Eventos adversos en una nueva unidad de cuidados intensivos. Influencia del diseño y la tecnología de las instalaciones en las tasas de incidencia.
New hospitals are replacing old facilities. There is little information on the performance of an intensive care unit (ICU) when it is relocated in a new and equipped area. ⋯ In comparison with the f-ICU, most of the monitored adverse events did not significantly change within the first 18 months of activities at the n-ICU.

"The books and the night", neurological perspective on Jorge Luis Borges' blindness.
The works of Argentinian scholar Jorge Luis Borges (1899-1986) have captivated physicians. An assiduous reader, he was given, with magnificent irony, "books and the night". Borges suffered from chronic and irreversible blindness, which influenced much of his work and has been the subject of different literary and diagnostic analyses from the ophthalmological point of view. ⋯ On his autobiography, he recounts how, during an episode of septicemia, he suffered hallucinations and loss of speech; in addition, in some poems and essays he describes data that suggest "phantom chromatopsia", a lesion of cortical origin. After that accident, Borges survived with a radical change in literary style. Although a precise diagnosis is impossible, his literary work allows recognizing some elements in favor of concomitant brain involvement.

A clinical research question requires the concurrence of clinical experience and knowledge on methodology and statistics in that who formulates it. Initially, a research question should have a structure that clearly establishes what is that which is being sought (consequence or outcome), in whom (baseline status), and by action of what (maneuver). Subsequently, its reasoning must explore four aspects: feasibility and reasonableness of the questioning, lack of a prior answer, relevance of the answer to be obtained, and applicability. ⋯ One should never forget that every maneuver entails adverse events that, when serious, discredit good results. It is imperative to have the possible answer estimated from within the structure of the question. The function of clinical research is to corroborate or reject a hypothesis, rather than to empirically test to find out what the outcome is.

The first draft of the human genome sequencing published in 2001 reported a large number of single nucleotide polymorphisms (SNPs). Given that these polymorphisms could practically represent all the variability involved in the susceptibility, protection, severity, among other aspects, of various common diseases, as well as in their response to medications, it was thought that they might be "the biomarkers of choice" in personalized genomic medicine. ⋯ The use of these markers has served to identify regions of the genome involved in Mendelian diseases (one gene-one disease) or genes directly associated with multifactorial diseases. This review has the purpose to describe the role of STRs, VNTRs, SNPs, CNVs and INDELs in linkage and association studies and their role in Mendelian and multifactorial diseases.

Neuropathic pain is an entity that causes patient disability and its diagnosis and treatment is a challenge for physicians. In a significant percentage of patients with neuropathic pain, it is restricted to one dermatome or to a particular region of the body; in this case, it is referred to as localized neuropathic pain. There are no Mexican clinical guidelines proposing recommendations for the diagnosis and treatment of localized neuropathic pain in our population. This article presents the recommendations of a multidisciplinary consensus of specialists from different areas involved in the diagnosis and treatment of this type of patients.
