Approccio integrato tra il trattamento riabilitativo e farmacologico nella frozen shoulder

2007

La struttura del complesso anatomico della spalla è caratterizzata da un'ampia escursione articolare. LA nostra esperienza si è basata su uno studio preliminare di 21 pazienti; tutti prsentavano una stadiaizone di patologia di grado lieve/ moderata. Dall'analisi dei dati si evince come il trattamento combinato farmacologico/ riabilitativo possa fornire risultati migliori rispetto al solo trattamento farmacologico.

Rateless Codes Performance Analysis in Correlated Channel Model for GEO Free Space Optics Downlinks

2012

Settore ING-INF/03 - TelecomunicazioniFree Space Optics (FSO) technologies for satellite communications offer several advantages: wide bandwidth high rate capability immunity to electromagnetic interference and small equipment size. Thus they are suitable for inter-satellite links deep space communications and also for high data rate ground-to-satellite/satellite-to-ground communications. Nevertheless FSO links suffer impairments that cause power signal degradation at the receiver. Scattering and absorption cause power signal attenuations predictable by suitable deterministic models. Optical turbulence causes random irradiance fluctuations which can generate signal fading events and can thereby only be predicted by statistical models. Attenuation and fading events can corrupt FSO links and so it would be recommended to add mitigation error codes on the communication link. FSO channel can be described as an erasure channel: fading events can cause erasure errors. We have identified in rateless codes (RCs) a suitable solution to be employed in FSO links. RCs do not need feedback and they add a redundant coding on the source data that allows the receiver to recover the whole payload despite erasure errors. We implemented two different of rateless codes: Luby Transform (LT) and Raptor. We analyzed their performances on a simulated turbulent GEO FSO downlink (1 Gbps - OOK modulation) at a 106 μm wavelength and for different values of zenith angles. Assuming a plane-wave propagation and employing Hufnagel-Valley we modeled the downlink using: 1) a temporal correlated channel model based on Gamma-Gamma probability distribution and 2) an irradiance covariance function that we converted on a time function using Taylor frozen eddies hypothesis. Our new channel model is able to simulate irradiance fluctuations at different turbulence conditions as it will be shown in the full paper. We will also report performance results of LT and Raptor codes at overhead range varying between 0 and 50% and for different values of source packets.Settore ING-INF/01 - Elettronica

Blood Component Therapy and Coagulopathy in Trauma: A Systematic Review of the Literature from the Trauma Update Group

2016

Background Traumatic coagulopathy is thought to increase mortality and its treatment to reduce preventable deaths. However, there is still uncertainty in this field, and available literature results may have been overestimated. Methods We searched the MEDLINE database using the PubMed platform. We formulated four queries investigating the prognostic weight of traumatic coagulopathy defined according to conventional laboratory testing, and the effectiveness in reducing mortality of three different treatments aimed at contrasting coagulopathy (high fresh frozen plasma/packed red blood cells ratios, fibrinogen, and tranexamic acid administration). Randomized controlled trials were selected alo…

Tranexamic acid in cardiac surgery: Are low doses enough?

2020

OBJECTIVES Tranexamic acid is used to prevent hyperfibrinolysis and reduce postoperative bleeding and blood transfusions in on-pump cardiac surgery. We evaluate the efficacy of low or high dose tranexamic acid in a prospective cohort study conducted in Valencia. MATERIALS AND METHODS A total of 427 patients were recruited between January 2019 and January 2020, 207 in the Hospital General Universitario (low dose [LD]) and 220 in the Hospital Universitario y Politecnico La Fe (high dose [HD] and intermediate dose [ID]). We recorded the presence of hyperfibrinolysis on rotational thromboelastometry, intra- and postoperative administration of blood products, chest tube output within the first 1…

Management of the Sponataneous Bleeding Episodes in Factor VII Deficiency. A Prospective Evaluation of the STER,

2011

Abstract Abstract 3368 Introduction Patients with an inherited factor VII (FVII) deficiency may display a wide range of clinical phenotypes, from an asymptomatic condition to serious hemorrhagic episodes such as fatal central nervous system (CNS) or gastrointestinal (GI) bleeds (Mariani G et al. Thromb Haemost 2005; 93: 481–7). Symptomatic patients can be divided into two major categories: those with mild-to-moderate bleeding tendency and individuals with a severe bleeding tendency which may be more severe than that in hemophilia. The former group mainly experience mucosal bleeding, a clinical picture that mimics that of a platelet disorder and often does not call for treatment. In contrast…

Pediatric non-red cell blood product transfusion practices: what's the evidence to guide transfusion of the ‘yellow’ blood products?

2020

Purpose of review Research studies pertaining to the management of pediatric non-red cell blood product transfusion is limited. Clinical practices vary within disciplines and regions. Anesthesiologists need evidence-based guidelines to make appropriate and safe decisions regarding transfusion of the 'yellow' blood products for pediatric patients. Recent findings This review outlines clinical indications for transfusion of fresh frozen plasma, cryoprecipitate, platelets, and fibrinogen concentrate in pediatrics. Recent studies of non-red blood cell transfusions in critical, but stable situations are highlighted. Recommendations to guide transfusion of the 'yellow' blood products in operative…

Thrombotic Thrombocytopenic Purpura: Pathophysiology, Diagnosis, and Management

2021

Thrombotic thrombocytopenic purpura (TTP) is a rare thrombotic microangiopathy characterized by microangiopathic hemolytic anemia, severe thrombocytopenia, and ischemic end organ injury due to microvascular platelet-rich thrombi. TTP results from a severe deficiency of the specific von Willebrand factor (VWF)-cleaving protease, ADAMTS13 (a disintegrin and metalloprotease with thrombospondin type 1 repeats, member 13). ADAMTS13 deficiency is most commonly acquired due to anti-ADAMTS13 autoantibodies. It can also be inherited in the congenital form as a result of biallelic mutations in the ADAMTS13 gene. In adults, the condition is most often immune-mediated (iTTP) whereas congenital TTP (cTT…

Bleeding in Uremia

2021

Progressive deterioration of renal function eventually leads to uremia, which is associated with impaired function of platelets and a disturbed platelet–vessel wall interaction thus increasing the risk of bleeding in patients with renal failure. Furthermore, also anemia and anticoagulants/antiplatelet drugs contribute to the increased risk of bleeding in patients with end stage renal disease. Management of bleeding episodes in uremic patients includes an adequate dialysis, the correction of anemia with erythropoietin or erythropoetin stimulating agents, the administration of estrogens, desmopressin, fresh frozen plasma, cryoprecipitate, factor VIIa, or tranexamic acid. In severe bleeding ep…

The Spatial Extent of Pain Is Associated with Pain Intensity, Catastrophizing and Some Measures of Central Sensitization in People with Frozen Should…

2021

The aim of this cross-sectional study was to explore the spatial extent of pain and its association with clinical symptoms, psychological features, and pain sensitization in people with frozen shoulder (FS). Forty-eight individuals with FS completed pain drawings (PDs) and reported their clinical symptoms including pain intensity (Visual Analogue Scale) and shoulder disability (Shoulder Pain and Disability Index). Moreover, pain sensitization measurements (pressure pain thresholds, temporal summation, conditioned pain modulation, and Central Sensitization Inventory (CSI)) were assessed. Psychological features were assessed by Pain Catastrophizing Scale (PCS) and Pain Vigilance and Awareness…
