The purpose of this study is to evaluate the ventricular conduction abnormalities, especially RBBB, observed electrocardiographically after surgical closure of VSD. The present study population consists of 92 patients with VSD who were surgically corrected at the Hanyang University Hospital during 6 years period from Jan. 1985 to Dec. 1990. We reviewed their clinical records including surgical notes and EKG findings before and after operations. The results of the study were as follows: 1) Male to female ratio was 1.1:1 (48:44) 2) Out of a total of 92 cases of VSD, 65cases(70.7%)were perimembranous type and 27 cases (29.3%)were subarterial type. 3) The normal preoperative EKG findings were seen in 22 patients, LVH in 21 patients, BUH in 47patients, and RVH in 3 patiens. 4) A transatrial approach was performed in 55 cases, right ventriculotomy with or without resection of muscles in right ventricle in 13 cases, and pulmonary arteriotomy alone in 24 cases. 5) The right bundle branch block after operation developed in 33 patients out of the 65 patinets with perimembranous defect and 5 patients out of the 27 patients with subarterial defects. Postoperative RBBB developed more frequently in perimembranous defect than in subarterial defect. 6) Postoperative RBBB occured in 31.8% of the patients with normal preoperative EKG findings, 23.8% with preoperative LVH, 52.1% with BVH and 66.7% with RVH. Postoperative RBBB was more frequently observed in the patients group with preoperative BVH or RVH than the patients with normal or LVH. 7) Postoperative RBBB was observed in 84.6% after right wentriculotomy, in 43.6% after right atriotomy and in 12.5% with pulmonary arteriotomy alone.

PURPOSE: Neonatal lupus is characterized by congenital complete heart block(CCHB), cutaneous rash, and laboratory abnormalities in infants born to mothers with systemic lupus erythematosus(SLE). This study aims to examine the incidence of CCHB and clinical outcome in neonates born to mothers with SLE. METHODS: The study group consisted of 49 neonates, born from 57 pregnancies of 55 women with SLE, diagnosed at Hanyang University Hospital for the period between January 1997 and January 2005. Clinical and laboratory data were retrospectively identified from medical record. RESULTS: There were 5(8.8 percent) spontaneous abortions and one(1.8 percent) still births among 57 pregnancies of 55 mothers. Of 49 live births, 15(26.3 percent) were premature and eight(12.3 percent) were small for their gestational age. There was one(1.8 percent) CCHB suspected during pregnancy on fetal echocardiograpy in a fetus of mother with systemic lupus erythematosus and the fetus was not born by artificial abortion because of mother. There was no CCHB among EKG findings of 49 newborns. Laboratory testing showed hematologic abnormalities among 25.6 percent(10/39) of the babies. 5.1 percent(2/39) and 7.7 percent(3/39) of them were diagnosed as neutropenia, and thrombocytopenia was seen respectively. Anti-SSA(Ro) and antiphospholipid antibodies were predictive factors for prematurity(P=0.003, P=0.049). Anticardiolipin antibodies were predictive factors for ventilatory care(P=0.018). CONCLUSION: The incidence of CCHB among neonates born to mothers with SLE, which was measured in this study, was lower than that in earlier studies. A high incidence of hematologic abnormalities was found in our study. It is suggested that careful examination should be made of skin for the diagnosis of neonatal lupus.

OBJECTIVES: We retrospectively evaluated the impact of mandibular third molars on the occurrence of angle and condyle fractures. MATERIALS AND METHODS: This was a retrospective investigation using patient records and radiographs. The sample set consisted of 440 patients with mandibular fractures. Eruption space, depth and angulation of the third molar were measured. RESULTS: Of the 144 angle fracture patients, 130 patients had third molars and 14 patients did not. The ratio of angle fractures when a third molar was present (1.26 : 1) was greater than when no third molar was present (0.19 : 1; odds ratio, 6.58; P<0.001). Of the 141 condyle fractures patients, the third molar was present in 84 patients and absent in 57 patients. The ratio of condyle fractures when a third molar was present (0.56 : 1) was lower than when no third molar was present (1.90 : 1; odds ratio, 0.30; P<0.001). CONCLUSION: The increased ratio of angle fractures with third molars and the ratio of condyle fractures without a third molar were statistically significant. The occurrence of angle and condyle fractures was more affected by the continuity of the cortical bone at the angle than by the depth of a third molar. These results demonstrate that a third molar can be a determining factor in angle and condyle fractures.

PURPOSE: Chest pain in the pediatric population is not rare and mostly benign. Causes of chest pain are diverse, and differential diagnosis is not easy. Chest pain in children is less likely to be cardiac in origin. Furthermore, chest pain in the pediatric population is rarely associated with life-threatening disease. This study was designed to evaluate children with chest pain and the usefulness of several diagnostic examinations. METHODS: Between March 2001 and August 2002, 33 patients(15 boys and 18 girls, aged four to 15 years) presented with chronic chest pain. The records of these patients were reviewed. Chest radiography and electrocardiogram were performed in all patients. Cardiologic and gastrointestinal evaluations were carried out when considered necessary. RESULTS: Chest pain was most common in the age group of 10 to 12 years old, and the four to six years old group. The most common diagnostic findings of chest pain were idiopathic(15 cases, 45.5 %), heart disease(9 cases, 27.3%), upper gastrointestinal disease(6 cases, 18.2%), respiratory disease (2 cases, 6%) and trauma(1 case, 3%). In children with abnormal results of cardiologic evaluation, these findings are not major etiologic categories of chest pain. Through history taking and physical examinations, six cases were evaluated concerning gastrointestinal disease and all of them showed gastrointestinal diseases(esophagitis, gastroesophageal reflux disease, nodular gastritis and chronic superficial gastritis). CONCLUSIONS: Chest pain is usually benign in children but the possibility of cardiovascular or gastrointestinal disease is considered. Careful history taking, physical examination and proper clinical examinations are usually required to find out the rare life-threatening causes of chest pain.

The posttraumatic complications of jaw fractures related to jaw function and facial deformity include nonunion, malunion, malocclusion, temporomandibular joint dysfunction and facial asymmetry. This report presents cases referred to our department for revision of malunion and malocclusion following inadequate reduction of jaw fractures. Three patients with posttraumatic malocclusions caused by malunion were treated with a LeFort I osteotomy in one case and re-fracture in two cases. All of the patients exhibited stable results without further complications (e.g., malunion or malocclusion). Accurate preoperative diagnosis and proper anatomical reduction of the fracture segments are essential to preventing post-surgical malunion and malocclusion.
