81 children with three age group of 9, 12 and 14 in Th¸i Nguyªn received the cardiac ultrasound to evaluate the major parameters. The results have shown that cardiac size was gradually increased as increased age. The changes of cardiac size was correlated closely with the body weight in some parameters including the left cardiac ventricular diameter in the end of diastolic stage (Dd) and of systolic stage (Ds), the posterior wall thickness of left ventricular in the end of systolic stage (LWS)) and inter ventricular septal thickness.

PURPOSE: For the measurement of testicular volume, we tried to evaluate the differences between the 1) ultrasonographic and intraoperative ruler measurements, 2) the performances by a radiologist and urologic residents and also 3) the difference among the various formulas for volume calculation. MATERIALS AND METHODS: The sizes of 108 testes of 96 children (mean age: 4) were measured preoperatively for the length (L) and width (W) with using ultrasonography by a radiologist. These testes were also measured intraoperatively for the L, W and thickness (T) with using a ruler. Of the 108 testes, 57 testes were also scanned with using ultrasonography by urologic residents to measure the L, W and T. The testicular volumes were calculated with three different formulas: LxW2x0.52 (F1), LxWxTx0.52 (F2) and LxWxTx0.71 (F3). RESULTS: The mean volumes of the 108 testes measured with ultrasonography by the radiologist and with a ruler were 0.27+/-0.2ml vs. 0.87+/-0.56ml, respectively (p<0.001). The mean difference between the volumes measured with ultrasonography and a ruler was 0.61+/-0.47ml. The mean volume of 57 testes measured with ultrasonography by the urologic residents was not significantly different from that measured by a radiologist (p=0.235), and it was also smaller than the volume measured with an intraoperative ruler (p<0.001). CONCLUSIONS: The testicular volume in children was much underestimated by ultrasonography with statistical significance. Therefore, the possibility of underestimation must be considered in clinical settings. The testicular volumes measured with ultrasonography by the radiologist and by the urologic residents had no significant difference.

Background:The dimension and function of kidney have close relationship. In the developing countries, the index on kidney dimension of children has rather fully studied. In Viet Nam, most of studies only conducted on adults. Objectives:This study aims to determine the ultrasound kidney dimension and the correlation of kidney length and age, weight and height of children aged from 6 to 8 years old. Subjects and method: The data was obtained from a prospective study on 180 normal children at age from 6 to 8 years. Each kidney was measured length, width , thickness, and parenchymal thickness, and the mean values were recorded. The relationship of kidney length with age, body weight, body height were also taken. Results: Kidney dimension was increased by age. The average ultrasound kidney dimension:+ Right kidney: At 6 years old: Boy: length: 72.8\xb14; width: 31.2\xb13 ; thickness: 33.9\xb12 ; Girl: length: 69.8\xb15; width: 30.4\xb12 ; thickness: 32.7\xb12. At 7 years old: Boy: length: 75.2\xb14; width: 31.9\xb12; thickness: 33.8\xb13; Girl: length: 75.8\xb15; width: 32.0\xb12; thickness: 32.9\xb14; + Left kidney: At 6 years old: Boy: length: 73.9\xb15; width: 33.7\xb13 ; thickness: 34.9\xb12 ; Girl: length: 71.1\xb14; width: 32.4\xb13 ; thickness: 32.4\xb16. At 7 years old: Boy: length: 77.7\xb13; width: 33.8\xb13 ; thickness:34.7\xb12; Girl: length: 76.9\xb17; width: 32.0\xb12; thickness: 33,9\xb15; The kidney length, kidney weight, kidney volume of boys were bigger than girls, and the difference was significant (p<0.05). Conclusion: The kidney length correlated strongly and positively with body weight, body height and age.

To observe the normal development of prostate, we measured the size of 114 prostates from infant to adolescent by trans-abdominal ultrasonography. The volume of prostate was calculated using the formula for ellipsoid objects. In infants, the prostates were uniformly flat triangular column and became elliptic cylinder in shape with the age. The width, thickness and length of the prostate showed linear growth pattern with the age. The mean volume of the prostate was 0.28 ml in infant and 6.09 ml in 15-16 years old. The prostate grew slowly with the age under 9-10 years old or with the height under 130 cm and thereafter grew rapidly with the age or with the height. There were good correlations between the prostatic volume, the age and the height.

PURPOSE: The purpose of this study was to establish the guidelines for normal splenic length by sonographic measurement. MATERIALS AND METHODS: In 481 children (age range : 2-16years, M:F=1.5:1), abdominal sonography for the purpose of health screening was carried out, and the greatest length of spleen between the dome and tip was measured. Correlation and regression analysis was used to determine whether the relationship between splenic length and a patient's age, height, weight and body surface was statistically significant. RESULTS: The length of the spleen gradually increased according to age. Correlation and regression analysis showed significant positive correlation (p<0.0001) between splenic length and age (r=0.610) height (r=0.630), weight (r=0.598), and body surface (r=0.628). CONCLUSION: From the mean values of spleen length in children, an index useful for clinical application might be derived.

Ceftriaxone is known to induce a precipitation in the gallbladder that mimics gallstones on sonography in the children and adults. "Biliary pseudolithiasis" is now used to describe this reversible, benign complication accompanying ceftriaxone therapy. It is important to be aware of this adverse effect because it does not need any specific treatment. To our knowledge, there have not been any reports of CT findings of ceftriaxone-associated biliary pseudolithiasis in literature. We herein report two cases of ceftriaxone-associated biliary pseudolithiasis with sonographic and CT findings, which were completely resolved after the cessation of ceftriaxone therapy.

Isolated small bowel intussusception accounts for 10% of all pediatric intussusception. It is more common in children older than 2 years of age. Presentation usually is with vomiting and abdominal pain. Currant jelly stool and palpable mass are less frequent than typical intussusception. There are few reported cases of children with transient small bowel intussusception. We describe 3-year-old boy presented with intermittent cyclic crampy abdominal pain for 6 months was diagnosed as having recurrent transient small bowel intussusception by abdominal ultrasonography and small bowel series.
