Cardiothoracic ratio (CTR), the ratio of cardiac diameter (CD) to thoracic diameter (TD), is a useful screening method to detect cardiomegaly, but is reliable only on posteroanterior chest radiography (chest PA). We performed this cross-sectional 3-phase study to establish reliable CTR from anteroposterior chest radiography (chest AP). First, CD(Chest PA)/CD(Chest AP) ratios were determined at ...

Sickle cell anaemia (SCA) is one of the commonest chronic hemolytic anaemias in the Sudan; it is a disease with high mortality and morbidity. This study was conducted aiming to observe the clinical pattern of cardiac abnormalities in children with sickle cell anaemia, and to assess the relationship between the cardiac abnormalities and the severity of the disease. The study was conducted in sic...

Interstitial pneumonia (IP) frequently occurs in patients with scrub typhus, but its clinical significance is not well known. This study was designed to evaluate interstitial pneumonia as a marker of severity of the disease for patients with scrub typhus. We investigated clinical parameters representing the severity of the disease, and the chest radiographic findings for 101 patients with scrub...

beneficial effects of diltiazem were followed by an associated subjective improvement over an 11-month period.’ In this report we describe a late-stage patient who sustained a significant improvement with nifedipine over a 6-month period. This improvement was associated with a significant change in hemodynamic data measured repeatedly. A white female patient (age 27 years) was admitted for eval...

OBJECTIVE The objective of the study was to characterize the clinical profiles of pediatric patients with acute myocarditis and dilated cardiomyopathy (DCM) before diagnosis. METHODS A retrospective cross-sectional study was conducted to identify patients with myocarditis and DCM who presented over a 10-year span at 2 tertiary care pediatric hospitals. Patients were identified based on the In...

The dog is considered the main domestic reservoir for Trypanosoma cruzi infection and a suitable experimental animal model to study the pathological changes during the course of Chagas disease (CD). Vaccine development is one of CD prevention methods to protect people at risk. Two plasmids containing genes encoding a trans-sialidase protein (TcSP) and an amastigote-specific glycoprotein (TcSSP4...

BACKGROUND South Africa's HIV mortality is primarily due to pulmonary disease. No evidence exists regarding the correlation between HIV-infected children and specific chest radiographic patterns and CD4 levels of immunity in HIV-infected adults. Objectives. We aimed to determine the prevalence of specific radiographic features in HIV-infected children initiating anti-retroviral therapy (ART) to...

Ann Saudi Med 28(1) January-February 2008 www.saudiannals.net 45 Aneurysm of the vein of Galen is a rare intracran nial vascular abnormality associated with sen vere hemodynamic and central nervous and/or system disturbance leading to intrauterine death and/or early neonatal death.1 It is associated with a wide range of abnormalities like cardiomegaly, ventriculomegaly, intrauterine growth rest...

The purpose of the present study was to evaluate whether or not preoperative clinical parameters could predict left ventricular reverse remodeling in dogs who underwent successful patent ductus arteriosus (PDA) closure. Thirty-nine client-owned dogs diagnosed as PDA with left ventricular dilation were used. Increased left ventricular internal dimension index and decreased fractional shortening ...

OBJECTIVE To establish the time of onset of dilated cardiomyopathy (DCM) by review of annual chest x rays, which are obligatory in Hungary. DESIGN A retrospective survey of chest x rays of a cohort of confirmed cases of DCM, to assess time of onset of cardiomegaly. Clinical course was compared by follow up over a mean of six years from the time of diagnosis. SUBJECTS 240 patients with DCM (...
