Hemolytic Anemia after Acute Hepatitis B Virus Infection: A Case Report and Systematic Review.
Hemolytic anemia and pure red cell aplasia are rare hematological complications of hepatitis B virus infection. We herein report a 24-year-old man who was diagnosed with hemolytic anemia and possible transient pure red cell anemia eight weeks after a severe episode of acute hepatitis B virus infection. ⋯ Hemoglobin returned to baseline within three months. As the clinical features of hemolytic anemia associated with hepatitis B virus have not yet been elucidated, we conducted a systematic review and present an analysis of the 20 reported cases, including our present case.

COVID-19 vaccine-related myocarditis has been reported worldwide. We herein report two Japanese cases with suspected vaccine-related myocarditis. A 27-year-old man was admitted with chest pain 4 days after the second vaccination. ⋯ In both cases, cardiac magnetic resonance imaging findings were consistent with myocarditis. They recovered with symptomatic relief within a few days. These cases suggest that the benefit of COVID-19 vaccination exceeds the risk of vaccine-related myocarditis.

An 84-year-old woman visited our hospital for dyspnea due to right pleural effusion, with lymphocytic dominance and a high adenosine deaminase (ADA) level, that had been noted 1 month earlier. She was suspected of having tuberculosis pleurisy; however, anti-tuberculosis treatment yielded no improvements. ⋯ Her symptoms improved after starting steroid therapy. Cases of pleural effusion due to SjS with a high ADA level may be misdiagnosed as tuberculosis pleurisy.

Listeria monocytogenes can cause gastrointestinal infections in healthy children and adults, but they tend to be mild and self-limiting. It can, however, cause serious potentially lethal infections, such as meningitis and bacteremia, to those with underlying conditions. A woman in her 60s with liver cirrhosis developed abdominal pain and a fever, and she turned out to have a perianal abscess caused by L. monocytogenes. Perianal abscess is a rare complication of L. monocytogenes, but a recent epidemiological study revealed that the presence of cirrhosis might also be a risk factor for the development of invasive disease.
