Malignant peripheral nerve sheath tumors (MPNSTs) are very rare sarcomas derived from various cells in the peripheral nerve sheath. Malignant peripheral nerve sheath tumors have a known association with neurofibromatosis type 1. Diagnosis of MPNSTs is difficult in patients with chronic pain, when MPNST occurs at an overlapping area of chronic pain. Therefore, the diagnosis can be missed unless clinicians pay attention to the possibility of this disease. Here in, we report a case of concurrent malignant peripheral nerve sheath tumor with complex regional pain syndrome type 1. A 44-year female patient, who was diagnosed with complex regional pain syndrome (CRPS) type 1 in her left ankle, visited our clinic because of aggravated pain. The cause of the aggravated pain was revealed as concurrent MPNST in the left common peroneal nerve territory, which overlapped the site of pain from CRPS.

It is well known that the acupuncture has been used effectively for the relief of certain types of pain. Although the precise mechanism of action of acupuncture analgesia is unknown, it is generally accepted that their analgesic properties are related to the activation of endogenous opiate system in central nervous system. And it is suggested that pain-relieving properties of acupunture may be related to a stimulation of peripheral nerve underlying the acupuncture point on the skin. However, the efficacy of acupuncture has no relationship between the site of pain and the acupuncture point. Consequently, the present study was undertaken to investigate electroacupuncture analgesia in relation to the site of peripheral nerve stimulation. Cats were decerebrated ischemically and the flexion reflex as an index of pain was elicited by stimulating the sural nerve (20V, 0.5 msec duration) and recored as a compound action potential from the nerve innervated to the posterior biceps femoris muscle in the ipsilateral hindlimb. Bilateral common peroneal nerve and contralateral superficial radial nerve were selected as the site of peripheral nerve stimulation. For the stimulation of peripheral nerve, a stimulus of 20 V intensity, 2 msec-duration and 2 Hz-frequency was applied for 60 min respectively. The results obtained are summarized as follows: 1) Both stimulation of contralateral common peronal nerve and contralateral superficial radial nerve did not change the flexion reflex and there were no significant differences between them. 2) Stimulation of ipsilateral common peroneal nerve markedly depress the flexion reflex, the effect being reversed by naloxone application. These results suggest that stimulation of ipsilateral common peroneal nerve has the analgesic effect but both stimulation of contralteral common peroneal nerve and contralateral superficial radial nerve to the pain site where flexion reflex was elicited have no analgesic effect.

To investigate the effects of exercise-training on fat distribution several indicators of body fatness(percent body fat skinfolds thickness body circumference) were assessed in 128 healthy male subjects submitted to an 8-wk high intensive exercise-training. The subjects(average age=20.3$\pm$1.3 yrs) exercised 5 days/week. Daily energy intake and expenditure wee recorded. The results obtained are summarized as follows : 1) Through exercise-training lean body mass increased significantly (changes : 0.5$\pm$1.5kg; p=0.000) decreased significantly. 2) Suprailiac was the most reduced site by exercise-training among eight site skinfolds. Central skinfolds were changed more by exercise-training than peripheral skinfolds with reduction of 1.7$\pm$2.1mm and 0.4$\pm$1.8mm respectively. Central site circumferences were reduced more by exercise-training than peripheral site circumferences. 3) As a result of analyzing 12 of the fattest(top 10% of weight) and 12 of the leanest men(bot-tom 10% of weight) it indicated that there was a significant reduction of fat tissue in body composition and skinfolds thickness for the fat group. However there was no significant change for the lean groups. 4) Correlational analysis showed that predicting changes in body fat by infrared(NIR) measurement seemed to be closely associated with changes in body fat by Kim's equation and Katch's equation in young men.

Thyrotropin binding inhibitory immunoglobulin (TBII) and thyroid stimulating antibody (TSAb) activities were measured in the thyroidal and peripheral venous blood samples at the time of subtotal thyroidectomy from twenty one patients with Graves' disease prepared for surgery with antithyroid drugs. There was no difference in TBII and TSAb activities between thyroidal and peripheral blood samples. These findings were regarded that while intrathyroidal lymphocytes are major site of thyrotropin receptor antibody (TRAb) production, similar levels are found in thyroidal and peripheral veins and that this in vivo study cannot exactly ascertain the TRAb producing site.

Osteoma is a benign osteogenic tumor composed of cancellous or compact bone, classified as peripheral, central, or extraskeletal. Peripheral osteomas are uncommon. Excluding the maxillary sinuses, the maxilla is a rare site for osteomas. The purpose of this report was to describe clinicopathological and radiological features of two peripheral osteomas occurring in the jaws, one located in the mandible and another in the edentulous maxillary alveolar ridge. The tumors were asymptomatic and were fully excised without any complications or recurrence. The lesions were submitted to histopathological analysis and diagnosed as peripheral osteoma, compact type.

Purpose: The aim of this study was to identify the effect of an observation window (OW) at peripheral intravenous (IV) catheter sites on early detection of IV infiltration among hospitalized children. Methods: This was a retrospective observational study with history control group design. Participants were children who had IV infiltration after peripheral catheterization when hospitalized from January to May, 2014 and January to May, 2015 at a children's hospital located in Yangsan city, Korea. The 193 patients, who were hospitalized from January to May, 2014 formed the control group and did not have OW, and the 167 patients, who were hospitalized from January to May, 2015 formed the window group and had OW. Data were analyzed using ${\chi}^2$-test, independent samples t-test and multiple logistic regression. Results: First stage IV infiltration was 39.5% for the window group and 25.9% for the control group, which was significantly different (p=.007). The likelihood of $2^{nd}$ stage and above IV infiltration decreased by 44% in the window group, which was significantly different (p=.014). Conclusion: OW at the peripheral IV catheter site was found to be an effective measure in early recognition of IV infiltration. Considering the effect of OW, we recommend that nurses should make an OW with transparent dressing during stabilization of the IV catheter site in hospitalized children in clinical settings.

As the large defect of peripheral nerve occurs, the autologous nerve graft is the most ideal method but it has many limitations due to donor site morbidities. Various materials have been developed for the nerve defect as the conduits, but none of these materials is satisfactory. Among them, $Gore-Tex^{(R)}$ tube seems to be one of the most ideal nerve conduit materials at peripheral nerve defect. Many researches have focused on finding the neurotrophic factors. It is recently demonstrated that Valproic acid(VPA) has an effect of axonal regeneration as a neurotrophic factor without enzymatic degradation and toxicity problems. The purpose of this study is to evaluate the effect of VPA on the nerve regeneration at the peripheral nerve defect. A 10 mm gap of rat sciatic nerve was made and $Gore-Tex^{(R)}$ tube filled with biceps femoris muscle was placed at the nerve defect site. We let the rat take VPA as drinking water in experimental group and did not give VPA to the control group. We estimated the results as electrophysiologic and histological aspects for 16 weeks after the surgery. The nerve conduction velocity, total myelinated axon count, myelin sheath thickness and mean nerve fiber diameter significantly increased in VPA-treated experimental group when compared to the control (p < 0.05). From the above results, we conclude that VPA promotes the nerve regeneration at the peripheral nerve defect site. It is suggested that $Gore-Tex^{(R)}$ tube filled with skeletal muscle and VPA administration may be a good substitute for autologous nerve graft.

To investigate the effects of exercise-training on serum lipids, fat distribution and several parameters of body fatness(percent body fat, skinfolds thickness, body circumference) were assessed in 24 healthy male subjects submitted to an 8-wk high intensive exercise-training. Blood sample was taken twice, per and post exercise-training, Exercise-training took place 5 days a week and daily energy intake and expenditure were observed. The results obtained are summarized as follows: 1) Through exercise-training body weight (changes : 1.1$\pm$1.1kg ; p=0.000) and percent body fat (changes : 2.4$\pm$1.3% ; p=0.000) decreased significantly . 2) Suprailiac was the most reduced site by exercise-training among eight site skinfolds. Central skinfolds were changed more by exercise-training than peripheral skinfolds with reduction of 1.7$\pm$1.7mm and 0.2$\pm$1.9mm. Central site circumferences were reduced more by exercise-training than peripheral site circumferences. 3) Total cholesterol, HDL-cholesterol and LDL-cholesterol were not significantly changed by exercise-training while only triglyceride decreased (changes : 20.7$\pm$44.8mg/dl ; p<0.05). Changes in body weight were grately related to changes in total cholesterol. Changes in deep abdominal adipose tissue were related to changes in triglyceride.

As online communities proliferate, online news sites have received great attention in news media research. Although most of the online news sites provide contents for free, some have adopted the Pay-What-You-Want (PWYW) model by offering a voluntary payment option to the readers. In this study, we investigate the factors which influence subscribers' voluntary payment behavior on an online news site. Drawing upon both the Stimulus-Organism-Response (SOR) framework and the Elaboration Likelihood Model (ELM), we hypothesize that appreciation has a direct effect on the subscribers' voluntary payment behavior, whereas central factors (positive emotional content, cognitive content) and peripheral factors (news sharing, news article length) of the news articles have indirect impacts on voluntary payment behavior through the enhanced appreciation. Based on an empirical analysis of 172 news articles from the Korean online news site that adopted the PWYW pricing model (i.e., Ohmynews.com), we find that appreciation plays a critical role in voluntary payment behavior and that peripheral factors have significant impacts on appreciation. However, the impacts of central factors on appreciation are not found. By identifying influencing factors of subscribers' voluntary payment behavior on online news sites for the first time, this paper suggests a prospective alternative profit model for online news providers faced with fierce competition.

Purpose: The purpose of this study was to evaluate the appropriateness of the replacement time intervals of 18 gauge peripheral intravenous catheters (PICs) by investigating the development of phlebitis. Methods: The subjects were 200 hospitalized patients over 18 yrs old aged who have 18 gauge PICs placed for surgery. After the insertion of PICs, the researcher monitored the insertion site daily for 96 hours for any signs of phlebitis. Results: Phlebitis developed in 25.7% of patients. Patients who developed phlebitis were significantly older and were receiving fluids with faster infusion rate. However, patients with and without phlebitis were not different by gender, insertion site, fluid osmolality, or pH of drugs administered. The incidence rate of phlebitis was higher than 10%(12.9%) starting 24~48 hours after the insertion of 18 gauge PICs. Conclusion: It is recommended to replace 18 gauge PICs within 24~48 hours after insertion. Close monitoring of the PICs insertion site for the signs of phlebitis is recommended.
