Purpose: This study was aimed to assess TLE1 as a target molecule of synovial sarcoma. Method: We obtained tissue samples and clinical data from 36 patients who were diagnosed and treated for synovial sarcoma in our hospital. Immunohistochemical staining was performed to detect the expression of TLE1 in synovial sarcoma and normal tissues such as fat, skeletal muscle, peripheral nerve, vascular endothelium, and epithelium. Univariate survival analysis was performed to find whether overexpression of TLE1 is correlated to poor prognosis. Results: TLE1 was expressed in 35 (97%) cases (grade 1 was 5 cases, grade 2 was 28 cases, grade 3 was 2 cases.). Normal tissues from mesenchymal origin did not express TLE1. However, epithelial and endothelial cells showed weak expression (grade 1) of TLE1. The level of TLE1 expression did not have any prognostic significance according to univariate survival analysis. Conclusion: TLE1 may be a new molecular target of synovial sarcoma that differentiates synovial sarcoma from normal mesenchymal cells.

Purpose: We evaluated the correlation of the anatomic parameters of the acromion those represent on the magnetic resonance image (MRI) of impingement syndrome. Materials and Methods: From June, 2004 to December, 2005, 71 cases were surgically proven to be impingement syndrome, and the anterior acromial hooking angle, the lateral acromial hooking angle (AAHA and LAHA) and the acromial hooking index (AHI: the sum of the AAHA and LAHA) were compared to 16 control cases. At the same period, 55 cases were surgically proven to be partial or full thickness rotator cuff tear, and age, gender and twelve anatomic parameters, including the acromial type, the acromial angle, the anterior covering, the acromial slope, the AAHA, the lateral acromial angle, the acromial torsional angle, the lateral acromial angulation, the LAHA, the lateral covering, the acromiohumeral distance and the AHI were assessed. Results: The AAHA and AHI were increased as impingement syndrome proceeded. The acromial type and acromial angle, and the AAHA, LAHA and AHI showed significant differences between the controls and the rotator cuff tear patients on univariant analysis. On multivariant analysis, gender was most strongly correlated with rotator cuff tear. Age, AAHA and the acromial angle showed similar correlation, respectively. Conclusion: The coronal acromial shape is correlated with rotator cuff tear, and it is important to correct the lateral acromial shape when performing acromioplasty.

Purpose: We aim to determine sciatic nerve bifurcation location and depth at the level of the popliteal fossa in Korean female. Materials and Methods: Thirty three subjects were enrolled in Korean female. M-turbo ultrasound system (SonoSite, bothell, WA, USA)with 38 mm high frequency linear array transducer, 13-6 MHz probe was used for ultrasound measurements. With subject lying prone, the location of the sciatic nerve in relation to the popliteal crease and skin to nerve distance were assessed via ultrasound. Analyses were performed with SAS version 9.3 using multiple linear regression. Results: Thirty three subjects were enrolled. Distance from the popliteal crease to the sciatic nerve was 4.5-7.5 (mean 5.7 cm), and the depth of the sciatic nerve from the skin was 1.8-3.2 (mean 2.4 cm). Multiple linear regression for the usefulness of the model has a p value of 0.036, shows between weight and depth. Conclusion: We show that variability exists for sciatic nerve bifurcation location in Korean female, The success rate is creased if consider the relations between weight and depth when performs sciatic nerve block in Korean female. In our study, a sciatic nerve block is recommend that performed 7.5 cm proximal to the crease in the popliteal fossa.

This report describes a variation of the tendinous slip of the flexor digitorum longus (FDL) for the great toe. In addition, compositions of the long flexor tendons for all five toes were examined. The tendons of the FDL in the foot were investigated in 66 specimens of embalmed Korean adult cadavers. The tendons of the flexor hallucis longus (FHL) and the FDL with the lumbrical muscles were cut at the calcaneus and the metatarsophalangeal joints and were removed en bloc specifically to observe the FDL and the FHL tendons of the great toe. The tendinous slip of the FDL for the great toe was found bilaterally in the foot of a 52-year-old male. Its prevalence was two of 66 specimens (3.0%). The tendinous slip of the FDL for the great toe passed forward the great toe, and it constituted the superficial portion of the long flexor tendon for the great toe. The tendon of the FHL passed forward to constitute the deep portion of the long flexor tendon for the great toe. Thus, both the tendinous slip of the FDL and the tendon of the FHL composed the long flexor tendon for the great toe. The tendinous slip of the FDL and the tendon of the FHL for the great toe were similar in thickness; thus, each tendinous slip of the FDL and the tendon of the FHL were approximately one-half of the long flexor tendon for the great toe in thickness. The present study demonstrated an anatomical variation of the interconnection between the FHL and the FDL tendons, which will be useful for various surgeries and biomechanical research.

Objectives The purpose of this study was to verify the effect of integrative Korean medicine on acute postoperative pain after arthroscopic shoulder surgery. Methods This study was conducted in a retrospective observational way. Patients who met the inclusion criteria were divided into integrative Korean medicine-treated group (IKM group) and no integrative Korean medicine treated-group (No IKM group). The primary outcome was the difference in the amount of change in pain intensity. The secondary outcome was the difference in pain intensity, opioid consumption over time, and the number of adverse events after surgery. Results The change of numerical rating scale for pain intensity from baseline to IKM group was 3.09±2.12, while 2.64±1.80 in no IKM group, and the difference of change between two groups was statistically significant (p<0.05). Difference in the use of opioid between two groups over time after surgery was also statistically significant (p=0.000). Conclusions The results of this study suggest that integrative Korean medicine can be effective for acute postoperative pain after arthroscopic shoulder surgery.

Breast cancer related lymphedema (BCRL) is one of the most intractable complications after surgery. Patients suffer from physical impairment, as well as psychological depression. Moreover, a recent study revealed that cellulitis significantly increased the risk of BCRL, and cellulitis has been suggested as a risk factor of BCRL development. We describe a patient treated with stellate ganglion blocks (SGBs) without steroid for relief of symptoms and reduction of the arm circumference of breast cancer-related infectious lymphedema in a month. We measured the arm circumference at four locations; 10 cm and 5 cm above and below the elbow crease, numeric rating scale (NRS) score, lymphedema and breast cancer questionnaire (LBCQ) score on every visit to the pain clinic. A serial decrease of the arm circumference and pain score were observed after second injection. In the middle of the process, cellulitis recurred, we performed successive SGBs to treat infectious lymphedema. The patient was satisfied with the relieved pain and swelling, especially with improved shoulder range of motion as it contributes to better quality of life. This case describes the effects of SGB for infectious BCRL patients. SGB could be an alternative or ancillary treatment for infectious BCRL patients.

Purpose: The aim of this study is to investigate the characteristics of patients and teeth referred to a university dental hospital for endodontic problem. Materials and Methods: From January, 2017 to December, 2018, patients who were referred to a university dental hospital for endodontic problem were collected from clinical records. A total of 1171 patient records were analyzed. The status of the referred teeth was divided into three groups according to whether they were treated endodontically based on radiographs and clinical records at the time of referred visit. Results: 69.9% of the referred teeth were maxillary and mandibular first and second molars. The average time from referral to actual visit is 9.03 days and 65.6% of the case referred with referring letter. The most primary reasons of referral were persistent clinical symptom (pain, swelling, and sinus tract) (37.9%), diagnosis difficulty (16.7%), blockage of canal space (13.8%) and difficult tooth anatomy (11.4%). In the case of referral before endodontic treatment, the most primary reason of referral was failure to make a proper diagnosis. If the teeth were referred in the middle of endodontic treatment, the most primary reason of referral was persistent clinical symptom and blockage of canal space. In the case of referral after root canal filling, the most primary reason of referral was persistent clinical symptom. Conclusion: In the case of molars, the rate of persistent clinical symptom and blockage of canal space were the most primary reason of referral, and the rate of apical surgery and management of trauma was high in the case of anterior teeth.

This study is a systematic review of randomized experimental and non-randomized studies on the effects of lavender scent therapy on pain and a meta-analysis to provide evidence-based data. The data included in the meta-analysis are 18 studies published from 2000 to 2018, with interventional subjects being surgical, maternal, arthritis and dialysis patients, and the types of interventions were massage, application, hot-pack, and taking medication. RESULTS: The effect size (Hedges' g) for pain was -0.16 [95% CI:-1.40: -0.72], which was statistically significant. The effect size according to intervention type was -1.36 [95% CI: -1.96, -0.77], local application -1.11 [95% CI:-1.57-0.66], inhalation -1.05 [95% CI:-1.54, -0.56 ], and massage -0.92 [95% CI:-1.62, -0.23], all of which were statistically significant. To explore the possible causes of heterogeneity ($I^2=88%$), meta-ANOVA was conducted with covariates of intervention type or study design, and the results revealed it was statistically insignificant (intervention type Q=0.25, df=3, p=.968, study design Q=0.22, df=1, p=.642).

To use the external connection implant (EXT) appropriately, the inter-implant distance should be carefully considered during placement, and the bones raised above the implants should be trimmed during the second surgery. The hex abutment is more useful than the non-hex abutment. EXT is particularly useful when the inter-arch space is limited. The tissue level (TL, internal butt connection) implant has a biomechanical advantage of coronal wall thickness and a biological advantage of an inherent transmucosal smooth surface. During TL implant restoration, an abutment can be selected using the abutment and fixture margins with considerations for the inter-arch space. Since no single type of implant can satisfy all the cases, it is necessary to select the appropriate type, considering the occlusal force and the bone condition.

This study investigates the effect of wrist guards equipped with electronic muscle stimulation on reducing wrist pain and improving wrist function of actual lure fishing participants. This study combined conductive fabrics by selecting two products of wrist guards that can be used in lure fishing, which requires holding fishing rods with hands for a long time. It was conducted on ten healthy men aged 35 to 45, and the selection conditions were selected for those who did not have a history of surgery on the wrist and are currently enjoying lure fishing as a hobby. The experimental movement was performed 100 times before each experiment to cause delayed muscle pain to cause wrist fatigue when lure fishing was performed with the operation of grip strength and range of motion. As a result of this study, it was found that pain reduction, range of motion, and grip strength were improved when electrical stimulation was applied after wearing a wrist band in the form of a wrist wrap and semi-gloves. The conclusion of this study was that when electrical stimulation was applied to the wrist guards, the effect of improving the fatigue and function of the wrist could be confirmed through experiments. Through this study, it is expected that wearing electronic muscle stimulation wrist guards will have a significant effect on preventing wrist injuries and improving functional recovery for lure fishing participants.
