BackgroundTreatment of complex regional pain syndrome type I (CRPS-I) is subject to discussion. The purpose of this study was to develop multidisciplinary guidelines for treatment of CRPS-I.MethodA multidisciplinary task force graded literature evaluating treatment effects for CRPS-I according to their strength of evidence, published between 1980 to June 2005. Treatment recommendations based on the literature findings were formulated and formally approved by all Dutch professional associations involved in CRPS-I treatment.ResultsFor pain treatment, the WHO analgesic ladder is advised with the exception of strong opioids. For neuropathic pain, anticonvulsants and tricyclic antidepressants may be considered. For inflammatory symptoms, free-radical scavengers (dimethylsulphoxide or acetylcysteine) are advised. To promote peripheral blood flow, vasodilatory medication may be considered. Percutaneous sympathetic blockades may be used to increase blood flow in case vasodilatory medication has insufficient effect. To decrease functional limitations, standardised physiotherapy and occupational therapy are advised. To prevent the occurrence of CRPS-I after wrist fractures, vitamin C is recommended. Adequate perioperative analgesia, limitation of operating time, limited use of tourniquet, and use of regional anaesthetic techniques are recommended for secondary prevention of CRPS-I.ConclusionsBased on the literature identified and the extent of evidence found for therapeutic interventions for CRPS-I, we conclude that further research is needed into each of the therapeutic modalities discussed in the guidelines.
The aim of this review was to identify systematically, criteria for trismus in head and neck cancer, the evidence for risk factors for trismus and the interventions to treat trismus. Three databases were searched (time period 1966 to June 2003) for the text "trismus" or "restricted mouth opening". Included in the review were clinical studies (> or = 10 patients). Two observers independently assessed the papers identified. In 12 studies nine different criteria for trismus were found without justifying these criteria. Radiotherapy (follow-up: 6-12 months) involving the structures of the temporomandibular joint and or pterygoid muscles reduces mouth opening with 18% (sd: 17%). Exercises using a therabite device or tongue blades increase mouth opening significantly (no follow-up), effect sizes (ES) 2.6 and 1.5 respectively. Microcurrent electrotherapy (follow-up 3 months) and pentoxifylline (no follow-up) increases mouth opening significantly (ES for both: 0.3).
Goals of work Critical weight loss (≥5% in 1 month or ≥10% in 6 months) is a common phenomenon in head and neck cancer patients. It is unknown which complaints are most strongly related to critical weight loss in head and neck cancer patients at the time of diagnosis. The aim of this explorative study was to assess the prevalence of critical weight loss and to analyze risk factors for critical weight loss in head and neck cancer patients before treatment. Materials and methods Critical weight loss and factors reducing dietary intake were assessed in 447 patients referred to an ear, nose and throat clinic at the time of diagnosis. Main results In total, data of 407 patients were analyzed. Critical weight loss was present in 19% of the patients. Patients with cancer in the hypopharynx, oropharynx/oral cavity and supraglottic larynx had the highest risk for critical weight loss. Loss of appetite, dysphagia/passage difficulties and loss of taste/aversion were significantly (p<0.05) associated with critical weight loss. Conclusions Already before treatment, critical weight loss is a considerable problem in head and neck cancer patients. Critical weight loss is frequently observed in patients with cancer in the hypopharynx, oropharynx/oral cavity and supraglottic larynx.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
