Binucleated and multinucleated forms of plasma cells in synovia from patients with rheumatoid arthritis

A morphological examination of synovial tissue from 25 patients with rheumatoid arthritis revealed that binucleated or multinucleated plasma cells were present in all samples and absent in synovia obtained from 16 control patients. Plasma cells containing two, three of four nuclei constitutet a mean 3% of the total plasma cell population. They were aways found amongst plasma cell infiltrates and in close association with small blood vessels. Ultrastructural analysis found no evidence of cellular membranes separating the individual nuclei in binucleated or multinucleated plasma cells, suggesting that the cells did not arise from fusion. Some of these plasma cells had a diameter approaching 100 μm, and many were in intimate contact with macrophages. The demonstration of a few cells with mitotic figures within the infiltrates suggests that the maintenance of plasma cell numbers in rheumatoid synovium may depend, in part, upon their local proliferation.

Creating empowering meaning: an interactive process of promoting health with chronically ill older Canadians

Many health promotion approaches afford education about disease prevention and enhancement of one's health status. But strategies for enabling older people with chronic illness to better mobilize their resources for everyday living still require development. This practical action research study explored the experiences of 13 purposefully selected older persons who participated in a health promotion intervention premised on the adult education theory of perspective transformation. Findings illuminate health promotion through a holistic interactive process in which professional and chronically ill older person together evolved a caring relationship and enhanced conscious awareness of life and health experiences. Five health-promoting strategies were identified: building trust and meaning; connecting; caring; mutual knowing; and mutual creating. Researchers suggest several important directions to refine professional practice approaches and health care delivery systems in order to promote the health of older persons with chronic conditions.     

Spinal cord stimulation in the treatment of failed back surgery syndrome

A significant number of patients undergoing lumbar spine surgery do not obtain pain relief. Such patients with chronic low back or lower extremity pain may be difficult to treat. A frequent component of therapy is the use of spinal cord stimulation to help control pain. With careful patient selection, many patients can achieve reasonable levels of pain relief. We review recent clinical reports, including prospective and randomized studies, that demonstrate up to three quarters of patients implanted with a spinal cord stimulator for the treatment of failed back surgery syndrome may benefit from its use. This technology must not be indiscriminately applied. Careful patient selection and a period of trial stimulation are vital to the successful use of spinal cord stimulation as treatment for chronic pain.
