BACKGROUND: Scleroderma or progressive systemic sclerosis is characterized by a chronic inflammatory process with proliferation of fibrous connective tissue and excessive deposition of collagen and extracellular matrix in the skin, smooth muscle, and viscera. The smooth muscle most involved in scleroderma is that of the esophagus, and dysphagia is the most commonly reported symptom. However, the internal anal sphincter may also be impaired by degeneration and fibrosis, leading to concomitant anal incontinence in scleroderma patients...

BACKGROUND: Gastroesophageal reflux disease (GERD) is a clinical condition that develops when the reflux of stomach contents causes troublesome symptoms and/or complications. Transient lower esophageal sphincter relaxation is the main pathophysiological mechanism of GERD. Symptoms and complications can be related to the reflux of gastric contents into the esophagus, oral cavity, larynx and/or the lung. Symptoms and other possible manifestations of GERD are heartburn, regurgitation, dysphagia, non-cardiac chest pain, chronic cough, chronic laryngitis, asthma and dental erosions...

BACKGROUND: Prolonged monitoring increased our knowledge on gastroesophageal reflux (GER), and the disease became known as gastroesophageal reflux disease (GERD). Prolonged reflux monitoring permits the diagnosis of GERD when endoscopic findings are not enough to characterize it. OBJECTIVE: The objective of this paper is to review the current knowledge on impedance-pH monitoring, taking into account the published literature and the authors experience with 1,200 exams...

BACKGROUND: Swallowing is a motor process with several discordances and a very difficult neurophysiological study. Maybe that is the reason for the scarcity of papers about it. OBJECTIVE: It is to describe the chewing neural control and oral bolus qualification. A review the cranial nerves involved with swallowing and their relationship with the brainstem, cerebellum, base nuclei and cortex was made. METHODS: From the reviewed literature including personal researches and new observations, a consistent and necessary revision of concepts was made, not rarely conflicting...

BACKGROUND: Acceptance of the prevailing pediatric Rome constipation criteria, by primary care physician, is still low. Even for research purposes they have not been universally adopted. Thus, it has been indicated that some re-evaluation of these criteria would be welcome. OBJECTIVE: The authors aimed to look at the timing of diagnosis and the dietary treatment recommendations in the criteria, to make proposals trying to approximate them to everyday practice. METHODS: The literature cited in the Rome criteria was reviewed and the publications pertinent to the subject, searched by Medline up to January 2018, were included...

BACKGROUND: Achalasia is a disease that affects esophageal bolus transit due to the absence of esophageal peristaltic contractions and impaired or absent relaxation of the lower esophageal sphincter. OBJECTIVE: The objective of this investigation was: a) to evaluate the dynamics of water ingestion in patients with achalasia, idiopathic or caused by Chagas' disease; b) to evaluate the influence of sex and age on water ingestion dynamics. METHODS: The investigation was conducted with 79 patients with achalasia (27 idiopathic and 52 Chagas' disease) and 91 healthy volunteers, all evaluated by the water-drinking test...

BACKGROUND: There is no a clear knowledge concerning the division of any part of the anal sphincter complex and the effect of this procedure on the function of the anal canal during the treatment of perianal fistula. OBJECTIVE: To evaluate the usefulness of 3D anorectal ultrasound in the assessment of anal fistula, quantifying the length of the sphincter muscle to be transected, selecting patients for different approaches and identifying healing, failure or recurrence after the surgical treatment...

BACKGROUND: Intestinal secretagogues have been tested for the treatment of chronic constipation and constipation-predominant irritable bowel syndrome. The class-effect of these type of drugs has not been studied. OBJECTIVE: To determine the efficacy and safety of intestinal secretagogues for the treatment of chronic constipation and constipation-predominant irritable bowel syndrome. METHODS: A computer-based search of papers from 1966 to September 2017 was performed...

BACKGROUND: Esophageal manometry is the most reliable method to evaluate esophageal motility. High resolution manometry (HRM) provides topographic contour colored plots (Clouse Plots) with simultaneous analysis from the pharynx to the stomach. Both solid state and water-perfused systems are available. OBJECTIVE: This study aims to determinate the normative data for a new water-perfused HRM. METHODS: HRM was made in 32 healthy volunteers after 8 hours fasting...

Gastroesophageal reflux disease (GERD) is the most common disease of the upper gastrointestinal tract in the Western world. GERD pathophysiology is multifactorial. Different mechanisms may contribute to GERD including an increase in the transdiaphragmatic pressure gradient (TPG). The pathophysiology of GERD linked to TPG is not entirely understood. This review shows that TPG is an important contributor to GERD even when an intact esophagogastric barrier is present in the setting of obesity and pulmonary diseases...

BACKGROUND: High resolution anorectal manometry (HRAM-WP) allows more simplified, objective, and uniform data acquisition and interpretation of the test results. OBJECTIVE: To validate a HRAM under water perfusion (Alacer Biomédica) with a 24-channel probe and to compare the results of anorectal manometry with other systems. METHODS: Individuals without critical evacuation disorders were selected. Patients with incontinence, anal surgery, dyssynergia or sphincter injury were excluded...

Acute kidney injury is a common complication of cirrhosis, occurring in up to 20% of patients hospitalized with cirrhosis. This field is rapidly changing, with significant advances in classification, biomarkers and therapy over the last few years. On the behalf of the Brazilian Society of Hepatology, a panel of experts in Hepatology and Nephrology reviewed published evidence to integrate findings and develop the recommendations presented in this manuscript.

BACKGROUND: Several epidemiological studies have investigated the association of promoter region polymorphisms of Interleukin-10 (IL-10) gene with colorectal cancer (CRC), while the conclusion is still conflicting and inconclusive. OBJECTIVE: We conducted this meta-analysis to evaluate the association of promoter region polymorphisms of IL-10 with CRC. METHODS: Eligible articles were identified by a search of several bibliographic databases for the period up to March 15, 2018...

BACKGROUND: Endoscopic antireflux treatments for gastroesophageal reflux disease (GERD) are still evolving, and most of the published studies address symptom relief in the short-term. Objective - We aimed to perform a systematic review and meta-analysis focused on evaluating the efficacy of the different endoscopic procedures. METHODS: Search was restricted to randomized controlled trials (RCTs) on MedLine, Cochrane, SciELO, and EMBASE for patients with chronic GERD (>6 months), over 18 years old and available follow up of at least 3 months...
