We report on a rare case of a left subclavian artery aneurysm concomitant with Loeys-Dietz Syndrome (LDS) which required us to operate in childhood. A 12-year-old female, who had been diagnosed with LDS by genetic examination one year eariler, was revealed to be suffering from a left subclavian artery aneurysm (25 mm in diameter) by follow up chest MRI scan. Hybrid surgery consisting of coil embolization of aneurysm and surgical revascularization of the left subclavian artery and left vertebral artery was performed successfully. The patient was discharged on postoperative day 8.

Insufficient physical function is strongly associated with decreased activity of daily living and health-related quality of life in middle-aged and older women. YOSAKOI Soran is one of the traditional Japanese dances to have naruko (wooden hand clappers) in their hands as they dance and incorporate the phrase from the Soran Bushi in their song. YOSAKOI Soran festivals can be seen being held in various places across the country, proving its growing popularity with residents as a celebration regardless of age or occupation. The purpose of this study was to examine the cross-sectional associations between YOSAKOI Soran and the physical functions of middle-aged and older women. A total of 30 middle-aged and older women practicing YOSAKOI Soran (YOSAKOI group) and 163 middle-aged and older women who had not practiced YOSAKOI Soran (control group) participated in this cross-sectional study. Handgrip strength, 30-second chair stand performance, and flexibility were used to measure physical functions. Handgrip strength was not significantly differed between the YOSAKOI group and the control group (P = 0.79). 30-second chair stand performance and flexibility were significantly higher in the YOSAKOI group than in the control group (both P < 0.05). These results remained significant after adjusting for age and body mass index (both P < 0.05). The present results suggest that practicing YOSAKOI Soran may increase lower extremity function and flexibility in middle-aged and older women.

Prevention, early diagnosis, and early treatment of skeletal-related events (SREs) are important in the treatment of potential or current cases of bone metastasis. In August 2020, our hospital established the bone metastasis team and the bone metastasis board (BMB) started actively engaging in activities aimed at improving the outcome of bone metastasis. We retrospectively examined whether a combined modality therapy started in the diagnosis of bone metastases could prevent the onset of SREs and whether it could prolong survival and improve activities of daily living. The 75 advanced cancer patients who underwent BMB at our hospital from August 1, 2020 to July 31, 2022 were divided into two groups according to when BMB performed before and after SREs for comparative analysis. Numerical Rating Scale improved, however Performance Status did not improve in both groups, and there was no difference in survival between the both groups (15.3 vs. 9.0 months, HR: 0.74, 95%; CI: 0.42–1.29, p=0.29). In conclusion, patients who suffered from SREs from the time of bone metastasis diagnosis were treated early. However, the incidence of SREs after BMB in our hospital was 22.6%, and it is necessary to actively work to prevent SREs in the future.

BACKGROUND/AIMS: Endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) has been used to diagnose gastrointestinal submucosal tumors (SMTs). Although rapid on-site evaluation (ROSE) has been reported to improve the diagnostic accuracy of EUS-FNA for pancreatic lesions, on-site cytopathologists are not routinely available. Given this background, the usefulness of ROSE by endosonographers themselves for pancreatic tumors has also been reported. However, ROSE by endosonographers for diagnosis of SMT has not been reported. The aim of this study was to evaluate the diagnostic accuracy of EUS-FNA with ROSE by endosonographers for SMT, focusing on diagnosis of gastrointestinal stromal tumor (GIST), compared with that of EUS-FNA alone. METHODS: Twenty-two consecutive patients who underwent EUS-FNA with ROSE by endosonographers for SMT followed by surgical resection were identified. Ten historical control subjects who underwent EUS-FNA without ROSE were used for comparison. RESULTS: The overall diagnostic accuracy for SMT was significantly higher in cases with than without ROSE (100% vs. 80%, p=0.03). The number of needle passes by FNA with ROSE by endosonographers tended to be fewer, although accuracy was increased (3.3±1.3 vs. 5.9±3.8, p=0.06). CONCLUSIONS: ROSE by endosonographers during EUS-FNA for SMT is useful for definitive diagnosis, particularly for GIST.

BACKGROUND/AIMS: Transpapillary forceps biopsy is an effective diagnostic technique in patients with biliary stricture. This prospective study aimed to determine the usefulness of the wire-grasping method as a new technique for forceps biopsy. METHODS: Consecutive patients with biliary stricture or irregularities of the bile duct wall were randomly allocated to either the direct or wire-grasping method group. In the wire-grasping method, forceps in the duodenum grasps a guide-wire placed into the bile duct beforehand, and then, the forceps are pushed through the papilla without endoscopic sphincterotomy. In the direct method, forceps are directly pushed into the bile duct alongside a guide-wire. The primary endpoint was the success rate of obtaining specimens suitable for adequate pathological examination. RESULTS: In total, 32 patients were enrolled, and 28 (14 in each group) were eligible for analysis. The success rate was significantly higher using the wire-grasping method than the direct method (100% vs 50%, p=0.016). Sensitivity and accuracy for the diagnosis of cancer were comparable in patients with the successful procurement of biopsy specimens between the two methods (91% vs 83% and 93% vs 86%, respectively). CONCLUSIONS: The wire-grasping method is useful for diagnosing patients with biliary stricture or irregularities of the bile duct wall.

A multicenter review of the medical records of Japanese post-stroke patients with spastic hemiplegia was conducted to investigate the clinical use of botulinum toxin type A (BoNT/A) by physicians with expertise in the treatment of upper and lower limb spasticity. An analysis of the data from 307 patients treated with BoNT/A during the period January 1, 2012 to November 30, 2013 provided a variety of information on factors relating to BoNT/A injection outcomes, including the total dose of BoNT/A per treatment session, the dose of BoNT/A per muscle, the number of injection sites per muscle, the method used to locate the muscles to be injected, and the dilution of reconstituted BoNT/A. Our analysis indicated that the dose of BoNT/A administered per muscle was usually selected by taking into consideration the severity of spasticity, rather than the patient's body size. Since the technical expertise of experienced clinicians is summarized in this data, it may serve as a useful reference for the use of BoNT/A in routine clinical practice.

Introduction: Prevention of the onset of cardio/cerebrovascular diseases, which represent circulatory system diseases, is now emphasized. It requires ensuring good arterial distensibility, which has been demonstrated to be reduced by life environments such as the lack of exercise or overnutrition but improved by aerobic exercise. Even if implementation of such exercises is possible, it increases the risks of the frail elderly with declined cardiopulmonary function and those with other diseases. This study aimed to focus on plantar flexion and dorsiflexion exercises of the ankles as a type of effective, low-load exercise that can induce dynamic stimulation associated with increased blood flow, using muscle pumping of the triceps surae and footbath, which could potentially increase overall blood flow via hyperthermic action. We then investigate the benefits of the combined effects of these two exercises on arterial distensibility. Methods: We selected 25 physically and mentally healthy adult men and women (17 men and eight women; mean ± SD age, 25.7 ± 3.3 years) as study subjects. All the 25 subjects performed each of three exercises, namely footbath, ankle exercise, and ankle exercise in footbath, in a sitting position for 15 minutes. Ankle-brachial index (ABI), brachial-ankle pulse wave velocity (PWV), systolic blood pressure, diastolic blood pressure, and heart rate were measured using form PWV/ABI before and after the exercise for the evaluation of arterial distensibility. Results: No significant differences were observed in the PWVs, ABIs, systolic/diastolic blood pressures, and heart rates before and after exercise in the footbath and exercise groups. However, for the footbath exercise group, a significant reduction in PWV was observed from before to after exercise. Discussion: In this study, we focused our attention on the ankle exercise in footbath as a low-load exercise that could improve arterial distensibility. The results indicated a significant reduction in PWV, an index used to show the level of arterial distensibility, only for the footbath exercise group, which performed the combination of ankle exercise and footbath. We can infer that the improvement of arterial distensibility is attributed to the synergistic effect of the muscle pump and hyperthermic actions, which result in further increases and facilitation of cardiac output. Conclusions: This study demonstrated that the ankle exercise in footbath was beneficial for the improvement of arterial distensibility.

Objective : To evaluate the efficacy and safety of botulinum toxin type A (BTXA) in Japanese patients with post-stroke lower limb spasticity in a multicenter, randomized, double-blind, single dose, placebo-controlled study (double-blind phase) followed by an open-label, multiple dose extension (open-label phase). Methods : One hundred and twenty patients with lower limb spasticity were randomized to receive a single treatment with BTXA 300 Units (U) or placebo into lower limb muscles in the double-blind phase. Patients who met the re-injection criteria received up to 3 repeated treatments of BTXA into lower limb muscles with at least 12 weeks between treatments in the open-label phase through 48 weeks. Results : In the double-blind phase there was significant improvement from baseline spasticity in the Modified Ashworth Scale (MAS) ankle score between the BTXA 300U and placebo groups, with a mean difference in the area under the curve (AUC) of -3.428 (p=0.006, t test). The MAS ankle score further decreased from baseline in all repeat treatment cycles of BTXA in the open-label phase. No clinically relevant difference was noted in the frequency of treatment-related adverse events between BTXA-treated and placebo-treated patients during the study period. Conclusions : BTXA reduced spasticity in lower limb muscles from the first treatment with continued long-term efficacy. BTXA is safe and effective for the long-term treatment of post-stroke lower limb spasticity.

Objective : To evaluate the efficacy and safety of botulinum toxin type A (BTXA) in Japanese patients with post-stroke upper limb spasticity in a multicenter, randomized, double-blind, single dose, placebo-controlled study (double-blind phase) followed by an open-label, multiple dose extension (open-label phase). Methods : One hundred and nine patients with upper limb spasticity were randomized to receive a single treatment with either a lower dose (120-150 Units ; U), higher dose (200-240U) BTXA or placebo into upper limb muscles in the double-blind phase. These treatments were administered to improve wrist and finger flexion for all patients and thumb flexion in patients with thumb spasticity. Patients who met the re-injection criteria received up to 3 repeated treatments of BTXA (200-240U) into their upper limb muscles with at least 12 weeks between treatments in the open-label phase through 48 weeks. Results : In the double-blind phase there was significant improvement from baseline spasticity on the Modified Ashworth Scale (MAS) wrist score between the higher dose BTXA and placebo groups, with a mean difference in the area under the curve (AUC) of -6.830 (p<0.001, t test). The MAS wrist score further decreased from baseline in all repeat treatment cycles of BTXA in the open-label phase. No clinically relevant difference was noted in the frequency of treatment-related adverse events between BTXA-treated and placebo-treated patients during the study period. Conclusions : BTXA injections reduced spasticity in the upper limb muscles from the first treatment with continued long-term efficacy. Our results suggest that BTXA injections are safe and effective for the long-term treatment of post-stroke upper limb spasticity.
