The present study evaluated the relationship between the 2011 American College of Rheumatology fibromyalgia (FM) survey criteria and quantitative sensory testing (QST). ⋯ We demonstrated an association between diffuse hyperalgesia as measured by QST and FM severity in females with knee osteoarthritis. These results suggest that the FM survey criteria may represent a marker of pain centralization in females with potential utility in clinical decision making.

The Effects of Agrin Isoforms on Diabetic Neuropathic Pain in a Rat Streptozotocin Model.
Diabetes mellitus affects 9.3% of the US population and increases risks of surgery and complications. Diabetic neuropathic pain (DNP), one of the main consequences of diabetes mellitus, is extremely difficult to treat. Current medications yield limited benefits and/or have severe adverse effects. Therefore, new, effective treatment is needed. ⋯ Agr50 had a potent suppressive effect on DNP and increased spontaneous inhibitory postsynaptic currents and action potential firing rate from GABA neurons. Therefore, Agr50 may provide a potential therapy for DNP.

Second-degree burn injury is the most common type of burn injury, which usually takes 2-3 weeks for complete healing. However, such patients suffer with intense pain associated with development of hyperalgesia and allodynia. Here, we prepare a silver clay patch using montmorillonite clay, betaine, and silver nitrate. ⋯ Our results show that application of fentanyl-loaded dermal clay (FLDC) dressings for 3 h showed significant increase of paw withdrawal latency (p <0.001) against hyperalgesia starting from 30 min after removal of patch to up to 6 h. Similarly, the FLDC dressings also potentiated the paw withdrawal threshold for up to 4 h after application (p <0.001). From these studies, we can conclude that FLDC dressings are ideal topical formulations for better management of pain in second-degree burns.

Complex regional pain syndrome (CRPS) is not a very common yet typical complication of extremity trauma in the daily practice of a trauma surgeon. The pathophysiology of this puzzling disease is still not completely understood and its impact on the patient cannot be overestimated. ⋯ While a multitude of different diagnostic systems has led to confusion in the past, we now have an internationally accepted, validated and easy to reproduce diagnostic algorithm in the form of the Budapest criteria. The adequate therapy is still a field for debate, but there is now a broad choice of conservative and interventional treatments for the out- and inpatient setting.

Over 25% of Persian Gulf War (PGW) veterans with Gulf War Illness (GWI) (chronic health symptoms of undetermined etiology) developed gastrointestinal (GI) (diarrhea and abdominal pain) and other somatic symptoms. ⋯ Our findings show that there is widespread somatic hypersensitivity in veterans with GWI/GI symptoms that is positively correlated with abdominal pain ratings. In addition, veterans with somatic hypersensitivity that overlap have the greatest number of extraintestinal symptoms. These findings may have a translational benefit: strategies for developing more effective therapeutic agents that can reduce and/or prevent somatic and GI symptoms in veterans deployed to future military conflicts.
