Comparative Study
The COMFORT-behavior scale is useful to assess pain and distress in 0- to 3-year-old children with Down syndrome.
Many pediatric intensive care units use the COMFORT-Behavior scale (COMFORT-B) to assess pain in 0- to 3-year-old children. The objective of this study was to determine whether this scale is also valid for the assessment of pain in 0- to 3-year-old children with Down syndrome. These children often undergo cardiac or intestinal surgery early in life and therefore admission to a pediatric intensive care unit. ⋯ Cutoff values for the COMFORT-B set at 17 or higher discriminated between pain (NRS pain of 4 or higher) and no pain (NRS pain below 4) in both groups. We concluded that the COMFORT-B scale is also valid for 0- to 3-year-old children with Down syndrome. This makes it even more useful in the pediatric intensive care unit setting, doing away with the need to apply another instrument for those children younger than 3.

Comparative Study
Eugenol reverses mechanical allodynia after peripheral nerve injury by inhibiting hyperpolarization-activated cyclic nucleotide-gated (HCN) channels.
Mechanical allodynia is a common symptom found in neuropathic patients. Hyperpolarization-activated cyclic nucleotide-gated channels and their current, I(h), have been suggested to play an important role in neuropathic pain, especially in mechanical allodynia and spontaneous pain, by involvement in spontaneous ectopic discharges after peripheral nerve injury. Thus, I(h) blockers may hold therapeutic potential for the intervention of mechanical allodynia under diverse neuropathic conditions. ⋯ Eugenol-induced I(h) inhibition was not mediated by G(i/o)-protein activation, but was gradually diminished by an increase in intracellular cAMP concentration. Eugenol also inhibited I(h) from injured TG neurons which were identified by retrograde labeling with DiI and reversed mechanical allodynia in the orofacial area after chronic constriction injury of infraorbital nerve. We propose that eugenol could be potentially useful for reversing mechanical allodynia in neuropathic pain patients.

Randomized Controlled Trial Multicenter Study Comparative Study
Links between nurses' organisational work environment and upper limb musculoskeletal symptoms: independently of effort-reward imbalance! The ORSOSA study.
The role of psychosocial factors in the development of upper limb musculoskeletal disorders has now been clearly demonstrated. However, only a few studies have analysed the association between the organisational work environment and musculoskeletal disorders in health care workers. The main goal of this study was to test the hypothesis that some specific organisational constraints may be related to upper limb musculoskeletal symptoms experienced by registered nurses, independently of the effort/reward imbalance model and major confounding factors. ⋯ This study identified and quantified specific health care organisational factors that have an impact on nurses' upper limb symptoms, sometimes independently of ERI perception. A prospective study is needed to clarify the causal role of psychosocial and organisational work factors in upper limb injury in nurses. Organisational approaches may be more effective in improving health at work and may also have a longer-lasting impact than individual approaches.
