Summary The authors discuss about five cases of diabetes insipidus observed in patients affected by traumatic cervical spine fractures and/ or dislocations, without either evident lesions of the cerebral structures at CT scan examination, or important craniocerebral trauma.In all patients polyuria and hyperthermia arose some days after the traumatic accident and regressed spontaneously or after exogeneous vasopressin administration.Vasopressin urinary levels confirmed the presence of a true diabetes insipidus, the origin of which is in largely obscure. A central medullary vasopressin mediated pathway, demonstrated only in experimental animals, may be responsible for such a finding. 相似文献

We describe the case of a patient who, during the percutaneous thermocoagulation of the petrous ganglion of Andersch, suffered a serious vagal response resulting in cardiac arrest, collapse, and generalized convulsions. Notwithstanding such major symptoms, the postoperative examination revealed no lesions of the vagus nerve and the glossopharyngeal lesion was shown to be isolated and selective. 相似文献

A case of aqueductal stenosis following mumps infection is reported, to the authors' knowledge the 12th case in the literature. The pathogenetic events are discussed and the literature reviewed.

The beta-endorphin content in cerebrospinal fluid (CSF) was evaluated in 10 patients with idiopathic trigeminal neuralgia during medical treatment (with or without carbamazepine) and after selective thermocoagulation of the Gasserian ganglion. These values were compared with those obtained in a control group of seven patients without pain problems. No statistically significant difference was found between patients suffering from trigeminal neuralgia and those without pain. Furthermore, neither pharmacological treatment nor surgery changed CSF endorphin values. It is concluded that there is no pathogenetic relationship between trigeminal neuralgia and endorphins. 相似文献

Most orthodontic brackets and archwires made from stainless steel or nickel (Ni)-titanium (Ti) alloys can release metal ions into the saliva. This study measures the amounts of metal released from simulated fixed orthodontic appliances. Sixty simulated fixed orthodontic appliances were manufactured in different ways and divided into four equal groups as follows: new brackets and new archwires (group 1 controls), new brackets and recycled archwires (group 2), recycled brackets and new archwires (group 3), and recycled brackets and recycled archwires (group 4). The bracket bases coated with adhesives were heated at 350 degrees C for 30 minutes. Recycled archwires were sterilized by autoclaving. Each appliance was soaked in artificial saliva of pH 7 at 37 degrees C for 45 days. At the end of this period, a sample of the artificial saliva was collected for analysis. Concentrations of Ni, chromium (Cr), iron (Fe), manganese, copper (Cu), and Ti ions were measured by atomic absorption and recorded in micrograms per liter. Analysis of variance and the Duncan multiple-range test indicated significant differences among the groups (P < .001). The study revealed the following: (1) group 4 released higher amounts of Cr, Fe, and Ti than any of the other three combinations; (2) Ni release was similar in groups 1 and 2 and in groups 2, 3, and 4; (3) the amounts of Cu, Cr, and Ti ions released from groups 3 and 4 were significantly greater than the amounts released from the other two combinations. 相似文献
