The purpose of this study w-s to predict the respose to the chincap therapy from the initial cephalometric measurements and to obtain the indication of chincap therapy. 40 patients selected for this study were classified into two groups by the occlusal stability after completion of permanent dentition and the iiu4n ovement of facial profile, after chincap therapy. One was g response group which consisted of 25 children and the other was poor response group with 15 patients. Various measurements of the craniofacial structure in the initial lateral cephalogram were calculated and analyzed by t-test and discriminant analysis. The results were, as follows 1. Good response group had more horizontal growth pattern in initial stage of treatment, and the contributing measurements were Bjork sum, anterior-posterior facial height ratio, gonial angle, lower gonial angle and occlusal plane to AB plane angle. 2. The critical points and predictive values of the influential skeletal measurements were calculated. 3. The discriminant function was obtained from three. major influential measurements; Bjork sum, gonial angle and occliml plane to AB plane angle, and this function could discreminate correctly in 85% of this samples.

This study examined the relations between degree of posterior dental compensation and skeletal discrepancy in Class III malocclusion. The pretreatment lateral cephalograms and dental casts of 87 skeletal Class III adults were selected to provide a random sampling of skeletal Class III malocclusion. Skeletal discrepancy was described with ANB angle, Wits appraisal, SN-Mn plane angle, FMA and ratios of basal arch width. Degree of posterior dental compensation was described with maxillary intermolar angle, mandibular intermolar angle and sum of intermoloar angle. The relationships between skeletal discrepancy and degree of posterior dental compensation were analyzed with simple correlation analysis, stepwise multiple regression analysis. The results were as follows : 1. A strong association was found between the variation in the anteroposterior measure, ANB angle and the variation of posterior dental compensation measures, sum of intermolar angle and mandibular intermolar angle in skeletal Class III malocclusion. 2. There was no statistically significant relationship between the variation in the vertical measures and the variation of posterior dental compensation measures in skeletal Class III malocclusion. 3. There was no statistically significant relationship between the variation in the anteroposterior and vertical measures and degree of basal arch width discrepancy.

Obesity has been implicated as a significant risk factor for multiple medical condition including hypertention, glucose intolerance, hyperlipidemia, hyperinsulinemia and fatty liver. Furthermore, obesity in childhood is believed to be a reliable predictor of a similar condition in adulthood. During the recent years, there has been a rapid rise in the incidence of childhood obesity in Korea due to increased dietary intake rich in caloric content. This study was undertaken to investigate the epidemiology and potential health complications of obesity observed in elmentary school students. A total of 3,103 children (1630 boys and 1,473 girls), ages ranging from 6 to 12, were studied with personal interview, physical examination, and laboratory evaluation. The results were as follows: 1) The prevalence of obesity was 13.44% with approximately equal distribution among boys (14.42%) and girls (12.36%). 2) The prevalence of childhood obesity in Seoul was significantly higher (18.62%) than that in Suwon (7.85%) and in Hongchon (6.02%). 3) A higher incidence of hypertension was dectected in obese subjects and this was more obvious in girls. 4) Hyperlipidemia and elevated Atherogenic Index were more frequently observed in obese group. 5) although fasting blood glucose levels were similar in both groups. AST and ALT abnormalities were much more prevalent in obese group. It is concluded that hypertension and other metabolic abnormalities are much more frequently observed in obese children and that our effects should be focused on the earliest dection, prevention and management of childhood obesity.

Dyke-Davidoff-Masson syndrome is a rare disorder which developed hemiatrophy of brain, enlargement of ventricles and prominent pneumatization of petrous pyramid of the temporal bone. It manifests hemiparesis, varying type seizure, and mental retardation. We experienced two cases of Dyke-avidoff-Masson Syndrome, in a 6/12 year-old boy and a 1, 10/12 year-old girl who were admitted to our department of pediatrics, because of convulsion and hemiparesis The brain CT scan showed marked dilatation of lateral ventricle, prominent sylvian fissure and cortical sulci. So we report two cases of Dyke-Davidoff-Masson syndrome with review of literature.

BACKGROUND: Diastolic dysfuction can be assessed by Doppler echocardiography of mitral inflow. Multiple factors including atrioventricular (AV) delay affect the mitral inflow Doppler indexes. This study was designed to assess the changes of mitral inflow patterns after successful radiofrequency catheter ablation (RFCA) of accessory pathway associated with a short AV interval during pre-excitation in patients with WPW syndrome. METHOD: Echocardiogram, ECG and BP were recorded before and after RFCA for treatment of accessory pathway in 15 patients with WPW syndrome (mean age : 39.7+/-14.6). Doppler indexes including E wave velocity and its velocity time integral (EVTI) ,A wave velocity and its VTI (AVTI), deceleration time (DT), isovolumic relaxation time (IVRT), atrial filling fraction (AFF)and total mitral inflow VTI were measured. RESULTS: 1) PR interval prolonged 94+/-18msec to 174+/-34msec (p<0.001) without significant increment of heart rate and blood pressure after successful RFCA. 2) E/A ratio decreased from 1.29+/-0.58 to 1.1+/-0.53 (<0.001) but E wave velocity, DT and IVRT were not changed significantly after RFCA. 3) A wave velocity and AFF was 55.8+/-17.4msec and 0.35+/-0.08 and increased to 61.8+/-19.9msec and 0.42+/-0.1, respectively after RFCA (p<0.05). 4) Total mitral inflow VTI was 13.6+/-3.5cm and 14.9+/-3.6cm before and after RFCA, respectively (p<0.05) CONCLUSION: These results suggested that normalization of the PR interval after RFCA in patients with WPW syndrome had beneficial hemodynamic effects on the stroke volume by changing mitral inflow Doppler indexes. Therefore, the effect of AV delay is an another parameter to consider when evaluating Doppler indexes of LV filling.

The majority of the cysts developed in pancreas are inflammatory pseudocyst but neoplastic cysts are rarely encountered Especially, mucinous cystadenoma which was begun and originated from epithelial cell of pancreatic duct is difficult to differentiate from pseudocysts by preoperative clinical, laboratory and radiologic findings. Mucinous cystadenoma has a malignant potentiality, so complete excision of cystadenoma is the treatment of choice. Recently, we experienced one case of mucionus cystadenoma in 37 year-old female, we report it with a review of the literature.

Eight neonates with transient tricuspid insufficiency are presented which was confirmed clinical and two dimensional echocardiographic assessment. We found that two dimensional Doppler echocardiography was very useful in the detection of transient tricuspid insufficiency during neonatal age as noninvasive method. Transient tricuspid insufficiency is a clinical disorder in the newborn period caused by myocardial dysfunction, secondary to asphyxia with or without hypoglycemia and associated with right ventricular overloading caused by pulmonary hypertention. The clinical diagnosis was based on a history of perinatal distress, distinctive murmur, ECG changes, biochemical abnormalities and myocardial imaging. 1) The sex ratio of TTI was 1:1. 2) The average gestational age was 34 weeks and mean body weight was 2.06 Kg, respectably. 3) Major symptoms were dyspnea, cyanosis, and tachypnea. 4) Tricuspid regurgitation was detected from the lst day to the 4th day of the life and was improved from the 7th day to the 30th day of the life. 5) The peak velocity through tricuspid valve ranged from the 2.7 m/sec to 4.0 m/sec and the estimated right ventricular pressure ranged from 39 mmHg to 74 mmHg. 6) Associated diseases were neonatal hyperbilirubinemia (100%), prematurity (87.5%), atrial right to left shunt (87.5%), patent ductus arteriosus (75%), hyaline membrane disease (25%), and transient tachypnea of newborn (12.5%).

The incidence of inadvertent posterior capsular rupture at each stage of planned ECCE and posterior chamber intraocular lens implantation was studied. From June 1985 to Dec. 1986, 133 cases of planned ECCE for posterior chamber intraocular lens implantation were performed. Posterior capsular rupture with or without vitreous loss was developed in 11 cases(8.2%) out of 133. The rupture occurred during nuclear expression in 2 cases(1.5%), during cortical clean-up in 6 cases(4.5%), during remval removal of anterior capsular flaps in 2 cases(1.5%), during posterior chamber intraocular lens implantation in 1 case(0.7%), but during posterior capsule polishing in nocase(0%). Vitreous loss was combined with posterior capsular rupture in 6 cases(4.5%), but the other 5 cases were not associated with vitreous loss(3.7%). After management of vitreous loss by automated anterior vitrectomy in 10 cases, anterior chamber intraocular lens was implanted. But in the other 1 cases with mid posterior capsular rupture without vitreous loss, anterior chamber intraocular lens was implanted without anterior vitrectomy. A final visual acuity of 0.5 or better by 2 months postoperatively was observed in 10 cases out of 11(91%).

PURPOSE: Persistent pulmonary hypertension (PPHN) of the newborn has been treated with some vasodilators including tolazoline. But these drugs have many side effects, especially systemic hypotension . To investigate the usefulness of the nitroglycerin as a specific vasodilator with few side effects, this study was done. METHODS: Nitroglycerin was administered within 1st one day after birth in 8 newborn infants who were diagnosed as PPHN by echocardiography. They were born at Il Sin hospital from March 1994 to March 1996. Nitroglycerin was started as 2microgram/kg/min and its maximum dose was 6microgram/kg/min. Muscle relaxants and inotropic drugs were used together in all cases. Arterial blood gas analysis, systemic blood pressure, heart rate, renal function and electrolyte were checked in all patients. Alveolar-arterial oxygen difference (AaDO2) and oxygenation index (OI) were measured. RESULTS: 6 cases (75%) survived but 2 cases expired due to air leak.1) Basal mean AaDO2 was 631.4+/-21.7mmHg. It decreased to 493.9+/-1453.1 mmHg at 10hr after loading infusion and to 373.6+/-217.7mmHg at 48hr (P<0.05). 2) Basal mean OI was 35.1+/-15.7 and it decreased significantly to 12.6+/-14.8 (P<0.05) at 10hr. 3) There was no significant hypotension in systolic, diastolic and mean blood pressure during treatment of nitroglycerin. 4) There was no significant change in renal function, serum electrolyte and heart rate during treatment of nitroglycerin. CONCLUSIONS: Nitroglycerin produced systemic venodilatation and pulmonary arterial dilatation at the dose that produce only minimal systemic arterial dilatation. Nitroglycerin is an effective and safe drug in the treatment of PPHN.
