PURPOSE: Many physicians encounter confusion and difficulty in distinguishing testicular torsion (TT) from torsion of the appendix testis (TAT) in patients with acute scrotum because of the overlapping signs and symptoms. The objective of our study was to evaluate the clinical features and signs that can help distinguish TT from TAT. PATIENTS AND METHODS: We performed a retrospective study of patients with surgically confirmed TT and TAT at our institute from January 1990 to December 2013...

OBJECTIVES: Although the African elephant (Loxodonta africana) is classified as endangered by the International Union for Conservation of Nature (IUCN), in some isolated habitats in southern Africa, contraception is of major interest due to local overpopulation. GnRH vaccination has been promoted as a non-invasive contraceptive measure for population management of overabundant wildlife. We tested the efficacy of this treatment for fertility control in elephant bulls. METHODS: In total, 17 male African elephants that were treated with a GnRH vaccine were examined in two groups...

Testicular adrenal rest tumors (TARTs) are common cause of infertility in males with congenital adrenal hyperplasia (CAH). We studied the role of genotype and disease regulation on TART development, their impact on gonadal function, and frequency in 47 21-hydroxylase deficiency (21-OHD) and four 11-hydroxylase deficiency (11-OHD) male patients. Testicular ultrasound (TU), genotype, hormonal measurement in 51, and spermiogram in five patients were performed. TARTs were detected in 14 SW21-OHD and one 11-OHD patient: 1/8 patients aged <7 years (1...

Male pelvic emergencies are uncommon, and symptoms typically include scrotal pain, scrotal enlargement, or a palpable scrotal mass or all of these. Ultrasound is often the first-line modality for evaluation of male pelvic emergencies, which may be stratified into vascular, infectious, or traumatic causes. Entities such as testicular torsion, Fournier gangrene, and testicular dislocation are surgical emergencies and should not be missed or misdiagnosed, as this may cause a significant delay in urgently necessary treatment...

Accurate determination of the testes volume and prediction of the daily sperm output (DSO) is valuable information for reproductive management of a stallion. The aim of this study was to compare different methods for measuring the testes volume, including caliper, 2D and 3D ultrasound. Special emphasis was on feasibility of 3D volume analysis. First, 22 castrated testes were measured and derived volumes were compared with volumes determined via volume displacement in a graded cylinder with saline solution. Then, during the breeding season, testes sizes of 52 stallions were measured in vivo and analyzed...

Primary testicular lymphoma (PTL) is a rare form of extranodal lymphoma and accounts for approximately 1 to 2 % of all non-Hodgkins lymphoma and 5 % of testicular malignancies. PTL typically affects patients older than 60 years. The most common clinical symptom is painless scrotal swelling. The ultrasound of testicles followed by orchiectomy and histological and imunohistochemical examinations are the most important tools for diagnostic assessment. Diffuse large B cell lymphoma (DLBCL) is the most common histological type of PTL...

Few chemotherapeutics have had such an impact on cancer management as cis-diamminedichloridoplatinum(II) (CDDP), also known as cisplatin. The first member of the platinum based drug family, CDDP's potent toxicity in disrupting DNA replication has led to its widespread use in multi-drug therapies, with particular benefit in patients with testicular cancers. However, CDDP also produces significant side effects that limit the maximum systemic dose. Various strategies have been developed to address this challenge including encapsulation within micro- or nanocarriers and the use of external stimuli such as ultrasound to promote uptake and release...

Testicular melanotic neuroectodermal tumor of infancy (MNTI) is extremely rare, with 2 cases reported in the literature. Its rarity and rapid and infiltrative growth pattern pose a diagnostic challenge. A previously healthy 3-month-old male, presented with a history of worsening left hemiscrotal swelling for 1 week. An outside ultrasound was suggestive of testicular torsion. Left orchiectomy demonstrated a mass occupying almost entire testicle with a variegated cut surface, with areas of pigmentation, necrosis, and hemorrhage...

Congenital adrenal hyperplasia refers to the non-malignant enlargement of adrenal gland tissue as a result of deficiency of one of several enzymes involved in adrenal hormone synthesis, secondary to a genetic mutation. 11 - Beta hydroxylase is one such enzyme, and its deficiency is a rare cause of Congenital Adrenal Hyperplasia. We describe the case of an 18-year old man who presented to us with an acute right ganglio-capsular bleed, hypertension and bilateral scrotal swelling. Investigations revealed hypokalemia, and normal renal and cardiac functions...

Pediatric emergency medicine physicians may be able to use point-of-care ultrasound (POCUS) as a tool to evaluate abdominal wall masses. We present a case of a 2-month-old infant with a lower abdominal mass identified as a hernia sac by POCUS. It was initially thought to represent a Spigelian-type abdominal wall hernia but subsequently determined to be an unusual presentation of an inguinal hernia with testicular entrapment. We review each of these diagnoses in addition to relevant POCUS findings.

A 24-year-old man presented with a 2-week history of a painless right testicular mass; ultrasound demonstrated a dense, solitary calcified mass. The patient elected observation after further workup showed no evidence of metastasis.A repeat ultrasound 3 months later showed interval growth and the patient underwent right radical orchiectomy. Pathology was consistent with pure embryonal carcinoma of the testis. Calcified testicular masses are typically benign but do carry a differential of spermatic granuloma, large-cell calcifying Sertoli cell tumour, trauma, tuberculosis, filariasis, calcified Leydig cell tumour and burned-out testicular tumour...

INTRODUCTION AND OBJECTIVES: Although standard surgical treatment of a testicular tumour is orchiectomy, use can be made of testis-sparing surgery in selected cases, based on tumour markers, tumour size, and histopathological findings. Our objective is to become acquainted with the indications of testis-sparing surgery as a treatment for the incidental finding of a palpable and non-palpable testicular mass. MATERIAL AND METHODS: A retrospective study was conducted on 22 patients younger than 18 years diagnosed with a testicular tumour between 2000 and 2014...
