Cultural differences in pain perception exist. Although chronic whiplash-associated disorder (WAD) is well investigated in western countries, little is known about its presentation in Singapore. We studied the neck motion and pain sensitivity in people with chronic WAD in Singapore. ⋯ These findings of sensory hypersensitivity and decreased neck motion in Singaporeans with chronic WAD are consistent with physical impairments reported in western populations.

Comparative Study
A Comparison of Demographic and Psychosexual Characteristics of Women With Primary Versus Secondary Provoked Vestibulodynia.
Provoked vestibulodynia (PVD) is a distressing genital pain condition affecting approximately 12% of premenopausal women. It has been speculated that primary (ie, lifelong) and secondary (ie, acquired) PVD may represent 2 distinct conditions with different etiologies. There is also evidence that primary and secondary PVD subtypes may respond differently to conventional treatments. The goal of this study was to compare the demographic, clinical, and psychosexual characteristics of a large sample of premenopausal women with primary and secondary PVD. ⋯ Overall the findings suggest some important differences in the characteristics of women with primary versus secondary PVD which may have management-related implications.

Randomized Controlled Trial Multicenter Study
Pregabalin in Patients With Inadequately Treated Painful Diabetic Peripheral Neuropathy: A Randomized Withdrawal Trial.
This study used a randomized withdrawal design to evaluate the efficacy of pregabalin versus placebo for pain relief in patients with painful diabetic peripheral neuropathy inadequately treated by other therapies. ⋯ This is the first reported placebo-controlled trial of pregabalin in patients with inadequately treated painful diabetic peripheral neuropathy. Although the primary endpoint was not met, pregabalin was associated with clinically relevant improvements versus placebo in this difficult-to-treat population.

Multicenter Study
The Canadian STOP-PAIN Project: The Burden of Chronic Pain-Does Sex Really Matter?
The Canadian STOP-PAIN Project assessed the human and economic burden of chronic pain (CP) in individuals on waitlists of Canadian multidisciplinary pain treatment facilities. This article focuses on sex differences. Objectives were to (1) determine the pain characteristics and related biopsychosocial factors that best differentiated women and men with CP; and (2) examine whether public and private costs associated with CP differed according to sex. ⋯ This study suggests that women and men who are referred to multidisciplinary pain treatment facilities do not differ significantly in terms of their pain-related experience. However, the aspects that differ may warrant further clinical attention when assessing and managing pain.
