We study the computational complexity of computing a manipulation of a two stage voting rule. An example of a two stage voting rule is Black’s procedure. The first stage of Black’s procedure selects the Condorcet winner if they exist, otherwise the second stage selects the Borda winner. In general, we argue that there is no connection between the computational complexity of manipulating the two...

Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) has recently been introduced as a new surgical technique to increase future liver remnant in patients with marginal liver volume contemplating major liver resection. We herein present two cases. Case 1: a 68-year-old male patient with colorectal liver metastasis was referred to our department. The future liver r...

OBJECTIVE To demonstrate the efficacy of intact canal wall procedure coupled with a second-stage exploration for the treatment of cholesteatoma. DESIGN Retrospective case study of patients with cholesteatomas treated with staged surgical extirpation. A minimum of 6 months' postoperative follow-up time was required for inclusion into the study. SETTING Tertiary academic referral center. Pati...

this paper presents an analytic procedure for the value added to different production levels with different policy options. the approach is stochastic and thus provides a framework for informed decision-making on productivity growth under uncertainty conditions. the model was applied to data collected from a firm and re-sults recommend that the firm should redevelop if in diversification and sy...

BACKGROUND AND PURPOSE Mechanically failed internal fixation following hip fracture is often treated by salvage arthroplasty. If deep wound infection is present, a 2-stage procedure is often used. We have used a 1-stage procedure in infected cases, and we now report the outcome. PATIENTS AND METHODS We reviewed 16 cases of deep wound infection after mechanically failed hip fracture fixation, ...

With the improvement in outcomes and modern prosthesis design, total knee arthroplasty (TKA) has now become a commonly performed surgery. It is postulated that a total of 2-5% of the primary and revision TKA becomes infected every year, requiring a revision procedure which to date is the conventional two-stage revision. The diagnosis and treatment of these periprosthetic infections is a major a...
