    In 2003 new computer software, the VOAA (Video Observations Aarts and Aarts), was designed to score and evaluate two important aspects of spontaneous upper limb use, i.e. overall duration and frequency of specific behaviours. The aim of this study was to investigate the test-retest, interrater and intrarater reliability and the construct validity of a new module, the VOAA-DDD, to determine developmental disregard in children with spastic unilateral cerebral palsy (CP). A test-retest design with three raters for reliability and a two-group design for construct validity were used. Subjects were a total of 20 children with spastic unilateral CP equally divided in two age groups (2.5-5 and 5-8 years), and 56 healthy children of the same age groups. Overall duration and frequency of specific behaviours of the affected arm and hand were assessed during a task demanding ('stringing beads') and a task stimulating ('decorating a muffin') the use of both hands. Reliability was estimated by intraclass correlation coefficients (ICCs). Construct validity was assessed by comparing children with CP to healthy children. All ICCs exceeded 0.87. In contrast with healthy children, children with CP used their affected hand less during the 'muffin' task compared to the 'beads' task. Of the children with CP, 90% in the age group of 2.5-5 years and 50% in the age group of 5-8 years showed values exceeding the extreme values of healthy controls, respectively, indicating developmental disregard. The VOAA-DDD is a reliable and valid instrument to assess spontaneous use of the affected arm and hand in order to determine developmental disregard in children with spastic unilateral CP.

    In this article, we present a novel experimental approach to the study of anticipation in probabilistic cuing. We implemented a modified spatial cuing task in which participants made an anticipatory hand movement toward one of two probabilistic targets while the (x, y)-computer mouse coordinates of their hand movements were sampled. This approach allowed us to tap into anticipatory processes as they occurred, rather than just measuring their behavioral outcome through reaction time to the target. In different conditions, we varied the participants' degree of certainty of the upcoming target position with probabilistic pre-cues. We found that participants initiated spontaneous anticipatory hand movements in all conditions, even when they had no information on the position of the upcoming target. However, participants' hand position immediately before the target was affected by the degree of certainty concerning the target's position. This modulation of anticipatory hand movements emerged rapidly in most participants as they encountered a constant probabilistic relation between a cue and an upcoming target position over the course of the experiment. Finally, we found individual differences in the way anticipatory behavior was modulated with an uncertain/neutral cue. Implications of these findings for probabilistic spatial cuing are discussed.

    Compartment syndrome refers to a condition of compromised circulation within a limited space due to increased pressure within that space. The reduced tissue perfusion results in reduced venous drainage, leading to increased interstitial tissue pressure and subsequent compromised arterial flow. Although not as common as compartment syndrome of the leg and forearm, compartment syndrome of the hand is not rare and can lead to devastating sequelae as a result of tissue necrosis. Compartment syndrome of the hand has several etiologies, including trauma, arterial injury, thermal injury, and constrictive bandaging. The cardinal clinical sign is pain that is aggravated by passive stretching of the muscles within the involved compartments. Extremity function is usually restored with expeditious fasciotomy of the involved myofascial compartments, and complications, such as intrinsic muscular dysfunction and Volkmann's ischemic contracture, can usually be prevented. There are no reported cases of compartment syndrome of the hand in patients with systemic sclerosis or Raynaud's phenomenon. Systemic sclerosis is a form of scleroderma that affects the skin and internal organs. The limited cutaneous subset affects the skin of the extremities but is associated with a set of characteristic features that includes calcinosis, Raynaud's phenomenon, esophageal involvement, sclerodactyly, and telangiectasia. This report describes an unusual case of a patient who had spontaneous compartment syndrome of the hand. The patient's concomitant limited cutaneous systemic sclerosis may have played a role in this unusual occurrence. The diagnosis was based on the clinical picture, and the symptoms resolved after surgical decompression. Copyright 2015, SLACK Incorporated.

    Full Text Available According to the body-specificity hypothesis, people with different bodily characteristics should form correspondingly different mental representations, even in highly abstract conceptual domains. In a previous test of this proposal, right- and left-handers were found to associate positive ideas like intelligence, attractiveness, and honesty with their dominant side and negative ideas with their non-dominant side. The goal of the present study was to determine whether 'body-specific' associations of space and valence can be observed beyond the laboratory in spontaneous behavior, and whether these implicit associations have visible consequences.We analyzed speech and gesture (3012 spoken clauses, 1747 gestures from the final debates of the 2004 and 2008 US presidential elections, which involved two right-handers (Kerry, Bush and two left-handers (Obama, McCain. Blind, independent coding of speech and gesture allowed objective hypothesis testing. Right- and left-handed candidates showed contrasting associations between gesture and speech. In both of the left-handed candidates, left-hand gestures were associated more strongly with positive-valence clauses and right-hand gestures with negative-valence clauses; the opposite pattern was found in both right-handed candidates.Speakers associate positive messages more strongly with dominant hand gestures and negative messages with non-dominant hand gestures, revealing a hidden link between action and emotion. This pattern cannot be explained by conventions in language or culture, which associate 'good' with 'right' but not with 'left'; rather, results support and extend the body-specificity hypothesis. Furthermore, results suggest that the hand speakers use to gesture may have unexpected (and probably unintended communicative value, providing the listener with a subtle index of how the speaker feels about the content of the co-occurring speech.

    It is important to measure the functional capabilities of a prosthesis in order to make informed decisions when prescribing a limb. To measure the functional of a range of commercial single degree of freedom hands to act as baseline comparisons for the newer multi-axis hands. Form-board and self-timed tasks. Repeated measures with a single subject using a validated assessment tool. The test measured the function of three conventional, single axis, powered hands, controlled by five different myocontroller formats. One transcarpal device was also tested. When controlled by the same type of two channel myoelectric controllers (proportional voluntary opening, voluntary closing) the overall functional scores were similar for all similar types of hand, with a maximum score of 94 out of 100. The smaller transcarpel hand had a score of 84. Only when a more limited single channel three state controller was used was the score much lower (81). All of the hands were of a similar design and were set in a precision grip, but the precision grip did not achieve the highest individual grip score. Additionally, while the Southampton Hand Assessment Procedure (SHAP) score is dependent on the speed of execution of the task, the speed of the prosthesis did not have as great an impact on the score as the other variables. This study provides comparative data between similar designs of commercial hands. This will allow clinicians to be better informed when they prescribe a device for a user.

    The extant literature on manual laterality in non-human primates is inconclusive, plagued by inconsistent or contradictory findings and by disturbing methodological issues (e.g. uncontrolled influential factors, comparability issues). The present study examined hand preference and its flexibility in 15 red-capped mangabeys (C. t. torquatus) and 13 Campbell's monkeys (C. c. campbelli), two species that differ in their degree of arboreality. We investigated the influence of the spatial position of the object on hand preference for reaching. We considered spontaneous behaviour (reaching for food during daily feeding) and an experimental task: the QHP task. The QHP is a task that is used in humans. This is a simple reaching task that involves high spatial constraints on hand use. In our study, the subject had to reach for items that were placed on a semi-circle in front of it on five positions, including in the centre position, in the ipsilateral space and in the contralateral space. We assessed hand preference for reaching in front (baseline condition), and we examined how this preference changed when reaching in lateral positions. For reaching in front, about half of the subjects were lateralized and no group-level bias occurred, for both spontaneous and experimental conditions. When considering reaching in the lateral positions, we observed that the position of the object influenced hand use: individuals used the hand that was closest to the object. The results are discussed in relation to previous findings in humans and in non-human primates and regarding theories on handedness and flexibility of hand preference.

    The authors hypothesized that patients may not understand the forms of effective hand hygiene employed in the hospital environment. Multiple studies demonstrate the importance of hand hygiene in reducing healthcare-associated infections (HAIs). Extensive research about how to improve compliance has been conducted. Patients' perceptions of proper hand hygiene were evaluated when caregivers used soap and water, waterless hand cleaner, or a combination of these. No significant differences were observed, but many patients reported they did not notice whether their providers cleaned their hands. Educating patients and their caregivers about the protection afforded by proper, consistent hand hygiene practices is important. Engaging patients to monitor healthcare workers may increase compliance, reduce the spread of infection, and lead to better overall patient outcomes. This study revealed a need to investigate the effects of patient education on patient perceptions of hand hygiene. Results of this study appear to indicate a need to focus on patient education and the differences between soap and water versus alcohol-based hand sanitizers as part of proper hand hygiene. Researchers could be asking: "Why have patients not been engaged as members of the healthcare team who have the most to lose?"

    Intelligibility is a speaker's ability to convey a message to a listener. Including an assessment of intelligibility is essential in both research and clinical work relating to individuals with communication disorders due to speech impairment. Assessment of the intelligibility of spontaneous speech can be used as an overall indicator of the severity of a speech disorder. There is a lack of methods for measuring intelligibility on the basis of spontaneous speech. To investigate the validity and reliability of a method where listeners transcribe understandable words and an intelligibility score is calculated on the basis of the percentage of syllables perceived as understood. Spontaneous speech from ten children with speech-sound disorders (mean age = 6.0 years) and ten children with typical speech and language development (mean age = 5.9 years) was recorded and presented to 20 listeners. Results were compared between the two groups and correlation with percentage of consonants correct (PCC) was examined. The intelligibility scores obtained correlated with PCC in single words and differed significantly between the two groups, indicating high validity. Inter-judge reliability, analysed using intra-class correlation (ICC), was excellent in terms of the average measure for several listeners. The results suggest that this method can be recommended for assessing intelligibility, especially if the mean across several listeners is used. It could also be used in clinical settings when evaluating intelligibility over time, provided that the same listener makes the assessments. © 2013 Royal College of Speech and Language Therapists.

    Spontaneous instabilities can pose a significant challenge to verification of combustion stability, and characterizing its onset is an important avenue of improvement for stability assessments of liquid propellant rocket engines. Recurrence Quantification Analysis (RQA) is used here to explore nonlinear combustion dynamics that might give insight into instability. Multiple types of patterns representative of different dynamical states are identified within fluctuating chamber pressure data, and markers for impending instability are found. A class of metrics which describe these patterns is also calculated. RQA metrics are compared with and interpreted against another metric from nonlinear time series analysis, the Hurst exponent, to help better distinguish between stable and unstable operation.

    Full Text Available Ultra-weak photon emission in the visible range was measured on palm and dorsal side of left and right hand by means of a low noise photomultiplier system. To study the dynamics of this photon emission in a 24 h period photon emission was recorded in 2 h intervals in 5 experiments, utilizing strict protocols for dark adaptation and recording of subjects. Fluctuations in photon emission in the course of 24 h period were demonstrated for each anatomic location. Mean photon emission over the 24 h period differed both between subjects and hand locations. To detect a pattern in the fluctuations the mean value for each location of each subject in each experiment was utilized to calculate fluctuations during the course of 24 h for each anatomical location. The fluctuations in photon emission in the course of 24 h were more at dorsal sides than palm sides. The correlation between fluctuations in palm and dorsal side was not apparent. During the 24 h period a change in left-right symmetry occurred for the dorsal side but not for the palm of the hands. Photon emission at the left dorsal location was high at night, while the right dorsal side emitted most during the day. It is concluded that a daily rhythm in photon emission can be recorded from both the dorsal and palm sides of the hands.

  1. Using the intact hand for objective assessment of phantom hand-perception.

    After amputation, most patients experience a phenomenon known as a phantom limb (PL). A variety of PL experiences appear to be associated with neural plasticity within the CNS. However, due to the subjective nature of PL experiences, there was no definitive way to reliably assess PL experiences other than using patients' direct reports. Here, we were able to obtain patients' indirect responses to PL experiences, for a more objective evaluation. First, we conducted a study with normals and 17 non-PL patients experiencing pathological pain in one hand. We took digital photographs of their affected and unaffected hands, altered the sizes of the images digitally, and then asked each subject to choose the image that most closely matched the actual size of their own hands (from a series of images presented on a video screen). Subjective size perceptions of the hands were homologous, regardless of the pathological condition of one hand (pphantom hand. The intact hand-size perception was linearly correlated with phantom hand-size perception (weighted linear regression analysis: p<0.0001, R(2)=0.75, adjusted R(2)=0.73, F-value=50.1, degree of freedom=18). Thus, without requiring a subjective description about PL, the patients' evaluation of the intact hand-size precisely but indirectly indicated whether the PL was perceived to be telescoped (shrunken), normal or enlarged. This more objective evaluation of PL phenomena could become a key tool for disentangling the neural mechanisms involved. Crown Copyright 2009. Published by Elsevier Ltd. All rights reserved.

    Introduction Telehealth offers a solution to assist delivery of occupational therapy (OT) services for hand therapy in rural and remote locations. However, there is currently no evidence to validate this service model. The aim of this study was to examine the validity of clinical decisions made during hand therapy sessions conducted via telehealth compared to a traditional clinical model (TCM) assessment, and explore patient and clinician satisfaction. Methods Eighteen patients referred for hand therapy to a rural/remote hospital-based outpatient service were assessed simultaneously via telehealth and a TCM assessment. An allied health assistant supported data collection at the patient end. Hand function was assessed using a range of objective measures, subjective scales and patient reported information. Minimal level of percent exact agreement (PEA) between the telehealth OT (T-OT) and the TCM-OT was set at ≥80%. Results Level of agreement for all objective measures (dynamometer and pinch gauge reading, goniometer flexion and extension, circumference in millimetres) ranged between 82% and 100% PEA. High agreement (>80% PEA) was also obtained for judgements of scar and general limb function, exercise compliance, pain severity and sensitivity location, activities of daily living and global ratings of change (GROC) scores. There was 100% PEA for overall recommendations. Minimal technical issues were experienced. Patient and clinician satisfaction was high. Discussion Clinical decisions made via telehealth were comparable to the TCM and consumers were satisfied with telehealth as a service option. Telehealth offers the potential to improve access to hand therapy services for rural and remote patients.

    Liquid rocket engine combustion stability assessments are traditionally broken into three categories: dynamic stability, spontaneous stability, and rough combustion. This work focuses on comparing the spontaneous stability and rough combustion assessments for several liquid engine programs. The techniques used are those developed at Marshall Space Flight Center (MSFC) for the J-2X Workhorse Gas Generator program. Stability assessment data from the Integrated Powerhead Demonstrator (IPD), FASTRAC, and Common Extensible Cryogenic Engine (CECE) programs are compared against previously processed J-2X Gas Generator data. Prior metrics for spontaneous stability assessments are updated based on the compilation of all data sets.

    Although various hand assist devices have been commercialized for people with paralysis, they are somewhat limited in terms of tool fixation and device attachment method. Hand exoskeleton robots allow users to grasp a wider range of tools but are heavy, complicated, and bulky owing to the presence of numerous actuators and controllers. The GRIPIT hand assist device overcomes the limitations of both conventional devices and exoskeleton robots by providing improved tool fixation and device attachment in a lightweight and compact device. GRIPIT has been designed to assist tripod grasp for people with spinal cord injury because this grasp posture is frequently used in school and offices for such activities as writing and grasping small objects. The main development objective of GRIPIT is to assist users to grasp tools with their own hand using a lightweight, compact assistive device that is manually operated via a single wire. GRIPIT consists of only a glove, a wire, and a small structure that maintains tendon tension to permit a stable grasp. The tendon routing points are designed to apply force to the thumb, index finger, and middle finger to form a tripod grasp. A tension-maintenance structure sustains the grasp posture with appropriate tension. Following device development, four people with spinal cord injury were recruited to verify the writing performance of GRIPIT compared to the performance of a conventional penholder and handwriting. Writing was chosen as the assessment task because it requires a tripod grasp, which is one of the main performance objectives of GRIPIT. New assessment, which includes six different writing tasks, was devised to measure writing ability from various viewpoints including both qualitative and quantitative methods, while most conventional assessments include only qualitative methods or simple time measuring assessments.

    Often in Parkinson's disease (PD) motor-related problems overshadow latent non-motor deficits as it is difficult to dissociate one from the other with commonly used observational inventories. Here we ask if the variability patterns of hand speed and acceleration would be revealing of deficits in spatial-orientation related decisions as patients performed a familiar reach-to-grasp task. To this end we use spatial-orientation priming which normally facilitates motor-program selection and asked whether in PD spatial-orientation priming helps or hinders performance. To dissociate spatial-orientation- and motor-related deficits participants performed two versions of the task. The biomechanical version (DEFAULT) required the same postural- and hand-paths as the orientation-priming version (primed-UP). Any differences in the patients here could not be due to motor issues as the tasks were biomechanically identical. The other priming version (primed-DOWN) however required additional spatial and postural processing. We assessed in all three cases both the forward segment deliberately aimed towards the spatial-target and the retracting segment, spontaneously bringing the hand to rest without an instructed goal. We found that forward and retracting segments belonged in two different statistical classes according to the fluctuations of speed and acceleration maxima. Further inspection revealed conservation of the forward (voluntary) control of speed but in PD a discontinuity of this control emerged during the uninstructed retractions which was absent in NC. Two PD groups self-emerged: one group in which priming always affected the retractions and the other in which only the more challenging primed-DOWN condition was affected. These PD-groups self-formed according to the speed variability patterns, which systematically changed along a gradient that depended on the priming, thus dissociating motor from spatial-orientation issues. Priming did not facilitate the motor task in PD

    Considerable interest lies in the ability to characterize the onset of spontaneous instabilities within liquid propellant rocket engine (LPRE) combustion devices. Linear techniques, such as fast Fourier transforms, various correlation parameters, and critical damping parameters, have been used at great length for over fifty years. Recently, nonlinear time series methods have been applied to deduce information pertaining to instability incipiency hidden in seemingly stochastic combustion noise. A technique commonly used in biological sciences known as the Multifractal Detrended Fluctuation Analysis has been extended to the combustion dynamics field, and is introduced here as a data analysis approach complementary to linear ones. Advancing, a modified technique is leveraged to extract artifacts of impending combustion instability that present themselves a priori growth to limit cycle amplitudes. Analysis is demonstrated on data from J-2X gas generator testing during which a distinct spontaneous instability was observed. Comparisons are made to previous work wherein the data were characterized using linear approaches. Verification of the technique is performed by examining idealized signals and comparing two separate, independently developed tools.

    To determine whether bioimpedance spectroscopy was suitable for detection of hand lymphoedema. The hands of 50 participants without a history of lymphoedema were measured with perometry and bioimpedance spectroscopy after positioning two ways for three minutes: (a) both hands rested at heart height and (b) the dominant hand at heart height and the non-dominant hand at head height. In addition, 10 women with secondary hand lymphoedema were also measured. Impedance and volume measurements were found to be strongly related (dominant hand r = -0.794). Both measurements were reliable (ICC2,1 = 0.900-0.967 and 0.988-0.996, respectively). Impedance was more sensitive to small changes in hand volume due to the postural change (position × device interaction: F = 23.9, P < 0.001). Finally, impedance measurements had better discrimination of women with lymphoedema than volume measurements. Bioimpedance spectroscopy is a promising tool for the detection of secondary hand lymphoedema.

Watching a rubber hand being stroked while one's unseen hand is stroked synchronously can lead to a sense of ownership over the rubber hand, a shift in perceived position of the real hand, and a limb-specific drop in stimulated hand temperature. We aimed to assess the RHI in schizophrenia using quantifiable measures: proprioceptive drift and stimulation-dependent changes in hand temperature.The RHI was elicited in 24 schizophrenia patients and 21 matched controls by placing their unseen hand adjacent to a visible rubber hand and brushing real and rubber hands synchronously or asynchronously. Perceived finger location was measured before and after stimulation. Hand temperature was taken before and during stimulation. Subjective strength of the illusion was assessed by a questionnaire.Across groups, the RHI was stronger during synchronous stimulation, indicated by self-report and proprioceptive drift. Patients reported a stronger RHI than controls. Self-reported strength of RHI was associated with schizotypy in controls Proprioceptive drift was larger in patients, but only following synchronous stimulation. Further, we observed stimulation-dependent changes in skin temperature. During right hand stimulation, temperature dropped in the stimulated hand and rose in the unstimulated hand. Interestingly, induction of RHI led to an out-of-body experience in one patient, linking body disownership and psychotic experiences.The RHI is quantitatively and qualitatively stronger in schizophrenia. These findings suggest that patients have a more flexible body representation and weakened sense of self, and potentially indicate abnormalities in temporo-parietal networks implicated in body ownership. Further, results suggest that these body ownership disturbances might be at the heart of a subset of

    This work presents techniques for liquid rocket engine combustion stability assessments with respect to spontaneous stability and rough combustion. Techniques covering empirical parameter extraction, which were established in prior works, are applied for three additional programs: the F-1 Gas Generator (F1GG) component test program, the RS-84 preburner component test program, and the Marshall Integrated Test Rig (MITR) program. Stability assessment parameters from these programs are compared against prior established spontaneous stability metrics and updates are identified. Also, a procedure for comparing measured with predicted mode shapes is presented, based on an extension of the Modal Assurance Criterion (MAC).

    Hand hygiene is probably the most effective tool of nosocomial infection prevention, however, proper feedback and control is needed to develop the individual hand hygiene practice. Assessing the efficiency of modern education tools, and digital demonstration and verification equipment during their wide-range deployment. 1269 healthcare workers took part in a training organized by our team. The training included the assessment of the participants' hand hygiene technique to identify the most often missed areas. The hand hygiene technique was examined by a digital device. 33% of the participants disinfected their hands incorrectly. The most often missed sites are the fingertips (33% on the left hand, 37% on the right hand) and the thumbs (42% on the left hand, 32% on the right hand). The feedback has a fundamental role in the development of the hand hygiene technique. With the usage of electronic devices feedback can be provided efficiently and simply.

    Full Text Available Introduction & Objective: Nowadays, some studies indicate the adverse effects of exposure to chemicals, especially organic solvents on the reproductive system of females. This study aimed to assess the relationship between spontaneous abortion with occupational exposure to organic solvents in pharmaceutical industry. Materials & Methods: This is a cross-sectional and descriptive-analytical study which was carried out in 2010 in one of the pharmaceutical factories located in the suburbs of Tehran. During the study, married women who were working in the factory laboratory units and were exposed to mixed organic solvents were compared with married women who were working in the packing units of the factory without occupational exposure to organic solvents. Frequency of spontaneous abortion and duration of pregnancy were assessed in both two groups. Collected data were analyzed with the SPSS software using t-test, logistic regression, and chi-square test. Results: In the present study, the frequency of spontaneous abortion in employees with exposure to organic solvents mixture was 10.7%. This study showed that even after adjustment for confounding factors, there was a significant correlation between spontaneous abortion and occupational exposure to organic solvents mixture and this correlation increased with increasing levels of exposure to organic solvents. Moreover, a significant correlation was observed between occupational exposure to mixed organic solvents and waiting time to become pregnant (TTP. Furthermore, this study showed that even after adjustment for confounding variables, shift workers were significantly more affected by spontaneous abortion compared to daytime workers (P < 0.001. Conclusion: According to the results of this study, since there is probability of spontaneous abortion resulting from occupational exposure to various chemicals including organic solvents, review of the status of occupational exposure of workers can be helpful

    The hand engages with the environment through the grasp, stabilisation, manipulation and release of objects during everyday tasks, activities and routines. Upper motor neuron syndrome following acquired brain injury may negatively impact hand function, reducing strength, range of motion and motor control. It is important for clinicians to reliably measure such impacts, particularly for the impact of intervention and to monitor change in performance over time. Therefore, the aim of this study was to investigate the test-retest reliability and construct validity of Dynamic Computerised pinch Dynamometry for measuring fine hand motor performance following acquired brain injury. The Dynamic Computerised pinch Dynamometry protocol was completed by 36 community dwelling adults and 27 healthy adults using a simulated pinch and release task in lateral and pincer grip positions. Measurements were conducted over two testing occasions approximately five weeks apart. Dynamic Computerised pinch Dynamometry output was evaluated to determine the test-retest reliability and construct validity of the measure. Test-retest reliability scores using Kendall coefficient of concordance ranged from W = 0.61-0.94. Dynamic Computerised pinch Dynamometry discriminated between participants with and without acquired brain injury (z = 4.97-6.50, P hand of participants with acquired brain injury (z = 3.37-5.22, P hand of participants with acquired brain injury. © 2014 Occupational Therapy Australia.

    Result: Results of the present study indicated that in all measured situations, exposure to hand arm vibration was higher than the standard limit suggested by Iranian occupational health committee and there was risk of vibration-induced disorders. The maximum exposure to vibration is in plowing ground. Exposure to hand arm vibration in three modes of plowing, transmission and natural, were respectively 16.95, 14.16 and 8.65 meters per second squared. Additionally, in all situations, vibration exposure was highest in the X-axis in comparison with Z- and Y-axes. .Conclusion: This study emphasizes on the need to provide intervention and controlling and managing strategies in order to eliminate or reduce vibration transmitted from tiller to operators hand and arm and also prevent to serious problems including neurovascular disorders, discomfort and white finger syndrome. Meanwhile, more studies are necessary to identify the sources of vibration on different models of tiller.

    This paper presents the design of a hand exoskeleton intended to enable or facilitate bimanual activities of daily living (ADLs) for individuals with chronic upper extremity hemiparesis resulting from stroke. The paper describes design of the battery-powered, self-contained exoskeleton and presents the results of initial testing with a single subject with hemiparesis from stroke. Specifically, an experiment was conducted requiring the subject to repeatedly remove the lid from a water bottle both with and without the hand exoskeleton. The relative times required to remove the lid from the bottles was considerably lower when using the exoskeleton. Specifically, the average amount of time required to grasp the bottle with the paretic hand without the exoskeleton was 25.9 s, with a standard deviation of 33.5 s, while the corresponding average amount of time required to grasp the bottle with the exoskeleton was 5.1 s, with a standard deviation of 1.9 s. Thus, the task time involving the paretic hand was reduced by a factor of five, while the standard deviation was reduced by a factor of 16.

    Sensations and thoughts have been described as potentially related to self-awareness. We therefore asked whether sensations that arise in the absence of external triggers, i.e., spontaneous sensations (SPS), which were shown to relate to interoception and perception of the self, vary as a function of the individual propensity to generate spontaneous thoughts, i.e., mind-wandering. The Mind Wandering Questionnaire (MWQ) was used as a specific tool to assess the frequency and propensity to mind-wander several weeks before completing an SPS task. Correlational analyses between the MWQ score and SPS showed that greater propensity to mind-wander coincided with widespread perception of SPS, while lesser propensity to mind-wander coincided with more spatially restricted perception of SPS. The results are interpreted in light of the role of spontaneous thoughts and sensations in self-awareness. The potential psychological processes and the way they might regulate the relation between mind-wandering and the perception of SPS are discussed. Copyright © 2017 Elsevier Inc. All rights reserved.

    In this study we compared trabecular bone mineral density (BMD) with textural parameters (cooccurence matrices features) extracted from trabecular bone structures in radiographic images of the hand. Our data consists of 12 cadaver hands radiographed and digitized. After application of a specific preprocessing step on all images, the textural parameters were calculated within 4 regions of interest defined within the metacarpal and proximal phalanges on trabecular bone. The results show that using a combination of textural parameters calculated at different directions within the ROI could increase significantly the correlation with BMD. Some further research will validate this finding on a larger set of data. This work is intended to be applicable in the study of bone fractures associated with osteoporosis, and could be of great benefit to a large segment of the population at risk.

    Rheumatoid arthritis (RA) is a chronic inflammatory disease leading to severe joint damage, particularly in the wrist, fingers and toes. To prevent irreversible joint damage, it is crucial that RA is treated in an early stage. The effect of treatment methods can differ per patient. Therefore it is important that disease activity is carefully monitored, such that a treatment can be altered if necessary. In order to visualize joint damage, radiographs of hands and feet are often used. In the pa...

    The aim of this study was to develop a descriptive and evaluative assessment of upper limb function for infants aged 3 to 12 months and to investigate its internal scale validity for use with infants at risk of unilateral cerebral palsy. The concepts of the test items and scoring criteria were developed. Internal scale validity and aspects of reliability were investigated on the basis of 156 assessments of infants at 3 to 12 months corrected age (mean 7.2mo, SD 2.5) with signs of asymmetric hand use. Rasch measurement model analysis and non-parametric statistics were used. The new test, the Hand Assessment for Infants (HAI), consists of 12 unimanual and five bimanual items, each scored on a 3-point rating scale. It demonstrated a unidimensional construct and good fit to the Rasch model requirements. The excellent person reliability enabled person separation to six significant ability strata. The HAI produced an interval-level measure of bilateral hand use as well as unimanual scores of each hand, allowing a quantification of possible asymmetry expressed as an asymmetry index. The HAI can be considered a valid assessment tool for measuring bilateral hand use and quantifying side difference between hands among infants at risk of developing unilateral cerebral palsy. The Hand Assessment for Infants (HAI) measures the use of both hands and quantifies a possible asymmetry of hand use. HAI is valid for infants at 3 to 12 months corrected age at risk of unilateral cerebral palsy. © 2017 Mac Keith Press.

    Full Text Available Background: The purpose of this study is to evaluate the number of reviews and scores for active members of the American Society for Surgery of the Hand (ASSH in popular physician rating websites (Healthgrades.com and Vitals.com. Methods: A total of 433 ASSH active members were searched in two popular rating websites for a total of 866 web searches. Demographic data, overall and subcategory scores, number of reviews, and wait times were scored from each member’s webpage. Results: The average number of reviews per surgeon on Healthgrades.com and Vitals.com were 13.8 (range 1-108 and 9.4 (range 0-148, respectively. The average overall score for physicians was 8.1 out of 10 points. For both websites, the vast majority (80-90% of active members of the ASSH had 20 or less reviews. Multivariate data analysis revealed no statistical differences in overall score by region (P=0.24 or gender (P=0.38. Increasing physician age negatively correlated with overall score (P=0.01. Wait time was not associated with a negative score (P=0.38. Conclusion: Active members of the ASSH received generally positive reviews. The average number of reviews for active members of the ASSH was exceedingly small, bringing into question the legitimacy and validity of these scores. This is especially important when taking into consideration the increasing popularity of these websites, and the reliance of patients on them to obtain physician information. The clinical implication of this study is that physicians have a vested interest in the legitimacy of the data provided by these websites and other physician rating outlets.

  9. Occupational therapy-based and evidence-supported recommendations for assessment and exercises in hand osteoarthritis.

    2011-12-01

    The aims of this study were to develop recommendations for occupational therapy assessment and design of hand exercise programmes in patients with hand osteoarthritis. An expert group followed a Delphi procedure to reach consensus for up to 10 recommendations for assessment and exercises, respectively. Thereafter, an evidence-based approach was used to identify and appraise research evidence supporting each recommendation, before the recommendations were validated by the expert group. The process resulted in 10 recommendations for assessment and eight for design of exercise programmes. The literature search revealed that there is a paucity of clinical trials to guide recommendations for hand osteoarthritis, and the evidence for the majority of the recommendations was based on expert opinions. Also, even if a systematic review demonstrates some evidence for the efficacy of strength training exercises in hand OA, the evidence for any specific exercise is limited to expert opinions. A first set of recommendations for assessment and exercise in hand osteoarthritis has been developed. For many of the recommendations there is a paucity of research evidence. High-quality studies are therefore needed to establish a high level of evidence concerning functional assessment and the effect of hand exercises in hand osteoarthritis.

    2015-01-01

    Full Text Available Preterm birth is associated with increased risks of neurological and motor impairments such as cerebral palsy. The risks are highest in those born at the lowest gestations. Early identification of those most at risk is challenging meaning that a critical window of opportunity to improve outcomes through therapy-based interventions may be missed. Clinically, the assessment of spontaneous general movements is an important tool which can be used for the prediction of movement impairments in high risk infants.Movement recognition aims to capture and analyze relevant limb movements through computerized approaches focusing on continuous, objective, and quantitative assessment. Different methods of recording and analyzing infant movements have recently been explored in high risk infants. These range from camera-based solutions to body-worn miniaturized movement sensors used to record continuous time-series data that represent the dynamics of limb movements. Various machine learning methods have been developed and applied to the analysis of the recorded movement data. This analysis has focused on the detection and classification of atypical spontaneous general movements. This paper aims to identify recent translational studies using movement recognition technology as a method of assessing movement in high risk infants. The application of this technology within pediatric practice represents a growing area of inter-disciplinary collaboration which may lead to a greater understanding of the development of the nervous system in infants at high risk of motor impairment.

    Directory of Open Access Journals (Sweden)

    Christine Kuehner

    Full Text Available People's minds frequently wander towards self-generated thoughts, which are unrelated to external stimuli or demands. These phenomena, referred to as "spontaneous thought" (ST and "mind wandering" (MW, have previously been linked with both costs and benefits. Current assessments of ST and MW have predominantly been conducted in the laboratory, whereas studies on the ecological validity of such lab-related constructs and their interrelations are rare. The current study examined the stability of ST dimensions assessed in the lab and their predictive value with respect to MW, repetitive negative thought (uncontrollable rumination, RUM, and affect in daily life. Forty-three university students were assessed with the Amsterdam Resting State Questionnaire (2nd version to assess ten ST dimensions during the resting state in two laboratory sessions, which were separated by five days of electronic ambulatory assessment (AA. During AA, individuals indicated the intensity of MW and RUM, as well as of positive and negative affect in daily life ten times a day. ST dimensions measured in the lab were moderately stable across one week. Five out of ten ST lab dimensions were predicted by mental health-related symptoms or by dispositional cognitive traits. Hierarchical linear models revealed that a number of ST lab dimensions predicted cognitive and affective states in daily life. Mediation analyses showed that RUM, but not MW per se, accounted for the relationship between specific ST lab dimensions and mood in daily life. By using a simple resting state task, we could demonstrate that a number of lab dimensions of spontaneous thought are moderately stable, are predicted by mental health symptoms and cognitive traits, and show plausible associations with categories of self-generated thought and mood in daily life.

    Sensory perception is crucial for motor learning and the control of fine manipulations. However, therapy after stroke still strongly focuses on the training of motor skills. Sensory assessments are often left out or provide only very subjective data from poorly controlled stimuli. This paper presents a vibration detection/localization test with the Robotic Sensory Trainer, a device that focuses entirely on the assessment and training of sensory function of the hand, with the aim of gaining insights into the prevalence and severity of sensory deficits after stroke, and to provide semiobjective data on absolute and difference perception thresholds in patients. An initial feasibility study investigated localization performance and reaction time during the discrimination of vibration stimuli presented in four locations on the dominant and nondominant hands of 13 healthy volunteers. High correct detection rates were observed (mean ± SD of 99.6% ± 0.6%), touch screen PC Robotic Sensory Trainer which were found to be significantly different between stimulus locations on the dominant hand. Average correct detection rates were not statistically different between dominant and nondominant hand. These data will serve as baseline for future measurements on elderly and stroke subjects, and suggest that data from the nonimpaired hand could be used to identify and assess sensory deficits in the affected hand of stroke patients.

    Descriptive survey. This study specifically explored the use of occupation-based assessments and intervention in the hand therapy setting, but also more generally, current practice trends about all assessments being utilized in this setting, frequency of their use, and therapists' perceptions about them. An online survey was distributed via email to members of the American Society of Hand Therapists (ASHT). The survey consisted of ten questions and was administered via Survey Monkey. Responses were received from 22% of those surveyed. A descriptive analysis was completed of the results and indicated that over half use occupation-based assessments on a daily basis; most are related to ADL function and used for the development of goals. The primary reason for not utilizing occupation-based assessments is time limitation. Seventy-nine percent believe these measures are important for the services provided in the hand therapy setting. Occupation-based assessments and intervention are not utilized as much as therapists would like in the hand therapy setting, primarily due to time constraints. While not formally assessed, the majority of those who responded indicated that they do address occupation in their assessments and interventions. Not applicable. Copyright © 2015 Hanley & Belfus.

    Udaipur, Banswara and Dungarpur districts of southern Rajasthan (India) have dominance of tribal population. In these districts besides other water resources, hand pumps are catering the need for drinking water. The present study was undertaken to assess the level of chemical and bacteriological status for comparing the water quality with the prevailing standards. 18 hand pumps were studied for selected water quality parameters such as, pH, hardness, chloride, fluoride, NO3 -N, EC, orthophosphate, TDS, TSS, BOD, total coliforms and faecal coliforms, following the standard methods. The data on chemical parameters revealed that in all 18 hand pumps the water quality was within the permissible level of WHO. However, in eight hand pumps the faecal coliforms were higher (2-6 MPN/100 mL) than the permissible limit which confirm organic contamination in these drinking water resources. On the basis of this study, suitable remedial measures for protection of water quality have been suggested.

    To evaluate the antimicrobial efficacy of four different hand sanitizers against Staphylococcus aureus , Staphylococcus epidermidis , Pseudomonas aeruginosa , Escherichia coli , and Enterococcus faecalis as well as to assess and compare the antimicrobial effectiveness among four different hand sanitizers. The present study is an in vitro study to evaluate antimicrobial efficacy of Dettol, Lifebuoy, PureHands, and Sterillium hand sanitizers against clinical isolates of the aforementioned test organisms. The well variant of agar disk diffusion test using Mueller-Hinton agar was used for evaluating the antimicrobial efficacy of hand sanitizers. McFarland 0.5 turbidity standard was taken as reference to adjust the turbidity of bacterial suspensions. Fifty microliters of the hand sanitizer was introduced into each of the 4 wells while the 5 th well incorporated with sterile water served as a control. This was done for all the test organisms and plates were incubated in an incubator for 24 h at 37΀C. After incubation, antimicrobial effectiveness was determined using digital caliper (mm) by measuring the zone of inhibition. The mean diameters of zones of inhibition (in mm) observed in Group A (Sterillium), Group B (PureHands), Group C (Lifebuoy), and Group D (Dettol) were 22 ± 6, 7.5 ± 0.5, 9.5 ± 1.5, and 8 ± 1, respectively. Maximum inhibition was found with Group A against all the tested organisms. Data were statistically analyzed using analysis of variance, followed by post hoc test for group-wise comparisons. The difference in the values of different sanitizers was statistically significant at P < 0.001. Sterillium was the most effective hand sanitizer to maintain the hand hygiene.

    The aim of this study was to examine the effect of the side of brain lesion on the ipsilesional hand function of stroke survivors. Twenty-four chronic stroke survivors, equally allocated in 2 groups according to the side of brain lesion (right or left), and 12 sex- and age-matched healthy controls performed the Jebsen-Taylor Hand Function Test (JTHFT), the Nine-Hole Peg Test (9HPT), the maximum power grip strength (PwGS max ) test, and the maximum pinch grip strength (PnGS max ) test. Only the ipsilesional hand of the stroke survivors and both hands (left and right) of the controls were assessed. PwGS max and PnGS max were similar among all tested groups. Performances in JTHFT and 9HPT were affected by the brain injury. Individuals with left brain damage showed better performance in 9HPT than individuals with right brain damage, but performance in JTHFT was similar. Individuals after a brain injury have the capacity to produce maximum strength preserved when using their ipsilesional hand. However, the dexterity of their hands and digits is affected, in particular for stroke individuals with right brain lesion. Copyright © 2017 National Stroke Association. Published by Elsevier Inc.

    Workers exposed to hand-arm vibration are at risk of developing the neurological abnormalities of hand-arm vibration syndrome (HAVS). The Stockholm classification of the neurological component of HAVS is based on history and physical examination. There is a need to determine the association between neurological tests and the Stockholm scale. The main objective of this study was to compare the Stockholm neurological scale and the results of current perception threshold (CPT) tests and nerve conduction studies (NCS). Detailed physical examinations were done on 162 subjects referred for HAVS assessment at a specialist occupational health clinic. All subjects had NCS and measurement of CPT. The Stockholm neurological classification was carried out blinded to the results of these neurological tests and compared to the test results. The nerve conduction results indicated that median and ulnar neuropathies proximal to the hand are common in workers being assessed for HAVS. Digital sensory neuropathy was found in only one worker. Neither the nerve conduction results nor the current perception results had a strong association with the Stockholm neurological scale. Exposure to vibration in total hours was the main variable associated with the Stockholm neurological scale [right hand: OR 1.30, 95% CI (1.10-1.54); left hand: OR 1.18, 95% CI (1.0-1.39)]. Workers being assessed for HAVS should have nerve conduction testing to detect neuropathies proximal to the hand. Quantitative sensory tests such as current perception measurement are insufficient for diagnostic purposes but may have a role in screening workers exposed to vibration.

    Chronic spontaneous urticaria (CSU) is a common dermatological condition defined by the sudden occurrence of daily wheals and pruritus for at least six weeks. Multifactorial origin is suggested such as oxidative stress. This latter may play a double role as a trigger and remnant agent. The first aim of this study is to investigate antioxidant status, inflammatory proteins, hematologic counts and clinical assessment in CSU patients. The second aim is to evaluate the effect of a first-line treatment: desloratadine 5 mg/d on these different parameters. This study enrolled 30 CSU patients and same number of controls. We assessed the urticaria activity score (UAS), total antioxidant status (TAS), glutathione S-transferase (GST), superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT), albumin, alpha1, alpha2, beta1 beta2, gamma globulins, c-reactive protein (CRP) and hematologic numeration. At baseline alpha1, alpha2, beta1, beta2, gamma globulins, CRP, SOD activity, leukocytes and basophils were significantly higher in patients versus controls (p < 0.05). TAS, GST, CAT, GPx and albumin were significantly low in patients versus controls (p < 0.05). After treatment, TAS, GST and GPx were significantly increased in patients versus patients before treatment (p < 0.001). SOD, alpha1, alpha2, beta1, beta2, gamma globulins, CRP, albumin, leukocytes and basophils were significantly decreased after treatment versus before treatment (p < 0.05). A significant correlation between CRP and UAS (r = 0.3; p = 0.011) was noted. UAS assessment revealed the efficacy of 30 d-antihistaminic treatment. Desloratadine exerted anti-inflammatory and antioxidant effects on CSU patients revealed by CRP. Patients' remission was synergistic to CRP attenuation emphasizing CRP relevance for CSU clinical assessment.

    Our aim was to evaluate the validity of the cervical vertebra maturation (CVM) method as an indicator of skeletal age during the circumpubertal period by correlating the CVM method with the hand-wrist maturation (HWM) method in an attempt to eliminate the need for hand-wrist radiographs for maturity assessment. Hand-wrist and lateral cephalometric radiographs of 400 Chinese were randomly selected. The age for girls was between 10 years and 15 years and for boys it was between 12 years and 17 years, so that they were within the circumpubertal period. The CVM was assessed by a method developed by Baccetti and co-workers, whereas hand-wrist maturation was assessed by Fishman's method. The CVM was significantly correlated with HWM skeletal age. (Spearman's r boys = 0.9206, girls = 0.9363). All the patients in cervical vertebra stage 3 (CVS3) of CVM corresponded to skeletal maturation indicator 2 (SMI2) or SMI3 stages of HWM (around the peak of the growth spurt). The method error was insignificant. CVM is a valid indicator of skeletal growth during the circumpubertal period. This work will provide dental practitioners with information on jaw growth modification therapy. (orig.)

    The frequently low quality of submitted spontaneous reports is of an increasing concern; to our knowledge, no validated instrument exists for assessing case reports' quality comprehensively enough. This work was conducted to develop such a quality instrument for assessing the spontaneous reports of adverse drug reaction (ADR)/adverse drug event (ADE) in China. Initial evaluation indicators were generated using systematic and literature data analysis. Final indicators and their weights were identified using Delphi method. The final quality instrument was developed by adopting the synthetic scoring method. A consensus was reached after four rounds of Delphi survey. The developed quality instrument consisted of 6 first-rank indicators, 18 second-rank indicators, and 115 third-rank indicators, and each rank indicator has been weighted. It evaluates the quality of spontaneous reports of ADR/ADE comprehensively and quantitatively on six parameters: authenticity, duplication, regulatory, completeness, vigilance level, and reporting time frame. The developed instrument was tested with good reliability and validity, which can be used to comprehensively and quantitatively assess the submitted spontaneous reports of ADR/ADE in China.

    Respiratory system modelling can aid clinical decision making during mechanical ventilation (MV) in intensive care. However, spontaneous breathing (SB) efforts can produce entrained "M-wave" airway pressure waveforms that inhibit identification of accurate values for respiratory system elastance and airway resistance. A pressure wave reconstruction method is proposed to accurately identify respiratory mechanics, assess the level of SB effort, and quantify the incidence of SB effort without uncommon measuring devices or interruption to care. Data from 275 breaths aggregated from all mechanically ventilated patients at Christchurch Hospital were used in this study. The breath specific respiratory elastance is calculated using a time-varying elastance model. A pressure reconstruction method is proposed to reconstruct pressure waves identified as being affected by SB effort. The area under the curve of the time-varying respiratory elastance (AUC Edrs) are calculated and compared, where unreconstructed waves yield lower AUC Edrs. The difference between the reconstructed and unreconstructed pressure is denoted as a surrogate measure of SB effort. The pressure reconstruction method yielded a median AUC Edrs of 19.21 [IQR: 16.30-22.47]cmH2Os/l. In contrast, the median AUC Edrs for unreconstructed M-wave data was 20.41 [IQR: 16.68-22.81]cmH2Os/l. The pressure reconstruction method had the least variability in AUC Edrs assessed by the robust coefficient of variation (RCV)=0.04 versus 0.05 for unreconstructed data. Each patient exhibited different levels of SB effort, independent from MV setting, indicating the need for non-invasive, real time assessment of SB effort. A simple reconstruction method enables more consistent real-time estimation of the true, underlying respiratory system mechanics of a SB patient and provides the surrogate of SB effort, which may be clinically useful for clinicians in determining optimal ventilator settings to improve patient care.

    Scoping review. Sensorimotor deficits can impair function and may be present in individuals with common upper extremity conditions. To provide clinicians with an understanding of the usefulness of the assessments to evaluate sensorimotor function and the interventions reported in the literature to effect positive change in our patients with sensorimotor deficits affecting the hand and wrist. A systematic search produced seventeen studies involving sensorimotor retraining and assessment of sensorimotor performance for the upper extremity. Sensorimotor interventions and assessments found in the literature vary in regards to their effectiveness in restoring sensorimotor function in subjects with a number of conditions that affect hand and wrist function. There is a potential value of sensorimotor interventions for individuals with specific upper extremity conditions. There is a need for further studies to improve treatment of sensorimotor deficits and understanding of sensorimotor interventions. Copyright © 2014 Hanley & Belfus. Published by Elsevier Inc.

    The forensic anthropologist is responsible for contributing to the identification of an unknown by constructing a biological profile from their skeletal remains. Towards achieving this goal, anthropologists can apply population and temporally specific standards with known error margins to morphometric data collected from a decedent. Recent research relating to the formulation of sex estimation standards has focussed on the assessment of bones other than the traditionally favoured pelvis and cranium, such as long bones of the appendicular skeleton. In particular, sex estimation standards based on morphometric data from metacarpals and phalanges have reported classification accuracy rates of 80% (and above) based on a narrow range of populations. The purpose of this study is to provide population-specific hand bone sex-estimation standards for a contemporary Western Australian population. The present study examines digital right hand radiographs of 300 adults of known age, equally represented by sex. A total of 40 measurements were taken in each hand (metacarpals and proximal phalanges); the measurements were then analysed using univariate statistics and cross-validated direct and stepwise discriminant function analysis. All hand bone measurements were significantly sexually dimorphic, with a tendency for the width measurements to express a higher degree of dimorphism than the length measurements. A maximum cross-validated classification accuracy of 91% was achieved with a sex bias of -6%. The standards presented here can be used in future forensic investigations that require sex estimation of hand bones in a Western Australian population. Copyright © 2014 Elsevier Ireland Ltd.

    Full Text Available The Delft Hand 2 (DH-2 is an underactuated robot hand meant for industrial applications, having six degrees of freedom (DoF, one actuator (DoA and no sensors. It was designed to provide a cheap and robust hand to grasp a large range of objects without damaging them. The goal of this paper is to assess the design and performance of the DH-2, demonstrating how the design was optimized for its intended application area and how the hand was simplified to make it commercially attractive. Performance tests show that the DH-2 has a payload of 2 kg for an object range of 60 to 120 mm, it can close or open within 0.5 s, and it only uses open-loop control by means of the input voltage of the motor. The results demonstrate that the industrial need of a simple, cheap and effective robotic hand can be achieved with the principle of underactuation and the use of conventional components.

    The objectives of this pilot study were to assess the potential use of 3D videography for analyzing the motion of the body center of mass (COM) in newborns and to determine differences in spontaneous movements between preterm and full-term infants. The group comprised 10 preterm newborns (gestational age at birth between 26 and 37 weeks; birth weight 800 to 2960 g; gestational age at the time of examination 34 to 39 weeks) and 10 full-term infants (gestational week 38 to 41; birth weight 2810 to 4360 g). To determine the range of motion of the COM, 3D videography was used (2 cameras, 25 Hz). When recording their movements, the infants were in the supine position, calm and awake. The recordings were processed using the APAS software. Selected points on the body were marked to obtain data for calculating the basic parameters of COM trajectories. The range of motion of the COM in both craniocaudal and anteroposterior directions was significantly greater in premature infants (P preterm babies. This was also valid for the velocity of motion of the COM in the craniocaudal direction (P preterm infants. Basic kinematic characteristics of the motion of the COM (range, variability, velocity) are greater in preterm infants.

    The application of gene mapping methods to uncover the genetic basis of hypertension in the inbred spontaneously hypertensive rat (SHR) began over 25 yr ago. This animal provides a useful model of genetic high blood pressure, and some of its features are described. In particular, it appears to be a polygenic model of disease, and polygenes participate in human hypertension genetic risk. The SHR hypertension alleles were fixed rapidly by selective breeding in just a few generations and so are presumably common genetic variants present in the outbred Wistar strain from which SHR was created. This review provides a background to the origins and genesis of this rat line. It considers its usefulness as a model organism for a common cardiovascular disease. The progress and obstacles facing mapping are considered in depth, as are the emergence and application of other genome-wide genetic discovery approaches that have been applied to investigate this model. Candidate genes, their identification, and the evidence to support their potential role in blood pressure elevation are considered. The review assesses the progress that has arisen from this work has been limited. Consideration is given to some of the factors that have impeded progress, and prospects for advancing understanding of the genetic basis of hypertension in this model are discussed.

    Overall, the efficacy of the newer antidepressants: serotonin selective reuptake inhibitors (SSRI), selective serotonin/norepinephrine reuptake inhibitor (SNRI), noradrenergic and specific serotonergic antidepressant (NaSSA) and tianeptine is similar to that of the tricyclics, and so their acceptability/safety becomes a selection criterion for the clinician. However, side-effect assessment comes up against several difficulties: distinguishing between somatic symptoms caused by the depression and those caused by the treatment -- which assessment tool to use (spontaneous notification, standardized scales that are not specific for the side effects caused by psychotropic drugs, standardised scales specific for the side effects caused by psychotropic drugs, meta-analysis, etc.) -- which data sources to consult (anecdotal reports, reviews, prospective studies), and which data set to use, etc. As a result, the question of the exhaustiveness and reliability of the data consulted by the clinician can arise. We therefore conducted a comparative study in patients treated with these newer antidepressants, of 2 antidepressants side-effect assessment tools: spontaneous notification (SN) versus the UKU scale, a standardised scale specific for the side effects of psychotropic drugs. The depressed outpatients were selected from a psychiatric unit in a French psychiatric hospital and from a non-hospital consulting room. The main inclusion criteria were: male or female subjects, suffering from major depression without melancholia or psychotic features or suffering from mood disorders (according to DSM IV criteria), who had been treated for at least 4 weeks with one of the newer antidepressants. The main exclusion criteria were: any other psychiatric disorder, a serious physical disorder, treatment with neuroleptics, mood-changing drugs or other antidepressants, and patients who were not able to understand the questionnaire. The investigation was carried out by a clinical pharmacist

    To describe the development of a new test of bimanual performance for adults following Stroke, the Adult-Assisting Hand Assessment Stroke, and to report the evidence of internal and external validity. Scale development included: (i) establishing the test situation; (ii) constructing test items; (iii) evaluating internal construct validity by use of Rasch measurement analysis on 144 assessments of adults with hemiparesis, mean age 53 years (SD11.45); and (iv) investigating external validity by correlation to the Jebsen and Taylor Test of Hand Function and the ABILHAND Stroke. The Adult-Assisting Hand Assessment Stroke scale, scored on 19 items using a four-point rating scale, provided a valid measure of bimanual performance. The rating scale structure, goodness of fit, and principal component analysis demonstrated evidence of a unidimensional construct. The strong reliability and high person separation ratio indicated high probability for the scale to be responsive to change. Correlation to outcomes of the Jebsen and Taylor Test of Hand Function and the ABILHAND Stroke indicated strong external validity. Using two hands together is a critical aspect for performance of most daily life tasks. However, assessments of hand function commonly focus on measuring aspects of unimanual function. The Adult-Assisting Hand Assessment Stroke has the potential to contribute new and clinically important knowledge to stroke rehabilitation by providing an observation-based valid functional measure of bimanual performance. Implications for rehabilitation Hand function assessments commonly focus on unimanual aspects, although the use of two hands together is critical to perform most daily life tasks. The Adult-Assisting Hand Assessment Stroke measures how effectively a patient with a hemiparesis uses his/her affected hand together with the unaffected hand to perform bimanual tasks. The Adult-Assisting Hand Assessment Stroke contributes a new and clinically important aspect to stroke

    OBJECTIVE Compliance with hand hygiene in healthcare workers is fundamental to infection prevention yet remains a challenge to sustain. We examined fidelity reporting in interventions to improve hand hygiene compliance, and we assessed 5 measures of intervention fidelity: (1) adherence, (2) exposure or dose, (3) quality of intervention delivery, (4) participant responsiveness, and (5) program differentiation. DESIGN Systematic review METHODS A librarian performed searches of the literature in PubMed, Cumulative Index to Nursing and Allied Health (CINAHL), Cochrane Library, and Web of Science of material published prior to June 19, 2015. The review protocol was registered in PROSPERO International Prospective Register of Systematic Reviews, and assessment of study quality was conducted for each study reviewed. RESULTS A total of 100 studies met the inclusion criteria. Only 8 of these 100 studies reported all 5 measures of intervention fidelity. In addition, 39 of 100 (39%) failed to include at least 3 fidelity measures; 20 of 100 (20%) failed to include 4 measures; 17 of 100 (17%) failed to include 2 measures, while 16 of 100 (16%) of the studies failed to include at least 1 measure of fidelity. Participant responsiveness and adherence to the intervention were the most frequently unreported fidelity measures, while quality of the delivery was the most frequently reported measure. CONCLUSIONS Almost all hand hygiene intervention studies failed to report at least 1 fidelity measurement. To facilitate replication and effective implementation, reporting fidelity should be standard practice when describing results of complex behavioral interventions such as hand hygiene. PMID:26861117

    Food produced with satisfactory hygienic standards is one of the essential conditions for promoting and preserving health. A total of 15 grocery and dairy shops were randomly selected from Alexandria, Egypt to assess their hand washing facilities and personal hygiene of food handlers using a pre-designed sanitation checklist. Also the bacteriological profile of the handlers' hand washes was determined. Only 20% of these shops were acceptable concerning their hand washing facilities ((3) 50% score percentages). Observing 29 food handlers revealed that only 3.4% of them were acceptable in their personal hygiene with a mean score percentage of only 31.0 +/- 9.2. Although the hand washing method followed by the food handlers significantly decreased both aerobic mesophilic and staphylococci counts, they were still high. Moreover, fecal coliforms increased insignificantly from 5 to 7 MPN/100ml indicating that the hand washing was improperly done due several pitfalls. Most of the handlers who washed their hands for less than 10 seconds (41.4%) had higher counts of aerobic mesophiles and staphylococci than those who washed for more 10 seconds. Most of the handlers (93.1%) did not avoid contamination from the tap after hand washing. Moreover, their hand washes were contaminated with fecal coliforms (8 MPN/100ml) and with slightly higher staphylococci counts than those who avoid contamination either by rinsing a tap or closing it by elbow. Much effort should be done from the responsible authority to improve the sanitation inside these shops and food handlers should be given in-service training to know how to efficiently wash their hands.

    The evaluation of hand function impairment following a neurological disorder (stroke and cervical spinal cord injury) requires sensitive, reliable and clinically meaningful assessment tools. Clinical performance measures of hand function mainly focus on the accomplishment of activities of daily living (ADL), typically rather complex tasks assessed by a gross ordinal rating; while the motor performance (i.e. kinematics) is less detailed. The goal of this study was to develop a low-cost instrumented glove to capture details in grasping, feasible for the assessment of hand function in clinical practice and rehabilitation settings. Different sensor types were tested for output signal stability over time by measuring the signal drift of their step responses. A system that converted sensor output voltages into angles based on pre-measured curves was implemented. Furthermore, the voltage supply of each sensor signal conditioning circuit was increased to enhance the sensor resolution. The repeatability of finger bending trajectories, recorded during the performance of three ADL-based tasks, was established using the intraclass correlation coefficient (ICC). Moreover, the accuracy of the glove was evaluated by determining the agreement between angles measured with the embedded sensors and angles measured by traditional goniometry. In addition, the feasibility of the glove was tested in four patients with a pathological hand function caused by a cervical spinal cord injury (cSCI). A sensor type that displayed a stable output signal over time was identified, and a high sensor resolution of 0.5° was obtained. The evaluation of the glove's reliability yielded high ICC values (0.84 to 0.92) with an accuracy error of about ± 5°. Feasibility testing revealed that the glove was sensitive to distinguish different levels of hand function impairment in cSCI patients. The device satisfied the desired system requirements in terms of low cost, stable sensor signal over time, full

    The Southampton Hand Assessment Procedure (SHAP) evaluates the functionality of normal, injured or prosthetic hands. The aim was to evaluate the learning effects of SHAP tasks and the appropriateness of the time limits applied per task in novice prosthetic users. Right-handed unimpaired volunteers (n = 24, mean age 21.8 years) completed 8 SHAP sessions over 5 consecutive days using a prosthetic simulator. The execution times of SHAP tasks were transformed into 6 prehensile patterns, the functionality profile, and the index of function, a general functionality score. Learning effects in task times were analysed using multilevel analysis. Learning effects occurred in all SHAP tasks. Tasks, sex, sessions, tasks-sessions interaction, and the first session of the day contributed (p  25% of participants in at least the first 3 sessions, which affected the calculation of the functionality profile and index of function scores. The learning effects of SHAP in novice prosthetic users require consideration when conducting a reliability study. SHAP scores in novice prosthetic-hand users are confounded by learning effects and exceeded time limits.

    BACKGROUND: Severity assessment of occupational hand eczema (OHE) is important not only in clinical settings but also in research. Questionnaires with self-rated assessment of severity may be an attractive tool for assessing severity because of their cost efficiency in comparison with expensive...... and extent of eczema, and frequency of eruptions. All participants received a self-administered questionnaire and were asked to classify severity of their OHE on a visual analogue scale from 0 to 10. The relation between DNBII-assessed and self-rated severity was illustrated by a receiver operating...... characteristic analysis. RESULTS: Of 758 patients included in the study, 621 returned the questionnaire and 602 (79%) provided information on self-rated severity. The proportion of severe cases was significantly higher among patients' assessments compared with the rating by the DNBII. Almost 18% were categorized...

    A review of the literature related to in-hand manipulation (IHM) revealed that there is no assessment which specifically measures this construct in the adult population. This study reports the face and content validity of an IHM assessment for adults with impaired hand function based on expert opinion. The definition of IHM skills, assessment tasks and scoring methods identified from literature was discussed in a focus group (n = 4) to establish face validity. An expert panel (n = 16) reviewed the content validity of the proposed assessment; evaluating the representativeness and relevance of encompassing the IHM skills in the proposed assessment tasks, the clarity and importance to daily life of the task and the clarity and applicability to clinical environment of the scoring method. The content validity was calculated using the content validity index for both the individual task and all tasks together (I-CVI and S-CVI). Feedback was incorporated to create the assessment. The focus group members agreed to include 10 assessment tasks that covered all IHM skills. In the expert panel review, all tasks received an I-CVI above 0.78 and S-CVI above 0.80 in representativeness and relevance ratings, representing good content validity. With the comments from the expert panel, tasks were modified to improve the clarity and importance to daily life. A four-point Likert scale was identified for assessing both the completion of the assessment tasks and the quality of IHM skills within the task performance. Face and content validity were established in this new IHM assessment. Further studies to examine psychometric properties and use within clinical practice are recommended. © 2018 Occupational Therapy Australia.

    Hand hygiene compliance is generally assessed by observation of adherence to the "WHO five moments" using numbers of opportunities as the denominator. The quality of the activity is usually not monitored since there is no established methodology for the routine assessment of hand hygiene technique. The aim of this study was to objectively assess hand rub coverage of staff using a novel imaging technology and to look for patterns and trends in missed areas after the use of WHO's 6 Step technique. A hand hygiene education and assessment program targeted 5200 clinical staff over 7 days at the National University Hospital, Singapore. Participants in small groups were guided by professional trainers through 5 educational stations, which included technique-training and UV light assessment supported by digital photography of hands. Objective criteria for satisfactory hand hygiene quality were defined a priori. The database of images created during the assessment program was analyzed subsequently. Patterns of poor hand hygiene quality were identified and linked to staff demographic. Despite the assessment taking place immediately after the training, only 72% of staff achieved satisfactory coverage. Failure to adequately clean the dorsal and palmar aspects of the hand occurred in 24% and 18% of the instances, respectively. Fingertips were missed by 3.5% of subjects. The analysis based on 4642 records showed that nurses performed best (77% pass), and women performed better than men (75% vs. 62%, phygiene compliance and technique of clinical staff. Identification of typical sites of failure can help to develop improved training.

    The aim of the present study was to incorporate the use of mobile phone photo-messaging into clinical practice, in order to explore its potential advantages and limitations in the context of communication between the registrar and consultant for the assessment of hand trauma. Two Nokia 7650 mobile phones (Nokia, Sydney, Australia) were obtained. These were used for correspondence between the registrar and the consultant for all hand trauma seen in the emergency department over a 2-month period. There were 27 cases recorded. Deductions were drawn form the use of the phone and the collected data was qualitatively interpreted. The present paper describes our findings and approval of the use of mobile phones with photo-messaging capabilities for the purpose of enhancing communication in a clinical setting. Low cost and ease of use make the phones easily incorporated into clinical practice.

    It is thought that therapy should be functional, be highly repetitive, and promote afferent input to best stimulate hand motor recovery after stroke, yet patients struggle to access such therapy. We developed the MusicGlove, an instrumented glove that requires the user to practice gripping-like movements and thumb-finger opposition to play a highly engaging, music-based, video game. The purpose of this study was to 1) compare the effect of training with MusicGlove to conventional hand therapy 2) determine if MusicGlove training was more effective than a matched form of isometric hand movement training; and 3) determine if MusicGlove game scores predict clinical outcomes. 12 chronic stroke survivors with moderate hemiparesis were randomly assigned to receive MusicGlove, isometric, and conventional hand therapy in a within-subjects design. Each subject participated in six one-hour treatment sessions three times per week for two weeks, for each training type, for a total of 18 treatment sessions. A blinded rater assessed hand impairment before and after each training type and at one-month follow-up including the Box and Blocks (B & B) test as the primary outcome measure. Subjects also completed the Intrinsic Motivation Inventory (IMI). Subjects improved hand function related to grasping small objects more after MusicGlove compared to conventional training, as measured by the B & B score (improvement of 3.21±3.82 vs. -0.29±2.27 blocks; P=0.010) and the 9 Hole Peg test (improvement of 2.14±2.98 vs. -0.85±1.29 pegs/minute; P=0.005). There was no significant difference between training types in the broader assessment batteries of hand function. Subjects benefited less from isometric therapy than MusicGlove training, but the difference was not significant (P>0.09). Subjects sustained improvements in hand function at a one month follow-up, and found the MusicGlove more motivating than the other two therapies, as measured by the IMI. MusicGlove games scores correlated

    Targeted spontaneous reporting (TSR) is a pharmacovigilance method that can enhance reporting of adverse drug reactions related to antiretroviral therapy (ART). Minimal data exist on the needs or capacity of facilities to conduct TSR. Using data from the International epidemiologic Databases to Evaluate AIDS (IeDEA) Consortium, the present study had two objectives: (1) to develop a list of facility characteristics that could constitute key assets in the conduct of TSR; (2) to use this list as a starting point to describe the existing capacity of IeDEA-participating facilities to conduct pharmacovigilance through TSR. We generated our facility characteristics list using an iterative approach, through a review of relevant World Health Organization (WHO) and Uppsala Monitoring Centre documents focused on pharmacovigilance activities related to HIV and ART and consultation with expert stakeholders. IeDEA facility data were drawn from a 2009/2010 IeDEA site assessment that included reported characteristics of adult and pediatric HIV care programs, including outreach, staffing, laboratory capacity, adverse event monitoring, and non-HIV care. A total of 137 facilities were included: East Africa (43); Asia-Pacific (28); West Africa (21); Southern Africa (19); Central Africa (12); Caribbean, Central, and South America (7); and North America (7). Key facility characteristics were grouped as follows: outcome ascertainment and follow-up; laboratory monitoring; documentation-sources and management of data; and human resources. Facility characteristics ranged by facility and region. The majority of facilities reported that patients were assigned a unique identification number (n = 114; 83.2 %) and most sites recorded adverse drug reactions (n = 101; 73.7 %), while 82 facilities (59.9 %) reported having an electronic database on site. We found minimal information is available about facility characteristics that may contribute to pharmacovigilance activities. Our findings

    BACKGROUND Previous studies from our group have demonstrated that IgE-mediated basophil activation leads to release of TNFα that in turn can induce matrix metallo-proteinase-9 (MMP-9) release from monocytes. We wished to investigate if serum from chronic spontaneous urticaria-patients with auto......-antibodies against IgE/IgE-receptor could induce TNFα and MMP-9 release from donor PBMCs, and if release levels could be used to assess severity and activity of chronic spontaneous urticaria (CSU). METHODS Peripheral blood mononuclear cells (PBMCs) were isolated from whole blood from healthy donors and basophils......&D), and histamine release determined with HR-test from RefLab ApS. RESULTS Stimulations with serum-pools demonstrated that CSU-serum, in contrast to healthy controls, was able to induce TNFα-release from isolated basophils. 10 sera from healthy controls and 22 sera from CSU-patients were tested for serum...

    A simple experimental paradigm creates the powerful illusion that one is touching one's own hand even when the two hands are separated by 15 cm. The participant uses her right hand to administer stimulation to a prosthetic hand while the Examiner provides identical stimulation to the participant's receptive left hand. Change in felt position of the receptive hand toward the prosthetic hand has previously led to the interpretation that the participant experiences self-touch at the location of the prosthetic hand, and experiences a sense of ownership of the prosthetic hand. Our results argue against this interpretation. We assessed change in felt position of the participant's receptive hand but we also assessed change in felt position of the participant's administering hand. Change in felt position of the administering hand was significantly greater than change in felt position of the receptive hand. Implications for theories of ownership are discussed.

  7. Preliminary study of the Southampton Hand Assessment Procedure for Children and its reliability

    Science.gov (United States)

    2014-01-01

    Background The Southampton Hand Assessment Procedure (SHAP) is currently used in the adult population for evaluating the functionality of impaired or prosthetic hands. The SHAP cannot be used for children because of the relatively larger size of the objects used to perform SHAP tasks and unknown clinimetric properties. The aims of this study were to adapt the SHAP for use in children (SHAP-C), to determine norm values for the SHAP-C, and to analyze the reliability of the SHAP-C. Methods The SHAP-C was adapted based on the SHAP protocol. Some objects were downsized, and the timing of tasks was performed by the rater instead of the participant. Intra- and inter-rater reliability were assessed in 24 children (5 [0.54] y/o) with unimpaired hands. The repeatability coefficients (RCs) were calculated. An RC ≤ 75% of the mean SHAP-C task values was considered good reliability. Results Participants were able to perform all SHAP-C tasks. The means of the SHAP-C tasks ranged from 0.75 to 1.21 seconds for abstract objects and from 0.64-19.13 seconds for activities of daily living. The RCs of a single assessor did not exceed 75% in 17/26 SHAP-C tasks, displaying a relatively good intra-rater reliability, whereas the RCs for the inter-rater reliability exceeded 75% in 22/26 SHAP-C tasks, thus displaying poor reliability. Conclusion In this first study that adjusted the SHAP for pediatric use, we found that all SHAP-C objects and tasks could be performed by children. The intra-rater reliability was better than the inter-rater reliability. Although the SHAP-C appears to be a promising instrument, the protocol requires further modifications to provide reliable measurements in children. PMID:24916917

    The assessment of nutritional status in clinical practice must be done with simple, reliable, low cost and easy performance methods. The power of handshake is recognized as a useful tool to evaluate muscle strength, and therefore, it is suggested that can detect malnutrition. To evaluate the nutritional status by subjective global assessment and power of handshake preoperatively in patients going to gastrointestinal surgeries and to compare the diagnosis obtained by subjective global assessment with traditional anthropometric methods and power of handshake. A cross-sectional study was conducted with patients for surgery in the gastrointestinal tract and related organs. Socioeconomic and anthropometric data, applied to subjective global assessment and checked the power of handshake, were collected. The force was obtained by the average of three measurements of the dominant and non-dominant hand and thus compared with reference values of the population by sex and age, for the classification of nutritional risk. The sample consisted of 40 patients, 24-83 years, and most women (52.5%) housewives (37,5%) and diagnosed with cancer (45%). According to subjective global assessment, 37.5% were classified as moderately malnourished; 15% were underweight by BMI measurements; 25% had arm circumference at risk for malnutrition (nutritional subjective assessment with anthropometric methods and strength of the handshake only at the non-dominant limb.

Conclusion Ongoing education and training has a vital role in improving hand hygiene compliance and technique of clinical staff. Identification of typical sites of failure can help to develop improved training. PMID:23718728

    It is only recently that life cycle-based indicators have been used to evaluate products from a water use impact perspective. The applicability of some of these methods has been primarily demonstrated on agricultural materials or products, because irrigation requirements in food production can be water-intensive. In view of an increasing interest on life cycle-based water indicators from different products, we ran a study on a hand dishwashing product. A number of water assessment methods were applied with the purpose of identifying both product improvement opportunities, as well as understanding the potential for underlying database and methodological improvements. The study covered the entire life cycle of the product and focused on environmental issues related to water use, looking in-depth at inventory, midpoint, and endpoint methods. "Traditional" water emission driven methods, such as freshwater eutrophication, were excluded from the analysis. The use of a single formula with the same global supply chain, manufactured in 1 location was evaluated in 2 countries with different water scarcity conditions. The study shows differences ranging up to 4 orders in magnitude for indicators with similar units associated with different water use types (inventory methods) and different cause-effect chain models (midpoint and endpoint impact categories). No uncertainty information was available on the impact assessment methods, whereas uncertainty from stochastic variability was not available at the time of study. For the majority of the indicators studied, the contribution from the consumer use stage is the most important (>90%), driven by both direct water use (dishwashing process) as well as indirect water use (electricity generation to heat the water). Creating consumer awareness on how the product is used, particularly in water-scarce areas, is the largest improvement opportunity for a hand dishwashing product. However, spatial differentiation in the inventory and

    Full Text Available Skeletal age assessment (SAA is a clinical procedure which is used in determining the SA of children and adolescents. Bone development is influenced by a number of factors, including nutrition, hormonal secretions, and genetics. There are several factors to be borne in mind when using methods of assessing skeletal maturity. These include: Variability among methods, degree of variability in the estimation of skeletal maturation, sources of low accuracy, and dispersion of the values of skeletal maturation. Currently, the main clinical methods for SAA are the Greulich and Pyle (GP and Tanner and Whitehouse (TW methods. The GP method has the advantage of being quick and easy to use. A well-trained radiologist takes few minutes to determine the bone age (BA from a single hand radiograph. The method of TW, however, seems to be more reliable than the GP method. In recent years, the increasing speed in computer sciences and reduction of their cost has given the opportunity to create and use computerized BA estimation system. Despite the fact that the number of automated systems for BAA have increased, most are still within the experimental phase. The use of automated BA determination system, cleared for clinical use in Europe (BoneXpert, has been validated for various ethnicities and children with endocrine disorders. Ultrasound imaging has some limitations that include operator dependence, lower intra-rater and inter-rater reliability of assessment and difficulties with standardization of documentation and imaging transfer. Magnetic resonance imaging (MRI is noninvasive alternative tool for SA assessment in children. However, few studies have been reported on this topic, and further research is needed to evaluate the reliability and validity of MRI BAAs. In conclusion, at present radiographic methods for the assessment of BA remain the gold standards. Whatever method one adopts, it is essential to minimize the causes of imprecision by taking care to

    A visual analogue scale was developed by French rheumatologists to measure the impact caused by rheumatoid arthritis of the hand (VAS-Hand). This article reports the use of the measure. First, the validity of the VAS-Hand was investigated by interviewing patients to understand how they interpreted and answered these questions. Second, the measure was compared with disability, pain, and impairment measures to determine whether it provided additional information. Finally, the repeatability of the measure was defined as within 1.5 points out of ten. The visual analogue scale of handicap from rheumatoid arthritis of the hand provides different information than do health status or disability questionnaires, or strength and motion assessment. The responsiveness of the VAS-Hand is under investigation in a longitudinal study.

    Catching crew members can heavily contaminate their hands with organic material. They can act as mechanical vector and spread diseases between farms. Hand hygiene is an important issue for the industry as a whole and for human health by reducing contamination risks. Many studies, in human medicine, tend to make hand rub a standard for hand hygiene. However, few studies have tested the effectiveness of hand hygiene products on visibly contaminated hands. The objective of this study was to evaluate the effectiveness of practical hand sanitization protocols: water and soap, degreasing cream and hand wipes, all combined with alcohol-based hand gel. The use of alcohol-based gel alone was also evaluated. For the reduction of coliforms after washing, there was no statistically significant difference between protocols when the initial level of bacterial contamination was low to moderate. When hands were highly contaminated, the alcohol-based gel alone was less effective than the degreasing cream combined with the alcohol-based gel (p=0.002). As for the reduction in total aerobic bacteria counts, there was no difference between protocols when the initial level of bacterial contamination was low. The water, soap and alcohol-based gel protocol was more effective than the scrubbing wipes and alcohol-based gel protocol when hands were moderately (p=0.002) and highly contaminated (p=0.001). All protocols were effective in neutralizing Salmonella on hands. Reducing the level of bacterial contamination on hands before using an alcohol-based gel seems important to ensure effective hand sanitation for highly and moderately contaminated hands. This can be done by using a degreasing cream or water and soap. Based on the survey, catching crew members preferred using warm water and soap compared to a degreasing cream. Crown Copyright © 2013.

    ALSFRS-r is a widely accepted rating scale for measuring the global function of Amyotrophic Lateral Sclerosis (ALS) patients, but we found some limitations of ALSFRS-r in assessing the function of non-dominant hand in Chinese ALS patients. We reviewed 95 ALS patients who expressed upper-limb symptoms at first visit and analyzed the ALSFRS-r score and subscale. In both upper limb involved patients, the ALSFRS-r had no difference between dominant-hand and non-dominant-hand onset groups (39.15±5.55 vs 38.0±5.91, p=0.477). But in only one upper limb involved patients, the ALSFRS-r score in non-dominant-hand onset patients was higher than dominant-hand onset patients (43.94±3.44 vs 40.87±4.42, pr score was significantly lower than original ALSFRS-r (43.94±3.44 vs 42.88±3.07 p=0.001), the progression rate was slower (0.81±0.63 vs 0.64±0.63, p=0.001). So, for Chinese ALS patients, using food bowl and chopsticks should replace the item of cutting food and handling utensils to assess the non-dominant-hand function, especially in non-dominant-hand onset patients.

    A hand-held computerized optical device (HCOD) that can be used by a layperson has been developed which is capable of imaging facial skin and assessing multiple skin attributes, including discoloration. The aim of this study was to assess the HCOD's ability to measure changes in discoloration induced over an 8-week course of treatment by comparing data obtained from the HCOD with the assessments of a trained research dermatologist. Ten female Caucasian subjects, aged between 41 and 79 years, exhibiting moderate facial dyspigmentation used a combination 0.01% fluocinolone acetonide, 4% hydroquinone, and 0.05% tretinoin cream twice daily for 8 weeks. Subjects were evaluated at weeks 0, 4, and 8 by a dermatologist. Images were also taken with high resolution digital photography and with the HCOD. Human testing was directed by a dermatologist, used approved consent forms, and products approved by the FDA. Facial dyspigmentation as scored by a clinician significantly decreased from 4.10 to 2.70 by week 8. HCOD discoloration area scores also significantly decreased from 100,989 to 87,276 by week 8. Assessment of pigmented area by the HCOD proved to be the most reliable in terms of correlating to a clinician's score. Limitations The study had a small sample size and was not placebo controlled because the effectiveness of the HCOD was being evaluated, not the skin lightening product. The HCOD's discoloration area count statistically correlated with the clinician dyspigmentation scores when evaluating the effect of a prescription skin lightening cream on subjects with moderate facial discolorations.

    To explore the differences, relationship, and extent of agreement between the Assisting Hand Assessment (AHA), measuring observed ability to perform bimanual tasks, and the Children's Hand-Use Experience Questionnaire (CHEQ), assessing experienced bimanual performance. This study investigates a convenience sample of 34 children (16 girls) with unilateral cerebral palsy aged 6-18 years (mean 12.1, SD 3.9) in a cross-sectional design. The AHA and CHEQ subscales share 8-25% of their variance (R2). Bland-Altman plots for AHA and all three CHEQ subscales indicate good average agreement, with a mean difference approaching zero but large 95% confidence intervals. Limits of agreement were extremely wide, indicating considerable disagreement between AHA and CHEQ subscales. AHA and CHEQ seem to measure different though somewhat related constructs of bimanual performance. Results of this investigation reinforce the recommendation to use both instruments to obtain complementary information about bimanual performance including observed and perceived performance of children with unilateral cerebral palsy.

    The aim was to assess the variability of spontaneous blink rate (SBR) with and without a chin and forehead support. Forty-eight healthy non-contact lens wearers, aged from 20 to 39 years, had five-minute video recordings made under ambient lighting of 350 to 400 lux, while directing their gaze to a distant target at head height. Half the subjects (group 1) were seated resting against the chair head rest and the other half (group 2) seated but with chin and forehead at a slitlamp. The first 35 blinks were analysed in detail. As assessed over five minutes, 35 to 111 blinks were counted, with SBR between 6.9 and 21.8 blinks per min (average 13.9 per min). Over the initial 35 blinks, the average momentary SBR values (calculated from the inter-blink intervals) averaged 24.8 blinks per minute in group 1 and 19.3 blinks per minute in group 2 (not significantly different, p = 0.273) but a statistically significant (p blinks in group 2. The variability in momentary SBR values, as assessed from successive blinks, had coefficient of variation (COV) values of 80 and 78 per cent, respectively over 35 blinks. Averaged spontaneous blink rates over short time periods (that is, five minutes) should be suitable to compare various experimental paradigms but if very short periods are used (for example one minute or less), then there could be significant time-related changes, especially when a subject is seated with chin and forehead support. © 2016 Optometry Australia.

    Synthetic oxytocin, the primary tool for labor augmentation, is less effective among obese women, leading to more unplanned cesarean deliveries for slow labor progress. It is not known if obese women require higher doses of oxytocin due to maternal, fetal, or labor factors related to maternal obesity. This study had two main objectives: (1) examine the influence of maternal body mass index (BMI) on hourly doses of oxytocin from augmentation initiation until vaginal delivery in obese women; and (2) examine the influence of other maternal, fetal, and labor factors on hourly doses of oxytocin in obese women. Longitudinal study of a cohort ( N = 136) of healthy, nulliparous, spontaneously laboring obese women (BMI ≥ 30 kg/m 2 ) who received oxytocin augmentation and achieved vaginal delivery. We performed iterative multilevel analyses to examine the influence of maternal BMI and other factors on hourly oxytocin doses. Maternal BMI explained 16.56% (95% confidence interval [CI] = [13.7, 20.04], p oxytocin doses received in a multilevel model controlling for influence of maternal, fetal, and labor characteristics. Maternal age, gestational age, status of amniotic membranes at hospital admission, and admission cervical dilation examination were not significant; however, neonatal birthweight and cervical dilation at oxytocin initiation were significant predictors of hourly oxytocin dose in these women ( p oxytocin used for augmentation.

    Background Omalizumab is a monoclonal antibody, indicated for the treatment of severe allergic asthma. In Europe, there have been concerns about the cardiovascular safety of omalizumab. The objective of this study was to analyze the association between omalizumab and arterial thrombotic events in a spontaneous adverse drug reaction reporting database in the US. Methods and materials Reports of arterial thrombotic events submitted to the US Food and Drug Administration’s Adverse Event Reporting System (AERS) between 2004 and 2011 were retrieved and analyzed by the reporting odds ratio data mining algorithm. The reporting odds ratio of arterial thrombotic events for omalizumab was compared with specific asthma medications and all drugs in the AERS. Values ≥2 were considered significant safety signals. The Medical Dictionary for Regulatory Activities Preferred Terms were used to identify arterial thrombotic events (eg, stroke, myocardial infarction). Results In total, 293,783 reports of arterial thrombotic events were retrieved (about 2% of all adverse drug reaction reports), corresponding to 2274 asthma drug-arterial thrombotic events pairs (omalizumab, 222; inhaled corticosteroids [ICS], 131; long-acting beta-agonists [LABA], 102; single-device combination ICS-LABA, 506; inhaled short-acting beta-agonists [SABA], 475; oral SABA, 6; inhaled antimuscarinics [AMC], 477; single-device combination AMC-SABA, 127; xanthines, 50; leukotriene modifiers, 174; and mast cell stabilizers, 4). Reporting odds ratio and 95% confidence interval values for omalizumab compared with other asthma drugs and all drugs in AERS were 2.75 (2.39–316) and 1.09 (0.95–1.24), respectively. Omalizumab ranked second after ICS in the risk of arterial thrombotic events, followed by AMC, AMC-SABA, and ICS-LABA. Conclusion Omalizumab is associated with higher than expected reporting of arterial thrombotic events in asthmatic patients. This hypothesis needs further testing in robust

    Full Text Available Objective: Patients receiving haemodialysis treatment generally tend to avoid using the upper extremity with arteriovenous (AV fistulae and it results in impairment of hand functions. Limited data are available about impairment associated with hand complications in those patients The aim of this pilot study is to evaluate the handgrip and pinching strengths and functional level of both hands in patients receiving haemodialysis. Methods: Fifteen chronic renal failure patients receiving haemodialysis (30-83 years and 11 age-matched healthy volunteers participated in the study. All the patients were undergoing treatment through arteriovenous fistulae in the upper extremity. Handgrip strength with a manual dynamometer and pinch strength with a pinchmeter were measured. Functional level of both hands was evaluated with Nine-Hole Peg Test. Results: Handgrip strengths of both hands were lower in patients receiving haemodialysis than healthy control group (p0.05. 9-Hole Peg Test results in both placement and removal showed a great significant difference in both hands with a statistical significance of p<0.001. Conclusion: Our first results revealed that chronic renal failure patients receiving haemodialysis treatment through arteriovenous fistulae in the upper extremity have a significant impairment in strength and functional level of hand. The lack of differences between two hands may be concluded that the upper extremity impairment in patients results from the disease course or haemodialysis treatment, not from the vascular access.

    The Stockholm Workshop Scale (SWS) provides a staging scheme for hand-arm vibration syndrome (HAVS) based on subjective history. Cold provocation finger thermometry and plethysmography are commonly used objective tests for the vascular component of HAVS. To examine the correlation between the cold provocation tests and SWS vascular stage. A secondary goal was to evaluate the correlation between cold provocation finger plethysmography and thermometry testing. Patients investigated for HAVS at St Michael's Hospital, Toronto, Ontario, were subjected to the same protocol including a questionnaire, clinical assessment and objective testing. Spearman correlation coefficients were calculated for the vascular tests with the SWS and for the vascular tests themselves. Logistic regression models controlled for age, smoking, use of vasoactive medications and time since last vibration exposure. One hundred and thirty-nine patients investigated for HAVS consented to participate in the study. The correlation coefficients for plethysmography (rho = 0.14) and thermometry (rho = 0.18) with the SWS were not statistically significant. Plethysmography and thermometry results were significantly correlated (rho = 0.47, P < 0.001). Logistic regression showed plethysmography and thermometry to weakly predict SWS vascular stage (OR 1.5 and 1.3, respectively). None of the potential confounders had a significant effect in the models. The results of plethysmography and thermometry did not significantly correlate with SWS vascular stage in this study. The objective tests did correlate with each other, suggesting that they are reliable measures of similar phenomena likely related to underlying vascular pathology.

    Alcohol-based hand rubs (ABHRs) have been associated with a reduction of nosocomial infections. Despite the worldwide introduction of these products in health care settings, the aim of this study was to assess the transpulmonary absorption of ethanol contains in ABHRs used by health care workers (HCWs) in real conditions of work shift. Twenty-six HCWs of Nancy University Hospital were included. Research consisted in monitoring participants during 4 hours of work shift to assess their exposure to ethanol. The measurement of ethanol vapors in exhaled breath was performed using a class B ethylometer (Alco-Sensor FST). Ethanol concentration in inhaled breath was measured using Gilian pump LFS-113. Concentration of ethanol, acetaldehyde, and acetate in blood and urine samples were determined using gas chromatography with flame ionization detector. Participants were 12% male and 88% female. The mean age was 40 ± 8 years. None of the employees included in the study presented any traces of ethanol or its metabolites in the blood or urine. Ethanol (0.08 ± 0.07 mg/L) was detected in the breath of 10 HCWs at 1 to 2 minutes postexposure. The mean concentration of ethanol in the inhaled air was 46.2 mg/m. Absorption of ethanol vapor from ABHRs among HCWs during their care activities was not detected. Quantification of ethanol fumes inhaled during 4 hours of work shift was below the regulatory limitations of exposure to ethanol.

    Most nosocomial infections are thought to be transmitted by the hands of health care workers. The aim of this work was to assess the knowledge, attitude and practice of hand washing among health care workers (HCW) in Ain-Shams University hospitals and to investigate the presence of the necessary facilities and supplies required for hand washing (HW) in ten wards. A cross-sectional descriptive and observational study was conducted for six months from June till November 2006. Observation of the HCW for hand washing practice was done at any opportunity of contact with the patients in the different wards by members of the infection control team. Knowledge & attitude of HCW towards hand hygiene was done through self-administered questionnaire to HCW in 10 different departments. The total opportunities observed were 2189 opportunities. Doctors showed a significantly higher compliance (37.5%) than other groups of HCW (P = 0.000), however only 11.6% of the opportunities observed for doctors were done appropriately. The most common type of HW practiced among HCW was the routine HW (64.2%) and the least was the antiseptic HW (3.9%). Having a short contact time and improper drying (23.2%) were the most common errors that lead to inappropriate HW. Most of the wards had available sinks (80%) but none of them had available paper towels. The mean knowledge score was higher in nurses compared to doctors (42.6 +/- 1.7 versus 39.1 +/- 10.5). Most of the nurses (97.3%) believe that administrative orders and continuous observation can improve hand washing practices. Implementation of multifaceted interventional behavioral hand hygiene program with continuous monitoring and performance feedback, increasing the supplies necessary for HW and institutional support are important for improving the compliance of hand hygiene guidelines.

    To provide upper-limb amputees with devices that best fit their needs and to test innovative solutions, it is necessary to quantitatively appraise a device performance with rigorous measurement methods. The aim of this work was to define an optimal motion analysis protocol, suitable for optoelectronic systems, to measure the kinematics of poly-articulated hands even when covered by a cosmetic glove. This is a fundamental aspect, because gloves can decrease device speed and range of motion and, ultimately, patients' acceptance of the artificial limb. In this work, different mathematical models of the joints and marker-sets for motion analysis were conceived. A regression model to choose a reduced marker-set for studying the hand performance with different cosmetic glove models was developed. The proposed approaches for finger motion analysis were experimentally tested on the index finger of the i-Limb, a commercial myoelectric poly-articulated prosthetic hand, but the results can be easily extended to the whole hand and to other poly-articulated prosthetic hands. The methods proposed for the performance analysis of prosthetic hands points out that the cosmetic gloves imply a reduction of the finger flexion/extension (F/E) angles and of the motion velocity. This draws attention to the need for performing independent cyclic tests on commercial products with various cosmetic solutions to better guide component selection. © 2017 International Center for Artificial Organs and Transplantation and Wiley Periodicals, Inc.

    Hand hygiene (HH) has a low rate of adherence worldwide. This study aimed to estimate the HH adherence rate before and after the implementation of the multimodal strategy and to perform a self-assessment of an institution for promotion and practice of HH. Before and after study, conducted in a university hospital. Professionals of the medical and nursing staff were included. Data collection was from October 2013 to July 2015, through observations of the HH opportunities and application of the HH self-assessment instrument for the institution. Descriptive and univariate analysis were performed. A total of 9500 HH opportunities were observed. The rate of adherence to HH in pre-intervention period was 20.8%, compared to 16.2% and 15.7% in post-intervention. Regarding the evaluation of the institution, it did not have an established ongoing program of training of professionals, no feedback of HH rates to professionals. The low rate of HH adherence reflected the evaluation of the institution in relation to its investment in the practice and promotion of HH, showing that the investment policy for HH adherence needs to be reviewed, considering that before the study the hospital has not been trained in the 'My Five Moments for HH'.

    Despite the increasing use of Alcohol-Based Hand Rub solutions, few studies have quantified the concentrations of inhaled ethanol. The aim of this study was to assess ethanol exposure during hygienic and surgical hand disinfection practices. Ethanol concentrations were measured at the nose level of a wooden dummy and human volunteers. Two systems were used in parallel to determine short-term ethanol vapor exposures: activated charcoal tubes followed by gas chromatography analysis and direct reading on a photoionization detector (PID). Exposure was assessed for 4 different sequences (N=10) reproducing hand rubs for simple surgery, nursing care, intensive care and surgical scrub. The ethanol concentrations measured were of a similar order between the dummy and volunteers. The concentrations obtained by PID were higher than the gas chromatography values for the simple care (45%) and nursing care (27%) sequences and reflected specific exposure peaks of ethanol, whereas ethanol concentrations were continuously high for intensive care (440 mg m(-3)) or surgical scrub (650 mg m(-3)). Ethanol concentrations were similar for these two exposure assessment methods and demonstrated a relationship between handled doses and inhaled doses. However, the ethanol vapors released during hand disinfection were safe for the healthcare workers. Copyright © 2012 King Saud Bin Abdulaziz University for Health Sciences. Published by Elsevier Ltd.

    A well-known problem in spontaneous reporting systems (SRSs) for adverse drug reactions (ADRs) is under-reporting, that is, the problem that not all occurrences of ADRs are reported to the SRS. We look at the question of how to draw statistical conclusions from analyses of SRS data using reporting odds ratios. We will show that certain under-reporting problems play no role in assessing ADRs from SRSs: the results from the analyses turn out to be biased by some specific under-reporting problems, but not by others. SRS data can be particularly useful for the assessment of drug-drug interactions. If the assumption holds that there is an under-reporting problem for a first drug, and an under-reporting problem for a second drug, but that these two under-reporting problems do not influence each other, then reporting odds ratios estimated from SRSs are useful for signalling drug-drug interactions in the ADR-experiencing population. Similar results hold for covariate-drug interactions. We illustrate our results using two examples. Copyright 2002 John Wiley & Sons, Ltd.

    Full Text Available We present an approach for quantitative assessment of the arm/hand movements in patients with Parkinson’s disease (PD, from sensor data acquired with a wearable, wireless armband device (Myo sensor. We propose new Movement Performance Indicators that can be adopted by practitioners for the quantitative evaluation of motor performance and support their clinical evaluations. In addition, specific Movement Performance Indicators can indicate the presence of the bradykinesia symptom. The study includes seventeen PD patients and sixteen age-matched controls. A set of representative arm/hand movements is defined under the supervision of movement disorder specialist. In order to assist the evaluations, and for progress monitoring purposes, as well as for assessing the amount of bradykinesia in PD, a total set of 84 Movement Performance Indicators are computed from the sensor readings. Subsequently, we investigate whether wireless armband device, with the use of the proposed Movement Performance Indicators can be utilized: (1 for objective and precise quantitative evaluation of the arm/hand movements of Parkinson’s patients, (2 for assessment of the bradykinesia motor symptom, and (3 as an adequate low-cost alternative for the sensor glove. We conducted extensive analysis of proposed Movement Performance Indicators and results are indicating following clinically relevant characteristics: (i adequate reliability as measured by ICC; (ii high accuracy in discrimination between the patients and controls, and between the disease stages (support to disease diagnosis and progress monitoring, respectively; (iii substantial difference in comparison between the left-hand and the right-hand movements across controls and patients, as well as between disease stage groups; (iv statistically significant correlation with clinical scales (tapping test and UPDRS-III Motor Score; and (v quantitative evaluation of bradykinesia symptom.

    Causality assessment is a fundamental biomedical technique for the signal detection performed by Pharmacovigilance centers in a Spontaneous reporting system. Moreover, it is a crucial and important practice for detecting preventable adverse drug reactions. Among different methods for causality assessment, algorithms (such as the Naranjo, or Begaud Methods) seem for their operational procedure and easier applicability one of the most commonly used methods. With the upcoming of the new European Pharmacovigilance legislation including in the definition of the adverse event also effects resulting from abuse, misuse and medication error, all well-known preventable causes of ADRs, there was an emerging need to evaluate whether algorithms could fulfill this new definition. In this review, twenty-two algorithmic methods were identified and none of them seemed to fulfill perfectly the new criteria of adverse event although some of them come close. In fact, several issues were arisen in applying causality assessment algorithms to these new definitions as for example the impossibility to answer the rechallenge question in case of medication error or AEFI (Adverse Event Following Immunization). Moreover, the exact conditions at which events occurred, as for example dosage or mode of administration should be considered to better assess causality in conditions of abuse/overdose, or misuse as well as in conditions of lack of expected efficacy reports for biotechnological drugs and adverse event occurring after mixing of vaccines. Therefore, this review highlights the need of updating algorithmic methods to allow a perfect applicability in all possible clinical scenarios accordingly or not with the terms of marketing authorization.

    Follow-up examinations are necessary to reveal consequences of burn injuries of the hand that are suitable for treatment. However, many patients do not attend such a check-up. A standardised protocol like the DASH questionnaire can help to get at least a minimum of information. We have tested a new set of questions among 81 patients who have been treated at our institution between 2006 and 2007 because of severe burns of their hand. A new coefficient could be calculated, which can fulfill the requirements of a scoring system after burn injuries of the hand quite well. It can be easily applied so that we recommend its use whenever it is not possible to perform a regular medical examination. © Georg Thieme Verlag KG Stuttgart · New York.

    The structure of DNA is not constantly at its equilibrium point but evolves with time. It is generally accepted that evolution induces a decrease of the guanine-cytosine (GC) content and a concomitant increase of the adenine-thymine (AT) ratio through a biased GC → AT mutation process. Unfortunately, the mechanism behind this natural alteration of the stored genetic information is not fully understood. Here, we use a hybrid QM:QM' approach to assess the link between one of the sources of the spontaneous mutation, the so-called G*C* rare tautomers that arise from a double proton exchange between the bases, and the evolution of the GC-content. Our simulations indicate that the G*C* mutation is mainly accumulated in GC-rich regions rather than being randomly spread, and consequently the GC → AT error tends to locate in coding fragments. That specific preference is indirectly induced by the base pairs containing the mutated point, as they tune the structure of the first hydration-shell that solvates the reactive base pair undergoing tautomerisation. The reorganisation of the explicit water molecules eventually modifies the energy barriers as well as the stability of the genetic error during the process.

    The objective evaluation of depressive mood is thought to be useful for the diagnosis and treatment of depressive disorders. Thus, we investigated psychobehavioral correlates, particularly the statistical associations between momentary depressive mood and behavioral dynamics measured objectively, in patients with major depressive disorder (MDD). Patients with MDD (n = 14) wore a watch-type computer device and rated their momentary symptoms using ecological momentary assessment. Spontaneous physical activity in daily life, referred to as locomotor activity, was also continuously measured by an activity monitor built into the device. A multilevel modeling approach was used to model the associations between changes in depressive mood scores and the local statistics of locomotor activity simultaneously measured. The statistical model constructed indicated that worsening of depressive mood was associated with increased intermittency of locomotor activity, as characterized by a lower mean and higher skewness. Our findings suggest the presence of associations between momentary depressive mood and behavioral dynamics in patients with depression, which may lead to the continuous monitoring of the pathological states of MDD.

    Purpose The current study compared the spontaneous expressive language of children with autism spectrum disorder (ASD) across multiple language sampling contexts: the Autism Diagnostic Observation Schedule (ADOS) and play with an examiner or parent. Method Participants were children with ASD (n = 63; 55 males) with a mean age of 45 months (SD = 3.94; Range = 37-53). The number of utterances produced, percent intelligibility, number of different words, mean length of utterance, and the number of requests, comments, and instances of turn-taking were calculated for the ADOS, examiner-child play, and parent-child play. Children were categorized into Tager-Flusberg et al.'s (2009) developmental language phases for each context. Results Effects of sampling context were identified for all variables examined. The ADOS resulted in fewer utterances and lower structural and pragmatic language performance than examiner- and/or parent-child play. Categorization of children into language phases differed across contexts. Conclusions Use of the ADOS as a language sampling context may lead to underestimating the abilities of young children with ASD relative to play with an examiner or parent. Researchers and clinicians should be aware of context effects, particularly for assessments designed to observe autism symptoms. PMID:25093577

  10. Thermographic Assessment of a Vascular Malformation of the Hand: A New Imaging Modality

    2016-01-01

    Full Text Available Vascular malformations of the hand are rare. Angiography is the current Gold Standard imaging modality. Thermal imaging is an emerging noninvasive, noncontact technology that does not require intravenous contrast agents. We present the case of a patient with an arteriovenous malformation affecting the hand in which thermal imaging has been used as an adjunct to capture baseline images to allow monitoring of progression. We suggest that thermal imaging provides an adjunct that can be used in addition to clinical examination and/or angiography for the diagnosis and routine follow-up of conservatively managed arteriovenous malformations, to monitor progression or vascular steal, and also for recording recurrence after surgical excision for which there is known to be a significant incidence. With the benefit of being a noninvasive imaging modality that does not require intravenous contrast, or ionizing radiation exposure, office-based thermal imaging may become commonplace.

    Hand hygiene has been described as the cornerstone and starting point in all infection control programs, with the hands of healthcare staff being the drivers and promoters of infection in critically ill patients. The objectives of this study were to access healthcare workers compliance with the World Health Organization (WHO) prescribed five moments of hand hygiene as it relates to patient care and to determine the various strata of healthcare workers who are in default of such prescribed practices. The study was an observational, cross-sectional one. Hand hygiene compliance was monitored using the hand hygiene observation tool developed by the WHO. A nonidentified observer was used for monitoring compliance with hand hygiene. The observational period was over a 60-day period from August 2015 to October 2015. One hundred and seventy-six observations were recorded from healthcare personnel. The highest number of observations were seen in surgery, n = 40. The following were found to be in noncompliance before patient contact - anesthetist P = 0.00 and the Intensive Care Unit P = 0.00 while compliance was seen with senior nurses (certified registered nurse anesthetist [CRNA]) P = 0.04. Concerning hand hygiene after the removal of gloves, the following were areas of noncompliance - the emergency room P = 0.00, CRNA P = 0.00, dental P = 0.04, and compliance was seen with surgery P = 0.01. With regards to compliance after touching the patient, areas of noncompliance were the anesthetists P = 0.00, as opposed to CRNA P = 0.00, dental P = 0.00, and Medicine Department P = 0.02 that were compliant. Overall, the rates of compliance to hand hygiene were low. The findings however from our study show that the rates of compliance in our local center are still low. The reasons for this could include lack of an educational program on hand hygiene; unfortunately, healthcare workers in developing settings such as ours regard such programs as being mundane. The observance of hand

    "Ten Test" (TT) is a bedside measure of discriminative sensation, whereby the magnitude of abnormal sensation to moving light touch is normalized to an area of normal sensation on an 11-point Likert scale (0-10). The purposes of this study were to determine reliability parameters of the TT in a cohort of patients presenting to a hand trauma clinic with subjectively altered sensation post-injury and to compare the reliability of TT to that of the Weinstein Enhanced Sensory Test (WEST). Study participants (n = 29, mean age = 37 ± 12) comprised patients presenting to an outpatient hand trauma clinic with recent hand trauma and self reported abnormal sensation. Participants underwent TT and WEST by two separate raters on the same day. Interrater reliability, response stability and responsiveness of each test were determined by the intraclass correlation coefficient (ICC: 2, 1), standard error of measurement (SEM) with 95% confidence intervals (CI) and minimal detectable difference score, with 95% CI (MDD95), respectively. The TT displayed excellent interrater reliability (ICC = 0.95, 95% CI 0.89-0.97) compared to good reliability for WEST (ICC = 0.78, 95% CI 0.58-0.89). The range of true scores expected with 95% confidence based on the SEM (i.e. response stability), was ±1.1 for TT and ±1.1 for WEST. MDD95 scores reflecting test responsiveness were 1.5 and 1.6 for TT and WEST, respectively. The TT displayed excellent reliability parameters in this patient population. Reliability parameters were stronger for TT compared to WEST. These results provide support for the use of TT as a component of the sensory exam in hand trauma.

    Motorized vibrating manure forks were used in beach-cleaning operations following the massive Deepwater Horizon oil spill in the Gulf of Mexico during the summer of 2010. The objectives of this study were to characterize the vibration emissions of these motorized forks and to provide a first approximation of hand-transmitted vibration exposures to workers using these forks for beach cleaning. Eight operators were recruited to operate the motorized forks during this laboratory study. Four fork configurations were used in the study; two motor speeds and two fork basket options were evaluated. Accelerations were measured near each hand as the operators completed the simulated beach-cleaning task. The dominant vibration frequency for these tools was identified to be around 20 Hz. Because acceleration was found to increase with motor speed, workers should consider operating these tools with just enough speed to get the job done. These forks exhibited considerable acceleration magnitudes when unloaded. The study results suggest that the motor should not be operated with the fork in the unloaded state. Anti-vibration gloves are not effective at attenuating the vibration frequencies produced by these forks, and they may even amplify the transmitted vibration and increase hand/arm fatigue. While regular work gloves are suitable, vibration-reducing gloves may not be appropriate for use with these tools. These considerations may also be generally applicable for the use of motorized forks in other workplace environments.

    Research demonstrates that highly self-critical individuals can respond negatively to the initial introduction of a range of therapeutic interventions. Yet touch as a form of therapeutic intervention in self-critical individuals has received limited prior investigation, despite documentation of its beneficial effects for well-being. Using the Forms of Self-Criticism/Self-Reassuring Scale, 15 high- and 14 low- self-critical individuals (from a sample of 139 females) were recruited to assess how self-criticism impacts upon a single instance of focused touch. All participants took part in a hand massage- and haptic control- intervention. Salivary cortisol and alpha amylase, as well as questionnaire measures of emotional responding were taken before and after the interventions. Following hand massage, analyses revealed cortisol decreased significantly across all participants; and that significant changes in emotional responding reflected well-being improvements across all participants. Supplementary analyses further revealed decreased alpha amylase responding to hand massage as compared to a compassion-focused intervention in the same (highly self-critical) individuals. Taken together, the physiological and emotional data indicate high self-critical individuals responded in a comparable manner to low self-critical individuals to a single instance of hand massage. This highlights that focused touch may be beneficial when first engaging highly self-critical individuals with specific interventions. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

    There is no consensus among plastic surgeons regarding what constitutes the scope of hand surgery practice. Due to this lack, there is a wide variability in what hand surgery procedures plastic surgery resident will see and participate in during the course of training. We assessed what faculty members of plastic surgery training programs felt were contained within the scope of practice of hand surgery. A survey was sent to all members of the American Council of Academic Plastic Surgeons. Respondents reported size of department, faculty fellowship training, hand surgery call coverage, and amount of elective hand surgery within their training program. They also identified what procedures were within the scope of hand surgery. Ninety-three responses were received. Thirty-five respondents were certified or eligible for the surgery of the hand examination. Twenty-five respondents had 0 or 1 surgery-of-the-hand surgeon among their faculty. Thirty-nine departments/divisions performed 10 or fewer elective hand surgeries per week. Seventy-eight percent of groups taking hand call reported that all faculty members took hand call regardless of whether they had hand fellowship training. Although nearly all cover hand and wrist infections, only 49% provide care for distal radius fractures. In many residency programs, hand surgery exposure is in the setting of trauma and emergencies. The inclusion of complex elective hand surgeries within a plastic surgery practice and residency program allows residents to see the full spectrum of hand surgery. This allows them to make an informed decision regarding whether to seek subspecialty training and continue the participation of plastic surgeons in the full spectrum of hand surgery.

    Rheumatoid arthritis activity is generally evaluated by using DAS-28 score. But this does not reflect the extent of functional hand impairment, a decisive parameter for patient wellbeing as well as for work disability. Several questionnaires to quantify the hand involvement in RA have been elaborated, amongst which SACRAH has been popular since 2003. But this requires evaluating 23 questions on a visual analogue scale. The questions were reduced to 12 in modified-SACRAH (M-SACRAH) and to only five questions in short form SACRAH (SF-SACRAH) so as to make it easily applicable in daily clinical practice. A study was planned to compare M-SACRAH (already validated) to SF-SACRAH in Indian population as no Indian data are available on the same. A total of 100 patients of RA were evaluated for disease activity using DAS-28 score and hand functions using M-SACRAH and SF-SACRAH. The M-SACRAH and SF-SACRAH were then compared based on DAS-28 scores; also M-SACRAH was compared to SF-SACRAH using Spearman's correlation coefficient. The mean value of DAS-28 score was 3.15 ± 0.86. The mean value of SF-SACRAH was 8.065 ± 7.44, and mean value of M-SACRAH was 201.7 ± 201.1008. The correlation of DAS-28 score to SF-SACRAH and M-SACRAH was significant in moderate and high disease activity but insignificant in remission and low disease activity state. The correlation between M-SACRAH and SF-SACRAH showed a spearman's coefficient of 0.998 with a P value of disease activity states and for remission. The study suggests that the disease activity of rheumatoid arthritis (as assessed by DAS-28 score) has a poor correlation with hand functions (as assessed by M-SACRAH and SF-SACRAH) especially in low disease activity and remission states. Further, M-SACRAH and SF-SACRAH are significantly correlated. Therefore, it is suggested that RA patients should be assessed by SF-SACRAH (which includes five questions only) in addition to DAS-28 scoring for better evaluation of hand functions, a

    Hand hygiene (HH) prevents harmful contaminants spreading in settings including domestic, health care and food handling. Strategies to improve HH range from behavioural techniques through to automated sinks that ensure hand surface cleaning. This study aimed to assess user experience and acceptance towards a new automated sink, compared to a normal sink. An adapted version of the technology acceptance model (TAM) assessed each mode of handwashing. A within-subjects design enabled N = 46 participants to evaluate both sinks. Perceived Ease of Use and Satisfaction of Use were significantly lower for the automated sink, compared to the conventional sink (p design features including jet strength, water temperature and device affordance may improve HH technology. We provide recommendations for future HH technology development to contribute a positive user experience, relevant to technology developers, ergonomists and those involved in HH across all sectors. Practitioner Summary: The need to facilitate timely, effective hand hygiene to prevent illness has led to a rise in automated handwashing systems across different contexts. User acceptance is a key factor in system uptake. This paper applies the technology acceptance model as a means to explore and optimise the design of such systems.

    The objective of this study was an assessment of sympathetic activity within the hand in patients with traumatic, incomplete nerve lacerations. In 12 patients, 1 female and 11 male in the mean age of 30 years with injuries of these nerves within forearm, the sympathetic skin response was obtained with index fingers of the affected and unaffected hand. Capillaroscopy examination of nail folds of the middle fingers was performed in affected and unaffected hand. Over and above, symptoms and signs attributed to the sympathetic function were registered. Mean values of the sympathetic skin response parameters: amplitude and area were statistically significantly reduced in the affected hand, comparing to the unaffected: amplitude 0.5 vs 1.0 mV, area 0.6 vs 1.2 mVms, respectively. Latency was not different between the hands; 1.4 vs. 1.5 ms. Qualitative analysis of the SSR graphs revealed no response in two patients, reduced SSR in 7 and normal SSR in 3 patients. Wide individual variability of the parameters of the sympathetic skin response was observed. Capillaroscopy. Mean diameters of afferent capillary vessels were greater in the affected (11.7 pm) than in the unaffected (10.7 microm) hand, but the difference was not significant. Mean diameters of efferent capillary vessels were statistically significantly greater in the affected (15.2 microm) than in the unaffected (14.2 microm) hand, what may be attributed to reduced sympathetic activity in the distribution of the examined nerve. All patients reported symptoms and signs attributed to sympathetic dysfunction, which majority of them were considered troublesome in their daily life. Results obtained in our study does not allow for a definitive conclusion regarding the severity of sympathetic dysfunction due to partial laceration of the median or median and ulnar nerves. The results indicate on limited ability of employed diagnostic techniques in detection of factual effect of the loss of sympathetic fibres in the median

    Surgical educators are increasingly exploring surgical simulation and other nonclinical teaching adjuncts in the education of trainees. The simulators range from purpose-built machines to inexpensive smartphone or tablet-based applications (apps). This study evaluates a free surgery module from one such app, Touch Surgery, in an effort to evaluate its validity and usefulness in training for hand surgery procedures across varied levels of surgical experience. Participants were divided into 3 cohorts: fellowship-trained hand surgeons, orthopedic surgery residents, and medical students. Participants were trained in the use of the Touch Surgery app. Each participant completed the Carpal Tunnel Release module 3 times, and participants' score was recorded for each trial. Participants also completed a customized Likert survey regarding their opinions on the usefulness and accuracy of the app. Statistical analysis using a 2-tailed t test and analysis of variance was performed to evaluate for performance within and between cohorts. All cohorts performed better on average with each subsequent simulation attempt. For all attempts, the experts outperformed the novice and intermediate participants, while the intermediate cohort outperformed the novice cohort. Novice users consistently gave the app better scores for usefulness as a training tool, and demonstrated more willingness to use the product. The study confirms app validity and usefulness by demonstrating that every cohort's simulator performance improved with consecutive use, and participants with higher levels of training performed better. Also, user confidence in this app's veracity and utility increased with lower levels of training experience.

    Forensic age estimation of living individuals is a controversial subject because of the imprecision of the available methods which leads to errors. Moreover, young persons are exposed to radiation, without diagnostic or therapeutic advantage. Recently, non-invasive imaging techniques such as magnetic resonance imaging (MRI) have been studied in this context. The aim of this work was to study if the analysis of wrist/hand MRI enabled determination of whether a subject was 18 years old. Two observers retrospectively analyzed metaphyseal-epiphyseal fusion of the distal epiphysis of the radius and the ulna and the base of the first metacarpus in wrist/hand MRI of living people between 9 and 25 years of age. A three-stage scoring system was applied to all epiphyses. Intra- and inter-observer variability was excellent. Staging of the distal radial epiphysis allowed the subjects to be correctly evaluated with regard to the 18-year-old threshold in more than 85 % of cases. Analysis of the radius alone was as good as the analysis of the three epiphyses together. Evaluation of the metaphyseal-epiphyseal fusion of the distal radius in wrist MRI gave good results in forensic age estimation. Wrist MRI could meet ethical expectations with regard to the link between the benefit and risk of practicing radiologic examination on individuals in this context.

    A current doctrine in the dynamometric approach to determine lateralization of hand function states that in 10% of cases, the non-dominant hand will be stronger than the dominant hand. In this study, a novel MRI based modelling approach was applied to the first dorsal introsseus muscle (FDI), to determine whether the 10% rule may be applied to the FDI and may be partially explained by the arrangement of the anatomical components of the FDI. Initially the force generated by the thumb segment during an isometric pushing task in the horizontal plane was measured from 25 strongly right-handed young males. Nine of these participants then had structural magnetic resonance imaging (sMRI) of the thumb and index osseous compartment. A modelling technique was developed to extract the muscle data and quantify the muscle line of action onto to the first metacarpal bone segment in order to quantify the muscle force at the point of momentary rotation--equilibrium. Eight of 25 subjects exhibited stronger force from the left hand. Six out of nine subjects from the MRI possessed significantly greater angles of attachment of the index osseous compartment on the left (non-dominant) hand. These six subjects also generated greater maximal isometric forces from the FDI of the left side. There was a significantly greater muscle volume for the right FDI muscle as compared to the left as measured from the reconstructed MRI slice data. The calculated force produced by the muscle is related to the angle of attachment of the muscle to bone in the index osseous compartment. The MRI findings indicate that the 10% rule may be anatomically and biomechanically explained.

    Neonates and infants frequently undergo MRI examinations of the brain or head and neck in spontaneous respiration. This study aims to evaluate the patency of the upper airway and associated risk factors in spontaneously breathing neonates and infants undergoing MRI of head and neck. Airway patency was assessed on sagittal and axial MRI images of the head and neck region for neonates and infants retrospectively. Anteroposterior diameters were measured at the soft palate and tongue levels as well as a lateral diameter at the tongue level for the patent airway. Chart review for risk factors was carried out. A total of 831 children between 0 and 12 months of age had an MRI. Eighty-two children with spontaneous ventilation were included. The airway was occluded in 29/82 (35%) of children. Twenty-four out of 29 (83%) children with airway occlusion had a depressed level of consciousness, 7/24 (29%) of whom were sedated with a single dose of benzodiazepine and 17/24 (71%) were on anti-epileptic therapy for an underlying seizure disorder and/or hypoxic ischemic encephalopathy. Forty-three out of 82 (65%) of children had an open airway. The airway diameters (mean ± SD) were 5.9 ± 2 mm (anteroposterior (AP) at soft palate), 7.4 ± 2.9 mm (lateral at soft palate), and 6.3 mm ± 1.6 (AP at dorsum of tongue). A significant proportion of spontaneously breathing neonates and infants with hypoxic ischemic encephalopathy or sedation show evidence of airway obstruction during MRI. Careful pre-MRI screening for decision of spontaneous breathing versus artificial airway support during MRI and robust airway monitoring during MRI are required for these vulnerable children.

    To investigate the validity, the intraexaminer and interexaminer reproducibility, and the ability to detect change of a hand-held dynamometer (HHD) in strength measurements in former polio subjects. HHD measurement of knee extensor strength was compared with the criterion standard of a chair dynamometer measurement in 49 subjects. The "break" method was used for HHD measurements. Reproducibility was studied for six lower extremity muscle groups in 28 subjects. The measurements were performed by one experienced and one inexperienced examiner on two separate occasions, with an interval of 1 week. The examiners were blinded to each other's and to previous results. University hospital. Volunteer sample of former polio subjects. For knee extension, the forces that could be measured with the HHD were limited to approximately 200N. Although the intraclass correlation coefficients were high (.75 to .98), the 95% limits of agreement between measurements showed large intervals for differences between two measurements (ratio intervals ranging from .76-1.52 to .52-2.77). The intraexaminer reproducibility for the experienced examiner was superior to that of the inexperienced examiner. The reproducibility of the inexperienced examiner showed systematic bias, with significantly higher strength values for the second session measurement of three muscle groups. The device has good validity in the lower force range. However, because the agreement between measurements was poor, it has limited ability to detect a change in muscle strength. Therefore, this method is unable to detect small changes in lower extremity muscle strength in former polio patients.

    The FAMACHA(©) system is a method for selective anthelmintic treatment comprising early detection of haemonchosis in sheep and goats. In order to evaluate the hands-on training methodology and the learning level of the participants, we analyzed data from 30 training events involving 47 training classes conducted in the State of Paraná, Brazil, from July/2009 to May/2011, during which period a total of 1004 participants did 20,080 FAMACHA(©) classifications. In the practical training sessions, each participant individually evaluated 20 animals with known haematocrit values. Every participant per training event was given a unique number, whereupon each of the animals in a given event was FAMACHA(©) classified by all the trainees involved, in the same trainee number sequence. After each consecutive animal had been evaluated by every one of the participants, its haematocrit and corresponding FAMACHA(©) category were announced before the next animal was presented. The number of persons in training, which ranged from 5 to 39 per session, did not significantly affect the average error of the groups of participants involved (p>0.05). The average error in the classification of the first animal on a scale with a perfect score of zero was 2.5, significantly greater than the error of 0.56 of the twentieth one (p0.05).

    To assess the knowledge and use of the Assessment, prevention, and management of pain; spontaneous awakening and breathing trials; Choice of analgesia and sedation; Delirium assessment; Early mobility and exercise; and Family engagement and empowerment (ABCDEF) bundle to implement the Pain, Agitation, Delirium guidelines. Worldwide online survey. Intensive care. A cross-sectional online survey using the Delphi method was administered to intensivists worldwide, to assess the knowledge and use of all aspects of the ABCDEF bundle. There were 1,521 respondents from 47 countries, 57% had implemented the ABCDEF bundle, with varying degrees of compliance across continents. Most of the respondents (83%) used a scale to evaluate pain. Spontaneous awakening trials and spontaneous breathing trials are performed in 66% and 67% of the responder ICUs, respectively. Sedation scale was used in 89% of ICUs. Delirium monitoring was implemented in 70% of ICUs, but only 42% used a validated delirium tool. Likewise, early mobilization was "prescribed" by most, but 69% had no mobility team and 79% used no formal mobility scale. Only 36% of the respondents assessed ICU-acquired weakness. Family members were actively involved in 67% of ICUs; however, only 33% used dedicated staff to support families and only 35% reported that their unit was open 24 hr/d for family visits. The current implementation of the ABCDEF bundle varies across individual components and regions. We identified specific targets for quality improvement and adoption of the ABCDEF bundle. Our data reflect a significant but incomplete shift toward patient- and family-centered ICU care in accordance with the Pain, Agitation, Delirium guidelines.

    Full Text Available Abstract Background Activation of the endothelium, complement activation and generation of cytokines are known events during ischemia-reperfusion (I/R that mediate tissue injury. Our aim was to elucidate their respective participation at the onset of the reperfusion phase. Tourniquet application in hand surgery causes short-term ischemia, followed by reperfusion and was therefore used as the model in this study. Methods Ten patients were included in the study after obtaining informed consent. A tourniquet was placed on the upper arm and inflated to 250 mmHg for 116 ± 16 min, during which the surgery was performed. Venous blood and tissue samples from the surgical area were taken at baseline as well as 0, 2, and 10 min after reperfusion and analyzed for the following parameters: Endothelial integrity and/or activation were analyzed by measuring heparan sulfate and syndecan-1 in serum, and vWF, heparan sulfate proteoglycan as well as CD31on tissue. Complement activation was determined by C3a and C4d levels in plasma, levels of C1-inhibitor in serum, and IgG, IgM, C3b/c, and C4b/c deposition on tissue. Cytokines and growth factors IL-5, IL-6, IL-7, IL-8, IL-10, IL-17, G-CSF, GM-CSF, MCP-1, TNFα, VEGF, and PDGF bb were measured in the serum. Finally, CK-MM levels were determined in plasma as a measure for muscle necrosis. Results Markers for endothelial activation and/or integrity as well as complement activation showed no significant changes until 10 min reperfusion. Among the measured cytokines, IL-6, IL-7, IL-17, TNFα, GM-CSF, VEGF, and PDGF bb were significantly increased at 10 min reperfusion with respect to baseline. CK-MM showed a rise from baseline at the onset of reperfusion (p  Conclusions In this clinical model of I/R injury no damage to the endothelium, antibody deposition or complement activation were observed during early reperfusion. However, an increase of pro-inflammatory cytokines and growth factors was shown

    Full Text Available Abstract Background To identify clinical questions and assessments regarded by health care practitioners as important when assessing undifferentiated hand pain or problems in adults aged 50 years and over presenting to primary care. Methods A purposively selected panel of 26 UK-based Health Care Practitioners comprising occupational therapists, physiotherapists, rheumatologists and general practitioners, were invited to take part in a consensus study involving three postal rounds of a Delphi questionnaire with accompanying case scenarios. Participants were asked to generate questions and assessments (round 1, rate their importance (round 2, and vote on which items were most important (round 3. Results Sixteen Health Care Practitioners agreed to participate with 11 completing all three rounds. The first round of the Delphi study generated 156 questions and 143 assessments. After three rounds agreement was reached on the importance of 25 questions and 19 assessments. Questions were weighted towards current symptoms, but also included the history of previous hand problems, self-reported hand function, co-morbidity and general health. Observation and palpation of features predominated in the choice of assessment, but specific tests, grip strength, evaluation of sensation and hand function were also included. Conclusions A pool of clinical questions and assessments were generated by Health Care Practitioners, and those considered most important for assessing older adults presenting with undifferentiated hand pain and hand problems in primary care were identified. Further evaluation is required to establish the reliability and feasibility of using these questions and assessments in primary care. In particular, the relative contribution of these questions and assessments in evaluating the nature and severity of hand problems, assisting diagnosis, indicating appropriate management, and predicting future course requires further investigation.

    Healthcare-associated infection is an important worldwide problem that could be reduced by better hand hygiene practice. However, irritant contact dermatitis of the hands as a result of repeated hand washing is a potential complication that may be preventable by the regular use of an emollient. To assess the effect of moisturizer application after repeated hand washing (15 times daily) vs. soap alone. In a double-blind, randomized study, the effect of five different moisturizers on skin barrier function was determined by assessment after repeated hand washing over a 2-week period in healthy adult volunteers. Assessments of transepidermal water loss (TEWL), epidermal hydration and a visual assessment using the Hand Eczema Severity Index (HECSI) were made at days 0, 7 and 14. In total, 132 patients were enrolled into the study. A statistically significant worsening of the clinical condition of the skin as measured by HECSI was seen from baseline to day 14 (P = 0.003) in those subjects repeatedly washing their hands with soap without subsequent application of moisturizer. No change was seen in the groups using moisturizer. Subclinical assessment of epidermal hydration as a measure of skin barrier function showed significant increases from baseline to day 14 after the use of three of the five moisturizing products (P = 0.041, 0.001 and 0.009). Three of the five moisturizers tested led to a statistically significant decrease in TEWL at day 7 of repeated hand washing. This effect was sustained for one moisturizing product at day 14 of hand washing (P = 0.044). These results support the view that the regular application of moisturizers to normal skin offers a protective effect against repeated exposure to irritants, with no evidence of a reduction in barrier efficiency allowing the easier permeation of irritant substances into the skin as has been suggested by other studies. Regular use of emollient in the healthcare environment may prevent the development of dermatitis.

  19. Spontaneous hemoperitoneum.

    Massive hemoperitoneum seen without an obvious precipitating event is rare. A 21-year-old man was seen with diffuse abdominal pain of 48 hours' duration. He had no fever, nausea, or vomiting, and most laboratory values were normal. Exploration of the abdomen revealed free intraperitoneal blood with clotting but failed to reveal a source. The patient could recall no trauma or other inciting event. The only abnormalities found during laparotomy were multiple adhesions of the omentum to the lateral abdominal wall and localization of most of the clot within the greater omentum. The author cautions that a high index of suspicion followed by laparotomy are the management tools for controlling spontaneous hemoperitoneum. Conservative management produces a high mortality rate.

    Cross-sectional. Southampton Hand Assessment Procedure (SHAP) provides function scores for hand grips (prehensile patterns) and an overall score, the index of function (IOF). The underlying equations of SHAP are not publicly available, which induces opacity. Furthermore, SHAP has been scarcely tested in prosthetic users. Issues with SHAP-IOF are discussed; an alternative scoring system, that is, linear index of function (LIF) and a weighted version (W-LIF) are presented. In LIF, task times are transformed linearly, relative to SHAP norms, and are computed into LIF-prehensile patterns (LIFPP). LIF and IOF were compared using data of 27 experienced prosthetic users. High correlation and agreement between LIF and IOF was found: LIFPP vs IOFPP ranged from r = 0.880 to r = 0.988, and W-LIF vs IOF had a correlation coefficient of r = 0.984. SHAP data of prosthetic users are valuable benchmarks for health care professionals. LIF calculations are a good and cost free alternative for IOF scores. Measurements with LIF and IOF may be considered similar, but LIF is transparent and easier to use than IOF. Clinical measurement and cross-sectional. Copyright © 2016 Hanley & Belfus.

    The foot and ankle are frequently affected in patients with rheumatoid arthritis (RA). One of the negative consequences of RA on the physical function of patients is a decrease in muscle strength. However, little is known about foot and muscle strength in this population. The aim of the study was to evaluate significant differences in foot and ankle muscle strength between patients with established RA against age and sex-matched controls using hand-held dynamometry. The maximal muscle strength of ankle plantarflexion, dorsiflexion, eversion and inversion was assessed in 14 patients with RA, mean (SD) disease duration of 22 (14.1) years, and 20 age and sex-matched control participants using hand-held dynamometry. Significant differences were observed in muscle strength between the two groups in plantarflexion (p = 0.00), eversion (p = 0.04) and inversion (p = 0.01). No significant difference was found in dorsiflexion (p > 0.05). The patients with RA displayed a significantly lower plantarflexion-dorsiflexion ratio than the control participants (p = 0.03). The results from this study showed that the RA patients displayed a significant decrease in ankle dorsiflexion, eversion and inversion when compared to the non-RA control group suggesting that foot and ankle muscle strength may be affected by the pathological processes in RA. This study is a preliminary step for the measurement of muscle impairments within the RA population.

    Full Text Available The aim of this study was to develop and validate a test for measuring the handedness of pre-school children. The newly developed test consists of 14 activities for checking various aspects of hand preference and was administered to a Viennese sample of 120 children of the ages 4 to 6.5 (18 left-handed, 17 ambidextrous and 85 right-handed. For the purpose of validation, the handedness of the children was assessed via a questionnaire given to parents, observation of the hand used to draw and testing of visual-motor skills as well as general level of development using the Viennese Development Test (WET, Kastner-Koller & Deimann, 2002. The hand preference test proved to be reliable (α=0.97. The inter-correlations of the handedness measures gathered (parent’s estimate as well as observation of drawing hand with the hand preference test substantiates the concurrent validity of the procedure. Right-handers exhibited the most pronounced hand preference; while the hand use of left-handers was significantly less lateralized. Irrespective of the direction of handedness, children with a consistent hand preference had higher total development scores than children with inconsistent use, i.e. frequent changes in hand used for a specific activity. Compared to ambidextrous and right-handed children, left-handers achieved significantly lower scores in the field of visual-motor skills. The results highlight the necessity of a reliable method for differentiated measurement of handedness as early as pre-school.

    Meat freshness is directly related to the health of consumers, and total volatile basic nitrogen (TVB-N) content is an important reference index for evaluating pork freshness. This paper attempted to measure TVB-N content for assessing pork meat freshness using a new self-developed portable and low cost detection device designed by ourselves basing on near infrared technique. The front-end part of this device was an integrated detection component containing a mini probe which was about 5cm in diameter circle. In the signal acquiring component, silicon photodiode detector was embedded in the center of light source in probe and spectral response range was 400-1100nm to receive diffuse light from pork meat surface in mini probe. The main circuits in this device included stabilized current supply circuit which was used to provide a stable power supply for each LED light source in probe and signal processing circuit which was utilized to complete signal amplification and A/D conversion, In addition, another vital function of the signal processing circuit was to analysis detection signals from mini probe in the detection component. For verifying this device performance, 58 pork samples with different freshness attributes and Multiple Linear Regression (MLR) mathematical method and ratio data processing algorithm were employed to build pork TVB-N content prediction model, and comparing with results from raw data model, the correlation coefficient of prediction and validation of TVB-N were 0.8027 and 0.7291 respectively, and the accuracy of predicting pork freshness was about 78.6%. This work demonstrates that it has the potential in nondestructive detection of TVB-N content in pork meat using this device, which can simplify related instruments design structure and reduce their development cost in future.

    Sand dune quarries are a location of common aggregate mining activity developed in coastal areas, especially in the southeast Buenos Aires province, Argentina. In this article, spontaneous plant development after extraction activity ceased was evaluated. Five areas (three quarried and two natural/conservation areas) were sampled for plant cover and composition as well as sediment characterization. Different indexes, principal component analysis, and cluster analyses were applied to compare the areas. The dominant families observed in four of the five areas were Asteraceae, Poaceae, and Cyperaceae, and most of the species are commonly found in sandy and humid soils and/or modified/anthropized ones. Percentages of plant cover increased with time because of the cessation of active aggregate extraction. Indexes and multivariate analyses showed that it was possible to distinguish quarried and natural areas based on composition and vegetation cover. The distribution of plant species among the four areas responded to the presence of mining activity, but it also responded to the topographical position and consequently the depth of the groundwater level. Besides these differences, the four areas shared many native species. The results might indicate that once the activity has ceased, quarried areas may spontaneously and quickly develop a plant community with some similarities to those present in the nonquarried areas. However, given that the extracting activity involves the removal of the soil, revegetation of this type of environment depends on the presence of natural areas in the surroundings, which can serve as a source of seeds and propagules for plant regeneration.

    Šenolt, Ladislav

    Hand osteoarthritis (OA) is a common chronic disorder causing pain and limitation of mobility of affected joints. The prevalence of hand OA increases with age and more often affects females. Clinical signs obviously do not correlate with radiographic findings - symptomatic hand OA affects approximately 26 % of adult subjects, but radiographic changes can be found in up to two thirds of females and half of males older than 55 years.Disease course differ among individual patients. Hand OA is a heterogeneous disease. Nodal hand OA is the most common subtype affecting interphalangeal joints, thumb base OA affects first carpometacarpal joint. Erosive OA represents a specific subtype of hand OA, which is associated with joint inflammation, more pain, functional limitation and erosive findings on radiographs.Treatment of OA is limited. Analgesics and nonsteroidal anti-inflammatory drugs are the only agents reducing symptoms. New insights into the pathogenesis of disease should contribute to the development of novel effective treatment of hand OA.

    Assessment of temporal and spatial relations between spontaneous mechanical activities in musculature (SMAM) at rest as revealed by diffusion-weighted imaging (DWI) and electrical muscular activities in surface EMG (sEMG). Potential influences of static and radiofrequency magnetic fields on muscular activity on sEMG measurements at rest were examined systematically. Series of diffusion-weighted stimulated echo planar imaging were recorded with concurrent sEMG measurements. Electrical activities in sEMG were analyzed by non-parametric Friedman and two-sample Kolmogorov-Smirnov test. Direct correlation of both modalities was investigated by temporal mapping of electrical activity in sEMG to DWI repetition interval. Electrical activities in sEMG and number of visible SMAMs in DWI showed a strong correlation (ρ = 0.9718). High accordance between sEMG activities and visible SMAMs in DWI in a near-surface region around sEMG electrodes was achieved. Characteristics of sEMG activities were almost similar under varying magnetic field conditions. Visible SMAMs in DWI have shown a close and direct relation to concurrent signals recorded by sEMG. MR-related magnetic fields had no significant effects on findings in sEMG. Hence, appearance of SMAMs in DWI should not be considered as imaging artifact or as effects originating from the special conditions of MR examinations. Spatial and temporal distributions of SMAMs indicate characteristics of spontaneous (microscopic) mechanical muscular action at rest. Therefore, DWI techniques should be considered as non-invasive tools for studying physiology and pathophysiology of spontaneous activities in resting muscle.

    The aim of this study was to compare skills sets during a hand-assisted and straight laparoscopic colectomy on an augmented reality simulator. Twenty-nine surgeons, assigned randomly in 2 groups, performed laparoscopic sigmoid colectomies on a simulator: group A (n = 15) performed hand-assisted then straight procedures; group B (n = 14) performed straight then hand-assisted procedures. Groups were compared according to prior laparoscopic colorectal experience, performance (time, instrument path length, and instrument velocity changes), technical skills, and operative error. Prior laparoscopic colorectal experience was similar in both groups. Both groups had better performances with the hand-assisted approach, although technical skill scores were similar between approaches. The error rate was higher with the hand-assisted approach in group A, but similar between both approaches in group B. These data define the metrics of performance for hand-assisted and straight laparoscopic colectomy on an augmented reality simulator. The improved scores with the hand-assisted approach suggest that with this simulator a hand-assisted model may be technically easier to perform, although it is associated with increased intraoperative errors.

    The objective of the study is to provide information about non disease specified outcome measures which evaluate disability in patients who have impairments in hand and upper extremity and to find the extent to which they are evaluating "disability" based on ICF hand Core Set (activity limitation and participation restriction). MEDLINE, CINAHL, GOOGLE SCHOLAR , OVID and SCIENCE DIRECT databases were systematically searched for studies on non disease specified outcome measures used to evaluate upper extremity function; only studies written in English were considered. We reviewed titles and abstracts of the identified studies to determine whether the studies met predefined eligibility criteria (eg, non disease specified out come measures used in hand injured patients). All the outcome measures which had eligibility included. After full text review ,7 non disease specified outcome measures in hand were identified. Studies were extracted, and the information retrieved from them. All the outcome measures which had incuded, were linked with ICF hand core set disability part (activity and participation). All of them only linked to 16 (42 %) components of ICF hand Core Set, which were most activity and less participation from ICF. None of the non disease specified out come measures in hand injuries cover all domains of disability from the ICF Hand Core Set.

    The introduction of 'smoke-free laws' has reduced the population's exposure to second-hand smoke (SHS), although SHS is still an issue in homes and other public places. Children are vulnerable to its health effects, and their greatest exposure occurs at home. To assess airborne nicotine concentration of the living room and children's bedroom of homes with children under 13 years of age, and to analyse factors associated with these levels. We conducted a cross-sectional study in Barcelona in 2015-2016, selecting a convenience sample from families with at least one child under 13 years of age. The sample comprised 50 families with smokers and 50 without. We measured airborne nicotine concentrations in the living room and children's bedroom, and, using a questionnaire administered to the parents, collected information about smoking habits at home. Homes without smokers showed nicotine concentrations below the limit of detection (smoked in the living room, smoking rules, the number of smokers living at home and tobacco smell. Homes with smokers present SHS in the living room and in the children's bedroom. Therefore, programmes focused on reducing children's SHS exposure are urgently needed. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Full Text Available History of present illness: A 16-year-old male with asthma was brought to the emergency department by his parents for increasing right-sided chest pain associated with cough and mild dyspnea over the past week. Albuterol inhaler did not provide relief. He denied recent trauma, fever, sweats, and chills. The patient’s vitals and oxygen saturations were stable. Physical exam revealed a tall, slender body habitus with no signs of chest wall injuries. Bilateral breath sounds were present, but slightly diminished on the right. A chest radiograph was ordered to determine the etiology of the patient’s symptoms. Significant findings: Initial chest radiograph showed a 50% right-sided pneumothorax with no mediastinal shift, which can be identified by the sharp line representing the pleural lung edge (see arrows and lack of peripheral lung markings extending to the chest wall. While difficult to accurately estimate volume from a two-dimensional image, a 2 cm pneumothorax seen on chest radiograph correlates to approximately 50% volume.1 The patient underwent insertion of a pigtail pleural drain on the right and repeat chest radiograph showed resolution of previously seen pneumothorax. Ultimately the pigtail drain was removed and chest radiograph showed clear lung fields without evidence of residual pneumothorax or pleural effusion. Discussion: Pneumothorax is characterized by air between the lungs and the chest wall.2 Spontaneous pneumothorax (SP occurs when the pneumothorax is not due to trauma or any discernable etiology. 3 SP is multifactorial and may be associated with subpleural blebs, bullae, and other connective tissue changes that predispose the lungs to leak air into the pleural space.4 SP can be further subdivided into primary (no history of underlying lung disease or secondary (history of chronic obstructive pulmonary disease, tuberculosis, cystic fibrosis, lung malignancy, etc..2 It is estimated that the incidence of SP among US pediatric

    To compare goniometric and visual assessments of angular hand joint and wrist joint positions measured by board-certified hand surgeons and certified hand therapists. We hypothesized that visual estimation would be similar to the goniometric measurement accuracy of digital and wrist joint positions. The wrist, index finger metacarpophalangeal (MCP) joint, and index finger proximal interphalangeal (PIP) joint were evaluated in different positions by 40 observers: 20 board-certified hand surgeons and 20 certified hand therapists. Each observer estimated the position of the wrist, index MCP joint, and index PIP joint of the same volunteer, who was positioned in low-profile orthoses to reproduce predetermined positions. Following visual estimation, the participants measured the same joint positions using a goniometer. The control measurement was digitally determined by a radiologist who obtained radiographs of the hand and wrist positions in each orthosis. Observers were blinded to the results of control measurements. When considering all joints at all positions, neither visual assessments nor goniometer assessments were consistently within ± 5° of the measurements obtained on control radiographs. When considering individual joints, goniometer measurements were significantly closer to control radiograph measurements than the visual assessments for all 3 PIP joint positions. There was no difference for the measurements at the wrist or for 2 of the 3 MCP joint positions. Significant differences between surgeon and therapist joint angle measurements were not observed when comparing visual and goniometer assessments to radiograph controls. Compared with radiograph measurements, neither visual nor goniometer assessment displayed high levels of accuracy. On average, visual assessment of the angular positions of the index MCP and wrist joint were as accurate as the goniometer assessment, whereas goniometer assessment of the angular position of the PIP joint was more

    Prosthetic hand users have to rely extensively on visual feedback, which seems to lead to a high conscious burden for the users, in order to manipulate their prosthetic devices. Indirect methods (electro-cutaneous, vibrotactile, auditory cues) have been used to convey information from the artificial limb to the amputee, but the usability and advantages of these feedback methods were explored mainly by looking at the performance results, not taking into account measurements of the user's mental effort, attention, and emotions. The main objective of this study was to explore the feasibility of using psycho-physiological measurements to assess cognitive effort when manipulating a robot hand with and without the usage of a sensory substitution system based on auditory feedback, and how these psycho-physiological recordings relate to temporal and grasping performance in a static setting. 10 male subjects (26+/-years old), participated in this study and were asked to come for 2 consecutive days. On the first day the experiment objective, tasks, and experiment setting was explained. Then, they completed a 30 minutes guided training. On the second day each subject was tested in 3 different modalities: Auditory Feedback only control (AF), Visual Feedback only control (VF), and Audiovisual Feedback control (AVF). For each modality they were asked to perform 10 trials. At the end of each test, the subject had to answer the NASA TLX questionnaire. Also, during the test the subject's EEG, ECG, electro-dermal activity (EDA), and respiration rate were measured. The results show that a higher mental effort is needed when the subjects rely only on their vision, and that this effort seems to be reduced when auditory feedback is added to the human-machine interaction (multimodal feedback). Furthermore, better temporal performance and better grasping performance was obtained in the audiovisual modality. The performance improvements when using auditory cues, along with vision

    Atopic dermatitis and hand eczema often impair the ability of people to work. Only a few studies have investigated whether individuals with loss-of-function filaggrin gene (FLG) mutations, who often have severe and early onset of dermatitis, experience occupational consequences. To investigate the personal consequences of having atopic dermatitis and/or hand eczema and FLG mutations. Adult Danes from the general population (n = 3247) and patients with atopic dermatitis and/or hand eczema (n = 496) were genotyped for common FLG mutations, and completed a questionnaire about skin symptoms and hand eczema. Socioeconomic variables, including disability pension, and information on work in risk occupations were retrieved from national registries. The reasons for granting disability pension were unknown. Disability pension was associated with hand eczema in the general population, especially among individuals with a history of atopic dermatitis. Moreover, self-reported hand eczema and atopic dermatitis were associated with particularly high risk of disability pension among FLG mutation carriers [odds ratio (OR) 4.02 and 95% confidence interval (CI): 1.15-14.11; and OR 6.01 and 95%CI: 2.37-15.34, respectively]. Furthermore, 60% of the FLG mutation carriers with atopic dermatitis who developed hand eczema had experienced symptoms before adulthood. In the general population, self-reported hand eczema and atopic dermatitis, particularly in individuals with a genetically impaired skin barrier, were associated with disability pension, suggesting that FLG mutations carriers with a history of atopic dermatitis and hand eczema could benefit from early attention with respect to choice of occupation. © 2017 John Wiley & Sons A/S.

  3. Hand Matters: Left-Hand Gestures Enhance Metaphor Explanation

    2017-01-01

    Research suggests that speech-accompanying gestures influence cognitive processes, but it is not clear whether the gestural benefit is specific to the gesturing hand. Two experiments tested the “(right/left) hand-specificity” hypothesis for self-oriented functions of gestures: gestures with a particular hand enhance cognitive processes involving the hemisphere contralateral to the gesturing hand. Specifically, we tested whether left-hand gestures enhance metaphor explanation, which involves right-hemispheric processing. In Experiment 1, right-handers explained metaphorical phrases (e.g., “to spill the beans,” beans represent pieces of information). Participants kept the one hand (right, left) still while they were allowed to spontaneously gesture (or not) with their other free hand (left, right). Metaphor explanations were better when participants chose to gesture when their left hand was free than when they did not. An analogous effect of gesturing was not found when their right hand was free. In Experiment 2, different right-handers performed the same metaphor explanation task but, unlike Experiment 1, they were encouraged to gesture with their left or right hand or to not gesture at all. Metaphor explanations were better when participants gestured with their left hand than when they did not gesture, but the right hand gesture condition did not significantly differ from the no-gesture condition. Furthermore, we measured participants’ mouth asymmetry during additional verbal tasks to determine individual differences in the degree of right-hemispheric involvement in speech production. The left-over-right-side mouth dominance, indicating stronger right-hemispheric involvement, positively correlated with the left-over-right-hand gestural benefit on metaphor explanation. These converging findings supported the “hand-specificity” hypothesis. PMID:28080121

    In May 2010, Switzerland introduced a heterogeneous smoking ban in the hospitality sector. While the law leaves room for exceptions in some cantons, it is comprehensive in others. This longitudinal study uses different measurement methods to examine airborne nicotine levels in hospitality venues and the level of personal exposure of non-smoking hospitality workers before and after implementation of the law. Personal exposure to second hand smoke (SHS) was measured by three different methods. We compared a passive sampler called MoNIC (Monitor of NICotine) badge, to salivary cotinine and nicotine concentration as well as questionnaire data. Badges allowed the number of passively smoked cigarettes to be estimated. They were placed at the venues as well as distributed to the participants for personal measurements. To assess personal exposure at work, a time-weighted average of the workplace badge measurements was calculated. Prior to the ban, smoke-exposed hospitality venues yielded a mean badge value of 4.48 (95%-CI: 3.7 to 5.25; n = 214) cigarette equivalents/day. At follow-up, measurements in venues that had implemented a smoking ban significantly declined to an average of 0.31 (0.17 to 0.45; n = 37) (p = 0.001). Personal badge measurements also significantly decreased from an average of 2.18 (1.31-3.05 n = 53) to 0.25 (0.13-0.36; n = 41) (p = 0.001). Spearman rank correlations between badge exposure measures and salivary measures were small to moderate (0.3 at maximum). Nicotine levels significantly decreased in all types of hospitality venues after implementation of the smoking ban. In-depth analyses demonstrated that a time-weighted average of the workplace badge measurements represented typical personal SHS exposure at work more reliably than personal exposure measures such as salivary cotinine and nicotine.

    The functional assessment of myoelectric control algorithms by persons with amputation promotes the overarching goal of the field of prosthetic limb design: to replace what was lost. However, many studies use experimental paradigms with virtual interfaces and able-bodied subjects that do not capture the challenges of a clinical implementation with an amputee population. A myoelectric control system must be robust to variable physiology, loading effects of the prosthesis on the limb, and limb position effects during dynamic tasks. Here persons with transradial limb loss performed activities of daily living using a postural controller and multi-functional prosthetic hand in order to verify that the postural controller was robust to these clinical challenges. The Southampton Hand Assessment Procedure was performed by persons with limb loss and able-bodied subjects. The results indicate that persons with limb loss and able-limbed subjects achieved the same performance and therefore that the clinical challenges were overcome. Persons with limb loss achieved 55% of physiological hand function on average. Also, the postural controller is compared to other state of the art myoelectric controllers and prosthetic hands previously tested. This work confirms that the postural controller is potentially a clinically-viable method to control myoelectric multi-functional prosthetic hands.

    Hand eczema is often a chronic, multifactorial disease. It is usually related to occupational or routine household activities. Exact etiology of the disease is difficult to determine. It may become severe enough and disabling to many of patients in course of time. An estimated 2-10% of population is likely to develop hand eczema at some point of time during life. It appears to be the most common occupational skin disease, comprising 9-35% of all occupational diseases and up to 80% or more of all occupational contact dermatitis. So, it becomes important to find the exact etiology and classification of the disease and to use the appropriate preventive and treatment measures. Despite its importance in the dermatological practice, very few Indian studies have been done till date to investigate the epidemiological trends, etiology, and treatment options for hand eczema. In this review, we tried to find the etiology, epidemiology, and available treatment modalities for chronic hand eczema patients. PMID:24891648

    Myoelectric artificial limbs can significantly advance the state of the art in prosthetics, since they can be used to control mechatronic devices through muscular activity in a way that mimics how the subjects used to activate their muscles before limb loss. However, surveys indicate that dissatisfaction with the functionality of terminal devices underlies the widespread abandonment of prostheses. We believe that one key factor to improve acceptability of prosthetic devices is to attain human likeness of prosthesis movements, a goal which is being pursued by research on social and human-robot interactions. Therefore, to reduce early abandonment of terminal devices, we propose that controllers should be designed so as to ensure effective task accomplishment in a natural fashion. In this work, we have analyzed and compared the performance of three types of myoelectric controller algorithms based on surface electromyography to control an underactuated and multi-degrees of freedom prosthetic hand, the SoftHand Pro. The goal of the present study was to identify the myoelectric algorithm that best mimics the native hand movements. As a preliminary step, we first quantified the repeatability of the SoftHand Pro finger movements and identified the electromyographic recording sites for able-bodied individuals with the highest signal-to-noise ratio from two pairs of muscles, i.e., flexor digitorum superficialis/extensor digitorum communis, and flexor carpi radialis/extensor carpi ulnaris. Able-bodied volunteers were then asked to execute reach-to-grasp movements, while electromyography signals were recorded from flexor digitorum superficialis/extensor digitorum communis as this was identified as the muscle pair characterized by high signal-to-noise ratio and intuitive control. Subsequently, we tested three myoelectric controllers that mapped electromyography signals to position of the SoftHand Pro. We found that a differential electromyography-to-position mapping ensured the

    Full Text Available To comprehend the sensorimotor control ability in diabetic hands, this study investigated the sensation, motor function and precision pinch performances derived from a pinch-holding-up activity (PHUA test of the hands of diabetic patients and healthy subjects. The precision, sensitivity and specificity of the PHUA test in the measurements of diabetic patients were also analyzed. We hypothesized that the diabetic hands would have impacts on the sensorimotor functions of the hand performances under functionally quantitative measurements. One hundred and fifty-nine patients with clinically defined diabetes mellitus (DM and 95 age- and gender-matched healthy controls were included. Semmes-Weinstein monofilament (SWM, static and moving two-point discrimination (S2PD and M2PD, maximal pinch strength and precision pinch performance tests were conducted to evaluate the sensation, motor and sensorimotor status of the recruited hands. The results showed that there were significant differences (all p<0.05 in SWM, S2PD, M2PD and maximum pinch strength between the DM and control groups. A higher force ratio in the DM patients than in the controls (p<0.001 revealed a poor ability of pinch force adjustment in the DM patients. The percentage of maximal pinch strength was also significantly different (p<0.001 between the DM and control groups. The sensitivity, specificity and area under the receiver operating characteristic curve were 0.85, 0.51, and 0.724, respectively, for the PHUA test. Statistically significant degradations in sensory and motor functions and sensorimotor control ability were observed in the hands of the diabetic patients. The PHUA test could be feasibly used as a clinical tool to determine the sensorimotor function of the hands of diabetic patients from a functional perspective.

    To study the relationship between the caregiver's perception about the patient's impairment in spontaneous speech, according to an item of four questions administered by semi-structured interview, and the patient's performance in the Brief Aphasia Evaluation (BAE). 102 right-handed patients with focal brain lesions of different types and location were examined. BAE is a valid and reliable instrument to assess aphasia. The caregiver's perception was correlated with the item of spontaneous speech, the total score and the three main factors of the BAE: Expression, Comprehension and Complementary factors. The precision (sensitivity/ specificity) about the caregiver's perception of the patient's spontaneous speech was analyzed with reference to the presence or absence of disorder, according to the professional, on the BAE item of spontaneous speech. The studied correlation was satisfactory, being greater (higher than 80%) for the following indicators: the item of spontaneous speech, the Expression factor and the total score of the scale; the correlation was a little smaller (higher than 70%) for the Comprehension and Complementary factors. Comparing two cut-off points that evaluated the precision of the caregiver's perception, satisfactory results were observed in terms of sensitivity and specificity (>70%) with likelihood ratios higher than three. By using the median as the cut-off point, more satisfactory diagnostic discriminations were obtained. Interviewing the caregiver specifically on the patient's spontaneous speech, in an abbreviated form, provides relevant information for the aphasia diagnosis.

    Manual dexterity, a prerogative of primates, is under the control of the corticospinal (CS) tract. Because 90-95% of CS axons decussate, it is assumed that this control is exerted essentially on the contralateral hand. Consistently, unilateral lesion of the hand representation in the motor cortex is followed by a complete loss of dexterity of the contralesional hand. During the months following lesion, spontaneous recovery of manual dexterity takes place to a highly variable extent across subjects, although largely incomplete. In the present study, we tested the hypothesis that after a significant postlesion period, manual performance in the ipsilesional hand is correlated with the extent of functional recovery in the contralesional hand. To this aim, ten adult macaque monkeys were subjected to permanent unilateral motor cortex lesion. Monkeys' manual performance was assessed for each hand during several months postlesion, using our standard behavioral test (modified Brinkman board task) that provides a quantitative measure of reach and grasp ability. The ipsilesional hand's performance was found to be significantly enhanced over the long term (100-300 days postlesion) in six of ten monkeys, with the six exhibiting the best, though incomplete, recovery of the contralesional hand. There was a statistically significant correlation (r = 0.932; P < 0.001) between performance in the ipsilesional hand after significant postlesion period and the extent of recovery of the contralesional hand. This observation is interpreted in terms of different possible mechanisms of recovery, dependent on the recruitment of motor areas in the lesioned and/or intact hemispheres.

    The literature has consistently shown that the Star Excursion Balance Test (SEBT) is a reliable and valid tool to anticipate the risk of lower extremity injury, assess dynamic postural control differences among groups, and assess the effectiveness of balance training programs in both healthy individuals and people with lower extremity injuries. However, there is no standard administration technique for the SEBT in research, clinical practice, or performance settings. Therefore, the purpose of this investigation was to compare six different combinations (3 different foot alignments × 2 hand positions) on the SEBT performance in those with chronic ankle instability (CAI). Repeated Measures Design. University Research Laboratory. Twenty-five university students with CAI (12 males, 13 females; age: 20.3 ± 2.4 years, height: 172.7 ± 7.4 cm, weight: 77.5 ± 15.3 kg. 25.9 ± 4.0 kg/m2) voluntarily participated in the study. Six different SEBT positions were used to assess dynamic postural control. Three foot positions: 1) Foot centered; 2) Toe fixed; and 3) Toe-heel changing and two hand placements: 1) Hands free and 2) Hands on the hips were used in this study. After 6familiarization trials for each condition, three Star Excursion Balance Test scores were recorded. Normalized reach distance (% of leg length) in the anterior, posteromedial, and posterolateral directions as well as a composite reach score quantified dynamic postural control. Both foot alignment and hand position significantly altered normalized SEBT reach distance in the anterior (p < 0.003), posteromedial (p < 0.001), posterolateral (p < 0.001), and composite reach scores (p < 0.001). Different foot alignments and hand constraints significantly altered normalized reach distances and the composite score in individuals with CAI. These results do not suggest that any combination of foot alignments and/or hand constraints is superior. However, changing the toe/heel position, while maintaining hands on the

    Full Text Available Students in introductory physics struggle with vector algebra and these challenges are often associated with contextual and representational features of the problems. Performance on problems about cross product direction is particularly poor and some research suggests that this may be primarily due to misapplied right-hand rules. However, few studies have had the resolution to explore student use of right-hand rules in detail. This study reviews literature in several disciplines, including spatial cognition, to identify ten contextual and representational problem features that are most likely to influence performance on problems requiring a right-hand rule. Two quantitative measures of performance (correctness and response time and two qualitative measures (methods used and type of errors made were used to explore the impact of these problem features on student performance. Quantitative results are consistent with expectations from the literature, but reveal that some features (such as the type of reasoning required and the physical awkwardness of using a right-hand rule have a greater impact than others (such as whether the vectors are placed together or separate. Additional insight is gained by the qualitative analysis, including identifying sources of difficulty not previously discussed in the literature and revealing that the use of supplemental methods, such as physically rotating the paper, can mitigate errors associated with certain features.

  18. Assessment of Myoelectric Controller Performance and Kinematic Behavior of a Novel Soft Synergy-inspired Robotic Hand for Prosthetic Applications

    Full Text Available Myoelectric-artificial limbs can significantly advance the state of the art in prosthetics, since they can be used to control mechatronic devices through muscular activity in a way that mimics how the subjects used to activate their muscles before limb loss. However, surveys indicate that dissatisfaction with the functionality of terminal devices underlies the widespread abandonment of prostheses. We believe that one key factor to improve acceptability of prosthetic devices is to attain human-likeness of prosthesis movements, a goal which is being pursued by research on social and human-robot interactions. Therefore, to reduce early abandonment of terminal devices, we propose that controllers should be designed such as to ensure effective task accomplishment in a natural fashion. In this work, we have analyzed and compared the performance of three types of myoelectric controller algorithms based on surface electromyography to control an under-actuated and multi-degrees of freedom prosthetic hand, the SoftHand Pro. The goal of the present study was to identify the myoelectric algorithm that best mimics the native hand movements. As a preliminary step, we first quantified the repeatability of the SoftHand Pro finger movements and identified the electromyographic recording sites for able-bodied individuals with the highest signal-to-noise ratio from two pairs of muscles, i.e. flexor digitorum superficialis/extensor digitorum communis, and flexor carpi radialis/extensor carpi ulnaris. Able-bodied volunteers were then asked to execute reach-to-grasp movements, while electromyography signals were recorded from flexor digitorum superficialis/extensor digitorum communis as this was identified as the muscle pair characterized by high signal-to-noise ratio and intuitive control. Subsequently, we tested three myoelectric controllers that mapped electromyography signals to position of the SoftHand Pro. We found that a differential electromyography

    Variability in both frontal and parietal spontaneous EEG activity, using α and β band power and θ/β and δ/β ratios, was explored in a sample of 96 healthy volunteers as a potential correlate of individual differences in spontaneous emotion regulation (SER). Following a baseline EEG recording, participants were asked to continuously rate their discomfort while looking at affective pictures, as well as for a period of time after exposure. Greater spontaneous β band power in parietal locations, lower frontal and parietal δ/β ratios, and lower parietal θ/β ratio were associated with lower ratings of discomfort after the offset of unpleasant pictures. Moreover, lower parietal δ/β ratio was also related to less time needed to recover from discomfort after exposure to aversive pictures, while only a greater frontal and parietal α band power appeared to be associated with faster recovery from discomfort induced by normative-neutral pictures. However, parietal δ/β ratio was the only predictor of both minimum discomfort ratings and time needed to downregulate following exposure to unpleasant pictures, and frontal α band power the only spontaneous EEG index that predicted variability in spontaneous down-regulation after the exposure to normative-neutral pictures. Results are discussed focusing on the utility of diverse spontaneous EEG measures in several cortical regions when capturing trait-like individual differences in emotion regulation capabilities and processes.

    Between January 2000 and July 2009, five adults who had suffered bilateral traumatic below-elbow amputations, received bilateral hand-forearm allografts performed by the Lyon team. We report the functional benefits achieved over a mean follow-up period of 7.6 years (range 4-13 years), up to December 31st, 2013. Clinical measurement is hampered by the lack of specific validated assessment tools, obliging us to use non-specific standardized evaluation means. Our assessment shows that the restoration of motion, strength, and sensibility are fair. Functional results (Carroll upper extremity function test, 400-point test, Activities of daily living) are good, as well as quality of life evaluation (RAND-36). Subjective and overall results explored with questionnaires - Disabilities of the Arm Shoulder and Hand (DASH), Hand Transplantation Score System (HTSS), are very good. Improvement was seen to continue during the first three years, and then tend to become stable. Continued efforts should be directed at designing comprehensive, condition-specific, reliable outcome measurement tools.

    Functional Extravehicular Mobility Units (EMUs) with high precision gloves are essential for the success of Extravehicular Activity (EVA). Previous research done at NASA has shown that total strength capabilities and performance are reduced when wearing a pressurized EMU. The goal of this project was to characterize the human-space suit glove interaction and assess the risk of injury during common EVA hand manipulation tasks, including pushing, pinching and gripping objects. A custom third generation sensor garment was designed to incorporate a combination of sensors, including force sensitive resistors, strain gauge sensors, and shear force sensors. The combination of sensors was used to measure the forces acting on the finger nails, finger pads, finger tips, as well as the knuckle joints. In addition to measuring the forces, data was collected on the temperature, humidity, skin conductance, and blood perfusion of the hands. Testing compared both the Phase VI and Series 4000 glove against an ungloved condition. The ungloved test was performed wearing the sensor garment only. The project outcomes identified critical landmarks that experienced higher workloads and are more likely to suffer injuries. These critical landmarks varied as a function of space suit glove and task performed. The results showed that less forces were acting on the hands while wearing the Phase VI glove as compared to wearing the Series 4000 glove. Based on our findings, the engineering division can utilize these methods for optimizing the current space suit glove and designing next generation gloves to prevent injuries and optimize hand mobility and comfort.

    To present the technique of free-hand subaxial cervical pedicle screw (CPS) placement without using intra-operative navigating devices, and to investigate the crucial factors for safe placement and avoidance of lateral pedicle wall perforation, by measuring and classifying perforations with postoperative computed tomography (CT) scan. The placement of CPS has generally been considered as technically demanding and associated with considerable lateral wall perforation rate. For surgeons without access to navigation systems, experience of safe free-hand technique for subaxial CPS placement is especially valuable. A total of 214 consecutive traumatic or degenerative patients with 1,024 CPS placement using the free-hand technique were enrolled. In the operative process, the lateral mass surface was decorticated. Then a small curette was used to identify the pedicle entrance by touching the cortical bone of the medial pedicle wall. It was crucial to keep the transverse angle and make appropriate adjustment with guidance of the resistance of the thick medial cortical bone. The hand drill should be redirected once soft tissue breach was palpated by a slim ball-tip prober. With proper trajectory, tapping, repeated palpation, the 26-30 mm screw could be placed. After the procedure, the transverse angle of CPS trajectory was measured, and perforation of the lateral wall was classified by CT scan: grade 1, perforation of pedicle wall by screw placement, with the external edge of screw deviating out of the lateral pedicle wall equal to or less than 2 mm and grade 2, critical perforation of pedicle wall by screw placement, large than 2 mm. A total of 129 screws (12.64 %) were demonstrated as lateral pedicle wall perforation, of which 101 screws (9.86 %) were classified as grade 1, whereas 28 screws (2.73 %) as grade 2. Among the segments involved, C3 showed an obviously higher perforating rate than other (P grade 2 perforation than the others. In the 28 screws of grade 2

    Purpose: To evaluate the diagnostic performance of three-dimensional (3D) MR maximum intensity projection (MIP) in the assessment of synovitis of the hand and wrist in rheumatoid arthritis (RA) compared to 3D contrast-enhanced magnetic resonance imaging (CE-MRI). Materials and methods: Twenty-five patients with RA underwent MR examinations. 3D MR MIP images were derived from the enhanced images. MR images were reviewed by two radiologists for the presence and location of synovitis of the hand and wrist. The diagnostic sensitivity, specificity and accuracy of 3D MIP were, respectively, calculated with the reference standard 3D CE-MRI. Results: In all subjects, 3D MIP images yielded directly and clearly the presence and location of synovitis with just one image. Synovitis demonstrated high signal intensity on MIP images. The k-values for the detection of articular synovitis indicated excellent interobserver agreements using 3D MIP images (k = 0.87) and CE-MR images (k = 0.91), respectively. 3D MIP demonstrated a sensitivity, specificity and accuracy of 91.07%, 98.57% and 96.0%, respectively, for the detection of synonitis. Conclusion: 3D MIP can provide a whole overview of lesion locations and a reliable diagnostic performance in the assessment of articular synovitis of the hand and wrist in patients with RA, which has potential value of clinical practice.

    [Purpose] The purpose of this study was to examine the intra- and inter-rater reliabilities of lower extremity muscle strength assessment of healthy adults using hand held dynamometer. [Subjects and Methods] A total of 55 students (19 males and 36 females) in Y University in Gyeongsangnam-do, South Korea participated in this study. Lower extremity muscle strength was measured using a hand-held dynamometer (Commander Muscle Tester, JTech, USA). Flexion and extension strengths of the hip joint, the knee joint, and the ankle joint were measured. [Results] The intra-rater reliabilities were excellent (above 0.9) for the flexion and extension strengths of the ankle, knee, and hip joints. The inter-rater reliabilities were also excellent (above 0.8) for the flexion and extension strengths of the ankle, knee, and hip joint. [Conclusion] Lower extremity muscle strength assessment using a hand-held dynamometer provided consistent results when conducted by different examiners and when measured several times. Therefore, this method is a useful way of deriving objective and quantitative measurement values.

    We conducted five studies testing whether an implicit measure of favorability toward power over universalism values predicts spontaneous prejudice and discrimination. Studies 1 (N = 192) and 2 (N = 86) examined correlations between spontaneous favorability toward power (vs. universalism) values, achievement (vs. benevolence) values, and a spontaneous measure of prejudice toward ethnic minorities. Study 3 (N = 159) tested whether conditioning participants to associate power values with positive adjectives and universalism values with negative adjectives (or inversely) affects spontaneous prejudice. Study 4 (N = 95) tested whether decision bias toward female handball players could be predicted by spontaneous attitude toward power (vs. universalism) values. Study 5 (N = 123) examined correlations between spontaneous attitude toward power (vs. universalism) values, spontaneous importance toward power (vs. universalism) values, and spontaneous prejudice toward Black African people. Spontaneous positivity toward power (vs. universalism) values was associated with spontaneous negativity toward minorities and predicted gender bias in a decision task, whereas the explicit measures did not. These results indicate that the implicit assessment of evaluative responses attached to human values helps to model value-attitude-behavior relations. © 2016 The Authors.

    Selecting and maintaining an engaging and challenging training difficulty level in robot-assisted stroke rehabilitation remains an open challenge. Despite the ability of robotic systems to provide objective and accurate measures of function and performance, the selection and adaptation of exercise difficulty levels is typically left to the experience of the supervising therapist. We introduce a patient-tailored and adaptive robot-assisted therapy concept to optimally challenge patients from the very first session and throughout therapy progress. The concept is evaluated within a four-week pilot study in six subacute stroke patients performing robot-assisted rehabilitation of hand function. Robotic assessments of both motor and sensory impairments of hand function conducted prior to the therapy are used to adjust exercise parameters and customize difficulty levels. During therapy progression, an automated routine adapts difficulty levels from session to session to maintain patients' performance around a target level of 70%, to optimally balance motivation and challenge. Robotic assessments suggested large differences in patients' sensorimotor abilities that are not captured by clinical assessments. Exercise customization based on these assessments resulted in an average initial exercise performance around 70% (62% ± 20%, mean ± std), which was maintained throughout the course of the therapy (64% ± 21%). Patients showed reduction in both motor and sensory impairments compared to baseline as measured by clinical and robotic assessments. The progress in difficulty levels correlated with improvements in a clinical impairment scale (Fugl-Meyer Assessment) (r s = 0.70), suggesting that the proposed therapy was effective at reducing sensorimotor impairment. Initial robotic assessments combined with progressive difficulty adaptation have the potential to automatically tailor robot-assisted rehabilitation to the individual patient. This results in optimal challenge and

    Increasingly, implants in the region of hand joints and the wrist represent an alternative for the treatment of post-traumatic, inflamed, or degenerative joint damage. The diversity of hand functions also results in varied solutions, which are effective in their stability, mobility, and distraction. Different materials are necessary for this, and they require subtile radiological control. The native X-ray represents the substantial method to observe migration of the implants. Each interface between titanium, ceramic, zirconium, pyrocarbon, and silicon to the bone has to be assessed differently in order to obtain a relevant statement. The finger joints and to a limited extent the wrist represent the artificial joints with limited alternative therapy. Other implants in the hand should only be applied after strict indication and patient compliance, as arthrodesis and resection arthroplasty have shown very good long-term results. (orig.)

    A quantitative human risk assessment of chloroxylenol was conducted for liquid hand and dishwashing soap products used by consumers and health-care workers. The toxicological data for chloroxylenol indicate lack of genotoxicity, no evidence of carcinogenicity, and minimal systemic toxicity. No observed adverse effect levels (NOAEL) were established from chronic toxicity studies, specifically a carcinogenicity study that found no cancer excess (18 mg/kg-day) and studies of developmental and reproductive toxicity (100 mg/kg-day). Exposure to chloroxylenol for adults and children was estimated for two types of rinse-off cleaning products, one liquid hand soap, and two dishwashing products. The identified NOAELs were used together with exposure estimates to derive margin of exposure (MOE) estimates for chloroxylenol (i.e., estimates of exposure over NOAELs). These estimates were designed with conservative assumptions and likely overestimate exposure and risk (i.e., highest frequency, 100% dermal penetration). The resulting MOEs ranged from 178 to over 100, 000, 000 indicating negligibly small potential for harm related to consumer or health-care worker exposure to chloroxylenol in liquid soaps used in dish washing and hand washing.

No TCCA procedure for objectively-assessed outcome (OAO measures exists. Furthermore, no official German version of the Canadian Chedoke Arm and Hand Activity Inventory (CAHAI is available. Methods An eight-step for TCCA procedure for OAO was developed (TCCA-OAO based on the existing TCCA procedure for patient-reported outcomes. The TCCA-OAO procedure was applied to develop a German version of the CAHAI (CAHAI-G. Inter-rater reliability of the CAHAI-G was determined through video rating of CAHAI-G. Validity evaluation of the CAHAI-G was assessed using the Chedoke-McMaster Stroke Assessment (CMSA. All ratings were performed by trained, independent raters. In a cross-sectional study, patients were tested within 31 hours after the initial CAHAI-G scoring, for their motor function level using the subscales for arm and hand of the CMSA. Inpatients and outpatients of the occupational therapy department who experienced a cerebrovascular accident or an intracerebral haemorrhage were included. Results Performance of 23 patients (mean age 69.4, SD 12.9; six females; mean time since stroke onset: 1.5 years, SD 2.5 years have been assessed. A high inter-rater reliability was calculated with ICCs for 4 CAHAI-G versions (13, 9, 8, 7 items ranging between r = 0.96 and r = 0.99 (p Conclusions The TCCA-OAO procedure was validated regarding its feasibility and applicability for objectively-assessed outcome measures. The resulting German CAHAI can be used as a valid and reliable assessment for bilateral upper limb performance in ADL in patients after stroke.

The findings presented in this paper are based on the results of the ALPS (Assessment and Learning in Practice Settings CETL (Centre for Excellence in Teaching and Learning programme, a 5 year examination of the use of mobile technology for interprofessional, formative, work-based assessment among health and social care students. Analysing the results of multiple focus groups across a number of health and social care professions we found that learner engagement with self-directed mobile assessment is dependent on internal and external factors. In this paper we explore the internal factors, namely that of learner goal, confidence and stage of self-direction (Grow, 1991.

    Background Standardised translation and cross-cultural adaptation (TCCA) procedures are vital to describe language translation, cultural adaptation, and to evaluate quality factors of transformed outcome measures. No TCCA procedure for objectively-assessed outcome (OAO) measures exists. Furthermore, no official German version of the Canadian Chedoke Arm and Hand Activity Inventory (CAHAI) is available. Methods An eight-step for TCCA procedure for OAO was developed (TCCA-OAO) based on the existing TCCA procedure for patient-reported outcomes. The TCCA-OAO procedure was applied to develop a German version of the CAHAI (CAHAI-G). Inter-rater reliability of the CAHAI-G was determined through video rating of CAHAI-G. Validity evaluation of the CAHAI-G was assessed using the Chedoke-McMaster Stroke Assessment (CMSA). All ratings were performed by trained, independent raters. In a cross-sectional study, patients were tested within 31 hours after the initial CAHAI-G scoring, for their motor function level using the subscales for arm and hand of the CMSA. Inpatients and outpatients of the occupational therapy department who experienced a cerebrovascular accident or an intracerebral haemorrhage were included. Results Performance of 23 patients (mean age 69.4, SD 12.9; six females; mean time since stroke onset: 1.5 years, SD 2.5 years) have been assessed. A high inter-rater reliability was calculated with ICCs for 4 CAHAI-G versions (13, 9, 8, 7 items) ranging between r = 0.96 and r = 0.99 (p < 0.001). Correlation between the CAHAI-G and CMSA subscales for hand and arm was r = 0.74 (p < 0.001) and r = 0.67 (p < 0.001) respectively. Internal consistency of the CAHAI-G for all four versions ranged between α = 0.974 and α = 0.979. Conclusions The TCCA-OAO procedure was validated regarding its feasibility and applicability for objectively-assessed outcome measures. The resulting German CAHAI can be used as a valid and reliable assessment for bilateral upper limb performance in

    Air nicotine monitoring is a well-known procedure for estimation of exposure to second hand smoke. Few research studies were realized in Romania to evaluate environmental tobacco smoke (ETS) exposure of humans in different public places. The levels of airborne nicotine from environmental tobacco smoke and urinary cotinine and nicotine levels of some subjects were analyzed. In order to better implement/enforce the European legislation regarding the interdiction of smoking in the public places the national authorities need a rapid and reliable analytical method to quickly asses the state of the pollution with cigarette smoke of these populated areas. The nicotine concentration in the air from different types of public buildings was determined. The median concentration of nicotine in the air from 32 pubs where the smoking was allowed was 590 ng · L(-1), comparing with the pubs where the smoking was not permitted (22 locations) where the median concentration of nicotine was only 32 ng · L(-1). Similarly, the median concentration of nicotine in restaurants where the smoking was allowed (23 locations) was 510 ng · L(-1), in comparison with the restaurants where the smoking was prohibited (11 places) where the median value was 19 ng · L(-1). The lowest concentrations of nicotine were found in high schools (8 locations, median concentration 7.4 ng · L(-1)), universities (5 locations, 23 ng · L(-1)) and hospitals (6 locations, 16 ng · L(-1)). The method was validated and gave good linearity, precision, accuracy and limit of detection. The buildings included hospitals, high schools, universities, pubs and restaurants. The presence of air nicotine was recorded in all buildings studied. The highest median levels of air nicotine were found in pubs and restaurants. The presence of air nicotine in indoor public buildings indicates weak implementation of the smoke free law in Romania.

    Full Text Available To investigate whether sensorimotor control of the hand could be an outcome indicator after carpal tunnel release (CTR, this work examined changes in the results of patients' manual tactile test (MTT, pinch-holding-up activity (PHUA, two-point discrimination (2PD and Semmes-Weinstein monofilament (SWM tests. Participants included 30 predominantly sensory neuropathy CTS patients, as confirmed by a nerve conduction study. The MTT, precision pinch performance in PHUA and traditional sensibility (2PD and SWM tests were used to examine different aspects of sensory status at the time-points of two weeks before operation and one month post-operation, with a single-blind design. The results showed significant improvements in the sensory function as detected by the 2PD and SWM tests (p0.5, p<0.01 are better than that of two-point discrimination test (effect size<0.5, p<0.001. However, pinch strength saw a decline compared to baseline with a moderate effect sizes (effect size = 0.7, p<0.001. This cohort study found that the MTT and PHUA test can both meet all the statistical criteria with regard to assessing treatment outcomes for patients with CTS. In addition, the results of this work provide clinicians with the information that the sensorimotor functions of the hands, as assessed by MTT and PHUA, are responsive to clinical changes due to CTR.

    A 29-year-old female presented with complaints of fever and productive cough of three weeks duration. Pulmonary tuberculosis was diagnosed bacteriologically and she was prescribed antituberculosis drugs. During follow-up she developed massive pneumothorax, for which patient refused surgical management and was managed conservatively. After six months there was complete spontaneous resolution of pneumothorax. The unusual presentation and unexpected outcome prompted us to report this case. PMID:22937428

    With spinal anaesthesia various methods may be used to assess the block to touch. We wished to compare the levels of block assessed using a non-standardised, assessor-dependent touch stimulus with those assessed when the same stimulus was applied in a standardised manner independent of the assessor. In a double-blind, randomised study the levels of block to touch were assessed by two investigators, one using a hand-held Neurotip tester pin and the other using the same tester pin mounted in a spring loaded system (Neuropen). Both the testing device and the order of testing were randomised between the two observers. The dermatomes were marked on patients' torsos before surgery. Whole group data analysis in a Bland Altman plot demonstrated a median difference of 0 dermatomes between the two methods: the 5th, 25th, 75th, and 95th centiles of agreement being -2, -1, +1, and +2 dermatomes respectively. There were occasional wide differences in levels of block to touch with the Neuropen varying between seven dermatomes rostral to and four dermatomes caudal to the Neurotip. These differences were short-lived and did not affect clinical management. When comparing two very similar touch stimuli, one standardised and user-independent and one non-standardised, we observed occasional wide but short lived differences in the assessed levels of block to touch. Although these differences did not affect clinical management, whether more dissimilar touch testing methods might affect clinical management remains to be seen.

    In a third year geoscience elective for BSc majors, we adapted several active f2f learning strategies for an equivalent fully online version of the course. In particular, we converted a hands-on laboratory including analysis and interpretation of hand-specimens, sketching results and peer-to-peer discussion of scientific implications. This study compares learning outcomes in both formats and describes resources that make engaging, effective and efficient learning experiences for large classes in an asynchronous online environment. Our two hypotheses are: 1) a hands-on geology lab exercise can be converted for efficient fully online use without sacrificing feedback and assessment opportunities; 2) students find either the f2f or DE versions equally effective and enjoyable as learning experiences. Key components are an authentic context, interactive resources including sketching, strategies that enable efficient assessment and feedback on solo and group work, and asynchronous yet productive interaction with peers. Students in the f2f class handle real rock and fossil specimens, work with peers in the lab and classroom, and deliver most results including annotated figures on paper. DE students complete identical tasks using interactive high resolution figures and videos of specimens. Solo work is first delivered for automated assessment and feedback, then students engage asynchronously in small groups to improve results and discuss implications. Chronostratigraphy and other interpretations are sketched on prepared template images using a simple open-source sketching app that ensures equal access and consistent results that are efficient to assess by peers and instructors. Learning outcomes based on subsequent quizzes, sketches, and lab results (paper for f2f students and automated data entry for DE students), show that f2f and online students demonstrate knowledge and scientific interpretations of comparable quality. Effective engagement and group work are

    Abortion is associated with moderate to high risk of psychological problems such as depression, use of alcohol or marijuana, anxiety, depression and suicidal behaviours. The increased risk of depression after spontaneous abortion in Asian populations has not been clearly established. Only a few studies have explored the relationship between grief and depression after abortion. A study was conducted to assess the prevalence and risk factors of depressive disorder and complicated grief among women 6-10 weeks after spontaneous abortion and compare the risk of depression with pregnant women attending an antenatal clinic. Spontaneous abortion group consisted of women diagnosed with spontaneous abortion by a Consultant Obstetrician. Women with confirmed or suspected induced abortion were excluded. The comparison group consisted of randomly selected pregnant, females attending the antenatal clinics of the two hospitals. Diagnosis of depressive disorder was made according to ICD-10 clinical criteria based on a structured clinical interview. This assessment was conducted in both groups. The severity of depressive symptoms were assessed using the Patients Health Questionnaire (PHQ-9). Grief was assessed using the Perinatal Grief Scale which was administered to the women who had experienced spontaneous abortion. The sample consisted of 137 women in each group. The spontaneous abortion group (mean age 30.39 years (SD = 6.38) were significantly older than the comparison group (mean age 28.79 years (SD = 6.26)). There were more females with ≥10 years of education in the spontaneous abortion group (n = 54; SD = 39.4) compared to the comparison group (n = 37; SD = 27.0). The prevalence of depression in the spontaneous abortion group was 18.6 % (95 CI, 11.51-25.77). The prevalence of depression in the comparison group was 9.5 % (95 CI, 4.52-14.46). Of the 64 women fulfilling criteria for grief, 17 (26.6 %) also fulfilled criteria for a depressive episode. The relative risk of

    There is a popular belief that the lunar cycle influences spontaneous delivery in both humans and cattle. To assess this relationship, we investigated the synodic distribution of spontaneous deliveries in domestic Holstein cows. We used retrospective data from 428 spontaneous, full-term deliveries within a three-year period derived from the calving records of a private farm in Hokkaido, Japan. Spontaneous birth frequency increased uniformly from the new moon to the full moon phase and decreased until the waning crescent phase. There was a statistically significant peak between the waxing gibbous and full moon phases compared with those between the last quarter and the waning crescent. These changes were clearly observed in deliveries among multiparous cows, whereas they were not evident in deliveries among nulliparous cows. These data suggest the utility of dairy cows as models for bio-meteorological studies, and indicate that monitoring lunar phases may facilitate comprehensive understanding of parturition.

    The present research investigates whether spontaneous trait inferences occur under conditions characteristic of social media and networking sites: nonextreme, ostensibly self-generated content, simultaneous presentation of multiple cues, and self-paced browsing. We used an established measure of trait inferences (false recognition paradigm) and a direct assessment of impressions. Without being asked to do so, participants spontaneously formed impressions of people whose status updates they saw. Our results suggest that trait inferences occurred from nonextreme self-generated content, which is commonly found in social media updates (Experiment 1) and when nine status updates from different people were presented in parallel (Experiment 2). Although inferences did occur during free browsing, the results suggest that participants did not necessarily associate the traits with the corresponding status update authors (Experiment 3). Overall, the findings suggest that spontaneous trait inferences occur on social media. We discuss implications for online communication and research on spontaneous trait inferences.

    Balakrishnan, Vimala; Yeow, Paul H. P.

    The effect of hand anthropometry on Short Message Service (SMS) satisfaction was investigated using structured questionnaire interviews with 110 subjects, aged between 17-25 years old. Hand size was measured to assess its effect on mobile phone design factors satisfaction whereas thumb circumference and length were measured for keypad design factors. Small hand-sized subjects were found to be more satisfied with mobile phone dimensions than large hand-sized subjects. Thumb circumference significantly affects users` satisfaction towards key size and space between keys whereas thumb length significantly affects keypad layout satisfaction. Both thumb circumference and length significantly correlate negatively with the corresponding keypad design factors. Results confirm that hand anthropometry do affect users messaging satisfaction. These findings should prove useful to mobile phone designers who could look into the possibility of designing customized mobile phones that cater to large hand and thumb sized users, so as to increase their subjective satisfaction.

    Although contrast agents have become indispensable tools in magnetic resonance and their safe and effective use the foundation of many essential diagnostic procedures, only limited summary information on their utilization and pharmacovigilance is available to the community. After voluntary access to the manufacturer spontaneous adverse event database, we assessed the available data for gadopentetate dimeglumine. Gadopentetate dimeglumine (Gd-DTPA, Magnevist; Berlex/Schering AG, Berlin, Germany) became commercially available in 1988 and is currently marketed in 101 countries. Using the manufacturer's continuous and cumulative database on product distribution and spontaneous adverse event (AE) reporting, we categorized AEs and assessed their cumulative occurrence after 10, 20, and 45 million applications that occurred in 1993, 1997, and 2002, respectively. Furthermore, we reviewed publications in Medline to assess prevalence of the 4 most common MR contrast agents in the indexed literature. Gd-DTPA has been used in more than 45 million magnetic resonance imaging procedures since 1988 and is currently used globally in more than 5 million applications annually. The broadest category of spontaneously reported AEs, subjective symptoms, occurs in less than 0.01% of procedures. Within the total AEs reported, the distribution of serious and nonserious reports was 9.3% and 90.7%, respectively. The rates of AE reporting have changed over time, with increased rates in the second reporting period (1993 to 1997), followed by substantially lower rates in subsequent years. AE reporting rates are the most comprehensive data available; however, there will always be some underestimation of the true event rates. Although no substantial differences were noted among major age groups, substantial differences in reporting frequency were found among regions, with the United States reporting nearly twice as many AEs as Europe in the postmarketing phase. The postmarketing utilization and

    Full Text Available Pyometra is the accumulation of purulent material in the uterine cavity. Its reported incidence is 0.01–0.5% in gynecologic patients; however, as far as elderly patients are concerned, its incidence is 13.6% [3]. The most common cause of pyometra is malignant diseases of genital tract and the consequences of their treatment (radiotherapy. Other causes are benign tumors like leiomyoma, endometrial polyps, senile cervicitis, cervical occlusion after surgery, puerperal infections, and congenital cervical anomalies. Spontaneous rupture of the uterus is an extremely rare complication of pyometra. To our knowledge, only 21 cases of spontaneous perforation of pyometra have been reported in English literature since 1980. This paper reports an additional case of spontaneous uterine rupture.

    In the present study, we aim to share our clinical experience in patients with spontaneous splenic rupture. Splenic rupture without trauma is known as spontaneous splenic rupture. The major problems in the management of spontaneous splenic rupture are missed or delayed diagnosis due to the lack of trauma in most cases. The records of all patients, who were admitted to Cerrahpaşa Medical Faculty, Istanbul University, were retrospectively reviewed from January 2000 to March 2013. Twelve patients were admitted to the emergency department and they were diagnosed with spontaneous splenic rupture. The mean age was 47.6 years. All patients had complaints of abdominal pain. The mean hematocrit value was 22%. Radiologic assessment revealed hemoperitoneum and/or subcapsular hematoma in 8 patients while splenic abscess was diagnosed in 2 patients. Eleven patients underwent splenectomy whereas one was managed conservatively. The most common cause of spontaneous splenic rupture was determined to be use of anticoagulants. Etiology was considered to be idiopathic in 1 patient. Two patients died in the postoperative period. Although rare, spontaneous splenic rupture must be suspected in emergency patients who have used especially anticoagulants and antiaggregants and who have had no recent history of trauma. One of the important causes of mortality is missed or delayed diagnosis.

    Isolated spontaneous dissection of renal arteries or its branches are extremely rare. Most cases of renal artery dissection are associated with underlying pathology of the renal arteries. We report a case of spontaneous dissection of the left main renal artery and infarction of the left kidney with positive antiphospholipid antibody. Extensive work up of the patient including imaging studies confirmed the diagnosis of SRAD. Antiphospholipid antibodies may have a role in the pathogenesis of arterial dissection by causing endothelial dysfunction. This is a first literature report.

    Full Text Available Spontaneous atraumatic mediastinal hematomas are rare. We present a case of a previously fit and well middle-aged lady who presented with acute breathlessness and an increasing neck swelling and spontaneous neck bruising. On plain chest radiograph, widening of the mediastinum was noted. The bruising was later confirmed to be secondary to mediastinal hematoma. This life-threatening diagnostic conundrum was managed conservatively with a multidisciplinary team approach involving upper gastrointestinal and thoracic surgeons, gastroenterologists, radiologists, intensivists, and hematologists along with a variety of diagnostic modalities. A review of literature is also presented to help surgeons manage such challenging and complicated cases.

    Full Text Available Esta revisão de literatura aborda aspectos metodológicos e fisiológicos da dinamometria manual. A dinamometria manual é um teste funcional do músculo esquelético que vem recebendo uma crescente atenção de clínicos e pesquisadores da área de saúde nos últimos anos. Recentemente, tem merecido atenção como indicador do estado nutricional, particularmente para pacientes internados. Dentre os principais fatores que influenciam esta medida, destacam-se o sexo, a idade, a estatura, a massa corporal e a mão dominante dos indivíduos. Os resultados desta revisão demonstram ainda que diversos outros fatores, relacionados ao protocolo de aferição, como a posição do indivíduo, o tipo de instrumento utilizado, o número de aferições realizadas, o intervalo de descanso entre as aferições, a presença de estímulo verbal e de um pré-teste, também podem influenciar os valores alcançados por um indivíduo em uma avaliação da dinamometria manual. Dessa forma, é importante que um protocolo de aferição padronizado seja desenvolvido, para que se obtenham medidas válidas de dinamometria manual. Ainda são escassos os estudos que propõem valores de referência para a dinamometria manual e a literatura ainda se ressente de valores de referência baseados em dados obtidos a partir de amostras de base populacional.This paper reviews the methodological and physiological aspects of hand grip strength measurement.

    Full Text Available The use of haptic devices in the rehabilitation of impaired limbs has become rather popular, given the proven effectiveness in promoting recovery. In a standard framework, such devices are used in rehabilitation centers, where patients interact with virtual tasks, presented on a screen. To track their sessions, kinematic/dynamic parameters or performance scores are recorded. However, as Internet access is now available at almost every home and in order to reduce the hospitalization time of the patient, the idea of doing rehabilitation at home is gaining wide consent. Medical care programs can be synchronized with the home rehabilitation device; patient data can be sent to the central server that could redirect to the therapist laptop (tele-healthcare. The controversial issue is that the recorded data do not actually represent the clinical conditions of the patients according to the medical assessment scales, forcing them to frequently undergo clinical tests at the hospital. To respond to this demand, we propose the use of a bilateral master/slave haptic system that could allow the clinician, who interacts with the master, to assess remotely and in real time the clinical conditions of the patient that uses the home rehabilitation device as the slave. In this paper, we describe a proof of concept to highlight the main issues of such an application, limited to one degree of freedom, and to the measure of the stiffness and range of motion of the hand.

    Spontaneous ultraweak photon (biophoton) emissions from hands are measured for healthy subjects. The data provide basic reference information for diagnostic application of biophoton emission. The overall average of biophoton emissions from the hands is 226.4 +/- 14.3 counts per second. The asymmetry of the biophoton emission rates between the left and the right hands could be significant for both western and oriental diagnosis.

    2015-10-01

    The aim of the study was to characterize the extent of indication bias resulting from the excessive use of NSAIDs on the days preceding a spontaneous abortion to relieve pain. We used data from a retrospective cohort study assessing the risk for spontaneous abortions following exposure to NSAIDs. Three definitions of exposure for cases of spontaneous abortions were compared, from the first day of pregnancy until the day of spontaneous abortion and until 3 and 2 days before a spontaneous abortion. Statistical analysis was performed using multivariate time programmed Cox regression. A sharp increase was observed in the dispensation of indomethacin, diclofenac and naproxen, and a milder increase was found in the use of ibuprofen during the week before a spontaneous abortion. Non- selective COX inhibitors in general and specifically diclofenac and indomethacin were found to be associated with spontaneous abortions when the exposure period was defined until the day of spontaneous abortion (hazard ratio (HR) 1.15, 95% confidence interval (CI) 1.04, 1.28; HR 1.31, 95% CI 1.08, 1.59 and HR 3.33, 95% CI 2.09, 5.29, respectively). The effect disappears by excluding exposures occurring on the day before the spontaneous abortion for non-selective COX inhibitors and on the last week before the spontaneous abortion for indomethacin. In general, decreasing HRs were found with the exclusion of exposures occurring on the days immediately before the spontaneous abortion. The increased use of NSAIDs during the last few days that preceded a spontaneous abortion to relieve pain associated with the miscarriage could bias studies assessing the association between exposure to NSAIDs and spontaneous abortions. © 2015 The British Pharmacological Society.

    Other than trauma, rib fracture can occur spontaneously due to a severe cough or sneeze. In this study, patients with spontaneous rib fractures were analyzed according to age, sex, underlying pathology, treatment, and complications. Twelve patients who presented between February 2009 and February 2011 with spontaneous rib fracture were reviewed retrospectively. The patients' data were evaluated according to anamnesis, physical examination, and chest radiographs. The ages of the patients ranged from 34 to 77 years (mean 55.91 ± 12.20 years), and 7 (58.4%) were male. All patients had severe cough and chest pain. The fractures were most frequently between 4th and 9th ribs; multiple rib fractures were detected in 5 (41.7%) patients. Eight (66.7%) patients had chronic obstructive pulmonary disease, 2 (16.7%) had bronchial asthma, and 2 (16.7%) had osteoporosis. Bone densitometry revealed a high risk of bone fracture in all patients. Patients with chronic obstructive pulmonary disease or bronchial asthma had been treated with high-dose steroids for over a year. Spontaneous rib fracture due to severe cough may occur in patients with osteoporosis, chronic obstructive pulmonary disease, or bronchial asthma, receiving long-term steroid therapy. If these patients have severe chest pain, chest radiography should be performed to check for bone lesions. © The Author(s) 2015.

    Spontaneous bacterial peritonitis occurs most commonly in cirrhotic patients with ascites. Pathogens get into the circulation by intestinal translocation and colonize in peritoneal fluid. Diagnosis of spontaneous bacterial peritonitis is based on elevated polymorphonuclear leukocyte count in the ascites (>0,25 G/L). Ascites culture is often negative but aids to get information about antibiotic sensitivity in positive cases. Treatment in stable patient can be intravenous then orally administrated ciprofloxacin or amoxicillin/clavulanic acid, while in severe cases intravenous III. generation cephalosporin. Nosocomial spontaneous bacterial peritonitis often caused by Gram-positive bacteria and multi-resistant pathogens can also be expected thus carbapenem should be the choice of the empiric treatment. Antibiotic prophylaxis should be considered. Norfloxacin is used most commonly, but changes are expected due to increase in quinolone resistance. As a primary prophylaxis, a short-term antibiotic treatment is recommended after gastrointestinal bleeding for 5 days, while long-term prophylaxis is for patients with low ascites protein, and advanced disease (400 mg/day). Secondary prophylaxis is recommended for all patients recovered from spontaneous bacterial peritonitis. Due to increasing antibiotic use of antibiotics prophylaxis is debated to some degree. Orv.

    Full Text Available The heat transfer process from a 6.4 Watt blue light flexible phototherapy mattress to a human hand has been studied. The intended use of the mattress is the provision of neonatal jaundice phototherapy during Kangaroo Mother Care (KMC or skin-to-skin care. The heat transfer process has been studied with temperature and heat flow sensors inside an expanded- polystyrene spheroid 25mm of thickness where the phototherapy mattress’s non emitting surface is in contact and folded around the hand while the light radiates outwards, to the polystyrene spheroid. The effective thermal capacitance of the phototherapy mattress was calculated as 3.4 J/oK, the mattress-to-hand thermal conductance was found to be 0.25 W/oC, the maximum temperature gradient between the mattress and the palm of the hand was 10oC and the maximum power absorbed by the hand, 2.5W. The palm of the hand skin-to-core temperature gradient was 0.5oC. It is expected that when used in KMC only one half of the hand skin surface would be in contact with the phototherapy mattress so that the effective thermal conductance to the hand in this conditions would be 0.125 W/oC. Further study is suggested to include sweating effect of the hand.

  16. Prosody in the hands of the speaker

    Guellaï, Bahia; Langus, Alan; Nespor, Marina

    2014-01-01

    In everyday life, speech is accompanied by gestures. In the present study, two experiments tested the possibility that spontaneous gestures accompanying speech carry prosodic information. Experiment 1 showed that gestures provide prosodic information, as adults are able to perceive the congruency between low-pass filtered—thus unintelligible—speech and the gestures of the speaker. Experiment 2 shows that in the case of ambiguous sentences (i.e., sentences with two alternative meanings depending on their prosody) mismatched prosody and gestures lead participants to choose more often the meaning signaled by gestures. Our results demonstrate that the prosody that characterizes speech is not a modality specific phenomenon: it is also perceived in the spontaneous gestures that accompany speech. We draw the conclusion that spontaneous gestures and speech form a single communication system where the suprasegmental aspects of spoken language are mapped to the motor-programs responsible for the production of both speech sounds and hand gestures.

    2003-01-01

    Because hand eczema and fragrance allergy are common both among patients and in the general population, simultaneous occurrence by chance must be expected. Fragrances are ubiquitous and a part of many domestic and occupational products intended for hand exposure. The present review is based...... fragrance allergy and hand eczema. In future studies, a more detailed exposure assessment is needed, combined with patch test studies among patients with hand eczema tested with relevant fragrance allergens, as well as experimental control exposure studies to specific fragrance allergens on the hands....... As exposures to fragrances on the hands are often simultaneous exposures to irritants, this combined exposure approach needs to be considered....

    2012-06-01

    Smokers' knowledge of the risks of second-hand smoke (SHS) and the role this plays in implementing behaviours to reduce the SHS exposure of others have not been thoroughly explored. Mass media health promotion is used to promote behaviour change partly by providing information on the consequences of behaviour. In England, between 2003 and 2006, frequent mass media campaigns highlighted the toxicity of SHS. To examine peoples' knowledge of SHS-related illnesses in England over time, identify the determinants of good knowledge and to assess its importance in predicting SHS-protective behaviours. Statistical analysis of repeat cross-sectional data (1996-2008) from the Omnibus Survey to explore the trends and determinants of knowledge of SHS-related illnesses and the determinants of SHS-protective behaviours. Only 40% of smokers had 'good' knowledge of SHS-related illnesses compared with 65% of never smokers. Knowledge increased markedly when frequent SHS-related mass media campaigns (2003-06) ran, compared with earlier years (1996-2002). Smokers with better knowledge were more likely to have smoke-free homes [odds ratio (OR): 1.10, 1.04-1.16] and abstain from smoking in a room with children (OR: 1.11, 1.09-1.14). The low levels of knowledge of some SHS-related conditions, especially among smokers, and the relationship between knowledge and SHS-protective behaviours, suggest that greater efforts to educate smokers about the risks associated with SHS are worthwhile.

  1. Health Impact Assessment for Second-Hand Smoke Exposure in Germany—Quantifying Estimates for Ischaemic Heart Diseases, COPD, and Stroke

    2016-02-01

    Full Text Available Evidence of the adverse health effects attributable to second-hand smoke (SHS exposure is available. This study aims to quantify the impact of SHS exposure on ischaemic heart diseases (IHD, chronic obstructive pulmonary diseases (COPD, and stroke in Germany. Therefore, this study estimated and forecasted the morbidity for the three outcomes in the German population. Furthermore, a health impact assessment was performed using DYNAMO-HIA, which is a generic software tool applying a Markov model. Overall 687,254 IHD cases, 231,973 COPD cases, and 288,015 stroke cases were estimated to be attributable to SHS exposure in Germany for 2014. Under the assumption that the population prevalence of these diseases and the prevalence of SHS exposure remain constant, the total number of cases will increase due to demographic aging. Assuming a total eradication of SHS exposure beginning in 2014 leads to an estimated reduction of 50% in cases, compared to the reference scenario in 2040 for all three diseases. The results highlight the relevance of SHS exposure because it affects several chronic disease conditions and has a major impact on the population’s health. Therefore, public health campaigns to protect non-smokers are urgently needed.

  3. [Augmented spontaneous breathing].

    1996-09-01

    Impaired pulmonary gas exchange can result from lung parenchymal failure inducing oxygenation deficiency and fatigue of the respiratory muscles, which is characterized by hypercapnia or a combination of both mechanisms. Contractility of and coordination between the diaphragm and the thoracoabdominal respiratory muscles predominantly determine the efficiency of spontaneous breathing. Sepsis, cardiac failure, malnutrition or acute changes of the load conditions may induce fatigue of the respiratory muscles. Augmentation of spontaneous breathing is not only achieved by the application of different technical principles or devices; it also has to improve perfusion, metabolism, load conditions and contractility of the respiratory muscles. Intermittent mandatory ventilation (IMV) allows spontaneous breathing of the patient and augments alveolar ventilation by periodically applying positive airway pressure tidal volumes, which are generated by the respirator. Potential advantages include lower mean airway pressure (PAW), as compared with controlled mechanical ventilation, and improved haemodynamics. Suboptimal IMV systems may impose increased work and oxygen cost of breathing, fatigue of the respiratory muscles and CO2 retention. During pressure support ventilation (PSV), inspiratory alterations of PAW or gas flow (trigger) are detected by the respirator, which delivers a gas flow to maintain PAW at a fixed value (usually 5-20 cm H2O) during inspiration. PSV may be combined with other modalities of respiratory therapy such as IMV or CPAP. Claimed advantages of PSV include decreased effort of breathing, reduced systemic and respiratory muscle consumption of oxygen, prophylaxis of diaphragmatic fatigue and an improved extubation rate after prolonged periods of mechanical ventilation. Minimum alveolar ventilation is not guaranteed during PSV; thus, close observation of the patient is mandatory to avoid serious respiratory complications. Continuous positive airway pressure

    A topic much considered in research on acalculia was its relationship with aphasia. Far less attention has been given to the natural course of acalculia. In this retrospective study, we examined the relationship between aphasia and acalculia in an unselected series of 98 left-brain-damaged patients and the spontaneous recovery from acalculia in 92 acalculic patients with follow-up. There was a significant association between aphasia and acalculia although 19 participants exhibited aphasia with no acalculia and six acalculia with no aphasia. We observed significant improvement between a first examination carried out between 1 and 5 months post-onset and a second examination carried out between 3 and 11 months later (mean: 5 months). The mechanisms of spontaneous recovery are discussed.

    Full Text Available Spontaneous perforation is a very rare complication of pyometra. The clinical findings of perforated pyometra are similar to perforation of the gastrointestinal tract and other causes of acute abdomen. In most cases, a correct and definite diagnosis can be made only by laparotomy. We report two cases of diffuse peritonitis caused by spontaneous perforated pyometra. The first case is a 78-year-old woman with abdominal pain for which laparotomy was performed because of suspected incarcerated hernia. The second case is a 61-year-old woman with abdominal pain for which laparotomy was performed because of symptoms of peritonitis. At laparotomy of both cases, 1 liter of pus with the source of uterine was found in the abdominal cavity. The ruptured uterine is also detected. More investigations revealed no malignancy as the reason of the pyometra.

    Spontaneous pneumothorax is rare in childhood. Before 12 years of age the main underlying pathologies are asthma, cystic malformations, post infectious bullae, and infectious pneumoniae. After 12 years of age it is mainly associated with cystic fibrosis and constitutional slim morphology. Symptoms vary according to the extent of lung collapse and the diagnosis is confirmed on chest X rays. In mildly symptomatic pneumothorax, spontaneous resolution is achieved within few days. When cardiorespiratory difficulties are present, mechanical evacuation of air from the pleural cavity is necessary through a tube drainage maintained until complete pulmonary reexpansion. Surgical treatment is indicated in case of persisting air leakage after one week of efficient drainage, large cystic malformation or post infectious bullae, recurring or bilateral pneumothorax.

    Exposure to second-hand tobacco smoke is preventable, yet common. This study assessed relationships between maternal exposure to second-hand tobacco smoke and adverse pregnancy outcomes. We measured cotinine (a biomarker of tobacco smoke) in urine from 921 women undergoing assisted reproductive technologies (ARTs) between 1994 and 1998. We also collected information on self-reported exposure to second-hand smoke at home or at work, in addition to parental smoking during the women's childhood. In crude analysis, creatinine-adjusted cotinine levels were associated with a slight decrease in implantation rate among non-smoking women (11.1% in the lowest cotinine quintile versus 8.2% in the highest cotinine quintile; P=0.13). However, in multivariate logistic regression, cotinine levels above the median were not associated with failed fertilization, failed implantation or spontaneous abortion, nor was there evidence of a dose-response relationship among cotinine quintiles. After excluding women in couples diagnosed with male factor infertility, there were increased odds of having a spontaneous abortion among non-smoking women who reported that both parents smoked while they were children growing up compared with women reporting that neither parent smoked [adjusted odds ratio (OR) = 4.35; 95% confidence interval (CI) = 1.04-18.1]. Female exposure to second-hand smoke as a child or in utero may be associated with an increased risk of spontaneous abortion in adulthood. However, this may be a chance finding due to multiple comparisons. Similar associations should be explored in additional studies with more refined estimates of childhood and in utero exposure to tobacco smoke.

    2001-11-01

    To report a new complication associated with pegging hydroxyapatite orbital implants: spontaneous loosening of the sleeve. Retrospective noncomparative case series. Four patients ranging in age from 38 to 60 years participated. Four patients are described who successfully received hydroxyapatite orbital implants with motility peg and sleeve systems. In each case spontaneous loosening of the sleeve developed. Clinical and surgical outcomes were assessed. Three patients had the peg and sleeve removed followed by repair of the peg hole, and one patient had placement of a larger diameter peg and sleeve system. All patients did well. Problems have been reported when motility coupling pegs are used with hydroxyapatite orbital implants. Spontaneous loosening of the sleeve is another potential complication to discuss with the patient considering an implant peg.

  13. Mapping cortical hand motor representation using TMS: A method to assess brain plasticity and a surrogate marker for recovery of function after stroke?

    Lüdemann-Podubecká, Jitka; Nowak, Dennis Alexander

    2016-10-01

    Stroke is associated with reorganization within motor areas of both hemispheres. Mapping the cortical hand motor representation using transcranial magnetic stimulation may help to understand the relationship between motor cortex reorganization and motor recovery of the affected hand after stroke. A standardized review of the pertinent literature was performed. We identified 20 trials, which analyzed the relationship between the extent and/or location of cortical hand motor representation using transcranial magnetic stimulation and motor function and recovery of the affected hand. Several correlations were found between cortical reorganization and measures of hand motor impairment and recovery. A better understanding of the relationships between the extent and location of cortical hand motor representation and the motor impairment and motor recovery of the affected hand after stroke may contribute to a targeted use of non-invasive brain stimulation protocols. In the future motor mapping may help to guide brain stimulation techniques to the most effective motor area in an affected individual. Copyright © 2016 Elsevier Ltd. All rights reserved.

    The present paper aims to perform a screening of native plants growing in Kettara mine-Marrakech (Southern Morocco) for its phytoremediation. Plants and soil samples were collected and analyzed for Pb, Zn, Cu and Cd concentrations at several sites in the mine. The results showed that the soil in the vicinity of Kettara mine is deficient in major elements and contain toxic levels of metals. Spontaneously growing native plants were botanically identified and then classified into 21 species and 14 families. Significant difference was observed among the average concentrations of four heavy metals (Pb, Zn, Cu and Cd) in plants (p ≤ 0.05). Six plants of 21 species namely Hammada scoparia (Pomel) Iljin, Hirschfeldia incana (L.) Lagreze-Fossat, Lamarckia aurea (L.) Moench, Calendula algeriensis Boiss. & Reuter, Aizoon hispanicum L. and Melilotus sulcata Desf. were considered as the best-performing specimens due to their high ability to accumulate multiple metals in their shoots and roots without sustaining toxicity. This was confirmed by the transfer factors generally higher than 1. Using the most common criteria to classify the hyperaccumulator plants, these species can be classified as new accumulator plants of many heavy metals and be potentially used as remediation tools of metal-contaminated sites.

    In football, ice-hockey, and track and field, injuries have been predicted, and hip- and knee-strength deficits quantified using hand-held dynamometry (HHD). However, systematic bias exists when testers of different sex and strength perform the measurements. Belt-fixation of the dynamometer may resolve this. The aim of the present study was therefore to examine the inter-tester reliability concerning strength assessments of isometric hip abduction, adduction, flexion, extension and knee-flexion strength, using HHD with external belt-fixation. Twenty-one healthy athletes (6 women), 30 (8.6) (mean (SD)) years of age, were included. Two physiotherapy students (1 female and 1 male) performed all the measurements after careful instruction and procedure training. Isometric hip abduction, adduction, flexion, extension, and knee-flexion strength were tested. The tester-order and hip-action order were randomised. No systematic between-tester differences (bias) were observed for any of the hip or knee actions. The intra-class correlation coefficients (ICC 2.1) ranged from 0.76 to 0.95. Furthermore, standard errors of measurement in per cent (SEM %) ranged from 5 to 11 %, and minimal detectable change in per cent (MDC %) from 14 to 29 % for the different hip and knee actions. The present study shows that isometric hip- and knee-strength measurements have acceptable inter-tester reliability at the group level, when testing strong individuals, using HHD with belt-fixation. This procedure is therefore perfectly suited for the evaluation and monitoring of strong athletes with hip, groin and hamstring injuries, some of the most common and troublesome injuries in sports.

    Continuous spontaneous alternation behavior (SAB) in a Y-maze is used for evaluating working memory in rodents. Here, the design of an automated Y-maze equipped with three infrared optocouplers per arm, and commanded by a reduced instruction set computer (RISC) microcontroller is described. The software was devised for recording only true entries and exits to the arms. Experimental settings are programmed via a keyboard with three buttons and a display. The sequence of arm entries and the time spent in each arm and the neutral zone (NZ) are saved as a text file in a non-volatile memory for later transfer to a USB flash memory. Data files are analyzed with a program developed under LabVIEW® environment, and the results are exported to an Excel® spreadsheet file. Variables measured are: latency to exit the starting arm, sequence and number of arm entries, number of alternations, alternation percentage, and cumulative times spent in each arm and NZ. The automated Y-maze accurately detected the SAB decrease produced in rats by the muscarinic antagonist trihexyphenidyl, and its reversal by caffeine, having 100 % concordance with the alternation percentages calculated by two trained observers who independently watched videos of the same experiments. Although the values of time spent in the arms and NZ measured by the automated system had small discrepancies with those calculated by the observers, Bland-Altman analysis showed 95 % concordance in three pairs of comparisons, while in one it was 90 %, indicating that this system is a reliable and inexpensive alternative for the study of continuous SAB in rodents.

    Full Text Available Objective: The hand is one of the most frequently affected body parts by burn injuries with a rate of 80% among all burn wounds. Early and effective treatment ensures the best chance of survival as well as a good functional prognosis. The aim of this study was to determine the epidemiology, variation, relationship between etiology and hospital stay, clinical features, and management of hand burns. Material and Methods: This retrospective study was conducted the University of Health Sciences; Şişli Hamidiye Etfal Application and Research Center, Departmant of Plastic, Reconstructive and Aesthetic Surgery and the Intensive Burn Care Unit between April 2009 and April 2014. Burns were assessed based on etiology, anatomical location, percentage of total body surface area affected, and depth of injury. Treatment was categorized as conservative, elective operative, or urgent operative. Results: In the study period, 788 patients were admitted to our Burn Unit. Of these, 240 were females (30.5% and 548 were males (69.5%. The most common type of burn injury in this study was thermal injury (695 cases; 88.2%, followed by electrical injury (67 cases; 8.5%, and chemical, frictional or unknown injuries (26 cases; 3.3%. Majority (more than 85% of the patients had second-degree burns, and some had third-degree burns. Conclusions: Burns commonly affect the hands, and many functional problems may develop if appropriate basic treatments are neglected. The best treatment for burns is prevention. Appropriate indoor arrangement and simple but effective measures that can be taken at home can significantly reduce burn trauma exposure.

    We investigated whether spontaneous antigravity limbs movements in very low birth weight preterm infants were insufficient compared to those in term infants. The relationship between the quality of general movements (GMs) and antigravity limbs movements was also examined. Preterm infants with very low birth weight without central nervous system disorders nor severe respiration disorders, and healthy term infants were recruited. The infants were set in a supine position. The distance between both hands and between both feet, and the height of both hands and feet from the floor were recorded at 1-3 corrected months for preterm infants, and at 1-3 months for term infants by a 3D motion capture system. The measurements were adjusted for body proportions. GMs in preterm and term infants were assessed similarly. Thirteen preterm and 15 term infants completed the study. In preterm infants, the distance between both hands and between both feet were longer, and the height of both hands and feet were lower than those in term infants in all measurements. In term infants, the height of both hands and feet increased as they developed, but no change was observed in preterm infants. In preterm infants with abnormal GMs, the distance between both hands was longer, and the height of both hands and feet was lower than that in those with normal GMs. There were no such differences between preterm infants with normal GMs and term infants with normal GMs. Antigravity limbs movements in preterm infants within the first 3 month of corrected age were insufficient compared with those in term infants. Furthermore, no improvement with development was observed in preterm infants. In addition, preterm infants with abnormal GMs showed worse antigravity limbs movements than preterm and term infants with normal GMs. The preterm infants with normal GMs could behave similar to the full term infants.

    Approximately 205 million pregnancies occur each year in the worldwide. On the other hand, Spontaneous abortion has been reported in 15-20% of all diagnosed pregnancies. The most common cause of spontaneous abortion is chromosomal abnormalities of the embryo. Robertsonian translocation carriers specially 21-14 are the most common balanced rearrangement among the carrier couples with the history of spontaneous abortion. In order to search for balanced chromosomal rearrangement and cytogenetic disorders, 10 members of related family with consanguinity marriage with the history of recurrent miscarriage were assessed. Cytogenetic evaluation on the basis G-banding technique at high resolution was performed in 3 couples and their related family with the history of idiopathic RSA in order to postulate any balanced chromosomal rearrangement. six members of them appeared with robertsonian balanced translocation between chromosome No.21 to No. 14 with the karyotype of 45, XX, t (14, 21) and 45, XY, t (14, 21), which this results are in agreement with several similar works which claimed that the risk of spontaneous abortion in couples with balanced chromosomal rearrangements is higher compared with general population. Considering to results of present study, it seems as if the cytogenetic analysis of couples with the history of recurrent abortions should be suggested compulsory to estimate the probable presence of any chromosomal rearrangement. This offer wills valuable information for genetic consulting.

    Full Text Available The Stratum corneum is a principal protector against physical, chemical, biological aggression and water loss in human skin. The repeated use of alcohol-based hand sanitizers might result in dryness and aggression. This study aims to evaluate the impact of a four week-long regular use of an alcohol-based gel hand sanitizer on skin hydration on the epidermal ‘barrier’ function using a kinetic model to quantify TEWL desorption curves following a POST test. A group of 13 female (19.7 ± 1.0 years old washed one of their hands for 29 consecutive days with a commercially available ethanol-based gel sanitizer. TEWL, superficial hydration (SH and deep hydration (DH were measured on days 1, 8, 15, 22 and 29, while a continuous TEWL recording following a 24 hour POST was made on days 1, 15 and 29 on a second skin area. No differences were found for the control hand throughout the study. For the test hand an increase of TEWL was found between days 1 and 8, as well as an increase of SH and DH between days 1 and 22. No significant differences were found for the kinetic parameters. These results suggest that the frequent use of the sanitizer gel might alter the skin barrier function.

    Performing proper hand hygiene and surgical hand antisepsis is essential to reducing the rates of health care-associated infections, including surgical site infections. The updated AORN "Guideline for hand hygiene" provides guidance on hand hygiene and surgical hand antisepsis, the wearing of fingernail polish and artificial nails, proper skin care to prevent dermatitis, the wearing of jewelry, hand hygiene product selection, and quality assurance and performance improvement considerations. This article focuses on key points of the guideline to help perioperative personnel make informed decisions about hand hygiene and surgical hand antisepsis. The key points address the necessity of keeping fingernails and skin healthy, not wearing jewelry on the hands or wrists in the perioperative area, properly performing hand hygiene and surgical hand antisepsis, and involving patients and visitors in hand hygiene initiatives. Perioperative RNs should review the complete guideline for additional information and for guidance when writing and updating policies and procedures. Copyright © 2017 AORN, Inc.

  9. New method for assessing hand disinfection shows that pre-operative alcohol/chlorhexidine rub is as effective as a traditional surgical scrub.

    Science.gov (United States)

    Howard, J D; Jowett, C; Faoagali, J; McKenzie, B

    2014-10-01

    Several studies have shown that rubbing hands with an alcohol/chlorhexidine solution provides equivalent microbial decontamination to a conventional surgical scrub using aqueous chlorhexidine. However, the authors believe that these studies have methodological flaws that limit their applicability to the operating theatre environment. As such, a method was developed to compare products in an everyday operating theatre environment using working operating theatre personnel. To determine whether or not an alcohol/chlorhexidine rub is as efficacious as a traditional surgical scrub using a novel method. Bacterial counts at baseline were collected from 20 anaesthetists using the glove juice method. Subsequently, with sequential exchange of sterile gloves, one hand underwent a 3-min scrub using 4% aqueous chlorhexidine, and the other hand underwent a 60-s rub with a 70% isopropyl alcohol/0.5% chlorhexidine solution. The residual bacterial count was collected for each hand after 30 min using the glove juice method. These counts were converted to log10 values to compare the baseline counts of right and left hands, and efficacy between the treatment groups. Mean [± standard deviation (SD)] bacterial counts at baseline were (log10) 4.42 ± 0.81 for left hands and 4.64 ± 0.60 for right hands (P > 0.05). The mean (± SD) reduction from baseline was (log10) 1.45 ± 0.50 for 4% chlorhexidine and 2.01 ± 0.98 for alcohol/chlorhexidine (P > 0.05). An alcohol/chlorhexidine hand rub was found to be as efficacious as a traditional scrub after 30 min; this study differs from previous work as it was undertaken in a population of practising anaesthetists in their working environment. The McKenzie method allows baseline and study evaluations to be performed contemporaneously on the same individual. Each subject was his/her own control. This method offers a more clinically relevant way to compare disinfectant solutions than standard methods. Crown Copyright © 2014. Published by Elsevier

  10. Spontaneous sensorimotor coupling with multipart music.

    Science.gov (United States)

    Hurley, Brian K; Martens, Peter A; Janata, Petr

    2014-08-01

    Music often evokes spontaneous movements in listeners that are synchronized with the music, a phenomenon that has been characterized as being in "the groove." However, the musical factors that contribute to listeners' initiation of stimulus-coupled action remain unclear. Evidence suggests that newly appearing objects in auditory scenes orient listeners' attention, and that in multipart music, newly appearing instrument or voice parts can engage listeners' attention and elicit arousal. We posit that attentional engagement with music can influence listeners' spontaneous stimulus-coupled movement. Here, 2 experiments-involving participants with and without musical training-tested the effect of staggering instrument entrances across time and varying the number of concurrent instrument parts within novel multipart music on listeners' engagement with the music, as assessed by spontaneous sensorimotor behavior and self-reports. Experiment 1 assessed listeners' moment-to-moment ratings of perceived groove, and Experiment 2 examined their spontaneous tapping and head movements. We found that, for both musically trained and untrained participants, music with more instruments led to higher ratings of perceived groove, and that music with staggered instrument entrances elicited both increased sensorimotor coupling and increased reports of perceived groove. Although untrained participants were more likely to rate music as higher in groove, trained participants showed greater propensity for tapping along, and they did so more accurately. The quality of synchronization of head movements with the music, however, did not differ as a function of training. Our results shed new light on the relationship between complex musical scenes, attention, and spontaneous sensorimotor behavior.

  11. Imaging of early spontaneous osteonecrosis and osteoarthritis of the knee

    In this paper, the available of MRI in diagnosis on early spontaneous osteonecrosis and osteoarthritis was investigated. Subjects were 5 cases (5 knees) with spontaneous osteonecrosis (stage 1 in Koshino`s classification) and 96 cases (104 knees) in osteoarthritis who were more than 50 years old. Patients with an early spontaneous osteonecrosis were elderly females and had night pain and severe spontaneous pain. On MRI, lesions of all cases were clearly detected in early stage. On the other hand, only 47 of 104 knees (45%) were detected in patients with osteoarthritis, and mirror lesions at shank sides were detected in 45 of 47 knees. These results suggest that it is possible to diagnose early spontaneous osteonecrosis from osteoarthritis by MRI image with the clue to mirror lesion at shank sides, incidence, stage, etc. On the diagnosis of early spontaneous osteonecrosis, MRI image should be performed as soon as possible if a patient was older, had no anamnesis of lesions, and no changes by the X-ray radiography in spite of severe pain of the knee joints.

  12. Spying on spontaneous combustion

    Energy Technology Data Exchange (ETDEWEB)

    1994-11-01

    The British Coal Technical Services and Research Executive (TSRE) has carried out a project to investigate potential applications of fibre optic based distributed temperature sensing (DTS) technology within a mining environment. The objective was to determine whether DTS could identify and locate spontaneous combustion earlier than conventional systems. The trials took place in a British mine from April to September 1992 and from August to November 1993 using a commercially available system from York Sensors Ltd. Results indicate that DTS is capable of very sensitive temperature monitoring, revealing sub-degree thermal trends resulting from various activities and local heatings. DTS has several prospective mining applications, e.g. monitoring known hot spots, investigating ventilation and heat flow through mine workings. The trials show that the system can be installed, calibrated, operated and maintained by relatively inexperienced personnel. 1 photo.

  13. Impaired hand size estimation in CRPS.

    Science.gov (United States)

    Peltz, Elena; Seifert, Frank; Lanz, Stefan; Müller, Rüdiger; Maihöfner, Christian

    2011-10-01

    A triad of clinical symptoms, ie, autonomic, motor and sensory dysfunctions, characterizes complex regional pain syndromes (CRPS). Sensory dysfunction comprises sensory loss or spontaneous and stimulus-evoked pain. Furthermore, a disturbance in the body schema may occur. In the present study, patients with CRPS of the upper extremity and healthy controls estimated their hand sizes on the basis of expanded or compressed schematic drawings of hands. In patients with CRPS we found an impairment in accurate hand size estimation; patients estimated their own CRPS-affected hand to be larger than it actually was when measured objectively. Moreover, overestimation correlated significantly with disease duration, neglect score, and increase of two-point-discrimination-thresholds (TPDT) compared to the unaffected hand and to control subjects' estimations. In line with previous functional imaging studies in CRPS patients demonstrating changes in central somatotopic maps, we suggest an involvement of the central nervous system in this disruption of the body schema. Potential cortical areas may be the primary somatosensory and posterior parietal cortices, which have been proposed to play a critical role in integrating visuospatial information. CRPS patients perceive their affected hand to be bigger than it is. The magnitude of this overestimation correlates with disease duration, decreased tactile thresholds, and neglect-score. Suggesting a disrupted body schema as the source of this impairment, our findings corroborate the current assumption of a CNS involvement in CRPS. Copyright © 2011 American Pain Society.

    2009-01-01

    Full Text Available AIMS: Spontaneous ruptured hepatocellular adenoma (SRHA is a rare life-threatening condition that may require surgical treatment to control hemorrhaging and also stabilize the patient. We report a series of emergency surgeries performed at our institution for this condition. METHODS: We reviewed medical records and radiology files of 28 patients (from 1989 to 2006 with a proven diagnosis of hepatocellular adenoma (HA. Three (10.7% of 28 patients had spontaneous ruptured hepatocellular adenoma, two of which were associated with intrahepatic hemorrhage while one had intraperitoneal bleeding. Two patients were female and one was male. Both female patients had a background history of oral contraceptive use. Sudden abdominal pain associated with hemodynamic instability occurred in all patients who suffered from spontaneous ruptured hepatocellular adenoma. The mean age was 41.6 years old. The preoperative assessment included liver function tests, ultrasonography and computed tomography. RESULTS: The surgical approaches were as follows: right hemihepatectomy for controlling intraperitoneal bleeding, and right extended hepatectomy and non-anatomic resection of the liver for intrahepatic hemorrhage. There were no deaths, and the postoperative complications were bile leakage and wound infection (re-operation, as well as intraperitoneal abscess (re-operation and pleural effusion. CONCLUSION: Spontaneous ruptured hepatocellular adenoma may be treated by surgery for controlling hemorrhages and stabilizing the patient, and the decision to operate depends upon both the patient's condition and the expertise of the surgical team.

    2012-11-01

    Nylon-reinforced silver sodium carboxymethylcellulose (AQUACEL(®) Ag BURN) dressings were developed to be pliable and conforming for the management of partial-thickness burns. This study evaluated the AQUACEL(®) Ag BURN glove for the management of hand burns. This 21-day, phase II, prospective, non-comparative study included 23 patients with partial-thickness hand burn of at least two fingers. The AQUACEL(®) Ag BURN glove was applied to one hand and could remain in place up to 21 days until clinically indicated to change the glove. Dressings were evaluated 1, 2, 4, 6, 8, 14, and 21 days after initial application. Safety was the primary study endpoint. Sixteen (70%) hand burns re-epithelialized fully over a mean of 15.6 days. Initial application was easy/very easy for 20 (87%) patients. Mean time for initial dressing application was 5.4 min. At final evaluation, most patients gave ratings of excellent/good for conformability (91%), overall glove performance (74%), and appropriateness of sizes (83%). Mean pain score from 0 (none) to 10 (worst imaginable) was 3.43 at baseline; during the study, mean scores were 1.15 at rest and 2.29 during movement. Of 61 glove removals, most (72%) were easy/very easy, and 12% had fallen off. Adverse events (wound site or elsewhere) occurred in 15 (65%) patients. Treatment-related adverse events were wound pain (17%), maceration (9%), and stiff fingers (4%). The AQUACEL(®) Ag BURN glove was well tolerated in the management of partial-thickness hand burn. Many patients used only one glove. When glove changes were required, they were usually quick and easy. Copyright © 2012 Elsevier Ltd and ISBI. All rights reserved.

  16. [Integration of Injured Hands].

    Science.gov (United States)

    Winkel, Reiner

    2017-02-01

    Any injury of a hand more or less disintegrates the injured hand. The rehabilitation of an alienated hand is prolonged. How can the alienation of the own but injured hand and the involuntary and unconscious inhibition of its perception and use be diagnosed, explained, avoided and designated? Medical observations and interviews with patients and therapists on the occasion of rehabilitation of hand injuries resulted in the development of a new concept of biopsychosocial integrating rehabilitation and a creative hand therapy with the objective of integrating injured and alienated hands. The inhibition of the gesture of thinking has been the most revealing sign for the diagnosis of a disintegration of an injured hand. Explanation: The involuntary inhibition to recognize and use an injured hand causes and implicates the alienation of the rested hand. Information by hand surgeons and hand therapists. Creative hand therapy guides the attention to complex and pleasing activities. In complex disintegrations after hand injuries the hand as well as the person need help. Designation: Hypotheses: Posttraumatic Proportionate Regional Disintegration while the tissues heal. Posttraumatic Complex Regional Disintegration, if the disintegration overruns the healing of tissues or if the person suffers. The Complex Regional Pain Syndrome is distinguished as a rare exception of a biopsychosocial disintegration. Posttraumatic regional disintegration seems to be proportionate while the tissues are healing. If the mentioned sensations of the patients and the visible signs of disintegration persist, the disorder spreads onto the biopsychosocial unit of the person. This disorder of hand and person may be designated as a complex disorder. The impact of a proportionate posttraumatic disintegration as well as the formation and exacerbation of a complex posttraumatic disintegration may be prevented by the facilitation of the integration of an injured hand. Scientific prove is needed for: the

    The relationship between serum testosterone level and nonverbal intelligence was studied in right-handed young adults with regard to handedness. Hand preference was assessed by the Edinburgh Handedness Inventory. Hand skill was measured by a peg moving task. Serum testosterone level was determined using tritium-marked-radioimmunoassay. Visual-spatial performance (nonverbal intelligence) was measured by Cattell's Culture Fair Intelligence Test. In men with consistent right-hand preference (GSs: 80 to 100), IQ was found to be positively linearly related to serum testosterone, which exhibited two regression lines belonging to low and high difference in skill between hands. In females with consistent right-handedness, there was a negative linear correlation between IQ and serum testosterone, which also exhibited two different regression lines according to difference in skill between hands. In males with moderate right-hand preference (GSs 50 to 75), IQ was found to be positively linearly related to serum testosterone, exhibiting two different (same slopes) regression lines according to difference in skill between hands. In females with moderate right-hand preference, IQ first increased and then decreased with serum testosterone, exhibiting a quadratic relationship. These results suggested that serum testosterone in young adults may be associated with visual-spatial performance depending upon sex, hand preference, and hand skill.

    2017-09-01

    The Michigan Hand Outcomes Questionnaire has been widely used for nearly 20 years to assess patients with a variety of hand and upper extremity conditions. However, normative data have not previously been collected, limiting interpretation. The Michigan Hand Outcomes Questionnaire was administered to 579 participants recruited from the general population. In addition, participants were asked to identify any problem affecting their hand(s), including trauma, hand disease/condition, systemic illness, or nonspecific symptoms. Comorbidities and demographic data were also collected. Total Michigan Hand Outcomes Questionnaire score for healthy individuals was indicative of generally good hand function (95.2; 95 percent CI, 94.3 to 96.1). Individuals with unilateral trauma scored for their affected hand (90.3; 95 percent CI, 87.9 to 92.6) lower than their healthy hand (mean difference, 5.7; 95 percent CI, 3.2 to 8.3). For individuals with and without hand trauma, total Michigan Hand Outcomes Questionnaire score decreased with increasing number of comorbidities. Many of the differences in Michigan Hand Outcomes Questionnaire score between the problem hand and unaffected hand were smaller than the minimal clinically important difference of 3.0 to 23.0 for known abnormalities of the hand and upper extremity. These normative data provide appropriate baseline information for individuals with and without underlying hand conditions. Most notably, these findings suggest that individuals with a unilateral problem establish new subnormative values for both their affected and unaffected hands. These data will encourage an appropriate understanding of the results of future studies using the Michigan Hand Outcomes Questionnaire.

    Full Text Available Purpose. Hand infections are common, usually resulting from an untreated injury. In this retrospective study, we report on hand infection cases needing surgical drainage in order to assess patient demographics, causation of infection, clinical course, and clinical management.Methods. Medical records of patients presenting with hand infections, excluding post-surgical infections, treated with incision and debridement over a one-year period were reviewed. Patient demographics; past medical history; infection site(s and causation; intervals between onset of infection, hospital admission, surgical intervention and days of hospitalization; gram stains and cultures; choice of antibiotics; complications; and outcomes were reviewed.Results. Most infections were caused by laceration and the most common site of infection was the palm or dorsum of the hand. Mean length of hospitalization was 6 days. Methicillin-resistant Staphylococcus aureus, beta-hemolytic Streptococcus and methicillin-susceptible Staphylococcus aureus were the most commonly cultured microorganisms. Cephalosporins, clindamycin, amoxicillin/clavulanate, penicillin, vancomycin, and trimethoprim/sulfamethoxazole were major antibiotic choices. Amputations and contracture were the primary complications.Conclusions. Surgery along with medical management were key to treatment and most soft tissue infections resolved without further complications. With prompt and appropriate care, most hand infection patients can achieve full resolution of their infection.

  4. The Avocado Hand

    LENUS (Irish Health Repository)

    Rahmani, G

    2017-11-01

    Accidental self-inflicted knife injuries to digits are a common cause of tendon and nerve injury requiring hand surgery. There has been an apparent increase in avocado related hand injuries. Classically, the patients hold the avocado in their non-dominant hand while using a knife to cut\\/peel the fruit with their dominant hand. The mechanism of injury is usually a stabbing injury to the non-dominant hand as the knife slips past the stone, through the soft avocado fruit. Despite their apparent increased incidence, we could not find any cases in the literature which describe the “avocado hand”. We present a case of a 32-year-old woman who sustained a significant hand injury while preparing an avocado. She required exploration and repair of a digital nerve under regional anaesthesia and has since made a full recovery.

    2007-01-01

    Patients with end stage renal disease (ESRD) have many musculoskeletal abnormalities, including hand dysfunction. The Sollerman test evaluates hand grip function in daily activities. The relationships between Sollerman test (dominant hand) with Duruoz's Hand Index (DHI), Health Assessment Questionnaire (HAQ), and Beck Depression Inventory (BDI) tests have not been investigated previously. The aims of this study are to evaluate hand grip function using the Sollerman test in hemodialysis (HD) patients, correlate this test with other measures evaluating hand function or psychosocial status, and investigate factors that can affect Sollerman test. One-hundred twenty HD patients (64 male, 56 female, mean age 51 +/- 1.4 years, mean duration of HD therapy 5.3 +/- 3.7 years) were included in this study. The HAQ, DHI, and BDI scores were determined by standard techniques. All patients underwent the Jamar grip test and Sollerman test for the dominant (D) and non-dominant hand (ND). We found a positive correlation between Sollerman test (dominant hand) with Sollerman test-ND, Jamar-D, and Jamar-ND tests. There were negative correlations between Sollerman test with age, HAQ, BDI, and DHI tests. The relationships between Sollerman test (dominant hand) with DHI, HAQ, and BDI tests have not been investigated previously. This study showed the correlations between the Sollerman test (dominant hand) and other tests (either positive or negative). Psychosocial problems can affect hand functions.

    Spontaneous intracranial hypotension (SIH) is an uncommon but increasingly recognized syndrome. Orthostatic headache with typical findings on magnetic resonance imaging (MRI) are the key to diagnosis. Delayed diagnosis of this condition may subject patients to unnecessary procedures and prolong morbidity. We describe six patients with SIH and outline the important clinical and neuroimaging findings. They were all relatively young, 20-54 years old, with clearly orthostatic headache, minimal neurological signs (only abducent nerve paresis in two) and diffuse pachymeningeal gadolinium enhancement on brain MRI, while two of them presented subdural hygromas. Spinal MRI was helpful in detecting a cervical cerebrospinal fluid leak in three patients and dilatation of the vertebral venous plexus with extradural fluid collection in another. Conservative management resulted in rapid resolution of symptoms in five patients (10 days-3 weeks) and in one who developed cerebral venous sinus thrombosis, the condition resolved in 2 months. However, this rapid clinical improvement was not accompanied by an analogous regression of the brain MR findings that persisted on a longer follow-up. Along with recent literature data, our patients further point out that SIH, to be correctly diagnosed, necessitates increased alertness by the attending physician, in the evaluation of headaches.

    2012-07-01

    Full Text Available In this case report, we discussed a case of spontaneous intracapsular tonsillar haemorrhage appearing as a tumor medial to the left palatine tonsil and clinging to the tonsillar tissue with a pedicle. The patient was a 30 years old healthy pregnant woman. She had a growing sensation of a lump in her oropharynx and dysphagia in the past three months. She had no history of acute and chronic tonsillitis or trauma. On examination, a mobile brown mass with a 2 cm diameter having a small pedicle at the upper pole of the left palatine tonsil was seen. Other laboratory results were normal. The mass was excised under general anesthesia. Histological evaluation revealed tonsillar intracapsular bleeding with lymphoepi-thelial tissue and acute hemorrhagic fields bounded by a capsule. A postpartum tonsillectomy was planned for our patient. Tonsillectomy must be performed to patients followed up with this diagnosis in order to differentiate between dyspha-gia, risks of bleeding and aspiration, and malignant tumors.

    2016-05-01

    Osteomyelitis of the hand is uncommon, but if not adequately and promptly treated the detrimental effects on hand function can be devastating. The majority of literature on osteomyelitis relates to the lower limb, but the principles of management are applicable to the hand, with good surgical debridement and culture-guided antimicrobial therapy. For osteomyelitis in general, antibiotic therapy of 4-6 weeks' duration (intravenous and/or oral) is typically recommended. In the hand, length and mode of antibiotic administration are still under study. V. © The Author(s) 2015.

    The authors define the phenomenon of spontaneous heating in underground coal mines as a combination of seam factor, geological factor and mining factor. These latter two factors are discussed in a practical manner from the early work of Fayol in 1879 through to the findings of modern day researchers. The paper assesses the significance of all relevant aspects affecting spontaneous heating of coal, and provides the basis for a better understanding of its complex causes. 7 figs., 24 refs.

    Anthony, Shawn; Lozano-Calderon, Santiago; Ring, David

    2008-03-01

    Failure to provide a balanced evidence-based consideration of the role of activity in illness can stigmatize individuals and their activities. We assessed the prevalence of language that stigmatized repetitive hand use and those that use their hand repetitively in newspaper coverage of common hand illnesses. The LexisNexis Academic database was used to search five major US newspapers for articles containing keywords about common hand illnesses during a 3-year period. Article language was assessed for stigmatization of activities involving repetitive hand use as well as for stigmatization of patients who use their hand repetitively. One hundred and twenty-four articles on hand illnesses were identified. Of these, 65.3% of articles stigmatized activities involving repetitive hand use, including 96.6% of articles discussing overuse injury of the hand, 90% of articles discussing tendonitis or tenosynovitis, and 51.8% of articles discussing carpal tunnel syndrome. Patient stigmatization was documented in 30.6% of the newspaper articles. Stigmatizing statements were most commonly made by journalists (94.8%), followed by patients (3.1%), and physicians (2.1%). Language that stigmatizes repetitive hand use and patients who use their hand repetitively is prevalent among US newspaper articles. Both health professionals and journalists reporting health-related news should be more sensitive to the use of stigmatizing language and provide a more balanced, measured, and evidenced-based account of hand illnesses.

  15. Hand washing for preventing diarrhoea.

    2008-01-23

    Diarrhoea is a common cause of morbidity and a leading cause of death among children aged less than five years, particularly in low- and middle-income countries. It is transmitted by ingesting contaminated food or drink, by direct person-to-person contact, or from contaminated hands. Hand washing is one of a range of hygiene promotion interventions that can interrupt the transmission of diarrhoea-causing pathogens. To evaluate the effects of interventions to promote hand washing on diarrhoeal episodes in children and adults. In May 2007, we searched the Cochrane Infectious Diseases Group Specialized Register, CENTRAL (The Cochrane Library 2007, Issue 2), MEDLINE, EMBASE, LILACS, PsycINFO, Science Citation Index and Social Science Citation Index, ERIC (1966 to May 2007), SPECTR, Bibliomap, RoRe, The Grey Literature, and reference lists of articles. We also contacted researchers and organizations in the field. Randomized controlled trials, where the unit of randomization is an institution (eg day-care centre), household, or community, that compared interventions to promote hand washing or a hygiene promotion that included hand washing with no intervention to promote hand washing. Two authors independently assessed trial eligibility and methodological quality. Where appropriate, incidence rate ratios (IRR) were pooled using the generic inverse variance method and random-effects model with 95% confidence intervals (CI). Fourteen randomized controlled trials met the inclusion criteria. Eight trials were institution-based, five were community-based, and one was in a high-risk group (AIDS patients). Interventions promoting hand washing resulted in a 29% reduction in diarrhoea episodes in institutions in high-income countries (IRR 0.71, 95% CI 0.60 to 0.84; 7 trials) and a 31% reduction in such episodes in communities in low- or middle-income countries (IRR 0.69, 95% CI 0.55 to 0.87; 5 trials). Hand washing can reduce diarrhoea episodes by about 30%. This significant

  16. Ziprasidone-induced spontaneous orgasm.

    Science.gov (United States)

    Boora, K; Chiappone, K; Dubovsky, S; Xu, J

    2010-06-01

    Neuroleptic treatment in schizophrenic patients has been associated with sexual dysfunction, including impotence and decreased libido. Spontaneous ejaculation without sexual arousal during typical antipsychotic treatment is a rare condition that has been described with zuclopentixol, trifluoperazine, and thiothixene. Here, we are reporting a case of spontaneous orgasm with ziprasidone in a bipolar patient. This patient began to repeatedly experience spontaneous sexual arousal and orgasm, which she had never experienced in the past. Ziprasidone might be causing an increase in sexual orgasm by 5-HT2 receptor antagonism, which preclinical evidence suggests that it facilitates dopamine release in the cortex.

  17. [Hand surgery training].

    2003-10-01

    Training of the hand surgeon HAND SURGEON A CONCEPT: The hand surgeon is supposed to be in charge of all the hand lesions regarding, skeleton, muscles, tendons, nerves and vessels. He has to be able to insure reparation and coverage of all of them. So he is involved in all the structures, which insure integrity and function of the hand. PURPOSE AND WAYS OF TRAINING: To obtain the asked ability, the hand surgeon training has to be global and sustained by two underlying surgical specialities: orthopedic surgery and plastic and reconstructive surgery. From 2000 after many years of dealings, a Right to the Title in Hand Surgery was born. This Right to the Title wants to be the formal recognition of the specific training of the hand surgeon. For the well-recognized ancient hand surgeons they need to be confirmed by one's peers. Now a day the hand surgeon has to satisfy to this specific training: Passed the complete training and exam of the Orthopedic or Plastic surgery board. Spent at least 6 months as resident in the other underlying specialty. Passed a microsurgery examination. Passed one of the four national Hand Surgery diplomas (DIU/Inter-Universitary Diploma). The examinations have been harmonized. A common formation is delivered regarding hand surgery, the way of examination is the same and the formation is 2 years long. The final exam is presented in front of board of examiners where a teacher of one of the other three national diplomas is present. Spent at least 2 years in a formative hand surgery unit, listed by the French College of Hand Surgeons, as senior surgeon. Those requirements are heavy to assume and need a heavy personal involvement. That seems to be necessary to have an ability level as high as possible. Emergency surgery practice is absolutely necessary in this training. All the 17 university formative hand surgery units listed by the French College of Hand Surgeons are members of the FESUM (European Federation of the Emergency Hand Units

    Full Text Available Spontaneous Potential Investigations in Semenic Mountains. The use of geophysical methods such as that of Spontaneous Potential (SP to investigate areas where the geomorphological processes occur, has the role to identify less visible processes as for example subcutaneous erosion or piping, subsoil water drainage and finding specific spatial differences of these processes. Comparative study of these sites allows correlation between geomorphological factors, soil and climate, but also to observe the evolution of subsurface erosion or underground water infiltration over time. During this investigation a series of mesh grids have been made in areas with different characteristics (lithology, pedology, slope, exposition, etc. at different time periods in order to spot and analyse the change in data in the chosen sites, various conditions given. Values expressed in millivolts (mV obtained by the Spontaneous Potential method have been put into an algorithm for interpolation looking to yield a pattern of values of what is happening in the soil during that period of time. Thus, in the autumn, the investigation site at the nivation niche Baia Vulturilor, returned values of between -22.6 mV and 65.6 mV, while in spring in the same site, values were within the range of -14.4 mV / 30.1 mV. On the other hand, on the site of the cryopediment under the Semenic peak, in the spring, return values ranged from -40.4 mV and -1.1 mV. A particular case is that of the glacis near Piatra Goznei peak; in this area anthropogenic electricity influences on soil can be found. Based on some models a trend of water movement in the soil could be established, this depending heavily on the amount of precipitation infiltration, local lithology, depth of soil and their structure, and evapotranspiration process. Water movement in the soil may be a correlation with sediment movement in soil horizons and instability manifested on the slopes.

    Full Text Available Vinodan Paramanathan, Ardalan ZolnourianQueen's Hospital NHS Foundation Trust, Burton on Trent, Staffordshire DE13 0RB, UKAbstract: Spontaneous intraorbital hematoma is an uncommon clinical entity seen in ophthalmology practice. It is poorly represented in the literature. Current evidence attributes it to orbital trauma, neoplasm, vascular malformations, acute sinusitis, and systemic abnormalities. A 65-year-old female presented with spontaneous intraorbital hematoma manifesting as severe ocular pains, eyelid edema, proptosis, and diplopia, without a history of trauma. Computer tomography demonstrated a fairly well defined extraconal lesion with opacification of the paranasal sinuses. The principal differential based on all findings was that of a spreading sinus infection and an extraconal tumor. An unprecedented finding of a spontaneous orbital hematoma was discovered when the patient was taken to theater. We discuss the rarity of this condition and its management.Keywords: hemorrhage, ophthalmology, spontaneous, intra-orbital, hematoma

    To characterize handwashing behaviors of children and assess the efficacy of a waiting room-based hand hygiene intervention at improving handwashing ability. Prospective randomized pilot study. Emergency department waiting room at a freestanding urban pediatric hospital. Children (8-18 years) and their parent. Participants were randomized to glow gel hand washing without hand hygiene education or glow gel hand washing with hand hygiene education. After participants washed with glow gel, "dirty areas" were illuminated using a black light, and hands were scored. A questionnaire about handwashing behavior was administered. All subjects returned 2-4 weeks after intervention to repeat glow gel hand washing and the questionnaire. Sixty pediatric patients and 57 parents were recruited, with 77% of patients returning for follow up. Patients were 50% male, 58% Latino, 28% African American, and 8% Caucasian. At the initial visit, 91% of children reported hand washing after using the bathroom and 78% reported hand washing before dinner. On the basis of objective scoring, all children improved handwashing ability when compared with the initial visit (P = .02) and were more likely to use warm water at follow up (P = .01). Parents did not significantly improve in handwashing ability (P = .73). Glow gel hand washing is an effective method to improve children's handwashing ability. This short-term intervention was effective even in the absence of specific hand hygiene education. This intervention could serve as a valuable public health measure to teach hand washing in healthcare settings.

    BACKGROUND Hand hygiene is the core element of infection prevention and control. The optimal hand-hygiene gesture, however, remains poorly defined. OBJECTIVE We aimed to evaluate the influence of hand-rubbing duration on the reduction of bacterial counts on the hands of healthcare personnel (HCP). METHODS We performed an experimental study based on the European Norm 1500. Hand rubbing was performed for 10, 15, 20, 30, 45, or 60 seconds, according to the WHO technique using 3 mL alcohol-based hand rub. Hand contamination with E. coli ATCC 10536 was followed by hand rubbing and sampling. A generalized linear mixed model with a random effect on the subject adjusted for hand size and gender was used to analyze the reduction in bacterial counts after each hand-rubbing action. In addition, hand-rubbing durations of 15 and 30 seconds were compared to assert non-inferiority (0.6 log10). RESULTS In total, 32 HCP performed 123 trials. All durations of hand rubbing led to significant reductions in bacterial counts (Phand rubbing were not significantly different from those obtained after 30 seconds. The mean bacterial reduction after 15 seconds of hand rubbing was 0.11 log10 lower (95% CI, -0.46 to 0.24) than after 30 seconds, demonstrating non-inferiority. CONCLUSIONS Hand rubbing for 15 seconds was not inferior to 30 seconds in reducing bacterial counts on hands under the described experimental conditions. There was no gain in reducing bacterial counts from hand rubbing longer than 30 seconds. Further studies are needed to assess the clinical significance of our findings.

  15. Smart Hand For Manipulators

    Science.gov (United States)

    Fiorini, Paolo

    1987-10-01

    Sensor based, computer controlled end effectors for mechanical arms are receiving more and more attention in the robotics industry, because commonly available grippers are only adequate for simple pick and place tasks. This paper describes the current status of the research at JPL on a smart hand for a Puma 560 robot arm. The hand is a self contained, autonomous system, capable of executing high level commands from a supervisory computer. The mechanism consists of parallel fingers, powered by a DC motor, and controlled by a microprocessor embedded in the hand housing. Special sensors are integrated in the hand for measuring the grasp force of the fingers, and for measuring forces and torques applied between the arm and the surrounding environment. Fingers can be exercised under position, velocity and force control modes. The single-chip microcomputer in the hand executes the tasks of communication, data acquisition and sensor based motor control, with a sample cycle of 2 ms and a transmission rate of 9600 baud. The smart hand described in this paper represents a new development in the area of end effector design because of its multi-functionality and autonomy. It will also be a versatile test bed for experimenting with advanced control schemes for dexterous manipulation.

    Atoms and molecules are too small to act as efficient antennas for their own emission wavelengths. By providing an external optical antenna, the balance can be shifted; spontaneous emission could become faster than stimulated emission, which is handicapped by practically achievable pump intensities. In our experiments, InGaAsP nanorods emitting at ∼ 200 THz optical frequency show a spontaneous emission intensity enhancement of 35 × corresponding to a spontaneous emission rate speedup ∼ 115 ×, for antenna gap spacing, d = 40 nm. Classical antenna theory predicts ∼ 2,500 × spontaneous emission speedup at d ∼ 10 nm, proportional to 1/d(2). Unfortunately, at d < 10 nm, antenna efficiency drops below 50%, owing to optical spreading resistance, exacerbated by the anomalous skin effect (electron surface collisions). Quantum dipole oscillations in the emitter excited state produce an optical ac equivalent circuit current, I(o) = qω|x(o)|/d, feeding the antenna-enhanced spontaneous emission, where q|x(o)| is the dipole matrix element. Despite the quantum-mechanical origin of the drive current, antenna theory makes no reference to the Purcell effect nor to local density of states models. Moreover, plasmonic effects are minor at 200 THz, producing only a small shift of antenna resonance frequency.

    2014-01-01

    Background Hand hygiene compliance has improved significantly through hand hygiene promotion programs that have included poster campaign, monitoring and performance feedback, and education with special attentions to perceived subjective norms. We investigated factors associated with improved hand hygiene compliance, focusing on whether the improvement of hand hygiene compliance is associated with changed perception toward hand hygiene among medical personnel. Materials and Methods Hand hygiene compliance and perceptions toward hand hygiene among medical personnel were compared between the second quarter of 2009 (before the start of a hand hygiene promotion program) and the second quarter of 2012. We assessed adherence to hand hygiene among medical personnel quarterly according to the WHO recommended method for direct observation. Also, we used a modified self-report questionnaire to collect perception data. Results Hand hygiene compliance among physicians and nurses improved significantly from 19.0% in 2009 to 74.5% in 2012 (P Hand hygiene compliance among the medical personnel continued to improve, with a slight decline in 2013. Perceptions toward hand hygiene improved significantly between 2009 and 2012. Specifically, improvements were evident in intention to adhere to hand hygiene, knowledge about hand hygiene methods, knowledge about hand hygiene indications including care of a dirty and a clean body site on the same patient, perceived behavioral and subjective norms, positive attitude toward hand hygiene promotion campaign, perception of difficulty in adhering to hand hygiene, and motivation to improve adherence to hand hygiene. Conclusions The examined hand hygiene promotion program resulted in improved hand hygiene compliance and perception toward hand hygiene among medical personnel. The improved perception increased hand hygiene compliance. Especially, the perception of being a role model for other colleagues is very important to improve hand hygiene

  1. A geometric morphometric assessment of hand shape and comparison to the 2D:4D digit ratio as a marker of sexual dimorphism.

    2013-04-01

    Twin studies are extremely useful for investigating hypotheses of genetic influence on a range of behavioral and physical traits in humans. Studies of physical traits, however, are usually limited to size-related biological characteristics because it is inherently difficult to quantify the morphological counterpart - shape. In recent years, the development of geometry-preserving analytical techniques built upon multivariate statistical methodologies has produced a new discipline in biological shape analysis known as geometric morphometrics. In this study of hand shape analysis, we introduce the reader already familiar with the field of twin research to the potential utility of geometric morphometrics and demonstrate the cross-discipline applicability of methods. We also investigate and compare the efficacy of the 2D:4D ratio, a commonly used marker of sexual dimorphism, to the fully multivariate approach of shape analysis in discriminating between male and female sex. Studies of biological shape variation utilizing geometric morphometric techniques may be completed with software freely available on the Internet and time invested to master the small learning curve in concepts and theory.

    Questions surrounding the origin and early evolution of primates continue to be the subject of debate. Though anatomy of the skull and inferred dietary shifts are often the focus, detailed studies of postcrania and inferred locomotor capabilities can also provide crucial data that advance understanding of transitions in early primate evolution. In particular, the hand skeleton includes characteristics thought to reflect foraging, locomotion, and posture. Here we review what is known about the early evolution of primate hands from a comparative perspective that incorporates data from the fossil record. Additionally, we provide new comparative data and documentation of skeletal morphology for Paleogene plesiadapiforms, notharctines, cercamoniines, adapines, and omomyiforms. Finally, we discuss implications of these data for understanding locomotor transitions during the origin and early evolutionary history of primates. Known plesiadapiform species cannot be differentiated from extant primates based on either intrinsic hand proportions or hand-to-body size proportions. Nonetheless, the presence of claws and a different metacarpophalangeal [corrected] joint form in plesiadapiforms indicate different grasping mechanics. Notharctines and cercamoniines have intrinsic hand proportions with extremely elongated proximal phalanges and digit rays relative to metacarpals, resembling tarsiers and galagos. But their hand-to-body size proportions are typical of many extant primates (unlike those of tarsiers, and possibly Teilhardina, which have extremely large hands). Non-adapine adapiforms and omomyids exhibit additional carpal features suggesting more limited dorsiflexion, greater ulnar deviation, and a more habitually divergent pollex than observed plesiadapiforms. Together, features differentiating adapiforms and omomyiforms from plesiadapiforms indicate increased reliance on vertical prehensile-clinging and grasp-leaping, possibly in combination with predatory behaviors in

  4. Are there excitability changes in the hand motor cortex during speech in left-handed subjects?

    2012-01-01

    Hemispheric dominance was investigated in left-handed subjects using single transcranial magnetic stimulation to assess the possible effect of forced change in the dominant hand. Single transcranial magnetic stimuli were delivered randomly over the hand area of the left or right motor cortex of 8 Japanese self-declared left-handed adult volunteers. Electromyographic responses were recorded in the relaxed first dorsal interosseous muscle while the subjects read aloud. Laterality quotient calculated by the Edinburgh Inventory ranged from -100 to -5.26 and laterality index calculated from motor evoked potentials ranged from -86.2 to 38.8. There was no significant correlation between laterality quotient and laterality index. Mean data values across all 8 subjects indicated significant increases only in the left hand. Our ratio analysis of facilitation of the hand motor potentials showed that 2 each of the 8 self-declared left-handers were right- and left-hand dominant and the other 4 were bilateral-hand dominant. Speech dominancy was localized primarily in the right cerebral hemisphere in left-handed subjects, but some individuals exhibited bilateral or left dominance, possibly attributable to the forced change of hand preference for writing in childhood. Our findings suggest changes in the connections between the speech and hand motor areas.

    Full Text Available Spontaneous intracranial hypotension is an important cause of new daily persistent headaches in young and middle-aged individuals. The diagnosis is made based on low cerebrospinal fluid pressure with characteristic findings upon brain and spinal magnetic resonance imaging (MRI. We present the case of a 15-year-old boy with spontaneous intracranial hypotension. Although his brain MRI was normal, his lumbar spinal MRI showed clustering of the nerve roots characteristic of arachnoiditis. Radionuclide cisternography revealed an epidural leak, which was treated with an epidural blood patch. The patient reached a near-full recovery within 24 h, and the lumbar spinal MRI findings mimicking arachnoiditis disappeared.

    Mechanical oscillations are important for many cellular processes, e.g. the beating of cilia and flagella or the sensation of sound by hair cells. These dynamic states originate from spontaneous oscillations of molecular motors. A particularly clear example of such oscillations has been observed in muscle fibers under non-physiological conditions. In that case, motor oscillations lead to contraction waves along the fiber. By a macroscopic analysis of muscle fiber dynamics we find that the spontaneous waves involve non-hydrodynamic modes. A simple microscopic model of sarcomere dynamics highlights mechanical aspects of the motor dynamics and fits with the experimental observations.

    Full Text Available Dyspepsia with mild, stabbing epigastric discomfort without history of trauma is a very common symptom that emergency physicians see in their daily practice. Vascular emergencies, mostly the aortic dissection and aneurysm, are always described in the differential diagnosis with persistent symptoms. Isolated celiac artery dissection occurring spontaneously is a very rare diagnosis. The involvement of branch vessels is generally observed and patients show various clinical signs and symptoms according to the involved branch vessel. Here we are presenting a case with spontaneous isolated celiac artery dissection, without any branch vessel involvement or visceral damage, detected by computed tomography scans taken on admission.

    The lack of scientific evidence on the constituents, properties, and health effects of second-hand waterpipe smoke has fueled controversy over whether public smoking bans should include the waterpipe. The purpose of this study was to investigate and compare emissions of ultrafine particles (UFP, tobacco smoke. Sidestream cigarette and waterpipe smoke was captured and aged in a 1 m 3 Teflon-coated chamber operating at 1.5 air changes per hour (ACH). The chamber was characterized for particle mass and number surface deposition rates. UFP and CO concentrations were measured online using a fast particle spectrometer (TSI 3090 Engine Exhaust Particle Sizer), and an indoor air quality monitor. Particulate PAH and gaseous volatile aldehydes were captured on glass fiber filters and DNPH-coated SPE cartridges, respectively, and analyzed off-line using GC-MS and HPLC-MS. PAH compounds quantified were the 5- and 6-ring compounds of the EPA priority list. Measured aldehydes consisted of formaldehyde, acetaldehyde, acrolein, methacrolein, and propionaldehyde. We found that a single waterpipe use session emits in the sidestream smoke approximately four times the carcinogenic PAH, four times the volatile aldehydes, and 30 times the CO of a single cigarette. Accounting for exhaled mainstream smoke, and given a habitual smoker smoking rate of 2 cigarettes per hour, during a typical one-hour waterpipe use session a waterpipe smoker likely generates ambient carcinogens and toxicants equivalent to 2-10 cigarette smokers, depending on the compound in question. There is therefore good reason to include waterpipe tobacco smoking in public smoking bans.

    Because hand eczema and fragrance allergy are common both among patients and in the general population, simultaneous occurrence by chance must be expected. Fragrances are ubiquitous and a part of many domestic and occupational products intended for hand exposure. The present review is based...... on a systematic literature research using both a manual and a Medline based search. The search identified 39 studies, including epidemiological patch test studies, general population patch test studies, case studies, and studies of occupational groups. The published data indicate a possible association between...... fragrance allergy and hand eczema. In future studies, a more detailed exposure assessment is needed, combined with patch test studies among patients with hand eczema tested with relevant fragrance allergens, as well as experimental control exposure studies to specific fragrance allergens on the hands...

  11. Pediatric hand burns: thermal, electrical, chemical.

    2009-07-01

    Young children often use their hands for exploration of their surroundings, and this often leads to the hand being the primary site of injury. Because of this and many associated factors, burns of the pediatric hands are relatively common, with thermal injuries being the most frequent. Electrical and chemical etiologies contribute a minor portion of the burn injuries in the pediatric population. Some key differences should be considered in the management of hand burns in a pediatric patient versus an adult. In general, minor superficial burns will heal satisfactorily only with topical care. Deeper partial-thickness and full-thickness burns, however, require surgical interventions. Special care should always be taken in the management of electrical and chemical burns because the pathophysiology of these injuries are unique. Treatment of pediatric hand burns should also involve close and thorough follow-up to assess not only for healing and restoration of function of the injury but also for psychologic and emotional trauma.

  12. Hand protection from ultraviolet exposure

    Full text of publication follows: A number of industrial applications and public services involve exposure to ultraviolet radiation (U.V.R.) from a variety of lamps and lasers, for example, in forensic examination, biological trans-illuminators, dentistry, laser material processing, microelectronics, etc. The proposed European Union Directive on Optical Radiation would place specific requirements on employers to provide adequate safety measures to reduce exposure to U.V.R., including gloves for hand protection. The selection of gloves should be based on a risk assessment and on the performance characteristics of the gloves for the task. However, current International and national standards do not describe evaluation procedures of disposable gloves for hand protection against non-ionising radiation. A methodology for assessment of the UV protection level for disposable gloves and a simple measurement protocol are proposed, based on a common approach with UV protection by clothing and sunscreens. Glove Ultraviolet Protection Factor is defined as a time-scale increase in exposure permitted for the hand protected by a glove with respect to an unprotected hand. However, the wide variety of U.V.R. sources and the real-life conditions of glove use (stretching and wetting the surface by liquids) bring substantial challenges to the assessment method. Our study of {approx} 50 samples of widely used disposable gloves made of different materials (nitrile, vinyl, latex and chloroprene) showed that for all tested gloves a change in U.V.R. attenuation with stretching is characteristic for the type of glove material and can be included as a scaling factor in the definition of U.V.R. protection. Glove material has a bigger effect on U.V.R. protection level than variations in the glove thickness or its colour. The following approaches are suggested to overcome the problem of variable U.V.R. sources: - Worst case scenario minimal protection level, most restrictive case - Application

    Full Text Available Diabetes mellitus is a chronic metabolic condition characterized by persistent hyperglycaemia with resultant morbidity and mortality related to its microvascular and macrovascular complications. In addition diabetes is also associated with several musculoskeletal disorders of the hand, that can be debilitating. There is increased incidence of these abnormalities in patients with type 1 and type 2 diabetes compared with the general population, related to disease duration but not to the age or sex. Typical diabetes associated hand condition include the palmar flexor tenosynovitis, Dupuytren’s contracture, syndrome of limited joint mobility, carpal tunnel syndrome, Charcot arthropathy and reflex sympathetic dystrophy. Maintaining good glycaemic control by exercise, diet and drugs improves or prevents the development of these hand rheumatic condition. In this brief report we review the rational therapeutic approach to these disorders.

    Hand hygiene has now been recognised as one of the most effective intervention to control the transmission of infections in a hospital and education is an important tool to ensure its implementation. In order to convince the users and as a part of education, it is important to generate evidence on the role of hand hygiene in reducing the bacterial flora on their hands. The present study was undertaken in a tertiary care hospital to demonstrate the presence of bacterial flora on the hands of healthcare workers (HCW) in different categories, to teach them proper hand hygiene technique using alcohol-based hand rub and determine the outcome for reduction of bacteria. A total sample size of 60 subjects including resident doctors, medical students, nurses and hospital attendants were included in the study after obtaining informed consent. Each person was educated on the technique of hand hygiene with alcohol-based hand rub and hand impressions were cultured before and after hand hygiene. All the subjects were also given a questionnaire to assess their perception on hand hygiene. The WHO posters on proper hand hygiene were displayed in the appropriate areas of the hospital in addition, as an educational tool. Majority (42 out of 60) of the HCWs had bacterial count up to 100 colonies or more on both hands before the application of hand rub while working in the hospital. After use of alcohol hand rub with a proper hand hygiene technique, it was found that the percentage reduction was 95-99% among doctors and nurses, 70% among hospital attendants and 50% among sanitary attendants. Staphylococcus aureus was present on the hands of eight persons of which three were methicillin-resistant Staphylococcus aureus. The study demonstrates that transient bacteria are present on the hands of HCWs but majority could be removed by proper hand hygiene, which needs continuous education to be effective. It also shows that active education by demonstrating the proper hand hygiene technique

  17. Being Spontaneous: The Future of Telehealth Implementation?

    Mars, Maurice; Scott, Richard E

    2017-09-01

    The smartphone simplifies interprofessional communication, and smartphone applications can facilitate telemedicine activity. Much has been written about the steps that need to be followed to implement and establish a successful telemedicine service that is integrated into everyday clinical practice. A traditional and systematic approach has evolved incorporating activities such as strategy development, needs assessment, business cases and plans, readiness assessment, implementation plans, change management interventions, and ongoing monitoring and evaluation. This "best practice" has been promoted in the telehealth literature for many years. In contrast, several recent initiatives have arisen without any such formal undertakings. This article describes the strengths and weaknesses of two "spontaneous" telemedicine services in dermatology and burn management that have evolved in South Africa. Two spontaneous services were identified and reviewed. In one unsolicited service, doctors at rural referring hospitals have been taking photographs of skin lesions and sending them with a brief text message history to dermatologists using the instant messaging smartphone app, WhatsApp. In the other, burns service, admissions to the burns unit or the clinic were triaged by telephonic description of the case and completion of a preadmission questionnaire. More recently, management and referral decisions are made only after completion of the questionnaire and subsequent submission of photographs of the burn sent by WhatsApp, with the decision transmitted by text message. Although efficient and effective, potential legal and ethical shortcomings have been identified. These "spontaneous" telehealth services challenge traditional best practice, yet appear to lead to truly integrated practice and, therefore, are successful and warrant further study.

    Hand dermatitis is a common diagnosis seen in dermatologic and general practice. It can present with typical morphology, but uncommon manifestations are possible. This review reports on common and uncommon presentations of irritant and allergic hand dermatitis focusing on uncommon localizations, time course, and morphology such as follicular, pustular, bullous, ulcerous, exudative erythema multiforme-like, purpuric, lichenoid, pigmented, and depigmented skin lesions. Clinical diagnosis can be challenging. Even histopathology is not always very helpful. Thorough evaluation of the patient's history and investigation of clinical morphology are the cornerstones of diagnosis.

    2015-02-01

    Hand grip strength in both the dominant and non-dominant hands is often used to assess upper limb impairment. Excessive hand grip fatigability is another important measure, as fatigability may also influence activities of daily living. To investigate to what extent hand grip fatigability in multiple sclerosis is dependent on hand dominance, muscle strength and disease progression. Thirty persons with multiple sclerosis and 16 healthy controls performed 15 repeated maximal hand grip contractions and a 30 s sustained contraction in order to determine dynamic and static fatigue indices. Fatigability was compared between the dominant and non-dominant hands and between the more and less affected hands in a subgroup of persons with multiple sclerosis with asymmetrical hand grip strength impairment. Furthermore, fatigability was compared between controls and subgroups of persons with multiple sclerosis with different disease progression. There was no difference in fatigability between dominant and non-dominant hands in healthy controls or in persons with multiple sclerosis. Similarly, there was no difference between the more and less affected hands in the subgroup of persons with multiple sclerosis with asymmetrical hand grip impairment. The dynamic fatigue index did not discriminate persons with multiple sclerosis from controls. While the static fatigue index was not different between healthy controls and persons with multiple sclerosis with low to moderate (hand grip strength in persons with multiple sclerosis is not influenced by hand dominance or muscle strength, but there is a correlation with disease progression. Differences in fatigability between healthy controls and, in particular, persons with multiple sclerosis with high EDSS, were found during sustained, but not during dynamic, contractions.

    To assess the maturation disparity of hand-wrist bones using the BoneXpert system and Greulich and Pyle (GP) atlas in a sample of normal children from China. Our study included 229 boys and 168 girls aged 2 - 14 years. The bones in the hand and wrist were divided into five groups: distal radius and ulna, metacarpals, proximal phalanges, middle phalanges and distal phalanges. Bone age (BA) was assessed separately using the automatic BoneXpert and GP atlas by two raters. Differences in the BA between the most advanced and retarded individual bones and bone groups were analyzed. In 75.8% of children assessed with the BoneXpert and 59.4% of children assessed with the GP atlas, the BA difference between the most advanced and most retarded individual bones exceeded 2.0 years. The BA mean differences between the most advanced and most retarded individual bones were 2.58 and 2.25 years for the BoneXpert and GP atlas methods, respectively. Furthermore, for both methods, the middle phalanges were the most advanced group. The most retarded group was metacarpals for BoneXpert, while metacarpals and the distal radius and ulna were the most retarded groups according to the GP atlas. Overall, the BAs of the proximal and distal phalanges were closer to the chronological ages than those of the other bone groups. Obvious and regular maturation disparities are common in normal children. Overall, the BAs of the proximal and distal phalanges are more useful for BA estimation than those of the other bone groups.

  6. Hand dominance in orthopaedic surgeons.

    2012-08-01

    Handedness is perhaps the most studied human asymmetry. Laterality is the preference shown for one side and it has been studied in many aspects of medicine. Studies have shown that some orthopaedic procedures had poorer outcomes and identified laterality as a contributing factor. We developed a questionnaire to assess laterality in orthopaedic surgery and compared this to an established scoring system. Sixty-two orthopaedic surgeons surveyed with the validated Waterloo Handedness Questionnaire (WHQ) were compared with the self developed Orthopaedic Handedness Questionnaire (OHQ). Fifty-eight were found to be right hand dominant (RHD) and 4 left hand dominant (LHD). In RHD surgeons, the average WHQ score was 44.9% and OHQ 15%. For LHD surgeons the WHQ score was 30.2% and OHQ 9.4%. This represents a significant amount of time using the non dominant hand but does not necessarily determine satisfactory or successful dexterity transferable to the operating room. Training may be required for the non dominant side.

    Hand is frequently the site of work accidents or occupational diseases. The musculoskeletal upper limb is the first recognized occupational disease and carpal tunnel syndrome is the most common of them. The most common location of occupational dermatoses is the hand. Their causes are often multifactorial, involving chemical irritants, physical, allergens and endogenous factors (mainly atopic dermatitis). Occupational exposure to microtrauma and iterative use of vibrating tools may also be the cause of hypothenar hammer syndrome and acrosyndromes. The frequent chronicity and functional impairment induced by these attacks can cause lasting disabilities, an inability to source workstation. Occupational physician is a focal point for helping to maintain the position and the prevention of socioprofessional disinsertion. Many pathologies of the hand related to professional activity may benefit from a statement in occupational disease and thus allow the patient to obtain compensation and employment protection. Prevention of occupational hand diseases should be made by all health actors, especially in occupations and industries at risk. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Qualitative assessment of spontaneous motor activity in early infancy is widely used in clinical practice. It enables the description of maturational changes of motor behavior in both healthy infants and infants who are at risk for later neurological impairment. These assessments are, however, time-consuming and are dependent upon professional experience. Therefore, a simple physiological method that describes the complex behavior of spontaneous movements (SMs) in infants would be helpful. In this methodological study, we aimed to determine whether time series of motor acceleration measurements at 40-44 weeks and 50-55 weeks gestational age in healthy infants exhibit fractal-like properties and if this self-affinity of the acceleration signal is sensitive to maturation. Healthy motor state was ensured by General Movement assessment. We assessed statistical persistence in the acceleration time series by calculating the scaling exponent α via detrended fluctuation analysis of the time series. In hand trajectories of SMs in infants we found a mean α value of 1.198 (95 % CI 1.167-1.230) at 40-44 weeks. Alpha changed significantly (p = 0.001) at 50-55 weeks to a mean of 1.102 (1.055-1.149). Complementary multilevel regression analysis confirmed a decreasing trend of α with increasing age. Statistical persistence of fluctuation in hand trajectories of SMs is sensitive to neurological maturation and can be characterized by a simple parameter α in an automated and observer-independent fashion. Future studies including children at risk for neurological impairment should evaluate whether this method could be used as an early clinical screening tool for later neurological compromise.

    Endourology has evolved rapidly for the management of both benign and malignant disease of the upper urinary tract. Limited data exist, however, on the occupational hazards posed by complex endourologic procedures. The aim of this study was to determine the prevalence and possible causes of hand problems among endourologists who routinely perform flexible ureteroscopy compared with controls. An online computer survey targeted members of the Endourological Society and psychiatrists in academic and community settings. A total of 600 endourologists and 578 psychiatrists were contacted by e-mail. Invited physicians were queried regarding their practice settings and symptoms of hand pain, neuropathy, and/or discomfort. Survey responses were obtained from 122 (20.3%) endourologists and 74 (12.8%) psychiatrists. Of endourologists, 61% were in an academic setting and 70% devoted their practice to endourology. Endourologists were in practice for a mean 13 years, performing 4.5 ureteroscopic cases per week with a mean operative time of 50 minutes. Hand/wrist problems were reported by 39 (32%) endourologists compared with 14 (19%) psychiatrists (P=0.0486, relative risk [RR]=1.69). Surgeons who preferred counterintuitive ureteroscope deflection were significantly more likely to have problems (56%) compared with intuitive users (27%) (RR 2.07, P=0.0139) or those with no preference (26%) (RR 2.15, P=0.0451). Overall, most respondents (85%) with hand/wrist problems needed either medical or surgical intervention. Hand and wrist problems are very common among endourologists. Future studies are needed to develop more ergonomic platforms and thereby reduce the endourologist's exposure to these occupational hazards.

    neuronal networks with neuron clustering. To test this, we created networks of varying architecture in vitro Supporting these predictions, the generation and spatiotemporal patterns of propagation were most variable in networks with intermediate clustering and lowest in uniform networks. Grid-like clustering, on the other hand, facilitated spontaneous activity but led to degenerating patterns of propagation. Neurons outside clusters had weaker synaptic input than neurons within clusters, in which increased membrane potential fluctuations facilitated the initiation of synchronized spike activity. Our results thus show that the intermediate level organization of neuronal networks strongly influences the dynamics of their activity. Copyright © 2017 the authors 0270-6474/17/373972-16$15.00/0.

    2016-12-01

    In this work, we develop a model for Higgs-like composites based on two generations of right-handed neutrinos that condense. We analyze the spontaneous symmetry breaking of the theory with two explicit breakings, setting the different scales of the model and obtaining massive bosons as a result. Finally, we calculate the gravitational wave imprint left by the phase transition associated with the symmetry breaking of a generic potential dictated by the symmetries of the composites.

    It has been shown that combinations of visual, tactile, and proprioceptive manipulations in healthy subjects may elicit illusory feelings of embodiment (the rubber hand illusion and the somatic rubber hand illusion). We report a case of alien hand syndrome in which the alien hand interacted with the somatic rubber hand illusion to provoke a very strong movement of the alien hand. This effect could be reliably replicated at every application of the experimental procedure. Thus, the illusion seemed to wake up the alien hand. The results demonstrate that the alien hand syndrome can be affected by experimentally induced bodily illusions, which are based on the manipulation of touch and proprioceptive information.

    Full Text Available Brain lesions may disturb hand functioning in children with cerebral palsy (CP, making it difficult or even impossible for them to perform several manual activities. Most conventional treatments for hand dysfunction in CP assume that reducing the hand dysfunctions will improve the capacity to manage activities (i.e., manual ability, MA. The aim of this study was to investigate the directional relationships (direct and indirect pathways through which hand skills influence MA in children with CP. A total of 136 children with CP (mean age: 10 years; range: 6–16 years; 35 quadriplegics, 24 diplegics, 77 hemiplegics were assessed. Six hand skills were measured on both hands: touch-pressure detection (Semmes-Weinstein aesthesiometer, stereognosis (Manual Form Perception Test, proprioception (passive mobilization of the metacarpophalangeal joints, grip strength (Jamar dynamometer, gross manual dexterity (Box and Block Test, and fine finger dexterity (Purdue Pegboard Test. MA was measured with the ABILHAND-Kids questionnaire. Correlation coefficients were used to determine the linear associations between observed variables. A path analysis of structural equation modeling was applied to test different models of causal relationships among the observed variables. Purely sensory impairments did seem not to play a significant role in the capacity to perform manual activities. According to path analysis, gross manual dexterity in both hands and stereognosis in the dominant hand were directly related to MA, whereas grip strength was indirectly related to MA through its relationship with gross manual dexterity. However, one-third of the variance in MA measures could not be explained by hand skills. It can be concluded that MA is not simply the integration of hand skills in daily activities and should be treated per se, supporting activity-based interventions.

    To assess the impact of a hand hygiene protocol, using hand washing, alcohol hand rub and gloves when caring for preterm infants born after 31 weeks of gestation, on the incidence of neonatal late onset sepsis (LOS). All babies delivered between 32 + 0 and 36 + 6 weeks gestation and admitted to the neonatal intensive care unit during a 14-month period were included. We followed a hand hygiene protocol with hand washing and alcohol hand rub (hand rub period) for the first 7 months and a protocol of hand washing, alcohol hand rub and gloves (gloves period) for the second 7 months. The hand rub and gloves groups consisted of 111 and 89 patients, respectively. Five patients were diagnosed with a total of six episodes of LOS in the hand rub group, and the incidence of LOS during the hand rub period was 2.99/1000 hospital days and 54.1/1000 admissions. There were no patients diagnosed with LOS during the gloves period (significant decrease, p = 0.028). Using a hand hygiene protocol with hand washing, hand rub and gloves significantly reduced the incidence of LOS in preterm newborns, and the results suggest that it may produce a sustained improvement in the infection rate. ©2014 Foundation Acta Paediatrica.

    Spontaneous abortion is rarely addressed in moral evaluations of abortion. Indeed, 'abortion' is virtually always taken to mean only induced abortion. After a brief review of medical aspects of spontaneous abortion, I attempt to articulate the moral implications of spontaneous abortion for the two poles of the abortion debate, the strong pro-abortion and the strong anti-abortion positions. I claim that spontaneous abortion has no moral relevance for strict pro-abortion positions but that the ...

    2016-08-01

    Alien hand syndrome (AHS) is a rare disorder of involuntary limb movement together with a sense of loss of limb ownership. It most commonly affects the hand, but can occur in the leg. The anterior (frontal, callosal) and posterior variants are recognized, with distinguishing clinical features and anatomical lesions. Initial descriptions were attributed to stroke and neurosurgical operations, but neurodegenerative causes are now recognized as most common. Structural and functional imaging and clinical studies have implicated the supplementary motor area, pre-supplementary motor area, and their network connections in the frontal variant of AHS, and the inferior parietal lobule and connections in the posterior variant. Several theories are proposed to explain the pathophysiology. Herein, we review the literature to update advances in the understanding of the classification, pathophysiology, etiology, and treatment of AHS.

    Polydactyly is considered either the most or second most (after syndactyly) common congenital hand abnormality. Polydactyly is not simply a duplication; the anatomy is abnormal with hypoplastic structures, abnormally contoured joints, and anomalous tendon and ligament insertions. There are many ways to classify polydactyly, and surgical options range from simple excision to complicated bone, ligament, and tendon realignments. The prevalence of polydactyly makes it important for orthopedic surgeons to understand the basic tenets of the abnormality.

    Lovchik, Christopher Scott (Inventor); Diftler, Myron A. (Inventor)

    2001-01-01

    A compact robotic hand includes a palm housing, a wrist section, and a forearm section. The palm housing supports a plurality of fingers and one or more movable palm members that cooperate with the fingers to grasp and/or release an object. Each flexible finger comprises a plurality of hingedly connected segments, including a proximal segment pivotally connected to the palm housing. The proximal finger segment includes at least one groove defining first and second cam surfaces for engagement with a cable. A plurality of lead screw assemblies each carried by the palm housing are supplied with power from a flexible shaft rotated by an actuator and output linear motion to a cable move a finger. The cable is secured within a respective groove and enables each finger to move between an opened and closed position. A decoupling assembly pivotally connected to a proximal finger segment enables a cable connected thereto to control movement of an intermediate and distal finger segment independent of movement of the proximal finger segment. The dexterous robotic hand closely resembles the function of a human hand yet is light weight and capable of grasping both heavy and light objects with a high degree of precision.

  10. Hand chemical burns.

    Robinson, Elliot P; Chhabra, A Bobby

    2015-03-01

    There is a vast and ever-expanding variety of potentially harmful chemicals in the military, industrial, and domestic landscape. Chemical burns make up a small proportion of all skin burns, yet they can cause substantial morbidity and mortality. Additionally, the hand and upper extremity are the most frequently involved parts of the body in chemical burns, and therefore these injuries may lead to severe temporary or permanent loss of function. Despite this fact, discussion of the care of these injuries is sparse in the hand surgery literature. Although most chemical burns require only first response and wound care, some require the attention of a specialist for surgical debridement and, occasionally, skin coverage and reconstruction. Exposure to certain chemicals carries the risk of substantial systemic toxicity and even mortality. Understanding the difference between thermal and chemical burns, as well as special considerations for specific compounds, will improve patient treatment outcomes.

  11. Spontaneous Photon Emission in Cavities

    Directory of Open Access Journals (Sweden)

    Alber G.

    2014-01-01

    Full Text Available We investigate spontaneous photon emission processes of two-level atoms in parabolic and ellipsoidal cavities thereby taking into account the full multimode scenario. In particular, we calculate the excitation probabilities of the atoms and the energy density of the resulting few-photon electromagnetic radiation field by using semiclassical methods for the description of the multimode scenario. Based on this approach photon path representations are developed for relevant transition probability amplitudes which are valid in the optical frequency regime where the dipole and the rotating-wave approximations apply. Comparisons with numerical results demonstrate the quality of these semiclassical results even in cases in which the wave length of a spontaneously emitted photon becomes comparable or even larger than characteristic length scales of the cavity. This is the dynamical regime in which diffraction effects become important so that geometric optical considerations are typically not applicable.

  12. Spontaneous rupture of the ureter

    Eken, Alper; Akbas, Tugana; Arpaci, Taner

    2015-01-01

    Spontaneous rupture of the ureter is a very rare condition and usually results from ureteral obstruction by a calculus. Only theoretical mecha­nisms have been proposed and no possible explanation has yet been reported in the literature. Intravenous contrast-enhanced computed tomography is the most informative study with high sensitivity. Treatment should be individualised, and depends on the state of the patient. Minimally invasive endourological procedures with double-J catheter placement and percutaneous drainage offer excellent results. Conservative management with analgesics and antibiotic coverage may be an alternative to surgery. Herein, we present a case of spontaneous rupture of the proximal ureter with no evidence of an underlying pathological condition. PMID:25715862

    A case of spontaneous regression of transverse colon cancer is reported. A 64-year-old man was diagnosed as having cancer of the transverse colon at a local hospital. Initial and second colonoscopy examinations revealed a typical cancer of the transverse colon, which was diagnosed as moderately differentiated adenocarcinoma. The patient underwent right hemicolectomy 6 weeks after the initial colonoscopy. The resected specimen showed only a scar at the tumor site, and no cancerous tissue was proven histologically. The patient is alive with no evidence of recurrence 1 year after surgery. Although an antitumor immune response is the most likely explanation, the exact nature of the phenomenon was unclear. We describe this rare case and review the literature pertaining to spontaneous regression of colorectal cancer. © The Author 2014. Published by Oxford University Press. All rights reserved.

  14. Spontaneous Rotational Inversion in Phycomyces

    KAUST Repository

    Goriely, Alain

    2011-03-01

    The filamentary fungus Phycomyces blakesleeanus undergoes a series of remarkable transitions during aerial growth. During what is known as the stagea IV growth phase, the fungus extends while rotating in a counterclockwise manner when viewed from above (stagea IVa) and then, while continuing to grow, spontaneously reverses to a clockwise rotation (stagea IVb). This phase lasts for 24-48Ah and is sometimes followed by yet another reversal (stageAIVc) before the overall growth ends. Here, we propose a continuum mechanical model of this entire process using nonlinear, anisotropic, elasticity and show how helical anisotropy associated with the cell wall structure can induce spontaneous rotation and, under appropriate circumstances, the observed reversal of rotational handedness. © 2011 American Physical Society.

    To assess reader performance and subjective workflow experience when reporting bone age studies with a digital bone age reference as compared to the Greulich and Pyle atlas (G and P). We hypothesized that pediatric radiologists would achieve equivalent results with each method while digital workflow would improve speed, experience, and reporting quality. IRB approval was obtained for this HIPAA-compliant study. Two pediatric radiologists performed research interpretations of bone age studies randomized to either the digital (Digital Bone Age Companion, Oxford University Press) or G and P method, generating reports to mimic clinical workflow. Bone age standard selection, interpretation-reporting time, and user preferences were recorded. Reports were reviewed for typographical or speech recognition errors. Comparisons of agreement were conducted by way of Fisher's exact tests. Interpretation-reporting times were analyzed on the natural logarithmic scale via a linear mixed model and transformed to the geometric mean. Subjective workflow experience was compared with an exact binomial test. Report errors were compared via a paired random permutation test. There was no difference in bone age determination between atlases (p = 0.495). The interpretation-reporting time (p < 0.001) was significantly faster with the digital method. The faculty indicated preference for the digital atlas (p < 0.001). Signed reports had fewer errors with the digital atlas (p < 0.001). Bone age study interpretations performed with the digital method were similar to those performed with the Greulich and Pyle atlas. The digital atlas saved time, improved workflow experience, and reduced reporting errors relative to the Greulich and Pyle atlas when integrated into electronic workflow. (orig.)

    2014-01-01

    Full Text Available Purpose: to assess early and long-term results of the pediatric hand reconstructions with posterior interosseous flap, including those in children younger than 3 years old. Materials and methods: results of the hand reconstructions with posterior interosseous artery reverse flap were studied in 10 children (4 males and 6 females aged from 1 year and 1 month to 13 years old. In 4 cases flap coverage were performed due to acquired posttraumatic hand deformity, in 6 cases reconstruction was assumed for congenital hand deformities. Combined procedures consisted of posterior interosseous artery flap coverage and other types of microsurgical reconstructions were suggested in 4 patients. Preoperative color doppler visualization of the posterior interosseous vessels were mandatory. All flaps were risen under 3.5x-4.5x magnification. Results: all flaps survived completely in 3 weeks postoperatively. There were no postoperative complications such as flap’s arterial or venous insufficiency, deep infection, or posterior interosseous nerve palsy. Nearly whole group (9 of 10 of patients and/or their parents were satisfied with the esthetic view of the reconstructed hand and donor site of the forearm 1 year postoperatively. Conclusion: posterior interosseous flap is a reliable and versatile option in pediatric hand reconstructions, providing excellent skin coverage with good color match and texture. Preservation of major vascular bundles of the forearm (radial and ulnar arteries during flap harvest gives a possibility to perform a simultaneous microsurgical reconstructions of the hand (e.g. free toe transfer.

    We report the first case of the assessment and treatment of a spontaneous patellar fracture in a patient with Goltz syndrome-a rare dermal hypoplasia. This case illustrates the non-straightforward presentation of a spontaneous patellar fracture in seemingly osteoporotic bone stock further complicated by the inability to rule out osteomyelitis. In this confusing presentation, a high index of suspicion for patella fracture should be maintained for patients with knee pain and osteoporosis on x-ray with a dysplastic syndrome.

    In 2013 the Federal Office for Radiation Protection gave the responsibility to the Department of History, Philosophy and Ethics of Medicine (Institut GTE Med) in Aachen for the project ''Creating a practical hand-out for the assessment of study results for employees of local governments'' (FM 8855). The manual serves as a practical way for the qualitative evaluation of texts for persons who deal with the topics Mobile Communication and Health (for example communities or government agencies) in their profession. The main objective of the manual is to aid users in performing a faster and more efficient evaluation of texts by answering the containing questions. This approach is purely functional and precludes the placement of deeper information. At this point the new project FM 8862 started by ''Creating a continuative brochure in addition to the hand-out for the assessment of study results''. It continued the previous project FM 8855 to further develop the information which was up to this point purely functional. The brochure presents the issues in an overall context and provides valuable background knowledge. As a result, possible users get in a more casual and clear manner a deeper understanding of the evaluating of texts. It should be possible for a user to better evaluate texts and by obtaining arguments, thus being better prepared to engage with interested Laymen in an objective discussion. The brochure was submitted together with the existing manual for a practical test, which was attended by 21 target group-specific subjects. The study tested in detail the intelligibility, clarity, applicability, and the support of the brochure. The feedback of the test participants were then used as basis for the final optimization of the brochure. Project participants belong to the Department of History, Philosophy and Ethics of Medicine and the Research Center for Bioelectromagnetic Interaction of the RWTH Aachen University (femu).

This study reports a previously healthy, 30-year-old man who came with chief complaint of acute abdominal pain to emergency room. On physical examination, abdominal tenderness and guarding were detected to be coincident with hypotension. Ultrasonography revealed mild splenomegaly with moderate free fluid in abdominopelvic cavity. Considering acute abdominal pain and hemodynamic instability, he underwent splenectomy with splenic rupture as the source of bleeding. Histologic examination showed diffuse infiltration by tumor. Immunohistochemical study (positive for S100, HMB45, and vimentin and negative for CK, CD10, CK20, CK7, CD30, LCA, EMA, and chromogranin confirmed metastatic malignant melanoma. On further questioning, there was a past history of a nasal dark skin lesion which was removed two years ago with no pathologic examination. Spontaneous (nontraumatic rupture of spleen is an uncommon situation and it happens very rarely due to neoplastic metastasis. Metastasis of malignant melanoma is one of the rare causes of the spontaneous rupture of spleen.

    Adopting a social-psychological approach, this research examines whether emotional empathy, an affective reaction regarding another's well-being, fosters hand hygiene as this affects other's health-related well-being extensively. Three studies tested this notion: (a) a cross-sectional study involving a sample of health care workers at a German hospital, (b) an experiment testing the causal effect of empathy on hand hygiene behaviour and (c) an 11-week prospective study testing whether an empathy induction affected disinfectant usage frequency in two different wards of a hospital. Self-reported hand hygiene behaviour based on day reconstruction method was measured in Study 1, actual hand sanitation behaviour was observed in Study 2 and disinfectant usage frequency in two different hospital wards was assessed in Study 3. Study 1 reveals an association of empathy with hand hygiene cross-sectionally, Study 2 documents the causal effect of empathy on increased hand sanitation. Study 3 shows an empathy induction increases hand sanitiser usage in the hospital. Increasing emotional empathy promotes hand hygiene behaviour, also in hospitals. Besides providing new impulses for the design of effective interventions, these findings bear theoretical significance as they document the explanatory power of empathy regarding a distal explanandum (hand hygiene).

    To present the results of surveys of staff, patients and visitors about their perceptions of hand hygiene behaviour before and after implementation of the Clean hands save lives campaign in New South Wales public hospitals. Pre- and post-campaign questionnaires, disseminated through project officers in each health authority, were completed by selected staff and patients/visitors in all 208 public hospitals in NSW. Combined, de-identified results for each health authority were forwarded to the NSW Clinical Excellence Commission for analysis. Awareness of campaign material; staff perceptions about their ability to maintain a high level of hand hygiene compliance before and after contact with patients; compliance self-reported by staff compared with compliance perceived by patients/visitors and compliance assessed by overt observation. Most staff and patients/visitors were aware of campaign materials. Eighty-six per cent of staff respondents (495/578) believed that placement of alcohol-based hand rub (AHR) close to the point of patient care had improved hand hygiene compliance, and 76% (510/671) believed they could sustain their level of compliance. Only 1 in 4 patients or visitors (106/397) were willing to question health care workers who appeared not to be complying with hand hygiene practices. As the first coordinated statewide campaign to modify hand hygiene culture, the Clean hands save lives campaign successfully engendered positive attitudes and dispelled negative perceptions about the onerous nature of before- and after-patient-contact hand hygiene compliance.

    Assessment of leukocyte activity with spontaneous NBT-test in influenza patients regarding the disease stage, severity, complication and concomitant diseases. 107 influenza patients aged 16-84 years were studied. 70 patients had no complications, 11 patients had early influenzal pneumonia, 26 patients had late viral-bacterial infection. Chronic concomitant diseases were diagnosed in 23 cases. Cytochemical examination of leukocyte activity was made in all the patients using spontaneous NBT-test. In mild influenza NBT-test results were within upper limits of normal value. In alleviation of the symptoms NBT-test parameters were low. In early influenzal and viral-bacterial pneumonia leukocyte activity was high and lowered to normal in late convalescence. Parameters of spontaneous NBT-test in influenzal patients were elevated depending on influenza stage, severity and complications. This fact is of differential-diagnostic importance.

  6. Spontaneous Plasticity of Multineuronal Activity Patterns in Activated Hippocampal Networks

    Full Text Available Using functional multineuron imaging with single-cell resolution, we examined how hippocampal networks by themselves change the spatiotemporal patterns of spontaneous activity during the course of emitting spontaneous activity. When extracellular ionic concentrations were changed to those that mimicked in vivo conditions, spontaneous activity was increased in active cell number and activity frequency. When ionic compositions were restored to the control conditions, the activity level returned to baseline, but the weighted spatial dispersion of active cells, as assessed by entropy-based metrics, did not. Thus, the networks can modify themselves by altering the internal structure of their correlated activity, even though they as a whole maintained the same level of activity in space and time.

    The emergence of speech and music in the human species represent major evolutionary transitions that enabled the use of complex, temporally structured acoustic signals to coordinate social interaction. While the fundamental capacity for temporal coordination with complex acoustic signals has been shown in a few distantly related species, the extent to which nonhuman primates exhibit sensitivity to auditory rhythms remains controversial. In Experiment 1, we assessed spontaneous motor tempo and tempo matching in a bonobo (Pan paniscus), in the context of a social drumming interaction. In Experiment 2, the bonobo spontaneously entrained and synchronized her drum strikes within a range around her spontaneous motor tempo. Our results are consistent with the hypothesis that the evolution of acoustic communication builds upon fundamental neurodynamic mechanisms that can be found in a wide range of species, and are recruited for social interactions.

    We aimed to investigate a potential association between B-lines and weaning failure. Fifty-seven subjects eligible for ventilation liberation were enrolled. Patients with tracheostomy were excluded. Lung ultrasound assessments of six thoracic zones were performed immediately before and at the exnd of the spontaneous breathing trial. B-predominance was defined as any profile with anterior bilateral B-pattern. Patients were followed up to 48 hours after extubation. Thirty-eight individuals were successfully extubated; 11 failed the spontaneous breathing trial and 8 needed reintubation within 48 hours of extubation. At the beginning of the T-piece trial, B-pattern or consolidation was already found at the lower and posterior lung regions in more than half of the individuals and remained non-aerated at the end of the trial. A trend toward loss of lung aeration during spontaneous breathing trials was observed only in the spontaneous breathing trial-failure group (p = 0.07), and there was higher B-predominance at the end of the trial (p = 0.01). A loss of lung aeration during the spontaneous breathing trial in non-dependent lung zones was demonstrated in subjects who failed to wean.

    Consistent hand hygiene is key to reducing health care-associated infections (HAIs) and assessing compliance with hand hygiene protocols is vital for hospital infection control staff. A new automated hand hygiene compliance system (HHCS) was trialed as an alternative to human observers in an intensive care unit and an intensive care stepdown unit at a hospital facility in the northeastern United States. Using a retrospective cohort design, researchers investigated whether implementation of the HHCS resulted in improved hand hygiene compliance and a reduction in common HAI rates. Pearson χ 2 tests were used to assess changes in compliance, and incidence rate ratios were used to test for significant differences in infection rates. During the study period, the HHCS collected many more hand hygiene events compared with human observers (632,404 vs 480) and ensured that the hospital met its compliance goals (95%+). Although decreases in multidrug-resistant organisms, central line-associated bloodstream infections, and catheter-associated urinary tract infection rates were observed, they represented nonsignificant differences. Human hand hygiene observers may not report accurate measures of compliance. The HHCS is a promising new tool for fine-grained assessment of hand hygiene compliance. Further study is needed to examine the association between the HHCS and HAI rate reduction. Copyright © 2017 Association for Professionals in Infection Control and Epidemiology, Inc.

    Effective hand hygiene is essential to prevent the spread of pathogens on produce farms and reduce foodborne illness. The U.S. Food and Drug Administration Food Safety Modernization Act Proposed Rule for Produce Safety recommends the use of soap and running water for hand hygiene of produce handlers. The use of alcohol-based hand sanitizer (ABHS) may be an effective alternative hygiene intervention where access to water is limited. There are no published data on the efficacy of either soap or ABHS-based interventions to reduce microbial contamination in agricultural settings. The goal of this study was to assess the ability of two soap-based (traditional or pumice) and two ABHS-based (label-use or two-step) hygiene interventions to reduce microbes (coliforms, Escherichia coli, and Enterococcus spp.) and soil (absorbance of hand rinsate at 600 nm [A600]) on farmworker hands after harvesting produce, compared with the results for a no-hand-hygiene control. With no hand hygiene, farmworker hands were soiled (median A600, 0.48) and had high concentrations of coliforms (geometric mean, 3.4 log CFU per hand) and Enterococcus spp. (geometric mean, 5.3 log CFU per hand) after 1 to 2 h of harvesting tomatoes. Differences in microbial loads in comparison to the loads in the control group varied by indicator organism and hygiene intervention (0 to 2.3 log CFU per hand). All interventions yielded lower concentrations of Enterococcus spp. and E. coli (P hands (P hand washing with soap at reducing indicator organisms on farmworker hands. Based on these results, ABHS is an efficacious hand hygiene solution for produce handlers, even on soiled hands.

    The relationship between spontaneous speech and formal language testing in people with brain tumors (gliomas) has been rarely studied. In clinical practice, formal testing is typically used, while spontaneous speech is less often evaluated quantitatively. However, spontaneous speech is quicker to sample and may be less prone to test/retest effects, making it a potential candidate for assessing language impairments when there is restricted time or when the patient is unable to undertake prolonged testing. To assess whether quantitative spontaneous speech analysis and formal testing detect comparable language impairments in people with gliomas. Specifically, we addressed (a) whether both measures detected comparable language impairments in our patient sample; and (b) which language levels, assessment times, and spontaneous speech variables were more often impaired in this subject group. Five people with left perisylvian gliomas performed a spontaneous speech task and a formal language assessment. Tests were administered before surgery, within a week after surgery, and seven months after surgery. Performance on spontaneous speech was compared with that of 15 healthy speakers. Language impairments were detected more often with both measures than with either measure independently. Lexical-semantic impairments were more common than phonological and grammatical impairments, and performance was equally impaired across assessment time points. Incomplete sentences and phonological paraphasias were the most common error types. In our sample both spontaneous speech analysis and formal testing detected comparable language impairments. Currently, we suggest that formal testing remains overall the better option, except for cases in which there are restrictions on testing time or the patient is too tired to undergo formal testing. In these cases, spontaneous speech may provide a viable alternative, particularly if automated analysis of spontaneous speech becomes more readily

    that embraces both. Yet, over the last years, animation and live-action footage became completely tangled in cinematic productions. Obviously, this means that each of them is just a technical strategy supported by its own specialists and as one became dominant, the other turned out to be marginal. But what...... if we could ascertain a specific ontology for animation within technology that would explain how its marginality is rooted to its essence at least in one of its forms? In this paper I will try to argue that, by overwhelming the cinematic technical standard workings with their hand, authors exposed its...

    Full Text Available Spontaneous intracerebral haemorrhage (SIH represents a severe clinical event that is associated with high rates of mortality and morbidity. Only a minority of SIH patients receive surgical treatment, whereas the majority are treated conservatively. Venous thromboembolism (VTE is one of the most common complications in SIH patients and a potential cause of death. Because of the lack of adequate evidences from the literature, the risk to benefit ratio of pharmacologic prophylaxis of VTE, represented on the one hand by hematoma enlargement and/or rebleeding and on the other hand by an expected reduction of the risk of VTE, remains controversial. Mechanical prophylaxis is a potentially safer alternative, but the efficacy of this approach is uncertain. In the absence of specific clinical guidelines containing clear-cut recommendations, physicians have insufficient tools to assist their therapeutic decisions.

    To evaluate the role of free-hand transperineal targeted prostate biopsy using multiparametric magnetic resonance imaging-transrectal ultrasound (mpMRI-TRUS) fusion in Chinese men with repeated biopsy. A total of 101 consecutive patients suspicious of prostate cancer (PCa) at the mpMRI scan and with prior negative biopsy and elevated PSA values were prospectively recruited at two urological centers. Suspicious areas on mpMRI were defined and graded using PI-RADS score. Targeted biopsies (TB) were performed for each suspicious lesion and followed a 12-core systematic biopsy (SB). Results of biopsy pathology and whole-gland pathology at prostatectomy were analyzed and compared between TB and SB. The risk for biopsy positivity was assessed by univariate and multivariate logistic regression analysis. Fusion biopsy revealed PCa in 41 of 101 men (40.6%) and 25 (24.8%) were clinically significant. There was exact agreement between TB and SB in 74 (73.3%) men. TB diagnosed 36% more significant cancer than SB (22 vs 13 cases, P = 0.012). When TB were combined with SB, an additional 14 cases (34.1%) of mostly significant PCa (71.4%) were diagnosed (P = 0.036). TB had greater sensitivity and accuracy for significant cancer than SB in 26 men with whole-gland pathology after prostatectomy. PI-RADS score on mpMRI was the most powerful predictor of PCa and significant cancer. Free-hand transperineal TB guided with MRI-TRUS fusion imaging improves detection of clinical significant PCa in Chinese men with previously negative biopsy. PI-RADS score is a reliable predictor of PCa and significant cancer.

  20. Treatment of Chronic Spontaneous Urticaria

    Science.gov (United States)

    2012-01-01

    Chronic spontaneous urticaria is defined as persistent symptoms of urticaria for 6 weeks or more. It is associated with autoimmunity in approximately 45 percent of patients. Therapy is often difficult however the initial approach should employ high-dose non-sedating antihistamines; 4-6 tablets/day may be necessary. It has been shown that the response to 4 tablets/day exceeds 3, and exceeds 2, which exceeds 1. However the dose that corresponds to the maximal dose of first generation antihistamines (hydroxyzine, diphenhydramine) used previously, is 6/day. Yet over half the patients are refractory to antihistamines and other agents should be tried next. Whereas current guidelines (published) often add leukotriene antagonists and/or H2 receptor antogonists next, these are of little utility. Likewise drugs effective for urticarial vasculitis (colchicine, dapsone, sulfasalazine, hydroxychloroquine) are effective in a small percentage of patients and no study suggests that the response rate of any of them exceeds the 30% placebo responses seen in most double-blind, placebo controlled studies. The drugs that are effective for antihistamine-resistant chronic spontaneous urticaria are corticosteroids, cyclosporine, and Omalizumab. Use of steroids is limited by toxicity. If used at all, a dose of no more than 10 mg/day should be employed with a weekly reduction of 1 mg. The response rates to cyclosporine and Omalizumab are each close to 75%. Cyclosporine can be used effectively if care is taken to monitor blood pressure, urine protein, blood urea nitrogen, and creatinine, every 6 weeks. Omalizumab has the best profile in terms of efficacy/toxicity and, once approved by federal agencies for use in chronic spontaneous urticaria, a dramatic change in the treatment paradigm, whether associated with autoimmunity or not, is predicted. A phase 3 trial is currently in place. Refractoriness to both Omalizumab and cyclosporine is expected to be less than 5 percent of patients. Other
