How Sharp is a "Sharp Scratch"? A Mixed Methods Study of Verbal Warnings Issued Before Venipuncture.
Health care providers frequently issue a verbal warning before venipuncture. Communications that induce negative expectations in patients can lead to the "nocebo" response, defined as experiencing greater pain. But is this also true for "sharp scratch"? ⋯ Most health care providers use the verbal warning "sharp scratch" before venipuncture. Most patients find this acceptable and prefer it to no warning. An exception may be elderly patients, who may prefer to be distracted by conversation. "Sharp scratch" makes no difference to the pain experienced compared with a verbal cue.

Chronic pain, sleep disturbances, and depression, which are relevant symptoms of fibromyalgia syndrome, have been demonstrated to be associated with an increased likelihood of suicidal behaviors. Mortality from suicide has been shown to be greater among patients with fibromyalgia. This study aimed to assess the prevalence of suicidal ideation among a sample of patients with fibromyalgia and to evaluate its relationship with the clinical symptomatology of fibromyalgia. ⋯ The results were adjusted by age, sex, total comorbidity, and time since diagnosis with multiple linear regression. The sample comprised 373 patients of whom one hundred and seventy-nine (48%) reported suicidal ideation: 148 (39.7%) reported passive suicidal ideation and 31 (8.3%) active suicidal ideation. Suicidal ideation was markedly associated with depression, anxiety, sleep quality, and global mental health, whereas only weak relationships were observed between suicidal ideation and both pain and general physical health.

Randomized Controlled Trial
Subcutaneous Injection of Diclofenac for the Treatment of Pain Following Minor Orthopedic Surgery (DIRECT study): A Randomized Trial.
Parenteral diclofenac is frequently used for analgesia following minor orthopedic interventions. Currently available diclofenac formulations are for intramuscular (IM) or intravenous injection. A new 1 mL volume formulation of diclofenac containing hydroxypropyl-β-cyclodextrin (HPβCD) allows both SC and IM administration. The objective of this open-label, randomized, parallel group, active-controlled study was to assess the safety and efficacy of 75 mg diclofenac HPβCD, administered SC or IM, compared with IM Voltaren® 75 mg in inpatients undergoing minor orthopedic surgeries with moderate-to-severe postoperative pain. ⋯ Overall, the study results indicate that safety and efficacy were similar irrespective of the diclofenac formulation used; thus, the new SC diclofenac HPβCD has an acceptable tolerability profile and may be considered a valid alternative to IM-delivered diclofenac formulations.

Effects of Topical Diclofenac Plus Heparin (Dhep+H Plaster) on Somatic Pain Sensitivity in Healthy Subjects With a Latent Algogenic Condition of the Lower Limb.
To evaluate whether a diclofenac epolamine + heparin topical (plaster) is more effective than diclofenac plaster alone in reducing deep somatic hyperalgesia in subjects without spontaneous pain and whether the effect is linked to or independent of the anti-edematous action of heparin. ⋯ Topical diclofenac+heparin is significantly more effective than diclofenac alone in reducing muscle hyperalgesia in subjects without spontaneous pain, independently of the anti-edematous action of heparin. The results provide a rationale for the use of diclofenac+heparin also in algogenic conditions without evident signs of injury/edema/hematoma.
