Molecular typing of multidrug-resistant Salmonella Blockley outbreak isolates from Greece.
During 1998, a marked increase (35 cases) in human gastroenteritis due to Salmonella Blockley, a serotype rarely isolated from humans in the Western Hemisphere, was noted in Greece. The two dominant multidrug-resistance phenotypes (23 of the 29 isolates studied) were associated with two distinct DNA fingerprints, obtained by pulsed-field gel electrophoresis of genomic DNA
The decision making process on public health measures related to passenger ships: the example of influenza pandemic 2009
Background. Public health measures at sea ports have posed a challenge for public health
competent authorities, especially in the context of the influenza pandemic of 2009. This paper
discusses the response of authorities to notifications of infectious diseases on passenger ships
and the importance of assessing the risks related to cases of influenza. It further provides options
for health measures and considerations for decision making during a pandemic such as
the influenza pandemic of 2009.
Discussion. Prevention and control of influenza have included action taken by both competent
port authorities and ships’ crews. Assessing the public health risk of each event reported from
ships to competent authorities at ports is important before advice is given on implementation of
control measures. Public health risk assessment involves appraisal of threats to passengers and
crew on board the ship as well as to the population in the community.
Summary. Any public health measures taken should be necessary and proportional to the threat.
Measures at ports cannot alone be effective in the prevention of the spread of a disease to the
community since other means of transport play a major role. Measures taken on board ships can
be effective in containing the disease. Consistent policy based on common protocols and carried
out by competent authorities at local, national, European, or international levels are essential.

Methodological aspects of a GIS-based environmental health inspection program used in the Athens 2004 Olympic and Para Olympic Games
BACKGROUND: The use of geographical information system (GIS) technologies in public health surveillance is gradually gaining momentum around the world and many applications have already been reported in the literature. In this study, GIS technology was used to help county departments of Public Health to implement environmental health surveillance for the Athens 2004 Olympic and Para Olympic Games. METHODS: In order to assess the workload in each Olympic county, 19 registry forms and 17 standardized inspection forms were developed to register and inspect environmental health items requiring inspection (Hotels, restaurants, swimming pools, water supply system etc), respectively. Furthermore, related databases were created using Epi Info 2002 and a geographical information system (GIS) were used to implement an integrated Environmental Health inspection program. The project was conducted in Athens by the Olympic Planning Unit (OPU) of the National School of Public Health, in close cooperation with the Ministry of Health and Social Solidarity and the corresponding departments of Public Health in all municipalities that were scheduled to host events during the Athens 2004 Olympic and Para Olympic games. RESULTS: A total of 44,741 premises of environmental health interest were geocoded into GIS databases and several electronic maps were developed. Using such maps in association with specific criteria, we first identified the maximum workload required to execute environmental health inspections in all premises within the eleven Olympic County Departments of Public Health. Six different scenarios were created for each county, based on devised algorithms in order to design the most effective and realistic inspection program using the available inspectors from each municipality. Furthermore, GIS applications were used to organize the daily inspection program for the Olympic games, provide coloured displays of the inspection results and link those results with the public health surveillance of specific cases or outbreak investigation. CONCLUSION: Our computerised program exhibited significant efficiency in facilitating the prudent use of public health resources in implementing environmental health inspections in densely populated urban areas as well as in rural counties. Furthermore, the application of simple algorithms in integrating human and other resources provided tailored and cost-effective applications to different public health agencies
Health promotion programs related to the Athens 2004 Olympic and Para Olympic games
BACKGROUND: The Olympic Games constitute a first-class opportunity to promote athleticism and health messages. Little is known, however on the impact of Olympic Games on the development of health-promotion programs for the general population. Our objective was to identify and describe the population-based health-promotion programs implemented in relation to the Athens 2004 Olympic and Para Olympic Games. METHODS: A cross-sectional survey of all stakeholders of the Games, including the Athens 2004 Organizing Committee, all ministries of the Greek government, the National School of Public Health, all municipalities hosting Olympic events and all official private sponsors of the Games, was conducted after the conclusion of the Games. RESULTS: A total of 44 agencies were surveyed, 40 responded (91%), and ten (10) health-promotion programs were identified. Two programs were implemented by the Athens 2004 Organizing Committee, 2 from the Greek ministries, 2 from the National School of Public Health, 1 from municipalities, and 3 from official private sponsors of the Games. The total cost of the programs was estimated at 943,000 Euros; a relatively small fraction (0.08%) of the overall cost of the Games. CONCLUSION: Greece has made a small, however, significant step forward, on health promotion, in the context of the Olympic Games. The International Olympic Committee and the future hosting countries, including China, are encouraged to elaborate on this idea and offer the world a promising future for public health
Prognostic factors related to sequelae in childhood bacterial meningitis: Data from a Greek meningitis registry
<p>Abstract</p> <p>Background</p> <p>Bacterial meningitis (BM) is a life-threatening disease, often related with serious complications and sequelae. Infants and children who survive bacterial meningitis often suffer neurological and other sequelae.</p> <p>Methods</p> <p>A total of 2,477 patients aged 1 month to 14 years old hospitalized in a Children's Hospital in Greece diagnosed with acute bacterial meningitis were collected through a Meningitis Registry, from 1974 to 2005. Clinical, laboratory and other parameters (sex, age, pathogen, duration of symptoms before and after admission) were evaluated through univariate and multivariate analysis with regard to sequelae. Analysis of acute complications were also studied but not included in the final model.</p> <p>Results</p> <p>The rate of acute complications (arthritis and/or subdural effusion) was estimated at 6.8% (152 out of 2,251 patients, 95%CI 5.8-7.9) while the rate of sequelae (severe hearing loss, ventriculitis, hydrocephalus or seizure disorder) among survivors was estimated at 3.3% (73 out of 2,207 patients, 95%CI 2.6-4.2). Risk factors on admission associated with sequelae included seizures, absence of hemorrhagic rash, low CSF glucose, high CSF protein and the etiology of meningitis. A combination of significant prognostic factors including presence of seizures, low CSF glucose, high CSF protein, positive blood culture and absence of petechiae on admission presented an absolute risk of sequelae of 41.7% (95%CI 15.2-72.3).</p> <p>Conclusions</p> <p>A combination of prognostic factors of sequelae in childhood BM may be of value in selecting patients for more intensive therapy and in identifying possible candidates for new treatment strategies.</p

Peer education in HIV prevention: an evaluation in schools
Background: In recent years a number of publications have come out about
the peer education method used as a tool in HIV prevention for young
people. Our survey aimed at testing the effectiveness of the peer
education method in HIV prevention in high school settings through a
pilot intervention. Methods: A peer education intervention took place in
10 high schools in Athens over a 1 year period. A cohort of 702 students
was surveyed (n 493 intervention group, n 209 control group) from 13
high schools through anonymous questionnaires based on the KABPs model,
pre- and post- intervention. The statistical package used was SPSS using
the chi(2)-test. Results: Compared with control students, the
intervention students were slightly empowered: (i) to increase their
personal responsibility; and (ii) to adopt a safer behaviour in sexual
practice. Knowledge did not show any significant modification between
the two groups. However, discrimination about certain groups of people,
the attitude about condoms and initiation of sexual relations did not
appear to be influenced. Conclusions: The peer education approach can
influence the behaviour of young people regarding their personal
protection from HIV infection. In order to test its effectiveness, peer
education should be further evaluated as a health education method in
HIV prevention in high schools, other youth settings and community
interventions, where the aim is behavioural change
