BACKGROUND The etiology of sudden sensorineural hearing loss (SSNHL) is still unclear and is most probably diverse. OBJECTIVE To determine the relationship between vertebrobasilar circulation and hearing in patients with SSNHL treated with pentoxifylline. DESIGN Case-control study of 32 consecutive patients with SSNHL. METHODS Patients with onset of SSNHL within 72 hours were treated with...

PURPOSE Arterial media calcification (AMC) is often the only vascular calcification (VC) present in young patients with chronic renal failure and its presence is associated with higher mortality rates. Currently, X-ray imaging (as a standard approach) is able to show AMC in areas without diffuse overlapping arterial intimal calcification (AIC), but X-ray imaging only allows us to identify this ...

AIM To determine if there are different penile hemodynamic patterns between sildenafil non-responders and responders by using color Doppler ultrasonography. METHODS A total of 69 erectile dysfunction (ED) patients aged 22-79 years were enrolled into the present study. Thirty-eight (55.1%) men with ED who did not respond to four attempts of treatment with 100 mg sildenafil after re-education w...

OBJECTIVE To evaluate ultrasonographic methods, including the Doppler technique, as measures of synovial inflammation in finger joints of patients with rheumatoid arthritis. METHODS Ultrasonography was performed with a high frequency transducer (13 MHz). Evaluation of the sonographic data was conducted by two independent observers and included measurement of synovial area and thickness (grey ...

Background: In recent years, many reports have investigated the usefulness of brachial artery blood flow (BAF) measured by ultrasonography as an evaluation index for vascular access (VA) stenosis hemodialysis patients. However, mechanism VA dysfunction, despite BAF being higher than preset flow, has not been clarified to date. Methods: The relationship between actual blood-removal and recircula...

Hepatorenal failure, a well-recognized complication of established liver disease, is characterized by early renal hemodynamic changes (vasoconstriction) before clinically recognized kidney disease. This renal vasoconstriction (increased renal vascular resistance) should be detectable noninvasively by Doppler ultrasonography. We studied whether renal Doppler ultrasonography detects abnormalities...

Abstract Galactoceles are benign lesions formed at the expense of breast glandular tissue. Its occurrence in boys is exceptional, with isolated reports scientific literature. We present case a 2-year-old boy who debuted unilateral enlargement 18 months evolution, no other associated symptoms. Initial hormonal study showed alterations. Ultrasonography presence homogeneous 5-cm retroareolar cyst....

Fenestrations of vertebral arteries are considered to be rare abnormalities observed in angiographic and autopsy studies. They result from vascular abnormalities that occur during the embryological development of vertebral artery. Fenestrations of the vertebral artery are vascular structures having 2 different lumens and endothelium layers, sharing either the same or separate adventitia layers....

BACKGROUND Use of a calcineurin inhibitor (CNI) immunosuppressant following kidney transplantation is associated with development of vasomotor nephrotoxicity. This study was undertaken to evaluate and compare the influences of CNI-based and CNI-free immunosuppressant regimens on two intrarenal vascular resistance parameters, the resistive index (RI) and the pulsatility index (PI), in renal tran...

BACKGROUND AND PURPOSE Circulating lipoprotein-associated phospholipase A(2) (Lp-PLA(2)) has emerged as a novel biomarker for cardiovascular diseases. Our aim was to determine Lp-PLA(2) mass and activity in a selected cohort of first-ever transient ischemic attack (TIA) or ischemic stroke patients with intracranial atherosclerotic disease (ICAD) and to investigate its relationship with the pres...
