		                        			 Objective:
		                        			While antipsychotics are necessary for relapse prevention in the treatment of schizophrenia in general, some minority of patients may be maintained without continuous antipsychotic treatment. However, the characteristics of such patients are not well known and previous reports have not evaluated key elements such as physical comorbidities and functioning. 
		                        		
		                        			Methods:
		                        			Among 635 patients with schizophrenia who participated in a 12-year follow-up, those who were maintained without antipsychotic treatment for at least one year after the study were investigated. The patients underwent comprehensive assessments, including Positive and Negative Syndrome Scale (PANSS) for psychopathology, Cumulative Illness Rating Scale for Geriatrics (CIRS-G) for physical comorbidities, and Functional Assessment for Comprehensive Treatment of Schizophrenia (FACT-Sz), Barthel Index, and EuroQoL five dimensions (EQ5D) for function. 
		                        		
		                        			Results:
		                        			Six patients were included (mean ± standard deviation age, 66.8 ± 17.4 years; 4 inpatients). The four inpatients were old (77.8 ± 4.8 years) and chronically ill (duration of illness, 49.3 ± 12.5 years) with a high PANSS score (total score, 118.0 ± 9.8; negative syndrome subscale, 41.3 ± 6.9), low functioning (FACT-Sz, 9.8 ± 3.6; Barthel Index, 8.8 ± 9.6), and serious physical comorbidities (CIRS-G, 15.5 ± 1.1). By contrast, the two outpatients were relatively young (45.0 ± 12.0 years) and clinically in good condition (PANSS total score, 44.5 ± 0.5; Barthel Index, 100 for both; EQ5D, 0.85 ± 0.04). 
		                        		
		                        			Conclusion
		                        			Although the number is limited, two types of patients with schizophrenia were identified who were free from ongoing antipsychotic treatment; 1) older chronic inpatients with serious physical comorbidities, and 2) younger outpatients with milder impairments. Future explorations are needed to identify those who will be successfully withdrawn from continuous antipsychotic treatment.

		                        			Objective: The Risk Minimization Plan is developed in the Risk Management Plan (RMP), patient information materials are sometimes prepared as Additional Risk Minimization Activities (ARMA). On the other hand, there are many patient information materials that are not prepared as RMP materials, but are prepared independently by pharmaceutical companies and are actually used to provide information to patients. However, there is no detailed report on the differences between them. Therefore, in this report, we investigated for description of Important Identified Risks (IIRs) and Important Potential Risks (IPRs) in patient information materials.Methods: The previously published RMP of 588 drugs were obtained on October 1,2020, and used in analysis. We surveyed the description of IIRs and IPRs in patient information materials, and compared patient information materials based on ARMA in the RMP (patient information materials as RMP materials) and patient information materials developed independently by pharmaceutical companies that are not based on ARMA in the RMP (patient information materials as not RMP materials).Results: Of the 588 drugs, 454 drugs had patient information materials. In addition, 241 drugs had patient information materials as RMP materials. One thousand fifteen of the 1,577 IIRs were listed in the patient information materials as RMP materials (64.4%listing rate). One hundred sixty-six of the 724 IPRs were listed in the patient information materials as RMP materials (22.9%). On the other hand, 700 of the 1,131 IIRs were listed in the patient information materials as not RMP materials (61.9% listing rate). Ninty one of the 447 IPRs were listed in the patient information materials as not RMP materials (20.4%).Conclusion: It was found that there was no difference in the description of IIRs and IPRs between patient information materials as RMP materials and patient information materials as not RMP materials.

		                        			 Background/Aims:
		                        			Endoscopic ultrasound (EUS)-guided fine needle aspiration (FNA; EUS-FNA) allows for diagnostic tissue specimens from various regions to be analyzed. How-ever, diagnosing recurrent pancreaticobiliary cancer after surgery is sometimes difficult. We evaluated the efficacy of EUS-FNA in the diagnosis of local recurrence of pancreatico-biliary cancer and analyzed the factors associated with falsenegative results.  
		                        		
		                        			Methods:
		                        			Fifty-one consecutive patients who underwent EUS-FNA due to suspected recurrence of pancreaticobiliary cancer after surgery in an academic cen-ter were retrospectively analyzed. The criteria for EUS-FNA were a resected margin or remnant pancreas mass, round swollen lymph node (≥10 mm in diameter), and soft-tissue enhancement around a major artery. Patients with suspected liver metastasis or malignant ascites were excluded.  
		                        		
		                        			Results:
		                        			Thirty-nine of the 51 patients had pancreatic cancer; the remaining 12 had biliary cancer. The target sites for EUS-FNA were the soft tissue around a major artery (n=22, 43%), the resected margin or remnant pancreas (n=12, 24%), and the lymph nodes (n=17, 33%). The median size of the suspected recurrent lesions was 15 mm (range, 8 to 40 mm). The over-all sensitivity, specificity and accuracy of EUS-FNA for the diagnosis of recurrence was 84% (32/38), 100% (13/13), and 88% (45/51), respectively. FNA of the soft tissue around major arteries (odds ratio, 8.23; 95% confidence interval, 1.2 to 166.7; p=0.033) was significantly associated with a falsenegative diagnosis in the multivariate analysis.  
		                        		
		                        			Conclusions
		                        			EUS-FNA is useful for diagnosing recurrent cancer, even after pancreaticobiliary surgery. The diagnoses of recurrence at soft-tissue sites should be interpreted with caution.

		                        			BACKGROUND/AIMS: We applied a back light system (BLS) with a magnifying glass to improve the ability to assess the adequacy of specimen sampling using endosonography. We conducted this study to evaluate the efficacy of the BLS in sampling of specimens by endoscopic ultrasound-guided fine needle aspiration of solid pancreatic masses. METHODS: This was a prospective, randomized, crossover, single-center clinical trial. An endosonographer evaluated adequacy on gross visual inspection and identified whitish specimen sampling sites with and without the BLS according to a randomization sequence in the first and second passes with a 25-G needle. On cytological evaluation, the presence of well-defined pancreatic ductal epithelium was evaluated by a cytopathologist who was blinded to any clinical information. RESULTS: A total of 80 consecutive patients were eligible during the study period. Adequacy was observed for 52 specimens (65%) with the BLS and 54 (68%) without the BLS (p=0.88). In assessment of specimen adequacy on gross examination, only fair agreement was observed both with and without BLS (kappa score 0.40 and 0.29, respectively). CONCLUSIONS: The BLS did not influence the ability to identify specimen sampling sites or reliable assessment of specimen site adequacy using gross visual inspection.

		                        			BACKGROUND/AIMS: This study aimed to examine the diagnostic ability of endoscopic ultrasonography (EUS) for major vascular invasion in pancreatic cancer and to evaluate the relationship between EUS findings and pathological distance. METHODS: In total, 57 consecutive patients who underwent EUS for pancreatic cancer before surgery were retrospectively reviewed. EUS image findings were divided into four types according to the relationship between the tumor and major vessel (types 1 and 2: invasion, types 3 and 4: non-invasion). We also compared the EUS findings and pathologically measured distances between the tumors and evaluated vessels. RESULTS: The sensitivity, specificity, and accuracy of EUS diagnosis for vascular invasion were 89%, 92%, and 91%, respectively, in the veins and 83%, 94%, and 93%, respectively, in the arteries. The pathologically evaluated distances of cases with type 2 EUS findings were significantly shorter than those of cases with type 3 EUS findings in both the major veins (median [interquartile range], 96 [0–742] µm vs. 2,833 [1,076–5,694] µm, p=0.012) and arteries (623 [0–854] µm vs. 3,097 [1,396–6,000] µm, p=0.0061). All cases with a distance of ≥1,000 µm between the tumors and main vessels were correctly diagnosed. CONCLUSIONS: Tumors at a distance ≥1,000 µm from the main vessels were correctly diagnosed by EUS.

		                        			BACKGROUND/AIMS: Tacrolimus is effective for refractory ulcerative colitis in adults, while data for children is sparse. We aimed to evaluate the effectiveness and safety of tacrolimus for induction and maintenance therapy in Japanese children with ulcerative colitis.METHODS: We retrospectively reviewed the multicenter survey data of 67 patients with ulcerative colitis aged < 17 years treated with tacrolimus between 2000 and 2012. Patients’ characteristics, disease activity, Pediatric Ulcerative Colitis Activity Index (PUCAI) score, initial oral tacrolimus dose, short-term (2-week) and long-term (1-year) outcomes, steroid-sparing effects, and adverse events were evaluated. Clinical remission was defined as a PUCAI score < 10; treatment response was defined as a PUCAI score reduction of ≥ 20 points compared with baseline.RESULTS: Patients included 35 boys and 32 girls (median [interquartile range] at admission: 13 [11–15] years). Thirty-nine patients were steroid-dependent and 26 were steroidrefractory; 20 had severe colitis and 43 had moderate colitis. The initial tacrolimus dose was 0.09 mg/kg/day (range, 0.05–0.12 mg/kg/day). The short-term clinical remission rate was 47.8%, and the clinical response rate was 37.3%. The mean prednisolone dose was reduced from 19.2 mg/day at tacrolimus initiation to 5.7 mg/day at week 8 (P< 0.001). The adverse event rate was 53.7%; 6 patients required discontinuation of tacrolimus therapy.CONCLUSIONS: Tacrolimus was a safe and effective second-line induction therapy for steroid-dependent and steroid-refractory ulcerative colitis in Japanese children.
