Angiosarcoma is a rare complication of breast cancer treatment. In order to define predictors, clinical presentation, and
outcome, we characterized a population-based 50-year cohort of angiosarcomas after breast cancer. Clinical data were collected
from all females with previous breast cancer who developed angiosarcomas/lymphangiosarcomas on the thoracic wall/upper extremity
between 1958 and 2008 in the Southern Swedish health care region. In total, 31 angiosarcomas developed at a median age of
71 years. The patients formed two distinct groups; 14 females treated for breast cancer with radical mastectomy and radiotherapy
1949–1988 developed angiosarcomas in edematous arms (Stewart–Treves syndrome) after median 11 years, and 17 females treated
by segmental resection, anti-hormonal treatment and radiotherapy 1980–2005 developed angiosarcomas in the irradiated field
on the thoracic wall after median 7.3 years. The clinical presentations were heterogeneous and included hematoma-like lesions,
multiple bluish-reddish nodules, and asymptomatic lumps. The overall 5-year survival was 16%. In this population-based cohort,
the early angiosarcomas developed in edematous arms after radical mastectomies, whereas more recent cases occurred after a
shorter time period in the irradiated fields following breast conserving surgery. We conclude that the clinical presentation
of angiosarcomas has changed, parallel with altered treatment principles for breast cancer. 相似文献

Background and purpose An acetabular labral tear is a diagnostic challenge. Various clinical tests have been described, but little is known about their diagnostic sensitivity and specificity. We investigated the diagnostic validity of clinical tests and ultra-sound as compared with MR arthrography.Patients and methods We examined 18 patients (18 hips, 2 men, median age 43 (32–56) years) with impingement test, FABER test, resisted straight leg raise test, ultrasound, and MR arthrography. They had had previous periacetabular osteotomies due to symptomatic, acetabular dysplasia. All hips showed no or only slight signs of osteoarthritis (Tönnis grade 0–1).Results MR arthrography identified labral tears in 17 of the 18 hips. Ultrasound had a sensitivity of 94%, a positive predictive value of 94%, and was false negative in only 1 case compared to MR arthrography. The impingement test had the best diagnostic ability of the clinical tests, with a sensitivity of 59% and a specificity of 100%. The positive predictive value was 100% while the negative predictive value was 13%.Interpretation The impingement test is helpful in identifying acetabular labral tears. If this test is negative and if a labral tear is still suspected, ultrasound can reliably diagnose most tears of the acetabular labrum. MR arthrography is indicated in cases where ultrasound is negative, but the patient suffers continued, specific symptoms. 相似文献

Core decompression by exact drilling into ischemic lesions of the femoral condyle stays a challenging procedure, particularly in obese patients. The precision of fluoroscopically-based drilling compared to conventional drilling was evaluated in an in-vitro model for obesity. 40 sawbones were prepared mimicking osteonecrosis in obese patients. 20 sawbones were drilled by guidance of an intraoperative navigation system VectorVision® (BrainLAB, Munich, Germany); the other 20 sawbones were conventionally drilled by fluoroscopic control only. Regarding the distance to the desired mid-point of the lesion, a statistically significant difference with 0.55 mm in the navigated group and 1.19 mm in the control group could be stated (p<0.001). Significant differences were further found for the number of drilling corrections (p<0.001) and radiation time needed (p<0.001). Even in difficult circumstances as in obese patients, the drilling guided by the VectorVision®-navigation system shows high precision with simultaneous enormous reduction of radiation time. 相似文献

A method is presented for empirical subclassification of autistic and autisticlike children, based on observations of current behavior. The advantage of the method is that it identifies profiles of cooccurring behaviors and accordingly assigns children to subtypes. The subtypes are more clinically homogeneous than the overall sample of autistic children. Preliminary findings are presented, including an effort to validate the subclasses by suggesting possible relationships between subtype membership and perinatal markers, developmental milestones, and independent measures of concurrent behavior.This work was supported by postdoctoral training grants MH-15147 and MH-16744 from the National Institute of Mental Health (Siegel), by the Scottish Rite Foundation (Anders, Siegel), by the John Merck Fund (Ciaranello), and by the National Institute of Mental Health grant MH-38064 (Anders, Ciaranello). A portion of this work was presented at the Annual Meeting of the National Society for Children and Adults with Autism, Salt Lake City, July 1983. 相似文献

Chicken antibodies have several advantages over mammalian antibodies due to the phylogenetical differences between birds and mammals, resulting in an increased sensitivity and a decreased background in many immunological assays. So far, there has been a very limited use of avian antibodies. This is probably partly due to tradition but also because there are very few optimized methods for the labelling of chicken antibodies. We report upon the suitable conditions for peroxidase-labelling of chicken antibodies with a modified periodate method. 相似文献
