[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.

[Dementia and falls].

INTRODUCTION: Dementia is now a frequent disease in elderly and may be a major risk of falling. Usually these falls are multiple and serious, but their consequences are not specific. All types of dementia (Alzheimer's disease, dementia with Lewy bodies, dementia in Parkinson's disease, fronto-temporal dementia, vascular dementiaellipsis) and all stages of evolution are concerned. DISCUSSION: These falls result from cognitive and behavioural disorders, visual and motor problems, gait and balance disturbances, malnutrition, adverse effects of medication and fear of falling. CONCLUSION: Prevention is possible. Attention must be given on the patient himself (keeping in good health, limitation in sedative treatment and mechanical restraintsellipsis) and on his environment (lighting, obstacles on the ground, stress levelellipsis). After a fall, especially after a complicated fall, rehabilitation modalities and aims must be adapted but caring must not be defeatist. Randomized studies need to be realized.

[Extra-pyramidal syndrome induced by donepezil].

BACKGROUND: The cholinergic hypothesis of Alzheimer's disease is the basis of a new class of drugs: acetylcholinesterase inhibitors. These drugs have few side effects, mainly digestive disorders. CASE REPORTS: Extra-pyramidal side effects with severe gait disorders were observed in 3 patients with Alzheimer's dementia treated with donepezil. This drug was associated with paroxetine or a neuroleptic. In 2 of the 3 cases, the extra-pyramidal effects disappeared when donepezil was discontinued. DISCUSSION: Extra-pyramidal syndromes in elderly subjects with cognitive impairment are difficult to interpret. The possible causes include interactions between acetylcholinesterase inhibitors, neuroleptics and serotonine reuptake inhibitors and Lewy body dementia.

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.

Subacute bacterial endocarditis presenting as polymyalgia rheumatica or giant cell arteritis.

OBJECTIVE: To report on several patients with subacute bacterial endocarditis who were initially presumed, incorrectly, to have polymyalgia rheumatica or giant cell arteritis. METHODS: We report 3 cases of subacute streptococcal endocarditis mimicking giant cell arteritis in 2 cases and polymyalgia rheumatica in one. We reviewed the literature through Medline search of French and English-language articles published between 1966 and 2005 and found 5 similar cases. RESULTS: Shoulder and/or pelvic girdle pain was associated with neck or back pain in all patients. Scalp tenderness, bilateral jaw pain, amaurosis fugax were present in 2 patients. One patient had no fever. Two patients were treated with corticosteroids with initial good clinical response in one. Appropriate antibiotic therapy resulted in the rapid disappearance of rheumatic complaints in 2 patients and achieved a definitive cure of endocarditis in all cases. CONCLUSION: Rheumatologic symptoms may hinder the correct diagnosis of infective endocarditis in patients who present with a clinical picture suggesting polymyalgia rheumatica or giant cell arteritis. In such cases, blood cultures should be systematically drawn.
