Independent inter and intra-observer agreement of the Schizas's classification of degenerative lumbar stenosis: Comparison among three levels of surgical training.

Introduction And Objectives: Lumbar spinal stenosis is a common age-related condition that affects the quality of life. Multiple classifications have been developed to quantify the severity of stenosis affecting comparison between studies and homogenous communication among surgeons and researchers. Even though this classification has not shown a direct clinical correlation, Schizas's classification appears to be a simple method to assess stenosis.

Bilateral Radioscopically Guided Erector Spinae Plane Block for Postoperative Analgesia in Spine Surgery: A Randomized Clinical Trial.

Background:  We compare two perioperative pain management procedures(a radioscopicallyguided erector spinae plane [ESP] block versus the standard wound infiltration technique with local anesthetics) in patients undergoing lumbosacral spine surgery.

Methods:  A randomized, double-blind clinical trial was performed, in which adults at our hospital undergoing lumbosacral surgery without fixation were randomly assigned to receive either the standard wound infiltration technique, employing long-term anesthetics, or a radioscopicallyguided ESP block. Postoperative pain severity, morphine consumption, number of patients immobilized due to wound pain, length of hospitalization, and complications were recorded.

[Agenda 2030 in Argentina: perceptions of health experts, comparison with the perceptions of Brazilian experts and the first impacts of the COVID-19 Pandemic].

The 2030 Agenda - a strategy of the United Nations Organization (UN) to promote global and sustainable human development capable of satisfying basic social needs - is still in the initial stages in most of the countries of South America. The scope of this investigation was to consult a group of health experts on the possibilities of Argentina fulfilling the 2030 Agenda, especially the goals of ODS3 - Health and Wellbeing - when they were consulted on obstacles, challenges, and policy recommendations to meet the goals. The change of management of the government in December 2019, and the outbreak of the Covid-19 pandemic in 2020, broadened the investigation incorporating the analysis of the incumbent Minister of Health of the Nation on the 2030 Agenda, the study carried out and the current perspectives in the pandemic period.

Relationship between the posterior septal artery and the upper edge of the choana.

Background: The pedicled nasoseptal flap has been a key element in advancing the endoscopic transnasal approach (ETA) for the treatment of skull base lesions from the anterior cranial fossa to the occipitocervical junction. To preserve vascular supply, an anatomical knowledge of the location of the posterior septal artery (PSA) is essential. The objective of this work is to establish the relationship between PSA and the superior edge of the choana to define a safety margin during the opening of the sphenoidal rostrum preserving PSA.
