[Bibliometric analysis of scientific output on influenza in Mexico, 2000-2012].

Background: During the spring of 2009, H1N1 influenza became the first pandemic of the 21st century. There are no bibliometric studies in Mexico that have analyzed this topic in relation to the generation of Mexican knowledge. The aim of this article is to determine the volume and impact of Mexican scientific output published in journals indexed in Science Citation Index (SCI) on influenza from January 1, 2000, to October 1, 2012.

Quantifying the mortality caused by the H1N1 influenza virus during the 2009 pandemic in Mexico.

Introduction: The frequency and mortality of the pandemic caused by influenza A(H1N1)pdm09 might have been underestimated, especially in developing countries. This study was designed to quantify the possible underestimation of pandemic influenza mortality and evaluate the concordance between the data reported for A(H1N1)pdm09 mortality and the causes of death reported during the pandemic period of April 2009 to February 2010.

Methodology: The death certificates of 754 confirmed cases of A(H1N1)pdm09 infection were included in the study.

[Mechanical ventilation parameters associated to barotrauma in a neonatal intensive care unit].

Objective: To identify the parameters of mechanical ventilation related to barotrauma and to identify associated diseases.

Material And Methods: There was a partial retrospective study which included all the files and/or newborns (NB) who were in the Neonatal Intensive Care Unit during March 2003 to April 2008 met the inclusion criteria. Two groups were conformed, the group A, cases (those with barotrauma) and B controls (that did not show it).

[Predictors factors for the extubation failure in two or more times among preterm newborn].

Introduction: With the ventilatory mechanical attendance has been prolonged the life of the preterm newborn (PTNB) critically sick and during that lapse many occasions it is necessary reintubation to PTNB in two or more times with the subsequent damage that makes enter to the patient to a vicious circle with more damage during the same reintubated. The objective of this study was to determine the factors that predict the extubation failure among PTNB from 28 to 36 weeks of gestational age in two or more times.

Material And Methods: It was considered extubation failure when in the first 72 hours of being had extubated the patient; there was reintubation necessity, independent of the cause that originated it.
