1.Right Ventricular Area, Dimension, and Volume Measured by Two-dimensional Echocardiography in Normal Children.
Journal of the Korean Pediatric Society 1994;37(10):1340-1349
The usefulness of two-dimensional echocardiography to measure the right ventricular volume was assessed in 58 normal children (mean age 5 years and 3 months). From the apical 4-chamber view (A4CV), the subcostal RV sagittal view (SCRVSV), the subcostal right anterior oblique view (SCRAOV), and the subcostal RV coronal view (SCRVCV), the dimensions and areas of the right ventricle were measured. The right ventricular volumes and ejection fractions were calculated from these data by pyramid model and single plane area/length method. We could obtain subcostal right ventricular sagittal view in 98%, apical 4-chamber view in 90%, subcostal right anterior oblique view in 79%, and subcostal right ventricular coronal view in 71% of our children. The areas and dimensions correlated with all growth indices, such as age, height, weight, and body surface area. In general the areas showed higher correlation with body surface area, and dimensions with height. correlations of parameters obtained from the subcostal right anterior oblique view and subcostal right ventricular sagittal view with the growth indices were better than those of the subcostal right ventricular coronal view. The calculated right ventricular volume and ejection fraction showed a great varibility depending on the model used. The right ventricular volume calculated by pyramid model correlated better with the growth indices than that by single plane area/length method. the right ventricular volume calculated from the apical 4-chamber view dimension and the subcostal right ventricular sagittal view area by pyramid model is the model which showed the best correlation with growth indices. Right ventricular ejection fraction did not change with any growth indices. Among the right ventricular volumes and ejection fractions by single plane area/length method, the volume(59.9+/-29.9 ml/m(2)) and ejection fracton (58.7+/-10.9%) from the subcostal right anterior oblique view were similar to those (51.0+/-17.3ml/m(2), 51.3+/-10.2%) calculated from the apical 4-chamber view dimension and the subcostal right ventricular sagittal view area by pyramid model. The subcostal right anterior oblique view reflects three parts of the right ventricle. Its area and dimension are well correlated with growth indices. Also the right ventricular volume and ejection fraction obtained by single plane area/length method using the subcostal right anterior oblique view correlate with the growth indices. Therefore the subcostal right anterior oblique view is the most valuable single view representing the right ventricle.

We report a case of hepatocellular carcinoma presented with severe hypoglycemia. Computerized tomography and ultrasonography revealed a massive bilateral tumor with portal vein thrombosis. The levels of IGF-I (113 ng/mL) and IGFBP- (815 ng/mL) measured in the plasma, were lower than normal range. There was strong immunoreactivity of IGF- and IGF-I in immunohistochemical stain of tumor cells.

There are many complications related to paralyzed patients. Heterotopic ossification in pressure sore patients is reported to be rarely developed, but once it occurs, it frequently causes joint stiffness which may aggrevate the pressure sore wound. This paper was based on a clinical study of heterotrophic ossification in 6 quadriplegic and paraplegic patients from 1988 to 1997 at St. Paul's Hospital. All were males aged between 22 and 58 years (mean age, 45.5 years). The sites of pressure sore were in the ischial and trochanteric areas. Heterotopic ossification had developed around the hip joint and the ischial area. The mean onset time was 3.6 years (minimum 10 months maximum 8 years) after trauma. Plain X-ray, bone scan CT and pathological examination were helpful in confirming the diagnosis of heterotopic ossification. The mechanism of heterotopic ossification is not exactly known, but chronic trauma or inflammation could be one etiology. There are still many difficulties in management of heterotopic ossification, but prevention is the most important treatment.

Microsporum ferrugineum was the most common cause of tinea captis in Korea until the middle of the 1970s, but this organism has been only rarely isolated from the scalp ringworm during recent years. We report, three cases of tinea capitis occurring in a 2-year-old male, a 10 year-old female and a 5-year-old male. From all three patients, Microsporum ferrugineum was isolated.
