Estado Confusional Agudo após Corticoterapia Inalada

Background: The connection between corticotherapy and neuropsychiatric symptoms is widely known, being one of the first questions we need to assess when presenting with first episode psychiatric symptoms or confusional state. Aims: To date, data on cases related to inhaled corticotherapy and neuropsychiatric effects is scarce. In this paper we describe a rare case in a young woman. Methods: The clinical case presented led us to try to understand the data published on the subject in order to discuss it in greater length. Results and Conclusions: We present and discuss a 27-year-old patient’s case, with no previous psychiatric disease, who was admitted to our Psychiatric ward after the onset of severe acute behavioural disturbance characterized by aggressiveness, visual and auditory hallucinatory activity, misidentification and altered conscience status. It was later found that seven days earlier she had been prescribed inhaled corticotherapy for a minor respiratory infection. A few days after corticotherapy withdrawal, the clinical symptoms improved significantly.info:eu-repo/semantics/publishedVersio

Expansão para oeste do peixe-gato-europeu Silurus glanis no rio Douro (Portugal)

The current study reports the first occurrence and the spread of the European catfish Silurus glanis (Family: Siluridae) in the Portuguese section of the Douro River, suggesting a potential expansion of its distribution in Portugal either via westward dispersal across international rivers and/or human-assisted introductions into new reservoirs and drainages. The European catfish has unique features (e.g., opportunistic predator, hunting, and aggregation behaviour) that make it highly suitable for establishing self-sustaining populations in new areas and likely contribute to its invasion success. The species may severely affect native prey communities and modify food web structure and ecosystem functioning. Efficient and sustainable management actions are needed to prevent further introductions in the future.O presente estudo relata a primeira ocorrência do peixe-gato-europeu Silurus glanis (Família: Siluridae) no troço português do rio Douro, sugerindo uma potencial expansão da sua distribuição em Portugal através da dispersão natural da espécie para oeste através deste rio internacional e/ou através de introduções realizadas pelo homem em novas albufeiras. As características particulares do peixe-gato europeu (por exemplo, predador oportunista e comportamento de caça em grupo) aumentam quer o sucesso da sua dispersão quer o estabelecimento de populações auto-sustentáveis em novas massas de água. Esta espécie pode afetar severamente as comunidades de presas nativas e pode modificar a estrutura da teia alimentar, assim como mudar o funcionamento dos ecossistemas. Desta forma são necessárias ações de gestão eficazes para evitar novas introduções desta espécie.FCTinfo:eu-repo/semantics/publishedVersio

Solitons in systems of coupled scalar fields

We present a method to obtain soliton solutions to relativistic system of coupled scalar fields. This is done by examining the energy associated to static field configurations. In this case we derive a set of first-order differential equations that solve the equations of motion when the energy saturates its lower bound. To illustrate the general results, we investigate some systems described by polynomial interactions in the coupled fields.Comment: RevTex4, 5 page

Chemical abundances for the transiting planet host stars OGLE-TR-10, 56, 111, 113, 132 and TrES-1. Abundances in different galactic populations

We used the UVES spectrograph (VLT-UT2 telescope) to obtain high-resolution spectra of 6 stars hosting transiting planets, namely for OGLE-TR-10, 56, 111, 113, 132 and TrES-1. The spectra are now used to derive and discuss the chemical abundances for C, O, Na, Mg, Al, Si, S, Ca, Sc, Ti, V, Cr, Mn, Co, Ni, Cu and Zn. Abundances were derived in LTE, using 1-D plane-parallel Kurucz model atmospheres. For S, Zn and Cu we used a spectral synthesis procedure, while for the remaining cases the abundances were derived from measurements of line-equivalent widths. The resulting abundances are compared with those found for stars in the solar neighborhood. Distances and galactic coordinates are estimated for the stars. We conclude that besides being particularly metal-rich, with small possible exceptions OGLE-TR-10, 56, 111, 113, 132 and TrES-1 are chemically undistinguishable from the field (thin disk) stars regarding their [X/Fe] abundances. This is particularly relevant for the most distant of the targets, located at up to ~2 Kpc from the Sun. We also did not find any correlation between the abundances and the condensation temperature of the elements, an evidence that strong accretion of planetary-like material, tentatively connected to planetary migration, did not occur.Comment: Accepted for publication in Astronomy & Astrophysics (June 2006

Conservation of Orbital Angular Momentum in Stimulated Down-Conversion

We report on an experiment demonstrating the conservation of orbital angular momentum in stimulated down-conversion. The orbital angular momentum is not transferred to the individual beams of the spontaneous down-conversion, but it is conserved when twin photons are taken individually. We observe the conservation law for an individual beam of the down-conversion through cavity-free stimulated emission.Comment: Submitted for publication in Phys. Rev. Let

Spherical f-tilings by two non congruent classes of isosceles triangles - I

The theory of f-tilings is related to the theory of isometric foldings, initiated by S. Robertson [8] in 1977. The study of dihedral f-tilings of the Euclidean sphere $S^2$ by triangles and r-sided regular polygons was initiated in 2004, where the case r=4$was considered [4]. In a subsequent paper [1], the study of all spherical f-tilings by triangles and r-sided regular polygons, for any$rge 5$, was described. Recently, in [2] and [3] a classification of all triangular dihedral spherical f-tilings for which one of the prototiles is an equilateral triangle is given. In this paper, we extend these results considering the dihedral case of two non congruent isosceles triangles in a particular way of adjacency ending up to a class of$f$-tilings composed by three parametrised families, denoted by$mathcal{F}_{k, alpha}$,$mathcal{E}_{alpha}$and$mathcal{L}_{k}, ; kgeq 3, ; alpha>frac{pi}{2}$, respectively, and one isolated tiling, denoted by$mathcal{G}$. The combinatorial structure including the symmetry group of each tiling is also given. Dawson and Doyle in [6], [7] have also been working on spherical tilings, relaxing the edge to edge condition

Efficacy of Percutaneous Transluminal Angioplasty on Dysfunctional Fistulae Because of Inflow Stenosis

PURPOSE: Autogenous fistulas are the preferential vascular access for hemodialysis. The aim of this retrospective study was to determine the efficacy of angioplasty for dysfunctional fistulas because of inflow dysfunction. 
 METHODS: We reviewed all the angiographic procedures performed on our institution between April 2007 and April 2009. Procedures performed in dysfunctional fistulas because of inflow stenoses were analyzed. Fistulas with stenoses out of these areas were excluded. The following data were collected: patient age and sex, fistula age at the time of intervention, location of fistula, number and location of stenosis, angiography referral criteria, clinical findings (presence or absence of thrills, bruits and pulsatility) and date of reintervention or failure. 
 RESULTS: During the study period 215 fistulas were submitted to angiography of which, seventy-one presented inflow stenosis (33%). Mean follow-up was 21.72±9.26 months, and average age was 7.03 months. Two groups were considered: 31 fistulas comprising ≤6 months old, and 40 fistulas >6 months old. Primary patency rates±SE for older fistulas at 6, 12, 18 and 24 months, respectively, was 91.3%± 0.04%, 80.7%± 0.07%, 53.8% ±0.10% and 34.2±0.1% versus 91.7±0.08%, 57.1±0.14%, 23±0.14%, 11.4%± 0.1% for younger fistulas (P=0.04). Fistulas ≤6 months old and multiple stenosis were associated with a poorer primary patency rate (P=0.005).
 CONCLUSIONS: Inflow stenosis is frequently associated with fistula dysfunction. In this study we only analyzed AVF with inflow stenosis and we have shown that angioplasty can have great patency results, particularly for single lesions in matured fistulas.info:eu-repo/semantics/publishedVersio
