ReviewPredictors of clinical pain intensity in patients with fibromyalgia syndrome.
Central changes in pain processing have been previously reported in patients with fibromyalgia syndrome. These changes include decreased thresholds to mechanical and thermal stimuli (allodynia) and central sensitization, both of which are fundamental to the generation of clinical pain. Therefore, psychophysical measures of central pain processing may be useful predictors of clinical pain intensity of fibromyalgia syndrome patients. ⋯ Particularly, the magnitude of wind-up after-sensations appeared to be one of the best predictors for clinical pain intensity of fibromyalgia syndrome patients (27%). Furthermore, the combination of tender point count, negative affect, and wind-up after-sensations accounted for approximately 50% of the variance in clinical pain intensity of fibromyalgia syndrome patients. Therefore, wind-up after-sensations, tender point count, and negative affect not only seem to represent relevant pain mechanisms but also strongly emphasize their importance for fibromyalgia syndrome pain.

ReviewHow do we diagnose migraine and childhood periodic syndromes?
Migraine remains substantially underdiagnosed and undertreated in the pediatric population. The incidence and prevalence of migraine in the pediatric population is not fully appreciated. ⋯ These criteria are the basis for scientific studies and serve as the foundation for future research and clinical care. In this article, the diagnostic issues related to migraine and childhood periodic syndromes in the IHS 2004 revisions are reviewed.

ReviewWhat is the impact, prevalence, disability, and quality of life of pediatric headache?
Pediatric headache is a common health problem in children, with a significant headache reported in more than 75% by the age of 15 years. Pediatric migraine occurs in up to 10.6% of children between the ages of 5 and 15 years and in up to 28% of adolescents between the ages of 15 and 19 years. ⋯ This impact can be assessed with disease-specific disability and impairment as well as disease non-specific effects on quality of life. The goal of evaluation should be recognition of this impact, whereas the goal of management should be effective treatment that minimizes the impact of this disorder in the short term and for the life of the patient.

Whiplash injuries are very common and usually are associated with rear-end collisions. However, a whiplash injury can be caused by any event that results in hyperextension and flexion of the cervical spine. These injuries are of serious concern to all consumers due to escalating cost of diagnosis, treatment, insurance, and litigation. ⋯ Various researchers have proven that these joints are injured during whiplash injuries and that diagnosis and temporary pain relief can be obtained with facet joint injections. The initial evaluation of any patient should follow an organized and stepwise approach, and more serious causes of neck pain must first be ruled out through the history, physical examination, and diagnostic testing. Treatment regimens should be evidence-based, focusing on treatments that have proven to be effective in treating acute and chronic whiplash injuries.

The American Academy of Neurology recently has published two practice parameters pertaining to children and adolescents with headache. The first focuses attention on the appropriate evaluation of the child with recurrent headache and reviews the data regarding laboratory investigation, electroencephalography (EEG), and neuroimaging. ⋯ If there are abnormalities on the neurologic examination (eg, focal findings, signs of increased intracranial pressure, significant alteration of consciousness) or the coexistence of seizures, then neuroimaging is recommended. The second parameter evaluates relevant data regarding the acute and preventive therapies for pediatric migraine.
