Case Reports
A Case of Bile Duct Mixed Neuroendocrine-nonendocrine Neoplasm with a Complete Response to Chemoradiotherapy.
The incidence of neuroendocrine carcinomas arising from the bile duct is low, and that of mixed neuroendocrine-non-neuroendocrine neoplasms (MiNENs) is even lower; therefore, there is no standard treatment for MiNENs. Choosing the appropriate treatment in clinical practice is difficult. We herein report a case of unresectable extrahepatic bile duct MiNEN in a 66-year-old man who received curative chemoradiotherapy and achieved a complete response, remaining recurrence-free for 2.5 years. We consider the findings of this case to be valuable in selecting a treatment strategy for unresectable bile duct MiNENs.

Comparative Study
A Comparison of Alanine Aminotransferase Normalization between Pemafibrate and Bezafibrate in Patients with Nonalcoholic Fatty Liver Disease.
Objective Pemafibrate is a recently developed selective peroxisome proliferator-activated receptor alpha modulator that can improve alanine aminotransferase (ALT) levels in patients with nonalcoholic fatty liver disease (NAFLD). However, the effectiveness of ALT normalization with pemafibrate and bezafibrate, a traditional fibrate, has not been compared. Methods In this retrospective study, we compared the effects of pemafibrate and bezafibrate on ALT normalization in patients with NAFLD. ⋯ The ALT normalization rate at 12 months was significantly higher in patients treated with pemafibrate than in those treated with bezafibrate (p=0.01). Pemafibrate, when compared with bezafibrate, was shown to be a significant factor for ALT normalization in a multivariable analysis with an adjusted odds ratio (95% confidence interval) of 13.8 (1.6-115, p=0.01). Conclusion Pemafibrate is effective in ALT normalization in patients with NAFLD and may be used as a treatment for NAFLD.

Clinical Characteristics of Patients with Cryptococcal Meningitis in Hokkaido: A Case Series.
We retrospectively reviewed the medical histories, examination results, treatments, and prognoses of nine patients with cryptococcal meningitis who were diagnosed and treated at Hokkaido University Hospital and its affiliated hospitals over the past 10 years. Cryptococcal meningitis can develop even in immunocompetent hosts, and its prognosis is poor owing to diagnostic difficulties and delayed treatment. Although liposomal amphotericin B and oral 5-fluorocytosine are standard therapies, voriconazole or intraventricular administration of amphotericin B may also be considered treatment options for refractory patients. Some patients develop delayed exacerbations owing to immunological mechanisms that require steroid therapy.

Pregnancies with chronic kidney disease (CKD) and high disease activity in rheumatic diseases are high-risk events with adverse outcomes for both the mother and fetus. We herein report a 35-year-old woman with juvenile idiopathic arthritis (JIA), amyloid A (AA) amyloidosis related to JIA, and CKD stage G4A2 who wished to have children. She achieved a successful pregnancy, even in the presence of these multiple risk factors, using tocilizumab to control the disease activity of JIA and AA amyloidosis, along with antihypertensive drugs to control her blood pressure before and during pregnancy.

Case Reports
Primary Peritonitis due to Group A Streptococcus Successfully Treated with Intraperitoneal Drainage.
A 42-year-old woman was admitted to our hospital because of lower abdominal pain and diarrhea. Although the initial symptoms and imaging findings were similar to those of acute enteritis, blood and ascites cultures led to the diagnosis of primary peritonitis caused by group A Streptococcus. ⋯ In the present case, intraperitoneal drainage was effective for avoiding surgery. We suggest that intraperitoneal drainage is effective for the treatment of this disease.
