Corticosteroid injections, eccentric decline squat training and heavy slow resistance training in patellar tendinopathy.
2009
Udgivelsesdato: Sep-28 A randomized-controlled single-blind trial was conducted to investigate the clinical, structural and functional effects of peritendinous corticosteroid injections (CORT), eccentric decline squat training (ECC) and heavy slow resistance training (HSR) in patellar tendinopathy. Thirty-nine male patients were randomized to CORT, ECC or HSR for 12 weeks. We assessed function and symptoms (VISA-p questionnaire), tendon pain during activity (VAS), treatment satisfaction, tendon swelling, tendon vascularization, tendon mechanical properties and collagen crosslink properties. Assessments were made at 0 weeks, 12 weeks and at follow-up (half-year). All groups improved in VISA-…
Electromagnetically Generated Extracorporeal Shock Wave Lithotripsy and Adjuvant Combined Oral Litholysis for Therapy of Symptomatic Gallbladder Ston…
1991
A prospective study was conducted to evaluate effectivity, problems and adverse effects of extracorporeal shock wave lithotripsy (ESWL) using a newly developed electromagnetic biliary lithotriptor (Lithostar Plus, Siemens, Erlangen, FRG) for the treatment of selected patients presenting with symptomatic cholecystolithiasis. In addition to generally accepted criteria for the selection of patients, gallbladder contractility was established and pigment stones were excluded by computed tomography (CT). 80 out of 486 patients (63 females, 17 males, mean age 36, range 17-76 years) were selected for ESWL using a standardized diagnostic program. 62 out of 80 patients participating in the study had …
Contrast-enhanced ultrasonography: usefulness in the assessment of postoperative recurrence of Crohn's disease.
2013
Abstract Aim The aim of this study was to assess whether the contrast-enhanced ultrasonography (CEUS) can increase the value of the ultrasonography in the study of postoperative recurrence of Crohn's disease (CD). Materials and methods 60 patients with CD who had previously undergone ileocolic resection underwent prospectively both CEUS and colonoscopy within a 3-day period. The sonographic examination included evaluation of bowel wall thickness, transmural complications, colour Doppler grade and contrast-enhanced US. In addition a sonographic score was established. The capacity of CEUS to diagnose endoscopic recurrence, as well as its severity, was assessed by calculating the sensitivity, …
Anal endosonographic evaluation after closed lateral subcutaneous sphincterotomy
1998
PURPOSE: The present study was undertaken to evaluate anal endosonographic results of the transverse and longitudinal extent of internal anal sphincter division after closed lateral subcutaneous sphincterotomy and its relationship to outcome with respect to anal fissure recurrence and postoperative anal incontinence. METHODS: Ten patients selected for symptomatic anal fissure recurrence (mean follow-up, 10.9 months) and 41 asymptomatic control patients (mean follow-up, 15.5 months) were reviewed by anal endosonography after closed lateral subcutaneous sphincterotomy. Clinical evaluation was focused on anal fissure recurrence and postoperative anal incontinence. The anal endosonographic stud…
Comparison of Immersion Ultrasound, Partial Coherence Interferometry, and Low Coherence Reflectometry for Ocular Biometry in Cataract Patients
2011
PURPOSE: To compare ocular biometry parameters measured with immersion ultrasound, partial coherence interferometry, and low coherence reflectometry in cataract patients. METHODS: Measurements of axial length and anterior chamber depth were analyzed and compared using immersion ultrasound, partial coherence interferometry, and low coherence reflectometry. Keratometry (K), flattest axis, and white-to-white measurements were compared between partial coherence interferometry and low coherence reflectometry. Seventy-eight cataract (LOCS II range: 1 to 3) eyes of 45 patients aged between 42 and 90 years were evaluated. A subanalysis as a function of cataract degree was done for axial length and…
Carotid atherosclerosis in renal transplant recipients: Relationships with cardiovascular risk factors and plasma lipoproteins
1999
BACKGROUND: Renal transplant recipients have an increased incidence of cardiovascular disease, but less data exist about cerebrovascular atherosclerosis. In this study, we assessed the prevalence of carotid lesions as evaluated by B-mode ultrasonography in a group of renal transplant recipients, and we evaluated univariate and multivariate relationships between common risk factors and plasma lipoproteins and carotid lesions. METHODS: Fifty-seven renal transplant recipients and 113 age- and gender-matched controls underwent a complete clinical visit for the evaluation of risk factors present. In all subjects, a blood sample was collected for lipoprotein determination, and an ultrasound high-…
Comparison of selective internal iliac pharmaco-angiography, penile brachial index and duplex sonography with pulsed Doppler analysis for the evaluat…
1990
AbstractBetween July 1987 and February 1988 selective internal iliac angiography was performed before and after intracavernous injection of papaverine plus phentolamine in 43 patients with erectile dysfunction. In 63% of the patients stenosis or occlusion of the pudendal artery was found. The penile brachial index was calculated and duplex sonography with pulsed Doppler analysis was performed in 23 patients. Angiography and penile brachial index correlated in only 39% of the patients, whereas selective internal iliac angiography and duplex sonography correlated in 91% (21 of 23). In 2 patients duplex sonography with pulsed Doppler analysis rendered better information about penile arterial p…
Detection of intracranial circulatory arrest in brain death using cranial CT-angiography.
2011
Background and purpose Computed tomographic-angiography (CT-A) is becoming more accepted in detecting intracranial circulatory arrest in brain death (BD). An international consensus about the use and the parameters of this technique is currently not established. We examined intracranial contrast enhancement in CT-A after clinically confirmed BD, compared the results with electroencephalography (EEG) and Transcranial Doppler Ultrasonography (TCD) findings and developed a commonly applicable CT-A protocol. Methods Prospective, monocentric study between April 2008 and October 2011. EEG, TCD and CT-A were performed in 63 patients aged between 18 and 88 years (mean, 55 years) who fulfilled clini…
Preoperative diagnostics in pancreatic carcinoma: would less be better?
1998
Objective: The objective of this study was to investigate the value of preoperative diagnostics in patients with pancreatic carcinoma in terms of tumor diagnosis and evaluation of resectability. Patients/Methods: From 1 September 1985 to 31 December 1997, 408 patients shown by histology to have a ductal (n=330) or periampullary carcinoma (n=78) were treated at our hospital. Results: In determining the presence of tumor, ultrasonography and computed tomography (CT) had a sensitivity of 88.3% and 94.0%, respectively; combined, they had a sensitivity of 96.2%. Endoscopic retrograde cholangiopancreatography (ERCP) had a sensitivity of 96.2%. Preoperative aspiration biopsy cytology had a sensiti…
A 30-Year, Population-Based Study Shows Improved Management and Prognosis of Hepatocellular Carcinoma
2010
Background & Aims Little is known about the impact of changes in the management of hepatocellular carcinoma (HCC) over time. We assessed trends in the pattern of care and in prognosis at a population level. Methods Data on diagnostic conditions, treatment, and prognosis from 1976–2005 were collected by the population-based digestive cancer registry of Burgundy (France). A nonconditional logistic regression was used to identify factors associated with treatment for cure. A multivariate relative survival analysis was also performed. Results The context of HCC diagnosis has changed; the proportion of asymptomatic patients increased from 5.6% (1976–1985) to 37.2% (1996–2005). The proportion of …
