IMPACT OF MEASURES TO FIGHT THE PANDEMIC COVID-19 ON KNEE ARTHROPLASTIES IN BRAZIL.

Objective: To assess the impacts of measures to face COVID-19 on total knee arthroplasty procedures in the country, based on data provided by the SUS Information and Informatics Department (DATASUS).

Methods: Cross-sectional study of secondary data in the public domain, available on the website of the Department of Information and Informatics of SUS (DATASUS), containing information about hospital admissions in the SUS.

Results: Brazil suffered a 51.

COMPARISON OF HEMOSTASIS WITH TRANEXAMIC ACID IN TOTAL KNEE ARTHROPLASTY.

Objective: To compare the use of intravenous and topical tranexamic acid (TXA) in unilateral primary total knee arthroplasty (TKA) in relation to blood loss and complications inherent to the medication.

Method: Three groups with 14 patients each were constituted, and all of them were operated using the same surgical technique. In Group 1, usual measures for bleeding control were performed.

Association of the polymorphism Exon 1 (A/O) region of the mannose-binding lectin gene and periportal fibrosis regression in schistosomiasis after specific treatment.

Introduction: We evaluated the association between genetic polymorphisms in exon 1 (A/O alleles) and promoter regions at positions -550 (H/L variant, rs11003125) and -221 (X/Y variant, rs7096206) MBL2 and periportal fibrosis regression.

Methods: This was a retrospective cohort study involving 114 Brazilians infected with Schistosoma mansoni, who were subjected to follow-up for three years after specific treatment for schistosomiasis to estimate the probability of periportal fibrosis regression.

Results: A risk association was observed between polymorphism at the exon 1 MBL2 and periportal fibrosis regression.

Intrapelvic Migration of the Cephalic Screw of a Proximal Femoral Long Intramedullary Nail: Case Report.

The use of cephalomedullary devices has gained popularity in the treatment of proximal femoral fractures. Despite their biomechanical advantages, several complications are well described in the literature. One of these complications, which is rarely reported, is the medial migration of the cephalic screw.

PARSONAGE-TURNER SYNDROME: CASE REPORT OF A HIV-SEROPOSITIVE PATIENT.

The etiology is uncertain, but it is believed that infectious and autoimmune factors are involved. The diagnosis is made by exclusion, and the main differential diagnoses are cervical disc hernias, rotator cuff injuries and rheumatic diseases.
