One hundred consecutive patients admitted to the Port Sudan Hospital with a temperature greater than or equal to 100 degrees F were evaluated. Enteric fever was diagnosed in 19 patients and malaria in 13. Virologic studies identified 21 cases of dengue infection. One dengue 1 and 17 dengue 2 infections were diagnosed by viral isolation. Three untyped dengue(More)
OBJECTIVES To document the duration of fetal cardiac time intervals in uncomplicated singleton pregnancies using a novel non-invasive fetal electrocardiography (fECG) system and to demonstrate this technique's ability to acquire recordings in twin and triplet pregnancies. DESIGN Prospective cross sectional observational study. SETTING Antenatal wards(More)
BACKGROUND Despite successful repair of coarctation of the aorta in childhood, adult survivors often have hypertension at rest or on exercise, and their life expectancy is shorter than normal because of premature coronary and cerebrovascular disease. This may be related to persistent structural and functional arterial abnormalities after surgery. METHODS(More)
OBJECTIVE To test the hypothesis that identical twins show no inter-twin differences in cardiovascular structure or physiology in fetal life unless there has been twin-twin transfusion syndrome. DESIGN Unselected prospective case-control observational study of fetoplacental haemodynamics including echocardiography at a median of 24 (16.7 to 32.3) weeks,(More)
UNLABELLED Current echocardiographic assessment of fetal ventricular function uses relatively crude measures and this has led to inconsistencies in assessment of diastolic function. Long axis parameters may be more insightful. OBJECTIVE To describe fetal long axis cardiac function and construct reference ranges. DESIGN 159 normal fetuses were studied(More)
OBJECTIVES Isolated fetal coarctation of the aorta (CoA) has high false-positive diagnostic rates by cardiologists in tertiary centers. Isthmal diameter Z-scores (I), ratio of isthmus to duct diameters (I:D), and visualization of CoA shelf (Shelf) and isthmal flow disturbance (Flow) distinguish hypoplastic from normal aortic arches in retrospective studies,(More)
Considerable advances in ultrasound technology and close collaboration between the specialties of paediatric cardiology and fetal medicine have resulted in the increasing ability to diagnose congenital heart disease before birth over the last two decades. Fetal cardiology diVers from paediatric cardiology not only in the spectrum of diseases seen, but also(More)
Progressive stenosis of the semilunar valves in utero can be life threatening. We treated two fetuses with complete or almost complete pulmonary atresia and imminent hydrops (increased cardiothoracic ratio, pericardial effusion, holosystolic tricuspid regurgitation extending into diastole, and abnormal venous Dopplers). We dilated the pulmonary valve of two(More)
