In the present study, the authors show that 1, 25 (OH)2 D3 given to hemodialyzed patients taking Al (OH)3, increased their plasma concentrations of Al. Two mechanism can explain this increase: increased intestinal absorption or decreased tissue storage of Al.
We present an atypical case of neurofibromatosis marked by young age at onset, rapid invasiveness of the tumor, the presence of curious autonomic symptoms, cranial malformation and congenital microphthalmus, a combination that suggests a new syndrome, which might be called childhood microphthalmic neurofibromatosis.
An asymmetric distribution of GABA binding sites was found in the cerebral cortex, hippocampus, cerebellar hemispheres, striatum, and thalamus. Higher levels of [3H]GABA binding were observed in the left-side of most brain areas and in a greater percentage of adult rats, but the opposite asymmetry was found in the thalamus. A similar left-right difference in cerebral hemispheres was also found in five day-old rats, suggesting the genetic predetermination of asymmetry.
A clinical and electrophysiological study was carried out on 19 selected patients with chronic liver disease. Clinical signs of peripheral nerve involvement were found in 4 patients (21%); while electrophysiological impairment was present in 11 patients (57.8%). These abnormalities were mostly limited to the sensory and motor fibers of the tibialis posterior nerve. Our data confirm the presence of peripheral nerve involvement in chronic liver disease, and that it may be evidenced by careful electrophysiological examination.

OBJECTIVE: To investigate the association between cigarette smoking, alcohol drinking, coffee consumption and Parkinson's disease (PD). METHODS: We selected subjects affected by idiopathic PD, with a Mini-Mental State Examination of > or =24, and controls matched 1 to 1 with cases by age (+/- 2 years) and sex. Controls were randomly selected from the resident list of the same municipality of residence of the cases. We assessed cigarette smoking, alcohol drinking, and coffee consumption preceding the onset of PD or the corresponding time for controls using a structured questionnaire, which also evaluated the duration and dose of exposure. Using conditional logistic regression analysis, we calculated adjusted OR and 95% CI. RESULTS: We interviewed 150 PD patients and 150 matched controls. Cigarette smoking (ever vs. never smokers OR = 0.66, 95% CI = 0.41-1.05, p = 0.08) did not show a statistically significant association with PD. We observed an inverse association between alcohol drinking (ever vs. never OR = 0.61, 95% CI = 0.39-0.97, p = 0.037) and coffee consumption (ever vs. never OR = 0.16, 95% CI 0.05-0.46, p = 0.0001) and PD. These associations remained significant after adjustment for other covariates: OR for ever vs. never alcohol consumption was 0.62 (95% CI = 0.43-0.89, p = 0.009) and that for coffee drinking 0.19 (95% CI = 0.07-0.52, p = 0.001). Heavy coffee consumption confirmed the inverse association between coffee and PD (more than 81 cup/year vs. none: OR = 0.20, 95% CI = 0.08-0.47, p < or = 0.0001). CONCLUSIONS: Consistent with previous studies, our results suggest an inverse association between coffee drinking, alcohol consumption and PD. The multiple inverse association observed may indicate a complex interaction between genetic and environmental factors.

The lack of certain etiopathogenetic elements and the numerous clinical-descriptive classifications of primary headaches has brought the research-workers to elaborate a chrono-pathological classification of pain in the primary headaches. So, they present a chrono-nosography and they suggest that the continuous form of primary headaches can be divided into two forms, one of these is associated with affective troubles. Then they emphasize the problem of classic migraine and its clinical variant as a trigger of vascular disease.
