Impact of obesity on survival in COVID-19 ARDS patients receiving ECMO: results from an ambispective observational cohort.

Background: Since March 2020, health care systems were importantly affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak, with some patients presenting severe acute respiratory distress syndrome (ARDS), requiring extra-corporeal membrane oxygenation (ECMO). We designed an ambispective observational cohort study including all consecutive adult patients admitted to 5 different ICUs from a university hospital. The main objective was to identify the risk factors of severe COVID-19 ARDS patients supported by ECMO associated with 90-day survival.

Is the trapezius transfer a useful treatment option for irreparable tears of the subscapularis?

Introduction: When suture of the torn subscapularis could not be performed, a superior trapezius transfer was used for repair of the tendinous defect. The aim of this article is to report the mid-term functional and radiographic outcome of this technique when complete watertight rotator cuff healings were achieved and to investigate the usefulness of the trapezius transfer. The hypothesis of this work was that the trapezius transfer could not be considered as a useful treatment option.

Acromio humeral distance less than six millimeter: its meaning in full-thickness rotator cuff tear.

Unlabelled: The present study sought to identify full-thickness rotator cuff tears liable to induce an acromiohumeral distance (AHD) of less than 6 mm. The hypothesis was that, less than 6mm AHD is found exclusively in association with total full-thickness infraspinatus tear.

Materials: A continuous single-center series recruited 109 shoulders, free of glenohumeral osteoarthritis, presenting with full-thickness tear requiring surgery.

[Study of the middle ear. Value of multiplanar reconstructions in spiral tomodensitometry].

We point out the interest of computed tomographic reconstructions from spiral acquisition--particularly sagittal reconstructions--in the study of middle ear anatomy and adjacent structures: the facial canal and the chorda tympani. The reference reconstructions are axial and coronal reconstructions. So, we demonstrate the superiority of sagittal reconstructions for the visualization of the lateral process of the malleus, the body and long process of the incus, the third portion of the facial canal, and the chorda tympani.
