The influence of age on the prevalence of argyrophilic grain disease has been analyzed in the hippocampus from 29 centenarians. Argyrophilic grains were detected in 12 cases with Gallyas silver method, in 24 cases with anti-exon 10 (RD4) immunohistochemistry, in all the cases with a phospho-independent anti-tau (piTau) antibody and with a monoclonal antibody against Ser202 of the tau protein (AT8), suggesting a maturation of the grains. Ballooned neurons were found in the hippocampus of 12 cases in which grains were, on average, more abundant. Coiled bodies were found in 26, 15 and 13 cases respectively with piTau antibody, RD4 and Gallyas method. Cases with coiled bodies had a higher density of grains. The mean density of grains did not differ in the patients with or without dementia. The prevalence of tau-positive grains has been underestimated in the very old population. As neurofibrillary tangles, they appear to be a constant accompaniment of age but, contrarily to neurofibrillary tangles, do not seem to be strongly associated with dementia. © 2009 Elsevier Inc.

Even though digoxin causes many side effects, few cases of skin involvement are recorded in the French Pharmacovigilance Database. We report a case of leukocytoclastic vasculitis (LV) very probably due to digoxin. A 91-year-old woman, hospitalized following a fall, presented cardiac decompensation in a context of rapid atrial fibrillation requiring treatment with digoxin. Eight days later, a rash appeared on her back and trunk. It was neither itchy, nor painful and persisted despite local treatment. There were no other clinical anomalies. After a few days, the rash spread with appearance of bullous lesions, ulcerations and a necrosis on lymphedema of the two legs. Among the complementary examinations, skin biopsy revealed LV with necrosis and subepidermal detachment suggested toxic dermal necrolysis, while direct immunofluorescence was negative. The rash resolved progressively once the digoxin was stopped. The pharmacovigilance department recorded that digoxin was the probable cause. The evidence allowed us to conclude that digoxin was the cause.

Psychomotor disadaptation syndrome (PDS) was first described in France by the Dijon geriatric school, 25 years ago, and named "psychomotor regression syndrome". The initial clinical description still remains without modifications. However, progress has been made both in understanding its physiopathology and management, and its name has been changed into PDS in the late 1990s. Since the early 2000s, it was also termed frontal-sub-cortical dysfunction syndrome. PDS results from decompensation of postural function, gait and psychomotor automatisms linked to posture and motor programming impairment related to fronto-sub-cortical lesions. PDS is characterized by retropulsion, nonspecific gait disorders, neurological signs (including akinesia, reactional hypertonia, and impaired reactive postural responses and protective reactions) and psychological disorders (fear of standing and walking as an acute feature or cognitive processing retardation and anhedonia as a chronic feature). PDS occurrence is linked to three factors implicated in functional reserve impairment due to frontal-sub-cortical structures disturbances: aging, chronic affections (mainly of degenerative or vascular origin), and acute organic or functional factors which induce cerebral blood flowdecrease. Multidisciplinary management, including medical motor physiotherapy and psychological approach, is required for patients with PDS are.

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 40s. 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 (F1,16=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 (F1,18=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. © 2009 Elsevier Ireland Ltd.

Flu vaccinations for healthcare professionals seems to be one of the most effective preventive actions in the face of a disease that carries a high risk of a potentially serious nosocomial epidemic in a geriatric environment. The aim of this study was to take stock of the flu vaccination status among caregivers in the geriatric units and to understand the reasons for their reluctance to be vaccinated, in order to put forward proposals to improve vaccination coverage.A literature search of articles published since 2000 in the area of geriatrics, infectious diseases or pneumology was mainly conducted on PubMed using the keywords caregivers, elderly, flu, influenza, nosocomial and vaccination. After reading all abstracts in English or French and ruling out irrelevant articles, only 64 relevant articles have been listed in bibliography section.Despite official recommendations, the literature reveals insufficient vaccination coverage of healthcare personnel at both the national and international level. Vaccination coverage seems to be lower among younger female non-medical staff. The factors that determine the likelihood of vaccination are the wish to protect ones self, ones family and patients/residents, as well as the experience of earlier bouts of flu. Factors that oppose vaccination are complex and related to the fear of side effects, the use of other preventive measures, the feeling that vaccination is ineffective, poor understanding of the disease and the vaccine, forgetfulness and problems of organization. Campaigns to promote vaccination that target healthcare professionals must be multidimensional and very incentive. The pedagogical message must be centered on the benefits to the individual and adjusted to socio-professional categories. Mobile strategies in the different departments to encourage staff are a pragmatic solution to this challenge. The referring doctor has an essential role to play, as does the occupational doctor in association with the hospital hygiene services.Flu vaccinations must be included in the education and training of caregivers.

Neuroleptics may cause side effects, some of which are little known. We describe here a case of gastric dilation related to treatment with a neuroleptic in an elderly man. To our knowledge, such a case has never been reported in the literature. A 76-year-old man, living in a nursing home, was hospitalized for general weakness and abdominal pain. He had dementia with behavioral disorders treated with cyamemazine, a sedative and anxiolytic neuroleptic. Given a clinical suspicion of intestinal occlusion, an abdominopelvic computerized tomography scan was performed before the patient was admitted to our hospital. This computerized tomography scan did not show intestinal occlusion and there was no mention of gastric dilation in the computerized tomography scan report. Thus, acute gastroenteritis was suspected. The usual medications were stopped and symptomatic treatment for gastroenteritis was started. Quickly, his clinical state and biological parameters returned to normal and his usual treatment, including cyamemazine, was started again. The next day, the digestive symptoms, except for obstipation, reappeared. The abdominal X-ray showed gastric dilation without intestinal occlusion. The neuroleptic was stopped again and symptoms vanished the next day. This report underlines all of the necessary precautions and surveillance around drug prescription, especially in elderly persons.

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 Mutualit-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% -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.

Given the implications of rehospitalization at the individual and societal level, it seems important to identify elderly persons (EP) at risk. We analyzed the predictive factors of early rehospitalization in EP aged 75years or more hospitalized in a medicine department.A single-center retrospective study that included EP aged 75years or more hospitalized in a polyvalent medical department following an emergency admission. Patients who died during the hospitalization, who had been transferred or hospitalized during the previous month, were excluded. The impact of sociodemographic, administrative and biomedical data on rehospitalization at one month was analyzed.A total of 319hospitalizations were collected (mean age of patients: 84.75.7years). Most lived at home (80.2%) and among these 8.4% had no home help. The rehospitalization rate was 16.3%, among which 2/3were related to the reason for the initial hospitalization. Among the predictive factors found in the univariate analysis (male sex, multiple diseases, polypharmacy, multiple hospitalizations, cognitive disorders and calls to emergency services), only the presence of at least two previous hospitalizations in the year (odds ratio [OR]=2.10; 95% confidence interval [95%CI] [1.01-4.39]; P=0.048) and the presence of confusion without dementia (OR=3.78; IC 95% [1.09-13.06]; P=0.04) were significant. Discharge to a rehabilitation unit and increased support at home did not affect the likelihood of rehospitalization.The rehospitalization of EP is frequent and difficult to anticipate because there are few predictors and their impact is weak. The most important factors were medical: multiple hospitalizations and confusion without dementia.

Olfaction is a complex sensory system, and increasing interest is being shown in the link between olfaction and cognition, notably in the elderly. In this literature review, we revisit the specific neurophysiological features of the olfactory system and odorants that lead to a durable olfactory memory and an emotional memory, for which the implicit component produces subconscious olfactory conditioning. Olfaction is known to affect cognitive abilities and mood. We also consider the impairment of olfactory function due to ageing and to neurodegenerative diseases, in particular Alzheimers disease and Parkinsons disease, through anatomopathological changes in the peripheral and central olfactory structures. The high frequency of these olfactory disorders as well as their early occurrence in Alzheimer disease and Parkinson disease are in favour of their clinical detection in subjects suffering from these two neurodegenerative diseases. Finally, we analyse the impact of olfactory stimulation on cognitive performance and attention. Current observational data from studies in elderly patients with Alzheimer-type dementia are limited to multiple sensory stimulation methods, such as the Snoezelen method, and aromatherapy. These therapies have shown benefits for dementia-related mood and behaviour disorders in the short term, with few side effects. Since olfactory chemosensory stimulation may be beneficial, it may be proposed in patients with dementia, especially Alzheimer-type dementia, as a complementary or even alternative therapy to existing medical strategies.

For older adults, an Emergency Department (ED) visit represents a period of vulnerability that extends beyond the visit itself. This study aimed to determine the impact of the role of caregiver, and geriatric conditions of patients on early unplanned rehospitalization (EUR) within 3 months after an ED visit.This prospective longitudinal experimental study included consecutively 173 patients aged 75 and older admitted in an ED over a 2-week period (18.7% of the total visits). Only older patients having a caregiver were analyzed (78.0%, n = 135). Medical conditions and a comprehensive geriatric assessment were recorded for each patient. All caregivers were interviewed about their tasks and emotional impact using the short Zarit Burden Inventory. Three months after, patients or their caregivers were called about the vital status, and EUR of patients.Among the patients included, 64.2% had an EUR and 28.9% of their caregivers reported a high level of burden. EUR was strongly associated with a high caregiver burden (OR 8.7, 95% CI 1.5-49.8). No association was found for patients medical or geriatric status. Caregivers reported a significantly high burden when patients were malnourished, or were at risk of adverse health outcomes based on the ISAR scale, and when they had greater disabilities in IADLs and ADLs, or cognitive impairments.Many hospital readmissions after an ED visit may be preventable by identifying caregivers high burden. Reasons that lead to this high burden should be checked at the first visit.
