[Precautions regarding prevent acute urethritis caused by Neisseria meningitidis in Japan]

In Japan, Neisseria meningitidis is not sufficiently recognized as the primary causative bacteria of sexually transmitted diseases (STDs) as the number of reported cases is small. Here, we summarize reports from 3 medical institutions, present clinical courses for each case, as well recommending precautions to prevent infection with this bacterium. Fourteen cases of N. meningitidis urethritis (MU) were admitted between April 2001 and June 2006. All patients were male, consulted a doctor after experiencing subjective symptoms, such as micturition pain and pus discharge, and were diagnosed as having urethritis using isolation culture methods. In 8 of the 14 cases, history of sexual contact in the preclinical stage was confirmed, and contact was with a commercial sex worker (CSW) in 6 of these cases. Many of these patients recalled oral contact. All strains indicated susceptibility to many drugs, and there were no problems with treatment. With regard to serotype, there were 10 cases of type Y, 1 case of type B, and 3 cases that were not classifiable or unidentified. In addition, among the 9 strains that were subjected to genotype identification, 7 strains were ST-23. The recent increase in availability of nucleic acid amplification methods has facilitated simultaneous detection of Neisseria gonorrhoeae and Chlamydia trachomatis. However, we fear that MU will become latent. For screening of urethritis, Gram staining and culture of urethral material must be performed to detect this disease. The relationship of the detected strain and its role in the pathogenesis of meningitis are uncertain, but its serotype and genotype are common in cases of meningitis. Thus, precautions are required to prevent spread of this bacterium.

Chlamydial and gonococcal infection in men without polymorphonuclear leukocytes on gram stain: implications for diagnostic approach and management

BACKGROUND

Gram stain is used to detect urethral inflammation, suggestive of infection, in men and guide therapeutic decisions. In the absence of signs, symptoms, or polymorphonuclear leukocytes (PMNs) on urethral Gram stain, treatment and sometimes testing is deferred.

GOAL

Determine the proportion of men with chlamydia or gonorrhea diagnosed by nucleic acid amplification testing (NAAT) or culture who lack Gram stain evidence of inflammation and compare their clinical characteristics to men with inflammation.

METHODS

Records from 2629 men presenting for routine sexually transmitted disease care with urethral PMN count and NAAT data were retrospectively analyzed. A subpopulation tested by NAAT and culture was analyzed. Men receiving antibiotics within the prior month or those reporting a sexual partner with trichomoniasis were excluded.

RESULTS

Among 2266 eligible men, 353 (16%) had chlamydia and 462 (20%) had gonorrhea. Among chlamydia-infected men, PMNs per oil-immersion field (oif) on Gram stain were > or =5 in 291 (82%), 1 to 4 in 20 (6%), and none in 42 (12%). In men with gonorrhea, PMNs/oif were > or =5 in 433 (94%), 1 to 4 in 6 (1%), and none in 23 (5%). Urethral symptoms, discharge, and/or > or =5 PMNs/oif were absent in 47 (13%) and 22 (5%) of chlamydial and gonococcal infections, respectively (including no PMNs/oif and 1-4 PMNs/oif). None of these 47 chlamydial-infected men and only 4 of 22 men with gonorrhea received therapy at the time of initial examination.

CONCLUSIONS

Twelve percent of chlamydial and 5% of gonococcal infections had no Gram stain evidence of urethral inflammation. Absence of symptoms and discharge is not uncommon in chlamydial infection detected by NAAT, and without testing, many infections will go untreated, furthering the possibility of complications or partner transmission.

Patient-Delivered Partner Treatment for Male Urethritis: A Randomized, Controlled Trial

BACKGROUND

Traditional partner referral for sexually transmitted diseases (STDs) is ineffective at assuring that partners are treated. Alternative methods are needed. We sought to determine whether patient-delivered partner treatment (PDPT) is better than 2 different methods of partner referral in providing antibiotic treatment to sex partners of men with urethritis and in reducing recurrence of Chlamydia trachomatis and Neisseria gonorrhoeae.

METHODS

Men who received a diagnosis of urethritis at a public STD clinic in New Orleans, Louisiana, during the period of December 2001 through March 2004 were randomly assigned according to the month of treatment for either standard partner referral (PR), booklet-enhanced partner referral (BEPR), or PDPT. At baseline and after 1 month, men were asked to provide information about each partner and were tested for C. trachomatis and N. gonorrhoeae.

RESULTS

Most enrolled index men (n = 977) were > 24 years of age (51.6%) and African American (95%) and had > or = 2 partners (68.3%). They reported information on 1991 partners, and 78.8% were reinterviewed 4-8 weeks later. Men in the PDPT arm were more likely than men in the BEPR and PR arms to report having seen their partners, having talked to their partners about the infection, having given the intervention to their partners, and having been told by their partners that the antibiotic treatment had been taken (55.8%, 45.6%, and 35.0%, respectively; P < .001). Of men who were reinterviewed, 37.5% agreed to follow-up testing for N. gonorrhoeae and C. trachomatis infection. Those tested were similar to those not tested with regard to the study variables measured. Among those tested, men in the PDPT and BEPR arms were less likely than those in the PR arm to test positive for C. trachomatis and/or N. gonorrhoeae (23.0%, 14.3%, and 42.7%, respectively; P < .001).

CONCLUSION

Among heterosexual men with urethritis, PDPT was better than standard partner referral for treatment of partners and prevention of recurrence of C. trachomatis or N. gonorrhoeae infection.

Der Einsatz von Gleitmitteln in der Urologie

Lubricants are used for catheterization and/or endoscopic maneuvers. "The lubricant" should guarantee sufficient lubrification of the urinary tract, good visualization during endoscopy, and excellent local anesthesia. Additionally, asepsis or reliable control of the local bacterial flora of the urethra should be ensured. Modern lubricants fulfil these recommendations; in addition, they provide therapeutic opportunities for local therapy, for instance, of non-gonococcal urethritis. The latest results show that there are a few lubricants with antimicrobiotic influence on MRSA (methicillin-resistant Staphylococcus aureus), which is of great importance because of the steady increase in MRSA-dependent infections.

[Pseudomonas aeruginosa infection presenting as gonorrhea]

A 68 year old man presented with urethritis and a purulent discharge, carrying the tentative diagnosis of gonorrhea. He had already been treated with multiple antibiotics. Microbiological investigation revealed Pseudomonas aeruginosa, a relatively frequent Gram-negative bacteria in hospitals, which can cause several nosocomial diseases such as pneumonia, wound infections and urogenital infections. Therapy can be difficult because of frequent antibiotic resistance. Guided by sensitivity studies, the patient was successfully treated with gyrase inhibitors. Pseudomonas aeruginosa-induced urogenital infections in ambulatory patients are extremely rare and usually not associated with a gonorrhea-like discharge.

Comparison of first void urine and urogenital swab specimens for detection of Mycoplasma genitalium and Chlamydia trachomatis by polymerase chain reaction in patients attending a sexually transmitted disease clinic

OBJECTIVE

The objective of this study was to compare urogenital swab specimens and first void urine (FVU) specimens from male and female patients at a sexually transmitted disease clinic for the detection of Mycoplasma genitalium and Chlamydia trachomatis infections using in-house, inhibitor-controlled polymerase chain reaction (PCR).

STUDY DESIGN

Urethral swabs and FVU were collected from 1856 men and 753 women who also had a cervical swab collected. A positive diagnosis of infection was made if any 1 of the specimens tested positive and were confirmed in a second PCR assay targeting independent genes.

RESULTS

M. genitalium DNA and C. trachomatis DNA were detected in 126 (6.8%) and 246 (13.3%) of the male sample sets and in 51 (6.8%) and 73 (9.7%) of the female specimen sets, respectively. Using our in-house PCR and sample preparation methods, FVU was found to be the most sensitive diagnostic specimen for both pathogens, but for optimal sensitivity, it should be supplemented with a cervical specimen in women. In a small subset of female FVUs, storage at -20 degrees C led to false-negative M. genitalium PCR results in 27% of specimens found positive when a sample preparation was performed before freezing. The age-specific prevalence of M. genitalium in men was almost constant between 18 and 45 years of age in contrast to C. trachomatis infections, which were more common in younger men.

CONCLUSION

Urine appeared to be a better diagnostic specimen than the urethral swab for M. genitalium and C. trachomatis detection by PCR in this cohort of sexually transmitted disease clinic attendees but should be supplemented with a cervical specimen in women.

Evaluation of extracts of Anthocleista djalonensis, Nauclea latifolia and Uvaria afzalii for activity against bacterial isolates from cases of non-gonococcal urethritis

Whole root preparations of three Nigerian medicinal plants, Anthocleista djalonensis, Nauclea latifolia and Uvaria afzalii, used traditionally in combination treatment of sexually transmitted diseases (STD), were extracted by maceration in ethanol, cold and hot water, respectively. The extracts were tested, by agar diffusion and macrobroth dilution methods, for activity against five strains of Staphylococcus aureus and two of Escherichia coli isolated from cases of STD and or urethritis. Four typed bacterial strains, S aureus ATCC 12600, Bacillus subtilis ATCC 6051, Pseudomonas aeruginosa ATCC 10145 and Escherichia coli ATCC 117755 were included as reference organisms. Ethanolic and cold-water extracts of Anthocliesta djalonensis exhibited activity against 9 and 7, respectively, of the 11 test organisms. They were bacteriostatic at minimum inhibitory concentrations (MIC) to the Gram positive strains but bactericidal to the Gram negative strains. Similar crude extracts of Uvaria afzalii showed bactericidal activity restricted to Gram positive (Staphylococcus aureus and Bacillus subtilis) strains. Nauclea latifolia extracts were bacteriostatic to both Gram positive and Gram negative strains. No test strain was susceptible to the hot water extracts of Nauclea latifolia but five and seven strains, were respectively susceptible to similar extracts of Anthocliesta djalonensis and Uvaria afzalii. Of the seven column chromatographic fractions of the ethanolic extract of Uvaria afzalii, F(ua-1) exhibited a bactericidal activity restricted to the Gram negative Escherichia coli strains, which were not susceptible to the crude extract. Fractions, F(ua-2), F(ua-3) and F(ua-4), like the crude extract, were bactericidal against the Gram positive strains only. Thus, partial purification seems to broaden the spectrum of activity and generally improve the potency of Uvaria afzalii. These results apparently justify the use of the three plants in treatment of STD.

Risk-taking and health-seeking behavior in men with a history of urethritis: is there a learning curve?

BACKGROUND AND OBJECTIVES

Studies addressing how past experience with sexually transmitted diseases (STD) influence health-seeking behaviors among at-risk men are few.

GOAL

The goal of this study was to determine whether health-seeking behaviors among men diagnosed with urethritis differ based on whether they report prior urethritis.

STUDY DESIGN

Male STD clinic attendees answered a questionnaire regarding their demographic, sexual, and health-seeking characteristics. The men were stratified based on whether they reported prior urethritis.

RESULTS

Of 466 men, 297 reported prior urethritis. Symptomatic men diagnosed with urethritis who reported prior urethritis did not recognize their symptoms as a possible STD earlier than those reporting no urethritis history; there was also no difference between the groups in their interval to presenting for care once symptoms were recognized as a possible STD. Furthermore, men with prior urethritis were as likely to engage in sex acts once they recognized their symptoms as a possible STD manifestation.

CONCLUSION

Compared with men without prior urethritis, men with urethritis symptoms who reported prior urethritis did not recognize symptoms earlier, alter health-seeking behavior, or curtail sexual activity.

Effectiveness of self-referral for male patients with urethral discharge attending a sexually transmitted disease clinic in China

BACKGROUND

Although partner notification (PN) has long been considered as an important component in sexually transmitted disease (STD) control programs and has been implemented in both developed and developing world, little information is known about the acceptability and efficacy of the strategy in China.

GOAL

The goal of this study was to assess the acceptability and outcome of self-referral for male patients with urethral discharge and to identify the characteristics associated with successful outcome based on a specialized STD clinic.

METHODS

From November 2001 to November 2002, 730 patients with confirmed urethral discharge were selected and asked by STD clinicians to bring their sexual contacts to treatment in a specialized STD clinic. The demographic and sexual characteristics of returned and unreturned index patients were analyzed. Univariate and multivariate analyses were applied to identify the characteristics associated with the outcome of self-referral.

RESULTS

Of 723 eligible index patients, 294 (40.7%) who returned for follow up identified 534 sexual partners and 429 (59.3%) who did not return for follow up identified 759 sexual partners. Of the total named 1293 sexual partners, 301 (23.3%) were notified by index male patients and 265 (20.5%) presented at the clinic. Of the 265 partners tested, 165 (62.3%) were infected with gonorrhea, chlamydia, or both; of them, 78 (47.3%) were asymptomatic. When the partnerships were married and steady, the informed rate was higher than that when the partnership was casual. For commercial sexual partnerships, only 1.8% of the partners were informed. In multivariate analysis, a prior STD history and condom use during the last sexual contact were associated with successful outcome of notification.

CONCLUSION

Patient referral was accepted both by STD clinic attendees and STD clinicians. The results of the study show that use of self-referral for partners of men with urethral discharge in a Chinese STD clinic was, with minimal effort, moderately successful. Further efforts to improve case-finding outcomes are warranted.

Risk behaviours associated with urethritis and genital ulcer disease in prison inmates, Sindh, Pakistan

We evaluated the epidemiological differences with respect to demographics, drug use and sexual behaviours associated with lifetime risk of urethritis, genital ulcer disease (GUD) and urethritis and GUD together among 3395 male prisoners in Sindh. Factors associated with urethritis and GUD alone were sex with multiple females, sex with men, and ethnicity. Additional factors associated with urethritis alone were sex with prostitutes, sex with partners having multiple partners and sex with partners believed to be injecting drugs. Behaviours associated with lifetime risk for urethritis and GUD together were sex with multiple females, sex with prostitutes, sex with men, sex with partners believed to be injecting drugs and ethnicity. These relationships were consistently stronger compared to urethritis or GUD alone.

Post-treatment sexual and prevention behaviours of adolescents with sexually transmitted infections

OBJECTIVE

To evaluate sexual behaviour (including abstinence), sex partner change, and condom use during the 3 month period following treatment for Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, or non-gonococcal urethritis.

METHODS

251 14-21 year old participants (83% female; 83% African-American) diagnosed with gonorrhoea, chlamydia, trichomonas, or non-gonococcal urethritis or sexual contacts of infected partners. Participants were clients of a public sexually transmitted diseases clinic or primary care adolescent clinics. Data were collected by structured interview at treatment, 1 month post-treatment, and 3 months post-treatment. At each visit, participants were asked about coital frequency and condom use for each recent partner. At 1 month, participants were asked when coitus occurred following treatment. At each follow up visit, sex partners were compared to partners named at treatment and classified as "same partner(s)," "new partner(s)," or both "same and new partner(s)."

RESULTS

Post-treatment abstinence was reported by 26% and 19% for the 1 month and 3 month visits, respectively. Abstinence was associated with greater likelihood of infection at enrolment although abstainers reported fewer lifetime STI and fewer lifetime sex partners. A substantial proportion of participants reported additional sexual contact with a previous partner. The average proportion of condom protected coital events increased from about 45% at enrolment to 64% at 1 month and 58% at 3 months (p<0.05). Higher levels were sustained for the 3 months following treatment.

CONCLUSIONS

Many adolescents adopt, at least temporarily, risk reduction behaviours such as abstinence or increased condom use. Sexual re-exposure to potentially untreated previous partners may increase risk of subsequent reinfection.

A recent increase in the incidence of male urethritis in France

BACKGROUND

At-risk sexual behaviors appear to have increased recently in France, possibly because of the reassuring efficacy of highly active antiretroviral treatments. The objective of this study was to assess the pattern of change.

GOAL

The goal was to analyze trends in the incidence of male urethritis, a marker of at-risk sexual behavior, between 1989 and 2000.

STUDY DESIGN

The general practitioners of the Sentinelles Network reported, through an online computer system, all cases of male urethritis they diagnosed, together with the patients' age, presence of discharge, sexual preference, history of sexually transmitted disease, prescriptions, and results of microbiologic findings.

RESULTS

After falling markedly between 1989 and 1995, the incidence of urethritis increased slightly in 1996 and then stabilized. The percentage of homosexual/bisexual men was higher among the cases than in the general population. Homosexual/bisexual men were younger than heterosexual men with urethritis; they were more likely to have a discharge and a history of sexually transmitted disease and had more sex partners. The main causative organisms were chlamydiae (18%) and Neisseria gonorrhoeae (13%).

CONCLUSION

The increasing incidence of urethritis in France calls for a readjustment of preventive strategies.

Diagnosis and imaging in urinary tract infections

The aim of imaging in urinary tract infection is to detect conditions that must be treated in order to avoid immediate deterioration or recurrences, and probable long-term kidney damage. In newborns identified with hydronephrosis during pregnancy or by neonatal screening, vesicoureteral reflux and renal scarring are congenital and not caused by infection. Most of these patients are male and the vesicoureteral reflux is of a higher grade than that detected in girls having had urinary tract infection. In children with urinary tract infection, several authors advocate a more selective policy and recommend imaging only in those children who are at risk for developing renal damage. In adult females no imaging is necessary in cystitis, whereas ultrasonography and plain films are recommended in acute pyelonephritis. Because uncomplicated urinary tract infection in men is rare, diagnostic evaluation including imaging should be started early in order to rule out complicating factors within the urinary tract. The role of imaging in prostatitis, vesiculitis, epididymitis and orchitis is primarily to rule out abscess formation, but also to exclude testicular malignancies.

Laser ablation of urethral hair

BACKGROUND AND OBJECTIVE

Two separate cases involving laser ablation of hair follicles in the neourethra are described.

STUDY DESIGN/MATERIALS AND METHODS

Urethral hair developed secondarily to free-flap urethroplasty for congenital urethral defects. In both cases, cystoscopic depilation with electrocautery fulguration was attempted on multiple occasions.

RESULTS

No improvement was seen; therefore, laser ablation was employed. Both patients remain free of regrowth at greater than one year of follow-up.

Mycoplasma genitalium in males with nongonococcal urethritis: prevalence and clinical efficacy of eradication

BACKGROUND

Mycoplasma genitalium is regarded as a potential pathogen of the human urogenital tract based on prevalence findings of several European studies.

GOAL

To determine the prevalence of M genitalium in urethral specimens of symptomatic patients with nongonococcal urethritis and from asymptomatic patients attending a sexually transmitted disease clinic in Milan, and to verify the clinical efficacy of M genitalium eradication by antibiotic treatment.

STUDY DESIGN

From May 1998 to late April 1999, a routine analysis for M genitalium by DNA amplification (polymerase chain reaction) was performed in patients attending the Institute of Dermatological Science in Milan. The authors examined urethral swabs from 178 symptomatic and 23 asymptomatic males. M genitalium-positive patients were clinically and microbiologically tested after treatment with either doxycycline or azithromycin.

RESULTS

Among males with nongonococcal urethritis, M genitalium was detected in 14.0% of patients as the only agent; in 15.1% of patients in association with Chlamydia trachomatis and/or Ureaplasma urealyticum; and in 1 asymptomatic patient. In all symptomatic M genitalium-positive patients, antibiotic treatment eradicated the infection and cured clinical symptoms.

CONCLUSION

These data reveal the high prevalence of M genitalium in symptomatic patients, the rarity of asymptomatic carriers, the high susceptibility to antibiotic treatment, and the clinical efficacy of M genitalium eradication. Moreover, data confirm the etiologic role of M genitalium in inflammatory processes of the human urogenital tract in the Mediterranean area.

To notify or not to notify: STD patients' perspectives of partner notification in Seattle

BACKGROUND AND OBJECTIVES

To obtain patients' perspectives on why only some partners are notified in partner-notification programs, the cornerstone of sexually transmitted disease (STD) control, although low proportions of partners are located and evaluated.

GOALS

To describe patterns of partner notification reported by persons with STD infection.

STUDY DESIGN

In-depth interviews conducted in Seattle with 60 heterosexual men and women with gonorrhea, chlamydial infection, or nongonoccocal urethritis, and 19 men with gonorrhea reporting sex with men (MSM) were tape recorded, transcribed verbatim, and content analyzed.

RESULTS

The typical notification pattern was to notify a main partner but not others. Least likely to be notified were partners perceived as transmitters, contacts preceding the onset of symptoms, the oral sex and anonymous contacts of MSM, one-time partners of men, and incarcerated and former partners of women. Fears among young heterosexual participants included gossip and violence (women). Fears among MSM included rejection.

CONCLUSIONS

Partner-notification programs should develop innovative approaches for partners perceived as transmitters, oral-sex only contacts of MSM, and contacts preceding symptom onset.

Prepackaged therapy for urethritis: the "MSTOP" experience in Cameroon

RATIONALE

The social marketing of STD treatment may be a strategy to increase the availability of effective therapy for urethritis in male patients.

OBJECTIVE

To evaluate a pilot project of social marketing of urethritis treatment packages. The project, initially designed for over the counter sale in private pharmacies, was finally restricted by national health authorities to primary healthcare settings in Yaoundé and Douala, Cameroon.

METHODS

Monthly sales of packages containing antibiotics, condoms, partner referral cards, and written information on STDs were monitored by the social marketing agency. Structured interviews were conducted with a sample of traceable patients who had consulted for urethritis. Structured interviews completed by focus group discussions were conducted among healthcare providers. Interview findings were further validated by a "mystery patient" survey, using surrogate patients. Lastly, 15 key informants among the decision markers involved in the project were interviewed in depth. Local independent consultants carried out the whole evaluation.

RESULTS

A total of 1392 treatment packages were sold in 10 months. Patients who had purchased the package reported high compliance with the treatment, with 99% taking the single dose of cefuroxime-axetil and 83% completing the course of doxycycline. 76% notified all or some partners, and 84% of those who had sex during treatment used condoms. In contrast, only 27% of trained healthcare providers prescribed "MSTOP". They questioned the omission of laboratory diagnosis, the selection of antibiotics, and the duration of therapy. Public health authorities were also sceptical about the choice of antibiotics and viewed the initial project as an overt encouragement of self medication.

CONCLUSIONS

Although the MSTOP project was not implemented in the way it had initially been designed, it highlighted the patients' interest in the product. Public health authorities in Cameroon should have been made aware of the limitations of the formal sector's response to STD care among men before over the counter sale of prepackaged therapy could have been considered as an alternative approach to inadequate self medication.

1998 guidelines for treatment of sexually transmitted diseases. Centers for Disease Control and Prevention

These guidelines for the treatment of patients who have sexually transmitted diseases (STDs) were developed by CDC staff members after consultation with a group of invited experts who met in Atlanta on February 10-12, 1997. The information in this report updates the "1993 Sexually Transmitted Diseases Treatment Guidelines" (MMWR 1993;42[no. RR-14]). Included are new recommendations for treatment of primary and recurrent genital herpes and management of pelvic inflammatory disease; a new patient-applied medication for treatment of genital warts; and a revised approach to the management of victims of sexual assault. Revised sections describe the evaluation of urethritis and the diagnostic evaluation of congenital syphilis. These guidelines also include expanded sections concerning STDs among infants, children, and pregnant women and the management of patients who have asymptomatic human immunodeficiency virus infection, genital warts, and genital herpes. Guidelines are provided for vaccine-preventable STDs, including recommendations for the use of hepatitis A and hepatitis B vaccines.

Risk factors for urethritis in heterosexual men. The role of fellatio and other sexual practices

BACKGROUND

Nonchlamydial nongonococcal urethritis (NGU) is a common sexually transmitted disease (STD) in heterosexual men. Prior studies have suggested that NGU may be acquired by insertive oral sex.

GOAL

To assess the association of oral sex and other sexual practices with nonchlamydial NGU in heterosexual men in order to better understand this syndrome and to guide its prevention and treatment. Risk factors for urethral gonorrhea and chlamydial infection were explored to contrast with NGU.

STUDY DESIGN

A retrospective case-control study was conducted among heterosexual men attending as STD clinic during 1993 and 1994. The study included 4,848 men who were sexually active within the prior 2 months and had urethral specimens obtained for Gram's stain, culture for Neisseria gonorrhoeae, and culture for Chlamydia trachomatis.

RESULTS

Insertive oral sex was not shown to be an independent risk factor for NGU. Independent predictors of nonchlamydial NGU by multivariate analysis included African-American race (odds ratio [OR] 3.71, 95% confidence interval [95% CI] 3.06 to 4.50) and having > or = two sex partners in the prior 2 months (OR 1.45, 95% CI 1.20 to 1.75). History of using condoms "always" was negatively associated with NGU (OR 0.59, 95% CI 0.43 to 0.79), gonorrhea (OR 0.31, 95% CI 0.17 to 0.56), and chlamydial infection (OR 0.67, 95% CI 0.44 to 1.03).

CONCLUSIONS

This study supports the sexually transmitted nature of nonchlamydial NGU but did not confirm an association with oral sex. However, the analysis was compromised by the rarity of insertive oral sex as patients' only sexual exposure. Consistent condom use protects against all causes of sexually acquired urethritis.

[Management of sexually transmissible diseases in an urban environment in Cameroon in 1992]

During the progress, in 1989, of a programme of social marketing of condoms in Cameroon, it was obvious that this approach should be supplemented by a similar programme for the management of STD's. Nine surveys were carried out in 1992 in Yaounde and Douala in the sexually most active male population (in the general community, at the workplace and in the leisure environment) in order to collect the basic data necessary for its implementation. Treatment essentially consists of mono-chemotherapy with drugs which are generally inefficient against the two principal etiologies of urethritis: Neisseria gonorrhoeae and Chlamydia trachomatis. The cost of treatment is considered excessive and leads to poor follow-up of the complete prescription. Simultaneous treatment of partners should be developed. All these data have been taken into account for the elaboration of a pilot programme which should be implemented in 1993.

[Control of retrograde urethrocystitis by converted Y-type urethral catheter]

A converted Y-type urethral catheter was used to curb retrograde urethrocystitis due to indwelling urethral catheter. Satisfactory results were obtained in 30 cases. Injection of 0.5% bromo-geramine (10 ml) into the bladder through the bypass tube killed effectively the bacteria in the indwelling catheter. The device had the functions of urine deposit, urine conduction, bladder and urethral washing as well as urine sample collection. The connection between indwelling urethral catheter and the conducting tube was not dismantled during the procedure. So it reduced the chance of extraneous contamination.

Screening for urethral infection in adolescent and young adult males

We evaluated the urinary leukocyte esterase (LE) dipstick as a predictor of a positive urethral culture for Neisseria gonorrhoeae and/or Chlamydia trachomatis in adolescent and young adult males. Sexual and sexually transmitted disease (STD) histories were also analyzed to determine predictors of infection. Subjects were recruited from sexually active males attending an adolescent medicine clinic. Patients were interviewed regarding presence of symptoms of urethritis and a variety of clinical variables. First-voided urine for LE dipstick and urethral swabs for gonorrhea and C. trachomatis cultures were obtained. One hundred patients (mean age, 19.2 years) were asymptomatic; 50 patients (mean age, 19.0 years) had symptoms of urethritis. In asymptomatic patients, the sensitivity, specificity, predictive value positive (PVP), and predictive value negative (PVN) of the LE dipstick were 0.31, 0.92, 0.57, and 0.90, respectively. These values were 0.66, 0.71, 0.76, and 0.60, respectively, in symptomatic patients. In each patient group the dipstick was more sensitive in detecting, and a better predictor of, a positive culture for gonorrhea than Chlamydia. LE dipstick results and clinical variables were evaluated as correlates of infection using stepwise logistic regression. A positive LE dipstick and four additional variables increased the probability of obtaining a positive culture for one or both organisms from symptomatic patients. These variables were the following: sexual contact in the previous month with a partner diagnosed as having a sexually transmitted disease, having ever used a condom, five or more lifetime sexual partners, and more than one sexual partner in the past month. Only a positive LE dipstick entered the model as a predictor of infection in asymptomatic patients.(ABSTRACT TRUNCATED AT 250 WORDS)

[Family practice management in urethritis. II. Comparison of clinical management to the protocol]

OBJECTIVE

To describe general practitioners' approach to and management of urethritis in men, and to compare this with a general practice protocol for urethritis.

DESIGN

Descriptive.

SETTING

General practices in Amsterdam.

PATIENTS AND METHODS

In 13 general practices in Amsterdam (23,510 patients, of whom 11,627 men) all episodes of urethritis in men (n = 55) were recorded during one year (complaints, medical management, diagnosis, medication, follow-up).

OUTCOME MEASURES

Description of the diagnostic and therapeutic approach and the course of episodes; rough comparison with the urethritis protocol.

RESULTS

In 25% the urine sediment was examined; other office tests were rarely performed. In 30 to 40% out of office microbiological tests were performed. In 50% of new diagnoses medication was underdosed, in some cases medication was wrong or not broad enough. In 25% explicit education was offered. In 22% new medication was given in the follow-up encounter.

CONCLUSIONS

(Comparison with protocol.) Urine sediment examination as an effective test is performed insufficiently often. Other office tests are rarely performed, in accordance with the protocol. Out of office microbiological tests are performed too often, judged by the few changes of diagnosis and the character of new medication in the follow-up. First treatment is often underdosed and sometimes wrong. First treatment should preferably be broad, adequately dosed and independent of out of office microbiology. Too little education is given concerning the risks of ascending infections in female partners and of HIV infection. The referral rate is very low. It is important to pay attention to the outcome of this study in (postgraduate) education for general practitioners, as they treat the vast majority of urethritis patients.

Comparison of urethral reaction to full silicone, hydrogen-coated and siliconised latex catheters

Indwelling urinary catheter may induce an inflammatory reaction or even stricture of the urethra. Catheter encrustation and urinary infection are other disadvantages associated with long-term catheterisation. In the present study, 77 male patients were catheterised randomly as part of their normal treatment with 1 of 3 different types of catheter: 22 siliconised latex, 28 hydrogel-coated latex and 27 full silicone catheters. The mean duration of catheterisation was 2.2 days. The urethral inflammatory reaction was assessed from cytological urethral swab specimens. Catheter encrustation was studied using scanning electron microscopic (SEM) analysis. The full silicone catheters induced the mildest degree of inflammation in the urethra, the percentage mean of inflammatory cells in smears being 20%. In both latex catheter groups the value was 36%. Neither the age of the patients nor the duration of catheterisation had any effect on the inflammatory reaction, which was more marked in patients with haemodynamic abnormalities. The hydrogel coating effectively prevented encrustation, while siliconised latex catheters were the least resistant to encrustation. The inflammatory reaction was variable in all patients. The use of urethral catheters should be restricted and suprapubic tubes should be used instead, particularly in patients with shock-like circulatory changes. By developing the biocompatibility and physical properties of urinary catheters, more compatible devices may be manufactured.

An analysis of and intervention in the sexual transmission of disease

Sexually transmitted diseases are a serious threat to the public health. Indeed, when an individual seeks medical treatment for a sexually transmitted disease, health authorities frequently attempt to identify, procure, and treat that individual's sexual contact(s). We conducted a comparative analysis of three alternative approaches to tracing the sexual partners of individuals diagnosed as having a sexually transmitted disease. The first approach involved counseling individuals (n = 27) infected with either gonorrhea or nongonococcal urethritis and exhorting them to procure their sexual partners for treatment. In addition to counseling, the second and third approaches involved distributing "occasion cards" for patients to use when informing sexual contacts of the need for treatment. Moreover, in the second approach, the counselor (a nurse or physician) informed infected patients (n = 19) that they and their partners could waive the $3 clinic fee contingent upon the partners seeking treatment within 1 week. In the third approach, the counselor asked infected persons (n = 19) to accept a follow-up telephone contact if their sexual partners failed to seek treatment within 1 week. The third approach was most effective. Ninety percent of the partners identified through this approach sought treatment, versus only about 60% of the partners in the other two conditions. The third approach was also the least expensive, costing about $2.95 to procure each partner for treatment.

Nongonococcal urethritis incidence has fallen at one university health service: are "safer sex" messages being heard?

The authors determined the incidence of nongonococcal urethritis (NGU) longitudinally in patients attending a university health service between August 1986, and May 1988. During this period, the authors observed a statistically significant fall in NGU incidence. This fall coincided with awareness of AIDS risks due to national and local media encouragement of condom use and avoidance of anonymous or promiscuous contacts. Although the authors have no evidence that these educational efforts resulted in the observed fall in NGU incidence, other examined, potentially intervening variables can not completely explain the observed changes. A fall in NGU incidence may be a marker for a more generally decreased risk of sexually transmitted diseases (STDs) in at least some men.

Epidemiological treatment of sexual contacts prevents recurrence of non-gonococcal urethritis

Of 98 male patients with non-gonococcal urethritis (NGU) who had regular female consorts who received concurrent epidemiological treatment, NGU recurred in four (16%) men whose treated partners were initially chlamydia positive and 20 (27%) men whose treated partners were initially chlamydia negative. Of 32 men whose regular female sexual partners refused to attend, 26 (77%) men suffered a recurrence of NGU. All study patients were selected because they were in monogamous relationships and returned to the clinic either because of a recurrence of NGU or for unrelated reasons at least 12 months after treatment. We recommend the routine epidemiological treatment of all sexual contacts of men with NGU.

Nonspecific urethritis in men

The epidemiology, diagnostic criteria, and etiology of nonspecific urethritis in men are discussed. Microbiological examinations have indicated that in the vast majority of these patients Chlamydia trachomatis and Ureaplasma urealyticum are the main causes for the disease. Treatment of the disorder has centered on the use of tetracyclinelike drugs, and with proper treatment cure can be obtained in the majority of patients.

Effect of epidemiological treatment of contacts in preventing recurrences of non-gonococcal urethritis

Clinical investigations of the usefulness of routine epidemiological treatment of sexual contacts of men with non-gonococcal urethritis (NGU) have produced conflicting results that could have been due to the selection of patients. In this study, which was undertaken in a provincial city, 100 men with untreated sexual partners and 100 demographically similar men with treated sexual partners were reviewed for recurrences of NGU over 12 months. Prolonged courses of tetracyclines were found to be beneficial particularly when the sexual partner gave positive results to tests for chlamydiae. There was, however, no clinical evidence that the men benefited from routine epidemiological treatment of their sexual partners.

Advantages of adding a course of tetracycline to single dose ampicillin and probenecid in the treatment of gonorrhoea

Chlamydia trachomatis was reisolated from 11 of 12 men with gonorrhoea who had initially yielded chlamydiae and who had been treated with ampicillin and probenecid (AMP) only, but from none of five such men treated with ampicillin and probenecid followed by tetracycline (AMPT). These results correlated with the absence of postgonococcal urethritis (PGU) in the group treated with AMPT. C trachomatis was isolated or reisolated from 20 of 25 women after treatment with AMP, compared with none of 14 women treated with AMPT. We recommend the addition of a course of tetracycline to the routine single dose treatment for gonorrhoea in men and women.

The effect of chemical intravaginal contraceptives and Betadine on

The purpose of this study was to find a barrier contraceptive agent capable of controlling infections and sexual transmission of Ureaplasma urealyticum from the female genital tract, especially to help reduce nongonococcal urethritis in males caused by this organism. Therefore, the in vitro antimicrobial activity of six intravaginal contraceptives and BetadineR against the eight serotypes of the organism was investigated. The results indicate that some of these contraceptives produce partial inhibition of the Ureaplasma at low dilutions, while BetadineR produces a ureaplasmacidal effect up to dilutions of 1:64. These effects appear not to be due primarily to the pH of these agents. Thus, some of these agents may have a potential role in controlling transmission of Ureaplasma urealyticum.

Treatment of uncomplicated gonorrhea with rosoxacin

In a randomized, double-blind, dose-ranging study, single oral doses of rosoxacin were used to treat 126 patients with uncomplicated genital or anorectal gonorrhea. Neisseria gonorrhoeae was eradicated from 5 (28%) of 18 men treated with 100 mg, compared with 101 (94%) of 108 men and women treated with 200 mg, 300 mg, or 400 mg (P less than 0.001). Susceptibility to rosoxacin was determined for 6 pretreatment gonococcal isolates from these patients and for 194 stored clinical isolates; 296 (98.7%) of these 300 isolates, including 10 strains of penicillinase-producing N. gonorrhaeae, required a minimal inhibitory concentration of less than or equal to 0.062 microgram/ml. Urethral or cervical infection with Chlamydia trachomatis coexisted with gonococcal infection in 14 (22%) of 63 patients and persisted in 7 of 10 patients treated with rosoxacin. Postgonococcal urethritis developed in 11 (34%) of 32 men who were monitored for 12 to 30 days. Sixty-four subjects (51%) developed transient dizziness, drowsiness, altered visual perceptions, or other symptoms suggestive of central nervous system dysfunction after treatment with rosoxacin, but these symptoms were not clearly dose related. Rosoxacin in doses of greater than or equal to 200 mg appears to be effective for single-dose treatment of uncomplicated gonorrhea, but further studies of its possible central nervous system toxicity are indicated.

A trial of minocycline given after exposure to prevent gonorrhea

In a prospective evaluation of antibiotic prophylaxis against gonorrhea, 1080 men were given 200 mg of oral minocycline or placebo after sexual intercourse with prostitutes in a Far Eastern port. Later, at sea, gonococcal infection was detected in 57 of 565 men given placebo and 24 of 515 men given minocycline (P less than 0.001). Minocycline prophylaxis completely prevented infection by gonococci susceptible to 0.75 microgram or less of tetracycline per milliliter, reduced the risk of infection or prolonged the incubation period in men exposed to gonococci susceptible to 1.0 to 2.0 micrograms per milliliter, but did not prevent infection or prolong incubation in men exposed to gonococci resistant to 2.0 micrograms. Minocycline did not increase the proportion of asymptomatic infections. Minocycline prophylaxis would probably have limited effectiveness as a public-health measure because of the tendency to select resistant gonococci.

A simple operation for postcoital urethrotrigonitis in women

Definitive treatment of postcoital urethrotrigonitis, or "honeymoon cystitis", as it is commonly called, has only been paid serious attention since 1967. It has been suggested (O'Donnell, 1959) that the introduction of bacteria into the urethra is more likely when the urethra assumes a relatively hypospadiac position during coitus. This is commonly associated with incomplete rupture of the hymen. Division of the anterior bridge of the hymen on either side of the external urethral meatus appears to be as effective as more complicated procedures in preventing ascending infection associated with coitus.

The condom and gonorrhoea

The use of the condom by male patients attending a clinic specialising in sexually transmitted diseases has been assessed over a period of six months. Condom users were divided into those who used them properly and invariably, and those who did not. In the group studied, correct use of the condom was associated with a significantly lower probability of acquiring gonorrhoea (P less than 0-001) and a significantly higher chance of there being no sexually transmitted disease diagnosed (P less than 0-0005). The diagnosis-rate of non-specific urethritis, however, did not differ among the groups.

Estrogen treatment of postmenopausal women. Benefits and risks

Estrogen treatment of postmenopausal women is effective in relieving the symptoms of vasomotor instability and urogenital atrophy; estrogen treatment is effective in preventing accelerated bone loss and osteoporosis in young women following castration, but in postmenopausal women aging is a more important determinant of accelerated bone loss than is decreased estrogen secretion. Low-dose estrogen treatment of postmenopausal women neither prevents nor increases the risk of arteriosclerotic cardiovascular disease or cerebral vascular disease. It cannot be definitively established that estrogen treatment of postmenopausal women causes an increased incidence of breast tumors, but it is clear that such treatment does not prevent these tumors. It is established that estrogen treatment of postmenopausal women increases the risk ratio of endometrial carcinoma.

Spectinomycin versus tetracycline for the treatment of gonorrhea

Spectinomycin and tetracycline are alternative drugs to penicillin in the treatment of gonorrhea. To compare the efficacy of these agents and their propensity to select resistant gonococci, we treated 4043 patients randomly with either 2 or 4 g of spectinomycin once or 9 g of oral tetracycline for four days. Minimum cure rate for anogenital gonorrhea was 94 per cent with either drug. Oropharyngeal infection responded poorly to spectinomycin in men, with failure of therapy in six of 11. Postgonococcal urethritis in men was less common after tetracycline than after spectinomycin (P less than 0.005). Spectinomycin failure was not related to drug resistance. Tetracycline failure correlated with resistance (P less than 0.0002); one fifth of the isolates resistant to 1.0 mug per milliter of tetracycline were not eradicated. For several reasons, including the appearance of beta-lactamase-producing gonococci, it is no longer clear that penicillin G is the "drug of choice" for gonorrhea. Spectinomycin and tetracycline are equally acceptable alternatives, each with distinct advantages and disadvantages.
