The rise and fall of sexually transmitted diseases in Sweden.

Syphilis appeared in Sweden in 1497. It was recognized as a sexually transmitted disease that rapidly spread in the upper classes and later to the poor. It ravaged the country in the eighteenth and nineteenth centuries. At that time the concept of venereal disease included all sexually transmitted diseases. Preventive measures were introduced. They were based on information, medical intervention and elimination of risk factors. Registration of hospitalised patients was introduced in the eighteenth century. The highest incidence of syphilis occurred during the First World War. In the last decade the incidence of sexually transmitted disorders has abruptly decreased. Thus the yearly incidence of gonorrhoea has decreased from 40,000 to 500 cases. The law demands contact tracing with obligatory testing. People who deliberately expose others to risk may be condemned to isolation for an unrestricted time. This legislation has probably contributed less to the successful containment than the fact that information on aids and sexually transmitted diseases has reached all the population, and made it aware of the risks and produced changed behaviour, especially among prostitutes, homosexual men and drug addicts.

Sexual behaviour and sexually transmitted diseases in Dutch marines and naval personnel on a United Nations mission in Cambodia.

OBJECTIVES: To determine the sexual risk behaviour and the incidence of sexually transmitted diseases (STD) among Dutch marines and naval personnel during a United Nations (UN) deployment. METHODS: Surveillance by post deployment questionnaire, administered to 2289 persons in three successive battalions who served for 6 months on a UN deployment in Cambodia during June 1992-November 1993. On site the medical history of all individuals was kept up to date in a database. All personnel received extra education on STD prevention prior to deployment. Condoms were freely obtainable during deployment. RESULTS: 1885 persons (82%) handed in the questionnaire of whom 842 (45%) reported to have had sexual contacts with prostitutes or local population. Being younger and single were independent risk factors for having contact. Out of these 842 persons, 750 (89.1%) reported condom use at all times, while 82 (9.7%) reported inconsistent use and 10 persons (1.2%) reported not to have used condoms. Risk factors for inconsistent and non use were being 40 years or older and a higher number of contacts. From the 832 (750 + 82) condom users, 248 (30%) reported condom failure. Risk factors for failure were: inconsistent condom use, having had more than six contacts and being in the second battalion. The patient recording database showed 43 STD cases registered in the total population of 2289 persons (1.9%). CONCLUSIONS: A low STD incidence was found despite a considerable number of reported sexual contacts. The reported condom use was high but the failure rate was considerable and needs further attention.

Surveillance of antibiotic resistance in Neisseria gonorrhoeae in The Netherlands, 1977-95.

OBJECTIVE: To evaluate the prevalence and epidemiology of penicillinase producing Neisseria gonorrhoeae (PPNG) and tetracycline resistant N gonorrhoeae (TRNG) in the period 1977-95 in the Netherlands. To compare auxotypes, serovars, and antibiograms of PPNG, non-PPNG, and TRNG. To identify determinants in patient characteristics for the epidemic spread of TRNG/PPNG. METHODS: With respect to the national gonococcal surveillance all PPNG isolates from 30 laboratories over the country in 1977-90 and all gonococcal isolates from five sentinel laboratories (during 1 month per quarter) in 1991-5 were collected. Isolates were auxotyped and serotyped, the susceptibility for various antibiotics was tested and plasmid contents were evaluated. Additional data on PPNG infected individuals were collected retrospectively during a microepidemic of TRNG/PPNG. Univariate and multivariate analyses were performed to identify risk factors for TRNG/PPNG infections. RESULTS: In 1995 an overall high prevalence of PPNG infection (27%) and TRNG among PPNG infection (24%) was found in the Netherlands. Importantly, PPNG were found to have higher MICs for ceftriaxone and ciprofloxacin than non-PPNG; clinically relevant resistance to these antibiotics (or related agents) may emerge first among these strains. The observed diversity of strains (123 auxo/serovar classes since 1988) indicates a continuous introduction of new strains into the community. The epidemic increase of TRNG/PPNG was mainly caused by A/S classes NR/1B-6, PRO/1A-3, and PRO/1A-6, suggesting a clonal spread of a few strains; the rapid spread was associated with transmission in high risk individuals (that is, prostitutes and their clients). CONCLUSION: The prevalence of PPNG in the Netherlands remains high and reduced sensitivity to other antimicrobials was detected among the PPNG strains. This underlines the necessity for a continuous national surveillance of resistance in gonococci including limited epidemiological information.

Evaluation of a targeted HIV prevention programme among female commercial sex workers in the south of Thailand.

OBJECTIVE: To evaluate a targeted HIV prevention programme among female commercial sex workers (CSWs) in the south of Thailand. SUBJECTS AND METHODS: A pretest-post-test comparison group study was carried out in Sungai Kolok and Betong between June and December 1994. In June 408 CSWs were entered in Sungai Kolok (the intervention area) and 343 CSWs were enrolled in Betong (the comparison area). In December 1994, 416 women were enrolled in Sungai Kolok and 342 in Betong. Of these women 37% (n = 283) also participated in the June survey. All women completed an oral interview and blood samples were collected for HIV serology. The intervention programme consisted of an informational and educational campaign and peer educator training. RESULTS: Increase in knowledge and perceived vulnerability was more pronounced in the intervention area but did not translate into a greater increase in condom use. Refusal of customers unwilling to use a condom and manager support in doing so were the only factors independently related to positive changes in condom use. HIV prevalence (approximately 20%) and incidence (approximately 4.2 per 100 women years) were the same in both study locations. Women in the intervention area reported significantly fewer customers and income from sex work, possibly as a result of a coincidental police campaign to suppress (child) prostitution. CONCLUSIONS: HIV incidence among CSWs in the south of Thailand is still high. Prevention programmes should focus on improvement of negotiation and refusal skills and manager support in using condoms.

Sex in the city: sexual behaviour, societal change, and STDs in Saigon.

HIV infection is increasing among sex workers and injection drug users in southern Vietnam. Vietnamese sex workers returning from Cambodia are an important factor. This phase I growth stage is being accelerated by widespread prostitution and escalating heroin use. Sexually transmitted disease (STD) rates are significant in sex workers but low in the general population. STD epidemics in developing countries may not follow the dynamic topology that is common in developed countries. Vietnam has the potential for significant HIV and STD epidemics but also the capacity to respond to these threats.

Sexually transmitted infections in male clients of female sex workers in Benin: risk factors and reassessment of the leucocyte esterase dipstick for screening of urethral infections.

OBJECTIVES: (1) To assess risk factors for urethral infections with Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis among male clients of female sex workers (FSWs) in Benin; (2) to study the validity of LED testing of male urine samples compared to a highly sensitive gold standard (PCR) for the diagnosis of urethral infections with the organisms cited above. METHODS: Male clients of FSWs (n=404) were recruited on site at prostitution venues in Cotonou, Benin, between 28 May and 18 August 1998. A urine sample was obtained from each participant just before he visited the FSW, and tested immediately using a leucocyte esterase dipstick (LED) test. It was then tested for HIV using the Calypte EIA with western blot confirmation, and for C. trachomatis, N. gonorrhoeae, and T. vaginalis by PCR. After leaving the FSW's room, participants were interviewed about demographics, sexual behaviour, STI history and current symptoms and signs, and were examined for urethral discharge, genital ulcers, and inguinal lymphadenopathies. RESULTS: STI prevalences were: C. trachomatis, 2.7%; N. gonorrhoeae, 5.4%; either chlamydia or gonorrhoea 7.7%; T. vaginalis 2.7%; HIV, 8.4%. Lack of condom use with FSWs and a history of STI were independently associated with C. trachomatis and/or N. gonorrhoeae infection. Over 80% of these infections were in asymptomatic subjects. The overall sensitivity, specificity, positive and negative predictive values of the LED test for detection of either C. trachomatis or N. gonorrhoeae were 48.4%, 94.9%, 44.1%, and 95.7%, respectively. In symptomatic participants (n=22), all these parameters were 100% while they were 47.4%, 94.7%, 37.5%, and 96.4% in asymptomatic men (n=304). CONCLUSIONS: Since most STIs are asymptomatic in this population, case finding programmes for gonorrhoea and chlamydia could be useful. The performance characteristics of the LED test in this study suggest that it could be useful to detect asymptomatic infection by either C. trachomatis or N. gonorrhoeae in high risk men.

Eugenics and American social history, 1880-1950.

Eugenics, the attempt to improve the human species socially through better breeding was a widespread and popular movement in the United States and Europe between 1910 and 1940. Eugenics was an attempt to use science (the newly discovered Mendelian laws of heredity) to solve social problems (crime, alcoholism, prostitution, rebelliousness), using trained experts. Eugenics gained much support from progressive reform thinkers, who sought to plan social development using expert knowledge in both the social and natural sciences. In eugenics, progressive reformers saw the opportunity to attack social problems efficiently by treating the cause (bad heredity) rather than the effect. Much of the impetus for social and economic reform came from class conflict in the period 1880-1930, resulting from industrialization, unemployment, working conditions, periodic depressions, and unionization. In response, the industrialist class adopted firmer measures of economic control (abandonment of laissez-faire principles), the principles of government regulation (interstate commerce, labor), and the cult of industrial efficiency. Eugenics was only one aspect of progressive reform, but as a scientific claim to explain the cause of social problems, it was a particularly powerful weapon in the arsenal of class conflict at the time.

Epidemiology of hepatitis A and E virus infection in Brazil.

This review has the objective to discuss the epidemiological aspects of the enterically transmitted hepatitis A and E in Brazil. The prevalence of hepatitis A varies greatly in different Brazilian regions, from 56% in South and Southeast to 93% in North region (Manaus, Amazon). Such differences are also found in different socioeconomic levels among age groups. A significantly higher prevalence was seen in the low socioeconomic group between 1-30 years. This difference is most striking in the first 10 years of age (23.5% vs 60.0%, high/middle vs low, respectively). Despite the improvements in sanitary conditions, hepatitis A is still endemic and outbreaks may occur. As an increasing proportion of the population is becoming susceptible to hepatitis A virus infection and as adult individuals may present more severe forms of the disease, the authors conclude that the implement of hepatitis A vaccination should be considered. Some Brazilian data have shown that the genotype found in our country were IA and IB. Isolates from this study were closely related genetically (or even identical) to isolates originating in other South American countries and overseas, providing firm evidence for epidemiological links between persons who travel to endemic areas. In spite of favorable environmental conditions, outbreaks of hepatitis E have never been reported in Brazil. Nevertheless, reports have demonstrated the evidence of anti-hepatitis E virus antibodies in some Brazilian regions. The seroprevalence of IgG anti-hepatitis E virus among normal populations shows positivities of 6.1% in gold-miners, 3.3% in general population, 2.0-7.5% in blood donors, 1.0% in pregnant women, and 4.5% in children, with no differences among regions. In populations at risk the prevalence of anti-hepatits E virus varies greatly. Among patients with acute non-A, non-B, non-C hepatitis 2.1% was detected in the Southeast to 29% in the Northeast, in 10.6% of acute non-A, non-B, non-C hepatitis relatives in the Amazon basin, in 12% of acute sporadic non-A non-B hepatitis patients in the Northeast, a co-infection with acute hepatitis A in 25 to 38% in the Northeast, in 14 to 18% among prostitutes and women considered at risk for human immunodeficiency virus in the Southeast, and in 12% of the intravenous drug users in the Southeast.

[Incidence of genital infections caused by herpes simplex virus type 1 (HSV-1) from 1995 to 2003].

INTRODUCTION: In recent years studies from various parts of the world have reported a significant increase in the number of genital infections caused by HSV-1, especially among women. METHODS: We report a study of genital infections caused by HSV-1 in our geographic area from 1995 to 2003. Genital samples were inoculated in the Vero cell line and cultures were stained by monoclonal antibodies against HSV-1 and HSV-2. RESULTS: During the study period, 263 samples were positive for herpesviruses: 146 for HSV-1 (55.5%) and 117 for HSV-2 (44.5%). The 20 HSV-1 isolated in the genital tract represented 7.6% of all the herpesviruses isolated in this study. Of the 146 HSV-1 isolated, 20 (13.7%) were obtained in genital samples, 15 (75%) in women and 5 (25%) in men (p < 0.005). Four men (80%) were homosexual. No patient, male or female, was infected with the HIV and none worked as prostitutes. CONCLUSIONS: The percentage of HSV-1 genital infections increased in the last year of the study (33%), especially among women from the general population. The herpesvirus isolated in these samples should be characterized, since, in general, HSV-1 does not usually develop latency or recurrent infections in this anatomical area.

Risk factors and seroprevalence of hepatitis B virus, hepatitis C virus, and human immunodeficiency virus infection in uzbekistan.

OBJECTIVES: The aim of this study was to elucidate the seroprevalence of hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV) infection in Uzbekistan and to explore whether there is a correlation between those blood-borne agents and socioeconomic risk factors. METHODS: One thousand nine hundred and eighteen subjects were studied. The subjects were divided into a low-risk group, a high-risk group and a patient group. Sera were tested for HBV surface antigen (HBsAg), anti-HCV, and anti-HIV. RESULTS: The seroprevalence of HBsAg, anti-HCV, and anti-HIV in the general population was 13.3, 13.1 and 0%, respectively. The anti-HCV infection rate was significantly higher in intravenous drug users (62.7%) than in prostitutes (9.2%), homosexuals (11.1%), and medical laboratory employees (12.5%) (p < 0.01). In the low-risk group, positivity for anti-HCV increased with age from 2.2% in the 15- to 20-year-olds up to the highest rate of 17.6% in the 31- to 40-year-olds; the positivity then decreased to 0% in the group over 60 years of age. In the high-risk group, the positivity for anti-HCV in the age groups under 40 years was approximately 30% and significantly higher than in the low-risk group (p < 0.01). Risk factors for transmission of HCV were medical treatment in the low-risk group, drug abuse in the high-risk group, and both in the patient group. CONCLUSIONS: This study demonstrates that the seroprevalence of HBV and HCV infection is high, whereas HIV infection is yet uncommon in Uzbekistan.

Cocaine use in Europe - a multi-centre study. Methodology and prevalence estimates.

An increase in the use of cocaine and crack in several parts of Europe has raised the question whether this trend is similar to that of the USA in the 1980s. However, research in the field of cocaine use in Europe has been only sporadic. Therefore, a European multi-centre and multi-modal project was designed to study specific aspects of cocaine and crack use in Europe, in order to develop guidelines for public health strategies. Data on prevalence rates were analysed for the general population and for specific subgroups. Despite large differences between countries in the prevalence of cocaine use in the general population, most countries show an increase in the last few years. The highest rate with a lifetime prevalence of 5.2% was found for the United Kingdom, although with a plateau effect around the year 2000. With regard to specific subgroups, three groups seem to show a higher prevalence than the general population: (1) youth, especially in the party scene; (2) socially marginalized groups, such as homeless and prostitutes or those found in open drug scenes; (3) opiate-dependent patients in maintenance treatment who additionally use cocaine. Specific strategies need to be developed to address problematic cocaine use in these subgroups.

Diagnosis and epidemiology of transfusion-associated human cytomegalovirus infection: recent developments.

OBJECTIVE: The prevention and diagnosis of transfusion-associated HCMV infection has to address different questions: Is the blood donor potentially infections? Is the transfused recipient undergoing an active primary or secondary infection? DATA SOURCES: International literature (Current Contents Life Sciences) and reports of our study-group. SELECTION CRITERIA: Original articles in English and German. RESULTS: Monocytes have been identified as the major site of latency of human cytomegalovirus (HCMV) in peripheral blood. High seropositivity rates are observed in polytransfused individuals, intravenous drug users, organ transplant recipients, maintenance hemodialysis patients, homo/bisexuals and prostitutes. Although, there have been important developments in order to improve the sensitivity of the ELISAs for the diagnosis of active HCMV infection, serologic testing often fails to detect IgM and IgA antibodies in immunocompromised patients. Rapid virus isolation, structural antigen detection and DNA amplification by PCR in peripheral blood monocytes have considerably improved diagnosis of acute HCMV infection in neonates, organ transplant recipients and AIDS patients. Due to the low correlation of HCMV DNA detection and HCMV disease, PCR testing is actually not recommended for the monitoring of high risk patients and screening of infectiosity of blood components. CONCLUSIONS: As a consequence numerous improvements in serological, virological and molecular methods, a more efficient prevention and diagnosis of transfusion-associated HCMV infection has become possible.

Infectious AIDS--stretching the germ theory beyond its limits.

The hypothesis that human immunodeficiency virus (HIV) causes AIDS was advanced in 1984, based only on circumstantial evidence. To this date, the primary evidence are correlations between the presence of antibody against HIV and AIDS. But these correlations are biased by proponents of the HIV hypothesis in favour of HIV. They ignore HIV-free AIDS and they base correlations on selected studies because there are no national HIV-AIDS statistics. The HIV-AIDS hypothesis has made the following predictions: (1) AIDS would 'explode' from the original risk groups into the general population via sexual transmission of HIV. (2) Health care workers would contract AIDS from their patients, scientists from propagating HIV, and prostitutes from their clients. (3) The 150 chimpanzees that have been experimentally inoculated with HIV, and the 15,000 American hemophiliacs who have been iatrogenically inoculated before 1984, would develop AIDS. (4) Antiviral immunity and vaccines would protect against AIDS. (5) HIV would cause AIDS by killing T-cells. (6) AIDS would occur only in people infected by HIV. But none of these predictions proved to be correct. Recent studies show that HIV is a passenger virus instead of the cause of AIDS: (1) AIDS occurs at unpredictable intervals after infection; (2) HIV may be active, passive, or totally absent from otherwise identical AIDS cases. Indeed, AIDS does not meet one of the classical criteria of infectious disease: (1) Equal distribution between the sexes; (2) disease following infection within days or weeks, the time microbes take to become either immunogenic or pathogenic or both; (3) the presence of a common active microbe. Therefore it is proposed that American and European AIDS is caused by the long-term consumption of recreational drugs and the anti-HIV drug AZT. This hypothesis is testable and provides a rational basis for AIDS control.

Testing for human immunodeficiency virus infection in patients with tuberculosis.

To investigate the utility of testing all tuberculosis patients for HIV infection in Los Angeles, we prospectively evaluated 183 hospitalized patients with acid-fast smear-positive tuberculosis who gave no history of HIV infection. HIV serologic testing was performed, and the presence of risk factors for HIV infection was assessed by interview and review of the medical record. Thirty-three patients (18%) were infected with HIV. Based on data obtained by interview, 124 (68%) of 183 patients had at least one risk factor for HIV infection. The most common risk factors were related to heterosexual transmission of HIV (prostitute contact, multiple sex partners, and a history of sexually transmitted disease). These risk factors were frequently not documented in the medical record. Among the 33 patients who were infected with HIV, 30 were identified by interviewing as having significant risk factors. We concluded that most tuberculosis patients in Los Angeles have risk factors for HIV infection and that systematic questioning does not identify risk factors in all HIV-infected tuberculosis patients. These data support current recommendations to screen all tuberculosis patients for HIV infection.

Diagnostic and other correlates of HIV risk behaviors in a probability sample of homeless adults.

OBJECTIVES: This study assessed the relationship between psychiatric disorders, including substance abuse and dependence, and risk behaviors for contracting HIV. METHODS: A probability sample of 218 homeless men and women were recruited from food programs and shelters assisting homeless individuals in an urban metropolitan community. Mood disorders, schizophrenia, and substance abuse and dependence diagnoses were assessed with the Diagnostic Interview Schedule (version 3A). Level of sexual activity and HIV risk behaviors (such as history of sexually transmitted diseases, ratio of protected sex, trading sex for money or drugs, sex with a prostitute, and sex under the influence of alcohol or drugs) also were measured. RESULTS: Substance abuse and dependence and the length of the homelessness episode at baseline were associated with the highest risk of engaging in HIV risk behaviors. However, there was no relationship between mood disorders, schizophrenia, and HIV risk behaviors. CONCLUSIONS: This study provides evidence that individuals who are homeless for extended periods and have a diagnosis of substance abuse or dependence may be especially vulnerable to engaging in risky sexual behaviors and contracting HIV. The findings highlight the importance of tailoring treatment programs to the specific needs of homeless individuals.

Characteristics of women forensic patients in a federal hospital.

Increased criminal activity among women has prompted greater interest in the mentally ill female offender. An analysis of 72 women forensic inpatients at St. Elizabeths Hospital in Washington, D.C., indicated the typical patient was black, unmarried, in her mid-30s, poorly educated, and diagnosed as schizophrenic. The authors examine some relationships between race, type of crime, drug use, institutional history, and age and the utility of such variables as predictors of adjustment. A comparison of the primary sample with a cohort of 72 patients admitted ten years earlier showed that admissions related to public-order and technical offenses such as prostitution, parole violations, and drug violations decreased from 50 to 12 per cent, while admissions related to crimes of violence rose by 17 per cent.

Pathways and cycles of runaways: a model for understanding repetitive runaway behavior.

Based on information provided by 149 runaways staying in a Canadian shelter, the authors developed a model that explains repititious running away as the result of youths' cognitive confusion and unrealistic beliefs. The majority of the youths, who had run away an average of 8.9 times, felt that the events that led them to run away were unpredictable, yet 54 percent blamed only themselves for what happened. The paper describes the pathways, cycles, and outcomes of running away; analyzes the relationship between the youths' experiences with prostitution, delinquency, and sexual and physical abuse and the length of time they had been away from home; summarizes the youths' reasons for running away; compares the beliefs of runaways with and without a history of sexual abuse; and discusses interventions.

Sexuality, pregnancy, and childrearing among women with schizophrenia-spectrum disorders.

OBJECTIVE: This study compared sexuality, reproduction, and childrearing characteristics of women with schizophrenia-spectrum disorders with those of women without serious mental illness. METHODS: A semistructured interview was given to 46 women meeting Research Diagnostic Criteria for schizophrenia or schizoaffective disorder and to 50 control subjects without major mental illness who were matched for age, race, education, employment status, and religion. RESULTS: Compared with the control subjects, the women with schizophrenic disorders had more lifetime sexual partners, were less likely to have a current partner, and were more likely to have been raped and to have engaged in prostitution. Despite being at high risk for HIV infection, as a group they were less likely to have been tested for HIV. They reported wanting sex less often than did control subjects and rated their physical and emotional satisfaction with sex lower. They had fewer planned pregnancies, more unwanted pregnancies, and more abortions and were more often victims of violence during pregnancy. They were more likely to have lost custody of children and to report that they were unable to meet their children's basic needs and less likely to have another caregiver helping them raise their children. Both groups reported high rates of substance abuse during pregnancy. CONCLUSIONS: Health care delivery systems could better meet the needs of women with severe mental illness by providing social skills training, family planning, and more consistent screening for pregnancy, HIV, and battering. In addition, barriers to care for pregnant women with severe mental illness and substance abuse should be reduced, and parenting training should be incorporated into psychosocial rehabilitation programs for mentally ill parents.
