Primary mucinous adenocarcinoma of the urethra: A contemporary clinicopathologic analysis of 17 patients

Mucinous adenocarcinoma of the urethra is rare. Here we performed a contemporary clinicopathologic analysis of this entity in both male and female patients. All cases with secondary tumors involving the urethra were excluded. Clinicopathologic parameters and follow up was obtained. Seventeen patients were included in the study, 9/17 (53 %) male and 8/17 (47 %) female. The mean patient age was 68 years (range: 53-88 years). The majority (11/17, 65 %) of patients were African American, with an even greater incidence (7/8, 87 %) in female patients. In male patients, prostatic urethra was the most common part of the urethra (6/9, 67 %) where the tumor arose from. Immunohistochemical stains were performed in 11/17 (65 %) tumors and were positive for CK20 (11/11, 100 %), CDX2 (11/12, 92 %), CK7 (8/9, 88 %), GATA3 (3/8, 37 %) and negative for NKX3.1, PSA, p63, PAX8, and Beta-Catenin. In resection specimens, tumors were categorized as pT2 (3/11, 27 %), pT3 (1/11, 9 %), and pT4 (7/11, 64 %). Lymph node status was categorized as pN0 (6/9, 67 %), pN1 (1/9, 11 %), and pN2 (2/9, 22 %). Available follow up data showed 7/13 (54 %) patients developed recurrence after surgical resection and chemotherapy, of which 3/7 (43 %) died of widespread metastatic disease. It is critical for pathologists and urologic oncologists to be aware of this entity in both male and female patients in view of potential diagnostic pitfalls, prognosis, and therapeutic implications.

Mycoplasma genitalium: Key Information for the Primary Care Clinician

Mycoplasma genitalium (MG) is an emerging sexually transmitted infection, which appears to be a cause of urethritis and cervicitis and has been associated with pelvic inflammatory disease (PID), epididymitis, proctitis, infertility, complications during pregnancy, and human immunodeficiency virus (HIV) transmission. Three Food and Drug Administration (FDA) approved tests are available. Testing should be focused to avoid inappropriate antibiotic use. The Center of Disease Control and Prevention (CDC) guidelines recommend testing for persistent male urethritis, cervicitis, and proctitis and state that testing should be considered in cases of PID. Testing is also recommended for sexual contacts of patients with MG. Testing is not recommended in asymptomatic patients, including pregnant patients, who do not have a history of MG exposure. Although resistance-guided therapy is recommended, there are currently no FDA approved tests for MG macrolide resistance, and tests are not widely available in the United States. The CDC recommends 2-step treatment with doxycycline followed by azithromycin or moxifloxacin. Moxifloxacin is recommended if resistance testing is unavailable or testing demonstrates macrolide resistance..

Detection of blaCTX-M-15 in an integrative and conjugative element in four extensively drug-resistant Haemophilus parainfluenzae strains causing urethritis

Haemophilus parainfluenzae is a commensal organism with rising numbers of multidrug-resistant (MDR) strains. This pathogen is of increasing clinical relevance in urogenital infection. The aim of this work was to identify and characterise the molecular mechanisms of resistance associated with four cephalosporin-resistant H. parainfluenzae strains collected from patients with urethritis. Antimicrobial resistance was determined by microdilution following European Committee on Antimicrobial Susceptibility Testing criteria. Strains were then analysed by whole-genome sequencing to determine clonal relationship and the molecular basis of antimicrobial resistance. Finally, a phylogenetic analysis was performed on all urogenital MDR strains of H. parainfluenzae previously isolated in our hospital. All strains were resistant to β-lactams, macrolides, tetracycline, fluoroquinolones, chloramphenicol, cotrimoxazole, and aminoglycosides. The resistance profile was compatible with the presence of an extended-spectrum β-lactamase (ESBL). Whole-genome sequencing detected blaCTX-M-15 that conferred high minimum inhibitory concentrations to cephalosporins in two novel integrative and conjugative elements (ICEHpaHUB6 and ICEHpaHUB7) that also harboured a blaTEM-1 β-lactamase. This study shows a novel blaCTX-M-15 ESBL carried in an integrative conjugative element in four extensively drug-resistant H. parainfluenzae strains. This resistance determinant could be transmitted to other sexually transmitted pathogens and this is a cause for concern.

Clinical significance of isolation of Haemophilus no ducreyi in genital samples. Systematic review

INTRODUCTION AND OBJECTIVES

Currently, the microbiological diagnosis of genital infections is carried out with molecular methods, which allow the detection of less frequent etiological agents but with potential pathogenic importance, such as Haemophilus spp. The objective of this review is to analyse and highlight the clinical importance of the isolation of Haemophilus spp. in genital and rectal infections, excluding Haemophilus ducreyi.

MATERIAL AND METHODS

A systematic review was carried out based on an exhaustive search of the publications included in the MEDLINE database up to August 5, 2021, on the presence of Haemophilus spp. in genital and rectal infections, excluding H. ducreyi.

RESULTS

After reviewing what was described in the literature, Haemophilus spp. (excluding H. ducreyi: HSNOD) was detected in 2397 episodes of genital infection, the most frequently isolated species being H. influenzae and H. parainfluenzae. Most of the episodes (87,6%) are constituted by single isolation. There is a slight predominance in women (48,3%) where it can cause vaginitis, salpingitis, endometritis or complications during pregnancy. In men, the clinical picture usually corresponds to urethritis. Most of the samples correspond to vaginal and urethral exudates, with a minority representation at the rectal level (2.3%).

CONCLUSION

HSNOD plays a relevant pathogenic role in episodes of genital infection, so microbiological diagnostic protocols must include methods that allow their detection, as well as include them in the etiological spectrum of this type of clinical picture.

Update in Epidemiology and Management of Mycoplasma genitalium Infections

Mycoplasma genitalium is a frequent cause of urogenital syndromes in men and women and is associated with adverse sequelae in women. M genitalium also infects the rectum, and may cause proctitis, but rarely infects the pharynx. Diagnosis requires nucleic acid amplification testing. Antibiotic resistance is widespread: more than half of infections are resistant to macrolides and fluoroquinolone resistance is increasing. Resistance-guided therapy is recommended for symptomatic patients, involving initial treatment with doxycycline to reduce organism load followed by azithromycin for macrolide-sensitive infections or moxifloxacin for macrolide-resistant infections. Neither screening nor tests of cure are recommended in asymptomatic persons.

Periurethral abscess etiology, risk factors, treatment options, and outcomes: A systematic review

Objectives

This study aimed to describe patterns of presentation, etiology, risk factors, management, and treatment outcomes of periurethral abscesses using a systematic review framework.

Materials and methods

After prospective registration on the PROSPERO database (CRD42020193063), a systematic review of Web of Science, Embase, PubMed, and Cochrane scientific databases was performed. Articles published between 1900 and 2021 were considered. Extracted data included symptoms, etiology, medical history, investigations, treatment, and outcomes. Collated data were analyzed using univariate methods.

Results

Sixty articles met the inclusion criteria reporting on 270 patients (211 male, 59 female) with periurethral abscess. The most common clinical features were pain (41.5%), pyuria (41.5%), dysuria (38.5%), urinary frequency (32.3%), fever (25%), and a palpable mass (23%). Predisposing risk factors included the presence of a sexually transmitted infection or urinary tract infection (55.0%), urethral strictures (39.6%), and recent urethral instrumentation (18.7%). Management approaches included open incision and drainage (64.3%), conservative management with antibiotics (29.8%), and minimally invasive techniques (needle aspiration, endoscopic drainage). Time trend analysis of etiology revealed a decreased incidence of infection (sexually transmitted infection/urinary tract infection, human immunodeficiency virus) and higher incidence of diabetes mellitus and periurethral bulking injections in recent years.

Conclusions

Periurethral abscesses may display a wide range of clinical features. Presentation, risk factors and underlying etiology vary with sex. The optimal management technique is guided by abscess size. Open incision and drainage combined with antibiotics continues to be the mainstay of management. However, minimally invasive techniques are gaining favor. To the authors' knowledge, this is the first systematic appraisal and management algorithm for periurethral abscess.

[Primary care management of sexually transmitted infections (I). Epidemiology. Secreting syndrome]

These days sexually transmitted infections (STIs) are important public health problems not only due to their high prevalence, but also because they require early diagnosis and treatment to avoid complications. In recent years, there has been an exponential increase in cases of infections caused by Chlamydia trachomatis and gonococcus in the population under 25years of age. In addition, an increase in the incidence of syphilis and hepatitisC (HCV) has also been detected, especially in men who have sex with other men (MSM). Genital herpes continues to be the second most frequent STI in the world, behind condyloma acuminata, and the first cause of genital ulcer among Spain in the sexually active population. A decrease in reported HIV cases was observed during 2020, but almost half of these new cases had a late diagnosis (<350CD4cell/μL). Current guidelines recommend offering STI annual screening to populations at risk or more often depending on the risk. STIs can appear in the form of syndromes, such as secretory syndrome (urethritis, proctitis, and cervicitis) or ulcerated syndrome (ulcers). The STIs that can cause secretory syndrome are mainly caused by Neisseria gonorrhoeae and C.trachomatis, which co-infect up to 40% of cases, and also cause urethritis, cervicitis or proctitis depending on where they are located. Gonococcus has an incubation period of 2-7days and Chlamydia 2-6weeks, and they are diagnosed using PCR and/or culture (the last one only valid for gonococcus) of samples collected according to sexual activities. Empirical treatment to cover both germs will be accomplished with ceftriaxone, 1g single intramuscular dose plus doxycycline 100mg every 12h orally for 7days, or azithromycin 1g single dose orally (we will use azithromycin only if we suspect a poor compliance with treatment, difficulty in going to the control or in pregnancy). Likewise, whenever we diagnose an STI firstly, we must offer advice and health education in order to promote the adoption of safe sexual behaviours and the correct use of barrier methods. Secondly, we must also screen for other STIs (HIV, syphilis, hepatitisB, and hepatitisA andC depending on the risk), offer HBV and HAV vaccination if it is appropriate, and finally study and treat all sexual partners from the previous 3months.

[Neisseria meningitidis and the increase of oral sex. A case report]

Urethritis is an entity characterized by dysuria and purulent urethral discharge, generally acquired sexually. Neisseria gonorrhoeae is one of the most frequently responsible microorganisms. Neisseria meningitidis is a gram-negative diplococcus usually isolated in the pharynx, that occasionally causes meningococcal meningitis, being unusual it's isolation in the anogenital area where it could be a genitourinary pathogen. We present the case of a 25-years-old heterosexual male who, after a heterosexual intercourse with an occasional non-professional partner, including oral and vaginal sex, presented with symptoms of urethritis, orienting to a sexually transmitted infection. The bacteriological culture for N. gonorrhoeae was negative and the PCR for Chlamydia trachomatis was positive. Subsequently, the lab reported a positive bacteriological culture for sero-group C N. meningitidis, sensitive to ceftriaxone and a negative PCR for N. gonorrhoeae. N. meningitidis is the main cause of bacterial meningitis, but genomic studies have suggested that alleles of nitrate reductase, factor-H biding protein and capsule are associated with N. meningitidis isolation in genitourinary infections. Transmission from the oropharynx to the urethra through orogenital contact in unprotected oral sex has been widely proven. N. meningitidis prevalence as the cause of the urethritis is low, and the asymptomatic carriers in the urethra are extremely rare. PCR is a method for the N. gonorrhoeae and C.trachomatis diagnoses, but it does not detect N. meningitidis. The gonorrhoea diagnosis is based on an increased number of polymorphonuclear cells, with intracellular gram-negative diplococci in Gram' stain of urethral discharge. In our case, the gram-negative diplococcus seen in the stain was a meningococcus. Urethritis due to N. meningitidis is indistinguishable from the secondary to N. gonorrhoeae, mimicking it even microscopically, only the epidemiology varies. The conventional bacteriological culture continues to be essential for a correct diagnosis.

Potential therapeutic targets for combating Mycoplasma genitalium

Mycoplasma genitalium (M. genitalium) has emerged as a sexually transmitted infection (STI) all over the world in the last three decades. It has been identified as a cause of male urethritis, and there is now evidence that it also causes cervicitis and pelvic inflammatory disease in women. However, the precise role of M. genitalium in diseases such as pelvic inflammatory disease, and infertility is unknown, and more research is required. It is a slow-growing organism, and with the advent of the nucleic acid amplification test (NAAT), more studies are being conducted and knowledge about the pathogenicity of this organism is being elucidated. The accumulation of data has improved our understanding of the pathogen and its role in disease transmission. Despite the widespread use of single-dose azithromycin in the sexual health field, M. genitalium is known to rapidly develop antibiotic resistance. As a result, the media frequently refer to this pathogen as the "new STI superbug." Despite their rarity, antibiotics available today have serious side effects. As the cure rates for first-line antimicrobials have decreased, it is now a challenge to determine the effective antimicrobial therapy. In this review, we summarise recent M. genitalium research and investigate potential therapeutic targets for combating this pathogen.

Investigating the microbial pathogens of sexually transmitted infections among heterosexual Vietnamese men with symptomatic urethritis

OBJECTIVE

To explore the microbial etiology of urethritis in Vietnamese men and the association with patients' characteristics, especially their sexual behaviors.

METHODS

This study was conducted on 349 men who presented with symptomatic urethritis and evidence of STIs (determined by multiplex PCR tests) at the Department of Andrology and Sexual Medicine-Hanoi Medical University Hospital. All information regarding medical history, sexual activities, and symptoms of urethritis was documented.

RESULTS

C. trachomatis and N. gonorrhoea remained the two most common causative pathogens, followed by an unexpectedly high prevalence of Mycoplasma and Ureaplasma species. Coinfection was significant with a rate of 40.7%. Men who had sex with female sex workers (FSWs) were more likely to be positive with N. gonorrhoea but less likely to be positive with C. trachomatis and M. genitalium than those having sex with only one romantic partner.

CONCLUSIONS

Our findings suggested the important role of other microorganisms, especially M. genitalium, in the etiology of urethritis in men besides the previously well-known causes of STIs. Since the coinfection rate is quite high, targeted treatment with clear microbial evidence should be considered rather than empiric antimicrobial therapy.

Corynebacterium glucuronolyticum in men with and without urethritis syndrome: An underrecognized pathogen or a bona fide commensal?

BACKGROUND

By analysing the largest collection of Corynebacterium glucuronolyticum (C. glucuronolyticum) isolates from a single centre thus far, we aimed to appraise a potential causal link between an infrequently isolated species and the urethritis syndrome in men.

METHODS

A total of 1055 Caucasian male individuals with or without urethritis syndrome were included in this single-centre case-control study. Group-wise comparisons were pursued by analysing sociodemographic, behavioural and microbiological specificities between the two groups. C. glucuronolyticum isolates from urethral specimens were identified using the analytical profile index biotyping system (API Coryne) and additionally confirmed by MALDI-TOF mass-spectrometry, with subsequent determination of their antimicrobial sensitivity profiles. Statistical significance was set at p < 0.05 (two-tailed).

RESULTS

C. glucuronolyticum was isolated in 5.08% of study participants with urethritis syndrome and 3.60% of those without it (p = 0.303). In the urethritis group, the species was more frequently found as a sole isolate (p = 0.041) and after prior infection with Chlamydia trachomatis (p = 0.025). The most frequent presentation of urethritis included a clear discharge in small or moderate amounts, without any pathognomonic findings. The resistance rates were 62.22% for clindamycin, 42.22% for tetracycline and 26.67% for ciprofloxacin.

CONCLUSIONS

Our study provides major insights on the relevance of urethral C. glucuronolyticum in non-gonococcal urethritis, with significant implications for further aetiological research and management approaches.

Mycoplasma genitalium screening in a specialized French unit: A retrospective study

OBJECTIVE

Mycoplasma genitalium (MG) infection accounts for 10-35% of non-gonococcal non-chlamydial (NGNC) urethritis. However, given that most people infected with MG do not develop symptoms and that antimicrobial resistance is increasing worldwide, there is no evidence of any benefits of screening asymptomatic individuals. We conducted this study to describe MG screening practices and outcomes at a French Sexually Transmitted Infections (STI) center in which MG testing was performed selectively and multiplex assays were not carried out [i.e., simultaneous screening for Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and MG].

METHODS

A retrospective, observational, single-center study was conducted at the STI unit of Saint-Louis Hospital in Paris. The records of all patients undergoing MG testing from January 1st, 2017, to December 31st, 2018, were reviewed. The primary aim of the study was to describe and evaluate the proportion of MG-positive (MG+) patients among those tested. Secondary objectives were determination of the prevalence of MG+ status among symptomatic patients, risk factors associated with MG infection, and therapeutic modalities and efficacy.

RESULTS

Two hundred and forty-nine patients underwent MG testing, 28 (11%) of whom were positive (MG+). The prevalence of MG+ status among symptomatic NGNC patients was 12%. HIV-positive (HIV+) status was significantly associated with MG+ status in univariate and multivariate analyses (Odds Ratio=7.3, 95% Confidence Interval 1.3-41.7; P=0.02). Twenty-three patients (85%) received antibiotics. Eighteen (67%) received azithromycin for 5 days, but 7 had clinical resistance. No quinolone resistance was reported.

CONCLUSION

Despite unavailability of multiplex testing at our facility, which led to targeted-only screening for MG, its relatively high local prevalence is in keeping with what is generally observed at similar facilities across the world, where use of multiplex tests enables systematic screening for MG alongside NG and CT. This reinforces the current recommendations in Europe, France and the US against systematic MG testing or treatment in asymptomatic patients.

Sexually Transmitted Infections During the First Wave of the COVID-19 Pandemic in Spain

OBJECTIVE

To describe changes in sexually transmitted infection (STI) diagnoses during the first wave of the COVID-19 pandemic in Spain.

MATERIAL AND METHODS

We collected demographic, chronological, and clinical data for all patients seen for a possible STI at Hospital La Paz, Centro Sanitario Sandaval, and Centro de Diagnóstico Médico in Madrid and Hospital Costa del Sol in Malaga between March 14, 2020 and June 30, 2020.

RESULTS

We identified 674 STI diagnoses. The median age of the patients was 33 years. Most cases were observed among people aged 30 to 40 years and among men who have sex with men. The most common diagnoses were proctitis (36.5%), syphilis (16%), nongonococcal (13.3%) and gonococcal (11.3%) urethritis, genital herpes (8.8%), vulvovaginitis/cervicitis (8.3%), and genital warts (4.2%). A microbiologically confirmed diagnosis was on record for 77% of cases. The main microorganisms identified wereChlamydia trachomatis (35.7%), Neisseria gonorrhoeae (31.4%), and Treponema pallidum (17.2%). The number of STI diagnoses increased after the easing of lockdown restrictions, which resulted in greater freedom of movement and more consultations. On comparing the 2019 and 2020 STI registries from Centro Sanitario Sandoval and Hospital La Paz for the period March to June, we observed reductions (of up to 81%) in all STI diagnoses.

CONCLUSIONS

Physical distancing and movement restrictions appear to have resulted in a reduction in the incidence of STIs, although these measures did not completely eliminate sexual risk behaviors.

Fulminant corporal infection induced by Fournier gangrene: A case report with unusual presentation

Fournier gangrene is a life-threatening surgical emergency caused by multiple infectious organism usually affecting the subcutaneous perineal, genital or perianal region with high incidence in immunocompromised patients.

In very rare situations such our case when it involves the Deep perineal fascia and invading into the corporal body, the necrotizing tissue spread and control becomes more challenging and lead into devastating events with high mortality rate.

Staged timely debridement with highly daily examination to rule out necrosis spread is highly recommended.

Infection with the US Neisseria meningitidis urethritis clade does not lower future risk of urethral gonorrhea

BACKGROUND

Cross-protective immunity between Neisseria meninigitidis (Nm) and Neisseria gonorrhoeae (Ng) may inform gonococcal vaccine development. Meningococcal serogroup B (MenB) outer membrane vesicle (OMV) vaccines confer modest protection against gonorrhea. However, whether urethral Nm infection protects against gonorrhea is unknown. We examined gonorrhea risk among men with US Nm urethritis clade (US_NmUC) infections.

METHODS

We conducted a retrospective cohort study of men with urethral US_NmUC (N=128) between January 2015 and April 2018. Using diagnosis date as the baseline visit, we examined Ng status at return visits to compute urethral Ng risk. We compared these data to three referent populations: men with urethral Ng (N=253), urethral chlamydia (Ct) (N=251), and no urethral Ng or Ct (N=255). We conducted sensitivity analyses to assess varied approaches to censoring, missing data, and anatomical site of infection. We also compared sequences of protein antigens in the OMV-based MenB-4C vaccine, US_NmUC, and Ng.

RESULTS

Participants were primarily Black (65%) and heterosexual (82%). Over follow-up, 91 men acquired urethral Ng. Men with urethral US_NmUC had similar Ng risk to men with prior urethral Ng (adjusted hazard ratio (AHR): 1∙27, 95% CI: 0∙65-2∙48). Men with urethral US_NmUC had insignificantly increased Ng risk compared to men with urethral Ct (AHR: 1∙51, 95% CI: 0∙79-2∙88), and significantly increased Ng risk compared to men without urethral Ng or Ct (AHR: 3∙55, 95% CI: 1∙27-9∙91). Most of the protein antigens analyzed shared high sequence similarity.

CONCLUSIONS

Urethral US_NmUC infection did not protect against gonorrhea despite substantial sequence similarities in shared protein antigens.

[Sexually Transmitted Infections During the First Wave of the COVID-19 Pandemic in Spain]

Objetivo

Describir los cambios en el comportamiento de las ITS durante la situación de alerta sanitaria por la pandemia SARS-CoV-2.

Material y métodos

Se recogieron datos demográficos, cronológicos y clínicos de todos los pacientes que solicitaron atención médica por ITS en los hospitales La Paz y Costa del Sol, y en los Centros Sandoval y de Diagnóstico Médico, entre el 14/03/2020 y el 30/06/2020.

Resultados

Documentamos 674 casos de ITS. La mediana de edad fue de 33 años. El mayor porcentaje de casos se dio en el rango de 30-40 años y en hombres que tenían sexo con hombres. Los diagnósticos más frecuentes fueron: proctitis (36,5%), sífilis (16%), uretritis no gonocócica (13,3%) y gonocócica (11,3%), herpes genital (8,8%), vulvovaginitis/cervicitis (8,3%) y condilomas (4,2%). En el 77% de los casos hubo confirmación microbiológica, siendo los microorganismos más frecuentes Chlamydia trachomatis (35,7%), Neisseria gonorrhoeae (31,4%) y Treponema pallidum (17,2%). Se constató un incremento del número de casos de ITS tras el desconfinamiento, explicable por las mayores libertades y el aumento de consultas. Comparando los registros de ITS del Centro Sandoval y del Hospital La Paz en los cuatrimestres de marzo a junio de 2019 frente a 2020, se observó una disminución en 2020 de todos los diagnósticos, de hasta el 81% menos que en 2019.

Conclusiones

Las medidas de distanciamiento y limitación de movilidad aparentemente generaron una disminución de la incidencia de ITS, pero sin llegar a una inhibición completa de las conductas sexuales de riesgo.

Main etiological agents identified in 170 men with urethritis attended at the Fundação Alfredo da Matta, Manaus, Amazonas, Brazil

Background

Sexually transmitted infections (STI) are a global public health problem. Urethritis are among the most common STIs, and can cause several complications and facilitate the transmission of the HIV virus.

Objectives

To investigate the main etiologic agents of urethritis in 170 men treated at Fundação Alfredo da Matta.

Methods

To identify the agents, urethral exudate and urine were collected. Gram and culture tests were performed in Thayer-Martin medium for Neisseria gonorrhoeae and polymerase chain reaction for Neisseria gonorrhoeae, Chlamydia trachomatis, Trichomonas vaginalis, Ureaplasma urealyticum, Ureaplasma parvum, Mycoplasma hominis, Mycoplasma genitalium, and herpes simplex types 1 and 2.

Results

N. gonorrhoeae were identified in 102 (60.0%) patients, C. trachomatis in 50 (29.4%), U. urealyticum in 29 (17.0%), M. genitalium in 11 (6.5 %), U. parvum in ten (5.9%), and M. hominis in seven (4.1%). Herpes simplex type 2 was diagnosed in 24 (21.6%) of the 111 patients who underwent PCR for this pathogen. In 69 cases there was co-infection; the most frequent were: N. gonorrhoeae and C. trachomatis in 21 (14.7%) patients; N. gonorrhoeae and C. trachomatis in 21 (12.4%) patients; N. gonorrhoeae and herpes simplex type 2 in 11 (6.5%), and N. gonorrhoeae and U. urealyticum in nine (5.3%).

Study limitations

Not relevant.

Conclusion

N. gonorrhoeae, C. trachomatis, U. urealyticum, and herpes simplex type 2 were the pathogens most frequently identified in the present study. The main coinfection found was N. gonorrhoeae and C. trachomatis. T. vaginalis and herpes simplex type 1 were not identified in any of the patients.

Detection of the United States Neisseria meningitidis urethritis clade in the United Kingdom, August and December 2019 - emergence of multiple antibiotic resistance calls for vigilance

Since 2015 in the United States (US), the US Neisseria meningitidis urethritis clade (US_NmUC) has caused a large multistate outbreak of urethritis among heterosexual males. Its ‘parent’ strain caused numerous outbreaks of invasive meningococcal disease among men who have sex with men in Europe and North America. We highlight the arrival and dissemination of US_NmUC in the United Kingdom and the emergence of multiple antibiotic resistance. Surveillance systems should be developed that include anogenital meningococci.

Haemophilus spp., an emerging multidrug-resistant sexually transmitted pathogen

OBJECTIVES

To describe the characteristics of patients with a positive urethral sample for Haemophilus spp.

MATERIAL AND METHODS

We performed a retrospective study from January 2018 to July 2019 at the Bordeaux university hospital (France) of all urethral samples positive for Haemophilus spp.

RESULTS

Haemophilus spp. was isolated in 10 urethral samples from nine patients. The mean age was 33.8 years. Most patients reported having unprotected sex. Haemophilus parainfluenzae was isolated in nine samples, and Haemophilus influenzae in one sample. Antibiotic susceptibility tests were performed in five samples; Haemophilus spp. was always resistant to amoxicillin and tetracycline. One patient had persistent symptoms after treatment for a multidrug-resistant Haemophilus parainfluenzae strain.

CONCLUSION

Haemophilus spp. is a rare pathogen of urethritis. Its responsibility should be considered in case of persistent symptoms. The emergence of multidrug-resistant Haemophilus spp. is becoming problematic.

Haemophilus urethritis in males: A series of 30 cases

INTRODUCTION AND OBJECTIVES

Pathogens such as Haemophilus spp. have been associated with non-gonococcal urethritis, but their role is unproven. To describe the clinical characteristics and therapeutic outcomes in male patients diagnosed with Haemophilus spp. urethritis.

METHODS

We carried out a retrospective study of all patients who presented to our hospital (in either the emergency department or the outpatient clinic) between July 2016 and April 2018 in whom Haemophilus spp. was isolated in the urethral samples. We enrolled 30 men with Haemophilus spp.-positive urethritis, including coinfections with Neisseria gonorrhoeae and Chlamydia trachomatis. Clinical, laboratory, demographic, and behavioral data were obtained by reviewing medical histories.

RESULTS

The mean age of the patients was 36.6 years (range 21-87). Seventeen patients (63%) reported being exclusively heterosexual. Three patients (10%) were HIV infected, all of them with an undetectable viral load. The most common clinical presentation was mucopurulent urethral discharge, in 13 patients (43%). The antibiotic treatment achieved a complete clinical resolution in 73%.

CONCLUSIONS

Haemophilus urethritis affected men regardless of their sexual orientation or HIV status. Unprotected oral sex may play a role in its transmission. The limitations of the study preclude verification of the pathogenic role of Haemophilus spp. in acute urethritis, but clinical response after antibiotic treatment suggests that Haemophilus spp. can play such a role.

Childhood and adolescent idiopathic urethritis: what does the current literature say?

INTRODUCTION

Idiopathic urethritis (IU) is a known entity in the childhood and adolescent age groups and is described as blood spotting of the underwear in these populations. Typically, IU presents clinically as terminal void haematuria or blood spotting, accompanied with dysuria, occasional suprapubic pain and rarely constitutional symptoms. Sometimes IU may progress to formation of urethral strictures. It carries a high morbidity because of its chronicity and recurrent course, which often persists to puberty. In spite of no single aetiology being confirmed, several treatment approaches have shown some efficacy. Although no consensus has yet been established, the consideration of previous authors' experience and expertise may contribute to the development of a possible unified algorithm.

AIM

This article considers IU, collecting pertinent data and case series from the literature. The authors attempt to describe all presumptive aetiologies, endoscopic findings with established grading classifications and finally the various treatment modalities proposed. In addition, highlights from the senior's author experience regarding this entity including endoscopic, radiographic and histological images are mentioned.

METHODS

Retrospective review and analysis of all relevant articles present on PubMed, SCOPUS and Cochrane Library from the time of inception to the date of first submission.

RESULTS

A total of 19 series concerning IU have been reported since year 1971 to present time (Table 1). Many aetiologies have been postulated, but some have been refuted, including infectious pathogens. Children with dysfunctional voiding and meatal stenosis are more prone to exhibit IU. A variation in the urethral milieu during the prepubertal period, secondary to systematic hormonal alteration, may lead to squamous cell metaplasia resulting in IU and possible urethral strictures. Grading classifications for IU are described. Up to 20% of IU may develop urethral strictures. Various treatment approaches are discussed.

CONCLUSION

A summary of current understanding of the pathogenesis and spectrum of IU has been achieved. Successful treatment can be achieved with steroids and dysfunctional voiding protocols. It may be possible to develop a consensus unified management algorithm.

Is Non-Chlamydial Non-Gonococcal Urethritis Associated with Significant Clinical Complications in Men? A Systematic Review

Background

It is estimated that between 50 and 89% of non-gonococcal urethritis is not caused by Chlamydia trachomatis. Associations between non-chlamydial non-gonococcal urethritis (NCNGU) with balanoposthitis, epididymo-orchitis and reactive arthritis have been suggested, but evidence to support these often-theoretical relationships is sparse and further investigation is called for. Concerns over increasing antimicrobial resistance has rendered the need for clarity over this question ever more pressing in recent years. A review of the current evidence on the complications of NCNGU in men is therefore urgently warranted.

Objective

This systematic review summarizes and evaluates the available evidence that NCNGU, whether symptomatic or asymptomatic, causes the significant complications that are already well-recognized to be associated with non-gonococcal urethritis. These significant complications are epididymo-orchitis, balanoposthitis, and sexually-acquired reactive arthritis (Reiter's syndrome) including arthritis or conjunctivitis.

Summary

We conducted a systematic review and qualitative synthesis using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis framework. Five databases (PubMed, EMBASE, Cumulative Index to Nursing and Allied Health Literature, PsycINFO, and British Nursing Index) were searched. We included studies that measured clinical outcome after diagnosis of NCNGU in men. Bias was assessed using variations of the Newcastle-Ottawa scale. Data were extracted and entered into a pre-written data abstraction proforma. Seven peer-review studies were included. This included 2 retrospective cohort studies, 1 case series, 2 case reports and 2 cross-sectional studies. The studies described and analyzed 3 types of complication: balanitis, posthitis and/or meatitis; reactive arthritis and/or conjunctivitis; and epididymitis. All studies reported one or more complications.

Key Messages

This review identifies an important avenue for future research: while the available evidence suggests that NCNGU has the potential to cause significant complications in men, with the strongest evidence existing for balanitis, posthitis and/or meatitis, the nature and significance of these relationships is far from clear. The findings of this review suggest that prospective, adequately powered research into whether there is a causal link between NCNGU and significant clinical complications in men would be highly worthwhile. The findings of this review raise important questions about the utility of the term NCNGU in research and clinical practice.

Isotretinoin induced urethritis: A case report & review of the literature

We report a case of urethritis in a 17-year-old non-sexually active male that developed after starting isotretinoin treatment for his acne. Clinicians must be vigilant about this adverse effect and elicit a thorough medication history prior to administering antibiotics in patients taking isotretinoin treatment for acne.

Men at risk of gonococcal urethritis: a case-control study in a Darwin sexual health clinic

BACKGROUND

Male urethritis is primary sexually transmitted. Northern Territory (NT) has the highest rates of gonococcal infection in Australia and local guidelines recommend empiric treatment with azithromycin and ceftriaxone for all men presenting with urethritis. As gonococcal drug resistance is a growing concern, this study aims to improve empiric use of ceftriaxone through examining local patterns of male urethritis, comparing cases of gonococcal urethritis (GU) to controls with non-gonococcal urethritis (NGU).

METHODS

A retrospective study was undertaken of all men with symptomatic urethritis presenting to Darwin sexual health clinic from July 2015 to July 2016 and aetiology of urethritis in this population was described. Demographic, risk profile, and clinical features of GU cases were compared to NGU controls.

RESULTS

Among n = 145 men, the most common organisms identified were Chlamydia trachomatis (23.4%, SE 3.5%) and Neisseria gonorrhoeae (17.2%, SE 3.1%). The main predictors of GU were any abnormalities on genital examination (aOR 10.4, 95% CI 2.1 to 50.8) and a history of urethral discharge (aOR 5.7, 95% CI 1.4 to 22.6). Aboriginal patients (aOR 3.0, 95% CI 0.9 to 9.6) and those over 30 years of age (aOR 1.4, 95% CI 0.3 to 7.0) were more likely to have GU in the unadjusted analysis, but not in the adjusted model.

CONCLUSION

This is the first study looking at patterns of male urethritis in urban NT and the results support a move towards adopting national guidelines to use ceftriaxone for empiric management of syndromic urethritis only in high-risk patients. In addition to traditional demographic risk factors, clinical features remain an important component of risk stratification.

Estimate of male urethritis incidences in France between 2007 and 2017 with a specific focus on Neisseria gonorrhoeae, Chlamydia trachomatis, and Trichomonas vaginalis infections

Background

In a context of increasing use of Nucleic Acid Amplification Test, diagnoses of Neisseria gonorrhoeae and Chlamydia trachomatis infections among men increased in Europe and USA since 2007. We aimed to describe trends in the incidence of male urethritis in France between 2007 and 2017.

Methods

We analysed male urethritis clinical cases reported by the French GPs’ Sentinelles network.

Results

GPs reported 1944 cases of male urethritis during the study period. The estimated annual incidence rates in men aged 15 years and older remained stable between 226 cases per 100,000 seen in 2007 and 196 in 2017 (P value = 0.9). A third-generation cephalosporin with macrolide or tetracycline was prescribed in 17.5% of cases in 2009 (27/154) and 32.4% in 2017 (47/145) (P value = 0.0327).

Conclusions

The incidence rates for adult male urethritis diagnosed in primary care have remained stable since 2007 in France in contrast with the increasing trend of Neisseria gonorrhoeae and Chlamydia trachomatis infections based on microbiological surveillance. Using stable clinical definition for male urethritis seems essential to follow correctly epidemiological dynamic.

Specific characteristics of urethral strictures in a developing country (Brazil)

PURPOSE

Evaluate the main etiologies and clinical characteristics of male urethral stricture disease (USD) in Brazil.

METHODS

This multicentric study was performed using retrospective data collected from six Brazilian referral centers of urethral reconstruction. The database comprised data from 899 patients with USD who had undergone surgical treatment from 2008 to 2018. Age, stricture site and primary stricture etiology were identified for each patient.

RESULTS

The mean age was 52.13 ± 16.9 years. The most common etiology was iatrogenic (43.4%), followed by idiopathic (21.7%), trauma (21.5%) and inflammatory (13.7%). Of the iatrogenic causes, 59% were secondary to urethral instrumentation (60% by urethral catheterization and 40% by transurethral procedures), 24.8% by other procedures (prostatectomy, radiotherapy, postectomy) and 16.2% by failed hypospadia repairs. Pelvic fracture urethral distraction injuries were responsible for most of the trauma-related strictures (62.7%). When stratified by age, the most common stricture etiology was trauma in the 0-39 years old group (42.8%), idiopathic in the 40-59 years old group (32.4%) and iatrogenic in patients over 60 years old (68%). In regard to the stricture site, 80% presented with an anterior urethral stricture and 20% with a posterior stenosis. In the anterior stenosis group, the most common stricture site was bulbar (39.5%).

CONCLUSION

In Brazil, as in many developed countries, the most common cause of urethral stricture diseases is iatrogenic, especially urethral catheterization. These findings emphasize the need of a careful urethral manipulation and a better training of healthcare professionals. Trauma is still responsible for a great proportion of strictures and inflammatory etiologies are now less frequently observed.

Management of Urethritis: Is It Still the Time for Empirical Antibiotic Treatments?

CONTEXT

Urethritis prevalence in Europe changed in the last years due to both the increase of migratory streams from North Africa and the more frequent exposition of males to relevant risk factors. Owing to these reasons, urethritis treatment should be optimized by accurate microbiological investigations to avoid the risk of persistence, recurrence, or reinfection.

OBJECTIVE

The aim of this systematic review is to optimize the treatments for urethritis and investigate the applicability of nucleic acid amplification test (NAAT) as the primary microbiological investigation.

EVIDENCE ACQUISITION

A literature search in Medline, Cochrane, and Google Scholar databases was conducted up to June 2018. Subject headings were selected as follows: Urethritis OR gonococcal urethritis OR non-gonococcal urethritis AND Antibiotics OR Recurrence. A total of 528 abstracts were identified and selected. Finally, 12 full-text articles were selected for a qualitative synthesis. The Preferred Reported Items for Systematic Reviews and Meta-Analyses statement was used to perform an accurate research checklist and report.

EVIDENCE SYNTHESIS

Empirical treatments are no more recommended, although a broad spectrum of antibiotic therapy may be initiated while awaiting the results from pathogens' microbiological characterization. First-line treatment for gonococcal urethritis consists of a single dose of ceftriaxone/azithromycin combined therapy. Specific therapies should be initiated for nongonococcal urethritis according to each single pathogen involved in the infection process. Owing to this reason, NAAT is mandatory in the clinical approach to the disease, although the Gram stain of urethral discharge or smear remains applicable for some less frequent nongonococcal urethritis. Moreover, the urethritis "modern view" also includes noninfectious etiologies that occurred after traumas or injection of irritating compounds. Sexual abstinence of at least 7 d should be observed from the start of treatment to avoid reinfection, while sexual partners should evenly be treated.

CONCLUSIONS

The treatment of urethritis implies accurate determination of pathogens involved in the infection process by NAAT with subsequent appropriate antibiotic therapy, thus avoiding the risk of antibiotic resistance and overuse of antibiotics indicated for empirical treatments. The population exposed to relevant risk factors should be adequately informed about the increased risk of developing infections and motivated toward the intensive use of condoms during sexual intercourses.

PATIENT SUMMARY

Urethritis is a sexually transmitted disease generally characterized by urethral discharge or other symptoms such as itching, tingling, and apparent difficulties in having a regular urinary flow. Microbiological investigations are mandatory to obtain satisfactory results from the treatment. Multiple antibiotic treatments are often necessary due to the high risk of multiple pathogens responsible for the disease. Similarly, sexual partners should be investigated and treated in the same way. Several risk factors such as immunodeficiency, multiple sexual partners, homo- and bisexuality, and alcohol abuse may be related to the disease. In these cases, the use of condom is strongly recommended.

A microbial game of whack-a-mole: clinical case series of the urethral uncloaking phenomenon caused by Corynebacterium glucuronolyticum in men treated for Chlamydia trachomatis urethritis

Corynebacterium glucuronolyticum is a rare and neglected, but increasingly recognized bacterial agent of infectious urethritis and other genitourinary syndromes in men. This is the first description of its proclivity to resurface as a cause of sustained urethritis in male patients previously treated for Chlamydia trachomatis, which represents a phenomenon that has to be differentiated from a simple post-treatment overgrowth of a colonizing agent.

Isotretinoin-induced urethritis versus non-gonococcal urethritis in a man who has sex with men: an open debate

This is the case of a young man presenting with urethritis despite a negative infectious work-up. Careful history taking elucidated a strong correlation between symptom onset and a recent dose escalation of isotretinoin for treatment of his refractory cystic acne. The urethral symptoms quickly resolved with dose reduction, suggesting urethritis as a rare adverse reaction of isotretinoin.

GyrA and/or ParC alterations of Haemophilus influenzae strains isolated from the urethra of men with acute urethritis

Of 73 clinical strains of Haemophilus influenzae isolated from the urethra of men with urogenital infections, we enrolled 6 strains (8.2%) with levofloxacin (LVFX) minimum inhibitory concentrations (MICs) of ≥0.03 μg/ml in this study. All the strains were isolated from non-gonococcal urethritis (NGU). We amplified the quinolone resistance-determining region of the gyrA gene and the analogous region of the parC gene from bacterial DNAs by PCR and sequenced the PCR products. Two strains with a LVFX MIC of 0.03 μg/ml had an amino acid change of Asp88 to Gly in GyrA. One with a LVFX MIC of 0.06 μg/ml had a change of Asp88 to Tyr in GyrA. Two with respective LVFX MICs of 0.12 and 0.25 μg/ml had a change of Ser84 to Leu in GyrA. One with a LVFX MIC of 1 μg/ml had changes of Ser84 to Leu in GyrA and of Ser84 to Ile in ParC. Multilocus sequence typing showed two strains with a change of Asp88 to Gly in GyrA had the same sequence type, but the others had sequence types different from each other. Single amino acid changes in GyrA alone or single changes in both GyrA and ParC could contribute to decreased susceptibility to fluoroquinolones in H. influenzae isolates from NGU. Most of the isolates with GyrA and/or ParC alterations would be multiclonal. The prevalence of such isolates would be relatively low, and they would still be susceptible to fluoroquinolones commonly prescribed for treatment of NGU.

Asymptomatic and symptomatic urethral gonorrhoea in men who have sex with men attending a sexual health service

OBJECTIVES

Guidelines regarding whether men who have sex with men (MSM) without symptoms of urethritis should be screened for urethral gonorrhoea differ between countries. We examined the rate of asymptomatic urethral gonorrhoea in MSM using sensitive nucleic acid amplification testing.

METHODS

This study was conducted on consecutive MSM attending the Melbourne Sexual Health Centre between July 2015 and May 2016 for sexually transmitted infections screening. Gonorrhoea testing with the Aptima Combo 2 (AC2) assay was performed on all urine specimens obtained from MSM, whether symptoms of urethritis were present or not. Men were classified as having: typical discharge if they reported symptoms suggesting purulent discharge; other symptoms if they reported other symptoms of urethritis; and no symptoms if they reported no urethral symptoms.

RESULTS

During the study period, there were 7941 clinic visits by 5947 individual MSM with 7090 urine specimens obtained from 5497 individual MSM tested with the AC2 assay. Urethral gonorrhoea was detected in 242 urine specimens from 228 individual MSM. The majority (189/242, 78%, 95% CI 73-83) reported typical discharge, 27/242 (11%, 95% CI 8-16) reported other urethral symptoms, and 26/242 (11%, 95% CI 7-15) reported no symptoms on the day of presentation and testing. Among men with urethral gonorrhoea, the proportions with concurrent pharyngeal or rectal gonorrhoea were 32% (134/210) and 64% (74/235), respectively. The mean interval between last reported sexual contact and onset of typical urethral discharge, where present, was 3.9 days.

CONCLUSION

The findings from our study lend support to guidelines that recommend screening asymptomatic MSM for urethral gonorrhoea.

[Antibiotic stewardship (ABS). Definition, contents, necessity and practice on examples of current clinical-urological controversies]

BACKGROUND

Infectious diseases caused by multi-resistant pathogens are increasing worldwide and are posing a challenge to German urology as well. Furthermore, there is a limited perspective of new antibiotic developments. One way out of this dilemma is a differentiated handling and use of antibiotics (antibiotic stewardship, ABS).

AIM

The aim of this review is to identify key issues in modern urological antibiotic therapy, which can be considered as exemplary for the whole topic of ABS. This includes a review of the current data of the individual topics, including thought-provoking impulse for future clinical application and research.

MATERIAL AND METHODS

The research group "infectious diseases" of GeSRU Academics identified the following central topics: excessive use of fluoroquinolones, diagnosis and treatment of urethritis and perioperative antibiotic prophylaxis. Subsequently, we performed a literature research in MEDLINE to uncover controversies and open questions of the individual topics within the meaning of ABS.

RESULTS

The analysis of modern antibiotic therapy in urology shows numerous open questions in all quality dimensions of ABS: structural quality (e.g. through improved training of medical staff in the differentiated use of antibiotics), process quality (e.g. by improved adherence to existing infectiological guidelines, here in particular the perioperative prophylaxis and therapy of urethritis) and outcome (e.g. by detection of resistance rates and infection rates).

DISCUSSION

The overarching and common goal is to avoid a post-antibiotic era. ABS programmes and a 10-point plan of the federal government are considered positive political developments in this area but do not release the individual urologist from a personal responsibility as part of his daily routine. A critical analysis of the topic "antibiotic treatment" is essential.

An Unusual Case of a Metallic Foreign Body per Urethra

Background

Foreign body in the lower urinary tract has a low incidence. Here we discuss a case of a safety pin within the bulbar urethra inserted by a young boy for sexual gratification, which was successfully removed under cysto-urethroscopic guidance.

Case Report

Herein we present a case of a 14-year-old boy who presented with complaints of perineal pain and dysuria. On evaluation in detail and from clinical history, we came to know that he had inserted a safety pin within the urethra. Urine analysis revealed microscopic haematuria and few pus cells. X-ray of the pelvis and computerised tomography helped in confirming the presence of the safety pin within the urethra.

Conclusions

The method of extraction of a foreign body per urethra depends on the size and shape of the foreign body. Cysto-urethroscopic removal is successful depending on the physical characteristics of the foreign body. It has the advantage of minimising urothelial trauma and also helps in assessing any previous mucosal injury or thickening. Psychological evaluation and counselling may help to prevent further such episodes.

Comparing between results and complications of doing voiding cystourethrogram in the first week following urinary tract infection and in 2-6 weeks after urinary tract infection in children referring to a teaching hospital

Introduction: Urinary tract infection is the most common genitourinary disease in children so about 40% of the children with urinary tract infection suffering from reflux that caused some consequences such as pyelonephritis and kidney parenchymal injury.

Objectives: This research was conducted to compare the timing of voiding cystourethrogram (VCUG) in children with urinary tract infection in first week and after the first week of urinary tract infection.

Patients and Methods: This research is a case-control study that both case and control groups include 208 children from 1 month to 12 years old with the complain of urinary tract infection. In case group, the VCUG was performed at the first week of infection and in control group, the VCUG was performed after the first week of infection.

Results: complication such as dysuria was observed in two-thirds of children who VCUG was performed during first week after urinary tract infection. Parents stress in case group was more than the other (P=0.015). For overall, the incidence of reflux in case and control groups was 49.5% and 50%, respectively. The mean of reflux grading in right kidney in case group was lower than control group resulting in significant differences between two groups.

Conclusion: According to higher grade of stress in parents and complications due to VCUG at the first week of urinary tract infection, it is suggested that VCUG be conducted on selective patients in the hospital at the first week of urinary tract infection and during hospitalization.

Prevalence of Mycoplasma genitalium in men with urethritis and in high risk asymptomatic males in Tel Aviv: a prospective study

We sought to investigate the prevalence of Mycoplasma genitalium, Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis in men presenting to a sexually transmitted infection (STI) clinic, with special attention to M. genitalium, its occurrence in Israeli patients, coinfections, and risk factors. In a cross-sectional study, 259 men were successively enrolled in the Tel Aviv Levinsky Clinic for STIs between November 2008 and November 2010. There were 118 men with urethritis and 141 high-risk men without symptoms. M. genitalium, C. trachomatis, N. gonorrhoeae, and T. vaginalis were detected using nucleic acid amplification tests. Demographic characteristics and risk factors were documented. The overall prevalence of infection with M. genitalium, C. trachomatis, N. gonorrhoeae, and T. vaginalis, were 6.6%, 12.7%, 23.1%, and 0%, respectively. Prevalences in men with urethritis were 11.9%, 22%, and 49%, for M. genitalium, C. trachomatis, and N. gonorrhoeae, respectively. Prevalences in men without symptoms were 2.1%, 5.0%, and 1.4%, for M. genitalium, C. trachomatis, and N. gonorrhoeae, respectively. Co-infections were found only in symptomatic individuals, in whom 5.9% were infected concomitantly with C. trachomatis and N. gonorrhoeae, and 2.5% had dual infection with M. genitalium and N. gonorrhoeae. N. gonorrhoeae, C. trachomatis, and M. genitalium were significantly more prevalent in patients with urethritis. M. genitalium was significantly more prevalent in the heterosexual population than in homosexual males. To conclude, we have found that M. genitalium infection is associated with urethritis in Israeli men, and more so in the heterosexual population. Testing men for M. genitalium as a cause of non-gonococcal urethritis is warranted, particularly because of its poor response to doxycycline and possible failure of azithromycin.

Haemophilus parainfluenzae urethritis among homosexual men

Haemophilus parainfluenzae is a common inhabitant of the human upper respiratory tract of the normal oral microflora. We report three men who had been having unprotected sex with men (MSM) and subsequently acquired H. parainfluenzae urethritis, which was confirmed by 16S rRNA gene sequencing analysis. Two men were treated with ceftriaxone and doxycycline, and the third man was treated with clarithromycin. All three patients responded to treatment. This case series highlights the potential role of H. parainfluenzae as a sexually transmitted genitourinary pathogen.

Loop-mediated isothermal amplification (LAMP) for the rapid detection of Mycoplasma genitalium

Mycoplasma genitalium is a sexually transmissible, pathogenic bacterium and a significant cause of nongonococcal urethritis in both men and women. Due to the difficulty of the culture of M. genitalium from clinical samples, the laboratory diagnosis of M. genitalium infection is almost exclusively carried out using nucleic acid amplification tests. Loop-mediated isothermal amplification (LAMP) is a novel nucleic acid amplification technology, utilising a set of 4 primers specific to 6 distinct regions of the target DNA sequence, in order to amplify target DNA in a highly specific and rapid manner. A LAMP assay was designed to the pdhD gene of M. genitalium, and the limit of detection of the assay was determined as 10 fg of M. genitalium genomic DNA, equating to ~16 copies of the M. genitalium genome, which was equally sensitive as a gold standard 16S rRNA polymerase chain reaction assay.

Where do patients go for treatment of urethritis?

Background:

Urethritis is characterized by urethral inflammation, and it can result from both infectious and noninfectious conditions. Physicians and other health care providers play a critical role in preventing and treating urethritis.

Objectives:

The aim of this study was to describe and identify predictors of health care seeking behavior among men with urethritis.

Patients and Methods:

In total, 98 male patients aged between 16 to 52 years-of-age (mean 30.9 ± 8.0 years), who attended our clinic with symptoms of urethritis, were included in the study. We conducted face-to-face interviews with the patients using a 9-item survey questionnaire. Patients were divided into three groups according to their level of education as follows: group I (n = 44), elementary school; group II (n = 38), high school; and group III (n = 16), university.

Results:

Among the 98 patients evaluated, the source of treatment was physicians in 44 patients (44.9%), drugstores in 38 cases (38.77%), and friends in 16 patients (16.32%). There was a statistically significant difference found between the groups according to the source of treatment (P < 0.001). The most common factors associated with seeking care from other sources, rather than physicians, were economic reasons in 19 patients (35.18%), confidentiality concerns in 24 (44.4%), and ease of access in 11 patients (20.37%).

Conclusions:

A substantial proportion of patients with urethritis sought help from other sources, rather than physicians. The results of our study show that the patients with higher levels of education were more likely to seek help from health care services. It is important to promote the public’s knowledge through informative studies and educational materials in order to encourage patients to seek rapid and effective treatment from proper sources.

[Sexually transmitted diseases and other risks in the adult film industry]

The adult film industry nowadays represents a legal multi-billion dollar business. The main health risks of adult performers are well known. They mainly include the transmission of sexually transmitted diseases such as HIV, hepatitis, gonorrhoea, Chlamydia, herpes and papillomavirus. However, despite regular follow-up, the frequency of STD remains significant in this high-risk population since a large part of the industry continues to reject systematic use of condoms. Besides, performers are also exposed to other physical and mental health issues often not known to the public. This article provides a comprehensive review of what is known about STD and other risks among the community of performers in the adult film industry.

Trichomoniasis: the "neglected" sexually transmitted disease

Trichomonas vaginalis is the most prevalent nonviral sexually transmitted infection, affecting an estimated 3.7 million people in the United States. Although trichomoniasis is common, it has been considered a "neglected" sexually transmitted disease, due to limited knowledge of its sequelae and associated costs. This article reviews current epidemiology, pathophysiology, diagnostic methods, clinical management recommendations and special considerations, research on associated conditions and costs, prevention strategies, and controversies regarding trichomoniasis.

Mycoplasma genitalium: An emergent sexually transmitted disease?

This article summarizes the epidemiologic evidence linking Mycoplasma genitalium to sexually transmitted disease syndromes, including male urethritis, and female cervicitis, pelvic inflammatory disease, infertility, and adverse birth outcomes. It discusses the relationship of this bacterium to human immunodeficiency virus infection and reviews the available literature on the efficacy of standard antimicrobial therapies against M genitalium.

Trends and associations of Trichomonas vaginalis infection in men and women with genital discharge syndromes in Johannesburg, South Africa

OBJECTIVES

To better understand the epidemiology of Trichomonas vaginalis infection, we investigated the association between T vaginalis and demographic, clinical, microbiological and behavioural characteristics of patients presenting with genital discharges to a primary healthcare clinic in Johannesburg, South Africa.

METHODS

During six annual surveys (2007-2012), 1218 cases of male urethral discharge syndrome and 1232 cases of vaginal discharge syndrome were consecutively recruited. Diagnostic methods included nucleic acid amplification (Neisseria gonorrhoeae, Chlamydia trachomatis, T vaginalis and Mycoplasma genitalium), microscopy (bacterial vaginosis and Candida) and serology (Treponema pallidum, herpes simplex virus type 2 (HSV-2) and HIV). Logistic regression analyses and χ2 tests were used to identify predictors of T vaginalis infection.

RESULTS

The prevalence of T vaginalis decreased from 2007 to 2012 (men from 13.4% to 4.8%; women from 33.8 to 23.1%). Overall, 74 (6.1%) men and 291 (23.6%) women were T vaginalis positive, with the highest prevalence in those aged ≥40 years (men 13.6%; women 30.9%). T vaginalis infection occurred more often in pregnant women (adjusted OR (aOR) 2.67; 95% CI 1.29 to 5.54) and in women with serological evidence of T pallidum (aOR 1.63; 95% CI 1.08 to 2.45) or HSV-2 infections (aOR 1.75; 95% CI 1.16 to 2.64). T vaginalis infection occurred less often in men with coexistent gonorrhoea (aOR 0.35; 95% CI 0.21 to 0.57) and in women with either bacterial vaginosis (aOR 0.60; 95% CI 0.44 to 0.82) or Candida morphotypes (OR 0.61; 95% CI 0.43 to 0.86).

CONCLUSIONS

Although the prevalence of T vaginalis infection has decreased over time, it remains an important cause of genital discharge in South Africa, particularly in older patients and pregnant women.

Chlamydia and male lower urinary tract diseases

Of the chlamydia species that can cause infections in humans, C. trachomatis is responsible for lower urinary tract diseases in men and women. C. trachomatis infections are prevalent worldwide, but current research is focused on females, with the burden of disease and infertility sequelae considered to be a predominantly female problem. However, a role for this pathogen in the development of male urethritis, epididymitis, and orchitis is widely accepted. Also, it can cause complications such as chronic prostatitis and infertility. This review summarizes C. trachomatis infection in the male genitourinary tract, including urethritis, epididymitis, orchitis, and its complications, and addresses the microbiology, epidemiology, screening, clinical manifestations, diagnosis, and treatment.
