Only few studies have investigated the use of HA in elderly subjects and there are no data in very elderly subjects. We assessed the prescription of HA and analyzed the relationship between such prescriptions and frailty markers among persons aged 80 and more in an observational study. We recorded the prescriptions for 13,211 patients aged 80-109 years and affiliated to the "Mutualité-Sociale-Agricole (MSA)" of Burgundy over a 1-month period. The prescription of a HA among all included patients, and the existence of serious long-term disease(s) (LTD), polypharmacy or a prescription of cardiovascular drugs among patients receiving a HA were recorder. Among the 13,211 patients, 3412 aged 80-98 years were treated with an HA. The main HA were statins (70.4%), and fibrates were used in 27.3% of cases. Of these 3412 patients, 2250 had one or several LTD mainly coronaropathy, hypertension, diabetes mellitus or peripheral artery disease. The mean number of drugs per prescription was 6.37. Among subjects treated with HA, 40% also received antiplatelets, 35.6% β-blockers and 30% inhibitors of the renin-angiotensin system. For 99% of the patients, the prescription of HA was a renewal. Prescribers were mainly general practitioners (96.8%). Statins are the most widely prescribed HA even among very elderly subjects. However, after 80 years the prescription of HA, mainly statins, decreases with aging. This could be explained by polypathology, polypharmacy and the deterioration in metabolic functions which are markers of frailty. This study should encourage research into the use of statins in very elderly subjects., (Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.)

Objective: The aim of this study was to identify the factors associated with differences between how Alzheimer's disease (AD) patients and their caregivers rate the patient's health-related quality of life (QoL)., Methods: Cross-sectional, multicentre study. Patients were 65 years or more, suffering from mild to moderate AD, native French speakers, with a main caregiver. Interrater agreement of the QoL-AD was assessed using the intraclass coefficient. A generalised linear model was used to identify factors related to the difference in health-related QoL scores between patients and their caregivers., Results: The 122 patients of the study were 82 ± 6 years old and mainly women (69%). Independent factors related to the difference between patients and caregivers were: Mini Mental State Exam score (β = 0.32; 95% CI = 0.05-0.59); instrumental activities of daily living score (β = -0.61; 95% CI = -1.14 to -0.07); total Neuropsychiatric Inventory score (β = 0.10; 95% CI = 0.05-0.59), and Zarit's burden score (β = 0.09; 95% CI = 0.01-0.17)., Conclusion: Practitioners must take into account the trend towards underestimation when health-related QoL is rated by caregivers or proxies., (Copyright © 2012 S.

Background: There are currently no internationally agreed recommendations for the management of adjuvant chemotherapy in women aged >70 years with high-risk breast cancer. The purpose of this study was to assess the feasibility and the tolerance of adjuvant weekly sequential epirubicin-paclitaxel combination in this setting., Patients and Methods: From 2005 to 2009, 59 women over 70 years of age with operable breast cancer and who required adjuvant chemotherapy were proposed weekly sequential epirubicin-paclitaxel chemotherapy schedule, and were prospectively registered. Compliance and treatment tolerance were studied. We also report preliminary results of disease-free survival (DFS) and overall survival (OS)., Results: Weekly sequential epirubicin-paclitaxel was well tolerated. No grade 4 adverse event occurred. No secondary malignancy was observed. Compliance with chemotherapy was good: 95% of patients received the six planned cycles. After a median follow-up of 24 months, median DFS and OS were not reached, there were only three relapses, and two cancer-related deaths were reported., Conclusion: This study conducted in patients over 70 years of age demonstrates the feasibility of weekly adjuvant chemotherapy including anthracyclines and taxanes in a sequential schedule. This regimen is safe in terms of hematologic, nonhematologic, and cardiac toxicities, and showed encouraging efficacy, justifying further studies in geriatric patients., (Copyright © 2011.

Background: Achromobacter xylosoxidans (AX) is a non-fermentative aerobic gram-negative bacillus. It is an opportunistic pathogen and the causative agent of various infections. We report an original case of late posttraumatic meningitis due to AX denitrificans., Case Report: An 83-year-old man was hospitalized for acute headache, nausea and vomiting. The emergency brain computer tomography (CT) scan did not reveal any anomaly. In his medical history, there was an auditory injury due to a cranial trauma incurred in a skiing accident 60 years earlier. Cytobiochemical analysis of the cerebrospinal fluid (CSF) revealed increased levels of neutrophils and proteins. The CSF bacterial culture was positive: the Gram stain showed a gram-negative bacillus, oxidase + and catalase +, and the biochemical pattern using the API 20 NE strip revealed AX dentrificans. Late posttraumatic meningitis on a possible osteomeningeal breach was diagnosed even though the breach was not confirmed because the patient declined a second brain CT scan. The patient was successfully treated with meropenem., Conclusions: This report demonstrates the importance of searching for unusual or atypical organisms when the clinician encounters meningitis in a particular context, as well as the importance of adequate follow-up of craniofacial traumas.

Churg-Strauss Syndrome (SCS) is a systemic vasculitis associated with asthma and eosinophilia. The aim of our work is to describe this pathology in the Burgundian population in France. We counted from the hospitalisation data-processing summaries, the whole of the SCS hospitalised in Burgundy between 1998 and 2008. During the follow-up, the clinical and paraclinical characteristics of every patient were collected. The average prevalence is of 11.3 per million inhabitants and the incidence is of 1.2 new cases per million inhabitants per annum. There exists however, a great prevalence disparity and incidence amongst the various departments of the area. The patient's average follow-up is of 7.7 years. In 23% of the cases one finds a starting factor for vasculitis. The delay between the first signs and the diagnostic is an average of 61 months. The ANCA are positive in 26% of cases and of anti-myeloperoxidase specificity in 83% of cases (P < 0.001). The most profitable biopsies are essentially cutaneous and neuromuscular. At the diagnostic, two-third of the patients have had a treatment adapted according to the current recommendations based on the Five Factor Score. The remission rate within a 1-year period is of 77%. The remission is strongly correlated to the therapeutic protocol associating corticoids and cyclophosphamide (P < 0.05). In conclusion, the prevalence of SCS in our area is similar to that observed in other European regions. However, this vasculitis remains a difficult and often a tardive diagnostic pathology.

Background: End stage dementia is a particularly difficult aspect of care for patients with Alzheimer's disease and related dementias. In care institutions, caregivers and family are concerned by treatment decision-making for an acute life threatening complication occurring in Alzheimer patients at the end of life. How should the best treatment pathway be decided: to treat or not to treat? Which arguments are used for decision-making? These are mainly ethical questions which are currently difficult to express and investigate., Methods/design: Cross sectional multicentre study of clinical cases involving 67 health centres (university hospitals, general hospitals, local hospitals and homes for the elderly) in the east of France. The method was based on the "card sorting" technique, with a set of 36 cards, each labelled with a different item relating to arguments for treatment decision-making. For each clinical case, medical staff and carers expressed in a meeting the pieces of information which they believed had been taken into account in the decision. Each participant received a card game, selected fewer than ten and ranked them according to the importance they attached to each one. All selected cards were then put on the table anonymously for participants, respecting the order of importance of the cards in each pile. Lastly, all games were photographed together in order to analyse occurrence and order frequencies. The cards were then classified on the table by frequency to open the discussion. Discussion time, which was conducted by the head carer of the department, concerned the clinical situation of the patient based on the shared responses., Discussion: During team meetings, the "card sorting" method was quickly adopted by professionals as a tool to assist with discussion beyond the context of the study. The participants were not compelled to mention their feelings in relation to a case, and it is significant that the anonymity which we tried to maintain so that each person felt "listened to" without value judgement was very often discarded by the individuals themselves.

We investigated the effect of aging on the ability to mentally simulate/plan a complex sequential action of the whole body, namely "rising from the floor". Forty-four non-demented elderly people (mean age: 85.2±5.5 years) and 20 young people (mean age: 26.6±4.9 years) were included in the study. They were required to put in order six images representing the main movements necessary to get up from a sitting position on the floor. We showed that older subjects had poorer performance-both in terms of proportion of success and response time-than their younger counterparts. These results are in line with previous findings showing age-related alterations in action simulation/action planning processes, and highlight the fact that elderly people have particular difficulties when the action to mentally simulate is complex., (Copyright © 2009 Elsevier Ireland Ltd.

Introduction: Heart manifestations of Churg-Strauss syndrome (CSS) are varied. In the early stages of the disease, it is difficult to distinguish between lesions that are specific to CSS and those of other etiologies. The aim of our work was to compare the characteristics of patients with heart manifestations linked or not to Churg-Strauss syndrome., Material and Methods: We recorded all clinical symptoms of patients with CSS hospitalized between 1998 and 2008 in Burgundy, France, and determined the possible relationships between heart symptoms and CSS., Results: From a cohort of 31 patients, we found 20 with heart lesions. When heart lesions were present, we noted fewer initial symptoms of digestive disorders (p<0.05), lower levels of lung infiltrates and fewer anti-MPO pANCA (p<0.05). Heart lesions were linked to CSS in 75% of cases. Their patients were thus younger than those in the other cardiac patients (p<0.05), were more likely to have clinical manifestations of heart involvement at diagnosis, were less likely to have lung infiltrates on the X-ray at diagnosis and during flare-ups and less likely to have lung abnormalities on X-rays during flare-ups (p<0.05) and higher level of leucocytes and eosinophils at diagnosis., Conclusion: Heart lesions directly attributable to CSS are frequent, severe and probably underestimated. A specific physiopathology that is not mediated by ANCA seems to be involved in the genesis of CSS-related heart lesions.

PDS is a geriatric affliction, described in 1999, characterized by postural impairments, including backward disequilibrium, freezing, a deterioration in the ability to anticipate postural adjustments, anxiety and fear of falling, inducing loss of autonomy. This study compared 10 subjects suffering from PDS, aged 87.3+/-4.9 years, with 10 control subjects, aged 85.4+/-7.9 years concerning postural control (body sway amplitude). In all participants, postural control was assessed using the SwayStar system in natural (spontaneous) and standardized stances, eyes open and eyes closed over a period of 40 s. It was found that: (1) with eyes open, subjects with PDS showed greater body sway amplitude than did controls whatever the position (natural or standardized) and the plane (sagittal or frontal) considered (F(1,16)=6.05; p=0.026), (2) with eyes closed, subjects with PDS showed greater body sway amplitude than did controls in the natural stance whatever the plane (F(1,18)=7.65; p=0.013). In conclusion, PDS has a negative effect on postural control. This data must be taken into account during the rehabilitation of patients with this syndrome., (Copyright 2009 Elsevier Ireland Ltd.

Background: For several years, the burden of stroke in very old patients has been increasing in western countries. Nevertheless, we have little information about this new challenge in individuals >or=80., Methods: We ascertained all first-ever strokes in the population of Dijon, France (150,000 inhabitants), from 1985 to 2006. The incidence of stroke, risk factors, clinical presentation, resource mobilization and 1-month outcome were evaluated in individuals >or=80 and compared to the data obtained in younger patients., Results: We collected 1,410 first-ever strokes in people >or=80 years (39%) versus 2,130 in those <80 years. The incidence was 997/100,000, and 68/100,000, respectively. Over the 22 years, the incidence of stroke in individuals >or=80 years rose significantly. A lower prevalence of diabetes, hypercholesterolemia and alcohol intake, as well as a higher prevalence of hypertension, atrial fibrillation, previous myocardial infarction and use of prestroke antiplatelet agents were noted in patients >or=80 years. The clinical presentation was severer and the 1-month outcome in terms of case fatality and handicap was worse, despite improvements observed over time. Finally, in patients >or=80 years, the use of CT scan, MRI, cervical Doppler, angiography and carotid surgery were significantly lower than for younger patients. Length of stay >30 days was more frequent, and discharge to prestroke residence was less common. However, all these improved between the first and the last study periods., Conclusions: Our findings have important implications not only for clinical management but also for initiating preventive strategies and health policy., ((c) 2009 S. Karger AG, Basel.)

Rheumatoid arthritis (RA) may include rare extra-articular manifestations, and particularly cardiopulmonary involvement. We report a 83-year-old woman, with RA, who presented with both pulmonary and heart failures that were related to the RA, resulting from the presence of mediastinal and axillary lymph nodes, and pleural and pericardial effusions. This was confirmed by the dramatic improvement after a specific treatment of RA.

Depression and behavioural and psychological symptoms of dementia (BPSD) have a significant impact on the worsening of dementia because they increase the cognitive and functional decline and they have a significant impact on the vital prognosis. Physicians should be particularly careful in the use of antidepressants in the elderly, particularly in the frail elderly. Indeed, most studies have included patients aged at least 65 years without frailty criteria, but rarely those aged over 75 years and/or frail. As they are used in clinical practice, selective serotonin reuptake inhibitors, which initially appeared to have low risks, have been associated with many and dangerous adverse effects, particularly in elderly subjects. At present, there is a lack of data to assess the benefit-risk ratio of antidepressants in the treatment of depression and BPSD in patients with Alzheimer's disease or other dementias. Among the drugs frequently used in studies in order to evaluate these indications, citalopram and moclobemide are those associated with a low risk of adverse events and a significant effectiveness on depression signs and behavioural and BPSD. It is necessary to assess the effectiveness and adverse effects of antidepressants in demented elderly subjects through several studies.

Hypertension constitutes a recognized risk factor of vascular dementia but also of Alzheimer-type dementia. Various longitudinal studies showed that midlife blood pressure level is one of the factors conditioning the onset of dementia syndrome in late life. The high risk of dementia is linked to leukoaraiosis, vascular rigidity, microcirculation disorders, oxidative stress, blood pressure fluctuations including orthostatic hypotension and strokes, all of those being associated with hypertension. Numerous clinical trials showed the positive effect of effective treatment of hypertension on the prevention of cognitive disorders and dementias. Thus, screening and early management of dementia and cognitive decline, in particular in the hypertensive subject, are essential. The Mini-Mental State Examination (MMSE) is a major first-intention screening test because it allows a full assessment of cognitive aptitudes. If cognitive decline is suspected and the MMSE score is considered to be abnormal, the elderly subject must be sent to a specialist or a referent memory centre; the MMSE is only a first stage in the diagnostic reasoning. MMSE should be included in the follow-up of all hypertensive elderly subjects and should be performed once a year by the general practitioner.

Background: The clinical characteristics of frail older patients with advanced heart failure have scarcely been studied., Objective: To describe this population and to identify some prognostic factors of mortality., Methods: 104 patients aged 75 years and older hospitalized with refractory heart failure were enrolled in a prospective multicentric study., Results: Mean age was 87.2 +/- 5.3 years. Dyspnea (79.8%), crepitant rales (76.9%) and peripheral edema (73.1%) were particularly frequent. Signs of low cardiac output such as renal insufficiency (46.9%), cutaneous low flow (40.4%), and systolic hypotension (< or =100 mm Hg) (24.3%) were observed less often. Signs of cognitive impairment including anxiety (55.4%), sleep disorders (43.7%) and delirium (35.5%) were frequent. Asthenia and chronic pain were noted in 92.3 and 37.5% of cases, respectively. Mortality rates were 32.7, 59.6 and 71.2% during hospitalization, at 6 months and at 12 months, respectively. According to the multivariate Cox model, six significant factors suggesting a poor prognosis were observed: chronic renal insufficiency, past neuropsychological pathology, long-term treatment with nitrates, presence of edema, low cutaneous flow, and pain. The ability to sit on a chair was the only significant factor associated with a good prognosis., Conclusion: Our study identified some clinical and prognostic factors which had been observed in very old patients with refractory heart failure. Pain management has to be a priority in these patients in order to improve their quality of life.

Heart rate variability (HRV), which is considered to reflect the activity of the autonomic nervous system (ANS), has been shown to decline with age. The aim of the present study was to explore cardiac ANS in older patients showing frontal-subcortical dysfunction with "Psychomotor Disadaptation Syndrome" (PDS), through the 24-h HRV. We enrolled 14 patients with PDS (mean age: 84.5+/-6.9 years), they were compared to 13 frail control subjects (mean age: 80.6+/-6.7 years). Cardiac ANS activity was assessed by 24-h ECG recordings from three leads with a Holter digital monitor. The decrease in cardiac ANS activity observed in PDS subjects was greater than the alteration found in normally aging subjects. The abnormalities of ANS that aggravate the effects of aging can be seen as a type of physical deconditioning. Such patients could benefit from particular attention in physical training.

Aim: To determine the impact of taste pleasure supplements on modifications of food intake in hospitalized frail elderly patients., Methods: Thirty hospitalized frail elderly patients tasted different formulas of a high-protein coffee supplement: -supplement C, commercial version; - supplement CA with artificial coffee flavor; - supplement CS with sucrose and - supplement CAS with sucrose and artificial coffee flavor. The preference for the supplements was analyzed by the Friedman test followed by a post hoc Tukey's test. The food intakes in each period were compared by repeated ANOVA and the food intakes of the two periods were compared using Student's t test. All measurements were made during periods of infection and convalescence., Results: The supplements CAS and CS were significantly more appreciated than the current commercial version C (P < .05). The patients could be classified into two groups: consumers (consuming the supplements) and nonconsumers (just tasting the supplements). Taking supplements can increase the total energy intake for consumers (P < .01), especially during periods of infection; no modification was observed in the non-consumers., Conclusion: The use of supplements to increase sensory pleasure can be one feasible way to increase energy intake in hospitalized elderly patients with an infectious disease.

Objectives: The aim of this paper was to describe gait disorders and their consequences in primary dementias, and to prove the positive impact of their prevention and rehabilitation., Method: The most relevant articles on gait and dementias available on Medline were analyzed., Results: The prevalence of gait and balance disorders is between 9 and 52% in Alzheimer-type dementia in which frontal gait and apraxic gait are described. Gait disorders, appearing with a prevalence of over 71% in vascular dementia, seem to be an early indicator of this dementia in which hemiparetic gait, frontal gait and unsteady gait are commonly described. As clinical practice shows, gait disorders appear to be frequent in dementia with Lewy bodies and Parkinson's dementia, both being characterized by Parkinsonian gait; however, there are very few prevalence studies concerning gait disturbances in these two dementias. The balance and gait assessment in demented subjects is based on the analysis of sit-to-stand/back-to-sit and one-leg balance, the measurement of gait speed, the Timed-Up-and-Go and the dual task tests. Although there are few studies on the topic, the benefit of the motor rehabilitation on functional independency in demented subjects is now recognized. The programs used for motor rehabilitation of demented people must be individual with targeted objectives, and associate strength and balance exercises, attentional tasks, immediate and working memories and praxis, in the context of multidisciplinary intervention. However, there is no consensus on a standard rehabilitation program of demented subjects., Conclusion: Future studies have to analyse gait disorders in demented subjects in order to clarify their pathophysiology. Besides, they may confirm the benefit of rehabilitation and suggest consensual programs.

Stroke in the elderly has more major differences compared to young people: it is the first complication of atherothrombosis disease associated with the following risk factors: hypertension, diabetes, hypercholesterolemia, tobacco consumption and sleep apnea syndrome; AVC is the first consequence of atrial fibrillation; from a clinical point of view, seizure at the onset of the stroke is more frequent; prognosis is characterized by a high risk of dementia (20%); primary and secondary prevention is very efficacious even in very old patients, not only on the risk of stroke, but also on the risk of dementia; time trends at Dijon show a slight decrease of incidence rates of stroke only over 85 years, while prevention of stroke has taken advantage of real progress in precocious diagnosis and innovative treatments. In contrast, we observed a decrease of case-fatality rates at any day with a delay in age of onset of stroke, reaching five years in men and eight years in women, suggesting an increase of life expectancy without stroke, reflecting a certain efficacy of prevention.

In addition to the usual adverse effects, the chronic use of the valproic acid can entail dementia syndrome. We describe the case of a 68-year-old woman who had presented a dementia syndrome due to the use of valproic acid for one year. This drug was prescribed in order to prevent a potential convulsive crisis after an ischemic stroke in a patient who did not have a history of epilepsy. This case shows that each clinician must be careful about all medications consumed by the patient in the face of cognitive disorders.

We assessed the role of clinical and biological parameters on performance in four balance tests in elderly subjects. An observational study was conducted in the Center for Preventive Medicine of Nancy (France) in 2368 community-living elderly subjects aged 60 and older. Body mass index (BMI), Mini-Mental State Examination (MMSE), clock test, "Health score" and use of psychotropic drugs (UPD) were assessed. Participants performed four balance tests: "one-leg-stand" (OLS), "timed-up-and-go" (TUG), "rise-from-the-floor" (RFF) and "sit-to-stand" (STS). The statistical analysis showed that women were almost twice as likely to fail balance tests as men. In both women and men, the following determinant factors of the performance in balance tests were found: for OLS: age, BMI and health score; for TUG: age, BMI, clock test and health score; for RFF: BMI and health score. In addition, in women other determinant factors were: MMSE for OLS, UPD for TUG, age and clock test for RFF. In men, the clock test and the UPD were also significant determinant factors for OLS. Similar results were found for STS. In conclusion, female sex, overweight, low cognitive status, low self-perception of health and UPD were associated with a higher risk of failure in balance tests.

Background: There is currently a lack of consensus for the diagnosis, investigations and treatments of acute bacterial prostatitis (AP)., Methods: The symptoms, investigations and treatments of 371 inpatients diagnosed with AP were analyzed through a retrospective study conducted in four departments - Urology (U), Infectious Diseases (ID), Internal Medicine (IM), Geriatrics (G) - of two French university hospitals., Results: The cause of admission, symptoms, investigations and treatments depended markedly on the department of admission but not on the hospital. In U, patients commonly presented with a bladder outlet obstruction, they had a large imaging and functional check-up, and received alpha-blockers and anti-inflammatory drugs. In ID, patients were febrile and received longer and more appropriate antibiotic treatments. In G, patients presented with cognitive disorders and commonly had post-void urine volume measurements. In IM, patients presented with a wide range of symptoms, and had very diverse investigations and antibiotic regimen.Overall, a 3:1 ratio of community-acquired AP (CA-AP) to nosocomial AP (N-AP) was observed. Urine culture isolated mainly E. coli (58% of AP, 68% of CA-AP), with venereal agents constituting less than 1%. The probabilistic antibiotic treatments were similar for N-AP and CA-AP (58% bi-therapy; 63% fluoroquinolone-based regimen). For N-AP, these treatments were more likely to be inadequate (42% vs. 8%, p < 0.001) and had a higher rate of bacteriological failure (48% vs. 19%, p < 0.001). Clinical failure at follow-up was more common than bacteriological failure (75% versus 24%, p < 0.001). Patients older than 49 had more underlying urinary tract disorders and a higher rate of clinical failure (30% versus 10%, p < 0.0001)., Conclusion: This study highlights the difficulties encountered on a daily basis by the physicians regarding the diagnosis and management of acute prostatitis.

Backward disequilibrium is observed frequently in daily clinical practice. However, there are no epidemiological data concerning this postural disorder. Defined by a posterior position of the centre of mass with respect to the base of support, backward disequilibrium is abnormal postural behavior, usually characterized by a posterior trunk tilt in standing and sitting positions, which predisposes subjects to backward falls. Many afflictions whether they are somatic (degenerative, ischemic and traumatic brain lesions), psychosomatic (psychomotor disadaptation syndrome, confinement to bed, nonuse situations) or psychological (depression) can cause backward disequilibrium. A vicious circle of falls, and loss of autonomy can arise and this is the main consequence of backward disequilibrium. Thus, in this paper, we review backward disequilibrium in elderly subjects with regard to the causes, consequences, assessment, and management.

Objective: Deep-vein thrombosis is common but not easy to diagnose. It is generally considered that the diagnosis can be ruled out in subjects with a D-Dimer level lower than a reference threshold value. We report a case where this hypothesis was misleading., Method: An 89-year-old man was hospitalized for a pain in his left lower leg, which had been persistent for 5 days., Results: The venous duplex ultrasound found two recent deep-vein thrombi in this leg while the D-Dimer level was lower than 220 UI/ml at admission., Conclusion: This case illustrates the importance of prudent interpretation of the serum D-Dimer level.

Ionized calcium (Ca(2+)) seems to be the best measure of active serum calcium but, in France, numerous laboratories do not have Ca(2+) analyzers so that numerous clinicians use Payne's formula to obtain adjusted calcium (Ca(Ad)) values. In frail very elderly patients with protein/energetic malnutrition and very low concentrations of albumin, "correction" with Payne's formula usually gives false hypercalcemic results, so that hypocalcemia may be seriously underdiagnosed. Two hundred and ninety-four patients of 80 years and older with serum albumin level < 35 g/l were included in four French hospitals for elderly people. Biological measurements were standardized in order to determine Ca(2+) and total calcium (Ca(T)) in accordance with approved guidelines. Ca(Ad) was calculated with Payne's formula whereas the dependence of Ca(2+) with serum protein, albumin and Ca(Ad) was investigated by linear regression, the goodness-of-fit of each equation with the measure of Ca(2+) being studied. Taking into account serum protein and albumin levels, multiple linear regression gave the equation: Ca(2+) (mmol/l)=0.188-0.00469 protein (g/l)+0.0110 albumin (g/l)+0.401 Ca(Ad) with r(2)=0.442. The relative difference between the measure and the value given by the equation did not depend upon the center, and the correlation between measured and computed values of Ca(2+) was better, for any group, with our formula than with Payne's formula. When Ca(2+) was expressed with Ca(T) instead of Ca(Ad), albumin term was no longer significant and the new equation was: Ca(2+) (mmol/l)=0.592-0.00449 protein (g/l)+0.410 total calcium (mmol/l) with r(2)=0.438. We propose an alternative to direct measurement of Ca(2+) with a simple formula usable in geriatric units, which are often deprived of high-performance equipment.

Purpose: Although there is currently no epidemiological data on backward disequilibrium, this disturbance of posture does not seem to be rare in frail elderly., Actualities and Strong Points: Backward disequilibrium is characterized by the following criteria: the location of buttocks on the anterior side of the seat while the trunk rested at the back of the armchair in the sitting position; an inadequate forward of the trunk and a backward projection of the trunk outside the base of support during sit-to-stand; and a posterior projection of the center of mass outside the base of support in the standing position. Several pathological situations either somatic (degenerative, ischemic and traumatic brain lesions), psycho-somatic (psychomotor disadaptation syndrome, extended bed confining, non-use) or psychological (depression) affections can entail backward disequilibrium. Falls, loss of autonomy and the risk of the vicious circle with its causes are the main consequences of backward disequilibrium., Prospects and Projects: Although the geriatrician is familiarized with backward disequilibrium, there is no scale to quantify it. In this paper we review causes, consequences and management of backward disequilibrium, and in order to assess it, we propose a semi-quantitative scale, based on some activities of everyday living which are sitting position, sit-to-stand, back-to-sit and standing position. So, a backward disequilibrium score could be determined.

Objective: We hypothesised that backward disequilibrium (BD), defined by a posterior position of the centre of mass with respect to the base of support, could be caused by a backward tilt in the perception of verticality., Methods: The relationship between BD, the perception of verticality, and the history of falls in 25 subjects aged 84.5+/-7.4 years was analysed. An original ordinal scale, the BD scale (BDS), was used to quantify BD. Postural (PV) and haptic verticals (HV) were measured in sagittal plane., Results: BDS scores closely correlated with the number of falls (r = 0.81, p =10(-5)). The more the PV was tilted backward, the greater the BDS scores (r = -0.95, p<10(-6)), with a huge backward tilt of about 15 degrees in 4 subjects with severe BD. In these subjects, the tilt in perception of verticality was transmodal since a severe backward HV tilt was also found., Conclusions: This transmodality suggested high-order cognitive disruption in the construction of the subjective vertical used in postural control by subjects showing BD, which confirmed our hypothesis., Significance: This study clearly shows that perception and action with respect to gravity are closely related and brings a new insight about fall mechanisms in the elderly.

Purpose: We describe the psychomotor disadaptation syndrome and report the last findings on its physiopathology and therapeutic. This syndrome was first described by Pr Gaudet's team in 1986 and named "psychomotor regression syndrome". This name has been recently changed into "psychomotor disadaptation syndrome"., Actualities and Strong Points: The psychomotor disadaptation syndrome is a decompensation of postural function, gait and psychomotor automatisms due to the alteration of the posture and motor programming. That alteration is linked to subcortical-frontal lesions. Clinically, the psychomotor disadaptation syndrome is characterized by postural impairments (retro-propulsion or backward disequilibrium), non-specific gait disorders, neurological signs (akinesia, reactional hypertonia, alteration of both reactive postural responses and protective reactions) and psychological troubles. Psychological troubles include fear of standing and gait in its acute feature or slowness of cognitive processing and anhedonia in its chronic feature. The psychomotor disadaptation syndrome occurs as a failure to compensate for the effects of the following three factors which entail the reduction of motor functional reserves because of their impact on frontal subcortex: 1) aging, 2) chronic illness named predisposing factors (degenerative or vascular disorders) and both 3) functional and organic acute factors. The latter factors cause a reduction of cerebral blood perfusion. The psychomotor disadaptation syndrome requires multidisciplinary management including medical, physiotherapeutic and psychological approaches., Prospects and Projects: In the next years we have to determine the frequency of psychomotor disadaptation syndrome and its physiopathology needs to be further explored.

We determined whether management including medical, psychological, and physiotherapeutic approaches, over a period of 6 weeks, has a beneficial effect on motor abilities, psychological status, and independence of elderly fallers with psychomotor disadaptation syndrome (PDS). We included 28 subjects (mean age 81.4 years). They were assessed from a medical, motor, and psychological point of view at both the inclusion and the end of the multidisciplinary intervention. A follow-up was conducted with multidisciplinary assessment at 6 and 9 months after the beginning of the study in order to evaluate duration of benefits of the management. The statistical analysis concerned only subjects who took part in the total multidisciplinary program, i.e., 14 subjects. The multidisciplinary intervention had an overall positive impact on motor abilities as shown by the increase in the mini-motor test scores, the rate of success in rising from the floor and decrease of time for the dual task. This study also showed a reduction in the fear of falling and a decrease in the rate of fallers. This positive effect on motor abilities, fear of falling and rate of fallers was sustained until 9 months after the beginning of the multidisciplinary management. This study shows the importance of a multidisciplinary management of elderly fallers with PDS.

Following a report by the Health Ministry recommending a greater implication of general practitioners (GP) in the diagnosis and care of mistreated older people, we wanted to evaluate what was actually their role in this matter. A study was made of files of mistreated older persons referred to the social services in a Parisian suburb. For each file, we noted who raised the first suspicions of mistreatment, who diagnosed it, what happened next, and what precisely the GP's role was. Out of 600 files, we found 12 cases, concerning 14 persons (two couples). Although all the patients had health problems requiring frequent consultations with their GP, none of these situations were diagnosed by the GP. In all cases, the GP played only a secondary role, if at all. The following points are discussed: The link between family problems and history cannot be ignored in the follow up of such situations. The GP's role is discussed regarding clinical knowledge of mistreatment and the legal rules they have to deal with. Our results bring to light how the balance between the person's autonomy and the necessary direct action is especially delicate in this field.

The aims of this study were to analyze the effects of cognitive task on static posture in Alzheimer's disease (AD) and in healthy elderly (HE) subjects and to evaluate whether those effects were greater in AD subjects than in HE subjects. We performed a posturographic analysis on 13 subjects with mild AD (mean age, 79.7+/-5.1 years, Mini-Mental State Examination scores between 18 and 23) and on 17 HE subjects (mean age, 78.5+/-4.4 years). After watching a video sequence, the subjects were asked to maintain a stable upright posture while standing on a force platform. Then, the postural sway was measured during the following two conditions: (1) quiet standing and (2) both standing and answering questions about the video sequence. We were interested in the center of pressure (CoP) area and path. For each group, the single task was compared to the dual task for the CoP area and path. We also compared the variability of both CoP area (variation of the CoP area between the single and the dual task) and path (variation of the CoP path between the single and the dual task) between the two groups. We showed that there was no significant difference between the single and the dual task in HE subjects concerning the CoP area and path, in contrast to the AD group, and that variability of both the CoP area and path were significantly greater in the AD subjects than in the HE subjects. This finding may contribute to the risk of falls in AD patients., (Copyright (c) 2005 Movement Disorder Society.)

We studied the kinematics of shoulder displacement during sit-to-stand and back-to-sit in 6 healthy elderly subjects and six elderly subjects with mild to moderate Alzheimer's disease in order to elucidate the impact of Alzheimer's disease on motor planning and control processes. During sit-to-stand, Alzheimer's disease subjects reduced their forward displacement and started their upward displacement earlier than healthy elderly subjects. Furthermore, shoulder path curvatures were more pronounced for upward compared with downward displacement in healthy elderly group, in contrast with Alzheimer's disease group. Temporal analysis found that: 1) for both groups, profiles of velocity of sit-to-stand and back-to-sit showed two peaks corresponding respectively to forward/upward and to downward/backward displacements, 2) peaks of velocity were almost comparable between the two groups, 3) duration of sit-to-stand was shorter than duration of back-to-sit in the two groups and 4) duration of sit-to-stand and back-to-sit was shorter in Alzheimer's disease group than in healthy elderly group. However, dissimilarities were observed for transition and deceleration phases during sit-to-stand, and for acceleration and transition phases during back-to-sit, between the two groups. Interestingly, while sit-to-stand and back-to-sit differed in healthy elderly subjects during transition and deceleration phases, such a difference was not observed for Alzheimer's disease subjects. So, our study showed that invariant spatio-temporal movement parameters in the two groups differed, while non-invariant parameters did not, and suggests that higher level motor process of whole body motions are affected by Alzheimer's disease, while lower level motor features remain intact.

Background: Acute myocardial infarction (AMI) in elderly patients is often unrecognized and associated with poor prognosis., Objectives: To investigate management and efficacy of reperfusion therapy to the elderly patients with AMI., Methods: From the January 1, 2001 to October 31, 2002, 964 patients with AMI were included in the French regional RICO survey. The patients were divided into three groups: younger (<70 years old), elderly (70-79 years old) and very elderly (>or=80 years old)., Results: Distribution of groups was 56, 27, and 16%, respectively. The longest time delay to first request for medical attention was found in the very elderly group (30 and 55 vs. 90 min, respectively, p < 0.05). Rate of lysis fell significantly with increasing age (35, 22 and 9%, respectively, p < 0.001) but the time delay to lysis was similar for the 3 groups. The proportion of patients who benefited from primary percutaneaous transluminal coronary angioplasty decreased with age (21, 15, 11%, respectively, p < 0.001), but time delay to balloon angioplasty was similar and no difference in mortality rate was observed between the three groups after reperfusion. The incidence of in-hospital cardiovascular events (cardiogenic shock and recurrent myocardial infarction/ischemia) and in-hospital mortality increased with age (5, 13, 17%, respectively, p < 0.001). Moreover, multivariate analysis showed that only ejection fraction and Killip >1 were independent predictive factors for in-hospital cardiovascular mortality, respectively (OR 5.15, 95% CI 2.08-12.74, p < 0.0001 and OR 3.81, 95% CI 1.90-7.65, p < 0.0001), whereas age, sex, diabetes and anterior location were not significant., Conclusion: Our data in an unselected population indicate that very elderly patients were characterized by increased pre-hospital delays and less frequent utilization of reperfusion therapy, although no difference in the mortality in reperfused patients could be observed between the three age groups., ((c) 2005 S.

Introduction: Owing to the very great age and the polypathology of the patients in geriatrics, we are often confronted to the palliative care decision., Purpose: The purposes of this retrospective study were both to define the criteria leading to palliative care and to analyse the evolution of patients., Method: We analysed 40 files of patients hospitalised in Geriatric internal medicine or Geriatric rehabilitation departments over 11 months., Results: Mean age was 85.4 years and 62.5% of patients were females. Infections, heart failure, general weakness, orthopaedic affections, strokes and cancers were the main causes of hospitalisation. Patients had 3 medical or surgical histories of chronic or cured serious diseases and a MMSE average value of 17.7. The rate of malnutrition was 92% and 90% of patients were very dependent. Severe infections, cancers, heart failure and severe pressure ulcers were the main affections for decision of palliative care. The latter was always decided by the staff with patients or families taking part in 8 cases and being informed in other cases. The palliative care lasted 7 days on average. Morphine was used in 31 cases. No artificial nutrition was introduced., Conclusion: The decision of palliative care is very complex since great age, polypathology, great dependence and high prevalence of cognitive disorders are frequent in this population.

Stroke in the elderly differs from stroke in younger adults in several points. It represents the most frequent consequence of atherothrombotic disease associated with hypertension, diabetes and hypercholesterolemia. It is also the main complication of cardiac arrhythmia. From a clinical point of view, epileptic seizure is frequently observed at the onset, and prognosis is darkened by a high risk of dementia occurrence (20%). Management of stroke in acute phase requires intensive care, which has been shown to decrease mortality and handicap by 20% in Stroke Units. Fibrinolysis with rt-PA can be carried out till 80 years. Primary and secondary prevention are still very efficacious in old patients and decrease not only the risk of stroke, but also the risk of dementia. Moreover, influenzae vaccination has been shown to decrease the risk of stroke in the following year in subjects over 65 years.

Objective: To analyse the clinical usefulness and metrological properties of the main techniques and indices used to assess balance disorders., Methods: More than 4000 abstracts referenced in MEDLINE and dealing with postural control and postural disorders (wide screening) were reviewed to determine the main postural techniques and indices used in a clinical context. We retained abstracts with a high citation frequency and those with interesting findings. Corresponding key words were identified for a specific search of articles that we analysed., Results: Postural assessment tools can be classified as scales of ordinal items, tests based on metric or chronometric measurement, posturography, and verticality perception. These techniques are complementary, and their association is recommended in a clinical context. Regarding generic tools, the Falls-related Efficacy Scale (FES) and the Activities-specific Balance Confidence scale (ABC scale) would be enhanced if comparatively analysed and reworked to allow for a feasible and reliable assessment of the fear of falling. Despite a wide diffusion in numerous postural fields worldwide, the Berg Balance Scale (BBS) and the Functional Reach Test (FRT) do not have the required criteria to remain the gold standards they were in the 1990s. Static posturography should be normalised and yield more reliable indices. The clinical relevance of the subjective assessment of visual, haptic, and postural verticals are questionable, especially to explain postural disability. Regarding specific tools, the Tinetti test (TT) and the Time Up and Go test (TUG) are the most suited to assess postural capacities in very elderly people, in whom the predictive validity of the postural assessment of falls is still modest. In stroke patients, the Postural Assessment Scale for Stroke (PASS), posturography, lateropulsion assessment, and vertically perception are interesting and complementary techniques. Postural assessment relies mainly upon the 5 postural items of the Unified Parkinson Disease Rating Scale (UPDRS) in people with Parkinson disease and upon the Romberg test and posturography in patients with cerebellar or proprioceptive ataxia. Some novel postural scales for patients with multiple sclerosis or spinal cord injury are also emerging., Conclusion: Among numerous tools that contribute to the assessment of postural disorders, only the most recent ones (developed in the last 10 years) have undergone complete validation. It is now crucial to compare these tools, not only in terms of reproducibility and internal consistency, but also overall, in terms of feasibility, responsiveness, and predictive validity for a given population.

Purpose: Fifty percents of cancer arise in people older than 65-year-old. Most clinical trials in cancer treatment are limited in patients younger than 65-year-old. We review literature-describing particularity of cancer treatment in elderly patients., Current Knowledge and Key Points: Therapeutic decisions should be based on an estimation of the patient's life expectancy, and risks and benefits should be weighted up accordingly. Geriatric oncology is made of a geriatric evaluation of patient and of knowledge of clinical trial about elderly patients., Future Prospects and Projects: We present in this issue the principle of geriatric evaluation and the results of recent clinical trial on elderly cancer patients.

Direct observation of postural and motor abilities appears as very important in assessment of patients showing psychomotor disadaptation syndrome (PDS). We examine feasibility and reliability of mini motor test (MMT) which has been developed in order to establish rehabilitation goals in this population. MMT is a 20-item score which assesses abilities in bed, quality of sitting position, abilities in the standing position, and quality of gait. MMT has been conducted by two different independent investigators, a physiotherapist and a physician, in four different geriatric centers. One hundred and one subjects (mean age: 84.9 +/- 6.0 years) were included in the study. The agreement between the two investigators was highly satisfying for both MMT total score and each item of MMT. Redundancy between items appeared very limited. The difference between investigators for MMT total score did not vary significantly with score of the mini-mental-state examination (MMSE). The correlation between MMT and the Katz index was found significantly negative. MMT is an easy direct-observation test which may be particularly useful in patients who present with severe postural and gait impairment. This test can be used in clinical practice by different professional actors in order to allow an interdisciplinary approach for a common rehabilitation goal in the PDS patients.

Background: This study investigated the hypothesis that postural abnormalities might increase energy expenditure during a clinical functional test in frail elderly persons., Methods: Two groups of hospitalized women (aged 73 to 100 years) were recruited. Women who showed postural and gait abnormalities as described in the psychomotor disadaptation syndrome (PDS) were compared with control participants. The authors measured energy expenditure during the timed "up and go" test. For each participant, oxygen uptake, carbon dioxide output, expiratory minute ventilation, breathing frequency, heart rate, and alveolar ventilation were recorded 10 minutes before, during, and 10 minutes after exercise. The arterial pressure of carbon dioxide was estimated from expired gases., Results: The mean oxygen uptake values were significantly higher in women with PDS than in the control group during exercise and recovery periods (4.89 +/- 1.68 vs 3.75 +/- 1.25 ml . kg(-1) . min(-1) and 4.69 +/- 1.45 vs 3.76 +/- 0.97 ml . kg(-1) . min(-1), respectively [p <.05]). Expiratory minute ventilation was always higher in women with PDS than in controls regardless of the period of the test (p <.05), and alveolar ventilation was higher in women with PDS only during the exercise period (p <.05). The estimated arterial pressure of carbon dioxide did not change significantly between the different phases of the test but was always lower (p <.05) in women with PDS compared with the control group., Conclusions: The significant increase in oxygen uptake during the exercise and recovery periods in women with PDS compared with controls suggests that postural abnormalities that characterize PDS may be associated with an increase in energy expenditure. In clinical practice, the low capacity to tolerate even moderate exercise must be considered when specific rehabilitation programs are offered to women with PDS.

Background: Frontal-subcortical clinical syndrome (FSCS) is frequently described in elderly patients and consists of specific alterations in cognition and motor functions. This clinical picture may be associated with a high level of dependence and a high mortality risk., Objective: We report the risks of institutionalization and death during a follow-up of 4 years in patients showing FSCS., Methods: The study was initiated in 1998 to compare FSCS patients showing postural and gait abnormalities with Alzheimer's disease (AD) patients. Follow-up was conducted by means of telephone interviews with the patient's general practitioner over a 4-year period (1998-2002)., Results: Both institutionalization and mortality rates were significantly higher (p < 0.05) in the FSCS group compared to the AD group., Conclusions: The high risk of disability and death in FSCS patients suggests that they might require specific care programs that include stimulation in daily living activities in order to reduce the risk of institutionalization and to improve quality of life., (Copyright (c) 2005 S.
