A Case Report of Giant Mesenteric Malignant Lymphoma Requiring Emergency Surgery Due to Intestinal Necrosis
No full textJournal Article症例は76歳の男性で，食思不振，腹部膨満感を主訴に受診した．初診時，腹部に圧痛はなかった．血液検査にて，炎症反応，LDHの軽度上昇と，可溶性IL-2レセプターの著明な上昇を認め，腹部CTにて，下腹部に不整で不均一に造影される巨大な腫瘤を認めた．上腸間膜動静脈を含む腸間膜が腫瘤に圧迫され，sandwich signを呈していたため，腸間膜悪性リンパ腫と診断した．造影CTにて小腸に虚血を疑わせる所見があり，入院後，腹痛が増悪したため緊急手術を行った．回腸が20 cmにわたって壊死を起こしており，腫瘍とともに回盲部，回腸約100 cmを切除した．病理診断は，diffuse large B-cell lymphomaであった．同疾患はガイドラインに従うと，化学療法，放射線療法が基本であるが，本例のように，腫瘍の巨大化により腸管の血流障害を引き起こし，緊急手術要する必要が生じることがある．journal articl
A Study on Guidance before the Bed Bath Care in Fundamental Nursing Practice ─ Focused Information, Decision Making and Teaching Behavior of Nursing Teachers ─
No full textJournal Article【背景・目的】 臨地実習における教員の指導行動は看護ケア及び学習に重要である．本研究では，基礎看護学実習で学生が日常生活援助技術を実施する前の指導において，教員が着目している情報と，指導における教員の判断および指導行動を明らかにした．
【対象と方法】 臨地実習における援助実施前の学生に対する模擬指導場面を設定し，看護教員10名が模擬指導を行う場面をVTRに撮ったのちにインタビューを行った．VTRの言動と逐語録から，指導時に着目している情報，その際の判断の内容，模擬学生に対する指導行動を抽出しカテゴリ化した．
【結 果】 指導時に着目している情報は「学生が立案した援助計画の記載内容」など3つ，判断は「援助の必要性と援助項目の選択の適切さの吟味を促す指導に関する判断」など5つ，指導行動は「目標設定や援助項目の選択理由などに関する指導行動」など6つが抽出された．
【結 語】 教員は学生が的確に援助ができるように多くのことに着目し指導時の判断から指導を行っていた．また，指導の際には学生の心情に配慮しつつ指導が行われていた．journal articl
Wearable Cardiac Monitor Used by Two Rescue Work Trainees at a Simulated High Altitude to Prevent Excessive Work Load
No full textJournal ArticleWe had previously experienced a case involving prolonged cardiopulmonary resuscitation (CPR) on Mt. Fuji (3,776 m), demanding strenuous work by the rescuers. The objective of this study was to examine the effectiveness of a wearable electrocardiogram (ECG) with 10 electrodes for the assessment of cardiac condition during exercise at hypobaric hypoxic environment. The traces of ECG during CPR action were obtained in a hypobaric chamber with barometric pressure adjusted to be equivalent to 3,700 m above sea level (630-640 hPa). Two volunteers performed CPR with or without breaths using a CPR mannequin. In a 3,700-m-equivalent environment, the percentage of recordings with clear signal qualities were 26% at V1 position, and 31% at V4 position, respectively. Although wearable ECG monitoring is still under development, removing electromyogram artefact may improve the signal quality and make the wearable 12-lead ECG monitoring useful in preventing cardiac problems at high altitudes and in wilderness environments.journal articl
Evaluating the Certification Examination for Medical Physicists in Japan Via Questionnaire Survey and Access Analyses
No full textJournal ArticleBackground & Aims: With the development of radiology, the demand for medical physicists is increasing, and the training of new medical physicists is becoming a necessity. Although a few questionnaire surveys regarding medical physicists and medical physicist training courses have been conducted, no survey reports have yet been conducted on examinees. This study is the first survey of general examinees.
Methods: Gunma University has a webpage for test preparation, and we conducted a survey on examinees using this page, through a questionnaire and access analyses.
Results: Approximately 80% of the users qualified as technologists. Considering the percentage of users by region, the number of medical physicists and accredited facilities were strongly correlated. The proportion of females was extremely low. Exam papers on “science and technology” and “radiation physics” were accessed more than those on “medical and biology” field. Thus, physics may be a shortcoming of many examinees; science and engineering majors were less likely to take exams and have lower pass rates.
Conclusion: Recruitment and provision of learning environments for science and engineering graduates are required. To increase the number of students, while improving the quality of medical physicists, it is necessary to investigate current conditions of students in greater detail.journal articl
