Randomized Controlled Trial
Short-term treatment with parecoxib for complex regional pain syndrome: a randomized, placebo-controlled double-blind trial.
Complex regional pain syndrome (CRPS) is characterized by signs and symptoms of peripheral inflammation, which leads to peripheral neural sensitization associated most frequently (in about 70%) with blunt pressure hyperalgesia. Therefore, we hypothesized that treatment of CRPS patients with a selective COX-2-inhibitor would alleviate the abnormally low pressure pain threshold (PPT) and reduce pain intensity and edema. ⋯ In the present proof-of-concept trial, short-term treatment with the selective COX-2-inhibitor parecoxib influenced neither PPT nor edema or pain. COX-2 might be less important than previously assumed. However, the results are limited due to the small number of patients, short-term treatment, and focus on the PPT, which could have led to false negative results of the present study and covered the expected therapeutic effect.

Chronic pelvic pain (CPP), defined as a noncyclical pain lasting for more than 6 months can lead to lower physical performance and quality of life in women. CPP is a worldwide problem affecting women of all ages. However, health care professionals and researchers, due to its complex nature and the lack of knowledge surrounding the condition, frequently neglect CPP. Subsequently, basic data and knowledge regarding CPP remain incomplete. ⋯ Based on these articles, prevalence in general ranged between 5.7% and 26.6%. There were many countries and regions without basic data in the field of CPP. This review shows the paucity of studies, especially multidisciplinary researches with multifactorial views on CPP. Multidisciplinary studies would provide more reliable data for estimating the prevalence of CPP and its psycho-socioeconomic burden, as well as finding its etiologies and characteristics. This would be the first step towards better treatment and care for women with CPP.

Treating pain associated with acute coccyx fractures can be challenging. Intranasal calcitonin has been used to treat acute pain after vertebral fracture, and may even accelerate fracture healing. However, intranasal calcitonin has never previously been published as part of the treatment of acute coccyx fractures. ⋯ We propose that clinicians consider use of intranasal calcitonin for the treatment of pain due to acute coccyx fractures.

The health and efficacy profiles of Gralise® in the treatment of pain from spinal stenosis and radicular symptomatology have not been measured. A review of the current literature indicates that no studies exist that evaluate the safety and efficacy profiles of Gralise® in the treatment of pain from spinal stenosis and radicular symptomatology. ⋯ Gralise demonstrated moderate efficacy with reduced pain intensity and increased sleep and was well tolerated in spinal stenosis patients with radicular symptoms.

Image guided intercostal blocks are commonly performed and considered relatively safe. Chemical denervation is commonly used in clinical practice for treatment of chronic non-cancer associated pain. ⋯ This case offers several lessons for a pain specialist including 1) the potential for a neurologic catastrophe (spinal cord injury) from aqueous neurolytic intercostal blocks despite "safe" contrast spread; 2) potential mechanisms of neurogenic injury with intercostal blocks; 3) review of modifiable factors to decrease the risk of neurogenic injury; and 4) review of potential interventions (steroids, lumbar drain) to improve outcome in the setting of iatrogenic procedural related spinal cord injury.
