Objective The current standard treatment for locally advanced, unresectable stage III non-small-cell lung cancer (NSCLC) is concurrent chemoradiation therapy (CCRT) and durvalumab administration. Although reports have indicated that the prognosis of squamous cell carcinoma is poorer than that of adenocarcinoma, real-world data are currently inadequate. Methods The present study analyzed patients with stage III NSCLC who received CCRT at the study center between April 2018 and February 2022. ⋯ In the multivariate Cox proportional hazard analysis, the histological type was the only prognostic factor for the PFS (p<0.05) and OS (p<0.05). Conclusion The median PFS and OS were poorer in patients with squamous cell carcinoma than in those with stage III NSCLC treated with CCRT and durvalumab. The histological type was an independent factor affecting the PFS and OS.

Objective Adverse events such as bile leakage and bleeding are among the issues that need to be resolved in EUS-guided choledochoduodenostomy (EUS-CDS). To overcome this problem, we developed a new EUS-CDS technique using a 19-G Franseen needle without tract dilation. This study aimed to evaluate the safety and efficacy of the new EUS-CDS technique. ⋯ No early adverse events were observed. Conclusion The 19-G Franseen needle appeared to have a sufficient dilatory effect during puncturing. This EUS-CDS technique appears to be safe and effective and has the advantages of no adverse events and it is also a simplified procedure, which suggests its potential for widespread use in primary drainage.

Case Reports
Mild Encephalopathy/Encephalitis with Reversible Splenial Lesions after Amphetamine and Opioid Use.
A 47-year-old woman with a history of substance abuse, depression, and insomnia experienced a collapse. Upon arrival at the hospital, the patient displayed low systolic blood pressure, confusion, dehydration, and renal failure. Urine tests confirmed an amphetamine and opioid overdose. ⋯ Brain magnetic resonance imaging revealed abnormalities in the splenium of the corpus callosum, which later resolved. The patient's condition gradually improved without any specific treatment. This unique case represents the first report of mild encephalopathy/encephalitis with reversible splenial lesions associated with amphetamine and opioid use.

Objective Patients with rapidly progressive glomerulonephritis (RPGN) are at a high risk of progression to end-stage kidney disease (ESKD), requiring renal replacement therapy (RRT). The present study examined recent trends in the incidence of RRT due to RPGN in Japan. Methods The number of patients with incident RRT due to RPGN by sex from 2006 to 2021 was extracted from the Japanese Society of Dialysis Therapy Registry. ⋯ The SIRs decreased significantly in 2010-2013 relative to the first period (2006-2009) for both men [0.90 (95% confidence interval (CI) 0.85-0.96)] and women [0.92 (0.86-0.99)] but then increased to 1.01 (0.96-1.07) for men and 1.20 (1.13-1.27) for women in 2018-2021. In the older age groups (≥70 years old), age-specific incidence rates initially decreased in 2010-2013 but increased thereafter, peaking in 2018-2021. Conclusion From 2006 to 2021, the number of patients with incident RRT due to RPGN increased, with an increase in the age-specific incidence of RRT due to RPGN in the older age groups (≥70 years old), suggesting that the number of patients with incident RRT due to RPGN will continue to increase as the population ages in Japan.
