Testicular Torsion Following MMR Vaccination in an 18-Month-old Infant: A Case Report

Introduction: The measles, mumps, and rubella (MMR) vaccine is associated with known complications, such as salivary gland involvement and aseptic meningitis. Isolated reports of epididymal orchitis following MMR vaccination have also been reported, but no reported case of testicular torsion in infancy has been explicitly attributed to the MMR vaccine. Objective: Here, we report an 18-month-old male infant presented with a history of gradually worsening painful left scrotal swelling following a booster dose of MMR that finally led to orchiectomy with the diagnosis of testicular torsion. Case Presentation: An 18-month-old male infant presented with a one-day history of gradually worsening painful left scrotal swelling following a booster dose of MMR. No evidence of blood flow was detected in the left testicle in color Doppler sonography, which was compatible with testicular torsion. In surgical exploration, the left testicle seemed firm and dark in color. The spermatic cord vessels were thrombotic in appearance, and the testicular appendix seemed completely necrotic. The nonviable left testicle was removed. Conclusions: Although testicular torsion after MMR vaccination is rare, in the case of any pain, swelling, and redness of the scrotum, the patient should seek an urgent medical consultation. Physicians should be aware that testicular swelling after the MMR vaccine might not be just epididymal-orchitis but really a medical emergency.

SCROTAL HERNIATION AND STRANGULATION OF THE SMALL INTESTINE IN AN INTACT MALE 3-YEAR-OLD MIXED-BREED DOG

Importance: This case report describes a rare presentation of scrotal herniation and strangulation of the small intestine in a 3-year-old intact male mixed-breed dog. This condition is noteworthy due to its potential for severe complications and the scarcity of documented cases in the veterinary literature, contributing to the limited body of knowledge on scrotal hernias in dogs, especially those involving intestinal strangulation. Case Presentation: The dog presented with unilateral scrotal swelling, persistent vomiting and inappetence for 10 days. Physical examination revealed inflamed and tender scrotal regions, with the left side more prominently affected. Radiographic findings indicated dilated small intestines and increased radiopacity in the scrotal area. Surgical intervention revealed a swollen left testicle and a hemorrhagic loop of small intestines within the scrotum. A midline celiotomy was performed to resect and anastomose the devitalized intestinal segment, followed by herniorrhaphy. Conclusions and Relevance: The patient recovered uneventfully and resumed normal activities within a week post-surgery. This case highlights the clinical importance of timely diagnosis and surgical management of scrotal hernias in dogs to prevent life-threatening complications, underscoring the need for awareness of such presentations among veterinarians. The successful outcome in this case supports the efficacy of surgical intervention in similar scenarios, potentially guiding future clinical practices.

Liposarcoma del cordón espermático

Introduction: liposarcoma of the spermatic cord (LSC) is a rare condition and accounts for about 3 to 7% of all paratesticular sarcomas. A case is presented in an 80-year-old patient who consulted for a left inguinoscrotal painless swelling, that had been present for several years. Physical examination revealed a soft left hemiscrotal tumor that appeared not to be adherent to the testicle. Ultrasonography showed a solid, heterogeneous hyperschoic paratesticular mass with central calcifications and peripheral hypervascularity. During surgery, a diffuse lipomatous tumor was found in the spermatic cord on the superior pole of the left testicle, separated from it. Anatomopathological examination revealed a well-differentiated liposarcoma of the spermatic cord. Discussion: this neoplasm features a slow-growing palpable paratesticular mass. This site of occurrence is rare and represents 7 to 10% of all scrotal tumors. Imaging differentiation between LSC and benign lesions is sometimes challenging. Surgical treatment should include radical orchiectomy wide local excision, and spermatic cord and inguinal ring surrounding soft tissue resection. Conclusion: spermatic cord liposarcoma is a rare and unusual mesenchymal tumor and should be considered among the differential diagnoses of scrotal tumors.

Morphological and immunohistochemical characteristics of diffuse seminoma in horses: A case report.

The present study describes the morphological and immunohistochemical characteristics of a case of diffuse seminoma in a 16-year-old male mixed-breed horse. According to the owner, the animal's left testicle had been gradually increasing in size over a period of 2 months. On palpation, the testicle had a firm consistency, with no sensitivity to digital pressure, was adhered to the scrotum and measuring 16 cm × 8 cm. In the ultrasound examination, it presented a heterogeneous texture and areas of hypoechogenic echogenicity without visualization of the mediastinum. Therefore, the bilateral orchiectomy was performed. After the surgical procedure, it was found that the affected testicle presented a firm mass measuring 9 cm × 7 cm × 3.5 cm. Histologically, a multilobulated, non-encapsulated and invasive tumour mass was found, which replaced the seminiferous tubules, consisting of polygonal cells arranged in a mantle that varied from cohesive to loosely cohesive, supported by a scarce fibrous stroma. In the immunohistochemical examination, the neoplastic cells showed positive immunolabelling for OCT4 and C-KIT. In this report, the physical examination combined with the ultrasonographic examination were fundamental to the therapeutic management of the case, and the final diagnosis was made after histopathological and immunohistochemical tests.

Proanthocyanidin alleviates testicular torsion/detorsion-induced ischemia/reperfusion injury in rats

Testicular torsion is an urological emergency and can lead to ischemia damage and testicular loss if not diagnosed in time. Proanthocyanidin is reported to have anti-inflammatory and antioxidant properties. The current study aimed to examine the possible effects of proanthocyanidin (P) on the testis in torsion/detorsion (T/D)-induced testicular ischemia/reperfusion (I/R) injury in rats. Forty rats were divided into four groups (n=10 for each): sham-operated (sham), I/R, I/R + P100 (100 mg/kg, 30 min before torsion), and I/R + P200 (200 mg/kg, 30 min before torsion). Testicular T/D was performed on the left testicle by 3 hours of torsion at 720° clockwise, followed by 3 hours of detorsion. In the I/R group, an increase in malondialdehyde (MDA) levels and a decrease in glutathione (GSH), vitamin C (Vit C), glutathione peroxidase (GPx), glucose-6-phosphate dehydrogenase (G6PD) values were determined compared to the sham group (p<0.001). Moreover, an increase in the expression of cleaved caspase-3 and Bcl2-associated X protein (Bax), a decrease in the expression of B-cell lymphoma 2 (Bcl-2) and proliferating cell nuclear antigen (PCNA) were detected in the I/R group (p<0.001). Histopathologically, it was determined that the Johnsen and Cosentino scores of the testicles were irregular in the I/R group (p<0.001). Proanthocyanidin treatment caused a decrease in MDA, cleaved caspase-3 and Bax levels and an increase in GSH, Vit C, GPx, G6PD, Bcl-2 and PCNA values. Additionally, Johnsen and Cosentino rearranged the scores. The present findings revealed the protective and curative effects of proanthocyanidin in organ damage due to testicular torsion/detorsion-induced ischemia/reperfusion with their antioxidative and antiapoptotic properties.

Evaluation of effects of Tempol on testicular ischemia/reperfusion injury

AimTempol, a synthetic antioxidant compound, has received significant attention for its potential therapeutic applications in recent years, especially against ischemia/reperfusion (I/R) injury. The aim of the present research was to assess the protective effects of Tempol on testicular I/R injury caused by testicular torsion and detorsion (T/D) in rats. MethodsThe subjects were divided into five groups: sham, testicular T/D, testicular T/D with Tempol treatment at 50 and 100 mg/kg, and healthy rats treated with Tempol at 100 mg/kg. Testicular torsion was induced by rotating the left testicles for 2 h, followed by detorsion for 24 h. Testicular tissues were evaluated for gene expression, oxidative stress markers, and histopathology, epididymal sperms were stained and analyzed, and blood serum samples were collected to measure the testosterone hormone. ResultsThe results showed that testicular I/R caused a significant decrease in sperm velocity parameters, viability, and count, as well as an increase in abnormal sperms (p < 0.05). However, treatment with Tempol significantly improved these parameters (p < 0.05). Histopathological analysis revealed severe damage to the testicular tissues, but treatment with Tempol improved the structural integrity of the seminiferous tubules. Testicular I/R also resulted in increased oxidative stress index and decreased testosterone levels significantly (p < 0.05), but Tempol administration mitigated these effects significantly (p < 0.05). Furthermore, the expression of Bax and Bcl2, genes associated with apoptosis, were significantly altered by testicular I/R (p < 0.05), but Tempol prevented these changes significantly (p < 0.05). ConclusionThese findings provide strong evidence that Tempol can effectively prevent testicular I/R injury.

A Case of Metastatic Prostate Cancer with Neuroendocrine Differentiation with Long-Term Survival after Multidisciplinary Therapy

A 74-year-old man visited the urology clinic with the chief complaint of urinary retention in December 2014. Serum level of initial prostate specific antigen (PSA) was 50 ng/ml and he was diagnosed with Gleason Score 4＋4 prostate adenocarcinoma with regional lymphadenopathy (cT3aN1M0). PSA level had declined after the treatment with combined androgen blockade. In November 2018, he was diagnosed with castration resistant prostate cancer (CRPC) as local progression was detected by computed tomography (CT) while PSA level did not increase. Since local symptoms worsened, resulting in repeated hematuria after the treatment with enzalutamide, palliative radiation therapy to the prostate (45 Gy) was performed. Five months later, follow-up CT showed multiple metastasis in bilateral lung and left testicle. Serum level of neuron-specific enolase (NSE) was 24.4 ng/ml without an elevated in serum PSA level. He received rebiopsy of the prostate, but no malignant findings were observed. Consequently, bilateral orchiectomy was performed for diagnosis of left testicular tumor. Pathological examination revealed metastasis of neuroendocrine prostate cancer (NEPC). Chemotherapy using cisplatin and irinotecan was administered after orchiectomy. Complete response of lung lesions was achieved and serum level of NSE decreased within normal range. No recurrence has been confirmed for 4 years after the completion of chemotherapy.

Application of Near-infrared reflectance spectroscopy in the diagnosis of varicocele in children and adolescents

Varicocele is a venous anomaly characterized by the enlargement of the plexus of veins in the testicle. In pediatric cases, indications for surgical intervention in varicocele include palpable dilatation of the enlargement of the plexus veins, intermittent pain in the ipsilateral testicle, and a 20% reduction in size of the ipsilateral testicle compared to the contralateral healthy one. The limitations of evaluating these criteria and the need to assess semen parameters prompt clinicians to explore new diagnostic methods for timely surgical interventions in adolescents. One such promising study involves Near-infrared reflectance spectroscopy (NIRS) in the Near-infrared range. The aim of the research is to evaluate the diagnostic capabilities of NIRS in children with varicocele to determine the indications for surgical intervention. The study included 65 boys aged 11 to 17 years with left-sided grade III varicocele (main group) and 29 healthy boys as a control group. Monitoring of regional oxygen saturation (rSO2) of testicular tissues was conducted using optical spectroscopy. NIRS examination of testicular tissues in both study and control groups showed statistically homogeneous data for regional oxygen saturation in the healthy (right) testicle. However, the NIRS study revealed significantly lower oxygen saturation (rSO2) in the testicular tissue of the left testicle in patients with varicocele compared to the control group. The diagnostic significance of the difference in bilateral NIRS monitoring Δ rSO2 &gt;13% reliably characterized the presence of testicular hypotrophy by more than 20% compared to the healthy contralateral side (AUC=0.64, 95% CI (0.505-0.775), sensitivity – 79%, specificity – 50%, p=0.042). Δ rSO2 &gt;11% values indicated disturbances in spermogram related to oxidative stress (AUC=0.702, 95% DI (0.51-0.88), sensitivity – 82%, specificity – 61%, p=0.031). Therefore, NIRS study data have potential valuable information for the diagnosis and selection of treatment for varicocele in children. The research utilizing Near-infrared Reflectance Spectroscopy revealed a significant potential of this method for diagnosing and assessing the impact of varicocele on the microcirculation of testicular tissue in children. The diagnostic significance of the difference in bilateral monitoring using this non-invasive technique in determining the state of testicles and the possibility of addressing the question of the necessity of surgical intervention is established.

QUANTITATIVE MORPHOLOGICAL ANALYSIS OF THE FEATURES OF REMODELING OF HEMOMICROCIRCULATORY VESSELS IN THE TESTIS OF EXPERIMENTAL ANIMALS AT CONDITIONS OF ETHANOL INTOXICATION

Ethanol is classifi ed as a vascular poison, long-term intoxication of which negatively aff ects almost all organs and systems body of humans and experimental animals. Morphological changes in testes during ethanol poisoning have not been studied enough. The aim of the study was a quantitative morphological analysis of the features of the remodeling of blood vessels of the hemomicrocirculatory bed of the left and right testes at conditions of ethanol intoxication. The structures of the left and right testis of 30 white male rats, which were divided into 2 groups, were morphologically and morphometrically studied. The 1 group included 15 intact animals, the 2-15 rats, which were injected intragastrically with a 30 % ethanol solution at the rate of 2 ml per 100 g of body weight for 28 days once a day. A month after the start of the experiment, the experimental animals were euthanized by bloodletting under thiopental anesthesia. Histological and semithin sections were made from testes. The outer and inner diameters, wall thickness of arterioles, precapillary arterioles, hemocapillaries, postcapillary venules and venules were determined. Quantitative indicators were processed statistically.It was established that twenty- eight days of ethanol intoxication in laboratory sexually mature white male rats leads to pronounced remodeling of the blood vessels of the hemomicrocirculatory bed of the left and right testes, which is characterized by narrowing of the lumens and thickening of the walls of its arterial (arterioles, precapillary arterioles) and exchange (hemocapillaries) vessels. pronounced expansion and thinning of the walls of postcapillary venules and venules, venous hemoptysis, hypoxia, dystrophic- necrotic changes in cells, stromal structures, infi ltration and sclerosis. The revealed remodeling of blood vessels of the hemomicrocirculatory bed in conditions of ethanol poisoning dominates in the left testicle.

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

BackgroundGenitourinary 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 presentationA 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.ConclusionsBiopsy 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.

(267) Penile Length and Circumference in Vietnamese Men

Abstract Introduction Penile size has long been an important fixation in men's lives. Establishing what the normal size of the penis is very important to have a yardstick for men, which is a challenge and depends on the culture, race, and form of measurement applied. Objective To evaluate the size of the penis in flaccidity, erection, and stretch of Vietnamese men. Methods A total of 259 men who visited the Andrology and Fertility Hospital of Hanoi, VietNam were involved in the study between October 2022 and April 2023. Penile measurements (flaccid, erect length/circumference, stretched length) were predominantly taken by 1 investigator using a tape measure and the same measurement technique. All statistical analyses were completed using STATA 17.0. Statistical analysis was performed with the Spearman correlation as tested by the Kolmogorov–Smirnov test (p&amp;lt;0.05). Results The mean age of 259 patients was 29,24 (range: 15–48). The mean penile lengths were: flaccid length 9.21 cm (SD 1.71 cm), flaccid circumference at the middle of the shaft 8.25 cm (SD 0.96 cm), erect length 13.22 (SD 1.46cm), erect circumference at the middle of the shaft 10.42 cm (SD 0.94 cm), and stretched length 12.47 cm (SD 1.61 cm). The mean testicular volume was 12.47 mL (SD 6.37 mL) and 12.65 (SD 4.03 mL) for the left and right testicles, respectively. Stretched length is most closely correlated with erect length with r=0.68. We also observed that the testicular volume, erect length was a significant inverse correlation with age, which ranged from r = -0.14 to -0.21. Conclusions The results of this study help to establish a reference range for male genital size in Vietnam, which should be helpful for urologists and andrologist in counseling patient Disclosure No.

Unmasking the unexpected: Testicular tumour uncovered as a result of scrotal trauma

AbstractWe present a case of a 17‐year‐old male with a testicular tumour diagnosed after trauma. A 17‐year‐old male patient came to our clinic with swelling in the right hemiscrotum. The patient had a history of right scrotal blunt trauma 3 weeks before the admission and had no history of urological surgery or chronic disease. The patient doesn't use tobacco, alcohol, or illicit drugs. Genitourinary system examination revealed swelling and tenderness on palpation in the right hemiscrotum. The right testicle was not palpable. The left hemiscrotum was normal. The left testicle had a normal size and shape. Testicular tumour markers were high (AFP:196 μg/L (N: 0–8 μg/L), b‐HCG: 916 mIU/mL (N: &lt;10 mIU/mL), LDH: 364 U/L (N: 0–265 U/L). Scrotal ultrasonography and magnetic resonance imaging revealed that there were areas of 9 × 9 × 11 cm in size of the right scrotal region without viable testis tissue, hematoma area, and areas compatible with necrosis. These findings were related to intratesticular rupture due to trauma. Abdominal tomography revealed lymphadenopathies of approximately 6 × 3 cm in the anterior paracaval area and approximately 4 × 3 cm in the anterior aspect of the psoas muscle. We performed right radical inguinal orchiectomy on the patient. Testicular tumour markers were still high on the 8th postoperative day (AFP:120 μg/L (N: 0–8 μg/L), bHCG: 680 mIU/mL (N: &lt;10 mIU/mL), LDH: 200 U/L (N: 0–265 U/L)). The testicular tumour was diagnosed as mixed germ cell tumour (50% Yolk Sac, 30% Embryonal Carcinoma, 20% Teratoma). The tumour diameter was 9 cm, surgical margins were intact, there was rete testis invasion, and no tumour was detected in the tunica vaginalis. No tumour invasion was seen in the soft tissue around the spermatic cord (pT2). The patient received 3 cycles of chemotherapy with bleomycin, etoposide, and cisplatin. We suggest that patients presenting with scrotal trauma should be carefully evaluated for testicular malignancy, and if malignancy is suspected, radical inguinal orchiectomy should be preferred for the operation.

Testicular Angiomyolipoma: A Case Report and Review of the Literature

Angiomyolipoma (AML) is a benign mesenchymal tumor, that is composed of thick-walled blood vessels, smooth muscle cells and adipose tissue. They are commonly seen in kidneys, testicles are not a typical location for AML’s; many solid testicular tumors are germ cell malignancies. Here we report the sixth testicular AML case in the literature, to our knowledge. An 80-year-old male undergone bilateral orchiectomy with the diagnosis of local invasive prostate cancer, without any testicular symptoms. Pathological analysis demonstrated a tumor, involving nearly the whole left testicle, composed of muscle cells, vessels and fat tissue, diagnosed as testicular AML. In this article our case is reported and we also make a literature review about testicular AML’s.

Left paratesticular mass mimicking polyorchidism: A case report

We report a rare case of primary scrotal lipoma in a 20-year-old patient which clinically mimics a left triorchidism. The patients presented with the left testicular swelling and the ultrasonography of the scrotum revealed an inhomogeneous hyperechoic mass with an inconclusive report. The left scrotal hemi exploration was planned, and intraoperatively, it was found to be a paratesticular mass with an equivalent size corresponding to the left testicle, separate from the left testicle. The histopathology confirms the lipomatous swelling. The post-operative period remains uneventful and the patient has been on follow-up for the past 1 year with no relapse.

Model of Hypogonadism by Method of Testicular Ischemization and its Morphological Substantiation

This study is devoted to the morphological substantiation of the model of male hypogonadism and establishing the effectiveness of its replacement therapy using morphological methods. Material and methods. 5 groups of adult male Wistar rats (4 individuals each) were studied. Four groups of rats were experimental. Under anesthesia, the left and right spermatic cords with the vascular bundle were tied with a temporary ligature, inducing hypogonadism. In the first two experimental groups of rats, the ligature was applied for 30 and 60 minutes (respectively). Animals in the other two experimental groups received replacement therapy by administering kisspeptin K6. Animals of the third experimental group began to receive kisspeptin a few minutes after restoration of blood flow in the testicle (ex tempore), and rats of the fourth group - after 3 days. The duration of replacement therapy is 7 days. In histological sections of the right and left testicle (n = 8), the number of viable and dying interstitial endocrine cells was counted (under the control of an immunohistochemical reaction with caspase 3), the percentage of these types of cells from their total number was calculated, and the area of viable endocrinocytes was determined. Testosterone levels were determined in the blood of animals of all groups. The significance of differences in the median, upper and lower quartiles of the compared parameters was determined using the nonparametric Mann–Whitney test. Results. It has been established that the modeling of male hypogonadism by applying a double-sided ligature to the vessels of the spermatic cord for 60 minutes and the animals experiencing it for the next 10 days induces pronounced reactive changes and the death of some interstitial cells, inhibition and cessation of spermatogenesis. Kisspeptin KS6, administered ex tempore and regularly after acute ischemia, has a protective effect on interstitial endocrinocytes and testicular spermatogenic cells, including anti-apoptotic, restoring spermatogenesis, probably realized through the activation of the central links of the hypothalamic-pituitary-testicular axis.

HO-1 attenuates testicular ischaemia/reperfusion injury by activating the phosphorylated C-jun-miR-221/222-TOX pathway

AimsHeme oxygenase (HO-1) affords protection against ischaemia/reperfusion (I/R) injury; however, its effects on testicular I/R injury remain poorly explored. Herein, we aimed to examine the effects of HO-1 on testicular I/R injury and elucidate the underlying mechanism. MethodsUsing the TALEN technique, we knocked out the HO-1 gene from rats. In vivo: Thirty hmox+/+ and 30 hmox−/− rats were randomly assigned to six groups: sham-operated (sham), I/R (the left testicle torsion/detorsion) 0 d,I/R 1d, I/R 3d, I/R 7d and I/R 28d. In vitro: GC-1 were suffered from: control,H/R (oxygen-deprivation/reoxygenation),H/R + HO-1 siRNA,H/R + c-Jun siRNA or H/R + HO-1 siRNA + c-jun.We performed immunofluorescence and immunohistochemistry experiments to detect HO-1 nuclear translocation. Flow cytometry was used to detect cell apoptosis and analyse the cell cycle. High-resolution miRNA, mRNA sequencing, reverse transcription-quantitative PCR, and western blotting were performed to identify testicular I/R injury-related genes strongly conserved in HO-1 knockout rats. A double luciferase reporter assay was performed to verify the relationship between C-jun and miR-221/222. Main findingsIn vivo, HO-1 improved the pathological damage induced by testicular I/R. In GC-1 cells, we confirmed the nuclear translocation of HO-1 and its protective effect against hypoxia/reoxygenation (H/R) damage. Accordingly, HO-1 protein itself, rather than heme metabolites, might play a key role in testicular I/R. Gene sequencing was performed to screen for miR221/222 and its downstream gene, thymocyte selection-associated high mobility group box (TOX). HO-1 increased c-Jun phosphorylation in the H/R group, knocked down c-Jun in GC-1 cells, and decreased miR-221/222 expression. Inhibition of HO-1 expression decreased the expression of c-Jun and miR-221/222, which was rescued by adding c-Jun. Dual-luciferase reporter assay confirmed the interaction between c-Jun and miR-221/222. ConclusionsHO-1 could exert a protective effect against testicular I/R via the phosphorylated c-Jun-miR-221/222-TOX pathway.

Morphometric aspects of remodeling of the arterial bed of the testicles in post- resection portal and pulmonary hypertensions.

Aim: To perform a morphometric analysis of the features of vascular remodeling of the arterial bed of the testicles in post-resection portal and pulmonary hypertension. Materials and Methods: The testes of 54 white rats were studied, which were divided into groups: 1st included 16 intact animals, 2nd - 20 rats with pulmonary hypertension, 3rd - 18 individuals with post-resection portal hypertension. Postresection pulmonary hypertension was modeled by right-sided pulmonectomy. Postresection portal hypertension was simulated by removing 58.1 % of the liver parenchyma. Results: The outer diameter of the small-caliber arteries of the left testicle increased by 3.4% (p<0.05) in post-resection arterial pulmonary hypertension, and by 2.9% in post-resection portal hypertension. The inner diameter of the small-caliber arteries of the left testicle decreased by 7.7% (p<0.001) in pulmonary heart disease, and by 6.5% (p<0.01) in post-resection portal hypertension. The Kernogan index decreased by 23.0% (p<0.001), the Vogenvoort index increased by 1.26 times. In case of post-resection portal hypertension, the Kernogan index decreased by 19.0% (p<0.001) and the Wogenvoort's index increased by 1.19 times. The relative volume of damaged endotheliocytes in the small-caliber arteries of the left testis increased 20.6 times (p<0.001) in pulmonary heart disease, and increased 16.3 times (p<0.001) in post-resection portal hypertension. Conclusions: Portal and pulmonary hypertension lead to pronounced remodeling of the arterial bed of the testicles, which is characterized by thickening of the arterial wall, narrowing of their lumen, significant changes in Wogenvoort and Kernogan indexes, atrophy, dystrophy, and necrobiosis of endotheliocytes.

Testicular biometry and certain aspects of epididymal semen of abattoir derived Murrah bull testes

The aim of this study to assess the biometric parameters of abattoir derived testicles of Murrah buffalo bull. Thirty-six pair of Murrah buffalo bull testicles were collected immediately after slaughter from different abattoir, packed in ice chest (4oC) and transferred to DFS Laboratory, College of Veterinary Science and Animal Husbandry, Acharya Narendra Deva University of Agriculture and Technology, Ayodhya, UP, India. The tests were processed within six hours of collection. Various biometric parameters testes (testicular length, circumference, diameter, volume, and weight) epididymis (weight, length and width of caput and corpus as well as length and circumference of cauda) was measured. The epididymal semen was harvested and measured; Volume (0.43±0.02 to 0.52±0.05 ml), concentration (1708±105.2 to 1958±126.8 million/ml) and total sperm output (804.2±30.73 to 931.7±103.2 million) was estimated. All biometric parameters were significantly higher in left testicles than those of right contemporaries. Present findings suggest that aforementioned biometric parameters can be used to judge the normality of testis, furthermore, epididymal semen can be harvested from meritorious Murrah buffalo bulls with sudden or unexpected death.

The structural rearrangement of testicular arteries in case of chronic ethanol intoxication

Prolonged poisoning of the body with ethanol damages almost all its organs and systems. Structural changes in testicular arteries under the influence of chronic ethanol intoxication have not been fully studied. Purpose - to analyze the morphometric parameters of the small caliber arteries of the right and left testicles of rats in case of chronic ethanol intoxication. Materials and methods. 62 laboratory sexually mature male rats was performed. The animals were divided into two groups. The Group 1 (control) included 30 rats, the Group 2 (experimental) - 32 animals. The experimental rats, which were conducted to the experiment, were injected intragastrically with a 30% ethanol solution at the rate of 2 ml per 100 g of body weight for 28 days once a day. Animals were euthanized by heart bleeding under thiopental anesthesia. Histological micro-sections were made from the left and right testicles. Morphometrically, the outer and inner diameters of the arteries, media thickness, adventitia, Vogenvoort and Kernogan indices, the height of endotheliocytes, the diameter of their nuclei, the nuclear-cytoplasmic ratio in these cells, and the relative volume of damaged endotheliocytes were determined morphometrically in small-caliber arteries. Statistical processing of digital data was carried out using Excel (Microsoft, USA) and STATISTICA 6.0 (Statsoft, USA) software. Results. It was established that in case of simulated experimental conditions of chronic ethanol intoxication, the investigated morphometric parameters of the arteries of the left and right testicles changed significantly. In case of chronic intoxication with ethanol in rats, pronounced structural rearrangement of testicular vessels, mainly small arteries, characterized by thickening of the blood vessel’s wall, narrowing of vessels’ lumen, rearrangement of endothelial cells, and an increase in the relative volume of the damaged cells of intima, is established, and is dominant in the left testis. Conclusions. In case of chronic intoxication with ethanol the structural changes in testicular tissues are dominant in the left testis. Pronounced remodeling of small caliber testicular arteries causes endothelial dysfunction, deterioration of blood supply to the testicles, hypoxia, dystrophic and necrobiotic tissue changes, infiltrative and sclerotic processes, which are the pathomorphological basis of male infertility. When carrying out experiments with laboratory animals, all bioethical norms and recommendations were observed. No conflict of interests was declared by the authors.

Splenogonadal fusion: a case report

BackgroundAccessory splenic tissue is a commonly encountered phenomenon in medical literature. Typically, these accessory spleens are found in close proximity to the main spleen, either in the hilum or within the surrounding ligaments. Nevertheless, it is noteworthy that they can also be located in unusual sites such as the jejunum wall, mesentery, pelvis, and, exceptionally rarely, the scrotum. The first documented case of accessory splenic tissue in the scrotum was reported by Sneath in 1913 and is associated with a rare congenital anomaly called splenogonadal fusion. This report describes an infant who presented with a scrotal mass noted by his mother and after examination, investigations, and surgical exploration, it was revealed to be splenogonadal fusion.Case descriptionAn 8-month-old Caucasian male patient presented with a mass in the left testicle and bluish discoloration of the scrotum, which had been incidentally noticed in the previous 2 months. The general physical examination was unremarkable. Other than a palpable scrotal mass that was related to the upper pole of the testis, the rest of examination was unremarkable. Imaging revealed that this mass originated from the tail of the epididymis without infiltrating the testis and tumor markers were normal. On inguinal exploration, a reddish brown 2 × 2 cm mass was found attached to the upper pole and was completely excised without causing any harm to the testis, vessels, or epididymis. Histopathological evaluation confirmed the presence of intratesticular ectopic splenic tissue.ConclusionAlthough uncommon, splenogonadal fusion can be included in the differential diagnosis of a testicular swelling. Accurate diagnosis allows for appropriate treatment planning which helps to avoid unnecessary radical orchiectomy, which can have a significant impact on the patient’s reproductive and psychological wellbeing.
