[Psychometric properties of the Euroqol measure in patients with muscular dystrophy].

OBJECTIVE: To analyse patient-reported outcome measures and to assess acceptability, test-retest reliability and responsiveness of the Euroqol measure (EQ), a conceptual health-related quality-of-life measure (HRQoL), for patients with muscular dystrophy. MATERIALS AND METHOD: One hundred and four consecutive outpatients completed the EQ in Reims university hospital between April 2002 and February 2005, and 60 patients were followed over 1 year. The acceptability of the EQ-5D and EQ-EVA measures was assessed by using the completion rate per dimension as an indicator; test-retest reliability was assessed with kappa and Spearman coefficients for qualitative data and the intraclass coefficient correlation (ICC) for quantitative data. Over the year, EQ-EVA score responsiveness was calculated according to the standardised response of the mean (SRM). RESULTS: Participation rate (96.3%) and EQ-5D completion rates were excellent, between 95.2 and 100%. Test-retest reliability after 15+/-7 days was excellent for the autonomy domain (kappa coefficient=0.81) and moderate for the other dimensions. EQ-EVA score stability was satisfactory (ICC=0.72). Global perceived health (EQ-EVA) was not associated with level of dependency but was associated with pain domain scores. EQ-EVA responsiveness was moderate (effect size=0.6) in the patients with a change in health status over 1 year and in reference to the relevant SF-36 item. CONCLUSION: EQ is a well-accepted tool for measuring HRQoL in this group of patients with muscular dystrophy. The prognostic interest of these subjective measures has yet to be demonstrated; however, these measures provide interesting additional information.

Health related quality of life in people with hereditary neuromuscular diseases: an investigation of test-retest agreement with comparison between two generic questionnaires, the Nottingham health profile and the short form-36 items.

The present work attempts to define reproducibility, test-retest and internal consistencies of two standardised tools that measure health related quality of life (HRQoL), specifically as they apply to hereditary neuromuscular disease (HNMD): the Nottingham health profile (NHP) and the medical outcome study 36-item short-form questionnaire (MOS SF-36). A cross sectional survey of 108 hereditary neuromuscular disease patients completed the questionnaires consecutively in the course of multidisciplinary consultations in Reims between April 2002 and February 2005. The results of the study confirm the acceptability of using generic questionnaires such as the Nottingham health profile and the SF-36, and show good reliability for these instruments. For both instruments, reproducibility (test-retest) appears excellent for the physical dimensions explored, and satisfactory for the mental dimensions. There is nonetheless a need for health related quality of life measures validated for neuromuscular disease patients. Health related quality-of-life (HRQoL) measures provide information on how patients assess their health and the care provision they are offered.

Health status in patients with Alzheimer's disease: an investigation of inter-rater agreement.

OBJECTIVE: The purpose of the present study was to examine the level of agreement between health status ratings provided by patients with Alzheimer's disease and by their proxies. BACKGROUND: Because proxy-completed responses are often necessary in assessing health outcomes for the elderly, it is necessary to determine the feasibility and potential limitations of using proxies as a patient substitutes. METHODS: To assess the potential utility of proxy responses on health status when subjects present a cognitive impairment, this study compared the responses of 70 subjects with Alzheimer's disease and those of their family and/or care provider proxy using the SF-36. Agreement between proxies and patients was measured by intraclass correlation coefficients (ICCs). RESULTS: The proportion of exact agreement between patients and proxies on the 36 items ranged from 3.3 to 41.7%. Results reveal poor to moderate agreement between patient and proxy reports. Proxy reliability varied according to the relationship of the proxy to the index subject. Agreement decreased significantly with increasing severity of dementia and with increasing severity of Physical status (Katz ADL). Agreement was better for measures of functions that are directly observable and relatively poor for more subjective measures. CONCLUSIONS: Our results confirm the importance of the information source used for patient health status.

[Family caregivers and hereditary muscular disorders: association between burden, quality of life and mental health].

OBJECTIVE: The analysis of caregiver difficulties seems important to define the life of the patient. The aim of the study was to evaluate the burden of perceived care, health-related quality of life, and mental health of family caregivers who care for patients with hereditary neuromuscular disease. MATERIALS AND METHOD: Fifty-nine family caregivers were investigated in the course of multidisciplinary consultations in Reims, France, between April 2002 and February 2005. Burden of perceived care, mental functioning and mental health were measured by answers to an burden interview instrument (Zarit Burden Inventory, ZBI), a health-related quality of life questionnaire (the SF-36 and General Health Questionnaire-12 items [GHQ-12]), and an instrument quantifying anxiety and depression (Hospital Anxiety and Depression scale [HAD]). The domain scores of the SF-36 were compared with those of the general population. Non-parametric correlations between scores were calculated. RESULTS: Thirty-five parents, 20 spouses, a sister, a grandmother and two friends cared for patients with hereditary myopathy. The average age of caregivers was 50+/-11 years; 81% were women. Ten percent of the caregivers had above-normal scores on the HAD scale, One-third perceived a significant reduction in health-related quality of life, and more half expressed a moderate or important burden according to their answers on the ZBI. Depression occurred in a great proportion of the caregivers, and they showed reduced health-related quality of life as compared with the general population. CONCLUSION: Taking into account these results, it appears useful to set up a specific support for family caregivers of patients with hereditary myopathy.

Hereditary neuromuscular disease and multicomposite subjective health status: feasibility, internal consistency and test-retest reliability in the French version of the Nottingham Health Profile, the ISPN.

OBJECTIVE: To evaluate the feasibility, internal consistency and reproducibility of the French version of the Nottingham Health Profile (NHP) completed by adults with hereditary neuromuscular disease. DESIGN: Cross-sectional study with evaluation at 15 +/- 7 days for NHP test-retest. SETTING: Multidisciplinary rehabilitation consultations in Reims. SUBJECTS: Sixty-four neuromuscular disease outpatients completed the NHP consecutively between April 2002 and December 2003. MAIN MEASURES: French version of the Nottingham Health Profile (NHP), Barthel Index and sociodemographic characteristics. RESULTS: The average completion percentages for the different dimensions was 84.2% (range 72-97%). With respect to the completion feasibility of the physical mobility subscale, 7-20% of neuromuscular disease patients failed to complete four items out of eight. In the pain subscale, the same difficulty was encountered for three items out of eight. Internal consistency as assessed by Cronbach's alpha was acceptable for the subscales physical mobility (0.88), emotional reaction (0.74), sleep (0.77), and pain (0.81); it was less reliable for the subscale social isolation (0.61), and poor for the subscale energy (0.47). Test-retest agreement measured by intraclass correlation coefficient was in all instances greater than 0.70. CONCLUSION: Some items in the pain and physical mobility subscales pose problems related to the relevance of the wording for patients confined to wheelchairs. Recoding of the measure makes it possible to avoid missing data from these dependent patients. Scores differ statistically according to the coding used. In study reports, details of such procedures should be provided for comparison of ISPN results with those from other studies in the literature.

Agreement between dementia patient report and proxy reports using the Nottingham Health Profile.

OBJECTIVE: The aim of the study was to examine the agreement between patient reports and their proxy reports (family and care provider proxies) on Health Status in a sample of patients with dementia. METHOD: Ninety-nine patients with mild to moderate dementia and proxies completed the 38-item Nottingham Health Profile (NHP) questionnaire. RESULTS: Completion rates for the different NHP dimensions ranged from 78 to 90% for the dementia subjects. Inter-rater agreement between different proxies and subject was from moderate to good for physical assessment (ICCs from 0.54 to 0.78 for physical mobility scales). Patient/family proxy concordance was moderate to good for five out of six dimensions (physical mobility, social isolation, pain, energy, sleep) and poor for emotional reaction. Family proxies systematically reported lower functioning than did patients in the four subscales assessing: physical mobility (p <0.0001), energy (p <0.005), social isolation (p <0.01) and sleep (p <0.03). Care provider proxies only estimated physical mobility as lower (p <0.0001). CONCLUSION: Age and physical status of the patient significantly affected agreement in patient-care provider proxy ratings. Thus, caution is appropriate when resorting to proxies to estimate the Health Status of a dementia patient.

[Intracavernous injections in the treatment of erectile dysfunction in spinal cord injured patients: experience with 36 patients].

OBJECTIVES: To confirm the efficiency of intracavernous injections in the treatment of erectile dysfunction in spinal cord injured (SCI) patients and to determine the mean necessary dose to obtain functional erection. MATERIALS: This prospective study concerns 36 spinal cord injured men. None of them had erectile dysfunction before the neurologic impairement. Sixty four intracavernous injections were performed. METHOD: The first injection was done with the usually recommended starting dose. The injections were then repeated with increasing dosage to archive a rigid erection. The erection was evaluated with Schramek grading. A grade 4 or 5 erection was considered as functional. RESULTS: Nine tetraplegics and 27 paraplegics were included. Twenty two were grade A in ASIA classification. The mean age was 31 years. Twenty for patients had a level above T10, 11 between T11 and L2, one below L2. Twenty seven patients obtained an erection of grade 4 or 5. Alprostadil was used 51 times, moxisylite nine times and papaverine four times. The average dose necessary to obtain a grade 4 or 5 functional erection adequate for coitus was 12.3 +/- 4.8 microgram with alprostadil and 14 +/- 5.4 mg with moxisylite. No side effects were noted. The nine left patients did not archive satisfying erection during this study. No clinical differences were noted in this population, compared with the 27 other patients. CONCLUSION: The findings confirm the efficiency of intracavernous injections in the management of erectile dysfunction in SCI. The average doses required to obtain a functional erection was 12.3 (+/- 4.8) microgram with alprostadil and 14 (+/- 5.4) mg with moxisylyte.

Comparison of nonbronchoscopic bronchoalveolar lavage to open lung biopsy for the bacteriologic diagnosis of pulmonary infections in mechanically ventilated patients.

We compared nonbronchoscopic bronchoalveolar lavage (NB-BAL) with open lung biopsy to determine the etiological diagnosis of lung infiltrates in patients requiring mechanical ventilation. NB-BAL was performed via a cuffed reusable 7F catheter generally used for right heart catheterization (BAL-C). In 13 patients, BAL-C and open lung biopsy were performed in the same lobe immediately after death when the ventilator was still functioning. No organism was cultured from BAL-C cultures when histopathologic examination of the lung showed no pneumonia and lung culture isolated no organism. Among the 10 positive BAL-C cultures, lung biopsy showed histologic pneumonia in 9 cases. Among these 9 pneumonia cases, 14 organisms were isolated in lung cultures and BAL-C correctly identified the causative agent in 13 cases. BAL-C appears to be an effective and safe procedure in the diagnosis of pulmonary infections in patients under mechanical ventilation who have previously received antibiotic therapy.

[Diagnosis of post-traumatic pleural effusion].

A rare case of post-traumatic pleural effusion is reported. A 19 year old male patient was admitted after a road traffic accident with a scalp wound, femoral shaft fracture and haematuria related to a ruptured bladder. Shortly after extubation following bladder surgical repair, the patient had to be reintubated because of acute respiratory failure. A large left-sided pleural effusion was then diagnosed. The liquid was sero-haematic and contained a high concentration of creatinine (839 mumol.l-1). Thoracic CT scan and intravenous urography displayed a left epirenal collection and a dilatation of the upper urinary tract with rupture of the renal pelvis. The surgical treatment of this urinothorax consisted of the rupture repair of the posterior diaphragm and of the urinary tract.

Epidemiology of HTLV-I in Gabon (Western Equatorial Africa).

In 1986 a survey to determine the distribution of HTLV-I infection was conducted in Gabon in a representative sample of adults and children. Five samples were taken in adults and 2 samples in children living in urban and rural areas. Samples were taken by the cluster sampling technique, i.e., clusters of randomly selected households. Sera were tested for IgG antibodies to HTLV-I by ELISA. ELISA-positive sera were retested by Western blot. The study comprised 1,874 adults and 684 children, all apparently healthy. In the adults the crude prevalence rates of anti-HTLV-I antibodies ranged from 5.0% in urban areas to 10.5% in the southern province. In rural areas, the age-adjusted prevalence rate (9.1%) was significantly higher than in urban areas (5.0%) (p less than 0.01). In children there was no significant difference between urban (2.4%) and rural (2.0%) prevalence rates. Prevalence increased with age but was not related to sex. This survey shows that HTLV-I infection is common in Gabon but varies considerably by region.

[Severe pulmonary varicella in 7 non-immunodepressed adults].

We report seven cases of seven pulmonary varicella occurring in seven adults without any previous history of known immunological deficit. In all the cases the vesicular eruption was diffuse, occurring after contact with a child presenting with benign varicella. The respiratory signs appeared five to seven days after the cutaneous signs. On admission there was significant hypoxaemia (PaO2 = 35 to 47 mmHg on air), requiring positive pressure expiration (10 to 18 cmH2O) on mechanical ventilation (4 times) or spontaneous ventilation (3 times). The pulmonary radiographs showed diffuse nodular interstitial shadowing. Treatment consisted of Acyclovir (10 mg/kg/8 h). Five patients were cured without any sequellae five to six days after ventilation. One patient died (3 months pregnant), 1 patient presented with a superinfection with staphylococcus aureus. The occurrence of respiratory signs in an adult presenting with varicella requires hospitalisation for treatment with Acyclovir and also the prevention of superinfections.

[Clinical and urodynamic results of the Burch colposuspension operation in the treatment of female urinary stress incontinence. A study apropos of 370 cases].

The surgical treatment of female genuine stress incontinence remains a not wholly solved problem. We prefer since 1980 the indirect colposuspension according to Burch as it represents 76% of our operations for genuine stress incontinence. We report 370 cases. The operation has been: isolated in 153 cases; associated with a total hysterectomy in 160 cases; associated with an indirect sacral fixation with a prosthesis of non adsorbable tissue in 57 cases. Clinical examination has always been completed with a urodynamic investigation pre-operatively and in the year following the operation. After two years or more, 188 urodynamic controls could be done. Clinical and urodynamic results are excellent and lasting after 5 years. Clinical failures represent only 4.6% of the cases and seem to be in relationship with technical defects as they occur in 78.4% of the cases in the first year following surgery. Associated sacral fixations, second hand cases, sphincter insufficiency appearing after surgery are the main factors giving way to the failures.

[Value and dangers of indomethacin used in pregnancy. Apropos of 304 treated patients].

When Indomethacin in a dosage of 175 mg/day was used to treat threatened premature labour more than 70% of cases carried on until 37 weeks. This treatment therefore is an interesting alternative treatment to beta-mimetics whose the maternal side effects can be serious. As far as the cardiovascular systems of the fetus and neonate are concerned the effects in the dosage used are negligible. On the other hand there may be renal failure which is transitory at birth when delivery has taken place while treatment was going on. The treatment should not be prolonged for more than three weeks because Indomethacin causes oligohydramnios and this can cause in its place malpositions and maldevelopment of the lungs. Finally, it is not certain whether this treatment has any effect on fetal growth causing diminished growth, possibly.
