Blood tests to detect circulating tumor cells (CTC) offer great potential to monitor disease status, gauge prognosis, and guide treatment decisions for patients with cancer. For patients with brain tumors, such as aggressive glioblastoma multiforme, CTC assays are needed that do not rely on expression of cancer cell surface biomarkers like epithelial cell(More)
Immunoblotting sera from 26 patients with septicemia due to an epidemic strain of methicillin-resistant Staphylococcus aureus (EMRSA-15), 6 of whom died, revealed an immunodominant EMRSA-15 antigen at 61 kDa. There was a statistically significant correlate (P < 0.001) between survival and immunoglobulin G to the 61-kDa band. The antigen was identified by(More)
We describe a new X-linked syndrome of marked short stature, severe intellectual handicap and an unusual facial appearance. High resolution prometaphase banding showed affected males to have an X chromosome tandem duplication; their karyotypes were designated 46,dup(X) (q13.1-q21.1)Y. In carrier females the abnormal X chromosome was late replicating. To(More)
We report on a family with an abnormality of 10p. The propositus has monosomy for the distal region of 10p and severe psychomotor delay, growth failure, congenital heart defect, multicystic kidney, grade V vesicoureteric reflux, and neurosensory hearing loss. The mother and the elder brother of the propositus carry a balanced reciprocal translocation(More)
A range of estimates for sickle cell and beta thalassaemia have been derived for the different ethnic groups living in the U.K., reflecting uncertainty over the true population value in certain countries and the heterogeneity within and between countries of origin comprising the same ethnic group. These were validated against six community screening(More)
Spondyloepiphyseal dysplasia tarda (SEDT) is an X-linked recessive disorder characterized by short stature due to defective growth of the vertebral bodies. In addition, deformities of the femoral heads result in early onset secondary osteoarthritis of the hips. The disorder affects males only with heterozygous female carriers showing no consistent(More)
BACKGROUND With the identification of genes predisposing to hereditary breast cancer, the accurate and consistent estimation of a woman's risk of developing breast cancer based on her family history is of paramount importance if national service guidelines are to be developed. PATIENTS AND METHODS The residual lifetime risk of developing breast cancer was(More)
Glioblastoma multiforme (GBM) is a common, usually lethal disease with a median survival of only ~15 months. It has proven resistant in clinical trials to chemotherapeutic agents such as paclitaxel that are highly effective in vitro, presumably because of impaired drug delivery across the tumor's blood-brain barrier (BBB). In an effort to increase(More)
The field of radiation oncology has evolved, especially in the past 20 years. Advances in technology, particularly in computing power, software, and imaging, have fueled contributions to cancer care. It is currently fashionable to say that many of these advances have only served to increase costs of care without clear evidence of benefit, and certainly,(More)
Melnick-Needles syndrome (MNS) is a female-limited skeletal dysplasia inherited in a X-linked dominant pattern. Males born to women with MNS may exhibit lethal multiple congenital anomalies, but recurrence of this phenotype within one family has not been reported. Males with oto-palato-digital syndrome type II (OPD II) also demonstrate a multiple congenital(More)
