This chapter presents different means by which community initiatives have been undertaken to reduce the prevalence and incidence of genital and allied infections caused by Chlamydia trachomatis. As most of these infections in the majority of infected individuals do not produce symptoms that are likely to urge them to attend any health care unit, screening programmes are mandatory to be able to influence the epidemic of infections with this agent. In many societies there has been a skewed gender distribution in the number of chlamydia-positive persons; this probably indicates that diagnostic service activities have been directed more against one gender than the other. The important role of partner notification, as in the case of other sexually transmitted infections, has been documented. Different means of community initiative have included counselling of school children and groups of persons more likely to be infected. Counselling by the pharmacy has an important role in many societies. Selected cohorts have been offered - via the mass media, Internet, radio and television programmes - sampling kits which can be mailed to a laboratory for testing. The establishment of youth clinics has been found effective for detecting teenagers harbouring C. trachomatis, similarly to screening at antenatal clinics. The offer of free consultations, aetiological tests and therapy has been a part of community initiatives, mimicking the services offered for some of the classic sexually transmitted infections. This chapter considers the usefulness of different test methods and stresses the need to retest those found to be positive. Barriers to the successful introduction of screening activities and diagnostic services are also considered. 相似文献

Population-based studies on contact allergy with retesting of individuals are infrequently performed. Variable degrees of persistence are reported when individuals with contact allergy are retested with years in between. The patch test results of 270 individuals tested in 2005-2006 are presented and the pattern and frequency of sensitization discussed. Persistence when compared with patch test results from 1997-1998 is reported. 270 twin individuals with and without hand eczema underwent patch testing with the TRUE Test((R)) (Mekos Laboratories AS, Hilleroed, Denmark) in 1997-1998 and again in 2005-2006 as part of a larger study. In 2005-2006, a total of 74 (27.4%) of the 270 individuals had at least 1 positive patch test and 20 (7.4%) of the 270 had 2. The frequency in men and women was 9/90 (10%) and 65/180 (36.1%), respectively. The frequency of contact allergy in individuals with and without hand eczema was 59/185 (31.3%) and 15/85 (17.6%), respectively. The most prevalent contact allergies were to nickel, thiomersal, and fragrance mix I. All together, 74% of the positive reactions were reproduced. The frequency of contact allergy in this population-based cohort with hand eczema was comparable with previous reports. Persistence of contact allergy after many years was confirmed. 相似文献

OBJECTIVE: To examine the meaning that people with genital chlamydial infection attribute to retesting as part of their treatment management. METHODS: Unstructured interviews with 50 heterosexual patients (40 female and 10 male) who had or had had genital chlamydia infection. Recruitment was via a genitourinary medicine clinic and a contraceptive clinic. RESULTS: The return visit was understood in terms of the retest. The retest occupied a pivotal position in the infection experience and was invested with symbolic significance because it provided a means by which to deal with feelings of bodily pollution. It marked the end of dirtiness that was important for the restoration of identity. It also marked the beginning of cleanness that was important in relation to sexual relationships. CONCLUSION: The sociocultural construction of sexually transmitted infections shapes the individual experience of having chlamydial infection. This perspective sheds light on the meaning that individuals invest in aspects of infection management. It is important for some people to know rather than assume that their infection has been eliminated, a function that is fulfilled by the retest. When retesting is not available, individuals may use increasingly available opportunistic chlamydia testing for this purpose with consequent cost and resource implications. 相似文献

IntroductionHIV retesting during late pregnancy and breastfeeding can help detect new maternal infections and prevent mother‐to‐child HIV transmission (MTCT), but the optimal timing and cost‐effectiveness of maternal retesting remain uncertain.MethodsWe constructed deterministic models to assess the health and economic impact of maternal HIV retesting on a hypothetical population of pregnant women, following initial testing in pregnancy, on MTCT in four countries: South Africa and Kenya (high/intermediate HIV prevalence), and Colombia and Ukraine (low HIV prevalence). We evaluated six scenarios with varying retesting frequencies from late in antenatal care (ANC) through nine months postpartum. We compared strategies using incremental cost‐effectiveness ratios (ICERs) over a 20‐year time horizon using country‐specific thresholds.ResultsWe found maternal retesting once in late ANC with catch‐up testing through six weeks postpartum was cost‐effective in Kenya (ICER = $166 per DALY averted) and South Africa (ICER=$289 per DALY averted). This strategy prevented 19% (Kenya) and 12% (South Africa) of infant HIV infections. Adding one or two additional retests postpartum provided smaller benefits (1 to 2 percentage point increase in infections averted versus one retest). Adding three retests during the postpartum period averted additional infections (1 to 3 percentage point increase in infections averted versus one retest) but ICERs ($7639 and in Kenya and $11 985 in South Africa) greatly exceeded the cost‐effectiveness thresholds. In Colombia and Ukraine, all retesting strategies exceeded the cost‐effectiveness threshold and prevented few infant infections (up to 31 and 5 infections, respectively).ConclusionsIn high HIV burden settings with MTCT rates similar to those seen in Kenya and South Africa, HIV retesting once in late ANC, with subsequent intervention, is the most cost‐effective strategy for preventing infant HIV infections. In these settings, two HIV retests postpartum marginally reduced MTCT and were less costly than adding three retests. Retesting in low‐burden settings with MTCT rates similar to Colombia and Ukraine was not cost‐effective at any time point due to very low HIV prevalence and limited breastfeeding. 相似文献
