Case Reports
A Case of Anti-SOX1 Antibody-positive Small-cell Lung Cancer that Triggered Opsoclonus.
A 72-year-old woman with opsoclonus visited our hospital and was diagnosed with small-cell lung cancer. Blood tests revealed anti-SOX1 antibodies, so the patient was diagnosed with paraneoplastic opsoclonus-myoclonus syndrome. ⋯ Anti-Ri and anti-Hu antibodies have been reported as autoantibodies associated with neoplastic opsoclonus-myoclonus syndrome; however, there are no such reports concerning anti-SOX1 antibody. Therefore, this is a valuable case.

We herein report a 45-year-old man with dentatorubropallidoluysian atrophy (DRPLA) who presented with mild dementia, ataxia, and involuntary movement and developed constipation, dysuria, and orthostatic hypotension. Thermography revealed an abnormal thermal response of the skin to cold stimulation. ⋯ The thermography results suggested the possibility of autonomic dysfunction. Although little is known regarding autonomic dysfunction in DRPLA, this report demonstrates the importance of autonomic dysfunction in DRPLA.

Objective The coronavirus disease 2019 (COVID-19) pandemic has led to a global restriction of public behavior due to lockdowns in various major cities. Lifestyle changes and reduced rates of outpatient lifestyle guidance/consulting may have had some impact on glycemic control in patients with type 2 diabetes. This study analyzed the impact of changes in the frequency of nutritional guidance/consulting (NGC) during the COVID-19 pandemic on outpatient care for type 2 diabetes. ⋯ Results The number of diabetes medications after the declaration of the COVID-19 emergency did not markedly increase in the CG (2.0±1.4 to 2.1±1.5, p>0.05) but significantly increased from 2.2±1.4 to 2.6±1.4 in the DG (p<0.005) and from 2.2±1.4 to 2.4±1.4 in the IGG (p<0.005). The increase in HbA1c adjusted for confounders was unchanged at 0.12±1.06% for the CG and -0.07±1.29% for the IGG but was significantly increased at 0.19±1.49% for the DG (p<0.05). Conclusion In patients with type 2 diabetes mellitus, regular nutritional guidance may be important for maintaining good glycemic control, even during the COVID-19 pandemic.

Review Case Reports
Relapsing Anti-MOG Antibody-associated Disease Following COVID-19 Vaccination: A Rare Case Report and Review of the Literature.
Anti-myelin oligodendrocyte glycoprotein antibody-associated disease (MOGAD) is an autoimmune demyelinating disorder that mainly occurs post-infection or post-vaccination. MOGAD after inoculation with coronavirus disease 2019 (COVID-19) vaccines is rare, and we herein report a rare case of a patient with MOGAD after vaccination using the Pfizer-BioNTech COVID-19 vaccine (BNT162b2, Pfizer Japan, Tokyo). Our report highlights the fact that MOGAD following inoculation with COVID-19 vaccine may show clinical relapse during reduction of the oral steroid dose, and continuous treatments with immunological agents is needed to prevent disease recurrence.
