RESUMO
BACKGROUND: Acid reflux is often difficult to control medically. AIM: To assess the effect of 40 mg twice daily esomeprazole (high-dose) on gastric and oesophageal pH and symptoms, and biomarkers relevant to adenocarcinoma, in patients with Barrett's oesophagus (BO). METHODS: Eighteen patients, treated with proton pump inhibitors as prescribed by their treating doctor, had their therapy increased to high-dose esomeprazole for 6 months. RESULTS: At entry into the study, 9/18 patients had excessive 24-h oesophageal acid exposure, and gastric pH remained <4 for >16 h in 8/18. With high-dose esomeprazole, excessive acid exposure occurred in 2/18 patients, and gastric pH <4 was decreased from 38% of overall recording time and 53% of the nocturnal period to 15% and 17%, respectively (P < 0.001). There was a reduction in self-assessed symptoms of heartburn (P = 0.0005) and regurgitation (P < 0.0001), and inflammation and proliferation in the Barrett's mucosa. There was no significant change in p53, MGMT or COX-2 expression, or in aberrant DNA methylation. CONCLUSIONS: High-dose esomeprazole achieved higher levels of gastric acid suppression and control of oesophageal acid reflux and symptoms, with significant decreases in inflammation and epithelial proliferation. There was no reversal of aberrant DNA methylation.

Dislocation of the radial head in children with cerebral palsy (CP) is rarely reported, and the incidence of the condition is unknown. The authors present the treatment and outcome of 10 painful radial head dislocations in eight children with spastic quadriplegic-pattern CP treated over a 21-year period. Four patients were managed by open reduction of the radial head and reconstruction of the annular ligament, and four were managed by radial head excision followed by early motion. All of the patients who underwent reconstructive surgery suffered redislocation within 16 weeks of the procedure, with a return of pain and contracture of the elbow at subsequent follow-up. All four patients who underwent excision of the radial head remained pain-free, with improved elbow motion, at a follow-up of 4 years 4 months. The authors believe that once symptomatic radial head dislocation is established in CP patients, excision of the radial head gives a better final outcome than reconstructive procedures.
