1. Doppler Ultrasound Testing Suggests Hemorrhoids in Females may be a Consequence of Impaired Blood Flow Associated with Pelvic Organ Prolapse
Abstract Background It has been observed that there is a high incidence of hemorrhoids in female patients with pelvic organ prolapse. Also, in these patients, hemorrhoidal disease improves after the surgical correction of the pelvic organ prolapse. Objective Our hypothesis was that a cause-effect relationship between pelvic organ prolapse, and hemorrhoids

2. Renal resistive index in patients with polycystic ovary syndrome
ABSTRACT Objective: Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age. The renal resistive index (RRI) is a measure of renal arterial resistance to blood flow. The aim of this study was to investigate the renal resistive index levels of patients with PCOS. Subjects and methods: A total of 216 women were included i

3. Analgesic effects of a capacitive-resistive monopolar radiofrequency in patients with myofascial chronic neck pain: a pilot randomized controlled trial
RESUMO ANTECEDENTES: Até a data, há uma falta de estudos prévios para tratar a dor no pescoço por radiofrequência (RF) monopolar capacitiva resistiva. O objetivo deste estudo foi investigar o efeito imediato da radiofrequência monopolar capacitiva resistiva (RF = 448 kHz) versus placebo em (1) redução da intensidade da dor no pescoço em pontos de g

4. Ultrasound evaluation of obstructive uropathy and its hemodynamic responses in southwest Nigeria
ABSTRACT Purpose: To determine the renal arterial hemodynamic changes induced by obstructive uropathy using Doppler ultrasonography.
Materials and Methods: 60 adult subjects with suspected obstructive uropathy and 60 asymptomatic apparently healthy controls with normal renal ultrasound featur

5. Is quantitative diffusion-weighted MRI a valuable technique for the detection of changes in kidneys after extracorporeal shock wave lithotripsy?
Objective The aim of this study was to evaluate the capability and the reliability of diffusion-weighted imaging (DWI) in the changes of kidneys occurring after extracorporeal shock wave lithotripsy (ESWL) treatment for renal stones. Materials and Methods A total of 32 patients who underwent ESWL treatment for renal stone disease between June and December 2

6. Can Doppler or contrast-enhanced ultrasound analysis add diagnostically important information about the nature of breast lesions?
OBJECTIVES: Despite evidence suggesting that Doppler ultrasonography can help to differentiate between benign and malignant breast lesions, it is rarely applied in clinical practice. The aim of this study was to determine whether certain vascular features of breast masses observed by duplex Doppler and color Doppler ultrasonography (before and/or after micr

7. The role of the resistive index in Hashimoto's thyroiditis: a Sonographic pilot study in children
OBJECTIVE: The role of Doppler ultrasonography in the diagnosis of diffuse thyroid diseases is not well established. In particular, Doppler ultrasonography findings in children with Hashimoto's thyroiditis are very limited. We examined gray-scale and Doppler ultrasound findings in Hashimoto's thyroiditis in children in an attempt to understand the feasibilit

8. Evaluation of the resistive index of prostatic blood flow in benign prostatic hyperplasia
OBJECTIVE: The aim of this work is to study the resistive index (RI) of prostatic blood flow by transrectal power Doppler sonography in benign prostatic hyperplasia (BPH) to determine its correlation with other parameters of BPH. MATERIALS AND METHODS: Eighty-two male patients aged 52-86 years with lower urinary tract symptoms (LUTS) due to BPH were included

9. Repetibilidade da avaliação do grau de dispnéia através de um sistema de cargas resistivas inspiratória em indivíduos normais
Introduction: Studies have shown that the magnitude of externally added inspiratory resistive loads follows a predictable relationship with dyspnea perception, in which the psychological magnitude grows as a power of the added loads. The effect of repeated measures of dyspnea perception using resistive loading system is not clear in literature. Objective: To

10. The effectiveness of low laser therapy in subacromial impingement syndrome: a randomized placebo controlled double-blind prospective study
OBJECTIVES: Conflicting results were reported about the effectiveness of Low level laser therapy on musculoskeletal disorders. The aim of this study was to investigate the effectiveness of 850-nm gallium arsenide aluminum (Ga-As-Al) laser therapy on pain, range of motion and disability in subacromial impingement syndrome. METHODS: A total of 52 patients (33

11. O exame ultrassonográfico modo B, Doppler colorido e pulsado na avaliação da doença renal crônica em felinos / Ultrasonographic evaluation of chronic kidney disease in cats by B mode, color and spectral Doppler
Doença renal crônica é uma afecção comum em cães e gatos, especialmente em gatos senis, e importante causa de morbidade e mortalidade. Além da idade avançada, fatores como alterações congênitas, alimentação inadequada, utilização de drogas nefrotóxicas, intoxicações e doenças infecciosas predispõem às lesões do parênquima renal.

12. Doppler sonographic findings in testicular microlithiasis
OBJECTIVE: The aim of this prospective study was to compare the resistive index (RI) values, which is a parameter of testicular parenchymal perfusion, in testicular microlithiasis (TM) cases and normal cases. MATERIALS AND METHODS: 2179 volunteers, all healthy men (17-42 years of age) from the Annual Army Reserve Officer Training Corps training camp were inc
