Effectiveness of complementary and self-help treatments for depression in children and adolescents

OBJECTIVE: To review the evidence for the effectiveness of complementary and self-help treatments for depression in children and adolescents. DATA SOURCES: Systematic literature search using PubMed, PsycINFO and the Cochrane Library for 131 treatments up to February 2006. STUDY SELECTION: There were 13 treatments that had been evaluated in intervention studies. DATA EXTRACTION: Studies on each treatment were reviewed by one author and checked by a second. A consensus was reached for level of evidence. DATA SYNTHESIS: Relevant evidence was available for glutamine, S-adenosylmethionine, St John's wort, vitamin C, omega-3 fatty acids, light therapy, massage, art therapy, bibliotherapy, distraction techniques, exercise, relaxation therapy and sleep deprivation. However, the evidence was limited and generally of poor quality. The only treatment with reasonable supporting evidence was light therapy for winter depression. CONCLUSIONS: Given that antidepressant medication is not recommended as a first line treatment for children and adolescents with mild to moderate depression, and that the effects of psychological treatments are modest, there is a pressing need to extend the range of treatments available for this age group.     

Effectiveness of complementary and self-help treatments for anxiety in children and adolescents

OBJECTIVE: To review the evidence for the effectiveness of complementary and self-help treatments for anxiety disorders and situational anxiety in children and adolescents. DATA SOURCES: Systematic literature search using PubMed, PsycINFO and the Cochrane Library for 111 treatments up to February 2006. STUDY SELECTION: There were 11 treatments for which intervention studies had been undertaken and reported. DATA EXTRACTION: Studies on each treatment were reviewed by one author and checked by a second. A consensus was reached for level of evidence. DATA SYNTHESIS: Relevant evidence was available for bibliotherapy, dance and movement therapy, distraction techniques, humour, massage, melatonin, relaxation training, autogenic training, avoiding marijuana, a mineral-vitamin supplement (EMPower +) and music therapy. Findings from case-control studies, individual cohort studies or low quality randomised controlled trials indicated that several treatments may have potential to reduce anxiety, including bibliotherapy, massage, melatonin, and relaxation training. CONCLUSIONS: Although some complementary and self-help treatments might be useful for children and adolescents with anxiety, they need to be tested adequately through randomised controlled trials before they could be recommended.     

Australian school-based prevention and early intervention programs for anxiety and depression: a systematic review

OBJECTIVE: To establish the nature and efficacy of Australian school-based prevention and early intervention programs for anxiety and depression. DATA SOURCES: Cochrane, PsychInfo and PubMed databases, and the Primary Mental Health Care Australian Resource Centre database, were searched in June 2006. Additional materials were obtained from program websites, reference lists and authors. STUDY SELECTION: Programs that were developed in Australia or trialled in Australia and addressed anxiety, depression, or resilience were included. DATA SYNTHESIS: 24 efficacy or effectiveness trials of 9 intervention programs were identified. Most were based on cognitive behaviour therapy, interpersonal therapy or psychoeducation. Six were universal interventions, two were indicated programs and one was a treatment program. Most were associated with short-term improvements or symptom reduction at follow-up. CONCLUSIONS: A number of schools programs produce positive outcomes. However, even well established programs require further evaluation to establish readiness for broad dissemination as outlined in the standards of the Society for Prevention Research.     

Pharmacologic management of refractory depression.

OBJECTIVE: To review published clinical trials of the pharmacologic management of refractory depression. DATA SOURCES: MEDLINE was searched for relevant articles published from 1983 to 1990. The bibliographies of review articles were searched for additional references. Studies of nonpharmacologic treatments, such as electroconvulsive therapy, were not included. STUDY SELECTION: Eleven studies were found that did not contain obvious digressions from several methodologic assessment criteria (adapted from the McMaster guidelines for the evaluation of clinical trials). Further scrutiny by a nonblind reviewer resulted in the selection of four reports that were considered acceptable. An assessment by a second reviewer, blind as to author, results and journal name, confirmed this judgement. DATA EXTRACTION: Data describing response to the treatments were extracted by a single (nonblind) reviewer. Post-hoc power estimates and 95% confidence intervals were calculated whenever possible. DATA SYNTHESIS: The efficacy of augmenting an antidepressant regimen with lithium carbonate, triiodothyronine or reserpine was not supported by findings from the clinical trials reviewed. However, many trials with negative results lacked adequate statistical power to exclude the possibility of the drug's efficacy. The use of a monoamine oxidase inhibitor was supported by the one study that met the review's methodologic criteria. However, this study was not conducted under double-blind conditions. CONCLUSION: The generally recommended strategies for the pharmacologic treatment of refractory depression are not supported by methodologically sound studies.     

A comparison of results of meta-analyses of randomized control trials and recommendations of clinical experts. Treatments for myocardial infarction.

OBJECTIVE--To examine the temporal relationship between accumulating data from randomized control trials of treatments for myocardial infarction and the recommendations of clinical experts writing review articles and textbook chapters. DATA SOURCES--(1) MEDLINE search from 1966 to present; search terms used were myocardial infarction, clinical trials, multicenter studies, double-blind method, meta-analysis, and the text word "random:"; (2) references from pertinent articles and books; and (3) all editions of English-language general medical texts and manuals and review articles on treatment of myocardial infarction. STUDY SELECTION--Randomized control trials of therapies for reducing the risk of total mortality in myocardial infarction (acute and secondary prevention). Review articles and textbook chapters dealing with the general clinical management of patients with myocardial infarction. DATA EXTRACTION--Two authors read the material and recorded the results; disagreements were resolved by conference. DATA SYNTHESIS--We used the technique of cumulative meta-analysis (performing a new meta-analysis when the results of a new clinical trial are published) and compared the results with the recommendations of the experts for various treatments for myocardial infarction. Discrepancies were detected between the meta-analytic patterns of effectiveness in the randomized trials and the recommendations of reviewers. Review articles often failed to mention important advances or exhibited delays in recommending effective preventive measures. In some cases, treatments that have no effect on mortality or are potentially harmful continued to be recommended by several clinical experts. CONCLUSIONS--Finding and analyzing all therapeutic trials in a given field has become such a difficult and specialized task that the clinical experts called on to summarize the evidence in a timely fashion need access to better databases and new statistical techniques to assist them in this important task.     

Pelvic inflammatory disease. Key treatment issues and options.

OBJECTIVE.--To examine available data regarding optimal antimicrobial therapy for pelvic inflammatory disease (PID) and to address selected treatment issues confronting clinicians caring for women with PID. DATA SOURCES.--Studies evaluated to help establish the Centers for Disease Control's 1989 Sexually Transmitted Diseases Treatment Guidelines and other reports published since 1985. A MEDLINE search of English-language literature was conducted using the indexing terms "pelvic inflammatory disease" or "pelvic infections" or "salpingitis" and "treatment". In addition, abstracts and bibliographies of articles and books were reviewed. STUDY SELECTION.--Studies were selected for detailed review if they evaluated the effectiveness of an antimicrobial regimen for treatment of PID. DATA EXTRACTION.--All studies were evaluated to determine the numbers of women treated and the percentage with clinical or microbiologic evidence of cure. DATA SYNTHESIS.--A variety of combination antimicrobial regimens are highly effective in providing clinical and microbiologic evidence of cure; few data are available to assess optimal therapy for prevention of late sequelae. Because PID is polymicrobial in cause, recommended antimicrobial regimens are broad-spectrum in coverage. CONCLUSIONS.--No single agent that provides sufficient coverage is currently available. Several combination regimens appear highly effective clinically even among women with tubo-ovarian abscess formation. Uncertainties regarding the effectiveness of antimicrobial therapy for prevention of late sequelae complicate decisions regarding the choice among regimens and the appropriateness of ambulatory treatment of women with PID. Pending better data, hospitalization should be strongly considered, where feasible, particularly for those women with PID desiring further childbearing. Sex partners of all women with PID should be treated.     

Maggot debridement therapy in chronic wound care.

OBJECTIVE: To review the current evidence on the mechanism of actions and clinical applications of maggot debridement therapy. DATA SOURCES: Literature search of PubMed and Medline was performed up to January 2007. STUDY SELECTION: Original and major review articles related to maggot debridement therapy were reviewed. Key words used in the literature search were 'maggot debridement therapy', 'wound healing', and 'chronic wound management'. DATA EXTRACTION: All relevant English and Chinese articles. DATA SYNTHESIS: The mechanism of such maggot therapy was shown to be due to the debridement, disinfection, and wound healing enhancement actions of maggot excretions/secretions. The efficacy of maggot debridement therapy in chronic wound management has been demonstrated in chronic venous ulcers, pressure ulcers, and diabetic ulcers. There is also a new delivery system for the excretions/secretions, which has been shown to be as effective as using live maggots. CONCLUSIONS: Maggot debridement therapy has been shown to be a safe and effective means of chronic wound management. However, there are a number of limitations when considering its local applicability. Future development of the delivery system may help to overcome some of these limitations and improve its acceptability.     

Interventions for the treatment and management of chronic fatigue syndrome: a systematic review

CONTEXT: A variety of interventions have been used in the treatment and management of chronic fatigue syndrome (CFS). Currently, debate exists among health care professionals and patients about appropriate strategies for management. OBJECTIVE: To assess the effectiveness of all interventions that have been evaluated for use in the treatment or management of CFS in adults or children. DATA SOURCES: Nineteen specialist databases were searched from inception to either January or July 2000 for published or unpublished studies in any language. The search was updated through October 2000 using PubMed. Other sources included scanning citations, Internet searching, contacting experts, and online requests for articles. STUDY SELECTION: Controlled trials (randomized or nonrandomized) that evaluated interventions in patients diagnosed as having CFS according to any criteria were included. Study inclusion was assessed independently by 2 reviewers. Of 350 studies initially identified, 44 met inclusion criteria, including 36 randomized controlled trials and 8 controlled trials. DATA EXTRACTION: Data extraction was conducted by 1 reviewer and checked by a second. Validity assessment was carried out by 2 reviewers with disagreements resolved by consensus. A qualitative synthesis was carried out and studies were grouped according to type of intervention and outcomes assessed. DATA SYNTHESIS: The number of participants included in each trial ranged from 12 to 326, with a total of 2801 participants included in the 44 trials combined. Across the studies, 38 different outcomes were evaluated using about 130 different scales or types of measurement. Studies were grouped into 6 different categories. In the behavioral category, graded exercise therapy and cognitive behavioral therapy showed positive results and also scored highly on the validity assessment. In the immunological category, both immunoglobulin and hydrocortisone showed some limited effects but, overall, the evidence was inconclusive. There was insufficient evidence about effectiveness in the other 4 categories (pharmacological, supplements, complementary/alternative, and other interventions). CONCLUSIONS: Overall, the interventions demonstrated mixed results in terms of effectiveness. All conclusions about effectiveness should be considered together with the methodological inadequacies of the studies. Interventions which have shown promising results include cognitive behavioral therapy and graded exercise therapy. Further research into these and other treatments is required using standardized outcome measures.     

Efficacy of treatments for posttraumatic stress disorder. An empirical review.

OBJECTIVE--The purpose of this article is to review the empirical evidence for the efficacy of a range of treatments for posttraumatic stress disorder (PTSD). Reviewed studies focused on rape victims, combat veterans, the tragically bereaved, torture victims, accident victims, of physical assault, and child abuse victims. DATA SOURCES--Peer-reviewed journals (Psych-Info, MEDLINE), book chapters (PILOTS database), active investigators, abstracts from the 1990 and 1991 International Society for Traumatic Stress Studies. STUDY SELECTION--We identified 255 English-language reports of treatment for PTSD. We restricted our focus to randomized, clinical trials that included a systematic assessment of PTSD using DSM-III or DSM-III-R criteria (N = 11). DATA EXTRACTION--Studies were assessed according to methodological strength: random assignment to the treatment of interest, and either an alternative treatment or control group; sample selection; and inclusion of statistical tests of significance. DATA SYNTHESIS--Drug studies show a modest but clinically meaningful effect on PTSD. Stronger effects were found for behavioral techniques involving direct therapeutic exposure, particularly in terms of reducing PTSD intrusive symptoms. However, severe complications have also been reported from the use of these techniques in patients suffering from other psychiatric disorders. Studies of cognitive therapy, psychodynamic therapy, and hypnosis suggest that these approaches may also hold promise. However, further research is needed before any of these approaches can be pronounced effective as lasting treatment of PTSD. CONCLUSIONS--Further studies should specifically address combined treatment approaches, optimal treatment length and timing, effects of comorbidity, and unstudied traumatized populations.     

Why don't we use vitamin E in dermatology?

OBJECTIVE: To review the possible uses of topical and systemic tocopherols as therapy for skin conditions in light of the widespread use of vitamin E by patients. DATA SOURCES: Index Medicus was searched for articles published from 1922 (when vitamin E was discovered) to 1966 (the beginning of MEDLINE). MEDLINE was searched for articles in English and French on vitamin E or tocopherol in relation to dermatology. Additional original articles were identified from the reference lists of the review articles. STUDY SELECTION: Only well-designed controlled studies were accepted; anecdotes and open studies are cited for completeness and as direction for future research. DATA SYNTHESIS: There was some weak or conflicting evidence that vitamin E is of value in yellow nail syndrome, vibration disease, epidermolysis bullosa, cancer prevention, claudication, cutaneous ulcers, and collagen synthesis and wound healing. It was of no use in atopic dermatitis, dermatitis herpetiformis, psoriasis, subcorneal pustular dermatosis, porphyrias and skin damage induced by ultraviolet light. CONCLUSIONS: After 44 years of research there is still scant proof of vitamin E's effectiveness in treating certain dermatologic conditions. Further research in well-designed controlled trials is needed to clarify vitamin E's role.
