Introduction: Stainless steel needles are mainly used in acupuncture treatment, but material considerations are crucial for patients with metal allergies. This report presents a case of acupuncture treatment administered without inducing allergic symptoms in the patient, achieved through effective collaboration with medical specialists.  Case: The patient was a 35-year-old woman. Complaints were menstrual symptoms, neck and lumbar pain, the former appeared after the birth of her second child at the age of 24, and the latter was felt chronically. She visited our department because she wanted to receive kampo medicine and acupuncture treatment. It was also reported that she had metal allergy symptoms. Therefore, after consultation with the allergist of our department, a full examination was requested at the dermatology department. In the meantime, our department suspected PMS, PMDD, and muscular or joint pain. First, we started acupuncture treatment using titanium press tack needles and resin contact needles to address muscular or joint pain, taking metal allergies into consideration. The frequency was once every two weeks. One month later, a patch test result was positive for nickel. Nevertheless, she still requested acupuncture treatment, and we consulted with the allergist regarding her case. Then, with her consent, the silicone-coated stainless steel acupuncture needles were inserted into the distal part of the limbs and remained in place for 15 min. During this time, we observed her skin and instructed her to closely monitor it and report any changes at her next visit. From the fifth treatment onward, additional acupuncture needles were placed in the neck and lumbar region, all without any allergic symptoms being observed.  Discussion and Conclusion: In this case, acupuncture treatment was performed safely in the medical cooperation. In the future, we would like to further examine the establishment of acupuncture treatment with high safety for patients with metal allergy symptoms and collaboration with medical specialists.

[Introduction] The effects of combining acupuncture and kampo medicine on in vitro fertilization (IVF) outcomes is unclear. Therefore, we aimed to investigate their combined effects on promoting conception in patients with multiple IVF attempts.[Methods] Participants with at least two IVF attempts who gave informed consent were included in this study. Administering acupuncture and kampo medicine, the study was conducted across three facilities from 2013 to 2017 using a case series design． Case 1: A 40-year-old woman presented after 13 months of infertility, having experienced a natural conception and subsequent miscarriage 10 months prior, which led to IVF. After a second embryo transfer, she miscarried again 3 months before visiting. She began kampo medicine and acupuncture for support in our department. Case 2: A 46-year-old woman with a 36-month infertility history did not achieve pregnancy after three IVF cycles． Case 3: A 37-year-old woman with a 20-month infertility history failed to conceive after two IVF attempts． Case 4: A 26-year-old woman, new to infertility treatment, received acupuncture for fertility preservation, experiencing headache, shoulder stiffness, and widespread pain. Case 5: A 38-year-old woman with a 108-month infertility history suffered from shoulder stiffness due to prolonged IVF therapy. The main outcome measured was pregnancy. Standard acupuncture points utilized included L14 (Hegu), CV12 (Zhongwan), CV7 (Yinjiao), ST27 (Daju), ST29 (Guilai), BL18 (Ganshu), BL20 (Pishu), BL23 (Shenshu), BL33 (Zhongliao), SP10 (Xuehai), ST36 (Zusanli), and SP6 (Sanyinjiao)． [Results] Four out of five participants achieved pregnancy． [Discussion] Our findings reveal a positive effect of combining acupuncture and kampo medicine on enhancing pregnancy rates in patients undergoing multiple IVF treatments, suggesting clinical effectiveness in fostering an appropriate environment for conception．

Low back pain is ranked number one burden of disease and a symptom that afflicts people worldwide. Although many cases of low back pain are considered non-specific, there is no unified agreement on the classification method. Furthermore, the biopsychosocial model is used as an interpretation model for understanding low back pain. Therefore, the effectiveness of acupuncture treatment for low back pain must be verified while clearly identifying the perspective from which low back pain is viewed and considering psychological factors. In this symposium, lectures were given by Akasaka, Inoue, Kikuchi, and Kondo. Akasaka explained specific and non-specific low back pain from the perspective of a physical therapist. Specifically, he presented the classification of low back pain based on structural anatomy of the musculoskeletal system such as facet joint, myofascial, and intervertebral discogenic pain as non-specific low back pain, and explained about the effectiveness of physical therapy. Inoue presented the results of randomized controlled trials of acupuncture treatment in patients with low back and lower limb pain that he had conducted. He also discussed the importance of needling at specific points such as the erector spinae group of muscles after carefully palpating these points. Furthermore, Inoue outlined the effects of needling along nerve pathways in patients with lower limb symptoms. Kikuchi reported the results of a retrospective observational study on the effectiveness of acupuncture in treatment of low back pain by classifying patients according to their movement reproducibility. He well stated that patients with movement reproducibility showed more improvement in low back pain-related quality of life. Kondo elaborated on how psychosocial factors in patients with low back pain could affect the effectiveness of acupuncture treatment. He also reported that the less catastrophic thinking about pain was, the greater effectiveness of acupuncture treatment was. In addition, Kondo also indicated that the lower risk on the Subgrouping for Targeted Treatment Back Screening Tool was, the more easily reduced pain was.We hope that the content of this symposium would serve as a valuable resource for clinical, research, and educational activities starting tomorrow.

Introduction: Unidirectional porous β-tricalcium phosphate (UDPTCP) consists of a novel porous artificial bone that is structurally different from conventional artificial bone comprised of spherical porous β-tricalcium phosphate (SPTCP).Case presentation: We present our first four clinical cases of opening-wedge high tibial osteotomy (OWHTO) using UDPTCP and SPTCP together. The patients’ mean age was 54.5 ± 5.9 years, and the mean observation period was 20.8 ± 2.8 months. In OWHTO, two wedge shaped pieces of UDPTCP and SPTCP were cut to fit the gap and implanted parallel to each other in the anterior and posterior parts, respectively. We evaluated the correction loss and bone remodeling for UDPTCP and SPTCP over time using radiography and computed tomography, and evaluated the clinical outcomes.Conclusion: There was no correction loss reported in any case, and early bone remodeling was observed with UDPTCP. All patients achieved satisfactory clinical results with no adverse events.
