    Full Text Available Introduction. Vibroacoustic disease (VAD is the whole-body pathology caused by excessive exposure to LFN. For the past 25 years, it has been know that low frequency noise (LFN, <500 Hz, including infrasound targets the respiratory system. In LFN-exposed rodents, the morphological changes of respiratory tract tissue partially explained some respiratory symptoms reported by VAD patients. However, many questions remain unanswered. Recently, some volunteer VAD patients underwent bronchoscopy in order to ascertain possible damage that could be associated with their respiratory complaints. Methods. Fourteen fully-informed and volunteer VAD patients were submitted to bronchoscopy, and biopsies were removed for analysis. Results. All patients exhibited small submucosal vascular-like lesions near the spurs, consisting of increased collagen and elastin fibres. Histology disclosed cilliary abnormalities, basal membrane hyperplasia, and thickening of vessel walls. In five patients, collagen bundles appeared degenerative and disrupted. No inflammatory process was ever identified, and no differences were seen between smokers and non-smokers. Discussion. Data is in accordance with what was observed in LFN-exposed animal models and also in 8 VAD patients who developed lung tumours. Collagen disruption and degeneration was also observed in electron microscopy images of the respiratory tract of LFN-exposed rodents. Thickened blood and lymphatic vessel walls have been consistently seen in images of VAD patients and of LFN-exposed rodents. During bronchoscopy performed by other reasons, this sort of structural aspects is not frequently seen. Taken together, it is strongly suggested that these findings could be VAD-specific.

    Full Text Available Background: Long-term low frequency noise exposure (LFN (≤ 500 Hz, including infrasound may lead to the development of vibroacoustic disease (VAD, a systemic pathology characterized by the abnormal growth of extra-cellular matrices. The respiratory system is a target for LFN. Fibrosis of the respiratory tract epithelia was observed in VAD patients through biopsy, and confirmed in animal models exposed to LFN. Voice acoustic analysis can detect vocal fold variations of mass, tension, muscular and neural activity. Frequency perturbation (jitter, amplitude perturbation (shimmer and harmonicto- noise ratio (HNR are used in the evaluation of the vocal function, and can be indicators of the presence and degree of severity of vocal pathology. Since the respiratory system is the energy source of the phonation process, this raises questions about the effects of VAD on voice production. The purpose of this study was to determine if voice acoustic parameters of VAD patients are different from normative data. Methods: Nine individuals (5 males and 4 females diagnosed with VAD were recorded performing spoken and sung tasks. The spoken tasks included sustaining vowels and fricatives. The sung tasks consisted of maximum phonational frequency range (MPFR. Voice acoustic parameters analysed were: fundamental frequency (F0, jitter, shimmer, HNR and temporal measures. Results: Compared with normative data, both males and females diagnosed with VAD exhibited increased F0, shimmer and HNR. Jitter, MPFR and one temporal measure were reduced. Conclusions: VAD individuals presented voice acoustic parameter differences in spectral, temporal and perturbation measures, which may be indicative of small morphological changes in the phonatory system.

    In recent years, claims have proliferated in cyberspace that wind turbines cause a large variety of symptoms and diseases. One of these, "vibroacoustic disease" (VAD) is frequently mentioned. The aim of this study is to examine the quality of the evidence on how VAD came to be associated with wind turbine exposure by wind farm opponents. Searches of the web (Google advanced) and major research databases for papers on VAD and wind turbines. Self-citation analysis of research papers on VAD. Google returned 24,700 hits for VAD and wind turbines. Thirty-five research papers on VAD were found, none reporting any association between VAD and wind turbines. Of the 35 papers, 34 had a first author from a single Portuguese research group. Seventy-four per cent of citations to these papers were self-citations by the group. Median self-citation rates in science are around 7%. Two unpublished case reports presented at conferences were found asserting that VAD was "irrefutably demonstrated" to be caused by wind turbines. The quality of these reports was abject. VAD has received virtually no scientific recognition beyond the group who coined and promoted the concept. There is no evidence of even rudimentary quality that vibroacoustic disease is associated with or caused by wind turbines. The claim that wind turbines cause VAD is a factoid that has gone 'viral' in cyberspace and may be contributing to nocebo effects among those living near turbines. © 2013 The Authors.

    Full Text Available The article deals with the vibroacoustical analysis of rail vehicle and is the extension of the previously presented work “Modelování podvozku kolejového vozidla s poddajným rámem”. The vibroacoustical analysis uses the outcomes of the dynamical analysis of rail vehicle bogie i.e. surface velocities of the bogie frame to compute the acoustic power radiated by the bogie frame and forces acting in the bogie-body interface. The radiated power and the force spectra are then used as the excitation to the rail body model in the environment Auto-SEA to compute the interior acoustic quantities.

    To accurately analyze vibroacoustics in MR head gradient coils. A detailed theoretical model for gradient coil vibroacoustics, including the first description and modeling of Lorentz damping, is introduced and implemented in a multiphysics software package. Numerical finite-element method simulations were used to establish a highly accurate vibroacoustic model in head gradient coils in detail, including the newly introduced Lorentz damping effect. Vibroacoustic coupling was examined through an additional modal analysis. Thorough experimental studies were used to validate simulations. Average experimental sound pressure levels (SPLs) and accelerations over the 0-3000 Hz frequency range were 97.6 dB, 98.7 dB, and 95.4 dB, as well as 20.6 g, 8.7 g, and 15.6 g for the X-, Y-, and Z-gradients, respectively. A reasonable agreement between simulations and measurements was achieved. Vibroacoustic coupling showed a coupled resonance at 2300 Hz for the Z-gradient that is responsible for a sharp peak and the highest SPL value in the acoustic spectrum. We have developed and used more realistic multiphysics simulation methods to gain novel insights into the underlying concepts for vibroacoustics in head gradient coils, which will permit improved analyses of existing gradient coils and novel SPL reduction strategies for future gradient coil designs.

    Because of the specific biomechanical environment of the patellofemoral joint, chondral disorders, including chondromalacia, often are observed in this articulation. Chondromalacia via pathologic changes in cartilage may lead to qualitative impairment of knee joint motion. To determine the patellofemoral joint motion quality in particular chondromalacia stages and to compare with controls. Retrospective, comparative study. Voivodship hospitals, university biomechanical laboratory. A total of 89 knees with chondromalacia (25 with stage I; 30 with stage II and 34 with stage III) from 50 patients and 64 control healthy knees (from 32 individuals). Vibroacoustic signal pattern analysis of joint motion quality. For all knees vibroacoustic signals were recorded. Each obtained signal was described by variation of mean square, mean range (R4), and power spectral density for frequency of 50-250 Hz (P1) and 250-450 Hz (P2) parameters. Differences between healthy controls and all chondromalacic knees as well as chondromalacia patellae groups were observed as an increase of analyzed parameters (P chondromalacia patellae was found. All chondromalacia groups were differentiated by the use of all analyzed parameters (P chondromalacia. Chondromalacia generates abnormal vibroacoustic signals, and there seems to be a relationship between the level of signal amplitude as well as frequency and cartilage destruction from the superficial layer to the subchondral bone.

  14. Energy Harvesting with Piezoelectric Element Using Vibroacoustic Coupling Phenomenon

    Directory of Open Access Journals (Sweden)

    Hiroyuki Moriyama

    2013-01-01

    Full Text Available This paper describes the vibroacoustic coupling between the structural vibrations and internal sound fields of thin structures. In this study, a cylindrical structure with thin end plates is subjected to the harmonic point force at one end plate or both end plates, and a natural frequency of the end plates is selected as the forcing frequency. The resulting vibroacoustic coupling is then analyzed theoretically and experimentally by considering the dynamic behavior of the plates and the acoustic characteristics of the internal sound field as a function of the cylinder length. The length and phase difference between the plate vibrations, which maximize the sound pressure level inside the cavity, are clarified theoretically. The theoretical results are validated experimentally through an excitation experiment using an experimental apparatus that emulates the analytical model. Moreover, the electricity generation experiment verifies that sufficient vibroacoustic coupling can be created for the adopted electricity generating system to be effective as an electric energy-harvesting device.

  15. Respiratory pathology in vibroacoustic disease: 25 years of research

    Directory of Open Access Journals (Sweden)

    Nuno A.A. Castelo Branco

    2007-01-01

    Full Text Available Background: Respiratory pathology induced by low frequency noise (LFN, <500 Hz, including infrasound is not a novel subject given that in the 1960's, within the context of U.S. and U.S.S.R. Space Programs, other authors have already reported its existence. Within the scope of vibroacoustic disease (VAD, a whole-body pathology caused by excessive exposure to LFN, respiratory pathology takes on specific features. Initially, respiratory pathology was not considered a consequence of LFN exposure; but today, LFN can be regarded as a major agent of disease that targets the respiratory system. The goal of this report is to put forth what is known to date on the clinical signs of respiratory pathology seen in VAD patients. Methods: Data from the past 25 years of research will be taken together and presented. Results: In persons exposed to LFN on the job, respiratory complaints appear after the first 4 years of professional activity. At this stage, they disappear during vacation periods or when the person is removed form his /her workstation for other reasons. With long-term exposure, more serious situations can arise, such as, atypical pleural effusion, respiratory insufficiency, fibrosis and tumours. There is no correlation with smoking habits. In LFN--exposed animal models, morphological changes of the pleura, and loss of the phagocytic ability of pleural mesothelial cells (explaining the atypical pleural effusions. Fibrotic lesions and neo-vascularization were observed along the entire respiratory tract. Fibrosis lesions and neovascularisation were observed throughout the respiratory tract of the animals seen. Pre-malignant lesions, metaplasia e displasia, were also identified. Discussion: LFN is an agent of disease and the respiratory tract is one of its preferential targets. The respiratory pathology associated with VAD needs further in-depth studies in order to achieve a greater understanding, and develop methods of pharmacological intervention

  16. Virtual microphone sensing through vibro-acoustic modelling and Kalman filtering

    van de Walle, A.; Naets, F.; Desmet, W.

    2018-05-01

    This work proposes a virtual microphone methodology which enables full field acoustic measurements for vibro-acoustic systems. The methodology employs a Kalman filtering framework in order to combine a reduced high-fidelity vibro-acoustic model with a structural excitation measurement and small set of real microphone measurements on the system under investigation. By employing model order reduction techniques, a high order finite element model can be converted in a much smaller model which preserves the desired accuracy and maintains the main physical properties of the original model. Due to the low order of the reduced-order model, it can be effectively employed in a Kalman filter. The proposed methodology is validated experimentally on a strongly coupled vibro-acoustic system. The virtual sensor vastly improves the accuracy with respect to regular forward simulation. The virtual sensor also allows to recreate the full sound field of the system, which is very difficult/impossible to do through classical measurements.

    Noise has various effects on comfort, performance and health of human. Sound are analysed by human brain based on the frequencies and amplitudes. In a dynamic system, transmission of sound and vibrations depend on frequency and direction of the input motion and characteristics of the output. It is imperative that automotive manufacturers invest a lot of effort and money to improve and enhance the vibro-acoustics performance of their products. The enhancement effort may be very difficult and time-consuming if one relies only on 'trial and error' method without prior knowledge about the sources itself. Complex noise inside a vehicle cabin originated from various sources and travel through many pathways. First stage of sound quality refinement is to find the source. It is vital for automotive engineers to identify the dominant noise sources such as engine noise, exhaust noise and noise due to vibration transmission inside of vehicle. The purpose of this paper is to find the vibro-acoustical sources of noise in a passenger vehicle compartment. The implementation of spectral analysis method is much faster than the 'trial and error' methods in which, parts should be separated to measure the transfer functions. Also by using spectral analysis method, signals can be recorded in real operational conditions which conduce to more consistent results. A multi-channel analyser is utilised to measure and record the vibro-acoustical signals. Computational algorithms are also employed to identify contribution of various sources towards the measured interior signal. These achievements can be utilised to detect, control and optimise interior noise performance of road transport vehicles.

    2001-02-01

    The importance of the launcher vibroacoustic environment is increasing with respect to satellite loads due to the increase in size and decrease in surface mass of lightweight appendages like antennas and solar arrays. The loads generated by the vibroacoustic environment need to be covered adequately to ensure satellite structural integrity. This is of particular importance in the low-frequency range where the low frequencies of light appendages and equipment couple with the acoustic environment. In order to cope with the increasing demand for prediction of structural loads due to the acoustic environment, various methods have been developed in the frame of ESA research and development activities. These range from simplified approaches with partial fluid-structure coupling, e.g. the POSTAR package provided by INTESPACE (France) to more sophisticated approaches with full fluid-structure coupling. In the frequency domain this includes pure finite element modelling techniques, where specific tools have been developed by FFA (Sweden) using the ASKA package, as well as coupled finite element—boundary element approaches that have been developed in cooperation with DASA-Dornier (Germany), STRACO (France) and FFA using the commercial packages ASKA and RAYON. For fully coupled fluid structure analysis in the time domain the ASTRYD code from METRAVIB (France) is employed where advancements have been supported by CNES. Applications of these tools range from simple benchmarks such as simply supported plates, cavity enclosures or generic satellite-fairing models to complex satellite structure configurations. Evaluations of antenna reflector structures (Artemis communication antenna) and satellite equipment panels (polar platform) are presented. The paper covers also the investigation of payload/fairing effects (influence of fairing helium purging on the coupled-system response) together with DASA-Dornier, FFA and STRACO, as well as the vibroacoustic analysis of solar array

    2013-02-01

    First book about the aeroacoustics of automotive turbochargers. Author of the book ''Rotordynamics of Automotive Turbochargers'', Springer, 2012. Written by an R and D expert in the turbocharger industry. Aero and Vibroacoustics of Automotive Turbochargers is a topic involving aspects from the working fields of thermodynamics of turbomachinery, aerodynamics, rotordynamics, and noise propagation computation. In this broadly interdisciplinary subject, thermodynamics of turbomachinery is used to design the turbocharger and to determine its operating conditions. Aerodynamics is needed to study the compressor flow dynamics and flow instabilities of rotating stall and surge, which can produce growling and whining-type noises. Rotordynamics is necessary to study rotor unbalance and self-excited oil-whirl instabilities, which lead to whistling and constant tone-type noises in rotating floating oil-film type bearings. For the special case of turbochargers using ball bearings, some high-order harmonic and wear noises also manifest in the rotor operating range. Lastly, noise propagation computation, based on Lighthill's analogy, is required to investigate airborne noises produced by turbochargers in passenger vehicles. The content of this book is intended for advanced undergraduates, graduates in mechanical engineering, research scientists and practicing engineers who want to better understand the interactions between these working fields and the resulting impact on the interesting topic of Aero and Vibroacoustics of Automotive Turbochargers.

    Cough monitoring is an important element of the diagnostics of respiratory diseases. The European Respiratory Society recommends objective assessment of cough episodes and the search for methods of automatic analysis to make obtaining the quantitative parameters possible. The cough "events" could be classified by a microphone and a sensor that measures the vibrations of the chest. Analysis of the recorded signals consists of calculating the features vectors for selected episodes and of performing automatic classification using them. The aim of the study was to assess the accuracy of classification based on an artificial neural networks using vibroacoustic signals collected from chest. Six healthy, young men and eight healthy, young women carried out an imitated cough, hand clapping, speech and shouting. Three methods of parametrization were used to prepare the vectors of episode features - time domain, time-frequency domain and spectral modeling. We obtained the accuracy of 95% using artificial neural networks.

    Science.gov (United States)

    Kassem, M.; Soize, C.; Gagliardini, L.

    2009-06-01

    In this paper, an energy-density field approach applied to the vibroacoustic analysis of complex industrial structures in the low- and medium-frequency ranges is presented. This approach uses a statistical computational model. The analyzed system consists of an automotive vehicle structure coupled with its internal acoustic cavity. The objective of this paper is to make use of the statistical properties of the frequency response functions of the vibroacoustic system observed from previous experimental and numerical work. The frequency response functions are expressed in terms of a dimensionless matrix which is estimated using the proposed energy approach. Using this dimensionless matrix, a simplified vibroacoustic model is proposed.

  7. Vibroacoustic Tailoring of a Rod-Stiffened Composite Fuselage Panel with Multidisciplinary Considerations

    Science.gov (United States)

    Allen, Albert R.; Przekop, Adam

    2015-01-01

    An efficient multi-objective design tailoring procedure seeking to improve the vibroacoustic performance of a fuselage panel while maintaining or reducing weight is presented. The structure considered is the pultruded rod stitched efficient unitized structure, a highly integrated composite structure concept designed for a noncylindrical, next-generation flight vehicle fuselage. Modifications to a baseline design are evaluated within a six-parameter design space including spacing, flange width, and web height for both frame and stringer substructure components. The change in sound power radiation attributed to a design change is predicted using finite-element models sized and meshed for analyses in the 500 Hz, 1 kHz, and 2 kHz octave bands. Three design studies are carried out in parallel while considering a diffuse acoustic field excitation and two types of turbulent boundary-layer excitation. Kriging surrogate models are used to reduce the computational costs of resolving the vibroacoustic and weight objective Pareto fronts. The resulting Pareto optimal designs are then evaluated under a static pressurization ultimate load to assess structural strength and stability. Results suggest that choosing alternative configurations within the considered design space can reduce weight and improve vibroacoustic performance without compromising strength and stability of the structure under the static load condition considered, but the tradeoffs are significantly influenced by the spatial characteristics of the assumed excitation field.

    2015-12-15

    The present study aimed at examining whether methodological strategies from a previously implemented study design could be transferred to the evaluation of the psychological and physiological effects of a music therapy intervention working with vibroacoustic stimulation in palliative care. Nine participants suffering from advanced cancer took part in single-sessions of music therapy, lasting for 30 min. The live music therapy intervention utilized singing chair sounds and vocal improvisation. Visual analogue scales (VAS) were used to assess self-ratings of pain, relaxation, and well-being before and after each session. During the intervention, we continuously recorded heart rate variability (HRV) as a measure of autonomic functioning. Data collection was complemented by a semi-structured interview to explore subjective experiences in more detail. Feasibility was defined as the ability to complete 80 % of the sessions in accordance with the study protocol. In 5 out of 9 sessions (55 %) it was possible to deliver the intervention and obtain all data as intended. VAS assessment was feasible, although graphical and statistical examination revealed only marginal mean changes between pre and post. HRV recordings were subject to artifacts. While HRV parameters differed between individuals, mean changes over time remained relatively constant. Interview data confirmed that the individual perception was very heterogeneous, ranging from "calming" to "overwhelming". The criterion of feasibility was not met in this study. Physiological data showed high attrition rates, most likely due to movement artifacts and reduced peripheral blood flow in some participants' extremities. Examination of individual-level trajectories revealed that vibroacoustic stimulation may have an impact on the autonomic response. However, the direction and mechanisms of effects needs to be further explored in future studies. German Clinical Trials Register - DRKS00006137 (July 4(th), 2014).

    2014-06-01

    The experimental reproduction of random pressure fields on a plane panel and corresponding induced vibrations is studied. An open-loop reproduction strategy is proposed that uses the synthetic array concept, for which a small array element is moved to create a large array by post-processing. Three possible approaches are suggested to define the complex amplitudes to be imposed to the reproduction sources distributed on a virtual plane facing the panel to be tested. Using a single acoustic monopole, a scanning laser vibrometer and a baffled simply supported aluminum panel, experimental vibroacoustic indicators such as the Transmission Loss for Diffuse Acoustic Field, high-speed subsonic and supersonic Turbulent Boundary Layer excitations are obtained. Comparisons with simulation results obtained using a commercial software show that the Transmission Loss estimation is possible under both excitations. Moreover and as a complement to frequency domain indicators, the vibroacoustic behavior of the panel can be studied in the wave number domain.

    Vibroacoustography (VA) is an imaging technology that utilizes the acoustic response of tissues to a localized, low frequency radiation force to generate a spatially resolved, high contrast image. Previous studies have demonstrated the utility of VA for tissue identification and margin delineation in cancer tissues. However, the relationship between specimen viscoelasticity and vibroacoustic emission remains to be fully quantified. This work utilizes the effects of variable acoustic wave profiles on unique tissue-mimicking phantoms (TMPs) to maximize VA signal power according to tissue mechanical properties, particularly elasticity. A micro-indentation method was utilized to provide measurements of the elastic modulus for each biological replica. An inverse relationship was found between elastic modulus (E) and VA signal amplitude among homogeneous TMPs. Additionally, the difference frequency (Δf ) required to reach maximum VA signal correlated with specimen elastic modulus. Peak signal diminished with increasing Δf among the polyvinyl alcohol specimen, suggesting an inefficient vibroacoustic response by the specimen beyond a threshold of resonant Δf. Comparison of these measurements may provide additional information to improve tissue modeling, system characterization, as well as insights into the unique tissue composition of tumors in head and neck cancer patients.

    Full Text Available In this work, a vibro-acoustic numerical and experimental analysis was carried out for the chain cover of a low powered four-cylinder four-stroke diesel engine, belonging to the FPT (FCA Power Train family called SDE (Small Diesel Engine. By applying a methodology used in the acoustic optimization of new FPT engine components, firstly a finite element model (FEM of the engine was defined, then a vibration analysis was performed for the whole engine (modal analysis, and finally a forced response analysis was developed for the only chain cover (separated from the overall engine. The boundary conditions applied to the chain cover were the accelerations experimentally measured by accelerometers located at the points of connection among chain cover, head cover, and crankcase. Subsequently, a boundary element (BE model of the only chain cover was realized to determine the chain cover noise emission, starting from the previously calculated structural vibrations. The numerical vibro-acoustic outcomes were compared with those experimentally observed, obtaining a good correlation. All the information thus obtained allowed the identification of those critical areas, in terms of noise generation, in which to undertake necessary improvements.

    2013-01-01

    Aero and Vibroacoustics of Automotive Turbochargers is a topic involving aspects from the working fields of thermodynamics of turbomachinery, aerodynamics, rotordynamics, and noise propagation computation.   In this broadly interdisciplinary subject, thermodynamics of turbomachinery is used to design the turbocharger and to determine its operating conditions.  Aerodynamics is needed to study the compressor flow dynamics and flow instabilities of rotating stall and surge, which can produce growling and whining-type noises. Rotordynamics is necessary to study rotor unbalance and self-excited oil-whirl instabilities, which lead to whistling and constant tone-type noises in rotating floating oil-film type bearings. For the special case of turbochargers using ball bearings, some high-order harmonic and wear noises also manifest in the rotor operating range. Lastly, noise propagation computation, based on Lighthill’s analogy, is required to investigate airborne noises produced by turbochargers in passenger vehi...

    2017-09-01

    Rail vehicles in interaction with a railway structure induce vibrations that are propagating to surrounding structures and cause noise disturbance in the surrounding areas. Since tram tracks in urban areas often share the running surface with road vehicles one of top priorities is to achieve low maintenance and long lasting structure. Research conducted in scope of this paper gives an overview of newly designed tram track structures designated for use on Zagreb tram network and their performance in terms of noise and vibration mitigation. Research has been conducted on a 150 m long test section consisted of three tram track types: standard tram track structure commonly used on tram lines in Zagreb, optimized tram structure for better noise and vibration mitigation and a slab track with double sleepers embedded in a concrete slab, which presents an entirely new approach of tram track construction in Zagreb. Track has been instrumented with acceleration sensors, strain gauges and revision shafts for inspection. Relative deformations give an insight into track structure dynamic load distribution through the exploitation period. Further the paper describes vibro-acoustic measurements conducted at the test site. To evaluate the track performance from the vibro-acoustical standpoint, detailed analysis of track decay rate has been analysed. Opposed to measurement technique using impact hammer for track decay rate measurements, newly developed measuring technique using vehicle pass by vibrations as a source of excitation has been proposed and analysed. Paper gives overview of the method, it’s benefits compared to standard method of track decay rate measurements and method evaluation based on noise measurements of the vehicle pass by.

    2018-01-01

    This paper deals with the state-of-the-art strategies and techniques based on vibro-acoustic signals that can monitor and diagnose malfunctions in Internal Combustion Engines (ICEs) under both test bench and vehicle operating conditions. Over recent years, several authors have summarized what is known in critical reviews mainly focused on reciprocating machines in general or on specific signal processing techniques: no attempts to deal with IC engine condition monitoring have been made. This paper first gives a brief summary of the generation of sound and vibration in ICEs in order to place further discussion on fault vibro-acoustic diagnosis in context. An overview of the monitoring and diagnostic techniques described in literature using both vibration and acoustic signals is also provided. Different faulty conditions are described which affect combustion, mechanics and the aerodynamics of ICEs. The importance of measuring acoustic signals, as opposed to vibration signals, is due since the former seem to be more suitable for implementation on on-board monitoring systems in view of their non-intrusive behaviour, capability in simultaneously capturing signatures from several mechanical components and because of the possibility of detecting faults affecting airborne transmission paths. In view of the recent needs of the industry to (-) optimize component structural durability adopting long-life cycles, (-) verify the engine final status at the end of the assembly line and (-) reduce the maintenance costs monitoring the ICE life during vehicle operations, monitoring and diagnosing system requests are continuously growing up. The present review can be considered a useful guideline for test engineers in understanding which types of fault can be diagnosed by using vibro-acoustic signals in sufficient time in both test bench and operating conditions and which transducer and signal processing technique (of which the essential background theory is here reported) could be

  2. A lightweight vibro-acoustic metamaterial demonstrator: Numerical and experimental investigation

    Science.gov (United States)

    Claeys, C.; Deckers, E.; Pluymers, B.; Desmet, W.

    2016-03-01

    In recent years metamaterials gained a lot of attention due to their superior noise and vibration insulation properties, be it at least in some targeted and tuneable frequency ranges, referred to as stopbands. These are frequency zones for which free wave propagation is prevented throughout the metamaterial, resulting in frequency zones of pronounced wave attenuation. Metamaterials are achieved due to addition of an, often periodic, grid of resonant structures to a host material or structure. The interaction between resonant inclusions and host structure can lead to a performance which is superior to the ones of any of the constituent materials. A key element in this concept is that waves can be affected by incorporating structural resonant elements of sub-wavelength sizes, i.e. features that are actually smaller than the wavelength of the waves to be affected. This paves the way towards compact and light vibro-acoustic solutions in the lower frequency ranges. This paper discusses the numerical design and experimental validation of acoustic insulation based on the concept of metamaterials: a hollow core periodic sandwich structure with added local resonant structures. In order to investigate the sensitivity to specific parameters in the metamaterial design and the robustness of the design, a set of variations on the nominal design are investigated. The stop bands are numerically predicted through unit cell modelling after which a full vibro-acoustic finite element model is applied to predict the insertion loss of the demonstrator. The results of these analyses are compared with measurements; both indicate that this metamaterials concept can be applied to combine light weight, compact volume and good acoustic behaviour.

    Full Text Available The residue in sunflower oil is a dispersed phase consisting of particulate products grinding sunflower seeds in the form of particles of the pulp, oil cake, meal, residual quantities of metals, pesticides. In the recycling process they are in the oil in suspension and negatively affect its quality. For research an experimental setup was developed allowing to change the angle of inclination of the filter element. The regularities of filtration were determined without preliminary purification of sunflower oil by centrifugation and after centrifugation. It is established, the contamination of centrifuged oil in the initial period is 14.6 times lower. After 10 minutes of treatment, it decreases by 62%, after 20 minutes – by 79.4%. With a 30-minute treatment, particles of 0.005-0.1 mm in size are removed to 90%, which is approximated to the refined oil in terms of contamination. The influence of vibration-acoustic action on sunflower oil during its filtration is shown. At the last stage of production, the peroxide index is reduced to 2-3 moles of active oxygen, and after 3 months of storage – from 11.8 to 7.7, which according to GOST corresponds to the highest-grade oil. The regularities of the filtration without pre-treatment of sunflower oil by centrifugation and after centrifugation. Shows the effect of vibroacoustic exposure on sunflower oil when filtering. The obtained data on the change of qualitative parameters of sunflower oil during its filtration in the field of vibroacoustic impact.

    While perceptual evaluation and sound quality testing with jury are now recognized as essential parts of acoustical product development, they are rarely implemented with spatial sound field reproduction. Instead, monophonic, stereophonic or binaural presentations are used. This paper investigates the workability and interest of a method to use complete vibroacoustic engineering models for auralization based on 2.5D Wave Field Synthesis (WFS). This method is proposed in order that spatial characteristics such as directivity patterns and direction-of-arrival are part of the reproduced sound field while preserving the model complete formulation that coherently combines frequency and spatial responses. Modifications to the standard 2.5D WFS operators are proposed for extended primary sources, affecting the reference line definition and compensating for out-of-plane elementary primary sources. Reported simulations and experiments of reproductions of two physically-accurate vibroacoustic models of thin plates show that the proposed method allows for an effective reproduction in the horizontal plane: Spatial and frequency domains features are recreated. Application of the method to the sound rendering of a virtual transmission loss measurement setup shows the potential of the method for use in virtual acoustical prototyping for jury testing.

    Full Text Available Currently used diagnostics systems are not always efficient and do not give straightforward results which allow for the assessment of the technological condition of the engine or for the identification of the possible damages in their early stages of development. Growing requirements concerning durability, reliability, reduction of costs to minimum and decrease of negative influence on the natural environment are the reasons why there is a need to acquire information about the technological condition of each of the elements of a vehicle during its exploitation. One of the possibilities to achieve information about technological condition of a vehicle are vibroacoustic phenomena. Symptoms of defects, achieved as a result of advanced methods of vibroacoustic signals processing can serve as models which can be used during construction of intelligent diagnostic system based on artificial neural networks. The work presents conception of use artificial neural networks in the task of combustion engines diagnosis.

    Full Text Available Background: The most frequently used test for evaluation of fetal health is the Non Stress Test (NST. Unfortunately it has a high incidence of false positive results. The combination of vibroacoustic stimulation with the NTS has been shown to reduce non reactive results. Methods: A tests assessment method was chosen with a simple randomized sampling. 40 pregnant women with non reactive NST in the first 20 minutes who received VAS in one of Tehran University's Hospitals were compared with BPP scores. A vibroacoustic stimulation was applied for a 3 seconds on the maternal abdomen and fallowed within 10 minutes.Data collection tools were NST, sonography instruments ,NST result paper, tooth brusher, watch, demographic questioner and check list. Data analysis was made by descriptive static and by using the Fisher's Exact Test (with level of significant at p<0/05. All statistical analysis were performed using an spss/win. Results: After VAS, 70% of non reactive tracing became reactive. All cases with fetal reactivity response after a VAS had a subsequent BPP score of 8 (negative predictive value of 100%. False positivity of VAS was lower than NST. Conclusion: VAS offers benefits, by decreasing the incidence of non reactive test and reducing test time. VAS lowers the rate of false positive NST. VAS is safe and allows more efficient of prenatal services. This test could be used as a rapid antepartum test to predict fetal well-being.

    1977-01-01

    Fundamental principles and possibilities of vibro-acoustic control of the primary coolant circuit in nuclear power plants for detecting failures (slack parts, penetration of foreign bodies, crack formation, etc.) are presented. As a result of pressure and flow rate fluctuations such failures give rise to characteristic changes in apmplitude and frequency of vibration and technological noise from the different aggregates with respect to a 'calibration' spectrum taken in the intact state. Nature and location of the failures may be determined by statistical analysis of the signals recorded from pressure and acceleration gauges. Certain parts of the primary circuit are controlled, especially the main circulation pumps. Additionally, neutron noise has been measured in order to control the core insertions. The method is illustrated by means of measurements performed in the units 1 to 4 of the Novovoronezh nuclear power plant during start-up operation and continuous operation. (author)

    2016-01-01

    The effect of stagger startup on the vibro-acoustic loads that form during the end- effects-regime of clustered rockets is studied using both full-scale (hot-gas) and laboratory scale (cold gas) data. Both configurations comprise three nozzles with thrust optimized parabolic contours that undergo free shock separated flow and restricted shock separated flow as well as an end-effects regime prior to flowing full. Acoustic pressure waveforms recorded at the base of the nozzle clusters are analyzed using various statistical metrics as well as time-frequency analysis. The findings reveal a significant reduction in end- effects-regime loads when engine ignition is staggered. However, regardless of stagger, both the skewness and kurtosis of the acoustic pressure time derivative elevate to the same levels during the end-effects-regime event thereby demonstrating the intermittence and impulsiveness of the acoustic waveforms that form during engine startup.

    Direct velocity feedback control of structures is well known to increase structural damping and thus reduce vibration. In multi-channel systems the way in which the velocity signals are used to inform the actuators ranges from decentralized control, through distributed or clustered control to fully centralized control. The objective of distributed controllers is to exploit the anticipated performance advantage of the centralized control while maintaining the scalability, ease of implementation, and robustness of decentralized control. However, and in seeming contradiction, some investigations have concluded that decentralized control performs as well as distributed and centralized control, while other results have indicated that distributed control has significant performance advantages over decentralized control. The purpose of this work is to explain this seeming contradiction in results, to explore the effectiveness of decentralized, distributed, and centralized vibro-acoustic control, and to expand the concept of distributed control to include the distribution of the optimization process and the cost function employed.

    Directory of Open Access Journals (Sweden)

    Shaogan Ye

    2017-01-01

    Full Text Available Low noise axial piston pumps become the rapid increasing demand in modern hydraulic fluid power systems. This paper proposes a systematic approach to simulate the vibroacoustic characteristics of an axial piston pump using a hybrid lumped parameters/finite element/boundary element (LP/FE/BE model, and large amount of experimental work was performed to validate the model. The LP model was developed to calculate the excitation forces and was validated by a comparison of outlet flow ripples. The FE model was developed to calculate the vibration of the pump, in which the modeling of main friction pairs using different spring elements was presented in detail, and the FE model was validated using experimental modal analysis and measured vibrations. The BE model was used to calculate the noise emitted from the pump, and a measurement of sound pressure level at representative field points in a hemianechoic chamber was conducted to validate the BE model. Comparisons between the simulated and measured results show that the developed LP/FE/BE model is effective in capturing the vibroacoustic characteristics of the pump. The presented approach can be extended to other types of fluid power components and contributes to the development of quieter fluid power systems.

    2018-01-01

    Full Text Available The verification of a space launcher at the design level is a complex issue because of (i the lack of a detailed modeling capability of the acoustic pressure produced by the rocket; and (ii the difficulties in applying deterministic methods to the large-scale metallic structures. In this paper, an innovative integrated design verification process is described, based on the bridging between a new semiempirical jet noise model and a hybrid finite-element method/statistical energy analysis (FEM/SEA approach for calculating the acceleration produced at the payload and equipment level within the structure, vibrating under the external acoustic forcing field. The result is a verification method allowing for accurate prediction of the vibroacoustics in the launcher interior, using limited computational resources and without resorting to computational fluid dynamics (CFD data. Some examples concerning the Vega-C launcher design are shown.

    Double-wall panels are known for their superior sound insulation properties over single wall panels as a sound barrier. The sound transmission phenomenon through a double-wall structure is a complex process involving vibroacoustic interaction between structural panels, the air-cushion in between, and the secondary acoustic domain. It is in this context a versatile and a fully coupled technique based on the finite-element-boundary element model is developed that enables estimation of sound transfer through a double-wall panel into an adjacent enclosure while satisfying the displacement compatibility across the interface. The contribution of individual components in the transmitted energy is identified through numerical simulations.

    2018-04-01

    The vibroacoustic study of the interaction of sound with a point-constrained, simply-supported square plate is considered in this paper. The plate is mounted flush on one of the walls of an infinite duct of rectangular cross section and is backed by a cavity. The plate response and the acoustic field is predicted by solving the coupled governing equations using modal expansion with the relevant eigenmodes of the plate dynamics and acoustic fields in the duct and cavity. By varying the location of the point constraint, the frequency characteristics of the transmission loss in the duct can be tuned. The point constraint can also alter the amplitude and spectral characteristics of the plate's response. Interestingly, some new peaks are observed in the response because of the excitation of unsymmetric modes which are otherwise dormant. Mode-localization phenomenon, which is the localization of vibration in specific regions of the plate, is observed for selected constrained points.

    2017-02-01

    This paper presents an analytical method for modeling the vibro-acoustic behavior of ribbed non-rectangular orthotropic clamped plates. To do this, the non-rectangular plate is embedded in an extended rectangular simply supported plate on which a spring distribution is added, blocking the extended part of the surface, and allowing the description of any inner surface shapes. The acoustical radiation of the embedded plate is ensured using the radiation impedances of the extended rectangular simply supported plate. This method is applied to an upright piano soundboard: a non-rectangular orthotropic plate ribbed in both directions by several straight stiffeners. A modal decomposition is adopted on the basis of the rectangular extended simply supported plate modes, making it possible to calculate the modes of a piano soundboard in the frequency range [0;3000] Hz, showing the different associated mode families. Likewise, the acoustical radiation is calculated using the radiation impedances of a simply supported baffled plate, demonstrating the influence of the string coupling point positions on the acoustic radiated power. The paper ends with the introduction of indicators taking into account spatial and spectral variations of the excitation depending on the notes, which add to the accuracy of the study from the musical standpoint. A parametrical study, which includes several variations of soundboard design, highlights the complexity of rendering high-pitched notes homogeneous.

    There is a need in research reactors like the one at INL to inspect irradiated materials and structures. The goal of this work is to develop a portable scanning infrastructure for a material characterization technique called vibro-acoustography (VA) that has been developed by the Idaho National laboratory for nuclear applications to characterize fuel, cladding materials, and structures. The proposed VA technology is based on ultrasound and acoustic waves; however, it provides information beyond what is available from the traditional ultrasound techniques and can expand the knowledge on nuclear material characterization and microstructure evolution. This paper will report on the development of a portable scanning system that will be set up to characterize materials and components in open water reactors and canals in situ. We will show some initial laboratory results of images generated by vibro-acoustics of surrogate fuel plates and graphite structures and discuss the design of the portable system.

    The paper discusses the use of wideband excitation in nonlinear vibro-acoustic modulation technique (VAM) used for damage detection. In its original form, two mono-harmonic signals (low and high frequency) are used for excitation. The low frequency excitation is typically selected based on a modal analysis test and high frequency excitation is selected arbitrarily in the ultrasonic frequency range. This paper presents a different approach with use of wideband excitation signals. The proposed approach gives the possibility to simplify the testing procedure by omitting the modal test used to determine the value of low frequency excitation. Simultaneous use of wideband excitation for high frequency solves the ambiguity related to the selection of the frequency of acoustic wave. Broadband excitation signals require, however, more elaborate signal processing methods to determine the intensity of modulation for a given bandwidth. The paper discusses the proposed approach and the related signal processing procedure. Experimental validation of the proposed technique is performed on a laminated composite plate with a barely visible impact damage that was generated in an impact test. Piezoceramic actuators are used for vibration excitation and a scanning laser vibrometer is used for noncontact data acquisition.

    Improvement of distinguishing criteria, determining defects of machinery and mechanisms, by vibroacoustic signals is a recent problem for technical diagnostics. The work objective is assessment of instantaneous values by methods of statistical decision making theory and risk of regulatory values of characteristic function modulus. The modulus of the characteristic function is determined given a fixed parameter of the characteristic function. It is possible to determine the limits of the modulus, which correspond to different machine’s condition. The data of the modulus values are used as diagnostic features in the vibration diagnostics and monitoring systems. Using such static decision-making methods as: minimum number of wrong decisions, maximum likelihood, minimax, Neumann-Pearson characteristic function modulus limits are determined, separating conditions of a diagnosed object.

    Regarding to GEN 4 context, it is necessary to fulfil the high safety standards for sodium fast reactors (SFR), particularly against water-sodium reaction which may occur in the steam generator units (SGU) in case of leak. This reaction can cause severe damages in the component in a short time. Detecting such a leak by visual in-sodium inspection is impossible because of sodium opacity. Hydrogen detection is then used but the time response of this method can be high in certain operating conditions. Active and passive acoustic leak detection methods were studied before SUPERPHENIX plant shutdown in 1997 to detect a water-into-sodium leak with a short time response. In the context of the new R and D studies for SFR, an innovative passive vibro-acoustic method is developed in the framework of a Ph.D. thesis to match with GEN 4 safety requirements. The method consists in assuming that a small leak emits spherical acoustic waves in a broadband frequency domain, which propagate in the liquid sodium and excite the SGU cylindrical shell. These spatially coherent waves are supposed to be buried by a spatially incoherent background noise. The radial velocities of the shell is measured by an array of accelerometers positioned on the external envelop of the SGU and a beam forming treatment is applied to increase the signal-to-noise ratio (SNR) and to detect and localize the acoustic source. Previous numerical experiments were achieved and promising results were obtained. In this paper, experimental results of the proposed passive vibro-acoustic leak detection are presented. The experiment consists in a cylindrical water-filled steel pipe representing a model of SGU shell without tube bundle. A hydro-phone emitting an acoustic signal is used to simulate an acoustic monopole. Spatially uncorrelated noise or water-flow induced shell vibrations are considered as the background noise. The beam-forming method is applied to vibration signals measured by a linear array of

    In this paper, a fully vibro-acoustic model for sound transmission across a multi-pane aircraft window is developed. The proposed model is efficiently applied for a set of window models to perform extensive theoretical parametric studies. The studied window configurations generally simulate the passenger window designs of modern aircraft classes which have an exterior multi-Plexiglas pane, an interior single acrylic glass pane and a dimmable glass ("smart" glass), all separated by thin air cavities. The sound transmission loss (STL) characteristics of three different models, triple-, quadruple- and quintuple-paned windows identical in size and surface density, are analyzed for improving the acoustic insulation performances. Typical results describing the influence of several system parameters, such as the thicknesses, number and spacing of the window panes, on the transmission loss are then investigated. In addition, a comparison study is carried out to evaluate the acoustic reduction capability of each window model. The STL results show that the higher frequencies sound transmission loss performance can be improved by increasing the number of window panels, however, the low frequency performance is decreased, particularly at the mass-spring resonances.

Since 1987, malignancy in VAD patients has been under close surveillance. To date, in a universe of 945 individuals, there are 46 cases of malignancies, of which 11 are multiple. Of the 11 cases of respiratory tract tumours, all were squamous cell carcinomas (SqCC. This report focuses on the morphological features of these tumours. Methods: Tumour fragments were collected (endoscopic biopsy or surgery from 11 male VAD patients (ave. age: 58±9 years, 3 non-smokers: 2 in glottis and 9 in the lung. In the 3 non-smokers, 2 had lung tumours and 1 had a glottis tumour. All were employed as or retired aircraft technicians, military or commercial pilots. Fragments were fixed either for light and electron microscopy. Immunohistochemistry studies used chromagranine and synaptophysine staining. Results: All lung tumours were located in the upper right lobe bronchi and were histologically poorly differentiated SqCC (Figs. 1, 2. The search with neuroendocrine markers was negative. The average age of tumour onset in helicopter pilots was below 50 years old while for the other professional groups it was above 50. Nine patients are deceased. The 2 surviving patients are heavy smokers (> 2 packs/day. Smoking habits had no i nfluence on tumour outcome and progression. Discussion: Epidemiological studies indicate that squamous cell carcinomas account for approximately 40% of all lung tumours in men. It seems to be highly relevant that all VAD patient respiratory tract tumours are squamous cell carcinomas. It is not surprising that helicopter pilots are

    Full Text Available Vibro-acoustic Transfer Path Analysis (TPA is a tool to evaluate the contribution of different energy propagation paths between a source and a receiver, linked to each other by a number of connections. TPA is typically used to quantify and rank the relative importance of these paths in a given frequency band, determining the most significant one to the receiver. Basically, two quantities have to be determined for TPA: the operational forces at each transfer path and the Frequency Response Functions (FRF of these paths. The FRF are obtained either experimentally or analytically, and the influence of the mechanical impedance of the source can be taken into account or not. The operational forces can be directly obtained from measurements using force transducers or indirectly estimated from auxiliary response measurements. Two methods to obtain the operational forces indirectly – the Complex Stiffness Method (CSM and the Matrix Inversion Method (MIM – associated with two possible configurations to determine the FRF – including and excluding the source impedance – are presented and discussed in this paper. The effect of weak and strong coupling among the paths is also commented considering the techniques previously presented. The main conclusion is that, with the source removed, CSM gives more accurate results. On the other hand, with the source present, MIM is preferable. In the latter case, CSM should be used only if there is a high impedance mismatch between the source and the receiver. Both methods are not affected by a higher or lower degree of coupling among the transfer paths.

    A nonlinear vibroacoustic absorber (Nonlinear Energy Sink: NES), involving a clamped thin membrane made in Latex, is assessed in the acoustic domain. This NES is here considered as an one-port acoustic system, analyzed at low frequencies and for increasing excitation levels. This dynamic and frequency range requires a suitable experimental technique, which is presented first. It involves a specific impedance tube able to deal with samples of sufficient size, and reaching high sound levels with a guaranteed linear response thank's to a specific acoustic source. The identification method presented here requires a single pressure measurement, and is calibrated from a set of known acoustic loads. The NES reflection coefficient is then estimated at increasing source levels, showing its strong level dependency. This is presented as a mean to understand energy dissipation. The results of the experimental tests are first compared to a nonlinear viscoelastic model of the membrane absorber. In a second step, a family of one degree of freedom models, treated as equivalent Helmholtz resonators is identified from the measurements, allowing a parametric description of the NES behavior over a wide range of levels.

    Celiac disease, an inflammatory disease of small bowel caused by sensitivity to dietary gluten and related protein, affects approximately 0.5-1% of the population in the Western world. Extra-intestinal symptoms and associated diseases are increasingly recognized including diabetes mellitus type 1, thyroid disease, dermatitis herpetiformis and ataxia. There have also been a number of reports of various types of renal involvement in patients with celiac disease including diabetes nephropathy, IgA nephropathy, membranous nephropathy, membranoproliferative glomerulonephritis, nephrotic syndrome related to malabsorption, oxalate nephropathy, and associations of celiac disease with chronic kidney disease and end-stage kidney disease. This review aims to present the current literature on possible pathologic mechanisms underlying renal disease in patients with celiac disease.

    There are a variety of dermatological diseases that are more commonly seen in patients with chronic kidney disease (CKD) and renal transplants than the general population. Directory of Open Access Journals (DOAJ), Google Scholar, Pubmed (NLM), LISTA (EBSCO) and Web of Science has been searched. Some cutaneous diseases are clearly unique to this population. Of them, Lindsay's Nails, xerosis cutis, dryness of the skin, nephrogenic systemic fibrosis and acquired perforating dermatosis have been described in chronic kidney disease patients. The most common malignancy found in all transplant recipients is non-melanoma skin cancer. It is important for patients and physicians to recognize the manifestations of skin disease in patients suffering from chronic kidney disease to mitigate the morbidity associated with these conditions.

    In this paper, sound radiation modes of baffled cylinders have been derived by constructing the radiation resistance matrix analytically. By examining the characteristics of sound radiation modes, it is found that radiation coefficient of each radiation mode increases gradually with the increase of frequency while modal shapes of sound radiation modes of cylindrical shells show a weak dependence upon frequency. Based on understandings on sound radiation modes, vibro-acoustics behaviors of cylindrical shells have been analyzed. The vibration responses of cylindrical shells are described by modified Fourier series expansions and solved by Rayleigh-Ritz method involving Flügge shell theory. Then radiation efficiency of a resonance has been determined by examining whether the vibration pattern is in correspondence with a sound radiation mode possessing great radiation efficiency. Furthermore, effects of thickness and boundary conditions on sound radiation of cylindrical shells have been investigated. It is found that radiation efficiency of thicker shells is greater than thinner shells while shells with a clamped boundary constraint radiate sound more efficiently than simply supported shells under thin shell assumption.

    Use of vibration and acoustic measurement is analyzed for detection of failures and wear assessment of gearheads of the KWB-3RDU shearer loaders with shearer drums on ranging arms. Problems associated with selecting the optimum measuring points on the gearheads as well as measuring methods and methods for statistical analysis of measurement results are analyzed. Amplitude and frequency range of vibrations generated by the elements of mechanical transmissions in the gearheads are investigated. Use of amplitude-spectrum discriminants for analyzing vibroacoustic processes during idle running and shearer drum operation under conditions of nominal loading is evaluated. Analyses showed that vibration and acoustic measurements are an efficienct method for wear assessment and forecasting service life of gearheads of the KWB-3RDU shearer loaders. The gearheads with the maximum vibrations were characterized by the lowest service life and the highest failure probability. Loading increase caused vibration increase under conditions of idle running and nominal loading. 13 references.

    It is well known that coeliac disease is associated with autoimmune endocrine diseases, such as autoimmune thyroid disease and insulin-dependent diabetes mellitus. Recently, coeliac disease has been shown in approximately 10% of patients with autoimmune Addison's disease. Addison's disease is the most common cause of primary adrenocortical insufficiency and it shares several clinical features with coeliac disease. Although hyperpigmentation and hypotension are the most specific signs, gastrointestinal symptoms are common and can be the first complaints of the patients. The aim of our study was to investigate the prevalence of coeliac disease in Italian patients with Addison's disease. Seventeen consecutive patients affected by Addison's disease (14 F, mean age 53.9 years, range 26-79 years) were enrolled in the study. Eleven of them were affected by Addison's disease associated with autoimmune thyroid disease and/or insulin-dependent diabetes mellitus; the other 6 patients were suffering from isolated Addison's disease. Diagnosis had been performed at the age of 40.5 years (range 23-55). Steroid treatment had already been started in 16 of the patients. Endomysial antibodies were tested in all of them and a duodenal biopsy was taken in those found to be positive for antiendomysial antibody (EMA). One out of 17 patients was found to be EMA positive. Duodenal biopsy confirmed the diagnosis of coeliac disease by showing subtotal villous atrophy. Although we studied only a small sample, our preliminary results confirmed that Addison's disease is associated with coeliac disease, being present in 5.9% of patients with Addison's disease. Since the symptoms can be similar and treatment of Addison's disease can mask coeliac disease, this association should always be actively investigated.

    Coronary artery disease is the cause of death in most patients who have transient ischemic attacks or stroke. Evaluation for this condition is not routinely performed in such patients, and no prospective studies have been reported. We prospectively examined 50 consecutive patients with transient ischemic attacks or mild stroke to determine the prevalence and importance of coronary artery disease. All patients were examined by a cardiologist and underwent both exercise thallium-201 scintigraphy and exercise radionuclide ventriculography. Sixteen patients were suspected to have coronary artery disease on the basis of clinical evaluation. In 15 of these the was confirmed by the nuclear scans. The remaining 34 patients had no clinical evidence of heart disease, yet 14 had abnormal cardiac scans. Twenty of 22 patients with abnormal scans who underwent cardiac catheterization had significant coronary artery disease or a cardiomyopathy. The discovery of heart disease altered clinical management in 13 patients. Overall, 29 of 50 patients had significant coronary artery disease, compared with a 7% prevalence of the condition in other patients of similar age at the same institution

    Periodontal disease is a chronic inflammatory gingival process that has been associated with the severity of respiratory diseases. In Mexico a prevalence of 78% was found in population with social security and > 60 years old. The aim of this study is to establish the association between periodontal disease and respiratory diseases according to the inpatient days. A cross-sectional study was conducted from January to December 2011. We included hospitalized patients, ≥ 18 years of age, without sedation or intubated. A dentist classified patients into two groups according to the severity of the periodontal disease: mild-to-moderate and severe. We estimated medians of inpatient days by disease and severity. Negative binomial models were adjusted to estimate incidence rate ratios and predicted inpatient days. 3,059 patients were enrolled. The median of observed and predicted inpatient days was higher in the group of severe periodontal disease (p disease, tuberculosis, and influenza had the highest incidence rates ratios of periodontal disease (p periodontal disease is positively -associated with inpatient days of patients with respiratory diseases.

    Full Text Available Both cystic fibrosis (CF and celiac disease can cause low bone mineral density (BMD and fractures. Celiac disease may occur at a higher frequency in patients with CF than the general population, and symptoms of these conditions may overlap. We report on two patients presenting with CF-related bone disease in the past year who were subsequently found to have concurrent celiac disease. Because adherence to a gluten-free diet may improve BMD in patients with celiac disease, this could have important implications for treatment. Clinicians should consider screening for celiac disease in patients with CF who have low BMD, worsening BMD in the absence of other risk factors, and/or difficult to treat vitamin D deficiency.

    Collagenous colitis (CC) is associated with autoimmune disorders. The aim of the present study was to investigate the relationship between CC and autoimmune disorders in a Swedish multicenter study. Patients with CC answered questionnaires about demographic data and disease activity. The patient's files were scrutinized for information about autoimmune diseases. A total number of 116 CC patients were included; 92 women, 24 men, median age 62 years (IQR 55-73). In total, 30.2% had one or more autoimmune disorder. Most common were celiac disease (CeD; 12.9%) and autoimmune thyroid disease (ATD, 10.3%), but they also had Sjögren's syndrome (3.4%), diabetes mellitus (1.7%) and conditions in skin and joints (6.0%). Patients with associated autoimmune disease had more often nocturnal stools. The majority of the patients with associated CeD or ATD got these diagnoses before the colitis diagnosis. Autoimmune disorders occurred in one-third of these patients, especially CeD. In classic inflammatory bowel disease (IBD), liver disease is described in contrast to CC where no cases occurred. Instead, CeD was prevalent, a condition not reported in classic IBD. Patients with an associated autoimmune disease had more symptoms. Patients with CC and CeD had an earlier onset of their colitis. The majority of the patients with both CC and CeD were smokers. Associated autoimmune disease should be contemplated in the follow-up of these patients.

    Objective: The prevalence of peripheral vascular disease (PVD) in patients with coronary artery disease (CAD) has been investigated in many different ways. It depends on the diagnostic methods used and definition of atherosclerotic manifestations in the different vascular beds. This study was carried out to determine the prevalence of PVD in the lower limbs in group of patients with CAD. Design: This is a prospective observational study. Place and duration of study: The study was conducted at Combined Military Hospital/Armed Forces institute of Cardiology, Rawalpindi, over a period of one year (January 1998 to January 1999). Subjects and methods: A total number of 200 patient (171 male and 29 females) aged 55-77 years with CAD. Diagnosed by coronary angiography were included in the study. In all patients blood pressure was recorded in both arms by sphygmomanometer and ankle systolic pressure by Doppler ultrasound. Ankle branchial index was calculated. Demographic data were obtained from the patient's hospital files. Results: The prevalence of PVD was 22.5% in patients with CAD in agreement with the results of most previous investigation. There was tendency towards increasing prevalence of PVD with more advanced CAD. Thirty patients (27%) showed evidence of triple vessel disease as compared to 13 patient (18%) with double vessel and 2 patients (1%) with single vessel disease. Conclusion: A non-invasive investigation of peripheral arterial circulation should be included early in the clinical consideration of patients with chest pain or similar symptoms suggesting coronary artery disease. Ankle systolic pressure appears to be simple and cheap technique for evaluation of results. (author)

    2015-12-01

    Full Text Available Determination of dependable diagnostic thresholds for tribologic signals received e.g. from antifriction bearings (in particular for insufficient number of measurements, only 4÷5 is a really difficult task due to complexity of working environment where such bearings are operated. Typical working environment for such objects must take account for operation time under various working conditions and accompanying (and disturbing signals, e.g. vibroacoustic ones. The sought assessment of the relationship between diagnostic signals and environmental noise can be determined from convolution of both diagnostic and environments signals that make up the complete set of received information. The convolution of these two series of signals can be obtained from an algorithm based on the Cauchy product. Then one has to find the coherence factor and the square of amplitude gain for the set of diagnostic signals with reference to various sets of signals received from environment, which makes it possible to evaluate cohesion of the investigated series of signals, thus their suitability to determine diagnostic threshold for tribologic signals intended for the analysis.

    This paper presents modeling and design of an active structural acoustic control (ASAC) system for controlling the low frequency sound field transmitted through an aircraft cabin window. The system uses stacked piezoelectric elements arranged in a manner to generate out-of-plane actuation point forces acting on the window panel boundaries. A theoretical vibro-acoustic model for an active quadruple-panel system is developed to characterize the dynamic behavior of the system and achieve a good understanding of the active control performance and the physical phenomena of the sound transmission loss (STL) characteristics. The quadruple-panel system represents the passenger window design used in some classes of modern aircraft with an exterior double pane of Plexiglas, an interior dust cover pane and a glazed dimmable pane, all separated by thin air cavities. The STL characteristics of identical pane window configurations with different piezoelectric actuator sets are analyzed. A parametric study describes the influence of important active parameters, such as the input voltage, number and location of the actuator elements, on the STL is investigated. In addition, a mathematical model for obtaining the optimal input voltage is developed to improve the acoustic attenuation capability of the control system. In general, the achieved results indicate that the proposed ASAC design offers a considerable improvement in the passive sound loss performance of cabin window design without significant effects, such as weight increase, on the original design. Also, the results show that the acoustic control of the active model with piezoelectric actuators bonded to the dust cover pane generates high structural vibrations in the radiating panel (dust cover) and an increase in sound power radiation. High active acoustic attenuation can be achieved by designing the ASAC system to apply active control forces on the inner Plexiglas panel or dimmable panel by installing the actuators on the

    Objective: To evaluate patients suffering from Hodgkin's disease to identify its epidemiological characteristics, modalities of treatment and features of survival. Place and Duration of Study: The study was conducted between July 1997 to June 1999 at the Oncology Department of Jinnah Hospital, Lahore. Subjects and Methods: A total 75 patient with Hodgkin's disease underwent Cotswold staging classification, complete hematological, renal and hepatic profile, LDH and uric acid. Chest radiograph abdominal and pelvic ultrasonography and CT scan/MRI bone marrow biopsies. All the patients received combination chemotherapy. Patients with bulky disease received field radiation. Results: Median age was eight ( 18 years). Male to female ratio was 3.5:1, advanced disease accounted for 68%, mixed cellularity was documented in 61% of patients. Eighty-two percent of patients belonged to lower socioeconomic strata. Forty-six patients (65.4%) achieved complete remission (CR) Major toxicities were hematological with febrile neutropenia in 14.6% patients. OS of patients achieving CR with good socioeconomic status was superior compared to patients with lower socioeconomic status (p<0.02). Treatment delays were due to economic constraints, illiteracy, malnutrition and co-morbid conditions. Conclusion: Advanced disease, mixed cellularity and male predominance was common. Socioeconomic status had a significant impact on the presentation of the disease. Poor tolerance to chemotherapy and enhanced toxicities are especially seen in the low socioeconomic group. (author)

    A computerized data bank system was developed for utilization of large amounts of vibration and acoustic data to formulate component random vibration design and test criteria. This system consists of a computer, graphics tablet, and a dry-silver hard copier which are all desk-top type hardware and occupy minimal space. The data bank contains data from the Saturn V and Titan III flight and static test programs. The vibration and acoustic data are stored in the form of power spectral density and one-third octave band plots over the frequency range from 20 to 2000 Hz. The data was stored by digitizing each spectral plot by tracing with the graphics tablet. The digitized data was statistically analyzed and the resulting 97.5% probability levels were stored on tape along with the appropriate structural parameters. Standard extrapolation procedures were programmed for prediction of component random vibration test criteria for new launch vehicle and payload configurations. This automated vibroacoustic data bank system greatly enhances the speed and accuracy of formulating vibration test criteria. In the future, the data bank will be expanded to include all data acquired from the space shuttle flight test program.

    Many countries, like Denmark, have tailored Disease Management Programs (DMPs) based on patients having single chronic diseases [defined institutionally as "program diseases" (PDs)], which can complicate treatment for those with multiple chronic diseases. The aims of this study were (a) to assess...... the prevalence and overlap among acutely hospitalized older medical patients of PDs defined by the DMPs, and (b) to examine transitions between different departments during hospitalization and mortality and readmission within two time intervals among patients with the different PDs. We conducted a registry study...... of 4649 acutely hospitalized medical patients ≥65 years admitted to Copenhagen University Hospital, Hvidovre, Denmark, in 2012, and divided patients into six PD groups (type 2 diabetes, chronic obstructive pulmonary disease, cardiovascular disease, musculoskeletal disease, dementia and cancer), each...

    A recent technological revolution in the fields of integrated MEMS has finally rendered possible the mechanical integration of active smart materials, electronics and power supply systems for the next generation of smart composite structures. Using a bi-dimensional array of electromechanical transducers, composed by piezo-patches connected to a synthetic negative capacitance, it is possible to modify the dynamics of the underlying structure. In this study, we present an application of the Floquet-Bloch theorem for vibroacoustic power flow optimization, by means of distributed shunted piezoelectric material. In the context of periodically distributed damped 2D mechanical systems, this numerical approach allows one to compute the multi-modal waves dispersion curves into the entire first Brillouin zone. This approach also permits optimization of the piezoelectric shunting electrical impedance, which controls energy diffusion into the proposed semi-active distributed set of cells. Furthermore, we present experimental evidence that proves the effectiveness of the proposed control method. The experiment requires a rectangular metallic plate equipped with seventy-five piezo-patches, controlled independently by electronic circuits. More specifically, the out-of-plane displacements and the averaged kinetic energy of the controlled plate are compared in two different cases (open-circuit and controlled circuit). The resulting data clearly show how this proposed technique is able to damp and selectively reflect the incident waves.

    Patients with autoimmune thyroid diseases (ATD) such as Graves' disease (GD) and Hashimoto thyroiditis (HT) may have non-organ specific autoantibodies such as ANA (antinuclear antibodies) and RF (rheumatoid factor). To study the prevalence of rheumatic autoantibodies in a group of ATD patients without known rheumatic diseases and to evaluate its association with the patients' epidemiological and treatment profile. To follow positive non-organ specific autoantibody-positive ATD individuals to investigate whether they will develop a rheumatic disorder. A sample of 154 ATD patients (70 HT and 84 GD; mean age 45.3 ± 14.2) had determination of ANA by immunofluorescence, using hep-2 cells as substrate, extractable nuclear antigen (ENA) profile by ELISA kits and RF by latex agglutination. Epidemiological and treatment profile were obtained through chart review. These patients were followed for the mean period of five years, between 2010 to 2015. Positive ANA was found in 17.5% (27/154) of the patients: anti-Ro/SS-A in 4/154 (2.5%); anti-RNP in 4/154 (2.5%) and anti-La/SS-B in 3/154 (1.9%). None had anti-Sm antibodies. RF was detected in 12/154 (7.7%) of ATD patients and was more common in older individuals (p = 0.007). There was a positive association between the presence of RF and ANA (p = 0.03; OR = 3.89; 95% CI = 1.1-13.3). None of the patients with positive autoantibodies developed clinical rheumatic diseases during the period of observation. We found rheumatic autoantibodies in 17.5% of ATD patients without rheumatic diseases. None of them were associated with the appearance of clinical rheumatic disorder during the period of five years. ©2018The Author(s). Published by S. Karger AG, Basel.

    There is a lack of objective data on the symptoms characterizing disease activity among adults with congenital heart disease (ACHD). The purpose of this study was to elicit the most important symptoms from patients across the spectrum of ACHD and to examine whether reported symptoms were similar across the spectrum of ACHD as a foundation for creating a patient-reported outcome measure(s). We constructed a 39-item survey using input from physicians specializing in ACHD to assess the symptoms patients associate with disease activity. Patients (n=124) prospectively completed this survey, and the results were analyzed based on underlying anatomy and disease complexity. A confirmatory cohort of patients (n=40) was then recruited prospectively to confirm the validity of the initial data. When grouped based on underlying anatomy, significant differences in disease-related symptom rankings were found for only 6 of 39 symptoms. Six symptoms were identified which were of particular significance to patients, regardless of underlying anatomy. Patients with anatomy of great complexity experienced greater overall symptom severity than those with anatomy of low or moderate complexity, attributable exclusively to higher ranking of 5 symptoms. The second patient cohort had symptom experiences similar to those of the initial cohort, differing in only 5 of 39 symptoms. This study identified 6 symptoms relevant to patients across the spectrum of ACHD and remarkable homogeneity of patient experience, suggesting that a single disease-specific patient-reported outcome can be created for quality and outcome assessments. © 2016 American Heart Association, Inc.

  8. [Hypothyroidism in patients with heart disease].

    Science.gov (United States)

    Jiskra, Jan

    Hypothyroidism is frequently found in patients with heart disease. It is a risk factor for atherosclerosis and ischemic heart disease and has a direct negative effect on both the left and right ventricular functions (hypothyroidism-induced cardiomyopathy). The confirmed manifest hypothyroidism is always a reason for replacement therapy with levothyroxine; regarding patients with heart disease, we always begin treatment with a small dose and increase it gradually. The treatment of subclinical hypothyroidism in patients with heart disease is disputable and its benefits probably depend on age. At a higher age, the therapy-related risks often outweigh its benefits, so we make do with the target levels of the thyroid stimulating hormone being within the upper band of the normal range, or even slightly above it, rather than overdosing the patient. To summarize in a simplified way, the treatment of subclinical hypothyroidism in patients with heart disease is the most effective in younger individuals, mainly those aged below 65, while at a higher age > 80 years the risk usually outweighs the benefit.Key words: cardiovascular risk - hypothyroidism - ischemic heart disease - left ventricular dysfunction - right ventricular dysfunction - subclinical hypothyroidism - thyroid peroxidase antibodies.

  9. Mortality in patients with pituitary disease.

    Sherlock, Mark

    Pituitary disease is associated with increased mortality predominantly due to vascular disease. Control of cortisol secretion and GH hypersecretion (and cardiovascular risk factor reduction) is key in the reduction of mortality in patients with Cushing\\'s disease and acromegaly, retrospectively. For patients with acromegaly, the role of IGF-I is less clear-cut. Confounding pituitary hormone deficiencies such as gonadotropins and particularly ACTH deficiency (with higher doses of hydrocortisone replacement) may have a detrimental effect on outcome in patients with pituitary disease. Pituitary radiotherapy is a further factor that has been associated with increased mortality (particularly cerebrovascular). Although standardized mortality ratios in pituitary disease are falling due to improved treatment, mortality for many conditions are still elevated above that of the general population, and therefore further measures are needed. Craniopharyngioma patients have a particularly increased risk of mortality as a result of the tumor itself and treatment to control tumor growth; this is a key area for future research in order to optimize the outcome for these patients.

    Full Text Available Background and Design: Celiac disease is an immune-mediated enteropathy which develops as a result of exposure to gluten in food products in individuals with a genetic predisposition. Gastrointestinal and extra-gastrointestinal clinical findings can be seen in these patients. An increased frequence of autoimmune diseases has been reported in patients with celiac disease. Some dermatological diseases, such as dermatitis herpetiformis, vitiligo, psoriasis, alopecia areata and recurrent aphthous stomatitis have been reported to be more common among patients with celiac disease. However, there are no controlled studies on this subject. The aim of this study was to identify the mucocutaneous symptoms seen in celiac patients and to compare these findings with a control group. Materials and Methods: Forty-nine celiac patients and 54 age-and sex-matched healthy volunteers were included in the study. In the patient group, celiac disease history, height and weight parameters, the medications of the patients, compliance to a gluten-free diet, concomitant skin disorders and additional illnesses were questioned; height and weight parameters, diagnosed illnesses, and medications were questioned in the control group. Dermatological analyses were performed in all participants. Results: Mucocutaneous findings were found to be present in 38 patients (77.6% in the celiac patient group and in 31 (57.4% individuals in the control group. The presence of mucocutaneous findings in celiac patients was significantly more common than in the control group. While immune-mediated mucocutaneous diseases were detected in 8 celiac patients (16.3%, none of the individuals in the control group had immune-mediated mucocutaneous diseases and a statistically significant difference was found between the two groups. Conclusion: In celiac patients, the frequency of immune-mediated mucocutaneous diseases and all mucocutaneous diseases were found to be increased. Therefore, we suggest

  11. Experimental investigation of the influence of internal frames on the vibroacoustic behavior of a stiffened cylindrical shell using wavenumber analysis

    The understanding of the influence of non-axisymmetric internal frames on the vibroacoustic behavior of a stiffened cylindrical shell is of high interest for the naval or aeronautic industries. Several numerical studies have shown that the non-axisymmetric internal frame can increase the radiation efficiency significantly in the case of a mechanical point force. However, less attention has been paid to the experimental verification of this statement. That is why this paper proposes to compare the radiation efficiency estimated experimentally for a stiffened cylindrical shell with and without internal frames. The experimental process is based on scanning laser vibrometer measurements of the vibrations on the surface of the shell. A transform of the vibratory field in the wavenumber domain is then performed. It allows estimating the far-field radiated pressure with the stationary phase theorem. An increase of the radiation efficiency is observed in the low frequencies. Analysis of the velocity field in the physical and wavenumber spaces allows highlighting the coupling of the circumferential orders at the origin of the increase in the radiation efficiency.

    Moyamoya disease is a cerebrovascular condition that results in the narrowing of the vessels of the circle of Willis and collateral vessel formation at the base of the brain. Although relationships between Graves' disease and cerebrovascular accidents in Moyamoya disease are obscure, the coexistence of the two diseases is noteworthy. Moyamoya disease has been rarely reported in adolescent patients with thyrotoxicosis. Recently, we encountered two adolescent Korean patients with Moyamoya disease associated with Graves' disease who presented with episodic right-sided hemiparesis and syncope. These two girls who had Graves' disease had no history of other diseases or head trauma. A thyroid function test revealed a euthyroid state and a high thyroid-stimulating hormone (TSH) receptor antibody titer at that time. The patients were diagnosed with Moyamoya disease based on brain magnetic resonance angiography and cerebral four-vessel angiography. The patients underwent cranial revascularization by encephalo-duroarterio-synangiosis as soon as a diagnosis was made, which resulted in successful symptom resolution. They fared well and had no additional neurological symptoms as of their last follow-up visits. Here, we report these two cases of confirmed Moyamoya disease complicated by Graves' disease with a review of the literature, and discuss the possible association between the two diseases. To our knowledge, this is the first report in South Korea on Moyamoya disease associated with Graves' disease in adolescents with a euthyroid.

    The design and theoretical basis of a new database tool that quickly generates vibroacoustic response estimates using a library of transfer functions (TFs) is discussed. During the early stages of a launch vehicle development program, these response estimates can be used to provide vibration environment specification to hardware vendors. The tool accesses TFs from a database, combines the TFs, and multiplies these by input excitations to estimate vibration responses. The database is populated with two sets of uncoupled TFs; the first set representing vibration response of a bare panel, designated as H(sup s), and the second set representing the response of the free-free component equipment by itself, designated as H(sup c). For a particular configuration undergoing analysis, the appropriate H(sup s) and H(sup c) are selected and coupled to generate an integrated TF, designated as H(sup s +c). This integrated TF is then used with the appropriate input excitations to estimate vibration responses. This simple yet powerful tool enables a user to estimate vibration responses without directly using finite element models, so long as suitable H(sup s) and H(sup c) sets are defined in the database libraries. The paper discusses the preparation of the database tool and provides the assumptions and methodologies necessary to combine H(sup s) and H(sup c) sets into an integrated H(sup s + c). An experimental validation of the approach is also presented.

    The decision to offer radiotherapy in patients with connective tissue diseases continues to be challenging. Radiotherapy might trigger the onset of connective tissue diseases by increasing the expression of self-antigens, diminishing regulatory T-cell activity, and activating effectors of innate immunity (dendritic cells) through Toll-like receptor-dependent mechanisms, all of which could potentially lead to breaks of immune tolerance. This potential risk has raised some debate among radiation oncologists about whether patients with connective tissue diseases can tolerate radiation as well as people without connective tissue diseases. Because the number of patients with cancer and connective tissue diseases needing radiotherapy will probably increase due to improvements in medical treatment and longer life expectancy, the issue of interactions between radiotherapy and connective tissue diseases needs to be clearer. In this Review, we discuss available data and evidence for patients with connective tissue diseases treated with radiotherapy. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Addison's disease is a rare disorder in patients with end-stage renal disease (ESRD). In patients, the diagnosis of Addison's disease is difficult in clinical practice because most of the clinical findings of this disease are similar to those of the renal failure. We present a 51-year-old male patient, who underwent hemodialysis therapy for 8 years, diagnosed with Addison's disease after having myalgia, skin hyperpigmentation, weight loss, sweating, and nausea for the past few weeks. The physical examination was completely normal except for muscle weakness, hyperpigmentation on labial mucosa and skin in a patient. The laboratory tests revealed anemia and hypoglycemia. Serum cortisol, adrenocorticotropic hormone (ACTH) levels, and ACTH stimulation test results were consistent with Addison's disease. Adrenal computerized tomography revealed bilateral atrophic glands. Additionally, it was found that elevated serum thyroid stimulating hormone levels and antithyroid peroxidase antibody titer were positive. Our purpose is to emphasize that physicians should be alert to the potential for additional different conditions particularly in terms of adrenal failure in patients with ESRD.

    The aim of the study was to determine the blood serum sulfated glycosaminoglycans (GAGs) and hyaluronic acid (HA) concentration of Graves' disease patients before treatment and after attainment of the euthyroid state. The study was carried out on the blood serum obtained from 17 patients with newly recognised Graves' disease and from the same patients after attainment of the euthyroid state. Graves' patients had not any clinical symptoms neither of ophthalmopathy nor pretibial myxedema. GAGs were isolated from the blood serum by the multistage extraction and purification using papaine hydrolysis, alkali elimination, as well as cetylpyridium chloride binding. Total amount of GAGs was quantified by the hexuronic acids assay. HA content in obtained GAGs sample was evaluated by the ELISA method. Increased serum concentration of sulfated GAGs in non-treated Graves' disease patients was found. Similarly, serum HA level in untreated patients was significantly elevated. The attainment of euthyroid state was accompanied by the decreased serum sulfated GAGs level and by normalization of serum HA concentration. In conclusion, the results obtained demonstrate that the alterations of GAGs metabolism connected with Graves' disease can lead to systemic changes of the extracellular matrix properties.

    To evaluate the incidence of thyroid carcinoma in patients operated on for Graves' disease, to identify criteria which may predict malignancy, and to develop a practical approach to determine the extensiveness of thyroidectomy. Retrospective study of all patients who underwent thyroidectomy for Graves' disease between 1995 and 2005. 547 patients underwent subtotal thyroidectomy for Graves' disease during this period. Post-operative pathology examination revealed six cases of thyroid cancer (1.1%). All six cases had differentiated thyroid carcinoma (papillary carcinoma in 3 cases, follicular carcinoma in 2 cases and papillo-follicular carcinoma in 1 case). The indication for initial thyroidectomy was a palpable thyroid nodule in 3 cases (50%), failure of medical treatment for Grave's disease in 2 cases (33%), and signs of goiter compression in 1 case (17%). Five patients underwent re-operative total thyroidectomy. This study shows that while malignancy in Grave's disease is uncommon, the presence of thyroid nodule(s) in patients with Grave's disease may be considered as an indication for radical surgery. The most adequate radical surgery in this situation is to perform a total thyroidectomy.

    Chronic obstructive airway disease (COPD) is considered as risk factor for coronary artery disease (CAD) along with other risk factors. This study was conducted to determine the frequency of undiagnosed chronic obstructive pulmonary disease in patients with coronary artery disease. Methods: This cross-sectional study was conducted in the Pulmonology and Cardiology wards/OPD's of Khyber Teaching Hospital Peshawar. Patients more than 35 years of age, diagnosed with CAD of either gender were included. Patients already diagnosed with COPD, recent myocardial infarction (within 7 days), left ventricular impairment, pneumothorax, bronchiectasis, comatose patient, asthmatic and those with chest trauma were excluded. All the patients underwent spirometry examination before and after administration of salbutamol (5 mg for 5 minutes) via nebulizer. FEV1/FVC less than 70% confirmed the presence of COPD. Results: Out of 151 patients, 57 (37.7%) were found to have COPD. Among them, 39 (68.42%) were male and 18 (31.57%) were female. Among male patients with COPD, 82.05% (n=32) were smokers and 17.94% (n=7) were nonsmokers while in females with COPD no one was smoker. Conclusion: COPD is an under-diagnosed progressive disease in patients with high risk patients with coronary artery disease. (author)

    Full Text Available Invasive fungal diseases (IFDs are an important factor affecting the prognosis of patients with severe liver diseases, and their early diagnosis remains a challenge for clinicians. The four most commonly seen IFDs are candidiasis, aspergillosis, cryptococcosis, and pneumocystis pneumonia. We should pay attention to the risk of developing IFDs in patients with severe liver diseases during clinical management. Particularly, early diagnosis and proper treatment of IFDs are important in high-risk patients. These are vital to improving the prognosis of patients with severe liver diseases.

    Celiac disease is a multi-system disorder with manifestations that may result in psychiatric disorders. We assessed the prevalence of medication use to treat psychiatric disorders in celiac disease patients. We conducted a cross-sectional study of patients undergoing esophagogastroduodenoscopy over 9-years at a celiac disease referral center. We compared the prevalence of psychotropic medication use among celiac disease patients (n = 1293) to a control group (n = 1401) with abdominal pain or reflux. Among all patients the mean age was 48.4 years, most were female (69.5%), and 22.7% used any psychotropic medication. There was no difference between overall psychotropic medication use among celiac disease patients and controls (23.9% vs 21.8%, OR 1.16; 95% CI 0.96-1.39, p = 0.12). However, those with celiac disease were more likely to use antidepressants on univariate (16.4% vs 13.4%, p = 0.03) and multivariate analysis (OR 1.28; 95% CI 1.03-1.59; p = 0.03). Use of psychotropic medications was not associated with disease duration or mode of presentation of celiac disease. Celiac disease patients use psychotropic medications at similar rates as those with other gastrointestinal diseases, though subgroup analysis suggests they may use more antidepressants. Future studies should investigate whether celiac disease is associated with mood disorders that are not treated with medications.

    Patient education forms a cornerstone of management of inflammatory bowel disease (IBD). The Internet has opened new avenues for information gathering. To determine the relationship between different information sources and patient knowledge and anxiety in patients with IBD. The use of information sources in patients with IBD was examined via questionnaire. Anxiety was assessed with the hospital anxiety and depression scale and disease-related patient knowledge with the Crohn's and colitis knowledge score questionnaires. Associations between these outcomes and demographics, disease-related factors, and use of different information sources were analysed using linear regression analysis. Of 307 patients (165 Crohn's disease, 142 ulcerative colitis) 60.6% were female. Participants used the hospital IBD team (82.3%), official leaflets (59.5%), and official websites (53.5%) most frequently in contrast to alternative health websites (9%). University education (P sex (P = 0.004), clinically active disease (P sources are associated with better knowledge or worse anxiety levels. Face-to-face education and written information materials remain the first line of patient education. Patients should be guided towards official information websites and warned about the association between the use of alternative health websites or random links and anxiety. © 2016 John Wiley & Sons Ltd.

    Patients with congenital heart disease have a number of risk factors for the development of chronic kidney disease (CKD). It is well known that CKD has a large negative impact on health outcomes. It is important therefore to consider that patients with congenital heart disease represent a population in whom long-term primary and secondary prevention strategies to reduce CKD occurrence and progression could be instituted and significantly change outcomes. There are currently no clear guidelines for clinicians in terms of renal assessment in the long-term follow up of patients with congenital heart disease. Consolidation of knowledge is critical for generating such guidelines, and hence is the purpose of this view. This review will summarize current knowledge related to CKD in patients with congenital heart disease, to highlight important work that has been done to date and set the stage for further investigation, development of prevention strategies, and re-evaluation of appropriate renal follow-up in patients with congenital heart disease. The literature search was conducted using PubMed and Google Scholar. Current epidemiological evidence suggests that CKD occurs in patients with congenital heart disease at a higher frequency than the general population and is detectable early in follow-up (i.e. during childhood). Best evidence suggests that approximately 30 to 50 % of adult patients with congenital heart disease have significantly impaired renal function. The risk of CKD is higher with cyanotic congenital heart disease but it is also present with non-cyanotic congenital heart disease. Although significant knowledge gaps exist, the sum of the data suggests that patients with congenital heart disease should be followed from an early age for the development of CKD. There is an opportunity to mitigate CKD progression and negative renal outcomes by instituting interventions such as stringent blood pressure control and reduction of proteinuria. There is a need to

    In the present study, we compared explicit memory performance, using the Wechsler Memory Scale, and implicit memory performance, using the Nissen software version of the serial reaction time task, in patients with Wilson's disease to normal controls. The Wilson's disease patients exhibited deficits in explicit memory tasks, such as figure recall and understanding memory. Moreover, the Wilson's disease patients exhibited deficits in implicit memory tasks, including significantly prolonged response times. These findings indicate that Wilson's disease patients have explicit and implicit partial memory impairments.

    Background This study was conducted to determine whether patients with Gaucher disease had significant dental pathology because of abnormal bone structure, pancytopenia, and coagulation abnormalities. Methods Each patient received a complete oral and periodontal examination in addition to a routine hematological evaluation. Results Gaucher patients had significantly fewer carious lesions than otherwise healthy carriers. Despite prevalence of anemia, there was no increase in gingival disease; despite the high incidence of thrombocytopenia, gingival bleeding was not noted; and despite radiological evidence of bone involvement, there was no greater incidence loss of teeth or clinical tooth mobility. Conclusions These data represent the first survey of the oral health of a large cohort of patients with Gaucher disease. It is a pilot study of a unique population and the results of the investigation are indications for further research. Based on our findings, we recommend regular oral examinations with appropriate dental treatment for patients with Gaucher disease as for other individuals. Consultation between the dentist and physician, preferably one with experience with Gaucher disease, should be considered when surgical procedures are planned. PMID:12875661

    Full Text Available Background: Ultrasound observation of fetal movement has documented general trends in motor development and fetal age when motor response to stimulation is observed. Evaluation of fetal movement quality, in addition to specific motor activity, may improve documentation of motor development and highlight specific motor responses to stimulation. Aims: The aim of this investigation was to assess fetal movement at 26 and 36 weeks gestation during three conditions (baseline, immediate response to vibro-acoustic stimulation (VAS, and post-response. Design: A prospective, longitudinal design was utilized. Subjects: Twelve normally developing fetuses, 8 females and 4 males, were examined with continuous ultrasound imaging. Outcome measures: The Fetal Neurobehavioral Coding System (FENS was used to evaluate the quality of motor activity during 10-second epochs over the three conditions. Results: Seventy-five percent of the fetuses at the 26 week assessment and 100% of the fetuses at the 36 week assessment responded with movement immediately following stimulation. Significant differences in head, fetal breathing, general, limb, and mouthing movements were detected between the 26 week and 36 week assessments. Movement differences between conditions were detected in head, fetal breathing, limb, and mouthing movements. Conclusions: Smoother and more complex movement was observed with fetal maturation. Following VAS stimulation, an immediate increase of large, jerky movements suggest instability in fetal capabilities. Fetal movement quality changes over gestation may reflect sensorimotor synaptogenesis in the central nervous system, while observation of immature movement patterns following VAS stimulation may reflect movement pattern instability.

    The purpose of this study was to evaluate the role of CT in patients with and without prostatic disease. CT and MR findings were reviewed in 25 patients without known prostatic disease, 11 patients with benign prostatic hyperplasia and 11 patients with prostatic cancer. Differential attenuation allowed for distinction of the peripheral zone and inner gland of the prostate by CT in 72% of normal patients. The distinction rate of prostatic zonal anatomy by CT decreased to 30% in the diseased group. When zonal anatomy of the prostate is not visualized on pelvic enhanced CT, the presence of prostatic disease might be considered. (author)

    Brain tissue analysis is necessary to confirm prion diseases. Clinically unsuspected cases may be identified through neuropathologic testing. National Alzheimer's Coordinating Center (NACC) Minimum and Neuropathologic Data Set for 1984 to 2005 were reviewed. Eligible patients had dementia, underwent autopsy, had available neuropathologic data, belonged to a currently funded Alzheimer's Disease Center (ADC), and were coded as having an Alzheimer's disease clinical diagnosis or a nonprion disease etiology. For the eligible patients with neuropathology indicating prion disease, further clinical information, collected from the reporting ADC, determined whether prion disease was considered before autopsy. Of 6000 eligible patients in the NACC database, 7 (0.12%) were clinically unsuspected but autopsy-confirmed prion disease cases. The proportion of patients with dementia with clinically unrecognized but autopsy-confirmed prion disease was small. Besides confirming clinically suspected cases, neuropathology is useful to identify unsuspected clinically atypical cases of prion disease. © The Author(s) 2015.

    Celiac disease is an autoimmune, gastrointestinal disorder characterized by intolerance to the dietary grain protein gluten. An increased prevalence of celiac disease has been reported in Down syndrome and Turner syndrome, but there has been only few previous reports with respect to the association of celiac disease in Williams-Beuren syndrome. The aim of this study was to evaluate the frequency of celiac disease in our 24 Williams-Beuren syndrome patients. Gastrointestinal problems and celiac disease symptoms of patients were noted. All patients were analyzed by the titer of tissue transglutaminases IgA and IgG. HLA genotyping and intestinal biopsy was performed to the patients with positive serology. We also performed gluten free diet in the presence of compatible symptoms, serology, HLA genotyping and intestinal biopsy. In our study, two patients had positive tTG antibodies, but only one had positive biopsy finding for celiac disease. The frequency of celiac disease in patients with Williams-Beuren syndrome was estimated as 1/24 (4.1%). Though the number of participants in this study was limited, the results show that the frequency of celiac disease is higher in Williams-Beuren syndrome compared to the general population. We suggest that a high suspicion and testing for celiac disease should be recommended at certain intervals in all cases with Williams-Beuren syndrome to detect the cause of growth retardation and gastrointestinal problems.

    To evaluate the spectrum of mineral abnormalities and bone disease (BD) in hemodialysis patients at Jordan University Hospital (JUH), Amman, Jordan. A cross-sectional study was conducted among 63 patients (38 males and 25 females), mean age 44.19 years (range 17-76 years), with chronic kidney disease (CKD) on regular hemodialysis at JUH between November 2004 and April 2005. All patients have undergone complete blood count, chemistry profile, alkaline phosphatase, serum albumin, intact parathyroid hormone (iPTH) and plain x-rays. Bone disorders were identified in 45 patients on x-rays (70%). Osteopenia was found in 43 patients (68.3%), subperiosteal resorption in 24 patients (38.3%) and metastatic calcification in 22 patients (35%). Hypocalcemia was found in 28.6% and hypercalcemia in 7.9%. All patients were taking calcium carbonate, and 55.5% of patients were on vitamin D supplements. The calcium levels in 63.5% and the phosphorus levels in 50.8% of patients were within the recommended guidelines of the National Kidney Foundation Kidney Disease Outcomes Quality Initiative (K/DOQI). Serum i-PTH level was above 300 pg/ml high turnover bone disease in 24.6% of patients, 21.3% had iPTH of 150-300 pg/ml target, and 44.3% had i-PTH levels below 100 pg/mL suggesting a dynamic bone disease. Patients with severe bone disease had a statistically significant higher iPTH levels (p<0.005). Bone disease and mineral abnormalities are common in hemodialysis patients at JUH. Earlier detection of bone disease and better overall management strategy may reduce the frequency and severity of bone disease in CKD patients in Jordan. (author)

    Fabry's disease is an X-linked inherited, rare, progressive, lysosomal storage disorder, affecting multiple organs due to the deficient activity of α-galactosidase A (α-Gal A) enzyme. The prevalence has been reported to be 0.15-1% in hemodialysis patients; however, the information on the prevalence in chronic kidney disease not on dialysis is lacking. This study aimed to determine the prevalence of Fabry's disease in chronic kidney disease. The patients older than 18 years, enclosing KDIGO 2012 chronic kidney disease definitions, not on dialysis, were enrolled. Dried blood spots on Guthrie papers were used to analyze α-Gal A enzyme and genetic analysis was performed in individuals with enzyme activity ≤1.2 μmol/L/h. A total of 1453 chronic kidney disease patients not on dialysis from seven clinics in Turkey were screened. The mean age of the study population was 59.3 ± 15.9 years. 45.6% of patients were female. The creatinine clearance of 77.3% of patients was below 60 mL/min/1.73 m 2 , 8.4% had proteinuria, and 2.5% had isolated microscopic hematuria. The mean value of patients' α-Gal A enzyme was detected as 2.93 ± 1.92 μmol/L/h. 152 patients had low levels of α-Gal A enzyme activity (≤1.2 μmol/L/h). In mutation analysis, A143T and D313Y variants were disclosed in three male patients. The prevalence of Fabry's disease in chronic kidney disease not on dialysis was found to be 0.2% (0.4% in male, 0.0% in female). Fabry's disease should be considered in the differential diagnosis of chronic kidney disease with unknown etiology even in the absence of symptoms and signs suggestive of Fabry's disease.

    Celiac disease, once thought to be uncommon in Asia, is now recognized in Asian nations as well. We investigated the prevalence of celiac disease in first-degree relatives of celiac disease patients followed in our centre. First-degree relatives were screened prospectively for celiac disease using questionnaire-based interview and anti-tissue transglutaminase antibody. Serology positive first-degree relatives underwent duodenal biopsies. Diagnosis of celiac disease was made based on positive serology and villous abnormality Marsh grade 2 or higher. Human leucocyte antigen DQ2/-DQ8 was also assessed in 127 first-degree relatives. 434 first-degree relatives of 176 celiac disease patients were prospectively recruited; 282 were symptomatic (64.9%), 58 were positive for serology (13.3%). Seroprevalence was higher in female than in males (19% vs 8.5%; p=0.001) and highest in siblings (16.9%) than parents (13.6%) and children (5.9%) of celiac patients (p=0.055); 87.4% first-degree relatives were human leucocyte antigen-DQ2/-DQ8 positive. Overall prevalence of celiac disease was 10.9% amongst first-degree relatives. The prevalence of celiac disease in first-degree relatives of celiac disease patients was 10.9% in our cohort, and 87% had human leucocyte antigen-DQ2 or -DQ8 haplotype. All first-degree relatives of celiac disease patients should be screen for celiac disease even if asymptomatic or with atypical manifestations.

    Objective: Celiac disease (CD) is a common, lifelong disease with small bowel malabsorption based on genetically conditioned gluten intolerance. The clinical manifestation could be very heterogeneous. The proof of celiac disease is now based mainly on clinical and laboratory (antibodies and enterobiopsy) signs, which are in some cases problematic and inconvenient. Materials and methods: In our study we have examined 250 patients with suspection or with proven celiac disease and we evaluated specific ultrasound small bowel changes in this group. In the next step, we chose 59 patients with laboratory proved celiac disease and we statistically compared ultrasound, other laboratory and clinical findings in different forms and stages of the disease. Results: Specific small bowel pathologies in patients with celiac disease (like changes of intestinal villi in different parts of small bowel, abnormal peristalsis and mesenterial lymphadenopathy) can be well visualized by ultrasound and in combination with clinical and laboratory signs ultrasound examination could have an important role in screening, determination of diagnosis and monitoring of patients with different forms of celiac disease.

    Patients with liver disease are at increased risks of both thrombotic and bleeding complications. Many have atrial fibrillation (AF) or venous thromboembolism (VTE) necessitating oral anticoagulant agents (OACs). Recent evidence has contradicted the assumption that patients with liver disease are "auto-anticoagulated" and thus protected from thrombotic events. Warfarin and non-vitamin K-antagonist OACs have been shown to reduce thrombotic events safely in patients with either AF or VTE. However, patients with liver disease have largely been excluded from trials of OACs. Because all currently approved OACs undergo metabolism in the liver, hepatic dysfunction may cause increased bleeding. Thus, the optimal anticoagulation strategy for patients with AF or VTE who have liver disease remains unclear. This review discusses pharmacokinetic and clinical studies evaluating the efficacy and safety of OACs in patients with liver disease and provides a practical, clinically oriented approach to the management of OAC therapy in this population.

    IBEX-Hi is an electrostatic analyzer spacecraft instrument designed to measure the energy and flux distribution of energetic neutral atoms (ENAs) emanating from the interaction zone between the Earth's solar system and the Milky Way galaxy. A key element to this electro-optic instrument is an array of fourteen carbon foils that are used to ionize the ENAs. The foils are comprised of an ultrathin (50-100 {angstrom} thick) layer of carbon suspended across the surface of an electroformed Nickel wire screen, which in turn is held taught by a metal frame holder. The electro formed orthogonal screen has square wire elements, 12.7 {micro}m thick, with a pitch of 131.1 wires/cm. Each foil holder has an open aperture approximately 5 cm by 2.5 cm. Designing and implementing foil holders with such a large surface area has not been attempted for spaceflight in the past and has proven to be extremely challenging. The delicate carbon foils are subject to fatigue failure from the large acoustic and vibration loads that they will be exposed to during launch of the spacecraft. This paper describes the evolution of the foil holder design from previous space instrument applications to a flight-like IBEX-Hi prototype. Vibro-acoustic qualification tests of the IBEX-Hi prototype instrument and the resulting failure of several foils are summarized. This is followed by a discussion of iterative foil holder design modifications and laser vibrometer modal testing to support future fatigue failure analyses, along with additional acoustic testing of the IBEX-Hi prototype instrument. The results of these design and testing activities are merged and the resulting flight-like foil holder assembly is proposed.

    Poor color discrimination among patients with Parkinson disease (PD) has long been recognized. It has been shown that carrying one or two mutations in the β-glucocerebrosidase gene (GBA) for the autosomal disease Gaucher disease (GD), as based initially on clinical evidence, is a genetic risk factor for early-onset PD. The purpose of this study was to assess color discrimination in patients with one or two GBA mutations relative to healthy controls to ascertain whether this function is affected when persons with GD or even one GBA mutation develop PD. The Farnsworth-Munsell 100 hue test (FMHT) was evaluated among patients with GD+PD compared to patients with GD only, obligate GBA carriers with and without PD, patients with PD only, and healthy controls. FMHT outcome include computer-generated TES (Total Error Score) and values recommended by Vingrys & King-Smith. Six groups of 10 persons were tested. Significant differences were seen for male GD+PD and for age in PD. The highest mean TES was in the PD only group, the lowest in the GD only group. There was a significant difference because of PD in groups with GD and GBA carriers. GD+PD means were between GD only and PD only mean scores. These findings confirm that PD impacts color discrimination, more in males with GD+PD but nonetheless, GD+PD patients (but not GBA carriers) had better scores than PD only patients.

    Cognitive impairment, which frequently occurs in patients with schizophrenia, bipolar disorder, Alzheimer's disease, and Parkinson's disease, has a significant impact on the daily lives of both patients and their family. Furthermore, since the medications used for cognitive enhancement have limited efficacy, the issue of cognitive enhancement still remains a clinically unsolved challenge. We reviewed the clinical studies (published between 2007 and 2017) that focused on the efficacy of medications used for enhancing cognition in patients with schizophrenia, bipolar disorder, Alzheimer's disease, and Parkinson's disease. Acetylcholinesterase inhibitors and memantine are the standard treatments for Alzheimer's disease and Parkinson's disease. Some studies have reported selective cognitive improvement in patients with schizophrenia following galantamine treatment. Newer antipsychotics, including paliperidone, lurasidone, aripiprazole, ziprasidone, and BL-1020, have also been reported to exert cognitive benefits in patients with schizophrenia. Dopaminergic medications were found to improve language function in patients with Parkinson's disease. However, no beneficial effects on cognitive function were observed with dopamine agonists in patients with schizophrenia. The efficacies of nicotine and its receptor modulators in cognitive improvement remain controversial, with the majority of studies showing that varenicline significantly improved the cognitive function in schizophrenic patients. Several studies have reported that N -methyl-d-aspartate glutamate receptor (NMDAR) enhancers improved the cognitive function in patients with chronic schizophrenia. NMDAR enhancers might also have cognitive benefits in patients with Alzheimer's disease or Parkinson's disease. Raloxifene, a selective estrogen receptor modulator, has also been demonstrated to have beneficial effects on attention, processing speed, and memory in female patients with schizophrenia.

    Inflammatory bowel disease (IBD) patients have an increased risk for thromboembolism. The aim of this study was to assess the presence of thrombophilic risk factors in IBD patients and to assess the associations of these factors with disease activity. Forty-eight patients with IBD (24 ulcerative colitis, 24 Crohn's disease) and 40 matched healthy control individuals were enrolled. In addition to routine biochemical analysis, fasting blood samples were studied for prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen, protein-C, protein-S, antithrombin III, factor VII, factor VIII, D-dimer, vitamin B 12 , folic acid and homocysteine. Levels of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), fibrinogen, D-dimer and the number of platelets were significantly higher in patients with IBD. When compared to control group, in patients with Crohn's disease serum homocystein levels were significantly higher (p = 0.025) while serum folic acid levels were significantly lower (p homocystein and the number of platelets were found to be significantly higher in Crohn's disease patients who were in active period of the disease. Thrombophilic defects are multifactorial and might be frequently seen in IBD patients. They might contribute to thrombotic complications of this disease.

    Patients with chronic heart failure (HF) are limited in their quality of life, have a poor prognosis and face frequent hospitalisations. Patient self-management was shown to improve quality of life, reduce rehospitalisations and costs in patients with chronic HF. Comprehensive disease management programmes are critical to foster patient self-management. The chronic care model developed by the WHO serves as the basis of such programmes. In order to develop self-management skills a needs orientated training concept is mandatory, as patients need both knowledge of the illness and the ability to use the information to make appropriate decisions according to their individual situation. Switzerland has no established system for the care of patients with chronic diseases in particular those with HF. For this reason a group of Swiss experts for HF designed a model for disease management for HF patients in Switzerland. Since 2009 the Swiss Heart Foundation offers an education programme based on this model. The aim of this programme is to offer education and support for practitioners, patients and families. An initial pilot evaluation of the program showed mixed acceptance by practitioners, whereas patient assessed the program as supportive and in line with their requirements.

    Several heart diseases are promoters of left-side cardiac thrombosis and could lead to arterial embolism. The same mechanism may be responsible for right-side cardiac thrombosis and therefore be a direct source of pulmonary embolism. Yasuoka et al. showed a higher incidence of perfusion defects in lung scan in patients with spontaneous echocontrast in the right atrium than in those without it (40% and 7% respectively; P=0.006). We recently assessed the prevalence of heart diseases in 11.236 consecutive patients older than 60 years discharged from Venetian hospitals with a diagnosis of pulmonary embolism. We observed a higher prevalence of all-cause heart diseases (odds ratio 1.26; 95% confidence interval, 1.13-1.40) in patients with a diagnosis of pulmonary embolism alone (secondary or unprovoked) compared with those discharged with a diagnosis of pulmonary embolism associated with deep vein thrombosis, generating the hypothesis that some specific heart diseases in older patients could themselves be a possible source of pulmonary emboli. Further prospective studies are required to confirm these findings, which have the potential to open new horizons for the interpretation and management of venous thromboembolic disease.

    Full Text Available The prevalence of celiac disease autoimmunity or tissue transglutaminase autoantibodies (TGA amongst patients with type 1 diabetes (T1D and autoimmune thyroid disease (AITD in the Chinese population remains unknown. This study examined the rate of celiac disease autoimmunity amongst patients with T1D and AITD in the Chinese population. The study included 178 patients with type 1 diabetes and 119 with AITD where 36 had both T1D and AITD, classified as autoimmune polyglandular syndrome type 3 variant (APS3v. The study also included 145 patients with type 2 diabetes (T2D, 97 patients with non-autoimmune thyroid disease (NAITD, and 102 healthy controls. Serum islet autoantibodies, thyroid autoantibodies and TGA were measured by radioimmunoassay. TGA positivity was found in 22% of patients with either type 1 diabetes or AITD, much higher than that in patients with T2D (3.4%; p< 0.0001 or NAITD (3.1%; P < 0.0001 or healthy controls (1%; p<0.0001. The patients with APS3v having both T1D and AITD were 36% positive for TGA, significantly higher than patients with T1D alone (p = 0.040 or with AITD alone (p = 0.017. T1D and AITD were found to have a 20% and 30% frequency of overlap respectively at diagnosis. In conclusion, TGA positivity was high in the Chinese population having existing T1D and/or AITD, and even higher when both diseases were present. Routine TGA screening in patients with T1D or AITD will be important to early identify celiac disease autoimmunity for better clinical care of patients.

    To assess the combined effect of disease phenotype, smoking and medical therapy [steroid, azathioprine (AZA), AZA/biological therapy] on the probability of disease behavior change in a Caucasian cohort of patients with Crohn's disease (CD). Three hundred and forty well-characterized, unrelated, consecutive CD patients were analyzed (M/F: 155/185, duration: 9.4 +/- 7.5 years) with a complete clinical follow-up. Medical records including disease phenotype according to the Montreal classification, extraintestinal manifestations, use of medications and surgical events were analyzed retrospectively. Patients were interviewed on their smoking habits at the time of diagnosis and during the regular follow-up visits. A change in disease behavior was observed in 30.8% of patients with an initially non-stricturing, non-penetrating disease behavior after a mean disease duration of 9.0 +/- 7.2 years. In a logistic regression analysis corrected for disease duration, perianal disease, smoking, steroid use, early AZA or AZA/biological therapy use were independent predictors of disease behavior change. In a subsequent Kaplan-Meier survival analysis and a proportional Cox regression analysis, disease location (P = 0.001), presence of perianal disease (P < 0.001), prior steroid use (P = 0.006), early AZA (P = 0.005) or AZA/biological therapy (P = 0.002), or smoking (P = 0.032) were independent predictors of disease behavior change. Our data suggest that perianal disease, small bowel disease, smoking, prior steroid use, early AZA or AZA/biological therapy are all predictors of disease behavior change in CD patients.

  13. Novel combined management approaches to patients with diabetes, chronic kidney disease and cardiovascular disease.

    Most patients we care for today suffer from more than one chronic disease, and multimorbidity is a rapidly growing challenge. Concomitant cardiovascular disease, renal dysfunction and diabetes represent a large proportion of all patients in cardiology, nephrology and diabetology. These entities commonly overlap due to their negative effects on vascular function and an accelerated atherosclerosis progression. At the same time, a progressive subspecialisation has caused the cardiologist to treat 'only' the heart, nephrologists 'only' the kidneys and endocrinologists' 'only' diabetes. Studies and guidelines follow the same pattern. This often requires patients to visit specialists for each field, with a risk of both under-diagnosis and under-treatment. From the patient's perspective, there is a great need for coordination and facilitation of the care, not only to reduce disease progression but also to improve quality of life. Person-centred integrated clinics for patients with cardiovascular disease, renal dysfunction and diabetes are a promising approach for complex chronic disease management.

    A substantial proportion of chronic disease patients do not respond to self-management interventions, which suggests that one size interventions do not fit all, demanding more tailored interventions. To compose more individualized strategies, we aim to increase our understanding of characteristics associated with patient activation for self-management and to evaluate whether these are disease-transcending. A cross-sectional survey study was conducted in primary and secondary care in patients with type-2 Diabetes Mellitus (DM-II), Chronic Obstructive Pulmonary Disease (COPD), Chronic Heart Failure (CHF) and Chronic Renal Disease (CRD). Using multiple linear regression analysis, we analyzed associations between self-management activation (13-item Patient Activation Measure; PAM-13) and a wide range of socio-demographic, clinical, and psychosocial determinants. Furthermore, we assessed whether the associations between the determinants and the PAM were disease-transcending by testing whether disease was an effect modifier. In addition, we identified determinants associated with low activation for self-management using logistic regression analysis. We included 1154 patients (53% response rate); 422 DM-II patients, 290 COPD patients, 223 HF patients and 219 CRD patients. Mean age was 69.6±10.9. Multiple linear regression analysis revealed 9 explanatory determinants of activation for self-management: age, BMI, educational level, financial distress, physical health status, depression, illness perception, social support and underlying disease, explaining a variance of 16.3%. All associations, except for social support, were disease transcending. This study explored factors associated with varying levels of activation for self-management. These results are a first step in supporting clinicians and researchers to identify subpopulations of chronic disease patients less likely to be engaged in self-management. Increased scientific efforts are needed to explain the greater

    Several surgical treatments can be employed for the patients with neurological disorders, such as multiple sclerosis, Guillain-Barré syndrome, Parkinson's disease, amyotrophic lateral sclerosis, Alzheimer disease and spinal cord injury. It is possible that anesthesia related complications are induced in these neurologically complicated patients in the perioperative period. Respiratory dysfunction and autonomic nervous system dysfunction are most common in this population. Respiratory muscle weakness and bulbar palsy may cause aspiration pneumonia. Sometimes, postoperative ventilatory support is mandatory in these patients. Autonomic nervous system dysfunction may cause hypotension secondary to postural changes, blood loss, or positive airway pressure. Some therapeutic agents prescribed for neurological symptoms have drug interaction with anesthetic agents. Patients with motor neuron disease should be considered to be vulnerable to hyperkalemia in response to a depolarizing muscle relaxant. Although perioperative treatment guideline for most neurologic disorders has not been reported to lessen perioperative morbidity, knowledge of the clinical features and the interaction of common anesthetics with the drug therapy is important in planning intraoperative and postoperative management.

    Variable mortality rates have been reported for patients with rheumatic diseases admitted to an intensive care unit (ICU). Due to the absence of appropriate control groups in previous studies, it is not known whether the presence of a rheumatic disease constitutes a risk factor. Moreover, the accuracy of the Acute Physiology and Chronic Health Evaluation II (APACHE II) score for predicting outcome in this group of patients has been questioned. The primary goal of this study was to compare outcome of patients with rheumatic diseases admitted to a medical ICU to those of controls. The records of all patients admitted between 1 April 2003 and 30 June 2014 (n=4020) were screened for the presence of a rheumatic disease during admission (n=138). The diagnosis of a rheumatic disease was by standard criteria for these conditions. An age- and gender-matched control group of patients without a rheumatic disease was extracted from the patient population in the database during the same period (n=831). Mortality in ICU, in hospital and after 180 days did not differ significantly between patients with and without rheumatic diseases. There was no difference in the performance of the APACHE II score for predicting outcome in patients with rheumatic diseases and controls. This score, as well as a requirement for the use of inotropes or vasopressors, accurately predicted hospital mortality in the group of patients with rheumatic diseases. In conclusion, patients with a rheumatic condition admitted to intensive care do not do significantly worse than patients without such a disease.

    Full Text Available Epiretinal membranes (ERMs in Stargardt disease have been known to undergo spontaneous separation in children. Results of surgical intervention in adult patients with Stargardt disease have rarely been reported. A retrospective review of results of surgical intervention for ERM causing visual impairment in two adult patients of Stargardt disease was carried out. Both patients developed ERM in one eye during their follow-up period with the resultant drop in their preexisting visual acuity. Postsurgery, restoration of foveal contour with some improvement in visual acuity was observed in both patients. No adverse effect of surgery was noted.

    Full Text Available Background/Aims: Fabry disease is a treatable cause of chronic kidney disease (CKD characterized by a genetic deficiency of α-galactosidase A. European Renal Best Practice (ERBP recommends screening for Fabry disease in CKD patients. However, this is based on expert opinion and there are no reports of the prevalence of Fabry disease in stage 1-5 CKD. Hence, we investigated the prevalence of Fabry disease in CKD patients not receiving renal replacement therapy. Methods: This prospective study assessed α-galactosidase activity in dried blood spots in 313 stage 1-5 CKD patients, 167 males, between ages of 18-70 years whose etiology of CKD was unknown and were not receiving renal replacement therapy. The diagnosis was confirmed by GLA gene mutation analysis. Results: Three (all males of 313 CKD patients (0.95% were diagnosed of Fabry disease, for a prevalence in males of 1.80%. Family screening identified 8 aditional Fabry patients with CKD. Of a total of 11 Fabry patients, 7 were male and started enzyme replacement therapy and 4 were female. The most frequent manifestations in male patients were fatigue (100%, tinnitus, vertigo, acroparesthesia, hypohidrosis, cornea verticillata and angiokeratoma (all 85%, heat intolerance (71%, and abdominal pain (57%. The most frequent manifestations in female patients were fatigue and cornea verticillata (50%, and tinnitus, vertigo and angiokeratoma (25%. Three patients had severe episodic abdominal pain attacks and proteinuria, and were misdiagnosed as familial Mediterranean fever. Conclusions: The prevalence of Fabry disease in selected CKD patients is in the range found among renal replacement therapy patients, but the disease is diagnosed at an earlier, treatable stage. These data support the ERBP recommendation to screen for Fabry disease in patients with CKD of unknown origin.

    Neuropsychiatric features and intellectual difficulties have been reported in studies of Darier's disease. Learning disabilities have never been reported or evaluated systematically in these patients. To assess the prevalence of learning disabilities in 76 patients with Darier's disease, and cognitive functioning in 19 of them. The data were collected by two methods: a questionnaire, as part of a larger study on the clinical characteristics of 76 patients; and neuropsychological measures for the assessment of learning disabilities in 19 of them. Thirty-one of the 76 patients reported learning disabilities (41%) and 56 (74%) reported a family history of learning disabilities. Significant differences were found between the 19 patients evaluated on cognitive tasks and a control group of 42 skilled learners on subtraction and multiplication tasks. Six (32%) of the 19 were identified as having reading difficulties and five (26%) exhibited low performance on the Concentration Performance Test. All patients had general cognitive ability in the average range. Findings suggest an association between Darier's disease and learning disabilities, a heretofore unreported association, pointing to the need to obtain personal and family history of such disabilities in order to refer cases of clinical concern for further study. © 2013 The Authors Journal of the European Academy of Dermatology and Venereology © 2013 European Academy of Dermatology and Venereology.

    Fibromyalgia (FM) is a syndrome characterized by chronic widespread pain and the presence of specific tender points. The prevalence of FM has been estimated at 2-7 % of the general global population. The presence of FM in several rheumatic diseases with a structural pathology has been reported as 11-30 %. The objectives of this study were to determine the prevalence of FM and to evaluate the possible relationship between FM existence and disease activity among rheumatic diseases. The study group included 835 patients--197 rheumatoid arthritis (RA), 67 systemic lupus erythematosus (SLE), 119 ankylosing spondylitis (AS), 238 osteoarthritis (OA), 14 familial Mediterranean fever (FMF), 53 Behçet's disease (BD), 71 gout, 25 Sjögren's syndrome (SS), 20 vasculitis, 29 polymyalgia rheumatica (PMR), and two polymyositis (PM)--with or without FM. Recorded information included age, gender, laboratory parameters, presence of fatigue, and disease activity indexes. The prevalence of FM in patients with rheumatologic diseases was found to be 6.6 % for RA, 13.4 % for SLE, 12.6 % for AS, 10.1 % for OA, 5.7 % for BD, 7.1 % for FMF, 12 % for SS, 25 % for vasculitis, 1.4 % for gout, and 6.9 % for PMR. One out of two patients with PM was diagnosed with FM. Some rheumatologic cases (AS, OA) with FM were observed mostly in female patients (p = 0.000). Also, there were significant correlations between disease activity indexes and Fibromyalgia Impact Questionnaire scores for most rheumatologic patients (RA, AS, OA, and BD) (p diseases, and its recognition is important for the optimal management of these diseases. Increased pain, physical limitations, and fatigue may be interpreted as increased activity of these diseases, and a common treatment option is the prescription of higher doses of biologic agents or corticosteroids. Considerations of the FM component in the management of rheumatologic diseases increase the likelihood of the success of the treatment.

    2016-07-01

    Full Text Available Background: The recently postulated disease spreading hypothesis has gained much attention, especially for Parkinson’s disease (PD. The various nonmotor symptoms (NMS in neurodegenerative diseases would be much better explained by this hypothesis than by the degeneration of disease-specific cell populations. Motor neuron disease (MND is primarily known as a group of diseases with a selective loss of motor function. Recent evidence, however, suggests disease spreading into nonmotor brain regions also in MND. The aim of this study was to comprehensively detect NMS in patients suffering from MND.Methods: We used a self-rating questionnaire including 30 different items of gastrointestinal, autonomic, neuropsychiatric and sleep complaints (NMSQuest which is an established tool in PD patients. 90 MND patients were included and compared to 96 controls.Results: In total, MND patients reported significantly higher NMS scores (median: 7 points in comparison to controls (median: 4 points. Dribbling, impaired taste/smelling, impaired swallowing, weight loss, loss of interest, sad/blues, falling and insomnia were significantly more prevalent in MND patients compared to controls. Interestingly excessive sweating was more reported in the MND group. Correlation analysis revealed an increase of total NMS score with disease progression.Conclusions: NMS in MND patients seemed to increase with disease progression which would fit with the recently postulated disease spreading hypothesis. The total NMS score in the MND group significantly exceeded the score for the control group, but only 8 of the 30 single complaints of the NMSQuest were significantly more often reported by MND patients. Dribbling, impaired swallowing, weight loss and falling could primarily be connected to motor neuron degeneration and declared as motor symptoms in MND.

    Celiac disease, one of the best-known autoimmune human leukocyte antigen-dependent disorders, has a relatively increased prevalence in first-degree relatives. To determine the prevalence of celiac disease in siblings of patients with confirmed celiac disease. Siblings of confirmed celiac disease patients in our center were identified and enrolled in this study. Their serum immunoglobulin A and tissue transglutaminase antibody-enzyme-linked immunosorbent assay (anti-tissue transglutaminase, immunoglobulin A, and immunoglobulin G) were measured and multiple endoscopic duodenal biopsy specimens were obtained with parental consensus. Celiac disease was confirmed by observation of characteristic histological changes. A total of 49 children (male, 29; female, 20; age, 2-16 years) with confirmed celiac disease in a pediatric gastroenterology ward were studied from 1999 to 2006. We found 30 siblings (female, 16) all shared in both parents. The only measurement available was for immunoglobulin A tissue transglutaminase antibody. A duodenal biopsy was performed in all 30 siblings. Clinical findings such as abdominal pain, fatigue, growth retardation and diarrhea were found in 53.3% of the completely studied siblings, and positive serology without histological changes was identified in four cases. Both serology and biopsy (confirmed new cases) were positive in 2 of the 30 siblings. High prevalence of celiac disease among siblings of patients with confirmed celiac disease necessitates serologic screening (and confirmatory biopsy if indicated) in families having celiac disease. It is advantageous to diagnose the disease as soon as possible because early diagnosis and diet intervention may prevent serious complications such as growth retardation, short stature, chronic diarrhea, and malignancy.

    Some patients with hyperthyroid Graves' disease have increased serum T3 and normal or even low serum T4 levels during treatment with antithyroid drugs. These patients with elevated serum T3 to T4 ratios rarely have a remission of their hyperthyroidism. The aim of this study was to investigate thyroid iodine metabolism in such patients, whom we termed T3-predominant Graves' disease. Mean thyroid radioactive iodine uptake was 51.0 +/- 18.1% ( +/- SD) at 3 h, and it decreased to 38.9 +/- 20.1% at 24 h in 31 patients with T3-predominant Graves' disease during treatment. It was 20.0 +/- 11.4% at 3 h and increased to 31.9 +/- 16.0% at 24 h in 17 other patients with hyperthyroid Graves' disease who had normal serum T3 and T4 levels and a normal serum T3 to T4 ratio during treatment (control Graves' disease). The activity of serum TSH receptor antibodies was significantly higher in the patients with T3-predominant Graves' disease than in control Graves' disease patients. From in vitro studies of thyroid tissue obtained at surgery, both thyroglobulin content and iodine content in thyroglobulin were significantly lower in patients with T3-predominant Graves' disease than in the control Graves' disease patients. Thyroid peroxidase (TPO) activity determined by a guaiacol assay was 0.411 +/- 0.212 g.u./mg protein in the T3-predominant Graves' disease patients, significantly higher than that in the control Graves' disease patients. Serum TPO autoantibody levels determined by immunoprecipitation also were greater in T3-predominant Graves' disease patients than in control Graves' disease patients. Binding of this antibody to TPO slightly inhibited the enzyme activity of TPO, but this effect of the antibody was similar in the two groups of patients

    Full Text Available Electronic patient records remain a rather unexplored, but potentially rich data source for discovering correlations between diseases. We describe a general approach for gathering phenotypic descriptions of patients from medical records in a systematic and non-cohort dependent manner. By extracting phenotype information from the free-text in such records we demonstrate that we can extend the information contained in the structured record data, and use it for producing fine-grained patient stratification and disease co-occurrence statistics. The approach uses a dictionary based on the International Classification of Disease ontology and is therefore in principle language independent. As a use case we show how records from a Danish psychiatric hospital lead to the identification of disease correlations, which subsequently can be mapped to systems biology frameworks.

    Because of the increasing number of patients, chronic kidney disease (CKD) has become a significant public health problem. As kidney function decreases, it is necessary to introduce certain dietary modifications. The aim was to investigate what is the appropriate approach to diet of CKD patients, which could contribute to slowing down progression of the disease. Dietary recommendations are individual for each patient, but also vary in the same patient depending on the stage of disease progression because special attention must be paid to appropriate intake of macronutrients (protein, carbohydrates and fats), micronutrients (sodium, potassium, calcium, phosphorus, zinc, selenium, various vitamins), and water. In newly diagnosed patients, it is necessary to assess their nutritional status and energy requirements. It has been shown that protein-energy malnutrition, muscle loss and cachexia are strong predictors of mortality in CKD. Comparing different dietary approaches in everyday life of patients suffering from CKD, it was found that the most effective diet is Mediterranean food style. Studies confirm that Mediterranean diet has a preventive effect on renal function and reduces progression of the disease. Preventive measures, correct identification and early intervention can increase survival of patients and improve their quality of life. Mediterranean diet tailored to individual stages of CKD has been confirmed as the best choice in CKD patients.

    Sexually transmitted diseases are still highly prevalent worldwide and represent an important public health problem. Psychiatric patients are at increased risk of sexually transmitted diseases but there are scarce published studies with representative data of this population. We sought to estimate the prevalence and correlates of self-reported sexually transmitted diseases among patients with mental illnesses under care in a national representative sample in Brazil (n=2145). More than one quarter of the sample (25.8%) reported a lifetime history of sexually transmitted disease. Multivariate analyses showed that patients with a lifetime sexually transmitted disease history were older, had history of homelessness, used more alcohol and illicit drugs, suffered violence, perceived themselves to be at greater risk for HIV and had high risk sexual behavioral: practised unprotected sex, started sexual life earlier, had more than ten sexual partners, exchanged money and/or drugs for sex and had a partner that refused to use condom. Our findings indicate a high prevalence of self-reported sexually transmitted diseases among psychiatric patients in Brazil, and emphasize the need for implementing sexually transmitted diseases prevention programs in psychiatric settings, including screening, treatment, and behavioral modification interventions.

    The aim of our survey was to record the experiences of hospitalised patients with respiratory diseases in order to create a more patient-friendly department. Our study included 609 patients (response rate 70%) with a median age of 64 years (range 13-91) who were discharged from the Department of Thoracic Medicine, Haukeland University Hospital in October 1991, 1992, 1994, 1995 and 1996. 268 patients had obstructive lung disease, 82 had lung cancer. They answered a questionnaire with 24 questions. Patient reception to the ward and staff knowledge of the patients' illnesses, were for the physicians rated as good or better by 92% and 79% and for the nurses by 94% and 70% respectively. 16% of the patients experienced insecurity, 17% anxiety, 12% helplessness, 9% loneliness and 12% little say in the decision making process. Trend factors for these emotional experiences were female sex, old age, obstructive lung disease and long stay in hospital. Patients aged 50 to 69 years and patients with lung cancer had the lowest rate of negative emotional experiences. Despite staff awareness of the prevalence and of the patients' emotional experiences and the risk factors involved, there was no clear reduction of negative experiences in the later surveys compared to the first survey. Patients in a university hospital with respiratory diseases showed unchanged experiences of health care and personal emotions in repeated surveys over a period of five years.

    The size of the perfusion defect was assessed from a quantitative analysis of exercise thallium-201 images. Quantitative analysis was determined by measuring the area and the perimeter of the perfusion defect and expressing it as a percentage of the total left ventricular area or perimeter in three projections. Using this technique, we studied 50 patients with one-vessel disease of 50% or greater diameter narrowing. The planimetric and the perimetric methods correlated well (p<0.001, r=0.97). Of the 11 patients with less than 70% diameter narrowing, only one patient had abnormal exercise thallium-201 images. Of the remaining 39 patients with 70% or greater diameter narrowing, 35 had abnormal exercise images. The defects were larger in patients with left anterior descending coronary artery disease (33 +/- 10%; mean +/- SD by perimetry) than in patients with left circumflex coronary artery disease (19 +/- 14%, p<0.01) or right coronary artery disease (17 +/- 11%, p<0.01). There was also significant variation in the sizes of the defects in the three projections in patients with left circumflex and right coronary artery disease, but not in patients with left anterior descending coronary artery disease. Patients with left anterior descending coronary artery disease with collaterals had smaller defects than their counterparts without collaterals

    BACKGROUND: While increased plasma cholesterol is a well-established cardiovascular risk factor in the general population, this is not so among patients with chronic renal disease. We hypothesized that the transvascular lipoprotein transport, in addition to the lipoprotein concentration in plasma......, determines the degree of atherosclerosis among patients with chronic renal disease. METHODS: We used an in vivo method for measurement of transvascular transport of low-density lipoprotein (LDL) in 21 patients with chronic renal disease and in 42 healthy control patients. Autologous 131-iodinated LDL...... was reinjected intravenously, and the 1-hour fractional escape rate was taken as index of transvascular transport. RESULTS: Transvascular LDL transport tended to be lower in patients with chronic renal disease than in healthy control patients [3.3 (95% CI 2.4-4.2) vs. 4.2 (3.7-4.2)%/hour; NS]. However...

    Patients with advanced liver disease have an increased risk of complications, compared to healthy patients when they undergo a surgical procedure. This risk is related to the type of surgery, to the type of anesthetic used, and to the severity of the underlying liver disease. Several risk factors for liver disease should be identified prior to a procedure. Those with advanced disease should undergo specific pre-surgical diagnostic tests. The Child Pugh score, and the MELD score, are very useful to establish the surgical risk in individuals with liver disease. The Child-Pugh score is a very useful tool that correlates closely to morbidity and mortality in patients with liver disease. Mortality rates in these patients undergoing major surgery is 10, 30 and 82% for Child-Pugh scores A, B and C respectively. In order to optimize the patient's condition before surgery, a complete evaluation and management of conditions such as jaundice, coagulopathy, ascites, electrolyte abnormalities, renal insufficiency and encephalopathy must be performed. This approach helps to reduce the complication rate in these individuals

    Pompe disease is a rare treatable glycogen storage disease with in adults - a limb-girdle muscle weakness. Muscle biopsy may fail to show the typical vacuolar myopathy. We asked if we had un-diagnosed patients with Pompe disease in western Sweden. We searched the muscle biopsy registry during the time period 1986 until 2006 including 3665 biopsies and included patients at our Neuromuscular Center with unspecified myopathy or limb-girdle muscular dystrophy. The dry blood spot test was used to identify patients with Pompe disease. A total of 82 patients (46 from the biopsy register and 36 from our center) were seen and dry blood spot test was obtained. No patient with Pompe disease was found. The dry blood spot test was low in three cases (11, 16, and 18% of normal) but a second blood sample showed a normal result based on GAA enzyme activity in lymphocytes in all three patients. In one patient with low normal result of the analysis in lymphocytes a genetic test showed no pathogenic mutations. Further investigation gave a definite diagnose of another myopathy in 12 patients. The prevalence of Pompe disease in western Sweden (3 in 1.27 million or 0.24 per 100.000 inhabitants) is lower than in the Netherlands and New York. Re-evaluation of patients with myopathies but without definite diagnosis is rewarding since 12 of 82 patients in our study had a definite molecular diagnosis after workup. © 2015 John Wiley & Sons A/S.

    2014-11-01

    Full Text Available Chronic Kidney disease (CKD is a pressing public health burden occurring in about 10% of the population. The majority of them die before reaching End Stage Renal Disease (ESRD due to cardiovascular disease (CVD. Hypertension (HTN and anaemia are two reversible factors for progression of CKD. Besides asymptomatic coronary artery disease, the electrolyte abnormalities such as hyperkalaemia and hypocalcaemia also subject these patients to sudden cardiac death. This study is aimed at to see the changes in electrocardiogram (ECG in hospitalized predialytic CKD patients due to these abnormalities. Methods: This is a 6 months cross-sectional study carried out at Chittagong Medical College Hospital in Chittagong, Bangladesh. 50 patients with stages 3, 4 and 5 CKD were recruited from the Nephrology and Medicine wards. Patients with prior history of coronary artery disease, cardiomyopathy, valvular heart disease and dialysis were excluded. All had their standard 12–lead electrocardiogram (ECG recorded and various findings were critically studied and interpreted independently by two consultant physicians including a cardiologist. Data analysis was done using SPSS version 19. Results: LVH (left ventricular hypertrophy (66%, LAE (left atrial enlargement (30% and unrecognized myocardial infarction (28% were very common ECG abnormalities in our predialytic CKD patients. HTN, anaemia, late presentation, and male gender appear to be associated with ECG abnormalities. Though 28 patients (56% were hyperkalaemic only 9 patients (38% of them had tall tented T wave in ECG. Conclusion: Detection of HTN and anaemia in male predialytic CKD patients will arouse suspicion which will help in early detection of cardiac outcome by ECG abnormality which will help in taking treatment strategy in resource limited country.

    Full Text Available Cardiovascular disease is the main cause of death among patients with end-stage renal disease (ESRD. The present study was undertaken to identify the main cardiovascular diseases and their risk factors in 160 patients with ESRD on hemodialysis (HD in Brazil. Their mean age was 47 ± 39 years. The main risk factors for cardiovascular diseases were arterial hypertension (89.4%, dyslipidemia (78.3%, low high-density lipoprotein levels (84.2% and low physical activity (64.1%. Family history of coronary insufficiency and high low-density lipoprotein levels were significantly associated with coronary artery disease (P = 0.005 and P = 0.029, respectively. Sedentary life style, diabetes mellitus, secondary hyperparathyroidism and hyperglycemia also showed a significant association with the underlying vascular disease (P = 0.017, P = 0.039, P = 0.037 and P = 0.030, respectively. Hypercalcemia, hypertension and black race were factors significantly associated with left ventricular systolic dysfunction (P = 0.01, P = 0.0013 and P = 0.024, respectively. Our study shows that the most prevalent cardiovascular diseases in patients with ESRD were left ventricular hypertrophy, atherosclerotic disease, valvular disease and coronary artery disease. Hypertension and dyslipidemia were the common risk factors associated with cardiovascular diseases. The present study was undertaken to identify the main cardiovascular diseases and their risk factors in 160 patients with ESRD on HD in a single center in Brazil.

    Burn shock, a complex process, which develops following burn leads to severe and unique derangement of cardiovascular function. Patients with preexisting comorbidities such as cardiovascular diseases may be more susceptible. We therefore sought to examine the impact of preexisting cardiovascular disease on burn outcomes. A retrospective analysis of patients admitted to a regional burn center from 2002 to 2012. Independent variables analyzed included basic demographics, burn mechanism, presence of inhalation injury, TBSA, pre-existing comorbidities, and length of ICU/hospital stay. Bivariate analysis was performed and Poisson regression modeling was utilized to estimate the incidence of being in the ICU and mortality. There were a total of 5332 adult patients admitted over the study period. 6% (n=428) had a preexisting cardiovascular disease. Cardiovascular disease patients had a higher mortality rate (16%) compared to those without cardiovascular disease (3%, pwill likely be a greater number of individuals at risk for worse outcomes following burn. This knowledge can help with burn prognostication. Copyright © 2017 Elsevier Ltd and ISBI. All rights reserved.

    AIM: To assess the combined effect of disease phenotype, smoking and medical therapy [steroid, azathioprine (AZA), AZA/biological therapy] on the probability of disease behavior change in a Caucasian cohort of patients with Crohn’s disease (CD). METHODS: Three hundred and forty well-characterized, unrelated, consecutive CD patients were analyzed (M/F: 155/185, duration: 9.4 ± 7.5 years) with a complete clinical follow-up. Medical records including disease phenotype according to the Montreal classification, extraintestinal manifestations, use of medications and surgical events were analyzed retrospectively. Patients were interviewed on their smoking habits at the time of diagnosis and during the regular follow-up visits. RESULTS: A change in disease behavior was observed in 30.8% of patients with an initially non-stricturing, non-penetrating disease behavior after a mean disease duration of 9.0 ± 7.2 years. In a logistic regression analysis corrected for disease duration, perianal disease, smoking, steroid use, early AZA or AZA/biological therapy use were independent predictors of disease behavior change. In a subsequent Kaplan-Meier survival analysis and a proportional Cox regression analysis, disease location (P = 0.001), presence of perianal disease (P < 0.001), prior steroid use (P = 0.006), early AZA (P = 0.005) or AZA/biological therapy (P = 0.002), or smoking (P = 0.032) were independent predictors of disease behavior change. CONCLUSION: Our data suggest that perianal disease, small bowel disease, smoking, prior steroid use, early AZA or AZA/biological therapy are all predictors of disease behavior change in CD patients.

    This paper aims to explore the assessment of patients with rheumatologic diseases, especially rheumatoid arthritis (RA), before undergoing orthopedic surgery. Perioperative assessment ensures an early diagnosis of the patient's medical condition, overall health, medical co-morbidities, and the assessment of the risk factors associated with the proposed procedures. Perioperative assessment allows for proper postoperative management of complications and of the management of drugs such as disease-modifying anti-rheumatic drugs (DMARD) and anti-platelets, and corticosteroids. The assessment also supports follow up plans, and patient education. Perioperative assessment enables the discussion of the proposed treatment plans and the factors associated with them in each case among the different specialists involved to facilitate an appropriate early decision-making about the assessment and treatment of patients with rheumatologic diseases. It also enables the discussion of both condition and procedure with the patient to ensure a good postoperative care. The article identifies the components of perioperative medical evaluation, discusses perioperative management of co-morbidities and the management of specific clinical problems related to RA, systemic lupus erythematosus, the management of DMARDs, like methotrexate (MTX) and biologic therapies, prophylactic antibiotics, and postoperative follow up, including patient education and rehabilitation PMID:24062860

    Full Text Available CONTEXT: Celiac disease, one of the best-known autoimmune human leukocyte antigen-dependent disorders, has a relatively increased prevalence in first-degree relatives. OBJECTIVE: To determine the prevalence of celiac disease in siblings of patients with confirmed celiac disease. METHODS: Siblings of confirmed celiac disease patients in our center were identified and enrolled in this study. Their serum immunoglobulin A and tissue transglutaminase antibody-enzyme-linked immunosorbent assay (anti-tissue transglutaminase, immunoglobulin A, and immunoglobulin G were measured and multiple endoscopic duodenal biopsy specimens were obtained with parental consensus. Celiac disease was confirmed by observation of characteristic histological changes. RESULTS: A total of 49 children (male, 29; female, 20; age, 2-16 years with confirmed celiac disease in a pediatric gastroenterology ward were studied from 1999 to 2006. We found 30 siblings (female, 16 all shared in both parents. The only measurement available was for immunoglobulin A tissue transglutaminase antibody. A duodenal biopsy was performed in all 30 siblings. Clinical findings such as abdominal pain, fatigue, growth retardation and diarrhea were found in 53.3% of the completely studied siblings, and positive serology without histological changes was identified in four cases. Both serology and biopsy (confirmed new cases were positive in 2 of the 30 siblings. CONCLUSION: High prevalence of celiac disease among siblings of patients with confirmed celiac disease necessitates serologic screening (and confirmatory biopsy if indicated in families having celiac disease. It is advantageous to diagnose the disease as soon as possible because early diagnosis and diet intervention may prevent serious complications such as growth retardation, short stature, chronic diarrhea, and malignancy.

    Chronic obstructive pulmonary disease is the fourth leading cause of mortality worldwide. It is defined as a persistent airflow limitation usually progressive and not fully reversible to treatment. The diagnosis of chronic obstructive pulmonary disease and severity of disease is confirmed by spirometry. Chronic obstructive pulmonary disease produces electrical changes in the heart which shows characteristic electrocardiogram pattern. The aim of this study was to observe and evaluate diagnostic values of electrocardiogram changes in chronic obstructive pulmonary disease patients with no other comorbidity. We analyzed 110 electrocardiogram findings in clinically stable chronic obstructive pulmonary disease patients and evaluated the forced expiratory volume in the first second, ratio of forces expiratory volume in the first second to the fixed vital capacity, chest radiographs and electrocardiogram changes such as p wave height, QRS axis and voltage, right bundle branch block, left bundle branch block, right ventricular hypertrophy, T wave inversion in leads V1-V3, S1S2S3 syndrome, transition zone in praecordial lead and QT interval. We found electrocardiogram changes in 64% patients, while 36% had normal electrocardiogram. The most frequent electrocardiogram changes observed were transition zone (76.36%) low QRS (50%) and p pulmonale (14.54%). Left axis deviation was observed in 27.27% patients. Diagnostic values of electrocardiogram in patients with chronic obstructive pulmonary disease suggest that chronic obstructive pulmonary disease patients should be screened electrocardiographically in addition to other clinical investigations.

    Our objective in this study was to evaluate the nutritional status and to identify clinical, psychosocial, and nutritional factors contributing to malnutrition in Korean patients with Parkinson's disease. We used a descriptive, cross-sectional study design. Of 102 enrolled patients, 26 (25.5%) were malnourished and 27 (26.5%) were at risk of malnutrition based on Mini-Nutritional Assessment scores. Malnutrition was related to activity of daily living score, Hoehn and Yahr stage, duration of levodopa therapy, Beck Depression Inventory and Spielberger's Anxiety Inventory scores, body weight, body weight at onset of Parkinson's disease, and body mass index. On multiple logistic regression analysis, anxiety score, duration of levodopa therapy, body weight at onset of Parkinson's disease, and loss of body weight were significant factors predicting malnutrition in Parkinson's disease patients. Therefore, nutritional assessment, including psychological evaluation, is required for Parkinson's disease patients to facilitate interdisciplinary nutritional intervention for malnourished patients. © 2014 John Wiley & Sons Australia, Ltd.

    Patients with renal disease typically have severely calcified peripheral arterial disease. As a result, this population may have worse clinical outcomes following endovascular intervention compared to patients without renal insufficiency. Clinical trials typically exclude this patient population. Analysis of the CONFIRM I-III registries revealed 1105 patients with renal disease (1777 lesions) and 1969 patients without renal disease (2907 lesions) who underwent orbital atherectomy. This subanalysis compared the composite procedural complication rate including dissection, perforation, slow flow, vessel closure, spasm, embolism, and thrombus formation in patients with and without renal disease. Patients with renal disease had a higher prevalence of diabetes (Patherectomy resulted in similar low rates of procedural complications in the renal disease group compared with the non-renal disease group despite more unfavorable baseline clinical and lesion characteristics in the renal disease group.

    Despite the chronic and relapsing nature of inflammatory bowel diseases (IBD), at least 30% to 45% of the patients are noncompliant to treatment. IBD patients often seek information about their disease. To examine the association between information-seeking activity and treatment compliance among IBD patients. To compare information sources and concerns between compliant and noncompliant patients. We used data from the Swiss IBD cohort study, and from a qualitative survey conducted to assess information sources and concerns. Crude and adjusted odds ratios (OR) for noncompliance were calculated. Differences in the proportions of information sources and concerns were compared between compliant and noncompliant patients. A total of 512 patients were included. About 18% (n = 99) of patients were reported to be noncompliant to drug treatment and two-thirds (n = 353) were information seekers. The OR for noncompliance among information seekers was 2.44 (95%CI: 1.34-4.41) after adjustment for confounders and major risk factors. General practitioners were 15.2% more often consulted (p = 0.019) among compliant patients, as were books and television (+13.1%; p = 0.048), whereas no difference in proportions was observed for sources such as internet or gastroenterologists. Information on tips for disease management were 14.2% more often sought among noncompliant patients (p = 0.028). No difference was observed for concerns on research and development on IBD or therapies. In Switzerland, IBD patients noncompliant to treatment were more often seeking disease-related information than compliant patients. Daily management of symptoms and disease seemed to be an important concern of those patients.

    There is neither proven effective prevention for Alzheimer disease nor a cure for patients with this disorder. Nevertheless, a spectrum of biopsychosocial therapeutic measures is available for slowing progression of the illness and enhancing quality of life for patients. These measures include a range of educational, psychological, social, and behavioral interventions that remain fundamental to effective care. Also available are a number of pharmacologic treatments, including prescription medications approved by the US Food and Drug Administration for Alzheimer disease, "off-label" uses of medications to manage target symptoms, and controversial complementary therapies. Physicians must make the earliest possible diagnosis to use these treatments most effectively. Physicians' goals should be to educate patients and their caregivers, to plan long-term care options, to maximally manage concurrent illnesses, to slow and ameliorate the most disabling symptoms, and to preserve effective functioning for as long as possible. The authors review the various current treatments for patients with Alzheimer disease.

    2013-06-01

    It is estimated that there are over ten million rare disease patients in China currently. Due to a lack of effective drugs and reimbursement regulations for medical expenses the diseases bring most patients enormous physical suffering and psychological despair. Past experience in other countries such as the United States, Japan, and the European Union have shown that legislation is the critical step to improve the miserable situation of rare disease patients. Laws and regulations for rare diseases in these countries prescribe a series of incentives for research and development of orphan drugs which turn out to obviously allow these drugs to flourish. Legislation has also established a drug reimbursement system to reduce the medical burden of the patients. These measures effectively protect the rights and interests of patients with rare diseases. In China, legislation for rare diseases has begun to attract the attention of authorities. It is anticipated that relevant laws and regulations will be established as early as possible to provide safeguards for rare disease patients in China.

  11. Immune defects in active mycobacterial diseases in patients with primary immunodeficiency diseases (PIDs

    Full Text Available Natural human immunity to the mycobacteria group, including Mycobacterium tuberculosis, Bacille Calmette-Guérin (BCG or nontuberculous mycobacteria (NTM, and/or Salmonella species, relies on the functional IL-12/23-IFN-γ integrity of macrophages (monocyte/dendritic cell connecting to T lymphocyte/NK cells. Patients with severe forms of primary immunodeficiency diseases (PIDs have more profound immune defects involving this impaired circuit in patients with severe combined immunodeficiencies (SCID including complete DiGeorge syndrome, X-linked hyper IgM syndrome (HIGM (CD40L mutation, CD40 deficiency, immunodeficiency with or without anhidrotic ectodermal dysplasia (NEMO and IKBA mutations, chronic granulomatous disease (CGD and hyper IgE recurrent infection syndromes (HIES. The patients with severe PIDs have broader diverse infections rather than mycobacterial infections. In contrast, patients with an isolated inborn error of the IL-12/23-IFN-γ pathway are exclusively prone to low-virulence mycobacterial infections and nontyphoid salmonella infections, known as Mendelian susceptibility to the mycobacterial disease (MSMD phenotype. Restricted defective molecules in the circuit, including IFN-γR1, IFN-γR2, IL-12p40, IL-12R-β1, STAT-1, NEMO, IKBA and the recently discovered CYBB responsible for autophagocytic vacuole and proteolysis, and interferon regulatory factor 8 (IRF8 for dendritic cell immunodeficiency, have been identified in around 60% of patients with the MSMD phenotype. Among all of the patients with PIDs referred for investigation since 1985, we have identified four cases with the specific defect (IFNRG1 for three and IL12RB for one, presenting as both BCG-induced diseases and NTM infections, in addition to some patients with SCID, HIGM, CGD and HIES. Furthermore, manifestations in patients with autoantibodies to IFN-γ (autoAbs-IFN-γ, which is categorized as an anticytokine autoantibody syndrome, can resemble the relatively

    Full Text Available Although Alzheimer's disease (AD primarily manifests as cognitive deficits, the implicit sensorimotor processes that underlie social interactions, such as automatic imitation, seem to be preserved in mild and moderate stages of the disease, as is the ability to communicate with other persons. Nevertheless, when AD patients face more challenging tasks, which do not rely on automatic processes but on explicit voluntary mechanisms and require the patient to pay attention to external events, the cognitive deficits resulting from the disease might negatively affect patients’ behaviour. The aim of the present study was to investigate whether voluntary motor imitation, i.e. a volitional mechanism that involves observing another person’s action and translating this perception into one’s own action, was affected in patients with Alzheimer’s disease. Further, we tested whether this ability was modulated by the nature of the observed stimulus by comparing the ability to reproduce the kinematic features of a human demonstrator with that of a computerized-stimulus. AD patients showed an intact ability to reproduce the velocity of the observed movements, particularly when the stimulus was a human agent. This result suggests that high-level cognitive processes involved in voluntary imitation might be preserved in mild and moderate stages of AD and that voluntary imitation abilities might benefit from the implicit interpersonal communication established between the patient and the human demonstrator.

    Treatment recommendations for patients with upper abdominal Stage IIIA Hodgkin's (III1A) disease have varied widely. The current study reports on a combined institutional retrospective review of 85 patients with surgically staged III1A Hodgkin's disease. Twenty-two patients received combined modality therapy (CMT), 36 patients were treated initially with total nodal irradiation (TNI), and 27 with mantle and para-aortic radiotherapy (MPA). Patients treated with CMT had an actuarial 8-year freedom from relapse (FFR) of 96% as compared to a FFR of 51% in TNI treated patients (p = 0.002), and a FFR of 54% in MPA treated patients (p = 0.004). Of the 11 relapses in MPA treated patients, 7 had a component of their failure in the untreated pelvic or inguinal nodes. The patients treated with CMT had an 8-year actuarial survival of 100% as compared to 79% in TNI treated patients (p = 0.055) and 78% in patients treated with MPA (p = 0.025). Histology and the number of splenic nodules were the most important prognostic variables. Patients with MC/LD histology and greater than or equal to 5 splenic nodules have a high risk of relapse (10/13) when treated with radiation alone (TNI or MPA). We recommend CMT for this group of patients. Patients with NS/LP histology and 1-4 splenic nodules represent a favorable subset of Stage III1A patients. Only 4/21 patients have relapsed and all 21 patients are currently alive without disease regardless of treatment. We currently feel that patients with Stage III1A Hodgkin's disease with NS/LP histology and splenic disease limited to 1-4 nodules are good candidates for MPA as an alternative to TNI or CMT

    Full Text Available PURPOSE: To characterize patients with neoplastic pericardial disease diagnosed by clinical presentation, complementary test findings, and the histological type of tumor. METHODS: Twenty-six patients with neoplastic pericardial disease were retrospectively analyzed. RESULTS: Clinical manifestations and abnormalities in chest roentgenograms and electrocardiograms were frequent, but were not specific. Most patients underwent surgery. There was a high positivity of the pericardial biopsy when associated with the cytological analysis of the pericardial liquid used to determine the histological type of the tumor, particularly when the procedure was performed with the aid of pericardioscopy. CONCLUSION: The correct diagnosis of neoplastic pericardial disease involves suspicious but nonspecific findings during clinical examination and in screen tests. The suspicious findings must be confirmed through more invasive diagnostic approaches, in particular pericardioscopy with biopsy and cytological study.

    Patients with intractable disease require long-term treatment and experience repeated bouts of progressive symptoms and resolutions, which cause them severe suffering. The aim of this study was to elucidate the concepts of self-transcendence and subjective well-being in patients with intractable disease. Forty-four patients with intractable disease (men/women: 22/22) participated. The diseases of the participants were classified into five systems: (i) neural/muscle system; (ii) digestive system; (iii) immunity/blood system; (iv) visual system; and (v) bone/joint system. The controls were 1854 healthy individuals (men/women: 935/869). Participants completed the Self-Transcendence Scale (STS) and the Japanese version of the World Health Organization-Subjective Inventory. The Japanese version of the Mini-International Neuropsychiatric Interview was also used for the intractable disease group. Analysis of covariance found a significant increase in STS score among the intractable disease group (P self-transcendence. The results also showed that there was a strong correlation between self-transcendence and respondents' subjective well-being. Our results suggest that patients with life-changing intractable disease can have a high level of self-transcendence, which may lead them to regain mental well-being, and increase their psychological health even in situations that cause physical and mental suffering. © 2011 The Authors.

    To assess health care costs associated with Cushing disease and to determine changes in overall and comorbidity-related costs after surgical treatment. In this retrospective cohort study, patients with Cushing disease were identified from insurance claims databases by International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) codes for Cushing syndrome (255.0) and either benign pituitary adenomas (227.3) or hypophysectomy (07.6×) between 2004 and 2008. Each patient with Cushing disease was age- and sex-matched with 4 patients with nonfunctioning pituitary adenomas and 10 population control subjects. Comorbid conditions and annual direct health care costs were assessed within each calendar year. Postoperative changes in health care costs and comorbidity-related costs were compared between patients presumed to be in remission and those with presumed persistent disease. Of 877 identified patients with Cushing disease, 79% were female and the average age was 43.4 years. Hypertension, diabetes mellitus, and hyperlipidemia were more common among patients with Cushing disease than in patients with nonfunctioning pituitary adenomas or in control patients (PCushing disease had significantly higher total health care costs (2008: $26 440 [Cushing disease] vs $13 708 [nonfunctioning pituitary adenomas] vs $5954 [population control], Pdisease-related costs with remission. A significant increase in postoperative health care costs was observed in those patients not in remission. Patients with Cushing disease had more comorbidities than patients with nonfunctioning pituitary adenomas or control patients and incurred significantly higher annual health care costs; these costs decreased after successful surgery and increased after unsuccessful surgery.

    Full Text Available Admission By analyzing the available scientific literature, it is possible to define ischemic heart disease as a set of disease symptoms that are a consequence of a chronic state of imbalance between the ability to supply nutrients and oxygen and the real need of myocardial cells for these substances. Adapting life-style behaviors to healthy living is a priority to prevent the onset and development of cardiovascular disease, especially ischemic heart disease, Purpose of research The aim of the study is to determine the health behavior of patients with ischemic heart disease. Materials and methods The study was conducted from 01.08.2015 to 28.12.2015 in a group of 35 people (15 women and 20 men. The research method used in the work is a diagnostic survey, the research technique used was a survey of its own author. Conclusions By analyzing the data collected, it is important to note that patients with coronary heart disease are often associated with health problems such as hypertension, diabetes and abnormal weight. The nutritional habits of the subjects studied can be described as abnormal, particularly the excessive intake of oily meat and too little fish intake. It has also been observed that most of the patients studied have familial predisposition to ischemic heart disease. Discussion Heart attacks occur mostly in people with obesity, diabetes and atherosclerosis. It is also closely related to ischemic heart disease. The health behaviors of patients suffering from Ischemic Heart Disease are moderately satisfactory and therefore the role of a nurse practitioner as a health educator is very difficult but essential in the prevention of ischemic heart disease.

    Chronic kidney disease (CKD) is associated with increased risk of cardiovascular disease. Electrocardiographic (ECG) abnormalities are common in CKD patients. However, there is variation in literature regarding frequency of ECG abnormalities in CKD patients and limited information in local population. Methods: The study design was cross-sectional in nature. All patients between ages of 20-80 years with CKD not previously on renal replacement therapy who were admitted to nephrology ward at a tertiary care facility over a 6-month period were included. All patients underwent 12 lead electrocardiograms (ECG). ECG abnormalities were defined based on accepted standard criteria. Results: Total number of patients included in the study was 124. Mean age of all patients was 49.9+-13.8 years, 106 (84.8%) had hypertension, 84 (70%) had diabetes mellitus, and 35 (29.9%) had known cardiovascular disease. Mean serum creatinine was 7.2+-3.4 mg/dl, mean eGFR was 10.6+-9.2 ml/min/1.73 m/sup 2/. Overall 78.4% of all CKD patients have one or more ECG abnormality. Left ventricular hypertrophy (40%), Q waves (27.2%), ST segment elevation or depression (23.4%), prolonged QRS duration (19.2%), tachycardia (17.6%) and left and right atrial enlargement (17.6%) were the most common abnormalities. Conclusion: ECG abnormalities are common in hospitalized CKD patients in local population. All hospitalized CKD patients should undergo ECG to screen for cardiovascular disease. (author)

    The best preoperative examination in Graves' disease with thyroid cancer still remains uncertain. The objectives of the present study were to investigate the prevalence of thyroid cancer in Graves' disease patients, and to identify the predictive factors and ultrasonographic features of thyroid cancer that may aid the preoperative diagnosis in Graves' disease. This retrospective study included 423 patients with Graves' disease who underwent surgical treatment from 2002 to 2012 at our institution. The clinical features and ultrasonographic findings of thyroid nodules were recorded. The diagnosis of thyroid cancer was determined according to the pathological results. Thyroid cancer was discovered in 58 of the 423 (13.7 %) surgically treated Graves' disease patients; 46 of those 58 patients had thyroid nodules, and the other 12 patients were diagnosed with incidentally discovered thyroid carcinomas without thyroid nodules. Among the 58 patients with thyroid cancer, papillary microcarcinomas were discovered in 50 patients, and multifocality and lymph node involvement were detected in the other 8 patients. Multivariate regression analysis showed younger age was the only significant factor predictive of metastatic thyroid cancer. Ultrasonographic findings of calcification and intranodular blood flow in thyroid nodules indicate that they are more likely to harbor thyroid cancers. Because the influencing factor of metastatic thyroid cancers in Graves' disease is young age, every suspicious nodule in Graves' disease patients should be evaluated and treated carefully, especially in younger patients because of the potential for metastasis.

    The aim of this work was to study cross-cultural variations in the impact of inflammatory bowel disease (IBD) on health-related quality of life by an international comparison of disease-related concerns. Item and factor scores on the Rating Form of Inflammatory Bowel Disease Patient Concerns and overall mean concern levels were compared by analysis of variance among 2002 IBD patients in eight countries. The overall level of concern varied from 51 out of 100 in Portugal to 19 in Sweden, with intermediate scores for Italy (43), Canada (40), United States (39), France (39), Austria (33), and Israel (25). Having surgery, an ostomy, the uncertain nature of the disease, and medication side effects were each rated among the first five in importance in six countries. Other items varied considerably. For example, concern regarding pain and suffering was high in Israel and low in Portugal, whereas concern over developing cancer was low in Italy. Concern over financial issues and access to high-quality health care were inversely associated with measures of national economic prosperity. 1) Cross-cultural comparisons of patient concerns related to IBD are feasible using translated scales. 2) Reporting tendencies vary greatly; within Europe, patients from southern countries report greater overall concern. 3) The complications and the variable evolution of disease elicit general concern, but the importance of specific issues varies among countries. 4) The reasons for national differences may have social, cultural, and/or economic determinants with relevance to the patient-physician relationship, patient education, and therapeutic decision making.

    Behcet's disease is a chronic relapsing disorder of unknown etiology characterized by oral aphthous ulcerations, uveitis, genital ulcerations and bone lesions. A variety of other signs including polyarthritis, vascular conditions (blood vessel occlusions and aneurysms), epididymitis, gastrointestinal, pulmonary and heart lesions may also occur. Central nervous system (CNS) involvement is reported in 10-49 % of cases and it is the first symptom of the disease in 5 % of subjects. The neuro-Behcet's syndrome may appear as a brainstem syndrome, and an organic confusional syndrome or dementia. cranial hypertension, mostly related to cerebral venus thrombosis, is also present in neuro-Behcet's disease and its incidence is reported in up to 10 % of Behcet's patients. MRI is reportedly the most sensitive neuroradiological approach to detect the focal lesions related to neuro-Behcet disease and several single cases or series of Behcet's patients with neurologic sings have been examined with MRI. They used MRI to investigate CNS involvement in Behcet's disease patients with and without previous neurologic sings. MRI was carried out on 17 patients with ocular Behcet's disease without neurological symptoms to assess the possible subclinical involvement of the CNS. PD and T2-weighted hypersignal foci were demonstrated in parietal, frontal, subcortical and periventricular white matter in 6 subjects. Neuroradiological abnormalities were found only in patients with complete disease and with the disease diagnosed more than 10 years earlier. Even though the pathogenesis of these neuroradiological abnormalities and their correlation with Behcet's disease remain to be clarified, their study suggests the possibility of subclinical CNS involvement in these patients, which may affect the therapeutic approach and their prognosis

    INTRODUCTION: After the introduction of L-dopa the mortality rate in Parkinson's disease (PD) patients has changed, but is still higher than in the background population. MATERIAL & METHODS: Mortality, age at death and cause of death in a group of PD patients compared with the background population....... In the background population the median age at death was 80.69 years for men and 84.37 years for women. The SMR for men was 1.92 and for women 2.47. Infections, in particular lung infections, and heart diseases were the most common causes of death. Seventy percent of the death certificates had PD as a diagnosis....... CONCLUSION: It is likely that several factors can influence the changed mortality of PD: more effective treatment, changing diagnostic practice, and inter-disease competition....

    Full Text Available Although rare in childhood, stroke may have a serious impact when it happens in this stage of life. Also, it may be the first sign of a systemic disease. We report 12 cases of patients with stroke treated in the Neuropediatrics Unit of Hospital de Clínicas de Porto Alegre (HCPA from March 1997 to March 2000. All patients, from term infants to 12-year-old children hospitalized in the Pediatrics Unit of HCPA, had clinical suspicion of stroke, which was later confirmed by radiological studies. Patient follow up ranged from 1 to 6 years (mean = 3.4 years. Presenting symptoms were hemiparesis in 9 patients, seizures in 7, deviation of labial commissure in 3, and loss of consciousness in 1. The increase in the number of cases of childhood stroke identified and later confirmed by noninvasive methods had helped in the determination of different ethiologies of stroke: the most frequent being hematologic, cardiac and genetic diseases. However, our study included 6 newborns with stroke whose ethiology was not identified. Seven children with seizures received phenobarbital. Six term infants had neonatal seizures secondary to stroke and restricted to the first 72 hours of life.

    Periodontal disease is one of the most frequent diseases affecting people all over the world. The relation between periodontal disease and diabetes mellitus raised the interest both of dentists and doctors treating metabolic diseases, as the two conditions influence one another. In our study, we analyzed a number of 75 patients with diabetes mellitus and periodontal disease that presented to the medical consultory for conditions of the dental maxillary system. The clinical study showed that periodontal disease and diabetes may affect young adults as well, still this pathological association more frequently appears after the age of 50. The disease was identified especially in the women living in urban area. The clinical examination of the dental maxillary system identified the presence of gingival ulcerations, dental calculus, gingival bleeding, radicular leftovers with anfractuous margins, fixed prostheses with an inappropriate cervical adjustment. Of the systemic diseases associated to periodontal disease and diabetes mellitus, there was observed that 66.66% of the patients also suffered from cardiovascular diseases (high blood pressure, ischemic cardiopathy, heart failure), and 37.33% suffered from obesity. The histopathological and immunohistochemical tests highlighted the presence of an inflammatory chronic, intense reaction, mainly formed of lymphocytes, plasmocytes, macrophages and granulocytes, heterogeneously disseminated and alteration of the structure of marginal and superficial periodontium. The inflammatory reaction in the patients with periodontal disease and diabetes was more intense than in the patients with periodontal disease without diabetes.

    Previous studies have reported that patients with Parkinson's disease (PD) have a favorable cardiometabolic risk profile. The aim of this study was to investigate the relationship between cardiometabolic risk factors and the duration of disease. One hundred and fifty patients with PD (56.7% men) were studied, measuring body mass index (BMI), waist circumference (WC), body fat percentage (BF%) by impedance, fasting glucose, serum lipids, and transaminases. In sex- and age-adjusted correlation models, duration of PD was inversely related to BMI (r = -0.20; P HDL) levels were positively correlated with disease duration (P HDL-cholesterol ratio was also inversely associated with duration of PD (P HDL levels and total HDL-cholesterol ratio were favorably associated with duration of PD. This factor may contribute to cardiometabolic protection in PD. The mechanisms underlying this association deserve further investigation. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Background/aimsCognitive impairment, which frequently occurs in patients with schizophrenia, bipolar disorder, Alzheimer’s disease, and Parkinson’s disease, has a significant impact on the daily lives of both patients and their family. Furthermore, since the medications used for cognitive enhancement have limited efficacy, the issue of cognitive enhancement still remains a clinically unsolved challenge.Sampling and methodsWe reviewed the clinical studies (published between 2007 and 2017 that focused on the efficacy of medications used for enhancing cognition in patients with schizophrenia, bipolar disorder, Alzheimer’s disease, and Parkinson’s disease.ResultsAcetylcholinesterase inhibitors and memantine are the standard treatments for Alzheimer’s disease and Parkinson’s disease. Some studies have reported selective cognitive improvement in patients with schizophrenia following galantamine treatment. Newer antipsychotics, including paliperidone, lurasidone, aripiprazole, ziprasidone, and BL-1020, have also been reported to exert cognitive benefits in patients with schizophrenia. Dopaminergic medications were found to improve language function in patients with Parkinson’s disease. However, no beneficial effects on cognitive function were observed with dopamine agonists in patients with schizophrenia. The efficacies of nicotine and its receptor modulators in cognitive improvement remain controversial, with the majority of studies showing that varenicline significantly improved the cognitive function in schizophrenic patients. Several studies have reported that N-methyl-d-aspartate glutamate receptor (NMDAR enhancers improved the cognitive function in patients with chronic schizophrenia. NMDAR enhancers might also have cognitive benefits in patients with Alzheimer’s disease or Parkinson’s disease. Raloxifene, a selective estrogen receptor modulator, has also been demonstrated to have beneficial effects on attention, processing

    Despite the significant advances in the medical management of inflammatory bowel disease over the last decade, surgery continues to play a major role in the management of pediatric Crohn's disease (CD). While adult and pediatric Crohn's disease may share many clinical characteristics, pediatric Crohn's patients often have a more aggressive phenotype, and the operative care given by the pediatric surgeon to the newly diagnosed Crohn's patient is very different in nature to the surgical needs of adult patients after decades of disease progression. Children also have the unique surgical indication of growth failure to consider in the overall clinical decision making. While surgery is never curative in CD, it has the ability to transform the disease process in children, and appropriately timed operations may have tremendous impact on a child's physical and mental maturation. This monograph aims to address the surgical care of Crohn's disease in general, with a specific emphasis on the surgical treatment of small intestinal and ileocecal involvement.

    Surgery in patients with sickle cell disease (SCD) has been associated with high morbidity and mortality. In recent years, a marked improvement in the safety of surgery and anesthesia in this high-risk group of patients has been witnessed; owing to the improvements in surgical and anesthetic care, greater awareness of pathophysiology of disease, proper perioperative preparation and attention to factors predisposing to vasoocclusive crises. However, this is not paralleled by similar improvement in countries where the disease is not prevalent. Greater population mobility in recent years makes recognition of surgical manifestations of the disease and awareness of perioperative management of sickle cell patients undergoing surgical interventions of paramount importance. This article aims to summarize steps towards safer surgery in patients with SCD. (author)

    Background/Aims To characterize ultrasonographic findings in papillary thyroid carcinoma (PTC) combined with Graves' disease. Methods Medical records and ultrasonographic findings of 1,013 patients with Graves' disease and 3,380 patients without Graves' disease were analyzed retrospectively. A diagnosis of PTC was based on a pathologic examination. Results The frequency of hypoechogenicity was lower in patients with PTC and Graves' disease than in patients with PTC alone (p Graves' disease was significantly higher than in those with PTC alone (p Graves' disease was characterized by more ill-defined borders and less frequency of overall calcification, punctate calcification, and heterogeneous echogenicity, although the difference was not statistically significant. Conclusions Our results suggest that patients with Graves' disease more frequently have atypical PTC findings on ultrasonography. PMID:20195406

    Full Text Available A significant problem in the dental medicine is pain alleviation. Many studies in the dental anesthesiology result in the production of new agents for locoregional anesthesia. Objective: This article aim to present the results of the last studies on the effect of the local anesthetics used in the oral surgery on patients with cardiovascular diseases. Material: A general review of the existing literature on the effect of the adrenaline, included as vasoconstrictor in the local anesthetics, used in patients with cardiovascular diseases is made. The benefits of vasoconstrictors for the quality of the anesthetic effect are proven. Conclusion: A small amount of adrenaline in the anesthetic solution does not result in complications development in patients with controlled cardiovascular diseases. Articaine is recommended agent of first choice for local anesthesia in the oral surgery.

    In celiac disease (CD), the gut is the typical manifestation site but atypical neurological presentations are thought to occur in 6 to 10% with cerebellar ataxia being the most frequent symptom. Most studies in this field are focused on patients under primary neurological care. To exclude such an observation bias, patients with biopsy proven celiac disease were screened for neurological disease. A total of 72 patients with biopsy proven celiac disease (CD) (mean age 51 +/- 15 years, mean disease duration 8 +/- 11 years) were recruited through advertisements. All participants adhered to a gluten-free diet. Patients were interviewed following a standard questionnaire and examined clinically for neurological symptoms. Medical history revealed neurological disorders such as migraine (28%), carpal tunnel syndrome (20%), vestibular dysfunction (8%), seizures (6%), and myelitis (3%). Interestingly, 35% of patients with CD reported of a history of psychiatric disease including depression, personality changes, or even psychosis. Physical examination yielded stance and gait problems in about one third of patients that could be attributed to afferent ataxia in 26%, vestibular dysfunction in 6%, and cerebellar ataxia in 6%. Other motor features such as basal ganglia symptoms, pyramidal tract signs, tics, and myoclonus were infrequent. 35% of patients with CD showed deep sensory loss and reduced ankle reflexes in 14%. Gait disturbances in CD do not only result from cerebellar ataxia but also from proprioceptive or vestibular impairment. Neurological problems may even develop despite strict adherence to a gluten-free diet. (c) 2009 Movement Disorder Society.

    Electronic patient records remain a rather unexplored, but potentially rich data source for discovering correlations between diseases. We describe a general approach for gathering phenotypic descriptions of patients from medical records in a systematic and non-cohort dependent manner. By extracting...... phenotype information from the free-text in such records we demonstrate that we can extend the information contained in the structured record data, and use it for producing fine-grained patient stratification and disease co-occurrence statistics. The approach uses a dictionary based on the International...

    Celiac disease is an intestinal immune mediated disorder, triggered by ingestion of gluten-containing diet in genetically susceptible individuals. The genetic pre-disposition is related to human leukocyte antigen (HLA) class II genes, especially HLA-DQ2 positive patients. The prevalence of celiac disease in high worldwide and it has been estimated to be 1-26% in Western countries. Many auto-immune diseases can be associated with celiac disease including auto-immune thyroid disease; hashimoto thyroiditis and grave's disease. The opposite also appears to be true, celiac disease is found on persons with auto-immune thyroid disorders at high rates than the general population. Celiac disease is also associated with other extraintestinal diseases other the auto-immune diseases like anemia, short stature, metabolic bone disease and others. Screening for celiac disease should be considered in patients with auto-immune thyroid disease, anemia, short stature and metabolic bone disease. The life-long adherence to gluten-free diet is the only cure in celiac disease and can improve the quality of patients life and prevent future complications. This report describes a case of Grave's disease, Iron deficiency anemia, Short stature, Osteopenia, diagnosed to have Celiac disease. (author)

    Full Text Available Background: Peripheral arterial disease is associated with adverse cardiovascular outcomes. As such, it is found that screening for peripheral arterial disease (PAD improves risk assessment. Thus, intensive risk factor modification and medical treatment in these patients are necessary. Objectives: The purpose of this study was to determine the prevalence of asymptomatic peripheral arterial disease in patients with concomitant coronary arterial disease. Methods: Asymptomatic peripheral arterial disease was investigated in 400 patients (60% males, 40% females, aged 59.7± 11.3 with a documented coronary arterial disease. Results: Among patients with documented CAD, 12% had asymptomatic PAD with the ABI ratio of less than 0.9. Conclusions: It is advisable to screen for PAD not only as a disease but also as a risk assessment method for atherosclerosis.

    Experimental evidence suggests the endogenous cannabinoid system may protect against colonic inflammation, leading to the possibility that activation of this system may have a therapeutic role in inflammatory bowel disease (IBD). Medicinal use of cannabis for chronic pain and other symptoms has been reported in a number of medical conditions. We aimed to evaluate cannabis use in patients with IBD. One hundred patients with ulcerative colitis (UC) and 191 patients with Crohn's disease (CD) attending a tertiary-care outpatient clinic completed a questionnaire regarding current and previous cannabis use, socioeconomic factors, disease history and medication use, including complimentary alternative medicines. Quality of life was assessed using the short-inflammatory bowel disease questionnaire. A comparable proportion of UC and CD patients reported lifetime [48/95 (51%) UC vs. 91/189 (48%) CD] or current [11/95 (12%) UC vs. 30/189 (16%) CD] cannabis use. Of lifetime users, 14/43 (33%) UC and 40/80 (50%) CD patients have used it to relieve IBD-related symptoms, including abdominal pain, diarrhoea and reduced appetite. Patients were more likely to use cannabis for symptom relief if they had a history of abdominal surgery [29/48 (60%) vs. 24/74 (32%); P=0.002], chronic analgesic use [29/41 (71%) vs. 25/81 (31%); Pmedicine use [36/66 (55%) vs. 18/56 (32%); P=0.01] and a lower short inflammatory bowel disease questionnaire score (45.1±2.1 vs. 50.3±1.5; P=0.03). Patients who had used cannabis [60/139 (43%)] were more likely than nonusers [13/133 (10%); Pcannabis for IBD. Cannabis use is common amongst patients with IBD for symptom relief, particularly amongst those with a history of abdominal surgery, chronic abdominal pain and/or a low quality of life index. The therapeutic benefits of cannabinoid derivatives in IBD may warrant further exploration.

    The recently postulated "disease spreading hypothesis" has gained much attention, especially for Parkinson's disease (PD). The various non-motor symptoms (NMS) in neurodegenerative diseases would be much better explained by this hypothesis than by the degeneration of disease-specific cell populations. Motor neuron disease (MND) is primarily known as a group of diseases with a selective loss of motor function. However, recent evidence suggests disease spreading into non-motor brain regions also in MND. The aim of this study was to comprehensively detect NMS in patients suffering from MND. We used a self-rating questionnaire including 30 different items of gastrointestinal, autonomic, neuropsychiatric, and sleep complaints [NMS questionnaire (NMSQuest)], which is an established tool in PD patients. 90 MND patients were included and compared to 96 controls. In total, MND patients reported significantly higher NMS scores (median: 7 points) in comparison to controls (median: 4 points). Dribbling, impaired taste/smelling, impaired swallowing, weight loss, loss of interest, sad/blues, falling, and insomnia were significantly more prevalent in MND patients compared to controls. Interestingly, excessive sweating was more reported in the MND group. Correlation analysis revealed an increase of total NMS score with disease progression. NMS in MND patients seemed to increase with disease progression, which would fit with the recently postulated "disease spreading hypothesis." The total NMS score in the MND group significantly exceeded the score for the control group, but only 8 of the 30 single complaints of the NMSQuest were significantly more often reported by MND patients. Dribbling, impaired swallowing, weight loss, and falling could primarily be connected to motor neuron degeneration and declared as motor symptoms in MND.

    Vitamin D deficiency has been reported in patients with chronic inflammatory conditions, such as rheumatic and inflammatory bowel diseases (IBD). We evaluated the role of biologic therapy on vitamin D, calcium and parathormone (PTH) levels. This cross-sectional study enrolled consecutive patients with either rheumatic diseases or IBD who underwent an ambulatory visit. Patients receiving vitamin D/calcium supplementation were excluded. Vitamin D deficiency or insufficiency was diagnosed when values were rheumatic disease (M/F 37/99; mean age 60.7 ± 12.9 years) and 64 with IBD (M/F 41/23; Mean age 49.6 ± 13.1 years) were enrolled. Vitamin D deficiency/insufficiency was detected in as many as 63.5 % patients, being 61.8 and 67.2 % in patients with either rheumatic diseases or IBD, respectively. The prevalence of vitamin D deficiency/insufficiency was higher in those receiving biologics than other therapies (78.3 vs 43.2 %; p rheumatic diseases (78.7 vs 41 %; p rheumatic diseases or IBD receiving a biologic therapy.

    Full Text Available Gabriel Ortiz1, Len Fromer21Pediatric Pulmonary Services, El Paso, TX; 2Department of Family Medicine, David Geffen School of Medicine, UCLA, Los Angeles, CA, USAAbstract: Chronic obstructive pulmonary disease (COPD is a progressive and debilitating but preventable and treatable disease characterized by cough, phlegm, dyspnea, and fixed or incompletely reversible airway obstruction. Most patients with COPD rely on primary care practices for COPD management. Unfortunately, only about 55% of US outpatients with COPD receive all guideline-recommended care. Proactive and consistent primary care for COPD, as for many other chronic diseases, can reduce hospitalizations. Optimal chronic disease management requires focusing on maintenance rather than merely acute rescue. The Patient-Centered Medical Home (PCMH, which implements the chronic care model, is a promising framework for primary care transformation. This review presents core PCMH concepts and proposes multidisciplinary team-based PCMH care strategies for COPD.Keywords: Patient-Centered Medical Home, chronic care model, chronic obstructive pulmonary disease, patient education, physician assistants, nurse practitioners

    This paper provides a survival analysis of End Stage Renal Disease (ESRD) under Kaplan-Meier Estimates and Weibull Distribution. The data were obtained from the records of V. L. MakabaliMemorial Hospital with respect to time t (patient's age), covariates such as developed secondary disease (Pulmonary Congestion and Cardiovascular Disease), gender, and the event of interest: the death of ESRD patients. Survival and hazard rates were estimated using NCSS for Weibull Distribution and SPSS for Kaplan-Meier Estimates. These lead to the same conclusion that hazard rate increases and survival rate decreases of ESRD patient diagnosed with Pulmonary Congestion, Cardiovascular Disease and both diseases with respect to time. It also shows that female patients have a greater risk of death compared to males. The probability risk was given the equation R = 1 — e-H(t) where e-H(t) is the survival function, H(t) the cumulative hazard function which was created using Cox-Regression.

    Both sleep disorders and pain decrease quality of life in patients with Parkinson's disease (PD). However, little is known about the relationship between objective sleep disturbances and pain in patients with PD. This study aimed to (1) examine the clinical characteristics of pain in PD patients and (2) explore the correlation between pain and sleep disturbances in PD patients. Parkinson's disease patients (N = 144) underwent extensive clinical evaluations of motor and nonmotor symptoms and characteristics of pain. Overnight video-polysomnography was also conducted. Clinical characteristics and sleep parameters were compared between PD patients with or without pain. Pain was reported by 75 patients (52.1%), with 49 (65.3%) reporting pain of at least moderate severity. PD patients with pain were older and had longer disease duration, more severe PD symptoms as assessed by Hoehn and Yahr stage and the Unified Parkinson's Disease Rating Scale, and higher L-dopa equivalent daily dose compared with PD patients without pain. PD patients with pain also showed significantly decreased sleep efficiency (57.06% ± 15.84% vs. 73.80% ± 12.00%, P daily living, depressed mood, higher percentage of N1 sleep, and lower sleep efficiency were independent predictors of pain in patients with PD. Musculoskeletal pain is the most common type of pain in patients with PD. Disrupted sleep continuity, altered sleep architecture, depressed mood, and compromised activities of daily living may be associated with pain in patients with PD. © 2017 World Institute of Pain.

  6. Disease management programs for CKD patients: the potential and pitfalls.

    2009-03-01

    Disease management describes the use of a number of approaches to identify and treat patients with chronic health conditions, especially those that are expensive to treat. Disease management programs have grown rapidly in the United States in the past several years. These programs have been established for patients with chronic kidney disease (CKD), but some have been discontinued because of the high cost of the program. Disease management programs for CKD face unique challenges. Identification of patients with CKD is hampered by incomplete use of the International Classification of Diseases, Ninth Revision (ICD-9) codes for CKD by physicians and the less than universal use of estimated glomerular filtration rate from serum creatinine measurements to identify patients with an estimated glomerular filtration rate less than 60 mL/min/1.73 m(2). CKD affects multiple organ systems. Thus, a comprehensive disease management program will need to manage each of these aspects of CKD. These multiple interventions likely will make a CKD disease management program more costly than similar disease management programs designed for patients with diabetes mellitus, congestive heart failure, or other chronic diseases. The lack of data that can be used to develop effective disease management programs in CKD makes it difficult to determine goals for the management of each organ system affected by CKD. Finally, long periods of observation will be needed to determine whether a particular disease management program is effective in not only improving patient outcomes, but also decreasing both resource use and health care dollars. This long-term observation period is contrary to how most disease management contracts are written, which usually are based on meeting goals during a 1- to 3-year period. Until these challenges are resolved, it likely will be difficult to maintain effective disease management programs for CKD.

    Self-efficacy (SE) is an optimistic self-belief that one can perform a novel task. This concept involves empowerment, self-esteem, and adaptation to a stressful situation. SE is a strong predictor of health behaviors. Our objectives were to study SE in spasmodic dysphonia (SD) and to develop a disease-specific SE-SD scale. Prospective study. Academic hospital. Disease-specific SE-SD items were developed with laryngologists, speech pathologists, and SD patients. These items, General SE Scale, Voice Handicap Index-10 (VHI-10), Consensus Auditory Perceptual Evaluation of Voice (CAPE-V), and Hospital Anxiety and Depression Scale (HADS), were administered to SD patients who presented for botulinum toxin injections. One hundred forty-five SD patients (mean age 59.5 ± 13.6 years) had a general SE score (Cronbach's α = 0.894) of 33.4 ± 5.2 out of 40. This was negatively correlated with HADS-A (r = -0.42, P < 0.001) and HADS-D (r = -0.42, P < .001), but not correlated with VHI-10 (r = -0.098, P = .243) and CAPE-V (r = -0.047, P = .57). Factor analysis selected 8 items from the general SE scale and 5 disease-specific SE-SD items to generate a 13-item disease-specific SE-SD scale (Cronbach's α = 0.907). Disease-specific SE-SD score was 42.1 ± 6.9 out of 52 and was negatively correlated with VHI-10 (r = -0.19, P = .005), HADS-A (r = -0.43, P < .001), and HADS-D (r = -0.57, P < .001), but not correlated with CAPE-V (r = -0.024, P = .60). SD patients established on botulinum toxin injections have high degrees of general and disease-specific SE. Patients with higher SE-SD demonstrate lower vocal handicap and lower levels of anxiety and depression. A 13-item disease-specific SE-SD scale has been developed.

    In string musical instruments, the sound is radiated by the soundboard, subject to the strings excitation. This vibration of this rather complex structure is described here with models which need only a small number of parameters. Predictions of the models are compared with the results of experiments that have been presented in Ege et al. [Vibroacoustics of the piano soundboard: (non)linearity and modal properties in the low- and mid-frequency ranges, Journal of Sound and Vibration 332 (5) (2013) 1288-1305]. The apparent modal density of the soundboard of an upright piano in playing condition, as seen from various points of the structure, exhibits two well-separated regimes, below and above a frequency flim that is determined by the wood characteristics and by the distance between ribs. Above flim, most modes appear to be localised, presumably due to the irregularity of the spacing and height of the ribs. The low-frequency regime is predicted by a model which consists of coupled sub-structures: the two ribbed areas split by the main bridge and, in most cases, one or two so-called cut-off corners. In order to assess the dynamical properties of each of the subplates (considered here as homogeneous plates), we propose a derivation of the (low-frequency) modal density of an orthotropic homogeneous plate which accounts for the boundary conditions on an arbitrary geometry. Above flim, the soundboard, as seen from a given excitation point, is modelled as a set of three structural wave-guides, namely the three inter-rib spacings surrounding the excitation point. Based on these low- and high-frequency models, computations of the point-mobility and of the apparent modal densities seen at several excitation points match published measurements. The dispersion curve of the wave-guide model displays an acoustical radiation scheme which differs significantly from that of a thin homogeneous plate. It appears that piano dimensioning is such that the subsonic regime of acoustical

    In patients with chronic kidney disease the alterations of the endocrine system may arise from several causes. The kidney is the site of degradation as well as synthesis of many different hormones. Moreover, a number of concomitant pathological conditions such as inflammation, metabolic acidosis and malnutrition may participate in the pathogenesis of endocrine abnormalities in this group of patients. The most pronounced endocrine abnormalities in patients with chronic kidney disease are the deficiencies of: calcitriol, testosterone, insulin-like growth factor and, erythropoietin (EPO). Additionally accumulation of several hormones, such as: prolactin, growth hormone and insulin frequently also occur. The clinical consequences of the abovementioned endocrine abnormalities are among others: anemia, infertility and bone diseases.

    To estimate renal disease in recently diagnosed hypertensive patients, and to identify factors related to renal disease. Cross-sectional study, with 425 hypertensive patients recently diagnosed in primary health care; renal disease was estimated with serum creatinine, albumin/creatinine index and glomerular filtration rate (GFR). We analyzed cardiovascular risk factors (CRF), subclinical organ injury and cardiovascular disease following the criteria of the 2007 European Guide of Hypertension. Average age: 58,96 +/- 12,73 years old, 63,3% male. We found dyslipemia in 80%, abdominal obesity in 49% and metabolic syndrome in 36% patients. These patients showed increased serum creatinine 3,3%, a reduction in GFR 9,6%, hidden renal disease 6,4%, microalbuminuria 7,5% and nephropathy 2,4%. Hypertensive patients with renal disease (17,88%) were older, with higher systolic pressure, higher incidence of metabolic syndrome, abnormal carotid intima-media thickness and ankle-arm index, and presence of cardiovascular disease. Variables associated with renal disease were metabolic syndrome (odds ratio = 11,12) and ankle-arm index (odds ratio = 17,55). Variables related to creatinina were sex, ankle-arm index and metabolic syndrome; variables related to GFR were sex, age, ankle-arm index, metabolic syndrome and body mass index (BMI); variables related with albumin/creatinine index included diabetes mellitus. Renal disease is detected in about 2 out of 10 hypertensive patients, when, besides serum creatinina, we analyze albumin/creatinine index and GFR. Metabolic syndrome and ankle-arm index are the main variables associated with renal disease. Copyright 2009 Elsevier España, S.L. All rights reserved.

    Functional imaging of the brain using SPECT provides information correlative to the alterations of regional blood flow. In this paper we review the literature pertaining to SPECT in Parkinson's disease with and without dementia and depression. Parkinson's disease itself is not associated with a consistent pattern of cerebral blood flow alterations in the basal ganglia, but reduced parietal blood flow is more often reported. The heterogeneity of blood flow changes possibly reflects the multifactorial pathophysiology of the disease. In demented Parkinson's disease patients frontal hypoperfusion is often found or bilateral temporoparietal deficits, probably indicative of concomitant Alzheimer's disease. The SPECT studies undertaken in depressed patients with and without Parkinson's disease show highly conflicting and inconsistent results, probably due to methodological and diagnostic flaws (especially the inclusion of demented Parkinson patients). Several lines of reasoning point to a prefrontal dysfunction and future SPECT studies are planned to study this region in non-demented Parkinson's disease patients with and without major depression.

    This study was conducted to characterize the prevalence and clinical features of kleptomania, an impulse control disorder, in patients with Behçet's disease involving the central nervous system. Medical records of 350 patients with neuro-Behçet's disease were evaluated, and clinical and neuropsychological features of patients with kleptomania were noted. Of the 350 neuro-Behçet's disease patients 6 (1.7%) had presented with symptoms that fulfilled the criteria of kleptomania according to the revised 4th version of the Diagnostic and Statistical Manual of Mental Disorders. The 6 patients (5 men, 1 woman) had parenchymal lesions and had developed kleptomania during remission. Magnetic resonance imaging done on the 6 patients before the onset of kleptomania mostly revealed brainstem lesions. Psychiatric assessment did not show any comorbid psychiatric disorders and neuropsychological evaluation showed executive dysfunction in all patients. The 6 patients with kleptomania had developed a frontal lobe syndrome. Copyright © 2013 S. Karger AG, Basel.

    Background Approximately 1.5 million Americans are affected by Parkinson's disease [1] which includes the symptoms of postural instability and gait dysfunction. Currently, clinical evaluations of postural instability and gait dysfunction consist of a subjective rater assessment of gait patterns using items from the Unified Parkinson's Disease Rating Scale, and assessments can be insensitive to the effectiveness of medical interventions. Current research suggests the importance of cycling for Parkinson's disease patients, and while Parkinson's gait has been evaluated in previous studies, little is known about lower extremity control during cycling. The purpose of this study is to examine the lower extremity coordination patterns of Parkinson's patients during cycling. Methods Twenty five participants, ages 44-72, with a clinical diagnosis of idiopathic Parkinson's disease participated in an exercise test on a cycle ergometer that was equipped with pedal force measurements. Crank torque, crank angle and power produced by right and left leg were measured throughout the test to calculate Symmetry Index at three stages of exercise (20 Watt, 60 Watt, maximum performance). Findings Decreases in Symmetry Index were observed for average power output in Parkinson's patients as workload increased. Maximum power Symmetry Index showed a significant difference in symmetry between performance at both the 20 Watt and 60 Watt stage and the maximal resistance stage. Minimum power Symmetry Index did not show significant differences across the stages of the test. While lower extremity asymmetries were present in Parkinson's patients during pedaling, these asymmetries did not correlate to postural instability and gait dysfunction Unified Parkinson's Disease Rating Scale scores. Interpretation This pedaling analysis allows for a more sensitive measure of lower extremity function than the Unified Parkinson's Disease Rating Scale and may help to provide unique insight into current and

Clinical findings were obtained by using the Unified Parkinson’s Disease Rating Scale. Disease severity was measured by the Hoehn and Yahr staging scale, and the Schwab and England Activities of Daily Living scale was used for patient disability. Psychiatric evaluation was performed by the same psychiatrist using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (DSM-IV Axis I Disorders. Severity of depression was measured with the Hamilton Depression Rating Scale. Suicidal ideation and attempts were considered positive if experienced during the patient’s lifetime. The Suicide Probability Scale was used to assess the risk of suicide. Data were analyzed by logistic regression models to identify variables associated with suicidal ideation and attempts.Results: Based on logistic regression analysis, education level, age of disease onset, disease duration, depression, and history of impulse-control disorder (ICD behaviors were significant predictors of suicidal ideation. The risk rate in the presence of depression and history of ICD behaviors was increased by 5.92 and 4.97, respectively. Additionally, lifetime prevalence of suicidal ideation was found in 11.6% (14 of 120 of PD patients, although no patient had ever attempted suicide.Conclusion: Turkish patients with PD who exhibit a high risk for suicidal ideation also experience disease starting at an earlier age, longer disease duration, presence of depression, and ICD behaviors, and should be monitored carefully.Keywords: Parkinson’s disease, suicidal behavior, risk factors

    Previously, we found a significant association between the dopamine D2 receptor gene polymorphism Taq IA and sudden onset of sleep in patients with Parkinson disease. Here we evaluated the association between the preprohypocretin (-909T/C), (-22C/T), and (-20C/A) polymorphisms and sudden onset of sleep in the same population of patients with Parkinson disease. We conducted an association study analyzing the distribution of preprohypocretin polymorphisms in Germanic, caucasian Parkinson disease patients with and without sudden onset of sleep, matched according to drug therapy, disease duration, sex, and age. Movement disorders section at a university hospital. 132 Parkinson disease patients with sudden onset of sleep and 132 Parkinson disease patients without sudden onset of sleep. Blood samples were taken from each participant and used for DNA extraction. Polymorphisms were analyzed by established polymerase chain reaction protocols or direct sequencing. The variant allele T of the (-909T/C) preprohypocretin polymorphism was more commonly found in Parkinson disease patients with sudden onset of sleep. Statistical analysis showed that there were significant differences in the genotype (P = .024) and allele (P = .018) distribution between both groups. For heterozygous and homozygous carriers of allele T, the genotype relative-risk estimates for the presence of sudden onset of sleep were 2.01 (95% confidence interval: 0.76-5.34) and 2.81 (95% confidence interval: 1.09-7.25), respectively. Our results show a significant association between the (-909T/C) preprohypocretin polymorphism and sudden onset of sleep in Parkinson disease. However, we could not demonstrate any interaction between the Taq IA and (-909T/C) polymorphisms with respect to the occurrence of sudden onset of sleep, suggesting that multiple genetic factors may contribute to the pathogenesis of this phenomenon.

    While transradial approach to conduct percutaneous coronary interventions offers multiple advantages, the procedure can cause radial artery damage and occlusion. Because radial artery is the preferred site for the creation of an arteriovenous fistula to provide dialysis, patients with chronic kidney disease are particularly dependent on radial artery for their long-term survival. In this retrospective study, we investigated the prevalence of chronic kidney disease in patients undergoing coronary interventions via radial artery. Stage of chronic kidney disease was based on estimated glomerular filtration rate and National Kidney Foundation - Kidney Disease Outcomes Quality Initiative guidelines. A total of 497 patients undergoing transradial percutaneous coronary interventions were included. Over 70.4% (350/497) of the patients had chronic kidney disease. Stage II chronic kidney disease was observed in 243 (69%) patients (estimated glomerular filtration rate = 76.0 ± 8.4 mL/min). Stage III was observed in 93 (27%) patients (estimated glomerular filtration rate = 49 ± 7.5 mL/min). Stage IV chronic kidney disease was observed in 5 (1%) patients (estimated glomerular filtration rate = 25.6 ± 4.3 mL/min) and Stage V chronic kidney disease was observed in 9 (3%) patients (estimated glomerular filtration rate = 9.3 ± 3.5 mL/min). Overall, 107 of 350 patients (30%) had advanced chronic kidney disease, that is, stage III-V chronic kidney disease. Importantly, 14 of the 107 (13%) patients had either stage IV or V chronic kidney disease. This study finds that nearly one-third of the patients undergoing transradial percutaneous coronary interventions have advanced chronic kidney disease. Because many of these patients may require dialysis, the use of radial artery to conduct percutaneous coronary interventions must be carefully considered in chronic kidney disease population.

    Full Text Available ABSTRACT Periodontal disease has been associated with elevations of blood cytokines involved in atherosclerosis in systemically healthy individuals, but little is known about this association in stable cardiovascular patients. The aim of this study was to assess the association between periodontal disease (exposure and blood cytokine levels (outcomes in a target population of patients with stable coronary artery disease (CAD. Material and Methods This cross-sectional study included 91 patients with stable CAD who had been under optimized cardiovascular care. Blood levels of IL-1β, IL-6, IL-8, IL-10, IFN-γ, and TNF-α were measured by Luminex technology. A full-mouth periodontal examination was conducted to record probing depth (PD and clinical attachment (CA loss. Multiple linear regression models, adjusting for gender, body mass index, oral hypoglycemic drugs, smoking, and occurre:nce of acute myocardial infarction were applied. Results CAD patients that experienced major events had higher concentrations of IFN-γ (median: 5.05 pg/mL vs. 3.01 pg/mL; p=0.01, IL-10 (median: 2.33 pg/mL vs. 1.01 pg/mL; p=0.03, and TNF-α (median: 9.17 pg/mL vs. 7.47 pg/mL; p=0.02. Higher numbers of teeth with at least 6 mm of CA loss (R2=0.07 and PD (R2=0.06 were significantly associated with higher IFN-γ log concentrations. Mean CA loss (R2=0.05 and PD (R2=0.06 were significantly related to IL-10 concentrations. Elevated concentrations of TNF-α were associated with higher mean CA loss (R2=0.07. Conclusion Periodontal disease is associated with increased systemic inflammation in stable cardiovascular patients. These findings provide additional evidence supporting the idea that periodontal disease can be a prognostic factor in cardiovascular patients.

    Patients with celiac disease (CD) are increasingly interconnected through social media, exchanging patient experiences and health-tracking information between individuals through various web-based platforms. Social media represents potentially unique communication interface between gastroenterologists and active social media users - especially young adults and adolescents with celiac disease-regarding adherence to the strict gluten-free diet, gastrointestinal symptoms, and meaningful discussion about disease management. Yet, various social media platforms may be underutilized for research purposes to collect patient-reported outcomes data. In this commentary, we summarize the scientific rationale and potential for future growth of social media in patient-reported outcomes research, focusing on college freshmen with celiac disease as a case study and provide overview of the methodological approach. Finally, we discuss how social media may impact patient care in the future through increasing mobile technology use.

    Increasing prevalence, high morbidity and mortality, and decreased health-related quality of life are hallmarks of peripheral arterial disease. About one-third of peripheral arterial disease patients have intermittent claudication with deleterious effects on everyday activities, such as walking. Exercise training improves peripheral arterial disease symptoms and is recommended as first line therapy for peripheral arterial disease. This review examines the effects of exercise training beyond improvements in walking distance, namely on vascular function, parameters of inflammation, activated hemostasis and oxidative stress, and quality of life. Exercise training not only increases walking distance and physiologic parameters in patients with peripheral arterial disease, but also improves the cardiovascular risk profile by helping patients achieve better control of hypertension, hyperglycemia, obesity and dyslipidemia, thus further reducing cardiovascular risk and the prevalence of coexistent atherosclerotic diseases. American guidelines suggest supervised exercise training, performed for a minimum of 30-45 min, at least three times per week, for at least 12 weeks. Walking is the most studied exercise modality and its efficacy in improving cardiovascular parameters in patients with peripheral arterial disease has been extensively proven. As studies have shown that supervised exercise training improves walking performance, cardiovascular parameters and quality of life in patients with peripheral arterial disease, it should be encouraged and more often prescribed.

    We studied 10 patients with Parkinson's disease and 12 patients with Parkinson-plus-syndrome, trying to improve patients' gait by application of various external rhythmic stimuli, including metronome stimulation (96 beats per minute = middle andante). The test course of the patients was 4 x 10 meters and 3 U-turns. The patients' gait quality under stimulation was compared with their free walk (velocity, number of steps, number of freezing episodes). Metronome stimulation significantly reduced the time and number of steps needed for the test course and also diminished the number of freezing episodes. March music stimulation was less effective and tactile stimulation (rhythmically tapping on the patient's shoulder) even produced negative results. The positive effect of metronome stimulation was also found, when the tests were not performed inside the hospital building, but outside in the hospital parc. Metronome stimulation was comparably effective in both patient sub-groups examined in this study (M. Parkinson, Parkinson-plus-syndrome) and seems to be an important additional help in the treatment of these patients. Electronical metronomes are not expensive, easy in handling, and portable. A theoretical explanation of metronome stimulation effectivity in patients with Parkinson's disease still needs to be elucidated.

    Full Text Available Bone marrow transplantation (BMT is a therapeutic option for patients with genetic storage diseases. Between 1979 and 2002, eight patients, four females and four males (1 to 13 years old were submitted to this procedure in our center. Six patients had mucopolysaccharidosis (MPS I in 3; MPS III in one and MPS VI in 2, one had adrenoleukodystrophy (ALD and one had Gaucher disease. Five patients had related and three unrelated BMT donor. Three patients developed graft versus host disease (two MPS I and one MPS VI and died between 37 and 151 days after transplantation. Five patients survived 4 to 16 years after transplantation. Three patients improved (one MPS I; one MPS VI and the Gaucher disease patient, one patient had no disease progression (ALD and in one patient this procedure did not change the natural course of the disease (MPS III.

    Patients with atopic dermatitis (AD) should be relatively well informed about the disorder to control their condition and prevent flare-ups. Thus far, there is no accurate information about the disease awareness levels and therapeutic behavior of AD patients. To collect data on patients' knowledge about AD and their behavior in relation to seeking information about the disease and its treatment. We performed a questionnaire survey on the disease awareness and self-management behavior of AD patients. A total of 313 patients and parents of patients with AD who had visited the The Catholic University of Korea, Catholic Medical Center between November 2011 and October 2012 were recruited. We compared the percentage of correct answers from all collected questionnaires according to the demographic and disease characteristics of the patients. Although dermatologists were the most frequent disease information sources and treatment providers for the AD patients, a significant proportion of participants obtained information from the Internet, which carries a huge amount of false medical information. A considerable number of participants perceived false online information as genuine, especially concerning complementary and alternative medicine treatments of AD, and the adverse effects of steroids. Some questions on AD knowledge had significantly different answers according to sex, marriage status, educational level, type of residence and living area, disease duration, disease severity, and treatment history with dermatologists. Dermatologists should pay more attention to correcting the common misunderstandings about AD to reduce unnecessary social/economic losses and improve treatment compliance.

    Some patients with hyperthyroid Graves' disease have increased serum T3 and normal or even low serum T4 levels during treatment with antithyroid drugs. These patients with elevated serum T3 to T4 ratios rarely have a remission of their hyperthyroidism. The aim of this study was to investigate thyroid iodine metabolism in such patients, whom we termed T3-predominant Graves' disease. Mean thyroid radioactive iodine uptake was 51.0 +/- 18.1% ( +/- SD) at 3 h, and it decreased to 38.9 +/- 20.1% at 24 h in 31 patients with T3-predominant Graves' disease during treatment. It was 20.0 +/- 11.4% at 3 h and increased to 31.9 +/- 16.0% at 24 h in 17 other patients with hyperthyroid Graves' disease who had normal serum T3 and T4 levels and a normal serum T3 to T4 ratio during treatment (control Graves' disease). The activity of serum TSH receptor antibodies was significantly higher in the patients with T3-predominant Graves' disease than in control Graves' disease patients. From in vitro studies of thyroid tissue obtained at surgery, both thyroglobulin content and iodine content in thyroglobulin were significantly lower in patients with T3-predominant Graves' disease than in the control Graves' disease patients. Thyroid peroxidase (TPO) activity determined by a guaiacol assay was 0.411 +/- 0.212 g.u./mg protein in the T3-predominant Graves' disease patients, significantly higher than that in the control Graves' disease patients. Serum TPO autoantibody levels determined by immunoprecipitation also were greater in T3-predominant Graves' disease patients than in control Graves' disease patients. Binding of this antibody to TPO slightly inhibited the enzyme activity of TPO, but this effect of the antibody was similar in the two groups of patients.

    Finite Element (FE) models of complex structural-acoustic coupled systems can require a large number of degrees of freedom in order to capture their physical behaviour. This is the case in the hearing aid field, where acoustic-mechanical feedback paths are a key factor in the overall system performance and modelling them accurately requires a precise description of the strong interaction between the light-weight parts and the internal and surrounding air over a wide frequency range. Parametric optimization of the FE model can be used to reduce the vibroacoustic feedback in a device during the design phase; however, it requires solving the model iteratively for multiple frequencies at different parameter values, which becomes highly time consuming when the system is large. Parametric Model Order Reduction (pMOR) techniques aim at reducing the computational cost associated with each analysis by projecting the full system into a reduced space. A drawback of most of the existing techniques is that the vector basis of the reduced space is built at an offline phase where the full system must be solved for a large sample of parameter values, which can also become highly time consuming. In this work, we present an adaptive pMOR technique where the construction of the projection basis is embedded in the optimization process and requires fewer full system analyses, while the accuracy of the reduced system is monitored by a cheap error indicator. The performance of the proposed method is evaluated for a 4-parameter optimization of a frequency response for a hearing aid model, evaluated at 300 frequencies, where the objective function evaluations become more than one order of magnitude faster than for the full system.

    Objectives: To prospectively assess dynamic contrast-enhanced (DCE-)MRI as compared to conventional sequences in patients with luminal Crohn's disease. Methods: Patients with Crohn's disease undergoing MRI and ileocolonoscopy within 1 month had DCE-MRI (3T) during intravenous contrast injection of gadobutrol, single shot fast spin echo sequence and 3D T1-weighted spoiled gradient echo sequence, a dynamic coronal 3D T1-weighted fast spoiled gradient were performed before and after gadobutrol. Maximum enhancement (ME) and initial slope of increase (ISI) were calculated for four colon segments (ascending colon + coecum, transverse colon, descending colon + sigmoid, rectum) and (neo)terminal ileum. C-reactive protein (CRP), Crohn's disease activity index (CDAI), per patient and per segment Crohn's disease endoscopic index of severity (CDEIS) and disease duration were determined. Mean values of the (DCE-)MRI parameters in each segment from each patient were compared between four disease activity groups (normal mucosa, non-ulcerative lesions, mild ulcerative and severe ulcerative disease) with Mann–Whitney test with Bonferroni adjustment. Spearman correlation coefficients were calculated for continuous variables. Results: Thirty-three patients were included (mean age 37 years; 23 females, median CDEIS 4.4). ME and ISI correlated weakly with segmental CDEIS (r = 0.485 and r = 0.206) and ME per patient correlated moderately with CDEIS (r = 0.551). ME was significantly higher in segments with mild (0.378) or severe (0.388) ulcerative disease compared to normal mucosa (0.304) (p < 0.001). No ulcerations were identified at conventional sequences. ME correlated with disease duration in diseased segments (r = 0.492), not with CDAI and CRP. Conclusions: DCE-MRI can be used as a method for detecting Crohn's disease ulcerative lesions.

    Abstract BACKGROUND: Patients treated with hemodialysis (HD) have an increased mortality, mainly caused by cardiovascular disease (CVD). Osteoprotegerin (OPG) is a glycoprotein involved in the regulation of the vascular calcification process. Previous studies have demonstrated that OPG.......08; in the adjusted analyses, the p-value for trend was 0.03. CONCLUSIONS: In a high-risk population of hemodialysis patients with previously documented cardiovascular disease, a high level of OPG was an independent risk marker of all-cause mortality....... is a prognostic marker of mortality. The aim of this study was to investigate if OPG was a prognostic marker of all-cause mortality in high-risk patients with end-stage renal disease and CVD. METHODS: We prospectively followed 206 HD patients with CVD. OPG was measured at baseline and the patients were followed...

    Full Text Available Abstract Background Few studies have described patients with foregut dysmotility in inflammatory bowel disease. The aim of this case series was to evaluate clinical characteristics of 5 patients with inflammatory bowel disease and symptoms and signs of upper gut dysmotility. Case presentations We describe a series of four patients with Crohn's disease and one with indeterminate colitis who presented with severe symptoms and signs of gastroparesis. We reviewed medical records of all cases. Gastric emptying of a solid meal was assessed by scintigraphy. Small bowel enteroclysis, gastroduodenoscopy and colonoscopy with biopsies were performed to estimate the activity of the disease and to exclude organic obstruction. None of the patients had any signs of active inflammation or stricture. All of the patients had markedly delayed gastric emptying with a mean t 1/2 of 234 minutes (range 110–380 minutes; normal values 54–94 minutes. Conclusion Clinicians should consider impaired gastric emptying when evaluating patients with Crohn's disease and severe symptoms of upper gut dysmotility, which cannot be attributed to active inflammation or organic obstruction of the digestive tract. Symptoms in these patients are refractory to various therapeutic interventions including tube feeding and gastric surgery.

    Electronic health records (EHRs) are not optimized for chronic disease management. To improve the quality of care for patients with rheumatic disease, we developed electronic data capture, aggregation, display, and documentation software. The software integrated and reassembled information from the patient (via a touchscreen questionnaire), nurse, physician, and EHR into a series of actionable views. Core functions included trends over time, rheumatology-related demographics, and documentation for patient and provider. Quality measures collected included patient-reported outcomes, disease activity, and function. The software was tested and implemented in 3 rheumatology departments, and integrated into routine care delivery. Post-implementation evaluation measured adoption, efficiency, productivity, and patient perception. Over 2 years, 6,725 patients completed 19,786 touchscreen questionnaires. The software was adopted for use by 86% of patients and rheumatologists. Chart review and documentation time trended downward, and productivity increased by 26%. Patient satisfaction, activation, and adherence remained unchanged, although pre-implementation values were high. A strong correlation was seen between use of the software and disease control (weighted Pearson's correlation coefficient 0.5927, P = 0.0095), and a relative increase in patients with low disease activity of 3% per quarter was noted. We describe innovative software that aggregates, stores, and displays information vital to improving the quality of care for patients with chronic rheumatic disease. The software was well-adopted by patients and providers. Post-implementation, significant improvements in quality of care, efficiency of care, and productivity were demonstrated.

    Patients with both anti-glomerular basement membrane (anti-GBM) disease and Castleman disease have been rarely reported. In this study, we report 3 patients with this combination. They had immunologic features similar to patients with classic anti-GBM disease. Sera from the 3 patients recognized the noncollagenous (NC) domain of the α3 chain of type IV collagen (α3(IV)NC1) and its 2 major epitopes, EA and EB. All 4 immunogloblin G (IgG) subclasses against α3(IV)NC1 were detectable, with predominance of IgG1. In one patient with lymph node biopsy specimens available, sporadic plasma cells producing α3(IV)NC1-IgG were found, suggesting a causal relationship between the 2 diseases. One patient, who achieved remission with antibody clearance and normalization of serum creatinine and interleukin 6 concentrations after plasma exchange and 3 cycles of chemotherapy, experienced recurrence of anti-GBM antibodies and an increase in interleukin 6 concentration after chemotherapy discontinuation because of adverse effects, but both returned to normal after another cycle of chemotherapy. This clinical course and the pathologic findings support the hypothesis that the Castleman disease-associated tumor cells are the source of the anti-GBM autoantibodies.

    Full Text Available ABSTRACT BACKGROUND The nutritional status of individuals with inflammatory bowel diseases is directly related to the severity of the disease and is associated with poor prognosis and the deterioration of immune competence. OBJECTIVE To assess the nutritional status and the body composition of outpatients with inflammatory bowel diseases. METHODS A cross-sectional study was conducted with clinical and nutritional assessment of patients with Crohn’s disease and ulcerative colitis. Patients were classified according to the clinical activity through Crohn’s Disease Activity Index and Mayo Score. Nutritional assessment consisted of anthropometric measurements of current weight, height, mid-arm circumference, triceps skinfold thickness and thickness of adductor policis muscle, with subsequent calculation of BMI, arm muscle circumference and the mid-arm muscle area (MAMA. The phase angle (PhA and lean and fat mass were obtained with the use of electrical bioimpedance. Descriptive statistics, chi-square test or Fisher exact test, ANOVA and t-test. RESULTS We evaluated 141 patients of which 54 (38.29% had Crohn’s disease and 87 (61.70% ulcerative colitis. The mean age was 43.98 (±15.68 years in Crohn’s disease and 44.28 (±16.29 years for ulcerative colitis. Most of the patients were in clinical remission of the disease (Crohn’s disease: 88.89%; ulcerative colitis: 87.36%. Regarding the nutritional classification using BMI, it was found that 48.15% of Crohn’s disease patients were eutrophic and 40.74% were overweight or obese; among patients with ulcerative colitis, 52.87% were classified as overweight or obese. When considering the triceps skinfold, it was observed in both groups a high percentage of overweight and obesity (Crohn’s disease: 75.93%; ulcerative colitis: 72.42%. Crohn’s disease patients showed the most affected nutritional status according to the nutritional variables when compared to patients with ulcerative colitis (BMI

    Purpose IgG4-related disease (IgG4-RD) is an immune-mediated fibroinflammatory condition that can affect nearly any organ. No detailed clinical and laboratory assessments have been reported in large numbers of patients with IgG4-RD diagnoses established by strict clinicopathological correlation. Methods We reviewed the baseline features of 125 patients with biopsy-proven disease. The diagnosis was confirmed by pathology review according to consensus diagnostic criteria. Disease activity and damage were assessed by the IgG4-RD Responder Index (RI). Flow cytometry was used to assess levels of circulating plasmablasts. Results Of the 125 patients, 103 had active disease and 86 were on no treatment. Only 51% of the patients with active disease had elevated serum IgG4 concentrations. However, patients with active disease and elevated serum IgG4 concentrations were older, had a higher RI, a greater number of organs involved, lower complement levels, higher absolute eosinophil counts, and higher IgE levels compared to those with active disease but normal serum IgG4 (PIgG4+ plasmablast level and RI (R=0.45, P=0.003) was stronger than that of total plasmablasts and RI. Seventy-six (61%) of the patients were male, but no significant differences according to gender were observed with regard to disease severity, organ involvement, or serum IgG4 concentrations. Glucocorticoids failed to produce sustained remission in the majority of patients. Conclusion Nearly 50% of this patient cohort with biopsy-proven, clinically-active IgG4-RD had normal serum IgG4 concentrations. Serum IgG4 elevation identify a subset with more inflammatory features. IgG4+ plasmablasts correlate well with disease activity. PMID:25988916

    Pancytopenia can rarely complicate Grave's disease. It can be due to uncontrolled thyrotoxicosis or as a result of rare side effect of antithyroid medication. Pernicious anemia leading to Vitamin B12 deficiency is another rare associated cause. We report a case of a patient with Grave's disease and undiagnosed pernicious anemia whom was assumed to have antithyroid drug induced pancytopenia. Failure to recognize this rare association of pernicious anemia as a cause of pancytopenia had resulted in delay in treatment and neurological complication in our patient.

    Celiac disease is an autoimmune enteropathy with variable clinical symptoms. Elderly patients can have different manifestations from those of young patients. The aims of the present study were to investigate whether any differences or similarities exist between older and young patients with celiac disease with a special emphasis on concurrent autoimmune diseases. Celiac disease patients were stratified as older and younger patients. These two groups were then compared by means of clinical symptoms, laboratory parameters and concurrent autoimmune diseases. Factors associated with the presence of an autoimmune disease were identified by univariate and multivariate analysis. There were 66 older patients (mean age 67.7 ± 3.2 years, 50 women), and 277 younger patients (mean age 35.9 ± 11.7 years, 207 women). Of the 66 older patients, eight patients had gastrointestinal symptoms and 58 patients had extradigestive symptoms. In the younger group, the number of patients referred due to gastrointestinal symptoms was higher (8 [12.2%] vs 200 (72.2%), P celiac disease clinically, histologically and by means of laboratory parameters is different in older and young patients. Polyautoimmunity and multiple autoimmune syndrome are more common in older patients compared with younger patients. A biopsy score of Marsh score type, antinuclear antibody positivity, high serum anti-tissue transglutaminase immunoglobulin A level and low hemoglobin level were risk factors for having an autoimmune disease.

    Sexual activity is an important component of patient and partner quality of life for men and women with cardiovascular disease, including many elderly patients. Older adults desire sexual intimacy when there is a partner and a health status that allows sexual relationships. Older individuals desire to love and enjoy sexual activity in relation to personal circumstances, and when health status allows them to experience close relations, most often within marriage especially in our country. Normal changes occur in the phases of sexual cycle with aging, male erectile dysfunction and female sexual dysfunction increase with age. Elderly patients are often affected by multiple organic diseases which can interfere with sexual function especially cardiovascular disease. Treating those disorders or modifying lifestyle-related risk factors may help prevent sexual dysfunction in the elderly. Sexuality is important for older adults and physicians should give their patient's opportunity to voice their concerns with sexual function and offer them alternatives for evaluation and treatment. Asking about sexual health remains difficult or embarrassing for many physicians; in addition, many patients find it difficult to raise sexual issues with their doctor.

    The purpose of our study was to describe the clinical and radiological manifestations of tuberculosis in patients with end-stage renal disease. The medical records, chest radiographs, and CT scans of 42 patients with tuberculosis among 871 consecutive patients with end-stage renal disease were reviewed. Patterns of initial chest radiographs were categorized as primary, postprimary, miliary, or atypical, according to the predominant radiologic findings. Chest radiographs and CT scans revealed pulmonary tuberculosis in 28 patients and extrapulmonary tuberculosis in 15. The pattern of chest radiographs indicative of pulmonary tuberculosis was primary in 12 cases, postprimary in 11, miliary in one, demonstrated atypical infiltrates in three, and was normal in one. Tuberculosis involved the extrathoracic lymph nodes in six cases, the peritoneum in four, the spine in three, and the bone marrow in two. The primary pattern, seen in 12 patients, manifested as pleural effusion or segmental consolidation, and in ten of the twelve the former was dominant. The radiological pattern of pulmonary tuberculosis in end-stage renal disease is often primary, and extrapulmonary involvement is frequent

    Sickle cell disease is a chronic hematologic disease with a variety of acute, and often recurring, complications. Vaso-occlusive crisis, a unique but common presentation in sickle cell disease, can be challenging to manage. Acute chest syndrome is the leading cause of death in patients with sickle cell disease, occurring in more than half of patients who are hospitalized with a vaso-occlusive crisis. Uncommon diagnoses in children, such as stroke, priapism, and transient red cell aplasia, occur more frequently in patients with sickle cell disease and necessitate a degree of familiarity with the disease process and its management. Patients with sickle cell trait generally have a benign course, but are also subject to serious complications. This issue provides a current review of evidence-based management of the most common acute complications of sickle cell disease seen in pediatric patients in the emergency department.

    - Previous evidence trying to assess the risk of celiac disease among dyspeptic patients has been inconclusive, showing in some cases notorious discrepancies. - To determine the prevalence of celiac disease in patients with dyspepsia compared to healthy controls without dyspepsia. - Adult patients under evaluation for dyspepsia were invited to participate. These patients were offered an upper gastrointestinal endoscopy with duodenal biopsies. On the other hand, asymptomatic adult volunteers who performed a preventive visit to their primary care physician were invited to participate and agreed to undertake an upper gastrointestinal endoscopy with duodenal biopsies as well. Those patients with histologic signs of villous atrophy were furtherly evaluated and serological tests were performed in order to determine celiac disease diagnosis. Celiac disease prevalence was compared between groups. - Overall, 320 patients with dyspepsia and 320 healthy controls were recruited. There were no significant differences in terms of gender or age between groups. Celiac disease diagnosis was made in 1.25% (4/320) of patients in the dyspepsia group versus 0.62% (2/320) in the control group. - Patients with dyspepsia who underwent routine duodenal biopsies did not show an increased risk for celiac disease when compared to healthy individuals.

    Full Text Available Abstract Objective Few studies have been published on health care utilization in Crohn's disease and the influence of psychological treatment on high utilizers. Methods The present sub study of a prospective multi center investigation conducted in 87 of 488 consecutive Crohn's disease (CD patients was designed to investigate the influence of the course of Crohn's disease on health care utilization (hospital days (HD and sick leave days (SLD collected by German insurance companies and to examine the conditions of high-utilizing patients. Predictors of health care utilization should be selected. Based on a standardized somatic treatment, high health care utilizing patients of the psychotherapy and control groups should be compared before and after a one-year treatment. Results Multivariate regression analysis identified disease activity at randomization as an important predictor of the clinical course (r2 = 0.28, p 2 = 0.15, p = 0.09. The patients' level of anxiety, depression and lack of control at randomization predicted their health-related quality of life at the end of the study (r2 = 0.51, p 2 = 0.22, p Among high utilizers, a significantly greater drop in HD (p Conclusion The course of Crohn's disease is influenced by psychological as well as somatic factors; especially depression seems important here. A significant drop of health care utilization demonstrates the benefit of psychological treatment in the subgroup of high-utilizing CD patients. Further studies are needed to replicate the findings of the clinical outcome in this CD subgroup.

    The aim of this study was to assess our clinical experience with infliximab, a monoclonal antitumor necrosis factor antibody, following its approval for treatment of refractory Crohn's disease (CD). We followed 100 consecutive patients with CD (53 women and 47 men; mean age, 41 yr) who received a total of 233 infliximab (5 mg/kg) infusions. Adverse events were noted and clinical response assessed every 2 wk for 6 months after each infusion using the Harvey Bradshaw Index (HBI) for active disease, the Perianal Disease Activity Index (PDAI) for fistulous disease, and steroid withdrawal rates for steroid-sparing efficacy. Indications for therapy were active disease (n = 57), perianal fistulous disease (n = 33), and steroid dependency (n = 10). Significant infusion reactions occurred in 16 patients (6.9% of infusions) including anaphylactic shock in one patient. Fourteen patients experienced infectious adverse events, 13 of whom were on concurrent steroids. Sixty percent of patients with active disease experienced > or = 50% HBI reduction at 2 wk; mean duration of response, 8.2 wk. Three of 26 first-time nonresponders with active disease (12%) responded to a second infusion. Sixty-nine percent of patients with fistulous disease experienced >50% reduction in their PDAI at 2 wk; mean duration of response, 10.9 wk. Four of 10 steroid-dependent patients (40%) discontinued steroid therapy, one of whom recommenced steroid therapy at 24 wk. Our clinical response rates mirror the efficacy reported in the controlled trials for active and fistulous disease. Steroid-sparing efficacy was seen in 40% of steroid-dependent patients. Concurrent steroids did not reduce the risk of significant infusion reactions (6.9%), but did increase the risk of infections.

    Web-based patient education materials and printed pamphlets are frequently used by providers to inform patients about their rheumatic disease. Little attention has been given to the readability and appropriateness of patient materials. The objective of this study was to examine the readability and suitability of commonly used patient education materials for osteoarthritis (OA), rheumatoid arthritis, systemic lupus erythematosus, and vasculitis. Five or 6 popular patient resources for each disease were chosen for evaluation. Readability was measured using the Flesch-Kincaid reading grade level and suitability was determined by the Suitability Assessment of Materials (SAM), a score that considers characteristics such as content, graphics, layout/topography, and cultural appropriateness. Three different reviewers rated the SAM score and means were used in the analysis. Twenty-three resources written on the 4 diseases were evaluated. The education material for all 4 diseases studied had readability above the eighth-grade level and readability did not differ among the diseases. Only 5 of the 23 resources received superior suitability scores, and 3 of these 5 resources were written for OA. All 4 diseases received adequate suitability scores, with OA having the highest mean suitability score. Most patient education materials for rheumatic diseases are written at readability levels above the recommended sixth-grade reading level and have only adequate suitability. Developing more appropriate educational resources for patients with rheumatic diseases may improve patient comprehension. Copyright © 2013 by the American College of Rheumatology.

    Cushing's disease which is a consequence of ACTH-secreting pituitary adenoma leads to hypercortisolism. Cushing's disease is associated with several psychiatric disturbances. The aim of the present study was to identify which psychiatric disorders were present in patients with Cushing's disease over a 2-year period and to monitor their general psychiatric condition. Additionally, the study aimed to examine the relationship between the duration of Cushing's disease, and the severity of psychiatric conditions based on psychiatric rating scales. The study included 39 patients with Cushing's disease that underwent neurosurgery for ACTH-secreting pituitary adenomas. The transsphenoidal approach (the standard microsurgery technique) was performed in all patients. ACTH-secreting pituitary adenomas were confirmed based on immunohistochemistry in all patients. Psychiatric conditions in the patients were identified using the Clinical Global Impression Scale (CGI) and ICD 10 diagnostic criteria at 3 time points: prior to surgery, and 6 and 48 months post surgery. The Cushing's disease patients exhibited statistically significant improvement in their psychiatric condition, according to the CGI, 6 and 48 months post surgery. There wasn't any significant correlation between the duration of Cushing's disease and psychiatric status, as measured by the CGI prior to surgery, 6 months post surgery, or 48 months post surgery. Patients with Cushing's disease had a significant level psychiatric disturbance that remitted after surgery. There wasn't a significant correlation between the duration of Cushing's disease and psychiatric status.

    Bisphenol A (BPA) is a widely distributed estrogen-mimetic molecule, with well-established effects on the dopaminergic system. It can be found in canned food, dental sealants, thermal paper, etc. BPA undergoes liver conjugation with glucuronic acid and is subsequently excreted in the urine. In the present study we quantified the concentration of free and conjugated Bisphenol A in blood of patients affected by Parkinson Disease, using their spouses as controls. An interview was performed to determine possible confounders in BPA exposure. Free and conjugated BPA were quantified by gas chromatography coupled with mass spectrometry. Parkinson's Disease patients carried a statistically significant lower amount of conjugated Bisphenol A compared to controls. The two populations were mostly homogeneous in terms of exposure to possible Bisphenol A sources. The only exceptions were exposure to canned tuna and canned tomatoes PD patients consumed significantly more of both (pBisphenol A glucuronidation was found after stratification by typology of anti-Parkinson's drug taken and after conversion to the Levodopa Equivalent Daily Dose. BPA glucuronidation was decreased in patients with Parkinson disease. The possible unique mechanisms underlying Bisphenol A metabolism in PD patients deserve further elucidation. Moreover, further study is needed to assess a possible BPA role in Parkinson's Disease pathogenesis, due to its documented dopaminergic toxicity. Copyright © 2017 Elsevier B.V. All rights reserved.

    Although Alzheimer’s disease (AD) primarily manifests as cognitive deficits, the implicit sensorimotor processes that underlie social interactions, such as automatic imitation, seem to be preserved in mild and moderate stages of the disease, as is the ability to communicate with other persons. Nevertheless, when AD patients face more challenging tasks, which do not rely on automatic processes but on explicit voluntary mechanisms and require the patient to pay attention to external events, the cognitive deficits resulting from the disease might negatively affect patients’ behavior. The aim of the present study was to investigate whether voluntary motor imitation, i.e., a volitional mechanism that involves observing another person’s action and translating this perception into one’s own action, was affected in patients with AD. Further, we tested whether this ability was modulated by the nature of the observed stimulus by comparing the ability to reproduce the kinematic features of a human demonstrator with that of a computerized-stimulus. AD patients showed an intact ability to reproduce the velocity of the observed movements, particularly when the stimulus was a human agent. This result suggests that high-level cognitive processes involved in voluntary imitation might be preserved in mild and moderate stages of AD and that voluntary imitation abilities might benefit from the implicit interpersonal communication established between the patient and the human demonstrator.

    The prevalence of coeliac disease among patients with autoimmune hypothyroidism has not been studied before in Jordan and other Arab countries. A cross-sectional record-based review was made of all adult autoimmune hypothyroidism patients who attended a referral centre in Jordan, during an 8-month period. Coeliac disease in these patients was diagnosed by the attending physician based on positive serological tests for anti-endomysial antibodies IgA and IgG followed by duodenal biopsy to confirm the diagnosis of coeliac disease. Of 914 patients recruited, 117 (12.8%) were seropositive for coeliac disease. Of 87 seropositive patients who underwent duodenal biopsy, 39 had positive histological findings of coeliac disease (44.8%). Extrapolating from these findings the overall rate of coeliac disease among autoimmune hypothyroidism patients was estimated to be 5.7%. In multivariate logistic regression coeliac disease was significantly associated with older age (> 40 years), presence of other autoimmune diseases, vitamin B12 deficiency and anaemia.

    Chronic liver disease presents a relative contraindication to warfarin therapy, but some patients with liver disease nevertheless require long-term anticoagulation. The goal is to identify which patients with liver disease might safely receive warfarin. Among 102 134 patients who received warfarin from the Veterans Affairs from 2007 to 2008, International Classification of Diseases-Ninth Revision codes identified 1763 patients with chronic liver disease. Specific diagnoses and laboratory values (albumin, aspartate aminotransferase, alanine aminotransferase, creatinine, and cholesterol) were examined to identify risk of adverse outcomes, while controlling for available bleeding risk factors. Outcomes included percent time in therapeutic range, a measure of anticoagulation control, and major hemorrhagic events, by International Classification of Diseases-Ninth Revision codes. Patients with liver disease had lower mean time in therapeutic range (53.5%) when compared with patients without (61.7%; P<0.001) and more hemorrhages (hazard ratio, 2.02; P<0.001). Among patients with liver disease, serum albumin and creatinine levels were the strongest predictors of both outcomes. We created a 4-point score system: patients received 1 point each for albumin (2.5-3.49 g/dL) or creatinine (1.01-1.99 mg/dL), and 2 points each for albumin (<2.5 g/dL) or creatinine (≥2 mg/dL). This score predicted both anticoagulation control and hemorrhage. When compared with patients without liver disease, those with a score of zero had modestly lower time in therapeutic range (56.7%) and no increase in hemorrhages (hazard ratio, 1.16; P=0.59), whereas those with the worst score (4) had poor control (29.4%) and high hazard of hemorrhage (hazard ratio, 8.53; P<0.001). Patients with liver disease receiving warfarin have poorer anticoagulation control and more hemorrhages. A simple 4-point scoring system using albumin and creatinine identifies those at risk for poor outcomes. © 2014 American

    To evaluate the extent of complementary and alternative medicine use and perceived effectiveness in patients with lysosomal storage diseases. A 26-item survey was distributed to 495 patients with type 1 Gaucher, Fabry, and type B Niemann-Pick diseases who were seen at the Lysosomal Storage Disease Program at the Mount Sinai School of Medicine. Survey responses were entered into an access database and analyzed using descriptive statistics. Surveys were completed by 167 respondents with an overall response rate of 34%. Complementary and alternative medicines were used by 45% of patients with type 1 Gaucher disease, 41% of patients with Fabry disease, and 47% of patients with type B Niemann-Pick for symptoms related to their disease. Complementary and alternative medicines were used most frequently by adult females (55%), in patients who reported having one or more invasive procedures due to their disease, patients who use one or more conventional medical therapies, or those with depression and/or anxiety. Overall perceived effectiveness of complementary and alternative medicine supplements was low; however, complementary and alternative medicine therapies were perceived as effective. Complementary and alternative medicines are commonly used among patients with lysosomal storage diseases. Assessment of the effectiveness of these approaches in the lysosomal storage diseases is needed, and physicians should be aware of complementary and alternative medicine therapies used by patients to evaluate safety and possible drug interactions.

    A few decades ago, patients with Chagas disease were predominantly rural workers, with a low risk profile for obstructive coronary artery disease (CAD). As urbanization has increased, they became exposed to the same risk factors for CAD of uninfected individuals. Dobutamine stress echocardiography (DSE) has proven to be an important tool in CAD diagnosis. Despite being a potentially arrhythmogenic method, it is safe for coronary patients without Chagas disease. For Chagas disease patients, however, the indication of DSE in clinical practice is uncertain, because of the arrhythmogenic potential of that heart disease. To assess DSE safety in Chagas disease patients with clinical suspicion of CAD, as well as the incidence of arrhythmias and adverse events during the exam. Retrospective analysis of a database of patients referred for DSE from May/2012 to February/2015. This study assessed 205 consecutive patients with Chagas disease suspected of having CAD. All of them had their serology for Chagas disease confirmed. Their mean age was 64±10 years and most patients were females (65.4%). No patient had significant adverse events, such as acute myocardial infarction, ventricular fibrillation, asystole, stroke, cardiac rupture and death. Regarding arrhythmias, ventricular extrasystoles occurred in 48% of patients, and non-sustained ventricular tachycardia in 7.3%. DSE proved to be safe in this population of Chagas disease patients, in which no potentially life-threatening outcome was found. Até poucas décadas atrás, os pacientes chagásicos eram predominantemente trabalhadores rurais, com baixo perfil de risco para doença obstrutiva coronária. Com a crescente urbanização, passaram a ter os mesmos fatores de risco para doença aterosclerótica que indivíduos não infectados. O ecocardiograma sob estresse com dobutamina (EED) é uma importante ferramenta no diagnóstico de coronariopatia. É referido, porém, como um método potencialmente arritmogênico, mas

    The National Aeronautics and Space Administration (NASA) Constellation Program (CxP) has identified a series of tests to provide insight into the design and development of the Crew Launch Vehicle (CLV) and Crew Exploration Vehicle (CEV). Ares I-X was selected as the first suborbital development flight test to help meet CxP objectives. The Ares I-X flight test vehicle (FTV) is an early operational model of CLV, with specific emphasis on CLV and ground operation characteristics necessary to meet Ares I-X flight test objectives. The in-flight part of the test includes a trajectory to simulate maximum dynamic pressure during flight and perform a stage separation of the Upper Stage Simulator (USS) from the First Stage (FS). The in-flight test also includes recovery of the FS. The random vibration response from the ARES 1-X flight will be reconstructed for a few specific locations that were instrumented with accelerometers. This recorded data will be helpful in validating and refining vibration prediction tools and methodology. Measured vibroacoustic environments associated with lift off and ascent phases of the Ares I-X mission will be compared with pre-flight vibration predictions. The measured flight data was given as time histories which will be converted into power spectral density plots for comparison with the maximum predicted environments. The maximum predicted environments are documented in the Vibroacoustics and Shock Environment Data Book, AI1-SYS-ACOv4.10 Vibration predictions made using statistical energy analysis (SEA) VAOne computer program will also be incorporated in the comparisons. Ascent and lift off measured acoustics will also be compared to predictions to assess whether any discrepancies between the predicted vibration levels and measured vibration levels are attributable to inaccurate acoustic predictions. These comparisons will also be helpful in assessing whether adjustments to prediction methodologies are needed to improve agreement between the

    Hepatocellular carcinoma rarely occurs in patients without underlying cirrhosis or liver disease. While inflammatory bowel disease has been linked to certain forms of liver disease, hepatocellular carcinoma is exceedingly rare in these patients. We report the twelfth case of hepatocellular carcinoma in a patient with Crohn's disease. The patient is a 61-year-old with longstanding Crohn's disease who was treated with azathioprine and was found to have elevated liver enzymes and a new 3-cm liver mass on ultrasound. A complete workup for underlying liver disease was unremarkable and liver biopsy revealed hepatocellular carcinoma. The patient underwent a hepatic resection, and there is no evidence of recurrence at the 11-month follow-up. The resection specimen showed no evidence of cancer despite the initial biopsy revealing hepatocellular carcinoma. This case represents the third biopsy-proven complete spontaneous regression of hepatocellular carcinoma. Although large studies have failed to show a definite link between azathioprine and hepatocellular carcinoma, the relationship remains concerning given the multiple case reports suggesting a possible association. Clinicians should exercise a high degree of suspicion in patients with Crohn's disease who present with elevated liver enzymes, especially those on azathioprine therapy. PMID:27403102

    The purpose of this study was to assess the relation between the extent of coronary artery disease (CAD) and size of exercise-induced myocardial hypoperfusion in 79 patients with angiographically documented CAD. None of the patients had Q-wave myocardial infarction. Fifty patients had one-vessel disease, ten had two-vessel disease, and 19 patients had three-vessel or left main disease. From a scintigraphic functional standpoint, patients were classified into two groups: 28 patients (35%) had large perfusion defects and 51 patients (65%) had small defects. The size of the thallium-201 perfusion defect during exercise was assessed as the perimeter of the defect in each projection expressed as a percentage abnormality of the total left ventricular perimeter in that projection. The average abnormality from the three projections was used in the final analysis. Eleven patients with large defects (39%) had one-vessel disease and 12 patients with small defects (24%) had multivessel disease. Stepwise multivariate discriminate analysis identified the number of diseased vessels (F . 13.9), the change in systolic blood pressure from rest to exercise (F . 10.8), the exercise heart rate (F . 9.1), and exercise electrocardiographic response (F . 7.8) as significant associates of the size of the perfusion defect (predictive accuracy . 70%). We conclude that the size of hypoperfused myocardium during exercise is variable in patients with CAD. Discriminate analysis identified the extent of CAD, exercise heart rate, change in systolic pressure from rest to exercise, and exercise electrocardiographic response as significant associates of the size of the defect

  6. Should the patient with coronary artery disease use sildenafil?

    Since the etiology of erectile dysfunction is frequently related to endothelial dysfunction, a problem in common with much vascular disease, erectile dysfunction disproportionately affects patients with cardiovascular disease. With the development of phosphodiesterase 5 inhibitors, the first of which was sildenafil (Viagra), an effective oral medication became available. The question of safety of these drugs, especially in patients with latent or overt coronary artery disease, is of concern. Sildenafil relaxes smooth muscle and therefore lowers systolic and diastolic blood pressure slightly. With organic nitrates, the drop in blood pressure is potentiated, at times dangerously, thereby making it contraindicated to take nitrates within 24 hours of using sildenafil. In double-blind, placebo-controlled trials, there was no difference between sildenafil subjects and control patients in the incidence of myocardial infarction, cardiovascular, and total deaths. Coronary disease patients with stable angina, controlled on medications, were included in the trials. Therefore, sildenafil, as a drug, is safe in such patients. With a patient with coronary artery disease suddenly engaging in the physical exercise associated with sexual intercourse, there is the danger of increased risk of precipitating myocardial infarction or death. The cardiovascular metabolic cost of sexual activity is reviewed and appears to be approximately at the level of 3-5 metabolic equivalents of exercise. Sexual activity occurs within 2 hours of the onset of an acute myocardial infarction in life will be markedly improved by their ability to engage in sexual activity.

  7. Clinical Utility of Serologic Testing for Celiac Disease in Asymptomatic Patients

    Science.gov (United States)

    2011-01-01

    Executive Summary Objective The objective of this evidence-based analysis was to evaluate the clinical utility of serologic testing for celiac disease in asymptomatic individuals presenting with one of the non-gastrointestinal conditions evaluated in this report. The clinical utility was based on the effects of a gluten-free diet (GFD) on outcomes specific to each of these conditions. The prevalence of celiac disease in asymptomatic individuals and one of these non-gastrointestinal conditions was also evaluated. Clinical Need and Target Population Celiac Disease Celiac disease is an autoimmune disease characterized by a chronic inflammatory state of the proximal small bowel mucosa accompanied by structural and functional changes. Technology Under Evaluation Serologic Tests for Celiac Disease There are a number of serologic tests for celiac disease available. Serologic tests are automated with the exception of the anti-endomysial antibody test, which is more time-consuming and operator-dependent than the other tests. Research Questions What is the prevalence of asymptomatic celiac disease in patients presenting with one of the non-gastrointestinal conditions evaluated? What is the effect of the gluten-free diet on condition-specific outcomes in patients with asymptomatic celiac disease presenting with one of the non-gastrointestinal conditions evaluated? What is the clinical utility of serologic testing for celiac disease in asymptomatic patients presenting with one of the non-gastrointestinal conditions evaluated? The clinical utility was defined as the impact of the GFD on disease specific outcomes. What is the risk of all-cause mortality and lymphoma in individuals with asymptomatic celiac disease? What is the budget impact of serologic testing for celiac disease in asymptomatic subjects presenting with one of the non-gastrointestinal conditions evaluated? Research Methods Study Population The study population consisted of individuals with newly diagnosed celiac

    BACKGROUND: Several case reports, but only a few studies, have examined the coexistence of coeliac disease and primary biliary cirrhosis. AIM: To estimate the risk of primary biliary cirrhosis in two national cohorts of patients with coeliac disease in Denmark and Sweden. METHODS: Through record...... linkage all Danish patients hospitalised with coeliac disease were followed for possible occurrence of primary biliary cirrhosis from 1 January 1977 until 31 December 1992. All patients hospitalised with coeliac disease in Sweden from 1987 to 1996 were also followed in a separate analysis. RESULTS......: A total of 896 patients with coeliac disease were identified in Denmark with a median follow up period of 9.1 years for a total of 8040 person-years at risk. Two cases of primary biliary cirrhosis were observed where 0.07 were expected, giving a standardised incidence ratio of 27.6 (95% confidence...

    Acute Lyme disease results from transmission of and infection by the bacterium Borrelia burgdorferi following a tick bite. During acute infection, bacteria can disseminate to the central nervous system (CNS) leading to the development of Lyme meningitis. Here we have analyzed pooled cerebrospinal fluid (CSF) allowing for a deep view into the proteome for a cohort of patients with early-disseminated Lyme disease and CSF inflammation leading to the identification of proteins that reflect host responses, which are distinct for subjects with acute Lyme disease. Additionally, we analyzed individual patient samples and quantified changes in protein abundance employing label-free quantitative mass spectrometry based methods. The measured changes in protein abundances reflect the impact of acute Lyme disease on the CNS as presented in CSF. We have identified 89 proteins that differ significantly in abundance in patients with acute Lyme disease. A number of the differentially abundant proteins have been found to be localized to brain synapse and thus constitute important leads for better understanding of the neurological consequence of disseminated Lyme disease.

    Adaptation to a chronic somatic disease depends on a variety of factors, including belief in health locus of control. Correlation between health locus of control and illness acceptance in patients with Graves-Basedow and Hashimoto diseases as well as correlation between health locus of control, illness acceptance, sex, and age. THREE METHODS WERE APPLIED: Multidimensional Health Locus of Control Scale by K.A. Wallston, B.S. Wallston and R. DeVellis; the Acceptance of Illness Scale by B.J. Felton, T.A. Revenson, and G.A. Hinrichsena; and a personal questionnaire. Two groups were subject to the research: 68 patients with Graves-Basedow disease and 54 patients with Hashimoto disease. Patients with Graves-Basedow disease, women above all, have their health locus of control in other persons (P = 0,001) and are less inclined to accept their illness (P = 0,005) when compared to patients with Hashimoto disease. A statistically significant correlation occurred between the age of patients and external (i.e., in other persons) health locus of control. Beliefs in health locus of control and type of illness in female patient group are predictors of illness acceptance (P = 0,0009).

    Full Text Available BACKGROUND: Celiac disease is a small intestinal inflammatory disorder characterized by malabsorption, nutrient deficiency, and a range of clinical manifestations. It is caused by an inappropriate immune response to dietary gluten and is treated with a gluten-free diet. Recent feeding studies have indicated oats to be safe for celiac disease patients, and oats are now often included in the celiac disease diet. This study aimed to investigate whether oat intolerance exists in celiac disease and to characterize the cells and processes underlying this intolerance. METHODS AND FINDINGS: We selected for study nine adults with celiac disease who had a history of oats exposure. Four of the patients had clinical symptoms on an oats-containing diet, and three of these four patients had intestinal inflammation typical of celiac disease at the time of oats exposure. We established oats-avenin-specific and -reactive intestinal T-cell lines from these three patients, as well as from two other patients who appeared to tolerate oats. The avenin-reactive T-cell lines recognized avenin peptides in the context of HLA-DQ2. These peptides have sequences rich in proline and glutamine residues closely resembling wheat gluten epitopes. Deamidation (glutamine-->glutamic acid conversion by tissue transglutaminase was involved in the avenin epitope formation. CONCLUSIONS: We conclude that some celiac disease patients have avenin-reactive mucosal T-cells that can cause mucosal inflammation. Oat intolerance may be a reason for villous atrophy and inflammation in patients with celiac disease who are eating oats but otherwise are adhering to a strict gluten-free diet. Clinical follow-up of celiac disease patients eating oats is advisable.

    Chronic kidney disease (CKD) and end-stage renal disease (ESRD) have emerged as a worldwide public health problem. Due to the remarkably higher incidence and prevalence of this chronic disease in Taiwan than in other countries, CKD/ESRD has contributed to a significant health burden in Taiwan. Patients with CKD/ESRD have an increased risk of coronary artery disease (CAD) and acute coronary syndrome (ACS) compared to the normal population. Patients with ACS alone can present differently than patients with ACS and CKD/ESRD. Also, due to the lower prevalence of chest pain and ST-segment elevation, CKD/ESRD patients were more difficult to diagnose than other patients. Furthermore, whether advances in ACS management with medical therapy and an early invasive approach could improve patient outcomes with CKD/ESRD is not known. The use of antiplatelets such as aspirin and other antithrombotic agents might reduce the incidence of ACS or stroke in CKD patients. However, such use could also increase bleeding risk and even increase the likelihood of mortality, especially in dialysis patients. While recent clinical data suggest the potential benefit of aggressive management with coronary intervention for CAD and ACS in this category of patients, further clinical studies are still indicated for the proper medical strategy and revascularization therapy to improve the outcomes of CAD and ACS in CKD/ESRD patients, both in Taiwan and worldwide.

    Full Text Available ABSTRACT BACKGROUND Previous evidence trying to assess the risk of celiac disease among dyspeptic patients has been inconclusive, showing in some cases notorious discrepancies. OBJECTIVE To determine the prevalence of celiac disease in patients with dyspepsia compared to healthy controls without dyspepsia. METHODS Adult patients under evaluation for dyspepsia were invited to participate. These patients were offered an upper gastrointestinal endoscopy with duodenal biopsies. On the other hand, asymptomatic adult volunteers who performed a preventive visit to their primary care physician were invited to participate and agreed to undertake an upper gastrointestinal endoscopy with duodenal biopsies as well. Those patients with histologic signs of villous atrophy were furtherly evaluated and serological tests were performed in order to determine celiac disease diagnosis. Celiac disease prevalence was compared between groups. RESULTS Overall, 320 patients with dyspepsia and 320 healthy controls were recruited. There were no significant differences in terms of gender or age between groups. Celiac disease diagnosis was made in 1.25% (4/320 of patients in the dyspepsia group versus 0.62% (2/320 in the control group. CONCLUSION Patients with dyspepsia who underwent routine duodenal biopsies did not show an increased risk for celiac disease when compared to healthy individuals.

    The mechanism of fever in patients with Hodgkin's disease was investigated by examining endogenous pyrogen production by blood, spleen, and lymph node cells incubated in vitro. Blood leucocytes from febrile or afebrile patients with Hodgkin's disease did not produce pyrogen spontaneously. Spleen cells, however, frequently released pyrogen during initial incubations, unlike spleen cells from patients with non-malignant diseases. Pyrogen production occurred from spleens without observed pathologic infiltrates of Hodgkin's disease. Lymph nodes involved with Hodgkin's disease produced pyrogen more frequently than did nodes involved with other diseases. Pyrogen production by tissue cells was prolonged, required protein synthesis, and in some cases was due to mononuclear cells; it did not correlate with fever in the patient. These studies demonstrate spontaneous production of endogenous pyrogen in vitro by lymphoid tissue cells from patients with Hodgkin's disease.

    Castleman disease is a rare lymphoproliferative disorder. Surgery is considered standard therapy for the unicentric type. However, case reports have documented favorable responses to radiotherapy. The aim of this study was to analyse the clinical outcomes of five patients with unicentric Castleman disease treated with radiotherapy between 1991 and 2005. Mediastinal lymph nodes were the most common site of disease (four patients). Three patients were treated with radiotherapy alone, two patients with surgery and radiotherapy. Patients were treated with radiotherapy doses ranging from 40 Gy to 50 Gy. The median follow-up was 12 months (range, 3-175 months). During follow-up only one patient had progressive disease and died of Castleman disease. At the time of last follow-up two patients were in complete remission, one patient in partial remission, and one patient had stable disease. One patient showed serious acute and late toxicities. At the end of radiotherapy a paraneoplastic pemphigus vulgaris occurred, and eight to 11 months after radiotherapy a stenosis of the esophagus, of the left bronchus, and of the trachea due to scars. The study shows that unicentric Castleman disease is successfully treated with radiotherapy. However, for detection of possible complications as pemphigus vulgaris or stenosis of the esophagus or trachea an accurate follow-up is necessary

    Advanced pulmonary disorders are linked to esophageal hypomotility and reflux disease. However, characterization of esophageal function using high resolution manometry (HRM) and ambulatory pH monitoring, segregation by pulmonary pathology, and comparison to traditional reflux disease are all limited in the literature. Over a 4 year period, 73 patients (55.2 ± 1.3 years, 44F) were identified who underwent esophageal function testing as part of lung transplant evaluation for advanced pulmonary disease (interstitial lung disease, ILD = 47, obstructive lung disease, OLD = 24, other = 2). Proportions of patients with motor dysfunction (≥ 80% failed sequences = severe hypomotility) and/or abnormal reflux parameters (acid exposure time, AET ≥ 4%) were determined, and compared to a cohort of 1081 patients (48.4 ± 0.4 years, 613F) referred for esophageal function testing prior to antireflux surgery (ARS). The proportion of esophageal body hypomotility was significantly higher within advanced pulmonary disease categories (35.6%), particularly ILD (44.7%), compared to ARS patients (12.1%, P esophageal motor pattern or reflux evidence. Interstitial lung disease has a highly significant association with esophageal body hypomotility. Consequently, prevalence of abnormal esophageal acid exposure is high, but implications for post lung transplant chronic rejection remain unclear. © 2013 John Wiley & Sons Ltd.

    Few large-scale studies have quantified the burden of comorbid autoimmune diseases in patients with vitiligo. We sought to determine the prevalence of comorbid autoimmune diseases in patients with vitiligo. We conducted a manual chart review on a cohort of 1873 patients with vitiligo seen between January 2002 and October 2012 at the Henry Ford Health System in Detroit, MI. Patients were excluded if they had fewer than 2 dermatology notes (N = 595) or if they were never given a diagnosis of vitiligo by a dermatologist (N = 180). Of 1098 patients with vitiligo, nearly 20% had at least 1 comorbid autoimmune disease. Compared with the general US population, we found a higher prevalence of thyroid disease (12.9%, P vitiligo. We observed a high prevalence of comorbid autoimmune diseases in patients with vitiligo and report several new associations. Copyright © 2015 American Academy of Dermatology, Inc.

    Norrie disease (ND) is an X-linked recessive disorder characterized by congenital blindness, progressive sensorineural hearing loss and cognitive impairment. The ocular phenotype has been well described, while the extraocular manifestations of the disorder are not well understood. We present the data from the Norrie Disease Registry, which consists of 56 patients with detailed clinical histories and genotype data. This study represents the largest, detailed investigation into the phenotypic spectrum of ND to date and more importantly expands knowledge of the extraocular clinical manifestations. We identify several novel aspects of the syndrome that will improve the management of these patients. In particular, we expand our understanding of the neurologic manifestations in ND and identify a chronic seizure disorder in approximately 10% of all patients. In addition, details of the hearing phenotype are described including the median age of onset (12 years of age) and how genotype affects onset. Moreover, we find vascular disease to be a significant component of ND; and vascular health should be, in the future, a component of patient clinical care. In summary, the results expand our understanding of the phenotypic variability and genotypic heterogeneity in ND patients. Copyright © 2012 Wiley Periodicals, Inc.

    2002-01-01

    In this era of processes and systems to improve quality, disease management is one methodology to improve care delivery and outcomes for patients with chronic kidney disease (CKD). In most disease management systems a senior renal nurse coordinates all aspects of the patient's care and ensures that the prescribed and necessary care is delivered for both CKD-related and comorbid conditions. The nurse also continually monitors outcomes on quality indicators and key performance measures. These outcome data are then aggregated and analyzed, are compared with local and national benchmarks, and drive the continuous quality improvement (CQI) process. Such a system attempts to centralize the currently fragmented care delivery system, continually improve patient outcomes, and conserve scarce economic resources. Early data suggest a disease management approach may improve both the morbidity and mortality of CKD patients.

    Celiac disease shares features of other disorders. It can be diagnosed conclusively only based on duodenal histology analysis, which is not practical for screening purposes. Serologic analysis might be used to identify candidates for biopsy analysis. We aimed to develop a simple diagnostic approach that all clinicians could follow to increase the percentage of patients accurately diagnosed with celiac disease at initial presentation. We performed a retrospective analysis of data from 752 patients (88 with celiac disease, none were IgA deficient) who attended a UK district general hospital from January 2007 through December 2008 and underwent biopsy analysis and serologic tests to measure endomyseal antibodies and IgA antibodies against tissue transglutaminase (tTG). Patients avoiding gluten in their diet were excluded. Patients were assigned to 1 of 4 groups: high-risk (based on presence of anemia, chronic diarrhea, unintentional weight loss, or dermatitis herpetiformis), low-risk (based on such factors as dyspepsia, abnormal liver function, ataxia, or chronic cough), nutrient deficiency (based on levels of iron, vitamins B12 and D, or folate), or screening (because they had type 1 diabetes or a family history of celiac disease). Patients with celiac disease were identified using the modified Marsh criteria (grades 1-3) for interpreting duodenal histology. We compared clinical category, serology profiles, and biopsy results between patients with and without celiac disease. Celiac disease was diagnosed in 64 of 565 patients in the high-risk group (11%), 14 of 156 patients in the low-risk group (9%; P = .47 compared with high-risk group), 7 of 28 patients in the nutrient-deficiency group, and 3 of 3 patients in the screening group. Among 71 patients who tested positive for both antibodies (tTG and endomyseal antibodies), the positive predictive value for celiac disease was 97%; a negative test result for tTG had a negative predictive value of 98%. Among 708 patients

    This study sought to determine the prevalence of malnutrition in patients with inflammatory bowel disease, to analyse the dietary beliefs and behaviours of these patients, to study their body composition, to evaluate their muscular strength and to identify the factors associated with malnutrition in these patients. This was a prospective, multicentre study. Crohn's disease and ulcerative colitis patients from 30 Spanish centres, from the outpatient clinics, were included. A questionnaire of 11 items was applied to obtain data from patients' dietary behaviour and beliefs. Patients who accepted were evaluated to assess their nutritional status using Subjective Global Assessment and body mass index. Body composition was evaluated through bioelectrical impedance. A total of 1271 patients were included [51% women, median age 45 years, 60% Crohn's disease]. Of these, 333 patients underwent the nutritional evaluation. A total of 77% of patients declared that they avoided some foods to prevent disease relapse. Eighty-six per cent of patients avoided some foods when they had disease activity because of fear of worsening the flare. Sixty-seven per cent of patients modified their dietary habits after disease diagnosis. The prevalence of malnutrition was 16% [95% confidence interval = 12-20%]. In the multivariate analysis, history of abdominal surgery, active disease and avoidance of some foods during flares were associated with higher risk of malnutrition. The prevalence of malnutrition in inflammatory bowel disease patients was high. We identified some predictive factors of malnutrition. Most of the patients had self-imposed food restrictions, based on their beliefs. Copyright © 2017 European Crohn’s and Colitis Organisation (ECCO). Published by Oxford University Press.

    Dementia and other neurodegenerative diseases cause profound declines in functioning; thus, many patients require caregivers for assistance with daily living. Patients differ greatly in how long they live after disease onset, with the nature and severity of the disease playing an important role. Caregiving can also be extremely stressful, and many caregivers experience declines in mental health. In this study, we investigated the role that caregiver mental health plays in patient mortality. In 176 patient-caregiver dyads, we found that worse caregiver mental health predicted greater patient mortality even when accounting for key risk factors in patients (i.e., diagnosis, age, sex, dementia severity, and patient mental health). These findings highlight the importance of caring for caregivers as well as patients when attempting to improve patients' lives.

    Patient education plays an important role in chronic disease management. The aim of this study is to identify patients' preferences in regard to the design features of effective online patient education (OPE) and the benefits. A review of the existing literature was conducted in order to identify the benefits of OPE and its essential design features. These design features were empirically tested by conducting survey with patients and caregivers. Reliability analysis, construct validity and regression analysis were performed for data analysis. The results identified patient-tailored information, interactivity, content credibility, clear presentation of content, use of multimedia and interpretability as the essential design features of online patient education websites for chronic disease management.

    Quality of life (QoL) and life satisfaction (LS) are important outcome factors in chronic inflammatory conditions such as Behçet's disease (BD). The aim of this study was to investigate QoL and LS in patients with BD and determine the relationship with disease activity. Forty-one patients with BD and 40 control subjects were involved in the study. Demographic properties were obtained. Disease activity was assessed by Turkish version of BD Current Activity Form (BDCAF) in BD patients. QoL and psychological well-being were assessed by Nottingham Health Profile (NHP) and Life Satisfaction Index (LSI), respectively, in both patients and control groups. The related disease activity measures of QoL and LS were determined. Twenty-two male and 19 female BD patients with a mean age of 33.3+/-9.3 years and 20 male and 20 female control subjects with a mean age of 33.3+/-4.1 years were involved. According to BDCAF, no patient had central nervous system involvement. Thirty-four patients had headache, 33 patients had fatigue, 30 patients had articular involvement, 29 had mucocutaneous lesions, 27 had gastrointestinal involvement, 21 patients had ocular involvement, and 7 patients had vascular involvement. The scores of all dimensions of NHP were significantly higher and the mean score of LSI was significantly lower in BD patients than in control subjects (pimpression of disease activity and joint involvement. In conclusion, patients with BD have impaired QoL and disturbed psychological well-being. Current management strategies focusing on fatigue, arthralgia, mucocutaneous lesions, and efforts to measure psychosocial aspects and symptoms of the patients by their point of view will help to improve QoL and raise the LS in patients suffering from BD.

    Cardiovascular disease constitutes the major cause of mortality in patients with chronic kidney disease. Arterial stiffness is an important contributor to the occurrence and progression of cardiovascular disease. Various risk factors, including altered hormone levels, have been suggested to be associated with arterial stiffness. Based on the background that chronic kidney disease predisposes individuals to a wide range of hormonal changes, we herein review the available data on the association between arterial stiffness and hormones in patients with chronic kidney disease and summarize the data for the general population.

    Patient dependence has rarely been studied in mild-to-moderate Alzheimer's disease (AD). To identify factors which predict patient dependence in mild-to-moderate AD. We studied 398 non-institutionalized AD patients (234 females) of the ongoing Prospective Registry on Dementia (PRODEM) in Austria. The Dependence Scale (DS) was used to assess patient dependence. Patient assessment comprised functional abilities, neuropsychiatric symptoms and cognitive functions. A multiple linear regression analysis was performed to identify predictors of patient dependence. AD patients were mildly-to-moderately impaired (mean scores and SDs were: CDR 0.84 ± 0.43; DAD 74.4 ± 23.3, MMSE = 22.5 ± 3.6). Psychopathology and caregiver burden were in the low range (mean NPI score 13.2, range 0 to 98; mean ZBI score 18, range 0-64). Seventy five percent of patients were classified as having a mild level of patient dependence (DS sum score 0 to 6). Patient dependence correlated significantly and positively with age, functional measures, psychopathology and depression, disease duration, and caregiver burden. Significant negative, but low correlations were found between patient dependence, cognitive variables, and global cognition. Activities of daily living, patient age, and disease severity accounted for 63% of variance in patient dependence, whereas cognitive variables accounted for only 11%. Dependence in this cohort was mainly related to age and functional impairment, and less so to cognitive and neuropsychiatric variables. This differs from studies investigating patients in more advanced disease stages which found abnormal behavior and impairments of cognition as main predictors of patient dependence.

    The periodontal disease during pregnancy of women with rheumatic valve disease imply infective endocarditis risks and higher rate of preterm birth and low birth weight. To study the periodontal disease rate of women with rheumatic valve disease during pregnancy. We studied 140 pregnant women who included 70 patients with rheumatic valve disease and 70 healthy women. The periodontal examination included: 1) periodontal clinical exam regard the follow variables: a) probing depth; b) gingival margin; c) clinical attachment level; d) bleeding on probing; e) plaque index and f) gingival index; and 2) microbiological test was performed in samples serum and gingival crevicular fluid and considered positive controls to Porphyromonas gingivalis, Tannerella forsithia e Aggregobacter actinomycetemcomitans. Age and parity were similar between groups; as single or combined the mitral valve disease was prevalent among the rheumatic valve lesion in 45 (32.1%) e 20 (28.5%) cases, respectively. Among the periodontal variables gingival margin (p=0.01) and plaque index (p=0.04) were different between groups. The periodontal disease was identified in 20 (14,3%) pregnant women, seven (10%) of them were patients with valve rheumatic disease and the remain 13 (18,6%) were healthy women, its percentual was not different between groups (p=0,147). Microbiological analyses of oral samples showed higher percentual of P. gingivalis in healthy pregnant women (p=0.004). The clinical and microbiological study during pregnancy showed comparable incidence of periodontal disease between women with rheumatic valve disease and healthy women.

    Celiac disease is an autoimmune disorder that is known specifically for causing inflammation of the mucosa in the small intestine. Through multiple diagnostic and screening tools such as small intestinal biopsy sample, serological testing, and human leukocyte antigen testing, healthcare providers can diagnose this disease that contains components related to genetic predisposition and intake of gluten proteins found in wheat, barley, and rye. There are some who believe that having an autoimmune disease may predispose one to acquiring another disease. With patients experiencing mostly diarrhea, abdominal pain, and weight loss, the implementation of a gluten-free diet is the treatment that healthcare providers recommend. Through monitoring gluten intake and providing nutritional supplementation, those diagnosed with celiac disease can lead a relatively normal life without complications. With celiac disease affecting all age ranges in the population, and with a documented higher frequency, there is a growing awareness in society that can be easily seen in grocery stores, restaurants, and food manufacturers.

    To determine the percentage of Lyme patients with articular manifestations in NW Spain and to know their evolution and response to treatment. A retrospective study (2006-2013) was performed using medical histories of confirmed cases of Lyme disease showing articular manifestations. Clinical and laboratory characteristics, together with the treatment and evolution of the patients, were analysed. Seventeen out of 108 LD confirmed patients (15.7%) showed articular manifestations. Regarding those 17 patients, 64.7%, 29.4% and 5.9% presented arthritis, arthralgia and bursitis, respectively. The knee was the most affected joint. Articular manifestations were often associated to neurological, dermatological and cardiac pathologies. Otherwise, most patients were in Stage III. The 11.8% of the cases progressed to a recurrent chronic arthritis despite the administration of an appropriate treatment. Lyme disease patients showing articular manifestations should be included in the diagnosis of articular affections in areas of high risk of hard tick bite, in order to establish a suitable and early treatment and to avoid sequels.

    2017-12-01

    Heart failure (HF) is a leading cause of morbidity and mortality in patients with chronic kidney disease (CKD), and the population of CKD patients with concurrent HF continues to grow. The accurate diagnosis of HF is challenging in patients with CKD in part due to a lack of validated imaging and biomarkers specifically in this population. The pathophysiology between the heart and the kidneys is complex and bidirectional. Patients with CKD have greater prevalence of traditional HF risk factors as well as unique kidney-specific risk factors including malnutrition, acid-base alterations, uraemic toxins, bone mineral changes, anemia and myocardial stunning. These risk factors also contribute to the decline of kidney function seen in patients with subclinical and clinical HF. More targeted HF therapies may improve outcomes in patients with kidney disease as current HF therapies are underutilised in this population. Further work is also needed to develop novel HF therapies for the CKD population. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Anemia of chronic diseases (ACD) is a common problem in patients with infectious diseases and can influence the quality of life and patients' survival. Despite the clinical importance of ACD, data are still lacking regarding this problem in the infectious diseases. This study aimed to evaluate the prevalence, related factors, outcome and approaches to anemia in the infectious diseases ward. This retrospective study was performed to review the medical records of patients admitted to the infectious diseases department of Imam Khomeini hospital during a two-year period between 2009 and 2011. A standard protocol was developed to evaluate anemia. Patients' demographic data approaches to manage anemia and routine laboratory tests were recorded and compared with the protocol. Totally, 1,120 medical records were reviewed. ACD was recognized in 705 patients (63%). Only 5.1% of diagnostic and 8.7% of treatment approaches was based on the protocol. The majority of patients (89.4%) were received inappropriate treatment regarding. Mortality rate of patients with ACD was 3.4%. Moreover, a significant correlation between anemia and mortality was detected (r = 0.131; p = 0.026). A statistically significant correlation was also identified between patients' Hgb and ESR, CRP, reasons of admission, number of medications, and underlying diseases. In conclusion, results of this study suggested that ACD is a common problem in infectious diseases patients and significantly associated with patients' mortality. Moreover, the majority of studied patients were not received an appropriate diagnostic and treatment approach which arises more concerns regarding the management of ACD in infectious diseases setting.

    Patients with chronic illnesses such as Inflammatory Bowel Disease (IBD) have been more keen to utilize the Internet and in particular, social media to obtain patient educational information in recent years. It is important for the gastroenterologist to be aware of these modalities and how they might affect information exchange and ultimately, disease management. This article addresses the current prevalence of social media use, advent of mobile health applications, social media usage in patients with chronic conditions, usage amongst providers, and most notably, the usage and preferences in IBD patients. Over the last decade there has been an increasing desire from patients to receive educational material about their disease through social media. We reviewed the medical literature on the quality of IBD-related information on social media. Given the disparity of information available on the Internet, we remark on the quality of this information and stress the need for further research to assess the validity of IBD information posted on social media.

    Patients with gastroesophageal reflux disease (GERD) have decreased health-related quality of life (HRQL). The quality of life in patients with laryngopharyngeal reflux (LPR) symptoms is also significantly impaired. However, the impact of LPR symptoms on HRQL in GERD patients has not been studied. A nationwide, random-sample, and face-to-face survey of 300 Korean patients with GERD was conducted from January to March 2013. Gastroesophageal reflux symptoms were assessed using the Rome III questionnaire, LPR symptoms using the reflux symptom index, and HRQL using the EuroQol five dimensions (EQ-5D) questionnaire. A structured questionnaire on patient satisfaction, sickness-related absences, and health-related work productivity was also used. Among the 300 patients with GERD, 150 had LPR symptoms. The mean EQ-5D index was lower in patients with GERD and LPR symptoms than in those without LPR (0.88 vs 0.91, P = 0.002). A linear regression model showed that the severity of LPR symptoms was related to decreased HRQL and was independent of age, marital status, body mass index, or household income. The overall satisfaction rate regarding treatment was lower in patients with GERD and LPR (40.0% vs 69.1%, P = 0.040). GERD patients with LPR symptoms reported greater sickness-related absent hours per week (0.36 vs 0.02 h, P = 0.016) and greater percentages of overall work impairment than those without LPR (31.1% vs 20.8%, P Gastroesophageal reflux disease patients with LPR symptoms have a poorer HRQL, a lower satisfaction rate, and a greater disease burden than those without LPR. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    Full Text Available Although neuromyelitis optica (NMO is known to be a more severe disease than relapsing-remitting multiple sclerosis (RRMS, few studies comparing both conditions in a single center have been done. Methods: Comparison of our previously published cohort of 41 NMO patients with 177 RRMS patients followed in the same center, from 1994 to 2007. Results: Mean age of onset was 32.6 for NMO and 30.2 for RRMS (p=0.2062 with mean disease duration of 7.4 years for NMO and 10.3 years for RRMS. Patients with NMO had a higher annualized relapse rate (1.0 versus 0.8, p=0.0013 and progression index (0.9 versus 0.6, p≪0.0001, with more patients reaching expanded disability status scale (EDSS 6.0 (39 versus 17%, p=0.0036. The odds ratio for reaching EDSS 6.0 and being deceased due to NMO in comparison to RRMS were, respectively, 3.14 and 12.15. Conclusion: Patients with NMO have a more severe disease than patients with RRMS, including higher risk of dying of a demyelinating disease.

    The supply of vitamins and microelements in patients with chronic kidney disease (CKD) is very important and requires special attention. CKD patients presented deficiency of these substances in the diet and in organism, but also excess of fat-soluble vitamins or trace elements is observed. Studies indicate that deficiency of vitamins and antioxidants in diet and also enhanced oxidative stress are cause of many complications for example: accelerated process of arteriosclerosis in patients with chronic kidney disease.

    Endocarditis has been reported in patients with valvular heart disease who have undergone acupuncture treatment, although most have been associated with the use of semi-permanent needles. This has led reviewers to suggest that acupuncture may not only be contraindicated in such patients but that prophylactic antibiotics should be given. This study investigated the use of acupuncture treatment in patients with proven valvular heart disease and observed whether endocarditis developed in such patients. All patients in a single-handed GP practice with proven valvular heart disease, including those with prosthetic valves, were identified over a ten-year period. Those who had undergone acupuncture treatment underwent a clinical examination and diagnostic tests, which focused on the signs, symptoms and laboratory criteria for the diagnosis of endocarditis and included a transthoracic echocardiogram. Autopsy findings were reviewed in any patient who died. Based on these clinical and laboratory data, using the modified Duke's criteria for the diagnosis of endocarditis, patients were identified as having definite or possible endocarditis, or the diagnosis was rejected. All patients underwent brief acupuncture with no skin disinfectant and no prophylactic antibiotics were given. Semi-permanent needles were avoided. Thirty-six patients with valvular heart disease underwent a total of 479 acupuncture treatments over a ten-year period. The median number of treatments was 9 (range 1-72), with a follow-up after treatment of 5.75 years (range 0.5-10 years). Definite endocarditis was not found in any patient, but two patients had possible endocarditis, eventually discounted by both negative blood cultures and echocardiography. In conclusion, brief acupuncture was safe in this small cohort of valvular heart disease patients and no case of endocarditis was detected over a ten-year period.

    Gastrointestinal diseases constitute the second most common group conditions affecting HIV-positive patients after respiratory diseases. Gastrointestinal involvement may even be the first sign of the disease, a facto which demonstrates the importance of its proper assessment. To demonstrate the utility of computed tomography and ultrasound in the study of gastrointestinal and hepatobiliary diseases in the HIV-positive patient. We review a series of 85 HIV-positive patients presenting gastrointestinal symptomatology who underwent ultrasonography and/or computed tomography. the definitive diagnosis was achieved in all the patients by microbiological or histopathological means. In our series 36.4% the patients had presented systemic TB, 23.52% CMV infection, 17.64% Cryptosporidium infection and 17.64% MAI infection. Much lower incidences were found for Mycobacterium xenopi. M. kansai and Leishmania infection. The presence of lymphoma was confirmed in 7.05% of the patients and Koposi's sarcoma in 0.95%. In these patients, the most common finding on imaging studies in lymph node involvement, followed by diffuse hepatosplenomegaly. Imaging techniques, especially ultrasonography and computed tomography, are useful in these patients: although they do not provide the diagnosis, they do contribute data of prognostic and therapeutic importance.

    Niemann-Pick disease (NPD) is a neurovisceral lysosomal storage disorder caused by acid sphingomyelinase (ASM) deficiency, which can be categorized as either Niemann-Pick disease type A [NPD-A], with progressive neurological disease and death in early childhood, or as Niemann-Pick disease type B [NPD-B], with a more variable spectrum of manifestations. Enzyme replacement therapy (ERT) with recombinant sphingomyelinase is currently studied as potential treatment for NPD-B patients. The objective of this study is to characterize the clinical features of patients with ASM deficiency in the Netherlands and Belgium with focus on the natural disease course of NPD-B patients. Prospective and retrospective data on ASM deficient patients were collected in The Netherlands and part of Belgium. Patients with NPD-B that could be followed prospectively were evaluated every 6-12 months for pulmonary function tests, 6 minute walk test (6 MWT), imaging (bone marrow infiltration measured by QCSI, organ volumes by MRI and CT scan of the lungs) and biochemical markers. Twenty-five patients with ASM deficiency were identified (13 males, 12 females, median age 13years, range 1-59 years). Nine patients had died at the time of the study, including four NPD-A patients at the age of 1,1, 2, 3 and five NPDB patents at the age of 5, 6, 43, 56 and 60 years. There was a high prevalence of homozygosity and compound heterozygosity for the common p.Arg608del mutation in 43% and 19% of NPD-B patients, respectively. In NPD-B patients, thrombocytopenia was present in most, while anemia and leucopenia were less common (33% and 6 % respectively). HDL cholesterol was reduced in most patients. Pulmonary disease was severe in several patients. Follow-up up to 11 years revealed a gradual decrease in platelet count. Detailed investigations in 6 NPD-B patients with follow-up in 4 patients revealed remarkable stable disease parameters up to 6 years, with some decline in pulmonary function and 6 MWT. Bone

    Several studies have reported an association between chronic obstructive pulmonary disease (COPD) and periodontal diseases. However, a large-scale population-based cohort study was previously absent from the literature. Therefore, we evaluated the risk of periodontal diseases in patients with COPD in a nationwide population.From the National Health Insurance claims data of Taiwan, we identified 22,332 patients with COPD who were newly diagnosed during 2000 to 2010. For each case, two individuals without COPD were randomly selected and frequency matched by age, sex, and diagnosis year. Both groups were followed up till the end of 2011.The overall incidence of periodontal diseases was 1.19-fold greater in the COPD group than in the comparison group (32.2 vs 26.4 per 1000 person-years; 95% confidence interval [CI] 1.15-1.24). Compared with non-COPD patients, the adjusted hazard ratios of patients with COPD increased with the number of emergency room visits (from 1.14 [95% CI 1.10-1.19] to 5.09 [95% CI 4.53-5.72]) and admissions (from 1.15 [95% CI 1.10-1.20] to 3.17 [95% CI 2.81-3.57]). In addition, the adjusted hazard ratios of patients with COPD treated with inhaled corticosteroids (1.22, 95% CI 1.11-1.34) and systemic corticosteroids (1.15, 95% CI 1.07-1.23) were significantly higher than those of patients not treated with corticosteroids.Patient with COPD are at a higher risk of developing periodontal diseases than the general population. Our results also support that the risk of periodontal diseases is proportional to COPD control. In addition, patients who receive corticosteroid treatment are at a higher risk of developing periodontal diseases.

    BACKGROUND: The encephalopathy associated with autoimmune thyroid disease (EAATD) is characterized by neurological\\/psychiatric symptoms, high levels of anti-thyroid antibodies, increased cerebrospinal fluid protein concentration, non-specific electroencephalogram abnormalities, and responsiveness to the corticosteroid treatment in patients with an autoimmune thyroid disease. Almost all EAATD patients are affected by Hashimoto\\'s thyroiditis (HT), although fourteen EAATD patients with Graves\\' disease (GD) have been also reported. METHODS: We have recorded and analyzed the clinical, biological, radiological, and electrophysiological findings and the data on the therapeutic management of all GD patients with EAATD reported so far as well as the clinical outcomes in those followed-up in the long term. RESULTS: Twelve of the fourteen patients with EAATD and GD were women. The majority of GD patients with EAATD presented with mild hyperthyroidism at EAATD onset or shortly before it. Active anti-thyroid autoimmunity was detected in all cases. Most of the patients dramatically responded to corticosteroids. The long term clinical outcome was benign but EAATD can relapse, especially at the time of corticosteroid dose tapering or withdrawal. GD and HT patients with EAATD present with a similar clinical, biological, radiological, and electrophysiological picture and require an unaffected EAATD management. CONCLUSIONS: GD and HT equally represent the possible background condition for the development of EAATD, which should be considered in the differential diagnosis of all patients with encephalopathy of unknown origin and an autoimmune thyroid disease, regardless of the nature of the underlying autoimmune thyroid disease.

    BACKGROUND: The encephalopathy associated with autoimmune thyroid disease (EAATD) is characterized by neurological\\/psychiatric symptoms, high levels of anti-thyroid antibodies, increased cerebrospinal fluid protein concentration, non-specific electroencephalogram abnormalities, and responsiveness to the corticosteroid treatment in patients with an autoimmune thyroid disease. Almost all EAATD patients are affected by Hashimoto\\'s thyroiditis (HT), although fourteen EAATD patients with Graves\\' disease (GD) have been also reported. METHODS: We have recorded and analyzed the clinical, biological, radiological, and electrophysiological findings and the data on the therapeutic management of all GD patients with EAATD reported so far as well as the clinical outcomes in those followed-up in the long term. RESULTS: Twelve of the fourteen patients with EAATD and GD were women. The majority of GD patients with EAATD presented with mild hyperthyroidism at EAATD onset or shortly before it. Active anti-thyroid autoimmunity was detected in all cases. Most of the patients dramatically responded to corticosteroids. The long term clinical outcome was benign but EAATD can relapse, especially at the time of corticosteroid dose tapering or withdrawal. GD and HT patients with EAATD present with a similar clinical, biological, radiological, and electrophysiological picture and require an unaffected EAATD management. CONCLUSIONS: GD and HT equally represent the possible background condition for the development of EAATD, which should be considered in the differential diagnosis of all patients with encephalopathy of unknown origin and an autoimmune thyroid disease, regardless of the nature of the underlying autoimmune thyroid disease.

    Coping is an integral part of adjustment for patients with Inflammatory Bowel Disease but has not been well described in the literature. This study explored the relationship between coping, perceived health competence, patient preference for involvement in their treatment, depression and quality of life, particularly among patients with inactive disease (in remission). Subjects (n=70) with active and inactive IBD completed questionnaires, including the Inflammatory Bowel Disease Quality of Life Questionnaire, Beck Depression Inventory, Perceived Health Competence Scale and the Coping Inventory for Stressful Situations. The Harvey Bradshaw Index measured disease activity. Patients with inactive IBD demonstrated significantly more interest in participating in their treatment (pperceived health competence (p=.001), less depressive symptoms (pperceived control of their health, and exhibit less depression symptoms. Our findings may increase awareness of the importance of identifying coping strategies for IBD patients, including those in remission. © 2013.

    Lee, Ruth

    2012-02-01

    PURPOSE OF REVIEW: Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) represent two of the most prevalent chronic respiratory disorders and cardiovascular diseases are major co-morbidities in both. Co-existence of both disorders (overlap syndrome) occurs in 1% of adults and overlap patients have worse nocturnal hypoxemia and hypercapnia than COPD and OSA patients alone. The present review discusses recent data concerning the pathophysiological and clinical significance of the overlap syndrome. RECENT FINDINGS: The severity of obstructive ventilatory impairment and hyperinflation, especially the inspiratory capacity to total lung capacity (TLC) ratio, correlates with the severity of sleep-related breathing disturbances. Early treatment with continuous positive airway pressure (CPAP) improves survival, reduces hospitalization and pulmonary hypertension, and also reduces hypoxemia. Evidence of systemic inflammation and oxidative stress in COPD and sleep apnea provides insight into potential interactions between both disorders that may predispose to cardiovascular disease. Long-term outcome studies of overlap patients currently underway should provide further evidence of the clinical significance of the overlap syndrome. SUMMARY: Studies of overlap syndrome patients at a clinical, physiological and molecular level should provide insight into disease mechanisms and consequences of COPD and sleep apnea, in addition to identifying potential relationships with cardiovascular disease.

    Full Text Available We studied xerostomy and its correlation with periodontal and dental cavity diseases in HIV patients, through measurement of salivary flow and through variables such as saliva buffer capacity, salivary pH, periodontal index, MDF index, dental carie risk and risk of periodontal disease. One hundred patients were analyzed. They were distributed into two groups: Group I (test - 50 patients evidently HIV+, from whom information was collected and analyzed regarding age, gender, skin color, habits, general and oral diseases, levels of T-CD4 lymphocytes, viral load and highly active antiretroviral therapy (HAART; and Group II - (control 50 HIV- patients, from whom information was collected and analyzed regarding age, gender, skin color, habits, general and oral diseases. In both groups, measurement of salivary flow, pH and buffer capacity was made. Group I presented high MDF, bacteria plaque and bleeding, with a greater susceptibility to the risks of oral cavities and periodontal disease. The salivary flow and the buffering capacity of the saliva were low, indicating a high level of xerostomy. Two important modifying factors influence these pathologies in an incisive way: one is immunossuppression and the other is HAART therapy. The control exhibited results that are closer to normality; it had better oral-health conditions.

    The seroepidemiology of Leptospira infection in patients suffering from liver disease has been poorly studied. Information about risk factors associated with infection in liver disease patients may help in the optimal planning of preventive measures. We sought to determine the association of Leptospira IgG seroprevalence and patients with liver diseases, and to determine the characteristics of the patients with Leptospira exposure. We performed a case-control study of 75 patients suffering from liver diseases and 150 age- and gender-matched control subjects. Diagnoses of liver disease included liver cirrhosis, steatosis, chronic hepatitis, acute hepatitis, and amoebic liver abscess. Sera of participants were analyzed for the presence of anti- Leptospira IgG antibodies using a commercially available enzyme immunoassay. Anti-Leptospira IgG antibodies were found in 17 (22.7%) of 75 patients and in 15 (10.0%) of 150 control subjects (OR = 2.32; 95% CI: 1.09-4.94; P=0.03). This is the first age- and gender-matched case control study about Leptospira seroprevalence in patients with liver diseases. Results indicate that Leptospira infection is associated with chronic and acute liver diseases. Results warrants for additional studies on the role of Leptospira exposure in chronic liver disease.

    The strong association between congenital heart disease and spinal deformity is well established, but data on the risks and outcome of spinal fusion surgery in patients with congenital heart disease are scarce. The purpose of this study was to identify predictors of perioperative risk and outcome in a large series of children and adolescents with congenital heart disease who underwent spinal fusion for scoliosis or kyphosis. In the authors' retrospective analysis of 74 consecutive patients with congenital heart disease undergoing spinal fusion, there were two deaths (2.7%) and 18 significant complications (24.3%) in the perioperative period. Preoperative cyanosis (arterial oxygen saturation < 90% at rest) with uncorrected or incompletely corrected congenital heart disease was associated with both deaths. Complications occurred in nine of 18 (50%) patients with cyanosis and in 11 of 56 (20%) patients without cyanosis. As judged by multivariate analysis the best predictors of perioperative outcome were the overall physical status of the patient as represented by the American Society of Anesthesiologists' preoperative score and a higher rate of intraoperative blood loss. Seventeen of 43 patients (40%) with an American Society of Anesthesiologists score of 3 or higher experienced complications including two perioperative deaths. Successful spinal fusion and correction were achieved in 97% of patients. Children and adolescents with congenital heart disease can undergo elective spinal fusion with risks that relate to overall cardiac status. Careful assessment of preoperative status by pediatric cardiologists and cardiac anesthesiologists familiar with surgical treatment of patients with congenital heart disease will assist the orthopaedic surgeon in providing the most realistic estimate of risk.

    Objective: To investigate the clinical Significance of determination of serum thyroid stimulating hormone receptor antibody (TRAb) levels in patients with thyroid diseases, especially in patients with Graves' disease. Methods: Serum TRAb levels were determined with radio-receptor assay (RRA) in 302 patients with various thyroid diseases and 52 controls. Results: In patients with Graves' disease before treatment (n=62) the positive rate of TRAb was 86.3%. In patients with Graves' diseases improved after treatment (n=60), the positive rate was 74.5%; in those clinically cured (n=68) the positive rate was 32.1%. In 58 patients with Graves' disease who relapsed after apparently cure, the positive rate of TRAb rose to 90.3 %. However, there were no positive TRAb cases in 23 patients with simple goiter and 31 patients with benign thyroid adenomas. Also, there were no positive TRAb cases in the controls. Conclusion: TRAb levels correspond well with the severity of Graves' disease. (authors)

    Excessive flatulence which impairs social performance in patients is one of the common reasons for referrals to gastroenterology clinics. Celiac Disease is a rare but important cause of increased intestinal gas (bloating) and if not diagnosed, patients face complications such as malabsorption, anemia, osteoporosis and even intestinal lymphoma. This study aimed to determine the frequency of Celiac Disease in patients with excessive flatulence. One hundred and fifty patients with a chief complaint of experiencing flatulence more than 15 times a day and lasting for three months were referred to the gastroenterology clinic of Rasoul-e-Akram Teaching Hospital. Serological tests for Celiac Disease, Anti TTG Ab (IgA-IgG) were requested and the patients with positive tests underwent upper GI endoscopy. Biopsies of the second part of the duodenum were then sent to the laboratory. From one hundred and thirty patients who completed the study, 92 (70.7%) were female. Mean age of the patients was 32 ± 13 years. Anti TTG Ab was found in 5 patients (3.85%). Only 2 patients (1.5%) had a documented positive pathology for Celiac Disease. According to the results of this study and other studies, we conclude that Celiac Disease is an uncommon etiology for excessive flatulence but it is of importance to investigate it in excessive flatulence patients.

    Menkes disease (MNK) is an X-linked recessive disorder. Incidence of live-born infants with MNK is 2.8 per million live births in Japan. The aim of this study was to observe congenital malformations (CMs) in MNK patients. Subjects comprised 35 Japanese male patients with classical MNK who received copper histidine treatment. Patient clinical data were obtained anonymously from medical records or medical record summaries by pediatrician's retrospective review through a survey. We observed 21 different CMs in 14 patients. Eight of these had a single CM, while six had multiple CMs. The most frequent CM was higher arched palate with other CMs found in five patients. There was no relationship between CMs and mutations in the ATP7A gene. Using Mann-Whitney U tests, age at death was also significantly lower in MNK patients with CMs (Pheart disease, and one with microphallus. Copyright © 2012 The Japanese Society of Child Neurology.

    Full Text Available The study aimed to investigate the basic aspects of quality of life and relation to disease in patients with malignant or premalignant bone tumors. Study participants (N=82 were aged 18 to 67 years (average age 34 ± 2 years. They were separated into three groups depending on diagnosis: patients with osteosarcoma, patients with giant cell tumor and patients with chondrosarcoma. The SF-36 Health Status Survey and the Quality of Life Questionnaire - Core 30 with Bone Metastasis (BM22 Module were used to assess patient quality of life. The type of relation to disease method (TOBOL was used to determine the relation to disease of the patients. According to the results of the quality of life study, patients with giant cell tumor exhibited the highest degree of limiting physical activity and reduced social functioning, the greatest financial difficulties and more pain sites than either patients with osteosarcoma or patients with chondrosarcoma. The study of relation to disease revealed that all studied groups of patients were susceptible to ergopathic and sensitive types of relation to disease. Moreover, patients with giant cell tumor experienced increased levels of tension and irritability with respect to relation to disease and treatment, while patients with chondrosarcoma were more susceptible to anxiety and hypochondria with respect to relation to disease. Patients with different types of bone tumors have different experiences with respect to their physical and mental health, their social functioning and their general health. The results of the study may be useful in developing individualized psychological aid programs for patients with malignant and premalignant bone tumors.

    Full Text Available John J HalperinDepartment of Neurosciences, Overlook Medical Center, Summit, NJ, USAAbstract: Lyme disease, infection with the tick-borne spirochete Borrelia burgdorferi, causes both specific and nonspecific symptoms. In untreated chronic infection, specific manifestations such as a relapsing large-joint oligoarthritis can persist for years, yet subside with appropriate antimicrobial therapy. Nervous system involvement occurs in 10%–15% of untreated patients and typically involves lymphocytic meningitis, cranial neuritis, and/or mononeuritis multiplex; in some rare cases, patients have parenchymal inflammation in the brain or spinal cord. Nervous system infection is similarly highly responsive to antimicrobial therapy, including oral doxycycline. Nonspecific symptoms such as fatigue, perceived cognitive slowing, headache, and others occur in patients with Lyme disease and are indistinguishable from comparable symptoms occurring in innumerable other inflammatory states. There is no evidence that these nonspecific symptoms reflect nervous system infection or damage, or that they are in any way specific to or diagnostic of this or other tick-borne infections. When these symptoms occur in patients with Lyme disease, they typically also subside after antimicrobial treatment, although this may take time. Chronic fatigue states have been reported to occur following any number of infections, including Lyme disease. The mechanism underlying this association is unclear, although there is no evidence in any of these infections that these chronic posttreatment symptoms are attributable to ongoing infection with B. burgdorferi or any other identified organism. Available appropriately controlled studies indicate that additional or prolonged courses of antimicrobial therapy do not benefit patients with a chronic fatigue-like state after appropriately treated Lyme disease. Keywords: Lyme disease, Borrelia burgdorferi, chronic, diagnosis, treatment, chronic

    1995-01-01

    Full Text Available Previous reports have suggested that autoimmune thyroid disorders (including Hashimoto’s or lymphocytic thyroiditis may occur in patients with celiac disease. In this study, the prevalence of thyroid disease was explored in a series of 96 consecutive patients seen with biopsy-defined adult celiac disease (average age 47.3 years. Sixteen celiac patients (average age 58.1 years were detected with hypothyroidism, including four treated with radio-iodine ablation or thyroidectomy for Grave’s disease. In addition to celiac disease, almost half had dermatitis herpetiformis, a small intestinal neoplasm (particularly lymphoma or both. Diagnosis of thyroid disease preceded diagnosis of celiac disease in 13 patients or was made concurrently in two patients. In only one patient was thyroid disease detected after celiac disease was diagnosed. This indicates that thyroid diseases occur more commonly in celiac disease than is currently appreciated, possibly due to shared embryological origins or common immunopathological features, and may be the presenting clinical manifestation in adults especially if there is coexistent dermatitis herpetiformis. Careful monitoring of this subgroup may be warranted because of the frequency of neoplastic intestinal diseases, particularly lymphoma.

    The prevalence of metabolic syndrome (MS) in patients with peripheral arterial disease (PAD) and coronary or cerebrovascular disease is increasing, but it is not known whether this association also exists in patients with isolated PAD. The aim of the current study was to assess the prevalence of MS in patients with PAD who had no coronary or cerebrovascular disease, the prescription rate of evidence-based cardiovascular therapies and the attainment of therapeutic goals in patients with PAD and with and without MS. Multicenter, cross-sectional study of 3.934 patients aged ≥ 45 years with isolated PAD who were treated in primary care and specialized outpatient clinics during 2009. A diagnosis of PAD was reached for ankle brachial indices <0.9, a previous history of amputation or revascularization. In the overall population, the mean age was 67.6 years, 73.8% were males and 63% had MS (95% CI 61.5-64.3%). Patients with MS had a higher prevalence of cardiovascular risk factors and comorbidities, more severe PAD and higher prescription rate of evidence-based cardiovascular therapies. After adjusting for risk factors and comorbidity, there was a more frequent use of renin-angiotensin system blockers, beta-blockers, diuretics and statins among the patients with MS. A lower percentage of patients with MS achieved the therapeutic goals for blood pressure (22% vs. 41.5%, p<0.001). Similarly, a lower percentage of patients with diabetes achieved the glycated hemoglobin goals (44% vs. 53.1%, p<0.001), with no differences in LDL-cholesterol levels (29.8% vs. 39.1%, p=0.265). Patients with PAD have a high prevalence of MS. Patients with MS do not attain therapeutic goals as frequently as those without, despite taking more cardiovascular drugs.

    Moreo, Kathleen; Lattimer, Cheri; Lett, James E; Heggen-Peay, Cherilyn L; Simone, Laura

    Many continuing education (CE) resources are available to support case management professionals in developing competencies in transitions of care (TOC) that apply generally across disease areas. However, CE programs and tools are lacking for advanced TOC competencies in specific disease areas. This article describes 2 projects in which leading TOC, case management, and CE organizations collaborated to develop CE-accredited interdisciplinary pathways for promoting safe and effective TOC for patients with rare pulmonary diseases, including pulmonary arterial hypertension (PAH) and idiopathic pulmonary fibrosis (IPF). The interdisciplinary pathways apply to PAH and IPF case management practice and TOC across settings that include community-based primary care and specialty care, PAH or IPF centers of expertise, acute care and post-acute settings, long-term care, rehabilitation and skilled nursing facilities, and patients' homes. Both PAH and IPF are chronic, progressive respiratory diseases that are associated with severe morbidity and mortality, along with high health care costs. Because they are relatively rare diseases with nonspecific symptoms and many comorbidities, PAH and IPF are difficult to diagnose. Early diagnosis, referral to centers of expertise, and aggressive treatment initiation are essential for slowing disease progression and maintaining quality of life and function. Both the rarity and complexity of PAH and IPF pose unique challenges to ensuring effective and safe TOC. Expert consensus and evidence-based approaches to meeting these challenges, and thereby improving PAH and IPF patient outcomes, are presented in the 2 interdisciplinary TOC pathways that are described in this article. In coordinating care for patients with complex pulmonary diseases such as PAH and IPF, case managers across practice settings can play key roles in improving workflow processes and communication, transition planning, coordinating TOC with centers of expertise

    BACKGROUND Prions, the infectious agents responsible for transmissible spongiform encephalopathies, consist mainly of the misfolded prion protein (PrPSc). The unique mechanism of transmission and the appearance of a variant form of Creutzfeldt–Jakob disease, which has been linked to consumption of prion-contaminated cattle meat, have raised concerns about public health. Evidence suggests that variant Creutzfeldt–Jakob disease prions circulate in body fluids from people in whom the disease is silently incubating. METHODS To investigate whether PrPSc can be detected in the urine of patients with variant Creutzfeldt–Jakob disease, we used the protein misfolding cyclic amplification (PMCA) technique to amplify minute quantities of PrPSc, enabling highly sensitive detection of the protein. We analyzed urine samples from several patients with various transmissible spongiform encephalopathies (variant and sporadic Creutzfeldt–Jakob disease and genetic forms of prion disease), patients with other degenerative or nondegenerative neurologic disorders, and healthy persons. RESULTS PrPSc was detectable only in the urine of patients with variant Creutzfeldt–Jakob disease and had the typical electrophoretic profile associated with this disease. PrPSc was detected in 13 of 14 urine samples obtained from patients with variant Creutzfeldt–Jakob disease and in none of the 224 urine samples obtained from patients with other neurologic diseases and from healthy controls, resulting in an estimated sensitivity of 92.9% (95% confidence interval [CI], 66.1 to 99.8) and a specificity of 100.0% (95% CI, 98.4 to 100.0). The PrPSc concentration in urine calculated by means of quantitative PMCA was estimated at 1×10−16 g per milliliter, or 3×10−21 mol per milliliter, which extrapolates to approximately 40 to 100 oligomeric particles of PrPSc per milliliter of urine. CONCLUSIONS Urine samples obtained from patients with variant Creutzfeldt–Jakob disease contained minute

    To investigate if patients with periodontitis attending the Dental School in Huddinge, Sweden presented with more signs of systemic diseases, such as cardiovascular disease, diabetes mellitus and respiratory diseases, compared to healthy and gingivitis patients. In this retrospective study, dental charts were examined where the periodontal diagnoses of patients were known. A total of 325 patients with severe periodontitis and 149 patients without periodontitis, born 1928 to 1968, were identified. Diagnosis regarding the systemic diseases was self-reported. Odds ratios for cardiovascular diseases, diabetes mellitus and respiratory diseases were calculated with a logistic regression model that was adjusted for age, gender and smoking. It was observed that more cases of periodontitis were found in older individuals than the controls (61.7 vs 56.2 years; P < 0.001). A total of 44.3% of patients with severe periodontitis also suffered from cardiovascular diseases, 19.1% respiratory diseases and 21.2% from diabetes mellitus. Among the controls, 30.9% had cardiovascular disease, 23.5% suffered from respiratory diseases and 6.7% had diabetes mellitus. Across both groups, hypertension was the most frequent diagnosis. There was a significant association between periodontitis and cardiovascular disease (odds ratio [OR] = 1.79, confidence interval [CI] 1.12-2.86), but not between respiratory diseases and periodontitis (OR= 0.88, CI 0.53-1.47). The risk of diabetes mellitus was greater among those patients with periodontitis (OR= 2.95, CI 1.45- 6.01). This study found that patients with periodontitis presented with more systemic diseases, such as cardiovascular disease and diabetes mellitus than control patients. However, no association was found between periodontitis and respiratory diseases. At the present time, the reasons for the associations or lack of association are unknown.

    The purpose of this study was to assess the frequency and sonographic and laboratory characteristics of Graves disease with intrathyroid hypovascularity in Japanese patients and to compare these characteristics in patients with painless thyroiditis. A total of 194 consecutive patients with Graves disease and 21 patients with painless thyroiditis were enrolled. The patients underwent thyroid volume measurement, mean superior thyroid artery peak systolic velocity (PSV) measurement, power Doppler sonography, and proper blood testing to discriminate between Graves disease and painless thyroiditis. Based on the power Doppler sonographic findings, they were divided into 4 groups: from pattern 0 (most hypovascular thyroid) to pattern III (most hypervascular thyroid). Comparisons of multiple thyroid parameters were made among the groups. The prevalence of Graves disease with pattern 0 (n = 27) was 13.9% among the patients with Graves disease. The sonographic and laboratory data for patients with Graves disease and pattern 0 were compared to those of the 21 patients with painless thyroiditis, which typically shows intrathyroid hypovascularity. Free triiodothyronine and thyroxine levels and the superior thyroid artery PSV were significantly lower in patients with Graves disease and pattern 0 than those with patterns I, II, and III (P thyroid volume and thyrotropin receptor antibody level were significantly lower in patients with Graves disease and pattern 0 than those with pattern III. In the comparison between patients with Graves disease and pattern 0 and those with painless thyroiditis and pattern 0, apart from thyrotropin receptor antibody, only the superior thyroid artery PSV was different. Although the clinical features of patients with Graves disease and intrathyroid hypovascularity were similar to those patients with painless thyroiditis, the superior thyroid artery PSV showed a moderate ability to discriminate these patients. © 2014 by the American Institute of

    Achalasia is a rare disease of the esophagus that has an unknown etiology. Genetic, infectious, and autoimmune mechanisms have each been proposed. Autoimmune diseases often occur in association with one another, either within a single individual or in a family. There have been separate case reports of patients with both achalasia and one or more autoimmune diseases, but no study has yet determined the prevalence of autoimmune diseases in the achalasia population. This paper aims to compare the prevalence of autoimmune disease in patients with esophageal achalasia to the general population. We retrospectively reviewed the charts of 193 achalasia patients who received treatment at Toronto's University Health Network between January 2000 and May 2010 to identify other autoimmune diseases and a number of control conditions. We determined the general population prevalence of autoimmune diseases from published epidemiological studies. The achalasia sample was, on average, 10-15 years older and had slightly more men than the control populations. Compared to the general population, patients with achalasia were 5.4 times more likely to have type I diabetes mellitus (95% confidence interval [CI] 1.5-19), 8.5 times as likely to have hypothyroidism (95% CI 5.0-14), 37 times as likely to have Sjögren's syndrome (95% CI 1.9-205), 43 times as likely to have systemic lupus erythematosus (95% CI 12-154), and 259 times as likely to have uveitis (95% CI 13-1438). Overall, patients with achalasia were 3.6 times more likely to suffer from any autoimmune condition (95% CI 2.5-5.3). Our findings are consistent with the impression that achalasia's etiology has an autoimmune component. Further research is needed to more conclusively define achalasia as an autoimmune disease. © 2011 Copyright the Authors.

    Treatment recommendations for patients with upper abdominal Stage IIIA Hodgkin's (III1A) disease have varied widely. The current study reports on a combined institutional retrospective review of 85 patients with surgically staged III1A Hodgkin's disease. Twenty-two patients received combined modality therapy (CMT), 36 patients were treated initially with total nodal irradiation (TNI), and 27 with mantle and para-aortic radiotherapy (MPA). Patients treated with CMT had an actuarial 8-year freedom from relapse (FFR) of 96% as compared to a FFR of 51% in TNI treated patients (p = 0.002), and a FFR of 54% in MPA treated patients (p = 0.004). Of the 11 relapses in MPA treated patients, 7 had a component of their failure in the untreated pelvic or inguinal nodes. The patients treated with CMT had an 8-year actuarial survival of 100% as compared to 79% in TNI treated patients (p = 0.055) and 78% in patients treated with MPA (p = 0.025). Histology and the number of splenic nodules were the most important prognostic variables. Patients with MC/LD histology and greater than or equal to 5 splenic nodules have a high risk of relapse (10/13) when treated with radiation alone (TNI or MPA). We recommend CMT for this group of patients. Patients with NS/LP histology and 1-4 splenic nodules represent a favorable subset of Stage III1A patients. Only 4/21 patients have relapsed and all 21 patients are currently alive without disease regardless of treatment. We currently feel that patients with Stage III1A Hodgkin's disease with NS/LP histology and splenic disease limited to 1-4 nodules are good candidates for MPA as an alternative to TNI or CMT.

    Non-alcoholic fatty liver disease (NAFLD) encompasses a wide spectrum of liver disease that ranges from hepatic steatosis to non-alcoholic steatohepatitis. Obesity and diabetes mellitus are the prime risk factors for NAFLD. The aim of this study was to find out the prevalence of NAFLD among patients with type 2 diabetes mellitus and to detect the association of NAFLD with cardiovascular disease in them. Prospective observational study. The study was conducted on 300 patients with type 2 diabetes mellitus attending the outpatient department of a tertiary care teaching hospital. All patients underwent hepatic ultrasonography to look for hepatic steatosis. Among the 300 patients, 124 were divided into NAFLD and non-NAFLD groups based on the ultrasound findings. These patients were subjected to electrocardiogram, 2D echocardiogram, carotid intima media thickness (CIMT) measurement and ankle brachial pressure index measurement along with measurement of markers of oxidative stress. Hepatic steatosis was present in 61% of diabetic patients in this study. Cardiovascular disease was not found to be significantly associated in diabetic patients with NAFLD. However, cardiovascular risk factors like CIMT, high sensitivity c-reactive protein (hs-CRP) and malondialdehyde (MDA) were elevated in these patients. hs-CRP and MDA levels were found to be significantly associated with the severity of NAFLD. There is a high prevalence of NAFLD in type 2 diabetic patients. No correlation was detected between the presence of NAFLD and cardiovascular disease in them; although there was an association between cardiovascular risk factors and NAFLD. Copyright © 2018.

    Full Text Available Abstract Background The encephalopathy associated with autoimmune thyroid disease (EAATD is characterized by neurological/psychiatric symptoms, high levels of anti-thyroid antibodies, increased cerebrospinal fluid protein concentration, non-specific electroencephalogram abnormalities, and responsiveness to the corticosteroid treatment in patients with an autoimmune thyroid disease. Almost all EAATD patients are affected by Hashimoto's thyroiditis (HT, although fourteen EAATD patients with Graves' disease (GD have been also reported. Methods We have recorded and analyzed the clinical, biological, radiological, and electrophysiological findings and the data on the therapeutic management of all GD patients with EAATD reported so far as well as the clinical outcomes in those followed-up in the long term. Results Twelve of the fourteen patients with EAATD and GD were women. The majority of GD patients with EAATD presented with mild hyperthyroidism at EAATD onset or shortly before it. Active anti-thyroid autoimmunity was detected in all cases. Most of the patients dramatically responded to corticosteroids. The long term clinical outcome was benign but EAATD can relapse, especially at the time of corticosteroid dose tapering or withdrawal. GD and HT patients with EAATD present with a similar clinical, biological, radiological, and electrophysiological picture and require an unaffected EAATD management. Conclusions GD and HT equally represent the possible background condition for the development of EAATD, which should be considered in the differential diagnosis of all patients with encephalopathy of unknown origin and an autoimmune thyroid disease, regardless of the nature of the underlying autoimmune thyroid disease.

    Two treatment policies for the therapy of patients with Stage IIIA Hodgkin's disease are compared. From 1969-1976, 49 newly diagnosed and pathologically staged IIIA patients received total nodal irradiation (TNI) alone (no liver irradiation). Although actuarial survival was 80% at 5 years and 68% at 10 years, actuarial freedom from relapse was only 38% at 5 years. Accordingly, a new treatment policy was instituted in 1976. Patients with either CS IIIA disease, multiple splenic nodules, IIIA with a large mediastinal mass or III 2 , received combined modality therapy (combination chemotherapy and irradiation). All others received TNI. Thirty-six patients have been treated under the new program. The actuarial survival is 90% at 5 years and the relapse-free survival is 87%, suggesting the superiority of this approach. Complications from the treatments are discussed

    Cushing's syndrome is associated with an increased cardiovascular risk. Although a series of cardiovascular risk factors have been identified, sulfur amino acids (SAAs), recently indicated as independent cardiovascular risk factors, have been poorly investigated in patients with Cushing's syndrome. The aim of this cross-sectional controlled study was to evaluate serum and urinary levels and urinary excretion rate (ER) of SAAs in patients with Cushing's disease (CD) during the active disease and after long-term disease remission. Forty patients with CD (20 with active disease and 20 with cured disease for at least 5 yr) and 40 controls entered the study. Serum and urinary concentrations and urinary ER of SAAs, namely methionine, cystine, homocysteine, and taurine, were measured by means of cationic exchange HPLC. Serum folic acid and vitamin B12 levels were also evaluated in patients and controls and correlated to SAA levels. CD patients with active disease had higher serum and urinary concentrations of cystine and homocysteine, and lower serum and higher urinary concentrations and ER of taurine than cured patients and controls. Vitamin B12 levels were significantly decreased in patients with active disease compared with cured patients and controls, whereas folic acid levels were slightly decreased in patients than in controls. In patients with active CD, urinary cortisol concentrations were significantly and inversely correlated to serum taurine and directly correlated to taurine urinary ER, and fasting serum glucose levels were significantly correlated to taurine urinary ER. At the multiple regression analysis, urinary cortisol concentrations were the best predictors of taurine ER. CD is associated with hyperhomocysteinemia and hypotaurinemia. Glucocorticoid excess, acting directly or indirectly, seems to be the most responsible for this imbalance in SAA levels. The long-term disease remission is accompanied by normalization of SAA levels. Hyperhomocysteinemia and

    This study aimed to evaluate the diagnostic utilities of the automated connective tissues disease screening assay, CTD screen, in patients with systemic rheumatic diseases. A total of 1093 serum samples were assayed using CTD screen and indirect immunofluorescent (IIF) methods. Among them, 162 were diagnosed with systemic rheumatic disease, including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), and mixed connective tissue disease (MCT). The remaining 931 with non-systemic rheumatic disease were assigned to the control group. The median ratios of CTD screen tests were significantly higher in the systemic rheumatic disease group than in the control group. The positive likelihood ratios of the CTD screen were higher than those of IIF in patients with total rheumatic diseases (4.1 vs. 1.6), including SLE (24.3 vs. 10.7). The areas under the receiver operating characteristic curves (ROC-AUCs) of the CTD screen for discriminating total rheumatic diseases, RA, SLE, and MCT from controls were 0.68, 0.56, 0.92 and 0.80, respectively. The ROC-AUCs of the combinations with IIF were significantly higher in patients with total rheumatic diseases (0.72) and MCT (0.85) than in those of the CTD screen alone. Multivariate analysis indicated that both the CTD screen and IIF were independent variables for predicting systemic rheumatic disease. CTD screen alone and in combination with IIF were a valuable diagnostic tool for predicting systemic rheumatic diseases, particularly for SLE.

    A German study diagnosed 4% of young cryptogenic ischemic stroke patients with Fabry disease, an X-linked lysosomal storage disease caused by mutations in the alpha-galactosidase A (α-GAL-A) gene resulting in an accumulation of glycosphingolipids. A lower prevalence was found in other geographic regions. To determine the prevalence of Fabry disease in a Canadian population of young cryptogenic ischemic stroke patients. Patients with cryptogenic ischemic stroke at age 16-55 were retrospectively identified in our institutional stroke database and underwent a focused clinical evaluation. We sequenced the α-GAL-A gene and measured the levels of blood globotriaosylsphingosine in subjects with mutations of undetermined pathogenicity. Fabry disease was diagnosed in patients with pathogenic mutations or increased levels of blood globotriaosylsphingosine. Ninety-three of 100 study subjects had normal α-GAL-A gene polymorphisms. Seven had mutations of undetermined pathogenicity, including one with increased globotriaosylsphingosine (prevalence, 1%; 95% confidence interval, ischemic stroke presentation as the first clinical manifestation of Fabry disease. Both Fabry patients experienced recurrent ischemic stroke. Fabry disease accounts for a small proportion of young Canadians with cryptogenic ischemic stroke.

    Phenylketonuria (PKU) still poses a therapeutic challenge for patients and medical professionals. The aim of the study was to assess both patients' and their parents' acceptance of the disease. The study included 218 PKU patients and 178 parents of PKU children who were enrolled in the study on the basis of questionnaire data. Regarding attitude towards the disease, our study demonstrated that 63 (28.9 %) PKU patients did not accept the disease. Patients who found accepting the disease difficult, more frequently perceived themselves as inferior/different in comparison with their peers. In total, 36 % of patients did not want their friends to be aware of their condition, while only 18 % of parents believed that their children's peers should not know about their disease. In total, 42 % of parents wanted to talk to other parents of PKU children and only 13 % to a doctor. Only 20 % of patients saw the need to discuss their condition with a doctor. In total, 8 % of children, regardless of age, and 14 % of parents preferred to talk to a psychologist. Our data demonstrated that disease acceptance played an essential role in patients' social integration. The study also indicated the need to overcome communication barriers between patients and their healthy peers and for patients to find the courage to be open about the disease. The importance of support groups for PKU families and the significance of strict cooperation between patients and their families with PKU treatment teams were also revealed.

    Looking in literature reveals that aging is accompanied by olfactory dysfunction and hyposmia/anosmia is a common manifestation in some neurodegenerative disorders. Olfactory dysfunction is regarded as non-motor manifestations of Parkinson disease (PD). The main goal of this study was to examine the extent of olfactory dysfunction in Persian PD patients. We used seven types of odors including rosewater, mint, lemon, garlic which were produced by Barij Essence Company in Iran. Additionally, coffee and vinegar were used. Subjects had to distinguish and name between seven previously named odors, stimuli were administered to each nostril separately. Totally, 92 patients and 40 controls were recruited. The mean (standard deviation) (SD) age patients was 64.88 (11.30) versus 61.05 (7.93) in controls. The male: female ratio in patients was 50:42 versus 22:18 in control group. Also, mean UPDRS score (SD) in patients was 24.42 (5.08) and the disease duration (SD) was 3.72 (3.53). Regarding the number of truly detected odors, there were a significant higher number of correct identified odors in control group in comparison with the PD patients. Furthermore, there was a significant negative correlation between number of correct diagnosed smells and UPDRS (Pearson Correlation= -0.27, P = 0.009); conversely, no significant correlation between the duration of Parkinson disease and number of correct diagnosed smells (P > 0.05). Smelling dysfunction is a major problem in Persian PD patients and it requires vigilant investigation for the cause of olfactory dysfunction exclusively in elder group and looking for possible PD disease.

    Cardiovascular disease among hemodialysis (HD) patients is linked to poor outcomes. The Acute Dialysis Quality Initiative Workgroup proposed echocardiographic (ECHO) criteria for structural heart disease (SHD) in dialysis patients. The association of SHD with important patient outcomes is not well defined. This study sought to determine prevalence of ECHO-determined SHD and its association with survival among incident HD patients. We analyzed patients who began chronic HD from 2001 to 2013 who underwent ECHO ≤1 month prior to or ≤3 months following initiation of HD (n = 654). Mean patient age was 66 ± 16 years, and 60% of patients were male. ECHO findings that met 1 or more and ≥3 of the new criteria were discovered in 87% and 54% of patients, respectively. Over a median of 2.4 years, 415 patients died: 108 (26%) died within 6 months. Five-year mortality was 62%. Age- and sex-adjusted structural heart disease variables associated with death were left ventricular ejection fraction (LVEF) ≤45% (hazard ratio [HR]: 1.48; confidence interval [CI]: 1.20 to 1.83) and right ventricular (RV) systolic dysfunction (HR: 1.68; CI: 1.35 to 2.07). An additive of higher death risk included LVEF ≤45% and RV systolic dysfunction rather than neither (HR: 2.04; CI: 1.57 to 2.67; p = 0.53 for test for interaction). Following adjustment for age, sex, race, diabetic kidney disease, and dialysis access, RV dysfunction was independently associated with death (HR: 1.66; CI 1.34 to 2.06; p < 0.001). SHD was common in our HD study population, and RV systolic dysfunction independently predicted mortality. Copyright © 2016 American College of Cardiology Foundation. Published by Elsevier Inc.

    Impulse control disorders occur frequently in patients with Parkinson's disease. However, the frequencies have been investigated mainly in patients from secondary or tertiary care centers, and thus, the prevalence rates in general community are not known. Our objective was to study the prevalence rates of impulse control disorders and related factors in a large, non-selected sample of Parkinson's disease patients. We conducted a cross-sectional survey among Parkinson's disease patients from Finnish Parkinson Association [n = 575; 365 men, 240 women, median age 64 (range 43-90) years]. Problem and pathological gambling were estimated with the South Oaks Gambling Screen, risk for impulse control disorders with the validated Questionnaire for Impulsive-Compulsive Disorders in Parkinson's Disease, and depression with the Beck Depression Inventory. The frequency of pathological gambling was 7.0%. The overall frequency of a positive screen for an impulse control disorder was 34.8%, and 12.5% of the patients screened positive for multiple disorders. Depressive symptoms were statistically the most important factor in explaining variance in impulse control disorder risk, even more than sex, age, age of disease onset, alcohol use, or medication. The high proportion of patients screened positive for impulse control disorders in a non-selected sample emphasize the importance of routine screening of these disorders in Parkinson's disease. Pathological gambling prevalence in Parkinson's disease is seven times higher than in the general population in Finland. The results underline the importance of depression in impulse control disorders associated with Parkinson's disease. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Liver disease is associated with both hemorrhagic and thrombotic processes, including an elevated risk of intracranial hemorrhage. We sought to assess the relationship between liver disease and outcomes after stroke, as measured by discharge disposition. Using administrative claims data, we identified a cohort of patients hospitalized with stroke in California, Florida, and New York from 2005 to 2013. The predictor variable was liver disease. All diagnoses were defined using validated diagnosis codes. Ordinal logistic regression was used to analyze the association between liver disease and worsening discharge disposition: home, nursing/rehabilitation facility, or death. Secondarily, multiple logistic regression was used to analyze the association between liver disease and in-hospital mortality. Models were adjusted for demographics, vascular risk factors, and comorbidities. We identified 121 428 patients with intracerebral hemorrhage and 703 918 with ischemic stroke. Liver disease was documented in 13 584 patients (1.7%). Liver disease was associated with worse discharge disposition after both intracerebral hemorrhage (global odds ratio, 1.28; 95% confidence interval, 1.19-1.38) and ischemic stroke (odds ratio, 1.23; 95% confidence interval, 1.17-1.29). Similarly, liver disease was associated with in-hospital death after both intracerebral hemorrhage (odds ratio, 1.33; 95% confidence interval, 1.23-1.44) and ischemic stroke (odds ratio, 1.60; 95% confidence interval, 1.51-1.71). Liver disease was associated with worse hospital discharge disposition and in-hospital mortality after stroke, suggesting worse functional outcomes. © 2016 American Heart Association, Inc.

    Disease of systemic lupus erythematosus (SLE) and periodontal disease (PD) shares the common multiple characteristics. The aims of the present study were to evaluate the prevalence and severity of periodontal disease in Chinese SLE patients and to determine the association between SLE features and periodontal parameters. A cross-sectional study of 108 SLE patients together with 108 age- and sex-matched healthy controls was made. Periodontal status was conducted by two dentists independently. Sociodemographic characteristics, lifestyle factors, medication use, and clinical parameters were also assessed. The periodontal status was significantly worse in SLE patients compared to controls. In univariate logistic regression, SLE had a significant 2.78-fold [95% confidence interval (CI) 1.60-4.82] increase in odds of periodontitis compared to healthy controls. Adjusted for potential risk factors, patients with SLE had 13.98-fold (95% CI 5.10-38.33) increased odds against controls. In multiple linear regression model, the independent variable negatively and significantly associated with gingival index was education (P = 0.005); conversely, disease activity (P periodontitis of SLE in multivariate logistic regression (OR 1.348; 95% CI: 1.183-1.536, P < 0.001). Chinese SLE patients were likely to suffer from higher odds of PD. These findings confirmed the importance of early interventions in combination with medical therapy. It is necessary for a close collaboration between dentists and clinicians when treating those patients.

    Morgellons disease is an emerging skin disease characterized by formation of dermal filaments associated with multisystemic symptoms and tick-borne illness. Some clinicians hypothesize that these often colorful dermal filaments are textile fibers, either self-implanted by patients or accidentally adhering to lesions, and conclude that patients with this disease have delusions of infestation. We present histological observations and electron microscopic imaging from representative Morgellons disease samples revealing that dermal filaments in these cases are keratin and collagen in composition and result from proliferation and activation of keratinocytes and fibroblasts in the epidermis. Spirochetes were detected in the dermatological specimens from our study patients, providing evidence that Morgellons disease is associated with an infectious process.

    Full Text Available Chagas' disease causes degeneration and reduction of the number of intrinsic neurons of the esophageal myenteric plexus, with consequent absent or partial lower esophageal sphincter relaxation and loss of peristalsis in the esophageal body. The impairment of esophageal motility is seen mainly in the distal smooth muscle region. There is no study about esophageal striated muscle contractions in the disease. In 81 patients with heartburn (44 with esophagitis taken as controls, 51 patients with Chagas' disease (21 with esophageal dilatation and 18 patients with idiopathic achalasia (11 with esophageal dilatation we studied the amplitude, duration and area under the curve of esophageal proximal contractions. Using the manometric method and a continuous perfusion system we measured the esophageal striated muscle contractions 2 to 3 cm below the upper esophageal sphincter after swallows of a 5-ml bolus of water. There was no significant difference in striated muscle contractions between patients with heartburn and esophagitis and patients with heartburn without esophagitis. There was also no significant difference between patients with heartburn younger or older than 50 years or between men and women or in esophageal striated muscle contractions between patients with heartburn and Chagas' disease. The esophageal proximal amplitude of contractions was lower in patients with idiopathic achalasia than in patients with heartburn. In patients with Chagas' disease there was no significant difference between patients with esophageal dilatation and patients with normal esophageal diameter. Esophageal striated muscle contractions in patients with Chagas' disease have the same amplitude and duration as seen in patients with heartburn. Patients with idiopathic achalasia have a lower amplitude of contraction than patients with heartburn.

    BACKGROUND: Excessive alcohol use has been implicated as a risk factor in the development of psoriasis, particularly in men. Despite this, little is known of the incidence or prevalence of psoriasis in patients who misuse alcohol. OBJECTIVE: To assess the prevalence of psoriasis in patients with alcoholic liver disease. METHODS: In total, 100 patients with proven alcoholic liver disease were surveyed for a history of psoriasis and a full skin examination was performed if relevant. RESULTS: Of the 100 patients, 15 reported a history of psoriasis and another 8 had evidence of current activity, suggesting a prevalence (past or present) of 15% in this group of patients. CONCLUSION: It would appear that the prevalence of psoriasis in patients who misuse alcohol is much higher than the 1-3% variously quoted in the general population.

    Hypovitaminosis D as a result of malnutrition or sunlight deprivation, increased bone resorption, low bone mineral density (BMD), or an increased risk of falls may contribute to an increased risk of hip fractures in patients with neurological diseases, including Alzheimer's disease, Parkinson's disease, and stroke. The purpose of this study was to clarify the efficacy of sunlight exposure for reducing the risk of hip fractures in patients with such neurological diseases. The English literature was searched using PubMed, and randomized controlled trials evaluating the efficacy of sunlight exposure for reducing the risk of hip fractures in patients with Alzheimer's disease, Parkinson's disease, and stroke were identified. The relative risk and the 95% confidence interval were calculated for individual randomized controlled trials, and a pooled data analysis (meta-analysis) was performed. Three randomized controlled trials were identified. Sunlight exposure improved hypovitaminosis D and increased the BMD. The relative risk (95% confidence interval) of hip fractures was 0.22 (0.05, 1.01) for Alzheimer's disease, 0.27 (0.08, 0.96) for Parkinson's disease, and 0.17 (0.02, 1.36) for stroke. The relative risk (95% confidence interval) calculated for the pooled data analysis was 0.23 (0.10, 0.56) (P = 0.0012), suggesting a significant risk reduction rate of 77%. The present meta-analysis added additional evidence indicating the efficacy of sunlight exposure for reducing the risk of hip fractures in patients with Alzheimer's disease, Parkinson's disease, and stroke. © 2011 John Wiley & Sons A/S.

    Including target populations in the design and implementation of research trials has been one response to the growing health disparities endemic to our health care system, as well as an aid to study generalizability. One type of community-based participatory research is "Patient Centered-Research", in which patient perspectives on the germane research questions and methodologies are incorporated into the study. The Patient-Centered Outcomes Research Institute (PCORI) has mandated that meaningful patient and stakeholder engagement be incorporated into all applications. As of March 2015, PCORI funded seven clinically-focused studies of patients with kidney disease. The goal of this paper is to synthesize the experiences of these studies to gain an understanding of how meaningful patient and stakeholder engagement can occur in clinical research of kidney diseases, and what the key barriers are to its implementation. Our collective experience suggests that successful implementation of a patient- and stakeholder-engaged research paradigm involves: (1) defining the roles and process for the incorporation of input; (2) identifying the particular patients and other stakeholders; (3) engaging patients and other stakeholders so they appreciate the value of their own participation and have personal investment in the research process; and (4) overcoming barriers and challenges that arise and threaten the productivity of the collaboration. It is our hope that the experiences of these studies will further interest and capacity for incorporating patient and stakeholder perspectives in research of kidney diseases.

    Full Text Available Arteriosclerosis is the basis of all cardiovascular diseases. Numerous risk factors lead to the rise of malignant and cardiovascular diseases. Those are: elevated artery blood pressure, raised plasma cholesterol and triglycerides, low level of HDL-cholesterol, smoking, diabetes mellitus, diet, lack of physical exercises, heredity, stress, gender.The aim of the study was to compare the lipid status of patients with cardiovascular disease or malignancy.The database of the biochemical laboratory and oncology counseling unit of the "Ostrog Clinic" was used. The method of random sample was used and patients (n=29 of both genders were selected, who were at the age of 40 to 47, with cardiovascular diseases, and had significant occlusive coronary disease, which required operation or surgical revascularization procedure. The patients were classified in two groups: G1 (n=14 with statin therapy and G2 (n=15 without statin therapy. Both groups were statistically compared with a group of female patients (n=30 with breast cancer, who were between 37 and 69 years of age. Control group comprised 25 healthy subjects. Standard statistical methods were used for processing the lipid status parameters, namely: the arithmetic mean, standard deviation SDn and SDn-1, correlation coefficient, post hock test and a single factor analysis of variance.The results obtained have pointed to the existence of a marked hyperlipoproteinemia type 4 in the group of cardiovascular patients who did not use statin (G2. In G2, higher levels of cholesterol, LDL-cholesterol and plasma triglycerides in comparison with the control and G1, while the value of HDL-cholesterol was within the range of referent values. The obvious suppressing effect of statin on cholesterol and LDL-cholesterol was observed in G1. Group G3 had, in comparison with the control and cardiovascular patients, significantly lower levels of cholesterol and triglycerides in plasma, as well as lower index of atherosclerosis

    Full Text Available OBJECTIVES AND BACKGROUND Patients with chronic kidney disease (CKD represent a special category of risk. As part of the renal and cardiovascular continuum from risk factors to terminal phase diseases, they develop clinical syndromes with potentially severe prognosis. The aim of this study was to assess the echocardiographic parameters and different responses to treatment in dialysed patients. MATERIALS AND METHODS We examined a number of 1200 dialysed patients (DP with a mean follow-up of 3 years RESULTS Patients on dialysis have severe cardiac risk, an intense atherogenic hyperlipidemic profile, phosphocalcic metabolic alterations and thus a higher rate of atheroma development and occurrence of degenerative valve diseases. These patients are knon to have higher cardiovascular mortality and morbidity and are potential candidates for aggressive reduction of risk factors. Unlike hypertrophy, angiogenesis develops gradually, therefore, oxygen diffusion is prolonged at least 25%. Even mild renal failure is associated with a decreased coronary flow reserve in patients with non-obstructive CAD. This reserve decreases once more in hypertensive DP. Microvascular remodeling determins a reduction in the number of capilary vessels. As a result, DPs are exposed to higher risk for the occurrence of ischemic events and cardiac arrhythmia. The administration of ACE inhibitors and betablockers at the highest tolerated dose decreased cardiovascular morbidity and mortality and improved life quality. Moreover, small doses of these drugs proved to be effective even in patients where hemodialysis alone was enough to control blood pressure. CONCLUSIONS 1. Efficient hemodialysis procedure represents one step in order to control high blood pressure; however, LV hypertrophy in hypertensive dialysed patients (DPs has some particularities 2. The use of ACE inhibitors decreased hypertrophy and improved diastolic filling 3. Blood pressure and electrolyte control

    To explore whether the cognitive impairment is correlated with freezing of gait (FOG) in patients with Parkinson disease (PD). A total of 186 patients with Parkinson disease (104 patients with FOG and 82 patients with no clinical history of freezing behavior) and 125 healthy individuals were selected for this study. Neuropsychological assessments, including the scales for outcomes in Parkinson disease cognition, unified Parkinson's disease rating scale, and Hamilton depression/anxiety rating scale etc., were applied to evaluate the patients'cognitive functioning. We found that the scores of Unified Parkinson's Disease Rating Scale (UPDRS) were significantly higher among PD patients with FOG, compared with non-FOG group. We also showed that Mini-Mental State Examination score (MMSE) was lower among subjects with FOG than in patients without FOG. Patients with FOG displayed lower Scales for OUTCOMES: in Parkinson's Disease Cognition (SCOPA-COG) score than non-FOG patients. In addition, significant higher Hamilton Anxiety Rating Scale (HAMD) scores were found in patients with FOG than patients without FOG. Moreover, disease duration, stage of the disease, the severity of motor symptom, increased depressive and anxiety complaints measured by FOG questionnaire were significantly associated with severity of FOG. Meanwhile, we also found that the score of Freezing of Gait Questionnaire (FOGQ) score was negatively correlated with MMSE. Our results demonstrated that FOG is related to impaired cognitive functions in PD patients with FOG. The understanding of impaired cognitive functions in PD patients with FOG can provide evidences for possible therapeutic interventions. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Abstract. We studied cytokine profile in blood and exhaled breath condensate (EBC in patients with chronic obstructive pulmonary disease (COPD being in remission state. It is shown that pro- and anti-inflammatory cytokine contents depended on the disease severity, both in whole blood and EBC of the COPD patients. We have revealed an increase in TNFα, s-TNFα RI, TGF-β1 and bFGF in EBC of patients with COPD manifestations, thus being indicative for progression of metabolic changes in lung tissue, and advanced stage of respiratory functional disturbances. Cytokine profile abnormalities in COPD patients resulting, in part, from systemic and local disorders of cellular immunity, represent a major pathogenetic mechanism determining the disease progression.

    Although the Unified Parkinson's Disease Rating Scale (UPDRS) is the "gold-standard" tool in assessing the severity of symptoms in patients with Parkinson's disease (PD), not all activity-related disease symptoms can be accurately captured by the well-established clinical rating scale. Using an alternative approach, this study examined the level of physical activity measured by actigraphy over time and whether change in physical activity was associated with disease severity assessed by UPDRS. We used a longitudinal design in which physical activity and disease severity were assessed repeatedly during a 4-month interval, over a 3-year observational period, in a sample of 61 patients with idiopathic PD and a control group of 32 neurologically intact individuals. Physical activity data during awake-time were analyzed using the power-law exponent (PLE) method. Correlational relationships between changes in maxima values of PLE and scores of total UPDRS, UPDRS-part II (Activities of Daily Living), and UPDRS-part III (Motor Examination) in patients with PD were examined. Results show an increase in maxima values of PLE and the UPDRS total score in PD patients and that there is a positive association between changes in maxima values and total UPDRS score (r=0.746, p=0.032), UPDRS-part II score (r=0.687, p=0.027), and UPDRS-part III score (r=0.893, p=0.018). There was no significant change in the level of physical activity over time for the controls. Findings from this study indicate that change in physical activity, as captured by actigraphy, is associated with increased severity in patients' clinical symptoms of PD over time. Thus, these data suggest that, when used in conjunction with the conventional UPDRS measure, an actigraphic measure of physical activity may provide clinicians an adjunct measurement approach to monitor patients' activity-based disease progression or responses to treatment in outpatient clinic settings.

    Full Text Available Hirschsprung’s disease is a congenital motility disorder that is easily overlooked as a cause of chronic refractory constipation in adults. We present a case of Hirschsprung’s disease in a patient 70 years of age with a history of long-standing constipation, chronic use of laxatives, and recurrent episodes of colonic obstruction. Presumptive preoperative diagnosis was chronic ischemic sigmoid stenosis or intermittent sigmoid volvulus before Hirschsprung’s disease was suspected based on intraoperative colonoscopy and surgical findings. The diagnosis was confirmed by the absence of intrinsic ganglion cells on histopathologic examination of the surgical specimen and the absence of the rectoanal inhibitory reflex on postoperative manometry. A conservative surgical approach that limited the resection to the grossly diseased rectum successfully restored normal defecation despite the anastomosis being performed on the distal aganglionic rectum. This approach, which avoids extensive rectal dissection, may be suitable for older or frail patients. Heightened awareness of Hirschsprung’s disease is necessary to ensure its prompt recognition in the elderly.

    Individuals with special needs are at more risk of dental disease, including periodontal diseases, and have a greater prevalence and incidence of periodontal diseases than the rest of the population. Genetic or medical conditions, and/or the use of prescription medication or recreational substances, may further increase the risk for susceptibility to periodontal disease. The success of preventing or controlling periodontal diseases amongst this group of patients has not been established. Even those individuals who access regular and comprehensive dental care appear to develop periodontal diseases as they age, and this development occurs at a rate comparable to the natural history of the disease. The reasons behind the lack of success of interventions in reducing the incidence of periodontal diseases are complex and part of the lack of success may relate to the professional challenges in treating individuals with special needs. © 2017 John Wiley & Sons A/S.

  2. Patients' substantialization of disease, the hybrid symptom and metaphysical care.

    2015-06-01

    In the context of current scholarship concerned with facilitating integration between the biomedical and the patient-centred models of care, the article suggests that disease brings about an ontological disruption in patients, which is not directly addressed in either model, and may interfere with treatment and therapy outcomes if not met with a type of care termed here as 'metaphysical'. The receipt of diagnosis and medical care can give patients the sense that they are ontologically diminished, or less of a human, and along with physicians' approaches to and discourses about disease, may prompt them to seek ontological restoration or security in the same way as psychologically traumatized patients sometimes do: by treating the disease and/or the experience of harm associated with it as a thing that exists per se. I call this 'substantialization' of disease (or harm) and draw on Augustine's theory of non-substantial deficiencies (physiological and moral) and on Plato's and Plotinus's different takes on such defects in order to discuss what substantialization can do for patients. Based on literature that examines patients' ways of talking about and living with their disease, I speculate that substantialization can generate a 'hybrid symptom', consisting in patterns of exercising agency which may predispose to non-adherence. Ways in which physicians could provide metaphysical care are proposed, along with an understanding of chronic patients as hybrid ontological and agentic units, which draws on theories of enactive cognition. I opine that metaphysical care may facilitate integration between the depersonalized and personalized models of care. © 2014 John Wiley & Sons, Ltd.

    2012-08-01

    Full Text Available Abstract Background Uveitis is an autoimmune disease of the eye that refers to any of a number of intraocular inflammatory conditions. Because it is a rare disease, uveitis is often overlooked, and the possible associations between uveitis and extra-ocular disease manifestations are not well known. The aim of this study was to characterize uveitis in a large sample of patients and to evaluate the relationship between uveitis and systemic diseases. Methods The present study is a cross-sectional study of a cohort of patients with uveitis. Records from consecutive uveitis patients who were seen by the Uveitis Service in the Department of Ophthalmology at the Medical University of Vienna between 1995 and 2009 were selected from the clinical databases. The cases were classified according to the Standardization of Uveitis Nomenclature Study Group criteria for Uveitis. Results Data were available for 2619 patients, of whom 59.9% suffered from anterior, 14.8% from intermediate, 18.3% from posterior and 7.0% from panuveitis. 37.2% of all cases showed an association between uveitis and extra-organ diseases; diseases with primarily arthritic manifestations were seen in 10.1% of all cases, non-infectious systemic diseases (i.e., Behçet´s disease, sarcoidosis or multiple sclerosis in 8.4% and infectious uveitis in 18.7%. 49.4% of subjects suffering from anterior uveitis tested positively for the HLA-B27 antigen. In posterior uveitis cases 29% were caused by ocular toxoplasmosis and 17.7% by multifocal choroiditis. Conclusion Ophthalmologists, rheumatologists, infectiologists, neurologists and general practitioners should be familiar with the differential diagnosis of uveitis. A better interdisciplinary approach could help in tailoring of the work-up, earlier diagnosis of co-existing diseases and management of uveitis patients.

    Patients with celiac disease are at increased risk for infections such as tuberculosis, influenza, and pneumococcal pneumonia. However, little is known about the incidence of Clostridium difficile infection (CDI) in patients with celiac disease. We identified patients with celiac disease based on intestinal biopsies submitted to all pathology departments in Sweden over a 39-year period (from July 1969 through February 2008). We compared risk of CDI (based on stratified Cox proportional hazards models) among patients with celiac disease vs. without celiac disease (controls) matched by age, sex, and calendar period. We identified 28,339 patients with celiac disease and 141,588 controls; neither group had a history of CDI. The incidence of CDI was 56/100,000 person-years among patients with celiac disease and 26/100,000 person-years among controls, yielding an overall hazard ratio (HR) of 2.01 (95% confidence interval (CI), 1.64-2.47; Pceliac disease (HR, 5.20; 95% CI, 2.81-9.62; Pceliac disease and controls. In a large population-based cohort study, patients with celiac disease had significantly higher incidence of CDI than controls. This finding is consistent with prior findings of higher rates of other infections in patients with celiac disease, and suggests the possibility of altered gut immunity and/or microbial composition in patients with celiac disease.

    The spectrum of serological markers associated with inflammatory bowel disease (IBD) is rapidly growing. Due to frequently delayed or missed diagnoses, the application of non-invasive diagnostic tests for IBD, as well as differentiation between ulcerative colitis (UC) and Crohn’s disease (CD), would be useful in the pediatric population. In addition, the combination of pancreatic autoantibodies and antibodies against Saccharomyces cerevisiae antibodies/perinuclear cytoplasmic antibody (pANCA) improved the sensitivity of serological markers in pediatric patients with CD and UC. Some studies suggested that age-associated differences in the patterns of antibodies may be present, particularly in the youngest children. In CD, most patients develop stricturing or perforating complications, and a significant number of patients undergo surgery during the disease course. Based on recent knowledge, serum antibodies are qualitatively and quantitatively associated with complicated CD behavior and CD-related surgery. Pediatric UC is characterized by extensive colitis and a high rate of colectomy. In patients with UC, high levels of anti-CBir1 and pANCA are associated with the development of pouchitis after ileal pouch-anal anastomosis. Thus, serologic markers for IBD can be applied to stratify IBD patients into more homogeneous subgroups with respect to disease progression. In conclusion, identification of patients at an increased risk of rapid disease progression is of great interest, as the application of early and more aggressive pharmaceutical intervention could have the potential to alter the natural history of IBD, and reduce complications and hospitalizations.

    Objective: To evaluate changes in nutritional status of hospitalized patients with different diseases by subjective global assessment (SGA) and nutritional risk screening (NRS-2002). Methods: A prospective and parallel research done by multi-center collaboration from 34 hospitals in China from June to September 2014. Hospitalized patients with the following diseases were investigated: malignant tumor (2 487 cases), benign disease of the digestive system (1 358 cases), benign disease of the nervous system (1 043 cases), benign bone disease (451 cases), benign disease of the respiratory system(395 cases), cardiovascular disease (227 cases), benign thyroid and breast disease (179 cases), and endocrine disease (149 cases). Patients above the age of 18 and hospitalization time between 7-30 days were included. Physical indexes were measured, the NRS-2002 and SGA scores were recorded, the nutritional support were recorded during hospitalization and 24 hours after discharge from hospital. Measurement data between groups were analyzed using t test or Wilcoxon rank sum test, enumeration data and ranked data between groups were analyzed using chi-square test or Fisher exact test. Results: There were 6 638 cases of hospitalized patients, 3 861 cases were males and 2 777 were females, the male/female ratio was 1.4∶1.0; the median age was 60 years; the median height was 1.66 m; the median weight was 62 kg; the median body mass index (BMI)was 22.89 kg/m(2). At discharge, compared with that of admission, the body weight, BMI, grip strength, upper arm and calf circumferences of patients with malignant tumor were significantly decreased ( t =20.15-259.67, all P nutritional risk incidence rate (from NRS-2002) of patients with malignant tumor was significantly higher(χ(2)=21.275, P =0.000); moderate malnutrition (from SGA) incidence rate was significantly higher(χ(2)=62.318, P =0.000; χ(2)=11.312, P nutritional deficiency(except those with digestive benign diseases )received

    Coffee is one of the most commonly consumed beverages in the world. Consequently, it is important to consider the impact of coffee on health and disease. A daily intake of at least three cups of coffee is likely to have beneficial health effects, especially in patients at risk of liver diseases. Coffee has been associated with decreased liver inflammation, prevention of cirrhosis, reduced steatosis and lower incidence of hepatocellular carcinoma. It is not yet possible to make clear recommendations, but coffee can likely be included as part of a healthy diet for patients with liver diseases.

    2016-01-01

    INTRODUCTION: Patients with psoriasis have an increased incidence and prevalence of cardiovascular (CV) risk factors, and CV undertreatment in these patients is a well-established problem. The link between psoriasis and CV disease is present on a pathogenic level, as well as due to modifiable...... lifestyle factors such as smoking and alcohol abuse. AREAS COVERED: In this manuscript we describe the evidence associating psoriasis with CV disease, as well as the pharmacological and non-pharmacological treatment of CV risk factors including the CV effects of anti-psoriatic therapy and vice versa.

    A total of 42 symptomatic patients with coronary artery disease involving two or three vessels were studied using exercise thallium-201 myocardial scintigraphy. Qualitative analysis of the images predicted multivessel disease in 75% of the patients with two-vessel disease and in 82% of the patients with three-vessel disease. Quantitative analysis of the size of the perfusion defect indicated that approximately 40% of the left ventricular perimeter showed abnormal perfusion pattern during stress in these patients, and there was no significant difference in the size of the defect in patients with two-vessel disease or three-vessel disease (41 +/- 17% vs 42 +/- 14%, respectively, mean +/- SD). The exercise heart rate, exercise ECG response, and severity of narrowing did not correlate with the size of the perfusion defect. Patients with anterior infarction had larger defects in the distribution of the left anterior descending artery than those without infarction. Collaterals offered partial protection during exercise only when they were not jeopardized. This study confirms the value of qualitative analysis of exercise thallium-201 imaging in predicting multivessel disease, and describes a simple method of assessing the extent of perfusion abnormalities during stress in patients with multivessel disease. The results may be important in patient management and prognosis

    The main purpose of this article is to examine whether cognitive plasticity increases after cognitive training in Alzheimer's disease patients. Twenty six patients participated in this study, all of them diagnosed with mild Alzheimer's disease, 17 of them received a cognitive training program during 6 months, and the other 9 were assigned to the control group. Participants were assigned to experimental or control conditions for clinical reasons. In order to assess cognitive plasticity, all patients were assessed before and after treatment with three subtests from the "Bateria de Evaluación de Potencial de Aprendizaje en Demencias" [Assessment Battery of Learning Potential in Dementia] (BEPAD). After treatment, Alzheimer's disease patients improved their performance in all the tasks assessing cognitive plasticity: viso-spatial memory, audio-verbal memory and verbal fluency. However, the cognitive plasticity scores of the patients in the control group decreased. In conclusion, this study showed that cognitive stimulation programs can improve cognitive functioning in mildly demented patients, and patients who do not receive any cognitive interventions may reduce their cognitive functioning.

    The relevance of investigating carbohydrate metabolism (CM) in patients with acromegaly and Itsenko-Cushing disease is attributable to frequent glucose metabolic disturbances, on the one hand, and to difficulties in choosing sugar-lowering therapy in these categories of patients, on the other. The efficiency of hyperglycemia treatment in these patients may be reduced due to problems in achieving remission/cure of the underlying disease and to specific therapy favoring hyperglycemia. The top-priority tasks are to search for ways of reducing the frequency of CM abnormalities in patients with neuroendocrine diseases and to elaborate sugar-lowering therapy regimens. There is a growing interest in studies of the role of the incretin system in the pathogenesis of secondary hyperglycemias associated with neuroendocrine diseases. Nevertheless, few works have been published on this subject matter because of its novelty. There is a need for a further closer study of the specific features of incretin system function and the pharmacodynamics of incretin mimetics that are potential candidates as first-line drugs to treat secondary hyperglycemias. This paper attempts to summarize the available data obtained from studies into CM in neuroendocrine diseases.

    The purpose of our study is to investigate the delay in diagnosis of patients with biopsy-proven celiac disease in those who present with gastrointestinal complaints vs nongastrointestinal complaints at our tertiary care center. Celiac disease is an autoimmune disorder that affects approximately 1% of the population worldwide. Celiac disease can have variable clinical presentations; it can be characterized by predominately gastrointestinal symptoms, or it may present without any gastrointestinal symptoms. We retrospectively reviewed the charts of 687 adult patients who carried the diagnosis of celiac disease. Patients included had biopsy-proven celiac disease and were categorized based on presence or absence of gastrointestinal symptoms prior to their diagnosis. There were 101 patients with biopsy-proven celiac disease that met inclusion criteria. Fifty-two patients presented with gastrointestinal symptoms and 49 had nongastrointestinal complaints. Results from Mann-Whitney statistical analysis showed a median delay in diagnosis of 2.3 months for the gastrointestinal symptoms group and 42 months for the nongastrointestinal group (P symptoms had abnormal thyroid-stimulating hormone, as opposed to 15.5% in the gastrointestinal symptom group (P = .004). Of patients with nongastrointestinal symptoms, 69.4% had anemia, compared with 11.5% of the gastrointestinal symptom group (P symptom group, 68%, were noted to have abnormal bone density scans, compared with 41% in the gastrointestinal symptom group. No sex differences were noted on chi-squared analysis between the 2 groups (P = .997). Although there is growing awareness of celiac disease, the delay in diagnosis for patients without gastrointestinal symptoms remains prolonged, with an average delay of 3.5 years.

    Full Text Available Introduction. Pompe disease (PD, a lysosomal storage disease as well as a neuromuscular disorder, is a rare disease marked by progressive muscle weakness. Enzyme replacement therapy (ERT in recent years allowed longer survival but brought new problems to the treatment of PD with increasing affection of the musculoskeletal system, particularly with a significantly higher prevalence of scoliosis. The present paper deals with the orthopedic problems in patients with PD and is the first to describe surgical treatment of scoliosis in PD patients. Patients and Methods. The orthopedic problems and treatment of eight patients with PD from orthopedic consultation for neuromuscular disorders are retrospectively presented. We analyzed the problems of scoliosis, hip dysplasia, feet deformities, and contractures and presented the orthopedic treatment options. Results. Six of our eight PD patients had scoliosis and two young patients were treated by operative spine stabilization with benefits for posture and sitting ability. Hip joint surgery, operative contracture release, and feet deformity correction were performed with benefits for independent activity. Conclusion. Orthopedic management gains importance due to extended survival and musculoskeletal involvement under ERT. Surgical treatment is indicated in distinct cases. Further investigation is required to evidence the effect of surgical spine stabilization in PD.

    Chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) represent two of the most prevalent chronic respiratory disorders and cardiovascular diseases are major co-morbidities in both. Co-existence of both disorders (overlap syndrome) occurs in 1% of adults and overlap patients have worse nocturnal hypoxemia and hypercapnia than COPD and OSA patients alone. The present review discusses recent data concerning the pathophysiological and clinical significance of the overlap syndrome.

  20. Insulin Resistance in Patients with Chronic Kidney Disease

    2012-01-01

    Full Text Available Metabolic syndrome and its components are associated with chronic kidney disease (CKD development. Insulin resistance (IR plays a central role in the metabolic syndrome and is associated with increased risk for CKD in nondiabetic patients. IR is common in patients with mild-to-moderate stage CKD, even when the glomerular filtration rate is within the normal range. IR, along with oxidative stress and inflammation, also promotes kidney disease. In patients with end stage renal disease, IR is an independent predictor of cardiovascular disease and is linked to protein energy wasting and malnutrition. Systemic inflammation, oxidative stress, elevated serum adipokines and fetuin-A, metabolic acidosis, vitamin D deficiency, depressed serum erythropoietin, endoplasmic reticulum stress, and suppressors of cytokine signaling all cause IR by suppressing insulin receptor-PI3K-Akt pathways in CKD. In addition to adequate renal replacement therapy and correction of uremia-associated factors, thiazolidinedione, ghrelin, protein restriction, and keto-acid supplementation are therapeutic options. Weight control, reduced daily prednisolone dosage, and the use of cyclosporin decrease the risk of developing new-onset diabetes after kidney transplantation. Improved understanding of the pathogenic mechanisms underlying IR in CKD may lead to more effective therapeutic strategies to reduce uremia-associated morbidity and mortality.

    Environmental factors are an integral component in the pathogenesis of inflammatory bowel disease (IBD). There is an increasing interest in nutritive components. While the potential disease-modifying role of coffee has been intensively investigated in a variety of gastrointestinal diseases, the data on the potential impact on IBD is very limited. We aimed to determine the patients' perspective on coffee consumption in IBD. We conducted a questionnaire among IBD patients in Switzerland, assessing key questions regarding coffee consumption. Descriptive statistics including chi square testing were used for analysis of questionnaire data. Among a total of 442 patients 73% regularly consume coffee. 96% of patients attributing a positive and 91% of patients attributing no impact of coffee intake on IBD regularly drink coffee and surprisingly even 49% of those patients that assign a negative impact on disease symptoms. Among those patients refraining from regular coffee intake 62% are convinced that coffee adversely influences intestinal symptoms, significantly more in Crohn's disease (CD) than in ulcerative colitis (UC) (76% vs. 44%, p = 0.002). In total, 38% of all study subjects suppose that coffee has an effect on their symptoms of disease, significantly more in CD (54%) compared to UC patients (22%, p coffee has a detrimental influence, only 20% of UC patients share this impression (p coffee. More than twice as many CD compared to UC patients attribute a symptom-modifying effect of coffee consumption, the majority a detrimental one. However, this negative perception does not result in abstinence from coffee consumption.

    An association between celiac disease and renal diseases has been suggested, but the results are controversial. To investigate the prevalence of celiac disease autoimmunity among individuals undergoing renal biopsies and to evaluate whether co-existent celiac autoimmunity influences the clinical outcome of the renal disease. The prevalence of celiac autoimmunity (previous diagnosis of celiac disease or positive tissue transglutaminase antibodies) was determined in 827 consecutive patients undergoing kidney biopsies due to clinical indications. Up to 15 years' follow-up data on kidney function and co-morbidities were obtained. Celiac autoimmunity was found in 45 (5.4%) patients. Among the IgA nephropathy patients, 8.2% of had celiac autoimmunity. At the time of kidney biopsy and after a median follow-up of 5 to 6 years, renal function measured by estimated glomerular filtration rate (eGFR) was inferior in IgA nephropathy patients with celiac autoimmunity compared to those without it (P=0.048 and P=0.022, respectively). The prevalence of celiac autoimmunity seems to be high in patients undergoing renal biopsies, especially in patients with IgA nephropathy. Such autoimmunity may be associated with worse renal function in IgA nephropathy. Hence the co-existence of celiac disease should be taken into consideration when treating patients with renal diseases. Copyright © 2017 Editrice Gastroenterologica Italiana S.r.l.

    Improvements in the treatment of children with congenital heart disease have led to most of these patients reaching adulthood. Despite the increase in lifespan, very little is known about their quality of life - in particular, their ability to obtain a mortgage or consumer loan. To investigate the outcome of mortgage and loan applications made by adults with differential severities of congenital heart disease. Four hundred and seventy-six patients were invited to participate in a questionnaire-based interview by phone. Of these patients, one hundred and forty-two responded. Respondents were classified into three categories ('significant', 'complex' and 'mild') based on congenital heart disease severity according to the Bethesda conference. Ninety patients (64%) had applied for loans; 17 (16.5%) did not report their heart disease to the insurance company, 13 were refused insurance and 39 were asked to pay surplus fees. The imposed fees concerned patients classified in the 'significant' and 'complex' groups (Ploan had no influence on loan application outcomes. Adults with congenital heart disease are considerably more likely to have difficulty obtaining a mortgage or loan, independent of their congenital heart disease severity. Moreover, despite an increased obtainment of a loan in patients classified as 'mild', the refusal rates were identical for patients classified as having 'significant' or 'complex' congenital heart disease, although their prognosis is different.

    Purpose: To evaluate the utility of pulmonary magnetic resonance (MR) imaging with ultra-short echo times (UTEs) at a 3.0 T MR system for pulmonary functional loss and disease severity assessments of connective tissue disease (CTD) patients with interstitial lung disease (ILD). Materials and methods: This prospective study was approved by the institutional review board, and written informed consent was obtained from 18 CTD patients (eight men and ten women) and eight normal subjects with suspected chest disease (three men and five women). All subjects underwent thin-section MDCT, pulmonary MR imaging with UTEs, pulmonary function test and serum KL-6. Regional T2* maps were generated from each MR data set, and mean T2* values were determined from ROI measurements. From each thin-section MDCT data set, CT-based disease severity was evaluated with a visual scoring system. Mean T2* values for normal and CTD subjects were statistically compared by using Student's t-test. To assess capability for pulmonary functional loss and disease severity assessments, mean T2* values were statistically correlated with pulmonary functional parameters, serum KL-6 and CT-based disease severity. Results: Mean T2* values for normal and CTD subjects were significantly different (p = 0.0019) and showed significant correlations with %VC, %DL CO , serum KL-6 and CT-based disease severity of CTD patients (p < 0.05). Conclusion: Pulmonary MR imaging with UTEs is useful for pulmonary functional loss and disease severity assessments of CTD patients with ILD

    Full Text Available BACKGROUND Chronic kidney disease affects every organ system including the eye. The aim of the study is to conduct a thorough ocular examination and to study the occurrence of various ocular manifestations exhibited by patients with chronic kidney disease and to analyse the findings. MATERIALS AND METHODS 100 patients from Department of Nephrology, Stanley Medical College diagnosed with chronic kidney disease were examined for ocular manifestations at the Department of Ophthalmology, Stanley Medical College. This is a cross-sectional, descriptive, non-interventional, hospital-based study. The period of study was from August 2010 to October 2011. RESULTS The commonest cause of CKD was hypertension in 47 pts. (52.2% followed by both diabetes and hypertension in 30 patients. Patients with only diabetes were 6 patients (6.7% and with other causes were 7 patients (7.8%.10% of patients were legally blind with visual acuity <6/60. In this study, 65 patients belonged to less than 50 years. 49.3% of the presenile patients had cataract. A reduced Schirmer’s value was noted in 54 eyes of the 200 eyes. The incidence of ocular surface disease in the study was 27%. 92 eyes out of 200 eyes studied showed hypertensive retinopathy. Higher grades of hypertensive retinopathy was more in advanced stages of CKD, i.e. 24 eyes in stage IV and 23 eyes in stage V. 51 eyes out of 40 diabetics showed diabetic retinopathy changes of which a majority of 25 eyes belonged to stage V disease. Prevalence of diabetic retinopathy in CKD patients is significantly more when compared to diabetic patients without CKD. CONCLUSION Study demonstrates that routine ocular evaluation is necessary in all patients with chronic kidney disease irrespective of the presence of ocular symptoms. It also highlights the occurrence of a variety of treatable ocular manifestations, which can become vision threatening if not taken care of at the earliest.

  10. Resected Hepatocellular Carcinoma in a Patient with Crohn’s Disease on Azathioprine

    2016-05-01

    Full Text Available Hepatocellular carcinoma rarely occurs in patients without underlying cirrhosis or liver disease. While inflammatory bowel disease has been linked to certain forms of liver disease, hepatocellular carcinoma is exceedingly rare in these patients. We report the twelfth case of hepatocellular carcinoma in a patient with Crohn’s disease. The patient is a 61-year-old with longstanding Crohn’s disease who was treated with azathioprine and was found to have elevated liver enzymes and a new 3-cm liver mass on ultrasound. A complete workup for underlying liver disease was unremarkable and liver biopsy revealed hepatocellular carcinoma. The patient underwent a hepatic resection, and there is no evidence of recurrence at the 11-month follow-up. The resection specimen showed no evidence of cancer despite the initial biopsy revealing hepatocellular carcinoma. This case represents the third biopsy-proven complete spontaneous regression of hepatocellular carcinoma. Although large studies have failed to show a definite link between azathioprine and hepatocellular carcinoma, the relationship remains concerning given the multiple case reports suggesting a possible association. Clinicians should exercise a high degree of suspicion in patients with Crohn’s disease who present with elevated liver enzymes, especially those on azathioprine therapy.

  11. Are patients with coeliac disease seeking alternative therapies to a gluten-free diet?

    The cornerstone of treatment for coeliac disease is a gluten-free diet (GFD). However, adherence to a GFD is variable. Recently investigators have been reporting their preliminary findings using novel therapies. In addition, there is a growing interest in the use of complementary or alternative medicine (CAM) in gastrointestinal illnesses. These observations suggest that patients with coeliac disease may be dissatisfied with a GFD and possibly are seeking/using alternative therapies for their disease. Our aim was to assess the satisfaction levels of adults with coeliac disease towards a GFD, their use of oral CAM and views regarding novel therapies. 310 patients with coeliac disease completed a questionnaire survey while attending their out-patient appointment. The control group comprised 477 individuals. Over 40% of patients with coeliac disease were dissatisfied with a GFD. The frequency of CAM use in patients with coeliac disease was 21.6% (67/310) vs 27% in the control group (129/477), p=0.09. All patients expressed an interest in novel therapies, with a vaccine being the first choice in 42% of patients, 35% and 23% for anti- zonulin and peptidases, respectively. Universally, patients placed genetically modified wheat as the lowest preference. A large proportion of patients with coeliac disease are dissatisfied with a GFD. Coeliac patients are not taking CAM any more than controls, suggesting they do not view CAM as an alternative to a GFD. However, all the patients in this survey were keen to consider novel therapies, with a vaccine being the most preferred option.

    2018-02-01

    Full Text Available Background. Endometriosis is a comon, complex gynecological syndrom defined as the growth of endometrial glands and stroma in an extra-uterine location. It affects 5 – 20 % of women of reproductive age.1 Nowadays, prevailing opinion about endometriosis is based on presumption, that endometriosis is a result of changed immune system, according to autoimmune theory.2, 3 Characteristics of autoimmune disease that are also found in endometriosis are female preponderance, multiorgan involvement, family occurence, possible genetic basis, response to hormonal manipulation, tissue damage, polyclonal B lymphocite activation, immunological abnormalities in T lymphocite and B lymphocite function and associated autoimmune disease. Women with endometriosis are more frequently affected by asthma, rheumatoid arthritis, systemic lupus erythematosus, Sjögren syndrom and Hashimoto’s thyroiditis. Autoimmune disease is characterized by the production of autoantibodies against components of apoptotic cells. Anti-endometrial antibodies of IgG and IgM classes could be detected in 60 % of endometriosis patients. They show reactivity in glandular epithelium and stroma. Anti-endothelial antibodies specifically react with vascular endothelium and might be with anti-endometrial antibodies partially responsible for failure of implantation leading to infertility, wich is common in endometriosis patients. Anti-nuclear antibodies are frequent serological findings in patients with autoimmune disease, and could be detected in 29–47 % of women with endometriosis.4 Generation of anti-nuclear antibodies is a risk factor for development of other autoimmune disease in women of reproductive age. Studies have shown conflicting results on the presence of anti-ovarian antibodies in the serum of endometriosis patients and in the peritoneal fluid. Their presence is one of the possible causes of infertility. Conclusions. Ethiopathogenesis of endometriosis still remains uncelar but

    We analyzed the premorbid biographies of 21 patients with Alzheimer's disease for possible common features. Eleven age-matched patients suffering from vascular dementia served as a control group. The observations from our qualitative study indicate that persons with a conflict-avoiding, submissive, premorbid personality predominate among Alzheimer patients. Persons who later became Alzheimer patients tended to leave important daily-life decisions to their partners (or other persons of reference). Prior to the onset of the very first neuropsychological deficits, persons who later became Alzheimer patients were found to stay in a lasting situation in which they were subject to a treatment that could be designated as "caring tutelage." Subsequently, most patients became subject to an increasingly patronizing and restricting treatment. Further elements that were frequently found as part of the premorbid development were physical or psychological burden, loss of social contacts, and loss of motivation. In contrast, assertive and dominant premorbid traits predominated in the group of vascular patients. The premorbid biographical situation of persons who later became vascular patients was characterized by a loss of the control which these persons had hitherto exerted over partners, their families, or the situation at their working place. We advance the hypothesis that in Alzheimer's disease the described psychological phenomena are part of a preclinical process, during which biological, psychological, and social factors interact, finally joining into the clinical stage of the disease. Possibilities for psychotherapeutic interventions are discussed.

  14. The nature of alarm communication in Constrictotermes cyphergaster (Blattodea: Termitoidea: Termitidae: the integration of chemical and vibroacoustic signals

    Directory of Open Access Journals (Sweden)

    Paulo F. Cristaldo

    2015-12-01

    Full Text Available Alarm signalling is of paramount importance to communication in all social insects. In termites, vibroacoustic and chemical alarm signalling are bound to operate synergistically but have never been studied simultaneously in a single species. Here, we inspected the functional significance of both communication channels in Constrictotermes cyphergaster (Termitidae: Nasutitermitinae, confirming the hypothesis that these are not exclusive, but rather complementary processes. In natural situations, the alarm predominantly attracts soldiers, which actively search for the source of a disturbance. Laboratory testing revealed that the frontal gland of soldiers produces a rich mixture of terpenoid compounds including an alarm pheromone. Extensive testing led to identification of the alarm pheromone being composed of abundant monoterpene hydrocarbons (1S-α-pinene and myrcene, along with a minor component, (E-β-ocimene. The vibratory alarm signalling consists of vibratory movements evidenced as bursts; a series of beats produced predominantly by soldiers. Exposing termite groups to various mixtures containing the alarm pheromone (crushed soldier heads, frontal gland extracts, mixture of all monoterpenes, and the alarm pheromone mixture made of standards resulted in significantly higher activity in the tested groups and also increased intensity of the vibratory alarm communication, with the responses clearly dose-dependent. Lower doses of the pheromone provoked higher numbers of vibratory signals compared to higher doses. Higher doses induced long-term running of all termites without stops necessary to perform vibratory behaviour. Surprisingly, even crushed worker heads led to low (but significant increases in the alarm responses, suggesting that other unknown compound in the worker's head is perceived and answered by termites. Our results demonstrate the existence of different alarm levels in termites, with lower levels being communicated through

    Periodontal disease is characterized as a disorder of the oral microbiota resulting in an immune response which, in turn, leads to the destruction of periodontal tissue. Matrix metalloproteinase-8 (MMP-8) has been reported as the major metalloproteinase involved in periodontal disease, being present at high levels in gingival crevicular fluid and salivary fluid (SF). The aim of this systematic review was to evaluate the scientific literature regarding the expression of MMP-8 in gingival crevicular fluid and SF in patients with periodontal disease, analyzing its validity as a possible biomarker in the diagnosis of periodontal disease. A systematic review of the literature was performed using the PubMed/Medline, CENTRAL and Science Direct databases. Studies concerning the use of MMP-8 in the diagnosis of periodontal disease that evaluated its effectiveness as a biomarker for periodontal disease were selected. The search strategy provided a total of 6483 studies. After selection, six articles met all the inclusion criteria and were included in the present systematic review. The studies demonstrated significantly higher concentrations of MMP-8 in patients with periodontal disease compared with controls, as well as in patients presenting more advanced stages of periodontal disease. The findings on higher MMP-8 concentrations in patients with periodontal disease compared with controls imply the potential adjunctive use of MMP-8 in the diagnosis of periodontal disease. © 2017 John Wiley & Sons A/S.

    Objectives To ascertain the prevalence of Helicobacter pylori in patients with gastro-oesophageal reflux disease and its association with the disease. Design Systematic review of studies reporting the prevalence of H pylori in patients with and without gastro-oesophageal reflux disease. Data sources Four electronic databases, searched to November 2001, experts, pharmaceutical companies, and journals. Main outcome measure Odds ratio for prevalence of H pylori in patients with gastro-oesophageal reflux disease. Results 20 studies were included. The pooled estimate of the odds ratio for prevalence of H pylori was 0.60 (95% confidence interval 0.47 to 0.78), indicating a lower prevalence in patients with gastro-oesophageal reflux disease. Substantial heterogeneity was observed between studies. Location seemed to be an important factor, with a much lower prevalence of H pylori in patients with gastro-oesophageal reflux disease in studies from the Far East, despite a higher overall prevalence of infection than western Europe and North America. Year of study was not a source of heterogeneity. Conclusion The prevalence of H pylori infection was significantly lower in patients with than without gastro-oesophageal reflux, with geographical location being a strong contributor to the heterogeneity between studies. Patients from the Far East with reflux disease had a lower prevalence of H pylori infection than patients from western Europe and North America, despite a higher prevalence in the general population. What is already known on this topicThe relation between H pylori infection and gastro-oesophageal reflux disease is controversialStudies on the prevalence of H pylori in patients with gastro-oesophageal reflux disease have given conflicting resultsRecent guidelines recommend eradication of H pylori in patients requiring long term proton pump inhibitors, essentially for reflux diseaseWhat this study addsDespite heterogeneity between studies, the prevalence of H pylori was

These two surveys, based in Japan and the US, investigated the attitudes of patients towards antiparkinsonian medications, the complications of these therapies, and how these differ across geographies.Methods: The US PRELUDE survey collected data from May 13 to May 20, 2003, from 300 interviews with patients with Parkinson’s disease from the National Parkinson Foundation. The Japanese survey was carried out from June to December 2008 in a stepwise manner using questionnaires (n = 3548 followed by interviews with those who had consented to participate in the questionnaire (n = 407. Both surveys assessed the attitudes of patients towards therapies for Parkinson’s disease and associated complications.Results: Dyskinesia was not a major challenge of therapy for Parkinson’s disease, and wearing-off caused greater concern in the US, while hallucinations had a greater emphasis in Japan. Patients who had previously experienced dyskinesia were less concerned about this side effect than those who had not. Although pill burden was thought to be a concern in the US, Japanese patients did not indicate that pill burden would limit their drug intake. There were also discrepancies between the perspectives and concerns of patients and those of their treating physicians.Conclusion: Recognizing patient perspectives regarding therapies for

    Cerebral atrophy and regional cerebral blood flow (rCBF) of 25 patients with Parkinson's disease were studied. The rCBF was measured with the intra-arterial Xe-133 injection method. The results obtained were as follows: 1) Sixty four % of Parkinson's disease patients showed ventricular dilation, and 76% of Parkinson's disease patients showed cortical atrophy on the CT scan, but we had to allow for the effects of the natural aging process on these results. 2) No correlation was recognized either between cerebral atrophy and the severity of Parkinson's disease, or between cerebral atrophy and the duration of Parkinson's disease. 3) In Parkinson's disease patients, the mean rCBF was lower than that of normal control subjects. The difference was even more remarkable in older patients. Only 40% of Parkinson's disease patients showed hyperfrontal pattern. 4) There was no correlation either between the mean rCBF and the severity of Parkinson's disease, or between the mean rCBF and the duration of Parkinson's disease. There was no significant difference between the mean rCBF of Parkinson's disease patients receiving levodopa and that of untreated patients. 5) The mean rCBF decreased in patients with cerebral atrophy on the CT scan. 6) Parkinson's disease patients with intellectual impairment showed cerebral atrophy and a remarkable decrease of the mean rCBF. 7) The effect of aging on cerebral atrophy on the CT scan had to be allowed for, but judging from the decrease of the mean rCBF, the cerebral cortex is evidently involved in Parkinson's disease. 8) The rCBF decline in Parkinson's disease patients may be related with the diminished cortical metabolic rate due to a remote effect of striatal dysfunction and a disturbance of mesocortical dopaminergic pathways.

    Parkinson's disease is a chronic progressive neurodegenerative disorder with a multifactorial etiology. The symptoms are characterized by motor disorders - tremor, rigidity, bradykinesia and postural instability, which hinder oral hygiene. Oral and dental health in Parkinson's disease has been under-documented and findings are conflicting. Moreover, a number of dentists have limited experience regarding the management of these patients. This article reviews literature published within the last fifteen years, to better understand the impact of this disease in oral health. A literature search (MEDLINE and PUBMED), using keywords Parkinson Disease and Oral Hygiene, yielded 27 articles, from which 20 were selected. All of the articles were published in English in the last 15 years.

Some clinicians hypothesize that these often colorful dermal filaments are textile fibers, either self-implanted by patients or accidentally adhering to lesions, and conclude that patients with this disease have delusions of infestation. We present histological observations and electron microscopic imaging from representative Morgellons disease samples revealing that dermal filaments in these cases are keratin and collagen in composition and result from proliferation and activation of keratinocytes and fibroblasts in the epidermis. Spirochetes were detected in the dermatological specimens from our study patients, providing evidence that Morgellons disease is associated with an infectious process.Keywords: Morgellons disease, digital dermatitis, Lyme disease, Borrelia burgdorferi, spirochetes, keratin, keratinocytes, collagen, fibroblasts

    Accelerated formation and tissue accumulation of advanced glycation end products (AGEs), reflecting cumulative glycemic and oxidative stress, occurs in age-related and chronic diseases like diabetes mellitus (DM) and renal failure, and contributes to vascular damage. Skin autofluorescence (AFR), a noninvasive measurement method, reflects tissue accumulation of AGEs. AFR has been reported to be an independent predictor of mortality in Caucasian hemodialysis patients. We assessed the relationship between levels of AFR and the prevalence of cardiovascular disease (CVD), and clarified the prognostic usefulness of skin AFR levels in Asian (non-Caucasian) hemodialysis (HD) patients. AFR was measured with an autofluorescence reader in 64 HD patients. Overall and cardiovascular mortality was monitored prospectively during the 3-year follow-up. During follow-up, CVD events occurred in 21 patients. The deaths of 10 HD patients were associated with CVD. Multivariate logistic regression analyses showed that initial AFR was an independent risk factor for de novo CVD in HD patients with or without diabetes. When patients were classified on the basis of AFR tertiles, Cochran-Armitage analysis demonstrated that the highest tertile of AFR level showed an increased odds ratio for the prevalence of CVD. These findings suggest that AFR levels can be used to detect the prevalence of CVD in HD patients with or without diabetes. © 2014 The Authors.

    To identify the most common autoimmune rheumatic diseases in patients with autoimmune liver disease in the Hospital Arzobispo Loayza (HAL) from 2008 -2013. This is a transversal and descriptive study, we analyzed 125 medical records, only 86 patients fulfill the diagnostic criteria for autoimmune liver disease, of whom 46 had diagnosis of autoimmune hepatitis(AIH), 39 primary biliary cirrhosis(PBC) and just 1 primary sclerosing cholangitis (PSC). In our study group we looked for the clinical and laboratory characteristics most common and the frequency of cases in the HAL. Of the 46 patients with AIH, 16 (34.78%) were diagnosed with autoimmune rheumatic disease concurrence. Of these, 7 (15.22%) patients had Sjogren ́s Disease (SD), 6 (13.04%) had systemic lupus erythematosus (SLE) and 3 (6.52%) had rheumatoid arthritis (RA). We found 39 patients with PBC, 18 (46.15%) had other associated extrahepatic autoimmune disease, of whom 12 (30.77%) had SD, 3 (7.69%) SLE and 3 (7.69%) RA. One patient had the diagnosis of PSC, a sixty year old woman that had no concurrence with rheumatic disease. In our study was found that SD is the most common rheumatic disease in patients with AIH and PBC, followed by SLE and RA, with autoimmune liver disease with rheumatic symptoms and vice versa.

    The prevalence and perceived effectiveness of marijuana use has not been well studied in inflammatory bowel disease (IBD) despite increasing legal permission for its use in Crohn's disease. Health care providers have little guidance about the IBD symptoms that may improve with marijuana use. The aim of this study was to assess the prevalence, sociodemographic characteristics, and perceived benefits of marijuana use among patients with IBD. Prospective cohort survey study of marijuana use patterns in patients with IBD at an academic medical center. A total of 292 patients completed the survey (response rate = 94%); 12.3% of patients were active marijuana users, 39.0% were past users, and 48.6% were never users. Among current and past users, 16.4% of patients used marijuana for disease symptoms, the majority of whom felt that marijuana was "very helpful" for relief of abdominal pain, nausea, and diarrhea. On multivariate analysis, age and chronic abdominal pain were associated with current marijuana use (odds ratio [OR], 0.93; 95% confidence interval [CI], 0.89-0.97; P marijuana (OR, 0.93; 95% CI, 0.89-0.97; P marijuana for abdominal pain, were it legally available. A significant number of patients with IBD currently use marijuana. Most patients find it very helpful for symptom control, including patients with ulcerative colitis, who are currently excluded from medical marijuana laws. Clinical trials are needed to determine marijuana's potential as an IBD therapy and to guide prescribing decisions.

    Behçet disease (BD) is a systemic immune-mediated vasculitis of unknown origin characterised by recurrent orogenital ulceration, ocular inflammation and skin lesions. The aim of our study was to identify ear, nose and throat (ENT) manifestations associated with BD. Retrospective review of the medical records of all patients diagnosed with BD who attended a tertiary public hospital in Cantabria (Spain) over a period of 22 years. Clinical manifestations, in particular those concerning ENT, were retrieved from medical records. A medical literature review of ENT manifestations was conducted. Thirty-three patients (age range: 17-64 years) were included in the study. Most of them presented oral ulcers (97%). Eight patients (24%) presented oropharyngeal ulcers and 5 patients (15%) experienced audiovestibular symptoms (high frequency sensorineural hearing loss, vertigo and bilateral vestibular hypofunction). One patient had symptoms compatible with vestibular neuronitis as the presentation manifestation of Neuro-Behçet. In 4 patients (12%) the presence of odynophagia secondary to the presence of oropharyngeal lesions, initially interpreted as acute or recurrent tonsillitis, was the first manifestation of the disease, alone or associated with cutaneous or ocular lesions. In addition to the characteristic oral ulcers present in most patients with BD, ulcers in the oropharynx, occasionally interpreted as acute pharyngitis, are also common in these patients. Audiovestibular manifestations frequently appear during the course of the disease and may be the first symptom of central nervous system involvement. Copyright © 2013 Elsevier España, S.L.

    Outcome after cardiopulmonary resuscitation (CPR) in patients with underlying congenital heart disease is uncertain. This study aimed at evaluating outcome after CPR in patients with underlying congenital heart disease, factors related to worse outcome after CPR and whether survivors of sudden cardiac death (SCD) have a worse outcome when compared to an age, gender and disease-matched control population. Between 1984 and 2015, all patients with congenital heart disease who received in or out-of-hospital CPR were identified from the database of congenital heart disease from the University Hospitals Leuven. Postoperative and neonatal (CPR was excluded. For each survivor of SCD, two control patients matched for gender, age and underlying heart defect were included in the study. Thirty-eight patients (66% men; median age 25 years (interquartile range 9-40); 68% out-of-hospital) were identified, of which 27 (66%) survived the event. The main cause of SCD was ventricular tachycardia or fibrillation ( n=21). Heart defect complexity (odds ratio (OR) 5.1; 95% confidence interval (CI) 1.2-21.9; P=0.027), pulmonary hypertension (OR 13.8; 95% CI 2.1-89.5; P=0.006) and time to return of spontaneous circulation (OR 1.1; 95% CI 1.0-1.1; P=0.046) were related to worse outcome. Survivors of SCD had a worse prognosis when compared to an age, gender and disease-matched control group (5-year survival 76% vs. 98%; P=0.002). The complexity of underlying heart defect, pulmonary hypertension and time to return of spontaneous circulation are related to worse outcome in the case of CPR. Survivors of SCD have a worse outcome when compared to matched controls, indicating the need for adequate implantable cardioverter defibrillator indication assessment and for stringent follow-up of patients with worsening haemodynamics.

    Full Text Available Background Inflammatory Bowel Disease is known for its extra intestinal manifestations, the oral cavity is no exception. Objectives The aim of this study was to evaluate the association between Inflammatory Bowel Disease and oral mucosa lesions and symptoms, and complementary to evaluate their possible relation with oral hygiene, smoking habits, drug therapy, duration and activity of the disease. Methods Patients were selected from the Gastroenterology Clinic of a Portuguese tertiary referral hospital. This sample consisted of 113 patients previously diagnosed with ulcerative colitis or Crohn’s disease along with a control group of 58 healthy individuals that were accompanying the study group patients to their appointments. Clinical interviews and clinical examinations were performed for data collection. Results The patients in the study group were more affected by oral symptoms (P=0.011, and showed a trend towards a higher incidence of oral mucosal lesions, even though statistical significance was not reached (8.8% versus 3.4% in the control group; P=0.159. Patients in active phase were the most affected. No differences were detected between Crohn’s disease and ulcerative colitis, or concerning smoking habits. The corticosteroid and immunosuppressant therapy seemed to increase the incidence of oral symptoms (P=0.052. The oral mucosa lesions increased and the oral symptoms decreased over the course of the disease, however without statistical significance. Conclusion Oral mucosa’s lesions and oral symptoms were positively associated with Inflammatory Bowel Disease, mainly during disease activity periods and conceivably, associated with corticosteroid and immunosuppressant therapy.

    We evaluated the differences in diagnosis and treatment for primary hyperparathyroidism (pHPT) in patients with and those without concomitant thyroid disease. One hundred and ten patients with pHPT underwent parathyroid localization and thyroid examination by ultrasonography (US) and sestamibi scintigraphy (MIBI). The clinical and biochemical findings, parathyroid localization, and operations performed were compared in 49 patients without thyroid disease and 61 patients with thyroid disease. Asymptomatic hypercalcemia was significantly more prevalent in patients with concomitant thyroid disease (88.5%) than in those without thyroid disease (49.0%) (P<0.01). The mean serum calcium was significantly higher and the inorganic phosphate level was significantly lower in patients without concomitant thyroid disease than in those with concomitant thyroid disease (P<0.05, P<0.01, respectively). The pathologic parathyroid gland was identified significantly more often in patients without concomitant thyroid disease than in those with concomitant thyroid disease both by US and MIBI (P<0.05). Unilateral exploration was performed more often in patients without thyroid disease than in those with thyroid disease (P<0.01). Primary hyperparathyroidism was diagnosed at an earlier stage in patients with concomitant thyroid disease. Thyroid disease concomitant with pHPT influenced parathyroid localization as well as the indication for minimally invasive parathyroidectomy. (author)

    Full Text Available The concept of drug discovery through stem cell biology is based on technological developments whose genesis is now coincident. The first is automated cell microscopy with concurrent advances in image acquisition and analysis, known as high content screening (HCS. The second is patient-derived stem cells for modelling the cell biology of brain diseases. HCS has developed from the requirements of the pharmaceutical industry for high throughput assays to screen thousands of chemical compounds in the search for new drugs. HCS combines new fluorescent probes with automated microscopy and computational power to quantify the effects of compounds on cell functions. Stem cell biology has advanced greatly since the discovery of genetic reprogramming of somatic cells into induced pluripotent stem cells (iPSCs. There is now a rush of papers describing their generation from patients with various diseases of the nervous system. Although the majority of these have been genetic diseases, iPSCs have been generated from patients with complex diseases (schizophrenia and sporadic Parkinson’s disease. Some genetic diseases are also modelled in embryonic stem cells generated from blastocysts rejected during in vitro fertilisation. Neural stem cells have been isolated from post-mortem brain of Alzheimer’s patients and neural stem cells generated from biopsies of the olfactory organ of patients is another approach. These olfactory neurosphere-derived cells demonstrate robust disease-specific phenotypes in patients with schizophrenia and Parkinson’s disease. High content screening is already in use to find small molecules for the generation and differentiation of embryonic stem cells and induced pluripotent stem cells. The challenges for using stem cells for drug discovery are to develop robust stem cell culture methods that meet the rigorous requirements for repeatable, consistent quantities of defined cell types at the industrial scale necessary for high

    Laser Doppler flowmetry (LDF) has been applied for the assessment of variation in blood microflows in patients with rheumatic diseases and healthy volunteers. Oscillations of peripheral blood microcirculation observed by LDF have been analyzed utilizing a wavelet transform. A higher amplitude of blood microflow oscillations has been observed in a high frequency band (over 0.1 Hz) in patients with rheumatic diseases. Oscillations in the high frequency band decreased in healthy volunteers in response to the cold pressor test, whereas lower frequency pulsations prevailed in patients with rheumatic diseases. A higher perfusion rate at normal conditions was observed in patients, and a weaker response to cold stimulation was observed in healthy volunteers. Analysis of blood microflow oscillations has a high potential for evaluation of mechanisms of blood flow regulation and diagnosis of vascular abnormalities associated with rheumatic diseases.

    Full Text Available Introduction: Human functioning is based on physical, psychological, social and spiritual areas. The emergence of cancer and all types of problems affect these areas. Adapting to cancer is very important for the process of therapy, and acceptance of the disease is its determinant. Aim of the research study : To determine the relationship between oncological patients physical fitness and their acceptance of the disease. Material and methods: The following research techniques and tools have been used: a questionnaire survey, the Repta operation scale for assessing the functionality of patients in the course of the disease, a modified Pain Assessment Worksheet for evaluating the intensity of pain and its impact on daily activities and the AIS scale to assess the degree of acceptance of the disease. Results: Most of the respondents were fully efficient in the field of the activities of daily living. The vast majority of respondents did not feel pain, or felt pain that could be taken lightly. Pain that made daily functioning difficult, particularly in mobility and locomotion, concerned only persons over 60 years old. In the study group there was dominantly an average degree of acceptance of the disease; a small group was marked by a high level, and only a few people showed a lack of acceptance of the disease. Independent people and people in need of assistance accepted the illness at a medium level, and vulnerable patients showed the lowest level of acceptance. Conclusions : The efficiency of patients with cancer affects the level of acceptance of the disease. Cancer for the majority of respondents is not an obstacle in performing basic activities. Most respondents accept the disease, a small part selects a high level, and only a few people show a lack of acceptance of the disease.

    Current surgical indications for Graves' disease include intractability to medical and/or radioablative therapy, compressive symptoms, and worsening ophthalmopathy. Total thyroidectomy for Graves' disease may be technically challenging and lead to untoward perioperative outcomes. This study examines outcomes in patients with Graves' disease who underwent total thyroidectomy and assesses its safety for this patient population. A retrospective cross-sectional analysis was performed using the Nationwide Inpatient Sample database from 2006 to 2011. Total thyroidectomy performed in patients with Graves' disease, benign multinodular goiter (MNG), and thyroid cancer was identified. Demographic factors, comorbidities, and postoperative complications were evaluated. Chi-square, one-way analysis of variance, and risk-adjusted multivariable logistic regression were performed. Of 215,068 patients who underwent total thyroidectomy during the study period, 11,205 (5.2%) had Graves' disease, 110,124 (51.2%) MNG, and 93,739 (43.6%) thyroid malignancy. Patients with Graves' disease were younger than MNG and thyroid cancer patients (M age  = 42.8 years vs. 55.5 and 51.0 years; p Graves' disease group included a higher proportion of women (p Graves' disease was independently associated with a higher risk of vocal-cord paralysis (odds ratio [OR] = 1.36 [confidence interval (CI) 1.08-1.69]), tracheostomy (OR = 1.35 [CI 1.1-1.67]), postoperative hypocalcemia (OR = 1.65 [CI 1.54-1.77]), and hematoma requiring reoperation (OR = 2.79 [CI 2.16-3.62]) compared to MNG patients. High-volume centers for total thyroidectomy were independently associated with lower risk of postoperative complications, including in patients with Graves' disease. Despite low overall morbidity following total thyroidectomy, Graves' disease patients are at increased risk of postoperative complications, including bleeding, vocal-cord paralysis, tracheostomy, and hypocalcemia. These risks appear

    Crohn's disease (CD) is a chronic inflammatory condition that plagues millions all over the world. This debilitating bowel disease can start in early childhood and continue into late adulthood. Signs and symptoms are usually many and multiple tests are often required for the diagnosis and confirmation of this disease. However, little is still understood about the cause(s) of CD. As a result, several theories have been proposed over the years. One theory in particular is that Mycobacterium avium subspecies paratuberculosis (MAP) is intimately linked to the etiology of CD. This fastidious bacterium also known to cause Johne's disease in cattle has infected the intestines of animals for years. It is believed that due to the thick, waxy cell wall of MAP it is able to survive the process of pasteurization as well as chemical processes seen in irrigation purification systems. Subsequently meat, dairy products and water serve as key vehicles in the transmission of MAP infection to humans (from farm to fork) who have a genetic predisposition, thus leading to the development of CD. The challenges faced in culturing this bacterium from CD are many. Examples include its extreme slow growth, lack of cell wall, low abundance, and its mycobactin dependency. In this review article, data from 60 studies showing the detection and isolation of MAP by PCR and culture techniques have been reviewed. Although this review may not be 100% comprehensive of all studies, clearly the majority of the studies overwhelmingly and definitively support the role of MAP in at least 30%-50% of CD patients. It is very possible that lack of detection of MAP from some CD patients may be due to the absence of MAP role in these patients. The latter statement is conditional on utilization of methodology appropriate for detection of human MAP strains. Ultimately, stratification of CD and inflammatory bowel disease patients for the presence or absence of MAP is necessary for appropriate and effective

    Objectives: To prospectively assess dynamic contrast-enhanced (DCE-)MRI as compared to conventional sequences in patients with luminal Crohn's disease. Methods: Patients with Crohn's disease undergoing MRI and ileocolonoscopy within 1 month had DCE-MRI (3T) during intravenous contrast injection of gadobutrol, single shot fast spin echo sequence and 3D T1-weighted spoiled gradient echo sequence, a dynamic coronal 3D T1-weighted fast spoiled gradient were performed before and after gadobutrol. Maximum enhancement (ME) and initial slope of increase (ISI) were calculated for four colon segments (ascending colon + coecum, transverse colon, descending colon + sigmoid, rectum) and (neo)terminal ileum. C-reactive protein (CRP), Crohn's disease activity index (CDAI), per patient and per segment Crohn's disease endoscopic index of severity (CDEIS) and disease duration were determined. Mean values of the (DCE-)MRI parameters in each segment from each patient were compared between four disease activity groups (normal mucosa, non-ulcerative lesions, mild ulcerative and severe ulcerative disease) with Mann-Whitney test with Bonferroni adjustment. Spearman correlation coefficients were calculated for continuous variables. Results: Thirty-three patients were included (mean age 37 years; 23 females, median CDEIS 4.4). ME and ISI correlated weakly with segmental CDEIS (r = 0.485 and r = 0.206) and ME per patient correlated moderately with CDEIS (r = 0.551). ME was significantly higher in segments with mild (0.378) or severe (0.388) ulcerative disease compared to normal mucosa (0.304) (p < 0.001). No ulcerations were identified at conventional sequences. ME correlated with disease duration in diseased segments (r = 0.492), not with CDAI and CRP. Conclusions: DCE-MRI can be used as a method for detecting Crohn's disease ulcerative lesions.

    Chronic disease is recognized as having a large impact on patient quality of life (QoL), which can be defined as an individual's satisfaction or happiness with life in domains he or she considers important. Policy makers and clinicians recognize increasingly that patients can safeguard their QoL by making healthy lifestyle choices and being actively engaged in their health care. However, in the emphasis on promoting patient engagement to enhance patients' QoL, there is no consensus regarding the relationship between QOL and patient engagement, resulting in a lack of shared guidelines among clinicians on interventions. Furthermore, no studies have provided an in-depth exploration of the perspective of patients with chronic conditions who are engaged in their health care and their requirements to achieve an improved QoL. Given this theoretical gap, the present study attempted to explore the patient engagement experience and its relationship with patient QoL in the context of the Italian healthcare system and in relation to different chronic diseases. In-depth qualitative interviews on a sample of 99 patients with a wide variety of chronic conditions (heart failure, chronic obstructive pulmonary disease, stroke, diabetes, and cancer). Patient engagement in health care can be defined as a context-based and cross-disease process that appears to enable patients to recover their life projectuality, which had been impaired by the onset of chronic disease. Successful patient engagement may also be related to a positive shift in the ways in which patients perceive self and life and experience empowerment to realize their life potential, thus improving quality of life. Patient engagement is a powerful concept capable of reflecting significant psychosocial changes that promote patient QoL along the care process. There appears to be theoretical and empirical justification for a broad definition of QoL. QoL deeply depends on the patient ability to engage in their care and on the

    The aim of the study was to identify the prevalence of HFE gene mutations in Czech patients with chronic liver diseases and the influence of the mutations on iron status. The presence of HFE gene mutations (C282Y, H63D, and S65C) analyzed by the PCR-RFLP method, presence of cirrhosis, and serum iron indices were compared among 454 patients with different chronic liver diseases (51 with chronic hepatitis B, 122 with chronic hepatitis C, 218 with alcoholic liver disease, and 63 patients with hemochromatosis). Chronic liver diseases patients other than hemochromatics did not have an increased frequency of HFE gene mutations compared to controls. Although 33.3% of patients with hepatitis B, 43% of patients with hepatitis C, and 73.2% of patients with alcoholic liver disease had elevated transferrin saturation or serum ferritin levels, the presence of HFE gene mutations was not significantly associated with iron overload in these patients. Additionally, patients with cirrhosis did not have frequencies of HFE mutations different from those without cirrhosis. This study emphasizes the importance, not only of C282Y, but also of the H63D homozygous genetic constellation in Czech hemochromatosis patients. Our findings show that increased iron indices are common in chronic liver diseases but {\\it HFE} mutations do not play an important role in the pathogenesis of chronic hepatitis B, chronic hepatitis C, and alcoholic liver disease.

    BACKGROUND: Epidemiologic shift with rising incidence of Crohn\\'s disease (CD) has been reported in recent studies. AIMS: To determine disease behaviour and therapeutic interventions undertaken in newly diagnosed patients with CD. METHODS: Patients diagnosed with CD between January 2006 and June 2008 were included. Disease type, location, degree of involvement and type of therapeutic interventions were recorded. RESULTS: A total of 78 patients were included. Colonic, ileo-colonic, terminal ileal and isolated small bowel disease were present in 37, 27, 9 and 5 patients, respectively. Disease phenotype was inflammatory, stenosing and fistulising in 42, 30 and 6 patients, respectively. Surgery was required in 22 patients, including right hemicolectomy (n = 8), subtotal colectomy (n = 4), segmental colonic resection (n = 2), segmental small bowel resection (n = 2), appendectomy (n = 2) and perianal surgery (n = 4). Fourteen patients underwent surgery at the time of diagnosis. Laparoscopic surgery was performed in 14 patients. CONCLUSIONS: A significant proportion of newly diagnosed patients with CD underwent surgical intervention on their first admission to hospital. This may signify a changing trend in the management approach.

    The risk for contrast-induced nephropathy (CIN) after intra-arterial application of an iodine-based contrast material is unknown for patients with chronic kidney disease (CKD) and peripheral arterial disease (PAD). To investigate the incidence of CIN in patients with CKD and PAD. This retrospective study was approved by the local ethics committee. One hundred and twenty patients with 128 procedures (73 with baseline eGFR in the range of 45–60 mL/min/1.73m 2 , 55 with eGFR < 45 mL/min/1.73m 2 ) were evaluated. All patients received intra-arterially an iodine-based low-osmolar contrast material (CM) after adequate intravenous hydration with isotonic NaCl 0.9% solution. CIN was defined as an increase in serum creatinine of more than 44 μmol/L within 4 days. The influence of patient-related risk factors (age, weight, body mass index, eGFR, serum creatinine, hypertension, diabetes mellitus, coronary heart disease, heart failure) and therapy-related risk factors (amount of CM, nephrotoxic drugs, number of CM applications) on CIN were examined. CIN developed in 0% (0/73) of procedures in patients with PAD and an eGFR in the range of 45–60 mL/min/1.73m 2 and in 10.9% (6/55) of procedures in patients with an eGFR <45 mL/min/1.73m 2 . No risk factor significantly influenced the development of CIN, although baseline serum creatinine (P = 0.06) and baseline eGFR (P = 0.10) showed a considerable dependency. Patients with an eGFR in the range of 45–60 mL/min/1.73m 2 and PAD seem not at risk for CIN after intra-arterial CM application and adequate hydration. Whereas, an eGFR < 45 mL/min/1.73m 2 correlated with a risk of 10.9% for a CIN

    Sexual dysfunction (SD) is common among patients with Parkinson's disease (PD), Alzheimer's disease (AD), and other dementias. Sexual functioning and well-being of patients with PD and their partners are affected by many factors, including motor disabilities, non-motor symptoms (e.g., autonomic dysfunction, sleep disturbances, mood disorders, cognitive abnormalities, pain, and sensory disorders), medication effects, and relationship issues. The common sexual problems are decreased desire, erectile dysfunction, difficulties in reaching orgasm, and sexual dissatisfaction. Hypersexuality is one of a broad range of impulse control disorders reported in PD, attributed to antiparkinsonian therapy, mainly dopamine agonists. Involvement of a multidisciplinary team may enable a significant management of hypersexuality. Data on SD in demented patients are scarce, mainly reporting reduced frequency of sex and erectile dysfunction. Treatment of SD is advised at an early stage. Behavioral problems, including inappropriate sexual behavior (ISB), are distressing for patients and their caregivers and may reflect the prevailing behavior accompanying dementia (disinhibition or apathy associated with hyposexuality). The neurobiologic basis of ISB is still only vaguely understood but assessment and intervention are recommended as soon as ISB is suspected. Management of ISB in dementia demands a thorough evaluation and understanding of the behavior, and can be treated by non-pharmacologic and pharmacologic interventions. © 2015 Elsevier B.V.

    This study aimed at examining the impact of Parkinson disease (PD) on patients' sexuality and relationship and to evaluate gender-specific differences. Using a standardized questionnaire on sexual functioning in chronic diseases (SFCE), the impact of PD diagnosis on 38 domains of sexuality before and since PD diagnosis was evaluated retrospectively in 53 consecutive patients in a relationship. Changes in self-assessed ratings on a four-point Likert scale were determined for all patients. In addition, gender-specific differences and the influence of age, depression (BDI-II), medication, disease severity and disease duration on domains of the SFCE were calculated. The importance of non-sexual relational aspects, such as talking about feelings or tenderness increased for both genders after PD diagnosis, especially in women. Sexual function, such as frequency of intercourse, sexual arousal, subjective abnormal sexual fantasies or sexual satisfaction deteriorated in both genders, especially in men. Some sexual aspects improved in women but worsened in men after PD diagnosis. This includes frequency of orgasm dysfunction, fear not to fulfill sexual expectations of the partner, avoidance of sexual acts, withdrawal from relationship, increase of thoughts about divorce, or increase of dissatisfaction with sexuality and relationship. With age, thoughts about divorce declined. With disease duration, frequency of tenderness with the partner increased. Depression unexpectedly correlated with higher frequency of intercourse. Dopaminergic dosage influenced stability of the relationship negatively. PD influences patients' sexuality negatively, independently of age, disease duration or disease severity and men show greater sexual dysfunction and impairment of their sexual relationship than women.

    Cardiovascular disease remains the primary cause of diabetes-associated morbidity and mortality. Previous studies have failed to provide accurate, inexpensive, screening techniques to detect cardiovascular disease in diabetics. Ankle brachial indices (ABI) testing may be an effective screening technique for diabetics. The aim of this 100-subject clinical study was to determine cardiovascular disease prevalence, via perfusion stress testing, in diabetic patients having abnormal ABI (<0.90) and without known heart disease who were referred to the South Carolina Heart Center, Columbia, SC for nuclear perfusion stress testing. Study data were analyzed using frequency and descriptive statistics and 2-sample T-testing. Mean subject age was 62+/-11 years, ABI 0.76+/-13, and ejection fraction 60+/-12%. Perfusion stress testing detected 49 abnormal electrocardiograms, 36 subjects with coronary ischemia, 20 with diminished left ventricular function, and 26 subjects having significant thinning of the myocardium. There were 71 subjects who tested positive for at least one form of cardiovascular disease. The sole predictive variable reaching significance for the presence of cardiovascular disease was an ABI score <0.90 (p< or =0.0001). Cardiovascular disease may be predicted among diabetic patients via ABI scores and confirmed by nuclear perfusion testing.

    To summarize the clinical features of different racial patients with celiac disease (CD) and analyze the disease prevalence, diagnosis and treatment in Chinese population. All the patients were diagnosed as CD and enrolled in Beijing United Family Hospital between January 2005 and July 2015.Clinical data including nationality, age, symptoms, endoscopic and pathological findings, outcome were collected and compared in patients from different countries. A total of 87 patients were enrolled including 63 Caucasians, 18 Asian patients and 6 Middle East patients.The peak age of disease onset was 40-60 years old.Patients with typical symptoms such as chronic diarrhea and weight loss only accounted for 20.7%(18/87) and 9.2%(8/87) respectively.Some patients presented with nonspecific symptoms such as abdominal pain and bloating [32.2%(28/87)], even constipation [5.7%(5/87)].13.8%(12/87) patients were previously diagnosed as irritable bowel syndrome.The incidence of abdominal pain, bloating, diarrhea and constipation between Asians and Caucasians had no statistical significance (P>0.05); but the proportions of weight loss, growth retardation, iron deficiency anemia and dermatitis herpetiformis in Asian group were significantly higher than that in Caucasian group (Pceliac disease antibodies in 47 patients turned negative from 6-9 months after GFD treatment, while 34 patients turned negative from 12-18 months after GFD.All patients reported disease remission to some extent.After 1 year GFD treatment, the pathology of endoscopic intestinal biopsy in 8 patients showed significant improvement of villous atrophy and lymphocyte infiltration. CD patients with typical clinical manifestations are not the majority.Serological celiac disease antibodies (AGA, EMA and tTGA) have a high diagnostic value.GFD treatment is effective on majority of celiac patients.Clinical manifestations, endoscopy, intestinal pathology, and response to GFD in Chinese patients are not the same as Caucasians

    The aims of this study were to find the characteristics and prevalence of nailfold capillary changes in a large series of patients with Behçet's disease (BD) and to analyze their possible relation to other clinical characteristics of the disease. We performed nailfold capillaroscopy in 128 randomly selected patients fulfilling the international classification criteria for BD. Capillaroscopy was done in eight fingers with a x3.2 microscopy. All patients were questioned for history of Raynaud's phenomenon, ischemic ulcers, smoking, and hypertension. A computerized form including demographic, clinical, and para-clinical features was used to collect data. Univariate and multivariate logistic regressions were used to analyze the relation between capillaroscopic findings and disease characteristics. Odds ratio and a confidence interval at 95% (CI) were calculated for each item. The mean age of the patients was 37 +/- 10 years, and the male to female ratio was 1.56:1. Capillaroscopy was abnormal in 51 patients (40%, CI 8.5). Enlarged capillaries were seen in 33 patients (26%, CI 7.6), hemorrhages in 21 (16%, CI 6.4), and capillary loss only in one patient. In univariate logistic regression analysis, the presence of enlarged capillaries was associated with lower age at disease onset (OR = 0.9, CI 0.9-1; p = 0.04), hypertension (OR = 4.2, CI 1.5-11.4; p = 0.006), superficial phlebitis (OR = 5.5, CI 1.2-24.4; p = 0.03), and negative pathergy test (OR = 0.4, CI 0.2-0.9; p = 0.04). The presence of hemorrhages tended to be associated with articular symptoms (p = 0.05). Multivariate analysis also confirmed the association of enlarged capillaries with lower age at disease onset (p = 0.01), hypertension (p = 0.001), and superficial phlebitis (p = 0.03). Nailfold abnormalities, mainly enlarged capillaries, are frequent in patients with BD. Our results suggest that these abnormalities may be related to other vascular features of the disease such as superficial phlebitis, but it

    The aim of this study was to describe pancreatic involvement in von Hippel-Lindau (VHL) disease and to document the changes that occur in pancreatic lesions. We retrospectively analyzed the medical records and CT scans of 18 VHL patients who were diagnosed between 1994 and 2007 at the Samsung Medical Center. The clinical history with a detailed family history, biochemical test results, and imaging studies of the pancreas, adrenal glands, and kidneys were reviewed. Genetic analysis was performed in 12 patients. The changes in pancreatic lesions, such as an increase in cystic lesions, calcifications, and dilatation of the pancreatic duct, were analyzed in patients who had CT scans at least 1 year apart. Pancreatic lesions existed in 89% (16/18) of the patients. All 16 patients had multiple cystic lesions. Two patients had co-existing neuroendocrine tumors (NET), and two patients had co-existing serous cystadenomas (SCA). At least one of three features of pancreatic lesions (cystic lesions, calcifications, and dilatation of the pancreatic duct) progressed in all nine patients who had CT scans 1 year apart. Pancreatic involvement in VHL disease was relatively common in Korean patients. The most common type of pancreatic involvement was a multiple cystic lesion. NET and SCA existed in approximately 10% of VHL patients with pancreatic involvement. Pancreatic lesions in VHL disease progressed, at least according to radiological images. (author)

    Background: Renal artery stenosis (RAS) is a common finding in patients undergoing coronary angiography. We designed this study to look for the frequency and any predictors of renal artery stenosis in patients with coronary artery disease (CAD). Methods: A total of 201 consecutive patients with CAD confirmed by coronary angiography underwent an abdominal aortogram in the same sitting to screen for RAS. Patient demographics and co-morbidities were analysed for any association with RAS. Results: Forty-one of the patients were female (20.4%); ninety patients were hypertensive (44.8%); 49 patients (24.4%) were smokers; 19 patients (9.5%) had renal insufficiency; 88 patients (43.8%) had high cholesterol levels; 44 patients (21.9%) were diabetic. Thirty-two patients (15.9%) had single coronary artery disease, 59 patients (29.4%) had two vessel disease, and 110 patients (54.7%) had three vessel disease. Significant renal artery stenosis (less or equal to 50% stenosis) was present in 26 patients (12.9%). Among the variables studied, only female gender was found to be associated with a higher frequency of renal artery stenosis (24.39% vs 10.0%, p=0.01). Conclusions: The frequency of renal artery stenosis in patients with coronary artery disease is 12.9%. Female gender is associated with a higher frequency of renal artery stenosis in patients with CAD. (author)

    Early identification of patients with Crohn's disease (CD) at risk of subsequent complications is essential for adapting the treatment strategy. We aimed to develop a prediction model including clinical and serological markers for assessing the probability of developing advanced disease in a prospective referral CD cohort. Two hundred and seventy-one consecutive CD patients (42.4% males, median follow-up 108 months) were included and followed up prospectively. Anti-Saccharomyces cerevisiae antibodies (ASCA IgA/IgG) were determined by enzyme-linked immunosorbent assay. The final analysis was limited to patients with inflammatory disease behaviour at diagnosis. The final definition of advanced disease outcome was having intestinal resection or disease behaviour progression. Antibody (ASCA IgA and/or IgG) status, disease location and need for early azathioprine were included in a 3-, 5- and 7-year prediction matrix. The probability of advanced disease after 5 years varied from 6.2 to 55% depending on the combination of predictors. Similar findings were obtained in Kaplan-Meier analysis; the combination of ASCA, location and early use of azathioprine was associated with the probability of developing advanced disease (p < 0.001, log rank test). Our prediction models identified substantial differences in the probability of developing advanced disease in the early disease course of CD. Markers identified in this referral cohort were different from those previously published in a population-based cohort, suggesting that different prediction models should be used in the referral setting.

    Full Text Available INTRODUCTION Castleman disease was for the first time described in 1956 as a mediastinal tumour mass. Etiology of this disease is still unknown. The disease can be solitary and multicentric or rarely of a mixed type. The former is often of hyaline vascular type, while the latter is of plasma cell type. CASE REPORT Castleman disease was diagnosed in a 26-year old male patient when a well defined shadow was incidentally detected in the middle lobe of the right lung. A year before, he was diagnosed with allergic rhinitis to Ambrosia. Two years after surgery the patient was feeling well, and was without any recurrence, however, allergic rhinitis still persisted. CONCLUSION Castleman disease can occur in any organ containing lymph tissues. Most frequently the disease is described as mediastinal, rarely as an intrapulmonary tumorous mass, and it is most frequently seen in younger persons. The solitary type of Castleman disease is surgical treatable with a prospect of good prognosis, while the multicentric and mixed types recur despite treatment with cortisone, irradiation and cytostatics. As the association between Castleman disease and allergic diseases has not been confirmed up-tonow, it could be concluded that this patient suffered from two separated diseases.

    Subthalamic nucleus (STN) deep brain stimulation (DBS) is an established treatment for patients with advanced Parkinson disease. However, some patients feel less satisfied with the outcome of surgery. We sought to study the relationship between expectations, satisfaction, and outcome in STN DBS for Parkinson disease. Twenty-two consecutive patients undergoing STN DBS completed a modified 39-item Parkinson disease questionnaire (PDQ-39) preoperatively and 6 months postoperatively. A satisfaction questionnaire accompanied the postoperative questionnaire. Patients expected a significant improvement from surgery preoperatively: preoperative score (median PDQ-39 summary score [interquartile range]): 37.0 (9.5), expected postoperative score: 13.0 (8.0), P Parkinson disease.

    Full Text Available Nodular regenerative hyperplasia (NRH of the liver is often associated with rheumatologic or lymphoproliferative disorders and a cause of portal hypertension in some patients. We report the case of a 71-year-old patient with celiac disease and unexplained portal hypertension. Biopsy of the liver revealed NRH as the underlying cause. The patient did not suffer from an autoimmune, rheumatologic or lymphoproliferative disease. A thrombophilic disorder that might cause NRH was ruled out. Celiac disease is often associated with mild elevation of liver enzymes and steatosis of the liver, but the association with NRH was described in only a few patients. We discuss the possible relationship of celiac disease and NRH.

    The article deals with the problem of osteoporosis in patients with cardiovascular and broncho-obstructive disease. The risk factors and clinical functional features of osteoporosis are analyzed in patients with coronary heart disease, hypertension, chronic obstructive pulmonary disease, bronchial asthma. Indicators of bone mineral density in patients with cardiovascular and broncho-obstructive disease on average meet the criteria for osteopenia. Most examinees had a high risk of osteoporotic fractures as a result of significant reduction in bone mineral density. The presence of osteoporosis in patients with cardiovascular and broncho-obstructive pathology from the point of co-morbidity results in a syndrome of mutual aggravation that determines the need for a comprehensive diagnosis, treatment and prevention.
