    Although chronic constipation is highly prevalent, its definition remains unclear. Therefore, the prevalence varies depending on reports, and the understanding of actual situations is unclear. Hence, we performed an internet survey on constipation among the Japanese general population to study the background factors and actual situations. Preliminary study on the awareness of constipation was conducted among 10000 people in which 9523 of them was asked if they had constipation at the time of the survey. In this population, 51.5% realized that they had constipation. Multivariate analysis showed the significant association of constipation to age, sex, and past histories or complications of diabetes, hemorrhoids, and cerebrovascular diseases. In a main research composed of 3000 general Japanese population, approximately 30.9% of the subjects reported the use of laxatives to treat constipation, and 43.8% of them were found to use irritant laxatives. Moreover, 67.5% of the subjects purchased laxatives at a pharmacy. The frequency of bowel movement less than 3 times per week was manifested in 36.3% of the subjects, and more than once per week in 21.4%. The percentage of hard (Bristol Stool Form Scale [BSFS] Type 1-2), normal (BSFS Type 3-5), and diarrhea stools (BSFS Type 6-7) was 33.1%, 60.0%, and 6.9%, respectively. The quality of life (QOL) of the subjects with hard and diarrhea stools evaluated by SF-8 was significantly lower than that of those with normal stools. Furthermore, the actual monthly cost for the therapeutic drugs used for treating constipation was less than 1000 yen in 75% of the subjects. Analysis of the IBS-QOL-J indicated that the ≥5000 yen payable group had the lowest satisfaction of defecation among the study groups. At present, many Japanese patients with constipation have not been receiving enough treatment for constipation. Therefore, appropriate medication by physicians as well as instruction to patients is required.

    A 52-year-old woman with epigastralgia and abdominal discomfort was admitted to our hospital. The abdominal CT scan showed that she had intestinal obstruction and peritoneal dissemination. Colonoscopy also revealed a submucosal tumor around the orifice of the appendix. Moreover, histological examination results indicated signet ring cell carcinoma. She was then treated with modified FOLFOX chemotherapy;however, the disease condition progressed after an 8-course treatment, and she died 12 months after the chemotherapy was initiated.

    Serous cystic neoplasms (SCNs) of the pancreas are slow-growing benign tumors. They are mostly monitored without surgical management. Solid SCN is rare and differentiating it from hypervascular tumors of the pancreas using preoperative imaging may be difficult. A 69-year-old woman was referred to our department for surgical treatment of an enlarged pancreatic tail tumor with a size of 22mm based on the abdominal computed tomography (CT). At the age of 60, she underwent thyroidectomy for papillary thyroid carcinoma and mastectomy for breast cancer. Initially, consecutive annual CT examinations did not show signs of recurrence. However, after 9 years, a hypervascular pancreatic tumor was detected and assumed to be either a neuroendocrine tumor or metastasis. The patient underwent distal pancreatectomy, and the resected specimen was histopathologically diagnosed as solid SCN of the pancreas. Before being referred for pancreatic resection, this patient had been followed up with serial annual CT examinations for over 9 years after a previous malignant disease. Retrospectively, the abdominal CT scans showed that the pancreatic tumor already existed 5 years ago and had gradually increased in size thereafter. In this case report, we focused on the characteristics of solid SCN to address the difficulty in diagnosing this rare malignancy.

    This case report presents two males with drug-induced liver injury acquired from working at a glass factory dealing with silica and 2,2-dichloro-1,1,1-trifluoroethane (HCFC-123). Within one month of work, both patients presented with fever, icterus with liver dysfunction, and eosinophilia. Case 1 had experienced recurrence of symptoms twice while working and showed positive results for the drug-induced lymphocyte stimulation test (DLST). Meanwhile, case 2 was diagnosed by liver biopsy and clinical course but was negative for DLST. Hazard of exposure to non-crystalline silica is low, but drug-induced liver injury after exposure to HCFC-123 has been reported. Allergic liver injury is also caused by chemical substances;however, the insight into whether this injury is caused by exposure to silica or HCFC-123 remains unclear. Further studies are required to examine the influence of silica and HCFC-123 on drug-induced liver injury among glass-factory employees.

    According to the 2017 WHO classification (4th version), PanNEC G3 was subdivided into two groups:well-differentiated PanNET G3 and poorly differentiated PanNEC. Considering the insufficient number of case reports, appropriate chemotherapy for the new category PanNET G3 remains unknown. Here, we report a case of PanNET G3 that responded to platinum-based chemotherapy.
