Klinefelter syndrome is a frequent cause of hypogonadism, but despite hundreds of publications on different aspects of Klinefelter syndrome, only a few studies dealt with sexual dysfunction. In particular, testosterone is critical for various aspects of sexual response, but its role on sexuality in Klinefelter syndrome patients is debatable and no studies have evaluated the efficacy of testosterone treatment on sexual dysfunction in these subjects. Furthermore, the impact of psychological and relational aspects on sexual function of Klinefelter syndrome subjects is poorly defined...

Background: Ultrasonographic homogeneity is an important differential finding between Warthin tumor and pleomorphic adenoma, two types of benign parotid gland tumors, with the former likely to be heterogeneous and the latter homogeneous. However, differences in the performance of ultrasound machines or the homogeneity cut-off level affect the judgment of ultrasonographic homogeneity. Therefore, in this study, we adopted a novel system for classifying the composition of tumors via ultrasonography, using anechoic area as a substitute for differences in homogeneity to differentiate between Warthin tumors and pleomorphic adenomas...

Herein we report a case of a 38-year-old men who presented with acute suprapubic pain caused by a tubular, hypoechoic, non-compressible, inguinal mass with no flow evident on color Doppler sonography. The history of the patient, the clinical signs of local inflammation and tenderness on palpation as well as the results of the Doppler ultrasound examination led to the diagnose of an inguinal hernia with bowl incarceration. However, due to a remaining uncertainty whether a bilateral or unilateral hernia was immanent and whether the bowl incarceration was caused by a right or left sided hernia the on-call surgeon initiated a computed tomography (CT) scan...

Background: Testicular torsion is one of the causes of acute scrotum and it requires timely evaluation and surgical treatment. Color Doppler is considered investigation of choice, but it may delay treatment, as, many times, it may not be available for emergency situations. Barbosa et al. created Testicular Workup for Ischemia and Suspected Torsion (TWIST) score based on clinical parameters for clinical diagnosis of testicular torsion. We have evaluated this score in our population. Materials and Methods: We retrospectively calculated TWIST score in patients of acute scrotum admitted to tertiary teaching institute...

Echocardiography is an invaluable tool for characterizing cardiac structure and function in vivo. Technological advances in high-frequency ultrasound over the past 3 decades have increased spatial and temporal resolution, and facilitated many important clinical and basic science discoveries. Successful reverse translation of established echocardiographic techniques, including M-mode, B-mode, color Doppler, pulsed-wave Doppler, tissue Doppler and, most recently, myocardial deformation imaging, from clinical cardiology into the basic science laboratory has enabled researchers to achieve a deeper understanding of myocardial phenotypes in health and disease...

Polyorchidism is a rare condition usually incidentally discovered in young patients investigated with ultrasound for unrelated reasons. It is characterized by the presence of unilateral or, rarely, bilateral supernumerary testes which, depending on the type of polyorchidism, may have their own epididymis and vas deferens. Ultrasound, including B-mode and color Doppler technique, represents the primary imaging modality for the evaluation of scrotal diseases, including the characterization of supernumerary testes, which normally appear identical to the ipsilateral testicular parenchyma on every ultrasonographic technique performed...

Healthcare providers who use peripheral vascular and cardiac ultrasound require specialized training to develop the technical and interpretive skills necessary to perform accurate diagnostic tests. Assessment of competence is a critical component of training that documents a learner's progress and is a requirement for competency-based medical education (CBME) as well as specialty certification or credentialing. The use of simulation for CBME in diagnostic ultrasound is particularly appealing since it incorporates both the psychomotor and cognitive domains while eliminating dependency on the availability of live patients with a range of pathology...

If pulse pressure, one of the mechanical stresses, is a risk factor for atherosclerotic cardiovascular disease, then atherosclerosis should be progressive in aortic regurgitation which is a representative disease with increased pulse pressure. This cross-sectional study included 1,149 patients. We examined the influence of aortic regurgitation on maximum intima-media thickness or brachial-ankle pulse wave velocity. The degree of aortic regurgitation was classified into 4 grades by color Doppler examination...
