The purpose of the present communication is to emphasize again the value in obstetric procedures of lateral roentgenograms of the pelvis and to describe a newly modified technic which appears to be a definite improvement on that hitherto used in this clinic. Eight years ago, one of us published a communication' on this subject and pointed out that roentgenograms of the pelvis taken laterally po...

BACKGROUND Many studies have emphasized on fetal pinna measurements and morphologic features to use this structure as an additional marker for fetal chromosomal anomaly. OBJECTIVES To assess relationship between fetal pinna length and gestation age and develop a nomogram. To assess relationship between fetal pinna length and head circumference and biparietal diameter. METHODS Fetal pinna me...

BACKGROUND Common fetal parameters for gestational age (GA) estimation have pitfalls especially in advanced pregnancy and pregnancy complicated by fetal structural anomaly. OBJECTIVE To assess the relationship between umbilical cord size and gestational age of the fetus. SUBJECTS AND METHODS A sonographic cross sectional study involving 300 pregnant women with GA between 14 weeks to 40 week...

The present study evaluated the effectiveness of sildenafil citrate (SC) to improve placental and fetal growth in a diet-induced rabbit model of intrauterine growth restriction (IUGR). Pregnant rabbits were fed either ad libitum (Group C) or restricted to 50% of dietary requirements (Group R) or restricted and treated with SC (Group SC). The treatment with SC improved placental development by i...

OBJECTIVE To construct charts offetal biometries at Sukhothai Hospital. MATERIAL AND METHOD One hundred and fifty-one pregnant women attending the antenatal care clinic, Sukhothai Hospital were recruited and received ultrasonographic examinations every four weeks until delivery. RESULTS Biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), and femur length (FL) w...

A series of 50 consecutive children with premature sagittal synostosis is reported. All were treated surgically; 43 were male, 47 were leukodermic and two are siblings. In the pre-operative examination, the head shape, skull measurements and radiologic findings were evaluated; 38 children were operated on before six months of age and 12 of them, between six and 12 months of age. The surgical te...

We used single-pulse transcranial magnetic stimulation (TMS) to study visuospatial attention. TMS was applied over one hemisphere, or simultaneously over both the right and left posterior parietal cortex (PPC), at two different interstimulus intervals (ISI) during a visual detection task. Unilateral TMS over the right and left PPC, respectively, impaired detection of contralateral presented vis...
