Monte Carlo simulation of neutron irradiation facility developed for accelerator based in vivo neutron activation measurements in human hand bones.

The neutron irradiation facility developed at the McMaster University 3 MV Van de Graaff accelerator was employed to assess in vivo elemental content of aluminum and manganese in human hands. These measurements were carried out to monitor the long-term exposure of these potentially toxic trace elements through hand bone levels. The dose equivalent delivered to a patient during irradiation procedure is the limiting factor for IVNAA measurements. This article describes a method to estimate the average radiation dose equivalent delivered to the patient's hand during irradiation. The computational method described in this work augments the dose measurements carried out earlier [Arnold et al., 2002. Med. Phys. 29(11), 2718-2724]. This method employs the Monte Carlo simulation of hand irradiation facility using MCNP4B. Based on the estimated dose equivalents received by the patient hand, the proposed irradiation procedure for the IVNAA measurement of manganese in human hands [Arnold et al., 2002. Med. Phys. 29(11), 2718-2724] with normal (1 ppm) and elevated manganese content can be carried out with a reasonably low dose of 31 mSv to the hand. Sixty-three percent of the total dose equivalent is delivered by non-useful fast group (> 10 keV); the filtration of this neutron group from the beam will further decrease the dose equivalent to the patient's hand.

Kinematics of the fingers and hands during computer keyboard use.

BACKGROUND: Although there has been extensive research about the kinematics of the neck, arm, and wrist during computer keyboarding, there is almost no information concerning the kinematics of the fingers, thumbs, and hands. The purpose of this descriptive study was to establish normative values of the kinematics of the fingers and hands during computer keyboard use. METHODS: This study describes the angles, angular velocities, and angular accelerations of the metacarpophalangeal joints and proximal interphalangeal joints for the right and left hands of 20 computer keyboard users during a word-processing task. A new kinematic variable for computer keyboard use, hand/wrist displacement, is also defined and examined. Hand/wrist displacement refers to the translational movements of the hands in which the entire hand is repositioned to strike the keys. Kinematics of both hands of the keyboard users were captured using a three-dimensional motion capture system. FINDINGS: Metacarpophalangeal joint kinematics in flexion/extension and abduction/adduction are reported during typing. Proximal interphalangeal joint kinematics in flexion/extension are also reported. The means and standard deviations for finger postures, velocities and acceleration were generally not significantly different between the right and left hands, with the exception of the 1st digit (thumb). Hand/wrist displacement was significantly different between the right and left hands for side to side movements. Differences in kinematics among the fingers are discussed in view of their potential to be a risk factor for musculoskeletal disorders. INTERPRETATION: This study establishes baseline understanding of the kinematics of computer keyboard use. This information will be useful in future studies of potential risk factors associated with keyboard use.

Anarchic hand syndrome: bimanual coordination and sensitivity to irrelevant information in unimanual reaches.

Anarchic hand syndrome is characterised by unintended but purposeful and autonomous movements of the upper limb and intermanual conflict. Based on predictions of internal models of movement generation, we examined the role of visual cues in unimanual and bimanual movements in a patient with anarchic hand syndrome and in a matched control. In Experiment 1, participants made unimanual movements in a sequential button-pressing task. The cue for the next target in a sequence appeared either prior to (exogenous) or after (endogenous) the initiation of movement. For the patient, performance of the anarchic left hand was selectively impaired in the endogenous condition. In Experiment 2, participants made unimanual movements on a digitising tablet to a target, which appeared either alone or with a distractor. While the presence of a distractor was associated with increased Initiation time in general, the patient's anarchic left hand was particularly vulnerable to disruption by the distractor. The findings of Experiments 1 and 2 indicate excessive reliance on salient environmental stimuli for movement production in anarchic hand syndrome. We conclude that in AHS goal-directed actions of the affected limb are particularly vulnerable to disruption by non-relevant information. Finally, in Experiment 3, participants performed unimanual and mirror-image bimanual movements on a digitising tablet to targets in the left or right hemispace. Coupling of the parameters of the two hands was evident such that, compared with a unimanual baseline, Initiation time of the intact right hand deteriorated while it improved for the anarchic left hand.

Dermal tolerance of Sterillium, a propanol-based hand rub.

Alcohol-based hand rubs have been used for hygienic hand disinfection in hospitals for decades. In order to achieve good compliance with hand hygiene practices in the healthcare setting, dermal tolerance of a hand rub product is crucial. Sterillium, which is used in many European countries for hygienic hand disinfection, is based on iso-propanol, n-propanol and mecetronium etilsulphate. The potential for dermal irritation and sensitization of commercially available propanol-based hand rubs containing emollients has not been studied systematically. We therefore studied the dermal tolerance of Sterillium in a repetitive occlusive patch test on 55 subjects. Sterillium was applied to one site on the back under an occlusive patch during an induction phase (total of nine applications over a three-week period) and two weeks later to a virgin site on the back during a challenge phase (one application). Twenty-four hours after removal of the patches (induction phase and challenge phase), and in addition, after 48 and 72 h (challenge phase), the sites were graded for skin reactions using a standardized scoring scale. In the induction phase, two of the 55 subjects had a barely perceptible minimal erythema at one of nine time points. The remaining 53 subjects had no skin reaction at any time. In the challenge phase, all 55 subjects had no skin reaction at all. The absence of significant reactions with respect to severity and frequency demonstrates the favourable dermal tolerance of the hand rub product. The lack of irritation or sensitization potential could enhance compliance with hand hygiene among healthcare workers.

The six golden rules to improve compliance in hand hygiene.

Improvement of compliance in hand hygiene is probably the most effective step in reducing the incidence of nosocomial infections (NI). But improvement of compliance is known to be complex. Six possibilities for improving compliance are available although some of them may be difficult to carry out. Rule 1: Select an alcohol-based hand rub which has a good skin tolerance and is acceptable to health care workers to use. This has been shown to improve compliance. Rule 2: The hand rub shall be easily available. Wall dispensers near the patient and pocket bottles may well help. Other possibilities should be assessed locally. Rule 3: Implement teaching and promotion of hand hygiene, which has been shown to be very effective. This is may be the most effective tool but will cost time and money. If money is a problem, rule 4 may be the solution. Rule 4: Create a hospital budget which covers all costs involved with preventable nosocomial infection. Combine it with the budget for hand hygiene products. Even a small number of prevented NI largely outweighs the cost of effective hand hygiene products. Rule 5: Get senior staff to set a good example in order to motivate junior staff, because negligence in hand hygiene appears to correlate with the number of professional years. Rule 6: Have the patient-staff ratio well balanced. It has been shown that staff shortage decreases hand hygiene compliance. Other factors may be important as well, but implementation of these 6 golden rules could be an effective step into the right direction.

Hand hygiene compliance in healthcare workers.

The 'clean-your-hands' campaign has now been introduced into hospitals in England but it was initially piloted in six acute trusts. The campaign was multi-modal and aimed to improve hand hygiene compliance. This review reports the findings from one of the trusts involved in the pilot. The campaign consisted of a toolkit that included placing alcohol hand rub beside patients, along with posters and supporting marketing materials. A guide to implementation and a strategy aimed at increasing patient information and empowerment was also initiated. In order to assess the success of the campaign, audits of hand hygiene in healthcare workers were conducted over a six-month period. Additionally, data were obtained from staff surveys, patient surveys, usage levels of alcohol hand rub and interviews with the on-site lead. The local campaign indicated that a multi-modal campaign induced a marked increase in hand hygiene compliance (from 32% to 63%), with 74% of staff reporting increased compliance throughout the campaign. Usage of alcohol hand rub increased by 184%. The majority of patients indicated that the public should be actively involved in helping healthcare staff to improve their hand hygiene.

Hand injuries at a British Military Hospital on operations.

The nature of military medical support necessarily changes in the transition from war fighting to the post-conflict phase. This paper examines the activity in the only British Military Hospital serving a multi-national divisional area in Iraq over 2004 during this post-conflict phase. Hand injuries were common and formed a large proportion of the workload seen at the military field hospital on operations. The overwhelming majority of hand trauma resulted in soft tissue injury. There was a clear predisposition to hand trauma for males, manual workers, combat soldiers and engineers/mechanics. While most hand injuries do not require surgical intervention, they impact on the effectiveness of the military population as a result of the large proportion of patients who are placed on restricted duties following hand trauma, 157 of 241 in this study, and the number of soldiers who require aeromedical evacuation for further treatment, 38 of 360 in this study. These injuries require that military surgeons and emergency physicians should be experienced in the initial management of hand trauma and hand trauma should be a core component of their training. The skills of the specialist hand surgeon may be required for definitive management of these injuries at a later stage.

The effect of short-term dependency and immobility on skin temperature and colour in the hand.

The effects of short-term dependency and immobility on skin temperature were assessed in two experiments. In the first study, ten volunteers hung their left arm dependent and motionless while using their right hand for light office work. After 30 minutes, the dependent left hands were cooler (mean=0.9 degrees C: 95% CI=0.7-1.1) than the active right hands and exhibited a deeper colour with significantly increased green intensity (P=0.03) as assessed on digital images. In the second study, seven volunteers submerged both their hands in water at 15 degrees C for 15 minutes. The left arm was then left dependent and motionless while the right hand was placed on the table and its fingers were flexed and extended every 10 seconds. The left hands remained cooler than the right and were a median of 3.6 (range 2.9-4.5) degrees C cooler after 60 minutes. These studies demonstrate that skin temperature and colour differences between the hands, which are sometimes used to support the diagnosis of CRPS-1, can be produced and maintained by short-term immobility and dependency of the hand.

Systematic review of therapies for osteoarthritis of the hand.

OBJECTIVE: To systematically review published randomized controlled trials (RCTs) evaluating pharmacological and non-pharmacological therapies in patients with hand osteoarthritis (OA), with an emphasis on trial methodology. METHODS: RCTs published between 1966 and August 2004 were identified by searching several electronic data sources as well as by searching reference lists. Details of study demographics, methodology, quality and outcomes were analyzed. A meta-analysis was planned, if feasible. RESULTS: Thirty-one RCTs evaluating various pharmacological and non-pharmacological therapies in hand OA were analyzed in this systematic review. When compared with hip and knee OA, there are surprisingly few published RCTs in hand OA. Generally, these RCTs are of low quality. RCTs are weakened by a lack of consistent case definition and by a lack of standardized outcome assessments. The methods used for randomization, blinding, and allocation concealment were rarely described. The number and location of symptomatic hand joints per treatment group at baseline was usually not stated. The number and location of evaluated hand joints at the end of the study was also usually not stated. A meta-analysis could not be performed since most of the treatments studied did not have more than one identical comparison to allow pooling of the data. CONCLUSION: It is apparent that hand OA is a more complex area in which to study the efficacy of therapies when compared to hip and knee OA. Consensus guidelines are urgently needed to help improve the design and conduct of RCTs in hand OA. Additional RCTs of high quality that follow consensus recommendations are needed to evaluate the wide range of possible therapeutic options available for patients with hand OA.

Performance of the Norwegian version of AUSCAN--a disease-specific measure of hand osteoarthritis.

OBJECTIVE: To examine the performance of the Norwegian version of the AUSCAN Index as a disease-specific health status measure in patients with hand osteoarthritis (OA). METHODS: One hundred and ninety-nine patients with clinical hand OA (mean (SD) age 61.7 (5.7) years, 18 (9%) males) underwent a comprehensive examination including joint status, examination of grip strength and completion of several self-reported health status questionnaires. The Australian/Canadian OA hand index (AUSCAN) captures three different dimensions of hand OA: pain (5 items), stiffness (1 item), and difficulties with daily activities (9 items). Our pre-study hypothesis was to identify AUSCAN as a specific hand measure with strong correlations to hand measures and lower correlations to other general measures of health. RESULTS: Patient completion of the AUSCAN Index was similar or better than other measures. The internal consistency of the AUSCAN was excellent. The pain and physical dimension of AUSCAN correlated substantially to each other and moderately to the stiffness scale. The AUSCAN physical scale correlated moderately to substantially to other measures, the highest correlation being seen with the Arthritis Impact Measurement Scale (AIMS) 2 hand and finger function scale (r=0.73). The standardised differences between patients with and without radiographic abnormalities were numerically larger for the AUSCAN pain and physical scales than for other measures. CONCLUSION: The Norwegian version of the AUSCAN has an acceptable clinimetric performance and is a suitable tool for assessment of hand OA.

fMRI signal decreases in ipsilateral primary motor cortex during unilateral hand movements are related to duration and side of movement.

Interactions between the primary motor cortices of each hemisphere during unilateral hand movements appear to be inhibitory, although there is evidence that the strengths of these interactions are asymmetrical. In the present study, functional magnetic resonance imaging (fMRI) was used to investigate the effects of motor task duration and hand used on unilateral movement-related BOLD signal increases and decreases in the hand region of primary motor cortex (M1) of each hemisphere in six right-handed volunteers. Significant task-related BOLD signal decreases were observed in ipsilateral M1 during single and brief bursts of unilateral movements for both hands. However, these negative-to-baseline responses were found to intensify with increasing movement duration in parallel with greater task-related increases in contralateral M1. Movement-related BOLD signal decreases in ipsilateral M1 were also stronger for the right, dominant hand than for the left hand in our right-handed subjects. These findings would be consistent with the existence of interhemispheric interactions between M1 of each hemisphere, whereby increased neuronal activation in M1 of one hemisphere induces reduced neuronal activity in M1 of the opposite hemisphere. The observation of a hemispheric asymmetry in inhibition between M1 of each hemisphere agrees well with previous neuroimaging and electrophysiological data. These findings are discussed in the context of current understanding of the physiological origins of negative-to-baseline BOLD responses.

A simulation of hand impairments: effects on upper extremity function and implications toward medical impairment rating and disability determination.

OBJECTIVES: To determine whether simulation of significant impairment of the hand will have a predictable impact on degree of functional loss at the wrist and hand. DESIGN: Single subject repeat measures using before-after trial comparisons and healthy volunteer subjects. SETTING: Occupational therapy section of a large academic medical center. OTHER PARTICIPANTS: Twenty adult volunteer student subjects from an occupational therapy education (OTE) department were included. All were between ages 18 and 43 years, right hand dominant, and in excellent general health. There were 19 women and 1 man, reflecting gender distribution of the OTE student body. INTERVENTION: A simulated fusion of the carpometacarpal (CMC) joint of the thumb was achieved by immobilization in an individually fabricated splint designed to maximally restrict motion at the first CMC joint. Impairment ratings (baseline vs splinted) according to the AMA Guides were obtained by Greenleaf testing, and upper extremity function was quantitatively assessed before and after splinting. MAIN OUTCOME MEASURES: Measures of upper extremity function included grip and pinch strength, wrist torque, and speed of performance on the Valpar Small Tools test, Jebsen Hand Function test, and an exploratory measure, the Functional Life Activity Test (FLAT). RESULTS: Significant impairments were achieved for all subjects after splinting and according to Greenleaf testing. Splinting resulted in significant reductions in grip and pinch strength, wrist torque, and significant slowing of performance on the Valpar, Jebsen, and FLAT tests. Regressions of degree of impairment on degree of functional loss after splinting, and according to each of the above measures, were not significant. CONCLUSIONS: Impairment of the hand was simulated to a mild-to-moderate degree as measured according to the AMA Guides. This imposed significant reductions in motion at key joints of the wrist and hand as well as significant reductions in grip and pinch strength and wrist torque. A corresponding and significant slowing of performance on a variety of measures of upper extremity function of an industrial and nonindustrial nature was also seen. However, and for the first time, correlation and regression reveals that it is not possible to predict degree of functional loss attributable to degree of impairment for the hand. It thus appears that, for mild-to-moderate clinical impairments, the associated impairment rating is a poor estimator of functional loss at the hand and should be used cautiously, if at all, as a criterion for disability determination.

Implanted functional electrical stimulation hand system in adolescents with spinal injuries: an evaluation.

OBJECTIVE: To study the utility and functional benefits of an implanted functional electrical stimulation (FES) system for hand grasp and release in adolescents with tetraplegia secondary to spinal cord injuries. DESIGN: Intervention study with before-after trial measurement with each subject as his or her own control. SETTING: Nonprofit pediatric orthopedic rehabilitation facility specializing in spinal cord injury. PARTICIPANTS: A convenience sample of five adolescents between 16 and 18 years of age with C5 or C6 level tetraplegia at least 1 year after traumatic spinal cord injury. Key muscles for palmar and lateral grasp and release were excitable by electrical stimulation. INTERVENTIONS: A multichannel stimulator/receiver and eight electrodes were surgically implanted to provide stimulated palmar and lateral grasp and release. In conjunction with implantation of the FES hand system, surgical reconstruction in the form of tendon transfers, tendon lengthenings and releases, and joint arthrodeses was performed to augment stimulated hand function. Rehabilitation of the tendon transfers and training in the use of the FES hand system were provided. MAIN OUTCOME MEASURES: Measurements of pinch and grasp force, the Grasp and Release Test (GRT), and an assessment of six activities of daily living (ADL) were administered before implantation of the FES hand system and at regular follow-up intervals. Results of the stimulated response of individual muscles and surgical reconstruction were evaluated using standard and stimulated muscle testing techniques and standard assessment of joint range of motion. All subjects completed followup testing. RESULTS: Lateral and palmar forces were significantly greater than baseline forces (p = .043). Heavy objects on the GRT could only be manipulated with FES, and FES increased the level of independence in 25 of 30 ADL comparisons (5 subjects, 6 activities) as compared to baseline. After training, FES was preferred in 21 of 30 comparisons over the typical means of task completion. Of the 40 electrodes implanted, 37 continue to provide excellent stimulated responses and all of the implanted stimulators have functioned without problems. The surgical reconstruction procedures greatly enhanced FES hand function by either expanding the workspace in which to utilize FES (deltoid to triceps transfer), stabilizing the wrist (brachioradialis to wrist extensor transfer), or stabilizing joints (intrinsic tenodesis transfer, FPL split transfer). CONCLUSION: For five adolescents with tetraplegia, the combination of FES and surgical reconstruction provided active palmar and lateral grasp and release. Laboratory-based assessments demonstrated that the FES system increased pinch force, improved the manipulation of objects, and typically increased independence in six standard ADL as compared to pre-FES hand function. The study also showed that the five adolescents generally preferred FES for most of the ADL tested. Data on the benefits of the implanted FES hand system outside of the laboratory are needed to understand the full potential of FES.

Alien hand syndrome: influence of neglect on the clinical presentation of frontal and callosal variants.

Three patients with mesial frontal and extensive callosal lesions due to anterior cerebral artery infarction manifested an alien hand syndrome (AHS) with varied features. Patient 1 with left hemispheric lesion showed right hand's impulsive reaching and grasping and left hand's antagonistic movements to the right (intermanual conflict; IMC). Patients 2 and 3 with right hemispheric lesion manifested a left hemihypokinesia which was thought to have suppressed the frequency and amplitude or even the occurrence of left hand's reaching and grasping. IMC and other left hand's non-antagonistic, irrelevant movements to the right remained. Because the term "IMC" is often misused and not strictly defined, its association with right hand's reaching and grasping is quite uncommon, its significance as a sign of callosal disconnection is not well validated, and because left hand's reaching and grasping tend to be suppressed by motor neglect, a trend may then develop for the right hand to be the sole focus of pathological behaviour in patients with the so-called frontal AHS (Feinberg, Schindler, Flanagan et al., 1992).

Hand preference and performance in 20 pairs of monozygotic twins with discordant handedness.

The differences between right (RH) and left (LH) handers reported in the literature on fine motor tasks, has traditionally been interpreted relative to purported functioning of the cerebral hemispheres. However, conclusive evidence for performance differences which are intrinsic to handedness per se is difficult to obtain unless left and right handers are compared who are similar in their genetic and environmental background. The present study therefore, employed a monozygotic (MZ) twin design which minimizes differences in genetic variation between the two groups. Forty female monozygotic twins (20 pairs) were selected on the basis of discordance of writing hand. Their laterality preferences were assessed and they were tested for differences on hand performance tasks (dot filling, finger tapping, and peg moving). The results revealed that on the hand and foot preference inventories, the right-handers were more strongly lateralized than their left-handed sisters, and that the left-handers had greater variation in their laterality scores. There were substantial correlations between preference and performance scores. The analyses not only revealed the obvious strong main effects of writing hand on performance tasks, but interaction effects of handedness on the peg-moving task. The dot filling task differentiated the writing versus non-writing hand considerably better than either of the other two performance tasks. However, no evidence was found to indicate that twins who wrote with their left hands showed poorer performance than their right-handed twin sisters.

Hand preferences in the skilled gathering tasks of mountain gorillas (Gorilla g. berengei).

Manual dexterity of 44 wild gorillas of all ages and both sexes was investigated on six naturally acquired feeding tasks of varied logical structure, which included multi-stage and bimanually coordinated procedures. At least 400 min observation of feeding per animal, and analysis at the level of bouts rather than individual actions, can be expected to produce statistically robust results; 22 years background data allowed effects of genealogy and injury to be investigated. Five tasks elicited very strong hand preferences in most animals (weakest on the simplest task), while one was usually performed with a strategy in which left and right hands were used symmetrically; the preferences were fully established at 3 years old. Preferences were highly correlated within each of two sets of tasks, but between the two sets there was no correlation across animals in direction or strength of preference. No population trends towards left or right handers were found in either set of tasks, or both sets pooled; distributions were U-shaped and approximately symmetric, with a slight bias towards right-handed fine manipulation in one set of tasks. Processing efficiency was only slightly greater with the preferred hand, and similar in left- and right-handed animals. Neither direction nor strength of hand preference showed a tendency to run in families, but females showed greater strength of preference. Major injury masked strong hand preference, but injuries could not account for the overall distribution of preference; instead this may reflect inbreeding. Feedback acting on initially random hand choices, and imitation at the "program" level rather than slavish copying of acts, are proposed to account for the results.

Effects of age and race on skin condition and bacterial counts on hands of neonatal ICU nurses.

OBJECTIVE: The purpose of this study was to assess the relationship between demographic factors such as age and race and skin condition and bacterial counts on hands of nurses. METHODS: Nurses (n = 111) working in 1 of 2 neonatal ICUs in New York City were surveyed regarding reported hand care practices and demographics, the condition of their hands was assessed by a trained observer and by themselves using validated instruments, and a hand culture was obtained. RESULTS: There were no significant differences in any skin care practices by race, but nurses who wore powder-free gloves were significantly younger than those who did not (P =.004). There were no significant differences in bacterial counts on hands of black or white nurses (mean log colony-forming units 3.49 and 3.61 respectively, P =.63) and no significant correlation between age and microbial counts (r = 0.04, P =.72). In a logistic regression analysis, race, but not age, was a significant predictor of skin health. By both observer (P =.02) and self-assessment (P =.004) black nurses had healthier skin. CONCLUSION: Physiochemical differences in skin associated with demographic factors such as age and race may be exacerbated among those in disciplines such as nursing, for whom the skin of the hands is continually stressed by occupational practices such as frequent hand hygiene. Such demographic factors need be considered when assessing skin condition and when advocating for appropriate strategies to maximize skin health. The recommendations of the new CDC Hand Hygiene Guideline for Healthcare Settings(23) regarding maintaining skin health and providing moisturizers and products that are milder to the skin are timely and should be followed.

Prevalence and correlates of skin damage on the hands of nurses.

OBJECTIVE: To describe the prevalence and correlates of skin damage on nurses' hands. DESIGN: Prevalence survey using self-report questionnaire of hand care regimens, problems, and skin condition, and visual examination of the hands at 30X magnification by trained investigators to evaluate degree of skin scaling. SETTING: Four hospitals: two in the Mid-Atlantic and two in the northern United States. PARTICIPANTS: Convenience sample of 410 nurses working 30 hours or more per week in acute care units. OUTCOME MEASURES: Damage to skin of the hands. RESULTS: Approximately one fourth of subjects (n = 106) met the criteria for currently damaged hands; 85.6% (n = 351) reported ever having skin problems. Damage was not correlated with age (p = 0.43), sex (p = 0.14), or skin type (p = 0.25), type of soap used at home (p = 0.58), reported duration of handwashing (p = 0.12), or glove brand (p = 0.90), but was significantly correlated with the type of soap used at work (p = 0.01), number of hand washes per shift (p = 0.0003), number of times gloves were worn (p = 0.008), and study site (p = 0.009). Variables significantly predictive of skin damage in a logistic regression analysis were type of soap used at work and number of times gloves were worn (p = 0.04). Geographic location was not a factor, because both the highest and lowest prevalence of skin damage occurred in the northern study institutions. CONCLUSIONS: Damage to skin of the hands is a common and potentially serious problem among nurses, and is associated with gloving and handwashing practices rather than with geographic or demographic factors. Efforts to improve skin condition must focus on improving products and identifying any interactive effects between hand care products and glove materials and brands.
