Traitement par prothèses sur implant de l’édentement postérieur partiel : suivi à long terme d’une étude prospective

Objective: This paper reports on the long-term outcome of patients with Kennedy Class IV partial edentulism treated in the Implant Prosthodontic Unit (IPU) at the University of Toronto, Toronto, Ontario. Methods: The information for this paper was gathered from the charts of the first 30 consecutive, partially edentulous patients treated at the IPU. These patients all had Class IV edentulism and formed part of the original prospective clinical studies that were initiated in 1983. The patients’ dental history suggested maladaptive experiences with traditional removable prostheses or a reluctance to have intact or quasi-intact teeth prepared as retainers for fixed prostheses. Fifteen men and 15 women treated with 94 Brånemark dental implants, supporting 34 prostheses, were followed until June 2000 (25 patients) or until they were lost to follow-up (5 patients). The multiple missing teeth occurred in 19 maxillae and 15 mandibles. Results: The original prosthodontic treatments were intended to result in 33 fixed partial prostheses and 1 overdenture. At the time of this report, 25 patients with 86 implants supporting 31 fixed prostheses and 3 overdentures had been followed for an average of 12 years (range 7–16 years). The overall survival of implants was 92%. The difference between men (94%) and women (89%) was not statistically significant. Conclusions: This report is an interim update on an ongoing long-term prospective study. The results so far demonstratea high survival rate for Brånemark implants supporting tissue-integrated prostheses for the management of anterior partial edentulism.peer-reviewe

Student concerns regarding transition into higher education CS.

This paper discusses a study where 249 students from 18 secondary schools around Scotland who were on the verge of applying to study Computing Science at a higher education institution were surveyed on their concerns about the upcoming transition. Preliminary conclusions from this work point to the fact that this transition process is one that seems to evolve with the student as they progress through their education, and as such, should be treated differently at various stages within that process

Control strategies for late blight in organic potato production

This report was presented at the UK Organic Research 2002 Conference. Protective copper fungicides are currently used to control late blight in most organic production systems, but approval for their use in organic farming will be revoked in 2002. Evidence suggests that organic potato production will not be reliably economic in the absence of Cu. Current controls for late blight are reviewed including: variety selection/breeding for blight resistance, diversification strategies, agronomic strategies for the management of late blight, and alternative treatments to Cu-fungicides

Identification of targets for quality improvement in antimicrobial prescribing : the web-based ESAC Point Prevalence Survey 2009

Objectives: Since electronic prescribing is limited to few hospitals, point prevalence surveys, such as the standardized European Surveillance of Antimicrobial Consumption point prevalence survey (ESAC PPS), are an alternative tool for monitoring prescribing and helping to identify performance indicators and prescribing trends. The main objective of this study was to identify and assess targets for quality improvement. Methods: Each hospital had to carry out the survey within 2 weeks. Each department had to be surveyed in 1 day. Data collected, for all inpatients, included age and gender. For patients on systemic antimicrobial treatment, the antimicrobial/s, infection/prophylaxis site, reason in medical notes and guideline compliance were also collected. A central database using a web-based tool (WebPPS) developed in-house was used for data entry. Results: Combination of two or more antimicrobials accounted for 30% of use. Surgical prophylaxis was prolonged (>1 day) in 53% of cases. 'Intensive care' had higher proportions of treated patients (53% versus 29%), combination therapy (49% versus 31%), hospital-acquired infections (49% versus 31%) and parenteral administration (91% versus 61%). 'Reason in notes' was documented in 76%, and 'guideline compliance' occurred in 62% of patients. Conclusions: The ESAC PPS provided useful information on the quality of prescribing, which identified a number of targets for quality improvement. These could apply to specific departments or whole hospitals. Intensive care, which has different characteristics, should not be compared with general wards with respect to combination therapy, hospital-acquired infections or parenteral proportion. The study confirmed that the ESAC PPS methodology can be used on a large number of hospitals at regional, national, continental or global level.The ESAC project was supported by a grant from the European Centre for Disease Prevention and Control (ECDC; Grant Agreement 2007/001).peer-reviewe

An international investigation into student concerns regarding transition into higher education

The experience of transitioning into and starting higher education is a very individual one, with some applicants viewing the prospect of higher education as an unknown entity; for those who are first in their family or community to consider higher education, this can seem an "alien environment". These are just some of the issues that lead to applicants experiencing levels of concern when considering a transition into higher education. This international working group proposes to consider concerns across a wide range of participants: namely students who are in the process of transitioning into a higher education environment, and students who have recently completed this transition

Pre‑operative pain sensitivity : a prediction of post‑operative outcome in the obstetric population

Context: Experimental assessments can determine pain threshold and tolerance, which mirror sensitivity to pain. This, in turn, influences the post‑operative experience. Aims: The study intended to evaluate whether the pre‑operative pressure and electrical pain tests can predict pain and opioid requirement following cesarean delivery. Settings and Design: Research was conducted on females scheduled for cesarean section at a tertiary care hospital of the state. Twenty women were enrolled, after obtaining written informed consent. Materials and Methods: Pain assessment was performed on the eve of cesarean sections using three devices: PainMatcher® determined electrical pain threshold while the algometers PainTest™ FPN100 (manual) and PainTest™ FPX 25 (digital) evaluated pressure pain threshold and tolerance. Post‑operative pain relief included intravenous morphine administered by patient‑controlled analgesia, diclofenac (100 mg, every 12 h, rectally, enforced) and paracetamol (1000 mg, every 4‑6 h, orally, on patient request). Pain scores were reported on numerical rating scales at specified time intervals. Statistical Analysis Used: Correlational and regression statistics were computed using IBM SPSS Statistics 21 software (IBM Corporation, USA). Results: A significant correlation was observed between morphine requirement and: (1) electrical pain threshold (r = –0.45, P = 0.025), (2) pressure pain threshold (r = –0.41 P = 0.036) and (3) pressure pain tolerance (r = –0.44, P = 0.026) measured by the digital algometer. The parsimonious regression model for morphine requirement consisted of electrical pain threshold (r2 = 0.20, P = 0.049). The dose of morphine consumed within 48 h of surgery decreases by 0.9 mg for every unit increment in electrical pain threshold. Conclusions: The predictive power of pain sensitivity assessments, particularly electrical pain threshold, may portend post‑cesarean outcomes, including opioid requirements.peer-reviewe

Novice programmers and the problem description effect.

It is often debated whether a problem presented in a straightforward minimalist fashion is better, or worse, for learning than the same problem presented with a real-life or concrete context. The presentation, contextualization, or problem description has been well studied over several decades in disciplines such as mathematics education and psychology; however, little has been published in the field of computing education. In psychology it has been found that not only the presence of context, but the type of context can have dramatic results on problem success. In mathematics education it has been demonstrated that there are non-mathematical factors in problem presentation that can affect success in solving the problem and learning. The contextual background of a problem can also impact cognitive load, which should be considered when evaluating the effects of context. Further, it has been found that regarding cognitive load, computer science has unique characteristics compared to other disciplines, with the consequence that results from other disciplines may not apply to computer science, thus requiring investigation within computer science. This paper presents a multi-national, multi-institutional study of the effects of problem contextualization on novice programmer success in a typical CS1 exercise
