Rabeprazole,clarithromycin, and amoxicillin Helicobacter pylori eradication therapy: Report of an efficacy study

AIM:To investigate the efficacy of a standard triple therapy(comprising rabeprazole,clarithromycin,and amoxicillin)for Helicobacter pylori(H.pylori)eradication,noting factors that influence the outcome and documenting any adverse events.METHODS:Following institutional ethical approval,fifty consecutive and consenting symptomatic patients with evidence of H.pylori infection by either a positive urea breath test(UBT)and/or a campylobacter-like organism test who presented to the Gastroenterology clinic of Lagos State University Teaching Hospital between 2012 and 2013 were recruited into the study.Patients were openly randomized to either a 7-d or a 10-d regimen of amoxicillin 1 g,clarithromycin 500mg and rabeprazole 20 mg twice daily.The extent of symptom resolution was noted following the treatment,and at the end of one month after the completion oftreatment,a repeat UBT was performed in each patient to document the eradication of the infection.All data(demographics,symptoms,and eradication rates)were collated and analyzed with SPSS version 18.RESULTS:Forty-seven patients completed the study(three were excluded from the analysis for breaching the study protocol).The patients included 18 males and 29 females within the age range of 13-80 years(mean 43.7,SD 16.8).The clinical features of the study subjects were dyspepsia,reflux symptoms and features of gastrointestinal bleeding.The average eradication rate was 87.2%.Eighteen subjects were enrolled in the 7-d arm,while 29 were in the 10-d arm.There was no statistically significant difference in the age or sex distributions of the two arms.There was no significant advantage of the 10-d treatment duration over the 7-d duration(P=0.78),and the eradication outcomes were not influenced by the gender or age of the subjects.No adverse effects were reported in either arm.CONCLUSION:The triple therapy regime,employing a combination of amoxicillin,clarithromycin and rabeprazole,showed great efficacy and safety in the eradication of H.pylori,and this outcome was not influenced by gender or age.No difference was observed between the 7-d and 10-d regimens.

Comparative analysis of preemptive analgesic effect of tramadol chlorhydrate and nimesulide following third molar surgery

The aim of this prospective, randomized, controlled, paired trial was to perform a comparative analysis of the preemptive analgesic effect of nimesulide and tramadol chlorhydrate during third molar surgery. The study was carried out between March and November 2009, involving 94 operations in 47 male and female patients with bilateral impacted lower third molars in comparable positions. The sample was divided into two groups. Group A received an oral dose of 100 mg of nimesulide 1 h prior to surgery. Group B received an oral dose of 100 mg of tramadol chlorhydrate 1 h prior to surgery. The following aspects were evaluated in the postoperative period: adverse effects of the drugs; amount of rescue medication used (acetaminophen 750 mg); and pain 5, 6, 24, 36, 48, 60, 72 and 84 h after surgery using a visual analog pain scale. Peak pain occurred 5 h after surgery in both groups, with a mean pain score of 2.3 in Group A and 3.0 in Group B; this difference did not achieve statistical significance (p > 0.141). Based on the sample studied, nimesulide and tramadol chlorhydrate demonstrate similar preemptive analgesic effects when used in lower third molar surgeries.     

Traumatic bone cyst of the mandible: a review of 26 cases

The traumatic bone cyst is characterized by the presence of an asymptomatic sinus devoid of epithelial lining, which is rarely found in the jaws.ObjectiveTo describe the clinical, surgical and radiographic findings of traumatic bone cysts.Material and MethodA retrospective study was made of patients diagnosed with traumatic bone cysts at an oral pathology department from 1992 to 2007. Data on the clinical, radiographic and surgical complications were gathered.ResultsTwenty-six cases of traumatic bone cyst were diagnosed in 15 years; 17 were male and 09 were female. Most patients were within first two decades of life and had no pain or history of trauma in the affected area. The multilocular pattern was observed in only seven cases, its radiographic appearance suggests a tumor. Air was found inside the lesion in about 70% of cases; serous fluid with blood and blood only were uncommon within the lesions.ConclusionA higher prevalence in young patients, absence of a history of trauma, and a small number of lesions containing serous fluid with blood reflects the need to discuss the true pathogenesis of traumatic bone cysts.
