    • INTRODUCTION: Dilatation of intercellular spaces of the esophageal squamous epithelium has been suggested as a marker of early acid reflux-induced damage. This change is a potentially useful addition to histomorphological changes that represent so called minimal endoscopic lesions. We have assessed dilatation of intercellular spaces with regard to: (1) interobserver variability, and (2) whether the incidence of this varies between 'red streaks' and the adjacent normal looking squamous epithelium. METHODS: Esophageal biopsies from 44 patients with chronic gastro-esophageal reflux (GERD) were evaluated. At endoscopy, these patients had one or more red streaks on the tops of the mucosal folds in the distal esophagus. Biopsies were taken from the red streaks and from the normal-appearing mucosa 1 cm lateral to the red streaks. Biopsies were assessed in a blinded fashion by two independent pathologists (MV & RF). Criteria for assessing intercellular space dilatation were evaluated and agreed on prior to the study. RESULTS: Good interobserver agreement was recorded (kappa = 0.82 at the streaks and 0.77 for the control tissues) for absence/presence of intercellular space dilatation. Red streak and control biopsies differed significantly (p = 0.0001), with respect to presence of dilated intercellular spaces, with 90.5 % of the former demonstrating this as present compared to 56.1% in the controls. CONCLUSION: This study supports the concept that esophageal mucosal minimal changes due to reflux is localised and that dilatation of intercellular spaces is an early sign of reflux-induced epithelial damage. The low interobserver variability in the assessment of intercellular space dilatation suggests that this may be a useful variable for assessment of early signs of acid-reflux induced damage to the squamous epithelium of the esophagus by use of light microscopy.

  • The outcome of children born with pulmonary atresia and intact ventricular septum in Sweden from 1980 to 1999.

    • OBJECTIVE: To study the outcome of all children born with pulmonary atresia and intact ventricular septum in Sweden between 1980 and 1999. DESIGN: Retrospective study of medical records with review of the initial, preoperative angiocardiographic and echocardiographic examinations. RESULTS: A total of 84 children were born with pulmonary atresia and intact ventricular septum, giving an incidence of 4.2 per 100,000 live births. In all, 77 were operated on with a 1-year survival rate of 75%. Thirty-six children had ventriculocoronary communications, with a 1-year survival rate of 50%. At the end of the study period, 52 children were alive, 32 with biventricular repair, and 19 with univentricular repair. Follow-up time was 14 days-20 years (median, 6 years). Statistical analysis of incremental risk factors for death showed statistical significance for low birth weight, male sex, muscular pulmonary atresia, and having a systemic-to-pulmonary shunt as the sole initial intervention. CONCLUSION: Complete national data of all patients born with pulmonary atresia and intact ventricular septum during 1980-1999 in Sweden revealed a total mortality in accordance with previous reports for results for surgery. Further improvements demand a thorough preoperative investigation of the cardiac anatomy, particularly of the ventriculocoronary communications, to enable right ventricular decompression whenever possible.
