BACKGROUND Clinicians may receive requests to deactivate pacemakers and implantable cardioverter-defibrillators (ICDs) in terminally ill patients. METHODS We describe practices and attitudes regarding deactivation of pacemakers and ICDs in terminally ill patients among physicians, nurses, and others who manage treatment of patients with implanted cardiac(More)
The clinical significance of anaplastic features, a rare event in pilocytic astrocytoma (PA), is not fully established. We reviewed 34 PA with anaplastic features (Male = 21, Female = 13; median age 35 y, 5 to 75) among approximately 2200 PA cases (1.7%). Tumors were included which demonstrated brisk mitotic activity [at least 4 mitoses/10 high power fields(More)
BACKGROUND Bisphenol A (BPA) is widely used in the manufacture of polycarbonate plastics, including infant formula bottles. OBJECTIVES Based on the reported endocrine disruptor activity of this polyphenol, we hypothesized that exposure to BPA early in life would elicit developmental changes in the mammary tissue and cause a predisposition for mammary(More)
OBJECTIVE To describe management of patients with permanent pacemaker (PPM)- and implantable cardioverter-defibrillator (ICD)-related endocarditis. PATIENTS AND METHODS We retrospectively reviewed all cases of infection involving PPMs and ICDs among patients presenting to Mayo Clinic's site in Rochester, MN, between January 1, 1991, and December 31, 2003.(More)
Through our diet, we are exposed to numerous natural and man-made chemicals, including polyphenols with hormone-like properties. The most abundant hormonally active polyphenols are characterized as weak estrogens. These chemicals are hypothesized to interfere with signaling pathways involved in important diseases such as breast cancer, which in most cases(More)
The authors have reassessed the anatomic distribution of ectopic endometrium by the laparoscopic study of the location of implants, adhesions, and uterine position in 182 consecutive patients with infertility and endometriosis. The ovary was the most common site of implants with 54.9% having either unilateral or bilateral involvement. This was followed, in(More)
Pilocytic astrocytomas (PA) are well-differentiated gliomas having a favorable prognosis when compared with other diffuse or infiltrative astrocytomas. Molecular genetic abnormalities and activation of signaling pathways associated with clinically aggressive PA and histologically anaplastic PA have not been adequately studied. We performed molecular(More)
OBJECTIVES Opsoclonus-myoclonus-ataxia (OMA) syndrome affects 2% to 3% of patients with neuroblastoma. This study examined relationships between long-term neurobehavioral outcomes and potential biologic markers of OMA, including chronic changes on magnetic resonance imaging (MRI) brain scanning and prevalence of late antineuronal antibodies. STUDY DESIGN(More)
A 51-year-old gentleman with no significant past medical history presented with a WFNS grade 1 subarachnoid haemorrhage. Initial angiographic investigations revealed no cause, but repeat tests showed a small basilar perforator aneurysm. Following a failed attempt at endovascular treatment, a craniotomy and excision of the aneurysm was performed.(More)
The Turin Proposal algorithm defines poorly differentiated carcinoma on the basis of the presence of solid/trabecular/insular growth pattern, absence of conventional nuclear features of papillary carcinoma, and the presence of at least one of the following features: convoluted nuclei, mitotic activity > or =3/10 HPF, or tumor necrosis. IMP3 appears to have(More)
