The pollution of our environment by a variety of mutagenic agents has been at issue in the last few years. The herbicide 2, 4, 5-trichlorophenoxyacetic acid (2, 4, 5-T) has turned out to be a potent mutagenic agent. Therefore, we evaluated the cytogenetic effect of this compound on the human leukocyte in vitro. Chromatid aberrations were observed and it was found that their incidence increases in proportion to a rise in dose.
It has been claimed that the teratogenic effects of 2, 4, 5-T may be attributed to the presence of 2, 3, 7, 8-tetrachlorobenzo-p-dioxin (dioxin) as an impurity. The compound used in our study contained 0.09μg/g of dioxin. Although the level of contamination is low, the possible roleof dioxin cannot be ruled out. Nevertheless, the fact remains that the mutagenic effects of the compound now available are undeniable.

Objective: Similarity of drug names is one factor of dispensing incidents.  The aim of this study was to survey the relation between sensual similarities of drug names and the occurrence of taking errors for pharmacists who actually prepare medicine.
Methods: A pair of drugs (15 incident pairs and 104 control pairs) was displayed on a computer screen at random.  The subject’s task was to determine the sensual similarity of them.  Thirteen pharmacists who prepared these pairs and caused their incidents participated in the experiment.
Results: The result showed that the sensual similarity of drug names of incident pairs was found to be highly significant in comparison to one of the control pairs [p=0.026].  However, the similarity in incident pairs is not necessarily high.  It was suggested that the similarity of drug name was not the only factor of taking error.  Multiple linear regression analyses of the sensual similarity in control pairs were performed, in which 10 variables were reported as quantitative indicators of similarity of drug name and were able to be measured on the internet.  The correlation was good [R²=0.828].  However, this regression model was not useful when adjusting to incident pairs.  In incident pairs, the similarity value calculated by the regression model was lower than the measured sensual similarity.
Conclusion: The result suggested that measured sensual similarity includes other risk factors of taking error, such as appearance similarity and/or efficacy similarity and/or short distance arrangement.  It seemed that the pharmacist’s ability complicated the factor of taking error.

With aging of inpatients, the prevention of falls in old people is an important task nurses have to take upon themselves. In our hospital, we have been tackling the task in earnest by utilizing a fall prevention assessment score sheet. Our efforts have resulted in changes in the attitude of nurses as shown by a survey. (1) By working on the nursing plan with use of the fall prevention assessment score sheet, nurses have become alert to risk factors for falling. (2) They have realized that assistance suited to the needs of each patient is vital and that collaboration between patients, their families and hospital staff contributes to the prevention of falls greatly. (3) The use of an intervention manual has made it easy for nurses to cope with falls and consequent injury. (4) To share information of every factor for falling among the nursing staff has added greatly to the prevention of the recurrence of the fall.

Heberden's and Bouchard's nodes are clinical manifestations of osteoarthritis of the interphalangeal joints. Heberden's nodes typically affect the distal interphalangeal (DIP) and Bouchard's nodes, the proximal interphalangeal (PIP) joints of a fingers in patients with osteoarthritis. We describe osteoarthritis of the interpha­langeal joints in 3 women who were successfully treated with sokeikakketsuto. Case 1 : A 58-­year-­old woman presented with pain in the DIP joint of her left middle finger and was diagnosed with a Heberden's node. Case 2 : A 60­-year­-old woman presented with pain in the DIP joint of her left ring finger and was diagnosed with a Heberden's node. Case 3 : A 37­-year-­old woman presented with pain in PIP joint of her left ring finger and was diagnosed with a Bouchard's node. All women were successfully treated with sokeikakketsuto. In conclusion, sokeikakketsuto is a useful Kampo medication to treat mild-­to-­moderate pain secondary to bone, joint, or spinal conditions, as well as non-­steroidal anti­inflammatory drugs.

Purpose: This study aimed at identifying difficulties among post thoracic esophagectomy cancer patients during outpatient follow-up. Methods: Patients who had radical esophagectomy at a cancer center hospital in Japan were prospectively observed and were interviewed by a certified nurse assigned at esophageal surgical outpatient division. Their responses were documented in medical records and were analyzed by content analysis method. This study was approved by the study hospital's research ethics committee. Results: The data from 66 patients were obtained. Content analysis yielded 221 extracts, 25 categories, and 65 codes of difficulties, including: concerns or signs/symptoms associated with dietary intake, physical activity, and anxiety. Implications: The majority of post-thoracoabdominal esophagectomy patients experienced multiple dysfunctions and symptoms after discharge. The results underscore the significance of nurses' role in assessing and instructing patients to address these issues.

Background: Patients having thoracic esophagectomy, a standardized treatment for esophageal cancer patients in Japan, are known to have various postsurgical signs and symptoms for a period of time. The current status of nursing interventions at outpatients need to be clarified. Purpose: This study aimed at identifying the nurses' interventions for cancer patients at the outpatient setting who previously had thoracic radical esophagectomy. Methods: Patients who had esophagectomy at a cancer center hospital in Japan were prospectively observed and interviewed by outpatient nurses between January 2009 and December 2010. Their documented responses in medical record were prospectively investigated and were qualitatively analyzed via content analysis method. This study was approved by the study hospital's research ethics committee. Results and discussion: The data analysis of nursing interventions for 66 patients yielded 372 extracts, 12 categories, and 74 codes. Nurses were assessing patients' signs and symptoms affected by postsurgical changes, and were utilizing patients' active self-monitoring skills. The results also showed the significance of facilitating postsurgical recovery in relation to nutritional intake and physical activity in patients' daily life. Implications: Based upon the study results, the development of a systematic program is underway, which facilitates esophageal cancer patients' postsurgical recovery.

We present two cases of night sweats due to eiefuwa (deficiencies of nutrients and defenses) that were suc­cessfully treated with Kampo medicine. Case 1 was that of a 64-­year-­old man with perspiration during sleep and slight fever, and Case 2 was that of a 78­-year-­old man with perspiration during sleep and common cold­-like symptoms. Case 1 was administered with saikokeishito, and his symptoms quickly disappeared. Case 2 was administered with common cold drugs and saikokeishito initially, but the treatment was ineffective. Therefore, keishito was administered, and the patient's symptoms disappeared within 2 days. Sweating and common cold-­like symptoms were successfully treated with Kampo medicine for the diagnosis of eiefuwa. Further, we discuss the various descriptions of eiefuwa in the literature.

Poor eating is a life-threatening condition in senior citizens. Herein, we report a case of poor eating due to stomach yin deficiency (wei yin xu), which was successfully treated with bakumondoto. The patient was a 91-year-old woman who expected treatment for her poor food intake. She was diagnosed as poor eating with stomach yin deficiency and was administered with bakumondoto, which increased her food intake and weight. To treat poor eating with Kampo medicine, rikkunshito and various other Kampo drugs are commonly used. In this case, bakumondoto, which is usually used for respiratory diseases such as dry cough, was effective. Bakumondoto is useful for stomach yin deficiency of poor eating.

Carpal tunnel syndrome is a common condition caused by compression of the median nerve. Patients usually present with numbness and pain along the distribution of the median nerve in the hand. We report 2 cases of carpal tunnel syndrome successfully treated with kakkonto after their pattern diagnosis. We treated a 57-year-­old women and a 59-­year-­old man. Two patients presented with hand pain and numbness and were diagnosed with carpal tunnel syndrome. Kakkonto treatment was successfully in two cases. We observed that median nerve compression persisted in these patients even after disappearance of numbness and pain ; therefore, we recommended operative management. The 2 patients underwent an operation for carpal tunnel syndrome. Kakkonto can be considered useful palliative treatment before considering operative management for numbness and pain in the patients with carpal tunnel syndrome.
