To evaluate the safety of low-dose tanezumab in the treatment of knee or hip osteoarthritis (OA). ⋯ These results demonstrate that RPOA and APS should be the most concerning AEs when using tanezumab in OA patients. Additional data are needed to define the optimal dose to minimize risk and to determine the optimal subjects to receive this treatment.

Persistent posttraumatic headache (PPTH), one of the most common symptoms following mild traumatic brain injury, is often associated with substantial functional disability. The objective of this study was to assess the contribution of demographics, headache characteristics, and psychological symptoms to disability associated with PPTH. ⋯ Individuals with PPTH had substantial psychological symptoms and headache-related disability. Disability was partially explained by age, headache frequency and intensity, and trait anxiety. Holistic management of patients with PPTH to address headaches and psychological symptoms might reduce headache-associated disability.

Radiation therapy is used as a form of treatment for various neoplastic diseases. There are many potential adverse effects of this therapy, including radiation-induced neurotoxicity. Radiation-induced brachial plexopathy (RIBP) may occur due to the fibrosis of neural and perineural soft tissues, leading to ischemic damage of the axons and Schwann cells. ⋯ Pain is present in the shoulder and proximal arm and is typically mild to moderate in severity. Diagnosis is often made based on clinical presentation and evaluation of imaging to rule out concurrent malignant etiologies of the brachial plexus. Current recommended treatment includes physical therapy and medical management with anticonvulsants, tricyclic antidepressants, and selective serotonin-norepinephrine reuptake inhibitors.

To investigate the pain referral area (number of pixels) and extent (vector length) as elicited from increasing intensities of pressure-induced pain at the shoulder. ⋯ Pressure intensity at PPT+30%, but no more, produces the greatest referred pain area as compared with the traditional pressure intensity of PPT+20%. Thus, the intensity of PPT+30% may be ideal for exploring the mechanisms of referred pain. The extent of the pain represents an independent expression of the intensity of the provoking stimulus and may be more closely related to the location of the stimulus.
