RESUMEN

INTRODUCTION: Point of care ultrasound (POCUS) is routinely used by intensivists and emergency physicians for many years. Its interest is not arguable any more for these specialists, despite the large variety of diseases they care. Hospitalists and internists also should find some interest in POCUS, which convenience and wide range of indications responds well to the variety of their practice. However, it is still not widely used in internal medicine departments. METHODS: We here report our experience of using a pocket-sized ultrasound device in a French internal medicine department. The device used was a Vscan Dual Probe, GE, whose two probes and presets allow for cardiac, abdominal, pulmonary, obstetric, vascular, pulmonary, and superficial soft tissue exploration. One physician of the ward received a course for POCUS that was initially dedicated for emergency physicians. This study reports on the results of the examinations made between January and September 2015. For each examination performed, clinical usefulness was assessed at the time of patient discharge, by two independent physicians who reviewed the clinical course and the results of conventional imaging and rated their evaluation on a Likert scale. RESULTS: One hundred and four examinations were evaluated. The mean duration of the ultrasound examination was 9±5minutes. The POCUS conclusions were corrected by disease course or the results of conventional imaging in 10 (9.6%) cases. The presets of the device: heart, soft tissue, lung, abdomen and vascular were used respectively in 32, 30, 21, 12 and 5% of the examinations. The main indications of POCUS examination were for identification of pleural, pericardial or peritoneal effusion, and to assess the central venous pressure by inferior vena cava examination. Eighteen examinations were performed for puncture of effusion. The retrospectively evaluated clinical benefit was clearly demonstrated in 78% of cases. The agreement between the two blinded assessors was good (kappa coefficient at 0.82). CONCLUSION: Pocket-sized ultrasound device could be used in internal medicine wards. However, its limited performance compared to more sophisticated echography limits the possible explorations and their reliability, which encourages caution and makes critical the question of the initial training of doctors and medical students.

RESUMEN

Autogenous bone graft (autograft) remains the gold standard in the treatment of many orthopedic problems. However, graft harvest can lead to perioperative morbidity and increased cost. We tested the hypothesis that an osteoconductive matrix, beta-tricalcium phosphate (ß-TCP), would be a safe and effective alternative to autograft alone. Beta-tricalcium phosphate (ß-TCP) is considered as one of the most promising biomaterials for bone reconstruction. This study analyzes the outcomes of patients who received ß-TCP as bone substitutes in orthopedic surgery. METHODS: A total of 50 patients were enrolled in a controlled, non-inferiority clinical trial to compare the safety and efficacy of ß-TCP (25 patients) with those of autograft (25 patients) in indications requiring usually autograft. These 50 patients were categorized according to the etiology and morphology of the 54 bone defects resulting from elective surgical procedures, such as 34 open-wedge high tibial osteotomies, and 20 osteonecrosis treatments with core decompression. Radiographic (healing process with or without integration of ß-TCP), clinical (no other surgical procedure), functional outcomes and safety (with or without complications) were assessed through fifty-two weeks postoperatively. RESULTS: With regard to the primary endpoint (radiographic evolution), the fusion rate of the 34 open-wedge osteotomies was 100% (17 among 17) for patients in the group with ß-TCP compared with 94% (16 among 17) for patients in the autograft group. For the 20 cavitary defects (osteonecrosis), the radiographic union rates, as determined by the presence of osseous bridging, were 100% for patients in the group with ß-TCP and 100% for those in the autograft group. Clinically at one year, all quality-of-life and functional outcome data supported non-inferiority of ß-TCP compared with autograft, and patients in the ß-TCP group were found to have less pain and an improved safety profile. CONCLUSIONS: Treatment with ß-TCP resulted in comparable fusion rates, less pain and fewer side effects as compared with treatment with autograft. This study established clinical parameters where the ß-TCP alone can successfully support the osteogenic process.
