[Microbial description of bacteriuria in long-term care facilities: a prospective study in the French Teaching Hospital of Strasbourg].

OBJECTIVE: The authors had for aim to assess, the incidence of symptomatic bacteriuria and the level of antibiotic resistance in bacteria identified in long-term care facilities (LTC). DESIGN: Symptomatic bacteriuria cases were prospectively collected, during 9 months in the two LTC of the Strasbourg French Teaching Hospital (196 beds). RESULTS: One hundred and eleven bacteriuria cases were included. They concerned 67 of the 274 residents (cumulative incidence: 2.07/1,000 patients-day). A gram-negative bacillus was identified in 85% of the symptomatic bacteriuria cases, and Escherichia coli in 40%. Sixty percent of the identified bacterial strain was resistant to amoxicillin (Amx-R) and 42% to the clavulanic acid combination (AmC-R). Third generation cephalosporins (3GC) were effective in 90% of Urinary tract infections (UTIs) and fluoroquinolones in 65% (Fq). Four bacterias with broad beta-lactamase spectrum were identified (0.04%) including 3 Enterobacter aerogenes. No yeast infection was diagnosed. E. coli strains were 65% Amx-R and 50% AmC-R. Concerning the Fq-R strains (15%), 50% were cotrimoxazole resistant (Stx-R) and 70% Amx-R; 3GC remained effective (82%). CONCLUSION: In LTC, multi-drug resistance bacteria are rare and 3GCs seem to be the best first line treatment. Nevertheless, Fq-R is increasing (15 vs 8%), and attention must be paid to the antibiotic therapy used.

[Consensus statement on severe dementia].

Under the auspices of the French Society of Gerontology and Geriatrics, a multidisciplinary group of experts, including geriatricians, neurologists, epidemiologists, psychiatrists, pharmacologists, and public health specialists developed consensus recommendations about care for patients with severe dementia. They defined 21 recommendations for general practitioners, long-term care physicians, and specialists, based on the knowledge currently available (2005). The aim of care at all stages is to mitigate the quality-of-life of patient, caregiver, and family insofar as possible, combining care and future planning until the end of life. Management, to take into account problems including nutritional status, behavior disorders, and ability (or inability) to perform activities of daily living, must be global, multidisciplinary, and coordinated and must optimize use of local medical and social resources. The group also stressed the importance of clinical research to improve knowledge of disease course and assess management strategies and recommended specific area for research.

[Low vitamin B12 levels in elderly patients cured within one week by oral cobalamin therapy].

OBJECTIVE: Non-dissociation of vitamin B12 from its carrying proteins is the most frequent cause of vitamin B12 deficiency in the elderly. The aim of this study was to determine the initial dose of oral cyanocobalamin that would correct the B12 vitamin deficiency within one week. METHODS: This was an open, prospective, study on 30 elderly patients suffering from vitamin deficiency (B12 < 0.20 microg/L) induced by food-cobalamin malabsorption. Ten patients (group I) were treated with a daily dose of 1000 microg of oral cyanocobalamin (from D1 to D8), 10 (group II) with 1000 microg every other day (D1, D3, D5 and D7), 5 (group III) with 1000 microg every 4 days (D1 and D5) and 5 (group IV) with 1000 microg only on D1. The biological response was assessed by control measurement of vitamin B12 serum levels on the 8th day. RESULTS: Mean vitamin B12 serum levels had significantly increased (p < 0.01) in groups I, II and III, but not in group IV. The dose-effect, assessed by the mean increase in vitamin B12 serum levels, was significantly greater (p < 0.05) in groups I (0.25 microg/L) and II (0.18 microg/L), than in groups III and IV (0.09 microg/L). CONCLUSION: This prospective study shows that an oral dose of 1000 microg of cyanocobalamin every 4 days, which corresponds to 250 microg per day, was sufficient to correct B12 vitamin deficiency induced by food-cobalamin malabsorption within one week. However, initial doses of 1000 microg per day or every other day would be preferable because of the greater dose-effect with daily doses higher than 500 microg. A randomised study is warranted to validate these preliminary results.

[Consensus statement on severe dementia].

Under the auspices of the French Society of Gerontology and Geriatrics, a multidisciplinary team including geriatritians, neurologists, epidemiologists, psychiatrists, pharmacologists and public health specialists developed a consensus on care for patients with severe dementia. They defined 21 recommendations for general practitioners, long-term care physicians and specialists based on knowledge available in 2005. At all stages of the disease, the objective of care is to improve as much as possible quality-of-life for the patient and his/her family, including a life project until the end of life. It is always possible to do something for these patients and their family: nutritional status, behavior disorders, and incapacities to deal with basic activities of daily life have to be taken in consideration. Resource allocation and proximity care have to be targeted. Research areas necessary to improve the care of patients with severe dementia has been selected.

[Home living conditions in Alsace of the disabled elderly aged 75 years and more].

OBJECTIVE: Our aim was to describe the living conditions of disabled elderly subjects aged 75 years and more living at home. DESIGN: This study was conducted in 1996-97 in the Alsace region in France and included two parts. First, a sample survey was mailed to 15,600 subjects randomly selected from a pension funds list. This survey provided with a reliable representation of the study population in terms of disabilities using the Colvez classification. In the second part, the most disabled individuals were selected and, among them, 1,259 subjects were visited at home. Their disabilities and living conditions were noted using a predefined set of questions. RESULTS: An estimated 71,000 subjects aged 75 years and more lived at home in the study region. The vast majority were free of significant disability. Help to wash and dress was needed by 6,000 until 1,500 were bedridden or confined to an armchair. Between 4,350 and 5,400 met the criteria for iso-resource grades (IRG) 1 to 3. Disability was associated with age, female gender, cognitive impairment and some social and professional characteristics. Family support was routine in almost every aspect of everyday life including personal hygiene. Professional support was mostly limited to technical interventions. Professional nursing care concerned only the most dependent persons. Nevertheless, needs for help in home and social activities remained high even in the least dependent individuals and were strongly age-dependent. Only 10% of individuals with IRG 1 to 3 complained of inadequate help. More than 80% of the elderly felt comfortable with their living conditions at home and were not thinking of moving from home to an institution for old people. CONCLUSION: The present study confirms the important commitment of family members and their close relationships toward their elderly.

Efficacy of short-term oral cobalamin therapy for the treatment of cobalamin deficiencies related to food-cobalamin malabsorption: a study of 30 patients.

BACKGROUND: It has been suggested that oral cobalamin (vitamin (B12)) therapy may be an effective therapy for treating cobalamin deficiencies related to food-cobalamin malabsorption. However, the duration of this treatment was not determined. PATIENTS AND METHOD: In an open-label, nonplacebo study, we studied 30 patients with established cobalamin deficiency related to food-cobalamin malabsorption, who received between 250 and 1000 microg of oral crystalline cyanocobalamin per day for at least 1 month. ENDPOINTS: Blood counts, serum cobalamin and homocysteine levels were determined at baseline and during the first month of treatment. RESULTS: During the first month of treatment, 87% of the patients normalized their serum cobalamin levels; 100% increased their serum cobalamin levels (mean increase, +167 pg/dl; P < 0.001 compared with baseline); 100% had evidence of medullary regeneration; 100% corrected their initial macrocytosis; and 54% corrected their anemia. All patients had increased hemoglobin levels (mean increase, +0.6 g/dl) and reticulocyte counts (mean increase, +35 x 10(6)/l) and decreased erythrocyte cell volume (mean decrease, 3 fl; all P < 0.05). CONCLUSION: Our findings suggest that crystalline cyanocobalamin, 250-1000 microg/day, given orally for 1 month, may be an effective treatment for cobalamin deficiencies not related to pernicious anemia.

[Urinary tract infections due to wide spectrum beta lactamase producing enterobacteriaceae].

OBJECTIVES: The aim of this study was to specify the characteristics of enterobacterial urinary infections producing wide spectrum beta-lactamase (WSBL) and the management strategies for these patients infected in geriatric wards. METHODS: The prevalence, bacteriological characteristics and treatment regimens of enterobacterial urinary infections producing WSBL, diagnosed in a geriatric department of internal medicine from May 1977 to April 2001, were studied retrospectively. RESULTS: Sixty-six enterobacterial urinary infections producing WSBL were diagnosed, with 53 (80%) of them acquired in the ward. They represented 1.6% of admissions and concerned 24 men and 42 women (sex ratio: 0.57), with a mean age of 87 years. Their prevalence was of 20 in the 1st year, 11 in the 2nd, 9 in the third and 26 in the 4th year. The mean duration of hospitalization of infected patients was 4.5-fold longer (90 vs. 20 days) and the mortality rate 2-fold higher (32 vs. 14%). Enterobacter aerogenes were responsible for half (46%) of the WSBL urinary infections. The skin was invaded by enterobacteria in 67% and the feces in 57% of cases. More than one third of the urinary infections treated relapsed, and digestive decontamination was only efficient in half of the patients treated. CONCLUSION: This 4-year study emphasizes the limits of antibiotherapy in eradicating WSBL-producing enterobacteria and the fact that only the strict respect of hygiene by all caregivers (isolation of patients exhibiting WSBL and washing-disinfection of the hands between each patient) limits the incidence of such infections.

[Candidemia in elderly people: apropos of 4 cases].

INTRODUCTION: Candidemia, principally affecting neutropenic patients in departments of oncohematology and frail patients in intensive care units, can also be observed in frail elderly people in geriatrics. EXEGESIS: Authors report four observations of candidemia diagnosed in elderly dependent patients having several different diseases. Clinical sign was a persistent or recurrent fever after a wide-spectrum antibiotic therapy. Patients were treated by fluconazole leading to negative blood cultures in several days. Three out of four patients died within the weeks following antifungal therapy due to severity of associated diseases. CONCLUSION: These observations show that a diagnosis of candidemia should be made when a persistent fever is observed in a frail elderly person. Fluconazole, as efficient as amphotericin B and well tolerated by elderly people, should be the first treatment of candidemia in non-neutropenic patients.

[Influence of age on presentation and prognosis of tuberculosis in internal medicine].

OBJECTIVES: To compare the clinical, biochemical, radiological features and the outcome of elderly and young patients with tuberculosis. METHODS: Between 1980 and 1997, 83 patients diagnosed as having tuberculosis were treated in two departments of Internal Medicine and Geriatrics. They were divided into 42 young (< 65 years) and 41 elderly (> or = 65 years) patients and differences in presentation between the two groups were analysed. RESULTS: A past history of tuberculosis was found in 10% of young and in 18% of elderly patients (p = 0.43). Cancer was more often associated with tuberculosis in elderly patients (2% vs 15%, p = 0.09). The sites of disease were similar in both groups with 2/3 of pulmonary infection. Comparison of the presenting symptoms showed no significant difference for weight loss (52% vs 66%, p = 0.31), fever (52% vs 56%, p = 0.90) and cough (33% vs 32%, p = 1). The skin testing was positive for the majority of the young adults (84% vs 58%, p = 0.11). The commonly observed biochemical abnormalities in elderly patients were an increased erythrocyte sedimentation rate (49 vs 69 mm/h: p = 0.03) and lymphocytopenia (1724 vs 1059/microliter, p < 0.01). There was no significant difference in radiographic findings between both groups with miliary tuberculosis in about 10% of patients. During the first three months of treatment, the mortality was especially high (22%) for the elderly patients. CONCLUSIONS: Comparison of the clinical and radiological features of tuberculosis in internal medicine showed no significant difference in young and elderly patients.

Spontaneous insufficiency fractures of long bones: a prospective epidemiological survey in nursing home subjects.

A 30-month prospective observational cohort study was led to assess the prevalence of and describe the clinical features of spontaneous long bone insufficiency fractures (LBIF) in the 'oldest old' patients of long-term nursing homes (LTNH). The study was conducted in 30 LTNH in northeast France, which represented 3052 beds. Subjects aged 65 and more showing LBIF were included in the present study. Clinical data and outcome were collected. Fifty-five LBIF were found. The prevalence of LBIF calculated on the basis of the number of patients consecutively admitted in LTNH was 1%. The mean age of the subjects was 85+/-7 years. The LBIF sites were as follows (1) hip fractures in 15 subjects (27%); (2) femoral shaft fractures in 13 subjects (24%); (3) tibia and/or fibula fractures in 14 subjects (25%); (4) humerus fractures in 11 subjects (20%); (5) cubitus in 2 subjects. The global mortality at 2 months was 24%. The poorest outcome was observed in the group with femoral shaft fracture who showed mortality of 54% at 2 months. The dramatic repercussions in outcome and quality of life in bedridden patients show that the detection of LBIF should not be neglected in nursing homes. There is no consensus for a preventive pharmacological treatment in these patients. Educational programs for 'proper handling' by the nursing staff are highly recommended.

[Clinical and prognostic aspects of spontaneous fractures in long term care units: a thirty month prospective study. Eastern Gerontology Society].

PURPOSE: Spontaneous fractures (stress and bone insufficiency fractures) are well described in young healthy patients; however, few studies were conducted in the elderly. METHODS: A 30-month prospective clinical and epidemiological survey including elderly patients from long-term nursing homes (LTNH) of the Société de Gérontologie de l'Est (70 centers; 11,495 elderly patients in total) was conducted. RESULTS: Sixty-seven spontaneous fractures were encountered in 30 LTNH (3,052 elderly patients) (five stress fractures of the foot, 62 bone insufficiency fractures). The mean age of bedridden patients was 85 +/- 7 years. The prevalence of spontaneous fractures (calculated from the number of patients admitted consecutively in LTNHs) was 0.34% in the whole population (11,495 beds). When the calculation was based on LTNH reports of spontaneous fractures (3,052 elderly patients), the prevalence reached 1.3%. Fractures of long bones were common in elderly patients and included 15 fractures of the femoral neck, 14 fractures of either the tibia or fibula, 13 fractures of the femoral shaft, and 11 fractures of the humerus. Fractures of the femoral shaft were associated with the highest mortality: seven out of 13 patients died versus two out of 15 patients with regard to fractures of the femoral neck (P < 0.05). CONCLUSION: Bone insufficiency fractures have not the same course in young healthy patients as those in elderly nursing home patients: they more often concern long bones and their prognosis is worse. Means of prevention still have to be defined.

[Hospital discharge for elderly persons: a cross-sectional study in Alsace].

The objectives of this study are to analyse in the Alsacian region the needs of people aged 75 years old and over after a stay in hospital. It is also to identify the matching point between the ideal patient discharge and the one feasible in reality. Finally, if no matching point is found, the study examines the reasons for this. This is an exhaustive overview conducted 8th December 1994 in the 96 Alsacian hospitals on all patients aged 75 and over than 10 days in short stay services and over 20 days in medium stay services. Thus 965 questionnaires were analysed. On leaving hospital, 60% of ideal discharge are feasible. This percentage varies according to the kind of discharge. From 18% for the Alzheimer units it reaches 91% for "home stay without arrangement". When the ideal discharge is "long stay", it is often not feasible due to structural causes. On the contrary, when going home is the ideal solution, this is often not feasible due to lack of motivation either from the patient or their family.

[Surgical treatment of invalidating musculo-tendinous retractions in the dependent elderly].

The authors have reviewed 37 patients aged 64 to 91 years or their charts in the purpose to evaluate the results of surgical treatment of severe acquired contractures of arms hands and legs. They describe the deformations, surgical technique, morbidity, and the results. 4 patients deceased within the first week after surgery; morbidity was very low. The results were satisfactory: nursing was greatly facilitated and pain during nursing care and toilet disappeared, the patients could again seat in a wheel chair. They conclude that this surgery can be very helpful for these disabled patients.
