1.Diagnosis of Ventricular Septal Defect by Pulsed Doppler Echocardiography.
Korean Circulation Journal 1986;16(1):137-142
This study was performed to assess the accuracy of pulsed Doppler echocardiographic(PDE) diagnosis of ventricular septal defect(VSD). 119 children with congenital heart disease, aged 9 months to 17 years, admitted to our hospital for cardiac surgery, were studied. These children had VSD(56), ASD(18), PDA(43), PS(1) and Cortriatrium(1). A specific PDE diagnosis of VSD can be made by following the turbulent VSD jet(TVJ) through the septum, and a PDE diagnosis of VSD was made in 53 out of 56 patients(95%) proven by catheterization and operation. There were two false positive PDE diagnosis of VSD by PDE, were proven to be perimembranous VSD at operation, and 3 children who were classified into subarterial infundibular VSD by PDE, were proven to be perimembranous VSD at operation. PDE seems to be a very useful tool in preoperative evaluation of VSD.

2.Clinical Significance of the Routine "Dipstick" Urinalyses in Pediatric Inpatients.
Yeungnam University Journal of Medicine 1984;1(1):115-120
To find clinical significance of routine “dipstick” urinalysis on admission, we analyzed the results of the “dipstick” urinalyses performed in 844 patients admitted to the pediatric department of Yeungnam University hospital from May 1, 1983 to October 31, 1984. Ketonuria, proteinuria, hematuria and glucosuria were found in 9.5%, 4.9%, 2.4% and 1.1% of the patients respectively. There were no significant differences by sex, age and presence of fever. However, proteinuria and ketonuria were found more frequently in the patients with dehydration (p<0.05). All of the patients with proteinuria and ketonuria showed negative results on follow up. However, among 13 patients with hematura, 9 patients showed negative results and 4 patients had persistent hematuria on follow up. These 4 patients were found to have chronic pyelonephritis (2), asymptomatic urinary tract infection (1) and benign recurrent hematuria (1). This routine “dipstick” urinalysis on admission seems to be simple test which is useful in detecting unrecognized kidney and other urinary tract disease.

3.A Clinical Study of Mycoplasma Pneumoniae Pneumonia.
Yeungnam University Journal of Medicine 1989;6(1):21-29
A clinical study was made on 71cases of Mycoplasma Pneumoniae Pneumonia from March, 86 to February, 89. The results were as follows; 1. Among the 315 cases of pneumonia, the incidence of mycoplasma infection was 22.5% 2. The peak incidence of age was between 5 to 9years of age (53.5%) 3. The sex ratio of male to female was 1.3:1 4. Monthly distribution showed relatively high frequency from October to January (59.2%) 5. Most common clinical symptoms were cough (98.6%) and then followed by fever (49.3%), coryza (19.7%). Rales were the most common finding (95.7%) and followed by pharyngeal injection (49.3%) and wheezing (18.3%) 6. The leukocyte counts in peripheral blood were most common in the range of 5000-10000/mm³ (47.9%) and the ESR was increased in 57.7%, and positive CRP cases were 87.3% 7. The most common radiologic finding of pulmonary infiltration was interstitial infiltration (45.1%) and then followed by disseminated lobular (39.4%) and lobar pneumonia (15.5%) 8. There are a few cases associated disease or complication: otitis media (5.6%), hepatitis (4.2%) acute glomerulonephritis, bronchial asthma and sinusitis (2.8%), thrombocytopenia (1.4%)

We compared the efficacy of each modality of treatment group in reducing the frequency of coronary artery abnormalities and change of clinical courses in children with Kawasaki disease in the children of 81 cases who were admitted in pediatric department of Yeungnam University Hospital from September 1985 to August 1990. Group A (37 cases)-aspirin alone, Group B (44 cases)-intravenous gammaglobulin (400 mmg/kg/day) for 5 consecutive days, plus aspirin. We studied the frequency of echocardiographic abnormalities, the duration of fever, and changes in the total white blood cell counts, platelet counts, ESR and CRP value at 1, 2 and 3 weeks of the illness and compared the results between the two groups. The results were as follows. 1) There was no significant intergroup difference in age and sex ratio. 2)The duration of the febrile period after the initiation of the therapy was significant shorter in group B (2.5±1.2days) than in group A: (5.2±3.5 days) (p<0.01). 3) No significant difference was noticed in the WBC and platelet counts in two groups as measured at admission day, 1 and 2 weeks of the illness, however, at 3weeks of illness significant difference was noted. 4) The CRP values measured at 1,2 and 3 weeks after treatment were significantly lower in group B (2.42±1.8, 2.00±1.2, 1.16±1.0) than in group A (7.22±5.3, 5.25±3.9, 1.85±1.2) respectively (p<0.01). 5) In 2D-Echocardiogram, coronary artery dilatation was more frequent in Group A than in Group B at 6month of illness (p<0.01). In conclusion, intravenous gammaglobulin therapy was effective in the shortening of the duration of fever and in the anti-inflammatory action and somewhat effective in prevention of coronary artery aneurysm.

For the determination of the usefulness of the pulsed Doppler echocardiographic diagnosis of ASD. We evaluated 185 children with congenital heart disase by subxiphoid approach. ASD was diagnosed when abnormal flow was recorded in right atrium. ASD was proved by surgery in 33 of 185 children with congenital heart disease, and all children had sugical correction of their heart deformities. On pulsed Doppler echocardiographic exmination, abnormal flow was recorded in 32 of the 33 children with ASD and 3 of 152 children without ASD. This pulsed Doppler echocardiographic diagnosis of ASD by abnormal flow in right atrium has sensitively of 97% and specificity of 98%. High correlation was found between the estimates of Qp/Qs ratio by Doppler and Fick method(r=0.90, P<0.01). So we concluded that pulsed Doppler echocardiographic diagnosis of ASD was specific and sensitive method and careful pulsed Doppler echocardiographic examination may avoid the unnecessary cardiac catheterizetion in patients with ASD.

Mass electrocardiographic (ECG) examination was performed on 13,801 children (male 7,526 and female 6,275) of elementary and middle school in Taegu from May 1. 1986. to April 30. 1987. We read their ECG according to the “pediatric Electrocardiography”1) The results were as following: The incidence of ECG abnormality was 1.05% (male 1.3% and female 0.75%). Fifty eight children (0.42%) had atrial and ventricular hypertrophy; two right atrial hypertrophy, five left atrial hypertrophy, thirty five right ventricular hypertrophy and sixteen left ventricular hypertrophy respectively. Ectopic beats occurred in 25 children (0.18%); They were atrial in 12 children, ventricular in 8 children and junctional in 5 children. There were 62 children (0.45%) of conduction disturbance; They were first degree atrioventricular (A-V) block in 21 children, type I second degree A-V block in 1 child, A-V dissociation in 1 child, right, right bundle branch block in 36 children, left bundle branch block in 1 child and WPW syndrome in 2 children. Nonspecific ST, T changes and sinus tachycardia were found in 3 and one children respectively.
