The aim of this study was to evaluate the efficacy of a topical 0.2% hyaluronic acid (HA) preparation in the management of wound after removal of arch bar for facial bone fracture and a suture site after orthognatic, oral cancer or oral surgery. Forty patients participated in a randomized, placebo controlled, double-blind trial to evaluate the efficacy of the topical HA and preparation. HA topically applied to the wound after removal of arch bar or stitch out, 3 times a day for 4 weeks. Evaluation is performed once a week for 4 weeks. For subjective evaluation, relative pain reduction in visual analog scale (VAS) and existence of heat sensation was accessed. For objective evaluation, gross evaluation, papilla index, existence of wound dehiscence, redness and swelling was checked. The same evaluation was performed in each arch bar group and suture group. For whole subject, 0.2% HA group resulted higher reduction than placebo group in pain of site in first week with significancy. Same findings were seen other weeks but there was no significancy. 0.2% HA group had better result than placebo in objective evaluation (papilla index, wound dehiscence, redness and swelling), but in gross evaluation placebo had better result than 0.2% HA group with no significancy. Subject was divided into suture group and arch bar group. Same aspect was seen, but only suture group had significancy not arch bar group in pain reduction score. 0.2% HA group resulted higher reduction than placebo group in pain of site in first week with significancy, especially in suture group. It reveals topical application of HA in wound especially suture site reduced pain in early stage. And 0.2% HA group had better result than placebo in papilla index, redness and swelling with no statistical significancy. In conclusion, HA has effect of pain reduction and healing promotion in the mucosal wound after oral surgery.

In order to evaluate the effect of conservative treatment for Temporomandibular Disorders(TMD), 137 patients were subjected at the Department of Oral Medicine, Pusan National University Dental Hospital from June 2012 to Sept. 2012. They were treated conservatively with behavioral therapy, physical therapy, medication and occlusal stabilizing splint therapy. Subjective symptoms and clinical findings were investigated to evaluate and compare the patients' status after 3 months treatment. The results were as follows; 1. Pain, Noise, LOM(Limitation of motion) and MCO(Maximum comfortable opening) measurements of TMD were markedly improved after conservative treatments including behavior therapy, physical therapy, medication and splint therapy. 2. There was no difference in treatment outcomes after conservative treatments when the subjects were classified and compared according to gender and chronicity. 3. Conservative treatment including stabilization splint produced better results than physical therapy with medication. 4. After 3 months of treatment, pain and LOM were significantly improved in the MD(Muscle disorder) group. Pain, LOM and noise were significantly improved in the DD(Disc displacements) group. In the OA(Osteoarthritis) group, pain, noise, LOM and MCO were significantly improved.

Purpose: The purpose of this study is to evaluate diagnosis and treatment of acetabular labral tears in sports injuries. Materials and Methods: From March 1995 to January 2000, We treated 15 patients with acetabular labral tear by sports injuries. There were 6 men and 9 women. Mean age was 41 years old. Running injuries are 5 cases, fighting 3, aerobic exercise 3, swimming 2, climbing 1, bicycle 1. For conservative treatment, we performed medication and observation at least for 1 year. For the patients with arthroscopic surgery, we performed Harris Hip Score (pain and function) preoperatively and postoperatively at 6, 12 months, and evaluated patient’s pain by JOA pain scoring system and postoperative subjective satisfaction. Results: The mean score of HHS improved 15 points with conservative treatments and 32 points with hip arthroscopy. In 4 cases of conservative treatment, there was 1 scale improvement of JOA pain scoring system. In arthroscopic partial labrectomy, all cases were improved to more than 2 scale. Conclusion: We considered that acetabular labral tears occurred associated with sports injuries. So it is important to be interested in enthusiastic diagnosis and appropriate treatment for hip pain caused by sports injuries, especially about acetabular labral tears.

Background: Intraosseous anesthesia (IO) allows the anesthetic solution to be injected directly into the cancellous bone. The anesthetic solution immediately reaches the periapical region, and thus the axonal area of the nerve, where it can temporarily disable the sodium pump. The effect is felt almost without any time delay, and only a small amount of anesthetic solution is required. Methods: This study aims to investigate the efficacy of IO using the AnestoⓇ device after infiltration anesthesia (IA) and/or inferior alveolar nerve block anesthesia (IANB) failed to work in symptomatic irreversible pulpitis (hot tooth). The 33 patients included in the study were treated additionally with 1.7 ml articaine hydrochloride with 1:100,000 epinephrine hydrochloride (UltracainⓇ D-S, Sanofi-Aventis, Frankfurt, Germany) IO. Results: The electrical pulp test showed that 95.76% of the volunteers reacted positively to the combination of IANB or IA with the IO. In women, the additive IO was effective at 97.22%. In men, the IO led to pain elimination in 94.00% of cases. The duration of the IO was less than a quarter of an hour (13.03 min). The IO worked longer in women than in men (13.61 min vs. 12.33 min). Overall, more than every third tooth that needed trepanation was located in the posterior area of the mandible (36.4%). Treatment of hot teeth in this area was associated with an increased pulse rate and increased residual pain. There was a moderate correlation (Spearman-Rho [IRI] = 0.280) between the Visual Analog Scale (VAS) score and bone density, and a significant correlation (IRI = 0.612) between subjective residual pain and bone width. The IO resulted in a moderate, transient increase in the pulse rate by approximately 20 bpm. This is similar to the temporary increase in heart rate after conventional anesthesia techniques in non-preloaded patients and can be considered clinically irrelevant. Conclusion: IO with the AnestoⓇ device as an extension and deepening of local pain elimination is recommended for the treatment of hot teeth.

In modern society, the amount of information has been significantly increased according to the development of Internet and IT convergence technology and that leads to develop information obtaining and searching technologies from lots of data. Although the system integration for medicare has been largely established and that accumulates large amounts of information, there is a lack of providing and supporting information for nursing activities using such established database. In particular, the judgement for the intervention of pains depends on the experience of individual nurses and that leads to make subjective decisions in usual. In this paper, a pain nursing supporting method that uses the existing medical data and performs collaborative filtering is proposed. The proposed collaborative filtering is a method that extracts some items, which represent a high relativeness level, based on similar preferences. A preference estimation method using a user based collaborative filtering method calculates user similarities through Pearson correlation coefficients in which a neighbor selection method is used based on the user preference.

From the environmental adaptation point of view, the clothing habits made by the thermal sensation and clothing weight of elderly women have changed according to the thermal sensation and health condition. The purpose of this study was to obtain the basic data for developing healthy and comfortable clothing for elderly women. Clothing weight, thermal sensation, clothing microclimate, resistance to cold and heat of 198 elderly women in Taejeon were surveyed from October 9, 2007 to October 19, 2007. 1. Clothing weight per body surface area was $830.4g/m^2$ of total clothing weight, $242.8g/m^2$ of underwear clothing weight, $617.3g/m^2$ of outerwear clothing weight, $419.8g/m^2$ of upper clothing weight, and $420.4g/m^2$ of lower clothing weight. 2. More than 90% of the respondents replied that they felt comfortable when the temperature inside the clothing was $33.5^{\circ}C$ and humidity inside the clothing was 30.2%. 3. The elderly women were more sensible to cold than to hot, those who felt cold had a tendency to wear heavier clothing. 4. The appeal rate for physical pain of older and lower income people, especially those with an income under 1,000,000 won, was higher than that of others. On the other hand, the lower the subjective economic level, the younger they were, and the more the monthly average income was, the higher the rate of mental pain. 5. The heavier the total clothing weight was, the higher the appeal rate for general pain.

Purpose: Leg elevation is known as an effective method for reducing leg swelling, and it has been routinely used in medical practice. However, the effect of swelling reduction in relation to the degree of elevation height is not known. This study evaluated the swelling of the leg after acute ankle fracture operations at two different elevation heights and the elevated leg heights were compared. Materials and Methods: A total of 66 patients with postoperative acute ankle fractures were classified into two groups depending on the presence of different leg elevation heights: high-elevated (HE, case) and low-elevated groups (LE, control). We checked leg swelling, pain, subjective satisfaction for the elevation device, and the American Orthopedic Foot and Ankle Society (AOFAS) score, and we retrospectively compared them between both the groups. Results: Leg swelling and pain were reduced in both groups. However, they did not show any significant differences between both the groups (p>0.05). Nineteen patients in the HE group replied with uncomfortable, while no patients in LE group did so. The AOFAS score at 1 year postoperatively did not show any significant differences between both the groups (p=0.46). Conclusion: High elevation of the leg after ankle fractures did not show a significant difference from low elevation in regard to leg swelling, pain, and function. Furthermore, high leg elevation resulted in discomfort during the postoperative period. Thus, low elevation with a pillow is enough for acute ankle fracture patients with little discomfort and satisfactory swelling reduction.

Purpose: The purpose of this study was to identify the effect of hand acupuncture on reduction of headache. Method: This study used a quasi-experimental pre-test and post-test design. 45 middle school girls who complained of headache were selected as subjects. The study lasted from November 2002 to June 2003. There were 22 girls in the experimental group while 23 girls were control group; convenience assignment was used. The two groups were homogeneous on characteristics. The experimental group received hand acupuncture. The treatment was to puncture corresponding points (A33, B27, M1, I2) on both the palm and the back of a hand with disposable acupuncture needles, and then remove them after a 20-30 minutes recess during which the subjects reclined on a bed. The data were analyzed using the SPSS PC with Fisher's Exact -test, and Mann Whitney U-test. Result: The results of this study were as follows: 1) In the experimental group, objective pain decreased after hand acupuncture (U= -2.51, p= .01). As for the objective pain degree, a significant reduction in voice change was observed in the experimental groups (U= -2.35, p= .02). Facial expressional changes were observed (U= -1.87, p= .06) and perspiration degree (U= -.99, p= .32) has reduced. However, these differences were not statistically significant between the experimental and control group. 2) Subjective pain degree decreased after hand acupuncture in the experimental as compared to the control group. 3) No statistical significant difference in comfort (U= -.29, p= .78) or distress (U= -1.51, p= .13) between experimental and control group were found. Conclusion: These findings indicate that hand acupuncture is an effective method for reducing headache. Therefore, hand acupuncture can be considered as an independent nursing intervention for headache reduction.

Background: To improve muscle flexibility, static stretch is the most common type and is considered safe and effective for improving overall flexibility of muscles. During the stretch, the intensity is more likely to be determined by the degree of an athlete's pain and practitioner's skills rather than quantitative measures of stretch. It is necessary to determine the optimal intensity for the stretch. Objects: The purpose of this study is to explore the relationship between hand held dynamometer (HHD) and verbal rating scale (VRS) in comparison of the effects of continuance time on active (walking) and inactive (sitting) movement after static stretch. Methods: A cross-sectional study was conducted with a sample (n=62) recruited from a university. Participants were randomly assigned to 2 different groups (n=31 for each group) based on participants' positions either remaining in sitting or freely walking around for a series of re-assessments. Data was collected at pre-warm up, pre-stretch, post-stretch, and additional assessments at the time of 3, 6, 9, 12, 15, 20 and 30 minutes after the stretch. Results: Relationship between VRS and HHD scores represents very weak correlation (Spearman's p=-.16, p>.05). Pearson's correlation analysis was conducted following the logarithmic transformation of the two scores. Pearson's correlation after the transformation still showed a very low relationship and a poor linear relationship between the two scores (Pearson's r=-.18, p>.05). Conclusion: The optimal intensity for stretch cannot be solely determined by the subjective pain perception. The objective measurement such as HHD could be used in conjunction with the pain perception.
