Sex steroid concentrations in urine samples from post-menopausal women have been associated with risk of various chronic diseases. The basic requirement for the assessment of risk in such large-scale epidemiological studies is that subjects be ranked accurately by their average, long-term hormone levels. We examined the reproducibility over time of(More)
The spinal canal is an uncommon site for abscess formation resulting from bloodstream disseminated infection. Prognosis is often unfavorable. Rapid treatment is essential for satisfactory neurological recovery. Abscesses within the spinal canal are thus diagnostic and therapeutic emergencies. The neuro-infectious and inflammatory manifestations and(More)
In order to evaluate the contribution of computerized tomography (CT) to the diagnosis of cerebral thrombophlebitis, a series of 28 cases was reviewed and compared with data from the literature. In an examination carried out 4 to 5 days of its constitution the thrombus may be directly visualized as a spontaneous hyperdensity. This early but very transient(More)
BACKGROUND Percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass surgery (CABG) improve the clinical status of patients with isolated proximal left anterior descending coronary artery stenosis. At 2 years, only additional revascularization was more frequently required after PTCA. METHODS AND RESULTS We monitored 134 patients(More)
The lesions of the cerebral white matter which characterize Pelizaeus-Merzbacher disease are classically observed at pathological examination. An early diagnosis can now be obtained by magnetic resonance imaging (MRI). In an eutrophic first son born at term, stridor, nystagmus-like eye movements and axial hypotonia were noted immediately after birth and(More)
OBJECTIVES We report on 16 cases of dysembryoplastic Neuroepithelial tumor (DNT) treated in the Nancy University Hospital from 1987 to 1997. PATIENTS AND METHODS There were 9 males and 7 females. Mean age at onset of symptoms was 9.5 years (range: 3 months to 29 years) and the mean age at surgery was 16 years. Nine patients experienced partial complex(More)
Cerebral sulci identification process is based on several formal rules: it consists a series of steps allowing the identification of the major sulci. The process may be variable for each of us and we propose to read the images in certain order starting with the frontal lobe and its superior frontal gyrus than precentral and central gyri followed by the(More)
The main illness of the neural pituitary is diabetes insipidus (DI). MRI is essential if DI occurs during childhood, in order to highlight malignant germinoma prognosis of which remains excellent if the diagnosis is made as early as possible. In adults, primary intracranial tumours causing DI include craniopharyngioma, or pineal tumours. Infiltrative(More)
Correlation of myelin-stained or cryotomic sections of human brain with inversion-recovery MR images can display the cerebral commissures as white-matter tracts (in hypersignal on MRI), crossing the mid-line. MRI shows routinely in three orthogonal planes a) the corpus callosum stretched above the supra-tentorial ventricles, it's four portions (rostrum,(More)
