Subsequently, a positive or negative GER diagnosis was established based on the results given by impedance measurement analysis as compared with the diagnostic results from pH-testing.

The alkaline and mildly-acidic refluxes not detected by pH-monitoring constitute a high percentage of events. PH monitoring in the distal and proximal esophagus in symptomatic infants.

Thirty nine patients were evaluated over this 3 year period. Se continuar a navegar, consideramos que aceita o seu uso. SNIP measures contextual citation impact by wighting citations based on the total number of citations in a subject field. There also remains a group of infants classified under “without identifiable cause” whom have the highest tendency for sudden death, oscillating between 0. Czinn SJ, Blanchard S. Print Send to a friend Export reference Mendeley Statistics. But, diverse studies show that a large number of infants admitted to the emergency room for ALTE have alterations in at least one parameter of the pH-test 10which, however, could lead us to over-diagnose GER as the principle cause Subscriber If you already have your login data, please click here.

An Pediatr Barc ; Twenty-four hour ambulatory simultaneous impedance and pH monitoring: Esophagic multichannel intraluminal impedance. Rate and characteristics of acid, weakly acidic, and weakly alkaline gastroesophageal reflux.

A retrospective study was done for MII-pH-testing between September and December on infants less than one year old admitted under our care on the hospital floor for having presented an apparent life threatening disorder.

Clin Gastroenterol Hepatol ;4: Pediatric gastroesophageal reflux clinical practice guidelines: This could be of diagnostic and therapeutic importance 25especially in younger infants at risk of esophageal disease not associated with acids. Various techniques have been used to categorize reflux, allowing us to measure and assess the underlying problem -the exposition time of the esophagus to gastric juices.


For the study of statistical associations a simple or bivariate analysis was used. Additionally the reproducibility of the MII-pH-testing data is relatively poor in children There is a statistically-significant relationship when applying the chi-squared test p 0. However, this is all very tentative due to the lack of normal standards for this age group when using MII. Thus, it is possible to complete the study of GER, thereby permitting the classification of acidic or non-acidic episodes an average of 58 mildly-acidic or non-acidic refluxes were detected per patientdefining the relationship between atypical symptoms and each type of episode, characterizing the type of material refluxed in liquid, gas or mixed form, and determining the ascension height and the clearing time 12,13much greater in the middle and lower thirds than is detectable with pH-testing this is evident in table I and justified by the possibility that the bolus persists in the esophagus but with a progressive increase in pH.

Studies are still necessary to evaluate the normal standards for MII in pediatric patients. Are you a health professional able to prescribe or dispense drugs? The software used incorporated automatic analysis of the entries and easy-to-read and easy-to-interpret readouts.

Multichannel intraluminal impedance MII -pH-testing could prove advantageous in the detection of acid reflux and non-acid reflux, the clearing times for these and the esofaigca distances up the esophagus.

Objectives The objective of this work is a description of the epidemiological and clinical data from infants admitted for ALTE and subjected to MII-pH-testing over the study period and the comparison of those results obtained via these two methods determining the sensitivity and the specificity of each one. There was an average of 75 IQ: Gastroesophageal reflux disease in neonates and infants: Normal values and day-to-day variability of h ambulatory oesophageal impedance-pH monitoring in a Belgian-French cohort of healthy subjects.

The relation im;edanciometria MII and pH-testing, in addition to providing ezofagica about non-acid refluxes, non-liquid refluxes and the distance traveled by the bolus, gives information about improving the efficiency of the diagnosis without submitting the ipedanciometria to any additional risks. Epidemiology and pathophysiology of symptomatic gastroesophageal reflux disease.

Am J Gastroenterol ;98 3 Supl. Mediante IIM se registraron 8. Further studies are needed to assess the normality of MMI in pediatric patients. Given that pH-testing is considered to be the golden standard for defining the GER pathology, the parameters considered from the start to be labeled as “classic” include the following: However, it is conceivable that there should be a cause for all infants presenting ALTE, even if sometimes we cannot define it. Intraluminal impedance technique in the diagnosis of apparent life-threatening events ALTE.

In the same way, the combination of pH-testing and MII uses its individual channels to help characterize refluxed materials liquids, gases and mixed and the distance that the bolus travels in the esophagus.

You can change the settings or obtain more information by clicking here. October Pages However, multichannel intraluminal impedance MII may provide advantages. The location of the electrode tip was determined using the Strobel formula 0.

SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal’s impact. Acids during gastro-esophageal reflux GER have been considered the main cause for gastro-esophageal reflux disease GERD in infants 1a disease which manifests with digestive and extra-gastrointestinal symptoms such as apnea and apparent life threatening episodes ALTE 2.

Textbook of Clinical Pediatrics.

Based on the area under the curve, values can be interpreted giving 0. The correlation between these variables impedznciometria analyzed using Spearman tests and their relation to each other using Cramer’s V and the phi coefficient. The combination of MII with monitoring using pH-testing allows for diagnosing the existence of alkaline reflux and moderately-acidic refluxes, thus improving upon this limitation presented in the field of conventional pH-testing.
