Phantom breast syndrome (PBS) developed in 11 out of 31 (35.5%) consecutive young women, who had undergone mastectomy for breast cancer. Six to 21 months after operation the patients were asked to take part in a follow-up investigation in which physical sequelae, social condition, and psychological reactions were assessed and related to the presence of PBS. There was no correlation between PBS and postsurgical physical sequelae, those who had received adjuvant radiotherapy, or the side on which mastectomy was performed. ⋯ However, the predominance did not reach a statistically significant level. Sexual identity, anxiety, affective disorder or changes in close family relationships did not reveal any distinct pattern. In our opinion, the appearance of PBS should be seen in relation to complex psychological reactions to the mastectomy.

Renal cortical and medullary tissue oxygen tension, systemic oxygen supply as well as central and renal hemodynamics were investigated in dogs during graded hemorrhage and subsequent reinfusion of shed blood. The measurements of tissue gas tension were carried out by means of implanted Silastic tubes. The baseline renal cortical PO2 was 35 mmHg and the corresponding medullary PO2 25 mmHg. ⋯ Arterial blood PO2 was normal throughout the study. Renal venous PO2 fell during the deepest shock but consistently exceeded the corresponding tissue PO2 levels. It is concluded that hemorrhagic hypotension impaired tissue oxygenation of both cortex and medulla, the effect being greatest in the cortex.
