    Notes: Summary.  The ankle is one of the most frequent joint affected by haemophilia, in the second decade of life it can be considered as the most common site for haemophilic arthropathy. The aim of this study is to evaluate the results of 15 surgical interventions of the hindfoot performed on 11 patients. Twenty-seven of 70 male patients suffering from haemophilia were treated for haemophilic arthropathy of the hindfoot. We performed 15 operations on 11 patients with a mean age of 33.5 (range: 10–53) years. The surgical treatment consisted of 15 operations, 12 of which concerned the talocrural joint (six synovectomies, three radiosynoviorthesis, four arthrodeses, one achilles tendon lengthening) and one the talocalcaneonavicular joint (one triplearthrodesis). The arthrodeses of the talocrural joint were undertaken by screw, the triplearthrodesis by clamp fixation. The synovectomies were all late synovectomies and performed by open means. The mean follow-up period was 32.0 (range: 12–84) months. The mean age at surgery was 29.6 (range: 8–51) years. No perioperative complications were registered when adequate replacement therapy was carried out. The consolidation of the arthrodeses was accomplished within 8–12 weeks. All synovectomies stopped or reduced significantly recurrent joint bleeding. With both procedures we achieved pain relief and walking ability improvement. The aim of synovectomy is to reduce bleeding episodes. If synovectomy can halt the progression of the haemophilic arthropathy is controversially discussed, especially when surgery was carried out in the presence of an established arthropathy. If synovectomy fails, the arthrodesis proves to be a good treatment option.

    Notes: Abstract Purpose: Heat shock proteins (hsp) are involved in tumor immunity, and a correlation with survival, occurrence of metastases, and drug resistance has been reported. It was the aim of this study to investigate the expression of heat shock proteins in chondrosarcomas and chondromas. Methods: Hsp expression was investigated immunohistochemically on paraffin-embedded sections of 37 consecutive patients (24 male and 13 female, mean age 48 years) with chondrosarcoma and of ten patients (six male, four female, mean age 36 years) with chondroma. Results: Chondromas showed a positive staining for hsp27 in 100%, for hsp60 in 30%, for hsp72 in 80%, for hsp73 in 80%, and for hsp90 in 90%. In chondrosarcoma a decreased expression was found for hsp27 (62% positive, P 〈 0.05) and hsp72 (43% positive, P 〈 0.05), whereas no significant difference to chondromas was detected in the expression of hsp60 (49% positive), hsp73 and hsp90 (73% and 81% positive, respectively). In addition, hsp72 expression showed a correlation with differentiation of the tumors (P 〈 0.05); the lowest hsp72 expression was found in G3 chondrosarcomas (only 13% positive). No correlation with respect to differentiation was found for the expression of the other hsps. Conclusions: This study shows a different expression of hsps in chondrosarcomas and chondromas. Together with the correlation of hsp72 expression with low differentiation, this finding could lead to new experimental and diagnostic strategies.

    Serum antibodies to heat shock proteins are of no diagnostic value for human kidney allograft rejection (2000)

    Notes: Abstract Because of the prevailing evidence that heat shock proteins (hsp) are involved in transplantation immunology, we investigate in this study the serum levels of anti-hsp60, and anti-hsp70 antibodies in human kidney allograft recipients. We analyzed 67 sera from 20 patients immediately before and 2 weeks after receiving a kidney allograft, and from 27 healthy age-matched controls with an ELISA. Eleven kidneys had normal allograft function, six had a mild rejection episode, all of which could be reversed successfully; three kidneys had to be removed later on because of resistant rejection. Hsp antibody frequency and titres were the same for transplant recipients and for healthy controls. In patients receiving a kidney allograft, no difference in the level of hsp-antibodies before and after transplantation was observed. Additionally, anti-hsp60 and anti-hsp70 antibody titres were found to be independent of the clinical course. These data suggest that the determination of anti-hsp60 and 70 antibody titers are of no diagnostic value for renal allograft rejection.
