Thinning of parietal bone bilaterally is extremely rare but well known phenomenon. Approximate prevalence is 0.4-0.5% according to radiological scans, case reports and anthropologic researches. Even though biparietal osteodystrophy occurs mostly in over 60-year-old women, it shows no special association with race or geographical area tendency. Current definition was changed by understanding tha...

With the aim of determining fetal growth kinetics, prenatal data were analysed which had been longitudinally collected in the framework of a perinatal growth survey. The sample comprised 238 singleton normal pregnancies, selected in Genoa and Turin (between 1987 and 1990), and repeatedly assessed by ultrasound scans (five to nine per pregnancy). Five morphometric traits were considered: BPD (bi...

Ninety eight newborn infants weighing less than 1500 g at birth and with gestational ages from 26 to 32 weeks were followed prospectively. They were grouped according to real time ultrasound scans in the neonatal period: infants in group A (n = 20) had periventricular haemorrhage (PVH) and normal ventricles; infants in group B (n = 26) had PVH and dilated ventricles (none with clinical hydrocep...

TERRY J. DUBOSE, MS, RDMS, The fetal head is three dimensional (3D). As 3D sonography becomes a clinical reality, there is a need to describe standard biometric parameters by which the head shape, proportions, and volumes may be measured and analyzed. This particular study presents measurements and methods that are applicable to newer 3D imaging systems. These measurements will provide consiste...

Comment. Possessing an APOE ε4 allele is the most important genetic risk factor yet identified for sporadic AD and also significantly lowers onset age. It is therefore striking that despite their young age at onset, only 2 of our 10 biparietal patients were ε4-positive. While we believe that a lack of association between biparietal AD (or posterior cortical atrophy AD) and APOE ε4 genotype has ...

Monitoring fetal growth in utero is crucial to anomaly diagnosis. However, current computer-vision models struggle accurately assess the key metrics (i.e., head circumference and occipitofrontal biparietal diameters) from ultrasound images, largely owing a lack of training data. Mitigation usually entails image augmentation (e.g., flipping, rotating, scaling, translating). Nevertheless, accurac...

The aims of the current study are to build an equation predict gestational age (GA) and compare ultrasound parameters indicative delivery in healthy English Bulldog bitches subjected elective cesarean section. Sixteen pregnant female dogs were included study. Inner chorionic cavity (ICCDD) biparietal (BPD) diameters measured at 30 50 days after artificial insemination, respectively, estimate GA...

SUMMARY Determination of gestational age have several usages in obstetrics and gynecology. The relation between Biparietal Diameter and gestational age has determined in this research using real time Sonography. 904 Iranian pregnant women between 12-40 weeks of gestation with accuratic last menstrual period and without the history of diabetes mellitus, hypertension, renal disease and Fetal an...

We describe a case of catatonic stupor following simultaneous biparietal infarction. The patient recovered, a result not previously described in catatonia caused by this pattern of cerebral infarct.

Bu çalışmada, Karadeniz’in önemli antik kentlerinden birisi olan Sinop’ta Balatlar Kilise popülasyonu içerisinde 2006 yılında tespit edilen ve 18. yüzyıla ait olduğu düşünülen bir kafatası incelenmiştir. Yapılan makroskobik tomografik incelemelerde, ileri erişkin bu bireyin 3. derece bilateral osteodistrofiye sahip anlaşılmıştır. Simetrik biçimde parietalin her iki yanında yer alan lezyon, özel...
