Autonomic pain: features and methods of assessment

Postgraduate Medicine
B GandhavadiR G Addison


The distribution of pain originating in the sympathetic nervous system does not match the somatic segmental sensory distribution at the postganglionic level. The two types of distribution are separate and different. At the preganglionic level, fibers show typical segmental sensory distribution, which resembles but is not identical to somatic segmental sensory distribution. Instead, sympathetic pain has its own distribution along the vascular supply and some peripheral nerves. It cannot be called atypical in terms of somatic segmental sensory distribution. Several techniques are available to assess autonomic function in cases of chronic pain. Infrared thermography is superior to any other physiologic or pharmacologic method to assess sympathetic function. Overactivity of sympathetic function in the area of pain is the probable cause of temperature reduction in that area. Accordingly it would appear that in cases in which thermography demonstrates decreased temperature, sympathetic block or sympathectomy would provide relief from the pain.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
