MSH-5: malignant knee tumors timely detection index.

Background: Bone neoplasms are usually misdiagnosed causing a delay in their treatment. Bone neoplasms are usually confused with tendinitis, 31% of the cases corresponds to osteosarcomas and in 21% to Ewing's sarcomas.

Objective: To create a clinical-radiographic instrument of high diagnostic suspicion of knee bone neoplasms to prevent a delay in diagnosis.

Quality of life related to both general and oral health two years after treatment for subcondylar fracture.

The success of treatment for condylar fractures is usually assessed by functional outcomes, while studies on patient perceptions are scarce. A cross-sectional study was performed to assess the middle-term quality of life, related to both general health and oral health, of patients treated for subcondylar fracture, either by open reduction or by closed fixation, compared to healthy volunteers. In a single trauma centre, among 226 consecutive patients with subcondylar fractures that were treated in years 2018-2019 (two to three years prior to the survey), 148 fulfilled the selection criteria.

A Novel Technique for the Evaluation and Interpretation of Elastography in Salivary Gland Involvement in Primary Sjögren Syndrome.

Ultrasound (US) of major salivary glands (MSG) evaluates echogenicity, border features and vascularization, with elastography, it can detect tissue elasticity and glandular fibrosis, related to inflammation in Primary Sjögren's syndrome (pSS). This study aimed to develop a novel technique by pixel analysis for evaluation and interpretation of elastography in MSG in pSS. A cross-sectional and observational multicenter study was conducted.

Influence of Work Hardening on the Surface of Backup Rolls for a 4-High Rolling Mill Fractured during Rolling Campaign.

Backup rolls are the main tool in a four-high rolling mill; the rolling forces applied in load cells promote the fatigue of the material due to mechanical contact between backup rolls and work rolls. This work investigated the causes of recurrent failures in backup rolls, with cracking always initiated on the surface of the roll body and finishing in the main radius between neck and roll body. Aiming to find the causes of failure, visual inspection and morphology of the fracture were performed, complemented with mechanical tests of hardness on the stress concentration area, in addition to validating the results by applying the finite element method, using ANSYS Mechanical Static Structural Software.

MESS has demonstrated functional and prognostic association.

[Evaluation of the educational intervention in orthopaedic and traumatology residents for the taking, measurement and preparations of the hamstring graft].

Introduction: The education process is understood as an activity focused on developing competencies through the use of educational tools and strategies that can be evaluated. The training of the residents in traumatology and orthopedics requires you to acquire knowledge and develop skills that will affect the diagnosis, treatment and prognosis of the patient. Therefore, what will be the evaluation of the educational intervention on the theoretical and practical knowledge in this group of physicians on the technique of taking, measuring and preparation of hamstring graft for the reconstruction of anterior cruciate ligament?

Material Y Methods: A prospective, quasi-experimental study was conducted to evaluate the impact of educational intervention in 23 Traumatology and orthopaedic residents on the use of hamstring in the anterior cruciate ligament reconstruction through theoretical sessions and Practice on cadaverous knees with preand post-intervention evaluations.

High Serum Levels of High-Mobility Group Box 1 (HMGB1) and Low Levels of Heat Shock Protein 70 (Hsp70) are Associated with Poor Prognosis in Patients with Acute Pancreatitis.

Introduction: Cell damage in Acute Pancreatitis (AP) lead to release of cytokines and HMGB1 and Hsp70. While Hsp70 plays a role in cytoprotection, when released to extracellular milieu constitutes, as HMGB1, a danger signal and trigger pro-inflammatory responses. These molecules seem to be related to the clinical progression; but because no evidence exists about them as molecular network in AP development, we quantify HSP70, HMGB1, and cytokines in patients with AP and search for correlations with severity and prognosis.

[Leucocyte esterase as a reliable diagnostic, cost-effective and fast in knee infections].

Background: The articular infection represents a challenge due to its complexity and its devastating effect when not treated promptly. We have various diagnostic studies: cultures, ESR, CRP, count of leukocytes, among others but none is specific, it takes more than 30 minutes to complete and require complex infrastructure. In this study we determine the sensitivity and specificity of the leukocyte esterase for detection of an infectious process joint in Mexican population.

Preoperative serum albumin as a predictor of complications following total hip replacement in patients with rheumatoid arthritis.

Background: Rheumatoid arthritis is a chronic inflammatory disease characterized by polyarthritis with progressive articular wear, immunologic abnormalities and increasing physical limitation. Surgical correction with hip replacement comes as a successful solution for patients with advanced articular destruction. Following intervention, surgical site infection (SSI), venous thromboembolism, sepsis, renal and major cardiovascular complications are among the most cited in the literature.

A prospective randomized trial of total synovectomy versus limited synovectomy in primary total knee arthroplasty: evaluation of bleeding, postoperative pain, and quality of life with SF-12 v2.

Background: During total knee arthroplasty (TKA), total synovectomy (TS) as a part of the surgical technique has been proposed to reduce the inflammatory tissue after the procedure, but there is a controversy about it because of the risk of major postsurgical bleeding. The aim of this study was to compare postoperative bleeding, pain, and health-related quality of life (HRQOL) after a TKA when a TS is performed and when it is not.

Methods: The difference in pre and postoperative hemoglobin was measured, as well as postoperative pain using visual analogue scale (VAS) scores at 24 and 48 h post-surgical, HRQOL was measured prior to surgery and at one year using the SF-12V2 questionnaire.

Serum substance P: an indicator of disease activity and subclinical inflammation in rheumatoid arthritis.

The aim of the is study is to examine the role of serum substance P (SP) levels as a simple biomarker for rheumatoid arthritis (RA) disease activity, its correlation with other markers of disease activity, and with selected clinical parameters. The study comprised 90 RA patients and 24 healthy controls. RA activity was assessed by means of the disease activity 28-C-reactive protein (DAS28-CRP) index and ultrasound power Doppler (USPD) by the German ultrasound score based on seven joints.

Background: Articular infection is an orthopedic challenge due to its difficult diagnosis and devastating results. Various diagnostic studies exist: culture, ESR, CRP, count of leukocytes, among others, but none is specific, they all take more than 30 minutes to complete, and require complex infrastructure. In this study, we determine the sensitivity and specificity of the leukocyte esterase for detection of an infectious process joint in Mexican population.
