Quantifying the Reversibility of Clofazimine-induced Pigmentation in a Patient with Mycobacterium abscessus Pulmonary Disease.

A 45-year-old woman with Mycobacterium abscessus pulmonary disease was treated with multidrug therapy, including clofazimine, at Fukujuji Hospital. Six months after clofazimine initiation, the treatment was discontinued at the patient's request due to hyperpigmentation. Pigmentation is a critical side effect of clofazimine.

Validation of a diagnostic flowchart for tuberculous pleurisy in pleural fluid with high levels of adenosine deaminase.

Introduction: Adenosine deaminase (ADA) in pleural fluid is a useful marker for diagnosing tuberculous pleurisy. However, recent studies have reported a lower specificity of pleural fluid ADA levels. We previously developed a diagnostic flowchart for patients with pleural fluid ADA ≥40 U/L, incorporating variables such as pleural fluid lactate dehydrogenase <825 U/L, predominant pleural fluid neutrophils or cell degeneration, and a pleural fluid ADA/total protein ratio <14.

Two-Year Outcomes of Primary Prophylactic Use of Defibrillators for Ischemic and Non-Ischemic Cardiomyopathy - Propensity Score-Matched Analysis From the Nippon Storm Study.

Background: In 2016, the DANISH study reported negative results regarding the efficacy of implantable cardioverter-defibrillators (ICDs) in patients with non-ischemic cardiomyopathy (NICM) and reduced left ventricular ejection fraction (LVEF). In this study we determined the efficacy of using ICDs for primary prophylaxis in patients with NICM.

Methods and results: We selected 1,274 patients with underlying cardiac disease who were enrolled in the Nippon Storm Study.
