AbstractAs an indicator of fetal limb growth, change in the femur diaphysis length (FDL) between 15 and 38 weeks, menstrual age, has been evaluated in a longitudinal study of 20 normal fetuses, as determined by prenatal biparietal diameter, head circumference, and abdominal circumference growth patterns as well as postnatal pediatric assessment. Individual FDL growth curves were uniformly parabolic and followed very similar trajectories. The projected start points mean: 9.7 (± 1.5 SD) weeks for these curves were in complete agreement with embryologic data, and the curves themselves were well characterized by the Rossavik model [R299.5 (± 0.5 SD)%]. No differences between males and females were detected, and good agreement was obtained between the average longitudinal growth curve and the cross‐sectional growth curve derived from a previously studied data set.1Individual growth curve standards, determined from Rossavik models based on data obtained before 26.1 weeks, menstrual age, were within 7% of actual measurements in 94% of the 97 time points studied after 26 weeks. These results indicate that the Rossavik model and its associated individual growth curve standards can be used to evaluate the growth of the femur and thus provide an improved means for detecting skeletal dysplasias and fetal growth retardat

摘要:

AbstractA comprehensive prospective ultrasonographic study was performed in 93 patients to investigate gallbladder wall thickness and gallbladder volumes in various nonbiliary disease states. Without changes in gallbladder volume, mean gallbladder wall thickness was significantly increased (p0.01) in patients with liver cirrhosis, viral hepatitis, chronic congestive heart failure, hypoalbuminemia, and chronic renal failure (p<0.05) but not in patients with diabetes mellitus (n = 14) as compared to a control group. The present study confirms that a variety of nonbiliary disorders are associated with significant thickening of gallbladder walls and that this finding is not caused by incomplete gallbladder contraction.

摘要:

AbstractSpleen size in patients with infectious mononucleosis (IM) was measured using ultrasound, and the findings were compared with data obtained in cases of acute viral hepatitis (AVH). The size was expressed as the spleen index (SI) or the product of the longitudinal and transverse diameters, expressed in cm2, of the maximum cross‐sectional area of the spleen. A normal value obtained from 28 healthy individuals was 15 ± 7 cm2. The SI (mean ± SD) of patients with AVH and IM were 38 ± 7 cm2and 88 ± 26 cm2, respectively. When the SIs were divided into five groups–grade 0 (0–25), grade I (26–50), grade II 51–751, grade III (76–100), and grade IV (100+), 83.3% of the patients with AVH were graded as Grade 0 or I, whereas 88.9% patients with IM belonged to higher grades. Splenomegaly with a SI value over 75, grade III or IV, strongly suggests IM when IM and AVH are being considered in the absence of other potential causes of splenomegaly. Because the clinical features of IM sometimes resemble those of AVH, it is often difficult to differentiate the two entities. The measurement of spleen size could be a significant supplemental aid in the diagnosis of IM in primary medicine, before clinical data

摘要:

AbstractFetal echocardiography (real‐time and M‐mode) was used to evaluate a fetus at 20 weeks of gestation because intermittent bradycardia had been auscultated at 14 weeks of gestation. Real‐time examination of the four‐chamber view suggested ventricular disproportion with the left ventricle larger than the right, absence of the tricuspid valve, atrial and ventricular septal defects, and normal pulmonic and aortic outflow tracts. M‐mode quantitation demonstrated a dilated left ventricle, small right ventricle, dilated mitral valve, hypertrophy of the left ventricular wall, and normal outflow tract dimensions. Following the diagnosis of tricuspid atresia (type Ic), genetic amniocentesis was performed (46,XX). Intrauterine death occurred during the 28th week of gestation. Autopsy confirmed the echocardiographic
