Multicenter Study Clinical Trial
Parents' views about infant pain in neonatal intensive care.
The purpose of this study was to describe parents' perceptions and feelings about their infant's pain experience and pain care in the neonatal intensive care unit. ⋯ The findings from this study expand knowledge about how parents understand and respond to the difficult situation in which their newborn infant is subjected to essential but painful procedures. The findings provide direction for research and clinical practice interventions aimed at: 1) helping parents to gain knowledge and correct their misperceptions; 2) engaging parents in meaningful dialog about their concerns and preferences for involvement; and 3) helping parents to develop effective coping strategies to reduce psychologic distress related to their infant's pain.

Randomized Controlled Trial Clinical Trial
Patterns of pain variation related to myogenous temporomandibular disorders.
Myogenous temporomandibular disorders are characterized by jaw muscle pain. The aims were: 1) to characterize this pain generally in terms of intensity, frequency, duration, and behavior across a period of 2 weeks; 2) to identify main intraday pain patterns and to examine whether subgroups of patients in this respect differed in clinical, demographic, pain and sleep variables, psychosocial factors, and use of medication; and 3) to investigate some possible interday trends of pain intensity at a group level. ⋯ Two main daily pain patterns occur in patients with myogenous temporomandibular disorders (79%: maximal pain late in the day; 21%: early in the day), which might be related to differences in processes that influence pain sensitivity and patterns of jaw muscle activation. The interday similarities in pain level suggest that a sustained influence of counseling after the intake or an influence of a common behavioral pattern with a cycle duration of a week are not involved.

Randomized Controlled Trial Clinical Trial
The effectiveness of multidisciplinary rehabilitation in the treatment of fibromyalgia: a randomized controlled trial.
To assess the effectiveness of multidisciplinary rehabilitation in the treatment of fibromyalgia in comparison to standard medical care. ⋯ Positive health-related outcomes in this mostly unresponsive condition can be obtained with a low-cost, group multidisciplinary intervention in a community-based, nonclinical setting.

Comparative Study
Prevalence of clinical hypertension in patients with chronic pain compared to nonpain general medical patients.
In healthy individuals, elevated blood pressure is associated with diminished acute pain sensitivity. These cardiovascular/pain regulatory system interactions appear altered in patients with chronic pain; elevated blood pressure is associated with increased acute and chronic pain responsiveness. If these alterations reflect failure of overlapping systems modulating pain and blood pressure, it was expected that prevalence of clinical hypertension would be increased in the chronic pain population. ⋯ These results suggest that chronic pain may be associated with increased risk of hypertension. Factors that may underlie this association are discussed.

Case Reports
Injections of botulinum toxin type a produce pain alleviation in intractable trigeminal neuralgia.
To report the effects of local injections of botulinum toxin type A regarding pain relief and long-term control in a patient with intractable trigeminal neuralgia. The patient was a 75-year-old man with trigeminal neuralgia in the left hemifacial region. His pain was unbearable and could not be controlled by carbamazepine, amitriptyline, or blocked by infiltration of a glycerol solution or phenol. ⋯ No side effects were observed on the site of injection and on the patient's clinical state. The authors have been able to reduce trigeminal neuralgia pain with botulinum toxin type A injections in the V1, V2 territory during all the period of study, as well as to withdraw all medication. Interestingly, there was concomitant reduction of pain also in V3, which was not injected.
