A 13-year-old boy with atrial septal defect and tricuspid valve abnormality was reported. He had crepitan ralles and signs of heart failure. He was treated with digital, diuretic and antimicrobial therapies. After clinical improvement he underwent surgery. The atrial septal defect was closed, and ringplasty was applied to the tricuspid valve. After the operation, he could not be extubated becau...

The objective of this study was to determine the prevalence of diabetic retinopathy in a primary care setting using digital retinal imaging technology and to quantify the degree of diabetic retinopathy using internationally accepted severity scales. Two hundred patients with type 2 diabetes were evaluated clinically followed by fundus photography. The prevalence of retinopathy and maculopathy w...

anatomy of the root canal system always effects endodontic treatment outcome. mandibular premolar teeth show extreme variations in root canal morphology. first premolars usually exhibit basic one root and one canal anatomy. the occurrence of three roots in mandibular first premolar has not been commonly reported in literature. this article reports a case of successful nonsurgical endodontic man...

background: recurrent abortion is a difficult medical problem happening in about 1-2% of fertile women. most spontaneous miscarriages which happen in the first and second trimesters are caused by chromosomal abnormalities. objective: the present study tries to find the rate of chromosomal abnormalities in couples with recurrent pregnancy loss. materials and methods: in total 165 couples were re...

A growing body of studies suggests that neurological and mental abnormalities foster conformity to norms of rationality that are widely endorsed in economics and psychology, whereas normality stands in the way of rationality thus defined. Here, we outline the main findings of these studies, discuss their implications for experimental design, and consider how 'sane' some benchmarks of rationalit...

‘Normal’ comes from the latin norma, a carpenter’s square, and in mediaeval times meant something at a right angle or perpendicular. A few centuries later it came to mean conforming to a standard and was used in physics to refer to the average of a set of variables. If the variable concerned, such as head size or IQ, is continuous and has a normal distribution, by convention the normal range ha...

We propose a new approach to the use of circumscription for representing knowledge. Nested abnormality theories are similar to simple abnormality theories introduced by McCarthy, except that their axioms may have a nested structure , with each level corresponding to another application of the circumscription operator. The new style of applying circumscription sometimes leads to more economical ...

From 1 January 1985 to 31 December 1990, the Northern Region Fetal Abnormality Survey received 736 notifications of fetuses with suspected urological abnormalities; a prevalence of three per 1000 births. There was a male:female ratio of 2:1, the ratio was higher in obstructive than in intrinsic renal parenchymal lesions. Overall diagnostic sensitivity was 68-9% and positive predictive value 50....

The aim of this study is to increase awareness of rare presentations, diagnostic difficulties alongside management of conductive hearing loss and ossicular abnormalities. We report the case of a 13-year-old female reporting progressive left-sided hearing loss and high resolution computed tomography was initially reported as normal. Exploratory tympanotomy revealed an absent stapedius tendon and...
