- Ulcer and bleeding complications and their relationship with dyspeptic symptoms in NSAIDs users: a transversal multicenter study(2014) DIB, Ricardo Anuar; CHINZON, Decio; FONTES, Luiz Henrique de Souza; TEIXEIRA, Ana Cristina de Sa; NAVARRO-RODRIGUEZ, TomasObjectives. To evaluate the prevalence of lesions and digestive complications secondary to the use of non-steroidal anti-inflammatory drugs (NSAIDs), the clinical profile seen for digestive complaints and the relation with the endoscopic findings. Methods. Prospective, multicentric, open study, evaluating consecutively 1231 patients, divided as follows: group I NSAID and group II - non-NSAID. All patients answered questionnaire to evaluate the onset, the type of clinical complaint, the use of medication and possible complications associated to digestive bleeding. Results. A total of 1213 patients were evaluated. Among them, 65% were female and 13.1% were smokers; 15.6% mentioned they ingested alcoholic beverages. The main signs and symptoms reported were epigastralgy and pyrosis (67% and 62%, respectively). The upper gastrointestinal (UGI) endoscopy was normal in 3.9% in group I and in 10.7% in group II (p < 0.001). Patient who do not use NSAID will be 2.5 times more likely to have normal UGI endoscopy (p = 0.001). The presence of erosive or ulcer lesions in the stomach and duodenum was more frequent in group I. The incidence of lesions in the stomach when compared to the duodenum is observed (erosions: 49.12% vs. 13.60%, p = 0.001; ulcers: 14.04% vs. 11.84%, p = 0.05). The risk of digestive bleeding is 12 times higher (6.14% vs. 0.51%) in those who used NSAIDs, and the stomach is the site in which bleeding occurs more frequently. Conclusions. The frequency of gastric ulcer, duodenal ulcer and digestive bleeding was higher in patients who used NSAIDs. There was no connection found between endoscopic findings and dyspeptic symptoms.

METHOD: The time to gastric emptying of a semi-solid diet was assessed via ultrasonography in 28 patients with Chagasic megaesophagus (grades I, II, and III) and compared to that of a control group (n = 15). After measurement of antral diameter under fasting conditions, 400mL of a semi-solid diet were administered and consecutive measurements were performed every 30 min. RESULTS: The duration of dysphagia was significantly lower in patients with megaesophagus grade I than in those with grades II or III. The time to gastric emptying was significantly increased in the megaesophagus group compared to the control group. The means of antral areas measured under fasting conditions and after maximal antral distension did not differ between the megaesophagus and control groups. CONCLUSION: The time to gastric emptying of a semi-solid diet was significantly greater in patients with Chagasic megaesophagus than in controls. The delay did not depend on the extent of dilatation of the megaesophagus or the duration of dysphagia.
- Increase of lower esophageal sphincter pressure after osteopathic intervention on the diaphragm in patients with gastroesophageal reflux(2013) SILVA, R. C. V. da; SA, C. C. de; PASCUAL-VACA, A. O.; FONTES, L. H. de Souza; FERNANDES, F. A. M. Herbella; DIB, R. A.; BLANCO, C. R.; QUEIROZ, R. A.; NAVARRO-RODRIGUEZ, T.The treatment of gastroesophageal reflux disease may be clinical or surgical. The clinical consists basically of the use of drugs; however, there are new techniques to complement this treatment, osteopathic intervention in the diaphragmatic muscle is one these. The objective of the study is to compare pressure values in the examination of esophageal manometry of the lower esophageal sphincter (LES) before and immediately after osteopathic intervention in the diaphragm muscle. Thirty-eight patients with gastroesophageal reflux disease - 16 submitted to sham technique and 22 submitted osteopathic technique - were randomly selected. The average respiratory pressure (ARP) and the maximum expiratory pressure (MEP) of the LES were measured by manometry before and after osteopathic technique at the point of highest pressure. Statistical analysis was performed using the Student's t-test and Mann-Whitney, and magnitude of the technique proposed was measured using the Cohen's index. Statistically significant difference in the osteopathic technique was found in three out of four in relation to the group of patients who performed the sham technique for the following measures of LES pressure: ARP with P= 0.027. The MEP had no statistical difference (P= 0.146). The values of Cohen d for the same measures were: ARP with d= 0.80 and MEP d= 0.52. Osteopathic manipulative technique produces a positive increment in the LES region soon after its performance.
bookPart Constipação intestinal funcional(2013) NAVARRO-RODRIGUEZ, Tomás; DIB, Ricardo Anuar; CHAVES, Renata Carvalho de Miranda; MORAES-FILHO, Joaquim Prado Pinto de- High definition endoscopy and ""narrow band imaging"" in the diagnosis of gastroesophageal reflux disease(2014) ASSIRATI, Frederico Salvador; HASHIMOTO, Claudio Lyoiti; DIB, Ricardo Anuar; FONTES, Luiz Henrique Souza; NAVARRO-RODRIGUEZ, TomasIntroduction: The gastroesophageal reflux disease is a common condition in the western world but less than half of patients present endoscopic abnormalities, making a standard procedure unsuitable for diagnosis. High definition endoscopy coupled with narrow band imaging has shown potential for differentiation of lesions and possible biopsy, allowing early diagnosis and treatment. Methods: This review describes the principles of biotic and their influence in obtaining images with better definition of the vessels in the mucosa, through the narrow band imaging. Selected papers using it in patients with reflux disease and Barrett's esophagus are analyzed in several ways, highlighting the findings and limitations. Conclusion: The meaning of the narrow band imaging in the endoscopic diagnosis of reflux disease will be defined by large scale studies, with different categories of patients, including assessment of symptoms and response to treatment.
