RESUMO

Infective endocarditis (IE) is a condition with low prevalence but high mortality rates within intensive care units. Microbiologically, most cases are attributed to Gram-positive cocci, while Gram-negative bacilli are less commonly involved. This case report describes a patient with IE caused by Citrobacter koseri (C. koseri) with secondary bacteremia due to blunt testicular trauma and epididymitis. We conducted a review of the literature to assess the clinical and associated risk factors of this underreported condition. Elderly and urinary tract infections could be associated with this entity. Cefazolin was used as the final targeted treatment. The use of precision medicine in IE is required for specific interventions.

Infection of the heart valve from testicular injury: a case study and review of medical literature Infective endocarditis (IE) is a serious but rare infection that can lead to death, especially in intensive care units. Typically, it's caused by certain types of bacteria, but our case study focuses on a patient whose IE was caused by a less common bacterium called Citrobacter koseri (C. koseri). This infection occurred after the patient experienced blunt trauma to the testicles, leading to a bloodstream infection. We looked at other similar cases in medical literature and found that older age and urinary tract infections might increase the risk of this type of IE. In this case, IE caused by this unusual bacteria was treated with cefazolin.

RESUMO

This study included 47 free-ranging bats from the State of Minas Gerais, Brazil. Six bats (12.8%) had genital inflammatory lesions, and two of them (one Artibeus lituratus and one Glossophaga soricina, a frugivorous and a nectarivorous, respectively) were diagnosed with Brucella sp. infection through PCR, and antigens in intralesional macrophages were detected using immunohistochemistry.

RESUMO

Chlamydia trachomatis is an obligate intracellular pathogen and the leading bacterial cause of sexually transmitted infections worldwide. Chlamydia trachomatis genovars L1-L3 are responsible for lymphogranuloma venereum (LGV), an invasive sexually transmitted disease endemic in tropical and subtropical regions of Africa, South America, the Caribbean, India and South East Asia. The typical signs and symptoms of C. trachomatis LGV urogenital infections in men include herpetiform ulcers, inguinal buboes, and/or lymphadenopathies. Since 2003, endemic cases of proctitis and proctocolitis caused by C. trachomatis LGV emerged in Europe, mainly in HIV-positive men who have sex with men (MSM). Scarce data have been reported about unusual clinical presentations of C. trachomatis LGV urogenital infections. Herein, we report a case of a 36-year-old heterosexual, HIV-negative male declaring he did not have sex with men or trans women, who presented to the Urology and Andrology outpatient clinic of a healthcare center from Cordoba, Argentina, with intermittent testicular pain over the preceding 6 months. Doppler ultrasound indicated right epididymitis and funiculitis. Out of 17 sexually transmitted infections (STIs) investigated, a positive result was obtained only for C. trachomatis. Also, semen analysis revealed oligoasthenozoospermia, reduced sperm viability as well as increased sperm DNA fragmentation and necrosis, together with augmented reactive oxygen species (ROS) levels and the presence of anti-sperm IgG autoantibodies. In this context, doxycycline 100 mg/12 h for 45 days was prescribed. A post-treatment control documented microbiological cure along with resolution of clinical signs and symptoms and improved semen quality. Strikingly, sequencing of the ompA gene revealed C. trachomatis LGV L2 as the causative uropathogen. Remarkably, the patient did not present the typical signs and symptoms of LGV. Instead, the infection associated with chronic testicular pain, semen inflammation and markedly reduced sperm quality. To our knowledge, this is the first reported evidence of chronic epididymitis due to C. trachomatis LGV L2 infection in an HIV-negative heterosexual man. These findings constitute important and valuable information for researchers and practitioners and highlight that C. trachomatis LGV-L2 should be considered as putative etiologic agent of chronic epididymitis, even in the absence of the typical LGV signs and symptoms.

RESUMO

We report a case of urethral obstruction due to seminal vesiculitis in a Dorper sheep, with symptoms of anuria, rectal prolapse, orchitis/epididymitis, and uroperitoneum and biochemical tests indicating severe azotemia. The animal died due to advanced azotemia, and necropsy revealed kidneys with cortical and medullary necrosis, pyelonephritis of renal calyces, hydronephrosis, ruptured and necrotic bladder, and vesicular, bulbourethral, and ampoule accessory sex glands. There was prostate hyperplasia that revealed a large amount of pus in the cross section, which was also observed bilaterally in the epididymis and right testis. Morphotintorial and biochemical analyses of bacteria obtained from microbiological culture revealed Corynebacterium sp. and Escherichia coli. Infection, hyperplasia, and abscessation of accessory sex glands caused urethral compression, resulting in an obstructive condition, similar to urolithiasis, in addition to bacteremia. Hyperplastic seminal vesiculitis, although rare, must be included among the differential diagnoses of obstructive processes in the urinary tract of sheep.

Relata-se um caso de obstrução uretral decorrente de vesiculite seminal em carneiro da raça Dorper, com quadro de anúria, prolapso retal, orquite/epididimite e uroperitôneo, com exames bioquímicos indicativos de severa azotemia. Devido ao quadro avançado de azotemia, o animal faleceu e, na necropsia, foi observado:: rins com necrose de cortical e medular, pielonefrite dos cálices renais e hidronefrose, bexiga rompida e necrosada, assim como glândulas sexuais acessórias vesiculares, bulbouretrais e ampola. Havia hiperplasia de próstata que, ao corte transversal, revelou grande quantidade de pus, que também foi observado bilateralmente no epidídimo e no testículo direito. As análises morfotintoriais e bioquímicas das bactérias obtidas a partir do cultivo microbiológico foram compatíveis com Corynebacterium sp. e Escherichia coli. A infecção, a hiperplasia e a abscedação das glândulas sexuais acessória, causaram compressão uretral, levando a um quadro obstrutivo, semelhante à urolitíase, somado à bacteremia. A vesiculite seminal hiperplásica, apesar de rara, deve ser incluída entre os diagnósticos diferenciais dos processos obstrutivos do trato urinário de carneiros.

RESUMO

Objective: This proof-of-principle aims to develop an index to aid the differential diagnosis of disorders affecting testicular and/or epididymis. A total of 202 subject data were evaluated in two groups: fertile men with children naturally conceived within 1 year of unprotected intercourse (n = 36) and infertile men (n = 166) who had attempted a pregnancy more than 1 year with unprotected intercourse. Materials and methods: Semen parameters (sperm count, vitality, motility, morphology, and hypoosmotic swelling test [HOST]) were evaluated. The index was calculated by dividing the percentage HOST by the percentage of sperm progressive motility in the fertile group (n = 36). Results: A normal range from 1.23 to 1.53 was determined. Using this index, the outcomes of semen analysis from infertile men were grouped in three study groups: below 1.23 (n = 24), normal (n = 44), and higher than 1.53 (n = 98). These parameters were significantly decreased in semen with normal range (p < 0.01) and in indexes higher than 1.53 (p < 0.0001). Receiver operating characteristic curves compared progressive motility and morphology in infertile men with indexes higher than 1.53 shows that semen samples with normal sperm progressive motility and morphology did not suggest dysfunctions in testis and epididymis. Semen samples with asthenozoospermia suggested epididymal dysfunction (area under the curve [AUC] 0.889, confidence interval [CI] 0.783-1), whereas semen samples with teratoasthenozoospermia suggested dysfunction in both testicles and epididymis (AUC 0.891, CI 0.77-1). Conclusions: The current index proof-of-principle of the success of such a strategy provides valuable information about whether a disorder individually affects testicular and/or epididymal function.

Objetivo: Esta prueba de principio tiene como objetivo desarrollar un índice que ayude al diagnóstico diferencial de los trastornos testiculares y/o epidídimales. Métodos: Se evaluaron 202 individuos divididos en dos grupos: hombres fértiles con hijos concebidos de forma natural en el plazo no mayor a un año (n = 36) y hombres infértiles (n = 166), los cuales habían intentado un embarazo por más de un año. Se evaluaron los parámetros seminales (concentración, viabilidad, movilidad, morfología y prueba de hinchazón hipoosmótica [HOST]). El índice se calculó dividiendo el porcentaje de HOST por el porcentaje de movilidad espermática progresiva en el grupo fértil (n = 36). Resultados: Se determinó un rango normal de 1,23 a 1,53. Utilizando este índice, los resultados del análisis del semen de los hombres infértiles se agruparon en tres grupos de estudio: por debajo de 1,23 (n = 24), normal (n = 44) y superior a 1,53 (n = 98). En contraste, estos parámetros disminuyeron significativamente en el semen de rango normal (p < 0,01) y en los índices superiores a 1,53 (p < 0,0001). Las curvas ROC comparadas con la movilidad espermática progresiva y la morfología en los hombres infértiles con índices superiores a 1,53 muestran que las muestras de semen con movilidad progresiva y morfología normales no sugieren disfunciones en los testículos y epidídimos. Las muestras de semen con astenozoospermia sugerirían una disfunción del epidídimo (AUC 0,889, IC 0,783-1), mientras que las muestra de semen que presentaban teratoastenozoospermia sugerirían una disfunción tanto en los testículos como en el epidídimo (AUC 0,891, IC 0,77-1).

RESUMO

Invasive bladder Aspergillosis has only been reported in six publications so far. A 74-year-old male, presented to the emergency department with fever, abdominal pain, and right testicular enlargement. Abdominal computed tomography concluded a bladder tumor and testicular ultrasound reported right epididymitis. Cystoscopy showed a bladder fungal mass, which was extracted with cystotomy. Pathological findings reported Aspergillus species. The patient was successfully treated with 4-week oral Isovuconazole. The first bladder Aspergillosis was published in 1978. The most recent case was published in 2020. Aspergillosis infection is extremely rare disease, treatment with Isavuconazole is efficient.

RESUMO

The testis is a potential target organ for SARS-CoV-2 infection. Our study intended to investigate any testicular involvement in mild-to-moderate COVID-19 men. We conduct a cross-sectional study in 18 to 55-year-old men hospitalised for confirmed COVID-19. A senior radiologist executed the ultrasound with multi-frequency linear probe in all participants, regardless of any scrotal complaints. Exclusion criteria involved any situation that could impair testicular function. Statistical analysis compared independent groups, classified by any pathological change. Categorical and numerical outcome hypotheses were tested by Fisher's Exact and Mann-Whitney tests, using the Excel for Mac, version 16.29 (p < .05). The sample size was 26 men (mean 33.7 ± 6.2 years; range: 21-42 years), all without scrotal complaints. No orchitis was seen. Eleven men (32.6 ± 5.8 years) had epididymitis (42.3%), bilateral in 19.2%. More than half of men with epididymitis displayed epididymal head augmentation > 1.2 cm (p = .002). Two distinct epididymitis' patterns were reported: (a) disseminated micro-abscesses (n = 6) and (b) inhomogeneous echogenicity with reactional hydrocele (n = 5). Both patterns revealed increased epididymal head, augmented Doppler flow and scrotal skin thickening. The use of colour Doppler ultrasound in mild-to-moderate COVID-19 men, even in the absence of testicular complaints, might be useful to diagnose epididymitis that could elicit fertility complications.

RESUMO

Whey-acidic protein four-disulfide core domain (WFDC) genes display putative roles in innate immunity and fertility. In mice, a locus on chromosome 2 contains 5 and 11 Wfdc genes in its centromeric and telomeric subloci, respectively. Although Wfdc genes are highly expressed in the epididymis, their contributions to epididymal function remain elusive. Here, we investigated whether Wfdc genes are regulated in response to lipopolysaccharide (LPS)-induced epididymitis, an inflammatory condition that impairs male fertility. We induced epididymitis in mice via (i) interstitial LPS injection into epididymal initial segment and (ii) intravasal LPS injection into the vas deferens towards cauda epididymis. Interstitial and intravasal LPS induced a differential upregulation of inflammatory mediators (interleukin 1 beta, interleukin 6, tumor necrosis factor, interferon gamma, and interleukin 10) in the initial segment and cauda epididymis within 72 h post-treatment. These changes were accompanied by a time-dependent endotoxin clearance from the epididymis. In the initial segment, interstitial LPS upregulated all centromeric (Slpi, Wfdc5, Wfdc12, Wfdc15a, and Wfdc15b) and five telomeric (Wfdc2, Wfdc3, Wfdc6b, Wfdc10, and Wfdc13) Wfdc transcripts at 24 and 72 h. In the cauda epididymis, intravasal LPS upregulated Wfdc5 and Wfdc2 transcripts at 24 h, followed by a downregulation of Wfdc15b and three telomeric (Wfdc6a, Wfdc11, and Wfdc16) gene transcripts at 72 h. Pharmacological inhibition of nuclear factor kappa B activation prevented LPS-induced upregulation of centromeric and telomeric Wfdc genes depending on the epididymal region. We show that LPS-induced inflammation differentially regulated the Wfdc locus in the proximal and distal epididymis, indicating region-specific roles for the Wfdc family in innate immune responses during epididymitis.

RESUMO

Polyarteritis nodosa (PAN) is a multisystemic disease that is characterized by the presence of necrotizing vasculitis of small and medium-sized blood vessels. Genital compromise is rare. Our patient presented a systemic disease associated to genital signs (penis and scrotum skin necrosis). A bilateral testicular and glans biopsy was performed and with PAN diagnosis, immunosuppressives treatment was realised for 6 weeks, with favorable progress.

RESUMO

Members of the genus Brucella cluster in two phylogenetic groups: classical and non-classical species. The former group is composed of Brucella species that cause disease in mammals, including humans. A Brucella species, labeled as Brucella sp. BCCN84.3, was isolated from the testes of a Saint Bernard dog suffering orchiepididymitis, in Costa Rica. Following standard microbiological methods, the bacterium was first defined as "Brucella melitensis biovar 2." Further molecular typing, identified the strain as an atypical "Brucella suis." Distinctive Brucella sp. BCCN84.3 markers, absent in other Brucella species and strains, were revealed by fatty acid methyl ester analysis, high resolution melting PCR and omp25 and omp2a/omp2b gene diversity. Analysis of multiple loci variable number of tandem repeats and whole genome sequencing demonstrated that this isolate was different from the currently described Brucella species. The smooth Brucella sp. BCCN84.3 clusters together with the classical Brucella clade and displays all the genes required for virulence. Brucella sp. BCCN84.3 is a species nova taxonomical entity displaying pathogenicity; therefore, relevant for differential diagnoses in the context of brucellosis. Considering the debate on the Brucella species concept, there is a need to describe the extant taxonomical entities of these pathogens in order to understand the dispersion and evolution.

RESUMO

The objective of this study was to experimentally evaluate the pathogenicity of an Actinobacillus seminis isolate named SAAS01 in goats. Animals were challenged with 2 mL of a suspension containing 1,5 × 108 CFU/mL of A. seminis (SAAS01 isolate) through the intrapreputial, epididymis tail, and conjunctival routes. Epididymis and testicular fragments were submitted to histopathological exam, and semen samples underwent microbiological and molecular diagnoses. Clinically, a unilateral increase in firm consistency was observed in the epididymis and testicles of two animals inoculated in epididymis tail and in one animal inoculated through conjunctival sac; this firmness continued until the day of euthanasia. Two goats inoculated through epididymis tail and conjunctival sac routes presented histopathological findings with macroscopically and microscopically significant changes. A. seminis was isolated from semen samples collected from goats inoculated through the epididymis tail and conjunctival sac routes. A. seminis DNA was amplified from six semen samples of three goats inoculated through the epididymis tail, two in conjunctival sac and one through intrapreputial route. The experimental infection model using goats confirmed the pathogenicity of the A. seminis isolate, demonstrating the predilection of the agent for the epididymis, with clinical signs, histopathological lesions, bacterial isolation, and a positive molecular diagnosis.

RESUMO

Chronic epididymitis and varicocele are frequently observed genital disorders in men consulting for couple infertility, but their impact on semen characteristics at the time of infertility consultation is still a matter of debate. We investigated 652 male partners of couples who had their first infertility consultation between 1999 and 2015 in Argentina. Men with chronic epididymitis (n = 253), Grade III varicocele (n = 106), and both conditions (n = 125) were compared with a control group (n = 168) composed of men without these disorders or any other recognized causes of male infertility. We showed that men who presented isolated chronic epididymitis were more likely to have high percentages of low sperm motility and abnormal sperm morphology as well as a high number of white blood cells. Men with isolated Grade III varicocele had low sperm production and motility and an increased percentage of abnormal sperm morphology. Finally, men who simultaneously presented chronic epididymitis with Grade III varicocele had a low sperm motility and increased percentage of abnormal sperm morphology as well as a high number of white blood cells. Physical examination of the genital organs may identify common disorders, potentially involved as causal factors of patient's infertility. These disorders are associated with specific seminal profiles that should help in identifying the best treatment from the available therapeutic options, effectiveness, safety, and allowing as much as possible natural conception.

RESUMO

Abstract Although histoplasmosis is generally a self-limited disease, disseminated infection can occur in patients lacking effective cell-mediated immunity, reaching virtually every organ, even the genitourinary tract in rare cases. We report a case of epididymo-orchitis in an immunocompetent 38-year-old bricklayer from the rural area of Villeta, Cundinamarca, Colombia. The patient presented with testicular pain and macroscopic scrotal changes requiring a left orchiectomy, with microbiological isolation and molecular confirmation of Histoplasma capsulatum.

RESUMO

O objetivo deste trabalho foi avaliar a patogenicidade, em ovinos, de uma cepa de Actinobacillus seminis isolada de caprino no Brasil. Foram utilizadas amostras de sêmen, punção e fragmentos de epidídimo, ducto deferente, testículos e glândulas seminíferas de dois caprinos (animais 1 e 2) e dois ovinos (animais 3 e 4), e foram realizados exame histopatológico, cultivo microbiológico e diagnóstico molecular. O inóculo foi preparado com solução salina na diluição de 10-2 correspondendo ao padrão 1,0 da escala de McFarland, com colônias previamente cultivadas de A. seminis e administrado no volume de 2 mL pelas vias intra-prepucial (animais 1 e 3) e na cauda do epidídimo (animais 2 e 4). Na avaliação clínica observou-se aumento unilateral de consistência firme após 30 dias no epidídimo e testículo do animal 4 que continuou até o dia da eutanásia, bem como o animal 1 apresentou discreto aumento unilateral dos testículos. As lesões macroscópicas e microscópicas observadas nos animais 3 e 4 foram compatíveis com aquelas causadas pela infecção por A. seminis. A. seminis foi isolado de material de punção e sêmen de um ovino (animal 4). Conclui-se que o modelo de infecção experimental utilizando caprinos e ovinos comprovou a patogenicidade da amostra de A. seminis, isolada de um caprino no semiárido brasileiro e reproduzida em um ovino, comprovando a predileção do agente pelo epidídimo, com quadro clinico, achados histopatológicos, isolamento bacteriano e diagnóstico molecular positivo.(AU)

The aim of this study was to evaluate, in sheep, the pathogenicity of an Actinobacillus seminis strain isolated from a goat in Brazil. Samples of semen, puncture and fragments of epididymis, deferent duct, testicles and seminal vesicles from two goats (animals 1 and 2) and two sheep (animals 3 and 4) were used, and histopathological, microbiological culture and molecular diagnoses were performed. The inoculum was prepared with saline solution at 10-2 dilution corresponding to 1.0 McFarland standard, with A. seminis colonies previously cultured and administered on 2mL volume by intra-preputial (animals 1 and 3) and epididymis tail (animals 2 and 4) routes. At clinical evaluation it were found unilateral swelling of firm consistency after 30 days in epididymis and testicle from animal 4 that continued until the day of euthanasia, as well as animal 1 shown discrete unilateral swelling of testicles. Gross and microscopic lesions in animals 3 and 4 were compatibles with that caused by A. seminis infection. A. seminis was isolated from material of puncture and semen of one sheep (animal 4). It is concluded that the experimental infection model using goats and sheep has proved the pathogenicity of the A. seminis strain isolated from a goat in the Brazilian semiarid and reproduced in a sheep, which confirm the prediletion of the agent for epididymis, with clinical signs, histopathological findings, bacterial isolation and positive molecular diagnosis.(AU)

The report is focused on the importance of ultrasonography as an auxiliary resource to the diagnosis of reproductive tract disorders. The ultrasonography of male gonads and annexes corroborates the findings obtained by palpation of the scrotum with details and noninvasively. Testicular ultrasonography is still sparsely used in sheep in order to detect diseases and when used early may even prevent and ensure that no subfertile breeder will spread its genes in the BS, ensuring good fertility rates.(AU)

RESUMO

Seroepidemiological study of Brucella ovis in sheep from Sergipe State was carried out to determine the seropositivity and infection distribution in rural properties and possible factors associated with infection. A total of 54 sheep properties were studied and 932 blood serum samples from animals older than six months were collected in the three regions of Sergipe State. All sera samples were examined by agar gel immunodiffusion (AGID). According to the serological tests, 46.30% (25/54) of the properties had serologic evidence of infection by B. ovis, with 4.40% of positive animals (41/932). Presence of sheep handler (OR=2.31) and properties with an area bigger than 50 ha (OR=1.98) were observed as factors associated with B. ovis infection, whereas the use of stall (OR=0.37) worked as a protective factor (OR=0.40). Thus, the presence of antibodies against B. ovis in Sergipe State was confirmed, and it highlights the importance of complementary studies to determine the specific health measures in herds to prevent this disease.(AU)

De acordo com o teste realizado, 46,30% (25/54) das propriedades apresentaram evidência sorológica de infecção por B. ovis, com uma positividade de 4,40% (41/932) dos animais. Como fatores associados à infecção por B. ovis, observaram-se a presença de tratador de ovinos (OR=2,31) e propriedades com área superior a 50 ha (OR=1,98) e como fator de proteção, a utilização de cabanha (OR=0,37). Assim, verificou-se a presença de anticorpos contra Brucella ovis nos ovinos do Estado e salienta-se a importância de estudos complementares para determinação de medidas sanitárias específicas para prevenir os rebanhos desta enfermidade.(AU)
