Superior Capsular Reconstruction of the Shoulder with Long Head of Biceps Autograft vs. Achilles Tendon Allograft: A 2-Year Comparative Study.

Purpose: To retrospectively evaluate the clinical-functional outcomes, healing rates, complications, and surgical time in patients treated with superior capsular reconstruction (SCR) using long head of the biceps autograft (LHB) and Achilles allograft (AA).

Materials And Methods: This retrospective study included 24 patients with irreparable rotator cuff tears of the supraspinatus and infraspinatus, treated with SCR. Two treatment groups were formed: one with 12 cases using AA and another with 12 cases using LHB.

Shoulder injury related to vaccine administration following SARS-CoV-2 inoculation: Case series and review of literature.

Introduction: Shoulder Injuries Related to Vaccine Administration (SIRVA), describes those cases of shoulder severe post-inoculation complications, including pain and prolonged disability. Most of the reported cases have been secondary to influenza vaccination. This study retrospectively describes a series of 18 patients following SARS-CoV-2 inoculation and compares the findings with those previously reported for other vaccines.

Shoulder Injury Related to Vaccine Administration Following Misplaced SARS-CoV-2 Vaccination: A Case Report and Review of Literature.

Introduction: To confront the SARS-CoV-2 pandemic, a large share of the population must be immunized. Intramuscular vaccination of the shoulder is the preferred technique as it is easily exposed and guarantees a good immune reaction. Local side effects, such as pain and swelling, are common after deltoid inoculation.

[A population-based study on seroprevalence and factors associated with SARS-CoV-2 infection in Córdoba, Argentina].

Seroepidemiological studies help identify the indirect distribution of diseases, detecting serological markers of immunity and demonstrating undiagnosed infections in the general population. The objectives were to estimate the seroprevalence of SARS-CoV-2 antibodies in Córdoba, Argentina, from December 2020 to January 2021 and to identify factors associated with the virus' contagiousness. A population-based cross-sectional observational study was performed in 3,225 individuals over two years of age living in Córdoba city, selected by multiple-stage random sampling proportional to distribution by gender, age group, and socioeconomic status in the city's population.

Relevance of HTLV-1 proviral load in asymptomatic and symptomatic patients living in endemic and non-endemic areas of Argentina.

HTLV-1 proviral load (pVL) in peripheral blood mononuclear cell (PBMCs) is proposed as a marker of disease progression but its role still remains controversial. The aim of this study was to evaluate the levels of HTLV-1 pVL in symptomatic patients and asymptomatic HTLV-1 carriers. In this cross-sectional study the pVL was measured by Real Time PCR in 102 asymptomatic carriers and 22 symptomatic patients (5ATLL, 15 TSP and 2 uveitis).
