[Balanoposthitis in the clinical practice of a urologist and dermatovenereologist: an interdisciplinary problem].

Balanoposthitis is a common inflammatory disease of the male genitals, which occurs more often in uncircumcised men. The cause of balanoposthitis can be an infectious, inflammatory or autoimmune process, as well as traumatization. In most cases, after proper intimate hygiene and the use of neutral moisturizers, the symptoms of balanoposthitis are completely stopped. In the case of torpid course of balanoposthitis and in the absence of improvement after drug therapy, it is necessary to exclude the malignant process. In the review article, the authors present the data of modern scientific research on the qualitative and quantitative composition of the microbiome in balanoposthitis. Differences in the composition of the microbiome were revealed in patients with balanoposthitis and healthy patients from the control group with excess foreskin. It was found that in patients with balanoposthitis, a impaired in hydration of the skin of the glans penis was revealed. Staphylococcus warneri and Prevotella bivia are the most common species associated with balanoposthitis and positively correlate with the severity of the disease. Candida infection, as an etiological factor of balanoposthitis, often occurs in children and may be associated with diaper rash. The prevalence of Gardnerella vaginalis as a pathogen in the male urogenital tract has not been fully studied. Currently, there are no reliable scientific studies that make it possible to attribute G. vaginalis to the etiological factor of balanoposthitis in men. However, it should be borne in mind that balanoposthitis may have a polymicrobial and synergistic etiology with the participation of G. vaginalis and anaerobic bacteria in the lower genital tract of men. The review article is clearly illustrated with clinical examples of the disease from the personal practice of the authors.

Reactive arthritis: images.

Reactive arthritis is an extremely rare spondyloarthritis that affects the peripheral joints and spine, resulting in common symptoms such as arthritis, urethritis, conjunctivitis, and mucocutaneous lesions. On rare occasions, oral lesions such as circinate erosions on the hard and soft palate, gums, tongue, and cheeks may occur. Reactive arthritis may develop during or after genitourinary or gastrointestinal bacterial infections such as Shigella, Salmonella, Yersinia, and Chlamydia. A 36-year-old man presented with circinate balanitis, urethral discharge, oligoarthralgia, conjunctivitis, lymphadenopathy, pharyngitis, and erythematous lesions on the palate. Culture examination showed presence of Neisseria gonorrhoeae and antibiotic treatment resulted in improvement of conjunctivitis and the lesions on the penis. However, severe oligoarthralgia, palatal erosions that increased in severity and size, and depilated areas on the tongue were observed. The definitive diagnosis was reactive arthritis. The prevalence of sexually transmitted infections is increasing, highlighting the need to increase awareness of associated risks such as reactive arthritis. Moreover, consideration of non-specific oral manifestations in a systemic context may aid in effective diagnosis and treatment, suggesting the need for multidisciplinary teams.

[Mycoplasma genitalium and male urogenital diseases: An update].

Mycoplasma genitalium (MG) was first isolated by Tully from the urinary tract of the male patient with non-gonococcal urethritis (NGU) in 1981. MG is extremely difficult to be cultured and was rarely studied until the development and application of molecular biology technology. The research on MG in China is still in the primary stage. However, relevant studies abroad have found that it is an important pathogen causing human genitourinary tract infection and spreading worldwide. Male MG infection is reportedly related to NGU, prostatitis, epididymitis, balanoposthitis, male HIV infection, and male infertility. This review outlines the advances in the studies of MG in male urogenital diseases.

Streptococcus pyogenes as the cause of vulvovaginitis and balanitis in children.

BACKGROUND: Streptococcus pyogenes (group A Streptococcus) is the etiological agent of perineal infection in children, consisting of perianal infection, vulvovaginitis and balanitis. If it is not properly diagnosed and treated, it can persist for many months and can cause severe complications. Furthermore, treatment with penicillin can be followed by failures and recurrences. METHODS: We report here the prevalence of S. pyogenes isolates in genital tract specimens from girls (n = 1692) with symptoms of vulvovaginitis and from boys (n = 52) with balanitis in the municipality of Nis, Southeast-Serbia (the Western Balkans) in a 10 year period, and the seasonal distribution, patient age and sensitivity to bacitracin and antimicrobial drugs used in the treatment of streptococcal infection. RESULTS: Streptococcal vulvovaginitis was diagnosed in 2.30% of examinees. Of those cases, 64.10% were detected from April to September, and it was most common (71.79%) in girls aged 3-7 years. Streptococcal balanitis was diagnosed in two instances: in a 4-year-old boy and in a 7-year-old boy. S. pyogenes strains resistant to bacitracin were identified in five girls. Two isolates with M phenotype and five isolates with cMLSB phenotype were identified. CONCLUSIONS: Streptococcal vulvovaginitis was diagnosed less often in the present study, but it was still far more common than streptococcal balanitis in childhood. Bacitracin resistance of S. pyogenes strains should be taken into account in routine microbiological identification, and the detection of S. pyogenes isolates resistant to erythromycin requires surveillance in the present geographical territory.

Balanitis: A Unique Presentation of Diabetes in an Elderly Male.

While diabetes is a common medical condition, the initial presentation of patients with diabetes may vary. In some cases, different types of infections or inflammatory conditions may prompt a patient to seek medical attention. Males may present to their primary care provider with a bothersome inflammation of the penis that may be the first recognition of previously undiagnosed diabetes. Balanitis is an inflammation of the glans of the penis that may prompt a patient to seek medical care. While there are several different causes of balanitis, underlying medical conditions such as uncontrolled diabetes have been associated with balanitis. The genital irritation prompts patients to seek medical evaluation, and at that point diabetes is diagnosed. It is important for pharmacists to recognize that balanitis is a potential though uncommon type of diabetes presentation. It is also important for pharmacists to review other aspects of diabetes care once a patient is diagnosed with diabetes.

Balanoposthitis and Penile Edema: Atypical Manifestations of Primary Syphilis.

The typical finding in primary syphilis stage is a unique, painless chancre with indurated borders. We report a case of primary syphilis presenting as erosive and crusted balanoposthitis with an underlying chancre, penile edema, and bilateral inguinal lymphadenopathy in a heterosexual man.

[MICROBIOLOGICAL ASPECTS OF INFECTIOUS BALANOPOSTHITIS].

Treatment and prevention of diseases of the male reproductive organs largely influence male population fertility and the health of the future generations. This review summarizes current views on the problem of infectious balanoposthitis and presents generalized information on its pathogens. Refined classification and diagnostic workup are provided. The important role of pathogenic microflora in the formation of the glans penis and foreskin inflammation is shown. Importance of Enterococcus spp. in the etiology of balanoposthitis is demonstrated. The modern treatment regimens and prevention of balanoposthitis are described.

Methylene blue@silver nanoprisms conjugates as a strategy against Candida albicans isolated from balanoposthitis using photodynamic inactivation.

Balanoposthitis can affect men in immunocompromised situations, such as HIV infection and diabetes. The main associated microorganism is Candida albicans, which can cause local lesions, such as the development of skin cracks associated with itching. As an alternative to conventional treatment, there is a growing interest in the photodynamic inactivation (PDI). It has been shown that the association of photosensitizers with metallic nanoparticles may improve the effectiveness of PDI via plasmonic effect. We have recently shown that the association of methylene blue (MB), a very known photosensitizer, with silver prismatic nanoplatelets (AgNPrs) improved PDI of a resistant strain of Staphylococcus aureus. To further investigate the experimental conditions involved in PDI improvement, in the present study, we studied the effect of MB concentration associated with AgNPrs exploring spectral analysis, zeta potential measurements, and biological assays, testing the conjugated system against C. albicans isolated from a resistant strain of balanoposthitis. The AgNPrs were synthesized through silver anisotropic seed growth induced by the anionic stabilizing agent poly(sodium 4-styrenesulfonate) and showed a plasmon band fully overlapping the MB absorption band. MB and AgNPrs were conjugated through electrostatic association and three different MB concentrations were tested in the nanosystems. Inactivation using red LED light (660 nm) showed a dose dependency in respect to the MB concentration in the conjugates. Using the highest MB concentration (100 µmol⋅L-1) with AgNPr, it was possible to completely inactivate the microorganisms upon a 2 min irradiation exposure. Analyzing optical changes in the conjugates we suggest that these results indicate that AgNPrs are enhancers of MB photodynamic action probably by a combined mechanism of plasmonic effect and reduction of MB dimerization. Therefore, MBAgNPrs can be considered a suitable choice to be applied in PDI of resistant microorganisms.

Squamous cell carcinoma of the penis and topical combination corticosteroid products: a cautionary case.

Squamous cell carcinoma of the penis is fairly uncommon, but an important clinical entity with significant patient morbidity. Early diagnosis is important to allow for conservative management and to avoid aggressive surgical resection. We present a case of an invasive squamous cell carcinoma of the glans penis, which was treated with topical antifungals and corticosteroids for 2 years prior to diagnosis, necessitating partial glansectomy.

Prevalence of specific and phylogenetically closely related genotypes in the population of Candida albicans associated with genital candidiasis in China.

Genitourinary candidiasis, which is most frequently caused by Candida albicans, is a common problem worldwide. The pathogenesis of the infection, especially recurrence of the infection, remains to be elucidated. This study analyzed 199 independent Chinese C. albicans isolates using multilocus sequence typing (MLST) and microsatellite typing, with the focus on the isolates associated with vulvovaginal candidiasis (VVC) of Chinese women. MLST data of 221 vaginal isolates from other countries available from the consensus MLST database of C. albicans were retrieved for comparison. A total of 124 diploid sequence types (DSTs) were recognized from the Chinese C. albicans isolates, among which, 98 (79.0%) have not been reported in the MLST database of the species. The majority of the VVC (71.6%) and balanitis (92.3%) isolates from China were located in clade 1 of C. albicans; while only 40.6% of the vaginal isolates and 7.8% of the oral isolates from healthy volunteers were found in the same clade. Furthermore, 69.1% of the VVC and 84.5% of the balanitis isolates concentrated in a cluster of clade 1 with DST 79 as the primary founder. The isolates in this cluster possessed microsatellite genotypes CAI 30-45, CAI 32-46 and their close derivatives. Interestingly, a remarkable difference in genotype distribution patterns between Chinese and non-Chinese vaginal isolates of C. albicans was observed. Only 11.3% of the non-Chinese vaginal isolates compared were located in the cluster concentrated with Chinese VVC isolates. The results suggest significant association of specific and genetically similar genotypes with genital infections in China.

High prevalence and resistance rates to antibiotics in anaerobic bacteria in specimens from patients with chronic balanitis.

Aim of the study was to assess both prevalence and antibiotic resistance in anaerobic bacteria from glans penis skin of 70 adults. Strain susceptibility was determined by breakpoint susceptibility test or E test. In 9 asymptomatic, 48 untreated and 13 treated symptomatic patients, anaerobes were found in 22.2%, 70.8% and 53.3%, respectively. Gram-positive strains (GPAs) were 2.2-fold more common than Gram-negative ones. Prevalent Gram-negative (GNAs) and GPAs were Prevotella spp. and anaerobic cocci, respectively. Clostridium difficile strain was found in an untreated patient. In GNAs, resistance rates to amoxicillin, metronidazole, clindamycin, tetracycline, levofloxacin, and amoxicillin/clavulanate were 42.1, 0, 52.6, 53.3, 86.7 and 5.2%, respectively. In GPAs, the resistance rates to metronidazole, clindamycin, tetracycline, levofloxacin and amoxicillin/clavulanate were 18.2, 34.1, 52.6, 36.8 and 0%, respectively. In conclusion, anaerobes were 1.6-fold more frequent in untreated symptomatic patients compared with other patients, suggesting their participation in development of chronic balanitis. GPAs were more common than GNAs. The resistance rates to amoxicillin, clindamycin, tetracycline, and levofloxacin were high. Most active agents were metronidazole and amoxicillin/clavulanate. Resistance in anaerobes varies according to sites of specimens and years of study.

Association of Mycoplasma genitalium with balanoposthitis in men with non-gonococcal urethritis.

OBJECTIVE: To determine whether Mycoplasma genitalium is associated with balanitis and/or posthitis in a previous study of the role of M genitalium in men with acute non-gonococcal urethritis (NGU). METHODS: In a previous study of men with acute NGU, the existence of balanitis and/or posthitis was recorded. Chlamydia trachomatis, M genitalium and ureaplasmas were sought in urethral swabs and urine using a direct fluorescent antibody test and in-house PCR, an in-house PCR and a culture method, respectively. Men were treated with doxycycline or erythromycin. RESULTS: M genitalium was associated significantly (p = 0.01) with balanitis and/or posthitis in 114 men with acute NGU. This association persisted when there was control for C trachomatis and urethral discharge (p = 0.021, OR 4.1, 95% CI 1.2 to 13.5). C trachomatis and ureaplasmas were not associated with balanitis and/or posthitis. CONCLUSION: Detection of M genitalium in men with acute NGU was associated significantly with balanitis and/or posthitis. The association is biologically plausible and may have a role in HIV-1 transmission and susceptibility.

Direct impression on agar surface as a diagnostic sampling procedure for candida balanitis.

BACKGROUND: The diagnosis of candida balanitis should be based upon both clinical and mycological data. The procedure of material collection is a critical issue to confirm or rule out the clinical diagnosis of candida balanitis. OBJECTIVE: To compare direct impression of the glans on the agar surface of solid culture media with the collection of genital exudates with cotton swab for the diagnosis of candida balanitis. METHODS: A prospective cross-sectional study was carried out during a 36-month period. Sexually transmitted disease clinic attendees with balanitis and asymptomatic men were included. Specimens for yeast culture were collected from the glans penis and inner preputial layer using the direct impression on CHROMagar candida medium and by swabbing with a sterile cotton swab. RESULTS: Among 478 men enrolled, 189 had balanitis. The prevalence of candida balanitis was 17.8% (85/478) confirmed after culture by direct impression; the swab method detected only 54/85 (63.5%) of these men. Of the 289 asymptomatic men, 36 (12.5%) yielded Candida spp; the swab method detected only 38.9% of these men. The risk of having candida balanitis is 8.9 (IC 95% 2.48 to 32.04) whenever the number of candida colonies recovered by direct impression was greater than 10. CONCLUSIONS: Direct impression on CHROMagar candida medium resulted in the highest Candida spp recovery rate. More than 10 colonies yielded by impression culture were statistically associated with candida balanitis. This method shows the ideal profile for sampling the male genital area for yeasts and should be included in the management of balanitis.

Characterization of Streptococcus pyogenes isolated from balanoposthitis patients presumably transmitted by penile-oral sexual intercourse.

Streptococcus pyogenes is indigenous to the human pharynx and causes acute pharyngitis. Balanoposthitis is an inflammatory disease of the glans and the foreskin. However, balanoposthitis caused by S. pyogenes is not widely recognized as a sexually transmitted disease. In addition, bacteriological features of the isolates causing balanoposthitis are unclear. The four S. pyogenes strains isolated from adult balanoposthitis were examined. We performed emm typing, T antigen typing, RAPD assay, PCR assay for the streptococcal pyrogenic exotoxin-related genes and antibiotic-resistant genes, and antibiotic susceptibility assay. All four strains were suspected to be transmitted by penile-oral sexual intercourse, were found to be different by genetic analysis, and also harbored some antibiotic-resistant factors. We propose that S. pyogenes should be considered as a causative agent of sexually transmitted disease. The drug resistant S. pyogenes must be taken into account when balanoposthitis patients are treated with antibiotic.

Biased genotype distributions of Candida albicans strains associated with vulvovaginal candidosis and candidal balanoposthitis in China.

BACKGROUND: Vulvovaginal candidosis (VVC), which is most frequently caused by Candida albicans, is one of the most common vaginal infections and is a common problem worldwide. Despite the fact that extensive epidemiological studies have been performed, what triggers VVC, especially recurrence of the infection, is still uncertain. METHODS: Genotypes of C. albicans strains associated with VVC and balanoposthitis and of strains isolated from samples from vaginas of asymptomatic women and from various extragenital sites were determined with use of C. albicans microsatellite locus I polymorphism analysis. Genetic similarity of representative strains with the same and different C. albicans microsatellite locus I genotypes were examined by sequence analysis of housekeeping genes CaADP1, CaSYA1, and CaVPS13. RESULTS: The C. albicans microsatellite locus I genotypes of independent C. albicans strains isolated from samples from extragenital sites were mostly of individual specificity. In contrast, strains associated with VVC were mainly concentrated to a few genotypes, with genotypes 30-45 and 32-46 being the most common. The overall frequencies of the 2 genotypes among C. albicans strains from vaginal samples from patients with VVC and from asymptomatic women were 59.1% and 24.0%, respectively (P = .002); the frequencies among patients with complicated VVC and among patients with uncomplicated VVC were 69.2% and 35.7%, respectively (P = .003). A similar genotype distribution pattern of C. albicans strains associated with balanoposthitis was also revealed. The genetic similarity of strains with the dominant genotypes associated with both VVC and balanoposthitis was confirmed by sequence analysis of the 3 genes. CONCLUSIONS: The results suggest the existence of vaginopathic C. albicans strains with enhanced virulence and tropism for the vagina and the high possibility of sexual transmission of genital C. albicans infection. Identification of specific genotypes that correlate with severity of VVC is also of diagnostic and therapeutic significance.

Foreskin length in uncircumcised men is associated with subpreputial wetness.

This study was performed to identify possible factors associated with penile wetness, defined as the observation of a diffuse homogenous film of moisture on the surface of the glans and coronal sulcus, in men attending a sexually transmitted infection clinic. Genital examination was undertaken in 422 uncircumcised men and any degree of subpreputial wetness observed was recorded. The degree of visibility of the urinary meatus on direct inspection was also assessed. Subjects were asked whether they retracted the foreskin while urinating and how long since they had last passed urine. Penile wetness was observed in 13.0% of the men and was more common in those whose foreskin covered the urinary meatus on direct inspection (17.4% vs. 4.9%) and those with balanitis (33.3%). On multivariate analysis, penile wetness was independently associated with balanitis, non-specific urethritis/chlamydia, reporting sex with another man and having a visible urinary meatus on direct inspection. Penile wetness was not associated with retracting the foreskin while passing urine or duration since last passed urine. Men with a foreskin covering the urinary meatus on direct observation should be advised about the benefits of good genital hygiene if penile wetness was observed.

Syphilis mimicking Reiter's syndrome in an HIV-positive patient.

A 38-year-old man with HIV infection presented with panuveitis, urethritis, and a papulosquamous eruption on his palms and soles. Careful physical and laboratory examination led to the diagnosis of syphilitic keratoderma, uveitis, and balanitis. The patient was successfully treated with penicillin and prednisone therapy. Because the initial presentation was difficult to distinguish from the symptoms of Reiter's syndrome, a high degree of clinical suspicion was required to accurately diagnose syphilis, a curable and potentially fatal disease.
