A case of vertebrobasilar stroke during oxygen-ozone therapy
No full textnon availableDespite only sporadic observations, the use of medical oxygen-ozone therapy is a largely diffused treatment for lumbar disk herniation that has failed to respond to conservative management. Combined intradiscal and periganglionic injection of medical ozone and periganglionic injection of steroids are presumed to have a cumulative effect enhancing the overall outcome of treatment for pain caused by disk herniation. To our knowledge, this is the first reported case of stroke during such medical application. The patient had Anton's syndrome as a result of top of the basilar hypoperfusion. © 2004 by National Stroke Association
A principle-based approach to AI: the case for European Union and Italy
Full text linkAs Artificial Intelligence (AI) becomes more and more pervasive in our everyday life, new questions arise about its ethical and social impacts. Such issues concern all stakeholders involved in or committed to the design, implementation, deployment, and use of the technology. The present document addresses these preoccupations by introducing and discussing a set of practical obligations and recommendations for the development of applications and systems based on AI techniques. With this work we hope to contribute to spreading awareness on the many social challenges posed by AI and encouraging the establishment of good practices throughout the relevant social areas. As points of novelty, the paper elaborates on an integrated view that combines both human rights and ethical concepts to reap the benefits of the two approaches. Moreover, it proposes innovative recommendations, such as those on redress and governance, which add further insight to the debate. Finally, it incorporates a specific focus on the Italian Constitution, thus offering an example of how core legislations of Member States might contribute to further specify and enrich the EU normative framework on AI
An ethical perspective on Artificial Intelligence: Principles, rights and recommendations
No full textClimate and stroke: a controversial association
No full textThe study recently published by Wang et al. (2009), which
is based on one of the largest population-based surveys,
shows a trend in the occurrence of intracerebral hemorrhages
(ICH) with temperature variations in Brisbane. His
work showed a statistically significant increase (15%) of
ICH for every 1°C increase in daily T° max.
In the literature, the topic is considered controversial,
and the study raised many observations that we would like
to discuss in this paper.
Our group in collaboration with the Department of
Neurology at Sohag University (Fawi et al. 2009) in southern
Egypt, under the patronage of the Egyptian Ministry for
Higher Education, reported a similar trend of higher
prevalence of hemorrhagic events in patients admitted to
the local hospital during a 2-year survey. In southern Egypt,
we observed a peculiar spring–summer trend: our researches
demonstrated an astonishing increase in hemorrhagic events.
Stroke unit admissions for hemorrhagic stroke reached the
surprising prevalence of 47.7% while the local spring–
summer temperature range was an average of 33°C (Tmax
40°C, Tmin 26°C). The hemorrhagic events in the autumn–
winter time frame reached 31%. A meta-analytic approach to the topic may be recommended
in order to better focus the relationships between
disease outbreaks and meteorological data on a global scale.
Statistical testing for the meta-analysis should be performed
with traditional methodology for homogeneity and significance;
χ2 techniques (for goodness of fit to the null model
of equal distribution of strokes in each climatic area) may
be recommended, along with 95% confidence intervals, to
evaluate the seasonal pattern of stroke hospitalization. Two
strategies may be used to estimate the relative risk of stroke
occurring at specific seasons. One strategy assumed that all
strokes would be evenly distributed in onset among the
12 months, and therefore compared the observed proportion
relative to the proportion expected, based on the total
number reported. The second strategy is based on a
comparison of the observed number of strokes compared
with the average for the other months of the year,
normalized for the month under consideration. In this
particular analysis, the expected number of events that
were reported to have occurred, for instance, between
January and March, should be compared with the number
of events occurring in the remaining 9 months of the year
(divided by 3, to normalize for the number of months in the
time period under consideration), and the relative risk was
the number of strokes actually reported, divided by the
number expected

An ethical perspective on Artificial Intelligence: Principles, rights and recommendations/Una prospettiva etica sull’intelligenza artificiale: princìpi, diritti e raccomandazioni
No full textAs technologies become more and more pervasive in our everyday life new questions arise, for example, about security, accountability, fairness and ethics. These concerns are about all the realities that are involved or committed in designing, implementing, deploying and using the technology. This document addresses such concerns by presenting a set of practical obligations and recommendations for the development of applications and systems based on Artificial Intelligence (AI) techniques. These are derived from a definition of rights resulting from principles and ethical values rooted in the foundational charters of our social organization
