The patient acceptable symptom state (PAccSS) is the value beyond which patients consider themselves well. Our aim was to determine the PAccSS of chronic pain in Moroccan outpatients suffering from chronic rheumatic diseases and to identify contributors to PAccSS. ⋯ Half of patients were satisfied of their disease state, while the PAccSS threshold of pain was unexpectedly high. This could be explained by an overestimation of the pain intensity or a Moroccan patients' high tolerance to pain. The main protective factors that contribute to achieving the PAccSS were high educational level, high socioeconomic status, higher functional status, and shorter term disease duration.

Potential peripheral sources of pain from subcutaneous tissue can require invasive evocative tests for their localization and assessment. Here, we describe studies whose ultimate goal is development of a noninvasive evocative test for subcutaneous, painful tissue. ⋯ Successful stimulation of the neuroma by intense focused ultrasound required colocalization of the neuroma and intense focused ultrasound supporting our hypothesis.

BACKGROUND.: The sacroiliac joint (SIJ) complex has been identified as a common source of chronic low back pain. Radiofrequency (RF) neurotomy has been investigated in recent years as a minimally invasive treatment option for SIJ-mediated low back pain. A number of RF neurotomy methodologies have been investigated, including the use of cooled RF. ⋯ RESULTS.: When stratified by time to final follow-up (4-6, 6-12, and >12 months, respectively): 86%, 71%, and 48% of subjects experienced ≥50% reduction in VAS pain scores, 96%, 93%, and 85% reported their quality of life as much improved or improved, and 100%, 62%, and 67% of opioid users stopped or decreased use of opioids. CONCLUSIONS.: The current results show promising, durable improvements in pain, quality of life, and medication usage in a large European study population, with benefits persisting in some subjects at 20 months after treatment. These results are consistent with previous study findings on the use of cooled RF to treat SIJ-mediated low back pain.

Chronic pain is a public health concern, and in the last decade, there has been a dramatic increase in the use and abuse of prescription opioids for chronic non-cancer pain. ⋯ The model presented is a patient-centered, efficient, and cost-effective approach to the management of chronic pain.

To translate the original English version of the Profile of Chronic Pain: Screen (PCP:S) into Brazilian Portuguese and examine basic psychometric properties of the translated version. We investigated ceiling and floor effects, internal consistency, factor structure, convergent validity, and the ability of the Brazilian PCP:S (B-PCP:S) to discriminate persons with pain who were either employed or not working, or in treatment or not in treatment. ⋯ This B-PCP:S version was found to be a reliable instrument, with basic evidence of validity for the evaluation of pain severity, interference, and emotional burden in Brazilian Portuguese adults. The profile of B-PCP:S scores was similar to that observed in the original version.
