Randomized Controlled Trial
Referred sensation location can be altered by a strong heterotopic nociceptive stimulus: Implications for clinical pain conditions.
Referred sensations (RS) are a common clinical phenomenon in patients with musculoskeletal pain; however, the underlying mechanisms of RS and implications for diagnosis and management are poorly understood. The location of referral seems to have a preferred site, but studies have suggested it can be redirected to a site of previous injury and pain. However, it is not known if the same phenomenon can occur for a much shorter-lasting painful stimulus in the trigeminal system. ⋯ However, the RS location was displaced on average 1.2 cm between the baseline and postinfusion assessments for the hypertonic saline infusion, which was significantly increased when compared with the isotonic saline infusion which was on average 0.4 cm. These novel findings indicate the potential to modify the location of RS in the trigeminal system following a relatively brief noxious input. Clinicians need to be aware of the possible rerouting of RS in patients with complex orofacial pain.

The increasing demand for pain management and limited resources available highlight the need to measure treatment effectiveness. We analysed data collected at 75 specialist persistent pain services located in Australia and New Zealand to calculate the overall treatment outcome for patients receiving care during 2014 to 2020. Sociodemographic and clinical information was provided for 23,915 patients, along with patient-reported measures assessing pain, pain interference, depression, anxiety, stress, pain catastrophizing, and pain self-efficacy. ⋯ Multivariable logistic regression identified those factors associated with the different groups. In particular, factors most predictive of a poor (group 4) vs good outcome (group 1) were unemployment (due to pain or other reasons), requiring an interpreter, widespread pain, pain of longer duration, and attributing the pain to an injury at work. The results may allow identification of those most likely to benefit from the services currently provided and inform development of alternative or enhanced services for those at risk of a poor outcome.

'My back is fit for movement': A qualitative study alongside a randomised controlled trial for chronic low back pain.
A new wave of treatments has emerged to target nervous system alterations and maladaptive conceptualizations about pain for chronic low back pain. The acceptability of these treatments is still uncertain. We conducted a qualitative study alongside a randomized controlled trial to identify perceptions of facilitators or barriers to participation in a non-pharmacological intervention that resulted in clinically meaningful reductions across 12 months for disability compared to a sham intervention. ⋯ These findings suggest the importance of psychoeducation and behavior change techniques to create a positive attitude towards movement and increase the perception of pain control; systematic approaches to monitor and target misconceptions about the interventions during treatment; and psychoeducation and behavior change techniques to maintain the improvements after the cessation of formal care. PERSPECTIVE: This article presents the experiences of people with chronic low back pain participating in a new non-pharmacological brain-targeted treatment that includes face-to-face and self-directed approaches. The facilitators and barriers of the interventions could potentially inform adaptations and optimization of treatments designed to target the brain to treat chronic low back pain.

Thrombotic microangiopathy is a pathological condition comprised of microvascular thrombosis involving any body organ leading to thrombocytopenia, coombs-negative hemolytic anemia, and end-organ damage. The clinical presentation of the case shows typical hemolytic uremic syndrome, however, lab reports show atypical hemolytic uremic syndrome (low C3). Pain abdomen and loose stool with some signs of dehydration were initial presentations. Early initiation of renal replacement therapy and management of dehydration was done. Simple diarrhea can also manifest as acute kidney injury with the hemolytic uremic syndrome. Hence we should keep hemolytic uremic syndrome as the differential diagnosis of diarrhea. Irrespective of lab parameters, early management in line with the typical hemolytic uremic syndrome should be done for better outcomes. ⋯ anemia; case reports; dehydration; renal replacement therapy.

Pain management for patients with dementia is challenging because many experience pain while being unable to communicate their pain. The aim of this study was to describe pain, pain management, and to perform a thorough clinical examination of chronic pain conditions among patients with dementia. Residents (n = 498) from 12 nursing homes were assessed for dementia (Clinical Dementia Rating scale [CDR]) and for pain with the Mobilization-Observation-Behavior-Intensity-Dementia-2 (MOBID-2) assessment form. ⋯ Chronic widespread pain was the most prevalent (14.5%) followed by nonspecific pain from the back (13.4%), whereas the most prevalent chronic secondary pain conditions were chronic pain caused by osteoarthritis (15.4%) and stroke (8.0%). One-fourth received opioids, which was significantly associated with severe pain ( P < 0.001) compared with moderate pain, although no significant association was found between opioid use and the type of pain condition. Although knowledge of the severity and specific types of pain conditions is recommended to direct the choice of treatment, these areas are not sufficiently explored in the nursing home populations with dementia and may hinder a better treatment of pain in this population.
