Deep and continuous palliative sedation (terminal sedation): clinical-ethical and philosophical aspects.
Terminal sedation continues to fuel debate. When confronted with a patient for whom terminal sedation is considered a possible treatment option, decision making can be difficult. In this paper we focus on the clinical-ethical issues, with an aim to provide clinicians with ways of framing the issue from an ethical point of view. ⋯ Accordingly, in the latter part of this paper we draw briefly on selected philosophical positions to elucidate this question. A doctor's belief of what it means to be a "person" might well affect their actions. For example, if a doctor believes terminal sedation involves the destruction of the person, they might not be willing to proceed with it.

ReviewImaging bone metastases in breast cancer: techniques and recommendations for diagnosis.
Bone is the most common site of distant metastases from breast carcinoma. The presence of bone metastases affects a patient's prognosis, quality of life, and the planning of their treatment. We discuss recent innovations in bone imaging and present algorithms, based on the strengths and weaknesses of each technique, to facilitate the most successful and cost-effective choice of imaging studies for the detection of osseous metastases. ⋯ MRI or PET-CT can be considered for cases of abnormal radionuclide uptake that are not addressed by radiography. Osseous metastases can lead to emergent situations, such as spinal-cord compression or impending fracture of a weight-bearing bone, and imaging guidelines are essential for early detection and initiation of appropriate therapy. The imaging method used in non-emergent situations, such as assessment of the ribs, sternum, pelvis, hips, and joints, should be guided by the strengths and limitations of each technique.
