A case of choroidal metastasis from renal cell carcinoma significantly reduced by radiotherapy.

Introduction: Choroidal metastasis from renal cell carcinoma is relatively rare and unresponsive to systemic treatment.

Case Presentation: A man in his eighties with left renal cell carcinoma and pulmonary metastasis developed visual impairment in the left eye during primary treatment with ipilimumab and nivolumab followed by secondary treatment with cabozantinib. Consultation with an ophthalmologist revealed choroidal metastasis, which was subsequently treated with local radiotherapy (3 Gy × 10 Fr), resulting in a significant reduction in the metastatic lesions.

Evaluation of a new oil adjuvant for use in peptide-based cancer vaccination.

Vaccine therapies are increasingly being used for the treatment of various diseases, and the antigen molecules themselves are being expanded from whole microorganisms to fine molecules such as peptides. Accordingly, there is a need for new adjuvants to support these new applications. In this paper, we used pharmaceutical grade mineral oil and sorbitan monooleate to develop a new oil adjuvant formula, NH(2) , and investigated its effects on peptide vaccination at both the pre-clinical and clinical levels.

Necrotizing fasciitis caused by Haemophilus influenzae type b in an elderly patient.

Necrotizing fasciitis caused by Haemophilus influenzae type b is a rare infection of the skin and soft tissues. The only previously reported case involved a healthy infant. We report herein the case of an 81-year-old Japanese woman with diabetes mellitus who developed necrotizing fasciitis caused by H.
