Role of Microglia in Neuropathic Pain.

Microglial cells are specialized macrophage cells of the central nervous system responsible for the innate immunity of the spinal cord and the brain. They protect the brain and spinal cord from invaders, microbes, demyelination, trauma and remove defective cells and neurons. For immune protection, microglial cells possess a significant number of receptors and chemical mediators that allow them to communicate rapidly and specifically with all cells of the nervous tissue.

Acupuncture-induced haemothorax: a rare iatrogenic complication of acupuncture.

This paper reports a rare iatrogenic complication of acupuncture-induced haemothorax and comments on the importance and need for special education of physicians and physiotherapists in order to apply safe and effective acupuncture treatment. A 37-year-old healthy woman had a session of acupuncture treatments for neck and right upper thoracic non-specific musculoskeletal pain, after which she gradually developed dyspnoea and chest discomfort. After some delay while trying other treatment, she was eventually transferred to the emergency department where a chest X-ray revealed a right pneumothorax and fluid collection.
