ABSTRACT
Notalgia paresthetica (NP) is a chronic localized itch, affecting mainly the inter-scapular area particularly between the T2-T6 dermatomes. Occasionally it has a more widespread distribution and involves the shoulders, back, and upper chest. There are no specific cutaneous signs, apart from those attributed to scratching and rubbing. Various etiologies have been reported, but the cause of NP is not established. The current hypothesis regarding its etiology postulates that a neuropathic itch develops due to nerve entrapment of the posterior rami of spinal nerve arising at T2-T6. Another recent documented case showed an increase in the number of intradermal nerves by neural immunochistochemistry staining of S-100 protein, protein gene product 9.5 (PGP 9.5). Herein, we experienced an uncommon case of NP of the back and tried to clarify pathogenesis by using quantitative sensory testing, such as neurometer and Von-Frey filaments. Also, we performed neural immunochemistry to confirm an increase in nerve fibers at the site of the lesion.

It has been told that acupuncture to the stellate ganglion suppresses the sympathetic activity. By using 15 patients, we made measurements of electrical current of the skin at the 24 typical determinate points of Ryodoraku with a Neurometer before and after electrical acupuncture to the right stellate ganglion.<br>After 20min rest in the supine position, average values of 6 points of the right and left upper extremities decreased with 30% and 27%, and those of the right and the left lower extremities decreased with 34% and 31%, respectively.<br>Immediately after 30min of electrical acupuncture, average values of 6 points of the right and left upper and the right and left lower extremities increased with 9%, 12%, 17% and 9%, respectively.<br>Twenty minutes after the right stellate ganglion block, average values of 6 points of the right upper extremity decreased with 16%, and those of the left one, the right and left lower extremities decreased with 9%, 18% and 14%, respectively.<br>These data suggest that acupuncture to the stellate ganglion stimulates the sympathetic tone by showing increase of electrical conductivity of the skin, while the stellate ganglion block shows the decrease.
ABSTRACT
It is said that Ryodoraku reflects the dysfunction of the autonomic nerve in spite of no objective evidence for the theory.<br>Using 60 patients received right stellate ganglion block, we measured 24 typical determinate points of ryodoraku with a neurometer and an electrodermometer.<br>With a neurometer, an average current value of 6 points of the right upper extremity decreased in 52% as well as that of 6 points of the left decreased in 62%. Both the right and the left lower extremities decreased in 91% and 85%.<br>With an electrodermometer, the average impedance of the right upper extremity increased in 108%.<br>Finally, the sympathetic blockade showed decrease in a current value with a neurometer and increase in impedance with an electrodermometer.
ABSTRACT
We made the electrophotography which is able to visualize the distribution of electroconductivity to the skin.<br>According to an electric quantity, reducing KI into iodine, we got a compound of AgI with galvanochemical response and took a picture of a galvanic skindistribution on it. We may be able to apply both the A. C. and the D. C. in power supply. In order to take a good picture of electroconductive points, we used 12V of the D. C.. In this case, an electric quantity was<br>3.6×10<sup>-4</sup>-4.8×10<sup>-3</sup>W.Min./cm<sup>2</sup>
