In the current presentation, primary pancreatic cancer with metastatic hepatic tumors was initially suspected. However, the possibility of previously resected colon cancer metastasizing to the pancreas also had to be considered. CT findings alone could not make this distinction. Therefore, endoscopic ultrasound-guided fine-needle aspiration was performed. Histopathological examination of the pancreatic tumor indicated adenocarcinoma, with features similar to those of the previously resected colon cancer. Immunohistochemical staining was negative for cytokeratin 7 but positive for cytokeratin 20, caudal-type homeobox 2, and special AT-rich sequence-binding protein 2. These findings indicated a pancreatic metastasis of colonic origin. In addition, a percutaneous ultrasound-guided biopsy of one of the hepatic tumors had histopathological findings that were similar to those of the pancreatic tumor. Hence, the patient was diagnosed with pancreatic and hepatic metastases from the previously resected colon cancer.

Histopathological examination revealed histologic features of membranoproliferative glomerulonephritis. He was diagnosed with C3G and Sjögren's syndrome based on proteinuria, the histopathological findings, high levels of antibodies against SS-A, and lymphocytic infiltration around the salivary glands.

At 3 months after treatment, urinary protein excretion was decreased and hematuria had disappeared, and improvement in hypocomplementemia and the levels of antibodies against SS-A were observed.

Our findings demonstrated that RATS segmentectomy was found to be as safe as conventional segmentectomy, with shorter operation times and hospital stays. No significant differences were observed in intraoperative blood loss and rates of surgical complications. However, prolonged postoperative air leaks are a potential concern. Among simple segmentectomy cases, RATS still showed shorter operation time and hospital stay. The longer experience of the surgeons in the RATS group may be a reason for the shorter operation time in this group. Additionally, the use of preoperative transbronchial marking with indocyanine green dye and barium, and intraoperative identification of intersegmental boundaries using intravenously administered indocyanine green dye may contribute to shorter operation time. Further studies are warranted to clarify the long-term oncological outcomes.","PeriodicalId":44831,"journal":{"name":"Fukushima Journal of Medical Science","volume":" ","pages":"153-162"},"PeriodicalIF":0.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13193948/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145534942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the UL50-deficient strain may be a candidate as a vaccine strain or viral vector. In this study, the UL50-deficient strain demonstrated reduced levels of replication in brain and neurovirulence compared to the wild strain in 4-week-old mice, but not in newborn mice. Furthermore, the expression level of cellular DUT in the mouse brain was not detectable in 4-week-old mice, but was detectable in newborn mice. In vitro experiments showed replication of the UL50-deficient strain was reduced due to the knockdown of cellular DUT. These results suggest that in actively dividing cells, such as the brain neurons of newborn mice, efficient cellular DUT expression helps with the sufficient replication of the UL50 mutant, resulting in the same level of neurovirulence as that in the wild type. However, in the brains of 4-week-old mice, DUT expression is insufficient, resulting in reduced neurovirulence of the UL50 mutant. These results suggest that when using the UL50 mutant strain as a vaccine or virus vector, it is necessary to pay attention to the timing of inoculation.","PeriodicalId":44831,"journal":{"name":"Fukushima Journal of Medical Science","volume":" ","pages":"131-140"},"PeriodicalIF":0.9,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13193943/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145402323","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

He was suspected to have Down syndrome due to his characteristic facial appearance at birth. G-band staining of the peripheral blood when TAM was diagnosed showed trisomy 21, tetrasomy 21, and trisomy 19. The blasts disappeared from the peripheral blood at 4 months of age.

The Risk Communication group proposed a national 15th anniversary campaign to revise and renew public perceptions of Fukushima in Japan and abroad.
