[Reimplantation of a non-functioning lung. Report of a case].

The authors present the case of a patient with a carcinoid tumor of the left main bronchus. Conservative surgery by sleeve resection without pulmonary resection was performed. The underlying lung which was considered to be nonfunctioning during pre-operative evaluations, completely recovered within a year following surgery.

[Non-cemented reimplantation of failed hip prosthesis].

After reviewing their series of prosthetic revisions and comparing it with other reports in literature, the authors reassess, where possible, classic conservative intervention as well as the indications for cemented prostheses given the poor long-term reliability of the bone-cement interface. The authors emphasize the always more frequent incidence of prosthetic loosening and the resulting need for surgical revision, especially in patients who were under 65 years of age at the time of primary prosthetic replacement. Finally, the authors present their clinical and surgical experience in revision using cementless implants, which they prefer in this type of operation.

Arthroprosthetic reimplantation with bioceramics.

The study analyzes the results obtained in 50 cases of arthroprosthetic substitution surgery performed as a result of "aseptic detachment of the implant"; it involves a consecutive series of operations performed between 1979 and 1983. In all of the cases ceramic-ceramic cemented prostheses were implanted. The results, which were generally satisfactory, confirmed the excellent properties of alumina (low wear, elevated tolerance).

Growth-plate chondrocyte cultures for reimplantation into growth-plate defects in sheep. Characterization of cultures.

Damage to epiphyseal growth plates due to fracture, trauma, or infection can lead to invasion of bone across the cartilage and localized arrest of long-bone growth. The implantation of a viable de novo cartilage plug into such defects may provide the appropriate cartilage presence necessary to inhibit the initial formation of bony bridges across the epiphysis and so maintain the growth potential. De novo cartilage plugs were prepared from ovine growth plates by culturing isolated epiphyseal chondrocytes from fetal lambs. After 14 days of culture, these de novo cartilage discs were composed of chondroitin sulfate, a small amount (5%) of dermatan sulfate, and cartilage-specific collagen. The cellular morphology and the histochemistry resembled resting zones of normal growth-plate cartilage. Those de novo cartilage discs, which had been embedded in gelled Type I collagen, retained their morphology and could be easily manipulated. On the other hand, Type II collagen and a polyuronic acid gauze (Surgicel) were not satisfactory substrates to facilitate subsequent transplantation into growth-plate defects. The use of 5-carboxyfluorescein diacetate succinimidyl ester (CSFE) throughout the cultures of epiphyseal chondrocytes or prolonged incorporation of [3H]-thymidine appeared to label the cells with useful markers for following their fate subsequent to implantation in vivo.

[The prognostic assessment of dental reimplantations and autotransplants. Clinico-statistical studies].

The identification of prognostic factors which influence the long-term results of dental retransplantation and autotransplantation is one of the main aims of clinical research whose principal scope is remove or alter those factors which have a negative influence on outcome, and to identify the causes of failure and areas for improvement. The paper reports the most significant results of a clinical survey which was carried out on 135 patients who had undergone retransplantation and/or autotransplantation and were then followed for 8 years.
