Purpose: The aim of this study was to evaluate the effectiveness of ultrasound-guide steroid injection according to Morton's neuroma size. Materials and Methods: From October 2008 to September 2011, 17 patients (23 cases) diagnosed with Morton's neuroma were investigated. All cases were female and mean age was 52.6 years old. Neuroma were measured by the horizontal and longitudinal length of the mass and underwent ultrasound-guided steroid (5 mg dexamethasone) injection. The efficacy of the injection was determined by Visual Analogue Scale pain score and patient satisfaction(subdivided 4 group-much improved, improved, not improved, aggrevation) Results: 7 of 23(30.4%) cases showed much improved and improved satisfaction and mean longitudinal and horizontal length were $0.71{\pm}0.39cm$ and $0.47{\pm}0.24cm$, respectively. 16 of 23(69.6%) cases showed not improved and aggrevation satisfaction and mean longitudinal and horizontal length were $0.83{\pm}0.42cm$ and $0.54{\pm}0.14cm$, repectively. There was a significant difference in VAS and patient satisfaction in case longitudinal and horizontal length were smaller than 0.5 cm and 0.4 cm. (p<0.05) Conclusion: The ultrasonography is a important modality in diagnosis and treatment of morton's neuroma. Ultrasound-guide steroid injection is effective in case longitudinal and horizontal length were smaller than 0.5 cm and 0.4 cm, respectively.

Purpose: Reconstructive surgeries for equinocavovarus foot deformities are quite variable, including hind-midfoot osteotomy or arthrodesis, soft tissue procedure, tendon transfers, etc. Comprehensive evaluation of the deformity and its etiology is mandatory for achievement of successful deformity correction. Few studies in this field have been reported. We report on the clinical and radiographic outcome of reconstruction for cavovarus foot deformities. Materials and Methods: The study is based on 16 feet with cavovarus foot deformities that underwent bony and soft tissue reconstructive surgery from 2004 to 2008. We evaluated the etiologies, varieties of surgical procedures performed, pain score, functional scores, and patient satisfaction and measured the radiographic parameters. Results: The average age at the time of surgery was 39.4 years old, with a male/female ratio of 9/4 and an average follow-up period of 23.9 months (range, 12~49 months). The etiologies of the cavovarus deformity were idiopathic 7 feet, residual poliomyelitis 5 feet, Charcot-Marie-Tooth disease 2 feet, and Guillain-Barre syndrome and hemiplegia due to cerebrovascular accident sequela 1 foot each. Lateral sliding calcaneal osteotomies were performed in 12 feet (75%), followed by Achilles tendon lengthening and plantar fascia release in 11 feet (69%), and first metatarsal dorsiflexion osteotomy/arthrodesis and tendon transfer in 10 feet (63%). Visual analogue scale pain score showed improvement, from an average of 4.2 to 0.5 points. American Orthopaedic Foot and Ankle Society ankle-hindfoot score showed significant improvement, from 47.8 to 90.0 points (p<0.05). All patients were satisfied. Ankle range of motion improved from $27.5^{\circ}$ to $46.7^{\circ}$. In radiographic measurements, calcaneal pitch angle improved from $19.1^{\circ}$ to $15.8^{\circ}$, Meary angle from $13.0^{\circ}$ to $9.3^{\circ}$, Hibb's angle from $44.3^{\circ}$ to $37.0^{\circ}$, and tibio-calcaneal axis angle from varus $17.5^{\circ}$ to varus $1.5^{\circ}$ Conclusion: We achieved successful correction of cavovarus foot deformities by performing appropriate comprehensive reconstructive procedures with improved functional, radiographic measures and high patient satisfaction.

A foot pedal switch in the diagnosis x-ray radiography system has been researched to improve radiologic technologist works and patient satisfaction. The switch has been installed in the diagnosis x-ray radiography system used in domestic clinics. Quantitative evaluation has been conducted by measuring the exposure dose reproducibility test, tube voltage, mAs, and percentage average error. Qualitative evaluation has been conducted by analysis of the radiologic technologists questionnaire. In the quantitative evaluation for the use of the foot pedal switch, the coefficient of variation was less than 0.05 in the exposure dose reproducibility test. In the mAs test, percentage average error of ${\pm}20%$ was measured. There was no problem raised since it meets the all inspection standards of the diagnosis x-ray generator. In the qualitative evaluation, most of the opinions are that it has a clinical value for the foot pedal switch in the diagnosis x-ray radiography system. Therefore, developing the foot pedal switch for the diagnosis x-ray radiography system can improve effectively the rapidity and accuracy of the radiologic technologist work. In addition, it is effective in decreasing the x-ray exposure of patients and increasing satisfaction for the medical service due to reduction of retaking x-ray.

Background: It is difficult to treat tourniquet-induced hypertension despite adequate anesthesia, and the mechanism of that is not known. And it may be possible that intraoperative continuous infusion of opioid induces preemptive analgesia postoperatively. We investigated the effect of intraoperative continuous i.v. fentanyl on tourniquet induced cardiovascular changes and postoperative preemptive analgesia in total knee replacements. Methods: Sixty patients were randomly assigned to two groups; In study group ($1.5{\mu}g/kg$ loading and $0.5{\mu}g/kg/hr$ continuous infusion of fentanyl before skin incision and tourniquet inflation) and control group (no treatment). Anesthesia was maintained with enflurane (1-2 MAC) and 50% nitrous oxide in oxygen. Arterial pressure and heart rate were compared between two groups. They received postoperative pain treatment with patient-controlled analgesia (PCA) with fentanyl during the postoperative 48 hours after total knee replacement. Visual analog scale (VAS) scores at either rest or movement were used to assess pain. Total fentanyl dose delivered, number of PCA requests, supplemental analgesics, overall satisfaction score and adverse events were evaluated. Results: There were no significant differences between the two groups on cardiovascular changes by tourniquet induced pain effect. VAS, PCA delivered dose and PCA demands at movement in the 24-48 hour decreased in study group compared with control group (P < 0.05). But there were no significant differences between the two groups on the other time periods except 24-48 hour's patient satisfaction and adverse events. Conclusions: We suggest that intraoperative continuous i.v. fentanyl infusion dose not affect cardiovascular change by tourniquet induced pain. But it may induce preemptive analgesia postoperatively.

The purpose of the study are expected to provide some basic information on counseling, diagnosis and treatment planning for patients related to teeth care. A self-reported questionnaire was filled out by 320 subjects in Seoul and Gyeonggi from May to August, 2015 after permission from Institutional Review Board (IRB). Except 18 copies, 302 data were analyzed using SPSS WIN 19.0 program. The questionnaire consisted of four questions of the general characteristics of the subjects, ten questions of the awareness toward of subjective teeth, five questions of the influence of teeth on appearance, and ten questions of self-esteem. The dependent variables made a 23.4% prediction of self-esteem. If they have higher education(p<0.001), influence of teeth on appearance(p<0.001) and the awareness toward of subjective teeth(p<0.001) had significant influence on self-esteem. The findings suggest that heightened subjective awareness toward teeth seems to be of use for the improvement of self-esteem. Therefore it's required to make an effort to take good care of teeth in terms of color or arrangement as well as oral health.

Patient-Controlled Analgesia (PCA) has been widely used for postoperative pain relief. Meperidine is useful for PCA and has efficient analgesia, rapid onset, and low incidence of adverse effect. To compare the analgesic effect, total dose and hourly dose, side effect and neonatal status of breast feeding with meperidine via intravenous or epidural PCA for 48 hours after Cesarean Section, 40 parturient women undergoing elective Cesarean Section were randomly divided into two groups. Each respective group of 20 parturient women received meperidine via one of the intravenous PCA after general anesthesia with enflurane (IVPCA group) and the epidural PCA after general anesthesia with enflurane (IVPCA group) and the epidural PCA after epidural block with 2% lidocaine 20ml combined with general anesthesia with only $N_2O$ and $O_2$ (EpiPCA group) when they first complained of pain in recovery room. Following the administration of analgesic initial dose, parturient women of IVPCA group were allowed intravenous meperidine 10 mg every 8 minutes when they felt pain. The EpiPCA group received additional bolus dose of meperidine 2 mg and bupivacaine 0.7 mg were administered every 8 minutes as requested the patients with hourly continuous infusion of meperidine 4 mg and bupivacaine 1.4 mg. Data was collected during the 48 hours observation period including visual analog scale (VAS) pain scores, total meperidine dose, hourly dose during 48 hours and each time interval, incidence of adverse effect, satisfaction, and neonatal status with breast feeding. VAS pain scores of analgesic effect in EpiPCA group was significantly lower than in IVPCA group at 2 hours after the initial pain after Cesarean Section. Total dose and hourly dose of meperidine significantly reduced in EpiPCA group. Hourly dose of meperidine at each time interval significantly reduced during first 6 hours and from 12 hours to 24 hours in EpiPCA group. The side effects in IVPCA group were mainly sedation, nausea, and local irritation of skin. And EpiPCA group experienced numbness and itching. The degree of satisfaction of parturient women was 88.2 % in IVPCA group and 85.7 % in EpiPCA group. We did not observe any sedation, abnormal behavior, or seizure like activity in any neonates of breast feeding. From the above results we conclude that epidural PCA was more efficiently analgesic, less sedative, and consumptional, and safer for neonate than intravenous PCA, and could be an alternative method to intravenous PCA.

Purpose: We wanted to compare the accuracy between the blind anterior approach and ultrasound guided posterior approach, which are preferred in the present clinical practice for the glenohumeral joint injection. Materials and Methods: The consecutive 95 cases were included in that the glenohumeral joint injection was done in the university hospital and the medical record and ultrasonography were available. There were 52 cases which were injected by blind anterior approach (group I) and 43 cases who were injected by ultrasound guided posterior approach (group II). The injection was decided as accurate if the fluid was visualized in the posterior joint under the ultrasound. We evaluated the range of motion before and after 2 weeks of injection. A subjective satisfaction of the patients was interviewed at the 2 weeks after injection. Results: The accuracy of the glenohumeral joint injections of the group I and group II was 80.8% and 90.7%, respectively. The range of motion was improved for the all cases regardless of the approaches. At the 2 weeks after injection, the subjective satisfaction (better than good) was achieved in 73.7%. Conclusion: The accuracy of the blind anterior approach for the glenohumeral joint injection was 80.8%. The accuracy of the ultrasound guided posterior approach was 90.7%. In this comparative study by the one physician, the ultrasound guided posterior approach showed the better accuracy.
