[Cancerology training in France].

During the last years, training in cancerology in France has been developed extensively. The importance of training as a major element in the fight against cancer is now widely recognized. Cancerology teaching has been improved in the curse of clinical science for medical students as well as the training of general practitioners. Special courses qualifying for the Diploma of Specialised Complementary Studies in Oncology are available to Cancerologists. While appreciating the positive aspects of cancerology training at these different levels, we must stress a certain number of weak points that need to be corrected. Several propositions tending to further improve cancerology training are proposed. The implementation of these recommendations should allow France to maintain its rightful place in cancerology within the European Community.

A reference preparation of creatine kinase BB isoenzyme.

Creatine kinase (CK; EC 2.7.3.2) catalytic activity in serum is widely measured in clinical chemistry practice and provides information for diagnosis and follow-up in many pathological conditions affecting heart, muscle, and brain. Depending on the organ involved, the predominant CK isoenzyme in serum varies. However, routine methods measure total CK catalytic activity, and standardized methods for doing so have been recommended by the International Federation of Clinical Chemistry and by several national scientific societies. Many commercial kits for those methods are now available. With use of a reference material for CK, commercial reagents can be compared with standardized methods, improving confidence in the results. Here we present a reference preparation of CK consisting of the BB isoenzyme purified from human placentae. We describe the procedure of purification and the properties of the lyophilized preparation of CK-BB, which has been certified by the Community Bureau of Reference of the Commission of the European Communities under the designation CRM 299. The preparation can be used to calibrate assays of the catalytic activity of CK-MM and CK-MB, as well as CK-BB.

Community networking as a means for identifying people with diabetes in a rural, predominantly bicultural community in New Zealand.

AIMS: To assess the use of community networking to estimate the prevalence of diabetes in a predominantly New Zealand Maori and European community. METHODS: A cross-sectional survey of people with known diabetes identified either through general practice or community networks (others with diabetes, public notices or public meetings) was undertaken. Ascertainment was compared using capture-recapture methods for two independent samples. RESULTS: Overall ascertainment by community networking was greater for Maori than Europeans (40 +/- 3% vs 15 +/- 2%, p < 0.001). Ascertainment using general practice registers was comparable in the two ethnic groups (48 +/- 4% vs 55 +/- 5%, respectively). Women were more likely than men to be contacted through community networking (odds ratio 1.47, 1.05-2.06). CONCLUSION: In closely knit communities, community networking provides an independent source for estimating the prevalence of diabetes.

Assessment of exposure to lead of the general population in the French community through biological monitoring.

The aim of the council directive of 29 March 1977 of the European Community (1) is the screening for non-work-related lead exposure levels in the general populations of European (member) countries. In France, such testing was carried out in eight metropolitan areas (having more than 500,000 inhabitants), another eight "critical" areas surrounding industrial emission sources and one area (Vosges) having a high level of lead contamination in the water. In view of the reference values (maximum 35 micrograms/dl in an individual blood sample) adopted by the directive, the situation is most serious in the area where the exposure is due to the lead contamination in the water. Individuals here run a seven times greater risk of exceeding the 35 micrograms/dl blood-lead limit relative to urban populations where the lead comes mostly from vehicle emissions into the atmosphere (i.e. 9.3% of the blood-lead values of the Vosgian sample exceed 35 micrograms/dl; 3.5% for the industrial complexes which deal with lead and 1.4% for the urban zone). While these vehicle exhausts are the subject of much current concern, in perspective, the problem of lead pipe contaminated drinking water appears to be of far greater importance.

Effect of ultrasound agitation on the release of heavy elements in Certified Reference Material of human hair (CRM BCR 397).

An ultrasonic-assisted leaching procedure was developed for the determination of heavy elements (As, Cu, Cd, Pb, and Zn) in Certified Reference Material of human hair (CRM 397) provided from the Community Bureau of Reference (BCR) of the Commission of the European Community. Concentrated nitric acid-30% hydrogen peroxide (2 + 1) was used for the leaching method. The effects of different factors on acid leaching of elements, such as presonication time (without ultrasonic stirring), sonication or exposure time to ultrasound, and temperature of the ultrasonic bath have been investigated. Optimum values of these parameters were selected for the maximum extraction of heavy metals from CRM BCR 397 and human scalp hair samples of normal healthy males. To check the validity of the proposed method, a wet acid digestion method was used to obtain the total elemental concentration in CRM BCR 397 and scalp hair samples. Cu and Zn in leachate and digests were measured by flame atomic absorption spectrometry using a conventional air/acetylene flame, while As, Cd, and Pd were determined by electrothermal atomic absorption spectrometry. Under optimized conditions, the recovery for Zn, Cd, Pd, As, and Cu was 98, 98.5, 97.5, 98.2, and 95%, respectively, of those obtained with the wet acid digestion method.

The health hazards of unemployment and poor education: the socioeconomic determinants of health duration in the European Union.

The effect of socioeconomic status on the likelihood that an individual enters a period of poor health is examined using an Accelerated Failure Time methodology. This study employs data from the European Community Household Panel for the years 1994-2002 across 13 European countries, using the Physical and Mental Health Problems, Illnesses and Disabilities measure of physical health. Some socioeconomic status indicators do impact on the length of time an individual remains in good health - these being unemployment, which has a negative effect, and education, which has a positive effect - but others, such as income, have far less of an impact. Age and gender effects are also found.

Skin diseases in Ghana and the UK.

BACKGROUND: Although diseases of the skin have been studied in some African countries, the provision of dermatology services is as yet a relatively underdeveloped aspect of medicine in sub-Saharan Africa. OBJECTIVE: To determine the pattern of skin diseases seen in a sub-Saharan community and to compare it with that seen in a European community. METHODS: The diagnoses of the principal presenting complaint of 2254 consecutive new patients seen at the dermatology clinic of Komfo Anokye Teaching Hospital (KATH), Kumasi, Ghana, are presented and compared with those of 3383 consecutive new patients seen at the dermatology clinic of The William Harvey Hospital (WHH), Ashford, Kent, UK. RESULTS: The most common conditions in Ghana were infections (46.3%; UK, 12%). In the UK, the most common conditions were malignant and premalignant diseases of the skin (22.2%; Ghana, 0.5%) and benign tumors (16.8%; Ghana, 0.5%). Dermatitis was common in both countries (Ghana, 18.4%; UK, 16.0%). Psoriasis was more common in the UK (6.2%) than in Ghana (0.4%). In Ghana, fixed drug eruption, mainly due to cotrimoxazole (Septrin), was not rare (27 cases), and complications from cosmetic skin lightening creams were a frequent problem among women (86 cases). No cases of rosacea were found in Ghana, but it was not uncommon in the UK (1.6%). CONCLUSIONS: The patterns of skin diseases are different in the two countries. It is hoped that this study may help to catalyze the further development of dermatology services in Ghana.

[Ergonomics in the context of mining].

After a short historical account of ergonomics, the speaker exposes its objectives: amelioration of working conditions, elimination of tasks that are beyond the worker's abilities, search for working norms and conditions according to men's needs and aspirations. He then enlarges on the ergonomical methods: measure and quantification of tasks, reckoning of the working situation in its whole, multi-disciplinary approach and thus necessity to set up teams, participation of the workers concerned. He stresses that the iron and steel industry and the mining industry have taken a leading part in ergonomics and that this part has been amplified by the support of the departments of the European Communities.

Indoor dose in Milano (Italy).

This work is related to the problem of providing a more careful evaluation of the population exposure to natural radiation background, and was carried out in connection with the ENEA programmes on the assessment of indoor exposure doses in Italy. A large number of works in recent years have pointed out the main contribution of the indoor dose to the natural dose received by the members of the general population, and the large contribution of radon daughter inhalation. Different building materials and techniques lead to different exposure doses. In Milano such materials can be quite different in kind (bricks, concrete, gypsum by-products, tile-stone, paving-tile, etc.) and origin (national and foreign). For this reason, a collection of indoor doses in Milano is not only complementary to analogous investigations carried out in other Countries of the European Communities, but the obtained information can be compared with other large European towns. As agreed, a large number of various dwellings in Milano were investigated to evaluate the external gamma-ray exposure rate, and measurements of indoor radon concentrations were performed for some of them. Various typical building materials used in Lombardia were also analysed by means of gamma-ray spectrometry.

The production of pig tissue sulphadimidine reference material.

The production of stable homogeneous reference materials containing the antimicrobial agent sulphadimidine in pig tissue is described. These were commissioned by the Community Bureau of Reference (BCR), established by the Commission of the European Communities, to promote improvements in analytical accuracy and to ensure uniformity of results determined by member states. Sulphadimidine-containing tissue powders (400 vials each of muscle, liver and kidney) were prepared by orally dosing pigs with drug, producing lyophilized tissue powders and blending these with negative tissues from unmedicated animals to achieve target concentrations. Details of the production process, the stabilizing procedure developed and the analytical assessments of homogeneity and stability are given.

Nutrition and health of elderly people in Europe: the EURONUT-SENECA Study.

In 1988 EURONUT, the umbrella European Community (EC) Concerted Action on Nutrition and Health, initiated a major European multicenter study, named SENECA,* to study cross-cultural differences in nutritional issues and life-style factors affecting health and performance of elderly people in Europe. According to a strictly standardized methodology, 2,586 elderly subjects--born between 1913 and 1918--have been studied in 19 towns across Europe, using a mixed longitudinal design. Data regarding nutrient and food intakes, diet habits, diet awareness, nutritional status, health, and life-style factors were collected and are partially presented in this paper. There was considerable variability from site to site--even within countries--in dietary intake, in both quantity and composition; blood biochemistries; life-style factors; health; and performance. Implications of the observed wide variability will be studied longitudinally.

[Safety monitoring of disposable medical products].

In 1988 medical devices have become a part of the German AMG. According to this law safety monitoring similar to the one with drugs should be introduced. In the United States the so called medical device report regulation is responsible for safety monitoring. They have demonstrated that the risks of these instrument cannot be neglected. Therefore medical organisations or technical supervising institutions in Germany should take care of safety monitoring with medical devices, because otherwise supranational organisations, which are already present in different countries, or European community authorities will become responsible after the introduction of the free European market in 1992.

[European surveillance of infectious diseases: the case of AIDS and tuberculosis].

In 1992, the Maastricht treaty gave specific responsibilities to the European Community in the field of research, information and health education. Several European surveillance systems for infectious diseases have been organised. The surveillance of AIDS was set up in 1984 after the emergence of this new disease. Seven western European countries participated initially. The system currently covers 48 of the 51 countries of the WHO European region. Based on a common case definition, it enables analysis of trends and comparisons which considerably facilitate the understanding of the epidemic and its determinants, and the evaluation of preventive actions. European countries have now decided to set up a reporting system for HIV infection. The surveillance of tuberculosis started in 1996 in response to the reversal of trends in reported cases observed in western Europe and to the threat of multi-drug resistant tuberculosis epidemics. Common recommendations on definitions and data collection procedures facilitated its establishment. Most countries of the WHO European region participated in the first year, revealing a very heterogeneous epidemiological situation. The next objective is to set up a surveillance system for antituberculosis drug resistance. The European surveillance of AIDS and tuberculosis are examples of systems adapted to the specific characteristics of Europe: similarities in diagnostic procedures, similarities in access to treatments, and common requirements regarding both the exchange of information and the coordinated response to public health threats. They are not simply looking for a common denominator. They are creating a real momentum among participating countries towards a better quality and a higher level of pertinence of the information.

[Community requirements relating to drugs derived from human blood and plasma].

Since the adoption of the first pharmaceutical directive in 1965, the pharmaceutical legislation of the European Community has constantly pursued two objectives: the protection of public health and the free movement of products. Directive 89/381/EEC covers stable industrially prepared blood derivatives, intended for a large number of patients, namely albumin, coagulation factors and immunoglobulins. Whole blood, plasma and cellular components are excluded from the scope of the directive. As a consequence of the inclusion of blood derivatives in Community pharmaceutical legislation, these products are now subject to its general provisions regarding manufacturing and marketing authorization. The principles of good manufacturing practice laid down in Directive 91/356/EEC and detailed in a guide for manufacturers have become mandatory, as well as the tests in Directive 91/507/EEC aimed at demonstrating quality, safety and efficacy for the purpose of marketing authorization. The European format for the application file as well as the Community procedures for marketing authorization are applicable. In addition to these general provisions, which are applicable to all medicinal products, Directive 89/381/EEC contains several elements which are specific to medicinal products derived from human blood or plasma. The measures for selection and control of blood donors recommended by the Council of Europe and the World Health Organization have become compulsory. Moreover, for these particularly sensitive products, the Council has explicitly demanded the application of validated manufacturing and purification processes, in order to guarantee, insofar as the state of technology permits, the absence of specific viral contamination. For new medicinal products, the Directive entered into force on 1 January 1992. For products already on the market, a transitional period of one year was provided, during which the Member States had to proceed with the review of these products. The objective of Community self-sufficiency in blood and blood derivatives by voluntary unpaid donations is clearly expressed in the text of the Directive and the Member States have to inform the Commission on measures taken in this area. Thus, in adopting the Directive, the 12 Member States established as an objective that self-sufficiency be attained through voluntary unpaid blood donation. But, in addition to the Directive, the general rules of the EC Treaty are applicable, namely with regard to free movement of products, public procurement and monopolies.

[Elaboration of a course in training galleries for use in testing of self rescue devices].

The approval of self rescuer devices for use in the underground needs, among other things, human testing in training galleries. As the training galleries are not the same in the different central rescue stations, the C.C.R. was entrusted with the task of developing a standard test for Belgium. After comparing data with two other countries of the E.E.C. and having devised two experimental courses, the C.C.R. launched a project for "Community Ergonomics Action" with the financial support of the Commission of the European Communities. This financial support enabled the C.C.R. to purchase equipment for the continuous measurement of various physiological parameters. This equipment was used to determine as accurately as possible the effort involved in passing through a specific type of roadway at a given speed. The resulting information helped device a third test course which entails an average oxygen uptake of approximately 1,2 l/min; the paper gives a detailed description of this test.

Latent class versus two-part models in the demand for physician services across the European Union.

Using three waves of data from the European Community Household Panel, this paper estimates demand for physician services equations for 12 European countries. We focus on the selection of the most appropriate econometric specification for visits to general practitioners and to specialists among two-part and latent class models. The distinction between the demand of services from these two types of physicians allows us to distinguish cases in which two-part perform better than latent class models, evidence which is different from previous findings in the literature. The results suggest that latent class models are more appropriate than two-part models to estimate general practitioners utilisation while the opposite is found for visits to the specialists.
