Q: 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.

Q: Abstract: Boerhaave's syndrome represents a diagnostic dilemma for the emergency physician. The prognosis of this truly life-threatening emergency is darkened by any significant diagnostic delay. Unfortunately, classic or expected symptoms and signs are frequently absent at presentation, a circumstance that leads to frequent misdiagnosis. Two cases of Boerhaave's syndrome with "atypical" clinical presentations are reviewed and discussed. It is clear that Boerhaave's syndrome should always be suspected in the evaluation of any sudden chest, abdominal, or back pain associated with emesis. However, emphasis should be placed on the fact that this entity may occur without emesis. The chest radiograph is the most helpful diagnostic aid. Undoubtedly, maintenance of a high degree of suspicion by the emergency physician for Boerhaave's syndrome will lead consistently to earlier diagnosis, and subsequent aggressive intervention should result in considerable reduction in rates of both morbidity and mortality.

Q: Abstract: Although an action of corticosteroids to inhibit glucose transport is well known, the mechanism by which this is brought about has been unclear. Some evidence has suggested an action on insulin receptors, but a postbinding or postreceptor effect has also been reported. As hydrogen peroxide acts at a postbinding site to stimulate glucose transport, studies were carried out in 3T3-L1 fibroblasts to determine whether corticosteroids would inhibit hydrogen peroxide-induced glucose transport. In this cell type, both insulin and hydrogen peroxide produced a marked increase in glucose transport after a 30-min incubation. The increase produced by hydrogen peroxide, as well as insulin, was inhibited by previous incubation of the cells with dexamethasone. These findings give further support to the conclusion that dexamethasone has effects on glucose transport at a postbinding site. As changes in membrane lipids influence the movement and/or activity of glucose transporters, and dexamethasone alters membrane lipids, dexamethasone-induced changes in the lipids of the plasma membrane may be important in the mediation of the steroid effect upon glucose transport.
