ABSTRACT

A 72-year-old woman with hypertrophic cardiomyopathy was admitted to the hospital after an appropriate implantable cardioverter-defibrillator shock for ventricular fibrillation. She was discharged after the addition of amiodarone. Eight months after discharge, she was admitted to the hospital with a sign of somnolence. She had low levels of serum sodium and plasma osmolality, as well as hepatic transaminitis. She underwent a computed tomography scan, which detected high liver density. Amiodarone-induced syndrome of inappropriate antidiuresis with hepatic transaminitis was diagnosed, and amiodarone was discontinued. After discharge, her hepatic transaminitis improved, and there was no recurrence of hyponatremia with a sign of somnolence. Amiodarone is an important drug used to treat ventricular arrhythmias. However, it has a variety of adverse effects. Syndrome of inappropriate antidiuresis is a rare complication of amiodarone. If hyponatremia occurs after starting amiodarone, this complication should be considered. Learning objective: Amiodarone is an important drug used to treat ventricular arrhythmias, such as ventricular tachycardia and ventricular fibrillation. However, amiodarone has a variety of adverse effects. Syndrome of inappropriate antidiuresis is a rare complication of amiodarone. If hyponatremia occurs after starting amiodarone, this complication should be considered.

ABSTRACT

Behçet's disease is an inflammatory disease which manifests itself as various symptoms, such as uveitis, oral and genital aphthae, erythema nodosa, gastro-intestinal ulcerations and encephalopathy. Among the manifestations, renal dysfunction is reported in some percentage of the patients with this disorder. We experienced a middle-aged male with Behçet's disease who showed an extremely high level of urinary ß2-microglulin, which is one of the markers of renal dysfunction, despite normal serum creatinine levels. The patient was on non-steroidal anti-inflammatory drug (NSAID) therapy for 7 weeks, and this could have affected his renal dysfunction. The present report suggests that renal injury should not be underestimated in patients with Behçet's disease, especially in patients using NSAIDs.

ABSTRACT

BACKGROUND: Non-pharmacological options for symptomatic management of cough are desired. Although chest wall mechanical vibration is known to ameliorate cough reflex sensitivity, the effect of mechanical vibrations on perceptions of urge-to-cough has not been studied. Therefore, we investigated the effect of mechanical vibration of cervical trachea, chest wall and femoral muscle on cough reflex sensitivity, perceptions of urge-to-cough as well as dyspnea. METHODS: Twenty-four healthy male never-smokers were investigated for cough reflex sensitivity, perceptions of the urge-to-cough and dyspnea with or without mechanical vibration. Cough reflex sensitivity and urge-to-cough were evaluated by the inhalation of citric acid. The perception of dyspnea was evaluated by Borg scores during applications of external inspiratory resistive loads. Mechanical vibration was applied by placing a vibrating tuning fork on the skin surface of cervical trachea, chest wall and femoral muscle. RESULTS: Cervical trachea vibration significantly increased cough reflex threshold, as expressed by the lowest concentration of citric acid that elicited five or more coughs (C5), and urge-to-cough threshold, as expressed by the lowest concentration of citric acid that elicited urge-to-cough (Cu), but did not significantly affect dypnea sensation during inspiratory resistive loading. On the other hand, the chest wall vibration not only significantly increased C5 and Cu but also significantly ameliorated the load-response curve of dyspnea sensation. CONCLUSIONS: Both cervical and trachea vibrations significantly inhibited cough reflex sensitivity and perception of urge-to-cough. These vibration techniques might be options for symptomatic cough management.
