It's a long-held belief that Modic changes (MC) occur only in adults, with advanced age, and are highly associated with pain and adverse outcomes. The following study addressed the epidemiology, risk factors and clinical relevance of MC in young paediatric patients. ⋯ Contrary to traditional dogma, robust evidence now exists noting that MCs and their types can develop in children. Our findings give credence to the "Juvenile" variant of MCs, whereby its implications throughout the lifespan need to be assessed. Juvenile MCs have prolonged symptoms and related to specific structural spine phenotypes.

Pathophysiological causes of low back pain (LBP) remain generally unclear, so focus has shifted to psychosocial features and central pain processing. Effects of attentional and affective manipulation on conditioned pain modulation and tonic pain perception were examined in 30 patients with recurrent LBP in 2 sessions, one with and one without clinical pain, and compared with healthy participants. Phasic cuff pressure on one leg, scored on a Numerical Rating Scale, was used for test stimuli, and contralateral tonic cuff pain rated on an electronic Visual Analogue Scale was the conditioning stimulus (CS). ⋯ Electronic Visual Analogue Scale scores of CS pain increased throughout all paradigms with CS (P < 0.05), except the CS&Positive paradigm, and greater facilitation was observed in the CS-Only paradigm than all others (P < 0.02), and lower facilitation was additionally observed in the CS&Positive paradigm compared with CS&Attention and CS&Negative paradigms (P < 0.01). Flanker effects and interruptive effects of CS pain on attention were observed consistent with prior findings, and affective manipulation produced less shift in valence among people with recurrent LBP than controls (P < 0.05). Attention and positive affect with CS pain evoked conditioned pain modulation, and all attentional or affective tasks, especially positive affect, reduced facilitation of CS pain.

The current qualitative study sought to obtain an in-depth understanding of how Arab-Americans conceptualize perceived injustice concerning their chronic low back pain (CLBP) by reflecting on the Injustice Experience Questionnaire (IEQ). Twelve Arab-American adults with CLBP were recruited from a metropolitan area in Alabama using a purposive sampling technique. Participants took part in individual, face-to-face, semi-structured interviews reflecting on each statement from the IEQ. ⋯ Additional exploration of the cultural appropriateness of the IEQ among individuals of Arab background is needed to further elaborate on the subject of faith and religious belief suggested by the current study. Perspective: Although the study findings largely reflected established injustice literature constructs, several emergent themes regarding pain-related injustice appraisal were influenced by the participants' culture and religious beliefs. These findings may indicate that specific psychotherapeutic approaches that have been proven effective among some groups may not function similarly in other populations.

Reliability of lumbar multifidus ultrasound assessment during the active straight leg raise test.
Previous evidence showed altered lumbar multifidus (LM) activation in populations with chronic nonspecific low back pain (LBP). We aimed to investigate the test-retest and inter-examiner reliability of ultrasound imaging (US) for assessing LM thickness at rest and activation during the active straight leg raise test (ASLR) and the association between thickness changes with clinical outcomes. ⋯ US is a reliable method to assess the LM thickness at rest and contracted during the ASLR in patients with LBP. The measurement at 3 s after maintaining ASLR, as well as the use of the mean of three measurements, has been shown to be the most reliable method for measuring LM muscle thickness during ASLR.

Low-value pharmaceutical care exists in general practice. However, the extent among Dutch GPs remains unknown. ⋯ The results show that the prevalence of low-value pharmaceutical GP care varies among these three clinical problems. Significant variation in inappropriate prescribing exists between different types of pharmaceutical care - and GP practices.
