Particulate wear debris osteolysis, acute urinary retention and delirium as late complications of hip arthroplasty.

Intrapelvic mass formation as a result of particulate wear debris induced osteolysis is a recognised late complication of cementless total hip arthroplasty. Clinical presentation typically involves hip and/or leg pain resulting in functional impairment, and obstructive urinary symptoms developing 3-20 years after surgery. An acute confusional state has never been described in this scenario.

Body composition assessed by anthropometry and bioelectric impedance analysis in older persons recovering from cerebrovascular accident.

We investigated body composition in older patients who had experienced a cerebrovascular accident (CVA) and were participating in a recovery program that included physical exercise. We studied 61 persons in two groups. One group consisted of 13 men and 12 women (mean age, 68 years) who were receiving day center care to recover from a CVA that had occurred from six months to one year previously.
