Hemoglobin S is an abnormal protein that induces morphological changes in erythrocyte in low-oxygen conditions. In Mexico, it is reported that up to 13.7% of the population with mutation in one allele are considered asymptomatic (sickle cell trait). The sickle cell trait and diabetes mellitus are conditions that occur together in more than one million patients worldwide. ⋯ We found that older men with diabetes were susceptible to generate sickle cells and this correlated with reduced red blood cell count and an increase in media cell volume. In samples of women diabetes, there were no differences. We conclude that samples from patients with sickle cell trait and diabetes can cause sickle cells with high frequency in men, with lower red blood cells count and increased mean corpuscular volume as susceptibility parameters.

Observational Study
[Diagnostic utility of the hyomental distance ratio as predictor of difficult intubation at UMAE 25].
The hyomental distance ratio is defined as the ratio of the hyomental distances in neutral position and at head extension. The aim of the study was to establish the diagnostic utility as predictor of difficult intubation. ⋯ The hyomental distance ratio, as predictor of difficult intubation, has little utility.

This report describes a solution for a restenosis and for the fracture of a stent in the vertebral artery in a patient suffering from vertebrobasilar symptoms. Angiography demonstrates restenosis of a vertebral stent as well as its fracture and migration into the subclavian artery. ⋯ Pre-dilatation and kissing balloon techniques were applied in both the vertebral and subclavian arteries to modify the stent's dimensions and shape it into the form of a "ring." Postprocedural angiography demonstrated an excellent final result with the assistance of StentBoost visualization. Control angiography at six months also utilized StentBoost imaging and confirmed the patency of the bifurcation and that the stent was not displaced.

Historical Article
[The journey of the vaccine against smallpox: one expedition, two oceans, three continents, and thousands of children].
Spain encouraged, during the Bourbon dynasty, the formation of scientific expeditions, among which was the Royal Philanthropic Vaccine Expedition, an example of biopolitics applied by the state in order to protect health. The expedition went all over the world, using children as a reservoir to transport the vaccine fluid. Francisco Xavier Balmis established a human chain that arm-to-arm materialized the success of the mission. The characteristics and difficulties which children had to pass through and their contribution to the spread of the smallpox vaccine are analyzed.

Comparative Study
[Depression in school children and adolescents carriers of acute leukemia during the treatment phase].
Objective: To describe depression levels in school aged children and adolescents with acute leukemia during the treatment. ⋯ We found a high percentage of severe level depression, which affected mostly male patients, suffering a relapse during the consolidation treatment phase.
