Purpose: This retrospective study aims to evaluate the effectiveness and safety of morphine for the management of dyspnea in terminal cancer patients. Methods: 64 terminal cancer patients, who had morphine administered for dyspnea management, were investigated. Dyspnea was assessed daily on the numerical rating scale (NRS; 0-5) before and 48 hours after the administration, and at the point of dose modifications. Result: The medication period was 34.7 days and the daily dose of morphine was 93.0 mg. The mean NRS decreased from 3.5 to 1.6 (p<0.001). 46 patients (72%) were started with an oral administration of normal-release morphine when-required. The major side effects of morphine, such as hypoxemia or decrease in respiratory rate, were not observed. Conclusion: Morphine is effective and safe for the management of dyspnea even in terminal cancer patients with careful titration.

Many techniques have been developed to reduce the number of missed lesions during colonoscopy screening. Autofluorescence imaging (AFI) is one of the newly developed image-enhanced endoscopy (IEE) techniques, which functions similar to narrow band imaging (NBI) and flexible spectral imaging color enhancement (FICE), that can improve the detection and characterization of both polypoid and non-polypoid colonic neoplasms by enhancing their macroscopic features. We have previously reported that AFI, when used in combination with a transparent hood mounted on the tip of the endoscope to maintain distance from the colonic mucosa, results in the detection of approximately 1.6 times more colorectal neoplasms than conventional white light (WLI) colonoscopy. We have also revealed that AFI results in a higher flat neoplasm detection rate than WLI. Because the images of colorectal lesions visualized using AFI differ between histological lesion types, AFI also offers the possibility of differentiating neoplastic from non-neoplastic lesions. However, the difference between neoplastic and non-neoplastic lesions in the images generated using AFI relies on the density of the magenta coloring of the image and is therefore somewhat subjective. Recent studies suggest that NBI with magnification may be a superior modality for characterizing the neoplastic status of small colonic polyps. Although further developments are needed, the recent development of IEEs allows us to efficiently detect and differentiate colorectal neoplasms during colonoscopy screening. This article reviews the use of AFI in the diagnosis of colorectal neoplasms and discusses its advantages and limitations.

  In order to intervene in the management of pain of cancer from an early stage. Our palliative care team (PCT), including pharmacists, makes the ward rounds (screening rounds) of the patients receiving opioids at our hospital. The purpose of this study was to analyze the effects of screening rounds activity by the PCT and its current problems, and to explore how to resolve the problems. We retrospectively studied the records of 196 patients who had receivede interventions by the PCT, with regard to intervention status and prescription proposal (228 subjects) about drug therapy by us. Study groups were as follows: 103 patients to whom interventions were deliveed at the request of medical doctors (intervention request group) and 93 patients who had interventions by the PCT after PCT-screening rounds (screening group). PCT-screening rounds caused to increase the number of interventions by the PCT. After PCT-screening rounds, the cases of intervention started by the request of medical doctors, who had given no heed to PCT intervention, also increased in numher. In this study, some problems with palliative intervention were also brought to light. Even in the screening group where the PCT largely intervened, 33% of prescription proposal by the PCT was ignored. This problem may be, at least in part, due to inadequate communication between PCT and ward staff through an electronic medical recording card, leading to poor relationship between PCT and ward staff. In the future, the PCT needs to work cooperatively with ward staff through direct communication such as medical conference to perform better intervention.
