We report the cases of two patients who developed cranial nerve palsies after drinking ethylene glycol. A 33-year-old man developed multiple cranial nerve deficits nine days after the ingestion of ethylene glycol in a suicide attempt. Clinical findings included profound bilateral cranial nerve VII palsies and severe dysfunction of cranial nerves IX and X.(More)
We report on a 17-year-old boy who developed a marked increase in serum creatine kinase (CK) (9743 U/l) during treatment with risperidone for catatonic psychosis. Known causes of elevated CK such as delirium, malignant neuroleptic syndrome, infection, cocaine overdose, trauma, and intramuscular injections were ruled out. Vital signs remained always within(More)
Polychlorinated biphenyls (PCBs) are ubiquitous environmental toxicants known to adversely affect the nervous system and more specifically the dopamine system. Developmental PCB exposure in rats has been shown to produce alterations in dopaminergic signaling that persist into adulthood. The reinforcing properties of psychostimulants are typically modulated(More)
A patient is described with subacute necrotizing encephalomyelopathy proven by autopsy. A slight increase of blood pyruvate and lactate levels with an increased lactate/pyruvate ratio and frequently increased beta-hydroxybutyrate/acetoacetate ratio suggested a disorder of mitochondrial oxidation. A cytochrome c oxidase deficiency was shown in peripheral(More)
Polychlorinated biphenyls (PCBs) are ubiquitous environmental toxicants known to adversely impact human health. Ortho-substituted PCBs affect the nervous system, including the brain dopaminergic system. The reinforcing effects of psychostimulants are typically modulated via the dopaminergic system, so this study used a preclinical (i.e., rodent) model to(More)
Exposure to polychlorinated biphenyls (PCBs) alters brain dopamine (DA) concentrations and DA receptor/transporter function, suggesting the reinforcing properties of drugs of abuse acting on the DA system may be affected by PCB exposure. Female Long-Evans rats were orally exposed to 0, 3, or 6 mg/kg/day PCBs from 4 weeks prior to breeding until litters were(More)
Polychlorinated Biphenyls (PCBs) are very stable environmental contaminants whose exposure induces a number of health and cognitive concerns. Currently, it is well known that PCB exposure leads to poor performance on inhibitory control tasks. It is also well known that dopamine (DA) depletion within medial prefrontal cortex (mPFC) leads to poor performance(More)
