[Acute scrotum in children]. / ABC om Akut skrotum hos barn.

Acute scrotum in a child is common, and the main underlying conditions are torsion of intrascrotal appendages, epididymitis, testicular torsion and idiopathic scrotal edema. The main diagnostic aim is to confirm or rule out testicular torsion, since this may lead to irreversible ischemia within hours. The diagnostics can be difficult, especially in prepubertal boys, but consist of a thorough history and clinical examination, the use of a clinical prediction score, and sometimes ultrasound with doppler. However, none of these tools can with completely accuracy rule out a testicular torsion, and uncertainty should prompt an acute scrotal exploration. The treatment of a testicular torsion is detorsion and bilateral orchidopexy, or unilateral orchidectomy in case of a completely necrotic testicle. Treatment of the other underlying conditions is often only symptomatic, and follow-up is often not required.

[Traditional Chinese medicinal compress combined with herbal fumigation for acute epididymitis: A clinical observation].

OBJECTIVE: To observe the clinical efficacy of traditional Chinese medicinal (TCM) compress combined with herbal fumigation in the treatment of acute epididymitis. METHODS: This study included 74 cases of acute epididymitis treated in our hospital from December 2021 to December 2023. Using the single blind and random number methods, we divided the patients into a trial (n = 37) and a control group (n = 37). On the basis of routine medication with antibiotics, we treated the patients in the trial group by TCM compress combined with herbal fumigation and those in the control group by dyed pure water compress combined with herbal fumigation. At 3, 7 and 14 days of treatment, we obtained the pain scores and maximum epididymal diameters from the patients and compared them between the two groups before and after treatment. RESULTS: There were no statistically significant differences between the control and trial groups in the baseline pain scores (6.79 vs 6.85, P>0.05) and maximum epididymal diameters of the patients (ï¼»1.61 ± 0.39ï¼½ vs ï¼»1.59 ± 0.42ï¼½ cm, P>0.05) or in the pain scores after 3 days of treatment (4.63 ± 0.95 vs 4.45 ± 1.87, P>0.05). Compared with the controls, the patients of the trial group showed significantly lower pain scores (3.78 ±1.03 vs 1.02±0.36, P<0.05) and a higher overall effectiveness rate (75.68% vs 91.89%, P<0.05) at 7 days, and markedly shorter maximum epididymal diameters at 3 days (ï¼»1.45 ± 0.38ï¼½ vs ï¼»1.23 ± 0.72ï¼½ cm, P<0.05) and 7 days (ï¼»1.21 ± 0.29ï¼½ vs ï¼»0.98 ± 0.15ï¼½ cm, P<0.05). No statistically significant differences were observed between the control and trial groups in the pain scores (0.79 ± 1.12 vs 0.67 ± 0.86, P>0.05), maximum epididymal diameters (ï¼»0.94 ± 0.33ï¼½ vs ï¼»0.92 ± 0.21ï¼½ cm, P>0.05) or overall effectiveness rate (91.89% vs 97.30%, P>0.05) after 14 days of treatment. CONCLUSION: On the basis of routine medication with antibiotics, TCM compress combined with herbal fumigation can effectively relieve pain, reduce local swelling, accelerate recovery and shorten the course of treatment in patients with acute epididymitis, and is therefore worthy of clinical promotion and application.

Pulmonary abscess secondary to epididymitis caused by extended spectrum ß-lactamase-producing hypervirulent Klebsiella pneumoniae: a case report.

BACKGROUND: Pulmonary abscesses resulting from epididymitis caused by extended spectrum ß-lactamase-producing hypervirulent Klebsiella pneumoniae (ESBL-hvKp) in a nondiabetic patient are extremely uncommon. The infection caused by this disseminated drug-resistant bacteria, which is generally considered an intractable case, poses a potential challenge in clinical practice. CASE PRESENTATION: In this case report, we present the clinical course of a 71-year-old male patient with epididymitis, who subsequently developed cough and dyspnea following anti-infection treatment. Imaging examinations revealed severe pneumonia and pulmonary abscess. The infection of ESBL-hvKp in the epididymis led to bacteremia and subsequent lung lesions. Due to poor response to anti-infection therapy, the patient required an extended duration of anti-infection treatment and ultimately chosed to discontinue treatment. CONCLUSIONS: Acute epididymitis caused by ESBL-hvKP infection can result in the spread of the infection through the bloodstream, leading to severe pneumonia and lung abscess. Given the critical condition of the patient, even with active anti-infection treatment, there is a risk of treatment failure or potentially fatal outcomes.

A new nomogram based on ultrasound and clinical features for distinguishing epididymal tuberculosis and nontuberculous epididymitis.

Using ultrasound findings and clinical characteristics, we constructed and validated a new nomogram for distinguishing epididymal tuberculosis from nontuberculous epididymitis, both of which share similar symptoms. We retrospectively examined data of patients with epididymal tuberculosis and nontuberculous epididymitis hospitalized between January 1, 2013, and March 31, 2023. Eligible patients were randomly assigned to derivation and validation cohorts (ratio, 7:3). We drew a nomogram to construct a diagnostic model through multivariate logistic regression and visualize the model. We used concordance index, calibration plots, and decision curve analysis to assess the discrimination, calibration, and clinical usefulness of the nomogram, respectively. In this study, 136 participants had epididymal tuberculosis and 79 had nontuberculous epididymitis. Five variables-C-reactive protein level, elevated scrotal skin temperature, nodular lesion, chronic infection, and scrotal skin ulceration-were significant and used to construct the nomogram. Concordance indices of the derivation and validation cohorts were 0.95 and 0.96, respectively (95% confidence intervals, 0.91-0.98 and 0.92-1.00, respectively). Decision curve analysis of this nomogram revealed that it helped differentiate epididymal tuberculosis from nontuberculous epididymitis. This nomogram may help clinicians distinguish between epididymal tuberculosis and nontuberculous epididymitis, thereby increasing diagnosis accuracy.

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.

Influence of preoperative antituberculosis chemotherapy duration on perioperative complications in patients treated with epididymectomy for epididymal tuberculosis.

OBJECTIVES: We aimed to investigate the influence of preoperative antituberculosis chemotherapy duration on perioperative epididymectomy complications in patients with epididymal tuberculosis (ETB). METHODS: This retrospective study examined patients with ETB between January 1, 2013, and March 31, 2023, who underwent unilateral epididymectomy at our hospital. We selected preoperative antituberculosis chemotherapy duration of 2, 4, and 8 weeks as the cutoffs for this study, to explore whether there are differences in the incidence of intraoperative and 30-day postoperative complications among the patients with different preoperative antituberculosis chemotherapy durations. Intraoperative complications were graded according to the Satava classification, and 30-day postoperative complications were defined according to the Clavien-Dindo classification. The study groups were compared using the unpaired t-test, Wilcoxon rank-sum test, Pearson's chi-square test, or Fisher's exact test, as appropriate. RESULTS: Overall, 155 patients were included. Statistical analysis revealed that there were no significant differences in the incidence of intraoperative and 30-day postoperative complications between patients with shorter preoperative antituberculosis chemotherapy duration and those with longer preoperative antituberculosis chemotherapy duration. CONCLUSIONS: In patients with ETB, preoperative antituberculosis chemotherapy duration did not significantly affect the incidence of perioperative complications after epididymectomy.

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.

Association between left-sided varicocele and epididymo-orchitis with sonographic findings.

OBJECTIVE: The aim of this study was to investigate the relationship between left-sided varicocele and epididymitis or epididymo-orchitis. MATERIALS AND METHODS: The study included 72 patients with left side epididymitis (EP) or epididymo-orchitis (EPO) (Group 1) and a control group of 72 patients without EP or EPO (Group 2). Those with right EP-EPO were excluded due to possible other underlying retroperitoneal pathologies causing varicocele. Groups were evaluated for presence of left side varicocele, varicocele grade and pampiniform plexus vein diameter. RESULTS: The average age was 38 ± 8.4 years (range, 18-50 years) in Group 1, and 36 ± 9.1 years (range, 16-47 years) in Group 2. Varicocele was significantly more common in patients with EP or EPO (p < 0.001). The rate of varicocele was 66.7% (48/72) in Group 1, and 22.3% (16/72) in Group 2. The median grade of varicocele was 2 in Group 1, and 0 in Group 2. Pampiniform plexus vein diameters were found to be significantly larger in patients with EP or EPO compare to patients without EP and EPO. The median vein diameter was 3.3 mm with the 25th and 75th percentiles at 2.7 and 3.8 mm, and was 1.9 mm with the 25th and 75th percentiles at 1.7 and 2.3 mm, respectively (p < 0.001). CONCLUSIONS: Left-sided varicocele was significantly more common in patients with EP or EPO and it is an important cause for the development of EP/EPO because of chronic venous stasis.

The challenges in diagnosing isolated epididymal tuberculosis (TB) in an adolescent male: a case report.

BACKGROUND: Genitourinary tuberculosis (GUTB) is a common form of extrapulmonary TB (EPTB) in children. An example of GUTB is epididymal TB, which usually presents unspecific chronic clinical manifestations. Definitive diagnosis can be conducted based on bacteriologic confirmation and histopathologic results, but this is challenging due to the paucibacillary nature of EPTB. Therefore, we reported the challenges in diagnosing isolated epididymal TB in an adolescent male. CASE PRESENTATION: A 16-year-old male presented to respirology clinic with painful swelling of the left scrotum for 3 months before visiting to the hospital. The symptoms were associated with persistent coughing for 2 months, and physical examination of the left scrotum showed swelling accompanied by cardinal signs. A palpable hard mass was found on the left scrotum, with firm borders, measuring 7 × 4 cm. Laboratory examination and tumor markers were within normal limits, although leukocyturia was found, and the urine culture was negative. Genital ultrasound (US) showed epididymitis sinistra with septal hydrocele, while magnetic resonance imaging (MRI) indicated inhomogeneous left epididymitis with bilateral inguinal lymph node enlargement. Although TB evaluation presented a negative purified protein derivative (PPD) test and bacteriologic examination, chest X-ray (CXR) showed perihilar lymphadenopathy. Based on the clinical and radiologic results suggesting TB, the patient was diagnosed with isolated epididymal TB and received quadruple antituberculosis therapy (ATT) for 6 months. After treatment, the left testicle size started to shrink and was equal to the right testicle, also, there were no signs of inflammation, the body weight increased by 5 kg, and cough disappeared. Sperm analysis at the end of treatment indicated teratozoospermia, which was subsequently treated by the urologic surgery department. CONCLUSIONS: Biopsy and bacteriologic confirmation for TB epididymitis were challenging to perform in the clinical setting. Epididymal TB should be considered in adolescent males with complaints of chronic scrotal swelling and pain. Clinical judgment based on history taking, physical examination, and radiologic features supporting TB features could be helpful in accurate and fast diagnosis for favorable outcome.

Regional modulation of toll-like receptor signaling pathway genes in acute epididymitis in mice.

BACKGROUND: Region-specific immune environments in the epididymis influence the immune responses to uropathogenic Escherichia coli (UPEC) infection, a relevant cause of epididymitis in men. Toll-like receptors (TLRs) are essential to orchestrate immune responses against bacterial infections. The epididymis displays region-specific inflammatory responses to bacterial-derived TLR agonists, such as lipopolysaccharide (LPS; TLR4 agonist) and lipoteichoic acid (LTA; TLR2/TLR6 agonist), suggesting that TLR-associated signaling pathways could influence the magnitude of inflammatory responses in epididymitis. OBJECTIVES: To investigate the expression and regulation of key genes associated with TLR4 and TLR2/TLR6 signaling pathways during epididymitis induced by UPEC, LPS, and LTA in mice. MATERIAL AND METHODS: Epididymitis was induced in mice using UPEC, ultrapure LPS, or LTA, injected into the interstitial space of the initial segment or the lumen of the vas deferens close to the cauda epididymidis. Samples were harvested after 1, 5, and 10 days for UPEC-treated animals and 6 and 24 h for LPS-/LTA-treated animals. Ex vivo epididymitis was induced by incubating epididymal regions from naive mice with LPS or LTA. RT-qPCR and Western blot assays were conducted. RESULTS: UPEC infection up-regulated Tlr2, Tlr4, and Tlr6 transcripts and their associated signaling molecules Cd14, Ticam1, and Traf6 in the cauda epididymidis but not in the initial segment. In these epididymal regions, LPS and LTA differentially modulated Tlr2, Tlr4, Tlr6, Cd14, Myd88, Ticam1, Traf3, and Traf6 expression levels. NFKB and AP1 activation was required for LPS- and LTA-induced up-regulation of TLR-associated signaling transcripts in the cauda epididymidis and initial segment, respectively. CONCLUSION: The dynamic modulation of TLR4 and TLR2/TLR6 signaling pathways gene expression during epididymitis indicates bacterial-derived antigens elicit an increased tissue sensitivity to combat microbial infection in a spatial manner in the epididymis. Differential activation of TLR-associated signaling pathways may contribute to fine-tuning inflammatory responses along the epididymis.

Evaluating ChatGPT ability to answer urinary tract Infection-Related questions.

INTRODUCTION: For the first time, the accuracy and proficiency of ChatGPT answers on urogenital tract infection (UTIs) were evaluated. METHODS: The study aimed to create two lists of questions: frequently asked questions (FAQs, public-based inquiries) on relevant topics, and questions based on guideline information (guideline-based inquiries). ChatGPT responses to FAQs and scientific questions were scored by two urologists and an infectious disease specialist. Quality and reliability of all ChatGPT answers were checked using the Global Quality Score (GQS). The reproducibility of ChatGPT answers was analyzed by asking each question twice. RESULTS: All in all, 96.2 % of FAQs (75/78 inquiries) related to UTIs were correctly and adequately answered by ChatGPT, and scored GQS 5. None of the ChatGPT answers were classified as GQS 2 and GQS 1. Moreover, FAQs about cystitis, urethritis, and epididymo-orchitis were answered by ChatGPT with 100 % accuracy (GQS 5). ChatGPT answers for EAU urological infections guidelines showed that 61 (89.7 %), 5 (7.4 %), and 2 (2.9 %) ChatGPT responses were scored GQS 5, GQS 4, and GQS 3, respectively. None of the ChatGPT responses for EAU urological infections guidelines were categorized as GQS 2 and GQS 1. Comparison of mean GQS values of ChatGPT answers for FAQs and EAU urological guideline questions showed that ChatGPT was similarly able to respond to both question groups (p = 0.168). The ChatGPT response reproducibility rate was highest for the FAQ subgroups of cystitis, urethritis, and epididymo-orchitis (100 % for each subgroup). CONCLUSION: The present study showed that ChatGPT gave accurate and satisfactory answers for both public-based inquiries, and EAU urological infection guideline-based questions. Reproducibility of ChatGPT answers exceeded 90% for both FAQs and scientific questions.

Epididymitis with Pasteurella multocida isolated from two male Japanese Black beef calves.

Two male Japanese Black calves developed an enlarged scrotum and testis. Orchiectomy was performed and pus was collected during surgery. After removal of the testis, bacteriological and histopathological examinations were conducted to investigate the cause and confirm the diagnosis. Based on the results obtained, both cases were diagnosed with epididymitis caused by an infection with Pasteurella multocida. This is the first study to show that P. multocida causes epididymitis in male calves. Further studies are required to clarify the details underlying the infection of calves with P. multocida.

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.

Complications of different methods of urological management in people with neurogenic bladder secondary to spinal cord injury.

OBJECTIVE: To investigate the association between multiple types of urological management and urological complications in patients with spinal cord injury (SCI). DESIGN: A retrospective cohort study. SETTING: Single medical center. METHODS: Medical records of SCI patients with regular follow-up of more than two years were reviewed. Urological management was classified into five groups: indwelling urethral catheter (IUC), clean intermittent catheterization (CIC), reflex voiding, suprapubic catheter (SPC), and self-voiding. We analyzed the incidence of urinary tract infection (UTI), epididymitis, hydronephrosis, and renal stone across the different urological-management groups. RESULTS: Of 207 individuals with SCI, the most common management type was self-voiding (n = 65, 31%) followed by CIC (n = 47, 23%). The IUC and SPC groups included more people with complete SCI than the other management groups. Compared with the IUC group, the SPC and self-voiding groups had lower risks of developing UTI (relative risk [RR] = 0.76, 95% CI, 0.59-0.97 and RR = 0.39, 95% CI, 0.28-0.55, respectively). The SPC group tended to have a lower risk of epididymitis than the IUC group (RR = 0.55, 95% CI, 0.18-1.63). CONCLUSION: Long-term IUC use was associated with a higher incidence of UTI in people with SCI. As compared to those with IUC, a lower risk of UTI was found in persons with SPC. These findings may have implications for shared clinical decision-making.

Acute cytomegalovirus proctitis and epididymitis acquired via sexual transmission in an immunocompetent patient: a case report.

BACKGROUND: We present a case report of an immunocompetent host with presumed sexually transmitted cytomegalovirus proctitis and epididymitis, where there currently is a sparsity of published data. CASE PRESENTATION: A 21-year-old previously healthy Caucasian individual was admitted for severe rectal and testicular pain in the setting of proctitis and epididymitis. Serology and rectal pathology confirmed acute primary cytomegalovirus infection. CONCLUSIONS: This report details his diagnostic workup and highlights cytomegalovirus as a rare cause of sexually transmitted disease among immunocompetent persons.
