Disulfiram is known to produce toxic encephalopathy and peripheral neuropathy. The case of a 37-year-old alcoholic who attempted to commit suicide by taking 22.5 g disulfiram is described. During the first 6 days after the intoxication he was stuporous and had cerebellar ataxia and dysarthric speech. Then he became comatose, and as he recovered from coma, he showed peripheral neuropathy including diplegia faciei and severe tetraparesis. Denervation potentials were detected in both facial muscles and distal muscles of the upper and lower limbs, while conduction velocity was normal. Axonal degeneration was verified by sural nerve biopsy. In addition neurofilamentous axonopathy was documented. The recovery from his paresis lasted 2 years.

From 1972-1974, 228 children began treatment for acute lymphocytic leukemia and were prospectively assessed for neurologic complications. After CNS irradiation (2,400 rad) and intrathecal methotrexate (MTX), they received weekly intravenous maintenance therapy with MTX alone (40-60 mg/m2; 20 patients) or MTX (10-30 mg/m2) with other drugs (208 patients). Signs of leukoencephalopathy appeared in 11 children (nine without CNS leukemia) after 4-15 months of IV MTX alone, and included lethargy, seizures, spasticity, paresis, drooling, and dementia. Before or during the clinical onset, EEG frequencies slowed (all ten patients tested). Radionuclide scans showed periventricular accumulation of 99mTc (9/11 patients) and remained abnormal for greater than or equal to six months in eight patients. Cranial computed tomograms or neuropathology findings (five patients each) demonstrated leukoencephalopathy (nine patients) and radiation-related microangiopathy (ten patients). Severe neurologic and neuropsychologic dysfunctions were present in four long-term survivors.

To determine if sheep scrapie agent(s) in the United States would induce a disease in cattle resembling bovine spongiform encephalopathy, 18 newborn calves were inoculated intracerebrally with a pooled suspension of brain from 9 sheep with scrapie. Half of the calves were euthanatized 1 year after inoculation. All calves kept longer than 1 year became severely lethargic and demonstrated clinical signs of motor neuron dysfunction that were manifest as progressive stiffness, posterior paresis, general weakness, and permanent recumbency. The incubation period was 14-18 months, and the clinical course was 1-5 months. The brain from each calf was examined for lesions and for protease-resistant prion protein. Lesions were subtle, but a disease-specific isoform of the prion protein was present in the brain of all calves. Neither signs nor lesions were characteristic of those for bovine spongiform encephalopathy.

Forty-two cats underwent craniotomy for removal of a meningioma between 1985 and 1991. Median duration of clinical signs before examination was 1.25 months. All cats had inappropriate demeanor: 48% were dull and 38% were lethargic. Neurological deficits included impaired vision in 93%, paresis in 83%, and seizures in 19%. Computed tomography (CT) showed solitary masses in 86% and multiple masses in 14%. Intraoperative complications included hemorrhage and difficulty excising deep or adherent masses. Anemia in 13 of 42 cats was the most common immediate postoperative complication. Ten of 42 cats had no improvement or a more severe neurological status after surgery. Eight of 42 cats died immediately after surgery; 6 of these were anemic. Of the cats that survived the immediate postoperative period, evaluation 10 to 14 days after surgery showed that 97% (33 of 34) were alert and 79% (27 of 34) had returned to normal behavior. Neurological deficits, except for vision impairment, had resolved in most cats. The duration of follow-up varied from 1.3 months to 55.1 months. Ten cats developed neurological abnormalities from 1 month to 44.2 months after surgery; of these, 6 had tumor recurrence or new growth confirmed by CT scan or necropsy. Overall survival was 71% at 6 months, 66% at 1 year, and 50% at 2 years. Age of cat and location of tumor did not significantly affect survival (P = .1034 and .1851, respectively). There were too few precise measurements of tumor size to make a valid statistical comparison of the effect of size on survival. Location or presence of multiple tumors did not affect final outcome.(ABSTRACT TRUNCATED AT 250 WORDS)

Goldberger discovered human pellagra was a non-infectious disease, affecting mostly the small and the timid in overcrowded institutions. Symptoms were diarrhoea, dermatitis and dementia. The staff and older children escaped the disease. They ate the meat and left the small and timid with the gravy. The 'Goldberger syndrome' is observed during competitive feeding of livestock, in ketotic animals and in the zinc depleted which are lethargic and pick all day at their feed. The pellagra preventative factor was later found to be nicotinic acid, derived from the amino acid tryptophan. Deficiencies of copper, magnesium, vitamin B6 (activated by a zinc kinase) inhibit the conversion of tryptophan to nicotinic acid. Stresses, including liver diseases, malabsorption, iron overload, porphyria, marasmus, cold stress, pregnancy, lactation, antibiotics and sulfa drugs, all increase dietary needs of nicotinic acid. Elevated free fatty acids and ketone bodies in the blood are associated with ketosis, zinc depletion and the pre-diabetic state. There is a diminished uptake of glucose by the tissues, a condition also found in parturient paresis of dairy cows when elevated hydrocortisone promotes insulin resistance and hyperglycaemia. This defect in insulin response leads to a diabetic-like state. The major predisposing factor in parturient paresis of dairy cows is hypocalcaemia. Gut absorption of dietary calcium may not meet the primary demands of lactation initiation until bone calcium mobilisation is established.

An outbreak of narasin poisoning in swine is described. Forty nine out of 108 lactating sows died over a period of one month after being fed a ration accidentally contaminated with narasin. Clinical signs included anorexia, respiratory distress, lethargy and posterior paresis, progressing to lateral recumbency and death. Necropsy examination in 3 pigs revealed extensive myocardial and skeletal muscle damage. Analysis of the feed confirmed the presence of high concentrations of narasin.

Twelve naive and nine test-vaccinated horses which developed clinical signs of rabies as a result of the required protocol of a vaccine trial were prospectively observed. Nineteen of the 21 cases were confirmed positive for rabies infection of the brain by fluorescent antibody test. The two horses with negative results had ganglioneuritis of the trigeminal ganglion or lymphocytic perivascular cuffing in the brain stem in addition to clinical signs. Average incubation period was 12.3 days and average morbidity was 5.5 days. Naive animals had significantly shorter incubation and morbidity periods (P < 0.05). Muzzle tremors were the most frequently observed (81%) and most common initial sign. Other common signs were pharyngeal spasm or pharyngeal paresis (71%), ataxia or paresis (71%), lethargy or somnolence (71%). The furious form was manifested in 43% of rabid horses and some of these furious animals initially manifested the dumb form. The paralytic form was not observed. Histopathology was characteristics for rabies. The results of this trial do not reflect on the efficacy of commercially licensed equine rabies vaccines.

A 22-week-old 21-kg female Bernese Mountain Dog ingested a topical antipsoriatic preparation containing the synthetic vitamin D analog tacalcitol. The dog died after a history of lethargy, recumbency, paresis of the hindlimbs, increased rectal temperature, dyspnea, and hematemesis. Histologic examination revealed metastatic calcification in the kidneys, lungs, myocardium, brain, stomach, and tear glands. The appearance of soft tissue mineralization in multiple organs is consistent with hypercalcemia derived from excessive vitamin D uptake. Oral toxicity studies for tacalcitol in the dog are not available, but the present report emphasizes the extraordinary toxic risk of drugs containing this vitamin D analog to dogs.

Kernicterus is a preventable life-long neurologic syndrome caused by severe and untreated hyperbilirubinemia during the neonatal period. High levels of bilirubin are toxic to the developing newborn. In full-term infants, hyperbilirubinemia symptoms include severe jaundice, lethargy, and poorfeeding. Features of kernicterus may include choreoathetoid cerebral palsy, mental retardation, sensorineural hearing loss, and gaze paresis. Kernicterus is not a reportable condition in the United States, and its prevalence is unknown; however, a pilot registry at a Pennsylvania hospital documented 90 cases in 21 states from 1984 to June 2001 (L. Johnson, Pennsylvania Hospital, Philadelphia, personal communication, 2001). This report summarizes case histories of four full-term, healthy infants who developed kernicterus and underscores that to prevent kernicterus, newborns must be screened and promptly treated for hyperbilirubinemia.

Severe hypomagnesemia (0.8 mg/dl; reference range, 1.6 to 2.3 mg/dl), hypocalcemia, and protein-losing enteropathy were identified in a 5-year-old castrated male 3-kg (6.6 lb) Shih Tzu examined because of anorexia, lethargy, paresis, and abdominal distention. Histologic examination of intestinal biopsy specimens revealed lymphangiectasia and lymphocytic, plasmacytic, neutrophilic infiltrates. Initial treatment included administration of magnesium (0.80 mEq/kg [0.36 mEq/lb]) of body weight in a balanced electrolyte solution. This treatment resulted in normalization of the serum magnesium concentration (1.7 mg/dl); resolution of the lethargy, paresis, and tachycardia; and an increase in the serum parathyroid hormone and ionized calcium concentrations. Findings were consistent with secondary hypoparathyroidism attributable to hypomagnesemia. Magnesium concentration should be monitored in all dogs with gastrointestinal tract disease, especially those with protein-losing enteropathy, anorexia, and weakness.
