    The growing interest in shoulder joint imaging comes from the ever-increasing demand for such an examination in orthopedics. Since more complete and detailed imaging of bone, capsuloligamentous and musculotendinous compartments is always needed, CT arthrography has necessarily become a widely used method. In this study, 282 patients were investigated with CT arthrography. Seventy per cent of them had anatomical instability, 17.3\% had functional instability and the extant 12.7\% had shoulder pain. In traumatic instability, the most often injured structures were the glenoid labra (91\%) and the capsule (82\%). Lesions in the two structures were nearly always associated. Moreover, high incidence (65.8\%) of Hill-Sachs lesions of the humeral head was observed. In atraumatic instability, abnormal anteversion of the scapular glenoid was always detected. In the patients with shoulder pain, the most common causes were the impingement syndrome (30.5\%), superior labrum lesions (16.7\%), adhesive capsulitis (16.7\%) and synovial osteochondromatosis (13.7\%). With CT arthrography, labial abnormalities (detachments, tears, amputations, eversions and degeneration) can be identified, as well as capsular lesions (insertional detachment and laxity), rotator cuff conditions (bursitis, tendinitis and partial/complete tears), biceps tendon abnormalities and glenoid rim and humeral head fractures. Moreover, CT arthrography is minimally invasive and well tolerated. It exhibits 97.7\% specificity, 91\% sensitivity and 96\% accuracy. Furthermore, it has been proven to be extremely useful in treatment and surgical planning

    Objective: This study aims to evaluate the endoprosthesis complications in patients undergoing TEVAR for blunt traumatic thoracic aortic injury, through long-term clinical and diagnostic follow-up. Methods: During the study interval (November 2000-October 2020), a total of 38 patients (63% male; average age 37.5 years) with thoracic aortic injury underwent thoracic endovascular aortic repair. Patients underwent routine follow-up with clinical examination and radiological evaluation (CT-angiography or MRI-angiography plus chest radiograph), scheduled at 1 month, at 6 months (only in the cases of thoracic aortic dissection), at 1 year after the procedure and every 1 year thereafter. Results: Technical success was achieved in 38 procedures (100%). The TEVAR-related mortality rate was 0%. No immediate major complications related to the endovascular procedure were observed. The median duration of diagnostic follow-up was 80 months. A total of four procedure-related complications (10.5%) were identified at the follow-up. Three (7.9%) distal infoldings and collapses of the thoracic endoprosthesis and one (2.6%) type Ia endoleak were observed. No thrombosis of the prosthesis, nor signs of aortic pseudocoarctation were identified. No further complications related to endograft (endoleaks, infections, rupture, partial or complete thrombosis) occurred. No changes in the native aorta, stenosis, or increases in the endograft's diameters were observed. A total of 20 patients (52.6%) underwent MRI-angiography examinations, while a total of 34 patients (89.5%) underwent chest radiographs at the follow-up. In all cases, CT-angiography examinations were performed at the follow-up. Conclusions: Procedure-related complications were observed within one year of TEVAR, limiting concerns related to the durability of the prosthesis. No morphological changes in the aorta were observed despite long-term follow-up. The consequences of lifelong surveillance in terms of radiation exposure deserve special consideration, especially in younger patients treated for TAI

    Relapsing bloodstream infections during treatment of acute leukemia

    Acute leukemia (AL) patients may experience more than one episode of bloodstream infection (BSI) caused by the same pathogen during the entire chemotherapy program. In order to identify factors influencing BSI recurrence (R-BSI) during subsequent phases of treatment, we analyzed all BSIs occurring to consecutively treated AL patients during a period of active epidemiologic surveillance at our institution between 2004 and 2011. Two hundred and fifty BSIs were observed in 138 patients receiving more than 1 cycle of chemotherapy. BSI due to the same pathogen recurred in 39/138 (28.3 %) patients. Gram-negative rods (GNRs) accounted for 59.6 % and Gram-positive cocci (GPCs) for 34.4 % of BSI. Four pathogens were involved in R-BSI: Escherichia coli, Pseudomonas aeruginosa, coagulase-negative staphylococci, and Streptococcus viridans. GNRs were significantly more frequent among R-BSI compared to non-relapsing BSI (nR-BSI) [69/94 (73.4 %) vs 70/156 (50.6 %), p < 0.0001]; in particular, E. coli accounted for 67 % of R-BSI vs 32.1 % of nR-BSI (p < 0.0001). Receiving more than four chemotherapy courses and having an extended spectrum β-lactamase (ESBL)-producing E. coli BSI at any time of treatment were significantly associated to R-BSI. A trend toward a higher mortality among R-BSI patients in comparison with nR-BSI was observed (17.9 and 7.1 %, respectively, p = 0.12). Among AL patients, R-BSI is a frequent phenomenon, which may contribute to the shift of epidemiology toward GNR and to a higher mortality. This should significantly impact the strategies of antibiotic prophylaxis and treatment in patients with AL
