إيجاد العلاقة بين استمرار الثلمة في موجة الشريان الرحمي و تطور حالة نقص نمو الجنين داخل الرحم (IUGR) , و ارتفاع الضغط المحرض بالحمل (PIH) , إظهار هل للإيكو دوبلر دور في تمييز الحمول عالية الخطورة؟
To find out the correlation between persistence of uterine artery notch and development of intrauterine growth retardation (IUGR) and pregnancy induced hypertension (PIH), and to see if Doppler assessment can help identify high risk pregnancies.

The study was performed in 64 children aged 6 months to 5 years had
ventricuLar septal defect. Systolic pressure in the right ventricle and
Pulmonary Hypertension were determined by two ways.
1- From arteriovenous shunt via ventricular septal defe
ct the
correlation ratio of doppler echo cardiographic catheterization
values was %76.
2- From systolic regurgitation via the tricuspid valve the correlation
was %97.
In this study 500 obese pregnant women and 250 non-obese pregnant women
(Group of Control) were followed up to prove the role of obesity as a high risk
factor on the incidence of (P.I.H.). We found that:
1. There is a considerable increase in the
incidence of (P.I.H.), which was
proportional to the grade of obesity in the main group. The incidence of P.I.H.
was : %15.38 in grade 1, %26.42 in grade 2 and %42.22 in grade 3 of obesity
(Vs. %6.4 in the control group).
2. There is a considerable increase in the incidence of (P.I.H.) among the obese
pregnant women, especially when they are 36-45 years old (%32.39 Vs. %6.45
in control group).
So that it is advisable to screen all obese pregnant women especially when they
are 36-45 years old and consider them as a high risk group for the indicence of
(P.I.H.).
Extractive summarization has been the mainstay of automatic summarization for decades. Despite all the progress, extractive summarizers still suffer from shortcomings including coreference issues arising from extracting sentences away from their orig
inal context in the source document. This affects the coherence and readability of extractive summaries. In this work, we propose a lightweight post-editing step for extractive summaries that centers around a single linguistic decision: the definiteness of noun phrases. We conduct human evaluation studies that show that human expert judges substantially prefer the output of our proposed system over the original summaries. Moreover, based on an automatic evaluation study, we provide evidence for our system's ability to generate linguistic decisions that lead to improved extractive summaries. We also draw insights about how the automatic system is exploiting some local cues related to the writing style of the main article texts or summary texts to make the decisions, rather than reasoning about the contexts pragmatically.
Renal artery stenosis is an important clinical entity. its
importance lies in that it may be a treatable cause of
hypertension, and it is -when progress- a cause of chronic
renal failure. The causes of renal artery stenosis are
numerous, the most
common are: atherosclerosis and
fibromuscular dysplasia (accounts for more than 95% of
cases). Digital Subtraction Angiography (DSA) is the standard
reference in the radiologic diagnosis of renal artery stenosis,
but it carries the risk of being invasive procedure. Doppler
ultrasound is used in the evaluation of the renal arteries, and
it has the advantage of being non-invasive and inexpensive.

Spontaneous coronary artery dissection (SCAD) is an infrequent and often missed diagnosis among patients presenting with acute coronary syndrome (ACS). Unfortunately, SCAD can result in significant morbidities such as myocardial ischemia and infarcti
on, ventricular arrhythmias and sudden cardiac death. Lack of angiographic recognition from clinicians is a major factor of under-diagnosis. With the advent of new imaging modalities, particularly with intracoronary imaging, there has been improved diagnosis of SCAD. The aim of this paper is to review the epidemiology, etiology, presentation, diagnosis and management of SCAD.
