Standard urotherapy as first-line intervention for daytime incontinence: a meta-analysis.

According to the International Children's Continence Society (ICCS) guidelines for the treatment of daytime urinary incontinence (DUI) in children and adolescents, the first-line intervention for all types of DUI is standard urotherapy (SU). Despite this recommendation there is still no meta-analysis available on the effectiveness of SU. The aim of this study is to provide a meta-analytic evaluation of the intervention. This meta-analysis is based on Odds Ratios (OR) and consists of 26 patient samples out of 19 studies (N = 1609), collected from well-established medical databases. Remission rates after SU are compared to spontaneous remission rates, which are matched to the individual follow-up period. The meta-analysis shows that SU is an effective treatment of DUI. Compared to a spontaneous remission rate of 15.40% per year, urotherapy increases the probability to recover by a factor of 7.27 (6.57 if corrected for publication bias). After exclusion of three outlying samples this effect can be generalized for all types of SU and all patient populations. Moderator analyses cannot identify variables which significantly influence the variance of effect sizes. However, RCTs seem to be associated with lower effects, even when the control group is not considered for effect size calculation. Based on the present meta-analysis, SU is an effective intervention for treating DUI in children and adolescents. Of 100 patients in 1 year, approximately 56 patients (54 if corrected for publication bias) remit after being treated with SU, while only 15 out of 100 remit spontaneously. However, to further quantify the effect size of SU in comparison to spontaneous remission rates and other treatments, additional RCTs are still needed.

Vitamin D status, trunk muscle strength, body sway, falls, and fractures among 237 postmenopausal women with osteoporosis.

The aim of this study was to identify factors associated with fractures in patients with postmenopausal osteoporosis. The overall hypothesis was that trunk muscle strength, body sway and hypovitaminosis D would influence daily activities and the likelihood of falls and fractures. - In 237 women (mean age 62.9+/-7.4 years) osteoporosis was defined by a T-score at the femoral neck below -2.5 SD. Trunk muscle strength was determined using isokinetic dynamometry and body sway was measured according to Lord et al. Limitations in everyday life were assessed and the history of falls was documented. A fracture was defined as a vertebral height reduction of more than 20% or at least 4 mm. The assessment was carried out using the Spine Deformity Index (SDI) and was confirmed by an experienced radiologist. Pearson coefficients of correlation were calculated. - After correction for age, significant associations were found for body sway and 25-hydroxyvitamin D (p<0.001), body sway and falls (p<0.001), body sway and rib fractures (p<0.01), trunk muscle strength and limitations in everyday life (p<0.001), trunk muscle strength and SDI (p<0.001), trunk muscle strength and bone density (p<0.001), and bone density and 25-hydroxyvitamin D (p<0.001). No significant correlation was found for trunk muscle strength and 25-hydroxyvitamin D (p=0.712). - Findings suggest that hypovitaminosis D is associated with increased body sway and an elevated risk for falls and falls-related fractures. Musculoskeletal rehabilitation should include strengthening exercises for the trunk muscles and training of neuromuscular co-ordination and balance.

Time since vertebral fracture: an important variable concerning quality of life in patients with postmenopausal osteoporosis.

The aim of the study was to identify factors affecting patients with postmenopausal osteoporosis who had experienced one or more vertebral fractures. The overall hypothesis was that time after fracture would influence patients' perception of pain and well-being. The sample (50 patients) was split into two groups (group A, time after fracture < or > 24 months; group B, time after fracture >24 months). A fracture was defined as a vertebral height reduction of more than 20% or at least 4 mm. The assessment was carried out using the Spine Deformity Index and was confirmed by an experienced radiologist. To assess quality of life (QoL) the following measures were used: 'well-being scale' including social extroversion as a subscale, pain scale, and limitations in everyday life. The Sense of Coherence questionnaire developed by Antonovsky measures the ability of a person to see life meaningful, manageable and explicable. This questionnaire may reflect patients' coping abilities and was introduced to establish whether these influence the perception of pain and well-being after vertebral fracture. Variance and covariance analysis was carried out using SPSS (version 6.1). Differences between groups A and B were found for perception of average pain (p = 0.017), social extroversion (p = 0.003) and well-being (p = 0.024). No differences were found for limitations in everyday life (p = 0.607), Sense of Coherence (p = 0.638), the Spine Deformity Index (p = 0.171) and loss of height (p = 0.619). All analyses were corrected for age. Concurrent medication was not found to influence the results. Findings suggest that time after fracture is an important variable when considering QoL and well-being after vertebral fracture and should, therefore, be considered in future studies.
