Etiology and management of fecal incontinence.

Abstract: Fecal incontinence is a challenging condition of diverse etiology and devastating psychosocial impact. Multiple mechanisms may be involved in its pathophysiology, such as altered stool consistency and delivery of contents to the rectum, abnormal rectal capacity or compliance, decreased anorectal sensation, and pelvic floor or anal sphincter dysfunction. A detailed clinical history and physical examination are essential. Anorectal manometry, pudendal nerve latency studies, and electromyography are part of the standard primary evaluation. The evaluation of idiopathic fecal incontinence may require tests such as cinedefecography, spinal latencies, and anal mucosal electrosensitivity. These tests permit both objective assessment and focused therapy. Appropriate treatment options include biofeedback and sphincteroplasty. Biofeedback has resulted in 90 percent reduction in episodes of incontinence in over 60 percent of patients. Overlapping anterior sphincteroplasty has been associated with good to excellent results in 70 to 90 percent of patients. The common denominator between the medical and surgical treatment groups is the necessity of pretreatment physiologic assessment. It is the results of these tests that permit optimal therapeutic assignment. For example, pudendal nerve terminal motor latencies (PNTML) are the most important predictor factor of functional outcome. However, even the most experienced examiner's digit cannot assess PNTML. In the absence of pudendal neuropathy, sphincteroplasty is an excellent option. If neuropathy exists, however, then postanal or total pelvic floor repair remain viable surgical options for the treatment of idiopathic fecal incontinence. In the absence of an adequate sphincter muscle, encirclement procedures using synthetic materials or muscle transfer techniques might be considered. Implantation of a stimulating electrode into the gracilis neosphincter and artificial sphincter implantation are other valid alternatives. The final therapeutic option is fecal diversion. This article reviews the current status of the etiology and incidence of incontinence as well as the evaluation and treatment of this disabling condition.

Motor recovery after stroke: a systematic review

Abstract: Loss of functional movement is a common consequence of stroke for which a wide range of interventions has been developed. In this Review, we aimed to provide an overview of the available evidence on interventions for motor recovery after stroke through the evaluation of systematic reviews, supplemented by recent randomised controlled trials. Most trials were small and had some design limitations. Improvements in recovery of arm function were seen for constraint-induced movement therapy, electromyographic biofeedback, mental practice with motor imagery, and robotics. Improvements in transfer ability or balance were seen with repetitive task training, biofeedback, and training with a moving platform. Physical fitness training, high-intensity therapy (usually physiotherapy), and repetitive task training improved walking speed. Although the existing evidence is limited by poor trial designs, some treatments do show promise for improving motor recovery, particularly those that have focused on high-intensity and repetitive task-specific practice.

Psychological therapies for the management of chronic and recurrent pain in children and adolescents

Abstract: Background This is an update of the original Cochrane review first published in Issue 1, 2003, and previously updated in 2009 and 2012. Chronic pain affects many children, who report severe pain, disability, and distressed mood. Psychological therapies are emerging as effective interventions to treat children with chronic or recurrent pain. This update focuses specifically on psychological therapies delivered face-to-face, adds new randomised controlled trials (RCTs), and additional data from previously included trials. Objectives There were three objectives to this review. First, to determine the effectiveness on clinical outcomes of pain severity, disability, depression, and anxiety of psychological therapy delivered face-to-face for chronic and recurrent pain in children and adolescents compared with active treatment, waiting-list, or standard medical care. Second, to evaluate the impact of psychological therapies on depression and anxiety, which were previously combined as 'mood'. Third, we assessed the risk of bias of the included studies and the quality of outcomes using the GRADE criteria. Search methods Searches were undertaken of CENTRAL, MEDLINE, EMBASE, and PsycINFO. We searched for further RCTs in the references of all identified studies, meta-analyses, and reviews. Trial registry databases were also searched. The date of most recent search was January 2014. Selection criteria RCTs with at least 10 participants in each arm post-treatment comparing psychological therapies with active treatment, standard medical care, or waiting-list control for children or adolescents with episodic, recurrent or persistent pain were eligible for inclusion. Only trials conducted in person (face-to-face) were considered. Studies that delivered treatment remotely were excluded from this update. Data collection and analysis All included studies were analysed and the quality of outcomes were assessed. All treatments were combined into one class, psychological treatments. Pain conditions were split into headache and non-headache. Both conditions were assessed on four outcomes: pain, disability, depression, and anxiety. Data were extracted at two time points; post-treatment (immediately or the earliest data available following end of treatment) and at follow-up (between three and 12 months post-treatment). Main results Seven papers were identified in the updated search. Of these papers, five presented new trials and two presented follow-up data for previously included trials. Five studies that were previously included in this review were excluded as therapy was delivered remotely. The review thus included a total of 37 studies. The total number of participants completing treatments was 2111. Twenty studies addressed treatments for headache (including migraine); nine for abdominal pain; two for mixed pain conditions including headache pain, two for fibromyalgia, two for recurrent abdominal pain or irritable bowel syndrome, and two for pain associated with sickle cell disease. Analyses revealed psychological therapies to be beneficial for children with chronic pain on seven outcomes. For headache pain, psychological therapies reduced pain post-treatment and at follow-up respectively (risk ratio (RR) 2.47, 95% confidence interval (CI) 1.97 to 3.09, z = 7.87, p 0.05). At follow-up, only one study was eligible, therefore no analysis was possible and no conclusions can be drawn. Analyses revealed a small beneficial effect for anxiety post-treatment (SMD -0.33, 95% CI -0.61 to -0.04, z = 2.25, p 0.05). Analyses revealed two beneficial effects of psychological treatment for children with non-headache pain. Pain was found to improve post-treatment (SMD -0.57, 95% CI -0.86 to -0.27, z = 3.74, p 0.05). Psychological therapies also had a beneficial effect for disability post-treatment (SMD -0.45, 95% CI -0.71 to -0.19, z = 3.40, p 0.05). No effect was found for depression or anxiety post-treatment (SMD -0.07, 95% CI -0.30 to 0.17, z = 0.54, p > 0.05; SMD -0.15, 95% CI -0.36 to 0.07, z = 1.33, p > 0.05) or at follow-up (SMD 0.06, 95% CI -0.16 to 0.28, z = 0.53, p > 0.05; SMD 0.05, 95% CI -0.24 to 0.33, z = 0.32, p > 0.05). Authors' conclusions Psychological treatments delivered face-to-face are effective in reducing pain intensity and disability for children and adolescents (<18 years) with headache, and therapeutic gains appear to be maintained, although this should be treated with caution for the disability outcome as only two studies could be included in the follow-up analysis. Psychological therapies are also beneficial at reducing anxiety post-treatment for headache. For non-headache conditions, psychological treatments were found to be beneficial for pain and disability post-treatment but these effects were not maintained at follow-up. There is limited evidence available to estimate the effects of psychological therapies on depression and anxiety for children and adolescents with headache and non-headache pain. The conclusions of this update replicate and add to those of the previous review which found that psychological therapies were effective in reducing pain intensity for children with headache and non-headache pain conditions, and these effects were maintained at follow-up for children with headache conditions.
