Coronavirus disease 2019 (COVID-19) is a novel infectious disease affecting the general population worldwide. A fever and cough are the common clinical presentations of COVID-19. ⋯ Based on the clinical observations, alveolar destruction was likely associated with hemoptysis and bulla formation. Therefore, we suggest the follow-up of COVID-19 patients whose clinical parameters indicate alveolar damage, even after their symptoms improve.

Case Reports
A Case of Anti-glomerular Basement Membrane Glomerulonephritis During the First Trimester of Pregnancy.
A 28-year-old woman was admitted during the eighth week of her pregnancy because her clinical course was consistent with rapid progressive glomerulonephritis (RPGN). Anti-glomerular basement membrane antibody (anti-GBM Ab) and myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA) were positive, and the anti-GBM Ab titer being extremely high. ⋯ She had human leukocyte antigen (HLA)-DRB1*1502:01, which differs from the DRB1*1501 associated with anti-GBM GN. When patients have particular symptoms, we should check the urine and serum creatinine to exclude RPGN, even in cases of pregnancy.

Objective Although a number of studies have shown that both short and long sleep durations were associated with the risk of metabolic disorders related to obesity, the underlying mechanism is still not fully understood. In this study, we analyzed the association of sleep duration with metabolic, anthropometric, and lifestyle factors in patients with type 2 diabetes. Methods The subjects were 279 patients with type 2 diabetes 63 (52-70) years old (median and interquartile range) with a body mass index of 25.0 (22.2-28.3) kg/m2 and HbA1c levels of 8.7% (7.6-10.3%). ⋯ The body fat ratio and skeletal muscle mass were correlated positively and negatively, respectively, with sleep duration. When the subjects were divided into three groups based on sleep duration, the intakes of total energy, carbohydrates, and fat tended to be high in those with <5.5 hours of sleep, and the percentage of patients who had habitual physical activities was lower in those with >7 hours of sleep. Conclusion The observation that sleep duration is distinctly associated with excessive eating and a sedentary lifestyle may provide a basis for effective lifestyle management of patients with type 2 diabetes.

A 46-year-old woman with uveitis was referred to our respiratory diseases department in July 2018. Her medical history included transient bilateral hilar mediastinal lymphadenopathy (BHL) and multiple pulmonary nodules in May 2013 during pegylated interferon-alpha and ribavirin treatment for chronic hepatitis C infection. ⋯ This seem to be the first report of Propionibacterium acnes-associated sarcoidosis possibly initially triggered by interferon-alpha therapy. Understanding the mechanisms underlying interferon-triggered P. acnes-associated sarcoidosis may clarify the sarcoidosis immunopathogenesis.

Objective This study was conducted to clarify the prevalence of short segment Barrett's esophagus (SSBE) using endoscopic observations with linked color imaging (LCI). In addition, the relationship between the presence of Barrett's epithelium (BE) and the status of H. pylori infection was investigated. Methods The study subjects were 3,353 individuals (2,186 men, 1,167 women; mean age 55.2±9.4 years old) whose status of H. pylori infection had been determined. ⋯ The degree of gastric mucosal atrophy was higher in cases with BE (p<0.001), although negativity for H. pylori infection and mild gastric mucosal atrophy were significant factors for the development of longer BE. Conclusion A high prevalence of SSBE was noted when LCI was used to determine the area of BE, as the distal end of the palisade vessels was easily visualized. Negativity for H. pylori infection and mild gastric mucosal atrophy were not correlated with SSBE prevalence.
