Abstract
PURPOSE Inguinal hernia repair using surgical mesh is a very common surgical operation. Currently, there is no consensus on the best technique for mesh fixation. We conducted an overview of existing systematic reviews (SRs) of randomised controlled trials to compare the risk of chronic pain and recurrence following open and laparoscopic inguinal hernia repairs using various mesh fixation techniques. METHODS We searched major electronic databases in April 2020 and assessed the methodological quality of identified reviews using the AMSTAR-2 tool. RESULTS We identified 20 SRs of variable quality assessing suture, self-gripping, glue, and mechanical fixation. Across reviews, the risk of chronic pain after open mesh repair was lower with glue fixation than with suture and comparable between self-gripping and suture. Incidence of chronic pain was lower with glue fixation than with mechanical fixation in laparoscopic repairs. There were no significant differences in recurrence rates between fixation techniques in open and laparoscopic mesh repairs, although fewer recurrences were reported with suture. Many reviews reported wide confidence intervals around summary estimates. Despite no clear evidence of differences among techniques, two network meta-analyses (one assessing open repairs and one laparoscopic repairs) ranked glue fixation as the best treatment for reducing pain and suture for reducing the risk of recurrence. CONCLUSION Glue fixation may be effective in reducing the incidence of chronic pain without increasing the risk of recurrence. Future research should consider both the effectiveness and cost-effectiveness of fixation techniques alongside the type of mesh and the size and location of the hernia defect.

Abstract
OBJECTIVES To assess the effectiveness and cost-effectiveness of HealOzone (CurOzone USA Inc., Ontario, Canada) for the management of pit and fissure caries, and root caries. The complete HealOzone procedure involves the direct application of ozone gas to the caries lesion on the tooth surface, the use of a remineralising solution immediately after application of ozone and the supply of a 'patient kit', which consists of toothpaste, oral rinse and oral spray all containing fluoride. DATA SOURCES Electronic databases up to May 2004 (except Conference Papers Index, which were searched up to May 2002). REVIEW METHODS A systematic review of the effectiveness of HealOzone for the management of tooth decay was carried out. A systematic review of existing economic evaluations of ozone for dental caries was also planned but no suitable studies were identified. The economic evaluation included in the industry submission was critically appraised and summarised. A Markov model was constructed to explore possible cost-effectiveness aspects of HealOzone in addition to current management of dental caries. RESULTS Five full-text reports and five studies published as abstracts met the inclusion criteria. The five full-text reports consisted of two randomised controlled trials (RCTs) assessing the use of HealOzone for the management of primary root caries and two doctoral theses of three unpublished randomised trials assessing the use of HealOzone for the management of occlusal caries. Of the abstracts, four assessed the effects of HealOzone for the management of occlusal caries and one the effects of HealOzone for the management of root caries. Overall, the quality of the studies was modest, with many important methodological aspects not reported (e.g. concealment of allocation, blinding procedures, compliance of patients with home treatment). In particular, there were some concerns about the choice of statistical analyses. In most of the full-text studies analyses were undertaken at lesion level, ignoring the clustering of lesions within patients. The nature of the methodological concerns was sufficient to raise doubts about the validity of the included studies' findings. A quantitative synthesis of results was deemed inappropriate. On the whole, there is not enough evidence from published RCTs on which to judge the effectiveness of ozone for the management of both occlusal and root caries. The perspective adopted for the study was that of the NHS and Personal Social Services. The analysis, carried out over a 5-year period, indicated that treatment using current management plus HealOzone cost more than current management alone for non-cavitated pit and fissure caries (40.49 pounds versus 24.78 pounds), but cost less for non-cavitated root caries ( 14.63 pounds versus 21.45 pounds). Given the limitations of the calculations these figures should be regarded as illustrative, not definitive. It was not possible to measure health benefits in terms of quality-adjusted life-years, due to uncertainties around the evidence of clinical effectiveness, and to the fact that the adverse events avoided are transient (e.g. pain from injection of local anaesthetic, fear of the drill). One-way sensitivity analysis was applied to the model. However, owing to the limitations of the economic analysis, this should be regarded as merely speculative. For non-cavitated pit and fissure caries, the HealOzone option was always more expensive than current management when the probability of cure using the HealOzone option was 70% or lower. For non-cavitated root caries the costs of the HealOzone comparator were lower than those of current management only when cure rates from HealOzone were at least 80%. The costs of current management were higher than those of the HealOzone option when the cure rate for current management was 40% or lower. One-way sensitivity analysis was also performed using similar NHS Statement of Dental Remuneration codes to those that are used in the industry submission. This did not alter the results for non-cavitated pit fissure caries as the discounted net present value of current management remained lower than that of the HealOzone comparator ( 22.65 pounds versus 33.39 pounds). CONCLUSIONS Any treatment that preserves teeth and avoids fillings is welcome. However, the current evidence base for HealOzone is insufficient to conclude that it is a cost-effective addition to the management and treatment of occlusal and root caries. To make a decision on whether HealOzone is a cost-effective alternative to current preventive methods for the management of dental caries, further research into its clinical effectiveness is required. Independent RCTs of the effectiveness and cost-effectiveness of HealOzone for the management of occlusal caries and root caries need to be properly conducted with adequate design, outcome measures and methods for statistical analyses.

Abstract
BACKGROUND Faecal incontinence is a common and potentially distressing disorder of childhood. OBJECTIVES To assess the effects of behavioural and/or cognitive interventions for the management of faecal incontinence in children. SEARCH STRATEGY We searched the Cochrane Incontinence Group Specialised Trials Register (searched 1 February 2006). SELECTION CRITERIA Randomised and quasi-randomised trials of behavioural and/or cognitive interventions with or without other treatments for the management of faecal incontinence in children. DATA COLLECTION AND ANALYSIS Reviewers selected studies from the literature, assessed study quality, and extracted data. Data were combined in a meta-analysis when appropriate. MAIN RESULTS Eighteen randomised trials with a total of 1168 children met the inclusion criteria. Sample sizes were generally small. All studies but one investigated children with functional faecal incontinence. Interventions varied amongst trials and few outcomes were shared by trials addressing the same comparisons. Combined results of nine trials showed higher rather than lower rates of persisting symptoms of faecal incontinence up to 12 months when biofeedback was added to conventional treatment (OR 1.11 CI 95% 0.78 to 1.58). This result was consistent with that of two trials with longer follow-up (OR 1.31 CI 95% 0.80 to 2.15). In one trial the adjunct of anorectal manometry to conventional treatment did not result in higher success rates in chronically constipated children (OR 1.40 95% CI 0.72 to 2.73 at 24 months). In one small trial the adjunct of behaviour modification to laxative therapy was associated with a significant reduction in children's soiling episodes at both the three month (OR 0.14 CI 95% 0.04 to 0.51) and the 12 month assessment (OR 0.20 CI 95% 0.06 to 0.65). AUTHORS' CONCLUSIONS There is no evidence that biofeedback training adds any benefit to conventional treatment in the management of functional faecal incontinence in children. There was not enough evidence on which to assess the effects of biofeedback for the management of organic faecal incontinence. There is some evidence that behavioural interventions plus laxative therapy, rather than laxative therapy alone, improves continence in children with functional faecal incontinence associated with constipation.

Abstract
OBJECTIVES To assess the effectiveness and cost-effectiveness of single photon emission computed tomography (SPECT) myocardial perfusion scintigraphy for the diagnosis and management of angina and myocardial infarction (MI). DATA SOURCES Major electronic databases. REVIEW METHODS Two reviewers independently extracted data and assessed study quality. A decision tree model was used to model the diagnosis decision and a Markov model was developed for the management of patients with suspected coronary artery disease. Costs for the treatments and interventions within strategies were derived from the literature and expressed in 2001-02 pounds sterling. Quality-adjusted life-year (QALY) weights for the different Markov model states were also obtained from the literature. RESULTS Twenty-one diagnostic and 46 prognostic studies were included, plus two studies comparing SPECT with electrocardiography (ECG)-gated SPECT and one study comparing SPECT with attenuation-corrected SPECT. The diagnostic values of SPECT were generally higher than those of stress ECG, indicating that SPECT provided a better diagnostic performance. SPECT also provided higher positive and lower negative likelihood ratios than stress ECG but heterogeneity was evident among studies. The subgroup of studies including patients with previous MI tended to report a better diagnostic performance for SPECT than stress ECG, but there were too few studies to assess this reliably. The extent and size of the perfusion defect, and whether reversible or fixed, were important factors in predicting future cardiac events such as cardiac death or non-fatal MI. SPECT may be able to identify lower risk patients for whom coronary angiography (CA) might be avoided. Normal SPECT scans were associated with a benign prognosis and the option of medical rather than invasive management. Four studies of patients post-MI reported SPECT to be valuable in stratifying patients into at-risk groups for further cardiac events. The two studies comparing SPECT with ECG-gated SPECT, one diagnostic and the other prognostic, found in favour of gated SPECT. The study comparing SPECT with attenuation-corrected SPECT reported the latter to be more accurate. The systematic review of economic evaluations indicated that strategies involving SPECT were likely either to be dominant or to produce more QALYs at an acceptable cost. There was less agreement about which of the strategies involving SPECT was optimal. The model suggested that, for low prevalence, the incremental cost per unit of output (true positives diagnosed, accurate diagnosis, QALY) for the move from stress ECG-SPECT-CA and from stress ECG-CA to SPECT-CA might be considered worthwhile. Even after allowing for different values for sensitivity or specificity, the least costly and least effective strategy was stress ECG-SPECT-CA. The sensitivity analysis suggested that the cost-effectiveness of SPECT-CA improved if it was assumed that SPECT results allowed for the adoption of a management strategy without recourse to CA. As the time horizon reduced, the incremental cost per QALY increased (as the cost of initial diagnosis and treatment were not offset by survival and quality of life gains). CONCLUSIONS There was a considerable variability in terms of measurement of outcomes, management, setting and patient characteristics, however the direction of evidence tended to favour SPECT in terms of test sensitivity, although these conclusions are based on a relatively small number of diagnostic studies. SPECT, in a variety of settings and patient populations, provided valuable independent and incremental prognostic information to that provided by stress ECG and/or CA that helped to risk-stratify patients and influence the way in which their condition was managed. However, all of the prognostic studies were observational studies and may be biased by unknown confounding factors. Although the ECG-gated and attenuation-corrected SPECT findings seem promising, it is difficult to draw conclusions from so few studies. Further research is needed on the effectiveness and cost-effectiveness, diagnostically and prognostically, of (a) gated and attenuation-corrected SPECT compared with standard SPECT, (b) standard SPECT compared with stress echocardiography and (c) the uncertainty surrounding the results presented in the cost-effectiveness analysis.

Abstract
BACKGROUND Faecal incontinence is a common symptom which causes significant distress and reduction in quality of life. Available treatment options for faecal incontinence include conservative treatments (biofeedback, pelvic floor muscle training, dietary manipulation or drug therapy) or surgical treatments (e.g. sphincter repair, post anal repair, neosphincter). Drug treatment is often given either alone or in combination with other treatment modalities. OBJECTIVES To assess the effects of drug therapy for the treatment of faecal incontinence. In particular, to assess the effects of individual drugs relative to placebo or other drugs, and to compare drug therapy with other treatment modalities. SEARCH STRATEGY We searched the Cochrane Incontinence Group trials register (January 2003) and the reference lists of relevant articles. Date of the most recent search: January 2003. SELECTION CRITERIA All randomised or quasi-randomised controlled trials of the use of pharmacological agents for the treatment of faecal incontinence in adults. DATA COLLECTION AND ANALYSIS Working independently, reviewers selected studies from the literature, assessed the methodological quality of each trial, and extracted data. MAIN RESULTS Eleven trials were identified for inclusion in this review. Nine trials were of cross-over design. Seven trials included only people with faecal incontinence related to liquid stool (either chronic diarrhoea or following ileoanal pouch surgery). Three trials (total 58 participants) compared topical phenylephrine gel with placebo. Two trials (56 participants) compared loperamide with placebo. One trial (11 participants) compared loperamide oxide with placebo. One trial (15 participants) compared diphenoxylate plus atropine with placebo. One trial (17 participants) compared sodium valproate with placebo. One trial (30 participants) compared loperamide with codeine with diphenoxylate plus atropine. Two further trials (total 265 participants) assessed the use of lactulose in elderly people.No studies comparing drugs with other treatment modalities were identified. There was limited evidence that antidiarrhoeal drugs and drugs which enhance anal sphincter tone may reduce faecal incontinence in patients with liquid stools. However, the trials were small and of short duration. REVIEWER'S CONCLUSIONS The small number of trials identified for this review assessed several different drugs in a variety of patient populations. The focus of most of the included trials was on the treatment of diarrhoea, rather than faecal incontinence. There is little evidence to guide clinicians in the selection of drug therapies for faecal incontinence. Larger, well-designed controlled trials, which include clinically important outcome measures, are required.

Abstract
BACKGROUND People with neurological disease have a much higher risk of both faecal incontinence and constipation than the general population. There is often a fine dividing line between the two conditions, with any management intended to ameliorate, one risking precipitating the other. Bowel problems are observed to be the cause of much anxiety and may reduce quality of life in these people. Current bowel management is largely empirical with a limited research base. OBJECTIVES To determine the effects of management strategies for faecal incontinence and constipation in people with neurological diseases affecting the central nervous system. SEARCH STRATEGY We searched the Cochrane Incontinence Group Trials Register, the Cochrane Controlled Trials Register, MEDLINE, EMBASE and all reference lists of relevant articles. Date of the most recent searches: May 2000. SELECTION CRITERIA All randomised or quasi-randomised trials evaluating any types of conservative, or surgical measure for the management of faecal incontinence and constipation in people with neurological diseases were selected. Specific therapies for the treatment of neurological diseases that indirectly affect bowel dysfunction have also been considered. DATA COLLECTION AND ANALYSIS All three reviewers assessed the methodological quality of eligible trials and two reviewers independently extracted data from included trials using a range of pre-specified outcome measures. MAIN RESULTS Only seven trials were identified by the search strategy and all were small and of poor quality. Oral medications for constipation were the subject of four trials. Cisapride does not seem to have clinically useful effects in people with spinal cord injuries (two trials). Psyllium was associated with increased stool frequency in people with Parkinson's disease but not altered colonic transit time (one trial). Some rectal preparations to initiate defecation produced faster results than others (one trial). Different time schedules for administration of rectal medication may produce different bowel responses (one trial). Mechanical evacuation may be more effective than oral or rectal medication (one trial). The clinical significance of any of these results is difficult to interpret. REVIEWER'S CONCLUSIONS It is not possible to draw any recommendation for bowel care in people with neurological diseases from the trials included in this review. Bowel management for these people must remain empirical until well-designed controlled trials with adequate numbers and clinically relevant outcome measures become available.

Abstract
BACKGROUND Faecal soiling is a common and potentially distressing disorder of childhood. OBJECTIVES To assess the effects of behavioural and/or cognitive interventions for the management of defaecation disorders in children. SEARCH STRATEGY The following databases were searched: the Cochrane Incontinence Group Trials Register (March 2001), the Cochrane Controlled Trials Register (Issue 4, 2000), The Enuresis Resource and Information Centre Register of studies of encopresis and soiling, AMED (1985 to April 2000), PsycINFO (1887 to June 2000), Index to Theses - Great Britain and Ireland (October 2000), Dissertation Abstracts (November 2000), EMBASE (January 1998 to October 1999), SIGLE (January 1980 to December 1996), BIOSIS (January 1998 to March 1999), Science Citation Index (January 1998 to March 1999), ISTP (January 1982 to March 1999). Date of the most recent searches: March 2001. Bibliographies of trials retrieved were also searched and colleagues and experts in the field were contacted for information. SELECTION CRITERIA Randomised and quasi-randomised trials of behavioural and/or cognitive interventions with or without other treatments for the management of defaecation disorders in children. DATA COLLECTION AND ANALYSIS Two reviewers independently selected studies from the literature. One reviewer assessed the methodological quality of eligible trials and extracted data. Data were combined in a meta-analysis when appropriate. MAIN RESULTS Sixteen randomised trials with a total of 843 children met the inclusion criteria. Sample sizes were generally small. Interventions varied among trials and few outcomes were shared by trials addressing the same comparisons. The synthesis of data from eight trials showed higher rather than lower rates of persisting problem up to 12 months when biofeedback was added to conventional treatment (OR 1.34 CI 95% 0.92 to 1.94). In two trials significantly more encopretic children receiving behavioural intervention plus laxative therapy improved compared with those receiving behavioural intervention alone at both the 6-month (OR 0.51 CI 95% 0.29 to 0.89) and the 12-month follow-up (OR 0.52 CI 95% 0.30 to 0.93). Similarly in another trial the addition of behaviour modifications to laxative therapy was associated with a marked reduction in children's soiling episodes (OR 0.14 CI 95% 0.04 to 0.51). REVIEWER'S CONCLUSIONS There is no evidence that biofeedback training adds any benefit to conventional treatment in the management of encopresis and constipation in children. There is some evidence that behavioural intervention plus laxative therapy, rather than behavioural intervention or laxative therapy alone, improves continence in children with primary and secondary encopresis.

Abstract
BACKGROUND Faecal incontinence is a particularly embarrassing and distressing condition with significant medical, social and economic implications. Sphincter exercises and biofeedback therapy have been used to treat the symptoms of people with faecal incontinence. However, standards of treatment are still lacking and the magnitude of alleged benefits has yet to be established. OBJECTIVES To determine the effects of biofeedback and/or anal sphincter exercises/pelvic floor muscle training for the treatment of faecal incontinence in adults. SEARCH STRATEGY We searched the Cochrane Incontinence Group trials register, the Cochrane Controlled Trials Register, Medline, Embase and all reference lists of relevant articles up to November 1999. Date of the most recent searches: November 1999. SELECTION CRITERIA All randomised or quasi-randomised trials evaluating biofeedback and/or anal sphincter exercises in adults with faecal incontinence. DATA COLLECTION AND ANALYSIS Three reviewers assessed the methodological quality of eligible trials and two reviewers independently extracted data from included trials. A wide range of outcome measures were considered. MAIN RESULTS Only five eligible studies were identified with a total of 109 participants. In the majority of trials methodological quality was poor or uncertain. All trials were small and employed a limited range of outcome measures. Follow-up information was not consistently reported amongst trials. Only two trials provided data in a form suitable for statistical analyses. There are suggestions that rectal volume discrimination training improves continence more than sham training and that anal biofeedback combined with exercises and electrical stimulation provides more short-term benefits than vaginal biofeedback and exercises for women with obstetric-related faecal incontinence. Further conclusions are not warranted from the available data. REVIEWER'S CONCLUSIONS The limited number of identified trials together with their methodological weaknesses do not allow a reliable assessment of the possible role of sphincter exercises and biofeedback therapy in the management of people with faecal incontinence. There is a suggestions that some elements of biofeedback therapy and sphincter exercises may have a therapeutic effect, but this is not certain. Larger well-designed trials are needed to enable safe conclusions.

Abstract
BACKGROUND Complete rectal prolapse is a debilitating condition, which affects both the very young and the elderly and can cause faecal incontinence. The range of surgical methods available to correct the underlying anal sphincter or pelvic floor defects in complete rectal prolapse poses the question about the choice of the best operation. OBJECTIVES To determine the effects of surgery on the treatment of rectal prolapse in adults. The following specific issues have been addressed: I. Whether surgical intervention is better than no treatment; II. Whether an abdominal approach to surgery is better then a perineal approach; III. Whether one method for performing rectopexy is better than another; IV. Whether laparoscopic access is better than open access for surgery; V. Whether resection should be included in the procedure. SEARCH STRATEGY We searched the Cochrane Incontinence Group trials register, the Cochrane Colorectal Cancer Group trials register, the Cochrane Controlled Trials Register (Issue 2, 1999), Medline (up to March 1999), Embase (1998 up to January 1999), Sigle (1980 up to December 1996), Biosis (1998 up to March 1999), SCI (1998 up to March 1999), ISTP (1982 up to March 1999) and the reference lists of relevant articles. We hand searched the British Journal of Surgery 1995-8, and the Diseases of the Colon and Rectum 1995-8. We also searched the proceedings of the Association of Coloproctology, meeting 1999. Date of the most recent searches: March 1999. SELECTION CRITERIA All randomised or quasi-randomised trials of surgery in the management of rectal prolapse. DATA COLLECTION AND ANALYSIS Two reviewers independently selected studies from the literature, extracted data and assessed the methodological quality of eligible trials. The three primary outcome measures were number of patients with recurrent rectal prolapse, or residual mucosal prolapse or faecal incontinence. MAIN RESULTS Eight trials were included with a total of 264 participants. No trial included a group receiving no treatment, or anal encirclement, or Delormes procedure, or laparoscopic suture rectopexy, or laparoscopic resection rectopexy. One trial (20 participants) compared both perineal and abdominal resection rectopexy with pelvic floor repair; four trials (175 participants) compared different types of open rectopexy techniques; one trial (21 participants) compared laparoscopic with open mesh rectopexy; and two trials included comparisons between open resection rectopexy and rectopexy alone. In all comparisons data were few. There were no detectable differences in recurrent prolapse between abdominal and perineal approaches, although there was a suggestion that residual faecal incontinence was less common after abdominal surgery. There were no detectable differences between the methods used for fixation during rectopexy. Division, rather than preservation, of the lateral ligaments was associated with less recurrent prolapse but more post-operative constipation, although these findings were found in small numbers. There were too few data with which to compare laparoscopic with open surgery. Bowel resection during rectopexy was associated with lower rates of constipation, but again numbers were small. REVIEWER'S CONCLUSIONS The small number of relevant trials identified, and their small sample sizes together with other methodological weaknesses severely limit the usefulness of this review for guiding practice. It was impossible to identify or refute clinically important differences between the alternative surgical operations. Larger rigorous trials are needed to improve the evidence with which to define optimum surgical treatment.

Abstract
BACKGROUND Faecal incontinence is a particularly embarrassing and distressing condition with significant medical, social and economic implications. Electrical stimulation has been used with apparent success in the treatment of faecal incontinence. However, standards of treatment are still lacking and the magnitude of alleged benefits has yet to be established. OBJECTIVES To determine the effects of electrical stimulation for the treatment of faecal incontinence in adults. SEARCH STRATEGY We searched the Cochrane Incontinence Group trials register, the Cochrane Controlled Trials Register, Medline, Embase and reference lists of potentially eligible articles up to November 1999. Date of the most recent searches: November 1999. SELECTION CRITERIA All randomised or quasi-randomised trials evaluating electrical stimulation in adults with faecal incontinence. DATA COLLECTION AND ANALYSIS Three reviewers assessed the methodological quality of potentially eligible trials and two reviewers independently extracted data from the included trial. A wide range of outcome measures were considered. MAIN RESULTS Only one eligible trial with 40 participants was identified. It was a randomised trial, but it suffered from methodological drawbacks and did not follow up patients beyond the end of the trial period. Findings from this trial suggest that electrical stimulation with anal biofeedback and exercises provides more short-term benefits than vaginal biofeedback and exercises for women with obstetric-related faecal incontinence. No further conclusions could be drawn from the data available. REVIEWER'S CONCLUSIONS At present, there are insufficient data to allow reliable conclusions to be drawn on the effects of electrical stimulation in the management of faecal incontinence. There is a suggestion that electrical stimulation may have a therapeutic effect, but this is not certain. Larger, more generalisable trials are needed.

Abstract
BACKGROUND Incontinence is a distressing condition with significant medical, social and economic implications. People suffering from incontinence, who cannot be successfully cured, depend, almost exclusively, on the use of containment products to manage their symptoms. OBJECTIVES Many people with incontinence cannot be cured and so depend on symptomatic management. The objective was to assess the effects of different types of absorbent product for the containment of urinary and/or faecal incontinence. SEARCH STRATEGY We searched the Cochrane Incontinence Group trials register (March 1999), Embase (to January 1999), Cinahl (to January 1999), HealthSTAR (to January 1999) and the reference lists of relevant articles. We contacted investigators in the field to locate studies. Date of the most recent searches: March 1999. SELECTION CRITERIA Types of studies All randomised or quasi-randomised trials of absorbent products for the containment of urinary and/or faecal incontinence. Types of participants All adults with urinary and/or faecal incontinence were eligible. The intention was to subdivide participants by severity of underlying incontinence, level of mobility and gender, but this proved not to be feasible. Types of intervention Absorbent products (bodyworns, underpads, and different fabric types for disposable products), for any severity of incontinence. DATA COLLECTION AND ANALYSIS Trials were evaluated for subject relevance and methodological quality using a standard methodological quality assessment form. If applicable, data on relevant outcomes were then abstracted using a standardised data abstraction form. MAIN RESULTS Five studies with a total of 345 participants met the selection criteria. Two studies compared disposable with non-disposable bodyworns, one disposable with non-disposable underpads, two fluff pulp with superabsorbent polymers, and one bodyworns with underpads. Data presented on effects were available for few outcomes and were subject to potential bias. REVIEWER'S CONCLUSIONS The data were too few and of insufficient quality to provide a firm basis for practice. Disposable products may be more effective than non-disposable products in decreasing the incidence of skin problems and superabsorbent products may perform better than fluff pulp products. However, based on the available evidence, these conclusions can only be tentative.

Abstract
BACKGROUND Faecal incontinence is a debilitating problem with significant medical, social and economic implications. Treatment options include conservative, non-operative interventions (e.g. pelvic floor muscle training, biofeedback, drugs) and surgical procedures. Surgery is used in selected groupsof people when the structural and functional defects in the pelvic floor muscles or the anal sphincter complex can be corrected mechanically. OBJECTIVES To assess the effects of established surgical techniques for the treatment of faecal incontinence in adults who do not have rectal prolapse. Our aims were firstly to compare surgical management with non-surgical management and secondly, to compare the various surgical techniques. SEARCH STRATEGY We searched the Cochrane Incontinence Group trials register, the Cochrane Colorectal Cancer Group trials register, the Cochrane Controlled Trials Register (Issue 2, 1999), Medline (up to March 1999), Embase (1998 up to January 1999), Sigle (1980 up to December 1996), Biosis (1998 up to March 1999), SCI (1998 up to March 1999), ISTP (1982 up to March 1999) and the reference lists of relevant articles. We specifically hand searched the British Journal of Surgery from 1995 to 1998 and the Diseases of the Colon and Rectum from 1995 to 1998. We also perused the proceedings of the Association of Coloproctology, meeting 1999. Date of the most recent literature searches: March 1999. SELECTION CRITERIA All randomised or quasi-randomised trials of surgery in the management of adult faecal incontinence (other then surgery for rectal prolapse). DATA COLLECTION AND ANALYSIS Two reviewers independently selected studies from the literature, extracted data and assessed the methodological quality of eligible trials. The three primary outcome measures were: change or deterioration in incontinence, failure to achieve full continence, and the presence of faecal urgency. MAIN RESULTS Four trials were included with a total sample size of 110 participants. All trials excluded women with anal sphincter defects detected by endoanal ultrasound examination. No trial included a group managed non-surgically. Two trials (56 participants) compared three approaches to pelvic floor repair (anterior levatorplasty, postanal repair and their combination total pelvic floor repair). One trial (30 participants) evaluated adding plication of the anal sphincter to total pelvic floor repair. The fourth trial (24 participants) compared a neosphincter procedure with total pelvic floor repair. No differences in the primary outcomes were detected, but data were few and inconsistently reported. REVIEWER'S CONCLUSIONS The small number of relevant trials identified together with their small sample sizes and other methodological weaknesses severely limit the usefulness of this review for guiding practice. It was impossible to identify or refute clinically important differences between the alternative surgical procedures. Larger rigorous trials are needed.

Abstract
An episode of transient global memory loss was observed in a 27-year-old woman following a mild head injury in a car accident. Her clinical and neuropsychological profiles were indistinguishable from those of transient global amnesia (TGA). This paper argues that a cause-effect relationship may be postulated between head trauma and transient memory loss, perhaps as the result of a very stressful situation such as a car crash.

Abstract
The focus of this report is utilization behaviour (UB) conceived as part of the Environmental Dependency Syndrome following frontal damage. An historical sketch is provided on the many conceptualizations of the frontal lobe functions relevant to the understanding of UB. The detailed study of the neuropsychological picture presented by a patient (PG) with massive herpetic damage is then outlined. Emphasis is put on PG's prominent UB as well as on her several dissociations between impaired (as expected) and spared (non expected) cognitive abilities. Such dissociations are discussed with reference to the historical conceptualizations outlined above. The question is raised of whether a great inter-subjects variability of the topo-functional arrangements in the healthy frontal lobes could be the main cause of the variability of symptoms observed in patients with frontal lesions.

Abstract
Tonic alertness was investigated in Alzheimer patients and normal elderly subjects. Sensitivity and criterion shifts were investigated across 45 min of continuous testing using a high event rate test with very low target probability. Alzheimer patients showed a significant sensitivity decrement over time that was unrelated to dementia severity. These results suggest that tonic alertness is impaired by Alzheimer's disease even in its early stages.

Abstract
A new, short, neuropsychologically oriented test for dementia assessment--the Milan Overall Dementia Assessment (MODA)--is described. Age and education adjusted norms based on 217 healthy controls are given. A validation study on 312 outpatients suspected of dementia (121 with probable Alzheimer's disease) showed that the MODA differentiated patients with cognitive impairment from normal subjects more effectively than did the DSM III-R. The correlation between the MODA and the mini mental state examination was 0.63 in controls and 0.84 in patients with Alzheimer's dementia. The MODA test-retest reliability was 0.83. The test proved to be well suited to longitudinal studies.

Abstract
We report on a patient (PG) with a severe behavioural disorder following massive bilateral prefrontal damage due to herpetic encephalitis. The lesion involves also the mesial and polar regions of the temporal lobes; the frontal dorso-lateral cortices were relatively spared. The patient's inattentiveness and alternating impulsive and apathetic behaviour led to her social alienation. The only self-motivated activities we observed were those initiated to satisfy her enhanced urge to eat and play games. She did not react to surprise stimuli that consistently elicit a reaction of surprise in healthy people. She also presented "adynamic aphasia" associated with anomia and episodic amnesia. A striking feature of the syndrome was the patient's consistent "utilization behaviour". Her motor behaviour was marked by constant akathisia. She performed surprisingly well on intelligence, "frontal", and visuo-spatial tests. This non-demented patient exhibited a clear dissociation between her relatively spared cognitive abilities and grossly impaired behaviour. In the discussion we explore the extent to which a defect of the supervisory control may be held responsible for the inconsistencies in the patient's coping skill performances.
