    Cutaneous angiosarcoma of the scalp

    BACKGROUND Angiosarcoma is a malignant tumor of vascular endothelial cells that arises in the head and neck. It is a rare, difficult to treat, and lethal tumor. METHODS Clinical data from patients who were diagnosed with angiosarcoma of the scalp between 1975 and 2002 at the University of Michigan were reviewed. Analysis was performed to assess for factors impacting time to recurrence and survival. RESULTS The study was comprised of 29 patients with a median age of 71.0 years. Most patients presented after a delay in diagnosis with either a bruise-like macule (48.3%) or a nonbruise-like nodule (51.7%). Seventy-five percent of patients had pathologic Stage T2 disease, and 76% of patients had high-grade tumors. Virtually all patients underwent surgical excision (96.6%); however, negative surgical margins were achieved in only 21.4% of patients. Multiple lesions on presentation were associated with a shorter time to recurrence ( P = 0.02). The median actuarial survival was 28.4 months. Younger patients and patients with Stage T1 disease had improved survival ( P = 0.024 and P = 0.013, respectively). Radiation therapy was associated significantly with a decreased chance of death (hazard ratio, 0.16; P = 0.006). CONCLUSIONS Although surgery remains the first option for the treatment of patients with angiosarcoma of the scalp, achieving negative margins often is impossible. Patients who are younger and who have less extensive disease fare better. Postoperative radiation therapy should be employed routinely, as it may lead to improved survival.

    RosettaRemodel: A Generalized Framework for Flexible Backbone Protein Design

    Get PDF
    We describe RosettaRemodel, a generalized framework for flexible protein design that provides a versatile and convenient interface to the Rosetta modeling suite. RosettaRemodel employs a unified interface, called a blueprint, which allows detailed control over many aspects of flexible backbone protein design calculations. RosettaRemodel allows the construction and elaboration of customized protocols for a wide range of design problems ranging from loop insertion and deletion, disulfide engineering, domain assembly, loop remodeling, motif grafting, symmetrical units, to de novo structure modeling

    Chondromyxoid Fibroma of Sphenoid Sinus with Unusual Calcifications: Case Report with Literature Review

    Get PDF
    Chondromyxoid fibroma (CMF) is a rare benign primary tumor which usually affects the metaphyses of the long bone of the lower extremities in childhood and young adults. Rarely, CMF occurs in the skull base and parasinuses, which may be difficult to distinguish from chondrosarcoma or chordoma and other tumors in the head. It is composed of chondroid, myxoid, and fibrous tissue growth in a lobular pattern, infrequently with calcifications. We report one case of CMF involving the sphenoid sinus mimicking a chondrosarcoma. The tumor mass showed calcifications on images and histology

    <p>Abstract</p> <p>Background</p> <p>Footwear characteristics have been linked to falls in older adults and children, and the development of many musculoskeletal conditions. Due to the relationship between footwear and pathology, health professionals have a responsibility to consider footwear characteristics in the etiology and treatment of various patient presentations. In order for health professionals and researchers to accurately and efficiently critique an individual's footwear, a valid and reliable footwear assessment tool is required. The aim of this study was to develop a simple, efficient, and reliable footwear assessment tool potentially suitable for use in a range of patient populations.</p> <p>Methods</p> <p>Consideration of previously published tools, other footwear related literature, and clinical considerations of three therapists were used to assist in the development of the tool. The tool was developed to cover fit, general features, general structure, motion control properties, cushioning, and wear patterns. A total of 15 participants (who provided two pairs of shoes each) were recruited, and assessment using the scale was completed on two separate occasions (separated by 1 – 3 weeks) by a physiotherapist and a podiatrist on each participant's dominant foot. Intra-rater and inter-rater reliability were evaluated using intra-class correlation coefficients (ICCs) (model 2, 1) and the 95% limits of agreement (95% LOAs) for continuous items, and percentage agreement and kappa (κ) statistics for categorical items.</p> <p>Results</p> <p>All categorical items demonstrated high percentage agreement statistic for intra-rater (83 – 100%) and inter-rater (83 – 100%) comparisons. With the exception of last shape and objective measures used to categorise the adequacy of length, excellent intra-rater (ICC = 0.91 – 1.00) and inter-rater reliability (ICC = 0.90 – 1.00) was indicated for continuous items in the tool, including the motion control properties scale (0.91 – 0.95).</p> <p>Conclusion</p> <p>A comprehensive footwear assessment tool with good face validity has been developed to assist future research and clinical footwear assessment. Generally good reliability amongst all items indicates that the tool can be used with confidence in research and clinical settings. Further research is now required to determine the clinical validity of each item in various patient populations.</p
