Immunisation against ringworm in cattle.

Immunisation against dermatomycoses in cattle was introduced in Gausdal, Norway, in 1979. A programme was implemented in which a six-year period of mandatory vaccination of all cattle was followed by vaccination on a voluntary basis. The prevalence of infected herds fell from 70 per cent in 1979 to 0 per cent in 1987. During the last five years, no newly infected herds have been registered in Gausdal. Proper disinfection of premises, the isolation of infected animals and other hygienic measures contributed to the successful result.

[Condoms and adolescents. A prospective study of a new method of teaching].

A prospective investigation was carried out with the object of assessing the effect of supplementary sex education for 1.3 hours in addition to the compulsory sex education in Danish elementary schools. One doctor did the teaching and practice with a condom was introduced as a new method of teaching. On an average, seven weeks before and seven weeks after this teaching session, these pupils completed a questionnaire. Altogether 451 pupils from the eighth and ninth classes participated. Great changes had occurred in the methods of contraception employed by the adolescents and in their attitudes to these from 1982 to date. Many more of the adolescents consider today that condoms provide the best form of contraception as compared with oral contraception. Nevertheless, only 9% of the adolescents were able to use a condom correctly. After the teaching session, knowledge about the correct use of a condom was significantly better and more had a positive attitude to condoms. A balance in information about methods of contraception is recommended and the young people should be sent to their own general practitioners for individual advice. On the basis of the results of this investigation, this teaching should be given already to pupils in the eighth classes.
