RESUMO
BACKGROUND: Besides dental erosion syndrome, other oral syndromes could benefit from the stimulation of salivary secretion, in patients with gastro-oesophageal reflux disease (GORD). Our aims is evaluate the improvement of oral extra-oesophageal manifestations in patients with GORD using xylitol-malic acid tablets to stimulate salivary secretion. MATERIAL AND METHODS: The effectiveness of salivary stimulation using xylitol-malic acid tablets (as a supplement to omeprazole 40 mg/day) was assessed in a clinical trial (n = 14) lasting six months with patients with prior positive pH-metry, through GORD extra-oesophageal clinical signs, GerdQ and RDQ questionnaires, odontological variables, basal salivary secretion, stimulated salivary secretion, pH and buffer capacity, mucosal erythema index and dental wear. STATISTICS: chi-square (Haberman post-hoc), ANOVA, and Mann-Whitney U; variables between visits were evaluated with McNemar's Student's t and Wilcoxon tests; p < 0.05. RESULTS: 100% of patients not taking xylitol-malic acid presented xerostomia, but only 14.3% of patients taking xylitol-malic acid (p < 0.01) did. The mean saliva-buffer capacity at the last visit for patients not taking xylitol-malic acid was 2.14 ± 0.38, versus 2.71 ± 0.49 for patients taking xylitol-malic acid (p < 0.05). Retro-sternal burning (p < 0.05), heartburn (p < 0.05) and regurgitation (p < 0.05) were also reduced. CONCLUSIONS: Xylitol-malic acid tablets improve quality of life among patients with GORD, by reducing dry mouth, increasing saliva buffering and reducing heartburn, retro-sternal burning and regurgitation.

AIM: Upper oesophageal pH monitoring may play a significant role in the study of extra-oesophageal GERD, but limited normal data are available to date. Our aim was to develop a large series of normal values of proximal oesophageal acidification. METHODS: 155 healthy volunteers (74 male) participated in a multi-centre national study including oesophageal manometry and 24 hours oesophageal pH monitoring using two electrodes individually located 5 cm above the LOS and 3 cm below the UOS. RESULTS: 130 participants with normal manometry completed all the study. Twelve of them were excluded for inadequate pH tests. Twenty-seven subjects had abnormal conventional pH. The remaining 91 subjects (37 M; 18-72 yrs age range) formed the reference group for normality. At the level of the upper oesophagus, the 95th percentile of the total number of reflux events was 30, after eliminating the meal periods 22, and after eliminating also the pseudo-reflux events 18. Duration of the longest episodes was 5, 4 and 4 min, respectively (3.5 min in upright and 0.5 min in supine). The upper limit for the percentage of acid exposure time was 1.35, 1.05 and 0.95%, respectively. No reflux events were recorded in the upper oesophagus in 8 cases. CONCLUSION: This is the largest series of normal values of proximal oesophageal reflux that confirm the existence of acid reflux at that level in healthy subjects, in small quantity and unrelated to age or gender. Our data support the convenience of excluding pseudo-reflux events and meal periods from analysis.

Chronic abdominal pain is highly prevalent in school-aged children and is one of the most frequent disorders in our environment. The aim of the present study was to evaluate the usefulness of capsule endoscopy (CE) in patients with chronic abdominal pain. Sixteen patients (nine boys and seven girls), aged between 5 and 16 years old, with chronic abdominal pain for at least 12 months were studied. In all patients the results of hemograms, biochemical investigations, urine sediment test, Helicobacter pylori breath test and celiac serology were normal. In all children, gastroscopy, small bowel follow-through, abdominal ultrasound and colonoscopy were normal. All patients received CE by mouth. In 43.75 % of the patients studied (7/16), the capsule showed evidence of nodular lymphoid hyperplasia, mainly located in the ileum. In one girl, oxyuriasis was observed in the cecum and in another girl aphthous lesions were observed in the ileum. These lesions suggested small bowel Crohn's disease. CE mainly showed images compatible with nodular lymphoid hyperplasia, with unknown clinical significance. Consequently, we conclude that CE does not provide useful information in patients with abdominal pain without other symptoms.

OBJECTIVE: To assess the effect of a 2-week treatment with dexibuprofen, in comparison with ibuprofen and diclofenac, on pepsinogen plasma concentrations and gastrointestinal mucosa, as well as the correlation of these changes with gastrointestinal mucosal injury. METHODS: 60 patients with rheumatologic disease in chronic therapy with NSAID, were included. After a 7-day run-in period patients were randomly assigned to receive a 14-day treatment with dexibuprofen (Group A; Day 1 - 3 = 400 mg t.i.d; Day 4 - 14 = 400 mg b.i.d.), ibuprofen (Group B; Day 1 - 3 = 800 mg t.i.d; Day 4 -14 = 800 mg b.i.d.) or diclofenac (Group C; Day 1 - 3 = 50 mg t.i.d; Day 4 - 14 = 50 mg b.i.d.). Upper gastrointestinal endoscopy (Day 15), capsule-endoscopy (Day 16, 7 patients of each group) and determination of pepsinogen plasma concentrations were performed (basal and Day 15). A semiquantitative scale was designed for the assessment of the gastrointestinal mucosa. RESULTS: No differences in plasma pepsinogen were found between treatment groups or gastrointestinal injury grades or between basal and post-therapy determinations. Dexibuprofen showed gastroduodenal mucosal injury in fewer patients (42.1%) than was the case with ibuprofen (5%; p = 0.003) and diclofenac (30%; p = N.S.). Dexibuprofen administration was also associated with more patients having no intestinal mucosal damage (42.86% vs. 28.7% in the diclofenac group and 14.29% in the ibuprofen group; p = 0.0175). The rate of clinical adverse events was similar in Groups A, B and C (28%, 38% and 34%). CONCLUSIONS: Dexibuprofen showed a lower rate of gastroduodenal and intestinal mucosal injury. This effect was not mediated by modifications of plasma pepsinogen levels.

Radiation enteritis is a complex clinical entity secondary to the affectation of intestinal epithelial cells as a result of radiation in the management of pelvic malignancies that may occasionally cause intestinal strictures. We present the case of a 60 year-old woman who had been diagnosed ten years before with endometrial adenocarcinoma, and who underwent hysterectomy with double adnexectomy and subsequent radiation therapy. The patient consulted for abdominal pain and ferropenic anemia of several years standing, and had negative results following radiographic and endoscopic conventional techniques, reason why she was subjected to a capsule endoscopy study that revealed the presence of an ulcerated ileal stricture, which caused the asymptomatic retention of the capsule within the ileum. A laparotomy was subsequently performed--the strictured segment was resected and the capsule retrieved. The histologic examination of the resected segment confirmed the capsule endoscopy-raised suspicion of radiation enteritis. This case shows the role capsule endoscopy may play in the diagnosis of this condition.

BACKGROUND: Empiric triple therapy for Helicobacter pylori should be abandoned when clarithromycin resistance rate is >15-20%. Optimisation of triple therapy (high-dose acid suppression and 14-day duration) can increase eradication rates by 10%. AIM: To compare the efficacy and safety of optimised triple (OPT-TRI) and nonbismuth quadruple concomitant (OPT-CON) therapies. METHODS: Prospective multicentre study in 16 Spanish centres using triple therapy in clinical practice. In a 3-month two-phase fashion, the first 402 patients received an OPT-TRI therapy [esomeprazole (40 mg b.d.), amoxicillin (1 g b.d) and clarithromycin (500 mg b.d) for 14 days] and the last 375 patients an OPT-CON treatment [OPT-TRI therapy plus metronidazole (500 mg b.d)]. RESULTS: Seven-hundred seventy-seven consecutive patients were included (402 OPT-TRI, 375 OPT-CON). The OPT-CON therapy achieved significantly higher eradication rates in the per-protocol [82.3% (95% CI = 78-86%) vs. 93.8% (91-96%), P < 0.001] and intention-to-treat analysis [81.3% (78-86%) vs. 90.4% (87-93%), P < 0.001]. Adverse events (97% mild/moderate) were significantly more common with OPT-CON therapy (39% vs. 47%, P = 0.016), but full compliance with therapy was similar between groups (94% vs. 92%, P = 0.4). OPT-CON therapy was the only significant predictor of successful eradication (odds ratio, 2.24; 95% CI: 1.48-3.51, P < 0.001). The rate of participating centres achieving cure rates ≥ 90% favoured OPT-CON therapy (OPT-TRI 25% vs. OPT-CON 62%). CONCLUSIONS: Empiric OPT-CON therapy achieved significantly higher cure rates (>90%) compared to OPT-TRI therapy. Addition of metronidazole to OPT-TRI therapy increased eradication rates by 10%, resulting in more mild adverse effects, but without impairing compliance with therapy.

NSAIDs represent one of the most commonly used therapeutic drug groups world wide. 1.5% of the world's population is estimated as taking NSAIDs. However, their use is not risk free and gastrointestinal (GI) lesions do appear, which is indeed the main reason for their toxicity. Frequently (50%) NSAID-induced GI lesions are asymptomatic, and perforations or hemorrhages could occur without any previous symptoms. 71% of GI perforations and 50% of upper gastric hemorrhages (UGH) are associated with taking NSAIDs. How frequent GI lesions appear is directly related to whether the patient is in a risk group or not. Factors increasing the risk of GI lesions occurring are the following: being older than 60, using corticoids or other NSAIDs concomitantly, having a history of duodenal ulcer, alcohol consumption, smoking or taking oral anticoagulants. As the toxicity and how frequent the lesions appear depend on which drug is used, there is a need for research into new drugs which are both clinically effective and safer to use. GI toxicity of NSAIDs is mediated by two mechanisms, direct toxicity and prostaglandin synthesis inhibition or sistemic mechanism. Due to the relatively recent discoveries concerning the physiopathology of inflammation and gastric physiology, research into new NSAID derivatives is taking place. Such derivatives are prodrugs, galenic buffer forms, selective COX-2 inhibitors, isomeric compounds, NO-donors, and as a future possibility, phosphodiesterase inhibitors.

Early results with the use of endoscopic techniques in the treatment of gastro-oesophageal reflux disease (GERD) have been recently reported. Methods used are an injection of biocompatible substances within the lower oesophageal sphincter (LES), LES ablation using radio-frequency, and suture of folds in the area distal to the Z-line. The latter--endoscopic gastroplasty--is most difficult, but this technique has been most widely accepted by gastroenterologists to this date. Effectiveness of these endoscopic management systems in the long-term control of GERD has never been compared to a control group. This fact, together with the proven efficacy of anti-secretory drugs and the refinement of laparoscopic surgery during the past few years, has led physicians to be more demanding regarding early results. This review will discuss each method available, and issues answered by reported studies to this day are approached.

AIM: To study the usefulness and safety of capsule endoscopy as a diagnostic tool in various small bowel disorders. DESIGN: A retrospective analysis of a series of cases. MATERIAL AND METHODS: Between August 2001 and August 2002, 92 capsule endoscopy procedures were performed in 88 patients (53M/39F, age: 43.87 +/- 16.78). Indications included: chronic diarrhea (n=33); unknown abdominal pain (n=29); occult gastrointestinal bleeding or iron-deficiency anemia (n=13); abdominal discomfort in NSAID takers (n=7); staging of gastrointestinal tumors (n=4), and asymptomatic controls (n=2). Previously performed gastroscopy, colonoscopy, and small-bowel follow-through were not conclusive in all patients. RESULTS: Most frequently relevant findings included: jejuno-ileal aphtas and ulcerations (29 patients), vascular malformations (13 patients), and intestinal neoplasm (6 patients). The groups with a higher rate of findings related to this indication were occult gastrointestinal bleeding (76.92%) and chronic diarrhea (67.85%), with the lowest rate in the abdominal pain group (34.48%). Therapeutic strategy was directly changed in 36 of 88 patients (40.90%) because of capsule-endoscopic findings. The only observed complication was the failed excretion of one of the capsules because of an unknown ulcerated intestinal stricture. CONCLUSIONS: Capsule endoscopy is a safe procedure which can study the entire small bowel, meaning a valuable tool for the management of patients with suggestive signs and symptoms of intestinal disorders.

The recent emergence of capsule endoscopy has entailed a relevant diagnostic imaging advance for gastrointestinal conditions, especially those involving the small bowel. Gastrointestinal haemorrhage of obscure origin is probably the most widely accepted indication for this new technique, and promising results have been reported from series extant to date. In view of data available on this new modality, and looking forward to having wide, well designed studies fr corroboration, this paper suggests a tentative algorithm for the management of this patient group.

OBJECTIVE: To evaluate the effect of omeprazole treatment on the symptoms and lesions of patients with posterior laryngitis (PL). PATIENTS AND METHOD: Twenty-one patients with a clinical and laryngoscopic diagnosis of PL were studied. Results for each laryngeal symptom (dysphonia, hoarseness, cough, foreign body sensation, and burning) and laryngoscopic finding (mucus stasis, erythema, oedema, hypertrophy, ulceration, and granulation) at baseline, 12 weeks after treatment with omeprazole, 20 mg twice daily, and 12 weeks after treatment discontinuation were compared. No changes in their hygienic-dietary or postural habits were recommended. RESULTS: A reduction in symptom severity and frequency was observed (p < 0.05), as well as in the severity of laryngoscopic findings (p < 0.05)--except for granulation--immediately after treatment discontinuation. A relapse of laryngoscopic findings was seen at 12 weeks after treatment discontinuation (p < 0.01). The trend towards symptom recurrence was not significant. CONCLUSION: Treatment with omeprazole alone modifies clinical manifestations and endoscopic findings in patients with PL. Controlled clinical trials with a high number of patients and longer-term follow-up are needed to define the best therapeutic regimen for these patients.

OBJECTIVE: to compare the efficacy of three endoscopic therapies for achalasia and to identify predictors of response. DESIGN: prospective, single-blinded study at short and medium term. MATERIAL AND METHODS: 22 patients (9M/13 F; mean age: 47.45 +/- 21.01 years) with confirmed clinical and manometric achalasia were randomised in three groups: intrasphincteric injections of botulinum toxin (group 1: 10 patients ), injections of 1% polidocanol (group 2:6 patients), and a combined therapy with both of them (group 3: 6 patients). Clinical response was evaluated by a score (0-5) of tested symptoms (dysphagia, regurgitation and chest pain) at 1 and 24 weeks post-treatment. RESULTS: at 24 weeks post-treatment group 2 had the best complete response (CR) rate (33.33%), whereas CR in both the botulinum toxin and combined therapy groups was 10 and 0%, respectively. Groups 1 and 2 got an overall improvement in clinical score at 1 (p= 0.02) and 24 weeks (p= 0.04). Five patients (50%) in group 1, two patients (33.33%) in group 2, and three patients (50%) in group 3 needed other therapies (dilation or surgery) because of treatment failure. Separately, neither age nor sex, time from diagnosis or type of therapy could distinguish responders from non-responders in these three groups. However, absence of response within the first week, and an initial clinical score above 7 were predictive factors of poor response at six months. CONCLUSIONS: short- and medium-term clinical response to these endoscopic therapies was limited. The absence of response at seven days and a severe initial clinical score were predictive factors of poor medium-term response.

Wireless endoscopy consists of a small-sized device which allows gastrointestinal tract images to be taken as it physiologically advances along its lumen after being orally ingested. Its primary contribution is the study of small bowel conditions, a gastrointestinal tract segment in which diagnosis difficulties still arise when using current tests, including enteroscopy. Preliminary studies in animals and healthy subjects have revealed data on image quality, sensitivity, specificity, and safety that demonstrate the benefits of this new technique. This review discusses technical aspects, indications and contraindications, as well as studies reported so far on this endoscopic diagnostic procedure.

OBJECTIVE: to determine the changes in acid output before and after eradication therapy in patients with duodenal ulcer associated with Helicobacter pylori infection. METHOD: the subjects of this prospective study were 16 patients with acute duodenal ulcer at endoscopy and H. pylori infection determined by rapid urease test and histology. They were randomly assigned to receive treatment with pantoprazole 40 mg b.i.d., clarithromycin 500 mg b.i.d. and amoxicillin 1 g b.i.d. during 7 or 14 days. Endoscopic examination and biopsy were repeated 4 weeks after treatment ended. The changes in acid output before and after treatment were calculated by the morphometric quantification of parietal cell canaliculi from the gastric corpus. To this end 20 parietal cells from the medial glandular zone were selected and canalicular index was calculated, before and after eradication therapy, with a morphometric method based on automatic analysis of histological images. RESULTS: canalicular index was 26.4 +/- 1.4 (mean +/- standard error of the mean) before treatment, and 20.5 +/- 1 (p < 0.01) after therapy. CONCLUSIONS: morphometric analysis showed a decrease in acid output in patients with duodenal ulcer associated with H. pylori infection 4 weeks after eradication therapy with clarithromycin, amoxicillin and pantoprazole.

Wireless endoscopy is a new noninvasive diagnostic method that is able to visualize small bowel lesions. The instrument is small and carries a battery and microcamera that takes two photographs per second. It is indicated in cases of bleeding of unknown origin and for the diagnosis of inflammatory bowel disease, among other disorders. To date, it has mainly been used in adults. We believe that this instrument could play an important role in the pediatric age group since it is noninvasive and can be used to diagnose small bowel lesions, thus avoiding unnecessary diagnostic tests. We report the case of a girl with suspicion of Crohn's disease that was unconfirmed by conventional endoscopic techniques. The capsule showed small bowel lesions compatible with Crohn's disease. Corticosteroid treatment was initiated and the patient is now in clinical remission.

BACKGROUND: To evaluate disease-specific health-related quality of life (HRQoL) in patients with symptomatic esophageal achalasia before and after therapy. METHODS: Symptoms and disease-specific HRQoL were evaluated before and 3 months after therapy. Therapy selection, either dilatation or myotomy, depended exclusively on the opinion of the physician on charge of the patient. Symptom severity was graded from 0 to 3, using a scoring system. A disease-specific questionnaire for achalasia developed and validated in Spanish language with 18 items and four subscales (AE-18) was used to evaluate HRQoL. Changes after therapy in HRQoL and its association with clinical improvement were analyzed. KEY RESULTS: Sixty-five patients were prospectively included in eight hospitals in Spain. Of them, 47 were treated with dilatation, and 18 with laparoscopic Heller myotomy. After therapy, AE-18 global and subscales scores improved significantly. Changes in HRQoL were associated with improvement in symptoms. An important improvement in symptoms (>or=50%) was needed to obtain a minimal clinically important improvement (>or=20%) in HRQoL. CONCLUSIONS & INFERENCES: Disease-specific HRQoL improves in patients with symptomatic achalasia after therapy with dilatation or myotomy. The degree of improvement of HRQoL depends on the degree of improvement of esophageal symptoms.
