Bilateral Synchronous Testicular Germ Cell Tumors in Children: Case Report and Review of the Literature.

Bilateral testicular tumors are very rare in pediatric patients and only a few case reports have been reported. These patients have a high risk of sterility due to bilateral orchiectomy and subsequent gonadotoxic treatments. Therefore, if possible, testis-sparing surgery should be performed in patients with benign masses and testicular tissue preservation may be recommended in order to maintain fertility in later life.

Spent embryo culture media from all patients were collected after single embryo transfer on day 3 (n = 40).

Plasma microRNA profiling of children with idiopathic dilated cardiomyopathy.

Context: Dilated cardiomyopathy (DCM) is the most common cardiomyopathy in children. MicroRNAs (miRNA) are small RNAs which have regulatory functions in many biological processes.

Follow-up of P dispersion after transcatheter closure of an atrial septal defect in children.

Objectives: To determine in paediatric patients with atrial septal defects whether differences in P wave dispersion occurred with transcatheter closures using the Amplatzer septal occluder.

Method: A total of 31 children who had undergone transcatheter closures were evaluated. P maximum, P minimum, and P dispersion were measured with 12-lead surface electrocardiography, before the procedure and one week, one month, three months, six months and one year following the procedure.

Transjugular closure of a two-hole atrial septal defect in a child with iliac vein thrombosis.

The internal jugular vein is not a typical vascular access line during the percutaneous closure of an atrial septal defect. We report the closure of a double atrial septal defect with a single device, using a transjugular venous approach, in a child with an inferior vena cava obstructed by a thrombosis due to previous cardiac catheterization. That the transjugular venous approach can be used as a possible alternative during the transcatheter closure of an atrial septal defect in children, when the inferior vena cava access is not possible.

Intracardiac thrombus in children with dilated cardiomyopathy.

Objectives: The risk of fatal pulmonary and systemic thromboembolism is high in patients with dilated cardiomyopathy with cardiac thrombus. This study was planned to reveal the efficacy of antiaggregant therapy in patients with low left ventricular systolic ejection fraction (LVEF).

Study Design: The present study retrospectively reviewed the files of 83 cases (42 males, 41 females) with dilated cardiomyopathy who were followed between June 2004 and December 2011.

Bioabsorbable atrial septal occluder for percutaneous closure of atrial septal defect in children.

The BioSTAR bioabsorbable septal repair implant is a new transcatheter secundum atrial septal defect occlusion device that is absorbed and replaced by healthy native tissue. This retrospective analysis was designed to determine the most significant factors for its successful use in children. From October 2009 through December 2010, 33 children underwent catheterization to close secundum atrial septal defects by means of the BioSTAR.

Patients with atrial septal defect have an increased risk for atrial fibrillation. Increased P-wave dispersion predicts the development of atrial fibrillation. The aim of this study was to determine difference in P dispersion between transcatheter closure with Amplatzer septal occluder and surgical closure in childhood.

Double outlet right ventricle with giant pulmonary artery aneurysm and severe aortic coarctation: diagnosis with multislice CT.

Complex cardiovascular pathologies in the pediatric population are usually evaluated with echocardiography and catheter angiography as initial and advanced imaging of choice, respectively. Echocardiography may pose some difficulties in the diagnosis of complex cardiovascular pathologies. Due to short acquisition times, detailed imaging by the use of post-processing techniques, reduced radiation exposure compared to catheter angiography, and additional information obtained on lung parenchyma, multi-slice computed tomography (CT) is the advanced imaging method of choice in selected cases.

Congenital pulmonary venous stenosis combined with valvular aortic stenosis: a very rare case.

Congenital pulmonary venous stenosis is a rare condition leads to progressive pulmonary hypertension and heart failure. It may be isolated or associated with other cardiac malformations. The condition ranges from hypoplasia of individual pulmonary veins to constriction of the intima of the venoatrial junction.

Horseshoe lung associated with rare bilateral variant of scimitar syndrome: demonstration by 64-slice MDCT angiography.

Scimitar syndrome with bilateral abnormal venous drainage and horseshoe lung is extremely rare. These rare complex anomalies were diagnosed in a 5-year-old boy by 64-slice multidetector CT (MDCT). This technique provides high-quality visualization of vascular, bronchial and parenchymal structures in a single session, such that no further invasive techniques are required.
