Glucocorticoid treatment in patients with complex regional pain syndrome: A systematic review

Background and objective The pathophysiology of complex regional pain syndrome (CRPS) is multifactorial, with an exaggerated inflammatory response being the most prominent. Treatment for CRPS is carried out according to the presenting pathophysiological mechanism. Anti-inflammatory treatment with glucocorticoids is therefore an option. The aim of this study was to systematically review the efficacy of glucocorticoids in CRPS. Databases and data treatment Embase, Medline, Web of Science and Google Scholar were systematically searched for articles focusing on glucocorticoid treatment and CRPS. Screening based on title and abstract was followed by full-text reading (including reference lists) to determine the final set of relevant articles. Bias was assessed using the revised Cochrane risk-of-bias-tool for randomized trials (Rob2). Results Forty-one studies were included, which reported on 1208 CRPS patients. A wide variety of glucocorticoid administration strategies were applied, with oral being the most frequently chosen. Additionally, researchers found great heterogeneity in outcome parameters, including clinical symptoms, pain relief and range of motion. The use of glucocorticoids caused an improvement of parameters in all but two studies. In particular, improvement in pain relief and range of motion were reported. Using glucocorticoids in CRPS of longer duration (i.e. more than 3 months) appears to be less effective. Conclusion Based on the present review, there is evidence to support glucocorticoid treatment in CRPS. However, the ideal administration route and dose remain unclear. We therefore recommend future research via an intervention study, as well as studies on the aetiological mechanisms and corresponding optimal treatment because CRPS pathogenesis is only partially understood. Significance Several studies point towards CRPS being an inflammatory response after tissue or nerve damage, with higher levels of pro-inflammatory cytokines in serum, plasma, cerebrospinal fluid and artificial skin blisters. Inflammation provides a possible role for glucocorticoids in treating CRPS. This systematic review provides a structured overview of glucocorticoid treatment in patients with CRPS. Improvement in pain and range of motion is shown. Systematic review registration number: PROSPERO-CRD42020144671

Primary Management of Operable Locally Advanced Oral Cavity Squamous Cell Carcinoma: Current Concepts and Strategies

Introduction: Locally advanced oral cavity carcinoma (LAOCSCC) is primarily treated with surgery followed by radiotherapy with or without chemotherapy. Methods: A review of literature using PubMED was performed for studies reporting the management of LAOCSCC. Based on the reviewed literature and opinions of experts in the field, recommendations were made. Results: Studies have shown that outcomes following resection of T4a and infranotch (inferior to mandibular notch) T4b are comparable. We discuss the concept of compartmental resection of LAOCSCC and issues concerning the management of the neck. Further, patients who refuse or are unable to undergo surgery can be treated with chemoradiotherapy with uncertain outcomes. The role of neoadjuvant chemotherapy has shown promise for organ (mandibular) preservation in a select subset of patients. Conclusion: The management strategy for LAOCSCC should be determined in a multidisciplinary setting with emphasis on tumor control, functional preservation, and quality of life of the patient

Cost-utility of an eHealth application ‘Oncokompas’ that supports cancer survivors in self-management: results of a randomised controlled trial

Purpose: The eHealth self-management application ‘Oncokompas’ was developed to support cancer survivors in monitoring health-related quality of life (HRQOL) and symptoms, and obtaining personalized feedback and options for supportive care. The aim of this study was to assess the cost-utility of Oncokompas compared with care as usual (CAU) among cancer survivors. Methods: Survivors were randomly allocated to the intervention or control group. Direct (non-)medical, indirect non-medical costs, and HRQOL were measured at 3- and 6-month follow-up, using iMTA Medical Consumption and Productivity Costs and the EuroQol-5D questionnaires. Mean cumulative costs and quality-adjusted life-years (QALYs) were compared between both groups. Results: In total, 625 survivors were randomized into intervention (n = 320) or control group (n = 305). Base case analysis showed that incremental costs from a societal perspective were − €163 (95% CI, − 665 to 326), and incremental QALYs were 0.0017 (95% CI, − 0.0121 to 0.0155) in the intervention group compared with those in the control group. The probability that, c
