Observational Study
The Relevance of Proprioception to Chronic Neck Pain: A Correlational Analysis of Flexor Muscle Size and Endurance, Clinical Neck Pain Characteristics, and Proprioception.
Impairment in the cervical proprioception and deep flexor muscle function and morphology have been regarded to be associated with chronic neck pain (CNP). ⋯ The results indicated that cervical proprioception was associated neither with deep flexor muscle structure/function nor with clinical CNP characteristics. Left rotation error and local flexor endurance were found relevant to neck pain development.

In a moderated mediation model, this study examined the interaction effect of pain severity and medical evidence on physician judgments of chronic pain. The effects of higher pain severity on physician judgments were expected to be mediated through anticipated clinical burden, but only when medical evidence was low. ⋯ Results did not support the proposed moderated mediation model as all patients were expected to be burdensome across clinical presentations, reflecting negative expectations of patients with chronic pain. Such expectations can have adverse implications for patient-provider communication, shared decision-making, and the delivery of personalized care.

Findings regarding small nerve fiber damage in complex regional pain syndrome type I (CRPS-I) are not uniform, and studies have not included a matched healthy control group. The aim was to assess intraepidermal nerve fiber density (IENFD) in relation to thermal sensitivity of the same skin areas in CRPS-I patients and a gender- and age-matched healthy control group. ⋯ CRPS-I may be associated with bilateral small fiber damage, and perhaps small fiber neuropathy and bilateral disturbances in thermo-sensory perception. These disturbances could stem from a systemic response to injury or might increase the risk of developing CRPS-I after physical trauma.

Multicenter Study Clinical Trial
An Open-Label Study of Sufentanil Sublingual Tablet 30 Mcg in Patients with Postoperative Pain.
To evaluate sufentanil sublingual tablet 30 mcg (SST 30 mcg) for postoperative pain in an older patient population with comorbidities. ⋯ SST 30 mcg was effective and well tolerated for the management of moderate-to-severe acute postoperative pain.

Pain diary assessment in sickle cell disease (SCD) may be expensive and impose a high respondent burden. ⋯ It is possible to simulate five- to six-month daily assessment of pain in SCD. Either one-day-per-week or one-week-per-month assessment yields an equivalent mean and fair regression equivalence.
