サケ科魚類の寄生虫，マスウキブクロセンチュウSalvelinema salmonicolaの新産地

山形県最上川水系小国川の支流である大横川で採集したヤマメOncorhynchus masou masou (Brevoort, 1856)の鰾と，島根県益田川で採集したヤマメの鰾から，マスウキブクロセンチュウ（鱒鰾線虫）Salvelinema salmonicola (Ishii, 1916)を得た。本線虫は両県から初記録である。Specimens of the cystidicolid nematode Salvelinema salmonicola (Ishii, 1916) were collected from the swim bladder of river-resident masu salmon, Oncorhynchus masou masou (Brevoort, 1856), in Yamagata and Shimane prefectures, Honshu, Japan. This nematode is reported herein for the first time from these two prefectures in Japan

Alveolar Soft Part Sarcoma: A Single-Center 26-Patient Case Series and Review of the Literature

Background. Alveolar soft part sarcoma (ASPS) is a rare tumor, and little information is available regarding its clinical features and appropriate treatments. Methods. A retrospective review of 26 consecutive ASPS patients (12 male, 14 female; mean age of 27 years) treated at our institution over 30 years (mean followup; 71 months) was performed. Results. The primary tumor developed in the lower extremity (12), trunk (8), and upper extremity (6), with an average size of 7.2 cm (range, 2–14 cm). The AJCC stage at presentation was IIA (7), III (3), and IV (16). Surgical excision was performed in 20 patients (R0 18, R1 plus radiotherapy 2) without local recurrence. Six patients (stage IIA 3/7, stage III 3/3) later developed metastases after an average period of 28.7 months. The median survival of the 26 patients was 90 months, with overall 5/10-year survival rates of 64%/48%. AJCC stage and tumor size were significant prognostic factors. Significant palliation and slowing of metastasis progression were achieved with gamma knife radiotherapy. Nine patients receiving chemotherapy showed no objective response. Conclusions. ASPS is indolent but has a high propensity for metastasis. Early diagnosis and complete excision of the small primary tumor are essential in the treatment of ASPS

Child-rearing Support with Collaboration between Municipalities and Hiroshima Universities: A Parent and Child Classroom to Support the Development of Language

本稿は、広島大学「地（知）の拠点大学による地方創生推進事業（大学COC 事業）」障がい者支援領域における、未就園児を対象とした子育て支援活動「のびのびくらぶ」の実施報告である。本活動は自治体と連携し、１歳半健康診査で「要経過観察」と判断された幼児とその保護者を対象としている。平成28年度は、計16回の活動を実施した。参加親子は各期５組、計10組20名であった。活動の企画・運営には本学学生ボランティア17名が参加した。参加した保護者10名のうち８名が「ことばの発達」に不安を抱いていると事前調査で回答していた。そのため、活動に絵本の読みあいを取り入れ、学生と参加児で自由に読みあうことを試みた。自治体との連携は、各期開始前後の打ち合わせ、毎回の活動後の振り返りおよび学生へのフィードバック、自治体主催の親子クラブへの学生参加、年度終わりの総括会議などを行った。This paper is a report of FY 2016 implementation of child rearing support activities for prekindergarden children in Hiroshima University“ Program for Promoting Regional Revitalization by Universities as Centers of Community : COC”. This activity cooperates with municipalities and covers infants and their guardians who have been judged to be “required follow-up observation” in medical examination for 1 year and a half. This activity is in collaboration with local governments, and infants and their parents who are judged to be “required follow-up” in health examination for 1 and half years are participating. In FY 2016, a total of 16 activities were conducted. Participating parents and children were 5 pairs in each period, totaling 10 pairs of 20 people. 17 student volunteers from our university participated in the planning and operation of activities. In the preliminary survey, eight of the 10 parents who participated answered that they were concerned about “children’s development”. For that reason, we took reading of the activity picture book and tried reading freely with students and children participating. Collaboration with municipalities was conducted before and after each activity, each activity was handed over to the students, and feedback was given to the students. Students also participated in parent-child clubs sponsored by municipalities and held general meetings at the end of the year

Treatment of a patient with skeletal open bite and temporomandibular joint disorders

The treatment of severe skeletal anterior open bite is extremely difficult in adults, and orthognathic surgery is generally selected for its treatment. We report the case of an 18-year-old adult patient with skeletal anterior open bite and temporomandibular disorders who was successfully treated using temporary anchorage devices. She had an open bite of -2.0 mm and an increased facial height. Miniplates were implanted in both the maxilla and mandible, and molar intrusion resulted in counterclockwise rotation of the mandible over a period of 12 months. After active treatment, her upper and lower first molars were intruded by approximately 2 mm and her overbite became +2.5 mm. Her retrognathic profile improved with counterclockwise rotation of the mandible. Orthodontic treatment aided with skeletal anchorage is beneficial for intrusion of bimaxillary molars in patients with anterior open bite
