Abstract: The authors present an in-depth clinical, radiographic, and pathologic analysis of a 62-year-old man with massive bone reabsorption around the proximal femur in a total hip arthroplasty (THA). The THA was revised 13 years after implantation. Thirty millimeters of calcar resorption was noted radiographically. Evidence of stem bending was present on examination of the femoral implant, and marked wear of the acetabular cup was noted. The pathologic evaluation of removed calcar bone and cement revealed a histiocytic mass invading the bone. Intracellular and extracellular polymethylene debris was noted within the invasive mass. Evidence of fragmented methylmethacrylate cement was also present. The bone-cement interface in the excised calcar region contained segments that showed active bone remodelling around the cement without an interposed membrane. It is possible that this case of calcar resorption began with histiocytic activation and recruitment by polyethylene wear debris followed by active bone lysis. The process may be perpetuated by the fragmentation of cement, as motion occurred at the calcar bone-cement interface, and may represent an extreme example of a process occurring in cases of calcar resorption in general.

Abstract: The metabolism of catecholamines (CA) in non-selected patients with chronic renal failure and under hemodialysis (CRFh) was studied by measuring the concentration of plasma free, sulfo- and glucuroconjugated CA, dopamine (DA), norepinephrine (NE), and epinephrine (EPI). Our data demonstrate a statistically significant increase of free DA and free NE concentration in CRFh, while that of free EPI was not different from controls. However a careful scrutiny of 35 individual data suggests that sub-groups of patients with either high normal or low plasma-free NE concentration could exist; this likely heterogeneity could be a good explanation for conflicting conclusions provided by previous reports. Suspecting that conjugated CA might be altered in CRFh, plasma sulfo- and glucuro-conjugated DA, NE and EPI were also measured. We have found a predictable and highly significant increase of sulfo-conjugated CA; plasma concentration of glucuro-conjugated DA and NE in CRFh was not different from controls, while that of glucuro-conjugated EPI was significantly increased. The physiological meaning, if any, of these new observations on conjugated CA cannot be assessed at the moment. The effects of hemodialysis were also investigated. Measurements on the arterial and on the venous line showed highly significant differences for tyrosine, free and sulfo-conjugated CA, and a lack of difference for glucuro-conjugated CA. Thus tyrosine, free and sulfo-conjugated CA were eliminated by the artificial kidney, but not glucuro-conjugated amines.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract: Nucleated cells can resist lysis by and recover from complement attack even after formation of the potentially cytolytic membrane attack complex on the cell surface. We have found that human neutrophils resist complement lysis by the physical removal of membrane attack complexes by both endocytic and exocytic process. The latter mechanism predominates, vesiculation being detectable within 60 sec of initiating the complement cascade. Sixty-five percent of the formed complexes are removed on plasma membrane vesicles, although only 2% of the cell surface is lost. Ultrastructural examination revealed that these vesicles were covered with ring-like "classical" complement lesions. Analysis of these vesicles by gel electrophoresis indicated that C9 was present exclusively in the form of a sodium dodecyl sulfate-resistant, high m.w. complex. In contrast, the 35% of C9 that remained associated with the cells was found to be inaccessible to a C9-specific monoclonal antibody, and was partly degraded, suggesting internalization of the membrane attack complex and proteolysis of some C9 molecules. The molar ratio of C9 to C8 was 12 to 1 on shed vesicles and on recovered cells.
