Abstract
UNLABELLED Previous standards for assessing the reliability of a measurement tool have lacked consistency. We reviewed the most current American Society for Testing and Materials and International Organisation for Standardisation (ISO) recommendations, and propose an algorithm for orthopaedic surgeons. When assessing a measurement tool, conditions of the experimental set-up and clear formulae used to compile the results should be strictly reported. According to these recent guidelines, accuracy is a confusing word with an overly broad meaning and should therefore be abandoned. Depending on the experimental conditions, one should be referring to bias (when the study protocol involves accepted reference values), and repeatability (sr, r) or reproducibility (SR, R). In the absence of accepted reference values, only repeatability (sr, r) or reproducibility (SR, R) should be provided. TAKE HOME MESSAGE Assessing the reliability of a measurement tool involves reporting bias, repeatability and/or reproducibility depending on the defined conditions, instead of precision or accuracy.

Abstract
Most published randomised controlled trials which compare the rates of wear of conventional and cross-linked (XL) polyethylene (PE) in total hip arthroplasty (THA) have described their use with a cementless acetabular component. We conducted a prospective randomised study to assess the rates of penetration of two distinct types of PE in otherwise identical cemented all-PE acetabular components. A total of 100 consecutive patients for THA were randomised to receive an acetabular component which had been either highly XL then remelted or moderately XL then annealed. After a minimum of eight years follow-up, 38 hips in the XL group and 30 hips in the annealed group had complete data (mean follow-up of 9.1 years (7.6 to 10.7) and 8.7 years (7.2 to 10.2), respectively). In the XL group, the steady state rate of penetration from one year onwards was -0.0002 mm/year (sd 0.108): in the annealed group it was 0.1382 mm/year (sd 0.129) (Mann–Whitney U test, p < 0.001). No complication specific to either material was recorded. These results show that the yearly linear rate of femoral head penetration can be significantly reduced by using a highly XLPE cemented acetabular component.

Abstract
Inferior vena cava (IVC) filters are widely used to prevent pulmonary embolism (PE) in patients with an absolute or relative contraindication for anticoagulants, during the peri-operative period of trauma or total joint replacement. No complication specific to the orthopaedic's aspect of this practice has been described. We report the case of a patient who had major femoral head/cup separation mimicking dislocation following revision total hip arthroplasty related to massive intra-capsular oedema produced by IVC filter thrombosis. The patient could be successfully treated non-operatively. Orthopaedic surgeons should identify and refer patients with a complicated IVC filter, to identify any migration or occlusion, and also be aware that removable filters must not be kept in situ, once the high-risk phase of developing PE is past.

Abstract
RÉSUMÉ
Cet article présente les résultats d'une revue de la documentation couvrant les années 1968 à 1993 et portant sur les liens entre la monoparentalité, la pauvreté et la santé mentale. A partir des banques de données courantes, 56 articles ont été retenus. Les mères monoparentales sont de plus en plus nombreuses et de plus en plus pauvres. Sur six variables de santé mentale répertoriées, quatre (détresse psychologique, estime de soi, sentiments de compétence et isolement psychologique) démontrent que ces mères sont en moins bonne santé mentale que les mères biparentales. L'estime de soi, la détresse et le bien-être psychologique des mères sont affectés par les variables économiques. Les résultats varient donc en fonction de la variable mesurée. Les mères monoparentales vivent plus de malaises psychologiques que les biparentales, mais elles ne semblent pas vivre plus de troubles sévères de santé mentale. Les recherches éventuelles devraient tenir compte d'un certain nombre d'aspects afin de rendre compte des liens entre la monoparentalité, la pauvreté et de la santé mentale.

Abstract
Wax sculptures contain several materials from both organic and inorganic nature. These works of art are particularly fragile. Determining their chemical composition is thus of prime importance for their preservation. The identification of the recipes of waxy pastes used through time also provides valuable information in the field of art history. The aim of the present research was to develop a convenient analytical strategy, as non-invasive as possible, that allows to identify the wide range of materials involved in wax sculptures. A multi-step analytical methodology, based on the use of complementary techniques, either non- or micro-destructive, was elaborated. X-ray fluorescence and micro-Raman spectroscopy were used in a non-invasive way to identify inorganic pigments, opacifiers and extenders. The combination of structural and separative techniques, namely infrared spectroscopy, direct inlet electron ionisation mass spectrometry and high temperature gas chromatography, was shown to be appropriate for unravelling the precise composition of the organic substances. A micro-chemical test was also performed for the detection of starch. From this study it has been possible to elucidate the composition of the waxy pastes used by three different sculptors at the end of the 19th century. Complex and elaborated recipes, in which a large range of natural substances were combined, were highlighted.

Abstract
To identify the various natural and synthetic substances used by sculptors at the end of the 19th century, several contemporary reference samples were investigated by high temperature gas chromatography (HT GC) and HT GC-MS. Using specific chromatographic conditions and minimising sample preparation, we could separate, detect and identify a wide range of biomolecular markers covering a great variety of molecular weights and volatilities, with a minimum amount of sample, in a single run. Beeswax, spermaceti, carnauba, candellila and Japan waxes as well as pine resin derivatives, animal fats, paraffin, ozokerite and stearin, used as additives in wax works of art, were chemically investigated. In the case of low volatile compounds, transbutylation was performed. The structure of long-chain esters of spermaceti was elucidated for the first time by HT GC-MS analysis. Such a method was then carried out on 10 samples collected on a statuette of Junon by Antoine-Louis Barye (Louvre Museum, Paris, France) and on a sculpture by Aimé-Jules Dalou (Musée de la Révolution Française, Vizille, France). The analytical results obtained provide new data on the complex recipes elaborated by sculptors at the end of the 19th century.

Abstract
OBJECTIVE In 2003, asplenia had involved 250000 patients in France. These patients are at risk of severe infection, mostly with capsulated bacteria as pneumococci, meningococci and Haemophilus. The higher mortality and morbidity due to infection in asplenic patient led in June 2003 a French expert committee to propose preventive management based on vaccination and antibioprophylaxis. STUDY DESIGN Update article. DATA SYNTHESIS For vaccination, two vaccines against pneumococci are available. The first one, the antipolysaccharide (Pneumo 23) is recommended for adults. It is effective for the majority of the serotypes even if its efficacy can be variable. The second one a conjugated pneumococcal vaccine (Prenevar) is used for children under two years because it has higher activity on antibiotic resistant strains therefore increasing antibiotic prophylaxis efficiency. When splenectomy is required, vaccination against pneumococci, Haemophilus (b type) and C meningococci must be performed at least 15 days before surgery, in order to get better immune stimulation. In case of emergency, vaccines have to be administrated within 30 days after surgery. Antibioprophylaxis is based on cefazolin injection before splenectomy and by postoperative intravenous amoxicillin administration. As soon as oral intake is allowed, antibioprophylaxis is continued for at least two years in adults and five years in children. Both antibiotic and vaccination have been reported to reduce pneumococcus infections.

Abstract
BACKGROUND Urinary incontinence (UI) is a common problem in elderly people, due mainly to functional impairments and concurrent medical diseases. Few studies, however, have assessed the prevalence of UI in noninstitutionalized individuals. The objectives of the present work were to estimate the prevalence of UI in a community-based population of elderly Italians and to determine the associated physical, social, and psychological factors. METHODS A random sample of noninstitutionalized men (n = 867) and women (n = 1531), aged 65 years and older, from the Veneto region of northeastern Italy, were interviewed at home, using an extensive multidisciplinary questionnaire, to assess their quality of life and social, biological, and psychological correlates. RESULTS The prevalence rate of UI was of 11.2% among men and of 21.6% among women. Among those reporting the condition, approximately 53% of women and 59% of men reported experiencing incontinence daily or weekly. Association of UI was found for participants older than 70 years in both men (odds ratio [OR] 2.49, 95% confidence interval [CI] 1.45-4.28) and women (OR 1.49, 95% CI 1.11-2.02). Three of the medical conditions investigated were associated with increases in the odds in women, namely chronic obstructive pulmonary disease (OR 1.53, 95% CI 1.11-2.12), Parkinsonism (OR 2.27, 95% CI 1.14-4.54), and hip fracture (OR 1.38,95% CI 1.02-1.88), whereas chronic diarrhea was the only condition associated with UI in men (OR 6.92, 95% CI 2.22-21.5). Participants with a physical disability were two times more likely to report incontinence, and the odds were increased by 50% in women who had sleep disturbances. CONCLUSIONS Incontinence is highly prevalent in the Italian elderly population, and several common chronic conditions are significantly associated with it. Moreover, very few people with incontinence seek health care or are aware of potential treatments.

Abstract
BACKGROUND Low back pain is a highly prevalent chronic condition, yet little is known about the disabling effects of this common problem in older adults. This study examines the relationship between the presence and severity of low back pain and disability in older women. METHODS The study population was 1,002 disabled older women participating in a population-based prospective study of disablement. Key outcome measures of disability included level of difficulty and inability to perform the following daily activities: light housework, shopping, walking one-quarter mile, climbing stairs, lifting, and activities of daily living (ADLs). RESULTS Forty-two percent of participants reported they had low back pain for at least one month in the year before baseline. The prevalence of severe back pain decreased markedly with age (10% of those > or = 85 yr versus 23% in each of the two younger 10 yr age groups). After multivariate adjustments, women with severe back pain were 3 to 4 times more likely than other women to have a lot of difficulty with light housework or shopping. There was also an increased likelihood of difficulty with mobility tasks and basic ADLs among those with severe back pain. No associations were found between back pain and being unable to perform any of the daily activities studied, indicating possible differences in disablement processes leading to functional difficulties versus functional incapacity. CONCLUSIONS There was a strong association between back pain and functional difficulties in older women, pointing to the need for further research using longitudinal methods.

Abstract
To evaluate the ability of ECG-gated spin-echo (SE)-MR imaging vs. cine-MR imaging to assess coarctation of the aorta, 11 patients aged 15-45 years, with known or suspected coarctation of the aorta, and five patients suspected of re-stenosis or postoperative false-aneurysms after coarctation repair were examined by multisection SE-MR imaging and single-section multiphase cine-MR imaging on a 1.0 Tesla device. Aortography was performed in 15, and surgery in 14 of these 16 patients. Qualitatively, the location, severity, and length of the coarctation were shown in all cases with MR imaging, as well as the relationship with the arteries arising from the aortic arch. The respective sensitivities and specificities in the assessment of severity of stenoses were 86% and 100% for SE MR images, and 100% and 100% for cine-MR images. Cine-MR imaging was superior to SE imaging in stenosis diameter assessment with contrast angiography as reference, as well as to identify the site of leakage in cases of postoperative pseudoaneurysm. Pre-stenotic dilation or post-stenotic aneurysm, collateral channels, and associated malformations were better identified on SE images. Quantitatively, a better stenosis diameter correlation was found between cine-MR images and angiography than between SE-MR images and angiography (r=0.99 vs. r=0.78; p=0.001 vs. p=0.004), related to overestimation of stenoses with SE-MR imaging. The use of a combination of spin-echo and cine-MR imaging correlates well with conventional angiographic findings in this small series of patients with coarctation of aorta or postoperative pseudoaneurysmal complications. Cine-MRI can provide anatomic information that is equivalent to angiography for surgical planning.

Abstract
BACKGROUND Most studies report that people with higher education enjoy better health and longer life. Although it is well known that most risk factors are more common among individuals with a lower level of education, the underlying mechanism of this association is not fully understood. The objective of this study was to assess the association between education, disability, and mortality. METHODS We analyzed data on 1,817 men and 1,643 women, aged 65-84 years, to assess the association of educational level with physical disability and mortality adjusting for age, sex, smoking habit, occupation, and major chronic conditions. RESULTS The association between educational level and disability was characterized by a dose-response effect, with the relative odds significantly decreased by about 30%, 60%, and 79% in those with 4 or 5, 6 to 8, and more than 8 years of education, compared to those with 3 or less years of education. Death rates were lower among persons with 4 or more years of education compared to those with less education. However, after adjusting for disability status, education was no longer associated with mortality (RR=0.97, CI=0.65-1.43). CONCLUSIONS The strong association of low education with disability found in this study may explain the inverse association with mortality reported in previous studies. Disability, indeed, seems to be the mediator between education and mortality and might be due to the higher severity level of diseases, leading to death, in the lower educated group.

Abstract
Using data from the Cardiovascular Health Study, we studied the relation between body composition (fat mass and fat-free mass, assessed by bioelectrical impedance) and self-reported, mobility-related disability (difficulty walking or stair climbing) in 2714 women and 2095 men aged 65-100 y. In a cross-sectional analysis at baseline (1989-1990), disability was reported by 26.5% of the women and 16.9% of the men. A positive association was observed between fat mass and disability. The odds ratio for disability in the highest quintile of fat mass was 3.04 (95% CI: 2.18, 4.25) for women and 2.77 (95% CI: 1.82, 4.23) for men compared with those in the lowest quintile. Low fat-free mass was not associated with a higher prevalence of disability. In a longitudinal analysis among persons not reporting disability at baseline, 20.3% of the women and 14.8% of the men reported disability 3 y later. Fat mass at baseline was predictive of disability 3 y later, with odds ratios of 2.83 (95% CI: 1.80, 4.46) for women and 1.72 (95% CI: 1.03, 2.85) for men in the highest quintile of fat. The increased risk was not explained by age, physical activity, chronic disease, or other potential confounders. Low fat-free mass was not predictive of disability. The results showed that high body fatness is an independent predictor of mobility-related disability in older men and women. These findings suggest that high body fatness in old age should be avoided to decrease the risk of disability.

Abstract
OBJECTIVES To investigate the prevalence rate of hearing impairment, assessed by both the Sanders' questionnaire and the speech audiometry test, and its association with health-related factors in the older population of the Veneto region of Italy. DESIGN A cross-sectional survey. SETTING A community-based population. PARTICIPANTS 2398 noninstitutionalized individuals aged 65 years and older residing in the Veneto region of Italy. MEASUREMENTS Prevalence rates of hearing impairment and odds ratios for its association with potential risk factors. MAIN RESULTS The prevalence of self-reported hearing impairment at home was 8.1% in men and 7.4% in women, and in a social environment it was 11.1% and 9.3%, respectively. Women were less likely to report hearing difficulties in both environments, and increased risks were found for depression, age, and poor self-rated health. Participants with diabetes or cognitive impairment had increased odds only at home, in contrast to people with a low education level, who had increased odds only in a social environment. The prevalence assessed by speech audiometry was 19% in both sexes. Increased age, diabetes, and poor self-rated health were associated with impaired speech intelligibility, cognitive impairment was associated with 4-fold increased odds among past users of alcohol, and men with a low education level were about three times as likely as others to have hearing impairment. CONCLUSIONS Speech audiometry testing detected a higher prevalence of hearing impairment than use of a self-reported questionnaire and was associated with poor self-rated health, history of diabetes, and cognitive impairment among past users of alcohol and among men with low levels of education. The association between hearing deficit and depressive symptomatology was confirmed only with self-reported hearing impairment.

Abstract
Aim of the study was investigate the cross-sectional relationship between body composition and bone mineral density (BMD) in very old men and women. The study sample consisted of 504 women and 285 men, aged 72-93 yr, participating in examination 22 (1992-1993) of the Framingham Heart Study. Total body BMD, regional BMD, and soft-tissue body composition was measured by dual-energy X-ray absorptiometry. Both muscle mass and percentage body fat were positively associated with total body BMD in women. After adjustment for age, physical activity, smoking status, estrogen use, and thiazide use, BMD increased with increasing tertile of muscle mass (p = 0.007) and with increasing tertile of percentage body fat (p = 0.0001) in women. In men muscle mass, not percentage body fat, was positively associated with BMD. After adjustment for potential confounders, BMD remained associated with muscle mass only (p = 0.02). These results were similar for leg BMD and arm BMD. The study suggests that the influence of muscle and fat mass on bone mineral density is different between very old men and women.

Abstract
BACKGROUND Low muscle mass has been assumed to be associated with disability, but no studies confirming this association have been published. High body weight and high body mass index, both rough indicators of body fatness, have been shown to increase the risk for disability; however, the specific role of body fatness has not been studied. METHODS The relations of skeletal muscle mass and percent body fat with self-reported physical disability were studied in 753 men and women aged 72 to 95 years. Cross-sectional data from biennial examination 22 (1992-1993) of the Framingham Heart Study were used. Body composition was assessed by dual-energy x-ray absorptiometry. Disability was scored as any versus none on a 9-item questionnaire. RESULTS Total body and lower extremity muscle mass were not associated with disability in either men or women. However, a strong positive association between percent body fat and disability was observed. The odds ratio for disability in those in the highest tertile of body fatness was 2.69 (95% confidence interval 1.45-5.00) for women and 3.08 (1.22-7.81) for men compared to those in the lowest tertile. The increased risk could not be explained by age, education, physical activity, smoking, alcohol use, estrogen use (women only), muscle mass, and health status. Analyses restricting disability to mobility items gave similar results. CONCLUSIONS In contrast to current assumptions, low skeletal muscle mass was not associated with self-reported physical disability. Persons with a high percent body fat had high levels of disability. Because it cannot be ruled out that persons with low skeletal muscle mass dropped out earlier in the study, prospective studies are needed to further assess the relationship between body composition and physical disability.

Abstract
Functional strabism amblyopia is no more a problem: before 2 years old, they are cured in 95%. On the other and, low vision population beyond any medical or surgical treatment is increasing dramatically: over a million persons are concerned. Low vision is usually a consequence of age related macular degeneration related to the increase of life-span. Diabetic retinopathy, severe glaucoma, vitreoretinal disorders and chorioretinal diseases are also important blindness causes. Only a psychosensorial rehabilitation allow persons to see differently by developing functional vision thanks to the development of sensorial neurophysiology and cognitive psychology. This rehabilitation can only take place in well defined institution with a polyvalent team because such institution are so rare in France (4/33 Sweden) the authors ask National Academy of Medicine to beg public authority to create low vision rehabilitation center.
