Significance of 18F-fluorocholine PET/CT positive pulmonary lesions in prostate cancer patients.

AIM: To assess the frequency and the significance of incidental pulmonary lesions with 18F-fluorocholine (18F-FCH) PET/CT in prostate cancer (PCa) patients. PATIENTS, METHODS: 225 consecutive PCa patients referred for 18F-FCH PET/CT (median age 68 years) were retrospectively evaluated for the presence of lesions in the lungs: 173 referred for restaging and 52 for initial staging regarding their high risk of extra prostatic extension. The final diagnosis was based on histopathological or on clinical and radiological follow-up. RESULTS: 13 patients had 18F-FCH positive pulmonary and 8 patients malignant lesions: 5 patients (38%) had a primary lung cancer (2 squamous cell carcinomas, 1 papillary adenocarcinoma, 1 typical pulmonary carcinoid, 1 bronchioloalveolar carcinoma) and 3 patients (23%) PCa metastases. Benign lesions were found in 5 subjects (38%). SUVmax and maximum diameter were neither significantly different in primary and metastatic tumors nor between malignant and benign lesions. CONCLUSIONS: Although our results suggest that incidental uptake in the lungs in PCa patients are nonspecific, their detection may have a significant impact on patient management knowing that more than 60% represent malignant disease.

[Single teeth on Brånemark fixtures. A new esthetic approach. Presentation of a clinical case]. / Dents unitaires sur fixtures de Brånemark. Proposition d'une nouvelle approche esthetique. Presentation d'un cas clinique.

The reliability of the Brånemark implant system has been well documented. In addition, the technique has been employed in the anterior portion of the mouth with good cosmetic results. Fundamental to the success of these procedures is the multidisciplinary approach. The "Drilling Guide" is the outcome of an intimate relationship between members of the therapeutic team, this allows for the control of all parameters of aesthetics. The preparation of the prosthetic cradle by selecting splaying and eversion is presented as a new approach. The impression method is atraumatic and employs personalized unitary transfers. This leads to the required emergence profile and guarantees the optimum aesthetic result.

[Dental implants and bone grafts]. / Implants dentaires et greffes osseuses.

The reconstruction of an edentulous maxilla with bone graft is not a challenge. It is considered when the remaining bone cannot provide a firm anchorage for implants. The grafts are harvested from the ilium, the chin or the cranial vault. According to the case, the implants are placed either simultaneously or 6 months later after control with C.T. Scan. They are uncovered after another 6 month period, as in the usual procedure, and osseointegration is checked. The percentage of success on 24 operated cases seems at least equal to the regular cases without bone graft. Longer follow-up is needed for reliable statistics.
