Hiatal herniation of the stomach and pancreas in a patient with oxygen desaturations
2013
Hiatal hernia (HH), a neglected cause of cardiorespiratory symptoms, is a frequent entity characterized by the displacement of the gastro- esophageal junction and part of the stomach into the mediastinum. Although often asymptomatic, HH may also exert a wide spectrum of clinical presentations due to cardio-pulmonary compression, including acute cardiovascular events such as arrhythmias, post-prandial syncope, angina-like chest pain, recurrent acute heart failure, hemodynamic collapse, electrocardiographic changes (T-wave inversion, ST elevation) simulating myocardial ischemia or pericarditis, and respiratory manifestations that can range from exercise intolerance and dyspnea on exertion to …
Ergebnisse der bilateralen Operationstechnik bei primärem Hyperparathyreoidismus
2001
AIM OF THE STUDY The surgical success rate and clinical outcome after surgery for primary hyperparathyroidism were evaluated in a prospective long-term follow-up study. PATIENTS AND METHODS 407 patients, 396 with the first manifestation, 6 with recurrent and 5 with persistent disease underwent operation from August 1, 1987 to August 15, 1999. All patients were prospectively investigated in a long-term follow-up study and underwent reexaminations at regular surveillance intervals. The postoperative course is known in 93.9% of all patients. RESULTS The prevalence of asymptomatic primary hyperparathyroidism was 5.6% in our patients. Surgical cure was obtained in 97.7% of patients after initial…
Optimal interventional treatment in a patient with occlusion of the brachiocephalic trunk and left subclavian artery with “double” steal syndrome
2015
Subclavian steal syndrome, which comprises reversal of flow in the ipsilateral vertebral artery with stenosis or occlusion of the subclavian artery (SA) or brachiocephalic trunk (BCT), was first described by Contorni in 1960 [1]. This clinical syndrome manifests with the signs and symptoms of vertebrobasilar insufficiency, but can also be asymptomatic. This paper describes a step-by-step technique of complex endovascular treatment for a double steal syndrome caused by occlusions of the BCT and the left SA, associated with stenosis of the left internal carotid artery (ICA) and reversed flow in the left external carotid artery (ECA).
Asymptomatic Bone Cement Pulmonary Embolism after Vertebroplasty: Case Report and Literature Review
2013
Introduction. Acrylic cement pulmonary embolism is a potentially serious complication following vertebroplasty. Case Report. A 70-year-old male patient was treated with percutaneous vertebroplasty for osteoporotic nontraumatic vertebral collapse of L5-S1. Asymptomatic pulmonary cement embolism was detected on routine postoperative chest radiogram and the patient was treated with enoxaparin, amoxicillin, and dexamethasone. At the followup CT scan no further migration of any cement material was reported; and the course was uneventful. Discussion. The frequency of local leakage of bone cement is relatively high (about 80–90%), moreover, the rate of cement leakage into the perivertebral veins (…
Safety and efficacy of endovascular treatment for carotid artery stenoses using proximal protection systems : 30-day follow-up
2017
Introduction. Although surgical endarterectomy remains the treatment of choice for carotid artery stenosis, carotid artery stenting (CAS) with use of proximal protection systems (PPS) plays an important role as alternative treatment modality, especially in high risk patients. This study was aimed at the assessment of safety of CAS with use of the PPS and also at identification of risk factors associated with this procedure. Material and methods. This was a post hoc analysis, with 30-day follow-up. We analysed results of treatment of 94 patients who underwent 97 CAS with PPS, 47 such procedures in asymptomatic, and 50 in symptomatic individuals. Results. There were 0 strokes during 30-day fo…
The Role of Asymptomatic Individuals in the COVID-19 Pandemic <i>via</i> Complex Networks
2020
Background: Recent seroprevalence studies have tried to estimate the real number of asymptomatic cases affected by COVID-19. It is of paramount importance to understand the impact of these infections in order to prevent a second wave. This study aims to model the interactions in the population by means of a complex network and to shed some light on the effectiveness of localised control measures in Italy in relation to the school opening in mid-September.} Methods: The formulation of an epidemiological predictive model is given: the advantage of using this model lies in that it discriminates between asymptomatic and symptomatic cases of COVID-19 as the interactions with these two categorie…
Consensus recommendations for managing asymptomatic persistent non-virus non-alcohol related elevation of aminotransferase levels
2008
Abstract A persistent increase in non-virus non-alcohol related aminostransferase levels can have multiple causes, which differ in terms of prevalence and clinical importance. In the general population, the most frequent cause is non-alcoholic hepatic steatosis, which can evolve into steato-hepatitis and cirrhosis. The treatment for steatosis and non-alcoholic steato-hepatitis consists of modifying lifestyles, whereas the effectiveness of drug treatment remains to be determined. Other much less frequent (yet not rare) causes of persistent non-virus non-alcohol related elevations in aminotransferase levels are celiac disease and hemochromatosis, whereas autoimmune hepatitis, primary biliary …
Should We Screen for <i>Helicobacter pylori</i> to Prevent Gastric Cancer?
2007
Although the strategy for <i>Helicobacter pylori</i> infection management is well defined and quite well followed in a number of situations, including peptic ulcer disease, the issue of <i>H. pylori</i> screening and eradication in the general population still remains. The following debate attempts to find the answer of whether or not <i>H. pylori</i> screening should be performed in the asymptomatic population for preventing gastric cancer. As yet, there is no final evidence-based consensus about the need to screen for <i>H. pylori</i> in order to decrease the incidence of gastric cancer.
Radiological Follow-Up of Inflammatory Bowel Diseases
2015
Inflammatory bowel diseases (IBD) are chronic gastrointestinal diseases that typically affect the young working-age population. Patients with IBD, both asymptomatic and symptomatic, often develop complications during their clinical course. This is particularly true in patients with Crohnâs disease (CD) and biological signs of inflammation, despite being asymptomatic. In addition, it seems clear that the absence of symptoms does not imply an absence of inflammation. For all the above mentioned reasons, patients should be followed up and objectively evaluated. IBD are idiopathic diseases characterized by periods of remission and frequent exacerbations. To appreciate the impact of disease pr…
Subclinical atherosclerosis: independent predictor of cardiovascular events in a 20-years follow up of patients with or without metabolic syndrome
2013
Purpose: To evaluate the influence of carotid atherosclerosis and metabolic syndrome (MetS) on the prediction of cardiovascular events during a 20-years follow-up. Methods: We studied a population of 529 asymptomatic patients, divided into 2 groups according to the results of the carotid ultrasound evaluation: one without atherosclerotic lesions (198 patients) and a second one with an increased carotid IMT or asymptomatic carotid plaque (331 patients). In each of these groups, we identified two subgroups of subjects with and without MetS. Cardiovascular endpoints were investigated in a 20-years follow-up: acute myocardial infarction, angina, transient ischemic attack, ischemic stroke, abdom…
