  1. Intrusion of basaltic magma into a crystallizing granitic magma chamber: The Cordillera del Paine pluton in southern Chile

    Michael, Peter J.

    The Cordillera del Paine pluton in the southernmost Andes of Chile represents a deeply dissected magma chamber where mafic magma intruded into crystallizing granitic magma. Throughout much of the 10x15 km pluton, there is a sharp and continuous boundary at a remarkably constant elevation of 1,100 m that separates granitic rocks (Cordillera del Paine or CP granite: 69 77% SiO2) which make up the upper levels of the pluton from mafic and comingled rocks (Paine Mafic Complex or PMC: 45 60% SiO2) which dominate the lower exposures of the pluton. Chilled, crenulate, disrupted contacts of mafic rock against granite demonstrate that partly crystallized granite was intruded by mafic magma which solidified prior to complete crystallization of the granitic magma. The boundary at 1,100 m was a large and stable density contrast between the denser, hotter mafic magma and cooler granitic magma. The granitic magma was more solidified near the margins of the chamber when mafic intrusion occurred, and the PMC is less disrupted by granites there. Near the pluton margins, the PMC grades upward irregularly from cumulate gabbros to monzodiorites. Mafic magma differentiated largely by fractional crystallization as indicated by the presence of cumulate rocks and by the low levels of compatible elements in most PMC rocks. The compositional gap between the PMC and CP granite indicates that mixing (blending) of granitic magma into the mafic magma was less important, although it is apparent from mineral assemblages in mafic rocks. Granitic magma may have incorporated small amounts of mafic liquid that had evolved to >60% SiO2 by crystallization. Mixing was inhibited by the extent of crystallization of the granite, and by the thermal contrast and the stable density contrast between the magmas. PMC gabbros display disequilibrium mineral assemblages including early formed zoned olivine (with orthopyroxene coronas), clinopyroxene, calcic plagioclase and paragasite and later-formed amphibole

    The timing, structure and termination of the last southern mountain glaciation and its forcing remains unclear. Most studies have focused on the global Last Glacial Maximum (LGM; 26.5-19 ka) time period, which is just part of the extensive time-frame within the last glacial period, including Marine Isotope Stages 3 and 4. Understanding the glacial fluctuations throughout the glacial period is a prerequisite for uncovering the cause and climate mechanism driving southern glaciation and the interhemispheric linkages of climate change. Here, we present an extensive (n = 65) cosmogenic 10Be glacier chronology derived from moraine belts marking the pre-global LGM extent of the former Patagonian Ice Sheet in southernmost South America. Our results show the mountain ice sheet reached its maximum extent at 48.0 ± 1.8 ka during the local LGM, but attained just half this extent at 21.5 ± 1.8 ka during the global LGM. This finding, supported by nearby glacier chronologies, indicates that at orbital time scales, the southern mid-latitude glaciers fluctuated out-of-phase with northern hemisphere ice sheets. At millennial time-scales, our data suggest that Patagonian and New Zealand glaciers advanced in unison with cold Antarctic stadials and reductions in Southern Ocean sea surface temperatures. This implies a southern middle latitudes-wide millennial rhythm of climate change throughout the last glacial period linked to the north Atlantic by the bipolar seesaw. We suggest that winter insolation, acting alongside other drivers such as the strength and/or position of the southern westerlies, controlled the extents of major southern mountain glaciers such as those in southernmost South America.

    The subduction system in southern Patagonia provides direct evidence for the variability of the position of an active continental arc with respect to the subducting plate through time, but the consequences on the arc magmatic record are less well studied. Here we present a geochemical and geochronological study on small plutons and dykes from the upper crust of the southern Patagonian Andes at 51°S, which formed as a result of the subduction of the Nazca and Antarctic plates beneath the South American continent. In situ U-Pb geochronology on zircons and bulk rock geochemical data of plutonic and dyke rocks are used to constrain the magmatic evolution of the retro-arc over the last 30 Ma. We demonstrate that these combined U-Pb and geochemical data for magmatic rocks track the temporal and spatial migration of the active arc, and associated retro-arc magmatism. Our dataset indicates that the rear-arc area is characterized by small volumes of alkaline basaltic magmas at 29-30 Ma that are characterized by low La/Nb and Th/Nb ratios with negligible arc signatures. Subsequent progressive eastward migration of the active arc culminated with the emplacement of calc-alkaline plutons and dikes 17-16 Ma with elevated La/Nb and Th/Nb ratios and typical subduction signatures constraining the easternmost position of the southern Patagonian batholith at that time. Geochemical data on the post-16 Ma igneous rocks including the Torres del Paine laccolith indicate an evolution to transitional K-rich calc-alkaline magmatism at 12.5 ± 0.2 Ma. We show that trace element ratios such as Nb/Ta and Dy/Yb systematically decrease with increasing SiO2, for both the 17-16 Ma calc-alkaline and the 12-13 Ma K-rich transitional magmatism. In contrast, Th/Nb and La/Nb monitor the changes in the source composition of these magmas. We suggest that the transition from the common calc-alkaline to K-rich transitional magmatism involves a change in the source component, while the trace element ratios

    The upper crustal bimodal Torres del Paine Intrusion, southern Chile, consists of the lower Paine-Mafic- Complex and the upper Paine-Granite. Geochronologically this bimodal complex is not well studied except for a few existing data from Halpern (1973) and Sanchez (2006). The aim of this study is to supplement the existing data and to constrain the age relations between the major magmatic pulses by applying high precision U-Pb dating on accessory zircons and 40Ar/39Ar-laser-step-heating-ages on biotites from the Torres del Paine Intrusion. The magmatic rocks from mafic complex are fine to medium-grained and vary in composition from quartz- monzonites to granodiorites and gabbros. Coarse-grained olivine gabbros have intruded these rocks in the west. The granitic body is represented by a peraluminous, biotite-orthoclase-granite and a more evolved leucocratic granite in the outer parts towards the host-rock. Field observations suggest a feeder-zone for the granite in the west and that the granite postdates the mafic complex. Two granite samples of the outermost margins in the Northeast and South were analyzed. The zircons were dated by precise isotope-dilution U-Pb techniques of chemically abraded single grains. The data are concordant within the analytical error and define weighted mean 206/238U ages of 12.59 ± 0.03 Ma and 12.58 ± 0.01 Ma for the two samples respectively. A 40Ar/39Ar-age for the second sample yield a date of 12.37 ± 0.11 Ma. Three 40Ar/39Ar -ages of biotites were obtained for rocks belonging to the mafic complex. A hbl-bio- granodiorite from the central part, approximately 150 m below the subhorizontal contact with the granite, gives an age of 12.81 ± 0.11 Ma. A hbl-bio-granodiorite and an olivine-gabbro west of the feeder-zone date at 12.42 ± 0.14 Ma and 12.49 ± 0.11 Ma, respectively. The obtained older age of 12.81 Ma for the granodiorite in the central part is consistent with structural relationships of brittle fracturing of the mafic

    The Torres del Paine National Park (TPNP) is located on the southern limit of the Andean Southern Ice Field, part of the Magallanes and Antartica Chilena region, in the province of Ultima Esperanza. The TPNP has a very heterogeneous climate due to orographic influence and wet air masses from the Pacific. The geology is basically Cretaceous metasedimentary rocks and Miocene granitic plutons and batholiths. We studied the main soils and geoenvironments of Mt Ferrier mountain and its surroundings, based on soils , landforms and vegetation aspects. The geoenvironmental stratification was based on the combined variation and integration of pedo-litho-geomorphological features with the vegetation. WE used detailed geological maps, a DEM and slope maps and WorlView II satellite images. Fifteen soils profiles were sampled and classified according to Soil Taxonomy (2010) at all genovironments, ranging from 50 m a.s.l to the at high plateau just below the permanent snowline, under periglacial conditions (~1004m asl). Three soil temperature and moisture monitoring sites were set, allowing for 24 consecutive months (2011 to 2013). Seven geoenvironments were identified with distinct soil and landform characteristics, all with a similar geological substrate. The landform and vegetation have a strong connection with the landscape dynamic, controlling erosional and depositional processes, resulting from glacier advances and retreats in the Late Quaternary. Wind blown materials is widespread, in the form of loess material, accumulating in the higher parts of the landscape. On the other hand, accumulation of organic matter in the water-saturated depressions is common in all altitudes. Generally the soils are acidic and dystrophic, with little exceptions. The following geoenvironments were identified: Periglacial Tundra, Loess slopes, Talus and scarpmentd, Fluvio-glacial terraces, Fluvio-lacustrine plains, Moraines and Paleodunes. The regional pedology show the occurrence of five soil

    Among the serious dramas in the Southern hemisphere, the most serious relates to health, and the most serious health problem is dysentery among the rural population, caused by the lack of unpolluted water. Bad management frustrates much of the aid sent to this part of the world, including projects to help the water crisis. In view of the success, it would appear that a concrete solution could be found within a decade, at a cost that can easily be sustained by the rich world, so long as funds are managed honestly. Much more ambitious and, at least for the moment, beyond all concrete possibility, is the project to provide a barrel of water per head to each person in the southern hemisphere. Providing unpolluted water and facilitating farming development through minor irrigation and family cattle-raising schemes is an idea that appears entirely Utopian. The conclusion provides a critical analysis of the major hydraulic works essential for true development, but effective only if the human environment is ready to receive them, whereas minor works are useful in any case - at village level - to resolve the thirst of the southern hemisphere. [Italian] Fra i gravi drammi del Sud del Mondo certamente il piu' grave e' quello sanitario; ed in quello sanitario la dissenteria causata dalla mancanza di acque non inquinate a gran parte della popolazione rurale.

Da alcuni interventi ad esito positivo si puo' pervenire ad una soluzione concreta nel giro di un decennio. Molto piu' ambizioso ed -almeno per ora- fuori da ogni ipotesi concreta e' quello di rifornire di un barile di acqua pro capite ogni individuo del Sud del Mondo: per dare acqua non inquinata e favorire lo sviluppo alimentare attraverso piccole irrigazioni e familiari allevamenti di bestiame: cio' appare, comunque relegato allo scenario

    The shallow magmatic Torres del Paine Intrusive Complex (TPIC) belongs to a series of sub-volcanic and plutonic igneous bodies in Southern Chile and Argentina. This trench-parallel belt is located in a transitional position between the Patagonia Batholith in the West, and the alkaline Cenozoic plateau lavas in the East. While volumetrically small amounts of magmatism started around 28 my ago in the Torres del Paine area, and a second period occurred between 17-16 Ma, it peaked with the TPIC 12.59-12.43 Ma ago. The spectacular cliffs of the Torres del Paine National park provide a unique opportunity to study the evolution of a very shallow magma chamber and the interaction with its host rocks. Intrusion depth can be estimated based on contact metamorphic assemblages and granite solidus thermobarometry to 750±250 bars, corresponding to an intrusion depth of ca. 3km, ca. 500m above the base of the intrusion. Hornblende thermobarometry in mafic rocks agrees well with these estimates (Leuthold et al., 2014). The TPIC is composed of a granitic laccolith emplaced over 90ka (Michel et al., 2008) in 3 major, several 100m thick sheets, forming an overall thickness of nearly 2 km. Contacts are sharp between sheets, with the oldest sheet on the top and the youngest on the bottom (Michel et al., 2008). The granitic laccolith is under-plated by a ca. 400m thick mafic laccolith, built up over ca. 50ka (Leuthold et al. 2012), constructed from the bottom up. Granitic and mafic sheets are themselves composed of multiple metric to decametric pulses, mostly with ductile contacts between them, resulting in outcrop patterns resembling braided stream sediments. The contact of the TPIC with the Cretaceous flysch sediments document intrusion mechanism. Pre-existing sub-horizontal fold axes are rotated in the roof of the TPIC, clearly demonstrating ballooning of the roof; no ballooning was observed in the footwall of the intrusion. Extension during ballooning of the roof is indicated by

    The purpose of this study was to evaluate the association between job characteristics and musculoskeletal pain among shift workers employed at a 24-hour poultry processing plant in Southern Brazil. This was a cross-sectional study of 1,103 production line workers aged 18-52 years. The job characteristics of interest were shift (day/night), shift duration, and plant sector ambient temperature. Musculoskeletal pain was defined as self-reported occupational-related pain in the upper or lower extremities and trunk, occurring often or always, during the last 12 months. The mean (SD) participant age was 30.8 (8.5) years, and 65.7% of participants were women. The prevalence of musculoskeletal pain was greater among female participants than male participants. After adjustment for job characteristics and potential confounders, the prevalence ratios (PR) of lower extremity musculoskeletal pain among female workers employed in extreme-temperature conditions those working the night shift, and those who had been working longer on the same shift were 1.75 (95% CI 1.12, 2.71), 1.69 (95% CI 1.05, 2.70), and 1.64 (95% CI 1.03, 2.62), respectively. In male workers, only extreme-temperature conditions showed a significant association with lower extremity musculoskeletal pain (PR=2.17; 95% CI 1.12, 4.22) after adjustment analysis. These findings suggest a need for implementation of measures to mitigate the damage caused by nighttime work and by working under extreme temperature conditions, especially among female shift workers, such as changing positions frequently during work and implementation of rest breaks and a workplace exercise program, so as to improve worker quality of life.

    The 12 Ma old Torres del Paine laccolith (TPL) is part of a chain of isolated Miocene plutons and subvolcanic rocks which intruded the foothills of the southern Andes of Chile and Argentina (Halpern, 1973; Michael, 1984). The 12x12 km big laccolith, an I-type granite, intruded mudstones, sandstones, carbonates and conglomerates of the Cretaceous Cerro Torre and Punta Barrosa formation (Wilson, 1991) creating a well defined, but small contact aureole of 200-400m width. The TPL contains abundant textural evidence of fluid exsolution and eutectic crystallisation. It hence represents a good example for the transport of large quantities of magmatic aqueous fluids to the uppermost level of the crust. The pluton is well exposed and its rugged topography allows the investigation of the roof, the lateral rims and the base of the intrusion. Field and textural observations, phase petrological constraints, oxygen isotope and fluid inclusion data are used to unravel mechanism and patterns of fluid and heat transport in the intrusion and the contact aureole. The Torres del Paine Intrusives form a calcalkaline suite, ranging from gabbros through diorites to leucogranites. The intrusive body has the general shape of a laccolith (Skarmeta and Castelli, 1997). Gabbroic and dioritic rocks are only exposed at the lower levels. Granites are clearly predominant - the main body of the laccolith is composed of a fine to medium grained biotite-orthoclase granite. The TPL is remarkable for its abundance of miarolitic cavities. Locally, at the margins of the pluton, a microgranitic phase is found with up to 15% of cavities. While some miaroles are isolated, others are interconnected, forming tube-like structures. Open miaroles contain euhedral crystals of quartz and feldspar. Other important phases are biotite, tourmaline, fayalite and late chlorite and carbonate. Individual crystals are typically between < 1cm up to a few cm in length. Some miaroles are completely filled with coarse quartz

    adjacent to the treated vertebrae. Discussion and conclusions: Since the first case of vertebroplasty was used in vertebral haemangioma, the possibility of using this technique in other pathological conditions such a metastatic lesions and osteoporotic compression fractures has been clear. MR has a key role in the selection of patients while bone scan and CT can be useful in selected cases. Absolute contraindication is local or systemic infection while relative contraindications are epidural extension of the neoplastic lesion, vertebra plana, clinical signs of myelopathy of radiculopathy and coagulation disorders. The results of our study were better in patients treated for osteoporosis or haemangioma than in cancer patients. We consider percutaneous vertebroplasty a valid technique for the treatment of the pain due to osteoporotic compression fractures, vertebral haemangiomas or metastatic lesions.

    South Patagonian peatlands cover a wide range of the southern terrestrial area and thus are an important component of the terrestrial global carbon cycle. These extremely southern ecosystems have been accumulating organic material since the last glaciation up to now and are - in contrast to northern hemisphere bogs - virtually unaffected by human activities. So far, little attention has been given to these pristine ecosystems and great carbon reservoirs which will potentially be affected by climate change. We aim to fill the knowledge gap in the quantity of carbon released from these bogs and in what controls their fluxes. We study the temporal and spatial variability of carbon fluxes in two contrasting bog ecosystems in southern Patagonia, Tierra del Fuego. Sphagnum-dominated bog ecosystems in Tierra del Fuego are similar to the ones on the northern hemisphere, while cushion plant-dominated bogs can almost exclusively be found in southern Patagonia. These unique cushion plant-dominated bogs are found close to the coast and their occurrence changes gradually to Sphagnum-dominated bogs with increasing distance from the coast. We conduct closed chamber measurements and record relevant environmental variables for CO2 and CH4 fluxes during two austral vegetation periods from December to April. Chamber measurements are performed on microforms representing the main vegetation units of the studied bogs. Gas concentrations are measured with a fast analyzer (Los Gatos Ultraportable Greenhouse Gas Analyzer) allowing to accurately record CH4 fluxes in the ppm range. We present preliminary results of the carbon flux variability from south Patagonian peat bogs and give insights into their environmental controls. Carbon fluxes of these two bog types appear to be highly different. In contrast to Sphagnum-dominated bogs, cushion plant-dominated bogs release almost no CH4 while their CO2 flux in both, photosynthesis and respiration, can be twice as high as for Sphagnum

    Conflicting reports exist regarding the prevalence of Modic changes among low back pain (LBP) patients and factors associated with their existence. To assess the prevalence of Modic changes and other findings on lumbar magnetic resonance imaging (MRI) among Spanish adult chronic LBP patients and the patient characteristics and radiological findings associated with Modic changes. A cross-sectional imaging study among chronic LBP patients. Four hundred eighty-seven patients (263 women and 224 men) undergoing lumbar spine MRI examination for chronic LBP. Gender, age, body mass index (BMI), lifetime smoking exposure, degree of physical activity, and image features (disc degeneration, type and extension of Modic changes, disc contour, annular tears, spinal stenosis, and spondylolisthesis). Ten radiologists from six hospitals across six cities in Spain consecutively recruited adult patients in whom lumbar MRI had been prescribed for LBP lasting ≥3 months. Patients' characteristics and imaging findings were assessed through previously validated instruments. A multivariate logistic regression model was developed to assess the features associated with Modic changes. Modic changes were found in 81% of the patients. The most common was Type II (51.3%), affecting only the end plate. Variables associated with Type I changes were disc contour abnormalities, spondylolisthesis, and disc degeneration. The same variables were associated with a higher risk of Type II or any type of Modic changes, as well as being male, and having a higher BMI. Modic changes are found in 81% (95% confidence interval, 77-85) of adult Spanish patients in whom an MRI is prescribed for chronic LBP. Modic changes are more likely to be found in males with a high BMI, who also show disc contour abnormalities, spondylolisthesis, or disc degeneration. Copyright © 2011 Elsevier Inc.

    Ecotourism and protected area visitation in Central and South America are largely dependent upon a relatively undisturbed quality of natural resources. However, visitation may impact vegetation, soil, water and wildlife resources, and degrade visitor facilities such as recreation sites and trails. Findings are reported from trail impact research conducted at Torres del Paine National Park in Patagonia, Chile. The frequency and magnitude of selected trail impacts and the relative effect of the amount of use, vegetation type, trail position and trail grade are investigated. Findings differed from previous studies in that amount of use was significantly related to both trail width increases and trail erosion. Management actions to minimize trail impacts are offered.

    This study focuses on the identification of multiple latent trajectories of pain intensity, and it examines how religiousness is related to different classes of pain trajectory. Participants were 720 community-dwelling older adults who were interviewed at four time points over a 3-year period. Overall, intensity of pain decreased over 3 years. Analysis using latent growth mixture modeling (GMM) identified three classes of pain: (1) increasing ( n = 47); (2) consistently unchanging ( n = 292); and (3) decreasing ( n = 381). Higher levels of intrinsic religiousness (IR) at baseline were associated with higher levels of pain at baseline, although it attenuated the slope of pain trajectories in the increasing pain group. Higher service attendance at baseline was associated with a higher probability of being in the decreasing pain group. The increasing pain group and the consistently unchanging group reported more negative physical and mental health outcomes than the decreasing pain group.

    Situated at the southern margin of the hemispheric westerly wind belt and immediately north of the Antarctic Polar Frontal zone, Tierra del Fuego is well-positioned to monitor coupled changes in the ocean-atmosphere system of the high southern latitudes. Here we describe a Holocene paleoclimate record from sediment cores obtained from Lago Fagnano, a large lake in southern Tierra del Fuego at 55{sup o}S, to investigate past changes in climate related to these two important features of the global climate system. We use an AMS radiocarbon chronology for the last 8,000 years based on pollen concentrates, thereby avoiding contamination from bedrock-derived lignite. Our chronology is consistent with a tephrochronologic age date for deposits from the middle Holocene Volcan Hudson eruption. Combining bulk organic isotopic ({delta}{sup 13}C and {delta}{sup 15}N) and elemental (C and N) parameters with physical sediment properties allow us to better understand sediment provenance and transport mechanisms and to interpret Holocene climate and tectonic change during the last 8,000 years. Co-variability and long-term trends in C/N ratio, carbon accumulation rate, and magnetic susceptibility reflect an overall Holocene increase in the delivery of terrestrial organic and lithogenic material to the deep eastern basin. We attribute this variability to westerly wind-derived precipitation. Increased wind strength and precipitation in the late Holocene drives the Nothofagus forest eastward and enhances run-off and terrigenous inputs to the lake. Superimposed on the long-term trend are a series of abrupt 9 negative departures in C/N ratio, which constrain the presence of seismically-driven mass flow events in the record. We identify an increase in bulk {delta}{sup 13}C between 7,000 and 5,000 cal yr BP that we attribute to enhanced aquatic productivity driven by warmer summer temperatures. The Lago Fagnano {delta}{sup 13}C record shows similarities with Holocene records of sea surface

    Sub-Saharan Africa faces an increasing incidence and prevalence of life-limiting and life-threatening conditions. These conditions are associated with a significant burden of pain linked to high morbidity and disability that is poorly assessed and undertreated. Barriers to effective pain management partly relate to lack of access to opioid analgesia and challenges in their administration. To identify country-specific and broader regional barriers to access, as well as the administration of opioids, and generate recommendations for advancing pain management in Southern Africa. A parallel mixed methods design was used across three countries: Mozambique, Swaziland, and Zimbabwe. Three activities were undertaken: 1) a review of regulatory and policy documentation, 2) group interviews, and 3) a self-administered key informant survey. Barriers to accessing opioid analgesics for medical use include overly restrictive controlled medicines' laws; use of stigmatizing language in key documents; inaccurate actual opioid consumption estimation practices; knowledge gaps in the distribution, storage, and prescription of opioids; critical shortage of prescribers; and high out-of-pocket financial expenditures for patients against a backdrop of high levels of poverty. Policies and relevant laws should be updated to ensure that the legislative environment supports opioid access for pain management. Action plans for improving pain treatment for patients suffering from HIV or non-communicable diseases should address barriers at the different levels of the supply chain that involve policymakers, administrators, and service providers.

    Full Text Available A number of glacial moraines are distributed from the eastern margin of the Torres del Paine drainage basin to near the present margin of the Patagonian Ice Fields, together with a set of regionally continuous lacustrine terraces related to glacial fluctuations. The geomorphology, supported by lake sediment evidence, indicates the existence of a single proglacial paleolake in this area, here referred to as the Great Tehuelche Paleolake. This concept helps to clarify the chronology of glacial events and leads to a better understanding of the evolution of the hydrologic system in the Torres del Paine area. Glacial advances previously referred to as A, B and C occurred during the Last Glacial Maximum and fed the Great Tehuelche Paleolake with meltwater, allowing it to reach its maximum extension. The discovery of thrombolites at Laguna Amarga suggests that the drainage of the paleolake towards the Última Esperanza Fjord took place at 7,113 Cal. yr BP, after the melting of an ice barrier that existed during the earlier glacial advance. This gave rise to the development of a complex fluvio-lacustrine hydrologic system that persists to the present day.Un grupo de morrenas glaciales están distribuidas desde el margen este de la cuenca de drenaje de Torres del Paine hacia el margen actual de los Campos de Hielo Patagónicos. Las morrenas se observan en conjunto con un grupo de terrazas lacustres regionales, las cuales están vinculadas a las fluctuaciones glaciales. La geomorfología y evidencias de sedimentos lacustres indican la existencia de un único lago proglacial, referido en este estudio como Gran Paleolago Tehuelche. Este concepto ayuda a clarificar la cronología de los eventos glaciales y permite una mejor comprensión de la evolución del sistema hidrológico del sector de Torres del Paine.

    The evolution of Southeast Gulf of Mexico comprises three main periods: pre-orogenic, syn-orogenic and post-orogenic. During pre-orogenic time, from Lower Jurassic to Campanian, the stages are the rift of Pangaea and the thermal subsidence (or drift). In drift stage two domains interacted in the space; the carbonate platforms (Bahamas, Yucatan, Organos and others), and the deepwater basins. These fluctuations were dictated by the differential subsidence and horizontal displacements of basement blocks as well as by the eustatic movements of the ocean. The Organos platform, for example, was entirely drowned since Upper Jurassic and the sedimentation continued in deepwater environment. The collision between Great Antilles Volcanic Arc and the continental margins since Upper Cretaceous modeled the Cuban orogen. Here, the southern facies thrusted over the northern section with simultaneous strike-slip movements. The interaction suddenly ceased in Eocene. The source rock levels are considerably more frequent in the deepwater domain than in the platforms. The Lower and Upper Jurassic as well as Lower and Middle Cretaceous horizons contain very high levels of organic matter. The offshore seismic shows the transition from the thrusted belt to the foreland basin with a typical triangle zone configuration. Reservoirs are expected in the Cretaceous section covered by seals conformed by early foreland basin sediments of Upper Cretaceous-Paleocene age. Foothill structures has a great potential for hydrocarbon exploration.

The findings of our study indicate that patient compliance with back pain treatment is a serious and complex problem. Nevertheless, while this study was only an exploratory one, we believe that the results of this study can be used by care providers to identify patients likely to become noncompliant and also by researchers to plan specific studies on the effectiveness of treatment programs for patients with low back pain.Objetivos. Aunque se han hecho grandes esfuerzos por encontrar tratamientos eficaces para las lumbalgias, la eficacia de las diferentes modalidades terapéuticas puede depender de su cumplimiento por parte del paciente.

    Explosive eruptions of large-volume rhyolitic magma systems are common in the geologic record and pose a major potential threat to society. Unlike other natural hazards, such as earthquakes and tsunamis, a large rhyolitic volcano may provide warning signs long before a caldera-forming eruption occurs. Yet, these signs—and what they imply about magma-crust dynamics—are not well known. This is because we have learned how these systems form, grow, and erupt mainly from the study of ash flow tuffs deposited tens to hundreds of thousands of years ago or more, or from the geophysical imaging of the unerupted portions of the reservoirs beneath the associated calderas. The Laguna del Maule Volcanic Field, Chile, includes an unusually large and recent concentration of silicic eruptions. Since 2007, the crust there has been inflating at an astonishing rate of at least 25 cm/yr. This unique opportunity to investigate the dynamics of a large rhyolitic system while magma migration, reservoir growth, and crustal deformation are actively under way is stimulating a new international collaboration. Findings thus far lead to the hypothesis that the silicic vents have tapped an extensive layer of crystal-poor, rhyolitic melt that began to form atop a magmatic mush zone that was established by ca. 20 ka with a renewed phase of rhyolite eruptions during the Holocene. Modeling of surface deformation, magnetotelluric data, and gravity changes suggest that magma is currently intruding at a depth of ~5 km. The next phase of this investigation seeks to enlarge the sets of geophysical and geochemical data and to use these observations in numerical models of system dynamics.

  16. Crustal seismicity associated to rpid surface uplift at Laguna del Maule Volcanic Complex, Southern Volcanic Zone of the Andes

    Laguna del Maule Volcanic Complex (LMVC, Southern Andes of Chile) has been experiencing large rates (ca. 30 cm/yr) of surface uplift as detected since 2008 by satellite geodetic measurements. Previous works have modeled the source of this deformation as an inflating rectangular sub-horizontal sill underlying LMVC at 5 km depth, which is supposedly related to an active process of magmatic replenishment of a shallow silicic reservoir. However little is known about the tectonic context on which this activity is taking place, particularly its relation with crustal seismicity that could help understanding and monitoring the current deformation process. Here we present the first detailed characterization of the seismic activity taking place at LMVC and integrate it with structural data acquired in the field in order to illuminate the possible connection between the ongoing process of surface uplift and the activation of crustal faults. Our main finding is the recognition of repetitive volcano-tectonic (VT) seismic swarms that occur periodically between 2011 and 2014 near the SW corner of the sill modeled by InSAR studies. A cross-correlation analysis of the waveforms recorded for these VT events allows identifying three different seismic families. Families F1 and F3 share some common features in the stacked waveform and its locations, which markedly differ from those of family F2. Swarms belonging to this later family are more energetic and its energy was increasing since 2011 to a peak in January 2013, which coincide with maximum vertical velocities detected by local GPS stations. This points to a common process relating both phenomena. The location of VT seismic swarms roughly coincides with the intersection of a NE-SW lineament with a WNW-ESE lineament. The former shows clear field evidences of dextral strike-slip that are fully consistent with one nodal plane of focal mechanism for well-recorded F2 events. The conjugate nodal plane of these focal mechanisms could

    Full Text Available Background: Low back pain (LBP is the most common symptom which is associated with limitation of normal activities and work-related disability. Imaging techniques are often essential in making the correct diagnosis for prompt management. Plain Radiography though remain a first imaging modality, magnetic resonance imaging (MRI due to its inherent softtissue contrast resolution and lack of ionizing radiation remains invaluable modality in the evaluation of LBP. Aim: To find the common causes of LBP in different age groups and the role of MRI in detecting the spectrum of various pathological findings. Materials and Methods: This is a prospective study done in the Department of Radiodiagnosis during a period of 2 years from July 2013 to July 2015. The study population includes all the cases referred to our department with complaints of LBP. Patients with ferromagnetic metallic implants and uncooperative cases were excluded. HITACHI 0.4 Tesla open MRI machine was used for imaging. Results and Conclusion: This study involved a total of 235 cases. There were 121 males and 114 females. The age of the patient ranged from 21 to 68 years with an average of 41.3 years. Back pain was commonly observed in the third to fifth decade. The common causes for back pain are disc herniations (disc bulge - 35.3%, disc protrusion - 39.6%, disc extrusion - 7.2% accounting to 82.1%, followed by normal study (10.2%, vertebral collapse (traumatic - 2.1%, osteoporotic - 1.7%, infections (2.1%, and neoplasm (1.7%. MRI provides valuable information regarding the underlying causes of LBP, especially in disc and marrow pathology.

    The Laguna del Maule (LdM) volcanic field of the Andean Southern Volcanic Zone extends over 500 square kilometers and comprises more than 130 individual vents. As described by Hildreth et al. (2010), the history has been defined from sixty-eight Ar/Ar and K-Ar dates. Silicic eruptions have occurred throughout the past 3.7 Ma, including welded ignimbrite associated with caldera formation at 950 ka, small rhyolitic eruptions between 336 and 38 ka, and a culminating ring of 36 post-glacial rhyodacite and rhyolite coulees and domes that encircle the lake. Dating of five post-glacial flows implies that these silicic eruptions occurred within the last 25 kyr. Field relations indicate that initial eruptions comprised modest volumes of mafic rhyodacite magma that were followed by larger volumes of high silica rhyolite. The post-glacial flare-up of silicic magmatism from vents distributed around the lake, is unprecedented in the history of this volcanic field. Using satellite radar interferometry (InSAR), Fournier et al. (2010) measured uplift at a rate of more than 180 mm/year between 2007 and 2008 in a round pattern centered on the west side of LdM. More recent InSAR observations suggest that rapid uplift has continued from 2008 through early 2011. In contrast, Fournier et al. found no measurable deformation in an interferogram spanning 2003 through 2004. In this study, we model the deformation field using the General Inversion of Phase Technique (GIPhT), as described by Feigl and Thurber (2009). Two different models fit the data. The first model assumes a sill at ~5 km depth has been inflating at a rate of more than 20 million cubic meters per year since 2007. The second model assumes that the water level in the lake dropped at a rate of 20 m/yr from January 2007 through February 2010, thus reducing the load on an elastic simulation of the crust. The rate of intrusion inferred from InSAR is an order of magnitude higher than the average rate derived from well-dated arc

El objetivo de la evaluación del dolor debe ser el de proporcionar datos precisos para determinar cuáles acciones deben ser toma de las para aliviarlo o eliminarlo y la mismo tiempo, evaluar la eficacia de esas acciones. La finalidad de esta revisión fue discutir los métodos utilizados en la evaluación del dolor en neonatología, cuando las estrategias de tratamiento utiliza de las sin una evaluación sistemática del dolor no son eficaces o adecua de las. CONTENIDO: No existe ninguna técnica ampliamente aceptada y fácilmente ejecutable y uniforme para la evaluación del dolor en niños, especialmente en los recién nacidos y lactantes que pueda ser utilizada en todas las situaciones. Antes de confiar en la exactitud de los datos de Evaluación, se hace necesario que los profesionales de la salud se sientan seguros con los instrumentos usados en la recolección del esos datos. Varios indicadores pueden ser usados en la evaluación, cuantificación y calificación del estímulo doloroso, y cuando se analizan en conjunto, permiten el desglose entre el dolor y los estímulos no dolorosos. Aunque sea deseable la estandarización objetiva para la medición de la intensidad del dolor, tal medida no existe todavía. La medición ene sea franja etaria es hecha por medio de parámetros fisiológicos (frecuencia cardíaca, frecuencia respiratoria, presión arterial, etc y comportamentales (expresión facial, postura y vocalización o verbalización, utilizando escalas de evaluación, cada una con sus ventajas y limitaciones. CONCLUSIONES: La actual atención para mejores métodos de medida y evaluación del dolor aportó para aumentar la sensibilidad de los profesionales de salud con relación a la naturaleza de las experiencias dolorosas.

    Full Text Available A series of Quaternary lacustrine braid deltas on the shores of Lake General Carrera in southern Chile formed as a result of falls in lake level. Each delta comprises two components, the delta fan and the beach embayment, each in turn comprising an onshore subaerial and an offshore subaqueous element. The delta fans have a classic Gilbert form with a braided delta top and a steeply inclined delta front. Adjacent to the fans are concave beach embayments that formed parallel with the deltas as they prograded into the lake. The delta sediments consist predominantly of matrix- and clast-supported gravéis to a total composite thickness exceeding 400 m. The depositional environments are dominated by ephemeral river flooding and by storm-driven waves. Beach sediment is sorted, rounded, winnowed and transported alongshore by waves to fill the beach embayment with ridges of very well sorted and well-rounded gravel. A gently-dipping shoreface platform occurs up to 100 m offshore between the beach and the brink point. From the brink point, in water depth of about 8 m, sediment cascades down the steep delta front slope to form long foresets extending to the lake floor. The sedimentary successions therefore wedge in the opposite direction from those of tectonically controlled basin margins where fan growth keeps pace with basin subsidence.Una serie de deltas entrelazados lacustres, pertenecientes al Cuaternario, ubicados en las costas del lago General Carrera, en el sur de Chile, se formaron como resultado de caídas en el nivel del lago. Cada delta consta de dos componentes: el abanico deltaico y la zona de embahiamiento. Cada uno de ellos tiene, a su vez, un elemento subaéreo costero y un elemento subacuático. Los abanicos deltaicos tienen una forma Gilbert clásica con una parte superior de ríos entrelazados y un frente deltaico empinado. Adyacente a los abanicos aluviales existen bahías cóncavas de playa que se formaron de manera paralela a los

  7. Petrological evolution of subducted rodingite from seafloor metamorphism to dehydration of enclosing antigorite-serpentinite (Cerro del Almirez massif, southern Spain)

    Rodingites are common rocks associated with serpentinites in exhumed terrains that experienced subduction and high pressure metamorphism. However, the response of these rocks to devolatilization and redox reactions in subduction settings is not well constrained. In the Cerro del Almirez ultramafic massif (southern Spain) rodingites constitute about 1-2% of the total volume of exposed rocks. Metarodingites are enclosed in antigorite-serpentinite and chlorite-harzburgite separated by a transitional zone that represents the front of prograde serpentinite-dehydration in a paleo-subduction setting (Padrón-Navarta et al., 2011). Metarodingites occur as boudin lenses, 1 to 20 m in length and 30 cm to 2 m in thickness. During serpentinization of peridotite host rocks, dolerites and basalts precursor of rodingites underwent intense seafloor metasomatism, causing the enrichment in Ca and remobilization of Na and K. Subsequent metamorphism during subduction transformed the original igneous and seafloor metamorphic mineralogy into an assemblage of garnet (Ti-rich hydrogrossular), diopside, chlorite, and epidote. During prograde metamorphism, garnet composition changed towards higher andradite contents. High-pressure transformation of enclosing antigorite-serpentinite to chlorite-harzburgite released fluids which induced breakdown of garnet to epidote in metarodingites. Ti liberation by this latter reaction produced abundant titanite. Released fluids also triggered the formation of amphibole by alkalis addition. Highly recrystallized metarodingites in chlorite-harzburgite present a new generation of idiomorphic garnet with composition equal to 10-30% pyrope, 30-40% grossular and 35-55% almandine + spessartine. This garnet has titanite inclusions in the core and rutile inclusions in the rim. The contact between metarodingites and ultramafic rocks consists of a metasomatic zone (blackwall) with variable thickness (7 to 40 cm) constituted by chlorite, diopside, and titanite

    Grotta del Romito has been the subject of numerous archaeological, chronological and palaeoenvironmental investigations for more than a decade. During the Upper Palaeolithic period the site contains evidence of human occupation through the Gravettian and Epigravettian periods, multiple human burials, changes in the pattern of human occupation, and faunal, isotopic and sedimentological evidence for local environmental change. In spite of this rich record, the chronological control is insufficient to resolve shifts in subsistence and mobility patterns at sufficiently high resolution to match the abrupt climate fluctuations at this time. To resolve this we present new radiocarbon and tephrostratigraphic dates in combination with existing radiocarbon dates, and develop a Bayesian age model framework for the site. This improved chronology reveals that local environmental conditions reflect abrupt and long-term changes in climate, and that these also directly influence changing patterns of human occupation of the site. In particular, we show that the environmental record for the site, based on small mammal habitat preferences, is chronologically in phase with the main changes in climate and environment seen in key regional archives from Italy and Greenland. We also calculate the timing of the transitions between different cultural phases and their spans. We also show that the intensification in occupation of the site is chronologically coincident with a rapid rise in Mesic Woody taxa seen in key regional pollen records and is associated with the Late Epigravettian occupation of the site. This change in the record of Grotta del Romito is also closely associated stratigraphically with a new tephra (the ROM-D30 tephra), which may act as a critical marker in environmental records of the region.

    Valeri, G.; Ferrara, C. (Ancona Univ. (Italy). Cattedra di Radiologia); Carloni, S. (Ancona Univ. (Italy). Cattedra di Ortopedia) (and others)

    The purpose of this paper is to investigate the clinical role of Magnetic Resonance Arthrography (MRA) of the wrist in subjects with chronic pain. Thirty-five patients complaining of wrist pain for more than 6 months were submitted to MRI an MRA. All patients received and intra-articular injection of 2-10 mL of a 10 mmol saline solution of Gd-DPTA. The overall diagnostic accuracy rates of MRI and MRA were 40% and 81% respectively, with sensitivity and specificity of 63% and 39% (MRI) and of 82% and 79% (MRA). The conclusion is that compared with MRI, MRA can be considered a useful tool for the visualization of interosseus carpal ligaments and of the triangular fibrocartilage complex. MRA also helps detect injuries in these structures.

    Full Text Available Stomach contents of 282 false southern king crabs (Paralomis granulosa, between 10 to 90 mm CL from the Beagle Channel (Golondrina Bay and Roca Mora, Argentina, were examined by the frequency of occurrence method of analysis and by a food index. Roca Mora is an area where juveniles ( 60 mm CL are common; in this last area sexual segregation was also observed. The principal food groups for crabs of Golondrina Bay were algae, molluscs, crustaceans, bryozoans and foraminiferans; for crabs from Roca Mora the natural diet consisted of three major food groups: hydrozoans, echinoderms and foraminiferans. The relative frequency of different prey groups varied in relation to the size, season and sex. There were no significant differences in the quantity of food consumed by sexes in both areas. Generally small crabs ( 50 mm CL. Juveniles consumed a greater amount of food during winter and spring. In summer (moulting period, juveniles had the highest vacuity index. Adults consumed minor amounts of food during autumn, before the spawning-moulting-mating period when the vacuity index was higher (spring.

    The Pain Clinic of the CIMEQ offers treatment to patients with different pathologies, using interventional techniques as the radiology like visual guide to reach the target structure and to apply the election technique. The personnel that carry out these procedures are inserted in the program of radiological surveillance of the institution, reason for which a radiological event could be detected where the main physician responsible of the service was implied. In this work the results of an investigation are presented realized with the objective of to know the causes of the event and to determine the necessary measures to avoid that this repeats again. The investigation was oriented to three fundamental aspects: medical exam of the affected worker; evaluation of the operational procedures from the radiological protection view point; and dosimetric measurements simulating the real conditions of work for which were used ionization chamber, radiometer and PMMA mannequin. As a result of the medical exam was detected that the main physician of the service did not use during the execution of all the procedures the extremities dosimetry and that he presented a radio induced erythema in the right hand, reason for which he was separated of the activity with ionizing radiations, until the conclusion of the investigation. With relationship to the evaluation of the operational procedures from the radiological protection view point, was verified that the medical physician not carried out any collimation of the beam and he was located in the positions where the dose rate reached the maximum values, frequently introducing the hands in the direct beam; that which implied an overexposure of the superior extremities and a not optimized exposure for whole body. This result was proven with the realized experimental measurements, which gave dose estimated values in extremities of the order of the deterministic effects. The investigation facilitated to introduce modifications in the

    Full Text Available The diversity and distribution of appendicularians on the continental shelf and upper part of the oceanic sea in the southern Gulf of Mexico is analyzed here for the first time. Samples were collected in September 2003 using a fine mesh net. Twenty species were identified, of which Fritillaria venusta and Pelagopleura oppressa are first records for the Gulf of Mexico. Oikopleura species occur throughout the area, with greatest abundances in the upwelling waters of the inner shelf off Yucatán and Campeche. The greatest abundances of Fritillaria species and of the other genera were recorded in the mid, outer shelf, and oceanic areas of Campeche and Tabasco that are influenced by continental water discharges and an oceanic gyre. Diversity and abundance varied in differing directions, with high abundance and low diversity characterizing the costal areas and low abundance and high diversity in the mid, outer shelf, and oceanic areas. The distribution of appendicularian species appears to be influenced by upwelling currents, gyres, water column depth, continental water discharges, salinity, and temperature. However, it could be assumed that the reasons behind these physical environmental factors include the food supply, a short life cycle, and high reproductive efficiency, factors that are commonly associated with distribution.Se analiza por primera vez la diversidad y distribución de las apendicularias en la capa superficial de la columna de agua de la plataforma continental del sur del Golfo de México.

    indicaciones, todavía están en fase de comprobación con relación a su eficacia. El objetivo de este estudio fue revisar el historial, las propiedades farmacológicas y las aplicaciones clinicas de la TxB, cuando se usa en el tratamiento de dolores de diferentes etiologías. CONTENIDO: La TxB es el producto de la fermentación del Clostridium Botulinum, una bacteria anaerobia Gram-positiva. Comercialmente, las TxB existen bajo las formas A y B, agentes biológicos obtenidos laboratorialmente. La TxB, una neurotoxina que posee una alta afinidad por las sinapsis colinérgicas, ocasiona un bloqueo en la liberación de acetilcolina por el terminal nervioso, sin alterar la conducción neural de las señales eléctricas o la síntesis y el almacenaje de acetilcolina. Se ha comprobado que la TxB puede debilitar selectivamente la musculatura dolorosa, interrumpiendo el ciclo espasmo-dolor. Con relación a él, varias publicaciones han demostrado la eficacia y la seguridad de la TxB-A en el tratamiento de la cefalea tipo tensión, migraña, dolor lumbar crónico y dolor miofacial. CONCLUSIONES: La TxB-A es segura y se tolera muy bien en los desórdenes dolorosos crónicos, donde los regímenes de farmacoterapia pueden de hecho provocar efectos colaterales. Otra ventaja es la reducción del uso de analgésicos y el tiempo de acción de 3 a 4 meses por dosis. Sin embargo, investigaciones futuras serán necesarias para establecer la eficacia de la TxB-A en los desórdenes dolorosos crónicos y su exacto mecanismo en el alivio del dolor, como también su potencial en tratamientos multifactoriales.BACKGROOUND AND OBJECTIVES: Botulinum toxin (BTX is one of the most potent bacterial toxins known and its effectiveness in the treatment of some pain syndromes is well known.

    Cumulate and crystal mush disruption and reactivation are difficult to recognise in coarse grained shallow plutonic rocks. Mafic minerals included in hornblende and zoned plagioclase provide snapshots of early crystallization and cumulate formation, but are difficult to interpret in terms of the dynamics of magma ascent and possible links between silicic and mafic rock emplacement. We will present the field relations, the microtextures and the mineral chemistry of the Miocene mafic sill complex of the Torres del Paine intrusive complex (Patagonia, Chile) and its sub-vertical feeder-zone. The mafic sill complex was built up by a succession of braided sills of shoshonitic and high-K calc-alkaline porphyritic hornblende-gabbro and fine grained monzodioritic sills. The mafic units were over-accreted over 41±11 ka, underplating the overlying granite. Local diapiric structures and felsic magma accumulation between sills indicate limited separation of intercumulus liquid from the mafic sills. Anhedral hornblende cores, with olivine + clinopyroxene ± plagioclase ± apatite inclusions, crystallized at temperatures >900°C and pressures of ~300 to ~500 MPa. The corresponding rims and monzodiorite matrix crystallized at 950°C) from the middle crust reservoir to the emplacement level. We show that hornblende-plagioclase thermobarometry is a useful monitor for the determination of segregation conditions of granitic magmas from gabbroic crystal mushes, and for monitoring the evolution of shallow crustal magmatic crystallization, decompression and cooling.

In the assumption that crystalline silicon (single and multi-crystalline) will remain the base material for the commercially available PV generators, technological progress and gain in manufacturing experience as well as economies of scale will bring the production cost of the PV modules to 2 $/W{sub p} by the end of the decade (1996-2005), from the current 4-5 $/W{sub p}. At the current module-shipment growth rate, no silicon feed-stock problem should arise. In the following decade (2006-2015) a technological breakthrough will take place (thin-film based modules will become commercially available) so that the production cost of the modules will be 1 $/W{sub p} or less. The photovoltaic potential for rural electrification it is evaluated considering: the households not connected to the electricity grid, in low population-density areas and with daily global solar irradiation (mean annual) higher than (4.2 kWh) (m{sup -2}) (day{sup -1}); an average household consumption for two cases, the first to satisfy the very basic needs (basic needs case, corresponding to an electricity consumption of (550 Wh) (day{sup -1})) and the other to take into account an evolution of the demand (more comfort case, that is a consumption of (1400 Wh) (day{sup -1})).

    The Miocene Torres del Paine intrusive complex (TPIC) in Patagonia is a transitional alkaline backarc intrusion1 emplaced on short timescales of 162 ± 11 ka2. It is subdivided into two units with distinct ages of ~12.6 Ma and ~12.45 Ma1. Smaller intrusive bodies in the area record a change in chemistry from calc-alkaline at ~16 Ma, to transitional alkaline at ~12.5 Ma. Zircons from ~16 Ma intrusives and the 12.6 Ma part of the TPIC have remarkably consistent, slightly enriched Hf isotope compositions with ɛHf(i) of -1 to +2. An abrupt shift towards more juvenile Hf isotope compositions is observed in the ~12.45 Ma part of the TPIC, with ɛHf(i) of +3 to +6. Bulk rock Nd and Sr isotopes for the TPIC show the same shift towards more juvenile compositions at this time1. The long-term consistency of ɛHf(i) from 16 to 12.6 Ma is surprising, given that in the same period the bulk rock chemistry changes from calc-alkaline to transitional alkaline. Conversely, the major shift in ɛHf(i) is not correlated with any change in bulk rock chemistry, which remains transitional alkaline from 12.6 to 12.45 Ma. The decoupling of major element chemical evolution and Hf isotope signatures suggests that the subsequent rapid influx of juvenile material recorded by our Hf isotope data must have occurred by renewed mantle melting. Subduction of the Chile ridge at ~12.5 Ma in this area caused arc magmatism to move westwards and back-arc extension to initiate. We propose that the first TPIC magmas (12.6 Ma) came from a mantle wedge with a residual subduction signature. Subsequent melting of more juvenile mantle, less contaminated by a subduction component, generated the 12.45 Ma TPIC magmas. These results demonstrate that magmatic complexes such as the TPIC may tap distinct mantle sources even on very short timescales, fingerprinting arc-backarc transition processes. 1Leuthold et al., 2013, JPET, 54: 273-303 2Leuthold et al., 2012, EPSL, 325: 85-92

Material and method: this is a prospective and descriptive study in which 40 patients, 18 men and 22 women with an average of 47 years, were included. They had chronic anal pain of at least 3 months' duration. A complete colonoscopy was performed in all patients, which found no abnormalities to explain clinical symptoms. Patients with anal fissure and internal hemorrhoids of any degree, perianal suppurative processes, and pelvic surgery were excluded from the study. An ALOKA ProSound SSD-4000 ultrasound console attached to a multifrequency radial transductor ASU-67 (7.5 and 10 MHz was used. Results: one patient could not tolerate the examination.

    Purpose: To show the morphological changes in postoperative lumbar spine. Material and methods: We reviewed 128 Magnetic Resonance Imaging (MRI) studies of lumbar spine. All patients complained of low back pain and had a previous lumbar surgery (1 month to 8 years). All the examinations include axial and sagittal Gadopentate-dimeglumine enhanced T1 weighted imaging. Results: Only 7,8% have the normal appearance of the postoperative lumbar spine. Epidural scar was found in 69% of examinations; of this group, 72% showed radicular involvement, and 28% had no radicular involvement. Recurrent disc herniation was found in 14,8% of exams, using gadopentate-dimeglumine to assist the differentiation from epidural fibrosis; infections like spondylodiscitis and abscess in 12,5%. Other findings included arachnoiditis, pseudomeningoceles and seromas. Conclusions: MRI is a useful method to study the postoperative lumbar spine, specially when enhanced with gadopentate-dimeglumine. Enhanced images can differentiate two of the major complication like epidural fibrosis, and recurrent disc herniation. Spondylodiscitis are important and frequent too. Although the findings of complications in our series in the postoperative lumbar spine represent 92,18 %, these not always explain the symptomatology. Therefore, the interrelation is important with the surgeon to determine which abnormalities are clinically significant.

Las técnicas nofarmacológicas se mostraron extremadamente útiles, sin embargo es necesario que los padres sean estimulados a participar activamente en el manejo del dolor de sus hijos.Considering the harmful effects of the postoperative pain on children and their right to get relief, there is a need to research this subject. Qualitative study developed at a pediatric unit of a public hospital in Londrina-Paraná, aims to analyze the parent's perception about the postoperative pain management by the nursing team and their involvement in this process. Ten parents of children that were submitted to surgeries were interviewed. Data were grouped in two themes: characterization of the postoperative pain management and strategies used to get relief of postoperative pain. Pharmacological therapy was considered the main method used by the nursing team to analgesia. Concerning the parent's actuation, they referred nonpharmacological strategies such as: distraction, use of toys, among others. Pharmacological treatment is overestimated by professionals and parents. Non-pharmacological techniques have proved useful. However, it is necessary to encouraged the parents to participate in the pain management of their children.

    Full Text Available La lipoaspiración, técnica tradicional usada para el tratamiento de las lipodistrofias con cicatrices mínimas, ha sido a través de los años mejorada con los avances anestésicos, farmacológicos y de instrumental. A su vez han aparecido otras técnicas que han publicitado ventajas respecto al tiempo de recuperación, sintomatología y resultados estéticos. Una de estas técnicas es la laserlipolisis a la que se atribuye menos dolor, menos equimosis y rápido postoperatorio. No se encuentran trabajos que acrediten estas ventajas, por lo que decidimos estudiar si existen ventajas de laserlipolisis en comparación con la lipoaspiración tradicional respecto del dolor, síntoma importante a considerar en el postoperatorio. Para esto se diseñó un trabajo prospectivo randomizado con una muestra de 60 pacientes a los cuales se aplicaron las dos técnicas en diferentes áreas y al mismo paciente. Se evaluó el dolor con escala numérica analógica a las 4 horas, 48 horas y 5 días de postoperatorio. Los resultados mostraron que la laserlipolisis presenta menos dolor en los muslos medido a las 48 horas y 5 días de la intervención. No hay diferencias entre estas dos técnicas en las otras zonas medidas como abdomen, áreas pretrocantéreas ("alforjas", zona lumbar y pectoral. Considerando todos los pacientes sin diferenciar la técnica usada, las "alforjas" a las 4 horas duelen menos que el abdomen y a los 5 días duelen menos los muslos que el abdomen. No encontramos relación entre volumen aspirado e intensidad del dolor.The traditional suction-assisted lipoplasty, is a well established and commonly performed technique used for the treatment of lipodystrophias, which has undergone improvements with advances in anesthetics, pharmacology and introduction of new instruments.

    Full Text Available Mussels are one of the most cultivated and commercialized bivalves worldwide and in southern Chile its culture represent an important economic activity. The species identification within the Mytilus genera, by morphological features, is unreliable, so we used a polymorphism RFLP in the gene encoding the polyphenolic adhesive protein as a species-specific genetic marker to describe Mytilus species diversity in southern Chile, and evaluate possible applications in traceability, food quality and safety. Using Me 15-16 marker most mussels were M. chilensis, finding no other pure individuals; however, putative hybrids of M. chilensis x M. trossulus and M. chilensis x M. galloprovincialis were detected. There was no evidence of M. edulis. The presence of the M. trossulus allele, faraway from its distribution area, demands further analysis with different genetic markers to allow a better understanding of its origin. In addition, the correspondence between markers that distinguishes northern from southern hemisphere M. galloprovincialis, with those who discriminates between M. chilensis and M. galloprovincialis would contribute to the taxonomic status of Chilean blue mussels. In Chile, the genetic composition of Mytilus indicates that geographical origin of mussels and its traceability cannot be established merely from the identification of the species. The use of other markers would be required.Los mejillones son una de las especies de bivalvos más cultivadas y comercializadas, en el sur de Chile donde su cultivo representa una actividad económica importante. La identificación de la especie dentro del género Mytilus, basada en las características morfológicas no es confiable por lo que se utilizó un polimorfismo RFLP en el gen que codifica la proteína adhesiva polifenólica como marcador genético específico de la especie para describir la diversidad de especies Mytilus en el sur de Chile, y evaluar posibles aplicaciones en trazabilidad

Uplift/cooling ages of these rocks, and local Devonian shallow-water cover sequences suggest that final consolidation of the basement occurred through Late Paleozoic time. A necessary consequence of this process would have been contemporaneous erosion and the substantial development of marine sedimentary basins at the Pacific margin of Zealandia. These are found nowhere at the present day, suggesting that the basins have been lost by tectonic erosion, perhaps in a margin-parallel dextral translation similar to late Paleozoic-Mesozoic suspect terranes of New Zealand. Aprobable detrital zircon age pattern is assembled for these lost Zealandia sediments, and then compared with those of pre-Jurassic (probable Triassic to Devonian metasedimentary rocks in the Chilean archipelago. Significant Mesoproterozoic, latest Neoproterozoic-Cambrian and Devonian-Carboniferous detrital zircon age components are common to both, thus supporting a possible Chilean terrane destination for these 'lost terranes of Zealandia'.Las sucesiones metasedimentarias del Precámbrico tardío al Ordovícico y granitoides del Cámbrico-Ordovícico y Devónico-Carbonífero constituyen la mayor parte del basamento del sur de Zealandia y sectores adyacentes de la Antartica y el sudeste de Australia. Las edades de enfriamiento/alzamiento de estas rocas y la cobertura local de secuencias de aguas someras del Devónico, sugieren que la consolidación definitiva del basamento se produjo durante el Paleozoico tardío. Una consecuencia necesaria de este proceso habría sido la erosion contemporánea y el desarrollo sustancial de cuencas sedimentarias marinas en el margen del Pacífico de Zealandia. Estas no se encuentran en ninguna parte en la

La investigación fue efectuada buscando establecer un marco de referencia ambiental para este organismo. La concentración metálica siguió el orden: Hg We analyzed the heavy metal content in the muscular tissue of the catfish, Ariopsis felis, in the southern Gulf of México between 2001 and 2004. The research was done in order to establish an environmental frame of reference for this organism. The metal concentration was as follows: Hg < Co < Pb < Ni < V < Cr. Cobalt and vanadium contents were found to decrease and those of nickel, mercury, and chromium to ulerease; however, neither of these trends was observed for the lead content. One-way analyses of variance con-firm significant temporal variation only for cobalt, mercury, lead, and vanadium. Significant linear correlation coefficients (p ≤ 0.05 were found for Co-V, Cr-Ni, Cr-Pb, Co-Hg, Ni-V, and V-Pb. The first three associa-tions showed positive correlations, whereas the remaining ones had negative correlations. A factor analysis grouped the studied metals depending on their origins. The metal levels found in the muscular tissue of A. felis from the southern Gulf of México were lower than those set by national and international regulations.

    Full Text Available Taxonomically, the Mollusca of the southern end of South America are moderately well known, but the literature is scattered, there is little information on their habitats, and distributional records are scarce for the Chilean archipelago lying between Chiloé Island (42° S and Tierra del Fuego (55° S. Although much is known about the biology and ecology of of some species of Nacellidae, the taxonomy of the group have been partially neglected, particularly in remote areas of the world such as the Chilean fjords. Therefore, this study aims to clarify the nomenclatural status, and establish the morphological characteristics and distribution of the Chilean Nacellidae. Especially, the following three objectives are pursued: (i to clarify the correct identity of existing species; (ii to describe of morphological details, highlighting the clear diagnostic characters of each species, and (iii to delimitate and discuss their geographical range in Chile. The examination of the Nacellidae of the Chilean fiords has resulted in the recognition of one species of Nacella (Nacella and seven species of Nacella (Patinigera, wherein the principal specific differences are in the shell (shape, thickness and color and in radular teeth morphology. The genus Nacella and its subgenus Patinigera are cold-water limpets, and are exclusively inhabitants of Subantarctic and Antarctic waters.

METHODS: A quantitative, exploratory study of a sample of 211 hypertensive, older adults (29.1% of those being treated by the cardiovascular program at the Centro de Salud Familiar San Pedro, in the province of Concepción, del Bío Bío region, Chile. Seven instruments were applied: Pfeiffer's short mental status questionnaire, Yesavage's geriatric depression scale, the elder abuse screening scale, the morale scale of the Philadelphia Geriatric Center, the health behavior scale, the Lawton assessment of instrumental activities of daily living (ADL, and the Katz ADL index. Following an analysis of the important components, latent variables were identified. RESULTS: Two latent variables were identified: social connectedness-measured by the variables depression, abuse, and social satisfaction-and autonomy-measured by the variables mental health and ability to perform basic and instrumental ADLs. These latent variables accounted for 39.7% and 20.7% of nonadherence to therapy, respectively. CONCLUSIONS: The latent variables proposed here can be used as predictive factors for therapy nonadherence in elderly adults with arterial hypertension. Causes of nonadherence to therapy cannot be assessed solely at health care centers; but rather, an understanding of the home environment is needed and treatment should be adapted according to the needs that exist there.

    2009-12-01

    Sexual pain is an underrecognized and poorly treated constellation of disorders that significantly impact affected women and their partners. Recognized as a form of chronic pain, sexual pain disorders are heterogeneous and include dyspareunia (superficial and deep), vaginismus, vulvodynia, vestibulitis, and noncoital sexual pain disorder. Women too often tolerate pain in the belief that this will meet their partners' needs. This article provides a review of the terminology and definition of the condition, theories on the pathophysiology, diagnostic considerations, and recommendations on the management of female sexual pain.

    The Laguna del Maule Volcanic Field, Chile, includes an unusually large and recent concentration of silicic eruptions. Since 2007 the crust here has been inflating at an astonishing rate of 25 cm/yr. Findings thus far lead to the hypothesis that the silicic vents have tapped an extensive layer of crystal-poor, rhyolitic melt that began to form atop a magmatic mush zone that was established by ~20 ka with a renewed phase of rhyolite eruptions during the Holocene. Modeling of surface deformation, magnetotelluric data, and gravity changes suggest that magma is currently intruding at a depth of ~5 km. Swarms of volcano-tectonic and long period earthquakes, mostly of M San Juan-Argentina, Nanyang Technological University-Singapore, SERNAGEOMIN, OVDAS, USGS, and SEGEMAR-Argentina. Team members will be introduced in this presentation. Our approach includes augmenting the OVDAS array of 6 permanent seisic stations with 40 additional instruments to conduct tomographic, receiver function and ambient noise studies. We continue to collect 4-D gravity data from 37 stations. Surface deformation is monitored via cGPS at 5 permanent receivers and InSAR data. A magnetotelluric survey across the Andes at 36o S is planned. Geochemical studies include mineral zoning and U-Th disequilibrium of zircons to constrain the timing of magma intrusion and mixing events prior to the current unrest. The overall aim is to integrate these observations and to construct numerical models of system dynamics. We are developing communications protocols and a web site to facilitate sharing of findings among the team members and with the public.

LBP is more often idiopathic. It has as most frequent cause the internal disc disruption (IDD) and is referred to as discogenic pain. IDD refers to annular fissures, disc collapse and mechanical failure, with no significant modification of external disc shape, with or without endplates changes. IDD is described as a separate clinical entity in respect to disc herniation, segmental instability and degenerative disc desease (DDD). The radicular pain has as most frequent causes a disc herniation and a canal stenosis. Both discogenic and radicular pain also have either a mechanical and an inflammatory genesis. For to be richly innervated, facet joints can be a direct source of pain, while for their degenerative changes cause compression of nerve roots in lateral recesses and in the neural foramina.

METHODS: Cross-sectional cluster survey covering 1 730 women aged 20 years or older with a history of sexual activity. Information was collected on social, demographic and behavioral variables, knowledge of and use of the Pap test. RESULTS: Of women aged 25-59 years, who are the target population of the national cervical cancer screening program, 78.7% had had at least one Pap test in their lifetime, and 68.8% had had a Pap test in the last 3 years. Statistics for focus of the program showed that of the 637 women who reported having a Pap test in the last year, only 20.6% actually required one. The remainder were either outside the age range or had had another test less than 30 months previously. Prevalence of not having been tested in the previous 3 years was highest among black (41.7% and low-income women (64.3%, and among those at greatest risk for cervical cancer (62.3% for women with three or more risk factors. Focus was inversely related to socioeconomic status. CONCLUSION: Coverage rates were similar to those reported in other national studies, but this is the first report to examine the focus of the national program. We show that 8 of every 10 Pap tests were not necessary. Coverage levels remain unacceptably low among women of low socioeconomic status and those at greatest risk for cervical cancer.OBJETIVO: Determinar la cobertura y la concentración poblacional del tamizaje del cáncer cervicouterino (con la prueba de Papanicolaou en una muestra poblacional en el Brasil.

    Full Text Available Pain, which afflicts up to 20% of the population at any time, provides both a massive therapeutic challenge and a route to understanding mechanisms in the nervous system. Specialised sensory neurons (nociceptors signal the existence of tissue damage to the central nervous system (CNS, where pain is represented in a complex matrix involving many CNS structures. Genetic approaches to investigating pain pathways using model organisms have identified the molecular nature of the transducers, regulatory mechanisms involved in changing neuronal activity, as well as the critical role of immune system cells in driving pain pathways. In man, mapping of human pain mutants as well as twin studies and association studies of altered pain behaviour have identified important regulators of the pain system. In turn, new drug targets for chronic pain treatment have been validated in transgenic mouse studies. Thus, genetic studies of pain pathways have complemented the traditional neuroscience approaches of electrophysiology and pharmacology to give us fresh insights into the molecular basis of pain perception.

    Within the context of treatment of metastatic bone pain with bone seeking radiopharmaceuticals, this paper expounds the results of an analysis of available molecules (both approved for clinical use or still under study) intended to obtain a detailed comparison of their dosimetric characteristics. These can be used to supplement the list of already know differences between them, such as efficacy, appearance and length of the palliative effect, eventual tumoricidal effect, myelotoxicity, sale price and availability. Seven radiopharmaceuticals have been analysed, five of them are based on beta emission radionuclides: {sup 3}2P, {sup 1}53Sm, {sup 1}86Re and {sup 1}88Re and the other two ones are based on high Linear energy Transference emission radionuclides: {sup 1}17mSn and {sup 2}23Ra a series of estimates of the main dosimetric parameters for each radiopharmaceutical analysed have been obtained. The values obtained might be worth being incorporated to the risk/benefit analysis that precedes every choice of the specific radiopharmaceutical to be used with an individual patient. In this way, we hope these results will be of some help for those Nuclear Medicine specialists interested in the treatment of oncological bone pathologies. (Author)

    Full Text Available Neuropathic pain is the expression of a dysfunction or primary lesion of a nerve in the peripheral or central nervous system, or both, rather than the biological signal transmitted by the nerve following peripheral nociceptor activation. It represents about 20% of all painful syndromes, with an estimated prevalence of 1.5%, however is actual incidence is hard to pinpoint due to the difficulties encountered in distinguishing it from chronic pain, of which it represents a significant percentage, on account of the not infrequent concurrence of conditions. It is crucial to recognise the variety of symptoms with which it can present: these can be negative and positive and, in turn, motor, sensitive and autonomic. In public health terms, it is important to emphasise that the diagnosis of neuropathic pain does not in most cases require sophisticated procedures and does not therefore weigh on health expenditure. In clinical practice, a validated scale (the LANSS is mentioned is useful for identifying patients presenting neuropathic pain symptoms. Therapy is based on three categories of medication: tricyclic antidepressants, anti-epileptics and opioids at high doses: neuropathic pain has a bad reputation for often resisting common therapeutic approaches and responding less well that nociceptor pain to monotherapy. Therapeutic strategies are all the more adequate the more they are based on symptoms and therefore on the pain generation mechanisms, although the recommendations are dictated more by expert opinions that double-blind randomised trials.

    Full Text Available Abstract Background Osteoarthritis (OA is one of the main causes of disability worldwide, especially in persons >55 years of age. Currently, controversy remains about the best therapeutic alternative for this disease when evaluated from a cost-effectiveness viewpoint. For Social Security Institutions in developing countries, it is very important to assess what drugs may decrease the subsequent use of medical care resources, considering their adverse events that are known to have a significant increase in medical care costs of patients with OA. Three treatment alternatives were compared: celecoxib (200 mg twice daily, non-selective NSAIDs (naproxen, 500 mg twice daily; diclofenac, 100 mg twice daily; and piroxicam, 20 mg/day and acetaminophen, 1000 mg twice daily. The aim of this study was to identify the most cost-effective first-choice pharmacological treatment for the control of joint pain secondary to OA in patients treated at the Instituto Mexicano del Seguro Social (IMSS. Methods A cost-effectiveness assessment was carried out. A systematic review of the literature was performed to obtain transition probabilities. In order to evaluate analysis robustness, one-way and probabilistic sensitivity analyses were conducted. Estimations were done for a 6-month period. Results Treatment demonstrating the best cost-effectiveness results [lowest cost-effectiveness ratio $17.5 pesos/patient ($1.75 USD] was celecoxib. According to the one-way sensitivity analysis, celecoxib would need to markedly decrease its effectiveness in order for it to not be the optimal treatment option. In the probabilistic analysis, both in the construction of the acceptability curves and in the estimation of net economic benefits, the most cost-effective option was celecoxib. Conclusion From a Mexican institutional perspective and probably in other Social Security Institutions in similar developing countries, the most cost-effective option for treatment of knee and/or hip OA

    Full Text Available A sequence of 150 explosive eruptions recorded during the past century at the Chilean Southern Volcanic Zone (SVZ is subjected to statistical time series analysis. The exponential, Weibull, and log-logistic distribution functions are fit to the eruption record, separately for literature-assigned volcanic exploslvlty indices (VEI ≥ 2 and VEI ≥ 3. Since statistical tests confirm the adequacy of all the fits to describe the data, all models are used to estimate the likelihood of future eruptions. Only small differences are observed between the different distribution functions with regard to the eruption forecast, whereby the log-logistic distribution predicts the lowest probabilities. There is a 50% probability for VEI ≥ 2 eruptions to occur in the SVZ within less than a year, and 90% probability to occur within the next 2-3 years. For the larger VEI ≥ 3 eruptions, the 50% probability is reached in 3-4 years, while the 90% level is reached in 9-11 years.Se presenta un análisis estadístico de la serie temporal de 150 erupciones volcánicas explosivas registradas durante el siglo pasado en la Zona Volcánica del Sur de Chile. Se modeló el conjunto de erupciones mediante la distribución exponencial, de Weibull y log-logística, restringiendo el análisis a erupciones de índice de explosividad volcánica (IEV mayores a 2 y 3, respectivamente. Como los modelos pasan las pruebas estadísticas, los tres modelos se aplican para estimar la probabilidad de erupciones futuras. Se observan solo diferencias menores entre las predicciones mediante los distintos modelos, con la distribución log-logística dando las probabilidades más bajas. Para erupciones de IEV ≥ 2, la probabilidad de producirse una erupción dentro de un año es más del 50%, creciendo al 90% en 2-3 años. Para erupciones más grandes, de IEV ≥ 3, el 50% de probabilidad se alcanza dentro de 3-4 años, y el 90% dentro de 9-11 años.

Los resultados mostraron que el modelo propuesto se adaptó de manera significativa a los datos (con 3% de error máximo, por lo tanto, los parámetros obtenidos pueden considerarse los correspondientes al modelo para el tipo de suelo y estación del año correspondiente.The fertilization efficiency program in pasture systems for improving livestock feeding is very important for for farmers in southern Chile. This paper reformulates a mathematical simulation model proposed to describe the concentration of total nitrogen (NT in soil, in order to fit real experimental data. The objective was to determine the appropriate fertilization strategies in pastures and their direct use by livestock. Critical assumptions consisted, first, in that the concentration of TN in the soil depends on the concentration of its three major components: organic nitrogen (N-NO, nitrate nitrogen (N-NO3- and ammonium nitrogen (N-NH4+ and second, that the behavior of the concentration of these components depends strongly on the season of the year and, therefore, the coefficients in the model must be different for each season and third, that only the first 10 cm of the soil profile are meaningful for pasture growth. The modified model consists of a system of partial differential equations (PDE, which consists of EDP's for N-NO and N-NO3-, while N-NH4+ was interpolated by a polynomial with the degree varying with the season. The model parameters were calculated solving a functional least squares sum of residuals, using the experimental data. We used optimization methods to solve the problem of least squares. The model used initial data and boundaries approximated by polynomials for each season of the year. The resulting parameters were two: A Quasi-Newton (BFGS and a Genetic Algorithm (GA.

    Effective management of procedural and postoperative pain in neonates is required to minimize acute physiological and behavioral distress and may also improve acute and long-term outcomes. Painful stimuli activate nociceptive pathways, from the periphery to the cortex, in neonates and behavioral responses form the basis for validated pain assessment tools. However, there is an increasing awareness of the need to not only reduce acute behavioral responses to pain in neonates, but also to protect the developing nervous system from persistent sensitization of pain pathways and potential damaging effects of altered neural activity on central nervous system development. Analgesic requirements are influenced by age-related changes in both pharmacokinetic and pharmacodynamic response, and increasing data are available to guide safe and effective dosing with opioids and paracetamol. Regional analgesic techniques provide effective perioperative analgesia, but higher complication rates in neonates emphasize the importance of monitoring and choice of the most appropriate drug and dose. There have been significant improvements in the understanding and management of neonatal pain, but additional research evidence will further reduce the need to extrapolate data from older age groups. Translation into improved clinical care will continue to depend on an integrated approach to implementation that encompasses assessment and titration against individual response, education and training, and audit and feedback.

    Roca, J; Valero, R; Gomar, C

    Postoperative pain after cardiac surgery (CS) can be generated at several foci besides the sternotomy. Prospective descriptive longitudinal study on the chronological evolution of pain in 11 sites after CS including consecutive patients submitted to elective CS through sternotomy. The primary endpoints were to establish the main origins of pain, and to describe its chronological evolution during the first postoperative week. Secondary endpoints were to describe pain characteristics in the sternotomy area and to correlate pain intensity with other variables. Numerical Pain Rating Scale from 0 to 10 at rest and at movement on postoperative days 1, 2, 4 and 6. Numerical Pain Rating Scale>3 was considered moderate pain. Statistical analysis consisted in Mann-Whitney U-test, a Chi-squared, a Fisher exact text and Pearson's correlations. Forty-seven patients were enrolled. In 4 of 11 locations pain was reported as Numerical Pain Rating Scale>3 (sternotomy, oropharynx, saphenectomy and musculoskeletal pain in the back and shoulders). Maximum intensity of pain on postoperative days 1 and 2 was reported in the sternotomy area, while on postoperative days 4 and 6 it was reported at the saphenectomy. Pain at rest and at movement differed considerably in the sternotomy, saphenectomy and oropharynx. Pain at back and shoulders and at central venous catheter entry were not influenced by movement. Pain in the sternotomy was mainly described as oppressive. Patients with arthrosis and younger patients presented higher intensity of pain (P=.004; P=.049, respectively). Four locations were identified as the main sources of pain after CS: sternotomy, oropharynx, saphenectomy, and back and shoulders. Pain in different focuses presented differences in chronologic evolution and was differently influenced by movement.

    Full Text Available The relative abundance and fishing potential of the commercially valuable fishes and cephalopods with marketable size was assessed using two seasonal bottom trawl surveys performed in 2001 and 2002 on the outer shelf and upper slope (100-600 m depth off the coast of southern Brazil. These surveys were part of REVIZEE, a national program designed to assess the fishery potential within the Economic Exclusive Zone. Of the 228 fish and cephalopod species caught during the surveys, only 27 species and genera were considered to be of commercial interest. Commercial-sized individuals of these species made up 52.3% of the total catch. The total biomass was estimated to be 167,193 ton (± 22% and 165,460 ton (± 25% in the winter-spring and summer-autumn surveys, respectively. The most abundant species were the Argentine short-fin squid Illex argentinas, a species with highly variable recruitment, followed by the Argentine hake Merluccius hubbsi, the gulf-hake Urophycis mystacea, and the monkfish Lophius gastrophysus. The latter three were intensively fished prior to the surveys, as well as the beardfish Polymixia lowei and silvery John dory Zenopsis conchifera, both relatively abundant but with a very low market value. The potential yield of the demersal fish species, not considering Illex argentinus, estimated with the Gulland equation for a mean natural mortality of M = 0.31, was 20,460 ton. When considering only Merluccius hubbsi, Urophycis mystacea, and Lophius gastrophysus, the potential yield decreased to 6,625 ton. The surveys showed that the fishery potential of the outer shelf and upper slope was substantially lower than that of the inner shelf. Therefore, this environment should be carefully monitored to avoid overfishing and fast depletion.Se evaluó la abundancia relativa y el potencial pesquero de peces y cefalópodos de especies y tamaños de valor comercial en dos muéstreos estacionales con redes de arrastre de fondo realizados en los a

  2. Southern blotting.

    Southern blotting is the transfer of DNA fragments from an electrophoresis gel to a membrane support (the properties and advantages of the different types of membrane, transfer buffer, and transfer method are discussed in detail), resulting in immobilization of the DNA fragments, so the membrane carries a semipermanent reproduction of the banding pattern of the gel. After immobilization, the DNA can be subjected to hybridization analysis, enabling bands with sequence similarity to a labeled probe to be identified. This appendix describes Southern blotting via upward capillary transfer of DNA from an agarose gel onto a nylon or nitrocellulose membrane, using a high-salt transfer buffer to promote binding of DNA to the membrane. With the high-salt buffer, the DNA becomes bound to the membrane during transfer but not permanently immobilized. Immobilization is achieved by UV irradiation (for nylon) or baking (for nitrocellulose). A Support Protocol describes how to calibrate a UV transilluminator for optimal UV irradiation of a nylon membrane. An alternate protocol details transfer using nylon membranes and an alkaline buffer, and is primarily used with positively charged nylon membranes. The advantage of this combination is that no post-transfer immobilization step is required, as the positively charged membrane binds DNA irreversibly under alkaline transfer conditions. The method can also be used with neutral nylon membranes but less DNA will be retained. A second alternate protocol describes a transfer method based on a different transfer-stack setup. The traditional method of upward capillary transfer of DNA from gel to membrane described in the first basic and alternate protocols has certain disadvantages, notably the fact that the gel can become crushed by the weighted filter papers and paper towels that are laid on top of it. This slows down the blotting process and may reduce the amount of DNA that can be transferred. The downward capillary method described in

    écnica. La solución anestésica no deberá ser inyectada para evitar una posible lesión de la raíz nerviosa o de la médula espinal. Se debe retroceder la aguja y alterar su dirección antes de nuevo avance. El relato de dolor es totalmente imposible si el paciente está adormecido bajo influencia de la anestesia general y, por este motivo, es recomendable que bloqueos sean realizados con el paciente consciente. El dolor solamente es referido cuando la punta de la aguja o la punta del catéter se desvían del plano medio sagital para alcanzar el compartimiento peridural antero-lateral, pudiendo, de esta forma tocar las radículas nerviosas situadas próximas a los forames intervertebrales. Excluyéndose los estudios sobre la inervación de la piel, del tejido celular subcutáneo y del ligamento interespinoso, el objetivo de este trabajo es el de rever la inervación de algunas estructuras del canal vertebral: del ligamento amarillo, del ligamento longitudinal posterior, de la dura-máter y del disco intervertebral.

Vessel motion data (pitch and roll were registered in situ using a digital clinometer and used to correct the nautical area scattering coefficients (NASC in elementary sampling units of 926 m distance by 10 m depth. These NASC correction factors (NASCcp were calculated using Dunford's algorithm for circular transducers. We found high variability in NASCcp, which averaged 12%, and ranged between 0 and 50%. NASCcp variability was explained significantly by the mean depth of the integrated stratum (33%, the weather condition, as measured by Beaufort's scale (5%, and the vessel course relative to wind direction (2%. The empirical model we used to explain NASC Cp variability may be suitable for correcting bias due to transducer motion in other, past and future, fisheries acoustic surveys targeting mid-water species under rough weather conditions.Se evaluó la pérdida de sensibilidad producida por el movimiento de un transductor montado en el casco y sus efectos sobre la abundancia y biomasa estimada de merluza de tres aletas (Micromesistius australis en un estudio acústico realizado en el Pacífico suroriental, frente a la costa de Chile, durante el invierno austral de 2009.

    In emergency departments, chest pain is one of the leading motives of consultation. We thus consider it important to review aspects such as its classification, causes, and clinical profiles. Initial assessment should include a full clinical history comprising thorough anamnesis and physical examination. Adequate interpretation of auxiliary tests, ordered in accordance with suspected clinical conditions, should lead to accurate diagnosis. We highlight certain symptoms and clinical signs, ECG and X-ray findings, cardiac bio markers, arterial blood gases, and CT-scanning. Scores of severity and prognosis such as TIMI are assessed. Optimal treatment of the clinical conditions leading to chest pain depends on adequate initial approach and assessment.

Escapes of Oncorhynchus tshawytscha (Chinook salmon from aquaculture after 1990 have apparently produced increasingly important reproductive returns "naturalized", to upper basins in Chile and Argentina south of 39º S. In this paper we show data on the historic and spatial occurrence of chinook salmon in four Pacific basins during the past decade. Our objective is to establish the progress of the settlement forecasting some ecosystem disruptions in order to project and manage potential impacts. In Chile, sampling took place from 1995 to 2005 including rivers Petrohué, Poicas, and Río Negro-Hornopiren, and Lake Puyehue, in the X Region. In Argentina sampled rivers were Futaleufú, Carrenleufú and Pico. In Chile and Argentina reproductive Chinooks ranged in size between 73 and 130 cm total length, being the smallest sizes those of Lake Puyehue where the population is apparently landlocked. In Río Petrohué, the size of the runs varied from year to year reaching in the peak season of 1996 and 2004 up to 500 kg of fish along 100 m of riverbank. Temporal distribution of juvenile Chinooks suggested mainly a typical ocean type as they are gone to sea within the first year of age. As seen in Petrohue, reproductive populations could import significant quantities of marine derived nutrients as they do in their original habitats thus disturbing natural cycles and balances. Chinook establishment in these pristine watersheds in southern South America poses new challenges for decision makers and fishermen since they may develop a fishery in the Pacific Ocean with consequences to other fishery resources. Additionally they also become a resource for sport fishing. Therefore there is the need of developing

Se identificaron 64 familias. El número de familias, la abundancia y diversidad biológica disminuyó con la profundidad. La distancia a los bancos y arrecifes determinan la variación en la riqueza de familias y la distribución de la asociación de macrocrustáceos. El banco de Campeche puede considerarse un hotspot de diversidad biológica marina para los macrocrustáceos asociados a fondos carbonatados.This study contributes with information on the number of families, abundance, biodiversity and geographical distribution of the crustacean assemblage associated to carbonated habitats in the western sector of the Campeche Bank. The samples studied were collected onboard the R/V Pelican of the University of Louisiana from dredge materials obtained at a range of 20 to 182 m depth. The specimens were grouped into 64 families. The number of families, the abundance and diversity values decreased with increasing depth. The distance to the banks and reef islands determined the variability recorded in the richness of families and the distribution patterns of the macrocrustacean assemblage. The Campeche Bank is suggested to be a "hotspot" of biological diversity for the macrocrustaceans associated to the carbonated bottoms.

    This chapter focuses on what social pain is and how it should be managed. In order to understand social pain in a cancer patient, it is necessary to recognize the change in the patient's daily life after the diagnosis of cancer. Because the degree of suffering and the relationships with family members and the people he or she worked with differ from patient to patient, it is important to note that the context of social pain is different in each patient. Five points shown below are essential in managing social pain. 1. Economical suffering may be alleviated by utilization of the social security system while taking into account each patient's standard of living. 2. Burdens on family members should be lessened, such as by not having them stay at the patient's bedside every day and letting them go home occasionally. 3. The normal patterns of communication, support, and conflict in the family should be identified, and the extent to which they have been disrupted by the illness should be assessed. 4. It is important to understand the ethnic, cultural, and religious background of the patient and the potential impact of their influence on the individual and the illness. 5. Practical or emotional unfinished business that the patient has needs to be identified, and efforts should be made to support fulfillment.

    Full Text Available In the primary care sector, diagnosis and initial management of orofacial pain are often performed by familydoctors and dentists. Knowledge of the different types of orofacial pain and headache disorders is therefor of great importance. The International Classification of Headache Disorders (ICHD-3 provides an overview of the different types of orofacial pain and will be discussed in this lecture. The main focus will be on trigeminal neuralgia and cluster headache and the current research in this field. Trigeminal Neuralgia (TN is defined as a disorder characterized by recurrent, unilateral, brief, electricshock-like pains, abrupt in onset and termination, limited to the distribution of one or more divisions of thetrigeminal nerve and triggered by innocuous stimuli. Unfortunately, most TN is idiopathic, and the aetiology isnot clear. The guidelines on pharmaceutical TN management published by the American Academy of Neurology (AAN and the European Federation of Neurological Societies (EFNS recommend carbamazepine (CBZ; 200–1200 mg/day or oxcarbazepine (OXC; 600–1800 mg/day as first-line therapy. Both are antiepileptics with well known interactions with other drugs and safety problems. An overview of the currently available literature on the pharmaceutical management of TN patients is discussed. Cluster headache (CH is one of the most painful primary headache disorders. It is characterized by daily or almost daily attacks of unilateral excruciating periorbital pain associated with ipsilateral cranial autonomic symptoms, typically lasting between 15 and 180 minutes if untreated. Cluster headache is caused by the relaesement of neurotransmitters and vasodilators from the sphenopalatine ganglion (SPH. The SPG is a large extracranial parasympathetic ganglion located in the pterygopalatine fossa (PPF. The current treatments for CH attacks are injectable sumatriptan and oxygen inhalation. Both treatments have well known side effects and

    Despite evidence that many nursing home residents' pain is poorly managed, reasons for this poor management remain unanswered. The aim of this study was to determine if specific order sets related to pain assessment would improve pain management in nursing home (NH) residents. Outcomes included observed nurse pain assessment queries and resident reports of pain. The pretest/post-test study was performed in a 240-bed for-profit nursing home in the mid-southern region of the United States and participants were 43 nursing home residents capable of self-consent. Medical chart abstraction was performed during a 2-week (14-day) period before the implementation of specific order sets for pain assessment (intervention) and a 2-week (14-day) period after the intervention. Trained research assistants observed medication administration passes and performed participant interviews after each medication pass. One month after intervention implementation, 1 additional day of observations was conducted to determine data reliability. Nurses were observed to ask residents about pain more frequently, and nurses continued to ask about pain at higher rates 1 month after the intervention was discontinued. The proportion of residents who reported pain also significantly increased in response to increased nurse queries (e.g., "Do you have any pain right now?"), which underscores the importance of nurses directly asking residents about pain. Notably 70% of this long-stay NH population only told the nurses about their pain symptoms when asked directly. Findings uncover that using specific pain order sets seems to improve the detection of pain, which should be a routine part of nursing assessment.

Para cada una de ellas se estimó la diversidad gamma, el porcentaje de endemismo, el valor filogenético y la complementariedad, exceptuando Juan Fernández del cual no se pudo obtener ningún valor filogenético. El cálculo del valor filogenético se realizó a través del uso de cuatro índices, el valor filogenético sin ninguna modificación (W, considerando la endemicidad (We, y sus respectivas estandarizaciones (Ws y Wes. Los resultados muestran que la estandarización del valor filogenético (Ws produce un sesgo cuando los cladogramas difieren en tamaño y que el complemento entre áreas es una herramienta secundaria de gran utilidad. Sin embargo, los resultados muestran que para determinar la importancia de las áreas, el complemento debe ser usado en conjunto con la diversidad específica y la endemicidad. Las comparaciones de los resultados obtenidos usando W, We y análisis de complementariedad estrictos y modificados muestran que el valor filogenético que admite endemicidad (We puede ser aplicado como único valor para determinar la importancia de cada área. Aplicando We, las seis primeras áreas seleccionadas acumulan el 72 % del valor filogenético y el 74 % de la diversidad gamma de los carábidos de América del Sur austral, mientras que ninguno de los otros parámetros usados acumula el 70 % de las especies antes de sumar la séptima área. Las seis áreas seleccionadas son la Selva valdiviana, las Sierras pampeanas, Coquimbo, Patagonia occidental, Chile central y La Araucanía.

This study reports on the health status of the four southern Arizona border counties. METHODS: Data on health indicators for Cochise, Pima, Santa Cruz, and Yuma Counties were collected from the Arizona Department of Health Services Vital Records and Statistics. Progress was calculated as a percentage made toward or away from the 2010 target. Comparisons were made between the border counties and Arizona. RESULTS: Progress toward the HB 2010 targets varied among the border counties. All border counties made progress toward the targets with the cervical cancer, hepatitis A, and teenage birthrate objectives. Most border counties moved toward the goals for breast cancer, diabetes mortality, tuberculosis, motor vehicle crashes, infant mortality from congenital abnormalities, and prenatal care. Border counties moved away from the target with the human immunodeficiency virus and infant mortality objectives. CONCLUSIONS: Assessment of the HB 2010 objectives provided a comprehensive description of the health status of the population. Although the southern Arizona border counties have shown improvement in some areas, monitoring is still needed to identify the disparities that remain.OBJETIVO: La región estadounidense de la frontera entre México y los Estados Unidos consta de 48 condados distribuidos en cuatro estados, y las poblaciones que viven a uno y otro lado de la frontera tienen problemas de salud similares.

Se estimó el porcentaje de luz difusa, la disponibilidad de nitrógeno, fósforo y calcio, el contenido de nitrógeno, fósforo y calcio de la hojarasca, y se determinó la composición de la regeneración avanzada bajo los doseles de cada una de las cuatro especies. Además, se realizó una ordenación para evaluar la variación de la composición de la regeneración avanzada. Se encontraron diferencias significativas en la transmisión de luz bajo cada especie, así como en el contenido nutricional de la hojarasca y disponibilidad de los nutrientes N-NO3 y P. Los tres nutrientes evaluados presentaron escasa disponibilidad en el suelo, debido a baja mineralización y alta inmovilización. De acuerdo a la ordenación, la composición de la regeneración avanzada bajo N. dombeyi y L. philippiana, fue distinguible de la composición de la regeneración bajo E. cordifolia y A. punctatum. La luz fue el recurso que explicó la mayor parte de la variación en la composición de la regeneración avanzada en el sotobosque.

Oxytocine was administered in 81% of cases, but 15% did not receive any medication. A significant difference was observed in pain relief after using non-pharmacological strategies, showing reduced pain as cervix dilation increased. It was concluded that the strategies were effective in reducing the intensity of pain in the studied parturients in labor.

  19. Pain and the ethics of pain management.

    Science.gov (United States)

    Edwards, R B

    1984-01-01

    In this article I clarify the concepts of 'pain', 'suffering', 'pains of body', 'pains of soul'. I explore the relevance of an ethic to the clinical setting which gives patients a strong prima facie right to freedom from unnecessary and unwanted pain and which places upon medical professionals two concomitant moral obligations to patients. First, there is the duty not to inflict pain and suffering beyond what is necessary for effective diagnosis, treatment and research. Next, there is the duty to do all that can be done to relieve all the pain and suffering which can be alleviated. I develop in some detail that individuality of pain sensitivity must be taken into account in fulfilling these obligations. I explore the issue of the relevance of informed consent and the right to refuse treatment to the matter of pain relief. And I raise the question of what conditions, if any, should override the right to refuse treatment where pain relief is of paramount concern.

    importante en los últimos años. En este estudio, objetivamos evaluar críticamente las informaciones disponibles en la literatura a respecto del uso de opioides para tratamiento del dolor crónico no oncológico y el papel de la metadona como opción terapéutica. CONTENIDO: Los estudios disponibles aun son limitados, más demuestran que determinadas subpoblaciones de pacientes portadores de dolor crónico, pueden alcanzar analgesia importante, con poca tolerancia y bajo potencial para adición, principalmente aquellos refractarios a los esquemas terapéuticos convencionales. Morfina es el opioide patrón, también otras alternativas pueden ser utilizadas como oxicodona, hidromorfona o fentanil. Metadona es un opioide sintético, inicialmente utilizado para prevenir síndrome de abstinencia en paciente dependientes, que también constituye una opción importante en el tratamiento del dolor crónico no oncológico, principalmente dolor neuropático. CONCLUSIONES: A pesar del creciente conocimiento sobre el uso de opioides en el dolor crónico no oncológico, nuevos estudios mejor controlados aun son necesarios para una discusión más científica a respecto del asunto. La metadona administrada por vía oral presenta una buena relación costeo-beneficio, representando una alternativa efectiva para mejor control del dolor en algunos pacientes.BACKGROUND AND OBJECTIVES: The use of opioids for cancer pain has already well established by several well-controlled clinical trials. However, there is a major controversy about long-term use of opioids in non-malignant chronic pain, which has been significantly intensified in the last few years. This study aimed at evaluating available data on the use of opioids for treating non-malignant chronic pain and the role of methadone as a therapeutic alternative. CONTENTS: There are few available studies, but they show that some subpopulations of chronic pain patients may achieve sustained analgesia with minor tolerance and low addiction

Therefore, an investigation was conducted into the perception of stress and coping strategies of 31 professionals of different categories from a severe burns care center (acute pain and a pain control and palliative care unit (chronic pain. For this, a sociodemographic questionnaire, the Job Stress Scale (short version and the Coping Strategies Inventory were applied. Compared to other categories, the nursing technicians indicated more stress factors. In compensation, they reported a greater diversity of coping strategies with significant differences between the services. These results corroborate previous studies, which warn of the adverse conditions that interfere in nursing practice. However, they also reveal the availability of protective factors, indicating perspectives of preventive intervention for the nursing team.La literatura especializada destaca que el manejo clínico del dolor produce dificultades psicológicas asociadas a las actividades realizadas para aliviar el sufrimiento de los pacientes.

It is important that there is a proportionate increase in the availability of acute pain-management services to match the rapid rise of clinical patient load with pain issues in the ambulatory surgery setting. Focus on ambulatory pain control with its special challenges is vital to achieve optimum pain control and prevent morbidity and mortality. Management of perioperative pain in the ambulatory surgery setting is becoming increasingly complex, and requires the employment of a multimodal approach and interventions facilitated by ambulatory surgery pain specialists, which is a new concept. A focused ambulatory pain specialist on site at each ambulatory surgery center, in addition to providing safe anesthesia, could intervene early once problematic pain issues are recognized, thus preventing emergency room visits, as well as readmissions for uncontrolled pain. This paper reviews methods of acute-pain management in the ambulatory setting with risk stratification, the utilization of multimodal interventions, including pharmacological and nonpharmacological options, opioids, nonopioids, and various routes with the goal of preventing delayed discharge and unexpected hospital admissions after ambulatory surgery. Continued research and investigation in the area of pain management with outcome studies in acute surgically inflicted pain in patients with underlying chronic pain treated with

    Full Text Available The distribution of Concholepas concholepas (Mollusca, Gastropoda, Muricidae is limited to the coasts of Chile and southern Peru. Almost all studies of this gastropod have been carried out in open coastal systems, rather than the fjords and channels of southern Chile, despite the fact that this area represents ca. 95 % of the total coastline in this country. Although there is a large volume of background literature on C. concholepas, almost nothing is published about early larval development under natural conditions, mostly because early veligers have rarely been found in nature. This study is the first attempt to determine the spatial and temporal abundance and size patterns of C. concholepas larvae in their natural environment throughout all of their developmental stages until they settle. Weekly plankton samples were obtained at the surface and at 8 m depth in four locations in southern Chile in combination with temperature and salinity records in each location. Settlement was quantified using artificial substrates in all locations. We have observed that C. concholepas larval development occurs throughout the entire year in Chilean inland seas, with early veliger larvae being released mostly from August to March, reaching the competent stage around June to August, and settling between July and August. Thus, larvae appear to have a long planktonic development that can last between 6 and 12 months. Differences in local hydrology could affect larval development of C. concholepas in this region. Further oceanographic and ecological investigation is necessary in order to answer the questions and hypotheses originated from this studyConcholepas concholepas (Mollusca, Gastropoda, Muricidae se distribuye entre las costas del sur de Perú y extremo sur de Chile.

    Full Text Available This study extends prior research on vicarious traumatization and emotion management by exploring a deeper, more life-altering effect of working with traumatized clients—namely, “soul pain.” Analyses of in-depth interviews with 29 advocates working with survivors of physical and sexual violence reveal that, as a direct consequence of hearing countless stories of human brutality, some staff members experience a profound wounding of their spirit. This finding expands our understanding of the occupational hazards of the helping professions by revealing another dimension of advocates’ lives—that of the soul or spirit—that may be affected by their work with trauma survivors.

    Full Text Available Huequi, a little-known volcano in the southern part of the Andean southern volcanic zone (SSVZ, shows a regionally unusual eruption style, mineralogy and geochemistry. The volcano comprises multiple highly-eroded lava domes. Past eruptions were accompanied by relatively minor explosive activity, most recently from 1890-1920. The rocks erupted by Huequi range from basaltic andesite to dacite, and are highly distinctive when compared to other volcanoes of the SSVZ, being K-poor and Al-rich, and containing euhedral hornblende phenocrysts. Overall compositions suggest a notably water-rich magma source, evolving through high levels of fractionation and subsequent degassing to produce highly porphyritic dome-forming andesites. The ultimate causes of water-rich magmas at this point in the arc remain unclear.El volcán Huequi es poco conocido, que se ubica en la provincia sur de la zona Volcánica Sur de los Andes (ZVSS. Sus tipos de erupción y características mineralógicas y geoquímicas son poco comunes a nivel regional. El volcán presenta múltiples domos poco erosionados. Las erupciones estuvieron acompañadas por una actividad explosiva secundaria, siendo las más recientes las ocurridas entre los años 1890 y 1920. Los magmas del Huequi son de composición andesítico-basáltica a dacítica. Si se las compara con rocas eruptadas por otros centros volcánicos de la ZVSS de los Andes, las del Huequi se caracterizan por ser pobres en K, ricas en Al y por presentar fenocristales euhedrales de anfíbola. Las composiciones totales sugieren una fuente magmática rica en H2O, que se desarrolla a través de niveles de cristalización fraccionada y desgasificación subsecuente, que producen domos volcánicos andesíticos altamente porfíricos. Sin embargo, la causa última que genera magmas ricos en H2O, en esta parte de los Andes, sigue aún sin explicación.

    Pain has been considered as part of a defensive strategy whose specific role is to signal an immediate active danger to the organism. This definition fits well for acute pain. It does not work well, however, for chronic pain that is maintained even in absence of an ongoing, active threat. Currently, acute and chronic pain are considered to be separate conditions. What follows is a review of the different theories about pain and its history. Different hypotheses regarding pain mechanisms are illustrated. New data emerging from scientific research on chronic pain (migraine in particular) involving innovative imaging techniques are reported and discussed. © 2012 American Headache Society.

    Mechanisms of inflammatory and neuropathic pains have been elucidated and translated to patient care by the use of animal models of these pain states. Cancer pain has lagged behind since early animal models of cancer-induced bone pain were based on the systemic injection of carcinoma cells....... This precluded systematic investigation of specific neuronal and pharmacological alterations that occur in cancer-induced bone pain. In 1999, Schwei et al. described a murine model of cancer-induced bone pain that paralleled the clinical condition in terms of pain development and bone destruction, confined...... to the mouse femur. This model prompted related approaches and we can now state that cancer pain may include elements of inflammatory and neuropathic pains but also unique changes in sensory processing.

    Full Text Available La energía potencial del agua presenta diferencias de un punto del suelo a otro; esas diferencias son las que originan el movimiento del agua de acuerdo a la tendencia universal de la materia en el sentido de moverse de donde la energía potencial es mayor a donde dicha energía es menor. En el suelo el agua en consecuencia se mueve hacia donde su energía decrece hasta lograr su estado de equilibrio. Se desprende entonces que la cantidad de energía potencial absoluta contenida en el agua, no es importante por sí misma, sino por su relación con la energía en diferentes lugares dentro del suelo. El concepto Potencial de agua del suelo es un criterio para esta energía.

Este resultado siembra dudas acerca de la validez general que pueden tener los patrones infracomunitarios registrados en la literatura ya que están casi exclusivamente calculados con el número de parásitos por individuo hospedador, lo que dificulta aún más la comunicación con los ecólogos, que usan la densidad u otras medidas de abundancia ecológica

    2017-01-01

    Pain is a common problem among cancer survivors, especially in the first few years after treatment. In the longer term, approximately 5% to 10% of survivors have chronic severe pain. Overall prevalence of all types pain is about 40% in some cancer survivors with previous specific diagnosis. Until recently, impact of pain in cancer survivors have largely been unexamined. This complication can be predicted by type of malignancy, its therapy, time elapsed from completion of anticancer treatment and effectivity of previous pain interventions. As the purpose of this article is to update readers on more recent data about prevalence of pain in cancer survivors and common treatment-related chronic pain etiologies in patients with a history of cancer who are beyond the acute diagnosis and treatment phase, previously known information about acute pain, pain in terminally ill patients. Some new studies in certain subpopulations of cancer survivors will be explored in more detail. (author)

Los ejemplares corresponden a las especies: Rachycentrum canadum, Elops saurus y Caulolatilus chrysops. Estos registros amplían significativamente el límite austral de su distribución. La presencia ocasional de estas especies está asociada al transporte de agua subtropical cálida proveniente de la plataforma continental brasilera. Esta hipótesis es probada mediante el análisis de imágenes satelitales de temperatura superficial del mar.We document the southern records of three species of tropical bony fishes along the coast of Buenos Aires Province, Argentina (CBAP, 36-38°S. Rachycentrum canadum, Elops saurus and Caulolatilus chrysops were caught by bottom-trawl commercial vessels. Records presented here significantly extend southward their latitudinal distribution from those previously reported. Using sea surface temperature satellite images we show a southward warm circulation event from Brazil as a putative factor to explain the occurrence of these bony fishes in the CBAP.

    Full Text Available The Centro Ecológico de Sonora is a natural protected area where the natural vegetation remained undisturbed at least until 1997. Since then, Cenchrus ciliaris has become a prominent element of the vegetation because of disturbance. Climate, soil properties, population structure and biological activity for C. ciliaris were studied to gain understanding of the ecological mechanisms that favored the invasion by this exotic grass. Mean air temperature and annual rainfall were 24.8°C and 302 mm. The soil was a loamy-sand that was poor in most nutrients, but particularly rich in phosphorus. Pennisetum ciliare was the most abundant species at the Centro Ecológico, representing over one third of total plant ground cover. Basal area for individual plants ranged from less than 1 cm² to almost 1 m². Living leaves per plant increased with precipitation, peaking at 199 leaves in March 2005, and no living leaves were found after 103 days without rain. The environmental conditions prevalent at Centro Ecológico are very favorable for C. ciliaris, whose establishment was apparently triggered by a major disturbance caused by the development of housing projects.El Centro Ecológico de Sonora es un área natural protegida donde la vegetación autóctona permaneció sin disturbios por lo menos hasta 1997. Desde entonces, Cenchrus ciliaris se ha convertido en un elemento prominente de la vegetación. Se estudiaron el clima, las propiedades del suelo, la estructura de la población y la actividad biológica de C. ciliaris, como una aproximación al entendimiento de los mecanismos ecológicos que favorecieron la invasión por este pasto exótico. La temperatura media del aire y la precipitación anual fueron de 24.8 °C y 302 mm. El suelo fue una arena limosa pobre en minerales, pero particularmente rica en fósforo.

    Full Text Available The royal crab Chaceon ramosae is one of the three species of deep-sea crabs currently exploited in Brazil. The royal crab fishery started in 2001 with foreign vessels that were extensively monitored by observers and tracked by satellite. A management plan implemented in 2005 was based only on biomass dynamics, as biological knowledge of the resource was limited at that date. Samples taken aboard were used to determine size at first sexual maturity for males and females by studying the use of allometric growth of chelae and abdomen in relation to carapace width (CW, the proportion of females with opened vulvae and eggs in the pleopods, and males showing copula marks on the first ambulatory legs. Morphometric maturity was attained, on average, at 12.1 cm (males and 10.7 cm (females. The CW50% was estimated to be 10.9 cm and 12.2 cm for females, respectively considering the vulva condition and eggs in the pleopods, and 13.6 cm for males. By size class, the maximum estimated proportions of ovigerous females by size class was 0.4 and of males with copula marks was 0.6, suggesting a bi-annual reproductive cycle for individuals of the species. The size composition analysis showed that irnmature individuals may comprise up to 70% of the catches. These results indicate the need to consider enhanced trap selectivity and lower mortality of ovigerous females as new and immediate goals to improve resource management.El cangrejo real Chaceon ramosae corresponde a una de las tres especies de cangrejos de profundidad que actualmente se explotan en Brasil.

A personal survey was administered to 770 consumers in the Bío-Bío and La Araucanía Regions, Chile, to determine the utility of information contained on the label and acceptance of information referred to as credence attributes, as well as to distinguish different consumer segments. The packaging and expiry dates were the most useful aspects of the current information. The greatest degree of agreement with respect to information that should be included was a quality seal, type of animal, handling regarding animal welfare, production system and feeding. Using cluster analysis, three segments were distinguished. The largest (49.2% agreed most strongly with including information about feeding, transport conditions, slaughtering, traceability, and production system. The second group (34.4% was indifferent to information about transport, slaughter and traceability. The smallest segment (16.4% disagreed with including information on slaughtering. Therefore, the information currently present on meat labels was useful for consumers, who would also value having information on the credence attributes associated with cattle production, such as production system, feeding and animal welfare.Considerando la importancia que han adquirido los atributos de credibilidad (sistema de producción, bienestar animal, trazabilidad, entre otros en el consumo de carne de los países desarrollados, aspectos que deben ser informados mediante el etiquetado, se realizó una encuesta personal a 770 consumidores de las Regiones del Bío-Bío y La Araucanía de Chile, para determinar la utilidad de la información contenida en el etiquetado, la aceptación de información referida a atributos de credibilidad, y distinguir diferentes segmentos de consumidores.

    Full Text Available En este trabajo se analiza el ciclo de vida de una baja segregada que afectó el sur de Sudamérica entre el 26 de Marzo y el 2 de Abril del 2007 y se explora la relación existente entre las diferentes etapas de este sistema y la precipitación ocurrida sobre la franja central de Argentina. Además se evalúa si otros procesos coadyuvaron para la ocurrencia de la misma. Las características más relevantes de este sistema son su larga duración y el lento desplazamiento, ya que entre el inicio y el fin de su vida se desplaza sólo 780 km, manteniéndose estacionario, durante las etapas de segregación y madurez, por más de 56 hs frente a la costa central chilena. Esta última característica favorece la formación de un sistema de baja presión sobre el noroeste de Argentina y la persistencia de una corriente en chorro en capas bajas del norte que se extiende desde el centro de Bolivia hasta norte argentino. La masa de aire con características tropicales conducida por esta configuración y la convergencia en niveles bajos favorecieron el desarrollo convectivo. La precipitación acumulada durante estas etapas, en algunas regiones del sur del litoral argentino, superó los 300 mm, produciendo extensas inundaciones en la región. Durante la etapa de decaimiento (96 hs de duración, el sistema se debilita a medida que se desplaza hacia el este y las precipitaciones afectaron las provincias del centro-oeste de Argentina donde la lluvia en 48 horas duplicó el promedio mensual de marzo.This paper describes the life cycle of a high level cut-off cyclonic vortex that affected southern South America between 26 March and 2 April 2007, and explores the relationship between the evolution stages of the system and the rainfall over central Argentina.

    Full Text Available OBJECTIVE: the aim was to evaluate the association between the intensity of musculoskeletal pain and reduction in work ability among nursing workers. METHOD: a cross-sectional study, involving 592 nursing staff in a public university hospital in Rio Grande do Sul, Brazil. The Brazilian version of the Finnish questionnaire for calculating Work Ability Index was used, whose score varies from 7 to 49 points. The score was dichotomized as reduced work ability (7 to 36 points and good/excellent ability (37 to 49 points. The intensity of musculoskeletal pain over the previous week was evaluated, using a numerical pain scale. RESULT: 43.3% of the participants had reduced work ability and 48.8% reported strong to unbearable pain. Even after adjusting for potentially confounding factors (function and length of service in the function, the workers who mentioned strong to unbearable pain were four times more likely to be classified in the group with reduced work ability. CONCLUSION: A positive association was determined between intensity of musculoskeletal pain and reduction in work ability. It is necessary to adopt intervention measures in the organizational structure, so as to promote/restore work ability.OBJETIVO: se objetivó evaluar la asociación entre intensidad del dolor musculo-esquelético y reducción de la capacidad para el trabajo en trabajadores de enfermería.

MATERIAL Y MÉTODOS: Durante mayo y junio de 1995, en un estudio transversal, se aplicó un cuestionario a ambos jefes de familia de una muestra de hogares de ocho localidades rurales del estado de Chiapas, México, para investigar la estructura familiar, el conocimiento acerca de la transmisión del paludismo, actividades de prevención y actitudes para la búsqueda de tratamiento. El análisis estadístico consistió en la estimación de razones de momios con intervalos de confianza y valores p usando métodos de regresión logística bivariada y multivariada. RESULTADOS: El conocimiento sobre el paludismo fue pobre y sólo 48% lo asociaron con picaduras de mosquitos. Los beneficios percibidos del rociado intradomiciliar de insecticidas se asociaron con la reducción de mosquitos, cucarachas y ratas, pero sólo 3% asoció el rociado con la prevención de la malaria. La mayoría (97.6% estuvo de acuerdo con el rociado intradomiciliar con insecticida. Noventa y nueve por ciento poseían mosquiteros y 75.7% los usaban todo el año. Otras medidas empleadas para prevenir las picaduras de mosquitos fueron el humo y espirales antimosquito. Por arriba de 40% indicó que se automedicaba en caso de fiebre en algún miembro de la familia, 38% acudía al centro de salud oficial y11% visitaba a un médico privado. Cerca de 61% usaba pesticidas agrícolas y 55% lo aplicaban ellos mismos. Las mujeres tuvieron mayor participación como promotoras de la salud y cerca de 70% de las amas de casa estaban a cargo de la implantación de medidas preventivas. CONCLUSIONES: Con el propósito de incrementar el conocimiento sobre la participación de los mosquitos en la transmisión del paludismo programas educacionales podrían ayudar a la inducción de la participación de la comunidad en las actividades para su control en la región.

    Full Text Available Associations of pteropod, cladoceran, and chaetognath species were analyzed for the southern coast of Brazil in order to present a biological diagnosis of the oceanographic conditions in winter and summer. The density data from the different species were analyzed using nodal and ordination cluster techniques, linking the species associations with salinity and temperature and, consequently, with the water masses occurring in each period. Sagitta tennis and Pleopsis polyphemoides were found to characterize the coastal water and, when associated with Evadne nordmanni and Pleopsis schmackeri, differentiated between the thermal characteristics of winter and summer, respectively. The Sub-Antarctic Shelf Water was characterized by the association of Sagitta tasmanica and Limacina retroversa in winter. The Tropical Water of the Brazil current presented several different associations, with Penilia avirostris, Sagitta enflata, and Creseis virgula dominating the shelf Tropical Water and Sagitta serratodentata, Limacina trochiformis, and Evadne spinifera characterizing the oceanic Tropical Water. The Sub-tropical Water, typical of upwelling processes, was characterized by the association of the chaetognaths Sagitta decipiens and Krohnitta subtilis, both in winter and summer. The species associations defined in this study agree with others carried out in neighboring areas and in previous sampling periods, characterizing the región as the southern transition zone.Se analizó las asociaciones de especies de Pteropoda, Cladocera y Chaetognatha en la costa sur de Brasil, para presentar un diagnóstico biológico de las condiciones oceanógraficas de invierno y verano.

    Loin pain hematuria syndrome is a rare disease with a prevalence of ∼0.012%. The most prominent clinical features include periods of severe intermittent or persistent unilateral or bilateral loin pain accompanied by either microscopic or gross hematuria. Patients with loin pain hematuria syndrome initially present with hematuria, flank pain, or most often both hematuria and flank pain. Kidney biopsies from patients with loin pain hematuria typically reveal only minor pathologic abnormalities. Further, loin pain hematuria syndrome is not associated with loss of kidney function or urinary tract infections. Loin pain hematuria syndrome-associated hematuria and pain are postulated to be linked to vascular disease of the kidney, coagulopathy, renal vasospasm with microinfarction, hypersensitivity, complement activation on arterioles, venocalyceal fistula, abnormal ureteral peristalsis, and intratubular deposition of calcium or uric acid microcrystals. Many patients with loin pain hematuria syndrome also meet criteria for a somatoform disorder, and analgesic medications, including narcotics, commonly are used to treat loin pain hematuria syndrome-associated pain. Interventional treatments include renal denervation, kidney autotransplantation, and nephrectomy; however, these methods should be used only as a last resort when less invasive measures have been tried unsuccessfully. In this review article, we discuss and critique current clinical practices related to loin pain hematuria syndrome pathophysiology, diagnosis, treatment, and prognosis.

    Full Text Available Desde el punto de vista farmacológico, es importante comprender qué es el alcohol y cómo actúa en el organismo. No existe una causa simple, sino una interacción complicada de factores neuroquímicos, fisiológicos, psicológicos y sociales que originan y desarrollan esta grave enfermedad fármaco-dependiente. La acción psicofisiológica y farmacodinámica del alcohol es fundamentalmente depresiva, por la reducción de la transmisión sináptica en el sistema nervioso humano. Es un hecho conocido que el consumo excesivo de alcohol causa una disfunción aguda y crónica del cerebro, produciendo trastornos en el sistema nervioso central, presentando alteraciones en la memoria y en las funciones intelectuales como cálculo, comprensión y aprendizaje. A nivel hepático tiene lugar, en su mayoría, el metabolismo del alcohol, produciéndose un hígado graso alcohólico, aumentando el tamaño, terminando en necrosis e inflamación grave del hígado; esto se llama hepatitis alcohólica, y si se sigue consumiendo alcohol se desarrollará la cirrosis. El alcohol también ha estado relacionado con alteraciones del miocardio; se ha constatado en animales de experimentación sanos que tanto la velocidad de contracción del músculo cardiaco y su máxima tensión disminuyen en presencia del alcohol, como consecuencia, la fuerza de cada contracción y el aumento de presión en el ventrículo izquierdo son menores, perdiendo eficacia el corazón como bomba.

  4. Pain in Down's Syndrome

    2006-01-01

    Full Text Available Pain is a homeostatic mechanism that intervenes to protect the organism from harmful stimuli that could damage its integrity. It is made up of two components: the sensory-discriminative component, which identifies the provenance and characteristics of the type of pain; and the affective-motivational component, on which emotional reflexes, following the painful sensation, depend.There is a system for pain control at an encephalic and spinal level, principally made up of the periaqueductal grey matter, the periventricular area, the nucleus raphe magnus, and the pain-inhibition complex situated in the posterior horns of the spinal cord. Through the activation of these pain-control systems, the nervous system suppresses the afference of pain signals. Endogenous opioids represent another analgesic system.In the course of various studies on pain transmission in Down patients, the reduced tolerance of pain and the incapacity to give a qualitative and quantitative description emerged in a powerful way. All of these aspects cause difficulty in evaluating pain. This is linked to several learning difficulties. However, it cannot be excluded that in these anomalies of pain perception, both the anatomical and the neurotransmitter alteration, typical of this syndrome, may hold a certain importance.This fact may have important clinical repercussions that could affect the choice of therapeutic and rehabilitative schemes for treatment of pathologies in which pain is the dominant symptom, such as postoperative pain. It could influence research on analgesics that are more suitable for these patients, the evaluation of the depth of analgesia during surgical operation, and ultimately, absence of obvious pain manifestations. In conclusion, alterations of the central nervous system, neurotransmitters, pain transmission, and all related problems should be considered in the management of pain in patients with Down's syndrome, especially by algologists and

    Healthy children are often required to repeatedly undergo painful medical procedures (eg, immunizations). Although memory is often implicated in children's reactions to future pain, there is a dearth of research directly examining the relationship between the 2. The current study investigated the influence of children's memories for a novel pain stimulus on their subsequent pain experience. One hundred ten healthy children (60 boys) between the ages of 8 and 12 years completed a laboratory pain task and provided pain ratings. Two weeks later, children provided pain ratings based on their memories as well as their expectancies about future pain. One month following the initial laboratory visit, children again completed the pain task and provided pain ratings. Results showed that children's memory of pain intensity was a better predictor of subsequent pain reporting than their actual initial reporting of pain intensity, and mediated the relationship between initial and subsequent pain reporting. Children who had negatively estimated pain memories developed expectations of greater pain prior to a subsequent pain experience and showed greater increases in pain ratings over time than children who had accurate or positively estimated pain memories. These findings highlight the influence of pain memories on healthy children's expectations of future pain and subsequent pain experiences and extend predictive models of subsequent pain reporting.

    Full Text Available The effects of solar ultraviolet (UV radiation during daily cycles on photosynthesis and two key enzymes involved in carbon incorporation, the carbonic anhydrase, and in inorganic nitrogen reduction, the nitrate reductase, of macroalgae from southern Spain are presented. During daily cycles, photoinhibition in several intertidal macroalgae, expressed as decrease in the effective quantum yield from the morning to noon time, was linearly dependent on the daily integrated irradiance. However, recovery, expressed as the increase in the effective quantum yield from noon to the afternoon, presented a different pattern; full recovery was found below daily integrated irradiance of 1.0 x10(4 kJ m-2. However, recovery reached only 50 % at higher irradiances. The existence of daily photoinhibition and full recovery in intertidal algae suggests that photoinhibition is a photoprotective mechanism against high solar radiation as in higher plants, and that patterns of photoinhibition and recovery are affected by accumulative doses. Activities of carbonic anhidrase and nitrate reductase were determined in three marine macroalgae (Plocamium cartilagineum, Ulva rigida and Fucus spiralis under full (PAR + UV-A + UV-B and excluded UV solar radiation (PAR. Under PAR + UV-A + UV-B, peaks of enzyme activity were found in P. cartilagineum during the evening, and accordingly to data previously published for other red macroalgae. This situation was modified by the absence of UV radiation since the increase in the activities was delayed several hours. In the three macroalgae and under full solar radiation, a significant and negative correlation was found only when data from nitrate reductase activity was shifted in time during at least four hours. This correlation is lost in Ulva rigida when UV radiation is excluded. The existence of these daily variations with a negative correlation of both enzyme activities could reflect a complex regulatory link between carbon and

Samples (73 were collected from dairy farms along Southern Chile (39° to 44° S and 71 to 73° W. Analyses were carried out on laboratory conditions using conventional techniques as well as using each of the quick tests. Results were subjected to straight-line regression analyses. Agros and Quantofix N-NH4+ measurements were accurate (P 0.80. The hydrometer estimations of TN, TP, and TK were also reliable (P Actualmente en Chile se carece de herramientas para determinar en tiempo real el aporte de nutrientes de purines.

    Full Text Available This study aimed to determine the shell choice pattern of the southern Atlantic endemic hermit crab Loxopagurus loxochelis from two different biogeographic provinces in Brazil and Argentina. Size and shell species preferences were determined for the two most occupied shell types (i.e., Olivancillaria urceus and Buccinanops gradatum in Caraguatatuba region (Brazil and in Mar del Plata (Argentina. Shell occupation was analyzed considering the biometric characteristics of shells, the occurrence of shell types, and the preference of the hermit crabs for the most frequently occupied shell species. Samples were taken using otter trawl in the infralittoral area of both regions and the animals captured were measured and weighed. Shells were identified, weighed, measured and their internal volume calculated. Experiments were accomplished in aquaria where the hermit crabs were allocated together with a sufficient number of adequate sized shells. In laboratory, L. loxochelis from Argentina presented no preference for any of the two offered shell species, while the specimens from Brazil significantly preferred B. gradatum shells. It was observed that the relation between shell dimensions and shell weight were the variables that best explained the association between hermit crabs and shells. Considering that Argentinean specimens are larger than the Brazilian ones we may infer that body size is a relevant factor to explain the observed differences found in relation to shell type preferenceEste estudio tuvo por objetivo determinar la forma de elección de conchas de caracoles por el cangrejo ermitaño endémico del Atlántico sudoccidental Loxopagurus loxochelis proveniente de dos provincias biogeográficas de Brasil y Argentina.

    Full Text Available Along the Central Andes a pattern of vertical axis tectonic rotations has been paleomagnetically identified. Such rotations are counterclockwise north of Arica Deflection (~19°S and clockwise to the south. Different hypothesis and models have been proposed to explain the Central Andean Rotation Pattern (CARP. However, the CARP is a subject of ongoing debate. Recently, the quantity, quality, and geographic distribution of paleomagnetic data have expanded greatly. Such expansion has been accompanied by an increase in the knowledge of the deformation periods in the Andes, allowing a more detailed analysis of the temporal and spatial distribution of the detected rotations. We compiled and analyzed the available Cenozoic paleomagnetic data for the region extending between 19° and 27.5°S. The results suggest the possible existence of different rotational domains with distinct characteristics. We propose that in the Southern Central Andes, a close correlation would exist between the style and the temporal and spatial pattern of deformation and the amount of recorded vertical axis rotations. However, in order to further investigate such relationship, new paleomagnetic studies are necessary, particularly in the Eastern Cordillera domain, in Paleogene rocks cropping out in the Altiplano-Puna and in Neogene rocks of the forearc.En los Andes Centrales se ha identificado un patrón de rotaciones tectónicas según ejes verticales a través de estudios paleomagnéticos. Dichas rotaciones son en sentido antihorario al norte del codo de Arica (~19°S y en sentido horario hacia el sur. Distintos autores han propuesto diferentes hipótesis y modelos para tratar de explicar el Patrón de Rotaciones de los Andes Centrales (PRAC. Sin embargo, el PRAC sigue siendo objeto de debate. Recientemente, la cantidad, calidad y la distribución geográfica de los datos paleomagnéticos ha aumentado de manera notable. Dicho incremento ha sido acompañado por un importante

    Full Text Available El artículo se basa en un estudio comparativo sobre las transformaciones estructurales en la agricultura de España, Italia y Grecia desde los años 80, a partir de un análisis de investigaciones realizadas sobre el tema y de datos procedentes de los organismos nacionales de estadística y de Eurostat. En el texto se analiza el papel de la agricultura en la organización de las áreas rurales, concentrándose en sus procesos de internacionalización y en las modalidades de gobierno del trabajo vivo, que es especialmente trabajo migrante. Se muestran las transformaciones producidas por la presencia migrante en interacción con las sociedades locales, concluyendo que las poblaciones autóctonas han desarrollado una actitud funcionalista hacia los inmigrantes, favoreciendo una regulación social y política que antepone los derechos y los intereses de los locales a los de los extranjeros. Finalmente, se señala la crisis de esta forma de regulación, que se manifiesta en las relaciones conflictivas que los trabajadores inmigrantes viven con las explotaciones y las poblaciones locales en muchas áreas agrícolas. The paper is based on a comparative review of a part of social researches about the social and neoliberal transformation in the farming of Spain, Italy and Greece since the 1980s and on an analysis of statistical data. The paper analyzes the role of agriculture in the organization of the rural areas, highlighting its processes of internationalization and the management of the living labor, that mainly is migrant labor. It draws attention to transformations produced by migrant presence in interaction with the local societies, recognizing that local populations have developed a functional attitude towards immigrants, favoring a social and political regulation that put first rights and interests of native inhabitants. The paper finally signals the crisis of this way of regulation, that is manifested by the conflictual relationship between

    Full Text Available Eurymetopum is an Andean clerid genus with 22 species. We modeled the ecological niches of 19 species with Maxent and used them as potential distributional maps to identify patterns of richness and endemicity. All modeled species maps were overlapped in a single map in order to determine richness. We performed an optimality analysis with NDM/VNDM in a grid of 1º latitude-longitude in order to identify endemism. We found a highly rich area, located between 32º and 41º south latitude, where the richest pixels have 16 species. One area of endemism was identified, located in the Maule and Valdivian Forest biogeographic provinces, which extends also to the Santiago province of the Central Chilean subregion, and contains four endemic species (E. parallelum, E. prasinum, E. proteus, and E. viride, as well as 16 non-endemic species. The sympatry of these phylogenetically unrelated species might indicate ancient vicariance processes, followed by episodes of dispersal. Based on our results, we suggest a close relationship between these provinces, with the Maule representing a complex area.Eurymetopum es un género de cléridos andinos con 22 especies. Modelamos los nichos ecológicos de 19 especies con Maxent y los utilizamos como mapas de distribución potencial para identificar patrones de riqueza y endemismo.

Realizamos un análisis de optimalidad con NDM/VNDM en una cuadrícula de 1º de latitud-longitud para identificar el endemismo. Hallamos un área de mayor riqueza, localizada entre los 32º y 41º de latitud sur, donde los pixeles más ricos poseen 16 especies. Se identificó un área de endemismo en las provincias biogeográficas del Maule y el Bosque Valdiviano, la cual se extiende también a la provincia de Santiago de la subregión Chilena Central, y que contiene cuatro especies endémicas (E. parallelum, E. prasinum, E. proteus y E. viride, as

Las características morfológicas de los esporos, el lugar de desarrollo y la especie huésped involucrada sugieren que el microorganismo en cuestión, pertenece al género Nephridiophaga y sería N. apis Ivani, especie tipo cuyo conocimiento es extremadamente limitado. El hallazgo constituye el primer registro de un nefridiofágido asociado a A mellifera fuera del continente europeo.During surveys for the detection of protists associated to Apidae in the Pampas region, biconcave oval spores, and spore clumps were observed in the Malpighian tubules of honeybees from Dufaur, Saavedra county, southwestern Buenos Aires province. Mature spores measured 4.8 ± 0.05 x 2.4 ± 0.03 μm, and mean spore load was 5.71 ± 1.49 x 10(6 per honeybee. Detections were from July to October 2006, and prevalence in positive colonies ranged from 1 to 16.7%. Morphology of the spores, the site of development, and the identity of the host species suggest that the isolated microorganism belongs to the genus Nephridiophaga and would be N apis Ivani, the type species, knowledge on which is extremely limited. The finding constitutes the first record of a nephridiophagid in honeybees outside of Europe.

    2012-05-01

    Previous studies on children's pain perspectives remain limited to English-speaking populations. An exploratory cross-sectional descriptive design was used to investigate the developmental progression of children's pain perspectives, including their pain experience, its definition and attributes, causality and coping. The Children's Pain Perspectives Inventory was applied to 180 healthy Spanish children. A coding system was developed following the content analysis method. Three age groups were compared: 4-6 years, corresponding to the Piagetian pre-operational stage of cognitive development; 7-11 years, corresponding to stage of concrete operations; and 12-14 years, corresponding to the period of early formal operations. In children between 4 and 6, the predominant narratives related to physical injuries, the notion of causality and the definition of pain. In children between 7 and 11, the predominant narratives were those in which pain was described as a sensation in one part of the body. The view of pain as having an emotional basis significantly increased with age and was more frequent in adolescents. In contrast, children between 4-6 and 7-11 indicated that pain occurs spontaneously. The denial of any positive aspects of pain significantly decreased with age; some children between 7 and 11 referred to the 'possibility of relief', while the view that pain is a 'learning experience' was significantly more frequent among adolescents aged between 12 and 14 years. The use of cognitive strategies to control pain significantly increased with age. Between 12 and 14 years of age, adolescents communicate pain by non-verbal behaviour and reported that they do not express demands for relief. There was a progression from concrete to more complex notions of pain as age increased. These results may be of use to health professionals and parents to understand how children at various developmental stages express and cope with pain and to develop tools that effectively assess and

OBJECTIVE: To estimate the prevalence of hypercholesterolemia and associated factors in 07-12 year-old school children. METHODS: School based cross sectional study of a random sample of 1,294 07-12 year-old school children from Caxias do Sul/RS, Brazil. The students answered an interview with information on socioeconomic status, food habits, and physical and leisure activities. Total cholesterol, cardiorespiratory fitness, body mass and height were measured to calculate body mass index. For the data treatment, univariate, bivariate, and multivariate analyzes were used. RESULTS: The multivariate analysis identified that individuals from high socioeconomic level (OR: 1.70; CI: 1.05-2.75, of female gender (OR: 1.32; CI: 1.03-1.67, and overweight (OR: 1.40; IC: 1.10-1.77 had increased chances of having increased total cholesterol (> 3rd tercile. CONCLUSION: High total cholesterol levels on 07-12 year-old school children are associated with high socioeconomic level, female gender, and overweight

    Pain-related worry is distinct from, but related to, pain catastrophizing (PC) and anxiety. Worry and its relationship with other variables have been studied in people with chronic pain but not in people with chronic orofacial pain. The authors explored the prevalence of trait, general and pain-related worry and the association of worry with higher pain levels and other variables. The authors assessed people who had a diagnosis of chronic orofacial pain by using nonpain-related trait worry, state anxiety, trait anxiety, PC and pain measures. The participants' answers to an open-ended question about what they were most worried about led to the identification of worry domains, including worry about pain. The authors found that worrying about pain was related significantly to worst and least pain levels, pain interference and pain duration, as well as moderated trait worry in predicting pain interference. Although trait worry was not correlated directly with pain, when moderated by PC, it made substantial contributions in predicting pain interference. Participants with chronic orofacial pain reported experiencing substantial levels of trait worry, anxiety, PC and worry about pain that related to pain ratings directly and indirectly. Clinicians should assess pain-related worry in patients with chronic orofacial pain to understand the effects of worry on pain and functioning. Clinicians could treat these patients more effectively by helping them reduce their levels of pain-related worry and focusing on improved coping.

    This study investigated the relationships between the type of pain experienced (performance pain and injury pain), the cognitive appraisal of pain and pain coping styles in dancers. Fifty-one professional ballet and contemporary dancers (17 males and 34 females), with the mean age of 25.9 years, completed a general pain questionnaire, the Pain Appraisal Inventory, the Survey of Pain Attitudes Control Subscale, and the Sports Inventory for Pain. Multivariate analyses of variance indicated that both the cognitive appraisal of the pain and pain coping styles did not differ according to the type of pain experienced or the pain severity. However, it was found that dancers with performance pain of either low or high severity were more likely to dance in pain than dancers experiencing injury pain. Multiple regression analyses indicated that the appraisal of pain as threatening was predictive of the use of avoidance and catastrophizing pain coping styles. Overall, results indicated that dancers may not differentiate between performance pain and injury pain, or modify their appraisal and coping strategies according to the characteristics of the pain experienced. The study highlighted an opportunity for increased education for dancers in recognizing the difference between pain considered to be a routine aspect of training and pain which is a signal of serious injury.

    Arthritis is a chronic disease of joints. It is highly prevalent, particularly in the elderly, and is commonly associated with pain that interferes with quality of life. Because of its chronic nature, pharmacological approaches to pain relief and joint repair must be safe for long term use, a quality many current therapies lack. Nutraceuticals refer to compounds or materials that can function as nutrition and exert a potential therapeutic effect, including the relief of pain, such as pain related to arthritis, of which osteoarthritis (OA) is the most common form. Of interest, nutraceuticals have recently been shown to have potential in relieving OA pain in human clinical trials. Emerging evidence indicates nutraceuticals may represent promising alternatives for the relief of OA pain. In this paper, we will overview OA pain and the use of nutraceuticals in OA pain management, focusing on those that have been evaluated by clinical trials. Furthermore, we discuss the biologic and pharmacologic actions underlying the nutraceutical effects on pain relief based on the potential active ingredients identified from traditional nutraceuticals in OA pain management and their potential for drug development. The review concludes by sharing our viewpoints that future studies should prioritize elucidating the mechanisms of action of nutraceuticals in OA and developing nutraceuticals that not only relieve OA pain, but also mitigate OA pathology.

    Full Text Available Background Phantom limb pain is a common problem after limb amputation (41-85%. It is described as an extremely painful sensation in the missing part of the body that can last for hours, days or even years. It is considered to arise from cortical reorganization, although many factors can increase the risk of phantom limb pain: pain before surgery, age and sex of the patients, the time elapsed since surgery, stump pain, inadequate prosthesis. Phantom limb pain therapy is very complicated. Case report We reported a case of 80-year-old patient suffering from phantom limb pain and phantom sensation 25 years after the amputation of his left leg due to the injury. The patient has pain at the site of amputation, sensation that he has the leg and that it occupies an unusual position and almost daily exhausting phantom limb pain (6-9 visual analogue scale - VAS with disturbed sleep and mood. We managed to reduce the pain under 4 VAS and decrease the patient suffering by combining drugs from the group of coanalgetics (antidepressants, antiepileptics, non-pharmacological methods (transcutaneous electroneurostimulation - TENS, mirror therapy and femoral nerve block in the place of disarticulation of the left thigh. Conclusion Phantom limb pain therapy is multimodal, exhausting for both the patient and the physician and it is often unsuccessful. The combination of different pharmacological and non-pharmacological modalities can give satisfactory therapeutic response.

    The efficacy of the N-methyl-D-aspartate receptor antagonist ketamine as an analgesic agent is still under debate, especially for indications such as chronic pain. To understand the efficacy of ketamine for relief of pain, we performed a literature search for relevant narrative and systematic reviews and meta-analyses. We retrieved 189 unique articles, of which 29 were deemed appropriate for use in this review. Ketamine treatment is most effective for relief of postoperative pain, causing reduced opioid consumption. In contrast, for most other indications (that is, acute pain in the emergency department, prevention of persistent postoperative pain, cancer pain, and chronic non-cancer pain), the efficacy of ketamine is limited. Ketamine’s lack of analgesic effect was associated with an increase in side effects, including schizotypical effects. PMID:28979762

    Labour is an emotional experience and involves both physiological and psychological mechanisms. The pain of labour is severe but despite this its memory diminishes with time. Labour pain has two components: visceral pain which occurs during the early first stage and the second stage of childbirth, and somatic pain which occurs during the late first stage and the second stage. The pain of labour in the first stage is mediated by T10 to L1 spinal segments, whereas that in the second stage is carried by T12 to L1, and S2 to S4 spinal segments. Pain relief in labour is complex and often challenging without regional analgesia. Effective management of labour pain plays a relatively minor role in a woman's satisfaction with childbirth.

    Pain has always been considered as part of a defensive strategy, whose specific role is to signal an immediate, active danger. This definition partially fits acute pain, but certainly not chronic pain, that is maintained also in the absence of an active noxa or danger and that nowadays is considered a disease by itself. Moreover, acute pain is not only an automatic alerting system, but its severity and characteristics can change depending on the surrounding environment. The affective, emotional components of pain have been and are the object of extensive attention and research by psychologists, philosophers, physiologists and also pharmacologists. Pain itself can be considered to share the same genesis as emotions and as a specific emotion in contributing to the maintenance of the homeostasis of each unique subject. Interestingly, this role of pain reaches its maximal development in the human; some even argue that it is specific for the human primate.

    Full Text Available Contrary to popular knowledge, back pain is quite frequently seen in children. While very rare in the pre-school age group, frequency reaches 30% in the adolescent period. In many cases, the causes of back pain in childhood cannot be exactly determined and the pain disappears by itself in a short time. It should be remembered that back pain that persists for more than two weeks may be associated with organic causes. Whether or not there have been disruptions in neurological functions should be definitely probed in the medical history. Keeping in mind that back pain could be a part of a systemic disease, a systemic examination should be carried out in cases where there has been long-term back pain. The complaint of childhood back pain should be assessed with a thorough history, a careful physical examination and advanced testing tools. [TAF Prev Med Bull 2011; 10(1.000: 115-118

    Full Text Available Ibn Sina (Latin name – Avicenna, 980–1037 is a famous Muslim physician who wrote The Canon of Medicine. Pain-related writings within The Canon were identified and analysed and compared to Galen and Modern Pain Theory. We found evidence in The Canon that Avicenna challenged Galen's concept of pain. Galen insisted that injuries (breach of continuity were the only cause of pain. In contrast, Avicenna suggested that the true cause of pain was a change of the physical condition (temperament change of the organ whether there was an injury present or not. Avicenna extended Galen's descriptions of 4 to 15 types of pain and used a terminology that is remarkably similar to that used in the McGill Pain Questionnaire.

    Full Text Available Chronic pelvic pain (CPP is defined as nonmalignant pain perceived in the structures related to the pelvis that has been present for more than 6 months or a non acute pain mechanism of shorter duration. Pain in the pelvic region can arise from musculoskeletal, gynaecological, urologic, gastrointestinal and or neurologic conditions. Key gynaecological conditions that contribute to CPP include pelvic inflammatory disease (PID, endometriosis, adnexa pathologies (ovarian cysts, ovarian remnant syndrome, uterine pathologies (leiomyoma, adenomyosis and pelvic girdle pain associated with pregnancy. Several major and minor sexually transmitted diseases (STD can cause pelvic and vulvar pain. A common painful condition of the urinary system is Interstitial cystitis(IC. A second urologic condition that can lead to development of CPP is urethral syndrome. Irritable bowel syndrome (IBS is associated with dysmenorrhoea in 60% of cases. Other bowel conditions contributing to pelvic pain include diverticular disease,Crohn′s disease ulcerative colitis and chronic appendicitis. Musculoskeletal pathologies that can cause pelvic pain include sacroiliac joint (SIJ dysfunction, symphysis pubis and sacro-coccygeal joint dysfunction, coccyx injury or malposition and neuropathic structures in the lower thoracic, lumbar and sacral plexus. Prolonged pelvic girdle pain, lasting more than 6 months postpartum is estimated in 3% to 30% of women. Nerve irritation or entrapment as a cause of pelvic pain can be related to injury of the upper lumbar segments giving rise to irritation of the sensory nerves to the ventral trunk or from direct trauma from abdominal incisions or retractors used during abdominal surgical procedures. Afflictions of the iliohypogastric, ilioinguinal, genitofemoral, pudendal and obturator nerves are of greatest concern in patients with pelvic pain. Patient education about the disease and treatment involved is paramount. A knowledge of the differential

    In patients with back pain there is only a poor correlation between clinical and radiological symptoms. Therefore the interpretation of radiological findings is only possible with respect to the natural history of the disease. Indication for radiological examination is given for early diagnosis and treatment of malinformation of the spine; diagnosis and treatment of functional disturbances of the spine with back- and low back pain and diagnosis and treatment of diseases which affect the stability of the vertebrae.

    A significant proportion of children with functional abdominal pain develop chronic pain. Identifying clinical characteristics predicting pain persistence is important in targeting interventions. We examined whether child anxiety and/or pain-stooling relations were related to maintenance of abdominal pain frequency and compared the predictive value of 3 methods for assessing pain-stooling relations (ie, diary, parent report, child report). Seventy-six children (7-10 years old at baseline) who presented for medical treatment of functional abdominal pain were followed up 18 to 24 months later. Baseline anxiety and abdominal pain-stooling relations based on pain and stooling diaries and child- and parent questionnaires were examined in relationship to the persistence of abdominal pain frequency. Children's baseline anxiety was not related to persistence of pain frequency. Children who, however, displayed irritable bowel syndrome (IBS) symptoms at baseline maintained pain frequency at follow-up, whereas in children in whom there was no relationship between pain and stooling, pain frequency decreased. Pain and stool diaries and parent report of pain-stooling relations were predictive of pain persistence but child-report questionnaires were not. The presence of IBS symptoms in school-age children with functional abdominal pain appears to predict persistence of abdominal pain over time, whereas anxiety does not. Prospective pain and stooling diaries and parent report of IBS symptoms were predictors of pain maintenance, but child report of symptoms was not.

    Full Text Available Abstract Introduction On 6 April 2009, at 03:32 local time, an Mw 6.3 earthquake hit the Abruzzi region of central Italy causing widespread damage in the City of L Aquila and its nearby villages. The earthquake caused 308 casualties and over 1,500 injuries, displaced more than 25,000 people and induced significant damage to more than 10,000 buildings in the L'Aquila region. Objectives This observational retrospective study evaluated the prevalence and drug treatment of pain in the five weeks following the L'Aquila earthquake (April 6, 2009. Methods 958 triage documents were analysed for patients pain severity, pain type, and treatment efficacy. Results A third of pain patients reported pain with a prevalence of 34.6%. More than half of pain patients reported severe pain (58.8%. Analgesic agents were limited to available drugs: anti-inflammatory agents, paracetamol, and weak opioids. Reduction in verbal numerical pain scores within the first 24 hours after treatment was achieved with the medications at hand. Pain prevalence and characterization exhibited a biphasic pattern with acute pain syndromes owing to trauma occurring in the first 15 days after the earthquake; traumatic pain then decreased and re-surged at around week five, owing to rebuilding efforts. In the second through fourth week, reports of pain occurred mainly owing to relapses of chronic conditions. Conclusions This study indicates that pain is prevalent during natural disasters, may exhibit a discernible pattern over the weeks following the event, and current drug treatments in this region may be adequate for emergency situations.

  14. Chronic Abdominal Wall Pain.

    Chronic abdominal wall pain is a poorly recognized clinical problem despite being an important element in the differential diagnosis of abdominal pain. This review is based on pertinent articles that were retrieved by a selective search in PubMed and EMBASE employing the terms "abdominal wall pain" and "cutaneous nerve entrapment syndrome," as well as on the authors' clinical experience. In 2% to 3% of patients with chronic abdominal pain, the pain arises from the abdominal wall; in patients with previously diagnosed chronic abdominal pain who have no demonstrable pathological abnormality, this likelihood can rise as high as 30% . There have only been a small number of clinical trials of treatment for this condition. The diagnosis is made on clinical grounds, with the aid of Carnett's test. The characteristic clinical feature is strictly localized pain in the anterior abdominal wall, which is often mischaracterized as a "functional" complaint. In one study, injection of local anesthesia combined with steroids into the painful area was found to relieve pain for 4 weeks in 95% of patients. The injection of lidocaine alone brought about improvement in 83-91% of patients. Long-term pain relief ensued after a single lidocaine injection in 20-30% of patients, after repeated injections in 40-50% , and after combined lidocaine and steroid injections in up to 80% . Pain that persists despite these treatments can be treated with surgery (neurectomy). Chronic abdominal wall pain is easily diagnosed on physical examination and can often be rapidly treated. Any physician treating patients with abdominal pain should be aware of this condition. Further comparative treatment trials will be needed before a validated treatment algorithm can be established.

    Brunjes, George B

    2010-01-01

    Spiritual pain/suffering is commonly experienced by persons with life-limiting illness and their families. Physical pain itself can be exacerbated by non-physical causes such as fear, anxiety, grief, unresolved guilt, depression and unmet spiritual meets. Likewise, the inability to manage physical pain well can be due to emotional and spiritual needs. This is why a holistic, interdisciplinary assessment of pain and suffering is required for each patient and family. The mind, body and spirit are understood in relationship to each other and, in those cases, in relationship to a deity or deities are important to understand. Cultural interpretations of pain and suffering may conflict with the goals of palliative care. Understanding the spiritual framework of the patient and family can help to assure that the physical and spiritual suffering of the patient can be eliminated to provide a peaceful death. Spiritual practices may help in the management of physical pain.

  18. [Cannabinoids in pain medicine].

    The endocannabinoid system (ECS) controls a large number of vital functions. Suboptimal tone of the ECS in certain regions of the nervous system may be associated with disorders that are also associated with pain. Pain and inflammation processes can be modulated by the exogenous supply of cannabinoids. Low-to-moderate pain-relieving effects and in individual cases large pain-relieving effects were observed in randomized, controlled studies of various types of chronic pain. People with chronic neuropathic pain and stress symptoms seem to particularly benefit. The therapeutic range of cannabinoids is small; often small doses are sufficient for clinically significant effects. The "Cannabis-als-Medizin-Gesetz" (cannabis as medicine law) allows the prescription of cannabis preparations under certain conditions. Available data indicate good long-term efficacy and tolerability. However, there is little systematic long-term experience from clinical studies.

    Full Text Available Background. Chronic unexplained orofacial pain is frequently the cause of prolonged suffering for the patient and an unsolvable problem for the therapist. Pathophysiology of the onset of this type of pain is virtually unknown. Still, it is possible to divide chronic orofacial pain into several separate categories, according to its onset, symptoms and therapy. All forms of this type of pain have a strong psychological component.Methods. A retrograde review was conducted, in which patients’ records, treated in 1994 for chronic unexplained orofacial pain, were followed through a 5 year period. The modalities of treatment then and at present were compared.Conclusions. Except for trigeminal neuralgia, where carbamazepine remains the first choice drug, treatment of chronic facial pain has changed considerably.

    Full Text Available Thoracic spine pain, or thoracalgia, is one of the common reasons for seeking for medical advice. The epidemiology and semiotics of pain in the thoracic spine unlike in those in the cervical and lumbar spine have not been inadequately studied. The causes of thoracic spine pain are varied: diseases of the cardiovascular, gastrointestinal, pulmonary, and renal systems, injuries to the musculoskeletal structures of the cervical and thoracic portions, which require a thorough differential diagnosis. Facet, costotransverse, and costovertebral joint injuries and myofascial syndrome are the most common causes of musculoskeletal (nonspecific pain in the thoracic spine. True radicular pain is rarely encountered. Traditionally, treatment for thoracalgia includes a combination of non-drug and drug therapies. The cyclooxygenase 2 inhibitor meloxicam (movalis may be the drug of choice in the treatment of musculoskeletal pain.

    Full Text Available The past 2-3 decades have seen dramatic changes in the approach to pain management in the neonate. These practices started with refuting previously held misconceptions regarding nociception in preterm infants. Although neonates were initially thought to have limited response to painful stimuli, it was demonstrated that the developmental immaturity of the central nervous system makes the neonate more likely to feel pain. It was further demonstrated that untreated pain can have long-lasting physiologic and neurodevelopmental consequences. These concerns have resulted in a significant emphasis on improving and optimizing the techniques of analgesia for neonates and infants. The following article will review techniques for pain assessment, prevention, and treatment in this population with a specific focus on acute pain related to medical and surgical conditions.

    Full Text Available The Ramlat as-Sab'atayn desert margin near Ma'rib, Yemen, displays well-preserved Early Holocene paleosols that are documented by micromorphological and pedological data. The buried soils, which are represented by Ahb horizons, indicate soil formation mostly before 8.3 cal ka BP. In contrast, sandy cover sediments without signs of pedogenesis appeared between 8.3 and 6.6 cal ka BP due to increasing aridity. Characteristic micromorphological features of the cover sediments are a single grain microstructure, crystallitic b-fabric, predominant occurrence of fresh sideromelane, and remnants of microlayers. Micromorphological pedogenic features in the buried Ah horizons include a subangular blocky microstructure, undifferentiated b-fabric as a result of enrichment of organic matter and decalcification, and the predominant occurrence of completely altered sideromelane. Most of these horizons appeared to be nearly completely decalcified so that in parts a stipple speckled b-fabric and neoformed clay coatings could be detected as a result of stronger weathering and soil formation. Pedogenic data provide important information about Holocene climate fluctuations, including the amount of precipitation, which was calculated on the basis of geochemical data from buried A, AB and B horizons. The buried paleosols represent moist climate conditions with precipitation ranging from 400 to 600 mm a-1.En los márgenes del desierto Ramlat as-Sab'atayn, cerca de Ma'rib (Yemen, se encuentran paleosuelos del Holoceno Inferior bien conservados que se documentan con datos micromorfológicos y edáficos.

    Although most patients recover from acute whiplash injuries, those with chronic whiplash syndrome develop signs of central nervous system (CNS) amplification of pain and have a poor prognosis. In this context, specific pain generators from acute whiplash have been identified through clinical, biomechanical, and animal studies. This article gives a clinical perspective on current understanding of these pain generators, including the phenomenon of CNS sensitization. Copyright © 2015 Elsevier Inc. All rights reserved.

    Scoliosis is defined as a lateral deviation of the spine from the normal plumb line. Commonly, there is a rotational component and deviation also in the sagittal plane (kyphosis or hyperlordosis). When scoliosis presents in adults, it is often painful. In contrast, back pain in a child is considered rare, and serious underlying pathology should be excluded, particularly since idiopathic scoliosis is typically painless. A painful scoliosis in a child or adolescent, especially if the patient has a left-sided curve, should be examined thoroughly. The aim of this review is to illustrate the causes of a painful scoliosis in children, adolescents and adults. (orig.)

  10. Acute pain assessment

    LENUS (Irish Health Repository)

    Clear, Elaine

    2016-05-01

    The International Association for the Study of Pain defines pain as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage” (IASP, 1997). This definition of pain emphasises that it is neither a sensory nor an emotional experience, but a combination of both. It is a subjective experience influenced by physical, psychological and environmental factors that is assessed from a biopsychosocial perspective. The gold standard in assessing pain however is always what the patient says it is.

    Full Text Available OBJECTIVE: To understand the social context of female sex workers who use crack and its impact on HIV/AIDS risk behaviors. METHODODOLOGICAL PROCEDURES: Qualitative study carried out in Foz do Iguaçu, Southern Brazil, in 2003. Twenty-six in-depth interviews and two focus groups were carried out with female commercial sex workers who frequently use crack. In-depth interviews with health providers, community leaders and public policy managers, as well as field observations were also conducted. Transcript data was entered into Atlas.ti software and grounded theory methodology was used to analyze the data and develop a conceptual model as a result of this study. ANALYSIS OF RESULTS: Female sex workers who use crack had low self-perceived HIV risk in spite of being engaged in risky behaviors (e.g. unprotected sex with multiple partners. Physical and sexual violence among clients, occasional and stable partners was widespread jeopardizing negotiation and consistent condom use. According to health providers, community leaders and public policy managers, several female sex workers who use crack are homeless or live in slums, and rarely have access to health services, voluntary counseling and testing, social support, pre-natal and reproductive care. CONCLUSIONS: Female sex workers who use crack experience a plethora of health and social problems, which apparently affect their risks for HIV infection. Low-threshold, user-friendly and gender-tailored interventions should be implemented, in order to increase the access to health and social-support services among this population. Those initiatives might also increase their access to reproductive health in general, and to preventive strategies focusing on HIV/AIDS and other sexually transmitted infections.OBJETIVO: Comprender el contexto social en el cual están insertadas trabajadoras del sexo que usan crack y su impacto en la adopción de comportamientos de riesgo frente al HIV/Sida.

    Up to 80% of residents in aged care facilities (ACFs) experience pain, which is often suboptimally managed. The purpose of this study was to characterize pain management in ACFs and identify the barriers to optimal pain management. This exploratory descriptive qualitative study used semistructured interviews in five Southern Tasmania, Australian ACFs. Interviewees included 23 staff members (18 nurses and 5 facility managers) and were conducted from September to November 2015. Interviews included questions about how pain was measured or assessed, what happened if pain was identified, barriers to pain management, and potential ways to overcome these barriers. Interviewees noted that there were no formal requirements regarding pain assessment at the ACFs reviewed; however, pain was often informally assessed. Staff noted the importance of adequate pain management for the residents' quality of life and employed both nonpharmacologic and pharmacologic techniques to reduce pain when identified. The barriers to optimal pain management included difficulty identifying and assessing pain, residents' resistance to reporting pain and/or taking medications, and communication barriers between the nursing staff and GPs. Staff interviewed were dedicated to managing residents' pain effectively; however, actions in a number of areas could improve resident outcomes. These include a more consistent approach to documenting pain in residents' progress notes and improving nurse-GP communications to ensure that new or escalating pain is identified and expedient changes can be made to the resident's management. Additionally, resident, family, nurse, and carer education, conducted within the facilities on a regular basis, could help improve the pain management of residents. Copyright © 2017.

  13. Doubling Your Payoff: Winning Pain Relief Engages Endogenous Pain Inhibition

    When in pain, pain relief is much sought after, particularly for individuals with chronic pain. In analogy to augmentation of the hedonic experience ("liking") of a reward by the motivation to obtain a reward ("wanting"), the seeking of pain relief in a motivated state might increase the experience of pain relief when obtained. We tested this hypothesis in a psychophysical experiment in healthy human subjects, by assessing potential pain-inhibitory effects of pain relief "won" in a wheel of fortune game compared with pain relief without winning, exploiting the fact that the mere chance of winning induces a motivated state. The results show pain-inhibitory effects of pain relief obtained by winning in behaviorally assessed pain perception and ratings of pain intensity. Further, the higher participants scored on the personality trait novelty seeking, the more pain inhibition was induced. These results provide evidence that pain relief, when obtained in a motivated state, engages endogenous pain-inhibitory systems beyond the pain reduction that underlies the relief in the first place. Consequently, such pain relief might be used to improve behavioral pain therapy, inducing a positive, perhaps self-amplifying feedback loop of reduced pain and improved functionality.

    Cancer pain is a devastating condition. Pain in the orofacial region, may be present as the single symptom of cancer or as a symptom of cancer in its later stages. This manuscript revises in a comprehensive manner the content of the conference entitled "Orofacial Pain and Cancer" (Dolor Orofacial y Cancer) given at the VI Simposio International "Advances in Oral Cancer" on the 22 July, 2016 in San Sebastioan-Donostia, Spain. We have reviewed (pubmed-medline) from the most relevant literature including reviews, systematic reviews and clinical cases, the significant and evidence-based mechanisms and mediators of cancer-associated facial pain, the diverse types of cancers that can be present in the craniofacial region locally or from distant sites that can refer to the orofacial region, cancer therapy that may induce pain in the orofacial region as well as discussed some of the new advancements in cancer pain therapy. There is still a lack of understanding of cancer pain pathophysiology since depends of the intrinsic heterogeneity, type and anatomic location that the cancer may present, making more challenging the creation of better therapeutic options. Orofacial pain can arise from regional or distant tumor effects or as a consequence of cancer therapy. The clinician needs to be aware that the pain may present the characteristics of any other orofacial pain disorder so a careful differential diagnosis needs to be given. Cancer pain diagnosis is made by exclusion and only can be reached after a thorough medical history, and all the common etiologies have been carefully investigated and ruled out. The current management tools are not optimal but there is hope for new, safer and effective therapies coming in the next years.

The objective of this study was to categorize the ischemic thoracic pain in women in light of the theory Of Unpleasant Symptoms. The study was designed to be descriptiveexploratory with a qualitativequantitative approach. The information was collected by means of a semistructured interview and samples as gathered with information supplied by 30 women who were diagnosed with unstable heart pain or acute heart attack at San Rafael Hospital and at San Sebastián Clinic in Giradot from July to November 2005. The results showed women between 50 and 95 years of age, the majority classified to be within a low social class and level of education. As to the physiological factor, the most representative pathologic background from cardiovascular origin was high blood pressure, followed by diabetes. Within the psychological factors, the most representative category in frequency was "what women believe and know about the symptoms and the disease" and in the situational factors "heat affects me". In terms of the quality dimension, the outstanding category was "major commitment with being a human being". The symptom was referred to a severe intensity in 93% of the cases, and the average grade was 9,48 in a visual analogue scale. Within the consequences of the symptom, the most representative was "Controlling physical activity". The most frequent secondary symptoms were "vomit", "dizziness" and "headache". A symptomatic profile is observed, which is expressed with a linguistic richness and that shows concatenation processes within her health experience that enables us to understand her situation better and consequently to provide adequate care.La enfermedad coronaria ocupa el primer lugar como causa de mortalidad en la población femenina en Colombia

    Statins are used for the prevention and treatment of cardiovascular disease. The treatment is quite safe but not free of side effects, particularly muscle pain. Fear of pain may prevent patients from carrying out exercise or diminish their motivation to return and engage in it, even though both the statins and the exercise have a proven benefit in both treatment and prevention, and a synergistic effect enhances this benefit. Prevalence of muscular pain ranges from 1-30%. Pain usually appears at the beginning of treatment, but can occur even after months and under any of the existing agents. The creatine phosphokinase (CPK) enzyme level may rise, but not necessarily. Increases to exceptional values (10 times the upper normal level) are relatively rare and rhabdomyolysis is extremely rare. The risk increases with age, co-morbidities and especially when taken concurrently with drugs that are metabolized in a similar pathway. Pain usually passes within a month after discontinuing treatment, but may persist for six months or more. Studies have examined the effect of statin therapy on the ability to perform physical activity, but results are inconsistent. The increased rise of CPK was observed under statin therapy, a tendency that increased with age. However, it was not accompanied by an increased incidence of muscle pain or rhabdomyolysis. Considering the above we recommend encouraging patients to exercise. However, patients should be instructed to report new or worsening muscular pains. Discontinuation, lowering dose or replacement should be considered when pain is suspected to be related with treatment.

    Background Age-related changes occur in both the peripheral and central nervous system, yet little is known about the influence of chronic pain on pain sensitivity in older persons. The aim of this study was to investigate pain sensitivity in elders with chronic neck pain compared to healthy elders. Methods Thirty elderly women with chronic neck pain and 30 controls were recruited. Measures of pain sensitivity included pressure pain thresholds, heat/cold pain thresholds and suprathreshold heat pain responses. The pain measures were assessed over the cervical spine and at a remote site, the tibialis anterior muscle. Results Elders with chronic neck pain had lower pressure pain threshold over the articular pillar of C5-C6 and decreased cold pain thresholds over the cervical spine and tibialis anterior muscle when compared with controls (p pain thresholds and suprathreshold heat pain responses (p > 0.05). Conclusion The presence of pain hypersensitivity in elderly women with chronic neck pain appears to be dependent on types of painful stimuli. This may reflect changes in the peripheral and central nervous system with age. PMID:26039149

    However, the cerebral processing of hyperalgesia and allodynia is still controversially discussed. In recent years, neuroimaging methods (functional magnetic resonance imaging, fMRI; magnetoencephalography, MEG; positron emission tomography, PET have provided new insightsinto the aberrant cerebral processing of neuropathic pain. Thepresent paper reviews different cerebral mechanisms contributing to chronicity processes in neuropathic pain syndromes. These mechanisms include reorganisation of cortical somatotopic maps in sensory or motor areas (highly relevant for phantom limb pain and CRPS, increased activity in primary nociceptive areas, recruitment of new cortical areas usually not activated by nociceptive stimuli and aberrant activity in brain areas normally involved in descending inhibitory pain networks. Moreover, there is evidence from PET studies for changes of excitatory and inhibitory transmitter systems. Finally, advanced methods of structural brain imaging (voxel-based morphometry, VBM show significant structural changes suggesting that chronic pain syndromes may be associated with neurodegeneration.

    2018-01-01

    Abdominal pain is one of the common symptoms reported by children in urgent care clinics. While most children tend to have self-limiting conditions, the treating pediatrician should watch out for underlying serious causes like intestinal obstruction and perforation peritonitis, which require immediate referral to an emergency department (ED). Abdominal pain may be secondary to surgical or non-surgical causes, and will differ as per the age of the child. The common etiologies for abdominal pain presenting to an urgent care clinic are acute gastro-enteritis, constipation and functional abdominal pain; however, a variety of extra-abdominal conditions may also present as abdominal pain. Meticulous history taking and physical examination are the best tools for diagnosis, while investigations have a limited role in treating benign etiologies.

  18. Methadone for Cancer Pain

    Directory of Open Access Journals (Sweden)

    Eric E. Prommer

    2010-07-01

    Full Text Available Pain is one of the most common and incapacitating symptoms experienced by patients with advanced cancer. Methadone is a potent opioid with strong affinity for the µ opioid receptor. In addition to being a potent µ opioid receptor ligand, methadone blocks the N-methyl-D-aspartic acid receptor and modulates neurotransmitters involved in descending pain modulation. These 3 properties enhance analgesic activity. Methadone’s lack of active metabolites makes it an attractive option when opioid responsiveness declines and renal insufficiency complicates opioid therapy. A lipophilic opioid, methadone can be given by multiple routes. Clinical trial data show equivalence with morphine as an analgesic in moderate to severe cancer pain. Further investigations are needed to define the role of methadone in the management of breakthrough pain and neuropathic pain and to determine whether it is truly superior to morphine, the gold standard of cancer analgesia.

    Full Text Available Pain has several causes. It can be caused not only by operative trauma or cancer. Some patients suffer from pain as a result of being victims of violence. The aim of the study was to introduce diagnosis and treatment of pain problems in patients who are victims of violence, from a physician’s and a psychologist’s common perspective. Physical pain-related primary effects experienced by the victims of domestic violence go far beyond the results which are noticeable directly and confirmed visually in a forensic examination. In the present paper we introduce an ‘invisible’ group of secondary effects of violence. They appear in time, often after several years, in the form of a variety of psychosomatic disorders. The body is devastated insidiously and the secondary effects are visible as vegetative symptoms, a variety of psychosomatic disorders and pain, difficult to diagnose and treat.

    The Southern Patagonian Andes are an ideal setting to study the impact of Late-Cenozoic climate cooling and onset of glaciations impact on the erosional history of mountain belts. The lack of tectonic activity during the last ~12 Myr makes the denudation history mainly controlled by surface processes, not by tectonics. Moreover, the glaciations history of Patagonia shows the best-preserved records within the southern hemisphere (with the exception of Antarctica). Indeed, the dry climate on the leeward side of Patagonia and the presence of lava flows interbedded with glacial deposits has allowed an exceptional preservation of late Cenozoic moraines with precise dating using K-Ar analyses on lava flow. The chronology of moraines reveals a long history covering all the Quaternary, Pliocene, and up to the Upper Miocene. The early growth of large glaciers flowing on eastern foothills started at ~7-6 Myr, while the maximum ice-sheet extent dates from approximately 1.1 Myr. In order to quantify the erosion history of the Southern Patagonian Andes and compare it to the glaciations sediment record, we collected samples along an age-elevation profile for low-temperature thermochronology in the eastern side of the mountain belt (Torres del Paine massif). The (U-Th)/He age-elevation relationship shows a clear convex shape providing an apparent long-term exhumation rate of ~0.2 km/Myr followed by an exhumation rate increase at ~6 Myr. Preliminary results of 4He/3He thermochronometry for a subset of samples complete the erosion history for the Plio-Pleistocene epoch. We used inverse procedure predicting 4He distributions within an apatite grain using a radiation-damage and annealing model to quantify He-diffusion kinetics in apatite. The model also allows quantifying the impact of potential U-Th zonation throughout each apatite crystal. Inversion results reveal a denudation history composed by a pulse of denudation at ~6 Ma, as suggested by the age-elevation relationship

    Full Text Available Abstract Introduction: Chronic neck pain is associated with significant health costs and loss of productivity at work. Objective: to assess pain and disability in individuals with chronic neck pain. Methods: 31 volunteers with chronic neck pain, mean age 29, 65 years, were assessed using the McGill Pain Questionnaire in Brazilian version (Br-MPQ and Neck Disability Index (NDI. The Br-MPQ analysis was performed based on the numerical values associated with the words selected to describe the experience of pain (Pain Rating Index - PRI, and present pain intensity (PPI. NDI was used to evaluate the influence of neck pain in performance of everyday tasks. Finally, we investigated the association between PPI and NDI. Results: PRI revealed that the most significant dimension was the sensory pain (70%, and the number of chosen words was 10 (2,62 out of 20 words. Mean PPI value was 1,23 (0,76 in five points; 40% of participants described pain intensity as moderate. NDI score was 9,77 (3,34, indicating mild disability. There was a positive association between disability and pain intensity (r = 0,36; p =0,046. Pain intensity and duration of pain were not associated. Conclusions: Findings of this study identified important information related to neck pain experienced by patients when suffering from chronic neck pain, moreover, the association between disability and pain intensity reinforces the importance of complementary investigation of these aspects to optimize function in them.

METHOD: Descriptive qualitative study conducted in an emergency service in southern Brazil. Data was collected in October 2013, through semi-structured interviews with 29 individuals who reported pain after physical trauma, regardless of the triggering factor. To process the data, we used a Content Analysis technique, subject modality. RESULTS: Two categories emerged: Factors that influence the perception of pain resulting from trauma and, Consequences of acute pain due to trauma. The acute pain sensation was influenced by biological, emotional, spiritual and socio-cultural factors and induced biological and emotional consequences for individuals. CONCLUSION: The health professionals need to consider the factors that influence soreness and its consequences for the proper assessment and management of pain resulting from trauma.

  10. The painful shoulder

    Hartl, P.W.

    The painful shoulder syndrome is very common. Diagnosis and differential diagnosis may be difficult. Shoulder pain may be caused by local processes or systemic diseases or can be referred. Periarthritis humeroscapularis (frozen shoulder) is the most common cause of painful shoulder syndrome. Biomechanical factors concerning the rotator cuff are involved in the etiopathogenesis of these pain syndromes. The therapy of frozen shoulder includes physical treatment, antirheumatic drugs, or X-ray treatment. Surgical measures may become necessary. In the course of rheumatoid arthritis the shoulder may be involved. Milwaukee-shoulder-syndrome has been described recently in crystal deposit diseases. Shoulder pain may be referred by mechanical irritations of nerve roots in the course of degenerative lesions of the cervical spine and also in the course of internal diseases of the heart, the lungs, or the gastrointestinal tract. In cases of shoulder pain without pathological data from arthrological, radiological or laboratory studies, one should always consider localized fibromyalgia in the shoulder-neck-region. The precise diagnosis of shoulder pain is an important prerequisite for treatment, the success of which should not be judged as pessimistic as it has been commonly done in the past. (orig.) [de

    Conclusion:. Pro-nociception, expressed by less efficient CPM and high temporal summation that usually accompanies clinical painful conditions, seems to “normalize” with chronicity of the pain syndrome. This is despite continuing pain, suggesting that pro-nociceptivity in pain syndromes is multifactorial. Because the pain modulation profile affects success of therapy, this suggests that different drugs might express different efficacy pending on duration of the pain in patients with PDN.

  12. Language and the pain experience.

    People in persistent pain have been reported to pay increased attention to specific words or descriptors of pain. The amount of attention paid to pain or cues for pain (such as pain descriptors), has been shown to be a major factor in the modulation of persistent pain. This relationship suggests the possibility that language may have a role both in understanding and managing the persistent pain experience. The aim of this paper is to describe current models of neuromatrices for pain and language, consider the role of attention in persistent pain states and highlight discrepancies, in previous studies based on the McGill Pain Questionnaire (MPQ), of the role of attention on pain descriptors. The existence of a pain neuromatrix originally proposed by Melzack (1990) has been supported by emerging technologies. Similar technologies have recently allowed identification of multiple areas of involvement for the processing of auditory input and the construction of language. As with the construction of pain, this neuromatrix for speech and language may intersect with neural systems for broader cognitive functions such as attention, memory and emotion. A systematic search was undertaken to identify experimental or review studies, which specifically investigated the role of attention on pain descriptors (as cues for pain) in persistent pain patients. A total of 99 articles were retrieved from six databases, with 66 articles meeting the inclusion criteria. After duplicated articles were eliminated, the remaining 41 articles were reviewed in order to support a link between persistent pain, pain descriptors and attention. This review revealed a diverse range of specific pain descriptors, the majority of which were derived from the MPQ. Increased attention to pain descriptors was consistently reported to be associated with emotional state as well as being a significant factor in maintaining persistent pain. However, attempts to investigate the attentional bias of specific pain

The nine-item version consists of seven sensory items (burning, tingling/prickling, light touching, sudden pain attacks/electric shock-type pain, cold/heat, numbness, and slight pressure, a pain course pattern item, and a pain radiation item. The seven-item version consists only of the sensory items. Total scores of both versions discriminate average pain-severity levels (mild, moderate, and severe, but their ability to discriminate individual item severity has not been evaluated.Methods: Data were from a cross-sectional, observational study of six neuropathic pain conditions (N=624. Average pain severity was evaluated using the Brief Pain Inventory-Short Form, with severity levels defined using established cut points for distinguishing mild, moderate, and severe pain. The Wilcoxon rank sum test was followed by ridit analysis to represent the probability that a randomly selected subject from one average pain-severity level had a more favorable outcome on the specific painDETECT item relative to a randomly selected subject from a comparator severity level.Results: A probability >50% for a better outcome (less severe pain was significantly observed for each pain symptom item. The lowest probability was 56.3% (on numbness for mild vs moderate pain and highest probability was 76.4% (on cold/heat for mild vs severe pain. The pain radiation item was significant (P<0.05 and consistent with pain symptoms, as well as with total scores for both painDETECT versions; only the pain course item did not differ.Conclusion: painDETECT differentiates severity such that the ability to discriminate average pain also distinguishes individual pain item severity in an interpretable manner.

    sistema nervioso periférico. No queda claro si el efecto analgésico local es de clase específico o un fármaco específico. MÉTODO: Para responder a esa pregunta, utilizamos tres diferentes antagonistas del receptor H1 (pirilamina, prometazina y cetirizina, administrados directamente en la pata del ratón, por vía intraperitoneal o por bloqueo de nervio periférico en modelo de dolor inducido por formalina. Observamos el efecto de los fármacos en el comportamiento del número de elevaciones de la pata. RESULTADOS: En la fase I, la pirilamina local redujo el número de elevaciones de la pata de forma dosis dependiente. En la dosis más alta, la reducción fue de un 97,8%. Para la prometazina, la disminución fue de un 92% y para la cetizirina de 23.9%. En la fase II, la pirilamina redujo el número de elevaciones de la pata en un 93,5%, la prometazina, un 78,2% y la cetirizina un 80,1%. La administración de los fármacos por vía intraperitoneal no alteró el comportamiento doloroso. Cuando se usaron para bloqueo del nervio periférico en la fase I, la pirilamina redujo el número de elevaciones de la pata en un 96,7%, la prometazina en un 73,3% y la cetirizina en un 23,9%. En la fase II, la pirilamina redujo un 86,6%, la prometazina un 64,4% y la cetirizina un 19,9%.

Arm pain without strict diagnosis is often related to activity, work-related activity in particular, and is often seen in patients with physically demanding work. Psychological factors such as catastrophic thinking, symptoms of depression, and heightened illness concern determine a substantial percentage of the disability associated with puzzling hand and arm pains. Ergonomic modifications can help to control symptoms, but optimal health may require collaborative management incorporating psychosocial and psychological elements of illness.

    System planning for the Alberta Electric System Operator's (AESO) southern system was discussed in view of the growing interest in developing wind energy resources in the province. While Alberta currently has a total of 11,500 MW of installed wind power, southern Alberta has a very small capability for interconnecting additional wind resources. There are 3 main agencies involved in system planning for the southern region: (1) the Alberta Utilities Commission (AUC), (2) the AESO, and (3) the transmission facility owners. Transmission needs are studied by the AESO, who then applies to the AUC for approval. Transmission facility owners also apply to the AUC for approval to construct facilities. The AESO's roles are to operate the wholesale electricity market; plan the transmission system; arrange access for loads and generation; and oversee transmission system operation. The AESO is an independent agency with a public interest mandate. The AESO's queue management process has been designed to facilitate non-discriminatory system access. Development options currently being considered by the AESO include a 240 kV AC transmission line; a 500 kV AC transmission line; a 765 kV AC transmission line; a high voltage direct current (HVDC) system; and a voltage source converter (VSC) HVDC system. Radial and looped configurations are also being considered. The AESO is currently conducting a participant involvement program that involves open houses with the Canadian Wind Energy Association (CanWEA) and other provincial stakeholders. tabs., figs.

  1. Conditioned pain modulation in patients with nonspecific chronic back pain with chronic local pain, chronic widespread pain, and fibromyalgia.

    Findings considering conditioned pain modulation (CPM) in chronic back pain (CBP) are contradictory. This might be because many patients with CBP report pain in further areas of the body, and altered CPM might influence spatial extent of pain rather than CBP per se. Therefore, we compared CPM in patients with CBP with different pain extent. Patients with fibromyalgia syndrome (FMS), for whom CPM impairment is reported most consistently, were measured for comparison. Based on clinical evaluation and pain drawings, patients were categorized into chronic local back pain (CLP; n = 53), chronic widespread back pain (CWP; n = 32), and FMS (n = 92). Conditioned pain modulation was measured by the difference in pressure pain threshold (test stimuli) at the lower back before and after tonic heat pain (conditioning stimulus). We also measured psychosocial variables. Pressure pain threshold was significantly increased in CLP patients after tonic heat pain (P pain modulation in CLP was significantly higher than that in CWP and FMS (P painful areas (0-10) were associated with lower CPM (r = 0.346, P = 0.001) in CBP but not in FMS (r = -0.013, P = 0.903). Anxiety and depression were more pronounced in FMS than in CLP or CWP (P values pain inhibition seem to be more indicated the higher the pain extent.

    The goal of this study was to evaluate whether preoperative pressure pain sensitivity testing is predictive of postoperative surgical pain. Female subjects undergoing lower abdominal gynecologic surgery were studied. A pressure algometer was used preoperatively to determine the pressure pain threshold and tolerance. A visual analog scale (VAS) was used to assess postoperative pain. A State-Trait Anxiety Inventory was used to assess patients' anxiety. Subjects received intravenous patient-controlled analgesia for postoperative pain control. The preoperative pain threshold and tolerance were compared with the postoperative VAS pain score and morphine consumption. Forty women were enrolled. Their preoperative pressure pain threshold and tolerance were 141 +/- 65 kPa and 223 +/- 62 kPa, respectively. The VAS pain score in the postanesthesia care unit and at 24 h postoperatively were 81 +/- 24 and 31 +/- 10, respectively. Highly anxious patients had higher VAS pain scores in the postanesthesia care unit (P pain tolerance was significantly correlated with the VAS at 24 h postoperatively (P pain tolerance after fentanyl administration (mean, 272 +/- 68 kPa) correlated significantly with morphine consumption in the first 24 h postoperatively (P pain tolerance is significantly correlated with the level of postoperative pain. Pain tolerance assessment after fentanyl was administered and fentanyl sensitivity predicted the dose of analgesics used in the first 24 h after surgery. The algometer is thus a simple, useful tool for predicting postoperative pain and analgesic consumption.

  5. Postamputation pain: studies on mechanisms.

    Science.gov (United States)

    Nikolajsen, Lone

    2012-10-01

    Amputation is followed by both painful and non-painful phantom phenomena in a large number of amputees. Non-painful phantom sensations rarely pose any clinical problem, but 60-80% of all amputees also experience painful sensations (i.e. phantom pain) located to the missing limb. The severity of phantom pain usually decreases with time, but severe pain persists in 5-10% of patients. Pain in the residual limb (i.e. stump pain) is another consequence of amputation. Both stump and phantom pain can be very difficult to treat. Treatment guidelines used for other neuropathic pain conditions are probably the best approximation, especially for the treatment of stump pain. The aim of the present doctoral thesis was to explore some of the mechanisms underlying pain after amputation. Ten studies were carried out (I-X). My PhD thesis from 1998 dealt with pain before the amputation and showed that preamputation pain increases the risk of phantom pain after amputation (I). A perioperative epidural blockade, however, did not reduce the incidence of pain or abnormal sensory phenomena after amputation (II, III). The importance of sensitization before amputation for the subsequent development of pain is supported by study IV, in which pressure pain thresholds obtained at the limb before amputation were inversely related to stump and phantom pain after 1 week. Afferent input from the periphery is likely to contribute to postamputation pain as sodium channels were upregulated in human neuromas (VI), although neuroma removal did not always alleviate phantom pain (V). Sensitization of neurons in the spinal cord also seems to be involved in pain after amputation as phantom pain was reduced by ketamine, an NMDA-receptor antagonist. Another NMDA-receptor antagonist, memantine, and gabapentin, a drug working by binding to the δ2α-subunit of voltage-gated calcium channels, had no effect on phantom pain (VII-IX). Supraspinal factors are also important for pain after amputation as

    OBJECTIVES: To empirically assess the clinical effects of physiotherapy on pain in adults. DESIGN: Using meta-epidemiology, we report on the effects of a 'physiotherapy' intervention on self-reported pain in adults. For each trial, the group difference in the outcome 'pain intensity' was assessed...... as standardised mean differences (SMD) with 95% CIs. Stratified analyses were conducted according to patient population (International Classification of Diseases-10 classes), type of physiotherapy intervention, their interaction, as well as type of comparator group and risks of bias. The quality of the body...... 'no intervention' or of a sham-controlled design were selected. Only articles written in English were eligible. RESULTS: An overall moderate effect of physiotherapy on pain corresponding to 0.65 SD-units (95% CI 0.57 to 0.73) was found based on a moderate inconsistency (I(2)=51%). Stratified...

    Functional abdominal pain syndrome (FAPS) differs from the other functional bowel disorders; it is less common, symptoms largely are unrelated to food intake and defecation, and it has higher comorbidity with psychiatric disorders. The etiology and pathophysiology are incompletely understood. Because FAPS likely represents a heterogeneous group of disorders, peripheral neuropathic pain mechanisms, alterations in endogenous pain modulation systems, or both may be involved in any one patient. The diagnosis of FAPS is made on the basis of positive symptom criteria and a longstanding history of symptoms; in the absence of alarm symptoms, an extensive diagnostic evaluation is not required. Management is based on a therapeutic physician-patient relationship and empirical treatment algorithms using various classes of centrally acting drugs, including antidepressants and anticonvulsants. The choice, dose, and combination of drugs are influenced by psychiatric comorbidities. Psychological treatment options include psychotherapy, relaxation techniques, and hypnosis. Refractory FAPS patients may benefit from a multidisciplinary pain clinic approach.

    Science.gov (United States)

    Andersen, L T

    1985-01-01

    Development of a painful shoulder in the hemiplegic patient is a significant and serious problem, because it can limit the patient's ability to reach his or her maximum functional potential. Several etiologies of shoulder pain have been identified, such as immobilization of the upper extremity, trauma to the joint structures, including brachial plexus injuries, and subluxation of the gleno-humeral joint. A review of the literature explains the basic anatomy and kinesiology of the shoulder complex, the various etiologies of hemiplegic shoulder pain, and the pros and cons of specific treatment techniques. This knowledge is essential for the occupational therapist to evaluate effectively techniques used to treat the patient with hemiplegic shoulder pain. More effective management of this problem will facilitate the patient's ability to reach his or her maximum functional potential.

  15. Music for pain relief.

    The efficacy of music for the treatment of pain has not been established. To evaluate the effect of music on acute, chronic or cancer pain intensity, pain relief, and analgesic requirements. We searched The Cochrane Library, MEDLINE, EMBASE, PsycINFO, LILACS and the references in retrieved manuscripts. There was no language restriction. We included randomized controlled trials that evaluated the effect of music on any type of pain in children or adults. We excluded trials that reported results of concurrent non-pharmacological therapies. Data was extracted by two independent review authors. We calculated the mean difference in pain intensity levels, percentage of patients with at least 50% pain relief, and opioid requirements. We converted opioid consumption to morphine equivalents. To explore heterogeneity, studies that evaluated adults, children, acute, chronic, malignant, labor, procedural, or experimental pain were evaluated separately, as well as those studies in which patients chose the type of music. Fifty-one studies involving 1867 subjects exposed to music and 1796 controls met inclusion criteria. In the 31 studies evaluating mean pain intensity there was a considerable variation in the effect of music, indicating statistical heterogeneity ( I(2) = 85.3%). After grouping the studies according to the pain model, this heterogeneity remained, with the exception of the studies that evaluated acute postoperative pain. In this last group, patients exposed to music had pain intensity that was 0.5 units lower on a zero to ten scale than unexposed subjects (95% CI: -0.9 to -0.2). Studies that permitted patients to select the music did not reveal a benefit from music; the decline in pain intensity was 0.2 units, 95% CI (-0.7 to 0.2). Four studies reported the proportion of subjects with at least 50% pain relief; subjects exposed to music had a 70% higher likelihood of having pain relief than unexposed subjects (95% CI: 1.21 to 2.37). NNT = 5 (95% CI: 4 to 13). Three

    The issues specific to trigeminal pain include the complexity of the region, the problematic impact on daily function and significant psychological impact (J Dent, 43, 2015, 1203). By nature of the geography of the pain (affecting the face, eyes, scalp, nose, mouth), it may interfere with just about every social function we take for granted and enjoy (J Orofac Pain, 25, 2011, 333). The trigeminal nerve is the largest sensory nerve in the body, protecting the essential organs that underpin our very existence (brain, eyes, nose, mouth). It is no wonder that pain within the trigeminal system in the face is often overwhelming and inescapable for the affected individual. © 2016 John Wiley & Sons A/S.

    There is a lot of unrelieved pain in developing countries. Here is a story from Bali, Indonesia, about a woman with advanced malignancy, who is in unbelievable agony. Expensive chemotherapy is available to her. But although the necessary medications for relieving her pain are available in hospitals, they do not reach the patient, in her home, or even when she is admitted to the hospital, because of ignorance of the medical profession about pain management and because of unnecessary regulatory restrictions. The woman's pain affects the whole family, endangering the family's income and the future of her children. The intervention of palliative care during part of her life gives her some relief, only for the agony to be repeated by pointless chemotherapy and neglect of the suffering during admission to the hospital. Whatever relief could be given to her was because of the intervention of a volunteer with no schooling in medicine or palliative care.

  20. Pain stress and headache.

    Panerai, Alberto E

    2012-05-01

    The association between pain and stress is an old one, but still it is not really clear who comes first. Pain induces stress, and stress induces pain. Pain is part of our homeostatic system and in this way is an emotion, i.e., it tells us that something is out-of-order (control), and emotion drives our behavior and one behavior is stress response. Stress comes from ourselves: the imagination we have or would like to have of us, from the image others give of us, from the goals we assume it is necessary to reach for our well-being or the goals others want us to fulfill. Stress comes from our social condition and the condition we would like, stress comes from dangerous situations we cannot control. Headache easily fits in the picture.

  2. Conceptualizing suffering and pain.

    Bueno-Gómez, Noelia

    2017-09-29

    This article aims to contribute to a better conceptualization of pain and suffering by providing non-essential and non-naturalistic definitions of both phenomena. Contributions of classical evidence-based medicine, the humanistic turn in medicine, as well as the phenomenology and narrative theories of suffering and pain, together with certain conceptions of the person beyond them (the mind-body dichotomy, Cassel's idea of persons as "intact beings") are critically discussed with such purpose. A philosophical methodology is used, based on the review of existent literature on the topic and the argumentation in favor of what are found as better definitions of suffering and pain. Pain can be described in neurological terms but cognitive awareness, interpretation, behavioral dispositions, as well as cultural and educational factors have a decisive influence on pain perception. Suffering is proposed to be defined as an unpleasant or even anguishing experience, severely affecting a person at a psychophysical and existential level. Pain and suffering are considered unpleasant. However, the provided definitions neither include the idea that pain and suffering can attack and even destroy the self nor the idea that they can constructively expand the self; both perspectives can b e equally useful for managing pain and suffering, but they are not defining features of the same. Including the existential dimension in the definition of suffering highlights the relevance of suffering in life and its effect on one's own attachment to the world (including personal management, or the cultural and social influences which shape it). An understanding of pain and suffering life experiences is proposed, meaning that they are considered aspects of a person's life, and the self is the ever-changing sum of these (and other) experiences. The provided definitions will be useful to the identification of pain and suffering, to the discussion of how to relieve them, and to a better understanding

    This study describes surgical colorectal cancer patients' pain levels, recovery activities, beliefs and expectations about pain, and satisfaction with pain management. A convenience sample of 50 adult inpatients who underwent colorectal surgery for cancer participated. Patients were administered the modified American Pain Society Patient Outcome Questionnaire on postoperative day 2 and asked to report on their status in the preceding 24 hours. Patients reported low current (mean 1.70) and average (mean 2.96) pain scores but had higher scores and greater variation for worst pain (mean 5.48). Worst pain occurred mainly while turning in bed or mobilizing, and 25% of patients experienced their worst pain at rest. Overall, patients expected to have pain after surgery and were very satisfied with pain management. Patients with worst pain scores >7 reported interference with recovery activities, mainly general activity (mean 5.67) and walking ability (mean 5.15). These patients were likely to believe that "people can get addicted to pain medication easily" (mean 3.39 out of 5) and that "pain medication should be saved for cases where pain gets worse" (mean 3.20 out of 5). These beliefs could deter patients from seeking pain relief and may need to be identified and addressed along with expectations about pain in the preoperative nursing assessment.

    Alleviation of pain, by either medical or surgical therapy, is accompanied by transition from less efficient, or pro-nociceptive, to efficient conditioned pain modulation (CPM). Spontaneous decrease or resolution of pain with disease progression is reported for some patients with painful diabetic neuropathy (PDN). To explore whether CPM changes similarly in parallel to spontaneous resolution of pain in PDN patients. In this cross-sectional study, thirty-three patients with PDN underwent psychophysical assessment of pain modulation on the forearm, remote from the clinical pain. Pain duration was not correlated with neuropathic pain intensity, yet, it correlated with CPM efficiency; patients with longer pain duration had same pain level, but more efficient CPM than those with short-pain duration (ρ = -0.417; P = 0.025, Spearman correlation). Patients with pain more than 2 years (median split) expressed efficient CPM that was not different from that of healthy controls. These patients also had lower temporal summation of pain than the short-pain duration patients group ( P < 0.05). The 2 patient groups did not differ in clinical pain characteristics or use of analgesics. Pro-nociception, expressed by less efficient CPM and high temporal summation that usually accompanies clinical painful conditions, seems to "normalize" with chronicity of the pain syndrome. This is despite continuing pain, suggesting that pro-nociceptivity in pain syndromes is multifactorial. Because the pain modulation profile affects success of therapy, this suggests that different drugs might express different efficacy pending on duration of the pain in patients with PDN.

En este estudio se busca evidenciar si existe un uso diferencial de microhábitats de las infrapoblaciones de Aggregata patagonica entre dos zonas del tracto digestivo de su hospedador definitivo, el pulpo Enteroctopus megalocyathus. Para ello, se examinaron 40 ejemplares de Ancud y 37 de Quellón, provenientes de las capturas artesanales de la Isla de Chiloé. El tamaño y la densidad de los ooquistes se cuantificaron en el ciego y el intestino del hospedador. Además, se efectuaron observaciones histológicas para determinar cuantitativamente la ocurrencia de los distintos estados de desarrollo del parásito. En Ancud el 80 % de los pulpos estaban parasitados en el ciego y el intestino, mientras que en Quellón era el 100 %. Se determinaron cuatro estados de desarrollo (microgametos, cigotos, esporoquistes inmaduros y maduros. Los ooquistes de A. patagonica fueron más pequeños y abundantes en el ciego, pero la cobertura fue mayor en el intestino. Además, la densidad y cobertura aumenta en pocos meses entre una muestra y otra. Al parecer, A. patagonica no usaría a los dos microhábitats como lugares de preferencia para pasar los diferentes estados de desarrollo, sino más bien, y según las condiciones del microhábitat, en el intestino crecerían más los ooquistes pero en menos cantidad, ocupando una mayor superficie del microhábitat, contrario a lo que ocurre en el ciego.

    Full Text Available Background and Objectives: Prayer is one of the most important religious ordinances and is one of the necessities of Islam. In spite of the progression of medicine science, it is sometimes seen that the mundane subjects become hopeless in curing physical diseases and this time, the hopeless man appeals to the Lord God. This review study was conducted to examine the positive and negative views regarding effectsof prayer on physical pains. Methods: This review article was carried on by studying about 30 related original articles and different scientific texts.  Results:In various studies, it is demonstrated that Islamic worships especially prayer are effective in treating most acute and chronic pains. But despite this, some studies indicate that there is no effectiveness or even there are negative effects of prayer on some physical pains. Conclusion: With regard to the above mentioned results,most studies support the positive effects of prayer on physical pains. So the medical staffs should alsopay attention to this besides medicinal remedies. In addition, by emphasizing on and advertising aboutthe advantages of practices likeprayer in the treatment of chronic pains, it would be possible to prevent people, especially the youth, from taking inadmissible drugs such as alcohol, narcotics or other illegal drugs. Further studies are recommended to explore the effects of prayer on different acute and chronic physical pains.

  11. Functional abdominal pain.

    Grover, Madhusudan; Drossman, Douglas A

    2010-10-01

    Functional abdominal pain syndrome (FAPS) is a relatively less common functional gastrointestinal (GI) disorder defined by the presence of constant or frequently recurring abdominal pain that is not associated with eating, change in bowel habits, or menstrual periods (Drossman Gastroenterology 130:1377-1390, 2006), which points to a more centrally targeted (spinal and supraspinal) basis for the symptoms. However, FAPS is frequently confused with irritable bowel syndrome and other functional GI disorders in which abdominal pain is associated with eating and bowel movements. FAPS also differs from chronic abdominal pain associated with entities such as chronic pancreatitis or chronic inflammatory bowel disease, in which the pain is associated with peripherally acting factors (eg, gut inflammation or injury). Given the central contribution to the pain experience, concomitant psychosocial disturbances are common and strongly influence the clinical expression of FAPS, which also by definition is associated with loss of daily functioning. These factors make it critical to use a biopsychosocial construct to understand and manage FAPS, because gut-directed treatments are usually not successful in managing this condition.

    2016-10-01

    Although pelvic pain is a symptom of several structural anorectal and pelvic disorders (eg, anal fissure, endometriosis, and pelvic inflammatory disease), this comprehensive review will focus on the 3 most common nonstructural, or functional, disorders associated with pelvic pain: functional anorectal pain (ie, levator ani syndrome, unspecified anorectal pain, and proctalgia fugax), interstitial cystitis/bladder pain syndrome, and chronic prostatitis/chronic pelvic pain syndrome. The first 2 conditions occur in both sexes, while the latter occurs only in men. They are defined by symptoms, supplemented with levator tenderness (levator ani syndrome) and bladder mucosal inflammation (interstitial cystitis). Although distinct, these conditions share several similarities, including associations with dysfunctional voiding or defecation, comorbid conditions (eg, fibromyalgia, depression), impaired quality of life, and increased health care utilization. Several factors, including pelvic floor muscle tension, peripheral inflammation, peripheral and central sensitization, and psychosocial factors, have been implicated in the pathogenesis. The management is tailored to symptoms, is partly supported by clinical trials, and includes multidisciplinary approaches such as lifestyle modifications and pharmacological, behavioral, and physical therapy. Opioids should be avoided, and surgical treatment has a limited role, primarily in refractory interstitial cystitis. Copyright © 2016 Mayo Foundation for Medical Education and Research.

    OA is a painful joint disease that predominantly affects the elderly. Pain is the primary symptom of OA, and it can present as either intermittent or constant. OA pain mechanisms are complex and have only recently been determined. Both peripheral and central processes are involved in creating the OA pain experience, making targeted therapy problematic. Nociceptive, inflammatory and neuropathic pains are all known to occur in OA, but to varying degrees in a patient- and time-specific manner. A better understanding of these multifactorial components of OA pain will lead to the development of more effective and safer pain treatments.

    In connection with the investigations of the caesium-137, body burden of Finnish Lapps several measurements of smaller groups of people living in Southern Finland were carried out. In November 1961 eleven Helsinki inhabitants, five men and six women, 15 to 54 yr. old, were counted for caesium-137 and potassium in Stockholm. None of these persons were laboratory workers, two were schoolboys. They were apparently healthy. Their diet was studied by the interview method. Ten of these people were counted again in the mobile whole-body counter of the Radiochemical Department of the University of Helsinki one year later. The average body burden of caesium-137 in men (5, average age 29) had increased from 8.4 nc in November 1961 to 18.4 nc in November 1962, in women (5, average age 34) from 2.9 nc to 8.7 nc. Potassium contents were the same within 2% (men 140 g, women, 100 g) For more detailed studies larger control groups were selected at the beginning of 1963 and counted four times, in February, May, August and October. For the group of men 25 privates of an infantry battalion (age 19, average weight 65 kg), for women 24 girl students of a household school (age 22, average weight 60 kg), were selected. In both cases the diet could be checked in detail and could be considered to be an average Finnish diet. In addition, the individual food consumption of each subject was studied by interview with the aid of weighed samples. Caesium-137 contents of both diets were determined for the time periods between the measurements. In both groups the caesium-137 content remained about constant (men, 17,5 nc; women, 11 nc) until the end of June, when the caesium-137 content of milk and meat was approximately doubled within about one week. At the end of August the body burden of caesium-137 had increased in, both groups to about 40% above the spring level in the middle of October the men's values had increased by 22%, the women's values by 14% of the August level.

    Understanding the timing and magnitude of former glacier fluctuations is critical to decipher long-term climatic trends and to unravel both natural cycles and human impact on the current glacial behavior. Despite more than seven decades of research efforts, a unifying model of Holocene glacial fluctuations in Southern South America remains elusive. Here, we present the state-of-the-art regarding the timing of Holocene glacial fluctuation in southern Patagonia-Tierra del Fuego, with a focus on a new generation of high-resolution radiocarbon and 10Be surface exposure dating chronologies. Recently acquired evidence suggest that after receding from advanced Late Glacial positions, Patagonian glaciers were for the most part close to, or even behind, present ice margins during the Early Holocene. On the other hand, emerging chronologies indicate that in some areas there were extensive expansions (century scale?) that punctuated the warm interval. Subsequently, we have evidence of multiple millennial timescale glacial advances starting in the middle Holocene. Several glacial maxima are defined by moraines and other landforms from 7000 years ago to the 19th century, with a gap sometime between 4,500 and 2,500 years ago. The last set of advances began around 800-600 years ago. Although glacial activity is documented in Patagonia at the same time as the European Little Ice Age, the extent of these glacial events are less prominent than those of the mid-Holocene. The causes that may explain these glacial fluctuations remain elusive. Finally, we discuss ongoing efforts to better define the timing and extent of Holocene glaciations in southern South America, and to establish the basis to test competing hypothesis of regional Holocene climate variability.

    Full Text Available Cancer pain is multifactorial and complex. The impact of cancer pain is devastating, with increased morbidity and poor quality of life, if not treated adequately. Cancer pain management is a challenging task both due to disease process as well as a consequence of treatment-related side-effects. Optimization of analgesia with oral opioids, adjuvant analgesics, and advanced pain management techniques is the key to success for cancer pain. Early access of oral opioid and interventional pain management techniques can overcome the barriers of cancer pain, with improved quality of life. With timely and proper anticancer therapy, opioids, nerve blocks, and other non-invasive techniques like psychosocial care, satisfactory pain relief can be achieved in most of the patients. Although the WHO Analgesic Ladder is effective for more than 80% cancer pain, addition of appropriate adjuvant drugs along with early intervention is needed for improved Quality of Life. Effective cancer pain treatment requires a holistic approach with timely assessment, measurement of pain, pathophysiology involved in causing particular type of pain, and understanding of drugs to relieve pain with timely inclusion of intervention. Careful evaluation of psychosocial and mental components with good communication is necessary. Barriers to cancer pain management should be overcome with an interdisciplinary approach aiming to provide adequate analgesia with minimal side-effects. Management of cancer pain should comprise not only a physical component but also psychosocial and mental components and social need of the patient. With risk-benefit analysis, interventional techniques should be included in an early stage of pain treatment. This article summarizes the need for early and effective pain management strategies, awareness regarding pain control, and barriers of cancer pain.

    To characterize pain related to primary burning mouth syndrome (BMS) in terms of intensity, interference, and distress caused by the pain, as well as factors influencing the pain across a period of 2 weeks, and to study the use of coping and management strategies on a daily basis. Fifty-two female patients with primary BMS completed a 2-week pain diary. Pain intensity, interference, distress, and mood on a 0 to 10 numeric rating scale (NRS), as well as pain amplifying and alleviating factors, were recorded three times a day. The use of treatments (medication or other means) and coping strategies were recorded at the end of each day. Coefficient of variation, repeated measures analysis of variance, and correlative methods were used to assess the between- and within-subject variation, pain patterns, and associations between various pain scores. The overall mean pain intensity score of the 14 diary days was 3.1 (SD: 1.7); there was considerable variation in pain intensity between patients. Most patients experienced intermittent pain. On average, pain intensity increased from the morning to the evening. Intercorrelations between pain intensity, interference, distress, and mood were high, varying between rs = .75 and rs = .93 (P < .001). Pungent or hot food or beverages, stress, and tiredness were the most frequently mentioned pain-amplifying factors. The corresponding pain-alleviating factors were eating, sucking pastilles, drinking cold beverages, and relaxation. Thirty (58%) patients used pain medication and 35% reported using other means to alleviate their BMS pain. There was large variation in the use of coping strategies -between subjects. There were considerable differences in pain, in factors influencing the pain, and in pain behavior across BMS patients. This indicates that patient information and education as well as treatment of BMS pain should be individualized.

  3. Fear of pain in children and adolescents with neuropathic pain and complex regional pain syndrome.

    A significant proportion of children and adolescents with chronic pain endorse elevated pain-related fear. Pain-related fear is associated with high levels of disability, depressive symptoms, and school impairment. Because of faulty nerve signaling, individuals with neuropathic pain and complex regional pain syndrome may be more prone to develop pain-related fear as they avoid use of and neglect the affected body area(s), resulting in exacerbated symptoms, muscle atrophy, maintenance of pain signaling, and ongoing pain-related disability. Not surprisingly, effective treatments for elevated pain-related fears involve exposure to previously avoided activities to downregulate incorrect pain signaling. In the context of intensive interdisciplinary pain treatment of youth with neuropathic pain, decreasing pain-related fear is associated with improved physical and psychological functioning, whereas high initial pain-related fear is a risk factor for less treatment responsiveness. An innovative approach to targeting pain-related fear and evidence of a neural response to treatment involving decoupling of the amygdala with key fear circuits in youth with complex regional pain syndrome suggest breakthroughs in our ability to ameliorate these issues.

  4. The periodontal pain paradox: Difficulty on pain assesment in dental patients (The periodontal pain paradox hypothesis

    Full Text Available In daily dental practice, the majority of patients’ main complaints are related to pain. Most patients assume that all pains inside the oral cavity originated from the tooth. One particular case is thermal sensitivity; sometimes patients were being able to point the site of pain, although there is neither visible caries nor secondary caries in dental radiograph. In this case, gingival recession and dentin hypersensitivity are first to be treated to eliminate the pain. If these treatments failed, pain may misdiagnose as pulpal inflammation and lead to unnecessary root canal treatment. Study in pain during periodontal instrumentation of plaque-related periodontitis revealed that the majority of patients feel pain and discomfort during probing and scaling. It seems obvious because an inflammation, either acute or chronic is related to a lowered pain threshold. However, in contrast, in this case report, patient suffered from chronic gingivitis and thermal sensitivity experienced a relative pain-free sensation during probing and scaling. Lowered pain threshold which accompanied by a blunted pain perception upon periodontal instrumentation is proposed to be termed as the periodontal pain paradox. The objective of this study is to reveal the possibility of certain factors in periodontal inflammation which may involved in the periodontal pain paradox hypothesis. Patient with thermal hypersensitivity who was conducted probing and scaling, after the relative pain-free instrumentation, thermal hypersensitivity rapidly disappeared. Based on the successful periodontal treatment, it is concluded that chronic gingivitis may modulate periodontal pain perception which termed as periodontal pain paradox

    The Southern Ocean includes the only latitude band where the ocean circles the earth unobstructed by continental boundaries. This accident of geography has profound consequences for global ocean circulation, biogeochemical cycles, and climate. The Southern Ocean connects the ocean basins and links the shallow and deep limbs of the overturning circulation (Rintoul et al., 2001). The ocean's capacity to moderate the pace of climate change is therefore influenced strongly by the Southern Ocean's...

    Even though painful experiences are employed within social rituals across the world, little is known about the social effects of pain. We examined the possibility that painful experiences can promote cooperation within social groups. In Experiments 1 and 2, we induced pain by asking some participants to insert their hands in ice water and to perform leg squats. In Experiment 3, we induced pain by asking some participants to eat a hot chili pepper. Participants performed these tasks in small groups. We found evidence for a causal link: Sharing painful experiences with other people, compared with a no-pain control treatment, promoted trusting interpersonal relationships by increasing perceived bonding among strangers (Experiment 1) and increased cooperation in an economic game (Experiments 2 and 3). Our findings shed light on the social effects of pain, demonstrating that shared pain may be an important trigger for group formation. © The Author(s) 2014.

    Objective To examine whether pain sensitivity and pain catastrophizing are associated with persistent pain and disability after lumbar spine surgery. Design Prospective observational cohort study. Setting Academic medical center. Participants Patients (N = 68, mean ± SD age = 57.9 ± 13.1 years, N female = 40 (58.8%)) undergoing spine surgery for a degenerative condition from March 1, 2012 to April 30, 2013 were assessed 6 weeks, 3 months, and 6 months after surgery. Interventions Not applicable. Main Outcome Measure(s) The main outcome measures were persistent back pain intensity, pain interference, and disability. Patients with persistent back pain intensity, pain interference, or disability were identified as those patients reporting Brief Pain Inventory scores ≥ 4 and Oswestry Disability Index scores ≥ 21 at all postoperative time points. Results From 6 weeks to 6 months after surgery, approximately 12.9%, 24.2%, and 46.8% of patients reported persistent back pain intensity, pain interference, or disability, respectively. Increased pain sensitivity at 6 weeks was associated with having persistent back pain intensity (OR = 2.0, 95% CI = 1.0; 4.1) after surgery. Increased pain catastrophizing at 6 weeks was associated with having persistent back pain intensity (OR = 1.1, 95% CI = 1.0; 1.2), pain interference (OR = 1.1, 95% CI = 1.0; 1.2), and disability (OR = 1.3, 95% CI = 1.1; 1.4). An interaction effect was not found between pain sensitivity and pain catastrophizing on persistent outcomes (p > 0.05). Conclusion(s) Findings suggest the importance of early postoperative screening for pain sensitivity and pain catastrophizing in order to identify patients at-risk for poor postoperative pain intensity, interference, and/or disability outcomes. Future research should consider the benefit of targeted therapeutic strategies for patients with these postoperative prognostic factors. PMID:26101845

    Healthy humans can be divided into the pain adaptive (PA) and the pain nonadaptive (PNA) groups; PA showed a greater decrease in pain rating to a cold pressor test (CPT) than PNA. This study examined if the dichotomy of pain adaptability existed in individuals with chronic musculoskeletal pain. CPTs at 2°C and 7°C were used to assess the status of pain adaptability in participants with either chronic nonspecific low back pain or knee osteoarthritis. The participants' potency of conditioned pain modulation (CPM) and local inhibition were measured. The strengths of pain adaptability at both CPTs were highly correlated. PA and PNA did not differ in their demographic characteristics, pain thresholds from thermal and pressure stimuli, or potency of local inhibition or CPM. PA reached their maximum pain faster than PNA (t 41 = -2.76, P adaptability exists in musculoskeletal pain patients. Consistent with the healthy human study, the strength of pain adaptability and potency of CPM are not related. Pain adaptability could be another form of endogenous pain inhibition of which clinical implication is yet to be understood. The dichotomy of pain adaptability was identified in healthy humans. The current study confirms that this dichotomy also exists in individuals with chronic musculoskeletal pain, and could be reliably assessed with CPTs at 2°C and 7°C. Similar to the healthy human study, pain adaptability is not associated with CPM, and may reflect the temporal aspect of pain inhibition. Copyright © 2018 The American Pain Society.

    Full Text Available The seabob shrimp (Xiphopenaeus kroyeri represents an important fishing resource for artisanal fishermen in coastal areas of southern Brazil. Stock assessments of this species ha ve generally relied on biomass dynamics models as applied to CPUE time-series, which (a are only available for a small offshore fraction of the exploited population and (b does not comprise patterns of the shallowest artisanal fishing grounds. This work explores the use of extensive catch and effort data derived from a small-scale trawl fishery to obtain swept-area estimates of abundance and removal rates in a limited coastal area of southern Brazil (Tijucas Bay, Santa Catarina State, 27°15'S-48°33'W. Data were obtained from 7,198 fishing trips monitored at the fishing communities between June 2004 and August 2005. Because three parameters of the swept-area equation (i.e. trawl velocity, catch efficiency and wing spread were unknown, they were defined through a stochastic procedure and calibrated by estimates produced by a Leslie depletion model applied to concurrent catches obtained in one fishing ground. A 21.7% removal rate was estimated for the period June 2004-January 2005; this increased to nearly 34% between February and July 2005. This removal scenario predicted that a five-month fishery would suffice to remo ve 90% of the biomass available in the Tijucas Bay, nearing the 87% CPUE reduction observed in the same period. Whereas abundance and harvest rate estimates were likely affected by inadequate knowledge of the swept-area equation parameters, the similarity of these estimates with relative abundance indexes supports the convenience of the proposed method and justifies future efforts to improve its accuracy.El camarón (Xiphopenaeus kroyeri representa un importante recurso para pescadores artesanales en areas costeras del sur de Brasil.

  16. Cannabinoids and Pain

    Directory of Open Access Journals (Sweden)

    J Michael Walker

    2001-01-01

    Full Text Available Cannabinoids have been used to treat pain for many centuries. However, only during the past several decades have rigorous scientific methods been applied to understand the mechanisms of cannabinoid action. Cannabinoid receptors were discovered in the late 1980s and have been found to mediate the effects of cannabinoids on the nervous system. Several endocannabinoids were subsequently identified. Many studies of cannabinoid analgesia in animals during the past century showed that cannabinoids block all types of pain studied. These effects were found to be due to the suppression of spinal and thalamic nociceptive neurons, independent of any actions on the motor systems. Spinal, supraspinal and peripheral sites of cannabinoid analgesia have been identified. Endocannabinoids are released upon electrical stimulation of the periaqueductal gray, and in response to inflammation in the extremities. These observations and others thus suggest that a natural function of cannabinoid receptors and their endogenous ligands is to regulate pain sensitivity. The therapeutic potential of cannabinoids remains an important topic for future investigations, with previous work suggesting utility in clinical studies of cancer and surgical pain. New modes of delivery and/or new compounds lacking the psychotropic properties of the standard cannabinoid ligands offer promise for cannabinoid therapeutics for pain.

    Neugebauer, Volker

    2015-01-01

    A limbic brain area the amygdala plays a key role in emotional responses and affective states and disorders such as learned fear, anxiety and depression. The amygdala has also emerged as an important brain center for the emotional-affective dimension of pain and for pain modulation. Hyperactivity in the laterocapsular division of the central nucleus of the amygdala (CeLC, also termed the “nociceptive amygdala”) accounts for pain-related emotional responses and anxiety-like behavior. Abnormally enhanced output from the CeLC is the consequence of an imbalance between excitatory and inhibitory mechanisms. Impaired inhibitory control mediated by a cluster of GABAergic interneurons in the intercalated cell masses (ITC) allows the development of glutamate- and neuropeptide-driven synaptic plasticity of excitatory inputs from the brainstem (parabrachial area) and from the lateral-basolateral amygdala network (LA-BLA, site of integration of polymodal sensory information). BLA hyperactivity also generates abnormally enhanced feedforward inhibition of principal cells in the medial prefrontal cortex (mPFC), a limbic cortical area that is strongly interconnected with the amygdala. Pain-related mPFC deactivation results in cognitive deficits and failure to engage cortically driven ITC-mediated inhibitory control of amygdala processing. Impaired cortical control allows the uncontrolled persistence of amygdala pain mechanisms. PMID:25846623

    Full Text Available Background: Pain context plays a significant role in the perception of pain. Despite recent interest in vicarious learning and anxiety in pain modulation, there have been no attempts to explore pain modulation by specific environmental cues. Aims: Therefore, the present study evaluated pain responses in the condition that was attributed as either anxiety relevant (AR or anxiety irrelevant. Materials and Methods: Participants were exposed to both conditions through social observational learning. Pain perception was assessed by means of a visual analog scale ranging from 0 = no pain to 10 = maximum imaginable pain. State anxiety, empathy, expectancy, and desire for pain relief were also measured at both neutral and emotionally inducing conditions. Results: No effect of relevancy of anxiety for the pain context on any of the pain-related constructs was found. However, participants in the AR condition reported an increased desire for pain relief. Maximizing similarities between observed and experienced pain context did not enhance observational learning effects in the emotionally inducing condition regardless of its relevance, but significant changes were found in comparison to the affectively neutral group. Conclusions: These results could have potentially significant clinical implications suggesting that even though observing painful procedures does not increase pain it could affect medication usage.

    Chronic pain is prevalent among older adults but is underrecognized and undertreated. The approach to pain assessment and management in older adults requires an understanding of the physiology of aging, validated assessment tools, and common pain presentations among older adults. To identify the overall principles of pain management in older adults with a specific focus on common painful conditions and approaches to pharmacologic treatment. We searched PubMed for common pain presentations in older adults with heart failure, end-stage renal disease, dementia, frailty, and cancer. We also reviewed guidelines for pain management. Our review encompassed 2 guidelines, 10 original studies, and 22 review articles published from 2000 to the present. This review does not discuss nonpharmacologic treatments of pain. Clinical guidelines support the use of opioids in persistent nonmalignant pain. Opioids should be used in patients with moderate or severe pain or pain not otherwise controlled but with careful attention to potential toxic effects and half-life. In addition, clinical practice guidelines recommend use of oral nonsteroidal anti-inflammatory drugs with extreme caution and for defined, limited periods. An understanding of the basics of pain pathophysiology, assessment, pharmacologic management, and a familiarity with common pain presentations will allow clinicians to effectively manage pain for older adults. © 2013 Elsevier HS Journals, Inc.

    Chronic pain after surgery occurs in 10-40% of individuals, including 5-20% of women after cesarean delivery in previous reports. Pain and depression 2 months after childbirth are independently associated with more severe acute post-delivery pain. Here we examine other predictors of pain at 2 months and determine the incidence of pain at 6 and 12 months after childbirth. Following Institutional Review Board approval, 1228 women were interviewed within 36 h of delivery. Of these, 937 (76%) were successfully contacted by telephone at 2 months, and, if they had pain, at 6 and 12 months after delivery. The primary outcome measure was presence of pain which began at the time of delivery. We also generated a model of severity of acute post-delivery pain and 2 month pain and depression. Pain which began at the time of delivery was remarkably rare 6 and 12 months later (1.8% and 0.3% [upper 95% confidence limit, 1.2%], respectively). Past history of pain and degree of tissue damage at delivery accounted for 7.0% and 16.7%, respectively, of one aspect in the variability in acute post-delivery pain. Neither of these factors was associated with incidence of pain 2 months later. Using a definition of new onset pain from delivery, we show a remarkably low incidence of pain 1 yr after childbirth, including those with surgical delivery. Additionally, degree of tissue trauma and history of chronic pain, risk factors for pain 2 months after other surgery, were unimportant to pain 2 months after cesarean or vaginal delivery.

    Historically, assessment of acute right upper quadrant abdominal pain has been a considerable clinical challenge. While clinical findings and laboratory data frequently narrow the differential diagnosis, symptom overlap generally precludes definitive diagnosis among the various diseases causing acute right upper quadrant pain. Fortunately, the advent of newer diagnostic imaging modalities has greatly improved the rapidity and reliability of diagnosis in these patients. An additional challenge to the physician, with increased awareness of the importance of cost effectiveness in medicine, is to select appropriate diagnostic schema that rapidly establish accurate diagnoses in the most economical fashion possible. The dual goals of this discussion are to assess not only the accuracy of techniques used to evaluate patients with acute right upper quadrant pain, but also to seek out cost-effective, coordinated imaging techniques to achieve this goal

    Full Text Available This issue of '19' has been guest edited by Louise Hide, Joanna Bourke, and Carmen Mangion. Collectively, we comprise the Birkbeck Pain Project, a three-year Wellcome Trust funded project that is led by Joanna Bourke. We are particularly interested in understanding how the meaning of pain - for sufferers, physicians, and other witnesses - changed over time. In this issue, articles by social and cultural historians, as well as literary scholars, examine and analyse the implications of shifting discourses in personal narratives as well as in religious communities, and in philosophical, medical, and psychiatric texts. By analysing language within current theories of the time, we can deepen our understanding of the complex interaction between the body, mind, and culture to gain insights into the ever-changing subjective experience of pain.

    Full Text Available For over 30 years, the International Association for the Study of Pain has defined pain as «an unpleasant sensorial and emotional experience associated to real or potential tissue damage». Today, evident shortcomings still exist in the use of adequate analgesia, especially in the emergency medicine context: pain is the most common symptom amongst the Emergency Department patients (reaching a prevalence of over 60%, however, statistics reported in literature show that only 45% of patients receive analgesic prescriptions on discharge. In recent years, the influence of changes connected to accreditation standards has generated new expectations of healthcare professionals; although this aspect connected to the evolution of public health provides a stimulus to the evolution of the practical aspect of everyday clinical work, we must not forget that doctors take the Hippocratic oath, the ethical obligation to treat suffering and pain, which is especially pertinent to doctors working in Emergency conditions. The quality of the service provided with regard to pain-relief in ED cannot exclude an analysis of the local situation, the definition of roles, the extrinsication of potential with the ultimate aim of providing a service as close as possible to user hopes. Organisational efforts must be directed at reaching excellent quality levels, in which the monitoring of the activities performed takes place through the registration and periodic re-evaluation of the deriving data. Through this observational, prospective study, we intend to evaluate the effective prevalence of the pain symptom in the Emergency Department and the impact of the use of different classes of analgesia, also estimating the latency between the onset of the symptom and triage in order to quantify the efficacy of the analgesia practiced.

    Full Text Available BACKGROUND Pain management in Polytrauma is a poorly-addressed concern at the time of active resuscitation. But, very often, pain assessment is also a challenge! Opioids belong to conventional analgesics of choice in any acute pain conditions. But, recently application of regional anaesthesia techniques and subanaesthetic doses of ketamine are satisfactorily employed. A clear understanding of neuropathic element of pain must be made as they require specific therapy. It must be emphasised that effective pain therapy is a multidisciplinary team work with active involvement of pain psychologist.

    This review includes a summary of contemporary theories of pain processing and advocates a multimodal analgesia approach for providing perioperative care. A summary of various medication classes and anesthetic techniques is provided that highlights evidence emerging from neurosurgical literature. This summary covers opioid management, acetaminophen, nonsteroidal antiinflammatories, ketamine, lidocaine, dexmedetomidine, corticosteroids, gabapentin, and regional anesthesia for neurosurgery. At present, there is not enough investigation into these areas to describe best practices for treating or preventing chronic pain in neurosurgery; but providers can identify a wider range of options available to personalize perioperative care strategies.

    Several anticonvulsant drugs are used in the management of neuropathic pain. Oxcarbazepine is an anticonvulsant drug closely related to carbamazepine. Oxcarbazepine has been reported to be efficacious in the treatment of neuropathic pain, but evidence from randomised controlled trials (RCTs) is conflicting. Oxcarbazepine is reportedly better tolerated than carbamazepine. This is the first update of a review published in 2013. To assess the benefits and harms of oxcarbazepine for different types of neuropathic pain. On 21 November 2016, we searched the Cochrane Neuromuscular Specialised Register, CENTRAL, MEDLINE and Embase. We searched the Chinese Biomedical Retrieval System (January 1978 to November 2016). We searched the US National Institutes of Health (NIH) databases and the World Health Organization (WHO) International Clinical Trials Registry Platform for ongoing trials in January 2017, and we wrote to the companies who make oxcarbazepine and to pain experts requesting additional information. All RCTs and randomised cross-over studies of oxcarbazepine for the treatment of people of any age or sex with any neuropathic pain were eligible. We planned to include trials of oxcarbazepine compared with placebo or any other intervention with a treatment duration of at least six weeks, regardless of administration route and dose. We used standard methodological procedures expected by Cochrane. Five multicentre, randomised, placebo-controlled, double-blind trials with a total of 862 participants were eligible for inclusion in this updated review. Three trials involved participants with painful diabetic peripheral neuropathy (DPN) (n = 634), one included people with neuropathic pain due to radiculopathy (n = 145), and one, which was newly identified at this update, involved participants with peripheral neuropathic pain of mixed origin (polyneuropathy, peripheral nerve injury or postherpetic neuralgia) (n = 83). Some studies did not report all outcomes of interest. For

Therefore the plan becomes an element of forecast that requires of substantial technical progressive adjustments, which are prevented and anyway not admitted from the present normative. Therefore is suggested a modification of the Law that currently is checking and governing all the jobs of consolidation and recovery of the environmental wealth. The preservation and recovery of environmental wealth constitute, behind any doubt, a culture of management of the natural capital to transmit to the future generations. In this respects, environmental and architectural wealth, having no economic value, and being thus wealth of public property, are most easily subject to the risk of deterioration. The preservation of environmental wealth (both natural and man-made) together with their aesthetic value, is linked to the preservation of the fundamental resources of a territory, such as water, the agricultural soil, the ore materials, etc. The economy and the economical development of many countries in the World, for example Egypt and Israel, but also Italy, and southern Italy (notably Calabria) in particular depend upon the correct use of this cultural and environmental wealth. For this reason there is nowadays in Italy a critical re-evaluation of the criteria to manage the preservation and recovery of environmental wealth. However, it must be stressed here that for a correct management of the environment, the technical aspects must be adequately substained by appropriate laws and rules.

    Navratilova, Edita; Porreca, Frank

    2015-01-01

    Pain is fundamentally unpleasant, a feature that protects the organism by promoting motivation and learning. Relief of aversive states, including pain, is rewarding. The aversiveness of pain, as well as the reward from relief of pain, is encoded by brain reward/motivational mesocorticolimbic circuitry. In this Review, we describe current knowledge of the impact of acute and chronic pain on reward/motivation circuits gained from preclinical models and from human neuroimaging. We highlight emerging clinical evidence suggesting that anatomical and functional changes in these circuits contribute to the transition from acute to chronic pain. We propose that assessing activity in these conserved circuits can offer new outcome measures for preclinical evaluation of analgesic efficacy to improve translation and speed drug discovery. We further suggest that targeting reward/motivation circuits may provide a path for normalizing the consequences of chronic pain to the brain, surpassing symptomatic management to promote recovery from chronic pain.

    Pain and Christianity appear to belong together: Christ's pain stands at the centre of God's healing; his pain leads to the salvation of mankind. We can learn from Jesus' example how to bear suffering and pain. In early Christian times, the belief that Jesus Christ suffered pain on the cross was usually not accepted. In line with the "apathy axiom", freedom from emotion was something to strive for at that time. Only after the acceptance of Christianity as the state religion of the Roman Empire in 380 AD did the pain of Christ again stand in the centre of the Christian doctrine of salvation. The memory of the fact that Jesus himself had to undergo the worst pain can still help people to overcome their pain and comfort them.

    Low back pain is highly prevalent and places a considerable burden on individuals, their families and communities. This back pain burden is unequally distributed around the world and within populations. Clinicians and researchers addressing back pain should be aware of the cultural, social and political context of back pain patients and how this context can influence pain perception, disability and health care use. Culture, which influences the beliefs and behaviour of individuals within a social group, could be considered an important contributor to the unequal distribution of back pain. However, there is paucity of high-quality research exploring the influence of culture on the experience and management of back pain. Further development and testing of specific tools, assessment methods and communication strategies are needed to improve our understanding of how cultural practices, values and identifications affect those dealing with back pain.

    The literature demonstrating sex differences in pain is sizable. Most explanations for these differences have focused on biologic mechanisms, and only a few studies have examined social learning. The purpose of this study was to examine the contribution of gender-role stereotypes to sex differences in pain. This study used experimental manipulation of gender-role expectations for men and women. One hundred twenty students participated in the cold pressor task. Before the pain task, participants were given 1 of 3 instructional sets: no expectation, 30-second performance expectation, or a 90-second performance expectation. Pain ratings, threshold, and tolerance were recorded. Significant sex differences in the "no expectation" condition for pain tolerance (t = 2.32, df = 38, P differ in their pain tolerance, pain threshold, or pain ratings. This is the first empirical study to show that manipulation of expectations alters sex differences in laboratory pain.

    Pain is physiologically classified as nociceptive pain, neuropathic pain, and psychogenic pain. Nociceptive pain is further divided into visceral pain, somatic pain, and referred pain. Visceral pain is dull, and it is difficult to locate the origin of such pain. Somatic pain is sharp, severe, and well localized. On receiving visceral input for pain, it affects somatic nerve inputting to the same spinal segments, then referred pain is felt in the skin and muscles supplied by it. Referred pain is felt in an area that is located at a distance from its cause. History taking is the most important factor for determining the cause of pain. Generally, all the necessary information regarding pain can be acquired if pain-related history is obtained using the "OPQRST" mnemonic, that is, onset, provocation/palliative factor, quality, region/radiation/related symptoms, severity, and time characteristics.

    Women are more affected than men by many chronic pain conditions, suggesting the effect of sex-related mechanisms in their occurrence. The role of gonadal hormones has been studied but with contrasting results depending on the pain syndrome, reproductive status, and hormone considered. The aim of the present study was to evaluate the pain changes related to the menopausal transition period. In this observational study, postmenopausal women were asked to evaluate the presence of pain in their life during the premenopausal and postmenopausal periods and its modification with menopause. One hundred one women were enrolled and completed questionnaires on their sociodemographic status, pain characteristics, and evolution. The most common pain syndromes were headache (38%), osteoarticular pain (31%), and cervical/lumbar pain (21%). Pain was present before menopause in 66 women, ceased with menopause in 17, and started after menopause in 18. Data were used for cluster analysis, which allowed the division of participants into four groups. In the first, all women experienced headaches that disappeared or improved with menopause. The second group included osteoarticular pain; the pain improved in half of these women and remained stable in the other half. The third group had cervical/lumbar pain, which disappeared or improved with menopause in all. The fourth group presented different kinds of moderate pain, which worsened in all. The present study provides preliminary data suggesting that menopause can affect pain depending on the painful condition experienced by the woman. This underlines the different interactions of menopause-related events with body structures involved in pain.

Methods: The seven-item version of painDETECT provides an overall score that targets only sensory symptoms, while the nine-item version adds responses on two items to the overall score, covering pain course pattern and pain radiation. Both versions have relevance in terms of characterizing broad NeP. The nine- and seven-item versions of painDETECT were administered to subjects with confirmed NeP across six conditions identified during office visits to US community-based physicians. Responses on the sensory symptom items were dichotomized into “at least moderate” (ie, moderate, strongly, very strongly relative to the combined other responses (never, hardly noticed, slightly. Logistic regression of dichotomized variables on the total painDETECT score provided probabilities of experiencing each symptom across the range of painDETECT scores. Results: Both painDETECT versions discriminated among the symptoms with similar probabilities across the score ranges. Using these data, the probability of moderately experiencing each pain sensory item was estimated for a particular score, providing a pain profile. Additionally, the likelihood of experiencing each sensation was determined for a discrete increase in score, ie, the odds of at least a moderate sensation of burning (versus less than a moderate sensation was 1.29 for a 1-point increase, 3.52 for a 5-point increase, and 12.42 for every 10-point increase in the nine-item painDETECT score

    2012-04-01

    Pain is a serious health care problem and there is growing evidence to support the use of hypnosis and cognitive-behavioral interventions for pain management. This article reviews clinical techniques and methods of cognitive hypnotherapy for pain management. Current research with emphasis given to randomized, controlled trials is presented and the efficacy of hypnotherapy for pain management is discussed. Evidence for cognitive hypnotherapy in the treatment in chronic pain, cancer, osteoarthritis, sickle cell disease, temporomandibular disorder, fibromyalgia, non-cardiac chest pain, and disability related chronic pains are identified. Implications for clinical practice and research are discussed in light of the accumulating evidence in support of the efficacy and effectiveness of cognitive hypnotherapy for pain management.

    2016-08-01

    Patients from different cultures, particularly from family-oriented societies, such as the Near and Middle East, southern Italy and Greece, have a different perception of pain and other healing expectations, even in contact with doctors, than for example patients in western societies. This aspect is not sufficiently taken into consideration by modern multimodal therapy approaches. The pain experienced is not limited to one part of the body but needs to be seen holistically in relation to the whole body. The limited access of patients to psychological complaints often leads to chronic pain or other physical complaints. For therapy and the therapist-patient relationship, it is essential to understand the significance of the pain experienced in the construction and experience of interpersonal relationships. The diseased body is an expression of the social, collective, economic, migrational history, mental and cultural state of mind of the patient; therefore, in the treatment of patients from traditional cultures a multimodal, interdisciplinary and culturally sensitive approach is necessary for effective pain treatment.

    Patellofemoral pain (PFP) is a frequent cause of anterior knee pain in athletes, which affects patients with and without structural patellofemoral joint (PFJ) damage. Most younger patients do not have any structural changes to the PFJ, such as an increased Q angle and a cartilage damage. This clinical entity is known as patellofemoral pain syndrome (PFPS). Older patients usually present with signs of patellofemoral osteoarthritis (PFOA). A key factor in PFPS development is dynamic valgus of the lower extremity, which leads to lateral patellar maltracking. Causes of dynamic valgus include weak hip muscles and rearfoot eversion with pes pronatus valgus. These factors can also be observed in patients with PFOA. The available evidence suggests that patients with PFP are best managed with a tailored, multimodal, nonoperative treatment program that includes short-term pain relief with nonsteroidal anti-inflammatory drugs (NSAIDs), passive correction of patellar maltracking with medially directed tape or braces, correction of the dynamic valgus with exercise programs that target the muscles of the lower extremity, hip, and trunk, and the use of foot orthoses in patients with additional foot abnormalities.

  2. Pain and microcrystalline arthritis

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available Microcrystals are responsible for some of the most common and complex arthropathies which are often accompanied by intense, severe pain and inflammatory reactions. The main pathogens are crystals of monosodium urate (MSU, responsible for the gout, calcium pyrophosphate (CPP, which deposits also in various clinical forms of arthopathies, and basic calcium phosphate associated with osteoarthritis. In this context, the microcrystal arthritis is characterized by multiple, acute attacks followed by chronic pain, disability, impaired quality of life, and increased mortality. Given their chronic nature, they represent an ever more urgent public health problem. MSU and CPP crystals are also able to activate nociceptors. The pain in mycrocrystalline arthritis (MCA is an expression of the inflammatory process. In the course of these diseases there is an abundant release of inflammatory molecules, including prostaglandins 2 and kinins. Interleukin-1 represents the most important cytokine released during the crystal-induced inflammatory process. Therefore, clinically, pain is the most important component of MCA, which lead to functional impairment and disability in a large proportion of the population. It is fundamental to diagnose these diseases as early as possible, and to this aim, to identify appropriate and specific targets for a timely therapeutic intervention.

  11. Pain and consciousness.

    Science.gov (United States)

    Garcia-Larrea, Luis; Bastuji, Hélène

    2017-10-12

    The aversive experience we call "pain" results from the coordinated activation of multiple brain areas, commonly described as a "pain matrix". This is not a fixed arrangement of structures but rather a fluid system composed of several interacting networks: A 'nociceptive matrix' includes regions receiving input from ascending nociceptive systems, and ensures the bodily characteristics of physical pain. A further set of structures receiving secondary input supports the 'salience' attributes of noxious stimuli, triggers top-down cognitive controls, and -most importantly- ensures the passage from pre-conscious nociception to conscious pain. Expectations and beliefs can still modulate the conscious experience via activity in supramodal regions with widespread cortical projections such as the ventral tegmental area. Intracortical EEG responses in humans show that nociceptive cortical processing is initiated in parallel in sensory, motor and limbic areas; it progresses rapidly to the recruitment of anterior insular and fronto-parietal networks, and finally to the activation of perigenual, posterior cingulate and hippocampal structures. Functional connectivity between sensory and high-level networks increases during the first second post-stimulus, which may be determinant for access to consciousness. A model is described, progressing from unconscious sensori-motor and limbic processing of spinothalamic and spino-parabrachial input, to an immediate sense of awareness supported by coordinated activity in sensorimotor and fronto-parieto-insular networks, and leading to full declarative consciousness through integration with autobiographical memories and self-awareness, involving posterior cingulate and medial temporal areas. This complete sequence is only present during full vigilance states. We contend, however, that even in unconscious subjects, repeated limbic and vegetative activation by painful stimuli via spino-amygdalar pathways can generate implicit memory traces and

    Full Text Available Objective. To compare Visual Analogue Scale (VAS scores with overall postoperative pain medication requirements including cumulative dose and patterns of medication utilization and to determine whether VAS scores predict pain medication utilization. Methods. VAS scores and pain medication data were collected from participants in a randomized trial of the utility of phenazopyridine for improved pain control following gynecologic surgery. Results. The mean age of the 219 participants was 54 (range19 to 94. We did not detect any association between VAS and pain medication utilization for patient-controlled anesthesia (PCA or RN administered (intravenous or oral medications. We also did not detect any association between the number of VAS scores recorded and mean pain scores. Conclusion. Postoperative VAS scores do not predict pain medication use in catheterized women inpatients following gynecologic surgery. Increased pain severity, as reflected by higher VAS scores, is not associated with an increase in pain assessment. Our findings suggest that VAS scores are of limited utility for optimal pain control. Alternative or complimentary methods may improve pain management.

  18. Biobehavioral pain profile in individuals with chronic spine pain.

    Science.gov (United States)

    Matteliano, Deborah; Scherer, Yvonne Krall; Chang, Yu-Ping

    2014-03-01

    Pain in the spine is the most frequently described pain problem in primary care, afflicting at least 54 million Americans. When spinal pain becomes chronic, the prognosis for recovery is poor, often leading to disability and reduced quality of life. Clinical treatment is inadequate, often focusing on physical pathology alone. To improve treatment outcomes for chronic pain as recommended by current guidelines, the Biobehavioral Pain Profile (BPP), which includes six pain response subscales, was developed to guide cognitive behavioral therapy (CBT). The purpose of this study was to describe the BPP in 100 individuals with chronic spine pain and examine the associations between the BPP and important clinical outcomes, including chronic pain, disability, and quality of life. Participants reported a high level of pain, a low quality of life, and a high level of disability despite receiving treatment with opioids. Scores on BPP subscales including evaluating loss of control, past and current experience, physiologic responsivity, and thoughts of disease progression were elevated, indicating a need for CBT. Five of the six BPP subscales had a significant association with quality of life, chronic pain, and disability with the thought of disease progression being a strong factor for most of the clinical outcome variables. By identifying BPP, clinicians can provide appropriate treatments to improve individuals' quality of life and prevent further disability. Further study using the BPP to guide CBT is needed.

  19. The Mysterious Southern Torque

    McDowell, M. S.

    2004-05-01

    Something weird happened to twist the southern hemisphere out of alignment with the northern, as evidenced by the positions of the mountain ranges of North and South America, the Atlantic MAR, and the closure of West Africa to North America - all smooth were the torque reversed. What happened, and when, and why? We identify a number of global "cracks" of almost exactly the same length and direction, with some, even more peculiarly, turning the same angle, and proceeding an equal distance in the new direction. The Emperor-Hawaiian chain, the Louisville chain and the west coast of North America, as examples, are essentially parallel. Their northerly legs follow the angle of the axis of orbital ellipse. But then they all make equal 45 degree easterly bends, to 17.5 NW, and continue on, still parallel, for very similar distances. It is the same at the north coast of South America, and the mid-section of the MAR from 46W to 12W. It is the distance from the Cameroons to Kenya, from the south end of the Red Sea to the SE Indian Ridge at the Nema Fracture zone, from west to east of the Nazca plate.What is all this? Coincidence? Seeing things? Researchers have attributed plate motion or hot spot motion or both or absolutely none, to all of the above. Geophysicists have dated the surfaces from Archean to Pleistocene by all possible scientific means, certainly no possible correlation can be made. Yet we postulate the physical reality can be demonstrated. It is so global a phenomenon that it is well beyond what a hot spot or a plate could do. Even a really tremendous impact would have trouble making such precise geometric arrangements. So what is it - perhaps the angle of rotation, or the inertia of northern hemisphere mass above the geoid? And if so, then, what changed it? It would seem that some huge imbalance occurred. Suppose the whole bottom blew out of the southern hemisphere, and the center of mass drastically altered. Suppose some unknown universal force changed our

  20. Alexithymic trait, painful heat stimulation and everyday pain experience

    Directory of Open Access Journals (Sweden)

    Olga ePollatos

    2015-10-01

    Full Text Available Background: Alexithymia was found to be associated with a variety of somatic complaints including somatoform pain symptoms. This study addressed the question of whether the different facets of alexithymia are related to responses in heat pain stimulation and its interrelations with levels of everyday pain as assessed by self report. Methods: In the study, sensitivity to heat pain was assessed in fifty healthy female participants. Alexithymia facets were assessed by the Toronto Alexithymia Scale. Pain threshold and tolerance were determined using a testing the limits procedure. Participants furthermore rated subjective intensities and unpleasantness of tonic heat stimuli (45.5 C to 47.5 C on visual analogue scales and on a questionnaire. Possible confounding with temperature sensitivity and mood was controlled. Everyday pain was assessed by self-report addressing everyday pain frequency, intensity and impairment experienced over the last two months. Results: Main results were that the facets of alexithymia were differentially associated with pain perception. The affective scale difficulties in describing feelings was associated with hyposensitivity to pain as indicated by higher pain tolerance scores. Furthermore, everyday pain frequency was related to increased alexithymia values on the affective scale difficulties in identifying feelings, whereas higher values on the cognitive alexithymia scale externally oriented thinking were related to lower pain impairment and intensity. Conclusions: We conclude that the different facets of alexithymia are related to alternations in pain processing. Further research on clinical samples is necessary to elucidate whether different aspects of alexithymia act as vulnerability factor for the development of pain symptoms.

    The development of studies on neuroimaging applied to hypnosis and to the study of pain not only helps to validate the existence of a hypnotic state but also to ratify its therapeutic effects. These studies also enable us to understand how hypnosis is effective on the cortical level.

    Full Text Available Although world-systems theory was originally formulated with our modern economic system in mind (Wallerstein 1974, it was not long before archaeologists began to apply it to ancient societies. Archaeologists and world-system theorists alike both argued that Wallerstein had disregarded evidence of interconnected, hierarchical systems in prehistoric times (Schneider 1977; Chase-Dunn & Hall 1991, 1997; Kardulias 1999a. Pailes and Whitecotton (1979 were among the first to modify world-systems theory for use in pre-capitalist settings. Since then many archaeologists have looked at data and regions with a world-systems perspective in mind (e.g. Champion 1989; Bilde et al. 1993; Rowlands & Larsen 1987; Kardulias 1999a. Some have attempted to map Wallerstein's theory directly onto prehistory (Kohl 1979; Whitecotton & Pailes 1986; Ekholm & Friedman 1982. Others have found the world systems model heuristically useful but lacking the analytical power needed for their prehistoric cases (Blanton et al. 1981; Upham 1982; Plog 1983; Alcock 1993. Building on the assumption that ancient societies were not qualitatively, but only quantitatively, different from modern capitalist ones (Schneider 1977; Sherratt & Sherratt 1991, this study applies world systems theory to the Southern Aegean during the Middle and Late Bronze Age (ca. 2000-1550 BC.

The nature of this pain cannot be well established on frequent occasions. The English-language medical literature currently classifies such disorders as greater trochanter pain syndrome (GTPS. Its major signs are chronic pain and local palpatory tenderness in the outer part of HJ. The development of GTPS may be associated with inflammation of the synovial bursae situated in the greater tronchanter, as well as with tendinitis, myorrhexis, iliotibial band syndrome, and other local changes in the adjacent tissues or with systemic diseases. So GTPS may be characterized as regional pain syndrome that frequently mimics pain induced by different diseases, including myofascial pain syndrome, osteoarthrosis, spinal diseases, etc.

    INTRODUCTION: Hospitalized children often describe needle-related procedures as the worst pain possible and such procedures may be emotionally traumatic. The use of hospital clowns related to painful medical procedures in children may offer pain relief, but this has not been systematically...... evaluated. The objective of this study was to assess the effect of a therapeutic clown in comparison to standard care on the experience of pain for children receiving venipuncture. METHODS: A sample of 116 children aged 4-15 years consecutively admitted to the hospital was allocated to either......: Without the clown present, the mean pain score (2.7±2.8) was not significantly different between the two age groups. Children aged 7-15 years had lower pain scores when the clown was present compared to the control group (P=0.025). Children aged 4-6 years had higher pain scores with the clown present...

    Disease whether it is acute, chronic, or at end stage, is all too regularly accompanied by pain. Pain is often difficult to control, in malignant disease in particular, even by using appropriate medications. Anesthesiologists and pain therapists have developed new invasive therapies including nerve block, sympatholysis, and neurolysis useful for both diagnosis and pain management. To insure the efficiency and safety of these procedures, and furthermore for elaborate techniques such as vertebroplasty, cementoplasty, and radio frequency bone ablation, imaging guidance becomes mandatory. This state-of-the-art book describes the techniques elaborated by interventional radiologists in the treatment and palliation of a variety of benign and malignant painful conditions. Each chapter written by an expert in the field concentrates on a particular aspect of pain management, with emphasis on practical issues. This book will serve as an invaluable source of information for the radiologist willing to learn about new pain therapy techniques aimed at optimizing or replacing more invasive traditional methods.

    Zadeh, Mahdi Hossein

    in the current study was to use exercise induced- muscle damage followed by ECC as an acute pain model and observe its effects on the sensitivity of the nociceptive system and blood supply in healthy subjects. Then, the effect of a repeated bout of the same exercise as a healthy pain relief strategy......Exercise-based pain management programs are suggested for relieving from musculoskeletal pain; however the pain experienced after unaccustomed, especially eccentric exercise (ECC) alters people´s ability to participate in therapeutic exercises. Subsequent muscle pain after ECC has been shown...... to cause localized pressure pain and hyperalgesia. A prior bout of ECC has been repeatedly reported to produce a protective adaptation known as repeated bout effect (RBE). One of the main scopes of the current project was to investigate the adaptations by which the RBE can be resulted from. The approach...

    The diagnosis and treatment of orofacial pain can be complex. The differential diagnosis is very extensive. Therefore, multidisciplinary diagnosis and treatment are often indicated. The diagnosis of chronic pain also entails the investigation of psychological factors. This is because psychological problems can play a role in the chronification of pain, but they can also be a consequence of chronic pain. Patients with persistent orofacial complaints should be seen by a medical team consisting of an oral and maxillofacial surgeon, a neurologist, an anaesthesiologist/pain specialist, a dentist-gnathologist, an orofacial physical therapist, and a psychologist or psychiatrist specialising in orofacial pain. Treatment options should be discussed, taking into account literature concerning their effectiveness. The general conclusion is that much research remains to be done into the causes of, and treatments for, orofacial pain.

    Inguinal herniotomy is one of the most frequent surgical procedures and chronic pain affecting everyday activities is reported in approximately 10% of patients. However, the neurophysiological changes and underlying pathophysiological mechanisms of postherniotomy pain are not known in detail...... postoperatively. A quantitative sensory testing protocol was used, assessing sensory dysfunction type, location and severity. We assessed the protocol test-retest variability using data from healthy control subjects. All patients (pain and pain-free) had signs of nerve damage, seen as sensory dysfunction......). The specific finding of reduced pain detection threshold over the external inguinal annulus is consistent with damage to the cutaneous innervation territory of nervous structures in the inguinal region. The correspondence between pain location and sensory disturbance suggests that the pain is neuropathic...

    This document deals with possible energy growth in Southern African countries. This region possesses substantial energy resources (including fossil fuels), but because of political instability, government intervention, financial paralysis and lack of adequate transportation infrastructure, this region faces problems in satisfying energy needs. Two key international actions, namely the South African Development Community (SADC) Energy Protocol and the Southern African Power Pool (SAPP) are expected to enhance energy trade and promote economic development.

  16. Craniofacial Pain: Brainstem Mechanisms

    Directory of Open Access Journals (Sweden)

    Barry J Sessle

    1996-01-01

    Full Text Available This article reviews recent research advances in animals that have identified critical neural elements in the brainstem receiving and transmitting craniofacial nociceptive inputs, as well as some of the mechanisms involved in the modulation and plasticity of nociceptive transmission. Nociceptive neurones in the trigeminal (V brainstem sensory nuclear complex can be classified as nociceptive-specific (NS or wide dynamic range (WDR. Some of these neurones respond exclusively to sensory inputs evoked by stimulation of facial skin or oral mucosa and have features suggesting that they are critical neural elements involved in the ability to localize an acute superficial pain and sense its intensity and duration. Many of the V brainstem nociceptive neurones, however, receive convergent inputs from afferents supplying deep craniofacial tissues (eg, dural vessel, muscle and skin or mucosa. These neurones are likely involved in deep pain, including headache, because few nociceptive neurones receive inputs exclusively from afferents supplying these tissues. These extensive convergent input patterns also appear to be important factors in pain spread and referral, and in central mechanisms underlying neuroplastic changes in V neuronal properties that may occur with injury and inflammation. For example, application of the small fibre excitant and inflammatory irritant mustard oil into the temporomandibular joint, masseter or tongue musculature induces a prolonged but reversible enhancement of responses to cutaneous and deep afferent inputs of most WDR and NS neurones. These effects may be accompanied by increased electromyographic activity reflexly induced in the masticatory muscles by mustard oil, and involve endogenous N-methyl-D-aspartate and opioid neurochemical mechanisms. Such peripherally induced modulation of brainstem nociceptive neuronal properties reflects the functional plasticity of the central V system, and may be involved in the development of

    Anterior knee pain is a common complain in all ages athletes. It may be caused by a large variety of injuries. There is a continuum of diagnoses and most of the disorders are closely related. Repeated minor trauma and overuse play an important role for the development of lesions in Hoffa's pad, extensor mechanism, lateral and medial restrain structures or cartilage surface, however usually an increase or change of activity is referred. Although the direct relation of cartilage lesions, especially chondral, and pain is a subject of debate these lesions may be responsible of early osteoarthrosis and can determine athlete's prognosis. The anatomy and biomechanics of patellofemoral joint is complex and symptoms are often unspecific. Transient patellar dislocation has MR distinct features that provide evidence of prior dislocation and rules our complication. However, anterior knee pain more often is related to overuse and repeated minor trauma. Patella and quadriceps tendon have been also implicated in anterior knee pain, as well as lateral or medial restraint structures and Hoffa's pad. US and MR are excellent tools for the diagnosis of superficial tendons, the advantage of MR is that permits to rule out other sources of intraarticular derangements. Due to the complex anatomy and biomechanic of patellofemoral joint maltracking is not fully understood; plain films and CT allow the study of malalignment, new CT and MR kinematic studies have promising results but further studies are needed. Our purpose here is to describe how imaging techniques can be helpful in precisely defining the origin of the patient's complaint and thus improve understanding and management of these injuries

    To date, pain perception is thought to be a creative process of modulation carried out by an interplay of pro- and anti-nociceptive mechanisms. Recent research demonstrates that pain experience constitutes the result of top-down processes represented in cortical descending pain modulation. Cortical, mainly medial and frontal areas, as well as subcortical structures such as the brain stem, medulla and thalamus seem to be key players in pain modulation. An imbalance of pro- and anti-nociceptive mechanisms are assumed to cause chronic pain disorders, which are associated with spontaneous pain perception without physiologic scaffolding or exaggerated cortical activation in response to pain exposure. In contrast to recent investigations, the aim of the present study was to elucidate cortical activation of somatoform pain disorder patients during baseline condition. Scalp EEG, quantitative Fourier-spectral analyses and LORETA were employed to compare patient group (N = 15) to age- and sex-matched controls (N = 15) at rest. SI, SII, ACC, SMA, PFC, PPC, insular, amygdale and hippocampus displayed significant spectral power reductions within the beta band range (12-30 Hz). These results suggest decreased cortical baseline arousal in somatoform pain disorder patients. We finally conclude that obtained results may point to an altered baseline activity, maybe characteristic for chronic somatoform pain disorder.

  20. [Management of neuropathic pain].

    2015-07-01

    Neuropathic pain is often underestimated and not adequately treated. The DN4 scale is very useful for its identification since it will benefit from pharmacological and non-pharmacological specific alternative care. The pathophysiological mechanisms involve the hyperexcitability of nociceptive pathways or decreased inhibitory descending controls that will be the target of pharmacological treatments. Frontline molecules are antidepressants (tricyclics and mixed serotonin and norepinephrine reuptake inhibitors) and antiepileptics (α2δ calcium channel inhibitors). However, these drugs will only have a partial efficacy on pain. The therapeutic strategy is based on reasonable goals, starting with a monotherapy adapted to the patient's symptoms and comorbidities and increased step by step. Patient compliance to contract is essential and requires clear and complete information. The impact on profession, social and family integration should rapidly be taken into account. In case of inefficiency, a change of the first-line treatment or an association could be considered. Some indications justify a specific therapy. Patients with resistant chronic pain should be sent to a specialized centre. New drugs are being studied and non-pharmacological support must be evaluated.
