Prevalence and characterization of breakthrough pain in patients with cancer in Spain: the CARPE-DIO study.

We aimed to evaluate the prevalence, characteristics and impact of breakthrough pain (BTP) in patients with cancer attending the main specialties involved in the diagnosis and management of BTP in Spain using a multicenter, observational, cross-sectional, multidisciplinary study. Investigators had to record all patients seen at the clinic during 1 month, determine whether the patients had cancer pain, and apply the Davies algorithm to ascertain whether the patients were suffering from BTP. Of the 3,765 patients with cancer, 1,117 (30%) had cancer-related pain, and of these patients, 539 had BTP (48%, 95%CI:45-51).

Complex Regional Pain Syndrome in Children: a Multidisciplinary Approach and Invasive Techniques for the Management of Nonresponders.

Complex regional pain syndrome (CRPS) is multifactorial condition with complex pathogenesis characterized by spontaneous or stimulus-induced pain that is disproportionate to the inciting event. It is also commonly accompanied by a myriad of autonomic and motor disturbances in highly variable combinations. This condition has been underreported in children until recently.

Management of pain secondary to temporomandibular joint syndrome with peripheral nerve stimulation.

Background: Temporomandibular joint syndrome, or Costen syndrome, is a clinically diagnosed disorder whose most common symptoms include joint pain and clicking, difficulty opening the mouth, and temporomandibular joint discomfort. The temporomandibular joint (TMJ) is supplied by the auriculotemporal nerve, a collateral branch of the mandibular nerve (the V3 branch of the trigeminal nerve).

Objectives: The aim of this study is to assess the effectiveness and safety of permanent peripheral nerve stimulation to relieve TMJ pain.
