Abstract
BACKGROUND Microwave endometrial ablation (MEA) is a minimally invasive treatment for menorrhagia. It has been covered by the national insurance in Japan since April 2012, and its demand has been increasing as the importance of women's health has advanced in society. AIM To examine the efficacy of MEA as a treatment option for menorrhagia. METHODS In this study, we retrospectively analyzed 76 patients who underwent MEA between January 2016 and March 2020 in our department. MEA was performed in the lithotomy position, under general anesthesia, and with transabdominal ultrasound guidance, including the entire endometrial circumference while confirming endometrial coagulation. The Microtaze AFM-712 and the Sounding Applicator CSA-40CBL-1006200C were used for MEA, and the endometrium was ablated using a Microtaze output of 70 W and coagulation energization time of 50 s per cycle. The visual analog scale (VAS) was used to evaluate menorrhagia, menstrual pain, and treatment satisfaction. Additionally, the hemoglobin (Hb) levels before and after MEA and associated complications were investigated. RESULTS The average age of the patients was 44.8 ± 4.0 years. While 14 patients had functional menorrhagia, 62 had organic menorrhagia, of whom 14 had endometrial polyps, 40 had uterine fibroids, and 8 had adenomyosis. The VAS score before MEA and 3 and 6 mo after the procedure were 10, 1.3 ± 1.3, and 1.3 ± 1.3, respectively, for menorrhagia and 10, 1.3 ± 1.8, and 1.3 ± 1.8, respectively, for menstrual pain, both showing improvements (P < 0.001). The MEA Hb level significantly improved from 9.2 ± 4.2 g/dL before MEA to 13.4 ± 1.2 g/dL after MEA (P = 0.003). Treatment satisfaction was high, with a VAS score of 9.6 ± 0.7. Endometritis was observed in one patient after surgery and was treated with antibiotics. CONCLUSION MEA is a safe and effective treatment for menorrhagia.

Abstract
BACKGROUND Laparoscopic sacrocolpopexy for pelvic organ prolapse (POP) is a new and widely used approach; however, ever since the United States Food and Drug Administration warned against the use of surgical mesh, repairs performed using patients’ tissues [i.e. native tissue repair (NTR)] instead of mesh have attracted much attention. At our hospital, laparoscopic sacrocolpopexy (the Shull method) was introduced in 2017. However, patients with more severe POP who have a long vaginal canal and overextended uterosacral ligaments may not be candidates for this procedure.
AIM To validate a new NTR treatment for POP, we examined patients undergoing laparoscopic vaginal stump–round ligament fixation (the Kakinuma method).
METHODS The study patients were 30 individuals with POP who underwent surgery using the Kakinuma method between January 2020 and December 2021 and who were followed up for > 12 mo after surgery. We retrospectively examined surgical outcomes for surgery duration, blood loss, intraoperative complications, and incidence of recurrence. The Kakinuma method involves round ligament suturing and fixation on both sides, effectively lifting the vaginal stump after laparoscopic hysterectomy.
RESULTS The patients’ mean age was 66.5 ± 9.1 (45-82) years, gravidity was 3.1 ± 1.4 (2-7), parity was 2.5 ± 0.6 (2-4) times, and body mass index was 24.5 ± 3.3 (20.9-32.8) kg/m2. According to the POP quantification stage classification, there were 8 patients with stage II, 11 with stage III, and 11 with stage IV. The mean surgery duration was 113.4 ± 22.6 (88-148) min, and the mean blood loss was 26.5 ± 39.7 (10-150) mL. There were no perioperative complications. None of the patients exhibited reduced activities of daily living or cognitive impairment after hospital discharge. No cases of POP recurrence were observed 12 mo after the operation.
CONCLUSION The Kakinuma method, similar to conventional NTR, may be an effective treatment for POP.

Abstract
Background Giant malignant tumors have an increased risk of intraoperative rupture, which might lead to a worse disease condition and tumor recurrence. We performed a clinical study on patients with a giant ovarian mass who underwent laparoscopy combined with an Aron Alpha method. Methods This retrospective clinical study spanned from January 2016 to September 2022 and included 23 patients with giant ovarian tumors treated with an Aron Alpha method. Results The mean age of the subjects was 47.6 ± 17.8 years, mean tumor diameter 20.4 ± 5.8 cm, mean surgical duration 87.2 ± 33.1 min, and mean hemorrhage volume 94.1 ± 92.2 mL. No patient experienced intraoperative tumor rupture or surgery-related symptoms. Histopathology of excised samples revealed serous cyst adenoma and mucinous cystadenoma, mucinous cystadenoma of borderline malignancy and mature cystic teratoma, and endometriotic cyst adenoma in 6, 4, and 3 patients, respectively. The mean hospitalization period was 6.0 ± 1.2 days, and the hospitalization period was not extended in any subject. Conclusion The Aron Alpha method allows tumor resection without capsular rupture and is a useful, minimally invasive surgical method for resecting giant ovarian tumors in which malignancy cannot be ruled out.

Abstract
BACKGROUND Hypermenorrhea is characterized by excessive menstrual bleeding that causes severe anemia and interferes with everyday life. This condition can restrict women’s social activities and decrease their quality of life. Microwave endometrial ablation (MEA) using a 2.45-GHz energy source is a minimally invasive alternative to conventional hysterectomy for treating hypermenorrhea that is resistant to conservative treatment, triggered by systemic disease or medications, or caused by uterine myomas and fibrosis. The popularity of MEA has increased worldwide. Although MEA can safely and effectively treat submucous myomas, some patients may still experience recurrent hypermenorrhea postoperatively and may require additional treatment.
AIM To investigate the efficacy of MEA combined with transcervical resection (TCR).
METHODS Participants underwent cervical and endometrial evaluations. Magnetic resonance imaging and hysteroscopy were performed to evaluate the size and location of the myomas. TCR was performed before MEA using a hystero-resectoscope. MEA was performed using transabdominal ultrasound. The variables included operation time, number of ablation cycles, length of hospital stay, and visual analog scale cores for hypermenorrhea, dysmenorrhea, and treatment satisfaction at 3 and 6 mo postoperatively. The postoperative incidence of amenorrhea, changes in hemoglobin concentrations, and MEA-related complications were evaluated.
RESULTS A total of 34 women underwent a combination of MEA and TCR during the study period. Two patients were excluded from the study as their histopathological tests identified uterine malignancies (uterine sarcoma and endometrial cancer). The 32 eligible women (6 nulliparous, 26 multiparous) had a mean age of 45.2 ± 4.3 years (range: 36–52 years). Patients reported very severe hypermenorrhea (10/10 points on the visual analog scale) before the procedure. However, after the procedure, the hypermenorrhea scores decreased to 1.2 ± 1.3 and 0.9 ± 1.3 at 3 and 6 mo, respectively (P < 0.001). The mean follow-up duration was 33.8 ± 16.8 mo. Although 10 women (31.3%) developed amenorrhea during this period, none experienced a recurrence of hypermenorrhea. No surgical complications were observed.
CONCLUSION Reducing the size of uterine myomas by combining MEA and TCR can safely and effectively treat hypermenorrhea in patients with submucous myomas.

Abstract
BACKGROUND Corrected transposition of the great arteries (cTGA) is a cardiac malformation in which the ventricular and arterial-ventricular positions in the heart are doubly reversed. In general, this defect puts a load on the systemic circulation and causes heart failure, resulting in a poor prognosis. This article reports a case of cTGA detected in a patient with post-caesarean pregnancy who had undergone elective caesarean section and was experiencing an episode of acute heart failure.
CASE SUMMARY This was the case of a 36-year-old gravida 3 para 1 woman. No problems were noted in the puerperal course following the previous pregnancy. The current pregnancy was also uneventful. An elective caesarean section was performed and the patient was discharged from the hospital 7 d after the operation. On postoperative day 18, the patient became aware of breathing difficulty and presented at a nearby clinic, where she was referred to our institution after bilateral pleural effusions were detected. She was then diagnosed with acute heart failure after noting the presence of a prominent pedal oedema and SpO2 91% (supine position and room air); the patient was promptly hospitalised for close examination and treatment. Although chest computed tomography revealed the presence of cTGA, no other cardiac malformations were observed. Owing to improvements in both the pedal oedema and pleural effusions, the patient was discharged on day 9.
CONCLUSION Close examination should be performed on the premise of congenital cardiac malformation when heart failure symptoms are noted during perinatal control.

Abstract
Objective To assess the effectiveness and safety of modified silicone gel sheets applied to hypertrophic scars and keloids following laparoscopic surgery. Methods Patients who had undergone laparoscopic surgery and who had either conventional or modified silicone gel sheets affixed to their surgical lesions for 6 months postoperatively (treatment groups), and control patients who had not received postsurgical treatment involving silicone gel sheets, were enrolled. The surgical wounds were assessed visually and using the Japan Scar Workshop (JSW) Scar Scale. Patients were interviewed before, 3 months after, and 6 months after sheet affixation. Results A total of 45 patients were included, comprising 15 patients per group. Both silicone gel-sheet groups had significantly lower JSW Scar Scale scores at 3 and 6 months after affixation compared with controls. The scores were not significantly different between the conventional and modified treatment groups and no adverse events were observed in the latter. Conclusions Modified silicone gel sheets were more effective than controls and comparable to conventional gel sheets, and there were no adverse events related to laparoscopic surgical wounds in the improved silicone gel sheet group, demonstrating the safety and effectiveness of the modified silicone gel sheets.

Abstract
Background In Japan, dilatation & curettage (D&C) has been performed under general anesthesia as a surgery for an early pregnancy miscarriage for a long time. In 2016, manual vacuum aspiration (MVA) under general anesthesia was introduced at our hospital and has been used as a surgical treatment for first-trimester pregnancy miscarriage, with its utility to date being reported here. In July 2018, our hospital introduced the MVA procedure under local anesthesia. In this study, we evaluated the efficacy and safety of MVA under general and local anesthesia in first-trimester pregnancy miscarriage surgery in Japanese women. Methods In this retrospective observational cohort study, we enrolled 322 pregnant women at less than 12 weeks of gestation, who underwent MVA surgery under local anesthesia (n = 166) or conventional general anesthesia (n = 156). The duration of surgery, blood loss volume, quantity of anesthesia, presence or absence of retained products of conception, and clinical complications were evaluated. In addition, the intraoperative pain and treatment satisfaction were assessed using the visual analog scale (VAS). Results The duration of surgery was significantly shorter in the local anesthesia group. No significant differences were observed between both groups in terms of the blood loss volume and incidence of retained products of conception. In addition, no serious complications were observed in either group. No significant differences were noted between the two groups in the VAS scores for pain and treatment satisfaction. Conclusions In this retrospective study, the use of MVA under local anesthesia for early pregnancy miscarriage surgery was found to be equally safe and effective when performed under conventional general anesthesia. This technique allowed the achievement of appropriate pain control with excellent patient satisfaction.

Abstract
Introduction: We report a patient with osteoid osteoma that developed in the lunate. Case Report: The patient was a healthy 28-year-old male who had the right wrist joint pain and osteosclerosis of the lunate was noted on plain radiography. Kienböck’s disease was considered at the first examination, but a nidus was observed on computed tomography, suggesting osteoid osteoma in the lunate. The resection of the bone lesion and bridging external fixation to prevent post-operative collapse of the lunate was performed. Histopathological diagnosis was also osteoid osteoma in the lunate. At 3 years after surgery, no recurrence of the lesion or progression of collapse of the lunate has occurred. Conclusion: As the development of osteoid osteoma in the lunate is a markedly rare pathology and there are many differential diseases, the time to diagnosis may be prolonged. Moreover, it may be useful to attach bridging external fixation to prevent a collapse of the lunate.

Abstract
Introduction: Although vascularized bone grafting (VBG) using 1, 2 intercompartmental supraretinacular artery (1, 2 ICSRA) is effective for scaphoid nonunion, dorsal intercalated segment instability (DISI) deformity persists even after correction of humpback deformity (HD). The purpose of this retrospective study was to evaluate the correction of HD and DISI deformity after 1, 2 ICSRA VBG for scaphoid nonunion. Methods: We treated 18 patients (mean age: 25.8, 16 males and 2 females) with scaphoid nonunion using a 1, 2-ICSRA VBG between January 2010 and December 2018. The average time from injury to surgery was 20.0 (3–120) months. The nonunions were located at the waist in all patients. The correction of HD and DISI deformity was investigated on the preoperative images and images at the last examination. Results: In all patients, the correction of HD was positively correlated with that of DISI deformity. Moreover, we focused on the time from injury to surgery and evaluated changes in HD and DISI deformity according to the time to surgery. As a result, changes in HD and DISI deformity were positively correlated in patients with a shorter time to surgery but were not correlated when the time to surgery exceeded 5 months. Conclusions: These results suggest that DISI deformity can be corrected by correcting HD when the time from injury to surgery is short, but that correction is difficult if the time to surgery is prolonged.

Abstract
When severe proximal interphalangeal (PIP) joint flexion contracture is induced in the little finger by Dupuytren’s disease, it interferes with activities of daily living. To extend the little finger, open fasciectomy is selected as a general treatment method. However, postoperative complications have been frequently reported. To solve these problems, finger shortening was undertaken. In this study, we treated two cases of Dupuytren’s disease manifesting severe PIP joint flexion contracture of the little finger with finger shortening by proximodistal interphalangeal (PDIP) fusion in which the middle phalanx is resected and the residual distal and proximal phalanges are fused. For flexion contracture of the MP joint, a percutaneous aponeurotomy using an 18G needle was performed to obtain the extended position of the MP joint. Favorable outcomes with high patient satisfaction, including esthetic aspects of retaining the finger with the nail without complication, were achieved. We report this challenging treatment and its discussion.

Abstract
Background: The treatment strategy for distal radius fractures accompanied by volar lunate facet fragment is controversial. In most cases, only the bone fragment size was discussed and a plate for distal placement is selected due to the accompanying volar lunate facet fragment regardless of the direction of bone fragment displacement. In this study, we divided distal radius fractures accompanied by volar lunate facet fragment into dorsal and volar displaced fractures, and treated these surgically based on different treatment strategies. Methods: The subjects were 25 patients with distal radius fractures accompanied by volar lunate facet fragment treated by reduction and fixation using a volar locking plate (VLP) (male: 14, female: 11, mean age: 57.8 years old). A proximal VLP (PVLP) was selected for 13 dorsal displaced fractures and a distal VLP (DVLP) was selected for 12 volar displaced fractures. The range of motion, VAS, Q-DASH, and Mayo score were evaluated at 12 months after surgery, and compared. Results: No significant difference due to the difference in the direction of displacement was noted in the range of motion, VAS, Q-DASH, or Mayo score at 12 months after surgery and there were no perioperative complications. In addition, no re-displacement of volar lunate facet fragment was noted after surgery in any patient and bone fusion was observed. Conclusions: Reduction and fixation with a PVLP are possible even for dorsal displaced distal radius fractures accompanied by volar lunate facet fragment. For the volar displaced distal radius fractures, a favorable postoperative outcome is possible by applying a DVLP to the distal ulnar.

Abstract
Chimpanzees are genetically and physiologically similar to humans. Several pharmacokinetic models of propofol are available and target controlled infusion (TCI) of propofol is established in humans, but not in chimpanzees. The purpose of this study was to investigate if human pharmacokinetic models can accurately predict propofol plasma concentration (Cp) in chimpanzees and if it is feasible to perform TCI in chimpanzees. Ten chimpanzees were anaesthetized for regular veterinary examinations. Propofol was used as an induction or maintenance agent. Blood samples were collected from a catheter in a cephalic vein at 3–7 time points between 1 and 100 min following the propofol bolus and/or infusion in five chimpanzees, or TCI in six chimpanzees. Cp was measured using high-performance liquid chromatography. The Marsh, Schnider and Eleveld human pharmacokinetic models were used to predict Cp for each case and we examined the predictive performances of these models using the Varvel criteria Median PE and Median APE. Median PE and Median APE for Marsh, Schnider and Eleveld models were within or close to the acceptable range. A human TCI pump was successfully maintained propofol Cp during general anesthesia in six chimpanzees. Human propofol pharmacokinetic models and TCI pumps can be applied in chimpanzees.

Abstract
Introduction: Although many clinical studies about distal radius fracture (DRF) accompanied by volar lunate facet fragments (VLFF) have recently been reported, none focus on the direction of displacement of distal fragments. Many previous cases with difficulty in treating DRF with VLFF were volar-displaced fractures. Thus, the postoperative risk for re-displacement is different between volar- and dorsal-displaced fractures with VLFF. The aim of this study is to compare the outcome of dorsal-displaced fractures treated using proximal volar locking plates (PVLP) between those with VLFF and those without, in order to reconsider the indications of distal volar locking plates (DVLP) and investigate the possibility of treating dorsal-displaced DRF with VLFF using PVLP. Methods: The subjects were 122 patients with dorsal-displaced DRFs treated using PVLP (42 males and 80 females, mean age: 59.2 years old). The patients were divided into 13 patients with VLFF group and 109 patients without VLFF group, and the clinical outcomes at 12 months after surgery were compared. Results: No significant difference was noted on any evaluation between the groups. In addition, no postoperative re-displacement of VLFF was observed and bone union was confirmed. Furthermore, no osteoarthritic change was noted in all patients. Conclusions: We confirmed that surgical treatment for dorsal-displaced DRF using PVLP is possible even in cases of DRF with VLFF. In addition, DVLP is an implant with a high complication risk; therefore, it may be necessary to reconsider the use of DVLP for dorsal-displaced DRF with VLFF treatable by PVLP.

Abstract
The influence of aging on the induction of nerve regeneration in artificial nerve conduits has yet to be clarified. In the present study, artificial nerve conduit transplantation and histological analysis using the sciatic nerve of young and elderly mice were performed. Using 20 male C57BL/6 mice, an artificial nerve conduit was transplanted to the sciatic nerve at 8 weeks (Young group) or 70 weeks of age (Aged group), and the sciatic nerve was evaluated histologically at 1, 4 and 12 weeks after surgery. Using hematoxylin and eosin staining, the state of induction of nerve regeneration in the artificial nerve conduit was evaluated. Additionally, immunohistochemical staining was used to investigate an angiogenic marker [vascular endothelial growth factor A (VEGFA)], Schwann cell markers [sex determining region Y-box 10 (SOX10) and S100 calcium-binding protein β (S100β)] and a nerve damage marker [nerve growth factor (NGF)]. The results revealed that the induction of nerve regeneration was significantly higher in the Young group than in the Aged group. In addition, VEGFA and SOX10 expression at 1 week, SOX10 expression at 4 weeks and SOX10, S100β and NGF expression at 12 weeks in the proximal stump were significantly higher in the Young group than in the Aged group. At the center of the artificial nerve conduit, S100β and NGF expression at 4 weeks, and VEGFA, SOX10, S100β and NGF expression at 12 weeks were significantly higher in the Young group than in the Aged group. In the distal stump, no significant difference was noted in immunostaining at any week between the two groups. The present study suggested that the nerve regeneration-inducing functions decrease due to aging.

Abstract
Exploration of artworks is enjoyable but often time consuming. For example, it is not always easy to discover the favorite types of unknown painting works. It is not also always easy to explore unpopular painting works which looks similar to painting works created by famous artists. This paper presents a painting image browser which assists the explorative discovery of user-interested painting works. The presented browser applies a new multidimensional data visualization technique that highlights particular ranges of particular numeric values based on association rules to suggest cues to find favorite painting images. This study assumes a large number of painting images are provided where categorical information (e.g., names of artists, created year) is assigned to the images. The presented system firstly calculates the feature values of the images as a preprocessing step. Then the browser visualizes the multidimensional feature values as a heatmap and highlights association rules discovered from the relationships between the feature values and categorical information. This mechanism enables users to explore favorite painting images or painting images that look similar to famous painting works. Our case study and user evaluation demonstrates the effectiveness of the presented image browser.

Abstract
Objectives Distal radius fractures occur due to reflex clasp when falling. Recently, attention has been focused on the strong relationship between sagittal spine alignment and falls. Therefore, we investigated the parameters of sagittal spinal alignment in distal radius fractures in female patients. Patients and methods The subjects were group D: 28 female patients with distal radius fractures aged 50 years or older (mean age: 69.3 years), and group C: 26 healthy female patients without a history of fragility fractures (mean age: 70.5 years). Height, body weight, and body mass index (BMI) were measured as physical indices. As parameters of sagittal spinal alignment, the sagittal vertical axis (SVA), pelvic tilt (PT), pelvic incidence (PI), sacral slope (SS), lumber lordosis (LL), and thoracic kyphosis (TK) were measured on lateral whole-spine plain radiographs in a standing position. The measured physical indices and sagittal spinal alignment parameters were compared between groups. Results Height, weight, and BMI did not differ significantly between the two groups. Among the sagittal spinal alignment parameters, PT, PI, SS, LL, and TK did not differ significantly between groups, whereas SVA was significantly higher in group D than in group C (P < 0.05). Conclusion In this study, SVA was significantly higher in group D than in group C. As SVA increased, the center of gravity of the body shifts forward, which can cause the body to lose balance and fall. This study suggested that an increase in SVA is associated with distal radius fractures.

Abstract
Abstract
Introduction There are various studies that reviewed the effect of cigarette smoking in fracture healing process. Nonunion, delayed union, and residual pain are the significant risk factors associated with smoking and fracture healing. Little has been known about the impact of smoking in distal radius fracture healing. We intend to explore in brief the effect of smoking in distal radius fracture healing and comparing it with nonsmokers having the same fracture fixation and analyze the outcomes with respect to fracture healing and return of function.
Materials and Methods Of the total 186 patients, 92 were included in the study with (n = male: 31, female: 61) mean age of 60.2 years. They were divided into two groups: smoking (n = 43) and nonsmoking (n = 49). All had surgical fixation of the distal radius with volar locking plate and started on early mobilization. The range of motion of the wrist, grip, visual analog scale, quick disabilities of the arm and shoulder and hand score, Mayo wrist score, and bone healing period were noted between these two groups and compared with statistical analysis.
Results The mean follow-up period was 8.7 months. There was a significant association of young age and male patients having distal radius fractures in the smoking group (p < 0.05). All fractures healed well in both groups without complications. There was no significant difference between these two groups in terms of range of motion, grasp, bone healing period, and functional outcomes.
Conclusion Despite the well-known fact that, smoking has negative implications in the fracture healing process, we found group of patients (smoking and nonsmoking) with distal radius fractures treated by volar locking plates healed well with good radiological union and excellent functional outcome There is no significant influence of smoking in distal radius fracture fixation.

Abstract
Background: Postoperative evaluation of wrist joint trauma is divided into patient-reported outcomes (PROs) and clinician-reported outcomes (CROs). We investigated the association of the Q-DASH score as the postoperative PROs and the Mayo wrist score as the postoperative CROs with clinical evaluation in patients with distal radius fractures surgically treated using a volar locking plate (VLP). Moreover, whether PROs and CROs are correlated to the clinical evaluation was investigated. Methods: The subjects were 109 patients surgically treated for distal radius fractures at our hospital between June 2013 and May 2017. Forty-one patients were male, 68 patients were female, and the mean age was 61.4 (19-86) years old. The fracture type was AO classification A type in 30 patients (A2: 25, A3: 5), B type in 5 (B2: 1, B3: 4), and C type in 74 (C1: 50, C2: 11, C3: 13). All patients were surgically treated using VLP. The range of motion of the wrist, grip strength the Visual Analog Scale (VAS), the Q-DASH score (PROs), and the Mayo wrist score (CROs) were investigated. Each evaluation was compared as the clinical outcome between at 3 months after surgery and the final follow-up. In addition, the correlations of the postoperative PROs and CROs with the clinical evaluation were analyzed. Results: Each evaluation was significantly improved compared with that at 3 months after surgery. There was a significant correlation between PROs and CROs at 3 months after surgery and the final follow-up. However, the range of motion of the wrists was not significantly correlated with PROs or CROs at 3 months after surgery or at the final follow-up. Conclusions: On evaluation after surgery for distal radius fractures, PROs and CROs improved early after surgery (3 months after surgery) before the final follow-up, and an inverse correlation was present between these scores.

Abstract
Background:In Japan, oral tacrolimus (TAC) was approved for the treatment of RA in 2005 and the improvement of symptoms thorough the use concomitant with disease modifying antirheumatic drugs (DMARDs), including MTX has been reported1 2. On the other hand, the efficacy and tolerance of biological agents therapy concomitant with TAC are unknown.Objectives:The objective of this study was to investigate the efficacy and tolerance of biological agents concomitant with TAC in Japanese patients with RA using retention rate analysis.Methods:Total patients (n=2860) who underwent 5 biological agents (etanercept: ETN, adalimumab: ADA, golimumab:GLM, tocilizumab: TCZ, abatacept: ABT) treatment between 2003 and 2017 at Nagoya University Hospital and 12 other institutes (Tsurumai Biologics Communication Study Group) were enrolled3. In each biologics analysis, patients were divided into three groups: (1) concomitant only MTX (MTX group) (2) concomitant only TAC (TAC group) (3) others (others group). In TAC or MTX group, these drugs were only ones which concomitant with biologics. Kaplan-Meier analysis was used to estimate retention rate in each biologics group. To estimate the tolerance of concomitant biologics with TAC, cumulative hazard function in adverse events rate was performed in each biologics group. In both analyses, hazard ratios (HR) were assessed by Cox proportional hazards modeling adjusted for age, sex, disease duration and previously used biologics.Results:In total 2860 patients, 142 patients (5.0%) administered each biologics concomitant with TAC (ETN: n=47, ADA: n=10 GLM: n=14, TCZ: n=27, ABT: n=49). Baseline characteristics of 142 patients were shown in table 1. Average dosages of TAC at starting were ETN: 2.2±0.7mg ADA: 2.4±1.0mg GLM: 1.9±1.0mg TCZ: 1.7±0.9mg ABT: 1.9±0.9mg. With comparison of retention rate between 3 groups in each biologics under analysis of cox proportional hazard modeling, in ETN and ABT analysis, the retention rate of TAC group was higher than others group (table 2, figure 1). Comparison of incidence of adverse event between 3 group using cumulative hazard function and cox proportional hazard modeling in ETN and ABT analysis. In ETN analysis, incident rate of other group was higher than TAC group. In ABT analysis, there was no significant difference between 3 gruops (figure 2).Table 1.Baseline characteristic (n=142)age (years)63 ± 3gendermale33 (23%)female109 (77%)disease duration (years)12.0 ± 7.8stage1,234 (24%)3,4108 (76%)class1,299 (70%)3,443 (30%)naïve vs switchnaïve71 (50%)switch71 (50%)corticosteroid use, no (%)+98 (75%)-32 (25%)corticosteroid dose (mg)5.6 ± 3.2DAS28-ESR4.71 ± 1.55Table 2.HR (95%CI)/p-valuen (MTX/TAC/others)ETNADAGLMTCZABT(774/ 47/ 486)(339/ 10/ 135)(156/ 14/ 61)(272/ 27/ 207)(213/ 49/ 178)TAC vs others0.27 (0.16-0.45)<0.0010.9 (0.37-2.20)ns0.46 (0.13-1.63)ns0.55 (0.24-1.31)ns0.51 (0.26-0.97)<0.05TAC vs MTX0.65 (0.38-1.08)ns1.42 (0.61-3.31)ns0.83 (0.24-2.87)ns0.5 (0.21-1.17)ns0.74 (0.39-1.42)nsMTX vs others0.42 (0.35-0.50)<0.0010.9 (0.50-0.88)<0.0010.56 (0.33-0.96)<0.051.01 (0.78-1.57)ns0.68 (0.46-0.99)<0.05Bold italic: p<0.05CI: confidence interval ns: not significantConclusion:We suspected that, in ETN and ABT treatment, combination therapy with TAC are subsequent options for treatment to RA patients, especially in whom MTX cannot be administration.References:[1]Kino T, et al.

Abstract
BACKGROUND Prevention of redisplacement is an issue after the treatment of fractures of the distal third of the radius in children. In this study, we used a locked wires fixator for this type of fracture and achieved favorable treatment outcomes. METHODS The subjects were 8 children with fractures of the distal third of the radius (male: 7, female: 1, mean age: 9.0 years old) who underwent surgery with locked wires fixators and were able to be evaluated 12 months after surgery. Immobilization was not applied after surgery. The locked wires fixator or K-wire was removed when the bridging callus was observed on plain radiography 4-6 (mean 5.5) weeks after surgery in all patients. The presence of bone union, functional outcomes, and complications were investigated postoperatively. RESULTS All patients achieved bone union without redisplacement excellent function. The pin site infection was observed in two patients. CONCLUSIONS The locked wires fixator may be a new useful treatment method for fractures likely to cause postoperative redisplacement.

Abstract
AIMS Senescence is the normal decline in physiological functions due to aging that results in cell dysfunction. However, age-associated changes in peripheral nerves have not been elucidated. We observed histological changes in the sciatic nerves of young and older mice to investigate how peripheral nerves changed with age, and we evaluated protective mechanisms of peripheral nerves against aging. MAIN METHODS Sciatic nerves were collected from female C57BL/6 mice at the ages of 8 weeks (young group) and 78 weeks (aged group) and examined histologically. Using hematoxylin and eosin staining, the number and density of sciatic nerve axons were evaluated. Through immunofluorescence staining, the expression of nerve-specific proteins, oxidative stress markers, and a neuronal aging marker (REST/NRSF) were investigated, and the intensity of fluorescence was quantified. The differences between the groups were assessed, and age-associated peripheral nerve changes were evaluated. Statistical analysis was performed using the Mann-Whitney U test. KEY FINDINGS Although the number and density of axons did not differ significantly between the groups, they were lower in the aged group than in the young group. In addition, the fluorescence intensity of each marker did not differ significantly between the groups, but the expression of REST/NRSF alone was significantly higher in the aged group than in the young group (p < 0.05). SIGNIFICANCE This study suggested that peripheral nerve functions are preserved by the expression of REST/NRSF, which increases with age. Because oxidative stress did not change, the protective effects of REST/NRSF are considered to be related to oxidative stress.

Abstract
BACKGROUND The aim of this study was to assess the height of nonunion formation injuring the ulnar-side finger flexor tendon, the positional relationship between the hook of the hamate and little finger flexor tendon was evaluated on CT scans. METHODS The subjects were 20 healthy patients (40 hands) (14 males and 6 females, mean age: 28 years old). Their hands were imaged in extension and flexion of the fingers on CT. The position of the little finger flexor tendon was determined regarding the height of the hook of the hamate as 100%. RESULTS The heights of the flexor digitorum profundus tendons were 46 ± 6% in extension and 44 ± 9% in flexion, and those of the flexor digitorum superficialis tendons were 87 ± 8% in extension and 91 ± 9% in flexion. CONCLUSIONS Our study suggested that 40% of the base of the hook of the hamate does not contact with the flexor tendon, suggesting that flexor tendon injury is unlikely to occur in that region.

Abstract
RATIONALE Cubital tunnel syndrome has been recognized as a common pathology in rheumatoid arthritis (RA) of the elbow. We encountered a patient with RA of the elbow showing attrition rupture of the ulnar nerve. This pathology is extremely rare, and we discussed preventive measures for similar cases in the future based on our case. PATIENT CONCERNS A 53-year-old woman, received drug treatment for RA since 30 years earlier, had numbness in the left ulnar nerve territory, dorsal interossei muscle atrophy, and resulting claw hand. DIAGNOSES Plain x-ray examination showed bone destruction of the left elbow joint and marked osteophyte formation in the medial joint space. In nerve conduction velocity (NCV) tests, the Motor NCV was immeasurable in the ulnar nerve territory. Based on these findings, a diagnosis of left cubital tunnel syndrome was made, and anterior transposition of the ulnar nerve was planned. INTERVENTIONS When the ulnar nerve dissection was advanced, about 80% portion of the ulnar nerve was ruptured. After the ends of the divided nerve were freshened, end-to-end anastomosis was possible by anterior transposition of the ulnar nerve. OUTCOMES Two years after the operation, numbness and muscle atrophy also remained. There were no changes in the level of daily activities after the operation. However, motor NCV, showed improvement (22.8 m/s) after the operation. LESSONS In patients with RA showing ulnar neuropathy symptoms, marked osteophyte formation in the medial joint space or valgus deformity may indicate attrition nerve rupture. In the future, when such patients with RA are examined, active nerve exposure and dissection should be considered in terms of ulnar nerve protection.

Abstract
BACKGROUND In recent years, installation of bidet toilets within hospitals in Japan has raised concerns regarding potential for cross-contamination by antimicrobial-resistant bacteria from patients who are hospitalized over an extended period. AIM To investigate the distribution of antimicrobial-resistant bacteria recovered from bidet toilets at a university-affiliated hospital in Japan. METHODS All 292 electric bidet toilets at a university hospital were sampled for contamination. Swabs for culture were used to sample water-jet nozzles and toilet seats. FINDINGS Of the 292 toilet seats sampled, warm-water nozzles of 254 (86.9%) were found to be contaminated by one or more of the following organisms: Staphylococcus aureus, Streptococcus spp., Enterococcus spp., Enterobacteriaceae and non-Enterobacteriaceae Gram-negative bacteria. S. aureus was recovered from one water-jet nozzle and nine toilet seats; of these, meticillin-resistant S. aureus was recovered from the water-jet nozzle and from one toilet seat. Both the water-jet nozzle and seat of the same toilet were contaminated with a CTX-M-9 group extended-spectrum β-lactamase-producing Escherichia coli. Of the Gram-negative isolates recovered from samples, the organism with the highest frequency of isolation was Stenotrophomonas maltophilia, which was recovered from 39 bidet toilets. CONCLUSION Warm-water nozzles of bidet toilets are contaminated with a wide range of bacteria, making them a potential vehicle for cross-infection. In the hospital setting, shared use of bidet toilets must consider the clinical background of patients. Based on these findings, these devices must be part of the risk management programme, and steps should be included for monitoring and disinfection.

Abstract
BACKGROUND Stimulation of transient receptor potential ankyrin 1 (TRPA1), which abundantly expressed in enterochromaffin cells (ECC), has been reported to exert apparently contradictory results in in vitro contractility and in vivo gastrointestinal (GI) transit evaluations. The pharmaceutical-grade Japanese traditional medicine daikenchuto (TU-100) has been reported to be beneficial for postoperative ileus (POI) and accelerate GI transit in animals and humans. TU-100 was recently shown to increase intestinal blood flow via stimulation of TRPA1 in the epithelial cells of the small intestine (SI). METHODS The effects of various TRPA1 agonists on motility were examined in a manipulation-induced murine POI model, in vitro culture of SI segments and an ECC model cell line, RIN-14B. KEY RESULTS Orally administered TRPA1 agonists, aryl isothiocyanate (AITC) and cinnamaldehyde (CA), TU-100 ingredients, [6]-shogaol (6S) and γ-sanshool (GS), improved SI transit in a POI model. The effects of AITC, 6S and GS but not CA were abrogated in TRPA1-deficient mice. SI segments show periodic peristaltic motor activity whose periodicity disappeared in TRPA1-deficient mice. TU-100 augmented the motility. AITC, CA and 6S increased 5-HT release from isolated SI segments and the effects of all these compounds except for CA were lost in TRPA1-deficient mice. 6S and GS induced a release of 5-HT from RIN-14B cells in a dose- and TRPA1-dependent manner. CONCLUSIONS & INFERENCES Intraluminal TRPA1 stimulation is a potential therapeutic strategy for GI motility disorders. Further investigation is required to determine whether 5-HT and/or ECC are involved in the effect of TRPA1 on motility.
