Target registration and target positioning errors in computer-assisted neurosurgery: proposal for a standardized reporting of error assessment

THE INTERNATIONAL JOURNAL OF MEDICAL ROBOTICS AND COMPUTER ASSISTED SURGERY, Issue 4 2009
Gerlig Widmann
Abstract Background Assessment of errors is essential in development, testing and clinical application of computer-assisted neurosurgery. Our aim was to provide a comprehensive overview of the different methods to assess target registration error (TRE) and target positioning error (TPE) and to develop a proposal for a standardized reporting of error assessment. Methods A PubMed research on phantom, cadaver or clinical studies on TRE and TPE has been perfomed. Reporting standards have been defined according to (a) study design and evaluation methods and (b) specifications of the navigation technology. Results The proposed standardized reporting includes (a) study design (controlled, non-controlled), study type (non-anthropomorphic phantom, anthropomorphic phantom, cadaver, patient), target design, error type and subtypes, space of TPE measurement, statistics, and (b) image modality, scan parameters, tracking technology, registration procedure and targeting technique. Conclusions Adoption of the proposed standardized reporting may help in the understanding and comparability of different accuracy reports. Copyright © 2009 John Wiley & Sons, Ltd. [source]

Economic Analysis Of The Droit De Suite, The Artist's Resale Royalty

AUSTRALIAN ECONOMIC PAPERS, Issue 4 2003
J. D. Stanford
Interest in the Droit de Suite, the artist's resale royalty, has been re-kindled by the decision of the European Union to introduce such a scheme to apply from 2006. The general nature of the Droit de Suite as an extension of copyright is discussed. The specific proposals for a Droit de Suite in Australia are analysed. Economic arguments support the sceptical view of the Droit de Suite. It is argued that the introduction of the Droit de Suite would be predicted to reduce sales of new paintings, that selling activity would move to jurisdictions which do not have a Droit de Suite and that artists would prefer to alienate their Droit de Suite by sale of a painting. The economic analysis is supplemented by an empirical study of art auction prices of 72 artists in Australia over the period 1973,1989 which reveals that the works few artists achieve a capital gain on sale in the secondary market re-inforcing the view that, if implemented, a Droit de Suite would provide payments to only a small number of artists who are likely to be in good economic circumstances. The burden of the Droit de Suite is shown to fall on the collector when selling paintings. The effect of the imposition of the Droit de Suite will be to lower the gain to collectors of paintings. It is concluded that the Australian proposal for the Droit de Suite is based on an inadequate analysis of the art market and would require a registration procedure for art works incurring heavy costs in relation to the funds available for distribution.

Surveillance and measuring trends of stroke in Japan: The Takashima Stroke Registry (1988 , present)

INTERNATIONAL JOURNAL OF STROKE, Issue 2 2007
Yoshikuni Kita
This stroke registry is a population-based, prospective, observational study whose objective is to monitor trends in the incidence and case-fatality of stroke in Japan. Takashima County is located in the rural area of the Shiga prefecture in central Japan, having a stable population of approximately 54,000. It is a farming community with similar cultural values and standards of living throughout the region. The population has remained fairly stable during the 16-year study period. 1750 stroke cases (men 937 and women 813) were registered during 1988,2002. The average ages of the men and women patients were 69.4 and 74.4 years respectively. Stroke diagnostic criteria are established for the Monitoring System for Cardiovascular Disease commissioned by the Ministry of Health and Welfare, Japan. These criteria were based on WHO-MONICA project. Takashima registry system was planned to capture all the cases in the study area by covering all the hospitals of the county. To ensure that eligible patients hospitalized outside the county were not omitted, registration procedures were also conducted at three high-level medical facilities within the Shiga region but outside the county. Due to the high rate of computed tomography use in Japan the identification of stroke cases within the study area is almost complete and stroke diagnosis and classification are accurately recorded.

An appraisal of methods for measurement of pesticide transformation in the groundwater zone,

PEST MANAGEMENT SCIENCE (FORMERLY: PESTICIDE SCIENCE), Issue 4 2001
Minze Leistra
Abstract Laboratory and field studies show that pesticides may be transformed in the groundwater zone. Possible reaction mechanisms are chemical hydrolysis, catalytic reduction and aerobic or anaerobic microbial transformation. Transformation in the groundwater zone can be an important element in the advanced evaluation of the potential risk arising from a pesticide in the public drinking water supply. However, rate and pathway of transformation can show large differences, depending on the bio-geochemical conditions in the groundwater zone. Knowledge of the reaction mechanisms and the effect of aquifer conditions would allow vulnerable and low-vulnerable application areas for a pesticide to be delimited. An outline is given of possible approaches to quantifying these transformation processes and using the results in registration procedures, especially in the EU and its member states. Furthermore, areas where there is need for continued research and better understanding are highlighted. © 2001 Society of Chemical Industry [source]

Impact of registration procedures on antibiotic policies

CLINICAL MICROBIOLOGY AND INFECTION, Issue 2001
B. Schlemmer
There is increasing concern over antibiotic resistance and its spread in common bacterial species, such as Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae and Escherichia coli. This results in increased morbidity and mortality. Over consumption of antibiotics has been reported in many settings and underlines the need for improving antibiotic policies. Crude measures of both antibiotic use and antibiotic resistance do not share a strong cause-and-effect relationship. However, this relationship is highly suggestive at a country level, at a hospital level, at a cohort level and at an individual level. In addition to overuse, antibiotic misuse has also to be considered, because of its impact on promoting antibiotic resistance, related to choice, dosage, dosing regimen or duration of therapy [1].
