Abstract

Background: It was hypothesized that the use of Pentoxifylline would increase arterial O2 saturation and increase exercise tolerance in patients with Chronic Obstructive Pulmonary Disease (COPD). Methods: We tested this hypothesis in 23 patients with COPD and pulmonary hypertension. Patients were randomized to receive Pentoxifylline or placebo, each for a 12-week period, in a prospective, double-blind study to assess the effects of Pentoxifylline on oxygen saturation and exercise tolerance via pulse oximetry and the 6-Minute Walk Test (6MWT). Results: At the end of the 12 weeks, the six-minute walk distance rose from 351.9±65 meters to 393±67 meters in the Pentoxifylline group (10 patients) and increased from 328±79 meters to 353±66 meters in the placebo group (10 patients) (P=0.142). Resting oxygen saturation by pulse oximetry changed from 87±4% to 85±14% in the Pentoxifylline group and from 88±3% to 88±2% in the placebo group (P=0.676). There were no significant changes in dyspnea severity index and heart rate before and after the 6MWT. Conclusion: Pentoxifylline does not seem to improve exercise capacity and dyspnea in patients with severe and very severe COPD. Trial Registration Number: IRCT201202018889N1

Abstract

The aim of this study was to determine the left ventricular myocardial deformation and segmental myocardial dysfunction by speckle tracking echocardiography and tissue Doppler imaging among the operated patients with anomalous origin of the left coronary artery from the pulmonary artery. The study was conducted on 12 patients diagnosed with anomalous origin of the left coronary artery from the pulmonary artery, who had been operated upon between 2001 and 2013 at the medical centres of Shiraz University of Medical Sciences, Shiraz, Iran. The mean age of the patients at the time of surgical correction was 12.6 years ranging from 6 months to 43 years, and the duration of postoperative follow-up was between 1 and 12 years. Comparison of the strain rate between the patients with acceptable ejection fraction and the control group by tissue Doppler imaging showed significant differences between the two groups regarding the lateral wall (p

Abstract

The occurrence of Brucella endocarditis following Bentall operation is a rare and life threatening condition, particularly when it is complicated by development of a pseudoaneurysm. Here we present a 40-year-old veterinarian with bicuspid aortic valve, who developed type A aortic root dissection and required Bentall operation. His past medical history was positive for an episode of treated brucellosis. Four months after the operation, he developed signs, symptoms and serological findings of brucellosis for the second time and was treated with antibiotics. Then after he was well untill about 14 days prior to his recent admission, when he again developed hip pain, fever, shortness of breath, profound fatigue and weakness. His transthoracic echocardiography was suggestive of endocarditis. A transesophageal echocardiogram revealed detachment of valve-conduit from the annulus and the mitral-aortic intervalvular fibrosa and the presence of a large aortic pseudoaneurysm with multiple vegetations attached to its Dacron walls. A huge pseudoaneurysm was detected at surgery and the whole valve-conduit was replaced with a 25 mm homograft. Blood and vegetation cultures turned to be positive for Brucella melitensis. Early echocardiographic diagnosis and prompt surgical intervention were helpful for survival of our patient who had aortic pseudoaneurysm complicated by Brucella endocarditis.
