OBJECTIVE Regardless of the paradigm used to implement a brain-computer interface (BCI), all systems suffer from BCI-inefficiency. In the case of patients the inefficiency can be high. Some solutions have been proposed to overcome this problem, however they have not been completely successful yet. METHODS EEG from 10 healthy users was recorded during(More)
Sir, We read with interest the paper by Reitsamer et al (2004) regarding SLN biopsy without axillary node dissection in a group of 200 patients proven sentinel node negative based on histology (frozen and paraffin-embedded sections) and immunhistochem-istry. After a mean follow-up of 36 months (22 – 56 months), no axillary recurrence has been found so far.(More)

Intrathecal treatment with MTX was attempted in patients with diffuse meningeal blastoses. As a rule, symptoms and clinical findings improved rapidly. As objective parameters, the differential cell pictures of the CSF showed dissimilar results during therapy (25 mg MTX weekly i.t.). In leukoses (n = 10) and malignant lymphomas (n = 12), the CSF could be(More)
