State and trait anxiety in children with incontinence and their parents.

BACKGROUND: Maternal anxiety increases the risk for incontinence in children. The aim was to analyze anxiety in children with incontinence and their parents before (t1) and after 6 months of incontinence treatment (t2). METHODS: 40 children with incontinence and 40 controls completed the State-trait Anxiety Inventory for Children, their parents the Child Behavior Checklist (CBCL) and the State-trait Anxiety Inventory at baseline (t1) and 6 months later (follow-up, t2). Psychiatric disorders were assessed by a standardized parental diagnostic interview (Kinder-DIPS), IQ was tested by a one-dimensional test. All children were neurologically examined. Children with incontinence underwent a guideline-based treatment during the 6 months. RESULTS: At baseline, child and parental state and trait anxiety scores, as well as all CBCL scores were significantly higher in the patient group compared to the control group. At t2, parental anxiety, CBCL scores, and child trait anxiety were significantly higher in patients versus controls, whereas child state anxiety decreased, and parental state anxiety increased from t1 to t2. CONCLUSIONS: Incontinence and anxiety are associated. While state anxiety decreases, trait anxiety can remain stable over time. Higher levels of anxiety can influence incontinence treatment and should be assessed in every patient.

Bladder and bowel control in a population-based sample: Associations to quality of life and behavioral problems of 4-6-year-old children participating in the German Health Interview and Examination Survey (KiGGS).

BACKGROUND: Prevalence rates for psychiatric comorbidities are high in incontinent children. We analyzed data from the KiGGS survey in order to assess the rate of preschool children with delayed or regular continence, the mean age of gaining continence, psychiatric problems, and quality of life in a nation-wide, representative sample. METHODS: Parental questionnaire data of 3875 preschool children (4-6 years) were analyzed. Percentages of children with daytime, nighttime, and complete continence, and mean ages of gaining continence were calculated. Psychological and behavioral problems (SDQ), as well as Quality of life (KINDL-R), were assessed. RESULTS: 16.9% showed delayed gaining of continence. Percentages of children with nighttime bladder continence were lower for boys (76.3%) than for girls (80.6%), and lower for children without (78.2%) than those with a migration status (79.2%). Complete continence was gained by more girls (83.9%) than boys (78.2%), more children from the former East Germany (82.4%) than former West Germany (81.1%), and by more migrants (82.7%) than nonmigrants (81.9%). Girls, children living in the former East of Germany, and migrants achieved continence consistently at an earlier age. Children with incontinence or continence ≥4 years showed significantly more psychological problems, less prosocial behavior and low quality of life. CONCLUSION: The age at gaining continence is moderated by gender, German region, and migration status. Delayed achievement of continence is associated with more psychological problems and a lower quality of life. The importance of effective treatment of incontinence is emphasized by the results of this study.

Effects of feedback-based visual line-orientation discrimination training for visuospatial disorders after stroke.

BACKGROUND: Patients with right or more rarely left parietotemporal lesions after stroke may have profound visuospatial disorders that impair activities of daily living (ADL) and long-term outcome. Clinical studies indicate improvements with systematic training of perception. Studies of perceptual learning in healthy persons suggest rapid improvements in perceptual learning of spatial line orientation with partial transfer to nontrained line orientations. OBJECTIVE: The authors investigated a novel feedback-based perceptual training procedure for the rehabilitation of patients after stroke. METHODS: In an uncontrolled trial, 13 participants showing profound deficits in line orientation and related visuospatial tasks within 12 to 28 weeks of onset performed repetitive feedback-based, computerized training of visual line orientation over 4 weeks of treatment. Visual line-orientation discrimination and visuospatial and visuoconstructive tasks were assessed before and after training. RESULTS: The authors found (a) rapid improvements in trained but also in nontrained spatial orientation tests in all 13 participants, partially up to a normal level; (b) stability of the obtained improvements at 2-month follow-up; (c) interocular transfer of training effects to the nontrained eye in 2 participants suggesting a central, postchiasmatic locus for this perceptual improvement; and (d) graded transfer of improvements to related spatial tasks, such as horizontal writing, analog clock reading, and visuoconstructive capacities but no transfer to unrelated measures of visual performance. CONCLUSIONS: These results suggest the potential for treatment-induced improvements in visuospatial deficits by feedback-based, perceptual orientation training as a component of rehabilitation after stroke.

Minor adverse effects of galvanic vestibular stimulation in persons with stroke and healthy individuals.

OBJECTIVE: Galvanic vestibular stimulation (GVS) induces polarity-specific activations in the vestibular nerves and upstream in the vestibular and parietotemporal cortices as well as sub-cortical regions. This makes it an attractive technique for cognitive neuromodulation. However, systematic studies regarding adverse effects of GVS are unavailable. Thus, this study assessed adverse effects during and after sub-sensory GVS (mean: 0.6 mA) and GVS with 1.5 mA. METHODS: Two hundred and fifty-five GVS sessions delivered to 55 persons with stroke and 30 healthy individuals were analysed using a 34-item-questionnaire including potential symptoms and rating scales for adverse effects. RESULTS: The most frequent symptoms during and after GVS were slight itching (mean: 10.2%) and tingling (mean: 10.7%) underneath the electrodes. Healthy individuals and persons with stroke did not differ in their incidence and rated intensity of adverse effects, nor did persons with or without unilateral spatial neglect. Adverse effects were found more frequently with GVS with 1.5 mA as with sub-sensory GVS. Participants were unable to differentiate real from sham conditions during sub-sensory GVS. Importantly, neither seizures nor vertigo or nausea were observed. CONCLUSION: Sub-sensory GVS and GVS with 1.5 mA induce very few and mild adverse effects in healthy and persons with stroke and are safe when safety guidelines are followed.
