Abstract
PURPOSE To perform a Delphi consensus for the treatment of patients with shoulder impingement with intact rotator cuff tendons, comparing North American with European shoulder surgeon preferences. METHODS Nineteen surgeons from North America (North American panel [NAP]) and 18 surgeons from Europe (European panel [EP]) agreed to participate and answered 10 open-ended questions in rounds 1 and 2. The results of the first 2 rounds were used to develop a Likert-style questionnaire for round 3. If agreement at round 3 was ≤60% for an item, the results were carried forward into round 4. For round 4, the panel members outside consensus (>60%, <80%) were contacted and asked to review their response. The level of agreement and consensus was defined as 80%. RESULTS There was agreement on the following items: impingement is a clinical diagnosis; a combination of clinical tests should be used; other pain generators must be excluded; radiographs must be part of the workup; magnetic resonance imaging is helpful; the first line of treatment should always be physiotherapy; a corticosteroid injection is helpful in reducing symptoms; indication for surgery is failure of nonoperative treatment for a minimum of 6 months. The NAP was likely to routinely prescribe nonsteroidal anti-inflammatory drugs (NAP 89%; EP 35%) and consider steroids for impingement (NAP 89%; EP 65%). CONCLUSIONS Consensus was achieved for 16 of the 71 Likert items: impingement is a clinical diagnosis and a combination of clinical tests should be used. The first line of treatment should always be physiotherapy, and a corticosteroid injection can be helpful in reducing symptoms. The indication for surgery is failure of no-operative treatment for a minimum of 6 months. The panel also agreed that subacromial decompression is a good choice for shoulder impingement if there is evidence of mechanical impingement with pain not responding to nonsurgical measures. LEVEL OF EVIDENCE Level V, expert opinion.

Abstract
Mesenteric vein thrombosis (MVT) is a rare cause of intestinal ischemia. Because of its nonspecific symptoms, diagnosis is often delayed. We describe a patient with liver cirrhosis who developed acute MVT while waiting for liver transplantation. Surgical intervention carried a high risk because of her underlying cirrhosis. Mesenteric venous thrombectomy and thrombolysis were performed with an AngioJet (Possis Medical, Minneapolis, MN) thrombectomy device and streptokinase infusion through transjugular route. The patient subsequently received an orthotopic liver transplant. We also present a review of the literature about the occurrence and treatment options for MVT.

Abstract
To determine if chest radiographic findings differ in adult tuberculosis patients with recent and remote infection, we reviewed the chest radiographs of 103 patients with tuberculosis in Los Angeles and performed RFLP analyses of their Mycobacterium tuberculosis isolates. Patients whose isolates had identical or closely related RFLP patterns were considered a "cluster." Most patients in large clusters (more than seven patients) had tuberculosis from recent infection, whereas most unclustered patients had tuberculosis from remote infection. Mediastinal adenopathy or pleural effusions were classified as typical of recent infection, and upper lobe infiltrates, cavitation, or fibrosis were classified as characteristic of remote infection. Radiographic patterns were typical of remote infection in 62% of patients and were characteristic of recent infection in 23% of patients. The distribution of these radiographic patterns was similar in clustered and unclustered patients, both with or without human immunodeficiency virus (HIV) coinfection. However, mediastinal adenopathy and pleural effusions were significantly more common in HIV-infected patients. We conclude that: (1) chest radiographic findings in adults with tuberculosis of recent infection are similar to those in patients with remote infection; (2) the distinctive chest radiographic findings in HIV-infected patients with tuberculosis are not due to an increased frequency of recent infection.

Abstract
Magnetic resonance imaging (MRI) is a recently developed diagnostic medical imaging technology that shows great promise in the evaluation of knee meniscal diseases. Fifty-seven patient knees were evaluated by a single experienced MRI interpreter; the findings were compared with arthroscopic findings by a single experienced knee arthroscopist. The overall sensitivity and specificity rates of MRI for tears in virgin menisci compared to arthroscopy were both 92%. These results support reports in the literature that MRI is an accurate noninvasive technique for evaluating meniscal tears. Seven patients were treated with arthroscopic meniscal repair and were evaluated by MRI before and after surgery. Despite an asymptomatic postoperative status in six patients, abnormal intrameniscal signal persisted in four. An unstable meniscal fragment was visualized in the patient with postoperative pain. MRI is also useful in evaluating meniscal degeneration, meniscal ossicles, parameniscal cysts, and abnormal meniscal morphology. MRI is the noninvasive diagnostic technique of choice in evaluating a spectrum of knee meniscal diseases.

Abstract
Focal abnormal signal intensity within the distal femoral condyles or proximal tibial plateaus is frequently seen on T1- or intermediate-weighted magnetic resonance (MR) images of the knee. To characterize the prevalence and significance of these findings better, a retrospective study of MR imaging of the knee, performed on the first 434 consecutive patients at a primarily outpatient community MR imaging center, was undertaken. A signal intensity loss demonstrated on images with a short echo time (20 or 25 msec) was divided into three types based on morphologic criteria. A type 1 finding was a diffuse, often reticulated signal intensity loss in the metaphyseal and epiphyseal regions of bone. A type 2 loss was associated with an interruption in the smooth, black cortical line. A type 3 finding was a profound signal intensity loss primarily restricted to the immediate subcortical region. Seventeen percent of all cases revealed a type 1 or 2 loss that may have been compatible with acute bone injuries. These bone lesions were frequently associated with tears of the anterior cruciate ligament and contralateral collateral ligament, but infrequently these lesions were detected with plain radiography and arthroscopy. When associated with a weight-bearing cortex, bone injuries detected with MR imaging may explain clinical symptoms of pain on weight bearing, and type 1 injuries may represent regions of bone at increased risk for the subsequent development of insufficiency fractures if the bone is not adequately protected during trabecular healing.
