Rotator Interval vs Posterior Approach Ultrasound-guided Corticosteroid Injections in Primary Frozen Shoulder: A Meta-analysis of Randomized Controlled Trials.

Objective: To compare the efficacy of rotator interval (RI) vs posterior approach (PA) ultrasound (US) guided corticosteroid injections into the glenohumeral (GH) joint in primary frozen shoulder (PFS).

Data Sources: A systematic literature search for all relevant studies on Medline, Scopus, Embase, Web of Science, and Cochrane Central, up to January 2023 was conducted.

Study Selection: Randomized controlled trials that directly compared the US-guided corticosteroid injection into the RI and GH joint using PA in patients clinically and radiographically diagnosed with PFS.

Assessment of burnout syndrome and associated factors among medical students during the COVID-19 pandemic.

Overwhelming requirements, a high degree of work, and prolonged exposure to emotionally demanding circumstances in work and life settings can lead to burnout syndrome. The purpose of the study is to assess burnout syndrome and its associated factors among medical students during the COVID-19 pandemic. A cross-sectional, prospective, descriptive study was conducted in a Mexican medical school during the last week of the spring semester of 2021 using the Maslach Burnout Inventory-Student Survey (MBI-SS) and an associated factors survey.

Payment with knowledge: A method for a training of anatomy near-peer teachers and formation of future anatomists.

Near-peer teaching has been widely implemented in medical schools and the benefits for the near-peer teachers (NPTs), the students, and the institution have been well documented. However, NPT training methods and perceptions of such have been limited. A four-year clinical anatomy and surgical training program was established (est.

In Vivo Models for the Study of Hyaluronic Acid Fillers: A Review.

Background: Hyaluronic acid (HA) filler application is one of the most frequent minimally invasive aesthetic procedures used worldwide. Its properties and characterization, performance, effects in other tissues, and response to complication treatments have been studied in several animal models. This review aims to categorize animal models considering the advantages and disadvantages regarding the purpose of the study.

Trendelenburg (Head-Down tilt) and head rotation: Ultrasonographic effects on the internal jugular vein for catheterization safety.

Most guidelines fail to specify patient positioning during central venous catheterization. The objective was to determine the effects of head-down tilt (Trendelenburg position) and head rotation on the internal jugular vein (IJV). A prospective, observational, longitudinal, and descriptive study using healthy adult volunteers, of both sexes, was performed.

Hyaluronic Acid Embolism Treated with Subcutaneous High and Low Hyaluronidase Doses: Efficacy and Surrounding Tissue Effect.

Background: The use of hyaluronidase in hyaluronic acid vascular occlusion has been evaluated; however, the models used do not accurately assimilate the facial morphologic characteristics or study the effects on adjacent tissues. The purpose of this study was to determine an effective concentration of subcutaneous hyaluronidase to dissolve a hyaluronic acid embolism and its effect on surrounding tissue.

Methods: Fifteen rabbits were divided into six groups.

Localized gallbladder perforation: a systematic review of treatment and prognosis.

Background: The optimal management of localized gallbladder perforation (Neimeier type II) has yet to be defined. The aim of this systematic review was to identify factors associated with improved patient outcomes.

Methods: Systematic review of studies that described the management of Neimeier type II perforation, reported complications of the first intervention, necessity of added interventions, resolution of the pathology, and days of hospital stay were included.

Comparison of suturing models: the effect on perception of basic surgical skills.

Background: Acquisition of Basic Surgical Skills (BSS) are essential for medical students. The objective was to determine it's fidelity impact.

Methods: Using four suturing models (SM) (pigskin, sponge, commercial pad, and orange), SM-quality and student-SM interaction were evaluated.

Mexican Educators Survey on Anatomical Sciences Education and a Review of World Tendencies.

Anatomical sciences curricula have been under constant reform over the years, with many countries having to reduce course hours while trying to preserve laboratory time. In Mexico, schools have historically been autonomous and unregulated, and data regarding structure and methods are still lacking. A national survey was sent by the Mexican Society of Anatomy to 110 anatomical sciences educators.

Collaborative mentoring for effective medical research groups.

This article was migrated. The article was marked as recommended. Research benefits professors and students, mentors and mentees, however, many Universities lack formal programs, especially in basic sciences such as anatomy.
