Vagus nerve stimulation (VNS) has gained recognition as a treatment for refractory epilepsies where surgical treatment is not possible. While it appears that this treatment is effective in some patients, the mechanism of action is not clearly understood. The purpose of this study was to clarify findings of other positron emission tomography and(More)
Immune cells infiltrating the microenvironment of melanoma metastases may either limit or promote tumor progression, but the characteristics that distinguish these effects are obscure. In this study, we systematically evaluated the composition and organization of immune cells that infiltrated melanoma metastases in human patients. Three histologic patterns(More)
PURPOSE Human melanoma cells express shared antigens recognized by CD8(+) T lymphocytes, the most common of which are melanocytic differentiation proteins and cancer-testis antigens. However, peptide vaccines for melanoma usually target only one or two MHC class I-associated peptide antigens. Because melanomas commonly evade immune recognition by selective(More)
We recently performed a retrospective clinicopathologic study of five patients with cutaneous involvement of multiple myeloma or extramedullary plasmacytoma. Cutaneous nodules without extension from an underlying bony focus of disease developed in each case. In two cases skin lesions occurred in the more common setting of advanced disease, but in two others(More)
PURPOSE Members of the SPAN-X (sperm protein associated with the nucleus mapped to the X chromosome) family of cancer-testis antigens are promising targets for tumor immunotherapy because they are normally expressed exclusively during spermiogenesis on the adluminal side of the blood-testis barrier, an immune privileged compartment. EXPERIMENTAL DESIGN(More)
Sarcoidosis is a disease of uncertainty in terms of its cause, presentation, and clinical course. The disease has a worldwide distribution and affects all ages, races, and both sex. Sarcoidosis of the skin may have an extremely heterogeneous clinical presentation, so that the definitions of 'great imitator' and 'clinical chameleon' have long been used. The(More)
BACKGROUND Serotonin transporters (SERT) are a major target for antidepressant medication, although there have been limited in vivo studies of SERT availability in patients being treated with antidepressants. It is not known whether SERT availability differs in treatment-responsive and -nonresponsive patients receiving long-term treatment. In this study, we(More)
Lyme boreliosis is caused by the spirochete Borrelia burdorferi, which is transmitted by ticks. A 59 year-old woman developed pyrexia, strong headaches, ataxia, dysarthria and tremor of the limbs after a tick bite. She was unable to work and eat on her own. She was hospitalized three times and diagnosed with cerebellar intention tremor, cerebellar ataxia,(More)
Sarcoidosis of the skin may have an extremely heterogeneous clinical presentation, so that the definitions of 'great imitator' and 'clinical chameleon' have long been used. There is, in fact, a large group of skin diseases that can enter the differential diagnosis with cutaneous sarcoid manifestations, either clinically or/and pathologically. As the(More)
