Malignant peripheral nerve sheath tumors are extremely rare soft tissue sarcomas. Among various locations, the trunk and extremities are the most commonly involved sites, with only 15% of such lesions occuring in head and neck region. Here, we report a case of a 74-year-old male who presented with forehead swelling and right eye deviation. Computed tomography images revealed a tumor involving the frontal sinus, ethmoid sinus, and the orbital cavity. The patient underwent a surgical excision of the lesion, which histopathological examination revealed to be a malignant peripheral nerve sheath tumor.

This paper proposes enhanced features for the Universal Telecommunications (UPT), voice authentication and voice synthesis, using the specialized resources functions in the Intelligent peripheral(IP). The proposed voice authentication is able ti provide simple and user-friendly security mechanism and to prevent unauthorized users from fraudulently using the UPT number. Also, traditional UPT service deliveries only fixed message to the UPT user, but the proposed UPT service can support flexible message transfer by use of the voice synthesis.

Objectives : This study was designed to evaluate clinical evidence of acupuncture treatment for peripheral facial palsy in South Korea. Methods : All process was independently proceeded by two investigators. Literature search was performed in 9 databases from their inception to February 2013. Searched reports was twice excluded for title, abstract and body. And then, data extract and analysis was done before assessing risk of bias by Cochrane Handbook. Results : 10 randomized controlled trials(RCT) were finally included. 4 RCT handled postauricular pain with facial palsy. All articles at least used in combination with two treatments. Interventions like pharmacopuncture, electroacupuncture, scalp acupuncture etcetera were conducted as treatment to evaluate efficacy, and some study reported advantageous effects of treatment group compared to baseline or control group. Adverse events didn't referd to in any studies. In assessing risk of bias, indefinite and uncertain information made all included trials to have a high risk of bias. Conclusions : Because of methodological deficit, there is no sufficient evidence to allow any conclusion about the efficacy of acupuncture for peripheral facial palsy. Therefore, well designed trials with high quality is needed from now on.

Purpose: The purpose of this study was to examine the effect of patient surveillance on nurses' adherence to the guidelines on peripheral vascular catheter management. Method: A one group time series design was used. Seventy six nurses participated in the study. The data were collected from October 1 to November 4, 2008. Result: The effects of patient surveillance were significant on nurses' average adherence rates to the guidelines estimated by observers and by themselves, and the levels of nurses self recognition on the importance of the guidelines. In addition, overall occurrence rates of phlebitis tend to decrease after patients surveillance. Even though 33 nurses didn't follow the guidelines perfectly, most patients did not provide feedbacks to the nurses' non-adherence. Among the nurse participants, 36.8% answered that patient surveillance was acceptable. Conclusion: This study found that patients with peripheral catheters could positively influence nurses' adherence to the catheter management guidelines. Therefore, inviting patients in nursing activities could benefit to the quality of patients care. However, it seems essential to create an environment fostering nurses' acceptance of the patients' surveillance. Further research warrants the potential benefits of the patient's participations in nursing activities.

The role of cultured bone marrow stromal cells (BMSCs) in peripheral nerve regeneration was examined using an established rabbit peroneal nerve regeneration model. A 15-mm peroneal nerve defect was bridged with a vein filled with BMSCs $(1{\times}10^6)$, which had been embedded in collagen gel. On the contralateral side, the defect was bridged with a vein filled with collagen gel alone. When the regenerated tissue was examined 4, 8 and 12 weeks after grafting, the number and diameter of the myelinated fibers in the side with the BMSCs were significantly higher than in the control side without the BMSCs. This demonstrates the potential of using cultured BMSCs in peripheral nerve regeneration.

Purpose: This study aimed to investigate the effects of foot bath therapy on the symptom intensity, distress, and interference with usual activities due to chemotherapy-induced peripheral neuropathy (CIPN) in patients with metastatic and recurrent cancer. Methods: Foot bath therapy was administered to the experimental group for >8 sessions in 2 weeks, and the chemotherapy-induced peripheral neuropathy assessment tool (CIPNAT) was used to measure its effects on the symptom intensity, distress, and interference with usual activities due to CIPN. SPSS was used to perform data analyses including descriptive statistics, chi-square test, Fisher's exact test, t-test, paired t-test, and repeated measures ANCOVA. Results: A statistically significant difference in the variation of the symptom intensity, distress, and interference with usual activities due to CIPN was observed between the two groups; however, a statistically insignificant difference was observed between the groups and time of interaction. Conclusion: Foot bath therapy can be used as a simple and effective clinical or home care nursing intervention to improve the symptom intensity, distress and interference with usual activities due to CIPN.

In general, the physiological systems have shown nonlinear complex phenomena. This study analyzes nonlinear characteristics of the flow of peripheral blood vessel dynamics in physiological systems using chaos theory. We performed this study by means of several quantity methods and power spectrum. The quantity methods are a phase space reconstruction and a poincare's map. And the power spectrum method is a conventional linear analysis. Experimental data have been acquired from examining 10 diabetic patients, and 10 control subjects in initial stable state. In acquisition experminetal data, we anlysized the differences of nonlinear characteristics between diabetic group and control group. The results of quality analysis methods showed the flow of peripheral blood vessel had the nonlinear and chaotic characteristics, screening a strange attractor on reconstructed phase space. In conclusion, the flow dynamics of peripheral blood vessel had a chaotic behavior of nonlinear dynamic systems, dynamic system, and differences of characteristic of nonlinear dynamic system.

Purpose: Malignant peripheral nerve sheath tumors (MPNSTs) are rare neoplasms, usually arising from somatic soft tissues or peripheral nerves. Primary MPNST of the scalp is extremely rare. The case is being reported for its rarity. Methods: A 53-year-old female was presented with a scalp mass on vertex area. The tumor was localized in scalp skin and did not invade underlying periosteum or skull and treated with complete surgical excision followed by adjuvant chemotherapy and radiotherapy. Results: Histologically, the tumor showed malignant spindle cells with focal S-100 positivity on immunohistochemistry and a diagnosis of MPNST was made. Conclusion: Authors experienced a rare case of primary scalp MPNST and report the case.

The objective of this study was to investigate the dynamic neural mobilization program on the changes in muscle activity and nerve conduction velocity (NVC) in stroke patients. The participants were sampled and randomly divided into experimental group I (n=12) who underwent arm neural mobilization and experimental group II (n=13) who underwent arm dynamic neural mobilization. As the pretest, peripheral NVC of the radial, median, and ulnar nerves were measured using the Viking Quest; the biceps brachii, brachioradialis, flexor carpi radialis, and extensor carpi radialis activities were measured with sEMG. Each intervention program consisted of 10 trials per set and three sets per session. The intervention programs were performed once daily for four weeks (four days/week). Posttest measurements were taken equally as the pretest measurements. Significant differences in peripheral NVC in all sections of the radial and median nerves and wristbelow elbow and below elbow-above elbow areas of the ulnar nerve, as well as in muscle activity of all muscles except the biceps brachii. These findings indicate that dynamic neural mobilization was effective in increasing peripheral NVC and altering the muscle activity.

The purpose of this study was to investigate useful manual therapy techniques for peripheral facial nerve palsy and to propose guidelines to be applied for current manual therapy techniques. Several databases were searched to find manual therapies for facial palsy. These therapies included cervical, and temporomandibular joint chuna manual therapy, proprioceptive neuromuscular facilitation, neuromuscular re-education, facial exercise, and mime therapy. Both cervical, and temporomandibular joint chuna manual therapy release nerve compression, helping blood circulation and nerve conduction. Proprioceptive neuromuscular facilitation uses irradiation, bilateral activation, and eccentric facilitation to improve muscle power and symmetry. Neuromuscular re-education, as a retraining tool for facial movement patterns, enhances neuromuscular feedback. Facial exercise helps the patient continuously move and massage facial muscle themselves. Mime therapy aims to develop a conscious connection between the use of certain muscles and facial expressions. The use of facial chuna manual therapy for peripheral facial nerve palsy can stimulate the proprioceptive neuromuscular receptors in the face. Peripheral facial nerve palsy has 4 phases; progress phase, plateau phase, recovery phase, and sequelae phase. Each phase needs different treatments which include relaxation, assistance, resistance, origin-insertion extension, and nerve pathway expansion.
