Duchenne muscular dystrophy (DMD) is associated with neuropsychiatric disorders, and patients often present with autism spectrum disorder (ASD). We herein report a case of DMD accompanied by ASD that was successfully treated with aripiprazole, an atypical antipsychotic that has been used for treating irritability in child and early adolescent patients with ASD. The patient was diagnosed as having DMD at 3 years of age. Although he developed severe psychotic symptoms including irritability, insomnia, hallucinations, and delusions at 17 years of age, all the symptoms were successfully treated with aripiprazole without any detectable side effects.

Case Reports
Retrobulbar Optic Neuritis Induced by Pembrolizumab in a Patient with Lung Adenocarcinoma.
Pembrolizumab is a monoclonal antibody with anti-tumor effects. Only a few reports have previously described retrobulbar optic neuritis induced by pembrolizumab. We herein report the case of a 63-year-old man with advanced lung adenocarcinoma who received cisplatin, pemetrexed, and pembrolizumab combination therapy for six months. ⋯ He was diagnosed with retrobulbar optic neuritis and pembrolizumab-induced renal failure. After receiving corticosteroid treatment, his renal function rapidly improved. The optic neuritis improved somewhat, but it was not adequately resolved.

Acquired hemophilia A (AHA) is a bleeding disorder caused by the acquired appearance of inhibitor for factor VIII. Approximately half of all patients with AHA have some type of underlying disease. ⋯ To our knowledge, this is the first report of AHA triggered by a bacterial infection; however, there may be similar cases that remain undiagnosed because this pathogen is difficult to identify. Clinicians should consider the possibility of H. cinaedi as a causative pathogen in patients presenting with a fever of unknown origin.

Objective The stress brought on by changes in social conditions due to COVID-19 is diverse. However, there have been no studies examining the relationship between the type of stress felt by an individual due to such changes in social conditions and the degree of change in HbA1c, prompting us to conduct this study. Methods We conducted a collaborative study at two diabetes clinics. ⋯ In addition, as a result of comparing the amount of change between the 2 groups, a significant decrease was observed in the unstressed group compared with the stressed group (p=0.032). There was no significant difference in body weight change between the two groups. Conclusion Stress that cannot be avoided by one's own will, such as school closures for children, may affect glycemic control.

We herein describe a Charcot-Marie-Tooth disease (CMT) family with a MFN2 mutation with atypical ocular manifestations. The proband, his mother, his third daughter, and his deceased maternal grandfather all had symptoms of CMT and a visual impairment (either cataracts or severe astigmatism). ⋯ This missense mutation in MFN2 co-segregated with CMT and the atypical ocular manifestations in this family. The findings of this study might help to expand the clinical phenotype of heterogeneous MFN2-related CMT.
