A 56-year-old woman was referred to our hospital for the further evaluation of drug-refractory heart failure with a reduced ejection fraction. A family history interview revealed that men in her family had died of Duchenne muscular dystrophy (DMD), whereas she had no skeletal muscle disorder. ⋯ X-linked dilated cardiomyopathy (XLDCM). In conclusion, careful family history interviews and an investigation of dystrophinopathy are required to detect XLDCM in women.

A 34-year-old pregnant woman in the 34th week of gestation with uncontrolled asthma was admitted because of asthma exacerbation. Although she received bronchodilators and systemic corticosteroids, respiratory failure rapidly progressed. Chest computed tomography revealed a mass occluding approximately 80% of the tracheal lumen. ⋯ The pathological findings of the resected tumor were compatible with tracheal glomus tumor. Tracheal tumors are often misdiagnosed as asthma, but its complication with asthma is rare. Even if the diagnosis of asthma is definitive, clinicians should consider coexisting diseases, including tracheal tumors, when asthma control is poor.

Case Reports
Two Cases with Isolated Splenic Sarcoidosis Diagnosed by an Ultrasound-guided Fine-needle Aspiration Biopsy.
Asymptomatic splenic nodules were detected incidentally in two middle-aged women at an annual checkup. They showed no abnormalities on laboratory tests, but imaging studies revealed splenic nodules. No other localized lesions were found. ⋯ We performed US-guided percutaneous aspiration biopsies using 21-gauge needles without complications, including bleeding. Pathological specimens showed noncaseating granulomas, so both patients were diagnosed with isolated splenic sarcoidosis. A US-guided fine-needle aspiration biopsy is a safe and useful method for diagnosing splenic nodules.

Case Reports
A Case of Invasive Mucinous Adenocarcinoma with Acute Respiratory Distress Syndrome Diagnosed by Autopsy Findings.
We herein report a fatal case of invasive mucinous adenocarcinoma (IMA) with acute respiratory distress syndrome (ARDS) diagnosed based on autopsy findings. A 76-year-old man presented with severe respiratory discomfort on admission. ⋯ A bronchoscopic lung biopsy had shown organizing pneumonia, but a post-mortem examination surprisingly revealed IMA with organizing pneumonia. IMA presenting with ARDS as the first symptom is extremely rare.

Objective This study explored the predictors of hydroxychloroquine intolerance and propose appropriate methods to initiate hydroxychloroquine in patients with systemic lupus erythematosus. Methods This retrospective study registered consecutive patients who were diagnosed with systemic lupus erythematosus and started treatment with hydroxychloroquine between 2015 and 2021. Any adverse events that required dose reduction or cessation of hydroxychloroquine, indicating intolerance to the drug, were recorded for up to 26 weeks after initiation of hydroxychloroquine. ⋯ Multivariable analyses revealed that the hydroxychloroquine dose per ideal body weight and higher levels of C4 predicted hydroxychloroquine intolerance. In particular, C4 levels were positively correlated with cutaneous reactions, whereas the dose of prednisolone was negatively correlated with gastrointestinal reactions. Conclusion Low-dose hydroxychloroquine may be optimal for induction in patients with systemic lupus erythematosus who have high C4 levels or are taking low doses of steroids.
