Sonographic examination of epiaortic vessels in patients with peripheral vertigo
2010
To evaluate the utility of echo-color-Doppler ultrasonography (CDU) of extracranial brain-supplying vessels in patients with peripheral vertigo of unknown origin.One-hundred-fifty-six patients (study group; 42 male and 114 female; mean age 61.86 ± 14.14) and 161 patients (control group; 80 male and 81 female; mean age 62.31 ± 13.69) were prospectively evaluated with CDU of extracranial brain-supplying vessels. Plaques in common and/or internal carotid artery (CA), arterial wall intima-media thickness (IMT) of common CA and peak systolic velocity (PSV) and resistive index (RI) of vertebral arteries (VA) were evaluated. Parametric (t-test) and non-parametric (Mann-Whitney U-test and Kolmogoro…

Incidence of peripheral intravenous catheter failure and complications in paediatric patients: Systematic review and meta analysis.
2020
Background: Most paediatric patients have at least one peripheral intravenous catheter insertion during their hospitalisation. Despite the important function of peripheral intravenous catheters for delivery of intravenous therapy, failure and complications rates are widely reported; however these results have not been synthesised. Objective: To provide an overall estimate of peripheral intravenous catheter failure and related complications in the paediatric population. Design: Systematic review and meta-analysis Data sources: The electronic databases, Cochrane Central Register of Controlled Trials, US National Library of Medicine National Institutes of Health, Cumulative Index of Nursing an…
Pigmented esthesioneuroblastoma showing dual differentiation following transplantation in nude mice
1989
Esthesioneuroblastoma (ESTH) is a neuroepithelial-cell-derived neoplasm of the olfactory mucosa composed of homogeneous small round cells which contain neurosecretory granules. Melanin has been detected in such tumours only occasionally. Here we describe a new case of ESTH with divergent differentiation. The primary neoplasm was found in a 67 year-old female, involving the left nasal and maxillary sinus; she died of cerebral metastasis ten months after diagnosis. Histologically only small round cells were seen, with S-100 and NSE positivity. Electron microscopy revealed neurosecretory granules and filaments, as well as the occasional presence of melanosomes. A nude mice xenograft line has b…
Uniform response of c-raf expression to differentiation induction and inhibition of proliferation in a rat rhabdomyosarcoma cell line
1990
The clonal rat rhabdomyosarcoma cell line BA-HAN-1C is composed of proliferating mononuclear cells, some of which spontaneously fuse to terminally differentiated myotube-like giant cells. Both the induction of differentiation by retinoic acid (RA) and by sodium butyrate (NaBut), as well as the inhibition of proliferation by fetal calf serum (FCS)-depleted medium uniformly resulted in the same effects. There was a significant (p less than 0.001) inhibition of proliferation and induction of cellular differentiation, as evidenced by a significant (p less than 0.05) increase in creatine kinase activity. Furthermore, after exposure to RA-supplemented or FCS-depleted medium, a significant (p less…
The Role for Combined Antithrombotic Therapy with Platelet and Coagulation Inhibition After Lower Extremity Revascularization
2021
Evidence for antithrombotic treatment following lower extremity revascularization (LER) for peripheral artery disease (PAD) is limited, leading to weak and conflicting guideline recommendations and heterogeneous practice patterns. This variability in post-LER antithrombotic treatment raises quality-of-care issues that have long been under-studied. This Viewpoint reviews the most updated guidelines, currently-available evidence, and contemporary data about practice patterns and practitioner opinions in this area. Particular attention is paid to distinctions between antiplatelet therapy, anticoagulant therapy, and combination therapy in light of the recent VOYAGER-PAD (Vascular Outcomes Study…
Antithrombotic therapies in aortic and peripheral arterial diseases in 2021: a consensus document from the ESC working group on aorta and peripheral …
2021
AbstractThe aim of this collaborative document is to provide an update for clinicians on best antithrombotic strategies in patients with aortic and/or peripheral arterial diseases. Antithrombotic therapy is a pillar of optimal medical treatment for these patients at very high cardiovascular risk. While the number of trials on antithrombotic therapies in patients with aortic or peripheral arterial diseases is substantially smaller than for those with coronary artery disease, recent evidence deserves to be incorporated into clinical practice. In the absence of specific indications for chronic oral anticoagulation due to concomitant cardiovascular disease, a single antiplatelet agent is the ba…
Comprehensive management of risk factors in peripheral vascular disease. Expert consensus
2020
There is currently a degree of divergence among the main clinical practice guidelines on the management of risk factors for peripheral arterial disease (PAD). This project aims to gain understanding of the management of PAD risk factors in clinical practice and to reach a multidisciplinary consensus on the strategies to be followed in order to optimize its identification, treatment, and follow-up.A multidisciplinary consensus following the Delphi methodology.Professionals (n = 130) with extensive experience in PAD participated in this consultation. The results suggest that in order to optimize the control of risk factors, efforts should be aimed at: (1) promoting the involvement and awarene…
Neuromuscular fatigue differs following unilateral vs bilateral sustained submaximal contractions
2011
The purpose of the present study was to compare the mechanisms of fatigue induced by a unilateral vs a bilateral submaximal isometric knee extension. Ten physically active men completed two experimental sessions, randomly presented. They were asked to maintain an isometric knee extension force corresponding to 20% of the maximal voluntary contraction (MVC) until task failure with one leg (unilateral) vs two legs (bilateral). MVCs were performed before and after the sustained contraction. Transcutaneous electrical stimuli were used to examine central (voluntary activation) and peripheral (peak doublet force at rest) fatigue on the exercised leg. Time to task failure was significantly shorter…
Effect of acetyl-l-carnitine in the treatment of diabetic peripheral neuropathy : A systematic review and meta-analysis
2017
Background/aim: Deficiency of acetyl-L-carnitine (ALC) and L-carnitine (LC) appears to play a role in peripheral diabetic neuropathy, although the evidence in humans is still limited. We conducted a systematic review and meta-analysis investigating the effect of ALC on pain and electromyographic parameters in people with diabetic neuropathy. Methods: A literature search in major databases, without language restriction, was undertaken. Eligible studies were randomized controlled trials (RCTs) or pre-and post-test studies. The effect of ALC supplementation on pain perception and electromyographic parameters in patients with diabetic neuropathy was compared vs. a control group (RCTs). The effe…
