BACKGROUND: Noninvasive estimation of pulmonary artery pressure is an important component of echocardiographic studies. A number of methods are available for estimation of pulmenary pressure, each with varying degrees of reported accuracy. To assess accuracy and difficulties, noninvasive pulmonary artery pressure estimates were performed in infants and children with congenital heart diseases. METHODS: Noninvasive estimates from 8 methods were compared with catheterization measurements. Systolic pressure was estimated by the Burstin method and from perak tricuspid regurgitation velocity, and also from systolic pressure gradients through the VSD(ventricular septal defect) and PDA(patent ductus arteriosus). Mean pressure was estimated by acceleration time divided by ejection time measured from Koppler spectrum obtained at the right ventricular out flow tract. Diastolic pressure was estimated from pulmonary regurgitation velocity spentrum at end-diastolic, and also from diastolic pressure gradient through the patent ductus arteriosus. RESULTS: IN systolic pressure, Burstin and tricuspid regurgitation velocities estimates correlated significantly(r=0.92, 0.90 respectively), whereas VSD and PDA estimates correlated less well with catheterization estimates(r=0.83, 0.65 respectively). The mean pressure, measured from RVOT(right ventricular outflow tract) Doppler spectrum corresponded well with catheterization pressure(r=0.89), whereas those obtained from the main pulmonary artery correlated less well(r=0.74). The diastolic pressure estimates from pulmonary regurgitation velocity spectrum, revealed good correlation(r=0.79), but those from diastolic Doppler spectrum at PDA correlated less well with catheterization estimates(r=0.63). CONCLUSION: All of eight Doppler echocardiographic methods seemed to be easily performable for estimation of pulmonary artery pressure. But, the degree of accuracy was variable. Because a pressure estimante from only a single method may be in error, care should be taken in combining use of other(one or two) methods.

PURPOSE: For evaluation of the growth hormone and cortisol responses to insulin stimuli in children with short stature, the human growth hormone secretion and cortisol level was monitored 30 and 60 minutes after insulin infusion by intravenousely. METHODS: The inclusion criteria of children for this study were that the height was below 3 percentile compare with the same sex and age children, bone age was younger more than one year of chronologic age, and insulin and L-dopa induced growth hormone secretion was below 10ng/mL. There were 10 children compatible with this criteria(group A) and 11 children was selected for control group(group B). Serum concentration of growth hormone was determined just before intravenous infusion of 0.1U/kg insulin and then 30 and 60 minutes after insulin infusion. Serum level of cortisol was determined simultaneously with the growth hormone but skip the level of the 30 minutes after insulin infusion. Serum glucose level was monitored on every time sampling the blood for determined growth hormone and cortisol level. Serum level of growth hormone and cortisol were determined by radioimmunoassay. RESULTS :The serum glucose concentration were decrease to under 50% of baseline level on 30 minutes after insulin infusion in A and B group. The serum growth hormone level before insulin infusion was 2.5+/-1.78ng/mL and changed to 2.2+/-1.69 ng/mL on 60 minutes after insulin infusion in group A. In group B, the serum growth hormone level alteration before and on 60 minutes after insulin infusion was from 5.5+/-6.67ng/mL to 12.6+/-7.91ng/mL. The serum concentration of cortisol was changed from baseline level 10.7+/-7.10, 7.9+/-3.98microg/dL to 16.7+/-11.47, 26.1+/-3.59microg/ dL on 60 minutes after insulin infusion in group A and B respectively, but some cases in group A show a little increase in cortisol level. CONCLUSION: On the basis of this study, it is suggested that the deficiency of growth hormone secretion is related to cortisol concentration in peripheral blood. But for more detailed assessment of this association, follow up studies will be needed in more cases.

PURPOSE: We reviewed 5 years worth of experience with peritoneal drainage and dialysis in infants who underwent open heart surgery. The aim of this study was to investigate the effect of peritoneal drainage and peritoneal dialysis on fluid balance and several parameters of intensive care. METHODS: Six(10%) of 60 consecutive infants who underwent open heart surgery required peritoneal dialysis during peritoneal drainage. Simple peritoneal drainage was performed in the remaining 54 infants. The silicone rubber peritoneal dialysis catheter was inserted into the center of abdominal cavity just after operation, and subsequent peritoneal drainage was maintained during intensive care. RESULTS: Mean age of the study group was 0.48+/-0.21 years(M: F=32: 28). Early postoperative mortality amang the infants with congenital heart disease was 1.6%. Total amount of output was 7.0+/-2.28mL/kg/hr, urine output 5.14+/-2.9lmL/kg/hr, pleural fluid 0.80+/-0.5lmL/kg/hr, and peritoneal fluid 1.20+/-0.90mL/kg/hr. The ratio of output to intake(O/I) was 1.06. None of the complications required early termination of peritoneal drainage or peritoneal dialysis. Hemodynamics and pulmonary function were maintained steadily during postoperative intensive care. CONCLUSION: The early institution of peritoneal drainage and peritoneal dialysis in infants with congenital heart disease after cardiac operations not only removes fluid, thus easing fluid restriction, but may also improve cardiopulmonary function.

Total cholesterol and triglyceride were measured in sera of 40 cases of hypertension, 22 cases of myocardial infarction, 14 cases of cerebral thrombosis, 18 cases of subarachnoidal hemorrhage and 30 cases of normal control in Chungnam national University Hospital from October 1980 to September 1981, and the results are as follows; 1) The mean serum total cholesterol and triglyceride levels in normal control group are 153.57+/-40.60mg% and 150.82+/-51.76mg%. 2) The age incidence of these diseases were highest in 6th decade. 3) Serum cholesterol levels of myocardial infarction, hypertension, cerebral thrombosis and subarachinoidal hemorrhage group were higher than that of normal control group. 4) Serum triglyceride levels of acute myocardial infarction and hypertension were significantly higher than that of normal control group, but there is only slightly increases in cerebral thrombosis and subarachinoidal hemorrhage. 5) In general, serum lipid levels are higher in cardiovascular diseases(hypertension and myocardial infarction) than cerebrovascular diseases(cerebral thrombosis and subarachnoidal hemorrhage). 6) Serum Cholesterol and triglyceride levels decreased by administration of pancreatic mucopolysacharide for 1 or 2 months. In conclusion, it seems that high serum cholesterol and triglyceride level may play and important risk factor in development of hypertension and myocardial infarction.

PURPOSE: Mycoplasma pneumoniae pneumonia (MP) is associated with the exacerbation, timing, and onset of asthma. The goal of this study was to elucidate the impact of MP on eosinophil-related hyper-reactive amplification in atopic children. METHODS: We studied 48 patients with MP (26 atopic, 22 non-atopic), between 3 and 12 years of age. Serial changes in blood eosinophil counts, serum interleukin-5 (IL-5), and serum eosinophil cationic protein (ECP) levels were measured in atopic and non-atopic children with MP upon admission, recovery, and at 2 months post-recovery. Serum IL-5 and ECP levels were measured by enzyme-linked immunosorbent assays; eosinophil counts were measured using an autoanalyzer. RESULTS: Serial changes in serum IL-5, ECP, and total eosinophil counts were significantly higher in atopic patients, relative to non-atopic controls (P< or =0.001). Serum IL-5 and ECP levels were significantly higher in atopic patients at all three time points tested, while eosinophil counts were higher in the clinical recovery and follow-up phases, but not in the acute phase. Furthermore, among atopic patients, serum ECP levels were significantly higher in the recovery and follow-up phases than in the acute phase. CONCLUSIONS: The present study demonstrated significant differences in eosinophil counts, serum IL-5, and serum ECP levels between atopic and non-atopic children with MP at admission, recovery, and 2 months after clinical recovery. These outcomes are suggestive of eosinophil-related hyperreactivity in atopic children, with this status maintained for at least 2 months after MP.

West Nile virus (WNV) is a mosquito-borne zoonotic pathogen that has spread throughout Europe and the United States. Recently, WNV spread to East and Southeast Asia, and great efforts have been made in South Korea to prevent the spread of WNV from neighboring countries. In this study, we diagnosed the first case of WNV in pigeons (Columba livia domestica) residing in cities using a competitive enzyme-linked immunosorbent assay and confirmed it with nested reverse transcription polymerase chain reaction analysis and sequencing. This is the first report to provide convincing evidence that WNV is present within South Korea.

Although there has been recently noted a nation-wide spread of Trichophyton verrucosum infection in cattle associated with promoted stock raising and dairy farming, there were no case reports in Korean dermatologic literature describing the characteristic clinical features of tinea barbae caused by that particular fungus. We report 3 cases of tinea barbae due to T. verrucosum that developed in male stock farmers breeding cattle. One Patient acted 37, experienced acutely inflamed bo99y tumors on the chin and sub-mandible. The others aged 43 and 46 experienced inflammatory lesions with multiple follicular pustules, crusts and loss of hairs on their upper lips. They were successfully treated with oral griseofulvin and local antifungal ointment combined with short-term oral antibiotics or corticosteroid for about one month.
