  • Purpose: Plasma level of B-type natriuretic peptide (BNP), an emerging, sensitive, and specific biomarker of hemodynamically significant patent ductus arteriosus (PDA), rapidly decreases in infants receiving cyclooxygenase inhibitors for ductal closure. We investigated the usefulness of serial BNP measurement as a guide for individual identification of early constrictive responses to ibuprofen in preterm infants with symptomatic PDA (sPDA). Methods: Before March 2010, the standard course of pharmacological treatment was initiated with indomethacin (or ibuprofen) and routinely followed by 2 additional doses at intervals of 24 hours. After April 2010, individualized pharmacological treatment was used, starting with the first dose of ibuprofen and withholding additional ibuprofen doses if the BNP concentration was <600 pg/mL and clinical symptoms of PDA improved. Results: The BNP-guided group received significantly fewer doses of ibuprofen than the standard group did during the first course of treatment and the entire study period. The need for further doses of cyclooxygenase inhibitors and for surgical ligation was not significantly different between the 2 groups. No significant differences were seen in clinical outcomes and/or complications related to sPDA and/or pharmacological treatment. Conclusion: Individualized BNP-guided pharmacological treatment may be used clinically to avoid unnecessary doses of cyclooxygenase inhibitors without increasing the ductal closure failure and the short-term morbidity related to sPDA.

  • A 5-year-old female Cocker spaniel dog (body weight 7.0 kg) was presented with primary complaints of exercise intolerance and loud precordial thrill which was noticed since she was a puppy. Physical examination revealed a grade V/VI continuous murmur over the maximal point of the left basal area, bounding femoral pulse, but no differential cyanosis. Tall R waves were detected in electrocardiogram, suggesting left ventricular enlargement. Diagnostic imaging studies showed enlarged left ventricle, bulged descending aorta (dAo), markedly dilated right pulmonary artery, and continuous shunt flow between the dAo and main pulmonary artery. Based on these findings, the dog was diagnosed as left to right shunted patent ductus arteriosus (PDA). The patent ductus arteriosus was treated by lodging a PDA duct occluder via the transvenous approach. Clinical signs were markedly improved after the ductal occlusion, the shunt flow was mildly persistent. The case presented is the first case of PDA occluded by the PDA duct occluder via the transvenous approach in a small breed of dog. Although the residual shunt flow was mildly persisted, the dog was clinically normal without detectable murmurs.

  • Pyocele in infants is rarely described in the literature, but it is an emergent condition that requires rapid recognition and treatment to prevent testicular loss. If peritonitis due to gastrointestinal perforation occurs, abdominal contamination may spread through a patent processus vaginalis in an infant, which may lead to pyocele. We report the cases of three infants with scrotal pyocele due to the spread of infection or inflammatory material from the intraperitoneal cavity through a patent processus vaginalis. Two infants were surgically treated, while the other was treated with percutaneous aspiration and intravenous antibiotic administration. Although rare, pyocele should be considered in the differential diagnosis of acute scrotum in infants, especially in infants who previously had peritonitis due to gastrointestinal perforation.

  • A 50-year-old female was admitted to Pusan National University Hospital with complaints of fatigue and sweating. Echocardiography showed a small patent ductus arteriosus (PDA) and highly mobile vegetations on the aortic valve. Emergency operation was performed due to the high risk of embolization and severe aortic regurgitation. When the pulmonary artery opened, we found unexpected fresh vegetation. The tissue of the PDA was fragile and infected. We successfully removed the infected tissue, closed the PDA with a patch, and replaced the aortic valve with a mechanical prosthesis.

  • A Case of main pulmonary artery aneurysm in a 9-year-old boy with patent ductus arteriosus is presented. In this case presented with a huge mass density on the chest X-ray, radionuclide cardiac angiography showed a vascular lesion, which was confirmed as an aneurysm of the main pulmonary artery at roentgenologic angiogram. The aneurysm appeared following an episode of bacterial endocarditis and pulmonary hypertension. A successful aneurysmectomy with multiple ligation of ductus arteriosus was performed.

  • Objectives : We have examined and analyzed patents regarding acupuncture point stimulating methods in order to understand the stimulation technology and research trends of acupuncture points. Methods : We searched and analyzed the total of 135 on-line DB based patents under time limit of Dec, 2010. Results : According to the analyzed results, non-invasive method is used more than invasive method. Electric stimulation is used more than any other method, such as magnetic, ionic, laser, light, ultrasonic, water, Far IR and thermal stimulation. There are numbers of cases such as rejected during screening procedure, waived before the screening, of failed to renew its registrational status which outnumber those patents registered and maintained. Conclusions : These data suggest that we need to move away from using one side method such as non-invasive and electrical method. Thus follow-up service is recommended.

  • Since the first report of successful ligation of patent ductus arteriosus in 1939, it`s surgical intervention has become a routine and relatively safe procedure. During the past ten years from Aug. 1975 to Aug. 1985, 107 cases were operated on for a patent ductus arteriosus at the Department of thoracic and Cardiovascular Surgery, School of Medicine, Kyungpook National University. Clinical analysis of these cases was performed. Mean age at operation was 9.4 years, ranging from 20 months to 32 years. Sex ratio of female to male was 1.8;1. Most common symptoms were frequent respiratory infection, exertional dyspnea, and palpitation. Diagnosis was made by auscultation, 2 dimensional echocardiography, cardiac catheterization, and cineangiocardiography. A moderate to severe pulmonary hypertension was found in 42 cases [49.4%] in cardiac catheterization. Operative methods were multiple ligation of paten`. ductus arteriosus with or without Dacron or Teflon wrapping in 72 cases [68%], and division and suture in 34 cases [32%]. There were three operative deaths [2.8%]. The causes of death were hemorrhage from tearing of aorta, low cardiac output, and arrhythmia. All of these cases had moderate degree of pulmonary hypertension.
