Aims: To compare safety and efficacy of on-demand pantoprazole 20 mg/40 mg versus placebo in the long-term management of patients with mild gastroesophageal reflux disease (GERD) after heartburn relief. Methods: A total of 634 patients with endoscopically confirmed GERD grade 0/I and heartburn were included. During the acute phase, patients were treated with pantoprazole 20 mg once daily for 4 weeks. Those patients relieved from heartburn entered the long-term phase, and were randomly assigned to either treatment group pantoprazole 20 mg, 40 mg or placebo. Over 6 months, patients took study medication on demand (antacids as rescue medication) and discontinued the drug once symptoms abated. Results: After 4 weeks a total of 87.1%/90.0% of patients were free of heartburn (ITT/PP), and entered the subsequent long-term phase. The perceived average daily symptom load (placebo: 3.93, pantoprazole 20 mg: 2.91, pantoprazole 40 mg: 2.71, ITT) and the number of antacid tablets taken (average number, placebo: 0.68, pantoprazole 20 mg: 0.45, pantoprazole 40 mg: 0.33, ITT) were significantly higher in the placebo than in both pantoprazole groups (p < 0.0001), with no statistically significant difference between the two pantoprazole groups. The discontinuation rate due to insufficient control of heartburn was significantly lower in both pantoprazole groups compared to placebo (placebo: 10.9, pantoprazole 20 mg: 2.8, pantoprazole 40 mg: 0.9, ITT). Conclusions: Our findings favor on-demand treatment with pantoprazole 20 mg for the long-term management of heartburn in patients with uncomplicated GERD (grade 0/I) with superiority to placebo.

Abstract Dyslexia (reading and spelling disability) is one of the most frequently diagnosed disorders in childhood. Twin studies of dyslexia have indicated that deficits in spelling are substantially heritable and that the heritability of spelling deficits is higher than the heritability of reading deficits. We conducted a linkage study for spelling disability in seven multiplex families from Germany. Following previously reported linkage findings of components of dyslexia to chromosome 6p21-p22 and 15q21, we genotyped 26 microsatellite markers covering all of chromosome 6, and 13 microsatellite markers covering all of chromosome 15. While the chromosome 6 data were negative, results from chromosome 15 markers supported a locus on 15q21. The highest two-point LOD score was 1.26 with marker D15S143 at theta = 0. A multipoint LOD score of 1.78 (p = 0.0042) was achieved with a maximum at D15S132. Thus, our results provide independent support for a dyslexia gene on the long arm of chromosome 15.
