A method is described that allows, for the first time, intraoperative vibration modes assessment of the acoustically stimulated stapes by means of scanning laser Doppler interferometry (LDI). The study was designed to answer the following questions: 1) Is LDI practical for taking measurements during surgery? 2) Are the results comparable to the findings in(More)
A disinhibition syndrome affecting speech (with logorrhoea, delirium, jokes, laughs, inappropriate comments, extraordinary confabulations), was the main manifestation of a right-sided thalamic infarct involving the dorsomedian nucleus, intralaminar nuclei and medial part of the ventral lateral nucleus. Resolution of conflicting tasks was severely impaired,(More)
OBJECTIVES Laser Doppler interferometry (LDI) of the eardrum allows noncontact optical analysis of its vibrations in response to sound. Although LDI has been widely used in research, it has not yet been introduced into clinical practice as an adjunctive test for otological workup. The aim of this study was to evaluate LDI as a diagnostic tool in the(More)
Our objective was to compare maternal pelvimetry and patient acceptability between open low-field (0.5-T) and closed 1.5-T MR systems. Thirty women referred for pelvimetry (pregnant: n=15) were scanned twice in the supine position, once in the vertical open system and once in the closed system. Each patient completed a comfort and acceptability(More)
The question as to whether the incudo-malleolar joint (IMJ) is mobile or immobile at moderate sound pressure levels (SPLs) is addressed. Referring to the mechanical properties of elastic tissue, we suggest that the IMJ is mobile at any SPL. In order to test this hypothesis, we investigated the dynamics of the IMJ in nine temporal bones by means of laser(More)
INTRODUCTION In a prospective trial, the diagnostic value of laser Doppler interferometry (LDI) was analysed in the clinical sphere. METHOD LDI was compared with standard audiometry for preoperative differential diagnosis of a conductive hearing loss. The intraoperative diagnosis was considered the gold standard. RESULTS LDI was applicable in the(More)
We have studied the cause of stroke in 62 patients aged over 75 years who suffered transient ischemic attacks (TIA) and minor stroke, compared to a control group of younger (age 45-74 years) patients with stroke of the same severity. Patients aged over 75 years had a higher incidence of events of undetermined origin, cardiac embolism, or multiple(More)
A 50-year-old man had a primary lymphoma of the central nervous system one year after a tick bite and a radiculoneuritis secondary to Borrelia burgdorferi infection. Determination of antibodies against Borrelia burgdorferi revealed increasing IgM and IgG titers, and the autopsy showed a primary B-cell immunoblastic lymphoma of the brain without evidence of(More)
