[Current indications for coral in craniofacial surgery. A 10-year experience].
After a ten year clinical experience of coral implants in Cranio-Facial Surgery, the authors can precise the up to date indications. 55 patients received coral inlays. Two varieties of coral have been used, Goniopora and Polyphylla, demonstrating complementary properties. Filling of bony defects and volumetric increase specially held our attention. Coral may be discussed versus autologous bony grafts in very circumscribed indications.

Modified Benchekroun technique for continent ileal stoma.
The Guzman continent ileal stoma is constructed by a modification of the Benchekroun technique, which is based on the principle of the inkwell and collapse of the inner tube through retrograde filling of the valve. We used this procedure in 7 patients, all of whom are continent. During a followup of 6 months to 2 years no major complications developed. The stoma is easy to construct, has a low risk of evagination because the inner tube is stabilized with sutures and is easy to catheterize. It does not require staples, which reduces the chance of stone or fistula formation. The terminal ileum in continuity with the cecum or an isolated ileal segment can be used.

[Various cases of ossifying fibroma and cranio-maxillofacial fibrous dysplasia].
Rare and of difficult diagnosis, osteofibroma and fibrous dysplasia can occur in different areas of the face and skull. Differential diagnosis is difficult particularly in the isolated forms and need histological confirmation. This will guide their different treatment depending of their nature and localisation. In case of base of skull involvement eyesight must be looked into particularly well.

[Correlation between prostate specific antigen and histopathologic findings in ileum-obturator node dissection].
OBJECTIVE: To determine the correlation between PSA values and the histopathological findings of ileo-obturator node dissection in prostatic cancer. METHODS: We reviewed the data of 51 patients with clinically localized prostatic carcinoma, submitted to ileo-obturator node dissection before definitive treatment of the tumor. The patients were classified into 4 groups according to their previous PSA values: A < 10 ng/ml, B > 10 and < 20 ng/ml, C > 20 and < 50 ng/ml and D < 50 ng/ml. RESULTS: Overall 17.6% of the patients had positive lymph nodes; 9.9% of the patients in group A, 15.4% of the patients in group B, 11.1% of those in group C and 41.7% of those in group D had positive nodes. Using 50 ng/ml as the cut-off point, 10% of those with PSA < 50 ng/ml had positive nodes vs 42.3% of those with PSA > 50 ng/ml, which was statistically significant with the Fischer test. CONCLUSION: Preoperative PSA has a statistically significant correlation with positive nodes, considering 50 ng/ml as the cut-off point. PSA determination in patients that have received no treatment is essential in the diagnosis and evaluation of therapy in prostate cancer.
