BACKGROUND Central nervous system (CNS) disease as the site of first relapse after exposure to adjuvant trastuzumab has been reported. We carried out comprehensive meta-analysis to determine the risk of CNS metastases as the first site of recurrence in patients with HER2-positive breast cancer who received adjuvant trastuzumab. METHODS Eligible studies include randomized trials of adjuvant tr...

Plasmacytoid dendritic cells (pDCs) have both stimulatory and regulatory effects on T cells. pDCs are a major CNS-infiltrating dendritic cell population during experimental autoimmune encephalomyelitis but, unlike myeloid dendritic cells, have a minor role in T cell activation and epitope spreading. We show that depletion of pDCs during either the acute or relapse phases of experimental autoimm...

An effective therapy for multifocal central nervous system hemangioblastoma (CNS HB) is needed. Here, we report a case of multifocal CNS HB. A 43-year-old man was diagnosed with CNS HB by enhanced computed tomography and magnetic resonance imaging. Six solid tumors and one cystic nodule were detected in his cerebellum. The patient underwent three surgeries followed by knife radiosurgery and had...

Central nervous system (CNS) involvement by chronic lymphocytic leukemia (CLL) can present with dramatic neurologic findings or can be quite subtle, discovered only at the time of autopsy. We describe a case of CLL in a patient who presented initially with hearing loss and was ultimately found to have involvement of the tympanic membrane. She noted improvement of her hearing after induction the...

Stress plays a key role in addiction etiology and relapse. Rodent models posit that following repeated periods of alcohol and other drug intoxication, compensatory allostatic changes occur in the central nervous system (CNS) circuits involved in behavioral and emotional response to stressors. We examine a predicted manifestation of this neuroadaptation in recently abstinent alcohol-dependent hu...

Metalloproteinases have been implicated in the pathogenesis of multiple sclerosis. We report longitudinal serum levels of gelatinase B and of the tissue inhibitors of matrix metalloproteinases (TIMP), TIMP-1 and TIMP-2, in 21 patients with relapsing multiple sclerosis. Patients had monthly clinical and gadolinium-enhanced MRI follow-up for 10 months. Longitudinal samples in nine healthy control...

To evaluate the outcome of children with high hyperdiploid acute lymphoblastic leukemia (hHDALL) treated at the author's institution. One hundred thirty-five consecutive children with B-precursor ALL were diagnosed between 1991 and 2002: 38 (28.1%) hHDALL and 97 (71.9%) non-hHDALL. In the hHDALL group, 11/38 (28.9%) relapsed at a median interval of 2.8 years (range: 0.8-5.0 years) with 9/11 rel...
