Common symptoms of SFN include: Burning pain, typically beginning in the feet and sometimes spreading to the hands Sharp, shooting, or electric-like pain Numbness and tingling Allodynia (pain from normally non-painful stimuli, like light touch) Hyperalgesia (increased sensitivity to pain) Autonomic symptoms such as abnormal sweating, blood pressure fluctuations, digestive issues, and bladder dysfunction Skin changes in affected areas SFN can be particularly challenging to diagnose because standard nerve conduction studies, which are commonly used to evaluate peripheral neuropathies, primarily assess large fiber function and often miss small fiber damage
Ultrasound offers real-time and penetration advantages, while photoacoustic imaging enhances contrast through molecular-specific absorption
The job of SOD is evidently to catalyse the dissociation of the superoxide radical (O2.-) and, as a result, to eliminate this species from the system [reaction (I)] ( This species apparent cytotoxicity may be due to interactions with redox-active metal ions such as iron and copper, which promote the formation of a more reactive hydroxyl radical
Allergic reactions or injection-site irritation are rare but possible with any formulation
A penetration enhancer which could be solid, semisolid or liquid
