Abstract Purpose. To evaluate the effect of clinical varicocele on testicular microcirculation using spectral Doppler analysis. Methods. Forty‐nine young and healthy volunteers were enrolled in this prospective study. Varicocele grades determined according to sonographic parameters. Patients with left‐sided classified as patient group (n = 15), while remaining patients served controls 34). Spectral measurements arteries (peak systolic/end diastolic velocity, resistance index, pulsatility...

Objectives: Fabry's disease is an X-linked inherited, rare, progressive, lysosomal storage disorder, affecting multiple organs due to the deficient activity of α-galactosidase A (α-Gal A) enzyme. The prevalence has been reported be 0.15–1% in hemodialysis patients; however, information on chronic kidney not dialysis lacking. This study aimed determine disease.Methods: patients older than 18 years, enclosing KDIGO 2012 definitions, dialysis, were enrolled. Dried blood spots Guthrie papers...

To examine the mammography and ultrasonography findings of patients who have a final histopathological diagnosis sclerosing adenosis after breast biopsy, to evaluate follow-up results underwent core needle biopsies.Seventy-six 723 biopsy in our institution were diagnosed with on examination. Mammography from these 76 lesions analyzed retrospectively. Thirty-seven sampled by image-guided biopsy; remaining excised surgically. Mammograms ultrasound images re-evaluated, post-biopsy medical...

To investigate the effect of pre-procedural waiting period and anxiety level on pain perception during transrectal ultrasound-guided prostate biopsy.Sixty patients who had undergone biopsy were enrolled in this prospective study. The subjects asked to fill out State-Trait Anxiety Inventory Scale-1 measure state at three times: 1) time procedure request, 2) before procedure, 3) getting result. Just after biopsy, a visual analog scale evaluate resulting from biopsy.The mean score was well...

Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disease characterized by progressive joint deformity and increased mortality. RA patients typically exhibit elevated plasma levels of inflammatory markers, contributing to endothelial dysfunction arterial wall stiffness-a recognized marker subclinical atherosclerosis heightened cardiovascular risk. This study aimed evaluate carotid stiffness in using ultrasound (US) imaging modality with speckle tracking strain (STCS) software,...

Background Breast tomosynthesis is more sensitive than mammography and can detect lesions that are not always visible with conventional methods such as digital (MG) ultrasonography (US). No standardized approach available for the management of detectable but on MG or US. Purpose To review suspicious breast detected two-dimensional (2D) US to determine options these lesions. Material Methods Ethical committee approval was obtained. The radiological records, biopsy surgery results, follow-up...

Abstract We report on a case of 32‐year‐old man referred for evaluation painless left testicular mass suggesting tumor. Previous history was uneventful except 3‐year systemic brucellosis without epididymo‐orchitis. Radical inguinal orchidectomy performed. Clinical and histopathological findings indicated brucellar abscess the testis. Even in absence symptoms, possible relapse as an formation testis should be considered rare cause patients who live endemic regions.

Objectives The aim of the study was to scrutinize value qualitative elastography in diagnosis salivary gland masses. Methods Sixty patients were enrolled this prospective study. Patients aged between 1 and 91 years (mean age, 48.8 ± 20.48) with a mass studied real‐time elastography. All examined by examiner, blinded all relevant data. On elastography, masses scored into 4 types according their stiffness compared normal tissue. Scores 3 accepted as signs malignancy. Sensitivity, specificity,...

Acquired nasolacrimal duct obstruction may occur simultaneously and possibly as a consequence of sinonasal disease, because the system is anatomically related to important nasal sinus structures.Thirty-seven patients with canal (42 eyes) were evaluated paranasal computerized tomography (CT) determine presence abnormalities if any. All underwent endoscopic dacryocystorhinostomy (end-DCR) accompanying pathology was treated also in same session.Paranasal CT examinations revealed one or more 26...

Objective. The purpose of this study was to determine whether hydrocele has any effect on the volume and shape ipsilateral testis can be implicated as a cause testicular ischemia. Methods. Group 1 consisted 23 patients with unilateral idiopathic hydrocele, whereas 30 healthy men constituted group 2. All underwent scrotal ultrasonography by which dimensions in craniocaudal (Dcc), anteroposterior (Dap), mediolateral axes were measured, followed calculation Dcc/Dap ratio volume. By color...

Abstract Acute kidney injury ( AKI ) occurs in many different situations and may have a variable prognosis influenced by clinical setting, underlying cause, comorbidity. This is important because of the high mortality morbidity risk affecting people around world. Near‐drowning related requiring hemodialysis very seldom reported literature. Although cardiovascular respiratory disorders are more frequently seen after this entity, we aimed to emphasize rare but dangerous complication...
