Seventeen patients (12 with native and five with prosthetic tricuspid valves) with tricuspid stenosis were studied by Doppler echocardiography followed by cardiac catheterization within 24 h. The mean tricuspid diastolic pressure gradient was calculated using the modified Bernoulli equation. Tricuspid valve area (TVA) was calculated by the pressure(More)
INTRODUCTION Hydroxychloroquine (HCQ) is a common disease modifying therapy for the treatment of rheumatoid arthritis (RA). Prior research suggests that HCQ may reduce the risk of diabetes mellitus in patients with RA. To investigate the mechanism of this effect, we examined the effect of HCQ on insulin resistance, insulin sensitivity, and pancreatic β-cell(More)
OBJECTIVE Observational studies suggest that hydroxychloroquine (HCQ) may reduce the risk of developing diabetes mellitus in patients with rheumatoid arthritis (RA). We examined the effect of HCQ on insulin resistance in subjects without diabetes mellitus with stable RA. METHODS Twenty-three RA subjects not currently using HCQ completed a 16-week,(More)
Two patients with seriously impaired left ventricular function, abnormal left ventricular conduction on the electrocardiogram, mitral regurgitation, and a very late systolic click are reported. Idiopathic non-obstructive cardiomyopathy seemed to be the cause of the left ventricular dysfunction in both cases. The mitral valve was anatomically normal at the(More)
Brucella endocarditis is an underdiagnosed, fatal complication of human brucellosis. Four successfully treated cases of Brucella endocarditis are reported. The development of a new valvar lesion and bulky vegetations seen on echocardiography helped to identify Brucella endocarditis occurring during systemic brucellosis. The aortic valve was affected in all(More)
