Background: Regional anesthesia techniques that provide analgesia to the entire lateral abdomen are limited. We present a modified external oblique intercostal block for complete lateral abdominal analgesia with a single injection. Case: We performed a modified version of the external oblique intercostal block unilaterally at the tenth rib along the mid-axillary line in three patients undergoing robot-assisted partial nephrectomy (two single injections, one catheter placement) and tested the technique on a cadaver with 20 ml of dye bilaterally. All patients reported good postoperative pain relief without complications and had consistent sensory coverage of the T8–T12 dermatomes from the anterior-to-posterior axillary line. Anatomical assessment confirmed consistent bilateral staining of the lateral cutaneous branches T8–T12. Conclusions The initial clinical success and anatomical findings of the modified approach to the external oblique intercostal block suggest that this technique may be an effective option for lateral abdominal analgesia.

Background: No consensus exists regarding which anthropometric measurements are related to bone mineral density (BMD), and this relationship may vary according to sex and age. A large Japanese cohort was analyzed to provide an understanding of the relationship between BMD and anthropometry while adjusting for known confounding factors. Methods: Our cohort included 10,827 participants who underwent multiple medical checkups including distal forearm BMD scans. Participants were stratified into four groups according to age (≥50 years or <50 years) and sex. The BMD values were adjusted for confounding factors, after which single and partial correlation analyses were performed. The prevalence of osteopenia was plotted for each weight index (weight or body mass index [BMI]) class. Results: Cross-sectional studies revealed that weight was more favorably correlated than BMI in the older group (R=0.278 and 0.212 in men and R=0.304 and 0.220 in women, respectively), whereas weight and BMI were weakly correlated in the younger age groups. The prevalence of osteopenia exhibited a negative linear relationship with weight among older women ≥50 years of age, and an accelerated increase was observed with decreasing weight in older men weighing <50 kg and younger women weighing <60 kg. When weight was replaced with BMI, the prevalence was low in most subgroups classified by weight. Conclusions Weight, rather than BMI, was the most important indicator of osteopenia but it might not be predictive of future bone loss.

[Objective]To investigate the effects of acupuncture on sports activities of athletes[Methods]A total of 1,804 athletes were targeted. The method used was a collective survey. Questionnaires were administered after obtaining consent from the participants; online questionnaires were also provided. The questionnaire evaluated profile (sex, age); sensation immediately after acupuncture treatment, duration of stimulus sensation, stimulus intensity, stimulus sensation, and therapeutic effect; timing of acupuncture treatment; and questions related to acupuncture as to whether the acupuncture caused any adverse effects on play (movement) or showed any positive effects.[Results]In total, 1,525 (84.5%) valid responses were obtained. The survey analyzed 841 subjects (55.1%) who underwent acupuncture. The most common response after acupuncture treatment was that the subjects felt lighter and were able to move more easily; 43.9% of subjects gave this response. In addition, 10.6% of respondents said that they continued to feel pain similar to the sensation during acupuncture treatment and 7.7% said they felt weak. The most common response at 59.8% was that the sensation felt during acupuncture disappeared quickly after treatment was ended, 58.6% of subjects said that the sensation felt after acupuncture was optimal, and 48.3% responded that the sensation from treatment remained and a positive effect was observed. The most common timing for receiving acupuncture for 21.8% of subjects was after practice or a match: [Discussion and Conclusion]Acupuncture for athletes should be performed according to the guidelines, taking into account the competition schedule and type of competition and the appropriate amount of acupuncture stimulation, thereby preventing problems during competition.

Introduction：Respiratory failures are categorized into types I and II. To our knowledge, we report the first case of pulmonary rehabilitation in a patient with systemic sclerosis/polymyositis overlap syndrome who developed type II respiratory failure.Methods：The patient was a 77-year-old woman who had received treatment for systemic sclerosis and polymyositis at another hospital. When she visited our hospital to obtain a second opinion, she suddenly lost consciousness and underwent trachea intubation because of typeⅡrespiratory failure. She received physical therapy on the third day of hospitalization and underwent a tracheotomy on the 16th day. As her thoracic movement was markedly restricted, we started physical training. After she was weaned off from the ventilator on the 43rd day, we performed muscular strength training and aerobic exercise. No exacerbation of CO2 storage was observed even if chest motion training was performed. She was discharged on the 72nd day and advised to wear retina®．Administration of therapeutic drugs such as steroids was maintained at the same dose.Conclusion：Physical therapy, such as chest mobilization, was effective for marked restriction of chest movement in a patient who had both polymyositis and systemic sclerosis.

[Objective] The purpose of this cross-sectional questionnaire-based study is to investigate the challenges of adverse events during treatment by acupuncture and moxibustion to an athlete. [Methods] In total, 1,804 subjects, including athletes who participated in marathons and university athletes were enrolled in this study. The survey was conducted by distributing the questionnaire or via online questionnaire to the athletes who fit the criteria for the study. The questionnaires were collected after consent was received from the participants; online questionnaires were also collected. The questionnaire was examined for age, sex, and type of competition, purpose of the acupuncture treatment and the actual effects, and treated area, content of adverse event, number of times the subjects received acupuncture, and informed consent, and free description of adverse events.[Results] In total, 1,525 (84.5%) valid responses to the questionnaires were received. The survey analyzed 841 subjects (55.1%) who experienced acupuncture and moxibustion. The following responses about adverse events of acupuncture were obtained: "pain at time of needle insertion"; 17.0%, "subcutaneous-bleeding"; 10.1% and "pain and feeling of heaviness due to the needle": 10.0%, among others. For moxibustion, responses included "burns"; 5.9% and "malaise"; 5.8%, among others. In the free description, there were 17 descriptions of discomfort due to excessive stimulation and difficulty in movement during exercise. Of the questions regarding whether or not they received informed consent, 215 were received orally (25.6%), 34 were received in written form (4.0%), 99 were received both orally and in written form (11.8%).[Discussion and Conclusion] Acupuncture for athletes causes a certain rate of adverse events. It was suggested that guidelines for athletes to receive acupuncture safely and training and education for practitioners are important.

PURPOSE: Recent reports have posed doubts about the effect of preradiosurgical embolization in brain arteriovenous malformation (AVM) because it makes the planning of stereotactic radiosurgery (SRS) difficult and has the risk of recanalization out of the target. We investigated whether the performance and quality of embolization may influence the success of SRS based on a retrospective case cohort study. MATERIALS AND METHODS: Seventy-three patients who underwent embolization followed by SRS between 2003 and 2012 in eight institutes with neurointerventionists were considered. They were divided into the following two groups at 3 years of follow up after the final SRS: “successful occlusion group” (S group), with radiologically complete occlusion of AVM; and “non-successful occlusion group” (N group) with persistent remnant nidus or abnormal vascular networks. Patient background, AVM profile, embolization performance grade and complications were compared in each group. The quality of embolization was evaluated with the new grading system: embolization performance grade (E grade), specializing the achievement of nidus embolization. E grade A was defined as sufficient nidus embolization with more than half of the total number of feeders achieving nidus penetration. E grade B was defined as less than half achievement of nidus embolization, and E grade C was defines as failure to perform nidus embolization. RESULTS: Forty-three patients were included in the S group, and 29 patients were included in the N group. The size and Spetzler-Martin grade of AVM and the rate of diffuse type was higher in the N group without statistical significance. The embolization performance level according to E grade indicated a significantly higher rate of successful embolization with more than 50% of nidus penetration in the S group (P<0.001). This difference was also confirmed in the subanalysis for limited cases, excluding smaller AVMs with complete occlusion with SRS alone (P=0.001). CONCLUSION: The cause of the unsuccessful result of post-embolization SRS might be the large, diffuse angioarchitecture, but proper embolization with a high rate of nidus penetration to avoid recanalization is more important. Effective embolization is essential to contribute to and promote the effect of radiosurgery.
