Objective: The benefits of combining cancer screenings with clinical surveys have become increasingly obvious as cancer morbidity and mortality have steadily increased. This paper discusses a study on the current status of and issues surrounding breast cancer screening in a clinical survey. The study also investigated the patients' awareness of the benefits of breast cancer screening. A secondary aim of the study was to promote mammographic screening.;Subjects and Methods: During the 72 months between April 1999 and March 2005, a total of 36,505 women underwent clinical surveys in our hospital. In October 2002, mammographic examination was included as an optional part of the routine physical examination. We evaluated the results of breast cancer screening with or without mammographic examination and used a questionnaire to investigate the patients' awareness of the benefits of breast cancer screening.;Results: Compared with the pre-2001 results, the detection rate of breast cancer significantly increased after 2003 when physical examination was combined with mammographic examination. Our study also found that both elderly patients and those residing in the suburbs of Sapporo City tended to choose physical examination alone rather than combining it with mammographic examination. An analysis of the questionnaires collected from these patients indicates they had a poor understanding of and lacked awareness of the benefits of mammographic examinations during breast cancer screenings.;Conclusions: The inclusion of mammographic screenings with clinical surveys was found to be significantly useful in the detection of breast cancer. Further continued education is needed for women, particularly the elderly and residents in the suburbs, so they understand the benefits of breast cancer screening by mammographic examination for the early detection of breast cancer and, consequently, decreased mortality of the disease.

A 79-year-old woman with left hemiplegia and loss of consciousness was transferred to a previous hospital. She underwent a CT-scan of the aorta and CT-perfusion of the brain and was diagnosed with Stanford type A acute aortic dissection complicated with cerebral malperfusion with narrowing of the right carotid artery region. She was transferred to our hospital and underwent emergency ascending aorta replacement. Preoperative CT perfusion findings predicted improvement of neurological symptoms after aortic repair, and she had no neurological complications postoperatively.

Introduction: Naloxone administration is considered for severe overdose symptoms during opioid administration. However, the actual status of naloxone administration during cancer pain treatment is unclear. Objective: To explore the frequency of patients who received naloxone for opioid overdose symptoms and the factors associated with naloxone administration. Methods: A retrospective study, naloxone use was selected from cancer patients receiving opioids at our hospital from 2014–2022, excluding those undergoing surgery or after tests and procedures. The type of opioid used, route of administration, dose and naloxone administration method, dose, and post-administration response were examined. Results: 18 patients (0.10%) were extracted, opioids at the time of naloxone administration were 81.6 (21–750) mg/day of oral morphine equivalent, and patient status (with duplicates) were: 8 patients with impaired renal function, 7 patients with clinical prognostic weeks, 4/3 patients after opioid change/increase. Discussion: Patients treated with naloxone are more likely to have impaired renal function, terminal stage, and after opioid change/increase, which may be risk factors that require attention for the emergence of overdose symptoms.

In accordance with the new model-core-curriculum for medical education, the current status of education about the science of radiation health was surveyed in all medical schools in Japan. Among the four learning points related to the “Biological effects of radiation and radiation hazards” , about half of the schools covered issues on “radiation and human body” and the “effect of medical radiation exposure” in one, or less than one, 60-minutes class, but did not touch on “radiation risk communication” and “radiological disaster medicine” . A significant deviation of human resources was also observed between schools. Learning tools such as presentation files and video content were preferred as education support materials. Therefore, development and distribution of the learning tools, especially in “radiation risk communication” and “radiological disaster medicine” , may be a first step to promoting high-quality education on the science of radiation health risk in each school’s curriculum.
