Background: Despite an increasing awareness of the risk of medical errors, few data sources are available to highlight the characteristics and patterns of medical errors in the clinical management of rheumatoid arthritis (RA). The present study aimed to evaluate medical malpractice claims associated with the management of RA and other atltoimmune connective tissue diseases (ACTDs). Methods: We analyzed 38 ACTD-associated closed claims extracted from a total of 8530 claims processed between July 2004 and June 2014 by the Tokyo headquarters office of Sompo Japan Nipponkoa Incorporated, a leading malpractice insurer in Japan. Results: RA was the most common ACTD assessed in this study, accounting for 20 cases. Although the male-to-female ratio among these cases was 5:15, in accordance with the general demographic distribution of RA, the proportion of patients older than 60 years (77.8%) was relatively high as the general range of RA susceptibility is 30-50 years. The analysis of allegation types among RA cases revealed statistically significant differences from non-RA cases (Fisher's exact test) as well as the following key findings: diagnosis-related allegations were absent (P 〈 0.01 ), whereas medication-related allegations were distinctively common (P=0.02). Clinical processes related to the assessment process were most vulnerable to breakdown and leading to negligence identified with subsequent medication-related allegations, particularly among RA cases. Conclusions: The characteristics of malpractice claims associated with RA management, including the high frequency of medication-related allegations, breakdowns in the assessment process, and high claim numbers among patients older than 60 years, suggest the importance of caution exercised by physicians when administering immunosuppressants for the clinical treatment of RA.

BACKGROUND Chemotherapy is a standard strategy for stage IV gastric cancer ***, some cases cannot undergo conversion surgery because of their frailty,even if the patients had response to chemotherapy. For these patients, local tumor progression is a problem. We report here the case of a patient whose residual gastric cancer was resected through endoscopic submucosal dissection(ESD)after concomitant chemotherapy for metastatic gastric *** SUMMARY An 85-year-old male complained of difficulty swallowing, and examination revealed gastric cancer with multiple liver metastases. Although he received concomitant chemotherapy, a residual tumor was observed in the primary lesion while the metastatic lesions disappeared completely. Conversion surgery was considered optional treatment; however, he could not undergo that because of advanced age and comorbidities. Thus, we performed ESD to treat the residual tumor. As a result, we resected the residual lesion completely. The patient has been alive for 29 mo since ESD, without *** We achieved local control using ESD, and these findings may provide therapeutic improvements both in local control and patient survival outcomes.
