Of the 3 most commonly encountered interventional procedures for chronic headaches, peripheral nerve surgery via decompression of involved peripheral nerves has been the best-studied modality in terms of total number of studies, level of evidence of published studies, and length of follow-up. Reported success rates for nerve decompression or excision tend to be higher than those for peripheral nerve stimulation or for RF, although poor study quantity and quality prohibit an accurate comparative analysis. Of the 3 procedures, peripheral nerve stimulator implantation was associated with the greatest number of complications. Although peripheral nerve surgery seems to be the interventional treatment modality that is currently best supported by the literature, better controlled and normalized high-quality studies will help to better define the specific roles for each type of intervention.

The novel coronavirus disease (COVID-19) pandemic has significantly impacted the field of rheumatology, in both the delivery of clinical care and didactic education for our trainees. These changes have generated significant strain for program directors and clinical educators who have had to leverage technology and develop new systems to ensure continued trainee education and assessment. We aim to outline the impacts on formal education programs presented by these unprecedented disruptions, describe the development and deployment of online teaching, reflect on the challenges and opportunities for technology-enabled learning and use of social media for education, and give some international perspectives on impacts on postgraduate rheumatology training outside the USA. With the rapid dissolution of barriers in place during the pre-COVID-19 era, we have the opportunity to assess the efficacy of new methods of care and further integrate technology into teaching and assessment. We propose that a hybrid in-person and technology-enabled learning approach, so-called blended learning, is likely to remain the most desirable future model for supporting trainee learning.
