Objective: To reveal the current use of medication notebooks in clinical practice and the differences in submission rates of medication notebooks among patients with different sociodemographic and medical characteristics.
Methods: We conducted a survey of the submission rates by studying the medication history, from June 19, 2014, to July 3, 2014.
Results: The overall submission rate of returning patients was 57.1% and the submission rate of patients who visit a single medical institution was significantly lower than patients who visit more than two (55.4% vs. 67.7%, p<0.001).  Multivariate logistic regression also indicated significant differences between the single and multiple medical institution visit group (adjusted OR=2.74 [95% CI: 1.93-3.89], p<0.001).  Submission rates for patients in their 20, 30, and 50 s who visit a single medical institution were lower than 40%.
Conclusions: To improve the usefulness of the community pharmacy and increase the submission rate, we need to increase awareness of the importance of medication notebooks among patients who visit a single medical institution.  Additionally, future studies need to focus on factors such as age-related issues that might affect submission rates.

Objective: In late 1970s, occupational exposure to antineoplastic agents was reported. Various countries, including Japan, have published guidelines for handling antineoplastic agents. Surveys are still being conducted to determine the levels of environmental exposure to antineoplastic agents at individual hospitals, and incidents of contamination are often reported. This study provides details regarding a literature survey conducted to evaluate the actual state of environmental contamination by antineoplastic agents and identify the related issues in order to promote environmental monitoring.Methods: The literature search was carried out from January 1, 1990 to July 31, 2017. PubMed and Ichushi-Web were searched with the following keywords: “antineoplastic agents,” “occupational exposure,” “surface contamination,” and “environmental monitoring.”Results: Following the literature search, 117 papers were included in the analysis. The findings showed that contamination by antineoplastic agents was widely reported in hospitals and places where antineoplastic drugs were not handled. The findings of this study regarding the actual state of environmental exposure are partial, as there is a lack of information on retail pharmacies and homes of outpatients who have received chemotherapy.Discussion: Therefore, further investigation is warranted. In addition, according to the current Japanese guidelines, published in 2015, environmental surveillance is not required to reduce contamination by antineoplastic agents. To promote environmental monitoring, we feel that it is necessary to determine a new survey method and the clarify optimum interval of environmental monitoring.

Objective: The utility of topotecan monotherapy for relapsed small-cell lung cancer (SCLC) after failure of amrubicin monotherapy has not been evaluated. We aimed to investigate the efficacy and safety of topotecan monotherapy in patients with relapsed SCLC after amrubicin monotherapy.Patients and Methods: We retrospectively analyzed data from 16 patients with relapsed SCLC who were treated with topotecan monotherapy after amrubicin monotherapy at our hospital.Results: The response rate, progression-free survival, and overall survival were 0%, 32.5 days (95% confidence interval [CI] = 18–51), and 112 days (95% CI = 55–267), respectively. The most common adverse events (grade ≥3) were leukopenia (31.3%) and thrombocytopenia (31.3%), followed by anemia, anorexia, edema, and lung infections.Conclusion: The efficacy of topotecan monotherapy for relapsed SCLC after amrubicin monotherapy is inconclusive. Therefore, further studies are warranted.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is useful for diagnosing mediastinal lymph node lesions. Cell blocks prepared from the needle washing fluid and flow cytometry of tissue samples are helpful in making the diagnosis, but the combination of both examinations is not routinely performed. A 77-year-old woman with fever, dyspnea, and anorexia was admitted to our hospital. Computed tomography showed enlarged mediastinal lymph nodes with calcification and left ureteral calculus; however, no focus of infection was identified. We suspected lymph node tuberculosis or malignant lymphoma, and EBUS-TBNA was performed to evaluate the mediastinal lymph node lesions. Because a cell block prepared from the needle rinse fluid was suspicious for malignant lymphoma, we changed the puncture needle from 22 G to 19 G and performed a second EBUS-TBNA. Diffuse large B-cell lymphoma (DLBCL) was diagnosed based on the results of flow cytometry of the EBUS-TBNA samples. Here we report this case of DLBCL in which mediastinal lymph node tuberculosis was suspected and cell block preparation and flow cytometry using EBUS-TBNA specimens were useful for the diagnosis.
