A survey in Torbay, England, indicated substantial sexual interaction of an unsafe kind between young residents and tourists. A pilot programme is described which sought to promote safer sexual behaviour: the attention of both tourists and local people who frequented nightclubs was engaged by peer groups who conveyed educational messages.
At a global level there are considerable differences between regions in the levels of prevalence, and rate of transmission, of the Human Immunodeficiency Virus (HIV)/Acquired Immune Deficiency Syndrome (AIDS). Furthermore there are differences between regions in the social and demographic characteristics of HIV carriers/AIDS sufferers (e.g. heterosexuals, homosexuals, injecting drug users, infants). It is notable that Asia has generally lagged behind other regions in the spread of HIV. However recently Thailand has acknowledged rapidly increasing levels of infection. This paper is structured in terms of three broad sections. (1) An outline of some basic epidemiological principles concerning the transmission of HIV which help account for the regional variations in prevalence; (2) a description of the emerging awareness of HIV as a public health problem within Thailand; (3) a review of the social characteristics of HIV carriers in Thailand, interpreted by reference to the wider social context, chiefly in terms of; the commercial sex industry/sexual lifestyles, international tourism, and injecting drug dependency. Reference is also made to impressions of the personal response of individuals learning of their HIV seropositive status. A brief comment compares the sexual culture and sex industry in Thailand to that of other South East Asian countries (most notably the Philippines). The paper highlights the importance of considering the particular social and historical factors which shape and sustain the transmission of HIV within a particular country.

A survey of 16-21 year old people in Somerset was undertaken to find out about their sexual behaviour prior to mounting a local education campaign on AIDS. A representative sample of 400 people, using quota sampling in 40 randomly selected electoral wards, completed a schedule structured part self administered questionnaire. Of these, 371 (92%) considered themselves heterosexual. Nearly half (47%) of the 16 year olds had engaged in sexual intercourse, rising to 89% by the age of 21. Mean frequency of sexual intercourse among the sexually active is 62 per year. The frequency of partner change decreases with increasing age for non-virgins from 2.1 for 16 year olds to 1.5 partner changes per year for 21 year olds (mean frequency 1.7 per year, ie, a new partner every 7 months). This level of sexual activity could eventually give rise to HIV prevalence rates similar to those found in Africa, i.e., 15-100 HIV antibody positive per 1000.
Peritoneal oocyte and sperm transfer (POST) was performed under ultrasound guidance and local anesthesia by the transabdominovesical route for a patient with unexplained infertility. This resulted in an intrauterine pregnancy confirmed by a raised beta-human chorionic gonadotropin (hCG) level and an ultrasound scan.
