Fibromyalgia. Chakrabarty S, Zoorob R. Am Fam Physician. 2007 Jul 15;76(2):247-54. Fibromyalgia is an idiopathic, chronic, nonarticular pain syndrome with generalized tender points. It is a multisystem disease characterized by sleep disturbance, fatigue, headache, morning stiffness, paresthesias, and anxiety. Nearly 2 percent of the general population in the United States suffers from fibromyalgia, with females of middle age being at increased risk. The diagnosis is primarily based on the presence of widespread pain for a period of at least three months and the presence of 11 tender points among 18 specific anatomic sites. There are certain comorbid conditions that overlap with, and also may be confused with, fibromyalgia. Recently there has been improved recognition and understanding of fibromyalgia. Although there are no guidelines for treatment, there is evidence that a multidimensional approach with patient education, cognitive behavior therapy, exercise, physical therapy, and pharmacologic therapy can be effective.
Efficacy of Cognitive-Behavioral Therapies in Fibromyalgia Syndrome - A Systematic Review and Metaanalysis of Randomized Controlled Trials. Bernardy K, Füber N, Köllner V, Häuser W.J Rheumatol. 2010 Aug 3. [Epub ahead of print] OBJECTIVE: We performed the first systematic review with metaanalysis of the efficacy of cognitive-behavioral therapies (CBT) in fibromyalgia syndrome (FM). METHODS: We screened Cochrane Library, Medline, PsychINFO, and Scopus (through June 2009) and the reference sections of original studies and systematic reviews for CBT in FM. Randomized controlled trials (RCT) comparing CBT to controls were analyzed. Primary outcomes were pain, sleep, fatigue, and health-related quality of life (HRQOL). Secondary outcomes were depressed mood, self-efficacy pain, and healthcare-seeking behavior. Effects were summarized using standardized mean differences (SMD).(…)

Een voorbeeld Internet-treatment for (reducing) alcohol drinking/ alcohol related disorders • Alcohol drinking • Internet intervention • Randomized controlled trials
Stap 1: concepten zoekstrategie • Alcohol drinking • Internet therapies • randomized controlled trials
Hoe kom je aan zoektermen? • pilot-searches! • selecteer relevante titels • bekijk indexering (MeSH) Start “omgekeerd”:begin met wat je al hebt
Voorbeeld Medical Subject Heading All MeSH Categories Persons Category Persons Age Groups Adult Aged Aged, 80 and over Frail Elderly
Stap 3: Zoektermen combineren Boolean operators AND OR NOT

Stap 4: methodologische filters • Gevalideerde “zoekstrings” gericht op vinden van bepaalde onderzoeksdesigns(bv gerandomiseerd of observationeel onderzoek) • Bv PubMed filter Therapy/narrow (Haynes RB e.a.)
Stap 5: Evalueren & verbeteren Dit is een cruciale stap bij het ontwikkelen van een goede strategie
Evalueren & verbeteren zoekresultaat behapbaar? worden alle (bekende) relevante titels gevonden met de zoekstrategie? Leveren checks (referentielijsten, related citations) géén extra relevante titels meer op? “Nee”? zoekstrategie verbeteren!
