Migration health research in Norway: a scoping review.

Aims: To provide an overview of published research on migration and health conducted in Norway and identify gaps in the research field. Methods: Applying a scoping review methodology, we searched Medline for articles on migration health in Norway published between 2008 and 2020, and assessed them according to research topic, methodology, user-involvement and characteristics of the populations studied (country or area of origin, type of migrant/immigrant status). Results: Of the 707 articles retrieved, 303 met the inclusion criteria. Most studies (77%) were within the clinical disciplines reproductive health, mental health, infectious diseases and cardiovascular diseases, or on socio-cultural aspects and the use of healthcare services. One third of the papers (36%) pulled participants from various geographic backgrounds together or did not specify the geographic background. Among those who did so, participants were mostly from The Middle East, South and Southeast Asia and sub-Saharan Africa. Only 14% of the articles specified the type of migrant/immigrant status and those included refugees, asylum seekers and undocumented migrants. A total of 80% of the papers used quantitative methods, of which 15 described an intervention; 15 papers (5%) described different types of user-involvement. Conclusions: Our findings suggest gaps in research related to migrant subgroups, such as those from Eastern-Europe and labour and family reunification migrants. Future studies should further investigate the self-identified health needs of different migrant groups, and might also benefit from a methodological shift towards more intervention studies and participatory approaches.

Spinal cord stimulation in severe cases of complex regional pain syndrome: A retrospective cohort study with long-term follow-up.

BACKGROUND: Complex regional pain syndrome (CRPS) is a debilitating pain condition often resistant to standard treatment modalities. In these cases, spinal cord stimulation (SCS) can be an option, but the effect on CRPS remains disputed. We aimed to assess the long-term effect of SCS on CRPS. METHODS: We retrospectively analysed 51 CRPS patients implanted with an SCS system at the University Hospitals in Aarhus or Odense, Denmark, with a median follow-up time of 4.4 years. Primary outcomes were pain intensity on a numeric rating scale (NRS) and the Patients' Global Impression of Change (PGIC). Secondary outcomes were patient satisfaction, work status, consumption of pain medication, the Major Depression Inventory (MDI), Pain Catastrophizing Scale (PCS) and quality of life (QoL) measured using the Short-Form Health Survey (SF-36). For each outcome measure, baseline data were compared to the latest collected data point. RESULTS: A significant pain relief was found with a mean reduction in NRS score of 2.4 (95% CI: 1.7-3.0, p < 0.0001). 68.8% reported 'much improved' or 'very much improved' on the PGIC scale. 87.5% would choose SCS again for the same outcome. A significant beneficial impact was found on MDI score, PCS, SF-36 summary scores and consumption of tricyclic antidepressants, antiepileptic drugs and opioids. No statistical effect was found on work status. CONCLUSION: Pain intensity, depression, pain catastrophizing, pain medication use and QoL were significantly improved after SCS implantation, with high patient satisfaction rates in CRPS patients. This study supports the continued use of SCS in the treatment of severe CRPS. SIGNIFICANCE: This study presents detailed data from a large, well-characterized cohort of Danish CRPS patients treated with SCS, analyzing several outcome measures. The results serve to document SCS as an effective treatment for severe CRPS and expands the cumulative level of evidence in favor of its use. Additionally, analysis of preoperative patient characteristics suggests that SCS treatment should not be withheld in patients with a high degree of psychological distress or high consumption of analgesics.

Multiple Limb Involvement in a Severe Case of Complex Regional Pain Syndrome Treated With Spinal Cord Stimulation: A Case Report.

Complex regional pain syndrome (CRPS) can be a debilitating, persistent, and treatment-resistant pain condition. This report presents a case of severe CRPS affecting multiple limbs, resistant to standard treatment modalities. Treatment with spinal cord stimulation (SCS) had an initial good effect. Nevertheless, the CRPS continued to progress, eventually affecting all 4 extremities. A lead fracture resulted in a rapidly developing recurrence of CRPS in the patient's arm, necessitating amputation. SCS may be an effective modality for treatment of severe CRPS. However, mechanical problems should always be considered when an SCS-implanted patient experiences rapid symptom progression or abrupt cessation of stimulation.
