A retrospective study of temporomandibular joint ankylosis secondary to surgical treatment of mandibular condylar fractures.

We investigated the incidence of ankylosis of the temporomandibular joint (TMJ) after open operations for fractures of the mandibular condyle, and analysed possible risk factors in a total of 385 patients with 492 condylar fractures who had been operated on in our department from 2001 to 2010. Sixteen patients developed postoperative ankylosis of the TMJ with 26 joints (5%) affected during a follow-up of 6 months-10 years. Of the 492 condylar fractures, the most common ones that were associated with postoperative ankylosis were those of the condylar head (20/248), followed by the condylar neck (6/193).

[Interferon-gamma decreases the adhesiveness and invasiveness of prostate cancer cells].

Objective: To study the effects of interferon-gamma (IFN-gamma) on the adhesiveness and invasiveness of prostate cancer cells.

Methods: We determined the effect of IFN-gamma on the adhesiveness of prostate cancer cell lines LNCaP and PC-3 by treating the plate with fibronectin and laminin, on the invasiveness of prostate cancer cells into the artificial basal membrane consisting of Matrigel and fibronectin using the Transwell chamber, and on the expression of annexin-2 in these cells by Western blot.

Results: The adhesion rates of prostate cancer cell lines LNCaP and PC-3 were 21% and 23% in the IFN-gamma treatment group, significantly lower than 46% and 40% in the untreated group (P < 0.
