Management of macular edema due to branch retinal vein occlusion with intravitreal injections of pegaptanib sodium
2009
Purpose To evaluate the efficacy of Pegaptanib Sodium as single therapy for macular edema due to non-ischemic branch retinal vein occlusion. Methods In this uncontrolled prospective pilot study 17 patients have been included with non-ischemic branch retinal vein occlusion. All of them showed macular edema in the OCT with central foveal thickness higher than 350 microns (mean, 541 +/- 140) and decrease in visual acuity lower than 0,5 Snellen ETDRS charts notation (mean, 0,16+/-0,14). After an initial injection of Pegaptanib Sodium evaluations were programmed every 5 weeks and further retreatments were developed in cases with macular thickness higher than 300 microns. No other therapies were …
Nd:YAG-Laserung einer retrohyaloidalen Blutung nach Venenastverschluss
2006
Background A retrohyaloidal haemorrhage can be caused by different underlying diseases. Usually dense haemorrhages are treated by early vitrectomy. We want to report the successful treatment of a retrohyaloidal haemorrhage by means of Nd:YAG laser membranotomy. Materials and methods A 47-year-old man noticed two weeks before presentation a sudden visual loss in the left eye. Visual acuity on the first visit was c. c. 20/32 OD and c. c. 20/400 ex. OS. Dilated fundus examination of the left eye showed multiple intraretinal haemorrhages in the superior periphery and a dense retrohyaloidal haemorrhage over the macula. Anamnestic risk factors for ocular bleeding were systemic hypertension in con…
Sonographische Charakteristika laterozervikaler Raumforderungen
2001
UNLABELLED Sonography of the head and neck mainly focuses on tumours of the lateral neck. Even though most of these masses are enlarged lymph nodes, other tumors have to be considered. AIM To determine whether different pathological cervical masses display a characteristic sonographic morphology. METHOD On the basis of 530 sonographical findings in the neck, typical ultrasound characteristics either in B-scan or in colour coded sonography were demonstrated. RESULTS Apart from enlarged lymph nodes, it was possible to differentiate other occurrences such as branchial cysts, abscesses, laryngoceles, lipomas, neurinomas, glomus tumours, paragangliomas and also fibromas by their specific ultraso…
MRI in the Diagnosis of Right Ventricular Dysplasia
2006
ARVD is part of the group of cardiomyopathies characterised pathologically by fibrofatty replacement of the right ventricular myocardium and clinically by right ventricular arrhythmias of the LBBB pattern. Pathogenesis, prevalence, and aetiology are yet not fully known. The diagnosis of ARVD is based on the presence of structural, histological, electrocardiographic, and genetic factors. Therapeutic options include antiarrhythmic medication, catheter ablation, implantable cardioverter defibrillation, and surgery. Angiography and echocardiography lack sensitivity and specificity in the diagnosis of ARVD. MR imaging allows a three-dimensional evaluation of especially the right ventricle, and p…
Non-responders to cardiac resynchronization therapy: Insights from multimodality imaging and electrocardiography. A brief review
2016
Background Cardiac resynchronization therapy (CRT) is a successful strategy for heart failure (HF) patients. The pre-requisite for the response is the evidence of electrical dyssynchrony on the surface electrocardiogram usually as left bundle branch block (LBBB). Non-response to CRT is a significant problem in clinical practice. Patient selection, inadequate delivery and sub-optimal left ventricle lead position may be important causes. Objectives In an effort to improve CRT response multimodality imaging (especially echocardiography, computed tomography and cardiac magnetic resonance) could play a decisive role and extensive literature has been published on the matter. However, we are so fa…
The QRS narrowing index for easy and early identification of responder to cardiac resynchronization therapy.
2013
The rationale for cardiac resynchronization therapy (CRT) in patients with heart failure (HF) is based on the possibility of inducing substantial left ventricular reverse remodeling. It is well known that some of these patients don't benefit from this therapy (the so-called non-responders) [1,2]. No better predictors of a positive answer to CRT than pre-CRT QRS duration (QRSd) were found [3,4]. The aim of our study was to identify a parameter for an easy and early identification of responders to CRT. In this regard, according to Rickard et al., we identified and observed QRS index (QI), as an expression of electrical remodeling after CRT, and its relation with anatomic reverse remodeling, e…
Observation of the rare decay K-S -> pi(0)e(+)e(-)
2003
A search for the decay Ks->pi0e+e- has been made by the NA48/1 experiment at the CERN SPS accelerator. Using data collected during 89 days in 2002 with a high-intensity Ks beam, 7 events were found with a background of 0.15 events. The branching fraction BR(Ks->pi0e+e-, m(ee) > 0.165 GeV/c^2) = (3.0^{+1.5}_{-1.2}(stat) +/-0.2 (syst)) x 10^{-9} has been measured. Using a vector matrix element and a form factor equal to one, the measurement gives BR(Ks->pi0e+e-) = (5.8^{+2.9}_{-2.4}) x 10^{-9}.
Observation of the decay KS→π+π−e+e−
2000
Abstract We present the first observation of the decay KS→π+π−e+e− based upon the data collected in 1998 by the NA48 experiment at CERN. We have identified a clean sample of 56 events with negligible background contamination. Using KL→π+π−π0D decays as normalization sample, the branching ratio is measured to be BR(KS→π+π−e+e−)=[4.5±0.7(stat)±0.4(syst)]×10−5. This result is in good agreement with the theoretical expectations from the mechanism of inner bremsstrahlung.
Existence of optimal transport maps in very strict CD(K,∞) -spaces
2018
We introduce a more restrictive version of the strict CD(K,∞) -condition, the so-called very strict CD(K,∞) -condition, and show the existence of optimal maps in very strict CD(K,∞) -spaces despite the possible lack of uniqueness of optimal plans. peerReviewed
