Case Reports
Asystole-induced Bradycardia by Dexmedetomidine during Endoscopic Submucosal Dissection.
Although dexmedetomidine (DEX) is a widely used analgesic and sedative agent for endoscopic procedures, cardiovascular complications, such as bradycardia and hypotension, are frequently experienced. We herein report the first case of asystole-induced bradycardia due to DEX during endoscopic submucosal dissection (ESD). ⋯ The patient's heart rate gradually decreased, and then cardiac arrest occurred. DEX has a risk of cardiac arrest, so bradycardia should not be underestimated during sedation with DEX.

Autosomal recessive spinocerebellar ataxia of type 10 (SCAR10) is a very rare neurodegenerative disease caused by mutations in the TMEM16K (ANO10) gene. This disorder is characterized by slowly progressive cerebellar ataxia and pyramidal signs inconstantly associated with cognitive decline, polyneuropathy, epilepsy, and vesicorectal dysfunction. To date, more than 40 cases have been reported in Europe. ⋯ We herein report the third Japanese case of SCAR10 harboring a novel homozygous deletion mutation (c.616delG, p. Glu206Lysfs*17). This case presented with adult-onset slowly progressive spastic ataxia with cerebellar atrophy and mild cognitive decline.

The case of a 28-year-old man who had primary sclerosing cholangitis and autoimmune hepatitis overlapping syndrome (PSC-AIH OS) complicated by ulcerative colitis (UC) is reported. First, he was diagnosed with PSC complicated by UC and initially treated with ursodeoxycholic acid and mesalazine. ⋯ If liver damage worsens in PSC patients, PSC-AIH OS should be considered. The optimum management approach for PSC-AIH OS should be established.

Case Reports
Multisystem Inflammatory Syndrome in Adults Accompanied with Kikuchi-Fujimoto Disease: A Case Report.
We herein report a case of multisystem inflammatory syndrome in adults (MIS-A) complicated with Kikuchi-Fujimoto disease (KFD). A previously healthy 41-year-old man presented with painful swelling of the cervical lymph nodes, fever, diarrhea, conjunctivitis, edema, and hypotension one month after the onset of asymptomatic coronavirus disease 2019. Laboratory investigations revealed an elevation of CRP, and echocardiography indicated diastolic dysfunction. ⋯ Histopathology of the lymph nodes showed necrotizing lymphadenitis. After the initiation of hydrocortisone and diuretics, his symptoms resolved immediately. This case suggested that post-viral immune dysregulation in MIS-A could play a role in the etiology of KFD.

A 49-year-old woman presented with nephrotic-range proteinuria, microhematuria, and moderate renal dysfunction. Diuretic-resistant refractory ascites associated with nephrotic syndrome were observed. ⋯ Cell-free and concentrated ascites reinfusion therapy (CART) performed to treat the refractory ascites improved the ascites and anasarca. Rituximab successfully treated the PGNMID, while CART effectively treated the refractory ascites associated with nephrotic syndrome.
