Objective The Mini-Z 2.0 is a new, simple, and nonproprietary tool for assessing physician well-being and burnout. To date, a non-English version of the Mini-Z 2.0 survey has not been validated. Therefore, we aimed to develop a Japanese version of the Mini-Z 2.0 and to evaluate its validity and reliability using survey data from physicians affiliated with an internal medicine academic society. ⋯ Cronbach's alpha for the sample was 0.80. Conclusion The Japanese version of the Mini-Z 2.0 demonstrated good internal consistency and convergent validity. Despite its inadequate structural validity, it can be used to measure physician well-being and related workplace conditions in Japan.

We herein report the case of a 54-year-old Japanese man with hepatitis C virus (HCV)-related membranoproliferative glomerulonephritis (MPGN), which developed at the time of relapse of immune thrombocytopenic purpura (ITP) after rituximab therapy. Antiviral therapy for HCV led to the improvement of both MPGN and ITP. Rituximab therapy may have contributed to the exacerbation of HCV infection and induced the development of HCV-related MPGN and the relapse of ITP. Our case suggested that HCV treatment should be prioritized over rituximab therapy for HCV-positive patients with ITP and that antiviral therapy for HCV may be effective for treating ITP itself.

Case Reports
Age-related Epstein-Barr Virus-associated Lymphoproliferative Disorder Masquerading as Systemic Lupus Erythematosus.
Age-related Epstein-Barr virus (EBV)-positive B-cell lymphoproliferative disorder (LPD) occurs in elderly patients without immunodeficiency. An 81-year-old woman without any known immunodeficiency was examined for fever, rash, arthritis, thrombocytopenia, pleural and pericardial effusions, lymphadenopathy, and positive autoantibodies, which satisfied the classification criteria for systemic lupus erythematosus (SLE). ⋯ In young individuals, EBV infection is a major differential diagnosis of SLE, but to our knowledge, this is the first reported case of age-related EBV-LPD mimicking SLE. We should therefore consider EBV-related disorders in the differential diagnosis of SLE even in elderly individuals.
