Maladies peptiques [Acid related diseases progress in 2007].

The treatment of reflux disease did not changed. PPI treatment remains the first line treatment and surgery a second line treatment. The effect of surgery in reflux disease reduces and, after ten years, a part of the operated patients needs PPI again. The triple therapy is the treatment of choice of Helicobacter pylori infection. Patients with persistent Helicobacter pylori infection, after a first treatment, should be treated with a sequential treatment. PPI are effective in the prevention of gastroduodenal lesions and in the treatment of dyspeptic symptoms during NSAID treatment. IPP should be given to all patients presenting dyspeptic symptoms under NSAID or COX-2 administration.

Boerhaave Syndrom: an unusual complication of acute vomiting in a child

Introduction: Boerhaave syndrome (BS) is a spontaneous esophageal perforation, described in aged, alcoholic males, secondary to forceful vomiting. BS has rarely been described in children. Case presentation: The patient is a 7-year-old Nigerian girl. She has a past history of clinical gastro-esophageal reflux (treated conservatively with prokinetics and good evolution), malaria at the age of 3 months and an episode of acute pancreatitis at 5 years. One week prior admission, she had stopped atovaquone-proguanil (AP) prophylaxis after a trip in an endemic area. Two days prior admission, she presented several bouts of isolated acute vomiting, without fever or diarrhea. On admission, she complained of chest pain. Cardiac auscultation revealed crepitus. No subcutaneous emphysema nor respiratory distress was present. Chest radiography and CT-scan confirmed a pneumomediastinum extending to the neck. Esophageal perforation was suspected. An upper gastrointestinal endoscopy was performed and showed a small esophageal tear, grade II-III esophagitis and a single gastric ulcer without any sign of H. Pylori infection. Enteral feeds were stopped and a nasogastric sucking tube inserted. The patient made a full recovery on intravenous antibiotics and conservative treatment. Of note a second episode of subclinical acute pancreatitis, treated conservatively, probably drug-induced. Discussion: BS is a complete rupture of all layers of the esophagus, secondary to an increased intra-abdominal pressure due to incomplete opening of the cricophayngeal sphincter occurring during vomiting or cough. Rarer causes include eosinophilic or Barrett's esophagitis, HIV and caustic ingestion. Esophageal perforation in children is rare, most of time secondary to necrotizing esophagitis in the newborn, medical intervention (endoscopy, sucking, or intubation) or trauma in the older child. Our patient had none of those risk factors and it is still unclear what predisposed her to this complication. However, we believe that preceding forceful vomiting with increased abdominal pressure acting on a weakened oesophagus due to esophagitis might be responsible. We could not find any association in the literature between AP and BS nor between BS and acute pancreatitis. The origin of her recurrent pancreatitis remains unclear, reason for which genetic testing for mutations in the trypsinogen, trypsin inhibitor and CFTR genes will be performed in case of a third episode.

Maladies peptiques [Progress in 2008 for acid related diseases]

The treatment of reflux disease did not change in the review period. PPI therapy remains the first line treatment and surgery the second line approach. Endoscopic anti-reflux procedures should be only performed in controlled studies. Beside the classic triple therapy, sequential treatment of Helicobacter pylori infection can today be considered as a first line therapy. PPI are effective in the prevention of gastroduodenal lesions and in the treatment of dyspeptic symptoms induced by NSAIDs treatment. Only patients younger then 65 years and without any risk factors do not need a preventive PPI prescription during classic NSAIDS treatment.

One case, 3 rare simultaneous findings: intramyocardial bronchogenic cyst, P.H558R variant of SCN5A gene, and granular cell tumor of the esophagus.

We describe the sudden death of a 42-year-old white man. The decedent was a healthy young man with a short clinical history of chest pain, fatigue, dizziness, and pyrosis. Two weeks before his death, he underwent medical evaluation for the aforementioned symptoms. Electrocardiogram, chest x-ray, and serum troponin were all within normal limits. Gastroesophageal reflux disease was suspected, and the decedent was treated with omeprazole. Medicolegal autopsy disclosed an incidental intramyocardial bronchogenic cyst and p.H558R variant of the SCN5A gene. The cyst was located between the epicardium and myocardium of the posterior face of the left superior ventricular wall, adjacent to the base of the heart. An incidental granular cell tumor of the esophagus was also identified, which was likely unrelated to death.

Sténose oesophagienne non-néoplasique: pas toujours si bénigne [Non-neoplastic esophageal stenosis: not always so benign].

Esophageal intramural pseudodiverticulosis is a rare pathology whose etiology is unknown, but which is frequently associated with three highly prevalent entities: esophageal reflux disease, esophageal candidosis and alcoholic esophagitis. With conservative treatment the course of these pathologies is usually benign. However, some severe cases are resistant to conservative treatment and may require more aggressive management. We here present the case of patient suffering from a severe esophagitis complicated by chronic mediastinitis with life-threatening repercussions, requiring esophagectomy as treatment.

Oesophagite à éosinophiles [Eosinophilic esophagitis].

Eosinophilic esophagitis is a recent diagnosis, of growing interest and prevalence. It has to be considered by every physician when facing any adult or pediatric case of dysphagia, food impaction, and symptoms of GERD (gastroesophageal reflux disease) resistant to proton-pump inhibitor treatment. The diagnosis is made by combining clinical symptoms and endoscopic signs, supported by biopsies of the mucosa, which should show more than 15 eosinophils per high power field. The etiology seems to be of allergic origin, and a full immuno-allergic testing should be made. Recommendations for the treatment are to calm down the inflammatory process by proton-pump inhibitors, and to give topical steroids, keeping the systemic treatment for acute severe cases. In cases of esophageal stenoses, dilations can be undertaken, but with a high risk of recurrence.

Stress ulcer prophylaxis in non-critically ill patients: a prospective evaluation of the practice in a surgical ward

Introduction The benefit of stress ulcer prophylaxis (SUP) in noncriticallyill patients has not been proved. Over-prescription of SUP isnot devoided of risks (i.e. drug-drug interactions, adverse events).This prospective study aimed to evaluate the use of proton pumpinhibitors (PPIs) for SUP in a visceral surgery ward.Materials & Methods Data collection was performed prospectivelyduring a 8-week period on patients hospitalized in a visceral surgeryward (58 beds). Patients with a PPI prescription for the treatment ofulcers, gastroesophageal reflux disease, esophagitis or epigastralgiawere excluded as well as patients hospitalized twice during the studyperiod. The American Society of Health-System Pharmacists guidelineson SUP were used to assess the appropriateness of de novo PPIprescriptions.Results Among 255 patients in the study, 138 (54.1%) received aprophylaxis with PPI, of which 86 (62.3%) were de novo PPI prescriptions.93.5% of patients received esomeprazole (according to thehospital drug formulary) mainly orally at 40 mg qd. 79.1% of patientshad no risk factors for SUP. 17.9% and 3.0% had one and two riskfactors, respectively. 95% of the patients with PPI were not hospitalizedin the intensive care unit (ICU) before their stay in the visceralsurgery ward. At discharge, PPI therapy was continued in 34.2% ofpatients with a de novo PPI prescription.Discussion & Conclusion This study highlights the over-utilizationof PPIs in non-ICU patients and the inappropriate continuation of PPIprescriptions at discharge. The PPI dosage prescribed for prophylaxiswas probably too high compared with the data of the literature.Treatment recommendations for SUP are needed to restrict PPIuse for justified indications.

Pediatric and adult eosinophilic esophagitis: similarities and differences.

Early in the 1990s, several case series described adults suffering from dysphagia and children with refractory reflux symptoms, both accompanied by an eosinophil-predominant infiltration, thereby conclusively distinguishing it from gastroesophageal reflux disease. Eosinophilic esophagitis (EoE) was recognized as its own entity in the adult and in the pediatric literature. In the last decade, evidence has accumulated that EoE represents a T-helper (Th)2-type inflammatory disease. Remodeling of the esophagus is a hallmark of EoE, leading to esophageal dysfunction and bolus impaction. Familial occurrence and disease association with single-nucleotide polymorphisms underscore the influence of genetics in this disease. Eosinophilic esophagitis may affect individuals at any age, although the clinical presentation is highly age dependent. There is a significant allergic bias in the EoE population, with the majority of patients having concurrent allergic rhinitis, asthma, eczema, and/or a history of atopy. One noteworthy difference is that in children, EoE seems to be primarily a food antigen-driven disease, whereas in adults, mainly aeroallergen sensitization has been observed. Treatment modalities for EoE include the 3Ds: drugs, diet, and dilation. The crucial question of whether adult and pediatric EoE are different phenotypes of one single entity or whether we are confronted with two different diseases is still open. Here, we review similarities and differences between EoE in adults and children.

Traitements chirurgicaux des maladies fonctionnelles oesogastriques [Surgical treatment of gastroesophageal diseases].

Les pathologies fonctionnelles oesogastriques regroupent plusieurs maladies touchant la fonction digestive haute : la maladie de reflux, les hernies hiatales, l'oesophage court et l'achalasie. Leur mode de présentation est parfois similaire, mais leur traitement diffère sur de nombreux points. L'approche initiale passe souvent par une modification de l'hygiène de vie et une prise en charge médicale. Mais une prise en charge chirurgicale est parfois nécessaire. Une sélection très stricte des patients permet de garantir un bon résultat à long terme, tout en limitant le risque de complications. Elle repose sur un bilan fonctionnel précis et une prise en charge dans le cadre de discussions multidisciplinaires. Cette revue fait un point actuel sur la prise en charge générale, les bilans nécessaires et les traitements chirurgicaux disponibles. Gastroesophageal functional diseases comprise several pathologies impending upper gastrointestinal function: reflux disease, hiatal hernias, short esophagus and achalasia. Their presentation may be similar, but their treatment differs on many points. The initial approach consists of lifestyle changes and medical management. However, surgical treatment is sometimes necessary. Strict patient selection ensures good long-term results, while limiting the risk of complications. This selection is based on precise functional assessment and management in the context of multidisciplinary discussions. This article aims to discuss current aspects on general management, functional investigations and surgical treatments available.

Population-based multicase-control study in common tumors in Spain (MCC-Spain): rationale and study design

INTRODUCTION: We present the protocol of a large population-based case-control study of 5 common tumors in Spain (MCC-Spain) that evaluates environmental exposures and genetic factors. METHODS: Between 2008-2013, 10,183 persons aged 20-85 years were enrolled in 23 hospitals and primary care centres in 12 Spanish provinces including 1,115 cases of a new diagnosis of prostate cancer, 1,750 of breast cancer, 2,171 of colorectal cancer, 492 of gastro-oesophageal cancer, 554 cases of chronic lymphocytic leukaemia (CLL) and 4,101 population-based controls matched by frequency to cases by age, sex and region of residence. Participation rates ranged from 57% (stomach cancer) to 87% (CLL cases) and from 30% to 77% in controls. Participants completed a face-to-face computerized interview on sociodemographic factors, environmental exposures, occupation, medication, lifestyle, and personal and family medical history. In addition, participants completed a self-administered food-frequency questionnaire and telephone interviews. Blood samples were collected from 76% of participants while saliva samples were collected in CLL cases and participants refusing blood extractions. Clinical information was recorded for cases and paraffin blocks and/or fresh tumor samples are available in most collaborating hospitals. Genotyping was done through an exome array enriched with genetic markers in specific pathways. Multiple analyses are planned to assess the association of environmental, personal and genetic risk factors for each tumor and to identify pleiotropic effects. DISCUSSION: This study, conducted within the Spanish Consortium for Biomedical Research in Epidemiology & Public Health (CIBERESP), is a unique initiative to evaluate etiological factors for common cancers and will promote cancer research and prevention in Spain.

Leiomioma do esôfago removido por videolaparoscopia

This report describes a leiomyoma of the inferior third section of the esophagus removed during laparoscopic cholecystectomy. The patient is a woman 55-years-age, carrying esophageal myoma of 40 mm in diameter wide, situated in the posterior wall of the lower esophagus. Indications for surgery were based mainly on the growth of the mass (6 mm when discovered 7 years previously, increased to 40 mm). Recently the patient returned suffering from pain, which could be attributed to his litiasic cholecystopaty. A small degree of low disphagia could also be observed. Radiologic imaging, direct endoscopic examination and endoscopic ultrasound showed that the mioma protruded on to the oesophagic lumen, discreetly diminishing there. A laparoscopic esophageal myomectomy was indicated at the same session of the laparoscopic cholecystectomy. Once the pneunoperitoneum was installed, five ports were placed as if for a hiatus hernia surgery. The cholecystectomy was uneventful. Next, an esophagoscopy was performed so as to determine the precise area covering the base of the tumour; at the right-lateral site. Longitudinal and circular fibres of the esophagus was severed over the lesion and the enucleation of the tumour was performed alternating the monopolar dissection, bipolar and hidrodisection. Control-endoscopy was carried out to verify mucosa integrity. Four suture points with poliglactine 3-0 string so as to close the musculature followed this. One suture was placed in for diminution of the size of the esophagean hiatus. Total time of intervention: two hours (30m for the cholecystectomy and one hour and thirty minutes for the myomectomy). Postoperative period: uneventful. Disappearance of the disphagia was observed. Radiologic transit control with water-soluble contrast at 4th post-operative day: good passage. Diagnosis from laboratory of pathology: conjunctive tumour formed by muscle non-striated cells: leiomyoma. The patient was re-examined on the two-month postoperative follow-up. General conditions were good and there were no complain of dysphagia. Neither there were any symptoms of gastro-esophageal reflux.

Esôfago de Barrett: aspectos fisiopatológicos e moleculares da seqüência metaplasia-displasia-adenocarcinoma - artigo de revisão

The Barrett's esophagus (BE) is defined as endoscopically visible columnar mucosa at the distal esophagus, of any extension, proved to harbor intestinal metaplasia on biopsy, highlighted by the presence of goblet cells. BE denotes long-standing gastroesophageal reflux disease (GERD) and is an important risk factor for the development of esophageal adenocarcinoma (EAC). Therefore, these patients must be on follow-up, in order to diagnose cancer early. BE patients have frequent alterations in esophageal physiologyc studies. Alkaline duodenogastroesophageal reflux seems to have important role. The development BE occurs in steps, initially with formation of cardiac type mucosa subsequent intestinalization. Futher progression can follow a sequence, from low grade dysplasia, to high grade dysplasia and esophageal adenocarcinoma. Current follow-up is based on the presence of dysplasia. It has limitations, grouping patients heterogeneously. Different steps of carcinogenesis have been studied looking for an ideal prognostic marker. Uncontrolled proliferative activity, apoptosis inhibition, angiogenesis, tissue invasion and metastases formation are all implicated in cancer origin. Some cycle cell molecules have been studied in BE, such as retinoblastoma protein, ciclins, kinase dependent ciclins and cell cycle inhibitors. The P53 protein is one of the most investigated in the metaplasia-adenocarcinoma progression. Growth Factors, apoptotic proteins, telomers and DNA ploidy have also been searched. Increased proliferative activity has been implicated in Barrett's carcinogenesis and the Ki-67 antigen, through imunohistochemical analysis, has become the the method of choice. Present in the nucleus, it is found in proliferative cells only. Some studies suport association between Ki-67 activity and the metaplasia-dysplasia-adenocarcinoma sequence.The results, however, are inconclusive and research should follow this way.

Qualidade de vida em gestantes no terceiro trimestre com pirose e/ou regurgitação : contribuição da cafeína, acido ascórbico e ácidos graxos

Introdução: Pirose e regurgitação são manifestações da Doença do Refluxo Gastresofágico (DRGE) que ocorrem freqüentemente no terceiro trimestre da gravidez, porém seu impacto na qualidade de vida de gestantes é pouco conhecido. Objetivos: 1. Mensurar a qualidade de vida em gestantes no terceiro trimestre da gravidez com Pirose e Regurgitação; 2. Avaliar a relação entre Pirose e Regurgitação e a dieta. Pacientes e Métodos: Gestantes no terceiro trimestre acompanhadas ambulatorialmente foram entrevistadas para colher dados referentes à história obstétrica, freqüência, intensidade e passado de P e R, qualidade de vida (mensurada a partir do questionário genérico SF-36), ingestão alimentar (avaliada por recordatório de 24h) e medidas antropométricas; Resultados: Foram estudadas consecutivamente 82 gestantes: 62 com pirose e/ou regurgitação e 20 assintomáticas. Pirose foi relatada por 62 (76%) gestantes e regurgitação por 58 (71%). A idade gestacional média foi 33,8±3,7 semanas, 35 (43%) apresentavam história familiar positiva de pirose e/ou regurgitação e 57 (70%) não apresentavam tais sintomas fora da gravidez. Houve redução estatisticamente significativa na qualidade de vida das gestantes sintomáticas nos seguintes domínios: Para pirose, em Limitação Física e Aspectos Sociais; para regurgitação, em Limitação Física, Aspectos Sociais, Aspectos Emocionais e Dor. Houve concordância entre presença de pirose em gestações passadas e a atual. Gestantes com pirose apresentaram-se significativamente com maior peso corporal. Ácidos graxos poli e monoinsaturados, cafeína, ácido ascórbico e sulfato ferroso foram significativamente associados com pirose e/ou regurgitação. Conclusões: 1.Pirose e / ou regurgitação diminuíram a qualidade de vida em gestantes no terceiro trimestre; 2. ácidos graxos, cafeína, ácido ascórbico e sulfato ferroso estiveram associados com pirose e/ou regurgitação.

Study on functional cardiorespiratory changes after laparoscopic Nissen fundoplication

PURPOSE: To analyze the behavior of cardiopulmonary function in postoperative of laparoscopic Nissen fundoplication.METHODS: Thirty-two patients, 13 males (41%) and 19 females (59%), were evaluated. Their age ranged from 25 to 67 years, with a mean of 44.4 +/- 10.9. Pulmonary volumes, respiratory pressures and exercise tests were performed in the preoperative period (PRE) and in the first (PO1), second (PO2), fifth (PO5) and thirtieth (PO30) postoperative periods.RESULTS: Thirty-two patients were evaluated, of whom 59% were females. Mean age was 44.4 +/- 10.9 years. Lung volumes had significant decrease at PO1 and PO2 and were similar to PRE values at PO5. Respiratory pressures were altered only at PO1. The distance covered in the 6-minute walk test had significant reduction until PO2, and climbing time in the stair-climbing test significantly increased at PO2.CONCLUSION: Patients submitted to LNF surgery have decreased cardiorespiratory function in the early postoperative period; however, they soon return to preoperative conditions.
