24 hours of major lung resection. Although our study didn't demonstrate a relationship between decreases in sMg and the generation of arrhythmias, this link is well established in other fields and thus we support the prophylactic MgSO(4) administration in their prevention in such cases whilst we await further larger studies.
