BACKGROUND AND PURPOSE: Laser induced prostatectomy(LIP) has recently been considered as safe alternative to conventional transurethral resection of the prostate(TURP) in the surgical treatment of BPH. However, the value of LIP remains incompletely defined. We herein have performed a prospective study to compare TURP and LIP in treatment efficacy, safety and costs to define the value of LIP. MATERIALS AND METHODS: 113 patients with BPH who were candidates of TURP were randomized to undergo TURP or LIP and were adequately followed up for more than 1 year. There were no significant differences in preoperative clinical characteristics between 55 patients who underwent TURP and 58 patients who underwent LIP. For the LIP procedure, Nd:YAG was used in 42 patients and diode laser in 16 patients, respectively. 37 patients were treated by contact LIP only, and 21 with hybrid procedures of contact LIP and noncontact LIP using side firing laser fiber or interstitial laser fiber. Seven patients underwent LIP under local anesthesia at the outpatient department. RESULTS: International prostate symptom score(IPSS) and peak urinary flow rate(Qmax) were significantly improved at 3 months, 6 months, and 1 year after LIP as well as after TURP. There were no significant difference between TURP group(85.4%) and LIP group(87.9%) in treatment success rate as defined by improvement of IPSS and Qmax as well as patient's content for the surgical outcome. Nine(16.4%) and two(3.6%) of the patients who underwent TURP and none of the patients who LIP underwent developed ignificant bleeding and electrolyte imbalance, respectively. There were no significant difference in postoperative incidence of retrograde ejaculation, infection and urethral stricture between the two groups. Compared to TURP, the LIP procedure required significantly shorter hospitalization(6.8 vs 4.5 days) and catheterization(4.1 vs 2.6 days, all p<0.0l). There was no significant difference in total treatment cost between the two groups. CONCLUSIONS: LIP may be comparable to TURP in terms of short term treatment efficacy and cost effectiveness. LIP may be better than TURP in terms of safety and shortened hospitalization and catheterization. Further studies are necessary on long-term outcomes of LIP."

The incidence of ectopic pregnancy has been increasing for many years and ectopic pregnancy is still a leading cause of maternal death although its mortality is reduced significantly with improved early diagnosis and treatment. Intraligamentous pregnancy, a subset of ectopic pregnancy, is one of the most unusual accident so that the diagnosis of intraligamentous pregnancy is hardly ever made prior to laparotomy. We experienced intraligamentous pregnancy with hemoperitoneum. So we presented a case with brief review of literature.

Acute giant coronary aneurysm after Kawasaki disease (KD) is a catastrophic complication that can be fatal and very difficult to manage. However, no fixed consensus has been reached for the management of super-giant coronary aneurysms in the acute setting. Here, we report the successful management of young children with super-giant coronary aneurysms after KD. Based on our experience, hemodynamic stabilization to prevent further coronary dilation or rupture and strict anticoagulation to avoid thrombus formation are mandatory in the management of this condition.

PURPOSE: The use of implantable cardioverter defibrillators (ICDs) to prevent sudden cardiac death is increasing in children and adolescents. This study investigated the use of ICDs in children with congenital heart disease. METHODS: This retrospective study was conducted on the clinical characteristics and effectiveness of ICD implantation at the department of pediatrics of a single tertiary center between 2007 and 2011. RESULTS: Fifteen patients underwent ICD implantation. Their mean age at the time of implantation was 14.5+/-5.4 years (range, 2 to 22 years). The follow-up duration was 28.9+/-20.4 months. The cause of ICD implantation was cardiac arrest in 7, sustained ventricular tachycardia in 6, and syncope in 2 patients. The underlying disorders were as follows: ionic channelopathy in 6 patients (long QT type 3 in 4, catecholaminergic polymorphic ventricular tachycardia [CPVT] in 1, and J wave syndrome in 1), cardiomyopathy in 5 patients, and postoperative congenital heart disease in 4 patients. ICD coils were implanted in the pericardial space in 2 children (ages 2 and 6 years). Five patients received appropriate ICD shock therapy, and 2 patients received inappropriate shocks due to supraventricular tachycardia. During follow-up, 2 patients required lead dysfunction-related revision. One patient with CPVT suffered from an ICD storm that was resolved using sympathetic denervation surgery. CONCLUSION: The overall ICD outcome was acceptable in most pediatric patients. Early diagnosis and timely ICD implantation are recommended for preventing sudden death in high-risk children and patients with congenital heart disease.

Since the first descriptions of Brugada as a new clinical entity defined by sudden cardiac death in patients with typical electrocardiogram (ECG) patterns, Brugada syndrome (BS) has been increasingly diagnosed. This syndrome is known as a disease that is inherited via an autosomal dominant trait, and the SCN5A mutation has been found in 20-25% of BS patients. Because BS primarily manifests in adulthood, little information is available on BS during childhood. Although there have been several reports on adult BS in Korea, pediatric BS has not been reported. Herein, we report on childhood BS in two families. One infantile BS patient and his family had a novel SCN5A mutation (c.4035G>T, p.W1345C, heterozygote) in domain III of the sodium channel.

BACKGROUND AND OBJECTIVES: We hypothesized that fetal echocardiography (echoCG) is an accurate diagnostic tool reflecting well postnatal echoCG findings and outcomes. SUBJECTS AND METHODS: We reviewed the medical records of 290 pregnant women, including 313 fetuses, who were examined by fetal echoCG at the Seoul National University Children's Hospital from January 2008 through April 2011. RESULTS: The mean gestational age at diagnosis was 26.2+/-5.2 weeks. The mean age of mothers at diagnosis was 31.7+/-3.8 years. We identified indications for fetal echoCG in 279 cases. The most common indication was abnormal cardiac findings in obstetrical screening sonography (52.0%). Among the 313 echoCG results, 127 (40.6%) were normal, 13 (4.2%) were minor abnormalities, 35 (11.2%) were simple cardiac anomalies, 50 (16.0%) were moderate cardiac anomalies, 60 (19.2%) were complex cardiac anomalies, 16 (5.1%) were arrhythmias, and 12 (3.8%) were twin-to-twin transfusion syndrome. The most common congenital heart disease was tetralogy of Fallot (23 fetuses, 15.9%). One hundred forty-eight neonates were examined by echoCG. We analyzed differences between fetal echoCG and postnatal echoCG. In 131 (88.5%) cases, there was no difference; in 15 (10.1%), there were minor differences; and in only 2 (1.4%) cases, there were major differences. CONCLUSION: There is a recent increase in abnormal cardiac findings of obstetric ultrasonography screenings that indicate fetal echoCG. Fetal echoCG is still a good, accurate diagnostic method for congenital heart disease.

BACKGROUND AND OBJECTIVES: Vascular rings refer to anomalies of the great arteries that cause respiratory or feeding problems. The purpose of this study was to analyze a series of patients with vascular rings and evaluate associated risk factors for mortality. SUBJECTS AND METHODS: A retrospective review of all patients identified with vascular rings between 1997 and 2010 in the Seoul National University Children's Hospital. RESULTS: Thirty-five patients were diagnosed with vascular rings (median age at diagnosis, 7 months). The vascular rings of 32 patients were confirmed by cardiac computed tomography or magnetic resonance imaging. The types of vascular rings were: a double aortic arch in ten patients, a right aortic arch with persistent left ligamentum arteriosum in seven, an aberrant subclavian artery in seven, a pulmonary sling in eight, and others types in three patients. Eleven patients were asymptomatic. Gastrointestinal and respiratory symptoms were seen in ten and sixteen patients, respectively. Associated cardiovascular anomalies were present in fifteen patients. Twenty patients with definite symptoms underwent surgical treatment. The median interval between diagnosis and operation was 6 days. Four patients eventually died; three deaths were associated with complex heart diseases, and one had pulmonary artery sling with severe tracheal stenosis. Only the presence of a complex heart disease significantly influenced mortality (p=0.002). CONCLUSION: Vascular rings include several types of anomalies, each with a different prognosis and symptoms. The presence of a complex heart disease was significantly associated with mortality. Early diagnosis and timely surgery in symptomatic patients are essential.

BACKGROUND AND OBJECTIVES: This study aimed to evaluate the usefulness of cardiopulmonary exercise test (CPET) in children with various congenital heart diseases (CHDs). SUBJECTS AND METHODS: Forty-eight children and adolescents (18 girls and 30 boys; mean+/-SD age, 12.6+/-0.5 years) with CHD who had undergone corrective surgery performed CPET using a programmable treadmill. The participants were divided into 4 groups based on the surgery performed: Fontan operation (12 patients), total correction for tetralogy of Fallot (13 patients), repair for coarctation of aorta (11 patients), and corrective surgery for simple CHDs (12 patients). Patients with simple CHDs who had undergone an early surgery were selected as controls. RESULTS: Progressive exercise time was the longest in the simple CHD group than in the other groups (10.6+/-2 versus 8.2-8.7 min, p=0.122). Absolute and predicted values of mean peak oxygen consumption were the lowest in the Fontan operation group (p=0.220 and 0.091, respectively). The coarctation of aorta group exhibited a prominent blood pressure response, that is, an elevation in the systolic blood pressure relative to that in the other groups at rest (131.7+/-18.8 versus 114.4-121.3 mmHg) and at peak exercise (196.5+/-41.5 versus 146.8-184.3 mmHg). CONCLUSION: CPET can be a useful tool to clarify the exercise capacity and reflect the hemodynamic status of patients who have undergone surgery for various CHDs and other heart diseases.

Takayasu arteritis is a chronic inflammatory disease of unknown etiology primarily affecting the aorta and its major branches and usually occurring in the second or third decade of life. Here, we report a case of Takayasu arteritis in a 10-month-old patient. The infant presented with signs of congestive heart failure and severe aortic regurgitation. Echocardiography and computed tomography angiography showed an abnormally dilated thoracic and abdominal aorta. The infant was initially treated with prednisolone, followed by commissuroplasty of the aortic valve but neither approach ameliorated the heart failure. The patient was eventually treated with a mechanical aortic valve replacement surgery at the age of 12 months, and her condition stabilized. Although unusual, this case indicates that the diagnosis of Takayasu arteritis should be considered in children with unexplained systemic symptoms, aortic valve regurgitation, and heart failure. Because severe aortic regurgitation may be a fatal complication of Takayasu arteritis, early aortic valve replacement surgery should be considered, even in very young children.
