In a cluster randomized trial, we evaluated the effect of a multifaceted intervention (directed at both patient and primary care physician) on the rates of testing and treatment of osteoporosis in postmenopausal women within six months of their wrist fracture. Compared to usual care, women in the intervention practices were three times more likely to(More)
BACKGROUND Parkinson disease (PD) is a degenerative neurological disorder for which no treatment has been shown to slow the progression. OBJECTIVE To determine whether a range of dosages of coenzyme Q10 is safe and well tolerated and could slow the functional decline in PD. DESIGN Multicenter, randomized, parallel-group, placebo-controlled,(More)
BACKGROUND Although estrogen therapy has been associated with improved cognitive functioning, a reduced risk of dementia in women with Parkinson disease (PD), and a decreased risk of Alzheimer disease, estrogen therapy has not affected the risk of PD per se. OBJECTIVE To determine whether postmenopausal women with PD differed from control subjects with(More)
Risk-taking behavior is characterized by pursuit of reward in spite of potential negative consequences. Dopamine neurotransmission along the mesocorticolimbic pathway is a potential modulator of risk behavior. In patients with Parkinson's disease (PD), impulse control disorder (ICD) can result from dopaminergic medication use, particularly dopamine agonists(More)
Dyskinesia is a recognized but uncommon side-effect of treatment with phenytoin. Two additional cases of dyskinesia during treatment with phenytoin are described; both had radiographically documented thalamic infarctions. The reported experience to date with movement disorders induced by phenytoin is reviewed and the clinical features summarized. The(More)
Brain-derived neurotrophic factor (BDNF) regulates synapses, but the distribution of BDNF and its receptor TrkB relative to the location of glutamatergic and gamma-aminobutyric acidergic (GABAergic) synapses is presently unknown. Immunocytochemistry was performed in primary hippocampal neuron cultures to determine whether BDNF and TrkB are preferentially(More)
Age at onset of Huntington's disease (HD) is correlated with the size of the abnormal CAG repeat expansion in the HD gene; however, several studies have indicated that other genetic factors also contribute to the variability in HD age at onset. To identify modifier genes, we recently reported a whole-genome scan in a sample of 629 affected sibling pairs(More)
We have used the suicide transport agent volkensin to produce selective lesions of striatonigral neurons. By in situ hybridization histochemistry unilateral volkensin injections in the substantia nigra decreased the number of D1 receptor mRNA-expressing neurons in the ipsilateral striatum but did not change the number of D2 receptor and A2a adenosine(More)
We describe a patient who survived for more than 7 years after the diagnosis of meningeal carcinomatosis associated with breast cancer. Meningeal carcinomatosis occurs in 1% to 5% of patients with breast cancer. The median survival ranges from 3 to 7 months, but most reports include a small number of patients who survive considerably longer, with up to 11%(More)
To investigate developmental changes in neurosteroid modulation of GABA(A) receptors, whole-cell currents were elicited by applying GABA with allopregnanolone or pregnenolone sulfate (PS) to dentate granule cells (DGCs), acutely isolated from 7-14-day-old and adult rats. GABA evoked larger currents from dentate granule cells acutely isolated from adult rats(More)
