No epidemiological surveys have examined risk factors related to the death of very low birth weight infants (VLBWIs) in Japan. The objectives of this study were to examine the death rate and fatalities related to complications among VLBWIs, and to analyze factors possibly determining the death of VLBWIs. The subjects of this study were 811 VLBWIs admitted to the Neonatal Care Center of Niigata ...

among 2357 prenant women at tehran valiasr hospital, 99 women under 18 years with their 102 neonates were evaluated retrospectively during aprill 1999 to april 2000. frequency of adolescent pregnancy was detected in 41.5 per 1000 live birth 7 (7.1%) of mothers had preeclampisa, 7 thyroidal diseases, 3 valvular heart diseases, 2 urinary tract infections and 20.3% of women had prolonged rupture o...

Background & Aims: Chromosome abnormalities are a major cause of miscarriage and neonatal mortality. The present study aimed to determine the association of fetal and parents chromosomal abnormalities with congenital anomalies. Methods: A cross-sectional study was performed in a tertiary referral center (Afzalipour Hospital) over 16 months period (2011-2012). The study groups consisted of 77 fe...

this study briefly reviews the heart abnormalities in diverse intracranial pathologies, including strokes, spontaneous and traumatic subarachnoid hemorrhage and intracranial hemorrhage, and presents the results of a one-year prospective study of heart abnormalities in patients with moderate to severe head injuries and subarachnoid hemorrhage. different abnormalities such as: qt -interval, t -wa...

this study was conducted to assess the incidence of abnormalities of ventricular depolarization (late potentials) in children with sinus rhythm after open heart surgery and their relation to spontaneous ventricular tachycardia. open heart surgery, particularly operations involving ventriculotomy, may predispose patients to the development of ventricular tachycardia (vt) or ventricular fibrillat...

ventricular arrhythmias are one of the most important causes of annual deaths in the world, which may lead to sudden cardiac deaths. accurate and early diagnosis of ventricular arrhythmias in heart diseases is essential for preventing mortality in cardiac patients. ventricular activity on the electrocardiogram (ecg) signal is in the interval from the beginning of qrs complex to t wave end. vari...

Genes regulate the development of fertilised egg into the inner cell mass (which will become the embryo, fetus and, eventually, baby) and the trophoblast (which will become the placenta). Defects in the genes that regulate these processes lead to a wide range of embryonic, fetal and neonatal defects, from minor cosmetic abnormalities, to such severe defects disasters that a pregnancy miscarries...

Editorial Birth defects – or by according to the World Health Organization's (WHO) term: congenital anomalies – are structural, functional and/or biochemical-molecular defects present at birth whether detected at that time or not (Figure 1). Among different categories of birth defects, congenital abnormalities, i.e. structural-morphological defects represent the largest one. Congenital abnormal...
