Sedation and analgesia during noninvasive ventilation (NIV)

2017

The use of noninvasive ventilation (NIV) has increased significantly in patients with acute respiratory failure (ARF) in order to prevent tracheal intubation and its complications. Unfortunately, NIV failure represents a frequent event, with rates that in some cases reach 40%. Mask intolerance, agitation, and delirium may lead to NIV failure, thus requiring endotracheal intubation. NIV failure rates are higher in patients without chronic obstructive pulmonary disease (COPD), and, when used in acute hypoxemic failure, its failure is associated with an increased mortality rate. The practice of sedation during NIV could be a valuable option for patients at risk of intubation. Sedation may decr…

Whole-body magnetic resonance imaging in the diagnosis and follow-up of multicentric infantile myofibromatosis: A case report

2017

Myofibromatosis is an uncommon disorder of infancy, characterized by proliferation of myofibroblasts in solitary or multiple nodules. The clinical characteristics depend on the involved sites: Myofibromatosis may develop as a musculoskeletal form, with non-painful swellings and eventual mass effect symptoms, or as a generalized form with visceral involvement and organ failure. Prognosis and therapy vary between the abovementioned patterns. When there is no visceral involvement, the tumors may regress spontaneously; however, the visceral form may represent a lifethreatening condition with poor outcome and it requires aggressive management. Imaging assessment of disease spread is mandatory to…

Lavandula angustifolia Essential Oil and Linalool Counteract Social Aversion Induced by Social Defeat

2018

Many vegetable extracts, essential oils, and their main constituents are active on the Central Nervous System (CNS). In fact, they have been used as sedatives, hypnotics, or tranquilizers for their activity in treating CNS disorders. In this research, we studied the possible activities of Lavandula angustifolia (LA) essential oil and of its main constituent, linalool, as anti-stress compounds on anxiety and social interaction and their in vitro effects on proteins (pERK and PKA) involved in the transmission of the signal. An acute intraperitoneal injection of linalool (100 mg/kg) and of LA essential oil (200 mg/kg) reduced motor activity without any anxiolytic effect, but significantly incr…

Dizziness and vertigo in a department of emergency medicine.

1995

Dizziness is a common and vexing diagnostic problem in emergency departments. The term is rather undefinite and often misused, but can in practice be classified into four categories: fainting, disequilibrium, vertigo and miscellaneous syndromes. Vertigo is the most common category of dizziness. Classification of vertigo can be based either on chronological criteria (acute, recurrent or chronic vertigo) or on topographical criteria (peripheral or central vertigo). Physicians working in emergency departments must be able to rapidly identify patients with potentially serious forms of vertigo, which could cause death or disability, and patients with mild conditions, that can be effectively trea…

Renal and hepatic integrity in long-term sevoflurane sedation using the anesthetic conserving device: A comparison with intravenous propofol sedation…

2015

Abstract Introduction Critically ill patients are sedated with intravenous agents because the use of inhaled agents is limited by their potential risk of toxicity. Increasing levels of inorganic fluorides after the metabolism of these agents have been considered potentially nephrotoxic. However, hepatic involvement after prolonged administration of sevoflurane has not yet been studied. The present study evaluated the potential renal and hepatic toxicity caused by prolonged administration (72 h) of sevoflurane. Methods For this experimental, prospective, randomized, controlled trial, 22 Landrace × Large-White female pigs were randomly assigned to two groups: intravenous propofol (P) or inhal…

Fiscalidad y manufacturas en la Valencia de Felipe V

2002

El presente texto recoge la conferencia impartida en el curso "Felipe V y los valencianos", realizado en la sede valenciana de la UIMP en julio de 2001. La revisión de los efectos que la política impulsada por el gobierno de Felipe V tuvo sobre la economía valenciana dieciochesca matiza la valoración positiva que hicieron de ella los pensadores mercantilistas más importantes del periodo. La protección otorgada a la industria sedera lesionó los intereses agrarios y acentuó el carácter tradicional de la estructura productiva, dificultando la posterior modernización del sector. Por su parte, el peculiar sistema introducido en la ciudad de Valencia para recaudar el impuesto del equivalente cond…

Per camins inussitats i sendes molt apartades. Contrabando de seda valenciana hacia Castilla durante la segunda mitad del siglo XVI

2015

Este artículo analiza la intensa corriente de contrabando de seda valenciana hacia Castilla, que se desarrolló durante la segunda mitad del siglo XVI. Entre otros factores, la creación del nou imposit de la seda en 1552 incentivó esta actividad ilícita, que llegó a convertirse en un modo de vida en las principales regiones productoras (especialmente la Ribera del Júcar) y un motivo constante de litigio para las autoridades, incapaces de frenar este tráfico ilícito. La política fiscal valenciana y el auge del contrabando de seda a Toledo lastró la sedería valenciana durante esta centuria, ya que dificultó el abastecimiento de materia prima de los telares de la ciudad de Valencia. Del mismo m…

Towards understanding the abundance of non-pollen palynomorphs : A comparison of fossil algae, algal pigments and sedaDNA from temperate lake sedimen…

2018

Given the increased interest in non-pollen palynomorphs (microscopic objects other than pollen identified from pollen slides) in palaeoecological studies, it is necessary to seek a deeper understanding of the reliability of these results. We combined quantitative information of algal pigments and sedimentary ancient DNA (sedaDNA) of phylotaxonomical resolution to validate the richness and abundance of fossil algae in the sediment of a small temperate lake. For the first time, fossil and sedaDNA algae data were combined in a composite data-set and used to reconstruct algae turnover rates over the last 14,500 years. This comparison serves as both an example of howfossil algae can be used to a…
