The importance of these issues depends on the use of the data and on the problems they have to address. If the evaluation is satisfactory with respect to the above-mentioned factors relevant to the particular study, the data source could be a very cost-effective way of solving the research problem.
Study design: Cross-sectional questionnaire study. Objectives: To develop and validate a symptom-based score for neurogenic bowel dysfunction (NBD): NBD score. Setting: University Hospital of Aarhus, Denmark. Methods: A questionnaire including questions about background parameters (n ¼ 8), faecal incontinence (n ¼ 10), constipation (n ¼ 10), obstructed defecation (n ¼ 8), and impact on quality of life (QOL) (n ¼ 3) was sent to 589 Danish spinal cord injured (SCI) patients. The reproducibility and validity of each item was tested in 20 and 18 patients, respectively. Associations between items and impact on QOL were determined by logistic regression analysis. The NBD score was constructed from items with acceptable reproducibility and validity that were significantly associated with impact on QOL. Based on odds ratios for associations between items and impact on QOL, each item was given a corresponding number of points in the NBD score. Results: A total of 424 SCI patients responded. The following 10 items met the criteria above: frequency of bowel movements (0-6 points), headache, perspiration or discomfort before or during defecation (0-2 points), tablets and drops against constipation (0-2 points each), time used for each defecation (0-7 points), frequency of digital stimulation or evacuation (0-6 points), frequency of faecal incontinence (0-13 points), medication against faecal incontinence (0-4 points), flatus incontinence (0-2 points) and perianal skin problems (0-3 points). Differences in NBD score among patients reporting no, little, some or major impact on QOL were statistically significant (all Po0.001). Conclusion: Based on valid and reproducible questions, we have constructed a score for NBD that is correlated to impact on QOL.
Colorectal dysfunction is very common among spinal cord-injured patients, often causing restriction on social activities and quality of life. Therefore, these problems deserve more attention in the treatment of spinal cord-injured patients.
The present study was designed to test the relation between stressful life events experienced during pregnancy and the risk of preterm delivery and shortened duration of pregnancy. We collected data prospectively in a general population sample, including repeated questionnaire measures of exposure to stressful life events during pregnancy. Between August 1989 and September 1991, 8,719 Danish-speaking women with singleton pregnancies attended antenatal care. Of these women, 5,873 (67%) completed all questionnaires. When indicating an event, the woman was asked to rate the amount of stress induced by this event. Measurement of gestational duration was primarily based on early ultrasound scan. When we evaluated life events independently of the individual's appraisal, we found no association with duration of gestation or risk of preterm delivery. In contrast, life events assessed by the subject as highly stressful were associated with shorter mean duration of gestation and increased risk of preterm delivery. This association was observed primarily with events experienced between the 16th and 30th week of gestation. Women who had one or more highly stressful life events had a risk of preterm delivery 1.76 times greater than those without stressful events (95% confidence interval = 1.15-2.71). We found no evidence for a buffering effect of social support.
Objective: To assess the efficacy of ultrasound treatment for mild to moderate idiopathic carpal tunnel syndrome. Design: Randomised, double blind, "sham" controlled trial with assessments at baseline, after 2 weeks' and 7 weeks' treatment, and at a follow up assessment 6 months later (8 months after baseline evaluation). Setting: Outpatient clinic of a university department of physical medicine and rehabilitation in Vienna. Subjects: 45 patients with mild to moderate bilateral carpal tunnel syndrome as verified by electroneurography. Intervention: 20 sessions of ultrasound (active) treatment (1 MHz, 1.0 W/cm 2 , pulsed mode 1:4, 15 minutes per session) applied to the area over the carpal tunnel of one wrist, and indistinguishable sham ultrasound treatment applied to the other. The first 10 treatments were performed daily (5 sessions/week); 10 further treatments were twice weekly for 5 weeks. Main outcome measures: Score of subjective symptom ratings assessed by visual analogue scale; electroneurographic measures (for example, motor distal latency and sensory antidromic nerve conduction velocity). Results: Improvement was significantly more pronounced in actively treated than in sham treated wrists for both subjective symptoms (P < 0.001, paired t test) and electroneurographic variables (motor distal latency P < 0.001, paired t test; sensory antidromic nerve conduction velocity P < 0.001, paired t test). Effects were sustained at 6 months' follow up. Conclusion: Results suggest there are satisfying short to medium term effects due to ultrasound treatment in patients with mild to moderate idiopathic carpal tunnel syndrome. Findings need to be confirmed, and ultrasound treatment will have to be compared with standard conservative and invasive treatment options.
BackgroundAlthough the debate on the safety and women's right of choice to a home delivery vs. hospital delivery continues in the developed countries, an undesirable outcome of home delivery, such as high maternal and perinatal mortality, is documented in developing countries. The objective was to study whether socio-economic factors, distance to maternity hospital, ethnicity, type and size of family, obstetric history and antenatal care received in present pregnancy affected the choice between home and hospital delivery in a developing country.MethodsThis cross-sectional study was done during June, 2001 to January 2002 in an administratively and geographically well-defined territory with a population of 88,547, stretching from urban to adjacent rural part of Kathmandu and Dhading Districts of Nepal with maximum of 5 hrs of distance from Maternity hospital. There were no intermediate level of private or government hospital or maternity homes in the study area. Interviews were carried out on 308 women who delivered within 45 days of the date of the interview with a pre-tested structured questionnaire.ResultsA distance of more than one hour to the maternity hospital (OR = 7.9), low amenity score status (OR = 4.4), low education (OR = 2.9), multi-parity (OR = 2.4), and not seeking antenatal care in the present pregnancy (OR = 4.6) were statistically significantly associated with an increased risk of home delivery. Ethnicity, obstetric history, age of mother, ritual observance of menarche, type and size of family and who is head of household were not statistically significantly associated with the place of delivery.ConclusionsThe socio-economic standing of the household was a stronger predictor of place of delivery compared to ethnicity, the internal family structure such as type and size of family, head of household, or observation of ritual days by the mother of an important event like menarche. The results suggested that mothers, who were in the low-socio-economic scale, delivered at home more frequently in a developing country like Nepal.
