Objective This longitudinal study aimed to clarify the changes in the medical treatment behavior of Japanese patients with chronic diseases during the early phase of the coronavirus disease 2019 (COVID-19) pandemic and examine the factors associated with disease worsening. Methods Subjects with chronic diseases were selected from a panel survey that started at the beginning of the COVID-19 pandemic consists of 2,400 participants recruited via the Internet. Medical treatment behaviors (decrease in medical visit frequency, inability to take regular medications, and utilization of telephone/online medical care), psychological distress, and sociodemographic factors were evaluated at baseline (May 2020) and at the follow-up survey (February 2021). ⋯ Conclusions A decreased frequency of medical visits was observed among one-third of the participants with chronic disease in the early stage of the pandemic, and it reduced by half at follow-up. In the early stages of an emerging infectious disease pandemic, decreased regular hospital/clinic visits can lead to a worsening of chronic diseases. Those who had psychological distress, unemployment, and a history of smoking were vulnerable to a worsening chronic disease.

Renal Medullary Angiitis Associated with Cutaneous Leukocytoclastic Vasculitis: A Case Report.
Renal medullary angiitis is characterized by interstitial hemorrhaging in the medulla with neutrophil infiltration. An 81-year-old man presented with a fever, kidney dysfunction, and purpura of the legs, which was diagnosed as leukocytoclastic vasculitis. ⋯ An immunofluorescence analysis was negative, and electron microscopy revealed no immune-dense deposits, ruling out immunoglobulin A vasculitis. Intravenous methylprednisolone for three days and plasma exchange followed by oral prednisolone improved his general condition.

A 71-year-old woman was treated with osimertinib for stage IV adenocarcinoma with epidermal growth factor receptor (EGFR) mutations. Treatment led to improvements in the primary tumor, multiple lung metastases, and multiple bone metastases. ⋯ However, blood tests were positive for hepatitis B surface antigen and hepatitis B virus DNA, suggesting hepatitis B virus reactivation. The patient died of liver failure despite treatment with steroids and antiviral drugs.

A 57-year-old woman with a liver injury was referred to our hospital. She had a history of heavy alcohol consumption and had developed severe alcoholic hepatitis. ⋯ The patient was treated with short-term steroid therapy for liver injury and vancomycin administration for B. cereus sepsis, which led to recovery. The findings in the present case suggest the need for empirical therapy with vancomycin in patients with severe alcoholic hepatitis and suspected B. cereus infection.

Although the frequency of community-acquired infections caused by Klebsiella pneumoniae subsp. ozaenae (K. ozaenae) is low, they are often detected in sputum specimens. In addition, lung abscesses, necrotizing pneumonia, and urinary tract infections caused by K. ozaenae have also been reported. ⋯ Cases of K. ozaenae meningitis complicated by diabetes mellitus and sinusitis have been reported elsewhere. When Klebsiella pneumoniae is detected in such cases, it is important to use other detection methods in addition to mass spectrometry for correct identification.
