Juvenile Allergic Urethritis with Urethro-vasal Reflex Masquerading Cauda Equina Syndrome

We report a case of severe Juvenile Allergic Urethritis secondary to double concentrate orange squash of a famous brand in a 3-year-old boy who presented with urethral and perineal pain resulting in an abnormal gait and urinary symptoms suggestive of Cauda Equina Syndrome. Ultrasound of the Urinary Tract was normal as was the Magnetic Resonance Imaging (MRI) of the Spine. Withdrawal of the allergen produced complete recovery. Symptoms recurred on food challenge. There are several learning points and take-home messages in this case such as (1) Allergic Urethritis can have a dramatic presentation, mimicking serious conditions such as Cauda Equina Syndrome. (2) Food challenge provided the definitive diagnosis: this is the first report of double concentrate orange squash induced urethritis. (3) Complete avoidance has resulted in an enduring cure. (4) Appropriate timely referral by general Practitioner and cohesive and well-coordinated multidisciplinary team management at the University Teaching Hospital is required to successfully manage such rare and challenging case

Uretritis por haemophilus influenzae. primer reporte de caso en paraguay

Introducción: La uretritis es el síndrome más frecuente en el contexto de infección de transmisión sexual (ITS). Caso clínico: Paciente masculino de 26 años, bisexual, acude a una Clínica Comunitaria, por cuadro de un día de perdida espontánea y continua de secreción uretral, más disuria y adenomegalia izquierda. Niega fiebre y otros síntomas. Observación: última exposición sexual, oral insertiva, homosexual, casual y desprotegida, 7 días previos a sintomatología. Se solicitan testeos rápidos para ITS, orina simple, frotis y cultivo de exudado uretral. Se administra tratamiento empírico dual combinando y paciente evoluciona favorablemente. Informe de cultivo de exudado uretral positivo, aislándose Haemophilus influenzae. Discusión: La uretritis por H. influenzae es poco frecuente, presumiblemente adquirida por prácticas orogenitales desprotegidas. Es estadísticamente significativa en población HSH (hombres que tienen sexo con hombres). En Paraguay no se tienen datos sobre agentes etiológicos de uretritis infecciosa en varones, de allí la importancia del reporte.

Introduction: Urethritis is the most common syndrome in the context of sexually transmitted infection (STI). Clinical case: Patient of 26-year-old cis man, bisexual, attended a Community Clinic, complaining of one day of spontaneous and continuous loss of urethral secretion, plus dysuria and left adenomegaly. He denies fever and other symptoms. Observation: last sexual, oral insertive exposure, homosexual, casual and unprotected, 7 days prior to symptoms. Rapid tests for STIs, simple urine, smear and culture of urethral exudate are requested. Combined dual empirical treatment was administered and the patient progressed favorably. Positive urethral exudate culture report, isolating Haemophilus influenzae. Discussion: H. influenzae urethritis is rare, presumably acquired by unprotected oral practices. It is statistically significant in the MSM population (men who have sex with men). In Paraguay there is no data on etiological agents of infectious urethritis in men, hence the importance of the report.

Characterization of sexually transmitted infections, their pharmacological treatment, and recurrence in a Colombian population / Caracterización de las infecciones de transmisión sexual, su tratamiento farmacológico y la recurrencia en una población colombiana

Abstract | Introduction: Sexually transmitted infections are a public health problem worldwide. Their inadequate antimicrobial management has been associated with a higher risk of recurrence. Objective: To characterize the main sexually transmitted infections, the adherence to clinical practice guidelines, and the factors associated with recurrence in Colombia. Materials and methods: We conducted an observational study to identify the main sexually transmitted infections, the sociodemographic variables, and the pharmacological management in a patient cohort from a population database of 6.5 million people affiliated with the Colombian health system. We made a multivariate analysis to identify the variables associated with recurrence. Results: We detected 3,158 patients with a mean age of 41.8 ± 14.5 years, of whom 63.1% were men. We found 4.030 episodes of sexually transmitted infections, predominantly urethral syndrome (27.5%). Only 13.6% of patients with urethral syndrome, ulcerative syndrome, or genital warts were managed in compliance with clinical practice guidelines and 20.6% were dispensed condoms; 16.7% of patients had recurrences and being male (OR=1.32; 95%CI 1.08-1.63), <30 years old (OR=1.72; 95%CI 1.40-2.13), being treated in municipalities other than capital cities (OR=1.43; 95%CI 1.06-1.94), and having received inadequate treatment for the first episode (OR=1.93; 95%CI 1.52-2.39) were associated with recurrence. Conclusions: The majority of patients with sexually transmitted infections were not treated in compliance with clinical practice guidelines and those who did not have adequate management had a higher risk of recurrence.

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

Abstract 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.

Infecciones en varones por gardnerella vaginalis- revisión bibliográfica

Introducción: Gardnerella vaginalis ha sido aislada de orina, semen, descarga uretral, hisopos endouretrales, rectales y del prepucio, en algunos casos asociada a manifestaciones clínicas; se han descrito uretritis y balanopostitis con diversos porcentajes. Los hallazgos en frotis rectal, semen y prepucio deben interpretarse cuidadosamente para otorgarles significado clínico. Ha quedado demostrado que el hombre la adquiere de sus parejas sexuales y en su forma cohesiva. Objetivo: Explorar el papel patógeno de G. vaginalis como causa de infección en los hombres. Método: La estrategia de búsqueda se realizó en: PubMed/ Medline, Scopus Cochrane Library, SciELO Lilacs, Redalyc; Google Scholar con proveedores como: EB-SCO y tesauros MeSH y DeCS. Resultados: Las diferentes publicaciones indicaron detección de G. vaginalis en muestras uretrales con reportes desde 1,5 %, 4,2 % hasta 14 % con manifestaciones clínicas de uretritis. Otros reportes indican 4,5 %, 5 %, 6,3 %, 7,2 % y 14,5 % sin uretritis. Dos estudios de infecciones del tracto urinario presentan porcentajes de 30,8 % y 67 % de G. vaginalis en hombres con síntomas urinarios. G vaginalis se reporta en frotis rectal, semen e hisopados del prepucio, pero sin clara atribución de etiología patógena. Conclusión: Es recomendable la búsqueda de G. vaginalis en hombres con uretritis no gonocócica, balanopostitis, e infecciones del tracto urinario por su probable significado patógeno, mientras que su papel en semen en pacientes con infertilidad y en el frotis rectal, requiere más estudios de investigación.

Introduction: Gardnerella vaginalis has been isolated from urine, semen, urethral discharge, and endourethral, rectal, and foreskin swabs, in some cases associated with clinical manifestations. Urethritis and balanoposthitis have been described in different percentages. Rectal swab, semen, and foreskin findings must be carefully interpreted for clinical significance. It has been demonstrated that man acquires it from her sexual partners in its cohesive form. Objective: To explore the role of G. vaginalis as a cause of infections in men. Method: Bibliography was searched through PubMed/ Medline, Scopus Cochrane Library, SciELO Lilacs, Redalyc; Google Scholar, and providers like EBSCO and thesauros MeSH y DeCS. Results: Several publications show the detection of G. vaginallis in urethral samples with reports of 1,5%, 4,2%, even 14% of urethritis. Some other reports show a 4,5%, 5%, 6,3%, 7,2% and 14,5% without urethritis. Two studies of urinary tract infections show a 30,8% and 67% of G. vaginalis in men with urinary symptoms. G. vaginalis is reported in rectal smears, semen, and foreskin swabs but without clear attribution of pathogenic etiology. Conclusion: The search for G. vaginalis in men with non-gonococcal urethritis, balanoposthitis, or urinary tract infections is recommended due to its probable pathogenic significance, while its role in patients with infertility and rectal smears requires further investigation, due to the presence in semen.

Chronic osteomyelitis in canine penile bone: case report / Osteomielite crônica em osso peniano canino: relato de caso

A 10-year-old male mixed-breed dog was admitted for recurrent signs of urinary tract infection (UTI). Urinary bladder ultrasonography revealed decreased thickness of its wall with floating hyperopic particles within its lumen. Ultrasonography revealed a structure invading the dorsal wall of the penile urethral lumen, located in a segment distal to the bladder. Radiographies showed bone resorption with proliferation at the caudal aspect of the penile bone, stricture of the final aspect of the penile urethra, and no radiopaque images compatible with a urethrolith. Computed tomography showed bone proliferation causing stricture of the urethral lumen at two different sites. Presumptive diagnosis of penile neoplasia was considered more likely and the dog underwent penectomy along with orchiectomy and scrotal urethrostomy. Enterobacter spp. was cultured from the urine sample and antibiotic sensitivity tests revealed that the bacterium was susceptible to amikacin, imipenem, and meropenem. Histopathology revealed severe suppurative urethritis, bone resorption, and hyperostosis, suggestive of osteomyelitis of the penile bone. Neoplastic cells were not observed at any part of the examined tissue. The findings in the present case suggest that osteomyelitis of the penile bone should be included in differential diagnosis for partial and complete urethral obstruction in dogs with recurrent UTI.(AU)

Um cão mestiço, com 10 anos, foi admitido por sinais recorrentes de infecção do trato urinário (ITU). A ultrassonografia da bexiga urinária revelou diminuição da espessura de sua parede com partículas flutuantes dentro de seu lúmen. A ultrassonografia demonstrou estrutura invadindo a parede dorsal do lúmen da uretra peniana, localizada em segmento distal à bexiga. Radiografias evidenciaram reabsorção óssea com proliferação no aspecto caudal do osso peniano, estenose do aspecto final da uretra peniana e ausência de imagens radiopacas compatíveis com uretrólito. Pela tomografia computadorizada, observou-se proliferação óssea causando estreitamento da luz uretral em dois locais diferentes. Diagnóstico presuntivo de neoplasia peniana foi considerado mais provável e o cão foi submetido à penectomia, juntamente com orquiectomia e uretrostomia escrotal. Enterobacter spp. foi cultivada da amostra de urina e testes de sensibilidade revelaram susceptibilidade ao amicacina, imipenem e ao meropenem. A histopatologia revelou uretrite supurativa grave, reabsorção óssea e hiperostose compatível com osteomielite do osso peniano. Células neoplásicas não foram observadas em nenhuma parte do tecido examinado. Os achados do presente caso sugerem que a osteomielite do osso peniano deve ser incluída no diagnóstico diferencial de obstrução uretral parcial e completa em cães com ITU recorrente.(AU)

Prevalence of Co-infection with Gonorrhoea and Non-Gonococcal Urethritis in Males with Urethral Discharge Genitourinary Clinic, Hospital Kuala Lumpur: A 5-year study between 2011 – 2015

Introduction:Dual infection with Neisseria gonorrhoeae and Chlamydia sp has been reported in several studies worldwidein men presenting with urethral discharge. The rate of co-infection has been reported to be between 1.5 to 51%.This study aims to determine the demographic characteristics and sexual behaviour of men diagnosed to haveurethritis.Methods:This is a retrospective study on all men who presented with urethral discharge and diagnosed to havegonococcal (GU) and non-gonococcal urethritis (NGU) for the year 2011 to 2015 in Genito-UrinaryMedicine Clinic (GUM), Hospital Kuala Lumpur. The case notes were retrieved and reviewed.Results:There were a total of 307 men who attended the GUM clinic with urethral discharge. The mean ageof patients was 26.4 years (range 16-57 years). Majority (64.5%) were in the age group between 20-29 years. Around 95% were Malaysians and of these about 80% were Malays. Thirty-seven patients(12%) completed their tertiary education. There were 24 patients (8%) documented to have substanceabuse. Majority (78%) were heterosexual. About 36% of patients had 2 or more partners (range 2-10)6 months before the symptoms developed. The most common cause of urethritis was gonococcalurethritis (66.4%), followed by NGU (24.4%). Among the NGU, nine were detected to have Chlamydiasp infection (12%). Co-infection with Neisseria gonorrhoea and Chlamydia sp were detected in 28men (9.1%). Seven (2.3%) were HIV seropositive.Conclusion:Majority of males diagnosed with gonorrhoea were heterosexuals acquired mainly via casual partners.About 10% had co-infection with Neisseria gonorrhoeae and Chlamydia sp.

120 cases of non gonococcal urethritis mycoplasma and chlamydia infection and drug resistance status / 中国基层医药

Objective To investigate non gonococcal urethritis mycoplasma and chlamydia infection and drug sensitivity status.Methods From June 2014 to December 2014,120 cases of non gonococcal urethritis patients in our hospital were given chlamydia trachomatis,ureaplasma,mycoplasma detection and mycoplasma culture and drug sensitivity test of mycoplasma.Mycoplasma and chlamydia test results were compared between male and female patients.Positive drug sensitivity test results of ureaplasma urealyticum (Uu) and mycoplasma hominis (Mh) were observed.Results Among the 120 patients with positive detection,the proportion of Uu was the highest,up to 41.67％ (50/120);the second was Mh,accounting for 31.67％ (38/120).The detection rate of Uu in women (57.14％)was significantly higher than that in males (28.13％),and the difference was statistically significant (x2 =10.35,P ＜ 0.05).The susceptibility of mycoplasma to pristinamycin susceptible rate highest,Uu and type mycoplasma reached 100.00％;followed by doxycycline,the susceptibility of Uu reached 98.00％ and the susceptibility of Mh to 100.00％;sensitive rates of Uu and Mh to josamycin were 96.00％ and 90.48％.The sensitive rates of Uu and Mh to tetracycline were 92.00％ and 90.48％ respectively.Conclusion The mycoplasma infection was mainly caused by Uu.Clinical treatment of mycoplasma infection can be based on the drug sensitivity test results to reasonably choose antibiotics,and sensitive rates of pristinamycin,doxycycline were higher.

Genotyping of Chlamydia trachomatis strains from male patients with urethritis in sexually transmitted disease clinic / 中华皮肤科杂志

Objective To investigate the serovar distribution of Chlamydia trachomatis (Ct) isolated from male patients with urethritis in sexually transmitted disease (STD) clinic.Methods Urine specimens were collected from male patients with urethritis in STD clinic at Hospital of Dermatology,Chinese Academy of Medical Sciences between January 2013 and December 2013.Fluorescence-based quantitative PCR was performed to detect Ct DNA in these specimens.DNA was extracted from Ct-positive urine specimens,and nested PCR was conducted to amplify the VS1-VS2 regions of the outer membrane protein A (ompA) gene,followed by gene sequencing.The resulting sequences were aligned to reference sequences by the DNAStar5.0 software to determine Ct serovars.Results A total of 432 urine specimens were collected,and 33.1％ (143/432) of them were positive for Ct.The VS1-VS2 regions of the ompA gene were amplified from 127 out of the 143 Ct-positive specimens,but not from the other 16 specimens.Nine serovars were identified by gene sequencing among the 127 specimens,including serovar E (29 strains,22.83％),F (28 strains,22.05％),D (19 strains,14.96％),G (16 strains,12.60％),J (16 strains,12.60％),K (8 strains,6.30％),H (5 strains,3.94％),I (3 strains,2.36％) and B (3 strains,2.36％),and Ct serovars E,F,D,J and G accounted for 85.02％ among all the strains.Synonymous mutations were identified in 14 out of the 127 strains when compared with reference strains.Conclusions E,F,D and G serovars were the main Ct serovars in male patients with urethritis in STD clinic.The proportion of Ct serovar E strain was decreased,but that of serovar J strain was increased compared with 20 years ago.

Detection of Trichomonas vaginalis in male patients with urethritis by nested PCR / 中华皮肤科杂志

Objective To establish two nested PCR assays for detection of Trichomonas vaginalis in urine samples from male patients with urethritis,and to evaluate their diagnostic value.Methods One thousand and eighty-eight male patients with urethritis were enrolled from sexually transmitted disease (STD) clinic in the Hospital of Dermatology,Chinese Academy of Medical Sciences and Peking Union Medical College between April 2011 and December 2013.Urethral swabs were collected followed by smear testing,wet mount microscopic examination of Trichomonas vaginalis,and cultivation of Neisseria gonorrhoeae.Urine specimens were also obtained from these patients followed by DNA extraction.Two nested PCR assays were developed and performed to amplify the repeat genomic sequence and β-tubulin gene of Trichomonas vaginalis.Results Trichomonas vaginalis was detected in none of these swab specimens by wet mount microscopy,but in 29 (2.67％) of the urine specimens by either of the two nested PCR assays.Moreover,the positive specimens detected by the two nested PCR assays were completely consistent.Conclusion Compared with wet mount microscopy,nested PCR has higher sensitivity and specificity in detection of Trichomonas vaginalis in urine samples from male patients.
