Milton Melciades Barbosa Costa
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.

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...

Janus kinases inhibitors have already been incorporated into the management of immune-mediated diseases, such as rheumatoid arthritis, and are being investigated for the treatment of psoriasis and inflammatory bowel diseases, both ulcerative colitis and Crohn's disease. Tofacitinib is an oral small-molecule drug that inhibits Janus kinases 1, Janus kinases 3, and, to a lesser extent, Janus kinases 2. This inhibition ends up blocking signals for several inflammatory cytokines that are involved in the pathogenesis of inflammatory bowel diseases and play a role in many immune signaling routes, including lymphocyte activation, function, and proliferation...

BACKGROUND: Infliximab (IFX) therapeutic drug monitoring is an important tool to guide therapeutic decision in inflammatory bowel disease patients. Currently, there are two methods to measure trough levels of IFX, ELISA assays or rapid tests. Despite that the ELISA assay is the most used method in therapeutic drug monitoring, the results take long to be available for clinical use, and it needs to be performed by trained personnel. In contrary, the results of a rapid test take 20 to 30 minutes to be available and can be performed by non-trained lab personnel...

BACKGROUND: Inflammatory bowel disease is a systemic inflammatory disease classified as Crohn disease or ulcerative colitis. It could present extra intestinal findings, such as fever, weight loss, arthralgia, mucocutaneous lesions, hepatic, renal and ophthalmological involvement. Among ophthalmological findings, posterior segment findings are present in less than 1% of patients with inflammatory bowel disease, however, these findings could bring definitive visual impairment. OBJECTIVE: Our study objective was to evaluate ocular posterior segment findings is patients with inflammatory bowel disease, through retinal mapping, color fundus retinography, optical coherence tomography (OCT) and OCT angiography, and compare our results to literature...

BACKGROUND: The interaction between serum lipids and C virus infection is well known, as are serum lipid levels in the Peg-IFN / RBV-based treatment. However, with direct action antivirals (DAAs) this behavior is still unclear. OBJECTIVE: To compare serum lipids levels between patients treated with Peg-IFN/RBV and DAAs and to evaluate lipids in sustained virological response (SVR) with DAAs. METHODS: Retro prospective study comparing the behavior of total cholesterol (TC), low-density lipoprotein (LDL) and triglycerides (TG) serum levels during treatment with DAAs (G-DAAs) and a control historic group Peg-IFN/RBV (G-PR)...

BACKGROUND: Insulin resistance and diabetes mellitus are common extrahepatic manifestations of chronic hepatitis C (HCV). Insulin resistance assessed by HOMA-IR is associated with low rates of sustained virological response, especially in HCV genotype 1 positive patients treated with peginterferon/ribavirin. The effect of insulin resistance on sustained virologic response in HCV genotype 3 positive patients who were treated with peginterferon/ribavirin still remains unclear. OBJECTIVE: To evaluate the impact of insulin resistance on sustained virological response in HCV genotype 3 patients treated with peginterferon/ribavirin...

BACKGROUND: Familial Mediterranean fever and celiac disease share some common clinical features such as abdominal pain, diarrhea, arthralgia and arthritis. Also, both of the diseases are associated with many inflammatory and autoimmune diseases. Previous studies have shown the association between familial Mediterranean fever (FMF) and different clinical conditions. OBJECTIVE: We aimed to investigate the relationship between celiac disease and colchicine-resistant familial Mediterranean fever (crFMF) disease...

BACKGROUND: Schistosomiasis is an endemic health problem affecting about four million people. The hepatosplenic form of the disease is characterized by periportal hepatic fibrosis, pre-sinusoidal portal hypertension and splenomegaly. Liver function is preserved, being varices bleeding the main complication of the disease. The surgical treatment used in the majority of centers for the prevention of rebleeding is esophagogastric devascularization and splenectomy. Most authors reported better results with the association of surgical and postoperative endoscopic treatment...
