Background Homeless persons are those who carry out their activities of daily living in city parks and other facilities. Little is known about homeless patients with lung cancer in Japan. Therefore, we characterized the clinical features and outcomes of homeless people in metropolitan Tokyo. ⋯ During the study, nine patients died in the hospital, and four were lost to follow up. Conclusion It is difficult for homeless patients to continue chemotherapy, and they often quit therapy willfully. Therefore, it is necessary to develop an education and health insurance support system to ensure treatment continuity in a good social environment.

Accurate genotyping is important to improve the treatment of hepatitis C virus (HCV) infection. We herein report a 44-year-old Japanese man with hemophilia A and coinfection of HCV and human immunodeficiency virus (HIV) who was diagnosed with HCV genotype 4 by direct sequencing. ⋯ Although several HCV genotyping tests are available in Japan, it is important to recognize that some cannot detect genotype 4. Care should be taken when genotyping HCV patients who have received non-heated coagulation factor preparations or were infected abroad.

A 56-year-old woman presented with dermatomyositis positive for anti-melanoma differentiation-associated gene 5 antibody. No interstitial lung disease was detected. Despite treatment with methylprednisolone pulse therapy and cyclosporine, dysphagia developed. ⋯ Disturbed consciousness developed shortly after TMA onset, and brain magnetic resonance imaging revealed hyperintensity lesions in the bilateral basal ganglia, thalami, and brainstem. The patient was diagnosed with atypical posterior leukoencephalopathy syndrome before dying of heart failure later that day. In conclusion, early TMA recognition and prompt intensive treatment are critical in such cases.

Chemotherapy for multiple primary malignancies is challenging. We herein report a case of synchronous primary lung adenocarcinoma and hepatocellular carcinoma (HCC). A 72-year-old man was admitted for the evaluation of an abnormal shadow on his lung. ⋯ He was diagnosed with synchronous primary lung adenocarcinoma and HCC. Atezolizumab, bevacizumab, carboplatin, and paclitaxel (ABCP) chemotherapy was efficacious for both tumors. ABCP chemotherapy may be a potential treatment option for synchronous primary lung adenocarcinoma and HCC.

Objective Although multiple nontuberculous mycobacteria (NTM) species can be isolated from the same patient, little has been reported on co-isolation. We clarified the trends and characteristics of the co-isolation of multiple NTM species. Methods To collect data on multiple NTM isolation, we first extracted all patients who visited our hospital from 2006 through 2015 with a diagnosis of NTM lung diseases other than Mycobacterium avium complex (MAC) and then reviewed their medical records to evaluate the co-isolation of multiple NTM species. ⋯ Among M. szulgai, M. peregrinum and M. terrae isolation, no other NTM species were detected. Conclusion Co-isolation of multiple NTM species was not uncommon, with 26% of patients with non-MAC NTM lung diseases showing co-isolation with multiple NTM species. Each NTM species had distinct characteristics in terms of co-isolation.
