The magnetic resonance imaging (MRI) findings in idiopathic adhesive capsulitis (AC) were compared with those of contralateral healthy shoulders and the reliability of measures assessed. Twenty-six consecutive patients (26 AC and 14 healthy shoulders) were prospectively assessed. The main measurements were thickness of the joint capsule and synovial membrane in the axillary recess and rotator interval in T1-weighted spin-echo sequence enhanced with intravenous (IV) gadolinium chelate (Gd-chelate). Reliability was studied by use of the intraclass correlation coefficient (ICC). The mean thickness of the axillary recess on the coronal plane was 9.0+/-2.2 mm in AC shoulders and 0.4+/-0.7 mm in healthy shoulders. The mean thickness of the rotator interval on the sagittal plane was 8.4+/-2.8 in AC shoulders and 0.6+/-0.8 mm in healthy shoulders. Interobserver reliability was good for the axillary recess, with ICC values of 0.84 for the coronal plane, and good for the rotator interval, with ICC values of 0.80 for the sagittal plane. MRI with IV Gd-chelate injection can show, with acceptable reliability, signal and thickness abnormalities of the shoulder joint capsule and synovial membrane in AC.
Coronavirus disease 2019 (COVID-19) is associated with coagulation activation and high incidence of venous thromboembolism (VTE) in severe patients despite routine thromboprophylaxis. Conflicting results exist regarding the epidemiology of VTE for unselected anticoagulated COVID-19 patients hospitalized in general wards. The aim of this study was to evaluate the prevalence of asymptomatic deep venous thrombosis (DVT) in unselected patients with COVID-19 recently hospitalized in general wards. We performed a systematic complete doppler ultrasound (CDU) at a median 4 days after admission in 42 consecutive COVID-19 patients hospitalized in general wards of our university hospital, irrespective of D-Dimer level, and retrospectively collected clinical, biological and outcome data from electronic charts. Thromboprophylaxis was systematically applied following a French national proposal. In our population, the prevalence of asymptomatic DVT was 19% (8/42 patients), with distal thrombosis in 7/8 cases and bilateral DVT in 4/8 cases. Symptomatic pulmonary embolism was detected in 4 (9.5%) patients, associated to DVT in one case. Compared to patients without DVT, patients with DVT were older and experienced poorer outcomes. In conclusion, prevalence of asymptomatic DVT is high in the first days of hospitalization of unselected COVID-19 patients in general wards and may be related to poor prognosis. Individualized assessment of thromboprophylaxis and early systematic screening for DVT is warranted in this context.
