Multicenter Study Comparative Study
Psychiatric comorbidities in a community sample of women with fibromyalgia.
Prior studies of careseeking fibromyalgia (FM) patients often report that they have an elevated risk of psychiatric disorders, but biased sampling may distort true risk. The current investigation utilizes state-of-the-art diagnostic procedures for both FM and psychiatric disorders to estimate prevalence rates of FM and the comorbidity of FM and specific psychiatric disorders in a diverse community sample of women. Participants were screened by telephone for FM and MDD, by randomly selecting telephone numbers from a list of households with women in the NY/NJ metropolitan area. ⋯ Risk of lifetime anxiety disorders, particularly obsessive compulsive disorder and post-traumatic stress disorder, was approximately 5-fold higher among women with FM. Overall, this study found a community prevalence for FM among women that replicates prior North American studies, and revealed that FM may be even more prevalent among racial minority women. These community-based data also indicate that the relationship between MDD and FM may be more complicated than previously thought, and call for an increased focus on anxiety disorders in FM.

Comparative Study
Evidence-based practice for acute low back pain in primary care: patient outcomes and cost of care.
Provider adherence with clinical practice guidelines (CPGs) for acute low back pain (LBP) and its impact on clinical outcomes and cost are controversial. A panel and cross-sectional design was used to determine the rate of provider adherence to the Department of Defense/Veteran's Administration CPG for Acute LBP which included ergonomic and psychosocial intervention. The relationship among adherent care, patient satisfaction, general health, functional outcome, and cost was examined. ⋯ Multivariable regression analyses controlling for demographic variables and perceived health indicated that CPG adherence was related to better functional outcomes, Odds ratio (OR)=1.45 [95% CI=1.31-1.60] and lower healthcare costs (beta=-230.15, p<0.001). Cases receiving more adherent care also reported higher levels of patient satisfaction (beta=0.09, p<0.05) and general health, OR=1.44 [95% CI=1.29-1.60]. Higher levels of adherent care which included efforts to address both ergonomic and psychosocial factors in the course of acute back pain were related to better clinical outcomes and lower costs.

Comparative Study
Sensory neuropathy and signs of central sensitization in patients with peripheral arterial disease.
Patients with peripheral arterial disease (PAD) may develop a broad range of peripheral nerve dysfunctions including pain and sensory deficiencies due to chronic ischemia mostly involving the lower limbs. To investigate the degree of sensory abnormalities in such patients quantitative sensory testing (QST) might be a useful tool. Forty-five patients and 20 controls were enrolled in the present study and underwent QST according to the protocol of the German Research Network on Neuropathic Pain. ⋯ These data indicate that QST can detect sensory abnormalities in PAD patients. While the pattern of decreased perception suggests deafferentation for Abeta-, Adelta-, and C-fiber inputs, the presence of allodynia suggests that central sensitization also plays a role in the pain state of PAD patients. Subgroup analysis points towards a PAD-associated peripheral neuropathy independent of diabetes.

Randomized Controlled Trial Comparative Study Clinical Trial
Physical therapy and active exercises--an adequate treatment for prevention of late whiplash syndrome? Randomized controlled trial in 200 patients.
The aim of this study was to compare the effect of a physical therapy regimen including active exercises with the current standard treatment on reduction of pain 6 weeks and 6 months after whiplash injury caused by motor vehicle collision. Two hundred patients were enrolled in a prospective randomized controlled trial. In the standard group, treatment consisted of immobilization with a soft collar over 7 days. ⋯ However, after 6 weeks, mean pain intensity was significantly (p=0.002) lower in the physical therapy group (1.49+/-2.26 versus 2.7+/-2.78). Similarly, after 6 months, significantly (p<0.001) less pain was reported in the physical therapy group (1.17+/-2.13) than the standard treatment group (2.33+/-2.56). We conclude that a physical therapy regimen which includes active exercises is superior in reducing pain 6 weeks and 6 months after whiplash injury compared to the current standard treatment with a soft collar.

Randomized Controlled Trial Comparative Study
Assessment of persistent pain or distress and adequacy of analgesia in preterm ventilated infants.
Indicators of persistent pain in preterm neonates are poorly defined. In the setting of a double blind, placebo-controlled trial investigating morphine use in ventilated preterm infants (NEOPAIN Trial) we aimed to identify factors that may be useful in assessing persistent pain. Twenty-two babies (morphine 12; placebo 10) were assessed for comfort, pain or distress and clinical staff described the factors they had considered. ⋯ Observation of a good response to handling, good synchrony with ventilation, a "settled" baby, normal blood pressure and heart rate were poor discriminators. Hypotension and poor respiratory drive were noted exclusively in babies receiving morphine infusions. Facial expressions of pain, high activity levels, poor response to routine care, and poor ventilator synchrony were associated with placebo versus morphine therapy, and may be considered useful markers for persistent pain in preterm infants.
