Hemifacial spasm (HFS) is a movement disorder characterised by involuntary paroxysmal facial movements that usually involve the orbicularis oculi and then spread to the other facial muscles. A microvascular compression and demyelination of the seventh nerve at its exit from the brain stem is considered to be the main aetiology of HFS. In addition to rare(More)
We sought to determine the effect-site concentration of remifentanil blunting sympathetic responses to tracheal intubation and skin incision during bispectral index (BIS)-guided propofol anesthesia. Forty-one ASA physical status I-II patients, aged 20-65 yr and undergoing major abdominal surgery, were randomly assigned to one of two groups: tracheal(More)
It has previously been demonstrated that both Myelin Basic Protein (MBP) and S-100 are released in the cerebrospinal fluid (CSF) of multiple sclerosis (MS) patients during acute phases of exacebation of the disease. In order to investigate the pathobiological significance of the release of these two proteins into the CSF, MBP and S-100 were assayed in 10 MS(More)
Several investigators have described the altered sleep patterns in Down's syndrome subjects. The most relevant findings have been a reduction in percentage of REM sleep, a prolonged latency to the first REM episode, an increase in undifferentiated sleep, and a reduced ratio of the oculomotor frequencies. Because it is of interest to identify new drugs able(More)
BACKGROUND The aim of this prospective, randomized, double-blind study was to determine the effects of two different target-controlled concentrations of remifentanil (1 and 3 ng/ml) on the sevoflurane requirement for blunting sympathetic responses after surgical incision (MACBAR). METHODS Seventy-four patients aged 20-50 yr, with American Society of(More)
Brainstem auditory evoked potentials were recorded in 4 subjects and pattern reversal evoked potentials in 1 subject, all with tuberous sclerosis. Alterations were found (absence or delay of components and prolonged interpeak intervals) which may suggest impaired nervous conduction also at brainstem level in patients with tuberous sclerosis.

Butoctamide hydrogen succinate (BAHS) has been proved to increase REM sleep in patients with reduced REM sleep. Following previous experiments on the effects of BAHS on nocturnal sleep of mentally retarded (MR) subjects, a polygraphic study was conducted on 20 MR subjects (age 8–14 years) to verify the effects of BAHS, 1) after long-term administration and(More)
