Reactive arthritis in patients attending an urban sexually transmitted diseases clinic

OBJECTIVE: To assess the prevalence, clinical manifestations, associated genital infections, and HLA associations of reactive arthritis (ReA) among patients attending an urban sexually transmitted diseases (STD) clinic. METHODS: Using a standardized questionnaire, 271 consecutive adults, primarily black, with possible or proven Chlamydia trachomatis genital infection were screened for symptoms of ReA. A followup questionnaire was administered 6 weeks later by mail. Patients who reported at least 1 symptom were evaluated by a rheumatologist. HLA-B typing was performed on patients with objective ReA features. RESULTS: Nine of 217 patients (4.1%) with genital infection/inflammation had objective ReA features. Chlamydial or nongonococcal STD syndromes were diagnosed in 8 of these 9 patients (88%). Genital infection/inflammation was asymptomatic in 78% of patients with ReA features. HLA-B27 or other B7-cross-reactive group antigens were not associated with the occurrence of ReA. CONCLUSION: Nongonococcal genital infections, often asymptomatic, can trigger a relatively mild ReA in a larger number of exposed patients than previously thought, irrespective of the individual's HLA status.     

Susceptibility to vaccine-preventable diseases in a sexually transmitted disease clinic population

OBJECTIVE: To determine whether general practitioners (GPs) had received Australian guidelines on early detection, screening and surveillance for colorectal cancer or rectal bleeding, and whether their reported practice conformed with these guidelines. DESIGN: Cross-sectional postal survey of self-reported practice. PARTICIPANTS AND SETTING: 213 GPs in practice in the southern metropolitan area of Perth, Western Australia, were randomly selected from the Fremantle Regional Division of General Practice database and surveyed in March 1997. RESULTS: Replies were received from 155 (73%) of the GPs, and 110 reported receiving guidelines (from the Australian Gastroenterology Institute [AGI], 44; Gut Foundation of Australia [GFA], 40; others, 6; and not specified, 20). GPs who reported receiving guidelines were significantly more likely to screen for colorectal cancer (99/110; 90%) than those who reported not receiving guidelines (33/45; 73%) (P = 0.008). The commonest method to investigate people with identifiable risk factors for colorectal cancer was colonoscopy. Reported screening frequencies in asymptomatic patients with above-average risk (family history of colorectal cancer or past history of adenomatous polyps or colorectal cancer) were significantly higher than recommended by AGI and GFA guidelines (P < 0.05). Up to 24% of GPs investigated altered bowel habit or bleeding per rectum with faecal occult blood testing. CONCLUSIONS: Most GPs report having received guidelines. Reported screening frequency was higher than recommended for most above-average-risk patients, which will result in excessive consumption of resources without benefits for cancer prevention.     

Common genital dermatoses in male patients attending a public sexually transmitted disease clinic in Singapore

The male genitalia is a common site of various dermatoses. Male patients attending a sexually transmitted disease (STD) clinic may present with dermatoses that are not due to sexually transmitted diseases. A prospective study on 467 male patients attending a public STD clinic showed various dermatoses which were either anatomical variants (pearly penile papules in 67 patients [14.3%], sebaceous hyperplasia in 16 [3.4%], Tyson's glands in 32 [7%] and penile melanosis in 13 [2.8%]) or pathological conditions (balanitis in 45 [9.6%], eczema in 10 [2.1%], traumatic ulcers in 10 [2.1%], folliculitis and furunculosis in 8 [1.7%], scabietic nodules in 7 [1.5%], genital candidiasis in 7 [1.5%] and a few miscellaneous conditions). Fifty percent of the patients with Tyson's glands also had pearly penile papules. Most of the anatomical variants were incidental findings whereas most patients with the pathological dermatoses presented with these lesions. Unfamiliarity with these dermatoses may cause unnecessary anxiety to the patient and physician, resulting in inappropriate treatment.     

Sensation seeking, alcohol use, and sexual behaviors among sexually transmitted infection clinic patients in Cape Town, South Africa.

Alcohol use is associated with risks for HIV/AIDS. The association between alcohol and sexual risk may be accounted for by sensation seeking personality. However, sensation seeking in relation to substance use and HIV risk has not been examined in Africa. In this study, 292 men and 219 women receiving sexually transmitted infection (STI) diagnostic and treatment services in Cape Town, South Africa, completed anonymous behavioral surveys. Structural modeling was used to test a model of alcohol use and sensation seeking in relation to sexual risk behaviors. Results showed that sensation seeking and alcohol use in sexual contexts were related to HIV risks, controlling for gender and marital status. The association between sensation seeking and HIV risk was partly accounted for by alcohol use in proximity to sex. In contrast to studies conducted in the United States, sensation seeking was not related to alcohol-sex outcome expectancies. These findings suggest that alcohol use is an important HIV transmission risk factor for many STI clinic patients and that interventions for individuals who are characterized as sensation seekers are urgently needed in South Africa.

An assessment of care provided by a public sector STD clinic in Cape Town

A study was undertaken in a Cape Town public sector STD clinic to evaluate the content and quality of care provided since it has been recognized that appropriate improvements in the management of conventional sexually transmitted diseases (STDs), including provision of correct therapy, health education, condom promotion and partner notification, could result in a reduced incidence of HIV infection. Our objectives were to assess patients' needs for health education and to assess the quality of STD management in terms of health education, condom promotion, partner notification, the validity of the clinical diagnoses and the adequacy of the treatments prescribed. The study subjects were sampled systematically, according to their gender. Patients included in the study were given a standardized interview and their clinical records reviewed. Specimens were collected for laboratory investigations. For each STD detected, the treatment was defined as adequate if drugs currently known to be active against that infection were prescribed. One hundred and seventy men and 161 women were included in the study (median age: females 22 years, males 26 years). While almost all patients believed their STD may have been caused by unprotected sexual intercourse, many also believed it may have been caused by other factors, such as bewitchment with traditional medicine. Only 21% of male and 37% of female patients received any education about STD transmission during the clinic visit, and only 25% of male and 36% of female patients received education about condom use. As a result of the low sensitivity of the clinicians' diagnoses, 16% of men and 61% of women left the clinic with at least one infection inadequately treated. The majority of patients were not receiving education for the prevention of STDs including HIV. Many were not receiving adequate treatment for their infections. The introduction of a syndromic management protocol in this setting would substantially reduce the proportion of inadequately-treated patients. However, syndromic protocols, and the means by which they are implemented, need to take into account problems with the clinical detection of genital ulcerative disease and candidiasis in women.     

Genital ulcer disease in patients attending a public sexually transmitted disease clinic in Singapore: an epidemiologic study

Genital ulcer disease forms about 10% of all sexually transmitted diseases (STDs) in Singapore. In this retrospective study of 531 cases of genital ulcer disease presenting at the Department of STD Control, 91.6% were due to venereal causes and 8.4% were due to non-venereal causes. The venereal causes of genital ulcers were found to be genital herpes (71.5%), chancroid (15.8%), primary syphilis (3.4%) and lymphogranuloma venereum (1%). The non-venereal causes were mainly trauma, drug eruptions or were non-specific in nature. The peak incidence in both sexes occurred in the 20-39 year age group. Males outnumbered females by a ratio of 5.8:1. The ethnic distribution showed an under-representation of Malays relative to the racial makeup of the general population, reflecting perhaps a protective effect conferred by circumcision from genital ulcer diseases or a lower health-risk sexual behaviour in this ethnic group. The accuracy of initial clinical diagnosis was low indicating the need for laboratory investigations to establish accurate aetiologic diagnosis. Commercial sex workers were the main source of infection in males, highlighting the continued need to educate, screen and effectively treat this high risk group.     

HIV and other sexually transmitted diseases at a rural hospital in Zimbabwe

OBJECTIVE: To define the epidemiological characteristics of STD patients attending an outpatient clinic in rural Zimbabwe, to examine the aetiologic agents causing infection and to determine their relationship with HIV infection. SUBJECTS: 319 men and 146 women, making a sample of about 7% all patients attending an STD clinic during the 3 month study period. Microbiological data were collected from 104 men and 72 women selected randomly from these. Pregnant women were excluded and patients who had received antibiotics within the previous 14 days were excluded from the microbiology sub-sample. SETTING: An outpatient STD clinic at a District Hospital on a major truck route about 300 km north of the capital, Harare. METHODS: All new patients attending the clinic during a 3 month period were enrolled for clinical and epidemiological investigations using a standard procedure. Specimens for microbiological investigation were taken from every second patient seen on the first three days of each week. RESULTS: The typical patient was male (m:f ratio 2.2) aged 20-29 years (68% patients), not married (56% men) and in paid employment (66% men vs. 27% for the district). In men the most common presenting feature was genital ulceration, while in women, discharges were more common. Genital warts were noted frequently in both sexes. In the sub-sample examined microbiologically, H ducreyi was isolated from 46% ulcers clinically diagnosed as chancroid, and motile spirochaetes were detected in 25% painless ulcers. Neither of these were detected in ulcers in women, but HSV antigen was found as frequently in ulcers from men (19%) as from women (17%). In patients with genital discharges, gonococcal infection occurred in 64% men and 17% women, while T vaginalis was isolated from 39% women and only 8% men. Over 60% gonococcal isolates were PPNG, and 18% showed in vitro resistance to tetracycline. Yeasts, mainly C albicans were isolated from 42% women with a discharge and 25% women with ulcers. In men the presence of yeasts was associated with superficial ulceration and itchiness of the glans. Positive HIV-1 serology was found in 64% patients. There was no statistical association with current genital ulcers, though there was an association with previous STD episodes and particularly with serological evidence of syphilis. Apart from yeasts, there was no association between positive HIV-1 serology and the presence of pathogens in the genital tract. CONCLUSIONS: The high prevalence of HIV-1 antibodies in STD patients in Karoi suggests integration of STD and AIDS control programmes to be a necessity. Since paid employment was a common feature of both STD clinic attendance and HIV-1 seropositivity, these programmes may be effectively directed through the work place.     

Human immunodeficiency virus-1 infection among patients with sexually transmitted diseases in Bombay

Modern neuro-imaging caused a renewed interest in endoscopic techniques. Several indications for stereotactic endoscopy are illustrated. A prototype of a new four channel endoscope is used. Lesions in the posterior part of the third ventricle an even the fourth ventricle are reachable for biopsy. Cystic intra- or paraventricular lesions can be approached stereotactically and treated. Continuous rinsing is mandatory to preserve a clear vision.     

Factors associated with appropriate physician management of sexually transmitted diseases in an urban Canadian center

BACKGROUND AND OBJECTIVES: To explore physicians' management of selected sexually transmitted diseases (STDs), because previous studies suggest that physicians' management practices could be improved. GOALS: To determine the estimated annual incidence of STD seen by family/general practitioners (FPs), gynecologists (GYNs) and urologists (UROLs), adequacy of STD management practices, and any associations with demographic and other characteristics. STUDY DESIGN: A self-administered questionnaire was mailed to GYNs, UROLs, and a random sample of FPs in Hamilton, Ontario. RESULTS: Eighty-one of 102 (79.4%) FPs, 27 of 32 (84.4%) GYNs, and 7 of 8 (87.5%) UROLs responded. Vaginitis, male urethritis, and genital warts in women were the most frequently observed STDs. The treatment of bacterial vaginosis and pelvic inflammatory disease were most frequently at variance with published guidelines. CONCLUSIONS: Deficiencies exist in physicians' management of both common and potentially serious STD problems.     

Behaviors of heterosexual sexually, transmitted disease clinic patients with sex partners at increased risk for human immunodeficiency virus infection

BACKGROUND AND OBJECTIVES: From March 1989 through December 1992, the Centers for Disease Control and Prevention conducted annual, voluntary surveys of human immunodeficiency virus (HIV) risk behavior in sentinel sexually transmitted disease (STD) clinics in 25 cities in the United States. GOAL: Describe behaviors of heterosexual participants who reported as their only risk for HIV infection sexual contact with persons at increased risk for HIV. STUDY DESIGN: Participants responded to a standard questionnaire that collected demographic data and medical, drug use, and sexual histories. RESULTS: Sex with an injection drug user was the most common risk behavior. Fewer than 5% of participants always used condoms in the preceding year; 38% never used condoms. Multivariate analyses identified three independent predictors of HIV infection in men: living in the Northeast (odds ratio [OR] = 3.6; P < 0.001), sex with an HIV-infected woman (OR = 3.6; P < 0.01), and black race (OR = 2.7; P < 0.01). For women, sex with an HIV-infected man was the strongest predictor (OR = 12.0; P < 0.001) followed by Northeast residence (OR = 5.4; P < 0.001) and black race (OR = 3.4; P < 0.01). CONCLUSION: Sexually transmitted disease clinic patients throughout the United States knowingly engaged in sexual activities with partners at increased risk for HIV infection. HIV prevention activities need to be targeted to all sexually active persons, particularly in areas where injection drug use and HIV are prevalent.     

High prevalence of sexually transmitted diseases in women with urinary infections

OBJECTIVE: To determine the prevalence and factors associated with unrecognized sexually transmitted diseases (STDs) in women who had pelvic examinations and were subsequently released from the ED with a sole diagnosis of urinary tract infection (UTI). METHODS: A 3-month retrospective chart review was performed in an urban teaching hospital ED (> 70,000 visits/year). Women aged 12-45 years who had pelvic examinations and were released from the ED with a sole diagnosis of UTI were included. Patient complaints, physical findings, and laboratory results were reviewed. Laboratory evaluations included the complete blood count, urinalysis, urine pregnancy test, and cervical cultures for Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas. RESULTS: Of the 94 women who met study criteria, 53% had proven STDs (19% N. gonorrhoeae, 22% C. trachomatis, 33% Trichomonas). There was no difference between the patients with positive and negative tests for STDs with regard to complaints, physical findings, and laboratory results (all p > 0.05). CONCLUSIONS: Women undergoing pelvic examinations who are subsequently released from this urban ED with the diagnosis of UTI have a high (> 50%) prevalence of occult STDs. No complaint, physical finding, or laboratory result reviewed was associated with the risk of an STD. Consideration should be given to empirical antibiotic therapy in similar urban populations.     

Knowledge about AIDS and follow-up compliance in patients attending a sexually transmitted disease clinic in the highlands of Papua New Guinea

In a survey of 300 consecutive new attenders at the Porgera Health Centre Sexually Transmitted Disease Clinic information was obtained regarding knowledge about AIDS from male and female attenders. The differences between the sexes regarding a variety of socioeconomic variables, knowledge about AIDS and their compliance to follow-up appointments were studied as well as possible relationships between these social variables and the degrees of AIDS knowledge and compliance. Males tended to originate from further afield, be more educated, be either in salaried employment or not working at all, and be single as compared to females. They also admitted to more extramarital sexual contacts and received more adequate treatment. Knowledge about AIDS was also significantly higher amongst male attenders and in this group was correlated strongly with overall educational attainment and employment status but did not show any relationship with the number of extramarital contacts admitted to. Only 9% of the patients knew about condoms and their role in prevention. Follow-up compliance was generally poor, and not significantly higher in those with higher scores of knowledge about AIDS, but showed a relationship with the type of disease being treated and with the ultimate adequacy of treatment received.     

Prevention of sexually transmitted diseases. A model for overcoming barriers between managed care and public health. The IOM Workshop on the Role of Health Plans in STD Prevention

The United States Bureau of Labor Statistics' (BLS) annual survey of occupational injuries and illnesses (ASOII) is one of the most frequently utilized sources of data on national occupational morbidity. In 1992 the BLS introduced a new and expanded survey method that collects more detailed data on cases with days-away-from-work (DAW). However, to date, the BLS has not released any official publication that contains a comprehensive set of crosstabulated part-of-body (BP) and nature-of-injury (NOI) data. To improve the understanding of national DAW case morbidity estimates, the study presented here utilized a special data-call and data-reduction strategy to identify the leading ASOII BP-NOI combinations for DAW cases by frequency, incidence rate, and severity (median DAW) for 1994. The results indicated the significance of disability associated with discrete trauma (ie, resulting from instantaneous or sudden events) in the US workplace. While morbidity associated with back pain clearly continued as the most frequent type of disabling case, fractures at critical anatomical sites (eg, pelvic region, leg, shoulder) were responsible for the most lengthy disability absences from work in 1994. In some instances these findings were contrary to conclusions typically inferred from BLS publications.     

Improving quality of sexually transmitted disease case management in rural South Africa

OBJECTIVE: To measure quality of sexually transmitted disease (STD) syndromic case management and aspects of health-seeking behaviour at baseline in an intervention trial. SETTING: Ten rural primary care clinics, Hlabisa district, South Africa. DESIGN: Simulated patients (fieldworkers trained to present with STD syndromes) made a total of 44 clinic visits; 49 STD patients were interviewed when exiting clinics; facilities were assessed for availability of necessary equipment and drugs; 10 focus group discussions were held with staff; and STD syndrome surveillance was performed in all 10 clinics. RESULTS: A total of 9% of simulated patients were correctly managed (given correct drugs, plus condoms and partner notification cards), recommended drug treatment was given in only 41% of visits, and appropriate counselling was given in 48% of visits. Among patients leaving the clinic, although 39% waited over an hour to be seen and only 37% were consulted in private, all reported staff attitudes as satisfactory or good. Only six clinics had syndromic management protocols available, three reported intermittent drug shortages, and seven lacked partner notification cards. Focus group discussions revealed good staff knowledge about STD, but showed lack of training in syndromic management and low morale. Surveillance data showed that while 75% of those presenting for care did so within 1 week of symptom onset, 27% had been treated for an STD in the preceding 3 months, and only 6% of those treated were contacts. CONCLUSIONS: Quality of STD case management was poor despite good staff knowledge and availability of most essential resources. An intervention comprising staff training and STD syndrome packets has been designed to improve quality of case management.     

Evaluation of the Biostar Chlamydia OIA assay with specimens from women attending a sexually transmitted disease clinic

Chlamydia trachomatis infections are the most prevalent sexually transmitted diseases (STDs) in the United States. In acute-care settings such as clinics and emergency rooms, a desirable chlamydia screening assay should exhibit good sensitivity and good specificity and should provide test results while the patient is still present. The Biostar Chlamydia OIA (Biostar, Inc., Boulder, Colo.) is an optical immunoassay (OIA) that provides test results in less than 30 min and that uses a test format that allows office-based testing. This assay is performed entirely at room temperature without the need for rotators or other specialized equipment. The goal of this study was to compare the performance of the Biostar Chlamydia OIA for the detection of C. trachomatis with the performance of cell culture, direct fluorescent-antibody (DFA) assay (Syva MicroTrak; Syva Co., Palo Alto, Calif.), and PCR (Roche Amplicor Chlamydia trachomatis; Roche, Branchburg, N.J.) for the detection of C. trachomatis infections in women attending an urban STD clinic. For calculations of relative test performance (sensitivity, specificity, and positive and negative predictive values), patient specimens that yielded positive results by two or more of the four assays (cell culture, DFA assay, PCR, and OIA) were classified as "true infections." By these criteria, 42 of 306 total specimens were classified as positive for C. trachomatis (positive prevalence, 13.7%), 11 (3.6%; 10 by PCR and 1 by DFA assay) were positive by a single assay, and 253 (82.7%) were negative by all four tests. All culture-positive specimens were also positive by at least one other assay. Among the culture-negative specimens, 14(5%) specimens were positive by two of the three non-culture-based assays used. By using the criterion that positivity by at least two of the tests indicated a true infection,the relative sensitivities were as follows: culture and PCR, 92.9% each; Biostar Chlamydia OIA, 73.8%; and DFA assay, 59.5%.     

Violence and associated high-risk health behavior in adolescents. Substance abuse, sexually transmitted diseases, and pregnancy of adolescents

The intricate relationship between the social and health behaviors of persons of all ages has long been described. In adolescent health care, the risk-taking behaviors that are recognized in the areas of sexuality, drug and alcohol abuse, and violence need to be addressed. This article discusses adolescent risk behaviors and their relationships to violence. Health care providers need to consider these risk behaviors as they care for adolescents.     

Quality of case management of sexually transmitted diseases: comparison of the methods for assessing the performance of providers

Amiodarone is a widely used antiarrhythmic agent with highly variable therapeutic effects. These seem to be related, at least in part, to the pharmacokinetics of the drug and particularly to some features of its gastrointestinal absorption process. The drug exhibits physico-chemical properties highly suitable for diffusion across lipophilic absorbing membranes, but its low aqueous solubility can act as the rate limiting step for absorption, making the process erratic and variable. In order to gain an insight into the intestinal absorption mechanism of the drug and detect possible non-linearities, a series of experiments using a classical rat gut in situ preparation were carried out with three amiodarone hydrochloride solutions (10, 75, and 200 micrograms mL-1). A synthetic non-ionic surfactant, polysorbate 80, at supramicellar concentration (2 mM) was used as the drug solubilizer. Amiodarone was assayed in biological samples by HPLC using a rapid, sensitive technique that was validated. The amiodarone first-order absorption rate constants obtained in these conditions were similar. No significant differences between ka values were found. Amiodarone absorption was clearly identified as a passive diffusion process.
