The clinical characteristics of seven healthy subjects who required hospital care for an exhaustion syndrome due to extenuated physical exercise during participation in a public marathon are presented. All the patients were used to practising sports activities and in all the cases the symptoms of exhaustion appeared in the last few kilometers of the race. The most frequent symptom found in all the patients was lipothymia with falling to the ground followed by gastrointestinal manifestations, muscle cramping and fever. Upon analysis the signs of rhabdomyolysis and others suggestive of dehydration were observed in all the cases. Leukocytosis was observed in four and hypopotassemia in two. Evolution was good in all the cases with rest and hydroelectrolytic reposition. Finally, the preventive measures to avoid heat stroke and exhaustion syndromes in public marathons are reported.
The range of complementary therapies available has increased. The treatments offered may improve the 'whole' person but not the 'part' which is diseased. Inquiry into the length and type of training of therapists is needed to ensure ethical practice. Recognition of the usefulness of some complementary therapies by orthodox medical practitioners is slowly increasing. Caution should continue to be exercised.

Baby walkers are a potential cause of accidents in infants from 6 months to 1 year of age. We conducted a study to determine the patterns of walker use, the different points of view of the parents and the baby walker-related injuries in our health district. For this purpose, between November 1, 1992 and January 31, 1993, a questionnaire was given to 207 parents of infants between the ages of 3 and 24 months in order to evaluate the socioeconomic situation and to determine the patterns of walker use. We found that 42% of the infants between 4.3 and 13.4 months of age had a baby walker and 46.7% of them used it daily. There was a significant inverse relationship between the walker usage and the maternal level of education. Of the infants who used walkers, 24.9% had experienced an accident (falls 76.2%, injuries 14.3% and hospital admission 4.8%). The accidents were significantly more common in boys. The advantages reported by parents (for using walkers) were: 46.3% none, 34.2% comfort, 10.9% infant amusement, 12.9% help to walk earlier. Dangers reported by the parents included: 27.2% none, 33.5% leg deformities, 43% accidents (33.5% injuries and 12% falling down stairs). In conclusion, our results show a slightly lower number of walker users and walker related accidents when compared to other reports. Parents have mistaken notions about the use of baby walkers. Hence, the need for continued health education campaigns related to this subject remain.
This is a qualitative analysis of the non-structured responses to a survey (see 'Notes') which elicited people's attitudes towards being treated by HIV-positive dentists. These findings are discussed in terms of a sociology of knowledge, that is, an understanding of how individuals come to believe what they do. It uses the concept of 'public' and 'private' accounts to explore some of the themes which emerged.
The frequency of contact allergy to the 10 best-selling women's perfumes was studied in 335 consecutive female eczema patients by patch testing. The diagnostic ability of the fragrance mix, in relation to these products, was evaluated. Of eczema patients, 6.9% had a positive patch test to one or more of the perfumes, and 56.5% of these had a concurrent positive reaction to the fragrance mix. Hence, testing with the patients' own cosmetics is a significant part of diagnosing perfume allergy. The clinical relevance of the patch-test reactions to the commercial perfumes was equal to that of the fragrance mix, as judged from the patient's history and use testing with one of the perfumes. At least three of the chemically defined sensitizers in the fragrance mix were detected in all the perfumes by gas chromatography-mass spectrometry, which indicates that the fragrance mix is a good imitation of actual exposure.

This article is intended to provide a comprehensive overview regarding motives, implications, aims, history, underlying principles, and methods as well as criticism and potential impact of "Evidence Based Medicine" (EBM). The term was defined and the movement initiated by British and Canadian clinicians-epidemiologists. So far, a translation and national adaptation remain to be established. It seems that EBM is suited to compensate for many irrationalities within our clinical practice and health care system. Not only should the underlying principles, aims, methods, and techniques of EBM be considered in clinical practice and primary care in Germany. They should also be emphasized during medical training and postgraduate education and in the needs-oriented distribution of scarcening resources.
