Among patients who successfully completed 1 yr of intense dietary intervention, nine of 15 patients with NASH displayed histologic improvement. This pilot study suggests that dietary intervention can be effective in improving histology in patients with biopsy-proven NASH.

Recurrent rotator cuff tears are not uncommon after arthroscopic repair of large and massive tears. These recurrent tears appear to occur more frequently in the early postoperative period (within the first 3 months) and are associated with inferior clinical outcomes.

Peripheral nerve sheath tumors are often hypoechoic with posterior acoustic enhancement and so may simulate a ganglion cyst. The presence of intrinsic blood flow on color Doppler sonography and peripheral nerve continuity suggests the diagnosis of peripheral nerve sheath tumor. Sonography cannot reliably distinguish neurofibromas from schwannomas.

Purpose: Aggressive fibromatoses (AF; desmoid tumors) are rare clonal neoplastic proliferations of connective tissues that can be locally aggressive despite wide surgical resection and/or radiation therapy. The Sarcoma Alliance for Research through Collaboration (SARC) initiated a prospective phase II trial to investigate the outcome of patients treated with imatinib, a multiple tyrosine kinase inhibitor, in patients with AF, or 1 of 10 sarcoma subtypes. Here, we report specifically on the outcome of patients with AF as well as evaluations undertaken to examine the mechanism of imatinib.Experimental Design: Patients ≥10 years old with desmoid tumors that were not curable by surgical management or in whom curative surgery would lead to undesirable functional impairment were eligible. Imatinib was prescribed at 300 mg twice daily [body surface area (BSA) ≥ 1. ), or 100 mg twice daily (BSA < 1.0 m 2 ). Response outcomes at 2 and 4 months were assessed. Tissue specimens were analyzed by immunohistochemistry for expression of cKIT, plateletderived growth factor receptor α (PDGFRα), PDGFRβ, AKT, PTEN, FKHR, and β-catenin. Tumor DNA was analyzed for PDGFRα exon 18 and APC mutations by allelic discrimination PCR. Results: Fifty-one patients were enrolled. The median number of prior regimens was 1. Kaplan-Meier estimates of 2-and 4-month progression-free survival rates were 94% and 88%, respectively, and 1-year progression-free survival was 66%. Objective response rate was 6%

Altered mobility patterns in asymptomatic professional baseball pitchers may be due to factors other than capsular adaptive changes.

US can be used effectively to locate wooden foreign bodies as small as 2.5 mm in length. Given that many foreign bodies are radiographically undetectable, the accuracy and availability of US make it an excellent modality for evaluation of radiolucent foreign bodies.
