BACKGROUND Incisional hernias occur frequently after abdominal surgery and can cause serious complications. The choice of a type of open operative repair is controversial. Determining the type of open operative repair is controversial, as the recurrence rate may be as high as 54%. OBJECTIVES To identify the best available open operative techniques for incisional hernias. SEARCH STRATEGY Ele...

A fundamental problem in many areas of classification, and particularly in biology, is the reconstruction of a leaf-labeled tree from just a subset of its induced subtrees. Without loss of generality, we may assume that these induced subtrees all have precisely four leaves. Of particular interest is the question of determining whether a collection of quartet subtrees uniquely defines a parent t...

BACKGROUND We report our results after 100 urethroplasties for the treatment of urethral stricture both at the bulbar and penile urethra, using different techniques. METHODS 100 patients with the diagnosis of anterior urethral stricture, that were submitted for urethroplasty in the period 1997-2007. Of them, 57 treated by end to end urethroplasty. 4 patients underwent augmented free graft ana...

The aim of the present retrospective chart review was to determine the relationship between nonvascularized osseous graft remodeling and the three-dimensional (3D) features of grafts and recipient sites, the anatomical recipient regions and different graft sources. 32 iliac crest or chin grafts were onlay-positioned in the mandible or maxilla of 14 patients. CT scans, taken before implant posit...

This study evaluated the effect of retentive areas on onlay preparations on the dimensional alterations in condensation and addition silicone materials. A standard model with an onlay preparation was made. Each impression material was used through the double or simultaneous impression technique (n=25), resulting in a hundred impressions of the same model. Impressions were poured with type IV de...

Main Text: The traditional “patching” approach to managing software vulnerabilities and cybersecurity risk has been less effective than desired. In theory, once a vulnerability is discovered, software patches should be quickly developed and released by producers and then expeditiously applied by users. Successful completion of this process would help to maintain secure systems. However, what ha...
