Dorsal root ganglion stimulation for treatment of central poststroke pain in the lower extremity after medullary infarction

We report a case of relief in central poststroke pain of the lower extremity by stimulation of the dorsal root ganglion (DRG). Central poststroke pain is a poorly understood and even more poorly managed condition that can greatly impact the quality of life. To the best of our knowledge, this investigation is the first to describe the successful treatment of previously intractable chronic pain caused by stroke using DRG stimulation. Noting the anatomical structures and the physiological function, the efficacy of DRG stimulation in central poststroke pain could be explained in a neurophysiological manner. This clinical observation successfully builds on the existing understanding around the pathophysiology of central pain and offers the possibility of nondrug therapy for the treatment of this often refractory chronic pain syndrome.

HIGH cholesterol occurs when you have too much of a fatty substance called cholesterol in your blood. The build-up of this substance can cause a blockage in your blood vessels, leading to heart problems and stroke. New research shares the "hedonically acceptable snacks" which can lower high levels in just weeks.

We examined 9293 individuals from the Copenhagen General Population Study using nuclear magnetic resonance spectroscopy measurements of total cholesterol, free- and esterified cholesterol, triglycerides, phospholipids, and particle concentration. Fourteen subclasses of decreasing size and their lipid constituents were analysed: six subclasses were very low-density lipoprotein (VLDL), one intermediate-density lipoprotein (IDL), three low-density lipoprotein (LDL), and four subclasses were high-density lipoprotein (HDL). Remnant lipoproteins were VLDL and IDL combined. Mean nonfasting cholesterol concentration was 72...

Abbott Laboratories and the National Institutes of Health have formed an alliance to evaluate applications that could help treat chronic pain and progressive movement disorders, like Parkinson’s disease. The collaboration is a part of NIH’s BRAIN (Brain Research through Advancing Innovative Neurotechnologies) initiative to accelerate advancements in neuroscience research. The agreement specifically calls for NIH to use the Abbott Park, IL-based company’s neuromodulation technologies for research related to these NIH initiatives to explore their application for chronic p...

Conclusion and Future Aspects This review summarizes available NTF expression data, compiles existing evidence on the effects of glial NTF signaling in healthy conditions and in disease models (Figure 1), and highlights the importance of this topic for future studies. The relationship between NTFs and glia is crucial for both the developing and adult brain. While some of these factors, such as NT-3 and CNTF, have highly potent effects on gliogenesis, others like BDNF and GDNF, are important for glia-mediated synapse formation. Neurotrophic factors play significant roles during neurodegenerative disorders. In many cases, ...

Conclusion and Perspectives Since their cloning 20 years ago, the physiological importance of TREK-1 channels has continued to grow (Figure 3). Today, TREK-1 channels have been shown to be important and their presence is essential in a number of physiopathological processes. Their involvement in these different processes demonstrate the necessity to design pharmacological modulators, activators or inhibitors, of these channels to correct any TREK-1-related dysfunctions. Despites a number of studies and many molecule screenings, only few putative new drugs were identified. The activators belonging to the ML and BL series ...
