Purpose : The purpose of this study was to investigate the effects of music intervention upon lighting on stress. Method : The participants 60 college students, were divided three groups. Two groups were apply each music and bright lighting(bright lighting groups) and music and dark lighting(dark lighting groups) during 13minutes at Snozelen and the other group was control group. Each groups were assessed stress resistance, activity of parasympathetic nerve, activity of sympathetic nerve, balance of ANS, physical arousal by EKG of CANS 3000, at before and after other each intervention. The analyses were performed using version of SPSS 17. Result : The change rate of bright lighting group was showed statistically significant decrease in stress resistance compared to control group. And the change rate of dark lighting group was showed statistically significant decrease in resistance stress, activity of parasympathetic nerve, and balance of ANS compared to control group and statistically significant increase in stress resistance and activity of parasympathetic nerve compared to bright lighting group. Conclusion : The results of this study indicate that music intervention on dark lighting is more effective on decrease of stress than application of bright lighting and general lighting.

Although various criteria on the diagnosis of diabetic neuropathy are applied from trial to trial, being tailored in concert with its purpose, the utmost evidences of the diagnosis are subjective symptoms and objective signs of neurologic deficit. The application and interpretation of auxiliary electrophysiological test including nerve conduction study (NCS) should be made on the context of clinical pictures. The evaluation of the functions of small, thinly myelinated or unmyelinated nerve fibers has been increasingly stressed recently with the advent of newer techniques, e.g., measurement of intraepidermal fiber density, quantitative sensory testing, and autonomic function test. And the studies with those techniques have shed light to the nature of the evolution of diabetic neuropathy. The practical application of these techniques to the diagnosis of diabetic neuropathy in the individual patients, however, should be made cautiously due to several shortcomings: limited accessibility, wide overlapping zone between norm and abnormality with resultant unsatisfactory sensitivity and specificity, difficulty in performing subsequent tests, unproven quantitative correlation with clinical deficit, and invasiveness of some technique. NCS, as an extension of clinical examination, is still the most reliable electrophysiological test in evaluating neuropathy and gives the invaluable information about the nature of neuropathy, whereas the newer techniques need more refinement of the procedure and interpretation, and the accumulation of large scaled data of application to be considered as established diagnostic tools of peripheral neuropathy.

Zoster sine herpete (ZSH) is one of the atypical clinical manifestations of herpes zoster (HZ), which stems from infection and reactivation of the varicella-zoster virus (VZV) in the cranial nerve, spinal nerve, viscera, or autonomic nerve. Patients with ZSH display variable symptoms, such as neuralgia, however, different from HZ, ZSH show no zoster, which makes clinical diagnosis difficult. ZSH not only causes initial symptoms, such as neuropathic pain in the affected nerve, Bell palsy, and Ramsay Hunt syndrome, but also postherpetic neuralgia and fatal complications such as VZV encephalitis and stroke. The misdiagnosis of ZSH and tardy antiviral treatment may lead to severe ZSH sequelae. We review the publications related to ZSH, especially its diagnosis with VZV DNA and/or anti-VZV immunoglobulin (IgG and IgM). More work about ZSH, especially ZSH epidemiological survey and guidelines for its diagnosis and treatment, are needed because most of the present studies are case reports.

Background: Occipital neuralgia is characterized by pain, usually deep and aching, in the distribution the second and/or third cervical dorsal root. Two broad groups of patients include primary occipital neuralgia with no apparent etiology and secondary neuralgia with structural pathology. Patients with occipital neuralgia can develop autonomic changes and hyperesthesia. In patients who have not improved with conservative treatment, we have carried out various nerve blocks and evaluated the effectiveness. Methods: In a series of 20 occipital neuralgia patients with no apparent etiolgy, we have carried out great occipital nerve blocks with needle TEAS. In patients who have not improved more than 75% on VAS with great occipital block, we have carried out C2 ganglion blocks and in patients who have not improved more than 75% with C2 ganglion block, C3 root blocks, C2/C3 facet joint blocks have been carried out in due order. Results: In 3 patients out of 10 patients who have not improved with great occipital nerve block, C2 ganglion block led to pain relief. A good response of C3 root block was achived in 2 of 7 patients without response to C2 ganglion block and C2/C3 facet joint block led to improvement in 1 of 5 patients without response to C3 root block. Conclusions: Nerve blocks like great occipital nerve block, C2 ganglion block, C3 root block, or C2/C3 facet joint block were effective in the patients who have not improved with conservative treatment.

Schwannomas are tumors which originate from the neuroectodermal Schwann cell of cranial, intraspinal, peripheral and autonomic nerve sheaths, and they are solitary, benign, slow growing and well encapsulated neoplasm. Schwannomas are usually asymptomatic. No strong gender or age predominance exists. The incidence of extracranial schwannomas in the head and the neck region varies from 25~45%. In addition, schwannomas are rare in the maxillary sinus or buccal space. In this paper, it diagnosed and treated a 54-years old female patient, who had schwannoma in the maxillary sinus derived from infraorbital nerves, the branch of the left trigeminal nerve, and a 19-years old male patient, who had schwannoma arose in the buccal space derived from the buccal branch of the right facial nerve. There was no particular complication except sensory extinction of the nerve in the female patient and paralysis by the nerve in the male patient. It is determined those two cases of schwannoma in the rare portion is valuable and herein, it reports those with literature discussions.

The nature of the interactions between the vestibular and autonomic systems is complex and has not been fully defined. Vestibuloocular reflex induced by sinusoidal rotation and activity of the autonomic nerves in the heart were measured to investigate the interactions between the vestibular system and the autonomic nervous system in healthy adults. Eye movement induced by sinusoidal rotation of the whole body or optokinetic stimulation at 0.04 Hz was analyzed in gain, phase, and symmetry. EKG was measured during vestibular stimulation and analyzed in heart rate variability including mean R-R interval, standard deviation (SD) and coefficient of variance (CV) of R-R interval, and power spectrum of low frequency region (LF) and high frequency region (HF). Gain of eye movement was 0.65${\pm}$0.03 by ratatory stimulation, 0.70${\pm}$0.02 in optokinetic stimulation, 0.08${\pm}$0.02 in visual suppression, and 0.84${\pm}$0.04 in visual enhancement. In R-R interval, resting condition (control) was 0.82${\pm}$0.03 sec, and visual suppression showed significant increase and visual enhancement did significant decrease compared with control (p<0.01).CV was 0.06${\pm}$0.02 in control and visual enhancement increased significantly (p<0.05). In LF/HF control was 1.40${\pm}$0.23, which was not different from rotatory or optokinetic stimulation. But visual suppression decreased LF/HF significantly and visual enhancement increased significantly compared with control (p<0.01). These results suggest that degree of gain corresponds with LF/HF and increased gain in visual enhancement is deeply related to the activity of sympathetic nerves.

Objectives : This study was designed to investigate the effect of PC6 and SP4 on autonomic nerve system in healthy adults. Methods : 22 healthy adults were recruited and randomized into the study group or control group. The study group (real acupuncture group) was acupuncturcd on PC6 and SP4. The control group (sham acupuncture group) was acupunctured superficially near PC6 and SP4 but not the exact points. The subjects rested for 10 minutes, and were then acupunctured. After 15 minutes, acupuncture needles were removed and the subjects rested for another 15 minutes. Heart rate variability(HRV) was continuously measured during the study period by FM-150 (digital Holter ECG recorder). Results : In the real acupuncture group. LF(low frequency) significantly decreased during the acupuncture period(p<0.05). LF/HF ratio also had a significant decrease during acupuncture period and the decrease was maintained during the post-treatment period as compared with the pre-treatment period. In the sham acupuncture group. LF significantly increased during the acupuncture period but LF/HF ratio had no significant changes. Conclusions : The results suggest that acupuncture on PC6 and SP4 can increase parasympathetic activity and balance autonomic nervous system.

Neurilemmomas are well-encapsulated, benign, slow-growing tumors originating from Schwann cells of the nerve sheath surrounding cranial, peripheral, or autonomic nerves. Intraoral neurilemmomas are relatively rare and have a wide variety of morphologic and radiologic features. This makes differential diagnosis difficult, and only histopathological features can lead to a definitive neurilemmoma diagnosis. In this report, we present the case of a 30-year-old woman whose chief complaint was a solitary, nodular mass on the right floor of the mouth. After computed tomography and magnetic resonance imaging, we performed an incisional biopsy that showed the typical characteristics of a neurilemmoma. The mass was removed completely through an intraoral surgical approach. Despite losing a portion of the lingual nerve, the patient did not complain of any specific discomfort. Wound healing was uneventful and there were no signs or symptoms of recurrence.

Complex regional pain syndrome (CRPS) is a chronic regional pain disorder that most frequently affects the limbs. It is characterized by hyperalgesia, allodynia, edema, motor disturbance, and vasomotor instability, and typically occurs following surgery or trauma. In type-I CRPS there is no confirmed nerve injury, while peripheral nerve injury is present in type-II CRPS. The multifactorial pathophysiological etiology of CRPS includes inflammation, autoimmune responses, abnormal cytokine production, autonomic dysfunction, altered blood flow, psychological factors, and central cortical reorganization. There are no specific laboratory diagnostic tools for CRPS, and so it is diagnosed clinically. The Budapest criteria are currently the most-accepted diagnostic criteria.

We investigated the activities of autonomic nervous system during foot bathing. The effect of foot bathing was evaluated for four subjects by observing the characteristic of heart rate variability and bodily temperatures. The foot bathing was done with a commercial foot spa (Duches Co.) utilizing the four functional modes of the spa for two different temperatures of $35^{\circ}C\;and\;40^{\circ}C$. The four functional modes were clam, vibration, air bubbles, and both vibration and air bubbles. The experimental results showed that the temperature of foot and that of face right after foot bathing were not that different from each other. But, for heart rate variability, the activation of parasympathetic nerve showed distinctive increase at $40^{\circ}C$ of water temperature. In the analysis of heart rate variability for different functional modes, the change was not distinctive for different modes at $35^{\circ}$ of water temperature. However, at $40^{\circ}C$, the activation of sympathetic nerve showed distinctive increases with the increase in the complexity of functional modes.
