Effect of Piracetam and Iron Treatment on Heart Rate Variability in Patients With Breath-Holding Spell.

BACKGROUND: Breath-holding spells are a benign condition primarily seen in 3% to 5% of healthy children aged between six months and five years. Although no specific treatment is recommended due to its benign nature, iron and piracetam are used in severe or recurrent cases. We planned to compare the heart rate variability (HRV) before and after treatment with 24-hour Holter monitoring in patients receiving iron and piracetam treatment and investigate the treatment's effectiveness. METHODS: Twenty-five patients who applied to the outpatient clinic between 2013 and 2015 due to breath-holding spells were included in the study. The patients who received piracetam and iron therapy and underwent 24-hour rhythm Holter monitoring were evaluated retrospectively. RESULTS: Fourteen (56%) of these patients were evaluated as having cyanotic-type and 11 (44%) patients were assessed as having pale-type breath-holding spells. A significant difference was found only between hourly peak heart rate and total power in the group receiving iron treatment. Significant differences were also found among the minimum heart rate, mean heart rate, the standard deviation of RR intervals, the mean square root of the sum of the squares of their difference between adjacent RR intervals, spectpow, and low frequency before and after the treatment in the patients who started piracetam treatment (P < 0.05). CONCLUSIONS: Our study is critical as it is the first to investigate the effects of treatment options on various HRV in patients with breath-holding spells. There were statistically significant changes in HRV parameters in patients receiving piracetam, and the number of attacks decreased significantly. Piracetam treatment contributes positively to the breath-holding spell with regard to efficacy and HRV, therefore it can be used to treat breath-holding spells.

Fechamento transcateter de fístula de artéria coronária com dispositivo Amplatzer Piccolo™ / Transcatheter closure of coronary artery fistula with Amplatzer Piccolo™ device

As fístulas das artérias coronárias são anomalias congênitas raras e caracterizam uma comunicação anormal entre as artérias coronárias e as câmaras cardíacas ou grandes vasos. Muitos dispositivos que incluem vários coils, plugues vasculares, oclusores e stents recobertos têm sido usados no fechamento transcateter de fístulas de artérias coronárias. Neste relato, realizamos com sucesso o fechamento de uma fístula de artéria coronária, entre a artéria descendente anterior e o ápice do ventrículo direito, usando o dispositivo Amplatzer PiccoloTM, anteriormente chamado de tamanho adicional do AmplatzerTM Duct Occluder. Em nossa opinião, o dispositivo Amplatzer PiccoloTM é adequado para oclusão transcateter de fístula da artéria coronária, podendo ser usado no lugar de plugues vasculares.

Coronary artery fistulas are rare congenital anomalies and characterize an abnormal communication between coronary arteries and cardiac chambers or major arteries. Many devices, including various coils, vascular plugs, occluders, and cover stent, have been used in transcatheter closure of coronary artery fistulas. In this report we successfully closed coronary artery fistula, between left anterior descending artery and right ventricle apex, by using Amplatzer PiccoloTM device, formerly called as AmplatzerTM Duct Occluder additional size. In our opinion, Amplatzer PiccoloTM device is suitable for transcatheter occlusion of coronary artery fistula and can be used instead of vascular plugs.

Serum Nickel and Titanium Levels after Transcatheter Closure of Atrial Septal Defects with Amplatzer Septal Occluder.

INTRODUCTION: There is a concern about release of nickel and titanium after implantation of nitinol-containing devices. OBJECTIVE: To evaluate serum nickel and titanium release after implantation of Amplatzer occluder. MATERIALS AND METHODS: In 38 pediatric patients with no history of nickel sensitivity, blood samples were drawn 24 hours before and 24 hours, 1, 3, 6, and 12 months after implantation. Nickel and titanium concentrations were measured by atomic absorption spectrophotometry. RESULTS: The median serum nickel level which was 0.44 ng/mL before the implantation increased to 1.01 ng/mL 24 hours after implantation and 1.72 ng/mL one month after implantation. The maximum level was detected 3 months after implantation, with a median level of 1.96 ng/mL. During follow-up, the nickel levels decreased to those measured before implantation. Serum nickel levels at the 24th hour, 1st month, and 3rd month following implantation were found to have increased significantly. No patients showed a detectable serum titanium level. DISCUSSION: This is the first study that evaluated both serum nickel and titanium release after implantation of the Amplatzer occluder. Our study shows that nickel is released from the device in the first few months after implantation. Therefore, in patients with nickel allergy, other devices may be considered.

Huge Left Atrial Pseudoaneurysm in a 5-Month-Old Baby Presented with Supraventricular Tachycardia.

UNLABELLED: Cardiac pseudoaneurysm is an extremely rare condition in children. It can be congenital or acquired and has been primarily described in the left side of the heart. The congenital form of pseudoaneurysm is thought to be related to muscular dysplasia of the muscular layer of the heart. The acquired form is related to myocardial infarction, infective endocarditis or chest trauma. In this report we described a 5-month-old baby with left atrial pseudoaneurysm who was referred to our hospital due to tachycardia and hemodynamic instability. After diagnosis of left atrial pseudoaneurysm, aneurysmectomy was performed and the left atrial wall was successfully repaired by surgery three days after admission. In conclusion, due to life threatening complications such as dissection, arrhythmias, compression of aneurysm and tromboembolic complications, pseudoaneurysm should be treated by surgery. KEY WORDS: Chest trauma; Left atrial pseudoaneurysm; Supraventricular arrhythmias.

Perioperative management of a levoatrial cardinal vein in the absence of the brachiocephalic vein.

Levoatrial cardinal vein is a rare congenital anomaly of the systemic veins. It is commonly associated with left-sided obstructive conditions such as aortic atresia, mitral atresia, and cor triatriatum. We report the case of a 14-year-old boy who was undergoing surgery for correction of a secundum atrial septal defect. Intraoperatively, we discovered that he had a levoatrial cardinal vein and no brachiocephalic vein. However, collateral vessels provided adequate flow to the right atrium, and the patient's left-sided venous pressure was not excessive, so we ligated the levoatrial cardinal vein and directly repaired the septal defect. Postoperatively, the left venous drainage was satisfactory and the patient was asymptomatic. In addition to our patient's case, we discuss the embryology, diagnosis, and treatment of levoatrial cardinal vein.

An unexpected cause of respiratory distress and cyanosis: cardiac inflammatory myofibroblastic tumor.

Inflammatory myofibroblastic tumor is an uncommon spindle cell tumor, occurring mainly in children and young adults. It is an extremely rare cardiac tumor especially patients under 1 year. Although it is benign, the tumor may be very aggressive locally. The diagnosis of this unusual pediatric cardiac tumor without pathologic specimens is difficult. We report a rare case of inflammatory myofibroblastic tumors of the right ventricle in a 7-month-old girl presenting with respiratory distress and cyanosis.

Malignant infantile osteopetrosis: a rare cause of neonatal hypocalcemia.

Malignant infantile osteopetrosis is a rare autosomal recessive disorder characterized by presentation in the first few months of life with manifestations relating to an underlying defect in osteoclastic bone resorption. This report describes a 10 day-old boy in whom neonatal hypocalcemia was present and whose brother had died with the diagnosis of osteopetrosis.
