The aim of this study is to determine the oxidative state of term and preterm neonates at the moment of birth and during the first days of life, and the influence of exposure to oxygen on the premature neonates.A total of 20 neonates were selected. Group A: 10 healthy full-term neonates, and Group B: 10 preterm neonates with no other pathology associated,(More)
Between November 1972 and November 1986, 108 patients aged 5 to 73 years had complete replacement of the aortic root with an aortic homograft into which the coronary arteries were implanted. The main indications were (1) a tunnel type of aortic obstruction involving a hypoplastic ring, (2) a para-aortic annular abscess, (3) prosthetic valve dysfunction,(More)
Long-term results with 555 aortic homografts used for isolated aortic valve replacement (AVR) between 1964 and 1986 were analyzed to assess valve performance and the time-related onset of valve-related events. The total follow-up was 2,931 patient-years. Twenty years after operation, overall survival was 51.6 +/- 8.1%, freedom from valve-related death was(More)
Aortic valve replacement with a pulmonary autograft was performed on 241 patients between June 1967 and October 1986 at National Heart Hospital, Guy's Hospital, Middlesex Hospital, Harley Street Clinic, and Italian Hospital in London by one of the authors (D.N.R.). The longest follow-up is 18 years 7 months, and the cumulative total follow-up is 1130(More)
The management of three patients with left ventricular fibromas is outlined. All were asymptomatic children. Routine chest radiography suggested cardiac masses. M-mode and two-dimensional echocardiography were valuable adjuncts to conventional angiography in assessing these children. Electrocardiographic changes, present in all cases, were shown to regress(More)
OBJECTIVE To study the outcome of a modified oral desensitization protocol for trimethoprim-sulfamethoxazole in human immunodeficiency virus infected patients with Pneumocystis carinii pneumonia and acquired immune deficiency syndrome. DESIGN A prospective study. SETTING Tertiary care referral center. PATIENTS Thirteen human immunodeficiency virus(More)
AIM To evaluate the ocular surface symptoms and signs associated with preservative-free 0.0015% tafluprost in patients with glaucoma or ocular hypertension (OHT). METHODS Prospective non-interventional, multicentre, observational study on 134 patients, naive or on previous treatment with another prostaglandin analogue. In each visit (V1 baseline visit, V2(More)
This article reports the successful surgical treatment of six patients who presented with prosthetic endocarditis and uncontrolled bacteremia. They were treated by replacement of the aortic root with a preserved homograft aortic valve. With this technique, ventricular-aortic continuity was established with a centrally flowing valve together with its(More)
Aortic valve replacement (AVR) with a pulmonary valve autograft (PVA) was first reported by Donald N. Ross (DNR) in 1967. The expectation of this procedure was to avoid degenerative changes seen in other biological tissue valves such as calcification, attenuation, and rupture of the leaflets. Recent reports by the original investigator's group have(More)
Since 1983 percutaneous balloon dilatation of the right ventricular outflow tract has been performed as an alternative to surgical palliation in selected cases of tetralogy of Fallot at the Royal Liverpool Children's Hospital. From 31 December 1984 to 31 December 1988, 27 of these patients underwent subsequent surgical correction. Age at operation ranged(More)
