    Notes: A new class of high thermal stability fused-ring guest chromophores intended for incorporation into highly stable host polyimides has been successfully developed. Thermal stabilities far in excess of 300 °C have been achieved for both the pure guest and the parent guest-host systems. dc-induced second harmonic generation measurements of the microscopic second order β of the guest chromophores in solution have been performed using an optical parametric generation technique. In the near-infrared region, values of the standard product μβ of order 103×10−48 esu have been observed. These values are in good agreement with quantum many-electron calculations.

    Notes: Abstract. We found that echocardiography in cases of left juxtaposed atrial appendage (JAA) consistently featured a malpositioned right atrial appendage, abnormal spatial orientation of the atrial septum, and posterior deviation of the septum secundum toward the left atrium. The qualitative displacement of the septum secundum together with the posterior and leftward displacement of the right atrial appendage (with respect to the great arteries) prompted us to pose questions concerning the morphogenesis of left JAA and the implications for surgery. The importance of precatheterization and preoperative recognition of left JAA in dextro-transposition of the great arteries by echocardiography cannot be overemphasized when planning a balloon atrial septostomy or a biventricular repair.

    Notes: Abstract. Constrictive pericarditis is rare in children. We report computed tomography (CT) and magnetic resonance imaging (MRI) findings in a 3-year-old girl. She had a swollen abdomen that increased in two months. CT and MRI showed a thickened pericardium (5.2 mm) without calcification. Both atria were enlarged and ventricles were relatively small. The engorged inferior vena cava had 2.8× the diameter of the descending aorta at the same level. Symptoms were dramatically improved after pericardiectomy. The histopathological features confirmed chronic pericarditis.

    Unusual form of total anomalous pulmonary venous connection with double drainage (1995)
    Springer
    Pediatric cardiology 16 (1995), S. 301-303

    ISSN: 1432-1971

    Topics: Medicine
    Notes: Abstract A patient with complex congenital heart disease was diagnosed by two-dimensional echocardiography. Total anomalous pulmonary venous connection (TAPVC) was suspected because of the results of two-dimensional echocardiography, but the exact anatomy was delineated by cineangiocardiography as an unusual form of TAPVC with double drainage or connections to the left superior vena cava at nearly the same level. The clinical implications and possible embryogenesis for such a condition are discussed.

    Aberrant left brachiocephalic vein: CT imaging findings and embryologic correlation (1999)

    Notes: Abstract. Computed tomography was utilized to evaluate aberrant left brachiocephalic vein (ALBCV), an infrequently discussed congenital vascular anomaly among Chinese people. Associated vascular variation and possible embryonic correlation are discussed. Since 1990, a total of 14 cases of ALBCV have been reported in patients receiving CT scan of chest, and was mainly an incidental diagnosis. One case was confirmed angiographically and two others were confirmed by magnetic resonance imaging. Emphasis was placed on the entry of the azygos vein into the superior vena cava (SVC), the length of the SVC, and the presence of other cardiovascular abnormalities. Of the 14 cases of ALBCV, the level of azygos vein entry was higher than the origin of the SVC in 7 cases: 4 were approximately the same level and 3 were lower. The average length of the SVC was approximately 5.6 cm shorter than that of the general population, which is approximately 7.0 cm. Three cases had associated vascular anomaly. Most cases of ALBCV had azygos vein drainage level higher than or equal to the origin of the SVC. Right-sided aorta is one of the causes giving rise to the ALBCV during embryonic development. The CT scan remains a definitive diagnostic modality for ALBCV.

    Congenital bilateral agenesis of diaphragm: report of a case (1997)

    Notes: Abstract Bilateral agenesis of the diaphragm is a rare, life-threatening malformation. Infants with this defect rarely survive to have surgical intervention. We report a 32-week premature female infant who was born to a 36-year-old mother via vaginal delivery. The pregnancy course was complicated by hypertension and polyhydramnios. Cytogenetic study showed a normal 46 XX female karyotype. She had cyanosis, respiratory distress and scaphoid abdomen at birth. A roentgenograph confirmed the diagnosis of diaphragmatic hernia. Surgery was performed at 21 h of age. Bilateral agenesis of diaphragm, herniation of abdominal organs and oesophagus and pulmonary hypoplasia were noted. Furthermore, stomach and spleen were adherent to the mediastinum and vertebrae. The patient developed hypotension and persistent hypoxaemia and expired at age of 26 h. Autopsy revealed bilateral agenesis of diaphragm, hypoplasia of lungs, and pancreas fibrosis with mild hypoplasia of islets of Langerhans. Conclusion Bilateral agenesis of diaphragm associated with pancreas fibrosis is a rare entity, and its clinical significance needs further investigation.

    Notes: Abstract Total anomalous pulmonary venous connection (TAPVC) is an uncommon congenital anomaly in which the anatomical presentations vary widely among patients. We hereby present two newborns with TAPVC associated with asplenia syndrome; both had severe esophageal varices due to infradiaphragmatic pulmonary venous drainage. Ultrafast computed tomography (CT) scanning was superior to color Doppler echocardiography and cardiac catheterization as it provided a detailed portrait of the pulmonary drainage. The remarkable radiographic manifestations are presented.

    Notes: A multiple component inspection path planning problem (MCIPP) can be formulated as an optimisation problem, referred to as a non-deterministic polynomial complete problem (NP). An MCIPP consists of testing points, which will be visited by a CMM probe only once, and dummy points which are set to avoid collision and may be visited by a CMM probe more than once. This paper considers the application of genetic algorithms (GAs) acting as optimisers for optimal inspection path planning systems. The paper explores the techniques used in the GA optimal inspection path planning system. The paper also discusses the comparison of integer programming models and genetic models.
