Prolonged Computer Use by Office Workers Induces Ocular Symptoms Associated With Tear Film Alterations and Overexpression of Mucin 5 AC and Catalase.

Objective: The aim of the study was to evaluate office workers for symptoms of computer vision syndrome (CVS) and alterations in the tear film relate to the hours of daily computer use.

Methods: Sixty-seven volunteers were divided into 2 groups: 2 to 6 and 7 to 12 hours of daily computer use. Computer vision syndrome symptoms, tear film stability by tear film break-up time test, and composition of mucin 5 AC, catalase, and IL-6 was assessed by relative gene expression of conjunctival impression cytology samples were examined.

[Intestinal obstruction secondary to postoperative adhesion formation in abdominal surgery. Review].

The development of intestinal obstruction after upper and lower abdominal surgery is part of the daily life of each every surgeon. Despite this, there are very few good quality studies that allow enable assessment of the frequency of intestinal obstruction to be assessed, even although postoperative adhesions are the cause of considerable direct and indirect morbidity and its prevention can be considered a public health problem. And yet, in Mexico, at this time, there is no validated recommendation validated on the prevention of adhesions, or more particularly, in connection with the use of a variety of anti-adhesion commercial products which have been marketed for at least a decade.
