Mastopatía fibroquística

La malaltia fibroquística de la mamella o mastopatia fibroquística és un terme vague que pretén definir clínicament una síndrome constituïda per una nodularitat mamària palpable poc delimitada, d'extensió diversa, freqüentment bilateral i acompanyada de mastàlgia, particularment evident en el període premenstrual. En aquest context es tracta, per tant, d'un diagnòstic clínic, i és la malaltia benigna més freqüent de la mamella. Sovint, es presenta com un problema difícil de resoldre definitivament, amb tendència a la cronicitat, i que amb més o menys severitat es presenta en el 50 % de dones en edat reproductiva. Cal tenir en compte que la nodularitat palpable pot atribuir-se, en diversa mesura, a un procés fisiològic condicionat hormonalment. Si es considera com una malaltia o com un canvi fisiològic és un debat que solament es pot resoldre en cada cas individual, mitjançant l'aplicació de determinades exploracions auxiliars, i el diagnòstic de benignitat, amb absoluta certesa, depèn de l'estudi histològic

The Best-or-Worst and the Postdoc problems

We consider two variants of the secretary problem, the\emph{ Best-or-Worst} and the \emph{Postdoc} problems, which are closely related. First, we prove that both variants, in their standard form with binary payoff 1 or 0, share the same optimal stopping rule. We also consider additional cost/perquisites depending on the number of interviewed candidates. In these situations the optimal strategies are very different. Finally, we also focus on the Best-or-Worst variant with different payments depending on whether the selected candidate is the best or the worst

A potential record of a procolophonid parareptile from the Triassic of the Iberian Peninsula

Cranial and postcranial remains from the Middle Triassic of the Northeastern part of the Iberian Peninsula are reported and tentatively assigned to Procolophonidae. The finding is the first occurrence of a procolophonid parareptile in the Iberian Peninsula, representing the southernmost record of the group in Europe. The fossilbearing locality is dated as Anisian (Middle Triassic) and includes three tooth-bearing bones, two cranial bone fragments and one interclavicle. The mandible described herein includes nine teeth. No cusps or complete crowns are preserved, but sections of the teeth are available. The three anterior teeth progressively decrease in size from front to back, whereas the teeth from the fourth to the eighth position present the opposite trend. The last tooth (the ninth) is clearly reduced in comparison to the previous ones. A close relationship with Anomoiodon-Kapes is suggested, however, more material is required in order to assess the exact taxonomical determination of the Iberian remains. This finding is expected to shed some light on the geographical distribution of procolophonines

Unidad de diagnóstico rápido (UDR) en patología tumoral

Objetivos: Desarrollar una UDR, vinculada al Servicio de Urgencias Hospitalario (SUH), proporcionando prioridad en el radiodiagnóstico y mayor accesibilidad a las consultas de especializada, supone un abordaje de la patología tumoral más dinámico. Nuestro objetivo fue analizar el impacto de la UDR en el manejo de dicha patología. Metodología: Estudio descriptivo, retrospectivo, de base poblacional, realizado en la Clínica USP-Palmaplanas, hospital de 150 camas Analizando el manejo del total de pacientes con tumores atendidos en la UDR desde abril 2006 a marzo 2008. Se utilizaron los indicadores de actividad y calidad creados para dicho fin. Resultados: Total pacientes atendidos en la UDR 2473, total pacientes con diagnóstico de patología tumoral 73. Tiempo de espera desde su atención en el SUH hasta valoración en la UDR (<48h 41%, 2-4 días 36%), tiempo de espera desde atención inicial- final en las UDR (mismo día 17%, <8 días 64%), tiempo de espera desde alta UDR hasta su atención para el abordaje terapéutico (<48h en el 91%), se cursaron 11 ingresos hospitalarios tras el diagnóstico desde la UDR. Conclusiones: La UDR permite agilizar el diagnóstico y tratamiento precoces de la patología tumoral, mejorando claramente la eficiencia y la seguridad con una reducción en la estancia media hospitalaria y en la carga emocional del paciente.Objectives: The implementation of a Hospital Emergency Unit based RDU in order to prioritise diagnostic imaging and the access to specialised outpatient clinics, has dynamized the management of patients first diagnosed with cancer. Our objective was to analyze the impact of an RDU in the management of this group of patients. Methods: Descriptive, retrospective study of the population seen at USP Palmaplanas Clinic, a 150 bed hospital, which analyses the management of patients seen in the RDU from April 2006 to March 2008. Activity and quality indicators were created to support this study. Results: Total number of patients seen in the RDU: 2473. 73 of these patients were diagnosed with possible cancer. Waiting times to be seen in RDU from the Emergency Unit: <48 hours in 41% of the cases, 2-4 days in 36%. Waiting times from first visit at RDU to last visit: same day in 17%, <8 days in 64%. Waiting times from first visit to RDU to treatment: <48 hours in 91% of the cases. 11 patients were admitted to hospital for management. Discussion: RDU allows a dynamic management of patients with cancer, from first diagnosis to early treatment, improving patient care, efficiency and safety. It also reduces hospital stay and reduces patients’ emotional distress

The intervals method : a new approach to analyse finite element outputs using multivariate statistics

Background. In this paper, we propose a new method, named the intervals' method, to analyse data from finite element models in a comparative multivariate framework. As a case study, several armadillo mandibles are analysed, showing that the proposed method is useful to distinguish and characterise biomechanical differences related to diet/ecomorphology. - Methods. The intervals' method consists of generating a set of variables, each one defined by an interval of stress values. Each variable is expressed as a percentage of the area of the mandible occupied by those stress values. Afterwards these newly generated variables can be analysed using multivariate methods. - Results. Applying this novel method to the biological case study of whether armadillo mandibles differ according to dietary groups, we show that the intervals' method is a powerful tool to characterize biomechanical performance and how this relates to different diets. This allows us to positively discriminate between specialist and generalist species. - Discussion. We show that the proposed approach is a useful methodology not affected by the characteristics of the finite element mesh. Additionally, the positive discriminating results obtained when analysing a difficult case study suggest that the proposed method could be a very useful tool for comparative studies in finite element analysis using multivariate statistical approaches

Nuevos enfoques sobre los vertebrados del Pérmico y Triásico de la Península Ibérica, con énfasis en las cuencas Pirenaica y Catalana

Few studies paid attention to the Permian and Triassic vertebrates from the Iberian Peninsula and a re-evaluation of these faunas is needed in order to compare them with other European basins. As a first step, we present here the available data from the Catalonian and Pyrenean basins (NE of the Iberian Peninsula), offering new insights on the diversity and temporal distribution of their vertebrate faunas. The two basins have yielded unexpectedly abundant and diverse vertebrate assemblages, including fishes, amphibians and reptiles from continental and marine environments. The revision of classical finds and the analysis of new material provide data towards an understanding of the evolutionary and palaebiogeographical history of the Permian and Triassic vertebrate Iberian faunas. Permian remains mainly correspond to footprints recovered from alluvial deposits; the osteological record is scarce in the Iberian Peninsula. Early Triassic vertebrate localities are unknown. Middle Triassic faunas are abundant and reflect the change from continental environments to a wide diversity of coastal and marine depositional environments. During the Anisian, faunas are represented by footprints and skeletal remains of amphibians (capitosaurs) and terrestrial reptiles (archosauromorphs and procolophonoids). Ichthyofauna, sauropterygians, thalattosaurs and protorosaurians are known through the late Anisian and Ladinian. Finally, Late Triassic localities representing coastal environments have also yielded marine reptiles (sauropterygians) and a diverse ichthyofauna.Se han realizado hasta el momento pocos estudios de los vertebrados del Pérmico y el Triásico de la Península Ibérica y por este motivo, una re-evaluación de estas faunas es necesaria para compararlas con las halladas en otras cuencas europeas. Como primer paso, aquí presentamos la información disponible de las cuencas Catalana y Pirenaica (NE de la Península Ibérica), ofreciendo nuevos puntos de vista sobre la diversidad y distribución temporal de las faunas de vertebrados. Las dos cuencas muestran una inesperada abundancia y diversidad de faunas de vertebrados, incluyendo peces, anfibios y reptiles de ambientes continentales y marinos. La revisión de hallazgos clásicos y el análisis de nuevo material proporcionan nuevos datos para la comprensión de la historia evolutiva y paleobiogeográfica de las faunas de vertebrados durante el Pérmico y el Triásico en la Península Ibérica. Los hallazgos en el Pérmico corresponden mayoritariamente a pisadas encontradas en depósitos aluviales, siendo el registro osteológico muy escaso en la Península Ibérica. Se desconocen localidades de vertebrados del Triásico inferior. Las faunas del Triásico medio son abundantes y reflejan el cambio desde ambientes continentales hasta una amplia diversidad de ambientes deposicionales costeros y marinos. Durante el Anisiense, las faunas están representadas por pisadas y restos esqueléticos de anfibios (capitosaurios) y reptiles terrestres (arcosauriformes y procolofonoideos). De finales del Anisiense y el Ladiniense se conoce ictiofauna, sauropterigios, talattosaurios y protorosaurios. Finalmente, las localidades del Triásico superior están representadas por ambientes costeros conservando reptiles marinos (sauropterigios) y una diversa ictiofauna
