Objectives : The warm needling technique is the method combining the effects of acupuncture needle with those of moxibustion. We need to standardize the characteristics of the warm needling technique, in order to get more systematic and objective results in operation and effects and then get more clinical abilities in these fields. Methods : In this study, using labview system on the warm needling technique, we measured and compared partial temperature changes according to the kind of needle. We studied relations of moxa cones of various sizes with the peak combustion temperature. Results and Conclusions: When we measured the warm needling's partial temperature, temperature measured at 1 and 2 cm below the head, according to the kind of needle, gold needle got the higher result on the peak than SS304 stainless steel needle. In the case of combustion of the moxa cones, cones weighing 0.4 g and 0.8 g, respectively, and the apex ignition method with gold needle showed the higher result than the apex ignition method with stainless steel needle, when we measured the effective stimulus time at 2 cm below the head and the mean temperature during the effective stimulus time. Although more research to standardize the characteristics of the warm needling technique will be needed, we suggest, according to these results, that warm needling of gold needle combined with moxa cone of 0.4 or 0.8 g is effective.

"Watoji" is a Japanese traditional book binding technique. An aim of this research develops a support system which everyone can make Watoji easily by. This system uses a working situation by recognizing a position of a needle and annotating to a book directly by mixed reality technique. Additionally, a technique of recognizing a working situation at a book is sewn by a needle is proposed. The proposed system of recognizing a position of a needle is build, then we experiment recognizing of a needle from an image. Furthermore, setting up Watoji on the system, we experiment recognizing of a position of a needle. An experimental result shows recognizing a needle from an acquired image from a camera. Using this result, a working situation can be recognized. Then, suitable information to a working situation can be presented.

Background and Objectives : Surgery is considered the primary treatment for intracordal cyst. However, patients who had undergone surgery are still subject to recurrence and continued voice changes. Intracordal cysts naturally disappear in some patient population. Cyst does not always recur in patients who had received partial surgical removal, too. Contradicting results raises a question whether complete surgical removal of intracordal cyst is necessary and demonstrate need for better treatment. Herein, the author proposes novel surgical method technique intralaryngeal needle technique (INT), a technique using surgical needle for not only injection but also for aspiration and excision of cyst. This study aims to examine the potential of intralaryngeal needle technique in treating intracordal cysts. Materials and Methods : Surgical procedures were done on in-patients diagnosed with intracordal cyst. 23 patients received follow-up screening after the surgery for one year. Patients' subjective satisfaction levels, acoustic measures, aerodynamic measures, laryngeal stroboscopic results were compared before and after the treatment. Results : Overall patients were satisfied with novel surgical excision method. In terms of aerodynamic measures, maximum phonation time, mean air flow rate improved after the surgery. In terms of acoustic measures, Jitter, Shimmer, NHR, and voice pitch changes after the treatment showed statistically significant differences. Laryngeal stroboscopy results showed significant decreases in cyst sizes. Post-surgery patients had improved mucosal waves and amplitudes values. Conclusion : The results show the validity of intralaryngeal needle technique in reducing intracordal cyst size by excision, aspiration, and injection. The author believes this novel technique can be used as an alternative surgical method for intracordal cysts.

Background and Objectives : Laryngeal Evoked Electromyography(EEMG) is a objective, quantitative technique to determine innervation status of larynx. The possible applications of this technique are to confirm the etiology of impaired vocal fold motion and monitor perioperative vagus nerve trauma. The purpose of this study is to develop a novel method for determining the amount of reinnervation of recurrent laryngeal nerve with accurate, inexpensive, and minimally invasive technique in human. Materials and Methods : Laryngeal EEMG was performed for 16 adults with intact vocal folds motion and 2 patients diagnosed as unilateral vocal fold paralysis. for the purpose of searching what is the optimal and noninvasive technique for laryngeal EEMG, we used 2 types of stimulation configurations(transcutaneous vs percutaneous) and 2 types of recording configurations(intramuscular vs. surface). Results and Conclusions : Percutaneous needle stimulation and surface recording of laryngeal EEMG was reliable and comparable to standard needle stimulation and invasive intramuscular needle recording. But the laryngeal EEMG by the surface recording and transcutaneous surface stimulation was not reliable and repeatable. Therefore we recommended that laryngeal EEMG by surface recording and percutaneous needle stimulation would be minimally invasive, reliable technique to know the status of reinnervation in e patients with vocal fold paralysis.

In conventional percutaneous disc surgery, introducing instruments into disc space starts by inserting a guide needle into the triangular working zone. However, landing the guide needle tip on the annular window is a challenging step in endoscopic discectomy. Surgeons tend to repeat the needling procedure to reach an optimal position on the annular target. Obturator guiding technique is a modification of standard endoscopic lumbar discectomy, in which, obturator is used to access triangular working zone instead of a guide needle. Obturator guiding technique provides more vivid feedback and easy manipulation. This technique decreases the steps of inserting instruments and takes safer route from the peritoneum.

Background: We prospectively evaluated the incidence and possible factors causing intramuscular injection during lumbar sympathetic ganglion block and compared the multiple needle technique to the single technique to obtain a profound and complete block effect. Methods: Among 83 patients, 58 patients (group A, n = 27, multiple needle technique and group B, n = 31, single needle technique) were reevaluated for the changes of skin temperature (Ts) and mean segment of longitudinal contrast spread. After injecting the contrast agent, the incidence of psoas muscle injection and the change of Ts was compared between two groups. Results: The incidence of psoas muscle injection was 21.3% (46/216) and it was associated with the level of injection (L2) significantly (${\chi}_2$ = 14.773, P = 0.001). $DT^{post}$ (postblock temperature difference between ipsilateral and contralateral great toe, $4.6{\pm}2.8^{\circ}C$, $1.8{\pm}1.6^{\circ}C$, P < 0.001 for group A and B) and $DT^{net}$ ($DT^{post}$ - $DT^{pre}$, $3.9{\pm}2.7^{\circ}C$, $1.5{\pm}1.5^{\circ}C$, P < 0.001 for group A and B) was significantly higher in group A. The mean segment of longitudinal contrast spread was $8.1{\pm}0.9$ for group A and $3.2{\pm}1.6$ for group B (P < 0.001). Conclusions: The LSGB at the L2 level showed the lowest incidence of psoas muscle injection of contrast. Multiple needle approach showed more significant increase of $DT^{net}$ and $DT^{post}$.

A study .to identify an occupational hazards for hospital working health care providers from needle stick injury as an occupational hazards of health care providers in hospital and prevention A survey of 2430 health professionals (2184 nurses, 182 doctors, and 64 Lab technicians) was conducted to describe and provide information about 1) the experience of needle stick. 2) the number of needle stick, 3) the treatment after needle stick. 3) the situation of needle stick, 4) the report of needle stick, 5) the cause of needle stick, 6) the discard method of used needles, and 7) how to worry about getting infection disease after needle stick. Data were collected using questionnarires constructed by the authors and tested by a pilot study. Results of the study showed that 96.7% of the sample had an experience of needle stick (96.8% of the nurses, 96.7% of the doctors, and 92.2% of Lab technicians). Seventy seven percent of the sample experienced less than 10 needle sticks, 19% of the sample experienced 11 to 20 needle sticks, and the rest of the sample experienced more than 20 needle sticks. The situations where needle sticks occurred include intrvenous injection (36.5%), intramuscular injection (21.6%), blood withdraw (17.8%), and preparation(11.8%). The study showed that needle sticks (67.5%) usually occurred after client treatment. Health professionals used recapping method (55%) after they used needles. Needle sticks were predominantly caused by the carelessness of health professionals (61%), After needle sticks, 88.2% of the sample subjects treated needle sticks using disinfection technique by themselves. Most of health professionals (92.6%) did not report the accident. and 95.6% of them did not receive any test or further treatment. After needle sticks, 87.8% of nurses, 83.6% of doctors, and 96.6% of lab technicians worried about hepatitis infection. 'Health professionals also worried about AIDS infection, tetanus, venereal infection, and skin injury. These findings suggest that health professionals are at high-risk of needle stick and fail to report needle stick accidents. They should pay more attention to needle stick in order to avoid unwanted infection.

Background: Authors modified the traditional continuous axillary brachial plexus block technique of Selander for purpose of increasing success rate and decreasing complications by use of commercial epidural anesthesia set. Method: Thirty-nine patients scheduled for upper extremity operations were injected with 40 ml of anesthetic solution by axillary perivascular technique, using 23~25G immobile needle at 2 cm from the pectoralis major. Tuohy needle was immediately introduced at 4 cm from the pectoralis major and pierced the expanded neurovascular sheath at an angle of 30 degree to the skin. The "pop" was well noted well. Needle was advanced 0.5 to 3.0 cm and epidural catheter introduced through the needle. After removal of needle, occlusive dressing was done. Tip of catheter and spread of solution were demonstrated by fluoroscopy with contrast dye after completion of procedure. Result: Catheter insertion was successful at first attempt for all case. Total length of insertion was from 6 to 13($10.0{\pm}1.7$) cm. Tip of catheter was placed in infraclavicular space(66.7%), about the humeral head(17.9%) and in upper arm in 3 cases as U-shape(7.9%). Catheters were maintained for $6.7{\pm}2.6$(3-12) days. There were no complications such as: perforation of major vessels, needle trauma to nerve, infection, bleeding or hematoma. Conclusion: This study demonstrated continuous axillary brachial plexus block with epidural anesthesia set is safe, easy and convenient modification of technique of Selander.
