ABSTRACT

BACKGROUND: Coronavirus disease 2019 (COVID-19)-associated cytotoxic lesions of the corpus callosum (CLOCCs) have been reported as a rare neurological abnormality in severe cases. Here, a case of CLOCCs in the early stages of mild COVID-19 infection during the Omicron BA.1 epidemic is reported, along with a literature review. CASE REPORT: A Japanese woman with COVID-19 presented to the emergency department with altered consciousness and cerebellar symptoms a day after fever onset. Magnetic resonance imaging (MRI) revealed a lesion with restricted diffusion in the corpus callosum. She exhibited no complications of pneumonia, her neurological symptoms resolved after two days, and following MRI after 10 days, the brain lesion was absent. LITERATURE REVIEW: We searched the PubMed database for case reports that met the definition of CLOCCs proposed by Starkey et al. Fifteen COVID-19-associated cases were reported as CLOCCs, and 13 others were described under former terms, including mild encephalitis/encephalopathy with a reversible splenial lesion. All 15 adult cases with a documented course were accompanied by pneumonia or hypoxemia, while pediatric cases mostly had a multisystem inflammatory syndrome. CONCLUSION: COVID-19-associated CLOCCs can occur, even at an early, nonsevere stage. Therefore, this condition may be underdiagnosed if MRI is not performed.

ABSTRACT

This study focuses on high school athletics. The Japan High School Athletic Federation, which is the central sports organization of the high school athletics competition, and the National High School Athletic Federation, which is the governing body of the high school sports organization, manage the high school athletics category under the umbrella of the National High School Athletic Federation. This paper aimed to analyze the kind of relationship being built with the National Athletics Department, which is responsible for the actual management of the tournament, and to verify whether there is a conflict between the National Athletics Department and the National Athletics Department. Specifically, we analyzed the actual functions of the National High School Championships, the Japan Association of Athletics Federations, and the National High School Championships, and the level of support each organization had at the Inter-High School Championships held during the coronavirus pandemic. Then, based on the articles of incorporation and regulations of each organization, we organized the objectives, business contents, and decision-making of the three organizational operations, and observed conflicts. We found that the National High School Federation and the National High School Federation Land Specialization Department have four local conditions of conflict : "ambiguity of work in charge", "reciprocity of tasks", "common resources", and "mismatch of social evaluation".

ABSTRACT

Postpartum thyroiditis (PPT) is characterized by mild thyrotoxicosis occurring within one year of parturition commonly followed by transient hypothyroidism. Having genetic background of autoimmune thyroid disorders is a risk factor for it because the immune reactivation during postpartum period is a trigger for PPT. Pandemic of COVID-19: caused by SARS-CoV-2 infection is a global health problem, and occurrence of Graves? disease and Hashimoto?s thyroiditis after the viral infection have been reported but occurrence of PPT with COVID-19 has never been reported. A 29-year-old woman developed general fatigue four and a half months after parturition, and was diagnosed as having PPT: one month before, she had COVID-19. Hereafter, we define the date of delivery as Day 0 to make timeline clear. SARS-CoV-2 infection was diagnosed by PCR on Day 103, its disappearance from the upper airway confirmed on Day 124, and the thyroiditis diagnosed on Day 136. She had been euthyroid on Day 0 and 95, but thyrotoxic on Day 136. Serum thyroglobulin (Tg) concentration was normal in the presence of anti-Tg antibody, other thyroid-related autoantibodies were negative, and by ultrasonography, the thyroid gland was normal in size and no evidence of increased vascularity. Thyroid function returned to normal by Day 172 without any specific drug therapy. In conclusion, although a clear causal relationship could not be found, we documented the world?s first case of PPT developed following COVID-19.
