Clinical experience with retrievable vena cava filters: results of a prospective observational multicenter study

2005

Summary. Background: Retrievable inferior vena cava (IVC) filters offer the attractive possibility to be definitive or to be removed when they become unnecessary. Objective: The purpose of this study was to evaluate the efficacy and the likelihood to remove the retrievable IVC filter ALN. Methods: A total of 30 patients (13 males and 17 females, mean age 57 ± 15 years) underwent placement of ALN filters. Indications for implantation were acute venous thromboembolism (VTE) with a contraindication to anticoagulation in 26 cases (86%), primary prophylaxis after major trauma in two cases (7%) or before surgery in two patients with very high thromboembolic risk (7%). Results: The filter was succ…

Reliability of wastewater analysis for monitoring COVID-19 incidence revealed by a long-term follow-up study

2021

Background Wastewater-based epidemiology has been used for monitoring human activities and waterborne pathogens. Although wastewaters can also be used for tracking SARS-CoV-2 at the population level, the reliability of this approach remains to be established, especially for early warning of outbreaks. Methods We collected 377 samples from different treatment plants processing wastewaters of >1 million inhabitants in Valencia, Spain, between April 2020 and March 2021. Samples were cleaned, concentrated, and subjected to RT-qPCR to determine SARS-CoV-2 concentrations. These data were compared with cumulative disease notification rates over 7 and 14 day periods. Results We amplified SARS-CoV-2…

Calcification of the intracranial carotid artery and its relation to the clinical and angiographic picture: an angiographic classification of asterio…

1968

Fifty six patients with arteriosclerosis cerebri confirmed by X-rays examinations were clinically and angiographically studied. Calcifications of the carotid artery were found predominantly in human beings between the ages of 55 and 65 and more often among men than among women, the proportion being 2.5 to 1. Nearly all arteriosclerotic patients with calcium deposits in the carotid artery showed several neurological and mental deficits, the most frequent initial symptoms being motor disturbances. Angiographic anormalities found in these patients can be classed into 3 groups: (a) grade I— wavy course of the cerebral vessels, small number of peripheral brain vessels, formation of small knots, …

Cystic mass of the floor of the mouth

2018

Background Epidermoid and dermoid cysts in the oral cavity are relatively uncommon lesions of developmental origin. They often remain asymptomatic for years until they grow enough to interfere with speech, deglutition and less often with breathing which can pose a critical risk to the airway and require immediate surgery. Case description A case of an epidermoid cyst of the floor of the mouth affecting a 37-year-old man is presented; this lesion was surgically enucleated with an intraoral approach. Patient did well postoperatively and there was no evidence of recurrence up to 2 years of follow up. Clinical implications Floor of the mouth is a challenging site for the diagnosis of a broad va…

Management of Atrial Fibrillation Suppression in AF-HF Comorbidity Therapy (MASCOT) Trial

2003

Inter- [1,2], intra- [3,4], and atrioventricular [51(AV) dyssynchrony are not new concepts, but only recently have attempts been made to correct these disorders in an effort to treat heart failure (HF). A series of trials [6] has addressed partial or comprehensive cardiac resynchronization in patients with severe HF and evidence of cardiac dyssynchrony. Cardiac resynchronization should improve left ventricular (LV) performance; several trials [7-10] have demonstrated improvement in many hemodynamic parameters (LV and aortic pressure, shortening of mitral diastolic regurgitation, synchronized LV and atrial systole, LV volume, reduced myocardial oxygen consumption) and clinical end-points (qu…

Diagnosis and treatment of asymptomatic left ventricular systolic dysfunction after myocardial infarction.

2013

The increased survival after acute myocardial infarction induced an increase in heart failure with left ventricular systolic dysfunction. Early detection and treatment of asymptomatic left ventricular systolic dysfunction give the chance to improve outcomes and to reduce costs due to the management of patients with overt heart failure.

Koronare Bypassdiagnostik mit CT und MRT - eine Bestandsaufnahme

2004

The limited lifetime and the correlation between graft occlusion and recurring symptoms underline the need for repeated imaging of coronary artery bypass grafts. CT and MRI allow for non-invasive imaging of coronary bypasses with high accuracies concerning the patency of these vessels. Multidetector CT seems to be the CT technique of choice, especially after the introduction of 16 slice CT scanners for morphologic assessment of coronary artery bypass grafts. Compared with MRI, CT is a robust technique for assessment of cardiac anastomoses, native coronary arteries, and for the detection of graft stenoses. MRI, however, is able to deliver functional information about the grafts and the recip…

The pathophysiology of aging bone jaw: primary and secondary prevention

2010

The skeleton is composed of approximately 200 bones, and it is the backbone of our body along with ligaments and joints. The bone is not a static but a dynamic structure, constantly reshuffling, that may suffer fractures due to trauma, despite their particular hardness and strength. Complex physiologic mechanisms, sometimes with the help of surgery, can lead to bone repairing. In the elderly, often, the skeletal system can be affected by osteoporosis, a "silent disease" that causes fragile bones especially of the vertebrae and femur; its contributing factors are menopause (in women), smoking, nutritional deficiencies, systemic diseases or prolonged use of drugs. The masticatory apparatus an…

Diabetes and Dementia

2015

Persons with type 2 diabetes mellitus (DM2) have an increased incidence of cognitive decline and dementia. An increased cortical and subcortical atrophy has been found after controlling for vascular disease and inadequate cerebral circulation. A possible role of insulin resistance and hyperinsulinemia has been suggested to mediate the link between DM2 and Alzheimer’s Disease (AD). Altered insulin signaling may contribute to AD biochemical and histopathological lesions. Both hyperglycemia and hypoglycemia may contribute to cognitive decline in DM2. Recurrent symptomatic and asymptomatic hypoglycemic episodes have been suggested to cause subclinical brain damage, and permanent cognitive impai…
