Optical Coherence Tomography in Glaucoma

2012

Retinal nerve fiber layer (RNFL) thinning and optic nerve head cupping are key diagnostic features of glaucomatous optic neuropathy. The higher resolution of the recently introduced SD-OCT offers enhanced visualization and improved segmentation of the retinal layers, providing a higher accuracy in identification of subtle changes of the optic disc and RNFL thinning associated with glaucoma.

Effect of dietary omega-3 and omega-6 fatty acids on IOP elevation, electroretinographic changes and retinal ganglion cell loss in a rat model of gla…

2008

Purpose To test the efficacy of dietary omega-3 and omega-6 fatty acids in a rat model of glaucoma induced by laser photocoagulation. Methods Rats were fed for 3 months with a diet containing either: 1) 17% of omega-3 fatty acids (10% EPA + 7% DHA), 2) 10% of omega-6 fatty acids (as GLA), or 3) a combination of both omega-3 and omega-6 fatty acids (10% EPA + 7% DHA + 10% GLA), by comparison with a control group of animals fed with a standard diet deprived of EPA, DHA and GLA. After 3 months of diet, glaucoma was induced in one eye of the animal by laser.IOP was regularly measured and the retinal function was evaluated by electroretinography (ERG) for 3 months. At the end of the experiment, …

Does Posterior Capsule Opacification Affect the Results of Diagnostic Technologies to Evaluate the Retina and the Optic Disc?

2014

The visual outcome obtained after cataract removal may progressively decline because of posterior capsular opacification (PCO). This condition can be treated by creating an opening in the posterior lens capsule by Nd:YAG laser capsulotomy. PCO optical imperfections cause several light reflection, refraction, and diffraction phenomena, which may interfere with the functional and structural tests performed in different ocular locations for the diagnosis and follow-up of ocular disease, like macular and optic nerve diseases. Some parameters measured by visual field examinations, scanning laser polarimetry, and optical coherence tomography (OCT) have changed after PCO removal. Imaging quality a…

Chirurgische Therapie des Pulmonalarteriensarkoms

2001

BACKGROUND AND OBJECTIVES Pulmonary artery sarcoma is a rare neoplasm and possibly unnoticed cause of pulmonary hypertension. The presentation is one of central pulmonary artery obstruction and progressive right-heart failure. In most cases, the diagnosis of malignancy is confirmed post mortem. We report the outcome of eight patients with primary pulmonary artery sarcomas. METHODS Eight patients (four female, four male, mean age 48,2 years, preop. NYHA functional class III/IV: n = 5/3) were referred for further evaluation of pulmonary hypertension. Malignancy was suspected in six of these patients by means of computed tomography (CT) and magnetic resonance tomography (MRT). In two patients …

Case Report: Unusual Clinical Presentation of a Rare Cardiac Inflammatory Myofibroblastic Tumor in Children: The Differential Diagnosis With Pediatri…

2021

Introduction: There are still no guidelines about pediatric cardiac cancers. The purpose of this work is to provide new scientific data facilitating the differential diagnosis of a rare cardiac tumor with an unusual presentation, such as the cardiac inflammatory myofibroblastic tumor (IMT).Case Presentation: A 3-year-old male child presented with several symptoms including unconsciousness, vomiting, and drowsiness. A clinical and neurological examination revealed a unilateral (right) motor delay and positive unilateral Babinski sign. Electrocardiogram (ECG) was normal.Diagnostic Assessment: The total body computed tomography (CT) scans showed hypodensity in the left temporal–parietal lobe, …

Fever of unknown origin and anaemia as a form of presentation of a rhabdomyosarcoma

2011

Abstract We report a case of fever of unknown origin, in its classical presentation. A wide range of studies were unrevealing, but finally a positron emission tomography/computed tomography allowed us to establish the diagnosis of rhabdomyosarcoma in the pelvic region.

Das Pulmonalarteriensarkom - Prä- und postoperative radiologische Befunde bei der Tumorerstmanifestation und beim Rezidiv

2008

Purpose Primary pulmonary artery sarcomas are very rare tumors. Their diagnosis is difficult due to their unspecific symptoms. Still, an early preoperative diagnosis is the only possibility for a potential therapy. Patients and methods 4 pre- and 5 postoperative CT- and three pre- and one postoperative MRT-examination(s) have been evaluated with respect to surgical and histological findings. Results The presence of a convex intraluminal bulging mass spreading mostly from the pulmonary trunc continuously into the peripheral pulmonary artery branches the filling and dilatation of the vessels, the tumor's inhomogeneity indicating hemorrhages and necrosis and the appearance of intrapulmonary no…

Condylar intramedullary intraosseous lipoma : contribution of a new case and review of the literature

2017

Background Lipoma is the most common benign tumour of the human body, being intraosseous involvement very rare. Just 1 to 4% of all cases of lipoma are located in the oral cavity, only 0.1% being intraosseous. The jaw is its most uncommon bone location. Etiology of intraosseous lipoma (IOL) is unknown, although several theories have been proposed. Usually asymptomatic, the symptoms, when present, will depend on its location and size. Its origin may be intraosseous or juxtacortical. A biopsy is essential for diagnosis, and definitive treatment involves resection or curettage of the lesion. The aim of this paper is to present a new case of intramedullary intraosseous lipoma of the mandible wi…

Increased risk of angiosarcoma secondary to cancer radiotherapy: Case series and review of the treatment options.

2020

Angiosarcomas (ASs) are aggressive tumors of vascular endothelial origin, occurring sporadically or in association with prior radiotherapy or chronic lymphedema. With only 1-5% of all sarcomas, the incidence seems low, but for the affected patient due to the extremely poor prognosis and the limited treatment options, the fate is often inevitable. Radiotherapy, chemotherapy, or "target therapy" have been used in the management of AS, but represent individual case decisions without lasting evidence. Over the past few years, breast-conserving surgery followed by radiation therapy, known as breast-conserving therapy (BCT), is being employed as a standard treatment for early-stage breast cancer,…

Combined Behavioral and Mismatch Negativity Evidence for the Effects of Long-Lasting High-Definition tDCS in Disorders of Consciousness: A Pilot Study

2020

Objective: To evaluate the effects of long-term High-definition transcranial direct current stimulation (HD-tDCS) over precuneus on the level of consciousness (LOC) and the relationship between Mismatch negativity (MMN) and the LOC over the therapy period in patients with Disorders of consciousness (DOCs). Methods: We employed a with-in group repeated measures design with an anode HD-tDCS protocol (2 mA, 20 min, the precuneus) on 11 (2 vegetative state and nine minimally conscious state) patients with DOCs. MMN and Coma Recovery Scale-Revised (CRS-R) scores were measured at four time points: before the treatment of HD-tDCS (T0), after a single session of HD-tDCS (T1), after the treatment of…
