Lacrimal stenting versus three-snip punctoplasty for treatment of punctal stenosis or occlusion: an open- label, randomized clinical trial.

Background: To compare the short-term anatomical and functional outcomes of, as well as patient satisfaction with, lacrimal stenting and three-snip punctoplasty for the treatment of punctal stenosis or occlusion.

Methods: In this open-label, randomized clinical trial, we included 50 eyes of 30 patients diagnosed with punctal stenosis or occlusion. They were randomly allocated to two groups of 25 eyes each, using central telephone randomization.

[Oxidative stress; a comparative study between normal and morbid obesity group population].

Objective: To determine the level of oxidative stress in morbid obese patients by comparing their results to those of a normal population.

Material And Methods: We have studied the metabolites most representative of OS, both in the blood (MDA, 8-oxo-dG, GSSG and the ratio GSSG/GSH) and in the urine (8-oxo-dG), as well as the GSH antioxidant. A descriptive analysis of the sample was performed.

[Local treatment of a chronic anal fissure with diltiazem vs. nitroglycerin. A comparative study].

Aim: To assess the value of using smooth muscle relaxants drugs and assess the results of the topical use of 2% diltiazem as an alternative to 0.2% nitroglycerin in the treatment of chronic anal fissure (CAF).

Methods: Review of the CAF contained in a prospectively collected database of anal fissures including one hundred forty-five patients diagnosed with CAF and treated with standard measures (ST) in two consecutive periods.
