Case histories are presented for four psychotic patients who ingested large quantities of water and subsequently developed grand mal seizures and serum sodium levels of less than 121 meq/liter. The physiology of psychogenic polydipsia and related disorders is reviewed. The relation of this disorder to temporal lobe seizures and to the use of phenothiazines is considered.

Clinical and Neuropathological data on sixteen cases of progressive myoclonic encephalopathy are reported. This neurological syndrome appears after an average duration of thirty two months of haemodialysis and leads to death in four and a half months, and is characterized by myoclonus, speech disorder, epileptic seizures, and mental-status changes. At first, clinical signs and symptoms are related to haemodialysis, later they become permanent. An early diagnosis is based on EEG which is the only useful laboratory test, demonstrating bisynchronous slow-wave bursts. The caracteristic histopathologic findings are neuronal depopulation, lipofuscin accumulation, and appearance of Neurofibrillary degeneration, especially in Motor cortex, red nucleus and dentato-olivary systems. It seems to be justified to attribute P.M.D.E. to aluminium chronic poisonning; the source of the aluminium intoxication is not aluminium containing phosphate-binding gels but intravenously administreted tape-water. The intracellular binding of aluminium is shown from a histochemical study employing fluorescent stain Morin.

Adult C57BL/10Bg mice, normally resistant to audiogenic seizures, became susceptible when the mothers drank 10 per cent ethanol in water during pregnancy and for 14 days postpartem. Reserpine enhanced the incidence of seizures, and the effect was reversed by 5-hydroxytryptophan but not by dihydroxyphenylalanine. p-Chlorophenylalanine also enhanced the incidence of seizures, whereas alpha-methyl equals p equals tyrosine did not effect. Monsodium glutamate almost completely prevented seizures. These results are consistent with the interpretation that the serotonergic systems may be among those involved in the seizure mechanism induced by fetal and early exposure to ethanol.

Programmed-feeding polydipsia results in a reliable model of chronic alcoholism in the rat. High oral ethanol comsumption and a predictable withdrawal reaction associated with audiogenic seizures are produced. The maintenance of high blood ethanol levels for three weeks in 18 male Charles River rats was associated with audiogenic seizures after 6 or 8 hours of withdrawal. These chronic alcoholic rats had enhanced blood clearance of ethanol. The cerebral cortical crude mitochondrial fraction showed a decrease in total and magnesium-dependent adenosine triphosphatase activity in alcoholic and control (water-fed) rats compared with normal rats.

The pharmacology of Avena sativa has been investigated in laboratory animals following a report that tincture of Avena sativa reduced the craying for cigarettes in man. The tincture, evaporated to dryness, craving for cigarettes in man. The tincture, evaporated to dryness, re-constituted in an equal volume of water and administered by stomach tube or intraperitoneal injection, antagonized the antinociceptive effect of morphine in two separate test (hot-plate and tail flick). Compared with animals made depedent on morphine alone, mice pretreated with repeated injections of morphine plus extract passed a smaller number of stools and tended to jump less after administration of nalorphine. The pressor response to intravenously administered nicotine in urethane-anaesthetized rats was also antagonized by prior administration of Avena sativa. However, the aqueous extract prepared from the tincture did not affect the seizure threshold to bemegride or nicotine or the sleeping time induced by barbitone sodium.

Neonatal rats were exposed to lead (Pb) from parturition to weaning via the milk of dams which consumed 0 (tap water), 0.02% or 0.2% PbAc2 solutions. To determine if this regimen altered physiological and neurobehavioral development, responses to a battery of sensory-motor tests were evaluated during maturation and as adults. The tests were: visual evoked responses (VER), temperature regulation, maximal electroshock seizure patterns, reflex patterns, and neuromuscular performance. Overall results revealed that the Pb-exposed group compared to controls exhibited delayed maturation, altered developmental patterns and long-term CNS disturbances. Additionally, low-level strychnine administration during development caused additive interactions with both Pb groups, uncovering subtle effects of toxicant exposure. These sensitive and quantifiable techniques proved useful for assessing CNS functioning following perinatal insult, and except for the VER, are simple to conduct and cost efficient because they require a minimal amount of personnel training, equipment cost and time invested per animal. These screening tests also suggest further areas of study and may indicate the mechanism(s) responsible for the deficit.

Metrizamide is a nonionic water-soluble contrast medium for neuroradiological studies that is less irritating to the nervous system than other water-soluble agents. Studies in adults have shown that metrizamide has advantages over currently available media, but experience with children has been limited. Sixty-two children have had myelography or ventriculography using metrizamide. The children ranged in age from 11 days to 22 years. Technically satisfactory studies were obtained in every patient. No major complications were encountered. Minor side-effects included headache in 11 children (18%), mild nausea or vomiting in 16 children (26%), and fever in 4 children (6%). Seizures did not occur. One infant in the study subsequently died of unrelated problems; there was no evidence of arachnoiditis at postmortem examination. Metrizamide is a safe, effective contrast medium for neuroradiological use in children.

In 170 patients 184 ventriculographies with water-soluble contrast media were carried out, 60 examinations with meglumine iocarmate (Dimer-X) and 124 with metrizamide (Amipaque). Grand mal seizures occurred in one patient following the injection of meglumine iocarmate. The indications, technique and diagnostic results are reported.

Metrizamide is a water-soluble, nonionic radiocontrast medium that penetrates better into narrow subarachnoid spaces than do oily contrast media or gas. We performed metrizamide optic nerve thecography on five cats with iatrogenic orbital lesions. Optic thecograms successfully demonstrated displacement of the optic nerve, obstruction of the optic nerve sheath subarachnoid space, and extravasation of the contrast medium from a punctured optic nerve sheath. Metrizamide-induced seizures could be prevented by intramuscular preadministration of diazepam.

We have reviewed 14 cases of water intoxication in psychiatric patients. In these cases the possibility of the syndrome of inappropriate antidiuretic hormone secretion (SIADH) was suspected or diagnosed. The SIADH should be suspected in psychotic patients who drink water excessively, develop seizures, disorientation and deterioration of mental status.
