Immunodeviation towards T cell-mediated immune response in the testes of LPS-induced mouse epididymo-orchitis.

The testicular consequences of acute epididymo-orchitis remain largely unelucidated in long-term damage, which might be a neglected factor for male infertility. In this study, the differential phenotype of testicular immune cell subpopulations in lipopolysaccharide (LPS)-induced mouse epididymo-orchitis were analyzed by flow cytometry on day 1, day 7, and day 28. The number of macrophages, neutrophils, and myeloid-derived suppressor cells (MDSCs) steadily decreased in the testes with inoculation. Total F4/80-CD11c+ dendritic cells (DCs) maintained a relatively stable level, whereas conventional type 1 dendritic cells (cDC1) increased gradually from day 1 to day 28. There was a lower number of CD4+ and CD8+ T cells at day 1 and day 7, and they had similar results with a ceiling level at day 28. The testes displayed a higher level of CD3+ T cells but a lower frequency of macrophages, cDC2, and neutrophils at 28 days post-inoculation compared with the epididymis. In summary, our data indicates acute epididymo-orchitis could lead to long-term damage in the testes, which is characterized by CD3+ T cell (including CD4+ and CD8+ T cells)-mediated immune responses.

Tuberculosis epididmorchistis masquerading as a testicular malignancy in HIV positive patient: A case report and literature review.

Tuberculosis (TB) remains a significant health concern, with this study focusing on tuberculous epididymo-orchitis. Genitourinary TB (GUTB) diagnosis is difficult using conventional methods like acid-fast staining, culture, and PCR. A case study involves a 22-year-old HIV-diagnosed male with a painless progressive testicular swelling. A radical orchidectomy revealed isolated tuberculosis epididymo-orchitis. The study emphasizes considering this diagnosis for testicular masses, recognizing the diagnostic complexity and potential need for surgical intervention in cases of ambiguity.

Fever of unknown origin revealing testicular nocardiosis: a case report and literature review.

BACKGROUND: Nocardia is an ubiquitous soil organism. As an opportunistic pathogen, inhalation and skin inoculation are the most common routes of infection. Lungs and skin are the most frequent sites of nocardiosis. Testis is a highly unusual location for nocardiosis. CASE PRESENTATION: We report the case of an immunocompromised 75-year-old-man admitted for fever of unknown origin. He presented with skin lesions after gardening and was first suspected of Mediterranean spotted fever, but he did not respond to doxycycline. Then, physical examination revealed new left scrotal swelling that was compatible with a diagnosis of epididymo-orchitis. The patient's condition did not improve despite empirical antibiotic treatment with the onset of necrotic scrotal abscesses requiring surgery. Nocardia brasiliensis yielded from the removed testis culture. High-dose trimethoprim-sulfamethoxazole and ceftriaxone were started. Multiple micro-abscesses were found in the brain and spinal cord on imaging studies. After 6 weeks of dual antibiotic therapy for disseminated nocardiosis, slight regression of the brain abscesses was observed. The patient was discharged after a 6-month course of antibiotics and remained relapse-free at that time of writing these lines. Trimethoprim-sulfamethoxazole alone is meant to be pursued for 6 months thereafter. We undertook a literature review on previously reported cases of genitourinary and urological nocardiosis; to date, only 36 cases have been published with predominately involvement of kidney, prostate and testis. CONCLUSIONS: To the best of our knowledge, this is the first case of Nocardia brasiliensis simultaneously infecting skin, testis, brain and spinal cord in an immunocompromised patient. Knowledge on uncommon forms of nocardiosis remains scarce. This case report highlights the difficulty of diagnosing atypical nocardiosis and the importance of prompt bacteriological sampling in case of empirical antibiotics failure.

Multimodal ultrasound diagnosis of epididymo-orchitis with secondary testicular infarction: A case report.

We report a case of a 48-year-old man with testicular infarction caused by epididymo-orchitis (EO). Multimodal ultrasound showed extensive necrosis of the testis, and the patient underwent right orchiectomy. Postoperative pathology confirmed extensive necrosis of the testis. After 3 months of follow-up, the examination of scrotal ultrasound showed that the left testis and epididymis had no obvious abnormality.

Necrotizing granulomatous epididymo-orchitis post intravesical BCG administration after brachytherapy for prostate cancer.

Urothelial carcinoma of the bladder remains a challenging disease to treat. Intravesical instillation of BCG has demonstrated tremendous efficacy in preventing recurrence. BCG related necrotizing granulomatous epididymo-orchitis is rare and has not been previously linked to brachytherapy for adenocarcinoma of the prostate. We hypothesize that prior brachytherapy has a deleterious effect on the verumontanum that can result in retrograde transmission of BCG particles leading to granulomatous epididymo-orchitis. This is the first case report of necrotizing granulomatous epididymo-orchitis related to BCG in a patient status post brachytherapy for adenocarcinoma of the prostate.

Neonatal epididymo-orchitis with pyocele mimicking testicular torsion: A case report.

We report a case of epididymo-orchitis (EO) in a 12-day-old Saudi boy. The neonate, initially diagnosed with hydrocele post-delivery, presented with left scrotal swelling. Doppler ultrasound revealed normal testicles but an enlarged, echogenic left epididymis with pyocele. Despite initial therapy with amoxicillin and cefotaxime, a repeated ultrasound indicated compromised testicular vascularity, necessitating emergency surgical exploration. This revealed purulent discharge and inflammation, with Escherichia coli as a causative agent. Post-surgery, the patient showed significant improvement and was discharged in good condition after a ten-day of hospitalization. The study emphasizes the significance of including EO in the possible diagnoses for neonatal scrotal swelling.

Novel presentation of Raoultella planticola-induced epididymo-orchitis post gastroenteritis.

This report documents the first case of Raoultella planticola epididymo-orchitis following campylobacter gastroenteritis in a 76-year-old male. Highlighting R. planticola's expanded pathogenic potential beyond common urinary tract infections, this case emphasizes its clinical significance in atypical genitourinary presentations, particularly in individuals with pre-existing conditions like diabetes mellitus and renal failure. Despite intrinsic ampicillin resistance, targeted ciprofloxacin treatment proved effective. This case underscores the necessity for broad diagnostic considerations and tailored antibiotic therapy in managing complex infections, advocating for increased awareness of emerging resistant uropathogens in clinical practice.

Haemophilus Influenzae Epididymo-Orchitis and Bacteraemia in an Immunocompetent Patient.

Background: Epididymitis is a common cause of scrotal pain in adults, with coliform bacteria being the most common isolated organisms in patients older than 35. Case presentation: A 51-year-old healthy patient presented with scrotal pain and swelling, and was found to have epididymo-orchitis and bacteraemia caused by Haemophilus influenzae, which has not previously been reported as a cause of epididymo-orchitis and bacteraemia in immunocompetent patients. Discussion: Diagnostic studies can help confirm the diagnosis and detect the causative pathogen. In all suspected cases, a urinalysis, urine culture and a urine or urethral swab for nucleic acid amplification tests (NAATs) for Neisseria gonorrhoeae and Chlamydia trachomatis should be performed. Colour Doppler ultrasonography often shows an enlarged thickened epididymis with increased Doppler wave pulsation in epididymitis. H. influenzae are pleomorphic gram-negative rods that commonly colonise the human respiratory tract and are associated with a number of clinical conditions. H. influenzae has been reported as a cause of epididymo-orchitis in prepubertal boys, and in few cases were associated with positive blood cultures. In adults, H. influenzae has been isolated before from urine samples or urethral swabs in patients with epididymitis or epididymo-orchitis. Conclusion: This case highlights the possibility of H. influenzae causing epididymo-orchitis and bacteraemia in immunocompetent patients. Healthcare providers should consider H. influenzae in the differential diagnosis of epididymitis and epididymo-orchitis in both immunocompetent and immunocompromised patients. LEARNING POINTS: H. influenzae can cause epididymo-orchitis and bacteraemia in immunocompetent patients. This has not been previously reported.H. influenzae should be considered in the differential diagnosis of epididymitis and epididymo-orchitis in both immunocompromised and immunocompetent patients.Healthcare providers should be aware of the increasing incidence of epididymitis and epididymo-orchitis caused by non-coliform bacteria in patients older than 35 years, especially in immunocompromised patients.

Paediatric acute epididymo-orchitis temporally related to SARS-CoV-2 infection: A case series and review of the literature.

INTRODUCTION: Acute epididymo-orchitis (AEO) is becoming an increasingly common differential diagnosis in children with acute scrotal pain. It has been noted in adult men that SARS-CoV-2 has a propensity for involving the testis and epididymis, affecting sperm and testosterone production. Our literature search revealed only one case report of COVID-19 presenting with epididymo-orchitis in a child. We present three more children who presented with AEO, all recovering from PCR-confirmed SARS-CoV-2 infection. This article reviews the post-inflammatory aetiology of paediatric epididymo-orchitis, and the propensity SARS-CoV-2 has for the testis. PATIENTS AND METHODS: Two pre-pubertal ten-year-old patients presented to the emergency department with a 48-h history of gradual onset unilateral scrotal pain and increasing erythema of the ipsilateral scrotal skin. One fifteen-year-old boy was referred for ongoing symptoms four days following a diagnosis of AEO made by his General Practitioner. On further questioning, all three had PCR-confirmed COVID infection two weeks prior to the onset of their scrotal symptoms and had just ended their isolation period. A literature search was then performed using the keywords SARS-CoV-2, testes and paediatric acute epididymo-orchitis. DISCUSSION: The SARS-Cov-2 virus has a propensity for affecting the testis and epididymis. This puts patients at increased risk of acute epididymo-orchitis during COVID infections. The inflammation induced by the virus appears to affect the cells responsible for testosterone production and sperm quality. However, there is no evidence that viral transmission can happen via semen. CONCLUSION: SARS-Cov-2 infection can lead to acute epididymo-orchitis. Knowledge of this is clinically significant, firstly to avoid unnecessary surgical intervention due to a mistaken diagnosis of testicular torsion and secondly, due to the potential of the virus to affect sperm quality and testosterone production.

Role of High-Resolution Ultrasonography With Colour and Duplex Doppler in the Evaluation of Acute Scrotal Diseases.

Introduction The term 'acute scrotum' denotes the sudden initiation of pain in the scrotal region. Acute scrotum is a frequent medical condition in children and adults. Ultrasound facilitates precise diagnosis and differentiation of numerous causes of acute scrotum. The objective of our research was to assess the utility of ultrasonography in the identification and prevalence determination of causes of acute scrotum. Materials and methods Patients with acute scrotal pain referred to the Department of Radiodiagnosis at Great Eastern Medical School & Hospital (GEMS), Srikakulam, India, were added in the research. This is a prospective observational study. High-frequency linear transducer (4-15 MHz) was used for imaging. Grey scale, colour and duplex Doppler were performed routinely. The ultimate diagnosis was established by considering the clinical results, follow-up observations, intraoperative observations and, when accessible, histopathological analysis. For the statistical analysis, IBM SPSS Statistics for Windows, version 22 (released 2013; IBM Corp., Armonk, New York, United States). was used. Descriptive analysis was conducted. The Kendall rank correlation coefficient was used to evaluate the non-parametric association between side and torsion. Results A total of 120 patients were included for statistical analysis. Inflammatory pathology was the most common cause of acute scrotum, followed by testicular torsion and torsion of testicular appendage. Testicular torsion and side of pain did not show a significant association. Conclusion High-resolution ultrasonography with colour and duplex Doppler sonography is an excellent imaging modality exhibiting exceptional sensitivity and specificity for the accurate diagnosis of acute scrotal diseases. Inflammatory pathology was the most common cause of acute scrotum, followed by testicular torsion and torsion of the testicular appendage.

Unilateral Testicular Infarction a Very Rare Complication of Genital Tuberculosis: A Case Report and Literature Review.

Background: Genitourinary tuberculosis is the second most common form of extrapulmonary tuberculosis in developing countries. Isolated genital TB is rare, but testicular infarction is an unusual complication of delayed management, in which surgical intervention is warranted. Case Presentation: A 29-year-old male non-smoker presents with painful left scrotal pain of 21 days. Initially managed with intravenous antibiotics, the disease progressed and resulted in testicular infarction. Left orchiectomy was performed, and the specimen was sent for histopathological examination, which revealed features consistent with a testicular tuberculous abscess. Conclusion: Tuberculous epididymo-orchitis (TBEO) with testicular infarction was unusual. It is prudent to consider this in patients presenting with long-standing urinary symptoms, particularly in those unresponsive to the initial antibiotic therapy. It requires a high index of suspicion, especially in TB endemic areas.

Testicular involvement of Brucellosis: A 10-year, multicentre study.

INTRODUCTION: The genito-urinary system is one of the most common areas of involvement in brucellosis. To present the epidemiological, clinical, and laboratory characteristics of patients with testicular involvement associated with brucellosis, together with the diagnostic and therapeutic approaches. METHODOLOGY: Patients followed up for brucellosis-related testicular involvement between January 2012 and November 2022 were included in the study. Brucellosis is defined as the production of Brucella spp. in cultures, or clinical symptoms together with the serum standard tube agglutination test titer of ≥ 1/160. Inflammation in scrotal Doppler ultrasonography was based on testicular involvement. RESULTS: A retrospective evaluation was made of the data of 194 patients with brucellosis-related testicular involvement. The rate of determination of testicular involvement in brucellosis was 2.57%. The most affected patients were determined in the 16-30 years age range. On presentation, brucellosis was in the acute stage in 83.7% of patients. The most common symptoms on presentation were swelling and/or pain in the testes (86.6%). In the patients where a spermiogram could be performed, oligospermia was determined in 41.7%, and aspermia in 8.3%. When the testicular involvement of brucellosis was evaluated, epididymo-orchitis was present at the rate of 55.7%, epididymitis at 27.3%, and testis abscess at 5.1%. CONCLUSIONS: Although epididymo-orchitis was the most frequently determined form of involvement in this study, there was also seen to be a significant number of patients presenting with epididymitis. Male patients presented with the clinical status of brucellosis should be questioned about swelling and pain in the testes to avoid overlooking testicular involvement.

Human Tularemia Epididymo-Orchitis Caused by Francisella tularensis Subspecies holartica, Austria.

A previously healthy man in Austria had tularemia epididymo-orchitis develop, leading to unilateral orchiectomy. Francisella tularensis subspecies holartica was detected by 16S rRNA gene sequencing analysis of inflamed granulomatous testicular tissue. Clinicians should suspect F. tularensis as a rare etiologic microorganism in epididymo-orchitis patients with relevant risk factors.

Brucellar testicular abscess: The 17th case report and review of literature.

Brucellosis is an endemic zoonotic disease caused by intracellular gram-negative coccobacilli called Brucella. This infectious disease may implicate many farm animals and is transmissible to exposed humans. Brucellosis is potentially life-threatening and may lead to granulomatous multi-organ involvement with tendency to chronicity and recurrence. The treatment of brucellosis requires combined and protracted antimicrobial therapies to eliminate the disease and to avoid its relapse. Genitourinary brucellosis is common among infected humans in endemic areas and is considered the second-most affected focal site, which commonly manifests as epididymo-orchitis. Testicular abscess, however, is an extremely rare complication of brucellosis. To the best of our knowledge, in the literature, there are to date only 16 previously published case reports, including 22 patients of brucellar testicular abscesses, emphasizing the extreme rarity of this condition. Most of these cases harbored small abscesses, which were treated conservatively using antibiotics therapy only, or with added drainage of the abscesses. Larger abscesses were reported to necessitate orchiectomy. In some cases, the abscesses were mimicking tumors, and surgeries for orchiectomy were done accordingly. A summary of the previously reported cases in the literature is presented. Here, we present the 17th case report of a 34-year-old man with a right-side huge multilocular brucellar testicular abscess apparently replacing the entire testicle, who was successfully treated with organ-sparing management by incision-drainage of the large abscess with antibiotics, to eventually preserve his testis. In conclusion, brucellosis should be considered among the differential diagnoses of any testicular swelling, especially in endemic areas. Drainage of brucellar testicular abscess with appropriate medical treatment is feasible and may preserve the testicle, even with large abscess apparently replacing the entire testicle.

Testicular ischemia associated with IgA vasculitis in a child: a case report and literature review.

Testicular necrosis is a rare and severe complication of immunoglobulin A (IgA) vasculitis (IgAV). Herein, We report a case of a 10-year-old boy who was admitted to the hospital due to skin purpura and intermittent abdominal pain for 10 days and bilateral testicular pain for 2 days. Scrotal ultrasonography indicated right testicle ischemia, right epididymo-orchitis, and bilateral hydrocele of the testis. Scrotal surgical exploration revealed significant swelling and darkening of the right testicle. Conservative treatment led to improvement in his condition, and he was discharged. During 3 months of follow-up, there was no recurrence of skin purpura or pain, and the urine tests were normal. Color ultrasound indicated only partial blood flow signal to the right testicle tissue, which was slightly smaller than the left testicle. This case highlights the need for continuous attention from clinicians to the signs and symptoms of the reproductive system during the diagnosis and treatment of IgAV. Continuous monitoring with ultrasound can aid in early detection, diagnosis, and treatment of reproductive system lesions of IgA vasculitis.

An Overview of Emphysematous Epididymo-Orchitis: A Systematic Review of Case Reports.

Emphysematous epididymo-orchitis (EEO) is a rare but serious condition that involves the presence of gas within the tissues of the testicle and/or the epididymis. It is a medical emergency that can be life-threatening if left untreated. Management of this condition may involve a combination of antibiotics, surgical drainage, and supportive care. In March 2023, A systematic review of case reports was conducted to identify and examine cases of EEO. We used PubMed, ScienceDirect, and Google Scholar for a methodical search. Only seven out of 136 studies met our criteria for this review of case reports. However, this review discusses symptom presentation, imaging findings, complications, and possible management of EEO.

Emphysematous Epididymo-Orchitis: A Rare Case Report.

Emphysematous epididymo-orchitis is a rare and potentially fatal infection marked by the presence of gas in the epididymis and testicular tissue. Here, we describe the case of a 49-year-old male with a known past medical history of diabetes and hypertension who presented with right inguinoscrotal swelling and severe tenderness. An urgent scrotal ultrasound was obtained and revealed a fluid-filled avascular mass. Moreover, the non-contrast CT scan showed a mixture of air and fluid density in the right epididymis, perineum, and spermatic cord course. The medical team confirmed the diagnosis of emphysematous epididymo-orchitis. The patient refused the management plan at first, but later came back and accepted the procedure. A right orchidectomy with spermatic cord removal was performed without complications.

Early predictors of Brucella epididymo-orchitis.

Introduction: Epididymo-orchitis (EO) is a common urological condition. In endemic areas, EO may be the presenting picture of brucellosis. Early suspicion and proper diagnosis is necessary for patient recovery. Objective: The aim of our study is to identify early predictors of Brucella EO. Patients and Methods: We retrospectively collected the data of all patients who were treated at the Urology Unit, Farwaniya Hospital, with acute EO above the age of 12 years between April 2017 and February 2019. Data from electronic and hardcopy files were gathered and analyzed. The diagnosis of acute EO was based on clinical, laboratory, and radiological findings. A total of 120 patients under the diagnosis of EO, epididymitis, and orchitis were reviewed. Thirty-one patients were tested for Brucella based on the history of animal contact, ingestion of unpasteurized dairy products, or persistent fever for more than 48 h. of those patients, 11 tested positive for Brucella orchitis. Results: A comparison between Brucella-positive and Brucella-negative patients regarding age, presence of fever, complete blood count (CBC) parameters, pyuria, and abscess formation was made. In the Brucella group, 72% of the patients had a history of animal contact compared to 33% in non-Brucella group (P = 0.006). When comparing CBC parameters in the two groups, Brucella group had statistically significant lower total leukocytic count and neutrophil count (mean ± standard deviation [SD]) 13.07 ± 4.22, 6.4 ± 9.98 versus Brucella negative group 17.35 ± 5.28, 7.8 ± 10.53, and P values were 0.037 and 0.004, respectively. Brucella group showed lymphocytosis (mean ± SD) 25.95 ± 9.78 versus non-Brucella group 13.22 ± 8.05 and P < 0.01. Conclusion: Brucella orchitis constituted 9% of the orchitis patients treated in our hospital. Patients with a history of animal contact, EO with lymphocytosis, and relative neutropenia should raise the suspicion for Brucella orchitis in endemic areas.

A rare presentation of visceral leishmaniasis and epididymo-orchitis in a patient with chronic granulomatous disease.

Visceral leishmaniasis (VL) has rarely been reported in patients with chronic granulomatous disease (CGD), despite the fact that they seem more susceptible to intracellular infection. We describe a rare presentation of VL and epididymo-orchitis in a patient with CGD, which has not been seen previously in the literature following inflammatory syndrome.

Orquiepididimitis por Salmonella spp en un lactante bajo los tres meses de edad / Salmonella spp epididymo-orchitis in a infant under three months-old

El compromiso genitourinario en una infección causada por Salmonella spp es poco frecuente, especialmente en niños. Se presenta un paciente de 40 días de vida que presentó una orquiepididimitis por Salmonella entérica serotipo Newport, con documentación microbiológica en hemocultivos, cultivo de secreción escrotal y coprocultivo. No presentó compromiso del sistema nervioso central. Un tratamiento médico y quirúrgico tempranos permitieron la evolución favorable del paciente.

Genitourinary involvement in a Salmonella spp infection is rare, especially in pediatric patients. A 40-day-old patient who presented an orchiepididymitis due to Salmonella enterica Serotype Newport is reported, with microbiological documentation in blood cultures, culture of scrotal purulent material and stool culture. There was no involvement of the central nervous system. Early medical and surgical treatment allowed the favorable evolution of the patient.
