Point-of-care management of urogenital Chlamydia trachomatis via Gram-stained smear analysis in male high-risk patients. Diagnostic accuracy and cost-effectiveness before and after changing the screening indication at the STI Clinic in Amsterdam.

OBJECTIVES: To measure the effect of changing the point-of-care (POC) testing algorithm of urogenital chlamydia for all male high-risk patients to those with only symptoms with respect to: diagnostic accuracy, loss to follow-up, correctly managed consultations and costs. METHODS: Retrospective comparison of the diagnostic accuracy and cost-effectiveness of Gram-stained urethral smear analysis for the POC management of urogenital Chlamydia trachomatis infections. Between 2008 and 2009 Gram-stained urethral smear analysis was offered to all men irrespective of symptoms; between 2010 and 2011 only to those with symptoms. The Aptima CT assay was the reference diagnostic test. RESULTS: The number of examined Gram-stained smears in the two periods was respectively 7185 (2008-2009 period) and 18,852 (2010-2011 period). The sensitivity of the Gram stain analysis was respectively 83.8% (95% CI 81.2% to 86.1%) and 91.0% (95% CI 89.5% to 92.3%) (p<0.001). The specificity was respectively 74.1% (95% CI 73.0% to 75.2%) and 53.1% (95% CI 51.8% to 54.4%) (p<0.001). The positive predictive value was low in both periods, respectively 31.7% (95% CI 29.8% to 33.6%) and 35.6% (95% CI 34.1% to 37.1%) (p=0.002), whereas the negative predictive value was high, respectively 97.0% (95% CI 96.4% to 97.4%) and 95.4% (95% CI 94.6% to 96.1%) (p=0.002). The loss to follow-up rate between 2008-2009 and 2010-2011 was, respectively, 1.8% (95% CI 1.0% to 2.9%) vs 2.3% (95% CI 1.7% to 3.0%) (p=0.36). There was a small difference in overtreatment, 68.0% (95% CI 66.0% to 69.8%) vs 64.1% (95% CI 62.6% to 65.5%) (p=0.001). The cost per correctly managed consultation was 14.3% lower in the 2010-2011 period (€94.31 vs €80.82). The percentage of delayed treated infections was significantly lower in the 2008-2009 period (10.5%) compared with the 2010-2011 period (22.8%) (p<0.001). CONCLUSIONS: With a high sensitivity in male high-risk patients, the Gram-stained urethral smear is a useful POC test to detect urogenital C. trachomatis. When offered only to men with urogenital symptoms the specificity decreases but the cost per correctly managed consultation is reduced with 14.3% without a significant difference in loss to follow-up but with a significantly higher rate of delayed treatment.

[Health assessment of newborns with congenital urinary malformation].

Improvement in diagnosis of prenatal congenital urinary malformations (CUM) resulted in increased detection of CUM cases among newborns. To facilitate medical care for CUM newborns, we have developed an objective method of CUM newborns' health assessment. We studied 40 case histories of newborns with prenatally detected CUM admitted to urological clinics (20 with diagnosis of poor health and 20 with moderate condition severity) and 40 CUM newborns examined outpatiently (moderate health hazard). The computer analysis of the available data has established 13 most informative diagnostic criteria: 4 sonographic criteria, 3 lab criteria and 6 physical exam criteria estimated by 4 points - from 0 to 4. The criteria were pooled to a table which was used as a scale to assess general health condition. After delivery, CUM newborn gets inpatient health assessment by a neonatologist using 13 criteria. According to the total score, the condition is assessed as satisfactory (0-5), moderately severe (6-11), severe ( > 12). Efficacy of such health assessment was proved in a population study of 312 prenatal CUM newborns. Grouping of such newborns helps design of programs of further examination and management.

An extra pair of eyes: do patients want a chaperone when having an anogenital examination?

BACKGROUND: Anogenital examinations can be embarrassing for patients and can leave clinicians open to accusations of professional misconduct. Little is known about the attitudes of patients in Australia towards the use of chaperones. METHODS: In 2006, we surveyed 480 patients attending two sexual health clinics in northern Sydney. Our aim was to determine their attitudes towards the use of chaperones for anogenital examinations. RESULTS: Of the 480, 58% were male and 42% female. Most women (64%) preferred a female examining clinician, whereas most men (68%) had no preference for gender of the examining clinician (P < 0.0001). While 32% of women wanted a chaperone if being examined by a male, 29% did not. Only 4% of women wanted a chaperone when being examined by a female. Only 1% of men wanted a chaperone irrespective of the sex of the examining clinician. Independent predictors of women wanting a chaperone with a male clinician were preference for a female clinician (OR 6.59, 2.48-17.5; P < 0.001) and preference for a female chaperone (OR 4.02, 1.44-11.2; P = 0.008). The majority of participants felt that they should be involved in the decision to have a chaperone. CONCLUSIONS: Although a substantial minority of women want a chaperone when being examined by a male, a similar proportion do not want a chaperone. If a woman requests a female clinician, she should be offered a chaperone if there is only a male examiner available. Further study is required to determine why some women want a chaperone and how to distinguish them from other women.

Australian sexual health practitioners' use of chaperones for genital examinations: a survey of attitudes and practice.

OBJECTIVES: To examine the current practice and attitudes of Australian sexual health practitioners towards the use of chaperones for genital examinations. METHODS: In July 2006, an anonymous, self-completed questionnaire was mailed to members of the Australasian Chapter of Sexual Health Medicine. RESULTS: Of the 166 questionnaires sent to practitioners, 110 (66%) were returned completed. Of the 110 respondents, only 9% and 19% reported that their clinic routinely provided chaperones for all male and female genital examinations, respectively. Among practitioners whose services did not offer chaperones routinely, chaperones were offered with a mean frequency of 19% for female examinations and 8% for male examinations (P = 0.01). Compared to female practitioners, significantly more male practitioners thought a chaperone was important for medico-legal purposes when examining females (72% v. 53%, P < 0.05). Compared to male practitioners, significantly more female practitioners thought a chaperone was sometimes important for patient support when examining male patients (52% v. 26%, P < 0.001). Only 39% (n = 18) of male practitioners and 36% (n = 23) of female practitioners felt that resources spent on chaperones were justified by the benefits they provided. CONCLUSIONS: Despite only a minority of practitioners offering chaperones to patients or using them during examinations, many feel they are important for medico-legal reasons and as support for the patient. Best practice may be for services to routinely offer a chaperone and record instances where an offer is declined. This provides patients with choice and practitioners with some level of protection.

Managing sexually transmitted infections in community sexual health clinics: an audit of a community service.

Traditional hospital-based genitourinary (GU) medicine services have been overwhelmed by the current sexual health crisis. In November 2001, the Community Sexual and Reproductive Health department in Lewisham, South East London started a treatment service for uncomplicated sexually transmitted infections (STI). An audit was conducted to evaluate the effectiveness of and demand for this service. Two years after its introduction the number of chlamydia tests increased by 94%, the number of men attending the service doubled, GU medicine referrals halved and the number of STI treatments had risen by 90%, mainly for chlamydia. Proposed national outcome standards were exceeded with treatment of 84% of chlamydia clients with a median delay of 14 days, partner notification documented in 88% of chlamydia treatments and 0.45 contacts per case of chlamydia treated. Community-based services can provide successful testing, treatment and partner notification for uncomplicated STI despite increasing demand and such services should be properly recognized, encouraged and financially supported.

Is syndromic management better than the current approach for treatment of STDs in China? Evaluation of the cost-effectiveness of syndromic management for male STD patients.

BACKGROUND: The syndromic treatment approach has not been evaluated in sexually transmitted disease (STD) clinics in China. GOAL: The goal was to evaluate and compare the validity and cost-effectiveness of syndromic management with current STD management for men in clinics in Hefei, China. STUDY DESIGN: Diagnostic accuracy, treatment appropriateness, costs, and effectiveness of current clinical procedures and syndromic management were compared for 406 men attending four STD clinics. RESULTS: A modified World Health Organization (WHO) syndromic algorithm for urethral discharge yielded 100% sensitivity and a 69% positive predictive value (PPV). A syndromic algorithm for genital ulcers correctly treated all syphilis patients, with a 25% PPV. The average cost (in US dollars) per correct treatment by the current approach was 323.48 dollars for urethritis and 85.65 dollars for syphilis. For the syndromic approach, the average cost per correct treatment was 3.15 dollars for urethritis and 13.54 dollars for syphilis. CONCLUSION: Syndromic management can provide better treatment for men with STDs at significantly lower cost in resource-poor settings such as China.

The clinical and economic consequences of screening young men for genital chlamydial infection.

BACKGROUND: Wide-scale application of urine-based screening of asymptomatic men for chlamydial infection has not been thoroughly assessed. GOAL: The goal was to compare clinical and economic consequences of three strategies: (1). no screening, (2). screening with ligase chain reaction (LCR) assay of urine, and (3). prescreening urine with a leukocyte esterase test (LE) and confirming positives with LCR. STUDY DESIGN: We used a decision analytic model. RESULTS: At a chlamydia prevalence of 5%, the no screening cost was US dollars 7.44 per man screened, resulting in 522 cases of pelvic inflammatory disease (PID) per 100000 men. LE-LCR was most cost-effective, preventing 242 cases of PID over no screening at an additional cost of US dollars 29.14 per male screened. The LCR strategy prevented 104 more cases of PID than LE-LCR but cost US dollars 22.62 more per male screened. For this to be more efficient than LE-LCR, the LCR assay cost needed to decline to

Assessment of seminiferous tubule function (anti-müllerian hormone).

Anti-müllerian hormone (AMH) is specifically produced by Sertoli cells in the male. The testes express a high level of AMH from early fetal life, driven by the transcription factors SOX9, SF1, WT1 and GATA4, until puberty, when AMH is downregulated by testosterone and meiosis. When androgen negative effect is absent, follicle-stimulating hormone increases the secretion of AMH. Serum AMH determination is useful in the evaluation of children with non-palpable gonads, with or without ambiguous genitalia. It signals the existence of functional testicular tissue and allows a distinction to be made between gonadal dysgenesis and dissociated tubular-interstitial dysfunction. Serum AMH is a useful marker in the follow-up of male patients with precocious puberty or hypogonadotrophic hypogonadism, as well as of patients with sex cord stromal tumours of the gonads. Finally, AMH determination on the seminal plasma of men with non-obstructive azoospermia may be used as a marker of the existence of testicular spermatozoa when intracytoplasmic sperm injection is considered.

Assessment in the diagnosis of male chronic genital tract infection.

Different methodologies have been proposed to interpret the microbiological findings associated with contaminating, indigenous microbiota of the anterior urethra. In order to solve the controversy related to the diagnosis of chronic seminal infections in asymptomatic young adults, the results applying Stamey and Meares' criteria were compared with those obtained when semen cultures were studied for significant bacteriospermia. A total of 218 consecutive asymptomatic male partners of infertile couples were evaluated by the four-specimen technique described by Stamey and Meares' with the addition of semen (SM). Infection was detected in 46% by SM, while semen cultures (SC) showed a prevalence of infection of 41%; 73 patients were positive by both criteria and 102 negative; 27 patients were positive by SM technique in prostate fluid while their semen cultures were negative; 16 patients had positive semen cultures and were considered negative by SM. The kappa statistic indicated a good degree of agreement between both methodologies (kappa = 0.61, z = 8.68, p < 0.001). The estimated risk of being considered negative attributable to the semen culture (27 patients) was 25% (attributable risk = gamma ac- = 0.2550), and of being considered positive attributable to the semen culture (16 patients) was 26% (gamma ac+ = 0.2579). The 95% confidence limits were estimated in 12 to 39%, and in 13 to 31%, respectively. In view of these results, to establish the diagnosis of chronic prostatitis, the addition of prostatic fluid or voided urine cultures after prostatic massage, must be performed. Semen culture confronted with first-voided urine avoid overestimating seminal infection.

The sensitivity of a syndromic management approach in detecting sexually transmitted diseases in patients at a public health clinic in Cape Town.

OBJECTIVES: To evaluate the sensitivity of a syndromic diagnostic procedure in detecting and treating sexually transmitted diseases (STDs) and genital tract infections (GTIs). METHODS: All new patients presenting at an STD clinic were sampled systematically by gender over a 6-week period. After the patient's clinical consultation, the clinical records were reviewed. Thereafter all patients were given a thorough genital examination by the research physician, and specimens were collected for laboratory investigations. In a retrospective simulation clinicians' syndromic diagnoses were validated against the laboratory findings, or for genital ulcer syndrome against the findings of the research physician. RESULTS: 170 men and 161 women were included in the sample. Ninety-five per cent of patients were black and the median age was 22 years for women and 26 years for men. In this setting, the Western Cape syndromic diagnostic procedure achieved reasonable levels of sensitivity in detecting Neisseria gonorrhoeae and Chlamydia trachomatis in men and women, and in detecting Trichomonas vaginalis and bacterial vaginosis in women. However, it was estimated to be only 36.4% sensitive in detecting genital ulcers in women, and between 0% and 12.3% sensitive in detecting Candida albicans. With syndromic management 8.2% of men and 32.9% of women would leave the clinic with at least one infection inadequately treated. CONCLUSIONS: Despite the introduction of syndromic protocols, it is likely that a proportion of STDs and GTIs are not being detected and treated owing to the high prevalence of multiple syndromes and mixed infections, both symptomatic and asymptomatic.

Evaluation of acute scrotum in the emergency department.

A 2-year retrospective review of 238 cases of acute scrotal pain encountered in a children's hospital emergency department is presented. The incidences of testicular torsion, torsion of a testicular appendage, and epididymitis were 16%, 46%, and 35%, respectively. Testicular salvage was critically dependent on the interval between onset of pain and surgical intervention. No testis likely to have been viable at the time of presentation was "lost." The diagnostic error rate on first encounter was 7%, resulting in 10 negative scrotal explorations. With the exception of cases of far-advanced necrotic testes, both color Doppler ultrasound and radioisotope imaging were highly specific diagnostic modalities. Thirty-nine percent of the children with epididymitis who underwent investigation were found to have either structural or functional urinary tract abnormalities. Noninvasive urodynamic studies appear to be useful screening modalities in older children with epididymitis.
