In randomly selected chronic alcoholics hospitalised for the first time for detoxification a high prevalence (68%) of cognitive deficits was found. Peripheral neuronal damage was seen in 74%, autonomic neuronal damage in 24%. Cognitive deficits were not correlated with age, daily ethanol intake, duration of alcohol abuse or severity of liver damage. There(More)
A deficit of nigrostriatal, mesocortical and mesolimbic dopamine systems in Parkinson's disease is well known. We know less about the involvement of tuberoinfundibular dopamine (TID) systems. In untreated (naive or wash-out) men with Parkinson's disease, we studied TID function through basal and stimulated plasma levels of growth hormone, prolactin and(More)
Experimental and human data in young volunteers suggest that tuberoinfundibular dopaminergic systems physiologically inhibit pituitary secretion of beta-endorphin. This hypothesis was verified in patients with Parkinson's disease, a human model of a selective deficit of dopamine. Both previously untreated patients and patients who had been without chronic(More)
of 3.5-5 months. Historically, radiotherapy alone has been the standard treatment for PCNSL; however, radiotherapy is rarely a curative treatment in PCNSL patients since response is usually short-lived, with a median survival of 12-14 months. 12,13 Moreover, the positive impact of chemotherapy progressively limited the indications for radiotherapy alone.(More)
The "glucocorticoid cascade hypothesis" for pathological ageing of the brain is supported by strong experimental data, but the clinical correlates are far less clear. The basal ACTH and cortisol secretion have been studied before and after the dexamethasone suppression test in patients in the early stages of clinically probable Alzheimer's disease and in(More)
Cerebral venous thrombosis (CVT) may represent the clinical onset of malignancies or complicate their course, also in phase of quiescence. In literature, there are several case reports on the association between CVT and tumors, but there are few articles on its clinical characteristics in cancer patients (Pts). Our aim was to analyze the clinical(More)
Laminin may alter the biological behavior of gliomas. Therefore, we investigated the expression of two laminin receptors, alpha6 beta1 and alpha6 beta4 integrins in normal brain, astrogliotic brain, and astrocytomas as compared to other central nervous system (CNS) tumors. In most CNS tumors, the expression of these integrins was unchanged in neoplastic as(More)
Thirty four patients who had complete ischemic stroke confirmed by neurologic examination, were divided into three groups according to the time elapsed between the first signs of stroke and lumbar puncture: group A, 22-47 h; group B, 48-71 h; group C, 72-96 h. Nineteen patients with multi-infarct dementia (MID) assessed by neurologic and neurophysiologic(More)
