Abstract

The FT-IR spectra of a thin layer of pure 4-chloro-2′-hydroxy-4′-pentyloxyazobenzene (CHPAB) were studied as a function of temperature. A detailed analysis of the intensity variations was performed by a method based on principal component analysis (PCA). It was shown that the phase transition temperatures obtained by means of PCA and those determined by differential scanning calorimetry (DSC), the most widely used technique in the field, were nearly identical. The PCA results revealed that the transition from solid to a liquid crystalline (LC) phase (smectic A) is more drastic phase transition in terms of infrared absorption changes. The nematic to isotropic phase transition is much less infrared sensitive. Very much smaller absorption changes are associated with the transition between the smectic and nematic mesophases. The pattern of the intensity changes strictly is correlated with the orientation of the CHPAB molecules towards the surface windows due to the surface-induced homeotropic alignment of LC molecules. The important role of hydrogen bonding interaction on the observed transition is disclosed.

Abstract

The authors present the results of surgical treatment obtained in 288 children with tetralogy of Fallot. In 127 children palliative procedures (pulmonary-systemic anastomoses) were employed, whereas 161 patients were subjected to total surgical corrections of the defect, performed in cardiopulmonary bypass. In 127 (79%) belonging to the latter group the correction was a single stage procedure, and in 34 (21%), it followed pulmonary-systemic anastomoses. Perioperative mortality rate in children subjected to single stage procedures was 12%, being lightly lower than the rate observed in patients subjected to two stage procedures. The analysis of operative results corrected for age revealed a higher mortality rate in children operated when less then two years of age (17%) in comparison to older patients (11%).

Abstract

We present a review of our recent experience of operating on infants below 2500 g suffering from congenital heart disease. A retrospective review was performed in 73 children who had undergone cardiac operations at our institution from 1990 to 1999. There were 43 (59%) females and 30 (41%) males; the mean age at operation was 28 days (range 4 to 92). The mean gestational age was 34.7 weeks (range 24 to 41), mean birth weight--1899 g (range 700 to 2450) and mean weight at operation--2013 g (range 640 to 2500). Cardiac diagnoses included patent ductus arteriosus (PDA) (N = 21, 28.7%), ventricular septal defect (VSD) (N = 9, 12.3%), transposition of great arteries (TGA) (N = 10, 13.7%), tetralogy of Fallot (TOF) (N = 7, 9.6%), double-outlet right ventricle (DORV) (N = 4, 5.5%), truncus arteriosus communis (TAC) (N = 4, 5.5%), hypoplastic left heart syndrome (HLHS) (N = 4, 5.5%), coarctation of aorta (CoAo) (N = 6, 8.2%), total anomalous pulmonary venous return (TAPVR) (N = 2, 2.7%), aortic stenosis (AoVS) (N = 3, 4.1%), interrupted aortic arch (IAA) (N = 1, 1.4%), pulmonary atresia (PA) (N = 1, 1.4%) and common atrioventricular canal (CAVC) (N = 1, 1.4%). Hospital mortality was 16.4%. There were 6 early deaths (8.2%) and 6 late deaths (8.2%). A higher mortality rate was noted in premature children and in children who had undergone palliative procedures. At a 1-116-month follow-up (mean 39 months), of 57 (93.4%) patients, 46 (80.7%) were in NYHA class I and 11 (19.3%) in NYHA class II. In conclusion the authors believe that early intervention can be performed in infants below 2500 g, and the associated mortality and morbidity rates are low.
