Abstract

Dynamic human movements are achieved by appropriate constraints on the degrees of freedom of the complex and flexible human body. The anatomy trains (ATs) theory explains such constraints with whole-body muscular connections called ATs. This paper proposes the design of a quasi-passive dynamic walker with whole-body viscoelastic connections inspired by the ATs theory and investigates the contributions of these long-distance connections to the achievement of gait. We designed a biped robot with a trunk and head, whose passive joints were supported by rubber fiber bands. The robot, named "PEARL III," is equipped with an antagonistic pair of McKibben pneumatic actuators for each leg at the human hamstring and rectus femoris positions. The most important feature of this robot is that fabric wires mechanically connect its rubber bands and actuators on the back side from the head to the foot, modeled after one of the human ATs, the superficial back lines (SBLs). In an experiment, PEARL III achieved 2D quasi-passive dynamic walking on an inclined plane by contracting and relaxing its actuators using periodic feedforward control. This result suggests that in both the robot and human cases, when a controller contracts the SBL only in the stance phase during passive dynamic walking, the SBL can achieve whole-body posture control and weight support. In addition, the SBL appears to achieve this function depending on their mode of attachment to bones and the presence or absence of antagonistic muscles (or ATs). In the future, by introducing various ATs into robots while recognizing the importance of the appropriate attachment of ATs and the presence of their antagonistic muscles (or ATs), we can expect similar effects in various 3D movements.

Abstract

ファーストバイト症候群（first bite syndrome：以下、FBS）は、食事開始時に耳下腺部痛を生じ数回の咀嚼により徐々に軽快することを特徴とする。手術既往や腫瘍性疾患がない FBS は特発性 FBS と分類される。特発性 FBS に対する治療法として少数ではあるが立効散の内服が報告されており、本症例でも立効散が奏功した。特発性 FBS の治療法は未確立であり、有害事象の少ない立効散は食事療法と並んでまず考慮すべき治療法であると考える。, First bite syndrome (FBS) is characterized by severe paroxysmal pain in the parotid region at the first bite of a meal, which gradually decreases as mastication continues. When FBS occurs with no history of head and neck surgery and no evidence of a tumor, it is classified as idiopathic. The effectiveness of Rikkosan has been reported by several studies, and we also experienced a case in which idiopathic FBS improved with Rikkosan. There is no established treatment method for idiopathic FBS. Rikkosan, which is associated with few adverse events, should be considered as a first-line treatment, along with diet therapy.

Abstract

Background: It is well known that chemotherapy for adolescent and young adult (AYA) patients with cancer can reduce fertility regardless of the regimen. A decline in fertility greatly affects the quality of life of cancer survivors in the AYA age group; however, few patients are thought to be receiving fertility preservation measures. Methods: A questionnaire survey was conducted to assess the current understanding and consideration of fertility among otorhinolaryngologists/head and neck surgeons who treat AYA patients with cancer, and to inform them of the guidelines for fertility preservation. A total of 275 otorhinolaryngologists/head and neck surgeons working at our hospital in Ehime, Japan, six neighboring universities, and their affiliated facilities were included in this study. The questionnaire was mailed and requested to be returned by fax. Twenty questions were asked about respondents’ years of experience as physicians, specialties, experience in medical care and chemotherapy for AYA patients with cancer, and knowledge and experience in fertility reduction measures. Results: Although 58.7% of the physicians were aware that cryopreservation of eggs and sperm prior to chemotherapy was recommended, only 7 out of 40 physicians (17.5%) had referred AYA patients with cancer to an appropriate medical facility (department) after obtaining informed consent for chemotherapy. Conclusions: Although fertility preservation has been discussed at professional conferences and seminars, consideration and actions in the field of otorhinolaryngology/head and neck surgery have not been sufficient. We hope that the results of this survey will help raise awareness of fertility preservation.
