    Notes: A study was made to investigate the biological principle of new attachment of connective tissue to periodontally diseased root surfaces utilizing the previous finding that topical application of citric acid to the affected area may stimulate periodontal regeneration. Reconstructive surgery was performed on ten surfaces of nine teeth involved in advanced chronic periodontal disease. A muco-periosteal flap was raised and the apical extent of existing subgingival calculus was demarcated by a notch made through the calculus and into the root. Following thorough instrumentation, a saturated solution of citric acid was applied to the root surface for five minutes and the flap repositioned and sutured. Four months later the teeth with attached periodontal tissues were removed and processed for histological analysis. Connective tissue regeneration characterized by deposition of new cementum, and more coronally, by tightly apposed soft connective tissue had occurred in all specimens. The junctional epithelium ended 1.2–2.6 mm coronal to the apical border of the notch in the various specimens. The results demonstrate that regeneration of periodontal tissues to a root surface that has become denuded as a result of chronic, destructive periodontal disease and that has been covered by calculus is, in fact, a biological possibility. This study does not establish whether or not acid conditioning of the root surface is a prerequisite for new attachment.

    Notes: Background: Successful treatment of Helicobacter pylori infection results in cure of peptic ulcer disease. Multidrug regimens are needed to cure this infection. We studied the effectiveness and side effect profile of two antibiotics active against Helicobacter pylori, metronidazole and clarithromycin, combined with omeprazole. Methods: We evaluated a combination therapy for H. pylori infection consisting of metronidazole (500 mg b.d.), omeprazole (20 mg b.d.), and clarithromycin (250 mg b.d.) for 2 weeks, followed by ranitidine 300 mg daily for 4 weeks. Results: Thirty-three patients with documented H. pylori infection were studied. Twenty had previously failed antimicrobial therapy, including one with metronidazole-based triple therapy and eight with macrolide-based therapy (five with clarithromycinbased therapy), and 11 with amoxycillin, tetracycline, and bismuth. H. pylori status was determined by histopathology using the Genta stain and by culture. H. pylori status was determined at entry and 4 weeks after completing antimicrobial therapy. The H. pylori infection was cured in 88% (95% CI = 72%–96%) including 90% of those who had failed previous anti-H. pylori therapies. Mild side effects were reported by 18%. Conclusion: We conclude that the combination of metronidazole, omeprazole and clarithromycin is an effective treatment for H. pylori infection.

    Notes: Background: The combination of 120 mg of omeprazole (40 mg t.d.s.) and amoxycillin has been reported to be effective for treating H. pylori infections. Methods: Normal volunteers with H. pylori infection received high-dose omeprazole (40 mg t.d.s.) or lansoprazole (60 mg t.d.s.) plus amoxycillin 750 mg t.d.s. for 14 days. The studies were open label and not randomized as those receiving omeprazole plus amoxycillin had previously failed lower dose omeprazole (20 mg b.d.) plus amoxycillin therapy more than 6 months previously. Those receiving lansoprazole plus amoxycillin had not been previously treated. Four to 6 weeks after ending antimicrobial therapy, H. pylori status was determined by Genta stain of gastric mucosal biopsies. Results: Forty-three volunteers entered the study and 41 completed it. The overall success with high-dose proton pump inhibitor plus amoxycillin was 34.9%. For the individual regimens the per-protocol results were 48% (95% CI=28–69%) with lansoprazole and 12.5% (95% CI=2–38%) with omeprazole. Compliance was 〉95% for both regimens. Side-effects were experienced by four lansoprazole and three omeprazole subjects, and caused two omeprazole subjects to withdraw. Cure rates were similar among different races and ethnic groups, between men and women, and between smokers and non-smokers. The level of the pre-treatment urea breath test also did not predict outcome. Conclusion: High-dose proton pump inhibitor plus amoxycillin combinations for treatment of H. pylori infection yielded unacceptable results, as the 95% confidence intervals did not include an 80% cure rate. These combinations do not yield consistent results worldwide and cannot be recommended as primary therapy.

    Notes: Background: Multi-drug regimens are generally required to reliably cure Helicobarter pylori infection. Metronidazole, clarithromycin and omeprazole has proven to be an effective combination therapy with a cure rate of 90% or greater. Methods: We evaluated a 14-day combination regimen for H. pylori infection consisting of metronidazole 500 mg b.d., clarithromycin 250 mg b.d. and ranitidine 300 mg b.d. (MRC) instead of omeprazole. Ranitidine alone was continued for an additional 4 weeks. H. pylori status was determined by rapid urease testing. histopathology using the Genta stain, and by culture at entry and 4 weeks after completing antimicrobial therapy. Results: Twenty-seven patients with documented peptic ulcer disease and H. pylori infection were treated. Five had previously failed macrolide-based antimicrobial therapy: none had received metronidazole. All ulcers were healed at week 6 except one patient taking naproxen; his H. pylori infection was cured. Overall, H. pylori infection was cured in 78% (95% CI = 58–91%). In patients with clarithromycin-sensitive isolates, the cure rate was 20 of 23 (87%, 95% C.I. = 66–97%); only one of four patients (25%) with clarithromycin-resistant isolates was cured. In contrast, four of five patients with metronidazole-resistant isolates were cured (80%). In patients with isolates sensitive to both antibiotics, the cure rate was 16 of 18 (89% 95% C.I. = 65–99%). Mild side effects were reported by 27%, including diarrhoea and altered taste. Compliance averaged 98%. Conclusion: These results suggest that the combination of metronidazole, ranitidine and clarithromycin results in high cure rates in patients with clarithromycin-sensitive isolates. Omeprazole may not be required for Bazzoli's triple therapy; and large multicentre comparative trials are indicated.

    Notes: [Auszug] TRAVELLING this evening between Plymouth and Exeter, I pulled the screens over the light in my compartment to enjoy the moonlight, and was rewarded by seeing a fine display of aurora borealis, which was, I hope, witnessed by some other of your readers.

    Notes: [Auszug] I HAVE tried Mr. G. W. Walker's experiment with a small Wimshurst, with 8″ plates, and find that the reversal he mentions generally takes place, but not always. In my case, however, the machine is made so as to excite either way, and the reversal will not take place unless excitation has ...
