BACKGROUND Cone-beam computed tomography (CBCT) has been changing the way dental practitioners use imaging. The radiation dose to the patient and how to effectively reduce the dose is still not completely clear to most users of this technology. OBJECTIVE The objective of this study was to quantitate the change in radiation dose when using different CBCT(More)
Although the interventional pediatric cardiology began in the early 1950s, it was not until the mid-1980s that a full spectrum of transcatheter interventions in children could be undertaken including balloon atrial septostomy which has been in usage since 1966. Enormous developments have occurred even from the mid-1980s to date. In this review, current(More)
We have reviewed nine cases of biliobiliary fistula operated during 1983-85. Two of these patients also had a high hepatic duct stricture, an association not highlighted before. Eight of these patients had jaundice. A classical cholecystectomy in the presence of biliobiliary fistula entails grave risk to the integrity of the upper biliary tract.(More)
I read with interest the paper by Mitchell et al. [7] in a recent issue of Pediatric Cardiology. They described results of balloon angioplasty of the atrial septum in animal models (swine and newborn lambs) and human subjects. They concluded that the procedure can effectively produce interatrial communications in animal models and suggested that this(More)
Childhood pulmonary embolism (PE) is a rare but serious condition marked by hypoxemia, shock, right-sided heart failure, and significant risk for fatality. Recommended treatment options include surgical embolectomy, anticoagulation, and thrombolysis. This report describes the successful use of recombinant tissue plasminogen activator to treat PE associated(More)
Onion (Allium cepa), a very commonly used vegetable, ranks third in the world production of major vegetables. Apart from imparting a delicious taste and flavour due to its pungency in many culinary preparations, it serves several medicinal purposes also. Processing and preservation of onion by suitable means is a major thrust area since a long time. The(More)
Echocardiograms and angiograms of six infants with left ventricular hypoplasia were examined. Three observations were made: (1) A normal-sized aortic root echogram may be seen in infants with mitral atresia, intact ventricular septum and normally related great arteries. (2) A recognizable mitral valve echogram may be seen in mitral atresia. (3) The true(More)
I read with interest the paper by Nir and associates in a recent issue of Pediatric Cardiology [14] discussing spontaneous intrauterine closure of a ventricular septal defect (VSD) in a fetus/neonate with double-outlet right ventricle. We have long been interested in the problem of spontaneous closure of "physiologically advantageous" VSDs [16-22] and would(More)
I read with interest the paper by Lewis and Chabot [1] published in a recent issue of Pediatric Cardiology. The authors retrospectively compared actuarial survival of 27 children with dilated cardiomyopathy treated with angiotensin-converting enzyme (ACE) inhibitors with that of 54 patients managed with conventional anticongestive (digoxin and diuretics)(More)
