    Aquacel Surgical Dressing Reduces the Rate of Acute PJI Following Total Joint Arthroplasty: A Case-Control Study.

    An effort to prevent PJI has led to the development of antimicrobial dressings that support wound healing. We sought to determine whether Aquacel Surgical dressing independently reduces the rate of acute PJI following TJA. A single institution retrospective chart review of 903 consecutive cases who received the Aquacel Surgical dressing and 875 consecutive cases who received standard gauze dressing was conducted to determine the incidence of acute PJI (within 3months). The incidence of acute PJI is 0.44% in the Aquacel dressing group compared to 1.7% in the standard gauze dressing group (P=0.005). Multivariate analysis revealed that use of Aquacel dressing was an independent risk factor for reduction of PJI (odds ratio of 0.165, 95% confidence interval: 0.051-0.533). Aquacel Surgical dressing significantly reduces the incidence of acute PJI

    An evaluation of the effectiveness of a reproductive health education program for nonmedical students in Iran: A quasi-experimental pre-test, post-test research

    Background: Young people age 10 - 25 are an important population to evaluate the female youth educational program essential to the prevention of issues related to reproductive health. Objectives: This study evaluated the effectiveness of the education program for improving university student�s reproductive health. Patients and Methods: This quantitative study was conducted in Iran from July 2014 to March 2015. The questionnaire addressed socio-demographic features, knowledge of reproductive problems, and attitudes. Program effectiveness was examined using a quasi-experimental research design with pre-intervention and post-intervention. Data from questionnaires was collected preintervention and post-intervention from 150 female students. Results: In this study, results showed that an intervention and education program had a significant effect on several issues related to reproductive health. Most participants stressed the need to provide reproductive health services for young girls. Conclusions: The results of this study suggest that the reproductive health education program improved the students� knowledge and attitudes about sexuality and decision-making after the program and that these educational programs are important for youths. © 2016, Shiraz University of Medical Sciences

    New Attractors, Entropy Function and Black Hole Partition Function

    By making use of the entropy function formalism we study the generalized attractor equations in the four dimensional N=2 supergravity in presence of higher order corrections. This result might be used to understand a possible ensemble one could associate to an extremal black hole.Comment: 20 pages, latex file, V2: minor corrections, typos corrected, Refs added, V3: the version appeared in JHE

    Does ‘excessive’ anticoagulation predispose to periprosthetic infection?

    Background Although persistent drainage and hematoma formation are recognized risk factors for the development of periprosthetic infection, it is not known if excess anticoagulation is a predisposing factor. Methods We conducted a 2 to 1 case-control study with 78 cases who underwent revision for septic failure. The controls underwent the same index procedure but did not develop consequent infection. Patient comorbidities, medications, intraoperative, and postoperative factors were compared. Results Postoperative wound complications including development of hematoma and wound drainage were significant risk factors for periprosthetic infection. A mean international normalized ratio of greater than 1.5 was found to be more prevalent in patients who developed postoperative wound complications and subsequent periprosthetic infection. Conclusions Cautious anticoagulation to prevent hematoma formation and/or wound drainage is critical to prevent periprosthetic infection and its undesirable consequences

    Periprosthetic joint infection: are patients with multiple prosthetic joints at risk?

    Get PDF
    Patients who present with a periprosthetic joint infection in a single joint may have multiple prosthetic joints. The risk of these patients developing a subsequent infection in another prosthetic joint is unknown. Our purposes were (1) to identify the risk of developing a subsequent infection in another prosthetic joint and (2) to describe the time span and organism profile to the second prosthetic infection. We retrospectively identified 55 patients with periprosthetic joint infection who had another prosthetic joint in place at the time of presentation. Of the 55 patients, 11 (20%) developed a periprosthetic joint infection in a second joint. The type of organism was the same as the first infection in 4 (36%) of 11 patients. The time to developing a second infection averaged 2.0 years (range, 0-6.9 years)
