The timing of the onset magnetochron M0r and its duration are disputed, reflecting both a limited set radioisotopic dates uncertain magnetostratigraphic correlations. We present chronostratigraphic framework for reversed polarity interval based on two chronometers (40Ar/39Ar, U-Pb) newly published paleomagnetic data from Qingshan Group, Jiaolai Basin, China. Bayesian modeling U-Pb zircon 40Ar/3...

Mutations in chromosome-helicase-DNA-binding protein 7 (CHD7) are identified as the main cause for CHARGE syndrome (coloboma, heart anomaly, choanal atresia, retardation, genital and ear anomalies). Most patients (55% to 85%) with CHARGE syndrome display developmental defects in the central nervous system (CNS), of which pathology and molecular mechanisms remain unclear. In this study, we repor...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2012-008165 DESCRIPTION The corpus callosum is a band of white matter connecting two cerebral hemispheres of the brain and responsible for the integration of motor, sensory and cognitive information. Its development starts in the first trimester of pregnancy, while m...

To assess the clinical utility of assessing embryonic brain and cranium by ultrasound at 7–10 weeks gestation. 1000 consecutive cases clinically indicated scans 7-10 were evaluated prospectively to evaluating cranial morphology in with bleeding, pelvic pain, previous pregnancy losses, those requesting for reassurance or an early scan. All embryos assessed transabdominal scans, supplemented tran...

neurocysticercosis, is the infection caused by the larval form of the tapeworm taenia solium. it is considered as the most common parasitic disease of the central nervous system and the most common cause of acquired epilepsy. this has primarily been a disease that remains endemic in countries with poor economy , but because of increased migration neurocysticercosis is being diagnosed more frequ...

abstract objective tumors of the central nervous system constitute the largest group of solid neoplasms in children and are second only to leukemia in their overall frequency during childhood. the main purpose of the present study is to determine the incidence, age, sex, location and histological diagnosis of cns tumors in children, less than 15 years of age, in the mofid children's hospital, i...

BACKGROUND Studies on birth weight and congenital anomalies in sub-Saharan regions are scarce. METHODS Data on child variables (gestational age, birth weight, sex, and congenital malformations) and maternal variables (gravidity, parity, antenatal care, previous abortions, maternal illness, age, medication, and malformation history) were collected for all neonates delivered at Ayder referral a...

BACKGROUND Several maternal and birth characteristics have been reported to be associated with an increased risk of many childhood cancers. Our goal was to evaluate the risk of childhood embryonal solid tumors in relation to pre- and perinatal characteristics. METHODS A case-cohort study was performed using two population-based datasets, which were linked through R software. Tumors were class...

The objective of this study was to characterize the prevalence, demographic risk factors, and malformations associated with agenesis and hypoplasia of the corpus callosum diagnosed in infancy. Using a large population-based registry of birth defects, we ascertained 630 cases of agenesis (ACC) and hypoplasia (HCC) of the corpus callosum diagnosed in the first year of life among 3.4 million live ...

Nowadays, in publications which dedicated to ultrasound in obstetrics a format that represents series of cases with their ultrasound images and clinical features and results is actual [1,2]. It is caused by difficulties of adequate prognosis of postnatal result, though exactly this prediction is the main task of prenatal consultation given to a pregnant woman with suspicion of abnormal developm...
